n 17.1. GENERAL 17.1.1. Additional Xerxes tanks may be installed at existing locations if proper foundation support exists. 17.1.2. It is the responsibility of the tank owner to choose the correct method of installation. 17.1.3. Xerxes requires that one of the following methods be used. 17.2. PREFERRED METHOD 17.2.1. The preferred method (FIGURE 17-1) is: • Install a new tank in a separate hole at least 3 feet from the original hole. • Follow procedures outlined in this Installation Manual. • Exercise caution in keeping unusual surface loads off existing tanks. • Maintain the natural barrier of undisturbed soil between tanks FIGURE 17-1 17.3. ALTERNATE METHOD 17.3.1. If the preferred method outlined above is not practical, an alternate method (FIGURE 17-2) is: • Bury additional tanks in the same installation hole. • Empty existing tanks to less than 1/4 capacity. • Remove the surface slab. • Enlarge the excavation for the new tanks, leaving as much backfill as possible around existing tanks. • Install shoring, if necessary, to make sure that existing tanks do not move and sufficient backfill remains. • Follow procedures and requirements outlined in this Installa- tion Manual. • See SECTION 5 for excavation parameters. FIGURE 17-2 24 18.1. GENERAL 18.1.1. Owner must retain the Installation Manual and Operating Guidelines for future reference to operating guidelines. 18.1.2. In addition to these installation instructions and operating guidelines, follow all federal, state and local laws, regulations, codes and safety precautions that pertain to underground storage tanks and/or their associated systems. 18.1.3. Consult tank brochures, separate system instructions (such as oil/water separators) and separate accessory instructions, which are available upon request from the UST coordinator at the Xerxes plant nearest you. (See SECTION 20.) 18.1.4. Consult the applicable warranty for each tank for further operating guidelines and limitations. A copy of the warranty is available upon request from the UST coordinator at the Xerxes plant nearest you. (See SECTION 19.) 18.2. FILLING TANK 18.2.1. Never overfill the tank. 18.2.2. Xerxes recommends only gravity filling of tanks. AWARNING ares does not recommend pump or pressure filling of the tanks because an overfill or overpressurization could occur. Overfilling the tank while under pressure could cause tank failure even if the tank vent is unrestricted. Tank failure could result in death, sedous personal injury or property damage. 18.2.3. Each time the tank is filled, the owner/operator must make sure the tank is properly vented. (See SECTION 11.) 18.2.4.Owner/operator must determine whether the tank has overfill protection, such as automatic shut-off devices ("flapper valves") or vent -restriction devices ("ball -float valves"), which will close off the internal piping and reduce the tank's capacity. 18.2.5.Owner/operator must notify whoever fills the tank that it has overfill protection, which reduces the tank's capacity. 18.2.6. Before each tank filling, owner/operator or the delivery service must determine the tank's reduced capacity due to the overfill protection, and consult the instructions or guidelines provided by the installer and manufacturer of the overfill - protection device to determine how much additional product the tank can hold.
