Winter Is Coming: Anti-Pollution Curbs Imposed In Delhi For 1st Time This Season

Signalling the annual return of the dreaded pollution in the capital, the Commission for Air Quality Management, which is the Centre's anti-pollution panel, has enforced curbs under GRAP-1 in Delhi and the National Capital Region (NCR).

The CAQM announced the decision on Tuesday, when Delhi's Air Quality Index was recorded at 211, which is in the 'Poor' category. 

The Sub-Committee on GRAP, in a review meeting, analysed real-time data from the Central Pollution Control Board (CPCB) alongside forecasts from the India Meteorological Department (IMD) and the Indian Institute of Tropical Meteorology (IITM).

"The AQI has entered the 'Poor' threshold, and projections indicate sustained levels in this range over the coming days due to stagnant weather conditions," the committee noted in its order. This marks the first formal activation of GRAP measures for the season.

Under Stage-I ('Poor' Air Quality, AQI 201-300), a slew of enforcement actions will have to be taken by district administrations, pollution control boards and municipal bodies in Delhi as well as NCR districts in Uttar Pradesh, Haryana, Rajasthan, and Punjab.

The key measures include:

• Construction Dust Control: Strict ban on labour-intensive construction activities without dust mitigation; mandatory water sprinkling at all project sites.
• Industrial and Vehicular Curbs: Heightened inspections of polluting industries and enhanced CNG compliance for public transport.
• Waste Management: Putting an immediate stop to all garbage-burning activities, and intensifying bio-medical waste handling protocols.
• Road and Power Sector: Black carbon emission audits for heavy vehicles; power plants within 10 km of Delhi to switch to 100% piped natural gas.

The order emphasises rigorous monitoring, with all agencies directed to "intensify measures" and maintain "strict vigil" to prevent the AQI from slipping into 'Very Poor' or 'Severe' categories. Citizens are also urged to follow the GRAP Stage-I Citizen Charter, which includes voluntary steps like using public transport, avoiding outdoor exertion during peak pollution hours (evenings), and reporting violations via CAQM's helpline (1800-180-1708).

Environmental experts welcomed the intervention but cautioned that deeper structural reforms are needed. "GRAP is a band-aid; without tackling stubble burning and interstate coordination head-on, we are just postponing the inevitable smog blanket," said Dr Anumita Roychowdhury, Executive Director of the Centre for Science and Environment (CSE). 

Data from IITM's high-resolution forecasting system, which boasts over 80% accuracy in predicting 'Very Poor' episodes, underscores this: Calm winds and clear skies forecast for the next week could trap pollutants, potentially elevating the AQI to 250+ by the end of the month. Also, while September has been relatively clean this year, historical trends show Delhi's AQI plummets after Diwali. 

Last winter, the region endured over 50  'Severe' days, costing billions in health and economic losses.
