33 U.S.C. § 579d: Deauthorization of inactive projects

a lack of local support; a lack of available Federal or non-Federal resources; or an authorizing purpose that is no longer relevant or feasible; to create an expedited and definitive process for Congress to deauthorize water resources development projects and separable elements that are no longer viable for construction; and to allow the continued authorization of water resources development projects and separable elements that are viable for construction. planning, design, or construction was not initiated before January 4, 2025 ; or planning, design, or construction was initiated before January 4, 2025 , but for which no funds, Federal or non-Federal, were obligated for planning, design, or construction of the project or separable element of the project during the current fiscal year or any of the 10 preceding fiscal years. The Secretary may develop the preliminary list from the comprehensive construction backlog and operation and maintenance reports developed pursuant to section 579a(b)(2) of this title . prepare a proposed list of projects for deauthorization comprised of a subset of projects and separable elements identified on the preliminary list developed under paragraph (1) that are projects or separable elements described in subsection (a)(1), as determined by the Secretary; and include with such proposed list an estimate, in the aggregate, of the Federal cost to complete such projects. For purposes of subparagraph (A), the Federal cost to complete shall take into account any allowances authorized by section 2280 of this title , as applied to the most recent project schedule and cost estimate. The Secretary shall solicit comments from the public and the Governors of each applicable State on the proposed deauthorization list prepared under paragraph (2)(A). The public comment period shall be 90 days. considering any comments received under paragraph (3); and revising the proposed deauthorization list prepared under paragraph (2)(A) as the Secretary determines necessary to respond to such comments. identifies each project or separable element on the proposed deauthorization list that is not included on the final deauthorization list; and describes the reasons why the project or separable element is not included on the final deauthorization list. submit the final deauthorization list and appendix prepared under subsection (b)(4) to the Committee on Transportation and Infrastructure of the House of Representatives and the Committee on Environment and Public Works of the Senate; and publish the final deauthorization list and appendix in the Federal Register. The Secretary shall not include in the final deauthorization list submitted under paragraph (1) any project or separable element with respect to which Federal funds for planning, design, or construction are obligated after the development of the preliminary list under subsection (b)(1)(A) but prior to the submission of the final deauthorization list under paragraph (1)(A) of this subsection. A project or separable element of a project may not be identified on the proposed deauthorization list developed under subsection (b), or the final deauthorization list developed under subsection (c), if the project or separable element received funding for a post-authorization study during the current fiscal year or any of the 10 preceding fiscal years. For purposes of this section, if an authorized water resources development project or separable element of the project has been modified by an Act of Congress, the date of the authorization of the project or separable element shall be deemed to be the date of the most recent such modification. Any water resources development project, or separable element of a project, authorized for construction prior to November 17, 1986 , for which construction has not been initiated prior to December 27, 2020 , or for which funds have not been obligated for construction in the 10-year period prior to December 27, 2020 , is hereby deauthorized. the name of each project, or separable element of a project, deauthorized by paragraph (1); and the estimated current value of each such project or separable element of a project. the Secretary provides to the Committee on Transportation and Infrastructure of the House of Representatives and the Committee on Environment and Public Works of the Senate a post-authorization change report that updates the economic and environmental analysis of the project or separable element; and the Committee on Transportation and Infrastructure of the House of Representatives and the Committee on Environment and Public Works of the Senate take appropriate action to address any modifications to the economic and environmental analysis for the project or separable element of the project contained in the post-authorization change report. The term “post-authorization change report” has the meaning given such term in section 2282e(d) of this title . a feasibility report developed under section 2282 of this title ; a feasibility study, as defined in section 2215(d) of this title ; or demonstrates a Federal interest; and requires additional analysis for the project or separable element.
