1/5/2015 Perry called to report that the precipitator has been rebuilt and is now up and running. Stack testing and Method 9 observations are also now taking place. Most all observations have shown 0% opacity with 10% being the highest observed. Perry also reported that the CPMS (PEMS) system is now fully functional and is tied to their DAS system. DAVID KNOLL
