1. LAND ENVIRONMENT (Attach panoramic view of the project site and the vicinity)

1.1 Will the existing landuse get significantly altered from the project that is not consistent with the surroundings? (Proposed landuse must confirm to the approved Master Plan / Development Plan of the area. Change of landuse if any and the statutory approval from the competent authority to be submitted). Attach Maps of (i) site location, (ii) surrounding features of the proposed site (within 500 meters) and (iii) the site (indicating levels & contours) to appropriate scales. If not available attach only conceptual plans.

Ans: The project is an ongoing development of IQ CITY, a residential development project at Durgapur, over a land parcel of 2,02,125.12 sq.m (49.946 acres) and having a total built up area of 4,95,760.51 sq.m. The said development is predominantly residential in nature comprising 46 residential towers and 46 villas / bungalows alongwith substantial percentage of commercial amenities in terms of shopping mall, commercial shops, profit hospital, hotel etc. Thus, It is a combination of residential and commercial development with necessary amenities within the complex.

The land parcel for the said development is owned by Asansol Durgapur Development Authority (ADDA). SPS Mani Infrastructure Pvt. Ltd., through a Memorandum of Understanding (MoU) with ADDA, got the development and sale right for the said project to its end users.SPS Mani Infrastructure Pvt. Ltd., in later days, changed its name to IQ City Infrastructure Pvt. Ltd. and presently merged with Mani Square Ltd., the present applicant holding the development and sale rights and also applicant seeking the Environmental Clearance for the project.

The project had already applied to SEIAA, West Bengal on 10.07.2009 seeking Environmental Clearance. After complying all the requirements of the concerned authority (SEIAA and SEAC, West Bengal), a set of Stipulated Conditions was issued by SEAC, West Bengal vide Memo No. 763-2N-39/2009(E) dated 25.11.2009 to M/s SPS Mani Infrastructure Pvt. Ltd., the then project proponent and sanctioned building plan was sought after incorporating the said stipulated conditions in order to obtain Environmental Clearance.

In the mean time, the project was reconceived to be developed in three phases considering the market demand. Accordingly, it was partially redesigned to accommodate the changing requirements and municipal sanction for Phase I was obtained from Durgapur Municipal Corporation (the concerned municipal approval authority). Application for obtaining Environmental Clearance alongwith the sanctioned building plan was submitted to SEAC on 25.09.2012. Required clarification on subsequent days by the SEAC/SEIAA was also complied accordingly.

However, due to the immense pressure from the stakeholders and buyers of the project, construction of Phase I had to be started without obtaining Final Environmental Clearance, although strict compliance of stipulated conditions accorded by SEIAA, West Bengal had been followed during the construction. Rest Phases of the project are yet to be constructed at site.

Surrounding Features around Project Site: The Land parcel for IQ CITY is located in Durgapur in the district of Paschim Burdwan, in West Bengal. IQ City Connector to National Highway (NH – 19 (Formerly NH-2) is around 3.5km from the site. Nearest Railway Station is Durgapur (9km). Nearest Airport is Andal Domestic Airport (15 km). Project site of IQ City Medical College is situated almost adjacent to project site. The project site is abutted by 24m wide IQ City Road which connects William Carry Road in the north-west and J.L. Nehru road in the south. The project site is located closed to the industrial township of Durgapur. Predominant landuse of the site is residential consisting of low to medium rise development, although trend of high rise development is presently noticed. Project site is almost flat terrain with virtually no vegetation. A drainage channel, named Rajhir Nullah, is flowing adjacent to the project site carrying the stormwater as well as wastewater from the catchment area surrounding the site.

Detailed Car Parking Calculation is provided in S. No. – 5.3 of Form –IA.Detailed Car Parking Calculation is enclosed in Annexure 5.3.

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 landuse, disturbance to the local ecology).

Ans: The probable impacts due to the construction of IQ City on the existing facilities will be both short-term and long-term in nature. Some of the impacts will be beneficial to the community. On the other hand, some of the impacts will be adverse in nature. The likely beneficial and adverse impacts on the existing facilities surrounding the project site have been described below:

A. IMPACT ON OPEN SPACES While developing the construction, adequate preventive measures are being adopted to control the fugitive emission, wastewater discharge and construction waste disposal procedures, so that the open spaces around the project site do not get affected. During the operational phase also adequate preventive measures are taken for controlling the above issues. While executing the project, minimum disturbance to the land within the project site are done. Thus, impact of the project on adjacent open spaces is minimized.

B. IMPACT ON COMMUNITY FACILITIES Presently the commercial amenities exist along the abutting road in a sporadic way. But, no organized market center is located at the adjacent area of the proposed construction. Also, no hospital or school is located at immediate surroundings of the project site. Therefore, no adverse impact will be posed on the surrounding facilities rather, due to the proposed development, surrounding existing community facilities have a lot of potential to develop.

C. EXISITING LANDUSE As the project site is located within an industrial area, the landuse of the proposed development is also designated with the surroundings. Therefore, no scope of modification of existing landuse is involved.

D. LOCAL ECOLOGY There is no tree within project site. Thus, there lies no scope of clearing or modification of trees and plantation due to the proposed project. Moreover, quite a number of trees will be planted within this complex. Therefore, local ecology will get improved.

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.

Ans: The soil of the study area has been developed under the dominant influence of river, vegetation and climatic factors. The area is under moderate anthropogenic pressure due to different human activities. The soil of the area consists mainly of sand, silt and clay, deposited by river, partly under river and partly under flat plains. The colour of the soil is grayish. Soil of the region is slightly alkaline in nature. The level of sand content is 75%, while silt content is 15% and clay content is 10%. Therefore as per U.S. Bureau of Soils and Chemistry Textural System (Triangular Classification System), the soil texture is loamy sand.

The site is leveled and situated above the flood level of the region, and the existing ground level of the project site is almost at the same level of the abutting road. Thus, no appreciable contour is noticed. Also, as the building blocks will have foundation, therefore excavation of earthwork and piling activities will take place. Therefore, while executing the project, the existing ground level will be modified. But, adequate measure will be taken to minimize the land disturbance of the project site and surrounding areas.

The surrounding area of the project site is predominantly residential. No mining or any other underground activity is carried on in and around the campus. Thus, regarding the subsidence, the project is not at all vulnerable. The area under study falls in Zone-III according to the Indian Standard Seismic Zoning Map. Suitable seismic coefficients in horizontal and vertical directions respectively, will be adopted while designing the structures. Consultant : CENTRE FOR SUSTAINABLE DEVELOPMENT, KOLKATA Page 5 of 26 Residential cum Commercial Infrastructure Project at Durgapur, West Bengal Form – IA Developer – Mani Square Ltd.

There are no chances of floods and landslide as the project site is located at a flat terrain and above the flood level of the region.

The soil profile of the surrounding area of project site is as follows: Stratum Below Description E.G.L. Stratum - I The uppermost subsoil, Stratum-I, fill, comprises loose grey/dark grey fly ash mixed with brick bats, fine mica flakes and fine sand content. Thickness varied from 1.30m to 5.3m. However, an average thickness of 3.8m was considered for this stratum.

Stratum - II The underlying stratum (Stratum-II) constituted of hard reddish brown lateritic soil mixed with traces of light blue, grey and yellow patches. Thickness varied from 1.19m to 2.5m.

Stratum – III Stratum-III was very stiff to hard yellowish brown, yellowish brown silty clay/sandy clay mixed with a few nodules, traces of light blue, grey and rusty brown patches and fine mica flakes. Thickness of the stratum varied from 4.0m to 11.69m.

Stratum – IV Stratum-IV consisted of very dense yellowish brown silty sand mixed with a few nodules, fine mica flakes, light blue, grey and rusty brown patches. Layer thicknesses obtained from boreholes showed the range between 2.90m to 7.45m. An average thickness of 6.0m was considered for this stratum.

Stratum - V Bottom most stratum (Stratum-V) comprised hard silty clay mixed with traces of light blue, grey, rusty brown patches, a few nodules and occasional deep brown patches. As all the boreholes were terminated within this stratum its thickness could not be decided. However, thickness obtained was more than 5.42m.

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)

Ans: No. The region is mainly drained by Rajhir Nullah that flows in south direction and quite closed to the project site. The nullah is perennial in nature. It meets the Ajay river, about 10 km east of project site. It is already mentioned that project site has very few appreciable slopes, although those are being modified due to the construction. A copy of survey plan showing contours lines is enclosed in Annexure 1.5.

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.)

Ans: The quantity of earthwork involved different construction activities are as follows: Excavation for foundation: around 80,000 cu.m earthwork will be required to be excavated. The filling material will be earth and sand.

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

Ans: During construction stage, required water are being catered by municipal supply from ADDA. Necessary permission in this respect is already obtained from the concerned authority. Construction waste will also be disposed to authorized agency of ADDA

1.8 Will the low lying areas & wetlands get altered? (Provide details of how low lying and wetlands are getting modified from the proposed activity)

Ans: During the field visit, the land of the project site is found to be little undulated. But, no low lying area or wetland

Consultant : CENTRE FOR SUSTAINABLE DEVELOPMENT, KOLKATA Page 6 of 26 Residential cum Commercial Infrastructure Project at Durgapur, West Bengal Form – IA Developer – Mani Square Ltd.

has been found in and around the project site. Therefore, there remains no chance for any wetland or low lying area to get modified from the proposed activity.

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)

Ans: Construction debris and wastes are the inevitable by-products of any construction activities, which may cause various kinds of health hazards for the on-site labourers and to the people residing in the surrounding areas. The proposed development is also not the exception. But, effective material management and environmental management measures will be adopted in order to minimize such construction waste. The domestic waste from the working as well as residing labourers will also be generated, to be disposed to authorized collection agency. It is difficult to quantify the volume of construction waste because of the following factors: • Phasing of construction activities • Skilled workmanship • Recycling of such waste. If the construction activities go in phases, the volume of waste can be minimized due to careful and optimum consumption of building materials. Skilled workmanship can reduce the volume of waste considerably through proper and careful material handling practice. However, around 2 to 5 % of material consumption may be considered as construction waste. Also, The domestic waste from the working as well as residing labourers will also be generated, the volume of which has been preliminarily assessed as 120 kg/day. This waste will also be disposed to the site designated by the municipal body.

A considerable number of building waste e.g. concrete, brickbats, plaster etc. can be used as land filling of the site & thus reducing the volume of disposable waste. The different components of such type of waste are: Major components: • Cement concrete • Bricks • Cement Plaster • Steel (for R.C.C, door/ window frames, roofing support staircase, railing etc.) • Rubbish • Stone (marble, granite, sandstone) Minor Components: • Conduits (Iron, Plastic) • Pipes (G.I, Iron, Plastic) • Electrical fixtures • Panels (wooden, laminated) • Others (glazed tiles, glass panes)

Disposal Plan Disposal measures of construction period waste are described below: • All construction wastes will be stored within the project site itself. Proper screen will be provided so that the waste does not get scattered. • Attempts will be made to keep the waste segregated into different heaps to the extent possible so that their further gradation and reuse is facilitated. • Waste that may be sold or land filled, will be kept separate within the site. • Suitable collection agencies will be hired for arranging to provide adequate numbers of skip containers/trolleys which may be parked at the site and removed with skip lifters or tractors depending upon the situation.

Considering water consumption for internal road cleaning as 150 lit/ 100 sq.m , the water required for the said purpose will be = (37,667.78 + 55,728.40 + 9,074.09) sq.m x 150/100 = 149205.4 litres/day say 149 kLD.

Total Water Requirement = (a) + (b) + (c) + (d) = (2,486 + 187 + 280 + 149)kLD = 3,102 kLD. (Fire Fighting water requirement is not considered since this is a static demand. Static Requirement of water for Fire-Fighting will follow the Fire Department Recommended Capacity.)

EXPECTED SOURCES Freshwater requirement is available from municipal supply. Required water for toilet flushing, air-conditioning, landscaping etc. will be catered by treated wastewater from the S.T.P.

WATER BALANCE DURING OPERATIONAL STAGE The water balance for the proposed complex has been done in following way: Water Requirement for domestic purposes = 2,486 kLD (source: freshwater & tr. wastewater) Water Requirement for Air-conditioning = 187 kLD (source: treated wastewater) Landscaping Water Requirement = 280 kLD (source: treated wastewater ) Internal Rd & Pvmnt Cleaning Water Requirement = 149 kLD (source: treated wastewater )

Consultant : CENTRE FOR SUSTAINABLE DEVELOPMENT, KOLKATA Page 9 of 26 Residential cum Commercial Infrastructure Project at Durgapur, West Bengal Form – IA Developer – Mani Square Ltd.

Total Water Requirement = 3102 kLD (this quantity excludes the fire-fighting requirement, as that is a static demand) Generated Wastewater from domestic activities = 2237.4 say 2237 kLD (90% of domestic water consumption i.e. 2486 kLD) Wastewater Available from S.T.P. = 2,125.15 say 2125 kLD (95% of inflow domestic wastewater 2350 kLD) Treated Wastewater to be reused for toilet flushing = 829 kLD Treated Wastewater to be reused for Air-conditioning = 187 kLD Treated Wastewater to be reused for Landscaping = 280 kLD Treated Wastewater to be used for Int. rd & pvmnt. cleaning = 149 kLD Total Volume of Treated Wastewater to be reused = 1445 kLD Thus, treated wastewater to be discharged into adjacent drainage channel = (2125 – 1445)kLD = 680 kLD.

Water Balance diagram is enclosed in Annexure – 2.1.

2.2 What is the capacity (dependable flow or yield) of the proposed source of water?

Ans: During the operation phase of the project, required water will be supplied by ADDA, the regulatory authority of Durgapur. They are supposed to treat the surface water from river and supply. During the construction phase, required water will be available by abstraction of groundwater with prior permission in an authorized way.

The project site and the buffer zone of 314 sq km area comprise a part of the Damodar Valley Region of Eastern India. Three major geomorphic units characterize the Region: (i) the Peninsular Shield of Precambrian age formed of metamorphic and igneous rocks, (ii) the Gondwana Basin underlain by a sequence of sedimentary rocks with layers of coal of Late Paleozoic age and (iii) the Bengal Basin filled with Tertiary sedimentary rocks in the base and topped by soft sediments of Quaternary age.

Groundwater in the area occurs under unconfined conditions within alluvium, residual soil, weathered mantle, and open fractures in the hard rock substrate. Joints and fractures planes play a vital role in the movement and storage of groundwater. Yield of tubewells are moderate to low. The river Damodar is under effluent condition within the area. Thus, groundwater gets depleted during the dry period.

2.3 What is the quality of water required, in case, the supply is not from a municipal source? (Provide physical, chemical, biological characteristics with class of water quality)

Ans: Not applicable. Required water is expected to be from municipal source during its construction as well as operational stage.

2.4 How much of the water requirement can be met from the recycling of treated wastewater? (Give the details of quantities, sources and usage)

Ans: In the proposed project, wastewater from the hotel, offices, retails and multiplex areas will be treated in Sewage Treatment Plants. Effluent and wastewater from the hospital block will be treated in a separate Sewage Treatment Plant. Treated wastewater from both the S.T.P.s will be collected together into a treated wastewater reservoir, from where it will be recycled substantially for different secondary activities like toilet flushing, air-conditioning, landscaping etc. Total volume of generated wastewater from domestic activities is 90% of domestic water consumption i.e. 2486 kLD X 90% = 2237 kLD, which will be treated in the S.T.P.s. The volume of treated wastewater will be 95% of inlet wastewater i.e.95% of 2237 kLD i.e. 2125 kLD, out of which 1445 kLD will be reused. Thus, it is seen 46.58% of total water demand can be met from recycling of treated wastewater.

2.5 Will there be diversion of water from the users? (Please assess the impacts of the project on other existing uses and quantities of consumption)

Ans: In the proposed project, there will not be diversion of water from the users.

2.6 What is the incremental pollution load from wastewater generated from the proposed activity? (Give details of the quantities and composition of wastewater generated from the proposed activity)

Ans: During the operational stage of the proposed project, the average daily domestic demand of water will be 2486 kLD. Therefore, generated wastewater will be in the tune of 2237 kLD. (90% of water consumption). Expected composition of raw and treated wastewater and effluent which will be primarily discharged into the treated wastewater reservoir within project site; are listed below:

Expected Wastewater Quality from Residential Units Parameter Raw Wastewater Quality Treated Wastewater Quality pH 6.5 – 7.5 6.5 – 7.5 BOD (in mg/l) 200 <20 COD (in mg/l) 350 <50 TSS (in mg/l) 150 – 250 <20 Oil & Grease (in mg/l) 15 – 20 <10

Expected Wastewater Quality from Offices, Retails, Multiplex & Hotel Parameter Raw Wastewater Quality Treated Wastewater Quality pH 6.5 – 7.5 6.5 – 7.5 BOD (in mg/l) 350 <10 COD (in mg/l) 700 <50 TSS (in mg/l) 250 <10 Oil & Grease (in mg/l) 45 - 60 <10

Expected Effluent Quality from Hospital & Speciality Ward Parameter Raw Effluent Quality Treated Effluent Quality pH 6.5 – 7.5 6.5 – 7.5 BOD (in mg/l) 450 <10 COD (in mg/l) 1200 <50 TSS (in mg/l) 300 <10 Oil & Grease (in mg/l) 20 - 25 <10 Thus, from the above table, it can be mentioned that the treated discharge is within the permissible limit will not impose additional incremental pollution load.

2.7 Give details of the water requirements met from water harvesting? Furnish details of the facilities created.

Ans: As per the SEAC Guidelines, West Bengal for rainwater harvesting, method of storing rainwater does not include the collection of rainwater from ground surface. The runoff from the ground surface will be channeled through the storm water drains and finally discharged into the Gour River passing through the site. Only the rooftop rainwater will be harvested. The expected availability has been assessed and mentioned below: According to the guidelines, RWH potential in 1000 sqm Roof Area is considered to be 7,68,000 litres and the storage facility to be created from 1000 sq.m Roof Area is 3 lacs litre (for 10 to 15 storied buildings & above),2.5 lacs litres (6 to 10 storied buildings) and 1.5 lacs (for 3-5 storied buildings) respectively. The calculations are shown in the tables below:

But all the harvested rainwater will be diverted to the recharge wells. There will be no collection tanks for collecting rainwater. Thus the entire volume will be recharged, which is 21910.59 kL/ annum.

RAINWATER RECHARGE WELL CAPACITY ASSESSMENT Rooftop rainwater will be directed to recharge wells within the site. Volume of rainwater to be recharged through recharge well is 21910.59 kL/ annum say 21911 kL/annum. Considering the monsoon period as 120

Consultant : CENTRE FOR SUSTAINABLE DEVELOPMENT, KOLKATA Page 12 of 26 Residential cum Commercial Infrastructure Project at Durgapur, West Bengal Form – IA Developer – Mani Square Ltd.

days, daily average recharge volume available is 21911/120 = 182.59 kLD say 183 kLD. Hence we can propose 60 recharge wells within the site each of which can provide recharge up to 3 kL per day.

2.8 What would be the impact of the landuse 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?

Ans: At present, the project site has some existing structures under construction. Therefore, the runoff characteristic is in the range of 0.4. After the execution of the project, where 21.554% of the plot area will be covered by building blocks and around 36.911% of the plot area will be metallic and paved. Rest area will be soft surface comprising tree plantation and landscaped ground surface. Thus, the runoff characteristics the building rooftops and ground surface will be different. Therefore, it can be said that the runoff characteristic of the project site will increase substantially after execution of the project. The quantified difference of runoff at the project site during the preconstruction and post-construction stage is obtained from the following Runoff-Rainfall Intensity Relationship equation: Q = 10 C i A Where Q = runoff in m3/hr, C = coefficient of run-off i = intensity of rainfall in mm/hr and A = area of drainage district in hectare During the pre-construction stage, following considerations are taken: C = 0.4 i = 40 mm/hr A = 2,02,125.12 sq.m (49.946 acres) = 20.21 Ha Therefore, during the preconstruction stage, runoff (Q) will be in the tune of: Q = 10 [0.4X 40 X 20.21] m3/hr = 3233.6 say 3234 m3/hr During the post-construction stage, following considerations are taken: C = 0.8 i = 40 mm/hr A = 2,02,125.12 sq.m (49.946 acres) = 20.21 Ha Therefore, during the post-construction stage, runoff (Q) will be in the tune of: Q = 10[0.80 X 40 X 20.21] m3/hr = 6467.2 say 6467 m3/hr Thus, the surface run-off of the project site will increase by 3233 m3/hr during the peak rainfall period. However this volume includes the rooftop runoff as well, which will be harvested. The remaining volume will flow through the storm water drain. To avoid water logging problem inside the project site, adequate measures will be adopted while designing the stormwater drainage network and drain sections to accommodate the peak runoff. However, the ground surface runoff will be discharged to the road side drain.

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)

Ans: There will not be long term impact on the groundwater due to the proposed project, as the required freshwater will be supplied by ADDA from surface water sources. However, during construction if municipal source is not available, groundwater might be abstracted with prior permission in an authorized way.

Groundwater in the area occurs under unconfined conditions within alluvium, residual soil, weathered mantle, and open fractures in the hard rock substrate. Joints and fractures planes play a vital role in the movement and storage of groundwater. Yield of tubewells are moderate to low. The river Damodar is under effluent condition within the area. Thus, groundwater gets depleted during the dry period.

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)

Ans: The precautions/measure to be taken to prevent the run-off from construction activities are mentioned in the Environmental Management Plan, enclosed. However, broadly it can be mentioned that the no construction wastewater will be discharged directly into the land, stormwater drain or into the river. A couple of Sediment trap of sizes 2.5m(L) X 2.5m(W) X 0.75m (D) and retention period of two hours will be constructed during the construction stage, where all construction wastewater will be discharged. After the sedimentation of the Consultant : CENTRE FOR SUSTAINABLE DEVELOPMENT, KOLKATA Page 13 of 26 Residential cum Commercial Infrastructure Project at Durgapur, West Bengal Form – IA Developer – Mani Square Ltd.

construction wastewater, the comparatively cleaner water will be partially reused and the rest part will be discharged into the municipal drain.

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)

Ans: During the post-construction stages, the storm water will be collected into the surface drainage network inside the campus. The drain sizes and sections will be designed in such a way that they can take the load of the peak rainfall period. All the surface drains will be covered by gratings to avoid the litter and other inert waste. Proper land gradient will be provided so that water logging inside the campus does not occur. The collected storm water from the building roofs during the rainfall period will be directed into an underground water reservoir inside the campus. The storm water of the ground surface will be discharged into the municipal drain. To reduce the surface runoff and subsequent increase in infiltration of rainwater, attempts will be made to maximize the green surface inside the campus. Adequate trees will also be planted. As the site is located in a comparatively undulating, appreciable slopes are available. The natural slope is generally from south-west to the north-east direction. Proper land grading will be provided so that the slope of the modified ground level remains towards the southern side of the project site, where the roadside drain is passing. Drainage and sewerage map is enclosed in the Annexure-2.11.

2.12 Will there be deployment of construction labourers particularly in the peak period lead to unsanitary conditions around the project site (Justify with proper explanation)

Ans: Proper on-site sanitation facilities will be provided for the construction labourers so as to avoid defecation in and around project site. Few numbers of toilets comprising latrine, bath, handwash facilities will be constructed inside the project site. Septic tank and soak pits will also be constructed for collection and treatment of domestic wastewater generated from the construction labourers use. Moreover, adequate water supply for drinking and other domestic uses will also be provided during the construction stage of the project. Therefore, it can be presumed that there will not be any deployment of construction labourer during the construction stage of the proposed project.

2.13 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)

Ans: The design of STP for IQ CITY, is based on the Waste Water generation rate and characteristics of Waste Water. The effluent is generated mainly from hospital. It is proposed to treat the effluent in Batch Reactor, in order to reduce the level of pollution in the Waste Water and make it suitable for use in Horticulture.

Sequential Batch Reactor is an attractive alternative to generate good quality water for recycle & reuse at a low operating cost.

Sequential Batch Reactor is an activated sludge system based on time than space. 1) In one unit, Sequential Batch Reactor can accomplish equalization and biological treatment with a timed, controlled sequence. Each of these processes occurs in separately constructed and equipped units of a conventional activated sludge system. 2) In Sequential Batch Reactor, multiple biological environments are created in sequence and maintained for optimal lengths of time based on each facility's specific needs. Each specific environment nurtures each specific type of biological life necessary for optimum performance at the right time and right stage of the process. For example, one type of bacteria absorbs excess phosphorous in the aerobic condition when aeration occurs; the bacteria are conditioned for this luxury uptake in the both anoxic and the anaerobic stages. 3) Thus Sequential Batch Reactor is simple but yet a controlled process with good degree of automation to perform the batch functions.

The four basic steps of a sequential batch reactor are: 1. Fill: Raw wastewater flows into the reactor and mixes with the biomass held in the Aeration tank.

2. React: The biomass consumes the substrate under controlled conditions. Consultant : CENTRE FOR SUSTAINABLE DEVELOPMENT, KOLKATA Page 14 of 26 Residential cum Commercial Infrastructure Project at Durgapur, West Bengal Form – IA Developer – Mani Square Ltd.

3. Settle: Mixing and aeration are stopped and the biomass is allowed to separate from the liquid, resulting in a clarified supernatant.

4. Decant: Supernatant or treated effluent is removed.

As discussed above, four major steps in the SBR completed in about four hours per batch: Fill : 0.5 Hrs React/Aerate : 2 Hrs Settle : 0.75 Hrs Decant : 0.75 hrs

PROCESS FLOW DIAGRAM

TREATMENT PROCESS The main components of the process adopted for the treatment includes the following:

¾ Screening of effluent from hospital wastewater through the separate bar screens.

¾ Collection of screened effluent from various sources by gravity and pumps into the Equalization Tank (EQT).

¾ Submersible pump to lift the sewage from EQT to the batch reactor tanks.

¾ Batch reactors are designed with time cycle to handle 5 batches per day. The time cycle is - Filling time, Reaction time, Settling time and Decanting time. Consultant : CENTRE FOR SUSTAINABLE DEVELOPMENT, KOLKATA Page 15 of 26 Residential cum Commercial Infrastructure Project at Durgapur, West Bengal Form – IA Developer – Mani Square Ltd.

¾ Screw pumps to transfer the sludge from the SBR tank to filter press for dewatering and disposal of sludge.

¾ After stabilization of sludge, treated water is decanted into the MGF through decanting pumps.

¾ Further removal of solids through multigrade filter (MGF) using sand and anthracite filtering media.

¾ Polishing and removal of color through activated carbon filter (ACF).

¾ After treatment /purification treated water finally collected in the treated water tank.

The Schematic Layout of S.T.P. and details are enclosed in Annexure-2.13.

2.14 Give details of dual plumbing system if treated waste used for flushing of toilets or any other use.

Ans: Treated wastewater will be used for toilet flushing. Thus, dual plumbing system are being adopted in this project.

3. VEGETATION

3.1 Is there any threat of the project to the bio-diversity? (Give a description of the local ecosystem with its unique features, if any)

Ans: No. The project will not pose any threat to the bio-diversity of the locality. Project site did not have any tree. However, 700 trees already have been planted within the site during Phase – I development. More number of trees will be planted as the other phases of the project get completed. Also, as the project site does not have any water body, therefore, no scope of disturbance to the aquatic flora is involved. Moreover, quite a number of trees are also going to be planted during the later period of the construction stage. The species will be predominantly native in nature so that they merge with the local ecosystem. The description of the local ecosystem is enclosed in Annexure – 3.1.

3.2 Will the construction involve extensive clearing or modification of vegetation? (Provide a detailed account of the trees & vegetation affected by the project)

Ans: No. The construction activity will not involve any clearing or modification of existing vegetation. Therefore, no tree will be affected by the proposed project.

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 or water bodies etc along with a layout plan to an appropriate scale)

Ans: Adequate measures will be taken to minimize the likely impacts of the proposed project on the surrounding as well as the project site itself and documented in the Environmental Management Plan. The landscaping and plantation programme and other details are shown in the landscape plan which is enclosed in Annexure-3.3. Around 2850 trees are being planted for the entire project site. This will include flowering and fruit bearing trees along the boundaries. Mostly native species will be planted. Decorative trees and hedges will be provided along pedestrian pathways. The indicative type and probable number of species to be planted are listed in Annexure-3.3.

4. FAUNA

4.1 Is there likely to be any displacement of fauna-both terrestrial and aquatic or creation of barriers for their movement? Prove the details.

Consultant : CENTRE FOR SUSTAINABLE DEVELOPMENT, KOLKATA Page 16 of 26 Residential cum Commercial Infrastructure Project at Durgapur, West Bengal Form – IA Developer – Mani Square Ltd.

Ans: It is already stated no tree exists within the project site. Moreover, the site is located within a planned industrial estate. Therefore, no scope of displacement of terrestrial fauna is expected. However adequate number of trees will be planted.

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

Ans: As there lies no tree at project site, hence, there likes no scope of displacement of avifauna from the project site is involved. However, more number of trees will be planted during the later part of the construction period of the project. During the operational stages, the planted trees will get matured and invite different birds from the surrounding. Therefore, a positive impact is expected.

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

Ans: There will not be any adverse impact on fauna due to proposed 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)

Ans: During the operational stage, the proposed complex will not generate any emission of dust, fumes or gas so that the atmospheric concentration of gases increase. However, as there will be a couple of building blocks, there might remain a possibility of slight increase in heat island effect, which can be mitigated in following means: i) Judicial layout of building block within the complex The building block within the complex is laid in such a manner that there remains sufficient amount of external open space between the blocks of adjacent premises so that the air movement does not get interrupted. ii) Reducing the footprint of building blocks Only around 21.55% of the land area will be occupied by building block. Thus, 78.45% of the land area will remain as open space. Therefore, much lesser heat gain will be over the green surface. iii) Selection of Building Materials The building materials will be selected in such a way that the solar heat gain over the vertical surface and roof is minimized. iv) Trees and Vegetation It is already stated that there is no tree within the project site. Moreover, sufficient number of shading trees will be planted inside the project site to reduce the air temperature within the project site and surroundings. v) Reduction in Hard Surface Hard surface in the form of metallic road will be kept minimum. The pavements will be of porous and light coloured material and open joints.

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.

Ans: Air Pollution Dispersion Relationship with Meteorology Any study of air pollution should include a study of the weather patterns (meteorology) of the local area because the fate of air pollutants is influenced by the movements and characteristics of the air mass into which they are emitted. If the air is calm and pollutants cannot disperse then the concentration of these pollutants will build up. Conversely, if a strong, turbulent wind is blowing any pollution generated will be rapidly dispersed into the atmosphere and will result in lower concentrations near the pollution source.

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 predict air pollution events such as inversions, high pollutant concentration days and to simulate and predict air quality using computer models.

Consultant : CENTRE FOR SUSTAINABLE DEVELOPMENT, KOLKATA Page 17 of 26 Residential cum Commercial Infrastructure Project at Durgapur, West Bengal Form – IA Developer – Mani Square Ltd.

Wind Speed and Direction Wind speed and direction measurements are important for air quality monitoring. If high pollutant concentrations are measured at a monitoring station the wind data recorded at the station can be used to determine the general direction and area of the emissions. When the likely source or sources have been identified they can then be managed to reduce the impacts on air quality.

The measurement of meteorological parameters is important to gain an understanding of the impacts of a region’s meteorology on air pollutant concentrations, the prediction of inversions, and for the study of wind field and dispersion modeling.

Assessment of the meteorology is important from the standpoint of understanding the nature and extent of air pollution in the study area. Climate has an important role in the build-up of pollution levels of any region.

In this connection, IMD data is given in Annexure 5.2.

5.3 Will the proposal create shortage of parking space for vehicles? Furnish details of the present level of transport infrastructure & measures proposed for improvement including traffic management at the entry & exit to the project site.

Ans: The project will provide ample car parking spaces for vehicles. At present, the project site is abutted by 24m wide road on its north side. Proper traffic segregation will be adopted within the premises. Pedestrian and vehicular traffic will be kept segregated. Therefore, conflicts in traffic movement inside the campus can be avoided. Parking space for around 2673 cars including the visitors’ car parking facilities will be provided during the operational phase of the project. Most of the car parking spaces have been provided within the building footprint. The entry and exit points of the campus will be separate. To avoid traffic conflict, loop road has been provided. All the internal roads will be have adequate width so that fire tender can move uninterruptedly. Car Parking calculation is provided in Annexure 5.3.

5.4 Provide details of the movement patterns with internal roads, bicycles tracks, pedestrian pathways, footpaths etc., with areas under each category.

Ans: Around 18.64% of the open area will be under road. There will not be any separate bicycle tracks or footpath. However, vehicular road and pedestrian pavement will be kept separated. The entry and exit of the complex will be at multiple locations of the plot facing the abutting road. A loop internal road is provided for smooth movement of vehicular traffic inside the campus. The layout of the internal road & pavements and traffic movement is enclosed in Annexure – 5.4.

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

Ans: No. As the complex will be purely commercial in nature, there lies scope of heavy traffic movement inside the project site. But, heavy traffic movement inside the site will occur in a particular time in a day, especially in the morning, when loading and unloading might take place. Except that, moderate traffic movement is expected. Also, the speed limit of the vehicles will be controlled. Moreover, traffic movement along the abutting Road is moderate and the abutting IQ City Road is around 24m wide due to which traffic congestion does not occur generally. Thus, there will not be any significant increase in traffic noise and vibration within the complex. Plantation with heavy foliage will be done along the periphery of the project site. Thus, the vegetation might act as noise buffer. Ambient noise levels in and around the project site have monitored and found to be closed to permissible limit.

5.6 What will be the impact of DG sets & other equipment noise levels & vibrations in & ambient air quality around the project site? Provide details.

Ans: Impacts on Air Quality due to DG Sets: Impacts: • Impacts on ambient air during operation phase would be due to emissions from the stacks attached to standby DG set only during grid power failure. Mitigation Measures Consultant : CENTRE FOR SUSTAINABLE DEVELOPMENT, KOLKATA Page 18 of 26 Residential cum Commercial Infrastructure Project at Durgapur, West Bengal Form – IA Developer – Mani Square Ltd.

• Back up DG sets will comply the applicable emission norms. • All the D.G. Sets will be silent type and proper acoustic enclosure will be provided in Generator Room. • Adequate stack height for DG sets will be provided as per norms. • Back up DG sets will be used only during power failure. • Periodic monitoring of emissions from DG sets and ambient air quality will be carried out as per norms.

6. AESTHETICS

6.1 Will the proposed constructions in any way result in the obstruction of a view, scenic amenity or landscapes? Are these considerations taken into account by the proponents?

Ans: No. Adequate open spaces according to the municipal building rules will be provided. Building orientation has been considered in such way that the natural scenic view and natural air movement do not get interrupted.

6.2 Will there be any adverse impacts from new constructions on the existing structures? What are the considerations taken into account by the proponents?

Ans: No. The construction are confined within the project site only. Sufficient external open spaces are provided on all sides of the project site. Moreover, precautionary measures are being adopted while excavating foundation or erecting superstructures by erecting vertical shoring to avoid landslide or soil erosion. It also helps to protect the structural stability of the surrounding existing structures. All the construction materials are stored within the project site itself. Around 1500 sqm area will be provided for stacking of construction materials. The stacking area will be fully covered to prevent spreading of dust. No construction materials or waste will be dumped outside the project boundary or along the abutting roads. Thus, there remains no chance of traffic closure or diversion, due to the proposed construction. Construction activities will be carried on during the day time only. Construction Wastes will be disposed properly by covering with polythene sheets.

6.3 Whether there are any local considerations or urban form & urban design influencing the design criteria? They may be explicitly spelt out.

Ans: The entire project will be developed by abiding the local building rules and regulations set by Asansol Durgapur Development Authority the regulatory authority of Durgapur City Area. The urban form and urban design of the proposed project will be influenced by the local consideration and simultaneously most contemporary from aesthetic and users point of view.

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.

Ans: No anthropological or archaeological sites or artifacts are located nearby.

7. SOCIO-ECONOMIC ASPECTS

Ans: The building blocks will have vertical and horizontal sun shading protection in the form of fins and chajjas. The Consultant : CENTRE FOR SUSTAINABLE DEVELOPMENT, KOLKATA Page 23 of 26 Residential cum Commercial Infrastructure Project at Durgapur, West Bengal Form – IA Developer – Mani Square Ltd.

sun shading devices will be dependent upon the exposure of a particular surface to the sun.

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.

Ans: The external area within the project site will have partial solar lighting arrangements. There also remains possibility for using solar hot water systems over the roofs of individual buildings, if situation demands.

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 West and the Roof? How much energy saving has been effected?

Ans: Yes. The shading devices of individual building block will designed in such a way that it cuts the glare but allow maximum amount of diffused sunlight. Also, the roofs of the building blocks will have adequate thermal insulation in the form of clay tiles over screed concrete. The external walls will have light colour and smooth surface to reduce the solar heat gain and increase the reflectivity of external walls. However, no special care about the east and west walls of any building have been thought because the orientation and layout of the building blocks will differ from place to place within the site. However, outer skin brick walls of 75 / 125 mm thickness will be provided in the building blocks following the elevation or façade design, which may reduce the heat load of external walls.

9.7 Do the structures use energy-efficient space conditioning, lighting and mechanical systems? Provide technical details. Provide details of the transformers and motor efficiencies, lighting intensity and air-conditioning load assumption? Are you using CFC and HCFC free chillers? Provide specifications.

Ans: Energy Efficiency in Air Conditioning – Residential Part The proposed complex is residential in nature, where prime importance is given on natural wind circulation and illumination aspect. Moreover, as the complex has around 60% open space, incoming breezes is considered as a treasure to the residents of the complex. Keeping in that mind, most of the exterior glazing of the proposed building blocks will be openable type. Thus, operable window area within the building will be maximum. Thus, scope of air infiltration through the glazed windows is also maximum. It is expected that air leakage through entrance doors and operable windows (in closed condition) will not exceed 5.0 l/s-m2.

Energy Efficiency in Air Conditioning – Commercial Part A central air conditioning system shall be designed to provide year round thermal environmental control for Hospital Wards, Operation Theatres, OPDs, Guest Rooms of Hotel, Gym, Lobby, Banquet Halls, Pre- Function, Function Rooms, Meeting Rooms, Coffee Shop, Restaurants, Administrative Offices and Back-of- the-House areas, Kitchens, Laundry, Lift cars & Lift machine rooms.

These shall be FRP construction induced draft type. All mechanical equipment such as chilling units, pumps, AHU’s and larger ventilation fans shall be provided with energy efficient motors in order to attain energy savings, since all these equipment shall operate for extended periods of time. Covered Car Park & Mechanical Plant rooms such as HVAC plant room, Pump room and Filtration plant room shall be provided with mechanical ventilation system

9.8 What are the likely effects of the building activity in altering the micro-climate? Provide a self assessment on the likely impacts of the proposed construction on creation of heat island & inversion effects?

Ans: The proposed construction will not alter the micro-climate of the project site and surroundings significantly. Also, it will not have appreciable impact on creation of heat island and inversion effect due to the following reasons: i) Judicial layout of building block within the complex Consultant : CENTRE FOR SUSTAINABLE DEVELOPMENT, KOLKATA Page 24 of 26 Residential cum Commercial Infrastructure Project at Durgapur, West Bengal Form – IA Developer – Mani Square Ltd.

The building block within the complex is laid in such a manner that there remains sufficient amount of external open space between the blocks of adjacent premises so that the air movement does not get interrupted. ii) Reducing the footprint of building blocks Only around 21.55% of the land area will be occupied by building block. Thus, 78.45% of the land area will remain as open space. Therefore, much lesser heat gain will be over the green surface. iii) Selection of Building Materials The building materials will be selected in such a way that the solar heat gain over the vertical surface and roof is minimized. iv) Trees and Vegetation It is already stated that there is no tree within the project site. Moreover, sufficient number of shading trees will be planted inside the project site to reduce the air temperature within the project site and surroundings. v) Reduction in Hard Surface Hard surface in the form of metallic road will be kept minimum. The pavements will be of porous and light coloured material and open joints.

9.9 What are the thermal characteristics of the building envelope? (a) roof, (b) external walls; and(c) fenestration? Give details of the material used and the U-values or the R values of the individual components.

Ans: The U and R values of different components to be used in the project, i.e., glass, wall and roof, are as given in the table below: S.No. Component U-Value R-Value 1 Glass 3.3 W/ms-°C -- 2 External Wall 0.44 W/m2-°C -- 3 Roof 0.263 W/m2-°C --

9.10 What precautions & safety measures are proposed against fire hazards? Furnish details of emergency plans.

Ans: The basic system for Fire Fighting shall be designed as per the provisions of the National Building Code (SP 7: 1983 Part IV Amendment No 3 of January 1997). For the fire protection purpose provision of fire water storage tank of recommended capacity has been made. Water from these reserve tanks will be drawn by electrically driven fire pump and supplied into hydrant ring main and wet riser system. Minor line losses would be made up by an on-line jockey pump. A diesel engine driven fire pump will also be provided as a stand by. The Building will be a fully sprinkled building and the sprinkler heads shall be distributed as per the National Building Code with each sprinkler head.

The building will conform to the provisions of National Building Code as well as the provisions of Fire Fighting Authority, Govt. of Jharkhand building by laws and will be provided with adequate arrangement to overcome fuel hazards to the satisfaction of Authority. Proposed Emergency Preparedness Plan considering the expected fire hazard is enclosed in Annexure – 9.10.

9.11 If you are using glass as wall material provides details and specifications including emissivity and thermal characteristics.

Ans: Glass will not be used as wall material, as preliminarily thought.

9.12 What is the rate of air infiltration into the building? Provide details of how you are mitigating the effects of infiltration

Ans: Most of the exterior glazing of the proposed complex will be fixed and sealed in nature. Operable window area within the building will be comparatively very less. Thus, scope of air infiltration through the glazed windows is minimum in this project. However, there lies scope of air-infiltration through the entrance doors, which will be swinging in nature, and other doors also. It is expected that air leakage through glazed swinging/revolving entrance doors will not exceed 5.0 l/s-m2. Air leakage for other fenestration and doors are expected to be within 2.0l/s-m2.

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.

Consultant : CENTRE FOR SUSTAINABLE DEVELOPMENT, KOLKATA Page 25 of 26 Residential cum Commercial Infrastructure Project at Durgapur, West Bengal Form – IA Developer – Mani Square Ltd.

Ans: Solar energy will be used for paved area and open parking area illumination, as already stated. Solar lighting calculation is given below: Following the SEAC recommendation, 1% total power requirement will be catered by solar power. Solar energy will be used for paved area and open parking area illumination as well as for partial common area illumination. Solar lighting calculation is given below: In our design proposal, total road and open parking area are 37,667.78 sq.m i.e. 405305 sq.ft. Considering street lighting load as 2.5Watt/sq.m or 0.23 Watt/sq.ft (as per Indian Green Building Council Manual), Required lighting load = 405305 X 0.23 = 93,320.15 Watt say 93320 watt Considering diversity factor = 0.80, required lighting load is 93320 X 0.8 = 74,656 watt i.e. 74.65 kW say 75 kW Considering power requirement of each street light as 0.15 kW, number of street light fixture required 75 / 0.15 = 500 nos. 25% of Total Street light fixture to be catered with LED lamps to be catered by solar power. Thus, total number of solar street lighting fixture to be provided is 500X 25% = 125 nos. Solar Power to be used for partial common area illumination is given below; In our project, total connected load as preliminarily assessed is 7723 kW. Total solar energy to be harvest as per SEAC recommendation is 1% of total connected load i.e. 7723 kW X 1% = 77 kW. Out of 77kW, (75/4) or 18.75 kW is being used as outdoor solar illumination. Thus, rest (77 – 18.75) kW i.e 58.25 kW of Solar Energy will be used for partial common area illumination. Or else it may also be connected to the power grid.
