**SUPPLEMENTARY INFORMATION:**
In the September 9, 2016 (81 FR 62387), *Federal Register* direct final action approving revisions to part 52, chapter 22 of Iowa's SIP, EPA inadvertently omitted a minor administrative phrase from rules 567-22.4, 567-22.5, and 567.22.10. This technical part 52 revision to 567-22.5 is also being applied to Iowa's 112(l) plan.
This technical revision is also making corrections to the Region 7 Technical Support Document (TSD) that supports the September 9, 2016 (81 FR 62387), direct final action. EPA inadvertently omitted minor administrative phrases and a reference from chapter 22 rule 567-22.103. Two revisions to chapter 22 rule 567-22.105(2) are required for clarification. Please see the revised TSD included in the docket.
Finally, we are revising the incorrect state effective dates codified on page 62398 of the September 9, 2016 (81 FR 62387), *Federal Register* for parts 52 and 70. The correct state effective date is December 16, 2015.
Additional information for this technical amendment can be found in the revised Technical Support Document located in this docket.
