By February 1, 1992, all washing of commercial fertilizer application equipment at liquid and nonliquid bulk commercial fertilizer storage facilities must be conducted within an area that complies with § 12:44:05:27. No commercial fertilizer rinsates or wash waters from commercial fertilizer equipment may be disposed of through sanitary or storm sewer systems. Washing of commercial fertilizer equipment in the field is permissible and encouraged if it is performed at the site of the final commercial fertilizer application on a given day and no runoff from the wash site occurs. Any accumulated liquid or material, that contains a 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.
