12 Promoter : IDENTIFICATION, PREDICTION AND EVALUATION OF IMPACTS Environmental impact can be defined as any alteration of environmental conditions, adverse or beneficial, caused or induced by the action or set of actions under consideration. Various operations involved in the project have been studied in details to identify, predict and evaluate impacts on various environmental components. The identified impacts were quantified using mathematical models to a possible extent so as to estimate the future environmental scenario. AIR ENVIRONMENT Air pollution has long been recognized as a brain storming issue worldwide. The onset of technological and scientific innovations in various fields and diverse activities of human race for its elegance have put extra load on the atmosphere by way of releasing air pollutants like particulate matter (PM 10, PM 2.5 ), sulphur dioxide (SO 2 ), oxides of nitrogen (NO X ), carbon monoxide (CO), unburned hydrocarbon (HC) and other organic as well as inorganic pollutants including trace metals responsible for causing health consequences. Entry of pollutants into the atmosphere occurs in the form of gases or particles. Continuous mixing, transformation and transboundary transportation of air pollutants make air quality of a locality unpredictable. The growth of population, industry and number of vehicles and make the problem of air pollution still worse. Rapid industrialization and vehicular traffic especially in the urban areas of India is a great threat to air quality.

Low-sulphur-content fuel (HSD - Sulphur content 0.05%) will be used. Vehicular exhausts Sufficient width of driveways to ensure smooth traffic movements. especially congestions during peak traffic hours. Provisions of fully internalized parking including the parking facilities for the visitors. Guided traffic ways within the project site. Speed humps will be installed for speed restrictions inside the project area. WATER ENVIRONMENT:- CONSTRUCTION PHASE: WATER CONSERVATION TECHNIQUES: Best construction practices will be adopted to reduce the water demand for construction activities: Use of curing water: Spraying of curing water and after liberal curing, all concrete structures will be covered with gunny bags, followed by spraying of water. Use of polymer dispersion and air entraining agents to reduce the construction water demand. Admixtures will be used to reduce water demand during construction. Discouraging the washing of vehicles and equipment on the construction site. Workers will not allow to wash their personal vehicles on site. Vehicles and equipment that regularly leave the construction site should be washed offsite. MANAGEMENT PLAN: SOURCES Generation of sewerage MANAGEMENT Temporary septic tank followed by soak-pit will be provided. Un-captured run-off The rain-water entering into the pit will be screened for the removal of from the site may heavy silt and other materials. contaminate water aquifers. ground Provisions will be made to ensure the construction vehicles stick to the access track to prevent mud & dirt being deposited on roads.

17 Promoter : Fence will be constructed around the site to trap sediments whilst allowing the water to flow through. Up slope water will be diverted with turf and due care will be taken not to mix mortar in locations that will drain into storm water system. Unsanitary conditions The civil contractor will be made responsible for site sanitation and will during rainy season. be bound by the management to adhere to healthy level of sanitation. There will be no stagnant water at site, as the runoff from the relevant areas will be systematically drained into the storm water line. There will be provision of cleaning the storm water line periodically. POST CONSTRUCTION PHASE: Daily water demand will be 444 KLD (fresh: 210 KLD + recycled: 234 KLD). The fresh water demand will be met from Ground water supply. A. WATER CONSERVATION TECHNIQUES: Following water conservation techniques have been proposed for the project: Dual plumbing system will be adopted to utilize the treated waste water for flushing (94KLD), landscaping and general washing (140 KLD). This will help in reducing the fresh water demand by 52%. Dual flushing fixtures will be used to allow different volumes of water for solid and liquid flushing which will help in conserving the water demand for flushing significantly. Water meters will be installed for the following: o Potable water consumption o Landscape water consumption o Hot water consumption through solar systems, at building level o Treated waste water consumption Landscape design & management of irrigation systems: o Native & xeriscaping plant species: Choose native plant species that need less water.

18 Promoter : o Creating Hydrozones: Grouping of plant according to their water needs to provide adequate water to all plants without over or under-watering. o Maintain Healthy Soil: Healthy soils are the basis for a water-smart landscape; they effectively cycle nutrients, minimize runoff, retain water, and absorb excess nutrients, sediments, and pollutants. o Mulching: Incorporate mulch around shrubs and garden plants to help reduce evaporation, inhibit weed growth, moderate soil temperature, and prevent erosion. Adding organic matter and aerating soil can improve its ability to hold water. o Avoid watering during the heat of the day. Water early in the morning to reduce the evaporation rate o Drought tolerant species will be selected. o Turfs will be avoided to the extent possible. o Central shut off valve will be provided o Sprinkler landscaping system will be used to conserve water B. WASTE WATER GENERATION AND TREATMENT: Approximate 262 KLD waste water will be generated which will be treated in STP of capacity 300 KLD, based on MBBR technology. Physico chemical characteristics of influent and effluent are given as: Parameters Influent (mg/ltr) Treated effluent (mg/ltr) BOD mg/l < 5 mg/l COD mg/l < 30 mg/l ph Oil & Grease < 5 mg/l TSS mg/l < 10 mg/l PROCESS DESCRIPTION: OPERATING PRINCIPLE: MBBR Technology is a combination of activated sludge process (suspended growth) and bio filter processes (attached growth). Moving Bed Biofilm Bioreactor (MBBR) process uses the whole tank volume for biomass growth. It uses simple floating media, which are carriers for attached growth of biofilms. Biofilm carrier movement is caused by the agitation of air bubbles.

19 Promoter : This compact treatment system is effective in removal of BOD as well as nitrogen and phosphorus while facilitating effective solids separation. In order to conserve water, Sewage Treatment Plant has been designed to ensure that treated effluent characteristics are well below the permissible limits of local/national pollution control norms even under varying flow conditions which are typical for such systems. This implies that the selected process shall be able to withstand the shock load situation. We propose to use MBBR treatment Technology for STP. This has the following advantages: The process has long retention time and can absorb shock load situation. The process produces a well-oxidized sludge in small quantities only, which can be removed and used as manure. PROCESS DESCRIPTION: Sewage generated from various sources after passing through an oil & grease trap will be carried through battery of manholes inter connected through soil pipes under gravity flow and will be collected in the collection cum equalization tank after passing through screen chambers near the STP. Manually cleaned bar screens will be installed in the screen chamber to screen of any large pieces. Coarse bubble aeration system will be provided to keep the sewage in homogeneous condition. From the Collection cum Equalization Tank, the waste water will be pumped via two submersible solids handling pumps (1 working + 1 standby) into adjoining aeration tank. In the aeration tank waste water will be mixed with micro-organisms in presence of dissolved oxygen. Micro-organisms will assimilate organic impurities. The mixed liquor suspended solids (MLSS) will be maintained at levels of 3,000 mg/l 4,000 mg/l. The bottom of the aeration tank will be covered with submerged air diffusers. Submerged air diffusers will provide mixing and oxygen for the needs of micro-organisms. Compressed air will be supplied through two common air blowers (1 working + 1 standby) for collection cum equalization tank, aeration tank & sludge holding tank.

20 Promoter : From the aeration tank mixed liquor will flow by gravity into adjoining clarifier tank (Secondary settling tank). The solids will settle in the clarifier tank. Sludge Recirculation pumps will pump the settled sludge from the bottom of clarifier tank to sludge holding tank and the aeration tank for maintaining desired MLSS level.overflow weir with scum baffle will be provided in the clarifiers to take treated waste water out of the clarifier. From the clarifier, treated waste water will flow via gravity into adjoining treated effluent cum filter feed tank. Treated waste water after treated effluent cum Filter Feed tank will be clear, odorless, low BOD and low suspended solids. For improving the treated waste water quality, treated waste water after Filter Feed tank will be passed through Pressure Sand Filter followed by Activated Carbon Filter for further reduction of Suspended Solids, BOD, COD, etc. so as to make it suitable for Irrigation purpose process. Water will be passed through U/F feed & backwash pump, cartridge filter, U/F membrane for further reduction of suspended solid, BOD, COD etc as to make it suitable for flushing purpose. The treated effluent will be collected/stored in the flushing permeate storage tank from where it can be used for flushing, horticulture and other requirements.

Oil & Grease Roads, driveways, parking lots etc. Oil & Grease trap will be provided to remove oil & grease, suspended matter, and ensure the quality of water. Storm water control and rain water harvesting will be done as per the standards laid down by CGWA & BIS. Following measure will be adopted for the same: Construction Sequencing: Construction sequencing (involves disturbing only part of a site at a time to prevent erosion from dormant parts) has been done at site. Grading activities and construction are completed and soils are effectively stabilized on one part of the site before grading and construction commence at another part. Compost Blankets: A compost blanket is a layer of loosely applied composted material placed on the soil in disturbed areas to reduce storm water runoff and erosion. This material fills in small rills and voids to limit channelized flow, provides a more permeable surface to facilitate storm water infiltration, and promotes re-vegetation. Post Construction Phase: a. Design: For good design of rainwater harvesting, following points are to be kept under consideration: Ideal location with good ground slope.

27 Promoter : The location has adequate subsurface permeability of the aquifer to accommodate maximum recharge of rainwater through injection well. Rate of filtration should exceed average rainfall intensity. Clogging of filtration media should be cleaned periodically. Ground water pollution does not take place. b.

Lift load can be reduced by 23% by use of VF drives. All capacitors will be provided with Harmonic Filters to avoid distortion in Voltage. Automatic Power Factor correction panel with capacitor will be used for Common Load & Fixed Capacitor for Transformer to minimize the losses. Insulation of exposed walls and roof will be done to minimize heat gains inside the building. This will help to reduce the air conditioning demand of the buildings. Emphasis will be given on low maintenance, low wattage and longer life in selection of chokes and lamps for all common area and external light fixtures. RISK & HAZARD IN CONSTRUCTION INDUSTRY: The International Labour Organization (ILO) classifies the construction industry as government and private-sector firms erecting buildings for habitation or for commercial purposes and public works such as roads, bridges, tunnels, dams or airports. In India, construction workers also clean hazardous waste sites.

33 Promoter : Health Hazards On Construction Sites Construction workers are exposed to a wide variety of health hazards on the job. Exposure differs from trade to trade, from job to job, by the day, even by the hour. Exposure to any one hazard is typically intermittent and of short duration, but is likely to reoccur. A worker may not only encounter the primary hazards of his or her own job, but may also be exposed as a bystander to hazards produced by those who work nearby or upwind. This pattern of exposure is a consequence of having many employers with jobs of relatively short duration and working alongside workers in other trades that generate other hazards. The severity of each hazard depends on the concentration and duration of exposure for that particular job. Bystander exposures can be approximated if one knows the trade of workers nearby. Hazards present for workers in particular trades are listed in table. Primary Hazards Encountered In Skilled Construction Trades Each trade is listed below with an indication of the primary hazards to which a worker in that trade might be exposed. Exposure may occur to either supervisors or to wage earners. The classifications of construction trades used here are those used in India. It includes the construction trades as classified in the Standard Occupational Classification system. This system classifies the trades by the principal skills inherent in the trade.

Chemical Hazards 2. Physical Hazards 3. Biological Hazards Evaluating Exposure Evaluating either primary or bystander exposure requires knowing the tasks being done and the composition of ingredients and by-products associated with each job or task. This knowledge

35 Promoter : usually exists somewhere (e.g., material safety data sheets, MSDSs) but may not be available at the job site. With continually evolving computer and communications technology, it is relatively easy to obtain such information and make it available. Management For Safe Construction Work Effective safety programmes have several features in common. They are manifest throughout organizations, from the highest offices of a general contractor to project managers, supervisors, union officials and workers on the job. Codes of practice are conscientiously implemented and evaluated. Costs of injury and illness are calculated and performance is measured; those that do well are rewarded, those that do not are penalized. Safety is an integral part of contracts and subcontracts. Everybody-managers, supervisors and workers-receives general, site-specific and site-relevant training. Inexperienced workers receive on-the-job training from experienced workers. In projects where such measures are implemented, injury rates are significantly lower than on otherwise comparable sites. Preventing Accidents And Injuries Entities in the industry with lower injury rates share several common characteristics: they have a clearly defined policy statement that applies throughout the organization, from top management to the project site. This policy statement refers to a specific code of practice that describes, in detail, the hazards and their control for the pertinent occupations and tasks at a site. Responsibilities are clearly assigned and standards of performance are stated. Failures to meet these standards are investigated and penalties imposed as appropriate. Meeting or exceeding standards is rewarded. An accounting system is used that shows the costs of each injury or accident and the benefits of injury prevention. Employees or their representatives are involved in establishing and administering a programme of injury prevention. Involvement often occurs in the formation of a joint labour or worker management committee. Physical examinations are performed to determine workers fitness for duty and job assignment. Hazards are identified, analysed and controlled following the classes of hazards. The entire work site is inspected on a regular basis and results are recorded. Equipment is inspected to ensure its safe operation (e.g., brakes on vehicles, alarms, guards and so on). Injury hazards include those

36 Promoter : associated with the most common types of lost-time injuries: falls from heights or at the same level, lifting or other forms of manual materials handling, risk of electrocution, risk of injury associated with either highway or off-road vehicles, trench cave-ins and others. Health hazards would include airborne particles (such as silica, asbestos, synthetic vitreous fibres, diesel particulates), gases and vapours (such as carbon monoxide, solvent vapour, engine exhaust), physical hazards (such as noise, heat, hyperbaric pressure) and others, such as stress. Preparations are made for emergency situations and emergency drills are conducted as needed. Preparations would include assignment of responsibilities, provision of first aid and immediate medical attention at the site, communication at the site and with others off the site (such as ambulances, family members, home offices and labour unions), transportation, designation of health care facilities, securing and stabilizing the environment where the emergency occurred, identifying witnesses and documenting events. As needed, emergency preparedness would also cover means of escape from an uncontrolled hazard such as fire or flood. Accidents and injuries are investigated and recorded. The purpose of reports is to identify causes that could have been controlled so that, in the future, similar occurrences can be prevented. Reports should be organized with a standardized record-keeping system to better facilitate analysis and prevention. To facilitate comparison of injury rates from one situation to another, it is useful to identify the pertinent population of workers within which an injury occurred, and their hours worked, in order to calculate an injury rate (i.e., the number of injuries per hour worked or the number of hours worked between injuries). Workers and supervisors receive training and education in safety. This education consists of teaching general principles of safety and health, is integrated into task training, is specific for each work site and covers procedures to follow in the event of an accident or injury. Education and training for workers and supervisors is an essential part of any effort to prevent injuries and disease. Training about safe work practices and procedures have been provided by some companies and trade unions. These procedures, include lockout and tagout of electrical power sources during maintenance procedures, use of lanyards while working at heights, shoring trenches, providing safe walking surfaces and so on. It is also important to provide site-specific training, covering unique features about the job site such as means of entry and exit. Training should include instruction

37 Promoter : about dangerous substances. Performance or hands-on training, demonstrating that one knows safe practices, is much better. Information about chemical, physical and other health hazards is available at the work site in the languages that workers use. If workers are to work intelligently on the job, they should have the information necessary to decide what to do in specific situations. And finally, contracts between contractors and subcontractors should include safety features. Provisions could include establishing a unified safety organization at multi-employer work sites, performance requirements and rewards and penalties. LIGHTING PROTECTION: The structures shall be protected against lightning in accordance with the requirement of IS 2309: 1989 with latest amendments. The risk factor requires provision of lightning protection and in addition considered necessary for the safety of tall buildings and human life. The lightning protection system shall comprise of a grid of horizontal air terminations and vertical finials provided at the terrace of each high rise tower at the highest point and that of the low rise buildings which are not within the protective angles of the high rise terminations. The horizontal & vertical air terminations shall be connected through a series of down earth conductors running along the sides of the building with earth tapes to the Pipe type earth electrodes / earth stations. Earth test points shall be provided. The lightning protection system shall be based on use of hot dip galvanized iron i.e. GI strip conductors and GI earth stations. OR Alternatively, controlled steamer emission system along with chemical earth pits may be employed, if client prefers so, but this system of lightning protection shall not be as per IS codes. All towers shall be protected from lightning by providing Controlled streamer emission (CSE) lightning arrestors installed at the highest point at the terrace level duly connected to GI tape/cable as per system design criteria.

38 Promoter : FIRE PROTECTION Preventing fire ignition is the first line of defense in fire safety. The second line of defense, if ignition does occur, is to manage the fire s impact and minimize the risk. The two main methods for managing the impact of a fire are Manage the People Exposed and Manage the Fire itself. The automatic fire alarm shall be provided depending on the height of the tower. It shall be as follows: Group A, sub division A-4 (Apartment Houses): Above 45m but not exceeding 60 m in height, minimum fire fighting requirement (as per NBC 2016 Part IV Table 7) will be provided in the project. S. No. Description Minimum Fire Fighting Requirement 1. Fire extinguisher Required 2. First Aid Hose reel Required 3. Wet riser Required 4. Down comer Not Required 5. Yard hydrant Required 6. Automatic sprinkler system Required 7. Manually operated electronic fire alarm system Required 8. Automatic detection & alarm system Not Required 9. Underground water tank 1,50,000 L 10. Terrace water tank 10,000L FIRE DETECTION Despite the many precautions taken, fires may breakout. Hence the project will establish measures to detect a fire and to extinguish it. Automatic fire detection has many advantages such as speed and reliability and is recommended. MANAGEMENT PLAN Since the project may face fire hazards or other emergency situations; an emergency plan is provided to caution the persons during any accidents. The fundamental approach, governing fire

39 Promoter : safety attempts to ensure that fires do not at all start in the first place and should they occur, to restrain their spread by quick detection and extinguishments. The task of accident and emergency control can be simplified and made effective if pre-planned systems and procedures are available. Without these, important matters may be overlooked at the time of an emergency. Every management must survey the total operation to identify potential for fire losses and develop an action plan to put the business back to normal with minimum loss of time. A fire protection Manual should be prepared, preferably in 3-parts. 1. The first part should outline the fire risks in terms of plant locations, equipment and facilities and indicate the ways in which risks have been minimized. 2. The second part would set out operating procedures, standards of fire protection established, and maintenances of these standards action to be taken in the event of fire by every level of management responsibility for inspection and repair. It should also include instructions for staff responsible for building services. 3. The third part should outline the training required for existing and new staff, the inspection schedules and check lists, sources of additional information and help. The Management Cell of the project shall keep ready a plan to alert and take care of residents in case there is any fire. There shall be designated an Emergency Team that shall consist of staff of maintenance department, security supervisor representative of residents from campus. ELECTRICAL HAZARDS SAFETY MEASURE PLAN A dangerous condition such that contact or equipment failure can result in Electric shock, arc-flash burn, thermal burn, or blast. Electrical hazard includes dangerous meaning able or likely to inflict injury ; there are high voltage, low current sources that are not intrinsically dangerous, and there are low-voltage, high-current sources that are not safe. A harmless static electricity shock could cause sufficient startle reaction to make a worker fall off a ladder. A hazard analysis is necessary to identify electrical hazards and determine the degree of risk. We are considering different types of measures for preventing electrical hazards which are as follows:
