PERM 200-12 <br />5. If the spill bucket is found to have cracks, loose <br />parts or separation of the bucket from the fill <br />pipe, it is not considered to be liquid -tight. This <br />visually indicates a test failure. <br />NOTE: If the fill cap is not included in the <br />spill bucket test and/or the cap is not tight, it <br />could be the source of potential fuel contami- <br />nation from water intrusion. <br />NOTE: Before permanently plugging, ensure <br />that local regulations allow the drain valve to <br />be permanently plugged. <br />6.2.5 Test Procedure. <br />1. Add water to the spill bucket to a level within <br />1.5 inches of the top of the spill bucket. Allow <br />the water to settle for 5 minutes before the initial <br />water level measurement is taken. <br />2. Place the measuring stick vertically at the lowest <br />point in the spill bucket and extending above the <br />water level to allow for an accurate measure- <br />ment to be taken. The location of the measuring <br />stick must remain the same for each water level <br />measurement. Document the initial water level <br />measurement as measured from the bottom of <br />the spill bucket. Alternative measurement meth- <br />ods may be used provided that measurement to <br />1/16 (0.063) inch can be made. <br />3. Take all precautions to prevent the water level <br />from being disturbed during the duration of the <br />test. <br />4. After 1 hour, document the ending water level <br />measurement. <br />5. Upon completion of the test, remove and dis- <br />pose of the water according to Section 6.7, and <br />dry the inside of the spill bucket before returning <br />it to service. <br />6.2.6 Pass/Fail Criteria. If the water level has <br />dropped less than 1/8 (0.125) inch, the spill bucket <br />passes the integrity test. <br />If the water level has dropped 1/8 (0.125) inch or <br />greater, the spill bucket fails the integrity test. <br />
