00-13199. Approval and Promulgation of Implementation Plans; Ohio Designation of Areas for Air Quality Planning Purposes; Ohio

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Final rule.

SUMMARY:

EPA is approving sulfur dioxide redesignation requests submitted by the State of Ohio on March 20, 2000, for Coshocton, Gallia, and Lorain Counties. This request was first submitted on October 26, 1995. Ohio subsequently provided supplemental material to EPA in a letter dated September 14, 1999. On March 20, 2000, Ohio submitted final requests to redesignate Coshocton, Gallia, and Lorain Counties to attainment of the National Ambient Air Quality Standards (NAAQS) for sulfur dioxide (SO₂).

EPA is also approving the maintenance plans for Coshocton, Gallia, and Lorain Counties. The plans are intended to ensure maintenance of the NAAQS for at least 10 years, and were submitted with the redesignation requests.

In conjunction with these actions, EPA is approving state-adopted emission limits for the following facilities: in Coshocton County: Columbus and Southern Ohio Electric—Conesville Plant; in Gallia County: Ohio Valley Electric Company—Kyger Creek Plant and Ohio Power—Gavin Plant; and in Lorain County: CEI—Avon Lake Plant, Ohio Edison—Edgewater Plant, U.S. Steel—Lorain Plant, and B.F. Goodrich Company—Lorain County Plant.

EPA is also approving other minor revisions in the state's rules for these three Counties.

On November 23, 1999, EPA received one comment on the proposal to redesignate Coshocton, Gallia, and Lorain Counties. American Electric Power (AEP) encouraged EPA to take final action to approve the redesignation.

DATES:

This rule is effective on July 5, 2000.

1. What Action Is EPA Taking Today?

In this action, EPA is approving SO₂ redesignation requests submitted by the State of Ohio for Coshocton, Gallia, and Lorain Counties. EPA is also approving the maintenance plans for these counties. In addition, EPA is approving state-adopted emission limits for sources in these three counties. EPA plans separate action on rules 3745-18-03, 3745-18-04, 3745-18-15, and 3745-18-71, that Ohio submitted along with rule revisions for these three counties.

2. Why Is EPA Taking This Action?

EPA is taking this action because the redesignation requests meet the five criteria all redesignation requests must meet. The limits in the submittal are approvable because they are at least as stringent as the current set of federally enforceable limits. Coshocton, Gallia, and Lorain Counties have been designated as nonattainment areas for sulfur dioxide but now meet the sulfur dioxide NAAQS. The three counties have plans for keeping their sulfur dioxide levels within the health and welfare-based standards for the next 10 years and beyond. The plans require the three counties to consider impacts of future activities on air quality and to manage those activities.

3. What Is the Background for This Action?

EPA promulgated the applicable Federal Implementation Plan (FIP) in 1976. The FIP required significant emission reductions at specific facilities throughout the state to attain and maintain the NAAQS for SO₂.

On October 5, 1978, Coshocton, Gallia, and Lorain Counties (among others) were designated as nonattainment areas for the primary sulfur dioxide standards. The state adopted its own regulations in 1979, generally imposing limits similar to those promulgated in the FIP. The state submitted these regulations for EPA approval in 1980, including regulations for Coshocton, Gallia, and Lorain Counties.

The state then withdrew its submittal for selected sources. These sources are:

1. Coshocton County

—Columbus and Southern Ohio Electric—Conesville plant

2. Gallia County

—Ohio Valley Electric Company—Kyger Creek plant

—Ohio Power—Gavin plant

3. Lorain County

—Cleveland Electric Illuminating (CEI)—Avon Lake plant

—Ohio Edison—Edgewater plant

—U.S. Steel—Lorain plant

—B.F. Goodrich Company

EPA approved this SIP regulation on January 27, 1981, for Coshocton, Gallia, and Lorain Counties (46 FR 8481) except for the source limits withdrawn by the state. The federally promulgated FIP regulations, therefore, have remained in effect for the above sources.

On October 26, 1995, Governor George Voinovich requested that EPA redesignate to attainment all remaining SO₂ nonattainment areas within the State of Ohio, including Coshocton, Gallia, and Lorain Counties.

On May 28, 1996, EPA Administrator Browner sent a letter to Governor Voinovich informing him that the redesignation request depended on EPA approval of state-adopted rules, such that the plan for assuring attainment would rely on approved State Rules rather than federally promulgated rules.

On September 14, 1999, Ohio provided supplemental supporting material for redesignation requests for three SO₂ nonattainment areas (Coshocton, Gallia, and Lorain Counties) to EPA.

On October 28, 1999 (64 FR 58018), EPA proposed approval of the redesignation requests for Coshocton, Gallia, and Lorain Counties, the maintenance plans, and the state-adopted emission limits.

The public comment period on this proposed approval ended on November 29, 1999; and only one comment, which was favorable, was received.

II. How Does the Proposed Submittal Compare to the Final Submittal?

For Gallia County emission limits, both the proposed and the final submittals are identical.

For the Coshocton County emission limits, paragraph (B)(4) of the final submittal, applying to two diesels at Columbus Southern Power Company, Conesville, was deleted based on evidence from the company's title V application that these units no longer operate. The final submittal indicates only 3 units (B006, B009, and B010) are in operation, instead of 5 units indicated in the proposed submittal.

For the Lorain County emission limits, paragraph (C) of the final submittal, applying to the General Motors Corporation, Fisher Body Division, was removed because this facility has been shutdown for 15 years. For the Avon Lake Plant, the state had two options in 3745-18-53, (B)(1) and (B)(2) or (B)(3) and (B)(4), for setting the facility's boilers' emission limits. Since the source only implements the strategy inherent in (B)(1) and (2), the limits in (B)(3) and (B)(4) had become irrelevant and were removed from the final state rule.

III. Public Comments and EPA Response

What Comments Did EPA Receive?

On November 23, 1999, EPA received one letter commenting on the proposed rulemaking. This letter, from AEP, encouraged EPA to take final action to approve the request as proposed. EPA received no adverse comments on this proposed rulemaking, and for the reasons provided in the proposal, concludes that the adopted emission limits, maintenance plans, and redesignation request for these counties should be approved.

IV. Background on Ohio Submittal

1. What Information Did Ohio Submit, and What Were Its Requests?

In June 1999, Ohio e-mailed copies of proposed rule revisions for Coshocton, Gallia, and Lorain Counties to EPA. On September 14, 1999, Ohio submitted additional material requested by EPA to support the state's requests to redesignate these Counties to attainment with respect to SO₂. On March 20, 2000, Ohio submitted final rule revisions with its final request for redesignation of these Counties to attainment for SO₂. In addition, the state requested approval for the SO₂ maintenance plans for Coshocton, Gallia, and Lorain Counties.

2. What Guidance Documents Did EPA Use in This Rulemaking To Evaluate Ohio's Requests?

Guidance for review of these requests includes a September 28, 1994, memorandum from the Director, Air Quality Management Division, Office of Air Quality Planning and Standards, EPA, to the Director, Air and Radiation Division, Region 5, entitled, “Response to Request for Guidance on Issues with Ohio Sulfur Dioxide Federal Implementation Plan.”

This memorandum sets forth three criteria to be met for the approval of state limits that are equivalent to existing FIP limits without new modeling. Under the first two criteria, there must be no known inadequacy in the original attainment demonstration. Under the third criterion, the state limits must reflect no relaxation of existing emission limits.

All three of these criteria are met by the state-promulgated SIP limits. Therefore, the revised limits, as adopted and submitted on March 20, 2000, are adequate to assure attainment without further modeling.

Another guidance document relevant to this rulemaking is an April 21, 1983, memorandum entitled “Section 107 Designation Policy Summary,” from the Director of EPA's Office of Air Quality Planning and Standards, which requires eight consecutive quarters of data showing SO₂ NAAQS attainment before an area can be redesignated. A county violates the NAAQS when its SO₂ level exceeds the NAAQS more than once in any year. Coshocton, Gallia, and Lorain Counties have eight consecutive quarters of data showing SO₂ NAAQS attainment. As discussed below, modeling-based evidence also indicates attainment of the SO₂ NAAQS.

Finally, a September 4, 1992 EPA policy memorandum on “Procedures for Processing Requests to Redesignate Areas to Attainment” was also relevant to this rulemaking. This memorandum explains that additional dispersion modeling is not required in support of an SO₂ redesignation request if an adequate modeled attainment demonstration was previously submitted and approved as part of the implemented SIP, and no indication of an existing air quality deficiency exists. These conditions are met here.

V. State Implementation Plan (SIP)

1. How Do State-Adopted Emission Limits Compare to the FIP Limits?

For facilities that are currently subject to FIP limits, the final state-adopted emission limits are equivalent to the FIP limits. A few emission points at these facilities have State limits but no FIP limits; approval of these State limits obviously increase the stringency of the SIP.

In Gallia County, for facilities currently subject to FIP limits, the State rules impose the same limits on the same set of emission points as the FIP. In Lorain County, the state's rules include limits for soaking pit process operations and seamless rotary furnace for USS/KOBE. In Coshocton County, the State's rules include limits for diesels and auxiliary boiler for Columbus Southern Power Company. Because these emission points are not currently subject to federally enforceable limits, these limits enhance the stringency of the State's plan.

The FIP limits at issue will become suspended upon approval of these submitted SIP limits, but would become applicable again if for any reason these SIP limits were rescinded in the future.

2. What Are the Sources and Emission Limits That Will Be Affected by EPA's Action?

The principal sources affected by this rulemaking are sources for which FIP limits are being superseded by limits in approved state rules. The table below lists these sources.

County names	State rules	Source names
Coshocton County	—OAC 3745-18-22 (B)	—Columbus and Southern Ohio Electric—Conesville.
Gallia County	—OAC 3745-18-33 (B)	—Ohio Valley Electric Company—Kyger Creek.
	—OAC 3745-18-33 (D)	—Ohio Power—Gavin.
Lorain County	—OAC 3745-18-53 (B)	—CEI—Avon Lake.
	—OAC 3745-18-53 (D)	—Ohio Edison—Edgewater Plant.
	—OAC 3745-18-53 (E)	—U.S. Steel
	—OAC 3745-18-53 (G)	—B.F. Goodrich.

This rulemaking also approves the removal of obsolete State limits that the State adopted in its final rulemaking.

VI. Maintenance Plan

1. How Does the Maintenance Plan Apply in Coshocton, Gallia, Lorain Counties?

Ohio's attainment plan for sulfur dioxide provides for attainment even with major sources emitting their maximum allowable emissions. Therefore, maintenance is provided by assuring that minor source impacts do not increase significantly. The principal minor sources are distant point sources and diesel vehicles.

2. What Are the Maintenance Plan Reduction Requirements?

Clean Air Act Title IV reductions and the required national conversion to low sulfur diesel fuel are the identified maintenance plan provisions for Coshocton, Gallia, and Lorain Counties.

VII. Redesignation Evaluation

1. What Five Criteria Did EPA Use To Review the Redesignation Requests?

Section 107(d)(3)(E) of the Clean Air Act (Act), as amended in 1990, establishes requirements to be met before an area may be redesignated from nonattainment to attainment. The criteria used to review redesignation requests are derived from the Act. An area can be redesignated to attainment if the following five conditions are met:

(A) The area has attained the applicable NAAQS.

(B) The area has a fully approved SIP under section 110(k) of the Act.

(C) The EPA has determined that the improvement in air quality in the area is due to permanent and enforceable emission reductions.

(D) The EPA has determined that the maintenance plan for the area has met all of the requirements of section 175A of the Act.

(E) The state has met all requirements applicable to the area under section 110 and part D of the Act.

2. Are These Five Criteria Satisfied for Coshocton, Gallia, and Lorain Counties?

A. Demonstrated Attainment of the NAAQS

Relevant Agency guidance is provided in both the April 21, 1983, and September 4, 1992 guidance documents cited above. The April 21, 1983 memorandum explains that eight consecutive quarters of data showing SO2 NAAQS attainment are required for redesignation. The September 4, 1992 guidance explains that the area must have no more than one exceedance per year.

Ohio's September 14, 1999 submittal provides ambient monitoring data showing that Coshocton, Gallia, and Lorain Counties have met the NAAQS for the years 1994-1999.

Dispersion modeling is commonly used to demonstrate attainment of the SO2 NAAQS. A modeling analysis was done in 1976 to show that, under all allowed operating scenarios, the emission limits in these three counties' SO2 SIPs would lead to attainment and maintenance of the SO2 standards. According to the September 4, 1992 memorandum, no further dispersion modeling is needed for the counties' redesignation. Ohio has provided evidence that sources in these counties are complying with these limits.

Based on this evidence, EPA concludes that emissions are sufficiently low to assure attainment throughout these areas currently designated nonattainment.

B. Fully Approved SIP

The SIP for the area at issue must be fully approved under section 110(k) of the Act and must satisfy all requirements that apply.

EPA's guidance for implementing section 110 of the Act is discussed in the General Preamble to Title I (44 FR 20372, April 14, 1979; and 57 FR 13498, April 16, 1992). The SO2 SIP for Coshocton, Gallia, and Lorain Counties met the requirements of section 110 of the Act, and EPA approved the SIP on January 27, 1981, except that EPA did not take action for a limited set of sources.

State limits for the remaining set of specific sources in Coshocton, Gallia, and Lorain Counties are being approved in this rulemaking. For convenience, EPA is rulemaking on rules for entire affected Counties, and is approving additional minor revisions in these Counties.

C. Permanent and Enforceable Reductions in Emissions

Coshocton, Gallia, and Lorain Counties attained the SO2 standards by implementing the SO2 SIP controls. The reductions in emissions primarily come from converting some fuel-burning sources to lower sulfur content fuels, and to shutting down various types of sources. The use of lower-sulfur “cleaner” fuels is ensured by the facilities' air emission permits and federally enforceable SIP regulations.

D. Fully Approved Maintenance Plan

EPA has concluded that the combination of limitations on maximum allowable emissions from major point sources and implementation of programs that will yield reductions in minor source emissions will assure maintenance of the standards. EPA is approving the maintenance plan in today's action.

E. Part D and Other Section 110 Requirements

With today's approval of limits submitted on March 20, 2000, along with the approval of limits and attainment demonstrations published on January 27, 1981 (46 FR 8481), Ohio has met the relevant requirements.

VIII. Final Rulemaking Action

In summary, EPA is approving state-adopted emission limits for 7 sources in Coshocton, Gallia, and Lorain Counties, as well as approving minor revisions for other sources in these Counties. EPA is also approving the SO₂ maintenance plan for Coshocton, Gallia, and Lorain Counties as adequately ensuring that attainment will be maintained. Finally, EPA is approving redesignation requests from the State of Ohio which were submitted on October 26, 1995, September 14, 1999 and on March 20, 2000.

IX. Administrative Requirements

A. Executive Order 12866

The Office of Management and Budget (OMB) has exempted this regulatory action from Executive Order 12866, entitled “Regulatory Planning and Review.”

B. Executive Order 13045

Protection of Children from Environmental Health Risks and Safety Risks (62 FR 19885, April 23, 1997), applies to any rule that: (1) is determined to be “economically significant” as defined under Executive Order 12866, and (2) concerns an environmental health or safety risk that EPA has reason to believe may have a disproportionate effect on children. If the regulatory action meets both criteria, the Agency must evaluate the environmental health or safety effects of the planned rule on children, and explain why the planned regulation is preferable to other potentially effective and reasonably feasible alternatives considered by the Agency.

This rule is not subject to Executive Order 13045 because it does not involve decisions intended to mitigate environmental health or safety risks.

C. Executive Order 13084

Under Executive Order 13084, EPA may not issue a regulation that is not required by statute, that significantly affects or uniquely affects the communities of Indian tribal governments, and that imposes substantial direct compliance costs on those communities, unless the Federal government provides the funds necessary to pay the direct compliance costs incurred by the tribal governments, or EPA consults with those governments. If EPA complies by consulting, Executive Order 13084 requires EPA to provide to the Office of Management and Budget, in a separately identified section of the preamble to the rule, a description of the extent of EPA's prior consultation with representatives of affected tribal governments, a summary of the nature of their concerns, and a statement supporting the need to issue the regulation. In addition, Executive Order 13084 requires EPA to develop an effective process permitting elected officials and other representatives of Indian tribal governments “to provide meaningful and timely input in the development of regulatory policies on matters that significantly or uniquely affect their communities.”

Today's rule does not significantly or uniquely affect the communities of Indian tribal governments. This action does not involve or impose any requirements that affect Indian Tribes. Accordingly, the requirements of section 3(b) of Executive Order 13084 do not apply to this rule.

D. Executive Order 13132

Federalism (64 FR 43255, August 10, 1999) revokes and replaces Executive Orders 12612 (Federalism) and 12875 (Enhancing the Intergovernmental Partnership). Executive Order 13132 requires EPA to develop an accountable process to ensure “meaningful and timely input by state and local officials in the development of regulatory policies that have federalism implications.” “Policies that have federalism implications” is defined in the Executive Order to include regulations that 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.” Under Executive Order 13132, EPA may not issue a regulation that has federalism implications, that imposes substantial direct compliance costs, and that is not required by statute, unless the Federal government provides the funds necessary to pay the direct compliance costs incurred by state and local governments, or EPA consults with state and local officials early in the process of developing the proposed regulation. EPA also may not issue a regulation that has federalism implications and that preempts state law unless the Agency consults with state and local officials early in the process of developing the proposed regulation.

This rule will 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, because it 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. Thus, the requirements of section 6 of the Executive Order do not apply to this rule.

E. Regulatory Flexibility

The Regulatory Flexibility Act (RFA) generally requires an agency to conduct a regulatory flexibility analysis of any rule subject to notice and comment rulemaking requirements unless the agency certifies that the rule will not have a significant economic impact on a substantial number of small entities. Small entities include small businesses, small not-for-profit enterprises, and small governmental jurisdictions.

This rule will not have a significant impact on a substantial number of small entities because SIP approvals under section 110 and subchapter I, part D of the Clean Air Act do not create any new requirements but simply approve requirements that the state is already imposing. Therefore, because the Federal SIP approval does not create any new requirements, I certify that this action will not have a significant economic impact on a substantial number of small entities. Moreover, due to the nature of the federal-state relationship under the Clean Air Act, preparation of flexibility analysis would constitute Federal inquiry into the economic reasonableness of state action. The Clean Air Act forbids EPA to base its actions concerning SIPs on such grounds. Union Electric Co. v. U.S. EPA, 427 U.S. 246, 255-66 (1976); 42 U.S.C. 7410(a)(2).

F. Unfunded Mandates

Under sections 202 of the Unfunded Mandates Reform Act of 1995 (“Unfunded Mandates Act”), signed into law on March 22, 1995, EPA must prepare a budgetary impact statement to accompany any proposed or final rule that includes a Federal mandate that may result in estimated costs to state, local, or tribal governments in the aggregate; or to the private sector, of $100 million or more. Under section 205, EPA must select the most cost-effective and least burdensome alternative that achieves the objectives of the rule and is consistent with statutory requirements. Section 203 requires EPA to establish a plan for informing and advising any small governments that may be significantly or uniquely impacted by the rule.

EPA has determined that the approval action promulgated does not include a Federal mandate that may result in estimated costs of $100 million or more to either state, local, or tribal governments in the aggregate, or to the private sector. This Federal action approves pre-existing requirements under state or local law, and imposes no new requirements. Accordingly, no additional costs to state, local, or tribal governments, or to the private sector, result from this action.

G. Submission to Congress and the Comptroller General

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).

H. National Technology Transfer and Advancement Act

Section 12 of the National Technology Transfer and Advancement Act (NTTAA) of 1995 requires Federal agencies to evaluate existing technical standards when developing a new regulation. To comply with NTTAA, EPA must consider and use “voluntary consensus standards” (VCS) if available and applicable when developing programs and policies unless doing so would be inconsistent with applicable law or otherwise impractical.

The EPA believes that VCS are inapplicable to this action. Today's action does not require the public to perform activities conducive to the use of VCS.

I. Petitions for Judicial Review

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 August 4, 2000. 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).)
