LDR Rules and Regulations 2011

Date: June 13, 2011
Citation: 76 FR 34147
Subject: Land Disposal Restrictions: Revision of the Treatment Standards for Carbamate Wastes; Direct Final Rule
Abstract: EPA is issuing a Direct Final Rule to revise the Land Disposal Restrictions (LDR) treatment standards for hazardous wastes from the production of carbamates and carbamate commercial chemical products, off- specification or manufacturing chemical intermediates and container residues that become hazardous wastes when they are discarded or intended to be discarded. Currently, under the LDR program, most carbamate wastes must meet numeric concentration limits before they can be land disposed. However, the lack of readily available analytical standards makes it difficult to measure whether the numeric LDR concentration limits have been met. Therefore, we are providing as an alternative standard the use of the best demonstrated available technologies (BDAT) for treating these wastes. In addition, this action removes carbamate Regulated Constituents from the table of Universal Treatment Standards. This Direct Final rule will be effective August 12, 2011 without further notice, unless EPA receives adverse written comment by July 13, 2011. EPA received no adverse comments.

Background information for the above rule is available through Regulations.gov, the government's electronic public docket and comment system. The Docket ID Number is EPA-HQ-RCRA-2008-0332.

Subject: Land Disposal Restrictions: Revision of the Treatment Standards for Carbamate Wastes; Proposed Rule
Abstract: EPA is proposing to revise the Land Disposal Restrictions (LDR) treatment standards for hazardous wastes from the production of carbamates and carbamate commercial chemical products, off-specification or manufacturing chemical intermediates and container residues that become hazardous wastes when they are discarded or intended to be discarded. Currently, under the LDR program, most carbamate wastes must be treated to meet numeric concentration limits before they can be land disposed. However, the lack of readily available analytical standards makes it difficult to measure whether the numeric LDR concentration limits have been met. Therefore, we are proposing as an alternative the use of the best demonstrated available technologies (BDAT) for treating these wastes. In addition, this action proposes to remove the carbamate Regulated Constituents from the table of Universal Treatment Standards.

Citation: 76 FR 18921
Subject: Land Disposal Restrictions: Nevada and California; Site Specific Treatment Variances for Hazardous Selenium Bearing Waste; Direct Final Rule
Abstract: EPA is taking direct final actions to both issue a site- specific treatment variance to U.S. Ecology Nevada (USEN) in Beatty, Nevada and to withdraw an existing site-specific treatment variance issued to Chemical Waste Management, Inc. (CWM) in Kettleman Hills, California. These actions pertain to the treatment of a hazardous waste generated by the Owens-Brockway Glass Container Company in Vernon, California that is unable to meet the concentration-based treatment standard for selenium established under the Land Disposal Restrictions program. The site-specific treatment variance issued to USEN provides an alternative treatment standard of 59 mg/L for selenium as measured by the Toxicity Characteristic Leaching Procedure. EPA has determined that the treatment performed by USEN provides the best demonstrated treatment available for this waste by reducing the potential amount of selenium released to the environment, while minimizing the total volume of hazardous waste land disposed.

Background information for the above proposed rule is available through Regulations.gov, the government's electronic public docket and comment system. The Docket ID Number is EPA-HQ-RCRA-2010-0851.

Subject: Land Disposal Restrictions: Nevada and California; Site Specific Treatment Variances for Hazardous Selenium Bearing Waste; Proposed Rule
Abstract: EPA is proposing to issue both a site-specific treatment variance to U.S. Ecology Nevada (USEN) located in Beatty, Nevada and withdraw an existing site-specific treatment variance issued to Chemical Waste Management, Inc. (CWM) located in Kettleman Hills, California. This proposal pertains to the treatment of a hazardous waste generated by the Owens-Brockway Glass Container Company in Vernon, California that is unable to meet the concentration-based treatment standard for selenium established under the Land Disposal Restrictions program. The site-specific treatment variance proposed to be issued to USEN would provide an alternative treatment standard of 59 mg/L for selenium as measured by the Toxicity Characteristic Leaching Procedure. EPA has determined that the treatment performed by USEN provides the best demonstrated treatment available for this waste by reducing the amount of selenium potentially released to the environment, while minimizing the total volume of hazardous waste land disposed. EPA has also published a direct final rule granting a site- specific treatment variance to USEN, and withdrawing the site-specific treatment variance previously granted to CWM for this same waste without a prior proposed rule. If we receive no adverse comment, we will not take further action on this proposed rule and the direct final rule will become effective as provided in that action.

Background information for the above proposed rule is available through Regulations.gov, the government's electronic public docket and comment system. The Docket ID Number is EPA-HQ-RCRA-2010-0851.
