As air pollution levels continue to rise in Mumbai, the Brihanmumbai Municipal Corporation (BMC) has revised guidelines issued last year for construction sites. The civic body will also form squads at the ward level to visit construction sites and act if guidelines are flouted.

After a detailed discussion at the meeting held on Monday, civic chief Bhushan Gagrani instructed that sensor-based air pollution monitoring systems be installed at all construction project work sites and immediate action to be taken if pollution levels are detected above the limit. In addition, 25-foot-high barricading has been made mandatory for all projects being carried out by the BMC and Metro authorities, including bridges and flyovers. Construction-related guidelines are applicable to all private, government and semi-government authorities including the Slum Rehabilitation Authority, Maharashtra Housing and Area Development Authority, Maharashtra Industrial Development Corporation, Maharashtra State Road Development Corporation, Mumbai Metropolitan Region Development Authority, Mumbai Port Trust, Airports Authority of India and Railways.

Enforcement teams comprising two engineers, a police officer and a marshal will visit the premises concerned. If it is found that the guidelines are not being followed stop-work notices will be issued and the site will be sealed immediately. The Maharashtra Pollution Control Board (MPCB) will simultaneously monitor the air pollution emitted by various industries.

Guidelines issued by the civic body

. It is mandatory for all project proponents to erect a 35-foot-high sheet/metal cover around construction projects over 70 metres.
