Biological Opinion on the Replacement of the Unalaska Marine Center Dock Positions III and IV
and associated Proposed Issuance of an Incidental Harassment Authorization in Dutch Harbor, Unalaska, Alaska
This biological opinion considers the effects to ESA-listed species from the proposed issuance of an IHA and Corps permit authorizing the proposed replacement of the UMC Dock Positions III and IV. PR1 and the Corps determined that this project will have no effect on fin whales (Balaenoptera physalus), sperm whales (Physeter acrocephalus), blue whales (Balaenoptera musculus), North Pacific right whales (Eubalaena japonica), sei whales (Balaenoptera borealis), or Western North Pacific gray whales (Eschrichtius robustus). The Corps and NMFS PR1 determined that the project is likely to adversely affect the endangered Western North Pacific Distinct Population Segment humpback whale (Megaptera novaeangliae), the threatened Mexico DPS humpback whale (Megaptera novaeangliae), and the endangered western DPS Steller sea lion (Eumetopias jubatus). These action agencies further determined that the project may affect, but is not likely to adversely affect, designated critical habitat for Steller sea lions.
