proposed integrated complex for delhi judicial academy

Rapid Environmental Impact Assessment (REIA) Study for Proposed Integrated Complex for Delhi Judicial Academy,
National Law School, and National Institute for Mediation & Conciliation at Dwarka, New Delhi
The figure shows the annual average of RSPM levels over the city. It is clear that RSPM
levels have reduced to 21.4 % in the year 2001 and remained almost constant in the year 2002 as
compared to year 2000. The increase could be due to adverse meteorological conditions in 2002.
Carbon Monoxide (CO)
The annual average CO levels as shown in the figure indicate constant reduction of CO levels at
ITO intersection. The observed concentration of CO came down from 4183 µg/m 3 in Year 2001 to
3258 µg/ m 3 in Year 2002. This could be attributed to the stringent vehicular emission norms, fuel
quality up-gradation and development of better engines. Though the annual average levels of
Carbon Monoxide continue to be above the danger mark of 2,000 µg / m 3 , there has been a gradual
decline.
4.5.2 Ambient Air Quality Survey
The existing ambient air quality in the core zone (local and immediate vicinity) of the proposed
project site has been assessed during summer 2006 through a network of four ambient air quality
stations. The prime objectives were to establish existing local background levels and baseline air
pollution status. The ambient air quality monitoring network has been designed keeping in view the
available predominant wind direction and wind speed in the project area. One station was kept at
the centre and the other three at about 120 o direction apart. The sources of air pollution in the
project area are mainly vehicular traffic, construction activities, and general human activities.
The following points were also taken into consideration in designing the network of sampling
stations:
• Locations with increasing mixed residential and commercial development within the study
area.
• Locations near Schools, hospitals and other sensitive areas within the study area.
• Locations which are representative of land-use categories.
• Representation of cross sectional distribution in downward direction.
• Locations where the baseline ambient air quality are established such that it can be
resurveyed in the future to monitor changes in the ambient environment.
• Locations within the project area with the least interference of anthropological activities.
