In this document, the Alcohol and Tobacco Tax and Trade Bureau adopts as a final rule, with some changes, a proposed revision of its distilled spirits plant regulations. The revision modernizes the requirements for operating distilled spirits plants and includes a number of organizational changes to improve the layout of the regulatory texts. These changes make the regulations easier to apply, thereby facilitating compliance by distilled spirits plant proprietors and allowing those proprietors to operate in a more efficient manner. The revision also incorporates plain language principles in order to improve the clarity and readability of the regulatory texts.
