tank is fitted with a an 18 inch threaded manway with a 4-inch atmospheric vent on the primary tank,which is properly sized to this tank and the venting requirements as annotated for the design by Snyder Industries. 15. AST secondary containment(material/design/listed)_AST has secondary containment via single wall construction to completely capture product introduced into primary vessel. Secondary containment is via an impermeable steel berm,which has no openings other than the top,which was inspected,was tested,is intact and both AST and the berm are suitable for continued usage. Leak detection is visually ascertained via visual inspection of secondary containment area. Berm containment capacity is approximately 450 gals. 16. Damage to AST or systems. No damage reported by Owner/Operator. Upon inspection, no evidence of weld breaks, punctures,cracks,or other structural damage to the berm. Upon inspection,there was no evidence of cracks,breaks,punctures or other structural damage to the primary vessel. Leak detection is assured via inspections of the secondary containment. Poly thickness measured to 7.8 mm. average. Steel thickness of the berm was measured to.110 in. thickness,which would be in excess of steel thickness minimums under UL 142. 17.Comments Tank has a 1 '/4 in. closed fitting at base of tank. Tank had approximately 10 gals. of product at the time of the inspection. a. Dimensions of AST: Primary Vessel= 300 gallons capacity total Dimensions: Primary Tank: 38 in.Diam X 67 in.
