1.3 What are the likely impacts of the proposed activity on the existing facilities adjacent to theproposed site? (Such as open spaces, community facilities details of the existing landusedisturbance to the local ecology).

The impact due to the proposed project may be increase in the traffic loads, increase in noise levels

during construction activities, and dust emission, emanating from various construction activities. Due

care will be taken during construction as well as operational phase to minimize the impact on

surroundings such as shielding of construction site, wetting of roads and stockpiles etc.

There will not be any significant impacts from the proposed activity on the existing facilities adjacent

to the proposed site, as the GMADA is developing all the facilities such as connectivity, roads, open

space, water supply, drainage and Sewer etc. keeping in view the land use as per Master Plan. All

construction activities will be confined within the project area. There will be no physical changes

outside the project boundary. Development and Construction of proposed project will be done as per

applicable norms/byelaws and building codes.

There is no disturbance to the local ecology. 38.5% of Present Development area will be developed as

soft green. The project will have positive impact on the existing environment. Since the project site is

falling in the city itself so no significant disturbance is anticipated.

1.4 Will there be any significant land disturbance resulting in erosion, subsidence & instability?(Details of soil type, slope analysis, vulnerability to subsidence, seismicity etc may be given).

There will be some land disturbance due to the upcoming project as the project will involveclearing, grading and construction of impervious surfaces.

Following mitigation measures will be used to mitigate the same:

Construction planning will be done to minimize exposed soil during times of the year when the

potential for erosion is high, for example during summer.

Site will be stabilized and erosion control measures will be adopted.

Suppression measures, such as watering exposed area will be taken during the course of

construction.

Stockpiles will be located with the slope not greater than 2:1 (horizontal or vertical).

Size and number of stockpiles will be kept minimum and will be located away from drainage

line.

Soil Type:

The area is poor as regards mineral wealth. It is mostly a plain of alluvial type. It also has loam to

heavy loam and sand to sandy loam soils in certain parts of the district. The area can be broadly

grouped into two depending upon its geomorphic features as alluvial fan and alluvial plains.

Alluvial fans are deposited by hill torrents with a wavy plain rather than a steep slope. Adjacent

to the alluvial fan are the alluvial plains which forms a part of large Indo- Gangetic Quaternary

basin comprises of thick sand and silty sand layers inter bedded with silt and clay beds. The

alluvial plains are of vital economic value as it supports the dense population of the district. The

soils are mainly developed on alluvium under the dominant influence of climate followed by

topography and time. The major soil type of the district is weakly solonized tropical arid brown

soils.

Soil at the site is brown sandy silt/ clay with gravels. Soil analysis report is attached as Annexure

III

Erosion / Subsidence: Project will provide ample green space. Therefore, it will not cause any soil erosion,

subsidence or instability problems. The natural slope of the area has not been disturbed. The

contour map is attached as Annexure VIII

Seismicity:

Based on tectonic features and records of past earthquakes, a seismic zoning map of India has

been prepared by a committee of experts under the auspices of Bureau of Indian Standard (BIS

Code: IS: 1893: Part I 2002). In this seismic zoning map, the area of Mohali lies in Zone IV.

Large quantum of broken pieces of bricks and masonry arise as waste. This could be reused as

appropriate.

Metal waste is generated in the form of pipes, conduits, and light sheet material used as

reinforcement in the concrete. Metal scraps will be sold to authorized recyclers.

Construction Debris (Bricks, Cement, Concrete and Mortar) and other miscellaneous materials

that arise as waste include glass, plastic material, paper, etc: Part of the generated debris will be

reused in road construction, backfilling and leveling, spare debris (if any) will be disposed off as

per the norms.

The fertile top soil will be reused for horticultural purpose.

Proper care shall be taken to ensure that there is no leakage of oil from machineries. Spillage of

oil, if any, from the machineries will be properly collected and disposed off.

Domestic solid waste generated will be managed as per MSW (M & H) Rule.

1.8 Will the low-lying areas & wetlands get altered? (Provide details of how low lying andwetlands are getting modified from the proposed activity).

Site is fairly plain with an altitude 300 m above mean sea level. Drainage pattern and slope of

proposed site is toward North direction of site. No wetlands are present in and around the project

site.

.

1.9 Whether construction debris & waste during construction cause health hazard? (Givequantities of various types of wastes generated during construction including the constructionlabour and the means of disposal)

Wastes which will be generated during the construction phase include the following: Excavated

materials from earthworks (e.g. cuttings, artificial lake excavation, foundation etc), general

construction waste (e.g. wood, packing material, scrap metal, concrete and empty cement bags);

hazardous wastes generated, if any, and Municipal wastes generated by site workers. Part of the

non-hazardous construction waste (from earthworks) will be reused in road construction, general

construction waste will be sold to recyclers and hazardous waste managed as per norms.

Quantification of waste is done in Table 5.

Excavated Materials from Earthworks

It is estimated that approximately 35000 m3 of earth material will be excavated during initial

construction for foundations & lakes etc (Table 4). Maximum percentage of excavated material

will be re-used within premises for different purposes. The excess earth would only be the


FORM-1A


construction wastes and will not cause any health hazards. However, its proper disposal shall be

ensured as per prevailing local norms.

Municipal Waste & Other waste

Municipal wastes comprise food wastes, packaging and waste paper. Generation rate of solid

waste from labour colony will vary from place to place due to habits and living condition.

Approximately 0.25Kg/capita/day of municipal waste may be expected during construction phase.

The domestic waste water generated from construction camps shall be disposed of through mobile

sewage treatment plant.

Hazardous Waste

Hazardous waste could include diesel oil spillage from vehicles, DG Sets, paints and emulsions.

Only PUC certified vehicles will be allowed inside the campus and it will be ensured that there

are no spillages. DG Sets, paints and emulsions will be stored properly, so as to eliminate any

chances of spillage.

The Impact, if any, on soil during construction phase will be marginal and reversible in nature.

One important source of the present water supply in the Greater Mohali region is ground water.

Generally, the existing ground water supply and distribution system comprises of the tube wells,

storage or service reservoirs and an extensive network of pipelines. Water extracted from tube

wells is chlorinated prior to distribution to end users. After chlorination, the water is pumped into

service reservoirs and then distributed to users through a large network of mains of various sizes

and types.

The current municipal water supply and distribution system only covers certain areas of the

Greater Mohali Region. For areas not covered under the current municipal water supply and

distribution system, the residents depend on private wells and storage tanks for their domestic

water.

In addition, approval has been obtained for the planning of 6 pipe lines (20 MGD per pipe line) to

supply water from the Bhakra Canal located about 25 km away from the Greater Mohali Region.


FORM-1A


Four of the pipe lines will be supply to Chandigarh while the remaining two pipe lines will be

supplying to Mohali.

In future, development of dual pipeline systems would be proposed for potable water supply

system and the recycled water supply system separately.

concerned regulatory body.

2.8 What would be the impact of the land use changes occurring due to the proposed project onthe runoff characteristics (quantitative as well as qualitative) of the area in the postconstruction phase on a long-term basis? Would it aggravate the problems of flooding or waterlogging in any way?


FORM-1A


Rainfall of 617 mm/year has been taken and peak run off of 40 mm/hr has been taken for rainfall

calculations. The project will increase the paved areas and thus the runoff from the project area is

expected to increase due to reduced infiltration. No adverse impacts are envisaged due to proposed

project on the run off characteristics of the area as adequate arrangements have been made to trap the

rainwater and suitable water system has been provided, along with a functional mechanism to use the

collected rain water.

During the post-construction phase, runoff will not be allowed to stand and create water logging or

enter into the road side or nearby drain. Adequate measures shall be taken to collect such run off.

Suitable garlanding drain as per the existing contours of the plot will be developed. The project will

not aggravate the problems of flooding or water logging in any way, as the topography is plain.

2.9 What are the impacts of the proposal on the ground water? (Will there be tapping of groundwater; give the details of ground water table, recharging capacity, and approvals obtainedfrom competent authority, if any).

The ground water depth at the site, as measured during soil investigation is 8.6 mbgl (Annexure III).

There will be no impact on the groundwater by the proposed project; fresh water shall be supplied

through municipal water supply while treated water shall be recycled for other low end uses.

9% of total fresh water requirement (i.e. 18 KLD) will be met from roof top rainwater collected and

stored in UGT.

Excess water will be used to recharge ground water through rainwater harvesting pits, after taking

permission from CGWA.

Appropriate permissions from local municipal authorities will be procured before starting of the

project.

Ground water status of S.A.S Nagar District:

Exploratory drilling has revealed 4-13 saturated granular zones comprising of fine to coarse sand,

silt and kankar up to the total drilled depth of 460 m in Kharra and Sialba Majra blocks. The

discharge ranges from 870-2407 lpm for 21.65 and 11.36 m draw down respectively. The

transmissivity and hydraulic conductivity varies between 55 to 862m2/day and 7.4 -48m/day

respectively. The storativity value ranges between 7.3x104-2.4x10-3, which clearly indicates a

leaky confined condition.

The S.A.S Nagar district is occupied by Quaternary Alluvial deposits belonging to the vast Indo-

Gangetic alluvial plains, which forms the main aquifer system. Groundwater occurs under phreatic

conditions in the shallow aquifers while leaky confined to confine conditions occur along the

deeper aquifers of Quaternary alluvial deposits.

Potential Aquifers

The principal aquifer system of the district is Alluvium. In major part of the district, the water

level ranges between 5 and 10 m while the water level in the north western and eastern part is


FORM-1A


between 10 to 20 meters, in the extreme western part of the district water levels are around 30

meters. In the southern part of the district water level ranges from 2 to 5 meters.

Seasonal fluctuation shows that, in general, there is an overall decline in the water level except few

isolated patches.

2.10 What precautions/measures are taken to prevent the run-off from construction activities

polluting land& aquifers? (Give details of quantities and the measures taken to avoid the

adverse impacts).

Surface water quality may be affected with the discharge of the runoff from the project site, during

construction. The impact to the surface water bodies could arise from the increased soil erosion from

excavated site, only to increase in the suspended particles and turbidity of runoff water from the site.

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

soon as the 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. Plantation of trees will start from

construction phase itself. No runoff will be disposed outside the project boundary.

Effective measures will be adapted to reduce the storm water run-off from the construction site-

Ensuring vehicles stick to the access track.

Cleaning all mud and dirt deposited on roads from construction-related activities.

Excavation work will not be carried out during monsoon season.

Effective sediment control.

Preventing wastewater from brick cutting activities and stockpiles entering the storm water system.

Construction material will be stored in temporary shed at the earmarked place and will be covered

ensuring that no leachate or spoilage of land occurs.

Curing water will be sprayed and, after liberal curing, all concrete structures will be painted with

curing compound & covered with gunny bags, then the water will be sprayed.

To prevent surface and ground water contamination by oil & grease, leak proof containers would

be used for storage and transportation of oil /grease. The floors of oil /grease handling area would

be kept effectively impervious.

2.11 How is the storm water from within the site managed? (State the provisions made to avoidflooding of the area, details of the drainage facilities provided along with a site layoutindication contour levels).

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

has been planned. All building roof water will be brought down through drain water pipes. Water

thus collected will be stored in UGT and used to meet fresh water requirement, along with municipal

water supply.


FORM-1A


2.12 Will the deployment of construction labourers particularly in the peak period lead tounsanitary conditions around the project site (Justify with proper explanation).

Sewerage and solid waste will be generated from temporary labour camps on site, which will be

temporary in nature during the initial construction phase. Waste shall be segregated at source. Bins

shall be placed near the camps for solid waste collection. The solid waste will be properly disposed

as per MSW Rules 2016. The sewage will be disposed through mobile toilets and mobile STP.

Therefore during construction, there will not be any unsanitary conditions around the project area.

2.13 What on-site facilities are provided for the collection, treatment & safe disposal of sewage?(Give details of the quantities of wastewater generation, treatment capacities with technology& facilities for recycling and disposal).

The only sources of wastewaters are from toilets, food courts, etc., in the campus and therefore

domestic in nature. The waste water generated from campus (i.e. 275 KLD) will be treated in the

STP of 350 KLD (installed at 25% higher capacity) up to tertiary level. Tertiary treated water will be

recycled for various low end uses including toilet flushing, cooling of HVAC and horticulture

purposes.

Based on the quantity & quality of wastewaters as also the treatment of same at other places, it is

proposed to treat the wastewaters in an MBR (Membrane Bio reactor) technology. (Schematic: Fig

5)

The treatment methodology includes. Bar screen chamber (Separate screen shall be provided Laundry waste)

flushing of toilets. Design and details of dual plumbing shall be providing during compliance of

conditions.

3. VEGETATION

3.1 Is there any threat of the project to the biodiversity? (Give a description of the localecosystem with its unique features, if any).

No, the project will not pose any threat to the biodiversity of the locality. The proposed site is clear

from any type of vegetation and wild life or domesticated habitats except few species of grasses &

bushes as ground cover. There are some shrubs (Prosopis juliflora), weeds (Calotropis procera,

Lantana) and grasses seen on the plot.

The water body (pond) planned within site will help in attracting aquatic & avian fauna. Moreover,

quite a number of trees will be planted. The species will be predominantly native in nature so that

they merge with the local ecosystem.

Ghaggar River is Main River flowing at a distance of 6.5 Km (SE) from proposed project site.

Sukhna Lake is 14 km (NE), Sukhna Wildlife Sanctuary situated at 15 km (NE), Sector 21 Bird

Sanctuary is situated at 10.8 km (NE) and Chattbir Zoo is 6.5 km (SE) from proposed project.

Reserve forests around project site are:

Dariya Reserve Forest: 9 km (SE)

Nepli Reserve Forest: 18 km (NE)

Khol Reserve Forest: 20 km (NE)

All the waste (liquid/solid/gases) will be managed onsite as per Rules. The impact due to proposed

project will be minimal.

Flora of the study area (Secondary sources): Acacia catechu (Khair), Dalbergia sisoo

(Shisham), Azadirachta indica (Neem), Bombax ceiba (Semal), Bauhinia racemosa (Kachnar),

Emblica officinalis (Amla), Prosopis juliflora (Musket), Cassia fistula (Amaltas), Zizyphus jujoba

(Ber), Ashoka, Chitwan, Scholar Tree, Kaner, Amaltas, Gulmohar, Peepal, Bottle Brush & Bottle

Palm etc.

Fauna of the Study area (Secondary sources): Mostly domestic animal’s viz. Dog, Cat, Horse,Donkey & Cattle etc.

Avifauna: Common Crow, Chukar Partridge, Duck, Hornbill, Snow Partridge & Rain Quail etc.


FORM-1A


Since, Chattbir Zoo lies in study area (within 10 km of project site) associated flora and fauna may

be accounted. But this is a protected area and more than 6.5 km away from project site, the

anticipated impacts on biodiversity here would be negligible.

Endangered and Threatened Species

Endangered and threatened animals of India have been listed in the Schedule I and Schedule II of

the Wildlife (Protection) Act 1972 (amended in 2001). No threatened, rare, endangered, or

endemic species were observed during the survey in core zone.

3.2 Will the construction involve extensive clearing or modification of vegetation? (Provide a

detailed account of the trees & vegetation affected by the project).

There are no significant vegetation, except some ground cover within the site thus no extensive

clearance or modification of vegetation.

3.3 What are the measures proposed to be taken to minimize the likely impacts on important

site features? (Give details of proposal for tree plantation, landscaping, creation of water

bodies etc along with a layout plan to an appropriate scale).

Due care will be taken to protect the important site features:

Tree plantation will be done to protect the site features such as topsoil erosion, ground water

attenuation and avoiding contamination by leachate.

The excavated soil will be stored at earmarked places protected from contamination and from

polluting the existing features and will be used for surface leveling and for creation of landscaped

areas.

Adequate measures will be taken to minimize the likely impacts of the proposed project on the

surrounding as well as the project site itself and documented in the Environmental Management

Plan.

General principles in greenbelt design considered for this study area:

Type of pollution likely air, noise, and water and land pollution generated from the activities at

the site.

Agro-climatic zone and sub-zone where the greenbelt is located

Water quantity and quality available in the area

Soil quality in the area.

Green & Open Areas

Total open area including Green, Lakes and Paved will be around 157,390 m2 (38.5% of present

development area).


FORM-1A


Total no. of trees required: =(1 Tree/ 80 m2 of open Area): 1646 Trees

=1,31,671 / 80

= 1646 Trees

Proposed = 2500 Trees

A combination of evergreen and ornamental flowering trees, palms, shrubs and ground covers,

which are indigenous and native to the area, will be planted along the sides of the roads and in

open spaces & set back area within the campus.

Landscaping is an important element in altering the microclimate of a place. Proper landscaping

reduces direct sun from striking the buildings and heating up building surfaces, prevents reflected

light carrying heat into a building from the ground or surfaces, creates different airflow patterns

and can be used to direct or divert the wind advantageously by causing a pressure difference.

Shade created by trees and the effects of grass and shrubs reduce air temperature adjoining the

building and provide evaporative cooling. A study shows that the ambient air under a tree is 20C

to 2.50C lower than that for adjacent un-shaded areas.

Parks & Avenue Plantation

Ornamental trees with spreading branches, shade giving with colorful flowers for employees to

relax and suitable patches of lawns shall be provided. The following trees proposed to be planted

in the proposed project.

Trees with colonial canopy with attractive flowering.

Trees with branching at 10 feet and above.

Trees with medium spreading branches to avoid obstruction to the traffic, fruit trees to be avoided

because children may obstruct traffic and general movement of public.

The selection of plant species for the development depends on various factors such as climate,

elevation and soil. The project site falls in Central Plain Zone. The list of plant species, which can

be suitably planted, and having significant importance are provided in Table-14.

human dominated areas. Therefore, this project will not be barrier for movement of any faunal

species. Existing trees, shrubs and herbs of surrounding area of site will attract the arboreal species.

4.2 Any direct or indirect impacts on the avifauna of the area? Provide details.

There is no impact on the avifauna of the area. Due to the provision of plantation on the project siteit is expected that site will attract small fauna.

4.3 Prescribe measures such as corridors, fish ladders etc to mitigate adverse impacts on fauna.

As there is no displacement of fauna, no mitigation measures are required and provided.

5 AIR ENVIRONMENT

5.1 Will the project increase atmospheric concentration of gases & result in heat islands? (Givedetails of background air quality levels with predicted values based on dispersion modelstaking into account the increased traffic generation as a result of the proposed constructions).

Increased traffic generation and DG set emission due to project is not going to cause significant

increase in atmospheric concentration of gases and will not result in heat island formation. The

minor impacts of emissions from traffic will be neutralized by developing a thick green belt along


FORM-1A


the periphery and internal road side. To minimize the effect of emissions, adequate stack height as

per CPCB standards will be provided.

During construction phase, dust emissions will be the main pollutants associated within on-site

roads, (paved and unpaved), stockpiles and material handling. Regular water sprinkling will be done

and construction material will be transferred in trucks covered with tarpaulin.

5.2 What are the impacts on generation of dust, smoke, odorous fumes or other hazardous gases?Give details in relation to all the meteorological parameters.

The impacts of dust and gaseous pollutants due to different construction activities will be localized.

pathways, footpaths etc., with areas under each category.

The site layout plan showing traffic circulation/ movement pattern is enclosed as Annexure VII.

5.5 Will there be significant increase in traffic noise & vibrations? Give details of the sources and

the measures proposed for mitigation of the above.

During the construction phase, some noise will be generated through the operation of construction

machines, excavators, DG set, etc. Following measures should be taken; into consideration to

mitigate the noise at construction site:


FORM-1A


The project shall not employ such excavation/ construction machines, which generate noise

levels much more than 85 dB (A),

Silencers shall be fitted on construction machines and DG set,

Acoustic enclosures should provide to DG set at the construction site,

Earmuff and other protecting, devices shall be provided to labour working in high noise

generation machines.

During post construction phase, not much noise is anticipated, on account of project being a

technology park. However, noise generated due to vehicular movement, operation and maintenance

will be mitigated by adopting following measures.

DG set will be silent type with anti vibration pads.

Administrative control by display of slogans and sinages

Green belt/plantation along the internal roads will also work as noise barriers.

5.6 What will be the impact of DG sets & other equipment on noise levels & vibration in &

ambient air quality around the project site? Provide details.

Impacts on Air Quality and Noise levels due to DG Sets & other equipments

Noise will be emitted during construction due to operation of construction machinery like transit

mixture, concrete pumps, tower cranes, Air compressors etc. Vulnerable receptors would not be

significantly affected. Noise generated in this phase would be spread throughout the site depending

upon equipment operation at a location. Impact on onsite workers are expected but will be mitigated

by the use of PPE like earplugs and earmuffs.

One of the major sources of noise during operational phase will be the diesel based generator which

will be housed in the basement. Impacts on ambient air during operation phase would be due to

emissions from the stacks attached to stand by DG sets only during grid power failure

Mitigation Measures Back up DG sets will comply with the applicable emission norms.

Adequate stack height for DG sets will be provided as per norms.

Back up DG sets will be used only during power failure.

Monitoring of emissions from DG sets and ambient air quality will be carried out as per norm.

DG set will be silent type with anti vibration pads.

As per Greater Mohali Area Development Authority (GMADA) Master Plan 2031, the project has

been allotted 50 Acres of land in Knowledge Park, for development of IT Park. The land use of the

Sector 83 A is Industry & Warehouse.

All the Social setup like Primary School, Degree College, Roads, Electricity and open market are

available in vicinity of site. Good employment and development opportunity in Industrial area of

Mohali is present because of availability of natural and manmade resource like Highways, Water &

Power. Several Group housing schemes &Townships are being planned or under construction in

the vicinity.

Project site is located adjacent to 60 m wide road. The distances of various Infrastructural facilities

are:

NH 64- 5 km (SE)

NH22- 8.8 km (E)

SH4- 4 km (W)

Aerocity Road: 2 km (NE)

JLPL Industrial Area: 1.5 km (N)

Mohali Industrial Area- Phase 8: 8 km (NW)

Chandigarh Airport: 6 km (NE)

Chandigarh Railway Station: 11 km (NE)

Apart from this, State Road transport bus services provide regular and frequent connectivity to the

people to and from Chandigarh, Panchkula & other cities of Punjab & Haryana. The proposed site

is connected with road and rail network.

7.3 Will the project cause adverse effects on local communities, disturbance to sacred sites or othercultural values? What are the safeguards proposed?

Based on the nature and type of impacts, the assessment has been divided into three category i.e.

positive, negative and negligible impacts. For example the positive impacts are: job creation for

men and women, better utilization of land, preservation of environment, and infrastructure

development. Long term impacts have taken into account i.e. relocation, demography, aesthetics,

accessing utilities, and impact on archeological sites. Negative impacts include adverse impacts on

health, air pollution including noise, road safety, and odors.

Job opportunity: The project will result in creation of employment opportunities. The benefit

relate to the direct employment associated with the construction of the facility during construction

and employment in the IT park during operation phase.

Appreciation in land value: With Infosys IT Park coming in the area the prices of the land will

appreciate considerably. Hence the proposed project will have beneficial impact.
