Overview of the Humboldt Bay Offshore Wind Heavy Lift Marine Terminal Project
What is actually being proposed, and how to make your voice heard!
Humboldt Waterkeeper has been studying the proposed Humboldt Bay Offshore Wind Heavy Lift Marine Terminal on the Samoa Peninsula for several years, with a focus on its potential impacts on Humboldt Bay — known to Wiyot people as Wigi — and the surrounding communities.

Understanding what is being proposed is the first step to understand the project's impacts. We developed this brief summary of the latest project description to help people think about how the project would impact the bay ecosystem, water quality, and people with various relationships with the bay. In the coming weeks, we'll be developing comments as we continue to research the impacts of the project components.




In 2020, 6PPD-quinone, the breakdown product of the tire preservative 6PPD, was identified as a major contributor to Urban Runoff Mortality Syndrome in the Puget Sound watershed, where adult Coho Salmon often die before spawning in areas with high concentrations of road runoff. Since then, studies have been done in San Francisco Bay, but little information is available beyond major metropolitan areas. This study is the first to examine concentrations of 6PPD-q in Humboldt County. Left: Alex Juan sampling Jolly Giant Creek in Arcata for 6PPD-quinone.
