The move, along with authorising them to penalise those who burn waste in the open, comes as winter knocks on the capital's door, a time which sees particulate matters in air rising to dangerous levels.
"In pursuance to NGT orders, SDMs along with Tehsildars are hereby authorised to carry out surprise inspection/special drive for dust control measures in the construction activities of plots with build up area between 400 sq m to 20,000 sq m," the order issed by Director (Environment) Anil Kumar said.

"Dust emissions from construction sites will be completely controlled by all authorities and the vehicles used for transportation of building material shall be properly cleaned before it is permitted to ply on the roads," the bench had said while asking the builders to create a green belt by planting trees.
