WestJumpAQMS

The Western Governors’ Association (WGA), on behalf of the Western Regional Air Partnership (WRAP), is coordinating state, local, and federal agency involvement in a large regional 2008 baseline year air quality modeling study called the West-wide Jumpstart Air Quality Modeling Study (WestJumpAQMS). The study is supported by three expert technical contractors to WGA and western public air quality and land management agencies for the study. The WGA prime contractor is ENVIRON International Corporation (ENVIRON), with Alpine Geophysics and the University of North Carolina - Chapel Hill as subcontractors. The objectives of the WestJumpAQMS are as follows:

  • Initiate the next generation of regional technical analysis and support for Ozone and Particulate Matter (PM) transport and attainment demonstrations across the West.
  • Implement the concept developed by New Mexico Environment Department Air Quality Bureau, EPA Region 6, the Bureau of Land Management (BLM) New Mexico state office, British Petroleum (BP), and the Western Regional Air Partnership (WRAP) to begin the next round of base-year regional modeling to support western U.S. air quality planning.
  • Advance the interests and support the technical data needs of the BLM national air program and BLM State Offices’ air quality staff (MT-ND, WY, UT, CO, and NM) for consistent future NEPA air quality analyses.
  • Continue work conducted by WRAP’s Regional Modeling Center (RMC) from 2001-09 to provide regionally complete emissions and air quality modeling across the western U.S.
    • RMC modeling products became the basis for many state air agency and federal land manager air analyses across the West, including numerous NEPA studies, the Denver Ozone study, and the Four Corners Air Quality Task Force (FCAQTF) work, among others. The regional collaboration enabled by the WRAP RMC was effective and efficient for state and regional air quality planning. The WestJumpAQMS will enable the application of WRAP-IPAMS regionally consistent and comprehensive work to compile Oil and Gas VOC and NOx emission inventories.
  • Leverage recent modeling and monitoring analyses suggesting Spring season transport of both natural ozone and international emissions are occurring in elevated rural terrain in the spring and such events approach the level of the Ozone National Ambient Air Quality Standard (NAAQS).
  • Provide a modeling platform that incorporates technical updates and improvements to photochemical grid models, to begin addressing the next generation of air quality issues related to Ozone, PM (PM2.5 and PM10), visibility, and nitrogen deposition.
