Acoustical Imaging and Mechanical Properties of Soft Rock and Marine Sediments Progress Report: October-December 2001
During this phase of the project the research team concentrated on acquisition of acoustic emission data from the high porosity rock samples. The initial experiments indicated that the acoustic emission activity from high porosity Danian chalk were of a very low amplitude. Even though the sample underwent yielding and significant plastic deformation the sample did not generate significant AE activity. This was somewhat surprising. These initial results call into question the validity of attempting to locate AE activity in this weak rock type. As a result the testing program was slightly altered to include measuring the acoustic emission activity from many of the rock types listed in the research program. The preliminary experimental results indicate that AE activity in the sandstones is much higher than in the carbonate rocks (i.e., the chalks and limestones). This observation may be particularly important for planning microseismic imaging of reservoir rocks in the field environment. The preliminary results suggest that microseismic imaging of reservoir rock from acoustic emission activity generated from matrix deformation (during compaction and subsidence) would be extremely difficult to accomplish.

Customs Service: Effects of Proposed Legislation on Officers' Pay
A letter report issued by the General Accounting Office with an abstract that begins "GAO reviewed the effects of proposed legislation--H.R. 1833--on the pay of officers at the U.S. Customs Service. The proposal would amend the 1911 Act governing Customs officers' overtime and premium pay, and it would more closely align Customs differential pay with that of other federal agencies. Should the provision be enacted, Customs officers would be limited to the amount and times for which they would be eligible for night differential pay. In addition, another section of the proposed law would remove premium pay from the calculation of the $30,000 fiscal year overtime and premium pay cap that Customs officers may not exceed. GAO's analysis of Customs data showed that had the provisions of H.R. 1833 been in effect during fiscal year 1999, many officers would have experienced significant pay decreases. Managers and supervisors asked to analyze the proposal had mixed reviews, but those not in favor of the proposal were concerned that less eligibility for night differential pay would lead to low morale and staffing problems."

Energetic Particle Effects Can Explain the Low Frequency of Alfvin Modes in the DIII-D Tokamak
During beam injection in the DIII-D tokamak, modes with lower frequencies than expected for toroidicity-induced Alfvin eigenmodes (TAE) are often observed. We present the analysis of one of these ''beta-induced Alfvin eigenmodes'' (BAE) with a high-n stability code HINST that includes the effect of the energetic ions on the mode frequency. It shows that the ''BAE'' could be the theoretically predicted resonant-TAE (RTAE), which is also called an energetic-particle mode (EPM).

Fish and Wildlife Service: Challenges to Managing the Carlsbad, California, Field Office's Endangered Species Workload
A letter report issued by the General Accounting Office with an abstract that begins "The Fish and Wildlife Service's (FWS) Carlesbad office is developing a computerized project-tracking system for its consultation and habitat conservation planning (HCP) projects. This system, if properly implemented, should improve the office's record keeping and its ability to track the status of projects and help determine why they are in that status. The new system could also improve project management by allowing office managers to determine how long an applicant has been involved in the consultation or HCP process and whether the recommended time frames for completing consultations and the targeted frames for processing HCPs have been exceeded. The Carlsbad office will still have difficulty completing its consultations and HCP projects within recommended or targeted time frames if it is unable to address its staffing problems. An inability to hire new staff and retain existing, experienced staff has made it difficult for the Carlsbad office to meet the demands of its workload. Because the Carlsbad office does not maintain its project files in accordance with federal internal control standards and FWS' guidelines, there has often been confusion between the office and its customers on what was …

Food Safety: Federal Oversight of Seafood Does Not Sufficiently Protect Consumers
A letter report issued by the General Accounting Office with an abstract that begins "Since the Food and Drug Administration (FDA) issued the Hazard Analysis and Critical Control Point system (HACCP) regulations for seafood, the food industry has made some progress in ensuring the safety of seafood. However, several important weaknesses compromise the overall effectiveness of the federal seafood safety system. If left uncorrected, they will continue to undermine the goal of HACCP systems--that is, controlling hazards in the production process before the product reaches the market. More importantly, U.S. consumers may remain at risk of contracting foodborne illness from contaminated domestic and imported seafood products."

Hazardous Waste Code Determination for First/Second-Stage Sludge Waste Stream (IDCs 001, 002, 800)
This document, Hazardous Waste Code Determination for the First/Second-Stage Sludge Waste Stream, summarizes the efforts performed at the Idaho National Engineering and Environmental Laboratory (INEEL) to make a hazardous waste code determination on Item Description Codes (IDCs) 001, 002, and 800 drums. This characterization effort included a thorough review of acceptable knowledge (AK), physical characterization, waste form sampling, chemical analyses, and headspace gas data. This effort included an assessment of pre-Waste Analysis Plan (WAP) solidified sampling and analysis data (referred to as preliminary data). Seventy-five First/Second-Stage Sludge Drums, provided in Table 1-1, have been subjected to core sampling and analysis using the requirements defined in the Quality Assurance Program Plan (QAPP). Based on WAP defined statistical reduction, of preliminary data, a sample size of five was calculated. That is, five additional drums should be core sampled and analyzed. A total of seven drums were sampled, analyzed, and validated in compliance with the WAP criteria. The pre-WAP data (taken under the QAPP) correlated very well with the WAP compliant drum data. As a result, no additional sampling is required. Based upon the information summarized in this document, an accurate hazardous waste determination has been made for the First/Second-Stage Sludge Waste Stream.

In-Situ Electrolyte Replenishment for Long Fuel Cell Life. Phase II Final Report
The carbonate fuel cell has many advantages over conventional methods of producing electricity. It converts hydrocarbon fuels directly into electricity with a high efficiency (>70% in a co-generation plant configuration) and consequently releases less carbon dioxide greenhouse gases (>30% less compared to a combined cycle gas turbine plant). Its adaptability to meet the customers' specific power requirements is ideally suited for distributed power generation. The advantages of distributed power generation include site flexibility, fuel source flexibility, less capital investment risk and elimination of transmission and distribution investments. The fuel cell becomes economically competitive if its life exceeds 40,000h. The current predicted lifetime of the central cells of a stack is 44,000h, based on electrolyte inventory considerations. Methods of extending fuel cell life even further are being sought to enhance its commercial competitiveness.

Information Security: Weak Controls Place DC Highway Trust Fund and Other Data at Risk
A letter report issued by the General Accounting Office with an abstract that begins "GAO reviewed information system general controls over the financial systems that process and account for the financial activities of the District of Columbia's Highway Trust Fund. GAO identified serious computer security weaknesses that place District information at risk of deliberate or inadvertent misuse. These general control problems affected the District's ability to (1) prevent or detect unauthorized changes to sensitive data and (2) control electronic and physical access to confidential information. The District's lack of a comprehensive computer management program was the primary reason for its information system control problems."
