SECTION 7. COST OF WASTEWATER COLLECTION AND TREATMENT AND CMOM SERVICES 7.1 Principles and Policies The Parties acknowledge that deterrnining rates based on costs is a wastewater industry practice and historically accepted practice of Fayetteville and its outside city customers. Principles, policies and methodologies to determine rates for wastewater collection and treatment and Capacity, Management, Operations and Maintenance services as described herein are intended to meet the objective of providing fair and equitable cost -based rates. The following general principles and policies are intended to provide guidance to formulating rate studies and associated documentation during the term of this contract and shall be utilized to the extent feasible in setting rates: 1. Adjusting rates upon abrupt changes in financial policies should be avoided. 2. Prepare rate formulations that are easy to administer and understand. - 17 - 3. Determine rates that are "fair and equitable" while balancing the needs of all Parties. 7.2 Framework for Determining Rates After taking into consideration the basic principles set forth above, retail wastewater treatment and collection system rates shall be developed by Fayetteville for Farmington customers based on the following framework: 1. Fayetteville and Farmington agree to collaborate on the criteria for rate adjustments to be utilized by an independent rate consultant to develop rates which are fair and equitable across all customer classes. 2. Utility rate studies require professional judgment. The Independent Consultants shall be instructed to use their professional judgment to develop a rate study that is fair and equitable and neither overly favorable nor burdensome to either Party. 3. The Independent Consultants shall possess a national reputation with demonstrable expertise in water and wastewater utility rate making and employ registered professional engineers and such other professionals as needed to develop the necessary criteria for rate making purposes to ensure that wastewater utility rates are fair and equitable across all customer classes computed on a cost of service basis. Fayetteville will incur the cost of the Independent Consultants. The Fayetteville Independent Consultant Selection Process shall include a Farmington representative designated by the Farmington Mayor. 4. The rate study analysis shall conform to generally accepted rate setting practices and be in compliance with the mutually agreed upon rate methodology based in whole or part on published rate making standards adopted and published by the -18- American Water Works Association (AWWA), Water Environment Federation (WEF) and other rate setting methodologies of authoritative organizations and practice manuals. 5. The cost of services rate calculation shall be a Utility Basis approach. It shall include all cost of service and the operations, maintenance and replacement cost for facilities which provide capacity enhancement or extend utilization of the existing capacity of Westside Treatment Plant and shall contain a rate of return allocation on the Net Plant required to provide service to Farmington customers. The rate of return percentage shall be computed by determining the average of interest rates for all outstanding Fayetteville water and sewer revenue bond issues at the time of each rate study and then adding to the average interest rate computation a premium of 1.5% to arrive at a total rate of return. The rate of return percentage provides compensation to the Fayetteville rate payers for Fayetteville's investment in the Fayetteville sewer collection system and treatment plants, and recognizes Fayetteville's ownership, risk and contributions. The determination of Net Plant shall exclude monies acquired and assets purchased with USEPA Grants or other forms of contributed capital, assets purchased utilizing loans supported in part or whole by USEPA Grants or other types of giants and assets purchased with a sales and use tax enacted by either Fayetteville or Farmington. 7.3 Rate Adjustments If the current wastewater rate study (estimated completion date in the second quarter of 2007) recommends a system -wide rate change prior to 2009, the rate may be adjusted accordingly in 2007 or 2008. Otherwise, the rate schedule established in Section 8 below is subject to adjustment by Fayetteville in 2009 and thereafter when Fayetteville rates are adjusted on a system -wide basis. Fayetteville agrees to provide Farmington a -19-
