Hazardous Air Pollutants (HAPs)

NCASI develops, evaluates and validates sampling and analytical methods for HAPs in air emissions, condensates and wastewater. Several of these methods are approved under the Subpart S (pulp and paper) and Subpart DDDD (PCWP) MACT rules for compliance demonstration purposes. The NCASI method to measure low levels of aldehydes and ketones in air emissions through derivatization (ISS-FP-A105.01) is one recent example.
