N.J. Stat. § 26:2C-14.1
Any person aggrieved by an order of the department has 20 days from receipt of the order within which to deliver to the commissioner a written request for a hearing. Subsequent to the hearing, if requested, and upon a finding that a violation has occurred, the commissioner may issue a final order to cease the violation and assessing the amount of the fine specified in the order. If no hearing is requested, the order is a final order upon the expiration of the 20 day period. Payment of the penalty is due when a final order is issued or when the order becomes a final order. The authority to levy a civil administrative penalty is in addition to all other enforcement provisions in P.L. 1954, c. 212 (C. 26:2C-1 et seq.), and the payment of a civil administrative penalty does not affect the availability of any other enforcement provision in connection with the violation for which the penalty is levied. Pending the determination by the department and upon application therefor the department may stay the operation of such order upon such terms and conditions as it may deem proper.
