Research budgets are never sufficient.
Of course, you can never be too informed. It's important to have the right systems in place that allow for all contingencies. As I said at the outset, there are many possible permutations of contaminants, and a wide variety of ecosystems can be exposed to a spill risk. You have to do a lot of studies if you're going to be able to respond effectively.
There was mention earlier of an incident involving two containers in British Columbia. It would have been important to have information about the goods being transported in these containers and to know the potential impact of a spill of these products. All materials can be poisons, and it depends on their concentration, so it's important to be able to model all this information.
