(Story on Page 8) February 1991 Letter from DOE's Assistant Manager for Environmental Restoration and Waste Management As the new year begins, I want to emphasize our continued commitment to clean up the 40-year legacy from past operations and to further improve the waste management practices on the Oak Ridge Reservation. Last year considerable progress was made in these areas, including sampling along East Fork Poplar Creek, completion of cleanup at seven hazardous waste sites at the Y-12 Plant, holding a public information meeting, continued reduction of waste generation rates, and opening an Information Resource Center. Additionally, detailed sampling activities were continued order to better understand the in environmental contamination and to determine feasible cleanup options. Bill Adams Efforts this year will focus on the start of full-scale operations of the TSCA Incinerator, work at the K-25 drum storage yard to achieve compliance with environmental laws, and actions to further reduce the potential for radioactive contamination leaving the Reservation through White Oak Creek. The sampling and investigation activities will also be expanded. I appreciated the interest shown by the community in our public meeting last October. We will continue to do our part to keep you informed and involved in our cleanup and waste management activities. Sincerely, ------- 2 Public Meeting Held on Site Specific Plan for Oak Ridge Reservation \ JL -A. bout 350 people attended the public meeting on the Site Specific Plan for cleanup and waste management activities on the Oak Ridge Reservation held by the U. S. Department of Energy (DOE) on October 16, 1990, at the Pollard Auditorium in Oak Ridge. The meeting provided a forum for DOE to discuss cleanup and waste operations plans for the Oak Ridge facilities and for citizens to share their concerns and provide comments. The evening's activities included an informal poster session, formal presentations, and a question-and-answer session. Displays of each of the local DOE facilities (Oak Ridge National Laboratory, the Y-12 Plant, and the K-25 site) and the off-site environmental restoration programs were provided. Environmental restoration and waste management personnel from DOE Oak Ridge Operations Office and their contractor staff were available to talk informally with members of the public about waste management and cleanup activities. Information materials about the programs were available (see page 11 for a list of available fact sheets). In the formal presentations, Bill Adams, DOE Oak Ridge Operations assistant manager for Environmental Restoration and Waste Management, introduced DOE officials who discussed the program. DougUnderwood, deputy director of the Waste Management Division, described the DOE Five-YearPlan. Bob Sleeman, director of the Environmental Restoration Division, spoke about activities being undertaken in the Environmental Restoration Program. Larry Radcliffe, director of the Waste Management Division, outlined the various waste disposal activities being conducted. Dr. Robert Smallridge, superintendent of Oak Ridge Schools, served as moderator for the question-and- answer period following the formal presentations. Members of the public had an opportunity to make formal comments for the record on the Site Specific Plan. Similar meetings are planned in the future. DOE encourages the citizens of Oak Ridge and surrounding communities to attend. F JL ron Remedial Action Plan Scheduled for 1991 rom June 1982 to late 1985 approximately 30,000 drums of low-level radioactive solid waste and 288 boxes of low-level scrap metal were shipped from the United Nuclear Corporation facility in Rhode Island to the Y-12 Plant. The material is contaminated with small amounts of uranium and larger amounts of nitrates, a chemical byproduct of uranium processing. Upon arrival at the Y-12 Plant in Oak Ridge, a dozen drums were found to have been damaged by punctures or tears in the metal. The contents of the most severely damaged drums were transferred to new drums before being placed in a storage area. All of the drums are temporarily stacked in a trench. Plastic sheeting helps protect the drums from exposure to rain. The site has been monitored and, to date, no contaminants from the drums or boxes have entered the groundwater. In accordance with environmental regulations, investigators are performing feasibility studies, which identify and compare alternatives for closing a waste site (see fact sheet, OER-0006 listed on page 11). Results of the 'feasibility studies will be used to develop a proposed draft Remedial Action Plan. The Remedial Action Plan for cleanup of the storage site is scheduled for public review and comment during 1991. A brief analysis of the proposed plan will be published with a public notice of availability. There will be an opportunity for a public meeting and for members of the public to comment on the proposed plan. After thorough consideration, a record of decision will be published ------- 3 Information Resource Center Opens D rOE has established a permanent home for the Information Resource Center that contains the Administrative Record and other materials related to the Oak Ridge Reservation environmental cleanup. The Center is located at the former Ridge Theater at 105 Broadway Avenue, near the Jackson Square Shopping Center. The building was renovated for its new use, and parking is available along Broadway Avenue. Until recently, the Information Resource Center was temporarily housed in offices of DOE's Technical Support Contractor, Lee Wan & Associates. The new Center will provide office and storage space, and house the many documents relating to cleanup activities. Information Resource Center Hours: Monday, Wednesday, and Friday 9 a.m. - 5p.m. Tuesday and Thursday 9 a.m.-7 p.m. Saturday 9 a.m. -1p.m. Samples Collected from White Oak Creek Embayment An open house at the Information Resource Center is planned for February 26, 1991. As required by EPA regulations, the Oak Ridge Information Resource Center will contain documents related to the Oak Ridge Reservation cleanup activities and the Superfund Program in general. The Center houses the administrative record file, which is an ongoing collection consisting of all documents used by DOE to make decisions in their cleanup of the Oak Ridge Reservation and certain off-site locations, including separate records from the Elza Gate restoration project near the eastern city limits of Oak Ridge. Printed materials such as program publications, fact sheets, newsclips and background documents also will be available for review. Personnel will be on hand to assist visitors with their information searches. Most often-requested and newly released documents will be on display and available upon request Researchers have collected samples of creek sediments below White Oak Creek Dam to determine concentration of contaminents. An open house for the public is planned for February 26,1991, from4:00-7:00p.m. An announcement will be . „ . .... ... . . „ . . , , 1 , .,,, , ' Cesium-137 is a radioactive isotope thathistoncallyhas been produced made in all local area newspapers and will be distributed wsearch reQdor op(:ml]ons at Qak Ridge NationaI to everyone on the mailing list for this Update. §g (ORNL). 9HSHHH Surface sediment samples collected from the lower portion of White Oak Creek Embayment during the summer of 1990 indicated higher than expected levels of cesium-1371 contamination in the top two to four inches of the sediment. As a result of these findings, an accelerated sampling effort has been initiated to determine the extent of the contamination and to prevent the transport of contaminated sediment into the Clinch River. These recent findings, however, do not indicate any increased health risk to the public. ------- 4 Site Investigation Planned for ORAU's South Campus Facility T JL. he Oak Ridge Associated Universities (ORAU) is a familiar institution to those in the Oak Ridge Area. As a private, non-profit association of 59 colleges and universities, ORAU conducts research and education programs in the areas of energy, health, and the environment. ORAU serves DOE, its member institutions, and other private and government organizations. One ORAU site is the South Campus Facility (SCF) located near Freels Bend, just off the Clinch River, on Oak Ridge Reservation lands. The site may be contaminated with unknown types and amounts of hazardous wastes as a result of past research activities. Evolution of the South Campus Facility The South Campus Facility began as a research facility in 1945 under the Atomic Energy Commission and the University ofTennessee. Researchers studied the effects of accidental irradiation of cattle which occurred during the testing of the first atomic bomb in New Mexico. Subsequently, the name of the laboratory was changed to the Comparative Animal Research Laboratory (CARL). Research conducted by CARL focused on the effects and metabolism of toxic materials, especially those related to energy production, on different animals. CARL became a division of ORAU in 1981. Research is no longer conducted at the facility. Possible Contamination It is suspected that some of the substances used in research contaminated the facility. These substances include radionuclides, wastewater sludge, and organic compounds such as solvents and petroleum hydrocarbons. Other contaminants may alsobe present. To determine whether the contamination warrants a full-scale cleanup under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), as amended by the Superfund Amendments and Reauthorization Act, 1986, a site investigation is planned for 1991. This investigation will help clarify just what is present, whether the levels of waste are significant, whether off-site releases have occurred, and whether the contamination requires further investigation. The South Campus Facility, near Freels Bend, may be contaminated as a result of past practices. Existing information on the contamination has been limited to results from on-site sampling. Several previous assessments of the facility suggest possible contamination.1 A total of 16 environmental samples will be collected. These will aid in identifying migration pathways and any source areas of contaminants which may exist at the site. A review of facility records will also be performed. The site investigations are expected to be completed during 1991. DOE will continue to inform the public of developments through news releases and through articles in future issues of the Environmental Update. 11 'A DOE report in 1987, entitled Phase 1 Installation Assessment, identified five potential CERCLA sites at ORAU. A Resource Conservation and Recovery Act Facility Assessment, completed in March 1987, listed the same facility. A scoping survey under the ORAU Remedial Action Program resulted in a Preliminary Assessment that recommended performance of investigations under ------- 5 E Environmental Monitoring and Sampling at East Fork Poplar Creek and the Sewerline Beltway I ast Fork Poplar Creek is currently being studied to determine the type and extent of contamination and to help DOE develop appropriate cleanup plans. The Creek contains mercury and traces of other contaminants as a result of off-site releases from the Y-12 Plant, located on the Oak Ridge Reservation. Field activities to obtain soil and water samples began in 1990. Records from earlier studies are also being reviewed. In the early 1980s, East Fork Poplar Creek floodplain soils were used as excavation fill for a new sewerline in Oak Ridge. The contaminated soil thus contaminated the sewerline area, which is also being included in the study with the East Fork Poplar Creek floodplain. Jefferson and Robertsville Junior High Schools and the Oak Ridge Civic Center, once contaminated by the fill dirt, were remediated in 1984. Samplingforthe sewerline is planned for 1991. Environmental work at East Fork Poplar Creek is governed primarily by three federal laws. These laws are: the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), which is also known as Superfund; the Resource Conservation and Recovery Act (RCRA); and the National Environmental Policy Act (NEPA). Investigations, analyses and documentation for these laws will be combined and integrated. (These laws are explained in greater detail in the fact sheet, "Principal Laws and Regulations Affecting the Cleanup Program," which can be ordered by using the form on page 11.) Currently, a Remedial Investigation/Feasibility Study (RI/FS), required by CERCLA, is underway at East Fork Poplar Creek. The purpose of the remedial investigation is to gather all existing data on the Creek and perform field studies to gather new data that are needed. In order to select the best cleanup option, DOE must evaluate the ecological and human health risks posed by the site in its current condition (a "baseline" risk assessment) and then evaluate how the risk will change under various cleanup options. The feasibility study will discuss all the alternatives that are being considered and the pros and cons of each alternative in terms of effectiveness in reducing the human health risk, feasibility, cost, and compliance with applicable laws and regulations. The feasiblity study report will be combined with the Environmental Impact Statement, which is required by NEPA. By this means, potential effects on the environment will also be considered. Following the fi I Studies of East Fork Poplar Creek will be used to select the best overall cleanup alternative. review of alternatives, a remedial action plan will be selected. Near-Term Activities Activities up to September 1991 will focus on the field investigation portion of the study, as well as performing the preliminary screening of the feasibility of possible cleanup alternatives. The remedial investigation is divided into two parts, or phases. The first phase (1A) explores the nature or type of contamination (i.e., what contaminants are of concern) by looking at a broad range of possible contaminants. The second phase (IB) concentrates on defining the extent of contamination and the risk associated with the different contaminants and different concentrations of those contaminants at various locations. First Phase Sampling Field work First Phase Sampling began in October 1990. Preliminary results are expected in early 1991. Water and soil samples will be screened for a variety of contaminants. Data from this first phase will be used to develop the sampling plan for the next phase. ------- 6 Environmental Monitoring and Sampling at East Fork Poplar Creek and the Sewerline Beltway (continued from page 5) For East Fork Poplar Creek and its floodplain, the first phase involves installing, developing, and sampling 11 new groundwater wells; redeveloping and sampling 10 existing wells; sampling the floodplain soil; and sampling the surface water and sediment of East Fork Poplar Creek. Twenty tributaries to the East Fork Poplar Creek watershed will be sampled to determine if there are other sources of contaminants besides those from Y-12. In addition, storm water sampling will be conducted to help assess the physical transport of contaminants during heavy rainfall. Researchers are also sampling Hinds Creek near Norris, Tennessee, to find out what the Creek would be expected to contain under natural conditions. Soil, sediment, and surface water will be collected there. Sampling activity will be conducted all along the floodplain but will be most noticeable to the public near the DOE Atmospheric Diffusion and Dispersion Laboratory, Brunner Center, and the Jefferson tennis courts. Second Phase Sampling This sampling is scheduled to begin in April 1991. It will include the sewerline beltway as well as East Fork Poplar Creek. To help researchers obtain information more quickly, field screen techniques probably will be used. For example, x-ray fluorescence could be used to find mercury or lead, and portable test units could examine gas vapors to identify the presence of toxic chemicals. In addition, workers will look for "families" of similar contaminants using one or two key contaminants as indicators. The results of field tests will be followed up with laboratory verification to assure their accuracy. For the remainder of fiscal year 1991, the study team will initiate a floodplain and wetlands assessment, complete laboratory and data analysis of first phase sampling, complete the preliminary risk assessment, and initiate the second phase of sampling. As required by EPA regulations, the study team will prepare a Preliminary Site Characterization Report, a Phase IB Sampling and Analysis Plan, a Draft Initial Screening of Alternatives Report, and a Draft RCRA Facility Investigation/Remedial Investigation Report. Community relations and technical staff will arrange to meet with property owners along East Fork Poplar Creek to discuss sampling results as they become (continued on page 7] Wells are being drilled to determine the presence and concentrations of mercury and other contaminants in groundwater. Portable test units are used to detect toxic gas vapors such as ------- 7 A dosimeter is used to delect trace amounts of radioactive elements in floodplain soil. Environmental Monitoring and Sampling (continued from page 6) available. Questions will be answered and input on preferred alternatives will be solicited. Members of the public will have a variety of opportunities, both formal and informal, to be involved in decisions about East Fork Poplar Creek. Citizens can learn about activities and progress through the Information Resource Center (see article on page 3), through news releases and public notices in the media and Environmental Update, and through direct contact with DOEstaff. Public meetings, such as the meeting held in October 1990, will allow all interested persons to hear presentations about site developments, raise issues, and ask questions in a public forum. Formal opportunity will be provided for public comment on the draft Feasibility Study/Environmental Impact Statement, which is currently scheduled for publication in 1992. Samples Collected from White Oak Creek Embayment (continued from page 3) White Oak Creek is the primary surface water drainage for Oak Ridge National Laboratory (ORNL). The embayment is located between White Oak Lake Dam and the Clinch River. The results of recent sampling of the embayment indicate that the near-surface sediment contamination resulted from past releases from ORNL.2 Apparently, sediment erosion within the lower embayment has resulted in the exposure of the older, more contaminated sediment layer. Clinch River. Completed design plans are expected from the Army Corps of Engineers in February 1991. Completion of the sediment-control structure is scheduled for this fiscal year (before September 30, 1991). Information on the activities on White Oak Creek Embayment will be made available through the local media and publications distributed by DOE. "It is important to realize that the location of cesium-13 7 we have observed in the embayment is not the result of deeply buried contaminants moving up to the sediment surface," said Bruce Kimmel, Energy Systems coordinator for the expanded effort on the embayment. "Instead, it is the result of the gradual erosion and downstream movement of sediment in a very small, shallow (2 to 10 feet in depth) body of water that is subject to both inflowing and outflowing water." In cooperation with the Stale of Tennessee, the Environmental Protection Agency, U.S. Army Corps of Engineers and the Tennessee Valley Authority, DOE and Martin Marietta Energy Systems have determined that construction of a sediment retention structure is the preferred approach to controlling the contaminated sediments and preventing them from moving into the Cleanup researchers discuss the analysis of a sediment sample from the While Oak Creek Embayment. 'Recent data indicate that no new large release of cesium-137 has occurred from White Oak Ijake. Also, samples taken from the Clinch ------- 8 Public Comment Received on Proposed Cleanup Action at Elza Gate Site O December 6, the DOE Oak Ridge Operations issued a public notice announcing for public comment on Engineering Evaluation/Cost Analysis (EE/CA) for cleanup of a portion of the Elza Gate site in Oak Ridge. The document was available for public review at the DOE Information Resource Center (see article on page 3). The comment period closed on January 4, 1991. Comments are currently being reviewed in anticipation of preparation of a responsiveness summary documenting DOE's response to each comment. The responsiveness summary also will be made available in the Information Resource Center. The Elza Gate site, now known as Melton Lake Industrial Park, is located on the east end of Oak Ridge. Contamination present in the soil under one of five on- site concrete pads, referred to as Pad 1, includes uranium, radium, and thorium. The Elza Gate site originally consisted of five warehouses and possibly other smaller structures which were used to store high-grade uranium ore and processing residues as part of the Government's early nuclear energy program. DOE predecessor agencies also used the site to store various electrical equipment. After decontaminating the site to levels acceptable at the time (early 1970s), the property was sold to the City of Oak Ridge and eventually to a company which plans to develop the site as an industrial park. The Engineering Evaluation/Cost Analysis summarizes the analysis of cleanup alternatives and rationale for DOE's remedial action preference for Pad 1. Options evaluated for control of the contaminated soil underneath the Pad included the removal of the contaminated soil by either excavation or treatment, followed by an interim storage method. Based on available information, DOE's preferred alternative for management of the waste is removal by excavation of the contaminated materials, and interim storage. This action would include breaking up the concrete pad, which covers approximately 25,000 square feet, removing the contaminated concrete and soil, and storing it onsite until an appropriate storage location on the DOE Oak Ridge Reservation can be designated. Additional action will be required to remediate the remainder of the Elza Gate site. This action will be the subject of a separate Engineering Evaluation/Cost Analysis expected to be published during the spring of 1991 when DOE plans to begin implementation of the complete site cleanup. DOE will also consider combining the cleanup of Pad 1 with this more comprehensive plan. First Issue of Environmental Update Available The first issue of Environmental Update from September 1990, along with current Fact Sheets on Environmental Restoration at the Oak Ridge Reservation, is available by using the order form on page 11. Topics in the first Update include: • Department of Energy plans for environmental restoration of the Oak Ridge Reservation as part of the National Priorities List. • Technical progress on the restoration of key sites and associated off-site areas of the Oak Ridge Reservation. • Information on the Technical Assistance Grant Program available to community groups affected by hazardous waste ------- 9 Oak Ridge Reservation Environmental Report for 1989 D ¦flL^^OE has issued the two-volume Oak Ridge Reservation Environmental Report for 1989, the nineteenth in an annual series that began in 1971. The Report describes the results of a comprehensive year- round program to monitor the environmental effects resulting from operations of the Oak Ridge facilities. Groundwater, surface waters, soil, air quality, vegetation, wildlife, and human health are all considered. The Oak Ridge monitoring program is important for ensuring compliance with state and federal regulations for safe industrial operations. The monitoring also provides a standard for measuring progress in environmental practices. DOE is working with the Tennessee Department of Health and Environment and the Environmental Protection Agency to ensure the validity of the data. Environmental monitoring is part of a continuous process to identify releases of contaminants and compare releases to applicable environmental standards. The Report documents waste emissions, both from the sources and as monitored in the external environment. Its ultimate goal is to identify potential pathways to humans and the potential impacts for human health and environmental quality. The monitoring system includes over 850 on-site wells, over 400 discharge and surface-water-sampling stations, and 96 on-site exhaust-stack monitors for detecting radionuclide releases. Air, waterways, soils, fish, sediments, and dairy milk were monitored or sampled. The Oak Ridge Reservation Environmental Report for 1989 summarizes the environmental impacts both on and off the reservation and is available for review at the Information Resource Center, 105 Broadway Avenue, Oak Ridge. Atmospheric Releases As noted in the Report, releases of contaminants to the atmosphere during 1989 were within air quality standards, both federal and state, at all sites. Uranium emissions were less than those measured in 1988. Sulfur dioxide emissions, fluoride, and suspended particulates were also within standards. Surface Water Discharges Surface water discharges from White Oak Lake showed an increase in tritium, strontium, cobalt, and cesium contamination. While measured concentrations of these metals decreased from 1985 to 1988, heavier rainfall in 1989 flushed these metals into surface waters, causing an increase in 1989. Aquatic Life Bluegill from the Clinch River are used to monitor the effects of contamination on aquatic wildlife. Over the five-year period ending in 1989, mercury levels decreased 40 percent, polychlorinatedbiphenyls[PCBs) decreased 90 percent, cobalt-60 decreased 82 percent, cesium-137 decreased 80 percent, and strontium-90 decreased nearly 90 percent. Sediments Sediments from the Clinch River, near the K-25 Site, show that levels of uranium and mercury levels have changed little in five years, while levels of nickel, chromium, and aluminum have generally decreased. / Federal Facility Agreement Public Meeting February 5, 6 p.m. Pollard Auditorium Oak Ridge Associated Universities The Environmental Protection Agency recently held a public meeting to obtain community comments on the Federal Facility Agreement that guides environmental restoration activities at Oak Ridge. The agreement has been negotiated between DOE. the Environmental Protection Agency (Region IV), and the State of Tennessee Department of Health and Environment. The agreement sets priorities, assigns agency roles and responsibilities, and establishes procedures for document review and interaction among the agency officials.
