Award economics. The award range on file is $5,000 -- $8,000,000. The agency has projected $50.0 million in total estimated funding for this announcement. It expects to issue 25 awards. If the agency funds the expected 25 awards from the $50.0 million estimated pool, the average award works out to roughly $2.0 million. Cost sharing or matching funds are required, meaning applicants must contribute a portion of the project budget from non-federal sources — factor this into your financial plan before drafting the proposal. Federal award ranges are often upper bounds; actual allocations reflect program appropriations, the strength of the applicant pool, and the evaluation committee's scoring.

Deadline and action path. Applications close on September 30, 2026 — roughly 117 days from today. Every Grants.gov submission requires an active SAM.gov registration and a Unique Entity ID. Review the Eligibility section below carefully — federal eligibility categories (nonprofit, state or local government, tribal, individual, educational institution, small business) have distinct registration and reporting requirements. Pre-application outreach to the listed agency contact is permitted and often welcomed — it helps clarify scope and scoring priorities.
