Earlier this year the federal EPA approved a new injection well for Plum Borough in Allegheny County, PA (see Federal EPA Approves Permit for Plum, PA Wastewater Injection Well). Although federal approval is necessary, so too is state approval. The PA Dept. of Environmental Protection (DEP) held a public hearing Monday night to elicit input. Around 60 people showed up. All 17 who spoke at the hearing were against the proposed injection well.
