ENVIRONMENTAL MANAGEMENT PLAN

1 Introduction

The Environmental management plan (EMP) is necessary to ensure sustainable development

in the area of the proposed project. Hence it needs to be an all encompassing plan for which the

Industry, Government, Regulating agencies likes pollution control board working in the region

and more importantly the population of the area need to extend their co-operation and

contribution.

It has been evaluated that the project area will not be affected significantly with the proposed

project. Mitigation measures at the source level and an overall management plan at the site level

are elicited so as to improve the surrounding environment.

The following mitigation measures are recommended in order to synchronize the economic

development of the project area with the environmental protection of the region. The

construction phase impacts are mostly short term, restricted to the plot area and not envisaged on

the larger scale. In the operational phase the environmental impacts are due to continuous

operation of the project, hence, the emphasis in the environment management plan (EMP) is to

minimize such impacts. The emphasis on the EMP development is on the following:

Mitigation measures for each of the activities causing the environmental impact

Monitoring plans for checking activities and environmental parameters and

monitoring responsibilities.

Role responsibilities and resources allocation for monitoring.

Following sections describes the environment management plan proposed for construction and

operation phases.

1.1 Management during Construction Phase

In the impact assessments following four activities have been identified as causing impact of

different degrees on the environment during construction phase:

1. Site clearance

2. Transportation of construction materials

3. Construction activity

4. Labour camps of construction workers

1.2 Mitigation measures


Balaji developers

Each of the above activities during construction phase is critically reviewed for suggestion of

mitigation measures. Based on this, the Table 1.1 to 1.4 gives the mitigation measures for the

activities considered to be causing significant environmental impacts during construction phase.

In general the best housekeeping practices are incorporated in the design as well as construction

phase to reduce the short terms impacts due to construction activities.

TOTAL NO OF PERSONS

Number of abodes planned 125 Apartments

Total No of Persons = 625

Water requirement per capita per day = 125 x 135 = 84100 Liters= 84 KLD

Total Water requirement = 84 KLD

Total quantity of domestic sewage generated = 67 KLD

Sewage Treatment plant designed for the proposed Site - = 70 KLD


Balaji developers

1.3.3 SEWAGE TREATMENT PLANT

The design is made keeping in mind the total quantity of generation of 67000 lts per

day. The modular technology is adopted in the design, i.e. when the flow increases drastically,

the present units itself can be used with additional units attaching to it in modules, which would

be economical and saves on the area required too.

Characterization:

The general characteristic of untreated and treated sewage is considered as shown in the

table below.

Parameters Before Treatment After Treatment

pH 6.0 to 8.0 7.0 to 7.5

Suspended Solids 250 to 400 < 20

BOD 200 to 300 < 10

COD 400 to 600 250

Residual Chlorine > 1

Mode of Treatment:

It is proposed to set up a treatment plant for treating the domestic waste using the tested

and trusted activated sludge process with extended aeration through diffused aeration. The other

modes of treatment considered before arriving at activated sludge process are SAFE (Submerged

aerated fixed film reactor), SBR (Sequential Batch Reactor), RBC (Rotary Biological

Contractor). The advantages and disadvantages of the each scheme, initial investment and

maintenance cost etc were compared and finally arrived at the activated sludge process.

1.3.4 SOLID WASTE MANAGEMENT

A. Solid waste consist of

1. Garbage

2. Ashes

3. Rubbish

4. Dust Etc.

Solid waste is broadly divided into

1) Organic or combustible matter.

2) Inorganic or mineral or non- combustible matter.

The solid waste generated during operation phase can be categorized under three types:

Domestic/Residential waste

Wet Garbage: Food waste, Lawn mowing wastes etc.

Dry Garbage: Paper, plastic, Bottles, etc.

Sludge from sewage Treatment Plant (STP)

The solid waste generated in the premises is estimated to be about 281.25 Kg/d, which will be

sent to proposed composting unit for further processing, Reusable items such as plastic bottles,

cold drinks, Meta/Glass containers, etc are sold to Recyclers.


Balaji developers

The various mitigation measures to be adopted during collection and disposal of wastes are as

follows:

It is preferable that the container and bins used for collection of waste should be of closed

type of that the waste is not expected and thus the possibility of spreading of disease

through flies and mosquitoes is minimized.

Collection system should be properly supervised so that quick and regular removal of

waste from the dustbin is practiced.

Door to door collection will be arranged in each commercial unit to collect the solid

wastes. The biodegradable wastes will be segregated and sent to the proposed composting

unit. Non-biodegradable wastes such as plastic materials, glass & metal wastes will be

handed over to the waste recyclers.

About 750 Liters of waste oil per year will be generated from standby DG sets. This will be

stored in leak-proof sealed barrels and will be given to KSPCB authorized waste oil re-

processors.

1.3.4 Noise Level Management

High noise generated units such as DG set will be provided with acoustic enclosures. Green belt

on the project boundary will further act as noise barrier and helps in attention of noise.

Following Table – 1.8 presents the EMP for noise levels.


Balaji developers

Table: 1.8

MANAGEMENT OF NOISE LEVELS DURING OPERATIONAL PHASE

Environmental

Mitigation

Noise from DG

set area

DG set will be installed in an area (Utility section ) where the access

will be restricted

The use of PPD ( ear plugs) will be mandatory is this area selection

of equipment to ensure that the residual noise level of 75 dB ( A )

Noise levels will be checked periodically using a noise pressure

level meter

1.4 Green Belt Development

Green belt development (1431.55 Sq m) within the premises will reduce noise levels and dust

levels. To make the green belt effective for this purpose, it is essential to select proper plant

species and design the plant and row spacing that result in lowering the sheltering effect. In the

development of green belts multipurpose plant species should be selected. This will satisfy the

ecological requirement for species diversity.

1.5 Storm Water Disposal through Rain Water Harvesting

Rain water from roof tops, balconies etc. is allowed to flow through down take pipes that are

sloped to the concealed storm water collection tanks. This water can be used for house gardening

and for other domestic purpose for washing vehicles, etc.

Rain water from other sections of the site is led to catchments pit at each change in flow

direction and at each change in pipe diameter with horizontal & vertical grating depending upon

the road section.

Design of piping network is done on the basis of:

Site Topography & Effective Area

Sizing by Rationale’s Formula with full running pipe

Run-off Coefficient


Balaji developers

Rain water from all the roads is routed to the side drains on either side of the road which is

designed as per the Metrological report; intensity of rainfall is taken as 75mm – 100mm per hour.

Percolation pits can be provided below the tank bed of the collection tanks, thereby recharging

the ground water table as well.

Rain water harvesting will be done by both collection for reuse and ground water recharge.

For assessing the available quantum of water it is assumed that incidental rain fall less than 10

mm will not yield any collectable yield and such rain fall account for 50% of the total rainfall.

The runoff coefficient 0.9 for impervious surface, 0.7 for roads and driveways 0.55 for pervious

surfaces like gardens and soil surfaces is considered, duly accounting for evaporation, seepage

etc.

Rain Water Harvesting:

Rain fall & Yield from terrace

Annual average rain fall = 975 mm

Hence co-efficient of run off will be 0.9

Yield Available = 0.975 x 0.9 x 1645

= 1405 cum

Rain fall & Yield from driveways



Yield Available = Area x 0.975 x 0.7

=1301 x 0.975 x 0.7

= 865 cum


Balaji developers

Rain fall & Yield from green way runoff



Yield Available = Area x 0.975 x 0.55

=1431 x 0.975x 0.55

= 680cum

The Rainfall harvesting potential for the project is collectively 2950 cum annually. Which can

cater the needs for about 53days.

Rain water harvesting is proposed by means of

1. Collection tank of 100cum x 1no.s

2. Infiltration galleries of 0.45m x 0.45 m in the bed of storm water drain.

3. Recharge pits of 2M X 2M in open spaces. 21in No.

Mode of Usage of rain water:

The Ground water will be recharged through 21 No. of percolation pits. Each pit has a

capacity to absorb in excess of water. The balance water will be collected in two tanks of 1.0 ML

capacity each. The water collected in rainwater collection sump will be used for car washing

purposes after passing through the pressure sand and the activated carbon filter of diameter 650-

mm each.

Mode of usage of water incase of sudden flash floods / continuous rains: though the rainy

days are considered as 120 days in Bangalore and the total rain is divided by the no. of rainy

days, practically the intensity of rain is not the same every day. It varies from day to day. Incase

when there is a heavy and flash rain, the excessive rainwater is led into the existing municipal

storm water drain.

The primary purpose of the on-site emergency plan of DMP is to control and contain the incident

and so to prevent if from spreading. It is not possible to cover every eventuality in the plan and

the successful handling of the emergency will depend on appropriate action and decisions being

taken on the spot. Other important aspects needing to be considered include the following:

8.3 Emergency

A major emergency in any situation is one, which has the potential to cause serious injury

or loss of life, which may cause extensive damage to the structures in the vicinity and

environment and could result in serious disruption to normal operation both inside and outside

the layout premises. Depending on the magnitude of the emergency, services of the outside

agencies may also be required for supplementing the internal effort to effectively handle the

emergency and to contain the damage.

The Management has to take effective steps to assess, minimize and wherever feasible

eliminate the risks to a large extent. Accidents may still occur and it is necessary to be fully

prepared to tackle all such emergencies if and when they occur.

It is likely that the consequences of such emergencies will be confined to the units

concerned or may affect outside. If the consequences are confined within the plant boundary, it is

then termed as on site Emergency and will be controlled by chief emergency controller.

In order to generate the plans it is necessary to first determine the kinds of accidents

leading to an emergency that can occur in the layout. The most widely used technique in practice

is based on experience accumulated over many years and safety audits.

A. Methodology

The considerations in an emergency planning include the following:-

Identification and assessment of hazards and risks.

Hazard, consequence analysis

Alarm and communication procedures

Identifying, appointment of personnel & assignment of responsibilities

Identification and equipping emergency control center, identifying Assembly, Rescue

points, Medical facilities.

Emergency preparedness plan, procedures, steps to be taken before, during and after

emergency.

Formulation of plan and emergency sources.

Training rehearsal, evaluation and updating the plan

B Structure of Emergency Management

a) Nothing the accidents

b) Informing declarer of emergency

c) Declaration of emergency

d) Functions of declaration

e) Interaction with outside agencies

C Identification and Assessment of Hazards

This stage is crucial to both on-site and off-site emergency planning and requires

systematic identification of all possible emergencies that could arise in the plants. These should

range from small events, which can be dealt by plant personnel without any help from external

agencies to the largest event that would require outside help. The tackle such emergencies

effectively, it is essential to have clear-cut action plan. Experience has shown that for every

occasion that the full potential of an accident is realized, there are many occasions when some

lesser event occurs or when developing incident is made safe before reaching full potential.

D Infrastructure at Emergency Control Center

Emergency control centers should therefore contain the following

An adequate number of external telephones; if possible, one should accept


Balaji developers

Only outgoing calls, in order to bypass jammed switchboards during an

Emergency.

A adequate number of internal telephones

Radio equipment

A plan of the works, to show:

Areas where there are large inventories of hazardous materials.

Sources of safety and first aid equipment.

The fire-fighting system and additional sources of water.

Site entrance and roadways, including up-to-date information on road

Traffic.

Assembly points.

Vehicle parking and rail sidings.

Additional work and layout plans detailing alternate routes and affected area,

during an emergency.

Note pads, pens and pencils.

A nominal role of employee.

A list of key personnel, with addresses, telephone numbers, etc.

The emergency control center should be sited in an area minimum risk. Suitable location from

where clear view of the plant is possible or the control room can be designated as emergency

control center. All the site controller/ Incident controller officers, senior personnel would be

located here or have access to the ECC.

E. Emergency Medical Facilities

Stretchers, gas masks and general first aid materials for dealing with chemical burns, fire

burns, etc., would be maintained in the medical center as well as in his emergency control room.

A range of medicines should be maintained in the ECC/ medical center. Breathing apparatus and

other emergency medical equipment should be provided and maintained.

The medical center should display poster for treating burns and first aid. Some medicines

and facilities to be kept in the medical center are suggested. The list is indicative and the

qualified doctors of the medical center should use their professional judgment for medical

treatment.

F Health and Safety Measures for the Workers

a. Buildings and Structures: No walls, Chimneys, Galleries, Stairways, floor,

platform, staging or structure whether of a permanent or temporary character shall

be constructed in such manner as to cause risk or bodily injury.

b. Provision of crawling boards etc: No person shall be required to stand to pass

over on or near by any roof of ceiling cover with fragile material through which he

is liable to fall, in case it breaks or gives away the distance for more than 3 meters

without use of sufficient number of suitable ladders, duck ladders or crawling

boards which are securely supports.

c. Service Platforms: Whenever practicable and demanded service platforms

and gangways will be provided for overhead shafting, and where required by him

these will be securely fence with guard rails and toe boards.

d. Belts, etc: All belts will be regularly examined to injure that the joints are safe

And the belts are proper tension.

e. Helmets: Helmets will be provided to the workers for safe guarding themselves

Against any head injuries.

f. Machinery: No machineries are equipments will be situated, operated or

Maintained in such a manner as to cause risk of bodily injury.

g. Methods of work: No process of work will be carried out in such a manner as

To cause risk of bodily injury.

h. Electricity: No electricity installation shall be provided during construction so

As to be dangers to human life or safety.

i. Medical Check-up: Medical examination every worker shall be examined by

Certified surgeon at least once in 3 months of a calendar.

G. Emergency action plans

a. Emergency Action Plan for Cylinder Fire:

1. When filled container containing LPG is involved in fire, internal pressure if not relieved,

shall build up above 70KG/SQCM and ultimately rupture the container. Rupture weak by

direct flame impingement. Ruptured containers can be propelled at distance by jet action.

2. If container’s pressure is not raised upto 70KG/SQCM leakage from screwed valve joint

can occur due to different expansion of steel and brass.


Balaji developers

3. Ignition of the escaping gas would aggravate the fire but release of fire reduces the

possibility of rupture.

4. No attempt should be made to extinguish the burning gas but the container under fire and

other containers in vicinity should be kept cool by water spray.

5. If the gas leakage does note ignite, the container should be approached from up and

removed to the place of safety away fro, the source of ignition.

b. Emergency Action Plan for Electric Fire:

1. Disconnect the affected areas electric supply.

2. Attempt to extinguish fire with the help of Co2, DCP.

3. If fire is not extinguished, extinguish by spraying water with fog nozzle after ensuring

complete isolation of electric circuit.

c. Emergency Action Plan for Office Fire:

1. Disconnected electric supply of the affected area.

2. Attempt to extinguish the fire with the help of Co2, DCP and sand.

3. If large fire, use hydrant system.

4. Attempt to save the record.

5. Attempt fire extinguisher.

d. Emergency Action Plan for Oil Fire:

1. Attempt to extinguish small fire with the help of DCP

2. If the fire is not controlled, use water foam to blanket the fire and further action is to be

taken.

e. Emergency Action Plan for Medical Aid:

f. Emergency Action Plan for Electric Shock Casualties:

Electric Shock results in:

Irreversible damage to brain cell begins followed by deterioration of the organs.

Rescue and first aid:

Do first aid quickly and without fuss and panic.

Switch off the supply if this can be done at once.

If not possible use a dry stick, dry cloth or other non-conductor to separate the victim

from electrical contact.


Balaji developers

The reducer must avoid receiving shock himself by wearing gloves or using a jacket to

pull the victim.

Always keep in mind that delay in rescue and resuscitation may be fatal. Every sound

counts.

ii. Artificial Respiration: Give artificial respiration if breathing has stopped. There are several methods of artificial

respiration, if the victim is nit injured over the face, try mouth to mouth.

a) Mouth to Mouth Method:

If there is obstruction to breathing, remove it with your fingers if it in mouth. Several

sharp blows between shoulder blade may help to is lodge an obstruction.

Lie casually on his back, put something under his shoulder to raise them & allow his

head to fall backwards. The head should be, if possible be a little lower than the trunk.

Remember that speed is essential.

Kneel at the causalities head and grasp his arms at the wrists then cross them firmly

over the lower chest. This movement should force air out of his lungs. Press with the

hands crossed on the lower part of the chest and maintain pressure for two seconds.

Release this pressure and pull out his arms with a sweeping movement upwards and

outwards above his head and backwards as far as possible.

This movement should cause air to be drawn in to his lungs. Retain the arms in this

position for three seconds.

Repeat these movements rhythmically about twelve times a minute checking the mouth

frequently for obstructions. Each cycle will thus take give seconds- two seconds for

hest pressure and three seconds for arm lift.

With the causality on his back there is danger of aspiration of vomit, mucus or blood

reentering the system. Keeping his head extended and a little lower than the trunk can

reduce this risk.

If an assistant is available, he can press the causality lower jaws so that the chin is

jutting out.

The assistant should also ensure that the mouth is kept open as far as possible and head

is tilted to one side.

When natural breathing begins, your movement should be adapted to correspond to it.

If burns are present, cover them with a dry sterile dressing

Handle the causality gentle

Do not allow people to crowd around and block fresh airflow

Arrange to remove the injured to the care of a doctor ad early as possible.

f. Natural Hazards

i. Emergency Action Plan for Tornado/High Winds:

a. Weather reports shall be monitored from broadcast warnings threatening conditions.

b. If the tornado has been sighted or effect is felt, following steps should be taken by plant

personnel.

Persons shall be notified over public address system or through siren.

Emergency services shall be alerted for assistance.

Plant personnel should be advised to assemble in the administration building

basement, staff room, recreation room and rest rooms.

All safety systems should be kept on alert and all nonessential utilities should be

put off.

After the status is restored, personnel should inspect all the facilities for resource,

first aid and damage control activities, damage assessment, and clean up,

restoration and recovery.

ii. Emergency Action Plan for earthquakes

a. When first tremors are sensed during an earthquake, all personnel should evacuate

Buildings and assemble at safe place away from structures, walls and falling objects.

Emergency shut down should be declared.

b. Emergency services should be contacted for assistance.

c. After the status is restored, personnel should inspect all the facilities for rescue,

First aid and damage control activities, damage assessment, cleanup, restoration and

Recovery.

9.1 Construction Phase

The number of concrete mixers, cranes, transport vehicles, etc. should be kept to an

optimum level to minimize risks of accidents.

Temporary colonies of the work force etc should have proper sanitation including toilets

and bathrooms. Sewage and other wastes generated in these settlements should be

collected and disposed of in an environmental friendly manner.

The construction noise level should be kept to a minimum particularly during the

excavation and slab construction.

The dust generation should be controlled by water sprinkling at regular interval at the site

and nearby roads.

Dedicated driveways should be marked for movement of construction equipments and

vehicles.

All personnel working at the site should be properly trained in safety procedures needs to

follow.

The personnel should also be trained in the operation of fire fighting machineries.

The personnel should also be made aware of the importance of wearing personal

protective equipments at all times as directed by their supervisor.

9.2 Operational Phase

Utilizing the experiences gained by the local environment during the construction period should

assemble a plan of action for mitigating the predicted adverse effects.

a. Traffic Control

Speed limit of 20 Km/h should be specified for roads within the premises

The separation of pedestrian movement and vehicular traffic should be strictly enforced.

b. Solid Waste

All House keeping persons working in the BALAJI DEVELOPERS must be trained to

segregate the bio-

Degradable waste from the non-bio-degradable waste, so that the quantity which requires

To be disposed off through vermin composting or any other safe method of disposal,

Thereby reducing the load on environment.

Good housekeeping practices should be maintained which helps in prevention of

contamination of soil through improper spillage of solids wastes and other materials.
