General secondary containment applies to on-site spills or leaks and is covered as follows: <br /> • Tank T1 and T2 fill ports are equipped with spill boxes to capture product leaks during hose <br /> connection and disconnection. The contents of the spill box can be manually pumped into the tank <br /> using the integrated hand pump above the box. <br /> • Spill kits stored at various locations around the Facility are shown on Figure 3. Contained oil <br /> products will typically be pumped or placed into a secure recovery drum or tanker truck and <br /> properly disposed of in accordance regulatory requirements. <br /> Specific (sized) secondary containment requirements are based on the type of containers, activities, or <br /> equipment in place at the Facility. The SPCC Rule specifies a required minimum volume for this type of <br /> secondary containment.Facility specific secondary containment includes: <br /> • 100 percent containment of the 10,000-gallon diesel tank (TI) is required. The tank is double <br /> walled providing full containment of the primary (inner) shell within the secondary (outer) shell. <br /> Containment space is not exposed to precipitation. <br /> • 100-percent containment of the 10,000-gallon gasoline tank (T2) is required. The tank is double <br /> walled providing full containment of the primary (inner) shell within the secondary (outer) shell. <br /> Containment space is not exposed to precipitation. <br /> �i� CONDOR <br />
