§183a — Title 10 Armed Forces | U.S. Code

Summary

Create a Clearinghouse inside the Department of Defense to review proposed wind, solar, power lines, or antenna projects that might hurt military flying, training, testing, or readiness. The Secretary of Defense must put the Clearinghouse under an Assistant Secretary, give it staff and money, and make rules so local military bases are consulted. When the Department of Transportation sends an application, the Clearinghouse must do a first check within 75 days. That check must say how big and how long any risk would be and list feasible, affordable ways to reduce the risk. If a risk is found, the Clearinghouse sends a "presumed risk" notice to the project applicant and to the State governor and asks for discussions and for the governor’s comments (the governor gets at least 30 days to reply). If later the Department decides there is no problem, the Clearinghouse must tell the applicant and the governor in writing. The Clearinghouse must also speed up planning tools, work with other agencies, make early outreach rules that ask developers to file a project area and preliminary layout at least one year before building if the project is in a military training route or in line-of-sight of certain DoD radars, protect proprietary data, and, if it finds no impact under the relevant aviation law, tell the Department of Transportation in writing within 5 business days. The Secretary must make a broader strategy that maps and rates geographic areas where projects could hurt military operations, gives a public notice-and-comment way to pick and update those areas, and posts the maps online. The Secretary can only formally object to a project if, after considering mitigation, the project would create an unacceptable risk to national security. For any proposed structures over 200 feet tall within 2 nautical miles of an active intercontinental ballistic missile launch facility or control center, the Secretary must find an unacceptable risk unless mitigation removes all those tall structures after a presumed-risk notice (this does not apply to structures approved before the National Defense Authorization Act for Fiscal Year 2024 or to repowered structures in the same place). If the Secretary finds an unacceptable risk, DoD must tell Transportation and report to Congress within 30 days explaining the impact, the mitigation tried, and why mitigation failed; the report can include a classified annex and the State agency will be told. The Clearinghouse can accept voluntary money from an applicant to help pay for DoD studies or mitigation. Actions here do not replace any review the Department of Transportation must do under federal aviation law. Key defined terms (one line each): adverse impact on military operations and readiness = harm to military flying, testing, or training that likely weakens warfighting ability; antenna structure project = a tower or similar that supports antennas near ICBM sites (with some older or approved exceptions); intercontinental ballistic missile launch facility or control center = sites at Francis E. Warren AFB, Malmstrom AFB, and Minot AFB; energy project = project to make or move electric power; governor = State chief executive; landowner = person owning the land for a proposed project; military installation, military readiness, military training route, and State = as used for military and geographic purposes in law.

Title 10, §183a

(a)(1)The Secretary of Defense shall establish a Military Aviation and Installation Assurance Siting Clearinghouse (in this section referred to as the “Clearinghouse”).

(2)The Clearinghouse shall be—

(A)organized under the authority, direction, and control of an Assistant Secretary of Defense designated by the Secretary; and

(B)assigned such personnel and resources as the Secretary considers appropriate to carry out this section.

(b)(1)The Clearinghouse shall coordinate Department of Defense review of applications for energy projects or antenna structure projects filed with the Secretary of Transportation pursuant to section 44718 of title 49 and received by the Department of Defense from the Secretary of Transportation. In performing such coordination, the Clearinghouse shall provide procedures to ensure affected local military installations are consulted.

(2)The Clearinghouse shall accelerate the development of planning tools necessary to determine the acceptability to the Department of Defense of proposals included in an application for an energy project or antenna structure project submitted pursuant to such section.

(3)The Clearinghouse shall perform such other functions as the Secretary of Defense assigns.

(c)(1)Not later than 75 days after receiving from the Secretary of Transportation a proper application for an energy project or antenna structure project under section 44718 of title 49 that may have an adverse impact on military operations and readiness, the Clearinghouse shall conduct a preliminary review of such application. The review shall—

(A)assess the likely scope, duration, and level of risk of any adverse impact of such energy project or antenna structure project on military operations and readiness; and

(B)identify any feasible and affordable actions that could be taken by the Department, the developer of such energy project or antenna structure project, or others to mitigate the adverse impact and to minimize risks to national security while allowing the energy project or antenna structure project to proceed with development.

(2)(A)If the Clearinghouse finds under paragraph (1) that an energy project or antenna structure project will have an adverse impact on military operations and readiness, the Clearinghouse shall issue to the applicant a notice of presumed risk that describes the concerns identified by the Department in the preliminary review and requests a discussion of possible mitigation actions.

(B)After the Clearinghouse issues a notice under subparagraph (A) with respect to an energy project or antenna structure project, the parties should seek to identify feasible and affordable actions that can be taken by the Department, the developer of such energy project or antenna structure project, or others to mitigate any adverse impact on military operations and readiness.

(C)A notice of presumed risk issued under subparagraph (A) is a preliminary assessment only and does not represent a formal objection pursuant to subsection (e). Discussions of possible mitigation actions under such subparagraph could favorably resolve any concerns identified in the notice of presumed risk.

(3)At the same time that the Clearinghouse issues to the applicant a notice of presumed risk under paragraph (2), the Clearinghouse shall provide the same notice to the governor of the State in which the project is located and request that the governor provide the Clearinghouse any comments the governor believes of relevance to the application. The Clearinghouse shall ensure that a governor has at least 30 days after the date on which the governor receives the notice of presumed risk to provide any such comments and shall provide detailed information and other information necessary to ensure that the governor can fully understand the nature of the presumed risk. The Secretary of Defense shall consider the comments of the governor in the Secretary’s evaluation of whether the project presents an unacceptable risk to the national security of the United States and shall include the comments with the finding provided to the Secretary of Transportation pursuant to section 44718(f) of title 49.

(4)If, after issuing the notices of presumed risk required by paragraphs (2) and (3), the Secretary of Defense later concludes for any reason that the energy project or antenna structure project will not have an adverse impact on military readiness, the Clearinghouse shall notify the applicant and the governor in writing of that conclusion.

(5)The Clearinghouse shall develop, in coordination with other departments and agencies of the Federal Government, an integrated review process to ensure timely notification and consideration of energy projects or antenna structure projects filed with the Secretary of Transportation pursuant to section 44718 of title 49 that may have an adverse impact on military operations and readiness.

(6)The Clearinghouse shall establish procedures for the Department of Defense for the coordinated consideration of and response to a request for a review received from another Federal agency, a State government, an Indian tribal government, a local government, a landowner, or the developer of an energy project or antenna structure project, including guidance to personnel at each military installation in the United States on how to initiate such procedures and ensure a coordinated Department response.

(7)The Clearinghouse shall develop procedures for conducting early outreach to parties carrying out energy projects or antenna structure projects that could have an adverse impact on military operations and readiness and to clearly communicate to such parties actions being taken by the Department of Defense under this section. The procedures shall provide for filing by such parties of a project area and preliminary project layout at least one year before expected construction of any project proposed within a military training route or within line-of-sight of any air route surveillance radar, airport surveillance radar, or wide area surveillance over-the-horizon radar operated or used by the Department of Defense in order to provide adequate time for analysis and negotiation of mitigation options. Material marked as proprietary or competition sensitive by a party filing for this preliminary review shall be protected from public release by the Department of Defense.

(8)If, in reviewing an application for an energy project or antenna structure project pursuant to paragraph (1), the Clearinghouse finds no adverse impact on military operations under section 44718(b)(1) of title 49, the Clearinghouse shall communicate to the Secretary of Transportation in writing, not later than five business days after making such finding, the following: “No Part 77 concerns, national security review ongoing.”

(d)(1)The Secretary of Defense shall develop a comprehensive strategy for addressing the impacts upon the military of projects filed with the Secretary of Transportation pursuant to section 44718 of title 49.

(2)In developing the strategy required by paragraph (1), the Secretary shall—

(A)assess the magnitude of interference posed by projects filed with the Secretary of Transportation pursuant to section 44718 of title 49;

(B)solely for the purpose of informing preliminary reviews under subsection (c)(1) and early outreach efforts under subsection (c)(5), identify distinct geographic areas selected as proposed locations for projects filed, or for projects that are reasonably expected to be filed in the near future, with the Secretary of Transportation pursuant to section 44718 of title 49 where the Secretary of Defense can demonstrate such projects could have an adverse impact on military operations and readiness, including military training routes or any active intercontinental ballistic missile launch facility or control center, and categorize the risk of adverse impact in such areas;

(C)develop procedures for the initial identification of such geographic areas identified under subparagraph (B), to include a process to provide notice and seek public comment prior to making a final designation of the geographic areas, including maps of the area and the basis for identification;

(D)develop procedures to periodically review and modify, consistent with the notice and public comment process under subparagraph (C), geographic areas identified under subparagraph (B) and to solicit and identify additional geographic areas as appropriate;

(E)at the conclusion of the notice and public comment period conducted under subparagraph (C), make a final finding on the designation of a geographic area of concern or delegate the authority to make such finding to the Deputy Secretary of Defense, an Under Secretary of Defense, a Deputy Under Secretary of Defense, or, in the case of a geographic area of concern related to an active intercontinental ballistic missile launch facility or control center, the Assistant Secretary of Defense for Energy, Installations, and Environment; and

(F)specifically identify feasible and affordable long-term actions that may be taken to mitigate adverse impacts of projects filed, or which may be filed in the future, with the Secretary of Transportation pursuant to section 44718 of title 49, on military operations and readiness, including—

(i)investment priorities of the Department of Defense with respect to research and development;

(ii)modifications to military operations to accommodate applications for such projects;

(iii)recommended upgrades or modifications to existing systems or procedures by the Department of Defense;

(iv)acquisition of new systems by the Department and other departments and agencies of the Federal Government and timelines for fielding such new systems; and

(3)The governor of a State may recommend to the Secretary of Defense additional geographical areas of concern within that State. Any such recommendation shall be submitted for notice and comment pursuant to paragraph (2)(C).

(4)The Clearinghouse shall make access to data reflecting geographic areas identified under subparagraph (B) of paragraph (2) and reviewed and modified under subparagraph (C) of such paragraph available online.

(e)(1)(A)The Secretary of Defense may not object to an energy project or antenna structure project filed with the Secretary of Transportation pursuant to section 44718 of title 49, except in a case in which the Secretary of Defense determines, after giving full consideration to mitigation actions identified pursuant to this section, that such project, in isolation or cumulatively with other projects, would result in an unacceptable risk to the national security of the United States.

(B)(i)In the case of any energy project or antenna structure project with proposed structures more than 200 feet above ground level located within two nautical miles of the geographic center of an active intercontinental ballistic missile launch facility or control center, the Secretary of Defense shall issue a finding of unacceptable risk to national security for such project if the mitigation actions identified pursuant to this section do not include removal of all such proposed structures from such project after receiving notice of presumed risk from the Clearinghouse under subsection (c)(2).

(ii)Clause (i) does not apply to structures approved before the date of the enactment of the National Defense Authorization Act for Fiscal Year 2024 or to structures that are re-powered with updated technology in the same location as previously approved structures.

(C)Any finding of unacceptable risk to national security by the Secretary of Defense under this paragraph shall be transmitted to the Secretary of Transportation for inclusion in the report required under section 44718(b)(2) of title 49.

(2)(A)Not later than 30 days after making a finding of unacceptable risk under paragraph (1), the Secretary of Defense shall submit to the congressional defense committees, the Committee on Commerce, Science, and Transportation of the Senate, and the Committee on Transportation and Infrastructure of the House of Representatives a report on such finding and the basis for such finding. Such report shall include an explanation of the operational impact that led to the finding, a discussion of the mitigation options considered, and an explanation of why the mitigation options were not feasible or did not resolve the conflict. The report may include a classified annex. Unclassified reports shall also be provided to the project proponent. The Secretary of Defense may provide public notice through the Federal Register of the finding.

(B)The Secretary of Defense shall notify the appropriate State agency of a finding made under paragraph (1).

(3)The Secretary of Defense may only delegate the responsibility for making a finding of unacceptable risk under paragraph (1) to the Deputy Secretary of Defense, an Under Secretary of Defense, or a Deputy Under Secretary of Defense.

(4)The Clearinghouse shall develop procedures for making a finding of unacceptable risk, including with respect to how to implement cumulative effects analysis. Such procedures shall be subject to public comment prior to finalization.

(f)The Secretary of Defense is authorized to request and accept a voluntary contribution of funds from an applicant for an energy project or antenna structure project. Amounts so accepted shall remain available until expended for the purpose of offsetting the cost of measures undertaken by the Secretary of Defense to mitigate adverse impacts of such a project on military operations and readiness or to conduct studies of potential measures to mitigate such impacts.

(g)An action taken pursuant to this section shall not be considered to be a substitute for any assessment or determination required of the Secretary of Transportation under section 44718 of title 49.

(h)In this section:

(1)The term “adverse impact on military operations and readiness” means any adverse impact upon military operations and readiness, including flight operations, research, development, testing, and evaluation, and training, that is demonstrable and is likely to impair or degrade the ability of the armed forces to perform their warfighting missions.
