I support the addition of the ten proposed sites to the General Superfund Section of the National Priorities List. My reason in commenting on this proposed rulemaking is in support of the decision of EPA to withdraw the Arnold Engineering Development Center from the proposal to be added to the NPL. While I recognize the importance of listing sites under NPL where necessary, I think it was appropriate for EPA to entirely remove AEDC from proposal to the NPL. The data used to calculate the site score was taken from data in the 1980’s. New data shows that even the most contaminated area, the Retention Reservoir, had levels of PCB that were below 5 ppm where EPA’s current levels of PCB for clean up are 10 ppm for residential areas and 25 ppm for instustrial areas. Moreover, this area is being actively addressed under RCRA. I imagine there are numerous other sites that are more polluted, contaminated, and in dire need of listing under the NPL than the AEDC. I hope EPA shifts its focus towards those sites and removes AEDC from the NPL proposal list.
