Department of Environmental Protection Clean Stream Act Violation?

I live in Southwestern, Pa. I reported a violation to the State Department of Environmental Protection (DEP)and the German township sewage officer (SO). The violation was, raw sewage from a restaurant/motel business was allowed to flow into a stream that emptied into the Monongahela river. (Clearly a violation of The Clean Stream Act)There is two other businesses in the area. Their septic systems were checked and wasn't causing the violation. The SO and DEP inspector stated all three businesses were at fault. There is plans for a sewage plant and etc. in the future. If they (the other two businesses)couldn't wait they would all have to install holding tanks. The SO stated he would make a cover for the storm drain opening to stop the smell from coming out of it. The workers at the businesses (all females) would have to remove the cover when it rains and cover it when rain stops. The stench from this is awful. Anyone coming to these businesses and the surrounding home owners complain about the smell. I believe the DEP inspector and the SO are using a scare tactic to keep the restaurant/motel out of trouble since they added more motel units and added a restaurant to the old septic system.The DEP states they don't enforce septic system laws it's up to the Townships Sewage Officer. What steps should be taken?
