I understand what the exceptions are. I'm just asking why you are not also applying those to non-federal lands.
You're essentially saying that an authority can't carry out the project if they've given money or will partly authorize the project. Why do you not also have a provision related to a project on non-federal lands? It seems logical. You're completely missing that third category of where projects can occur: federal lands, non-federal lands, and foreign lands, but you don't have the non-federal lands.
