Logansport exceeded its allowable visible emission limit for opacity at its coal-fired boilers, Units #5 and #6. While performing an inspection at the facility from June 30 to July 1, 2008, EPA personnel conducted visible emission readings in accordance with 40 C.F.R. Part 60, Appendix A, Method 9. On July 1, 2008, visible emission readings exceeded the forty percent (40%) opacity limit at Units #5 and #6. The alleged violations were cited in a Notice of Violation and Finding of Violation (NOV/FOV) issued to Logansport on September 19, 2008. EPA alleged that Logansport was in violation of the forty percent (40%) opacity standard, found in 326 IAC 5-1-2(1)(A) of the Indiana State Implementation Plan (SIP) and incorporated into LogansportÂs Title V operating permit.
To resolve the alleged violation, Logansport will obtain and burn low-sulfur coal with a contract specification between eight-tenths percent (0.80%) and one and five-tenths percent (1.50%) sulfur. The facility will submit monthly composite coal analysis reports to EPA. Logansport will submit a permit modification request to the Indiana Department of Environmental Management in which they will commit to burning a low-sulfur coal. Logansport will perform stack testing at Units #5 and #6. Additionally, the facility will commit to spending $400,000 on environmental mitigation projects.
