During the last several years, more than two dozen deaths and serious injuries have occurred on Iowa farms, when grain augers have come in contact with overhead power lines.  If you are planning to locate a new grain bin (or move an existing one) at your farm, please contact Southern Iowa Electric Cooperative immediately.  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 SIEC at 800-607-2027 for help.  

SIEC will provide assistance in planning for a safe environment for everyone working and living around grain bins. The State of Iowa requires specific clearances for electric lines around grain bins, with different standards for those filled by portable and permanent augers, conveyors and elevators.

Below there is a drawing of the specific clearances required for both scenarios. If you have any questions concerning the drawings, please contact SIEC.

According to the Iowa Electric Safety Code found in Iowa Administrative Code Chapter 199 – 25.2(3) b: An electric utility may refuse to provide electric service to any grain bin built near an existing electric line which does not provide the clearances required by the American National Standards Institute (ANSI) C2-2017 “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 Sept. 9, 1992, or to grain bins loaded by permanently installed augers, conveyors, or elevator systems installed after Dec. 24, 1997. The Iowa Utilities Board has adopted this language.

SIEC 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. If you have any questions concerning clearance regulations, please call SIEC at 800-607-2027.
