A coalition of environmental groups filed a lawsuit against the federal government Tuesday morning over Shell's Arctic oil spill response plan. The lawsuit is not intended to stop Shell from drilling in the Arctic this year, but it is supposed to change the way the Bureau of Safety and Environmental Enforcement deals with future permitting. That office approved Shell's response plan in case of a spill in the Beaufort and Chukchi seas.

The environmental groups say that plan is inherently flawed, and could set the stage for a disaster if Shell experiences a blowout or spill.
