Council supports Alyeska’s appeal to EPA

In late 2020, Alyeska Pipeline Service Company appealed a July 2020 Environmental Protection Agency air quality rule that would regulate emissions from the crude oil storage tanks at the Valdez Marine Terminal.

Alyeska asserted that the new rule would not result in emissions reductions at the terminal, that local residents would not see air quality benefits, and that Alyeska was already controlling air pollution from the storage tanks using optimal methods.

Alyeska noted that the existing control system at the terminal captures 99.94% of all tank vapors, while the reduction goal for the updated rule is 95%.

The Council hired experts at John Beath Environmental to conduct an independent review of Alyeska’s appeal and their assertions, to determine if the Council should support Alyeska’s appeal or not.

The section of the standards being appealed establishes national emission limitations, operating limits, and work practices for major sources of hazardous air pollutants. Hazardous air pollutants can be harmful to human health and include carcinogenic compounds such as benzene, among nearly 200 other harmful compounds.

In addition to verifying Alyeska’s assertions, the review documented how the implementation of the new rule, as written by the EPA, would impact the amount of hazardous air pollutants coming from the terminal.

The Council’s independent review supports the key arguments in Alyeska’s appeal. The design of the existing vapor recovery system already controls vapors better than the alternatives required by the new rule. Imposing the entirety of the new rule at the terminal would not result in overall, local air quality benefits.

The Council will be supporting Alyeska in their appeal by sending a letter and the final report to the Environmental Protection Agency.

Prince William Sound is home to a variety of bird species in winter

Frigid Alaska winters can be a tough time and place for wildlife. Food is scarce, the climate can be extreme, and days are short. Many species of birds head south.

However, some hardier species, such as marbled murrelets, common murres, pelagic cormorants, black-legged kittiwakes, and glaucous-winged gulls tough it out over the winter.

Since 2007, Dr. Mary Anne Bishop, a research ecologist at the Prince William Sound Science Center, has surveyed the Sound in fall and winter to document these bird species. This work is done on behalf of Gulf Watch Alaska, an ecosystem monitoring program funded by the Exxon Valdez Oil Spill Trustee Council. The Trustee Council documents the recovery of wildlife species after the Exxon Valdez oil spill.

The Council recently worked with Dr. Bishop and Anne Schaefer, the Center’s avian research assistant, to expand the survey area. The Council needed to know if marine birds congregated in areas around the Valdez Marine Terminal and near the tanker lanes. If a spill were to occur, these are the most likely areas for oil to come ashore.

Quick protection if a spill happens

When creating oil spill contingency plans, it is important to know where critical habitats are located. Plans can be created ahead of time that will help responders act fast to protect these areas before they are damaged.

The researchers noted specific areas to safeguard including Port Etches and Zaikof Bay near Hinchinbrook Entrance, the head of Port Valdez between the Valdez container terminal and the Valdez Glacier stream, and in southeastern Port Fidalgo.

This was the first of three years proposed for this study. The report notes that it is difficult to draw conclusions from a single year, because composition and density of birds can vary during the overwintering, non-breeding season.

The results of the survey will be available through the Alaska Ocean Observing System.

How has subsistence harvest changed over time in the Exxon Valdez oil spill region?

This graphic image demonstrates how the number of different resources harvested by the average household decreased over time. In 2003, 21 different types of resources were harvested. In 2014, the average household harvested just 13 different types. Data compiled from five Alaska communities: Tatitlek, Cordova, Chenega, Port Graham, and Nanwalek.

A way of life that includes the harvest and use of wild resources for food, raw materials, and other traditional uses.

The Exxon Valdez oil spill changed the harvest and use of wild resources in Southcentral Alaska. Various anecdotal reasons such as concerns about oil contamination meant folks were hesitant to use these traditional resources.

The Council recently partnered with the Alaska Department of Fish and Game’s Division of Subsistence to study and document why and how the spill affected subsistence harvesting activities, both immediately after the spill and in the years since.

Fish and Game researchers analyzed data collected from the communities of Cordova, Chenega, Tatitlek, Port Graham, and Nanwalek from 1984 to 2014.

That data confirmed that harvesting decreased during the first few years after the spill, but numbers started recovering around two to three years after the spill. Overall, the rates increased steadily through the 1990s and into the 2000s. By 2014, however, two important facts became apparent.

Reduced diversity of harvested species

This graphic image demonstrates how the number of different resources harvested by the average household decreased over time. In 2003, 21 different types of resources were harvested. In 2014, the average household harvested just 13 different types. Data compiled from five Alaska communities: Tatitlek, Cordova, Chenega, Port Graham, and Nanwalek. Harvesters collect fewer types of resources than before the spill. Fortunately, the surveys tracked more than just numbers. Interviews with residents pointed to several causes, which changed over time.

While the drop immediately after the 1989 spill was mainly attributed to concerns about safety, this was less of a concern in more recent years. Among other causes, interviewees blamed overharvesting by both locals and hunters from outside the community.

A Nanwalek elder interviewed in 2014 noted that easy-to-access locations suffered the most. “Some people don’t have boats so they can’t go too far,” the elder told the surveyors. “They don’t even give ‘em a chance to get bigger.”

Fewer households harvesting more of the resources

Another discovery is that harvesting activities have become more concentrated. In later years, a smaller proportion of households harvested a relatively larger proportion of the resources.

For example, data for sockeye salmon harvests in Tatitlek shows that in 1987, the top 1/3 of the harvesters collected about 55% of the combined total. In 2014, the top 1/3 collected over 90%.

Sometimes those harvests are not shared with the community.

“The oil spill in one way was worse for subsistence and traditional community culture because it gave everyone money, and this gave them the ability for each individual to have their own boat motor,” noted an elder from Nanwalek in 2014. “Lots of people ended up doing subsistence only for themselves and overall, people shared [a lot] less together.”

How does this information help?

This project is helping the Council assess the potential long-term social consequences of the Exxon Valdez oil spill and other factors that may affect subsistence harvests in the spill-affected region. These effects are critical to document to help plan and be prepared in case of a future oil spill.
