H.R. 6353 would waive certain federal historic preservation review requirements for water infrastructure projects. Specifically, it exempts public water system upgrades and treatment works improvements from Section 106 review under the National Historic Preservation Act, provided the entity carrying out the project requests this exemption from the responsible federal agency. The bill affects state and local governments, water utilities, and other entities that manage public water systems seeking to modernize their infrastructure. The legislation includes no specific funding allocations or implementation timelines beyond making the waiver available upon request. The bill was referred to the House Committees on Transportation and Infrastructure, Energy and Commerce, and Natural Resources in December 2025.
