US land-based salmon farmer Whole Oceans received its final building permit Monday, clearing the way for the company to begin building it recirculating aquaculture system (RAS) facility, nearly two years after it first announced its plans to build a farm along the Penobscot River at the site of a defunct paper mill in Bucksport, Maine.

Although construction of buildings will likely not start until the spring, the permit is the last of nine local, state and federal approvals the project required," reports Maine Public Radio.

The farm is expected to begin operations in 2022 and begin selling fish two years later.

Construction of its 90,000-square-foot freshwater building is expected to begin in April, according to the permit application, and finish in October.

A second grow-out structure is scheduled to take 12 months starting in October, the radio station reported.
