27 CFR § 9.12 - AVA petition requirements.
(a) Establishment of an AVA in general. A petition for the establishment of a new AVA must include all of the evidentiary materials and other information specified in this section. The petition must contain sufficient information, data, and evidence such that no independent verification or research is required by TTB.
(1) Name evidence. The name identified for the proposed AVA must be currently and directly associated with an area in which viticulture exists. All of the area within the proposed AVA boundary must be nationally or locally known by the name specified in the petition, although the use of that name may extend beyond the proposed AVA boundary. The name evidence must conform to the following rules:
(ii) Source of name and name evidence. The name and the evidence in support of it must come from sources independent of the petitioner. Appropriate name evidence sources include, but are not limited to, historical and modern government or commercial maps, books, newspapers, magazines, tourist and other promotional materials, local business or school names, and road names. Whenever practicable, the petitioner must include with the petition copies of the name evidence materials, appropriately cross-referenced in the petition narrative. Although anecdotal information by itself is not sufficient, statements taken from local residents with knowledge of the name and its use may also be included to support other name evidence.
(2) Boundary evidence. The petition must explain in detail the basis for defining the boundary of the proposed AVA as set forth in the petition. This explanation must have reference to the name evidence and other distinguishing features information required under this section. In support of the proposed boundary, the petition must outline the commonalities or similarities within that boundary and must explain with specificity how those elements are different in the adjacent areas outside that boundary.
(3) Distinguishing features. The petition must provide, in narrative form, a description of the common or similar features of the proposed AVA affecting viticulture that make it distinctive. The petition must also explain with specificity in what way these features affect viticulture and how they are distinguished viticulturally from features associated with adjacent areas outside the proposed AVA boundary. For purposes of this section, information relating to distinguishing features affecting viticulture includes the following:
(i) Climate. Temperature, precipitation, wind, fog, solar orientation and radiation, and other climate information;
(ii) Geology. Underlying formations, landforms, and such geophysical events as earthquakes, eruptions, and major floods;
(iii) Soils. Soil series or phases of a soil series, denoting parent material, texture, slope, permeability, soil reaction, drainage, and fertility;
(iv) Physical features. Flat, hilly, or mountainous topography, geographical formations, bodies of water, watersheds, irrigation resources, and other physical features; and
(v) Elevation. Minimum and maximum elevations.
(4) Maps and boundary description. -
(i) Maps. The petitioner must submit with the petition, in an appropriate scale, the U.S.G.S. map(s) showing the location of the proposed AVA. The exact boundary of the AVA must be prominently and clearly drawn on the maps without obscuring the underlying features that define the boundary line. U.S.G.S. maps may be obtained from the U.S. Geological Survey, Branch of Distribution. If the map name is not known, the petitioner may request a map index by State.
(ii) Boundary description. The petition must include a detailed narrative description of the proposed AVA boundary based on U.S.G.S. map markings. This description must have a specific beginning point, must proceed unbroken from that point in a clockwise direction, and must return to that beginning point to complete the boundary description. The boundary description must refer to easily discernable reference points on the U.S.G.S. maps. The proposed AVA boundary description may rely on any of the following map features:
(A) State, county, township, forest, and other political entity lines;
(B) Highways, roads (including unimproved roads), and trails;
(C) Contour or elevation lines;
(D) Natural geographical features, including rivers, streams, creeks, ridges, and marked elevation points (such as summits or benchmarks);
(E) Human-made features (such as bridges, buildings, windmills, or water tanks); and
(F) Straight lines between marked intersections, human-made features, or other map points.
(b) AVAs within AVAs. If the petition proposes the establishment of a new AVA entirely within, or overlapping, an existing AVA, the evidence submitted under paragraph (a) of this section must include information that both identifies the attributes of the proposed AVA that are consistent with the existing AVA and explains how the proposed AVA is sufficiently distinct from the existing AVA and therefore appropriate for separate recognition. If the petition proposes the establishment of a new AVA that is larger than, and encompasses, all of one or more existing AVAs, the evidence submitted under paragraph (a) of this section must include information addressing whether, and to what extent, the attributes of the proposed AVA are consistent with those of the existing AVA(s). In any case in which an AVA would be created entirely within another AVA, whether by the establishment of a new, larger AVA or by the establishment of a new AVA within an existing one, the petition must explain why establishment of the AVA is acceptable. When a smaller AVA has name recognition and features that so clearly distinguish it from a larger AVA that surrounds it, TTB may determine in the course of the rulemaking that it is not part of the larger AVA and that wine produced from grapes grown within the smaller AVA would not be entitled to use the name of the larger AVA as an appellation of origin or in a brand name.
(c) Modification of an existing AVA -
(1) Boundary change. If a petition seeks to change the boundary of an existing AVA, the petitioner must include with the petition all relevant evidence and other information specified for a new AVA petition in paragraphs (a) and (b) of this section. This evidence or information must include, at a minimum, the following:
(i) Name evidence. If the proposed change involves an expansion of the existing boundary, the petition must show how the name of the existing AVA also applies to the expansion area. If the proposed change would result in a decrease in the size of an existing AVA, the petition must explain, if so, the extent to which the AVA name does not apply to the excluded area.
(ii) Distinguishing features. The petition must demonstrate that the area covered by the proposed change has, or does not have, distinguishing features affecting viticulture that are essentially the same as those of the existing AVA. If the proposed change involves an expansion of the existing AVA, the petition must demonstrate that the area covered by the expansion has the same distinguishing features as those of the existing AVA and has different features from those of the area outside the proposed, new boundary. If the proposed change would result in a decrease in the size of an existing AVA, the petition must explain how the distinguishing features of the excluded area are different from those within the boundary of the smaller AVA. In all cases the distinguishing features must affect viticulture.
(iii) Boundary evidence and description. The petition must explain how the boundary of the existing AVA was incorrectly or incompletely defined or is no longer accurate due to new evidence or changed circumstances, with reference to the name evidence and distinguishing features of the existing AVA and of the area affected by the proposed boundary change. The petition must include the appropriate U.S.G.S. maps with the proposed boundary change drawn on them and must provide a detailed narrative description of the changed boundary.
(2) Name change. If a petition seeks to change the name of an existing AVA, the petition must establish the suitability of that name change by providing the name evidence specified in paragraph (a)(1) of this section.
