Congressional Budget Office Cost Estimate: H.R. 1684: Department of Homeland Security Authorization Act for Fiscal Year 2008 [open pdf - 26KB]
"H.R. 1684 would authorize the appropriation of $39.9 billion for fiscal year 2008 to fund operations of the Department of Homeland Security (DHS). The bill also would authorize the appropriation of $456 million over the 2009-2012 period for certain DHS programs. In addition, CBO estimates that the bill would authorize the appropriation of $40 million over the 2009-2012 period for several other programs within DHS. CBO estimates that implementing H.R. 1684 would cost $39.5 billion over the 2008-2012 period, assuming appropriation of the necessary amounts. We estimate that enacting the legislation would increase revenues by $19 million over the 2008-2012 period and $46 million over the 2008-2017 period by allowing Customs and Border Protection officers to increase contributions to their retirement funds. Enacting the bill could affect direct spending, but we estimate that any such effects would not be significant."
