At Site 5 (continuing a numbering system initiated in a previous 4-site project) tests were only conducted for methods development purposes. At Site 6, emissions were measured at the inlet and outlet of the control device. At Site 7, an evaluation of CO and THC CEMSs was performed. At Sites 8 and 9, emissions were measured at the inlet of the venturi scrubber, at the midpoint located between the venturi scrubber and the wet ESP, and at the outlet of the wet ESP. For Sites 6, 8, and 9, midpoint and outlet air emission samples were collected and analyzed for particulate matter, metals, PCDD/PCDFs, volatile and semivolatile compounds (except Site 6), and hexavalent chromium and nickel subsulfide species. Continuous emission monitoring (CEM) for O2, CO2, CO, SO2, and NOx at the control system inlet and O2 (except Site 6), CO2 (except Sites 6 and 9), CO, SO2 (except Sites 6 and 9), NOx (except Sites 6 and 9), and THC was conducted at the control system outlet stack. The metals found in the greatest concentration in the sludge were lead, chromium and nickel. The need for sampling of hexavalent chromium without artifact formation and analysis of the resulting samples specifically for hexavalent chromium at low concentrations was a major accomplishment of the test program. The results of the nickel sampling and analysis indicate that within the detection limit of the wet chemical method, no nickel subsulfide was present in the air emissions. At Site 6 and Site 9, a positive correlation between carbon monoxide emissions and total hydrocarbon (THC) emissions was observed. At Site 7, a positive correlation was demonstrated between the 'Hot' and 'Cold' THC CEMs.
