[EPA-R06-OAR-2006-0665; FRL-8528-1]
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.

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
NOX reductions.
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 NOX control 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
NOX reduction 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
NOX reductions 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.).
