IDENTIFICATION, PREDICTION AND EVALUATION OF IMPACTS

Environmental impact can be defined as any alteration of environmental conditions, adverse or

beneficial, caused or induced by the action or set of actions under consideration.

Various operations involved in the project have been studied in details to identify, predict and

evaluate impacts on various environmental components. The identified impacts were quantified

using mathematical models to a possible extent so as to estimate the future environmental scenario.

AIR ENVIRONMENT

Air pollution has long been recognized as a brain storming issue worldwide. The onset of

technological and scientific innovations in various fields and diverse activities of human race for

its elegance have put extra load on the atmosphere by way of releasing air pollutants like

particulate matter (PM10, PM2.5), sulphur dioxide (SO2), oxides of nitrogen (NOX), carbon

monoxide (CO), unburned hydrocarbon (HC) and other organic as well as inorganic pollutants

including trace metals responsible for causing health consequences. Entry of pollutants into the

atmosphere occurs in the form of gases or particles. Continuous mixing, transformation and trans-

boundary transportation of air pollutants make air quality of a locality unpredictable. The growth

of population, industry and number of vehicles and make the problem of air pollution still worse.

Rapid industrialization and vehicular traffic especially in the urban areas of India is a great threat

to air quality.

sprinklers, etc to mitigate dust generation from the construction site.

2. Design • Travelled distances will be minimized for delivery of materials

• Green building materials viz. fly ash bricks, RMC’s, etc. will be used

to the best possible extent.

3. Vehicles &

• PM emissions from spills will be prevented.

• Material handling operations will be minimized.

5. Road Surfaces • On-site vehicle restrictions will be established.

• Unpaved roads will be properly maintained.

POST CONSTRUCTION PHASE:

The emission sources are mainly due to the vehicular emissions, diesel generator set of cumulative

capacity 3000 kVA (1500 kVA- 2 nos.), Boilers (2 nos. of capacity 850 kg/hr each), & Hot water

generators (2 nos. of capacity 4 lac kcal/hr each). The DG sets are housed in an acoustic enclosure

CONSTRUCTION PHASE:

WATER CONSERVATION TECHNIQUES:

Best construction practices will be adopted to reduce the water demand for construction activities:

• Use of polymer dispersion and air entraining agents to reduce the construction water demand.

• Admixtures will be used to reduce water demand during construction.

• Discouraging the washing of vehicles and equipment on the construction site. Workers will

not allow to wash their personal vehicles on site. Vehicles and equipment that regularly leave

the construction site should be washed offsite.

MANAGEMENT PLAN:

SOURCES MANAGEMENT

• Un-captured run-off

from the site may

contaminate ground

water aquifers.

• The rain-water entering into the pit will be screened for the removal of

heavy silt and other materials.

• Provisions will be made to ensure the construction vehicles stick to the

access track to prevent mud & dirt being deposited on roads.

• Up slope water will be diverted with turf and due care will be taken not

to mix mortar in locations that will drain into storm water system.

• Unsanitary conditions

during rainy season.

• The civil contractor will be made responsible for site sanitation and will

be bound by the management to adhere to healthy level of sanitation.

• There will be no stagnant water at site, as the runoff from the relevant

areas will be systematically drained into the storm water line. There

will be provision of cleaning the storm water line periodically.





Daily water demand will be 350 KLD (fresh: 189 KLD + recycled: 161 KLD). The fresh water

demand will be met from RIICO supply/ ground water.

A. WATER CONSERVATION TECHNIQUES:

Following water conservation techniques have been proposed for the project:

• Dual plumbing system will be adopted to utilize the treated waste water for flushing (22

KLD), make up for cooling towers (126 KLD), landscaping (13 KLD). This will help in

reducing the fresh water demand.

• Dual flushing fixtures will be used to allow different volumes of water for solid and

liquid flushing which will help in conserving the water demand for flushing significantly.

• Water meters will be installed for the following:

o Potable water consumption

o Landscape water consumption

o Hot water consumption through solar systems, at building level

o Treated waste water consumption

• Landscape design & management of irrigation systems:

o Native & xeriscaping plant species: Choose native plant species that need less

water.

o Creating Hydrozones: Grouping of plant according to their water needs to provide

adequate water to all plants without over or under-watering.

o Maintain Healthy Soil: Healthy soils are the basis for a water-smart landscape; they

effectively cycle nutrients, minimize runoff, retain water, and absorb excess nutrients,

sediments, and pollutants.

o Mulching: Incorporate mulch around shrubs and garden plants to help reduce

evaporation, inhibit weed growth, moderate soil temperature, and prevent erosion.

Adding organic matter and aerating soil can improve its ability to hold water.

o Avoid watering during the heat of the day. Water early in the morning to reduce the

evaporation rate

o Drought tolerant species will be selected.

o Turfs will be avoided to the extent possible.




o Central shut off valve will be provided

o Sprinkler landscaping system will be used to conserve water

B. WASTE WATER GENERATION AND TREATMENT:

Approximate 181 KLD waste water will be generated which will be treated in STP of

capacity 200 KLD, based on FAB technology. Physico chemical characteristics of influent

and effluent are given as:

Parameters Influent Treated effluent

pH 7.5 - 8.5 7 - 8

Suspended solids 200- 225 mg/l <5 mg/l

BOD 200 - 250 mg/l <10 mg/l

COD 350 - 400 mg/l <60 mg/l

Oil & Grease 20-25 mg/l <1 mg/l

STORM WATER MANAGEMENT:

Construction phase

Contaminant Sources Impact Mitigation

Sediment &

Floatables

Streets, lawns, driveways,

roads, construction

activities,

During construction, sediment fencing or other erosion

control devices will be used to mitigate the short-term

adverse impacts of sedimentation.

Oil & Grease Roads, driveways, parking

lots etc.

Oil & Grease trap will be provided to remove oil & grease,

suspended matter, and ensure the quality of water.

Storm water control and rain water harvesting will be done as per the standards laid down by

CGWA & BIS. Following measure will be adopted for the same:

Compost Blankets: A compost blanket is a layer of loosely applied composted material placed on

the soil in disturbed areas to reduce storm water runoff and erosion. This material fills in small rills

and voids to limit channelized flow, provides a more permeable surface to facilitate storm water

infiltration, and promotes re-vegetation.




Post Construction Phase:

a. Design:

For good design of rainwater harvesting, following points are to be kept under consideration:

• Ideal location with good ground slope.

• The location has adequate subsurface permeability of the aquifer to accommodate maximum

recharge of rainwater through injection well.

• Rate of filtration should exceed average rainfall intensity.

• Clogging of filtration media should be cleaned periodically.

• Ground water pollution does not take place.

b. Baseline:

The average annual rainfall (based on last 10 years rainfall data) is 597 mm.

deposition. The filtration tank dimension would be 3 m (length) x 3 m (width) x 1 m (depth)

with 0.15 m dia recharge well of 30 m depth depending upon the formation for recharge in

aquifer through vadose zone. Each structure will be capable of handling rainwater volume @
