TNPCB: Latest news

Tamil Nadu Pollution Control Board (TNPCB) takes action against industries for illegal discharge of effluents into the Mettur dam

In March 2021, the Tamil Nadu Pollution Control Board (TNPCB) informed the southern bench of the National Green Tribunal (NGT) that it had initiated action against the industries responsible for the illegal discharge of effluents into Mettur dam.

The Board began proceedings based on a report submitted by an expert committee formed by the NGT. There were about 40 industries in the region producing fertilisers and other products based on hazardous chemicals.

Madras High Court extends stay restraining state from permitting new stone crushing units

Considering the scale of pollution caused due to stone crushing units and the flouting of rules by industries, the Madras High Court has extended the stay restricting the state from permitting new stone crushing units.

In 2019, the Board had removed the minimum distance rule that required stone crushers to maintain a 1-kilometre distance between any two units, after a proposal made by the Stone Crushers Association (SCA). The move was aimed at encouraging the production and use of M-Sand in construction instead of river sand. M-Sand or manufactured sand is produced by crushing blue metal jellies either in stone crushers in an extended facility or in standalone M-Sand units. However, many environmental activists had opposed the move as reducing the distance would bring the stone crushing units closer and result in the release of a huge amount of particulate matter into the air.

The court said that the board acted against the recommendations of the National Environmental Engineering Research Institute (NEERI), in 2019. The NEERI had earlier recommended in its resolutions, to maintain a 1-km distance between one stone crushing unit and the next unit. The court further added that the relaxation of norms was also made applicable for existing stone crushers and M-Sand units. The court issued a stay order concerning the opening or re-opening of stone crushing units.
