Volumetric TTT Method TLS-250/250i/300/300i/300C/300PC/350/350PC/350R/350RPC UST Monitoring Systems <br />Version 8463. 8473. or 8493 Digital Sensing Probe (Magnetostrictive) <br />Limitations on the Results <br />The performance estimates above are only valid when: <br />• The method has not been substantially changed. <br />• The vendor's instructions for installing ad operating the method are followed. <br />• The tank contains a product identified on the method description form. <br />• The tank is no larger than 15.000 gallons. <br />*The tank is at least 95' percent full. <br />• The waiting time after adding any substantial amount of product to the tank is 8.25 hours. <br />• The temperature of the added product does not differ more than 8.57 degrees <br />Fahrenheit from that already in the tank. <br />• The total data collection time for the test is at least 3 hours. <br />• Large vapor pockets are identified and removed (for methods that overfill the tank). <br />• The method ( X ) can ( ) Gannet be used in the groundwater is above the tank. See other limitations <br />below.Z <br />9. Other limitations specified by the vendor of determined during testing: <br />ATG system. If the groundwater is above the bottom of the tank a non -tight tank may is detected by means of <br />continuous monitoring of the water level in the bottom of the tank by the ATG system <br />> Safety disclaimer: This test procedure only addresses the issue of the ATG system's ability to detect <br />leaks. It does not test the equipment for .safety hazards. <br />Certification of Results <br />I certify that the volumetric tank tightness testing method was operated according to the vendor's instructions. I <br />also certify that the evaluation was performed according to the standard EPA test procedure for volumetric tank <br />tightness testing methods and that the results presented above are those obtained during the evaluation. <br />J.
