Mr. Alan Merson 

Regional Administrator 

Environmental Protection Agency Region VIII Suite 103 

1860 Lincoln Street 

Denver, CO 80295 

Dear Mr. Merson: 

Enclosed with this letter is the Revised Utah State Implementation 

Plan (SIP). Nine additional copies of the plan and regulations have been 

forwarded to Mr. Marius Gedgaudas of your staff for distribution as . necessary for the EPA review; five technical support documents will be 

forwarded to Mr. Gedgaudas before January 15, 1979. 

It is felt that the revised SIP eliminates the need for the EPA 

regulations promulgated as replacements for portions of the original Utah 

SIP which EPA considered inadequate in attaining the National Ambient Air 

Quality Standards. Consequently, with exception of 40 CFR 52.2345, revocation of 40 CFR Subpart TT is requested. We will prepare another 

revision to the SIP within the next several months to acquire control of 

the prevention of significant deterioration of air quality program and 

will ask for revocation of 40 CFR 52.2345. 

The revised SIP demonstrates attainment of the secondary NAAQS 

throughout the particulate non-attainment area excepting in small areas 

near the Kennecott tailings dump in Salt Lake County and the USS Geneva 

Works in Utah County. As permitted under Section 110, Clean Air Act as 

amended August 1977, Utah requests an eighteen month extension until
