Appendix B <br />(TYPE) AUTO LIMITER II Overfill Valve In Tank Shut Off Level Worksheet <br />Impsrtant_ This is meant to be a supplemental worksheet and not a substitute to following the installation <br />manual instructions. All length measurements are in inches. Please contact the Authority Having Jurisdiction <br />(AHJ) and review local, state, and national codes to determine the regulatory requirements governing shut-off <br />our re ion as well as take into account other considerations such as extreme tank tilt. <br />t'011442%, LY n y g , <br />Take the following measurements with the valve <br />Installed in the tank: <br />'Upper tube to shut off point on valve. <br />(D) = 48114 <br />(VII) = 130 314 <br />(U) = 127 5/8 <br />Top of tube flange to tank bottom. <br />(B) = 133 <br />i From the tank calibration chart provided by tank <br />manufacturer find the dipstick number (Y) which <br />corresponds to the 100% volume. <br />(Y) = 9.842 <br />1 1. To determine shut-off percentage: <br />E Subtract upper tube length (D) from distance to <br />tank bottom (B) <br />(X) = (B) — (D) - 2" _ (OPW) <br />A,(X) = (B) -- (D) = 84.75 (Other) <br />Using the tank calibration chart provided by the <br />tank manufacturer determine the tank capacity at <br />the calculated (X) dimension and the 100% volume <br />(Y) tank capacity. <br />F (X) tank capacity in gallons = _9,305 <br />(Y) tank capacity in gallons = _9.842 <br />SO% = (X) capacity/ (Y) capacity x 100 = 94.6% <br />FACILITY: (TANK 2 - REGULAR 1 - NORTH) <br />CHEVRON <br />.6633 PACIFIC AVENUE <br />STOCKTON, CA 95207 <br />NOTES: Valve was removed and functional. <br />It <br />i <br />(D) <br />Upper <br />f Tube J <br />W ; <br />Valve, �} <br />Length, <br />bottom of <br />cut <br />f <br />(B) <br />To Tank <br />(u) (Y) <br />valve Tank 1 <br />Length, Chart rl <br />top of cut r- 100% <br />Volume <br />Dipstick <br />v . <br />Note: The overfill valve must be installed per AHJ <br />requirements and all applicable local, state, and national <br />codes. If overfill valve is set above the allowable shut-off <br />percentage the overfill valve must be removed and <br />replaced. For reference 40 GFR part 280 Subpart B Section <br />280.20 overfill valves should be set to a maximum of 95%. <br />
