It's a good question.
First and foremost, on the marine side, the WCMRC reinforcements were a big part of the effort, with more response vessels, more equipment on hand and more personnel to respond to a spill. All of those are critical components.
Let's go back to the pipeline itself and the facilities. We have a very comprehensive leak detection system on the pipeline. One of the neat things we are installing is a high-technology fibre optic cable along virtually the entire pipeline system. Once it's fully operational, that will allow us to hear or sense either activity on the right-of-way or a small leak or some other disruption in the system. One of the great dangers to a pipeline is third party damage. The ability to have a system that senses activity on the right-of-way is an incredible addition to the full suite of leak detection and environmental protection mechanisms on the system.
