2.4 Will there be diversion of water from other users? (Please assess the impacts of the

project on other existing uses and quantities of consumption).

No. There has not been any diversion of water from other users. Rise in water demand is a local

phenomenon but the project would only involve spatial shifting of water demand within a region.

2.5 What is the incremental pollution load from waste water generated from the

proposed activity? (Give details of the quantities and composition of wastewater generated

from the proposed activity)

It is expected that the project will generate approx. 95 KLD of Waste Water. The Waste Water

will be treated in the STP provided within the complex generating 100 KLD of recoverable water

from STP which will be recycled within the project.

This wastewater generated will be treated in well designed sewage treatment plant based on FMR

technology.

The following are the input characteristics of the Wastewater:

(a) Daily load : 95 KLD

(b) Duration of flow to STP : 24 hours

(c) Temperature : Maximum 25-30 oC

(d) pH : 7 to 9.5

(e) Colour : Mild

(f) T.S.S. (mg/l) : 150-400 mg/l

(g) BOD5 (mg/l) : 250-300 mg/l

(h) COD (mg/l) : 400-500 mg/l



30

Final discharge characteristics

(a) pH : 6.5 to 7.5

(b) Oil & Grease : <10 mg/l

(c) B.O.D. : <10 mg/l

(d) C.O.D. : <20 mg/l

(e) Total Suspended Solids : <10 mg/l

2.6 Give details of the water requirements met from water harvesting? Furnish details of

the facilities created.

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 plots/shall be connected to

adjacent drain by a pipe through catch basins. Therefore, it has been calculated to provide 47

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 seepage pits 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) Peak hourly rainfall of 50 mm/hr shall be considered for designing the storm water

drainage system.



31

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

hourly rainfall has been considered as 50 mm/hr. The recharge pit of 3.5 m diameter and 4 m

depth is constructed for recharging the water. Inside the recharge pit, a recharge bore is

constructed having adequate diameter and depth. The bottom of the recharge structure will be

kept 5 m above this level. At the bottom of the recharge well, 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 (Existing + Expansion):

Roof-top area = Ground Coverage = 1727.06 m2

Green Area = 1,065 m2

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

= 7100 - (1727.06 + 1,065) = 4,307.94m2

Runoff Load

Roof-top Area = 1,727.06 × 0.04 × 0.8

= 55.265 m3/hr



32

Green Area = 1,065 × 0.04 × 0.1

= 4.26 m3/hr

Paved Area = 4,307.94 × 0.04 × 0.7

= 120.62 m3/hr

Total Runoff Load = (55.265 + 4.26 + 120.62) m3/hr

= 180.145 m3/hr

Taking 15 minutes Retention Time, Total volume of storm water = 180.145 /4

= 45.03 m3

Taking the effective diameter and depth of a Recharge pit 1.5 m and 3.5 m respectively, Volume

of a single Recharge pit = πr2h =3.14 x 1.5 x 1.5 x 3.5 = 24.75 m3

Hence No. of pits required = 45.03 /24.75 = 1.81 pits or 2 Pit

Total of 2 Rain Water Harvesting pits with are being proposed for artificial rain water recharge

within the project premises.

In addition of the above plot owner will provide its own RWH facilities as per norms.

Figure 4: Rain Water Harvesting Pit Design

2.7 What would be the impact of the land use changes occurring due to the proposed

project on the runoff characteristics (quantitative as well as qualitative) of the area in the

post construction phase on a long term basis? Would it aggravate the problems of flooding

or water logging in any way?

The project includes paved areas and thus the runoff will increase due to reduced infiltration.

However, the increased runoff does not cause flooding or water logging as a well-designed storm

water drainage will be provided for the project. The runoff will finally be collected into rainwater



34

harvesting pits for groundwater recharging. The quality of the runoff is expected to improve due

to paved areas.

2.8 What are the impacts of the proposal on the ground water? (will there be tapping of

ground water; give the details of ground water table, recharging capacity and approvals

obtained from competent authority, if any)

Water demand will be fulfilled through Residential Project. No adverse impact is expected on this

account as extensive rainwater harvesting will be implemented across the project site. To reduce

the freshwater demand and hence the groundwater stress, treated wastewater will be used for

landscaping and flushing.

2.9 What precautions/ measures have been proposed to check the surface run-off, as well

as uncontrolled flow of water into any water body?

The following management measures are taken to protect the water quality during construction

phase.

Care has been taken to avoid soil erosion.

Community toilets has been constructed on the site during construction phase and the

wastewater is being channelized to the septic tank in order to prevent wastewater from

entering the water bodies.

Any area with loose debris within the site is being planted.

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

have been used for storage and transportation of oil/grease. The floors of oil/grease

handling area is being kept effectively impervious.

Collection and settling of storm water, prohibition of equipment wash downs, and

prevention of soil loss and toxic release from the construction site has been adhered to

minimize water pollution, same steps were incorporated for the further construction phase.



35

2.10 How is the storm water from within the site managed? (State the provisions made to

avoid flooding of the area, details of the drainage facilities provided along with a site layout

indication contour levels).

Most of the storm water produced on site will be harvested for ground water recharge. Thus

proper management of this resource is a must to ensure that it is free of contamination. A detailed

Storm Water Management Plan will be developed which will consider the sources of storm water.

The plan will incorporate best management practices which will include the following:

Regular inspection and cleaning of storm drains.

Installation of clarifiers or Oil/Water separators system of adequate capacity around

parking areas and garages as per requirement.

Cover waste storage areas.

Avoid application of pesticides and herbicides before wet season.

Conducting routine inspections to ensure cleanliness.

Preparation of spill response plans, particularly for fuel and oil storage areas.

Provision of silt traps in storm water drains.

Good housekeeping in the above areas.

2.11 Will the deployment of construction laborers particularly in the peak period lead to

unsanitary conditions around the project site (Justify with proper explanation).

No, mostly local laborers have been employed during the construction phase and thus negligible

quantities of wastes is generated. Mobile toilets have been provided and the wastewater generated

is being collected in septic tanks. The same provision were made for the further construction.

2.12 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).



36

It is expected that the project will generate approx. 95 KLD of Wastewater. The Wastewater will

be treated in the STP provided within the complex generating 100 KLD of recoverable water from

STP which will be recycled within the project and surplus treated water will be discharged to

nearby sewer.

2.13 Give details of dual plumbing system if treated waste used for flushing of toilets or

any other use.

Dual plumbing system will be provided to utilize this treated waste and serve for non-contact uses

such as flushing, landscaping.

3. VEGETATION

3.1 Is there any threat of the project to the biodiversity? (Give a description of the local

ecosystem with its unique features, if any).

There is no such area has been anticipated.

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

(Provide a detailed account of the trees & vegetation affected by the project)

The project does not support any significant vegetation. It is proposed to develop a peripheral

shelter belt of native plant species to enhance the aesthetic value of the region and also provide an

excellent habitat for various faunal groups.

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?)

Total green area measures 1065 m2 (15% of total plot area) which is area under tree plantation

within the residential plots and along the roads. Evergreen tall and ornamental trees and

ornamental shrubs has been proposed to be planted inside the premises. Parks will also be

developed by the management, which will be area under tree plantation within the plots and along

the roads.



37

4. FAUNA

4.1 Is there likely to be any displacement of fauna both terrestrial and aquatic or

creation of barriers for their movement? Provide the details.

No. The existing land use around the residential site is urban and does not provide a habitat for

wild species. The green belt development within project site will provide a good habitat for the

native avifauna.

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

The project will not have any direct or indirect impacts on the avifauna of the area. However,

planting of trees in the greenbelt will be an attraction to the local avifauna.

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

fauna.

Not applicable

5. AIR ENVIRONMENT

5.1 Will the project increase atmospheric concentration of gases & result in heat islands?

(Give details of background air quality levels with predicted values based on dispersion

models taking into account the increased traffic generation as a result of the proposed

construction).

During post construction phase, cars, scooters/motorcycle will be owned by the residents.

Vehicular emissions will be major source of air pollution in addition to DG sets. Quantum and

dispersion of pollutants from vehicular emission will depend upon the following:

Volume of traffic on the roads

Meteorological conditions

Emission sources from DG sets

The pollutants of primary concern are PM, NO2 and CO released from vehicular emission. The

dispersion of vehicular emissions would be confined within 100 m from the road and

concentration will decrease with the increase in distance from road. It is anticipated that the



38

contribution of vehicular emissions in ambient air quality will be marginal but well within the

stipulated National Ambient. At higher wind speed dispersion will be faster.

Mitigation Measure: The project will involve development of green belt inside the premises of

and avenue plantation along the internal roads, which will work as barrier for the movement of

pollutant and help in air pollution control

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.

Source of pollution:-

DG set operation

Vehicular movement

Impacts on Air Quality due to DG Sets and vehicular emissions:

Impacts on ambient air during operation phase would be due to emissions from the stacks

attached to backup DG sets only during grid power failure.

Increase of CO level.

Mitigation Measures for Impacts of DG Sets and other vehicular emissions on Ambient Air

Quality:

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

norms.

CO detector will be installed at the basement to check the concentration CO level in the

basement.

5.3 Will the proposal create shortage of parking space for vehicles? Furnish details of

the present level of transport infrastructure and measures proposed for improvement

including the traffic management at the entry and exit to the project site.



39

Adequate provision will be made for car/vehicle parking at the proposed project site. There are

also be adequate parking provisions for visitors so as not to disturb the traffic and allow smooth

movement at the site.

5.4 Provide details of the movement patterns with internal roads, bicycle tracks,

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

Internal roads of adequate width, footpaths/pedestrian pathways are well planned for the Group

Housing Project.

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.

No significant impact of noise has been anticipated within and outside of the project site due to

provision of wide roads for smooth flow of traffic and avenue plantation along the roads. Noise,

due to the traffic, within site, will result in a marginal increase in the noise levels, which will

cause slight increase in noise level.

5.6 What will be the impact of D.G. sets and other equipment on noise levels and

vibration in ambient air quality around the project site? Provide details.

During operation, vehicular movement and operation of DG sets are the major sources of noise

pollution. DG set will not be continuously operational and moreover it will be placed in suitable

enclosures, hence no or negligible impact is anticipated.

Impacts on Air Quality due to DG Sets:

• Impact on ambient air during operation phase would be due to emissions from DG stacks.



41

Mitigation Measures for Impacts of DG Sets on Ambient Air Quality:

• DG sets will comply with the applicable emission norms.

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

• 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

norms.

Noise Control Measures for DG sets:

• DG sets will be installed in the basement to minimize the impact on ambient noise.

• DG room will be provided with acoustic lining / treatment to insure 25 dB (A) insertion loss

as per the regulations.

6. AESTHETICS

6.1 Will the proposed construction in any way result in the obstruction of a view, scenic

amenity or landscapes? Are these considerations taken into account by the proponents?

The site lies in an urbanized settlement and is well planned. Thus, no obstruction of view or scenic

beauty or landscape is anticipated. Furthermore, the construction has been planned in such a way

that the organized open spaces and landscaped areas rendered the plot aesthetically appealing.

6.2 Will there be any adverse impacts from new constructions on the existing structures?

What are the considerations taken into account?

No impacts anticipated.

6.3. Whether there are any local considerations of urban form & urban design

influencing the design criteria? They may be explicitly spelt out.

The project strictly follows the Area Building Regulation of NBC 2016. All norms on Ground

Coverage, FAR, Height, Setbacks, Fire Safety Requirements, Structural Design and other

parameters have been strictly adhered to.

6.4 Are there any anthropological or archaeological sites or artifacts nearby? State if

any other significant features in the vicinity of the proposed site have been considered?



42

No anthropological or archaeological sites or artifacts are found near the site area.

7. SOCIO-ECONOMIC ASPECTS

7.1 Will the proposal result in any changes to the demographic structure of local

population? Provide the details.

No such changes anticipated.

Construction phase: Since local labourers have been engaged during construction phase, and also was the same for further construction so, alteration to the existing demographic profile of the area is not anticipated.

Operation phase: The changing demography in the area is another impact that needs attention.

The project will mainly lead to spatial redistribution of local population and hence no

considerable influx of population is envisaged owing to the Group Housing Project.

7.2 Give details of the existing social infrastructure around the proposed project.

The project site is well connected through NH-11 (ENE) which is 3 km far from the site. The

nearest railway station is Sanganer Railway station (SSE), about 4.5 km away from the project

site. The nearest airport is Jaipur Airport (East), at 7 km from the project site.

7.3 Will the project cause adverse effects on local communities, disturbance to sacred

sites or other cultural values? What are the safeguards proposed?

Construction phase: There are no religious sites or archeological monuments of historical

significance on the project site. Hence, no adverse impact in this regard is anticipated. Rather, this

phase have been generating jobs that relate to unskilled, semi-skilled as well as skilled labour

category and will continue generate the opportunities in the further construction phase. Few

supervisory positions has been opened up, for which local candidates have been considered based

on merit, same will be incorporated for further construction status

Operation phase: The project will provide state-of-the-art in the area , thereby improving the

quality of life. A Group Housing Project of such scale will also boost the local economy.



43

8. BUILDING MATERIALS

8.1 May involve the use of building materials with high embodied energy. Are the

construction materials produced with energy efficient processes? (Give details of energy

conservation measures in the selection of building materials and their energy efficiency)

In order to reduce the embodied energy, following energy efficient construction material are used

and were used for future construction:

Fly ash bricks

PPC (Fly ash based cement)

PPC can contain up-to 37% fly ash as per BIS Norms

Conventionally, 1kg of cement production releases 900gm of CO2 in the atmosphere. Thus use of

PPC helps to reduce CO2 emission.

On the other hand, conventional bricks create smoke and use high energy.

Following are the advantages of using fly-ash as a construction material:

The fly-ash bricks are lighter in weight by 10 per cent compared to clay bricks, hence

reduce load of the building.

Fly ash bricks absorb less water compared to clay bricks (10 to 12 per cent as against to 15

to 20).

Fly ash bricks are stronger and less susceptible to scratches/breakage. Thus they can be

used for courtyards, pathways and are most suitable for footpaths.

Since PPC consume fly-ash produced from thermal power plant. It is therefore environment

friendly.

Additionally fly-ash as based cement (PPC) requires less water for curing.

8.2 Transport and handling of materials during construction may results in pollution,

noise and public nuisance. What measures are taken to minimize the impacts?



44

Mitigation Measures for Air Pollution during Construction Stage:

• Construction materials are suitably covered with tarpaulin cover etc during transportation.

• Water sprinkling has been done on haul roads where dust generation is anticipated.

• Raw material storage and handling yard is enclosed from all sides.

• To minimize the occupational health hazard, proper personal protective gears i.e. mask has

been provided to the workers working in the dust prone areas.

Mitigation Measures for Noise Pollution during Construction Stage:

• Administrative as well as engineering control of noise has been implemented.

• Isolation of noise generation sources and temporal differentiation of noise generating

activities ensured minimum noise at receiver’s end.

• To prevent any occupational hazard, earmuff / earplug has been given to the workers working

around construction plant & machinery emitting high noise levels.

• Use of such plant or machinery has not been allowed during night time. Careful planning of

machinery operation and scheduling of operations is being done to minimise such impact.

Above points are also incorporated for the further construction phase.

8.3 Are recycled materials used in roads and structures? State the extent of savings

achieved?

We have utilize fly-ash based bricks/tiles to the maximum extent possible.

Cement bags is being stored under covered area.

8.4 Give detail of the methods of collection, segregation & disposal of the garbage

generated during the operation phases of the project.

The solid waste of the project will be segregated into biodegradable waste and non-biodegradable.

Biodegradable waste and non-biodegradable waste will be collected in separate bins.

Biodegradable waste will be treated in the project premises by organic waste converter. The

recyclable wastes will be sent off to recyclers. Proper guidelines for segregation, collection and

storage will be prepared as per Solid Wastes Management Rules, 2016.



45

9. ENERGY CONSERVATION

Well-designed sun control and shading devices are proposed to reduce building peak heat gain

and cooling requirements and improve the natural lighting quality of building interiors (Please

refer figure below).

The design of shading devices will include simple fixed overhangs which are very effective at

shading south-facing windows in the summer when sun angles are high.



47

The other shading devices which have been explored are as given below:

Movable opaque: Roller blind curtains, awnings etc. reduce solar gains but impede air

movement and cut the view.

Louvers: They are adjustable or can be fixed. To a certain extent impede air movement

and provide shade to the building from the solar radiation.

9.7 Do the structures use energy-efficient space conditioning, lightening and mechanical

systems? Provide technical details. Provide details of the transformers and motor

efficiencies, lightening intensity and air conditioning load assumption? Are you using CFC

and HCFC free chillers? Provide specifications.

Yes. The walls and rooms are insulated such that air conditioning load is reduced. Well designed

building structures will allow natural light to enter. Measures prescribed in Energy Conservation

Building Code 2017 have been adopted to reduce the heat influx by walls, roofs and openings.

Only prescribed quality of glasses has been used.

9.8 What are the likely effects of the building activity in altering the micro-climates?

Provide a self assessment on likely impacts of the proposed construction on creation of heat

island & inversion effects?

Heat emissions from the construction may be from the following sources:



48

emissivity and thermal characteristics.

The project being a Group Housing Project involved use of glass as wall material. All fenestration

with U-factors, SHGC, or visible light transmittance determined, certified and labeled in

accordance ISO 15099 shall be adopted.



50

9.12 What is the rate of air infiltration in to the building? Provide details of how you are

mitigating the effects of infiltration.

The Group Housing Project will not be centrally air conditioned and hence there will be provision

for ample natural ventilation.

9.13 To what extent the non–conventional energy technologies are utilized in the overall

energy consumption? Provide details of the renewable energy technologies used.

Solar energy will be variedly used as:

Solar street lights.

Roof top SPV (Solar Photo voltaic) systems with or without grid interaction.

LEDs will be used in buildings to minimize the energy consumption.

Green area will cause natural cooling and will reduce the load on conventional

energy resources.

10. ENVIRONMENT MANAGEMENT PLAN

The Environment Management Plan (EMP) would consist of all mitigation measures for each

component of the environment due to the activities increased during the construction, operation

and the entire life cycle to minimize adverse environmental impacts resulting from the activities

of the project. It would also delineate the environmental monitoring plan for compliance of

various environmental regulations. It will state the steps to be taken in case of emergency such as

accidents at the sites including fire. The detailed EMP for the Group Housing Project is given

below.

10.1 Environmental Management Plan

The Environment Management Plan (EMP) is a site specific plan developed to ensure that the

project is implemented in an environmental sustainable manner where all contractors and

subcontractors, including consultants, understand the potential environmental risks arising from

the Group Housing Project and take appropriate actions to properly manage that risk. EMP also

ensures that the project implementation is carried out in accordance with the design by taking



51

appropriate mitigation actions to reduce adverse environmental impacts during its life cycle. The

plan outlines existing and potential problems that may adversely impact the environment and

recommends corrective measures where required. Also, the plan outlines roles and responsibility

of the key personnel and contractors who will be in-charge of the responsibilities to manage the

Group Housing Project site.

10.1.1 The EMP is generally

Prepared in accordance with rules and requirements of the MoEF & CC and CPCB/ SPCB

To ensure that the component of facility are operated in accordance with the design

A process that confirms proper operation through supervision and monitoring

A system that addresses public complaints during construction and operation of the

facilities and

A plan that ensures remedial measures is implemented immediately.

The key benefits of the EMP are that it offers means of managing its environmental performance

thereby allowing it to contribute to improved environmental quality. The other benefits include

cost control and improved relations with the stakeholders.

EMP includes four major elements:

Commitment & Policy: The management will strive to provide and implement the

Environmental Management Plan that incorporates all issues related to air, water, land and

noise.

Planning: This includes identification of environmental impacts, legal requirements and

setting environmental objectives.

Implementation: This comprises of resources available to the developers, accountability of

contractors, training of operational staff associated with environmental control facilities

and documentation of measures to be taken.

Measurement & Evaluation: This includes monitoring, counteractive actions and record

keeping.



52

It is suggested that as part of the EMP, a monitoring committee would be formed by M/s Raheja

Design & Contracts Ltd. comprising of the site in-charge/coordinator, environmental group

representative and project implementation team representative. The committee’s role would be to

ensure proper operation and management of the EMP including the regulatory compliance.

The components of the environmental management plan, potential impacts arising, out of the

project and remediation measures are summarized below in Table 12.

10.2 ENVIRONMENT MANAGEMENT PLAN

An Environmental Management Plan (EMP) have been required to mitigate the predicted

adverse environmental impacts during construction and operation phase of the Group

Housing Project and these are discussed in later subsections.

10.2.1 EMP for Air Environment

Construction Phase

To mitigate the impacts of PM during the construction phase of the Group Housing

Project , the following measures are implemented:

A dust control plan

Procedural changes to construction activities

Dust Control Plan

The most cost-effective dust suppressant is water because water is easily available on

construction site. Water was applied using water trucks, handled sprayers and automatic

sprinkler systems. Furthermore, incoming loads could be covered to avoid loss of

material in transport, especially if material is transported off-site and same will be done

for the further construction.

Procedural Changes to Construction Activities

Idle time reduction: Construction equipment is commonly left idle while the operators

are on break or waiting for the completion of another task. Emission from idle equipment

tends to be high, since catalytic converters cools down, thus reducing the efficiency of

hydrocarbon and carbon monoxide oxidation. Existing idle control technologies

comprises of power saving mode, which automatically off the engine at preset time and

reduces emissions, without intervention from the operators.

Improved Maintenance: Significant emission reductions can be achieved through

regular equipment maintenance. Contractors will be asked to provide maintenance

records for their fleet as part of the contract bid, and at regular intervals throughout the



69

life of the contract. Incentive provisions will be established to encourage contractors to

comply with regular maintenance requirements.

Reduction of On-Site Construction Time: Rapid on-site construction would reduce the

duration of traffic interference and therefore, will reduce emissions from traffic delay.

Operation Phase

To mitigate the impacts of pollutants from DG set and vehicular traffic during the

operational phase of the Colony, following measures are recommended for

implementation:

DG set emission control measures

Vehicular emission controls and alternatives

Greenbelt development

Diesel Generator Set Emission Control Measures

Adequate stack height will be maintained to disperse the air pollutants generated from the

operation of DG set to dilute the pollutants concentration within the immediate vicinity.

Hence no additional emission control measures have been suggested.

Vehicle Emission Controls and Alternatives

During construction, vehicles were properly maintained to reduce emission. As it is a

Group Housing Project , vehicles weree generally having “PUC” certificate.

Footpaths and Pedestrian ways: Adequate footpaths and pedestrian ways would be

provided at the site to encourage non-polluting methods of transportation.

Greenbelt Development

Increased vegetation in the form of greenbelt is one of the preferred methods to mitigate

air and noise pollution. Plants serve as a sink for pollutants, act as a barrier to break the

wind speed as well as allow the dust and other particulates to settle on the leaves. It also



70

helps to reduce the noise level at large extent. The following table indicates various

species of the greenbelt that can be used to act as a barrier.

10.2.2 EMP FOR NOISE ENVIRONMENT

Construction Phase

To mitigate the impacts of noise from construction equipment during the construction

phase on the site, the following measures are implemented.

Time of Operation: Noisy construction equipment has not been allowed to use at night.

Job Rotation and Hearing Protection: Workers employed in high noise areas are

employed on shift basis. Hearing protection such as earplugs/muffs has been provided to

those working very close to the noise generating machinery the same implementations

were incorporated for the further construction.

Operation Phase

To mitigate the impacts of noise from diesel generator set during operational phase, the

following measures are recommended:

Adoption of Noise emission control technologies

Greenbelt development

Noise Emission Control Technologies

The DG set room will be provided with acoustic enclosure to have minimum 25 d B (A)

insertion loss or for meeting the ambient noise standard whichever is on higher side as

per E (P) Act, GSR 371 (E) and its amendments. It would be ensured that the

manufacturer provides acoustic enclosure as an integral part along with the diesel

generators set. Further, enclosure of the services area with 4 m high wall will reduce

noise levels and ensure that noise is at a permissible limit for resident of the site and

surrounding receptors.

10.2.3 EMP FOR WATER ENVIRONMENT

Construction Phase

To prevent degradation and to maintain the quality of the water source, adequate control

measures have been taken. To check the surface run-off as well as uncontrolled flow of

water into any water body check dams with silt basins are planned. The following

management measures are taken to protect the water source being polluted during the

construction phase:

Avoid excavation during monsoon season

Care has been taken to avoid soil erosion

Mobile toilets has been constructed on site during construction phase and the

Wastewater is channelized to the septic tanks in order to prevent Wastewater to enter into

the water bodies

Any area with loose debris within the site has been planted

To prevent surface and ground water contamination by oil and grease, leak-proof

containers have been used for storage and transportation of oil and grease. The floors of

oil and grease handling area are being kept effectively impervious. Any wash off from

the oil and grease handling area or workshop is being drained through imperious drains

Collection and settling of storm water, prohibition of equipment wash downs and

prevention of soil loss and toxic release from the construction site are necessary measure

to be taken to minimize water pollution

All stacking and loading area has been provided with proper garland drains,

equipped with baffles, to prevent run off from the site, to enter into any water body. The

above steps had been complied for the further construction phase

Operation Phase

In the operation phase of the project, water conservation and development measures will

be taken, including all possible potential for rain water harvesting. Following measures

will be adopted:

Water source development.



72

Minimizing water consumption.

Promoting reuse of water after treatment and development of closed loop

systems for different water streams.

Water Source Development

Water source development shall be practiced by installation of scientifically designed

Rain Water Harvesting system. Rainwater harvesting promotes self-sufficiency and

fosters an appreciation for water as a resource.

Minimizing Water Consumption

Consumption of fresh water will be minimized by combination of water saving devices

and other domestic water conservation measures. Further, to ensure ongoing water

conservation, an awareness program will be introduced for the residents. The following

section discusses the specific measures, which shall be implemented:

Domestic and Group Housing Usage

Use of water efficient plumbing fixtures (ultra flow toilets and urinals, low

flow sinks, water efficient dishwashers and washing machines). Water efficient plumbing

fixtures uses less water with no marked reduction in quality and service

Leak detection and repair techniques.

Sweep with a broom and pan where possible, rather than hose down for external

areas.

Meter water usage: Implies measurement and verification methods.

Monitoring of water uses is a precursor for management.

Horticulture

Drip irrigation system shall be used for the lawns and other green area. Drip

irrigation can save 15-40% of the water, compared with other watering techniques.



73

Plants with similar water requirements shall be grouped on common zones to

match precipitation heads and emitters.

Use of low-angle sprinklers for lawn areas.

Select controllers with adjustable watering schedules and moisture sensors to

account for seasonal variations and calibrate them during commissioning.

Place 3 to 5 inches of mulch on planting beds to minimize evaporation.

Promoting Reuse of Water after Treatment and Development of Closed Loop

Systems

To promote reuse of Wastewater and development of closed loop system for Wastewater

segregation. Two water conservation schemes are suggested, namely:

1) Storm Water Harvest 2) Wastewater recycling.

Storm water harvest as discussed in earlier, will be utilized for artificial recharge of

ground water sources; and Wastewater will be reused on site after treatment.

Wastewater Treatment Scheme

Proponent will treat the Wastewater of the Group Housing Project in well-designed

sewage treatment plant of capacity 100 KLD based on SBR technology.

Storm Water Management

Most of the storm water produced on site will be harvested for ground water recharge.

Thus proper management of this resource is a must to ensure that it is free from

contamination.

Contamination of Strom Water is possible from the following sources:

Diesel and oil spills in the diesel power generator and fuel storage area

Waste spills in the solid / hazardous waste storage area

Oil spills and leaks in vehicle parking lots



74

Silts from soil erosion in gardens

Spillage of sludge from sludge drying area of sewage treatment plant

A detailed storm water management plan will be developed which will consider the

possible impacts from above sources. The plan will incorporate best management

practices which will include following:

Regular inspection and cleaning of storm drains

Clarifiers or oil/separators will be installed in all the parking areas. Oil / grease

separators installed around parking areas and garages will be sized according to

peak flow guidelines. Both clarifiers and oil/water separators will be periodically

pumped in order to keep discharges within limits

Covered waste storage areas

Avoid application of pesticides and herbicides before wet season

Secondary containment and dykes in fuel/oil storage facilities

Conducting routine inspection to ensure cleanliness

Provision of slit traps in storm water drains

Good housekeeping in the above areas

10.2.4 EMP FOR LAND ENVIRONMENT

Construction Phase

The waste generated from construction activity includes construction debris, biomass

from land clearing activities, waste from the temporary make shift tents for the labors and

hazardous waste. Following section discuss the management of each type of waste.

Besides waste generation, management of the topsoil is an important area for which

management measures are required.



75

Construction Debris

Construction debris is bulky and heavy and re-utilization and recycling is an important

strategy for management of such waste. As concrete and masonry constitute the majority

of waste generated, recycling of this waste by conversion to aggregate can offer benefits

of reduced landfill space and reduced extraction of raw material for new construction

activity. This is particularly applicable to the Group Housing Project site as the

construction is to be completed in a phased manner.

Mixed debris with high gypsum, plaster, not been used as fill, as they are highly

susceptible to contamination, and has been send to designated solid waste landfill site.

Metal scrap from structural steel, piping, concrete reinforcement and sheet metal work

has been removed from the site by construction contractors. A significant portion of

wood scrap is being reused on site. Recyclable wastes such as plastics, glass fiber

insulation, roofing etc. is being sold to recyclers.

Hazardous waste

Construction sites are sources of many toxic substances such as paints, solvents wood

preservatives, pesticides, adhesives and sealants. Hazardous waste generated during

construction phase shall be stored in sealed containers and disposed off as per The

Hazardous Wastes (Management & Handling) Rules, 1998.

Some management practices to be developed are:

Herbicides and pesticide has not been over applied (small-scale

applications) and not applied prior to rain

Paintbrushes and equipment for water and oil based paints is being

cleaned within a contained area and has not been allowed to contaminate

site soils, water courses or drainage systems

Provision of adequate hazardous waste storage facilities. Hazardous waste

collection containers are located as per safety norms and designated

hazardous waste storage areas is away from storm drains or watercourses



76

Segregation of potentially hazardous waste from non-hazardous

construction site debris

Well labeled all hazardous waste containers with the waste being stored

and the date of generation

Instruct employees and subcontractors in identification of hazardous and

solid waste

Even with careful management, some of these substances are released into air, soil and

water and many are hazardous to workers. With these reasons, the best choice is to avoid

their use as much as possible by using low-toxicity substitutes and low VOC (Volatile

Organic Compound) materials.

Waste from Temporary Makes Shift Tents for Labors

Wastes generated from temporary make shift labor tents are mainly comprise of

household domestic waste, which is being managed by the contractor of the site. The

wastewater generated is being channelized to the septic tank.

Top Soil Management

To minimize disruption of soil and for conservation of top soil, the contractor has kept

the top soil cover separately and stockpiles it. After the construction activity is over, top

soil will be utilized for landscaping activity. Other measures, which would be followed to

prevent soil erosion and contamination include:

Maximize use of organic fertilizer for landscaping and green belt

development

To prevent soil contamination by oil/grease, leaf proof containers would

be used for storage and transportation of oil/grease and wash off from the

oil/grease handling area shall be drained through impervious drains and

treated appropriately before disposal

Removal of as little vegetation as possible during the development and re-

vegetation of bare areas after the project.



77

Working in a small area at a point of time (phase wise construction)

Construction of erosion prevention troughs/berms.

The same steps will be taken for the remaining construction phase.

Operational Phase

The philosophy of solid waste management at the Group Housing Project will be to

encouraging the four R’s of waste i.e. Reduction, Reuse, Recycling and Recovery

(materials & energy). Regular public awareness meetings will be conducted to involve

the staff for the proper segregation and storage techniques. 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 and transportation, treatment or

disposal and closure and post-closure care of treatment/disposal facility.

Collection and Transportation

During the collection stage, the solid waste of the Group Housing Project

will be segregated into biodegradable waste and non-biodegradable.

Biodegradable waste and non biodegradable waste will be collected in

separate bins. Biodegradable waste will be treated in the project premises

by organic converter. The recyclable wastes will be sent off to recyclabers.

Proper guidelines for segregation, collection and storage will be prepared

as per SWM Rules, 2016 and amended Rules, 2008.

To minimize littering and odour, 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.



78

Figure 5: Waste Management Flow Diagram

Disposal

With regards to the disposal/treatment of waste, the management will take the services of

the authorized agency for waste management and disposal of the same on the project site

during its operational phase.

10.2.5 EMP FOR ECOLOGICAL ENVIRONMENT

Construction activity changes the natural environment. But a Group Housing Project also

creates a built environment for its inhabitants. The project requires the implementation of

following choices exclusively or in combination.

Construction Stage

Restriction of construction activities to defined project areas, which are

ecologically sensitive



79

Restrictions on location of temporary labor tents and offices for project staff

near the project area to avoid human induced secondary additional impacts on

the flora and fauna species

Cutting, uprooting, coppicing of trees or small trees if present in and around

the project site for cooking, burning or heating purposes by the labors has

been prohibited and suitable alternatives for this purpose is being made

Along with the construction work, the peripheral green belt has been

developed with suggested native plant species, as they will grow to a full-

fledged covered at the time of completion.

Operation Stage

Improvement of the current ecology of the Group Housing Project site will entail the

following measures:

Plantation and Landscaping

Avenue Plantation Development

Park and Avenue Plantation

The section below summarizes the techniques to be applied to achieve the above

objectives:

Plantation and landscaping

Selection of the plant species would be done on the basis of their adaptability to the

existing geographical conditions and the vegetation composition of the forest type of the

region earlier found or currently observed.

Avenue Plantation Development Plan

The plantation matrix adopted for the green belt development includes pit of 0.3 m × 0.3

m size with a spacing of 2 m x 2 m. In addition, earth filling and manure may also be

required for the proper nutritional balance and nourishment of the sapling. It is also

recommended that the plantation has to be taken up randomly and the landscaping

aspects could be taken into consideration.



80

Plantation comprising of medium height trees (7 m to 10 m) and shrubs (5 m height) are

planned for the green belt. In addition creepers will be planted along the boundary wall to

enhance its insulation capacity.

Selection of Plant Species for Green Belt Development

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

climate, elevation and soil. The plants would exhibit the following desirable

characteristics in order to be selected for plantation

1. The species should be fast growing and providing optimum penetrability

2. The species should be wind-firm and deep rooted

3. The species should form a dense canopy

4. As far as possible, the species should be indigenous and locally available

5. Species tolerance to air pollutants like SO2 and NO2 should be preferred

6. The species should be permeable to help create air turbulence and mixing within

the belt

7. There should be no large gaps for the air to spill through

8. Trees with high foliage density, leaves with larger leaf area and hairy on both the

surfaces

9. Ability to withstand conditions like inundation and drought

10. Soil improving plants (Nitrogen fixing rapidly decomposable leaf litter)

11. Attractive appearance with good flowering and fruit bearing

12. Bird and insect attracting tree species

13. Sustainable green cover with minimal maintenance.

Parks and Avenue Plantation

Parks and gardens maintained for recreational and ornamental purposes will not

only improve the quality of existing ecology at the Group Housing Project site but

also will improve the aesthetic value.



81

Avenue Plantation

1. Trees with colonial canopy with attractive flowering

2. Trees with branching at 7 feet and above

3. Trees with medium spreading branches to avoid obstruction to the traffic

4. Fruit trees to be avoided because children may obstruct traffic and general

movement of public

10.2.6 EMP for Socio-Economic Environment

The social management plan has been designed to take proactive steps and adopt best

practices, which are sensitive to the socio-cultural setting of the region. The Social

Management Plan for Group Housing Project focuses on the following components:

Income Generation Opportunity during Construction and Operation Phase

The Group Housing Project has been providing employment opportunity during

construction phase and will provide in operation phase also. There is also be a

wide economic impact in terms of generating opportunities for secondary

occupation within and around the colony. The main principles considered for

employment and income generation opportunities are out lined below:

Employment strategy is providing preferential employment of local people

Conditions of employment would address issues like minimum wages and

medical care for the workers. Contractors would be required to abide to

employment priority towards locals and abide by the labor laws regarding

standards on employee terms and conditions.

Improved Working Environment for Employees

The Group Housing Project is providing safe and improved working conditions

for the workers employed at the facility during construction and operation phase.

With the proposed ambience and facilities provided, the colony will provide a

new experience in living and recreations. Following measures would be taken to

improve the working environment of the area:



82

Less use of chemicals and biological agents with hazard potential

Developing a proper interface between the work and the human resource

through a system of skill improvement

Provision of facilities for nature care and recreation e.g. indoor games

facilities

Measures to reduce the incidence of work related injuries, fatalities and

diseases

Maintenance and beautifications of the colony and the surrounding roads

10.2.7 EMP FOR ENERGY CONSERVATION

Energy conservation program has been implemented through measures taken both on

energy demand and supply.

Energy conservation is one of the main focuses during the colony planning and operation

stages. The conservation efforts consist of the following:

Architectural design

Maximum utilization of solar light has been done.

Maximize the use of natural lighting through design.

Supply Energy Conservation Demand

Utilize energy-efficient diesel genetators

Exploring the possibilities of introducing renewable energy

Reduce consumption Use energy efficient appliances Create Guest Awareness



83

The orientation of the buildings has been done in such a way that maximum

daylight is available.

The green areas are spaced, so that a significant reduction in the temperature can

take place. Same steps will be taken for the remaining construction phase.

Energy Saving Practices

Energy efficient lamps will be provided within the colony.

Constant monitoring of energy consumption and defining targets for energy

conservation.

Adjusting the settings and illumination levels to ensure minimum energy used for

desired comfort levels.

c. Treatment Technology

Sequence Batch Reactor is a most prominent technique for removing organic carbon and

nutrient in a relatively short period. The fill and draw scheme constitute the basic principle of

the SBR system. Raw sewage will be collected under gravity into the equalization tank after

allowing to pass through the bar screen. The bar screen, by removing coarse solids from the

sewage help in protecting the raw sewage pump. The raw sewage equalization tank, through

temporarily holding the incoming sewage facilitates both pumping of sewage through the STP



and dampening the flow variation in the received sewage. The sewage collected in

equalization tank is pumped and passed through the SBR tank. 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.

The SBR is basically a single tank that serves both biological reactor and settler in a temporal

sequence, whereas aeration and settling are simultaneous but in a spatial sequence.

From the reactors, the suspended solids will settle at the bottom of the tank & clear

supernatant will overflow to Collection cum storage tank collected sludge at bottom shall 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 and activated carbon filter 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 shall be provided in this tank to avoid conversion into anaerobic

conditions, thickening of sludge and keep sludge in homogenous condition. The digested &

thickened sludge shall be further thickened through Sludge Dewatering System and disposed

of periodically through closed tanker or can be reused as manure.

Stages of Treatment: The treatment process consists of the following stages:

Equalization

Bio- Degradation

Clarification & Settling

adjacent drain by a pipe through catch basins. Therefore it has been proposed to provide 2

rainwater harvesting pits at selected locations which will catch the entire run-off from the site.

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 40 mm/hr. shall 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 40 mm/hr. The recharge pit is constructed for recharging

the water. The recharge pits of 3 m dia and 3.5 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 15 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 (Existing + Expansion):

Roof-top area = Ground Coverage = 1727.06 m2

Green Area = 1,065 m2

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

= 7100 - (1727.06 + 1,065) = 4,307.94m2

Runoff Load

Roof-top Area = 1,727.06 × 0.04 × 0.8

= 55.265 m3/hr

Green Area = 1,065 × 0.04 × 0.1

= 4.26 m3/hr

Paved Area = 4,307.94 × 0.04 × 0.7

= 120.62 m3/hr

Total Runoff Load = (55.265 + 4.26 + 120.62) m3/hr

= 180.145 m3/hr

Taking 15 minutes Retention Time, Total volume of storm water = 180.145 /4

= 45.03 m3

Taking the effective diameter and depth of a Recharge pit 1.5 m and 3.5 m respectively, Volume

of a single Recharge pit = πr2h =3.14 x 1.5 x 1.5 x 3.5 = 24.75 m3

Hence No. of pits required = 45.03 /24.75 = 1.81 pits or 2 Pit

Therefore, a total of 2 Rain Water Harvesting pits are proposed within the project

premises for artificial ground water recharge.

A. INTRODUCTION

In recent decades, many environmental problems have increased as the result of human

activities and unplanned management of the technological development those interference

ecosystems which lead the ecological damages/environmental degradation. Therefore, a

dispute between the importance of conservation and preservation of ecosystems to protect

environment and the necessity to satisfy human desire by sacrifice the environment has been

arise across the world.

Ecological damages/Environmental degradation occurs when Earth’s natural resources are

depleted and environment is compromised in the form of extinction of species, pollution in air,

water and soil, damage to biodiversity and rapid growth in population.

Environmental degradation is one of the largest threats to the world today. For the sustainable

development it is important to conserve and protect our environment from the further

degradation. Also, minimize the deterioration of the all the components of environment such

as air, water, soil and biota (Flora and fauna- terrestrial and aquatic).

Various human activities have induced many undesirable effects to the environment which can

be threatening human health, economic, natural resources. It would be our prime duty to take

care of environmental concerns thus making it more useful and protected for us and future

generations.

Development is a necessity for the people of a developing country especially like India along

with conservation and protection of the environment and its components. Human development

is necessary for developing human life. Human development always emphasizes more on

social justice than economic growth. It reduces the discrimination between different social

communities. The ecological stability of human settlements is part of the relationship between

humans and their natural, social and built environments.

DAMAGE ASSESSMENT REPORT

This is a Residential Project at Village Dholai, Sanganer, Jaipur, Rajasthan of M/s Raheja Design & Contracts Ltd.

We have completed the construction of the project as per the Building Plans approved by

JDA. The total Constructed area of the project is 25,368.49Sq.m. ,

MoEF&CC, GoI issued a recent Notification vide S.O. 804 (E), dated 14.03.2017, for one

time opportunity for Violation matters. Therefore, we are hereby submitting our application

for getting Environmental Clearance of the project as per EIA Notification dated 14.09.2006 as

amended on 14.03.2017.

The partly construction work has already been done at the project site, which was allotted by

JDA. The area adjacent to the project is under development plan. The project activities have

been confined within the project in the site only and the likely impacts on land-use,

Residential facilities and open space is very meager. The project does not have any

adverse impact on the surrounding environment. Instead, the development of residential

Colony in this area will increase the residential facility in the area and direct & indirect employment opportunities. There was no major disturbance to local ecology as no tree was cut for development, trees have been retain and will pert of green area.; the project has a proposal of green area development, which will increase the aesthetic value of the area. Total Green area development will be done on 1,065 sq. m (15 % of plot area). The indigenous / local plants will be planted all around the periphery of the project area and along the roadside & lawn.

The project activities have not affected surroundings & any significant land disturbance resulting

in soil erosion, subsidence and instability. The area is not susceptible to erosion. The

excavated earth materials have been utilized at the site for leveling, backfilling and

landscaping/green area development.

This is building construction project on vacant land so no demolition work was carried out.

Land/soil environment was temporarily affected due to activities like site preparation,

excavation, material handling & storage etc. during construction phase. Proper drainage

systems have been provided to deal with the storm water in case of rain.

The ground surface of the project is almost level. The project is not likely to alter or obstruct any

natural drainage courses. There is no natural watercourse passing through the project site.

Hence the project does not involve alteration of natural drainage systems. As a result of

excavation of topsoil during construction phase, the impact on drainage pattern, and run off

characteristics have been restricted to the small area. Proper rain water drainage facility will

be provided and the run-off generated will be used for recharging the ground water level.

Excavation was carried out for foundation of building & construction of basement. The

total soil generated was used at the site itself for the purpose of Site development,

landscaping and Green area development.

The waste generated during construction activities is limited to project site only and during

construction phase only. These were reused for backfilling and road development

after manual segregation. These wastes have been utilized for construction of roads.

Conclusively, it can be stated that impacts may be confined to small area (mainly to project

site) and for short duration. Mitigation plan suggests maximum re-use of construction waste

on site, removal of non-reusable waste from the site and its proper disposal, which would

reduce the impact significantly.

The incremental pollution load from waste water generated from the project activity

generated from the project & whole treated water will used in the project premises. There will

be a dual plumbing system for use of water with different water quality namely Municipal

Supply Water/Ground water and Recycled Water which will result in optimal use of water

for different applications thus saving on the high quality water. Installation of dual plumbing

for using recycled water will save the potable water from municipal supply or ground water.

Small quantity of fugitive emission is envisaged during transport and handling of

construction material. Such emission will be temporary and controlled by providing water

sprinkling and other viable technique.

The machinery which has been used for construction was of high standard and adhered to

international standard. These standards itself take care of noise pollution control / vibration

control and air emission control. Hence insignificant impacts due to construction

machinery are envisaged. Apart from this, the construction activities were restricted to

daytime only, same provision will be made for the rest of the construction.

Thus, we can say that no major damage is done by this Residential Project at Village Dholai,

Sanganer, Jaipur, Rajasthan.

AUGMENTATION PLAN

ENVIRONMENTAL MANAGEMENT PLAN DURING CONSTRUCTION PHASE:

LAND USE-LAND COVER

The land of the project with surroundings was flat land without any undulation. Moreover, it

was used as a private land earlier; hence any significant land disturbances resulting in soil

erosion, subsidence and instability did not occur.

SOIL

Land/soil environment were temporarily affected due to activities like site preparation,

excavation, material handling & storage etc. during construction phase, however after the

initial phase, the site was levelled back to its original level.

DRAINAGE

There is no natural watercourse or drainage passing through the project site. Hence the project

did not involve alteration of natural drainage systems. Proper drainage systems are provided to

deal with the storm water in case of rain.

ECOLOGY (FLORA AND FAUNA)

There was no major vegetation in the project site. So, permanent habitat of any fauna did not

exist in the project site. Hence, for development of the project no any tree was demolished. No

major disturbance to local ecology occurred.

WATER POLLUTION

Sewage generated during construction phase is being discharged into soak pit through septic

tank. Wastewater generated due to washing and cleaning of construction equipment is collected

and reused in concrete handling, mixing & curing.

AIR POLLUTION

Air pollution during construction activity is mainly due to dust generation and gaseous

emission from vehicular movement and to control air pollution following precautionary

measures were undertaken:

Peripheral barricading sheet of minimum 4 m heights to prevent dust emission

spreading outside the project premises.

Under construction building is being covered thoroughly with jute/green PVC cloth.

Avoiding vehicle trips carrying construction material during day time and peak hour

Used Plastic cover sheet / tarpaulin while transporting raw material at site.

Store any dry, dusty materials in closed room/shed and prevented from blowing.

Sprinkled water with fine spray nozzles in vulnerable areas to suppress the dust and

control fugitive emissions generated due to transport and handling of construction

material.

SOLID WASTE

This building construction project was setup on a vacant land therefore no demolition work was

carried out. Hence, there was no demolition waste generation during construction phase. For

construction of the project excavation was carried out for foundation and basement of the

building. Top soil was used for greenbelt development and other excavated soil was used at site

for back filling & land leveling.

The solid waste generated during construction activities was limited to project site only. These

are segregated manually to remove non-reusable waste and reusable waste was reused for

backfilling and road development within the site up to the maximum possible extent. The non-

reusable waste is disposed of by sending at approved sites of respective area.

NOISE POLLUTION

Noise has been generated from various construction activities. To control noise pollution

following precautionary measures were undertaken:

Use of machineries having highest standard and comply with national standard that take

care of noise and vibration.

Carrying out oiling and lubrication of equipment
