Congressional Budget Office Cost Estimate: H.R. 6083, Federal Agriculture Reform and Risk Management Act of 2012 [open pdf - 113KB]
From the Summary: "H.R. 6083 would amend and extend a number of major programs administered by the U.S. Department of Agriculture (USDA), including those addressing farm income support, food and nutrition, land conservation, trade promotion, rural development, research, forestry, energy, horticulture, and crop insurance. When combined with estimated spending under CBO's [Congressional Budget Office] baseline projections for those programs, CBO estimates that enacting the Federal Agriculture Reform and Risk Management Act of 2012 would bring total direct spending for those USDA programs to $957.7 billion over the 2013-2022 period--$35.1 billion less than we project would be spent if those programs were continued as under current law."
