U.S. Department of Energy’s (DOE) Fernald Site

The Fernald Preserve is a former nuclear production facility located in a rural, residential area 18 miles northwest of Cincinnati, Ohio. The site has gone by many names over the years, including Feed Materials Production Center, Fernald Environmental Management Project, and Fernald Closure Project, but is most often referred to as Fernald.

Production stopped in July 1989 to focus resources on environmental restoration. Ohio EPA and U.S. EPA oversaw cleanup activities at the site. All remediation, with the exception of on-going ground water pumping was completed in 2006.

Restoration returned natural plant and animal communities to the site. The Fernald Preserve is now a green space park with wetlands, ponds, prairies and upland forest areas created based upon original land surveys and post excavation topographies.

Uranium metal products for the nation's defense programs were produced at Fernald, including slightly enriched and depleted uranium. Smaller amounts of thorium metal also were produced.  Uranium, radium and other radioactive materials contaminated the soil, debris, ground water and surface water.

An on-site disposal facility remains at the site containing approximately 3 million cubic yards of contaminated soil and debris. On-going aquifer remediation includes pumping uranium contaminated ground water and associated treatment to meet discharge criteria. Ohio EPA continues an active role in ensuring the cleanup remains protective through monitoring and inspection as well as community outreach.


Ground Water: The Fernald site is located over the Great Miami Aquifer, which is designated a sole source aquifer and considered a valued natural resource. The Southwest Ohio Water Company operates a production wellfield approximately one mile east of Fernald's former production area.

Waste Pits: The six waste pits used during past operations contained approximately 475,000 tons of waste, including uranium, thorium and other radioactive and chemical contaminants. The pits ranged in size from a football field to a baseball diamond, with varying depth from 13 to 30 feet. Two of the pits had a water cover, one had a synthetic cap and the others had a soil cover. The waste pits were in close proximity to, and sometimes in contact with, the Great Miami Aquifer and contributed to contamination of the ground water.

Past Releases: According to an independent dose reconstruction study*, an estimated 340 tons of uranium were released during production at Fernald. The study also estimates 170,000 curies of radon were released from the K-65 silos. A different study released in 1998 estimated the number of lung cancer deaths occurring between 1951 and 2088 may be increased by 1% to 12% from Fernald related radiation exposures. The study focused on lung cancer because exposure to radon contributed 70% to 90% of the lung dose to the Fernald community.

Ground water is contaminated with above background concentrations of uranium approximately one mile south of the site in what is referred to as the south plume. DOE provided bottled water for residents in the south plume area until 1996 when a public drinking water system became operational.

Silos: Four concrete silos were constructed at Fernald to store radioactive materials. Two of them, referred to as the K-65 silos, contained high radium-bearing residues, one contained lower-level dried uranium residues, and one was never used. To reinforce the K-65 silos, a soil berm was added in the 1960s and enlarged in the early 1980s. In 1991, bentonite clay was injected into the tops of the two K-65 silos to cap the high radium residues and reduce radon emissions from the silos. 

* These estimates are reconstructions of past releases and are based on incomplete data. This review of historic data was conducted by Radiological Assessments Corporation (The Fernald Dosimetry Reconstruction Project, August 1996).

In 1997 the site work was reorganized around projects that incorporated operable units (OU) derived through the CERCLA process. The following explain the projects:

Waste Pits Remedial Action Project (includes OU1— Waste storage area, including six waste pits, clearwell and burn pit) The waste pit contents were excavated, thermally dried and shipped by rail to Energy Solutions (formerly Envirocare) disposal facility in Utah.

On-Site Disposal Facility (includes OU2, OU3, and OU5) Contaminated soil and debris was excavated and disposed in the on-site engineered disposal cell. Any waste exceeding the waste acceptance criteria was disposed off-site. No off-site waste was allowed in the disposal cell. The first of eight cells opened for waste placement in 1997. The final cap of cell 8 was installed in 2006.

Facilities Closure and Demolition Project (includes OU3 — Former production area, including all buildings, equipment, inventoried hazardous material and scrap metal piles, and remediation faciities) All on-site buildings were decontaminated and dismantled. Debris within the waste acceptance criteria went in the on-site disposal facility, with higher level materials going off-site. 

Silos Project (includes OU4 — Silos 1-4, including the K-65 silos, their contents and associated piping and soils) Silo 1 & 2 waste was removed by slurry, solidified and placed in casks.  The casks were shipped to a facility in Texas for disposal.  Waste from Silo 3 was removed via vacuum, conditioned for shipment, packaged in bags and sea-land containers and shipped to a disposal facility in Utah.

Soils Characterization and Excavation Project (included OU2 and OU5) Contaminated soils were excavated and those meeting the waste acceptance criteria (WAC) disposed in the on-site disposal facility. Soil and debris exceeding the WAC were shipped off-site for disposal in Utah.  A thorough certification process using real-time radiation detection equipment and standard physical sampling along with rigorous statistical analyses was used to determine cleanup had been completed.

Aquifer Restoration and Waste Water Project (included OU5) The Great Miami Aquifer will be remediated by a combination of treatment, extraction and injection of the ground water. An Advanced Waste Water Treatment Facility was completed in 1994 with additional capacity added in 1998. The South Plume extraction system removal action began pumping in August 1993. The South Field extraction system became operational in 1998. 

Numerous federal and state laws guided environmental remediation at Fernald. The primary driver in Fernald’s cleanup is CERCLA.  Also known as Superfund, CERCLA mandates the study and implementation of cleanup initiatives. Other important regulations that affect the cleanup process include the Resource Conservation and Recovery Act (RCRA—for hazardous waste), the National Pollutant Discharge Elimination System (NPDES—for wastewater discharges), the National Environmental Policy Act (NEPA), and numerous other state and federal laws that protect air, water and land resources.

Ohio EPA worked with DOE to improve efficiency in the regulations that affect Fernald. For example, Ohio EPA worked with DOE to integrate RCRA and CERCLA ground water monitoring programs. Additional streamlining occurred with the integration of RCRA closures and CERCLA cleanups.

Ohio EPA works closely with U.S. EPA under judicial consent decrees and enforceable inter-agency agreements to oversee the cleanup effort at Fernald. The 1991 Consent Agreement was signed by DOE and U.S. EPA which sets schedules for CERCLA documentation and implementation, and clarifies methods for assessing risk. Using state and federal legislation along with negotiated agreements, both EPAs were able to ensure an effective cleanup at Fernald.

In 1994, Ohio EPA created the Office of Federal Facilities Oversight to coordinate and manage regulatory activities at several federal facilities. OFFO was created to provide a consistent and comprehensive approach to oversight. As Fernald closure concluded at the end of 2006, many OFFO staff transitioned to other jobs, while some remained with Ohio EPA's Federal Facilities Section to monitor DOE's Legacy Management activities at Fernald. Ohio EPA’s activities at Fernald are funded through a DOE Cost Recovery Grant.

From 1995 To 2003 Ohio EPA produced annual reports to the public detailing oversight activities. Electronic copies of these can be obtained HERE.

Environmental monitoring was conducted on a regular basis to meet certain objectives at Fernald. The overall objective of sampling at Fernald is to ensure the protection of human and environmental health. Since June 1994, Ohio EPA has taken independent and split samples with the Fernald monitoring team. Ohio EPA has sampled ground water, surface water, sediment, soil, produce and air.

The State of Ohio was tasked to evaluate the adequacy of Fernald’s sampling program. In March 1995, Ohio EPA and the Ohio Department of Health completed the Initial Review of the Fernald Environmental Monitoring Program. In May 1998, OFFO completed the Field Sampling Plan and Standard Operating Procedures, a guidance document for sampling and reporting data at Fernald. In 1996, OFFO participated in the development of Fernald’s new program to integrate and streamline all aspects of environmental monitoring. Fernald’s Integrated Environmental Monitoring Program (IEMP) combined DOE’s project specific monitoring with compliance monitoring and ground water remedy performance monitoring. Fernald’s IEMP monitored for environmental releases and doses to the public as part of DOE Orders. It is governed by CERCLA, RCRA, FFCA, NPDES, ARARs, NESHAPs, and Ohio Fugitive Dust Regulations.

Public availability and working partnerships with all stakeholders helped Ohio EPA’s Fernald team to enhance their cleanup oversight at Fernald. The team encouraged early and active public participation in Fernald cleanup decisions. Through technical availability sessions, environmental monitoring fact sheets, web site, and frequent contact with the public, Ohio EPA’s Fernald team helped to enhance the remediation at Fernald.

In response to elevated concentrations of uranium in the ground water around Fernald, a public water supply system was installed in the area. DOE contributed approximately $5.4 million to this project. Residents living within a certain area were eligible to have the initial installation of the water service paid by DOE. The public water supply system became operational in 1996.

There is a very vocal and active community involved with the cleanup of Fernald. From local residents to elected officials, the public played an active role in Fernald’s remediation. In 1984, after a resident learned she had been drinking contaminated well water, she joined with several area residents to express outrage at the environmental threats to their community. From 1984 - 2006 FRESH, Inc. (Fernald Residents for Environmental Safety and Health) played an active role in the cleanup process at Fernald by influencing key decision-makers, educating the larger community, and participating in the national debate on nuclear waste issues.

The Fernald Citizens Advisory Board, formerly the Fernald Citizens Task Force, a DOE Site Specific Advisory Board, first convened in the summer of 1993 with various representatives from the community. The Advisory Board issued reports and recommendations on future use, waste disposal, cleanup levels, and priorities. They have also influenced major budget and policy initiatives like the 10 Year Plan.

Other groups that have contributed to the Fernald community include the Fernald Citizens for Health and Environment Committee (FCHEC), Fernald Community Reuse Organization (FCRO) and Fernald Living History Project (FLHP).

During site closure in 2006 many of these groups disbanded as their missions were complete. With long-term stewardship issues on the horizon, the Fernald Community Alliance (FCA) emerged as a single voice for the Fernald community.

Fernald Dose Reconstruction Study
by Vicky Dastillung, Vice President F.R.E.S.H., Inc. (Fernald Residents for Environmental Safety and Health)
Posted 10/4/96

Since 1990, the Centers for Disease Control and Prevention (CDC) has overseen a dose reconstruction study being done by Radiological Assessments Corporation. The Study went back and estimated the releases from the Fernald facility during its 38 years of operation - from 1951-1988. Then the study estimated what kind and size of dose the public (within 6.2 miles) may have been exposed to as a result of those releases.

The study results are expressed within ranges, with a high, low and median number. Between 300 and 400 tons of uranium were released to the environment with a median estimate of 340 tons (680,000 lbs.). However, it turns out that radon was the main contributor to the public's risk. This gas came primarily from the K-65 silos located along the western edge of the site. These releases were highest in the 1960s and 1970s. After 1979 the radon releases decreased significantly due to sealing up openings in the domes of the silos. Also of note is the fact that the radon emissions were further reduced in 1991 when the site installed a bentonite clay layer inside the silos. The total radon releases from 1952-1988 ranged from 110,000 curies to 230,00 curies with a median estimate of 170,000 curies. The study took into consideration all the ways that the public could be exposed to radiation, including the air, soil, water, vegetation, milk and food.

So what's the bottom line for the residents?
Your exposure depended on what years you lived in the area, how far away you lived and worked from Fernald, and what you ate and drank. The study could not tell an individual's exposure because everyone varies, but the study did calculate doses for nine hypothetical people that had varying exposures. By comparing your personal details to the one that comes closest to you, you can get a general idea of your exposure. You could also dig into the report to better understand what factors might pertain more to your personal situation. For instance, a person living 6 miles from the site had a median exposure about 1/10 that of someone living a mile from the site. In the case of the hypothetical person living on a farm for 38 years and receiving the highest doses, you could expect an increase of fatal cancer (mostly lung cancer) of beween 1 and 9% with a median of 3%. This means 3 out of 100 people who would theoretically receive the maximum dose that could cause a cancer death resulting from the emissions. That would be above and beyond the 20 or so out of the 100 that would get cancer due to other causes.

This study did not cover the workers at the plant who were exposed to much higher doses during the hours they were at work.

What can you do?
Well, you can't change your past exposures, but you can improve on your current and future exposures. If you smoke, try to stop. Because radon is also a natural substance that enters your home from the ground, you should consider testing your home to see what radon levels exist in your home. There are ways to reduce the levels in your home if your home should test high for this naturally-occurring radon and thus you would be reducing your future exposures. It should be noted that there have been homes in the area that have needed to take such measures. Also, discuss with your doctor whether you may be at increased risk for lung cancer so that your care will reflect that. Be aware of the signs of lung cancer - persistent cough, sputum streaked with blood, chest pain, and recurring pneumonia or bronchitis. While current doses from the Fernald site are much lower than during the production years and before improvements were make to the K-65 silos, you can check on the doses in the Site Environmental Monitoring Reports.

For more information about the Fernald Dosimetry Reconstruction Project, including fact sheets, summary booklets, and copies of the full reports, you can contact the Centers for Disease Control and Prevention, Radiation Studies Branch, Atlanta, GA (Phone: 1-800-232-4636).

Ohio EPA, U.S. EPA, and the Department of Energy (DOE) contractors conduct quarterly inspections of the Fernald Preserve and the on-site disposal facility. More detail about these inspections can be found in the Comprehensive Legacy Management and Institutional Control Plan (LMICP). Reports on each of the post-closure quarterly inspections can be found at DOE's Fernald Preserve inspection page.

 

 

 

 

 

 

Community involvement at Fernald was an important aspect of the cleanup project and remains a key element of long-term stewardship at the Fernald Preserve. Fernald was recognized nationally for successes in public participation programs. The Fernald Preserve continues to educate visitors through indoor and outdoor learning opportunities. Information provided below is relevant to past and current public participation activities at Fernald.

School Outreach

From preschool through college, home school to the classroom, and everything in-between, Ohio EPA's Federal Facility Section has conducted numerous outreach events. From 1998 through 2004 Ohio EPA's Office of Federal Facilities Oversight conducted an annual outreach program with elementary and middle schools. Each spring OFFO staff planted native wildflower seeds with the students. The students were taught about the importance of native plant restoration at Fernald and the value of wetlands to the restoration effort. The students tended to the seedlings all spring. In May, the students were brought on a tour of Fernald and then planted their seedlings in a restoration area at the site.

In 2006, Ohio EPA began partnering with Harrison High School’s Senior Ecology & Literature class to conduct annual monitoring of three mitigation wetlands on the northern portion of Fernald. Prior to field monitoring, the students are taught about Fernald history, macroinvertabrates, and monitoring protocol. The Ohio Vernal Pool Partnership monitoring protocol is used to evaluate the wetlands and data are submitted to OVPP for inclusion in their database. In addition to monitoring data collection, the students write journals discussing their experiences and impressions of the Fernald wetlands.

Ohio EPA has assisted with numerous other school outreach programs at Fernald, including Miami University, Ross Middle School, Seton High School and many others. For more information on setting up a school or scout group at the Fernald Preserve, please contact Sue Walpole or Laura Hafer.

Aquifer Restoration and Waste Water Project (formerly OU5)
The Great Miami Aquifer will be remediated by a combination of treatment, extraction and injection of the ground water. The Advanced Waste Water Treatment Facility was completed in 1994 with additional capacity added in 1998. The South Field extraction system became operational in 1998. The Converted Waste Water Treatment Plant will carry the pump and treat operation to completion.

Facilities Closure and Demolition Project (formerly OU3 - Former production area, including all buildings, equipment, inventoried hazardous material and scrap metal piles)
All on-site buildings were decontaminated and dismantled. Debris within the waste acceptance criteria went in the on-site disposal facility, with higher level materials going off-site.

On-Site Disposal Facility (OSDF, formerly OU2, OU3, and OU5)
Contaminated soil and debris was excavated and disposed in the on-site engineered disposal cell. Any waste exceeding the waste acceptance criteria was disposed off-site. No off-site waste was allowed in the disposal cell.

Silos Project (formerly OU4 - Silos 1-4, including the K-65 silos, their contents and associated piping and soils)
Silo waste was removed, transported by truck, and disposed at off-site disposal facilities.

Soils Characterization and Excavation Project (formerly OU2 and OU5)
Contaminated soils were excavated and those meeting the waste acceptance criteria disposed in the on-site disposal facility.

Waste Pits Project (formerly OU1 - Waste storage area, including six waste pits, clearwell and burn pit)
The waste pit contents were excavated, thermally dried and shipped by rail to Envirocare of Utah.

Northern Pines Plantation

The monoculture of northern pines was enhanced by eliminating some pines and adding native deciduous trees and shrubs. This restoration was designed to enhance the diversity of vegetation and create new wetland and vernal pool areas. A remnant of Lady Bird Johnson's nationwide beautification campaign begun in 1965, the monoculture remained on the northern border of Fernald. In 2002 the stand was thinned to allow for future restoration and diversity efforts. Seven vernal pools and ponds were added to the area to attract aquatic habitat, like this one from November 2002.

Warm Season Grass Seeding Specification

A seeding specification (Specification 2900 - Seeding) was developed for soil stabilization following construction activities at Fernald. The specification focuses on the use of native warm-season (prairie) grasses for all areas that remained undisturbed for more than two years with interim seeding in other areas. The specification was revised based upon field experience, data from the restoration research projects and other sources. 

Area 8 Phase 2 Restoration Project

In the northwestern corner of the site, the Area 8 Phase 2 restoration project includes the construction of an access road, material handling area, ponds, filter wetland and vernal pool. Riparian forest, mixed mesophytic forest, and savanna/grassland habitat supports both the federally endangered Indiana Bat and the state threatened Sloan's Crayfish. In this photo, Ohio EPA staff introduces donor soils and pond muck to a newly constructed wetland in May 2000 to expedite site vegetation and macroinvertebrate colonization. Fishing string and flags tied across the wetland help to prevent impact from geese.

An aesthetic barrier was installed along Willey Road, on the southeastern property boundary. The row of trees was planted in the fall of 1998 per a Fernald Citizens Advisory Board recommendation. The barrier was designed to obstruct the visual impact from construction activities in the clay borrow area (Area 1 Phase 2). The barrier includes conifers and deciduous trees.

Wetland Mitigation Areas

The first mitigation wetland was constructed on the northeast corner of the site in 1999. Lessons learned from developing this wetland were used in implementing wetland construction during site restoration. A research project was conducted by Ohio EPA and the University of Dayton in the Area 1 Phase 1 (A1P1) wetland. A second mitigation wetland (Area 6 Phase 1 or A6P1 or northern mitigated wetland) is located in the northwest corner of Fernald. Approximately eight acres of wetlands and diverse habitat was developed as part of DOE's mitigation requirements for destruction of on-site wetlands. The three basin system is fed by drainage flow from the 26 acre wetland to the north. The system drains into a ditch to the south of the last basin and into Paddy's Run. This photo from December 2003 shows construction of the three basin system looking west. In 2006, Ohio EPA began partnering with Harrison High School to conduct annual monitoring of these wetlands.


Stream Bank Stabilization Projects

Several stream bank stabilization projects were completed at Fernald along the Paddys Run corridor. These projects were aimed at reducing erosion, that in a number of cases was threatening to release additional contamination into the environment. The projects represent a range of approaches from the use of large volumes of rip rap to bioengineering. This photo from February 1998 shows the 30 foot erosion drop at Paddys Run prior to the installation of bendway weirs. The side-by side logs were installed along the toe of the slope and secured along the length of the log with rebar.

Prairie Management

Controlled burns are the preferred method of restoration maintenance at Fernald. The process kills trees and invasive species and enhances the health of a prairie. Burning small areas at a time allows wildlife to escape without harm.

Public Access Habitat Area

The public access habitat area or Ecological Restoration Park developed as a result of a dispute resolution between USEPA and DOE. The project developed a publicly accessible area that represents a number of habitats that were eventually used at the site during restoration. Other parts of Area 8 Phase I were used to conduct restoration research projects by the University of Dayton and the University of Miami. In this photo, Ohio EPA plants native wildflowers and grasses with Ross Middle School in April 1999. The park opened to the public in January 1999.




A number of research projects were initiated at Fernald to develop more effective restoration tools and methods. Click here for a complete list of research publication citations.

Native Grass Revegetation in Disturbed Areas

The project was being conducted by professor Don Geiger, University of Dayton (UD). Methods for establishing native warm season grasses in areas previously disturbed by remediation/excavation were evaluated. The project evaluated various soil amendments (cow manure, compost, wood chips, topsoil), cover crop, and cover material (straw) effects on revegetation. The project was initiated in May 1998.

Impact of Innoculum Soils on Wetland Mitigation

The project was conducted by the University of Dayton and Ohio EPA. The project evaluated the impact of innoculum soils on subsurface microbial and above-grade vegetative communities within restoration projects involving disturbed or degraded soils. Many restoration projects at Fernald occurred in areas where contaminated topsoil was removed leaving a subsoil to be revegetated. Ohio EPA and UD looked at the impact of using donor soils in these areas to stimulate vegetative and microbial community responses. Ohio EPA staff gave a presentation on this topic at the October 2001 international conference for the Society for Ecological Restoration.

Reforestation Method

The project was conducted by professor Carolyn Keiffer, Miami University Middletown campus. This research investigated the most effective density of seedlings and saplings required for successful restoration of forest habitats at Fernald. The project was initiated in June, 1998 with evaluation of reference sites. Planting began in March, 1999 in an area located in Area 8 Phase 1, east of the Public Access Habitat Area.

American Chestnut Reintroduction

The project was conducted by professor Carolyn Keiffer, Miami University Middletown campus and focused on establishing a population of blight resistant American Chestnut trees in southwest Ohio. The project used 7/8 pure chestnuts received as seeds from the American Chestnut Foundation. The project was initiated February 1998. Seedlings were planted in Spring 1999. The chestnut planting area is located in Area 8 Phase 1, north of the Public Access Habitat Area.

Amphibian Monitoring

Butterfly Monitoring

Ohio EPA conducted butterfly monitoring upon the completion of the A1PI mitigated wetland at the end of 1999. For more than two years Ohio EPA made observations along a transect

Paddys Run Conservation Project

Our future flows through our landPaddys Run at the Fernald Preserve

By purchasing conservation easements in the Paddys Run watershed, near Fernald,  we will protect water quality in streams and ground water.  In addition to the $14 million DOE has already spent restoring the Fernald site, the natural resource damages settlement requires payment of $13,750,000 to Ohio by the United States for various habitat enhancements and land protection on or near Fernald in order to protect and improve water quality in Paddys Run and the Great Miami Aquifer. The Fernald trustees, including Ohio EPA, the Department of Energy and US Fish and Wildlife Service, are partnering with Three Valley Conservation Trust to enhance habitat and protect water quality near the Fernald Preserve. 

A conservation easement is a customized legal agreement that permanently limits certain uses of the land, or a portion of the land, in order to protect its natural and/or agricultural values. The landowner retains all other rights and may sell or transfer the land to heirs, but all future owners are bound by the easement's terms. A conservation easement will protect land against future real estate development or industrial use, while allowing the landowner to continue current uses. 

 Other Resources

CERCLA defines a natural resource as land, fish, wildlife, biota, air, water, ground water, drinking water supplies and other such resources belonging to, managed by, held in trust by, or appertaining to, the trustees. Natural resources were injured during the production years at Fernald.

Ohio included a $206 million claim for natural resource injury in its 1986 lawsuit against DOE. In 1988, Ohio and DOE agreed to put this claim on hold until the signing of the site's record of decision. In 1993, DOE initiated discussions with the trustees to determine the feasibility of integrating the trustees' concerns with future remedial design activities. The trustees identified their desire to fulfill their obligations by integrating their concerns with remedial design and restoration activities. In 1998 DOE initiated restoration activities at the site based on the Draft Natural Resource Restoration Plan.

In 2008 the State of Ohio and United States Department of Energy (DOE) settled for natural resource damages at Fernald.
