E7-19646. Approval of Implementation Plans of South Carolina: Clean Air Interstate Rule

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Direct final rule.

SUMMARY:

EPA is approving revisions to the South Carolina State Implementation Plan (SIP) submitted on August 14, 2007. These revisions incorporate provisions related to the implementation of EPA's Clean Air Interstate Rule (CAIR), promulgated on May 12, 2005 and subsequently revised on April 28, 2006 and December 13, 2006, and the CAIR Federal Implementation Plans (FIPs) concerning sulfur dioxide (SO₂), nitrogen oxides (NO_X) annual, and NO_X ozone season emissions for the State of South Carolina, promulgated on April 28, 2006 and subsequently revised December 13, 2006. EPA is not making any changes to the CAIR FIPs, but is amending the appropriate appendices in the CAIR FIP trading rules simply to note this approval.

On September 19, 2007, South Carolina requested that EPA only act on a portion of the August 14, 2007, submittal as an abbreviated SIP. Consequently, EPA is approving the abbreviated SIP revisions that address the methodology to be used to allocate annual and ozone season NO_X allowances under the CAIR FIPs as well as opt-in provisions for the SO₂, NO_X annual, and NO_X ozone season trading programs. South Carolina also requested that EPA approve compliance supplement pool (CSP) provisions for the NO_X annual trading program.

DATES:

This direct final rule is effective December 10, 2007 without further notice, unless EPA receives adverse comment by November 8, 2007. If EPA receives such comments, it will publish a timely withdrawal of the direct final rule in the Federal Register and inform the public that the rule will not take effect.

I. What Action Is EPA Taking?

CAIR SIP Approval

EPA is approving revisions to the South Carolina SIP, submitted on August 14, 2007, and revised on September 19, 2007, that would modify the application of certain provisions of the CAIR FIPs concerning SO₂, NO_X annual, and NO_X ozone season emissions. (As discussed below, this less comprehensive CAIR SIP is termed an abbreviated SIP.) South Carolina is subject to the CAIR FIPs that implement the CAIR requirements by requiring certain EGUs to participate in the EPA-administered Federal CAIR SO₂, NO_X annual, and NO_X ozone season cap-and-trade programs. The SIP revision provides a methodology for allocating NO_X allowances for the NO_X annual and NO_X ozone season trading programs. The CAIR FIPs provide that this methodology, if approved by EPA, will be used to allocate NO_X allowances to sources in South Carolina, instead of the Federal allocation methodology otherwise provided in the FIP. The SIP revision also provides a methodology for allocating the compliance supplement pool in the CAIR NO_X annual trading program, and allows for individual units not otherwise subject to the CAIR trading programs to opt into such trading programs. Specifically, EPA is approving South Carolina's SIP submission that includes the allocation methodologies for the CAIR NO_X annual and NO_X ozone season trading programs and CAIR FIP opt-in provisions. The SIP revision also addresses South Carolina's CSP provisions in the CAIR NO_X annual trading program. Consistent with the flexibility provided in the FIPs, these provisions will also be used to replace or supplement, as appropriate, the corresponding provisions in the CAIR FIPs for South Carolina. EPA is not making any changes to the CAIR FIPs, but is amending the appropriate appendices in the CAIR FIP trading rules simply to note this approval.

EPA is publishing this rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. However, in the proposed rules section of this Federal Register publication, EPA is publishing a separate document that will serve as the proposal to approve the SIP revision should adverse comments be filed.

II. What Is the Regulatory History of the CAIR and the CAIR FIPs?

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 particulates (PM_2.5) 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 PM_2.5 formation, and/or NO_X, which is a precursor to both ozone and PM_2.5 formation. For jurisdictions that contribute significantly to downwind PM_2.5 nonattainment, CAIR sets annual State-wide emission reduction requirements (i.e., budgets) for SO₂ and annual State-wide emission reduction requirements for NO_X. Similarly, for jurisdictions that contribute significantly to 8-hour ozone nonattainment, CAIR sets State-wide emission reduction requirements for NO_X for the ozone season (May 1st to September 30th). Under CAIR, States may implement these emission budgets by participating in the EPA-administered cap-and-trade programs or by adopting any other control measures.

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 PM_2.5 NAAQS. EPA made national findings, effective 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 PM_2.5 NAAQS. These findings started a 2-year clock for EPA to promulgate a 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 FIPs for all States covered by CAIR in order to ensure the emissions reductions required by CAIR are achieved on schedule. Each CAIR State is subject to the FIPs 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, NO_X annual, and NO_X ozone-season model trading programs, as appropriate. The CAIR FIP SO₂, NO_X annual, and NO_X 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, NO_X annual, and NO_X ozone season) in all States covered by a 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 the corresponding CAIR FIP provisions (e.g., the methodology for allocating NO_X allowances to sources in the state), while the CAIR FIP remains in place for all other provisions.

On April 28, 2006, EPA published two more CAIR-related final rules that added the States of Delaware and New Jersey to the list of States subject to CAIR for PM_2.5 and announced EPA's final decisions on reconsideration of five issues without making any substantive changes to the CAIR requirements.

III. What Are the General Requirements of CAIR and the CAIR FIPs?

CAIR establishes State-wide emission budgets for SO₂ and NO_X and is to be implemented in two phases. The first phase of NO_X reductions starts in 2009 and continues through 2014, while the first phase of SO₂ reductions starts in 2010 and continues through 2014. The second phase of reductions for both NO_X 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 NO_X 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.

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 NO_X SIP Call trading programs in their CAIR NO_X ozone season trading programs.

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 CAIR FIPs. Alternatively, States may submit abbreviated SIP revisions. These SIP revisions will not replace the CAIR FIPs; however, the CAIR FIPs provide that, when approved, the provisions in these abbreviated SIP revisions will be used instead of or in conjunction with, as appropriate, the corresponding provisions of the CAIR FIPs (e.g., the NO_X allowance allocation methodology).

A State submitting an abbreviated SIP revision, may submit limited SIP revisions to tailor the CAIR FIP cap-and-trade programs to the State submitting the revision. Specifically, an abbreviated SIP revision may establish certain applicability and allowance allocation provisions that, the CAIR FIPs provide, will be used instead of or in conjunction with the corresponding provisions in the CAIR FIP rules in that State. Specifically, the abbreviated SIP revisions may:

1. Include NO_X SIP Call trading sources that are not EGUs under CAIR in the CAIR FIP NO_X ozone season trading program;

2. Provide for allocation of NO_X annual or ozone season allowances by the State, rather than the Administrator of the EPA or the Administrator's duly authorized representative (Administrator), and using a methodology chosen by the State;

3. Provide for allocation of NO_X annual allowances from the CSP by the State, rather than by the Administrator, and 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 FIP cap-and-trade programs under the opt-in provisions in the CAIR FIP rules.

With approval of an abbreviated SIP revision, the CAIR FIPs remain in place, as tailored to sources in the State by the approved SIP revisions.

Abbreviated SIP revisions can be submitted in lieu of, or as part of, CAIR full SIP revisions. States may want to designate part of their full SIP as an abbreviated SIP for EPA to act on first when the timing of the State's submission might not provide EPA with sufficient time to approve the full SIP prior to the deadline for recording NO_X allocations. This will help ensure that the elements of the trading programs where flexibility is allowed are implemented according to the State's decisions. Submission of an abbreviated SIP revision does not preclude future submission of a CAIR full SIP revision. In this case, the September 19, 2007, submittal from South Carolina has been submitted as an abbreviated SIP revision.

V. Analysis of South Carolina's CAIR SIP Submittal

A. State Budgets for Allowance Allocations

The CAIR NO_X annual and ozone season budgets 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 pounds per million British thermal units (lb/mmBtu), for phase 1, and 0.125 lb/mmBtu, for phase 2, to obtain regional NO_X budgets for 2009-2014 and for 2015 and thereafter, respectively. EPA derived the State NO_X annual and ozone season budgets from the regional budgets using State heat input data adjusted by fuel factors.

The CAIR State SO₂ budgets were derived by discounting the tonnage of emissions authorized by annual allowance allocations under the Acid Rain Program under title IV of the CAA. Under CAIR, each allowance allocated under the Acid Rain Program for the years in phase 1 of CAIR (2010 through 2014) authorizes 0.50 ton of SO₂ emissions in the CAIR trading program, and each Acid Rain Program allowance allocated for the years in phase 2 of CAIR (2015 and thereafter) authorizes 0.35 ton of SO₂ emissions in the CAIR trading program.

The CAIR FIPs established the budgets for South Carolina as 32,662 tons for NO_X annual emissions for 2009-2014 and 27,219 tons for NO_X annual emissions for 2015 and thereafter, 15,249 tons for NO_X ozone season emissions for 2009-2014 and 12,707 tons for NO_X ozone season emissions for 2015 and thereafter, and 57,271 tons for SO₂ emissions for 2009-2014 and 40,089 tons for SO₂ emissions for 2015 and thereafter. South Carolina's SIP revision, being approved in this action, does not affect these budgets, which are total amounts of allowances available for allocation for each year under the EPA-administered cap-and-trade programs under the CAIR FIPs. In short, the abbreviated SIP revision only affects allocations of allowances under the established budgets.

B. CAIR Cap-and-Trade Programs

The CAIR NO_X annual and ozone-season FIPs both largely mirror the structure of the NO_X SIP Call model trading rule in 40 CFR part 96, subparts A through I. While the provisions of the NO_X annual and ozone-season FIPs are similar, there are some differences. For example, the NO_X annual FIP (but not the NO_X ozone season FIP) provides for a CSP, which is discussed below and under which allowances may be awarded for early reductions of NO_X annual emissions. As a further example, the NO_X ozone season FIP reflects the fact that the CAIR NO_X ozone season trading program replaces the NO_X SIP Call trading program after the 2008 ozone season and is coordinated with the NO_X SIP Call program. The NO_X ozone season FIP provides incentives for early emissions reductions by allowing banked, pre-2009 NO_X SIP Call allowances to be used for compliance in the CAIR NO_X ozone-season trading program. In addition, States have the option of continuing to meet their NO_X SIP Call requirement by participating in the CAIR NO_X ozone season trading program and including all their NO_X SIP Call trading sources in that program.

The provisions of the CAIR SO₂ FIP are also similar to the provisions of the NO_X annual and ozone season FIPs. However, the SO₂ FIP is coordinated with the ongoing Acid Rain SO₂ cap-and-trade program under CAA title IV. The SO₂ FIP uses the title IV allowances for compliance, with each allowance allocated for 2010-2014 authorizing only 0.50 ton of emissions and each allowance allocated for 2015 and thereafter authorizing only 0.35 ton of emissions. Banked title IV allowances allocated for years before 2010 can be used at any time in the CAIR SO₂ cap-and-trade program, with each such allowance authorizing 1 ton of emissions. Title IV allowances are to be freely transferable among sources covered by the Acid Rain Program and sources covered by the CAIR SO₂ cap-and-trade program.

EPA used the CAIR model trading rules as the basis for the trading programs in the CAIR FIPs. The CAIR FIP trading 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, NO_X annual, and NO_X ozone season trading rules and the respective CAIR FIP trading rules are designed to work together as integrated SO₂, NO_X annual, and NO_X ozone season trading programs.

South Carolina is subject to the CAIR FIPs for ozone and PM_2.5 and the CAIR FIP trading programs for SO₂, NO_X annual, and NO_X ozone season which apply to sources in South Carolina. Consistent with the flexibility they give to States, the CAIR FIPs provide that States may submit abbreviated SIP revisions that will replace or supplement, as appropriate, certain provisions of the CAIR FIP trading programs. The August 14, 2007, submission of South Carolina is such an abbreviated SIP revision.

C. Applicability Provisions for Non-Electric Generating Units (EGU) NO_X SIP Call Sources

In general, the CAIR FIP 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 megawatt electrical (MWe) producing electricity for sale.

States have the option of bringing in, for the CAIR NO_X ozone season program only, those units in the State's NO_X SIP Call trading program that are not EGUs as defined under CAIR. EPA advises States exercising this option to use provisions for applicability that are substantively identical to the provisions in 40 CFR 96.304 and add the applicability provisions in the State's NO_X SIP Call trading rule for non-EGUs to the applicability provisions in 40 CFR 96.304 in order to include in the CAIR NO_X ozone season trading program all units required to be in the State's NO_X SIP Call trading program that are not already included under 40 CFR 96.304. Under this option, the CAIR NO_X ozone season program must cover all large industrial boilers and combustion turbines, as well as any small EGUs (i.e., units serving a generator with a nameplate capacity of 25 MWe or less), that the State currently requires to be in the NO_X SIP Call trading program.

Consistent with the flexibility given to States in the CAIR FIPs, in the abbreviated SIP revision being approved in today's action, South Carolina has not chosen to expand the applicability provisions of the CAIR NO_X ozone season trading program to include all non-EGUs in the State's NO_X SIP Call trading program. EPA notes that South Carolina has indicated that it intends to submit subsequently a full SIP revision that expands the applicability provisions of the CAIR NO_X ozone season trading program in this manner.

D. NO_X Allowance Allocations

Under the NO_X allowance allocation methodology in the CAIR model trading rules and in the CAIR FIPs, NO_X annual and 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 FIPs 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 FIPs provide States the flexibility to establish a different NO_X allowance allocation methodology that will be used to allocate allowances to sources in the States 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 NO_X 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 the CAIR FIPs, South Carolina has chosen to replace the provisions of the CAIR NO_X annual FIP concerning the allocation of NO_X annual allowances with its own methodology. South Carolina has chosen to distribute NO_X annual allowances by adopting, with certain revisions, the CAIR NO_X annual trading program model rule at 40 CFR 96.141 and 96.142.

Consistent with the flexibility given to States in the CAIR FIPs, South Carolina has chosen to replace the provisions of the CAIR NO_X ozone season FIP concerning allowance allocations with their own methodology. South Carolina has chosen to distribute NO_X ozone season allowances by adopting, with certain revisions, the CAIR NO_X ozone season trading program model rule at 40 CFR 96.341 and 96.342.

E. Allocation of NO_X Allowances From the Compliance Supplement Pool

The CSP provides an incentive for early reductions in NO_X annual emissions. The CSP consists of 200,000 CAIR NO_X annual allowances of vintage 2009 for the entire CAIR region, and a State's share of the CSP is based upon the State's share of the projected emission reductions under CAIR. States may distribute CSP allowances, one allowance for each ton of early reduction, to sources that make NO_X reductions during 2007 or 2008 beyond what is required by any applicable State or Federal emission limitation. States also may distribute CSP allowances based upon a demonstration of need for an extension of the 2009 deadline for implementing emission controls.

The CAIR NO_X annual FIP establishes specific methodologies for allocations of CSP allowances. States may choose an allowed, alternative CSP allocation methodology to be used to allocate CSP allowances to sources in those States.

Consistent with the flexibility given to States in the FIP, South Carolina has chosen to modify the provisions of the CAIR NO_X annual FIP concerning the allocation of allowances from the CSP. South Carolina has chosen to distribute CSP allowances by adopting, with certain revisions, the CAIR NO_X annual CSP provisions in the model rule at 40 CFR 96.143.

F. Individual Opt-In Units

The opt-in provisions allow for 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 recording 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 the 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. The rules for each of the CAIR FIP trading programs include opt-in provisions that are essentially the same as those in the respective CAIR SIP model rules, except that the CAIR FIP opt-in provisions become effective in a State only if the State's abbreviated SIP revision adopts the opt-in provisions. The State may adopt the opt-in provisions entirely or may adopt them but exclude one of the allowance allocation methodologies. The State also has the option of not adopting any opt-in provisions in the abbreviated SIP revision and thereby providing for the CAIR FIPs trading program to be implemented in the State without the ability for units to opt into the program.

Consistent with the flexibility given to States in the FIPs, South Carolina has chosen to allow non-EGUs meeting certain requirements to participate in the CAIR NO_X annual trading program. The South Carolina rule allows for both of the opt-in allocation methods as specified in 40 CFR part 97 Subpart II of the CAIR NO_X annual trading program.

Consistent with the flexibility given to States in the FIPs, South Carolina has chosen to permit non-EGUs meeting certain requirements to participate in the CAIR NO_X ozone season trading program. The South Carolina rule allows for both of the opt-in allocation methods as specified in 40 CFR part 97 Subpart IIII of the CAIR NO_X ozone season trading program.

Consistent with the flexibility given to States in the FIPs, South Carolina has chosen to allow certain non-EGUs to opt into the CAIR SO₂ trading program. The South Carolina rule allows for both of the opt-in allocation methods as specified in 40 CFR part 97 Subpart III of the CAIR SO₂ trading program.

VI. Final Action

EPA is approving South Carolina's abbreviated CAIR SIP revisions submitted on September 19, 2007. South Carolina is covered by the CAIR FIPs, which requires participation in the EPA-administered CAIR FIP cap-and-trade programs for SO₂, NO_X annual, and NO_X ozone season emissions. Under these abbreviated SIP revisions and consistent with the flexibility given to States in the FIPs, South Carolina adopts provisions for allocating allowances under the CAIR FIP NO_X annual and ozone season trading programs. EPA is approving South Carolina's CAIR NO_X annual and ozone season allocation provisions for units subject to the CAIR trading programs under the current CAIR FIP NO_X annual and ozone season applicability provisions. In addition, South Carolina adopts in the abbreviated SIP revision provisions that establish a methodology for allocating allowances in the CSP and allow for individual non-EGUs to opt into the CAIR FIP SO₂, NO_X annual, and NO_X ozone season cap-and-trade programs. EPA is approving South Carolina's allowing for opt-in units and therefore the application of the opt-in provisions in these CAIR FIP trading programs to units in South Carolina.

As provided for in the CAIR FIPs, these provisions in the abbreviated SIP revision will replace or supplement the corresponding provisions of the CAIR FIPs in South Carolina. The abbreviated SIP revision meets the applicable requirements in 40 CFR 51.123(p) and (ee), with regard to NO_X annual and NO_X ozone season emissions, and 40 CFR 51.124(r), with regard to SO₂ emissions. EPA is not making any changes to the CAIR FIPs, but is amending the appropriate appendices in the CAIR FIP trading rules simply to note this approval.

EPA is approving the aforementioned changes to the SIP. EPA is publishing this rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. However, in the proposed rules section of this Federal Register publication, EPA is publishing a separate document that will serve as the proposal to approve the SIP revision should adverse comments be filed. This rule will be effective December 10, 2007 without further notice unless the Agency receives adverse comments by November 8, 2007.

If the EPA receives such comments, then EPA will publish a document withdrawing the final rule and informing the public that the rule will not take effect. All public comments received will then be addressed in a subsequent final rule based on the proposed rule. EPA will not institute a second comment period. Parties interested in commenting should do so at this time. If no such comments are received, the public is advised that this rule will be effective on December 10, 2007 and no further action will be taken on the proposed rule.

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, 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 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.

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. 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 December 10, 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)).
