Re: State Implementation Plan Rule Revisions' 

Dear Ms. Miller: 

Enclosed for your review and approval are an original and four copies of revisions to the 

Department of Environmental Quality's (DEQ) Rules for the Control of Air Pollution in Idaho, 


IDAPA 58.01.01. DEQ is seeking Environmental Protection Agency (EPA) approval of the 


following revisions as an update to the contents of the Idaho State Implementation Plan (SIP), 

40 CFR, Part 52, Subpart N: 

IDAPA Docket 58-0101-0601 - Regional Haze 

IDAPA Docket 58-0101-0602 - Annual Incorporation by Reference (2006) 

IDAPA Docket 58-0101-0603 - Prohibition Against Construction of EGUs as defined in 40 CFR 

60.24 

These revisions to the state rules were promulgated pursuant to the Environmental Protection 

and Health Act, Idaho Code, Sections 39-101 through 39-130. Review and approval by a DEQ 

Deputy Attorney General was obtained at appropriate times throughout the rulemaking process. 

Rule adoption was made in accordance with the requirements of the federal Clean Air Act and 

applicable federal regulations. None of the revisions included in this submittal reflect a reduction 

in emission limits. 

As a follow-up to previous submittals, DEQ forwarded the following rule changes to EPA on May 

22, 2003, April 2, 2004, July 13, 2005 and May 5, 2006 for inclusion in the Idaho SIP. We 

understand these documents will be reviewed by your staff in the future. We mention these 

dockets here only for purposes of ensuring previous submittals do not slip from the SIP priority 

I~t . 

Docket 58-0101-0102 - Soil Vapor Extraction 


Docket 58-0101-0103 - (a) Hospital/Medical/Infectious Waste Incinerators, and
