My guess is that a failure to report is essentially be a regulatory violation, not a crime. Thus, a regulating agency will determine how to enforce. Which likely means they start with notices of violation and finally escalate to "reasonable" fines after repeated violations for normal cases. And finally the regulating agency/agencies may forward cases to the DOJ for civil lawsuits for extremely egregious violations.
