A letter report issued by the Government Accountability Office with an abstract that begins "Many TARP programs continue to be in various stages of unwinding and some programs, notably those that focus on the foreclosure crisis, remain active. The figure provides an overview of selected programs and the amount disbursed and outstanding, as applicable. Treasury has articulated broad principles for exiting TARP, including exiting TARP programs as soon as practicable and seeking to maximize taxpayer returns, goals that at times conflict. Some of the programs that Treasury continues to unwind, such as investments in American International Group, Inc. (AIG), require Treasury to actively manage the timing of its exit as it balances its competing goals. For other programs, such as the Capital Purchase Program (CPP)—which was created to provide capital to financial institutions—Treasury’s exit will be driven primarily by the financial condition of the participating institutions. Consequently, the timing of Treasury’s exit from TARP remains uncertain."

Correspondence issued by the Government Accountability Office with an abstract that begins "The Consolidated Appropriations Act, 2012, amended the Clean Air Act to transfer regulatory authority for air emissions on the outer continental shelf (OCS) off Alaska's north coast, including the Chukchi and Beaufort seas, from the Environmental Protection Agency (EPA) to the Department of the Interior. Since the act was passed on December 23, 2011, there has been limited activity subject to air emission regulations or permitting on the OCS off Alaska's north coast, according to officials at the EPA and Interior. EPA officials stated that, before the act was passed, EPA had issued to Shell Gulf of Mexico Inc. and Shell Offshore, Inc., collectively, three air emission permits for drilling and other activities on the OCS off Alaska's north coast. Interior's Bureau of Ocean Energy Management (BOEM) is responsible for reviewing and approving plans for exploration, development, and production activities; this process includes projections of air emissions. According to a BOEM official, after the act passed, Shell conducted exploratory drilling on the OCS off Alaska's north coast in 2012, but it did so under its existing air emissions permits from EPA. Ancillary activities, such as surveys of the …

A letter report issued by the Government Accountability Office with an abstract that begins "A significant amount of water is produced daily as a byproduct from drilling of oil and gas. A 2009 Argonne National Laboratory study estimated that 56 million barrels of water are produced onshore every day, but this study may underestimate the current total volume because it is based on limited, and in some cases, incomplete data generated by the states. In general, the volume of produced water generated by a given well varies widely according to three key factors: the hydrocarbon being produced, the geographic location of the well, and the method of production used. For example, some gas wells typically generate large volumes of water early in production, whereas oil wells typically generate less. Generally, the quality of produced water from oil and gas production is poor, and it cannot be readily used for another purpose without prior treatment. The specific quality of water produced by a given well, however, can vary widely according to the same three factors that impact volume—hydrocarbon, geography, and production method."

A letter report issued by the Government Accountability Office with an abstract that begins "The Environmental Protection Agency (EPA) has implemented all of the recommendations GAO made in its May 2011 report to improve the Unregulated Contaminant Monitoring Rule (UCMR) program. In that report, GAO recommended that EPA (1) monitor for the full 30 contaminants allowed by statute, (2) monitor for most or all contaminants using a more robust monitoring approach, and (3) select sufficiently sensitive minimum reporting levels (MRL) for monitoring contaminants. EPA now requires public water systems to monitor for 30 contaminants in the UCMR3 program, using its most robust monitoring approach for a majority of these contaminants, and setting MRLs as low as can be reliably measured, according to EPA. The Safe Drinking Water Act (SDWA) requires EPA to vary the monitoring frequency based on the type of contaminant likely to be found, but EPA used a standard monitoring frequency for all contaminants. This may result in inaccurate estimates of the occurrence of sporadically occurring microbes (e.g., viruses) or pesticides, according to experts GAO surveyed and studies it reviewed. In such cases, the monitoring data may not provide reliable estimates of contaminant occurrence."
