40 CFR Part 75 Continuous Emission Monitoring, Appendix K, "Quality Assurance and Operating Procedures for Sorbent Trap Monitoring Systems" specifies sampling, analytical, and quality-assurance criteria and procedures for performance-based monitoring of vapor-phase Hg emissions in combustion flue gas streams, using a sorbent trap monitoring system. The principle employed is continuous sampling using in-stack sorbent media coupled with analysis of the integrated samples. This performance-based approach allows for the use of various suitable sampling and analytical technologies while maintaining a specified and documented level of data quality through performance criteria.
The analyte measured is total vapor-phase Hg in the flue gas, which represents the sum of elemental Hg and oxidized forms of Hg, in mass concentration units of micrograms per dry standard cubic meter (µg/dscm).
Known volumes of flue gas are extracted from the stack through paired, in-stack, pre-spiked sorbent media traps at an appropriate nominal flow rate (Collection of Hg on the sorbent media in the stack mitigates potential loss of Hg during transport through a probe/sample line). Paired train sampling is required to determine measurement precision and verify acceptability of the measured emissions data.
