The marine net pen relocation project is driven by a US Navy proposal to build a pier on the harbor side of Ediz Hook that will expropriate a portion of the Aquatic Lands Lease area used by the existing AGS Port Angeles Harbor farm, and result in significant construction impacts and operational risks to the existing operation. This document includes a summary of the benthic, pelagic, and shoreline habitats in the vicinity of the proposed project area; a description of the threatened and endangered species and critical habitats that may be present in the project action area, and an effects analysis of the potential impacts of net pen construction and operation on the species and habitats most likely to occur within the project action area. Following the analysis of species and habitats of concern, Table E-1 provides the summary of effects findings for each species or group. Table E-1. Summary of effects analysis findings for protected and priority species that may occur within or near the project action area.
