The procedures specified by this chapter shall be used to evaluate the effectiveness of a facility’s quality assurance (QA) and quality control (QC) procedures for COMs. The procedures specify the minimum quality assurance requirements for the assessment and control of COM data. Source owners and operators using COMs shall meet these minimum requirements and are encouraged to develop and implement a more extensive QA and QC program or to continue the programs where they already exist. Data collected as a result of QA and QC measures required in this chapter shall be submitted to the Department. The data shall be used by both the Department and the owner or operator in assessing the effectiveness of the procedures in maintaining acceptable operation and valid emission data. All sources using COMs shall develop and implement the required QC plan upon successful completion of the initial performance specification test and shall conduct the required QA procedures beginning with the first calendar quarter following the successful performance specification test. These procedures explicitly specify the quality assessment methods to be used for calibration drift and quality audits but do not address the evaluation of monitor installation location or the design specification verification procedures which are addressed in Appendix B of 40 CFR Part 60.
