Comments— (include information on repairs made prior to testing, and recommended 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 sump is not tested,specify how much was tested. If the answer to Any of the questions indicated with an asterisk(*)is"NO"or"NA",the entire sump must be tested. (See SWRCB LG-160) ( T >j
