Technical Status Report May 5, 2006 (Updates & changes to sections of this report from earlier status reports are noted in bold italics.) Contact: Tom Moore, Technical Coordinator (970.491.8837) or mooret@cira.colostate.edu Background The purpose of this ongoing series of status reports is to periodically describe what and when technical work products from WRAP Forums and Workgroups or other sources will be available for use in the regional haze planning process through 2006 and into early 2007. Progress on regional haze planning and technical work to date indicates that some WRAP technical activities to support the 2007 plan development process will need to continue into the first half of 2007, and that technical support will need to continue after mid-2007. Those activities through mid-2007 are reflected in updates to Sections A and B of this document. As planned, a major milestone encompassing regional technical work will be the delivery of the complete picture of that work in October 2006. Descriptions of the individual projects are in the WRAP workplan, and methods and details about the data (how and why the work was done) are also available from contractor reports or websites, or from the Technical Coordinator. This update is specific to work accomplished through April 2006, and describes plans to date for future technical analyses. The status report is organized as follows: Section A - Access and content of existing data nodes; Section B - Progress updates for key existing and planned work product deliverables from Forums and Workgroups, summarized from the project descriptions in the current WRAP Workplan Update for 2005-07 http://wrapair.org/WRAP/documents/05-07Workplan_final.pdf (a workplan update for 2006-07 is in preparation); Section C - The Regional Modeling Center 2006 schedule and workplan; and Section D - Highlights and brief descriptions of selected specific analyses and projects related to regional haze planning accomplished in the past few months. A) Existing Data Nodes Visibility Information Exchange Web System (VIEWS) - http://vista.cira.colostate.edu/views/ – this system provides ongoing access to IMPROVE and other visibility monitoring data, research results, and special studies related to the Regional Haze Rule. Downloads of the IMPROVE data, custom displays of spatial, chemical, and temporal patterns, as well as information about applying monitoring data for regional haze planning are available. This information will be used in the Phase II Attribution of Haze (AoH) project during 2005-06. This system was originally sponsored by the Ambient Monitoring & Reporting Forum, and currently has national coverage through sponsorship by all 5 RPOs through September 2006. The complete preliminary dataset from Regional Haze Rule Baseline Period (2000-04) as measured by the IMPROVE monitoring network has been posted, and Class I area-specific data are available for review, including 5-year averages of the Best and Worst 20% visibility days and glide paths from baseline period averages to EPA default natural conditions. The IMPROVE Steering Committee has approved a revised light extinction equation, and VIEWS staff are working to implement that option for calculating deciviews and other haze metrics using either the old/existing equation (circa 1988) or the revised (circa December 2005) light extinction equation. Both of those options should be available in April 2006. In addition, there is an analysis project underway to assess and possibly improve the default EPA natural conditions estimates, incorporating the revised IMPROVE light extinction equation and improved statistical analyses, to cover the greater number of IMPROVE monitoring sites and the associated increase in the available data. Discussions on this analysis project and the consequences of the results will be hosted by the Attribution of Haze Workgroup and the Technical Oversight Committee during the next few months. Causes of Haze Assessment project (CoHA) - http://coha.dri.edu/index.html - this ongoing project of the Ambient Monitoring & Reporting Forum project is completing detailed analyses of IMPROVE and meteorological monitoring data in the WRAP region. Work to date includes multi-year back trajectory wind plots for each monitored Class I area, trajectory regression analyses’ results used in the Phase I AoH project, and extensive descriptive information about the monitoring data and each Class I area. Planned work for 2005-06 will be used include trend analyses and receptor modeling using the Positive Matrix Factorization (PMF) technique to relate source types and regions to the 2000-04 baseline period monitoring data, also to be used in AoH Phase II. Analyses of the long-term trends in the IMPROVE visibility data for monitoring sites with 8 to 16 years of record are available at: http://coha.dri.edu/. The CoHA project team is completing the 5-year (2000-04) back trajectory analyses for each IMPROVE site for various air quality conditions (worst/best visibility days, worst sulfate days, et cetera), expanding the 3-year trajectories already complete at: http://coha.dri.edu/web/general/trajgallery/trajmapgallery.html. CoHA is also completing an analysis of “was 2002 a typical/representative meteorological year”; that analysis and the 5-year trajectories will be used in the AoH Phase II project. Also, the CoHA team is actively working on applying the PMF receptor modeling technique to 2000-04 IMPROVE data in the WRAP region, with the goal of identifying source types at the Class I areas, and specifically separating and determining the amount of smoke from fire emissions versus urban carbon emission. The PMF analyses support the May 23-24 Smoke/Carbon/Dust Workshop and AoH Phase II. Emissions Data Management System (EDMS) - http://wrapedms.org/default_login.asp - this ongoing project of the Emissions Forum is an emission inventory data warehouse and web-based GIS application that provides a consistent, complete, and regional approach to emissions data tracking to meet the requirements for SIP and TIP development, periodic progress reviews, and data updates. The EDMS serves as a central regional emissions inventory database for all types of emissions, and uses associated software to facilitate the data collection efforts for regional modeling, emissions tracking and associated data analyses. Baseline and future years’ emissions data will be stored and accessed here, with the displays and regional summaries to be used in AoH Phase II. Use of the EDMS is based on user registration and periodic listserv updates, requires a password for ad-hoc data queries, but is open to all interested users. The EDMS has been updated with 2002 point, area, mobile, and fire emissions, and EDMS will continue to have additional inventory data added over the next several months. Testing of the EDMS for functionality and operational performance was completed by the end of 2005. The EDMS is being revised by the contractor to address concerns and problems found in the testing. The 2018 emissions inventories are being loaded into EDMS. The Emissions Forum is developing and implementing a plan to operate the EDMS in a cost-efficient and effective fashion. Regional Modeling Center (RMC) - http://pah.cert.ucr.edu/aqm/308/ - the objective of this ongoing project of the Air Quality Modeling Forum is to provide the necessary technical and policy tools needed by states and tribes for the Regional Haze Rule. The substantial effort by the RMC is intended to support State and Tribal agencies in conducting regional haze analyses in the western United States. This analysis is being performed by operating regional scale, three-dimensional regulatory air quality models that simulate the emissions, chemical transformations, and transport of criteria pollutants and fine PM and consequent effects on visibility in Class I areas in the WRAP region and across North America. Responsibilities of the RMC include: 1) Emissions processing and modeling; 2) Air quality and visibility modeling simulations; 3) Analysis, display, and reporting of modeling results, and 4) Storage/quality assurance of the modeling input and output files. The RMC offers periodic listserv updates, provides data and technology transfer support, and uses monthly conference calls to 2 review work products. Results from the RMC work will be used extensively in the AoH Phase II project. A complete status report on RMC activities for the March 2004 through February 2005 period was completed in August, and a report on 2002 base year “model performance evaluation” simulation work performed by the RMC during 2005 is also complete, see: http://pah.cert.ucr.edu/aqm/308/reports/final/2002_MPE_report_main_body_FINAL.pdf. The RMC has developed a detailed workplan outline and budget for 2006 to largely complete regional modeling work as well as supporting the BART modeling needs of the states, see additional information in Section C, below. The RMC completed 3 regional modeling runs in late 2005, 1) base02a – modeling actual 2002 emissions data as of August 2005; 2) plan02a – modeling typical emission for the 2000-04 time period, that included 2002 updated final actual emissions as of November 2005 for most source categories, but used 2000-04 fire emissions estimates and average operation factors for power plants; and 3) base18a – modeling 2018 base case emissions projections (rules/permits on the books as of 12/04) for anthropogenic sources, with fire and other “quasi-natural” sources held constant. These modeling results were presented at the January 10-11 WRAP workshop in Tucson – see: http://wrapair.org/forums/ioc/meetings/060110m/index.html. The “b” versions of each of those simulations are planned for March-May 2006. In addition, the RMC website at: http://pah.cert.ucr.edu/aqm/308/index.shtml has been reorganized for easier use. The regional visibility modeling results are available under the “Visibility Modeling” tab, addressing CMAQ and CAMx results from various modeling scenarios, source apportionment analyses, and sensitivity studies. The table at the top of this page under this tab allows the user access to a specifications sheet for each modeling run, the emissions associated with that run, and the analysis and findings. The RMC has added a “BART CalPuff Modeling” tab at: http://pah.cert.ucr.edu/aqm/308/bart.shtml. The RMC is supporting and tracking technology transfer of data and modeling tools through the “Data Transfer” tab at: http://pah.cert.ucr.edu/aqm/308/data_transfer.shtml. Technical Support System (TSS) - http://vista.cira.colostate.edu/wraptss/ - the TSS is being developed as a project of the Attribution of Haze Workgroup (http://wrapair.org/forums/aoh/TSS/index.html) to provide a single portal to support regional haze planning using the regional technical data, analytical results, and tools prepared by the WRAP’s Forums and Workgroups. The key data and summary results displayed on the TSS are intended to support the air quality planning needs of western state and tribes, and will be maintained and updated to support both the implementation of regional haze plans and other Western air quality analysis and management needs. The primary initial and ongoing purpose of the TSS is to be the one-stop shop for access, visualization, analysis, and retrieval of the technical data and regional analytical results prepared by WRAP Forums and Workgroups in support of regional haze planning in the West. The TSS specifically summarizes results and consolidates information about air quality monitoring, meteorological and receptor modeling data analyses, emissions inventories and models, and gridded air quality/visibility regional modeling simulations. These copious and diverse data are integrated for application to air quality planning purposes by prioritizing and refining key information and results into explanatory tools. Finally, a major goal of the TSS is to make the standard and user-specified maps, charts, tables, and graphs easily available for export, while maintaining the original source data available for verification and subsequent analysis through the TSS. There is active collaboration with the Implementation Workgroup and all the WRAP Forums and Workgroups as to the content, format, and level of information detail on the TSS. The first TSS Training/Orientation session was held on April 27th. The TSS is built upon the foundation and uses tools and techniques developed for the VIEWS system described above; the WRAP plans to fund the TSS on an ongoing basis and maintain support of VIEWS functions through the TSS. 3 B) Overview of WRAP 2005-07 Key Technical Deliverables (May 2006 update, gray cells complete) Time Frame Responsible Group/Subject Emissions Forum Fire Forum (Phase 2 EI project) Deliverable (completion target month) Operational version of Emissions Data Management System (EDMS) with actual 2002 EI for WRAP region.

See: http://www.wrapair.org/forums/dejf/documents/defdust/Saguaro_West_Case_Study_ReportDRAFT_mar06-.pdf. Please provide comments to Lee Alter. The Fire Emissions Joint Forum has recently completed review of results for several projects: Small Fire Sensitivity Modeling, see: http://pah.cert.ucr.edu/aqm/308/results_Base02a12k_vs_Base02a12kfire/RMC_small_fire_sensitivity_final.p pt The FEJF is considering the next steps in applying these results to the tracking of fire emissions for regional haze plans. Evaluation of Fire Tracking Systems, see: http://www.wrapair.org/forums/fejf/meetings/060307m/FTS_Eval_1030a.ppt. The FEJF is developing a white paper to guide the implementation of a WRAP FTS. Guidance for Regional Coordination of Smoke Management Programs, see: http://www.wrapair.org/forums/fejf/meetings/060307m/RCG-Version7Redlined-MtgDraft.pdf The Stationary Sources Joint Forum is forming workgroups to refine the initial oil and gas emissions inventories and coordinate BART engineering analyses. The Ambient Monitoring & Reporting Forum’s Causes of Haze Assessment project is developing a method and preparing results for receptor modeling analyses using a technique called Positive Matrix Factorization, see: http://www.coha.dri.edu/web/general/tools_PMFModeling.html for more information. These monitoring data-based source apportionment results will be used in the AoH Phase II project, and are a complement to the source apportionment analyses conducted by the Regional Modeling Center using a regional gridded dispersion model. 16
