These CFRs seem to be "catch all" language prohibiting litter of every type imaginable on all forest property. "Waste water" could be interpreted to mean you can't even pee on the ground, so its a broad brush regulation. This is not the same as a Forest Order requiring a hiker to pack out poop in a specific area. A Forest Order requires compliance with NEPA, and we know they did not complete the environmental review process.
I've always packed my TP until the first good chance to burn it. If I don't get a chance to burn it, I pack it out, no big deal to me. I've seen a lot of it buried with good intentions, but dug up by animals.
