GRAP-4 Reimposed In Delhi As Pollution Level Reaches 'Severe' Category

The curbs under Stage 4 of GRAP include a ban on all construction and demolition activities, including public projects, and on the entry of trucks carrying non-essential goods into Delhi.

The centre's air quality panel for Delhi-NCR imposed restrictive measures under stage-IV of the air pollution control plan as the air quality in the national capital dipped to 'Severe' category on Monday evening. 

 

The curbs under Stage 4 of the Graded Response Action Plan (GRAP) for winters include a ban on all construction and demolition activities, including public projects such as highways and flyovers, and on the entry of trucks carrying non-essential goods into Delhi.

"Delhi’s average AQI rose to 399 at 9PM tonight and breached the 400 mark at 10PM. Considering the rise in the AQI of Delhi owing to highly unfavourable meteorological conditions and absolute calm wind conditions, the CAQM Sub-Committee on GRAP called for an emergency meeting. The Sub-Committee decided to impose Stage-IV (‘Severe+’ Air Quality) of the GRAP schedule (issued on 13.12.2024) in the entire NCR, with immediate effect," the the Commission for Air Quality Management (CAQM) said in a post on X.

 

The move comes hours after the central panel imposed GRAP-3 in the capital amid a sharp dip in air quality. Delhi’s 24-hour average Air Quality Index (AQI) was recorded at 379 (very poor) at 4 pm on Monday, up from 294 in the “poor” category on Sunday. However, the AQI slipped to 'severe' category on Monday evening with the pollution levels reaching 401.

 

Meanwhile, the minimum temperature in the capital fell to 4.5 degrees Celsius, 4.1 degrees below normal, according to the weather department. This is the fourth time in December when the minimum temperature dropped below 5 degrees Celsius, with cold wave conditions observed in Pusa, according to the India Meteorological Department.
