These revisions include removal of outdated programs such as the Voluntary Operating Permit Program and the Emission Reduction Program, introduction of new and renumbered rules, replacement of duplicative language with references to state statute and federal regulations, updated definitions, consolidation of 14 chapters into 8 chapters, and minor clarifications to language and grammar. Additionally, the EPA proposes to correct erroneous incorporations of several rules into the Iowa SIP pursuant to section 110(k)(6) of the Clean Air Act. The revisions do not decrease the stringency of the SIP or adversely affect air quality and align with Clean Air Act requirements.
