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 geographical 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, 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
Dr. Vincent E. Petrucci, Sc.D., petitioned ATF on behalf of the
Diablo Grande Limited Partnership, for the establishment of a new
viticultural area located in the western foothills of Stanislaus
County, California, to be known as ``Diablo Grande.'' The Diablo Grande
Limited Partnership is the principal property owner within the proposed
viticultural area and the developer of the Diablo Grande Resort
Community. The viticultural area occupies over 45 square miles, or
approximately 30,000 acres. Currently there are 35 acres of grapes
planted with an additional 17 acres planned for 1997. The petitioner
claims that the area can accommodate an additional 2700 acres of future
grape plantings.
Comments
A Notice of Proposed Rulemaking, Notice No. 853 (62 FR 34027) was
published in the Federal Register on June 24, 1997, requesting comments
from all interested persons concerning the proposed ``Diablo Grande''
viticultural area. No comments were received in response to this
notice.
Evidence That the Name of the Area Is Locally or Nationally Known
``Diablo Grande,'' is the name of the destination resort and
residential community that occupies the viticultural area. The
petitioner stated that this name was given to the area because of its
proximity to Mount Diablo, the highest peak of the Pacific Coast
mountain range. Mount Diablo is located 38-40 miles due north of the
proposed area. The petitioner emphasized the fact that the proposed
area lies in the Diablo Mountain Range, which extends from Mount Diablo
State Park in Contra Costa County to the south of and beyond the
proposed ``Diablo Grande'' viticultural area located in Stanislaus
County. There is evidence that the name, ``Diablo Grande,'' has become
associated with the area by both the residents of California, and
perhaps the nation, as a result of the development of the destination
resort and residential community. The resort community has been in
existence since the early 1990s. As evidence that the area is known as
``Diablo Grande,'' the petitioner submitted copies of 21 newspaper
articles that discuss the development of the resort. With the exception
of the Golf Course Report, Alexandria, Virginia, all of the articles
are from local California newspapers.
There is also evidence that the area occupied by the resort was
historically known as the ``Oak Flats Valley.'' A working ranch, known
as the Oak Flats Valley Ranch once occupied this land. Many of the
newspaper 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. Accordingly, ATF solicited comments in
Notice No. 853 on whether the use of the name ``Diablo Grande'' was
proper for this area. No comments were received on this issue.
Consequently, based on the evidence submitted by the petitioner, ATF
believes the name ``Diablo Grande'' is now associated with the area.
[[Page 33851]]
Historical or Current Evidence That the Boundaries of the
Viticultural Area Are as Specified in the Petition
As evidence that the boundaries of the viticultural area are as
specified in the petition, the petitioner submitted a map titled,
``Stanislaus County Vicinity Map'' drawn by Thompson-Hysell Engineers.
A more detailed map entitled ``Concept Plan Diablo Grande,'' prepared
by T.R.G. Land Resources, Inc., was also submitted. In addition, the
petitioner 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'' is illustrated on
the ``Stanislaus County Vicinity Map'' and the maps in the newspaper
article giving the 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 Area From Surrounding Areas
Climate
The petitioner provided a table of heat summation in degree days
illustrating the contrast in temperature between the viticultural area
and areas immediately outside the viticultural 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, the
``Diablo Grande'' viticultural area is 384 degree days warmer than
Modesto, 191 degree days cooler than Newman, 243 degree days cooler
that Tracy, and 1022 degree days cooler than Westley.
The petitioner submitted a four year record of rainfall spanning
from 1992 to 1995 for the viticultural area. The petitioner also
provided a table illustrating the contrast in monthly and annual
rainfall in inches between the ``Diablo Grande'' viticultural area and
areas immediately outside of the viticultural area. The rainfall data
shows that the ``Diablo Grande'' viticultural area has an annual
rainfall 13.8% to 22.6% higher that the other four areas (Newman,
Westley, Modesto, and Tracy). The higher rainfall in the 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.
Rainfall generally occurs during the winter in all five areas, with
little or no rainfall during the summer months.
Due to its elevation and the protective mountains, the viticultural
area lies above the fog belt in contrast with areas immediately outside
of the viticultural area. In the Newman, Patterson, and Westley areas,
fog is a common occurrence throughout the rainy season in all but the
foothill regions.
The predominant wind directions are from northeast to northwest in
the ``Diablo Grande'' 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. This is a unique feature
of the viticultural area's micro-climate as 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
viticultural area's perimeter.
Soils
The soil characteristics of the ``Diablo Grande'' 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
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
viticultural area and identified 16 major soil types.
Extensive soil sampling and detailed analysis (both physical and
chemical) have been conducted at two different locations within the
viticultural area. 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
this analysis was included with the petition.
These reports show that a majority of the soils found in the
``Diablo Grande'' 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. 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. In these
complexes, the soil series are so intimately intermixed that it is not
practical to separate them geographically.
The reports show that the soils within the 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 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 viticultural area, 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 ``Diablo
Grande'' viticultural area can also be found in the nearby surrounding
areas, these series represent very small portions of the total in those
surrounding areas. Additionally, many of the soil series which make up
the major soil types of the surrounding areas are not found at all
within the viticultural area. 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. These series are found to the east and north of the
viticultural area. 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.
There is another major difference between the ``Diablo Grande''
[[Page 33852]]
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.
The area surrounding the ``Diablo Grande'' 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 viticultural area is part of the Henry W. Coe State Park and
although this area includes some of the same soil series as the
``Diablo Grande'' viticultural 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. These soils generally have slopes of 30% to 75% and elevations of
700 to 3300 feet.
Topography
The geography of the 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 viticultural area, northeast and east
respectively, toward Interstate 5. Orestimba Creek traverses the
southwestern and southern boundary line as it flows eastward.
Current vineyard plantings are at elevations ranging from 1000 feet
mean sea level (msl) near the vineyard located in the vicinity of the
Oak Flat Ranch to 1800 feet msl at the Isom Ranch. These vineyard site
elevations are the highest elevations where grapes are grown in
Stanislaus County. This contrasts with other Stanislaus County
vineyards outside the ``Diablo Grande'' viticultural 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 viticultural area boundary. The petitioner distinguishes this
vineyard site from the ``Diablo Grande'' 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. These conditions
do not exist in the ``Diablo Grande'' viticultural area.
The topographic features of the viticultural area include many
``mini-valleys'' as a result of its mountainous structure. 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 viticultural 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, site selection becomes an important feature when working with
this type of topography as contrasted to the flat lands of 1% to 2%
slopes. 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.
The petitioner provided a diagram purporting to show how
mesoclimates are influenced by sloping contour topography. The southern
and western slopes receive a greater exposure to sunshine and,
therefore, accumulate more heat units than the northern or eastern
slopes. It is this difference in sunshine and heat that makes the
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 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 ``Diablo Grande'' viticultural area exhibit characteristics
distinctive enough to deserve consideration for a specific appellation.
ATF has concluded that there is sufficient evidence to establish the
``Diablo Grande,'' area as a distinct viticultural area under 27 CFR
part 9.
Geographic Brand Names
A brand name of viticultural significance may not be used unless
the wine meets the appellation of origin requirements for the
geographic area named. See 27 CFR 4.39(i). Consequently, establishment
of this viticultural area would preclude the use of the term ``Diablo
Grande'' as a brand name for a wine, unless the wine can claim ``Diablo
Grande'' as an appellation of origin, or complies with one of the
exceptions in the regulation.
Boundaries
The boundary of the ``Diablo Grande'' 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.
Paperwork Reduction Act
The provisions of the Paperwork Reduction Act of 1995, 44 U.S.C.
Chapter 35, and its implementing regulations, 5 CFR part 1320, do not
apply to this final rule because no requirement to collect information
is imposed.
Regulatory Flexibility Act
It is hereby certified that this regulation will not have a
significant economic impact on a substantial number of small entities.
The establishment of a viticultural area is neither an endorsement nor
approval by ATF of the quality of wine produced in the area, but rather
an identification of an area that is distinct from surrounding areas.
ATF believes that the establishment of viticultural areas merely allows
wineries to more accurately describe the origin of their wines to
consumers, and helps consumers identify the wines they purchase. Thus,
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 imposed. Accordingly, a
regulatory flexibility analysis is not required.
Executive Order 12866
It has been determined that this regulation is not a significant
regulatory action as defined in Executive Order 12866. Accordingly,
this final rule is not subject to the analysis required by this
Executive Order.
