Environmental Protection Agency (EPA).
Direct final rule.
EPA is approving State Implementation Plan (SIP) revisions to sulfur dioxide (SO2) requirements for Northern States Power Company, doing business as Xcel Energy, Inver Hills Generating Plant (Inver Hills), located in Inver Grove Heights, Dakota County, Minnesota. The revisions make the limits of the sulfur content in its fuel and its sulfur dioxide emissions more stringent, and prohibit the burning of residual fuel oil. The revisions allow the facility to use simpler methods to analyze the sulfur content of its fuel. Because the sulfur dioxide emission limits are being reduced, the air quality of Dakota County will be protected.
This direct final rule will be effective February 4, 2008, unless EPA receives adverse comments by January 4, 2008. If adverse comments are received, EPA will publish a timely withdrawal of the direct final rule in the Federal Register informing the public that the rule will not take effect.

Throughout this document whenever “we,” “us,” or “our” is used, we mean EPA. This supplementary information section is arranged as follows:
I. What is EPA Approving?
II. What is the Background for this Action?
III. What is EPA's Analysis of the State Submission?
IV. What are the Environmental Effects of this Action?
V. What Action is EPA Taking?
VI. Statutory and Executive Order Reviews
I. What is EPA Approving?
EPA is approving into the SO2 SIP for Minnesota revised conditions from the Inver Hills joint Title I/Title V document. The revisions lower the allowable sulfur content of its fuel and reduce the allowable limits of its SO2 emissions. The revisions also allow a simplified method to analyze fuel sulfur content. EPA is also removing from the SIP any non-SIP related Title I conditions that were previously mistakenly incorporated into the SIP for Inver Hills.
EPA is incorporating only the conditions in the joint Title I/Title V document labeled as “Title I Condition: State Implementation Plan for SO2 NAAQS” into the Minnesota SIP. The joint Title I/Title V document is the Minnesota Air Emission Permit Number 03700015-003.
II. What is the Background for This Action?
A. What are the Revisions to the SIP?
Xcel Energy's Inver Hills facility is a 440 Megawatt peak demand electrical generation plant. The plant has six generation units, turbines EU 001-EU 006, which can fire both natural gas and distillate fuel oil. The facility is located in the Pine Bend portion of the Minneapolis-Saint Paul SO2 maintenance area.
The SIP revisions reduce the limit for SO2 emissions from the six turbines from 0.67 pounds per million British Thermal Units (lb/MMBTU) to 0.50 lb/MMBTU. This emission reduction is achieved by requiring the reduction of the sulfur content in the fuel from 0.64 percent by weight to 0.48 percent by weight. The SIP revision prohibits the use of residual fuel oil. If Inver Hills uses low sulfur fuel having a sulfur content of 0.10 percent by weight or less, Inver Hills can use a guarantee from a supplier as to the sulfur content of the fuel, and can use a simple fuel analysis option (ASTM Method D-1552) at the time of delivery.
B. What Prior SIP Actions Are Pertinent to This Action?
In 1980, Inver Hills was identified by the state of Minnesota as a culpable source in the Pine Bend area's nonattainment plan for the SO2 National Ambient Air Quality Standards (NAAQS). On July 28, 1992, the Minnesota Pollution Control Agency (MPCA) issued an Administrative Order for Inver Hills to address the source's contribution to the nonattainment problem. The SIP revision contained in the Administrative Order was approved by EPA into the SIP on April 14, 1994. The most recent SIP action was taken when the MPCA submitted the Title I SIP conditions in the original Title V permit, Air Emission Permit 03700015-001, to EPA in August 2002. EPA approved those Title I SIP conditions into the SIP as of July 2, 2004 (69 FR 31891). However, the materials incorporated by reference into the SIP included all Title I conditions, including certain conditions that were unrelated to the SIP.
C. Has Public Notice Been Provided?
Minnesota published public notice of the Inver Hills revisions on September 7, 2006. No comments were received during the comment period which ended on October 9, 2006. In the public notice, Minnesota stated it would hold a public hearing if one were requested during the comment period. This follows the alternative public participation process EPA approved on June 5, 2006 (71 FR 32274). For limited types of SIP revisions that the public has shown little interest in, a public hearing is not automatically required. If anyone requests a public hearing during the comment period, Minnesota will hold a public hearing. Because no one requested a public hearing, Minnesota did not hold a public hearing for this SIP revision.
D. What Are Title I Conditions and Joint Title I/Title V Documents?
SIP control measures were contained in permits issued to culpable sources in Minnesota until 1990 when EPA determined that limits in state-issued permits are not federally enforceable because the permits expire. Minnesota then issued permanent Administrative Orders to culpable sources in nonattainment areas from 1991 to February of 1996.
Minnesota's consolidated permitting regulations, approved into the state SIP on May 2, 1995 (60 FR 21447), includes the term “Title I condition” which was written, in part, to satisfy EPA requirements that SIP control measures remain permanent. A “Title I condition” is defined as “any condition based on source-specific determination of ambient impacts imposed for the purposes of achieving or maintaining attainment with the national ambient air quality standard and which was part of the state implementation plan approved by EPA or submitted to the EPA pending approval under section 110 of the act * * *” The rule also states that “Title I conditions and the permittee's obligation to comply with them, shall not expire, regardless of the expiration of the other conditions of the permit.” Further, “any Title I condition shall remain in effect without regard to permit expiration or reissuance, and shall be restated in the reissued permit.”
Minnesota has initiated using joint Title I/Title V documents as the enforceable document for imposing emission limitations and compliance requirements in SIPs. The SIP requirements in joint Title I/Title V documents submitted by MPCA are cited as “Title I conditions,” therefore ensuring that SIP requirements remain permanent and enforceable. EPA reviewed the State's procedure for using joint Title I/Title V documents to implement site-specific SIP requirements and found it to be acceptable under both Titles I and V of the Act (July 3, 1997 letter from David Kee, EPA, to Michael J. Sandusky, MPCA). Further, a June 15, 2006, letter from EPA to MPCA clarifies procedures to transfer requirements from Administrative Orders to joint Title I/Title V documents.
III. What Is EPA's Analysis of the State Submission?
Xcel Energy is receiving more stringent SO2 limits on the generation units at the Inver Hills facility. However, it can take advantage of simplified methods of meeting fuel sulfur content and analysis requirements. The use of low sulfur fuel will ensure the tightened emission limits are met.
A modeling analysis was not conducted for the Inver Hills revision because its emission limits will be more stringent. The actual emissions may not decrease, but the potential to emit will decrease with the SO2 limit reductions. Start Printed Page 68510Modeling uses potential to emit in determining the impact on ambient air. Minnesota has noted that a July 2006 modeling analysis for the Pine Bend area showed that ambient SO2 levels will remain below the standards and thus the area's air quality is protected. All significant sources of SO2 emissions in the Pine Bend area including Inver Hills were in the July 2006 modeling analysis.
IV. What Are the Environmental Effects of This Action?
Sulfur dioxide causes breathing difficulties and aggravation of existing cardiovascular disease. It is also a precursor of acid rain and fine particulate matter formation. Sulfate particles are a major cause of visibility impairment in America. Acid rain damages lakes and streams impairing aquatic life and causes damage to buildings, sculptures, statues, and monuments. Sulfur dioxide also causes the loss of chloroform leading to vegetation damage. Ambient SO2 levels are expected to be unchanged or to decrease because of the SIP revisions. Thus, the Pine Bend area of Dakota County, Minnesota is expected to remain in attainment of the SO2 NAAQS.
V. What Action Is EPA Taking?
EPA is approving into the Minnesota SIP revised Title I conditions from the Inver Hills joint Title I/Title V document. EPA is also removing from the SIP for Inver Hills any non-SIP related Title I conditions that were previously mistakenly incorporated into the SIP.
We are publishing this action without prior proposal because we view this as a noncontroversial amendment and anticipate no adverse comments. However, in the proposed rules section of this Federal Register publication, we are publishing a separate document that will serve as the proposal to approve the state plan if relevant adverse written comments are filed. This rule will be effective February 4, 2008 without further notice unless we receive relevant adverse written comments by January 4, 2008. If we receive such comments, we will withdraw this action before the effective date by publishing a subsequent document that will withdraw the final action. All public comments received will then be addressed in a subsequent final rule based on the proposed action. The EPA will not institute a second comment period. Any parties interested in commenting on this action should do so at this time. If we do not receive any comments, this action will be effective February 4, 2008.
VI. Statutory and Executive Order Reviews
Executive Order 12866: Regulatory Planning and Review
Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is not a “significant regulatory action” and, therefore, is not subject to review by the Office of Management and Budget.
Executive Order 13211: Actions That Significantly Affect Energy Supply, Distribution, or Use
Because it is not a “significant regulatory action” under Executive Order 12866 or a “significant energy action,” this action is also not subject to Executive Order 13211, “Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use” (66 FR 28355, May 22, 2001).
Regulatory Flexibility Act
This action merely approves state law as meeting Federal requirements and imposes no additional requirements beyond those imposed by state law. Accordingly, the Administrator certifies that this rule will not have a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.).
Unfunded Mandates Reform Act
Because this rule approves pre-existing requirements under state law and does not impose any additional enforceable duty beyond that required by State law, it does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4).
Executive Order 13175: Consultation and Coordination With Indian Tribal Governments
This rule also does not have tribal implications because it will not have a substantial direct effect on one or more Indian tribes, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified by Executive Order 13175 (59 FR 22951, November 9, 2000).
Executive Order 13132: Federalism
This action also does not have Federalism implications because it does not have substantial direct effects on the states, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132 (64 FR 43255, August 10, 1999). This action merely approves a State rule implementing a Federal standard, and does not alter the relationship or the distribution of power and responsibilities established in the Clean Air Act.
Executive Order 13045: Protection of Children From Environmental Health and Safety Risks
This rule also is not subject to Executive Order 13045 “Protection of Children from Environmental Health Risks and Safety Risks” (62 FR 19885, April 23, 1997), because it approves a State rule implementing a Federal Standard.
National Technology Transfer Advancement Act
In reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the CAA. In this context, in the absence of a prior existing requirement for the state to use voluntary consensus standards (VCS), EPA has no authority to disapprove a SIP submission for failure to use VCS. It would thus be inconsistent with applicable law for EPA, when it reviews a SIP submission, to use VCS in place of a SIP submission that otherwise satisfies the provisions of the CAA. Thus, the requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) do not apply.
Paperwork Reduction Act
This rule does not impose an information collection burden under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).
Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register. Start Printed Page 68511This action is not a “major rule” as defined by 5 U.S.C. 804(2).
Under section 307(b)(1) of the CAA, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by February 4, 2008. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this rule for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)Start List of Subjects
