made before or during the tightness test must be described in <br />the COMMENTS section. <br />Page 5 of 5 <br />Mast=Master. Siph=Siphon. PS=Piping Sump. Western FG=Western Fiberglass. <br />BP=Bottom Penetrations. <br />Note: Tank #2 Regular 87 Siphon, and Tank #3 Super 91 Tank Secondary Containment Sensor L3 <br />and Sensor L5 were in alarm when i arrived on site. I found both of the Tank Secondary <br />Containment Riser Caps loose. When i removed the sensors for testing, the alarms cleared. I <br />found 3/4" of water in both of the Tank Secondary Containments. I removed approximately 20 <br />ounces of water total from both of the Tank Secondary Containments prior to testing. The water <br />appeared dirty and sandy, and mirrored the back fill soil material around both of the Tank Secondary <br />Containment Risers. No smell of fuel present. I applied the Test Vacuum of -10" Hg. for one hour <br />on both of the Tank Secondary Containments, and no loss of Test Vacuum was detected throughout <br />the test periods. Possible source of water in both of the Tank Secondary Containments was surface <br />run off that entered the Tank Secondary Containment through the loose caps on both of the Tank <br />Secondary Containment Risers. After the Tank Secondary Containment testing was complete, i <br />placed the sensors back to their proper placement and no further alarms were detected. I applied <br />Pipe sealant compound to all of the Tank Secondary Containment riser threads to make a proper <br />seal. I instructed the Owner/Operator to log the alarms in the onsite alarm log with a description of <br />the alarm event. I advised the Owner/Operator to make sure these Secondary Containment Riser <br />Caps are secure after all testing events in the future to prevent surface water run off from entering <br />the Tank Secondary Containment. <br />9.
