Subject: Gila River Indian Community's Request for Delegation of New Source 

Performance Standards (NSPS) and National Emission Standards for 

Hazardous Air Pollutants (NESHAPs) 

Dear Ms. Jordan, 

GRlC hereby formally requests delegation to implement and enforce the National 

Emission Standards for Hazardous Air Pollutants (NESHAP) under CAA 5 112 and the 

Standards of Performance for New Stationary Sources (NSPS) under CAA $ 1 1 1. In 

accordance with the November 10,2008 Memorandum of Agreement (MOA), GRlC has 

incorporated by reference the NESHAPs at 40 C.F.R, Parts 61 and 63, and the NSPSs at 

40 C.F.R Part 60, into the GRlC Air Quality Management Program Plan. These 

standards are codified in the GRlC Code at Title 17, Chapter 9, Part II. GRlC commits to 

expeditiously implement and enforce these standards upon EPA approval of this request. 

The GRlC Air Quality Management Plan and referenced NSPS and NESHAP 

requirements have under gone an extensive public outreach process, public notice, and 

public hearing process in accordance with Sections 1 10 and 301(d) of the Clean Air Act. 

In addition, the GRlC Air Quality Management Plan has been ratified into Tribal law by 

the Community Council under resolution (attached). 

GRlC's mechanism for obtaining the regulatory authority necessary to accept delegation 

is through incorporation of the federal rules by reference into the GRlC Tribal Code. The 

following subparts of 40 C.F.R. Parts 61 and 63 (NESHAPs) and 40 C.F.R. Part 60 

(NSPSs), and all accompanying appendices, adopted as of July 1,2006, and no future 

additions or amendments, have been incorporated by reference into the GRlC Code at 

Title 17, Chapter 9, Part II.

The Gila River Indian Community acknowledges that delegation 

constitutes our agreement to follow all applicable provisions of 40 CFR 

Parts 60,6 1, and 63, including the use of U.S. EPA's test methods and 

procedures. In the event that a Gila River Indian Community Air Quality 

Ordinance contains a requirement that is more stringent than a NESHAPS 

or NSPS requirement, the more stringent requirement shall apply. We 

also understand that U.S. EPA retains the exclusive right for authorizing 

approval of equivalent and alternative control technologies and test 

methods. Therefore, we understand that the applicable subsections of the 

requested NSPS and NESHAP may not be delegated. 
The Gila River Indian Community requests that EPA review this 

NESHAP and NSPS delegation submittal as expeditiously as possible. If
