Executive Order G-70-164 Exhibit 2 Specifications for the Hasstech VCP-3A System Typical installations of the Hasstech system are shown in Figures 2A-1 through 2A-5. Nozzles 1. Failure mode testing has demonstrated that blockage of some of the vapor collection holes in the spout has negligible effect on the operation of the system. Any nozzle which has fewer unblocked holes than are required below is defective and shall be immediately removed from service. Total Number of Minimum Number of Unblocked Nozzle Tyw Holes per Nozzle Vapor Holes Regt ii red Emco Wheaton A4500 7 3 Husky V34 6200-8 8 1 (6 in circle around spout, plus (must be among the 6) 1 higher, and 1 for shutoff aspirator) OPW 11VAI 18 (steel spout) was not determined 12 (aluminum spout) was not determined 2. An Emco Wheaton A4500 nozzle (Figure 2C-2) which has any visible puncture or tear of the vapor guard/vapor seal assembly is defective and shall be immediately removed from service. 3. A leaking vapor valve, whether in the nozzle or remotely located, may compromise the vapor recovery capabilities of the entire vapor recovery system; therefore, it is imperative that defective vapor valves be corrected expeditiously in order to minimize emissions. The Husky V34 6200-8 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 nozzle with a defective vapor valve shall be immediately removed from service. The integrity of the system shall be restored by replacing the nozzle or otherwise closing the vapor path as soon as practicable. The OPW 11VAI nozzle (Figure 2C-1) and the Emco Wheaton A4500-002 nozzles do not have an integral vapor valve. These nozzles shall be installed with a certified remote vapor valve (i.e., CFC-1 flow control vapor valve) as specified in Exhibit 1 of this Order. Any nozzle associated with a defective remote vapor valve shall be immediately removed from service. The integrity of the system shall be restored by replacing the remote vapor valve or otherwise closing the vapor path as soon as practicable.
