BATH, Maine (AP) – A Maine environmental group is suing over lights installed on a set of power line towers.

The lawsuit filed in Superior Court by the Friends of Merrymeeting Bay contends there were no lights at a pair of 195-foot Central Maine Power Company towers on the Kennebec River until the utility replaced the towers. Since then it says the light pollution is having an adverse impact on people and wildlife.

The group also is opposed to the utility’s proposal to reduce the amount of time the lights are in operation with a radar to detect approaching aircraft.
