The United States Environmental Protection Agency (EPA or Agency) is today granting a site-specific treatment variance from the Land Disposal Restrictions (LDR) treatment standards for two selenium- bearing hazardous wastes. EPA is granting this variance because the chemical properties of these two wastes differ significantly from the waste used to establish the current LDR standard for selenium (5.7 mg/L TCLP) and Chemical Waste Management, Inc. (CWM) has adequately demonstrated that the two wastes cannot be treated to meet this treatment standard. CWM intends to stabilize the wastes at their Kettleman City, California facility. Upon promulgation of this final rule, CWM may treat these two specific wastes to alternate treatment standards of 51 mg/L TCLP for the Owens-Brockway waste and 25 mg/L TCLP for the Ball- Foster waste. After treatment to these alternative selenium standards, CWM may dispose of the treated wastes in a RCRA Subtitle C landfill provided they meet the applicable LDR treatment standards for the other hazardous constituents in the wastes. We are granting this variance for three years.
