The Commission for Air Quality Management (CAQM) has officially clarified that Stage IV of the Graded Response Action Plan (GRAP) has not been implemented in Delhi and the National Capital Region. This clarification comes amid widespread speculation about additional pollution control measures being activated in response to the deteriorating air quality conditions.
Official Clarification on GRAP Implementation Status
The air quality regulatory body issued a definitive statement addressing the current status of anti-pollution measures. The Commission for Air Quality Management explicitly stated that Stage IV of GRAP has not been invoked in the Delhi-NCR region, despite the severe air quality conditions being experienced in the capital and surrounding areas.
This clarification becomes particularly significant given that Delhi's air quality index has consistently remained in the 'severe' category in recent days. The Air Quality Index (AQI) readings across multiple monitoring stations have shown alarming levels of particulate matter, creating health concerns for residents and prompting discussions about additional measures.
Current Anti-Pollution Measures in Effect
While Stage IV has not been activated, the CAQM emphasized that earlier stages of the Graded Response Action Plan remain actively implemented. Stages I, II, and III of GRAP continue to be enforced across the National Capital Region as part of the comprehensive strategy to combat air pollution.
The Commission highlighted that these existing measures include restrictions on certain categories of vehicles, enhanced public transportation services, and specific controls on industrial operations and construction activities. These steps represent the current framework of pollution control actions being undertaken by authorities.
Understanding the GRAP Framework
The Graded Response Action Plan represents a structured approach to air quality management, with specific measures triggered at different AQI thresholds. Stage IV, which constitutes the most severe category of response, includes stringent measures such as potential restrictions on diesel-powered four-wheelers and additional limitations on trucks entering Delhi.
The decision to implement Stage IV measures requires careful consideration of multiple factors, including meteorological conditions, pollution source contributions, and the effectiveness of existing control measures. The CAQM's clarification indicates that while air quality remains concerning, the situation has not yet reached the threshold necessitating Stage IV activation.
The Commission continues to monitor the situation closely, with regular assessments of air quality data and meteorological forecasts informing their decisions about appropriate response levels. Residents are advised to stay informed through official channels and follow recommended health precautions during periods of poor air quality.
