State and federal officials are investigating the source of a small weekend oil spill in the Kennebec River in Clinton that observers said covered up to a mile of shoreline. The Maine Department of Environmental Protection notified federal officials Sunday about the spill, according to a report obtained by the Bangor Daily News. The spill involved an industrial-grade lubricant called No. 6 oil, sources said. State officials are working with their federal counterparts to determine the source and size of the spill, a DEP spokesperson said Thursday. The spill occurred downstream of Sappi’s Somerset Mill in Skowhegan.
