The pipes are attached to the tank for ease of avoiding spills when using the system and are therefore not considered more than a transport mechanism from the collection point. 2.2.2. Pump A pump [22CCR§66265.192(k)(2)(C&D)] is attached to the AST, to deliver waste oil to the AST. Facility approved waste transport technicians remove waste oil utilizing truck mounted hose and pump equipment for draining the AST. 2.3. STORAGE Vehicle waste oil [22CCR§66265.192(k)(8)] is stored within the AST. Waste oil specific gravity is approximated at 0.054 pounds per foot cubed (Ib/ft). The AST operating capacity is 1,000 gallons. 2.4. VISUAL INSPECTION A visual inspection [22CCR§66265.192(k)(9)] of the tank and its affiliated piping, ancillary equipment, interior surface and exterior surface, if present at the time of the inspection, did not reveal signs of leaks, corrosion, weld cracks or breaks or scrapes in coating which may cause a release from the tank system. There were no discrepancies noted at the time of the AST visual inspection. Figure 1 shows the top and north side views of the tank. A visual assessment summary is included as Table 3. 3.0. SECONDARY CONTAINMENT The waste tank is double walled and has a 100% secondary containment within the basement of the auto service bay for containment of a spill from the primary. The AST top and north side views are shown on Figure 1. 3.1. WASTE OIL TANK (AST) DESIGN The manufacturer of the AST was not identifiable by tank marking or Facility documents but is considered by industry standard as a bench top tank style. The primary compartments are typically manufactured [22CCR§66264.193(e)(3)] from A36 steel with
