Title

Zeneca/Former Stauffer Chemical Site - Lot 1 PCB/VOC Area Removal Action Workplan

Description

The Zeneca/Former Stauffer Chemical Company Site (Zeneca Site also referred to as the Campus Bay Site). The Zeneca Site was first developed in 1897 when Stauffer Chemical Company (Stauffer) built a plant to manufacture sulfuric acid. Later, Stauffer also manufactured at various times Superphosphate, carbon disulfide, aluminum sulfate, ferric sulfate, titanium trichloride, and agricultural products. These manufacturing activities occurred predominantly on Lots 2 and 3 of the Zeneca Site and these manufacturing operations ceased in 1997. Prior to the 1950's Lot 1 appears to have been used as a farm, a school and for residential buildings. Stauffer Chemical began development of Lot 1 in the late 1950's with the construction of a pilot metals research facility. Electron beam furnaces were used to melt various metals. For a two-week period, uranium ingots may have been melted in a furnace located in former Building 80, and was previously reported that it may have been melted in a furnace located in former Building 94. More recent information indicates that the uranium ingot was melted in the former Building 80. Both buildings have been demolished and Building 94 was located to the north of the Lot 1 PCB/VOC area. The former Building 80 was located to the south on Lot 3. In the 1960's development of Lot 1 as an agricultural chemical research and development campus began. Agricultural chemical research and development continued until 2001 and included the use of solvents, pesticides, metals and some radioactive substances. Other historical activities that occurred in the general vicinity of the PCB/VOC Area included a hazardous materials storage area, and an electrical transformer. Residual cinder material from the sulfuric acid manufacturing has been detected at Lot 1. Lot 1 currently consists of office buildings, greenhouses, fences, parking areas, sidewalks, and vacant land.
