The Department of Homeland Security (DHS), U.S. Customs and Border Protection (CBP) announces the availability of this Final Environmental Stewardship Plan (ESP). The Secretary of DHS, pursuant to her authority under Section 102(c) of the Illegal Immigration Reform and Immigrant Responsibility Act (IIRIRA), issued a Waiver in January 2018 covering the Tactical Infrastructure (TI) described in this ESP. Although the Secretary’s waiver means that CBP no longer has legal obligation under the laws included in the waiver, the Secretary committed DHS to responsible environmental stewardship of our valuable natural and cultural resources. CBP strongly supports this objective and remains committed to being a good steward of the environment. CBP prepared this ESP to analyze the potential environmental effects associated with constructing, operating, and maintaining TI to include 20 miles of pedestrian wall along the U.S.–Mexico international border within the U.S. Border Patrol’s El Paso Sector, Santa Teresa Station Area of Responsibility. The ESP details the Best Management Practices (BMPs) associated with the TI that CBP will implement during and after construction.
