E-waste

E-waste will be generated during operation phase of the project from the staff of Office complex

(i.e. 6,860) . Calculation of E-waste generated during operation phase:

• E-waste generation from 1 unit personal computer (includes desktop, portables and CPU)

= 8 kg

• E-waste generation from keyboard + Mouse = 0.8 kg

• E-waste generation from hardcopy device (printers, scanner etc.) per unit = 8.6 kg

• E-waste generation from Laptop = 3 kg

• Average life period of a PC is considered as 5 years, for laptop average life period of 3

years is considered, for hard-copy devices, keyboard and mouse average life period of 2

years is considered.

• Total staff is estimated to be 6,860 so accordingly we consider 6,000 Nos. of personal

computers and 860 Nos. of laptops. 1 Hard-copy device is considered per 15 PC/laptop,

so 457 Nos. of hardcopy devices are considered.

Estimation of E-waste:

=6,000 X 8 X 1/5 +6,000 X 0.8 X 1/2 + 860 X 3 X 1/3 + 457 X 8.6 X 1/2

= 9,600+ 2,400 + 860 + 1,965.1= 14,825.1 or 14 Tonnes/ year.

CHAPTER 3: DESCRIPTION OF ENVIRONMENT

3.1 INTRODUCTION

Information on the existing environmental status is essential for assessing the likely

environmental impacts of the project. In order to get an idea about the existing state of the

environment, various environmental attributes such as meteorology, air quality, water quality,

soil quality, noise level, ecology and socio-economic environment have been studied/

monitored.

3.2 STUDY PERIOD

With the permission of SEAC, the baseline environment study carried out for the project

"Knowledge Park/IT Park" GMADA, Sector-66, 82 & 83, SAS Nagar, Mohali, Punjab during

post-monsoon season October to December 2013 has been used for this project with

additional one month study (12th May, 16 to 12th Jun., 16). The monitoring locations selected

for GMADA project fall within the 10 km radius of proposed ‘World Trade Centre’

Commercial project by WTC NOIDA Development Company Pvt. Ltd.

As per the MoEF&CC Office Memoranda dated 12th April 2016, the primary data used for

and EIA study should not be older than three years.

Apart from field study, additional data was also collected from secondary sources like

irrigation department, India Meteorological Department (IMD), Central Ground Water Board,

Geological Survey of India, State Ground Water Department, State Pollution Control Board,

Census of India and Local Forest Department, Non - Government Agencies, etc.

3.3 STUDY AREA

The present report covers baseline environmental data generated in the core and buffer zone

(10 Km radius all around the project site for land use and the sample selection for monitoring

are done within 5 km radius of the project site).

3.4 BASELINE MONITORING OF ENVIRONMENTAL COMPONENTS




In order to get an idea about the existing state of the environment, various environmental

attributes such as meteorology, air quality, water quality, soil quality, noise level, ecology

and socio-economic environment have been studied/monitored.

3.4.1 METEOROLOGY

Meteorological data was generated during the October- December 2013. The following

parameters were recorded at hourly intervals continuously during monitoring period:

Air Temperature

Wind speed

Table - 3.1 gives summarized meteorological data for the monitoring period (Oct- Dec 2013).

Table 3.1: Meteorological Data for Oct 2013 to Dec 2013

3.4.2 AIR ENVIRONMENT

The prime objective of the baseline study with respect to ambient air quality is to establish

the present air quality and its conformity to National Ambient Air Quality Standards. This

data has been further used during impact assessment to predict the final air quality. This

section describes the sampling locations, frequency of sampling and methodology adopted for

monitoring ambient air quality.

To quantify the impact of the project on the ambient air quality, it is necessary at first to

evaluate the existing ambient air quality of the area. The existing ambient air quality, in terms

of Particulate Matter – 10 (PM10), Particulate Matter- 2.5 (PM2.5), Sulphur-dioxide (SO2),

Oxides of Nitrogen (NO2), and Carbon Monoxide (CO), has been measured through a

planned field monitoring.

To assess the ambient air quality level, 5 (five) monitoring stations were set up. Table - 3.2

3.4.2.1 Monitoring Schedule

Ambient air quality monitoring was carried out twice a week with a frequency of 24 hours for

12 weeks.

3.4.2.2 Methods of Sampling and Analysis

The brief methodology of the parameter analyzed is as follows:




I. Particulate Matter (PM2.5): (CPCB Method) Particulate Matter (PM2.5) was analyzed

by Fine particulate Sampler Envirotech Model APM 550. PM 2.5 was collected on 47mm

diameter filter paper. The mass concentration of (PM2.5) fine particles in ambient air was

calculated as the total mass of collected particles divided by the volume of air sampled.

II. Particulate Matter (PM10): Particulate Matter (PM10) was carried out by respirable

dust sampler envirotech Model APM 460 BL. The cyclone of this instrument is used for

fractionating the dust into two fractions. PM 10 dust is accumulated on the filter paper

(8ʺ×10ʺ size) while coarse dust is collected in a cup placed under the cyclone.PM 10 was

calculated as per IS: 5182 (Part 23):2006. The mass of these particles was determined by the

difference in filter weight prior to and after sampling. The concentration of PM 10 in the

designated size range was calculated by dividing the weight gain of the filter by the volume

of air sampled.

III. Sulphur dioxide (SO2): SO2 was monitored with the help of APM 411 assembly

attached with APM 460 BL using the impinge. It was absorbed by aspirating a measured air

sample through a solution of Potassium tetrachloromercurate (TCM). This procedure resulted

in the formation of a dichlorosulphitemercurate complex. The complex was made to react

with pararosaniline and methylsulphonic acid. The absorbance of the solution was measured

by means of spectrophotometer.

IV. Nitrogen Dioxides: NO2 was monitored with the help of APM 411 assembly attached

with APM 460 BL using the impinge. It was collected by bubbling air through a solution of

sodium hydroxide and sodium arsenite. The concentration of nitrite ion produced during

sampling was determined colorimetrically by reacting with the nitrite ion with phosphoric

acid, sulphanilamide and NEDA and absorbance of highly colored azo-dye was measured at

540nm.

V. Carbon Monoxide: It is measured using CO Analyser. This analyser is used to

measure CO in ambient air, in the range of 0-200 ppm (220 mg/m3) to a sensitivity of 0.05

ppm (55µg/m3). The Serinus 30 combines the benefits of Microprocess control with Non-

Dispersive Infrared Spectrophotometry technology. CO concentration is automatically




corrected for gas temperature and pressure changes. CO was monitored on hourly basis

whereas other parameters were monitored on 24 hourly bases.

3.4.2.3 Results and Discussions

The monitoring reports are enclosed as Annexure-6 and summarized in the tabular form

below. The results when compared with National Ambient Air Quality Standards

(NAAQS) of Central Pollution Control Board (CPCB) for "Industrial, Residential,

Rural and Other Areas" show that the average values of ambient air quality parameters are

well within the stipulated limit.

The results of ambient air quality monitoring for Oct-Dec 2013 for “Knowledge Park” project

are summarized in the Tables below:

3.4.3 NOISE LEVELS

Noise is one of the most undesirable and unwanted by-products of our modern life style. It

may not seem as insidious or harmful as air and water pollutants but it affects human health

and well-being and can contribute to deterioration of human well-being in general and can

cause neurological disturbances and physiological damage to the hearing mechanism in

particular. It is therefore, necessary to measure both the quality as well as the quantity of

noise in and around the site.

To assess the ambient noise quality level, 5 (five) monitoring stations were set up. Table - 3.4

gives location of the ambient noise quality monitoring stations gives location of the ambient

air quality monitoring stations and a composite map showing the ambient noise quality

monitoring stations of both the sites is attached as Annexure - 5 (b).

3.4.3.1 Methodology

The intensity of sound energy in the environment is measured in a logarithmic scale and is

expressed in a decibel, dB (A) scale. In a sophisticated type of sound level meter, an

additional circuit (filters) is provided, which modifies the received signal in such a way that it

replicates the sound signal as received by the human ear and the magnitude of sound level in

this scale is denoted as dB (A). The sound levels are expressed in dB (A) scale for the

purpose of comparison of noise levels, which is universally accepted by the international

community.

Noise levels were measured using an Integrating sound level meter manufactured by Pulsar

Instruments Plc, Model No. 91 (SL.No.B21625). It has an indicating mode of Lp and Leq.

Keeping the mode in Lp for few minutes and setting the corresponding range and the

weighting network in “A” weighting set the sound level meter was run for one hour time and

Leq was measured at all locations.

The day noise levels have been monitored during 6.00 am to 10.00 pm and night noise levels,

during 10.00 pm to 6.00 am at all the 5 locations, which covers residential areas, commercial,

industrial areas, silence area if available within 5 km radius of the study area.

3.4.3.2 Sampling Locations

A preliminary survey was undertaken to identify the major noise generating sources in the

area. The noise survey was conducted to assess the background noise levels in different

zones. Gazette Notification (S.O. 123(E)) of MoEF dated December 14, 2000 on ambient air

quality standards has different noise levels for different zones viz. project site, industrial, and

residential zones. Four sampling locations were selected for the sampling of noise levels. The

sampling locations are given in Table - 3.4 below. The noise quality at the GMADA site and

other locations within the 10 km impact zone was monitored during Oct 2013 and additional

one month baseline study (12th May to 12th June, 2016) was conducted on project site. The

monitoring reports are given in details in Annexure-6 and summarized in the tabular form.

3.4.4 WATER ENVIRONMENT

3.4.4.1 Water Quality

Water quality assessment is one of the essential components of EIA study. Such assessment

helps in evaluating the existing health of water body and suggesting appropriate mitigation

measures to minimize the potential impact from development projects. Water quality of

ground water has been studied in order to assess proposed water-uses in construction,

drinking, cooling and horticulture purpose.

The water quality at GMADA site and other locations within the 10 km impact zone was

monitored during Oct 2013 to Dec 2013 and additional one month baseline study (12th May

to 12th June, 2016) was conducted on project site. The locations of the monitoring sites are

depicted in composite map is enclosed as Annexure 5 (c) and the result of the monitoring

and analysis of groundwater is presented in the Annexure 6.

3.4.4.2 Sampling Frequency and Sampling Techniques




Samples were studied at monthly intervals in the study period. Quality of ground water was

compared with IS: 10500: 1991 (Reaffirmed 1993 with Amendment No.3 July 2010) for

drinking purposes. Surface water quality was analyzed for parameters as mentioned in the

‘Annexure IV of CPCB guidelines’ and it was rated according to the CPCB Water Quality

Criteria (Designated Best Use). Water samples were collected in a 5 liter plastic jerry can and

500 ml sterilized clean glass bottles for physio-chemical and bacteriological tests

respectively. GW sampling was done after flushing out the source (minimum 10 minutes) to

get the fresh ground water and grab sampling method was used. River water samples were

collected about 10cm below the water surface. All sampling, preservative and sample

handling techniques were in accordance with APHA for Examination of Water &

Wastewater/ IS: 3025 (Part-1)/ IS: 1622. The samples were analyzed as per Indian standard

/APHA latest edition. The surface water quality is compared with CPCB water quality criteria

mentioned in Table 3.8

The water quality in the impact zone was assessed through physico-chemical and

bacteriological analysis of ground samples. The results have been compared with the drinking

water quality standards specified in IS: 10500.

3.4.4.3 Results and Conclusion

The result of Ground water quality monitoring of Oct-Dec 2013 is summarized in Table 3.9

(a-c). Ground water quality monitoring has also been done from 12th May to 12th June 2016

at Project site (World Trade Centre) and two more location i.e., Saneta and Nagari.

Core zone is taken as project site. From the above table it is clear that water at project site is

neutral (pH- 7.49-7.82). Other parameters T.D.S (570-630 mg/l), Chloride (55-72 mg/l) and

Magnesium (26-31 mg/l) are within the permissible limits as per drinking water standards

(IS-10500:2012). Water can be used for domestic purposes after treatment with RO and using

disinfectant

Comparing the values of pH, DO, BOD and total coliforms with ‘Use based classification of

surface waters’ published by Central Pollution Control Board; it can be seen that the

analyzed surface waters can be compared with class ‘E’ and can be used only for irrigation,

industrial cooling, controlled waste disposal. Bacteriological examination of surface water

indicates the presence of total coli forms, which may be due to human activities observed

during the study period.

3.4.5 LAND ENVIRONMENT

The land use pattern of the area is mainly settlements, agricultural land, open land, open

scrub and water bodies.

3.4.6 BIOLOGICAL ENVIRONMENT

Ecological assessment of the study area of around the project site was conducted in the post

monsoon season. A participatory and consultative approach was followed for the Ecological

Assessment. A field visit was undertaken for the ecological assessment and survey of the

vegetation in the study area.

For the purpose of floristic surveying the vegetation, quadrates were laid to record

phytosociological features of the vegetation. Detailed notes on ecological features, including

the habitat types were also taken along the selected locations. The fauna in the study area

were also assessed through phyto-sociological survey. Identification process of biodiversity

aspects of flora and fauna are done for estimating flora and fauna species diversity.

Besides measuring these parameters, other biodiversity aspects in the form of endemic status,

conservation status and life form have been enumerated. For all the plant species found in the

area during ecological survey, Red Data Books of the Botanical survey of India have been




screened to verify their conservation status. For wild animal species schedule 1 of the

Wildlife Protection Act (1972) has been screened.

Terrestrial Ecology

The study of terrestrial ecology within the study area has been carried out through field

investigation.

Plants / animals and environment are inter-related to each other. With the change in

environmental conditions the vegetation cover as well as animals reflects several changes in

its structure, density and composition.

The main species of plants found in the study area are Dalbergia sissoo, Morus alba,

Prosopis spicigera, Acacia nilotica, Parkinsonia aculeate, Acacia gamesiana, Butea

monospema, Zizyphus mauritiana, Albizia lebbek, Melia benghlensis, Tamarix articulate,

Melia azedarach and Azadirachta indica. Among the grasses, Desmotachya bipinnata and

Saccharum spontaneum are abundant. Other species found are shown in Table 3.13

3.4.7. SOCIO ECONOMIC IMPACT ASSESSMENT

3.4.7.1 Introduction

Socio-Economic Impact Assessment (SEIA) refers to the systematic analysis of various

social and economic characteristics of the human beings living in a given geographical area

during the period of study. The geographical area is called Study Area or Impact Area. SEIA

is carried out separately but concurrently with Environment Impact Assessment (EIA). The

study area consists of core and buffer area encircling the project area. The Socio-Economic

Impact Assessment focuses on the likely effect of the project on social and economic well-

being of the community. The impact may be direct or indirect, positive or negative.

OBJECTIVES OF SEIA:

The prime objective of the current study is to assess the likely impact of the proposed project

on socio-economic characteristics of people living in the study area. Further, it is to be

established whether the impact would be direct or indirect. Furthermore, it is to be examined

whether the said impact would be positive or negative. Lastly, it is to be comprehended if the

impact is positive how long it would sustain or if it is negative how soon the same could be

eased.

SCOPE:

The Scope of the study is as follows:

a) To collect baseline data of the study area

b) To comprehend socio-economic status of the people living in the study area.




c) To assess the probable impact of the project on social and economic aspects in the study

area.

d) To evaluate the likely impact of the project on Quality of Life of the people living in the

study area.

e) To ensure sustainability of the positive impact.

f) To suggest mitigation measures and agency responsible for taking action in case of

adverse impact.

METHODOLOGY:

For Socio-Economic Impact Assessment of the proposed project, we carry out systematic

analysis of the various socio-economic characteristics, both in terms of quality and quantity.

Accordingly, both qualitative and quantitative data was collected from secondary sources.

The secondary data was collected from the published data/information of the Census

Authority. Records of the state and district administration were also referred to.

For collection of primary data, a sample survey was conducted in the study area. In each

selected habitation (village/town), a specified number of representative households were

selected scientifically for collection of information through face to face interview with head

of the household or any responsible member of the family.

Census-cum Sample Survey in the Core Area

As the likely impact of the project will be greatest in the core area and it diminishes

progressively when move away from the core area to the periphery of the study area, a

Census-cum-Sample Survey was conducted in the core area for the collection of socio-

economic data.

It is treated as a Census Survey because all the villages/towns located in the core area

were surveyed for the collection of information. Further, in each village/town a

household survey was conducted by drawing representative samples from a list of

households prepared. Since, collection of information from all the households in a

village/town is time consuming and expensive, the Sample Survey approach was adopted

for collection of information from the selected households in the villages/towns.




Sample Survey in the Buffer Area

In the buffer area, where the impact of the project progressively reduces with the distance

from the project area, Sample Survey was conducted for the collection of data.

Sample Design

Two-Stage Sampling Design was adopted in the study area. The First Stage Units were

Census villages/towns and the Ultimate Stage Units were households in the selected

villages/towns.

Selection of First Stage Units (Villages/Towns)

In buffer area the sample villages/towns were selected from the list of Census villages/towns

by adopting the method of Probability Proportional to Size (PPS), the size being number of

households in a given village/town.

Selection of Ultimate Stage Units (Households)

The sample households were selected from the list of households by adopting the method of

Circular Systematic Sampling. This method was adopted since the sampling frame i.e. the

complete list of households was readily available.

SURVEY INSTRUMENTS:

The following Schedules/Questionnaires were developed for collection of Primary data:

Questionnaire-1A: Village Particulars

Questionnaire-1B: Town Particulars

Questionnaire-2: Household Particulars.

Each Questionnaire is divided into several blocks and there are both open-ended and closed-

ended questions.

CHAPTER 4

ANTICIPATED ENVIRONMENTAL IMPACTS & MITIGATION

MEASURES

4.1 INTRODUCTION

This chapter discusses identification and appraisal of various environmental impacts due to the

Commercial Project. Generally, the environmental impacts can be categorized as either primary or

secondary. The development, construction and functional/operational phase of the project comprise

various activities, each of which may have some impact on environmental parameter. Various

impacts during the development, construction and operation phase on the environmental parameters

have been studied to estimate the impact on environment.

In development phase, basic infrastructure facilities like internal road, sewerage system, storm

water drainage, street lighting, etc. will be developed.

For proper evaluation and assessment of the environmental impacts due to development,

construction and functional phase of project understanding to the various activities associated with

the Project is essential. Various activities related to the project would be different, in terms of

nature during the development, construction and functional phase.

The impact identification and prediction process aims to:

Identify potential source or cause of impact throughout the life of project.

Characterize the potential impacts affecting a target or receptor (physical, human and socio-

economic).

Assess the potential of changing likelihood of impact through Environmental Management

Plan (EMP)

Prediction of the impacts due to the development, construction and functional activities

encompass the developmental processes to be undertaken during construction and

functional phases.

For each component of environment (such as ambient air quality, water quality, soils, land, etc,) the

potential impacts of activities during development & construction and functional phases have been



identified. Pollution sources & its characteristics, the potential impacts and magnitude of the

impacts have been assessed and discussed in detail in following sub sections. In each case,

cognizance has been taken to mitigation measures inherited in the development & construction and

functional phase.

Impact on various environmental parameters can be broadly categorized into two phases, namely:

Construction phase: Impact during this phase may be regarded as temporary or short term;

and

Operation phase: Impact during this phase shall have long-term effects.

Various impacts during these two phases have been envisaged and are discussed in the subsequent

sections.

4.2 IMPACT MATRIX

Various activities from the project are likely to have some impact on the environmental constituents

during its construction as well as operational phase. The impact assessment matrix given in Table

4.1 reveals the impact associated with each activity of the project on various environmental

parameters during construction and function phase respectively before any mitigation measures are

implanted. To assess the severity of the impacts, they are categorized as follows:

4.5 ASSESSMENT OF ENVIRONMENTAL IMPACTS DURING DEVELOPMENT AND

CONSTRUCTION PHASE

4.5.1 Topography

Impact: Topography around the project is fairly flat. Therefore, topography and physiography of

the area will not be affected due to leveling during the construction and post construction phase

of the project. Hence, no significant impact is anticipated on the topography and physiographic

from project.

Mitigation Measure: Since there is no significant impact on topography from the project, no

detailed mitigation measures are proposed. It is however proposed that apart from the proposed

plantation greens, turfing with local species will be carried out extensively.



4.5.2 Land Use Pattern

Impact: Land use of the project site is commercial and has been allotted by Greater Mohali

Area Development Authority. Therefore, land use pattern of the area will not be affected

significantly by project.

4.5.3 Land Environment

Impact: The soil excavated during construction will be first temporarily stored in an area

earmarked and then shall be used to fill up low lying area in and around the project site and rest

of the soil shall be transported by road to fill up low lying areas elsewhere. Proper drainage

system shall be provided to deal with the storm water in case of rain. The impact on soil during

construction phase will be marginal and reversible in the nature.

Mitigation: It is proposed to remove vegetative cover only from the specific site on which

construction is to take place and allowing minimal disturbance to the vegetation in adjacent

areas. Land clearing activities only confined to necessary areas. The top soil will be stripped

from constructional areas and stockpiled for later reuse in landscaping. The number, frequency

and area of movement of heavy machinery will also be restricted.

4.5.4 Water Environment

4.5.4.1 Surface Water Quality

Impact: The primary concerns relating to surface water quality associated with construction

activities are pointed out below:

Runoff related to unpaved and excavated areas during the rain shower.

Sediments transported to runoff from the construction site.

Run off related to area where lubricant, fuel other materials are stored, used and disposed, off.

Surface water quality may be affected with the discharge of the runoff from the project site. The

impact to the surface water bodies could arise from the increased soil erosion from excavated site

only causing increase in the suspended particles and turbidity of runoff water from the site.

However, this impact will be temporary in the nature and would be observed in first rain only



and as soon as rain is over excavated soil at site would be stabilized. Therefore, the surface water

quality during rains will be impacted marginally for very short duration.

Mitigation Measures: During the construction phase, surface water quality is likely to be

affected due to soil erosion during first rain and generation of wastewater mainly from

construction labour camp. However, this phenomenon will be temporary and restricted to close

vicinity of construction site. The impact on surface water quality can be minimized by adopting

following measures;

Excavation during dry season and proper management of excavated soils,

Clearing all debris from site as soon as construction is over.

By providing proper hutment and toilet facilities for construction labour,

Through the proper disposal of waste water generated at site.

4.5.4.2 Ground water Quality

Impact: Building construction involves a large variety of construction activities. Wastewater

would be generated from concreting, plastering, cleaning and polishing, internal decoration and

similar activities. Direct discharge of wastewater into storm drains pollutes the water quality of

receiving water body. Ground water quality could be polluted by debris and waste generation.

Mitigation:

A suitably designed wastewater collection system should be provided on site to divert all

the wastewater to the sedimentation facility.

If necessary, pH adjustment should be undertaken to neutralize the wastewater.

Good housekeeping should be adopted to reduce generation of construction wastes and

the potential water pollution

Drainage channels should be provided on site to convey storm water to sand/silt traps for

removal of soil particles

Regular cleaning and maintenance of the sediment removal facilities should be

implemented to ensure that the facilities are in normal function at all times



Provision of earth bunds or sand bags in areas where a large amount of exposed soils

exists would be required

The construction works should be properly programmed to minimise soil excavation in

rainy seasons to prevent soil erosion from exposed soil surfaces

Excavated trench should be backfilled in short sections

Exposed stockpiles should be covered with tarpaulin or impervious sheets before a

rainstorm occurs

Suitable locations should be selected on site to place the stockpiles so as to avoid release

of materials into the drainage channels

Final surface of earthworks should be compacted and protected by permanent work

Intercepting channels should be provided to prevent storm runoff from washing across

exposed soils surfaces; and

It is recommended to pave haul roads with concrete and protect temporary access roads

using crushed stone or gravel.

4.5.4.3 Surface and Ground Water Hydrology

Surface Water Hydrology

Impact: The project site is not falling in flood plain. Runoff during rains takes way to natural

drain and in storm water drains laid in the area. During construction phase, there is no impact

anticipated on the drainage pattern of the project area.

Mitigation Measures: Project proponent will ensure no interception on water runoff flow routes

and drainage pattern of the area throughout the construction of the project by providing adequate

water channel.

Ground Water Hydrology

Impact: Water requirement during construction phase will vary depending upon construction

activities and will be met through authorized private water tankers. Water will be required for

site preparation activities dust settlement, consolidation, compaction and curing as well as



building construction and drinking water requirement. The requirement of construction water

will not put sudden pressure on the available ground water recourses of area. Therefore, impact

on ground water resources will be insignificant during construction of project.

Mitigation Measures: Although no impact is anticipated on the groundwater regime, it is

proposed to carry out the following to further minimize the water demand:

Curing water will be sprayed on concrete structures and free flow of water not allowed.

After liberal curing on the first day, all concrete structures will be painted with curing chemical

to save water to stop daily water curing hence save water.

Concrete structures will be covered with thick cloth/gunny bags and then water sprayed on

them to avoid water rebound and ensure sustained and complete curing.

Ponds will be made using cement and sand mortar to avoid water flowing away from the flat

surface while curing.

Water ponding will be done on all sunken slabs. This will also highlight the importance of

having an impervious formwork.

4.5.5 Air Environment

Emission Source: The potential sources of air emissions during the construction and

development phase of the project will be as follows:

Dust from earth works (during site clearance and preparation);

Emissions from power generator at site;

Emissions from the operation of construction equipment and machines;

Fugitive emissions from vehicles running to site;

Fugitive emissions during the unloading of material at the site;

Fugitive emissions during mixing of cement with other building materials during development

and construction activities;

Air emissions other than dust arise from combustion of hydrocarbons. The pollutants of

concerns are NO2, SO2, CO, particulate etc.



Potential Impacts: Ambient air quality effects are normally assessed in relation to their

potential to cause;

Health deterioration and nuisance to local communities

Health deterioration amongst onsite workers

Assessment of the impacts from Dust Emissions: During the excavation of channels,

foundations, unloading of construction material, cement bags and mixing of cement with other

building materials such as brick and silica dust, wood dust, fugitive dust emissions may be

emitted at construction site. During construction, curtaining floors from all sides will be done to

prevent cement dust from becoming airborne. It may be noted that all the emissions will be in the

form of coarse particulate matter and settle down ultimately in closed vicinity of construction

site.

Assessment of the impact from Diesel Generators: Emissions from the D.G. Set during

construction phase may cause some localized impact on ambient air quality for short duration, as

it will be operated during power failure only. It may be noted that the D.G. Set power will be

used to operate construction equipment only if required. Adequate height of stacks and acoustic

erective will be provided to the D.G. Set as per guidelines of CPCB to facilitate the dispersion of

flue gases into the atmosphere.

Mitigation Measures: It is proposed to provide adequate dust control systems in the form of

installation of batch plants, and loose material handling in covered sheds. Dust suppression

system is also to be provided where necessary. Ultra-low sulphur based DG sets will be used. It

is further proposed to cover scaffolding, hosing down road surfaces and cleaning/washing of

vehicles especially during the dry season. Avenue and curtain plantation on the internal roads

and peripheral plantation around the site will also be developed for mitigation of air pollution.



4.5.6 Noise Environment

During the construction phase of project, noise will be generated from various sources. Some

major sources of noise generation at project site are listed here:

Generation of noise during movement of vehicles carrying materials and loading & unloading

activities.

Generation of noise from excavation machines, concrete mixer and other construction

machines,

Generation of noise during the operation of D.G. Set

Generation of noise during concreting, hammering, etc.

All the above-mentioned sources of development and construction activities would be

intermittent and experienced occasionally. It may also be noted that most of the construction

activities would be carried out only during the daytime.

The expected noise levels from various activities are given hereunder:

From vehicles bringing materials to the site 70 dB (A)

D.G. Set 85 dB (A)

Excavation 80 dB (A)

Concrete Mixtures 80 dB (A)

Hammering 85 dB (A)

Resultant Noise Level:

The combined effect of above sources can be determined as per the following equation:

Lp (total) = 10 log (10(Lpl/10) + 10(Lp2/10) + 10(Lp3/10) +……..) ……. (1)



Where: Lp1, Lp2 and Lp3 are noise pressure level at a point due to different sources in dB (A). The

resultant maximum noise level for the above sources as calculated using equation (1) is 89.3 dB

(A).

For an approximate estimation of dispersion of noise in the ambient air from the sources point, a

standard mathematical model for sound wave propagation is used. The sound level generated by

noise source decrease with increasing distance from the source due to wave divergence. An

additional decrease in sound pressure level from the source is expected due to atmospheric effect

or its interaction with objects in the transmission path.

For hemispherical sound wave propagation through homogenous loss of free medium, noise

levels at various locations can be calculated due to different sources using model based on the

first principles as per the following, equation:

Lp2 = Lp1 -20 log (r2) – 8 ………. ( 2 )

Where: Lp2 and Lp1 – Sound Pressure Level (SPLs) at points located at sources and at distance

of r2 from the source respectively in dB (A).

Assuming no environmental attenuation factors, noise modeling has been done, which shows

that noise level will be mingle with baseline noise level with in short distance.

The noise produced during, development and construction phase will have temporary impacts on the

existing, ambient noise levels at project site but restricted to small distance and only during daytime.

Therefore, the impact of noise levels on surrounding area will be insignificant during the development

and construction phase.

Mitigation: To minimize impacts of noise generation following measures will be adopted:

Provision of Personal Protective equipments (PPE) such as muffles/plugs to the workers.

Acoustic enclosures to be provided for compressors for drills and rock cutter.

DG set for backup power to be provided with adequate acoustic enclosure and to be fitted with

muffler to reduce the noise in adherence with the regulatory equipments.

All plants and construction equipments shall be fitted with noise control measures.



Servicing of all construction vehicles and machinery to be done regularly and during routine

servicing operation, the effectiveness of exhaust silencers will be checked and if found

defective to be replaced.

To have the provisions of noise barriers in form of dense tree belt around the periphery and

particularly facing residential area. Shrubs can reduce noise by about five to ten decibels-or

about 50 percent as perceived by the human ear, (According to the USDA National Agro

forestry Center). Some Examples include Neem, Manngo, Tamarind, Gulmohar , Peepal,

Ashoka

The DG sets should also be provided with proper exhaust muffler with insertion loss of

minimum 25 dB (A).

Vehicle for bringing construction material at site shall conform to the noise emission standards

and to be operated during non peak hours.

Ambient noise level monitoring shall be conducted at suitable locations at periodic intervals

during construction phase to conform to the stipulated standards during both day and night

time. Data shall be reviewed and analyzed by the project manager for adhering to any strict

measures.

4.5.7 Terrestrial Ecology

Impact: There is no loss of forestland due to the development of proposed project. No tree felling is

involved, as the site is devoid of vegetation.

Birds and other domesticated biodiversity observed near the project site are common and already

adapted to thrive in human - colonized habitats. The project will not have any major negative

ecological impact.

Mitigation Measures: However, it is to develop extensive green areas/ open area in the project site to

improve the aesthetics of the area which will also help in reduction of air pollution, noise pollution and

provide suitable habitat for local birds and animal species.



4.5.8 Economic Impacts

Impact: Relatively long-lived economic impacts of the development and construction phase are likely

to be experienced in local area for the duration of construction phase as workers make everyday

purchases from local traders in nearby areas. This is likely to give a short-lived stimulus to the traders

that may disappear as soon as the construction is complete. Noticeable, flow-on economic impacts

will be experienced in other sectors of economy as a result of purchase of construction materials and

the payment of wages and salaries to the personnel engaged in the development and construction of

colony. Once the development and construction of the project is complete, there will be some long-

term positive impact on the economic structure of the area. People in the area will get direct and

indirect employment opportunities and other benefits from the proposed project. Therefore, overall

positive impact is anticipated on economy of the area due to development and construction activity of

the Project.

4.5.9 Socio-Economic

During the development and construction of project, about 200 to 300 skilled and semiskilled and

unskilled workers per day will get direct employment opportunity, which will have beneficial impact

on the local people and improve socio-economic conditions of the area.

4.5.10 Construction Camp

Impact: During the development and construction phase, most of the laborers will be from local areas.

Therefore, laborer camps will be constructed to accommodate the laborers at the project site. This may

lead to sanitation problems in the absence of adequate facilities.

Mitigation: Suitable measures will be taken at the construction camps to mitigate anticipated impacts

due to temporary accommodation of laborers such as provision of adequate drinking water, adequate

toilet facilities, water and solid waste disposal system.

Other safety precautions to be maintained at work site including provision of PPEs, guarding of

dangerous machine parts, maintenance of equipments as hoists and lifts etc, and adequate provision of



different types of fire extinguishers will be made. All applicable rules and regulations pertaining to

workplace health and welfare of workers will be adhered to.

4.5.11 Solid Waste Management

Impact: The construction waste includes debris, concrete (often recycled and reused at the site), steel

and other metals, pallets, packaging and paper products, wood beams, joists, studs, baseboards,

cabinets and cupboards, railings, brick, doors and casings, interior windows, bathroom fixtures, light

fixtures, ceiling grid and tile, furnishings. All wastes generated during the construction phase shall be

collected and segregated for disposal as per the standard practice.

During the development and construction phase, some amount of debris, cuttings of construction

materials may be observed at construction site. However, the quantity of these waste materials would

be very small and limited up to the construction site only. There will be no contamination due to this

waste as it will be collected time to time during construction phase and disposed accordingly.

Mitigation Measures: After due waste segregation, recyclable wastes will be sold off to scrap dealers

and vendors, while inert wastes will be disposed off in landfills. Hazardous wastes will be disposed off

as per the provisions of the Hazardous Wastes (Management & Handling Rules, 1989).

4.5.12 Transport Linkage and Traffic

Impact: During development and construction phase, construction labour and construction materials

bringing vehicles will approach the project site. The Project is well connected to neighborhood, where

public transport facility, like, buses and minibuses are easily available in the area as transport linkage.

During construction phase, some impact is anticipated on the transport linkage of the area, however

increase in traffic will not adversely affect the local traffic pattern since the site is well connected by

broad road and present traffic load on these road are not significant.

Mitigation: Through careful planning, the movement of the heavy vehicles will be scheduled to

reduce load on existing traffic such that the peak hours are avoided. It shall also be ensured that all the



vehicles to the site will be provided with Parking space such that there is no waiting time along the

access roads.

4.6 ASSESSMENT OF THE ENVIRONMENTAL IMPACTS DURING POST

CONSTRUCTION PHASE


Impact: During the operation phase of the project, the soil may get polluted/ contaminated from

littering of various kinds of wastes generated within the site such as food items, paper, wood pieces,

paints, pesticides, oil & grease etc. However, owing to the proposed solid waste management system,

no significant impact is anticipated.

Mitigation Measures: To ensure against any chances of soil pollution, it is imperative to establish a

well-planned solid waste collection system covering all areas of the project site apart from door to

door for the residential units. An identified area shall be designated for storage and segregation of the

wastes which will be treated/ disposed as per their characteristics.

The following steps are proposed to be followed for the management solid waste:

Construction yards are proposed for storage of construction materials.

The excavated material such as topsoil and stones will be stacked for reuse during later stages

of construction

Excavated top soil will be stored in temporary constructed soil bank and will be reused for

landscaping of the commercial project.

Remaining soil will be utilized for refilling / road work / rising of site level at locations/ selling

to outside agency for construction of roads etc.

4.6.2 Water environment

4.6.2.1 Surface water hydrology

Impact: During the post construction phase, no water will be taken from surface water bodies in the

area. Further, adequate drainage will be provided at the project site to channelize the storm water for

rainwater harvesting to recharge the ground water.

The sewage effluents generated from the project will be collected through the sewer line network

provided in the project site for treatment in the Sewage Treatment Plant (627 KLD), and the treated

effluent will be reused within the site Therefore, impact on the surface water hydrology will be

insignificant during the post construction phase.

Mitigation: It is proposed that water will be discharged to sewer after treatment.

Sewerage System

MBBR TECHNOLOGY

An external sewage network will collect the sewage from all units, and flows by gravity to the sewage

treatment plant. Following are the benefits of providing the Sewage Treatment Plant in the present

circumstances:

The process has long retention time and can absorb shock load situation.

Reduced net daily water requirements, source for Flushing and Horticultural purposes by

utilization of the treated water.

Reduced dependence on the public utilities for water supply and sewerage systems.

The process produces a well-oxidized sludge in small quantities only, which can be removed and

used as manure.

c. Treatment Technology

Moving bed biofilm reactor technology is based on the principle of attached growth process. Raw

sewage will be collected under gravity into the equalization tank after allowing to pass through the bar

screen. Screens will be provided in screen chambers and it will be manually cleaned by going down to

a platform. The bar screen, by removing coarse solids from the sewage help in protecting the raw

sewage pump.

Fully submersible centrifugal non clog sewage handling pump will be provided in the collection cum

equalization tank to pump the collected waste water to the next MBBR tanks. Automatic level

controller will be provided in the tank to turn the pump off at the low water level in the tank and to

start the pump when water level is high automatically. Air will be introduced in this tank to prevent

any potential foul smell problem & to provide the mixing of wastewater to avoid the sedimentation of

solids in this tank. Air Grid used for aeration purpose will be non-clog.



The sewage collected in equalization tank is pumped the moving bed bioreactor. There will be two

nos. of bioreactors in series for the efficient working and removal of BODs for the required retention

time. The process inside the moving bed bioreactors consists of adding small cylindrical-shaped

polyethylene/polypropylene carrier elements in aerated basins to support biofilm growth. The small

cylinders are provided with a cross inside the cylinder and longitudinal fins on the outside. The

biofilm carriers are maintained in the reactor by the use of a perforated plate with appropriate slot at

the tank outlet. Air agitation or mixers are applied in a manner to continuously circulate the packing.

The packing may fill 25 to 50 percent of the tank volume. Specific surface area of the packing is about

450-500m2/m3 of bulk packing volume. The waste water from first bioreactor flows by gravity through

the perforated plate/mesh to the next bioreactor kept in series. Inside the bioreactors, aerobic bacteria

grow in an attached growth from around the moving plastic media inside the reactors. The bacteria

have to reduce BOD & COD of waste water in the presence of oxygen provided through the air grids

located at the bottom of the reactors. The Process does not require any return activated sludge flow or

backwashing.

From the bio-reactors, the effluent passes by gravity into the clarifier (Tube Settling Tank). Clarifier

will be a hopper bottom sedimentation tank provided with appropriate size PVC tube deck media. The

suspended solids will settle at the bottom of the tank & clear supernatant will overflow to filter feed

tank through outlet launder. The collected sludge at bottom will be transferred through pumps to

sludge holding tank.

The clear supernatant after clarifier will be collected in to filter feed tank. This tank will act as housing

tank for filter feed pumps. The clarified & dis-infected water will be then fed to filtration unit.

Filtration unit consisting of Dual Media sand filter, activated carbon filter and ultra-filtration system

(optional) will remove the residual impurities such as odor/color, suspended solids, BOD/COD. The

treated water after the filtration unit will be collected in Irrigation cum Flushing water storage tank

from where it is transferred to flushing water tank at terrace & Irrigation System.

Excess sludge from the bottom of the settling tank will be removed and transferred to sludge holding

tank. Air grid will be provided in this tank to avoid conversion into anaerobic conditions, thickening of

sludge and keep sludge in homogenous condition. The digested & thickened sludge will be further



thickened through Sludge Dewatering System (Filter press with screw pump) and disposed off

periodically through closed tanker or can be reused as manure.

Figure 4.3 : Schematic Diagram of STP

4.6.2.2 Ground water hydrology

Impact: During post construction phase, the total water requirement of the Project is approx. 1127

KLD which will be sourced from GMADA. Therefore, no impact is anticipated on ground water

resources due to project.

Mitigation Measures: The rainwater harvesting will recharge groundwater aquifers from the open

areas as well as roof top of the buildings/surface runoff. Treated water from the site will be recycled

for landscaping and flushing. DG set cooling to further reduce demand on freshwater resources.



Water meters conforming to ISO standards should be installed at the inlet point of water sources and at

the discharge point to monitor the daily water consumption. To further lower the water consumption,

options of low flow flushing systems, sensor based fixtures, and tap aerators, etc will be explored.

RAIN WATER HARVESTING

The storm water collection system for the premises will be self-sufficient to avoid any

collection/stagnation and flooding of water. The amount of storm water run-off depends upon many

factors such as intensity and duration of precipitation, characteristics of the tributary area and the time

required for such flow to reach the drains. The drains will be located near the carriage way along

either side of the roads. Taking the advantage of road camber, the rainfall run off from roads will flow

towards the drains. Storm water from building will be connected to adjacent drain by a pipe through

catch basins. Therefore, it has been calculated to provide 8 rainwater harvesting pits at selected

locations, which will catch the maximum run-off from the area.

1) Since the existing topography is congenial to surface disposal, a network of storm water pipe

drains is planned adjacent to roads. All building roof water will be brought down through rain water

pipes.

2) Proposed storm water system consists of pipe drain, catch basins and tanks at regular intervals

for rain water harvesting and ground water recharging.

3) For basement parking, the rainwater from ramps will be collected in the basement storm water

storage tank. This water will be pumped out to the nearest external storm water drain.

4) The peak hourly rainfall is 45 mm/hr. will be considered for designing the storm water

drainage system.

Rain water harvesting has been catered to and designed as per the guideline of CGWA. Peak hourly

rainfall has been considered as 45 mm/hr. The recharge pit is constructed for recharging the water. The

recharge pits of 3 m dia. and 4 m depth is constructed for recharging the water. Inside the recharge pit,

recharge bore will be constructed of sufficient diameter and depth. The bottom of the recharge

structure is kept 5 m above the ground level. At the bottom of the recharge pits, a filter media is



provided to avoid choking of the recharge bore. Design specifications of the rain water harvesting plan

are as follows:

Catchments/roofs would be accessible for regular cleaning.

The roof will have smooth, hard and dense surface which is less likely to be damaged allowing

release of material into the water. Roof painting has been avoided since most paints contain toxic

substances and may peel off.

All gutter ends will be fitted with a wire mesh screen and a first flush device would be

installed. Most of the debris carried by the water from the rooftop like leaves, plastic bags and paper

pieces will get arrested by the mesh at the terrace outlet and to prevent contamination by ensuring that

the runoff from the first 10-20 minutes of rainfall is flushed off.

No sewage or wastewater would be admitted into the system. No wastewater from areas likely

to have oil, grease, or other pollutants has been connected to the system.

Calculations for storm water load:

Roof-top area = Ground Coverage = 12,899.45m2

Green Area = 9517 m2

Paved Area = Total plot area – (Roof top area + Green Area)

= 32,512.44- (12899.45+ 9517) = 10095.99m2

Runoff Load

Roof-top Area = 12899.45 ×0.045 × 0.80

= 464.38 m3/hr

Green Area = 9517 × 0.045× 0.1

= 42.83m3/hr

Paved Area = 10095.99× 0.045× 0.7

= 318.02m3/hr

Taking 15 minutes retention time-Total volume of storm water

For Roof –top-Area = 464.38/4

= 116.09 m3



Taking the effective Dia. and depth of a Recharge pit 3 m and 4 m respectively, Volume of a single

Recharge pit = πr2h =3.14 x 1.5 x 1.5 x 4 = 28.26 m3

Hence No. of pits required = 116.09 /28.26 = 4.10 pits. ~ 4 pits.

For Green Area = 42.83/4

= 10.72 m3



Hence No. of pits required = 10.72 /28.26 = 0.37 pit. ~ 1 pit.

For Paved Area = 318.02/4

= 79.5 m3



Hence No. of pits required = 79.5 /28.26 = 2.81 pits. ~ 3 pits.

Total No. of pits required/proposed= 8

Therefore, a total of 8 Rain Water Harvesting pits are proposed within the project premises for

artificial ground water recharge.

4.6.2.3 Surface Water Quality

Impact: The sewage effluents generated from the Project will be collected through the sewer line

network provided in the premises of the project site, and treated in an onsite Sewage Treatment Plant

(STP) of capacity 627 KLD..

Mitigation Measures: As no impact is anticipated on the water bodies of the region, no mitigation

measures are suggested.



4.6.2.4 Ground Water Quality

Impact: The storm water from the site will be used for recharging groundwater resources after

adequate treatment of the storm water through oil, grease traps and filtration. The wastewater from the

site is proposed to be used for landscaping, flushing, HVAC cooling to achieve zero exit discharge.

Hence, no adverse impact is anticipated on the groundwater quality form the project.

Mitigation Measures: The project premises will be well maintained. Solid waste management

practices will be followed as per norms to prevent groundwater pollution.


Prediction of Impacts

Vehicular emissions and DG sets emission will be major sources of air pollution from building

construction projects. During the post construction phase, cars, scooter/motorcycle will be owned by

the population of such project. Ground Level Concentration of pollutants (as added by the project)

will depend upon the following:

Emission of pollutants from additional traffic on the roads due to the project.

Meteorological conditions.

Emission sources from D.G. Sets.

PM, NO2, SO2 and CO will be the main pollutants of primary concern released from traffic movement

and DG sets. Assuming that under cross wind condition perpendicular to the road, the dispersion of

vehicular emissions would be confined within limited distance from the road and concentration will

decrease with the increase in distance from road. It was anticipated that the contribution of vehicular

emissions from the exhaust in ambient air quality will be marginal as Pollution under Control (PUC)

Certified vehicles and branded make operated vehicle with low sulphur diesel will be used. Ground

Level Concentration (GLC) of pollutants is found to be well within the stipulated National Ambient

Air Quality Standards due to traffic movement and vehicles used inside the premises. DG sets will be

main source of Air Pollution in the project. CPCB/ MoEF approved USEPA dispersion model -

ISCST3 was used for prediction of impacts caused by DG sets. Stack & emission data was used as per

design value provided by standard make and stipulated standards. Other primary data used as input for



model were hourly meteorological data of Wind speed, direction, temperature, cloud amount and

mixing height. Mixing height used in the model was taken from secondary data source “Atlas of

Hourly Mixing Height Assimilative Capacity of Atmosphere in India published in 2008 by IMD,

Delhi”. Hourly meteorological monitored at site during study period data was compared with long

term data available from the nearest India Meteorological station or any other authorized source/Govt.

agencies.

In this project, 7 DG sets of total 11,000 kVA (3 x 2000 + 3 x 1500 + 1 x 500 kVA) capacity have

been proposed, for back up of electricity supply during power failure. This will cause emission of PM,

SO2, NO2 and CO in the Ambient Air Quality. In the project D.G. sets will be used only during power

failure and low sulphur diesel will be used as fuel to minimize SO2 emission. Therefore, incremental

load in the ambient air environment will be very low as given in the report. An adequate stack height

of D.G. sets will be provided as per the stipulated guidelines of Central Pollution Control Board

(CPCB)/ National Building Code Manual to facilitate proper dispersion of pollutants and to minimize

the impact on Ambient Air Quality under the influence of local meteorology.

Meteorology –Hourly Meteorological data of wind speed & direction, temperature, cloud amount and

rainfall were monitored at site for 1 month for the dispersion model. Wind rose (Figure - 4.1) was

prepared in sixteen directions as per standards. It was observed that westerly and northwesterly was

prevalent wind during the study period. Average wind speed was 2.78 m/sec and calm condition was

00.00% during 12th May-12th June 2016.



Figure 4.5: Wind Rose (Summer Season for 12th May to 12th June - 2016)

Model details and Frame work of Computation:

The predictions for air quality during operation phase were carried using CPCB/MoEF approved

“USEPA, Industrial Source Complex (Version - ISCST3)” Dispersion model developed by the US

Environmental Protection Agency (USEPA) for prediction of pollutants dispersion from single or

multiple point sources using emission and hourly meteorological data of the study period.

Assumption used in the model was as follows:



The plume rise is limited to that of the mixing layer as published by IMD in the Catalogue of

Atlas of Mixing Heights in India for the site

Stack down-wash is not considered.

Flat terrain is used for computations;

It is assumed that the pollutants do not undergo any physico-chemical transformation.

Chemical and scavenging process occurred in the atmosphere in the pollutants released at the

stack exit is not considered.

Prediction is based on single/multiplepoint sources, pollution released at stack exit and

dispersed on the ground under influence of local meteorological conditions during the season.

ISCST3 dispersion model was used to predict GLC caused by a single point source (4 stacks) at each

receptor of 40 m x 40 m of grid network covering total area of 2000 m x 2000m around the proposed

source with stack & emission values and 1-hourly meteorological data. It was observed that SO2,

NO2, Co and PM were significant pollutants released from the fuel of the D.G. sets. Emission of PM,

CO and SO2 were found insignificant with low values compared to NO2. In this project, NO2 was the

worst affected pollutant released into the atmosphere (Table 4.5) with high emission value.

Discussion of Results

ISCST3 - Dispersion model was used to predict GLC of all pollutants; SO2, NO2, CO and PM with

stack & emission and hourly meteorological data. 24-hours average maximum Incremental GLC of

NO2 was to be 3.62 µg/m3occurred at (2000m,00m), East from the DG sets fitted with 85 m

chimney.It was found that GLC of NO2 was less than the permissible limit of 80µg/m3 (as per CPCB

guidelines) under worst meteorological condition (Table 4.6) with meteorological data monitored on

4th June 2016.

Spatial distribution of NO2 is shown in Isopleth Figure 4.2. It was observed that GLC closed to the

proposed source will be not significant. 24-h maximum incremental GLC was 3.62 µg/m3 occurred at

the distance 2000 m, East of the project site.

Conclusion

Maximum Incremental GLC of NO2 is 3.62 µg/m3 due to DG sets in the Commercial project. High to

moderate wind speed and minimum stack height of 85 m facilitates dispersion at the distance of 2000

m east under the influence of local meteorology. Low GLC of pollutants was predicted due to high

Stack height of 85 m fitted with DG sets. Predicted GLC of all pollutants are given in Table 4.7 as

below:

Mitigation Measures: The project proponent will develop a green belt inside the premises of the

project site and along the internal road, which will work as barrier for the movement of pollutants and

help in pollution control.


Impact: The main sources of noise from the project are running of D.G. Sets and vehicular traffic.

D.G. Sets will provide emergency electricity supply during power failure. This will be intermittent and

for short durations. The vehicles playing within the site will be mainly of the residents and are hence

not expected to cause unnecessary noise. Hence, during this phase, no major impact on noise

environment is anticipated.

Mitigation Measures:

During the construction stage, expected noise levels shall be in the range of 80-85 dB (A) which will

decrease with increase in distance as per the Inverse Square Law. Considering that the project site is

away from populated area, it would not have any adverse effect outside the development area.

Administrative as well as engineering control of noise will be implemented. Isolation of noise

generation sources and temporal differentiation of noise generating activities will ensure minimum

noise at receiver’s end. To prevent any occupational hazard, ear muff / ear plug shall be given to the

workers working around or operating plant and machinery emitting high noise levels. Use of such

plant or machinery shall not be allowed during night hour. Careful planning of machinery operation

and scheduling of operations shall be done to minimise such impact.

4.6.5 Terrestrial Ecology

Impact: The project proposes 9517 m2 of green area that will be planted with local species with

aesthetic appeal that will attract local bird and insect species. As against the existing barren stretch of

land, the project will add to the greenery and beauty of the region.



Mitigation Measures: Various kinds of plantation such as curtain, avenue and ornamental plantation

and lawns will be started during the construction phase itself and maintained during the operation

phase. Open space and Parks will be fenced through the grasses and ornamental plants. Local and low

water demanding plants that will also be effective as sinks for various pollutants and attract birds will

be grown in the site that will contribute in positive to the local ecology.

4.6.6 Socio-economic Impact

Impact: During operational phase of the project, more than 8000 persons will get employment

opportunities as staff for management, maintenance and security. As an estimate, during post

construction phase, more than 300 persons will get marginal employment opportunities from the

residents of Project who would work as domestic helpers. This will help in improving the quality of

life of economically weaker sections of the local area.

Mitigation Measures: To further improve the socio-economic conditions of the area, it may be

proposed to employ mainly local people as workers. Much of the maintenance arrangements may also

be made with local companies and purchase of new parts from the local market.

4.6.7 Transport Linkage and Traffic

Impact: The vehicle from the project will increase car and two wheeler traffic load along the road

during peak hours. However, since present load is lean, increase in traffic load may not lead to traffic

congestion problem.

Mitigation Measures: As per the conceptual plan, the entrance to the project site is proposed along

the road. The available width of road provided shall have sufficient merging space for the vehicles

while meeting the road.

4.6.8 Energy Resources

Impact: During the operation phase of the project, electricity supply will be provided by State

Electricity Board. Mitigation Measures: To promote energy conservation, it is proposed to provide

the buildings with efficient energy consuming fixtures and maximize availability of natural light.




CHAPTER 5: ANALYSIS OF ALTERNATIVES

5.1 INTRODUCTION

This chapter discusses the assessment of various options that may be available for different

components of the project in terms of environmental suitability. Lately, there are a number of

options available for the use of building materials, means of energy conservation and methods of

transportation. The various applicable options are thus evaluated for their suitability to project

and environment.

5.2 BUILDING MATERIALS

The choice of building materials plays an important role in terms of energy efficiency of the

building. The manufacture of building materials should also be assessed to ensure the use of

environment friendly and recycled/ recyclable construction materials.

5.2.1 Wall

Conventionally, sun burnt clay bricks are cemented in the construction of walls. The strength of

these construction materials cannot be compromised which will otherwise pose a threat to the life

and property of the occupants. However, presently, materials with similar properties are easily

available that are made of waste products, thereby reducing the waste burden and conserving

natural resources. Thus, the project proposes the use of the following for walls:

Brick and block products with waste and recycled contents such as fly ash (15 to 35%),

blast furnace slag (20 to 25%), sewage sludge, waste wood fibre etc.

Fly ash based lightweight aerated concrete blocks – flyash being a waste product of

thermal power plant poses the challenge of disposal. Hazardous in powder form, it is rendered

harmless when moulded as bricks. Fly ash-based lightweight aerated concrete

blocks are manufactured for walling and roofing purposes by mixing fly ash, quick lime, or

cement and gypsum with a foaming agent like aluminum powder

Fal-G products – are manufactured by use of two waste products being fly ash, calcined

gypsum (a byproduct of phosphogypsum or natural gypsum) along with lime.




Perforated bricks

Materials proposed for use in the wall openings such as doors and windows include:

Precast thin lintels, use of Ferrocement-sunshade cum lintel etc.

Renewable timber

Steel manufactured from recycled content

Aluminum manufactured from verified recycled content

Saw dust based doors and window frames

Ferrocement shutters, PVC doors and windows, Rice husk boards, Natural fibre-

reinforced

Polymer composite door panels

The finishing for the openings will be by the use of Fly ash, Ceramic tiles, Terrazzo

floors.

5.2.2 Roof

The conventional material used for roofing is RCC, as it is suitable for longer spans. The

constituents of RCC, i.e. cement, sand, aggregate and steel are energy intensive materials and

high embodied energy content.

Alternately, it is proposed to use lightweight synthetic aggregates such as fly ash based

aggregates, which is suitable for manufacture of brick, blocks, and is good substitute for clinker

and natural aggregates. When pre-cast/aerated cellular concrete walling blocks and roofing slabs

are used in multi- storied structures, they reduce the weight, resulting in a more economical

design. They have high rating to fire resistance and provide better insulation and thus improved

energy efficiency. These are manufactured by the aerated cellular concrete manufacturing

process.

5.2.3 Insulation of Roof and wall

Roof will be insulated with required thickness with PUF or equivalent to achieve Roof U

Value. Window Glass will be double reflective type to minimize energy consumption. Roof/wall

insulation will be scope of Civil works.




5.2.4 Superstructure

Structural frame of building comprises of footing, columns, beams and lintels, over which the

envelope of building is supported. A variety of metals are used in buildings. The major building

material used structurally is steel. Steel has a high-embodied energy and recyclable content, as

well as scrap value. Aluminum forms the second most common material used for roofing sheets,

window frames, and cladding systems, which has the highest recyclable content. Hence, bulk of

the metal needs for the building will be met by steel and aluminum.

Problem with RCC. The choice of cement will be:

Use of fly ash and/or blast furnace slag concrete: The amount of cement used in

concrete can be reduced by replacing a portion of the cement with coal fly ash (waste material

from coal burning power plants) and/or GGBF (ground granulated blast furnace) slag in

conventional mixes.




Recycled aggregates: Recycled aggregates include crushed concrete, brick, glass, or

other masonry waste can also be used in conventional mixes

Lightweight concrete: Aluminum powder when added to lime reacts and form hydrogen

bubbles, and a lightweight cementation material is formed which could be used in conventional

mixes.

5.2.5 Roads and open spaces

Roads and open spaces consist of compound walls, grills, roads, sidewalks, parking lots, drains,

curbs, landscaped areas, street furniture, tree covers, and flowerbeds.

In line with environment friendly design it is proposed to provide:

Permeable paving- Permeable (porous) paving will be provided to control surface water

runoff by allowing storm water to infiltrate the soil and return to the ground water. The traffic

areas will however continue to be impermeable.

Gravel/crusher fines - Loose aggregate materials from masonry wastes will be used to

cover pedestrian surfaces.

Use of grass pavers on the road, parking and pedestrian areas to reduce the heat island

effect.

Use of steel in fencing, grills, tree covers, and benches and even in streetlights will be

replaced by bamboo in the parks and green landscaped areas.

5.2.6 Material of construction for plumbing and sanitary works




5.3 NATURAL HAZARD PRONE AREAS

The project site falls in Seismic Zone- IV. Special attention has been given to the structural

design of foundation, elements of masonry, timber, plain concrete, reinforced concrete, pre-

stressed concrete, and structural steel. All applicable guidelines (IS Codes) will be followed in

this regard to ensure structural safety of the building.




5.4 ENVIRONMENT FRIENDLY BUILDING

As a responsible corporate, M/s. WTC NOIDA Development Company Pvt. Ltd. has proposed

to design and construct the Commercial Project in line with the requirements of Environment

friendly building. Care will be taken to achieve energy efficiency, water consciousness, etc. This

will be achieved through:

a. Minimal disturbance to landscape and site condition

The project aims to integrate the new development with the local existing surroundings. Efforts

are made to minimize on-site tree cutting by careful and detailed layout planning. Tree felling

will be undertaken only after receiving requisite permissions and under strict supervision. The

original landscape of the site has also been integrated with the design of the Commercial Project

such that there is no alteration in the site topography.

b. Resource Conservation and Environmental Friendly Building Materials

To reduce the ecological footprint of the development, use of recycled material for construction

and conserving natural resources is of primary importance. In this light, the use of recyclable

building materials has been proposed for various building materials. It is also proposed to reuse

building components, minimization of construction wastes etc.

The project is also committed towards conservation of water. This includes use of treated water,

rainwater harvesting, provision of low water flow fixtures and raising awareness on means of

water conservation.

c. Efficient use of Water and Water Recycling

The need for water conservation in the face of impending water crisis cannot be overemphasized.

The project will follow a three pronged management for water resource viz: water resource

development, minimize use of water and recycle water generated within the site.

Rainwater harvesting across the entire project area is proposed to recharge groundwater. A

detailed storm water drainage system and water harvesting procedures are proposed to achieve

this.




The water demand is proposed to be brought down by the use of water efficient fixtures,

implement best management practices for water in both Commercial Project and horticultural

activities. An important means for achieving this is spreading awareness to the occupants for

generating water conservation awareness.

To reduce the freshwater demand of the project, waste water from the project will be treated in

an onsite STP and recycled treated effluent will be reused for landscaping, flushing, HVAC.

d. Use of Energy Efficient design and Eco-Friendly Equipment

The commercial project will be designed such that there is optimal solar energy utilization,

especially for natural light availability. Shading will be provided on sides that will otherwise

reduce the energy efficiency of the building. Energy conservation will be one of the focuses

during the planning, development, construction and operation stages.

Use of Renewable Energy

The electrical supply is largely dependent on thermal power plants that are largely responsible

for accelerating the phenomenon of global warming and consumption of limited natural

resources. It is of paramount importance to shift focus on other renewable sources of energy to

achieve sustainable development in the energy sector. The project area in S.A.S Nagar receives

adequate hours and intensity of sunlight for effective solar energy generation. Taking full

cognizance of the availability of natural sunlight and technology, the project proposes the use of

solar energy to reduce the power demand of the project.

Solar energy will be used for the use of renewable energy.

e. Indoor Air Quality for Human Safety and Comfort

To provide the occupants with a safe building is the primary responsibility of a developer. Indoor

pollution sources that release gases or particles into the air are the primary cause of indoor air

quality problems in homes. Inadequate ventilation can increase indoor pollutant levels by not

bringing in enough outdoor air to dilute emissions from indoor sources and by not carrying

indoor air pollutants out of the home. High temperature and humidity levels can also increase

concentration of some pollutants. Likewise, it is proposed to use all user friendly building

materials such as:




i. The buildings will be painted with low VOC, ammonia free paints.

ii. Asbestos will not be used.

iii. Adequate ventilation will be provided in each unit and floor

iv. Adequate openings for sunlight to enter the building, thereby reducing chances of microbial

growth.

v. All building maintenance and cleaning materials will be kept in an isolated and well

ventilated room with restricted entry.

f. Effective Controls and Management Systems

It is proposed to establish a Management System that will comprise modern equipment as well as

an efficient team of maintenance staff.

i. Each tower as well as common area will be provided with fire alarm as well as water

sprinklers. All essential services such as lifts and water supply will be provided with power

back up.

ii. A security system for the entire ‘World Trade Centre’ Commercial project, will be provided

comprising intercom facility, closed circuit camera to the entrance and round-the-clock

manning.

iii. . The staffs’ vehicles will be provided with identification stickers while visitors’ vehicles

will be monitored through security guards at the entrances.

The project further proposes extensive green areas as avenues, parks and roadside plantations.

The plants not only serve various direct environmental facilities, but also have indirect positive

environmental impacts such as reduction in overall energy use in buildings.

5.5 COMMUNITY ISSUES

Apart from the site occupants, all efforts will be made to ensure that the exiting neighborhood is

not adversely affected by the project.

5.6 ENERGY CONSERVATION

To achieve conservation of energy, appropriate design of a building is of paramount importance.

Accordingly, it is proposed to incorporate the guidelines of Energy conservation Building Code,

2005 for the structures of the Commercial Project.




Effective measures have been incorporated to minimize the energy consumption in following

manners:

• Use of LED lamps instead of GLS lamps commercial project.

• Use of LED instead of GLS lamps for Common area.

• T5 lamps are used instead of Normal Fluorescent lamps in Basements

• Using electronic ballast for Discharge Lamps

• Hot water system

Hot water for domestic use for Service Apartment will be provided through Heat Pumps.

Hot water temperature of 60C (140F) will be maintained to avoid grow of legionnaires

disease bacteria.

Solar Water Heating System will be provided to meet the Hot water requirement for Food

Court/Restaurant/Food Shop and pre heating for hot water system for Hotel/Service

apartment proposed.

It has been proposed 16.56 % energy savings to be achieved in the project

Table 5.1: Energy savings calculation




5.7 TRANSPORTATION

A well planned road network is proposed within the project premises as per NBC norms.

Adequate parking will be provided during construction phase to ensure that all heavy vehicles

visiting the site are parked within the site. There will be no parking on the public roads. The

movement of the vehicles will also be scheduled such that the peak hours are avoided.

In the operation phase, entry and exits will be from separate gates to minimize disturbance to the

approach roads to the project site. To avoid congestion of the approach roads, space will be

provided for vehicles waiting checking. Adequate parking is proposed as per norms to ensure

there is no parking along the roads.

In absence of detailed model split data for the Chandigarh city, collateral data from the

Chandigarh Master Plan- 2030 and RITES Comprehensive Traffic and Transportation plan were

considered in estimating the traffic patterns for the project.

Chandigarh Master Plan has recorded the present composition of traffic on roads at 80%

constituting of cars and two wheelers and also indicated that the vehicle ownership is high at 86

% of households have car, two-wheeler or both.

Comprehensive Traffic and Transportation Plan of Chandigarh prepared by the RITES assumed

that the mass transport for the city would cater to the 54% of the total traffic trips that generated

for the year 2014 and that it would increase its share for the future years. Having accepted the

split of mass transport as 54% the balance 46% of the trips obviously shared by the Cars, Two

Wheelers and Taxis/ Cabs.

Having considering the collateral inputs from the above two traffic connected reports the model

One of the theme of integrated land use planning is that the traffic on roads would be reduced if some of the residential requirement is met within the complex. Assuming that the occupants of the hotel/serviced units work in the offices then the traffic generated would get reduced. It is estimated that about 10% of trips from the offices category would be discounted on this principle. Table 5.5 shows the final traffic generating trips after discounting.

Table shows the PM peak generation as per the gross floor areas of the project. In this calculation Multiplex traffic is included as it is in the evening period. The evening peak hour traffic is usually more than the morning and as such the aforesaid projection is in tune with the accepted procedure. The traffic estimation is therefore crosschecked and found to be satisfactory.

Traffic Carrying Capacity of the Access road to the project.

As the access road is said to be 50 ft or 15 m wide road its carriage width could be 3 lane

therefore it can carry the peak traffic load. Volume – Capacity ratio indicate a fairly clear state

of road performance against traffic flows on it. V-C categorizes the level of service ranging

from A to E from free flow to extent of congestion . The volumes in this case is 1478 pcus.




The capacity of the access road is 2000 pcus. The V/C ratio for the road is 0.739, . This

gives a level of service of B which is without congestion and graded to have free flow.

Surface movements and Entry& Exit .

As per the road configuration at the project there is least possibility of traffic entering from the

rear road. High proportion of traffic enter from the front arriving from all four sides of the

junction. About 1800 vehicles would be coming to enter in to the parking and drop off. The

traffic would enter the premises through the internal road between commercial complex and the

hotel. Almost 50% of it enter in to the basement and the other 50% go to MLCP. Therefore

entry will be from the front side.

It makes traffic flow hassle free if all the exits are proposed towards the rear side road. Therefore

the exit will be to the rear side road.

This arrangement will also avoid multiple check points.

The arrangement also makes the surface vehicular movement hassle free straight forward.

Entry and Exit Ramps.

Vehicular Loads on ramps :

Basement ramps

Subject to final figures of parking the basement to have 540 ECS of single stack parking and if

upgraded to double- stack parking it would increase to 1000ECS. Each ramp can discharge 500

units per hour. This is at highest possibility. Therefore two ramps are adequate.

MLCP ramps

Similarly MLCP parking figures for each level comes to 163 ECS. Total count would be 815

units as the ramps are on multi- levels the discharge capacity would be limited to about 400

units

However it require minor changes for vehicular ramps for basement and MLCP.

The following suggestions are made in view of circulation and capacity requirements 1. The present descending ramp of basement be converted in to two-lane ramp of width 8 mtr (

front side one)




2. Basement exit ramp from hotel side to remain as it is.

3. Another exit ramp for basement to rear side road would be better.

4. Ascending ramps for MLCP will be two-lane, up to third level and from third level to 5th level it

will be single with.

5. Entry point of ascending ramp will be from inside the building as was shown in earlier dwg as it

facilitates security check space as well as waiting space to enter in rush hours.

6. Descending ramps for MLCP will be one lane width down to 3rd level and from 3rd level to rear

side road level with two-lane width.

CHAPTER 7: ADDITIONAL STUDIES 7.0 INTRODUCTION

This chapter broadly looks at various aspects related to disaster management and resource

conservation.

7.1 RISK ASSESSMENT AND DISASTER MANAGEMENT PLAN

Proposed ‘World Trade Centre’ commercial project will encompass the lives of a large number

of people. It involves installation of various structures to meet the comfort and needs of its users

but may also serious threat to the occupants in case of an accident. It thus becomes necessary to

carry out a risk assessment and disaster management plan for the project.

7.1.1 Risk Hazard & its control measures

It is attempted to plan and construct the buildings following all safety norms. However, it is not

always possible to totally eliminate such eventualities and random failures of equipment or

human errors. An essential part of major hazard control has therefore, to be concerned with

mitigating the effects of such emergency and restoration of normalcy at the earliest. A detailed

table showing activities during construction and operation phase along with mitigation measures

are given in Table 7.1.

7.1.2 Emergency Response Plan (ERP)

The overall objective of an Emergency Response Plan (ERP) is to make use of the combined

resources at the site and outside services to achieve the following:

1. To localize the emergency and if possible eliminate it;

2. To minimize the effects of the accident on people and property;

3. Effect the rescue and medical treatment of casualties;

4. Safeguard other people;

5. Evacuate people to safe areas;

6. Informing and collaborating with statutory authorities;

7. Initially contain and ultimately bring the incident under control;

8. Preserve relevant records and equipment for the subsequent enquiry into the cause and

circumstances of the emergency;

9. Investigating and taking steps to prevent reoccurrence

The ERP is therefore related to identification of sources from which hazards can arise and the

maximum credible loss scenario that can take place in the concerned area. The plan takes into

account the maximum credible loss scenario - actions that can successfully mitigate the effects of

losses/ emergency need to be well planned so that they would require less effort and resources to

control and terminate emergencies, should the same occur.

Main hazards identified for the project include hazards pertaining to fires in buildings and fire in

diesel storage areas, earthquake and LPG leakage and an ERP pertaining to these is described in

the following section.

7.2 RESPONSE IN CASE OF EARTHQUAKE

Response Procedures for Occupants

If indoors:

1. Take cover under a piece of heavy furniture or against an inside wall and hold on.

2. Stay inside: The most dangerous thing to do during the shaking of an earthquake is to try to

leave the building because objects can fall on you.




If outdoors:

Move into the open, away from buildings, streetlights, and utility wires. Once in the open, stay

there until the shaking stops.

If in a moving vehicle:

Stop quickly and stay in the vehicle. Move to a clear area away from buildings, trees, overpasses,

or utility wires. Once the shaking has stopped, proceed with caution. Avoid bridges or ramps

that might have been damaged by the quake.

After the earth quake

1. After the earthquake be prepared for aftershocks.

2. Although smaller than the main shock, aftershocks cause additional damage and may bring

weakened structures down. Aftershocks can occur in the first hours, days, weeks, or even months

after the quake.

Help injured or trapped persons.

1. Give first aid where appropriate. Do not move seriously injured persons unless they are in

immediate danger of further injury. Call for help.

2. Remember to help those who may require special assistance--infants, the elderly, and people

with disabilities.

3. Stay out of damaged buildings.

4. Use the telephone only for emergency calls.

Response Procedure for Emergency Team

1. Formulate an Emergency Response Team for earthquake response.

Using the public address system, inform residents of response procedures discussed above.

2. Inform the necessary authorities for aid.

3. Ensure no person is stuck beneath any debris, in case of a structural failure.

4. Ensure that all occupants standing outside near the buildings are taken to open areas.

5. Ensure that the first aid ambulance and fire tender vehicles are summoned if necessary.

6. Inform the nearby hospitals if there are any injuries.

7. Check the utilities and storage tanks for any damage.




7.3 RESPONSE FOR LPG LEAKAGE

1. The affected area should be evacuated and cordoned off immediately

2. Initiate an Emergency Response Team for LPG leakage.

3. Shut down the main valves in the gas bank.

4. Ensure that only concerned personnel are present in the affected area and all other personnel

and visitors are moved to the nearest assembly points.

5. Rescue trapped personnel, also check if any personnel are unconscious in the area and

immediately move them outside and provide first aid. Ambulance should be summoned to take

injured personnel to the nearest hospital.

6. Personnel in the nearby buildings to close all doors and windows to prevent entry of the leaked

gas.

7. Source of leakage to be traced and isolated from all the other areas. And if required use

pedestal fans to bring down the gas concentration.

8. In case of a fire follow the instructions in case of fire.

7.4 RESPONSE IN CASE OF FIRE

1. Required response during in the event of a fire should be described in signs located in the

lobby.

2. On sighting a fire, it should be immediately informed to the environment manager

giving the exact location and type of fire in detail.

3. Initiate the Emergency Response Team for fires.

4. If the fire is small, engage in extinguishing the fire using the nearest fire extinguisher.

5. Guide the Emergency Response Team staff to the emergency assembly point.

6. The Emergency Response Team should immediately inform the nearest dispensary and

security force. If required a fire tender should be summoned.

7. The response team should immediately move to the point of fire and take all necessary steps to

stop the fire. If the fire is not controllable and spreads then the manager in charge should inform

the district authorities and call for external help.




8. The Emergency Response Team will provide immediate relief to the injured residents at the

scene of incident. Any injured persons should be evacuated on priority to the dispensary or one

of the nearest hospitals based on their condition.

Instructions for occupants

1. Get out of buildings as quickly and as safely as possible.

2. Use the stairs to escape. When evacuating, stay low to the ground.

3. If possible, cover mouth with a cloth to avoid inhaling smoke and gases.

4. Close doors in each room after escaping to delay the spread of the fire.

5. If in a room with a closed door.

6. If smoke is pouring in around the bottom of the door or if it feels hot, keep the door closed.

7. Open a window to escape or for fresh air while awaiting rescue.

8. If there is no smoke at the bottom or top and the door is not hot, then open the door slowly.

9. If there is too much smoke or fire in the hall, slam the door shut.

10. Stay out of damaged buildings.

11. Check that all wiring and utilities are safe.

A state of the art firefighting system is proposed for the project to prevent and control fire

outbreaks. The firefighting system will consist of portable fire extinguishers, hose reel, wet riser,

yard hydrant, automatic sprinkler system, and manual fire alarm system. The ‘World Trade

Centre’ Commercial project buildings will also be provided with automatic fire detection and

alarm system.

7.5 RESOURCE CONSERVATION

The project will lead to utilization of various natural resources. As an environmentally

responsible corporate, the developers endeavor to conserve these resources by judicious

management and recycling and strive to build up these resources where possible.

Limited withdrawal of groundwater: The water during operational phase will be supplied by

GMADA.

Reduced use of water: To further minimize the use of available freshwater, various low flow

fixtures may be provided such as Low flow flushing systems, sensor based fixtures, , tap

aerators. Awareness will also be spread amongst the residents on the following lines:




Timely detection and repair of all leakages;

Turning off tap while brushing teeth;

Avoiding use of running water while hand-washing;

Avoiding use of running water for releasing ice tray ahead of time from freezer;

Turning off the main valve of water while going outdoor;

Avoiding use of hose for washing floors; Use of broom may be preferred;

Watering of lawn or garden during the coolest part of the day (early morning or

late evening, hours) when temperature and wind speed are lowest. This reduces

losses due to evaporation.

Planting of native and/or drought tolerant grasses, ground covers, shrubs and

trees. Once fully grown, they need not to be watered frequently.

Avoiding over watering of lawns. Good rains eliminate the need for watering for

more than a week.

Setting sprinklers to water the lawn or garden only, not the street or sidewalk;

Avoiding installation or use of ornamental water features unless they recycle the

water and avoiding running them during drought or hot weather;

Installation of high-pressure, low-volume nozzles on spray washers;

Replacement of high-volume hoses with high-pressure, low-volume cleaning

systems;

Equipping spring loaded shutoff nozzles on hoses;

Installation of float-controlled valve on the make-up line, closing filling line

during operation, provision of surge tanks for each system avoid overflow;

Washing vehicles less often, or using commercial car wash that recycles water;

Treatment and Recycling: The wastewater generated from the sites will be treated in an on-site

Sewage Treatment Plant. This will enable the treated wastewater to be used for flushing and

landscaping thereby reducing the requirement of freshwater for these purposes.

Rainwater harvesting: The increased hard surface increases the runoff as compared to the

otherwise barren land. It is proposed to harvest this rainwater runoff that will recharge the




groundwater resource while reducing the burden of storm water management of the city and

eventually natural water bodies. Apart from the open spaces, it is proposed to harvest the roof top

rainwater. The storm water will be treated through an oil and grease trap and allowed to flow

through layers of sand and gravel for filtration prior to reaching the water table, to avoid any

possibility of groundwater contamination.

Construction materials: Various kinds of natural construction materials such as sand, gravel etc

will be used. It is proposed for prior estimation of required quantities of these materials and

procurement only as per requirement. This will also result in cost-efficiency. Excavated soil from

the project site will be used within the site to the extent feasible. Excess soil will be made

available to the construction sites, as per need.

Energy: To conserve the energy resources, good practices will be followed during the

construction phase such as turning off lights and equipments when not in use, ensuring fuel

efficiency of motors and vehicles through proper maintenance and minimal work at night. The

principles of energy conservation will also be embedded in the buildings through use of energy

efficient fixtures, maximum availability of natural light and use of solar energy for street

lighting.

7.6 RESETTLEMENT AND REHABILITATION

The project will not result in displacement of any local population and hence, does not require a

resettlement and rehabilitation.

7.7 SOCIAL IMPACT ASSESSMENT

Social impact assessment has been discussed in Chapter 3 and Chapter 4.




CHAPTER 8: PROJECT BENEFITS

medical aids, and aid in children’s education.




The project will provide employment opportunities to approx. 8000 persons during the operation

phase.




CHAPTER 9: ENVIRONMENTAL MANAGEMENT PLAN

9.1 INTRODUCTION

Identification and prediction of impacts further needs to suggest the mitigation measures

which would play a vital role in prevention of environmental degradation during construction

and operational phase of the proposed ‘World Trade Centre’ commercial project. Therefore,

EMP forms an imperative part of EIA process.

The Environmental Management plan is a site specific plan developed to ensure that the

project is implemented in an environmentally sustainable manner where all contractors and

subcontractors, including consultants if any, understand the potential environmental risks

arising from the project and take appropriate actions to minimize those risks. EMP also

ensures that the project implementation is carried out in accordance with the planned design

and by taking appropriate mitigates actions to reduce adverse environmental impacts during

project’s life cycle.

The project will create certain inevitable impacts, mainly during construction phase, although

within permissible limits as mentioned in Chapter 4 and can be reduced significantly with the

help of effective implementation of a well-designed EMP. The potential environmental

impacts, which need to be regulated, are mentioned below:

Air pollution due to the emission of particulate matter and gaseous pollutants from

operation of D.G. Sets during power failure and vehicular movement;

Noise pollution due to various noise generating equipment as well as vehicular

movement;

Water resource management to ensure continuous water supply.

Wastewater generation from sanitary/domestic activities; and

Generation of municipal solid wastes from residences, maintenance of roads, parks,

common areas including constructional, electrical and plumbing wastes.

Energy conservation methods

Maintenance of Building Management Systems and emergency aids.




To ensure better environment in & around the project site, effective EMP is developed

separately for construction and operational phase.

9.2 ENVIRONMENTAL MANAGEMENT STRATEGIES

Strategy for environmental management in construction work should be based on three-

pronged approach comprising of:

Pollution prevention.

Pollution control.

Protection of pollution recipients.

9.2.1 Topography and Physiography

During the development, construction and operation phase of the project, no significant

impact is anticipated on local or regional topography and Physiography; hence no

management plan is required. It is however proposed to carry out extensive turfing with local

species apart from proposed plantations and greens.

9.2.2 Soil

Development & Construction Phase

During the construction phase, various kinds of wastes are generated that will be disposed in

varied ways. The following measures will be taken to prevent soil contamination at site and

ensure waste management:

Vegetation and top soil management:

Plantation as proposed shall be started at the earliest.

The top soil will be stripped from constructional areas and stockpiled for later reuse in

landscaping.

Promote use of organic fertilizers.

Construction of erosion prevention troughs, as deemed necessary.

To prevent the erosion of excavated loose soil produced as a result of excavation, site

preparation activities and excavation work would be undertaken during dry season after

monsoon is over.




Construction Debris:

Fuel and oil would be stored in cement lined storage yard and handled carefully to

prevent soil contamination through leakage or spillage.

All metal, paper, plastic wastes, debris and cuttings would be collected from site as

soon as particular construction activity is over.

During construction of flexible pavement, bitumen wastes will be collected (if any)

and disposed in environmentally sound manner.

The number, frequency and area of movement of heavy machinery will also be

restricted.

Recycling of construction wastes into aggregates for use in the project site.

Used oil from DG Sets should be stored in HDPE drums in isolated covered facility

and disposed-off as per the Hazardous Wastes (Management & Handling) Rules, 1989.

Wastes from the labour camps will be collected and disposed as per the existing

practices in the site.

Operation Phase

To prevent soil contamination at site, the most important aspect is to manage the solid wastes

that will be generated during the operation phase. The Environmental Management Plan for

the solid waste focuses on three major components during the life cycle of the waste

management system i.e. collection, transportation, and treatment or disposal.

Collection and segregation of wastes

Solid waste generated from project would be collected and segregated into

decomposable, recyclable and inert wastes.

Decomposable wastes will be decomposed and converted to manure to be used for

horticulture.

Recyclable waste would be sold to vendors.

Inert waste which comprises a very small amount of the total solid waste generated

would be temporarily stored within the project premises.

Waste bins would be placed at the strategic locations such as inter section of internal

roads, parks, common places, etc.




To minimize littering and odors, waste will be stored in well-designed containers/

bins that will be located at strategic locations to minimize disturbance in traffic flow.

Care would be taken such that the collection vehicles are well maintained and

generate minimum noise and emissions. During transportation of the waste, it will be covered

to avoid littering.

Hazardous & bio medical Waste will be handled as per Hazardous Waste & Bio

Medical Waste Management Act.

Transportation

Only the non-recyclable and non-biodegradable waste will be transported to the designated

disposal site. The segregation, transportation and disposal of wastes will be done through a

local authorized agency that will take care of the solid waste management of the project.

Figure 9.1 Waste Management Flow Diagram (Operation Phase)

Disposal With regards to the disposal/ treatment of waste, the project proponent will take the

services of a local authorized agency.




9.2.3 Hydrology

9.2.3.1 Surface water Hydrology


To ensure adequate passage of the storm water as per the regional drainage pattern, water

channels will be provided. It is also suggested to avoid excavation during monsoons.

Chemicals such as paints, varnishes and oil/ grease will be stored under covered and

cemented areas. Wash offs containing these chemicals will be drained into impervious trains

for disposal as hazardous wastes.

Operation Phase

It is proposed to provide rainwater harvesting across the project site. The roof tops of

buildings will also be connected to the rainwater collection system. This will not only reduce

the pressure of storm water management system of the city and eventually the water bodies

but also recharge groundwater.

9.2.3.2 Ground water Hydrology


The water requirement during the construction period will be from private water tanker. The

following are also proposed to further reduce the demand of freshwater:

Curing water will be sprayed on concrete structures and free flow of water not

allowed.

After liberal curing on the first day, all concrete structures will be painted with curing

chemical to save water to stop daily water curing hence save water.

Concrete structures will be covered with thick cloth/gunny bags and then water

sprayed on them to avoid water rebound and ensure sustained and complete curing.

Pools will be made using cement and sand mortar to avoid water flowing away from

the flat surface while curing.

Water ponding will be done on all sunken slabs. This will also highlight the

importance of having an impervious formwork.




Operation Phase

It is proposed to conserve groundwater resources through the combined means of water

resource development, minimized water consumption and reuse of treated water to reduce

freshwater demand.

Water Resource Development

Keeping in view the rainfall, storm water drainage system will be developed to carry the

runoff.

The storm water disposal system for the premises shall be self-sufficient to avoid any

collection/stagnation and flooding of water. The amount of storm water run-off depends upon

many factors such as intensity and duration of precipitation, characteristics of the tributary

area and the time required for such flow to reach the drains. The drains shall be located near

the carriage way along either side of the roads. Taking the advantage of road camber, the

rainfall run off from roads shall flow towards the drains. Storm water from various buildings

shall be connected to adjacent drain by a pipe through catch basins. 8 Rainwater harvesting

pits are proposed for recharging the ground water level of the area. Rain water harvesting

details are given in Chapter 2.

Storm water management system

Since the storm water on site will be harvested for ground water recharge, proper

management of this resource is necessary to prevent contamination. Hence, regular inspection

and cleaning of storm drains shall be carried out. Use of fertilizers and pesticides will be

avoided prior to monsoons. Clarifiers or oil/ water separators shall also be installed in all the

parking areas.

Minimal Water Consumption

To reduce the water consumption, awareness along the following lines will be spread

amongst the management and maintenance team:

Installation of water meters conforming to ISO standards at inlet and outlet point of

water supply.




To further lower the water consumption, options of low flow flushing systems, sensor

based fixtures, , and tap aerators, etc will be explored.

Leak detection

Use of low-volume, low-angle sprinklers for lawn areas.

The message of water conservation will be spread amongst the residents through awareness

campaigns and pamphlets. Following tips shall be provided to the residents for conserving

water.

Timely detection and repair of all leakages;

Turning off tap while brushing teeth;

Use of mug rather than running water for shaving;

Avoiding/minimizing use of shower/bath tub in bathroom;

Turning off faucets while soaping and rinsing clothes;

Using automatic washing machine only when it is fully loaded;

Avoiding use of running water while hand-washing;

Avoiding use of running water for releasing ice tray ahead of time from freezer;

Turning off the main valve of water while going outdoor;

Avoiding use of hose for washing floors; Use of broom may be preferred;

Watering of lawn or garden during the coolest part of the day (early morning or late

evening, hours) when temperature and wind speed are lowest. This reduces losses due to

evaporation.

Planting of native and/or drought tolerant grasses, ground covers, shrubs and trees.

Once fully grown, they need not to be watered frequently.

Avoiding over watering of lawns. Good rains eliminate the need for watering for more

than a week.

Setting sprinklers to water the lawn or garden only, not the street or sidewalk;

Avoiding installation or use of ornamental water features unless they recycle the

water and avoiding running them during drought or hot weather;

Installation of high-pressure, low-volume nozzles on spray washers;

Replacement of high-volume hoses with high-pressure, low-volume cleaning systems;

Equipping spring loaded shutoff nozzles on hoses;




Installation of float-controlled valve on the make-up line, closing filling line during

operation, provision of surge tanks for each system avoid overflow;

Washing vehicles less often, or using commercial car wash that recycles water.

Re-use of treated wastewater

Treated wastewater from the site will be recycled for landscaping, flushing and HVAC/DG

Set cooling to further reduce demand of freshwater resources. This will be achieved by

treating the wastewater generated from the project in an onsite Sewage Treatment Plant of

(627 KLD). The details of STP are given in Chapter 2.

Surface water Quality


To mitigate the impacts of soil erosion during first rain and generation of wastewater from

construction labour camps, the following measures are proposed;

Excavation during dry season and proper management of excavated soils,

Clearing all debris from site as soon as construction is over,

Provision of proper hutment and toilet facilities for construction labour,

Proper disposal of wastewater generated at site.

Ground water Quality

Development and Construction Phase

To ensure against any groundwater pollution through leaching of soil, solid waste

management plan ensuring timely collection of wastes will be followed. The collected wastes

will be stored at designated area and disposed as per the standard procedures in line with the

statutory requirements.

Operation Phase

The ground water pollution can arise from improper waste handling or by recharge of

groundwater through contaminated storm water. A well planned solid waste management as

discussed in chapter 2 is proposed for the operation phase that will ensure against any

chances of soil or groundwater pollution on this account.




Storm water collects dirt and garbage along its flow. Contamination of this water with spilled

oil/ grease is especially of concern when recharging is proposed. Hence, preliminary

treatment for oil, grease and filtration through layers of sand and gravel is proposed prior to

recharge of the groundwater.

Landscaping water enters the soil and finally the groundwater. It is thus of utmost importance

that only clean water is used for horticulture purposes. The water from the households will

contain significant amounts of detergent and soap that is undesirable for plants, soil and in

groundwater. Hence, it is proposed to treat wastewater from the sites up to tertiary level, and

be used for landscaping only thereafter regular monitoring of treated wastewater shall be

carried out to ensure that all parameters are within acceptable levels.

9.2.4 Air Quality


The construction phase of the project will continue for about 5-6 years. It will cause

marginal, temporary impact on ambient air quality from constructional activities, unloading

of construction materials, cement, soil and vehicular movement etc. The main pollutant of

concern is PM 2.5& PM 10 (dust). Likewise, following mitigation measures will be adopted

during this phase to mitigate the impacts on ambient air:

Loading and unloading of cement and other material in covered shed.

Providing dust suppression system in unloading area (as per requirement).

Developing avenue and curtain plantation on the internal roads and peripheral

plantation around the site to protect the movement of dust and other pollutants.

Cover scaffolding, hosing down road surfaces and cleaning of vehicles.

On-Road- Inspection for black smoke generating machinery.

Vehicles having pollution under control certificate will be allowed to ply.

Use of covering sheets for trucks to prevent dust dispersion from the trucks.

Reducing the speed of a vehicle to 20 km/hr to reduce emissions on site.

All material storages will be adequately covered and contained.

Training to the workers to reduce idling time of machines that otherwise tends to

produce hydrocarbons ad carbon monoxide.

Best practices for maintenance and repair of all machineries and equipment.




Operation Phase

During the operation phase, following measures will be adopted for pollution control:

Adequate stack height for DG Sets

Traffic pollution management

Plantation development

DG Set: The running of DG sets will result in emission of various pollutants. To achieve

adequate natural dispersion, adequate stack height will be provided as per guidelines of

Central Pollution Control Board (CPCB) for 11,000 kVA capacity DG sets.

Traffic pollution management: Internal roads would be maintained in good conditions to

control the dust emissions. Awareness will be raised amongst the residents for use of low

sulphur fuel.

Plantation development: Vegetation is an effective means for controlling air pollution due

its dual action of acting as a barrier between the source of emission and receptors and also as

a sink for various pollutants. It is proposed to develop plantation of species effective in

absorption of expected pollutants at site, along the internal roads and on the periphery of the

project site. Suggested species for plantation are:

Acacia nilotica (Babul)

Mangifera indica (Mango)

Dalbergia sisoo (Shisham)

Ficus religiosa (Pipal)

Ficus glomerata (Goolar)

9.2.5 Noise Levels


During the construction phase, some noise will be generated through the operation of

construction machines, excavators, DG set, etc. Following measures would be taken; into

consideration to mitigate the noise at construction site:

Use of well-maintained equipment fitted with silencers and providing noise shields

near the heavy construction operations




Acoustic enclosures would be provide to DG sets at the construction site,

Earmuff and other protection devices shall be provided to laborers working in high

noise generating machines.

High noise activities shall be carried out during daytime.

Operation Phase

The main sources of noise during this phase are the intermittent use of DG Sets and traffic.

The principles of noise emission control and screening are proposed for the two different

scenarios of noise generation.

Noise emission control

All D.G. Sets will be provided with acoustic enclosures ensuring 25 dB (A) insertion loss or

for meeting the ambient noise standards whichever is higher as per CPCB norms. It will be

ensured that the manufacturer provides acoustic enclosures as an integral part with Diesel

Generator Sets.

Barriers

Trees having thick and fleshy leaves with flexible petioles having capacity to withstand

vibration are suitable. Heavier branches and trunk of the trees also deflect or refract the sound

waves. The following species are proposed to be used in a greenbelt of the project.

Acacia nilotica (Babul)

Dalbergia sisoo (Shisham)

Ficus religiosa (Pipal)

9.2.6 Biological Environment

Development and construction phase

During the development, construction and operation phase, no tree will be cut and therefore

no impact is anticipated on terrestrial ecology. Site clearing shall be carried out strictly as per

plan. Workers shall be advised against cutting, uprooting, coppicing of trees or small trees

present in and around the project site for cooking. Workers shall also be discouraged from

wandering in nearby areas with plantation or dense vegetation.




Further, peripheral plantation along the internal roads of project site will be developed during

the construction phase itself that will act as a curtain to restrict the movement of pollutants

from either side of the project and improve site aesthetics.

Operation phase

During the operation phase, peripheral plantation will be developed along with organized

green spaces. Ornamental plant species and grasses will be planted in open space within the

premises. Green area measures 9517 m2. Proposed list of species for plantation is as follows:

9.2.7 Demographic and Socio-Economic Environment


During the development and construction phase of the project, more than 200 skilled,

semiskilled and unskilled workers will get direct and indirect employment opportunities

which will have beneficial impact on the socio-economic conditions of the area.

Following suggestions are given to strengthen the beneficial impacts on the socio-economic

investment strategy for the communities around the project. The project seeks to increase the

benefits to the local population and contribute towards meeting community’s expectation of

benefits from the project.

Some of the concerns raised by local people relate directly to the project. Concerns and

aspirations not directly related to the project were also solicited so as to identify areas that

could be addressed through socially responsible initiatives and interventions. These were:

a) Demand for employment opportunities.

b) Infrastructure development

The proposed strategy envisages addressing the wider goal of sharing benefits with the local

community. The following activities would be undertaken:

Income Generation Opportunity for local community

The local people will be given preference, although they will be recruited on their individual

merit. Tender specification for operation services will include favorable employment

opportunities towards the local population. The main principles of employment are outlined

below:




Employment strategy will provide for preferential employment during operation

phase.

General recruitment procedures will be transparent, public and open to all.

Recruitment procedures will be publicized at locally prominent locations in advance.

There will be no discrimination on basis of gender, caste or other factors.

CHAPTER 10: SUMMARY AND CONCLUSION

10.1 PROJECT BACKGROUND

M/s. WTC NOIDA Development Company Pvt. Ltd. intends to develop ‘World Trade Centre’ a

Commercial project located at Plot No. 2, Block-D, Aerocity, S.A.S Nagar, Mohali, Punjab.

As per EIA Notification, 2006 & its amendments for development projects covering an area of

50 ha and/ or built up area greater than 1, 50,000 m2 are designated as 8 (b) as per the schedule

of the notification and require EIA/EMP study to obtain prior environmental clearance from

respective State Environmental Impact Assessment Authority (SEIAA).

This project is thus categorized as 8 (b) under Schedule of the Environmental Impact Assessment

Notification and requires Environmental Clearance from the State Environment Impact

Assessment Authority, Punjab as the built up area is 1,51,314 m2 so EIA/EMP study is required.

The EIA/EMP study has been carried out considering baseline environment study carried out

during for Oct- Dec 2013 of "Knowledge Park/IT Park" GMADA, Sector-66, 82 & 83, SAS

Nagar, Mohali, Punjab project with due permission of SEAC, Punjab. Additionally, one month

study (12th May to 08th June, 2016) has been carried out.

For the purpose of certain environmental components, the radius of impact has extended/studied

up to 10 km. The EIA has been conducted to establish the baseline environmental setting in the

study area, assessment of potential impacts on different environmental components, design of

mitigation measures so as to keep impacts within acceptable limits and strengthen the positive

impacts.

This chapter summarizes the findings of the EIA study to aid in decision making and provides

project related information and environmental impacts to non-technical sections of society. The

summary highlights the baseline environmental status, key environmental issues and their likely

impacts and also lists the major recommended mitigation measures to attenuate the impacts.




10.2 PROJECT SITE

The project site is well connected via. road, railway and airway. The nearest railway station is

Sahibzada Ajit Singh Railway Station which is 2.5 km away from the project site in NW

direction. The nearest airport is Mohali International Airport at a distance of 4 km from the

project site in NE direction.

NIPER and Fortis Hospital are 5 km away.

10.3 PROJECT FEATURES

The total population of the project is 13,528 persons. Salient features of the project are as

presented in table below:

The project will be implemented over a span of four to fivee years from the commencement of

construction.




10.4 ENVIRONMENTAL SETTING OF THE STUDY AREA

The baseline environmental status was assessed based on primary and secondary data collected

either through in-site field observation or obtained from agencies such as Irrigation Department,

India Meteorological Department (IMD), Central Ground Water Board, Geological Survey of

India, State Ground Water Department, State Pollution Control Board, Census of India and Local

Forest Department, Non -Governmental Agencies. The baseline status established from analysis

of secondary and primary data and predicted impacts are discussed below. The proposed

mitigation measures are also provided along with.


The land is designated for development of commercial projects. The site is allotted to the project

pronpnet for development of commercial project by GMADA

.

The construction phase poses the threat of soil contamination and soil erosion, mainly during the

construction phase. Inadequate solid waste management may also cause soil contamination

during operation phase. The estimated waste generation during operation phase is 3877 kg/ day.

During construction phase, excavation related work will be avoided during the monsoons and

site clearing will be carried out for specific areas being developed. All wastes from site will be

regularly removed and disposed/ sold. An efficient solid waste management is proposed

comprising door-to-door waste collection, segregation of solid waste management facility within

the site, and their disposal. Solid waste will be disposed by sale of recyclable wastes to vendors.

10.4.2 Water environment

The water requirement during construction phase will be met from private water tankers. A

combination of efficient water management strategies will be adopted to reduce water

consumption, reuse of treated wastewater to reduce freshwater demand and rainwater harvesting

to replenish groundwater is proposed to have a positive bearing on the water environment of the

region.




A Sewage Treatment Plant (STP) of capacity 627 KLD will be set up to treat and reuse

wastewater.


During construction phase, the major air pollutant of prime concern is PM 2.5, PM10 as impacts of

other emissions such as SO2, NO2, and CO will not be significant because the nature of sources

is such that the emissions are distributed spatially as well as temporal. Monitored average PM2.5,

PM10 level exceeded NAAQS at all the five locations. The levels of PM 2.5, PM10, NO2, SO2 and

CO at all the five locations were within the standards prescribed by NAAQS at all the five

locations. Thus dust emissions from construction activities shall require comprehensive

mitigation measures and best construction practices.

Adequate stack heights will be proposed for D.G. Sets of total 11,000 kVA capacity (3 x 2000 +

3 x 1500 + 1 x 500 kVA) above the ground to provide for sufficient dispersion of pollutants.

Water sprinklers will be used to suppress dust during construction. During the operation phase,

green belt and green area development is proposed to restrict and absorb air pollutants.


Noise levels were observed at four locations within the study area. The noise emitted from

heavy-duty construction equipment’s during construction period being high shall require

occupational preventive measures and temporary noise barriers for noise attenuation. The

construction period being about four to five year duration, will require significant mitigation

measures such as restricted loud noise activities to daytime, provision of PPEs and acoustic

enclosures for D.G. Set.

In the operation phase, noise pollution will be checked through acoustic enclosures of DG Sets

and green belt plantation.

10.4.5 Biological environment

There is no tree cutting involved in the project. However, the project will have 9517 m2 of green

area during operational phase. There will be development of avenue plantations, lawns, etc. The




proposed landscaping will include native species that will attract local birds and insects, reduce

pollution and improve aesthetics and micro-climate of the region.

10.4.6 Socio-economic environment

The proposed project does not call for any land acquisition or change in the land use pattern. The

execution of the project will not disturb the people living in area as there will be no blasting and

large scale digging. The project will generate employment opportunities for both skilled and

unskilled workers in the vicinity, which will produce multiple effects on the life and economy of

the local people. Thus from socio-economic point of view the project is beneficial to the people

and can be executed with little hesitation.

10.4.7 Energy efficiency

The total energy demand of 7544 KW for the project will be met by Punjab State Power

Corporation Ltd. 7 D.G. sets of total capacity 11000 kVA (3 x 2000 + 3 x 1500 + 1 x 500 kVA)

are proposed to provide backup in case of power failure. Various provisions are made to reduce

the energy efficiency of the building, such as use of solar energy, provision of low energy

fixtures, design features to maximise sunlight and use of energy efficient material to improve

energy efficiency.

10.4.8 Other

Resource Conservation: A concerted effort is made towards resource conservation by way of

using recycled building materials, fly-ash bricks (up to 35%), reduced water consumption and

improving energy efficiency of the building.

Indoor Air Quality: Special attention will be given to maintaining indoor air quality through

use of low VOC paints, provision of adequate ventilation, proper storage of chemical and

cleaning materials.

Safety: A network of manned security gates, security men, closed circuit TV and intercom

facilities are proposed to ensure safety of the occupant. The buildings will also be provided with

adequate fire tenders, fire alarms and water sprinklers.




10.5 ENVIRONMENTAL MANAGEMENT PLAN

Adequate environmental management measures will be incorporated during the entire planning,

construction and operating stages of the project to minimize any adverse environmental impact

and assure sustainable development of the area.

For the effective and consistent functioning of the campus, an Environmental Management

System (EMS) will be established at the site including an Environmental Management cell for

implementation of the EMP and monitoring plan, training and awareness, audits and

maintenance of records.

M/s WTC NOIDA Development Company Pvt. Ltd. manages the environmental

condition/compliance through an in house team. Environment Management Cell structure is

shown below:

Based on the environmental assessment, the associated potential adverse environmental impacts

can be mitigated to an acceptable level by adequate implementation of the measures as stated in

the EIA and the EMP. Some of the benefits from the project are:

Use of solar energy for street lighting

Provision of green walls/green terraces

Use of fly ash bricks.

Use of steel manufactured from recycled content

Provide permeable paving to control surface water runoff

Rainwater harvesting

Meet all requirements for buildings in moderate earthquake prone areas.
