Amendment to industry’s plan for preventing and responding to oil spills approved

Council concerned that hard-fought protections would be delayed

In October, the Alaska Department of Environmental Conservation, or ADEC, approved an amendment to Alyeska’s contingency plan for oil spills from the Valdez Marine Terminal.

New oil skimming systems

One of the major changes incorporates new oleophilic oil skimmers, which will also be on the soon-to-arrive Edison Chouest barges, into the plan. These skimmers, along with the Current Buster booming system, make up a more advanced oil recovery system. The new system allows responders to operate and collect oil for longer periods, as less water is collected requiring less storage.

Oil spill contingency plans for Prince William Sound under review

Many changes stemming from transition of marine services contractor to Edison Chouest

Prince William Sound Tanker Oil Spill Contingency Plan

By Linda Swiss
Council Project Manager

Updates to two oil spill prevention and response contingency plans are currently underway. The Alaska Department of Environmental Conservation, or ADEC, solicited public comments regarding the changes to the spill prevention and response plans this past summer.

The plans are prepared by the operators of Alyeska’s marine terminal and oil tankers and are subject to state approval. These plans specify what operators will do to prevent and clean up oil spills. There are separate plans for spills from the Valdez Marine Terminal and from the tankers that carry oil. Both plans undergo an approval process approximately every five years. With the marine services transition in Prince William Sound, Edison Chouest Offshore’s new equipment means the details in the plans will change, triggering a public review.

In 43 pages of formal comments submitted to ADEC in August and September, the Council made a number of recommendations to either maintain the same level of preparedness or improve the proposed plans.

By July of 2018, Edison Chouest Offshore, or ECO, of Louisiana will be the marine services contractor for oil tankers and the terminal in Prince William Sound. Until then, Alyeska and ECO will be working with Crowley Maritime, the contractor who currently provides those services, on a smooth transition between the two contractors. These services include escort tugs, general purpose tugs, oil recovery storage barges and associated personnel, all of which are key oil spill prevention and response assets for Prince William Sound. For instance, two state-of-the-art escort tugs accompany every laden tanker that leaves Port Valdez. One tug is tethered through the confined waterway called the Valdez Narrows, and one tug stands by at Hinchinbrook Entrance until the tanker is 17 miles into the Gulf of Alaska. The primary responsibility of these escort tugs is to rescue or “save” a tanker that may experience problems and prevent oil from spilling, and initiate response efforts should these prevention measures fail.

Council applauds decision to keep public engagement tool for spill response in Alaska

Recent council concerns about a proposed change to Alaska’s spill response plan have been alleviated for now. However, the council is following a new proposal that also has the potential to affect stakeholder input.

In a letter to the council on September 1, the Alaska Department of Environmental Conservation, or ADEC, announced that its proposal to change the Regional Stakeholder Committee had been withdrawn. The Regional Stakeholder Committee is a vital tool for public involvement during oil spills, and has been effective for communication during spill drills and exercises in Prince William Sound for over a decade.

Early in 2016, the Alaska Regional Response Team, or ARRT, a group made up of 15 different federal and state agencies that share responsibilities for managing oil and chemical spill responses in Alaska, proposed changes that could have reduced the council’s, and the public’s, access to important information about a spill. The change would also have reduced citizens’ input to spill response leaders.

Involving citizens was recognized by Congress and Alaskans as an important aspect in oil-spill laws and regulations that were overhauled after the Exxon spill.

During the public comment period that followed, the council and several local communities and organizations supported keeping the committee as it was, rather than splitting stakeholders into two groups. One of the new groups, which would have included the council, would have received far less information and access to decision-makers than the other.

ADEC stated that the workgroup that put the proposal forward met on August 31, at which time a determination was made to withdraw the proposal.
