Thank you very much for that.
I'd like to take you briefly to environmental response questions. They were raised by my colleague Ms. Blaney. Could you outline for the committee the kinds of scenarios you would face? I'm thinking particularly of the west coast with respect to environmental response. You can just hypothetically think about offshore tankers. There are inshore scenarios. There are pipeline scenarios. What kinds of scenarios do you face? What kinds of response capacity do you have? What kinds of technological advances are in the pipeline? Most important, how do you intersect with private sector response cleanup obligations? What are you in charge of? What are you responsible for? What, for example, is an oil company responsible for?
