While baling hay in the D1 reclamation area, a roll of hay caught on fire inside the baler, when it was kicked out, it caused about 7 acres of hay meadow and about 7 to 8 acres of an adjacent pine plantation totaling about 14 to 15 acres to burn. The fire never affected the mining operation and did not leave Luminant property. The fire was contained in about 1 hr and 30 minutes.
