The detailed discussion of baseline study is addressed in chapter - 2 of conceptual plan.
1.8 WATER REQUIREMENT
The total water requirement during operation is 112 KLD. Source of water is from CMWSSB. The wastewater generation from the project is estimated to be about 93, which will be treated in the proposed grey water treatment of 45 KLD out and STP of 55 KLD. The outlet from the grey water treatment will be used for flushing and gardening. The treated water from the STP will be used for roadside avenue plantation. The estimation of water requirement and the water balance chart is shown in Table 5 and 6.

2. ENVIRONMENTAL IMPACT ASSESSMENT
2.1 INTRODUCTION
This chapter presents the assessment of various impacts due to construction of Multi storied residential building at Vepery, Purasawalkam, Chennai district in the state of Tamil Nadu. Generally, the environmental impacts can be categorized as either primary or secondary. Primary impacts are those, which are attributed directly by the project and secondary impacts are those, which are indirectly induced and typically include the changed patterns of social and economic activities by the proposed project. The Proposed construction project would create impact on the environment in two distinct phases:
➢ Impacts during the construction phase
➢ Impacts during the operation phase
The construction and operational phase of the proposed construction project comprises of various activities each of which will have impact on some or other environmental parameters. Various impacts during the construction or operational phase and the environmental parameters have been studied to estimate the impacts on environment. The identification and details on impact of the project activity on each of the above environmental attributes are discussed below.
2.2 IDENTIFICATION OF IMPACTS
The principal project activities that will be carried out during the construction and operational phases and the expected impacts on the environment due to the development are discussed in detail. Like any other projects, it also has impacts on existing Environmental settings and if not properly evaluated and controlled, it may lead to imbalances. These could be reversible, irreversible, temporary or permanent. The aim is to highlight specific activities that may have an impact on the existing environment so that appropriate mitigation and abatement measures can be instituted.
The identification of impacts is important as it leads to the other elements such as quantification and evaluation of impacts. Although a number of non-projects related impacts have been identified while describing the existing (baseline) environmental status, it is necessary at this stage to identify the types of the potential impacts which might be caused by the proposed development. Many techniques are available for identification of impacts. In case of this project, the "Matrix Method" was adopted, which involves an understanding of the cause- condition-effect relationship between an activity and environmental parameters. It
Conceptual Plan M/S. RAINBOW FOUNDATIONS LIMITED
is very useful as gross screening tool for impact identification method. This method has been basically advantageous in recognizing the series of impacts that could follow from the proposed activities.
The idea was to account for the project activity and identify the types of impacts that could initially occur. This process was repeated until all possible types of impacts were identified. With this method the potential impact of the proposed project has been identified.

Based on the above table, the possible impact during construction and operation phase has been projected, the impact evaluation and mitigation measures will be derived for air, water, soil, noise and ecological environment as per the positive and negative impacts, the most visible impact during construction phase is short time negative impact which is unavoidable, which is proposed to be mitigated by the pollution control measures,
• A water tanker is driven on-site spraying water over the affected areas preventing dust from airborne. • Hydro-seeding is one of the dust control methods preferred by construction projects. However, one important thing, depending on where this is located, seeds can be attractive to birds and wildlife, and you could end up losing about 50% of your seeds due to the birds.
• General refuse from site clearance would also be disposed of at landfills.
• Careful design, planning and good site management would be maintained to minimise over-ordering and waste of raw materials such as ready mixed concrete, mortars and cement grouts.
• Use of bentonite slurry in diaphragm wall and bore-pile construction should be reconditioned and reused, wherever practicable, to minimise the volume of used slurry to be disposed of and noise could be reduced in case of bore-piles.
• DPM- diesel particulate matter is PM10 which is injurious to health, which could be mitigated by mechanical filtration (i.e) the use of trees or other vegetation as a natural filtration system. Trees with the largest surface area have the greatest PM removal potential.
During operation phase sewage generation is notified as long term negative impact for
Conceptual Plan M/S. RAINBOW FOUNDATIONS LIMITED
which construction of SBR of 55 KLD for black water treatment and 45 KLD of grey water treatment plant and utilization of treated wastewater will be a proper mitigation measures as it is not disposed untreated into any channel or water body. Solid waste management will be other activity during construction and operation phase has to effectively manage by source segregation and installation of organic waste convertor. OWC 30 is used, which will Compost the organic waste into manure by the use of culture media. Resulting manure is used for in house plantation. Detailed impact evaluation is discussed below.
2.3 IMPACT EVALUATION
Impact evaluation assesses the expected changes in the environment due to the proposed project. It is the tool for identifying the magnitude of impact and forms basis for the development of Environmental Management Plan. Weight age for each impact is given below. Evaluation of impacts considering both positive and negative effects on air, noise, land, water and socioeconomic environment during the construction and operation phase of the project is given in Table 10 and 11 respectively.

The above table acts as tool for identifying the magnitude of impact which forms the basis for the development of Environmental Management Plan. Weight age for each impact is tabulated above, which indicates the possible activities during construction and operation phase that are likely to impact the environment. The potential impacts, whether positive or
Conceptual Plan M/S. RAINBOW FOUNDATIONS LIMITED
negative, long term or short term, direct or indirect, whether the impact can alter or cause damage to the particular environment or can it be controlled from the source, can it be reversible, has been clearly identified in the above table.
2.4 IMPACT ON AIR ENVIROMENT
2.4.1 Construction phase
Impacts of construction activities on air quality are cause for concern mainly in the dry months due to dust particles. The main sources of emission during the construction period are the movement of equipment at site and dust emitted during the leveling, grading, earthworks, and other construction related activities. The dust emitted during the above mentioned activities depend upon the type of soil being excavated. However, the impact will be for short duration and confined locally to the construction site. The composition of dust in this kind of operation is, however, mostly inorganic and non-toxic in nature.
The impact of such activities would be temporary and restricted to the construction phase. The impact will be confined within the project boundary and is expected to be negligible outside the plant boundaries.
The minimal impact on air environment during construction phase in the short time is predicted, due to the movement of transportation vehicles in site, digging and construction activity which can be mitigated by planting of thick canopy trees in surrounding of 100 meter radius of the site.
Proper upkeep and maintenance of vehicles, sprinkling of water on roads and construction site are some of the measures that would greatly reduce the impacts during the construction phase. Thus, it is inferred that no significant impacts are expected on the overall ambient air quality due to the proposed construction activities.
Transportation and Storage of Construction Materials
Transportation of heavy machinery and building materials implies heavy traffic on the roads leading to the site with possible negative impacts to the surrounding area (dust, spillage, emissions and noise). The transport of materials such as concrete and asphalt, gravel, sand and cement to construction sites generate significant amounts of road dust, especially for sites that are relatively far from material manufacturers. It will also lead to inadvertent dispersal of materials during heavy rain or high wind during dry periods. Measures will be adopted for proper handling of construction materials to reduce the negative impact.
Conceptual Plan M/S. RAINBOW FOUNDATIONS LIMITED
2.4.2 Operation Phase
Minimal impact due to traffic movement will envisage in air quality. Due to operation of diesel generators in the site the SO2 and NOX gaseous emission is contributed the environment which will have a indirect impact on ecological settings and factor contribution of acid rain. The impact can be restored by installation of proper stack and maintenance of DG sets.
Ambient air quality at the proposed project site and its surroundings will be monitored and values of the pollutants RPM, PM2.5, NOx and SO2 are within the limits of NAAQS, 2009 prescribed by the central pollution control board. The test reports are enclosed as Annexure.
There is no major pollutant envisaged from the proposed development. It is likely that the air quality may be affected slightly due to the demolition activity and emissions from the vehicular movement. The emission from DG sets will be very negligible since it will be used only during power cut in the necessary area. These emissions are insignificant and the environmental pollutant levels are being maintained within the prescribed limits, which can be inferred from the baseline report enclosed. Hence there shall not be any adverse impact on the air environment due to the Proposed Residential Group Development building.
2.4.3 Baseline data
Ambient air quality standard has been monitored within the project site as well as outside for the parameters as per 2009 NAAQ standard, sulphur dioxide concentration is 16 µg/m3 ,oxides of nitrogen is 29 µg/m3, PM10 is 73 µg/m3 and PM 2.5 is 32 µg/m3 and other parameters such as Co, lead, Ozone, Ammonia, Benzene, Benzo (a) pyrene , Arsenic, Nickel were below detectable limit which is also as per 2009 NAAQ standard. The Baseline monitoring reports are enclosed in Annexure. There is no significant impact on environment due to air environment in the project site based on the baseline report (Sampling date: 28.12.2017)
2.5 IMPACT ON AMBIENT NOISE
2.5.1 Construction Phase
During the construction phase, noise levels will increase due to use of machinery and heavy vehicles in the project area. In terms of noise emission; demolition, excavation and construction work can be divided into two phases, namely (1) Demolition and Earthworks and (2) building works. Hydraulic excavators and hammers for demolition, loading and unloading of construction materials, fabrication, handling of equipment and material, operation of power shovels etc. will be the major
Conceptual Plan M/S. RAINBOW FOUNDATIONS LIMITED
source of noise during the construction phase. Various construction activities will cause short- term noise impact in the immediate vicinity of the project site
The areas affected are those close to the site and hence the impacts are localized. At the peak of the construction, marginal increase in noise levels is expected to occur. The peak noise levels from continuous construction activity may be as high as 80 - 90 dB (A). The noise control measures during construction phase shall restrict the noise levels to lower levels. Hence the overall impact on the ambient noise levels will not be significant.
2.5.2 Operation Phase
There will not be any major impact from noise. This is because no equipment or other infrastructure facility in the project generates noise more than 50-60 dB (A). However, the only noise generation source is the DG set. The promoters have decided to adopt adequate steps to maintain the noise levels within the prescribed limits. For the same all the DG facility will be equipped with acoustic enclosure. Apart from this honking will be prohibited at the site and speed limits will be restricted within the site. This will significantly help in controlling noise levels at the site. Further the green belt provided within the site will act as noise barrier between inside and outside environment. This will act as buffer and protects the site from high noise levels outside the site.
Traffic Noise
Traffic will increase during both construction and operation phase of the project. Vehicles associated with construction would generate intermittent noise throughout the vicinity of the proposed action. In the operation phase, vehicular parking is being provided in the basement, and stilt of the building where noise levels are expected to increase substantially during the peak hours due to starting, idling and roaring of vehicles.
Baseline Data

5 Outside Project Site 51 41
Leq Day: 51 dB (A) Leq Night: 41 dB (A)
Conceptual Plan M/S. RAINBOW FOUNDATIONS LIMITED
The values were well within the limits prescribed by CPCB. Hence noise environment is not affected to a greater extent as per baseline report (sampling date: 28.12.2017)
2.6 IMPACT ON LAND ENVIRONMENT
No blasting will be done during construction phase of the project. The rehabilitation and resettlement issues are not involved in the project. Furthermore the existing environmental conditions of the project site reveal that the land is not contaminated or polluted, good condition report with following parameters within permissible limit pH 7.11 , water content 18.5% , Electrical conductivity 0.235 mS/cm and Chloride 42.4 mg/kg. Baseline report for Soil is enclosed in Annexure.
Top soil will be excavated up to 15 cm from the project site. It will be stored in covered area during construction phase and will be used for landscaping in operation phase within project site. The upper/top level of soil will be affected during construction phase but this will be limited to a portion of the project area. Also the impact due to exploitation of ground water is insignificant in the site due to the sourcing of water from other sources during the operation phases.
Since the proposed project involves construction of double basement, there involves excavation of 6.4 m below ground level. The water table in the site was observed at 4m during September month. We will carry out the excavation without disturbing the water table during summer season. The quantity of excavated earth material will be 38374 m3. The excavated earth material will be used for site filling and leveling. Water seeped during excavation will be collected separately and if the quality of water satisfies IS standard (IS 456 2000); it will be used for construction otherwise it will be disposed through storm water drain wit prior intimation.
2.7 IMPACT ON WATER RESOURCES
2.7.1 Construction Phase
The required water quantity for construction will be utilized from the available resource in the project area. In the proposed project Impact on water quality during construction phase may be due to non-point discharges of sewage generated from the construction work force, stationed at the site. Construction activities for the proposed development can have minor impact on hydrology and ground water quality of the area if the construction waste leaches into ground.
Potential sources of impacts on the hydrology and ground water quality during the construction phase would be soil runoff, improper disposal of construction debris, spillage of oil and grease from the vehicles and wastewater stream generated from on site activities such as vehicles washing, workshop etc. Precautions and
Conceptual Plan M/S. RAINBOW FOUNDATIONS LIMITED
preventive measure will be taken at the site during construction to avoid any ground and surface water contamination hence the overall impact on water environment during construction phase due to proposed project is likely to be insignificant.
2.7.2 Operation phase
The wastewater generation from the project is estimated to be about 93 KLD which will be treated in grey water treatment plant of 45 KLD capacity and STP of 55 KLD capacity (SBR Technology). The treated waste water from grey water treatment will be used for flushing and gardening. The treated waste water generated from STP will be used roadside avenue plantations.
2.7.3 Baseline data Ground water sample collected in the bore well in the project site, the TDS is 1325 mg/L and pH is 7.9 and, hardness(CaCO3) is 4778 mg/L, chloride 352 mg/L , sulphate 165 mg/L, Iron 0.215 mg/L. Baseline result for water is enclosed in Annexure XI. The values are greater than limits prescribed by IS 10500:2012 and also as the project site falls under critical zone, ground water cannot be extracted during operation. So no significant impact on ground water level as the water will be sourced from CMWSSB. Apart from that, ground water will be recharged by implementing rainwater harvesting scheme.
2.8 IMPACT DUE TO WASTE DISPOSAL
2.8.1 Stacking and Disposal of Construction Materials
Stacking of construction materials will be confined to the project site only and also temporary sheds will be provided to store the materials, hence no impacts on surrounding area will be envisaged. Solid wastes generated due to proposed project during construction phase include sand, gravel, stone, bricks, plastic, paper, wood, metal and glass. Recyclables will be sent to authorized recyclers. Hence there is no significant impact due to waste disposal during the construction phase.
2.8.2 Operation Phase
The solid waste generated from the project will be collected daily and moved to a common temporary storage facility by the staff dedicated for waste collection. The collected Solid waste will be disposed through Organic waste converter.
Conceptual Plan M/S. RAINBOW FOUNDATIONS LIMITED
2.9 IMPACTS ON ECOLOGICAL RESOURCES
2.9.1 Construction Phase
The impact of construction activities will be primarily confined to the project site. The project site is a vacant land and devoid of any vegetation. Thus the site development work will not lead to any significant loss of any important plant species. Deposition of fugitive dust on leaves of nearby vegetation may lead to temporary reduction of photosynthesis. Such impacts will, however, be confined mostly to the initial period of construction phase. Hence the proposed development will not lead to habitat destruction, fragmentation or vegetation damage.
2.9.2 Operation Phase
No wastewater will be discharged into the surface water stream. Hence, there will not be any impact on the aquatic ecology. Also the proposed project is to be located in an earmarked Residential zone, which does not have any natural park or sanctuary or forest area in the immediate vicinity. The flora and fauna pattern in the area will not be disturbed due to the project. Hence the overall impact on ecological resources due to proposed project is likely to be insignificant. Moreover the entire project area would be landscaped with variety of plants.
2.10 IMPACT ON TRAFFIC LEVELS
2.10.1 Construction Phase
The movement of construction equipments will be mostly within the site during the project. Vehicles bringing in raw materials like sand, cement and aggregate materials will be moving into the site from outside, which will be strictly controlled and monitored as per the traffic rules, to avoid any sort of disturbance to the traffic and safety of the surrounding areas. Hence the impact due to the vehicular movement during the construction phase would be minor or insignificant.
2.10.2 Operation Phase
Based on the vehicular density observed during the traffic survey conducted on the main roads around the proposed site, the existing infrastructure is capable of taking up additional traffic loads. Hence there will not be any impact on the traffic pattern and density.
2.11 IMPACTS ON SOCIO ECONOMIC ENVIRONMENT
The proposed residential group development building will be open to members of all communities and castes. The above measure will encourage mixing of different caste
Conceptual Plan M/S. RAINBOW FOUNDATIONS LIMITED
people for their respective festivals and occasions. This will improve the social welfare and brotherhood among the various communities and castes.
Also the state of the art facilities proposed in the development is planned to cater the needs of the occupants which would be able to provide healthy working atmosphere. Hence it is obvious to assume that the activities of the proposed development will produce some positive impacts in the socio-economic status of the area.
PUBLIC HEALTH AND SAFETY
As the project is only a construction of residential group development building and all the construction activities are confined to the project site, no health related impact would be envisaged within the project area. The people engaged in the construction activities will be directly exposed to dust generation, which is likely to cause health related impact. Appropriate mitigation measures like spraying of water will be adopted to minimize dust emission in the construction site. Laborers will be provided with suitable Personal Protective Equipment (PPE) as required under the health and safety norms. Regular health checkups will be organized.
POSITIVE IMPACT
The project will facilitate maximum participation of the local work force for construction process; this will benefit the local economy, improvement in economic activity and enhancement in earning opportunities for the local population. The operation of the project and other allied facilities will improve the employment opportunities. The project will provide direct and indirect employment. About 100 – 150 persons will be employed during the operation stage for the purpose of day-to- day maintenance works. The employment will have positive impact on the local economy thereby increasing the quality of life. The proposed rain water recharge facility will augment the ground water level in the project area. The proposed project will also improve the aesthetics of the area due to the development of modern buildings.
Conceptual Plan M/S. RAINBOW FOUNDATIONS LIMITED
3. ENVIRONMENTAL MANAGEMENT PLAN
3.1 GENERAL
Environmental Management Plan (EMP) is aimed at mitigating the possible adverse impacts of the project and for ensuring to maintain the environmental quality. The environmental management plan consists of the set of mitigation, management, monitoring and institutional measures to be taken to eliminate the adverse environmental impacts or reduce them to acceptable levels.
3.2 AIR POLLUTION CONTROL AND MANAGEMENT
3.2.1 Construction Phase
The impacts will be due to the air emissions like Particulate matter (PM10 & PM2.5, CO2,
NOx and SO2) due to material handling, vehicular movements and other site activities. The particulate matters will be reduced by frequent sprinkling water on the road surfaces and on other areas where dust is arising due to material handling. All the equipments and vehicles used in the construction and transportation of materials will be maintained properly and only low sulphur diesel will be used as fuel for DG sets and construction equipment and vehicles. Setting up temporary portable concrete plants and/or asphalt plants at construction sites can eliminate haulage of materials. Also proper coverage of material storage at site reduce dust emission due to wind.
The emissions from the DG sets will be let out only through the stacks with adequate heights as per CPCB norms. This will avoid the deposition of the particulate matters and other pollutants by facilitating the through dispersion of pollutants into the atmosphere. The stacking of all the construction materials will be confined only within the proposed site. Vehicles carrying the raw material and debris will be covered to minimize dust emissions while travelling. Adequate parking space will be provided for construction vehicle and machinery to prevent idling and thus will help in minimizing the emissions. Wheel wash facility will be provided at the exit point of the site.
3.2.2 Operation Phase
Air emissions are observed during the operation phase of the project. The air emissions will be reduced by ensuring smoother flow of traffic within the premises by better traffic management plans. It is proposed to have trees all through the boundaries of the site and along the either side of the internal roads. This will reduce the particulate matters from being transported to the nearby areas. The air emissions from the Diesel Generators will be controlled by using low sulphur content
Conceptual Plan M/S. RAINBOW FOUNDATIONS LIMITED
high speed diesels, periodic maintenance of DG sets as per the defined schedule of manufacturer and by providing adequate stack heights as prescribed by CPCB. The stack height for the DG sets are calculated based on the CPCB guidelines as shown below;

3.2.3 Air pollution control (APC) Measures
The main source of air emissions from the proposed development is the Generator Sets the above proposed generator sets will be used only during TNEB power failure. To control the air emissions from these D.G sets, adequate stack height is provided to release the exhaust flue gases into the atmosphere at a height at which efficient dispersion takes place. Since the DG sets are operated only during power failure, the emission is not continuous and hence the impact due to these emissions is insignificant.
The stack height for the DG sets are calculated based on the CPCB guidelines as shown below;
Stack Height Design Calculation for 320 KVA, H = h + (0.2) (320) 0.5
= 60 + 0.2 (320) 0.5
= 60 + 3.5
= 63.5 ~ 64 m.
Stack Height Design Calculation for 125 KVA, H = h + (0.2) (125) 0.5
= 60 + 0.2 (125) 0.5
= 60 + 2.23
= 62.23 ~ 63 m.

3.3 NOISE CONTROL AND MANAGEMENT
3.3.1 Construction Phase
The noise generated from the construction equipments will be reduced through proper maintenance of all the equipments which are involved in construction activities, confining the construction activities only during the day time and providing barricades all around the project area. The adverse impacts of noise especially on workers will be reduced by providing ear muffs to the workers in high noise zones. Noise control systems such as equipment foundation pads, dampeners, silencers and acoustic enclosures will be used for individual units as per the requirement to minimize the noise & vibration. Equipments will be selected to ensure that the noise level will be less than 55 dB(A). The earth moving equipments will be periodically checked and maintained for noise levels.
3.3.2 Operation Phase
The increase in the ambient noise levels due to the vehicle transportation will be controlled by the development of the green cover all along the internal roads and by implementing better traffic management plans inside the site premises. The better traffic management plans will significantly reduce the noise generated due to the congestion caused by the movement of vehicles.
In a typical DG set, the primary sources of noise are:
• The cooling fan. • The exhaust. • The engine body noise. • The intake. • Other moving components.
The effect of different loads on the noise level is much weaker than the effect of speed. The fact is that the number of components on diesel engine exhibit similar overall noise levels. The generator noise is controlled by providing acoustic enclosures. Proper air ventilation system is designed to allow the maximum aspiration and cooling airflow required so that the engines do not overheat. Axial flow fan of required size & numbers provided for proper air ventilation. Acoustic louvers, splitter & insulated ducts are provided to suppress the noise where required. Also during operation care will be taken to ensure that there will not be any incremental load in the environment.

3.4 SOLID WASTE MANAGEMENT
3.4.1 Construction Phase
Separate raw material handling yard will be demarcated. This will prevent the contamination of the soil due to the spillage of the construction materials. Cement will be separately stored under cover in bales. The raw material handling yard will be located within the project site and separated by enclosures/barricades. This will keep the working area clean and reduce the soil contamination. The solid waste expected to be generated during the construction phase will comprise of excavated materials, used bags, bricks, concrete, MS rods, tiles, wood etc. The following steps are proposed to be followed for the management solid waste:
• Construction yards are proposed for storage of construction materials.
• The excavated material such as topsoil and stones will be stacked for reuse during later stages of construction.
• Excavated top soil will be stored in temporary constructed soil bank and will be reused for landscaping.
• Remaining soil shall be utilized for refilling / road work / rising of site level at locations etc.

It is estimated that the municipal solid wastes will be generated in the following
Biodegradable wastes : 0.17072 Tons/day Recyclable wastes : 0.05432 Tons/day Inert wastes : 0.16296 Tons/day Sludge from STP : 5 Kg/day
In the Residential Housing development, Wastes generated from the households will be segregated in the source itself (by the occupants) in three separate bins. The wastes from such bins are collected separately on daily basis and taken to a separate centralized collection facility by the agency dealing in collection and disposal of garbage. Appropriate site will be identified for keeping the biodegradable and Non- biodegradable waste. All the collection bins shall be properly maintained and cleared on regular basis. The Bio degradable wastes & inert fractions will be disposed off through the local municipality, and non-bio degradable recyclable waste will be handed over to authorized recyclers.
Horticulture wastes leaves, grass and vegetative residues shall be collected at the secured location such that it will not hinder daily activity schedule or washed away by the surface run-off causing choking of drains, etc. and will be separately treated
Conceptual Plan M/S. RAINBOW FOUNDATIONS LIMITED
and disposed off along with biodegradable waste. STP sludge will be stabilized, and dewatered for separation of solids, which will be used as manure in horticulture.
Figure 5: Solid waste management
3.4.3 Organic waste convertor
Composting is the process in which the organic waste is degraded and converted into manure by the use of culture media. Composting is done using microorganisms, fungi or earthworms. For limited quantity of waste, the seven pit method is used and operated. However, this takes a long time and requires constant monitoring. Hence for huge quantity of waste generated, organic waste converters (OWCs) are used.
Total bio waste generation : 0.17072 Tons / day OWC model proposed : OWC 30 Waste treatment per batch : 10 kg Time taken for each batch : 15 min
Benefits of Organic waste converter
• Large quantity of solid waste is converted to fertilizer in a very short period
• Fertilizers can be sold as compost to farmers, or used for gardening
• Machine requires less space and the efficiency is high
• Manpower and maintenance is very less
• This is one of the latest techniques of managing solid waste.

Effective emergency action can avoid the escalation of an event into a disaster. Emergency management involves plans and institutional arrangements to engage and guide the efforts of government, non-government, voluntary and private agencies in comprehensive and coordinated ways to respond to the entire spectrum of emergency needs. The overall objective of an Emergency Response Plan (ERP) is to make use of the combined resources at the site and outside services to achieve the following: 1. To localize the emergency and if possible eliminate it; 2. To minimize the effects of the accident on people and property; 3. Make the rescue and medical treatment of casualties more effective; 4. Safeguard other people; 5. Evacuate people to safe areas; 6. Informing and collaborating with statutory authorities; 7. Initially contain and ultimately bring the incident under control; 8. Preserve relevant records and equipment for the subsequent enquiry into Conceptual Plan M/S. RAINBOW FOUNDATIONS LIMITED the cause and circumstances of the emergency; 9. Investigating and taking steps to prevent reoccurrence The ERP is therefore related to identification of sources from which hazards can arise and the maximum credible loss scenario that can take place in the concerned area. The plan takes into account the maximum credible loss scenario - actions that can successfully mitigate the effects of losses/ emergency need to be well planned so that they would require less effort and resources to control and terminate emergencies, should the same occur. Main hazards identified for the project include hazards pertaining to fires in buildings and fire in diesel storage areas, earthquake and LPG leakage and an ERP pertaining to these is described in the following section. 3.13.1 Response in case of Flood 3.13.1.1 Flood preparedness 1.

Stay inside: The most dangerous thing to do during the shaking of an earthquake is to try to leave the building because objects can fall on you. 3.13.2.3 If outdoors Move into the open, away from buildings, streetlights, and utility wires. Once in the open, stay there until the shaking stops. 3.13.2.4 If in a moving vehicle Stop quickly and stay in the vehicle. Move to a clear area away from buildings, trees, overpasses, or utility wires. Once the shaking has stopped, proceed with caution. Avoid bridges or ramps that might have been damaged by the quake. 1. After the earthquake be prepared for aftershocks. 2. Although smaller than the main shock, aftershocks cause additional damage and may bring weakened structures down. 3. Aftershocks can occur in the first hours, days, weeks, or even months after the quake. Conceptual Plan M/S. RAINBOW FOUNDATIONS LIMITED 4. Help injured or trapped persons. 5. Give first aid where appropriate. Do not move seriously injured persons unless they are in immediate danger of further injury. Call for help. 6. Remember to help those who may require special assistance--infants, the elderly, and people with disabilities. 7. Stay out of damaged buildings. 8. Use the telephone only for emergency calls. 3.13.2.5 Response procedure for emergency team 1. Formulate an Emergency Response Team for earthquake response. 2. Using the public address system, inform people of response procedures discussed above. 3. Inform the necessary authorities for aid. 4. Ensure no person is stuck beneath any debris, in case of a structural failure. 5. Ensure that all occupants standing outside near the buildings are taken to open areas. 6. Ensure that the first aid ambulance and fire tender vehicles are summoned if necessary. 7. Inform the nearby hospitals if there are any injuries. 8. Check the utilities and storage tanks for any damage. 3.13.3 Response in case of fire 3.13.3.1 Fire preparedness 1. Note the location of alarms and extinguishers. Know how to use them 2. Leave fire doors closed at all times 3. Clear obstructed corridors, aisles and room exits 4. Limit use of extension cords and multiple outlets Conceptual Plan M/S. RAINBOW FOUNDATIONS LIMITED 5. Do not use mechanical rooms or utility rooms for storage 3.13.3.2 Response procedure for occupants 1. Required response during in the event of a fire should be described in signs located in the lobby. 2. On sighting a fire, it should be immediately informed to the environment manager giving the exact location and type of fire in detail. 3. Initiate the Emergency Response Team for fires. 4. If the fire is small, engage in extinguishing the fire using the nearest fire extinguisher. 5. Guide the Emergency Response Team staff to the emergency assembly point. 6. The Emergency Response Team should immediately inform the nearest dispensary and security force. If required a fire tender should be summoned The response team should immediately move to the point of fire and take all necessary steps to stop the fire. If the fire is not controllable and spreads then the manager in charge should inform the district authorities and call for external help. 7. The Emergency Response Team will provide immediate relief to the injured at the scene of incident. Any injured persons should be evacuated on priority to the dispensary or one of the nearest hospitals based on their condition. 3.13.3.3 Instructions for occupants 1. Get out of buildings as quickly and as safely as possible. 2. Use the stairs to escape. When evacuating, stay low to the ground. 3. If possible, cover mouth with a cloth to avoid inhaling smoke and gases. 4. Close doors in each room after escaping to delay the spread of the fire. 5. If in a room with a closed door. 6. If smoke is pouring in around the bottom of the door or if it feels Conceptual Plan M/S. RAINBOW FOUNDATIONS LIMITED hot, keep the door closed. 7. Open a window to escape or for fresh air while awaiting rescue. 8. If there is no smoke at the bottom or top and the door is not hot, then open the door slowly. 9. If there is too much smoke or fire in the hall, slam the door shut. 10. Stay out of damaged buildings. 11. Check that all wiring and utilities are safe. A state of the art fire fighting system is proposed for the project to prevent and control fire outbreaks. The fire fighting system will consist of portable fire extinguishers, hose reel, wet riser, yard hydrant, automatic sprinkler system, and manual fire alarm system. The buildings will also be provided with automatic fire detection and alarm system. 3.14 ENVIRONMENT MONITORING PLAN FOR CONSTRUCTION AND OPERATION PHASE Environmental monitoring plan is a vital process of any management plan of the development project. This helps in signaling the potential problems that resulting from the proposed project and will allow for prompt implementation of effective corrective measures. The environmental monitoring will be required for the construction and operational phases. The main objectives of environmental monitoring area: • To assess the changes in environmental conditions, • To monitor the effective implementation of mitigation measures, • Warn significant deteriorations in environmental quality for further prevention action. The emissions from each of the diesel generator shall be monitored for exit concentration of Sulphur dioxide, Oxides of Nitrogen and Particulate Matter on regular intervals. The frequency of monitoring shall be decided in consultation with the TNPCB. Sampling ports in the stacks/vents shall be provided in accordance with CPCB guidelines. Conceptual Plan M/S.
