As per sheet F3 / # 98 the protective boot is <br /> described as a flexible jacket. This is not a containment area or chamber it is a protective envelope similar to <br /> the tape wrap around the galvanized riser pipe. This pipe system as per detail does not and should not <br /> contain fuel product, however if product should enter or accumulate in this system it will flow back into the <br /> tanks by gravitational force at 1/8" foot sloop back to the tank. To summarize we could remove this jacket, <br /> and have no corrosion protection as required by the CA Water Resources Board to comply with your request <br /> but it. If you have any questions regarding this issue please phone me at (707) 7651660 <br /> Yours sincerely, <br /> Ingmar Walter <br /> IF YOU DO NOT RECEIVE ALL PAGES INDICATED ABOVE,PLEASE CALL(707)765-1660 IMMEDIATELY. <br /> Fax; 707 765-9908 <br /> B E L L E V U E, WA LA H A H R A, CA MARTINEZ, CA P E T AL!IMA, CA <br /> S A C R AMENTO , CA SCO'I'T S D A L E, AZ VANCOUVER, WA <br /> F.\PROJECI\9k`9k.4\9720.40\DOCS1Dennis Catanyak vent riser.doc <br /> I -d OOZE 13CN3S1J-1 dH WdLZ : TT 2002 TO Had <br />
