Re: Technical Addendum for the Request for

Redesignation and Maintenance Plan for

Fine Particle Attainment in the

Southwestern Indiana Nonattainment Area

The Indiana Department ofEnvironmental Management (IDEM) has prepared this technical

addendum to the Request for Redesignation and Maintenance Plan for Fine Particle Attainment in the

Southwestern Indiana Nonattainrnent Area (Redesignation Request and Maintenance Plan) to

incorporate 2008 quality assured ambient air quality monitoring data for fine particles. The final

Request for Redesignation and Maintenance Plan was submitted to U.S. EPA on April 3, 2008.

The table and charts listed below show the updated quality assured ambient air quality

monitoring data for fine particles through 2008. A map ofthe Southwestern Indiana Fine Particle

Nonattainment Area is also included for reference.

Quality assured ambient air quality monitoring data for fine particles for the years 2004 through

2008 (three consecutive design value periods) demonstrate that the Southwestern Indiana Area has

attained the annual NAAQS for fine particles and is eligible for redesignation. The 2006-2008

monitoring data for the Southwest Indiana Area is complete (Le. no missing data.) United States

Environmental Protection Agency and Lake Michigan Air Directors Consortium modeling for future

year design values consistently show that existing and future improvements in air quality in the region

due to declining emissions resulting from permanent and enforceable control measures will ensure

continued compliance (maintenance) with the standard. FurthelIDore, because this area is subject to

significant transport ofpollutants, significant regional nitrogen oxides (NOx) and sulfur dioxide (S02)

reductions will ensure continued compliance (maintenance) with the standard with an increasing

margin ofsafety. Therefore, the Southwestern Indiana Area is eligible for its air quality status to be

classified consistent with other counties in the nation that measure air quality that meets the annual

NAAQS for fine particles.

IDEM believes that this technical addendum in conjunction with the previously submitted

Redesignation Request and Maintenance Plan satisfies Indiana's obligation under Section 172(c) ofthe

Clean Air Act to demonstrate how the area attained, and will continue to attain, the NAAQS for fine

particles by the attainment date.

Therefore, IDEM requests that U.S. EPA proceed with final review and approval ofthe

Redesignation and Maintenance Plan for Fine Particle Attainment in the Southwestern Indiana

Nonattainment Area. If you have any questions or need additional information, please contact Mr.

Scott Deloney, Chief, Air Programs Branch, at (317) 233-5694 or sdeloney@idem.IN.gov, or Ms.

Christine Pedersen, Chief, Air Planning Section, at (317) 233-5684 or cpederse@idem.IN.gov.
