KLEINFELDER File No. 20-3978-O1.W10 July 26, 1997 13)Underground structures are or were historically present on site. These include below slab factory drains, the former underground beet flume, the truck and railroad scales, a suspected fuel oil or steam line (reference 1937 aerial photograph) leading to the former cottages along Yosemite Avenue, and the canals which formerly transported condenser water offsite. Due to the use of hazardous substances (such as parts cleaning solvent) within the factory, possible use of hydraulic oil in the railroad and truck scales, and the use of agricultural chemicals during the farming of sugar beets, it is possible that leakage from the drains, scales, beet flume or canals, may have impacted the site. Confirmation soil sampling should be conducted to verify that no contamination is present. 14)Four Spreckels owned PCB transformers are located on site. Additionally, there is a historical PG&E transformer location shown on Sanborn maps, and an existing PG&E transformer location on site. No visual evidence of leakage was noted at the existing transformer locations during our site reconnaissance. Spreckels should be requested to remove and properly dispose of their PCB transformers. PG&E should be contacted regarding removal of their transformer and testing for the presence of PCBs. Surface and shallow depth soil samples should be collected from the existing and historical transformer locations(after removal)and analyzed for PCBs and oils. 15)Spreckels Development Company has abated the asbestos containing materials from the former factory on site in preparation for demolition of the structure. According to Mr. Tucker, the existing administration building is to remain on site and used as a construction office for future development. Suspected asbestos containing materials were noted in the administration building during our site reconnaissance. An asbestos survey should be conducted of the administration building, and an asbestos management plan drafted in accordance with State and Federal regulations. 16)In addition to asbestos, the presence of lead based paints, PCB containing fluorescent light ballasts, and mercury containing fluorescent lamps should be evaluated prior to demolition of the structures on site. 17)A solvent washdown pad (in the vehicle maintenance area) was referred to in internal Spreckels documentation. Additionally, a truck washing area was identified between the factory and sugar warehouse by Mr. Tucker during our site reconnaissance. A historical "auto shed" was noted on site in Sanborn maps. The condition of soils at these locations should be further evaluated. 20-3978-01.W1012017L155 Page 12 of 50 Copyright 1997,Kleinfelder,Inc.
