If there's a spill, the first key is first response. Get there and get it contained to limit your liability. Then working with local authorities, devise a plan to remediate the area very quickly. Fortunately, we've been successful in doing that, and we've have had very few issues. We've had no issues of any great magnitude. Based on the regulations today, we see the liability as being well contained.
Obviously we carry appropriate insurance policies to be able to deal with anything that may happen.
