San Joaquin St. <br />Stocton, California 95201-2009 <br />Re: Flying J Travel Plaza, Ripon, CA. <br />• <br />Dear Mr. Kith: <br />Please allow this letter as part of the information required for the waist oil holding tank, as per our <br />telephone conversation you requested that I provide a statement confirming that the oil/water separator <br />and waist oil holding tank is an enclosed system. Following is a brief explanation of how the mentioned <br />system will operate as designed. <br />The system in question is designed to collect run off water from the fueling areas through a trench drain <br />system manufactured by Poly Drain, from the trench drain run off is diverted through a oil/water separator <br />consisting of stainless baffles, oil skimmer and "MPak" coalescing plate system manufactured by <br />Facet International. from the oil/water separator water is then discharged to the municipal storm sewer <br />system. The oil that is skimmed off the top of the water is gravity fed to the waist oil holding tank through <br />an enclosed pipe system. The entire system is self operating with the exception of scheduled pumping of <br />the waist oil tank and daily observations of the oil/water separator. As you can see the described system <br />is enclosed with the exception of an opening in the waist oil tank used only for pumping and observation, <br />and openings in the oil water separator for cleaning of the coalescing plates and observation. Also included <br />with the waist oil holding tank is the tank guard level alarm system previously submitted, and the <br />hydrostatic monitoring reservoir for continuous leak detection, submitted with this letter. <br />If you have any questions or if I can be of any assistance please don't hesitate to contact me (801)734-6507. <br />Best r ar <br />MeC rist <br />Wieser Architects <br />Project Manager <br />
