incidental-take-authorization-servicepier-extension-project-naval-basekitsap-bangor which confirms that the applicant has implemented the required mitigation and monitoring, and which also shows that no impacts of a scale or nature not previously analyzed or authorized have occurred as a result of the activities conducted. The notice of
the proposed renewal IHA was published on July 19, 2021 86 FR

Description of the Specified Activities and Anticipated Impacts The Navy plans to continue its construction activities at Naval Base Kitsap Bangor. The remaining construction activities involve the installation of 103 18-inch square concrete fender piles by impact pile
driving over a 35-day period during a specified in-water work window July 16 through January 15 due to the presence of Endangered Species Act ESA-listed juvenile salmonids are likely to be present in the area FebruaryJuly; USACE, 2015.

The anticipated impacts, which include both Level A and Level B
harassment of marine mammals by impact pile driving, are identical to those analyzed and authorized in the initial 2018 IHA 83 FR 30406; June 28, 2018 and modified 2020 IHA 85 FR
