City of Shageluk's stated purpose is the development of sanitation improvements in Shageluk, Alaska, including the modification of the existing lagoon. City of Shageluk proposes the placement of 11,000 cubic yards (cy) of clean fill material into a total of 3.952 acres of jurisdictional wetlands for the construction of a new sewage system. The new lagoon would place 20,000 cy of fill into 2.854 acres of wetlands, 3,000 cy of fill into 0.754 acre for the expansion of the existing lagoon for the creation of a percolation cell, mechanized land clearing of 0.197 acre to bury the tanks and outfall pipes, mechanized land clearing and placement of 1,500 cy of fill material within 0.055 acre to move the above ground pipes to below ground, and the placement of 3,000 cy in 0.09 acre for the construction of a temporary berm. The staging area would be located in a previously disturbed area and the quarry is in uplands.

POA-2014-432, Scott River

Expiration date: 4/28/2015

U.S. Forest Service’s stated purpose is to provide nearby and safe access to public lands accessed by Sand Trail, while improving critical salmon spawning habitat. Currently, there is no safe place to park vehicles and vehicles with off-highway vehicle trailers at the Sand Trail trailhead. The closest location to safely park these vehicles is 2.5 miles west from the trailhead, where both recreational and subsistence users are accessing public lands (at mile point 7 Copper River Highway). However, access to public lands at this area is restricted to subsistence users only, and the user created trails at this location cross and disturb critical salmon spawning and rearing habitat in the Ibeck Creek drainage. The U.S. Forest Service (USFS) proposes to discharge up to 6,700 cubic yards of clean gravel fill material into 0.68-acre of wetlands in order to create a driveway and parking area for the Sand Trail trailhead. All work would be performed in accordance with the enclosed plan (sheets 1-7), dated March 16, 2015. Please contact Shane McCoy at (907) 753-2715, toll free from within Alaska at (800) 478-2712, by fax at (907) 753-5567, or by email at shane.m.mccoy@usace.army.mil if further information is desired concerning this notice.

POA-2015-23, Gastineau Channel

Expiration date: 4/10/2015

Marine Exchange of Alaska’s stated purpose is to construct a three story office building for the Marine Exchange of Alaska with on-site access to the vessel M/V Cleat. Marine Exchange of Alaska requests authorization for the following work in waters and navigable waters of the United States (U.S.): 1. Demolish an existing treated timber retaining wall in 9 feet2 of waters of the U.S. below the mean high water (MHW) (+15.4 feet above the 0.0 foot contour line) of Gastineau Channel. Approximately 10 cubic yards of material would be excavated below the MHW temporarily impacting 102 square feet of substrate within the Corps jurisdiction. Additional excavation would occur above the MHW. The material would be stockpiled on uplands and reused as backfill for the excavated area to support the new retaining wall. 2. Install a new cast in place reinforced concrete retaining wall measuring approximately 49 feet long and 6 feet wide. Twenty-five feet of the proposed wall would be located a below the high tide line (HTL) (+20.8 feet above the 0.0 foot contour line) impacting approximately 137 square feet of intertidal substrate. 3. A total of (14) 24-inch diameter steel pipe piles would be installed below the MHW using a land based, crane mounted vibratory hammer. Final proofing using an impact hammer would ensure embedment. 4. A concrete slab measuring 2850 feet2 would be installed atop the pilings and retaining wall of which 983 feet2 would be seaward of the mean high water. Please contact Matthew Brody at (907) 790-4493, by email at Matthew.T.Brody@usace.army.mil, or by mail at the address listed above if further information is desired concerning this notice.

Expiration date: 4/22/2015

Harris Sand and Gravel, Inc's stated purpose is to load barges primarily with riprap and other gravel products at low tidal levels in support the Valdez Harbor Project. To relocate and discharge up to 296 cubic yards of native material into 1.14 acres of intertidal area in order to construct a barge dock that is usable at extreme low tides. Up to a 0.18-acre area would be dredged in order to obtain material to construct the barge dock. Therefore, the total impact area would be 1.32 acres. The barge dock would be up to 213 feet wide at the widest part (toe-to-toe) with 3:1 side slopes, and up to 288 feet long. No material would be brought from other sources to construct the barge dock. The barge dock front would have a bulkhead constructed of eleven (11) 14-inch diameter steel piles, supported by a 14-inch by 14-inch “I” beam on top, and up to four (4) concrete “tee” beams. The bulkhead would be further supported by being connected to two (2) log dead men embedded in the barge dock. Two dolphins each consisting of two (2) 14-inch diameter steel piles would be installed near the northern end of the barge dock. All piles would be driven to a maximum depth of -27 feet, and would be installed with a vibratory hammer. All work and fill would occur below the Mean High Water Line. The barge dock would be temporary with an anticipated lifespan of five (5) years, which is when the Valdez Harbor Project is projected to be complete. The barge dock and all supporting features would be removed at the end of this time. Site restoration is discussed in further detail in the “Additional Information” section of this Public Notice.
