AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to grant conditional approval of a State Implementation Plan (SIP) revision submitted by the State of West Virginia pertaining to nitrogen oxides (NOX) emission reductions required under the NOX SIP Call. The SIP revision, required under Phase II of the NOX SIP Call (Phase II), consists of West Virginia's rule to meet its remaining NOX emission reduction obligations. In order to meet the April 2005 SIP revision submission due date specified under Phase II, the West Virginia Department of the Environment (WVDEP) adopted this rule using West Virginia's emergency rule procedures. In West Virginia, such emergency rules have a sunset date. In order for West Virginia to have a fully approvable SIP revision to satisfy Phase II, the WVDEP must adopt a permanent rule with an effective date prior to the sunset date of the emergency rule, and must submit the permanent rule as a SIP revision to EPA by July 1, 2006. The WVDEP is currently in the process of adopting its permanent version of the rule to satisfy the Phase II requirements. The WVDEP has submitted a written commitment to EPA stating it will adopt the permanent rule with an effective date prior to the sunset date of the emergency rule, and will submit the permanent rule as a SIP revision to EPA by July 1, 2006. EPA is proposing to grant conditional approval of this SIP revision based upon West Virginia's commitments. This action is being taken under the Clean Air Act (CAA).

SUPPLEMENTARY INFORMATION:

West Virginia's Phase I NOX SIP Call trading program was approved as part of the West Virginia SIP on May 10, 2002 (67 FR 31733). On April 21, 2004 (69 FR 21604), EPA promulgated Phase II of the NOX SIP Call which, among other changes, adjusted state budgets downward to reflect emission reductions based upon the application of cost effective controls on stationary internal combustion (IC) engines that emitted more than one ton of NOX per average ozone season day in 1995. On March 30, 2005, the State submitted a revision to its SIP to satisfy the additional emission reductions required under Phase II. The March 30, 2005 submittal is comprised of an emergency rule that sunsets after 15 months, on June 2, 2006. However, in its March 30, 2005 SIP submittal, the WVDEP indicated that it is in the process of adopting an identical permanent rule. On August 15, 2005, the WVDEP submitted a letter committing to adopt a permanent rule having an effective date prior to the sunset date of its emergency rule, and committing to submit the permanent rule as a SIP revision to EPA by July 1, 2006.

I. Background

EPA issued the NOX SIP Call (63 FR 57356, October 27, 1998) to require 22 Eastern states and the District of Columbia to reduce specified amounts of one of the main precursors of ground-level ozone, NOX, in order to reduce interstate ozone transport. EPA found that the sources in these states emit NOX in amounts that contribute significantly to nonattainment of the 1-hour ozone national ambient air quality standard (NAAQS) in downwind states. In the NOX SIP Call, the amount of reductions required by states were calculated based on application of available, highly cost-effective controls on source categories of NOX.Start Printed Page 61105

The NOX SIP Call, including the Technical Amendments which addressed the 2007 electric generating units (EGU) budgets (64 FR 26298, May 14, 1999 and 65 FR 11222, March 2, 2000), was challenged by a number of state, industry, and labor groups. A summary of the NOX SIP Call requirements, including details of the court decisions that were made in response to challenges to the rule and impacts of the court decisions on certain aspects of the rule may be found in EPA's rulemaking dated April 21, 2004 (69 FR 21604) entitled, “Interstate Ozone Transport: Response to Court Decisions on the NOX SIP Call, NOX SIP Call Technical Amendments, and Section 126 Rules.” The relevant portions of the April 21, 2004 rulemaking that affect West Virginia's obligations under the NOX SIP Call, and that pertain to the State's requirements for Phase II, are discussed in this document to provide background on the March 30, 2005 SIP revision submitted by the WVDEP.

On March 3, 2000, the United States Court of Appeals for the District of Columbia Circuit (DC Circuit) issued its decision on the NOX SIP Call, Michigan v. EPA, 213 F.3rd 663 (DC Dir. 2000). While the DC Circuit ruled largely in favor of EPA in support of its requirements under the 1-hour ozone NAAQS, it also ruled, in part, against EPA on certain issues. The rulings against EPA included two areas of the NOX SIP Call that were remanded and vacated and two areas in which EPA was found to have failed to provide adequate notice of changes in the rule.

In the latter case, the rulings included a failure to provide adequate notice of the change in the definition of EGU as applied to cogeneration (cogen) units that supply electricity to a utility power distribution system for sale in certain specified amounts, and a failure to provide adequate notice of the change in the control level EPA assumed for large stationary internal combustion (IC) engines. The portions of the NOX SIP Call that were upheld by the Court were termed “Phase I” of the rule. With the exception of the remand of the EGU growth factors used in the NOX SIP Call and the requirements for the 8-hour ozone NAAQS (which EPA stayed due to uncertainty created by the court rulings), those portions of the NOX SIP Call that had been remanded back to EPA were finalized in the April 21, 2004 rulemaking (69 FR 21604) and termed “Phase II” of the rule.

The April 21, 2004 rule finalized specific changes to the definition of EGUs as applied to cogen units, finalized the control levels assumed for large stationary IC engines in the NOX SIP Call, adjusted states' total budgets (as necessary) to reflect these changes, established a SIP submittal date of April 1, 2005 for states to address the Phase II portion of the budget, and set a compliance date of May 1, 2007 for all affected sources to meet Phase II. As a result of these changes, states that were not already meeting their total NOX SIP Call emission reduction obligations were required to submit a SIP revision by April 1, 2005 to reduce ozone season NOX emissions by an incremental amount equivalent to the reductions achieved by controlling IC engines to prescribed levels. The IC engines that comprise the subject states' Phase II inventory were compiled by EPA and termed the EPA's NOX SIP Call Engine Inventory (65 FR 1222, March 2, 2000). As finalized in the April 21, 2005 rulemaking, the amount of the incremental reductions required was based upon the level of reductions that would occur if large natural gas-fired stationary IC engines were controlled to a level of 82 percent, and large diesel and dual fuel stationary IC engines were controlled to a level of 90 percent.

The change to the definition of cogen units did not have an impact on the Phase I budget previously established for West Virginia. Therefore, in order to meet its NOX SIP Call obligations, the State was required only to achieve the incremental reductions that EPA calculated based on controlling stationary IC engines to prescribed levels. As in Phase I of the NOX SIP Call, states have flexibility in how they achieve the incremental reductions required under Phase II. West Virginia chose to require the reductions from large IC engines, allowing creditable reductions on a facility-wide basis, and developed a rule largely based on EPA's model language for Phase II requirements.

II. Summary of SIP Revision

On March 30, 2005, the State of West Virginia submitted a revision to its SIP pertaining to emission reductions to satisfy Phase II of the NOX SIP Call. The SIP revision consists of Emergency Rule 45CSR1 entitled, “Control and Reduction of Nitrogen Oxides from Non-electric Generating Units as a Means to Mitigate Transport of Ozone Precursors,” which amends West Virginia's existing rule 45CSR1 to include the Phase II requirements. The revision applies to owners or operators of large stationary IC engines in the State of West Virginia. A large IC engine is defined as an engine that emitted more than one ton of NOX per average ozone season day in 1995.

In its March 30, 2005 submittal, West Virginia included an incremental budget demonstration that listed seven large natural gas-fired IC engines that are subject to Phase II, consistent with EPA's NOX SIP Call Engine Inventory. Application of 82 percent control to these units for the projected 2007 base case resulted in an incremental reduction of 903 tons of NOX emissions. EPA has determined that an additional reduction of 903 tons of NOX satisfies all of West Virginia's remaining requirements under the NOX SIP Call, and that this amount appropriately adjusts the incremental reduction specified in the April 21, 2004 rulemaking.

Emergency Rule 45 CSR1 contains revisions to West Virginia's existing NOX Budget Trading Program that enables the State to implement the additional requirements under Phase II of the NOX SIP Call. Sources in West Virginia that are subject to the new requirements must submit a compliance plan to WVDEP by May 1, 2006, and reduce ozone season NOX emissions in the state by an additional 903 tons beginning May 1, 2007. The revised rule also includes the pertinent definitions associated with stationary IC engines, and also adds a new Section 90 which sets forth general provisions, applicability provisions, the required ozone season NOX emission reductions, requirements for compliance plans, and the monitoring, recordkeeping, and reporting requirements necessary to determine compliance with the required emission reductions from stationary IC engines. The rule also incorporates the monitoring and reporting revisions set forth in 40 CFR Part 97 to align it with modifications that had been made to 45 CFR Part 75.

III. Proposed Action

EPA is proposing to grant conditional approval of West Virginia's March 30, 2005 SIP revision which consists of West Virginia's Emergency Rule 45CSR1 to meet Phase II of the NOX SIP Call. For West Virginia's Rule 45CSR1 to become fully approvable, the State of West Virginia must, in accordance with its August 15, 2005 commitment, fulfill the following conditions:

(1) Adopt a permanent Rule 45CSR1 with an effective date prior to the sunset date of the emergency rule, and

(2) Submit permanent rule 45CSR1 as a SIP revision to EPA by July 1, 2006. Once West Virginia fulfills these conditions, EPA will conduct rulemaking to convert its conditional approval to a full approval. If the conditions are not fulfilled within the specified time frame, any final Start Printed Page 61106conditional approval granted by EPA will convert to a disapproval. EPA is soliciting public comments on proposed action and issues discussed in this document. These comments will be considered before taking final action.

IV. Statutory and Executive Order Reviews

Under Executive Order 12866 (58 FR 51735, October 4, 1993), this proposed 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 Fed. Reg. 28355 (May 22, 2001)). This action merely proposes to approve state law as meeting Federal requirements and imposes no additional requirements beyond those imposed by state law. Accordingly, the Administrator certifies that this proposed 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 proposes to approve 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 proposed rule also does 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), nor will it 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), because it merely proposes to approve a state rule implementing a Federal requirement, and does not alter the relationship or the distribution of power and responsibilities established in the Clean Air Act. This proposed rule also is not subject to Executive Order 13045 (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 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 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 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. As required by section 3 of Executive Order 12988 (61 FR 4729, February 7, 1996), in issuing this proposed rule, EPA has taken the necessary steps to eliminate drafting errors and ambiguity, minimize potential litigation, and provide a clear legal standard for affected conduct. EPA has complied with Executive Order 12630 (53 FR 8859, March 15, 1988) by examining the takings implications of the rule in accordance with the “Attorney General's Supplemental Guidelines for the Evaluation of Risk and Avoidance of Unanticipated Takings” issued under the executive order. This proposed rule to grant conditional approval of West Virginia Emergency Rule 45CSR1 to meet Phase II of the NOX SIP Call does not impose an information collection burden under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).
