## Abstract

This final rule amends the U.S. Department of Agriculture's (USDA's) National List of Allowed and Prohibited Substances (National List) to enact five recommendations submitted to the Secretary of Agriculture (Secretary) by the National Organic Standards Board (NOSB) on November 5, 2009, and December 2, 2011. This final rule amends the exemptions (uses) for one substance, peracetic acid, for organic crop production. This final rule also amends the exemptions for three substances used in organic handling: potassium hydroxide, silicon dioxide, and beta-carotene extract color. This final rule also removes the allowance for nonorganic annatto extract color from the National List for organic handling.
