GRAP Stage 3 Revoked in Delhi-NCR as Air Quality Improves

Authorities in Delhi-NCR have lifted stringent Stage 3 restrictions under the Graded Response Action Plan (GRAP) following a noticeable improvement in air quality. The decision brings relief to motorists and construction sectors, though several lower-stage measures remain in force to prevent further deterioration.

Improved Air Quality Triggers Policy Change

The Commission for Air Quality Management revoked Stage 3 measures after Delhi’s 24-hour average AQI settled at 327, placing it in the ‘Very Poor’ category. While still unhealthy, this level is below the ‘Severe’ threshold of 401–450 that mandates Stage 3 restrictions. The winter-specific GRAP framework categorises pollution response into four stages, from ‘Poor’ to ‘Severe Plus’, triggering different levels of intervention.

Ban on BS-III Petrol and BS-IV Diesel Vehicles Lifted

One of the most significant relaxations is the removal of the ban on BS-III petrol and BS-IV diesel vehicles. These vehicles may now ply across Delhi-NCR. However, authorities stressed that Stage 1 and Stage 2 measures continue to apply. These include actions against polluting vehicles, bans on open burning, improved waste management, and enhanced road cleaning.

Measures Still Active Under Stage 1 and Stage 2

Stage 1 rules require strict dust control at construction sites, mechanical road sweeping, continuous water sprinkling, and reduced reliance on diesel generators. With AQI still in the ‘Very Poor’ range, Stage 2 adds higher penalties for non-compliant projects, increased parking fees, and tighter oversight to limit private vehicle usage. Agencies also aim to ensure uninterrupted electricity to avoid generator emissions.

Exam Oriented Facts

• GRAP Stage 3 restrictions in Delhi-NCR have been revoked.
• Delhi’s AQI stood at 327 in the ‘Very Poor’ category.
• Ban on BS-III petrol and BS-IV diesel vehicles has been lifted.
• Stage 1 and Stage 2 measures remain in force across the region.

Public Advisory and Ongoing Precautions

Authorities continue to advise residents to reduce private vehicle use and shift towards public transport. Enforcement teams remain active at construction sites and along major corridors to monitor dust, waste and vehicle emissions. With pollution levels still elevated, strict adherence to Stage 1 and 2 protocols is expected to guide Delhi-NCR’s air quality management in the coming days.
