§ 75.8 - Relative accuracy and availability analysis.

(a) The Agency will conduct an analysis of monitoring data submitted to EPA under this part between November 15, 1993 and December 31, 1996 to evaluate the appropriateness of the current performance specifications for relative accuracy and availability trigger conditions for missing data substitution for SO2 and CO2 pollutant concentration monitors, flow monitors, and NOX continuous emission monitoring systems.

(b) Prior to July 1, 1997, the Agency will prepare a report evaluating quarterly report data for the period between January 1, 1994 and December 31, 1996 and initial certification test data. Based upon this evaluation, the Administrator will sign for publication in the Federal Register, either:

(1) A notice that the Agency has completed its analysis and has determined that retaining the current performance specifications for relative accuracy and availability trigger conditions are appropriate; or

(2) A notice that the Agency will develop a proposed rule, based on the results of the study, proposing alternatives to the current performance specifications for relative accuracy and availability trigger conditions.

(c) If the Administrator signs a notice that the Agency will develop a proposed rule, the Administrator will:

(1) Sign a notice of proposed rulemaking by October 31, 1997; and

(2) Sign a notice of final rulemaking by October 31, 1998.
