CARB Executive Order VR-101-B Phil-Tite Phase I Vapor Recovery System for Gasoline <br /> Dispensing Facilities <br /> 13. Letter from Phil-Tite Enterprises dated 8/13/03 regarding their experiences using vacuum <br /> to test sump systems. <br /> Upon review of the materials and employment of these materials for water and vapor tight tank <br /> sump systems,it is my opinion and conclusion that sound engineering design and principles <br /> have been employed and that the Phil-Tite Water and Vapor Tight Sump System,when <br /> properly installed,will provide a water and vapor tight tank sump system. System can be <br /> integrity tested under vacuum. <br /> � z <br /> James H.Ray <br /> Sr.Civil Engineer <br /> offices Q?ia FESS10* <br /> BELLEVUE, WA 9f <br /> LA HABRA, CA Pb-24.518 <br /> MARTINEZ, CA <br /> PETALUMA, CA "tJ OWL <br /> t�F CAl1 <br /> RoSEVILLE, CA <br /> ScoTT'sDALE, AZ <br /> VANcouvER,WA <br /> www.rhldesign.com <br /> C:\CI V IL\3 rdPARTY\Ppile-Tite\PHILTTITEsumpsystean2.doc <br />
