The Commission for Air Quality Management (CAQM) Sub-Committee on the Graded Response Action Plan (GRAP) has decided to revoke Stage-III restrictions across the National Capital Region (NCR) following a significant improvement in Delhi’s air quality.
Key Decisions
- Stage-III Revocation: Based on improving air quality and forecasts from the Indian Meteorological Department (IMD) and Indian Institute of Tropical Meteorology (IITM), the Sub-Committee unanimously decided to lift Stage-III restrictions.
- Stages II and I Remain Active: Preventive measures under Stages II and I of GRAP will continue to be implemented, monitored, and intensified to avoid a resurgence of severe pollution levels.
- Construction Activity Ban: Specific construction and demolition sites that were issued closure orders for non-compliance with statutory guidelines will remain shut unless explicitly permitted by the CAQM.
Background
Stage-III and IV restrictions were initially invoked on January 15, 2025, when Delhi’s AQI surged past 350 and showed signs of further deterioration. Stage-IV restrictions were lifted on January 16 after AQI levels dropped to 302. However, Stage-III measures, which include bans on certain industrial and construction activities, were retained as a precaution.
Future Monitoring and Public Advisory
The Sub-Committee emphasized its commitment to closely monitoring air quality and meteorological forecasts to make timely decisions. Despite the revocation of Stage-III restrictions, citizens are urged to adhere to the GRAP citizen charter and contribute to maintaining improved air quality.
The CAQM has cautioned that winter weather conditions can cause abrupt changes in air quality. The revised GRAP schedule is available on the Commission’s official website for public reference.
This decision provides relief to stakeholders impacted by the restrictive measures while ensuring continued vigilance to prevent a relapse into severe air pollution levels.
