Dear Mr. Kolarich, This is in response to your September 3, 2020, application for a Department of the Army (DA) permit, to discharge up to 7 cubic yards of concrete into 0.0008-acre (34 square feet) below the Ordinary High Water Mark of Anan Creek in order to construct 12-inch thick walls inside an existing fish pass outlet control structure, and a 4-foot x 4-foot x 14-inch footing on bedrock inside a fish pass in support of the Anan Wildlife Observatory reconstruction project. It has been assigned file number POA-2020-00427, Anan Creek, which should be referred to in all future correspondence with this office. The project site is located at Latitude 56.183º N., Longitude 131.890º W.; on the Cleveland Peninsula, 35 air miles southeast of Wrangell, Alaska.

DA authorization is necessary because your project will involve placement of fill material into waters of the United States under our regulatory jurisdiction.

NWP No. 18 and its associated General Conditions can be accessed at: www.poa.usace.army.mil/Missions/Regulatory/Permits. You must comply with all terms and conditions associated with NWP No. 18.

Further, please note General Condition 30 requires that you submit a signed certification to us once any work and required mitigation are completed. Enclosed is the form for you to complete and return to our office.

Unless this NWP is modified or revoked, it expires on March 18, 2022. It is incumbent upon you to remain informed of the changes to the NWPs. Nothing in this letter excuses you from compliance with other Federal, State, or local statutes, ordinances, or regulations.
