Additionally, the amended rules as published in the 567 Chapters 20, 22, 23, 25, 31, and 33 of 

the Iowa Administrative Code, are available on the Iowa Legislature's website at 

https://www.legis.iowa.gov/law/administrativeRules/agencies. (Scroll down to Environmental 

Protection Commission (567), click on Chapters, scroll down to the chapter of interest, and select 

either the PDF or RTF options.) 

The Department requests that EPA revise Iowa's SIP to incorporate the amendment specified in 

Items 1-11,22, and 23 of the enclosed Adopted and Filed rulemaking. Items 12-17 and 21 are 

specifically excluded from this request. 

The Department also requests that EPA update the "Delegation of Authority for New Source 

Performance Standards and National Emission Standards for Hazardous Air Pollutants by the 

U.S. Environmental Protection Agency, Region VII to the State ofiowa under §111 and §112 of 

the Clean Air Act." to incorporate Items 18, 19, and 20 of the enclosed Adopted & Filed 

rulemaking. The amendments rescind Iowa's adoption by reference of these specific§ 111 and 

§ 112 standards because Iowa has no facilities affected by these standards and likely will not have 

affected facilities in the future.
