[EPA-R06-OAR-2007-0886; FRL-8473-3]
Approval and Promulgation of Implementation Plans; Arkansas;
Clean Air Interstate Rule Nitrogen Oxides Ozone Season Trading Program
AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: EPA is taking a direct final action to approve a revision to
the Arkansas State Implementation Plan (SIP) submitted on August 10,
2007, enacted at Regulation 19--Arkansas Plan of Implementation for Air
Pollution Control; Chapter 14, Sections 19.1401-19.1404; and Chapter
15, Section 19.1501. This revision addresses the requirements of EPA's
Clean Air Interstate Rule (CAIR) Nitrogen Oxides (NOX) Ozone
Season Trading Program, promulgated on May 12, 2005 and subsequently
revised on April 28 and December 13, 2006. EPA is approving the SIP
revision as fully implementing the CAIR NOX ozone season
requirements for Arkansas. Therefore, as a consequence of this SIP
approval, EPA will also withdraw the CAIR Federal Implementation Plan
(CAIR FIP) concerning NOX ozone season emissions for
Arkansas. The CAIR FIPs for all States in the CAIR region were
promulgated on April 28, 2006 and subsequently revised on December 13,
2006.
The intended effect of this action is to reduce NOX
emissions from the State of Arkansas that are contributing to
nonattainment of the 8-hour ozone National Ambient Air Quality Standard
(NAAQS or standard) in downwind states. This action is being taken
under section 110 of the Federal Clean Air Act (the Act or CAA).
DATES: This rule is effective on November 26, 2007 without further
notice, unless EPA receives relevant adverse comment by October 26,
2007. If EPA receives such comment, EPA will publish a timely
withdrawal in the Federal Register informing the public that this rule
will not take effect.

I. What Action Is EPA Taking?
EPA is taking direct final action to approve a revision to
Arkansas's SIP, submitted on August 10, 2007, enacted at Regulation
19--Arkansas Plan of Implementation for Air Pollution Control; Chapter
14, Sections 19.1401-19.1404; and Chapter 15, Section 19.1501. In its
SIP revision, Arkansas would meet CAIR NOX ozone season
requirements by requiring certain electric generating units (EGUs) to
participate in the EPA-administered CAIR cap-and-trade program
addressing NOX ozone season emissions. The SIP as revised
that EPA is approving meets the applicable requirements of CAIR. Our
detailed analysis of this SIP revision is in the Technical Support
Document (TSD) for the Arkansas CAIR NOX Ozone Season
Trading Program. The TSD is available as specified in the section of
this document identified as ADDRESSES. As a consequence of the SIP
approval, the Administrator of EPA will also issue a final rule to
withdraw the FIP concerning NOX ozone season emissions for
Arkansas. This action will delete and reserve 40 CFR 52.184 in part 52.
The withdrawal of the CAIR FIP for Arkansas is a conforming amendment
that must be made once the SIP is approved because EPA's authority to
issue the FIP was premised on a deficiency in the SIP for Arkansas.
Once the SIP is fully approved, EPA no longer has authority for the FIP
since the deficiency has been corrected. Thus, EPA will not have the
option of maintaining the FIP following the full SIP approval.
Accordingly, EPA does not intend to offer an opportunity for a public
hearing or an additional opportunity for written public comment on the
withdrawal of the FIP.
We are publishing this rule without prior proposal because we view
this as a noncontroversial amendment and anticipate no relevant 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 SIP revision if relevant adverse
comments are received. This rule will be effective on November 26, 2007
without further notice unless we receive relevant adverse comment by
October 26, 2007. If we receive relevant adverse comments, we will
publish a timely withdrawal in the Federal Register informing the
public that the rule will not take effect. We will address all public
comments in a subsequent final rule based on the proposed rule. We will
not institute a second comment period on this action. Any parties
interested in commenting must do so now. Please note that if we receive
adverse comment on an amendment, paragraph, or section of this rule and
if that provision may be severed from the remainder of the rule, we may
adopt as final those provisions of the rule that are not the subject of
an adverse comment.
II. What Is the Regulatory History of CAIR and the CAIR FIPs?
The Clean Air Interstate Rule (CAIR) was published by EPA on May
12, 2005 (70 FR 25162). In this rule, EPA determined that 28 States and
the District of Columbia contribute significantly to nonattainment and
interfere with maintenance of the national ambient air quality
standards (NAAQS) for fine particles (PM2.5) and /or 8-hour
ozone in downwind States in the eastern part of the country. As a
result, EPA required those upwind States to revise their SIPs to
include control measures that reduce emissions of SO2, which
is a precursor to PM2.5 formation, and/or NOX,
which is a precursor to both ozone and PM2.5 formation. For
jurisdictions that contribute significantly to downwind
PM2.5 nonattainment, CAIR sets annual State-wide emission
reduction requirements (i.e., budgets) for SO2 and annual
State-wide emission reduction requirements for NOX.
Similarly, for jurisdictions that contribute significantly to 8-hour
ozone nonattainment, CAIR sets State-wide emission reduction
requirements for NOX for the ozone season (defined at 40 CFR
97.302 as May 1st to September 30th). Under CAIR, States may implement
these reduction requirements by participating in the EPA-administered
cap-and-trade programs or by adopting any other control measures.
Arkansas was found to significantly contribute to nonattainment of the
8-hour ozone standard in Texas, resulting in Arkansas being subject to
the NOX ozone season CAIR requirements.
CAIR explains to subject States what must be included in SIPs to
address the requirements of section 110(a)(2)(D) of the Clean Air Act
(CAA) with regard to interstate transport with respect to the 8-hour
ozone and PM2.5 NAAQS. EPA made national findings, effective
on May 25, 2005, that the States had failed to submit SIPs meeting the
requirements of section 110(a)(2)(D). The SIPs were due in July 2000, 3
years after the promulgation of the 8-hour ozone and PM2.5
NAAQS. These findings started a 2-year clock for EPA to promulgate a
Federal Implementation Plan (FIP) to address the requirements of
section 110(a)(2)(D). Under CAA section 110(c)(1), EPA may issue a FIP
anytime after such findings are made and must do so within two years
unless a SIP revision correcting the deficiency is approved by EPA
before the FIP is promulgated.
On April 28, 2006, EPA promulgated CAIR FIPs for all States covered
by CAIR in order to ensure the emissions reductions required by CAIR
are achieved on schedule (71 FR 25328). See 40 CFR 52.35 and 52.36.
Each CAIR State is subject to the FIP until the State fully adopts, and
EPA approves, a SIP revision meeting the requirements of CAIR. The CAIR
FIPs require certain EGUs to participate in the EPA-administered CAIR
SO2, NOX annual, and NOX ozone season
trading programs, as appropriate, found at 40 CFR part 97. The CAIR FIP
SO2, NOX annual, and NOX ozone season
trading programs impose essentially the same requirements as, and are
integrated with, the respective CAIR SIP trading programs. The
integration of the CAIR FIP and SIP trading programs means that these
trading programs will work together to create effectively a single
trading program for each regulated pollutant (SO2,
NOX annual, and NOX ozone season) in all States
covered by the CAIR FIP or SIP trading program for that pollutant. The
CAIR FIPs also allow States to submit abbreviated SIP revisions that,
if approved by EPA, will automatically replace or supplement certain
CAIR FIP provisions, while the CAIR FIPs remain in place for all other
provisions.
On April 28, 2006, EPA published two additional CAIR-related final
rules that added the States of Delaware and New Jersey to the list of
States subject to CAIR for PM2.5 and announced EPA's final
decisions on reconsideration of five issues, without making any
substantive changes to the CAIR requirements (71 FR 25288 and 71 FR
25304, respectively). On December 13, 2006, EPA published minor, non-
substantive revisions that serve to clarify the CAIR and CAIR FIP
regulations (71 FR 74792).
III. What Are the General Requirements of CAIR and the CAIR FIPs?
CAIR establishes State-wide emission budgets for SO2 and
NOX and is to be implemented in two phases. The first phase
of NOX reductions starts in 2009 and continues through 2014,
while the
[[Page 54558]]
first phase of SO2 reductions starts in 2010 and continues
through 2014. The second phase of reductions for both NOX
and SO2 starts in 2015 and continues thereafter. CAIR
requires States to implement the budgets by either: (1) Requiring EGUs
to participate in the EPA-administered cap-and-trade programs; or (2)
adopting other control measures of the State's choosing and
demonstrating that such control measures will result in compliance with
the applicable State SO2 and NOX budgets.
The May 12, 2005 and April 28, 2006 CAIR rules provide model rules
that States must adopt (with certain limited changes, if desired) if
they want to participate in the EPA-administered trading programs. The
December 13, 2006, revisions to the CAIR and CAIR FIP regulations were
non-substantive and, therefore, do not affect EPA's evaluation of a
State's SIP revision.
With two exceptions, only States that choose to meet the
requirements of CAIR through methods that exclusively regulate EGUs are
allowed to participate in the EPA-administered trading programs. One
exception is for States that adopt the opt-in provisions of the model
rules to allow non-EGUs individually to opt into the EPA-administered
trading programs. The other exception is for States that include all
non-EGUs from their NOX SIP Call trading programs in their
CAIR NOX ozone season trading programs. Arkansas was not
subject to the NOX SIP Call requirements; therefore this
exception is not available to the State.
IV. What Are the Types of CAIR SIP Submittals?
States have the flexibility to choose the type of control measures
they will use to meet the requirements of CAIR. EPA anticipates that
most States will choose to meet the CAIR requirements by selecting an
option that requires EGUs to participate in the EPA-administered CAIR
cap-and-trade programs. For such States, EPA has provided two
approaches for submitting and obtaining approval for CAIR SIP
revisions. States may submit full SIP revisions that adopt the model
CAIR cap-and-trade rules. If approved, these SIP revisions will fully
replace the State's CAIR FIPs. Alternatively, States may submit
abbreviated SIP revisions. The provisions in the abbreviated SIP
revision, if approved into a State's SIP, will not replace that State's
CAIR FIP; however, the requirements for the CAIR FIPs at 40 CFR part 52
incorporate the provisions of the Federal CAIR trading programs in 40
CFR part 97. The Federal CAIR trading programs in 40 CFR part 97
provide that whenever EPA approves an abbreviated SIP revision, the
provisions in the abbreviated SIP revision will be used in place of or
in conjunction with, as appropriate, the corresponding provisions in 40
CFR part 97 of the State's CAIR FIP.
A State submitting a full SIP revision may either adopt regulations
that are substantively identical to the model rules or incorporate by
reference the model rules. CAIR provides that States may only make
limited changes to the model rules if the States want to participate in
the EPA-administered trading programs. A full SIP revision may change
the model rules only by altering their applicability and allowance
allocation provisions to:
(1) Include NOX SIP Call trading sources that are not
EGUs under CAIR in the CAIR NOX Ozone Season Trading
Program;
(2) Provide for State allocation of NOX annual or ozone
season allowances using a methodology chosen by the State;
(3) Provide for State allocation of NOX annual
allowances from the compliance supplement pool (CSP) using the State's
choice of allowed, alternative methodologies; or
(4) Allow units that are not otherwise CAIR units to opt
individually into the CAIR SO2, NOX Annual, or
NOX Ozone Season Trading Programs under the opt-in
provisions in the model rules.
EPA's authority to issue the CAIR FIPs was premised on the deficiency
of each State's SIP in addressing the CAIR requirements. EPA will not
have the option of maintaining the CAIR FIP following approval of a
full CAIR SIP revision. Therefore, an approved CAIR full SIP revision
will replace the CAIR FIP requirements for NOX annual,
NOX ozone season, or SO2 emissions, as
applicable, for that State.
V. What Is EPA's Analysis of the Arkansas CAIR NOX Ozone
Season SIP Submittal?
A. State Budget for NOX Ozone Season Allowance Allocations
The CAIR NOX ozone season budgets for Arkansas were
developed from historical heat input data for EGUs. Using these data,
EPA calculated annual and ozone season regional heat input values,
which were multiplied by 0.15 lb/mmBtu, for phase 1, and 0.125 lb/
mmBtu, for phase 2, to obtain regional NOX budgets for 2009-
2014 and for 2015 and thereafter, respectively. EPA derived the
Arkansas NOX ozone season budgets from the regional budgets
using Arkansas heat input data adjusted by fuel factors.
The CAIR SIP requirements and the Arkansas CAIR NOX
ozone season FIP establish the NOX ozone season budgets for
Arkansas as 11,515 tons of NOX ozone season emissions for
2009-2014 and 9,596 tons of NOX ozone season emissions in
2015 and thereafter. Arkansas's rules at 19.1402 establish that the
total amount of NOX ozone season allowances allocated per
control period is as listed in 40 CFR 51.123 and 96.340; ensuring that
the Arkansas allocation methodology will not allocate more allowances
than the state NOX ozone season budget, consistent with 40
CFR 51.123.
B. CAIR NOX Ozone Season Cap-and-Trade Program
The CAIR NOX annual and ozone season FIPs for the States
largely mirror the structure of the NOX SIP Call model-
trading rule in 40 CFR part 96 subparts A through I. While the
provisions of the NOX annual and ozone season FIPs are
similar, there are some differences. For example, the NOX
Annual FIPs provide for a compliance supplement pool, under which
allowances may be awarded for early reductions of NOX annual
emissions.
EPA used the CAIR model trading rules as the basis for the
SO2, NOX annual, and NOX ozone season
trading programs incorporated by reference into the States' CAIR FIPs.
The CAIR FIP trading programs' rules are virtually identical to the
CAIR model trading rules, with changes made to account for federal
rather than state implementation. The CAIR model SO2,
NOX annual, and NOX ozone season trading rules
and the respective CAIR FIP trading programs are designed to work
together as integrated SO2, NOX annual, and
NOX ozone season trading programs.
In the August 10, 2007, SIP revision, Arkansas chose to implement
its CAIR NOX ozone season budgets by requiring EGUs to
participate in the EPA-administered cap-and-trade program for
NOX ozone season emissions. Arkansas has adopted a full SIP
revision that incorporates by reference the CAIR model cap-and-trade
rule for NOX ozone season emissions as published at 40 CFR
part 96, subparts AAAA-HHHH on May 12, 2005, and further revised on
April 28 and December 13, 2006. This SIP revision does not include
subpart IIII, CAIR NOX Ozone Season Opt-in Units, and any
references to opt-in units. This SIP revision provides an allowance
allocation methodology that replaces 40 CFR part 96, subpart EEEE.
[[Page 54559]]
C. Applicability Provisions for Non-EGU NOX SIP Call Sources
In general, the CAIR FIPs' trading programs apply to any
stationary, fossil-fuel-fired boiler or stationary, fossil-fuel-fired
combustion turbine serving at any time, since the later of November 15,
1990 or the start-up of the unit's combustion chamber, a generator with
nameplate capacity of more than 25 MWe producing electricity for sale.
Because Arkansas was not included in the NOX SIP Call
trading program, Arkansas does not have or need the option of expanding
the applicability provisions of the CAIR NOX Ozone Season
Trading Program to include non-EGU NOX SIP Call sources.
D. NOX Ozone Season Allowance Allocations
Under the NOX allowance allocation methodology in the
CAIR model trading rules and in the CAIR FIP NOX ozone
season trading programs, NOX ozone season allowances are
allocated to units that have operated for five years, based on heat
input data from a three-year period that are adjusted for fuel type by
using fuel factors of 1.0 for coal, 0.6 for oil, and 0.4 for other
fuels. The CAIR model trading rules and the CAIR FIP NOX
ozone season trading program also provide a new unit set-aside from
which units without five years of operation are allocated allowances
based on the units' prior year emissions.
The CAIR FIP provisions provide States with the flexibility to
establish a different NOX allowance allocation methodology
that will be used to allocate allowances to sources in a State if
certain requirements are met concerning the timing of submission of
units' allocations to the Administrator for recordation and the total
amount of allowances allocated for each control period. In adopting
alternative NOX allowance allocation methodologies, States
have flexibility with regard to:
(1) The cost to recipients of the allowances, which may be
distributed for free or auctioned;
(2) The frequency of allocations;
(3) The basis for allocating allowances, which may be distributed,
for example, based on historical heat input or electric and thermal
output; and
(4) The use of allowance set-asides and, if used, their size.
Consistent with the flexibility given to States in their CAIR FIP
provisions, Arkansas has chosen to replace the provisions of the
Arkansas CAIR NOX Ozone Season FIP concerning the allocation
of NOX ozone season allowances with its own methodology. To
address the concerns of interstate transport, the ADEQ initiated a
stakeholder process to work with affected industry and EPA Region 6. As
a result of the stakeholder process, ADEQ submitted a full CAIR
NOX Ozone Season SIP revision on August 10, 2007. Section
19.1401 incorporates by reference 40 CFR part 96, subparts AAAA-HHHH,
with the exception of EEEE, as promulgated by EPA on May 12, 2005, and
further revised on April 28 and December 13, 2006. Additionally,
section 19.1401 states that Subpart IIII and all references to opt-in
units are not incorporated into the Arkansas SIP. Sections 19.1402-
19.1404 of the Arkansas CAIR NOX Ozone Season Trading
Program SIP revision establish the NOX ozone season
allowance allocation methodology that is to be used in place of 40 CFR
part 96, subpart EEEE.
Section 19.1402 establishes that the Arkansas NOX Ozone
Season budget is 11,515 tons per control period from 2009-2014 and
9,596 tons per control period starting with the 2015 control period.
These budgets are as listed in 40 CFR 51.123(q)(2) (11,515 tons in
2009-2014 and 9,596 tons in 2015 and thereafter); ensuring that the
Arkansas allocation methodology will not allocate more allowances than
the state NOX ozone season budget.
Section 19.1403 establishes the dates by which the ADEQ must submit
NOX ozone season allocations to EPA for recordation in CAIR
compliance accounts. Section 19.1403 is divided further based on unit
operating history; 19.1403(A) provides the allowance allocation timing
for the EGUs with a baseline gross electric generation as defined in
19.1404(A), and 19.1403(B) provides the allowance allocation timing for
the EGUs without a baseline gross electric generation. No later than
April 30, 2007, the ADEQ will determine and submit to the EPA the CAIR
NOX ozone season allowances for the control periods 2009,
2010, and 2011, for EGUs with a baseline gross electric generation.
Additionally for the EGUs with a baseline gross electric generation,
the ADEQ will determine and submit to the EPA the CAIR NOX
ozone season allowances by October 31, 2008, for the year 2012, and by
October 31 of each year thereafter for the 4th year after the
notification deadline. For EGUs without a baseline gross electric
generation, the ADEQ will determine and submit to EPA the
NOX ozone season allowance allocations by July 31 of the
year for which the allowances are allocated.
Baseline gross electric generation is determined in accordance with
section 19.1404(A) for CAIR units that have operated each calendar year
during a period of five or more calendar years. The baseline gross
electric generation is the average of the three highest amounts of a
CAIR unit's control period gross electrical output over the five years
immediately preceding the year in which allocations are due to EPA. If
a generator is served by two or more units, the gross electrical output
of the generator will be apportioned to each unit based on the unit's
share of the total control period heat input for that year.
The ADEQ submitted a letter to the EPA dated June 7, 2007, to
further explain section 19.1404(A). Once a unit has operated for five
or more calendar years before the allocation submittal deadline and had
a calculable baseline gross electric generation, the unit cannot be
considered a non-baseline unit in the future. For example, if a unit
operated from 2000-2006, the unit would have a calculable baseline
gross electric generation used for the 2007, 2008, and 2009 control
period allocations. If the unit shutdown or suspended operations for
2007 and started operating again in 2008, the unit would still be
considered a baseline unit. The year 2007 would have zero electric
output recorded in the baseline calculation.
Section 19.1404(C) establishes the allocation methodology for CAIR
units with a baseline gross electric generation as calculated pursuant
to section 19.1404(A). For each control period, the ADEQ will allocate
to all units with a calculable baseline a total amount of allowances
equal to 95% of the total ozone season budget established in 19.1402.
These units will receive allowances proportional to their share of the
total baseline gross electric generation for all such units; i.e., the
ratio of the unit's baseline gross electric generation to the total
baseline gross electric generation multiplied by the total amount of
allowances allocated each control period to units with baseline data.
Section 19.1404(D) establishes the allocation methodology for CAIR
units without a calculable baseline. For these units, the ADEQ will
establish a new unit set-aside for each control period equal to 5% of
the total ozone season budget in section 19.1402. Starting with the
later of the 2009 control period or the first control period after the
control period in which the CAIR unit commences commercial operation,
the Designated Representative for the non-baseline units may submit a
request to the ADEQ for the set-aside allowances.
[[Page 54560]]
This request must be submitted to the ADEQ no later than January 1st of
the first control period in which the new unit set-aside allowances are
requested and after the date in which the new unit commences commercial
operation. The request for allowances may not exceed the unit's total
tons of NOX emissions during the previous control period.
On or after February 1st of each control period, the ADEQ will
determine the total amount of new unit set-aside allowances requested.
If the total amount of allowances requested is less than the total new
unit set-aside pool (5% of the overall state budget) the ADEQ will
allocate the new unit set-aside allowances as requested to each unit.
If the total amount of requested allowances is greater than the total
new unit set-aside pool, the ADEQ will determine the allocations by
multiplying the ratio of each unit's requested number of allowances to
the total amount of requested allowances by the new unit set-aside
amount. The ADEQ will then notify each unit's Designated Representative
of the amount of new unit set-aside allowances the unit will receive.
If there are allowances remaining in the new unit set-aside after
the non-baseline units receive their allocations, the ADEQ will
allocate these remaining allowances to units with baseline gross
electric generation. The ADEQ will multiply the remaining number of
allowances by the ratio of the baseline unit's allocation for that
control period to the total amount of allowances allocated to the
baseline units (95% of the overall state budget in section 19.1402).
Section 19.1501 establishes the effective date of the revision to
Regulation 19, Chapter 14, Sections 19.1401-19.1404 as ten days after
filing with the Arkansas Secretary of State, the Arkansas State
Library, and the Arkansas Bureau of Legislative Research.
E. Individual Opt-In Units
The opt-in provisions of the CAIR model trading rules allow certain
non-EGUs (i.e., boilers, combustion turbines, and other stationary
fossil-fuel-fired devices) that do not meet the applicability criteria
for a CAIR trading program to participate voluntarily in (i.e., opt
into) the CAIR trading program. A non-EGU may opt into one or more of
the CAIR trading programs. In order to qualify to opt into a CAIR
trading program, a unit must vent all emissions through a stack and be
able to meet monitoring, recordkeeping, and reporting requirements of
40 CFR part 75. The owners and operators seeking to opt a unit into a
CAIR trading program must apply for a CAIR opt-in permit. If the unit
is issued a CAIR opt-in permit, the unit becomes a CAIR unit, is
allocated allowances, and must meet the same allowance-holding and
emissions monitoring and reporting requirements as other units subject
to that CAIR trading program. The opt-in provisions provide for two
methodologies for allocating allowances for opt-in units, one
methodology that applies to opt-in units in general and a second
methodology that allocates allowances only to opt-in units that the
owners and operators intend to repower before January 1, 2015.
States have several options concerning the opt-in provisions.
States may adopt the CAIR opt-in provisions entirely or may adopt them
but exclude one of the methodologies for allocating allowances. States
may also decline to adopt the opt-in provisions.
Arkansas has chosen not to allow non-EGUs to opt into the CAIR
NOX Ozone Season Trading Program. Arkansas incorporated by
reference the CAIR NOX Ozone Season Trading Program,
published at 40 CFR part 96, subparts AAAA-HHHH on May 12, 2005, and
further revised on April 28 and December 13, 2006. This SIP revision
does not include subpart IIII, CAIR NOX Ozone Season Opt-in
Units, and any references to opt-in units.
VI. Final Action
We are approving Arkansas's CAIR NOX Ozone Season
Trading Program SIP revision submitted on August 10, 2007, enacted at
Regulation 19--Arkansas Plan of Implementation for Air Pollution
Control; Chapter 14, Sections 19.1401-19.1404; and Chapter 15, Section
19.1501. Under this SIP revision, Arkansas is choosing to participate
in the EPA-administered cap-and-trade program for NOX ozone
season emissions. Our technical analysis has shown that this SIP
revision is consistent with the requirements of 40 CFR Part 51,
including the specific CAIR NOX ozone season requirements at
40 CFR 51.123 as published on May 12, 2005, and further revised on
April 28 and December 13, 2006; and all applicable requirements of the
CAA.
As a consequence of this SIP approval, the Administrator of EPA
will also issue, without providing an opportunity for a public hearing
or an additional opportunity for written public comment, a final rule
to withdraw the CAIR FIP concerning NOX ozone season
emissions for Arkansas. This action will delete and reserve 40 CFR
52.184 in part 52.
VII. 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 and because this action will not have a significant, adverse
effect on the supply, distribution, or use of energy, 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. 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 approves a state rule
implementing a Federal standard, and does not alter the relationship or
the distribution of power and responsibilities established in the Act.
The EPA interprets Executive Order 13045, ``Protection of Children from
Environmental Health Risks and Safety Risks'' (62 FR 19885, April 23,
1997), as applying only to those regulatory actions that concern health
or safety risks such that the analysis required under section 5-501 of
the Executive Order has the potential to influence the regulation. This
rule is not subject to
[[Page 54561]]
Executive Order 13045 because it approves a state rule implementing a
Federal standard. Executive Order 12898 (59 FR 7629, February 16, 1994)
establishes federal executive policy on environmental justice. Because
this rule merely approves a state rule implementing a Federal standard,
EPA lacks the discretionary authority to modify today's regulatory
decision on the basis of environmental justice considerations.
In reviewing SIP submissions, EPA's role is to approve state
choices, provided that they meet the criteria of the 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 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. 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 November 26, 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).)
