Introduction of BS norms
The Ambient Air Quality is being monitored across the country under the National Air Monitoring Programme (NAMP) since 1984-85 by the Central Pollution Control Board (CPCB), State Pollution Control Boards (SPCBs)/ Pollution Control Committee (PCCs) and National Environmental Engineering Research Institute (NEERI) which is co-ordinated by the CPCB. There are 580 operating Air Quality Monitoring Stations covering 242 cities, towns and industrial areas in 28 states and 5 Union Territories including 45 metro cities as on 31.10.2014.
Three pollutants, namely, Sulphur Dioxide (SO2 ), Nitrogen Dioxide (NO2) and PM10 (particulate matter having size less than 10 micron) are being monitored at all stations. The monitored data for ambient air as processed by CPCB for the last 03 years (2010, 2011 and 2012) reveals that the levels of fine particulate matter (PM10 – annual average – 60 µg/m3 exceeded the prescribed norms in 42 out of 45 metro cities monitored during 2012.
Emission norms for various categories of motor vehicles are specified in rules 115, 115A, 115B, 115C and 115D of Central Motor Vehicles Rules, 1989 (CMVRs). For four wheeled vehicles, Bharat State IV emission norms have been mandated in the National Capital Region and in the cities of Mumbai, Kolkata, Chennai, Ahmadabad, Hyderabad (including Secunderabad), Bangalore, Kanpur, Pune, Surat, Agra, Sholapur, Lucknow.
