Funny thing about asbestos, it is a mineral mined out of naturally occurring rock... I bet there are places where it outcrops and you can just bend down and break a piece off of the rock face. Does that make that property a Superfund site?
In 2006, 2.3 million tonnes of asbestos were mined worldwide, in 11 or 12 countries. Russia was the largest producer with about 40.2% world share followed by China (19.9%), Kazakhstan (13.0%), Canada (10.3%), and Brazil (9.9%)
None in USA...........
