Regional Technical Operations Work Group

Overview

• Regional analyses in support of planning activities related to emissions and modeling for regional haze, ozone, PM, and other indicators.
• Evaluation of background and regional transport, international transport, sensitivity and other analyses of emissions data focused on the western U.S.
• Perform and leverage modeling, data analysis, and contribution assessment studies.
• Investigation of “background ozone” impacts to western U.S. locations.
• Coordination and collaboration with other WRAP member-sponsored regional air quality modeling groups including IWDW, NW-AIRQUEST, EPA-OAQPS, BAAQMD, and otherstate and local agencies performing regional ozone modeling.
• Provide guidance on more complete and uniform model performance evaluations (MPEs).
• Develop and implement a protocol to use the IWDW-WAQS capabilities as the WRAP Regional Technical Center.
