Delhi and its surrounding areas have been shrouded in dense smog, with the air quality index (AQI) crossing 400, placing it in the ‘Severe’ category. The Commission for Air Quality Management (CAQM) deemed the thick morning smog an “episodic event” but has nonetheless activated stage III of the Graded Response Action Plan (GRAP-3) starting from 8 am Friday.
What is GRAP Stage III?
GRAP-3 is the third phase of the anti-pollution plan, enacted when AQI reaches 401-450. Here’s a breakdown of restrictions:
Construction and Demolition Ban: Non-essential construction and demolition activities are banned, with exceptions for critical infrastructure, national security, and healthcare projects.
Vehicle Restrictions: BS-III petrol and BS-IV diesel vehicles are prohibited on Delhi and NCR roads, including Gurugram, Faridabad, Ghaziabad, and Noida.
