The Louisville-Southern Indiana Ohio River Bridges (LSIORB) Project is located within the U.S. Environmental Protection Agency's designated Louisville, KY-IN region PM2.5 non-attainment area. As such, the project is required to meet Transportation Conformity Rule requirements found in 40 CFR Part 93. The Transportation Conformity Rule requires a hotspot analysis as part of the project-level conformity in PM2.5 non-attainment areas for certain projects. The January 8, 2007 document titled "Final PM2.5 Project-Level Conformity Analysis for the Ohio River Bridges Project in Louisville, Kentucky" addresses the new project-level transportation conformity requirements for the LSIORB project. This report was made available to the public for review and comment for a period of 15 days, between November 21, 2006 and December 6, 2006. On January 4, 2007, the Federal Highway Administration made an air quality particulate matter (PM2.5) conformity determination that the LSIORB project met the requirements of 40 CFR 93.
The PM2.5 project-level analysis conducted for the LSIORB project found that by meeting the requirements of 40 CFR Part 93, that the project will not:
- cause or contribute to any new violation of the PM2.5 standard;
- increase the frequency or severity of any existing violation of the PM2.5 standard; or
- delay timely attainment of the PM2.5 standard.
