About this program

The Environmental Protection Agency funds water quality management planning for states, territories, the District of Columbia, regional public comprehensive planning organizations, and interstate organizations through Assistance Listing 66.454, with the most recent grant award disbursed in January 2026.

The program funds concrete planning activities that support Clean Water Act implementation: developing and revising water quality standards, identifying and assessing impaired waterbodies, developing total maximum daily loads (TMDLs) and restoration or protection plans, conducting water quality monitoring and ambient data collection, performing watershed assessments, developing watershed-based plans, coordinating with stakeholders on restoration efforts, and supporting regional planning agency operations. Recent awards show applicants pursuing monitoring for emerging contaminants including PFAS and cyanotoxins, developing nutrient reduction strategies, assessing climate and equity impacts to water quality, and building databases and tools for water quality tracking and assessment.

The program is overwhelmingly Formula Grant–based, with 1,177 awards of 1,377 total (85 percent), complemented by 179 Project Grants (13 percent) and 21 Cooperative Agreements (2 percent). The Environmental Protection Agency dominates funding across all regional offices, awarding 1,060 grants totaling $275.5 million in federal dollars obligated. EPA Region 5, Region 2, and Region 3 follow as secondary funders, collectively accounting for $97.3 million.

The program has distributed $462.2 million in federal dollars across 1,377 awards since 1994. Typical award magnitudes range from approximately $150 thousand to $2 million, though California received $3.08 million (January 2026) and New York received $4.753 million (April 2025). The combined federal and non-federal share across all awards totals $477.3 million, indicating modest recipient cost-share requirements. Award cadence has remained steady at 39–44 awards annually over the past five years, with only 2 awards year-to-date in 2026 as of the portfolio snapshot.

Recent representative awards include Pennsylvania's $1.556 million grant (January 2026) for water quality management planning including algal toxin data collection and advanced restoration plan development; Oklahoma's $347 thousand award (January 2026) supporting well water testing and groundwater modeling; and Illinois's $1.947 million grant (October 2025) for characterization of waterbodies and watershed-based plan development. Grant opportunities are not currently posted in available sources; applicants should contact EPA regional offices for application deadlines, which typically allow approximately 45 days for submission.

EPA may approve a State's request to pass through less than 40 percent if, after consultation with its RPCPOs and IOs, the Governor determines that pass through of at least 40 percent will not: (1) result in significant participation by RPCPOs and IOs in WQM planning; and (2) significantly assist in development and implementation of the state's WQM plan.
