RE: Fine Particulate (PM25) National AmbientAir Quality Standard (NAAQS) Area AttainmentDesignation Recommendations for Counties in the State ofArkansas.

Dear Mr. Curry:

The NAAQS for Particulate Matter (PM) was revised in a final rule dated January 15, 2013, with an effective date ofMarch 18,2013. In this rulemaking, EPA promulgated a revised primary annual NAAQS for PM2

_ 5 of I2.0 11g/m3 averaged over a 3-year period to replace the existing primary annual standard of 15.0 11g/m3 and retained the primary 24-hour PM25 standard at 35 11g/m3• The previous primary standards for PM 10

. as well as the secondary standards for PM25

. also remain unchanged. Section 107(d)(l) of the Federal Clean Air Act requires state governors to recommend attainment status designations within one year ofthe promulgation of any new orrevised NAAQS. This letter provides such recommendations as set forth below.

All monitored counties in Arkansas currently meet the existing primary and secondary PM25 Standards with the exception of Pulaski County, which would exceed the new Primary Standard based on the Design Value for calendar years 2010-20I2. However, based on the data collected to date for 2013, we expect all Arkansas counties to attain the Standards by the time EPA makes final designations in 2014. For this reason, Arkansas is making a preliminary designation recommendation of attainment or unclassifiable for all Arkansas counties. Final designation recommendations will be submitted when the 2013 data is complete and quality assured, based on the 2013 Design Value. The attached table lists all Arkansas counties and their recommended designations. For further information regarding these recommendations, please contact Mike Bates, Chief- Air Division, Arkansas Department of Environmental Quality, at 501-682-0000 orby e-mail at bates@adeq.state.ar.us.
