The A&F Materials site is located on three and three-quarter acres in Greenup, IL. The site, originally an undeveloped backwater flood zone for the Embarras River, was first developed for a sawmill operation. Mr. Ken Ault purchased the site for the A&F Materials recycling plant, which began operations in March 1977 and continued until it shut down in 1980. The plant processed waste materials (including but not limited to oil, sludge, caustic and sulfuric acid) into fuel oil and fire retardant chemicals. During the course of operations, there were numerous violations of the operating permit issued to the plant by the IEPA. By March 1978, four storage lagoons became filled and began to overflow, contaminating the soil and drainage pathway. In addition, thirteen steel storage tanks containing a mixture of waste oils (contaminated with PCBs and organics), sludges, spent caustics and acids, contaminated water and other waste products, were located onsite. The most significant contaminants of concern found during the RI/FS include: sulfates, inorganics, TCE, and metals.
