To amend the Tijuana River Valley Estuary and Beach Sewage Cleanup Act of 2000 to extend the authorization of appropriations, and for other purposes.

This law addresses long-standing sewage pollution issues in the Tijuana River Valley by authorizing the United States to work with Mexico to build and operate a wastewater treatment plant in Mexico. It prioritizes the creation of a facility to provide secondary treatment for sewage that frequently flows across the border, contaminating beaches and estuaries in Southern California.

For citizens, this measure is designed to improve public health and coastal water quality by reducing the amount of untreated waste reaching U.S. shores. By streamlining the contracting process and extending funding for these cleanup efforts, the law aims to provide a more permanent solution to cross-border environmental hazards and keep local beaches open and safe for recreation.
