Answer- No,the standard applies to ASTs storing: <br /> •Stabl( nmable and combustible liquids at atmospheric f ,ure with a specific gravity less than <br /> approxin"rifely 1.0 <br /> •Liquids with operating temperatures between ambient temperature and 200 degrees F. <br /> Question#7:1 have a 25,000-gallon (94,607-liter)tank. Do 1 refer to STI SP001 or should I use API 653 as <br /> a basis for inspection? <br /> Answer:The scope of STI SP001 includes shop-fabricated and small field-erected tanks.The scope of API 653 <br /> includes tanks built to API 650 and API 12C.This leads to an overlap in the scope of the tanks covered by the <br /> standards.Therefore, more information is needed about a tank in order to decide the best inspection standard to <br /> use. <br /> For example, if it is a double-wall horizontal UL 142 tank,then STI SP001 probably is a better choice. If the tank <br /> has an API 650 nameplate and is located at a facility at which all of the other tanks are 500,000 gallons <br /> (1,892,150 liters)or more,then API 653 may be the better choice. Lastly,because of the risk-based inspection <br /> basis within the STI SP001 standard,the inspection schedule for many tanks is less conservative than API 653. <br /> Question#8: 1 have an insulated tank,and it will cost a lot of money and time to remove all of the <br /> insulation and then replace it.What must I do? <br /> Answer: Corrosion under insulation is a serious concern because the collection of water due to a gap in the <br /> moisture barrier may lead to a previously undetected problem. Paragraph 7.5 of the STI SP001 standard states, <br /> "Remove the insulation in areas where mold or moisture is present or points where moisture is likely to <br /> accumulate and examine the metal surface for signs of significant corrosion." <br /> Question#9:Who can inspect a tank per STI SP001 for me? <br /> Answer:There are two basic types of inspections included in STI SP001. Monthly, periodic inspections are to be <br /> performed by the tank owner's inspector and qualified per paragraph 4.1.2 of the standard. External and internal <br /> formal inspections are to be performed by a certified inspector.Certified inspectors may be either an API 653 <br /> certified tank inspector with an adjunct STI SP001 certification or an STI SP001 trained and certified tank system <br /> inspector.A list of STI AST inspectors is available here.The certification procedure for an API 653 inspectors may <br /> obtain an Adjunct STI SP001 Inspector certification through a web-based program.
