QA - Annual Performance Evaluation ---------------------------------- 40 CFR Part 58 Appendix A section 3.2.2 requires the PQAO, each calendar quarter (during which monitors are operated), evaluate at least 25 percent of the SLAMS monitors for SO2, NO2, O3, or CO such that each monitor is evaluated at least once per year. The evaluation is made by challenging the monitor with audit gas standards of known concentration from at least three of ten audit levels. The audit levels selected should represent or bracket 80 percent of ambient concentrations measured by the monitor being evaluated. Each audit level has a minimum and maximum concentration range, with the lowest range defined as audit level 1. For the criteria gases, 10 audit level ranges are currently defined. AQS evaluates each reported assessment concentration on the transaction with its reported level number. If the concentration is not within the level's concentration range, then AQS will produce a warning message when processing the transaction. The concentration values and reported level number will be stored in the database and a warning will be issued on the error report produced by the batch load process. The maximum and minimum allowable reported values defined for the parameter would also apply, and produce rejections if exceeded.
