Approval and Promulgation of Implementation Plans and Operating Permits Program; State of Iowa

EPA is approving a State Implementation Plan (SIP) revision submitted by the state of Iowa for the purpose of clarifying that only untreated wood, seeds, pellets and other vegetative matter may be burned in fuel burning equipment and residential heating units; to remove a reference to a boiler that was removed at a power and water facility, and to clarify the language with regard to continuous emissions monitoring. One administrative correction to the operating permit program is also included in this revision. Approval of these revisions will ensure consistency between the state and Federally- approved rules, and ensure Federal enforceability of the state's revised air program rules.
