With air high quality worsening once more, stricter air pollution curbs underneath GRAP 3 had been reimposed in Delhi and surrounding areas, the Fee for Air High quality Administration (CQAM), the Centre’s air pollution watchdog, stated on Friday.
The Graded Response Motion Plan (GRAP) is a set of emergency measures carried out in Delhi-NCR to sort out air air pollution based mostly on the severity of the Air High quality Index (AQI).
The Supreme Courtroom had earlier directed that GRAP’s Stage III measures should be carried out if the AQI exceeds 350 and Stage IV measures reintroduced if it surpasses 400. Stage III and Stage IV had been activated on December 16 after AQI ranges hit 401.
“The Sub-Committee noticed that the AQI of Delhi is exhibiting an growing pattern, crossed 350 within the morning right now and has been recorded 371 at 4:OO PM owing to dense fog, low mixing top, variable winds and unfavourable meteorological situations,” stated the Centre’s air pollution watchdog.
The forecast from the climate workplace suggests a “probability of the AQI of Delhi to significantly stay on this adversarial vary for the approaching days”, stated the watchdog.
The GRAP for Delhi-NCR is split into 4 phases of air high quality — Stage 1 for “poor” Air High quality Index (AQI) ranging between 201 and 300, Stage 2 for “very poor” AQI of 301-400, Stage 3 for “extreme” AQI of 401-450 and Stage 4 for “extreme plus” AQI (greater than 450).
