Congressional Budget Office Cost Estimate: H.R. 2614: An Act to Amend the Reclamation Wastewater and Groundwater Study and Facilities Act to Authorize the Secretary of the Interior to Participate in Certain Water Projects in California [open pdf - 15KB]
"H.R. 2614 would authorize the Secretary of the Interior to implement two projects to reclaim and reuse groundwater in California. Based on information from the Bureau of Reclamation, CBO estimates that implementing H.R. 2614 would cost $24 million over the 2009-2013 period, assuming appropriation of the necessary amounts. Enacting the legislation would not affect direct spending or revenues. H.R. 2614 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."
