Description
The Environmental Protection Agency (EPA) is taking final action to approve revisions to the Iowa State Implementation Plan (SIP) and the Operating Permit Program to incorporate recent changes to the Iowa Administrative Code (IAC). The revisions include removal of the Voluntary Operating Permit (VOP) Program language, removal of the Emission Reduction Program language, implementation 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. The EPA is also finalizing corrections to the erroneous incorporation of several rules into the Iowa SIP pursuant to the Clean Air Act (CAA). These revisions do not decrease the stringency of the SIP or adversely affect air quality. The final approval aligns with CAA requirements.
