Delhi-NCR Hits Severe Air Quality: GRAP III Restrictions Now in Force
CAQM implements GRAP Stage 3 in Delhi-NCR to combat severe air quality before Diwali, banning certain vehicles and construction.
In a critical move to prevent a total environmental collapse just days before the Diwali festivities, the Commission for Air Quality Management (CAQM) has invoked GRAP III restrictions Delhi-NCR. The decision, made by the Sub-Committee on the Graded Response Action Plan (GRAP), comes as the National Capital Region grapples with rapidly deteriorating air quality that is threatening to push the city into a health crisis.
Air Quality Plummets to 'Severe' Levels
The emergency measures were triggered following alarming data from the Central Pollution Control Board (CPCB). While Delhi's overall Air Quality Index (AQI) was recorded at 382—placing it in the 'very poor' category—several hotspots across the city have already breached the 'severe' threshold.
Monitoring stations have reported frightening numbers:
- IIT Delhi and Rohini: 474 AQI
- Punjabi Bagh: 465 AQI
- RK Puram: 443 AQI
- ITO: 422 AQI
- Firoz Shah Road: 420 AQI
- India Gate: 403 AQI
According to CPCB standards, an AQI between 301 and 400 is 'very poor', while any reading between 401 and 500 is classified as 'severe'.
What Does GRAP Stage III Mean for Residents?
The transition from Stage II to Stage III introduces high-impact measures designed to act as a "circuit-breaker" to stop the air quality from sliding into the most dangerous 'Severe+' category (Stage IV). These restrictions apply to Delhi and adjoining districts in Haryana, Uttar Pradesh, and Rajasthan.
Vehicle Bans and Transport Changes
To curb tailpipe emissions, strict bans are now in place for BS-III petrol and BS-IV diesel four-wheelers across Delhi and specific NCR districts. Additionally, the government has tightened rules for non-Delhi-registered diesel commercial vehicles and older light or medium goods vehicles entering the capital.
To compensate for these bans and discourage the use of private cars, authorities are increasing the frequency of Metro trips and deploying more buses on the roads.
Construction and Industrial Shutdowns
Dust is a primary contributor to the toxic haze. Consequently, all non-essential construction activities that generate high levels of dust—including major excavations, earthwork, demolition, and road construction—have been suspended. Only essential projects are permitted, and they must adhere to rigorous dust-mitigation protocols. Stone crushers and mining operations also face immediate shutdowns or severe operational restrictions.
Impact on Schools
Protecting the most vulnerable is a priority. Under Stage III guidelines, education authorities are permitted to move primary classes (up to Class 5) to a hybrid learning model. This allows a mix of online and physical instruction to limit children's exposure to the poisonous air.
Understanding the GRAP Framework
The Graded Response Action Plan is a four-stage emergency system managed by the CAQM in coordination with the CPCB and state governments. The restrictions tighten as the AQI worsens:
- Stage I (Poor: 201-300): Focuses on road dust control, pollution norms, and banning open waste burning.
- Stage II (Very Poor: 301-400): Enhances dust control, increases parking fees, and introduces staggered office timings.
- Stage III (Severe: 401-450): Implements strict vehicle bans, halts construction, and introduces hybrid learning for primary schools.
- Stage IV (Severe Plus: Above 450): Involves bans on heavy goods vehicles and emergency industrial and traffic restrictions.
This proactive invocation of Stage III was based on meteorological forecasts from the India Meteorological Department (IMD) and the Indian Institute of Tropical Meteorology (IITM), ensuring that restrictions were in place before the citywide average officially breached the 401 mark.
