Attribution of Haze Report Status
Fire Emissions Joint Forum Meeting

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.

Colorado Attribution of Haze Project
Rocky Mountain National Park Individual Class I Area Report Attribution of Haze Project
Rocky Mountain National Park is located abreast the Continental Divide in north central Colorado. Terrain is mountainous and varied, with elevations ranging from near 2,500 m (8,000 ft) at valley bottoms to a high of 4,347 m (14,259 ft) at Long's Peak. Due to its location on the Divide, the western slope is directly impacted by prevailing westerly winds and receives more precipitation than the eastern slope which is in the rain shadow of the Rockies. The town of Estes Park averages 13.1 inches of precipitation; the town of Grand Lake 19.95 inches per year. The National Park includes the headwaters of the westward flowing Colorado River and eastward flowing Cache la Poudre and Thompson Rivers. An IMPROVE monitoring site, ROMO1, is just east of the Park boundary, at an elevation near 2,750 m (9,020 ft).
