ASRC Marine Support, LLC's stated purpose is to ensure structural integrity of the Rig Tenders Dock during loading and unloading of moored vessels. The project site is located within Section 21, T. 7 N., R. 12 W., Seward Meridian; USGS Quad Map AK-Kenai C-4; Latitude 60.686823º N., Longitude 151.394527º W.; 55525 Rig Tenders Dock Road, Nikiski, Alaska. The applicant proposes to conduct maintenance dredging in order to remove up to 12,000 cubic yards (CY) of sand and gravel bottom substrate annually from a 2.9 acre area below the mean high water mark (MHWM, 19.7 feet above the mean lower low water mark of 0 feet elevation) of the Cook Inlet, a navigable water of the United States (U.S.). The dredging would be conducted using either a bulldozer, a crane, an end loader, or an excavator, and a truck. Material would be removed down to 10 feet below the mean lower low water mark. Dredging would occur at any time of the year. All dredging would occur while the tide is out and the area is dewatered. Dredged material may be temporarily stockpiled below the high tide line (HTL, 26.3 feet above mean lower low water elevation) during dredging activities; all stockpiled material would be removed from below the HTL before the area is inundated by the tide.
All dredged material would be temporarily stored in uplands and water from the dredged material would be allowed to percolate into the ground. No return water would enter the Cook Inlet. The dredged material would be used for routine construction and site maintenance on the upland portions of the property. No dredged material would be placed back below the high tide line or in other waters of the U.S..
All work would be performed in accordance with the enclosed plan (sheets 1-3), dated December 20, 2016. Please contact Katherine A. McCafferty at (907) 753-2692, by fax at (907) 420-0813 , or by email at
