Congressional Budget Office Cost Estimate: S. 1280, Coast Guard Authorization Act of 2005 [open pdf - 20KB]
From the Summary: "S. 1280 would authorize appropriations for U.S. Coast Guard (USCG) activities for fiscal years 2006 and 2007. CBO [Congressional Budget Office] estimates that appropriation of the authorized amounts would result in outlays of $4.7 billion in fiscal year 2006 and $14.6 billion over the 2006-2010 period. (About $500 million of the authorized amounts would be spent after 2010.) Enacting S. 1280 would have no effect on direct spending. Because the bill would raise existing civil penalties for violations of the Maritime Transportation Security Act, its enactment could affect revenues, but we expect that any resulting increases would be less than $500,000 annually."
