Biomedical waste disposal--Nuclear Regulatory Commission. Final rule

The NRC is amending its regulations to permit licensees greater leeway in disposing of liquid scintillation media and animal carcasses containing tracer levels of hydrogen-3 (tritium) or carbon-14. These rule changes will primarily affect NRC licensed hospitals and medical research institutions. Most licensees presently dispose of these items by sending them to a radioactive waste burial ground or by obtaining special authorization from NRC for incineration or onsite burial. Under the new regulations, the licensee may dispose of specified concentrations of these materials without regard to their radioactivity. The NRC is also amending its regulations to raise the annual limits for disposal of hydrogen-3 and carbon-14 by release to the sanitary sewerage systems. The rule changes will conserve waste burial capacity that is already in short supply.     

Hazardous waste management system: standards applicable to generators of hazardous waste and standards applicable to owners and operators of hazardous waste treatment, storage, and disposal facilities--Environmental Protection Agency. Proposed rule

The Environmental Protection Agency (EPA) is today proposing amendments to its hazardous waste regulations under Subtitle C of the Resource Conservation and Recovery Act (RCRA). These amendments would replace the annual reporting requirements for hazardous waste generators and owners and operators of hazardous waste treatment, storage, ad disposal (TSD) facilities with a biennial survey of representative samples of those populations. This approach will provide verifiable data on a wider range of topics, better serve EPA's long term regulatory needs under RCRA, and reduce significantly the information burden on the regulated community.     

Shipping hazardous waste: implications for economically developing countries

Trade in hazardous waste has given rise to great concerns. One source of transboundary trade in hazardous waste is the ship-breaking industry. Though end-of-life vessels provide incentives to developing countries in the form of raw materials, these same developing countries are not only ill equipped to manage hazardous waste in an environmentally sound manner, but they also lack the resources to mitigate health impacts arising out of the handling of hazardous waste. These concerns of weaker economies have been addressed by the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and their Disposal. However, the shipping of vessels with hazardous waste for final disposal in developing countries continues. To illustrate the inequity involved in such negotiations, we present a case study of the French aircraft carrier “Le Clemenceau”, which was sent to a shipyard in Alang, India, for disposal. This vessel became the focus of attention given its transport of an unknown amount of toxic waste, including asbestos. Similarly, there are reports that large quantities of toxic waste are still being imported by India from countries that ban the use of this waste. The use, import, and export of these chemicals raise serious environmental and health concerns. This paper assesses the implications of shipping such hazardous waste to developing countries and emphasizes the need for promoting research to plug the gaps and for implementing stringent measures to check the trade in environmental pollutants.

Hazardous waste management system; standards applicable to generators of hazardous waste; state program requirements. Environmental Protection Agency. Final rule

On February 26, 1980 and May 19, 1980, under the Resource Conservation and Recovery Act (RCRA), the Environmental Protection Agency (EPA) published regulations establishing a system to manage hazardous waste. Those regulations allowed hazardous waste generators to accumulate hazardous waste on-site without obtaining a permit or meeting financial responsibility requirements if they shipped the waste off-site within 90 days. On November 19, 1980, the Agency published an interim final rule which expanded the scope of the provision to include generators who treat, store or dispose of hazardous waste on-site. The final rule published today retains this change. As a result of public comments, the Agency is making several changes to the interim final rule. These changes (1) Clarify that the provision is applicable to all generators, including those who accumulate hazardous waste for the purpose of use, reuse, recycling and reclamation, (2) remove the requirement for use of DOT containers, (3) revise the labelling and marking requirements for wastes accumulated in containers and tanks; and (4) allow an extension to the 90-day accumulation limit in certain circumstances.     

Theorizing waste in abortion and fetal ovarian tissue use.

This article explores the theoretical implications of the concept of waste as it specifically relates to arguments in favour of fetal ovarian tissue use as a source of donor eggs. The author begins by discussing medico-scientific constructions of women's reproductive bodies as wasteful. The article explores the works of Drucilla Cornell on bodily borders, Julia Kristeva on abjection, and Mary Douglas on pollution to develop a nuanced understanding of the relations between waste, women's reproductivity, and abortion in North American mainstream and medico-scientific cultures. This layered reading of waste and abortion deconstructs a significant assumption of arguments in favour of fetal ovarian tissue use as ethical--that such tissue is just "waste." The author suggests that theorizing waste this way may contribute to ethical analyses of uses of other reproductive materials (that is, embryos) that are supported, in part, by an assumption that those materials would otherwise be "wasted."     

Hazardous waste management; Environmental Protection Agency. Final rule

The Resource Conservation and Recovery Act, as amended, provides for the development and implementation of a comprehensive program to protect human health and the environment from the improper management of hazardous waste. A fundamental premise of the statute is that human health and the environment will best be protected by careful management of the transportation, treatment, storage, and disposal of hazardous waste, in accordance with standards developed under the Act. In today's Federal Register, the Environmental Protection Agency is publishing several documents setting in motion a series of events which will culminate in full implementation of the hazardous waste control program. This document sets forth definitions of words and phrases which appear in the subsequent Parts as well as general guidance for the use of these regulations and provisions which are generally applicable to all Parts.     

Hazardous waste management system standards for owners and operators of hazardous waste treatment, storage, and disposal facilities and EPA administered permit programs; hazardous waste permit program. Environmental Protection Agency. Interim final amendments to rule

On May 19, 1980, EPA promulgated regulations applicable to owners and operators of hazardous waste treatment, storage, and disposal facilities which prohibited the landfill disposal of most containerized liquid waste or waste containing free liquid on and after November 19, 1981. Further on June 29, 1981, EPA amended its hazardous waste management regulations so as to extend the compliance date of the restriction on the landfill disposal of containerized liquid ignitable wastes to coincide with the compliance data of the general restriction on landfill disposal of liquids. The Agency is today extending the compliance date on both these requirements until May 26, 1982, and, in a separate action, is proposing amendments to these restrictions. This extension of compliance dates is provided for the sole purpose of allowing time to complete the rulemaking action on today's proposed amendments. The Agency is also today exempting from the requirements of the hazardous waste management regulations, the acts of adding absorbent material to hazardous waste in containers and adding hazardous waste to absorbent material in a container, at the time waste is first placed in the container, in order to reduce the free liquids in a container.     

Container and waste pile standards for owners and operators of hazardous waste facilities: consolidated permit regulations--Environmental Protection Agency. Amendments to interim final rule

The Environmental Protection Agency (EPA) is today promulgating amendments to the hazardous waste management regulations regarding the management of hazardous waste in containers and piles and associated permit regulations (40 CFR Part 264, Subparts I and L, and Part 122, Subpart B). These amendments better tailor the standards to the particular type of hazard posed by specific situations. The standards for containers are amended to waive the containment system requirements for wastes that do not contain free liquids, provided that the wastes are protected from contact with accumulated liquid. The standards for waste piles are amended to waive the containment system requirements for wastes that do not contain free liquids, provided that the pile is protected from precipitation by a structure and from surface water run-on and wind dispersal of the waste by the structure or some other means. The Agency believes these amendments believes these amendments will not reduce the level of protection of human health and the environment.     

Hazardous waste,distributional conflict,and a trilogy of failures

Environmentally dangerous but profitable hazardous waste disposal is an instance of market failure. Tort law has failed as a social mechanism to sanction powerful corporations for such crimes against the environment. The federal Superfund hazardous waste cleanup program, a regulatory system created to fill this void, is also marked by failure. This article makes the case that the inability to resolve Superfund-engendered distributional conflicts has precluded the efficient and equitable outcomes that characterize a socially beneficial market, tort, or regulatory response. A political economy of regulation that links conflict, conflict resolution, and Superfund failure is examined.     

Guidelines for development and implementation of state solid waste management plans and criteria for classification of solid waste disposal facilities and practices--Environmental Protection Agency. Final rule

This rule modifies the Environmental Protection Agency's Guidelines for the Development and Implementation of State Solid Waste Management Plans (40 CFR Part 256) and the Criteria for the Classification of Solid Waste Disposal Facilities and Practices (40 CFR Part 257). The Guidelines are being amended to expand public participation opportunities in the planning process and provide for expedited approval of certain portions of the State plans. The Criteria are being amended to modify the groundwater, surface water and air protection criteria. EPA is taking this action as part of a settlement agreement reached with industrial groups which have challenged these regulations in Federal Court.     

Fatal and nonfatal poisoning by hydrogen sulfide at an industrial waste site

An adult man (A) entered a pit to collect seepage at an industrial waste site in Japan. As he suddenly lost consciousness, three colleagues (B, C, D) entered the pit to rescue him. All of these men lost consciousness in the pit. Two workers (A and B) died soon after the accident, one worker (C) died 22 days after the accident, and one worker (D) survived. Since hydrogen sulfide gas was detected in the atmosphere of the pit, gas poisoning was suspected. Toxicological analyses of sulfide and thiosulfate, a metabolite of sulfide, in blood and urine of the victims were made using the extractive alkylation technique combined with gas chromatography/mass spectrometry (GC/MS). Sulfide was detected in the blood of A and B at levels of 0.13 and 0.11 mg/L, respectively, somewhat higher than in healthy persons. Thiosulfate was detected in whole blood of deceased victims A and B, in the plasma of deceased victim C, at concentrations of 10.53, 4.59, and 4.14 mg/L, respectively. These values were similar to those found in fatal cases of hydrogen sulfide poisoning. Thiosulfate was not detected in the plasma of survivor D. With respect to urine samples, thiosulfate was the highest in the non-acute death victim C (137.20 mg/L), followed by that in the survivor D (29.34 mg/L), and low (0.90 mg/L) and not detected in the acute death victims, A and B, respectively. Based on these results, all four patients were victims of hydrogen sulfide poisoning. The concentrations of thiosulfate in blood and urine were more useful than that for sulfide for determining hydrogen sulfide poisoning. Thiosulfate in urine was the only indicator of hydrogen sulfide poisoning in the non-fatal victim.     

Wasting innovation: barriers to entry and European regulation on waste electronic equipment

The European Directive on Waste Electric and Electronic Equipment 2002/96/EC distorts incentives in regulated markets. Treatment of ‘historical waste’—i.e. products sold prior to 13 August 2005—is financed by all firms in the market at the time of disposal. This stimulates excessive pre-regulation output by incumbents for two reasons: a costs sharing effect and entry deterrence. Entry deterrence is achieved by raising the common costs of waste disposal. Entry is a main driver of innovation in the affected industries. The feasibility of a first best policy is discussed and an alternative rule superior to the status quo is presented.
