It has been brought to our attention that the Iowa Utilities Board is checking Grain Bin Notification versions during inspections. In September 2017, IAMU updated the Grain Bin Notification brochure. The diagrams have not changed, but the reference has been updated to reference the 2017 Edition of the National Electrical Safety Code (NESC). Please check your Grain Bin Notification brochures and ensure you are using the most updated version. If you need an updated version, you can find that on IAMU's website at http://members.iamu.org/?page=Electric_Calendar toward the bottom of the regulatory calendar. If you have any questions, please feel free to contact Krista Wenzel, IAMU Regulatory Partner, at eefiling@iamu.org or by phone at 402.441.1684.
