Grain Bin Clearance Information

In the interest of safety, when you start to plan for a new grain bin, please contact Chariton Valley Electric Cooperative.

Chariton Valley can help 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.

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)C2-2012 “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 elevator systems installed after December 24, 1997. (As adopted by the Iowa Utilities Board)

Chariton Valley is required by the Iowa Utilities Board to provide annual notice to farmers, farm lenders, grain bin merchants, and city and county zoning officials.

The grain bin drawings show the specific clearance required by the code, but If you have any questions concerning clearance regulations – or what needs to be done before you begin placing a new grain bin or moving an existing one please call our office at 641-932-7126 or 800-475-1702.
