Grain Bin Clearances

(click to enlarge)

The State of Iowa requires specific clearances for electric lines around grain bins, with different standards for those filled by portable augers, conveyors and elevators and permanent equipment. In fact, the Iowa Electrical Safety Code found in Iowa Administrative Code Chapter 199--25.2(3)b states:

An electric utility may refuse to provide electric service to any grain bin built near an existing electric line which does not provide the clearance required by The American National Standards Institute (ANSI) C2-2002 "National Electrical Safety Code," Rule 234f. This paragraph "b" shall apply only to grain bins loaded by portable augers, conveyors or elevators and built after September 9, 1992, or to grain bins loaded by permanently installed augers, conveyors or elevators built after December 24, 1997.

This language has been adopted by the Iowa Utilities Board.

Your local electric cooperative is required by the Iowa Utilities Board to provide this annual notice to farmers, farm lenders, grain bin merchants and city and county zoning officials. The drawings on this page show the specific clearances required by the code. If you have any questions concerning these clearance regulations--or what needs to be done before you begin placing a new grain bin or moving an existing one--please call your electric c-op for help.
