Grain Bin Clearance

Grain Bin Clearance

When you start to plan for a new grain bin, please contact Osceola Electric Cooperative. Your cooperative 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.

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)C2-2007 "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. (As adopted by the Iowa Utilities Board)

The 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 graph below shows a drawing of the specific clearances required. If you have any questions concerning the drawings or clearance regulations, please contact Osceola Electric Cooperative at (712) 754-2519 / 1-888-754-2519 and L & O Power Cooperative at (712) 472-2556.
