Loading Conditions - Tank shall meetthe following design criteria: <br />1. Internal load: primary and secondary tanks shall withstand 5 psi air <br />pressure test with 5 to 1 safety factor. Contractor shall individually test <br />tanks prior to installation as this is to test for leakage. Maximum test <br />pressure is 5 psi. <br />2. Vacuum Test: Every tank shall be mercury vacuum tested by the tank <br />manufacturer to assure structural integrity. Primary tank shall be <br />tested to 11.5 inches and secondary tank tested to 9.5 inches mercury <br />vacuum. 1. <br />3. Surface Loads: Tank shall withstand surface H-20 axle loads when <br />properly installed according to current manufacturer's installation <br />instructions. <br />4. External hydrostatic pressure: Buried in ground with 7' of overburden <br />over the top of the tank, the hole fully flooded and a safety factor of 7:1 <br />against general buckling. <br />5. Tanks shall support accessory equipment such as heating coils, drop <br />tubes, submersible pumps, ladders when installed according to tank <br />manufacturer's recommendations and limitations. <br />B. Product Storage: <br />1. Tanks shall be capable of storing petroleum with specific gravity up <br />to 1.1. <br />2. The primarytank shall be vented to atmospheric pressure.
