The revamped Graded Response Action Plan -- a set of anti-air pollution measures followed in Delhi and its vicinity according to the severity of the situation -- will come into force from October 1; 15 days before the usual date, according to the Commission for Air Quality Management (CAQM).
The revised plan, which is part of a new policy formulated by the CAQM to abate air pollution in Delhi-NCR, focuses on proactive implementation of curbs based on forecasts and restrictions can be imposed up to three days in advance.
Earlier, the authorities would implement the measures only after the PM2.5 and PM10 concentration touched a particular threshold. The new plan also entails a ban on BS IV four-wheeler diesel vehicles, barring those engaged in essential services, in Delhi and the bordering districts of NCR if the air quality index (AQI) breaches the 450 mark.
