I. What Actions Is EPA Taking?
EPA is taking final action to change the legal designation of the
Christian County, Kentucky, portion of the Clarksville-Hopkinsville 8-
hour ozone nonattainment area from nonattainment to attainment for the
8-hour ozone NAAQS. The interstate Clarksville-Hopkinsville 8-hour
ozone nonattainment area is composed of two counties (i.e., Christian
County, Kentucky, and Montgomery County, Tennessee). EPA is also
approving Kentucky's 8-hour ozone maintenance plan for Christian County
(such approval being one of the Clean Air Act (CAA) criteria for
redesignation to attainment status). The maintenance plan is designed
to help keep the Clarksville-Hopkinsville area (of which Christian
County is a part) in attainment for the 8-hour ozone NAAQS for the next
12 years. These approval actions are based on EPA's determination that
the Commonwealth of Kentucky has demonstrated that Christian County,
Kentucky, has met the criteria for redesignation to attainment
specified in the CAA, and that the entire Clarksville-Hopkinsville 8-
hour ozone nonattainment area has attained the 8-hour ozone standard.
EPA's analyses for Christian County, Kentucky, and Montgomery County,
Tennessee, are described in detail in the direct final rules published
September 22, 2005, at 70 FR 55550 and 70 FR 55559, respectively.
EPA is also providing information on the status of the Agency's
transportation conformity adequacy determination for the new MVEBs for
the years 2004 and 2016 that are contained in the maintenance plan for
Christian County, Kentucky. The maintenance plan establishes MVEBs for
the years 2004 and 2016, respectively, of 3.83 tons per day (tpd) and
2.08 tpd for volatile organic compound (VOC) emissions, and 9.53 tpd
and 3.83 tpd for nitrogen oxides (NOX). Through this action,
EPA is announcing that these MVEBs are adequate for the purposes of
transportation conformity. During EPA's Adequacy public comment period
which began on March 29, 2005, and closed on April 28, 2005, EPA did
not receive any adverse comments related to the MVEBs. EPA is also
approving these MVEBs in this action. Upon the publication of this
final rulemaking in the Federal Register, these MVEBs must be used by
the transportation partners in this area for future conformity
determinations. Additionally, conformity to these new MVEBs must be
demonstrated within 24 months of the effective date of this action,
pursuant to section 6011(a) of the Safe, Accountable, Flexible,
Efficient Transportation Equity Act--A Legacy for Users, which was
signed into law on August 10, 2005.
Additionally, in this action, EPA is responding to the adverse
comment received on the September 22, 2005, rulemaking proposing to
approve the aforementioned revisions (70 FR 55613).
II. What Is the Background for the Actions?
In two separate actions published on September 22, 2005, EPA
proposed to approve the redesignation of the Kentucky (70 FR 55613) and
Tennessee (70 FR 55613) portions of the Clarksville-Hopkinsville 8-Hour
Ozone Nonattainment Area to attainment. Also on that date, EPA
published two companion direct final rules approving the redesignation
to attainment of the Kentucky (70 FR 55550) and Tennessee (70 FR 55559)
portions of the nonattainment area. The proposed and direct final rules
stated that if EPA received adverse comment by October 24, 2005, the
direct final rule would be withdrawn and would not take effect. EPA
subsequently received an adverse comment regarding the redesignation of
the Kentucky portion of the nonattainment area (i.e., Christian
County). In this action, EPA is addressing the comment and taking final
action as described in section I and section IV.
[[Page 4048]]
III. Response to Comments
The following is a summary of the adverse comment received on the
proposed rule published September 22, 2005, (70 FR 55613) and EPA's
response to the comment.
Comment: The commenter asserts that the Kentucky Division for Air
Quality (KDAQ) has permitted a new source of NOX in
Muhlenberg County, Kentucky, which borders Christian County. The
commenter states that the source is permitted to emit well over 5,000
tons per year of NOX. The commenter asserts that until KDAQ
establishes that Christian County will be in attainment with the 8-hour
ozone NAAQS with the additional NOX emissions from this
source through a reasonable worst case analysis of the source's
NOX emissions during any one-hour or eight-hour hour period,
EPA should not redesignate Christian County to attainment.
Response: As detailed in Section III of the September 22, 2005,
direct final rule (70 FR 55550), the CAA provides the requirements for
redesignating a nonattainment area to attainment. Specifically, section
107(d)(3)(E) allows for redesignation providing that: (1) The
Administrator determines that the area has attained the applicable
NAAQS; (2) the Administrator has fully approved the applicable
implementation plan for the area under section 110(k); (3) the
Administrator determines that the improvement in air quality is due to
permanent and enforceable reductions in emissions resulting from
implementation of the applicable SIP and applicable Federal air
pollutant control regulations and other permanent and enforceable
reductions; (4) the Administrator has fully approved a maintenance plan
for the area as meeting the requirements of section 175A; and, (5) the
State containing such area has met all requirements applicable to the
area under section 110 and part D. EPA has determined that all of the
redesignation requirements are met for the Christian County area as
described in the September 22, 2005, rulemaking (70 FR 55550).
KDAQ has demonstrated that ozone precursor emissions inside the
Christian County nonattainment area will remain at or below attainment
year levels in the future, which indicate the 8-hour ozone standard
will be maintained. Furthermore, as for the impact of emissions outside
of Christian County, the commenter has provided no analysis indicating
that any such emissions would be likely to cause or contribute to
violations in the future. Kentucky had performed a cumulative
assessment of the impacts of current and proposed Kentucky electric
power generating facilities, and concluded that 8-hour ozone violations
are not likely to occur as a consequence of these emissions. The Agency
reviewed this report in response to the commenter's concerns. The
report, ``A Cumulative Assessment of the Environmental Impacts Caused
by Kentucky Electric Generating Units,'' dated December 17, 2001, is
included in the docket for this action. The report documents Kentucky's
analysis of the environmental impacts of 34 existing power plants and
22 proposed new or expanded power plants, including the proposed new
source in Muhlenberg County. Specific to air quality, the report
provides information on the changes in ozone and fine particulates
concentrations with the addition of these 56 proposed and existing
power plants in Kentucky. The emissions modeled for the proposed new
power plant in Muhlenberg County were: 507.4 tons per year (tpy) of
VOCs and 6,030 tpy of NOX. The impact assessment did not
identify potential ozone attainment problems for Christian County,
Kentucky, even though it considered far more sources than only the one
mentioned by the commenter.
Furthermore, EPA notes that NOX emissions from the
proposed power plant in Muhlenberg County will be subject to the
regional NOX reduction programs of the NOX SIP
Call and, in the future, the Clean Air Interstate Rule (CAIR) (70 FR
25162 (May 12, 2005)). Since Kentucky is regulated by those programs,
sources subject to them, including power plants, will remain subject to
an overall NOX emissions budget for the state that will not
increase as a result of the possible new plant in Muhlenberg County.
Consequently, that source would have to obtain NOX
allowances from other sources subject to the NOX SIP Call
and/or CAIR to emit NOX and the sources in the Commonwealth
of Kentucky would remain subject to the same overall NOX
budget.
The proposed new power plant in Muhlenberg County refers to the
Thoroughbred Generating Station (TGS) project. This project is proposed
to consist of two pulverized coal electric utility steam generating
units with a nominal power generating capacity of 750 megawatts each
and a nominal rated capacity heat input rate of 7,443 pounds per
million British thermal units (lb/MMBtu) each. The NOX and
VOC emissions limits for the two pulverized coal combustion units are
proposed to be as follows: 0.08 lb/MMBtu of NOX each
(equivalent to 5,216 tons per year for both units combined) and 0.0072
lb/MMBtu of VOCs each (equivalent to 235 tons per year for both units
combined). The KDAQ has a merged air emissions permitting program in
which a single permit serves as the prevention of significant
deterioration construction permit and the title V operating permit. The
merged permit was issued to Thoroughbred Generating Company, LLC (TGC)
on October 11, 2002, with slight revisions on December 6, 2002, and
February 17, 2005.
The permit issued to TGC was appealed through Kentucky's
administrative appeals procedure. The Administrative Hearing Officer
(AHO) issued a report with recommendations on August 9, 2005. The AHO
recommended remanding portions of the permit to the KDAQ. The Secretary
of the Kentucky Environmental and Public Protection Cabinet makes the
final determination on the appeal. No determination has yet been made
by the Secretary.
After KDAQ issued the original permit on October 11, 2002, EPA
received a petition to object to the title V portion of the permit. EPA
is awaiting the conclusion of the Kentucky permit appeal process before
completing a response to the petition. Thus the permit appeal process
for the source has not yet been concluded, and therefore the permit
provisions remain subject to revision. Moreover, EPA believes that for
the reasons set forth above that the TGS does not pose a potential
problem for attainment or maintenance of the standard in the
Clarksville-Hopkinsville area.
Should monitored violations of the 8-hour ozone NAAQS occur in
Christian County, the contingency plan within the County's 8-hour ozone
maintenance plan will be implemented to promptly correct the
violations. In the contingency measures section, Kentucky details
actions it will take if there are measured exceedances (i.e., an 8-hour
average equal to or greater than 0.085 parts per million) of the 8-hour
ozone standard, and reserves the right to implement other contingency
measures than those listed for the County if deemed necessary.
IV. Final Action
EPA is taking final action to change the legal designation of the
Christian County, Kentucky portion of the Clarksville-Hopkinsville 8-
hour ozone nonattainment area from nonattainment to attainment for the
8-hour ozone NAAQS. Through this action, EPA is announcing that the new
2004 and 2016 MVEBs are adequate for transportation conformity
purposes. EPA is also approving into the Kentucky SIP the 8-hour ozone
maintenance plan for
[[Page 4049]]
Christian County, and the new MVEBs for the years 2004 and 2016,
respectively, of 3.83 tpd and 2.08 tpd for VOC, and 9.53 tpd and 3.83
tpd for NOX.
V. Statutory and Executive Order Reviews
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. For this
reason, 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). This action
merely approves state law as meeting Federal requirements and imposes
no additional requirements beyond those imposed by state law.
Redesignation of an area to attainment under section 107(d)(3)(E) of
the CAA does not impose any new requirements on small entities.
Redesignation is an action that affects the status of a geographical
area and does not impose any new regulatory requirements on sources.
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.). 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).
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 (65
FR 67249, November 9, 2000). 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 affects the status of a
geographical area, does not impose any new requirements on sources, or
allow a state to avoid adopting or implementing other requirements, and
does not alter the relationship or the distribution of power and
responsibilities established in the CAA. 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 is not economically significant, and because the Agency does not
have reason to believe that the rule concerns an environmental health
risk or safety risk that may disproportionately affect children.
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
Commonwealth 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. Redesignation is an
action that affects the status of a geographical area but does not
impose any new requirements on sources. 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. 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.).
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 CAA, petitions for judicial review
of this action must be filed in the United States Court of Appeals for
the appropriate circuit by March 27, 2006. 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).)
