​Gurugram: Met factors help, air better, but still in ‘very poor’ zone


GURUGRAM: With pollution climbing down a band – from ‘severe’ until two days ago to ‘very poor’ – the Commission of Air Quality Management (CAQM) scaled down restrictions by a notch on Sunday, revoking its ban on diesel vehicles that didn’t meet BS-VI emission standards in NCR.


Gurugram’s average air quality for the past 24 hours improved to 308 on Sunday, down from 357 the day before, owing to a change in wind direction that washed away some of the pollutants.

But the AQI is still in the ‘very poor’ (300-400) category. The CAQM’s Sunday order withdrew stage four of the Graded Response Action Plan (GRAP-4), but clarified that restrictions under the previous stages of GRAP until the third phase would remain in effect in the National Capital Region.
It means the bans on entry of commercial trucks into Delhi, diesel vehicles that don’t comply with BS-VI standards, and construction and demolition (C&D) activities in essential projects such as highways and railways have been lifted.
But “actions under Stages-I to Stage-III of the GRAP shall however remain invoked and be implemented, monitored and reviewed by all agencies concerned in the entire NCR to ensure that the AQI levels do not slip further to the ‘Severe’/ ‘Severe +’ category”, the commission said in its order.
This means the ban on construction in the private sector and all projects not deemed essential will continue. Under GRAP-3, activities such as excavation work, ferrying of construction materials and repair work on roads are also banned. Authorities have to carry out mechanised sweeping of roads, sprinkle water and ensure proper disposal of dust as well. Of the four air quality monitoring stations in Gurugram , three recorded Sunday’s average AQI in as ‘very poor’: 308 at Sector-51, 315 at Teri Gram and 325 at Gwalpahari. The AQI in Vikas Sadan was 275.
Haryana State Pollution Control Board (HSPCB) officials said they expect this partial relief from severely toxic air to continue over the next few days. Rains are also predicted over the two days.
“Yes, the AQI improved on Sunday due to a western disturbance in the region and change in wind direction to the easterly.There is also a prediction of rain on Tuesday and Wednesday, and that’s why the air quality will stay in a lower level of ‘very poor’ for a few days now,” said Sandeep Singh, regional officer, HSPCB, Gurugram .
But this window of ‘very poor’ air days is not expected to last long. By next week, the AQI could touch ‘severe’ levels for a second spell this month.
“The region will witness a dip in AQI around November 12 due to dip in temperature, calmer winds and stubble burning,” an IMD official said. According to SAFAR, farm fires are currently contributing 18% to PM2.5 emissions in Delhi.
