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.

3.5 PROPOSED INFRASTRUCTURE

3.5.1 Types of Buildings & Activities Proposed The proposed project is an expansion of “Hotel Seven Seas” (5-star hotel) and the Activities existing at the site is given below. The activities after expansion will remain the same.

• Guest Rooms (no. of guest rooms-104)

• Banquet Hall (3 in number)

• All day dining hall (1 in number)

3.6 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


64


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.


65


❖ 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.


66


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).


68


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


69


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.


70


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.

Table 3-14: Hazardous & E-Waste Management

E-Waste Management

Battery waste will be generated from inverters & UPS, which shall be treated as per

the Batteries (Management & Handling) Rules, 2001.

3.7.3.5.1.2 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 1920.51 m2 with trees

and plants. The trees planted are of adequate height.

No. of trees requires= plot area/80 = 7127/80=89

3.7.3.5.1.3 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


76


conform to soil and hydrological conditions. Indigenous species are preferred for the

purpose.

3.8 ANTICIPITATED IMPACT & MITIGATION MEASURES

3.8.1 DURING CONSTRUCTION PHASE S.

No.

Description Impacts Mitigation Measures

1. Air & Noise

Environment

Dust will be generated due to

Site clearance and emissions

may be generated due to

vehicles, DG sets and

machinery/equipment etc.

Loading and unloading of

construction materials like,

cement, sand, stones, bricks,

etc. will result in dust

generation.

Procurement and transport of

construction materials such as

sand, cement etc. will also result

in dust generation

Water sprinkling shall be

done to reduce the dust

during construction of

buildings.

D.G. set of 62.5 KVA shall

be provided with

adequate stack height to

avoid emissions.

Trees will be planted

along the construction

site to reduce dust &

emissions.

2. Water

Environment

Soil runoff from the site leading

to offsite contamination

(Particularly during rainy

season).

Improper disposal of

construction debris leading to

off-site contamination of water

resources.

Disposal of domestic waste

water from temporary labour

rest rooms.

Spillage of oil and grease from

the vehicle and waste water

stream generated from on-site

activities.

During construction

phase, water will be

provided from the

nearby STP/tanker

water supplier.

The rain water from the

construction site shall be

collected, treated &

reused for sprinkling.

Approx. 4 KLD of sewage

from labours shall be

discharged into septic

tank which will be

cleaned regularly.


77


3. Solid Waste The waste from labour rest

rooms/sheds would be mainly

household domestic waste

The solid waste generated

during construction phase used

oil from DG sets.

Approx. 9 kg/day

municipal solid waste

shall be generated from

60 labours which shall

be disposed off in MSW

site.

Used oil whenever

generated from the DG

sets shall be kept in an

isolated area and in leak

proof container and sent

to approve recycler.

3.8.2 DURING OPERATION PHASE S. No. Description Impacts Mitigation Measures

1. Air & Noise

Environment

Running of DG sets of

capacities 3 x 1010 kVA during

power failure will result into

air emissions.

DG sets have been provided with

stack height of 6 m above roof

level as per CPCB norms.

2. Water

Environment

During the operation phase

abstraction of water is not

proposed for project. After

expansion fresh water

requirement of 198 KLD shall

be met by municipal supply of

Delhi Jal Board.

In the proposed project, water

will be used for domestic use,

flushing, DG & HVAC Cooling

and gardening purposes etc.

Therefore, wastewater

discharge will be liquid waste

and sewage and shall be

treated in STP of 260 KLD

(Existing 160 KLD STP shall be

augmented to 260 KLD) and

reused in flushing, DG & HVAC

Fresh water requirement shall

be reduced by using 134 KLD

treated water.

No treated will be sent to tanker

or discharged in sewer because

this will be a zero-discharge

complex.

Rain water is being recharged

into the ground water by 2 rain

water harvesting pits.
