The Department of Homeland Security (DHS) is responsible for ensuring the security of the nation’s transportation systems, particularly at points of entry into the United States by air, land, and sea. S. 763 would authorize appropriations totaling $2.5 billion for grants to enhance the security of surface and maritime transportation systems and the bill also would require DHS to pursue a range of activities aimed at identifying and addressing the vulnerabilities of such systems. Assuming appropriation of the estimated and authorized amounts, CBO estimates that implementing S. 763 would cost $1.3 billion over the 2018-2022 period, and an additional $1.2 billion after 2022.
Enacting the bill would not affect direct spending or revenues; therefore, pay-as-you-go procedures do not apply. CBO estimates that enacting S. 763 would not increase net direct spending or on-budget deficits in any of the four consecutive 10-year periods beginning in 2028.
S. 763 contains no intergovernmental or private-sector mandates as defined in the Unfunded Mandates Reform Act and would impose no costs on state, local, or tribal governments.
