Water Pollution Control State, Interstate, and Tribal Program Support is sponsored by ENVIRONMENTAL PROTECTION AGENCY. To assist States (including territories and the District of Columbia), Indian Tribes qualified under CWA Section 518(e), and interstate agencies in establishing and maintaining adequate measures for prevention and control of surface and ground water pollution from both point and nonpoint sources.
States and Tribes will continue to focus on fulfilling their basic responsibilities under the CWA Section 106 funded programs, such as: (1) implementing monitoring strategies and the statistically-valid surveys to determine water quality status and trends; (2) fostering a watershed approach, including total maximum daily loads (TMDLs) and watershed plans designed to meet water quality standards; (3) implementing National Pollutant Discharge Elimination System (NPDES) permitting programs; and 4) States and Tribes will continue adopting updated water quality standards that support designated uses and completing triennial reviews on time. States NPDES Programs will continue to: (1) ensure the integrity of the program; (2) achieve and measure environmental results; and (3) incorporate efficiencies in permitting program operations. States will also conduct source water protection actions to protect both ground water and surface waters used for drinking water. Tribes will continue to conduct watershed assessments and will maintain and improve their capacity to implement water quality programs through monitoring, assessments, planning, data management and standards development.

On June 29, 2026, EPA announced it will waive the $25,000 WIFIA application fee and the credit processing fee — averaging roughly $156,000 per loan — for communities of 25,000 or fewer residents in fiscal years 2026 and 2027. Combined, that removes nearly $200,000 in upfront cost from the single most affordable federal water-infrastructure financing program, which carries roughly $11 billion in available capacity and can cover up to 80% of eligible project costs at Treasury-rate pricing. For small towns, rural utilities, and the nonprofits and districts that serve them, this is a rare instance of the federal government lowering the barrier to a program that has historically been out of reach for exactly the communities that need it most. Here is what changed, who qualifies, and how to move on a letter of interest before the window closes.
Read articleFor FY2026 and FY2027, EPA is waiving the $25,000 WIFIA application fee and the ~$156,000 credit-processing fee for water systems serving 25,000 or fewer people — a near-$200,000 discount on access to an $11 billion pool of low-cost federal financing. The waiver removes the single barrier that kept small and rural utilities out of WIFIA for a decade. Here is how WIFIA actually works, who qualifies, why the letter of interest is the real gate, and how a town of 8,000 should think about a program built for billion-dollar projects.
Read articleFor FY2026 and FY2027, EPA is waiving the WIFIA application and credit-processing fees for communities of 25,000 or fewer — saving nearly $200,000 per loan — against roughly $11 billion in flexible financing that covers up to 80 percent of project costs. Here is why WIFIA has been underused by small systems, how the loan actually works, and how a rural utility should build a WIFIA strategy in 2026.
