GRAP-3 lifted in Delhi-NCR, but curbs continue: What’s allowed, what’s not

GRAP-3 restrictions were revoked in Delhi-NCR on Thursday after a sustained improvement in air quality.

In an order, the Commission for Air Quality Management (CAQM) said Delhi’s Air Quality Index (AQI) improved to 332 on Thursday, prompting the relaxation of GRAP-3 curbs. The commission added that weather forecasts indicate the AQI is likely to remain in the ‘moderate’ to ‘poor’ category over the next few days.

GRAP-1 and GRAP-2 restrictions remain in force
While GRAP-3 restrictions have been lifted for now, Delhi-NCR will continue to remain under GRAP-1 and GRAP-2 measures.


Under GRAP-2, the use of coal and firewood is restricted, and the operation of diesel generator sets faces limitations. Additional measures include mechanical sweeping and daily water sprinkling on major roads to control dust, along with steps to ease traffic congestion in high-density areas. Authorities said these steps are aimed at preventing a fresh deterioration in air quality during the critical Diwali period.

Measures under GRAP-1 continue

The GRAP-2 restrictions build on the measures already in place under GRAP-1, which include:

A ban on labour-intensive construction activities unless strict dust-control measures, such as water sprinkling, are followed

Mandatory water sprinkling at all construction and industrial sites

Intensified inspections of industries with high pollution potential

Stricter enforcement of CNG usage for public transport vehicles to curb vehicular emissions
