ENVIRONMENTAL IMPACT ASSESSMENT REPORT 1

CHAPTER: 1

INTRODUCTION

Preamble:

Ministry of Environment & Forests (MoEF), Government of India, in 1994 made

preparation of REIA/EIA & Environmental Management Plan (EMP) mandatory for 30

different activities for categories under Schedule - I of EIA Notification. Further on

7.7.2004, EIA notification was amended to include Construction Projects in the ambit

of Environmental Clearance process this notification was based on the criteria of the

total contributing population, Investment made and wastewater discharge from

projects seeking Environmental Clearance. Further, on 14th September 2006 the

Ministry of Environment and Forests amended the existing Notification & Rules making

built up area as the criteria for Environmental Clearance thus any building and

construction projects with a built-up area >20,000 sq m and <1,50,000 sq m comes

under Schedule 8 (a) of the notification necessitating Environmental Clearance from

the regulatory authority. Preparation of Impact Assessment Report is necessary for

Township and Area Development Project (Schedule 8 (b)) covering an area >50 ha and

or built up area >1,50,000 sq m.

1.1 PURPOSE OF THE REPORT:

The purpose of Environmental Impact Assessment (EIA) is to assist in the decision

making process and to ensure that the project under consideration are environmentally

sound and sustainable. EIA identifies the ways of improving project environmentally by

preventing, minimizing, mitigating or compensating the adverse impacts. Urban

development projects including housing and office complexes do have the potential in

altering environmental resources of any urban area. They cause stress on local

environmental assets of the urban area and could become the potential source for

limiting the growth of the city. Unplanned construction and occupancy of such projects

usually result in impacts on various facets of environment.

Keeping above issues under consideration, an Environmental Impact Assessment (EIA)

study is conducted which incorporates into development and planning process, a plan

for environmental protection and conservation. The procedure identifies the possible

positive and negative impacts on the environment likely to emanate as a result of

construction and occupancy of a project. The EIA thus, provides for a plan which, upon

“Green Fields”


implementation, will reduce or offset the negative impacts of a project resulting in a

minimum level of environmental degradation. This minimization may be the result of

implementation of project modifications or environmental protection measures which

simply reduces the severity or number or magnitude of negative impacts. The plan may

also result in utilization of positive impacts for enhancement measures which offset

negative impacts. To measure the level of plan implementation and the degree of

effectiveness of the above environmental protection provisions, the EIA provides a

monitoring program. This program is so designed that it identifies the parameters of

uncertainty and measures the related impacts. It is necessary that there is close

integration of EIA with various aspects of a project including financial and engineering

aspects which ensures environmental consideration are given due weight in project

selection, siting, design and operation. Analysis of past experiences indicates that it is

necessary to examine a number of problem areas in-order to ensure that environmental

concerns can be effectively integrated in the development process. Similar approach

has been adopted while conducting the EIA study for the proposed project.

1.2 SCOPE OF EIA:

The scope of Environmental Impact Assessment study includes a detailed study of the

existing environmental status within the study area of 5 km radius from the proposed

site for significant environmental components/parameters viz. air, water, land,

biological, socio-economic and cultural environment. This serves as a prevalent

environmental component of the area around the project site depicting the baseline

characteristics of the environment before the actual establishment of the project. This

broadly covers.

Assessment of environmental features of the project.

Establishment of present status of air, noise, water, terrestrial, biological &

socio-economic components of the environment.

Identification and quantification of probable or likely impacts due to the

implementation of the project on the prevailing environmental settings during

the Occupancy phase.

Evaluation of proposed pollution control programs adopted by the project to

combat the possible pollution of air, water, noise, terrestrial environment etc.,

Compilation & assimilation of collected, generated data during the course of EIA

studies.

“Green Fields”


Delineation of Environmental Management Plan (EMP) outlining measures to be

adopted for mitigation of adverse impacts, enumerating post project

environmental quality monitoring to be followed by the project proponent.

1.3 METHODOLOGY OF EIA:

Any human establishment invariably has certain impacts on the surrounding

environment, which may be either beneficial or adverse. The nature and the magnitude

of the impact is a relative concept based on the nature & magnitude of the activity that

is intended to be carried out and also depends on the prevalent environmental setting

of the proposed area and its sensitivity to the changes that are likely to be brought

about due to the proposed activity.

Therefore, the net impact of any proposed activity could be accessed through a

exhaustive study of the environmental parameters within the study zone prior to the

implementation of any proposed project and presented in the form of ENVIRONMENTAL

IMPACT ASSESSMENT (EIA) report which serves as a basis for the establishment to

develop strategies to combat the pollution either at its source of generation or at the

end of the pipe and also to implement measures to reduce the pollution either

quantitatively or qualitatively by resorting to suitable technological up-gradations from

time to time.

The EIA studies can be broadly divided into three phases.

The first phase involves field studies to assess or identify the significant

environmental components, which serves as a baseline status within the study

zone.

The second phase involves the prediction of all the impacts comprehensively on

the existing baseline status of various environmental components due to the

proposed activity. The process evaluation is also carried out to assess the

consumption of liquid & solid fuel, quantification & characterization of effluents,

solid and hazardous wastes, as applicable.

The third phase includes evaluation of impacts on the environmental setting and

assessment of its effects and delineation of an Environmental Management Plan

to mitigate adverse impacts on the quality of surrounding environment.

1.4 ENVIRONMENTAL REGULATORY CONTEXT:

This section reviews the policies and the Environment legislations at the National and

State level to understand the legal requirements and implications on the proposed

project. All activities under the proposed project must be consistent with all applicable

laws, regulations, notifications, and standards. It is the responsibility of the project

Implementing Agency to ensure that project activities are consistent with the

regulatory/legal framework, whether National, State or Municipal/Local.

1.5 INDIAN ENVIRONMENTAL LEGISLATIONS:

The Constitution of India directs the State to endeavor to protect and improve the

environment and to safeguard the forest and wildlife of the country. Article 51(g) of

the constitution states that it shall be the duty of every citizen of India to protect and

improve the national environment including forests, lakes, rivers and wildlife and to

have compassion for living creatures. The language of the Directive principles of the

State Policy (Article 47) also contains a specific provision, which commits the state to

protect the environment. In addition to Constitutional provisions, India has established

a comprehensive set of laws for the management and protection of the environment.

The Acts, Notifications, Rules and Amendments applicable to any type of development

projects include the following:

The Environment (Protection) Act and Rules, 1986.

The Environmental Impact Assessment (EIA) Notification, 1994 and amendments

for Environmental Clearance.

“Green Fields”


Note: The Ministry of Environment and Forests (MoEF) has stipulated general discharge

standards for water effluents and general emission standards for air and noise

emissions. These standards limit the concentration and volumes of the effluents and

emissions released to the atmosphere. The respective State Pollution Control Boards

(SPCBs) could make these standards more stringent based on the environmental

sensitivity of a specific location.

The project proponents are required to take Consents (for both air and water) and No

Objection Certificates (NOCs) from the relevant SPCBs before initiating any activity.

In addition to the above, the Central Pollution Control board (CPCB) has also specified

National Ambient Air Quality and Noise Standards for residential, commercial, industrial

and sensitive zones for the country as a whole.

1.6 MAJOR PROVISIONS IN INDIAN ENVIRONMENTAL LEGISLATIONS:

The Environment (Protection) Act, 1986 including Rules, 1986:

This Act is an umbrella legislation that provides a single focus for the protection of the

environment. The potential scope of the Act is broad, with “environment” defined to

include water, air and land and the inter-relationships which exist among water, air,

land and human beings and other living creatures, plants, micro-organisms and

property. The Act has been enacted to provide for the protection and improvement of

environment by preparation of manuals, codes or guides relating to prevention, control

and abatement of environment pollution.

The Act provides powers to the Central Government to take necessary measures for the

purpose of protecting and improving the quality of the environment and prevention,

control and abatement of environmental pollution. It lays down standards for the

quality of the environment, emissions or discharges of environmental pollutants from

various sources. It provides restriction on discharge or emission of pollutants in excess

of the prescribed standards. Environmental Impact Assessment Notification, 1994 and

the various amendments pertaining to this notification form a part of the regulations

under this legislation.

Environmental Impact Assessment (EIA) Notification, 1994 and Amendments:

As per the EIA notification, 1994 and subsequent amendments, new or expansion or

modernization of any activity falling in the 32 categories of activities shall not be

undertaken in any part of India unless it has been accorded environmental clearance by

“Green Fields”


the Central Government in accordance with the procedures specified in the

notification.

Until January 1994, obtaining environmental clearance from the MoEF was only an

administrative requirement intended for mega projects undertaken by the government

or public sector undertakings.

Relevance to the construction projects:

Certain type of urban housing projects needs Environmental Clearance from the MoEF.

These include (Obtaining Clearance by Preparation of EIA Report) Township and Area

Development Project (Schedule 8 (b)) covering an area >50 ha and or built up area

>1,50,000 sq m. Project proponents should adhere to the conditions prescribed in the

clearance. In all their plant operations, the proponents need to meet the requirements

/ standards prescribed in the various Environmental Protection Rules and other

environmental regulations. Whenever a project is given environmental clearance, a set

of recommendations and conditions are stipulated by the Appraisal Committee that has

to be complied with by the proponent once the project is commissioned. Project

authorities are required to submit periodical compliance reports to the MoEF to enable

the Ministry to monitor the implementation of the recommendations and conditions of

environmental clearance. Cases of non-compliance of recommendations and conditions

of environmental clearance are brought to the notice of the concerned SPCB for action.

The Air (Prevention and Control of Pollution) Act, 1981:

This Act was enacted to implement measures devised for the effective prevention,

control or abatement of air pollution. The Act prohibits the construction and occupancy

of any specified activity without the consent of SPCBs. For the prevention and control

of air pollution, the State Government, in consultation with the SPCB has the powers

to set standards for emissions from automobiles, impose restrictions on use of certain

activities and prohibit emissions of air pollutants in excess of the standards laid down

by the SPCB. It can also make an application to the court for restraining persons from

causing air pollution. In addition, it also has the power of entry and inspection, power

to obtain information and power to take samples of air emissions and conduct the

appropriate follow up. The CPCB, as well as the SPCBs are eligible for contributions

from the Central as well as the State Government, respectively, to perform their

functions appropriately. The Act also allows for appropriate penalties and procedures

for non-compliance.

“Green Fields”


The Water (Prevention and Control of Pollution) Act, 1974, amended in 1988:

This Act has been enacted to implement measures devised for effective prevention and

control of water pollution. It empowers the State Pollution Control Board to prepare

manuals, codes or guides relating to treatment and disposal of sewage and trade

effluents and information dissemination for maintaining or restoring wholesomeness of

water.

The Water (Prevention and Control of Pollution) Cess Act, 1977:

This Act provides for levy and collection of Cess on water consumed by persons carrying

on certain activities and by the local authorities with a view to augment the resources

of CPCB and SPCBs for the prevention and control of water pollution, constituted under

the Water Act, 1974. It also covers specifications on affixing of meters, furnishing of

returns, assessment of Cess, interest payable for delay in payment of Cess and penalties

for non-payment of Cess within the specified time.

The Hazardous Wastes (Management and Handling) Rules, 1989 (as amended, May

2003):

The Act requires owners to identify their wastes for applicability under the hazardous

wastes amendment rules 2003 and manage them as per the prescribed guidelines. The

assessment criteria under the amended rules are based on process and concentration.

The Public Liability Insurance Act, 1991:

The Public Liability Insurance Act (PLI), 1991, imposes on the owner the liability to

provide immediate relief in respect of death or injury to any person or damage to any

property resulting from an accident while handling any of the notified hazardous

chemicals. This relief has to be provided on "no fault" basis. Owner handling hazardous

chemicals has to take an insurance policy of an amount equal to its "paid up capital" or

Noise Standards for Stationary DG sets

The prescribed noise standards for control of noise pollution from stationary Diesel

Generator (DG) sets are given subsequently.

(A) Noise standards for DG sets (15-500 kVA)

The total sound power level, LW, of a DG set should be less than, 94+10 log10 (KVA), dB

(A), at the manufacturing stage, where, KVA is the nominal power rating of a DG set.

This level should fall by 5 dB (A) every five years.

(B) Mandatory acoustic enclosure/acoustic treatment of room for stationary DG sets

(5 KVA and above)

Noise from the DG set should be controlled by providing an acoustic enclosure or by

treating the room acoustically.

The acoustic enclosure/acoustic treatment of the room should be designed for minimum

25 dB(A) insertion loss or for meeting the ambient noise standards, whichever is on the

higher side (if the actual ambient noise is on the higher side, it may not be possible to

check the performance of the acoustic enclosure/acoustic treatment. Under such

circumstances the performance may be checked for noise reduction up to actual

ambient noise level, preferably, in the night time). The measurement for Insertion Loss

may be done at different points at 0.5 m from the acoustic enclosure/room, and then

averaged.

The DG set should also be provided with proper exhaust muffler with Insertion Loss of

minimum 25 dB (A).

(C) Guidelines for the manufacturers/users of DG sets (5 KVA and above)

The manufacturer should offer to the user a standard acoustic enclosure of 25

dB(A) Insertion Loss and also a suitable exhaust muffler with Insertion Loss of 25

dB(A).

The user should make efforts to bring down the noise levels due to the DG set,

outside his premises, within the ambient noise requirements by proper siting and

control measures.

“Green Fields”


The manufacturer should furnish noise power levels of the un-licensed DG sets

as per standards prescribed.

The total sound power level of a DG set, at the user's end, shall be within 2 dB(A)

of the total sound power level of the DG set, at the manufacturing stage, as

prescribed.

Installation of a DG set must be strictly in compliance with the recommendation

of the DG set manufacturer.

A proper routine and preventive maintenance procedure for the DG set should

be set and followed in consultation with the DG set manufacturer which would

help prevent noise levels of the DG set from deteriorating with use.

1.8 ENVIRONMENTAL CLEARANCE REQUIREMENTS:

As per the policies and legal framework, for any new activity the following set of

Environmental Approvals are necessary from the State Pollution Control Board (SPCB):

Consent to Establish

Consent to Operate

Consent To Establish:

The provision of “Consent to Establish” under the Water and Air Acts have been made

obligatory after amendments to the Acts made in 1988 and 1987 respectively. Earlier,

SPCBs were issuing separate NOCs for only siting of an industry and for adequacy and

appropriateness of pollution control equipment and related measures. This requirement

has now been replaced by the “Consent to Establish” and even extended to projects on

housing and office complex. However, some SPCBs have not yet notified the amended

rules. In such cases, the proponent is still required to obtain a NOC from the SPCB and

not the “Consent to Establish”.

Consent to establish for discharge of effluents under the Water Act, 1974

All projects (operation, process or any treatment and disposal system) which are likely

to discharge sewage or trade effluents into a stream, sewer or on land, are required to

obtain ‘Consent to Establish for Discharge of Effluents’ under the Water Act, 1974

(amended in 1988). For obtaining this consent, an application is to be submitted to the

concerned SPCB in the prescribed form along with the prescribed application fee.

“Green Fields”


Consent to establish for emission under the Air Act, 1981:

All projects (operation or process) located in an Air Pollution Control Area (APCA)

declared so by the concerned SPCB, and likely to emit air pollutants in the atmosphere,

are required to obtain ‘Consent to Establish for Emissions’ under the Air Act, 1981

(amended in 1987). For obtaining this consent, an application is to be submitted to the

concerned SPCB, in the prescribed form and along with the prescribed application fee.

After obtaining the ‘Consent to Establish’ and ‘Environmental Clearance’, the project

proponents can begin work related to the setting up of the project. After this, a periodic

compliance report is to be submitted indicating effective implementation of the

recommendations and connotations.

Consent to Operate:

It is obligatory to obtain ‘Consent to Operate’ from the SPCB under the provisions of

Water (Prevention and Control of Pollution) Act, 1974 and Air (Prevention and Control

of Pollution) Act, 1981 prior to the operation (occupancy in case of residential

apartment) of particular projects. While issuing these consents, conditions relating to

emission and discharge limits as well as other conditions are stipulated.

Implementation of these conditions may also be monitored for their effective

implementation.

2.7.1 Water Distribution System:

The proposed water supply scheme to cater to the public and domestic water

requirement of the proposed project consists of sourcing potable water to a common

collection facility known as the Raw Water Sump. The Raw Water Sump will be

constructed in RCC. The water from the UG sump will be pumped to overhead tank.

The OHTs will be staged on terrace depending on the contour of its distribution

network.

2.7.2 Sewage Generation & Disposal System:

Wastes of different type such as spent water from bath rooms, water closets/pans,

house and street washings, semi liquid waste of human excreta, refuse of house and

street sweepings, crockery etc., are produced daily. If proper arrangement for

collection treatment and disposal of all the wastes produced are not made, unsanitary

conditions will develop and it will become impossible for public to live. Therefore, it is

most essential to collect, treat and dispose all the sanitary wastes produced. Generally,

it has been observed that about 75 - 80 % of the water supplied comes out as sewage.

Therefore, total quantity of wastewater generated from the proposed project is worked

out as below:

2.7.3 Treatment Methodology:

The Sequencing batch reactor (SBR) process is a sequential suspended growth (activated

sludge) process in which all major steps occur in the same tank in sequential order

(figure 1). There are two major classifications of SBRs: the intermittent flow (IF) or

“true batch reactor”, which employees all the steps in figure 1, and the continuous

flow (CF) system, which does not follow these steps.

Both have been used successfully worldwide installations. SBRs can be designed and

operated to enhance removal of nitrogen, phosphorus, and ammonia, in addition to

removing TSS and BOD. The intermittent flow SBR accepts influent only at specified

intervals and, in general, follows the five-step sequence. There are usually two IF units

in parallel. Because this system is closed to influent flow during the treatment cycle,

two units may be operated in parallel, with one unit open for intake while the other

runs through the remainder of the cycles. In the continuous inflow SBR, influent flows

continuously during all phases of the treatment cycle. To reduce short circuiting, a

partition is normally added to the tank to separate the turbulent aeration zone from

the quiescent area.

The outfall sewer main from the last manholes, will be let into a screening chamber by

gravity flow. Large solids particles shall be intercepted by a fine screen. The screen

shall be manually cleaned with suitable rake arrangement at periodic intervals.

The sewage after screening is collected in a equalization tank for smoothing out peak

flows. This sump is sized to accommodate peaks, as well as breakdown buffer. The

provision of air shall be kept in this tank to break the solids in suspension and

homogenize the sewage.

The homogenized effluent is then pumped into the SBR Reactor. The air shall be

provided through an air diffusion system to ensure equal distribution of air in the

reactor.

The overflow from the SBR reactor is passed through a settler, and collected in Clarified

Tank by gravity, from where it is pumped to a pressure sand filter, which is capable of

removing finely divided colloidal particles. An activated carbon filter will remove all

traces of color and odor, so that treated water shall be used for gardening.

Filter backwash and sludge filtrate, would be taken back into the collection sump.

Sludge generated in the settler will be de-watered in a sludge filter press and bagged

for removal. This sludge will be used as organic manure.

Treated water will be passed to softening system. After softening water will be used

for flushing, gardening and AC make up water requirement.

2.8 SITE CLEARANCE AND PROPOSED LANDSCAPING:

The project site was barren land without any vegetation. In the project 700 new trees

are proposed to be planted in the site. The landscape of project site has been planned

to provide a clean, healthy and beautiful green environment for the people. Within the

proposed project site 74% is open space, and in this about 33% of the total space has

been designated for landscape development and has been designed to achieve a blend

between modern building and various species of plants, shrubs, to create a clean,

healthy and aesthetic environment that provides a visual retreat and relaxation to the

occupants of these buildings. Most of the plant species proposed to be planted in the

project will have better environmental value in terms of helping soil texture building,

less maintenance, help bio diversity by producing nectars, fruits etc., which attract

birds and insects. The proposed Landscape area in the project is proposed with

combination of evergreen trees and ornamental flowering trees and palms.

2.9.1 Water Supply, Discharge, Treatment & Disposal Details:

The main issues of concern from the environmental point of view are the proper

treatment & disposal of domestic sewage, management of domestic garbage and

adequate measures for controlling the noise pollution from generators. A description of

the above mentioned aspects is detailed in the following sections.

2.9.2 Source of water Supply:

The water supply is from Mandur Gram Panchayath Sources.

2.9.3 Storm water management system:

In general the rainwater from terraces and other elevated open areas is proposed to be

collected through rainwater down-take pipes connected to catch basins. The rain water

from hard courts and landscaped area shall be collected by catch basins through a RCC

pipe network/open drains with gratings and connected to the storm water

manholes/channels in the project. The collected water from the catch basins will be

“Green Fields”


diverted to rain water harvesting pits. Provision is to be made for rain water harvesting

as required by the Codes.

2.10 RAIN WATER HARVESTING AND GROUNDWATER RECHARGING:

Rain is the first form of water in the hydrological cycle and hence it is considered as a

primary source of fresh water to sustain life on earth. Rivers, lakes (surface water) and

groundwater are all secondary sources of water. At present we depend solely on these

secondary sources of water for all our fresh water needs and in the process the primary

source of water i.e., rainwater is totally neglected. Therefore, the concept of

harvesting rainwater to find its optimum use finds relevance in today’s scenario.

Of all the secondary sources of water i.e., surface and subsurface water sources, there

has been extensive tapping or abstraction of groundwater over the years to cater to all

the human needs. This has resulted in drastic depletion of groundwater. In addition to

this, due to rapid industrialization and urbanization, several impervious structures have

come up thereby reducing the unpaved areas, which hitherto were helping the natural

recharge of groundwater. Therefore, the concept of rain water harvesting along with

groundwater recharging is gaining importance in today’s world.

2.10.1 VOLUME OF RAIN WATER HARVESTED:

The total quantity of water i.e., received in the form of rainfall over an area is called

the rain water endowment of that area, out of which the amount of water that can be

effectively harvested is called the rain water harvesting potential.

Rain Water harvesting potential = Intensity of Rainfall (m) x Roof Area x Impermeability

Factor.

The collection efficiency accounts for the fact that all the rain water falling over an

area cannot be effectively harvested due to losses on account of evaporation, spillage

or run off etc.,

According to the data available from the Indian Meteorological Department, the

Average annual rainfall around month of September = 194.80 mm

Assuming that about 90 % Rainfall can be effectively harvested.

Number of Rainy Days = 9.3

Therefore the I.R = 194.80/9.3= 20.94 mm/day or 0.02094 m/day

or 0.021 m/day

The ground coverage area of the proposed project is about 18,814 sq m

“Green Fields”


For rain water harvesting consider 75 % of this total area is 14,111 sq m

Quantity of Rain Water that can be harvested from the building is as follows.

Rain water (Q) from Roof top = 0.021 x 14,111 x 0.9

= 266.7 cum/day or say 267 cum/day

Storm water disposal is divided into 2 Groups:

Terrace Storm water disposal: The entire rainwater from the terrace would be

disposed through suitable rain water pipes and collecting in the dedicated rain

water collection sump, which is proposed at site level. This water will be utilized

for domestic purpose (as detailed in VOLUME OF RAIN WATER HARVESTED).

Site (Paved and landscape area) Storm water disposal: The entire storm water

from the site would be disposed off through suitable RCC Box drainage system to

the rainwater recharge pits and the excess is diverted to external storm water

drainage.

The amount of storm water that the paved area will produce can be determined by

considering the impermeability factor to be 0.9.

Q = 0.021 x 30,138 sq m x 0.9


The amount of storm water that the landscaped area will produce can be determined

by considering the impermeability factor to be 0.3

Q = 0.021 x 24,111 sq m x 0.3


The Total amount of storm water = paved area + landscaped area

= 570 + 152 cum/day

= 722 cum/day

The Proponents shall also Provide Recharging Pits along the inner periphery of the

boundary wall with recharging pit of size 1.2 m dia x 2.5 m deep spaced at 20 m center

to center. These recharging pits are filled with graded media comprising of Boulder at

bottom and with coarse aggregates to facilitate percolation of harvested rain water to

Recharge Ground Water table. The Recharge Pits are interconnected in such a way that

“Green Fields”


the rain led to the first recharge pit is also led to the next pit. The excess rain water

shall be drained off to the storm water drain.

2.11 SOLID WASTE GENERATION & ITS MANAGEMENT:

2.11.1 Domestic solid waste management:

The wastes that are generated from the day to day activities which are in solid form

are categorized as solid wastes. Solid Wastes include dry refuse of house and street

sweepings, crockery, Kitchen Wastes, electronic wastes. Collection, disposal and

management of Solid Wastes are very important to avoid the nuisance and unhygienic

conditions. The quantity of solid waste generated from project is calculated as under

table 2.4.

Per capita generation of refuse from residential establishments: 0.3 to 0.6

kg/capita/day according to the Manual on Municipal Solid Waste Management (first

edition) – Pg. 48, 3.3.6.2.

The solid Wastes generated will be segregated at its point of generation and collected

separately in different color coded Synthetic Bins depending upon the basis of its Bio

Degradability at a common designated point. The collection and disposal of the solid

wastes from the Project is done in such a way that it is scientifically disposed without

causing eyesore or any adverse effects to the surrounding environment. Organic solid

waste from the project will be treated in an organic converter and is used as manure

for Landscape or used as fuel. The inorganic solid waste will be sent for recycling.

DESIGN PHILOSOPHY:

A. CONCRETE STRUCTURES

The structure proposed is of cast in-situ concrete construction with columns suitably

placed. The core walls around lifts, stairs and shear walls are of cast in-situ concrete

to resist lateral forces.

The structural design of the project is based on Indian Standard Codes and is analyzed

for dead, live, wind and seismic load conditions taking into consideration relevant load

combinations recommended by the codes.

The vertical loads including the dead and superimposed loads and the lateral loads due

to wind and seismic forces are transferred to the soil through proposed reinforced

concrete core walls/shear walls, columns and footings. Footings are sized with

consideration to the safe bearing capacity of soil at the level of transfer of load

recommended by specialist soil investigation consultants. Geo technical Investigation

has been carried out to assess the soil stability and safe bearing capacity for designing

the proposed structure in the project.

The type of footings proposed is either individual, combined or raft depending on the

soil investigation report at specific locations as the soil strata varies considerably over

the extent of proposed plot.

Following are the design considerations for the liquid retaining structures.

“Green Fields”

1.2 ESTABLISHMENT OF BASELINE:

3.2.1 Meteorological Environment:

Assessment of the micro and macro meteorology is important from the standpoint of

understanding the nature and extent of air pollution in the study area. Climate has an

important role in the build-up of pollution levels. The climatic condition of the area may

be classified as moderately or seasonally dry, tropical or temperate savanna climate with

four seasons in a year. Winter is critical for air pollution build-up because of frequent

calm conditions with temperature inversions resulting in poor atmospheric mixing,

natural ventilation and high emission loads.

The classification of months according to the seasons is given in the following table

NOISE & SOIL QUALITY:

EQUIPMENTS USED FOR NOISE & SOIL MONITORING:

Noise levels were measured using integrated sound level meter & soil quality using pH

meter, Conductivity meter, Turbidity Meter, Flame Photometer, Spectro photometer,

Mercury Analyzer, Oven, Electronic Balance.

SAMPLING AND ANALYTICAL TECHNIQUES:

3.2.2.2 AIR ENVIRONMENT:

A methodologically designed Air Quality Surveillance Program (AQSP) should form the

basis for the impact assessment on air environment, which ultimately helps in

formulating a sound EMP. The basic consideration for designing such program includes.

1. Representative selection of sampling locations primarily guided by the

topography and micrometeorology of the region,

2. Adequate sampling frequency,

3. Inclusion of all the major pollution parameters.

All these aspects were given due consideration for devising an optimal scheme for “Air

Quality” surveillance program for Environmental Impact Assessment [EIA] around the

proposed project site.

3.2.2.2(a) RECONNAISSANCE SURVEY The prime objective of this ambient air quality survey within the study area for the

project was to establish the existing Ambient Air Quality levels. Major sources of air

pollution were identified as vehicular movement by the local populace and movement

of tucks, lorries and other vehicles. There are no other major air pollution sources

within the study area.

The fluctuations in ambient air quality within the study area of the proposed project

are expected to be governed by the overall regional emissions and micro-meteorology

of the study area.

“Green Fields”


3.2.2.2(b) AIR QUALITY:

The baseline air quality was established by monitoring major air pollutants like

Suspended Particulate Matter (SPM), Oxides of Sulfur (SO2) & Nitrogen (NOx), Carbon-

Monoxide (CO) etc., at various locations near the project site. High volume samplers

were used for ambient air sampling. Suspended Particulate Matter (SPM) i.e. PM2.5&

PM10, sulfur dioxide (SO2), oxides of nitrogen (NOx), NH3, Pb,O3 were determined.

Samples were collected continuously from all the stations for 24 hours. Samples thus

collected were analyzed for various pollutants as indicated in the section above.

Baseline data for ambient air quality was collected during the months of March to May

2016. The sampling stations along with their distance and direction from the project

site, ambient air quality monitoring stations, wind rose diagram showing the direction

of the blowing wind during the analysis period, ambient air quality analysis data &

National Ambient Air Quality Standards specified by MoEF are detailed subsequently.

To study the existing ambient air quality, monitoring was done by Bangalore Test House,

Bangalore, NABL Accredited lab for the project site & other locations.

The sampling stations along with their distance and direction from the project site is

detailed in Table 3.3, Ambient Air Quality monitoring stations are shown in Fig 3.3,

ambient air quality analysis data is shown in Table 3.4, National Ambient Air Quality

OBSERVATIONS:

It has been observed that the maximum concentration of SPM, SO2, NOx, Pb & O3 at all

the locations are within the limits specified by MoEF (as per the notification dated 16th

November 2009 for Industrial, Residential & Rural areas). Marginally high values at KHB

Colony, Hosakote are due to the frequent movement of vehicles on the main road close

to the sampling location.

3.2.3 NOISE ENVIRONMENT: Any construction project necessitates movement of construction materials during the

construction phase and movement of residents during the occupancy phase which will

“Green Fields”


result in a moderate increase in the traffic, which would not result in any drastic change

in either the existing traffic pattern or noise levels of the area.

Background noise levels were measured in 5 locations (Table 3.6), monitoring locations

depicted in map (Fig 3.3) in human settlements within the study area. A sound level

meter was used for measuring the noise level at one-hour interval continuously for 24

hrs at 1.5 m above ground level, about 3 m from walls, buildings or other sound

reflecting sources.

The measurements were carried out in such a way that the monitoring locations were

1 m away from the sources and 1 m away from the edge of the roads. The lowest and

the highest noise levels are presented in Table 3.7 and limits as per Environmental

Protection Rules, 1986 for the project are presented in Table 3.8as under.

OBSERVATIONS: The baseline noise levels have been monitored at different locations as indicated in the table above. Marginally high noise levels at Project are due to the construction activities, movement of vehicles and operation of machineries.

3.2.4 HYDROLOGY AND HYDROGEOLOGY

Geographically the site is located at Latitude: 13°4.288' N and Longitude- 77°45.138' E with 898 m above MSL. Water bodies around the site are Lagumenahalli lake (at about 70 m on North East Direction), Hosakote lake (at about 1.3 Km on East Direction) and Katamnallur lake (at about 1.75 Km on South Direction)The ground water in the area occurs under water table conditions in the weathering mantle of the granite gneisses and in the joints, cracks and crevices of the basement rock. Ground water is derived mainly from precipitates. Smaller amounts are derived from infiltration of water from the tanks and the water used for irrigation. Most of the rainwater is lost through evaporation and run off, only a small percentage reaches the groundwater reservoir.

3.2.5 WATER ENVIRONMENT: 3.2.5.1 RECONNAISSANCE SURVEY The impact has been assessed on randomly selected surface and ground water sources

Accidents, Project Design, Project Construction, Regular Operations, Final

Decommissioning or Rehabilitation of Completed Project

4.1.1 Environmental impacts due to project location, possible accidents, project

design

PROJECT LOCATION:

Major environmental impacts due to project location is not anticipated because

• The proposed project is Expansion of Residential Apartment project. • No national park and environmentally sensitive areas area located around the

project site.

POSSIBLE ACCIDENTS:

The proposed project is Expansion of Residential Apartment project. All precautionary

measures are taken in construction activities of the project and optimum utilization of

the existing infrastructural facilities will be made. Therefore environmental impacts

due to possible accidents are not anticipated.

PROJECT DESIGN

The project is designed with utmost consideration to the environment. a) Green-belt/landscape development is earmarked in the project. b) Indigenous / native trees species of different species are proposed to be planted. c) Environmental Infrastructure facilities like Sewage Treatment Plant for treating

the wastewater from the project. Organic Waste Converter for treating the Organic Waste, the product will be used as manure.

d) Rain water harvesting and Ground water recharging is proposed in the project to enhance ground water potential in the area.

e) Use of alternative source of energy like solar lighting, solar hot water generation

will assist in reducing load on conventional energy sources.

“Green Fields”


4.2 MEASURES FOR MINIMIZING AND / OR OFFSETTING ADVERSE IMPACTS

IDENTIFIED:

The Environmental Management Plan (EMP) is aimed at mitigating the possible adverse

impact of a project and ensuring the existing environmental quality. The EMP converse

all aspects of planning, construction and occupancy of the project relevant to

environment. It is essential to implement the EMP right from the planning stage

continuing throughout the construction and occupancy stage. Therefore the main

purpose of the Environmental Management Plan (EMP) is to identify the project specific

activities that would have to be considered for the significant adverse impacts and the

mitigation measures required.

The construction phase impacts are mostly short term, restricted to the plot area and

not envisaged on the larger scale. In the occupancy 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 following mitigation measures

are recommended in order to synchronize the economic development of the project

area with the environmental protection of the region.

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 resource allocation for monitoring; and

Implementation of the Scheduled plan.

Environmental management plan has been discussed in the later Chapters separately

for Construction phase and occupancy phase.

4.3 IRREVERSIBLE & IRRETRIEVABLE COMMITMENTS OF ENVIRONMENTAL

COMPONENTS

There are no irreversible or irretrievable commitments of the environmental

components as adequate care will be taken to prevent any major impact on the

environmental parameters.

4.6.7 PRESSURE ON LOCAL INFRASTRUCTURE:

During the construction phase, demand of the basic amenities such as water,

power, etc., for the construction labors and construction activities, put pressure on the

existing infrastructure. These impacts are of short-term and of low magnitude limited

to construction phase only. Also excess treated water from the occupancy phase of the

project is utilized for construction activities, dust suppression and watering avenue

plantation etc.,

4.6.8 AIR ENVIRONMENT:

Potential impacts on the air quality during the construction stage will be due to the

fugitive dust and the exhaust gases generated in and around the construction site. Dust

is generated mainly from the following construction activities

Site clearance and use of heavy vehicles, machinery/equipment etc., at construction site;

Procurement and transport of construction materials such as sand, cement, etc., to the construction site;

Operation of construction vehicles and equipments.

The following mitigation measures are proposed to control dust

GI sheets are provided to a height of 5 m all around the project site to control dust;

Water is sprinkled at regular intervals;

SO2 emissions from diesel generators is expected to be low because of usage of low sulfur content diesel;

Use of efficient machinery and schedule maintenance of the construction vehicles and equipments.

4.6.9 NOISE POLLUTION:

Noise is perceived as one of the most undesirable consequences of construction activity.

Though the level of discomfort caused by noise is subjective, the most commonly

reported impacts of increased noise levels are interference in oral communication and

“Green Fields”


disturbance in sleep. Due to the various construction activities, there will be short-term

noise impacts in the immediate vicinity of the project corridor. The construction

activities include

Operation of DG sets;

Concreting and mixing;

Excavation for foundations;

Movement of vehicles carrying construction materials;

Operation of various construction equipments.

These activities are limited to construction period and are only temporary phenomena.

Also the project site is surrounded by open areas; hence no major adverse impacts are

anticipated. Nonetheless the following mitigation measures are proposed

It is proposed to carry out all the noise generating activities during day time;

Proper planning of the movement of vehicular traffic;

Proper and periodic upkeep of construction equipments;

Providing noise reduction gadgets, providing PPE to construction workers to prevent its effect on them.

4.6.10 TRAFFIC CONGESTION:

Suitable temporal segregation of traffic will be undertaken, in order to ease the load

of traffic in the region. Adequate parking facilities are proposed within the project.

4.6.11 SOIL/LAND ENVIRONMENT:

Soil erosion at the project site during the construction phase will be controlled by

adopting the following measures

1. Pitching and paving of slopes and kerbing is done as structural controls to divert and prevent storm water from entering exposed soils.

2. Grit and sediment removal facilities with sediment traps are provided in the storm water drains to prevent run-off contamination.

3. Top soil is stacked and will be reused for landscape development.

4. The spillage of oil from the machinery or cement residual from concrete mixer plants might contaminate the soil if not properly collected and disposed off. Collection trays are provided to collect oil dripping from construction machineries.

“Green Fields”


4.6.12 STAKING AND DISPOSAL OF CONSTRUCTION MATERIAL:

Staking of construction materials shall be confined to the project site only and also

suitable enclosures shall be provided, hence no impacts on surrounding land is

envisaged. About 500 cum of construction debris generated will be used as preparatory

for road formation within the project site. Disposal of construction waste is likely to

cause unaesthetic view, unhygienic conditions, choking of nearby drains etc., such

impacts are short term. The severity of such impact will depend upon the magnitude

and type of construction waste.

4.6.13 WATER ENVIRONMENT:

The most susceptible locations for contamination of water during construction are

Waterlogged areas;

Surface and ground water resources close to construction material storage yard, concrete mixer plants and maintenance sites of construction vehicles;

Surface water bodies close to labor camps.

All the construction activities are strictly confined to the project site. The following

measures are undertaken to prevent water quality degradation during construction

phase

Good construction practices is strictly implemented and care is taken to see that no water logging takes place at the project site;

Remedial measures is immediately undertaken to remediate any accidental spills or other unforeseen incidents if any;

The domestic sewage from the construction workers camp is treated in Package STP.

The impacts if any are short term and low in magnitude and confined to the construction site and to the construction period only.

Water requirement of laborers is met by bore well sources and also excess treated water from the occupancy phase of the project will be used for water avenue plantation / will be given for others construction project.

“Green Fields”


4.6.14 PUBLIC HEALTH AND SAFETY:

The project is construction of mixed use development project and all the construction

related activity will be confined to project site area. Hence no health related impacts

are envisaged in the surroundings during the construction phase.

At the project site about 700 people are engaged in the construction activities. Direct

exposure of these people to dust is likely to cause health related impacts. This is

minimized by providing suitable respiratory Personal Protective Equipments (PPE) such

as nose mask with filters etc.,

4.6.15 SOCIO-ECONOMIC ENVIRONMENT:

The construction activities will benefit the local population as it creates

employment opportunities. The proponents have given preference to local

people with both direct and indirect employment.

The social impacts during the construction stage could result due to influx of migrant

workers and associated induced development. This will ensure a rise in the consumption

of consumer goods in the local area, which will tend to boost up the local economy. All

the activities related to construction work are confined to the project site only; hence

no adverse social impacts are envisaged in the surrounding areas due to the project.

4.7. IMPACTS DURING OCCUPANCY PHASE:

During the occupancy phase, there would be impacts on the air, water, land

environment and socio-economic aspects. The subsequent sections present the impacts

during the occupancy phase.

4.7.1 AIR ENVIRONMENT:

During occupancy phase the major air pollution sources are DG sets and vehicular

movement. The DGs are operated only during emergencies when there is failure of

power supply from BESCOM. Also the DGs are proposed to be provided with adequate

stack heights as per KSPCB norms to disperse the pollutants high into the atmosphere.

4.7.2 NOISE ENVIRONMENT:

The main sources of noise pollution from the project are DG sets, pumps and vehicles.

High noise generating DG sets will be provided with acoustic enclosures. The DG sets

will be distributed in the Basement floors in a separate acoustically treated room.

“Green Fields”


Green-belt at the project boundary will further act as noise barrier and help in

attenuation of noise.

4.7.3 WATER CONSUMPTION AND WASTEWATER TREATMENT AND DISPOSAL DETAILS,

WATER HARVESTING AND RECHARGE:

The water required for the project will be drawn from bore wells for which permission

is obtained from Karnataka Ground Water Authority (KGWA). The wastewater generated

from the project will be treated in Sewage Treatment plant and the treated sewage

will recycled for toilet flushing, reused for landscape development and for car washing

and road washing etc.,

It is proposed to provide shallow recharge pits along the inner periphery of the boundary

wall of size 5’ dia x 20’ depth. These recharging pits will be filled with graded media

comprising of boulder at bottom and with coarse aggregates to facilitate percolation of

harvested rain water to recharge groundwater table. The recharge pits are

interconnected in such a way that the rain from the first recharge pit is led to the next

pit and so on. The excess rainwater shall be drained off to the storm water drain.

4.7.4 SOLID WASTE:

The domestic solid waste generated from the project will be treated in an organic

converter and the inorganic solid waste will be sent for recycling.

4.7.5 INDUCED DEVELOPMENT:

Since the entire project influenced area will be developed as per the Zoning

regulations, to cater the demand of the living population hence no induced

development is foreseen due to the proposed project.

4.7.6 FLORA & FAUNA:

Project site is vacant land and no trees are proposed to be felled in the project and no

major threat to the flora & fauna is not envisaged as the project is developed in area

located in Commercial Zone of Comprehensive Development Plan (CDP).

“Green Fields”


4.7.7 TRAFFIC IMAPCT:

The project is located Bommenahalli Main Road. The traffic studies conducted on the

approach roads reveal that there will not be major impact by addition of traffic /

vehicle from the project on the existing traffic scenario.

CHAPTER 8

PROJECT BENEFITS

8.1 IMPROVEMENTS IN THE PHYSICAL INFRASTRUCTURE:

The operation of the project provides value addition to the existing infrastructure

facilities such as public transport, water supply, telecommunications etc.,

8.1.1 Employment:

The operation of project and other allied facilities, will improve the employment

opportunities. Both direct and indirect employment is envisaged. The employment

will have positive impact on the local economy thereby increasing the quality of life.

The project activities are likely to generate employment opportunities both during

construction (About 700 workers) and the occupancy phase (About 250 workers). The

occupational profile of nearby settlements is such that the locals can be good source

of labour during both phases. During the construction phase, various manual-laboring

activities can engulf residents of nearby settlements, like the labour camp. People

from these areas, will also have opportunities during the occupancy of the project.

These include ancillary jobs like housekeeping, cleaners, gardeners, helpers, security

staff, etc., the project will increase the economic activities around the area, creating

avenues for direct/indirect employment in the post project period. There would be

a wider economic impact in terms of generating opportunities for secondary

occupation around the project.

Thus the impact on employment due to construction and occupancy of the project

can be considered as “significantly positive”.

8.1.2 Environment:

Total area of 24,111.07 sqm is reserved exclusively for green-belt/landscape

development.

Indigenous / native trees species of different species are proposed to be

planted.

Environmental Infrastructure facilities like Sewage Treatment Plant for treating the

wastewater from the project. Organic Waste Converter for treating the Organic Waste,

the product will be used as manure.

“Green Fields”


Rain water harvesting and Ground water recharging is proposed in the project

to enhance ground water potential. Rain water harvesting, recharging

proposed will help in improving water table in the area.

Water conservation measures adopted in the project will reduce burden on

water resources.

Use of alternative source of energy like solar lighting, solar hot water

generation will assist in reducing load on conventional energy sources.

8.2 IMPROVEMENTS IN THE SOCIAL INFRASTRUCTURE:

The construction activities will benefit the local population as it creates

employment opportunities. The proponents have given preference to local

people with both direct and indirect employment.

The social impacts during the construction stage could result due to influx of migrant

workers and associated induced development. This will ensure a rise in the

consumption of consumer goods in the local area, which will tend to boost up the

local economy. All the activities related to construction work shall be confined to the

project site only; hence no adverse social impacts are envisaged in the surrounding

area due to the proposed project.

8.3 OTHER TANGENTIAL BENEFITS:

1. The project basically fulfills the need of housing in the region.

2. Further the project provides short term and long term employment opportunity

for people residing in the surrounding of the project area.

3. The project may result in creation of additional infrastructure, such as

improvement of existing roads, storm water drains etc.,

4 The project will help in improving local economy generate revenue through taxes,

levies etc.,

CHAPTER 9

ENVIRONMENTAL COST BENEFIT ANALYSIS

9.1 INTRODUCTION:

Cost–benefit analysis (CBA), sometimes called Benefit–Cost Analysis (BCA), is a

systematic process for calculating and comparing benefits and costs of a project for

two purposes

to determine if it is a sound investment (justification/feasibility)

to see how it compares with alternate projects (ranking/priority assignment)

It involves comparing the total expected cost of each option against the total expected

benefits, to see whether the benefits outweigh the costs, and by how much.

In CBA, benefits and costs are expressed in money terms, and are adjusted for the time

value of money, so that all flows of benefits and flows of project costs over time (which

tend to occur at different points in time) are expressed on a common basis in terms of

their "present value."

ENVIRONMENTAL COST-BENEFIT ANALYSIS, refers to the economic appraisal of policies

and projects that have the deliberate aim of improving the provision of environmental

services or actions that might affect (sometimes adversely) the environment as an

indirect consequence.

9.2 COST BENEFIT ANALYSIS FOR THE PROPOSED PROJECT:

CHAPTER 10

ENVIRONMENTAL MANAGEMENT PLAN (EMP)

10.1 INTRODUCTION

The Environmental Management Plan (EMP) is aimed at mitigating the possible adverse

impacts of a project and ensuring the existing environmental quality. The EMP

converses all aspects of planning, construction and occupancy of the project relevant

to environment. It is essential to implement the EMP right from the planning stage

continuing throughout the construction and occupancy stage. Therefore the main

purpose of the Environmental Management Plan (EMP) is to identify the project specific

activities that would have to be considered for significant adverse impacts and the

mitigation measures required.

The construction phase impacts are mostly short term, restricted to the plot area and

not envisaged on a larger scale. In the occupancy 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 following mitigation measures

are recommended in order to synchronize the economic development of the project

area with the environmental protection of the region.

The emphasis on the EMP development is on the following

Mitigation measures for each of the activities causing environmental impact.

Monitoring plans for checking activities and environmental parameters and

monitoring responsibilities.

Role, responsibilities and resource allocation for monitoring, and

Implementation of the scheduled plan.

The scope of EMP is

Collection of data on the baseline environmental quality around the

proposed project site including air, water, noise and land environments.

Identification and assessment of potential adverse and beneficial

environmental impacts due to the proposed project.

Preparation of an EMP to minimize the adverse impacts.

Preparation of post-project monitoring plan to ensure that the EMP

achieves its desired objectives.

DG sets will be installed in an area (utility section)

where the access will be restricted.

The use of PPE (ear plugs) will be mandatory in this

area.

Selection of equipment to ensure that the residual

noise level of < 55 dB (A).

Noise levels will be checked periodically using a

noise pressure level meter.

10.3.4 SOLID WASTE MANAGEMENT

The solid wastes generated during occupancy phase can be categorized as under:

1. Domestic/Residential waste

“Green Fields”


Wet garbage: food waste, lawn mowing wastes etc.

Dry garbage: paper, plastic, bottles, etc.

2. Sludge from Sewage Treatment Plant (STP)

The solid waste generated from the project is estimated to be about 3,290 Kg/day out

of which 1,974 kgs/day (60%) is biodegradable 1,316 kgs/day (40%) is non-

biodegradable/recyclable wastes.

The sludge generated from the STP will be used as manure for landscape development

after taking it through the filter press.

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 so that the waste is not exposed and thus the possibility of

spreading of disease through flies and mosquitoes is minimized.

Adequate number of collection bins, separate for biodegradable and non-

biodegradable waste shall be provided as per The Municipal Solid Waste

(Management and Handling) Rules, 2000. Waste from the bins shall be collected

separately on daily basis.

Collection system should be properly supervised so that quick and regular

removal of waste from the dustbin is practiced.

Door to door collection of the solid wastes shall be done. The biodegradable

wastes will be treated in organic converter and the non-biodegradable wastes-

such as plastic materials, glass & metal wastes are handed over to the waste

recyclers.

Litter waste comprising of fallen leaves and other vegetative material will be

collected at the secured location such that it does not hinder the daily activity

schedule or be washed away by the surface runoff causing choking of drains,

etc., and such waste will be composted and used as organic manure.

10.3.5 STORM WATER MANAGEMENT:

In order to mitigate adverse impacts on water environment due to the surface runoff,

wastewater etc., provisions for adequate infrastructure facilities such as suitable

“Green Fields”


drainage system, wastewater collection and conveyance including treatment and reuse

has been proposed.

As the project location is blessed with fairly good rainfall, it is planned to collect the

storm water at different gradients of the location. There will be rainfall runoff from

building roof-tops, roads and pavements and greenbelt area. Necessary provision will

be made to collect rainfall runoff from the rooftop during rainy season. Rain harvesting

pits/recharge pits at every 30 m (centre to centre) have been envisaged.

10.3.6 LANDSCAPE DEVELOPMENT:

The landscape of project site has been planned to provide a clean, healthy and beautiful

green environment for the people. Landscaping has been designed to achieve a blend

between modern building and various species of plants, shrubs, to create a clean,

healthy and aesthetic environment that provides a visual retreat and relaxation to the

occupants of these buildings. List of tree species proposed to be planted in the project

is detailed in Chapter 2.

Following approach will be adopted for vegetation and ground management.

It is planned to include an ecologically knowledgeable landscape architect as an

integral member of the design team.

Decrease paving and monoculture lawns.

Contain heavy equipment and stockpiling areas to predefined areas.

Design new plantings as diverse communities of species well adapted to the site.

Plant native species of varying ages.

Avoid invasive species and monocultures (same species, same age).

10.3.7 MANAGEMENT OF SOCIO-ECONOMIC ISSUES:

1) Schools for laborer’s children: Temporary education centers (crèche) is provided

for education of the children of the laborers.

2) Health camp for laborer’s family

Periodical health camps is organized to monitor and facilitate the occupants of the

labor camps.

“Green Fields”


3) Public health and safety

Since all the construction related activities are confined to the project site, minimal

health related impacts are envisaged within the project influenced area during the

construction stage.

At the project site on an average of 700 people are engaged, who face direct exposure

to dust and noise generated from the construction activity. This is likely to cause health

related affects such as asthma, bronchitis etc., and hearing impairments respectively.

To minimize these anticipated impacts, suitable actions as listed below will be

undertaken

• Use of water sprinklers to prevent dust from being air borne.

• Providing suitable Personal Protective Equipments (PPE) like mouth mask with

filters, noise mask, helmets etc.,

• Periodic health check-up camp for the laborers is arranged.

• Provision of safety belts.

• In case of injury on-site medical treatment and transport will be organized.

Due to operation of the proposed project, there will be enhancement in public health

and safety.

Regular visit of resident medical officer to take care of the first-aid and primary

medication in case of emergency for occupants and laborers.

First-aid kit with primary medicines will always be available in the medical

centre.

Display of action plan and preparedness measures during emergency situations.

SUMMARY & CONCLUSION

11.1 OVERALL JUSTIFICATION FOR IMPLEMENTATION OF THE PROJECT

The Environmental Impact Assessment studies carried out for the Expansion of

Residential Apartment project is completed. The study conducted encompasses the

various areas of the proposed project starting from the location of the project, its

environmental setting and surrounding area details. This is followed by the detailed

description of the project covering details such as the land-use pattern, built-up area,

car parking facilities proposed and investment on the project. The sources of pollution

from the project viz., sewage generation from the occupants and emissions from the

generators are discussed in detail along with the measures proposed to prevent any

impact on the surrounding environment. Water requirement for the project and

rainwater harvesting and recharging measures proposed are discussed. In addition to

this landscape development options are considered.

The building structural aspects, eco-friendly features of the project, electrical

consumption and the savings achieved due to the usage of unconventional sources of

energy are detailed. The meteorological data and baseline environmental & ecological

features have been evaluated to understand the environmental setting of the project

site.

Traffic studies and its survey have been conducted to ascertain the pattern of traffic

along the approach roads to the project site. The percentage increase in the traffic due

to the proposed project reveals that the net increase in traffic is marginal when

compared with the overall traffic.

Based on the above studies an Environmental Impact and mitigation plan has been

prepared to ascertain the possible impacts of the project on the environmental

parameters like air, water, land, biological and socio-economic environment. An impact

matrix has also been prepared based on the observations of the impacts on the

environment.

An Environmental Management Plan has been prepared covering the environmental

aspect and the management plan required to be adopted by the management not only

during the course of setting up of the project but also during its occupancy phase.

The following conclusions can be drawn from the EIA studies

“Green Fields”


Development of the project will have certain level of marginal impacts on the local

environmental setting, which will not affect the natural environmental setting of

the study zone either drastically or otherwise.

The development of this project will create some direct & indirect employment

opportunities during & after the construction phase.

The development of the project will improve the infrastructure facilities around the

project site.

Mitigation measures are undertaken to prevent adverse impacts on the surrounding

environment like air, water, land and biological.

There shall be economic growth and development at the local and regional level.

To put it in a nut shell the management of M/s. Shrivision Towers Pvt. Ltd., strongly

believes in the concept of sustainable development and understands the impacts of the

project on the environment from the Environmental Impact Assessment studies

conducted. It is committed to construct and establish the project without giving room

for any adverse impacts on the environment and also lays emphasis on the

implementation of the recommendations of the Environmental Management Plan in true

spirits.
