AQI Back to Very Poor: Delhi Makes GRAP-4 Curbs Permanent, Check What Is Banned
The phrase AQI back to very poor has again returned to headlines as Delhi’s air quality sharply deteriorates. In response, the Delhi government has decided to make two key restrictions under GRAP-4 permanent. The move reflects growing concern over recurring winter pollution and its impact on public health.
Delhi Environment Minister Manjinder Singh Sirsa announced the decision on Saturday. He said fuel stations across the city will now deny petrol to vehicles without a valid Pollution Under Control Certificate (PUCC). Earlier, authorities applied this rule only during severe pollution phases. However, the government will now enforce it until further notice.
Moreover, the government has restricted the entry of non-BS6 vehicles from outside Delhi. Officials believe these steps will reduce emissions at the source. The decision comes as weather conditions threaten to worsen pollution levels further.

‘No PUCC, No Fuel’ Rule Made Permanent
Under the first permanent restriction, petrol pumps across Delhi will follow the ‘No PUCC, No Fuel’ rule. Vehicles without a valid pollution certificate will not receive fuel. Authorities have directed fuel station operators to strictly comply.
Minister Sirsa clarified the government’s stance while addressing reporters. He said this rule will remain in force without any relaxation. According to officials, many vehicles continue to operate without updated pollution checks.
Moreover, officials argue that regular PUCC enforcement can significantly reduce vehicular emissions. Transport department teams have already intensified inspections across major fuel stations. Violators may face fines and legal action.
Environmental experts welcomed the move. They said consistent enforcement works better than temporary bans. However, they also stressed the need for public awareness.
BS6 Norms Mandatory for Vehicles Entering Delhi
The second permanent restriction targets vehicles entering Delhi from outside states. According to the government, only Bharat Stage VI (BS6) compliant vehicles will be allowed entry. Older vehicles with higher emissions will face restrictions.
Sirsa said inter-state vehicular pollution contributes heavily during winter months. Therefore, authorities decided to tighten checks at Delhi’s borders. Enforcement teams will monitor compliance at entry points.
Additionally, officials may use automatic number plate recognition systems for monitoring. This step aims to reduce emissions from commercial and private vehicles alike.
Transport experts say BS6 vehicles emit significantly fewer pollutants. As a result, this move could offer long-term benefits. However, it may also inconvenience commuters using older vehicles.
Weather Conditions Under Close Watch
The government’s decision comes amid warnings of adverse weather conditions. According to officials, a Western Disturbance may affect the region soon. Such conditions can trap pollutants closer to the ground.
Sirsa said the government is closely monitoring meteorological updates. He added that preventive steps are necessary before pollution spikes further. Moreover, authorities want to avoid emergency measures later.
Weather experts say low wind speed and fog worsen air quality. Therefore, proactive enforcement becomes crucial during this period.
AQI Back to Very Poor Across Delhi
Delhi’s air quality already reflects these concerns. Data from the Central Pollution Control Board (CPCB) showed an AQI of 390 at 6 pm on December 27. This level places the city in the ‘Very Poor’ category.
Such pollution levels pose serious health risks. Children, elderly people, and patients with respiratory issues remain most vulnerable. Doctors advise limiting outdoor exposure during peak pollution hours.
Meanwhile, thick smog and dense fog have reduced visibility in several areas. Traffic movement has slowed, and daily routines face disruption. Authorities have urged residents to follow health advisories.
Stage III GRAP Measures Also Invoked
Alongside permanent GRAP-4 curbs, authorities have invoked Stage III measures under GRAP. The Commission for Air Quality Management (CAQM) announced restrictions on construction activities.
Certain industrial operations that generate dust and emissions now face limits. Officials said enforcement teams are ensuring compliance on the ground.
Moreover, agencies continue road sprinkling and mechanized sweeping. These steps aim to control particulate matter levels.
Long-Term Pollution Control Push
The latest measures form part of a broader environmental strategy. Earlier, the Delhi Cabinet approved ₹100 crore for rejuvenating water bodies across the city. Around 160 water bodies fall under the Delhi government’s control.
Officials say cleaner water bodies can help improve local microclimates. Additionally, green initiatives support long-term resilience against pollution.
Sirsa emphasized that the government wants permanent relief, not short-term fixes. He said residents should not face repeated pollution-related hardships every winter.
As AQI back to very poor remains a reality, authorities urge citizens to cooperate. Experts say lasting improvement requires both policy enforcement and public responsibility.
