Efforts in this area of NCASI’s program are oriented towards developing a) technical work products that inform regulatory agencies during rule development and b) rule summaries, guidance documents and implementation tools to assist members during rule implementation (Pulp & Paper Manufacturing and Wood Products Manufacturing).

NCASI technical resources related to the Boiler MACT rulemakings are available here. Notable NCASI work related to this topic includes an assessment of the performance of PM CEMS on wood-fired boilers, summary of Detection and Quantitation limits for mercury (Hg) measurement, guidance on fuel sampling and analysis and summary contaminant…

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…

EPA issued the Plywood and Composite Wood Panel Maximum Achievable Control Technology (PCWP MACT, 40 CFR Part 63, Subpart DDDD) emission standards in July 2004. These standards established hazardous air pollutant (HAP) emission limits for certain panel plants and engineered lumber operations that are major sources. EPA is currently reconsidering…

This NCASI Excel-based tool was developed to audit test reports that utilize US EPA Method 5 to determine particulate matter emissions from a stationary source.
Learn MoreNon-Hazardous Secondary Material Self-Determination Certain materials were granted categorical non-waste status (Scrap tires, resonated wood, coal refuse, and dewatered pulp and paper sludges that are combusted on-site) in the Federal Register on February 7, 2013 . Three additional categories were proposed (c
Learn MoreCarbon Monoxide Floor Determinations During the setting of the MACT floor for carbon monoxide, Ncasi added to EPA's understanding in several areas where the procedures originally used were not scientifically valid. Alternative limits for boilers equipped with CO CEMS The initially proposed Boiler MACT car

Learn MoreWet Scrubber pH Monitoring Boiler MACT requires boilers equipped with wet scrubbers and demonstrating compliance with the HCl limit by stack testing to monitor the pH of the scrubbing medium during the performance test and establish the operating parameter range based on this data. The pH of the scrubbing mediu
Learn MoreInitial Performance Tests NCASI has hosted several workshops on designing initial performance tests for multi-fuel boilers at various regional meetings. These workshops were held in the form of interactive panel discussions, with illustrative case studies also provided as discussion aids. Please contact Vipin
Learn MoreEPA Method 30B to Determine Mercury (Hg) Emissions Among the methods approved for mercury emissions performance testing in the Boiler MACT rule, only EPA Method 30B offers the combination of low detection limits, ease of implementation and low implementation costs. Given these benefits, there is an incentive in
Learn MoreElectronic Reporting Tool All performance test results must be submitted to EPA’s Central Data Exchange (CDX) using the Electronic Reporting Tool (ERT). The Test Plan portion of the ERT must be filled out first. Only after that will the Test Data section become available. Filling out the test plan portion pr
