While they’re not exactly finalized, a Norwegian company’s plans for a proposed fish farm at the site of a former pulp mill are starting to take shape.“It takes about two years to build it,” said Marianne Naess, Nordic Aquafarms’ commercial director, at a meeting attended by a couple dozen people at the Wharfinger Building in Eureka on Tuesday night. Nordic Aquafarms is still going through the permitting process to build the $400 million on-land fish farm on the Samoa Peninsula, but Naess said she expects the company to complete that process this summer and start demolition of the old buildings within a year to a year-and-half. Construction will likely start in 2021 or 2022, meaning fish will be on the market around 2024 or so, Naess said.In terms of the soil and groundwater, Erik Nielsen, of SHN, said “they’re chipping away at the facility as things become available” because the buildings that remain are blocking their ability to check for dioxins and heavy metals, but so far the results are favorable.
