Continuous Emission Monitoring Systems Services

Continuous monitoring systems (CMS) have become a critical part of a facility’s ongoing compliance demonstration.  U.S. EPA and individual states agencies are focused on expanded transparency, increased scrutiny, and the use of data analytics and targeting for enforcement purposes.  This makes effective CMS management more crucial than ever before.

Businesses that prioritize continuous monitoring — and work with external consulting firms who know how to align system integration and data management with their strategic goals — will be better positioned to succeed in an increasingly complex and technical regulatory environment.

What Is a Continuous Monitoring System?

A Continuous Monitoring System is a tool that continuously measures and records actual data and information from an emissions source.  The measured data is often used in real-time to operate the source and also demonstrate compliance with applicable regulations. A CMS must meet specific criteria depending on the nature of your operation, which may include formal certification.

The U.S. EPA distinguishes between four types of CMS:

  • Continuous emission monitoring systems (CEMS): To directly measure actual emission levels from a stationary source, such as nitrogen oxides of a flue-gas.
  • Continuous emission rate monitors (CERMs):A sub-type of CEMS that measures pollutant rates in a standard such as mass per unit time.
  • Continuous opacity monitoring systems (COMS):A relative indicator of particulate matter emissions by measuring the opacity of flue-gas.
  • Continuous parametric monitoring systems (CPMS):To measure a specific parameter(s) and also used to extrapolate emissions data from it.

continuous emissions monitoring system data with factory smoke

  • Changes to 40 CFR Part 60, Part 63 or Part 75, or other governing regulations
  • Poor data availability or quality, or changing data end use
