The Clean Water Act trial is only one component of the fallout from the 2010 spill. BP has already spent more than $28 billion to pay for cleanup and claims. It has taken a $43 billion charge to cover all of its costs, including under the Clean Water Act. And in a separate part of the multifaceted proceedings in New Orleans, the company is still fighting with plaintiffs' lawyers over private business and economic claims that were once estimated to total less than $8 billion but are now headed toward $10 billion or possibly much more.
