### Based on its EPA-approved 

### Part 70 Operating Permi t Program, 

### the Tri 

### e meets 

### the eligibi lity criteria for up -front delegation of authorit y to implement and enforce AA section 111 and 112 standards. Notwithstanding that EPA's final approval ofthe Tribe ' s Pan 70 Ope, ting Pennit Program alone sa tisfies the criteria for up-front approval, enclosed in further su ort of the Tribe's applicati on 

### for authorizat ion to implement and 

### enforce Section 11 1 an 112 standards is a 

### copy of the Southern Ute Indian Tribe/State of 

### Colorado Environmental Co mission's 

### Reservation Air Code
. The Reservation Air Code includes the specific implementa ion and enforcement procedures required by CAA Section Ill( c)', as well as the complianc procedures required by CAA Section 112(1 ) (5). The Tribe · s legal authority to implement and enforce CAA programs o the Southern Ute Indian Reservation has not changed since submittal ofthe Tribe's application or approval of its Part 70 Operating Permit Program. A ddi tionally, the Tribe anticipates that im lementation and enforcement ofthe Section 111 and 112 standards will be carried out c ncurrently with the 

### adm inistration of its Part 70 

### program, using the same resources to imp**~mcnt** 

### and enforce a rule or program 

### will not vary tor this and subsequent approval applications Therefore, the Tribe understands there is no need to resubmit this information 

### .tor subseque t adoption of

### future sec tion 11 I or section l 12 rules, emission standards, and other requireJ ents 

### by the Environmental Commission. Ifchanges occur regarding the adequacy f the Tribe ·s legal author ity**~nd** resources to implement and enforce section Ill or sectio 112 standards, the Tribe 

### will modify its applications to retlcct 

### these changes. The Tribe commits to recommendjng to the Environmental Commissi 1 the adoption of section 11 I and section 112 s tandards int.o the Reservation Air Code unchang through incorpo r ation 

### by reference. The Tribe requests automatic delegation of section 1 11 d 1 12 standards upon adoption into the 

### Resc:rvation Air Code. Once the 

### Environmental Co mission incorporates the specific standards 

### by reference, 

### it is our understanding 

### that the Tribe v. 

### i1l become theimplementing and enforcing authority for those standards. If lhe F.nvir
. omental Commission changes a rule. emission standard, or other requirement 

### in 

### any way, ev n substituting "director" for ''administratur" , then the! Tribe understands that formal evaluation d delegation must occur. Based on the intonnation included in this program authorization requ · t. the Tribe requests that EPA Region 8 delegate authority to the Tribe to implement and enfore CAA section Ill (c) and 112(1) standards for both part 70 and non-part 70 sources. If you have any qucsnons regarding thls matter. please feel free contac Ms. Brenda Jarrell, the Tribe's Air Quality Program Manager, at 970.563.4705. ext. 2246.
