Projects to Prevent or Reduce Nonpoint Source Pollution in Texas Waterways

Information about projects funded under the Clean Water Act Section 319(h) Nonpoint Source Pollution Grant

What is a Nonpoint Source Pollution (NPS) Project?

TCEQ’s NPS Program administers projects that prevent or reduce nonpoint source pollution using funds awarded by the U.S. Environmental Protection Agency (EPA) under Section 319(h) of the federal Clean Water Act (CWA). These grant-funded projects operate within a limited time period and must address the objectives, goals, and/or priorities identified in the most recent Texas NPS Management Program.

How Are NPS Projects Awarded and Funded?

EPA awards CWA Section 319(h) grant funds annually to TCEQ and to the Texas State Soil and Water Conservation Board (for agricultural and silvicultural projects only). TCEQ uses most of the funds to partially reimburse the cost of projects performed by sub-grantees. Sub-grantees may be state agencies, local governments, other subdivisions of the state, or nonprofit organizations. TCEQ awards 319(h) grant funds through a competitive application process. Visit TCEQ's NPS Grant Program page for more information about how to apply for funds, eligibility, and funding priorities.

List of NPS Implementation Projects

The following list, organized by project status and watershed, contains links to individual implementation project webpages, which provide location, background information, and details about project activities. Watersheds with multiple implementation projects have a single webpage describing all projects.

Information about watershed protection plan (WPP) development projects can be found at the NPS WPP webpage.
