Mr. Vadimsky stressed that Macho will become a minor source of volatile organic chemicals (VOCs) when the new facility is placed in operation because the level of emissions will decrease significantly. Mr. Vadimsky showed a diagram of the proposed 38,000 square foot plant and pointed out the storage and mixing area. He explained that the processing areas will be separated from the main facility by firewalls. The storage and mixing area will have a depressed floor with a ramp into it and a containment dike that could contain the worst possible spill. All of the containers are non-tippable stainless steel drums on welded steel legs. The most that could spill in that area would be a 10- or 15 - gallon container. Further, if for some reason one of the containers burst completely, the dike would contain the spill. All nine containers would have to burst before the spillage reached the height of the curb, and this has never happened. Mr. Vadimsky stressed that the rest of the building is pressurized with filtered fresh air. When the incinerator is put into the process, it will have complete control over all the other devices, and if anything should fail in the system, everything would automatically stop except the exhaust fans. The fans would keep running in order to prevent any buildup of solvent in the air that might become hazardous. Storage of the solvent will be in a 6,000 -gallon fiberglass tank with a containing dike around it, which Mr. Vadimsky compared with local gasoline tanks that contain between 25,000 and 30,000 gallons of fuel. John Marcheschi, environmental product manager of Stelter and Brinck, Cincinnati, Ohio, came before the Board to describe his company's role in the proposed facility. Mr. Marcheschi advised that Stelter and Brinck was founded in 1956, and he has been with the company for the past 6 years since obtaining his bachelor's degree in chemical engineering from Vanderbilt University. Mr. Marcheschi explained that the emission control device is actually a catalytic converter which converts the chemicals to harmless compounds:{'The catalytic convertor is -similar in some ways to the catalytic converters in automobiles. When an engine burns gasoline, the gasoline itself is inorganic. However, it is not burned completely and the residual organic compounds must be converted to harmless compounds before being released into the atmosphere. However, an automobile catalytic converter emits carbon monoxide, which is harmful. The Macho incinerator is much safer in that it will not release any carbon monoxide, but instead converts the chemicals to carbon dioxide and water. No cloudiness will be seen coming out of the building. There will be some heat 23 T JAN 1. 2 1993 BOOK •'uL 4,9
