(ii) **The mean, median, and range expressed in appropriate units for each measured fuel parameter.** - (iii) **The standard deviation for each measured fuel parameter.** - (iv) The estimated compliance rate for each measured fuel parameter subject to a per-gallon standard in subpart C or D of this part. - (v) **A summary of potential noncompliance issues.** - (4) Any other information as EPA may require in order to administer reporting systems. - (d) **NSTOP quarterly reporting.** An independent surveyor conducting the NSTOP under [§ 1090.1450](/cfr/40/1090.1450.md) must submit the following information quarterly, as applicable: - (1) **For each gasoline manufacturing facility sampled by the independent surveyor—** - (i) The EPA-issued company and facility identifiers for the gasoline manufacturer and the gasoline manufacturing facility. - (ii) [Reserved] - (2) **For each gasoline sample collected by the independent surveyor—** - (i) **The designation of the gasoline.** - (ii) **The date and time the independent surveyor collected the sample.** - (iii) The batch number or the sample identification number as assigned by the independent surveyor in a consistent manner and as specified in the survey plan. - (iv) A description of any instance in which the gasoline manufacturer did not follow the applicable sampling procedures. - (v) The test results for the sample, and the test methods used, as determined by the independent surveyor, including the following parameters: - (A) **The sulfur content, in ppm.** - (B) **The benzene content, in volume percent.** - (C) **The RVP in psi, if tested.** - (vi) The test results for the sample, and the test methods used, as determined by the gasoline manufacturer, including the following parameters: - (A) **The sulfur content, in ppm.** - (B) **The benzene content, in volume percent.** - (C) **The RVP in psi, if tested.** - (vii) If available, the test results for the sample, and the test methods used, as determined by EPA's National Vehicle and Fuel Emissions Laboratory, including the following parameters: -
