U.S. Customs and Border Protection (CBP) announces the availability of a Final Environmental Assessment (EA) and associated Finding of No Significant Impact (FONSI) for the Proposed Supplemental Air Route Surveillance Radar Unit, South of Mirando City, Webb County, Texas.

The EA documents a review of the potential environmental and socioeconomic effects associated with the construction, operation, and maintenance of a 40-foot tall supplemental air route surveillance radar unit at Site 19 located 5.4 miles west of Farm-to-Market Road 649 and is 4.2 miles southwest of Vaquillas Road. The site is located on a cattle ranch that has also been developed for natural gas production.

A preliminary coordination letter with information about this Proposed Action was sent to Federal, state, and local agencies, as well as local potentially interested parties, to solicit interest or comments concerning this Proposed Action on May 20, 2015. A standard 30-day comment period was provided for comments or communications of interest in this Proposed Action to be submitted. A total of seven (7) comments were received. However, no comments were received that expressed concerns over the possible environmental impacts of the Proposed Action.

In accordance with DHS Instruction Manual 023-01-001-01, Revision 1 guidance concerning the preparation and circulation of EA documents, CBP has determined that the proposed action will not significantly affect the human and natural environments and CBP and is issuing an EA and FONSI and does not need to prepare an Environmental Impact Statement.
