VR-202-Z -5 Exhibit 2 Figure 2-5 or 2-5H shows a typical manifold configuration for three PN vent valves installed in parallel with the Clean Air Separator. Figure 2-6 or 2-6H shows a typical configuration for a PN vent valve mounted on a single 3" vent line with the Clean Air Separator. Figures 2-3, 2-4, 2-5 and 2-6 apply to vertical Clean Air Separator installations. Figures 2-31-1, 2-41-1, 2-51-1 and 2-61-1 apply to horizontal Clean Air Separator installations. Figures 2-7A, 2-8A, 2-9A and 2-10A show P/V configurations for the Permeator AT-150 installation options. Warranty Each manufacturer listed in Exhibit 1 shall include a warranty tag with the certified component(s). The manufacturer warranty tag, included with each component, shall be provided to the service station owner/operator at the time of installation. Vapor Recovery Piping Configurations NOTE: Vapor return piping shall meet the piping requirements specified in section 4.11 of CP-201. 1. Vapor Return and Vent Lines a. For facilities installed on or after April 1, 2003, all vapor return and vent lines shall be a minimum nominal internal diameter of 2 inches from the dispensers or the vent stacks to the first manifold. All lines after the first manifold and back to the underground storage tank shall have a minimum nominal internal diameter of 3 inches. Note: Facilities permitted by a local district prior to April 1, 2003 shall be required to meet the three inch diameter standard only upon facility modification which involves the addition, replacement, or removal of 50 percent or more of the buried vapor piping. After backfilling the vapor return and vent lines, the maximum pressure drop shall not exceed 0.5 inches WC at 60 cubic feet per hour as determined by TP-201.4, Dynamic Backpressure. The pressure drop shall be measured from the dispenser riser to the UST with pressure/vacuum vent valves installed and with the poppeted Phase I vapor connection open. b. For existing installations, the maximum pressure drop through the system shall not exceed 0.5 inches WC at 60 cubic feet per hour as determined by TP-201.4, Dynamic Backpressure. The pressure drop shall be measured from the dispenser riser to the UST with the pressure/vacuum vent valves installed and with the poppeted Phase I vapor connection open. Note: The V/L test from Exhibit 5 may be used to verify proper operation of the system, in lieu of measuring the pressure drop through the lines, provided that at least two gallons of product are introduced into the system through each dispenser riser, prior to the test.
