Black Lung Benefits Program: Improved Oversight of Coal Mine Operator Insurance Is Needed

What GAO Found

Coal mine operator bankruptcies have led to the transfer of about $865 million in estimated benefit responsibility to the federal government's Black Lung Disability Trust Fund (Trust Fund), according to DOL estimates. The Trust Fund pays benefits when no responsible operator is identified, or when the liable operator does not pay. GAO previously testified in June 2019 that it had identified three bankrupt, self-insured operators for which benefit responsibility was transferred to the Trust Fund. Since that time, DOL's estimate of the transferred benefit responsibility has grown—from a prior range of $313 million to $325 million to the more recent $865 million estimate provided to GAO in January 2020. According to DOL, this escalation was due, in part, to recent increases in black lung benefit award rates and higher medical treatment costs, and to an underestimate of Patriot Coal's future benefit claims.

DOL's limited oversight of coal mine operator insurance has exposed the Trust Fund to financial risk, though recent changes, if implemented effectively, can help address these risks. In overseeing self-insurance in the past, DOL did not estimate future benefit liability when setting the amount of collateral required to self-insure; regularly review operators to assess whether the required amount of collateral should change; or always take action to protect the Trust Fund by revoking an operator's ability to self-insure as appropriate. In July 2019, DOL began implementing a new self-insurance process that could help address past deficiencies in estimating collateral and regularly reviewing self-insured operators. However, DOL's new process still lacks procedures for its planned annual renewal of self-insured operators and for resolving coal operator appeals should operators dispute DOL collateral requirements. This could hinder DOL from revoking an operator's ability to self-insure should they not comply with DOL requirements. Further, for those operators that do not self-insure, DOL does not monitor them to ensure they maintain adequate and continuous commercial coverage as appropriate. As a result, the Trust Fund may in some instances assume responsibility for paying benefits that otherwise would have been paid by an insurer.

Why GAO Did This Study

In May 2018, GAO reported that the Trust Fund, which pays benefits to certain coal miners, faced financial challenges. The Trust Fund has borrowed from the U.S. Treasury's general fund almost every year since 1979 to make needed expenditures. GAO's June 2019 testimony included preliminary observations that coal operator bankruptcies were further straining Trust Fund finances because, in some cases, benefit responsibility was transferred to the Trust Fund.

This report examines (1) how coal mine operator bankruptcies have affected the Trust Fund, and (2) how DOL managed coal mine operator insurance to limit financial risk to the Trust Fund. GAO identified coal operators that filed for bankruptcy from 2014 through 2016 using Bloomberg data. GAO selected these years, in part, because bankruptcies were more likely to be resolved so that their effects on the Trust Fund could be assessed. GAO analyzed information on commercially-insured and self-insured coal operators, and examined workers' compensation insurance practices in four of the nation's top five coal producing states. GAO also interviewed DOL officials, coal mine operators, and insurance company representatives, among others.
