Delhi Environment Minister Gopal Rai on Wednesday said all the departments concerned have been directed to ensure strict implementation of restrictions under GRAP Stage-I and Stage-II following a weather department prediction that pollution levels in the national capital might fluctuate, reported news agency PTI.

Addressing a press conference, Gopal Rai said, "Keeping the improved pollution levels in mind, GRAP-III restrictions have been removed. However, the weather department has predicted that the pollution level could fluctuate if the wind speed slows. To avoid such a situation, all the departments concerned have been directed to ensure strict implementation of GRAP-I and GRAP-II restrictions."
