The Office of Technology Assessment was asked to study the Nation’s oil spill clean-up capabilities and to assess the technologies for responding to such catastrophic spills in the future.

This paper presents the status of national efforts to cleanup dioxin-contaminated sites and the technologies that have been used, proposed, and researched. It covers thermal and nonthermal treatment techniques as well as approaches such as stabilization and storage. It discusses the development of these technologies as well as advantages and disadvantages of their use.

The paper has six major purposes, in order to analyze the uses of tests used in vocational programs, particularly those designed to measure broad technical skills, identify trends in vocational assessment, and identify policy issues relevant to improving test development and quality.

This background paper, which describes the state-of the- art of identifying substances that can harm the immune system, represents one response to the committee’s request. Chapter 2 provides basic information about the principal components of the immune system and the general consequences that stem from perturbations to it. Chapter 3 describes methods for evaluating chemical immunotoxicity and reports on some known or suspected immunotoxicants. Chapter 4 summarizes Federal research and regulatory activities related to immunotoxicity.

This report describes, documents, and analyzes available data about two key waste management problems at the Department of Energy Weapons Complex—those of high-level radioactive waste and transuranic waste. The paper is organized in two chapters—” Chapter 1: Managing High Level Waste’ and ‘Chapter 2: Managing Transuranic Waste. ” Each chapter contains a summary overview followed by a discussion and analysis of important areas in the waste management problem that the DOE faces at present and in its future operations.

This OTA Background Paper presents the results of a survey of 1,500 U.S. companies, the 50 largest utilities, and the largest unions. The survey was designed to obtain information about the types of medical monitoring and screening done in the United States and the extent of their use. OTA finds that virtually all large U.S. employers use some of these tests.

This background paper discusses the legacy of 40 years of U.S. university/AID collaboration, and examines new opportunities for U.S. university participation in development assistance.

This paper presents results from a 1991 OTA survey of 431 genetic counselors and nurse geneticists. It was conducted to better understand the environment in which the average genetic counselor or nurse in genetics works, to describe the infrastructure and tools available to these professionals, to assess the state of practice in the provision of cystic fibrosis (CF) carrier screening, and to evaluate their attitudes regarding CF carrier screening.

This background paper describes results from a 1991 OTA survey of U.S. health insurers’ attitudes toward genetic tests and genetic information— both how they currently view information from various sources (e.g., genetic tests, other medical tests, or family histories) in underwriting decisions and how they might reimburse consumers for genetic tests. It also reports data on the role health insurers expect genetic tests and genetic information will play in their business practices over the coming decade.

This Background Paper examines whether the agencies responsible for administering Federal environmental and health and safety laws have taken this concern for respiratory health to heart. This paper provides a partial response to the committees’ request for an assessment of noncancer health risks in the environment and follows OTA’s previous work on carcinogenic, neurotoxic, and immunotoxic substances.

This background paper first describes the structure and management of the French defense-industrial base and then reviews a variety of strategies the French Government and industry are pursuing to rationalize the base, while preserving key technological assets and strengthening the competitive position of French defense contractors in world markets.

This background paper examines wastes generated by industrial activities that play a dominant role in our national economy-oil and gas production, mining and mineral processing, coal combustion, and manufacturing. In previous reports on municipal solid waste and medical waste, OTA examined other solid wastes not classified as hazardous.

This background paper briefly describes the Army’s chemical weapons destruction program, discusses the factors that could affect a decision to develop alternatives, discusses the alternatives, and illustrates the difficulty of gaining public acceptance of complex technical systems.
