Abstract
EPA is approving requests submitted by the Indiana Department of Environmental Management (IDEM) on December 21, 2005 and June 27, 2006 to revise the Indiana State Implementation Plan (SIP) in two areas: to amend 326 IAC 1-3-4, ambient air quality standards, to provide consistency between State and Federal reference conditions for measurements of particulate matter air quality; and to update the references to the Code of Federal Regulations (CFR) from the 2002 edition to the 2004 edition.
