Gypsum users and gypsum suppliers are shielded from civil damages if the section’s requirements are met, and the commissioner may adopt rules to implement the section.
§1424. Gypsum; analysis; limitation of liability A. The Legislature of Louisiana hereby finds: (1) That gypsum, one of the earliest forms of fertilizer and soil amendment used in the United States, is a byproduct of many manufacturing facilities in Louisiana. (2) Byproduct gypsum that is not recycled for other uses results in costly on-site storage and disposal in landfills. (3) Gypsum (calcium sulphate) is widely used in agricultural crop production to provide essential plant nutrients and can improve overall plant growth. (4) Gypsum can also improve the physical properties of soils, reducing erosion losses of soil and nutrient concentrations. B. Any agricultural producer or landowner that utilizes gypsum, and any supplier of gypsum to the agricultural producer, shall not be liable for any civil damages arising out of the utilization of the gypsum if all the following requirements are met: (1) The requirements of this Section, and any rules and regulations adopted pursuant to this Section, are complied with. (2) The agricultural producer obtains gypsum, without any cost, from a source where the gypsum is being stored as a byproduct of a manufacturing process. (3)(a) The agricultural producer shall use gypsum only on his land or with written authorization from the landowner once the gypsum is analyzed and passes analytical tolerances established by the department, in consultation with the Louisiana State University Agricultural Center. Such analysis shall be conducted by an accredited laboratory. (b) The tolerances shall be established using as a guide the most recent version of the Conservation Practice Standard, Amending Soil Properties with Gypsum Products, Code 333 as published by the Natural Resources Conservation Service of the United States Department of Agriculture and any regulatory requirements that pertain to the use of soil amendments required by the United States Environmental Protection Agency. C. The commissioner is authorized to promulgate rules and regulations in accordance with the Administrative Procedure Act to implement the provisions of this Section, including the establishment of analytical tolerances for gypsum.
