Methods not testing the <br /> entire UDC should only be used if the monitoring system provides fail-safe turbine shutdown. (See SWRCB LG-160) <br /> a With the submersible pump running,place the sensor in product(discriminating sensors should also be placed in water). The time <br /> between placing the sensor in product and the turbine shutting down is the response time. This should be done if the secondary <br /> containment testing method used does not test the entire volume of the UDC <br /> This information is not needed if the entire UDC is tested. <br />
