Implementation of GRAP-4 in Delhi-NCR
The Commission for Air Quality Management (CAQM) has activated GRAP-4 measures across Delhi-NCR following alarming air quality readings. On Saturday, Delhi recorded an Air Quality Index (AQI) of 400, indicating ‘severe’ pollution levels, which later spiked to 428 by evening. This decisive action comes a day after GRAP-III measures were enforced, reflecting the urgent need to address deteriorating air conditions.
As a result of the invoking of Stage-IV of the Graded Response Action Plan, strict regulations on vehicle operation and construction activities are now in place. The CAQM mandates that only vehicles presenting valid Pollution Under Control Certificates (PUCC) will be allowed to refuel at petrol, diesel, and CNG stations throughout the National Capital Territory (NCT) of Delhi.
Understanding GRAP and Air Quality Designations
The Graded Response Action Plan classifies air quality into four categories: ‘poor’ (AQI 201–300), ‘very poor’ (AQI 301–400), ‘severe’ (AQI 401–450), and ‘severe plus’ (AQI > 450). With current readings exceeding critical thresholds, the CAQM’s proactive measures are essential in curbing further pollution levels.
According to CAQM officials, “The measures are crucial based on the prevailing trend of air quality and relevant meteorological conditions, which have led to a marked increase in pollutants in the atmosphere,” emphasizing the need for immediate action to protect public health.
Key Restrictions and Penalties
Vehicle Regulations
Under the new regulations, all vehicles must produce a valid PUCC to refuel. Vehicles flagged through Automatic Number Plate Recognition (ANPR) systems without a valid certificate will face penalties. This will apply uniformly to all fueling stations within the NCT.
Importantly, exemptions are in place for emergency vehicles, including ambulances and police vehicles, as well as vehicles transporting essential goods or services notified by relevant authorities.
Entry Ban on Non-BS-VI Vehicles
The regulations also impose a blanket ban on motor vehicles registered outside Delhi that do not meet BS-VI emission norms. The CAQM stated that only CNG or electric-powered vehicles, public transportation modes, and essential service providers are excluded from this restriction, ensuring that vital services continue unimpeded.
This measure aims to alleviate the burden of pollution caused by older vehicles that do not comply with modern emission standards, thereby making strides towards improved air quality.
Construction Vehicle Restrictions
In addition to vehicle restrictions, vehicles that transport construction materials such as sand, concrete, and aggregates are forbidden entry into the NCT while GRAP-4 is in effect. These regulations are part of efforts to mitigate dust and emissions generated by construction activities, which significantly contribute to air pollution.
Any violations detected during this period will result in strict penalties or the seizure of the offending vehicles, emphasizing the seriousness of compliance.
Expert Opinions and Implications
Various stakeholders have expressed concern regarding the ongoing air quality crisis, pointing to the urgent need for sustained government intervention. Experts contend that frequent invocation of measures like GRAP-4 is indicative of the systemic pollution issues plaguing the region.
An environmentalist noted, “The current measures must not only be temporary fixes but part of a comprehensive strategy to improve air quality in the long run.” There is a consensus that without consistent oversight and policy enforcement, air quality will continue to decline.
Future Updates and Ongoing Monitoring
Authorities have indicated that they will maintain continuous monitoring of air quality levels. If deterioration persists, additional measures may be imposed to further restrict emissions of harmful pollutants.
As the situation develops, the CAQM will provide updates to ensure the public and stakeholders remain informed about ongoing measures and potential changes in regulations.
Conclusion
The imposition of GRAP-4 restrictions in Delhi-NCR represents a critical step towards mitigating the severe air quality crisis facing the region. With strict adherence to vehicle and construction activity regulations, officials aim to reverse the troubling trends in pollution levels and protect public health.
As the CAQM continues monitoring the situation, collaboration between government agencies, businesses, and the public will be vital for achieving a sustainable improvement in air quality.
