The sub-committee of CAQM invoked the measures after the Air Quality Index (AQI) in Delhi surged from 362 on Monday to 425 on Tuesday morning, citing calm winds, a stable atmosphere, and unfavourable meteorological conditions as key factors behind the sudden spike
Under Stage-3 of GRAP, several additional restrictions come into force, including a ban on construction and demolition activities, except for essential projects such as roads, railways, and airports
Industries using unapproved fuels are also required to halt operations, while agencies are mandated to intensify mechanical road cleaning and dust suppression through water sprinkling
The CAQM noted that the decision aims to "prevent further deterioration of air quality in the region" and is in addition to measures already in effect under Stages-1 and 2
The GRAP Stage-3 corresponds to the 'severe' category, applicable when the AQI ranges between 401 and 450.
