Meanwhile, the Commission for Air Quality Management in NCR and adjoining areas has intensified its efforts to ensure enforcement and compliance with its directions in view of deteriorating air quality in Delhi.
The Commission has issued closure directions to 45 coal-based industrial units in Rajasthan. Further, 32 coal-based units (9 in Haryana and 23 in UP) have been closed down permanently. 48 units (8 in Haryana and 40 in UP) have temporarily suspended their operations till these units are converted to approved fuels.
The Graded Response Action Plan (GRAP) sub-committee decided to implement Stage III of GRAP in the entire NCR in a move to prevent further deterioration of air quality.
“Under this, all construction work will be banned except for special projects like Central Vista and other projects of national need,” read the official press release from Commission for Air Quality Management in NCR and Adjoining Areas.
While comprehensively reviewing the overall air quality parameters during the meeting, the Commission noted that due to unfavourable meteorological conditions with slower wind speed and sudden spike in farm fire incidents, it is considered necessary to implement Stage III of GRAP with immediate effect in the entire NCR.
