The Centre’s air quality monitoring panel revoked Stage III measures under the Graded Response Action Plan (GRAP) on Friday, citing a notable improvement in Delhi’s air quality.

Favourable weather, including persistent rainfall, has played a pivotal role in reducing the Air Quality Index (AQI) to 334 as of 7 PM on December 27, shifting it from the ‘severe’ to ‘poor’ category.

“Given the marked improvement, measures under Stage III of GRAP are being withdrawn,” the Commission for Air Quality Management (CAQM) stated.

While Stage III restrictions have been lifted, measures under Stages I and II remain in effect to ensure sustained air quality levels. “We are committed to preventing a relapse in AQI deterioration. Strict implementation of Stage I and II measures will continue,” said a statement from the panel.

GRAP is a framework of emergency actions designed to combat air pollution in Delhi-NCR based on AQI levels. According to earlier Supreme Court directives, Stage III measures are imposed when AQI surpasses 350, and Stage IV is introduced beyond 400. Both stages were implemented on December 16 when AQI levels soared to 401.

The highest-level restrictions under Stage IV were revoked on December 24 as air quality began to improve. Officials anticipate the AQI will remain in the ‘poor’ category (200-300) in the coming days, supported by ongoing favourable weather conditions.

Despite the rollback of Stage III, construction and industrial activities previously suspended due to violations will remain halted unless explicitly permitted by authorities.

To maintain air quality gains, citizens have been urged to adhere to GRAP’s Citizen Charter. The CAQM stressed its ongoing vigilance. “We continue to closely monitor the situation and will implement additional measures if necessary,” the panel assured.
