In-Service AST Inspection Report <br /> Formal External Inspection of 8,800-Gallon Tank(AST-5) <br /> Valley Pacific Petroleum Services,Inc. <br /> Page 5 <br /> Requirements for Continued Tank Service <br /> The STI Standard for Inspection requires the owner or operator of an aboveground tank to perform and <br /> document periodic inspections. Refer to the checklists contained in the Facility's Spill Prevention,Control, <br /> and Countermeasures (SPCC) Plan. These documents should be completed by the owner or operator on a <br /> monthly and annual basis as part of the SPCC Plan. <br /> The following recommendations are based on the requirements of SP-001 and UL 142. These documents <br /> are industry standards. <br /> 1. The normal operating vents must be fully operational to prevent damage from overpressure or <br /> vacuum during product transfer. Normal vent covers were missing potentially allowing water <br /> (precipitation)to enter the tank compartments. Periodic inspection and maintenance of the normal <br /> vents by Facility personnel is recommended for proper vent operation. <br /> 2. The emergency vents must be fully operational and move freely to allow opening if overpressure <br /> occurs.Long bolts on the manway must not be bolted shut and should have a minimum of 2-inches <br /> of thread showing to allow the manway to open while under pressure. Periodic checks for proper <br /> emergency vent operation are recommended. <br /> 3. Leaks from the pump and piping system located at the northwest end of the tank should be repaired <br /> or equipment replaced in accordance with accepted good engineering practices. <br /> 4. Based on the STI Standard (SP-001), as a Category 1 tank, the interval until the next certified <br /> formal external inspection is 20 years.If the facility uses an alternate standard or chooses to provide <br /> "equivalent environmental protection"in lieu of routine integrity testing,the method and schedule <br /> for such should be included in the facility's SPCC Plan. <br /> a. If the Facility SPCC Plan requires the use of routine"integrity testing"using SP-001,then the <br /> following routine inspections should be completed by the Tank owner/operator. Specific <br /> inspection items may be modified for the tank's specific use as necessary;however,deviations <br /> from or alterations of the STI Standard should be discussed in the Facility SPCC Plan. <br /> 5. Effective September 2011, the STI Standard for Inspection requires the owner or operator of an <br /> aboveground tank to perform and document periodic inspections and maintenance. Refer to the <br /> checklists contained in Facility SPCC Plan. These documents should be completed by the owner <br /> or operator on a monthly and annual basis. <br /> Suitability for Continued Service <br /> Based on the STI criteria and results/recommendations of the current inspection,Condor formally approves <br /> continued use of the AST-5.A 20-year formal external inspection schedule,as a Category 1 tank,is required <br /> following the FEI date.Federal, state and/or local regulations may require more frequent inspections of the <br /> tank. <br /> 4.0 RECORD KEEPING <br /> 1.
