© 2009 Cemtek Environmental, Inc. Regulations, where do we stand? Since vacating the Clean Air Mercury Rule (CAMR), the implementation of mercury monitoring has primarily fallen on the state and local regulators. The EPA often uses Consent Decrees to mandate mercury monitoring. The cement industry is currently under review by the EPA to slash mercury emissions. Mercury

NON-COMPLIANT OPACITY PROCESS MONITOR CEMTEK Instruments Model 6000 & 6010

© 2009 Cemtek Environmental, Inc. Many Plants have multiple Boiler configurations feeding into a main stack. Individual Boiler outlets allows for the determination of any emissions violation at the source. Multi-Unit applications can utilize non compliant opacity monitors to detect individual excursions seen as an overall increase with the Stack Monitor. Accurate measurement of individual boiler opacity may avoid any excursion over the permitted limit imposed on the plant since detection at the onset of incomplete combustion. Energy reduction measures are incrementally reduced as the opacity stays below a preset threshold. CEMTEK Instruments Model 6000 & 6010
