2.3 CLIMATIC CONDITIONS

The city of Bangalore experiences a very favourable weather throughout the year.

The city is located in the Deccan plateau of southern peninsular India. The warmest

month in Bangalore is April and the coldest month is January. The climate in

Bangalore is basically dry tropical savannah climate.

Bangalore always experiences a very soothing weather with warm summers and

cold winters. But neither the summers are very hot, nor are the winters very cold.

Rainfall takes place quite often. Bangalore witnesses the south-western monsoon

rains. The average annual rainfall in Bangalore is 930 mm, and the rainy season

starts from July to September.

The maximum temperature level at the summer time can rise to 36°C whereas those

during winter can even go below 17°C. The weather in Bangalore is neither too

humid nor too dry. The weather becomes foggy in the early mornings of October to

February which is the maximum in the months of December and January. The

climatic condition in Bangalore is very much influenced by the low cloud during the

months of June to September.

The city has still preserved much of its green cover compared with other Indian

cities. The region is characterized by limited presence of species of Flora, fauna,

Avifauna and Aqua fauna due to intensive industrial, commercial and residential

development.



2.4 SEISMICITY

The seismic hazard map of India was updated in 2000 (5) by the Bureau of Indian

Standards (BIS). According to the new map, the state of Karnataka lies in Zones II

and III. The coastal districts as well as the northern interior districts along the border

with Maharashtra, lie in Zone III, where a maximum MSK intensity of VII can be

expected. The remaining districts, as well as the city of Bangalore lie in Zone II.

PREDICTION OF IMPACTS &

ENVIRONMENTAL MANAGEMENT PLAN

4.1 GENERAL

Prediction of impacts is a significant component of

the Environmental Impact Assessment of any

project. Several scientific methods are available to

predict impacts of development projects on air,

water, ecological & socio-economic environments.

Such predictions are superimposed over baseline

environment status to derive post project scenario

of environmental conditions. The prediction of

impacts helps to minimize adverse impacts on

environmental quality during & after project

execution by suitably designed environment

management plans.

Environmental Management Plan (EMP) consists of all mitigation measures for each

item wise activity to be undertaken during the construction, operation and the entire

life cycle to minimize adverse environmental impacts as a result of the activities of

the project.

This section outlines the key Environmental Management and safeguards that will be

initiated by the project proponent to manage the project’s key Environmental

concerns. EMP is the tool for mitigating or offsetting the potential adverse

environmental impacts resulting from various activities of the project.

The potential environmental impacts and proposed management associated with

each stage of the project development are described here. The primary objective of

this proposed environmental management plan is to control environmental impacts

to levels within acceptable limits and to minimize possible impact on the community

water down take pipes and connected to catch basins. The rain water from

hardscapes and landscapes will be collected by catch basins through drains with

gratings and connected to the storm water channels. The overflow from these would

be drained into sumps located in the underground from where water will be

pumped out to the external storm water drain. Also it is proposed many rain water

recharge pits at suitable distances surrounding the project periphery.

The details of rainwater harvesting are provided in Annexure – 2.

4.3.8 Energy Conservation Plan

The energy consumption analysis and data sheets are as per the Energy

Conservation Building Codes 2007 / Bureau of Energy Efficiency.

Various energy conservation measures to be adopted in the proposed project are

described below:

4.3.8.1 Solar Architectural features

The proposed project will be provided with enough daylight factors in the building

to permit maximum daylight to the interior to minimize overall energy

consumption. These features will also minimize the impact of climate both in

summer and in winter and as a result, the use of electricity is likely to be reduced.



4.3.8.2 Energy saving measures

Energy efficient appliances will be installed in the building.

Constant monitoring of energy consumption and defining targets for energy

conservation will be employed.

Sunscreen films on windows to reduce heating inside the buildings will be used.

All lifts are proposed on VFD drives which results in 30% saving in consumption.

Most of the common area lighting is proposed to work on high energy efficient

lamps (LED) as specified in bureau of energy efficiency, which again results in

saving in general consumption. The LPD is working less than 1W/ m2.

External street & landscape lighting is assumed to be 30KW. 30% of the external

lighting is proposed on solar. These are set of lighting which are placed at critical

junctions and which would be lit round the night.

All internal common area lighting system is proposed to have either high

efficiency lamps/ LED. These give us a LPD less than 6.0W/m2 but still achieving

the required 200 LUX for ambient lighting.

The stilt ground floor shall have timers to reduce the number of lights working

during non peak hours 50% only drive way is ON and other can parking lights

can OFF during non peak hours and late night @0.95.

To achieve maximum savings 70% of external lighting shall be controlled by a

photo sensor or timer circuits that is capable of automatically turning off the

external lighting when daylight is available or lighting is not required.

Power factor corrections With APFCR based system for Capacitor banks for all the

Common area loads there by maintaining the Power factor (P.F) @0.95& unity &

reducing the power losses.

Check-Metering and Monitoring: All Common area Services & Club house

services shall have permanently installed electrical metering (Max demand meter)

to record demand (KVA), energy (KWH), and total power factor. The metering

shall also display current (in each phase and the neutral), voltage (between phases

and between each phase and neutral), and total harmonic distortion (THD) as a

percentage of total current.



As an addition energy conservation plan, the project is proposed to implement

solar harvesting methods like solar water heaters.

4.3.8.3 SAVINGS IN ELECTRICAL POWER CONSUMPTION

The proposed project will be implementing all the possible energy conservation

measures in order to reduce the burden on non renewable sources and increase the

implementation/extraction of energy from renewable resources like solar energy,

wind energy etc... Along with the measures to reduce the energy consumption by

using best available energy efficient/green technologies. The overall proposed

energy savings from the following methods will be about 20% savings.

Table 12 : Savings in electrical power consumption

4.3.9 Fire safety and Protection

15. To render necessary help to the concerned.

16. To rehabilitate the area affected.

17. To provide information to the media & government agencies.



5.2.2. Scope of Onsite Emergency Plan

The plan covers information regarding the properties of the residential apartments,

type of disasters and disaster/accident-prone zones, the actual disaster control plans

with authority delegation, controlling and other details. General details like location,

project layout, neighboring entities and the assistance they can render etc., are also

provided.

The important elements considered in this plan are

Statutory requirements

Emergency organization

Roles and Responsibilities

Communication during emergency

Emergency shutdown & control of situation

Rescue & Rehabilitation

Emergency facilities

Important Information

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

the incident and so to prevent it 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:

5.3. 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 the

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.

5.3.1. Methodology

The considerations in an emergency planning include the following: -

1. Identification and assessment of hazards and risks

2. Hazard, consequence analysis

3. Alarm and communication procedures

4. Identification and appointment of personnel & assignment of responsibilities

5. Identification and equipping Emergency control centre, Identifying Assembly,

Rescue points, Medical facilities.

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

after emergency.

7. Formulation of plan and emergency sources.

8. Training rehearsal, evaluation and updating the plan

5.3.2. Structure of Emergency Management 1. Noticing the accidents

2. Informing declarer of emergency

3. Declaration of emergency

4. Functions of declarer

5. Interaction with outside agencies



5.3.3. 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. To 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.

5.3.4. Infrastructure of Emergency Control Centre

Emergency control centres should contain the following:

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

outgoing calls, in order to bypass jammed switchboards during an emergency.

An adequate number of internal telephones

Radio equipment

A plan of the works, to show:

o Areas where there are large inventories of hazardous materials.

o Sources of safety and first aid equipment.

o The fire-fighting system and additional sources of water.

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

traffic.

o Assembly points.

o Vehicle parking and rail sidings.

o Additional work and layout plans detailing alternate routes and affected

areas, during an emergency.

o Note pads, pens and pencils.

A nominal role of employees.

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

The emergency control centre should be sited in an area of minimum risk. Suitable

location from where clear view of the plant is possible or the control room can be



designated as Emergency Control Centre. All the Site Controllers / Incident

Controller Officers, Senior Personnel would be located here or have access to the

ECC.

5.3.5. 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 centre as well as in the

Emergency Control Room. A range of medicines should be maintained in the ECC/

Medical Centre. Breathing apparatus and other emergency medical equipment

should be provided and maintained.

The Medical Centre should display poster for treating burns and first aid. Some

medicines and facilities to be kept in the medical centre are suggested. The list is

indicative and the qualified doctors of the medical centre should use their

professional judgment for medical treatment.

5.3.6. Health and Safety Measures For the workers i. 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.

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

over or work 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 the use of sufficient number of suitable ladders, duck ladders or

crawling boards which are securely support.

iii. 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.

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

the belts are proper tension.

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



against any head injuries.

vi. Machinery: No machineries or equipments will be Situated, Operated or

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

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

cause risk of bodily injury.

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

as to be dangers to human life or safety.

5.3.7. Emergency action Plans

5.3.7.1. 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/sq.cm 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 70 kg/sq.cm leakage from screwed

valve joint can occur due to different expansion of steel and brass.

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 not ignite, the container should be approached from

up and removed to the place of safety away from the source of ignition.

5.3.7.2. 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.

5.3.7.3. Emergency Action Plan for Office Fire:



1. Disconnect electric supply of the affected area.

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

3. In case of large fire, use hydrant system.

4. Attempt to save the record.

5. Attempt fire extinguisher.

5.3.7.4. 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

5.3.7.5. Emergency Action Plan for Medical Aid:

1. Emergency Action Plan for Electric Shock Casualties:

Electric shock results in irreversible damage to brain cells 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.

The rescuer 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 second counts.

Artificial Respiration:

Give artificial respiration if breathing has stopped. There are several methods of

artificial respiration, if the victim is not injured over the face, try mouth to mouth.



i) Mouth to mouth Method:

If there is obstruction to breathing, remove it with your fingers if it is in the

mouth. Several sharp blows between shoulder blade may help to dislodge 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 arm 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 chest pressure and three seconds for arm lift.

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

blood re entering the system. This risk can be reduced by keeping his head

extended and a little lower than the trunk.

If an assistant is available, he can press the causality’s 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 gently.



Do not allow people to crowd around and block fresh airflow.

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

5.4 Natural Hazards 5.4.1. Emergency Action Plan for Tornado/High Winds:

a. Weather reports shall be monitored from broadcast warnings regarding

threatening conditions.

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

the 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.

5.4.2. Emergency Action Plan for earthquakes a) When first tremors are sensed during an earthquake, all personnel should

evacuate the buildings and assemble at a safe place away from structures, walls

and falling objects. Emergency shutdown 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.

5.4.3. Emergency Action Plan for Bomb Threat

When bomb threat call is received the following measures are to be taken.

Inform the message to the highest local police authority and seek their assistance



for patrolling and security need.

Inform Controller of Explosives the details and nature of the anonymous message

and read operations.

1.0 Executive Summary

1.1 Introduction

The proposed project site area is currently been used as stock yard of Vizag Steels.

As the proposed site is located in the midst of the Hoodi business town, it’s been

very difficult to carry out the current activity, mainly because the present activity

involves the movement of heavy transport trucks, which has lot of traffic

restrictions. Hence the present steel stockyard is being shifted to outskirts of the

city, so as to ease the situations. So the proposed site will be developed by

M/s Godrej Housing Projects LLP, a subsidiary of Godrej Properties Limited, a

leading real estate industry. Godrej Properties Limited has completed several

landmark projects and the company is currently developing landmark projects in

12 cities across India. Established in 1990, it is the first real estate company to have

ISO certification. With projects that span across the country, the company's

upcoming development covers over 8 million square meters. To create landmark

structures, Godrej group collaborates with outstanding associates and reputed

names. The company aims to deliver superior value to all stakeholders through

extraordinary and imaginative spaces created out of deep customer focus and

insight.

The Company has proposed a new residential apartment buildings project at

Survey Nos. 13/6, 14/1, 16/4 & 16/5 of Hoodi village, K.R. Puram Hobli,

Bangalore East, over an area of 5 Acre 12 Guntas (21448 Sqm), and the company is

proposing to change the current land use from industrial to residential.

1.2 About the past activity

The project site is presently used as the stockyard for Vizag Steels. The main

activity in the site is receiving of the steel from Vizag steels & to store the same for

further delivery/distribution to the customers. The final products from Vizag Steels

such as Wire Rod Coils, TMT bars, Automobile shafts, and other steel and Iron

products are stored for distribution. The present activity mainly includes loading



and unloading of the products, unwinding and straightening of coils and cutting

them into desired length for retail purposes. Then the products will be transported

in heavy trucks.

2.3 Site Sensitivity

The Project site is located along the Hoodi Main Road, K.R Puram Hobli, Bangalore

East, Karnataka. It adjoins the Commercial & Residential development areas. There

was no ecologically sensitive area in close vicinity; the site had limited potential for

ground water contamination because of the soil formations are characterized by

Silty Sand/Sandy Silt with clay occurring as an interstitial binder.

3.0 Anticipation of the project

3.1 Audit Objective

The main objective of the environmental, health and safety Due Diligence Report

(DDR) is to:

Identify any environmental/health and safety liability issues, and any

environmental and worker health and safety risks associated with past

operation of the plant, particularly issues related to accident prevention,

dangerous working conditions, air pollution and soil/ground water

contamination.

Perform an environmental analysis to describe the planned upgrades, their

environmental, health and safety impacts and their ability to conform to set

up of the upcoming project.

Prepare an Environmental Action Plan (EAP) to address any non-compliance

to establish the upcoming project.

The findings of the audit are documented in this report and recommendations

are given in the EAP, including need for improvement of management,

technical issues and requirement for further investigations.

3.2 Audit Methodology

The review focuses on screening for the potential sources/units of the

contaminants, any suspects of the contamination from the activity, confirms

through investigation and analysis, for the past activity at the project site and future

compliance of the Proposed Construction activities of the M/s Godrej Housing

Projects LLP.



When undertaking, the audit, the key risk indicators that were considered

included

Past potentially polluting activities, including the scale, extent and duration of

activities;

Past use of substances with the potential to cause harm to human health and

the environment;

Proximity of human receptors, for example, residential areas;

Nature of the surrounding land-use with respect to the impact the facility

could have had/could have in terms of human health, crops, domestic

animals, etc.;

Groundwater vulnerability. This relates to the potential for pollution of the

soil and thus groundwater beneath the facility.

Proximity of surface water courses;

Use of proximal water courses, for example, for potable supply, irrigation,

watering farm animals.

Quality of surface water courses;

Proximity of ecological receptors which could impacted by contamination

migrating from the facility;

Past and recent pollution events;

Perceived risk of future environmental non-compliance

Perceived risk of future occurrence of pollution events:

Health and safety incidents and accidents; and

Health and safety claims made against the company

The review of the facility involved discussions with senior and technical

management, a walkthrough of the facility and a review of any relevant

documentation made available to us. These reviews are intended as top level

reviews and did not involve great detail. Additionally the reviews did involve

intrusive sampling or analysis.



The reviews addressed the following:

Background and history of the site.

Broad review of past process technologies and operating practices.

Impact prediction of process units.

Review of environmental management practices.

Existing water discharges and air emissions.

Solid waste management and identification of significant waste streams.

Description of waste, chemicals, fuel, and other storage areas.

Occupational health and safety issues.

Emergency response.

Public interaction, including historical responsiveness to public

comments, complaints and questions.

Identification of any potential liabilities which may affect the Company e.g.

soil and ground water contamination as a consequence of past

operations, presence of PCBs in oil filled transformers, etc.

Proximity to environmentally sensitive areas on which the facility might

impact.

4.1 Process Methodology

The main activity carried out at the stockyard is storage and distribution of the steel

products of Vizag steels. The steel coils will be straightened to desired length and

made as TMT rods and delivered for the customers.

4.2 Disposal of solid waste

The main solid waste generated from the activity is the metal/steel scrap, which is

stored in a designated area and regularly sold to the authorized scrap dealers

through tenders. This in turn will be recycled for other product.



4.3 Environmental Impact Issues

The storage and handling of steel doesn’t cause any potential environmental

impacts. The only impact caused is due to the movement of trucks producing dust

and other emissions, which may affect the health and well being of the workers in

close proximity.

5.0 Site Investigation

5.1 Previous investigations and reports

Before starting construction works soil investigations have been performed. Results

of these investigations indicated that the soil formations are characterized by Silty

Sand/Sandy Silt with clay occurring as an interstitial binder.

5.2 Risk of Possible Impacts

5.2.1 Regional Geology

Geo-morphologically, Bangalore district can be divided into rocky upland, plateau

and flat topped Hills at an elevation of about 900m above MSL (Mean Sea Level).

Major part of district lies in Cauvery river basin over an area of 5450 km covering

nearly 68% of the total area. Major tributaries of Cauvery draining the district are

Kanva, Shimsha and Arkavathy. Other rivers draining the remaining part of district

are Pennar, Palar and Ponniyar. Soils of Bangalore can be broadly classified into

three categories (viz.) Loamy (silt dominated) Soil, Lateritic Soil and Lateritic

gravelly soil depending upon parent rocks in that area. These soils show vide

variation in overburden thickness. Below this layer occurs weathered rock exhibiting

varying degree of weathering (degree of weathering generally decreasing with

depth). Further below, Precambrian crystalline rock formations, mainly peninsular

gneissic complexes with a small patch of hornblende schist in Northern part

of District and intrusive closepet granite all along the western parts of the district.

Small stretch of unconsolidated sediments is also noticed. The Gneissic basement

dates back to Archean Era (2500-3500 mya). A large granitic intrusion in south

central part of city extends from Golf Course to Vasantpur. Migmatitic intrusions



are seen near Kanakpura Road. These basic intrusions constitute hard massive rocks

such as Dolerite, Gabbro, Norite and Pyroxenite.

5.2.2 Seismic vulnerability

With regard to seismic vulnerability, the Project site is located in Bengaluru, Capital

City of Karnataka State. State of Karnataka comes under zone II (Low Risk) as per

Indian Standard IS 1893 (Part I-2002). Recent earthquakes that occurred close to

Bangalore were in the range of 2 to 5.5 in richter scale, on January 29, 2001,

earthquake magnitude of 4.3 in Richter scale hit in the Mandya area, with its epi

centre about 35km south of Bangalore.

5.2.3 Ground Water Conditions

An important aspect to be noted is static ground water was not noticed within

explored depth in any of the boreholes. Fluctuations in groundwater levels and

seepage flows can also occur due to seasonal variations in the amount of rainfall,

runoff, altered natural drainage paths, and other factors not evident at the time

when the exploration points were advanced. The d e s i g n e r a n d c o n t r a c t o r

executing the constructions should be aware of this possibility while designing

and executing the project. During executions, in case ground

water/runoff/seepage water is noticed, same shall be drained away, collected at a

peripheral location and disposed away from construction limits.

5.2.4 Building Condition

Two buildings are present in the site one is Office building along with a weigh

bridge and another one is Labour rooms. Building areas appear to be in good

condition. There is a workshop area where the unwinding, straightening and

cutting of steel coil wire rods takes place.

None of the suspected areas of the office building & surrounding area seemed to

have been contaminated. There were no spills, sharp objects, burn outs or damages



on floor or interior encountered at the site visit and finally the D.G room also looked

clean without any spills on the floor.

The soil is Silty Sandy/Sandy Silt, which is impervious in nature, proves that there is

no contamination to the soil. Hence, we can justify that there is very limited

contamination. However, in critical locations, floor concreting was done to ensure

that there will not be any contamination to the surrounding ecology and

environment.

5.2.5 General Housekeeping

Only loading and unloading operations were carried out in the site area. Unwinding,

straightening and cutting of coil wire rods were done inside the workshop area.

No major accidental releases of polluting materials, internally or externally, were

reported and none were observed during the site inspection.

5.2.6 Geology and Groundwater

The description of the local geology is based on profile of the borehole used for

extraction of the water and the same water is used for drinking as well as other

purposes. Two bore wells exist in the proposed site and both are in working

condition.

Given the limited data, the assessments of the sensitivity of the site can only be

approximate. The geological conditions of the site does not show any migration of

any contaminants along the subsurface water flow, however main water, bore well

samples are collected for analysis. Therefore the sensitivity of the site at this moment

can be assessed as low.

5.2.7 Surface Water

There are no surface water sources within the project site. There is no water body

such as river, pond within the vicinity of the project.



5.2.8 Soil Quality

Through soil investigations it is revealed that the soil is Sandy Silt type. The

laboratory investigations also reveal that there is no major soil contamination at site.

5.2.9 Water Resources and Consumption

The company uses water from existing bore well. In addition, the company used the

same for drinking water supply.

Water supply network has two connection points to building network– one close to

the office building and second close to labour rooms.

Water is generally used as potable water for company staff, for cleaning and for

sanitary needs.

There are no specific requirements for make-up water consumption in for purpose.

5.2.10 Storm Water Drainage

Storm water from the site is collected by storm water system composed of

pipes and surface flow along asphalted internal roads and directed to the

sedimentation pit. The main source of the storm water contamination is transport

equipment t used for bulk materials income and packed goods outcome. Trucks

are not washed at the site.

5.2.11 Raw Material Storage and Handling

Main raw material is Steel wire rod coils, TMT bars, automobile shafts etc,. The raw

materials were transported from Vizag Steels and stored in the site for further

distribution. Transport of materials and products is through trucks.

5.2.12 Greenhouse Gas Management

The company did not generate CO2 by burning fuel, rather the only emission is from

the trucks due to their movement. No specific management system was applied t o

monitor green house gases emissions.



5.2.13 Solid & Hazardous Waste Management and Disposal

No hazardous chemicals are reported to be used on site. Thus, the risk of significant

environmental impact of these materials is negligible.

5.2.14 Land Contamination

There is limited risk of substantial soil and groundwater contamination at the site as

the operations involved at the site do not show any significant volumes of hazardous

materials.

The risk of historic contaminations is also limited, which did not indicate any

contamination or potential pollution.

5.2.15 Health &Safety Management organization

The company had dedicated occupational health and safety manager responsible for

operational H&S issues. The scope of responsibilities include provision of initial and

periodic H&S training, supervision of initial and periodic health examinations,

contracting monitoring of occupational exposure levels and preparation of H&S

improvement programs.

5.2.16 Accidents

5.2.17 Improvement program

The main points of the plan include maintenance of equipment and

modernization of the production, compensations for heavy and hazardous work

conditions, operators working inside the buildings

5.2.18 Access to first aid

During site investigations, we were informed that there were first aid kits and doctor

on call to attend the health related issues within the factory premises.



5.2.19 Risk Assessment

In line the company developed the risk assessment for all the workplaces.

It is our opinion that the worker exposure to hazardous working conditions (like

dust, noise and vibration, chemicals, etc.) is limited due to non availability of the

evidence and no major improvements are required. The actions planned by the

Company and their improvement program should be sufficient to achieve full

compliance.

5.2.20 Medical tests and occupational diseases

No occupational diseases were reported. It is general opinion that there is no risk

that such occupational diseases appear in the future, no cases of claims, law suits

were reported.

6.0 Monitoring and Analysis

7.2 Anticipated Environmental Impacts and Mitigation Measures

Construction o f the proposed project is purely residential and will not have any

impacts on the environmental conditions of the site and surroundings.

7.2.1 During Construction Phase

The impacts during the construction phase of the proposed project on the

environment are basically transient in nature and are expected to reduce gradually

on completion of the construction activities.



7.2.1.1 Air Quality

During construction period, there is likelihood of generation of dust emissions. This

can be attributed by vehicular movements and other construction activities. Also

there will be emission of fugitive dust from the construction activities. The following

measures will be taken to reduce the impact on air quality.

Transport vehicles will be properly maintained.

Periodic water spraying

Any vehicle not meeting the vehicle pollution standards will not be allowed

within the construction activity.

Vehicles will be covered using tarpaulins to avoid spills and dust

emissions.

7.2.1.2 Noise Level

The noise levels during the construction phase will be well within the

acceptable limits. Noise will be produced due to movement of vehicles and allied

construction activities. The following measures will be taken to reduce the noise

impact.

All equipments will be operated as per the manufacturer manual to generate

minimum noise level and not to exceed the limits.

High noise generation equipment, if used will be operated during the day

time only and completely restricted during night hours and this eliminates

any possible discomfort to the nearby residents.

Ear muffs will be provided to workers.

7.2.1.3 Water Quality

There will be no labor quarters/colony on site. Suitable toilet facilities shall be

arranged at site for the convenience of the laborers. There is no likely hood of

ground water contamination, as no waste will be discharged to ground water. The

following measures will be taken to reduce the impact on water quality.



A temporary septic tank-soak pit shall be constructed for treatment and

disposal of wastewater.

The construction waste will be disposed off on land in a proper manner.

Construction equipment requiring minimum water for cooling and operation

for optimum effectiveness shall be chosen.

7.2.1.4 Solid / Hazardous Waste Disposal

Solid wastes generated during construction phase include domestic waste and

construction waste. The hazardous waste materials used during construction phase

will be spent oil from DG sets. The following measures will be taken for proper

disposal.

Solid wastes will be disposed off through Municipal Authorities.

Hazardous wastes like spent oil and paints will be stored in separate

enclosures and given to authorized recyclers.

7.2.2 During Operation Phase

The proposed project does not generate water or noise pollution to any significant

degree to impact the environment and cause any adverse effect. There is no highly

significant air, solid waste or hazardous waste emission from the project, which will

cause damage to the environment. The details are given below.

7.2.2.1 Air Quality

Major pollutants envisaged from the proposed project will be from DG sets and

vehicles movement. The major pollutants will be oxides of Nitrogen, particulates

and sulphur dioxide. The following measures will be taken to reduce the impact on

air quality.

Sufficient stack height will be provided as per KSPCB norms.

Green belt development with tall growing trees.

Periodic Ambient Air Quality Monitoring



7.2.2.2 Noise Quality

The major source of noise is DG sets. Adequate care has been taken while procuring

noise generating equipment & machinery to ensure that vendors have incorporated

adequate measures to minimize noise & vibrations. The following measures will be

taken to reduce the impact of noise.

DG sets will be provided with acoustic enclosures.

Noise attenuating green belt shall be developed for effective reduction in

noise.

Ambient noise levels will be periodically monitored to determine compliance

with the norms.

7.2.2.3 Water Quality

The water requirement for the project will be met from BWSSB & existing Bore wells.

The domestic wastewater generated from the proposed project will be treated in

proposed STP. The treated water will be reused for green belt development &

flushing, thus making it a Zero discharge project. Also, the following measures will

be taken to minimize the usage of water.

Rainwater harvesting for optimum utilization of rainwater and also to

recharge the ground water will be adopted.

Use of low flow fixtures and appliances for reduced water consumption.

Recycle and reuse of treated water from STP

7.2.2.4 Solid Waste Management

The Solid waste generated from the project is domestic in nature consists of paper,

cardboard, plastics, kitchen wastes and other general refuse by routine activities.

Organic waste will be disposed by proposed Organic waste converter and

inorganic waste will be further segregated and disposed to authorized recyclers.



8.0 Conclusions

The proposed Construction Project will not have any environmental impact due to

past industrial activity. The existing activity in the site does not pose any threat to

environmental parameters both long term and short term rather by shifting this

activity the traffic congestion problem in the area will be greatly solved. As the soil

and water analysis indicates absolutely no impact from the past activity and also the

activity of the future will not produce any impact which would affect air, soil or the

water environment. Hence the site could have positive potential for the future

activity.

"BOD5 Loading = 350 mg/lit

"Total BOD5 load = 340 x 1000 x 350kg/day

1000000 "Total BOD5 load =119 kg/day

BOD5 load in Kg/day in the aeration tank = 119 Kg

Oxygen required in Kg/day = 238 kg/day

(2 kgs of Oxygen is required for every Kg of BOD5 to be removed)

% of Oxygen in air = 0.21

Density of air = 1.2

Air Volume required per day = 944.4 m3 of 02 / day

No. of hours of oxygenation = 7.0

= 134.9 m3 / hr

Diffuser Transfer efficiency = 134.9/0.27 (27% for 4.5m submergence)

= 500 m3 / hr

Hence, Air volume required in Aeration tank = 500 x 30% extra

CONCLUSIONS

The STP would be able to treat the sewage to the standards prescribed by the KSPCB with

treated BOD levels less than 10 mg/lit. The treated water is safe to come in contact as the

chlorination is done to kill the bacteria disinfection. The treated water will be consumed in

irrigation, flushing toilets as well as washing pavements and driveways.



ANNEXURE - 2

STORM WATER COLLECTION & DISPOSAL SYSTEM

1.0 SCHEME

Storm water disposal system – From the Terrace area:

Rainwater vertical pipes from the terrace areas are taken into the shafts provided for

the purpose. These pipes are then dropped down to the ground floor level and get

terminated at the ceiling level of the ground floor wherein they are connected to

main headers of required higher sizes running suspended at ceiling level with the

help of brackets to support them. These rainwater pipes are then dropped down to

the ground level to connect to the catch basins and Hume pipe network, and finally

collected in the storm water collection sump. This water is proposed to be treated by

providing a filtration unit and then re-used for the domestic purposes.

Storm water disposal system – From the Podium Area:

From the podium area the storm water is effectively drained out by providing a

number of rain water pipes provided with grating on top. These rain water pipes are

in turn connected to the rain water pipes of higher diameters which are ceiling

suspended at the ground floor. These pipes are run in slope and supported by

brackets till they reach the peripheral storm water drain provided along the

periphery of Building.

2.0 Storm water disposal system:

a) From the basement area:

For draining out rain water/ car wash water collected in the basement floor, it

proposed to construct a storm water collection tank of suitable capacity at the

basement level. Numbers of storm water drain channels are provided in the

driveway through which the water in the basement area travels before finally getting

stored in the multiple number of storm water collection sumps provided. Thus

collected rainwater is pumped out/ discharged in to the nearest storm water drain /



pit constantly by a set of rainwater pumps operated automatically depending upon

the level in the tank.

b) From the Ramp area:

The water from the ramp areas is made to collect in the cattle drains provided with

CI/MS Grating on top. The water then reaches the storm water collection sumps

from where it is pumped to the external storm water drain.

c) From the Set back area:

The water from setback area is proposed to be drained off by provision of the main

storm water drains running along the periphery of the building. These drains are

covered on top with precast RCC Cover. The storm water run-off from the setback

area, ramp area and the basement area is proposed to be recharged by providing the

rainwater recharge pits provided.

STROM WATER RUNOFF CALCULATIONS:

Run-off co-efficient for various types of surfaces

Open grounds, unpaved street - 0.10-0.30

Parks, Lawns, Gardens - 0.10-0.25

Macadam roads, Pavements - 0.85-0.90

Asphalt pavements - 0.85-0.90

Water tight roof surface - 0.90-0.95

INTENSITY OF RAINFALL CONSIDERED IN BANGALORE: 100 mm/hr

Hence, The Total Quantity of Rainfall is given by:

Q = (C x I x A) / 360

Q= Quantity of rainwater run-off (m3/sec)

C = Run-off co-efficient

I = Rain fall intensity (mm/hr)

A = Area (hectares)

Land area = 21448 Sqm

Terrace area = 4890.00 Sqm

Green area = 7380.13 Sqm



Other Podium / Hardscape /

Driveways

= 12,886.3 Sqm

1) Roof Top Rain water Harvesting / Storage System

As per BBMP guidelines, Rain water storage tank of minimum 20 litres per day has

been considered.

Terrace area in Sqm = 4890.00 Sqm

= Terrace area in Sqm x 20 litres

= 97800 litres = 98 Cum

Approximately, Rain water Storage tank capacity considered is = 98 Cum

2) Rain water Recharging System

As per BBMP guidelines, a minimum capacity of 10 litres per Sqm of open space area has

to be provided.

Open Area in Sqm (Green + podium + hardscape + = 17,482.00 Sqm

driveway area)

Therefore,

Volume of rain water available for recharging is = Open area (Sqm) x 10 ltrs

= 174820 ltrs

= 174.82 Cum

Recharge Pit Calculation

It is assumed that Infiltration rate = 10 cm/s = 0.1 m/hr

Area of bottom surface of recharge pit = 1.13112 Sqm

Area of wetted perimeter of Recharge Pit = 11.3112 Sqm

( 3m depth considered)

Total area per Recharge pit = 12.44232 Sqm

Total water permeability / pit/hour = 1.244232 cum/hr

Total number of recharge pits required = 148 nos

Total number of recharge pits provided = 27 nos

Amount of water percolating through the recharge pits = 34 Cum

Therefore, Rain water storage

tank capacity in cum



Excess water after recharging through recharge pits = 150 cum

It is considered that :

Total depth of the chamber = 3 m BGL.

Total depth of the filter material in the chamber = 1.5 m

Voids in the combination of filter material = 50 %

Depth of Effective open space in the chamber = 1.5 m

Area of Recharge chamber

Surface area of well = Total run off from site/ Effective depth of well

= 67 Sqm

Adding 10 % for control unit, Total area required is = 73 Sqm

Requirement of Gravity Head Recharge well

The geohydrological situation of the ground water regime in the area is such that a

gravity head recharge well of 150 mm dia and strainer length of 30 m will have a

recharge efficiency of more than 50 m3/day.

So the number of recharge well requirement = Total volume available / Recharge

= 2 Nos.

Hence the area of each Recharge wells is = Total Surface area/ Number

=12.03 Sqm

Number of recharge wells provided = 6 Nos

Amount of Recharge water recharging through recharge wells is = 162 cum

Excess water finds its way to existing nala = -11.8 cum

3.0 Rain Harvest Pit:

Normally, the rain harvesting pits of suitable size is proposed to be constructed near

wells. The rain harvest pit consists of 2m dia borehole for depth as per site condition.

Boreholes are made with casing pipes in position, and then filled up with 20mm dia

riverside pebble/jelly stone and then casing pipe is removed. The pit outer wall is

constructed in brick masonry on PCC bed of 1:4:8 ratios. The first layer for 18” thick

is filled with pebble of size 1” – 3”. The second layer for 150mm thick is filled with

coarse sand. The third layer for 300mm thick is filled with 20mm dia jelly stones. The



fourth layer for 750mm thick is filled with 40mm dia jelly stones. The fifth layer for

1100mm thick in filled with boulders of suitable size. Finally the top of rain harvest

pit is covered with 600mm RCC precast slab with perforation of (min) 50 mm dia in

strip of size 2’0 wide, to allow entry of surface / ground level rainwater.

3. The hourly variation observed in Direction-1(Towards Hoodi Circle) nearest main road

(i.e., Hoodi main road) to the site varied in the range of 315-2118 VPH (Vehicles per Hour)

and in Direction-2 (Towards ITPL) varied in the range of 277-2651. In terms of PCU in

Direction-1 it varied from 353 - 2035 PCPH (Passenger Car Unit per Hour) and in Direction-

2 it varied from 355 - 2952 nos. PCPH (Passenger Car Unit per Hour). Peak traffic flows was

observed during 7.00 am – 10.00am in the morning and 05.00pm to 07.00pm in evening both

in Direction-1 & Direction-2.

1.3.4 Traffic Composition

Composition of traffic as observed in the main connecting road to the proposed project site of

M/s. Godrej Housing Projects LLP is shown in Figure 4 & 5. It is seen that the share of

Car/Jeep is the highest being 43 % in direction-1 and 37 % in direction-2.

From the figure 4 & 5 it is seen that 2-Wheeler constitute 39%, 3-Wheelers constitute 5%,

Light Commercial Vehicle constitute 5%, Bus constitute 3% & Heavy Commercial Vehicle

constitute 5% in direction-1 and 2- wheeler constitute 37%, 3-Wheelers constitute 8%, Light

Commercial Vehicle constitute 3%, Bus constitute 6% & Heavy Commercial Vehicle

constitute 6% respectively.

1.4 Likely Traffic in the Post Development Scenario

Considering the provision given for a total car parking of 1945 nos. and the conservative peak

hour trip is assumed to be 10% of daily trips, the proposed property development is likely to

contribute about 200 PCU’s during peak hour.

The existing traffic scenario & level of service was found is C means good and total traffic

generated from the proposed project, the level of service will be “D” means Fair.

1.8 Factors Considered in Planning

The important factors considered in planning of the entrance road to the proposed project sit

from the main road are.

It is planned such a way that it blends well with the existing road.

Layout will be harmonised so that it is aesthetically pleasing.

1.9 Proposed Improvements

Improvement to the entrance road geometry.

Quick traffic dispersal

Entrance Bell gates

Controlled /regulated traffic flow, ensuring conflict free entry/exit of vehicles to the

property.

Appropriate street furniture comprising of lane markings, pedestrian facilities etc.

1.10 Conclusions

The proposed improvements plans ensure smooth traffic flow, adequate pedestrian facilities

and highest pedestrian safety in addition to contributing to an aesthetically pleasing location.

The proposed site and the adjoining road have a potential of becoming a landmark in the city

blending harmoniously with the surroundings and city’s heritage. The proposed project will

slightly affect the traffic flow as towards Marathalli & it will be eased once the BDA

proposed flyover at the Doddanekkundi junction & proposed Doddanekkundi Metro Phase II

station are completed and starts operating.
