The mining company embroiled in a New South Wales corruption inquiry has pleaded with New South Wales state MPs to allow a controversial mine site to go ahead.
Cascade Coal wants to develop Mount Penny, on land owned by the family of former Labor minister Eddie Obeid.
Last night the directors of the company wrote to all New South Wales MPs arguing it is in the state's best interest to develop the $1 billion mine.
Greens MP John Kaye says the directors of Cascade Coal mount an argument that the state should not move against their licence to mine coal at Mount Penny.
"They put forward a number of arguments, none of which, I must say, are anywhere near persuasive on me," Mr Kaye said.
"But those arguments go to the fact that they claim they weren't involved in any alleged corruption, and they claim that there are benefits associated with proceeding with the mine that would counteract any supposed losses from, if there had been a corrupt obtaining of the licences for the mine."
Although the directors claim they did nothing wrong and the tender process was complied with, Mr Kaye says there are "severe allegations" surrounding this mine and the matter cannot be finalised until ICAC reports in the middle of the year.
"There are huge concerns surrounding the obtaining of the licence for this coal mine, such that there needs to be an independent investigation," he said.
"ICAC is currently proceeding with that investigation.
"I think going ahead with that mine before ICAC has reported, and before the people of New South Wales understand what they may or may not have lost in that process would be unwise.
"It is important for, not just for the money that might be lost, but also for the reputation for the state that this matter be cleared up before Cascade goes ahead."
The directors say the benefit to the state would benefit from the project getting the green light to proceed, but Mr Kaye remains unconvinced.
"These figures are arguable, there are greenhouse costs, there are local community costs that the directors don't even mention," he said.
"And it's always so that the benefits of coal mines are overstated by their proponents.
"If the directors are arguing this on the basis of what the benefits would be for the state, then we would like to see an independent investigation which includes, for example, the enormous amount of carbon dioxide that this coal will produce."
Premier Barry O'Farrell, declined to be interview by the ABC today.
But last month Mr O'Farrell said Cabinet had agreed to apply a broad public interest test in consideration of the project, if Cascade Coal resubmits a project application for Mt Penny to the Planning Department.
