Delhi Air Pollution Worsens; GRAP-III Restrictions Imposed Across NCR

NEW DELHI: Air pollution in Delhi has worsened ahead of Diwali, prompting authorities to impose stricter pollution-control measures across the National Capital Region (NCR). The Commission for Air Quality Management (CAQM) on Friday, November 6, invoked Stage III of the Graded Response Action Plan (GRAP) with immediate effect as pollution levels continued to remain dangerously high.

Delhi's air quality remained in the 'Very Poor' category, with the latest hourly reading available on the cited air-quality dashboard reaching 391 at 11 am on Friday. The reading was close to the threshold of 401, at which air quality enters the 'Severe' category. However, this hourly figure should not be confused with the official daily average. The reported citywide average was 382.

Several monitoring stations across Delhi recorded pollution levels in the 'Severe' category, raising concerns about the health risks to residents, particularly children, older people and those with respiratory or heart-related conditions.

Under GRAP Stage III, non-essential construction and demolition activities have been prohibited across Delhi-NCR. The restrictions cover excavation, drilling, piling, road construction and other dust-generating operations. Stone crushers, mining activities and certain industrial units using polluting fuels have also been ordered to suspend operations.

Restrictions have also been imposed on older, highly polluting vehicles. BS-III petrol and BS-IV diesel four-wheelers are among the vehicles prohibited from operating in Delhi and specified neighbouring NCR districts. Certain diesel goods vehicles and buses are also subject to restrictions.

Schools up to Class 5 in Delhi and specified NCR districts have been directed to conduct classes in hybrid mode, allowing students to attend online or in person. Private offices have been advised to consider work-from-home or hybrid arrangements to reduce traffic and vehicle emissions.

The authorities have also intensified measures to control road dust and industrial pollution. Diesel generator use has been restricted, except for emergency and essential services.

The latest restrictions come just days before Diwali, when increased traffic and firecracker emissions could further worsen air quality. Residents have been advised to limit prolonged outdoor activities, particularly during periods of heavy pollution, and take necessary precautions.

With pollution levels approaching the severe category, authorities are closely monitoring the situation to prevent further deterioration across the national capital and surrounding regions.
