no signs of any corrosion, or of steel fatigue. The earthquake <br /> anchors are approximately 10 inch length, anchored into the <br /> concrete ad b 1-inch diameter anchors which are adequate to <br /> p Y q <br /> secure the support system, and would be standard for this type <br /> and age of installation. . The anchor bolts indicate no evidence17 <br /> ' <br /> of any defect or corrosion which would affect their ability to <br /> properly anchor. The support legs on each side of the Tank <br /> allows for the system to be raised at least 4 %2 inches and allows <br /> for easy and adequate inspection beneath the Tank. <br /> Shells/ Heads: <br /> The Aboveground Storage Tank has <br /> some minor nicks and flakes of paint <br /> along with very slight corrosion on the <br /> exterior shells of the Tank. There is no <br /> evidence of fracturing or impact <br /> I 993 <br /> .9,9,4;,y incidents, nor areas of corrosion wherein <br /> the steel has been substantially or even <br /> moderately impacted. As a result of the <br /> small amount of corrosion, and the ages <br /> of the Tank, it was determined that it <br /> would be appropriate to take steel <br /> thickness readings and measurements at <br /> multiple locations of the tank. As <br /> such, there were 20 steel thickness <br /> readings taken on each side of the tank, <br /> and 10 steel thickness readings taken on the ends of the tank. The results of the steel thickness <br /> of the outer shell of the Tank were very consistent. The Tank averaged 6.50 mm thickness, on <br /> �z <br /> RZ <br /> r, <br /> P I <br /> ..,^yam......�. <br /> ,..... .. r...,n....� '+1.5.,x. r .Y <br /> the sides which translates to .250 in. steel <br /> thickness average for that tank, and averaged 6.75mm thickness on the heads (ends), which <br /> translates to .266in. steel thickness average for the ends of the Aboveground Storage Tank. <br />
