The New South Wales environment watchdog says a plan to extend the life of a Hunter Valley coal-mining complex to 2050 is the “largest coal-mining proposal ever put forward” in the state.
Plans by Yancoal and Glencore to keep its joint-venture Hunter Valley Operations (HVO) mines in the Upper Hunter region going would see almost 30m tonnes of CO2 released, the EPA said in a letter to the state’s planning department.
