ENVIRONMENTAL PROTECTION AGENCY

[FRL-9774-5]


Notice of Issuance of Prevention of Significant Deterioration 
Modification and Part 71 Operating Permit Renewal to NRG Backup 
Generation Services

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: This notice announces that on November 26, 2012, EPA issued a 
Modification to a Prevention of Significant Deterioration (PSD) permit 
to NRG Backup Generation Services. NRG Backup Generation Services owns 
and operates four diesel-fired generators for Treasure Island Resort 
and Casino on land held in trust for the Prairie Island Indian 
Community in Red Wing, Minnesota. The modified PSD permit changes the 
required interval of nitrogen oxide performance testing for the four 
engines from every three years to every five years. In a separate 
action on November 26, 2012, EPA issued a title V permit to operate 
renewal to NRG Backup Generation Services pursuant to title V of the 
Clean Air Act. This permit authorizes NRG Backup Generation Services to 
operate the four diesel-fired generators for peak load management and 
backup power at the casino.

DATES: During the public comment period, which ended on October 19, 
2012, EPA received a comment on the modified draft PSD permit and draft 
title V permit. Therefore, in accordance with 40 CFR 124.15(b) and 
71.11(i)(2), both permits became effective on December 26, 2012.

ADDRESSES: The final signed permits are available for public inspection 
online at http://yosemite.epa.gov/r5/r5ard.nsf/Tribal+Permits!OpenView, 
or during normal business hours at the following address: U.S.

SUPPLEMENTARY INFORMATION: This section provides supplemental 
information by answering the following questions:

A. What is the background information?
B. What is the purpose of this notice?

A. What is the background information?

    NRG Backup Generation Services, formerly Energy Alternatives, Inc., 
owns and operates four diesel-fired generators for Treasure Island 
Resort and Casino in Red Wing, Minnesota. All four generators are 
located on land held in trust for the Prairie Island Indian Community. 
The generators are used for peak load management and backup power at 
the casino.
    On August 14, 2007, Energy Alternatives, Inc. submitted to EPA an 
application to change the nitrogen oxide performance testing interval 
from every three years to every five years. EPA approved this change 
based on previous performance testing results.
    In October 2008, Energy Alternatives, Inc. submitted an application 
to renew its title V permit.
    EPA first made available for public comment a draft Federal title V 
permit during a public comment period that ended on May 10, 2010. On 
May 10, 2010, EPA received a comment from Energy Alternatives, Inc. 
explaining that the requested change to the nitrogen oxide performance 
testing interval was not included in the title V permit. Since the 
testing interval was established in a PSD permit and since title V 
permits cannot change PSD requirements, a modification to the PSD 
permit was required.
    On September 19, 2012, EPA made available for public comment a 
draft Federal PSD permit modification, Permit No. PSD-PI-2704900084-
2012-02, which included the nitrogen oxide testing interval requested 
by Energy Alternatives. On the same day, EPA made available for public 
comment a draft Federal title V permit to operate, Permit No. V-PI-
2704900084-2012-10. This title V permit incorporated all applicable air 
quality requirements for the four diesel-fired, emergency and peak load 
sharing generators Energy Alternatives owned and operated at Treasure 
Island Resort and Casino, including the monitoring necessary to ensure 
compliance with the requirements of the permit. In accordance with the 
requirements of 40 CFR 124.10(b)(1) and 71.11(d), EPA provided the 
public with 30 days to comment on both draft permits.
    During the public comment period, EPA received one comment from NRG 
Backup Generation Services notifying EPA that ownership of the four 
diesel-fired engines changed from Energy Alternatives, Inc. to NRG 
Backup Generation Services. EPA finalized both permits and provided 
copies to the applicant pursuant to 40 CFR 124.15(b) and 71.11(i).
    EPA is not aware of any outstanding enforcement actions against NRG 
Backup Generation Services and believes the issuance of these permits 
is non-controversial.

B. What is the purpose of this notice?

    EPA is notifying the public of the issuance of the PSD permit 
modification and title V operating permit to NRG Backup Generation 
Services on November 26, 2012. Since EPA received a comment on the 
draft PSD permit modification and the draft title V permit, both 
permits became effective on December 26, 2012, pursuant to 40 CFR 
124.15(b) and 71.11(i)(2).

    Authority: 42 U.S.C. 7401 et seq.

    Dated: January 17, 2013.
