What to do if the statutory timeframe for the notifying the department is not met?

If the 1 business day time frame is not met, the person in charge should provide an explanation at the time of submission of the late notification/s, or as soon as possible thereafter, detailing the circumstances that led to this notification timeframe requirement not being met. The response should also include details on:
