SUMMARY: The Gila River Indian Community (GRIC) has developed a 

comprehensive Tribal Implementation Plan (TIP) to manage air quality at GRIC. The 

TIP contains numerous ordinances which are designed to limit air pollution from a 

variety of industrial, area and general sources within the Community. The GRIC TIP 

ordinances also establish a permitting program for industries classified as Title V (major) 

and Non-Title V air pollution sources under the federal Clean Air Act. 

The Tribal Implementation Plan (TIP) contains several ordinances including permit 

requirements and fees, administrative appeals procedures, enforcement (civil and 

criminal), non-metallic mineral mining (aggregate mining, asphalt plants and concrete 

plants), secondary aluminum processing operations, solvent metal cleaning, Volatile 

Organic Compound (VOC) usage, storage and handling, aerospace manufacturing and 

rework processes, open burning and visible emissions ordnances. The TIP also adopts 

the November 1,2004 version of the federal New Source Performance Standards (NSPS) 

and National Emission Standards for Hazardous Air Pollutants (NESHAPs). In some 

cases, the Community is adopting standards that are more stringent than the federal 

standards. The GRIC TIP contains a detailed permit program for both Title V sources 

and Non-title V sources and sets the process for making changes at industrial facilities. 

The Community is not proposing to implement the major source New Source Review 
(NSR) nor the major source Prevention of Significant Deterioration (PSD) provisions of 

the CAA. The Environmental Protection Agency (EPA) will continue to implement these 

sections of the CAA at GRIC. The TIP also adopts the National Ambient Air Quality 

Standards (NAAQS) as GRIC Standards. 

PUBLIC HEARING: This notice invites all members of the public to a hearing on the 

proposed GRIC Tribal Implementation Plan for Air Quality Management. As required 

under the Clean Air Act, the Gila River Indian Community is providing an opportunity 

for interested parties to submit comments on the Implementation Plan through a formal 

public hearing or to the GRIC Department of Environmental Quality during the public 

comment period (below). 

PUBLIC COMMENT PERIOD: In addition to the public hearing, the DEQ is 

accepting comments during a public comment period (May 13,2005 thru July 1,2005). 

All written and verbal comments submitted to the DEQ during the public comment 

period will become part of the public record. 

The DEQ will summarize, in writing, all public comments, recommended responses to 

those comments and any changes to the proposed ordinances based on the comments. 

Comments may be submitted at either the public hearing, directly to the DEQ in writing 

or via e-mail at the address below. The DEQ will submit the comments and 

recommended responses to GRIC Committees and Council along with the proposed form 

of ordinances before requesting Council to enact the TIP. 

Once the TIP is enacted by the Community Council, the TIP ordinances, comments and 

responses and support documentation will be submitted to the U.S. Environmental 

Protection Agency (EPA) Region IX for approval. After approval by EPA the GRIC TIP 

will become federally enforceable.
