GRAP-IV measures were withdrawn in Delhi-NCR on Wednesday after a noticeable improvement in air quality brought temporary relief to residents. Authorities eased the highest level of restrictions under the Graded Response Action Plan following a sharp fall in pollution levels.
Delhi’s Air Quality Index stood at 271 on Wednesday, placing it in the ‘poor’ category. A day earlier, the AQI had crossed 400 and entered the ‘severe’ range. Officials said strong surface winds and changing weather conditions helped disperse pollutants across the region.
The Commission for Air Quality Management took the decision after reviewing air quality data and near-term weather forecasts. Inputs from the India Meteorological Department and the Indian Institute of Tropical Meteorology also guided the assessment. The commission noted that pollution levels began declining from Tuesday night as meteorological conditions turned favourable.
However, authorities cautioned that the improvement may be short-lived. Forecasts indicate lower wind speeds in the coming days, which could cause pollution levels to rise again.
The Delhi government clarified that only GRAP-IV curbs have been lifted. Other pollution control measures remain in force across the capital. The ‘No PUC, No Fuel’ rule will continue without relaxation.
Environment Minister Manjinder Singh Sirsa said vehicles lacking valid Pollution Under Control certificates will not be allowed on city roads. He stressed that strict enforcement is essential to protect public health and maintain cleaner air in Delhi.
