Hazardous Waste: Agencies Should Take Steps to Improve Information on USDA's and Interior's Potentially Contaminated Sites
Highlights
What GAO Found
The U.S. Department of Agriculture (USDA) and the Department of the Interior (Interior) have identified many contaminated and potentially contaminated sites, but neither agency has a complete inventory. As of April 2014, USDA had identified 1,491 contaminated sites and many potentially contaminated sites, including landfills and shooting ranges. However, USDA does not have a reliable, centralized site inventory or plans and procedures for completing one, in particular, for abandoned mines. Without a reliable inventory or plans and procedures for developing one, USDA cannot effectively manage its cleanup programs. As of April 2014, Interior had an inventory of 4,722 sites with confirmed or likely contamination. In addition, Interior's Bureau of Land Management (BLM) had identified over 30,000 abandoned mines that were not yet assessed for contamination, and this inventory is not complete. BLM is working to improve the completeness and accuracy of its inventory. In fiscal year 2013, USDA allocated over $22 million for environmental cleanup efforts, and Interior allocated over $13 million. Specifically, in fiscal year 2013, USDA allocated about (1) $3.7 million for cleanup projects department-wide, primarily for one large site; (2) $4.3 million to mitigate contamination at grain silos and foreclosure properties; and (3) approximately $14 million for the U.S. Forest Service to assess and clean up sites. In fiscal year 2013, Interior allocated almost $10 million for cleanup projects department-wide, the National Park Service allocated an additional $2.7 million and the Fish and Wildlife Service allocated over $800,000 for environmental assessment and cleanup projects. In addition, BLM allocated more than $34 million to its hazardous waste management and abandoned mine programs. Both USDA and Interior report probable and reasonably estimable environmental liabilities on their financial statements. In fiscal year 2013, USDA reported environmental liabilities of $176 million, most of which was for asbestos cleanup. Interior reported environmental liabilities of $192 million to address 434 sites. Interior also disclosed that it will incur $62 million to $139 million in cleanup costs at government-acknowledged sites--sites with damage caused by nonfederal entities. The majority of the costs Interior disclosed were for cleanup activities at 85 abandoned mines. As USDA and Interior complete their inventories and assess them for contamination, it might be expected that related environmental costs for both agencies will increase as additional sites are considered. The Environmental Protection Agency's (EPA) role with regard to USDA and Interior sites is to maintain a list of potentially contaminated sites based on data from these agencies, take steps to assure that the agencies assess these sites for contamination, determine whether the sites should be proposed for the National Priorities List, and oversee certain cleanup activities. EPA has compiled a docket list of 260 USDA sites and 528 Interior sites that may pose health or environmental risks, most of which have been assessed. Disagreement with USDA and Interior over their need to assess the remaining sites and differing information on whether this requirement has been met at some sites means EPA cannot assure that the assessments are conducted in a timely manner and, ultimately, that sites most in need of remediation are addressed. GAO recommends that USDA develop plans and procedures for completing its site inventories and that EPA clarify which USDA and Interior sites need an environmental assessment. Interior and EPA generally agreed with GAO's findings. USDA disagreed that its incomplete inventory affects the effectiveness of its cleanup programs, but GAO continues to believe that effective program management requires reliable data.
Why GAO Did This Study
USDA and Interior manage over 600 million acres of land, including sites contaminated from prior uses or events, such as mining or toxic spills. These lands are managed by five Interior agencies, including BLM and the National Park Service, and five USDA agencies, including the U.S. Forest Service. These agencies must identify and report to EPA certain facilities that may threaten human health or the environment and, under some circumstances, clean them up. They must also report cost estimates for addressing contamination at certain sites, called environmental liabilities. GAO was asked to review the status of USDA's and Interior's potentially contaminated sites. This report examines USDA's and Interior's (1) efforts to identify these sites, (2) funding to address the sites, (3) reported environmental liabilities, and (4) EPA's role in addressing the sites. GAO reviewed relevant laws and government accounting standards; examined agencies' policies, site inventory data from September 2013 to July 2014, and financial statements; and interviewed EPA, Interior, and USDA officials
Recommendations
GAO recommends that USDA develop plans and procedures for completing its site inventories and that EPA clarify which USDA and Interior sites need an environmental assessment. Interior and EPA generally agreed with GAO’s findings. USDA disagreed that its incomplete inventory affects the effectiveness of its cleanup programs, but GAO continues to believe that effective program management requires reliable data.
Recommendations for Executive Action
| Agency Affected | Recommendation | Status |
|---|---|---|
| Department of Agriculture | To ensure that USDA has the information needed to better identify potentially contaminated sites--particularly abandoned mines--on properties it manages and, thereby, help minimize possible risks to human health and the environment, the Secretary of Agriculture should direct the heads of the department's land management agencies to develop plans and procedures for completing their inventories of potentially contaminated sites. |
Closed – Implemented
USDA created a new database--the National Environmental Accomplishment Tracking (NEAT) database--that includes information about sites that are potentially contaminated in addition to sites where contamination is confirmed. USDA uses NEAT to manage its inventory of potentially contaminated and contaminated sites, among other things. According to USDA officials, USDA and Forest Service staff identified and eliminated duplicate entries in the new database, where possible. According to USDA officials, within the budget available each year, agency officials conduct field visits at potentially contaminated abandoned mine sites to verify information and confirm whether the site is contaminated. According to agency officials, any newly identified potentially contaminated sites are to be included in NEAT, as it is the database of record. We believe these actions demonstrate that USDA's land management agencies have procedures in place to continually update the inventory of potentially contaminated sites.

| Environmental Protection Agency | To help resolve disagreements between EPA and USDA and Interior regarding which remaining docket sites require preliminary assessments, the Administrator of EPA should direct the Office of Federal Facilities Restoration and Reuse to review available information on USDA and Interior sites where EPA's Superfund Enterprise Management System indicates that a preliminary assessment has not occurred to determine the accuracy of this information, and update the information, as needed. |
Closed – Implemented
In response to this recommendation, officials from EPA's Federal Facilities Restoration and Reuse Office (FFRRO) reviewed information from EPA's Superfund Enterprise Management System on the status of USDA and Interior sites on the docket and generated a list of sites with no record of a preliminary assessment. FFRRO shared this list with USDA and Interior officials in January 2016, held meetings with these officials to determine the accuracy of the list, and updated the status of the sites in EPA's system as needed.

| Environmental Protection Agency | To help resolve disagreements between EPA and USDA and Interior regarding which remaining docket sites require preliminary assessments, the Administrator of EPA should direct the Office of Federal Facilities Restoration and Reuse to work with the relevant USDA and Interior offices to obtain any additional information needed to assist EPA in determining the accuracy of the agency's data on the status of preliminary assessments for these sites. |
Closed – Implemented
According to EPA officials and documents, in response to this recommendation, EPA's Federal Facilities Restoration and Reuse Office (FFRRO) held several meetings with USDA and Interior to discuss, among other issues, whether the requirement to conduct a preliminary assessment at the identified sites had been met or if additional work was needed to meet this requirement. In 2018, according to EPA officials, FFRRO staff held quarterly meetings with Interior to discuss various sites and policy issues. Officials said FFRRO held three additional meetings in 2018 with Interior to specifically discuss the progress of preliminary assessments at docket sites.

| Environmental Protection Agency | To help resolve disagreements between EPA and USDA and Interior regarding which remaining docket sites require preliminary assessments, the Administrator of EPA should direct the Office of Federal Facilities Restoration and Reuse to, after completing this review, inform USDA and Interior whether the requirement to conduct a preliminary assessment at the identified sites has been met or if additional work is needed to meet this requirement |
Closed – Implemented
In January 2016, FFRRO sent letters to USDA and Interior which included information showing the status of each department's sites and requested that the departments work with EPA to determine the accuracy of the data. In addition, for sites where EPA believed a preliminary assessment was needed, EPA asked the departments to provide a schedule for completion of the preliminary assessment. In a June 2016 letter to EPA, USDA responded that with help from EPA regions they were able to substantially reconcile the list, complete preliminary assessments or their equivalent, and provide a status to EPA on its 251 sites. In an October 2016 letter to EPA, Interior responded that 79 sites had one or more areas of uncertainty regarding their status within the Federal Facilities Docket system. According to EPA officials, as of March 2019, EPA and Interior had obtained information on 69 of the 79 sites, and EPA staff were continuing to work with DOI on the other 10 sites.
