Delhi-NCR AQI Slips Into ‘Poor’ Category; GRAP Stage 1 Enforced - What’s Allowed And What’s Not

The Commission for Air Quality Management (CAQM) has activated Stage 1 of the Graded Response Action Plan (GRAP) across Delhi and nearby regions after the air quality worsened to the "poor" category.

The move comes as Delhi's Air Quality Index (AQI) showed a rising trend due to unfavourable weather conditions.

AQI Reaches 'Poor' Category

According to officials, Delhi's AQI was recorded at 226, which falls under the "poor" category. This indicates that air pollution levels have increased and may start affecting sensitive groups such as children, elderly people, and those with respiratory issues.

The India Meteorological Department (IMD) has also predicted that the air quality is likely to remain in the "poor" category for the next two days.

Why Pollution Levels Are Rising

Authorities have linked the worsening air quality to changing weather conditions. Factors such as low wind speed, temperature changes, and stagnant air are preventing pollutants from dispersing.

As a result, pollution is accumulating in the atmosphere, leading to a steady increase in AQI levels.

What Is GRAP Stage 1?

The Graded Response Action Plan (GRAP) is a set of emergency measures implemented in Delhi-NCR to control air pollution based on AQI levels.

Stage 1 is activated when the air quality reaches the "poor" category and includes preventive actions to stop further deterioration.

Key Restrictions and Measures

Under GRAP Stage 1, several rules have been enforced to control pollution:

Dust Control Measures

• Anti-smog guns will be used at construction and demolition sites
• All projects above 500 square metres must follow strict dust control rules

Ban on Open Burning

• Burning of garbage, leaves, and other waste is strictly prohibited

Restrictions on Fuel Use

• Coal and wood are banned in roadside eateries and commercial kitchens
• Restaurants must use cleaner fuels like gas or electricity

Limits on Diesel Generators

Diesel generators can only be used in emergency or essential situations

Action Against Polluting Vehicles

• Vehicles causing pollution may face fines or be impounded
• Traffic police will monitor key areas to reduce congestion

Rules for Old Vehicles

Diesel vehicles older than 10 years and petrol vehicles older than 15 years are not allowed on roads

Traffic and Public Advisory

Authorities have also advised drivers to switch off engines at traffic signals to reduce emissions. Traffic police will be deployed at busy junctions to manage congestion and limit pollution caused by idling vehicles.
