N.J. Stat. § 40:66A-31
Any municipality may by ordinance require that by June 30, 1960 all trash and garbage collected within or without the municipality and disposed of within the municipality shall be disposed of by the sanitary landfill or incinerator method in accordance with the standards for the design, operation and maintenance of sanitary landfills and incinerators contained in the State Sanitary Code.
In the event that there is any inconsistency between such ordinance and the State Sanitary Code as to the time within which such methods of disposal shall be established, the ordinance shall prevail; provided, however, that no such ordinance shall take effect until it shall have been submitted to and approved by the State Commissioner of Health, who shall, in each case, make his determination on the basis of the extent of the need to establish such methods in the particular area affected.
