Continuous Emissions Monitoring Guide

Harlan H. Bengtson, PhD, P.E.

Course Outline

The Part 75 continuous emission monitoring rule, found in 40CFR, was originally published in January, 1993.  The purpose of the regulation was to establish continuous emission monitoring for air pollution, and to report requirements under EPA’s Acid Rain Program, which was instituted in 1990 under Title IV of the Clean Air Act.

The Acid Rain Program regulates electric generating units that burn fossil fuels and that serve a generator greater than 25 MW.  For such units, Part 75 requires continuous monitoring and reporting of SO2 mass emissions, CO2 mass emissions, NOx emission rate and heat input.  The SO2 component is a “cap and trade” program, designed to reduce acid deposition by limiting SO2 emission levels in the “lower 48” states of the United States.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
