  • Description:
    The action that is the subject of this revised consultation is NMFS Office of Protected Resources – Permits and Conservation Division’s (PR1) proposed issuance of an Incidental Harassment Authorization (IHA), under the MMPA, to take marine mammals by harassment (Level B), incidental to ExxonMobil Alaska LNG LLC’s (EMALL) proposed Geophysical and Geotechnical (G&G) Program, to be conducted in Cook Inlet, Alaska over 84 days, between August 14, 2015 and August 13, 2016. This document represents NMFS’s biological opinion (opinion) on the effects of this proposal on endangered Cook Inlet distinct population segment (DPS) beluga whale (Delphinapterus leucas). PR1 determined that the project is not likely to adversely affect designated Cook Inlet beluga critical habitat. PR1 also determined that the project is not likely to adversely affect the humpback whale (Megaptera novaeangliae) or the western DPS Steller sea lion (Eumetopias jubatus) due to their rarity and extremely low density in the project area. This opinion is also responsive to the U.S. Army Corps of Engineers (Corps) request for consultation on the authorization of this project under Nationwide Permits 5 and 6. The Corps has jurisdiction over the geotechnical aspects of the proposed G&G project, i.e., vibracoring, geotechnical borings, sediment grab samples, and Piezo-cone penetration testing.
