"S. [Senate Bill] 3525 would allow the Department of the Interior to raise the price charged for Federal Migratory Bird Hunting and Conservation Stamps (referred to as federal duck stamps). CBO [Congressional Budget Office] estimates that enacting this provision would increase revenues and associated direct spending by $132 million over the 2013-2022 period. The bill also would reauthorize the Federal Land Transaction Facilitation Act (FLTFA) to allow certain federal agencies to spend, without further appropriation, proceeds from the sale of land administered by the Bureau of Land Management (BLM) to purchase inholdings (privately held land surrounded by federal land). Based on information provided by BLM, CBO estimates that enacting this provision would increase both the proceeds from sale of federal property and the spending of sale proceeds. On balance, CBO estimates that enacting this provision would yield a small net reduction in direct spending of $5 million over the 2013-2022 period--primarily because the spending of sale proceeds would lag behind such collections over the next 10 years. In total, CBO estimates that enacting S. 3525 would reduce the deficit by $5 million over the 2013-2022 period."
