The 26 Anniversary of the Exxon Valdez Oil Spill in Alaska

Posted On March 24, 2015 by

Today marks the 26 anniversary of the Exxon Valdez oil spill in Alaska where nearly 11 million gallons of oil spewed into the ocean over the course of three days. Exxon failed to carry out its pre-approved oil spill response plan because their response barge was “out of service and unavailable for use.” Even if the barge were operational, it lacked enough skimmers and booms to handle the spill. Government officials and local volunteers quickly began spearheading the cleanup. Despite their best efforts to make up for Exxon’s systematic failure, only 14 percent of the spill was removed. This massive spill caused then Governor of Alaska, Steve Cowper, to declare a state of emergency. Oil from the spill can still be found today and some places may be as toxic as they were 26 years ago.

Now, more than two decades after the Exxon Valdez oil spill, the Arctic Ocean is still threatened by risky oil drilling. The Bureau of Ocean Energy Management (BOEM) released an analysis that showed a 75 percent chance of at least one major spill if companies were allowed to develop oil in the Chukchi Sea off Alaska’s northwest coast. Rapidly forming sea ice, fog, high winds, extreme cold and lack of infrastructure make it nearly impossible to clean up an oil spill in Arctic waters. Even in the Gulf of Mexico, only 19 percent of the oil from the Deepwater Horizon oil disaster was removed or dispersed.

Tell the Department of Interior to Protect Walruses

Posted On October 10, 2014 by

When I first saw the photo above, I couldn’t believe it was real.

Those are 35,000 walruses – packed together onshore in Alaska.

If you’re saying to yourself “that doesn’t look normal,” you’re right. Packs like this were unheard of before 2007.

The sea ice walruses usually rest on is disappearing, forcing them to come all the way to shore between feedings. These changes to sea ice are putting walruses at great risk.

Now, Shell has proposed a plan to drill for oil in the waters where walruses live, feed, and raise their young. Risky Arctic drilling will cause even more stress for the walruses that are already struggling to cope with the loss of sea ice. We need to stop Shell’s plan.

You Won’t Believe What Shell’s Doing Now

Breaking news: Shell has announced 2015 plans that could bring not one, but two drilling rigs to the Chukchi Sea. That spells double trouble for the Arctic—say NO to Shell’s plan.

Shell’s already tried and failed. When Shell tried to drill in the Chukchi Sea two years ago, it had to stop after just one day because a huge ice floe drifted into the area. A couple months later, the company’s drillship caught fire. Their proposed oil spill containment system? It was “crushed like a beer can” during testing.

By the end of the season, Shell’s drillship was hobbled by mechanical difficulties and had to be towed to Asia.

Help Us Say No to Risky Arctic Drilling

Breaking: The U.S. government is beginning to make plans for future offshore oil and gas operations—and those plans could open Arctic waters to risky drilling.

This follows Shell Oil’s decision to abandon Arctic drilling this summer, after an accident-plagued 2012.

If a disaster like BP Deepwater Horizon happened in the Arctic, spill response would be even more challenging. The Arctic’s sea ice, freezing temperatures, gale force winds, and lack of visibility could make cleanup next to impossible.

When It Comes to Arctic Drilling, Cumulative Effects Add Up

Posted On November 22, 2013 by

Workers in the ArcticPicture five oil rigs in your nearby ocean. These oil rigs are different sizes and operate in different locations and at different times. Each of these rigs has an impact on marine life and water quality, but each to a different degree.

When the individual impacts of each of these rigs accumulate over time and space, it is known as “cumulative effects.” Think of this like a snowball fight. It’s easy to dodge snowballs when you’re up against one other person.  But when five people are throwing snowballs at you, it’s much harder to avoid getting hit. And the more hits you take, the more bruises you’re bound to get.

Cumulative effects recognizes that the impact of an individual action may be relatively minor on its own, but could be much more significant when considered in combination with the effects of other past, present and future actions. Effective assessment of cumulative effects is one of the most challenging issues in resource management.

Why Now is Not the Time for a New Offshore Lease Sale in the Chukchi Sea

Just before the government shutdown brought federal agencies to a standstill at the beginning of October, the Bureau of Ocean Energy Management (BOEM) issued a “call for information” for a potential new oil and gas lease sale in the Chukchi Sea off the coast of northwest Alaska. A new Chukchi Sea lease sale would allow oil and gas companies to buy additional oil leases in one of the most remote and challenging environments on the planet. The response to the call for information is easy: now is not the time to sell new oil and gas lease sales in the Chukchi Sea.

The last oil and gas lease sale in the Chukchi Sea was in 2008. Since that time, the Deepwater Horizon oil disaster in the Gulf of Mexico reminded the world that when things go wrong, offshore drilling can have catastrophic consequences for fish and wildlife, marine and coastal environments, and residents of affected coastal communities. The Deepwater Horizon disaster also triggered new safety and environmental protection requirements for oil and gas companies that wish to drill in Arctic waters.

Two years after the Deepwater Horizon disaster, Royal Dutch Shell tried its hand at drilling in the Arctic and experienced a whole series of disasters. Among other things, a massive ice floe blocked access to one drilling site for about two weeks, the company’s drilling vessels violated their air emission permits, the drillship Discoverer suffered propulsion problems and had to be towed to port, and the drilling unit Kulluk ran aground off Kodiak Island and had to be salvaged by outside consultants. For all that, Shell failed to complete a single Arctic well.

Reprieve from Arctic Drilling Creates an Opportunity for Progress

What a difference a year makes. Last year at this time, Shell Oil had a fleet of vessels in the Arctic Ocean in an attempt to drill for oil off the north and northwest coasts of Alaska. But Shell’s 2012 season was plagued by mishaps and mistakes, from the near-grounding of the drillship Noble Discoverer last July to the all-too-real grounding of the drilling unit Kulluk on New Year’s Day this year.

In the end, Shell failed to complete a single Arctic well, and both the Noble Discoverer and Kulluk were so badly damaged that they were towed to Asia for repair earlier this year. In fact, the EPA just fined Shell $1.1 million for unauthorized levels of air pollution from the two vessels — yet another reminder that Shell was not prepared for its Arctic operations.
