Amid worsening air quality and a sudden surge in pollution levels, the Commission for Air Quality Management (CAQM) has implemented Stage-I of the Graded Response Action Plan (GRAP) across Delhi and the National Capital Region (NCR). The move comes after a sharp dip in the Air Quality Index (AQI) over the past few days, driven primarily by strong winds carrying dust from distant regions. Authorities have urged residents to limit outdoor activities, prefer public transport, and follow pollution control norms strictly as precautionary steps take center stage to tackle the crisis.
Why Stage-I GRAP Was Enforced
On May 15, the air quality in Delhi deteriorated significantly, and by May 16, the AQI touched 278 — categorised as ‘Poor’. This prompted the CAQM’s sub-committee to convene an emergency meeting, where they assessed air quality trends and weather projections. Forecasts from the India Meteorological Department (IMD) and the Indian Institute of Tropical Meteorology (IITM) indicated that the air quality would likely remain in the lower spectrum of the ‘Poor’ category through May 17. Dust storms triggered by strong winds from far-off areas were cited as the main contributors to this pollution event, which experts believe is short-lived but still poses serious health risks.
In response, Stage-I restrictions under GRAP were swiftly rolled out. These initial measures are designed to contain pollution at its source, targeting dust, vehicular emissions, and industrial pollutants. Notably, dust control measures have been mandated at all construction and demolition sites larger than 500 square metres, with projects required to have an approved dust management plan in place.
Key Restrictions Now in Force
To reduce emissions, the use of coal and firewood in roadside food stalls and commercial kitchens has been banned. Cooking in hotels, restaurants, and open eateries must rely on clean energy sources like electricity or gas. The operation of diesel generators is also limited to emergency or essential purposes only.
Authorities have intensified monitoring at traffic intersections, urging drivers to switch off engines at red lights. Older diesel vehicles (over 10 years) and petrol vehicles (over 15 years) remain prohibited in Delhi. The sale, storage, and use of firecrackers are completely banned across NCR until January 1, 2025.
Polluting industries and thermal power plants within a 300 km radius of Delhi may face enforcement action. The CAQM is keeping a close watch on pollution trends and may escalate measures to Stage-II if conditions worsen. Meanwhile, residents can report violations via the Green Delhi App, SAMEER App, or by calling 311.
Stage-I measures apply uniformly across the region, including key transit points like Indira Gandhi International Airport, Hindon Airport, and Safdarjung Airport, ensuring a coordinated approach in managing air quality throughout Delhi-NCR
