7.0 SOLID WASTE GENERATION, COLLECTION, TRANSPORT AND DISPOSAL
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 LANDSCAPE & SHELTERBELT DEVELOPMENT
About 10% of the plot area will be developed as green area. 10.0 PARKING FACILITIES
Adequate provision will be made for parking at the proposed commercial Project. There shall also be adequate parking provisions for visitors so as not to disturb the traffic and allow smooth movement at the site.
10.1 Parking Details Table: 8
Required Parking 3ECS/100 Sqm
Parking Required 3385.56 ECS
Proposed Parking 3386 ECS
11.0 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.
12.0 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.
13.0 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.

14.0 ENVIRONMENTAL POLLUTION MITIGATION MEASURES
14.1 Air Pollution
Increased traffic generation due to project (3386 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
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 1870 m2 i.e. 10 % of the total area has been kept for plantation purposes.
14.2 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.
14.3 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, 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
DG sets will be kept in the acoustic chamber and ambient noise will be within the CPCB standard limits.
