I. Availability of Draft Documents on Internet
Please follow these instructions to access the draft documents from the World Wide Web (WWW): (1) For the draft “Guidance on Demonstrating Compliance With the Land Disposal Restrictions Alternative Soil Treatment Standards,” type http://www.epa.gov/ and (2) For the draft “Interpretative Memorandum on the Stabilization of Organic-Bearing Hazardous Wastes,” type http://www.epa.gov/.
II. Guidance on Demonstrating Compliance With the Land Disposal Restrictions Alternative Soil Treatment Standards
A. What Are the Land Disposal Restrictions (LDR) Alternative Soil Treatment Standards?
The Agency promulgated alternative LDR treatment standards for hazardous soil in the Phase IV rule, published May 26, 1998 (63 FR 28556 and 40 CFR 268.49). The LDR treatment standards apply to soils contaminated with hazardous wastes which are excavated and will be land disposed. Under the LDR regulations, you may elect to meet either the alternative soil treatment standards at 40 CFR 268.49, or the more generic treatment standards at 40 CFR 268.40. The alternative treatment standards require that such hazardous soil be treated to reduce concentrations of hazardous constituents by 90 percent, or to meet the hazardous constituent concentrations that are 10 times the Universal Treatment Standard (UTS) found at 40 CFR 268.48, whichever is greater.
B. What Is Included in the Draft Guidance Document?
The interim guidance discusses the alternative treatment standards and why they were developed. It then presents step-by-step guidance on statistical and non-statistical approaches that can help you measure compliance with the alternative soil treatment standards.
C. Can the Draft Guidance Be Used Now?
We are requesting comment on the guidance before it is finalized. However, since the document provides guidance regarding existing rules, and does not impose any regulatory requirements, it may be referred to for assistance in how to apply those underlying rules.
III. Interpretative Memorandum on the Stabilization of Organic-Bearing Hazardous Wastes
A. What Is the Purpose of This Draft Interpretative Memorandum?
The use of stabilization for organic-bearing hazardous wastes to comply with Land Disposal Restrictions (LDR) has been of interest to the regulated community. This draft interpretative memorandum discusses circumstances where stabilization of hazardous organic constituents may be a permissible form of treatment, where it may be classified as impermissible dilution under the LDR program, and describes factors to consider when making these evaluations.
B. Request for Comment
The Agency is requesting comment on this draft interpretative memorandum prior to being finalized. Specifically, the Agency is seeking comment on the need for this interpretative memorandum, additional situations and factors where stabilization may be inappropriate, as well as appropriate for organic-bearing hazardous wastes, and treatment performance data on cases where stabilization was used to treat organic-bearing hazardous wastes.
The guidance document is not a binding regulation, and any decisions regarding legality of organic stabilization activities must still be Start Printed Page 52920justified on a case-by-case basis, not merely by reference to the guidance document. Within these constraints, persons are free to consult the interpretive memorandum as an aid in addressing issues regarding legality under existing rules of organic stabilization activities.Start Signature
