My rather facetious reply does have a root in reality though. ( no offence intended ASM, just that any report on the pollution of the Irish sea or the beaches near the Dounreay facility clearly show that we're not being careful enough....or maybe we weren't careful enough.
Unless the waste is always a current concern then in time someone will decide, "It'll do." will be enough safeguard, especially if it saves money. Can't get a more current concern that underneath folks homes and workplaces.
I like the approach that the more electricity someone uses the higher the tarrif though

What a subtle way to effect a change in behaviour
