EIA Studies of 3 Pre-Identified Hazardous Waste Disposal Sites in ...

Rapid EIA Studies of 3 Pre-identified Hazardous Waste Disposal Sites in NCT - Delhi:
4.15 FOREST AREA
Page No.122
Only Bawana old site falls under protected forest area. Bawana Forest is about 1 km
from the proposed site. The other three sites do not fall under any notified forest
area.
4.16 NATURAL HAZARDS
Natural hazards comprises of flood, 4.36 shows the natural hazards in NCT- Delhi.
• Flood prone areas
There are two types of flood plain, one older flood plain and other newer flood plain
as shown in Fig 4.19. Older flood plain has erosional characteristics whereas newer
flood plain has depositional characteristic. The older flood plain of Yamuna is prone
to annual and periodic floods. The areas most affected are west of Shahadra in trans
Yamuna area and between Narela - Wazirabad and Redfort - Okhala barrage in the
cis Yamuna area. Fig 4.36 shows area prone to annual floods and areas prone to
occasional floods. None of the proposed sites fall under any of these flood plains.
• Water logged areas and other unstable lands
Fig 4.37 shows the seasonally/perennially water logged / tract in NCT- Delhi. Water
logging is a common phenomenon in the immediate vicinity of canal and large fluvial
features e.g. near Model Town, Adarsh Nagar etc. Fig 4.37 also shows zones having
saline brackish ground water, bad land, groundwater overdraft zones , etc. All the
four proposed sites fall outside these zones.
• Siesmicity
NCT of Delhi is categorised in the seismic zone IV as shown in Fig 4.38. Zone IV is
charaterised by a significantly high intensity of seismic activities. This class has a
fairly high probability of earthquake shocks measuring 5 - 6 on the richter scale, low
probability of shocks of 6 - 7 on the richter scale and, occasional occurrence of
shocks of 7 - 8 on the richter scale. Fig 4.39 shows the epicentre of few of the past
earthquake shocks occurred in NCT - Delhi.
