This bill expands eligibility for the Defense Community Infrastructure Program (DCIP) by including Indian tribes as eligible applicants. The primary purpose is to allow tribal governments to receive federal funding for infrastructure projects that benefit military installations and the communities surrounding them, fostering stronger partnerships and improving essential services. Specifically, the legislation amends Section 2391 of title 10, United States Code, to explicitly add "Indian tribes" alongside state and local governments in provisions related to program eligibility and application processes. It also incorporates a definition for "Indian tribe" by referencing the Indian Self-Determination and Education Assistance Act, ensuring clarity on which entities qualify for this expanded opportunity.
