Responsible Containment Reauthorization

Summary#

This bill would change the Uranium Mill Tailings Radiation Control Act of 1978 to extend the authorization for a specific uranium mill tailings disposal site in Mesa County, Colorado. It removes the phrase ", or September 30, 2031, whichever comes first" from Section 112(a)(1)(B), so the site is authorized to operate until it is filled to its designed capacity. The bill was introduced on March 5, 2026, and referred to the Senate Committee on Energy and Natural Resources. Sponsors listed are Senators John Hickenlooper, John Curtis, and Michael Bennet.

What it means for you#

  • The site in Mesa County may continue receiving and containing uranium mill tailings until it reaches its designed capacity, rather than stopping on a specified calendar date.
  • If you live or work near the site, this change affects the legal authorization for how long the site can operate, but no operational, health, or safety details are provided in the bill text.
  • For most people outside the area, there is no specific new information about services, permits, or changes to daily life in the bill text.
