Oklahoma State University proposed Advanced Technology Research Center. Environmental Assessment

Description: The Department of Energy (DOE) has prepared an Environmental Assessment (EA) evaluating the construction and equipping of the proposed Advanced Technology Research Center (ATRC) at Oklahoma State University (OSU) in Stillwater, Oklahoma. Based on the analysis in the EA, the DOE has determined that the proposed action does not constitute a major federal action significantly affecting the quality of the human environment within the meaning of the National Environmental Policy Act (NEPA) of 1969. Therefore, the preparation of an Environmental Impact Statement is not required.

HEU to LEU conversion and blending facility: Metal blending alternative to produce LEU oxide for disposal

Description: US DOE is examining options for disposing of surplus weapons-usable fissile materials and storage of all weapons-usable fissile materials. The nuclear material is converted to a form more proliferation- resistant than the original form. Blending HEU (highly enriched uranium) with less-enriched uranium to form LEU has been proposed as a disposition option. Five technologies are being assessed for blending HEU. This document provides data to be used in environmental impact analysis for the HEU-LEU disposition option that uses metal blending with an oxide waste product. It is divided into: mission and assumptions, conversion and blending facility descriptions, process descriptions and requirements, resource needs, employment needs, waste and emissions from plant, hazards discussion, and intersite transportation.

Floodplain/wetlands assessment for the borrow areas for the restoration of the Weldon Spring Quarry, Weldon Spring Site, Missouri

Description: The US Department of Energy proposes to develop two soil borrow areas, 8.1 ha (20 acres) and 1.3 ha (3.1 acres) in size, near the Weldon Spring Site, Weldon Spring, Missouri. One wetland and portions of four others would be excavated during development of the borrow areas. These wetlands include palustrine emergent and palustrine forested wetland types and total 0.98 ha (2.4 acres). Hydrology and biotic communities may be altered in several wetlands located near the borrow areas. No long-term adverse impacts to floodplains are expected.

What is "Normative" at Cooling Water Intakes? Defining Normalcy Before Judging Adverse

Description: Judgments of adverse environmental impact from cooling water intake structures need to be preceded by an appreciation of what is normal. In its repo~ Return to the River, the Independent Scientd5c Group (now called the Independent Scientfilc Advisory Board) --the scientific peer review arm of the Northwest Power Planning Council-- advanced the notion of a "normative river ecosystem" as a new conceptual foundation for salrnonid recovery in the Columbia River basin. With this perspective, the sum of the best scientific understanding of how organisms and aquatic ecosystems function should be the norm or standard of measure for how we judge the effects of human activities on aquatic systems. ,For the best likelihood of recovery, key aspects of altered systems should be brought back toward nonnative (although not necessarily fully back to the historical or pristine state); new alterations should be judged for adversity by how much they move key attributes away from normative or what might be considered normal. In this presentation, I ask what "normative" is for the setting of cooling water intake structures and how this concept could help resolve long-standing disputes between groups interested in avoiding darnage to all organisms that might be entrained or impinged and those who take a more population or community perspective for judging adverse environmental impact. In essence, I suggest that if a water intake does not move the aquatic ecosystem outside the "normative" range, based on expressions of norrrdcy such as those discussed, then no adverse impact has occurred. Having an explicit baseline in normal or normative would place 316(b) analyses on the same conceptual foundation as 316(a) analyses, which strive to demonstrate the continuation of a balanced, indigenous community of aquatic organisms at the power station Iocation.

INTERNATIONAL COLLABORATION ON CO2 SEQUESTRATION

Description: The specific objective of our project on CO{sub 2} ocean sequestration is to investigate its technical feasibility and to improve the understanding of any associated environmental impacts. Our ultimate goal is to minimize any impacts associated with the eventual use of ocean carbon sequestration to reduce greenhouse gas concentrations in the atmosphere. The project will continue through March 31, 2002, with a field experiment to take place in the summer of 2001 off the Kona Coast of Hawaii. At GHGT-4 in Interlaken, we presented a paper detailing our plans. The purpose of this paper is to present an update on our progress to date and our plans to complete the project. The co-authors of this paper are members of the project's Technical Committee, which has been formed to supervise the technical aspects and execution of this project.

INTERNATIONAL COLLABORATION ON CO2 SEQUESTRATION

Description: The ocean represents the largest potential sink for anthropogenic CO{sub 2}. In order to better understand this potential, Japan, Norway, and the United States signed a Project Agreement for International Collaboration on CO{sub 2} Ocean Sequestration in December 1997; since that time, Canada and ABB (Switzerland) have joined the project. The objective of the project is to investigate the technical feasibility of, and improve understanding of the environmental impacts from, CO{sub 2} ocean sequestration in order to minimize the impacts associated with the eventual use of this technique to reduce greenhouse gas concentrations in the atmosphere. The project will continue through March 31, 2002, with a field experiment to take place in the summer of 2000 off the Kona Coast of Hawaii. The implementing research organizations are the Research Institute of Innovative Technology for the Earth (Japan), the Norwegian Institute for Water Research (Norway), and the Massachusetts Institute of Technology (USA). The general contractor for the project will be the Pacific International Center for High Technology Research in Hawaii. A Technical Committee has been formed to supervise the technical aspects and execution of this project. The members of this committee are the co-authors of this paper. In this paper we discuss key issues involved with the design, ocean engineering, measurements, siting, and costs of this experiment.

China energy, environment, and climate study: Background issues paper

Description: The total costs and impacts of expanding energy use in China will depend, in part, on a number of important factors, an understanding of which is vital for China's policy-makers. These issues include the additional environmental and public health impacts associated with energy use, the economic costs of infrastructure expansion to meet growing energy needs, and the potential role that renewable energy technologies could play if pushed hard in China's energy future. This short report summarizes major trends and issues in each of these three areas.

Naval Reactors Facility environmental monitoring report, calendar year 1999

Description: The results of the radiological and nonradiological environmental monitoring programs for 1999 at the Naval Reactors Facility (NRF) are presented in this report. The results obtained from the environmental monitoring programs verify that releases to the environment from operations at NRF were in accordance with Federal and State regulations. Evaluation of the environmental data confirms that the operation of NRF continues to have no adverse effect on the quality of the environment or the health and safety of the general public. Furthermore, a conservative assessment of radiation exposure to the general public as a result of NRF operations demonstrated that the dose received by any member of the public was well below the most restrictive dose limits prescribed by the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE).

Measures of the Environmental Footprint of the Front End of the Nuclear Fuel Cycle

Description: Previous estimates of environmental impacts associated with the front end of the nuclear fuel cycle have focused primarily on energy consumption and CO2 emissions. Results have varied widely. Section 2 of this report provides a summary of historical estimates. This study revises existing empirical correlations and their underlying assumptions to fit to a more complete set of existing data. This study also addresses land transformation, water withdrawals, and occupational and public health impacts associated with the processes of the front end of the once-through nuclear fuel cycle. These processes include uranium mining, milling, refining, conversion, enrichment, and fuel fabrication. Metrics are developed to allow environmental impacts to be summed across the full set of front end processes, including transportation and disposition of the resulting depleted uranium.
