Description: The goal is to lower emissions of NOx and other pollutants from diesel-powered motor
vehicles and nonroad equipment. It applies to diesel fuel
producers, importers, common carriers, distributors, transporters,
bulk terminal operators, and retailers. The rule covers 110
counties in the eastern half of Texas, including the ozone
nonattainment areas of Beaumont-Port Arthur, Dallas-Fort Worth, and
Houston-Galveston-Brazoria. The rule requires that diesel fuel as
defined under
30 TAC §114.6 produced for delivery and ultimate sale to
the consumer –for both on and nonroad use – must
contain less than 10 percent by volume of aromatic hydrocarbons and
must have a cetane number of 48 or greater. Some compliance options
are allowed.

Registration Requirements
All diesel producers and importers that sale or supply diesel
fuel into the 110 Texas counties affected by the TxLED regulations
are required to register with the TCEQ in accordance with
30 TAC §114.314. New producers and importers are required
to register with the TCEQ at least 30 days before they begin to
sell or supply diesel fuel into any of the 110 counties affected by
the TxLED regulations.
The TxLED Registration Form (
Word format,
PDF format) also includes instructions for completing the
forms. Registration forms submitted by individual companies contain
business confidential information and are not available for public
review. However, the
ID Summary available here provides a list of all producers and
importers currently registered with the TxLED program that includes
the company names, company ID numbers, and the city and state of
the registered TXLED companies.
Quarterly Reporting Requirements
Each producer and importer electing to sell, offer for sale,
supply, or offer to supply TxLED in accordance with
30 TAC §114.312 and
30 TAC §114.318 shall provide a quarterly summation report
to the executive director no later than the 45th day following the
end of the calendar quarter.
The reporting forms below are specific for each type of TxLED
compliance method.
Information requested in these reporting forms may be updated or
revised as new questions arise or further clarification is
needed.
Mail the completed quarterly reporting
form(s)to:

Draft Regulatory Guidance
Updated: March 13, 2008
The
draft regulatory guidance document (PDF) has been developed to
provide answers to common questions regarding the TxLED rules and
requirements and to assist producers, importers, and other affected
entities, with their compliance under these regulations. The
information contained in this draft regulatory guidance document
does not supercede or replace any state or federal laws or
regulations adopted by the TCEQ.
Approved Alternative Diesel Fuel Formulations
The following diesel fuels and/or diesel fuel additive blends
have been approved by the TCEQ as alternative diesel fuel
formulations for Texas Low Emission Diesel Fuel (TxLED) in
accordance with
30 TAC §114.315(c) or (d), and may be used to satisfy the
TxLED requirements as allowed under
30 TAC §114.312(f).
*
Alternative diesel formulations approved by the
California Air Resources Board (CARB) are also considered approved
by the TCEQ in accordance with
30 TAC §114.312(e). Therefore, the CARB certified diesel
fuel formulation, Executive Order G-714-031A, as issued to Kern Oil
& Refining Co. for its KOR-4c additive blended formulation is
acceptable for use as an alternative diesel fuel formulation for
TxLED.

CARB Certification
TxLED fuel standards may be satisfied by a CARB-certified
alternative diesel fuel formulation, or by fuel that complies with
certain California fuel regulations in accordance with
30 TAC §114.312(e). Please refer to the Draft Regulatory Guidance document for the
specific requirements.
Alternative Emission Reduction Plans
An alternative emission reduction plan (AERP) is the
documentation by which a diesel fuel producer demonstrates how a
substitute fuel strategy (or strategies) will achieve an equivalent
level of NOx emission reductions that otherwise would have been
achieved if they were producing TxLED through compliance with
30 TAC §114.312. The TxLED regulations under
30 TAC §114.318 specify the requirements that diesel fuel
producers must meet to use an AERP for compliance with the TxLED
fuel standards under
30 TAC §114.312.
Producers may use the
TxLED AERP Compliance Calculator (Excel format) and the AERP
Submittal Form (
Word format,
PDF format) to calculate and submit an AERP to the TCEQ that
demonstrates compliance with the AERP requirements under
30 TAC §114.318. The AERP submitted by individual
companies contain business confidential information and are not
available for public review.
The
TxLED AERP Compliance Calculator (Excel format) includes the
Unified Model and all of the other calculation formulas specified
under
30 TAC §114.318 to calculate compliance with the AERP
requirements.
Additional information about AERPs can be found in the Draft Regulatory Guidance document found on this
page.
