Attribution of Haze Work Group: Phase I (ARS)

The overall objective of the Attribution of Haze project is to prepare a policy-level report describing the emission source categories and geographic source regions presently contributing to visibility impairment, at each of the over 100 federal and tribal Class I areas in the WRAP region. Air Resource Specialists, Inc. (ARS), was contracted to prepare this report for Phase I of the project, expected to be completed in January 2005. The Phase I report will provide state and tribal air regulators with an initial detailed assessment of the geographic regions and source categories affecting the Class I areas for which they are responsible and will be an integral part of the interactive process the WRAP will pursue toward providing regulators with the information and tools they need to meet the 2007 regional haze plan deadline. For more information regarding the Phase I AoH report, please contact Joe Adlhoch at ARS.
