The Environment Protection Authority has fined two companies over separate pollution incidents in Newcastle.

Multiplex has been fined $15,000 after a pollution control structure at the John Hunter Health and Innovation Precinct construction site failed, sending sediment-laden water into nearby creeks and rivers.

Kooragang Bulk Facilities has also been fined $15,000 after almost 2 tonnes of alumina dust was released from a hopper, causing alleged air pollution, with some ending up in the Hunter River.
