RONALD LEE GILMAN, Circuit Judge. James Clemons died from chronic obstructive pulmonary disease (COPD) in 2015. His widow, Peggy Clemons, filed a claim for survivor’s benefits under the Black Lung Benefits Act, 30 U.S.C. § 901 et seq., contending that her deceased husband’s respiratory illness was caused by his coal-mining employment at Huscoal, Inc. The Administrative Law Judge (ALJ) granted Clemons’s claim, and the Benefits Review Board (the Board) affirmed, concluding that the evidence was sufficient to establish the presence of legal pneumoconiosis. Huscoal and its insurance carrier, Security Insurance Company of Hartford, petition this court for review of that decision, arguing that the ALJ improperly relied on a doctor’s opinion that was based on inaccurate information. For the reasons set forth below, we DENY the petition for review.
