Air Quality in Delhi Plummets, GRAP-3 Restrictions Imposed After AQI Crosses 300

In light of escalating air pollution levels in Delhi-NCR, driven by adverse meteorological conditions, the Central government's air quality panel has reinstated Stage 3 restrictions of the Graded Response Action Plan (GRAP). This move, detailed in an official announcement, aims to tackle the deteriorating air quality, which saw the 24-hour average air quality index (AQI) reaching 371 at 4 pm. The Commission for Air Quality Management, tasked with outlining strategies to curb air pollution in the area, has mandated the immediate enforcement of these restrictions to mitigate further degradation of air conditions.

Forecasts from the India Meteorological Department and the Indian Institute of Tropical Meteorology have predicted a further decline in air quality due to unfavorable weather patterns. Last lifted just a week ago, GRAP Stage 3 includes measures such as prohibiting non-essential construction activities. This reinstatement underscores the ongoing struggle against pollution in the region, emphasizing the need for stringent actions to combat the environmental crisis.

Delhi has been engulfed in a thick fog, significantly reducing visibility across the city, including major areas like the Delhi Airport. This weather phenomenon also extended to neighboring states like Punjab and Haryana, where dense fog has persisted, keeping the minimum temperatures around normal levels. The Met Department highlighted that this dense fog coverage has been consistent over the past few days, impacting visibility and leading to cooler temperatures. For instance, Chandigarh experienced a heavy fog cover with the mercury dropping to 10.4 degrees Celsius, a figure three degrees above normal for this time of year.

Under the GRAP-3 directives, several restrictions are in place to curb pollution levels. These include a ban on older, more polluting vehicles, specifically BS-III petrol and BS-IV diesel cars, within Delhi and its adjoining NCR districts. Additionally, diesel-powered medium goods vehicles that do not meet the BS-IV emission standards are prohibited from operating. Another significant measure is the suspension of non-essential construction work to reduce dust and emissions contributing to the air quality deterioration.

In response to the reinstated Stage 3 restrictions, educational adjustments have been made to safeguard the health of young students. Schools up to grade V are now required to operate in a hybrid mode, offering parents and students the flexibility to opt for online classes where feasible. This decision reflects the authorities' commitment to ensuring the safety and well-being of residents amidst the ongoing pollution crisis.

As Delhi-NCR grapples with the challenge of 'very poor' air quality, with the AQI soaring above 300, the reimplementation of GRAP-3 restrictions underscores the urgency of addressing environmental concerns. This initiative aims at making a significant impact on the air quality, ensuring the health and safety of the region's inhabitants. The measures taken, from banning certain vehicles to halting non-essential construction, are steps towards mitigating pollution levels and fostering a cleaner, healthier environment for all.
