Oregon Administrative Rules
Chapter 860 - PUBLIC UTILITY COMMISSION
Division 37 - WASTEWATER SERVICE REGULATION FOR JOINT WATER/WASTEWATER UTILITIES
Section 860-037-0045 - Interest on Deposits for Residential and Nonresidential Service

(1) Each year, the Commission shall establish an annual interest rate that must be paid on customer deposits. The Commission will base the rate upon consideration of the effective interest rate for new issues of one-year Treasury Bills issued during the last week of October, the interest rate on the most recent issuance of one-year Treasury Bills, or the effective interest rate for the average yield of Treasury Bills of the closest term issued during the last week of October. This interest rate, rounded to the nearest one-half of one percent, shall apply to deposits held during January 1 through December 31 of the subsequent year. The Commission will advise water/wastewater utilities of the changes in the rate to be paid on customer deposits held as needed.

(2) Upon payment of a deposit, the water/wastewater utility shall provide the customer documentation showing the date, name of the customer or applicant, the service address, the amount of deposit, a statement that the deposit will accrue interest at the rate prescribed by the Commission, and an explanation of the conditions under which the deposit will be refunded.

(3) If the deposit is held beyond one year, accrued interest will be paid by a credit to the customer's account. If held less than one year, interest will be prorated. A water/wastewater utility shall keep a detailed record of each deposit received until the deposit is credited or refunded.
