An investigation by The Washington Post reveals that a prolonged environmental review pushed back work that was initially proposed in 2018.
The D.C.-area utility responsible for a massive sewer line that failed catastrophically in January had planned to reinforce the aging section years ago but repeatedly delayed construction as federal officials studied potential environmental impacts, including risks to a blue wildflower and an endangered bat species, a Washington Post investigation found.
D.C. Water asked the National Park Service for permission to fast-track repairs in 2018, after inspectors found widespread corrosion and detached rebar in one area of the six-foot-wide concrete pipe that runs under federal parkland in Maryland, records show. The utility sought to strengthen a three-quarter-mile section that included the point that later ruptured.
Left unaddressed, it warned, the corrosion could “result in a catastrophic failure leading to the release of raw sewage into soil, groundwater, and waterways,” records show.
But the National Park Service’s environmental review dragged on for years and was still not complete when the pipe collapsed — a delay that experts said appeared to flout a 2020 federal rule requiring such examinations be done within one year.
