Executive Order VR-101-D, Phil-Tite Phase I Vapor Recovery System, Exhibit 2, Page 2 an 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 demonstrating that the material is compatible for use with gasoline. One example of a typical vent pipe manifold is shown in Figure 2F. This shows only one typical configuration; other manifold configurations may be used. For example, a tee may be located in a different position, or fewer pipes may be connected, or more than one PN valve may be installed on the manifold. 4. The vent pipe manifold shall be installed at a height not less than 12 feet above the grade used for gasoline cargo tank delivery operations and shall conform to all applicable regulations. 5. Each PN valve shall have permanently affixed to it a yellow or gold-colored label with black lettering stating the following specifications: Positive pressure setting: 3.0± 0.5 inches H2O Negative pressure setting: -8.0± 2.0 inches H2O Positive Leakrate: 0.05 CFH at 2.0 inches H2O Negative Leakrate: 0.21 CFH at-4.0 inches H2O Rotatable Product and Vapor Recovery Adaptors 1. Rotatable product and vapor recovery adaptors shall be capable of at least 360-degree rotation and have an average static torque not to exceed 108 pound-inch (9 pound-foot). Compliance with this requirement shall be demonstrated in accordance with the latest adopted version of TP-201.1 B, Static Torque of Rotatable Phase 1 Adaptors. 2. The vapor adaptor poppet shall not leak when closed. Compliance with this requirement may be verified by the use of commercial liquid leak detection solution, 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.) Vapor Recovery and Product Adaptor Dust Caps Dust caps with intact gaskets shall be installed on all Phase I tank adaptors. Spill Container Drain Valve The spill container drain valve is configured to drain liquid directly into the drop tube and is isolated from the underground storage tank ullage space. The leak rate of the drain valve shall not exceed 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 the latest adopted version of either TP-201.1 C, Leak Rate of Drop Tube Overfill Prevention Device and Spill Container Drain Valve; or TP-201.1 D, Leak Rafe of Drop Tube/Drain Valve Assembly. Drop Tube Overfill Prevention Device 1. The Drop Tube Overfill Prevention Device (overfill device) is designed to restrict the flow of gasoline delivered to the underground storage when liquid levels exceed a specified
