This bill serves as the primary appropriations act for energy and water development and related agencies for the fiscal year ending September 30, 2027. It meticulously details funding allocations across several major federal entities responsible for critical infrastructure, natural resource management, and energy security. The legislation aims to ensure the continued operation, maintenance, and development of essential services and strategic programs nationwide. Within Title I , the bill appropriates significant funds to the Corps of Engineers—Civil for its authorized functions. This includes $175,000,000 for investigations into river and harbor, flood control, and ecosystem restoration needs, and $2,382,000,000 for construction of such projects, with specific amounts derived from the Harbor Maintenance Trust Fund and Inland Waterways Trust Fund.

The bill also includes specific policy directives, such as requiring independent oversight for high-hazard nuclear facilities and restricting the use of funds for certain construction projects without independent cost estimates. Notably, it prohibits the sale of Strategic Petroleum Reserve products to entities controlled by the Chinese Communist Party and restricts access for non-U.S. citizens from Russia or China to nuclear weapons production facilities. Title IV appropriates funds for several Independent Agencies , including the Appalachian Regional Commission ($200,000,000), the Defense Nuclear Facilities Safety Board ($42,000,000), and the Delta Regional Authority ($32,000,000).
