OAR 603-027-0397: Hydrocarbon Gas Vapor-Measuring Devices.

(1) As used in this rule, “Hydrocarbon Gas” means propane, propylene, butanes, butylenes and any other hydrocarbon gas/air mix maintained in a vapor state. (2) Method of Sale. Hydrocarbon gas shall be offered, exposed for sale, and sold by metered cubic foot or cubic meter of vapor defined as 1 cubic foot at 60°F or 1 cubic meter at 15°C determined from legal-for-trade hydrocarbon gas vapor-measuring devices as provided in ORS 618.121 and 618.141. Any charges or custody transfer of hydrocarbon gas shall be determined by a legal-for-trade, licensed hydrocarbon gas vapor-measuring device. (3) Retention of Customer Invoices. Any person engaging in the sale of hydrocarbon gas vapor shall retain a record of: (a) Each individual hydrocarbon gas vapor-measuring device billing invoice; and (b) The applicable rate schedule for a period of not less than 12 months and shall make them available at reasonable times for inspection and copying by the customer and the Measurement Standards Division. (4) Adjustment of Overcharges. Where, initiated by a written customer complaint and through a Measurement Standards Division certification examination, a hydrocarbon gas vapor-measuring device is found to be over-registering beyond the applicable tolerance, the person using the device shall issue a refund or credit to the customer for the amount of any overcharge, without interest, computed back to the date that the person using the device determines the hydrocarbon gas vapor-measuring device error commenced, except that the period of adjustment shall not exceed six (6) months. (5) Responsibility for Licensing. The person using hydrocarbon gas vapor-measuring devices is responsible to license these devices as required in ORS 618.121 prior to them being placed into commercial service. (6) Responsibility for Testing and Certification Examinations. The person using hydrocarbon gas vapor-measuring devices is responsible for: (a) Transporting and all associated transportation costs of hydrocarbon gas vapor-measuring devices to and from the Measurement Standards Division for testing and certification examinations; (b) Assuring that a minimum of 10 percent per year of all hydrocarbon gas vapor-measuring devices in commercial service as of July 1, 2002 are delivered to the Measurement Standards Division for testing and certification examination until all such devices have been tested and certified; and (c) Assuring that all hydrocarbon gas vapor-measuring devices are delivered to the Measurement Standards Division for testing and certification examination prior to them being placed into commercial service.
