A circuit bench headed by NGT Chairperson Justice Swatanter Kumar asked the Himachal Pradesh government and the state pollution control board to issue notice to all such builders within two weeks and ask them to comply with the direction without default.
"Report of compliance should also be submitted before the next date of hearing. It shall also deal with the issue of storm water drain carrying municipal solid waste and other pollutant to the source of water," the bench, also comprising Justice Dalip Singh, said in its order passed recently.
The green panel also sought complete data as to how many drains carry sewage in the entire city of Shimla within the municipal corporation.
The matter is listed for next hearing on July 21.
The NGT was hearing a plea filed by Shimla-based advocate Abhimanyu Rathor seeking direction to concerned agencies to formulate an action plan for the collection and disposal of municipal solid waste.
