Angry residents have met with the NSW Resources Minister to demand the suspension of a coal seam gas exploration licence.

Gloucester residents want AGL’s drilling program to be shut down and the region’s water supplies protected from the potentially-harmful gas project.

Community group Groundswell Gloucester met with Resources Minister Anthony Roberts to hand over a 600-page document outlining their concerns.

Operations remain suspended at the Waukivory test drilling site after the Environment Protection Authority found potentially toxic chemicals in flow-back water.

Groundswell Gloucester's John Watts said the extensive community-funded research shows a number of other flaws in AGL’s operations so far.

“We say that they have broken and breached, on many occasions, their obligation to effectively and honestly consult the community,” he said.

“Secondly, we say that AGL are now not a fit and proper company to hold a licence.

“And thirdly, we've identified some breaches by AGL of their environmental licence which we say would also indicate to the Minister that he should suspend the licence immediately.”
