DoD Siting Clearinghouse Reviews

Mission Compatibility Evaluation Process

The DoD has a structured process for developers to request a mission compatibility evaluation of a proposed energy project, as documented in Part 211 of Title 32 CFR.

Some states have incorporated notifying DoD about proposed energy projects into their requirements. The Electrical Reliability Council of Texas (ERCOT) is one example. PGRR047 FIS Department of Defense Declaration, passed in 2016, requires entities to notify the DoD Siting Clearinghouse of a proposed energy project and request an informal or formal review before submitting to ERCOT for a full interconnection study (FIS).

Formal Review

The DoD Siting Clearinghouse formal review process applies to projects filed with the Secretary of Transportation, under Title 49 U.S.C., Section 44718 (Federal Aviation Administration obstruction evaluation process) and addresses all energy projects greater than 199 feet above ground level, proposed for construction within military training routes or special use airspace, whether on private, state, or Federal property, such as the Bureau of Land Management lands.

Informal Review

The DoD Siting Clearinghouse encourages all energy proponents to seek informal reviews as early as possible to identify potential compatibility concerns. Developers of an energy project; a landowner; a State, Indian tribal, or local official; or other Federal agency should request a preliminary determination from the DoD Siting Clearinghouse in advance of filing an application with the Secretary of Transportation under Title 49 U.S.C., Section 44718 or where a preliminary DoD determination is desired.

If the request for an informal review includes information that is proprietary or competition sensitive, we encourage that the documents be marked accordingly. Documents must be marked as "Proprietary" or "Business Sensitive" to ensure they are properly safeguarded upon receipt. Do not mark documents as "Confidential," as that can be easily mistaken for a national security classification. Properly marked proprietary information will be protected under exemption to the Freedom of Information Act and will only be used to assess potential impacts on military missions.
