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 11, 2026, U.S. District Judge Richard Gergel ruled that the EPA's February 2025 termination of the $2.8 billion Environmental and Climate Justice Block Grant Program — created by Section 60201 of the Inflation Reduction Act — was arbitrary, capricious, and unlawful. The ruling voids the termination but does not order the EPA to resume the program, leaving the September 30, 2026 statutory deadline as the binding constraint. For the 116 grantees and the coalition of nonprofits, cities, and tribal partners that were already in award negotiations, the next 105 days will determine whether the program survives in any operational form or migrates entirely to the Court of Federal Claims as a damages action.
