The ConVault System <br /> ConVault is an above ground, fuel and oil storage system manufactured for the purpose of above ground storage. The <br /> purpose of this testing procedure document is to aid ConVault owners and engineers in complying with the requirements <br /> of the Spill Prevention Control and Containment regulations for integrity testing or inspection as found at 40 CFR 112.3(c)(5) <br /> in efect as of January 14,2010. <br /> The ConVaulf system includes: <br /> 1. Primary containment: Inner shop fabricated steel tanks built in accordance with UI 142 Standard_The tank Is pressure <br /> tested for 24 to 48 hours after fabrication process, again pressure tested during the prerasting process, and also prior to <br /> shipment of the tank. <br /> 2.Secondary containment: Consists of a high density polyethylene (I IDPL) liner.[his secondary containment is vacuum <br /> tested prior to shipment of the tank. <br /> 3.Encasement inner steel tank and the HDPE liner are encased on all sides in 6"thick reinforced concrete.The entire system <br /> is elevated upon 4"to 6"high integral concrete legs. <br /> The Cbn'✓aultrbovegroundhielstorrgeryslerni5 manufactured and tested in accordarce with the 01.2085 Standurd <br /> t <br /> oi1 <br /> r <br /> 6 <br /> j <br /> ` 1.
