Why, all of a sudden, is EPA calling this a Superfund site?

The Henry's Knob former mine site is not a Superfund site. It is a Superfund alternative site. The difference is a Superfund site is listed on the National Priorities List where a Superfund alternative site is not. However, a Superfund alternative site is subject to the same laws and regulations of a Superfund site, but the remediation of the site will not funded by the U.S. government. ABB, as a potentially responsible party, is paying for the investigation that is underway and for any future activity required by the EPA.

This Superfund classification needs to be corrected by the EPA to a Superfund alternative site.
