Emissions Monitoring (Stack Testing)


The furthest thing from any facility’s to-do list with a CEM system is to get on the bad side of a regulatory agency. First impressions are an over-looked but critical part of the emissions testing process, and a facility only has one shot at establishing this impression. We understand this, and are here to help your facility through the entire stack testing process to ensure you start and remain in compliance. Not only do we utilize state-of-the-art testing equipment and technology, but our clients also have the advantage of relying on our extensive familiarity with CEM systems and facility operations to assist facilities in process and emission optimization. This guarantees that our clients overcome any obstacles standing in their way of achieving compliance. After all, what good is a failed test?

We give our clients more than just numbers and test results; we bring an invaluable pool of knowledge to the process that allows for a comprehensive assessment of your specific situation. A typical testing process contains the following:

  • Permit interpretation and determination of required tests
  • Development of testing protocol
  • Submittal of testing protocol and negotiation with state agency
  • Conduction of necessary emissions testing field work
  • Evaluation of results
  • Compilation of final, defensible testing report
