India: The Maharashtra Pollution Control Board (MPCB) has released new guidelines for ready-mix concrete plants situated in Mumbai Metropolitan Region (MMR). The Free Press Journal newspaper has reported that the new guidelines require new static plants within municipal limits to obtain special MPCB approval, while new and existing plants outside of municipal limits must establish a 500m buffer zone. New ready-mix concrete plants at building sites must have a minimum project area of 2000m2 and existing ones must fully enclose their operations. Plants at building sites must dismantle their operations within a month after completing 70% of works at the site. Operators of ready-mix concrete plants in MMR must additionally provide new bank guarantees in favour of the MPCB.
The move purportedly aims to reduce air pollution in Mumbai. 11 of 26 monitoring stations in the city recorded poor air quality on 2 December 2024. Poor air quality indicates a high concentration of PM2.5 or PM10 inhalable particulate matter, which are present in smog.
