Download as PDF 68058 Federal Register / Vol. 74, No. 244 / Tuesday, December 22, 2009 / Notices Region 4, at (404) 562–9115 or hofmeister.art@epa.gov. ENVIRONMENTAL PROTECTION AGENCY The CAA affords EPA a 45-day period to review and, as appropriate, the authority to object to operating permits proposed by state permitting authorities under title V of the CAA, 42 U.S.C. 7661–7661f. Section 505(b)(2) of the CAA and 40 CFR 70.8(d) authorize any person to petition the EPA Administrator to object to a title V operating permit within 60 days after the expiration of EPA’s 45day review period if EPA has not objected on its own initiative. Petitions must be based only on objections to the permit that were raised with reasonable specificity during the public comment period provided by the state, unless the petitioner demonstrates that it was impracticable to raise these issues during the comment period or the grounds for the issues arose after this period. Petitioner submitted a petition regarding the EKPC Spurlock Generating Station on April 28, 2008, requesting that EPA object to Revision 2 to the EKPC merged PSD and title V operating permit. Pursuant to a proposed Consent Decree, EPA agreed to address the issue regarding the lack of hazardous air pollutant emission limits under section 112(g) of the CAA in an order that was issued on September 21, 2009. The remaining two issues are addressed in this Order. The issues are: (1) The permit revision proposed by KDAQ fails to include the required heat input limit applicable to Unit 2 and unlawfully attempts to increase that limit without going through PSD (or any other CAA title I) permitting and (2) KDAQ’s review of low-sulfur coal was not adequate. On November 30, 2009, the Administrator issued an Order both granting and denying, in part, the petition with respect to the remaining two issues. The Order explains EPA’s rationale for granting the petition with respect to issue 2 and denying the petition with respect to issue 1.

ACTION: Notice. SUMMARY: This notice announces that, on October 2, 2009, pursuant to Title V of the Clean Air Act, EPA issued a Title V Permit to Operate (Title V permit) to Great Lakes Gas Transmission Limited Partnership (Great Lakes Gas). This permit authorizes Great Lakes Gas to operate two natural gas-fired turbine/ compressors and one natural gas-fired standby electrical generator at Compressor Station #4 (CS#4) near Deer River, Minnesota. CS#4, which is located on privately-owned fee land within the exterior boundaries of the Leech Lake Band of Ojibwe Indian Reservation, adds pressure to natural gas in Great Lakes’ pipeline, causing the natural gas to flow to the next compressor station. DATES: During the public comment period, which ended August 24, 2009, EPA received timely written comments from Great Lakes Gas on the draft Title V permit. EPA responded to these comments and issued the final permit on October 2, 2009. No one appealed the final permit to the Environmental Appeals Board, therefore, in accordance with 40 CFR 71.11(i)(2), the final permit became effective 30 days after issuance, on November 2, 2009. ADDRESSES: The final signed permit and the response to comment document is available for public inspection online at https://yosemite.epa.gov/r5/r5ard.nsf/ Tribal+Permits!OpenView, or during normal business hours at the following address: EPA, Region 5, 77 West Jackson Boulevard (AR–18J), Chicago, Illinois 60604. FOR FURTHER INFORMATION CONTACT: Genevieve Damico, Environmental Engineer, EPA, Region 5, 77 West Jackson Boulevard (AR–18J), Chicago, Illinois 60604, (312) 353–4761, or damico.genevieve@epa.gov. SUPPLEMENTARY INFORMATION: This supplemental information is organized as follows: A. What is the Background Information? B. What is the Purpose of This Notice? A. What is the Background Information? Great Lakes Gas operates nearly 2,000 miles of large diameter underground PO 00000 Frm 00032 Fmt 4703 Sfmt 4703 68059 pipeline, which transports natural gas for delivery to customers in the midwestern and northeastern United States and eastern Canada. The Great Lakes pipeline system and other interstate natural gas transmission pipelines make up the long-distance link between natural gas production fields, local distribution companies, and end users. The pipeline’s 14 compressor stations, located approximately 75 miles apart, operate to keep natural gas moving through the system. Compressors at these stations add pressure to natural gas in the pipeline, causing it to flow to the next compressor station. The pipeline normally operates continuously, but at varying load, 24 hours per day and 365 days per year. CS#4 currently consists of two stationary natural gas-fired turbines, which in turn drive two natural gas compressors. Additionally, one natural gas-fired standby electrical generator provides electrical power for critical operations during temporary electrical power outages and during peak loading. CS#4 is located approximately 3 miles west of the City of Deer River, in Itasca County, Minnesota. The area is designated attainment for all criteria pollutants. CS#4, which occupies an area of approximately 20 acres, is owned and maintained by Great Lakes Gas on privately-owned fee land within the exterior boundaries of the Leech Lake Band of Ojibwe Indian Reservation. EPA is responsible for issuing and enforcing any air quality permits for the source until such time that the Tribe has EPA approval to do so. CS#4 is subject to Title V because it has the potential to emit greater than 100 tons per year of nitrogen oxide and carbon monoxide. Great Lakes Gas submitted to EPA on February 25, 2009, a Title V permit application to renew its 2004 Title V operating permit for CS#4. On July 23, 2009, EPA published a draft Title V permit to operate for public comment. The public comment period ended on August 24, 2009. We received written comments from Great Lakes Gas on the permit. EPA responded to these comments and issued the final permit on October 2, 2009. No one appealed the final permit to the Environmental Appeals Board, therefore, in accordance with 40 CFR 71.11(i)(2), this permit became effective 30 days after issuance, on November 2, 2009. EPA is not aware of any outstanding enforcement actions against Great Lakes Gas and believes the issuance of this permit is non-controversial. E:\FR\FM\22DEN1.SGM 22DEN1
