WASHINGTON, D.C. – Today, Congressman Brett Guthrie (KY-02), Chairman of the House Committee on Energy and Commerce, and Congressman John Joyce, M.D. (PA-13), Chairman of the Subcommittee on Oversight and Investigations, announced a hearing titled Corrosion, Collapse, and Clean-Up: Examining the Potomac Interceptor Collapse.

“Since launching our investigation in February, the Committee has been working to understand what led to DC Water's Potomac Interceptor collapse that caused one of the largest sewage spills in American history,” said Chairmen Guthrie and Joyce. “The resilience of our wastewater infrastructure systems remains critical to protecting the health and safety of our communities, including safe drinking water and the environment. This hearing will help to understand what was known about the condition of the Potomac Interceptor prior to this incident, the emergency response and cleanup efforts that have been underway since the collapse, and how future incidents may be prevented.”
