This bill, titled the CONTAINER Act , empowers states adjacent to the northern or southern international borders to deploy movable, temporary structures on certain federal lands to enhance border security. It specifically exempts these Border States from needing a special use authorization from federal land management agencies, such as the Bureau of Land Management or the Forest Service, provided they submit a 45-day advance notice of the proposed placement. These temporary structures are initially permitted for a period of one year. However, their placement can be extended in 90-day increments, subject to approval by the relevant Secretary (Interior or Agriculture). Such extensions require consultation with the Commissioner of U.S. Customs and Border Protection and *must* be approved if the Commissioner determines that operational control of the border has not yet been achieved.
