A Contra Costa County judge has thrown out the environmental impact report for the massive Chevron Richmond oil refinery expansion, according to the Chron. Contra Costa County Superior Court Judge Barbara Zuniga sided with activists and environmentalists who sued to stop the controversial project, ruling that the EIR was too vague on whether Chevron would be allowed to start refining dirty crude oil. Such refining could cause significant environmental problems. The judge's decision puts the future of the project in doubt, because it may force the city to redo parts of the EIR and re-approve it. But that could be a big problem for Chevron, because it no longer controls a majority of the Richmond City Council. After last November's election, progressives now have a 4-3 majority on the council with the addition of Jeff Ritterman, a physician who ran specifically against the Chevron refinery expansion plan.
