To that end, CBP has prepared an Environmental Stewardship Plan (ESP) for the Naco Station PF225 project (E-2A), which analyzes the potential environmental impacts associated with construction of tactical infrastructure. CBP pursued a comprehensive effort to address potential environmental impacts associated with constructing, maintaining, and operating tactical infrastructure along the Southwest Border. CBP has coordinated with the U.S. Army Corps of Engineers, the U.S. Environmental Protection Agency; U.S. Fish and Wildlife Service; State Historic Preservation Office; and notified applicable Federal, State, Tribal, and local agencies of the project and requested information and input on potential areas of sensitive environmental resources within the project corridor. CBP also consulted with these agencies to identify methods to minimize impacts from the placement and construction of fencing along the southwest border.

In June 2008, CBP posted for public review the project description, examples of vehicle fence, general location of tactical infrastructure, and ESP resource areas for this project to seek information from the public on any sensitive resources that should be included in the preparation of the ESPs. On May 13, 2008, a public meeting was conducted in Sierra Vista to share information on the project and consult with the community on impacts of the project and ways to avoid, minimize, or mitigate adverse impacts. Responses to comments received from these efforts can be viewed below.
