Download or read book Final Disposal Options for Mercury written by and published by . This book was released on 1994 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laboratory testing was completed on chemical stabilization and physical encapsulation methods that are applicable (to comply with federal and state regulations) to the final disposal of both hazardous and mixed hazardous elemental mercury waste that is in either of the following categories: (1) waste generated during decontamination and decommissioning (D and D) activities on mercury-contaminated buildings, such as Building 9201-4 at the Oak Ridge Y-12 Plant, or (2) waste stored and regulated under either the Federal Facilities Compliance Agreement or the Federal Facilities Compliance Act. Methods were used that produced copper-mercury, zinc-mercury, and sulfur-mercury materials at room temperature by dry mixing techniques. Toxicity Characteristic Leaching Procedure (TCLP) results for mercury on batches of both the copper-mercury and the sulfur-mercury amalgams consistently produced leachates with less than the 0.2-mg/L Resource Conservation and Recovery Act (RCRA) regulatory limit for mercury. The results clearly showed that the reaction of mercury with sulfur at room temperature produces black mercuric sulfide, a material that is well suited for land disposal. The results also showed that the copper-mercury and zinc-mercury amalgams had major adverse properties that make them undesirable for land disposal. In particular, they reacted readily in air to form oxides and liberate elemental mercury. Another major finding of this study is that sulfur polymer cement is potentially useful as a physical encapsulating agent for mercuric sulfide. This material provides a barrier in addition to the chemical stabilization that further prevents mercury, in the form of mercuric sulfide, from migrating into the environment.

Available in PDF, EPUB and Kindle. Book excerpt: The EPA regulates haz. wastes (such as mercury) under the Resource Conservation & Recovery Act (RCRA). Under RCRA, mercury-containing haz. waste must meet specific treatment standards before land disposal. But, certain difficult to manage waste due, in part, to its large particle size, can follow alternate debrisÓ standards that provide diverse treatment options. This report examines: the mechanisms that EPA uses to track the treatment & disposal of debrisÓ & the quantity of this waste: the extent to which EPA, states, & ind. share a common understand. of the types of debrisÓ that can be treated & disposed of as debris: & EPA & state controls that are in place to monitor compliance with EPA's treat. & disposal require. for debrisÓ.

Download or read book Disposal of Activated Carbon from Chemical Agent Disposal Facilities written by National Research Council and published by National Academies Press. This book was released on 2009-09-08 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the last two decades, the United States has been destroying its entire stockpile of chemical agents. At the facilities where these agents are being destroyed, effluent gas streams pass through large activated carbon filters before venting to ensure that any residual trace vapors of chemical agents and other pollutants do not escape into the atmosphere in exceedance of regulatory limits. All the carbon will have to be disposed of for final closure of these facilities to take place. In March 2008, the Chemical Materials Agency asked the National Research Council to study, evaluate, and recommend the best methods for proper and safe disposal of the used carbon from the operational disposal facilities. This volume examines various approaches to handling carbon waste streams from the four operating chemical agent disposal facilities. The approaches that will be used at each facility will ultimately be chosen bearing in mind local regulatory practices, facility design and operations, and the characteristics of agent inventories, along with other factors such as public involvement regarding facility operations.

Download or read book Mercury and Arsenic Wastes written by United States. Environmental Protection Agency and published by William Andrew. This book was released on 1993-12-31 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides state-of-the-art information on removal, recovery, treatment, and disposal of mercury and arsenic wastes, based on a workshop held in Alexandria, Virginia in August 1992. The goals of the workshop were: 1) to examine the fundamentals and analytical issues related to mercury and arsenic compounds; 2) to disseminate information on the state of practice of source reductiontechnologies that recover or remove mercury and arsenic from industrial wastes'and recycling or reuse processes; and 3) to discuss existing and emerging technologies that treat industrial wastes or contaminated soil and water, and the storage and disposal of treated wastes. The book is presented in two parts Mercury and Arsenic and contains extended summaries of papers presented at the workshop. The areas covered are fundamentals, analytical techniques/characterization; removal, recovery, and reuse; and treatment, storage, and disposal.

This book was released on 2005 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is the outcome of a workshop arranged to support the development of the EU strategy on mercury (based on the Council decision in December 2002), and to support international conventions aimed at reducing emissions, environmental contamination and human exposure to mercury. Specific objectives of the workshop were, a) To summarise the state-of-the-art on sources, emissions-distribution-deposition-exposure, options and technologies to reduce uses and releases, the waste problem and waste management options, and health/environmental impacts of mercury. b) To identify and discuss priority problem areas. c) To derive recommendations for an effective European mercury abatement strategy especially: - How to deal with the surplus mercury from the chloralkali industry? - How to deal with mercury in products and waste? - How to deal with mercury from coal-fired power plants and other atmospheric point sources? d) To review national, regional and international programs e.g. the UNEP mercury programme and the revision of the CLRTAP Protocol on Heavy Metals. The report consists of an executive summary, reports from group discussions and background papers prepared by participants. About 100 participants representing research, policy, industry and NGOs were present at the workshop.
