Restoration along Oregon’s Willamette River Opens up New Opportunities for Business and Wildlife

This is a post by the NOAA Restoration Center’s Lauren Senkyr.

Salmon, mink, bald eagles, and other wildlife should be lining up to claim a spot among the lush new habitat freshly built along Oregon’s Willamette River. There, a few miles downstream from the heart of Portland, construction at the Alder Creek Restoration Project is coming to a close. Which means the reshaped riverbanks and restored wetlands are open for their new inhabitants to move in.

This 52 acre project is the first habitat restoration effort for the Portland Harbor Superfund Site and has been implemented specifically to benefit fish and wildlife affected by years of industrial contamination in the harbor.

Salmon, lamprey, osprey, bald eagle, mink, and others will now enjoy sandy beaches, native vegetation, and large pieces of wood to perch on or hide underneath. These features replace the saw mill, parking lots, and other structures present on the property before it was purchased by Wildlands, Inc. Chinook salmon and osprey have already been seen seeking refuge and searching for food in the newly constructed habitat.

Wildlands is a business that intends to sell ecological “credits” from this restoration project. The credits that the Alder Creek project generates are available for purchase to resolve the liability of those who discharged oil or hazardous substances into Portland Harbor.

Construction on the restoration site began in the summer of 2014. First, hundreds of thousands of yards of wood chips were removed from the site of a former saw mill and several buildings were demolished. A channel was excavated on the western portion of the site, which was continued through the eastern half of the site when construction resumed in 2015.

Also this year, efforts involved removing invasive vegetation, planting native vegetation, and installing large wood structures along the channel to create ideal places for young fish to rest, feed, and hide from predators.

After a final breach of the earthen dam dividing the restoration site this September, water now flows across the newly restored area. Once additional planting is completed this winter, the project will officially be “open for business,” although some entrepreneurial wildlife are already getting a head start.

Who Pays for Oil Spills?

This is a post by Kate Clark, Acting Chief of Staff with NOAA’s Office of Response and Restoration.

Oiled boom and marsh in Louisiana.

The Oil Pollution Act of 1990 states that those responsible for releasing oil and other hazardous materials pay for all costs associated with the cleanup operations, as well as the assessment of environmental impacts and necessary restoration. (U.S. Coast Guard)

After every major oil spill, one question comes up again and again: Who is going to pay for this mess?

While the American public and the environment pay the ultimate price (metaphorically speaking), the polluter most often foots the bill for cleanup, response, and restoration after oil spills.

In sum: You break it, you buy it. But our unspoiled coasts are priceless, and we would rather protect—or at least minimize impacts to—them as much as possible. Which means federal dollars are invested in ensuring top-notch experts are ready to act when oil spills do strike. (Stay tuned for more on that.)

So, Who Pays to Clean up an Oil Spill?

When an oil spill occurs, there are very clear rules about who pays for the direct response activities, the cost of assessing environmental damages, and implementing the necessary restoration.

The Oil Pollution Act of 1990, one legacy of the 1989 Exxon Valdez spill, spells out that those responsible for the pollution pay for all costs associated with the cleanup operations. However, similar to a car accident, insurance companies aren’t going to start writing checks without first looking at the circumstances.

But time is of the essence when oil hits the water, so oil companies and transporting vessels are required to have plans in place to respond immediately. In the rare instances when insurance companies investigate the details of legal (and hence, monetary) responsibility and hesitate to pay additional costs, the U.S. Coast Guard is able to set up an immediate source of funding for federal and state agencies and tribes who support the oil spill cleanup, which pays for their contributions to the response.

If the polluter is ultimately deemed liable for the spill, then they reimburse all expenses to the U.S. Coast Guard. Meaning the polluter pays for the cost of the oil spilled.

What About Restoration After Oil Spills?

Well, what about the environmental impacts left behind after the cleanup ends and everyone goes home? Does the American public pay to restore the animals and plants harmed by the spill?

Scientist leans over a boat to retrieve a dead Kemp's ridley sea turtle from the water.

It takes an average of four years to reach a settlement for environmental damages and then begin restoration after an oil spill. As a result, our job is not only to enforce pollution regulations but to ensure the right type and amount of restoration is achieved. (NOAA)

Nope. Again, the Oil Pollution Act states that parties that release hazardous materials and oil into the environment are responsible not only for the cost of cleaning up the release, but also for restoring any “injuries” (harm) to natural resources that result.

As the primary federal steward (“trustee”) for coastal animals and habitat, NOAA is responsible for ensuring the restoration of coastal resources in at least two specific cases.

First, for coastal resources harmed by releases of hazardous materials (e.g., oil and chemicals) and second, for national marine sanctuary resources harmed by physical impacts (e.g., when a ship grounds on coral reefs in a marine sanctuary).

But What if Polluters Don’t Have to Pay for Everything?

It is possible, though extremely rare, that a polluter can be found not to be liable (e.g., the pollution was caused by an act of war) or the polluter can reach its limit of liability under the law.

So, does the money for cleanup and restoration then come from American taxpayers?

Nope. In these cases, the costs are then covered by the Oil Spill Liability Trust Fund. This fund accrues from taxes on most domestically produced and imported oil. The oil companies, often those responsible for spills, are paying into this fund.

When a spill occurs, those involved in the response, cleanup, and damage assessment can access these funds if the polluter is unknown, unwilling, unable, or not liable for paying the spill’s full costs. For response activities, the fund will cover costs associated with preventing (in the case of a grounded ship that hasn’t released oil yet), minimizing, mitigating, or cleaning up an oil spill.

For natural resource damage assessment, the fund will cover costs associated with assessing an area’s natural resource damages, restoring the natural resources, and compensating the public for the lost use of the affected resources.

Of course, polluters aren’t always eager to accept liability, and accurately assessing environmental damages can take time. In fact, it takes an average of four years to reach a settlement for these damages and then begin restoration after an oil spill. As a result, our job is not only to enforce pollution regulations but to ensure the right type and amount of restoration is achieved.

That means, once again, dollars from polluters are essentially paying for oil spills.

So, the Public Doesn’t Pay for Anything?

Well, okay. The same as with your local fire department, public tax dollars are spent developing a highly trained group of professional emergency response and restoration experts. The more prepared we are to respond when an oil spill happens, the sooner a community can recover, environmentally and economically, from these unfortunate events.

When we aren’t providing direct support to an oil spill (or other marine pollution event), NOAA’s Office of Response and Restoration is hard at work training ourselves (and others) and developing tools and best practices for emergency response and assessment of impacts to natural resources.

Better Safe (and Prepared) Than Sorry

Oil spills can happen at any time of day and any time of year (including holidays). We have to be ready at any time to bring our scientific understanding of how oil behaves in the environment, where it might go, what it might impact, what can be done to address it, and what restoration may be needed.

And we think being prepared before a spill happens is a worthy investment.

NOAA Is Supporting Oil Spill Response in Kentucky After Tugs Collide on Mississippi River

On the evening of September 2, 2015, two tug boats collided on the Mississippi River near Columbus, Kentucky, spilling slurry oil into the river.

Early reports, which later may be corrected, indicate an estimated 120,500 gallons of oil were released from a hole in the cargo tank of a barge being towed by the tug Dewey R during the collision. The spill and ensuing response closed the river between mile markers 938 and 922, south of Paducah, Kentucky, but the waterway was reopened to vessel traffic as of September 8.

At the request of the U.S. Coast Guard, NOAA’s Office of Response and Restoration is supporting the response and sending oil spill and data management experts to the scene of the spill. NOAA scientific support coordinators are providing a variety of information for the response, including river flow forecasts, chemistry of the spilled oil, a submerged oil assessment (because this heavier oil may sink), and other information to help determine where the spill will go and what can be done to protect our waterways and keep commerce moving.

The natural resource agencies also are beginning to assess potential impacts to natural resources, a first step to determining whether restoration is needed as a result of the spill.

Updates from NOAA about this oil spill may be available on IncidentNews.

What Is Slurry Oil?

Slurry oil is a residual oil resulting from the refining process and when spilled, most of it will sink or become suspended in the water column. A U.S. Coast Guard overflight the morning of September 3 revealed a floating sheen of oil four to five miles downstream of the discharge, which is not unexpected with this type of heavy oil.

How Is an Oil Spill in a River Different Than One in the Ocean?

From dams and density to muddy waters and vegetation, rivers offer a very different environment than the ocean during an oil spill.
