The United States Environmental Protection Agency (EPA) Emissions Standards Division (ESD) requested that the EPA's Emission Monitoring and Analysis Division (EMAD), Emission Measurement Center (EMC) provide testing support in the investigation of the reinforced plastics composite manufacturing source category to properly set the Maximum Achievable Control Technology (MACT) standards as required by the Clean Air Act Amendments of 1990. The Reinforced plastics composite manufacturing process located at LASCO Panel Products in Florence, Kentucky was selected by the ESD as the host facility for this emissions testing program. The sampling program was designed to support the following ESD objectives: (1) Identify and quantify the hazardous air pollutants (HAPs) emitted by reinforced plastic manufacturing, (2) Identify the sources of HAPs and the total HAPs mass emission rates from the wet applications and the oven area, (3) Evaluate three ventilation scenarios, (4) Depending on the effectiveness of the industry proposed 'closed' system, develop a performance-based emission limitation achieved by the use of a wet area enclosed table system, (5) Assess the existing emission factors for volatile organic compound emissions from a continuous lamination process for the purposes of updating the information in AP-42 and determining cost effectiveness for MACT options involving emissions abatement, and (6) Determine the effect of various process parameters such as line speed, laminate thickness, HAP content of raw materials and the addition of a gel coat layer on the emission factor. Sampling was performed during 13 process operating conditions. Measurements were made of the total hydrocarbons (THC), styrene, cumene, and methyl methacrylate (MMA), and the air flow rate at all enclosure exhausts. A secondary objective of the sampling program was to obtain the emissions of HAP's from the oven stacks. This volume (Volume III) is comprised of 799 pages and consists of Appendices B
