Memorandum To: Dave Novak, EPA From: Mike Baker, COPA Date: January 30, 1995 Re: Comments on the ABB Expedited Remediation Proposal We are in favor of an expedited remediation of ABB. Transportation by rail to USPCI is, in general, an acceptable remedy for the PCB-bearing soil. However, there are a number of other remedies commercially available and demonstrated at full scale that result in permanent reduction in volume, mobility and/or toxicity. We are not in favor of switching from Superfund to TSCA until, and unless, the proposed TSCA revisions are in effect. The reason that the Superfund process has performed rather poorly at the other seven Bloomington sites is not due to the procedures and safeguards of Superfund, but due to the Consent Decree. If an expedited remediation of ABB is desired, it is not necessary to abandon Superfund and allow private remediation under TSCA to do so. An EE/CA could be prepared for the ISF at ABB within two months, and several more months would be required for public comment and administrative tasks on the part of EPA. If EPA abandons the EE/CA-public comment process now in favor of private cleanup by Westinghouse under the current TSCA regulations, the message sent to the community will be very damaging. If the ISF at ABB can be disassociated from the other Bloomington PCB waste for purposes of implementing an expedited remedy under TSCA, then the ISF at ABB can be similarly disassociated from the other sites when performing an EE/CA under Superfund. It is essential not to shortcut the regulatory procedures that currently apply (EE/CA) given the level of public involvement and general dissatisfaction. It is likely that an EE/CA will conclude that transport by rail to USPCI is an appropriate and cost effective remedy, but the EE/CA will also document, for the benefit of all parties and the public, the advantages and disadvantages of alternatives. The volume of soil stockpiled at the ISF is sufficient for several promising alternative technologies to be cost competitive with landfilling, and they offer the advantage of reduction of waste volume, mobility or toxicity. Table 1 lists several technologies which have been demonstrated at full-scale for PCB treatment. Cost data is detailed in Table 2. The features of the three regulatory environments that concern remediation of the ISF at ABB are summarized in Table 3.
