Delhi’s overall Air Quality Index (AQI) clocked at 399 today as per the 4PM AQI Bulletin provided by Central Pollution Control Board (CPCB). In view of significant deterioration in air quality of Delhi-NCR in last 24 hours, the Sub-Committee for invoking actions under the Graded Response Action Plan (GRAP) of the Commission for Air Quality Management in NCR & Adjoining Areas (CAQM) held an emergency meeting today. During the meeting, the Sub-Committee comprehensively reviewed the air quality scenario in the region as well as the forecasts for meteorological conditions and air quality index of Delhi. While assessing the overall air quality parameters, the Sub-Committee noted that due to extreme unfavorable meteorological conditions the overall air quality of Delhi has deteriorated over last few hours and there is an increasing trend further in the coming days as per the Air Quality forecast of IMD/IITM. Therefore, it is considered necessary to put Stage-III of GRAP back in place with immediate effect in the entire NCR in an effort to prevent further deterioration of air quality in the region.

Based on earlier decisions of the Sub-Committee on GRAP, actions up to Stage-I and Stage-II of the GRAP are already in force vide orders dated October 5, 2022 and October 19, 2022 respectively. Actions under stage-III of GRAP were invoked on 04.12.2022 in the NCR, pursuant to a significant deterioration in the average air quality of Delhi and the Sub-Committee in its meeting held on December 07, 2022 reviewed the air quality scenario in the region and based on the improvement in the overall AQI of Delhi, the Sub-Committee revoked its order dated 4th December, 2022 vide order dated 7th December, 2022.

As per the dynamic model and weather/ meteorological forecast, the overall AQI of Delhi is expected to slip into ‘Severe’ category owing to calm wind and stable atmospheric conditions and is expected to deteriorate further, therefore, in an effort to prevent further deterioration of air quality in the region, the Sub-Committee has decided that all actions as envisaged under Stage III of the GRAP – ‘Severe’ Air Quality (DELHI AQI ranging between 401-450), be implemented in right earnest by all the agencies concerned, with immediate effect in the entire NCR. This is in addition to the preventive/ restrictive actions already in force under Stage-I and Stage-II of GRAP.

Accordingly, a 9-point action plan as per Stage-III of GRAP is applicable with immediate effect from today in the entire NCR in addition to preventive/ restrictive actions under Stage-I and Stage-II of the GRAP which are already in place. This 9-point action plan includes steps to be implemented/ ensured by different agencies and PCBs of NCR and DPCC. These steps are:

  1. Intensified frequency of mechanised/ vacuum-based sweeping of roads.
  2. Daily water sprinkling along with use of dust suppressants, before peak traffic hours, on roads and right of ways including hotspots, heavy traffic corridors and proper disposal of the collected dust in designated sites/ landfills.
