His call comes after the State Opposition slammed Environment and Climate Change Minister John Robertson for refusing to answer questions on the development in Parliament last week.

Mr Robertson said the power plant was a matter of planning, not environment.

Cr Rule said that was the problem.

The power plant was approved under Part 3A the controversial planning act clause which allows the Minister for Planning to sideline local councils and take control of the approval process.

Cr Rule said the section needed to be reviewed or abolished.

``Part 3A has gone way too far,'' he said.

``It should only be used for things like the Olympic Games or huge rail links, not on issues such as these.''

The Opposition appears to be in tune with the Labor mayor and has vowed to scrap Part 3A.

Opposition spokeswoman Catherine Cusack said: ``Wollondilly MP Phil Costa should be demanding that John Robertson support Campbelltown Council's calls for the Leafs Gully Power Plant to be assessed by federal Environment Minister Peter Garrett under the Environment Protection and Biodiversity Act.''

Mr Costa said he remained opposed to the plant.
