The state and regional clean air agencies said they’ve been waiting for more guidance from the U.S. Environmental Protection Agency (EPA), but U.S. District Court Judge Marsha Pechman said the agencies have a responsibility to enforce the state clean air plan that’s already in place, ruling in favor of the plaintiffs. One issue raised in court is that Washington’s State Implementation Plan for regulating air pollution is tougher in some ways than federal greenhouse gas standards, and the agencies weren’t sure they could enforce it. However, the judge pointed out that the EPA has “repeatedly approved” the state plan. Brimmer says now, it just needs to be put into practice. “The reality is that, despite a lot of good policy statements about greenhouse gases and climate change in Washington, we really have not regulated greenhouse gas pollution very much, particularly from existing sources like these big refineries.” The plaintiffs have called the decision a win for the economy as well as the environment. Together, the five oil refineries in question are responsible for an estimated 6 to 8 percent of the climate-change pollution in the state. They are located in Anacortes, Blaine, Ferndale and Tacoma. They were represented by the Western States Petroleum Association. More information about the case has been posted on the Washington Environmental Council website, www.wecprotects.org.
