Domenico Cipriano*, Costanza Scacchi* Conferenza Internazionale sul Monitoraggio alle Emissioni Panama City, Florida, 8-13 Marzo 2009 PRESENTAZIONE POWER POINT * CESI RICERCA The United States Environmental Protection Agency’s (EPA) Clean Air Mercury Rule (CAMR) includes provisions related to use of mercury (Hg) continuous emission monitoring systems (Hg CEMs) to measure Hg emissions from coal-fired electric utility steam generating units. Among these are the Hg monitoring additions to 40 CFR Part 75 and a new Appendix B Performance Specification for 40 CFR Part 60 – “Specifications and Test Procedures for Total Vapor Phase Mercury Continuous Emission Monitoring Systems in Stationary Sources” (PS-12A). Both of these provisions require a CEM certification process that includes a Relative Accuracy Test Audit (RATA) using an approved EPA reference method (RM). The goal of proposed project is develop hardware for a performance-based instrumental reference method that would be consistent with the NOx and SOx instrumental methods, would be modular, portable and affordable, and allow Hg RATA testing to be performed in two days of less. Recognizing the fact that EPA is currently working on several conceptual IRM configurations that are based on the existing technologies, authors propose a complementary but different approach: the existing technology, developed in the U.S. and EU, are combined and modified to provide a modular, flexible and affordable IRM system that would meet EPA and industry objectives concerning RATA testing and Hg CMM certification, and could also be configured for other uses, such as: traversing, field testing and certification of a Hg analyzer using the wet chemistry Reference Method. Preliminary results from a field test are shown in the work.
