Piping Secondary Containment: <br /> 1. Identify and document the secondary piping manufacture. <br /> 2. Reinstall and tighten test boots in piping sumps, turbine sumps, above ground <br /> terminations and under dispenser containment pans. <br /> 3. Apply pressure using an inert gas (nitrogen)to between 3 and 5 psi or as specified <br /> by the local Regulatory Agency. <br /> 4. Allow pressure to stabilize for approximately 10 minutes, record starting pressure <br /> and test time. <br /> 5. Run test a minimum of 60 minutes (1 hr), a passing line will have no loss of <br /> pressure. <br /> 6. Any loss of pressure is a failed test. If test fails: (A) Identify source of leak if <br /> possible. (B)Notify customer. Only limited minor repairs can be made on site <br /> during testing and must be approved prior to work being performed. (C) Reapply <br /> pressure to line if instructed. <br /> 7. Record final pressure, ending test time and any comments. <br /> 8. Maintain pressure on the lines during sump testing if applicable. <br /> Turbine, Piping, Fill& Dispenser Containment sumps: <br /> 1. Identify and document sump manufacture. <br /> 2. Remove leak monitor sensor. <br /> 3. Make visual inspection for loose, broken or defective fittings, seals or electrical. <br /> 4. Notify customer of any obvious failure points, make repairs only if authorized. <br /> 5. Remove any waste, fuel, sludge or other foreign material and dispose of in labeled <br /> 55 gallon DOT drum. <br /> 6. Fill sump with water to 1" above highest piping penetration or per Regulatory <br /> Agency approval. <br /> 7. Install Caldwell Systems "Level Change Indicator"or other approved test device. <br /> 8. Allow liquid to stabilize, document sump size and depth, start test and record <br /> time. <br /> 9. Run test for a minimum of 30 minutes, per manufactures specifications or <br /> Regulatory Agency approval. <br /> 10. Sump fails if a loss of 0.0025" is recorded. If sump fails. (A) Identify source of <br /> failure if possible. (B)Remove water to below point of failure. (C)Notify <br /> customer. Only limited minor repairs can be made on site during testing and must <br /> be approved prior to work being performed. (D) Repeat test if repair can be <br /> made. <br />
