The standards that facility personnel must use for inspecting and testing at a particular facility would be
<br /> specified in the SPCC Plan by the Plan preparer. If the PE requires the use of a specific standard for
<br /> implementation of the Plan,the owner or operator must also reference that standard in the Plan (67 FR 47057,
<br /> July 17, 2002).All actions (e.g., visual inspection or testing) performed by facility personnel must be
<br /> appropriately documented and maintained in permanent facility records as per§112.7(e). Note, however,that
<br /> certain industry standards may specify that an owner or operator maintain records for longer than three years,
<br /> in which case the owner or operator should keep comparison records of integrity inspections and tests as
<br /> directed in the standard in order to identify changing conditions of the oil storage container. Records of
<br /> inspections and tests kept under usual and customary business practices satisfy the recordkeeping
<br /> requirements.
<br /> In a case where the PE determines that industry inspection standards may not be appropriate in their
<br /> entirety for a facility's particular tanks and configuration,this section discusses the minimum recommended
<br /> elements for a hybrid inspection program.
<br /> 7.7.1 API Standard 653 —Tank Inspection, Repair,Alteration, and Reconstruction
<br /> API Standard 653—Tank Inspection, Repair,Alteration, and Reconstruction (API 6S3)152 provides the
<br /> minimum requirements for maintaining the integrity of carbon and alloy steel tanks built to API Standard 650
<br /> (Welded Steel Tanks for Oil Storage) and its predecessor,API 12C (Welded Oil Storage Tanks). API 653 may also
<br /> be used for any steel tank constructed to a tank specification.153
<br /> API 653 covers the maintenance, inspection, repair, alteration, relocation, and reconstruction of welded
<br /> or riveted, non-refrigerated, atmospheric pressure, aboveground,field-fabricated,vertical storage tanks after
<br /> they have been placed in service.The standard limits its scope to the tank foundation, bottom, shell, structure,
<br /> roof, attached appurtenances, and nozzles to the face of the first flange,first threaded joint, or first welded-end
<br /> connection.The standard is intended for use by those facilities that utilize engineering and inspection personnel
<br /> technically trained and experienced in tank design,fabrication, repair, construction, and inspection. Section 1 of
<br /> the standard introduces the standard and details its scope. Sections 2 and 3 of the standard list the works cited
<br /> and definitions used in the standard, respectively.
<br /> The standard requires that a tank evaluation be conducted when tank inspection results reveal a change
<br /> in a tank from its original physical condition. Sections 4 and 5 of the standard describe procedures for evaluating
<br /> an existing tank's suitability for continued operation or a change of service; for making decisions about repairs
<br /> or alterations; or when considering dismantling, relocating, or reconstructing an existing tank. Section 4 of the
<br /> standard details the procedures to follow in evaluating the roof,shell, bottom, and foundation of the tank.
<br /> Section 5 of the standard provides a decision tree to evaluate a tank's risk of brittle fracture.
