Solid waste would be generated both during the construction as well as during the operation phase. The solid waste expected to be generated during the construction phase will comprise of excavated materials, used bags, bricks, concrete, MS rods, tiles, wood etc. The following steps are to be followed for the management solid waste:

Construction yards are used for storage of construction materials.

The excavated material such as topsoil and stones will be stacked for reuse during later stages of construction.

Excavated top soil will be stored in temporary constructed soil bank and will be reused for landscaping of the Commercial Project.

Remaining soil shall be utilized for the construction activity like development of roads with in the airport land.

8.1 Backup Power Details

There is provision of DG sets of 2500 KVA for power back up in the proposed project. The DG sets will be equipped with acoustic enclosure to minimize noise generation and adequate stack height for proper dispersion.

9.0 STORM WATER DRAINAGE & RAIN WATER HARVESTING SYSTEM

A network of covered/underground storm water drain will be developed to collect rain water runoff from roof tops. Strom water would be channelized to rain water harvesting structure designed to charge the rain water to ground water aquifer. The storm water will pass through the desilting chamber/oil& grease separator before finally discharging to percolation tank. Design details of Rain Water Harvesting structure are given in the table 7. For basement parking, the rainwater from ramps will be collected in the basement storm water storage tank. This water will be pumped out to the nearest external storm water drain

12.0 SEISMICITY

Based on the tectonic features and records of earthquake, a Seismic Zoning map has been developed for the country by Bureau of Indian Standard (BIS). The area under study falls in Seismic Zone-IV. Suitable seismic coefficients in horizontal and vertical directions respectively, will be adopted while designing the structures. Earthquake resistant construction material will be used.

13.0 EMERGENCY LIGHTING

The emergency lights operated on battery power should be provided at appropriate locations – such as corridors, common area, staircase, exit and entrance doors, parking, etc. The transformers will be kept energized and should feed independently alternate rows of lights so that in case of failure of one transformer, there will not be complete darkness.

14.0 FIRESAFETY

Fire Fighting Designed: As per National Building Code 2016/guideline of District fire department.

Fire Tender route with access to each block.

Fire escape staircases as per NBC requirements.

Fire Alarm system

Sand buckets will be placed on each floor of convenient shopping.

15.0 ENVIRONMENTAL POLLUTION MITIGATION MEASURES

15.1 Air Pollution

Increased traffic generation due to project (2708 ECS of parking space proposed for the project is not going to cause significant increase in atmospheric concentration of gases and will not result in heat island formation as adequate landscaping has been provided.

Mitigation Measures for Air Pollution during Construction Stage

The impact on ambient air quality during construction stage around the project site will be

assessed. Various construction activities especially related to handling of loose material



Conceptual Plan


likely to cause generation of fugitive dust will affect the air quality of the surrounding area of

the project site. To minimize such impact following measures shall be taken:

The construction material will be carried in properly covered vehicles.

Construction material will be stored at identified site/temporary godowns at site.

All the loose material either stacked earth or transported shall be provided with suitable covering such as tarpaulin, etc.

Internalroadswillbemaintainedingoodconditionswithregularsprinklingofwater(WB) to curb the dust nuisance to the surrounding

Water sprinkling shall be done at the location where dust generation is anticipated.

Tin sheets will barricade the periphery of the plot.

Mitigation Measures for Air Pollution during Operational Stage

Operation of DG Sets is the only source of air pollution during operational phase. Sufficient stack height will be provided for proper dispersion of pollutants. Also, it is proposed to minimize air pollution by providing plantation as buffer on the periphery of the project site and on the open spaces. An area of 2580 m2 i.e. 10 % of the total area has been kept for plantation purposes.

15.2 Water Pollution

The source of water pollution during construction and operation phase is due to waste water generated from toilets and washing.

Mitigation Measures for Water Pollution during Operational Stage:

Waste water generation and treatment and reuse are dealt in 6.1.

15.3 Noise Environment

It is envisaged that within the proposed project there shall be maximum movement of light motor vehicles like cars and 2-wheelers which will lead to some increase in noise levels. It is proposed to minimize the noise levels by providing plantation as buffer on the sides of internal roads, on the open spaces inside and around the periphery of whole complex. Proper maintenance of the internal roads will also be carried out and Informatory signboards shall be provided to encourage vehicle owners to maintain their vehicle, not to blow horns and follow the emission standards fixed by Government Authorities.

DG sets will be kept in the acoustic chamber and ambient noise will be within the CPCB standard limits. Mitigation Measures for Noise Pollution during Construction Stage Administrative as well as engineering control of noise will be implemented. Isolation of noise generation sources and temporal differentiation of noise generating activities will ensure minimum noise at receiver’s end. To prevent any occupational hazard,



Conceptual Plan


ear muff / ear plug shall be given to the workers working around or operating plant and machinery emitting high noise levels. Use of such plant or machinery shall not be allowed during night hour. Careful planning of machinery operation and scheduling of operations shall be done to minimize such impact. Mitigation Measures for Noise Pollution during Operation Stage

It is envisaged that there shall be maximum movement of light motor vehicles like cars and 2-wheelers which will lead to some increase in noise levels. It is proposed to minimize the noise levels by providing plantation as buffer on the open spaces and around the periphery of whole complex. Informatory signboards shall be provided to encourage vehicle owners to maintain their vehicle, not to blow horns and follow the emission standards fixed by Government Authorities
