Hoonah, Alaska: OK to Harass Sea Mammals for Dock

Published Date: 3/14/2025

Notice

Summary

The City of Hoonah in Alaska got the green light to do pile driving and removal for their new cargo dock from September 2025 to August 2026. This work might bother some local marine mammals, but the government says it won’t harm their populations or the people who rely on them. The project keeps marine life safe while helping Hoonah improve its waterfront.

Analyzed Economic Effects

3 provisions identified: 1 benefits, 2 costs, 0 mixed.

IHA Allows Hoonah Cargo Dock Work

NMFS issued an Incidental Harassment Authorization (IHA) to the City of Hoonah permitting pile driving and pile removal for the Hoonah Cargo Dock project from September 1, 2025 through August 31, 2026. Work is planned on approximately 107 days over a span of 5 months and includes installation of 542 steel sheet piles (330 linear feet / 100.6 m) plus multiple other steel piles (see project description).

Specific Authorized Marine Mammal Takes

NMFS explicitly authorizes incidental take (harassment) counts for specific marine mammals during the project: 11 Level B takes of minke whale; 214 Level B takes of humpback whale (estimated 210 Hawaii DPS, 4 Mexico DPS); 72 Level B takes of killer whale; 153 Level B takes of Pacific white-sided dolphin; 72 Level B and 12 Level A takes of Dall's porpoise; 321 Level B and 84 Level A takes of harbor porpoise; and 214 Level B takes of harbor seal (among other species listed). The authorization states no serious injury or mortality is anticipated or authorized.

Mandatory Shutdowns to Protect Marine Mammals

The authorization requires shutdowns and monitoring during pile driving: all construction work must be shut down prior to a humpback whale or other species entering the applicable Level A harassment zone for the activity underway. The document lists Level A harassment zone distances (for example, up to 2,831 m for some species and up to 4,381 m for others) and states Hoonah will be required to implement shutdowns during all pile driving activities.
