Or. Admin. Code § 603-095-0740

Current through Register Vol. 63, No. 10, October 1, 2024

Section 603-095-0740 - Conditions

(1) All landowners or occupiers conducting activities on lands in agricultural use shall be in compliance with the following criteria. A landowner is responsible for only those conditions caused by agricultural activities conducted by the landowner. A landowner is not responsible for unacceptable conditions resulting from the actions of another landowner or occupier. Conditions resulting from unusual weather events or other exceptional circumstances are not the responsibility of the landowner.

(2) Unless otherwise noted, these rules are effective one year after adoption.

(3) Substantial amounts of sediment (i.e. in excess of water quality standards for sedimentation) moving from agricultural lands into waters of the state as a result of agricultural activities is identified as an unacceptable condition. Offstream ponds which do not contribute to the downstream system under normal weather conditions are exempt as they are often used to trap and contain sediment.

(4) Substantial amounts of phosphorous (i.e. in excess of water quality standards) moving from agricultural lands into waters of the state as a result of agricultural activities is identified as an unacceptable condition.

(5) Substantial amounts of bacteria (i.e. in excess of water quality standards) moving from agricultural lands into waters of the state as a result of agricultural activities is identified as an unacceptable condition. Off stream ponds which do not contribute to waters where public exposure is possible are exempt from this rule.

(6) Agricultural management or soil-disturbing activities that preclude establishment and development of adequate riparian vegetation for streambank stability and shading, consistent with site capability, along a perennial stream which has a site potential for such vegetation is considered an unacceptable condition. Minimal breaks in shade vegetation for essential management activities are considered appropriate.

(7) Irrigation practices that contribute significant amounts of warmed surface water (more than 3% of water pumped during any one irrigation setting to return as surface runoff to a stream) back into a stream are considered an unacceptable condition.

(8) Effective upon adoption, no person subject to these rules shall violate any provision of ORS 468B.025 or ORS 468B.050.
