United Nuclear Corp. V. Allendale Mutual Insurance Co‪.‬

Plaintiff United Nuclear Corporation (UNC) brought suit under two different policies of insurance against defendants Allendale Mutual Insurance Company (Allendale) and its subsidiary, Appalachian Insurance Company (Appalachian). Each insurer provided different coverage to UNC. UNC sought reimbursement for business interruption and property damage losses that occurred when a tailings embankment failed at UNC's Churchrock uranium mill site. Both Allendale and Appalachian denied coverage. The trial court, finding coverage under Allendale's policy, awarded judgment to UNC for losses and damages, including attorney's fees, prejudgment interest and punitive damages. The trial court found in favor of Appalachian. Allendale appeals. We affirm in part and reverse in part.
