Executive Order VR-101-A, Emiibit 2, Page 2 Rotatable Product and Vapor Recovery Adaptors 1. Rotatable product and vapor recovery adaptors, designed to prevent loosening or over- tightening of the adaptor on the riser pipe shall be installed in accordance with the manufacturer's recommended installation. 2. Rotatable product and vapor recovery adaptors shall maintain a minimum 360-degree rotation and average static torque not to exceed 108 pound-inch (9 pound-foot) when tested as specified in Exhibit 5. 3. The vapor adaptor poppet shall not leak when closed. The absence of vapor leaks may be verified with 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 1. Dust caps shall be installed on all Phase I tank adaptors. Drop Tube and Drain Valve 1. The Drop Tube and Drain Valve (Drop Tube/Drain Valve Assembly) is designed to drain liquid directly into the drop tube and is therefore isolated from the underground storage tank ullage. The leak rate of the Drop Tube/Drain Valve Assembly shall be determined by using the test method specified in Exhibit 4.
