I’ll be honest, I don’t really see how the Love Canal has much to do with self regulation, as the chemical company involved did go above and beyond the regulations at the time for the containment liner. It only failed when people dug foundations through the middle of it because the local town council forced them to sell the property to the council, and then immediately flagrantly violated the terms of the sale where they agreed to never build on the site by concealing the site’s history and building a school while auctioning off the land to developers for a surrounding neighborhood on the site.
