Update: It’s been announced that a proposed settlement was reached with Seattle to resolve its liability for injured natural resources. Seattle has purchased restoration credits from Bluefield Holdings Inc., a company that develops restoration projects. The city’s credit purchase totals approximately $3.5 million worth of restoration. This is the first natural resource damages settlement to fund restoration through the purchase of credits by a restoration development company.

There is no one-size-fits-all approach to environmental assessments for oil spills or hazardous waste events. We must therefore custom-tailor our technical approach for each pollution incident.
We first determine whether impacts to natural resources have occurred and whether it is appropriate to proceed with a Natural Resource Damage Assessment (NRDA). We collect time-sensitive data, evaluate available research and information about the type of injury, and determine what species and habitats are likely to have been affected. If we determine that habitats, wildlife or human uses have been harmed or could experience significant impacts, we often proceed with a full damage assessment.
Most people don’t want to spill oil onto beaches. But after the disastrous 1989 Exxon Valdez spill covered the remote, rocky beaches of Alaska’s Prince William Sound with crude oil, Al Venosa was itching to do exactly that.
As an environmental scientist with the U.S. Environmental Protection Agency (EPA), Venosa had been called up to Alaska to help study the Exxon Valdez oil spill and its cleanup. In particular, he was interested in an oil spill cleanup technique that was getting a lot of attention at the time—an approach known as “bioremediation.” It involved adding oil-eating microbes and extra nutrients to an oiled beach to accelerate the natural background process of microbes breaking down, or biodegrading, oil.
Bay Long Oil Spill in Louisianaalyssa.grayTue, 09/13/2016 - 17:12
On Sept. 5, 2016, a marsh excavator operated by Great Lakes Dredge and Dock Company tracked over pipeline while performing restoration activities in Bay Long, a sub-estuary of Barataria Bay, discharging approximately 5,300 gallons of crude oil into the Gulf of Mexico. The pipeline was shut in and is no longer leaking. The incident occurred at an active restoration site for the Deepwater Horizon oil spill. The cause of the incident is still under investigation.
