### Dear Mr. Palmer: Enclosed for your considerationis the final revision to Kentucky's State Implementation Plan: Kentucky's Attainment Demonstration for areas not meeting the annual PM2.5 Standard. These areas include: the Kentucky counties of Jefferson and Bullitt that are part ofthe Louisville, KY-IN PM2.5Nonattainment Area, the Kentucky counties of Boone, Campbell, and Kenton that are part of the Cincinnati-Middletown, OH-KY-IN PM2.5Nonattainment Area, and the Kentucky counties of Boyd and a portion of Lawrence, that are part of the Huntington-Ashland WV-KYOH PM2.5Nonattainment Area. The attainment demonstration, based on modeling performed by the Visibility Improvement State and Tribal Association of the Southeast and the Association of Southeastern Integrated Planning (VISTASIASIP) provides documentation that each area will attain the annual PM2,5 standard by April 5, 2010. Ohio, Indiana, and West Virginia are making separate attainment demonstrations for their respective portions of the metropolitan areas and have submitted those demonstrations to U.S. EPA, Regions 5 and 3. The Ohio and Indiana demonstrations, which also document attainment for the entire nonattainment area, are based on modeling performedby LADCO (Lake Michigan Air Directors Consortium).
A public hearing to receive commentson this revision was held on July 31,2008, at 1:30 p.m. EDT at the offices of the Kentucky Division for Air Quality in Frankfort, Kentucky. A copyofthe public hearing notice and the statementofconsiderationis included in this submittal.

### RE: Clarification regarding theDecember 3,2008 Attainment Demonstration for areas not meeting the 1997annual PM2 5NAAQS Dear Mr. Schutt: This letter is to clarify the mobile source insignificant finding for the HuntingtonAshland WV-KY-OH area that was included in the PM2.5 attainment demonstration that the Kentucky Division for Air Quality (division) submitted to U.S. EPA on December 3, 2008. The demonstration compared the mobile emissions (Section 8.0) for the nonattainment portion of Lawrence County, to the point, area, and nonroad sectors of the entire county (Section 3.5). Based on guidance from Region 4, the division has revised the emissions from all sectors to reflect the Kentucky portion ofthe nonattainment area and provided a summary of the percentage of mobile emissions in Table 1. The differences are miniscule due to the large contribution of emissionsfrom the Big Sandy power plant. Table 1

The division has attached updated Tables 8.2-3 to 8.2-5 to provide a detail of the emissions inventory for the nonattainment portion of Lawrence County. Columns have been added to the tables to indicate the emissions of the nonattainment area for point, area, and nonroad sectors and then a revised emissions total has been added to the end of the table. The point sector emissions for the nonattainment area were determined by removing those facilities that are located outside the nonattainment area. The area and nonroad emissions of the nonattainment were updated based on a population apportionment. The population ofthe census tract is 1,050 and the population of the entire county is 15,569. Therefore, the census tract of the nonattainment area is 

### 7% of the population of the county, and the area and nonroad emissions in the nonattainment area were reduce to 7.0% of the entire county emissions. As stated earlier, the differences in emissions are inconsequential, and continue to support a finding of insignificance for mobile emissions budgets. If you have any questions or comments concerning this matter, please contact Andrea Smith with the Division for Air Quality at (502) 564-3999.
