What are Part 75 certification requirements for CEMS?

Part 75 certification requirements establish the accuracy of CEMS. A regulated facility or unit is required to perform the initial certification tests after CEMS installation and the ongoing certification tests thereafter to ensure the performance of the analyzers or monitors within the established standards. The initial certification tests include a 7-day calibration error check, linearity check, relative accuracy test audit (RATA), and response time. The DAS formula also needs to be verified. The ongoing certification tests include a daily calibration error (drift) check and daily flow monitor functional check. Quarterly tests are also to be performed according to the quality assurance protocol.  A relative accuracy test audit is required for each monitor semi-annually or annually.
