- 0135 Subject: Supplemental Proposed Regulations: Performance Based Measurement S ystem Date: 12/21/2011

The following are proposed regulations as discussed in section i. ii , Option 2, Agency Approval of All Test Methods, in the preamble of this proposed rule.

5. Section 80.47 is revised to read as follows:

**§ 80.47 Performance Based Analytical Test Method A**  **pproach.**

All sample handling, testing procedures and tests must be conducted using good laboratory practices.

(a) Definitions. As used in this subpart: ( 1 ) Performance

- based Analy tical Test Method Approach means a measurement sy stem based upon establish ed performance criteria for accuracy and precision with use of anal yt ical test methods. As used in this subpart, a measurement s ys tem used by laboratories to demonstrate that a particular anal yt ical test method is acceptable for demonstrating compliance. ( 2 ) Accuracy means the closeness of agreement between an observed value from a single test measurement and an accepted reference value. ( 3 ) Precision means the degree of agreement in a set of measurements performed on the same propert y of identical test material. (4) Absolute fuel parameter means a fuel parameter for which a gravimetric standard is practical to construct and use. Sulfur content of gasoline, butane, or diesel fuel are examples of an absolute fuel parameter. (5) Gravimetric standard means a test material made by adding a carefull y weighed quantity of the anal yt e to a measured quantity of another substance known not to contain any of the anal yt e, resulting in a solution with an accurately known concentrate of the anal yt e. (6) Consensus named fuels are homogeneous quantities of fuel that have been anal yz ed b y a number of different laboratories (b y sending around small samples). The average concentration of some parameter of interest across all of the different laboratories is then used as the “consensus name” for that material. (7) Locally

- named reference materials are gasoline or diesel fuels that are usually from the regular production of the facility where they

are used in laboratory

quality control efforts and have been anal yz ed using the designated method (either by the facility’s lab or by

a referee lab) to obtain an estimate of their concentratio n. (8) Method

- defined fuel parameter means a fuel parameter for which an EPA

- prescribed primary test method or “designated method” defines the regulatory standard. Examples of method

- defined fuel parameters include olefin content in gasoline, Reid vapor p ressure (RVP) of gasoline, distillation parameters of gasoline, benzene content of gasoline, aromatic content of gasoline and diesel fuel, and oxygen/ox ygenates content of gasoline.2

(9) Reference Installations are designated test method installations that are used to qualify the accuracy

of other method

- defined parameter instruments. Reference installations of the designated test method will be used to evaluate the accuracy of other method

- defined alternative test methods and to establish correlation equ ations if necessary

. (10) Correlation equation is a correction equation as determined by the use of ASTM International standard practice D6708 (incorporated by reference, see paragraph (r) of this section). This standard practice determines whether the co mparison between the alternative test method and the designated test method is a “null” result. If the comparison is not “null’, then the standard practice provides for a correlation equation that predicts designated test method results from the applicabl e method

- defined alternative test method. (11) Statistical quality

control (SQC) means a planned sy stem of activities whose purpose is to provide a level of quality that meets the needs of compliance with the standards of Part 80. This subpart prescribes specific SQC requirements for both absolute and method driven fuel parameters for both VCSB and non

- VCSB regulated parties. (12) Voluntary

consensus

- based standards body (VCSB) means a domestic or international organization that plans, develops, establishes, or coordinates voluntary consensus standards using agreed

- upon procedures and which possesses the attributes of openness, balance of interest, due process, and consensus, as explained in OMB Circular A

- 119 and the National Technology

Transfer and Advancement Act of 1995, P.L . 104

- 113, sec. 12(d). (13) Non

- Voluntary

consensus

- based standards bod y (non

- VCSB) means a domestic or international regulated party whose anal yt ical test method is not adopted by a VCSB organization.

(5) If the use of ASTM D6708 (incorporated b y reference, se e paragraph (r) of this section) reveals that the candidate method

- defined non

- VCSB test method has sample

- specific biases due to matrix effects that cannot be determined as random the method is disqualified. If however, it is determined that the candidat e method

- defined non

- VCSB test method can be qualified on a narrow circumscribed range of fuels while still meeting the data requirements for variability as required in ASTM International D6708 (incorporated b y reference, see paragraph (r) of this section) (see (m)(3)), then the ty pes of fuels on which the qualification was achieved and for which the method is to be approved must be specified in the candidate method

- defined non

- VCSB test method description. If there is any restriction on the scope of fuels for which the candidate method

- defined non

- VCSB test method is to be qualified, the applicant must include a discussion of how the facility plans to screen sample for conformity to the scope. If the candidate method

- defined test method is found to have m inimal matrix effects, a statement to this effect must be included by the applicant in its application. (6) The candidate method

- defined non

- VCSB test method precision qualification must be conducted in the form of “cross

- method reproducibility ” (Rcm) of the candidate method and applicable designated test method as required in ASTM International D6708 (incorporated b y reference, see paragraph (r) of this section), where the Rcm must be equal to or less than 70 percent of the published reproducibility of the applicable designated test method. (7) The applicant of the candidate method

- defined non

- VCSB test method must demonstrate through the use of ASTM D6708 (incorporated by reference, see paragraph (r) of this section) whether a correlation to applicable des ignated test method is necessary . If it is determined through the use of this practice that the candidate method

- defined non

- VCSB test method requires a correlation equation in order to predict designated test method results, then this correlation equatio n must be applied to the candidate instruments output to obtain measurement results for regulatory purposes. (8) Any

additional information requested b y the Administrator and necessary to render a decision as to approval of the test method.

y the applicant of the reasons for not approving the method. If the Administrator does not notify the applicant within 90 day s of receipt of the application, then the test method shall be deemed approved.12
