Wyong Council is the latest local body to attempt to ban mining in the region.
The Council will ask the State Government to pass legislation to protect its valleys from mining, the Express Advocate reports.
Councillor Sue Wynn stated that mining in the region could potentially damage aquifers and area’s water catchment.
It comes as Wallarah Coal and its backer Korean Resources (KoRes) make another push for its proposed Wallarah 2 coal mine.
The miner is again looking to put forth a proposal to mine under the Yarramalong and Dooralong valleys on New South Wales’ Central Coast.
New requirements issued by the NSW Planning and Infrastructure department are reportedly more stringent than those previously in place.
According to opponents of the mine, it is unlikely that Wyong Areas will be able to meet this higher standard.
Australian Coal Alliance spokesperson Alan Hayes told the Advocate that "it’s all about the impact on the water supply.
"No matter what the company says or does it is clear there will be an impact and they can’t escape from that.
"The issues are quite complex but the director-general has listened to the community and wants rigorous requirements met before any application for mining is lodged,” he said. “We doubt very much that those requirements can be met, he added"
However, the miner refuted this, stating that "the project’s refusal by former minister for planning, Tony Kelly, was not about any impact on the region’s water supply.
"This was because four separate assessments concluded that any potential impacts from the proposed mine on the region’s water supply system were minimal and none justified refusal."
Wyong Council is just the latest in a string of local council to push for a ban on mining in its region.
