Abstract
Indiana requested on December 31, 2008, that EPA approve as a revision to its State Implementation Plan (SIP) alternative monitoring requirements for the Indianapolis Power and Light Company (IPL) at its Harding Street Generating Station. The alternative monitoring requirements allow the use of a particulate matter (PM) continuous emissions monitoring system (CEMS) in place of a continuous opacity monitor system (COMS).
