The Committee on Energy and Commerce is the oldest standing legislative committee (established 1795) in the U.S. House of Representatives and is vested with the broadest jurisdiction of any congressional authorizing committee. The Energy and Commerce Committee is at the forefront of all issues and policies powering America’s economy, including our global competitive edge in energy, technology, and health care. The Subcommittee on Oversight and Investigations is led by Chairman John Joyce (PA-13) and Ranking Member Yvette Clarke (NY-09).
This hearing examines the collapse of D.C. Water's Potomac Interceptor on January 19th, which released over 240 million gallons of untreated sewage into the Potomac River. The session focuses on the causes of the failure, the resulting environmental and public health risks, and the need for better oversight of aging wastewater infrastructure to prevent future disasters.
Good morning and welcome to today's hearing titled Corrosion, Collapse, and Cleanup.
Examining the Potomac Interceptor Collapse. Today's hearing will examine the collapse of
D.C. Water's Potomac Interceptor, a 54-mile sanitary sewer system that runs through parts
of Virginia, Maryland, and D.C. The collapse, which occurred on January 19th, resulted in
hundreds of gallons of untreated sewage overflowing onto nearby land and down the Potomac River.
This incident raised serious concerns about the resilience of critical wastewater infrastructure
and the impact that collapse or break like this can have on our communities,
including on safe drinking water, public health, the environment, local businesses.
The Potomac Interceptor is a vital component of the region's critical wastewater infrastructure.
When it failed, it caused over 240 million gallons of wastewater to overflow into the Potomac River,
threatening water quality, ecosystems, and the health of surrounding communities that rely on
this river for recreation, for fish and shellfish harvesting, and safe water drinking water once it
has been treated. Fortunately, because of where the collapse happened, the incident did not affect
safe drinking water. But if the break had happened just a few miles upstream, it would
have been a completely different story. Still, the collapse had far-reaching impacts on the region.
From a public health perspective, exposure to untreated wastewater can carry harmful pathogens
and pollutants, posing serious health risks to anyone who might be near the affected areas.
Environmentally, wastewater discharge can degrade aquatic habitats, harm wildlife,
and have impacts on native species. Economically, the effects ripple outward,
impacting local businesses, tourism, fisheries, some of which claim they have lost thousands
of dollars of revenue due to public perception of the cleanliness of the river following this
incident. This incident raises questions about the management and oversight of this critical
infrastructure. What led to the collapse? Was this failure preventable? Were there warning
signs that were being ignored or even missed? Did permitting requirements create unnecessary
delays in moving forward with needed repairs? Given the age and the condition of the Potomac
Interceptor, what is known about other vulnerabilities in the pipe and what is being
done to prevent another break or collapse from eventually or possibly happening? Equally
important is understanding the roles and the responsibilities of other entities as it relates
to the Potomac Interceptor. D.C. Water owns and operates the Potomac Interceptor, but multiple
agencies and jurisdictions have roles and responsibilities with respect to permitting
and regulatory oversight or have helped respond to the collapse, including federal partners such
as the U.S. Environmental Protection Agency, the U.S. Army Corps of Engineers, and the National
Park Service, as well as state and regional authorities. Today's hearing is about identifying
failures or gaps, strengthening oversight, and ensuring that our infrastructure systems are
equipped to protect the public and the environment in face of growing demands and aging assets.
We owe it to the American people to fully understand the causes and the consequences
of this failure and to take meaningful steps to prevent similar incidents in the future.
While this hearing will focus on the Potomac Interceptor, aging wastewater infrastructure is
a nationwide problem. A thorough investigation into this led up to this incident and the response
following it is critical to establish how best to repair similar infrastructure and to prevent
another large scale spill. The facts established by this hearing can help us protect the health
and the safety of communities that all of us represent. I want to thank our witnesses for
being here today. We look forward to hearing from you to learn more about the incident
and the lessons learned.
