The Delhi government has imposed a ban on BS-III petrol and BS-IV diesel four-wheelers as part of the Graded Response Action Plan (GRAP-III) to combat the city’s deteriorating air quality. The restriction came into effect on Friday, following the Commission for Air Quality Management (CAQM)’s directive to implement stricter measures after Delhi’s Air Quality Index (AQI) entered the “severe” category.
Key Restrictions
Under the new regulations:
- BS-III petrol and BS-IV diesel light motor vehicles (LMVs) are prohibited from plying in Delhi.
- Diesel-operated Medium Goods Vehicles (MGVs) and Light Commercial Vehicles (LCVs) registered outside Delhi are banned from entering the city unless they are carrying essential commodities or providing essential services.
- Inter-state buses from NCR states, except those running on electric, CNG, or BS-VI diesel engines, are also barred from entering Delhi, excluding vehicles with All India Tourist Permits.
Violators of these rules will face a fine of ₹20,000 under Section 194(1) of the Motor Vehicles Act, 1988.
GRAP-III Measures
The implementation of GRAP-III introduces several pollution control measures:
- Increased frequency of mechanized road sweeping and water sprinkling, especially in high-traffic areas and pollution hotspots.
- Banning demolition, earthwork, and transportation of construction and demolition waste.
- Strict dust management protocols, including the use of suppressants.
These measures aim to mitigate pollution caused by vehicular emissions and construction activities, which are significant contributors to Delhi’s worsening air quality.
Stages of GRAP
The Graded Response Action Plan is divided into four stages based on air quality:
- Stage I: ‘Poor’ (AQI 201-300)
- Stage II: ‘Very Poor’ (AQI 301-400)
- Stage III: ‘Severe’ (AQI 401-450)
- Stage IV: ‘Severe Plus’ (AQI >450)
Stage III has been implemented later this year compared to 2023 when it was invoked on November 2. The action plan supplements the Stage I and II measures already in effect across Delhi-NCR.
Rising Pollution Levels
Delhi’s air quality worsened this week, with AQI levels breaching the “severe” mark. Authorities blame emissions from vehicles, construction, and unfavorable meteorological conditions for the deterioration. Citizens are urged to cooperate with the restrictions and adhere to eco-friendly practices to minimize the impact of pollution on public health.
The Delhi government’s latest crackdown aims to address the immediate crisis while raising awareness about long-term environmental sustainability.
