IMPORTANT Directions under section 5 of the Environment (Protection) Act, 1986, to all Government Offices under GNCTD and all Private Offices operating within the National Capital Territory of Delhi, to work on 50% strength and the rest to work from home under Graded Response Action Plan. The AQI of Delhi which was recorded as 431 today at 4 PM exhibited an increasing trend and has been recorded 441 at 6 PM on date owing to slow wind speed, stable atmosphere, unfavourable weather parameters and meteorological conditions and lack of dispersal of pollutants. Keeping in view the prevailing trend of air quality and in an effort to prevent further deterioration of air quality in the region, the CAQM Sub-Committee on GRAP decides to invoke all actions as envisaged under Stage-IV of the extant GRAP – ‘Severe ’ Air Quality (DELHI AQI > 450), with immediate effect, in the entire NCR. This is in addition to the actions under Stages I, II & III of extant GRAP already in-force in NCR. Further, NCR Pollution Control Boards/ Committee and other agencies concerned have been asked to escalate the preventive measures to prevent further deterioration of air quality in the region.
