OAR 141-089-0715
Temporary Impacts to Non-Tidal Wetlands - Activity-Specific Conditions

Projects eligible for this GA must adhere to the general conditions in OAR 141-089-0650 (General Conditions) and the following activity-specific conditions:

(1)

Temporary Impact Rectification. Rectification of temporary impacts includes re-establishment of pre-existing contours and pre-existing vegetation.

(2)

Timing of Temporary Impact Rectification. Re-establishment of pre-construction contours and planting to re-vegetate temporarily disturbed areas must be completed within 24 months of the initial impacts. However, if the temporary impact requires only one construction season, site rectification must be completed within the same construction season as the temporary impact. Planting must include species of sufficient number, spacing, and diversity to replace affected aquatic functions.

(3)

Post-Construction Report Required. Within two years of planting, a report must be submitted to the Department. The report must include:

(a)

Data plots, according to OAR 141-090, to confirm that the wetland area impacted by the project meets wetland criteria; and

(b)

Photos taken at the previously established photo points.

(4)

Protection of Ground Surface. Before placing temporary fill in wetlands, fabric must be placed to allow complete removal of all temporary materials from the wetlands. If necessary to assist with removal of the fill, chain link fence or similar material may be placed under the fill. All fabric, fencing and other materials must be completely removed at project completion.

(5)

Stockpile Topsoil. When trenching, the upper 12 inches of topsoil must be removed and stockpiled separately from subsurface soils and used as the final layer in backfilling.

(6)

Prevent Hydraulic Piping. The project must be constructed to prevent underground hydraulic piping to dewater the site or adjacent wetlands. If the native underlying soils are not used as bedding material, and a coarser, non-native soil or other material is used, preventive measures must be used such as restoration of the restrictive layer and placement of clay or other impermeable plugs. Such plugs must be placed at each wetland boundary.
