Cooperative Grain and Supply is adding another 288,000 bushels of storage capacity to its Marion location. That will bring Marion’s capacity above 1 million bushels.

The pilings, footings, and floor for the new bin have been completed, general manager Lyman Adams wrote in a newsletter. The project should be completed and ready to use by Sept. 15.

There are also plans to add another 300,000-bushel tank at the Hillsboro location, but there hasn’t been a final decision yet, Adams wrote.
