O&I Hearing: Corrosion, Collapse, and Clean-Up: Examining the Potomac Interceptor Collapse

The House Committee on Energy and Commerce held an oversight hearing on May 21, 2026, titled "Corrosion, Collapse, and Clean-Up: Examining the Potomac Interceptor Collapse." The hearing focused on the January 19, 2026, collapse of the Potomac Interceptor, a critical 54-mile sanitary sewer pipeline serving parts of Virginia, Maryland, and DC, which resulted in the release of over 240 million gallons of untreated sewage into the Potomac River. Witnesses from the EPA, US Army Corps of Engineers, National Park Service, and DC Water testified about the incident, emergency response, remediation efforts, and ongoing challenges related to aging infrastructure and permitting delays. Key procurement-related discussions included the delayed environmental assessments and permitting processes that hindered timely repairs, the issuance and negotiation of emergency contracts by DC Water for repairs, and the coordination of federal resources under a presidential emergency declaration. The hearing also addressed the need for increased funding and streamlined permitting to prevent future infrastructure failures, with emphasis on asset management, technical assessments, and the importance of federal funding programs such as the Clean Water State Revolving Fund. Members questioned witnesses on the timeline of notifications, response actions, and the adequacy of current remediation and repair efforts. The hearing underscored the critical need for improved oversight, funding, and interagency coordination to maintain and upgrade aging water infrastructure and protect public health and the environment.
