Loading Conditions - Tank shall meet the following design <br />criteria: <br />1. Intemal load: primary and secondary tanks shall with- <br />stand 5 psi air pressure test with 5 to 1 safety factor. Con- <br />tractor shall individually test tanks prior to installation as <br />this is to test for leakage. Maximum test pressure is 5 psi. <br />2. Vacuum Test: Every tank shall be mercury vacuum tested <br />by the tank manufacturer to assure structural integrity. Pri- <br />mary tank shall be tested to 11.5 inches and secondary tank <br />tested to 9.5 inches mercury vacuum. <br />3. Surface Loads: Tank shall withstand surface H-20 axle <br />loads when properly installed according to current man- <br />ufacturer's installation instructions. <br />4. External hydrostatic pressure: Buried in ground with 7' of <br />overburden over the top of the tanks, the hole fully flooded <br />and a safety factor of 7:1 against general buckling. <br />5. Tanks shall support accessory equipment such as heating <br />coils, drop tubes, submersible pumps, ladders when in- <br />stalled according to tank manufacturer's recommenda- <br />tions and limitations. <br />B. Product Storage: <br />1. Tanks shall be capable of storing petroleum with specific <br />gravity up to 1.1. <br />2. The primary tank shall be vented to atmospheric pressure. <br />The tank is not designed as a pressure vessel. <br />3. Tanks shall be capable of storing gasoline or gasohol (10% <br />ethanol and 90% gasoline mixture), 90.5% gasoline and 9.5% <br />Oxinol-50" (4.75% methanol and 4.75% GTBA mixture); <br />Dupont EPA waiver (gasoline with 5% methanol and a mini- <br />mum of 2.5% cosolvent-the blend may contain a max- <br />imum concentration of up to 3.7 weight percent oxygen in <br />the final fuel); MTBE (methyl tertiary butyl ether) -gasoline <br />with up to 20%, by volume, of MTBE; jet fuel; av-gas; kero- <br />sene; diesel fuel; motor oil; or potable water at ambient under- <br />ground temperatures; or used for fuel oil at temperatures not <br />to exceed 150°F. <br />C. Materials: <br />1. Tanks (primary and secondary) shall be manufactured with <br />100% isophthalic polyester resin and glass fiber reinforce- <br />ment with no sand fillers. <br />D. Annular Space <br />1. Tank shall have a space between the primary and second- <br />ary shell walls to allow for the free flow and containment of <br />all leaked product from the primary tank. Space also allows <br />the insertion of a monitoring device through a monitoring <br />fitting. <br />E. Annular Space <br />1. Tank shall have a space between the primary and <br />secondary shell walls to allow for the free flow and con- <br />tainment of all leaked product from the primary tank. <br />Space also allows the insertion of a monitoring device <br />through a monitoring fitting. <br />Continued on reverse side.. .
