Thanks to a reader for passing on the warning.
“September 4, 2015—This morning, a team of inspectors from the Department of Energy and Environment (DOEE), National Park Service (NPS) and Pepco discovered a spill of insulating oil to Rock Creek along Beach Drive, immediately south of Klingle Road NW.
The source of the insulating oil spill is believed to be a leak in a Pepco transmission line. Pepco has isolated and contained the immediate spill area and is currently working to pinpoint the exact location of the leak and make repairs to the transmission line.
The insulating oil is classified as non-toxic. However, to ensure the health and safety of all park visitors, including pets, contact with this area of Rock Creek should be avoided until further notice.
DOEE, the National Park Service, and the U.S. Environmental Protection Agency will continue to monitor the situation and are coordinating with Pepco to ensure the spill is properly contained and remediated.”
The Washington Post reports:
“On Sunday, Sean Kelly, a Pepco spokesman, said that the source of the leak had been “clamped” but that repair work and environmental clean-up would continue for weeks.”
