Advocates are asking Governor Cuomo to halt the construction of a power plant in Orange County and using the federal probe into former aide Joe Percoco to make their case.

Protect Orange County says they are planning to upload about 10,000 pages of documents to their website in the next few days. They say some of those documents may tie the project to Percoco through payments made to his wife by Chris Pitts LLC, a company by the same name as a former consultant to the company developing the project.

The group has organized against the project from Competitive Power Ventures because of environmental concerns surrounding the construction of a new plant. They say the approval process has been smooth for CPV because of “public relationships” within the community and state.

Lead agency status was given to the town of Waywayanda Planning Board for the almost $1 billion project rather than the Department of Environmental Conservation, which the group has also called into question. They say aside from their environmental concerns, the approval process has been one-sided.

“What was revelatory was the pattern of indifference,” said Pramilla Malick from Protect Orange County. “I think when we raised issues, the fact that we never got a response was very telling.”

Cuomo has directed his administration to suspend regulatory communications with CPV following the news of U.S. Attorney Preet Bharara’s investigation into Percoco. Construction has already started at the site in Waywayanda, though the plant must still receive final approval from the state.

To operate, the plant still has to be approved for an interconnection to the Marcy South Line through NYPA and a lateral pipeline to the Millennium Pipeline. Both approvals are on hold.

“The CPV plant has not been approved,” Cuomo said Monday. “It’s not like the plant is operating. There was a conditional, early approval. They have to do a final agreement which has never been done.”

Advocates from Protect Orange County say withholding that final approval is not enough. They’re asking for the project to be stopped, and ultimately denied.

“The very first thing one should do is halt construction,” Malick said. “The harm is underway. There is already irreperable harm to the endangered species habitat.”

Though the group did not present clear evidence to reporters that would link Percoco to the power project at a press conference Thursday, they say the federal investigation should be enough to back up their argument.

“Why on earth would you allow a project to go forward when there is now clear suspicion on whether those approvals were proper in the first place,” Malick said.

Advocates also said they had “heard of Percoco” in association to the project, though whether that was before news broke on the investigation or after was unclear.

A spokesman from CPV did not immediately return a call for comment.
