Appendix A CEMS Inspection Sheet
9. Optional Control Equipment Parameter Monitoring (' 75.34)
What to Check
Check the QA/QC Plan which will identify add-on SO2 or NOx control equipment parameters and acceptable ranges if the source is using add-on control equipment missing data options. Parameters and acceptable ranges are required by App B, ' 1.1.1.
Review control equipment parameter monitoring records for a number of missing data periods. Compare the parameter data to the acceptable ranges in the QA/QC Plan. Identify any periods when the range is exceeded and how the missing data period was flagged in the DAHS (control operating properly or not operating properly).
Ask the source how it enters proper control equipment operation for missing data periods into the DAHS. Manual entry of missing data period information is allowed by Part 75.
