No, not really.
Oh Tom, Tom, Tom theories like these are where the rumors/inaccuracies/problems start surrounding the death process. Let's just get to the facts:
Persons can stipulate, in -their -will, that their ashes be scattered at "such and such location". Eg.: the Ocean. Or a certain beach or scenic overlook. Or certain favorite lake they'd known, etc....
You can stipulate anything you want, but it's legally complicated. Federal, State, County and/or locals laws apply. Cremains are human remains in an emotional sense, but legally, not so much. You see, they are inert… in a chemical sense that is not really a human being in that urn… no DNA, diseases, etc.
That brings us to permissions. We know how you love permissions. Just doing your own thing is just ethically wrong. The fact is you are dumping something, somewhere. If someone decided YOUR flowerbed is where they want their loved one to be for eternity, then,
without your permission… and dumps away under the cover of darkness, I'll go out on a limb here, but guess you'd be upset your private property had been violated. So, just dumping cremains out in the public space is NOT OK! The, daily "don't ask for permission" rant DOES NOT apply here, IMO.
So, Federal law generally allows you to dispose of cremains at sea: BUT, you need to be more than three miles from land and the water is over 600 feet deep. There are other rules: in a nut shell don’t toss ANYTHING non-biodegradable overboard, including the urn itself. This defines "the sea", NOT the beach. The beach could be private, city property, part of a state or national park. You need to contact the authority that oversees the beach in question.
If you think MD'ers get a bad rap, think about people dumping cremains just any place. Ya know why people do that? A) they're too lazy to do the leg work B) CHEAP, cuz doing it respectfully and legally is expensive. Let's continue...National Forrest - no, don't do it. State and local parks: better find out and get the proper permits. Most national parks, yes, but not all of them. Parks that do allow scattering require a special use permit.
In most states, you can scatter ashes on private property, as long as you have the permission of the land’s owner. You cannot scatter cremains into inland waters.
the little box containing the ashes (which amount to no more than a cup-or two,
No, hard no. Roughly 6-9 pounds of cremains.
Hence gold teeth, toe-tags like yours, etc... can be included.
As in my post #2: "Some minor processing occurs for removal of foreign objects, like pace maker leads, dental appliances, etc." They may miss things, but in general the only thing in the bag is the cremains and the ID tag.
