If I'm understanding the question correctly, I would say that protecting the public's right to navigation is oftentimes protecting the environment. Oftentimes we see projects.... I'll refer back to the report that we recently released. We saw a very intimate link between protecting water and protecting navigation. I raised the example of the Kalamazoo spill, or even the Husky oil spill, in which people weren't able to navigate the waterways, and there was obviously a link to environmental protection as well.
Currently the act doesn't include any assessment for potential spills, and those can definitely impact waterways. I would ask that a new clause be included in the act, so that when there is an assessment on a project, it looks at what a potential spill could do to navigation and the environment as well.
