GRAP 4 Restrictions: The strictest anti-pollution measures have been reimposed in the national capital, Delhi, after the Air Quality Index (AQI) dangerously approached the ‘Severe+’ category. The Commission for Air Quality Management announced the re-implementation of Stage-IV measures under the Graded Response Action Plan (GRAP) in view of the rapidly deteriorating situation.
On Saturday evening at 4 PM, Delhi’s AQI was recorded at 400, which falls in the ‘Very Poor’ category. However, in just four hours, it rose to 428, dangerously close to the threshold of the ‘Severe+’ category (above 450). Therefore, several activities have been banned in the capital under GRAP-4.
Commission for Air Quality Management: What is the reason for increase in AQI?
According to officials, the sharp increase in the AQI is primarily due to a Western Disturbance, unfavourable meteorological conditions, and poor dispersion of pollutants. The Sub-Committee of the Commission for Air Quality Management stated in its notification that, to prevent further deterioration of the situation, it was unanimously decided to implement Stage-IV measures as a precautionary step.
Severe Air Quality: GRAP-3 restrictions were already in effect
Restrictions under Stages 1, 2, and 3 of the Graded Response Action Plan (GRAP) are already in effect in Delhi-NCR. In addition, stricter restrictions have been imposed under Stage 4, or ‘Severe Plus,’ to prevent further deterioration of air quality. This includes a ban on construction activities and strict monitoring of polluting activities. This step has been taken as a precautionary measure to prevent further increase in pollution levels.
