EPA is approving a request from Ohio to amend its State Implementation Plan (SIP) emission statement reporting regulation. The request to revise Ohio's SIP was submitted by the Division of Air Pollution Control on May 1, 2006, and supplemented on May 22, 2007. Ohio held a public hearing on these revisions on September 8, 2005. The SIP revision concurrently rescinds and revises portions of Ohio Administrative Code Chapter 3745-24 to be consistent with the Clean Air Act (CAA) emission statement program reporting requirements for stationary sources. The revision makes the rule more general to apply to all counties designated nonattainment for ozone, and not to a specific list of counties. The rationale for approval and other information are provided in this rulemaking action.
