The U.S. Department of Energy’s Oak Ridge Office of Environmental Management has responded to a recommendation made earlier this year by the Oak Ridge Site Specific Advisory Board.

In May, the federally appointed citizens’ panel recommended that DOE conduct additional groundwater studies to address any potential offsite migration of chemicals or radioisotopes from DOE’s Oak Ridge Reservation. The recommendation focuses on developing information that fosters a better understanding of potential impacts of groundwater contamination related to risk mitigation, groundwater remediation, and long-term stewardship.

In 2013, DOE, the Environmental Protection Agency, and the Tennessee Department of Environment and Conservation held a series of workshops to prioritize groundwater pathways on the ORR. Together the agencies created a groundwater strategy document that described the potential for releases from waste disposal sites and storage areas. The document also prioritized known groundwater plumes, concentration of contaminants, contaminants of concern, and potential health risks. [Read more…]

DOE responds to SSAB’s waste disposal recommendation

The U.S. Department of Energy’s Oak Ridge Office of Environmental Management has responded to a recommendation made earlier this year by the Oak Ridge Site Specific Advisory Board.

In May, the federally appointed citizens’ panel recommended that DOE continue to plan for additional on-site waste disposal capacity on the DOE Oak Ridge Reservation, or ORR, for low-level radioactive and chemically hazardous waste.

DOE currently operates the Environmental Management Waste Management Facility, or EMWMF, a low-level radioactive waste disposal facility in Bear Creek Valley near the Y-12 National Security Complex. When the facility began accepting waste in 2002, it was expected to handle all projected low-level waste from cleanup operations on the ORR. However, with the amount of demolition and work left to complete, EM requires additional disposal capacity onsite.

DOE has conducted a study to develop, screen, and evaluate alternatives for an additional waste disposal facility, with a working name of EM Disposal Facility, or EMDF. ORSSAB’s recommendation encouraged the agency to continue working toward adding disposal capacity and proposed recommendations for a new facility.

The ORSSAB encouraged DOE to minimize the need for additional on-site capacity when possible. In its response, DOE said it was examining the final cover design of the EMWMF to allow for extended capacity. The waste acceptance criteria for other so-called “sanitary landfills” on Chestnut Ridge are being evaluated for possible modifications to allow a wider variety of waste. [Read more…]

DOE commits to three-year, $4.5 million groundwater study in Oak Ridge

Daniel Goode and SSAB Groundwater Strategy Presentation

Daniel J. Goode, a research hydrologist for the U.S. Geological Survey, briefs members of the Oak Ridge Site Specific Advisory Board on a new groundwater strategy for the Oak Ridge Reservation.

The U.S. Department of Energy has agreed to spend $4.5 million during the next three years to study groundwater contamination on the Oak Ridge Reservation.

The reservation includes three federal sites—East Tennessee Technology Park, Oak Ridge National Laboratory, and Y-12 National Security Complex—that have been involved in missions ranging from scientific research to uranium enrichment to nuclear weapons work. That work has sometimes included the use of hazardous substances such as mercury and technetium-99, a slow-decaying radioactive metal.

The $4.5 million in funding will help implement a new groundwater strategy developed by DOE with help from the Tennessee Department of Environment and Conservation and the U.S. Environmental Protection Agency.

The strategy, which was presented to the Oak Ridge Site Specific Advisory Board in November, will help guide future cleanup decisions, said Sue Cange, deputy manager for environmental management in DOE’s Oak Ridge Office. [Read more…]

A citizens’ panel will discuss a strategy document tonight that outlines possible solutions for managing contaminated groundwater on the federal reservation in Oak Ridge.

It’s the focus of a 6 p.m. meeting of the Oak Ridge Site Specific Advisory Board. The strategy document was developed to address problems with contaminated groundwater on the U.S. Department of Energy’s Oak Ridge Reservation.

The meeting is in the DOE Information Center in the Office of Science and Technical Information on Oak Ridge Turnpike. The public is welcome to attend. OSTI is between Science.gov Way and Melton Lake Drive. [Read more…]

There is great uncertainty on what the looming federal budget cuts will be and what effect they will have on funding for the U.S. Department of Energy’s Environmental Management, or EM, program at the Oak Ridge Reservation. We can be confident that budget cuts are coming. It is going to take a coordinated effort on the part of the DOE-Oak Ridge EM, regulators, and stakeholders to minimize the impact on current and future remediation projects, and on the men and women who carry out this work.

Right now DOE-EM is operating on a temporary six-month budget. This budget covers just the first half of Fiscal Year 2013 and is based on half of the FY 2012 budget. We should know soon how changes in the federal budget affect Oak Ridge EM for the second half of 2013. This still leaves the 2014 budget in question. [Read more…]
