0581-AE25 202510 The Regulatory Plan and the Unified Agenda of Federal Regulatory and Deregulatory Actions 0581 Agricultural Marketing Service AMS 0500 Department of Agriculture USDA National List of Allowed and Prohibited Substances: Recommendations From the NOSB Fall 2021, Fall 2022 and Fall 2024 Meetings (Crops and Livestock) (AMS-NOP-22-0029)

The National List identifies the synthetic substances that may be used in organic crop and livestock production as well as the nonsynthetic (natural) substances that may not be used. It also identifies the nonorganic substances that may be used in or on processed organic products. This proposed rule would amend the National List section of the organic regulations related to organic crop and livestock production. The rule would provide additional tools to organic producers, allowing carbon dioxide in organic crop production and meloxicam as a pain treatment in organic livestock production. Additionally, the rule would remove overly burdensome restrictions for methionine, an amino acid, in organic poultry feed and would affirm that sodium nitrate may be used as a fertilizer in organic crop production, with certain conditions to protect soil quality. Amendments in this proposed rule are based on recommendations from the National Organic Standards Board (NOSB) from the Fall meetings in 2021, 2022, and 2024.
