Their comments are a new twist in a story which has taken many turns and all of a sudden has become Wellington's hottest debate.

Wellington mayor Rod Buhr called for an urgent review into the power station last week and was backed by Deputy Premier Troy Grant.

After learning of the wrangle, the Stewarts, descendants of the traditional owners of the Wellington area, joined a packed crowd at the Wellington Shire Council chambers, claiming there had been no consultation on how this could affect Wiradjuri land.

"They have had no association with the community, especially the Aboriginal community," Dot Stewart said.

"We don't want it, it is too close to Wellington.

"We go a long way back; it is our blood home since time immemorial.

"We are the traditional owners, descendants of the apical ancestors of this traditional country."

Her sister Diane Stewart said she had many concerns about how this might affect native vegetation and wildlife.

"Not to mention the clearing of cultural heritage, scar trees, Aboriginal artefacts and burial sites," Diane said.

"We are so concerned, we fully support Nat Barton in his endeavour to have it stopped completely."

The Stewarts said they were concerned not just about Wellington, but all Wiradjuri land between Wellington and Young.

They came from Dubbo to support Nat Barton and noise expert Martin Sannikka at Wednesday night's meeting.

Mr Barton, whose family has lived on Nanima homestead (since the 1880s) next to where the power station would be situated, has been financially devastated in part by the battle against ERM Power.

"This station has already done huge damage to Nanima. They've deliberately put me in this position," he said.

"They knew about it for a long time. Whether it is right or not will be determined in court, but by the time I appeal it will be turned to nothing."

He suggested the noise data (including the total power sound level at the source) be disclosed by ERM and reassessed by an independent and properly qualified expert.

"Wellington Council should also do their diligence and visit Uranquinty and see for themselves the severe impact," he said, adding that hardened lawyers had been shocked by the stories of the people they had to represent there.

Mr Barton also suggested council complete an application under the Freedom of Information act pertaining to "substantial commencement" and the report be made publicly available.

He then recommended council seek legal advice as to the impact of the "nuisance law" on council and ratepayers' liability and that Wellington Council take immediate steps to protect the heritage furniture and property part of the heritage listing of Nanima homestead and stop the trustee from selling it by getting in touch with council's Sydney lawyers to request an urgent injunction from the duty judge in the Supreme Court of NSW.

In his presentation to council, Martin Sannikka accused ERM Power of deliberately misleading the public through "mathematical trickery".

Following the meeting, ERM Power told the mayor they were prepared to bring a sound expert to meet Martin Sannikka as well as fly a delegation to their power plant in Oakey, near Toowoomba.

Council moved to organise transport for any concerned residents to travel to Toowoomba and pay for two thirds of the bus costs.

Meanwhile the petition in Wellington against the station already has 600 signatures.
