Welebir, R.S., MPH I Director of Environmental HealtbE FROM: Robert Solid Waste Management Specialist 1946N. -M Ulm Prior to the keeping of Health District records and between the years 1910 and 1955, a brick factory was operated on the 21 -acre site by California Clay Products. A massive excavation was developed on the southeastern 10 acres of the site where clay for brick manufacture was removed to a base depth of approximately 20 feet. Upon cessation of brick -making operations, the clay quarry was made available for<Commercial disposal of Class III> materials. Large volumes of concrete and building demolition from the downtown Stockton rehabilitation pftject were disposed at the site. Districtes relative to the site ornated in 1973.� it was at this time that three acres along the eastern edge of the original excavation were made available to Learner Company - a local automobile salvage and demolition firm. Learner Company disposed of its non-salvagable automobile demolition wastes con- sisting primarily of foam, rubber, and plastics. The California Regional Water Quality Control Board required geological and hydrological data to be submitted by California Clay Products for the purpose of drafting waste discharge r uirements for the operation of a limited Class II disposal sitP Affidavits were submitted by a CalMi_nia Clay Products employee and a local well driller attesting to the impervious nature of the soil and the water table depth.
