N.J. Stat. § 13:9B-30
It is the intent of the Legislature that the program established by this act for the regulation of freshwater wetlands constitute the only program for this regulation in the State except to the extent that these areas are regulated consistent with the provisions of section 6 of this act. To this end no municipality, county, or political subdivision thereof, shall enact, subsequent to the effective date of this act, any law, ordinance, or rules or regulations regulating freshwater wetlands, and further, this act, on and subsequent to its effective date, shall supersede any law or ordinance regulating freshwater wetlands enacted prior to the effective date of this act. Between the enactment and effective date of this act, no municipality, county, or political subdivision thereof shall enact any law, ordinance, or rule and regulation requiring a transition area adjacent to a freshwater wetland; provided however, that any such law, ordinance, or rule and regulation adopted prior to the enactment of this act shall be valid until the effective date of this act.
