Item 1.04     Mine Safety - Reporting of Shutdowns and Patterns of Violations.

On April 8, 2014, Hawaiian Cement, an indirect subsidiary of MDU Resources Group, Inc., received an imminent danger order issued by the Mine Safety and Health Administration under section 107(a) of the Federal Mine Safety and Health Act of 1977 at the Puunene Quarry in Maui, Hawaii.  The order was issued upon observation that a miner was guiding concrete blocks into place by hand.  The blocks were estimated to weigh more than one ton and were suspended about four feet above ground level by a single chain.   Miners were working to stack the blocks up to six feet high.  The miners were not using safety devices to guard against falling object hazards.  The miner was removed from the area of the suspended load and it was safely lowered to the ground, thereby terminating the order.
