EDDINGTON, Maine — Town planners considering a Hampden contractor’s proposal to create a ledge quarry on Fox Hill decided Thursday to ask for an independent sound study for the project.

“No decision has been made” on whether to approve the quarry application by earthwork contractor Hughes Bros. Inc., Town Manager Russell Smith said Friday. “[The planning board] did decide they are going to get an independent noise study done.”

The project is on the planning board’s agenda for the April 10 meeting.

On Tuesday, Hughes filed a lawsuit against Eddington, claiming that planners and selectmen met illegally in January concerning a possible moratorium affecting the project. The lawsuit was filed the same day a public hearing was held on the proposed 180-day quarry moratorium that was started by a citizens’ petition in January.

The six months would provide planners time to create local rules regarding the operation of quarries, town leaders have said. Residents have voiced concerns about safety, noise and dust associated with Hughes’ project.

Hughes’ first application, for a 10-acre quarry, was denied by the Eddington Planning Board after a two-hour review in October. The most recent application seeks a quarry between 5 and 20 acres.

The lawsuit was filed in Penobscot County Superior Court alleging violations of Maine’s Freedom of Access law, and asks, amongst other things, that the citizens’ vote on the moratorium not be held.

The upcoming special town meeting to vote on the quarry moratorium is 6:30 p.m. Tuesday, April 8, at Eddington Elementary School.
