From the Summary: "CBO [Congressional Budget Office] estimates that implementing this legislation would cost $86 million over the 2007-2012 period, assuming appropriation of the authorized amount. H.R. 700 would authorize an Environmental Protection Agency program to provide grants to states, interstate and intrastate water resource development agencies, local government agencies, private utilities, and nonprofit entities to develop projects that would enhance water supplies by reusing or treating wastewater. This legislation would authorize the appropriation of $125 million for a pilot program without any fiscal-year limitation. Enacting the bill would not affect direct spending or revenues. H.R. 700 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."
