OAR 141-089-0695
Piling Placement And Removal Within ESH - 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)

Minimum Necessary. Number of pilings must be the minimum necessary to fulfill the essential purpose.

(2)

Sound Attenuation. A vibratory hammer must be used whenever feasible. If an impact hammer must be used to drive or proof steel piles, sound attenuation measures including cushion blocks (wood blocks between pile and hammer) and bubble curtains operated to distribute air bubbles around 100 percent of the piling for the full depth of the water column must be used:

(a)

If water velocity is 1.7 miles per hour or less, an unconfined bubble curtain may be used; or

(b)

If water velocity is greater than 1.7 miles per hour, a confined bubble curtain (e.g., bubble ring surrounded by fabric or metal sleeve) must be used.

(3)

Method for Removal of Piling. Removal of piling must be conducted using a vibratory method:

(a)

Piling must not intentionally be broken by twisting or bending;

(b)

Upon removal, piling must be handled to effectively contain all adhering sediment. All return flows must meet state water quality standards; and

(c)

Piling and containment materials must be disposed in an approved upland disposal site.

(4)

Removal Problems in Uncontaminated Sediment. If wood piling breaks above or below the bed surface within an area of uncontaminated sediment, piling must be cut at least three feet below the bed surface or otherwise pushed into that depth, then covered with a cap of clean substrate.

(5)

Removal Problems in Contaminated Sediment. If wood piling breaks above the bed surface within an area of known contaminated sediment, piling must be cut at the bed surface or otherwise pushed to that depth. If piling breaks in contaminated sediment below the bed surface, no further attempt at removal may be made and the hole must be covered with a cap of clean substrate.

(6)

Prevent Perching. Piling must be fitted with devices to effectively prevent perching by fish-eating bird species.

(7)

Barge or Top of Bank Position. Piling must be placed or removed from a barge-mounted or above top-of-bank position. If barge-mounted, barge must not at any time be grounded in the bed or banks.
