Rowdie nailed it. And yes, you are allowed to remove it yourself on a private dwelling.
Come to think of it, the floor tiles weren't even the problem at UND. It was the adhesive that contained asbestos (at least, in our building).
I remember chuckling about it being damn near impossible to get an airborne fiber of asbestos from the adhesive and yet they had to go full on OSHA/EPA abatement because it's a public building.
At the same time, if 20% of the insulators got lung cancer, I'd think that was a little high and indicative of this stuff is for real when it comes to lung damage. We are endlessly inundated with those Sokolove commercials for a reason.

Note: I believe OSHA's lifetime exposure limit is 1 fiber for a reason. Anyone that's stood for anytime at a busy intersection has most likely already exceeded that limit. Or, done a brake job on vehicles back in the 80s.
Note 2: If I remember correctly, the real problem with asbestos isn't its chemical composition as it's very inert. It's a mineral and its crystal structure is that of a barbed arrowhead (laymen's terms). If inhaled it gets stuck in the lung, just like a barbed arrowhead or hook, and slowly moves through the lungs causing scarring that is the real problem.
