Yes Yes Was sensor properly replaced and verified functional after testing? Yes Yes Comments— (include information on repairs made prior to testing, and reconirnended follow-up for failed tests) Sensor functionality was not confirmed.This procedure is not part of the Secondary Containment Testing scope of work. If the entire depth of the UDC is not tested,specify how much was tested, If the answer to any of the questions indicated with an asterisk M is"NO"or"NA',the entire UDC must be tested.
