OAR 632-010-0210: Disposal of Solid and Liquid Wastes

(1)(a) Permit stipulations by the Oregon Department of Environmental Quality regarding disposal of solid and liquid wastes generated by drilling, redrilling, deepening, or reworking operations are deemed to be a requirement of every permit issued under OAR 632-010-0010. (b) All wells used for disposal of solid and liquid wastes must be equipped with tubing and packers and be tested for mechanical integrity at least once every five years to determine that there are no leaks in the casing, tubing, or packers, and that there is no fluid movement into an underground source of water, other than that from which the fluid was produced, unless otherwise approved by the department. Acceptable tests include pressuring the tubing and casing annuli to demonstrate the integrity of the casing, tubing, and packers. Tracer surveys, noise logs, temperature logs, spinner surveys, or other methods approved by the department may be used to detect water movement adjacent to the wellbore. The department must be notified of all mechanical integrity tests, and the results submitted as required by OAR 632-010-0017. (2) Once field development is initiated, a separate permit is required from the Oregon Department of Environmental Quality for disposal of liquid and solid wastes.
