EnvironAir Asia, Inc. (EAI) is able to evaluate stack emissions sampling and testing from various industrial processes. We offer the highest quality standard in the sampling of emissions.

  • Industrial Stack Emission Analyses
  • Isokinetic Analyses
  • Emission sampling and flow measurements according to US-EPA (Environmental Protection Agency) reference methods.

Gaseous and particulate pollutants: NOx. SO2, and PM

2.4   Stationary Sources

2.4.1. General

All stationary sources of air emissions must comply with National Emission Standards for Sources Specific Air Pollution (NESSAP) and Ambient Air Quality Standard (AAQS)  pertaining to the source. Additional requirements are summarized in the following paragraphs. “Stationary Sources” may generally be defined as individual points of air emissions (e.g. smokestacks).
