40 CFR Part 52

[EPA-R05-OAR-2006-0772; FRL-8439-7]

 
Approval and Promulgation of Air Quality Implementation Plans; 
Minnesota

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: EPA is approving revisions to the Minnesota State 
Implementation Plan (SIP) for sulfur dioxide (SO2). 
Specifically, the revisions involve Flint Hills Resources, L.P. (Flint 
Hills) of Dakota County, Minnesota. In these revisions, Flint Hills is 
expanding operations at its petroleum refinery. To account for the 
increased SO2 emissions from the expansion, Flint Hills is 
closing its sulfuric acid plant. An analysis of the revisions shows 
that air quality in the area will be protected after the modifications 
are made at the facility. Minnesota has also included additional 
monitoring requirements in the revisions. EPA proposed approval of this 
revision on April 9, 2007. One comment was received on the proposed 
rule, but the comment did not involve the proposed revision. The 
comment is addressed in this action.

DATES: This final rule is effective on August 20, 2007.

ADDRESSES: EPA has established a docket for this action under Docket ID 
No. EPA-R05-OAR-2006-0772. All documents in the docket are listed on

I. What Is the Background for This Action?

    Flint Hills operates a petroleum refinery in the Minneapolis-Saint 
Paul metropolitan area. Flint Hills is expanding its crude oil 
processing operations. The expansion will increase the crude oil unit's 
gasoline production capacity from 100,000 to 150,000 barrels per day. 
Minnesota amended its Findings and Order to allow the revisions 
necessary for the expansion. This is the eighth amendment to the Flint 
Hills Findings and Order.
    Minnesota held a public hearing regarding Findings and Order 
Amendment Eight on May 25, 2006. No comments on the Flint Hills 
revisions were received at the public meeting or during the 30 day 
public comment period.
    EPA proposed approval of the SIP revision on April 9, 2007 (72 FR 
17461-63). The comment period closed on May 9, 2007. One comment from 
the Minnesota Pollution Control Agency (PCA) was received. It is 
addressed in Section III.

II. What Is EPA's Analysis of the State Submission?

    Minnesota included air dispersion modeling results in its 
submission. The modeling analysis includes all Flint Hills SO2 
emissions sources, including the additional and modified sources. Other 
significant SO2 sources in the area were also included. The 
modeling analysis examined the impact of the revisions on the SO2 
air quality standards. The primary SO2 National Ambient Air 
Quality Standard (NAAQS) has both an annual and 24-hour averaging 
period. The secondary NAAQS has a 3-hour averaging period.
    Flint Hills used the ISCST3 dispersion model in the regulatory 
mode. Five years of surface meteorological data from the Minneapolis-
Saint Paul International Airport and upper air data from Saint Cloud 
were used. Building downwash effects from the new and existing 
structures were accounted for in the modeling. The analysis found that 
the predicted annual SO2 concentration is 38.5 [mu]g/m\3\ 
compared to the standard of 80 [mu]g/m\3\. The modeled 24-hour level of 
266.8 [mu]g/m\3\ is under the 365 [mu]g/m\3\ NAAQS. Similarly, the 
predicted 3-hour average is 726.2 [mu]g/m\3\ which is under the 
secondary standard of 1300 [mu]g/m\3\.

III. What Comments Were Received?

    One comment from the Minnesota PCA was received during the comment 
period. Minnesota PCA requested EPA to rescind the Administrative Order 
which established emission limits at the Continental Nitrogen & 
Resource Corporation (Continental Nitrogen) facility. Information on 
this company's removal of its boilers was included in the Flint Hills 
submission. Minnesota PCA has requested that EPA rescind the 
Administrative Order for the Continental Nitrogen boilers. EPA will 
address this request in a separate action.
    The comment does not involve the proposed revisions to the emission 
limits for Flint Hills. The outcome of the requested revision for 
Continental Nitrogen will not affect the Flint Hills revision because 
the Continental Nitrogen boilers are permanently disconnected. The 
emissions reduction from Continental Nitrogen has already occurred and 
is not dependent on EPA action.

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.
    The expansion of the Flint Hills facility includes an additional 
unit and revised limits on several units at the refinery that result in 
higher SO2 emissions. The projected increase in SO2 
emissions from this project is 315 tons per year. However, overall 
SO2 emissions from Flint Hills will be reduced after the 
modifications. When considering all sources at the facility there is no 
increase in SO2 emissions, in fact there is a projected 
decrease of 99.6 tons per year. Therefore, the ``net emissions 
increase'' is below the Prevention of Significant Deterioration (PSD) 
significant threshold for SO2 of 40 tons per year. This 
project is not subject to PSD requirements.
    The effects of the expansion were analyzed. Both the projected 
SO2 emissions from the Flint Hills facility and the 
reductions from other area facilities were considered. That analysis 
showed that the maximum predicted ambient SO2 concentrations 
are below the primary and secondary NAAQS. This indicates that public 
health and welfare in Dakota County, Minnesota will be protected. The 
additional monitoring requirements placed on the heater combusting the 
fuel gas from the 45 mix drum will also help protect the air quality by 
continuously checking the sulfur dioxide emissions from this unit. 
Corrective action can be taken should the emissions rise above the 
unit's limit.

V. What Action Is EPA Taking Today?

    EPA is approving revisions to SO2 emissions regulations 
for Flint Hills Resources, L.P. of Dakota County, Minnesota. The 
revisions authorize adding a new heater, modifying two heaters, and 
additional monitoring requirements.

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 Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use

    Because it is not a ``significant regulatory action'' under 
Executive Order 12866 or a ``significant regulatory 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

[[Page 39570]]

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 (65 
FR 67249, 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 Clean Air Act. 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 Clean Air Act. 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. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2).
    Under Section 307(b)(1) of the Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by September 17, 2007. 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).)
