Executive Order VR-202-Z <br /> Assist Phase II EVR System <br /> Including In-Station Diagnostics (ISD) Systems <br /> Exhibit 2 <br /> SYSTEM SPECIFICATIONS <br /> SECTION I - EVR System Specifications <br /> This exhibit contains the installation, maintenance and compliance standards and <br /> specifications that apply to the Assist Phase II EVRSystem Including In-Station Diagnostics <br /> (ISD)Systems installed in a gasoline dispensing facility. All components must be installed, <br /> operated, and maintained in accordance with the specifications in the CARIB <br /> Approved Installation, Operation and Maintenance (IOM) Manual. Installation, <br /> maintenance, and repair of system components, including removal and installation of such <br /> components in the course of any required tests, shall be performed by technicians <br /> certified by the appropriate manufacturer unless otherwise specified in the IOM. <br /> Additional certifications may be required in accordance with local district requirements. <br /> Nozzle <br /> 1. A vapor collection boot shall be installed on the nozzle at the base of the spout, <br /> as shown in Figure 2-1. <br /> 2. The Healy Model 900 nozzle has an integral vapor valve which prevents the <br /> loss of vapor from the underground storage tanks, ensures proper operation of <br /> the system and prevents the ingestion of air into the system. Any dispenser that <br /> has a nozzle installed that is determined to have a defective vapor valve, as <br /> described in items 2.1 or 2.2 below, shall be immediately removed from service <br /> (including nozzle(s) on both sides of dispenser) and a call for repair made <br /> immediately. <br /> 2.1. The maximum allowable leak rate for the nozzle vapor path, as <br /> determined by TP-201 .213, shall not exceed the following: <br /> 0.038 cubic feet per hour (CFH) at a pressure of two inches water column <br /> (2.00" wc), and <br /> 0.10 CFH at a vacuum of one hundred inches water column (-100.00" wc) <br /> 2.2. Verification of the integrity of the vapor valve can be performed on <br /> installed nozzles using the nozzle bag test procedure in Exhibit 7. <br /> 3. Any nozzle that dispenses fuel with the miniboot in a free state condition, as <br /> determined by the quarterly inspection procedure, shall be removed from service <br /> until repaired or replaced. <br />
