Coal India’s subsidiary -- Mahanadi Coalfields (MCL) -- has complied with one of the two notices it received for violating environmental norms from Pollution Control Board Odisha. The notices were issued to MCL's two coal mines - Samaleswari and Lajkura open-cast mines in the western region of the state.
The pollution regulator, during routine inspection, found that the sludge treatment plant in one of the mines was defunct while the water sprinkling systems were inadequate in another.
Coal India is the world’s largest coal mining company. It also produces non-coking coal and coking coal of various grades for diverse applications.
