Maintenance Drainage - Specific Conditions

(1)

General Conditions Apply. All the conditions set forth in OAR 141-093-0135 (General Conditions) apply to this GP.

(2)

Temporary Impacts Only. No conversion of wetland to upland is allowed. All material placed in wetlands must be spread in a thin layer before the onset of winter rains.

(3)

Removal of Woody Vegetation. Removal of woody vegetation must be limited to the minimum amount needed to complete the activity, including removal site access.

(4)

Maintenance of Riparian Buffer. Where practicable and necessary to complete the activity, removal of woody vegetation is limited to the north or east sides of the stream channel.

(5)

No Operation of Equipment in the Water Allowed. Equipment used to remove material must operate from top of bank position when feasible, otherwise from a dry position below top of bank.

(6)

Design to Limit Maintenance. To the extent practicable, the project must be implemented to naturally maintain inlet and outlet connections with the main stream channel.

(7)

Erosion Control. As necessary, erosion control measures must be installed and maintained during the activity and after disposal, so as to prevent discharge into waters of this state.
