The fight against the Wallarah 2 coal project heads to Canberra today.
Two reps from the Australian Coal Alliance will sit down with Environment Minister Josh Frydenberg this afternoon, to ask him to block the development due to concerns about its impact on the Central Coast's water catchment.
The ACA's Allan Hayes says this is despite the state's Planning Assessment Commission recommending its approval back in January
"The Federal Government's own expert Committee has recommended this mine should not proceed," Mr Hayes told the newsroom last week.
"They said it would have an detrimental impact on an already stressed water catchment. I believe Mr Frydenburg should be rejecting the mine based on his own committee's recommendation."
Mr Frydenburg has until March 7th to veto the Planning Assessment Commission's decision to approve the underground coal mine.
While Mr Hayes says the fight will continue even if the Minister doesn't reject the mine.
"The community is going to challenge the decision in the Land and Environment Court, we are preparing a brief for Senior Counsel at the moment. So we will continue to bat on if we have to."
