The purpose of these one to two page summaries are to offer suggestions for how to perform these reviews or key points to remember when conducting these activities. They are also intended as a starting point or a template for ESC customers to develop their in-house and site specific procedures, check lists, or other helpful tools for people to use.

These summaries are not “all encompassing” and do not contain every relevant piece of information on these topics. As always, operators of CEM systems should consult the:

  • Actual regulations, such as:
    • Part 75
  • The Part 75 Policy Manual, and
  • The "Plain English Guide to Part 75"
  • CEMS operators should also consult the reporting instructions for Quality Assurance and Certification records. A link to the updated Monitoring Plan reporting instructions is provided below

One of the key elements to establishing clean and consistent emission data sets is the ability to process and operate the processes that are being monitored (the boilers, combustion turbines, reagent injection systems, Selective Catalytic Reactors (SCRs), Wet Flue Gas Desulfurization (WFGDs)), etc... and the CEM systems present in a consistent manner.

Be aware that many facilities operate CEM systems that records emission readings to show or demonstrate compliance for several different reporting programs simultaneously. The most common examples are SO2, NOx, CO2/O2 monitors for both Part 60 and 75. Frequently, reporting systems have duplicate parameters within their CEM configuration, one set for P60 reporting and the other for P75 reporting. Operators of diluent (CO2 or O2) and volumetric flow monitor systems also need to be aware that the data generated by these systems are frequently used in the derived calculations for Hg, PM, HF or HCl reporting for P63 (the EGU MATS reporting rule).
