Intermediate-level waste transfer line decommissioning project. Final report
The Intermediate-Level Waste (ILW) transfer line at Oak Ridge National Laboratory (ORNL) was an integral part of the liquid radioactive waste disposal system, operating from 1952 until 1975. This line was used to transport ILW from the waste processing facilities in the Bethel Valley area at ORNL to final disposal sites in the adjacent Melton Valley. During the history of pipeline operations, approximately 45 million gallons of liquid waste, containing over 1.5 million curies of mixed fission products, were transferred through the line to waste disposal trenches and to the ORNL hydrofracture facility. Use of the line was discontinued in 1975 when a new, doubly-contained line was installed to service the expanded hydrofracture program. Since 1976, the ILW line has been under the control of the ORNL Surplus Facilities Management Program (SFMP). Due to the presence of contaminated soil at two former leak sites along the line, and the potential for radionuclide migration from that portion of the abandoned line that traverses White Oak Creek and the floodplain, decommissioning of the ILW line was given a high priority by the ORNL SFMP. In 1979, plans were initiated for corrective action along those portions of the line. The decommissioning activities havemore » now been completed, with the abandoned line being placed in a condition that significantly reduces the hazards associated with it. The portion of the line in the White Oak Creek floodplain was removed, and the two leak sites entombed. This report presents the results of the ILW line decommissioning project, outlining the scope of the effort, describing the decommissioning experiences, and summarizing the project costs and schedules. 14 references, 30 figures, 3 tables.« l

Radon and radon daughter measurements at and near the former Middlesex Sampling Plant, Middlesex, New Jersey
The results of the radon and radon daughter measurements made to date (1978) at the Middlesex Sampling Plant in Middlesex, New Jersey, are presented in this report. These measurements were one portion of a more comprehensive radiological survey conducted at this site and the surrounding area from 1976 to 1978. The surveyed property served as a uranium ore sampling plant during the 1940's and early 1950's and as a result contains elevated levels of surface an subsurface contamination. On-site indoor radon daughter and radon concentrations exceeded both the US Surgeon General Guidelines and the Nuclear Regulatory Commission's maximum permissible concentration limits for radon (10 CFR Part 20) in all structures surveyed. Off-site structures showed concentrations of radon and radon daughters at or only slightly above background levels, except for one site where the radon levels were found to be above the 10 CFR Part 20 guidelines. Outdoor radon ad radon daughter concentrations, measured both on and off the site, were well below the guidelines, and the data give no indication of significant radon transport from the site

ORNL long-range environmental and waste management plan
This report, the ORNL Long-Range Environmental and Waste Management Plan, is the annual update in a series begun in fiscal year 1985. Its primary purpose is to provide a thorough and systematic planning document to reflect the continuing process of site assessment, strategy development, and planning for the current and long-term control of environmental issues, waste management practices, and remedial action requirements. The document also provides an estimate of the resources required to implement the current plan. This document is not intended to be a budget document; it is, however, intended to provide guidance to both Martin Marietta Energy Systems, Inc., and the US Department of Energy (DOE) management as to the near order of magnitude of the resources (primarily funding requirements) and the time frame required to execute the strategy in the present revision of the plan. As with any document of this nature, the near-term (one to three years) part of the plan is a pragmatic assessment of the current program and ongoing capital projects and reflects the efforts perceived to be necessary to comply with all current state and federal regulations and DOE orders. It also should be in general agreement with current budget (funding) requests and obligations for these immediate years. 55 figs., 72 tabs

ORNL long-range environmental and waste management plan: Program overview and summary
The primary purpose of this report is to provide a thorough and systematic planning document to reflect the continuing process of site assessment, strategy development, and planning for the current and long-term control of environmental issues, waste management practices, and remedial action requirements. The docuemnt also provides an estimate of the resources required to implement the current plan. This document is not intended to be a budget document: it is, however, intended to provide guidance to both Martin Marietta Energy Systems, Inc., and the US Department of Energy (DOE) Management as to the near order of magnitude of the resources (primarily funding requirements) and the time frame required to execute the strategy in the present revision of the plan. The near-term (one to three years) part of the plan is a realistic assessment of the current program and ongoing capital projects and reflects the efforts preceived to be necessary to comply with all current state and federal regulations and DOE orders. It also should be in general agreement with current budget (funding) requests and obligations for these immediate years. Beyond the immediate time frame, the document reflects the strategy and the project and funding estimates as a snapshot at the time of publication. Annual revision will reflect the continuing evoltuion and development of environmental and waste management processes, characterizations, remedial actions, regulations, an strategies for the establishment and conduct of a comprehensive environmental and waste management program. 15 figs., 10 tabs
