Land Disposal Restrictions: Site-Specific Treatment Standard Variance for Selenium Waste for Chemical Waste Management, Chemical Services, LLC

The Environmental Protection Agency (EPA or Agency) is today granting a site-specific treatment standard variance from the Land Disposal Restrictions (LDR) treatment standards for a selenium-bearing hazardous waste generated by the glass manufacturing industry. EPA is granting this variance because the chemical properties of the waste differ significantly from those of the waste used to establish the current LDR treatment standard for selenium (5.7 mg/L, as measured by the Toxicity Characteristic Leaching Procedure (TCLP)), and the petition has adequately demonstrated that the waste cannot be treated to meet this treatment standard. EPA is granting this variance to CWM Chemical Services LLC (CWM (Model City, NY)) to stabilize a selenium-bearing hazardous waste generated by Guardian Industries Corp. (Guardian) at their RCRA permitted facility in Model City, New York. With promulgation of this final rule, CWM may treat the Guardian waste to an alternate treatment standard of 28 mg/L, as measured by the TCLP. CWM (Model City, NY) may dispose of the treated waste in a RCRA Subtitle C landfill, provided they meet the applicable LDR treatment standard for any other hazardous constituents
