Back in December 2017, I wrote about a change in the Anhydrous Ammonia fertilizer industry that would most likely require the industry to perform an MOC and PSSR. (A new grade of anhydrous ammonia fertilizer means a MOC, PSSR, etc.) Now that the product has received its official approval and has found its way into the
