The department may recover any penalty assessment not paid under s. 49.471 (9) (c) from the employer against which the penalty was assessed. If, after notice that payment of a penalty is overdue, the employer who is liable fails to pay the penalty amount, or enter into or comply with an agreement for payment, the department may bring an action to enforce the liability or may issue an order to compel payment of the liability. The department shall issue the order to compel payment personally or by any type of mail service that requires a signature of acceptance from the recipient at the address of the employer who is liable for repayment as it appears on the records of the department. The refusal or failure to accept or receive the order to compel payment by the employer who is liable for repayment does not prevent the department from enforcing the order to compel repayment. Any person aggrieved by an order issued by the department under this paragraph may appeal the order as a contested case under ch. 227 by filing with the department a request for a hearing within 30 days after the date of the order. The only issue at the hearing shall be the determination by the department that the person has not paid the penalty or entered into, or complied with, an agreement for payment.
