- 3 - <br /> 6. <br /> -6, The processor shall activate when the pressure Of the underground b <br /> e tank is less <br /> than 0,equal to 0A inches Wc (:50.4 inches WC) as determinedby Exhit 9. <br /> 7. The TLS-350 alarm shall activate when the emission factor is at or greater an 0.64 <br /> Pounds/1000 gallons dispensed over a 24 hour period. A visual and and blethalarm shall <br /> activate when this emission factor is exceeded for the first and second 24m <br /> periods, <br /> 8- The pressure reading from the TLS console shall be within ±0.2 inches <br /> measured ullage UST Pressure as determined by section 8 of Exhibit 8.WC of the <br /> 9. The TLS-350 audible alarm shall be installed at a location that is Most likely to be g <br /> ort <br /> Occupied by the station attendant during normal station operation (i.e., cash reiste <br /> r). <br /> 10. The TLS console controlling the membrane shall have an RS232 Pwhich shall be <br /> installed in a location that allows the R8232 Port to be easily accessible, and if appli <br /> Per district requirements, for use at anytime. A vacant R3232 serial Port shall alwaycable <br /> s be <br /> available to electronically download reports. <br /> Yeeder-Root Va orP <br /> The carbon type shall be BAX 61500 manufactured by MeadWestvaco. <br /> 2. Unless there is maintenance or testing being conducted on theprocessor, the vapor <br /> Polisher shall be on and in the automatic Vapor Processor mode and the inlet ball valve <br /> shall be locked in the open Position shown in Figure 2B-3 for normal Polisher operation. <br /> The handle of the ball valve shall not be removed. <br /> 3. The Pressure reading from the TLS console shall be within ±0.2 inches WC of the <br /> measured ullage UST pressure as determined by section 8 of Exhibit 8. <br /> 4. The Vapor Pressure Sensor shall be between +0.2 and—0.2 inches WC when tested in <br /> accordance with section 9 of Exhibit 8. <br /> 5. The Vapor Polisher leak rate difference between starting and ending Pressures shall be <br /> less than 0.5 inches WC loss when tested in accordance with Exhibit 11. The ending <br /> Pressure must be greater than 7.0 inches WC. <br /> Pressure drop across the Vapor Polisher <br /> at 18.0 standard cubic feet per hour flow shall be between 1.69 inches WC and 2.25 <br /> Inches WC when tested in accordance with Exhibit 11. Differences in temperature <br /> readings shall not exceed 10 OF when tested in accordance with Exhibit 11. The <br /> atmospheric pressure sensor reading shall be within 10% of the atmospheric pressure <br /> obtained from a local independent source when tested in accordance with Exhibit 11, <br /> 6. The hydrocarbon concentration from the vapor Polisher outlet shan not ex % <br /> volume iso-butane (9,000 PPMV or 50% of the lower explosive level (LEL))ceed when t0.9eby <br /> sted in <br /> accordance with Exhibit 12. <br /> VST Phase 11 EVR System, Exhibit 2 -VR-203-E <br />
