Supreme Court has asked the Centre and Delhi government to positively respond to a plea seeking levy of pollution compensatory charges, along with toll tax, on commercial vehicles plying in the national capital. Bench of the Chief Justice of India and Justices Arun Mishra and Adarsh Kumar Goel said rising level of pollution in NCR is a serious issue and they want a positive response. <br/><br/>Seeking enforcement of principle of Environment Law that the polluter has to pay, senior advocate Harish Salve, termed the pollution situation as alarming and sought urgent intervention before it worsens further. Mr. Salve, during the hearing, referred to the report of the Environment Pollution Prevention and Control Authority for NCR said a large number of commercial vehicles opt Delhi and NCR roads, instead of the highways, as it is cheaper to traverse through the capital city.<br/><br/>The apex court has now asked Solicitor General Ranjit Kumar, appearing for the Centre and the counsel for the Delhi government and civic agencies to come prepared on Thursday when it will take up the fresh plea filed by Salve. Earlier, it had agreed to hear the plea seeking directions for the Centre, Delhi Government and the Municipal Corporation of Delhi to ensure that commercial vehicles entering the city of Delhi are required to pay a sum of not less than 600 rupees for Light Commercial Vehicle- 2 axle and not less than 1200 rupees for 3-axle and above. This pollution compensatory charge will be imposed in addition to the toll charge imposed by MCD.
