What can you tell me about Exxon's spill prevention and response guidelines?

"From what I can tell, Exxon learned a lot through the deeply regrettable and tragic Valdez accident in 1989. From a quick perusal of the Exxon site, it seems that the company has a comprehensive system in place to effectively monitor and prevent spills where at all possible, and to respond quickly and efficiently when spills can't be avoided. Everything from the engagement of an outside party for the best possible well containment technology to providing all field employees with appropriate spill response guidelines shows that the company is thinking through and planning for all worst-case scenarios."
