LDR Rules and Regulations 2002

Date: October 7, 2002
Citation: 67 FR 62618
Subject: Land Disposal Restrictions: National Treatment Variance To Designate New Treatment Subcategories for Radioactively Contaminated Cadmium-, Mercury-, and Silver-Containing Batteries; Direct Final Rule
Abstract: EPA is taking direct final action to grant a national treatability variance from the Land Disposal Restrictions (LDR) treatment standards for radioactively contaminated cadmium-, mercury-, and silver-containing batteries by designating new treatment subcategories for these wastes in response to a rulemaking petition from the Department of Energy. The current treatment standards of thermal recovery for cadmium batteries and of roasting and retorting for mercury batteries are technically inappropriate, because any recovered metals would likely contain residual radioactive contamination and not be usable. The current numerical treatment standard for silver batteries is also inappropriate because of the potential increase in radiation exposure to workers associated with manually segregating silver-containing batteries for the purpose of treatment. Macroencapsulation in accordance with the provisions for treatment standards for hazardous debris is designated as the required treatment prior to land disposal for the new waste subcategories. This will allow safe disposal of these radioactively contaminated materials.

Subject: Land Disposal Restrictions: National Treatment Variance To Designate New Treatment Subcategories for Radioactively Contaminated Cadmium-, Mercury-, and Silver-Containing Batteries; Proposed Rule
Abstract: EPA is proposing to take direct final action to grant a national treatability variance from the Land Disposal Restrictions (LDR) treatment standards for radioactively contaminated cadmium-, mercury-, and silver-containing batteries by designating new treatment subcategories for these wastes in response to a rulemaking petition from the Department of Energy. The current treatment standards of thermal recovery for cadmium batteries and of roasting and retorting for mercury batteries are technically inappropriate because any recovered metals would likely contain residual radioactive contamination and not be usable. The current numerical treatment standard for silver batteries is also inappropriate because of the potential increase in radiation exposure to workers associated with manually segregating silver-containing batteries for the purpose of treatment. Macroencapsulation in accordance with the provisions for treatment standards for hazardous debris is proposed as the required treatment prior to land disposal.

Subject: Land Disposal Restrictions: Site-Specific Treatment Variance to Chemical Waste Management, Inc.; Direct Final Rule
Abstract: EPA is today taking direct final action by granting a site-specific treatment variance from the Land Disposal Restrictions (LDR) treatment standards for two selenium-bearing hazardous wastes. EPA first granted a variance for these two waste streams three years ago. We are now taking action to extend the variance because: the chemical properties of these two wastes continue to differ significantly from the waste used to establish the current LDR standard for selenium (5.7 mg/L, as measured by the TCLP); and Chemical Waste Management, Inc. (CWM) has adequately demonstrated that the two wastes cannot be treated with current technologies to meet this treatment standard.

Subject: Land Disposal Restrictions: Granting of Two Site-Specific Treatment Variances to U.S. Ecology Idaho, Incorporated in Grandview, Idaho and CWM Chemical Services, LLC in Model City, New York; Final Rule
Abstract: EPA is promulgating two site-specific variances from the LDR standards for wastes generated at U.S. Ecology Idaho, Incorporated (USEII) in Grandview, Idaho, and CWM Chemicial Services, LLC (CWM) in Model City, New York. These waste streams are derived from the treatment of multiple listed and characteristic hazardous wastes, including K088 (spent potliners from primary aluminum reduction) and differ significantly from the waste used to establish the LDR treatment standard for arsenic in K088 non-wastewaters. Accordingly, we are finalizing an alternate treatment standard of 5.0 mg/L Toxicity Characteristic Leaching Procedure (TCLP) for the arsenic in the K088 derived emission control dust from the USEII faacility and for the arsenic in the K088 derived baghouse dust, incinerator ash, and filtercake from the CWM facility.

Abstract: Due to several errors, the table entitled Treatment Standards for Hazardous Wastes that appeared on pages 58298 and 58299 of the November 20, 2001 FR is reprinted in its entirety.
