Cleanest air since Sept 29, Delhi out of GRAP’s grasp
The air quality in the capital recorded a satisfactory range reading of 85 on Saturday due to strong winds and rain and prompted the Commission for Air Quality Management (CAQM) to revoke measures enforced under stage I of the Graded Response Action Plan (GRAP). The CAQM had imposed the GRAP restrictions on March 7 after the AQI reached 202. Delhiites on Saturday inhaled the cleanest air since Sept 29 last year when the AQI was 76. "The AQI has shown significant improvement due to favourable winds, light rain/drizzling and improved meteorological conditions in Delhi-NCR. Forecasts by IMD/IITM indicate that the average air quality of Delhi to stay in the ‘satisfactory' to ‘moderate' category in the coming days. It was unanimously decided to revoke Stage-I of the extant schedule of GRAP in the entire NCR, with immediate effect," said CAQM in a statement. CAQM wrote on X that Delhi recorded an average AQI of 85, the lowest in the last three years for the period from Jan 1 to March 15. The commission directed all the agencies to take note of various actions and the targeted timelines issued by CAQM to curb air pollution in NCR and take appropriate actions accordingly in the field, "particularly the dust mitigation measures for C&D activities and roads or open areas, which would become a predominant factor in the coming months determining the air quality in Delhi-NCR." The measures under Stage I are preventive in nature, directing govt agencies to intensify measures to control air pollution. This includes intensifying the use of anti-smog guns, water sprinkling and dust suppression measures in road construction, widening or repair projects and maintenance activities, and strict vigilance and enforcement of PUC norms for vehicles. Anumita Roychowdhury, executive director of research and advocacy at the Centre for Science and Environment, said: "Air quality will be highly variable now as we are transitioning from winter to summer and meteorological conditions will keep changing. But we need to see a firm downward trend in pollution levels...." The city recorded the highest maximum temperature of the year on Friday on Holi.
