Border Affairs Program

The California Environmental Protection Agency Border Affairs Program promotes interagency cooperation on environmental programs in California and Baja California to help ensure a cleaner, safer, healthier, and more prosperous border region.

The program is a collaborative effort between CalEPA and our Boards, Departments, and Office to address environmental issues on multiple fronts and coordinate efforts with other California state agencies, Baja California, and Tribal Nations in the border region.

The CalEPA Secretary chairs the California Mexico Border Relations Council, which serves as the central organizing body overseeing California-Mexico border issues. It includes the Secretaries of the Environmental Protection Agency, the Health and Human Services Agency, the California Transportation Agency, the Natural Resources Agency, Department of Food and Agriculture, and the Director of the California Office of Emergency Services.


The mission of the CalEPA Border Affairs Program is to work towards a better environment within our shared border by identifying and resolving unique environmental and natural resource challenges, and the resulting public health issues.

This mission is achieved through the use of science and technology, uniform enforcement of environmental laws and regulations, and the cooperation and active participation of the various border communities, California Border Indian Tribal Nations, academia, industry, nongovernmental organizations, and the public.


The Border 2020 U.S.-Mexico Environmental Program is the latest environmental program implemented under the 1983 La Paz Agreement. The Border 2020 Environmental Program, emphasizes regional, bottom-up approaches for decision making, priority setting, and project implementation to address the environmental and public health problems in the border region. The program is designed to encourage meaningful participation from communities and local stakeholders.

Active participation in the California Mexico Border Relations Council (CMBRC) and the U.S.-Mexico Border Environmental Program (Border 2020) is an important element in promoting interagency cooperation and collaboration for CalEPA and its BDOs as well as the member agencies of the CMBRC.
