The EPA should be in the docket along with the local and state governments. Especially all of the bureaucrats involved should be held personally responsible for Civil Rights violations, RICO and extortion. It wouldn't hurt to have some discovery to ID the neighbor snitch.
What did the local gov’t do wrong? They issued a building permit. Why is that wrong? Land use is a local issue. EPA wants to make it a federal matter, and stomp all over local governments. The Founding Fathers would be appalled.
