This legislation aims to enhance counter-narcotics detection by requiring the Secretary of Homeland Security, through U.S. Customs and Border Protection (CBP), to deploy advanced screening technology at vulnerable border crossings. It mandates an annual process to identify high-risk land ports of entry based on their drug seizure volumes, specifically those at or above the 70th percentile for either the northern or southern border. Within one year of identifying such a port, CBP must implement large-scale, non-intrusive inspection (NII) technology for cargo screening, unless deemed ineffective by established criteria. Following the implementation of NII technology, the bill requires its use to screen a significant percentage of vehicles. Specifically, it mandates screening not less than 40 percent of feasible passenger vehicles and not less than 70 percent of feasible commercial vehicles entering through these high-risk ports. Furthermore, the Commissioner must ensure relevant CBP personnel receive comprehensive training on the new NII systems and annually seek to identify new technologies that could further improve cargo screening capabilities. Regular reports detailing the technology's effectiveness and any newly identified systems must be submitted to Congress.
