The following table summarizes the possible modes of failure, <br /> maximum quantities, rates of flow, and direction of flow for a spill in this area. <br /> Facility spill response procedures are closely followed as outlined in the <br /> Spill/Discharge Response Plan, Section 4.0. <br /> Mode of Failure Maximum Rate of Flow Direction of Flow <br /> Quantity <br /> Storage Tank Leak or 1,000 gallons Based on the largest Gradual to Contained within interstitial space of <br /> Failure tank size instantaneous double walled tank. <br />
