Joint Task Force Six (JTF-6) in cooperation with the United States Army Corps of Engineers (USCOE), Fort Worth District, has completed a series of five Technical Support Documents to define the baseline environmental conditions along the Texas Gulf Coast and the United States/Mexico International Land Border. The information in the Technical Support Documents will be used to develop a Programmatic Environmental Impact Statement (EIS) to assess potential and cumulative environmental impacts on proposed JTF-6 activities in these areas. The mission of JTF-6 is to plan and coordinate military operations and training along the Texas Gulf Coast and the U.S. southwest land border from Texas to California in support of counter-narcotics activities by federal, state, and local law enforcement agencies.
