The EPA has filed a lawsuit against a large sewer authority in Pennsylvania for illegally discharging over a billion gallons of untreated sewage into a nearby river. The complaint seeks fines of up to $37,000 per day for violations between 2004 and 2009, and $37,500 from January 2009 onward. Allegations include failure to submit long-term plans, properly maintain its system, report sewage discharges and meet requirements of a previous EPA order.
