4. A manifold may be installed on the vent pipes to reduce the number of potential leak sources and PN valves installed. Vent pipe manifolds shall be constructed of steel pipe or an Drop Tube Overfill Prevention Device equivalent material that has been listed for use with gasoline. If a material other than steel is used,the GDF operator shall make available information demonstratmg that the material is 1. The Drop Tube Overfill Prevention Device(overfill device)is designed to restrict the flow of compatible for use with gasoline. One example of a typical vent pipe manifold is shown in gasoline delivered to the underground storage when liquid levels exceed a specified capacity. Figure 2G. This shows only one typical configuration:other manifold configurations may be The drop tube overfill device is not a required component of the vapor recovery system,but used. For example,a tee maybe located in a different position,or fewer pipes maybe may be installed as an optional component of the system. Other requirements may apply. connected,or more than one PN valve may be installed on the manifold. 2. The leak rate of the overfill device shall not exceed 0.17 CFH at 2.00 inches H2O when tested 5. Each PN valve shall have permanently affixed to it a yellow or gold-colored label with black as in accordance with TP-201.1D,Leak Rate of Drop Tube Overfill Prevention Device and lettering slating the following specifications: Spill Container Drain Valves(October 8,2003). Positive pressure setting:2.5 to 6.0 inches H2O 3. The discharge opening of the fill pipe must be entirely submerged when the liquid level Negative pressure setting:6.0 to 10.0 inches H2O is six inches above the bottom of the tank as shown in Figures 2A and 28. Positive Leakrete:0.05 CFH at 2.0 inches H2O Negative Leakrate:0.21 CFM at-4.0 inches H2O Threaded Riser Adaptor 6. Each FES PV-Zero PN valve installed shall have permanently affixed to it a label that The Threaded Riser Adaptor shall provide a machined surface on which a gasket can seal and identifies that it is compatible with E85. ensures that the seal is not compromised by an improperly cut or improperly finished riser. A Threaded Riser adaptor shall be installed on the following required connections. As an option,the Rotatable Product and Vapor Recovery Adaptors adaptor may be installed on other connections. 1. Rotatable product and vapor recovery adaptors shall be capable of at least 360-degree a. Product Spill Container(required) rotation and have an average static torque not to exceed 108 inch-pounds(9 foot-pounds). It. Vapor Recovery Spill Container(required) Compliance with this requirement shall be demonstrated in accordance with TP-201.113,Static c. Tank Gauging Components(required) Torque of Rotatable Phase I Adaptors(October 8,2003). 2. The vapor adaptor poppet shall not leak when closed. Compliance with this requirement shall Vapor Recovery Riser Offset be verified by the use of commercial liquid leak detection solution,or by bagging,when the 1. The vapor recovery tank riser may be offset from the tank connection to the vapor recovery vapor containment space of the underground storage tank is subjected to a non-zero gauge Spill Container provided that the maximum horizontal distance(offset distance)does not pressure.(Note:leak detector,solution will detect leaks only when positive gauge pressure exceed twenty(20)inches. One example of an offset is shown in Figure 2F. exists.) 2. A vapor recovery riser shall be offset up to 20 inches horizontal distance with use of Vapor Recovery,and Product Adaptor Dust Caps commercially available,four(4)inch steel pipe filings,a Phil-Tito Model M-6050 Vapor Riser Offset,or a combination of the two products, An example of a Phil-Tite Model M-6050 Oust caps with intact gaskets shall be installed on all Phase I tank adaptors. configuration is shown in Figure 2F. Spill Container Drain Valve Tank Gauge Port Components The spill container drain valve is configured to drain liquid directly into the drop tube and is isolated The tank gauge adaptor and cap are paired. Therefore,an adaptor manufactured by one company from the underground storage tank ullage space. The leak rate of the drain valve shall net exceed shall be used only with a cap manufactured by the same company. 0.17 CFH at 2.00 inches H2O. Depending on the presence of the drop tube overfill prevention device,compliance with this requirement shall be demonstrated in accordance with either Connections and Fittinas TP-201.1 C,Leak Rate of Drop Tube/Drain Valve Assembly(October 8,2003),or TP-201.1 D, Leak Rate of Drop Tube Overfill Prevention Device and Spill Container Drain Valve All connections and fittings not specifically certified with an allowable leak rate shall not leak.The (Ochrber 8,2003). absence of vapor leaks shall be verified with the use of commercial liquid leak detection solution (LDS),or by bagging,when the vapor containment space of the underground storage tank is subjected to a non-zero gauge pressure. (Note:leak detection solution will detect leaks only when positive gauge pressure exists).
