Spill Bucket Integrity Testing - Instructions <br /> General: Spill buckets for tank systems are neither intended nor designed for the storage of petroleum products, but <br /> rather to contain small leaks and spills for short periods of time.This section describes the procedures used to test <br /> the integrity of spill buckets to ensure that they do not leak. <br /> Warning: Do not use fuels such as gasoline, E85 or diesel as a test fluid because they present a serious fire and <br /> safety hazard. Gasoline vapors are flammable and can explode if exposed to an ignition source such as a spark or <br /> open flame. If a tank or containment area is not tight, using fuel as the test fluid will cause a release into the soil or <br /> groundwater. <br /> Purpose: This method is used to test the integrity of single-walled spill buckets or the primary containment of <br /> secondarily contained spill buckets. <br /> Description of test: The spill bucket is filled with water.The water level is measured at the beginning and end of the <br /> test. <br /> Test equipment: Test equipment shall include: <br /> •Water <br /> •Measuring stick that is accurate to within 1/16 (0.063) inch and of sufficient length <br /> •Stopwatch or other time-measurement device capable of measuring a one-second increment <br /> Preparation: <br /> 1. Care should be taken when conducting the test in the rain or during freezing weather conditions. <br /> 2. Remove and properly dispose of any liquid and debris(leaves, sediment and trash) in the spill bucket. Clean <br /> the spill bucket and examine it for damage,defects or improperly installed components. If there are loose <br /> components (e.g., loose band clamps or bolts), have them tightened before conducting the integrity test. If <br /> there are items that must be repaired or replaced (e.g., deteriorated gaskets/seals or drain valves), notify the <br /> owner/operator. <br /> 3. Examine the fill cap and adapter fitting for loose, missing or damaged parts, and have repaired if necessary. <br /> Have repairs made before putting water in the spill bucket. Make sure that the seal on the fill cap is present <br /> and in good condition.The cap must fit securely and be leaktight on the riser.The water level during the test <br /> typically will be above the cap, so a leaking cap will result in a failed test. As an alternative to a tight fill cap, <br /> use a plumber's plug in the fill riser if approved by the authority having jurisdiction (AHJ)and tank owner. <br /> 4. The spill-bucket drain valve, if present, must be leak-tight to pass the test. If it is not leaktight, it may be <br /> possible to simply remove and permanently plug the drain valve. <br /> 5. If the spill bucket is found to have cracks, loose parts or separation of the bucket from the fill pipe, it is not <br /> considered to be liquid-tight.This visually indicates a test failure. <br /> Note: If the fill cap is not included in the spill bucket test and the cap is not tight, it could be the source of <br /> potential fuel contamination from water intrusion. <br /> Test procedure: <br /> 1. Add water to the spill bucket to a level within 1.5 inches of the top of the spill bucket.Allow the water to <br /> settle for 5 minutes before the initial water level measurement is taken. <br /> 2. Place the measuring stick vertically at the lowest point in the spill bucket and extending above the water <br /> level in the spill bucket to allow for an accurate measurement to be taken.The location of the measuring <br /> stick must remain the same for each water level measurement. Document the initial water level measurement <br /> as measured from the bottom of the spill bucket.Alternative measurement methods may be used provided <br /> that measurement to 1/16(0.063)inch can be made. <br /> 3. Take all precautions to prevent the water level from being disturbed during the duration of the test. <br /> 4. After one hour, document the ending water level measurement. <br /> 5. Upon completion of the test, remove and properly dispose of the water. Dry the inside of the spill bucket <br /> before returning it to service. <br /> Pass/Fail criteria: If the water level has dropped less than 1/8(0.125) inch,the spill bucket passes the integrity test. If <br /> the water level has dropped 1/8(0.125) inch or greater,the spill bucket fails the integrity test. <br /> Proper disposal of test liquids: Test liquids must be disposed of properly. <br /> GPH=Gallons per hour,Y=Yes,N=No,NA=Not applicable,VPH=Vacuurn[Pressure/Hydrostatic,ID=Identification <br />
