GRAP-IV measures withdrawn in Delhi-NCR after air quality shows improvement
PTC Web Desk: After a brief spell of extreme pollution, air quality in Delhi-NCR showed relief on Wednesday, prompting the authorities to remove the highest level of restrictions under the Graded Response Action Plan (GRAP-IV).
Delhi’s Air Quality Index (AQI) improved to 271 on Wednesday, placing it in the ‘poor’ category. This marked a sharp recovery from the previous day, when pollution levels had crossed 400 and entered the ‘severe’ range. Officials said strong winds and changing weather conditions helped reduce pollution levels across the region.
The Commission for Air Quality Management (CAQM) said the decision to ease restrictions was taken after a detailed review of air quality data and weather forecasts. Inputs from the India Meteorological Department (IMD) and the Indian Institute of Tropical Meteorology (IITM) were also considered during the assessment.
According to the commission, pollution levels started falling from Tuesday night as meteorological conditions turned favourable. However, it warned that the improvement may not last long, as lower wind speeds in the coming days could lead to a rise in pollution again.
The Delhi government clarified that while GRAP-IV measures have been withdrawn, other pollution control steps remain unchanged. The ‘No PUC, No Fuel’ rule will continue to be enforced strictly.
Environment Minister Manjinder Singh Sirsa said vehicles without a valid Pollution Under Control (PUC) certificate will not be allowed to operate in the city. He stressed that ignoring emission norms directly harms Delhi’s air quality and public health.
