VALLEY FORGE, Pa. (AP) — Crews are working to replace a broken pipe at Valley Forge National Historical Park that has caused millions of gallons of raw sewage to flow into an environmentally sensitive creek that's a magnet for trout fishermen.
The 30-inch sewer main owned by the Tredyffrin Township Municipal Authority burst Wednesday morning. For hours after the break, a torrent of sewage spilled into Valley Creek at a rate estimated at around 5,000 gallons per minute.
The creek drains into the Schuylkill River. The National Park Service said all roads in the park will remain closed until the main is repaired.
State officials couldn't rule out the possibility of a fish kill from the sewage. The commission says fish eggs are also about to hatch and such a spill could kill the offspring.
