VI. RAINWATER HARVESTING AND RECHARGE

 Rooftop open area water is proposed to be collected in separate rain water harvesting sumps which will be used for domestic purposes of the proposed project after appropriate primary treatment required.  Storm water runoff from road / paved / landscaped areas will be directed to rain water percolation pits constructed along the project premises.

Basic Assumptions

 Average rain fall Considered = 1194 mm (IMD, Tenkasi); No. of rainy days = 60  Intensity of rainfall = 1194/60 = 19.90 mm/day or 0.019 m/day

TABLE–12 RUN-OFF CALCULATIONS

Harvestable water Area Impermeability Sr.No. Category (Intensity x Area (Sq.m.) Factor x Imp. Factor) cum/day

1 Ground coverage 81397 0.6 927.9 (Terrace)

2 Landscaped area 207409.07 0.3 1182.23 (Green area & OSR)

3 Road/Paved area 31097.42 0.9 531.76

Total 319903.49 2641.89

Run-off from Terraces

Considering the constant co-efficient factor of 0.80 (for all situations) for evaporation, spillage and first flush wastage (Source: CPWD Manual, 2002)

From Building area = 927.9 cu.m x 0.80 (for all time) = 742.32 cu.m

 The run-off from the terraces shall be separately piped to an underground collection sump, after duly filtering the same. This water is proposed to be used as domestic water after necessary treatment.  UG Storage sumps is proposed, with upstream filters.

Run-off from Roads, Paved area & Landscape area

Storm runoff from open area, greenbelt area and paved area = 1713.99 cu.m x 0.80 (for all time) = 1371.19 cu.m

All the water shall be routed to rainwater harvesting pits

 The run-off from terraces, roads, paved area & greenbelt & vacant area will be diverted through storm water network to individual percolation pits proposed along

M/s. Highland valley corporation Pvt Ltd, Chennai, Tamil Nadu Conceptual Plan the project periphery and the rain water will be re-charged into underground aquifers;  A percolation rate of 0.51 is considered with percolation depth as 10m;  Run-off = 1371.19 X (1.0 – 0.51) = 671.8 m3;  Size of percolation pit = 1.98 m Ø and 3.96 m depth;  Storage volume in each pit: 12.20 m3;  Quantity of storm water run-off: 671.80 m3;  No. of storage pits required: 671.80 m3/ 12.20 m3 = 55; and  55 Nos. of percolation pits will be constructed along the project site periphery for rain water recharge.

VII. SOLID WASTE MANAGEMENT

The total waste generated from the entire project amounts to around 0.907 MT/day. Out of which biodegradable will be about 0.544 MT/day (i.e.60%) and non-biodegradable will be about 0.363 MT/day (i.e.40%).

Organic solid-waste will be treated in an organic waste converter after used manure for garden and inorganic waste is proposed for recycling through authorized recyclers. STP sludge generated from the STP will be used as manure for garden.

Solid waste generated from the project is calculated as below:

X. CONCLUSION

The establishment of the proposed project by M/s. Highland valley corporation Pvt Ltd, Kadayam Perumpathu Village, Mathapuram, Ambasamudram Taluk, Tirunelveli District, Tamil Nadu, is best suited with the kind of climate that the area has. The proposed project would cater to the people working in this area.

Ground water point of view

The project consumes about 369 KLD of fresh water in a day which will be sourced from Wells in the plant. The wastewater will be treated and re-used for toilet flushing and garden maintenance.

Soil quality point of view

The soil analysis was already carried out, and was found to be good. There are no chances of soil contamination and no discharge of wastewater from unit operations which may contaminate the ground water table.

Air quality point of view

Air emissions will be only from DG Sets, for which stacks are provided with a height of 3m above building height for all DG Sets. Added to this, the fuel used is ultrapure low sulphur content diesel and thus the emissions will be lowest.

Submitted by M/s. Highland valley corporation Pvt Ltd, Chennai, Tamil Nadu Conceptual Plan

Noise quality point of view

The generation of noise from proposed project is negligible, as the only noise generating equipments are the DG Sets which comes with an inbuilt acoustic enclosure which has noise levels <75 dB.

Floral & Faunal diversity point of view

No kind of Floral & Faunal destruction is envisaged for the current project. As a matter of fact, the project is going to add further to the existing situation as landscape development is proposed for about 8.71 ha.

Hazardous waste point of view

The proposed project will not generate any hazardous waste except for the spent oil from the DG Sets. However, the authorization of the Tamil Nadu Pollution Control Board will be obtained as per the norms of the Hazardous Waste Management Rules. The waste oil from the DG Sets will not be discarded in any open area. Hence there is no threat to the soil and the neighboring area due to waste oil.

Final Conclusion

The proposed project would have very less negative impact on the surrounding area or on the environment. The proposed project would indeed help the socio economic condition of the area and it is very highly recommended for the establishment of the project. The project would not have any negative impact on the soil, water, air or noise environment.

 Treated Tank

SEWAGE TREATMENT PLANT DESCRIPTION

RAW SEWAGE COLLECTION TANK

The sewage effluent from the various sources is collected in raw sewage collection tank after passing through the coarse screen channel. Then the sewages are pumped into the fine screen channel.

FINE SCREEN CHANNEL

Fine screens are mechanically cleaned devices using perforated plates, woven wire cloth or very closely spaced bars with clear openings of less than 20 mm. Fine screens are built between the grit chambers and primary sedimentation tank in order to remove some amount of suspended solids from sewage. The fine screens often get clogged need frequent cleaning. The brass metal is used as it has higher resistant towards rust and corrosion. Here the disc type fine screen is designed and the wire mesh of the screen is made up of brass metal. The fine screen is attached with electric motors. The clogged screen is often cleared by cone brush.

GRIT CHAMBER MANUAL

Grit removal basins are the sedimentation basins placed in front of the fine screen to remove the inorganic particles having specific gravity of 2.65 such as sand, gravel, grit, egg shells and other non- putrescible materials that may clog channels or damage pumps due to abrasion and to prevent their accumulation in sludge digesters. The grit chamber is designed to scour the lighter organic particles while the heavier grit particles remain settled. After primary treatment the sewage is send to parallel SBR Basins for biological degradation of organics.

SBR BASINS

The primary treated sewage is pumped into the two SBR Basins . These two SBR Basins are work in sequence and influent flow is controlled using motorized sluice gates. The complete biological treatment is divided into Cycles with each Cycle is of 3.00 hrs duration, during which all treatment steps take place. A basic Cycle comprises of the following phases which take place independently in sequence to constitute a Cycle and then gets repeated.

 Fill  React  Settle  Decant  Ideal

FILL

During the fill phase, the basin receives influent wastewater. The influent brings food to the microbes in the activated sludge, creating an environment for biochemical reactions to take place. REACT

This phase allows for further reduction or "polishing" of wastewater parameters. During this react phase, no wastewater enters the basin and the mechanical mixing and aeration units are on. Because there are no additional volume and organic loadings, the rate of organic removal increases dramatically. Most of the carbonaceous BOD removal occurs in the react phase. Further nitrification occurs by allowing the mixing and aeration to continue—the majority of denitrification takes place in the mixed-fill phase. The phosphorus released during mixed fill, plus some additional phosphorus, is taken up during the react phase.

SETTLE

During settling phase, the filling and aeration is stopped and the biomass is allowed to settle under perfect settling conditions during settling phase. Once settled the supernatant is removed from the top using a decanter and excess sludge is wasted during decanting phase.

DECANT During decanting there is no inflow to the basin and a decanter is used to remove the clear supernatant effluent. Once the settle phase is complete, a signal is sent to the decanter to initiate the opening of an effluent-discharge valve. There are floating and fixed-arm decanters. Floating decanters maintain the inlet orifice slightly below the water surface to minimize the removal of solids in the effluent removed during the decant phase. Floating decanters offer the operator flexibility to vary fill and draw volumes. Fixed-arm decanters are less expensive and can be designed to allow the operator to lower or raise the level of the decanter. It is optimal that the decanted volume is the same as the volume that enters the basin during the fill phase. It is also important that no surface foam or scum is decanted. The vertical distance from the decanter to the bottom of the tank should be maximized to avoid disturbing the settled biomass.

IDLE

Ideal phase is occurring between the decant and the fill phases. The time varies, based on the influent flow rate and the operating strategy. During this phase, a small amount of activated sludge at the bottom of the SBR basin is pumped out -a process called wasting. The treated sewage from the SBR Basins is send to chlorine tank for further treatment.

CHLORINATION TANK

The effluent is subjected to disinfection by chlorination in chlorine tank and effluent after disinfection can be used for Toilet Flushing / Gardening / landscaping within the premises as it is ensured to meet the discharge standards specified by the Pollution Control Board for on land irrigation.

SLUDGE DISPOSAL

A sludge pump is provided to periodically remove the solids accumulated at the bottom of settling tank. The Sludge is pumped to a Sludge Digester / and the excess sludge is sent to the sludge drying beds for sludge drying. The dried sludge can be used as manure by mixing with fertilizer for Landscaping / Gardening.

TREATED TANK

The treated sewage effluent is collected from the chlorination tank and further utilized for gardening and flushing. Assumed effluent characteristics expected after the treatment in sewage treatment plant for gardening as given below.

RISK ASSESSMENT

Risk Assessment / Disaster Management Plan for the proposed IT office buildings by M/s. Highland valley corporation Pvt Ltd at Kadayam Perumpathu Village, Mathapuram, Ambasamudram Taluk, Tirunelveli District, Tamil Nadu

Risk Assessment

Risk analysis involves the identification and assessment of risks the persons involved in the proposed project and the neighboring populations are exposed to, as a result of hazard occurrence. This requires a thorough knowledge of failure probability, credible accident scenario, vulnerability of population etc. Much of this information is difficult to get or generate. Consequently, the risk analysis is often confined to maximum credible accident studies.

In the sections below, the identification of various hazards, probable risks in the proposed project, maximum credible accident analysis and consequence analysis, which give a broad identification of risks involved, are addressed. Based on the risk estimation for fuel storage, a Disaster Management Plan (DMP) has been presented.

Approach to the Study

Risk involves the occurrence or potential occurrence of certain accidents consisting of an event or sequence of events. The risk assessment study covers the following:

 Identification of potential hazard areas;  Identification of representative failure cases;  Visualization of the resulting scenarios in terms of fire (thermal radiation) and explosion;  Assessment of the overall damage potential of the identified hazardous events and the impact zones from the accidental scenarios;  Assessment of the overall suitability of the site from hazard minimization and disaster mitigation points of view;  Furnishing specific recommendations on the minimization of the worst accident possibilities; and  Preparation of Disaster Management Plan (DMP), On-site and Off-site Emergency Plan, which includes Occupational, Health and Safety Plan.

Hazard Identification

Identification of Hazards in the proposed project is of primary significance in the analysis, quantification and cost effective control of accidents involving HSD. A classical definition of hazard states that hazard is in fact the characteristic that presents potential for an accident. Hence, the components of the proposed project need to be thoroughly examined to assess their potential for initiating or propagating an unplanned event/sequence of events, which can be termed as an accident. The following two methods for hazard identification have been employed in the study:

 Identification of major hazardous units based on Manufacture, Storage and Import of Hazardous Chemicals Rules, 1989 of Government of India (GOI Rules, 1989); and

 Identification of hazardous units and storage units based on relative ranking technique, viz. Fire-Explosion and Toxicity Index (FE&TI).

Vimta Labs Limited, Hyderabad/Coimbatore 1

Identification of Major Hazardous Units

Hazardous substances may be classified into three main classes such as flammable substances, unstable substances and toxic substances. The ratings for a large number of chemicals/substances based on flammability, reactivity and toxicity have been given in NFPA Codes 49 and 345 M. In the proposed project, HSD will be stored in-build the DG set for generation of power in case of grid failure. The details of HSD storage and its classification as per GOI rules are given in Table-1. Hazardous characteristics of HSD are listed in Table-2.

Common Causes of Accidents

Based on the analysis of past accident information, common causes of accidents are identified as:

 Poor housekeeping;

 Improper use of tools, equipment and facilities;

 Unsafe or defective equipment;

 Lack of proper procedures;

 Failure to follow prescribed procedures;

 Improper understanding of jobs;

 Lack of awareness of hazards involved;

 Lack of guides and safety devices; and

 Lack of protective equipment and clothing.

Vimta Labs Limited, Hyderabad/Coimbatore 2

Failures of Human Systems

Major causes of human failures reported are due to:

 Stress induced by poor equipment design, unfavorable environmental conditions, fatigue, etc;  Lack of training in safety and loss prevention;  Indecision in critical situations; and  Employment of inexperienced staff in hazardous situations.

Often, human errors are not analyzed while accident reporting and accident reports only provide information about equipment and/or component failures. Hence, a great deal of uncertainty surrounds analysis of failure of human systems and consequent damages.

Hazard Assessment and Evaluation

Methodology

An assessment of the conceptual design is conducted for the purpose of identifying and examining hazards related to utility and support systems, environmental factors, facilities, and safeguards.

Preliminary Hazard Analysis (PHA)

A preliminary hazard analysis is carried out initially to identify the major hazards associated with storages in the proposed project. This is followed by consequence analysis to quantify these hazards. No major hazards with potential for any emergency situation exist in the project site. The other hazards related to the storage areas are given below in Table-3 and the preliminary hazard analysis for the proposed project is given in Table-4.

Maximum Credible Accident Analysis (MCAA)

Hazardous substances may be released as a result of failures or catastrophes, causing possible damage to the surrounding area.

In addition to provided. the above, fire hydrant network is also provided

A disastrous situation may arise due to outcome of fire, explosion or toxic hazards in addition to other natural causes, which eventually leads to loss of life, property and ecological imbalance.

Major hazards posed by flammable storage can be identified taking recourse to MCA analysis. Depending upon the effective hazardous attributes and their impact on the event, the maximum effect on the surrounding environment and the respective damage caused can be assessed.

The results of consequence analysis are useful for getting information about all known and unknown effects that are of importance, when some failure scenario occurs in the proposed project and also to get information as to how to deal with the possible catastrophic events. It also gives the people living in the vicinity of the area, an understanding of their personal situation.

Damage Criteria

The Inbuilt storage of HSD in the DG Sets and unloading facility may lead to fire and explosion hazards. The damage criteria due to accidental release of any hydrocarbon arise from fire and explosion. The vapors of these fuels are not toxic and hence no effects of toxicity are expected.

Tank fire will occur if the radiation intensity is high on the peripheral surface of the tank leading to increase in internal tank pressure. Pool fire will occur when fuel collected due to leakage gets ignited.

Vimta Labs Limited, Hyderabad/Coimbatore 4

Fire Damage

A flammable liquid in a pool will burn with a large turbulent diffusion flame. This releases heat based on the heat of combustion and the burning rate of the liquid. A part of the heat is radiated while the rest is convected away by rising hot air and combustion products. The radiations can heat the contents of a nearby storage or process unit to above its ignition temperature and thus result in a spread of fire. The radiations can also cause severe burns or fatalities of workers or fire fighters located within a certain distance. Hence, it will be important to know beforehand the damage potential of a flammable liquid pool likely to be created due to leakage or catastrophic failure of a storage or process vessel. This will help to decide the location of other storage vessels and decide the type of protective clothing the workers/fire fighters need, the duration of time for which they can be in the zone, the fire extinguishing measures needed and the protection methods needed for the nearby storage / process vessels. The damage effects on people and equipment due to thermal radiation intensity are presented in Table-5 and Table-6 respectively.

Recommended Approach to Combat with the Possible Accidents

Considering all possible accident scenarios as analyzed in the risk analysis, it is established that there will not be any major potential hazards in the project, causing major damages inside and outside the boundary. In spite of this, the project authorities should be well prepared to handle any such eventuality as described below:

In case of Explosion

The following measures and actions are to be taken:

 Evacuate the area in vicinity;  Take all necessary actions to avoid escalation of the accident;  If problem appears to be out of control, call fire brigade and police and report to district collector and other officials; and  Provide first aid to the victims as suggested in the Material Safety Data Sheets.

Spillage due to storage tank rupture or tanker failure

This accident scenario has considerable damage potential. In such scenario the following steps should be taken:

 Contain fuel supply to the tankers;  Determine the extent of damage; and  Undertake all the emergency actions mentioned above.

Spillage from Storage tank, storage tank/tanker overfilling, pipe-hose rupture

In addition to the measures stated above, the following actions are to be taken:

 Stop further process of filling immediately;  Note the amount of fuel spilled in the area;  If the tanker is on the road, communicate about the accident to the traffic police; and  Take help of the traffic police for preliminary emergency actions.

Major Spillage due to storage tank rupture or tanker failure

This accident scenario has considerable damage potential. In such case the following steps have to be taken up:

Vimta Labs Limited, Hyderabad/Coimbatore 6

 Determine the extent of damage;  Contain fuel supply to HSD tanks; and  Undertake all the emergency actions mentioned above.

Accident Involving HSD

In case of leakage of oil from flanges, valves, tail ends or during transfer from truck tanker (TTS):

 Detect the source of leakage;  If possible, try to collect the leaking oil in a suitable container;  Bring portable fire extinguishers near to the area of leakage; and  Stop flow of spilled oil and prevent it from coming into contact with any ignition source.

If HSD is ignited at the source of leak

In addition to the above, following actions are to be taken:

 Use fire extinguishers to diminish the fire;  See that the flame does not impinge on tanks or any other adjacent installation;  If impingement of flame is unavoidable, put water curtain in between and cool the adjacent installations;  Give priority to closure of valve and stop the flow;  Best trained personnel to prevent further spread of fire;  Take all necessary actions to avoid escalation of the accident; and  In case of fire, ensure suffocation and toxicity due to flame does not take place.

In case of fire near HSD storage tanks

 If the fire is near the storage tanks area, use water hydrant and DCP type fire extinguishers;  Never allow fire to spread to the area below the tank, start cooling the tank by the emergency water spray; and  Call fire brigade & police for assistance.

Disaster Management Plan

A disaster is a catastrophic situation in which suddenly, people are plunged into helplessness and suffering and as a result, need protection, clothing, shelter, medical and social care and other necessities of life.

Disasters can be divided into two main groups. In the first, disasters include those resulting from natural phenomena like earthquakes, volcanic eruptions, storm surges, cyclones, tropical storms, floods, avalanches, landslides, forest fires etc. The second group includes disastrous events occasioned by man, or man’s impact upon the environment. Examples are armed conflict, radiation accidents, campus fires, river pollution, air, sea, rail and road transport accidents that can reach catastrophic dimensions in terms of human loss.

Vimta Labs Limited, Hyderabad/Coimbatore 7

There can be no set criteria for assessing the gravity of a disaster in the abstract since this depends to a large extent on the physical, economic and social environment in which it occurs. What would be considered a major disaster in a developing country, ill-equipped to cope with the problems involved, may not mean more than a temporary emergency elsewhere. However, all disaster brings in their wake, similar consequences that call for immediate action, whether at the local, national or international level, for the rescue and relief of the victims. This includes the search for the dead and injured and removal of debris and social care, the provision of temporary shelter to the homeless food, clothing and medical supplies, and the rapid re- establishment of essential services.

Objectives of Disaster Management Plan (DMP)

The Disaster Management Plan is aimed to ensure safety of life, protection of environment, protection of installation, restoration of production and salvage operations in this same order of priorities. For effective implementation of the Disaster Management Plan, it will be widely circulated and personnel training given through rehearsals/drills.

The Disaster Management Plan would reflect the probable, consequential severalties of the undesired event due to deteriorating conditions or through ‘Knock on’ effects. Further the management should be able to demonstrate that their assessment of the consequences uses good supporting evidence and is based on currently available and reliable information, incident data from internal and external sources and if necessary the reports of outside agencies.

To tackle the consequences of a major emergency inside the factory or immediate vicinity of the factory, a Disaster Management Plan has to be formulated and this planned emergency document is called “Disaster Management Plan”.

The objective of the Disaster Management Plan is to make use of the combined resources of the IT office and the outside services to achieve the following:

 Effect the rescue and medical treatment of casualties;  Safeguard other people;  Minimize damage to property and the environment;  Initially contain and ultimately bring the incident under control;  Identify any dead;  Provide for needs of relatives;  Provide authoritative information to the news media;  Secure the safe rehabilitation of affected area; and  Preserve relevant records and equipment for the subsequent inquiry into the cause and circumstances of the Emergency.

In effect, it is to optimize operational efficiency to rescue rehabilitation and render medical help and to restore normalcy.

8.0 DESIGN CRITERIA - A DISCUSSION

8.1 Primary Parameters

8.1.1 The parameters required for the design of foundation system for the proposed structure

are:

G(C)9337

17 a) Type of foundation to be adopted

b) Depth at which the foundations have to be laid

c) Allowable bearing pressure on the soil at the foundation level

8.1.2 On the basis of the analysis of the results of investigations, the required design parameters

have been arrived at and these are given in paras 8.2 to 8.4.

8.2 Type of Foundations

8.2.1 The type of foundation depends on the following:

a) Sub soil conditions

b) Type of structure

c) Configuration at loading points

d) Loading intensity on each sub-structure/structural element.

8.2.2 As per the client’s information, the proposed structure is a IT Block comprising of ground

floor and 2/3 upper floors.

8.2.3 As seen from the investigations the soil is in a medium dense / dense state.

8.2.4 For the above conditions, Isolated/strip foundations can be adopted for the proposed

structures.

8.3 Depth of Foundation

8.3.1 The depth at which foundations should be laid will be governed by the following criteria.

a) There should be sufficient thickness of soil above the footings/foundations so that

they are neither exposed or undermined by natural/manmade forces in the future.

b) There should be sufficient thickness of soil above the footing/foundations so that

the bearing capacity of the soil can be fully mobilised.

c) Soil below the level of footings/foundations should have the requisite strength to

support the anticipated bearing pressures on the foundations without allowing the

G(C)9337

18 settlement of footings/foundations to exceed the acceptable limits.

d) Requirements of the type of structure (IT Block comprising of ground floor and

2/3 upper floors).

8.3.2 In view of the above factors, foundations of the proposed structure can be made to rest

at a depth of 2m below the existing ground level or 30cm in weathered rock whichever

is deeper. The strata available at the founding level will be highly weathered rock.

8.4 Allowable Bearing Pressure

8.4.1 An allowable settlement of 40mm has been considered to evaluate the allowable bearing

pressure for Isolated/strip foundations.

8.4.2 Allowable bearing pressure has been evaluated by:

a) Shear failure criteria taking the average soil data

b) Settlement criteria taking SPT values (N-values)

c) Settlement criteria based on deformation modulus

8.4.3 A water table correction factor of 0.5 has been considered.

8.4.4 The allowable bearing pressure at 2m depth below the existing ground level is 40t/m².

8.4.5 Sample calculation for allowable bearing pressure is provided in Appendix A.

9.0 RECOMMENDATIONS

9.1 The recommendations for the proposed structure (IT Block comprising of ground floor

and 2/3 upper floors) are given below:

a) Type of Foundations : Isolated/strip

b) Depth of foundations : 2m below the existing ground level or

30cm in weathered rock; whichever is

deeper.

c) Allowable bearing pressure : 40t/m²

d) Settlement considered for calculations: 12mm (as per IS 13063-1991).

G(C)9337

19 9.2 Note

9.2.1 The recommendations given in this report have been arrived at on the basis of design

parameters which have been judiciously adopted by giving due consideration to the results

of field and laboratory investigations as well as NAGADI’s experience of over four

decades in working in various types of soil and rock conditions all over India.

10.0 CONSTRUCTION ADVISORY

10.1 The soil of each strata has been described with name, colour etc. During excavation any

variation in the nature of the soil and its condition from those given in this Report should

be noted and appropriate action should be taken.

10.2 The excavated soil can be used for backfilling purposes.

10.3 The minimum width of foundation for isolated foundation is 1.5m and that for strip

foundation is 1.2m.

10.4 After the excavation, If loose pockets of weathered rock are encountered they may be

backfilled with lean concrete and the foundations can be subsequently be placed.

The foundations may be layed at different levels as weathered rock strata is encountered

at different depths. The foundations should be as per IS 1904 -1986.

10.5 There are wells located in the site. In case, the wells are not utilised, they can be closed

by back filling with sand-gravel mix. The back filling should be done in layers and well

compacted. Incase, the wells are to be utilised, the sides should be properly lined. Also the

distance of the nearest footing to the wells should not be less than 1 to 1.5 times the width

of the foundation.

ENVIRONMENT MONITORING PLAN

Environmental Monitoring Plan

The environmental monitoring to be carried out at the project is discussed below:

Monitoring and Reporting Procedure

Regular monitoring of important and crucial environmental parameters is of immense importance to assess the status of environment during the construction as well as operational phase. With the knowledge of baseline conditions, the monitoring program can serve as an indicator for any deterioration in environmental conditions due to operational phase and suitable mitigatory steps could be taken in time to safeguard the environment. Monitoring is as important as that of control of pollution since the efficiency of control measures can only be determined by monitoring. The following routine monitoring program will be implemented under the post project monitoring. The proposed monitoring program is given below:

 Air Pollution Monitoring

Both ambient air quality and stack emissions shall be monitored. The ambient air quality shall be monitored once in three months in the work zone, at the DG set location and surroundings through a reputed environmental laboratory recognized by TNPCB/MoEF. Similarly, the stack monitoring shall be carried out once in three months and the results shall be reported to pollution control authorities.

 Wastewater Quality

The sewage emanating from the office buildings shall be monitored once in a month for physico-chemical characteristics.

 Noise Levels

Noise levels near the DG sets shall be monitored once in three months.

Safety Plan

Safety of both men and materials during construction and operation phases is a cause of concern. The preparedness of the institution for any eventual disasters is known as emergency plan. Keeping in view the safety requirement during construction, operation and maintenance phases, and the management will follow the recommendations given below:

 Allocate sufficient resources for safe and healthy conditions at work places;  Take steps to ensure that all known safety factors are taken into account in the design, construction, operation and maintenance;  Ensure that adequate safety instructions are given;  Provide wherever necessary protective equipment, safety appliances and clothing, and to ensure their proper use;  Provide appropriate facilities for first aid and prompt treatment of injuries and illness at work;  Provide appropriate instructional training, retraining and supervision to residents in health and safety, first aid and to ensure that adequate publicity is given to these matters;  Ensure proper implementation of fire prevention methods and an appropriate fire fighting service together with training facilities for personnel involved in this service.
