§1090.85 Explanatory terms.
This section explains how certain phrases and terms are used in this part, especially those
used to clarify and explain regulatory provisions. They do not, however, constitute specific
regulatory requirements and as such do not impose any compliance obligation on regulated
persons.
(a) Types of provisions. The term "provision" includes all aspects of the regulations in
this part. As described in this section, regulatory provisions include standards, requirements, and
prohibitions, along with a variety of other types of provisions. In certain cases, these terms apply
to some but not all the provisions of a part or section. For example, recordkeeping requirements
apply to jet fuel even though it is not subject to standards under this part.
(1)	A standard is a limit on the formulation, components, or characteristics of any fuel,
fuel additive, or regulated blendstock, established by regulation under this part. Compliance with
or conformance to a standard is a specific type of requirement, and in some cases a standard may
be discussed as a requirement. Thus, a statement about the requirements of a part or section also
applies with respect to the standards in the part or section. Examples of standards include the
sulfur per-gallon standards for gasoline and diesel fuel.
(2)	While requirements state what someone must do, prohibitions state what someone
may not do. Prohibitions are often referred to as prohibited acts. Failing to meet any requirement
that applies to a person under this part is a prohibited act.
(3)	The regulations in this part include provisions that are not standards, requirements, or
prohibitions, such as definitions.
Page 21 of 190

-------
(b)	A fuel is considered "subject to" a specific provision if that provision applies, even if
it falls within an exemption authorized under a different part of this regulation. For example,
gasoline is subject to the provisions of this part even if it is exempted from the standards under
subpart G of this part.
(c)	Singular and plural. Unless stated otherwise or unless it is clear from the regulatory
context, provisions written in singular form include the plural form and provisions written in
plural form include the singular form.
(d)	Inclusive lists. Lists in the regulations in this part prefaced by "including" or "this
includes" are not exhaustive. The terms "including" and "this includes" should be read to mean
"including but not limited to" and "this includes but is not limited to."
(e)	Notes. Statements that begin with "Note:" or "Note that" are intended to clarify
specific regulatory provisions stated elsewhere in the regulations in this part. By themselves,
such statements are not intended to specify regulatory requirements.
(f)	Examples. Examples provided in the regulations in this part are typically introduced
by either "for example" or "such as." Specific examples given in the regulations do not
necessarily represent the most common examples. The regulations may specify examples
conditionally (that is, specifying that they are applicable only if certain criteria or conditions are
met). Lists of examples cannot be presumed to be exhaustive lists.

covered area under the RFG program as required by 42 U.S.C. § 7545(k)(10)(D). The geographic
extent of each such covered area must be the nonattainment area boundaries as specified in 40
CFR part 81, subpart C, for the ozone NAAQS that was the subject of the reclassification.
(2)	Any classified ozone nonattainment area identified in 40 CFR part 81, subpart C, as
Marginal, Moderate, Serious, or Severe may be included as a covered area upon the request of
the governor of the state in which the area is located. EPA must:
(i)	Publish the governor's request in the Federal Register upon receipt.
(ii)	Establish an effective date that is not later than 1 year after the request is received
unless EPA determines that there is insufficient capacity to supply RFG as governed by 42
U.S.C. § 7545(k)(6)(A)(ii).
(3)	Any ozone attainment area in the ozone transport region established by 42 U.S.C. §
751 lc(a) may be included as a covered area upon petition by the governor of the state in which

(i)	Publish the governor's request in the Federal Register as soon as practicable after it is
received.
(ii)	Establish an effective date that is not later than 180 days after the request is received
unless EPA determines that there is insufficient capacity to supply RFG as governed by 42
U.S.C. § 7545(k)(6)(B)(iii).
(b)	Any area that opted into RFG under 42 U.S.C. § 7545(k)(6)(A) or (B) and has not
subsequently been reclassified as a Severe ozone nonattainment area may opt out of RFG using
the opt-out procedure in paragraph (d) of this section.
(c)	The governor of the state in which any covered area under 42 U.S.C. §
7545(k)(10)(D) is located may request that EPA remove the prohibition specified in 42 U.S.C. §
7545(k)(5) in such area by following the opt-out procedure specified in paragraph (d) of this
section upon one of the following:
(1)	Redesignation to attainment for such area for the most stringent ozone NAAQS in
effect at the time of redesignation.
(2)	Designation as an attainment area for the most stringent ozone NAAQS in effect at
the time of the designation. The area must also be redesignated to attainment for the prior ozone
NAAQS.
(d)	Procedure for opting out of RFG. (1) EPA may approve a request from a state asking
for removal of any RFG opt-in area, or portion of an RFG opt-in area, from inclusion as a
Page 48 of 190

-------
covered area listed in §1090.270(c) and (d), if it meets the requirements of paragraph (d)(2) of
this section. If EPA approves such a request, an effective date will be set as specified in
paragraph (d)(3) of this section. EPA will notify the state in writing of EPA's action on the
request and the effective date of the removal when the request is approved.
(2) An opt-out request must be signed by the governor of a state, or their authorized
representative, and must include all the following:
(1)	A geographic description of each RFG opt-in area, or portion of each RFG opt-in area,
which is covered by the request.
(ii)	A description of all ways in which emissions reductions from RFG are relied upon in
any approved SIP or any submitted SIP that has not yet been approved by EPA.
(iii)	For any RFG opt-in areas covered by the request where emissions reductions from
RFG are relied upon as specified in paragraph (d)(2)(ii) of this section, the request must include
all the following information:
(A)	Identify whether the state is withdrawing any submitted SIP that has not yet been
approved.
(B)(7)	Identify whether the state intends to submit a SIP revision to any approved SIP or
any submitted SIP that has not yet been approved, which relies on emissions reductions from
RFG, and describe any control measures that the state plans to submit to EPA for approval to
replace the emissions reductions from RFG.
(2)	A description of the state's plans and schedule for adopting and submitting any
revision to any approved SIP or any submitted SIP that has not yet been approved.
(C)	If the state is not withdrawing any submitted SIP that has not yet been approved and
does not intend to submit a revision to any approved SIP or any submitted SIP that has not yet
been approved, describe why no revision is necessary.
(iv)	The governor of a state, or their authorized representative, must submit additional
information upon request by EPA.
(3)(i)	Except as specified in paragraph (d)(3)(ii) of this section, EPA will set an effective
date of the RFG opt-out as requested by the governor, but no less than 90 days from EPA's
written notification to the state approving the RFG opt-out request.
(ii) Where emissions reductions from RFG are included in an approved SIP or any
submitted SIP that has not yet been approved, other than as a contingency measure consisting of
a future opt-in to RFG, then the effective date of the RFG opt-out in paragraph (d)(1) of this
section will be the date requested by the governor, but no less than 90 days from the effective
date of EPA approval of the SIP revision that removes the emissions reductions from RFG, and,
if necessary, provides emissions reductions to make up for those from RFG opt-out.

of the final transmix-blended gasoline following each occasion transmix is blended.
(2)	For transmix that is blended by a computer controlled in-line blending system, the
transmix blender must collect composite samples of the final transmix-blended gasoline at least
twice each calendar month during which transmix is blended. In-line samples may be collected
to comply with the requirements of this paragraph if the applicable requirements in paragraph
(d)(2) of this section are met.
(d)	Any transmix blender may petition EPA for approval of a quality assurance program
that does not include the minimum sampling and testing requirements in paragraph (c) of this
section. To seek approval for such an alternative quality assurance program, the transmix blender
must submit a petition to EPA that includes all the following:
Page 56 of 190

-------
(1)	A detailed description of the quality assurance procedures to be carried out at each
location where transmix is blended into PCG, including a description of how the transmix
blender proposes to determine the ratio of transmix that can be blended with PCG without
violating any of the applicable standards in this part, and a description of how the transmix
blender proposes to determine that the gasoline produced by the transmix blending operation

the submission is true to the best of their belief must accompany the petition.
(4)	Transmix blenders that petition EPA to use an alternative quality assurance program
must comply with any request by EPA for additional information or any other requirements that
EPA includes as part of EPA's evaluation of the petition. However, the transmix blender may
withdraw their petition or approved use of an alternative quality assurance program at any time,
upon notice to EPA.
(5)	EPA reserves the right to modify the requirements of an approved alternative quality
assurance program, in whole or in part, at any time, or withdraw approval of such an alternative
quality assurance program if EPA determines that the transmix blender's operation does not
effectively or adequately control, monitor, or document the end-point temperature of the gasoline
produced, or if EPA determines that any other circumstance exists that merits modification of the
requirements of an approved alternative quality assurance program. If EPA finds that a transmix
blender provided false or inaccurate information in any submission required under this section,
upon notification from EPA, the transmix blender's approval of an alternative quality assurance
program will be void ab initio.
(e) In the event that the test results for any sample collected under a quality assurance
program indicate that the gasoline does not comply with any of the applicable fuel quality
standards in this part, the transmix blender must do all the following:
(1)	Immediately take steps to stop the sale of the gasoline that was sampled.
(2)	Take steps that are reasonably calculated to determine the cause of the noncompliance
and to prevent future instances of noncompliance.

Subpart M—Sampling, Testing, and Retention Requirements
§1090.1300 General provisions.
(a)	This subpart is organized as follows:
(1)	Sections 1090.1310 through 1090.1330 specify the scope of required testing,
including special provisions that apply in several unique circumstances.
(2)	Sections 1090.1335 through 1090.1345 specify handling procedures for collecting and
retaining samples. Sections 1090.1350 through 1090.1375 specify the procedures for measuring
the specified parameters. These procedures apply to anyone who performs testing under this
subpart.
(3)	Section 1090.1395 specifies the procedures for testing related to gasoline deposit
control test procedure.
(b)	If you need to meet requirements for a quality assurance program at some minimum
frequency, your first batch of product triggers the testing requirement. The specified frequency
serves as a deadline for performing the required testing, and as a starting point for the next
testing period. The following examples illustrate the requirements for testing based on sampling
the more frequent of every 90 days or 500,000 gallons of certified butane you received from a
supplier:
(1)	If your testing period starts on March 1 and you use less than 500,000 gallons of
butane from March 1 through May 29 (90 days), you must perform testing under a quality
assurance program sometime between March 1 and May 29. Your next test period starts with the
use of butane on May 30 and again ends after 90 days or after you use 500,000 gallons of butane,
whichever occurs first.
(2)	If your testing period starts on March 1 and you use 500,000 gallons of butane for the
testing period on April 29 (60 days), you must perform testing under a quality assurance program
sometime between March 1 and April 29. Your next testing period starts with the use of butane
on April 30 and again ends after 90 days or after you use 500,000 gallons of butane, whichever
occurs first.
(c)	Anyone performing tests on behalf of a manufacturer to demonstrate compliance with
standards or other requirements under this part must meet the requirements of this subpart in the
same way that the manufacturer needs to meet requirements for its own testing.
(d)	Anyone performing tests under this subpart must apply good laboratory practices for
all sampling, measurement, and calculations related to testing required under this part. This
requires performing these procedures in a way that is consistent with generally accepted
scientific and engineering principles and properly accounting for all available relevant
information.
(e)	Subpart P of this part has provisions related to importation, including provisions that
describe how to meet the sampling and testing requirements of this subpart.
Page 126 of 190

-------
(f) The following general provisions apply:
(1)	A crosscheck program is an arrangement for laboratories to perform measurements
from test samples prepared from a single homogeneous fuel batch to establish an accepted
reference value for evaluating precision and accuracy. This subpart relies on inter-laboratory
crosscheck programs sponsored by ASTM International or another voluntary consensus
standards body, or on crosscheck programs conducted separately by one or more companies.
(2)	A voluntary consensus standards body is an organization that follows consistent
protocols to adopt standards reflecting a wide range of input from interested parties. ASTM
International and the International Organization for Standardization are examples of VCSB
organizations.
SCOPE OF TESTING
§1090.1310 Testing to demonstrate compliance with standards.
(a)	Perform testing as needed to submit the reports specified in subpart J of this part. This
section specifies additional test requirements.
(b)	Fuel manufacturers must perform the following measurements before the fuel, fuel
additive, or regulated blendstock from a given batch leaves the fuel manufacturing facility,
except as specified in §1090.1315:
(1)	Diesel fuel. Perform testing for each batch of ULSD, 500 ppm LM diesel fuel, and
ECA marine fuel to demonstrate compliance with sulfur standards.
(2)	Gasoline. Perform testing for each batch of summer gasoline to demonstrate
compliance with RVP standards, and to demonstrate compliance with sulfur standards for both
summer and winter gasoline.
(c)	The following testing provisions apply for gasoline and regulated gasoline

parameters (i.e., T10, T50, T90, final boiling point, and percent residue) in addition to other
measurements to demonstrate compliance with applicable standards.
§1090.1315 In-line blending.
Fuel manufacturers using in-line blending equipment may qualify for a waiver from the
requirement in §1090.1310(b) to test every batch of fuel before the fuel leaves the fuel
manufacturing facility as follows:
(a)	The waiver in this section applies if you use or intend to use in-line blending
equipment to supply fuel directly into a pipeline, marine vessel, or other type of distribution that
does not involve collecting fuel in a tank or other type of storage for creating a batch of fuel. It
also applies for fuel manufacturers that produce batches of fuel that are too large to contain in
available storage tanks.
(b)	Waivers granted under 40 CFR part 80 are no longer valid. Any party who received
an in-line blending waiver granted under 40 CFR part 80 may continue to operate under the
waiver for 60 days after the effective date of this part. To request a waiver, send EPA a request
signed by the RCO with the following information:
(1)	Describe the location of your in-line blending operation, how long it has been in
operation, and how much of each type and grade of fuel you have blended over the preceding 3
years (or since starting the in-line blending operation if that is less than 3 years). Describe the
physical layout of the blending operation and how you move the blended fuel into distribution.
Also describe how your automated system monitors and controls blending proportions and the
properties of the blended fuel. For new installations, describe these as a planned operation with
projected volumes by type and grade.
(2)	Describe how you collect and test composite fuel samples in a way that is equivalent
to measuring the fuel properties of a batch of blended fuel as specified in this subpart. Your
procedures need to conform to the sampling specifications in ASTM D4177 and the composite
calculations in ASTM D5854 (both incorporated by reference in §1090.95).
Page 128 of 190

-------
(3)	Describe any expectation or plan for you or another party to perform additional
downstream testing for the same fuel parameters.
(4)	Describe your quality assurance procedures. Describe any experiences from the
previous 3 years where these quality assurance procedures led you to make corrections to your
in-line blending operation.
(5)	Describe any times from the previous 3 years that you modified fuel after it came out
of your blending operation. Describe how you modified the fuel and why that was necessary.
(6)	Describe how you will meet the auditing requirements of paragraph (c) of this section.
(c)	You must arrange for an audit of your blending operation each calendar year that
reviews procedures and documents to determine whether measured and calculated values
properly represent the aggregate fuel properties for the blended fuel.
(d)	You must update your in-line blending waiver request 60 days prior to making any
material change to your in-line blending process.
(e)	If we approve your request for a waiver under this section, we may require you to
update your procedures for more effective control and documentation of measured fuel
parameters based on audit results, development of improved practices, or other information.
§1090.1320 Adding blendstock to PCG.
The requirements of this section apply for refiners and blending manufacturers that add
blendstock to PCG to produce a new batch of gasoline. Paragraph (c) of this section specifies an
optional alternative approach for certified butane and certified pentane blenders. Section
1090.1325 describes additional provisions that apply to transmix processors.
(a) Sample and test using one of the following methods to exclude PCG from the
compliance demonstration for sulfur and benzene:
(1) Compliance by subtraction, (i) Sample and test the sulfur and benzene content of each
batch of PCG before blending blendstocks to produce a new batch of gasoline.
(ii)	Determine the volume of PCG that was blended with blendstock to produce a new
batch of gasoline. Report the PCG as a negative batch as specified in §1090.905(c)(3)(i).
(iii)	After adding blendstock to PCG, sample and test the sulfur and benzene content of
the new batch of gasoline.
(iv)	Determine the volume of the new batch of gasoline. Report the new batch of gasoline
as a positive batch as specified in §1090.905(c)(3)(ii).
(v)	Include the PCG batch and the new batch of gasoline in compliance calculations as
specified in §1090.700(d)(4)(i).
Page 129 of 190

-------
(vi) The sample-retention requirements in §1090.1345 apply for both the new batch of
gasoline and the associated PCG.
(2) Compliance by addition, (i) Sample and test the sulfur and benzene content of each
batch of blendstock used to produce a new batch of gasoline from PCG.
(ii)	Determine the volume of each batch of blendstock used to produce the new batch of
gasoline.
(iii)	Report each batch of blendstock as specified in §1090.905(c)(4).
(iv)	Include each batch of blendstock in compliance calculations as specified in
§ 1090.700(d)(4)(ii).
(v)	The sample-retention requirements in §1090.1345 apply for the new batch of gasoline
and for each blendstock.
(b)	Regardless of which approach is used under paragraph (a) of this section,
manufacturers must determine the volume of each blended batch of gasoline, and perform the
following measurements for each blended batch of gasoline using the procedures specified in
§1090.1350:
(1)	Measure sulfur content, benzene content, oxygenate content, and for summer
gasoline, RVP.
(2)	Determine the following distillation parameters: T10, T50, T90, final boiling point,
and distillation residue.
(c)	Certified butane or certified pentane blenders that blend certified butane or certified
pentane into PCG to make a new batch of gasoline may meet the sampling and testing
requirements of this subpart instead of the requirements of paragraphs (a) and (b) of this section
if the certified butane blender or certified pentane blender does all of the following:
(1)	For summer gasoline, measure RVP of the blended fuel. The fuel manufacturer may
rely on sulfur and benzene test results from the certified butane or certified pentane producer.
Note that § 1090.245(e) disallows adding certified butane and certified pentane to RFG.
(2)	Before blending the certified butane or certified pentane with PCG, obtain a copy of
the producer's test results indicating that the certified butane or certified pentane meets the
standards in §1090.220 or §1090.225, respectively.
(3)	The certified pentane blender must enter into a contract with the certified pentane
producer to verify that the pentane producer has an adequate quality assurance program to ensure
that the certified pentane received will not be contaminated in transit.
(4)	The certified butane or certified pentane blender must conduct a quality assurance
program to demonstrate that the butane or pentane has the properties specified in §1090.220 or
§1090.225. The quality assurance program must be based on sampling the more frequent of
Page 130 of 190

-------
every 90 days or 500,000 gallons of certified butane or certified pentane received from each
producer. The certified butane or certified pentane blender may rely on a third party to perform
the testing.
§1090.1325 Adding blendstock to TGP.
The following provisions apply to transmix processors producing gasoline by adding
blendstock to TGP:
(a)	Perform testing for each batch of summer gasoline to demonstrate compliance with
the applicable RVP standard in §1090.215.
(b)	Measure the distillation endpoint for gasoline you produce from TGP as specified in
§1090.1350.
(c)	Determine the volume, sulfur content, and benzene content of each blendstock batch

and testing as specified in §1090.1320 and treating the TGP used to produce the gasoline as
PCG.
(d)	Sample and test the gasoline made from TGP and blendstock blend to demonstrate
compliance with the 80 ppm sulfur per-gallon standard in § 1090.205(b) and the applicable RVP
standard in §1090.215.
(e)	Transmix processors producing gasoline by adding TGP to PCG do not have to
measure oxygenate in the finished gasoline if the records for each these of blendstocks show no
oxygenate content.
(f)	Transmix processors do not have to measure benzene in finished gasoline if the
finished gasoline includes nothing other than TGP and PCG.
§1090.1330 Preparing denatured fuel ethanol.
DFE producers and importers may calculate the sulfur content of a batch of DFE instead
of measuring every batch as follows:
(a)	Determine the sulfur content of ethanol before adding denaturant by measuring it as
specified in §1090.1310 or by estimating it based on your production quality control procedures.
(b)	Use the ppm sulfur content of certified ethanol denaturant specified by a registered
supplier based on the appropriate PTD. If the sulfur content is specified as a range, use the
maximum specified value.
(c)	Calculate the weighted sulfur content of the DFE from the values determined under
paragraphs (a) and (b) of this section.

-------
HANDLING AND PREPARING SAMPLES
§1090.1335 Collecting and preparing samples for testing.
(a)	General provisions. Use good laboratory practice to collect samples to represent the
batch you are testing. For example, always take steps to prevent sample contamination, such as
completely flushing sampling taps and piping and pre-rinsing sample containers with the product
being sampled. Perform manual sampling as specified in paragraph (b) of this section, or perform
automatic sampling as specified in paragraph (c) of this section.
(b)	Manual sampling. Perform manual sampling using one of the methods specified in
ASTM D4057 (incorporated by reference in §1090.95) as follows:
(1)	Use tap sampling or spot sampling to collect upper, middle, and lower samples.
Adjust sampling for partially filled tanks as shown in Table 1 of ASTM D4057. If you test all the
samples for a given fuel parameter, calculate the arithmetic average of the test results to
represent the batch; otherwise, you may use the test result from a single sample to represent the
batch. Do not create a composite sample from the separate samples.
(2)	Collect a "running" or "all-levels" sample from the top of the tank with no standpipe.
Drawing a sample from a standpipe is acceptable only if it is slotted or perforated to ensure that
the drawn sample properly represents the whole batch of fuel.
(3)	If the procedure in paragraphs (b)(1) and (2) of this section are impractical for a given
storage configuration, you may use alternative sampling procedures as specified in ASTM
D4057. This applies mostly for sampling with trucks, railcars, retail stations, and other
downstream locations.
(4)	Test results with manual sampling are valid only after you demonstrate homogeneity
as specified in §1090.1337, with the following exceptions:
(i)	The homogeneity testing requirement does not apply at downstream locations if it is
not possible to collect separate samples and you take steps to ensure that the batch is well mixed.
(ii)	You may disregard the homogeneity demonstration if you test each drawn sample for
every parameter subject to a testing requirement and use the highest (or worst-case) test result for
each parameter. This applies for meeting per-gallon and average standards and all other aspects
of compliance.
(c)	Automatic sampling. Perform automatic sampling as specified in ASTM D4177
(incorporated by reference in §1090.95). Configure the system to ensure a well-mixed stream at
the sampling point. Calculate the number of grab samples for a given batch based on a margin of
error of 0.03 and a 95 percent confidence level. Take steps to align the start and end of sampling
with the start and end of creating the batch.
(d)	Sampling provisions related to measuring RVP of summer gasoline. The following
additional provisions apply for preparing samples to measure RVP of summer gasoline:
Page 132 of 190

-------
(1)	Meet the additional specifications for manual and automatic sampling in ASTM
D5842 (incorporated by reference in §1090.95).
(2)	If you measure RVP for multiple test samples to demonstrate compliance, do not
calculate an average result. Rather, each tested sample must meet the RVP standard that applies.
(3)	If you measure other fuel parameters for a given sample in addition to RVP testing,
always measure RVP first.
§1090.1337 Demonstrating homogeneity.
(a)	Use the procedures in this section as specified in §1090.1335 to determine whether a
batch is homogeneous and suitable for parameter measurements under this subpart. If the batch is
not homogeneous, increase mixing or take other appropriate steps and repeat the procedure.
(b)	Draw a sample representing different tank segments of the stored fuel, fuel additive,
or regulated blendstock as specified in §1090.1335(b). Consider the stored fuel to be
homogeneous without testing for upright cylindrical tanks if the liquid depth (from the tank
outlet) is less than 35 percent of the tank diameter.
(c)	For testing to meet the gasoline standards in subpart C of this part, demonstrate
homogeneity using two of the procedures specified in paragraph (c)(1) through (4) of this
section. For summer gasoline, the homogeneity demonstration must include RVP measurements.
(1)	Measure API gravity from each sample using ASTM D287, ASTM D1298, or ASTM
D4052 (incorporated by reference in §1090.95).
(2)	Measure sulfur from each sample as specified in this subpart.
(3)	Measure RVP from each sample as specified in this subpart.
(4)	Measure benzene from each sample as specified in this subpart.
(d)	For testing to meet the diesel fuel standards in subpart D of this part, demonstrate
homogeneity using either of the procedures specified in paragraph (c)(1) or (2) of this section.
(e)	Consider the fuel batch to be homogeneous for a given parameter if the measured
values for all tested samples vary by less than the published repeatability of the test method. If
repeatability is a function of measured values, calculate repeatability using the average value of
the measured parameter representing all tested samples. Calculate using the full precision
specified for the test method, even if §1090.1350(c) describes a different precision.
§1090.1340 Preparing hand-blend samples from BOB.
(a) If you produce or import BOB and instruct downstream blenders to add oxygenate,
you must meet the sampling requirements of this subpart by blending oxygenate into a BOB
sample to represent the final blended fuel. To do this, prepare each fuel sample by adding
Page 133 of 190

-------
oxygenate to the BOB sample in a way that corresponds to your instructions to downstream
blenders for the sampled batch of fuel. Prepare a worst-case hand blend sample as follows:
(1)	Take steps to avoid introducing high or low bias in sulfur content when selecting from
available samples to create the hand blend. For example, if there are three samples with discrete
sulfur measurements, select the sample with the mid-range sulfur content. In other cases,
randomly select the sample.
(2)	If your instructions allow for downstream blenders to add more than one type or
concentration of oxygenate, prepare a hand blend sample for summer gasoline intended for
blending with ethanol using the lowest specified ethanol blend. For summer gasoline intended
for blending only with oxygenate other than ethanol, and for all winter gasoline, blend at the
lowest specified oxygenate concentration, regardless of the type of oxygenate. For example, if
you give instructions for a given batch of BOB to perform downstream blending to make E10,
El5, and an 8 percent blend with butanol, prepare a hand blend for testing winter gasoline with 8
percent butanol, and prepare an E10 hand blend for testing summer gasoline.
(b)	Blend the fuel using the procedures specified in ASTM D7717 (incorporated by
reference in §1090.95). The blended fuel must have an amount of oxygenate that is within 0.1
volume percent of the oxygenate concentration specified on the PTD for the BOB under
§1090.1160(b)(1) . For example, anElOblend must have 10.0±0.1 percent oxygenate.
(c)	If you produce or import BOB and you blend in oxygenate before selling or
transporting the fuel, you must instead draw samples from your blended fuel.
§1090.1345 Retaining samples.
(a) Fuel manufacturers, regulated blendstock producers, and independent surveyors must
retain samples of fuel and regulated blendstocks tested under this subpart as follows:
(1)	If you test gasoline or diesel fuel as required under this subpart, you must keep a
representative fuel sample for at least 30 days after testing is complete, except that a longer
sample retention of 120 days applies for blending manufacturers that either produce or modify
gasoline.
(2)	The nominal volume of retained samples must be at least 330 ml. If you have only a
single sample for testing, keep that sample after testing is complete. If you collect multiple
samples from a single batch or you create a hand-blended sample, select a representative sample
as follows:
(i)	If you test hand-blended mixtures of BOB and oxygenate under §1090.1340, keep a
sample of the BOB. You may also keep a corresponding sample of either the blended fuel or a
sample of the oxygenate for again creating a sample of blended fuel. If you do not keep a sample
of the blended fuel or an oxygenate sample, testing with the retained BOB sample may include
blending with any appropriate oxygenate.
(ii)	For summer gasoline, keep an untested (or less tested) sample that is most like the
tested sample, as applicable. In all other cases, keep the tested (or most tested) sample.
Page 134 of 190

-------
(b)	Oxygenate producers and importers must keep oxygenate samples as follows:
(1)	Keep a representative sample of any tested oxygenate. Also keep a representative
sample of DFE if you used the provisions of §1090.1330 to calculate its sulfur content. The
nominal volume of retained samples must be at least 330 ml.
(2)	Keep all the samples you collect over the previous 21 days. If you have fewer than 20
samples from the previous 21 days, continue keeping the most recent 20 samples collected up to
a maximum of 90 days for any given sample.
(c)	Keep a record of all calculations, test results, and test methods for the batch associated
with each stored sample.
(d)	If we ask for a test sample, you must follow our instructions and send it to EPA by a
courier service (or equivalent). The instructions will describe where and when to send the
sample. You must identify the test results and test methods along with each test sample.
(e)	You are responsible for meeting requirements of this section even if a third party
performs testing and stores the fuel samples for you.
MEASUREMENT PROCEDURES
§1090.1350 Overview of test procedures.
Fuel manufacturers meet the requirements of this subpart based on laboratory
measurements of the specified fuel parameters. Test procedures for these measurements apply as
follows:
(a)	The Performance-based Measurement System specified in §§1090.1360 through
1090.1375 applies for all testing specified in this subpart for the following fuels and fuel
parameters, except as specified in paragraph (b) of this section:
(1)	Sulfur content of diesel fuel.
(2)	Sulfur content of EC A marine fuel.
(3)	RVP, sulfur, benzene, and oxygenate content of gasoline. The procedures for
measuring sulfur in gasoline in this subpart also apply for testing sulfur in certified ethanol
denaturant; however, demonstrating compliance for alternative procedures in §1090.1365 and
statistical quality control in §1090.1375 do not apply for sulfur concentration above 80 ppm.
(4)	Sulfur in butane.
(b)	Specific test procedures apply for measuring other fuel parameters, as follows:
(1) Determine the cetane index of diesel fuel as specified in ASTM D976 or ASTM
D4737 (incorporated by reference in §1090.95). There is no cetane-related test requirement for
biodiesel.
Page 135 of 190

-------
(2)	Measure aromatic content of diesel fuel as specified in ASTM D1319 or ASTM
D5186 (incorporated by reference in §1090.95). You may use an alternative procedure if you
correlate your test results with ASTM D1319 or ASTM D5186.
(3)	Measure the purity of butane and pentane as specified in ASTM D2163 (incorporated
by reference in §1090.95).
(4)	Measure benzene in butane and pentane as specified in ASTM D5134 (incorporated
by reference in §1090.95).
(5)	Measure sulfur in pentane as specified in ASTM D6667 (incorporated by reference in
§1090.95).
(6)	Measure distillation parameters of gasoline as specified in ASTM D86 (incorporated
by reference in §1090.95). You may use an alternative procedure if you correlate your test results
with ASTM D86.
(7)	Measure the sulfur content of neat ethanol as specified in ASTM D5453 (incorporated
by reference in §1090.95). You may use an alternative procedure if you correlate your test results
with ASTM D5453.
(8)	Measure the phosphorus content of gasoline as specified in ASTM D3231
(incorporated by reference in §1090.95).
(9)	Measure the lead content of gasoline as specified in ASTM D3237 (incorporated by
reference in §1090.95).
(10)	Measure the sulfur content of gasoline additives and diesel fuel additives as
specified in ASTM D2622 (incorporated by reference in §1090.95).
(11)	[Reserved]
(12) Use referee procedures specified in §1090.1360(d) and the following additional
methods to measure gasoline fuel parameters to meet the survey requirements of subpart N of
this part:

1 ASTM specifications are incorporated by reference in §1090.95.
(13) Updated versions of the test procedures specified in this section are acceptable as
alternative procedures if both repeatability and reproducibility are the same as or better than the
values specified in the earlier version.
(c) Record measured values with the following precision, with rounding as appropriate:
Page 136 of 190

-------
(1)	Record sulfur content to the nearest whole ppm.
(2)	Record benzene to the nearest 0.01 volume percent.
(3)	Record RVP to the nearest 0.01 psi.
(4)	Record oxygenate content to the nearest 0.01 mass percent for each calibrated
oxygenate.
(5)	Record diesel aromatic content to the nearest 0.1 volume percent, or record cetane
index to the nearest whole number.
(6)	Record gasoline aromatic and olefin content to the nearest 0.1 volume percent.
(7)	Record distillation parameters to the nearest whole degree.
(d) For any measurements or calculations that depend on the volume of the test sample,
correct the volume of the sample to a reference temperature of 15.5 °C (288.65 K). Use a
correction equation that is appropriate for each tested compound. This applies for all fuels,
blendstocks, and additives, except butane.
§1090.1355 Calculation adjustments and corrections.
Adjust measured values for special circumstances as follows:
(a)	Adjust measured values for total vapor pressure using the following equation:
RVP (psi) = 0.956 • Ptotal - 0.347
Where:
Ptotal = Measured total vapor pressure, in psi.
(b)	For measuring sulfur and benzene in gasoline, adjust a given test result upward in
certain circumstances, as follows:
(1)	If your measurement method involves a published procedure with a Pooled Limit of
Quantitation (PLOQ), treat the PLOQ as your final result if your measured result is below the
PLOQ.
(2)	If your measurement method involves a published procedure with a limited scope but
no PLOQ, treat the lower bound of the scope as your final result if your measured result is less
than that value.
(3)	If you establish a Laboratory Limit of Quantitation (LLOQ) below the lower bound of
the scope of the procedure as specified in ASTM D6259 (incorporated by reference in §1090.95),
treat the LLOQ as your final result if your measured result is less than the LLOQ. Note that this
option is meaningful only if the LLOQ is less than a published PLOQ, or if there is no published
PLOQ.
Page 137 of 190

-------
(c)	For measuring benzene in butane and pentane, report a zero value if the test result is at
or below the Pooled Limit of Quantitation or Limit of Detection that applies for the test method.
(d)	If measured content of any oxygenate compound is less than 0.1 percent by mass,
record the result as "None detected."
§1090.1360 Performance-based Measurement System.
(a)	The Performance-based Measurement System is an approach that allows for
laboratory testing with any procedure that meets specified performance criteria. This subpart
specifies the performance criteria for measuring certain fuel parameters to demonstrate
compliance with the standards and other specifications of this part. These provisions do not
apply to process stream analyzers used with in-line blending.
(b)	Different requirements apply for absolute fuel parameters and method-defined fuel
parameters. An absolute fuel parameter is one for which it is possible to evaluate measurement
accuracy by comparing measured values of a test sample to a reference sample with a known
value for the measured parameter. Sulfur is currently the only absolute fuel parameter. This
applies for measuring sulfur in any fuel, fuel additive, or regulated blendstock. Method-defined
fuel parameters are all those that are not absolute fuel parameters. Additional test provisions
apply for method-defined fuel parameters under this section because there is no reference sample
for evaluating measurement accuracy.
(c)	The performance criteria of this section apply as follows:
(1)	Section 1090.1365 specifies the initial qualifying criteria for all measurement
procedures. You may use an alternative procedure only if testing shows that you meet the initial
qualifying criteria
(2)	Section 1090.1375 specifies ongoing quality testing requirements that apply for
laboratories that use either referee procedures or alternative procedures.
(3)	Streamlined requirements for alternative procedures apply for procedures adopted by
a voluntary consensus standards body (VCSB). Compliance testing with non-VCSB procedures
requires our advance approval. Procedures are considered non-VCSB testing as follows:
(i)	Procedures developed by individual companies or other parties are considered "non-
VCSB" procedures.
(ii)	Draft procedures under development by a VCSB organization are considered non-
VCSB procedures until they are approved for publication.
(iii)	A published procedure is considered non-VCSB for testing with fuel parameters that
fall outside the range of values covered in the research report of the ASTM D6708 (incorporated
by reference in §1090.95) assessment comparing candidate alternative procedures to the referee
procedure specified in paragraph (d) of this section.
Page 138 of 190

-------
(4)	You may qualify updated versions of the referee procedures as alternative procedures
under §1090.1365. You may ask EPA for approval to use an updated version of the referee
procedure for qualifying other alternative procedures if the updated referee procedure has the
same or better accuracy and precision compared to the version specified in §1090.95. If the
updated procedure has worse accuracy and precision compared to the earlier version, you must
complete the required testing specified in §1090.1365 using the older, referenced version of the
referee procedure.
(5)	The Performance-based Analytical Test Method in 40 CFR 80.47 waived precision
and accuracy demonstrations for laboratories that had been using the specified referee procedure
before October 28, 2013. The protocol for qualifying test procedures in this subpart includes no
such "grandfather" date, which means that any laboratory may use the specified referee
procedure without qualification testing. To use alternative procedures at a given facility, you
must perform the specified testing to demonstrate compliance with precision and accuracy
requirements, with the following exceptions:
(i)	Testing you performed to qualify alternative procedures under 40 CFR part 80
continues to be valid for making the demonstrations we require in this part.
(ii)	Qualification testing is not required for laboratories that measure benzene in gasoline
using Procedure B of ASTM D3606 (incorporated by reference in §1090.95). However,
qualification testing may be necessary for updated versions of this procedure as specified in
§1090.1365(a)(2).
(d) Referee procedures are presumed to meet the initial qualifying criteria in this section.
You may use alternative procedures if you qualify them using the referee procedures as a
benchmark as specified in §1090.1365. The following are the referee procedures:

§1090.1365 Qualifying criteria for alternative measurement procedures.
This section specifies how to qualify alternative procedures for measuring absolute and
method-defined fuel parameters under the Performance-based Analytical Test Method specified
in §1090.1360.
(a) The following general provisions apply for qualifying alternative procedures:
Page 139 of 190

-------
(1)	Alternative procedures must have appropriate precision to allow for reporting to the
number of decimal places specified in §1090.1350(c).
(2)	Testing to qualify an alternative procedure applies for the specified version of the
procedure you use for making the necessary measurements. Once an alternative procedure for a
method-defined fuel parameter is qualified for your laboratory, updated versions of that same
procedure are qualified without further testing, as long as the procedure's specified
reproducibility is the same as or better than the values specified in the earlier version. For
absolute fuel parameters, updated versions are qualified without testing if both repeatability and
reproducibility are the same as or better than the values specified in the earlier version.
(3)	Except as specified in paragraph (d) of this section, testing to demonstrate compliance
with the precision and accuracy specifications in this section apply only for the test facility
where the testing occurred.
(4)	If a procedure for measuring benzene or sulfur in gasoline has no specified Pooled
Limit of Quantitation and no specified scope with a lower bound, you must establish a
Laboratory Limit of Quantitation for your facility.
(5)	Testing for method-defined fuel parameters must take place at a reference installation
as specified in §1090.1370.
(b) All alternative procedures must meet precision criteria based on a calculated
maximum allowable standard deviation for a given fuel parameter as specified in this paragraph.
The precision criteria apply for measuring the parameters and fuels specified in paragraph (b)(3)
of this section. Take the following steps to qualify the measurement procedure for measuring a
given fuel parameter:
(1)	The fuel must meet the parameter specifications in Table 1 to this section. This may
require that you modify the fuel you typically produce to be within the specified range. Absent a
specification (maximum or minimum), select a fuel representing values that are typical for your
testing. Store and mix the fuel to maintain a homogenous mixture throughout the measurement
period to ensure that each fuel sample drawn from the batch has the same properties.
(2)	Measure the fuel parameter from a homogeneous fuel batch at least 20 times. Record
each result in sequence. Do not omit any valid results unless you use good engineering judgment
to determine that the omission is necessary and you document those results and the reason for
excluding them. Perform this analysis over a 20-day period. You may make up to 4 separate
measurements in a 24-hour period, as long as the interval between measurements is at least 4
hours. Do not measure RVP more than once from a single sample.
(3)	Calculate the maximum allowable standard deviation, omax using the following
equation:
*2
°max — X1 '
x3
Where xi, X2, and X3 have the values from the following table:

1	Calculate repeatability and reproducibility using the average value determined from testing. Use units as specified
in §1090.1350(c).
2	ASTM publications are incorporated by reference in § 1090.95. Note that the listed procedure may be different than
the referee procedure identified in § 1090.1360(d), or it may be an older version of the referee procedure.
3	Use only 1-liter containers for testing to qualify alternative methods.
(c) Alternative VCSB procedures for measuring absolute fuel parameters (sulfur) must
meet accuracy criteria based on the following measurement procedure:
(1)	Obtain a gravimetric sulfur standard to serve as representative reference samples. The
samples must have known sulfur content within the ranges specified in paragraph (c)(3) of this
section. The known sulfur content is the accepted reference value (ARV) for the fuel sample.
(2)	Measure the sulfur content of the fuel sample at your laboratory at least 10 times,
without interruption. Use good laboratory practice to compensate for any known chemical
interferences; however, you must apply that same compensation for all tests to measure sulfur
content in a test fuel. Calculate the arithmetic average of all the measured values, including any
compensation.
(3)	The measurement procedure meets the accuracy requirement as follows:
(i) Demonstrate accuracy for measuring sulfur in gasoline, regulated gasoline blendstock,
and gasoline fuel additives using test fuels to represent sulfur values from 1 to 10 ppm, 11 to 20
ppm, and 21 to 95 ppm. You may omit any of these ranges if you do not perform testing with
fuel in that range. Calculate the maximum allowable difference between the average measured
value and ARV for each applicable range using the following equation:
Maximum Allowable Difference = 0.75- omax
Page 141 of 190

-------
Where,
Gmax = the maximum allowable standard deviation from paragraph (b)(3) of this section
using the sulfur content represented by ARV.
(ii) Demonstrate accuracy for measuring sulfur in diesel fuel using test fuels meeting the
specifications in Table 2 to this section. For testing diesel-related blendstocks and additives, use
representative test samples meeting the appropriate sulfur specification. Table 2 to this section
also identifies the maximum allowable difference between average measured values and ARV
corresponding to ARV at the upper end of the specified ranges. These values are based on
calculations with the equation in paragraph (c)(3)(i) of this section, with parameter values set to
be equal to the standard.

(d)	Alternative VCSB procedures for measuring method-defined fuel parameters must
meet accuracy criteria as follows:
(1)	You may use the alternative procedure only if you follow all the statistical protocols
and meet all the criteria specified in Section 6 of ASTM D6708 (incorporated by reference in
§1090.95) when comparing your measurements using the alternative procedure to measurements
at a reference installation using the appropriate referee test method identified in §1090.1360(d).
(2)	For qualifying alternative procedures, determine whether the alternative procedure
needs a correlation equation to correct bias relative to the reference test method. Create such a
correlation equation as specified in Section 7 of ASTM D6708 (incorporated by reference in
§1090.95). For all testing, apply the correlation equation to adjust measured values to be
statistically consistent to measuring with the reference test method.
(3)	If an alternative VCSB procedure states that the procedure has a successful
assessment relative to the referee procedures in this section under ASTM D6708, that finding
applies for all test facilities using that procedure.
(e)	Alternative non-VCSB procedures for measuring absolute fuel parameters (sulfur)
must meet accuracy criteria as follows:
(1) Demonstrate whether the procedure meets statistical criteria and whether it needs a
correlation equation as specified in paragraphs (d)(1) and (2) of this section. Apply the
correlation equation for all testing with the alternative procedure.
Page 142 of 190

-------
(2)	Demonstrate at your laboratory that the alternative procedure meets the accuracy
criteria specified in paragraph (c) of this section.
(3)	Send EPA a written request to use the alternative procedure. In your request, fully
describe the procedure to show how it functions for achieving accurate measurements and
include detailed information related to your assessment under paragraph (d)(1) and (2) of this
section. We will approve your request if your alternative procedure meets the specified
requirements.
(f) Alternative non-VCSB procedures for measuring method-defined fuel parameters
must meet accuracy and precision criteria as follows:
(1)	Demonstrate whether the procedure meets statistical criteria and whether it needs a
correlation equation as specified in paragraphs (d)(1) and (2) of this section. Apply the
correlation equation for all testing with the alternative procedure.
(2)	Test with a range of fuels that are typical of those you will analyze at your laboratory.
Use either consensus-named fuels or locally-named reference materials. Consensus-named fuels
are homogeneous fuel quantities sent around to different laboratories for analysis, which results
in a "consensus name" representing the average value of the parameter for all participating
laboratories. Locally named reference materials are fuel samples analyzed using the reference
test method, either at your laboratory or at a reference installation, to establish an estimated value
for the fuel parameter; locally named reference materials usually come from the fuel you
produce.
(3)	You may qualify your procedure as meeting the variability requirements of paragraph
(f)(1) of this section only for a narrower, defined range of fuels. If this is the case, identify the
appropriate range of fuels in your request for approval and describe how you will screen fuel
samples accordingly.
(4)	Qualify the precision of the alternative procedure by comparing results to testing with
the referee procedure based on "between methods reproducibility," Rxy, as specified in ASTM
D6708. The Rxy must be at or below 75 percent of the reproducibility of the referee procedure
from §1090.1360(d).
(5)	Perform testing at your laboratory as specified in paragraph (b) of this section to
establish the repeatability of the alternative procedure. The repeatability must be as good as or
better than that specified in paragraph (b)(3) of this section.
(6)	Fully describe the procedure to show how it functions for achieving accurate
measurements. Describe the technology, test instruments, and testing method so a competent
person lacking experience with the procedure and test instruments would be able to replicate the
results.
(7)	Engage a third-party auditor to review and verify your information as follows:
(i) The auditor must qualify as an independent third party and meet the specifications for
technical ability as specified in §1090.55.
Page 143 of 190

-------
(ii)	The auditor must send you a report describing its inspection of your facilities and its
review of the information supporting your request to use the alternative procedure. The report
must describe how the auditor performed the review, identify any errors or discrepancies, and
state whether the information supports a conclusion that the alternative procedure should be
approved.
(iii)	The auditor must keep records related to the review for at least 5 years after sending
you the report and upon request, provide those records for EPA review.
(8) Send EPA a written request to use the alternative procedure. Include the specified
information and any additional information we need to evaluate your request. We will approve
your request for a specific laboratory if you meet the specified requirements. We will make best
efforts to notify you of our decision within 90 days. We will describe our reasons if we
disapprove your request.
(g)	We may find from testing that an alternative procedure qualifying under this section
in fact does not meet performance specifications. If this happens, we will notify you in writing
how to deal with invalid test results and describe what you need to do to be able to use the
alternative procedure.
(h)	Keep fuel samples from any qualification testing under this section for at least 180
days after you have taken all steps to qualify an alternative procedure under this section. This
applies for testing at your laboratory and at any reference installation you use for demonstrating
the accuracy of an alternative procedure.
§1090.1370 Qualifying criteria for reference installations.
(a)	A reference installation refers to a test facility that uses the referee test method
specified in §1090.1360(d) to evaluate the accuracy of alternative procedures for method-defined
parameters, by comparing measured values to companion tests using one of the referee
procedures in §1090.1360(d). This evaluation may result in an equation to correlate results
between the two procedures. Once a facility qualifies as a reference installation, that
qualification is valid for five years from the qualifying date, consistent with good laboratory
practices.
(b)	Qualify a reference installation for VCSB procedures by participating in an
interlaboratory crosscheck program with at least 16 separate measurements that are not identified
as outliers. This presumes that the results for the candidate reference installation are not outliers.
(c)	Qualify a reference installation for non-VCSB procedures based on the following
measurement protocol:
(1) Use the precision testing procedure specified in §1090.1365(b) to show that your
standard deviation for tests using the reference test method is at or below 0.3 times the
reproducibility for a given fuel parameter.
Page 144 of 190

-------
(2)	You must correlate your test results for a given fuel parameter against the accepted
reference values from a monthly crosscheck program based on Section 6.2.2.1 and Note 7 of
ASTM D6299 (incorporated by reference in §1090.95) as follows:
(i)	If there are multiple fuels available from the crosscheck program, select the fuel that
has the closest value to the standard. If there is no standard for a given fuel parameter, select the
fuel with values for the fuel parameter that best represent typical values for fuels you test.
(ii)	Measure the fuel parameter for the crosscheck fuel at your facility using the
appropriate referee procedure. Calculate a mean value that includes all your repeat
measurements.
(iii)	Determine the mean value from the crosscheck program and calculate the difference
between this value and the mean value from your testing. Express this difference as a certain
number of standard deviations relative to the data set from the crosscheck program.
(iv)	The calculated monthly difference between the mean values from paragraph (b)(2)(ii)
of this section for 5 consecutive months must fall within the central 50 percent of the distribution
of data at least 3 times. The central 50 percent of the distribution corresponds to 0.68 standard
deviations.
(v)	Calculate the mean value of the differences from paragraph (b)(2)(ii) of this section
for all 5 months. This mean value must fall within the central 50 percent of the distribution of
data from the crosscheck program. For example, if the difference was 0.5 standard deviations for
two months, 0.6 for one month, and 0.7 for two months, the mean value of the difference is 0.6
standards deviations, and the reference installation meets the requirements of this paragraph.
(3)	You must demonstrate that the reference installation is in statistical quality control for
at least 5 months with the designated procedure as specified in ASTM D6299 (incorporated by
reference in §1090.95). If at any point the reference installation is not in statistical quality
control, you must make any necessary changes and restart testing toward meeting the
requirement to achieve statistical quality control for at least 5 months, except as follows:
(i)	Do not consider measurements you perform as part of regular maintenance or
recalibration for evaluating statistical quality control.
(ii)	If you find that the reference installation is not in statistical quality control during an
initial 5-month period and you are able to identify the problem and make the necessary changes
to again achieve statistical quality control before the end of the 5-month demonstration period,
you may consider the reference installation as meeting the requirement to be in statistical quality
control for at least 5 months.
§1090.1375 Quality control procedures.
This section specifies ongoing quality testing requirements as part of the Performance-
based Measurement System specified in §1090.1360.
Page 145 of 190

-------
(a)	General provisions. You must perform testing to show that your test facility meets
specified precision and accuracy criteria as follows:
(1)	The testing requirement applies for the referee procedures in §1090.1360(d) and for
alternate procedures that are qualified or approved under §1090.1365. The testing requirements
apply separately for each test instrument at each test facility.
(2)	If you fail to conduct specified testing, your test facility is not qualified for measuring
fuel parameters to demonstrate compliance with the standards and other specifications of this
part until you perform this testing. Similarly, if your test facility fails to meet the specified
criteria, it is not qualified for measuring fuel parameters to demonstrate compliance with the
standards and other specifications of this part until you make the necessary changes to your test
facility and perform testing to show that the test facility again meets the specified criteria.
(3)	If you perform major maintenance such as overhauling an instrument or recalibrating
it, confirm that the instrument still meets precision and accuracy criteria before you start testing
again. Use the Q-procedure with the MR chart in ASTM D6299 (incorporated by reference in
§1090.95).
(4)	Keep records to document your testing under this section for 5 years.
(b)	Precision demonstration. Show that you meet precision criteria as follows:
(1)	Meeting the precision criteria qualifies your test facility for performing up to 20
production tests or 7 days, whichever is less.
(2)	Perform precision testing using the control-chart procedures in ASTM D6299
(incorporated by reference in §1090.95). If you opt to use the Q-procedure, validate the first run
on the new QC batch by either an overlap in-control result of the old batch, or by a single
execution of an accompanying standard reference material. The new QC material result would be
considered validated if the single result of the standard reference material is within the
established site precision (R') of the ARV of the standard reference material, as determined by
ASTM D6792.
(3)	Use I charts and MR charts as specified in ASTM D6299 to show that the long-term
standard deviation for the test facility meets the precision criteria specified in §1090.1365(b).
(c)	Accuracy demonstration. For absolute fuel parameters (VCSB and non-VCSB) and
for method-defined fuel parameters using non-VCSB methods, you must show that you meet
accuracy criteria as specified in this paragraph. For method-defined VCSB procedures, you may
meet accuracy requirements as specified in this paragraph or by comparing your results to the
accepted reference value in an inter-laboratory crosscheck program sponsored by ASTM
International or another voluntary consensus standards body at least 3 times per year.
(1)	Meeting the accuracy criteria qualifies your test facility for 130 days.
(2)	Except as specified in paragraph (c)(3) of this section, test every instrument using a
check standard meeting the specifications of ASTM D6299 (incorporated by reference in
Page 146 of 190

-------
§1090.95). Select a fuel sample with an ARV that is at or slightly below the standard that
applies. If there are both average and batch standards, use the average standard. If there is no
standard, select a fuel sample representing fuel that is typical for your testing.
(3)	The following provisions apply for method-defined non-VCSB alternative procedures
with high sensitivity to sample-specific bias:
(i)	Procedures have high sensitivity if the closeness sum of squares (CSS) statistic
exceeds the 95th percentile value, as specified in ASTM D6708 (incorporated by reference in
§1090.95).
(ii)	Create a check standard from production fuel representing the fuel you will routinely
analyze. Determine the ARV of your check standard using the protocol in ASTM D6299 at a
reference installation as specified in §1090.1370.
(iii)	You must send EPA a fuel sample from every twentieth batch of gasoline or diesel
fuel and identify the procedures and corresponding test results from your testing. We may return
one of your samples to you for further testing; if we do this, you must repeat your measurement
and report your results within 180 days of receiving the fuel sample.
(4)	You meet accuracy requirements under this section if the difference between your
measured value for the check standard and the ARV is less than the value from the following
equation: Amax
Where,
R = the reproducibility of the referee procedure identified in §1090.1360(d), as noted in
Table 1 to §1090.1365 or in the following table:

1090.1380 Requirement for Automated Detergent Blending Equipment Calibration.
(a)	Automated detergent blending facilities must calibrate their automated detergent
blending equipment once in each calendar half-year, with the acceptable calibrations being no
less than 120 days apart.
(b)(1)	Equipment recalibration is also required each time the detergent package is
changed, unless written documentation indicates that the new detergent package has the same
viscosity as the previous detergent package.
(2) Detergent package change calibrations may be used to satisfy the semiannual
requirement in paragraph (a) of this section, provided that the calibrations occur in the
appropriate calendar half-year and are no less than 120 days apart.
GASOLINE DEPOSIT CONTROL TESTING
§1090.1395 Gasoline deposit control test procedures.
Gasoline detergent manufacturers must perform testing as specified in paragraph (a), (b),
or (c) of this section to certify detergents and establish the lowest additive concentration (LAC)
for the detergent.
(a) Top Tier-Based Test Method. Gasoline detergent manufacturers may perform testing
to certify the detergent and establish the LAC for the detergent using the procedures specified in
ASTM D6201 (incorporated by reference in §1090.95), as follows:
(1) Use a base fuel that conforms to the specifications for gasoline-alcohol blends in
ASTM D4814 (incorporated by reference in §1090.95). Blendstocks used to formulate the test
fuel must be derived from conversion units downstream of distillation, with all processes
representing normal fuel manufacturing facility operations. Blendstocks may not come from
chemical grade streams. Butane and pentane may be added to adjust vapor pressure. The base
fuel should include any nondetergent additives typical of commercially available fuel if they may
positively or negatively affect deposit formation. In addition, the base fuel must have-
(i)	8.0-10.0 volume percent DFE that meets the requirements in §1090.230 and conforms
to the specifications of ASTM D4806 (incorporated by reference in §1090.95).
(ii)	At least 8.0 volume percent olefins.
(iii)	At least 15 volume percent aromatics.
(iv)	No more than 80 ppm sulfur.
(v)	T90 distillation temperature at or above 143 °C.
(vi)	No detergent-active substance. A base fuel with typical nondetergent additives, such
as antioxidants, corrosion inhibitors, and metal deactivators, may be used.
Page 148 of 190

-------
(2)	Perform the 100-hour test for intake valve deposits with the base fuel to demonstrate
that the intake valves accumulate at least 500 mg on average. If the test engine fails to
accumulate enough deposits, make any necessary adjustments and repeat the test. This
demonstration is valid for any further detergent testing with the same base fuel.
(3)	Repeat the test on the same engine with a specific concentration of detergent added to
the base fuel. If the test results in less than 50 mg average per intake valve., the tested detergent
concentration is the LAC for the detergent.
(b)	CARB-Based Test Method. Gasoline detergent manufacturers may perform testing to
certify the detergent and establish the LAC for a detergent using the procedures specified by
CARB in Title 13, California Code of Regulations, section 2257.
(1)	A detergent certified under this option may be used at the LAC specified for use in
the state of California in any gasoline in the United States.
(2)	A certification under this option will continue to be valid only as long as the CARB
certification remains valid. The gasoline detergent manufacturer must cease selling a detergent
immediately upon being notified by CARB that the CARB certification for this detergent has
been invalidated and must notify EPA under 40 CFR 79.21.
(c)	Alternative test methods. (1) Gasoline detergent manufacturers may use an EPA-
approved alternative test method to certify a detergent and establish the LAC for a detergent if
the alternative test method can be correlated to any one of the following methods.
(1)	The Top Tier-Based Test Method specified in paragraph (a) of this section.
(ii)	The CARB-Based Test Method in paragraph (b) of this section.
(iii)	The retired EPA BMW Test Method as follows:
(A) Prepare the test fuel with the following specification:
(/) Sulfur - minimum 340 ppm.
(2)	T-90 - minimum 339 degrees Fahrenheit.
(3)	Olefins - minimum 11.4 volume percent.
(4)	Aromatics - minimum 31.1 volume percent.
(5)	Ethanol - minimum 10 volume percent.
(6)	Sulfur, T-90, olefins, and aromatics specifications must be met prior to the addition of
ethanol.
(7)	Di-tert-butyl disulfide may be added to the test fuel to help meet the sulfur
specification.
Page 149 of 190

-------
(B) Using the test fuel meeting the requirements of paragraphs (c)(l)(iii)(A) of this
section, test the test fuel with and without detergent in accordance with ASTM D5500
(incorporated by reference in §1090.95) and under the following conditions:
(/) The unadditized fuel's test results must meet or exceed 290 mg per valve on average.
(2)	The required test fuel, including detergent additives, must produce the accumulation
of less than 100 mg of intake valve deposits on average.
(3)	The duration of the demonstration tests under ASTM D5500 may be less than the
specified 10,000 miles, provided the results satisfy the standards of this paragraph.
(4)	If the demonstration test results do not meet these criteria, then the formulated fuel
may not be used for detergent certification testing.
(2)	Alternative test methods for the certification of detergent additives must be correlated
to one of the methods described in paragraph (c)(1) of this section a method described in the
submission.
(3)	Information describing the alternative test method and analysis demonstrating
correlation must be submitted for EPA approval as specified in §1090.10.

(2)	One survey during the period of April 1 through June 30.
(3)	One survey during the period of July 1 through September 30.
(4)	One survey during the period of October 1 through December 31.
(b)	Sampling areas. The survey program plan must include sampling in all sampling
strata, as defined in §1090.80, during each survey. These sampling strata must be further divided
into discrete sampling areas or clusters. Each survey must include sampling in at least 40
sampling areas in each stratum that are randomly selected.
(c)	No advance notice of surveys. The survey plan must include procedures to keep the
identification of the sampling areas that are included in any survey program plan confidential
from any party participating in the survey program specified in §1090.1400 prior to the
beginning of a survey in an area. However, this information must not be kept confidential from
EPA.
(d)	Gasoline and diesel retail outlet selection. (1) Gasoline and diesel retail outlets to be
sampled in a sampling area must be selected from among all gasoline retail outlets in the United
States that sell gasoline with the probability of selection proportionate to the volume of gasoline
sold at the retail outlet. The sample of retail outlets must also include gasoline retail outlets with
different brand names as well as those gasoline retail outlets that are unbranded.
(2)	For any gasoline or diesel retail outlet from which a sample of gasoline was collected
during a survey was reported to EPA under §1090.1410(e), that gasoline or diesel retail outlet
must be included in the subsequent survey.
(3)	At least one sample of a product dispensed as El 5 must be collected at each gasoline
retail outlet when El5 is present, and separate samples must be taken that represent the gasoline
contained in each storage tank at the gasoline retail outlet unless collection of separate samples is
not practicable.
(4)	At least one sample of a product dispensed as diesel fuel must be collected at each
diesel fuel retail outlet when diesel fuel is present. Samples of diesel fuel may be collected at
retail outlets that sell gasoline.
(e)	Number of samples. (1) The number of retail outlets to be sampled must be
independently calculated for the total number of gasoline retail outlets and the total number of
Page 153 of 190

-------
diesel fuel retail outlets. The same retail outlet may represent both a gasoline retail outlet and a
diesel fuel retail outlet for purposes of determining the number of samples.
(2) The minimum number of samples to be included in the survey plan for each calendar
year is calculated as follows:
n = Minimum number of samples in a year-long survey series. However, n must be
greater than or equal to 2,000 for the number of diesel samples or 5,000 for the number of
gasoline samples.
Za = Upper percentile point from the normal distribution to achieve a one-tailed 95%
confidence level (5% a-level). Thus, Za equals 1.645.
Zp = Upper percentile point to achieve 95% power. For purposes of this survey program,
Zp equals 1.645.
(pi = The maximum proportion of non-compliant outlets for a region to be deemed
compliant. In this test, the parameter needs to be 5% or greater, i.e., 5% or more of the outlets,
within a stratum such that the region is considered non-compliant. For this survey, (pi will be 5%.
(po = The underlying proportion of non-compliant outlets in a sample. For the first survey
plan, (po will be 2.3%. For subsequent survey plans, (po will be the average of the proportion of
outlets found to be non-compliant over the previous 4 surveys.
Fa = Adjustment factor for the number of extra samples required to compensate for
collected samples that cannot be included in the survey, based on the number of additional
samples required during the previous 4 surveys. Fa must be greater than or equal to 1.1.
Fb = Adjustment factor for the number of samples required to resample each retail outlet
with test results reported to EPA under §1090.1410(e), based on the rate of resampling required
during the previous 4 surveys. Fb must be greater than or equal to 1.1.
Sun = Number of surveys per year. For purposes of this survey program, Sun equals 4.
Stn = Number of sampling strata. For purposes of this survey program, Stn equals 3.
(3) The number of gasoline samples that also need to be tested for aromatics, olefins, and
distillation parameters under §1090.1410(c)(2) must be calculated using the methodology
specified in paragraph (e)(2) of this section without the Fa, Fb, and Sun parameters.

Subpart P—Importation and Exportation of Fuels, Fuel Additives, and Regulated
Blendstocks
§1090.1600 General provisions for importers.
(a)	This subpart specifies certain provisions that apply to any person who imports fuels,
fuel additives, or regulated blendstocks.
(b)	The party that is the importer of record for U.S. Customs Service is the importer for
purposes of this part.
(c)	For importers that import fuel at multiple import facilities in the same PADD, the
facilities must be aggregated together for purposes of complying with average standards and
reporting as an aggregated import facility.
(d)	Importers must separately comply with any applicable certification or other
requirements for U.S. Customs.
(e)	Alternative testing requirements for importing gasoline or diesel fuel by rail or truck
are specified in §1090.1620.
§1090.1605 Importation by marine vessel.
(a)	Importers that import fuels using a marine vessel must certify gasoline, diesel fuel,
ECA marine fuel, oxygenates, certified ethanol denaturant, certified butane, and certified pentane
imported at each port, even if these products are transported by the same vessel making multiple
stops.
(b)(1)	Except as specified in paragraph (d) of this section, importers of gasoline, diesel
fuel, ECA marine fuel, oxygenates, certified ethanol denaturant, certified butane, and certified
pentane by marine vessel must certify the product while it is on board the vessel used to transport
it to the United States, while certification sampling must be performed after the vessel's arrival at
the port where the product will be offloaded.
(2)	Importers must sample each compartment of the vessel and treat each ship
compartment as a separate batch unless the importer collects samples from different ship
compartments into a single, volume-weight composite sample using ASTM D4057 and
demonstrates that the gasoline or diesel fuel is homogeneous across the compartments under
§1090.1337.
(3)	Importers must assure that all gasoline, diesel, oxygenates, and pentane meet all
applicable per-gallon standards before offloading the product.
(4)	Importers may not rely on testing conducted by a foreign supplier.
(c)	Once gasoline, diesel fuel, ECA marine fuel, oxygenates, certified ethanol denaturant,
certified butane, and certified pentane on a vessel have been certified under paragraph (b) of this
section, the product may be transferred to shore tanks using smaller vessels or barges (lightered)
Page 166 of 190

-------
as a certified product. These lightering transfers may be to terminals located in any harbor and
are not restricted to terminals located in the harbor where the ship is anchored. For example,
certified gasoline could be transferred from a ship anchored in New York harbor to a lightering
vessel and transported to Albany, New York or Providence, Rhode Island without separately
certifying the gasoline upon arrival in Albany or Providence. In this lightering situation, transfers
to a lightering vessel must meet the PTD requirements.
(d) As an alternative to paragraphs (b) and (c) of this section, importers may offload
gasoline into shore tanks containing gasoline, diesel into shore tanks containing diesel fuel,
oxygenates into shore tanks containing oxygenates, and certified pentane into shore tanks
containing certified pentane if the importer meets the following requirements:
(1) For gasoline, importers must offload gasoline into one or more empty shore tanks or
tanks containing PCG that the importer owns.
(1)	If importers offload gasoline into one or more empty shore tanks, they must sample
and test the sulfur and benzene content, and RVP for summer gasoline, of each shore tank into
which product was offloaded.
(ii) If importers offload gasoline into one or more shore tanks containing PCG, they must
sample the PCG already in the shore tank prior to offloading gasoline from the marine vessel,
test the sulfur and benzene content, and report this product as a batch with a negative volume.
After offloading the gasoline into the shore tanks, the importer must sample and test the sulfur
and benzene content, and RVP for summer gasoline, of each shore tank into which product was
offloaded and report the volume and sulfur and benzene content as a positive batch.
(2)	For diesel fuel, oxygenates, and certified pentane, importers must sample and test the
product in each shore tank into which product was offloaded. Importers must assure that all these
products meet all applicable per-gallon standards before introduction into commerce.
§1090.1610 General provisions for exporters.
Except as specified in this section and in subpart G of this part, gasoline and diesel fuel
produced, imported, distributed, or offered for sale in the United States is subject to the standards
and requirements of this part.
(a)	Fuels designated for export by a fuel manufacturer are not subject to the standards in
this part, provided they are ultimately exported to a foreign country. However, such fuels must
be designated at the fuel manufacturing facility and must be accompanied by documentation
stating for "export only" that complies with the PTD requirements of subpart K of this part.
Refiners must retain records to demonstrate that the fuel was exported. Fuel designated for
export must be segregated from all fuel intended for use in the United States.
(b)	Fuel not designated for export may be exported without restriction. However, the fuel
remains subject to the provisions of this part while in the United States. For example, fuel
designated as ULSD must meet the applicable sulfur standards even if it will later be exported.

States and has not been mixed with gasoline produced at a fuel manufacturing facility located
outside the United States.
(2)	Such fuel must be included in compliance calculations by the producing gasoline
manufacturer.
(3)	All the fuel that was exported must ultimately be classified as American Goods
Returned to the U.S. and none may be used in a foreign country.
(4)	No fuel classified as American Goods Returned to the U.S. may be combined with
any fuel produced at a foreign fuel manufacturing facility prior to importation into the United
States.
§1090.1615 Gasoline treated as a blendstock.
(a)	Importers may exclude GTAB from their compliance calculations if they meet the
following criteria:
(1)	The importer reports such GTAB to EPA under §1090.905(c)(7).
(2)	Such GTAB is treated as blendstock at a related fuel manufacturing facility that
produces gasoline using the GTAB.
(3)	The related fuel manufacturing facility must report the gasoline produced using such
GTAB and must include the gasoline produced using such GTAB in its compliance calculations.
(b)	After importation, the title of the GTAB may not be transferred to another party until
the GTAB has been blended to produce gasoline and all applicable standards and requirements
have been met for the gasoline produced.
(c)	The facility at which the GTAB is used to produce gasoline must be physically
located at either the same terminal at which the GTAB first arrives in the United States, the
import facility, or at a facility to which the GTAB is directly transported from the import facility.
(d)(1)	The importer must complete all requirements for gasoline importers under
§1090.105(a) except for the sampling, testing, and sample retention requirements in
§1090.105(a)(5) for the GTAB at the time it is imported as if the GTAB were imported gasoline.
(2) Any GTAB that ultimately is not used to produce gasoline (e.g., a tank bottom of
GTAB) must be treated as newly imported gasoline and must meet all applicable requirements
for imported gasoline.

manufacturer, but engaged for transportation of fuels, fuel additives, or regulated blendstocks
despite specifications or inspections of procedures and equipment that are reasonably calculated
to prevent such action.
(c)	Under paragraph (a) of this section, for any person to show that a violation was not
caused by that person, or under paragraph (b) of this section to show that a violation was caused
by any of the specified actions, the person must demonstrate by reasonably specific showings,
through direct or circumstantial evidence, that the violation was caused or must have been
caused by another person and that the person asserting the defense did not contribute to that other
person's causation.
(d)	To demonstrate an acceptable quality assurance program under paragraph (a)(3) of
this section, a person must present evidence of all the following:
(1)	A periodic sampling and testing program adequately designed to ensure the fuel, fuel
additive, or regulated blendstock the person sold, dispensed, supplied, stored, or transported
meets the applicable per-gallon standard. A person may meet this requirement by participating in
a survey program that was in effect at the time of the violation that meets the requirements in
subpart N of this part. In addition to participation in a survey program under subpart N of this
part, gasoline manufacturers must also participate in the national sampling oversight program
specified in §1090.1440 at the time of the violation.

received in the ordinary course of business concerning gasoline quality and delivery.
(e) In addition to the defenses provided in paragraphs (a) through (d) of this section, in any
case in which an ethanol blender, distributor, reseller, carrier, retailer, or wholesale purchaser-
consumer would be in violation under §1090.1715 as a result of gasoline that contains between 9
and 15 percent ethanol (by volume) but exceeds the applicable standard by more than 1.0 psi, the
ethanol blender, distributor, reseller, carrier, retailer or wholesale purchaser-consumer will not be
deemed in violation if such person can demonstrate, by showing receipt of a certification from
Page 173 of 190

-------
the facility from which the gasoline was received or other evidence acceptable to EPA, all of the
following:
(1)	The gasoline portion of the blend complies with the applicable RVP standard in
§1090.215.
(2)	The ethanol portion of the blend does not exceed 15 percent (by volume).
(3)	No additional alcohol or other additive has been added to increase the RVP of the
ethanol portion of the blend.
(4)	In the case of a violation alleged against an ethanol blender, distributor, reseller, or
carrier, if the demonstration required by paragraphs (e)(1), (2), and (3) of this section is made by
a certification, it must be supported by evidence that the criteria in paragraphs (e)(1), (2), and (3)
of this section have been met, such as an oversight program conducted by or on behalf of the
ethanol blender, distributor, reseller or carrier alleged to be in violation, which includes periodic
sampling and testing of the gasoline or monitoring the volatility and ethanol content of the
gasoline. Such certification will be deemed sufficient evidence of compliance provided it is not
contradicted by specific evidence, such as testing results, and provided that the party has no other
reasonable basis to believe that the facts stated in the certification are inaccurate. In the case of a
violation alleged against a retail outlet or wholesale purchaser-consumer facility, such
certification will be deemed an adequate defense for the retailer or wholesale purchaser-
consumer, provided that the retailer or wholesale purchaser-consumer is able to show certificates
for all of the gasoline contained in the storage tank found in violation, and, provided that the
retailer or wholesale purchaser-consumer has no reasonable basis to believe that the facts stated
in the certifications are inaccurate.
