27 C.F.R. § 19.206 Curtailment and extension of plant premises for the manufacture of eligible flavors.
Title 27 - Alcohol, Tobacco Products and Firearms
(a) General. The premises of a distilled spirits plant may be alternately curtailed and extended, as provided in this section, to permit the use of the facilities for the manufacture of eligible flavors. (b) Qualifying documents. When a portion of the distilled spirits plant premises is first to be curtailed or extended as provided in this section, the proprietor shall file with the appropriate TTB officer— (1) An application for registration, Form 5110.41, to cover alternate extension and curtailment of the premises, and (2) A special diagram, in duplicate, delineating the premises as they will exist, both during extension and curtailment, and clearly depicting all buildings, floors, rooms, areas, equipment and spirits lines (identified individually by letter or number) which are to be subject to alternation, in their relative operating sequence. (c) Proprietor's responsibility. Once such qualifying documents have been approved by the appropriate TTB officer, the designated premises and equipment may be alternately curtailed or extended pursuant to notice on Form 5110.34. Portions of the premises to be excluded by curtailment or included by extension shall not be used for purposes other than as set forth in the current notice. The proprietor shall remove all spirits, denatured spirits, articles, and wines from the premises or equipment which are to be curtailed from bonded premises or are to be included by extension of bonded premises prior to the effective date and hour of the notice, except that— (1) Bonded spirits on portions of bonded premises that are to be curtailed need not be removed if the spirits are taxpaid concurrent with the filing of Form 5110.34 to effect curtailment; and (2) Taxpaid spirits which are on portions of premises to be included by extension of bonded premises and which have not been used in the manufacture of a nonbeverage product need not be removed if the spirits are to be dumped immediately and returned to bond under the provisions of subpart U of this part. (d) Separation of premises. The portion of the premises which is to be curtailed or extended as provided in this section shall be separated from the remaining portion of the distilled spirits plant in a manner which satisfies the appropriate TTB officer that the revenue will not be jeopardized. (Sec. 201, Pub. L. 85–859, 72 Stat. 1349, as amended, 1353, as amended (26 U.S.C. 5172, 5178)) [T.D. ATF–297, 55 FR 18063, Apr. 30, 1990]
