Gentlemen :

Pursuant to our letter of February 12, 1965, regarding theuse of compacted fill for support of the prop.')sed L 40Xstorage tank, we have made studies of the possibility ofdifferential settlement in the till soils .

it is our understanding that the dead load of the tankstructure is a total of 200 , 000 pounds and the load of itscontents is 1,000 ,000 pounds , all of which will be supportedon a concrete footing which is continuous around the perimeterof the tank, and which has an inside diameter of 9-1/2 feetand an outside diameter of about 30 feet . The southerlyportion of the footing will be supported on bedrock or VcrfShallow fill . T1 northerly porti-.n of the rooting will besupported on compacted fill which 13 about 14 feet deep a tthe deepest point .

Dividing the total static load of the tan4 and 1t3 contentsbr the area of the footing, It :.as determined that the structureimposes a pressure on the soil on the or-JEr of 2,0X) pounds persquare foot , dl regarding the weight of the footing . Computa-tions for ultimate settlement zero made u3 ing this load andaszuming a I percent consolidation curve which i.s coffin forcompacted f1113 of a granular nature and assuming a aoi1 whichwelgna 125 "undo per cubic foots . These computations indicatethat footings supported on about 12 feet of cocted o11 may
