Land Disposal Restrictions: Site-Specific Treatment Variance for Hazardous Selenium-Bearing Waste Treated by U.S. Ecology Nevada in Beatty, NV

EPA (or the Agency) is granting a site-specific treatment variance, under the Land Disposal Restrictions program, to U.S. Ecology Nevada in Beatty, Nevada for the treatment of a hazardous selenium- bearing waste generated by the Owens-Brockway Glass Container Company in Vernon, California. The Agency has determined that the chemical properties of the waste generated by the Owens-Brockway Glass Container Corporation differ significantly from the waste used in developing the Land Disposal Restrictions treatment standard for selenium-bearing wastes, and as such cannot be treated to the specified treatment level of 5.7 mg/L for selenium, as measured by the Toxicity Characteristic Leaching Procedure (TCLP). The site-specific treatment variance provides an alternative treatment standard of 59 mg/L TCLP for selenium, with the condition that the waste-to-reagent ratio not exceed 1:0.45.
