Approval and Promulgation of Air Quality Implementation Plans; Texas; Texas Low-Emission Diesel Fuel Program

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

SUMMARY: EPA is proposing to approve a revision to the State Implementation Plan (SIP) for the state of Texas. This revision makes changes to the Texas Low-Emission Diesel (TXLED) Fuel program. The revision establishes a replicable procedure for the State to approve Alternative Emission Reduction Plans (AERPs), extends the date of state approvals, and brings marine diesel fuels under the TXLED program. The revision also refines and clarifies testing requirements. The changes being proposed for approval positively influence the reductions of oxides of nitrogen (NOX) to be achieved. As a result and in accordance with section 110(l) of the Clean Air Act, 42 U.S.C. 7410(l), this revision will not interfere with attainment, reasonable further progress, or any other applicable requirement of the Clean Air Act.

DATES: Comments must be received on or before March 13, 2008.

What Action Are We Taking Today?

We approved the original TXLED rule on November 14, 2001, (66 FR 57196) in conjunction with the Houston-Galveston One-Hour Attainment Demonstration SIP. We also approved revisions to this rule on April 6, 2005 (70 FR 17321), and on October 6, 2005 (70 FR 58325). Today we are proposing to approve revisions to the TXLED rule submitted May 15, 2006, June 11, 2007, and June 13, 2007. Among other things, the revisions establish a replicable procedure for the State to evaluate Alternative Emission Reduction Plans (AERPs) so that changes to those plans do not have to be submitted to EPA as a SIP revision. Both EPA and the Texas Commission on Environmental Quality view this approach as a way to conserve resources. The revisions also extend the expiration date for state-approved AERPs and require two forms of marine diesel fuel to be subject to TXLED requirements. Other less substantive revisions are listed in the next section.

What Did the State Submit?

On May 15, 2006, the State submitted revisions to TXLED rules found in 30 TAC 114.6, 114.312, 114.313, 114.315, 114.316, 114.317, and 114.318. These revisions were adopted by the State on April 26, 2006. These include revisions to definitions; low emission diesel standards; designated alternate limits; approved test methods; monitoring, recordkeeping, and reporting requirements; exemption to low emission diesel requirements; and alternative emission reduction plans.

On June 11, 2007, the State submitted revisions adopted on May 9, 2007, to Sec. 114.318, Alternative Emission Reduction Plan. On June 13, 2007, the State submitted revisions adopted on May 23, 2007, to Sec. 114.6, Definitions, and to Sec. 114.319, Affected Counties and Compliance Dates.

Why Are These Revisions Approvable?

EPA finds that the TCEQ submittal meets the requirements of the CAA. We analyzed the rule revisions to ensure that they did not compromise the integrity of the approved SIP. Some changes were non- substantive editorial or format changes. Some substantive changes are considered minor. Major substantive changes are discussed below. A detailed analysis of all changes can be found in the Technical Support Document that accompanies this action.

Section 114.6. Definitions

The definition of additive is reworded for clarification. The definition of diesel fuel is expanded to include Diesel Marine fuel type X, also known as DMX, and Marine Gas Oil, also known as MGO. While these fuels do not share all fuel parameters with an EPA defined diesel fuel, EPA diesel and these marine fuels share many fuel parameters and are all light distillates. Because section 114.312(a) requires all ``diesel fuel'' to conform to TXLED standards or to an approved AERP, these marine fuels will now be subject to those requirements. Requiring these marine fuels to meet the TXLED requirements will cause these fuels to achieve the desired benefit, thereby ensuring further NOXreductions.

Section 114.312. Low Emission Diesel Standards

Volatile organic compounds (VOCs) were removed from the list of emissions that were required to be comparable to those of TXLED for alternative fuel formulation testing. This change was made to be consistent with changes made elsewhere in the rule. Because this rule is a NOXcontrol measure, and not intended to produce VOC reductions, and because VOC emissions from diesel engines are very small in any case, we propose to find approvable the removal of the VOC comparison requirement. Past SIP submittals for attainment, such as the Dallas-Fort Worth 1-hour attainment demonstration (April 2000) and the Houston 1-hour attainment demonstration (December 2000), do not contain values for and do not rely on VOC benefit from the TXLED program.

Section 114.315. Approved Test Methods

The State added specificity and clarity to the approved rules by making the following changes. The correlation equation to be used with ASTM Test Method D5186 is now specified. This equation is the same equation that appears in the EPA-approved CARB diesel rules. The adopted rule now requires the Executive Director to consult with and obtain agreement from EPA before the State approves an alternative to a test method. Additional fuel properties must be taken into consideration in characterizing the candidate fuel used in alternative fuel formulation testing. These include API gravity index, viscosity at 40 degrees C, flash point, and distillation in degrees F. Additional requirements that the test engine must meet are specified. The test engine must have a minimum specified amount of operation before initiating testing and must operate within 110% of its certified emission levels. An alternative test sequence, which EPA had not previously acted upon, was deleted from the rule. For a fuel to qualify as a TXLED fuel under the alternative fuel formulation portion of the rules, EPA must also be satisfied with the testing demonstration. These revisions are approvable because the changes make the rule more clear and provide for EPA involvement where necessary.

Section 114.316. Monitoring, Recordkeeping, and Reporting Requirements

Reporting on the additive used in an alternative fuel formulation is shifted from simply the amount used to a demonstration of how the emission reductions are achieved in the AERP. This strengthens the rule by making it more enforceable.

Section 114.318. Alternative Emission Reduction Plans

The AERP allows a diesel fuel producer to comply with the NOXreduction requirements of TXLED by employing an alternate fuel strategy. In the May 15, 2006, revision a replicable procedure is outlined that removes the requirement for all AERP changes to be approved by EPA with a SIP revision. The procedure describes in detail how a producer can meet the requirements of this section by complying with one or more methods laid out in this section of the rule. Several methods utilize credit for the early introduction of low sulfur gasoline. We had detailed discussions with the State and refiners to reach consensus on these methods. The amount of sulfur reduction from the early introduction of low sulfur gasoline is used to calculate the appropriate gasoline-to-diesel offset ratios. We find the replicable procedure presented in the SIP to be an approvable approach to handling changes to AERPs.

The June 11, 2007 revision extends the expiration date for state- approved AERPs from December 31, 2006 to December 31, 2007. The purpose of extending this date was to provide time for producers and vendors to complete testing of alternative fuel formulations and additives, which in turn would provide more options in the marketplace to comply with the rule requirements. We found that this date extension had no impact on the path to the 2009 attainment year. Therefore this date extension is approvable.

Section 114.319. Affected Counties and Compliance Dates

This section is amended to set a phased compliance schedule for the implementation of the marine diesel requirements. Producers and importers must comply by October 1, 2007, bulk distributors must comply by November

[[Page 8028]]

15, 2007, and retail dispensers and other affected persons must comply by January 1, 2008. Whereas all 110 counties are covered in this section, the revision covering marine fuels applies only to the HGB nonattainment area counties of Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery, and Waller.

Proposed Action

We are proposing approval of these revisions to the TXLED rule as submitted May 15, 2006, June 11, 2007, and June 13, 2007. The revisions being proposed for approval maintain the potential for the projected NOXreductions to be achieved. As a result, and in accordance with section 110(l) of the Act, 42 U.S.C. section 7410(l), these revisions will not interfere with attainment, reasonable further progress or any other applicable requirement of the Clean Air Act.

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 proposed 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 proposed 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 action 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 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 proposed 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 proposes to approve 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. This proposed 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 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. This proposed 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.).
