Site Name, County, Operating Stockton, California, USA Date of Construction: 1938 Site Ref. No.: 31 Company: Total Site Area (m2), Freehold/leasehold/other: United Storage 8,900 Freehold Total Tanks Present & 32 Storage Volume (m3): 27,871 I113 Page 9 of 10 ISSUES FINDINGS IMPLICATION / CORRECTIVE ACTION Environmental Nuisances According to site management, no complaints have been made regarding noise or odour from the site. None Limited Compliance Overview The site holds a discharge consent for discharges to the POTW. Site operations appear to be in order. None PREVIOUS AUDITS / INVESTIGATIONS Details of relevant findings of last corporate SHE Audit Report not presented for review. None Date and relevant findings of last corporate engineering inspection Terminal Inspection Report, GR Reeves, 23rd January 2002 Spill trays are located along the rail siding such that all spillage's are collected and controlled — the area is maintained in good order. Two boiler-houses are located at the site — the older building housing a redundant boiler, which is due for removal. Arrangements are in hand to establish if the building or the boiler contains asbestos such that removal may be progressed in keeping with statutory requirements. The steam header from the redundant boiler remains pressurised under steaming conditions — arrangements are in hand for disconnection. A leaking steam pipe adjacent to the boiler hotwell requires attention. Mains water supply for process purposes is suitably protected as required by the water authority. Site drainage is via a gravity interceptor that is routed into the municipal sewer. A total of over 30 tanks and vessels provide for the storage and batch-mixing operation. No formal records of inspections or tank repairs are maintained. Spill containment is provided for only in the batch blending product area of the site, which includes acid storage. Any major spillage of product from the operation will almost certainly have a negative impact on the adjacent areas. Most of the site therefore drains to the municipal sewer through the main interceptor, which provides for a 3-chamber separator complete with isolation valve. A heavy spillage of oil in the bund area should be cleared. A single 16" NB MS dockline serves the facility — this is routed below ground for most of the route beyond the terminal. At the berth a section is , suspended below the warehouse. Inspection of the dockline below the berth and a formalised system of record keeping are recommended to establish and monitor the condition of the pipeline at the supports. A section of wrapping approx. 20' in length has been damaged at the berth immediately before the warehouse — this damage may have occurred during the installation of an adjacent pipeline. The dockline is extended to serve the adjacent Westway installation. The above ground section of pipeline should be prepared and None UCAEAS "LIERINC 916703113.doc
