The United Scrap Lead (USL) site is located in a sparsely populated area approximately one mile south of the City of Troy, Concord Township, Miami County, Ohio. From 1946 to 1980, the site was used by a lead reclamation business, reclaiming lead from used automobile batteries and selling it to lead shelters. The lead reclamation operation involved the separation of the batteries from their casings and tops, collection of the lead plates for reprocessing, and the disposal of the tops and castings onsite. The acid was originally discharged directly to an acid seepage field, but beginning in late 1972, the acid was neutralized with ammonia prior to discharge. The site first came to the attention of authorities in June 1967 when USL requested a permit to continue to dispose of the battery casings in the back portion of the property. Subsequent testing of the wastewater indicated high levels of lead, cadmium, and other toxic materials. In November 1985, the EPA Region V Emergency Response Section initiated an emergency removal action. This action removed the contaminated soil and waste materials from the immediate vicinity of the surrounding residences and placed them in a large pile onsite. The primary contaminants of concern affecting the soil and sediments include lead. The selected remedial action for this site is given.
