Seven major cruise lines face penalties for polluting the air while sailing Alaska waters.

The state Department of Environmental Conservation issued 18 notices of violation involving 48 instances of excessive air emissions since 2010.

Environmental Program Specialist Jason Olds says they were measured in Ketchikan, Juneau, Haines, Skagway and Anchorage. Others were spotted while sailing between ports.

He says government or contract monitors measured the density of ship smoke.

“The confusing way to say it might be that it’s the obfuscation of light. And the layman’s explanation is that we look at the contrasting background and how much of that is obscured by the plume.”

Details of the notices are not yet public because the alleged violations and penalties are being negotiated with cruise lines. Olds says they could be resolved within six months, though it could take longer.

He says the standard penalty is about $37,000 per incident.

Olds says violations were issued to almost all of the major cruise lines serving Alaska.

“We have Carnival, Holland America, Princess, Royal Caribbean, Norwegian, Celebrity and one to Silver Seas,” Olds says.

“All the ships are equipped with opacity monitors that actually measure the opacity as the smoke comes out of the stack,” John Binkley says. He heads up Alaska’s chapter of the Cruise Lines International Association.

He says the ships self-report when their monitors detect excessive emissions. But sometimes, that equipment comes up with different measurements than human observers.

“And so, that’s one thing they may be discussing in these alleged violations is, which do you give more weight to — the actual instrumentation or the person’s interpretation of what the smoke looks like?”

A number of cruise lines have installed or are in the process of installing stronger pollution-control equipment called scrubbers. They mostly target sulfur emissions, but also remove particulates that reduce opacity.

In addition to cruise ships, the ferry Columbia was found in violation while it was in Auke Bay, home to Juneau’s ferry terminal.

Alaska Marine Highway spokesman Jeremy Woodrow says that happened two winters ago, after new engines were installed.

“The department worked with DEC, tested the quality of the air coming out of the exhaust stacks and sure enough, it wasn’t in compliance,” Woodrow says.

Further adjustments were made and the Columbia met emission standards. Olds says his department took no further action.
