EPA's Innovative Water Infrastructure Workforce Development competition closes October 5, 2026. The agency says up to 15 awards across four project areas, but Project Area 1 alone carries a $7.8 million ceiling against a $10.8 million pot. That tension is the single most important strategic fact in the NOFO — here is how to read it, which lane is least competed, and what a three-week runway means for your submission.
Read articleEPA announced $3.5 million in competitive Clean Water Act Section 319 funding for Tribes on September 10, 2026, with a $175,000 per-applicant cap and roughly 20 awards. Applications close November 9, 2026. But eligibility was frozen as of October 10, 2025, and every application must contain an on-the-ground BMP project traceable to an approved management program. Here is how the gates actually work.
Read articleThe FY2026 Innovative Water Infrastructure Workforce Development Grant (EPA-OW-OWM-26-03) closes October 5, 2026 with $10.8 million, up to 15 cooperative agreements, and a Project Area 1 ceiling of $7.8 million. One maximum award would consume 72 percent of the pool. Here is how the four project areas actually partition the money, why the grants.gov award floor field is wrong, and why September 14 is the date that matters more than October 5.
