SUPPLEMENTARY INFORMATION:
Background
On August 23, 1978, ATF published Treasury Decision ATF-53 (43 FR
37672, 54624) revising regulations in 27 CFR part 4. These regulations
allow the establishment of definitive viticultural areas. The
regulations allow the name of an approved viticultural area to be used
as an appellation of origin on wine labels and in wine advertisements.
On October 2, 1979, ATF published Treasury Decision ATF-60 (44 FR
56692) which added a new part 9 to 27 CFR, for the listing of approved
American viticultural areas, the names of which may be used as
appellations of origin.
Section 4.25a(e)(1), title 27, CFR, defines an American
viticultural area as a delimited grape-growing region distinguishable
by geographic features, the boundaries of which have been delineated in
subpart C of part 9.
Section 4.25a(e)(2) outlines the procedure for proposing an
American viticultural area. Any interested person may petition ATF to
establish a grape-growing region as a viticultural area. The petition
should include:
(a) Evidence that the name of the proposed viticultural area is
locally and/or nationally known as referring to the area specified in
the petition;
(b) Historical or current evidence that the boundaries of the
viticultural area are as specified in the petition;
(c) Evidence relating to the geographical characteristics (climate,
soil, elevation, physical features, etc.) which distinguish the
viticultural features of the proposed area from surrounding areas;
(d) A description of the specific boundaries of the viticultural
area,
[[Page 34028]]
based on features which can be found on United States Geological Survey
(U.S.G.S.) maps of the largest applicable scale; and
(e) A copy (or copies) of the appropriate U.S.G.S. map(s) with the
boundaries prominently marked.
Petition
The Bureau of Alcohol, Tobacco and Firearms (ATF) has received a
petition proposing the establishment of a viticultural area located in
the western foothills of Stanislaus County, California to be known as
``Diablo Grande.'' The petition was submitted by Dr. Vincent E.
Petrucci, Sc.D., on behalf of the Diablo Grande Limited Partnership,
the principal property owner within the proposed viticultural area and
developers of the Diablo Grande Resort Community. The proposed area
occupies over 45 square miles, or approximately 30,000 acres. According
to the petitioner, currently there are 35 acres of grapes planted with
an additional 17 acres planned for 1997. The petitioner claims that the
proposed area can accommodate an additional 2700 acres of future grape
plantings.
Evidence That the Name of the Area is Locally or Nationally Known
According to the petitioner, the name, ``Diablo Grande,'' has been
given to this proposed viticultural area because of its proximity to
Mount Diablo, the highest mountain peak of the Pacific Coast mountain
range. The petitioner claims that the name, ``Diablo Grande,'' has
become well-known to the residents of California, and perhaps the
nation, because of a multitude of newspaper articles regarding
development of the destination resort and residential community in the
proposed viticultural area. The resort community has been in existence
since the early 1990s. To support the name, the petitioner provided
copies of 21 newspaper articles. With the exception of the Golf Course
Report, Alexandria, Virginia, all of the articles are from local
California newspapers. These articles discuss the development of the
resort and the difficulties encountered by the developers in obtaining
approval for, and completion of, construction.
There is, however, some evidence that the area occupied by the
resort was historically known as the ``Oak Flats Valley.'' Many of the
articles submitted by the petitioner refer to the area as the ``Oak
Flats Valley Ranch'' or the ``Oak Flats Valley.'' No evidence was
provided that the area was tied to Mount Diablo prior to the
development of the resort. It should be noted that Mount Diablo is
several counties north of Stanislaus County, the location of the
proposed area. Therefore, despite the fact the petitioner submitted
some evidence justifying the use of the name ``Diablo Grande'' for the
proposed area, ATF is soliciting comments on the propriety of using
this name.
Historical or Current Evidence That the Boundaries of the Viticultural
Area Are as Specified in the Petition
As evidence that the boundaries of the proposed viticultural area
are as specified in the petition, the petitioner submitted a map
titled, ``Stanislaus County Vicinity Map'' drawn by Thompson-Hysell
Engineers. The petitioner also submitted a newspaper article from The
Modesto Bee dated June 28, 1993, showing the boundary area (map) in
respect to Interstate Highway 5, the city of Patterson, the City of
Newman, and the Santa Clara County line. The border for ``Diablo
Grande'' illustrated on the ``Stanislaus County Vicinity Map'' and the
maps in the newspaper article are non specific, giving the general
location within Stanislaus County, California. The Modesto Bee article
describes the site as being located about five miles west of Interstate
5 and seven miles southwest of Patterson consisting of gently sloping
hills to steep ridges in the Diablo Range, an eastern arm of the Coast
Ranges. The article further describes the site as encompassing portions
of three major watersheds--Orestimba, Crow, and Salado Creeks.
Evidence Relating to the Geographical Features (Climate, Soil,
Elevation, Physical Features, etc.) Which Distinguish Viticultural
Features of the Proposed Area From Surrounding Areas
Climate
According to the petitioner, in December, 1990, an automata weather
station was installed at the ``Diablo Grande'' test vineyard site by
Dr. Charles F. Krauter, professor of soils and water in the Department
of Plant Science, California State University, Fresno, California. The
recorded data from the weather station includes temperature (maximum,
minimum, average, and degree days), rainfall, humidity, solar
radiation, wind (speed and direction), and evapotranspiration rate.
The petitioner states that while the above parameters of climate
are very important, wine grape regions have been classified according
to heat summation units called degree days. The petitioner provided a
table of heat summation in degree days illustrating the contrast in
temperature between the proposed viticultural area and areas
immediately outside the proposed area. The data was taken from four
separate weather stations located in Newman (10 miles east), Westley
(10 miles north), Tracy (25 miles north) and Modesto (30 miles
northeast). The petitioner chose these areas because they were the
closest areas with climate records. According to the table, ``Diablo
Grande'' is 384 degree days warmer than Modesto, 191 degree days cooler
than Newman, 243 degree days cooler than Tracy, and 1022 degree days
cooler than Westley. Based on this data the petitioner claims that the
grapes from the proposed viticultural area would mature slightly
earlier than those grown in Modesto and would mature slightly later
than grapes grown in Newman, Westley, or Tracy.
The petitioner has submitted a four year record of rainfall
spanning from 1992 to 1995 for the proposed viticultural area. The
petitioner provided a table illustrating the contrast in monthly and
annual rainfall in inches between the proposed area and areas
immediately outside of the proposed area. The rainfall data shows that
the proposed area has an annual rainfall 13.8% to 22.6% higher than the
other four areas (Newman, Westley, Modesto, and Tracy). The petitioner
claims that the higher rainfall in the proposed viticultural area is
due to its higher elevation (800 to 2600 feet) as compared to the other
four areas which range in elevation from 40 to 300 feet. According to
the petitioner, rainfall generally occurs during the winter in all five
areas, with little or no rainfall during the summer months.
According to the petitioner, due to its elevation and the
protective mountains, the proposed area lies above the fog belt in
contrast with areas immediately outside of the proposed area. In the
Newman, Patterson, and Westley areas, fog is a common occurrence
throughout the rainy season in all but the foothill regions. The
petitioner claims that the absence of fog in the proposed area is a
unique feature which promotes a much higher quantity of solar radiation
resulting in the rate of photosynthesis being maximized providing for
better vine growth and a greater leaf canopy surface.
According to the petitioner, the predominant wind directions are
from northeast to northwest in the proposed viticultural area due to
the orientation of the many mini-valleys encompassing the area and the
wind deflection caused by the hills surrounding these mini-valleys. The
petitioner claims that this is a unique feature of the proposed
viticultural area's micro-climate as
[[Page 34029]]
contrasted with the Newman/Westley areas where the reverse is true with
the predominant winds coming from the northwest, typical of the flat
lands outside of the proposed viticultural area's perimeter.
Soils
According to the petitioner, the soil characteristics of the
proposed viticultural area are not only different and distinct from
those of the lower foothills and Central Valley to the east and north,
but they are also different from other areas of the Diablo Range to the
south and west of the proposed viticultural area.
The petitioner provided a general description of the soils in the
form of a report entitled, ``Diablo Grande Specific Plan Draft
Environmental Impact Report'' prepared by LSA Associates, Inc., Pt.
Richmond, California for the Stanislaus County Department of Planning
and Community Development. The petitioner also submitted a report from
the Soil Conservation Service which recently mapped soils within the
proposed viticultural area and identified 16 major soil types.
Finally, the petitioner states that extensive soil sampling and
detailed analysis (both physical and chemical) have been conducted at
two different locations within the proposed viticultural area.
According to the petitioner, in December of 1989, thirteen samples were
taken at various sites in the vicinity of the Oak Flat Ranch. In May of
1996, fourteen samples from Isom Ranch were collected and analyzed. A
copy of these analysis was included with the petition.
The petitioner claims that these reports show that a majority of
the soils found in the proposed viticultural area are composed of the
following series listed in approximate order of occurrence: Arburua
loam, Wisflat sandy loam, Contra Costa clay loam, and San Timoteo sandy
loam, with lesser amounts of Zacharias clay loam and gravelly clay
loam. According to the petitioner, most of the soils are complexes made
up of two or more of these series as well as occasional rock outcrops
of exposed sandstone and shale. The petitioner claims that in these
complexes, the soil series are so intimately intermixed that it is not
practical to separate them geographically.
The petitioner asserts that the reports show that the soils within
the proposed viticultural area typically have slopes ranging from 30%
to 75% and elevations from 400 to 2700 feet. An exception is the
relatively minor Zacharias series which has slopes of 2% to 5% and
elevations of 200 to 400 feet. The soils in the proposed viticultural
area are derived from sandstone and vary from shallow to very deep with
most of the complexes showing moderate depth. The soils are well-
drained to somewhat excessively-drained. Permeability varies from slow
to moderately rapid, surface run-off rates are rapid and, according to
the petitioner, the potential for water erosion can be severe. The
petitioner provided a table giving a complete description of the
characteristics for each soil type.
In contrast to the soils of the proposed viticultural area, the
petitioner claims that the soils of the surrounding areas are largely
composed of different soil series with different characteristics,
including elevations and slopes. The petitioner provided an exhibit
defining the various soil series and soil types, and an exhibit with
aerial photographic maps showing soil type location by map numbers.
While most of the soil series which are found within the proposed
viticultural area can also be found in the nearby surrounding areas,
the petitioner claims that these series represent very small portions
of the total in those surrounding areas. Additionally, the petitioner
states that many of the soil series which make up the major soil types
of the surrounding areas are not found at all within the proposed area.
The petitioner states that these soil types include Capay clay,
Vernalis clay loam, Stomar clay loam, Chaqua clay loam, Calla clay
loam, Carbona clay, Alo clay, Vaquero clay, El Salado loam and fine
sandy loam. According to the petitioner, these series are found to the
east and north of the proposed viticultural area. The petitioner states
that most of these series have slopes of 0% to 2% and elevations of 25
to 400 feet with four of these series having slopes up to 8%, 15%, 30%,
and 50% respectively and elevations from 300 to 1600 feet.
The petitioner states that there is another major difference
between the proposed viticultural area soils and most of those to the
east and north. The ``Diablo Grande'' soils are residual soils formed
from sedimentary deposits of sandstone and calcareous sandstone while
most of the surrounding soils are from alluvial deposits of mixed rock
parent material having lower slopes and elevations.
According to the petitioner, the area surrounding the proposed
viticultural area to the west and south includes the Orestimba Creek
Canyon beyond which lies a more rugged portion of the Diablo Range.
Much of the land directly west of the proposed area is part of the
Henry W. Coe State Park and although this area includes some of the
same soil series as the proposed area, there are also many new series
including Gonzaga clay, Honker clay, Franciscan clay loam, Vellecitos
clay, Gaviota gravelly loam, Henneke clay, Hentine loam, and Hytop
clay. The petitioner states that these soils generally have slopes of
30% to 75% and elevations of 700 to 3300 feet.
According to the petitioner, the results of these soil analyses and
the characteristics of the soil types found in the proposed
viticultural area, in combination with the climate and topography and
the use of drip irrigation, not only make the proposed viticultural
area suitable for the production of wine grapes but also make it a
unique and singular viticultural area which is completely distinctive
from the surrounding area.
Topography
According to the petitioner, the geography of the proposed
viticultural area sets it apart from the surrounding areas in several
respects. Three main water courses traverse the area: Salado Creek,
Crow Creek, and Orestimba Creek. Salado and Crow Creek traverse the
area from the vicinity of Mikes Peak along the western boundary of the
proposed area, northeast and east respectively, toward Interstate 5.
Orestimba Creek traverses the southwestern and southern boundary line
as it flows eastward.
The petitioner claims that current vineyard plantings are at
elevations ranging from 1000 feet msl near the vineyard located in the
vicinity of the Oak Flat Ranch to 1800 feet msl at the Isom Ranch. The
petitioner states that these vineyard site elevations are the highest
elevations where grapes are grown in Stanislaus County. The petitioner
contrasts this with other Stanislaus County vineyards outside the
proposed area where grapes are grown at elevations ranging from 70 to
90 feet at Modesto to 300 to 340 feet at the base of the foothills near
Patterson where a newly planted vineyard (1996) of 90 acres exists
approximately 4.2 miles east of the proposed viticultural area
boundary. The petitioner distinguishes this vineyard site from the
proposed viticultural area by noting that the Patterson site is 340
feet lower and has a soil type which is all Vernalis-Zacharias complex
with 0% to 2% slopes. The petitioner claims that these conditions do
not exist in the proposed viticultural area.
The petitioner also notes that the topographic features of the
proposed viticultural area include many ``mini-
[[Page 34030]]
valleys'' as a result of its mountainous structure. The petitioner
states that this provides several attributes not found in the vineyards
planted on the flat lands in the interior of Stanislaus County. Grapes
grown on the terraced hillsides of the proposed area are subject to a
mesoclimate (or topoclimate or site climate) which can vary from the
general macroclimate due to differences mainly in elevation and slope.
Thus, according to the petitioner, site selection becomes an important
feature when working with this type of topography as contrasted to the
flat lands of 1% to 2% slopes. According to the petitioner, there is
the opportunity to grow grapes on slopes (15%-30%) that have western,
eastern, southern, or northern exposure or any combination of all four
slope exposures.
According to the petitioner, while degree days associated with a
macroclimate may be similar to that of a mesoclimate, it is the makeup
of the mesoclimate of the proposed viticultural area that makes its
climate different from that of the surrounding areas. The petitioner
provided a diagram purporting to show how mesoclimates are influenced
by sloping contour topography. According to the petitioner, the
southern and western slopes receive a greater exposure to sunshine and,
therefore, accumulate more heat units than the northern or eastern
slopes. The petitioner claims that it is this difference in sunshine
and heat that makes the proposed viticultural area's mesoclimate.
According to the petitioner, grapes grown on all four slope exposures,
when harvested together and crushed as one lot, make wines that differ
considerably from grapes grown on the lower elevation flat lands. The
petitioner claims that this is the key factor which makes the proposed
viticultural area wines distinct from those of the surrounding area. In
support of this claim the petitioner provided several letters from
staff members at the Viticulture and Enology Research Center,
California State University, Fresno and winemakers. These letters
indicate that wines made from grapes grown in the proposed viticultural
area exhibit characteristics distinctive enough to deserve
consideration for a specific appellation.
Boundaries
The boundary of the proposed viticultural area may be found on four
United States Geological Survey Quadrangle 7.5 minute series
(Topographic) maps, entitled Patterson Quadrangle, California--
Stanislaus Co., Copper Mtn. Quadrangle, California--Stanislaus Co.,
Wilcox Ridge, California, Stanislaus Co., and Orestimba Peak,
California--Stanislaus Co.
Public Participation--Written Comments
ATF requests comments from all interested persons. Comments
received on or before the closing date will be carefully considered.
Comments received after that date will be given the same consideration
if it is practical to do so. However, assurance of consideration can
only be given to comments received on or before the closing date.
ATF is particularly interested in comments concerning the propriety
of using the name ``Diablo Grande'' for this proposed viticultural area
since there appears to be no evidence that this name was associated
with this area prior to the construction of the resort.
ATF will not recognize any submitted material as confidential and
comments may be disclosed to the public. Any material which the
commenter considers to be confidential or inappropriate for disclosure
to the public should not be included in the comments. The name of the
person submitting a comment is not exempt from disclosure.
Comments may be submitted by facsimile transmission to (202) 927-
8602, provided the comments: (1) are legible; (2) are 8\1/2\'' x 11''
in size, (3) contain a written signature, and (4) are three pages or
less in length. This limitation is necessary to assure reasonable
access to the equipment. Comments sent by FAX in excess of three pages
will not be accepted. Receipt of FAX transmittals will not be
acknowledged. Facsimile transmitted comments will be treated as
originals.
Any person who desires an opportunity to comment orally at a public
hearing on the proposed regulation should submit his or her request, in
writing, to the Director within the 60-day comment period. The
Director, however, reserves the right to determine, in light of all
circumstances, whether a public hearing will be held.
After consideration of all comments and suggestions, ATF may issue
a Treasury decision. The proposals discussed in this notice may be
modified due to comments and suggestions received.
Paperwork Reduction Act
The provisions of the Paperwork Reduction Act of 1995 (44 U.S.C.
3507 (j)) and its implementing regulations, 5 CFR part 1320, do not
apply to this notice because no requirement to collect information is
proposed.
Regulatory Flexibility Act
It is hereby certified that this proposed regulation will not have
a significant economic impact on a substantial number of small
entities. Any benefit derived from the use of a viticultural area name
is the result of the proprietor's own efforts and consumer acceptance
of wines from a particular area. No new requirements are proposed.
Accordingly, a regulatory flexibility analysis is not required.
Executive Order 12866
It has been determined that this proposed regulation is not a
significant regulatory action as defined in Executive Order 12866.
Accordingly, this proposal is not subject to the analysis required by
this Executive order.
