3.7 ENVIRONMENT MANAGEMENT PLAN
The Environment Management Plan (EMP) is a site specific plan developed to ensure
that the project is implemented in an environmentally sustainable manner where all
stakeholders including the project proponents, contractors and subcontractors,
including consultants, understand the potential environmental risks arising from the
proposed project and take appropriate actions to properly manage that risk. Adequate
environmental management measures need to be incorporated during the entire
57
“Orris Market City” at Hayatpur & Badha, Sector-89 & 90, Gurgaon, Haryana
Being Developed by M/s Orris Infrastructure Pvt. Ltd.
planning, construction and operating stages of the project to minimize any adverse
environmental impact and assure sustainable development of the area.
The EMP presented below should be followed and regular monitoring of relevant
parameters as stated in post project-monitoring schedule shall be carried out. The EMP
is to be proactive in nature and will be upgraded if new facilities or modification of
existing facilities, with environmental concerns, come up at a later stage.
EMP includes four elements:

Commitment and Policy: Proposed project will strive to provide and implement
the Environmental Management Plan that incorporates all issues related to air,
land and water.

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 and Evaluation: This includes monitoring, corrective actions, and
record keeping.
3.7.1 ENVIRONMENT MANAGEMENT DURING
CONSTRUCTION
3.7.1.1 AIR ENVIRONMENT
Air quality around the project was adversely impacted during the construction stage.
Various construction activities especially related to lose material likely to cause
generation of dust that adversely impacts the air quality of the surrounding area of the
project site. To minimize such impact, following measures were taken:
 All the loose material either stacked or transported shall be provided with suitable
covering such as tarpaulin, etc. and kept in and specific place.
 Dust suppression systems (water spray) shall be done as per requirement at the
construction site.
 Wind breaking walls shall be provided around the construction site.
 Fly ash based cement / bricks shall be used in the construction only in side walls.
 Building under construction shall be covered with the green cloth and net screen
shall be provided on every floor throughout the construction.
 Water sprinkling shall be done at the location where dust generation shall be
anticipated.
 To minimize the occupational health hazard, proper masks shall be provided to the
workers who are engaged in dust generation activity.
58
“Orris Market City” at Hayatpur & Badha, Sector-89 & 90, Gurgaon, Haryana
Being Developed by M/s Orris Infrastructure Pvt. Ltd.
 Wet jet system shall be used for the stone cutting and grinding to avoid the emission
from the dry stone cutting.
 Wheel washing arrangement of construction vehicle shall be provided at site.
DG sets of capacity 62.5 KVA shall be installed acoustically enclosed with adequate
stack height above roof level of DG sets. The construction activity results in fugitive
dusts. These fugitive dusts was controlled by carrying out construction by covering the
boundary of the proposed project site and as well by polythene cover to a particular
height and also by intermittent spraying of water.
3.7.1.2 WATER MANAGEMENT
During the construction of the proposed project, the services required like water supply
and sewage facilities were arranged on a temporary basis and the same will be
maintained without any adverse impact on the environment. The water required for
curing and other construction purpose was arranged on temporary basis from treated
water from nearby STP.
During the construction period, runoff from the construction site was allowed to stand
(water logging) or enter into the roadside or nearby drain. Adequate measures were
taken to collect such run off and will be disposed off at the designated construction
waste disposal location.
3.7.1.3 NOISE ENVIRONMENT
During the construction stage, expected noise level was in the range of 70 dB (A), which
decreases with increase in distance. Hence all the construction activities were carried
out during the daytime.
As stated earlier, due to the construction activity undertaken for the project there would
be some noise generation due to the movement of vehicles carrying construction
materials and as this would only be a temporary phenomenon, it would be managed by
properly regulating the movement of vehicular traffic so that the ambient air quality
with respect to noise is adversely affected.
To prevent any occupational hazard, ear muff / ear plug were given to the workers
working around or operating the plant and machinery emitting high noise levels.
Operation of such plant or machinery were strictly be prohibited during night hours.
Careful planning of machinery operation and scheduling of operations shall be done to
minimize such impact.

3.7.1.4 SOLID WASTE MANAGEMENT
During the construction, the soil had been excavated approx.34406.08 Cubic meter.
This soil will be used upto extent possible for backfilling, levelling& other purposes
and the rest will be stacked and disposed off in authorized recycler for recycling the
waste which shall not cause any disturbance to the surrounding environment.
Trucks to the site transport the construction materials. At site, it will be handled
manually and by tractor trolley. As most of the materials are dry solids, there is air
pollution during their handling at different stages for which all mitigation methods will
be adopted.
3.7.2 ENVIRONMENT MANAGEMENT DURING
OPERATION
3.7.2.1 AIR ENVIRONMENT
DG sets of capacity 4 X 1250 KVA & 1 x 1010 KVA Capacity will be installed for
emergency use during power failure. Proper stack height of D.G Set will be maintained
which will help in reducing the air pollution. The DG sets will be installed with acoustic
enclosure.

Following description gives the salient features of the STP:
1. Small space requirement
The concept of compact sewage treatment plant is promoted so that expensive
conventional treatment is dispensed herewith. The treatment scheme is also versatile,
in the sense that units can be re-arranged in any way in which the space and pile caps
are available.
2. Lower operating power requirements
The system utilizes aeration tanks of much smaller size, thereby reducing the overall
power required in aerating the raw sewage. Since the bio-reactor depth is more, efficient
transfer of oxygen takes place, thereby reducing the overall power consumed in
treatment.
3. Simplicity in operation and maintenance
The system adopted has much less moving parts (only pumps and blowers). Further
there is no moving part inside the bio-reactor. This gives the advantage of continuously
running the bio-reactor system, under widely fluctuating conditions. All the
maintenance on the mechanical systems can be done with normal skilled mechanics
available.
The system is unique in operation, such that, only inlet and outlet parameters (i.e. raw
sewage BOD / COD / TSS /TP and treated sewage BOD / COD / TSS / TP etc.) need
to be analysed. Since the bio-reactor is self-sustaining, there is no requirement of
recycling the biomass from the secondary clarifier. Hence, analysis such as MLSS /
MLVSS / SVI (sludge volume index) / F / M ratio etc. is not required to be done. This
greatly reduces the analytical load on the plant chemist / supervisor, and makes the
system very simple to operate and control.
4. Removal of Nutrients & coliform
The bio-reactor system adopted in the FAB based STP is provided with nutrients
removal, and removal of disease causing E-coli bacteria.
63
“Orris Market City” at Hayatpur & Badha, Sector-89 & 90, Gurgaon, Haryana
Being Developed by M/s Orris Infrastructure Pvt. Ltd.
Nutrient removal
The bio-reactor system operates at very food to micro-organisms ratio (F / M ratio).
This helps in totally converting the Ammonicals nitrogen to nitrate nitrogen. In the
process of synthesis of organic substrate, about 40 – 50% of the total phosphates load
is also reduced. The remaining phosphates can be precipitated by addition of aluminum
ions dosed in form of Poly Aluminum Chloride (PAC). Phosphates react with aluminum
ions and precipitate as aluminum phosphate, which is an insoluble salt. Thus the total
phosphates load can be easily reduced by more than 90%.
Coliform removal
The outlet BOD of the bio-reactor system being very low (in other words, hardly any
food is available to the E-coli), most of the coliform are killed in the reactor itself. The
treated sewage outlet coliform count will conform to WHO standards.
5. Sludge handling
The sludge generated in the bio-reactors is totally digested. Since the F / M ratio in the
bio-reactors is very low, the excess sludge generation is lower than compared to the
conventional ASP system. Normally, this sludge is anaerobically digested to stabilize
the organic matter. The present system does not envisage any sludge digestion (since
the sludge is aerobically stabilized in the bioreactors itself), making the system more
suitable for operation with less manpower.
The excess sludge is separated in the secondary clarifier, and then disposed off either
on drying beds, or can be directly used as soil conditioner.

“Orris Market City” at Hayatpur & Badha, Sector-89 & 90, Gurgaon, Haryana
Being Developed by M/s Orris Infrastructure Pvt. Ltd.
3.7.2.2.3 TREATMENT PROCESS
The sewage is first passed through a Bar Screen Chamber & an Oil & Grease
Chamber where any extraneous / floating matter gets trapped.
The sewage is then collected in a Receiving Sump where the variations in flow and
characteristics are dampened, which otherwise can lead to operational problems and
moreover it allows a constant flow rate downstream. Here the sewage is kept in mixed
condition by means of coarse air bubble diffusion.
The equalized sewage is then pumped to the Fluidized Aerobic Bed Reactors(FAB)
where BOD/COD reduction is achieved by virtue of aerobic microbial activities. The
FAB reactors run in series. The oxygen required is supplied through coarse air bubble
diffusers.
The excess bio-solids formed in the biological process, which are separated in the
downstream Plate Settler Tank. The clear supernatant is sent to the tertiary treatment
section comprising of a Dual Media Filter and an Activated Carbon Filter, and UV
disinfections system. If needed Softener shall be provided.
The biological sludge generated from the FAB, which is settled in the Plate Settler, is
drained through the Filter Press.
3.7.2.2.4 Rain Water Harvesting
The main source of ground water recharging in the study area is rainwater, which
infiltrates into the ground through various lithological units present in the study area. 4
nos. of RWH pits are proposed in the shopping complex to recharge the ground water.
The runoff from the rooftop and storm water shall go to the recharge pits.

Scheme for Ground Water Recharging
The rainwater is diverted from the rooftop using rain water pipes to the surface /
underground drainage network. The entire campus is sub divided for recharging
structures. The rainwater is diverted into the desilting tank to remove inorganic
impurities and the outflow of the desilting tank is taken into the recharge well.

Desilting Tank
The desilting tanks are used to remove silt and other floating impurities from rainwater.
Desilting tank is like an ordinary container having provision for the inflow, outflow and
overflow. Apart from removing silt it holds the excess amount of water till it is soaked
up by the recharge structure. The bottom of tank will have unpaved surface (layers of
coarse sand) to allow standing water to percolate into the soil. The rainwater collected
in these desilting chambers shall be utilized for horticulture.

Recharge well
The recharge well consists of percolation pits with boreholes in the middle of the pit.
UPVC pipe perforated will be lowered in the middle of the boreholes and the pit will
be filled with gravel and pebbles in three layers consisting of boulders, gravel and

coarse sand. The mouth of the UPVC pipe shall be protected to avoid silt getting into
it. The depth of the bore will depend on the soil condition/water strata. The schematic
diagram is enclosed.
It should be therefore concluded that there is no significant impact on surface water
quality & hydrology of the area. The proposed rainwater-harvesting scheme will
stabilize the groundwater table in the area.

3.7.2.3 NOISE ENVIRONMENT:The main sources of the noise pollution will be D.G sets. DG sets of 4 X 1250 KVA
capacity & 1 x 1010 KVA will be installed in the shopping complex which shall be
bought acoustically enclosed and shall meet the norms prescribed by CPCB. Planting
of the trees at the boundary of the Complex will help in reducing the level of the noise
within the Complex.
3.7.2.3.1 Noise Pollution Control System
DG sets of 4 X 1250 KVA capacity & 1 x 1010 KVA Capacity will be installed for
power backup during power failure.

3.7.2.3.2 ACOUSTIC ENCLOSURE / TREATMENT
There are two methods to reduce noise from DG Sets.
1. Acoustic Enclosures [when DG Set is kept outdoor]
2. Acoustic Treatment [when DG Set is kept indoor]
ACOUSTIC TREATMENT:
(a) MAIN FRAME:
3’ 1.5” rectangular pipe will be used to make main frame of the panel covered with 18
gauge MS sheet from one side.
Insulation by Glass Wool:
3” thick glass wool pad of high density covered with tissue paper will be used for
absorption of sound.
Covering Layer:
Finally, the insulated material is covered with perforated galvanized (GI) sheet
(24SWG) to prevent damage to insulating material.
(b) AIR VENTILATION SYSTEM
The acoustic lining defined in above results in accumulation of heat generated by DG
Set. Therefore the temperature of the treated room may increase which may adversely
affect the life of DG Set. To overcome the said problem, a proper ventilation system
should be designed.
As per calculation of heat generated by DG Sets a regular fresh air is continuously
sucked from the enclosure with the help of two 20” axial fans. There have been two 24”
axial fans for the supply of fresh air. The pressure difference inside and outside of the
room has been less than 8 mm WG, which does not affect the normal running condition
of DG Sets.
(c) INSULATION OF AIR INLET AND OUTLET POINTS
The sound travels along with air therefore it is necessary to control the traveling sound
with the help of insulated ducts [2” glass wool pads and perforated sheets] and louvers
at inlet and outlet air points. The ducts have S-type shape to prevent any direct escape
of noise.
(d) INSULATED SERVICE DOOR
The maintenance and servicing of DG Set is done using a suitable service door of 5’ x
7’ size. The door is made of MS sheet and frames fully insulated with 3” thick glass
wool pad followed by perforated aluminium sheets.
The schematic layout of acoustic enclosure is given below:

3.7.2.7 PLANTATION
Green belt planning will be done with ecological perspectives for the project taking into
consideration and availability of space and other aspects. This will help in increasing
the aesthetic effect of the environment.
Since tree trunks are devoid of foliage, scrub should form there to give coverage to the
trunks. The trees maintain the regional ecological balance and conform to soil and
hydrological conditions. Indigenous species would be preferred.
Green belt/greenery has been developed along most of the periphery of the project area
as well as along roads. Area under plantation/greenery is 3905.21 sq m (25% of plot
area) with trees and plants. The trees planted are of adequate height. Any trees that do
not survive are replaced. The plantation/greenery programme will be completed,
simultaneously along with the project.
3.7.2.7.1 PLANTATION PROGRAMME LAYOUT
Plantation in the project area helps to arrest the particulate matter in the area and hence
attenuate the pollution to a great extent and contribute positively to the environment.
The trees also help in maintenance of regional ecological balance and conform to soil
and hydrological conditions. Indigenous species are preferred for the purpose.
