Congressional Budget Office Cost Estimate: S. 518: Small and Rural Community Clean Water Technical Assistance Act [open pdf - 17KB]
"S. 518 would authorize the appropriation of $25 million annually over the 2018-2022 period for the Environmental Protection Agency to provide grants for training and technical assistance to water treatment works owned by public entities that serve communities with populations of fewer than 75,000 individuals. CBO [Congressional Budget Office] estimates that implementing S. 518 would cost $73 million over the next five years, assuming appropriation of the authorized amounts. Enacting the bill would not affect direct spending or revenues; therefore, pay-as-you-go procedures do not apply. CBO estimates that enacting S. 518 would not increase net direct spending or on-budget deficits in any of the four consecutive 10-year periods beginning in 2028. S. 518 contains no intergovernmental or private-sector mandates as defined in the Unfunded Mandates Reform Act (UMRA) and would impose no costs on state, local, or tribal governments."
