Minn. R. agency 167, ch. 7045, MANAGEMENT OF USED OIL, pt. 7045.0820
Wastewater, the discharge of which is subject to regulation under either section 307(b) or 402 of the Clean Water Act, including wastewaters at facilities which have eliminated the discharge of wastewaters, contaminated with de minimis quantities of used oil are not subject to the requirements of parts 7045.0790 to 7045.0990. For purposes of this part, "de minimis quantities of used oil" means unintentional, unavoidable small spills, leaks, or drippings from pumps, machinery, pipes, and other similar equipment during normal operations or small amounts of used oil lost to the wastewater treatment systems during washing or draining operations. This exception does not apply if the used oil is discarded intentionally or as a result of abnormal manufacturing operations resulting in substantial leaks, spills, or other releases, or to used oil recovered from wastewaters. Wastewater from which used oil has been removed to the extent possible is not subject to the requirements of parts 7045.0790 to 7045.0990.
