Culture change and lessons learned from ten years in the VA centers of excellence in primary care education

BackgroundTeam-based care is critical to achieving health care value while maximizing patient outcomes. Few descriptions exist of graduate-level team training interventions and practice models. Experience from the multisite, decade-long Veterans Affairs (VA) Centers of Excellence in Primary Care Education provides lessons for developing internal medicine training experiences in interprofessional clinical learning environments.MethodsA review of multisite demonstration project transforming traditional silo-model training to interprofessional team-based primary care. Using iterative quality improvement approaches, sites evaluated curricula with learner, faculty and staff feedback. Learner- and patient-level outcomes and organizational culture change were examined using mixed methods, within and across sites. Participants included more than 1600 internal medicine, nurse practitioner, nursing, pharmacy, psychology, social work and physical therapy trainees. This took place in seven academic university-affiliated VA primary care clinics with patient centered medical home designResultsEach site developed innovative design and curricula using common competencies of shared decision making, sustained relationships, performance improvement and interprofessional collaboration. Educational strategies included integrated didactics, workplace collaboration and reflection. Sites shared implementation best practices and outcomes. Cross-site evaluations of the impacts of these educational strategies indicated improvements in trainee clinical knowledge, team-based approaches to care and interest in primary care careers. Improved patient outcomes were seen in the quality of chronic disease management, reduction in polypharmacy, and reduced emergency department and hospitalizations. Evaluations of the culture of training environments demonstrated incorporation and persistence of interprofessional learning and collaboration.ConclusionsAligning education and practice goals with cross-site collaboration created a robust interprofessional learning environment. Improved trainee/staff satisfaction and better patient care metrics supports use of this model to transform ambulatory care training.Trial registrationThis evaluation was categorized as an operation improvement activity by the Office of Academic Affairs based on Veterans Health Administration Handbook 1058.05, in which information generated is used for business operations and quality improvement (Title 38 Code of Federal Regulations Part 16 (38 CFR 16.102(l)). The overall project was subject to administrative oversight rather Human Subjects Institutional Review Board, as such informed consent was waived as part of the project implementation and evaluation.

Framework for Integrating the Reliability of the Inspection Technique into Risk-Based Inspection Practice

In compliance with recent (2022) federal legislation found in the Code of Federal Regulations Part 650 Subpart C, risk-based inspection (RBI) practices for determining inspection intervals for highway bridges are now permitted. The RBI approach allows for a systematic assessment of risk and prioritizes inspection resources where they are most needed. However, to ensure an optimal level of safety and serviceability, it is necessary to utilize reliable inspection techniques in conjunction with an appropriate inspection interval, as emphasized by National Cooperative Highway Research Program (NCHRP) Report 782. Utilizing ineffective inspection techniques may lead to uncertainty about the element’s condition and thus increase the risk associated with the component. Therefore, this paper proposes a framework that integrates a new factor, called the inspection effectiveness factor (IEF), into the RBI process to rationally estimate the inspection interval considering the reliability of the inspection technique. The inspection interval in the proposed approach is determined based on the damage mode, associated likelihood, consequences, and effectiveness of the inspection technique, offering a rational approach for decision-makers in estimating the inspection interval of bridges and identifying appropriate inspection techniques for different defects. The effectiveness of the proposed method is validated through experts’ judgment. In addition, the proposed approach is demonstrated through a case study utilizing historical inspection reports.

Applying UAS Technologies at Night during a Wildlife Hazard Assessment

Airports operating under the Code of Federal Regulations Part 139 should conduct a wildlife hazard assessment (WHA) when some wildlife-strike events have occurred at or near the airport. The WHA must be conducted by a Qualified Airport Wildlife Biologist (QAWB). The required elements in a WHA include the identification of the wildlife species observed and their numbers and the location of features on and near the airport that could attract wildlife. The collection of data pertaining to mammal populations during a WHA is generally time-consuming, labor-intensive, and costly. Protocols to collect this data include trapping and marking animals and systematic surveys using a spotlight and/or night vision equipment. The purpose of this study was to investigate how UAS technologies could be effectively applied to streamline the QAWB efforts during a WHA at night. Researchers, including students, used a DJI Mavic 2 Enterprise Dual with visual and thermal cameras and a spotlight, as well as a Matrice 210 with a Zenmuse XT2 thermal camera to collect data. Data were collected in a farmland area located two nautical miles south of Daytona Beach International Airport. We applied multiple strategies to mitigate the risks associated with drone operations in an airport environment. The safe application of UAS to streamline the WHA process is anticipated to provide several benefits to the airport operator, including task completion in reduced time, enhanced level of accuracy during the data collection process, reduced risks for the QAWB, and cost efficiencies. Most importantly, researchers expect to develop benchmark safety protocols that can facilitate the effective integration of UAS into the airport environment.

Sleep quality and stress: An investigation of collegiate aviation pilots

Objective: To investigate collegiate aviation pilots’ quality of sleep and psychological distress levels. Participants: Collegiate aviation pilots from a Code of Federal Regulations Part 141 four-year degree-awarding university in central Florida (N = 192). Method: The Pittsburgh Sleepiness Quality Index and the Kessler Psychological Distress Scale were utilized to assess the participants’ subjective quality sleep and psychological distress levels, respectively. A Spearman’s rank-order correlation was run to assess the relationship between quality sleep and distress levels in collegiate aviation student pilots. Results: The prevalence of poor sleep quality among the collegiate aviation pilots was 69%. Mild or severe psychological distress was experienced by 32% (n = 61) of the pilots. There was a strong, positive association between quality sleep and psychological distress (rs (192) = .716, p < .05). Conclusion: Results suggested collegiate aviation programs should promote explicit strategies for students to improve their sleep habits and well-being.

Perspectives on fatigue in short-haul flight operations from US pilots: A focus group study

There are few studies investigating the impact of fatigue in short-haul flight operations conducted under United States (US) 14 Code of Federal Regulations Part 117 flight and duty limitations and rest requirements. In order to understand the fatigue factors unique to short-haul operations, we conducted a series of focus groups across four major commercial passenger airlines in the US. Ninety short-haul pilots were recruited through emails distributed by airline safety teams and labor representatives. Fourteen focus groups were conducted via an online conferencing platform in which participants were asked to identify short-haul schedules and operations that they felt: a) elevated fatigue, b) were not fatiguing, and c) were important to study. Data were collected anonymously and coded using conventional qualitative content analysis, with axial coding and summative analysis used to identify main themes and over-arching categories. The six fatigue factor categories identified were: circadian disruption, high workload, inadequate rest opportunity, schedule changes, regulation implementation and policy issues, and long sits. It appears that additional mitigation strategies may be needed to manage fatigue in short-haul operations beyond the current regulations. Future field studies of short-haul operations in the US should investigate the prevalence and impact of these factors.

Modification in Applying Appendix D of 40 CFR Part 61 to Heated Solid Radionuclide Materials With High Melting and Boiling Points.

Appendix D of Title 40 Part 61 of the US Code of Federal Regulations (CFR) provides a procedure that US Department of Energy (US DOE) facility owners and operators can use to estimate radionuclide emissions to the atmosphere for dose calculations instead of measuring emissions for minor sources under the 40 CFR Part 61, Subpart H, National Emission Standards for Emissions of Radionuclides Other Than Radon From Department of Energy Facilities, regulation. The procedure assumes that any radioactive material heated above 100 °C is completely vaporized and emitted to the atmosphere. In 1991, the US DOE Oak Ridge Reservation (ORR) requested approval to use different release fractions (RFs) for uranium because of its high melting and boiling points. In response to the request, the US Environmental Protection Agency (US EPA) Region IV approved the use of modified RFs for elemental uranium provided no reaction had taken place to alter its chemical form. In 2015, the ORR requested approval to use different RFs for tungsten, again because of its high melting and boiling points. EPA Region IV approved the use of modified RFs for heated radioactive tungsten metal. In accordance with the two precedents set for heating uranium and radioactive tungsten metals, in 2016, the ORR requested approval to use modified RFs in a similar fashion for other radioactive solid metals and compounds with melting and boiling points above 500 °C that might be heated above 100 °C in future research projects and experiments. EPA Region IV again granted approval to use modified RFs for the list of compounds. This note discusses the proposed modified RFs and their development.

A Study of Publicly Available Resources Addressing Legal Data-Sharing Barriers: Systematic Assessment.

BackgroundUnited States data protection laws vary depending on the data type and its context. Data projects involving social determinants of health often concern different data protection laws, making them difficult to navigate.ObjectiveWe systematically aggregated and assessed useful online resources to help navigate the data-sharing landscape.MethodsWe included publicly available resources that discussed legal data-sharing issues with some health relevance and published between 2010 and 2019. We conducted an iterative search with a common string pattern using a general-purpose search engine that targeted 24 different sectors identified by Data Across Sectors for Health. We scored each online resource for its depth of legal and data-sharing discussions and value for addressing legal barriers.ResultsOut of 3710 total search hits, 2721 unique URLs were reviewed for scope, 322 received full-text review, and 154 were selected for final coding. Legal agreements, consent, and agency guidance were the most widely covered legal topics, with HIPAA (The Health Insurance Portability and Accountability Act), Family Educational Rights and Privacy Act (FERPA), Title 42 of the Code of Federal Regulations Part 2 being the top 3 federal laws discussed. Clinical health care was the most prominent sector with a mention in 73 resources.ConclusionsThis is the first systematic study of publicly available resources on legal data-sharing issues. We found existing gaps where resources covering certain laws or applications may be needed. The volume of resources we found is an indicator that real and perceived legal issues are a substantial barrier to efforts in leveraging data from different sectors to promote health.

Design of a Wing Structure for a Single Turboprop Normal Category Aircraft

This paper presents the wing design and structural analysis of a single turboprop aircraft with a maximum take-off weight of 2,200 lbs. The aircraft’s wing structure is a conventional mid-wing configuration of a twisting trapezoidal planform with an aspect ratio of 0.6. The analysis involved determining the loads acting on the wing structure. That is, the aircraft’s flight envelope and the wing’s critical loading condition are according to Title 14 Code of Federal Regulations Part 23 (14 CFR Part 23). The wing CAD model, composed of the aircraft wing components of the spar, ribs, and skins, including its layout, was developed and analyzed based on available 7075T6 Aluminum sheets using the SolidWorks software. The results for the wing’s critical loading condition showed that the wing tip displacement was less than 5% of the half-wingspan with a margin of safety of 0.5 and a mass of 117.97 lbs which was less than the expected mass of 132 lbs.

The Clean Water Act and biosolids: A 45‐year chronological review of biosolids land application research in Colorado

The 1972 U.S. Clean Water Act set forth the generation of biosolids. In Colorado, biosolids land application research began in 1976 and continues today. Pastureland research suggested that sewage effluent could effectively be land applied to benefit aboveground plant growth and to polish water prior to reaching receiving waters. Forest wildfire-affected ecosystems can also benefit from biosolids applications; application rates of up to 80 Mg ha-1 can lead to greater plant establishment, soil microbial activity, and nutrient turnover and reduced nutrient and heavy metal concentrations in runoff below livestock and USEPA drinking water standards. Long-term (24-yr) observations in oil shale-mined lands showed that biosolids (up to 224 Mg ha-1 ) can have a positive effect on microbial-mediated nutrient cycling and, in turn, on aboveground plant community structure. Biosolids applications of up to 40 Mg ha-1 in high-elevation shrubland ecosystems, dominated by Mo-containing shale deposits, can aid in reducing imbalances between Mo and Cu in soils and plants; excessive plant Mo, when consumed by ruminants, can lead to molybdenosis. Biosolids and lime applications (both at 224 Mg ha-1 ) have been shown to improve long-term reclamation success on acid-generating, heavy metal-containing fluvial mine tailings. Thirty years of grazing land research, focused on soil and aboveground plant benefits, illustrate that soil health and plant productivity can be improved to the greatest extent at biosolids application rates close to 10 Mg ha-1 . Finally, 40 yr of dryland agroecosystem research (a) have helped identify biosolids N fertilizer equivalency (∼8kg N Mg-1 ) and thus dryland winter wheat application rates (e.g., 4.5-6.7 dry Mg ha-1 ); (b) have identified first-year mineralization rates of 25-32%; (c) dispute the "time bomb" theory by showing that plant metal uptake follows an exponential rise to a maximum; (d) showcase economic return to producers via increased wheat grain protein content; (e) suggest that biosolids-borne proteins and their degradation products are labile C and N sources; (f) have led to long-term tracking of micronutrients and heavy metals in soils and revealed that plants-soil concentrations will not lead to groundwater degradation and that plants are safe for human consumption; and (g) have shown that biosolids provide Zn, helping to overcome soil deficiencies and enhancing Zn biofortification in wheat grain. This latter point is important because ∼2 billion people globally suffer from Zn deficiencies. Forty-five years of research in Colorado have proven that biosolids can enhance environmental quality, improve soil health, and produce healthy food products.

Recommendations to Inform Substance Use Disorder Data Sharing Research: Scoping Review and Thematic Analysis.

Title 42 Code of Federal Regulations Part 2 (42 CFR Part 2 or Part 2) was enacted in 1975 to protect patients receiving treatment for substance use disorders. A scoping review on Part 2 characterized published work. Seven databases were searched. Studies were categorized based on date of publication, primary objectives, methods, and findings. A thematic analysis was conducted using article titles and abstracts. Of the 36 studies identified, the majority (78%) were opinions or legal reviews, (22%) employed quantitative and/or qualitative methods to study the impact of Part 2, and over half (58%) were published in the past 5 years. Only 8% of studies reported stakeholder involvement in Part 2 studies and no study included patients or patient advocates. No study discussed the efforts to align Part 2 with Health Insurance Portability and Accountability Act or provided evidence of the benefit of this alignment. Three main themes emerged from the review: care delivery (46.6%), law and ethics (27.6%), and technology (25.9%). There were no studies focusing on stigma and its effect on substance use treatment and Part 2. Despite the significance of Part 2, the literature is sparse. It is time to initiate a new era of scholarly research that focuses on the impact of statutes and policies that govern substance use disorder data sharing. Specifically, we recommend research on Part 2 and Health Insurance Portability and Accountability Act alignment, the effects of Part 2 on patients, as well as providers and other stakeholder perceptions on the regulation.

The LORIS MyeliNeuroGene rare disease database for natural history studies and clinical trial readiness

BackgroundRare diseases are estimated to affect 150–350 million people worldwide. With advances in next generation sequencing, the number of known disease-causing genes has increased significantly, opening the door for therapy development. Rare disease research has therefore pivoted from gene discovery to the exploration of potential therapies. With impending clinical trials on the horizon, researchers are in urgent need of natural history studies to help them identify surrogate markers, validate outcome measures, define historical control patients, and design therapeutic trials.ResultsWe customized a browser-accessible multi-modal (e.g. genetics, imaging, behavioral, patient-determined outcomes) database to increase cohort sizes, identify surrogate markers, and foster international collaborations. Ninety data entry forms were developed including family, perinatal, developmental history, clinical examinations, diagnostic investigations, neurological evaluations (i.e. spasticity, dystonia, ataxia, etc.), disability measures, parental stress, and quality of life. A customizable clinical letter generator was created to assist in continuity of patient care.ConclusionsSmall cohorts and underpowered studies are a major challenge for rare disease research. This online, rare disease database will be accessible from all over the world, making it easier to share and disseminate data. We have outlined the methodology to become Title 21 Code of Federal Regulations Part 11 Compliant, which is a requirement to use electronic records as historical controls in clinical trials in the United States. Food and Drug Administration compliant databases will be life-changing for patients and families when historical control data is used for emerging clinical trials. Future work will leverage these tools to delineate the natural history of several rare diseases and we are confident that this database will be used on a larger scale to improve care for patients affected with rare diseases.

Brominated flame retardants (BFRs) in contaminated food contact articles: identification using DART-HRMS and GC-MS

ABSTRACT Any food contact material (FCM) must be approved by the US FDA as being compliant with Title 21 of the Code of Federal regulations Parts 170–199, and/or obtain a non-objection letter through the Food Contact Notification Process, before being placed into the United States market. In the past years, several scientific articles identified FCM or more specifically, food contact articles (FCAs), which were contaminated with brominated flame retardants (BFRs) in the European Union. Prior research has suggested the source of BFR contamination was likely poorly recycled plastics containing waste electrical and electronic equipment (WEEE). We conducted a retail survey to evaluate the presence of BFR-contaminated reusable FCA in the US market. Using a Direct Analysis in Real Time ionisation High-Resolution Mass Spectrometry (DART-HRMS) screening technique and extraction gas chromatography-mass spectrometry (GC-MS) confirmation we were able to identify BFRs present in retail FCAs. Among non-targeted retail samples, 4 of 49 reusable FCAs contained 1–4 BFRs each. The identified BFRs, found in greatest estimated concentrations, were 2,4,6-tribromophenol (TBP), 3,3ʹ,5,5ʹ-tetrabromobisphenol A (TBBPA), hexabromocyclododecane (HBCD), decabromodiphenylethane (DBDPE) and decabromodiphenylether (BDE-209). A second targeted FCA sampling (n = 28) confirmed these BFRs persisted in similar articles. Combined sample sets (n = 77) estimated DART false-positive/negative incidences of 5% & 4%, respectively, for BFR screening of FCAs. Because the presence of BFRs in some contaminated FCAs has been demonstrated and since these compounds are possible migrants into food, further studies are warranted. In order to estimate the potential exposure of the identified BFRs and conduct corresponding risk assessments, the next and logical step will be to study the mass transfer of BFRs from the contaminated FCM into food simulants and food.

21 Code of Federal Regulations Part 11-Compliant Digital Signature Solution for Cancer Clinical Trials: A Single-Institution Feasibility Study.

Inefficiencies in the clinical trial infrastructure result in protracted trial completion timelines, physician-investigator turnover, and a shrinking skilled labor force and present obstacles to research participation. Taken together, these barriers hinder scientific progress. Technological solutions to improve clinical trial efficiency have emerged, yet adoption remains slow because of concerns with cost, regulatory compliance, and implementation. A prospective pilot study that compared regulatory-compliant digital and traditional wet ink paper signatures was conducted over a 6.5-month period in a hospital-based health system. Staff time and effort, error rate, costs, and time to completion were measured. Wilcoxon rank sum tests were used to compare staff time and time to completion. A value analysis was conducted. A survey was administered to measure user satisfaction. There where 96 participants (47 digital, 49 paper), 132 studies included (31 digital, 101 paper), and 265 documents processed (156 digital, 109 paper). A moderate reduction in staff time required to prepare documents for signature was observed (P < .0001). Error rates were reported in 5.1% of digital and 2.8% of paper documents, but this difference was not significant. Discrepancies requiring revisions included incomplete mandatory fields, inaccurate information submitted, and technical issues. A value analysis demonstrated a 19% labor savings with the use of digital signatures. Survey response rate was 57.4% (n = 27). Most participants (85.2%) preferred digital signatures. The time to complete documents was faster with digital signatures compared with paper (P = .0241). The use of digital signatures resulted in a decrease in document completion time and regulatory burden as represented by staff hours. Additional cost and time savings and information liquidity could be realized by integrating digital signatures and electronic document management systems.

Development of a risk indicator score card for a large, flight training department

The purpose of the research was to create and validate a single, quantitative indicator of flight risk for a Title 14 of the Code of Federal Regulations (CFR) Part 141 flight training department to increase the accuracy of the Risk Management and Safety Assurance components of the department’s Safety Management System (SMS). The researchers created and validated, via expert elicitation, a non-statistical model composed of twelve Safety Performance Indicators (SPIs) from both flight and maintenance operations and their relevant formulas. These were based on two years of flight-performance data from a 14 CFR Part 141 flight training department in the Southeast United States. Once the SPIs had been quantified, standardized, and assigned a weighted value, they were used to create a Risk Indicator Score Card capable of portraying the risk associated with flight operations; maintenance operations; and overall, combined operations on a monthly basis.

A Good Practice-Compliant Clinical Trial Imaging Management System for Multicenter Clinical Trials: Development and Validation Study.

BackgroundWith the rapid increase in utilization of imaging endpoints in multicenter clinical trials, the amount of data and workflow complexity have also increased. A Clinical Trial Imaging Management System (CTIMS) is required to comprehensively support imaging processes in clinical trials. The US Food and Drug Administration (FDA) issued a guidance protocol in 2018 for appropriate use of medical imaging in accordance with many regulations including the Good Clinical Practice (GCP) guidelines. Existing research on CTIMS, however, has mainly focused on functions and structures of systems rather than regulation and compliance.ObjectiveWe aimed to develop a comprehensive CTIMS to meet the current regulatory guidelines and various required functions. We also aimed to perform computerized system validation focusing on the regulatory compliance of our CTIMS.MethodsKey regulatory requirements of CTIMS were extracted thorough review of many related regulations and guidelines including International Conference on Harmonization-GCP E6, FDA 21 Code of Federal Regulations parts 11 and 820, Good Automated Manufacturing Practice, and Clinical Data Interchange Standards Consortium. The system architecture was designed in accordance with these regulations by a multidisciplinary team including radiologists, engineers, clinical trial specialists, and regulatory medicine professionals. Computerized system validation of the developed CTIMS was performed internally and externally.ResultsOur CTIMS (AiCRO) was developed based on a two-layer design composed of the server system and the client system, which is efficient at meeting the regulatory and functional requirements. The server system manages system security, data archive, backup, and audit trail. The client system provides various functions including deidentification, image transfer, image viewer, image quality control, and electronic record. Computerized system validation was performed internally using a V-model and externally by a global quality assurance company to demonstrate that AiCRO meets all regulatory and functional requirements.ConclusionsWe developed a Good Practice–compliant CTIMS—AiCRO system—to manage large amounts of image data and complexity of imaging management processes in clinical trials. Our CTIMS adopts and adheres to all regulatory and functional requirements and has been thoroughly validated.

Intensive Archaeological Survey of the Proposed SAWS NWC Bulverde/1604 Sewer Extension Project, San Antonio, Bexar County, Texas

On behalf of Oden Hughes, Pape-Dawson conducted an intensive archaeological survey of the proposed NWC Bulverde/1604 Sewer Extension Project in San Antonio, Bexar County, Texas. The project proposed to begin on the southwest side of Classen Road approximately 0.2 kilometers (km) (0.13 mile [mi]) east of its northern intersection with Bulverde Road. The proposed line would parallel Elm Waterhole Creek to the west and south approximately 0.8 km (0.5 mi). At this point, the line would cross Autry Pond Road in a southwestern direction eventually paralleling Bulverde Road to the intersection of Redland Road for a total length of approximately 0.4 km (0.25 mi). This project would entail the installation of 1.2 km (0.75 mi) of new sewer line within a 5-meter (m) (16-foot [ft])-wide permanent easement and an adjacent 8-m (25-ft)-wide temporary easement along whichever side was available. The Area of Potential Effects (APE) for the proposed project was defined as a 30 m (100 ft) buffer centered on the proposed SAWS centerline totaling 3.7 hectares (ha) (9.18 acres). The depth of vertical impacts was not yet been determined, but utility installations typically require 1.8 to 2.4 m (6 to 8 ft). Notably, the sewer alignment was changed after completion of this archaeological survey and installation will no longer take place in this APE. The survey for the new alignment was completed under Texas Antiquities Permit #8870. Although Oden Hughes would construct the new sewer line, San Antonio Water Systems (SAWS) would be the grantee of the easement after construction. For this reason, compliance with the Antiquities Code of Texas (ACT) was required. In addition, this project would require a Nationwide Permit from the U.S. Army Corps of Engineers (USACE). Thus, compliance with Section 106 of the National Historic Preservation Act (NHPA) (Title 36 Code of Federal Regulations Part 800.4 [36 CFR 800.4]) was required. In addition, the project was located within the San Antonio city limits, which necessitated compliance with the Historic Preservation and Urban Design Section of the City of San Antonio (COSA) Unified Development Code (UDC). Pape-Dawson conducted the intensive archaeological survey on September 20, 2017. The entirety of the APE was subject to visual inspection supplemented by judgmentally placed shovel tests in order to evaluate the potential for buried cultural resources. This work was conducted under Antiquities Permit No. 8161 with Virginia Moore, M.A.G. serving as Principal Investigator. A total of 16 shovel tests was excavated within the APE, all of which were negative for archaeological material. During this survey, one previously recorded site (41BX1786) was revisited within the limits of the APE. However, no cultural deposits associated with the site were encountered. Given the absence of artifacts observed during the current survey, Pape-Dawson recommends that 41BX1786 is ineligible within ROW for State Antiquities Landmark (SAL) and National Register of Historic Places (NRHP) designation. No archaeological resources were located or recorded during this survey. As no properties were identified that meet the criteria for listing in the National Register of Historic Places (NRHP) according to 36 CFR 60.4, or for designation as a State Antiquities Landmark (SAL) according to 13 Texas Administrative Code 26.12 (13 TAC 26.12), Pape-Dawson recommends that no further archaeological work is necessary for the proposed undertaking as presently designed. However, if undiscovered cultural material is encountered iii during construction, it is recommended that all work in the vicinity should cease and the THC and COSA archaeologists be contacted to ensure compliance with the NHPA, ACT, and UDC. No artifacts were collected, but all project records and photographs will be curated at the Center for Archaeological Research (CAR) at the University of Texas at San Antonio.

Evaluation of Partial Flow Dilution Systems for Very Low PM Mass Measurements

Particulate matter (PM) mass measurement methodologies were improved considerably with the application of Title 40 Code of Federal Regulations Part 1065 for the 2007 standards for heavy-duty engines that emphasized PM. However, there is still a need to improve the understanding of and the confidence in mass measurements for light-duty vehicles, which are now being subjected to more stringent PM standards. The purpose of this study is to evaluate commercially available partial flow dilutors (PFDs), with a particular focus on their equivalency with the standard constant volume sampler (CVS) tunnel method and the ability to provide reproducible measurements at low PM emission levels. For the main PFD comparison, simultaneous testing was conducted with the three PFDs, over federal test procedure (FTP) and US06 tests. The results of the calibrations and proportionality tests all showed good performance for the PFDs. The exhaust flow meters (EFMs) for the PFDs showed measurements within 2% or less of a calibration source. The PFDs also showed good level proportionality and can easily meet the CFR 1066 requirements for light-duty vehicles and 1065 requirements for all tests performed. Larger differences were seen for the main comparisons between the CVS and the different PFDs during the FTP testing, with the relative difference of PM emissions between the PFDs and the CVS varying from − 16.5 to − 0.6%, with an average pooled difference of − 8.5%. These FTP differences only represented 0.00 to 0.11 mg/mile on an absolute basis, however, and could be attributed to difficulties making and weighing filter mass measurements at such low levels. For the US06 cycle, the differences between the PFDs and the CVS were not statistically significant and ranged from − 6.7 to − 0.7% and up to 0.07 mg/mile.

Measurement of automobile N2O from bag and continuous stream by quantum cascade laser spectroscopy

N2O emission from automobile has been regulated by the United States Environment Protection Agency due to its higher global warming potential compared to CO2. Responding to this, an instrument for fast sensing of ultra-low concentration of N2O from automobile has become an urgent need. In this study, an instrument based on the quantum cascade laser spectroscopy has been developed and applied for certification testing of ultra-low N2O in automobile exhaust. The pulsed quantum cascade laser can emit coherent lights in the mid-infrared region where N2O shows strong absorption and better control of wavelength. Therefore, a very low detection limit can be achieved and interference of co-existing gases can be avoided using a super fine resolution of the mid-infrared spectrum. The US Code of Federal Regulations Parts 1065/1066 allows measuring N2O from sample storage bags, from a continuous dilute stream or a raw exhaust stream. Typically, batch (bag) sampling has better accuracy and repeatability, but continuous sampling is more efficient in terms of test cell running time and provides test-mode emissions. In this study, the quantum cascade laser analyzer has been applied to investigate correlations between bag sampling and continuous dilute exhaust sampling using a fleet of vehicles with a wide range of N2O emission levels all meeting United States Environment Protection Agency emission standards. Very good correlation between these two sampling methods was observed for the majority of tests conducted and in best case the difference was less than ±1%. The direct injection gasoline vehicle emits higher N2O than conventional port injection gasoline vehicles. The quantum cascade laser analyzer has been successfully applied for United States Environment Protection Agency N2O certification test.

Hand Held Technology; Its Place In a Environmental Compliance Monitoring System

This abstract will examine the elements of a field deployable inspection application designed to support the U S Environmental Protection Agency's (USEPA) field mission assignment, through the use of hand held technology. The system is designed to mimic a typical inspection through the use of software applications that replicate hard copy inspection forms. The primary elements of the program are in support of the Spill Prevention Control and Countermeasures (SPCC) regulations codified in Title 40 Code of Federal Regulations Part 112. These regulations govern prevention related activities, Facility Response Plans (FRPs) reviews and Government Initiated Unannounced Exercises (GIUEs). Accordingly, digital inspection/evaluation forms were created utilizing File Maker Pro development software. The forms have been deployed on Apple's IPAD tablets which allow for the integration of locational attributes of Google maps and the tablet's built in digital camera. A typical inspection will consist of an Administrative Form, Notice of Inspection (NOI), SPCC Inspection checklist, FRP Review checklist, FRP Field checklist, FRP Approval Letters and when applicable a GIUE evaluation forms. These files combine to form a complete inspection folder where it is either closed out as compliant or submitted to enforcement for further deliberation. A typical inspection begins with general inspection data being entered into the Administrative Form. Data entered here auto populates each corresponding inspection form. As an added enhancement, each inspection form can be pre- populated with consistently recorded values. This is generally the case when conducting multiple inspection where the company remains the same and/or the consultant has prepared plans in a uniform/standardized manner. Consequently, both latitudinal/longitudinal attributes are automatically embedded within the application along with photographic data. Upon completion of the inspection, the data is then synchronized with a GoZync Application with File Maker Pro server via WIFI or cellular connection. After file completion and administrative review, the report can be emailed to the recipient in a PDF format. To date, field trials have been completed on a local level with the expectation that Branch wide deployment will commence in late FY 16. The Agency recently made a nationwide buy of Apple tablets for On Scene Coordinators (OSCs) as well as inspection personnel within the response program. This helped pave the way for new application development and bringing to fruition the Agency's desired mission to perform its duties in a digital environment.
