AQI below 200, Grap measures yet to kick in

Measures under the revised Graded Response Action Plan (Grap), which are implemented every year in phases from October 1, did not come into effect in the National Capital Region (NCR) on Sunday, as Delhi's air quality index (AQI) improved to 143 - below the threshold of 201 for the anti-pollution measures to kick in.

The plan can come into effect whenever Delhi's AQI crosses 200.

However, forecasts by the Early Warning System show that the city's AQI is likely to remain below 200 till at least October 10, meaning stage 1, or the "poor" air category measures, are not likely to come into force immediately, officials said.

Stage 1 of Grap has 27 measures, including shutting down of some construction and demolition sites, encouraging offices to start unified commute for employees, mechanised sweeping and water sprinkling on roads, and deployment of traffic police at points with heavy traffic.
