NOTICE OF INTENT TO ISSUE A CLEAN AIR ACT 

TITLE V FEDERAL OPERATING PERMIT

The Region 9 office of the United States Environmental Protection Agency (EPA) requests 

public comment on a draft Operating Permit for the Tri-Cities Landfill, a closed, municipal solid 

waste treatment and disposal facility located in Scottsdale, Arizona on the reservation of the Salt 

River Pima-Maricopa Indian Community.

This source is required to obtain a Clean Air Act Title V Operating Permit in accordance with 40 

CFR Part 71. The permit contains all the Clean Air Act requirements that apply to the source and 

requires that the source conduct monitoring sufficient to enable US EPA and the public to 

determine whether the source is complying with the applicable air quality requirements. This 

proceeding is subject to the administrative requirements of 40 CFR 71.11.

A copy of the draft permit prepared by US EPA, the statement of basis for the draft permit, the 

application, and all supporting materials submitted by the source are available for review by the 

public at the following locations:

1) At the offices of the Salt River Pima-Maricopa Indian Community, 13602 Beeline 

Highway, Scottsdale, Arizona 85256

2) By contacting the permit writer, Eugene Chen, at (415) 947-4304 or 

chen.eugene@epa.gov, or by writing to:

Eugene Chen (AIR-3)

U.S. EPA, Region 9

75 Hawthorne Street

San Francisco, CA 94105

3) At the US EPA Region 9 office (address above), Monday through Friday, from 9:00 

A.M. until 4:00 P.M., excluding federal holidays

4) Online at the US EPA Region 9 website at: http://www.epa.gov/region9/air/permit/r9-

permits-issued.html#pubcomment

5) Online at www.regulations.gov under Docket ID No. EPA-R09-OAR-2013-0612

Pursuant to 40 CFR 71.11(f), EPA shall hold a Public Hearing if the Regional Administrator 

finds, on the basis of requests, a significant amount of public interest in a draft permit. Requests 

for a Public Hearing must contain the reasons for requesting a hearing. If a Public Hearing is 

granted, a public notice stating the date, time and place of the hearing will be made at least 30 

days prior to the hearing and the comment period will be extended through the hearing date.

A legal ad to be published in the Arizona Republic on August 20, 2013 will announce EPA’s 

proposal to issue the renewed Title V permit. All comments upon or objections to the draft 

permit and requests for a Public Hearing must be sent or delivered to Eugene Chen at the address 

shown above by September 19, 2013. An extension of the 30-day comment period may be 
granted if the request for an extension adequately explains why more time is required to prepare 

comments. All comments received prior to the end of the public comment period and all 

comments made during a public hearing will be considered in arriving at a final decision on the 

permit. The final permit is a public record that can be obtained upon request. A statement of 

reasons for changes made to the draft permit and responses to comments received will be sent to 

all persons who commented on the draft permit.

If you believe any condition of the draft permit is inappropriate or that our initial decision to deny an 

application, terminate a permit, or prepare a draft permit is inappropriate, you must raise all 

reasonably ascertainable issues and submit all reasonably ascertainable arguments supporting your 

position by the end of the comment period.

If you would like to be added to the mailing list for updates on a particular facility or for updates on 

EPA’s Title V Operating Permit program, please contact EPA at the address listed above. Please 

bring the foregoing notice to the attention of all persons who you know would be interested in this 

matter.
