The Commission for Air Quality Management (CAQM) directed the governments of Delhi, Haryana, Uttar Pradesh and Rajasthan on Friday to develop an online mechanism to monitor construction agencies’ dust mitigation measures in the national Capital region (NCR) and adjoining areas.

In a statement, CAQM said that the introduction of a robust online mechanism for monitoring dust mitigation measures was necessary to ensure strict implementation of construction and demolition waste management rules.

“As per the directions of CAQM, all construction projects ongoing on plot area equal to or greater than 500 square metres in the NCR have to mandatorily register on the web portal. Along with this, provision for video fencing equipped with remote connectivity technology will have to be incorporated on the web portal for effective and round-the-clock monitoring of compliance of dust mitigation measures by the project proponents,” the statement read.

It added, “Further, the project proponents are required to install reliable and low-cost PM2.5 (particulate matter with diameter less than 2.5 micrometres) and PM10 (particulate matter with diameter less than 10 micrometres) sensors at construction sites.”

Rai says CP smog tower cut pollution by 80%

The Delhi government’s first smog tower installed at Connaught Place has reduced air pollution in the vicinity by up to 80%, environment minister Gopal Rai claimed on Friday.

While inspecting the smog tower installed at Baba Kharak Singh Marg in CP on Friday, Rai said the preliminary reports of the filtered air quality shows that the smog tower was cleaning up to 80% of the polluted air in the area around it.

“We have constituted a 16-member committee today (Friday) to closely monitor the smog tower. The committee will submit three reports to the Delhi government, at an interval of three months each... On the basis of the report, the government will decide whether to install more smog towers,” said Rai.

“The committee will have five members from the Delhi Pollution Control Committee (DPCC). Apart from this, five members from IIT-Bombay, three from NBCC (India), and three from Tata Project Limited will join the panel,” he said.

Rai said that according to the sensors installed around the smog tower, around 8am on Friday, the PM2.5 level fell from 151µg/m3 fell to 38µg/m3.
