Subject:	Supplemental Proposed Regulations: Performance Based Measurement System 
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 Approach.

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

(a)	Definitions.
As used in this subpart:
(1) 	Performance-based Analytical Test Method Approach means a measurement system based upon established performance criteria for accuracy and precision with use of analytical test methods.  As used in this subpart, a measurement system used by laboratories to demonstrate that a particular analytical 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 property 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 carefully weighed quantity of the analyte to a measured quantity of another substance known not to contain any of the analyte, resulting in a solution with an accurately known concentrate of the analyte.
(6)	Consensus named fuels are homogeneous quantities of fuel that have been analyzed by a number of different laboratories (by 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 analyzed using the designated method (either by the facility's lab or by a referee lab) to obtain an estimate of their concentration.
(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 pressure (RVP) of gasoline, distillation parameters of gasoline, benzene content of  gasoline, aromatic content of  gasoline and diesel fuel, and oxygen/oxygenates content of gasoline.
(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 equations 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 comparison 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 applicable method-defined alternative test method. 
(11)	Statistical quality control (SQC) means a planned system 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 body (non-VCSB) means a domestic or international regulated party whose analytical test method is not adopted by a VCSB organization.

The facility must construct "MR" and "I" charts with control lines as described in section 8.4 and appropriate Annex sections of this standard practice.  In circumstances where the absolute difference between the mean of multiple back-to-back tests of the standard reference material and the accepted reference value of the standard reference material is greater than 0.75 times the published reproducibility of the test method must be investigated by the facility.  Records of the standard reference materials measurements as well as any investigations into any exceedance of these criteria must be kept for a period of 5 years.
(2)	(i) Precision SQC.  Each facility on every instrument tests a quality control material as defined in paragraph 3.2.3 in ASTM International D6299 (incorporated by reference, see paragraph (r) of this section) either once per week or once per every 20 productions tests, whichever is more frequent.  The facility must construct and maintain an "I" chart as described in section 7 and section A1.5.1 and a "MR" chart as described in section A1.5.2.
