Ripon Unified School District <br /> Direction, Rate of Flow & Total Quantity of a Potential Discharge <br /> 40 CFR 112.7(b) <br /> Ripon Unified School District is located on private property and the main fuel tank is <br /> located south of the main building. The double wall concrete and steel fuel oil product tanks are <br /> designed with a containment system engineered to contain oil product fluids if the primary wall is <br /> compromised.No liquid discharge is expected to escape the containment's secondary wall. In the <br /> event of the failure of oil product storage tank's wall all of the contents may discharge into the <br /> concrete containment and appropriate mitigation measures would be employed. No liquid will <br /> escape the boundaries of the secondary containment wall. No spill or release will reach navigable <br /> water ways. <br /> With the exception of a failure of the secondary containment wall, the wall will hold the <br /> discharged volume of the #2 Diesel and Gasoline tanks within its boundaries and have the <br /> freeboard for precipitation. Spill kits are located at the fueling area to address any spill or discharge <br /> of oil products. <br /> Any discharge would be contained, controlled and the waste would be properly disposed <br /> of in a proper manner. All users of oil products are aware of the clean-up requirements and only <br /> employees of Ripon Unified School District have access to the oil products on site. <br /> Delivery drivers loading oil products into Ripon Unified School District's fuel tanks are <br /> trained to haul oil products. In the event of a discharge or spill the driver is trained and capable of <br /> controlling and mitigating the spill. Proper clean-up and disposal methods shall be employed and <br /> all waste shall be contained, labeled and removed as required. <br /> Although spills are not expected, Ripon Unified School District is committed to <br /> minimizing any impact from an oil product discharge. All discharges will remain on site and if a <br /> discharge occurs Ripon Unified School District will commit the resources, and if needed, contact <br /> one, or more, of their clean-up contractors to assist. All containment, clean-up and disposal will <br /> be managed by Ripon Unified School District's management to insure the proper handling of waste <br /> products. No spill or release is capable of reaching navigable water ways under the current <br /> operational systems used by Ripon Unified School District All potential discharges will remain <br /> within a controlled setting and will not be released beyond the boundaries of Ripon Unified School <br /> District's controls. <br /> Rate of discharge will vary from size of the discharge. With a release from a tank discharge <br /> rate 600 Gallons per minute. Discharge rate from the#2 Diesel and Gasoline delivery hose during <br /> refueling will be at 300 Gallons per minute. <br /> Fc <br /> 22 <br />
