Only 5% of large building sites are on the dust portal, checks to track all

The state pollution board will survey the city to identify any construction and demolition projects that aren't registered on the government's portal that was created to monitor all environmental norms being followed.

Construction sites larger than 500 sqm must install PM2.5 and PM10 sensors that send a live feed to the online portal, according to directives by the Commission for Air Quality Management (CAQM) in NCR.

So far, not a single construction site in the city has installed the mandatory sensors, officials of the Haryana State Pollution Control Board (HSPCB) said on Tuesday.
