Disposal Restrictions: National Treatment Variance To Designate New Treatment
Subcategories for Radioactively Contaminated Cadmium-, Mercury-, and Silver-Containing
Batteries; Direct Final Rule (PDF) (8 pp, 182K About PDF)
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.

Disposal Restrictions: National Treatment Variance To Designate New Treatment
Subcategories for Radioactively Contaminated Cadmium-, Mercury-, and Silver-Containing
Batteries; Proposed Rule (PDF) (1 pg, 146K About PDF)

for these wastes in response to a rulemaking petition from the Department
of Energy. The current treatment standards of thermal recovery for cadmium

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.

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.
