Draft Programmatic EIS
On June 17, 2022, EPA and the U.S. Section of the International Boundary and Water Commission (USIBWC) published a Notice of Availability (NOA) in the Federal Register inviting comments from federal, state, and local agencies, Native American tribes, interested stakeholders and the public on the Draft PEIS. EPA and IBWC held two public meetings on July 19, 2022 and July 20, 2022, with a combined attendance of approximately 100 people. A summary of comments, including those received at the public meetings, and EPA’s response will be available in the Final PEIS. In accordance with NEPA, the Draft PEIS 45-day public comment period concluded on August 1, 2022.

Alternative Options
The Draft Programmatic Environmental Impact Statement (PEIS) evaluates a No-Action Alternative and two alternatives for implementing the Proposed Action. The purpose and need of the Proposed Action is to reduce transboundary flows from Tijuana that convey sewage, pollutants, and/or trash into the U.S. and cause adverse public health and environmental impacts in the Tijuana River watershed and adjacent coastal areas. The projects that are included as part of the two alternatives are in the table below.
- No-Action Alternative. NEPA requires that a No-Action Alternative be analyzed to determine the environmental consequences of not undertaking the Proposed Action, and thereby providing a baseline against which the potential beneficial and adverse environmental impacts of action alternatives can be evaluated and compared.
- Alternative 1: Core Projects. Under this alternative, EPA would use U.S. appropriations to fund some components of the Comprehensive Infrastructure Solution that are the agreed upon responsibility of the U.S. This approach would allow implementation of projects that are sufficiently evolved to be ready for decision making.
- Alternative 2: Core and Supplemental Projects. Under this alternative, EPA would use U.S. appropriations to fund all components of the Comprehensive Infrastructure Solution that are the agreed upon responsibility of the U.S. This approach is expected to require substantial additional U.S. appropriations beyond those already allocated through USMCA Implementation Act and existing programs such as EPA’s Border Water Infrastructure Program (BWIP).
