CERTIFICATION BY UST SERVICE TECHNICIAN CONDUCTING THIS INSPECTION I hereby certify that the overfill prevention equipment was inspected in accordance with California Code of Regulations, title 23, division 3, chapter 16, section 2637.2 and all the information contained herein is accurate. UST Service Technician Signature If the facility has more components than this form accommodates, additional copies of this page may be attached. 21 Appendix B 71SO Overfill Valve in Tank Initial Shut off Level Worksheet Important: This is meant to be supplemental worksheet and not a substitute to following the installation manual instructions. All length measurements are in inches. Please contact the Authority Having Jurisdic- tion (AHJ) and review local, state, and national codes to determine the regulatory requirements governing shut-off capacity in your region, as well as take into account other considerations such as extreme tank tilt. Take the following measurements with the valve in- stalled in the tank: Distance from the 71SO inlet tube flange to the cast lug in the 71SO body (see figures), upper tube length. Note: the Upper Tube Length must be at least 16” to in- clude the protective bend in the tube. (D) = ______________________ Distance from the 71SO inlet tube flange to the top and bottom of lower tube, valve length. (W) = _____________ (U) = _____________ Distance from the 71SO inlet tube flange to the bottom of the tank.

If the overfill valve is set above the allowable shut-off percent- age the overfill valve must be removed and replaced. For reference 40 CFR part 280 Subpart B Section 280.20 overfill valves should be set to a maximum of 95%.

Using the proper methods when gauging your tank's contents will insure the most accurate reading and insure that you do not damage your tank. The following procedure should be followed whenever you use a gauge stick to determine the amountof product that is in your tank: 1) Use a wood dipstick with a rubber or nylon tip. Metallic dipsticks are not recommended. This will insure that frequent tank gaugings or an accidental dropping of the gauge stick into the tank will not damagethe tank bottom. 2) Slowly lower your gauge stick into the fill port until it touches the tank bottom. Never free drop the gauge stick. This can result in inaccurate measurements due to product splashing. Free dropping can also result in gauge stick damage and tank damage. 3) Remove your dipstickslowly and read the product level directly from the gauge stick. Water Paste Detection To detect water in the tank bottom, water detection paste is available from petroleum equipment distributors. However, some water detection paste cannot detect antifreeze mixtures. If antifreeze mixtures are used for the cavity monitoring fluid, the following product is capable of detecting water or antifreeze (brine or up to 50 percent glycol) solution in the tank water bottoms: WATER FINDER #7686-1870 DAYCO/NATIONAL DAYTON, OH TEL: 1-800-283-2926 FAX: 1-800-688-4854 Caution Pressurized deliveries are not recommended. If the delivery vehicle uses pumps to fill the tank, install overfill shutoff equipment in the tank and truck to prevent the tank from being overfilled. Overfillingthe tank under pressure will damage the tank even if the tank vent is unrestricted.
