3.1 INTRODUCTION OF THE BACKGROUND INFORMATION
3.1.1 Brief Description of the Nature of the Project: The proposed project is Expansion of “Hotel Seven Seas” at Plot No. 12, Mangalam
Place, Sector-3, Rohini, Delhi being developed by M/s Seven Seas Hospitality Private
Limited. The project had already been granted Environmental Clearance for the
development of “Hotel Seven Seas” (5-star hotel) vide letter no. F.No. 99/DPCC/SEIA-
SEAC/10/1786-1790 dated 16.03.2011 for plot area of 7127 m2 (0.7127 ha.) and built
up area of 32021.39 m2. The existing built-up area is 32019.71 m2 and the complex is
operational.
Now, due to change in planning, there has been increase in FAR area from 15899.64 m2 to 18273.17 m2 Therefore, the built-up area has been increased from 32019.71 m2
to 34392.941 m2. Therefore, we have applied for Environmental Clearance for the expansion of the
project. As the built-up area of the project is less than 1,50,000 sqm, hence it falls
under category B, item 8(a) of schedule of EIA notification, 2006.

proposed project and take appropriate actions to properly manage that risk. Adequate
Expansion Of “Hotel Seven Seas” by M/s Seven Seas Hospitality Pvt. Ltd.
64
Environment Consultant: -M/s Perfact Enviro Solutions Pvt. Ltd.
environmental management measures need to be incorporated during the entire
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.
3.6.1 ENVIRONMENT MANAGEMENT DURING CONSTRUCTION
3.6.1.1.1 AIR ENVIRONMENT : -
Air quality around the project will be 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 will be taken:
❖ Wind breaking walls shall be provided around the area under construction.
❖ All the loose material either stacked or transported will be provided with suitable
covering such as tarpaulin, etc. and kept in and specific place.
❖ The constructed buildings will be kept covered with a green cloth.
❖ Water sprinkling will be done at the location where dust generation is anticipated.
❖ Wet jet stone cutting will be followed to avoid dust emissions.
Expansion Of “Hotel Seven Seas” by M/s Seven Seas Hospitality Pvt. Ltd.
65
Environment Consultant: -M/s Perfact Enviro Solutions Pvt. Ltd.
❖ To minimize the occupational health hazard, proper mask will be provided to the
workers who are engaged in dust generation activity.
❖ DG sets of capacity 62.5 KVA shall be installed acoustically enclosed with adequate
stack height above roof level of DG sets.
Tankers supplying STP treated water will be used for supply of construction water.
Sprinkling will be done at the source of dust anticipated.
The proposed project will involve construction activities; which will obviously result in
fugitive dusts. These fugitive dusts shall be controlled by carrying out construction
after covering the boundary of the proposed project site by polythene cover to a
particular height and also by intermittent spraying of water.
3.6.1.1.2 WATER MANAGEMENT: -
During the construction of the proposed project, the services required like water
supply and sewage facilities shall be arranged on a temporary basis and the same shall
be maintained without any adverse impact on the environment. Following are the
measures required to manage the water environment at site:
• 10 KLD of water is required for domestic use & construction purpose. Water shall
be taken from STP treated water of nearby area/ STP supplied through Tankers.
• 4 KLD of the sewage and waste water generated shall be discharged into septic
tank which will be cleaned regularly.
• Runoff from the construction site shall not be allowed to stand (water logging) or
enter into the roadside or nearby drain. Adequate measures shall be taken to
collect such run off and either are reused or disposed off at the designated
construction waste disposal location.
3.6.1.1.3 NOISE ENVIRONMENT: -
During the construction stage, expected noise levels will be in the range of 80-100
dB(A), which will decrease with increase in distance. Hence all the construction
activities shall be carried out during the daytime.
Due to the construction activities undertaken for the project, there will be some noise
generation due to the movement of vehicles carrying construction materials and as
this will be only a temporary phenomenon, it shall be managed by properly regulating
the movement of vehicular traffic so that the ambient noise quality will not be
adversely affected.
Expansion Of “Hotel Seven Seas” by M/s Seven Seas Hospitality Pvt. Ltd.
66
Environment Consultant: -M/s Perfact Enviro Solutions Pvt. Ltd.
To prevent any occupational hazard, ear muff / ear plug shall be given to the workers
working around or operating the plant and machinery emitting high noise levels.
Operation of such plant or machinery shall be strictly prohibited during night hours.
Careful planning of machinery operation and scheduling of operations shall be taken
to minimize such impact. Furthermore, following measures shall also be adopted:
• All the machinery and equipment shall be regularly maintained to reduce the noise
level.
• DG sets of capacity 62.5 KVA shall be installed acoustically enclosed.
• Noise barriers shall be installed to reduce traffic noise & vibrations.
• Plantation shall be developed along the periphery of the site.
3.6.1.1.4 SOLID WASTE MANAGEMENT: -
During the construction, no excavation work is required as the 3 number of basements are already there.
Construction debris like Concrete will be recycled and will be used in lean concrete,
brick work wastage will be used waterproofing for terrace, toilets etc. Tiles will be used
in creating pathways in the landscape area etc. Recyclable material like aluminium,
steel, wood pieces, cement bags, plastic containers, cartons, glass etc. will be sold to
recyclers.
Approx. 9 kg/day of Municipal solid waste shall be generated from temporary labours
which shall be disposed off at Municipal Landfill site.
Used oil whenever generated from the DG sets shall be kept in a secured place and in
leak prof container and shall be sent to approved recycler.
3.6.2 ENVIRONMENT MANAGEMENT DURING OPERATION 3.7.3.1 AIR ENVIRONMENT
DG set of 3x1010 KVA have already been installed as power backup for emergency use
during power failure. Proper stack height of 6 m above roof level has been maintained
which will help in reducing the air pollution. Table 3-8: DG set & stack Height
As per the specifications from D.G. Set manufacturer following emissions shall be
maintained, as given in table below.

3.7.3.2 WATER MANAGEMENT
In the existing complex, total water requirement is 327 KLD. After expansion, total water requirement has been estimated to be 332 KLD for the proposed project and will be met by Delhi Jal Board. Water shall be used mainly for domestic, flushing, DG & HVAC Cooling, Kitchen and gardening purposes. Total quantity of wastewater generation will be 141 KLD for the proposed project. The generated sewage will be treated in STP of capacity of 260 KLD (Existing 160 KLD STP shall be augmented to 260 KLD). The treated water of 134 KLD shall be generated from STP which will be completely reused for flushing, DG & HVAC Cooling & gardening purposes.
3.7.3.2.1 WASTEWATER TREATMENT
The Sewage Treatment Plant of capacity 160 KLD which will be augmented to 260 KLD
offered has some distinct advantages over conventional activated sludge processes.
The scheme is proven, under a variety of operating conditions, and is highly flexible in
operation.
The generation of waste water will be about 141 KLD from the complex which will be treated in the sewage treatment plant of STP of capacity 260 KLD (Existing 160 KLD STP shall be augmented to 260 KLD) based on Fluidized Aerobic Bioreactors (FAB)-260 m3/day technology).
Expansion Of “Hotel Seven Seas” by M/s Seven Seas Hospitality Pvt. Ltd.

Environment Consultant: -M/s Perfact Enviro Solutions Pvt. Ltd.
SCHEME OF SEWAGE TREATMENT PLANT DESIGN CRITERIA
The sewage treatment plant (BASED ON FLUIDIZED AEROBIC BIOREACTORS(FAB)-260 m3/day) shall be installed to treat the raw sewage having the following characteristics: Flow : 141 KLD pH : 7.5-8.0 BOD : 200-300 mg/l COD : 400-500 mg/l TSS : 100 mg/l Treated sewage characteristics will be as follows: pH : 6.5-9.0 BOD : 10 mg/l COD : 50 mg /1 TSS : 20 mg/1
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 requirement
Figure 6: Schematic diagram of STP and process flow
Expansion Of “Hotel Seven Seas” by M/s Seven Seas Hospitality Pvt. Ltd.
69
Environment Consultant: -M/s Perfact Enviro Solutions Pvt. Ltd.
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 fewer 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.
Nutrient removal
The bio-reactor system operates at very food to micro-organisms ratio (F / M ratio). This helps in totally converting the Ammoniacal 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 aluminium ions dosed in form of Poly Aluminium Chloride (PAC). Phosphates react with aluminium ions and precipitate as aluminium 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.

Environment Consultant: -M/s Perfact Enviro Solutions Pvt. Ltd.
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.
3.7.3.2.2 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. In the existing complex there are 2 no. of RWH pits and no further pits will be constructed. 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.

3.7.3.3 NOISE ENVIRONMENT
The main sources of the noise pollution are D.G sets. of 3 X 1010 KVA already installed
in the project.
DG sets are bought acoustically enclosed and meets the norms prescribed by CPCB.
Planting of the trees at the boundary of the project helps in reducing the level of the
noise within the project.
Location of DG sets: Basement
Insulation of air inlet and outlet points
The sound travels along with air therefore it is necessary to control the travelling
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 Insulated service door
The maintenance and servicing of D.G. 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.

3.7.3.5.1.1 Hazardous Waste Management: - Hazardous waste is a waste with properties that make it dangerous or potentially
harmful to human health or the environment. The universe of hazardous wastes is
large and diverse. Hazardous wastes can be liquids, solids, contained gases, or sludge.
They can be the by-products of manufacturing processes or simply discarded
commercial products, like cleaning fluids or pesticides. All hazardous wastes are
required to be treated and disposed off in the prescribed manner.
The main objective is to promote safe management and use of hazardous substances
including hazardous chemicals and hazardous wastes, in order to avoid damage to
health and environment.
