Start Preamble

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to conditionally approve a State Implementation Plan (SIP) revision submitted by the State of Michigan on April 3, 2003. The submittal made by the Michigan Department of Environmental Quality (MDEQ) responds to the EPA's regulation entitled, “Finding of Significant Contribution and Rulemaking for Certain States in the Ozone Transport Assessment Group Region for Purposes of Reducing Regional Transport of Ozone,” otherwise known as the “NOX SIP Call.” The rules submitted by MDEQ establish and require nitrogen oxides (NOX) emissions reductions through an allowance trading program for large electric generating and industrial units, and reductions from cement kilns, beginning in 2004. The intended effect of the regulations submitted by MDEQ is to reduce emissions of NOX in order to help attain the national ambient air quality standard for ozone. We are proposing to conditionally approve Michigan's Oxides of Nitrogen Budget Trading Program because it generally meets the requirements of the Phase I NOX SIP Call that will significantly reduce ozone in Michigan and ozone transport in the eastern United States. We deemed the submittal as administratively and technically complete in a letter of completeness sent to MDEQ on April 24, 2003.

DATES:

We must receive written comments on or before March 29, 2004.

ADDRESSES:

You should send written comments to: J. Elmer Bortzer, Acting Chief, Air Programs Branch (AR-18J), U.S. Environmental Protection Agency, Region 5, 77 West Jackson Boulevard, Chicago, Illinois 60604.

II. Background

A. What Is EPA Proposing Today?

EPA is proposing to conditionally approve revisions to Michigan's SIP concerning the adoption of its NOX Rules, submitted on April 3, 2003. The rules meet the requirements of the Phase I NOX SIP Call with certain exceptions. MDEQ is in the process of adopting rules to correct these deficiencies. Once MDEQ has submitted the rule changes to address these deficiencies, we can take action to fully approve the SIP revision.

B. What Are the NOX SIP Call General Requirements?

On October 27, 1998, EPA published a final rule entitled, “Finding of Significant Contribution and Rulemaking for Certain States in the Start Printed Page 8907Ozone Transport Assessment Group Region for Purposes of Reducing Regional Transport of Ozone,” otherwise known as the “NOX SIP Call.” See 63 FR 57356. The NOX SIP Call requires 22 states and the District of Columbia to meet NOX emission budgets during the five month period from May 1 through September 30 in order to reduce the amount of ground level ozone that is transported across the eastern United States. As the result of court actions, the compliance date for the first year has been changed to May 31, 2004 and the NOX SIP Call has been divided into two phases.

EPA identified NOX emission reductions by source category that could be achieved by using highly cost-effective measures. The source categories included were large electric generating units (EGUs) and non-electric generating units (non-EGUs), internal combustion (IC) engines and cement kilns. EPA derived state-wide NOX emission budgets based on the implementation of these highly cost-effective controls for each affected jurisdiction to be met by the year 2007. Internal combustion engines are not addressed by Michigan in this submittal which responds to Phase I, but will be addressed in a response to EPA's Phase II requirements. The NOX SIP Call allowed states the flexibility to decide which source categories to regulate in order to meet the statewide budgets. In the NOX SIP Call notice, EPA suggested that a cap and trade program for EGUs (fossil-fuel fired electric generating boilers and turbines serving a generator greater than 25 MW) and non-EGUs (large fossil-fuel fired industrial boilers and turbines) would provide a highly cost-effective means for states to meet their NOX budgets. In fact, the state-specific budgets were set assuming an emission rate of 0.15 pounds NOX per million British thermal units (lb. NOX/mmBtu) at EGUs, multiplied by the projected heat input (mmBtu) from burning the quantity of fuel needed to meet the 2007 forecast for electricity demand (See 63 FR 57407). The NOX SIP Call State budgets also assume a 30 percent NOX reduction from cement kilns, and a 60 percent reduction from non-EGUs. The non-EGU control assumptions were applied at units whose maximum design heat input was greater than 250 mmBtu per hour, or in cases where heat input data were not available or appropriate, at units with actual emissions greater than one ton per day. Phase I budgets did not include reductions from IC engines. EPA's Phase II NOX SIP Call will address reductions from these sources.

To assist the states in their efforts to meet the SIP Call, the NOX SIP Call final rulemaking notice included a model NOX cap and trade regulation, called “NOX Budget Trading Program for State Implementation Plans,” (40 CFR part 96), that could be used by states to develop their regulations. The NOX SIP Call notice explained that if states developed an allowance trading regulation consistent with the EPA model rule, they could participate in a regional allowance trading program that would be administered by the EPA (See 63 FR 57458-57459).

There were several periods during which EPA received comments on various aspects of the NOX SIP Call emissions inventories. On March 2, 2000, EPA published additional technical amendments to the NOX SIP Call in the Federal Register (65 FR 11222). On March 3, 2000, the DC Circuit issued its decision on the NOX SIP Call ruling in favor of EPA on all the major issues. Michigan v. EPA, 213 F.3d 663 (D.C. Cir. 2000). The DC Circuit denied petitioners' requests for rehearing or rehearing en banc on July 22, 2000. However, the Circuit Court remanded four specific elements to EPA for further action: The definition of electric generating unit, the level of control for stationary internal combustion engines, the geographic extent of the NOX SIP Call for Georgia and Missouri, and the inclusion of Wisconsin. On March 5, 2001, the U.S. Supreme Court declined to hear an appeal by various utilities, industry groups and a number of upwind states from the DC Circuit's ruling on EPA's NOX SIP Call rule.

On April 11, 2000, in response to the Court's decision, EPA notified Michigan of the maximum amount of NOX emissions allowed for the State during the ozone season. This emission budget reflected adjustments to Michigan's NOX emission budget to reflect the Court's decision that Georgia and Missouri should not be included in full. Although the Court did not order EPA to modify Michigan's budget, the EPA believes these adjustments are consistent with the Court's decision.

On February 22, 2002 (67 FR 8396), EPA published a proposal that addresses the remanded portion of the NOX SIP Call Rule. Any additional emissions reductions required as a result of a final rulemaking on that proposal will be reflected in the second phase portion (Phase II) of the State's emission budget.

C. What Is EPA's NOX Budget and Allowance Trading Program?

EPA's model NOX budget and allowance trading rule, 40 CFR part 96, sets forth an NOX emissions trading program for large EGUs and non-EGUs. A state can voluntarily choose to adopt EPA's model rule in order to allow sources within its borders to participate in regional allowance trading. The October 27, 1998, Federal Register notice contains a full description of the EPA's model NOX budget trading program (See 63 FR 57514-57538 and 40 CFR part 96).

Air emissions trading, in general, uses market forces to reduce the overall cost of compliance for pollution sources, such as power plants, while achieving emission reductions and environmental benefits. One type of market-based program is an emissions budget and allowance trading program, commonly referred to as a “cap and trade” program.

In an emissions cap and trade program, the state or EPA sets a regulatory limit, or emissions budget or cap, for total mass emissions from a specific group of sources. The budget limits the total number of allowances for all sources covered by the program during a particular control period. When the budget is set at a level lower than the current emissions, the effect is to reduce the total amount of emissions during the control period. After setting the budget, the state or EPA then assigns, or allocates, allowances up to the level of the budget. Each allowance authorizes the emission of a quantity of pollutant, e.g., one ton of airborne NOX.

At the end of the control period, each affected source must demonstrate that its actual emissions during the control period were less than or equal to the number of available allowances it holds. Sources that reduce their emissions below their allocated allowance level may sell or bank their extra allowances. Sources that emit more than the amount of their allocated allowance level may buy allowances from the sources with extra reductions. In this way, the budget is met and in the most cost-effective manner.

D. EPA's Section 126 Rule in Michigan

In a rulemaking separate from the NOX SIP Call, EPA placed requirements directly on sources in Michigan, and many other states in the eastern half of the country, to reduce NOX emissions that adversely affect downwind areas in other states. This rule is known as EPA's Section 126 Rule (65 FR 2764). The Section 126 Rule is similar to the NOX SIP Call in that it is designed to address Start Printed Page 8908the problem of downwind transport and many of the sources that would be affected by states' NOX SIPs are also affected by the Section 126 Rule. The sources that are required to reduce emissions under the Section 126 Rule are EGUs (units serving a generator with nameplate capacity greater than 25 MW) and non-EGUs (units with maximum design heat input greater than 250 mmBtu/hr). These rules are different in that the NOX SIP Call is a requirement placed upon states to develop rules that will reduce NOX emissions but it is up to the state to determine what sources to control.

EPA issued the Section 126 rulemaking based on petitions filed by eight Northeastern States seeking to mitigate interstate transport of NOX. These petitions requested EPA to require NOX reductions from specific upwind NOX sources or source categories. EPA based its section 126 findings on the same technical work that was used in the NOX SIP Call.

E. What Guidance Did EPA Use To Evaluate Michigan's Submittal?

The final NOX SIP Call rule included a model NOX budget trading program regulation (See 40 CFR part 96). EPA used the model rule and 40 CFR 51.121-51.122 to evaluate Michigan's Oxides of Nitrogen Budget Trading Program for EGUs and non-EGUs. A cement kiln rule was included as part of a Federal Implementation Plan (FIP) that EPA proposed on October 28, 1998 (See 63 FR 56393). We used this proposed FIP cement kiln rule to evaluate Michigan's cement kiln rule.

F. What Is the Result of EPA's Evaluation of Michigan's Program?

EPA has evaluated Michigan's April 3, 2003, SIP submittal and finds the majority of it approvable. The Michigan Oxides of Nitrogen Budget Trading Program is basically consistent with EPA's guidance and almost meets all of the requirements of the Phase I NOX SIP Call. EPA finds the NOX control measures in the Michigan's Oxides of Nitrogen Budget Trading Program generally approvable. If it becomes fully approved, the April 3, 2003, submittal will strengthen Michigan's SIP for reducing ground level ozone by providing NOX reductions beginning in 2004. EPA finds that the submittal contained the information necessary to demonstrate that Michigan has the legal authority to implement and enforce the control measures, and to demonstrate their appropriate distribution of the compliance supplement pool. Furthermore, EPA finds that the submittal demonstrates that the compliance dates and schedules, and the monitoring, recordkeeping and emission reporting requirements will be met.

We identified certain deficiencies during our review but because MDEQ has been made aware of these problems and is currently in the process of addressing them, we are proposing to conditionally approve the submittal made by MDEQ on April 3, 2003. MDEQ requested this conditional approval of its April 2003 submittal in a letter dated January 9, 2004. In this letter, MDEQ has committed to submit fully adopted rules addressing the identified deficiencies by May 31, 2004. Upon receipt of these newly adopted rules eliminating all deficiencies, we can take action to fully approve Michigan's NOX SIP.

G. NOX Allowance Allocations

Because the vast majority of the SIP submitted by MDEQ has been found approvable by EPA and because MDEQ has committed to address the deficiencies identified by EPA, by no later than May 31, 2004, EPA will allocate NOX allowances to the affected sources in Michigan per the allocation methodology found in the Michigan SIP after finalization of this conditional approval.

H. NOX Budget Permits

State rules currently require the MDEQ to issue NOX Budget permits. Following EPA's final conditional approval of the Michigan NOX Rules into the Michigan SIP, the terms of any NOX Budget permit issued under the SIP-approved program are federally enforceable pursuant to the SIP.

I. What Deficiencies Must Be Addressed by MDEQ?

In the review of Michigan's NOX SIP, EPA identified six deficiencies that need to be corrected before these rules can be fully approved. These deficiencies have been communicated to MDEQ and now, MDEQ is in the process of changing its rules to address these problems.

Following is a list of the identified deficiencies:

1. Rule 802(5) states, “An oxides of nitrogen budget unit that is subject to a rule promulgated under section 126 of the Clean Air Act shall not be subject to this rule until the section 126 requirements no longer apply.” Under this language, those oxides of nitrogen budget units that are subject to the Section 126 Rule and that would be subject to controls under the Michigan SIP are not covered by the SIP. The Section 126 Rule remains in place and will remain effective until EPA approves the Michigan SIP. The EPA cannot approve the Michigan SIP, and move forward to remove the Section 126 requirements, unless the SIP has in place regulations to achieve the necessary emissions reductions to meet the Phase I budget. In evaluating the SIP, EPA cannot take into consideration the emissions reductions required by the Section 126 Rule. Because the Section 126 Rule would still be in place at the time EPA takes action on the Michigan SIP, oxides of nitrogen budget units that would otherwise be subject to controls under the Michigan SIP would not be covered at that time. Therefore, the SIP would not be providing sufficient emissions reductions to meet the Phase I budget and would not be approvable. This language must be removed from the State's rules. EPA will then take action to ensure that no unit is subject to both trading programs.

2. The applicability of these rules is based on named counties in the southern portion of Michigan. While this applicability is sufficient to meet the requirements found in the SIP Call, it is not enough to remove all of the Section 126 requirements from the State. This is because there is one source, Detroit Edison's Harbor Beach unit, that is affected by Section 126 requirements, but is not in one of the counties affected by Michigan's NOX SIP call rule. Michigan has indicated a desire to include the Harbor Beach unit in the trading program in order to satisfy the Section 126 requirements for this source. To address this situation and enable EPA to remove all of the Section 126 requirements from Michigan after the Michigan NOX SIP has been approved, MDEQ must extend the applicability of the Michigan NOX SIP to that one source.

3. Twenty-five ton exemption—States may develop alternative 25-ton NOX exemptions to the one included in the model rule provided they are based on permit restrictions that limit a unit's potential to emit during an ozone season to 25 tons or less and are not inconsistent with 40 CFR part 75 monitoring requirements. Michigan's regulation, Part 8. Emissions Limitations and Prohibitions—Oxides of Nitrogen, includes in Rule 802(2) the 25-ton exemption. The rule language is based on the model rule but provides additional options for qualifying for the exemption that involve emission monitoring or testing that is inconsistent with part 75.

In addition, when a unit receives a 25-ton exemption, the unit's potential emissions (reflected as an equivalent number of allowances) must be removed Start Printed Page 8909from the trading budget to avoid double counting. An exempt unit's emissions are included in the state's large EGU or large non-EGU emissions budget and therefore as allowances in the state's trading budget. EPA is concerned that Michigan's rule does not account for potential emissions from the exempt units. Neither the rule nor the SIP submittal specifies a procedure for removing from the trading budget the allowances reflecting the exempt unit's potential emissions. To address the deficiencies related to the 25-ton exemption provisions including the related budget adjustments, Michigan must modify its regulations to ensure an exempt source's emissions are less than 25 tons in each ozone season and provide a process for adjusting the trading budget accordingly. EPA provided MDEQ suggested language modifying the regulations.

4. New source set-aside—The new source set-aside provisions of § 811(1)(a) specify the set-aside pool allocation. The rule contains a typographical error regarding the number of allowances to be set-aside after 2006. A footnote in the Michigan SIP submittal highlights this error and indicates the correct number. This error should be corrected since the official regulations are the basis for all allocations. Also, Section 811(2) appears to address the issue of adjusting a new source's allowances to account for reduced utilization, but is incomplete and, for example, lacks the adjustment formula. This section also appears to specify how remaining set-aside allowances are determined, but that matter is also addressed in Section 811(3). Michigan must clarify these provisions. EPA provided MDEQ suggested language to clarify these provisions.

5. Language in § 802(1)(a) appears to allow the State to exempt an EGU for which applicability has not been determined. EPA cannot approve any exemption that is solely at the discretion of the State and does include EPA approval as well. The language relating to exemptions based solely on the State's discretion must be removed as a condition of final approval.

6. Language in § 804 relating to retired unit exemptions must be modified to include the requirement that a unit that qualifies for this exemption, is not required to have a permit, and subsequently resumes operation will lose the exemption at the time of resumption of operation. EPA provided MDEQ suggested language modifying this section of the regulations.

J. What Happens if MDEQ Fails To Address These Deficiencies?

In a letter dated, January 9, 2004, MDEQ committed to submit fully adopted rules addressing the deficiencies by May 31, 2004. If a submittal is not made by this date, this conditional approval will automatically revert to a disapproval of the Michigan NOX SIP.

III. Michigan's Control of NOX Emissions

A. When Did Michigan Submit the SIP Revision to EPA in Response to the NOX SIP Call?

On April 3, 2003, MDEQ submitted a final revision to its SIP to meet the requirements of the Phase I NOX SIP Call.

B. When Did Michigan Hold Public Hearings and What Were the Results?

Public hearings were held on December 3, 2001 and January 22, 2003. MDEQ holds public hearings on rules at the end of a 30-day public comment period. MDEQ either modified its rules to accommodate the comments received or explained why the rules were not changed in light of the comments.

C. What Is Included in Michigan's NOX SIP Call Revision?

Michigan allows, as in the model rule, EGUs and non-EGUs to participate in the multi-state cap and trade program. Cement kilns are not included in the trading program, but will be required to install low NOX burners, mid-kiln firing system or technology that achieves the same emission decreases (a 30% reduction). Michigan's SIP revision to meet the requirements of the NOX SIP Call consists of the revision of Michigan Rules 802 through 817. The regulations 802 through 816 affect EGUs and non-EGUs. Rule 817 applies requirements to cement manufacturing facilities.

Michigan's SIP revision to meet the requirements of the NOX SIP Call consists of the following Michigan Rules:

  • 802 Applicability under oxides of nitrogen budget trading program
  • 803 Definitions for oxides of nitrogen budget trading program
  • 804 Retired unit exemption from oxides of nitrogen budget trading program
  • 805 Standard requirements of oxides of nitrogen budget trading program
  • 806 Computation of time under oxides of nitrogen budget trading program
  • 807 Authorized account representative under oxides of nitrogen budget trading program
  • 808 Permit requirements under oxides of nitrogen budget trading program
  • 809 Compliance certification under oxides of nitrogen budget trading program
  • 810 Allowance allocations under oxides of nitrogen budget trading program
  • 811 New source set-aside under oxides of nitrogen budget trading program
  • 812 Allowance tracking system and transfers under oxides of nitrogen budget trading program
  • 813 Monitoring and reporting requirements under oxides of nitrogen budget trading
  • 814 Individual opt-ins under oxides of nitrogen budget trading program
  • 815 Allowance banking under oxides of nitrogen budget trading program
  • 816 Compliance supplement pool under oxides of nitrogen budget trading program
  • 817 Emission limitations and restrictions for Portland cement kilns

Michigan's Oxides of Nitrogen Budget Trading Program (Rules 802 through 816) establishes and requires a NOX allowance trading program for large EGUs and non-EGUs. These rules establish a NOX cap and allowance trading program for the ozone control seasons beginning May 31, 2004. Michigan Rule 817, not part of the trading program, applies to cement kilns and also requires control during the ozone season starting on May 31, 2004. Beginning in 2005, the ozone control period is May 1 through September 30.

The State of Michigan voluntarily chose to follow EPA's model NOX budget and allowance trading rule, 40 CFR part 96, that sets forth a NOX emissions trading program for EGUs and non-EGUs. Michigan's Oxides of Nitrogen Budget Trading Program is based upon EPA's model rule, therefore, Michigan sources are allowed to participate in the interstate NOX allowance trading program that EPA is administering for the participating states. The State of Michigan has adopted regulations that, revised consistent with the conditions noted above, are substantively identical to 40 CFR part 96. Therefore, with the conditions noted, pursuant to 40 CFR 51.121(p)(1), Michigan's SIP revision is being proposed for a conditional approval as satisfying the State's NOX emission reduction obligations. Under Rule 810, Michigan allocates NOX allowances to the EGU and non-EGU units that are affected by these requirements. The NOX trading program applies to EGUs (fossil fuel fired boilers Start Printed Page 8910and turbines serving a generator with a nameplate capacity greater than 25 MW or more that sell any amount of electricity) as well as non-EGUs (industrial boilers and turbines that have a maximum design heat input greater than 250 mmBtu per hour). Each NOX allowance permits a source to emit one ton of NOX during the seasonal control period. NOX allowances may be bought or sold. Unused NOX allowances may also be banked for future use, with certain limitations.

Source owners will monitor and report their NOX emissions by using methodologies that meet the requirements of 40 CFR part 75, subpart H, and report resulting data to EPA electronically. Each budget source complies with the program by demonstrating at the end of each control period that actual emissions do not exceed the amount of allowances held for that period. However, regardless of the number of allowances a source holds, it cannot emit at levels that would violate other federal or State limits, for example, reasonably available control technology (RACT), new source performance standards, or Title IV (the Federal Acid Rain program).

Michigan's Oxides of Nitrogen Budget Trading Program establishes requirements for cement manufacturing facilities, however, these sources are subject to NOX reduction requirements but do not participate in the NOX trading program. Michigan's submittal does not rely on any additional reductions beyond the anticipated federal measures in the mobile and area source categories.

Michigan's submittal demonstrates that the Phase I NOX emission budgets established by EPA will be met because MDEQ agrees with all of the assumptions, projections, etc. used by EPA to determine the 2007 budgets. Because Michigan has adopted all of the same controls assumed by EPA in developing the State's NOX budget, the actual emissions in 2007 should be the same as those EPA has projected to be the State's 2007 budget.

D. What Is the Compliance Supplement Pool?

To provide additional flexibility for complying with emission control requirements associated with the NOX SIP Call, the final NOX SIP Call rule provided each affected state with a “compliance supplement pool.” The compliance supplement pool is a quantity of NOX allowances that may be used to cover excess emissions from sources that are unable otherwise to meet control requirements during the 2004 and 2005 ozone season. Allowances from the compliance supplement pool will not be valid for compliance past the 2005 ozone season. The NOX SIP Call included these voluntary provisions in order to address commenters' concerns about the possible adverse effect that the control requirements might have on the reliability of the electricity supply or on other industries required to install controls as the result of a state's response to the NOX SIP Call.

A state may issue some or all of the compliance supplement pool via two mechanisms. First, a state may issue some or all of the pool to sources with credits from implementing NOX reductions beyond all applicable requirements after September 30, 1999, but before May 31, 2004 (i.e., early reductions). This allows sources that cannot install controls prior to May 31, 2004, to purchase other sources' early reduction credits in order to comply. Second, a state may issue some or all of the pool to sources that demonstrate a need for an extension of the May 31, 2004, compliance deadline due to undue risk to the electricity supply or other industrial sectors, and where early reductions are not available (See 40 CFR 51.121(e)(3)). Michigan has opted to issue the State's compliance supplement pool through the Early Reduction Credit program only.

E. How Does Michigan's NOX SIP Affect Sources Subject to EPA's Section 126 Rule in the SIP Call Area?

All of the existing sources in the SIP Call area that are subject to EPA's Section 126 Rule are also subject to Michigan's NOX rules. There is, however, one Section 126 affected source that falls outside of the SIP Call affected area. This source is Detroit Edison's Harbor Beach unit and it is located in Huron County. While Huron County falls outside of the area covered by the Michigan's NOX SIP rules, MDEQ is in the process of modifying the applicability of the NOX Rules to include this one source. Detroit Edison requested inclusion of the Harbor Beach unit in the State trading program because it would then be able to take advantage of the trading provisions that are not otherwise available. Since Michigan adopted the same applicability thresholds for EGU and non-EGU sources as those found in EPA's Section 126 Rule, all of the same sources will be covered once MDEQ has adopted rules to include the Harbor Beach unit. The Michigan trading budget was not increased as a result of adding the Harbor Beach unit.

IV. EPA Proposal

EPA is proposing to conditionally approve the Michigan's SIP revision consisting of its Oxides of Nitrogen Budget Trading Program and its rule that affects cement kilns, which was submitted on April 3, 2003. EPA finds that Michigan's submittal is conditionally approvable because it meets the requirements of the Phase I NOX SIP Call with some exceptions.

V. Statutory and Executive Order Reviews.

Executive Order 12866; Regulatory Planning and Review

Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is not a “significant regulatory action” and therefore is not subject to review by the Office of Management and Budget.

Executive Order 13211: Actions That Significantly Affect Energy Supply, Distribution, or Use

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).

Regulatory Flexibility Act

This action merely approves state regulations as meeting Federal requirements and imposes no additional requirements beyond those imposed by state regulations. Accordingly, the Administrator certifies that this rule will not have a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.).

Unfunded Mandates Reform Act

Because this rule approves pre-existing requirements under state law and does not impose any additional enforceable duty beyond that required by state law, it does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4).

Executive Order 13175 Consultation and Coordination With Indian Tribal Governments

This rule also does not have tribal implications because it will not have a substantial direct effect on one or more Indian tribes, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified by Executive Order 13175 (65 FR 67249, November 9, 2000).Start Printed Page 8911

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 is not economically significant.

National Technology Transfer Advancement Act

In reviewing plan 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 plan submission for failure to use VCS. It would thus be inconsistent with applicable law for EPA, when it reviews a plan submission, to use VCS in place of a plan 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. Section 804 exempts from section 801 the following types of rules: (1) Rules of particular applicability; (2) rules relating to agency management or personnel; and (3) rules of agency organization, procedure, or practice that do not substantially affect the rights or obligations of non-agency parties. 5 U.S.C. 804(3). EPA is not required to submit a rule report regarding this action under section 801 because this is a rule of particular applicability.

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 April 26, 2004. 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).)
