The Code of Federal Regulations, 40 <br /> CFR 112, requires that the facility maintain a Spill Prevention, Control, and Countermeasures(SPCC) plan <br /> that adheres to the industry standard requirements for regular inspections. The Steel Tank Institute (STI) <br /> SP001 Standard requires that the aboveground storage tanks (ASTs) be formally inspected based on the <br /> category of the AST. <br /> Next Inspection Schedules <br /> STI SP001 recommends the interval to the next inspection be determined based on known tank category <br /> and volume.This 12,844 gallon tank is currently equipped with a spill control system in the form of a berm <br /> secondary containment.The tank has an inherent continuous release detection method (CRDM)in the form <br /> of a raised tank on saddle supports. The tank stores Dormant Oil and operates at ambient temperatures. <br /> Based on the current configuration, this tank is classified as a Category 2A tank. Per inspection interval <br /> definitions outlined in STI SP001, PEI recommends the following inspection schedules. <br /> Adhere to one of the following Inspection Options: <br /> Inspection Option 1 <br /> • Periodic Monthly and Annual AST inspections are to be conducted by owner's inspector. <br /> • An external, in-service inspection should be scheduled no more than 10 years from the current <br /> inspection date or sooner if a change in tank condition occurs. However, more stringent governing <br /> regulatory intervals of inspection may supersede this interval. <br /> • An Internal, Out-of-service Inspection should be scheduled no more than 20 years from the current <br /> inspection date or sooner if a change in tank condition occurs. However, more stringent governing <br /> regulatory intervals of inspection may supersede this interval. <br /> OR <br /> Inspection Option 2 <br /> • Periodic Monthly and Annual AST inspections are to be conducted by owner's inspector. <br /> • An external, in-service inspection should be scheduled no more than 5 years from the current <br /> inspection date or sooner if a change in tank condition occurs. However, more stringent governing <br /> regulatory intervals of inspection may supersede this interval. <br /> • A Leak Test as per SPI SP001 should be scheduled no more than 10 years from the current <br /> inspection date or sooner if a change in tank condition occurs. However, more stringent governing <br /> regulatory intervals of inspection may supersede this interval. <br /> sn.mrotEamw E�avaey neserazum,cnmmaew Ta•ayaweuw Page oaPA�e mate <br /> ®ID18PEL Ic <br />
