VR-202-Z -2 Exhibit 2 Vapor Collection 1. The V/L ratio of the system shall be 1.05 plus or minus 0.10 (0.95 to 1.15), measured at a flow rate between six and ten gallons per minute (6.0 — 10.0 gpm). Any fueling point whose V/L ratio is determined to be at or below 0.80 shall be deemed defective and removed from service. The V/L ratio shall be determined by using the test procedure in Exhibit 5 with the shut-off port excluded, or with a CARB approved alternate test procedure. See Section 7 of Exhibit 5 for guidance on V/L adjustment. 2. Inoperative vapor pumps, as determined by the CARB Approved Installation, Operation and Maintenance Manual, constitute a defect. 3. For unihose dispensers, any modifications or repairs to the nozzle, hanging hardware or vacuum pump done to bring one fuel grade V/L into compliance at a fueling point invalidates the results of any previous fuel grade(s) tested before the alteration. All fuel grades at that fueling point shall be tested again to verify compliance. Inverted Coaxial Hoses 1. The maximum length of the hose assembly, including hose adaptor, whip hose, breakaway, flow limiter (optional) and inverted coaxial hose, measured from the base of the nozzle to the end of dispenser adapter or dispenser, as appropriate, shall be no more than eighteen (18) feet. 2. Any hose configuration is allowed. Breakaway Couplings Testing is required after reconnecting the breakaway to ensure proper operation and no observed leaks. The procedure for reconnecting breakaway and fueling point testing after a drive-off, referenced in Section 1.4 of Scheduled Maintenance, shall be conducted to verify that breakaway, hose and nozzle are operating properly after a drive-off. Flow Limiters Flow limiter is mandatory when the flow rate is greater than 10.0 gallons per minute to comply with U.S. EPA requirement.
