§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.
      (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.

Any negative compliance sulfur or benzene value must be reported as zero and not as a negative result.
      (ii) For PCG by addition as specified in §1090.1320(a)(2), include only the blendstock added to make the new batch of gasoline as a batch with a positive volume and positive sulfur and benzene content of in compliance calculations under this section. Do not include any test results or volumes for the PCG or new batch of gasoline in these calculations.
      (5) Inclusion of a particular batch of gasoline for compliance calculations for a compliance period is based on the date the batch is produced, not shipped. For example, a batch produced on December 30, 2021, but shipped on January 2, 2022, would be included in the compliance calculations for the 2021 compliance period. However, the volume included in the 2021 compliance period for that batch would be the entire batch volume, even though the shipment of all or some of the batch did not occur until 2022.
      (e) Exclusions. Gasoline manufacturers must exclude the following products from their compliance calculations:
      (1) Gasoline that was not produced by the gasoline manufacturer.

      (d) The credit has not been transferred between EPA registered companies more than twice. The first transfer by the gasoline manufacturer that generated the credit ("transferor") may only be made to a gasoline manufacturer that intends to use the credit ("transferee"). If the transferee is unable to use the credit, it may make the second, and final, transfer only to a gasoline manufacturer that intends to use the credit. Intracompany credit transfers are unlimited.
      (e) The transferor must apply any credits necessary to meet the transferor's applicable average standard before transferring credits to any other gasoline manufacturer.
      (f) No person may transfer credits if the transfer would cause them to incur a deficit.
      (g) Unless the transferor and transferee are the same party (i.e., intracompany transfers), the transferor must supply to the transferee records as specified in §1090.1210(g) indicating the years the credits were generated, the identity of the gasoline manufacturer that generated the credits, and the identity of the transferring party.

      For credits that have been calculated or generated improperly, or are otherwise determined to be invalid, all the following provisions apply:
      (a) Invalid credits may not be used to achieve compliance with an average standard, regardless of the good faith belief that the credits were validly generated.
      (b) Any validly generated credits existing in the transferring gasoline manufacturer's credit balance after correcting the credit balance, and after the transferor applies credits as needed to meet the average standard at the end of the compliance period, must first be applied to correct the invalid transfers before the transferring gasoline manufacturer trades or banks the credits.
      (c) The gasoline manufacturer that used the credits, and any transferor of the credits, must adjust their credit records, reports, and average standard compliance calculations as necessary to reflect the use of valid credits only. Updates to any reports must be done in accordance with subpart J of this part using forms and procedures specified by EPA.

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.
      (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 (VCSB) 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.

Also, 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. Follow the procedures in paragraph (b) of this section for manual sampling. Follow the procedures paragraph (c) of this section for automatic sampling. Additional requirements for measuring RVP are specified in paragraph (d) 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 spot sampling for partially filled tanks as shown in Table 1 or Table 5 of ASTM D4057 as applicable. For tap sampling, collect samples that most closely match the recommendations in Table 5 of ASTM D4057. If you test more than one sample for a given fuel parameter, calculate the arithmetic average of the test results to represent the batch and use the average result for determining compliance with the standards under this part. Each measured sample must meet all applicable per-gallon standards. If you test only one sample for a given parameter, you must use that test result to represent the batch. You may not use the results from a composite sample to determine compliance with the standards under this part.
      (2) Collect a "running" or "all-levels" sample from the top of the tank. 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 procedures 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 primarily 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, except that the homogeneity testing requirement does not apply in the following cases:
      (i) There is only a single sample using the procedures specified in paragraph (b)(1) of this section.
      (ii) Upright cylindrical tanks that have a liquid depth (from the tank outlet) less than 10 feet.
      (iii) You draw spot or tap samples as specified in paragraph (b)(1) of this section and test each sample for every parameter subject to a testing requirement and use the worst-case test result for each parameter for purposes of reporting, meeting per-gallon and average standards, and all other aspects of compliance.
      (iv) Sampling at a downstream location where it is not possible to collect separate samples and you take steps to ensure that the batch is well mixed.
      (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. The default sampling frequency should follow the recommended approach of at least 9,604 samples to represent a batch. EPA may approve a less frequent sampling strategy under §1090.1315(b)(2) if it is appropriate for a given facility or for a small-volume batch. 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:
      (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 applicable RVP standard.
      (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 levels of stored fuel, fuel additive, or regulated blendstock in the tank as specified in §1090.1335(b)(1).
      (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 the sulfur content of each sample as specified in this subpart.
      (3) Measure the benzene content of each sample as specified in this subpart.
      (4) Measure the RVP of 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 one of the procedures specified in paragraph (c)(1) or (2) of this section.
      (e) Consider the 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 all meaningful significant figures as specified for the test method, even if §1090.1350(c) describes a different precision. For cases that do not require a homogeneity demonstration under §1090.1335(b)(4), the lack of homogeneity demonstration does not prevent a quantity of fuel, fuel additive, or regulated blendstock from being considered a batch for demonstrating compliance with the requirements of this part.
§1090.1340 Preparing a hand blend 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 oxygenate to the BOB sample in a way that corresponds to your instructions to downstream blenders for the sampled batch of fuel. Prepare a hand blend representing a worst case for oxygenate 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 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, E15, 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 does not exceed the oxygenate concentration specified on the PTD for the BOB under §1090.1160(b)(1).
      (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 oxygenate tested under this subpart as follows:
      (1) If you test gasoline, diesel fuel, or oxygenate to measure any parameter 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 produce 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 blend, select a representative sample as follows:
      (i) If you test a hand blend under §1090.1340, keep a sample of the BOB.
      (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.
      (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 records of all calculations, test results, and test methods for the batch associated with each stored sample.
      (d) If EPA requests a test sample, you must follow EPA's instructions and send it to EPA by a courier service (or equivalent). The instructions will describe where and when to send the sample. For each test sample, you must identify the test results and test methods used.
      (e) You are responsible for meeting the 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) Except as specified in paragraph (b) of this section, 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:
      (1) Sulfur content of diesel fuel.
      (2) Sulfur content of ECA marine fuel.
      (3) RVP, sulfur content, benzene content, 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 content of 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.
      (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 the benzene content of butane and pentane as specified in ASTM D5134 (incorporated by reference in §1090.95).
      (5) Measure the sulfur content of 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) 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.
      (12) Updated versions of the test procedures specified in this section are acceptable as alternative procedures if both repeatability and reproducibility are at least as precise as the values specified in the earlier version.
      (c) Record measured values with the following precision, with rounding in accordance with §1090.50:
      (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 measurement or calculation that depends 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 as follows:
      RVP (psi) = 0.956 ∙ Ptotal − 0.347
      Where:
      Ptotal = Measured total vapor pressure, in psi.
      (b) For measuring the sulfur and benzene content of 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.
      (c) For measuring the benzene content of butane and pentane, report a zero value if the test result is at or below the PLOQ or Limit of Detection (LOD) 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 (PBMS) 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.
      (1) Absolute fuel parameters are those 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. The following are absolute fuel parameters:
      (i) Sulfur. This applies for measuring sulfur in any fuel, fuel additive, or regulated blendstock.
      (ii) [Reserved]
      (2) 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 advance approval by EPA. 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.
      (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) 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 required in this part.
      (ii) Qualification testing is not required for laboratories that measure the benzene content of 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:
      Table 1 to paragraph (d)

§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:
      (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 PLOQ and no specified scope with a lower bound, you must establish a LLOQ 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 paragraph (b)(3) of 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 as follows:
      σmax=x1∙x2x3
      Where:
      σmax = Maximum allowable standard deviation.
      x1, x2, and x3 have the values from the following table:

[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 gravimetric sulfur standards 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 the sulfur content of 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, gasoline regulated blendstock, and gasoline additive 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 as follows:
      ∆max=0.75∙σmax
      Where:
      Δmax = Maximum allowable difference.
      σmax = 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 paragraph (c)(3)(ii) of 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. 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.
      (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.
      (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.
      (ii) The auditor must send you a report describing their inspection of your facilities and their 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 provide those records to EPA upon request.
      (8) Send EPA a written request to use the alternative procedure. Include the specified information and any additional information EPA needs to evaluate your request.
      (g) 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.
      (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 §1090.1365(c)(3)(ii) 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 §1090.1365(c)(3)(ii) 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.
      (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, confirm that the instrument still meets precision and accuracy criteria before you start testing again based on the procedures specified 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 of this paragraph (b) 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. 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 (incorporated by reference in §1090.95).
      (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 VCSB at least 3 times per year.
      (1) Meeting the accuracy criteria of this paragraph (c) 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. 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 95[th] 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. EPA may return one of your samples to you for further testing; if this occurs, 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:
      Δmax=0.75∙R∙1+1L
      Where:
      Δmax = Maximum allowable difference.
      R = Reproducibility of the referee procedure identified in §1090.1360(d), as noted in Table 1 to paragraph (b)(3) of §1090.1365 or in the following table:
      Table 1 to paragraph (c)(3)

TESTING RELATED TO GASOLINE DEPOSIT CONTROL
§1090.1390 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) 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. Calibrating after changing the detergent package may be used to satisfy the semiannual recalibration 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.
§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 establish the lowest additive concentration (LAC) for the detergent.
      (a) Top Tier-Based Test Method. Use 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 the following properties:
      (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.
      (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. Use the procedures specified by CARB in Title 13, California Code of Regulations, section 2257.
      (1) A detergent tested under this option or certified under 40 CFR 80.163(d) prior to January 21, 2021, may be used at the LAC specified for use in the state of California in any gasoline in the United States.
      (2) 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) An EPA-approved alternative test method may be used if the alternative test method can be correlated to any one of the following methods.
      (i) 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:
      (1) 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.
      (B) Using the test fuel meeting the requirements of paragraphs (c)(1)(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:
      (1) 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.
      (C) If the demonstration test results do not meet the criteria in paragraph (c)(1)(iii)(B) of this section, then the formulated fuel may not be used for detergent deposit control testing.
      (2) Alternative test methods for detergent additives must be correlated to one of the methods specified in paragraph (c)(1) of this section 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.

§1090.1415 Survey plan design requirements.
      The national fuels survey program plan must include all the following:
      (a) Number of surveys. The survey program plan must include 4 surveys each calendar year that occur during the following time periods:
      (1) One survey during the period of January 1 through March 31.
      (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 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 program plan must include procedures to keep the identification of the sampling areas that are included in the plan confidential from any participating party 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 or diesel 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 E15 must be collected at each gasoline retail outlet when E15 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 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=Zα+Zβ24∙arcsinφ1-arcsinφ02∙Fa∙Fb∙Sun∙Stn
      Where:
      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.
      Zα = Upper percentile point from the normal distribution to achieve a one-tailed 95% confidence level (5% α-level). For purposes of this survey program, Zα equals 1.645.
      Zβ = Upper percentile point to achieve 95% power. For purposes of this survey program, Zβ equals 1.645.
      φ1 = The maximum proportion of non-compliant outlets for a region to be deemed compliant. This 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).
      φ0 = The underlying proportion of non-compliant outlets in a sample. For the first survey plan, φ0 will be 2.3%. For subsequent survey plans, φ0 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 samples that could not be included in the survey (e.g., due to technical or logistical considerations), 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.
      (4) The number of samples determined under paragraphs (e)(2) and (3) of this section must be distributed approximately equally among the 4 surveys conducted during the calendar year.
      (f) Laboratory designation. Any laboratory that the independent surveyor intends to use to test samples collected as part of the national fuels survey program must be approved annually as part of the national fuels survey program plan approval process in §1090.1425. In the survey program plan submitted to EPA, the independent surveyor must include the following information regarding any laboratory they intend to use to test samples:
      (1) The name of the laboratory.
      (2) The address of the laboratory.
      (3) The test methods for each fuel parameter measured at the laboratory.
      (4) Reports demonstrating the laboratory's performance in a laboratory cross-check program for the most recent 12 months prior to submission of the plan.
      (g) Submission. Plans submitted under this section must be approved annually under §1090.1425.

      (a) E15 misfueling mitigation survey requirement. (1) Any gasoline manufacturer, oxygenate blender, or oxygenate producer that produces, introduces into commerce, sells, or offers for sale E15, gasoline, BOB, DFE, or gasoline-ethanol blended fuel that is intended for use in or as E15 must comply with either survey program Option 1 (as specified in paragraph (b) of this section) or Option 2 (as specified in paragraph (c) of this section).
      (2) For oxygenate producers that produce or import DFE, the DFE is deemed as intended for use in E15 unless an oxygenate producer demonstrates that it was not intended for such use. Oxygenate producers may demonstrate, at a minimum, that DFE is not intended for use in E15 by including language on PTDs stating that the DFE is not intended for use in E15, entering into contracts with oxygenate blenders to limit the use of their DFE to gasoline-ethanol blended fuels of no more than 10 volume percent, and limiting the concentration of their DFE to no more than 10 volume percent in their fuel additive registration under 40 CFR part 79.
      (b) Survey Option 1. To comply with the E15 misfueling mitigation survey requirement specified in paragraph (a) of this section, the gasoline manufacturer, oxygenate blender, or oxygenate producer must properly conduct a survey program in accordance with a survey program plan that has been approved by EPA in all areas that may be reasonably expected to be supplied with their gasoline, BOB, DFE, or gasoline-ethanol blended fuel. Such approval must be based on a survey program plan meeting all the following requirements:
      (1) The survey program must consist of at least quarterly surveys that occur during the following time periods in every year during which the gasoline manufacturer, oxygenate blender, or oxygenate producer introduces E15 into commerce:

      (a) This subpart contains provisions that apply to any person who imports fuel, fuel additive, or regulated blendstock.
      (b) Importers that import fuel at multiple import facilities must comply with the gasoline average standards as specified in §1090.705(b) unless the importer elects to comply with the alternative per-gallon standards for rail and truck imports specified in §§1090.205(d) and 1090.210(c).
      (c) Importers must separately comply with any applicable certification or other requirements for U.S. Customs.
      (d) Alternative testing requirements for importers that import gasoline or diesel fuel by rail or truck are specified in §1090.1610.
§1090.1605 Importation by marine vessel.
      Importers that import fuel, fuel additive, or regulated blendstock using a marine vessel must comply with the requirements of this section.
      (a) Importers must certify each fuel, fuel additive, or regulated blendstock imported at each port, even if it is transported by the same vessel making multiple stops.
      (b)(1) Except as specified in paragraph (d) of this section, importers must certify each fuel, fuel additive, or regulated blendstock while it is onboard the vessel used to transport it to the United States, and certification sampling must be performed after the vessel's arrival at the port where the fuel, fuel additive, or regulated blendstock will be offloaded.
      (2) Importers must sample each compartment of the vessel and treat each compartment as a separate batch unless the importer collects and combines samples from separate compartments into a single, volume-weight composite sample using ASTM D4057 (incorporated by reference in §1090.95) and demonstrates that the fuel, fuel additive, or regulated blendstock is homogeneous across the compartments under §1090.1337.
      (3) Importers must ensure that all applicable per-gallon standards are met before offloading the fuel, fuel additive, or regulated blendstock.
      (4) Importers must not rely on testing conducted by a foreign supplier.
      (c) Once the fuel, fuel additive, or regulated blendstock on a vessel has been certified under paragraph (b) of this section, it may be transferred to shore tanks using smaller vessels or barges (lightered) as a certified fuel, fuel additive, or regulated blendstock. These lightering transfers may be to terminals located in any harbor and are not restricted to terminals located in the harbor where the vessel is anchored. For example, certified gasoline could be transferred from an import vessel 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 scenario, transfers of certified gasoline to a lightering vessel must be accompanied by PTDs that meet the PTD requirements of subpart K of this part.
      (d) As an alternative to paragraphs (b) and (c) of this section, importers may offload fuel, fuel additive, or regulated blendstock into shore tanks containing the same fuel, fuel additive, or regulated blendstock 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.
      (i) If importers offload gasoline into one or more empty shore tanks, they must sample and test the sulfur and benzene content, and for summer gasoline, RVP, of each shore tank into which the gasoline 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 PCG 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 the gasoline was offloaded and report the volume and sulfur and benzene content as a positive batch.
      (2) For all other fuel, fuel additive, or regulated blendstock, importers must sample and test the fuel, fuel additive, or regulated blendstock in each shore tank into which it was offloaded. Importers must ensure that all applicable per-gallon standards are met before the fuel, fuel additive, or regulated blendstock is shipped from the shore tank.
§1090.1610 Importation by rail or truck.
      Importers that import fuel, fuel additive, or regulated blendstock by rail or truck may meet the sampling and testing requirements of subpart M of this part based on test results from the supplier if they meet all the following requirements:
      (a) The importer must get documentation of test results from the supplier for each batch of fuel, fuel additive, or regulated blendstock in accordance with the following requirements:
      (1) The testing must include measurements for all the fuel parameters specified in §1090.1310 using the measurement procedures specified in §1090.1350.
      (2) Testing for a given batch must occur after the most recent delivery into the supplier's storage tank and before transferring the fuel, fuel additive, or regulated blendstock to the railcar or truck.
      (b) The importer must conduct testing to verify test results from each supplier as follows:
      (1) Collect a sample at least once every 30 days or every 50 rail or truckloads from a given supplier, whichever is more frequent. Test such samples as specified in paragraphs (a)(1) and (2) of this section.
      (2) Treat importation of each fuel, fuel additive, or regulated blendstock separately, but treat railcars and truckloads together if the fuel, fuel additive, or regulated blendstock is imported from a given supplier by rail and truck.
      (c) If the importer fails to meet the requirements of paragraphs (a) and (b) of this section, they must perform testing as specified in §1090.1310 until EPA determines that the importer has adequately addressed the cause of the failure.
§1090.1615 Gasoline treated as a blendstock.
      (a) Importers may exclude GTAB from their compliance calculations if they meet all the following requirements:
      (1) The importer reports such GTAB to EPA under §1090.905(c)(7).
      (2) Such GTAB is treated as blendstock at a related gasoline manufacturing facility that produces gasoline using the GTAB.
      (3) The related gasoline manufacturing facility must report the gasoline produced using such GTAB and must include the gasoline produced using such GTAB in their 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 treat the GTAB as if were imported gasoline and complete all requirements for gasoline manufacturers 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.
      (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.
§1090.1650 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 PTDs stating that the fuel is for "export only" under subpart K of this part. Fuel manufacturers must keep 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 under this part even if it will later be exported.
      (c) Fuel that has been classified as American Goods Returned to the U.S. by the U.S. Customs Service is not considered to be imported for purposes of this part, provided all the following requirements are met:
      (1) Such fuel was produced at a fuel manufacturing facility located within the United States and has not been mixed with fuel produced at a fuel manufacturing facility located outside the United States.
      (2) Such fuel must be included in compliance calculations by the producing fuel 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.
