The central government has implemented stringent Stage III measures under the Graded Response Action Plan (GRAP) across Delhi-NCR as the capital's air quality plunged into the 'severe' category on Tuesday. This emergency response comes after a sharp deterioration in air conditions over a 24-hour period.
Rapid Deterioration Triggers Emergency Response
Delhi's average Air Quality Index (AQI) witnessed a dramatic surge from 362 on Monday to 425 by Tuesday morning, crossing the critical threshold that mandates immediate action. The Commission for Air Quality Management (CAQM) identified specific meteorological conditions as the primary cause for this rapid decline.
According to the air quality monitoring body, calm winds combined with a stable atmosphere and unfavourable weather patterns prevented the dispersion of pollutants. These conditions trapped harmful particles close to the surface, creating the hazardous air situation that prompted the emergency measures.
What Stage III GRAP Means for Delhi-NCR
The Sub-Committee overseeing air quality management decided to invoke all actions prescribed under Stage-III of the GRAP framework, which specifically addresses 'Severe' air quality conditions when the AQI ranges between 401-450. These measures take effect immediately across the entire National Capital Region and build upon the restrictions already in place under Stages I and II of the GRAP system.
The decision reflects the government's proactive approach to preventing further deterioration of air quality in the region. By implementing Stage III measures, authorities aim to curb additional pollution sources and protect public health during this critical period of environmental stress.
Broader Implications and Ongoing Measures
This escalation to Stage III represents the most significant anti-pollution intervention implemented this season. The comprehensive approach demonstrates the government's commitment to addressing the air quality crisis through coordinated action across multiple sectors and jurisdictions within the NCR.
The immediate enforcement underscores the seriousness of the current air quality situation and the need for rapid response mechanisms when meteorological conditions turn unfavourable. Residents across Delhi-NCR can expect heightened restrictions and increased enforcement of pollution control measures until air quality shows substantial improvement.
