JUNEAU, Alaska – A massive cleanup effort is getting underway in Alaska, with tons of marine debris – some likely sent to sea by the 2011 tsunami in Japan – set to be airlifted from rocky beaches and taken by barge for recycling and disposal in the Pacific Northwest.
Hundreds of heavy-duty bags of debris, collected in 2013 and 2014 and stockpiled at a storage site in Kodiak, also will be shipped out. The barge is scheduled to arrive in Kodiak by Thursday before setting off on a roughly one-month venture.
The scope of the project, a year in the making, is virtually unheard of in Alaska. It was spurred, in part, by the mass of material that’s washed ashore – things like buoys, fishing lines, plastics and fuel drums – and the high cost of shuttling small boatloads of debris from remote sites to port, said Chris Pallister, president of the cleanup organization Gulf of Alaska Keeper, which is coordinating the effort.
The Anchorage landfill also began requiring that fishing nets and lines – common debris items – be chopped up, a task called impossible by Janna Stewart, state tsunami marine debris coordinator.
Pallister estimates the cost of the barge project at up to $1.3 million, with the state contributing $900,000 from its share of the $5 million that Japan provided for parts of the U.S. affected by tsunami debris. Crews in British Columbia will be able to add debris to the barge as it passes through, chipping in if they do. Pallister’s group has committed $100,000. Delays because of weather could drive up costs, which Pallister said is a concern. The cost to operate the barge is $17,000 a day, Stewart said.
Many of the project sites are remote and rugged. Crews working at sites like Kayak and Montague islands in Prince William Sound, for example, get there by boat and sleep onboard. The need to keep moving down the shoreline as cleanup progresses, and when combined with terrain littered with boulders and logs, makes it tough to set up a camp, Pallister said. There’s also the issue of bears.
While relatively few people visit these sites, it’s important to clean them, Stewart said. Foam disintegrates, which can seep into salmon streams or be ingested by birds, she said. There’s concern, too, with the impact of broken-down plastic on marine life.
What’s not picked up can get swept back out, she said.
“It’s like it never really goes away unless we get in there and actively remove it,” Stewart said.
Alaska has more coastline than any other state. And Alaska cleanup operations often are expensive and dangerous, said Nikolai Maximenko, a senior researcher at the Hawaii-based International Pacific Research Center.
“Even without the tsunami, Alaska is well-known for being polluted with all these buoys and other stuff from fisheries activity and from other human activities,” he said.
The logistics are complicated.
Dump trucks are expected to ferry the large, white bags of debris from the Kodiak storage yard to the barge after it arrives.
In other locations, the bags will be airlifted by helicopter to the barge, which Pallister expects will be “pretty maxed out” when the barge, roughly the size of a football field, is fully loaded.
Debris will be sorted for recycling in Seattle, with the remaining debris taken by train for disposal in Oregon, according to the state Department of Environmental Conservation.
