(AP)- Governor John Baldacci says the National Guard has agreed to conduct a full environmental review as part of its proposal to lower the flight deck for training missions over western Maine.

Baldacci says confirmation was given to Col. Donald McCormack of the Maine Air National Guard by the Air National Guard Readiness Center at Andrews Air Force Base in Maryland.

Under the proposal, National Guard F-15 pilots from Massachusetts and F-16 pilots from Vermont would be allowed to fly as low as 500 feet over the hills and mountains of western Maine.

It’s unclear whether the full environmental impact statement sought by the governor will alter the timetable for the proposed changes. The National Guard plans to file its proposal with the Federal Aviation Administration this spring, and hopes to begin the training flights in October.
