Ms. Joyce E. Casey U.S. Army Corps of Engineers PO Box 2946 Portland, OR 97208-2946

Re: Federal Consistency Concurrence for Maintenance Dredging at Oregon Coastal Projects

Dear Ms. Casey:

Thank you for your letter of May 1, 2014, requesting that the Department of Land Conservation and Development (DLCD) renew the federal consistency concurrence DLCD issued in 2004 for maintenance dredging at federal navigation projects along the Oregon Coast. The proposed action covers eleven dredging projects at ten sites along the Oregon coast:

• Tillamook Bay

• Depoe Bay

• Yaquina Bay

• Yaquina River

• Siuslaw River

• Umpqua River

• Coos Bay

• Coquille River

• Port Orford

• Rogue River

• Chetco River

The purpose of the ongoing maintenance dredging is to maintain the federally authorized channel depths and widths by periodically removing naturally occurring sediments. Dredging is accomplished by a variety of techniques, including hopper, clamshell, and pipeline dredges.

Dredged materials are disposed of in-water, at shoreline or beach nourishment sites, at upland disposal sites, and at designated ocean dredged material disposal sites.

The actions at all sites are a continuation of dredging and disposal actions that DLCD reviewed for consistency with the Oregon Coastal Management Program (OCMP) in 2004. On August 6, 2004, DLCD concurred that the maintenance dredging and disposal actions are consistent to the maximum extent practicable with the enforceable policies of the Oregon Coastal Management Program, contingent on the use of approved dredged material disposal sites and techniques. The 2004 concurrence requires compliance with any site-specific conditions for use of dredged

A10-1 material disposal sites contained in the applicable local, state, and federal regulations, including timing considerations, adaptive management techniques, and methods of disposal. The 2004 concurrence also incorporates conditions of the Department of Environmental Quality’s 2004 water quality certification.

Over the ten years since DLCD’s 2004 review, the Corps has received additional project information and has refined the project actions accordingly. These refinements, which the April 25, 2014 consistency determination outlines in further detail, include a more accurate quantification of annual dredged material volumes, a clearer understanding of certain site dimensions (and two newly designated ocean sites), a better understanding of the number of dredge barge loads required to move the dredged material to placement sites, and an extended in-water work period in certain areas.

DLCD agrees with the Corps’ determination that the project refinements do not result in substantially different coastal effects than those previously reviewed, and therefore the maintenance dredging program remains consistent to the maximum extent practicable with the OCMP. This concurrence is not time-limited, but rather is tied to the project’s effects on coastal uses and resources. Please notify DLCD if future changes to maintenance dredging and disposal activities at the eleven Oregon Coastal Projects will affect any coastal use or resource substantially different than originally described.

If you have any questions or comments regarding this finding or the consistency review process, please contact me at (503) 934-0029 or by e-mail at: juna.hickner@state.or.us.

Sincerely, /s/

Juna Hickner Coastal State-Federal Relations Coordinator

For this project, the disposal options include flowlane, beach nourislnnent, and upland disposal. The disposal options that will result in discharges of effluent to waters of the state include beach nourislunent and upland disposal.

A12-5

Water Quality Ce1tification Order No. 9765

Febmary 19, 2013

I. All dredge material from the side channels shall be tested for contaminant concentrations before dredging to help determine the appropriate disposal methods.

a. The sampling and analysis plan for each side channel shall be submitted to Ecology for review and approval no less than 90 days prior to a planned dredging event.

b. Testing results shall be provided to Ecology for review and approval prior to dredging.

C. Flow lane Disposal:

The following conditions apply to disposal of dredged material in the flowlane of the Columbia River:

1. Mixing Zone for disposal by hopper, bottom dump scow, or down spout: 900 feet downcurrent from the point of discharge and no more than !50 feet laterally from the vessel.

2. Disposal of material shall be conducted in a manner that prevents mounding of the disposed material.

3. Flowlane disposal by a hopper dredge or a bottom dump scow is approved provided the disposal sites are located:

a. waterward of the minus 20-foot contour, Columbia River Datum (CRD);

and,

b. to the greatest extent practicable, flowlane disposal sites shall be selected so that disposal material (i) disperses into or immediately adjacent to the mainstem navigational channel; (ii) is not likely to cause significantly increased shoaling in downstream side channels or to shoreline facilities such as docks, wharfs, vessel slips and marinas; and (iii) is not likely to cause a significant adverse alteration of bottom habitats critical to the life history of white sturgeon.

4. Ecology will consider the use of alternative methods for flowlane disposal, such as a flat-topped barge unloaded by a small emth mover. However, the use of an alternative disposal method shall require special review and approval by Ecology under this Order prior to usage.

5. Flowlane sites may be used for the disposal of sediments dredged by pipeline provided the dredged material is discharged through a downspout that is lowered at least 20 feet into the water column.

A12-6

Water Quality Ceiiification Order No. 9765 Pmiland District Corps of Engineers February 19, 2013

D. Shoreline Disposal by Pipeline Dredge:

The following conditions apply to pipeline dredging operations that involve the unconfined or partially confined disposal of dredged material on or immediately adjacent to the shoreline. Historically, this manner of disposal has been used primarily for erosion control, such as to protect property or structures, to nourish actively eroding beaches, and to fill fish stranding sites. Shoreline disposal may also be done to enhance, restore or create various riverine habitat features such as a spit or lagoon.

Beach nourishment is the most common shoreline disposal activity and is done by pumping a slurry of sand and water directly onto an actively eroding beach. The sand settles out on the beach while the turbid water or runoff flows back into the river.

1. Mixing Zone: 900 feet downcurrent from the discharge point.

2. Shoreline disposal operations, and particularly beach nourislm1ent, may result in the placement of dredged material waterward of the ordinary high water mark. In such cases, the disposal site shall be regraded to an approximate slope of 10 to 15 percent, with no swales.

3. Impacts to riparian vegetation at shoreline disposal sites shall be avoided or minimized whenever possible.

4. Erosion control measures shall be carried out to prevent the wind erosion of dredged material back into the channel.

E. Upland Disposal by Pipeline Dredge:

The following conditions apply to pipeline operations that pump dredged material to an upland site or confined disposal facility (CDF). Typically, a CDF consists of the following design features: [1] Earthen dikes that form the perimeter of the facility. [2] A weir structure that provides flow control and retention of the solid fraction of dredged material. [3] An outlet structure that conveys the turbid water fraction of dredged material [effluent] to a single point of discharge. The point of discharge may be a nearby surface water, wetland or bare ground.

1. Mixing Zone [for Single-point Effluent Discharge]: 300 feet downcurrent of the point of discharge.

2. CDF Design and Operation. The following "best management practices" pertain to the design and operation of a CDF:

a. The CDF should be designed to provide the maximum practical degree of solids retention during operation, and for the entire life of the site.

b. The outfall should be located so as to provide the maximum amount of

A12-7

February 19,2013 dilution or dispersion of the effluent and to minimize any potential scour or erosion effects to more sensitive aquatic resources such as small tributaries and sloughs, shallow tide flats, and wetlands.

c. To the greatest extent practicable, CDF sites shall be stabilized to prevent significant offsite erosion of the dredged material by either water or wind transport.

VI. Wetland and Wildlife Mitigation

A. The mitigation sites shall be developed as described in the Columbia River Channel Improvement Project Supplemental Evaluation, August 2008.

B. The Cottonwood Island mitigation site shall employ the specific construction and maintenance elements, as described in the Statement of Work- Columbia River Channel Improvement- Mitigation Cottonwood Island Riparian Restoration (Corps document number W9127N-09-C-0046).

C. The Woodland Bottoms- Chumbley mitigation site shall employ specific construction and maintenance elements, as described in the Statement of Work- Columbia River Channel Improvement- Mitigation- Woodland Bottoms, Chumbley Riparian Restoration (Cmps document number W9127N-09-C-0014).

D. The Corps shall monitor all mitigation sites for a period of 10 years after construction.
