Delhi Fights Smog: GRAP Stage 1 Implemented as Air Quality Dips
Delhi Police announce GRAP Stage 1 implementation to fight rising air pollution. Check new traffic rules and AQI levels here.

As the national capital begins its annual struggle with deteriorating air quality, the authorities have officially triggered the first stage of the GRAP stage 1 Delhi (Graded Response Action Plan). This emergency measure comes after a sharp spike in pollution levels, pushing the city's air into the "poor" category and prompting immediate intervention from the Commission for Air Quality Management (CAQM).
Traffic Crackdown to Curb Emissions
The Delhi Police have stepped up their efforts to ensure that vehicle emissions do not further choke the city. Vijayanta Goyal Arya, Additional Commissioner of Police (Traffic), informed reporters that the Traffic Police are making strategic deployments to reduce congestion and manage the flow of vehicles more efficiently.
Key measures being implemented include:
- Border Diversions: Commercial vehicles that are not destined for the city will be diverted at the borders to prevent unnecessary traffic influx.
- PUCC Enforcement: Authorities are intensifying checks for valid Pollution Under Control Certificates (PUCC). Drivers are strongly advised to ensure their certificates are up to date to avoid penalties.
- Strict Action: A crackdown on vehicles with expired pollution certificates is already underway and will be scaled up in the coming days.
"The first stage of the Graded Response Action Plan (GRAP) has been implemented in Delhi. Accordingly, Delhi Traffic Police will make appropriate deployments to minimise congestion. We appeal to the public to keep their Pollution Under Control Certificates (PUCCs) valid," stated ACP Vijayanta Goyal Arya.
The Numbers: A City Gasping for Air
The decision to invoke GRAP Stage 1 was driven by alarming data from the Central Pollution Control Board (CPCB). By 7 am on Thursday, the overall Air Quality Index (AQI) for the city stood at 226, falling squarely into the "poor" category.
Hotspots of Pollution
While the city average was poor, several areas recorded even more dangerous levels:
- Very Poor Category: Jahangirpuri (309) and Chandni Chowk (307).
- Poor Category: Patparganj (298), Rohini (291), Alipur (273), Bawana (275), ITO (280), Wazirpur (253), Anand Vihar (237), Akshardham (237), and Ashok Vihar (223).
For context, the CPCB categorizes AQI between 201 and 300 as "poor," while 301 to 400 is deemed "very poor," and anything above 401 is "severe."
Why Now? The Sudden Spike
The trigger for this action was a rapid deterioration in air quality over a very short window. On October 20, the AQI was recorded at 179, which fell under the "moderate" category. However, by 2:00 PM on October 21, the index jumped to 244. Forecasts from the IMD and IITM suggest that the air quality is likely to remain in the "poor" category for several days, necessitating the immediate rollout of the action plan.
A Call for Public Cooperation
The Delhi Police have urged citizens to play an active role in improving the environment. The public is being encouraged to shift toward public transport as much as possible and strictly adhere to traffic regulations to minimize the overall environmental impact and reduce the daily inconvenience caused by traffic congestion.
