Atlas Analysis
Verified October 26, 2026 from current EPA FY2027 Region5 Tribal Air webpage and linked 2015 Tribal Air Grants Framework and EPA air grant presentation. CAA105 ALN66.001 is distinct financial assistance track vs CAA103 66.038 and SIRG 66.032. Current controlling announcement cost share 40% standalone; 5% TAS; none within eligible PPG; historic slides discussing subsequent-year increased TAS matches must not override current initial notice, applicants should confirm. No applicant-level cap published; no overall pool substitution. Specific existing grantee placeholder requirement Oct30. Deadline Oct30 2026 6pm CT. Word proposal initial, not SF424. Prior all-status WordPress title search for CAA105/Tribal Air none matching.
EPA Region 5 FY2027 Tribal Air Grants: Clean Air Act Section 105
The U.S. Environmental Protection Agency (EPA) Region 5 Air and Radiation Division invites federally recognized Tribal governments and Tribal consortia in Illinois, Indiana, Michigan, Minnesota, Ohio, and Wisconsin to seek FY2027 financial assistance under Clean Air Act Section 105 (Assistance Listing 66.001). The program supports Tribal implementation of air pollution prevention and control programs and ambient air-quality standards. This is distinct from EPA’s shorter-term Section 103 research/study track.
Applicant funding and required contributions
The funder does not publish a universal individual applicant award maximum. Award amounts depend on EPA review and future funding. The FY2027 announcement states that standalone Section 105 proposals generally require a 40% cost share, reduced to 5% for Tribes approved for Treatment in a Similar Manner as a State under applicable rules. No cost share is required when CAA 105 funding is included in an eligible Performance Partnership Grant (PPG). Applicants should confirm how tribal status and project period affect their applicable rate; do not treat the total EPA program allocation as an individual award.
Eligible activities
Projects may plan, develop, establish, improve, implement and maintain Tribal air-quality management, pollution prevention and control programs, air monitoring, emissions analysis, regulatory infrastructure and related community engagement. Proposed activities must relate to Clean Air Act Section 105 objectives and measurable environmental outputs. Do not request funds to duplicate work covered under another federal award. Qualifying environmental data work requires an EPA-acceptable Quality Assurance Project Plan. Equipment requests are closely reviewed, and unrelated property acquisition, indoor remediation and other activities outside eligible air pollution work are excluded.
Proposal deadline and special rule for existing grantees
Proposals are due October 30, 2026, at 6:00 p.m. Central Time by email to R5ARD_Grants@epa.gov with Word-format materials and subject FY 2027 Tribal Air Funding Announcement Proposal.
