Executive Order VR-202-A Healy Phase II EVR System Including Veeder-Root ISD Exhibit 2 System Specifications This exhibit contains the installation, maintenance and compliance standards and specifications that apply to the Healy Phase II EVR System Including Veeder-Root ISD installed in a gasoline dispensing facility. All components must be installed in accordance with the specifications in the ARB Approved Installation, Operation and Maintenance Manual for the Healy Phase II EVR System Including Veeder-Root ISD System. Nozzle 1. A vapor collection boot shall be installed on the nozzle at the base of the spout, as shown in Figure 213-1. 2. The Healy Model 900 nozzle has an integral vapor valve which prevents the loss of vapor from the underground storage tanks, ensures proper operation of the system and prevents the ingestion of air into the system. Any dispenser that has a nozzle installed that is determined to have a defective vapor valve, as described in items 3 or 4 below, shall be immediately removed from service (including nozzle(s) on both sides of dispenser) and a call for repair made immediately. 3. The maximum allowable leak rate for the nozzle vapor path, as determined by TP-201.26, shall not exceed the following: 0.038 cubic feet per minute (CFH) at a pressure of two inches water column (2.00" wc), and 0.10 CFH at a vacuum of one hundred inches water column (-100.00" wc) 4. Verification of the integrity of the vapor valve can be performed on installed nozzles using the nozzle bag test procedure in Exhibit 7. Vapor Collection 1. The WL 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.
