Delhi Air Quality Improves Post Rainfall, GRAP Stage 4 Restrictions Revoked

NEW DELHI: The fog situation seems to have improved in Delhi and its adjoining cities, with the air quality getting better after rainfall on Wednesday that helped drop the AQI, prompting authorities to revoke the GRAP 4 restrictions.

The Commission for Air Quality Management (CAQM) on Thursday revoked Stage IV measures of the Graded Response Action Plan (GRAP) for Delhi and the National Capital Region (NCR) following a notable improvement in air quality.

The India Meteorological Department (IMD) has predicted partly cloudy skies for Friday with smog and dense fog likely in most areas during the morning and very dense fog in isolated pockets. Shallow fog or smog may persist in the evening and night, IMD said.

Delhi airport said in an advisory at 07:50 am that flights that are not CAT III compliant may get affected, asking passengers to check with the airline concerned to stay updated about the timings. CAT III facility allows aircraft to operate in low-visibility conditions.

A day after announcing GRAP 4 curbs, the Centre's panel on Delhi-NCR's air quality on Thursday revoked the restrictions amid a dip in pollution levels. Stage 4 curbs include a ban on all construction activities, entry of non-essential polluting trucks into Delhi, and mandatory shifting of school classes, except for classes 10 and 12, to hybrid mode.
