The Washington County Board of Supervisors met on Tuesday. On the agenda was the approval of Vision Ag of Ainsworth’s construction of a new anhydrous ammonia tank. Brian Wood, Ainsworth location manager, explained why the construction was necessary, “What we are wanting to do is expand our storage supply by adding another tank at the Ainsworth location next to the one that is already there. We are just having too much trouble with getting the supply in the busy season.” The Supervisors approved the construction of the new anhydrous tank. The public notice was published by the Auditor last week.
