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

On September 5, 2013, Knife River Corporation - Northwest, 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 Gold Creek Placer mine in Gold Creek, Montana.  The order was issued upon observation that two miners were not wearing fall protection while working on the elevated head pulley of a feed conveyor. The miners were standing in the feed hopper of the conveyor and were approximately 10 feet above ground level. The miners had been trained in the use of fall protection and harnesses were available to them, however the miners were not wearing harnesses at the time of the citation. The miners were removed from the feed conveyor. No one was injured as a result of the incident and the order was terminated.

This Form 8-K was not filed within 4 business days after receipt of the imminent danger order because company personnel did not follow company procedure, which requires prompt internal reporting. The company has taken measures to correct this reporting lapse and ensure information that is reportable under Item 1.04 of Form 8-K will be reported in a timely manner.
