All of the calculations are based on the <br /> site data that you have provided to us and on standard engineering values for the physical <br /> parameters,which you provided for the site. <br /> All of the calculations have been made In accordance with the protocols presented In the PEI <br /> manual RP-100/2000. These protocols present an analysis of underground tank buoyancy, <br /> which Is based on sound engineering practice. <br /> It Is the tank owner's responsibility to determine the suitability and applicability of Installation. <br /> Our sole responsibility In any Installation Is that presented In our standard warranty. <br /> Our calculations show that, given the installation parameters that you have provided to us <br /> (water table at mid-tank, standard Xerxes deadmen), the Buoyancy Safety Factors are as <br /> follows: <br /> sugyancy <br /> 8' 10Ia K D�II.................................................. ........ 5.25:1 <br /> 8', 15K DWT-II....... .......................... ........................ 5.02:1 <br /> Xerxes recommends a minimum Buoyancy Safety Factor of 1.20:1. I have Included copies of the <br /> worksheets for your files. <br /> If we can be of additional assistance, please feel free to contact us. <br /> Sincerely, eclticatlon, or <br /> r hereby WIN that this pian,sP <br /> report was Prepared by ma or under my direct <br /> Supervision and that I alawwss o1 m a d di the <br /> I e9r e <br /> Prote69ionet Eno P <br /> John Burwell, PE State of M John p.gunNelY <br /> weg f, Er;InerrfRg SwW= ate G:��Rag.No 24079 <br /> Attachments <br /> CORPORATE OFFICE/7901 XERXES AVENUE SOUTH,MINNEAPOLIS,MINNESOTASS431 <br /> PHONE(Q62)887-1890 FAX(982)887-1870 <br />
