If a county, pursuant to agreement with a municipality or municipalities therein, joint meetings or authorities, shall construct or acquire solid waste disposal facilities which will benefit such municipality or municipalities, joint meetings or authorities, such county may either (1) bear the entire cost of the construction or acquisition of such facilities by itself, or (2) share the cost of the construction or acquisition of such improvements with the municipality or municipalities, joint meetings or authorities. The county may issue its bonds for all or part of the cost of the construction or acquisition of such facilities. If the cost thereof is to be shared by such municipality or municipalities, joint meetings or authorities, the county may issue its bonds for its share of such cost and such municipality or municipalities, joint meetings or authorities, may issue their bonds for their share of such cost, or the county may issue its bonds for all of the cost of such facilities, and the share of such cost to be borne by such municipality or municipalities, joint meetings or authorities shall be repaid to the county by such municipality or municipalities, joint meeting or authority in annual installments over a period not exceeding 40 years as shall be agreed upon between the county and such municipality or municipalities, joint meeting or authority. The amount of said annual installments shall include interest at such rate or rates as the county and such municipality or municipalities, joint meeting or authority shall agree upon, and the county and such municipality or municipalities, joint meeting or authority are hereby authorized to enter into agreements relating to such facilities which agreements shall have such terms and conditions as shall be deemed necessary and proper by such county and such participating municipality or municipalities, joint meeting or authority. Such agreements shall be authorized by a resolution duly adopted by the board of chosen freeholders of the county and by an ordinance duly adopted by the governing body of such municipality, municipalities, joint meeting or authority. Such annual payments received by a county from such municipality, municipalities, joint meeting or incinerator authority may also include an additional annual amount as shall be agreed upon for the payment of the agreed share of the cost of operation and maintenance and improvement or enlargement of such facilities.

Notwithstanding any provisions of any other law or laws now existing or hereafter enacted, the amount of any bonds issued by a county to finance the share of any municipality, municipalities, joint meeting or authority of the cost of the construction or acquisition of such facilities shall not be included in any computation of gross or net indebtedness under any such other law or laws as long as such county and such municipality, municipalities, joint meeting or authority have entered into an agreement pursuant to this section under which the share of such municipality, municipalities, joint meeting or authority shall be repaid to such county as provided in this section.
