Appendix A CEMS Inspection Sheet
What to Check
Ask the source if there have been any changes since the last audit or certification/recertification. Document the serial numbers and compare to those in the monitoring plan.
What is the status of the control panel lights, indicators and alarms? Displays will vary by analyzer, so ask the source what the displays are and what they mean.
Check range settings, and compare to the monitoring plan. Has the source done the annual span/range check required by App. A?
Compare the sample flow rate, if displayed by a rotameter (or a digital reading), to the QA/QC Plan.
Have there been any changes to correction factors (NOx quenching and moisture monitors) since the last RATA? Changes to correction factors should be recorded in the maintenance log, and the QA/QC Plan should outline the procedures for changing the correction factors (Appendix B, Section 1.1.3). QA testing may also be required (See '75.20(b), and Recertification and Diagnostic Testing Policy).
