Regulatory Support

Pulp & Paper

NCASI technical resources related to major rulemakings in the Pulp and paper sector, viz., the Subpart S (pulp and paper) MACT, Subpart S RTR, Subpart MM (chemical recovery) MACT and RTR are available here. Leading up to the Subpart S rulemakings, NCASI conducted an extensive sampling program to quantify HAP emissions from pulp mills, helped develop the HAP/methanol collection requirements in condensates, and developed guidance documents on condensate characterization and establishing averaging times for condensate collection. NCASI has also developed guidance documents related to bleach plant testing using modified method 26A (NCASI method to measure Cl in the presence of ClO2). Resources related to these and other regulatory support activities are available here.
