PEI/RP1200-17 <br />APPENDIX A-1 <br />® CONTAIN 0ENS. HYDROSTATIC STAND PIPE TANKTEST CHECKLIST <br />Job Name: <br />Address: <br />City: <br />Record date / time when tank was last filled (wait 24 hours from last delivery) <br />Record today's date/ time <br />Record tank U. number (if known) <br />Product stored <br />Tank nominal capacity (gallons)* <br />Preparation: <br />1. Measure and record groundwater table level. <br />2. Fill reservoir riser pipe approximately 12" aver reservoir top. The level <br />in the riser pipe must be at least 12" higher than the groundwater table. <br />3. Diameter of reservoir riser pipe. <br />4. Inspect all exposed monitoring fitting plugs for leaks. <br />Begin test: <br />5. Record time (wait 3 hours after step #2). <br />6. Measure and record liquid level In reservoir riser pipe. <br />7A. Measure and record groundwater table level. <br />78. Record dispenser meter readings. <br />8. Record time (after steps #6 and #7, wait 4 hrs for 4,6;8'tank5 or 6 hrs for 10'dia. tanks). <br />9. Measure and record liquid level in reservoir riser pipe. <br />10A. Measure and record groundwater table level. <br />1013. Record dispenser meter reading. <br />End test: <br />Calculate changes: <br />11 A. Reservoir riser pipe level (step#6 minus step #9). <br />11 B. Groundwater level (step #7 minus step #10A). <br />11C. Dispensed product (step #7 minus step #106). <br />'fanb.-1 TinF:�2 <br />Results Interpretation -The calculated changes (lines 11 A,11 B, and 11 C) must meet all of the criteria in column "B' below to pass the <br />tightness test of .05 gallons per hour with a 95% probability of detection and a 5% probability of false alarm: <br />(A) (B) (C) <br />Criteria Tank passes test if... Tank test is inconclusive if... <br />Line #11 A Less than 1" More than I — <br />Line #11 B and less than 10" or more than 10—* <br />Line #11 C and less than 600 gallons or more than 600 gallons <br />You can use a tape measure and water/brine finding paste to determine accurate liquid <br />levels in site wells and the reservoir. <br />• Max tankdiameter 10; Max capacity 30,000 gallons <br />" Repeat test steps 6-11 <br />—To Improve test accuracy, discontinue dispensing, then repeat test steps 6-11 <br />Note: A 99.9% PD and 1.2% PFA tightness test without dispensing Is available by <br />contacting CSI Field Service <br />0 pei.org <br />Date <br />Technician's Name <br />333 North Rivershire Dr., Suite 190 - Conroe, TX 77304 • (936) 756-7731 • www.containmertsolutlonk.Com <br />Copyright ® 2017 Containment Solutions, Inc. • All Rights Reserved • January 2017 • Pub.
