OAR 603-095-2840: Required Prevention and Control Measures

(1) All landowners or operators conducting activities on agricultural lands are provided the following exemptions from the requirements of OAR 603-095-2840(2) to (5). A landowner or operator shall be responsible for water quality resulting from conditions caused by the management of the landowner or operator. Rules do not apply to conditions resulting from unusual weather events or other circumstances not within the reasonable control of the landowner or operator. Reasonable control of the landowner means that technically sound and economically feasible measures must be available to address conditions described in the Required Prevention and Control Measures. The Department may allow temporary exceptions when a specific integrated pest management plan is in place to deal with certain weed or pest problems. (2) Waste Management: No person subject to these rules shall violate any provision of ORS 468B.025 or 468B.050. (3) Upland Management and Soil Erosion: Landowners must prevent soil erosion to protect against sediment delivery to streams. (4) Streamside Management: Landowners must promote the establishment and development of adequate riparian vegetation for streambank stability, filtering sediment, and shading, consistent with site capability. (5) Irrigation Management: Irrigation must be done in a manner that limits the amount of pollutants in the runoff from the irrigated area or that leaches into groundwater.
