Agenda Date: December 29, 1999 Item Number: 2G Docket: UW-991801 Company Name: Mirrormont Services, Inc. Staff: Jim Ward, Revenue Requirements Specialist Penny Hansen, Public Involvement Coordinator Recommendation: Approve the tariff revisions filed by Mirrormont Services, Inc., in Docket UW-991801, to become effective January 1, 2000. Discussion: On November 18, 1999, Mirrormont Services, Inc., (Mirrormont) filed for general rates in the amount of approximately $4,800 (2.5 percent) of additional revenue per year. The Company serves approximately 710 customers near Issaquah, in King County. The Company is completing its update to the Department of Health (DOH) required water system plan. This plan is revised every six years and is used to provide a uniform process for water utilities to identify present and future needs, address those needs and demonstrate operational, technical, managerial, and financial capability to achieve and maintain compliance with all relevant DOH quality and quantity regulations. Surcharge collections will be used for a loan repayment. The Commission did not receive any customer comments on this request. Mirrormont=s last general rate increase was July 1998. The average residential customer would see an increase of approximately $.50 per month ($6.00 annually.) The current and proposed rates are provided below: Monthly Rate Current Proposed Water System Plan Surcharge N/A $ .50 This surcharge will expire on January 1, 2006 or upon recovery of the loan principal ($18,000), plus interest and taxes, whichever occurs first. Any excess funds collected from growth will pay loan principal. The funds received from the surcharge will be deposited into a separate reserve account exclu-sively for the purpose of making loan payments for the water system plan. This separate reserve account will be listed on all Company financial records and will be considered a cash account asset (NARUC account #127). Expenditures from the reserve account will be treated as customer contri-butions for ratemaking purposes. Mirrormont will provide quarterly reports and bank statements for the period that the surcharge is in effect. Regulatory Services Staff has reviewed the information to support the filing and found the proposed rate to be fair, just, reasonable and sufficient. Therefore, Staff recommends that the Commission approve the tariff revision filed by Mirrormont Services, Inc., in Docket UW-991801 to become effective January 1, 2000.
