Improving Air Quality in the Major Cities
Ozone has been included as one of the pollutants in National Ambient Air Quality Standards (NAAQS) in November, 2009 so as to ascertain the ambient air quality. The ambient air quality standards for Ozone are prescribed as 180 microgramme/cubic metre (hourly average) and 100 microgramme/cubic metre (eight hourly average). The Central Pollution Control Board in association with State Pollution Control Boards and Pollution Control Committees for Union Territories has started monitoring the ground level Ozone and limited data is available for eight cities, namely, Delhi, Hyderabad, Faridabad, Ahmedabad, Mumbai, Lucknow, Agra and Varanasi. It is too early to predict the trend of Ozone in ambient air. The Energy and Resources Institute (TERI) has taken up a collaborative study in which Ozone levels are estimated by using modeling techniques. It is an ongoing project and preliminary findings are available.

The fresh steps taken by the Government include notification of ambient air quality standards for Ozone under the Environment (Protection) Act, 1986 and development of standard monitoring protocol therein. The other steps taken to improve the air quality in cities include, inter alia, strengthening of public transport; implementation of Bharat Stage-III/IV emission norms for new vehicles in select cities; supply of cleaner fuel as per Auto Fuel Policy; emission standards for Cashew Seed Processing Industry, Plaster of Paris Industry, Incinerators for Dyes & Dyes Intermediates, Incinerators for Organic Chemicals Manufacturing Industry, Iron Ore Mining, Rubber Industry, Copper Lead Or Zinc Smelters and Pesticide Industry; and temporary moratorium for new/expansion projects in 43 critically polluted areas/clusters across the country.

This information was given by the Minister of State for Environment and Forests (independent charge) Shrimati Jayanthi Natarajan in a written reply to a question by Shri Moinul Hassan in Rajya Sabha today.
