Dear Dr. Lakin:

During the summer of 2008, an unusually intens ive outbreak of lightning strikes from a

series of dry thunderstorms ignited an unprecedented summer fire season. Extensive

impacts occurred across Northern and Central California

, with smoke and haze lingering

over the region for much of the summer. Num erous monitoring sites, comprising both

Federal Reference Method and Federal Equivalent Method monitors, recorded elevated

particulate matter (PM) concentration levels, with many days above the National

Ambient Air Quality Standards for both PM2.5 and PM10

. The California Air Resources

Board is requesting exclusion of data from 33 monitoring sites in 15 Air Districts where

smoke caused levels to exceed those historically seen during the summer particulate

season. Documentation on these wildfire smoke even ts and their impact on air quality

are enclosed.

On March 22, 2007, t he United States Environmental Protection Agency (U.S. EPA)

adopted the Treatment of Data I nfluenced by Exceptional Events rule that allows data to

be flagged and thus excluded from cons ideration by U.S. EPA when making decisions

related to the attainment status of an area. This rule, which became effective on May

22, 2007, requires that States submit documentation to support flagging to the

appropriate U.S. EPA Regional Office.Mr. Matthew Lakin, Ph.D.

We are therefore formally requesting you concur that these exceedances are PM 2.5

and PM 10 natural events and send us confirmation by letter. If you have any questions

regarding the enclosed documentation please contact Ms. Sylvia Zulawnick, Manager,

Particulat e Matter Analysis Section, at (916) 324
