POINTWISE COMPLIANCE TO QUIRIES RAISED DURING

11th EAC (Infra-II) MEETING

Point No.1: Status of application of the project proposal in SEIAA, Maharashtra.

Compliance: The application is not considered at SEIAA, Maharashtra as the

SEAC MMR’s tenure is over and there is no committee for appraisal of projects.

Hence, we have applied to MoEF&CC, Delhi on 28.10.2016.

Point No.2: Copy of application submitted for clearance from NBWL.

Compliance: As per the ESZ notification of Sanjay Gandhi National Park (SGNP),

vide no. S. O. 3645 (E) dated 05.12.2016, our project site is outside of ESZ i.e.

(100 m); hence clearance from the Standing Committee of the National Board for

Wildlife is not applicable for our project.

Point No.3: Present landuse of the proposed project site.

Compliance: The project site is under residential use as per the DP of MBMC

(Mira Bhayander Municipal Corporation). The project location on the DP is

shown in the figure 1.

Point No.7: Layout of parking plan indicating entry and exit points of vehicular

movement as well as traffic management plan. Highlight the fire tender pathway.

Compliance: The layout showing entry and exit points, driveways, parking slots,

vehicular movement and fire tender movement is shown in figure 4.

The proposed driveways will provide a safe and efficient connection to the

external road network

The traffic from the project will exit and enter from 18 m wide internal DP

road.

The entry and exit points will be manned by trained security staff. They

will manage the traffic at these points and prevent bottlenecks.

Entry and exit lanes do not cross and exit is after entry. Exit and entry are

segregated.

All the driveways are marked with guiding signs for better circulation.

All the driveways/aisles are straight with no dead ends

The minimum width of the driveway is 6m for efficient traffic circulation

and proper fire tender movement

Driveway will have speed humps at every 100 m, before a turn and before

entry/exit. This will control the speeding of vehicles within the project

premises.

Proper directional arrows will be used inside the parking bays

The parking plans and fire tender movement plan are given in the following

figure.

Point No.8: Details of source of water supply alongwith permission to be

submitted.

Compliance: Water supply for the project will be received from MBMC. The

commitment letter from MBMC is given in the following figure 5:

Point No.9: Excess treated sewage disposal plan/scheme to be submitted.

Compliance: Excess treated water from our project will be disposed in the

proposed Municipal sewer lines. The letter regarding the proposed sewerage

network of MBMC and its connection to the project site is given in the letter

given in figure 6.

Figure 6: MBMC letter regarding Sewer lines

Point No.10: Assessment of ground level concentration of pollutants due to DG

set (800 KVA).

Compliance: Assessment of ground level concentration of pollutants due to DG

set of total 800 kVA is done using dispersion modelling for estimated

concentrations of SO2. The DG set operation will contribute towards the air

pollution. These DG sets have been provided to take care of power availability

during power failure from MSEDCL. However in the project area 24 hrs

electricity is supplied, but on a precautionary basis the above DG sets have been

proposed in case of any emergencies arising out of routine power failure. The

Umiya Developers

11th EAC MoM reply Page 11

impact of the DG sets on the environment has also been studied using

mathematical model for ascertaining the gaseous pollutant impact.

The results of the mathematical model indicate that the maximum incremental

increase in the SO2 concentration is 2.5 ug/m3. The isopleths of predicted SO2

concentrations is given in the following figure. This is confined to a small area of

1000 m in and around the project site. The predicted concentrations from the

model will not lead to alter the baseline concentrations as it is well within the

norms stipulated and also as the DGs will be used only during emergency.

Figure 7: Isoplethes of predicted SO2 concentration

Point No.11:Effort shall be made to reduce capacity of DG set upto 500 KVA and

remaining standby power shall be met from solar energy.

Compliance: We will reduce capacity of DG set upto 760 KVA and remaining

standby power of 140kVA will be met from solar energy i.e. Solar PV panels &

Solar trees. Kindly refer point no. 15 for solar power generation calculations.

Point No.12: Treatment scheme for sewage and its recycling mode.

Point No.13: Details of rain water harvesting system to be furnished. Clarity on

recharge pits, storage systems for rain water and use of appropriate filtration

system for collected rain water to be detailed.

Compliance: The rooftop rainwater will be stored in Rain Water Harvesting

tanks after filtration. The roof top Rain water harvesting potential project is

57m3/day & the provision of 9 Rainwater Harvesting tank having capacity 120

m3 will be provided. The cross section of Rainwater harvesting unit is given in

Point No.14: Calculation on sizing of solar water heating systems to be

furnished.

Compliance: We are not providing solar hot water panels as the terrace area

will be utilized for provision of PV panels to provide energy for for 2 solar

powered lights and one fan in each flat and emergency backup.

Point No.15: Details on solar lighting for common areas as well as for two light

and one fan in each flat to be provided.

Compliance: We have proposed solar panels to provide 2 solar powered lights

and one fan for each of 765 tenements. The calculations for PV panels are as

following:

SOLAR PV PANEL CALCULATION

On average photovoltaic (PV) solar panels will produce 10-13 watts per square

foot of solar panel area. 10 kW/m2 of solar power generation is considered for

following calculations:

Total Terrace Area = 2863.91 m2

Actual usable terrace area for Solar Panels = 1718.34 m2 (60% of total

terrace area)

Power requirement of 2 lights and 1 fan

Connection for 765 tenements =80 W x 869= 61.2 kW approx.

Area required for generation of 1kW is 10m2

Hence area required for generation of 61.2 kW =612 m2

Area available for PV panels = 1106 m2

Solar Power generation = 111 kW = 140 kVA

Thus 140 kVA of Solar power will be supplied to grid and used as stand by

power during emergency.

Point No.16:Solid waste management plan alongwith area earmarked for solid

waste management scheme.

Compliance: Solid waste management plan along with area earmarked for solid

waste management scheme and the location of the SWM in layout is shown in

following figure 11 .

Point No.17: Management of excavated soil. Pollution control measures to be

taken to control fugitive emission during construction phase including marble

/stone cutting.

Compliance: Excavated soil will be used for the Road pavement & site leveling.

Fugitive emission during construction phase will be control by barricading &

plantation along the plot boundary, water sprinkling at regular interval to arrest

Air Bourne-dust, Use of Ready Mix concrete to avoid excessive movement of

vehicles on the site. Use of PPE such as ear plugs and masks for labours will be

made mandatory wherever there are excess emissions. Precut vitrified tiles will

be used for flooring. Tile cutting will be done within the building and will be

done using water so there will not be any considerable fugitive emission.

Point No.18: Details energy conservation measures to be taken. all points

mentioned in the proposal such as orientation to support reduced heat gain, use

of ASHRAE 90.1, use of ECBC compliant envelope measures to be supported

through drawings and details in the proposal.

Compliance: Internal and external lighting design will be provided as required

by ECBC which will have Lighting Power Density as per space requirements.

Umiya Developers

11th EAC MoM reply Page 17

The project would provide 20% lower LPD than as specified in ECBC, to achieve

energy saving, while providing the required illumination levels, by using high

efficacy lighting.

Tree plantation is proposed along the periphery of the site ensuring adequate

buffer and reducing heat gain by the building so that the buildings will remain

naturally ventilated.

The project design will use high energy performing building materials which

would have low U value (Thermal Conductance) as compared to the conventional

materials. The external wall of building would use fly ash blocks, which will have

mandatory SHGC as required by ECBC.

Point No.19: Layout plan indicating Greenbelt alongwith area earmarked to be

provided.

Compliance: Layout plan indicating Greenbelt is given in the figure 12:
