Comments— (include information on repairs made prior to testing and recommended follow-up forfailed tests) If the testing method does not test the entire depth of the UDC,specify how much of the UDC was tested. Methods not testing the entire UDC should only be used if the monitoring system provides fail-safe turbine shutdown. (See SWRCB LO-160) 'With the submersible pump running,place the sensor in product(discriminating sensors should also be placed in water). The time between placing the sensor in product and the turbine shutting down is the response time. This should be done if the secondary containment testing method used does not test the entire volume of the UDC This information is not needed if the entire UDC is tested.
