Report: Massive DC Sewage Spill Caused by Environmental Review That Dragged on for Years

[martybegan]

From the beginning I knew there was more to this story. I work in the wastewater treatment field, and when I went to DCWASA's site, I saw that work was planned and ongoing in the area. While I don't agree that the review delay was the only cause of the failure, I can see it being a contributing factor to them having to wait years to go ahead with the full project to repair the defects.

Massive DC Sewage Spill Caused by Environmental Review That Dragged on for Years

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...

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...

A review by The Post of more than 2,600 public utility documents reveals how concerns about the removal of trees and vegetation, along with other environmental impacts, postponed repairs to the Potomac Interceptor. The pipe continued to degrade for more than seven years before it failed on Jan. 19 and released one of the largest spills of untreated wastewater in U.S. history.

Now there was a project going on addressing the interceptor, but I don't think it was the full project DCWASA was trying to implement. I've done preliminary work while still undergoing an impact statement, but I'm sure DCWASA couldn't do all it wanted to do because of the lack of the statement and permission from the NPS.
