1.3. What are the likely impacts of the proposed activity on the existing facilities adjacent to

the proposed site? (Such as open spaces, community facilities, details of the existing land

use, disturbance to the local ecology).

Impact on Land use pattern

The project will be established on designated area. And there will be no displacement or

resettlement of people from the acquired land. The land is not a forestland and no tree will be

uprooted. Therefore, the predicted impacts on the land use pattern of site will be

insignificant.

Impact on ecological setting

The impact due to construction activities on the ecology of the area will be confined to the

construction site itself. There will be negligible impact on the ecology (flora & fauna) during

the construction phase. As there is no forest in and around the proposed site, no impact is

anticipated on the fauna. However, no adverse impact is anticipated on the ecology due to the

proposed Housing complex.

No significant air pollutants air emissions will be discharged from the project. Therefore,

there will be insignificant impacts on the flora and fauna due to the operation of the project.

There will be very little SP M, SO2 and NOX emission from the proposed Housing activity.

The entire project influenced area will be developed as per the Master Plan Delhi

Development Authority, thus no induced development is foreseen due to the proposed

project. Also the proposed development shall be carried out as per the defined building by-

laws; hence no impacts are envisaged due to proposed development.

Moreover, proposed project will be provide value addition to the existing infrastructure

facilities such as improve public transportation system, telecommunications, power lines,

better roads security etc.

Further, during the construction as well as operation stage of the project, will generate direct

and indirect employment opportunities for a large section of society. The employment will

have positive impact thereby increasing the quality of life.

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).

Soil Type:

In order to understand the existing scenario of soil quality in the study area of project site,

Soil sample were collected from project site based on the collected Soil Map for the area,

Existing Land use of the Area, sources of pollution etc. Samples were taken from one

location based on the above said criteria. The baseline concentrations of important

parameters like organic matter, nitrogen content and phosphate etc. indicate that soil in the

study area has good productivity potential and sandy silt in texture.

Slope Analysis: The project area possesses fairy plain terrain with drainage slope towards South-Eastern side

of the project site.

Total Station Survey was carried out not only for project site but also surrounding area.

Erosion / Subsidence:

Proper greening & paving of area will not cause any soil erosion problem and subsidence.

Seismicity:

The area under study falls in Zone-IV according to the Indian standard Seismic Zoning Map.

Suitable seismic coefficients in horizontal and vertical directions respectively, have to be

adopted while designing the structures.

1.5. Will the proposal involve alteration of natural drainage systems? (Give details on a

contour map showing the natural drainage near the proposed project site)

The proposed project activities will not cause any alteration of natural drainage system.

1.6. What are the quantities of earthwork involved in the construction activity-cutting, filling

reclamation etc. (Give details of the quantities of earthwork involved, transport of fill

materials from outside the site etc.)

During construction phase, some excavation is envisaged in order to provide foundations and

basement. This excavated soil (app. 79320.9 m3) will be properly stacked within the site

under tarpaulin cover; and will be reused for backfilling purpose, road construction etc. The

top-soil will be preserved separately and will be used for landscaping purpose only. Hence no

immediate adverse impacts on the land environment are envisaged.

1.7. Give details regarding water supply, waste handling etc during the construction period.

Water Supply

During the construction stage, water will be sourced primarily through tankers arranged by

the contractor and partly through bore wells only if D J B permits for the same.

Waste Generation / Handling

Soil excavated will be reused for backfilling and the fertile top soil will be reused for

horticultural purpose. Spillage of oil from the machinery or cement residual from concrete

mixer plants will be properly collected and disposed off. For construction laborers, proper

sanitary facilities & wash areas will be constructed and good hygienic conditions will be

maintained.

1.8. Will the low lying areas & wetlands get altered? (Provide details of how low lying and

Wet lands are getting modified from the proposed activity)

No Low lying and wetlands areas are present in and around the project site.

1.9. Whether construction debris & waste during construction cause health hazard? (Give

quantities of various types of wastes generated during construction including the construction

labour and the means of disposal)

Construction and pre-operational cleaning of the proposed facility would generate limited

amounts of some waste solvents and flushing materials. A licensed contractor would remove

these materials for appropriate off-site disposal as discussed below The hazardous / non

hazardous waste shall be subjected to proper segregation, reuse / recycle, disposal and proper

documentation.

Solid waste and debris that cannot be recycled, reused, or salvaged would be stored in on site

dumpsters or similar containers for disposal. Potentially hazardous wastes would be

separated from normal waste including segregation of storage. All waste from the project site

would be removed in accordance with applicable regulatory requirements.

During construction, all chemical materials would be evaluated during the material receiving

process. Materials that are hazardous would be stored in identified storage areas that include

containment measures. Personal would be rained on the proper use, handling, protective

equipment, storage, and disposal of hazardous materials. A health and Safety Plan would be

developed and implemented to insure that the potential for exposure of construction workers,

workers on near by sites, and others in the area is minimized. The health and safety plan

would define worker safety training, monitoring procedures, and personal protective

measures. The construction phase would require use of various petroleum and chemical

products, including medium- weight oil, thinners, solvents, paint, gasoline and diesel.

The hazardous Waste is stored in leak proof container (s) and able to drain / remove liquids,

and the containers are duly marked with “Hazardous Waste “in red colouran with date of

beginning of storage on each containers. These Hazardous Waste containers are stored on

pucca floor in an isolated covered area in the unit in such a manner that it does not in any

way contaminate the environment or the ground water due to air/rain/ seepage/ leakage etc.

That storage facility is having appropriate containment system. Care will be taken

precautions to prevent any accidental ignition or reaction of ignitable or reactive waste.

The construction debris generated from the construction project will be common place in

nature and will not cause any health hazard to associate and nearby population. The

construction debris will be used for land leveling / backfilling and landscaping according to

its composition.. Waste concrete will be reused as aggregate in construction process. Total

construction waste general is estimated as following: -

storm water from terraces and other open areas will be collected through rainwater down take

pipes and connected to nearest deep drain with 100-200 mmdia pipes. The rain water will be

collected by catch manholes with minimum depth of 600 mm and slope of 1:350 towards

main drain with 300 mmdia PVC pipes and PCC cover. Open drains with perforated RCC

cover will be places at every 3 m interval. The channels will lead to approx. 13 nos. rain

water harvesting pits, located at different locations around the premises. The size of rain

water harvesting pits is 5x53m with desilting chamber 1.5x3m with 5 m effective depth. The

pits will be laid with 500 mm thick layer of 1.5-2.0 mm average dia coarse sand, over 500

mm thick layer of 5-10 mm dia gravels, which, in turn will be laid on 500 mm thick layer of

10-30 mmdia loose boulders. A perforated PVC pipe, laid inside bore; will transfer the

excess rain water to sandy layer. Casing will be provided with cleansed pea gravel of 3-6 mm

average dia. The run-off from roads and parking area is provided with oil & grease trap

system.

For collecting storm water, storm water drainage network has been provided during the

design stage as per the guidelines defined in Master Plan of Delhi City. In the project design,

it shall be ensured that no mixing of the storm water with waste effluent takes place. All the

storm water will be diverted to rain water – harvesting pits proposed in the complex. Roof

rain water harvesting potential for the proposed project site is 264.63m3/hr. The excess rain

water is disposed to the municipal storm water line as per the site condition. Diagram of

typical rainy well is shown below:

2.8. 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?

No adverse impacts are envisaged due to proposed project on the runoff characteristics of the

area as adequate arrangements will be made to trap & treat the rainwater and suitable storm

water drainage system will be provided.

During the post-construction phase, runoff from the project shall not be allowed to stand or

enter into the roadside or nearby drain. Adequate measures (as discussed in Clause 2.7) shall

be take to collect such runoff and either shall be reused or stored in recharging pits suitable

garlanding drain as per the existing contours of the pot will be developed.

2.9. 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):

As detailed out in Clauses 2.2, 2.3 and 2.5.

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)

The best way of minimizing sediment loss from a construction site is to control the erosion in

the first place. Sediment control measures that capture eroded soil (for example, hay bales

and silt fences) are frequently limited in their effectiveness.

Erosion will be controlled by the following steps.

Clean 'run-on' water will be diverted from upslope around the disturbed area. Care

will be taken to ensure that such diversion of storm water above the disturbed area

does not itself cause flooding, erosion or scour.

Vehicle will be restricted to access to one stable entry and exit point.

Preserving grassed areas and retains the maximum cover of natural vegetation by

minimizing the amount of land disturbed by shaping. Mulch or revegetate disturbed

areas as soon as possible.

It will be ensured that stockpiles of sand, gravel, soil and similar materials are

located so that material:

- does not spill on to the road or pavement

- is not placed in drainage lines, depressions or watercourses

- cannot be washed into roadways, drainage lines, depressions or watercourses.

Accidental spills of soil or other materials on the roadway or gutter will be removed

daily.

Excess materials and water from cleaning tools and equipment down storm water

drains will be avoided.

Minimize on-site vehicle activity during wet weather or when the site is muddy.

Sediment control measures

Sediment control structures aim to capture sediment or other pollutants washed from the land

surface, thereby stopping them getting into receiving waters. As previously mentioned, it is

far better to prevent erosion in the first place than to rely on sediment control.

However, construction activities inevitably involve some land disturbance. Sediment control

measures are therefore an essential part of construction site management.

Sediment can be controlled by sediment basins, sediment traps or sediment filters.

Sediment basins and/or the smaller sediment traps are excavations with a barrier or bank that

may be constructed from a broad range of materials, including earth, gabions and rock, lined

with geotextile material . Sediment basins and traps are generally used to treat channelised

flow, generally by a combination of settling and filtration.

It is imperative that sediment controls, whether basin, traps or filters ,be regularly ,inspected

and maintained to ensure effective operation.

During the construction phase, runoff from the construction site shall not be allowed to stand

or enter into the roadside or nearby drain. Adequate measures shall be taken to collect such

run off and either shall be reused (if possible) or disposed at the designed construction waste

disposal location. Suitable garlanding drain as per the existing contours of the plot will be

developed.

2.11. 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):

As detailed out in Clause 2.7.

2.12. Will the deployment of construction labourers particularly in the peak period lead to

Unsanitary conditions around the project site (Justify with proper collection explanation):

Proper sanitary facilities like common bath place, temporary toilets etc. will be provided to

laborers and treatment will be done using septic tank.

2.13. What on-site facilities are provided for the, treatment & safe disposal of sewage? (Give

details of the quantities of wastewater generation, treatment capacities with technology &

facilities for recycling and disposal)

Domestic Wastewater Disposal:

The liquid effluent of 1113.12 KLD will be treated in 1200 KLD STP .

2.14. Give details of dual plumbing system if treated waste used is used for flushing of toilets

or any other use.

All the buildings shall have domestic and flushing water OH tanks separate, and separate

down take stacks, the flushing water line shall supply to the WC flushing cisterns only,

where as the domestic water shall be supplied through a separate down take system to all

other outlet points.

3. VEGETATION

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

ecosystem with it‟s unique features, if any):

There are no major wild life sanctuaries/parks within 10 km radius of the project site. Neither

any rare or endangered species have been recorded in the project influence area. There is no

notified natural/ Reserve forest area in the North West District. The Delhi NCR region falls

under a transition zone between the North Western Thorn Scrub Forest(IM1303) ecoregion

and Upper Gangetic Plains moist deciduous forests (IM0166) ecoregion, as delineated by

World Wildlife Fund for Nature (WWF). This transition zone bears characteristics of both

the ecoregions, and varies gradually from east to west. The study area represents the thorn

scrub forests in north western region of the Indian subcontinent. Many ecologists consider

this thorn scrub to represent a degraded state of tropical dry forests (Champion and

Seth,1968; Puri et al. 1989).

Babool (Acacia spp.), Eucalyptus (Eucalyptus hybrid), Shahtoot (Morus alba), Neem

(Azadirachtaindica), Seemal (BombaxCeibs),Aswath (Ficusbengaensis), Bel

(Aeglemarmelos) Amaltash (Cassia fistua), Sahjan (Moringaoleifera), Peepal (FicusreCAT-

IIiosa), Gulmohar (Delonixregia) are among the common dominant tree species found in the

study area.

Other than the large trees, some shrubs could also be located in the study area,dominated by

Thevetianerifolia, Langerostomiaspeciosa, Lantana camara etc. Lower no flowering plant

forms and cryptogamous vegetation are absent during the time of study. Climbers and lionels

were fewer in number.

The ecology of the study area is not very rich in diversity or high in endemism which may be

primarily accounted for the scattered distribution of poor quality and quantity of fodder. The

major mammalian fauna of the project influenced area involve common languor, Rhesus

macaques (macaquamulata) mongoose (Herpestrisedwardii) etc. Avifauna is primarily

represented by Common crow (Corvusspendens), House sparrow (Passer domesticus), bue

rock pigion(Columba livia), Rose ring paraqeet (Piteculacramerii),spotted doves

(Streptopeliachinensis) and finches. Common peacock (Pavocristatus), are known to be

present in the area. Small reptiles; primariysquamateslikeizards,chameleons, poisionous&

non-poisionous snakes are also found in the study area.

Amphibians and fishes are primarily restricted to the water logged and marshy areas. This

might account for their significant absence in the project influenced area. However the study

area represents densely distributed human habitation. Lack of suitable habitat and proper

food & fodder has lead away most of the faunal variety away from human habitations.

No endangered or endemic species (as notified in IUCN Red Data Book) are located within

the study area. No migratory birds breed in the study area. No Tiger reserve/ elephant reserve

/ turtle breeding place is located within 15 km radius of the study area.

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 proposed site is an open land which has been earmarked under Residential Landuse in

Master Plan of Delhi.

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):

There will not be any kind of impact of this project on site features. The Green Belt for the

proposed project has been planned in an area of 9060 SQM to provide a clean, healthy and

beautiful green environment for the people to live in and work in. Within the proposed

project site green bet area has been designed to achieve a blend between modern building and

various species of plants shrubs to create a clean, healthy and aesthetic environment that

provides a visual retreat and relaxation to the occupants of these buildings. A combination of

evergreen trees and deciduous species is used I these complexes. Some of the species are as

follows: -

species) should be undertaken at the time of preparation of the site so that they would grow

to considerable size by the time of commissioning of the proposed project.

Kindly refer for landscaping plan of proposed CAT II & EWS Housing Complex.

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.

The proposed site is an open land and devoid of forestation, so in existing conditions, this

pace is not the habitat for local fauna. There will not be any type of displacement or any

other effect on the local fauna due to proposed project activities.

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

Within the proposed project site, proper landscaping has been panned to provide a clean,

healthy and beautiful green environment for the people to live in and work in. Common

native variety of trees and ornamental flowering species will be planted in the green space.

Landscaping can have direct positive impact on the local avifauna, as this will provide shelter

to local birds.

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

fauna:

These measures are applicable for this project.

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

constructions):

Increased traffic generation 1268 no. of vehicles due to project is not going to cause

significant increase in atmospheric concentration of gases and will not result in heat island

formation.

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.

Air Pollution Dispersion Relationship with Meteorology

The measurements of wind speed and direction, temperature, humidity, rainfall and solar

radiation are important parameters used in the study of air quality monitoring results and to

further understand the chemical reactions that occur in the atmosphere. Meteorological

monitoring is used to protect air pollution events such as inversions, high pollutant

concentration days and to simulate and predict air quality using computer models.

Wind Speed and Direction

The region has a semi-arid climate with extreme seasons, hot summers, and heavy rainfall in

the monsoon months and very cold winters. The mean monthly temperature ranges from

14.3OC in January (minimum 3

OC) to 34.5

OC in June (Maximum 47

OC). The annual mean

temperature is 25.3OC (WMO 1971)

Dust storms occur frequently during the summer months, leading to a build-up of particulate

matter in the atmosphere.

The monsoon period is favorable from the pollution point of view due to the frequent

washout of pollutants along with rain. Mixing height is an important parameter that

influences the dilution of pollutants. It varies diurnally as well as seasonally.

During the construction and operation phase of proposed project, air pollution causing agents

can be vehicular movement and occasional use of DG sets.

Stacks for DG Sets will be provided with proper height as per CPCB Guidelines and

emissions from DG sets will meet the stipulated norms as per NAAQM.

project provision, wide service road is made for the smooth traffic movement. Internal roads

with suitable width have also been provided. Adequate CAT-II arrangement has been

provided covering al corners.

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.

The prime sources of noise levels during the construction phase are the construction

machinery and the vehicular noise. The effect of noise would be significant during day time,

the residential area located in the near vicinity of the construction site may increase in the

day time as well as night time ambient noise levels.

Mitigation Measures

The main stationary noise producing sources such as generators should be provided with

noise shield around them.

For protection of construction workers, earplugs should be provided to those working very

close to the noise generating machinery.

(a) Suitable damping the air compressor noise

(b) Silencers/mufflers in the air compressor and DG sets should be provided

(c) Regular preventive maintenance of pumps and other rotating equipments

will reduce the noise levels.

During the operation stage, there would be a minor increase in ambient noise levels in and

around the site due to Housing activities there will be quiet large no of population.

Mitigating Measures

Development of Greenbelt around the CAT II& EWS Residential complex can bring a

considerable reduction in noise levels;

During night & day time use of horns should be restricted

The noise generation levels will be confined within the surrounding area of construction site

and unlikely to affect the area 100 m away form the site. Construction period is only for

about two years, hence there will be short term, localized and reversible impact on ambient

noise levels during the construction activity.

Acoustic barriers should be placed near construction sites.

The maximum noise levels near the construction site should be limited to 75dB (A) Leq (5

min.) in industrial areas and to 65 dB (A) Leq (5 min.) in other areas.

There should be fencing around the construction site to prevent people coming near the

site.

Materials need not be stockpiled and unused equipment to be placed between noisy

operating equipments and other areas.

Constructing temporary earth bund around the site using soil etc, this normally is hauled

away from the construction site.

It is envisaged that there shall be maximum movement of CAT-IIht motor vehicles and 2-

wheelers inside the Residential Complex, hence this will have insignificant rise in noise

level. Moreover, this will be further minimized by plantation on the sides of internal roads,

on the open spaces inside and around the periphery of whole Residential Complex. Proper

maintenance of the internal roads will be carried out and informatory signboards shall be

provided to encourage vehicle owners to maintain their vehicle, not to bow horns and follow

the emission standards fixed by Government Authorities.

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.

Stacks for DG sets will be provided with proper height as per CPCB Guidelines and

emissions from DG sets will meet the stipulated norms as per NAAQM. Noise emission from

DG sets will meet the noise levels as per CPCB Guidelines.

windows are recessed or with projection to solar passive.

9.4. What passive solar architectural features are being used in the building? Illustrate the

applications made in the proposed project.

Building design and envelope has been optimized through section of appropriate wall and

roof construction and through adoption of solar passive measures after studying the sun path

analysis to provide shading devices for windows and roof, which would reduce energy

demand. Sunshades will be used around windows in order to protect from direct sunCAT-

IIht. Use of recessed windows, which can be recessed 600 to 700 mm from the external wall,

will reduce the load due to solar radiation by 30% and it will effectively reduce the heat load

of the building envelope.

9.5. Does the layout of streets & buildings maximize the potential for solar energy devices?

Have you considered the use of street Lighting, emergency -Lighting and solar hot water

systems for use in the building complex? Substantiate with details.

as against total connected load of approx 16840 KW.

Solar panels may be installed for street lighting , subject to policy decisions of DDA .

9.6. Is shading effectively used to reduce cooling/heating loads? What principles have been

used to maximize the shading of Walls on the East and the West and the Roof? How much

energy saving has been effected?

The East – west walls are mostly blank wall with minimum window fenestration. Otherwise ,

2 mt wide balcony projection along the longer sides of the building blocks creates a solar

passive envelope.

Passive solar architectural measures have been adopted to provide shading devices for

windows and roof, which would effectively reduce heating up of building envelope. Sun

shades will be used around widows in order to protect from direct sun light

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

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

heat island & inversion effects?

The proposed project is the construction of Residential Complex due to which there will not

be any significant effects on the surrounding environment of proposed project, hence no heat

island effect is envisaged. The proposed project is a Housing Complex, which is intended to

use only for residential purpose and will be constructed within the designated site as per the

defined building by laws of Delhi Development Authority. Increased traffic generation and

occasional use of DG sets use due to project is not going to cause significant increase in

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

The ratio between the hard surface and green surface (grass, shrubs and trees) on the

Plot shall be less than 0.4. The front Plaza is also interspersed with green areas and

flower beds. Therefore, there is neither creation of Heat Islands nor any inversion

effects

(B) ENVIRONMENTAL MONITORING PLAN

The environmental monitoring programme is a vital process in the Management Plan for any

construction project. This helps in signaling the potential problems that would result from the

proposed project and will allow for prompt implementation of effective corrective measures.

The environmental monitoring will be required during construction & operational phases.

Water Quality and Public Health

Since water contamination leads to various water related disease, the project authorities shall

establish a procedure for water quality surveillance and ensure safe water for the consumers.

Detailed epidemiological study related water born disease shall be carried out and the data

shall be compiled for every year in the project area. This data would help the authority in

finding out the trends for incidence of water related diseases prevalent in the area, which

would help them to take suitable remedial measures for reducing or eradicating the

occurrence of these diseases in future.

Water quality parameters shall be monitored before and after the completion of the project.

Monitoring shall be carried out on quarterly basis to cover seasonal variations. Water quality

shall be analyzed by applying the standard techniques. The parameters recommended for

monitoring are as follows:
