Rapid EIA Studies of 3 Pre-identified Hazardous Waste Disposal Sites in NCT - Delhi

Impact on soil / land Environment
Construction phase includes activities like excavation, roads & building (office,
laboratories) construction, electrification etc. These activities will effect the quality of
topsoil. However, development of green belt will improve the quality of topsoil. As the
site recommended is a barren land not suitable for agriculture, there is no adverse
impact on the landuse of the site.
During the operation phase leachate is generated which is proposed to be treated in
leachate treatment plant before discharging either into the land or surface water
body. Also an impermeable liner system at the base of the facility will prevent
percolation of leachate into the soil. The risk of contamination of the soil by the
leachate is therefore reduced.
After the closure of the site, there will no surface run off, therefore there will be no
impact on soil/land. Further, a vegetation cover is recommended at the top of the
cover liner . This will improve the quality of topsoil in the area. The vegetation cover
will also prevent the soil erosion and will improve the landscape.
Impact on Environmental Health
During the construction phase, the generation of dust may have impact on the health
of the workers. However, periodic spray of water is proposed to minimise the dust
generation. Although the site is 1 Km away from the nearest settlement, a green belt
around the facility is proposed to reduce the impact on health.
During, operation phase, transportation of waste through the populated residential
areas may pose risk of exposing the pollutants to the public. The site is around 30 -
40 km away from the industrial estates/areas. Therefore, the transportation of
hazardous wastes is proposed in closed/covered vehicle. Further, following
measures are proposed:
Select a transportation route passing through minimum residential areas
Proper maintenance and regular washing of the vehicles transporting the waste.
Use of protective gears while working in the facility
During closure/postclosure phase, there will be very less dust generation. Therefore,
the impact is minimum. However, it is proposed to use protective gears while
working at the site. This is a short term impact.
Impact on Socio-economics
Development & operation of facility will increase the job opportunities and will results
in improvement of infrastructural facilities in the area. This is a positive long -term
impact.
