The Congressional Record is the official record of the proceedings and debates of the United States Congress. It is published daily when Congress is in session. The Congressional Record began publication in 1873. Debates for sessions prior to 1873 are recorded in The Debates and Proceedings in the Congress of the United States (1789-1824), the Register of Debates in Congress (1824-1837), and the Congressional Globe (1833-1873)

"The United States Code is the official codification of the general and permanent laws of the United States of America. The Code was first published in 1926, and a new edition of the code has been published every six years since 1934. The 2012 edition of the Code incorporates laws enacted through the One Hundred Twelfth Congress, Second Session, the last of which was signed by the President on January 15, 2013. It does not include laws of the One Hundred Thirteenth Congress, First Session, enacted between January 2, 2013, the date it convened, and January 15, 2013. By statutory authority this edition may be cited "U.S.C. 2012 ed." As adopted in 1926, the Code established prima facie the general and permanent laws of the United States. The underlying statutes reprinted in the Code remained in effect and controlled over the Code in case of any discrepancy. In 1947, Congress began enacting individual titles of the Code into positive law. When a title is enacted into positive law, the underlying statutes are repealed and the title then becomes legal evidence of the law. Currently, 26 of the 51 titles in the Code have been so enacted. These are identified in the table of titles near the beginning of each volume. The Law Revision Counsel of the House of Representatives continues to prepare legislation pursuant to 2 U.S.C. 285b to enact the remainder of the Code, on a title-by-title basis, into positive law. The 2012 edition of the Code was prepared and published under the supervision of Ralph V. Seep, Law Revision Counsel. Grateful acknowledgment is made of the contributions by all who helped in this work, particularly the staffs of the Office of the Law Revision Counsel and the Government Printing Office"--Preface.

Across the United States, thousands of hazardous waste sites are contaminated with chemicals that prevent the underlying groundwater from meeting drinking water standards. These include Superfund sites and other facilities that handle and dispose of hazardous waste, active and inactive dry cleaners, and leaking underground storage tanks; many are at federal facilities such as military installations. While many sites have been closed over the past 30 years through cleanup programs run by the U.S. Department of Defense, the U.S. EPA, and other state and federal agencies, the remaining caseload is much more difficult to address because the nature of the contamination and subsurface conditions make it difficult to achieve drinking water standards in the affected groundwater. Alternatives for Managing the Nation's Complex Contaminated Groundwater Sites estimates that at least 126,000 sites across the U.S. still have contaminated groundwater, and their closure is expected to cost at least $110 billion to $127 billion. About 10 percent of these sites are considered "complex," meaning restoration is unlikely to be achieved in the next 50 to 100 years due to technological limitations. At sites where contaminant concentrations have plateaued at levels above cleanup goals despite active efforts, the report recommends evaluating whether the sites should transition to long-term management, where risks would be monitored and harmful exposures prevented, but at reduced costs.

Congress has continued to debate the efficacy and constitutionality of federal regulation of firearms and ammunition, with strong advocates arguing for and against greater gun control. While several dozen gun control-related proposals have been introduced in recent Congresses, only a handful of those bills received significant legislative action. The 109th Congress, for example, passed two bills with firearmsrelated provisions that were enacted into law. P.L. 109-72 prohibits certain types of lawsuits against firearm manufacturers and dealers to recover damages related to the criminal or unlawful use of their products by other persons, and P.L. 109-295 includes a provision that prohibits federal officials from seizing any firearm from private persons during a major disaster or emergency, if possession of that firearm was not already prohibited under federal or state law. Nevertheless, the 110th Congress could possibly reconsider several gun control proposals that were considered as part of appropriations and crime legislation in the previous Congress. During the 109th Congress, the House amended the Children's Safety Act of 2005 (H.R. 3132) to prohibit the transfer or possession of a firearm to or by any person convicted of a sex offense against a minor. The House also amended Secure Access to Justice and Court Protection Act of 2005 (H.R. 1751) to authorize certain federal court judges and officials to carry firearms for personal protection. The Senate passed a different version of H.R. 1751 that included similar provisions, as well as provisions designed to clarify and expand the Law Enforcement Officers Safety Act (P.L. 108-277) -- a law that gives concealed carry privileges to qualified on-duty and retired law enforcement officers. None of those provisions were enacted into law, however. In addition, the House Judiciary considered four gun-related bills: the ATFE Modernization and Reform Act of 2006 (H.R. 5092), the Firearms Corrections and Improvement Act (H.R. 5005), the Firearm Commerce Modernization Act (H.R. 1384), and the NICS Improvement Act of 2005 (H.R. 1415). H.R. 5092 was passed by the House. The 109th Congress, moreover, maintained a fee prohibition for Brady background checks and other funding limitations and conditions related to gun enforcement in the FY2006 DOJ appropriations (P.L. 109-108). Those limitations and conditions have been continued into FY2007 under continuing resolutions. They are often referred to as the "Tiahrt amendment," for their sponsor in the FY2004 appropriations cycle, Representative Todd Tiahrt. Issues addressed in those bills, as well as the Tiahrt funding limitations and conditions, could be reconsidered in the 110th Congress. Senator Charles Schumer, for example, has introduced a bill (S. 77) that would repeal portions of the Tiahrt amendment that limit the sharing of firearm trace data. Other gun control-related issues that may reemerge in the 110th Congress include (1) retaining Brady background check records for approved transactions to enhance terrorist screening, (2) more strictly regulating certain long-range fifty caliber rifles, (3) further regulating certain firearms previously defined in statute as "assault weapons," and (4) requiring background checks for firearm transfers at gun shows. This report will updated to reflect legislative action.
