Part 75 – The Overview

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

  • 40 CFR Part 75, Continuous Emission Monitoring (Actual Regulations)

  • 40 CFR Part 75, Emissions Monitoring Policy Manual

  • Plain English Guide to the Part 75 Rule

  • StackVision User Guide, found within the StackVision application (Main Menu > Help > StackVision Help)

One of the key elements to establishing clean and consistent emission datasets is the ability to understand and manage the monitored processes for: boilers, combustion turbines, reagent injection systems, Selective Catalytic Reactors (SCRs), Wet Flue Gas Desulfurization (WFGDs), and the CEM systems.

Be aware that many facilities operate CEM systems that record 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).

These overlapping regulations can lead to complexity, confusion, and frustration, but this is where using checklists or having in-house procedures gives you a chance to keep a handle on these issues and allows you to address the overlapping regulations successfully.
