H.R. 2518 would authorize appropriations totaling $19.0 billion over the 2018-2019 period for ongoing activities of the Coast Guard (USCG). Assuming appropriation of the specified amounts, CBO estimates that implementing the legislation would cost $18.3 billion over the 2018-2022 period.
The bill also would authorize the Secretary of Homeland Security to enter into a cooperative agreement with a nonfederal entity to establish, sustain, and operate a system to provide positioning, navigation, and timing (PNT) services as a backup and complement to the existing Global Positioning System (GPS). CBO estimates that enacting that provision would increase net direct spending by $121 million over the 2018-2027 period. Enacting the bill also would affect revenues, but CBO estimates that those changes would be insignificant.
Because enacting the bill would affect direct spending and revenues, pay-as-you-go procedures apply. CBO estimates that enacting H.R. 2518 would not increase net direct spending or on-budget deficits by more than $5 billion in any of the four consecutive 10-year periods beginning in 2028.
H.R. 2518 would impose intergovernmental and private-sector mandates as defined in the Unfunded Mandates Reform Act (UMRA). CBO estimates that the cost of the mandates would fall below the annual thresholds established in UMRA ($78 million for intergovernmental mandates and $156 million for private-sector mandates, respectively, in 2017, adjusted annually for inflation).
