Commercial fertilizer loading and mixing areas

12:44:05:27. Commercial fertilizer loading and mixing areas. By February 1, 1992, all loading and mixing of liquid and nonliquid bulk commercial fertilizer, unless performed in the field of application, must be done within a containment area. The containment area must be constructed of concrete of sufficient strength to withstand the load weight of vehicles which will be on the containment area, and the containment area must be large enough to prevent spillage onto unprotected areas. The containment area must be designed to allow the collection of spilled materials. The containment area must be constructed, using curbs or other means, to prevent spilled materials from running out of the containment area. Any accumulated liquid or material, that contains fertilizer, within the containment area must be applied to a field or fields at normal fertilizer rates or used in a liquid mixing operation. This section also applies when a commercial fertilizer is combined with a pesticide. When the accumulated liquid or material contains a pesticide, the accumulated liquid or material must be applied to a field or fields at normal pesticide application rates or used in a liquid mixing operation.
