Federal and state regulations require industrial emission sources to obtain air permits and install emission control equipment sufficient to meet or maintain regional air quality standards, equipment performance standards, and/or categorical industry emission limits. Emission testing – or stack testing – is recognized as the most accurate method for determining air emissions and determining source compliance with the regulatory requirements.

EQM’s Emission Measurement Division has been conducting air emission and stack testing for 30 years at virtually all types of industrial sources. Our experienced team is well-versed in all EPA test methodologies and with permit and compliance issues – EQM can apply these techniques for any industry under nearly all temperature, pressure, pollutant concentration, and gas flow conditions. Our mobile stack testing laboratories and in-house services for gravimetric and wet chemistry (titration) analyses, liquid/gas VOC response factor development, and equipment calibration result in turn-key emission measurement services.
