Chapter 7: Inspection, Evaluation,and Testing_ <br /> Section 9 of the standard addresses leak testing methods. For shop-fabricated ASTs,the standard <br /> references the Steel Tank Institute Recommended Practice R912, "Installation Instructions for Shop Fabricated <br /> Stationary Aboveground Storage Tanks for Flammable, Combustible Liquids."The standard also references DOT <br /> regulations for portable containers: <br /> • 49 CFR part 173.28, Reuse, reconditioning, and remanufacturing of packaging, mainly for drums; <br /> • 49 CFR part 178—49 CFR Subpart 0,Testing and certification of intermediate bulk containers <br /> (IBCs); and <br /> • 49 CFR part 180.605, or equivalent,for portable container testing and recertification. <br /> Section 10 of the standard addresses the suitability for continued service based on the results of formal <br /> internal and/or external inspections performed by a certified inspector. For ASTs that show signs of damage <br /> caused by MIC,the criteria for assessing their suitability for continued service differ based on categories <br /> associated with the level of reduction of the shell thickness (as per Section 5 of STI SP001). For other tank <br /> damage, an engineer experienced in AST design or a tank manufacturer should determine if an inspection is <br /> required for any AST that was exposed to fire, natural disaster, excessive settlement, overpressure, or damage <br /> from cracking. <br /> Section 11 of the standard details recordkeeping requirements.Appendix A presents supplemental <br /> technical information including terms commonly associated with ASTs, and Appendix B presents information for <br /> the inspection of field-erected ASTs. <br /> For more information on STI SP001, please visit the Steel Tank Institute Web site, <br /> http://www.steeltank.com. <br /> 7.7.3 STI Standard SP031 - Standard for Repair of Shop Fabricated Aboveground Tanks for <br /> Storage of Combustible&Flammable Liquids <br /> STI Standard SP031 -Standard for Repair of Shop Fabricated Aboveground Tanks for Storage of <br /> Combustible & Flammable Liquid S156 covers the repair and modification of an atmospheric-type shop fabricated <br /> carbon and stainless steel tanks. It applies to tanks storing flammable and combustible liquids at atmospheric <br /> pressure with a specific gravity not greater than 1.0. STI SP031 is referenced in STI SP001 for repairs or <br /> alterations to an AST. <br /> 166 STI SP031 Standard for Repair of Shop Fabricated Aboveground Tanks for Storage of Combustible&Flammable Liquids 4th <br /> Edition November 2008,Revised November 2012 <br /> SPCC GUIDANCE FOR REGIONAL INSPECTORS 7-66 <br /> December 16, 2013 <br />
