6 Expansion and Strengthening of Runway and Upgradation of Associated Operational Infrastructure and Terminal facilities at Naini-Saini Airport, Pithoragarh (Uttarakhand) for ATR-42 type of aircraft EXECUTIVE SUMMARY The State Government of Uttarakhand through Uttarakhand State Infrastructure Development Corporation Ltd., (USIDCL) proposes to develop/ upgrade the existing airport at Naini-Saini, Pithoragarh to Category 2C airport under VFR conditions for operations of ATR-42 type of aircraft. USIDCL have engaged RITES LTD. (A Government of India Enterprise) as their consultants for planning, design & supervision vide their letter No: 813/USIDCL-131B/11 dt EXISTING AIRSTRIP The existing airstrip at Naini-Saini, Pithoragarh was constructed during 1991 for the administrative use. The airport is owned by the State Government of Uttarakhand. The existing airport occupies an area of about 28 hectares and situated at about 04 km away from Pithoragarh town on Pithoragarh Dharchula State Highway. The existing airport had been planned for operations of Dornier type aircraft. Key features of the exiting airport are as under: Runway : 1300 x 20 m Apron : 50m x 30m Taxiway : 50m x 15m Terminal Building/ATC, Fire Station and Residential Quarters The aerial distances to other important airports nearby from Pithoragarh are as under: Pantnagar - 97 km (South West) Dehradun km (West) Lucknow km (South) New Delhi km (West) Kanpur km (South) DEVELOPMENT WORKS ENVISAGED The following major works have been envisaged by USIDCL for the proposed development. a) Expansion and strengthening of existing runway for operation of ATR-42 type of aircraft under VFR condition RITES Limited 1 DPR Vol - I

The objective is to upgrade the facilities at the existing airport to commence commercial operations (day VFR) of ATR-42 type of aircraft. The aerodrome reference code derived based on the dimensions of design aircraft as per provisions of ICAO (Annexure 14) is 2C and is a key planning parameter for planning of airside facilities. As per RFP, the renovation/ up gradation of existing ATC terminal building is to be carried out for 100 passengers. During meeting with USIDCL on at Dehradun, it was clarified that the new terminal building is to cater 50 incoming and 50 outgoing passengers, totaling to 100 passengers. Using these parameters a layout plan for the proposed development has been drawn. Two Concept Plans were prepared showing the proposed development works of the airport within the available land of the airport and with additional land proposed for acquisition. Both the concept plans were discussed with the officers of USIDCL & State Civil Aviation. It was RITES Limited 2 DPR Vol - I

8 Expansion and Strengthening of Runway and Upgradation of Associated Operational Infrastructure and Terminal facilities at Naini-Saini Airport, Pithoragarh (Uttarakhand) for ATR-42 type of aircraft informed by the Government that no additional land can be acquired and the proposed development works have to be accommodated within the land available. The concept plan for proposed development works of the airport within the available land was discussed in detail and the approval to the concept plan was communicated by USIDCL vide letter dt: OBSTACLE ANALYSIS The existing airport is surrounded by hills all around. Hills existing in the approach 14 are protruding the obstacle limitation surfaces by 100 m. Cutting of these hills to reduce the obstructions to permissible heights will incur exorbitant cost and involve environmental concerns. Hence landing/takeoff in this direction is not feasible. A bituminous road connecting Naini-Saini village is passing through the proposed extension of runway area at 32 end. This road is required to be closed. From the District Administration it has been understood that alternate road connectivity to the village is being provided by the PWD. Few structures present in the vicinity of approach 32 infringe the OLS which are required to be removed or notified. A hill present on the north east side of the runway protrudes the inner horizontal surface of OLS by 427 m. The obstruction in the Inner Horizontal Surface is significant and required to be notified for decision of minimum circling altitude. Due to raising land terrain conditions, proposed compound wall also infringes the transitional surface on the North Eastern stretch at many places. ATC tower is also forming an obstruction due its height and proximity. PROPOSED DEVELOPMENT WORKS Runway The take-off length required for ATR for the maximum take-off weight at ISA+20 C and 1500 m elevation works out to 1620 m. Keeping into consideration the limited length of land available, it is proposed to provide a runway of length 1510 m which will be sufficient for operations of ATR 42 to meet the destinations with in a range of 350 km. This is the maximum length of runway that can be RITES Limited 3 DPR Vol - I

9 Expansion and Strengthening of Runway and Upgradation of Associated Operational Infrastructure and Terminal facilities at Naini-Saini Airport, Pithoragarh (Uttarakhand) for ATR-42 type of aircraft provided within the available land leaving clearances for the boundary wall in the approach. It is therefore proposed to extend the existing runway by m on 14 end and 38.7 on 32 end thus making the total extension to 210 m to meet the runway length requirement. The width of runway for aerodrome reference code 2C is 30m. No shoulders are proposed, as it is not mandatory to provide shoulders for runway of category 2C. Future extension of runway for operations of aircraft like ATR 72 is not feasible as the land is not available on both ends. Taxiway The width of existing taxiway is 15m and is in conformity with ICAO recommendation for ATR 42 aircraft. 5m wide shoulders on either side of the taxiway are proposed for the taxiway so that the over all width meets the requirement of 25 m. Apron Existing apron is located at a lateral distance of 60 m from the runway centre line of runway. This separation distance is inadequate for Code 2C, non instrument runway. The size of the existing apron is 50 m x 30 m. This is also inadequate for parking of 2 ATR -42 aircraft. The wheel path of the aircraft was analyzed and it was found that for smooth parking of 2 ATR 42 aircrafts, an apron of size 90m x 60m is required. Due to unavailability of land for expansion of the terminal facilities, expansion of the aircraft parking apron is proposed in such a way that the aircraft parking positions will not constitute obstruction in the transition. Isolation Bay Due to non availability of space in the airport, isolation bay is not provided. The proposed airport being a low activity airport, in the event of an emergency, the runway ends are to be used as isolation bay with airport operations remaining closed. Exemption to this effect is required to be obtained from DGCA/BCAS. Terminal Building RITES Limited 4 DPR Vol - I

10 Expansion and Strengthening of Runway and Upgradation of Associated Operational Infrastructure and Terminal facilities at Naini-Saini Airport, Pithoragarh (Uttarakhand) for ATR-42 type of aircraft As per area norms prescribed by the Ministry of Civil Aviation in the Report of the Inter- Ministerial Group of September 2008, for peak hour passenger upto 100, an area of 12sqm/php is recommended for Category C level of service. The minimum area requirement as per this thumb rule works out to 1200 sqm. However after making provisions for other amenities, such as offices & passenger amenities, an area of 1860 sqm is proposed for the terminal building to meet the minimum requirements for 50 incoming and 50 outgoing peak hour passengers. ATC Tower A fully functional low activity ATC Tower with a tower cab floor area of 36 sqm is proposed. To meet the minimum line of sight and grade intersection angle of 35, the height of the tower is recommended as 25m above GL with an eye level of more than 15.0 m above the average runway level, which will facilitate un-obstructed view of operational areas as well as surrounding air space. Fire Station Category 4 level of fire protection is required to be provided to meet the requirement of design aircraft. For level of protection 4, minimum 1 No. of Crash Fire Tender is required to be provided. A fully equipped Ambulance shall also support the Crash Fire Rescue Services. A fire station of 546 sqm is proposed to house the CFT, Ambulance and a Jeep. Electric Sub Station The electrical load required for the airport works out to 1 MVA. It is proposed to construct a new sub-station of area 525 sqm to house the transformers. Car Park A total of 40 car parks have been provided for parking. The area has no provisions for future expansion. A separate car parking for staff/ VIP, has been provided for easy access. RITES Limited 5 DPR Vol - I

The objective is to upgrade the facilities at the existing airport to commence commercial operations (day VFR) of ATR-42 type of aircraft. Using these parameters a layout plan for the proposed development is drawn. 3.1 PLANNING PARAMETERS The parameters stipulated in the terms of reference, by USIDCL and used for the master planning are given as under: Aircraft Aircraft characteristics have an important role on airport planning. Both airside and landside planning are based on operating characteristics of the aircraft which will be operated at the airport. In particular, the representative aircraft will determine the runway length and width, the minimum separation distance between runways and taxiways, the geometric of pavements, and the pavement strength. As per objectives, the type of aircraft intended for operations is ATR-42 aircraft. The technical characteristics of ATR-42 aircraft presently in operation with various airlines 4 are tabulated in Table 3.1 & 3.2.

24 Expansion and Strengthening of Runway and Upgradation of Associated Operational Infrastructure and Terminal facilities at Naini-Saini Airport, Pithoragarh (Uttarakhand) for ATR-42 type of aircraft Aerodrome Elevation: The co-ordinates of the Airport at Pithoragarh are Latitude N, Longitude E and the elevation is 1500 m above MSL Terminal Building: It is envisaged (in RFP) to renovate/ up grade the existing ATC terminal building complex for 100 passengers Aerodrome Reference Code: The aerodrome reference code derived based on the dimensions of design aircraft as per provisions of ICAO (Annexure 14) is 2C and is a key planning parameter. Future expansion of the airport is constrained due to hilly terrain all round the airport and non availability of land. The presence of cluster of hills in the vicinity at 14 end (Approach 32) constitute major obstacle, making the runway unfit for operations at this end. For the purpose of planning of facilities, the proposed runway is considered as Non-Instrument code 2C for ATR-42 day VFR operations Meteorology of the Area: There is no meteorological observatory in the district. The following account of the climate is based mainly on the records of the observations in the neighbouring districts where similar meteorological conditions prevail. Variations in temperature are considerable from place to place and depend upon elevation as well as aspect. The data in respect of rain fall is obtained from the office of Distt. Magistrate, Pithoragarh. The data thus obtained reveals following: The average annual rainfall in the area recorded for the period is 1263 mm. The mean daily maximum temperature is about 25 C. As per the data taken from the nearest met observatory located at Nainital, the area provides a visibility of more than 4 km during 75% days of the year. 3.2 OBSTACLE LIMITATION SURFACES The obstacle limitation surfaces have been established as per ICAO stipulations with reference to the proposed extension of runway for operations of ATR-42 aircraft for Non- Instrument Runway, Code 2. For the purpose of establishing obstacle limitation surfaces, the length of the proposed basic strip has been considered as 1630m ( x 60m). Further for calculation of obstacle limitation surfaces, reduced levels of 14 end and 32 end thresholds are taken as m (extended by m) and m (extended by 38.70m) respectively above MSL. The requirement of obstacle limitation surfaces for Approach and Take-off as laid down by ICAO is given in Table 3.3 & 3.4.

26 Expansion and Strengthening of Runway and Upgradation of Associated Operational Infrastructure and Terminal facilities at Naini-Saini Airport, Pithoragarh (Uttarakhand) for ATR-42 type of aircraft Obstructions Based on the field obstacle surveys carried out by RITES, the fixed objects around the airport were studied and their locations (distance and co-ordinates) and elevation have been noted. The information thus gathered has been processed to identify and evaluate the obstacles in the laid down surfaces. The details of obstacles identified are given in Table 3.5. The existing airport is surrounded by hills all around. Hills existing in the approach 14 are protruding the obstacle limitation surfaces by 100m. Cutting of these hills to reduce the obstructions to permissible heights will incur exorbitant cost and involve environmental concerns. Hence landing/takeoff in this direction is not feasible. It can be seen from the table that few structures present in the approach 32 infringe the OLS which are required to be removed or notified. With the removal/notification of these obstructions, landing and take-off is feasible on this side. Many structures protrude the inner horizontal & Conical surface due to raising terrain conditions. A hill present on the north east side of the runway protrudes the inner horizontal surface of OLS by 427 m at a horizontal distance of about 1170 m from runway centre line. The obstructions in the Inner Horizontal Surface are significant and required to be notified for decision of minimum circling altitude. Due to the raising terrain conditions, the proposed compound wall of the airport boundary of height 3.0 m on the North-Eastern side stretch infringe the transitional surface and approach 32 at many places. The proposed ATC tower is forming an obstruction in the transitional surface due to its proximity and height. All these obstructions require notification in the NOTAM and exemption from DGCA. A bituminous road connecting Naini-Saini village is passing through the proposed extension of runway area at 32 end. This road is required to be closed. From the District Administration it has been understood that alternate road connectivity to the village is being provided by the PWD A plan showing details of obstacle limiting surfaces is placed at Drawing No. RITES/AP/PT/GEN/OLS.

34 Expansion and Strengthening of Runway and Upgradation of Associated Operational Infrastructure and Terminal facilities at Naini-Saini Airport, Pithoragarh (Uttarakhand) for ATR-42 type of aircraft 3.3 FACILITY REQUIREMENTS AIRSIDE PAVEMENT & RELATED WORKS Runway Runway Length Requirement The runway length is calculated based on the length required for take-off or landing under standard atmospheric conditions for zero elevation, zero wind and zero runway slope and applying following location specific corrections: Correction for elevation 7% for every 300 m) Correction for temperature 1% for every degree variation above ISA) Correction for gradient 10% for 1% longitudinal slope) The aerodrome elevation for Pithoragarh is 1500 m AMSL. The existing runway gradient is 1.50%. Keeping the extension of runway into consideration, the runway gradient is considered as 1.50%. The aerodrome reference temperature is taken as 25 C. Applying the correction to reference length, the take-off length required for ATR-42 works to 2165m. However, as the total correction for elevation and temperature exceeds 35 percent, the runway length thus arrived has been compared with the take-off and landing length requirement for the aircraft based on the aircraft performance data published by the manufacturer as per stipulations of ICAO. The take-off length required for ATR for the maximum take-off weight at ISA+20 C and 1500 m elevation works out to 1620 m. (Annex - 3.3) Runway Dimensions Keeping into consideration the limited length of land available, it is proposed to provide a runway of length 1510 m which will be sufficient for operations of ATR 42 to meet the destinations with in a range of 350 km. This is the maximum length of runway that can be provided within the available land leaving clearances for the boundary wall in the approach. It is therefore proposed to extend the existing runway by m on 14 end and 38.7 on 32 end thus making the total extension to 210 m to meet the runway length requirement. The width of runway for aerodrome reference code 2C is 30m. No shoulders are proposed, as it is not mandatory to provide shoulders for runway of category 2C. Future extension of runway for operations of aircraft like ATR 72 is not feasible as the land is not available on both ends Runway end safety area (RESA) As per Annexure -14 of ICAO, a runway end safety area shall be provided at each end of a runway strip where the code number is 3 or 4; and the code number is 1 or 2 and the runway is an instrument one. As the runway at Pithoragarh will be of code 2 non instrument, provision of RESA is not mandatory, as per Annexure -14 of ICAO and DGCA Civil Aviation Requirements. However, provision of RESA for all the airports is under consideration by ICAO. Therefore, provision of RESA of length 60m and width 60 m (the maximum possible within the RITES Limited 29 DPR Vol - I

35 Expansion and Strengthening of Runway and Upgradation of Associated Operational Infrastructure and Terminal facilities at Naini-Saini Airport, Pithoragarh (Uttarakhand) for ATR-42 type of aircraft available land) is proposed at both the ends of the runway strip, to protect the aircraft in the event of undershooting or over running the runway, within the available land Runway Strip Graded runway strip of width 80 m (40m on either side of centerline of the runway) is proposed in accordance with ICAO stipulation for aerodrome reference code 2, non- Instrument runway. However, if the airport is to be upgraded to instrument runway Code 2 or Code 3 non instrument runway in future, the requirement of runway strip width would be 150m. (75 m on either side of centre line of runway). In that event, the apron and proposed terminal facilities will form obstruction Taxiways The existing link taxiway facilitates direct exit from the runway at The width of existing taxiway is 15m and is in conformity with ICAO recommendation for ATR 42 aircraft. 5m wide shoulders on either side of the taxiway are proposed for the taxiway so that the over all width meets the requirement of 25 m Terminal Apron Existing apron is located at a lateral distance of 60 m from the runway centre line of runway. This separation distance is inadequate for Code 2C, non instrument runway. The size of the existing apron is 50 m x 30 m. This is also inadequate for parking of 2 ATR -42 aircraft. The wheel path of the aircraft was analyzed and it was found that for smooth parking of 2 ATR 42 aircrafts, an apron of size 90m x 60m is required. Due to unavailability of land for expansion of the terminal facilities, expansion of the aircraft parking apron is proposed in such a way that the aircraft parking positions will not constitute obstruction in the transition. The expansion of Apron showing the wheel path and parking of aircraft is shown in the Annex Isolation Bay Due to non availability of space in the airport, isolation bay is not provided. The proposed airport being a low activity airport, in the event of an emergency, the runway ends are to be used as isolation bay with airport operations remaining closed. Exemption to this effect is required to be obtained from DGCA/BCAS. RITES Limited 30 DPR Vol - I

36 Expansion and Strengthening of Runway and Upgradation of Associated Operational Infrastructure and Terminal facilities at Naini-Saini Airport, Pithoragarh (Uttarakhand) for ATR-42 type of aircraft 3.4 BUILDINGS & ALLIED WORKS Passenger Terminal Existing Building The existing terminal building is located at a lateral distance of 50 m from the edge of the runway. The location and height of the existing building was studied with reference to obstacle limitation surfaces and it was observed that building falls in transition zone and is an obstacle to flight operations. In order to have safe operations and to accommodate the expansion of the apron, the existing terminal building needs to be demolished. Architects Concept Figure 13 - Existing Terminal Architects know that buildings like the airport are a halfway house, a place to wait. Accordingly, the aim is to provide a comfortable place for its users by giving wide openings with a direct view to the outside scenery that makes the user does not feel bored in it. The quality of service, for tourists as well as travelers and their visitors and greeters, is also considered to be at the heart of the terminal design. The emphasis of the planned modernization is therefore to dramatically improve the passenger experience from curbside to airside with a design that adeptly captures the vibrant spirit of the Uttarakhand state and establishes a new, refreshingly convenient functionality. The dynamic new design for the terminal has been evolved within the confined space available for the construction of terminal building and also considering that any future land acquisition proposed for a more lavish architecture may actually not be feasible. The positioning of the buildings & other activities like car parking and road circulation has been finalized within the constrained area available so as to fully optimize on the resources. The terminal building has been planned with split level roofs flowing as the scenic hilltops of the surroundings. Among the most common themes that came to mind were mountains, sunlight, color escapism, openness, trend-setting, movement, and creativity. Such themes called for a design that expresses movement, openness and an expression that leads the eye skyward. The traveler will sense the enormous impact of having a space open to natural light, with both high ceiling and glass surfaces. Design Criteria As per RFP, the renovation/ up gradation of existing ATC terminal building is to be carried out for 100 passengers.

37 Expansion and Strengthening of Runway and Upgradation of Associated Operational Infrastructure and Terminal facilities at Naini-Saini Airport, Pithoragarh (Uttarakhand) for ATR-42 type of aircraft clarified that the new terminal building is to cater 50 incoming and 50 outgoing passengers, totaling to 100 passengers. As per area norms prescribed by the Ministry of Civil Aviation in the Report of the Inter-Ministerial Group of September 2008, for peak hour passenger upto 100, an area of 12sqm/php is recommended for Category C level of service. The minimum area requirement as per this thumb rule works out to 1200 sqm. However after making provisions for other amenities, such as offices & passenger amenities, an area of 1860 sqm is proposed for the terminal building to meet the minimum requirements for 50 incoming and 50 outgoing peak hour passengers. The basic design criteria s that had been considered for the terminal design are: Peak Hour Passenger Traffic Passenger Service & Dwell Times Design Aircraft Level of service Peak Hour Passenger (PHP) Traffic: As per the Terms of Reference, the Peak Hour Passenger rate is as under: Domestic Departure : 50 Domestic Arrivals : 50 Passenger Service & Dwell Times: In view of absence of normative surveys/data for service & dwell times, international norms modified logically, in accordance with local procedures & practices have been considered. Level of Service: IATA s Airport Development Reference Manual recommends Level of Service C as the minimum design objective, as it denotes good service at a reasonable cost. The proposed Terminal is designed for a mixed Level of Service B & C, which ensures that there is good level of service, conditions of stable flow, acceptable delays & good levels of comfort RITES Limited 32 DPR Vol - I

38 Expansion and Strengthening of Runway and Upgradation of Associated Operational Infrastructure and Terminal facilities at Naini-Saini Airport, Pithoragarh (Uttarakhand) for ATR-42 type of aircraft.iata Concept of Level of Service The proposed Terminal Design has incorporated the following principles & features: Continuous Flow & Optimum Utilization of Spaces: According to Airport Development Reference Manual (IATA), Passenger Flows should be designed to minimize inconvenience and confusion as passengers proceed through the network of Terminal Subsystems. Also for ease of Passenger Movement, it is desired that there are minimum changes in levels & no conflicts. RITES Limited 33 DPR Vol - I

39 Expansion and Strengthening of Runway and Upgradation of Associated Operational Infrastructure and Terminal facilities at Naini-Saini Airport, Pithoragarh (Uttarakhand) for ATR-42 type of aircraft The proposed Terminal is designed on a single level for maximum comfort of passengers. The interconnectivity of spaces/processes ensures that there is an efficient & seamless flow between the city side and airside elements. Also since the project area is in a semi hilly & sloping terrain, therefore the entry/exit level of the passenger terminal building has been placed 2M below the apron level so as to economise on earthwork costs and avoid the building becoming an obstruction in the transition surface of OLS. Accordingly, the apron is connected to the departure & arrival gates by gently sloping ramps. PLAN OF PROPOSED TERMINAL BUILDING Ease of Baggage Handling Activities: Baggage handling is a significant element of passenger processing & is of major importance to a smooth airline operation at the airport. The system must be able to sort large numbers of bags quickly & with a high degree of performance reliability. Also the system should not conflict with the flow of passengers, cargo, crews or vehicles. In the proposed terminal, the baggage is handled at independent locations towards the airside, easily accessible so as to provide for ease in activities. RITES Limited 34 DPR Vol - I

40 Expansion and Strengthening of Runway and Upgradation of Associated Operational Infrastructure and Terminal facilities at Naini-Saini Airport, Pithoragarh (Uttarakhand) for ATR-42 type of aircraft Climatic Considerations: Climate plays an important role in the efficiency of building systems & their economics. The roof of building is provided with natural light facilities at 3 locations covering the entire length of building. The provision of natural light in the building will reduce the power requirement and create a pleasant environment. CROSS SECTION THRU THE TERMINAL BUILDING The proposed design of the terminal creates natural free spaces within the building form in such a way that a large portion of the building remains under natural light most of the times. Also, the glass windows on the building facade are adequately covered by projections so as to control the heat exchanges. Form & Height: An airport is an important landmark of the city & the zone it caters to, it portrays the importance of that region in the national scopes. Therefore the character & form of the building is always an important display of the regions capabilities. The elevation of the building has been approved by the USIDCL after taking care of local architecture and surroundings. The proposed design of split height roof with sloping projections is in line with the local architecture.

41 Expansion and Strengthening of Runway and Upgradation of Associated Operational Infrastructure and Terminal facilities at Naini-Saini Airport, Pithoragarh (Uttarakhand) for ATR-42 type of aircraft Sizing And Allocation Of Areas The sizing of any facility is the most important aspect of economics in airport development programs. Many Operational Research techniques have been developed for sizing of the terminal facilities and the consultants have adopted IATA norms suitably varied in accordance with the degree of statistical information available and other associated factors. The consultants have relied upon internationally accepted norms for dwell times besides information & experience gained in the field of airport planning. Thus the assessment of terminal capacity requirements is based on peak hour passenger through put & average processing times for each facility. The sizing of areas is a process dependent upon the occupancy of areas by passengers/visitors and the facilities provided therein. AREA ALLOCATION CHART Before actually calculating the capacity of a terminal using the assumptions listed above, it is very important to decide the performance standards at each facility. It may be stated that the performance standards have been assumed by the consultant on the basis of the overall dwell times prescribed for arriving or departing passengers by ICAO as 45 and 60 minutes. It may also be stated that in the ICAO circular, the dwell time for departures is from the time that a passenger reports at the check in counter to the time he boards the aircraft. However considering the traffic at Pithoragarh airport the dwell time has been assumed from the time that the passenger enters the Terminal Building to the time when he boards the aircraft.

59 Expansion and Strengthening of Runway and Upgradation of Associated Operational Infrastructure and Terminal facilities at Naini-Saini Airport, Pithoragarh (Uttarakhand) for ATR-42 type of aircraft Both type of pavements are designed for a design life of twenty years Rigid pavements do not require major maintenance through out their design life. Only periodic Joint filling is needed. The upfront cost of construction in case of rigid pavement is more Flexible pavement inherently needs rejuvenation of surfacing every six to nine years as the binder material (bitumen) has the limitation of ageing within this period. The flexible pavements have the distinction of very quick maintenance and even during resurfacing the operations can continue with some limitations. In case of rigid pavement even a localized repair to concrete is cumbersome and may require closer of airfield for days together. Cement concrete is a very sensitive material in its green form which requires far greater control during the construction and possibilities of oversight can not be totally ruled out. Flexible pavement is sensitive to aircraft fuel and is not a preferred option in the areas where oil spillage is anticipated In the areas of critical climatic conditions where there is significant difference in day and night temperature, rigid pavement is traditionally not a preferred option, temperature differential in such cases leads to extra thickness and eventually more cost. Though providing rigid pavement may eliminate the periodic overlay needs but requires more up-front costs. Moreover, repairs in rigid pavement, if needed, are very cumbersome. In consideration of the fact that the existing runway is constructed with flexible pavement, and also the merits and demerits on the choice of pavement as explained above, flexible pavement is proposed. Generally, concrete pavement is preferred for the Apron to avoid erosion of pavement surface due to oil spillage. However, bituminous pavement has been proposed keeping in view that the number of operations and aircraft refuelling at this airport will be very minimum Design Aircraft The scope of work envisages that the airport pavements are to be designed for ATR-42 type of aircraft Parameters Other design parameters used in airfield pavement design are listed below: No. of Departures 1200 per annum Design life 20 years Sub-grade CBR 4% RITES Limited 7 DPR Vol - II

Step - 1: Total Pavement Thickness: From the flexible pavement design curves for dual wheel configuration (figure 4-37 of the Aerodrome Design Manual part III of ICAO ), the total thickness of the pavement is calculated using above parameters for the design aircraft. The figure 4-37 of the Aerodrome Design Manual Part III of ICAO is enclosed at Annex 4.2. The total thickness of pavement thus works out to 21 i.e cm. (including wearing course). Step-2: Thickness Requirement Over Sub base: Similar to the method adopted for determining the total pavement thickness, the thickness of sub base course is also determined. Considering design CBR value of the sub base as 20%, with rest of the input remaining unchanged, the thickness over sub base is derived. The thickness over sub-base thus obtained is deducted from the overall thickness to arrive at thickness of base layer. The combined thickness of surfacing and base course works to 15 cm and thus the required thickness of sub base works out to 37.5 cm. (52.5 cm-15 cm) Step-3: Thickness of Bituminous Surfacing: The note in figure 4-37 of the Aerodrome Design Manual part III of ICAO indicates that the thickness of bituminous surfacing for critical areas shall be 100 mm. It may be noted that the wearing course is required to perform following functions. To resist the shearing stresses caused by the aircraft loads. To provide the impervious surface to prevent ingress of surface water to the base courses and lower layers, which eventually damages the pavement structure. To provide a texture of non-skid quality, without causing undue wear on tires. To provide a well-bonded surface free from loose particles which are considered to be a potential threat to the aircraft Step-4: Base Course Thickness: The thickness of wearing course is deducted from the thickness over the sub-base arrived at Step-2. The thickness over base is further cross checked from the figure 4-45 of the Aerodrome Design Manual part III of ICAO (for determining the minimum base course thickness). The figure 4-45 of the Aerodrome Design Manual Part III of ICAO is enclosed at Annex 4.3. As per the same, the minimum thickness to be provided for base course is 15 cm. To summarize, the total pavement thickness required is 525 mm and the same is distributed in the layer system of the pavement works as under: RITES Limited 8 DPR Vol - II

Following are the requirements of good detailing: Reinforcement detailing should be simple for fabrication and placing. Cracking of concrete should be within the permissible limits. There should not be any free paths for propagation of cracks without being traversed by reinforcement. Joint and discontinuities should be capable of withstanding the same forces as the adjoining sections. Reinforcement should not deviate excessively from the direction of the tensile stresses. Reinforcing steel of same type and grade is used as main reinforcement in a structural member. Provisions of IS and IS is followed for the purpose of detailing of reinforcement Summary & Conclusion For the analysis of this buildings dead loads & imposed load as per the requirements of IS part II are considered. The buildings shall be analyzed for earthquake loads for zone V for different load combinations as per the provisions of IS Concrete used for all R.C.C. elements shall be of minimum grade M25 & reinforcement shall be Fe 500 conforming to IS Detailing of reinforcement is provided for all R.C.C structural components as per IS and IS Prime importance shall be given to satisfy durability requirements as per clause 8.2 of IS to make the building long lasting.

SP (16) Design aids SP (34) - Detailing hand book 4.5 STORM WATER DRAINAGE SYSTEM The purpose of storm water drainage system is to convey runoff to natural drains i.e. rivers, nalah, ponds or towards natural drainage. The factors like intensity of rainfall, topography of the area, imperviousness factors etc are considered while designing the system economically and adequately. Topography The topography of the area plays an important role in planning storm water drainage system. RITES Ltd. has carried out the topographical survey of the project area, which indicates that the reduced level of existing site varies from 1496 m to 1518 m Design Criteria The drainage system has been designed as open channel of flow, rectangular in shape and constructed with reinforced cement concrete (RCC). On the basis of collected data and existing guidelines/manual/code for drainage design, salient design criteria have been adopted as described below Minimum width: 250 mm Minimum depth: 250 mm Minimum freeboard: 100 mm Minimum velocity: 0.6 m/sec. Non-silting and non-scouring flow Rainfall intensity of 50 mm/hr Imperviousness factor of 0.70 for commercial and industrial area and 0.2 for parks and undeveloped area. Road water is proposed to be collected by providing lateral drain and gully chamber with grating wherever necessary. Runoff The entire precipitation over the drainage area does not reach the drain due to its characteristics such as imperviousness, topography including depressions and water pockets, shape of the drainage and duration of the precipitation. A fraction of the total precipitation only reaches to the drain. RITES Limited 18 DPR Vol - II

71 Expansion and Strengthening of Runway and Upgradation of Associated Operational Infrastructure and Terminal facilities at Naini-Saini Airport, Pithoragarh (Uttarakhand) for ATR-42 type of aircraft For the calculation of the runoff, Rational method is used; Q = 10 * C * i * A Where Q is the runoff in m 3 /hr; C is the Coefficient of runoff; i is the intensity of rainfall in mm/hr and A is the area of drainage in hectares.. Rainfall Intensity The meteorological observatory to the project site is located at Pithoragarh, from where daily rainfall data for nine years are collected to get the rainfall intensity for the project. On the basis of available data, it is seen that maximum daily rainfall is 157 mm which has occurred in September Considering the maximum daily rainfall of 2 hourly, 4 hourly, 6 hourly and 8 hourly, rainfall intensity in mm is calculated which is tabulated below. The average rainfall intensity in the month of September comes to mm/hr; it has increased by 20% for unforeseen conditions. Hence, it is safer to adopt 50 mm per hour rainfall intensity for design purpose. TABLE 4.5 RAINFALL INTENSITY AT PITHORAGARH Maximum Rainfall Intensity in mm/hr Rainfall (mm/day) Hr 4 Hr 6 Hr Month 8 Hr mm/hr mm/hr mm/hr mm/hr January February March April May June July August September October November December Coefficient of Runoff The rainfall which finds its way to the drain is dependent on the imperviousness factor and the shape of contributory area apart from the duration of storm. As per CPHEEO manual on Sewerage and Sewage Treatment the imperviousness factor i.e. coefficient of runoff is taken as 0.70 for commercial and industrial area. The Pithoragarh airstrip would have activities like passenger and cargo movement, and for the same infrastructure has need to be developed. Hence it is categorized under commercial/public area.

72 Expansion and Strengthening of Runway and Upgradation of Associated Operational Infrastructure and Terminal facilities at Naini-Saini Airport, Pithoragarh (Uttarakhand) for ATR-42 type of aircraft Manning s Formula Estimated design flows depend to a large extent on the assumptions, the accuracy of which is variable. Inspite of this, care is required to select an accurate friction flow formula as to avoid computing errors. However, the design practice is to use the Manning s formula for open channel flow. Rectangular drainage system is designed with RCC Cement concrete in partial flow condition at atmospheric pressure. Being the non pressure conditions in the open channel Manning s formula is suitably used for the design purpose. The coefficient of roughness for RCC works for rectangular drains is taken as as per CPHEEO Manual on Sewerage and Sewage Treatment. For Rectangular Drains: V = (1 / n) X R 2/3 X S 1/2 And R = (B X D) / (B + 2D) Q = (1/n) X (R) 2/3 X S ½ X A Where, Q= Discharge in m 3 /s S = Slope of Hydraulic Gradient D = Depth of the drain in m V = Velocity in m/s n = Manning s coefficient of roughness Proposed Drain Size Based on design methodology as discussed above, size of the rectangular drains are computed and summarized in Table 4.6 below along with slope, length, invert level, formation level, velocity etc. The fall is worked out by multiplying the length of drain with slope. The layout plan for the drainage system has been prepared indicating node/junction points as depicted on the respective drawing. The design table for width, depth, slope, invert level with respect to node is given for ready reference on the same drawing.

Accordingly, this section deals with the materials required for construction purposes. It may be clarified that the sources identified in this Chapter are for the purpose of formulation of this report. The bidders for the work shall be free to choose their own sources. In order to systematically identify the materials and assess their suitability/ availability the project has been divided into several components. Then a list of materials required for each component has been prepared. In the subsequent sections, each material has been separately discussed. To collect information regarding the availability of major materials a survey was conducted in the months of Dec-2011 and January 2012 in and around Pithoragarh. Representative sampling and testing was carried out on the major materials to assess their suitability, in general, for various types of construction proposed in this project. Detailed testing of materials, as per the normal practice, will be done at the time of commencing construction activity. 5.1 PROJECT COMPONENT Keeping in view the facilities required at the proposed airport, the entire work can be broadly divided into following components for the purpose of assessing material requirements. Pavement Works (Runway, Taxiway, Apron, Peripheral Road and Parking Areas etc.) Building Works (Terminal Building, Air Traffic Control Tower, Fire Station, Substation etc.) Electrification Works (Internal and External) Miscellaneous Works 5.2 MAJOR MATERIALS Component-wise major materials required for the project are as under: a) Pavement Works: Stone aggregate (various sizes) Bitumen Bitumen emulsion Earth RITES Limited 1 DPR Vol - III

83 Expansion and Strengthening of Runway and Upgradation of Associated Operational Infrastructure and Terminal facilities at Naini-Saini Airport, Pithoragarh (Uttarakhand) for ATR-42 type of aircraft b) Building Works: Stone aggregate (various sizes) Earth Sand Cement Reinforcement Steel Bricks c) Internal and External Electrification Works a. Cables (various sizes) b. Transformers c. DG set d. HT and LT Panels d) Fittings and fixtures e) Miscellaneous Works: For miscellaneous works, like drains, boundary wall, watch towers etc. major materials will be generally same as for the building component mentioned above. Detailed description with regard to source and quality (testing) of these materials is given in the following sections. 5.3 STONE AGGREGATE Source: No major stone aggregate quarry is available in the vicinity of site. Although some small quarries do exist nearby the site but during the survey it was observed that the quantity and quality of the materials was not sufficient to cater to the needs of the project. The matter of availability of stone aggregate was discussed with local engineers including client. It emerged that stone aggregates and stone dust is available in large quantities for commercial consumption at the Government approved quarry of Haldwani. For large quantity of stone aggregate required for the project, Haldwani quarry will be the most viable source. Connectivity from Haldwani is excellent through national and state highways for transportation of the material. Quality & Quantity: The quantity of stone aggregate required is 30,000 cum approx. Samples of stone aggregate collected from Haldwani quarry exhibited good strength. Impact and Crushing values observed are in the range of 15% and 19% respectively. These values are within the permissible range as per IS: 383 both for pavement works as well as building works. The aggregate was also tested for water absorption. It has been reported that the water absorption is 0.6% which is good for concrete and asphalt mixes as per IS:456 and MOST specifications RITES Limited 2 DPR Vol - III

Bulk requirement of the project cannot be met from any local sources. IOCL is the leading manufacturer and distributor of bitumen and bituminous products like emulsion, CRMB, PMB etc. Nearest Source for bitumen is IOCL refinery at Mathura which is 500 km from the site. CRMB is available from Koyali, Mathura, Panipat, Haldia and Chennai Emulsion is available from Haldia and Panipat. PMB( Polymer modified bitumen) is available from Koyali Refinary Approximately 710 MT of Bitumen of grade VG 30 (grade 60/70) shall be required for the project. The Marketing Points of IOCL which can supply bitumen and other product to site are at: Haldwani : Only Packed bitumen is marketed from this point. RITES Limited 3 DPR Vol - III

85 Expansion and Strengthening of Runway and Upgradation of Associated Operational Infrastructure and Terminal facilities at Naini-Saini Airport, Pithoragarh (Uttarakhand) for ATR-42 type of aircraft Mathura Refinary: Located in Uttar Pradesh on National Highway-2, it is one of the largest refineries of India. This refinery can supply all the bituminous materials required for project in bulk as well as in packed form. Panipat Refinary: Located in Haryana, this refinery can supply all the bituminous materials required for projects but the lead from the site is more as compared to Mathura. Apart from IOCL refineries, private sector refineries Namely Reliance Industries Ltd. (RIL); and Essar oil ltd located in Jamnagar, Gujarat also supply bitumen. Although the Bitumen shall be supplied by the contractor and it is his prerogative to arrange the materials from any of the refineries but the consultants has considered Mathura refinery as source for bitumen and other products for estimation considering the availability and quality of the IOCL products from Mathura. Also the lead from Mathura refinery is less.(approx. 500 Kms.) as compared to Panipat, Essar and Reliance refineries. Haldwani sales point is ruled out as the bulk quantity requirement can not be supplied from this point. IOCL Mathura is considered as the main source of Bitumen for this project. As IOCL Mathura has got the required quantity and proper quality of bitumen available, no alternate source is proposed for procurement of bitumen. Also IOCL refinery at Mathura is nearest as compared to any other source. Bitumen Emulsion The Bitumen Emulsion can be procured from HINCOL from Roorkee. As this is a reputed source, no other alternate source is suggested for this material. 5.5 GOOD EARTH Source: Huge quantity of good earth is required for preparation of the sub grade particularly in areas of extension of runway. Good earth is not available in nearby areas in large quantities. Geo-technical investigations have revealed that the earth available in the site is largely clayey in nature which shows high swelling index. However, due to non availability of good earth nearby there is no option but to use the earth available within the site with suitable granular layers underneath. Quantity and Quality: It is estimated that 120,000cum. of earth is required for the project. This quantity will be catered from the cuttings generated from excavation work to the extent of 115,000 cum. Balance earth will have to be arranged by the contractor from some other source.

This sand has approximately 2% silt which is not considered harmful. In case sand is not available from Ghat/ Panar for some reason it can also be transported from Haldwani. Handwani being far, this sand will be costlier but may have to be used to maintain the pace of work if so warranted. Quantity and Quality: Total approximate requirement of sand is estimated to be 15,000 cum. Ghat/ Panar quarry, enquiry revealed, can supply the sand. It is expected that with some stock piling the requirement of sand can be managed. Ghat/ Panar sand has been tested for and the values observed are as follows.

Consultants reviewed the existing infrastructure for suitability of the existing facilities to cater for an Airport for operation of ATR- 42 aircraft and Airport of category 2C within the available land of 28 Ha. The location and height of the existing terminal building was studied with reference to obstacle limitation surfaces and it was observed that building falls in transition zone and is an obstacle to flight operations for ATR 42 type of aircraft and for airport of category 2C. In order to have safe operations, the existing terminal building needs to be demolished. (Obstruction surveys and report discussed in detail in Chapter-3, Vol.1) TABLE- 6.1 STRUCTURES FALLING WITHIN AIRPORT LAND TO BE DEMOLISHED S.No. Structure to be demolished Remarks in the existing boundary 1.

The cost index for DSR 2007 is 100 and the cost index of DSR 2012 is 149. The cost index of Pithoragarh was arrived as 194 by taking market rates of labour and material during Jan The detailed calculation showing the cost index of Pithoragarh as on Jan 2012 is attached with this report. It has been observed that the rates of materials at Pithoragarh are higher as all the major building materials such as Cement, Steel, bricks, stone aggregates etc. are to be brought from Haldwani which is over 200Km from site. The rate analysis has been carried out for non schedule items based on market rates. It was also observed that the PWD schedule at Pithoragarh does not show the actual rates of Bituminous works. Thus the rate analysis of pavement works has been carried out based on standard data book published by MoSRT&H (MoST) and supported by actual market rates.

Executive Summary Page ii

240 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand Physiography: The district is naturally landscaped with high Himalayan Mountains, snow capped peaks, passes, valleys, alpine meadows, forests, waterfalls, perennial rivers, glaciers and springs. Topographically the district is having rugged terrain with high cliffs and intersected by deep gorges. The altitude of the district varies from 1200 m to 4500 m above MSL. The slope of the district varies from very steep slope to steep slope (>600m/km to m/km). Geology and Minerals: The project area falls in lesser Himalayas (metamorphism mostly reversed) and the geologic period of upper proterozoic. The minerals available in the Pithoragarh district are Copper, Magnesite, Soapstone, Arsenic, Sulpher, Kyanite, Graphite, Slate and Limestone. Soils: Different soils available in the district are skeletal soils, mountainous, submountainous and snow fed soils etc. The soils within the 10 km radius from airport are sub mountainous soils. These soils are rich in humus content and generally dark brown or black in colour. Land Use Pattern: Land cover of the 10-km radius study area with reference to the Airport has been derived using latest cloud free satellite imageries. From the data, agriculture occupies about 21%, forest occupies about 62%, built-up area occupies 3%, waste land occupies 10%, sparse vegetation is about 1.8% and roads occupies about 0.5%. Seismicity: The state of Uttarakhand falls in a region of high to very high seismic hazard as per Global Seismic Hazard Assessment Program (GSHAP) data. As per the revised seismic zoning map of India, the project area falls in Zone - V of the classification (IS-1893: Part-I: 2002). Drainage: The profile of the district is full of rugged and undulating terrains with the exceptions of the deep gorges, steep and narrow valleys carved out by the rivers and good number of other turbulent streams that drain out all over the district. In the project area streams are the main source for the drainage system Water Environment The district is abundant in rivers most of which are originated within the district. The occurrence of springs is a common phenomenon in the district. The springs have been developed for drinking and irrigation in most places of the district. Four samples were collected in the project area for water quality analysis, which includes two surface water samples and two bore well (ground water) samples. Water from these sources should be treated before using it for drinking purposes Ambient Environment In order to assess the impact on existing ambient environment due to the project, it is necessary to have baseline status of ambient environmental parameters.

241 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand Meteorology: The monsoon season generally exhibits from the mid of June to mid of September. Winter season is from October to March and summer season is from April to mid June. Generally January month is the coldest month of the year whereas month of May is hottest month. Relative humidity will be above 50% throughout the year. Air Quality: Air quality monitoring was carried out at 4 locations within/ nearby vicinity of the proposed project, for twice a week for one season. Seven major air pollutants viz. particulate matter (PM 10 & PM 2.5 ), Sulphur Dioxide (SO 2 ), Oxides of Nitrogen (NOx), Carbon Monoxide (CO), Lead (Pb) and Hydro Carbons (HC) representing the air quality was monitored. The air quality monitoring results indicate that all parameters were noted within the limits for residential areas except at Naini village where PM10 and PM2.5 are exceeded to permissible limit for first 24 hrs monitoring out of 48 hrs continuous monitoring. Noise Environment: Noise levels were recorded on hourly basis for 24 hours in order to have an assessment of the Day and Night time noise levels. Leq for day and night at all locations exceeds the National Ambient Noise Standards for Residential Zone. The main source of noise in the project area is the traffic movement on the road Ecological Environment The proposed project area for the airport and in its neighborhood within 10 km radius has no wild life sanctuary or national park. Uttarakhand state is rich in forest resources. Due to topographical variation and diverse climatic conditions a variety of forests are found in the state. There are 6 reserved forest blocks around the project area out of which Saurlekh block is the nearest at an aerial distance of about 1.75 km from project area. Prominent trees present in the project area are chir, peepal pahari, meil, kharikya and naspate. Common fauna found in the project area are cattle, buffaloes, sheep, and goat. No rare and endangered species are found within the project area. 4. ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES 4.1. Impacts due to Project Location Displacement of People: No displacement of people due to the proposed project is anticipated; however one school exists near to the boundary of the project which needs to be displaced or relocated. Loss of land / Change in land use: No land acquisition is involved for the proposed project, since the required land is in possession of USIDC, and free of any kind of encumbrance. The proposed development will enhance the aesthetics due to development of a modern building and the surrounding horticulture/landscaping. Loss of Infrastructure: One school exists near to the boundary wall of the airport which needs to be relocated. A bituminous road connecting Naini-Saini village is passing through the proposed extension of runway area at 32 end. This road is required to be closed. Executive Summary Page iv

242 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand Encroachment into Forest/ Wildlife Habitat Corridor: Loss of trees or shrubs is not anticipated due to the proposed project activities. The project area does not encroach into any Forest Land or Wildlife Habitat Corridor Land. Loss of Historical, Cultural and Religious Monuments/Structures: No historical, religious or cultural monuments will be lost due to the project location or its activities. Risk due to Earthquakes: The airport area falls in Zone V of the seismic zoning classification of India. The construction of airport will require use of appropriate design technology so that they can withstand the seismic forces. Necessary factor of safety and appropriate coefficient would be incorporated in designing the structures under the worst combination of forces Impacts due to Project Construction Impact on Soil Quality/Erosion: The topsoil shall be disturbed due to various construction activities. Exposure of loose soil to rain water will increase turbidity in the run-off; however, this impact is limited to the possibility of excavated surfaces prevailing in the rainy season. Health Risks and Cultural Effects: Health risk during construction phase, include disease hazards due to lack of sanitation, vector borne diseases and hazards due to local carriers. About 100 people are expected to be working during peak construction period at project site. Water Use and Quality: The water quantity of 54.5 KLD will be required during the proposed construction period including drinking, toilets and construction activities, which shall be arranged by the contractor from nearby surface water source. Wastewater generation from workers toilets is assessed to about 3.6 KL every day. Air Pollution: During the construction phase, PM is expected to be the main pollutant associated with construction activities. The proposed land is fairly flat, so extensive formation work is not expected during this phase. It is assumed that most of the excavated material shall be used within the project, with minimal cut and fill material to come from outside the site. Noise Pollution: The impact of noise produced during the construction will be limited to a distance of about 75 meters at which, the noise level of various equipment will come down below 55 db (A). The construction activities would not have a significant impact on existing environment out of 75m from the construction place. However, these impacts would be temporary in nature. Impact due to Solid Waste Disposal: Inorganic solid waste generated shall be recycled for use in the base layers of paved area i.e. parking pavement and in road construction. The workers along with other supervisory staff are likely to generate about 20 kg of municipal waste every day, which need be disposed properly. Executive Summary Page v

Impacts due to Project Operation Air Pollution: During operation phase of the airport, the source of air pollution will be aircrafts operation and vehicular pollution due to passenger cars. Pollution load due to 20 cars is calculated by assuming passenger travelling on personal vehicle will be petrol car. The combustion conditions and fuel consumption during the various phases of flight (taxi, take off/landing, cruise) will have different emission factors. Emissions during operation phase have been worked out using aircraft emission factors. Noise Pollution: Source of noise at airport is due to the passenger car and aircraft movement. The impact on ambient levels due to vehicular traffic will be marginal limited to parking area of airport. The major source of noise from aircraft is the machinery noise from fan, compressor, turbine blades, engines and the primary jet. For estimation of noise contours around the airport, Integrated Noise Model (INM) version 7.0C is used. In the study, Leq and Maximum sound levels (Lmax) are used to assess the aircraft noise and depicted through noise contour. Impact on Water Environment: After the completion of the project 14.5 KLD would be required for all the facilities like drinking, floor washing and horticulture purposes. The water demand during operation phase will be met from the Municipal water supply. Daily sewage flow works out to 9.9 KLD, which will be treated through packaged Sewage Treatment Plant (STP). Airport Runoff and Drainage: For effective storm water drainage system, a RCC drainage network has been designed. The airport area is divided into 11 zones for early discharge of the storm water. Some part of the storm water from runway, terminal building, apron, and taxiway is being collected separately for rain water harvesting. Impact on Solid Waste Disposal: Operation of airport generates solid waste from routine office activities and restaurant. The assumed rate of generation of solid waste will be 6 kg/day considering 100gm/person/day. Collection and removal of refuse from airport area are important for effective vector control, nuisance abatement, aesthetic improvement, fire protection and bird control. 5.

250 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand places can reduce pollutant release from the vehicles. During operation it is proposed to use Ground Power Unit (GPU) in place of Auxiliary Power Unit (APU). This will facilitate less exhaust gases at airport. Noise Control Measures: Suggested noise reduction flight operational measures and noise reduction measures should be followed during parking at airports. When safety and weather permit, pilots should follow voluntary noise abatement guidelines. Efforts are being made to reduce aircraft noise during parking at airports by using Ground Power Units (GPUs) instead of APUs. Airport s authority should impose a mandatory noise abatement program, or to restrict access for older aircrafts which produces heavier noise. Waste Water Treatment: Total quantity of domestic waste water generation will be 9.9 KL/day. The generated waste water is collected and treated through packaged sewage treatment plant of 15 KL/day. The treated waste water will be used for cleaning, flushing and gardening. Solid Waste Disposal: The project is estimated to generate about 6 kg of solid waste every day. Solid waste generated during the operation phase would be paper, cardboard, glass, metal, plastic containers, compostable foods, restaurant oil and grease, batteries, fluorescent lights, wood pallets, tires and electronics. Most of them are recyclable materials. Horticulture/Natural Grass Turfing: Landscaping of the areas within the premises of airport shall be taken up during construction period.

BACKGROUND CHAPTER - I INTRODUCTION Transportation network of the country contributes important part towards the economic development of the country. Since the economic liberalization of the 1990s, development of infrastructure within the country has progressed at a rapid pace, and today there is a wide variety of modes of transport by land, water and air. The transportation system of the nation is well-set and efficiently managed and is a key player in maintaining the financial development of the country. Rapid economic growth in India has made air travel affordable. The State Government of Uttarakhand through Uttarakhand State Infrastructure Development Corporation Ltd., (USIDCL) proposes to develop/ upgrade the existing airport at Naini-Saini, Pithoragarh to Category 2C airport under Visual Flying Rules (VFR) conditions for operations of ATR-42 type of aircraft NEED OF THE PROJECT The existing airstrip at Naini-Saini, Pithoragarh was constructed during 1991 for the administrative use. The airport is owned by the State Government of Uttarakhand. The Government of Uttarakhand intends to develop the existing airport for domestic purposes OBJECTIVES AND SCOPE OF THE STUDY The objective of the study is to safeguard the Environment due to up-gradation of infrastructure facilities during construction and operation phases of the project. The Government of India (GOI) has made the Environmental Clearance mandatory for airports vide their EIA notification of 14th September, 2006 prior to construction activities of the project. RITES Limited has been assigned the task of preparing the EIA report as per the approved Terms of Reference given by Ministry of Environment and Forest (MoEF) vide letter no F.No.10-37/2012-IA.III dated June 25, 2012 which is given at Annexure 1.1. The Scope of Work of the Environmental Impact Assessment (EIA) study for the development of infrastructure facilities at the airport is briefly described as under: Submit the compliance status to the conditions of EC, Consent orders along with valid consent orders. Examine baseline environmental quality along with projected incremental load due to the proposed project/activities. Examine and submit the details of Noise modeling studies and mitigative measures. Submit the details of validation of the modeling i.e. comparison of monitored value with predicted value. Examine the details of water requirement, use of treated waste water and prepare a water balance chart. Rain water harvesting proposals should be made with due safeguards for ground water quality. Maximize recycling of water and utilization of rain water. Chapter - 1 Page 1

252 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand Examine details of Solid waste generation, treatment and its disposal. Identify, predict and assess the environmental and sociological impacts on account of the project/activities. Submit details of corporate social responsibilities (CSR). The EIA guidance manual of MoEF for the air ports shall be considered while preparing the EIA report APPROACH AND METHODOLOGY The approach of the study is to follow the sequence of steps adopted in an EIA study. The basic concept is to ascertain the existing baseline conditions and assess the impacts as a result of construction and operation of the project. The changes likely to occur in different components of the environment viz. physical, biological / ecological environment and socioeconomics of the project area are studied, analyzed and quantified, wherever possible. The parameters for data generation and impact assessment are decided based on the desk research and reconnaissance survey. The baseline data for various parameters of physical (physiography, geology, seismicity, soil and mineral), ecological (forestry and wildlife), and environmental pollution (air, water, noise, and solid waste) has been documented. The impacts are assessed for various phases of project cycle namely Impacts due to project location, Impacts due to project design, Impacts due to project construction, and Impacts due to project operation. The impacts are categorized as negative, positive or no impacts. The cost of management and monitoring programs are estimated on the basis of mitigation measures suggested for negative impacts and environmental monitoring program during construction and operation. The approach and methodology adopted for the study is presented in Figure 1.1. The standard methodology for the data collection, impact assessment and formulation of management plans is adopted while carrying out the field study and preparing the report. The approved Terms of Reference are kept in mind during the field study. The consultant collected and compiled the environmental baseline data for environmental attributes from primary and secondary sources. The primary sources include site visits, visual inspection, field studies, monitoring and analysis. The secondary sources include the books, reports, maps and documents from various government and non-government organizations on subject matter Environmental Impacts Associated with Airport Projects Major adverse impacts due to the development of airport projects are given as follows and these impacts are discussed briefly in Environmental Impacts Chapter.

LEGAL, POLICY AND INSTITUTIONAL FRAMEWORK The 1972 UN Conference on Human Development at Stockholm influenced the need for a well-developed legal mechanism to conserve resources, protect the environment and ensure the health and well being of the people in India. Over the years, the Government of India has framed several policies and promulgated number of Acts, Rules and Notifications aimed at management and protection of the environment. During last four decades an extensive network of environmental legislation has grown and presently it has a fairly complex body of environmental legislation aimed at ensuring that the development process meets the overall objective of promoting sustainability in the long run. Moreover, at a higher level, the Indian Constitution has also incorporated specific articles to address environmental concerns through the 42nd Constitutional Amendment of As stated in the Constitution of India, it is the duty of the state (Article 48 A) to protect and improve the environment and to safeguard the forests and wildlife of the country. It imposes a duty on every citizen (Article 51 A) to protect and improve the natural environment including forests, lakes, rivers and wildlife. Reference to the environment has also been made in the Directive Principles of State Policy as well as the Fundamental Rights Environmental Policies Several environment policy statements have been formulated in the last few decades as a part of the Government s approach to integrate environmental and developmental aspects of planning. The policies reflect a gradual shift in emphasis from pollution abatement and control to proactive and voluntary approaches for pollution prevention in keeping with global paradigm shifts and trends in environment management. Following are some of the key policies that have been laid down by the Central Government: National Forest Policy, 1988; National Conservation Strategy and Policy Statement on Environment and Development, 1992; Policy Statement on Abatement of Pollution, Despite these policy documents a need for a comprehensive policy statement had been evident for some time in order to infuse a common approach to the various sectoral and cross-sectoral, approaches to environmental management. As a result, a National Environment Policy (NEP, 2006) has been drawn up as a response to our national commitment to a clean environment, mandated in the Constitution in Articles 48 A and 51 A (g), strengthened by judicial interpretation of Article Legal Provisions for Environment related to Infrastructure Projects The proposed project would be governed by various Acts, Rules and regulations set by the Ministry of Environment and Forests (MoEF) at the Central level and other regulatory agencies at the State and local level. Various environmental standards, specifications and guidelines of Central Pollution Control Board (CPCB) and state level agencies will also be applicable. It is important to mention over here that the Central government framed an umbrella law, called the Environment (Protection) Act, 1986 to broadly encompass and regulate an array Chapter - 1 Page 4

255 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand of environmental issues. The overall purpose of EPA was to establish an overall coherent policy and provide a basis for the coordinated work of various government agencies with operational responsibility for the environment and natural resources. The legislation also invests authorities with regulatory powers to address specific issues affecting the environment. The Act also does not allow any person to carry on an industry, operation or process that discharge or emit any environmental pollutants in excess of standards prescribed under specific rules and notifications. The Acts, Rules and Notifications applicable to environmental aspects of the constructional and operational phases of the proposed project are summarized in the Table 1.1 below and briefly described in the following sections.

The guidance manual consists of Terms of reference, manual and questionnaire for preparing EIA studies for Airport projects.the sector specific manual consists of twelve chapters, which correspond to generic structure given as per EIA notification 2006, as amended in Dec The present EIA report for Pithoragarh Airport is prepared as per the EIA guidance manual for Airports International Civil Aviation Organization (ICAO) International Civil Aviation Organization (ICAO), a specialized agency of the United Nations was created in 1944 to promote the safe and orderly development of international civil aviation throughout the world. It sets standards and regulations necessary for aviation safety, security, efficiency and regularity, as well as for aviation environmental protection. The ICAO Council's Committee on Aviation Environmental Protection (CAEP) conducts the majority of ICAO s environmental technical work and has developed a range of Standards to address aircraft noise and local air quality. India being one of the member states of ICAO, implements the resolution on environmental policies and practices adopted by ICAO through Director General of Civil Aviation (DGCA), under Ministry of Civil Aviation, GOI at national level to mitigate the operational impact associated with aviation at airports. ICAO ensures that environmental concerns are strategically integrated into air transport policy by: Improving technical environmental standards on noise and gaseous emissions; Advancing long term technology improvements; Inspecting aerodrome site for issuing aeronautical clearance; Improving the air traffic management and promoting flight safety environment at airports. ICAO agenda is focused on the Committee of Aviation Environmental Protection (CAEP), whose 18 member states make recommendations through five groups: WG1: Reducing Noise (Noise stringency limits engines) WG2: Land use planning and management, operating restrictions and other issues associated with noise such as modeling WG3: Reducing emissions at source (emission limits) WG4: Operational mechanism for reducing aviation emissions; and WG5: Market based options (legal & administrative issues surrounding emissions permit trading, environmental charges and voluntary agreements as a means to limit or reduce emissions) Water (Prevention and Control of Pollution) Act The use of water resources and also the discharge of polluted water (sewerage) are primarily regulated by the Water (Prevention and Control of Pollution) Act, The Water Cess Act, 1977 including Rules 1978 and 1991 provides for levy and collection of Cess on water Chapter - 1 Page 7

The Act assigns functions and powers to the CPCB and SPCBs for prevention and control of water pollution and all related matters. The Environment (Protection) Rules under the EPA also lays down specific standards for quality of water effluents to be discharged into different type of water bodies (sewers, surface water bodies like lakes and rivers, and marine discharge). Additionally, the water supplied to users for drinking shall also conform to the National Drinking Water Standard, IS Table 1.2 summarizes the general standards for discharge of effluent in Inland Surface Water Bodies. To ascertain and categorize the existing water quality for drinking purposes, the results of the analysis of water quality need to be compared with the water quality standards given in Table 1.3.

260 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand Air (Prevention and Control of Pollution) Act The Air (Prevention and Control of Pollution) Act, 1981 (also commonly known as the Air Act) including Rules 1982 and 1983 was enacted to prevent, control and reduce air pollution. According to Section 21 of the Act, no person shall establish or operate any activity, which can cause air pollution without obtaining Consent to Establish (CTE) as per the Air Act. The Act also lays down national ambient air quality standards for common pollutants like PM, Sulphur Dioxide, Oxides of Nitrogen, Carbon monoxide and Lead with the intent of managing air quality for different category of areas (residential/industrial and sensitive). Ambient Air Quality Standards have been notified by the MoEF vide Gazette Notification dated 16 th November 2009, which have been presented as Table 1.4.

Daytime is from 6.00 AM to PM.; 2. Night time shall mean from p.m. to 6.00 AM; 3. Silence zone is an area comprising not less than 100 metres around hospitals, educational institutions, courts, religious places or any other area which is declared as such by the competent authority; 4. Mixed categories of areas may be declared as one of the four above mentioned categories by the competent authority The Environmental Protection Rules (EPR) also lays down equipment specific noise emission standards for DG sets, Air conditioners and Construction Equipment, which would be in use for the project. Specific standards for control of noise from DG sets and measures to be taken for reduction of noise by using acoustic enclosures, acoustic treatment of rooms or exhaust mufflers have also been specified through the Environment (Protection) Second Amendment Rules notified through notification GSR 371 (E) on 17 th May Ambient Noise level standards have been notified by the MoEF vide Gazette Notification dated 26 th December 1989 and also in the Schedule III of the Environmental (Protection) Rules It is based on the A weighted equivalent noise level (L eq ) Solid Waste Rules Once project is completed, the management of the proposed project would be responsible for collection and handling of domestic solid waste (before it is transferred in bulk from a collection point to the municipal waste disposal site) as per the provisions of the Municipal Solid Waste (Management and Handling) Rules, The Hazardous Waste (Management, Handling and Transboundary Movement) Rules, 2008 require facilities to classify wastes into categories, manage them as per the prescribed guidelines and obtain prior authorization from the SPCB for handling, treatment, storage and disposal of Hazardous Wastes INSTITUTIONAL FRAMEWORK Whereas the legislative branch of the government (Parliament) is responsible for the enactment of environmental law and the judiciary for its enforcement in the case of transgression, it is the function of the executive branch (ministries, regional and local authorities) to determine policies and administer environmental law in actual practice. Also, since an environmental dimension has now become a part of all economic activities, an effective mechanism of coordination and control is the responsibility of the central environmental agency so that environmental policies can be translated into action. The Government of India took a major step in 1972 when it constituted the National Committee on Environmental Planning and Coordination (NCEPC). Later in 1980, the Government of India established a new Department of Environment on the recommendation of a committee constituted by the Indian Parliament. The Central and State Pollution Control Boards were set up and entrusted with the task of air and water pollution control in Chapter - 1 Page 11

262 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand Ministry of Environment and Forests Developmental project proponents are required to submit Environmental Impact Statements/Assessments to establish that adequate pollution control measures would be provided so that pollutants discharged into the environment would not exceed permissible levels. The MoEF appraises these statements/ assessments and approves the project from the environmental angle on the basis of final report which incorporates public hearing outcomes. The respective regional office of MoEF monitors the work during construction and operation to safeguard the environment as per the recommendations made by MoEF Central and State Pollution Control Boards The Central Pollution Control Board is directly responsible for pollution control throughout the national territory. In addition to the control of air, noise and water pollution it is also responsible to ensure effective control on disposal of hazardous wastes and storage and handling of hazardous chemicals and substances. Additionally, with the enactment of air and water pollution laws, states have set-up their own Pollution Control Boards (SPCBs) to monitor industrial emissions and effluents and to approve the operation of new industries after careful scrutiny. The functions of the SPCBs include: The planning of comprehensive state programs for the prevention and control of air and water pollution and to ensure the implementation thereof; Inspection of control equipment, industrial plants, etc. Different emission standards may be laid down for different industrial plants, having the quantity and composition of emissions into the atmosphere from such plants and quantifying the general pollution levels in the area; advising the State Government on citing of new polluting industry FORMAT OF THE EIA REPORT Chapter-1 of the report is on Introduction. The legal/ policy frameworks along with environmental standard are summarized in this chapter. In Chapter - 2, a concise documentation is given on the proposed project activities and facilities including site selection, project features, construction schedule and cost estimates.

PROJECT LOCATION CHAPTER - II PROJECT DESCRIPTION The proposed development will be at the existing Naini-Saini airport; located in the Pithoragarh district of Uttarakhand State. The airport is situated about 4 km from the Pithoragarh town. The town is approachable by road through Almora, Nainital, and Kathgodam. Kathgodam railway station is the nearest rail head from Pithoragarh with a distance of 180 km. Dehradun, the state capital is about 460 km away by road and 50 minutes journey by air. The district forms the north-eastern part of the Kumaon Division and lies between Lat. 29 o 27 N. and 30 o 49 N. and Long. 79 o 50 E. and 81 o 3 E., the length from north to south being about 151 Km, and the breadth from east to west being about 119 Km. It is bounded by China on the north, Nepal on the east, district Champawat & Almora on the south and the districts Bageswar and Chamoli on the west. The location of the project area is shown in Figure PURPOSE OF THE PROJECT The existing airport occupies an area of about 28 hectares and is situated at about 04 km away from Pithoragarh on Pithoragarh Dharchula State Highway. The airport is located near villages Naini, Saini, in Kumaon Hillls of Uttarakhand. The existing airport was constructed during 1991 for the administrative use. The airport is owned by the State Government of Uttarakhand. At present, there are no commercial operations/activities at this airport since the runway and existing infrastructure facilities are at poor condition. State Government of Uttarakhand decided to develop the airport for commercial activities since the project is the gateway for tourism development in Pithoragarh District. Also the development of existing airport at Pithoragarh is necessary for emergency situations since the district is having the international boundaries with China and Nepal EXISTING FACILITIES The present Naini-Saini Airport of Pithoragarh has the following facilities: Airport was planned for operations of Dornier type aircraft Runway m X 20m Apron - 50m X 30m Taxiway - 50m X 15m Terminal Building - 2 Floors RCC structure without any doors / windows ATC - Above the terminal building Fire station - Abandoned Residential Quarters - Abandoned Car Park Facility - for 20 no.s Fire rescue facilities, airfield lighting, navigational/ communication aids power supply and water supply were not available at the existing airport.

Brief description of various components considered for the proposed project as per DPR is given below: Aircraft: Aircraft characteristics have an important role in airport planning. The aircraft characteristics will determine the runway length and width, the minimum separation distance between runways and taxiways, the geometric of pavements, and the pavement strength. As per objectives, the type of aircraft intended for operations is ATR-42 aircraft. The technical characteristics of ATR-42 aircraft are given in Table 2.1. Aircraft ATR ATR Seating Capacity TABLE 2.1 AIRCRAFT TECHNICAL CHARACTERISTICS Aerodrome Takeoff Field Landing Wing Ref. Code Length (m) Field length span (m) Length (m) MTOW (kg) 48 2C C Aerodrome Elevation and Runway Orientation: The co-ordinates of the Airport at Pithoragarh are N Latitude and E Longitude and the elevation is m above MSL. The orientation of existing runway is Aerodrome Reference Code: The aerodrome reference code derived based on the dimensions of design aircraft as per provisions of ICAO (Annexure 14) is 2C and is a key planning parameter. Future expansion of the airport is constrained due to hilly terrain all round the airport and non availability of land. The presence of cluster of hills in the vicinity at 14 end (Approach 32) constitute major obstacle, making the runway unfit for operations at this end. For the purpose of planning the facilities, the proposed runway is considered as Non-Instrument code 2C for ATR-42 day VFR operations. Terminal Building: The existing terminal building needs to be demolished, in order to have safe operations and to accommodate the expansion of the apron. The new terminal building is to cater 20 incoming and 20 outgoing passengers, totaling to 40 passengers. As per area norms prescribed by the Ministry of Civil Aviation in the Report of the Inter-Ministerial Group of September 2008, for peak hour passenger up to 100, an area of 12sqm/php is recommended for Category C level of service. The minimum area requirement as per this thumb rule works out to 480 sqm. However after making provisions for other amenities, such as offices & passenger amenities, an area of 500 sqm is proposed for the terminal building to meet the minimum requirements for 20 incoming and 20 outgoing peak hour passengers. Chapter - 2 Page 16

268 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand The proposed Terminal is designed on a single level for maximum comfort of passengers. The interconnectivity of spaces/processes ensures that there is an efficient & seamless flow between the city side and airside elements. Also since the project area is in a semi hilly & sloping terrain, therefore the entry/exit level of the passenger terminal building has been placed 2M below the apron level so as to economise on earthwork costs and avoid the building becoming an obstruction in the transition surface of OLS. The apron is connected to the departure & arrival gates by gently sloping ramps. Terminal building plan of the proposed project area is shown in Figure 2.4. Peak Hour Passenger (PHP) Traffic: The domestic Peak Hour Passenger rate of 20 departures + 20 arrivals is considered for the design. Ease of Baggage Handling Activities: Baggage handling is a significant element of passenger processing & is of major importance to a smooth airline operation at the airport. The system must be able to sort large numbers of bags quickly & with a high degree of performance reliability. Also the system should not conflict with the flow of passengers, cargo, crews or vehicles. In the proposed terminal, the baggage is handled at independent locations towards the airside, easily accessible so as to provide for ease in activities. Security Systems: All sensitive spaces in the terminal building will be closely monitored through surveillance system. Air Conditioning & Fire Fighting Provisions: Keeping in view of the climate at Pithoragarh, the terminal building is proposed to be non air conditioned. For external fire fighting, a fire main ring is proposed around the building with fire hydrant outlets at regular intervals, backed up by a static tank & continuous pressurized supply. All the major buildings will have fire detection & alarm system installed and all the applicable fire norms will be adhered to. Parking Provisions: Adequate parking provisions have been made on the city side for the passengers as per the building norms. A total of 20 car parks have been provided for parking. The area has no provisions for future expansion. No separate car parking for staff/vip has been provided. Landscaping & Horticulture: Both air side and city side has been provided green touch by incorporating adequate green spaces. On the city side the vehicular parking is designed to merge in the green surroundings & the airside also has a green buffer space separating the terminal building & the apron. Runway Dimensions: Due to the limited length of land available, it is proposed to provide a runway of length 1510 m which will be sufficient for operations of ATR 42 to meet the destinations within a range of 350 km. This is the maximum length of runway that can be provided within the available land leaving clearances for the boundary wall in the approach. It is therefore proposed to extend the existing runway by m on 14 end and 38.7 m on 32 ends thus making the total extension to 210 m to meet the runway length requirement. Future extension of runway for operations of aircraft like ATR 72 is not feasible as the land is not available at both ends. The width of runway for aerodrome reference code 2C is 30m. No shoulders are proposed, as it is not mandatory to provide shoulders for category 2C runway. Chapter - 2 Page 18

270 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand Runway Strip: Graded runway strip of width 80 m (40m on either side of centerline of the runway) is proposed in accordance with ICAO stipulation for aerodrome reference code 2, non-instrument runway. However, if the airport is to be upgraded to instrument runway Code 2 or Code 3 non instrument runway in future, the requirement of runway strip width would be 150m. (75 m on either side of centre line of runway). In that event, the apron and proposed terminal facilities will form obstruction. Taxiways: The existing link taxiway facilitates direct exit from the runway at The width of existing taxiway is 15m and is in conformity with ICAO recommendation for ATR 42 aircraft. 5m wide shoulders on either side of the taxiway are proposed for the taxiway so that the overall width meets the requirement of 25 m. Terminal Apron: Existing apron is located at a lateral distance of 60 m from the runway centre line of runway. This separation distance is inadequate for Code 2C, non instrument runway. The size of the existing apron is 50 m x 30 m. This is also inadequate for parking of 2 ATR -42 aircraft. The wheel path of the aircraft was analyzed and it was found that for smooth parking of 2 ATR 42 aircrafts, an apron of size 90m x 60m is required. Due to unavailability of land for expansion of the terminal facilities, expansion of the aircraft parking apron is proposed in such a way that the aircraft parking positions will not constitute obstruction in the transition. Isolation Bay: Due to non availability of space in the airport, isolation bay is not provided. The proposed airport being a low activity airport, in the event of an emergency, the runway ends are to be used as isolation bay with airport operations remaining closed. Exemption to this effect is required to be obtained from DGCA/BCAS. ATC Tower and Services: A fully functional low activity ATC Tower with a tower cab floor area of 36 sqm is proposed. To meet the minimum line of sight and grade intersection angle of 35, the height of the tower is recommended as 25m above GL with an eye level of more than 15.0 m above the average runway level, which will facilitate un-obstructed view of operational areas as well as surrounding air space. The Tower will provide Aerodrome Control and Flight Information Services. The office space available in the Ground and First Floors are proposed to accommodate Met office and Technical Block. Fire Station (Crash Fire Rescue Services): Category 4 level of protection is required to be provided to meet the requirement of design aircraft. For level of protection 4, minimum 1 No. of Crash Fire Tender is required to be provided. A fully equipped Ambulance shall also support the Crash Fire Rescue Services. A fire station of 225 sqm is proposed to house the CFT, Ambulance and a Jeep. Aircraft Hangar: No aircraft hangar is proposed as there is no space available for the same. Electric Sub Station, Pump House and UG Sump: It is proposed that a compact and packaged type sub-station of capacity 500 KVA installed in an area of 225 sqm as shown in the development plan. Power supply from state electricity board will be drawn up to the substation of Airport. An Underground Water Tank & a pump house will also be provided near parking area as shown in the development plan. Staff Quarters: The existing staff quarters at the airport are proposed to be demolished and due to unavailability of land at the airport, no staff quarters are proposed. It is seen that as Chapter - 2 Page 20

271 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand the airport is situated near to the Pithoragarh city, the staff can reside in city and can commute for work at the airport. Approach Road: A single lane bitumen surfaced access road of 5 m width connects the terminal area with city main road. This road needs to be widened to at least 2 lane standards. As the road outside the airport is under the state administration, the district authorities may be asked to widen this road to a 2 land road. Internal & Perimeter Road: Internal roads facilitating connections between the various component facilities of the proposed airports are included in the development plan. A perimeter track of 3.75m width is proposed in the operational area. Drainage: RCC Open drain is proposed to be provided along the edge of the strip on either side of runway and taxiways for disposal of the storm water through natural slopes. Rectangular drains with perforated slabs are proposed in terminal building area. Two existing culverts across the runway are proposed to be dismantled and reconstructed to make it suitable to receive the ATR-42 loads. The other box culvert will be replaced with a pipe culvert. Boundary Wall/ Retaining wall: It has been observed that the runway area is lower than the adjoining land of farmers on the Northern side. It is proposed to construct a RCC retaining wall of varying height, all along the boundary of airstrip on Northern side as per the proposed plan. The boundary wall will be constructed over retaining wall with a height of 3m above the ground level. In the areas where the retaining wall is not required, a 2.4 m high boundary wall with 0.6 m barbed wired fencing is proposed to be constructed to meet the security requirements. 2.4 m high Chain link fence is proposed to cordon the operational area from the land side. Runway Lighting: Runway, apron, taxiway and threshold edge lighting are being proposed. Power Supply requirement: With the proposed development works, the power requirement for the airport works to 500 KVA. It is proposed to provide packaged units of sub-station. The packaged sub-station will be housed in a shed of 225 sq.m area. The requirement was discussed with State Electricity Board and they have informed that power is available and will be provided for the airport. In addition to the electricity from State Government; 3 DG sets with a capacity 500 KVA each are proposed for backup as part of the Airport development PROJECT TIMEFRAME AND MANPOWER REQUIREMENT The proposed expansion of Naini-Saini Airport at Pithoragarh is expected to be completed in a period of 18 months after award of work to contractor. Manpower will be required during construction and operation of the proposed airport expansion. During construction, requirement will be temporary in nature while during operation it will be permanent. The basic requirement of manpower for operation of the Airport will be categorised as Technical and Non-Technical. Technical manpower should cover all operation and maintenance functions. Non-Technical manpower should cover the functions of stores, housekeeping and accounts etc. The manpower required for Airport is 100 during construction and 20 during operation phase of the project.

The probable date of commencement of the elevation of the Himalayas is about the close of the Mesozoic period. According to geological formations of the district, it may be divided into four broad belts, viz., (1) the innermost Siwalik hill ranges, (2) the lesser and middle Himalayas, (3) the inner Himalayas and (4) the thin belt bordering the Tibetan Himalayas, roughly tending east-south-east. Geological map of Pithoragarh district is shown in Figure 3.1. FIGURE 3.1 GEOLOGICAL MAP OF PITHORAGARH DISTRICT The belt of the innermost hill ranges of the Siwalik group lies in the southern part of the district. In the rock formations here sandstones alternate with clayey shales. The sandstones are dirty, friable and micaceous and are, therefore, unsuitable for the building, ballast and industry. The second belt, comprising the ranges of the lesser and middle Himalayas, extend north of the Siwalik group to Dharchula. It contains sedimentary and low to medium grade metamorphic rocks such as limestone, slate, quartzite, phyllite and mica-garnet schist. Mineralization of copper, magnesite, soap-stone, etc., is known to occur in this belt. Chapter 3 Page 25

276 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand The third belt, containing higher ranges of the inner Himalayas, is wholly composed of crystalline metamorphic rocks such as mica and garnet schists, kyanite and sillimanite schists, gneisses, granulites and quartzites. This belt is very little known geologically. The belt extends from near Dharchula to Garbyang. The fourth belt, bordering the Tibetan Himalayas has an average width of about 7 km. It contains marine sedimentary rocks such as quartzites, fossiliferous limestones and shale. The project area falls in lesser Himalayas (metamorphism mostly reversed) and the geologic period of upper proterozoic. The minerals available in the Pithoragarh district are Copper, Magnesite, Soapstone, Arsenic, Sulpher, Kyanite, Graphite, Slate and Limestone Soils Soils consist of mechanical mixtures and chemical compounds of the materials found on the surface of the earth. They contain both inorganic and organic materials. The physical and chemical characters of the parent rock, physiography, altitude, climatic condition and plants and animals of the surrounding region influence the process of soil formation. Different soils available in the district are skeletal soils, mountainous, sub-mountainous and snow fed soils etc. Soil map showing location of project area is shown in Figure 3.2. The soils within the 10 km radius from airport are sub mountainous soils. These soils are rich in humus content and generally dark brown or black in colour.

WATER ENVIRONMENT Water environment consists of water resources and its quality. Its study is important from the point of view to assess the sufficiency of water resources for needs of the project in its various stages and the impact of the project on water environment. In the proposed project area, surface and ground water quality have been tested to evaluate its suitability for the intended purpose Water Resources of the District Most of the water needs in the project area are met from ground water sources. Ground water comes out at certain places on surface in the form of springs, most of which are perennial in nature as observed at site. During field visits in the project area, it is observed that hand pumps are being used for drinking purpose. Surface Water: Surface water is available in the form of rivers and streams. The district is abundant in rivers most of which are originated within the district. These rivers are geographically grouped under the rivers of Ganga System. These rivers are Girthi, Keogad, Kali, Gori, Dhauli, Kutiyangti, Sarju, and Ram Ganga. Chapter 3 Page 34

285 EIA studies for expansion and strengthening of runway and up gradation of associated operational infrastructure and terminal facilities at Naini Saini Airport, Pithoragarh in Uttarakhand Ground Water: Ground water is available in the form of springs and hand pumps. The occurrence of springs is a common phenomenon in the district. The moving ground water surfaces out as springs through Joints/Fractures etc. The topographic breaks are the favorable location for spring formation. The springs have been developed for drinking and irrigation in most places of the district Water Quality of the Project Area In order to assess the baseline water quality status of the study area, four samples were collected in the project area, which includes one surface water sample and three bore well (ground water) samples. The sample locations are shown in Figure 3.3 and description of Soil quality monitoring locations are given in Table 3.6. The samples were analyzed for physical and chemical constituents for the purpose of domestic and irrigation use. The results of water analysis are compared with CPHEEO manual for Drinking Water Specifications. The results of analysis are presented in Table 3.7. The analysis of water samples indicates that all the parameters are within the permissible limits except alkalinity for sample locations 1, 3 and 4. Dissolved Solids concentration exceeded permissible limits at sample 3. Water from these sources should be treated before using it for drinking purposes. Station.

AMBIENT ENVIRONMENT The ambient environment is responsible for the health of human beings, animals, wildlife and vegetation. The ambient environment covers climate, atmospheric pollution and noise pollution. All air pollutants emitted by point and non-point sources are transported, dispersed or concentrated by meteorological and topographical conditions. The meteorological parameters regulate the transport and diffusion of pollutants into the atmosphere. In order to assess the impact on existing ambient environment due to the project, it is necessary to have baseline status of ambient environmental parameters. Meteorological data on rainfall, wind, humidity, and temperature was collected from secondary sources. The ambient environmental status existing in the project area is discussed in different paragraphs as under Meteorology The elevation of the district ranges from 500 m above MSL in the valleys to over 7000 m in the snow bound Himalayas. The climate largely depends on altitude and varies according to aspect and elevation. Most part of the district is falls in the southern slopes of the Himalayas. The entire district can be grouped into the following climatic zones as given in Table 3.8. Chapter 3 Page 35

The ambient air quality within the project study area (10 km radius) is considered for the analysis. The sources of air pollution during the construction phase would be due to the site clearance & preparation activities, material handling activities, emissions from construction equipment & vehicular movement, and operation of diesel generators. Air quality monitoring was carried out at 4 locations within/ nearby vicinity of the proposed project, for twice a week for one season. The sample locations are shown in Figure 3.3 and description of Soil quality monitoring locations are given in Table Seven major air pollutants viz. particulate matter (PM 10 & PM 2.5 ), Sulphur Dioxide (SO 2 ), Oxides of Nitrogen (NOx), Carbon Monoxide (CO), Lead (Pb) and Hydro Carbons (HC) representing the air quality was monitored. Air quality monitoring was carried out by collecting 24 hourly samples for 2 days in a week in one season at 4 locations. Results of the monitoring are tabulated in Table The air quality monitoring results indicate that all parameters were noted within the limits for residential areas except at Naini village where PM10 and PM2.5 are exceeded to permissible limit for first 24 hrs monitoring out of 48 hrs continuous monitoring.

291 EIA studies for expansion and strengthening of runway and up gradation of associated operational infrastructure and terminal facilities at Naini Saini Airport, Pithoragarh in Uttarakhand Noise Environment Noise beyond tolerance limit can lead to effects such as noise induced hearing loss and annoyance depending upon the loudness of noise levels. The environmental impacts of noise from the proposed construction activity and traffic movement are required to be assessed on factors like potential damage to hearings, psychological responses and annoyances. Noise is of concern during construction phase of the project. The impacts of noise sources on surrounding community depend upon: Characteristics of noise sources (instantaneous, intermittent or continuous in nature). It can be observed that steady noise is not as annoying as one, which is continuously varying in loudness. Time of day at which noise occurs, for example high noise levels at night in residential areas are not acceptable because of sleep disturbance. Location of noise source, with respect to noise sensitive land use, which determines the loudness and period of exposure. Noise level survey was conducted at the project site with an objective to establish the baseline noise levels and assess the impacts of the noise expected due to the proposed development. Noise levels were recorded on hourly basis for 24 hours in order to have an assessment of the Day and Night time noise levels. The sample locations are shown in Figure 3.3 and description of Soil quality monitoring locations are given in Table The average noise levels so obtained are summarized in Table The ambient noise quality criteria laid down by CPCB has been given in Table 1.5 of Chapter - 1. From the table, Leq for day and night at all locations exceeds the National Ambient Noise Standards for Residential Zone. The main source of noise in the project area is the traffic movement on the road. TABLE 3.13 DESCRIPTION OF NOISE QUALITY MONITORING LOCATIONS Station.

ECOLOGICAL ENVIRONMENT An ecological study of the ecosystem is essential to understand the impact due to project development activities on the existing flora and fauna of the area. The present study was undertaken to predict changes as a result of project activities and to suggest measures for maintaining the conditions to the maximum possible extent. This section describes the ecology of the area based on field study and information compiled from secondary data available for the study/project area Forest Uttarakhand state is rich in forest resources. Due to topographical variation and diverse climatic conditions a variety of forests are found in the state. Forest map of Pithoragarh district is shown in Figure Reserved Forest Area blocks found around the proposed project area in Pithoragarh district are given in Table Nearest block is Saurlekh block at an aerial distance of about 1.75 km from project area Flora and Fauna TABLE 3.15 RESERVED FOREST AREA BLOCKS S. No Name of the Block Area in Ha 1. Saurlekh Dhaj Chandag Kalapanigarh Thalkedhar Gurna Taking into consideration the differences in the altitudes and the climatic conditions which exists in the district, its flora may be divided into four main divisions namely the sal forest, chir forests, oak forests and the coniferous forests. There is no forest land within the proposed airport area. Prominent trees present in the project area are chir, peepal pahari, meil, kharikya and naspate. Common fauna found in the project area are cattle, buffaloes, sheep, and goat. No rare and endangered species are found within the project area National Parks and Wildlife Sanctuaries The proposed project area for the airport and in its neighborhood within 10 km radius has no wild life sanctuary or national park EPILOGUE Based on the project particulars (Chapter - 2) and environmental baseline data of project area (Chapter - 3), an attempt has been made to critically assess the negative and positive impacts due to the project in various phases of project cycle. These positive and negative impacts are discussed in Chapter - 4. To mitigate the negative impacts, an Environmental Management Plan is prepared and kept under Chapter - 6. And Chapter - 7 describes Environmental monitoring plan while Chapter - 8 describes Environmental Costs. Chapter 3 Page 42

294 EIA studies for expansion and strengthening of runway and up gradation of associated operational infrastructure and terminal facilities at Naini Saini Airport, Pithoragarh in Uttarakhand CHAPTER - IV IMPACT ANALYSIS AND MITIGATION MEASURES 4.1. GENERAL The objective of environmental impact assessment is to ensure that development should proceed hand-in-hand with ecological preservation so as to achieve sustained growth. In pursuance of the global goals of nature conservation and protection of environment, state governments have initiated plans, schemes and actions to implement various legislation, the latest being the Environment (Protection) Act, In September 2006, MoEF has issued a notification on EIA for different projects. The notification lists 8 types of projects or activities, which need environmental clearance from EAC or SEAC; proposed Airport falls in schedule 7a in the list. The pollutants generated at the proposed project premises during construction and operation phases are solid, liquid and gaseous in nature. Pollutants may be generated continuously, periodically or accidentally. This section identifies and appraises the negative as well as positive impacts on various aspects of the environment likely to result from the proposed development. The impacts on the above environmental components have been further assessed during various phases of project cycle namely project location, construction and operation. The potential environmental impacts anticipated (positive and negative) during various phases of the project cycles for the proposed project is dealt in this chapter, while the mitigation measures are elaborated in Chapter IMPACT IDENTIFICATION The environmental impact assessment process begins by identifying the development and operational activities resulting from the proposed project. Potential impacts due to the proposed Airport on the environment in different phases of the project cycle namely location, construction and operation have been identified. The type and magnitude of impacts however, depend on the specific attributes of the given environment. As far as possible, attempts have been made to quantitatively predict the impacts due to the project. For non-quantitative impacts, qualitative assessment has been made. Potential impacts on environmental components due to the proposed project activities have been summarized in Table 4.1. The impacts due to project location are generally irreversible and could be mitigated through environmental enhancement measures. Impacts related to construction are normally short term, which can be set-off by observing a simple set of precautionary measures ENVIRONMENTAL IMPACTS This section identifies and appraises various negative impacts likely to result from the proposed development as reported under Chapter - 2, on environmental baseline conditions as reported in Chapter - 3.

296 EIA studies for expansion and strengthening of runway and up gradation of associated operational infrastructure and terminal facilities at Naini Saini Airport, Pithoragarh in Uttarakhand Negative impacts likely to result from the proposed development on land, water, air, noise, ecology and socio-economic have been listed under various phases of project cycle under the following headings: Impacts due to project location, Impacts due to construction works, and Impacts due to project operation 4.4. IMPACTS DUE TO PROJECT LOCATION The environmental impacts, which may take place due to location of the project, are discussed briefly as under: Displacement of People Loss of land / Change in land use, Loss of Infrastructure, Encroachment into forest/ Wildlife Habitat Corridor, Loss of historical, cultural and religious monuments/structures, and Risk due to earthquake Displacement of People The proposed area is located 4 km away from Pithoragarh City. Naini and Saini villages are located near the project site at a distance of about 100 m from project site. No displacement of people due to the proposed project is anticipated; however one school exists near to the boundary of the project which needs to be displaced or relocated. Management plan for shifting/relocation of the school is given in Chapter - 5. The major land use category is vegetation Loss of land / Change in land use The proposed construction of infrastructure facilities and strengthening of runway are planned within the existing airport premises. No land acquisition is involved for the proposed project, since the required land is in possession of USIDC, and free of any kind of encumbrance. There will be no displacement of people due to acquisition of land/property or any other activity related to the project, on-site or off-site. The proposed development would change about 28 ha area (the area requirement for the project) of vacant land into built up area, thus bringing about change in the existing land use of the project study area. The required land is, however, within the area earmarked for the airport. The proposed development will enhance the aesthetics due to development of a modern building and the surrounding horticulture/landscaping Loss of Infrastructure Infrastructure comprises of schools, hospitals, establishments, communication, post offices, community resources, etc. One school exists near to the boundary wall of the airport which needs to be relocated. A bituminous road connecting Naini-Saini village is passing through Chapter 4 Page 46

297 EIA studies for expansion and strengthening of runway and up gradation of associated operational infrastructure and terminal facilities at Naini Saini Airport, Pithoragarh in Uttarakhand the proposed extension of runway area at 32 end. This road is required to be closed. Management plan for shifting/relocation of the school and road is given in Chapter Encroachment into Forest/ Wildlife Habitat Corridor Loss of trees or shrubs is not anticipated due to the proposed project activities. The project area does not encroach into any Forest Land or Wildlife Habitat Corridor Land. The proposed land is already in possession with USIDC Loss of Historical, Cultural and Religious Monuments/Structures No historical, religious or cultural monuments will be lost due to the project location or its activities Risk due to Earthquakes The airport area falls in Zone V of the seismic zoning classification of India. Though the project area is not reported to have originated any earthquake, but has experienced shocks / tremors due to earthquakes occurring in the neighboring region. The construction of airport will require use of appropriate design technology so that they can withstand the seismic forces. Necessary factor of safety and appropriate coefficient would be incorporated in designing the structures under the worst combination of forces. The impact of earthquake cannot be predicted, only precautionary measures would reduce the impact during construction and operation IMPACTS DUE TO PROJECT CONSTRUCTION Although environmental impacts related to construction works are mostly temporary in nature, this does not mean that these should be given less importance. In order to mitigate the adverse impact due to project construction, the appropriate measures have been considered. The most likely impact included in the work plan and estimates covered to construction works are as under: Impact on Soil Quality/Erosion, Health Risks and Cultural Effects, Water Use and Quality, Air Pollution, Noise Pollution, and Solid Waste Impact on Soil Quality/Erosion The topsoil shall be disturbed during the construction stage due to excavation and movement of vehicles and equipment. Exposure of loose soil to rain water will increase turbidity in the run-off; however, this impact is limited to the possibility of excavated surfaces prevailing in the rainy season. On completion of the construction activity, all the unpaved area shall be covered with vegetation, which will reduce soil erosion. As such, the Chapter 4 Page 47

298 EIA studies for expansion and strengthening of runway and up gradation of associated operational infrastructure and terminal facilities at Naini Saini Airport, Pithoragarh in Uttarakhand impact on soil quality is short term in nature, which can be avoided by applying good construction practices Health Risks and Cultural Effects Health risk during construction phase, include disease hazards due to lack of sanitation (water supply and human waste disposal), vector borne diseases and hazards due to local carriers. About 100 people are expected to be working during peak construction period at project site. Therefore, mitigation measures must include proper sanitation, health care and human waste disposal facilities which shall be provided for all these people. Sanitation facilities are included in the project estimate to take care of cost towards human waste disposal facility during construction Water Use and Quality The project implementation would involve various construction activities. The construction of various project activities would require water. Water demand during construction phase would be for construction activities and domestic use. About 100 workers will be working during peak construction activity. Though there will be no provision of labour camps at construction site, however, provision of adequate drinking water and toilet facilities will be made. Drinking water requirement during construction period is assessed to about 500 liters per day (by assuming 5 lit/capita/day). Requirement of water for water closets and urinals for the 40lit/capita/day works out to be 4000 liters/day. It is estimated that the proposed construction works will consume about 50,000 lit/day. Thus, the water quantity of 54,500 lit/day will be required during the proposed construction period, which shall be arranged by the contractor from nearby surface water source. The breakup of water consumption during construction of the airport is shown in Table 4.2. TABLE 4.2 WATER REQUIREMENT DURING CONSTRUCTION STAGE S. No Description No. of Workers Water Requirement lpcd Total Water Requirement Lit/day 1. Drinking Water Water for water closets and urinals Water required during peak construction activity Total Water Requirement 54,500 Remarks IS Code Contaminations of groundwater due to the spilling of construction materials like oils/greases and paints are not anticipated due to limited construction activity. Inadequate sanitary facilities and poor drainage may lead to spreading of waste water on ground and finding its way to contaminate ground water. Waste, whether solid or liquid, generated from construction activities should be transported at regular intervals to the disposal sites to avoid the contamination of ground water. Wastewater generation during construction from workers toilets is assessed to about 3.6 KL every day (By considering 90% of water required for workers toilets converts to waste water). Proper treatment is required for the sewage generated from the construction site. Chapter 4 Page 48

299 EIA studies for expansion and strengthening of runway and up gradation of associated operational infrastructure and terminal facilities at Naini Saini Airport, Pithoragarh in Uttarakhand Air Pollution Emissions to the atmosphere from construction sites include particulates (that is dust, motor vehicle emissions and smoke) and odour. Such emissions can have adverse off-site impacts if they are not properly managed or controlled. Emissions can occur from any of the following activities: Clearing of land and related excavation and compaction activities. Operation of heavy machinery and related equipment for earthmoving and construction purposes (excavators, bulldozers, etc.) and the engines associated with such machines. Erection of structures using steel, concrete, brick, glass, timber, and other materials. Mechanical activities including grinding, hammering, drilling, grit blasting and demolition. Metal joining and finishing including welding, brazing, soldering and other techniques. Generation of solid wastes and debris, their stockpiling and transfer through chutes and loading onto trucks or into skips. Transport of building materials and supplies onto the site, transport of wastes off site. Movement of vehicles along roadways and paths, in and out of the site and within the site, together with any establishment and maintenance of the roadways (e.g. grading). Application of surface coatings and finishes using paints and adhesives Sources of odour can be Smoke (from engines and motors), Surface finishing (e.g. spray painting), use of resins, adhesives, caulking compounds, sealants, silicones, etc. and carborundum odours from grinding, cutting and sanding operations. In construction projects, air pollution occurs mainly due to fugitive emissions/dust generation from various construction activities. Fugitive emissions from various construction machinery added with dust generated by movement of construction vehicles would be the main source of air pollution during construction. A list of major construction equipment is given at Table 4.3. TABLE 4.3 MAJOR CONSTRUCTION EQUIPMENT S No. Type of Machinery 1. Air Compressor 2. Dozer 3. Front End Loader 4. Motor Grader 5. Paver 6.

300 EIA studies for expansion and strengthening of runway and up gradation of associated operational infrastructure and terminal facilities at Naini Saini Airport, Pithoragarh in Uttarakhand Background concentration of air pollutants, as reported in Chapter - 3, is quite low and within the permissible limit. The increase in concentration of air pollutants during construction would be of temporary nature. Transportation of construction material and muck shall emit pollutants during construction phase. The predictions of emissions during transportation of material are presented in Table 4.4. For calculation purpose it is assumed that the construction materials shall be transported for a period of 18 months. TABLE 4.4 POLLUTION EMISSION RATE DURING CONSTRUCTION S. No PARAMETER EMISSION VALUE µg/m 3 1. PM CO VOC NOx SOx A short-term reduction in local ambient air quality would occur during construction phase. The main construction activity at the airport will be the pavement construction for which the concrete will be brought to site from ready mix concrete plant. Impacts associated with pollutant emissions during construction are expected to be of short term, thus resulting in a low impact on long-term air quality and visibility Noise Pollution The main source of noise is construction machinery / equipments, haulage of construction material, equipment and DG sets. The DG sets should adhere to the CPCB standards during construction stage. Vehicle noise comes from the engine, transmission, exhaust, and suspension, and is greatest during acceleration, on upgrades, during engine braking, on rough roads, and in stop-and-go traffic conditions. Poor vehicle maintenance is a contributing factor to this noise source. Frictional noise from the contact between tires and pavement contributes significantly to overall traffic noise. However, the magnitude of impact will depend upon the type and nature of machinery, time schedule of operation, construction methods and management practices followed during the activities. Though the effect of noise would be insignificant during daytime, the few residential areas located in the near vicinity of the construction site may experience increased ambient noise levels. However, these impacts would be temporary in nature. Table 4.5 shows typical energy equivalent noise levels at construction site.

301 EIA studies for expansion and strengthening of runway and up gradation of associated operational infrastructure and terminal facilities at Naini Saini Airport, Pithoragarh in Uttarakhand As seen from the above table, construction activities are expected to produce noise levels at source in the range of db (A), which will decrease with increase in distance. For an approximate estimation of dispersion of noise in the surroundings form the source point a standard mathematical model used is as follows: Noise (receptor) = Noise (source) - 20Log[distance (receptor) or distance (source) ] For modeling purposes, flat terrain is considered and environmental attenuation factors are not considered so as to formulate the worst-case scenario. The noise levels predicted by logarithmic equation up to a receptor location of 2 km are presented in Figure FIGURE 4.1 IMPACT ON RECEPTOR DUE TO NOISE GENERATED DURING CONSTRUCTION PHASE Noise level db(a) Series The construction works will be carried out during the daytime. The impact of noise produced during the construction will, however, be limited to a distance of about 75 meters at which, as seen from the figure, the noise level of various equipment will come down below 55 db (A). It could therefore be concluded that the construction activities would not have a significant impact on existing environment out of 75m from the construction place. Due to the high noise levels of construction machinery, the personnel operating the machines and the workers stationed close to the machines are prone to exposure of high levels of noise Impact due to Solid Waste Disposal 1000 Distance from source (m) Inorganic solid waste generated during the construction phase like waste concrete, and mortar, left over aggregate and debris etc. shall be recycled for use in the base layers of paved area i.e. parking pavement and in road construction. Workers camps are not allowed at site. However, the workers during working hours along with other supervisory staff are likely to generate about 20 kg of municipal waste every day, which need be disposed properly. Pollution risks may also arise from accidental leakage and spillage of oil or fuel, which may contaminate the soil IMPACTS DUE TO PROJECT OPERATION The impacts due to project operation shall be long term and can be both positive and negative in nature. The negative impacts could be; Chapter 4 Page 51

302 EIA studies for expansion and strengthening of runway and up gradation of associated operational infrastructure and terminal facilities at Naini Saini Airport, Pithoragarh in Uttarakhand Air Pollution, Noise Pollution, Water Environment, and Impact due to Solid Waste Disposal Air Pollution In airport projects, air pollution occurs mainly due to fugitive emissions/dust generation from aircraft and vehicular emissions. During operation phase of the airport, the source of air pollution will be aircrafts operation and vehicular pollution due to passenger cars. A car parking of 20 cars has been proposed for the airport, in addition it is assumed 20 cars (taxis) have been dropping the passengers at airport. Pollution load due to 40 cars is calculated by assuming passenger travelling on personal vehicle will be petrol car with BS-II <1000 cc, post The pollution load due to the vehicular traffic is given in Table 4.6 based on draft Emission Factor development for Indian Vehicles, TABLE 4.6 POLLUTION LOAD DUE TO VEHICULAR TRAFFIC S. No Parameter Car Emission Factors in gm/km Emission rate in Kg/day 1. PM CO HC NOx CO The impact on air quality will be considered due to the increased aircraft operations during operation phase. Emissions can arise from different modes of aircraft operation like idle, taxi, take-off, approach and Landing and the various emissions during these phases are CO, NO X, VOC and HC. Aircrafts burn fossil fuel (aviation gasoline, jet kerosene) and emit different pollutants related to the combustion conditions and the fuel consumption. The pollutants emitted are: CO 2, NO X, H 2 O, VOC, CO, PM and SO X. The combustion conditions (temperature, atmospheric pressure, etc) and fuel consumption during the various phases of flight (taxi, take off/landing, cruise) will have different emission factors. Emissions during operation phase have been worked out using aircraft emission factors. As per DPR, 1 flight is expected per day for the proposed airport. The emission factors and emission load per day due to aircraft are presented in Table 4.7. The total emissions will increase by 0.6 ton/day due to the operation of the proposed project. Greenhouse Gases and Climate Change: One of the environmental treats today is the potential long-term changes in the earth s climate and temperature patterns known as Global Climate Change. Many chemical compounds found in the Earth s atmosphere act as greenhouse gases. The main Green House Gases are Water Vapour, Carbon dioxide, Methane, Nitrous Oxides, Ozone and Hydro Fluoro Carbon. The total increase in green house gases due to the proposed project will be about 0.6 tons per day i.e. 228 tons per year. Chapter 4 Page 52

CO HC NOx CO SO * Airport Air Quality Guidance Manual, ICAO, Preliminary Edition Noise Pollution During operation phase of the project, noise will be generated due to the movement of aircrafts. Other domestic noise source in the vicinity of airport during operation period is due to the passenger car movement outside airport. The impact on ambient levels due to vehicular traffic during this phase will be marginal limited to parking area of airport. Therefore it could be concluded that noise in the operation phase of the project due to vehicular traffic would have minimal or no negative impact. The major source of noise from aircraft is the machinery noise from fan, compressor, turbine blades, engines and the primary jet. Primary jet noise is contributed by the mixing of high velocity exhaust gas from the engine. The expected noise levels during various modes for aircraft are presented in Table 4.8. TABLE 4.8 NOISE LEVELS IN OPERATION MODE S. No. Source Noise Level db(a) Time in Minutes 1 Taxiing / ground / idle Take-off Approach During the propagation of sound through the atmosphere, the sound is absorbed /reduced into the atmosphere due to various losses. These losses depend on temperature, atmospheric pressure, humidity and sound frequency. The ground attenuation is due to the result of the interference between direct and indirect sound waves. The characteristics of the ground are the most complex part of the ground attenuation issue. It depends on many factors, such as surface type, roughness, porosity etc. For estimation of noise contours around the airport, Integrated Noise Model (INM) version 7.0C developed by Federal Aviation Administration (FAA) is used. INM is standard tool to predict the noise in the vicinity of aircrafts and heliports. The model utilizes flight track information, fleet mix, standard and user defined aircraft/helicopter profiles and terrain as Chapter 4 Page 53

It produces noise exposure contours that are used for land use compatibility maps, and also includes built in tools for comparing contours and utilities that facilitate easy export to commercial Geographic Information Systems (GIS). As per Requirement and Procedure for Monitoring Ambient Noise Levels due to Aircrafts by CPCB published in June 2008, Day-Night Average Sound Levels (DNL) shall be used to know the sound exposure on people / residents due to aircrafts and for land use planning around airports. DNL is the Energy Averaged Sound Level (Leq) measured over a period of 24 hours with a 10dB penalty applied to night time (10.00 pm to 6.00 AM) sound levels to account for increased annoyance during the night hours. In the study, Leq and Maximum sound levels (Lmax) are used to assess the aircraft noise and depicted through noise contour as shown in Figure 4.2 and Figure 4.3 respectively. For the proposed airport, no night operations are proposed. From the figure it is observed that the predicted noise levels are above the CPCB ambient noise criteria for residential zones during landing & take off operations. About 60 structures are going to affect due to noise within 200 m from the airport boundary. However these noise levels will be for short duration (less than 4 minutes for landing and 1 minute for takeoff). The number of aircraft arriving and departing from the airport is 1 number per day. Even though the frequency is very small, it is necessary to take an action to reduce the noise to acceptable limits at the nearby villages to the airport as stated in Chapter Impact on Water Environment The proposed terminal building is designed to cater 40 passengers. After the completion of the project 14.5 KL/day would be required for all the facilities. Out of the requirement, 4.2 KL/day would be required to meet passengers and officials demand, 6.8 KL/day would be required for other facilities such as floor washing and 3.4 KL/day would be required for Horticulture purposes. The water demand during operation phase will be met from the Municipal water supply. The breakup of water consumption during operation of the proposed terminal building is shown in Table 4.9. S.

Airport Runoff and Drainage: One longitudinal storm water drain exists along the runway for drainage of rain water. However the drain is chocked with mud and broken at several places. There are 2 RCC box culverts and 1 pipe culvert exists across the runway to facilitate cross drainage of water. In rainy season, portion of storm water overflows through the runway at some patches and portion of storm water crosses the runway through the culverts provided along the runway. For effective storm water drainage system, a RCC drainage network has been designed. The airport area is divided into 11 zones for early discharge of the storm water. The drainage pattern of the airport area is shown in Figure 4.4. Some part of the storm water from runway, terminal building, apron, and taxiway is being collected separately for rain water harvesting. The remaining storm water discharges into the nallas through storm drains Impact on Solid Waste Disposal Operation of airport generates solid waste from routine office activities and restaurant. The solid waste of discarded rags, cardboards, damaged boxes, aluminum foils etc, requires proper disposal at appropriate places. The assumed rate of generation of solid waste will be 6 kg/day considering 100gm/person/day. Collection and removal of refuse from airport area are important for effective vector control, nuisance abatement, aesthetic improvement, fire protection and bird control. The refuse will include garbage, rubbish and floor sweepings. Maintenance of adequate sanitary facilities is considered as the responsibility of airport administration. The collected solid waste shall be disposed regularly at designated landfill site of the town Checklist of Impacts Checklist is the list of environmental parameters or impact indicators, which the environmentalist is encouraged to consider when summarizing the potential impacts. A typical checklist identifying the anticipated environmental impacts due to the project activities are shown in Table Chapter 4 Page 57

BACKGROUND CHAPTER - V SOCIO-ECONOMIC ASSESSMENT The Naini-Saini airport in Pithoragarh town is required to be upgraded, because the runway and available infrastructures are inadequate for the commercial use as proposed. The infrastructure requires up-gradation and construction activities for various components of the airport. These activities shall require about 28 ha land. The required land is already in possession of the district administration of Pithoragarh for department of civil aviation, government of Uttarakhand. The purchase of land is executed in consensus with the land owners and district administration. Since no fresh land acquisition is required, the local people shall not be disturbed in their present setup due to the proposed project. In addition, the project shall help to grow the business, connectivity from main stream of the population as Pithoragarh and its surrounding is located in remote and connectivity with the area is not smooth. However, the construction activities shall mobilize construction agencies together with staffs in the area, which may affect present economic activities within the area of the project. The demographic changes during the construction period would stress temporarily the local environment and population. Finally operational staff shall settle down in the area to operate the project. In brief the project during construction as well as during operation period shall have impact over the demography and socio-economic structure of the project area. It shall bring positive and quantitative changes in the habitat after commencing, but shall raise some stress during construction. While implementing the project, there is a need to take into account these disturbances and losses due to the project, their impact on socioeconomic condition of the people. Governed by the consideration, an effort has been made, in this chapter, to understand the socio-economic condition of the project area in general. The opinion of project affected people / public through consultations/ discussions have been collected and the impacts of the project have been analyzed. In order to understand region, place and people in the right perspective, it is considered appropriate to take up in brief an overview of the demographic and socio-economic characteristics of Pithoragarh district of Uttarakhand in which the project site is located. Thus, it may be possible to understand the way in which the wider socio-economic and cultural context is patterned. The villages under 5 km radius drawn at the centre of runway of the project have also been considered to analyze wider influence of the project on people around. Thus it may be possible to understand the project area in general and their socioeconomic and cultural context in particular DEMOGRAPHIC DETAILS OF THE PROJECT AREA In this section, administrative structure, location and area, population, agriculture and irrigation and the socio-economic condition of Pithoragarh district has been described to evaluate the district profile. The section has also assessed the potential and weaknesses to analyze the same of the project area. Chapter 5 Page 60

Special support shall be extended in up gradation of rural infrastructure. Involve the society in the CSRP so as to ensure acceptability of the project Methodology for CSRP The CSRP shall aim to have a specific community development program for the projectaffected area, in which the following steps shall be involved: Proposed Works under CSRP in Project Area Based on the local need in the project area, Consultant has identified few area of thrust that can improve the condition of the project area. The identified works will improve the living conditions in the villages located around the project site. Depending upon the needs of people and area of vicinity, following improvements in the infrastructures could be done. The CSR may make the people living better and public opinion in favor of the project Infrastructure Development Support Works like approach road to the village, water supply up gradation, etc. shall come under this head Water Lift People of Odmatha village face lack of drinking water. The drinking water is available in plenty down to the village, which can be lifted to the village household level for drinking and other household purposes Development of Road The villages around the runway and airport suffer due to the lack of proper road connectivity. Naini-Saini, Odmatha and Sujai villages require connecting road to move comfortably. Upgradation and sifting of foot road to single lane road from Pithoragarh to Naini-Saini and Jhajhar Deol road is need as most of the villagers cross the runway and airport through this road Education Education is main concern for the villagers in the project area, as the facility is not good in the region. Most of the villagers in naini-saini village have demanded up gradation of the existing school to the level of high school. The impact on the existing Maa Nainawati public school, Naini-Saini is considered serious and suggested to shift the school building and rehabilitate the school, elsewhere away from the airport and near Naini-saini village COST ESTIMATE FOR CSRP The CSRP works has been estimated which comes out as ` Lakhs which has been kept in the civil estimates. The item wise actual cost for the work shall be decided by the project proponent in consultation with the local people as per the needs and requirements. ***** Chapter 5 Page 67

GENERAL CHAPTER - VI ENVIRONMENTAL MONITORING PROGRAM The environmental monitoring program is a vital process for the Environmental Management of infrastructure project. This helps in signaling the potential problems that would result from the construction and operation of proposed project and will allow for prompt implementation of corrective measures. The environmental monitoring is proposed during construction and operational phases. The following parameters need to be monitored: Water Quality, Sewage Treatment Plant Air and Noise Quality, Soils, and Monitoring of Rainwater Harvesting Structures 6.2. WATER QUALITY Since water contamination leads to various water related diseases, the project authorities shall establish a procedure for water quality surveillance and ensure safe water for the consumers. A detailed epidemiological study related to water borne diseases shall be carried out and the data shall be compiled for every year in the project area. This data would help the authority in finding out the trends for incidence of water related diseases prevalent in the area, which would help them to take suitable remedial measures for reducing or eradicating the occurrence of these diseases in future. Water quality of the water bodies such as bore wells and streams shall be monitored before starting the construction, during the construction phase, and for at least three years after the completion of the project. Monitoring shall be carried out at least three times a year to cover seasonal variations during construction and operation phases. Water quality shall be analyzed by applying the standard techniques prescribed by BIS. The parameters for monitoring would be for drinking water quality parameters as per BIS: During construction and operation phase, three water samples shall be collected and the monitoring locations will be from nearest bore well and stream upstream and downstream passing near to project site SEWAGE TREATMENT PLANT The project authority shall monitor the waste water generated and its treatment plant regularly during operation phase of the project. A budgetary provision of ` 7,00,000 is made for construction of sewage treatment plant. Chapter 6 Page 68

321 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand CHAPTER - VII RISK ASSESSMENT AND DISASTER MANAGEMENT PLAN A risk is combination of the probability or frequency, of occurrence of defined hazard and magnitude of the consequences of occurrence. Hazard can be defined as physical situation often following from some initiating event which can lead to accident. A risk is thus attributing of hazard OBJECTIVE OF RISK ASSESSMENT To find out values of magnitude and severity of consequences for each hazard. These will be in general but an informed judgment as to order of magnitude To use the information as means of prioritizing actions. It means which hazard requires the most work and how it will be tackled? To specify mitigation features as appropriate to each hazard To find the effectiveness of mitigation features in reducing the risk For achieving these objectives we require a complete list of hazard, a necessary precursor is thus hazard identification. When building a large system from number of smaller ones we notice that many of the hazards arise from intra -system interfaces. Air port has many interfaces outside world, air traffic control has radio and telephones, navigational aids that communicate with air craft, such as distance measuring beacons, and instrument landing system, there are road links. The runway is airside interface. As per ICAO it is defined as rectangular area on land of aerodrome prepared for landing and takeoff of aircraft. It is interface between navigation and ground force A Stepwise Approach to Risk Assessment There are two principles which should always be borne in mind when approaching a risk assessment: To structure the assessment to ensure that all relevant hazards and risks are addressed (e.g. not to overlook tasks, such as cleaning, that might take place out of normal working hours, or ancillary departments such as waste compacting); When a risk is identified, to begin assessment from first principles by asking whether the risk can be eliminated. Risk assessment proposes an approach based on a number of different steps. This is not the only method of carrying out a risk assessment; there are a variety of methodologies for achieving the same objective. There is no single right way to do a risk assessment and different approaches can work in different circumstances. A straight forward Six -step approach (incorporating elements of risk management) such as the one presented below should work well. Step 1: Identifying hazards and those at risk Looking for those things at work that have the potential to cause harm, and identifying workers who may be exposed to the hazards. Chapter - 7 Page 71

322 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand Step 2: Evaluating and prioritizing risks Estimating the existing risks (the severity and probability of possible harm) and prioritizing them in order of importance. Step 3: Deciding on preventive action Identifying the appropriate measures to eliminate or control the risks. Step 4: Taking action Putting in place the preventive and protective measures through a prioritization plan. Step 5: Monitoring and reviewing Step 6: Emergency management Emergency management (or disaster management) is the discipline of dealing with and avoiding risks. It is a discipline that involves preparing for disaster before it occurs, disaster response (e.g., emergency evacuation, quarantine, mass decontamination, etc.), and supporting, and rebuilding society after natural or human-made disasters have occurred. In general, any Emergency management is the continuous process by which all individuals, groups, and communities manage hazards in an effort to avoid or ameliorate the impact of disasters resulting from the hazards Purpose of Risk Assessment Although the purpose of risk assessment includes the prevention of occupational risks, and this should always be goal, it will not always be achievable in practice. Where elimination of risks is not possible, the risks should be reduced and the residual risk controlled. At a later stage, as part of a review programme, such residual risk will be reassessed and the possibility of elimination of the risk, perhaps in the light of new knowledge, can be reconsidered. The purpose of this risk assessment is to evaluate the adequacy of the air port and aircraft security. This risk assessment provides a structured qualitative assessment of the operational environment. It addresses sensitivity, threats, vulnerabilities, risks and safeguards. The assessment recommends cost-effective safeguards to mitigate threats and associated exploitable vulnerabilities. Component/Flowchart of risk assessment is shown in Figure 7.1. However, it is important to know that there are other methods that work equally well, particularly for more complex risks and circumstances. The approach to assessment will depend upon: The nature of the workplace (e.g. a fixed establishment, or a transitory one) The type of process (e.g. repeated operations, developing/changing processes, work on demand) The task performed (e.g. repetitive, occasional or high risk) Technical complexity.

In other cases, different approaches may be appropriate to different parts of a workplace. FIGURE 7.1 COMPONENT/FLOW CHART OF RISK ASSESSMENT Define Risk History of Aviation Accident Identify Hazard Quantitative Risk Analysis Risk Analysis Mitigation Measures Qualitative Risk Analysis Emergency Action Plan Disaster Management Plan Among the various modes of transport, flying is also hazardous, however after identifying inherent hazards and associated risk, we can mitigate features in place so that benefits can be achieved whilst the risks are reduced. History of aviation accidents in the world are given at Annexure 7.1, recent accidents in India are given at Annexure 7.2 and accidents by ATR 42 type Aircraft are given at Annexure Hazard Identification Hazard is an event, object, or circumstances that could lead unplanned or undesired event such as accident. It is source of danger. An aviation accident is the worst nightmare of every pilot or passenger that has ever ridden in an aircraft. Although air travel is one of the safest forms of transportation, accidents do happen with dramatic and terrifying results. The causes of these aviation accidents vary greatly depending on specific circumstances and problems that may develop during the flight process. Human error, Runway, Descent and landing accidents, taxi and takeoff mishaps, mechanical failures, pilot errors, fuel mismanagement, and poor weather are only some of the many plights that can lead to injuries or death in the sky. Although popular opinion may suggest Chapter - 7 Page 73

324 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand that aviation accidents are caused by bad luck, in many situations these incidents can be completely avoided through careful preparation and effective safety techniques. When flight crew and pilots do their jobs correctly, aviation accidents are much less likely to occur DETAILED DESCRIPTION ABOUT MAJOR ACCIDENTS Descent and Landing Hazard Descent and Landing accident are most common in aviation industry. They account almost for 36% of aviation mishaps. The various stages of descent and landing are as under: Aborted Landing: At the time of unavoidable circumstance pilot takes control or abandon his landing plan for safer alternative is termed as Aborted landing. It is created by runway obstruction. Sometimes aborted landing may go wrong and accident may occur. Climb Out/Takeoff Accidents: The weather condition or wind speed dramatically influence the flight plan during takeoff. Due to gusty winds plane may pitch from side to side which can further result in crash Human Error Human error is cited as being causal or contributing factor in majority of aviation accidents. Error may occur at planning stage or during execution of the plan. In reality, human error is the primary contributor to more than 70 percent of all commercial airplane accidents. Pilot error is a far more likely cause of an airplane crash than mechanical failure or bad weather conditions. "Pilot error (weather related)" represents accidents in which pilot error was the cause but brought about by weather related phenomena. "Pilot error (mechanical related)" represents accidents in which pilot error was the cause but brought about by some type of mechanical failure. "Other human error" includes air traffic controller errors, improper loading of aircraft, fuel contamination and improper maintenance procedures. Sabotage includes explosive devices, shoot downs and hijackings. "Total pilot error" is the total of all three types of pilot error. Where there were multiple causes, the most prominent cause was used. Some of the aircraft accidents due to human error are taxi and take off errors, pre-flight accidents, faulty flight maneuvers, terrain and visual illusions Weather The poor weather condition is beyond the control of pilot, air line and flight crew. Some accidents attributed to other causes involved weather as a contributing factor, as in case of improper IFR approach. Wind shear and cross wind also caused weather related accidents in VFR condition. Lighting: The accidents due to lighting are: Struck by lightning during thunderstorm Ignition of gasoline vapours emanating from the tank vent pipes by static discharge Electric power was lost following lightening strike Chapter - 7 Page 74

325 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand Wind and Wind Shear: These accidents are caused by off the side or end of the runway on takeoff. The turbulence is stream of irregular wind which influences steadiness of plane. 48% of light air craft accidents occur due to wind. Visibility/Snow: During the winter season visibility is low. Reduction in temperature may cause certain parts to freeze or jam leading to unwanted problems or complications. This if not noted in time lead to accident. Rain: Rain and thunderstorm are very dangerous to plane. Turbulence, cumulus clouds, high winds, ice, hail, lightning, loss of visibility, electrostatic discharge, tornadoes, altimetry errors, and wet runways often accompany rain and must be managed by pilots and flight crews. The heavy rain fall makes the runway slick or slippery causing to loose control and break apart. The Pithoragarh area as per records has maximum Rainfall. This will definitely create problem on the runway and visibility affecting landing and takeoff Mechanical Failure No machine is completely fool proof. In case something goes wrong everything will be wrong. The aircraft are complicated instruments needs meticulous and sophisticated technology and software. The mechanical errors account for 13 % of accidents. Some of the Mechanical Failures are Engine failure, Defective Landing gear, Lack of Maintenance, propeller blade, improper fuelling, malfunction of fuel pump, improper hardware, obstacles in and around, mechanical error, electrical malfunctions, defective ruddar, and defective gauges Other Hazards Other hazards of the aircraft include bird strike and sabotage/explosive device. Bird Strike: Birds are not always but it is threat to plane safety. During the take off there are chances of engine failure due to high altitude birds and plane may be crashed. Bird strike occurs when there is collision between bird and an aircraft. The speed of the impact is such that even light bird may cause destructive damage to fast moving plane. Sabotage/Explosive device: Fire started by passenger in order to commit suicide, An aircraft worker placed an incendiary device the starboard wheel well, Detonation of explosive device placed in the luggage in the cabin, and No security or boundary wall or fencing around the Airport Obstacles in and around Pithoragarh Airport Based on the field obstacle survey, the fixed objects around the airport were studied and their locations (distance and co-ordinates) and elevation have been noted. The information thus gathered has been processed to identify and evaluate the obstacles in the laid down surfaces. Most of the obstacles identified are hills all around the runway. Hills existing in the approach 14 are protruding the obstacle limitation surfaces by 100m. Hence landing/takeoff in this direction is not feasible. It observed that few structures present in the approach 32 infringe the OLS which are required to be notified. With the notification of these obstructions, landing and take-off is feasible on this side. Chapter - 7 Page 75

326 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand Many structures protrude the inner horizontal & Conical surface due to raising terrain conditions. A hill present on the north east side of the runway protrudes the inner horizontal surface of OLS by 427 m at a horizontal distance of about 1170 m from runway centre line. The obstructions in the Inner Horizontal Surface are significant and required to be notified for decision of minimum circling altitude. Due to the raising terrain conditions, the proposed compound wall of the airport boundary of height 3.0 m on the North-Eastern side stretch infringe the transitional surface and approach 32 at many places. All these obstructions require notification in the NOTAM and exemption from DGCA. A bituminous road connecting Naini-Saini village is passing through the proposed extension of runway area at 32 end. This road is required to be closed. The obstacle limitation surfaces have been established as per ICAO stipulations with reference to the proposed extension of runway for operations of ATR-42 aircraft for Non- Instrument Runway, Code 2. For the purpose of establishing obstacle limitation surfaces, the length of the proposed basic strip has been considered as 1630m ( x 60m). Further for calculation of obstacle limitation surfaces, reduced levels of 14 end and 32 end thresholds are taken as m (extended by m) and m (extended by 38.70m) respectively above MSL. There are about 283 obstacles in and around the existing air port which are given in Vol I of DPR. All the obstacles will be notified in Airport Information Publication and the same should be provided to pilot to avoid accidents RISK ESTIMATION/ANALYSIS A risk estimates is the estimation of the likelihood or statistical probability that harm may occur. Risk analysis is conducted in two ways 1) Qualitative risk analysis and 2) Quantitative risk analysis. These two type of risk analysis can be conducted simultaneously or in a chosen order, and even within a defined period gap Qualitative Risk Analysis The objective of conducting a qualitative risk analysis is to acquire safety against recognized risks and to increase the alertness of management, team members, and all personnel who are vulnerable to them. The risk ranking and severity of consequences are given in Table 7.1 and Table 7.2. TABLE 7.1 RISK RANKING RISK ASSESSMENT Likelihood of Harm Severity of harm Slight harm Moderate Harm Extreme Harm Very unlikely Very low risk Very low risk High risk Unlikely Very low risk Medium risk Very high risk Likely Low risk High risk Very high risk Very Likely Low risk Very high risk Very high risk Chapter - 7 Page 76

By using a quantitative approach, an organization is able to create a very precise analytical interpretation that can clearly represent which risk-resolving measures have been most well-suited to various project needs. This makes the quantitative approach favored by many management teams since risk assessments can be clearly represented in the empirical forms like percentages or probability charts, since it emphasizes using tools such as metrics. Risk can be evaluated and rank according to the severity and frequency of occurrence. Probability of occurrence and frequency can be calculated after ranking the level of risk at various levels of operation. The percentage of risk is calculated on the basis of accidents occurred in the past all over the world which is reported in Detailed Hazard Identification for Airport accident causes and analysis is present in this chapter. The risk rating and quantitative risk analysis for the project are given in Table 7.3 and Table 7.4.

Take off and initial climb: The aircraft accelerates, lift off and starts climbing. The site of Naini Saini Airport has hillocks on all sides of the runway. On the direction of the take off also hillock exist. Besides this one communication tower also exist. Therefore while climbing there are chances of plane hitting on the hilltop due to human error or engine failure. This may result into major casualty which is fatal. Frequency of occurrence of this type of risk is very rare. 2. Descent and Initial Climb: The aircraft descends to get closer to its destination airport. Air traffic control may request the aircraft to loiter and wait its turn for the next phase. Over half of all accidents occur during the final approach and landing stages. These aren t the most devastating accidents; however a runway overrun may result in only a few injuries. Frequency of occurrence of this type of risk is very rare. 3. The length of runway is just sufficient as per the norms. Therefore after landing of the speed of the aircraft is not controlled by the pilot it will skid further and stop. There will be minor injury to passenger and casualty is not fatal. Frequency of occurrence of this type of risk is very rare. 4. There are chances of tyre burst due to sharp object on the runway. This will lead skidding of aeroplane causing minor injury to pilot, crew and passengers. Frequency of occurrence of this type of risk is once in 10,000 landings RISK MITIGATION MEASURES Mitigation measures are recommended actions to reduce, avoid or offset the potential adverse environmental consequences of development activities. The objective of mitigation measures is to maximise project benefits and minimise undesirable impacts. The total elimination of human error would be an unrealistic. The challenge then is to prevent Chapter - 7 Page 78

329 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand errors but to learn to safely manage the inevitable errors. It is prevented by error reduction strategy, error capturing and error tolerance Human Error Control - PAVE (Pilot, Aircraft, Environment, External Pressure) Using PAVE helps to identify risk before departure and assists the pilot s decisionmaking process. With the PAVE checklist, pilots have a simple way to remember each category to examine for risk prior to each flight. Once a pilot identifies the risks of a flight, he or she needs to decide whether the risk or combination of risks can be managed safely and successfully. If not, make the decision to cancel the flight. If the pilot decides to continue with the flight, he or she should develop strategies to mitigate the risks. One way a pilot can control the risks is to set personal minimums for items in each risk category. A) Pilot: A pilot must continually make decisions about competency, condition of health, mental and emotional state, level of fatigue, and many other variables. When most people make mistakes at their jobs, their employment can be terminated. When pilots are negligent or make errors while on the job, there is the potential for hundreds of lives to be terminated. Pilots receive extensive training designed to prepare them to handle a wide variety of situations, but there are times when fatal mistakes are made. One of the best ways pilots can mitigate risk is a self evaluation to ensure they are in good health. A standardized method used in evaluating health employ is the I M SAFE checklist. It can easily and effectively be used to determine physical and mental readiness for flying and provides a good overall assessment of the pilot s well being. B) Aircraft: A pilot frequently bases decisions on evaluation of the airplane, such as performance, equipment, or airworthiness. During a pre-flight, a pilot noticed a small amount of oil dripping from the bottom of the cowling. Although the quantity of oil seemed insignificant at the time, the pilot decided to delay the takeoff and have a mechanic check the source of the oil. The pilot s good judgment was confirmed when the mechanic found that one of the oil cooler hose fittings was loose. C) Environment: The environment encompasses many elements that are not pilot or airplane related, including such factors as weather, air traffic control (ATC), navigational aids (NAVAIDS), terrain, takeoff and landing areas, and surrounding obstacles. Weather is one element that can change drastically over time and distance. D) External Pressures: The interaction between the pilot, airplane, and the environment is greatly influenced by the purpose of each flight operation. The pilot must evaluate the three previous areas to decide on the desirability of undertaking or continuing the flight as planned. It is worth asking why the flight is being made, how critical it is to maintain the schedule, and if the trip is worth the risks. External pressures are influences external to the flight that create a sense of pressure to complete a flight - often at the expense of safety. Management of external pressure is the single most important key to risk management because it is the one risk factor category that can cause a pilot to ignore all other risk factors. External pressures place time-related pressure on the pilot and figure into a majority of accidents. The use of personal standard operating procedures (SOPs) is one way to manage external pressures. The goal is to supply a release for the external pressures of a flight. Chapter - 7 Page 79

330 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand Weather Weather is a major environmental consideration. As pilots set their own personal minimums, they should evaluate the weather for a particular flight by considering the following: What are the current ceiling and visibility? In mountainous terrain, consider having higher minimums for ceiling and visibility, particularly if the terrain is unfamiliar. Consider the possibility that the weather may be different from forecast. Have alternative plans and be ready and willing to divert should an unexpected change occur. Consider the winds at the airports being used and the strength of the crosswind component If flying in mountainous terrain, consider whether there are strong winds aloft. Strong winds in mountainous terrain can cause severe turbulence and downdrafts and be very hazardous for aircraft even when there is no other significant weather. Are there any thunderstorms present or forecast? If there are clouds, is there any icing, current or forecast? What is the temperature-dew point spread and the current temperature at altitude? Can descent be made safely all along the route? Terrain Evaluation of terrain is another important component of analyzing the flight environment. To avoid terrain and obstacles, especially at night or in low visibility, determine safe altitudes in advance by using the altitudes shown on visual flight rules (VFR) and instrument flight rules (IFR) charts during preflight planning. Use maximum elevation figures (MEF) and other easily obtainable data to minimize chances of an inflight collision with terrain or obstacles Obstacles in and around There are many hills around the air port. The height of these hills is to be reduced as per ICAO rules. It is proposed to notify the hills with DGCA and keep the height as per the guidelines of ICAO. Besides this the red light indicator required to place on top of the hills. Even in the day time also certain marks or flags or glow signage should be placed on hills which are visible in the daylight Runway End Safety Area As the runway at Pithoragarh will be of code 2 non instrument, provision of RESA is not mandatory, as per Annexure -14 of ICAO and DGCA Civil Aviation Requirements. However, provision of RESA for all the airports is under consideration by ICAO. Therefore, provision of RESA of length 60m and width 60 m (the maximum possible within the available land) is proposed at both the ends of the runway strip, to protect the aircraft in the event of undershooting or over running the runway, within the available land. Runway Dimensions: Keeping into consideration the limited length of land available, it is proposed to provide a runway of length 1510 m which will be sufficient for operations of ATR 42 to meet the destinations within a range of 350 km. This is the maximum length of Chapter - 7 Page 80

331 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand runway that can be provided within the available land leaving clearances for the boundary wall in the approach. Runway Lighting: Although the night operations on the air port are not planned it is necessary to have lighting along the runway also as during rainy season and winter visibility is low. Debris Removal: The best mitigation for debris is good House Keeping. Make sure that things are not dropped, augmented by observation and sweeping activities. There will be schedule of inspection activities to be carried out by operation department. This inspection should check damage, or contaminant on the pavements. Collision Hazard on Runway: The runway is an interface which can be referred as Terminal of the air space. This area covers arrival route and departure route. The ground connections are taxi ways which are holding points until they are permitted to use the runway. Properly defined holding points and good housekeeping of runway will completely eliminate collision on the runway Mechanical Failure The good maintenance and replacement of worn part regularly will reduce mechanical failure. Improper Fuelling: The quality of fuel should be checking before refuelling. It should adhere to the standards issued by ICAO. Improper Hardware: The hardware used in the air craft should be ICAO approved. There should not be any compromise on the quality of hardware. Design Flaw: All the parts of engine and air craft should be flawless from design and construction angle Sabotage/Hijacking To prevent sabotage following measures can be implemented: Identification Badges for Employees All Airline employees are issued photo identification cards Employees should have their I.D.s in their possession during the duty and it should be shown upon request Ground Security The complete fool proof program of ground security should be established to prevent sabotage the air craft and airport. The air craft or air port should be guarded all the time. Unauthorized person or visitor may not be permitted to enter restricted premises. Instructions should be given to employees to keep watch all passengers and in case suspicious movement noticed, they should inform security. Screening of passengers at entry point before proceeding to the air port area, Screening of hand Baggage and Check in luggage, Security boundary wall around the Airport, and Chapter - 7 Page 81

332 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand All carry-on baggage passing through the screening point must be inspected physically or with an X-ray device. Articles cleared by this inspection may pass the screening point and be carried into the aircraft cabin. In case a customer refuses to inspect of any hand-carried articles, such articles will not be permitted Weapons Air port security should remove deadly or dangerous weapon from passenger or crew member attempting to cross security check point. The air port management has to develop the Aerospace Performance Factor (APF) concept, for risk-based decision making and mishap prevention. Mishap reduction is vital to the future of safe air transportation. The aerospace performance will shift safety from the rearview mirror to forward-looking radar. It will proactively integrate safety into operational thinking. The APF will be a key component to any aviation safety management system. Using advanced analytics and visualization will be a powerful, indispensable tool for aviation safety Landing and Take-Off In the occurrence of any take-off and landing aircraft accident, there are different influencing parameters such as airport infrastructures, type of aircraft involved, meteorological conditions, as well as human factors differ from one situation to another that make the analysis of aircraft accident probabilities much complicated. Project risk mitigation attempts to anticipate and provide a solution regarding the uncertainties that pose a threat to project objectives and terms, to identify all the foreseeable risks, assessing the chance and severity of those risks, and then deciding what might be done to reduce their possible impact on the project or avoid them entirely DISASTER MANAGEMENT PLAN The study and analysis of factors that cause a disaster, the characteristics that shape its evolution, the effects on the population and the natural environment, the instruments that can mitigate their effects, and the various ways of re-establishing the optimal living conditions of the persons and communities involved have led to the creation of the new science of Disasterology, which studies disasters from all points of view and establishes guidelines for their management. A Disaster Management Plan (DMP) is an integral part of an Airport operation for effective and safe management of technical and non-technical emergencies. This is important for effective management of an emergency situation to minimize losses to people, property and both at and around the Airport. The objectives of the emergency planning are to describe the Airport's emergency response organization, the resources available and applicable response actions. Thus, the objectives of emergency response plan can be summarized as follows: Rapid control and containment of the hazardous situation; Minimizing the risk and impact of an event/accident; and Effective rehabilitation of the affected persons, and prevention of damage to property. Chapter - 7 Page 82

333 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand Disasters are always unwanted part of situation & difficult to control. Aviation disasters create huge losses of property and people. Disaster control plans are successfully established, operated & thus involvement of local people is paying in time. To be prepared in advance for any sort of disaster which may occur as a consequence of natural calamities is utmost important. Disaster control plan gives ideas to plan in advance to avoid & minimize the damage in all aspects. It is a team effort & remarkably pays if due attention is paid in time to plan & execute the action plan for disaster control. As the name suggests the team members in this plan are many & all must know their duties to perform their respective roles in least time, at positions asked & as per needs of the situation arises Onsite and Offsite Emergency Plan A major emergency can be defined as an accident/ incident that have potential to cause serious injuries or loss of life. It may cause extensive damage of property and may adversely affect the environment. On-Site Emergency: If accident / incident takes places in an Airport, its effects are confined to the Airport premises, involving only the persons working in the Airport and the property inside the Airport it is called as On-site Emergency. Off-Site Emergency: If the accident is such that it affects inside the Aircraft are uncontrollable and it may spread outside the Airport and affect the premises, it is called as Off-site Emergency. The main objectives of an emergency plan are to control and contain the incident/ accident and if possible, eliminate it and to minimize the effects of the incident on person, property and environment. Each Airport should prepare an emergency plan incorporating details of action to be taken in case of any major accident/ disaster occurring inside the Airport. The plan should cover all types of major accident/ occurrences and identify the risk involved in the airport. Mock drills on the plan should be carried out periodically to make the plan foolproof and persons are made fully prepared to fight against any incident in the airport. The Emergency Control Centre (ECC) shall ensure a mock drill of the onsite emergency plan is conducted at least one in every six months. A detailed report of the mock drill conducted under rule shall be made immediately available to the Inspector and Chief Inspector. Main elements of On-site Emergency plans:- Leadership and Administration, Role and Responsibilities of Key Personnel, Emergency action, Light and Power, Source of energy control, Protective and rescue equipment, Communication, Medical care, Mutual Aid, Public relation, Chapter - 7 Page 83

These headings are listed below together with a description of the type of emergency. Local Standby: Local standby will be declared when an Aircraft approaching the Airport is known or is suspected to have developed some defect but the trouble does not normally involve any serious difficulty in effecting a safe landing. Aircraft Disabled/Taxiway: An incident such as, hydraulic leakage/failure, undercarriage failure or any other technical problems, the aircraft can be disabled or immobilized on the taxiway. Situation like this may require the pilot to disembark the passengers onboard in situ before the Aircraft is removed or towed to its parking bay. To specifically deal with such a situation, a plan will be developed. Full Emergency: Full Emergency will be declared when an Aircraft approaching the Airport is known or is suspected to be in such trouble that there is a possibility of an accident. Crash Action: Crash Action will be declared for Aircraft accidents on the Airport. There are two types of Crash Action - for Aircraft accidents that occur within the Airport Fire Service Turnout Area and for that occur outside the Airport Fire Service Turnout Area. In-Flight Mass Casualties: Part 1 of ICAO Annexure 6 stipulates that the pilot-in-command shall be responsible for notifying the nearest appropriate authority by the quickest available means of any accident involving his Aircraft, which results in serious injury or death to any person or substantial damage to the Aircraft or property. Mass casualties onboard will usually result from incidents such as an encounter with air turbulence during flight and food poisoning. Fires on the Ground: Fires on the ground can be Aircraft related and non-aircraft related. Fires involving aircraft can be at any location on taxiway or apron area where the aircraft is parked. Non-aircraft related fires involve mainly the Airport buildings and installations. Natural Disasters: The natural disasters to which Airport are likely to be subjected to are earthquake, flood, thunder and storms. Depending on the intensity, such acts of nature may cause severe destruction to the Aircraft, Airport buildings and installations, and even loss of Chapter - 7 Page 90

To test, efficiency, timing, and content of the plan and implementing procedures; To make certain that the emergency organization staff are familiar with their duties and responsibilities by demonstration; To provide hands-on experience with the procedures to be adopted during emergency; and To maintain emergency preparedness. The frequency of the drills conducted will be once in a year. Scenarios may be developed in such a manner as to accomplish more than one event objective. Drills and exercises will be conducted as realistically as is reasonably practicable. Mock drills and exercises would include: Dates, times and places; Participating organizations; Events to be simulated; Approximate schedule of events; Arrangements for qualified observers; and An appropriate critique of drills/exercises with participants. Evaluation of drills and exercises will invite comments from the participants and observers. Discrepancies noted by the drill observers shall be pointed out. The team responsible for conducting the drill or exercise would prepare a written evaluation which will include assessments and recommendations on: Areas that require immediate correction; Areas where additional training is needed; Suggested modifications to the plan or procedures; and Deficiencies in equipment, training, and facilities. Records of drills, exercises, evaluations, and corrective actions would be duly maintained UPDATING DISASTER MANAGEMENT PLAN The Disaster Management Plan and implementing procedures would be reviewed and updated to ensure compliance with relevant regulations and applicable state and local emergency plans. The need for updating is based on following aspects: Chapter - 7 Page 97

348 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand Written evaluations of mock drills exercises which identify deficiencies or more desirable methods, procedures, or organizations; Changes in key staff involved in the organization; Changes in the facility organization structure; Changes in regulations; Recommendations received from other organizations and state agencies SAFETY MANAGEMENT PROCESS Safety management is evidence based, in that it requires the analysis of data to identify hazards. Using risk assessment techniques, priorities are set to reducing the potential consequences of hazard. Safety Management Plan is shown in Figure 7.3 and the steps in safety management process are described as below: i. Collect the data: the first step of safety management process is the acquisition of relevant safety data - the evidence necessary to determine safety performance or to identify latent unsafe conditions (safety hazards). The data may be derived from any part of system, the equipment used, the people involved in the operation, work procedure, the human/ equipment/procedures/interactions, etc. FIGURE 7.3 SAFETY MANAGEMENT PLAN Collect Data Re-evaluate Situations Collect Additional Data Analysis Data Implement Strategies Assign Responsibilities SAFETY MANAGEMENT PLAN Prioritize Unsafe Conditions Develop Strategies Approve Strategies ii. iii. iv. Analyse the data: By analysing all the pertinent information, safety hazard can be defined. The condition under which the hazard poses real risk, their potential consequences and the likelihood of occurrence can be determined. This analysis can be both qualitative and quantitative. Prioritise the unsafe conditions: A risk assessment process determines the seriousness of hazards. Those posing the greatest risk are considered for safety action. Develop strategies: Beginning with highest priority risks, several options for managing the risks may be considered, eg. Chapter - 7 Page 98

349 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand a. Spread the risk across as large a base of risk takers as practicable. b. Eliminate the risk entirely possibly by ceasing that operation or practice. c. Accept the risk and continue operation unchanged d. Mitigate the risk by implementing the measures to reduce the risk or at least facilitate coping with the risk. v. Approve strategies having analysed the risks and decided on an appropriate course of action, management approval is required to proceed. The challenge in this step is the formulation of a convincing argument for (perhaps expensive) change. vi. Assign responsibilities and implement strategies: Following the decision to proceed the nuts and bolts of implementation must be worked out. This includes a determination of resource allocation, assignment of responsibilities, scheduling, revisions to operating procedures, etc. vii. Re-evaluate situation: Implementation is seldom as successful as initially envisaged. Feedback is required to close the loop. What new problems may have been introduced? How well is the agreed strategy for risk reduction meeting performance expectation? What modifications to the system or process may be required? viii. Collect additional data: Depending on the re-evolution step, new information may be required and the full cycle reiterated to refine the safety action. Safety management requires analytical skills that may not be routinely practised by management. The more complex the analysis, the more important is the need for the application.

POSITIVE IMPACTS CHAPTER - VIII PROJECT BENEFITS Based on project particulars and the existing environmental conditions potential positive impacts have been identified those are likely to result from the proposed project. This section deals with the positive impacts. Positive impacts have been listed under the following headings: Employment Opportunities Improvement in Aesthetics Better Tourism Employment Opportunities The construction phase of the project is spread over a period of 18 months. During this period the manpower / labour will be needed to work as mason, carpenter, coolie, fitter, etc. Due to this project, the local population will get the employment based on the skills they have. About 100 persons per day are likely to work during the peak periods. In the post construction phase, the project will provide social benefits in terms of direct / indirect employment by way of better commercial development of the area due to increase in number of tourists Improvement in Aesthetics The project will lead to improved aesthetics of the surrounding by way of providing a pleasing architectural design. The green belt that will be provided around the proposed terminal building would also enhance the aesthetics Better Tourism The project will be a facility for landing and taking off the flights. This will facilitate the increasing demand of tourist and passengers in time to come. Pithoragarh is the gateway for important tourist destinations like high Himalayan Mountains, Snow Capped Peaks, passes, Valleys, Alpine Meadows, Forests, Waterfalls, perennial rivers, Glaciers and springs. Increased air transportation facility would attract more tourists, which will work as a catalyst for economic growth of Pithoragarh. ***** Chapter - 8 Page 100

GENERAL CHAPTER - IX ENVIRONMENTAL MANAGEMENT PLAN The Environmental Management Plan (EMP) contains a description of proposed remedial measures and monitoring plan for the construction and operational period of the project. The EMP often contains construction / management guidelines that specifically address how the contractors are to incorporate environmental considerations into their work. EMP considers compensatory measures if mitigative measures are not feasible or cost-effective. This chapter spells out the set of measures to be undertaken during project construction and operation to mitigate or reduce the adverse environmental impacts and bring them to acceptable levels based on the proposed Environmental Management Plans. The most reliable way to ensure that these plans are integrated into the overall project planning and implementation is to include them as an integral component of the project. This ensures that it will receive funding and supervision along with other investment components. For optimal integration of EMP into the project, there should be links for: Funding, Management, training and Monitoring. The purpose of the first link is to ensure that proposed actions are adequately financed. The second link helps in embedding training, technical assistance, staffing and other institutional strengthening items in the mitigation measures to implement the overall management plan. The third link provides a critical path for implementation and enables sponsors and the funding agency to evaluate the success of mitigation measures, as part of project supervision, and as a means to improve future projects. For every impact; the mitigation measures, implementing agency and budget have been presented as far as possible. All required funds would be channeled through the project authority. The Environmental Management Plans have been prepared and discussed in subsequent sections ENVIRONMENTAL MANAGEMENT PLANS EMP contains set of mitigation measures for lessening of negative environmental impacts through: a) changes in the design, construction practices, maintenance, and operation; and b) additional actions taken to protect the biophysical and social environment, as well as individuals who have been impacted adversely by a project. The extent and timing of mitigative actions are based on the significance of the predicted impacts. Mitigation measures require implementation during pre construction, construction and operation phase to ensure that proposed actions are carried out at the correct times. Based on project description (Chapter - 2), Environmental Baseline Data (Chapter - 3) and Environmental Impacts (Chapter - 4), the environmental management plans to be adopted are presented below. Chapter - 9 Page 101

352 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand 9.3. PRE-CONSTRUCTION STAGE The parameters need to be considered during the pre-construction stage are: Water Conservation Compensation for Loss of Land, Energy Conservation Measures, Construction Material Management, Borrow Area Management Removal of Obstacles and Fire Fighting Water Conservation Water demand during construction phase will be provided by the contractor and during operation phase will be met from municipal supply. Water problem in the water crises area is reduced by rainwater harvesting through capturing the runoff. For the proposed project rain water harvesting considered during design stage of the project which will be done by capturing runoff from roof areas of buildings (terminal building, ATC, fire building, guest house, electrical substation, etc), apron, taxiway and parking area. The rooftop rain water reused during operation phase of the project will be 1.22 ML per year. The estimated cost for rain water harvesting structures is kept in civil estimates. Reduction in fresh water/water requirement: Various measures to reduce the consumption of water that will be followed are Reduction of toilet cistern volume in single flush models, Promotion of awareness on water conservation and reducing water usage, Promptly attending the water leakage, Providing urinals and wash basins with automatic sensors and WCs with flushing valves, Sprinkler irrigation system for watering of green spaces, Plants with less water requirement Compensation for Land The general principle is that all those who loose land or their means of livelihood should be suitably compensated to achieve sustainable development. For this project about 28 ha of land is required, which is already in possession with USIDCL Energy Conservation Measures Energy conservation measures are often the easiest, quickest and cheapest way to reduce costs and benefit the environment. Energy conservation program will be implemented through measures taken both on energy demand and supply. The amount of energy used for lighting varies from industry to industry, but typically, lighting accounts for approximately 50% of the electrical load in office building. By having an understanding of the lamps, ballasts, luminaries and control options available today as well as the techniques used to Chapter - 9 Page 102

353 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand develop efficient lighting, cost effective yields a higher quality of light. Energy conservation plan is shown below. Supply Energy Conservation Demand Utilize energy efficient diesel generators Exploring the possibilities of introducing renewable energy Reduce consumption Use energy efficient appliances Energy efficient practices Segregation of areas for light points Improvements in lighting efficiency have been provided in the building by adopting following measures: Lamps - replacing inefficient lamps with the most efficient lamp for the purpose, taking into account size, shape, colour and output of the lamp. Ballasts - replacing standard choke ballasts with high frequency electronic ballasts. Luminaries - retrofitting standard luminaries with high-efficiency spectacular reflectors or replacing standard luminaries with high-efficiency luminaries. Localized Switching - installing localized switches near work stations to control local lighting. Lighting design - (a) designing lighting systems that maximize the use of daylight and (b) introducing local task lights (e.g. desks lights), allowing a reduction in general overhead lighting. Maintenance Schedule - setting up a maintenance schedule to clean and replace lamps on a regular basis. Promoting employees awareness on energy conservation Training staff on methods of energy conservation and to be vigilant to such opportunities Construction Material Management The major construction material to be used for construction of Airport are coarse aggregates, cement, bituminous, coarse sand, reinforcement steel, structural steel, water supply, drainage and sanitary fittings. The material will be loaded and unloaded by engaging labor at both the locations by the contractor. The duties of the contractor will include monitoring all aspects of construction activities, commencing with the storing, loading of construction materials and equipment in order to maintain the quality. During the construction period the construction material storage site is to be regularly inspected for the presence of uncontrolled construction waste. Close liaison with the USIDCL and the head of the construction crew will be required to address any environmental issues and to set up procedures for mitigating impacts in terms of disturbance to biota, sampling of the ground and control of litter. The scheduling of material Chapter - 9 Page 103

354 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand procurement and transport shall be linked with construction schedule of the project. The Contractor shall be responsible for management of such construction material during entire construction period of the project. Sufficient quantity of materials should be available before starting the each activity.

Moreover, the emissions due to operation of construction machinery also add to the ambient air pollution level. Temporary impacts on air quality from dust would be mitigated with standard construction practices, including wetting of exposed soils, limiting vehicle operation on unpaved surfaces and limiting the extent and duration of exposed areas. The measures, which need to be adopted to reduce the dust concentration, mobile source emissions are presented below: Dust Control Measures: Dust generated by construction activities shall be kept to a minimum by full implementation of the following measures: During clearing, grading, earth moving, excavation, or transportation of cut or fill materials, water trucks (for sprinkling of water) are to be used when necessary to prevent dust from leaving the site and to create a crust after each day's activities cease; During construction, water trucks shall be used to keep all areas of vehicle movement damp enough to prevent dust from leaving the site; Stockpiled earth material shall be sprayed as needed to minimize dust generation. During construction, the amount of disturbed area shall be minimized; Onsite vehicle speeds should be reduced to 10 kmph or less; Exposed ground areas (that are left exposed after project completion) should be sown with a fast-germinating native grass seed and watered until vegetation is established; After clearing, grading, earth moving, or excavation is completed, the entire area of disturbed soil shall be treated immediately by watering or re-vegetation or spreading soil binders to minimize dust generation until the area is paved or otherwise developed so that dust generation will be minimized; Grading and scraping operations shall be suspended when necessary to minimize dust generation; and All roadways, driveways, and sidewalks associated with construction activities should be paved as soon as possible. Emission Control Measures: Emissions from the vehicles shall be kept to a minimum by full implementation of the following measures: Chapter - 9 Page 105

356 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand Idling of delivery trucks and other construction equipment should not be permitted during the periods when they are being unloaded / loaded or are not in active use; The emission levels from diesel vehicles being used should be checked on monthly basis and brought to the required levels of emission standards; Concrete batching plant should be located at or near the project site so that the requirement of delivery trucks are minimized; and The work schedule and the operation time of construction machinery should be suitably modified and have limited construction activity to exercise a control on ambient air quality standards. The mitigation measures, which would be adopted to reduce the stationary source emissions, are presented below: Crusher plant shall be located at least 500m away from the habitation and on the barren land so as to avoid / cause minimum damage to the population during construction. Contractor operating the crusher plant would fulfill the requirements laid down by Uttarakhand State Pollution Control Board in terms of pollution control in operating the crusher plant. Every day the haul road at the construction site be inspected and the debris left by the trucks to be removed as early as possible. The quarry operations, from which the aggregates for construction are sourced, will have to fulfill the requirements laid down by the Uttarakhand State Pollution Control Board. Proper care should be taken for storage of oil to avoid oil spillage and soil contamination. The work schedule and the operation time construction machinery to be suitably modified and have limited construction activity to exercise a control on ambient air quality standards. During Construction Phase, the NOx concentration may increase than present levels. This impact will be intermittent only (short term). Following measures need to be taken to reduce the NOx: To use gas based generation system, Scrubber to be installed at the outlet of the DG sets Noise Control Measures During the construction phase, there would be an increase in ambient noise levels due to construction machinery, and movement of construction vehicles. From the Chapter - 4, construction activities are expected to produce noise levels at source in the range of db (A), which will decrease with increase in distance. For an approximate estimation of dispersion of noise in the surroundings from the source point a standard mathematical model for sound wave propagation is used. The equation for sound wave propagation used as discussed in Chapter 4. Chapter - 9 Page 106

357 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand For modelling purposes, flat terrain is considered and environmental attenuation factors are not considered so as to formulate the worst case scenario. The permissible limits during day time for different land use categories from the above equation are given in Table 9.1. TABLE 9.1 MINIMUM DISTANCE REQUIRED FOR OPERATING STATIONARY EQUIPMENTS Category Permissible limits in Day time (CPCB) Distance required (m) Silence zone 50 db(a) 200 Residential 55 db(a) 113 Commercial 65 db(a) 36 Industrial 75 db(a) 11 From the table it may be noted that residents within 113m from the construction activity will be exposed to a noise higher than the permissible limit whereas the owners of commercial establishments within 36m from the construction activity will be affected. The impacts will be significant on construction workers, working close to the machinery as well as to the commercial and residential areas within the predicted zones. The overall noise impacts during construction will be for short-term (for day time only). The following mitigation measures may reduce the noise impacts during construction stage. The construction yard shall be located at least 100m distance away from any residential areas; Special acoustic enclosures shall be provided for individual noise generating construction equipment such as cement concrete mixers, generators. The special acoustic enclosures may be provided by way of noise shields, which can be either brick masonry structure or any other physical barrier, which is effective in adequate attenuation of noise levels; To ensure that vibration is minimized during construction activities, contractors shall use equipment that is properly muffled and is maintained in good operating condition; Noise measurement shall be conducted during construction to assess the prevailing noise levels. If noise level exceeds the limits (ambient standards) then the source of noise shall be identified and proper measures for noise reduction shall be applied; Noise levels from loading and unloading shall be reduced by usage of various types of cranes and by placing materials on sand or on the beds of sandy bags; Project construction activities that generate noise in excess of 60 db at the project site boundary shall be limited to the hours of 7 a.m. to 6 p.m.; and The exposure of workers to high noise levels especially, near the construction site shall be minimized during construction period by: 1. Job rotation: The workers employed in the high noise level area shall be employed in the low noise level area and vice-versa from time to time. 2. Protective devices: The protective devices such as ear plugs shall be provided to the workers. 3. Noise barriers: The operation of the construction equipments in this project can record noise levels up to 85 db (A) at a distance of 15m.

359 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand Crèches shall be properly maintained and necessary equipments like toys, etc. provided. On completion of the works, the whole of such temporary structure will be cleared away, all rubbish burnt, excreta or other disposal pits or trenches filled in an effectively sealed off and the whole of the site left clean and tidy, at the contractor's expense, to the entire satisfaction of the site-in-charge engineer Water Supply and Sanitation The public health facilities, such as water supply, sanitation and toilets are much needed at project site during construction phase. The water demand required during construction phase is discussed in Chapter - 4. The contractor has to arrange for this quantity from outside the project area. It is recommended that, chlorine tablets should be used to treat water so as to render it safe for drinking and other purposes. This will help in reduction of water borne diseases among the workers and will also reduce the possibility of disease hazard in the area. During construction, the quantity of wastewater will be about 3.6 KL/day. Individual sewerage disposal system by way of septic tank followed by oxidation pond is proposed for sewage from contractor's workers camp, since it is not possible to provide a full sewerage system. Care shall be taken for location of these septic tanks so that they do not pollute the water sources. One community toilet with flushing system could be provided per 20 people. The sewage from community toilet would be treated through septic tank and disposed off through oxidation pond. Generally, for 1400 people one septic tank would be provided. At least one community toilet would be provided at each camp site. The drinking water facilities and sewage disposal sites should be located away from each other. About ` 9.5 Lakhs will be required for these facilities as reported in Table 9.2. S. NO. TABLE 9.2 COST OF WATER SUPPLY AND SANITATION FACILITIES DESCRIPTION RATE (`/ UNIT) NUMBERS COST (`) 1 Water treatment and supply facility 1,00, ,00,000 2 Community Toilets 30, ,50,000 3 Septic Tanks including connection 4 Oxidation Pond including disposal 5,00, ,00,000 1,00, ,00,000 TOTAL 9,50, Oil Spill Control/ Management During construction and operation of project activities various equipments and construction vehicles generate oil & grease, which are likely to spoil the natural environment. These oil spills may enter in the runoff, which ultimately contaminate the natural drains. Oil and grease removal trap will be provided in the storm water collection system. Oil and grease will be separated out in a container for sell/disposal. To control the oil spill during construction stage of the project following measures should be taken: Chapter - 9 Page 109

360 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand Good housekeeping Routine checkup of construction machineries and equipments Temporary cement/metal platform will be provided below the construction machineries and at maintenance site to capture the spill. These platforms should be at sufficient height to avoid the littering Conducting routine inspections to ensure proper functioning with less emission. The cost of oil and grease trap and allied facilities should have part of Storm Water System and will be involve in the contract documents Solid Waste Management As per CPHEEO manual, the solid waste generation from the residential areas will be kg/capita/day. The past experience of such projects indicates that about 0.2 kg/ person/ day of solid waste is generated from the workers camps, which means that the total solid waste generation will be about 48 kg/ day, for which adequate collection, conveyance and disposal facilities shall be provided. The solid waste shall be disposed at the appropriate Government designated landfill in the nearby area. One garbage collection bin of about 20 litres capacity with handle and cover would be provided among ten people; in addition four community bins at different locations would be provided for effective collection of the waste. The cost of these facilities including maintenance for 24 months works out to about the cost of ` 4.26 lakhs Reuse/Recycling of Construction Waste Material Left over at the site and generated from demolishing structures like concrete & mortars, cement concrete blocks, aggregate, sand and other inorganic material will be disposed in low laying areas of airport in basic strip within a lead of 1 km. Existing structures to be demolished and quantities of materials of buildings to be demolished are given in Annexure 9.2. Reuse of this will also save an equivalent quantity of aggregate. As a result, there would not be any inorganic solid waste rendered surplus from the project and requiring disposal First Aid Health System Health problems of the workers should be taken care of by providing basic health care facilities at the construction camp. All necessary first aid and medical facilities will be provided to the workers. The provision and maintenance of suitably equipped first aid facility throughout the extent of the works has to be borne by the contractor, who shall be responsible for all work and camp site welfare arrangements and requirements to the satisfaction of the Supervision Consultant and Site Engineer. The cost of the medical facilities will be part of the civil contract Training and Extension The training and extension programmes need to be conducted for Engineers of USISCL. These programmes should also be extended for the local population for their active participation in the project implementation. Apart from training, such programmes should include guidelines for safety, measures of disaster prevention, action required in case of Chapter - 9 Page 110

361 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand emergency, fire protection, environmental risk analysis etc. The cost involved for such a programme is presented in Table 9.3. TABLE 9.3 COST OF ENVIRONMENTAL TRAINING PROGRAMMES S NO. ITEM COST (`) 1 Curriculum Development and Course Preparation; 3 Rs per month 90, Extension Officer for 1 year Rs15000 per month 3,60,000 3 Demonstration/presentation aids 80,000 4 Transportation and Miscellaneous 70,000 TOTAL 6,00, Soil Erosion Control Careful planning for excavation, filling and dumping along with re-vegetation are required to mitigate the soil erosion. A general guideline to control soil erosion shall be to stop all the earthwork activities during rainy season so that surfaces having loose earth are not exposed to rains. The cutting and filling area, on completion of the work shall be dressed well, compacted and covered with plantation. Pasture / grass are proposed in airport area for soil erosion control Cultural Uplift Assistance The region has rich cultural heritage. During the construction and operation period of this project, construction workers and staff personnel will be staying at project site. The project will serve as a platform for cultural exchanges. The project will bring diverse cultural events and will lead to cultural uplift of the area. A provision of ` 5 lakhs has been provided in the estimate to maintain the cultural heritage/events and promote awareness, which should be appropriately utilised by cultural department of local administration OPERATION STAGE Air Pollution Control During Operation Phase, the major sources of air pollution are from DG sets, vehicular traffic and emissions from increased aircraft operation. Control measures to reduce the pollutant emissions from DG sets are as follows. Scrubber to be installed at the outlet of the DG sets. Good quality fuel with low sulphur content should be used. Periodic maintenance of DG sets as per defined schedule of manufacturer. Maintaining proper stack height. Chapter - 9 Page 111

362 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand The minimum stack height would be as per the CPCB standard (Emission Regulations Part IV: COINDS/26/ ) for DG set. As per the standard, minimum height of DG stack should be H = h P Where, H = height of the stack h = height of the building in which the DG set is installed P = the capacity of the DG set in KVA For 500 KVA rating DG set the stack height comes out to be 9.472m. By providing proper stack height, pollutant concentration can be reduced by proper dispersion of pollutants. Providing proper circulating place in the parking area and proper traffic management at the entry and exit places can reduce pollutant release from the vehicles. Various possible emission reduction measures that can be applied to aircraft operations are: Single/Reduced Engine Taxiing Derate Takeoff power Reduce use of reverse Thrust During operation it is proposed to use Ground Power Unit (GPU) in place of Auxiliary Power Unit (APU). This will facilitate less exhaust gases at airport Noise Control Measures Even though the frequency of aircrafts are very small (one flight per day), it is necessary to take an action to reduce the noise to acceptable limits at the nearby villages to the airport. In general, aircraft noise management measures are divided into two main procedures: Noise abatement procedures, and Noise mitigating procedures. Airport Noise Abatement Procedures: The noise abatement procedures are measures designed to reduce aircraft noise exposure from noise-sensitive land uses and population. Suggested noise reduction flight operational measures and noise reduction measures during parking at airports are discussed below. Noise Reduction Flight Operational Measures: When safety and weather permit, pilots should follow voluntary noise abatement guidelines that are designed to minimize the impact of aircraft noise from aircraft arriving at or departing from the airport. Noise reduction flight operational measures during landing and take-off operations are given in the following Table 9.4. Chapter - 9 Page 112

363 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand At Take Off At Landing TABLE 9.4 NOISE REDUCTION FLIGHT OPERATIONAL MEASURES Operational Measure Procedure Effect After reaching a certain altitude, Very effective Steepest Climb climb at maximum climb angle while maintaining normal climb power. Thrust cutback climb Reduced flap setting Delayed flap approach After reaching a certain altitude, reduce thrust to a lower noise level over noise sensitive areas, and reapply thrust and make a normal climb after passing over those areas. Landing is made with a shallow flap angle, used only where there is sufficient runway length. Ground noise level is reduced in proportion to thrust decrease due to reduction of aerodynamic drag. Daily timing of flap extension. Effect similar to the reduced flap setting procedures. 5 to 10dB(A) reduction in the case of B737 2 to 3 db(a) reduction 2 to 3 db(a) reduction Noise Reduction Measures during Parking at Airports: Efforts are being made to reduce aircraft noise during parking at airports by using Ground Power Units (GPUs) instead of APUs. The noise level of an APU is 85 to 98 db (A) for a B747, while a GPU can keep the noise level to within 55 to 59 db (A), which is lower than the background noise level. Noise Mitigating Procedures: The noise mitigating measures are measures designed to remedy significant noise exposure in existing noise-sensitive areas; and to minimize the development of noise-sensitive land uses within areas exposed to significant noise. An example of noise mitigation procedures is the installation of acoustic insulation in noisesensitive buildings such as dwellings, schools, temples and hospitals. Airport s authority should impose a mandatory noise abatement program, or to restrict access for older aircrafts which produces heavier noise. The program substantially reduces airport noise by requiring that all larger commercial aircraft (those weighing more than 75,000 pounds) meet more stringent noise reduction standards. During operation stage, there would be an instantaneous increase in the ambient noise levels due to operations of the aircraft. The period of noise increase will be very brief and temporary. ATR 42 type aircraft is proposed for the landing take off operations at the airport, which creates 40% lesser noise compared to other aircrafts. The proposed terminal block can be provided with sound absorbing material such as acoustic tile, carpets and drapes placed on ceiling floor or wall surfaces. The DG set room should be fitted with acoustic material and the generator should conform to the user guidelines specified by MoEF, placed in Annexure Water Supply and Waste Water Treatment Since the Airport is a commercial place, water is mainly used for domestic purpose like drinking, kitchens, bathrooms, toilets, and cleaning etc. After the completion of the project KL/day would be required for all the facilities. Out of the requirement, 4.2 KL/day would be required to meet passengers and officials demand; 6.85 KL/day would be Chapter - 9 Page 113

364 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand required for floor washing and 3.38 KL/day would be required for Horticulture. About 7.46 KL/day will be fresh water requirement which will come from municipal water supply. Total quantity of domestic waste water generation will be 9.9 KL/day. The generated waste water is collected and treated through packaged sewage treatment plant of 15 KL/day. After treatment, about 6.97 KL/day treated effluent will be used for floor washing & horticulture purpose. Flow Chart of the water requirement and re use after treatment in the airport is given in the Figure 9.1. FIGURE 9.1 FLOW DIAGRAM FOR WATER BALANCE Total Water Requirement (14.43 KLD) Fresh Water Requirement (4.2 KLD) Rooftop Water after Disinfection (3.26 KLD) Treated Water for Floor Washing & Horticulture (6.97 KLD) Passengers (2.80 KLD) Official &Staff (1.40 KLD) Floor Washing (6.85 KLD) Horticulture (3.38 KLD) Raw Sewage (9.95 KLD) Packaged Sewage Treatment Plant Treated Effluent (6.97 KLD) Solid Waste Disposal The project is estimated to generate about 6 kg of solid waste every day. Solid waste generated during the operation phase would be paper, cardboard, glass, metal, plastic containers, compostable foods, restaurant oil and grease, batteries, fluorescent lights, wood pallets, tires and electronics. Most of them are recyclable materials. Chapter - 9 Page 114

365 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand The various measures, which would be adopted towards collection and disposal of municipal solid waste at the airport, are Separate waste collection bins for recyclables placed next to garbage bins in all public areas, Recycling bins for glass, metal and plastics in eatable areas, Waste collection bins to collect compostable materials provided to all restaurant tenants, Desk side recycling bins in office areas, Extensive signage to educate travelling public and airport staff. The biodegradable and non-biodegradable waste shall be segregated during collection by using different colour bins for different type of waste. Every workstation shall be provided with such bins. In addition collection bins shall be provided at suitable locations in common place and open area for waste collection from floating population. The biodegradable as well as the non-biodegradable waste shall be transferred everyday to the larger bins kept outside the building at suitable place. To avoid odour and accumulation of fly-supporting materials, waste collection bins shall be washed at frequent intervals. The solid waste shall finally be transferred to Municipal facility for its treatment and disposal Horticulture/Natural Grass Turfing The greenbelt development/plantation in the airport area will not only function as landscape features resulting in harmonising and amalgamating the physical structures of proposed buildings with surrounding environment but will also acts as pollution sink/noise barrier. It will check soil erosion, make the ecosystem more diversified and functionally more stable, make the climate more conducive and restore balance. The entire land sites subject to use of construction related activities should be restored to the original setting by restoration and landscaping of the sites. Sites subject to excavation and tampering of ground profile shall be rectified and done by the Contractor before final closure of the construction activities. Landscaping of the areas within the premises of airport shall be taken up during construction period. Overall the project area shall be restored to the natural setting in an environmentally sound manner SUMMARY OF MITIGATION MEASURES Environmental mitigation measures have been incorporated within the design process, including the avoidance of potential impacts through alternative locations and other means. Appropriate measures have also been identified for action in the construction and operational phases. The general measures identified for all three phases are presented in Table 9.5. This table identifies the nature of the potential environmental impact, the measures, which have or shall be taken, the implementing agency and responsible organization. Chapter - 9 Page 115

No. Structure to be demolished Remarks in the existing boundary 1. Terminal building The building is an obstacle and needs to be removed. A new terminal building of smaller height and at a clear distance from runway is proposed. 2. Residential quarters Due to shortage of space in existing land boundary, the residential quarters cannot be accommodated, hence needs to be demolished. 3. Fire station building Due to shortage of space in existing land boundary, the Fire station cannot be accommodated, hence needs to be demolished. The Fire station will be built at new location inside the boundary 4. Car Park Due to shortage of space in existing land boundary, the car park cannot be accommodated, hence needs to be demolished. The Fire station will be built at new location inside the boundary 5. 2 Nos. RCC Box culverts There are three culverts crossing the runway at chainages 1038, 1397, 1492m from 14 end of the runway. These culverts were constructed about 20 years back. Out of these 3 culverts, 2 culverts are RCC box culvert and 1 culvert is a pipe culvert. These culverts were constructed when the runway was designed for Dornier aircraft of wt Kg. The present runway is being designed for ATR 42 aircraft of wt Kg. As there is no drawing available to check the strength of existing culvert for its suitability to carry wt. of 18,600 Kg, it is proposed to dismantle the 2 RCC box culverts and construct new RCC culverts at same locations as these locations are at natural flow of water.

392 EIA studies for expansion and strengthening of runway and up-gradation of associated operational infrastructure and terminal facilities at Naini-Saini Airport, Pithoragarh in Uttarakhand Annexure 9.3 STANDARDS/ GUIDELINES FOR CONTROL OF NOISE POLLUTION FROM STATIONARY DIESEL GENERATOR (DG) SETS (A) Noise Standards for DG sets ( KVA) The total sound power level, Lw, of a DG set should be less than, log 10 (KVA), db (A), at the manufacturing stage, where, KVA is the nominal power rating of a DG set. This level should fall by 5 db (A) every five years, till 2007, i.e. in 2002 and then in (B) Mandatory acoustic enclosure/ acoustic treatment of room for stationary DG sets (5 KVA and above) Noise from the DG set should be controlled by providing an acoustic enclosure or by treating the room acoustically. The acoustic enclosure/ acoustic treatment of the room should be designed for minimum 25 db (A) insertion loss or for meeting the ambient noise standards, whichever is on the higher side (if the actual ambient noise is on the higher side, it may not be possible to check the performance of the acoustic enclosure/ acoustic treatment. Under such circumstances the performance may be checked for noise reduction upto actual ambient noise level, preferably, in the night time). The measurement or insertion loss may be done at different points at 0.5 m from the acoustic enclosure room, and then averaged. The DG set should also be provided with proper exhaust muffler with insertion loss of minimum 25 db (A). (C) Guidelines for the manufacturer/ users of DG sets (5KVA and above) 1. The manufacturer should offer to the user a standard acoustic enclosure of 25 db (A) insertion loss and also a suitable exhaust muffler, with insertion loss of 25 db(a). 2. The user should make efforts to bring down the noise levels due to the DG set, outside his premises, within the ambient noise requirements by proper sitting and control measures. 3. The manufacturer should furnish noise power levels of the un-silenced DG sets as per standards prescribed under (A). 4. The total sound power level of a DG set, at the user s end, shall be within 2 db (A) of the total sound power level of the DG set, at the manufacturing stage as prescribed under (A). 5. Installation of a DG set must be strictly in compliance with the recommendations of the DG set manufacture. 6. A proper routine and preventive maintenance procedure for the DG set should be set and followed in consultation with the DG set manufacturer which would help prevent noise levels of the DG set from deteriorating with use.
