Delhi Pollution Crisis: Ban on BS-III Petrol and BS-IV Diesel Vehicles Enforced to Combat 'Severe' AQI

Delhi Pollution Crisis

Delhi’s battle against air pollution has taken a decisive turn with the government imposing a ban on BS-III petrol and BS-IV diesel four-wheelers under the Graded Response Action Plan (GRAP-III). The move, effective from Friday, is aimed at curbing the alarming rise in Air Quality Index (AQI), which has slipped into the ‘severe’ category. Violators will face a ₹20,000 fine under Section 194(1) of the Motor Vehicle Act, 1988.

Key Restrictions in Place

• Vehicle Ban: BS-III petrol and BS-IV diesel vehicles, including Delhi-registered medium goods vehicles (MGVs) running on diesel, are prohibited from plying in the city. Exceptions are made only for vehicles transporting essential commodities or providing critical services.
• Interstate Vehicles: Non-CNG, non-EV, and non-BS-VI interstate buses from NCR regions are barred from entering Delhi unless equipped with an All India Tourist Permit.

This stringent enforcement follows directives from the Commission for Air Quality Management (CAQM), which activated GRAP-III measures on Friday at 8 am.

A Multi-Faceted Action Plan

To mitigate the worsening pollution levels, several complementary measures have been implemented under GRAP-III:

Enhanced Road Maintenance: Increased frequency of mechanized sweeping and daily water sprinkling on roads, particularly in high-traffic areas.

Dust Control: Banning all demolition activities, earthwork, and the transportation of construction and demolition waste.

Waste Disposal: Ensuring proper disposal of collected dust at designated landfills to prevent further pollution.

Public Transport Push: Encouraging the use of public transport to reduce vehicular emissions.

Rising Pollution Levels in Context

The AQI in Delhi is classified under four categories:

• Poor (201-300)
• Very Poor (301-400)
• Severe (401-450)
• Severe Plus (450+)

This year, the city has managed to delay reaching the ‘severe’ AQI levels, which had worsened as early as November 2 in 2023. However, the worsening conditions now necessitate an 11-point action plan, including intensified road cleaning and public awareness campaigns.

A Crisis in Perspective

Delhi’s air pollution is not a new concern. Each winter, the city grapples with toxic smog, worsened by vehicular emissions, construction dust, and seasonal stubble burning. This year’s measures are part of the government’s broader clean air initiatives, which aim to provide long-term relief for residents.

While these steps are crucial, their success will depend on strict enforcement, public cooperation, and sustained efforts to tackle the root causes of pollution.

Delhi residents must brace for tighter restrictions, but these measures are a necessary step toward a cleaner, healthier future.
