In cases where extensions to the sewer system are constructed by a builder or developer at his own expense, or by a group of applicants at their own volition and expense, as outlined in the P.S.C. Rules and Regulations for the operation of sewer utilities, a refund of a portion of the sewer user charges paid by customers occupying dwellings served may be made to the builder, developer or other applicants under the terms of a refund agreement, entered into between the Governing Body and the builder, developer or other applicants. Such agreements will provide for refunds not exceeding such amounts and for such periods as may be authorized by the Governing Body. Each refund agreement shall be an individual agreement between the interested parties, and shall not be construed as outlining a definite procedure as to percentage of refund or the duration thereof. Each and every separate refund agreement shall be negotiated independently of any other existing similar agreement. In no event shall the terms of any refund agreement exceed ten years in duration.
