Title 27 - Alcohol, Tobacco Products and Firearms
The continuity of the distilled spirits plant shall be unbroken except for separations by public waterways, thoroughfares, or carrier rights-of-way. However, where there are other separations of the plant premises and all parts of the plant premises are in the same general location, the appropriate TTB officer may approve the registration of the distilled spirits plant if he finds no jeopardy to the revenue.
