SBIR Phase I — EPA
U.S. Environmental Protection Agency
Up to $100K (Phase I)
EPA seed fund for environmental tech R&D
EPA SBIR Phase I awards up to $100,000 for 6 months of environmental technology R&D — water treatment, air quality, sustainable materials, pollution monitoring, climate adaptation, and waste reduction. The smallest per-award SBIR among major agencies, but EPA's focus areas are highly specific and underfunded elsewhere. One to two annual solicitations with narrowly defined topic areas. Non-dilutive federal grant submitted via Grants.gov. EPA Phase I frequently co-occurs with Phase II applications, compressing the development timeline. NOTE: The SBIR/STTR reauthorization lapsed October 1, 2025 and was restored April 13, 2026 with reauthorization through September 30, 2031. The 2026 reauthorization added a mandatory foreign national screening requirement for all applicants.

How to apply
-
1
Register in SAM.gov, SBIR Company Registry, and Grants.gov
Complete three registrations: SAM.gov (UEI — allow 2–3 weeks for new entities), SBA SBIR Company Registry at sbir.gov, and a Grants.gov applicant account. EPA SBIR uses Grants.gov Workspace for submission. Confirm your SAM.gov registration is active and your Grants.gov account is linked to your organization's profile before the deadline.

Read the EPA SBIR solicitation and identify your topic
EPA SBIR topics are organized around EPA program offices: Office of Water, Office of Air and Radiation, Office of Land and Emergency Management, Office of Pesticide Programs, Office of Research and Development, and others. Topics are specific — not broad environmental themes. Email the EPA topic contact listed in the solicitation to confirm fit before writing. EPA Program Officers are accessible and responsive to pre-submission inquiries.

Write the 6-page technical proposal and commercialization plan
EPA Phase I proposals are concise — Phase I Technical Volume is typically 6 pages. Cover: (1) the technical objective and hypothesis, (2) the Phase I approach and feasibility methodology, (3) expected Phase I outcomes and go/no-go criteria, and (4) the path from Phase I to Phase II to commercialization. The $100,000 / 6-month budget requires a sharply focused feasibility objective — reviewers expect you to demonstrate a proof-of-concept, not develop a finished product.

Submit via Grants.gov Workspace
Assemble and submit the complete application package through Grants.gov Workspace before 11:59 PM Eastern on the published deadline. Allow 2–3 business days before the deadline for error resolution. Confirm receipt of a valid submission confirmation from Grants.gov.

Technical review and award notification
EPA conducts peer review using scientists from EPA's Office of Research and Development and external environmental technology experts. Award notifications typically arrive 4–6 months after the proposal deadline. EPA Phase I performance periods are 6 months from the award start date.

EPA's $100K cap is the lowest among major SBIR agencies — design a Phase I feasibility study that is genuinely completable in 6 months and $100K. Don't underestimate the advantage: competition is lower, topic areas are underserved by private capital, and successful EPA Phase I → Phase II → commercialization companies (e.g., water treatment tech firms) have built defensible market positions with a non-dilutive foundation.
Deadline & timing
EPA SBIR has historically run one to two solicitation cycles per fiscal year with topic areas varying by cycle. EPA Phase I is 6 months and Phase II is 24 months. EPA's SBIR program has experienced variability in annual solicitation release — in some years EPA has skipped a cycle or combined Phase I and Phase II submissions. Always check epa.gov/sbir directly for the most current solicitation schedule.
