Attribution of Haze Work Group: About

The Technical Analysis Forum was formed in December 2006 by the Technical Oversight Committee; the TAF assumed responsibility for combining the participants and maintaining the activities and ongoing projects of the Ambient Air Monitoring & Reporting Forum, the Air Quality Modeling Forum, and the Attribution of Haze Workgroup. The existing project and report materials from the 2 Forums and the AoH Workgroup will be archived on their existing webpages, and all updates to their projects will be displayed on the TAF pages beginning in January 2007.

WRAP Technical Support System Launched (11/8/06)
The first complete version of the TSS, which supports regional haze planning in the WRAP region, is available for use. The TSS incorporates key data summaries, analysis and exploration tools, and method descriptions. A summary presentation describing the status of TSS pages was reviewed at the November 2-3, 2006 Attribution of Haze Workgroup meeting. This presentation is a helpful guide to using the TSS, and also identifies ongoing activities to support and continue development of the TSS.

As called for in the WRAP Strategic Plan, the Technical Oversight Committee has formed a workgroup to oversee the 2004 Attribution of Haze project. The AoH project will result in a January 2005 report describing the emissions source categories and geographic source regions presently contributing to visibility impairment at each mandatory federal and tribal Class I area in the WRAP region. The AoH workgroup will be integrating analytical results and data from monitoring, emissions, and modeling analyses. The AoH workgroup includes the TOC, as well as representatives from the technical and joint Forums, the IOC, and the state and tribal caucuses. For more information, please contact Tom Moore.

Attribution of Haze Workgroup Releases Final Phase I Report (03/15/05) The AoH Workgroup, with support from Air Resource Specialists, has completed the final Phase I report describing the emissions source categories and geographic source regions presently contributing to visibility impairment at each mandatory federal and tribal Class I area in the WRAP region. The report accomplishes this by integrating results from ambient monitoring, emissions inventory, and air quality modeling analyses. For more information, please contact Tom Moore.
