Delhi’s air quality deteriorated to the ‘very poor’ category for the first time this winter on Monday, November 2, prompting the Commission for Air Quality Management (CAQM) to invoke Stage 2 of the Graded Response Action Plan (GRAP) across the National Capital Region (NCR). The city’s Air Quality Index (AQI) reached 324 at 4 pm, up from 261 on Sunday. The sharp deterioration followed a reading of 117 on October 31, when Delhi’s air quality was in the ‘moderate’ category. The AQI of 324 was the highest recorded since February 11, according to the report.  The Central government’s Air Quality Early Warning System for Delhi forecast that pollution levels would remain in the ‘very poor’ category for the next three days. CAQM cited unfavourable meteorological conditions and forecasts from the India Meteorological Department and the Indian Institute of Tropical Meteorology while announcing the restrictions.  Stage 2 GRAP measures include intensified mechanical and vacuum road sweeping, water sprinkling with dust suppressants, and stricter inspections at construction and demolition sites. Authorities have also been directed to increase vehicle parking fees to discourage private transport. Delhi and NCR state governments have been advised to introduce staggered timings for public offices and municipal bodies. The Delhi Metro Rail Corporation will operate 20 additional trips on weekdays to encourage commuters to use public transport. Residents have been urged to minimise private vehicle use, avoid open burning of waste and follow pollution-control guidelines as authorities monitor the situation.
