WRAP - Regional haze analyses, Web development, and database design
ARS recently supported the Western Regional Air Partnership (WRAP) by working cooperatively with western state air agency representatives to prepare a Regional Haze Rule (RHR) technical support document, which is intended to provide the technical basis for Western States to develop the first of their individual reasonable progress reports. It includes regional, state, and CIA specific summaries that characterize the difference between baseline conditions (2000-2004) and first successive progress period (2005-2009). Background information on progress period support materials, including documentation regarding the 2008 emissions data summarized on the TSS, is also available in this support document.

ARS played a key role in the development of the WRAP Technical Support System (TSS) (http://vista.cira.colostate.edu/tss/), a Web-based portal to technical data and analytical results required to support the air quality planning needs of western states and tribes.

MMS - Gulf of Mexico Air Quality Database
ARS teamed with ICF International to support a Gulf of Mexico data compilation and analysis project for the Minerals Management Service. ARS' contribution is the development of a Gulf of Mexico Air Quality Database and user interface to organize and serve up 15 years' worth of ambient air quality, particulate, meteorological, and emissions data.

VISTAS - Regional haze and PM non-attainment analyses
ARS scientists support VISTAS (the Visibility Improvement State and Tribal Association of the Southeast) with regional haze analyses. ARS finalized a variety of speciated aerosol analyses for Class I areas, meteorological back trajectories, and visual image modeling to understand causes and effects of regional haze, PM2.5 analyses for Environmental Protection Agency non-attainment areas, and supporting methods documentation.

Environment Canada - Lessons learned from the U.S. Regional Haze Rule
On behalf of Environment Canada, ARS conducted a survey of key stakeholders in the U.S. Regional Haze Rule (RHR) process. To ensure a broad representation of the lessons learned, the survey included participants from the EPA, Regional Planning Organization (RPO) leadership, U.S. Federal Land Managers (FLMs), state representatives, a key consultant, and industry stakeholders. Survey questions focused on stakeholders' perceptions of:

  • The usefulness and limitations of monitoring, emissions and modeling methodologies, resulting datasets, and tracking metrics.
  • Policy considerations and agency roles within the RHR process.
  • Expected effectiveness of haze reduction strategies and meeting RHR milestones.
  • Specific lessons British Columbia (and other regions in Canada) can learn from the U.S. experience in developing a visibility program.
