New Jersey Statutes Title 40. Municipalities and Counties 40 § 37A-104

All facilities of a solid waste disposal system operated by a county improvement authority shall be open to use by any municipality or municipalities situate in the host county. Such facilities shall also be open to use by any municipality or municipalities situate in any county contiguous to the host county, provided that the population of said municipality, or the aggregate population of any several such municipalities, would not by itself or when added to the nonhost county population already using the improvement authority's facilities, be in excess of 10% of the total population of the host county. When the prospective nonhost county user population would exceed the foregoing 10% limit, the applications for use of the petitioning nonhost county municipalities shall require the prior approval of the governing bodies of the host county, and of any combination of municipalities situate therein, in accordance with the requirements and procedures set forth in section 5 of this amendatory and supplementary act.  1
