If this is considered "related to bicycling", pretty much any ecological policy would be as we do ride our bikes in the environment.
If it actually poses a health hazard to crews working with it, I'd certainly prefer not to ride or walk on the surface. I'd want to know a good deal more and have input from a variety of sources before discounting any potential for danger. I don't actually know enough about it to have an opinion one way or the other, but the State assuring me it was safe wouldn't actually provide that much assurance.
