The United States Environmental Protection Agency (EPA) Emission Standards Division (ESD) is investigating the lime manufacturing industry to identify and quantify hazardous air pollutants (HAPs) emitted from lime kilns. ESD requested that EPA's Emissions, Monitoring and Analysis Division (EMAD) conduct the required testing. EMAD issued a work assignment to Pacific Environmental Services, Inc. (PES) to conduct a 'screening' test to collect air emissions data as specified in the ESD test request. The primary objective of the testing program was to characterize emissions of selected hazardous air pollutants (HAPs) from Kiln No. 1 located at the National Lime & Stone Company in Carey, Ohio. Based on the pollutant concentrations and emission rates calculated from the results of the screening tests, the kiln may be selected by EPA for further testing. The tests were conducted to quantify the uncontrolled and controlled air emissions of hydrogen chloride (HCI), total hydrocarbons (THC), and polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDDs/PCDFs). Testing was conducted on September 2, 1998. One test run was conducted at the scrubber inlet and scrubber outlet (stack); inlet and outlet testing was performed simultaneously. Concurrent with the PCDDs/PCFDFs testing, sampling was conducted at the stack breeching to determine concentrations of oxygen (O2), carbon dioxide (CO2), and total hydrocarbons (THC). During the testing program another EPA contractor monitored and recorded process and emission control system operation parameters.
