N.J. Stat. Ann. § 17:1C-36

4. Within 15 days after the date of mailing a statement of the assessment as provided in this act, a regulated entity may file its objections to its assessment with the commissioner. The filing of an objection shall not relieve a regulated entity from its obligation to pay its assessment in full within 30 days after receipt of the original statement of the assessment. Upon receiving those objections, the commissioner shall either: amend the statement as warranted, consistent with sections 5 and 6 of this act; or schedule and send a notice of a hearing on the objections, which hearing shall be held not less than 30 nor more than 60 days after the date of the notice.
