As Delhi’s Air Quality Index (AQI) surged to a hazardous 424, the Central Pollution Control Board (CPCB) reported a concerning rise in pollution levels, compelling authorities to step up emergency measures. With the daily AQI hovering around 425, heavy fog and unfavorable weather conditions across the Indo-Gangetic Plain have further intensified the challenges related to air quality. In response, Delhi's Graded Response Action Plan (GRAP) Sub-Committee has implemented Stage-III restrictions, targeting the 'Severe' AQI category, starting at 8:00 AM on November 15, 2024.
Stage-III measures represent a critical escalation, aiming to mitigate pollution in Delhi and the surrounding National Capital Region (NCR). This phase of the GRAP introduces an 11-point action plan, mandating stricter pollution control for construction, transport, and industrial activities. Notably, construction and demolition (C&D) activities that generate dust, such as excavation and major welding, are now banned. Only essential projects, such as hospitals, national security facilities, and transportation infrastructure, may continue, provided they comply with strict dust prevention rules.
Transport restrictions are equally strict under Stage-III. BS-III and BS-IV diesel vehicles will face restrictions in Delhi and key NCR districts, limiting their operations to essential services. Additionally, inter-state buses powered by diesel below BS-VI standards are now barred from entering Delhi unless they run on electric or CNG power. Public transport services are also set to increase to minimize private vehicle use, encouraging citizens to rely on cleaner travel options.
The Sub-Committee has issued a directive for enhanced street-cleaning measures. Roads will be swept and sprayed with water to prevent dust accumulation, especially in high-traffic areas. The goal is to reduce particulate matter, which remains a primary pollutant during the winter months.
Beyond these government efforts, the Commission for Air Quality Management (CAQM) has urged residents to play a role in curbing pollution. Citizens are encouraged to walk or bike for short trips, avoid burning coal or wood for heat, and consider carpooling to reduce emissions. Residents who can work from home are advised to do so, and even school attendance may shift online for younger students if conditions worsen.
With Delhi’s pollution levels fluctuating in the ‘Very Poor’ and ‘Severe’ categories, the GRAP aims to bring some relief.
