Savannah, Georgia (AP) —A federal agency said Tuesday at the port of Savannah that a machine designed to inject extra oxygen for fish to breathe.

The Army Corps of Engineers released a 172 page report in last summer’s test that injection molding machines offset a small loss of dissolved oxygen in the water as the river deepened to make room for large cargo ships. I concluded that I was successful.

The Army Corps spends $ 100 million to inhale water, swirl with oxygen drawn from the air, and swirl the mixture with blue crabs, striped bass, and endangered short-nose surgeons.

A 2013 legal settlement with an environmental group that appealed for the deepening of the port required the Army Corps to prove that the machine worked.

Chris Descherer, a lawyer at the Southern Environmental Law Center who represented the group in a federal proceeding, said he had not yet reviewed the entire Army Corps report. He said he was concerned about the government’s commitment to long-term operation of the machine at an estimated cost of $ 3 million a year.

“We are skeptical about plans to use these machines permanently without a guaranteed source of funding to effectively solve this problem in most of these rivers,” DeScherer said. Said in an email statement.

DeScherer raised similar questions when the Army Corps previously reported the success of its first test in 2019. Still, environmental groups have chosen not to resume the legal battle over the project.

The South Carolina Department of Health and Environment, which is also a party to the 2013 legal settlement, did not immediately return an email asking for comment.

According to the Army Corps, a second round of testing found that the river’s two oxygen infusion stations delivered an average of 40,000 pounds of oxygen to the river daily from late July to late September. It concluded that oxygen was well mixed throughout the water column.

The injector operates each year in the hottest months of June-September, when river oxygen levels tend to be the lowest.

The agency says next year it should finish deepening the 27-mile (43-kilometer) shipping channel between the port of Savannah and the Atlantic Ocean.
