Daily & Weekly Data System Review

These recommendations are not based on any regulatory requirements, but on gathered knowledge and experiences collected from many CEM operators. Each day you should perform this quick review of available information on the status of the CEM system so you can determine if anything needs immediate attention, attention sometime today, or no attention at all.

Daily and Weekly Data System Review:

1. Find the reports which are generated automatically overnight. Look these reports over and respond as needed.

  • Calibration Detail Report - shows the results from the morning’s daily calibration check. Any monitor which shows that it failed its calibration requires immediate attention. Any monitor which shows that the calibration results were at or above the maintenance limits, requires attention and possible adjustment sometime today before your shift ends. Remember, if an adjustment is made, a follow up “hands off” successful calibration check is required by CEM regulations.
  • Average Data Report - shows the measured hourly averages for the data from the monitors from yesterday.
  • A second Average Data Report - shows the derived (calculated) hourly values from yesterday.
  • Process Now History Report - documents any error encountered when the various Process Now sequence ran earlier today.
  • Other reports might be generated as well, showing extended averages (3-hour, 24-hour, 30-day, etc.), year-to-date totals, or the results of other calculations.
2. Review the status of the CEM system with the control operator and see if there are any CEM system alarms up and present.

3. On Thursday or Friday, make a trip to the shelter and make sure everything looks good. Look over the air clean up system and make sure it’s in good shape. Double-check the pressure in the calibration bottles and make sure they’re > 500 psi to get the calibration checks through Monday.

Having a set of previously developed procedures and other support documents will help manage the burden created by these obligations. For questions, suggestions, or for a general chat, please do not hesitate to contact me.
