1 1. INTRODUCTION EXECUTIVE SUMMARY TANGEDCO established 3 x 210 MW North Chennai Thermal Power Station Stage-I and 2 x 600 MW Stage-II in NCTPS Complex at Ennore and Puzhudivakkam Villages, Ponneri Taluk, Thiruvallur District in Tamil Nadu. The Stage-I Plant was commissioned during 1995 and Stage II was commissioned in An area of 190 acres of barren land is available within the existing NCTPS. In order to offset the power demand of Tamilnadu, TANGEDCO has proposed to set up a coal based 1 x 800 MW super critical thermal power plant, Stage III within the North Chennai Thermal Power Station (NCTPS) complex using the existing infra structure facilities viz., Cooling water channel/coal conveyors of NCTPS. The sea water for cooling water requirement for the NCTPS Stage-I is drawn from the Ennore Port Basin located adjacent to the NCTPS Complex, through an intake channel. Another channel was constructed to draw cooling water for the requirement of NCTPS Stage-II and TANGEDCO s proposed Ennore SEZ Thermal Power Project which is located near the NCTPS Complex. The drawal capacity of this channel is 65 cumec. After the drawal of Cooling water for NCTPS stage II TPP (2x600 MW) and Ennore SEZ TPP (2x800 MW), around 10 cumec is available. This balance quantity is proposed for the cooling water requirement of NCTPS stage III TPP adopting Natural Draft cooling tower system. Desalination plant will be established to obtain raw water for the plant purposes. 100% Imported Coal from Indonesia will be transported through pipe conveyor from proposed Coal Berth 3 of Ennore Port. Hence there is no land acquisition/right of Way (ROW) for Coal conveyor/cooling water system. The proposed project falls under Project/ Activity 1(d) Thermal Power Plants and Category A 500 MW (Coal/ Lignite/ Naphtha & gas based) project under the schedule as per EIA notification issued on 14th September, 2006 and hence the project requires Environmental Clearance from MoEF, Govt of India.

7 3.6 Man power Requirement The man power required for the project will be sourced from nearby areas to the maximum extent. In the construction period 175 persons are required and 550 persons are required in operation & Maintenance. 4. BASELINE ENVIRONMENTAL STATUS Meteorology (Climate) Weather data was collected for a period of June to August 2012 and analyzed. The predominant wind direction during the study period was from WSW direction closely followed by W & SW. The average maximum temperature is C and minimum is C. Humidity is very high and rises to about 100 percent and lowest up to 29 percent. Ambient Air Quality The ambient air quality was monitored at 11 locations within 15Km of the project site as per MoEF guidelines. The study area represents mostly rural and semi urban environment. Air pollutants like Particulate Matter (PM), Sulfur dioxide (SO 2 ), Oxides of Nitrogen (NO X ), Ozone (O 3 ), and Mercury (Hg) were identified for representing the baseline status of the ambient air quality within the study area. The observed air pollutants were within the standard limits as per CPCB limits. AAQ levels recorded are given in below Table: 8. Table: 8 Ambient Air Quality levels in the study area- µg/m3 S.No Parameter Min Max CPCB, Limits 1 SPM * 2 PM 2.5µ RPM 3 PM 10µ SO NO x O Hg BDL BDL ---* Note:* No standards are given for SPM & Hg in the Revised NAAQ standards.

8 Water Quality Status Surface water (3 no) and ground water samples (9 no) were collected from different sources within the study area and some important physical and chemical parameters including heavy metals were considered for depicting the baseline status of the study area. Surface Water Quality Observations The ph of water samples varied from 8.11 to 8.68 The Total Dissolved Solids are in the range of 6784 mg/l to mg/l. The Total Hardness values are in the range of 1960 mg/l to mg/l The chloride values are in the ranges of 3229 mg/l to mg/l. The fluoride values are in the rage of 0.22 mg/l to 1 mg/l. Ground Water Quality Observations The ph of water samples varied from 6.6 to 7.9 The Total Dissolved Solids are in the range of 202 mg/l to 4654 mg/l. The Total Hardness values are in the range of 137 mg/l to 3312 mg/l The chloride values are in the ranges of 25 mg/l to 1450 mg/l. The fluoride values are in the rage of 0.30 mg/l to 0.85 mg/l. Noise Quality Noise levels are monitored at 10 Locations in the study area. The main sources of noise in the study area are domestic activities, industrial activities and vehicular traffic. The main occupation of the villagers in the study area is agriculture and business. The noise levels observed in some of the rural areas are primarily owing to vehicular traffic and other anthropogenic activities. In rural areas, wind blowing and chirping of birds would contribute to noise levels especially during the nights. The day equivalents during the study period are ranging between 52.9 to 71.6 db (A) and whereas the night equivalents were in the range of 41.8 to 58.9 db (A). From the results it can be seen that the Day equivalents and the Night equivalents were within the Ambient Noise standards of residential and commercial areas standards. The day equivalent and night equivalent noise levels found at the plant site were 59.2 db (A) and 49.7 db (A) respectively which were within the industrial noise standards. Soil Quality Soil Samples were collected from 8 locations from the study area. The ph of the soil is an important property; plants cannot grow in low and high ph value soils. The normal range of the soils in 6.0 to 8.5 is called as normal to saline soils. The soils having ph below 7 are considered to be acidic from the practical standpoint, those with ph less than 5.5 and which respond to liming may be considered to qualify to be Ramky Enviro Engineers Ltd., Hyderabad E-8

9 designated as acid soils. On the basis of ph measurements, the degree of soil acidity may be indicated. The ph values in the study area are varying from 7.33 to 8.30 indicating that the soils are falling in normal to saline class. Flora & Fauna There are no endangered or endemic species of flora and fauna in core and buffer zone of the proposed project. Environmental sensitive areas Study was carried out to identify environmental sensitive areas within 15 Km peripheral of the project site and found that there are no Sanctuary, Elephant/Tiger reserve (existing as well as proposed), migratory roots within 15 Km of the project site. Sl. No. Features Existence with in 15 Km of the project site 1 Sanctuary Nil 2 Elephant/ Tiger reserve Nil 3 Migratory routes Nil 5. ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES The impacts due to proposed plant on the environment are classified into two phases and possible impacts are assessed. During Construction phase During Operation phase a) Impacts during construction phase: The possible construction activities that contribute to the environmental impacts are: Dust Generation during leveling of earth Dust generation due to the movement of vehicles on unpaved roads Emission of pollutants from vehicular exhaust Unloading of raw materials and removal of unwanted waste material from site Accumulation of excavated earth material The impact of the above activities would be temporary and will be confined within the project boundary. Overall, there will not be any adverse impact on the surroundings during the construction period. b) Impacts during Operation Phase Impact on Air Quality The proposed project is a coal based thermal power plant and the major source of pollution would be the emissions from the stack. The ash content in the raw coal is considered 12% in Imported coal for prediction of air emissions. The important air Ramky Enviro Engineers Ltd., Hyderabad E-9

10 pollutants generated from the thermal power plant are particulate matter (PM), sulphur di-oxide (SO 2 ), and oxides of nitrogen (NO X ). The major air pollutants generated from the proposed thermal power plant are given below: 1. Dust particulates in flue gas from chimney 2. SO 2 and NO X in flue gas 3. Coal dust particles due to handling of coal 4. Fly ash dust particles from ash silos and ash disposal area 5. Coal dust generated at the conveyor transfer points 6. Fly ash vented out during the unloading of fly ash from ESP hoppers to silos As the proposed plant NCTPS Stage III (1x800 MW) is located within NCTPS Complex consists of NCTPS Stage I (3x210 MW), NCTPS Stage II (2x600 MW) and surrounded by proposed new power plants, the stack emission details of all proposed Thermal power plants are given in Table 9 are considered for modelling for prediction of cumulative impacts. The future predicted ground level concentrations based on only proposed project are given in Table 10 and where cumulative future predicted impacts are given in Table 11. The post project pollution levels are found to be within the CPCB limits.

12 The wastewater from plant will be collected and treated in conventional effluent treatment plant. The treated effluent will be reused and impact on natural sources would be negligible. Cooling Tower Blow down and Rejects from Desalination plant: The cooling tower blow down from the proposed plant along with rejects from Desalination plant will be discharged in to sea through the existing pre cooling channel of NCTPS. Comprehensive Marine study: The Comprehensive Marine EIA Study was carried out by M/s WAPCOS, a Govt of India untertaking for one year to identify the impacts of outfall of the proposed Ennore SEZ TPP (2x800 MW) and NCTPS stage III (1x800 MW) Thermal Power projects in addition to the existing NCTPS Stage I (3x210 MW) & Stage II( 2x600 MW) and Vallur TPP (3x500 MW) in the NCTPS Complex on marine environment. The conclusions of the study are as follows: Based on the modelling study carried out by IIT,Madras, the temperature of outfall with 3,20,000 cu.m/hr discharge will be at about 3.3 o C higher than ambient conditions. This temperature further reduces to about C, ie., almost reaches ambient temperature at a distance of 2.0 km from the outfall. Hence there will be marginal / insignificant impact. The present creek dilutes and disperses the outfall water temperature well as there is good tidal exchange between Ennore creek and sea, which indicates a positive effect of the total discharges in the pre-cooling channel. The average salinity differential of the discharges from closed cycle discharges of NCTPP Stage III TPP, Vallur TPP and Ennore SEZ TPP is g/l. However, when all the discharges get mixed with 3,00,000 cu.m /hr quantity of open cycle water discharges from NCTPS Stage I &II, the outfall discharge will have a salinity differential of only 1.53g/l. Hence, the present outfall which will have highly diluted discharge will have marginal / insignificant impacts. The project area has biological features characteristics of any normal coastal area in the occurance, abundance and bio diversity of biological community of phytoplankton, zooplankton, benthos and fishes. The area is devoid of mangrove vegetation, Seaweeds and coral reefs. No rare, endangered, threatened marine species were recorded. The marine water quality and ecology in and around the proposed outfall area is that of any normal coastal environment during the study period. In view of the above, it is concluded that the outfall of the proposed NCTPS stage III Thermal Power projects in the NCTPS Complex would not change the quality of existing natural coastal environment.

13 Ash Utilization plan Fly ash and bottom ash would be collected and stored in the silos and given to end users for manufacturing cement and bricks. TANGEDCO would put maximum efforts and ensure bottom ash utilization. 100% ash utilization will be achieved as per MoE&F new notification dated in the phased manner as follows. S.No Fly ash utilization level Target date 1. At least 50% of fly ash generation One year from the date of commissioning 2. At least 70% of fly ash generation Two years from the date of commissioning 3. 90% of fly ash generation Three years from the date of commissioning % of fly ash generation Four years from the date of commissioning Impact on Health Adequate air, water and noise pollution control measures will be provided in the proposed project site units to conform to regulatory standards. The environmental management and emergency preparedness plans are proposed to ensure that the probability of undesired events and consequences are greatly reduced, and adequate mitigation is provided in case of an emergency. The overall impact on Human health would be negligible during operation of power plant. 6. ENVIRONMENTAL MONITORING PROGRAM Environmental Monitoring Program has been designed for assessing the efficiency of implementation of Environment Management Plan and to take corrective measures in case of any degradation in the surrounding environment. Different activities involved in the proposed project and their impact on various environmental attributes have been taken into account while designing a detailed environmental monitoring program. Implementation of EMP and periodic monitoring is proposed to be carried out at plant level and area level for the proposed thermal power plant and allied activities like coal handling facilities, workshop, colony, etc. A comprehensive monitoring mechanism has been devised for monitoring of impacts due to proposed project. Plant level environmental protection measures like dust suppression, treatment and recycling of wastewater, plantation and noise control in the plant premises, housekeeping, implementation of EMP and Environmental Clearance conditions will be monitored by the plant authorities.

14 7. PROJECT BENEFITS The proposed project with a massive investment of Rs Crores will improve the physical and social infrastructure of the area as the proposed project is a mega project. As the proposed project being adopted supercritical technology the unit leads to enhanced plant efficiency, less fuel consumption and reduced green house emissions. TANGEDCO will provide Budget allocation of Rs.8.00 Crores as capital expenditure and 2.00 Crores as annual recurring expenditure for Corporate Social Responsibility (CSR) activities. The need based assessment study (socio Economic study) of the surrounding villages was carried out by the Madras school of social works, Chennai. The physical infrastructure and socio-economic status of the surrounding areas will be benefited as follows: Road transport facilities which improve accessibility Improvement in education, housing, and banking facilities Improvement in postal & communication services Recreation facilities Improvement in power supply, water supply and sanitation Improvement in economic conditions Improvement in the employment potential within the plant Increase in revenue to the state in the form of taxes and duties from the development of local businesses 8. ENVIRONMENTAL MANAGEMENT PLAN The Environmental Management Plan (EMP) is required to ensure sustainable development of the plant area. The EMP will be integrated in all the major activities of the project with clearly defined policies to ensure that the ecological balance of the area is maintained and the adverse effects are minimized. EMP requires multidisciplinary approach with mitigation, management, monitoring and institutional measures to be taken during implementation and operation, to eliminate adverse environmental impacts or reduce them to acceptable levels. In order to ensure sustainable development in the study area; it needs to be an all encompassing plan for which the plant authorities, government, regulating agencies and the population of the study area need to extend their cooperation and contribution. The mitigation measures are planned for construction and operation phases and the overall management plan helps to improve the supportive capacity of the receiving bodies. The EMP aims to control pollution at the source level to the possible extent with the available and affordable technology followed by the standard treatments Ramky Enviro Engineers Ltd., Hyderabad E-14

15 before getting discharged. The recommended mitigation measures will synchronize the economic development of the study area with the environmental protection of the region. Environmental protection measures like monitoring & management, dust suppression, treatment & re-use of wastewater, plantation and noise control within the project area will be looked after by the project level management. 9. BUDGETARY PROVISIONS FOR EMP In order to comply with the environmental protection measures as suggested in the above sections, the management has made a budgetary provision for Environmental Protection and Safety measures.
