Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF): Budget and Operations for FY2008, FY2009, and FY2010 [April 15, 2010] [open pdf - 238KB]
From the Summary: "The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) is the lead federal law enforcement agency charged with administering and enforcing federal laws related to the manufacture, importation, and distribution of firearms and explosives. Congress transferred ATF's enforcement and regulatory functions for firearms and explosives from the Department of the Treasury to the Department of Justice as part of the Homeland Security Act (P.L. 107-296). ATF is also responsible for investigating arson cases with a federal nexus, as well as criminal violations of federal laws governing the manufacture, importation, and distribution of alcohol and tobacco. For the past two fiscal years, FY2009 and FY2010, Congress has provided ATF with program increases to address illegal gun trafficking from the United States to Mexico under an initiative known as 'Project Gunrunner.' For FY2008, Congress also provided ATF with a program increase for domestic gun trafficking, but the focus of this program increase was also largely on the Southwest border. As a result, for those three fiscal years, Congress has provided over $49 million in program increases to address gun trafficking. Congress has also provided nearly $30 million for the construction of a National Center for Explosives Training and Research (NCETR). In the Consolidated Appropriations Act, 2010 (P.L. 111-117), Congress matched the Administration's request and appropriated $1.121 billion for ATF, or 3.9% more than the agency's FY2009 appropriations ($1.078 billion)."
