The national capital’s overall Air Quality Index (AQI) stood at 331 at 9 am, Central Pollution Control Board (CPCB) data showed.

The Commission for Air Quality Management said on Thursday that it will review the air pollution situation in Delhi on Friday.

‘Delhi-NCR AQI To Fluctuate Between Very Poor and Severe This Week’: CPCB

The CPCB directed the governments of Delhi, Haryana, UP and Rajasthan to ensure strict implementation of GRAP measures, including sprinkling water on roads.

New Delhi: The Central Pollution Control Board (CPCB) on Monday reviewed the air quality in Delhi-NCR observing that the contribution of stubble burning may rise in the next five days with the AQI fluctuating between ‘very poor’ and ‘severe’ categories.

The central pollution watchdog also observed that substantially high emissions due to the bursting of firecrackers during Diwali, local factors and stubble burning led to the decline in the air quality of Delhi to the ‘severe’ category.

Taking stock of the situation, the CPCB directed the governments of Delhi, Haryana, UP and Rajasthan to ensure strict implementation of GRAP (Graded Response Action Plan) measures including the sprinkling of water on roads.

Implementing agencies have been asked to submit daily reports to concerned state pollution control boards and committees.

During the virtual meeting of the sub-committee on Monday, its chairperson, CPCB Member Secretary Prashant Gargava, observed that due to sudden and unforeseeable change in meteorological factors, substantially high emissions on account of bursting of firecrackers and other local sources and high contribution of stubble burning, the air quality of Delhi declined to ‘severe’ but it is in ‘very poor’ category now.

The sub-committee reviewed air quality status as well as meteorological and air pollution forecasts.

“As per IMD’s forecast, winds are expected to be north-westerly for the next five days which may possibly lead to a high contribution of stubble burning, the CPCB said, adding the air quality may fluctuate between the higher end of ‘very poor’ and ‘severe’ category in the coming days.

It directed the authorities to increase the frequency of mechanised cleaning of roads and sprinkling of water on roads and ensure that all brick kilns, hot mix plants and stone crushers are closed in Delhi-NCR.

It directed the states to maximise the generation of power from existing natural gas-based plants to reduce the operation of coal-based power plants in the NCR and intensify public transport services and introduce differential rates to encourage off-peak travel.

States to disseminate information about air pollution levels and for creating awareness among citizens regarding steps to minimise air pollution.

“Implementing agencies, at appropriate level, must closely monitor actions taken and submit a daily report to concerned state pollution control boards and pollution control committees (SPCB/PCCs) which will review and further submit reports to Commission for Air Quality Management (CAQM) and CPCB, the pollution watchdog said.

In Delhi, industries which have not yet shifted to piped natural gas, will not operate during the period. On Friday, EPCA declared a public health emergency in the Delhi-NCR region and banned construction activity till November 5. It had also imposed a complete ban on the bursting of crackers during the winter season.

“According to the Meteorological Department, we are expecting better weather conditions in the next few days, including higher winds and better ventilation, which should improve air quality,” Bhure Lal said.

He reiterated the urgent need to check local sources of pollution from garbage burning to construction dust and dumping of waste. “These measures will go a long way in reducing local pollution and in helping us mitigate air pollution across the region,” he said.

Though pollution levels improved on Monday, they still remained in the “very poor” category. The air quality index on Monday afternoon read 407, a day after pollution levels peaked to a three-year high of 494. It improved further by Monday night to 370, which falls in the “very poor” category.

Increased wind speeds reduced the noxious haze that obscured Delhi’s skies for around a week.
