Drills and exercises getting back to normal

For the past few years, the COVID-19 pandemic affected many aspects of daily life. Oil spill drills and exercises were not exempt. Restrictions to protect the health and safety of responders limited these activities.

Not only were there fewer drills and exercises, they were harder to observe. Social distancing meant that Council staff could not board tugs and barges to see response operations up close. Council staff members Roy Robertson and Jeremy Robida, who have monitored drills and exercises in Prince William Sound for the past 18 and 13 years respectively, conducted some observations from a separate chartered vessel.

Fortunately, this year many of the restrictions were lifted.

New report summarizes 2022 drills

The Council’s annual report on drills and exercises conducted in Prince William Sound in 2022 has been released. The report highlights some of the continuing effects from the pandemic, along with a few changes that are here to stay.

Conducting business online

Virtual conferencing has changed many workplaces, including oil spill response. These technologies have shown up in several ways.

Coordinating online: Many drills are now hybrid (in person with online participants). Meetings are broadcast on videoconferencing platforms. Documents and other data are shared through online collaboration tools. Robertson says there are still some glitches, but these are improving.

Live video streaming: During a drill in May, the Alaska Department of Environmental Conservation deployed a drone over some activities out on the water. They were able to stream live video to the Valdez command center and participants in Jacksonville, Florida. The video was also recorded and available for later review.

Online training options: Alyeska’s Ship Escort Response Vessel System conducts annual trainings for crews of local fishing vessels, who are contracted to respond in case of a spill. Before the pandemic, part of the training sessions were held in a classroom, part were hands-on experience with equipment on dry land, and finally, crews would practice deploying equipment on the water.

Since the pandemic, the classroom sessions have been held online. The dry-land portion that required closer physical interaction between participants had not been held since 2020, but returned in 2023. The on-water portion remains the same.

Improvements at Valdez Duck Flats

Pandemic restrictions particularly affected exercises to practice either diverting oil from shorelines or protecting locations that are particularly sensitive to oil contamination, such as hatcheries. These tactics are performed by fishing vessels which have little room for social distancing. The return to in-person exercises is important for these activities.
Robertson noted in the report that responders spent more time this year practicing tactics to protect the Valdez Duck Flats, a highly productive biological area that provides critical habitat for a variety of waterfowl, small mammals, and marine mammals. This area is particularly sensitive to oil contamination. This was time well spent, he says. Robertson said that the responders have become more proficient at these tactics.

Cleaning up a big oil spill

A large spill would require equipment brought in from other regions. The Council recently sponsored a study on the availability of equipment on short notice.

The oil industry in Prince William Sound has one of the best-equipped spill prevention and response systems in the world. However, if a big spill were to occur, more equipment would still be needed.

Council updates position on dispersant use during an oil spill

Prevention and mechanical recovery should remain primary options

The Council’s Board of Directors has updated the organization’s position on use of chemical dispersants in the event of an oil spill in the Prince William Sound and the Exxon Valdez oil spill region. The updated position states that dispersants should not be used on Alaska North Slope crude oil spills in the waters of our region.

Chemical dispersants are substances applied to floating oil slicks that break the oil into smaller droplets that disperse into the water column.

The Council has long endorsed mechanical recovery as the primary tool to clean up an oil spill. Unlike dispersant use, mechanical recovery with booms and skimmers removes oil from the water. Conditions in Prince William Sound often limit the feasibility of dispersant application and dispersants have not been demonstrated to be effective in marine environments with similar temperatures and salinity levels to those found in the Sound. Uncertainty exists over the toxicity caused by adding chemical dispersants to an oil slick and the long-term effects of dispersants application are not well understood. The known harms and potential risks caused by dispersants, in addition to a lack of proven effectiveness and safety, preclude the Council from supporting dispersants.

Oil spill prevention remains the Council’s top priority because once oil is spilled there will always be adverse impacts to human health and the environment. In the event of an oil spill in our region, mechanical recovery and containment of oil spilled at sea should remain the primary response method. The Council also recommends that oil spill response research and development should focus on enhancing and improving mechanical recovery technologies and methods.

The Council’s previous position on dispersant use was adopted in 2006, after years of promoting research and testing to increase knowledge about dispersants and the environmental consequences of their use. In the intervening years, the Council has continued to track developments and analyze peer reviewed scientific literature from around the world regarding the use of dispersants. Discussion and work to develop this update have occurred over the past year, with the final approval taking place at the directors’ meeting in Seward, Alaska, on September 23, 2022.

Details

Further materials on the evidence and rationale supporting the position update are currently being finalized by the Council for publication in early 2023.
