§ 130d.44. Limitations on land application of soil and groundwater contaminated with agricultural chemicals.
When applying soil and groundwater contaminated with agricultural chemicals the approved applicant shall assure the following:
(1) Labeling rates. Pesticide contaminated soil and groundwater shall be applied to a site or crop, or both, in a manner consistent with labeling directions and requirements for that pesticide.
(2) Annual crops. In the case of annual crops, the crop shall be grown on the application area during the season that the application is made.
(3) Postharvest application. If land application is conducted in the fall or postharvest, the crop following the application shall be suitable for the labeling requirements of the agricultural chemicals contained in the soil and groundwater to be land applied.
(4) Site suitability. Site suitability will be based on the land application proposal. The information contained within the land application proposal shall evidence that the rates of application of the soil and groundwater contaminated with agricultural chemicals will comply with labeling requirements, will not exceed labeling rates, will not exceed additivity requirements and will not cause damage to the proposed application site or adjacent land or water. General slope, drainage characteristics, presence of shallow groundwater, distance to surface waters and suitability for agricultural purposes are some of the characteristics that will be considered.
(5) Application of soil piles. To allow for proper incorporation of contaminated soil piles, the soil piles may not be applied overtop of the soil at the application site at a thickness greater than 1/2 inch. The soil piles shall be incorporated into the soil at the application site to a depth of at least 6 inches, unless otherwise authorized by the Department.
(6) Application techniques. Soil and groundwater contaminated with agricultural chemicals may not be applied by any type of spray irrigation equipment or by aerial equipment or any other technique that may cause or lead to excessive drift of the agricultural chemicals contained in the soil or groundwater unless the person has demonstrated in the land application proposal the equipment or technique will not cause aerosol transport offsite or onto a field that will contain an incompatible crop, and the Department has approved in writing this machinery or technique.
(7) Ponding and standing accumulations. Soil and groundwater contaminated with agricultural chemicals shall be applied to the soil surface and incorporated in a manner that prevents ponding or standing accumulations of contaminated soil or groundwater, or both, on or overtop of the topsoil at the application site.
(8) Pasturing or grazing. Livestock may not be pastured or allowed to graze on areas where soil and groundwater contaminated with agricultural chemicals has been applied for at least 3 years subsequent to the application, unless otherwise approved by the Department in writing.
(9) Land use and crops. The use that will be made of the proposed application area and the crops that will be grown on the site subsequent to the application of the soil and groundwater contaminated with agricultural chemicals shall be consistent with the labeling requirements of the pesticides contained in the soil piles or groundwater to be applied.
