Fla. Admin. Code R. 25-7.054
(3) If a utility and consumer shall be unable to agree in regard to an extension, either party may appeal to the Commission for a review. The Commission, unless special circumstances prevent, will be guided by the following general principles:
(b) Extensions above free limit. When the cost of the extension required to provide service is greater than the free limit specified in paragraph (a) above, the utility may require a non-interest bearing advance in aid of construction of the cost in excess of such free limit provided that:
1. At the end of the first year the utility shall refund to the person paying the advance in aid of construction or his assigns an amount equal to the excess, if any, of the maximum allowable construction cost calculated using actual gas revenues, less the actual cost of gas, over the maximum allowable construction cost used to determine the amount of the advance in aid of construction.
2. For each additional customer taking service at any point on the extension within a period of five (5) years from date of construction, the utility shall refund to the person paying the advance in aid of construction or his assigns an amount by which the maximum allowable construction cost for the new customer exceeds the cost of connecting the customer, provided that an additional main extension shall have not been necessary to serve the additional customer.
3. The aggregate refund to any customer made through the provisions of subparagraphs 1. and 2. above shall at no time exceed the original advance in aid of construction of such customer.
4. The extension shall at all times be the property of the utility and any unrefunded portion of the advance in aid of construction at the end of five (5) years shall be credited to the plant account of the utility.
