A letter report issued by the Government Accountability Office with an abstract that begins "U. S. aquaculture--the raising of fish and shellfish in captivity--has generally been confined to nearshore coastal waters or in other water bodies, such as ponds, that fall under state regulation. Recently, there has been an increased interest in expanding aquaculture to offshore waters, which would involve raising fish and shellfish in the open ocean, and consequently bringing these types of operations under federal regulation. While the offshore expansion has the potential to increase U.S. aquaculture production, no comprehensive legislative or regulatory framework to manage such an expansion exists. Instead, multiple federal agencies have authority to regulate different aspects of offshore aquaculture under a variety of existing laws that were not designed for this purpose. In this context, GAO was asked to identify key issues that should be addressed in the development of an effective regulatory framework for U.S. offshore aquaculture. In conducting its assessment, GAO administered a questionnaire to a wide variety of key aquaculture stakeholders; analyzed laws, regulations, and key studies; and visited states that regulate nearshore aquaculture industries. Although GAO is not making any recommendations, this review emphasizes the need to carefully consider a …

A letter report issued by the Government Accountability Office with an abstract that begins "Elevated levels of greenhouse gases in the atmosphere and the resulting effects on the earth's climate could have significant environmental and economic impacts in the United States and internationally. Potential impacts include rising sea levels and a shift in the intensity and frequency of floods and storms. Proposed responses to climate change include adapting to the possible impacts by planning and improving protective infrastructure, and reducing greenhouse gas emissions directly through regulation or the promotion of low-emissions technologies. Because most U.S. emissions stem from the combustion of fossil fuels such as coal, oil, and natural gas, much of this report centers on the effect emissions regulation could have on the economy. In this context, GAO was asked to elicit the opinions of experts on (1) actions the Congress might consider to address climate change and what is known about the potential benefits, costs, and uncertainties of these actions and (2) the key strengths and limitations of policies or actions to address climate change. GAO worked with the National Academy of Sciences to identify a panel of noted economists with expertise in analyzing the economic impacts of …

A letter report issued by the Government Accountability Office with an abstract that begins "GAO reports since 1998 have demonstrated that state surveyors, who evaluate the quality of nursing home care on behalf of CMS, sometimes understate the extent of serious care problems in homes because they miss deficiencies. CMS oversees the effectiveness of state surveys through the federal monitoring survey program. In this program, federal surveyors in CMS's regional offices either independently evaluate state surveys by resurveying a home (comparative surveys) or directly observe state surveyors during a routine nursing home survey (observational surveys). GAO was asked to evaluate the information federal monitoring surveys provide on understatement and the effectiveness of CMS management and oversight of the survey program. To do this, GAO analyzed the results of federal monitoring surveys for fiscal years 2002 through 2007, reviewed CMS guidance for the survey program, and interviewed headquarters and regional office officials."

A letter report issued by the Government Accountability Office with an abstract that begins "Unreliable real property data has been a long-standing problem for federal landholding agencies. Under the President's real property initiative, agencies are being held accountable for, among other things, improving accuracy of their real property inventory and disposing of unneeded property. The U.S. Army Corps of Engineers (Corps), the fourth largest landholding agency, uses the Real Estate Management Information System (REMIS) for recording its civil works inventory. GAO was asked to determine whether REMIS could provide reliable information on the Corps' civil works land disposals from fiscal years 1996 through 2006. GAO's work involved comparison analyses of REMIS disposal data and other Corps reported disposal data, reviews of Corps' real property policies and guidance, and interviews with Corps officials at headquarters, three divisions, four districts, and the Real Estate Systems National Center (RESNC), which manages REMIS."

A study of the impact of neptunium on the coulometric assay of plutonium in dilute sulfuric acid was performed. Weight aliquots of plutonium standard solutions were spiked with purified neptunium solution to evaluate plutonium measurement performance for aliquots with Pu:Np ratios of 50:1, 30:1, 20:1, 15:1, and 10:1. Weight aliquots of the pure plutonium standard solution were measured as controls. Routine plutonium instrument control standards were also measured. The presence of neptunium in plutonium aliquots significantly increases the random uncertainty associated with the plutonium coulometric measurement performed in accordance with ISO12183:2005.7 However, the presence of neptunium does not appear to degrade electrode performance and conditioning as aliquots of pure plutonium that were interspersed during the measurement of the mixed Pu:Np aliquots continued to achieve the historical short-term random uncertainty for the method. Lack of adequate control of the neptunium oxidation state is suspected to be the primary cause of the elevated measurement uncertainty and will be pursued in a future study.

The ocean and atmosphere are both governed by the same physical laws and models of the two media have many similarities. However, there are critical differences that call for special methods to provide the best simulation. One of the most important difference is that the ocean is nearly opaque to radiation in the visible and infra-red part of the spectrum. For this reason water mass properties in the ocean are conserved along trajectories for long distances and for long periods of time. For this reason isopycnal coordinate models would seem to have a distinct advantage in simulating ocean circulation. In such a model the coordinate surfaces are aligned with the natural paths of near adiabatic, density conserving flow in the main thermocline. The difficulty with this approach is at the upper and lower boundaries of the ocean, which in general do not coincide with density surfaces. For this reason hybrid coordinate models were proposed by Bleck and Boudra (1981) in which Cartesian coordinates were used near the ocean surface and isopycnal coordinates were used in the main thermocline. This feature is now part of the HICOM model (Bleck, 2002).

Under a contract with CH2M Hill Hanford Group, Inc., PNNL has performed a review of the NDE technology and methods for examination of the concrete dome structure of Hanford’s double-shell tanks. The objective was to provide a matrix of methodologies that could be evaluated based on applicability, ease of deployment, and results that could provide information that could be used in the ongoing structural analysis of the tank dome. PNNL performed a technology evaluation with the objective of providing a critical literature review for all applicable technologies based on constraints provided by CH2M HILL. These constraints were not mandatory, but were desired. These constraints included performing the evaluation without removing any soil from the top of the tank, or if necessary, requesting that the hole diameter needed to gain access to evaluate the top of the tank structure to be no greater than approximately 12-in. in diameter. PNNL did not address the details of statistical sampling requirements as they depend on an unspecified risk tolerance. PNNL considered these during the technology evaluation and have reported the results in the remainder of this document. Many of the basic approaches to concrete inspection that were reviewed in previous efforts are still in …
