Haryana State Pollution Control Board plans its first study to find sources of pollution 

Gurugram: Nov 29, 2019 (Times of India)    

GURUGRAM: For the first time, the Haryana State Pollution Control Board (HSPCB) is planning to carry out a study on the sources of air and noise pollution in four severely polluted cities of Haryana — Gurugram, Faridabad, Sonipat and Panipat.

The HSPCB has released expressions of interest (EOI) for source apportionment and emission inventory study on levels and sources of pollution in the state. The board has invited educational and research organisations to come forward and carry out the study for one and a half years, according to EOI, a copy of which is with TOI.

The study will create emission inventories for each city, giving the main sources of air pollution in addition to each sector’s contribution to the overall load. The study will also prescribe cost effective measures to check air and noise pollution in the four cities.

Some of the objectives of the study are to identify ground-level concentration of pollutants, hotspots, to select appropriate emission factors for vehicular and non-vehicular sources of pollution, to prepare inventory for different air pollutants, their emission rate and pollution loads and to conduct source apportionment studies for PM10 and PM2.5. Overall, the study will assess the impact of sources on ambient air quality.

While such studies have been carried out in Delhi, this is the first that the studies have been proposed for Gurugram and Faridabad. “Since, air quality in urban areas is affected by a variety of complex sources, detailed scientific studies are required for identification of major sources, assessing their contributions to urban air pollution and suggest mitigation measures taking into consideration the techno-economic feasibility and other social factors. Accordingly, this study has been initiated to promote and demonstrate a more rational and proactive approach to air quality management in urban areas,” said a senior official of HSPCB.

He added that the study will help in taking suitable measures to control air pollution since meteorology, topography and typology of air polluting sources is different in all cities.

The experts welcomed the step. “For Gurugram, such study is very important and I would welcome such step. Broadly speaking, the study aims at finding out contribution of different sectors and activities — automobile industry, construction activities, vehicular emissions, among others —as source of pollution. The study will make it easier to ascertain relative percentage of each source. For example, how much industries are contributing to air pollution and what kind of industries are contributing to air pollution. This will help in understanding which industry should be shut, when and for how long. I think all graded response action plan (GRAP) measures are based on such studies only. We have seen positive impact of such studies in places like Delhi,” said Niranjan Raje, former member of EPCA and chairman of the committee for source apportionment study carried out in Delhi, Bangalore, Mumbai and Chennai.

The move came after Gurugram was included in the National Clean Air Programme in February this year.

The initiative is a part of a comprehensive action plan for clean air in Gurugram , Faridabad, Sonepat and Panipat in the state.
