14.0 Facility i w n <br /> 14.1 General Facility Drainage <br /> The KRC TRACY PLANT is situated on six acres south of the town of Tracy, CA (Figure 1, <br /> LOCATION MAP). The site is graded with a very gradual slope to the north east. Concrete <br /> paved areas occupy about 15 % of the area including a small lined washout detention basin <br /> under the plant conveyor belt with the balance covered in graded and compacted aggregate <br /> road base, Sand and aggregate stockpiles are in the central and western perimeter portions of <br /> the site. The regional slope is eastward towards the San Joaquin River. <br /> Storm flow and presumed worst case scenario with release when surrounding soil is saturated <br /> from precipitation would be expected to be intercepted by the facility adjacent storm water <br /> basin. Excess flow is directed to the outfall at the entrance gate. Any discharge of storm water <br /> would be performed in accordance with the requirements of the General Industrial Storm Water <br /> Permit. <br /> All storm drain drop inlets or drainage ditches in close proximity to the fuel AST flow to the <br /> surface containment (detention pond at the north corner of the site where a boom structure <br /> collects incidental floating oil products). <br /> 14.2 Drainage from Containment Areas <br /> Condensate that accumulates in the interstitial area of each tank is manually drained only if the <br /> water is first visually inspected to ensure that it is does not possess a visible sheen. If a visible <br /> sheen is observed, either the water will be transferred into drums and profiled for appropriate <br />'i disposal or sorbent material will be used to remove the oily sheen prior to discharge of the <br /> water. Interstitial volume openings to the atmosphere should be normally closed. Collected <br /> water in the interstitial area of either tank is considered to be out of the norm and should be <br /> immediately investigated for its source. <br /> The person conducting the drainage will document the event on the inspection log sheet <br /> (Appendix S). The log sheet will document the estimated volume removed, the time and date of <br /> the drainage, any observations regarding the presence and removal of an oil sheen, and the <br /> initials or signature of the person conducting the drainage. The drainage outlet will be resealed <br /> following release of accumulated wafter. The log sheet is maintained onsite in the KRC TRACY <br /> PLANT OFFICE. <br />:i <br /> 15 <br /> I <br />
