Starting from the beginning, the department is sorely in need of policies, procedures, leadership and training, both from a HMDA and LOS perspective.
Systems usually have timing reports - someone failed to use them. Like Nickel, there is a whole world of ECOA issues if timing requirements are not met - ECOA and Fair Lending. Identify each application that has not been funded. Eliminate the ones with adverse action letters, or notices of incompleteness. Withdrawn is a lousy term, because it means one thing to HMDA, and has a meaning of "I have no idea what happened, so find a home for it" to a loan officer.
Get legal involved. If there are a number that exceeded the 30 day period, management needs to be involved for guidance and preventive action for examiners. Compliance should not be holding the stick for the LO's. Then Train the ones that have not been fired.
