Summary

EPA is proposing to approve revisions to particulate matter (PM) emissions regulations for Indianapolis Power and Light Company (IPL) in Marion County, Indiana, which were submitted by the Indiana Department of Environmental Management (IDEM) on November 22, 1999, as amendments to its State Implementation Plan (SIP). The revisions apply to 3 IPL generating stations located in Indianapolis: Perry K, Perry W (demolished), and E. W. Stout. The revisions include relaxation of some PM limits, tightening of other limits, and the elimination of limits for several boilers which are no longer operating. The revisions also include the combination of annual emissions limits for several boilers, and correction of a typographical error in one limit. This SIP revision results in an overall decrease in allowed PM emissions of 52.54 tons per year. An air quality modeling analysis conducted by the IDEM shows that the maximum daily and annual impacts of this SIP revision are well below established significance levels. Therefore, this SIP revision will not have an adverse effect on PM air quality.

Dates

EPA must receive written comments on this proposed rule by March 24, 2000.
