Most air pollution complaints relate to construction & demolition activities, CPCB informs SC

The Central Pollution Control Board (CPCB) informed the Supreme Court on Monday that "highest number" of air pollution complaints in the Delhi-NCR pertain to construction and demolition activities, followed by burning of waste and road dust.

Unpaved roads, traffic congestion and industrial emissions constitute other sources of pollution.

In an affidavit filed in the top court, the CPCB has said that spatial distribution of different types of air pollution complaints in Delhi-National Capital Region (NCR) indicated that the construction and demolition related pollution problem was more prominent in western and south-western parts of Delhi.

It said that while incidents of waste burning were highest in the eastern part of the city, in trans-Yamuna area, incidents of industrial emissions and illegal industrial activities were prominent in north-west areas followed by north-eastern part of Delhi.

The board said that garbage dumping incidents were high in eastern part of Delhi.

"As per analysis of complaints during clean air campaign, highest number of air pollution incidents relates to construction and demolition activities, followed by burning of waste, road dust, unpaved areas/roads, traffic congestion and industrial emissions," said the affidavit, which was filed before a bench headed by Justice Madan B Lokur.

With regard to the observation that Sameer App, which provides hourly update of national air quality index (AQI), crashes after lodging complaint of pollution, the board said that it is operational since 2016 and has been functioning satisfactorily.

"However, the complaints lodged on Sameer (App) will not get resolved automatically unless the agencies responsible respond to the same after taking necessary corrective actions," it said.

"Out of 3,337 complaints received on Sameer App during November 1 to November 24 this year, 923 complaints were resolved while 1,248 complaints were attended, 349 complaints were under investigation and 817 complaints are not yet attended by nodal agencies," the affidavit said.
