-7- <br /> 3. The dispenser shall be connected to the riser with either flexible or rigid material that is <br /> listed for use with gasoline. The dispenser-to-riser connection shall be installed so that <br /> any liquid in the lines will drain toward the storage tank. The internal diameter of the <br /> connector, including all fittings, shall not be less than one inch (1"). <br /> Note: The dispenser-to-riser connection is defined as the piping connection between the <br /> dispenser piping and the inlet of the dispenser riser. A vapor shear valve may <br /> also be part of the riser connection. <br /> 4. There is no length restriction for the vapor return piping of the system as long as the <br /> system complies with the maximum pressure drop requirement, item 1 of the Vapor <br /> Collection section. <br /> 5. No product shall be dispensed from any fueling point at a GDF installed with the Balance <br /> Phase li EVR System if there is a vapor line that is disconnected and open to the <br /> atmosphere. <br /> 6. Bulk Plant Operations are not allowed with this system. <br /> Dispensers <br /> 1. The dispenser vapor piping must be sized adequately to meet the maximum pressure <br /> drop requirement, item 1 of the Vapor Collection section. <br /> 2, Dispenser vapor piping shall be installed so that any liquid in the lines will drain toward <br /> the dispenser riser. <br /> Liquid Condensate Traps <br /> 1. Liquid condensate trap connections and fittings shall not leak. Compliance with this <br /> requirement shall be verified by the use of commercial liquid leak detection solution or by <br /> bagging, when the vapor containment space of the underground storage tanks is <br /> subjected to a non-zero pressure. (Note: Leak detection solution will detect leaks only <br /> when positive gauge pressure exists). <br /> 2. The Liquid Level Sensor shall alarm within five (5) minutes when tested in accordance <br /> with Exhibit 16, Liquid Condensate Trap Compliance Test. <br /> 3. The Liquid Level Sensor audible alarm shall be installed at a location that is most likely <br /> to be heard by the station attendant during normal station operation (e.g. cash register). <br /> 4. The Liquid Evacuation System shall automatically evacuate gasoline when tested in <br /> accordance with Exhibit 16, Liquid Condensate Trap Compliance Test. <br /> 5. A metal tag specifying the capacity of the Liquid Condensate Trap shall be installed and <br /> maintained as specified in the Installation, Operation, and Maintenance Manual. <br /> Balance Phase 11 EVR Systems Including ISD Systems, Exhibit 2 -VR-204-N <br />
