Scattering of Ashes

Recently a client told me that a funeral director (in Wisconsin) told her that scattering ashes was punishable by fine. Odd, I had not heard of this fine before. And during the time when my father died, the cremation facilitator told me there was no fine because the material was inert, there would be no organic material remaining. I suspect the funeral director in my client's situation was interpreting common law or statues in a way that favors funerals. I'll have to check the statutes and see what I can determine on this question.

Has anyone else out there had experience with scattering ashes and fines?
