Mumbai Authorities Tighten Pollution Norms for Construction and RMC Plants
Mumbai is working to make the air cleaner, especially around construction sites.
City officials and pollution control experts met to talk about a problem: Ready-Mix Concrete (RMC) plants, which are needed for building, are sometimes too close to homes and make a lot of dust.
If these plants take up too much space at a construction site, over 70%, they will have to be moved.
This is because the dust can make people sick.
They are also making sure all construction sites cover up their dust with nets and spray water.
They even banned fires at construction sites in winter.
Over the past year, they checked many construction sites and told some to stop working until they followed the rules.
Mumbai authorities (MPCB and BMC) are implementing stricter air pollution control norms for RMC plants and construction sites.
RMC plants occupying more than 70% of a construction site must be relocated due to pollution and health risks.
Measures include covering construction sites with green nets, regular water sprinkling, and wheel-washing facilities at exits.
During January-September 2025, thousands of construction sites received notices for violating pollution norms.
The BMC has also banned wood burning and bonfires at construction sites during winter to improve air quality.
