The Maine Board of Environmental Protection has denied a request by Calais LNG to postpone a meeting set for Wednesday to update the state on its attempts to line up new investors for the $1 billion project.

In a letter late Monday, BEP Chair Susan Lessard said tomorrow’s meeting will proceed on schedule. At the conference, parties will have an opportunity to comment on the impact of the most recent request to keep the application on hold until mid-October, she said.

The company is trying to develop a liquefied natural gas terminal in Calais. The proposed project is opposed by some fishermen and environmental groups over concern for tanker traffic and a route that takes ships through Canadian waters.

In August, Calais LNG asked the board for time for its lead investor, GS Power Holdings, to find a new financial partner for the project. The new financing was supposed to be lined up by Sept. 11.

But a lawyer for the company wrote to the board Monday asking to postpone the meeting, and seeking another 30 days before providing a status report. He said Calais LNG has narrowed the candidates to two investors, one with access to a significant supply of natural gas, and the other involved in the global commodities market.

Environmental groups and other opponents have complained that Calais LNG should withdraw its permit application until it lines up financing. They are expected to press those requests at Wednesday’s meeting.
