SUPPLEMENTARY INFORMATION:

Background on Viticultural Areas

TTB Authority

    Section 105(e) of the Federal Alcohol Administration Act (FAA Act), 
27 U.S.C. 205(e), authorizes the Secretary of the Treasury to prescribe 
regulations for the labeling of wine, distilled spirits, and malt 
beverages. The FAA Act provides that these regulations should, among 
other things, prohibit consumer deception and the use of misleading 
statements on labels, and ensure that labels provide the consumer with 
adequate information as to the identity and quality of the product. The 
Alcohol and Tobacco Tax and Trade Bureau (TTB) administers the 
regulations promulgated under the FAA Act.
    Part 4 of the TTB regulations (27 CFR part 4) allows the 
establishment of definitive viticultural areas and the use of their 
names as appellations of origin on wine labels and in wine 
advertisements. Part 9 of the TTB regulations (27 CFR part 9) contains 
the list of approved viticultural areas.

Definition

    Section 4.25(e)(1)(i) of the TTB regulations (27 CFR 4.25(e)(1)(i)) 
defines a viticultural area for American wine as a delimited grape-
growing region distinguishable by geographical features, the boundaries 
of which have been recognized and defined in part 9 of the regulations. 
These designations allow vintners and consumers to attribute a given 
quality, reputation, or other characteristic of a wine made from grapes 
grown in an area to its geographical origin. The establishment of 
viticultural areas allows vintners to describe more accurately the 
origin of their wines to consumers and helps consumers to identify 
wines they may purchase. Establishment of a viticultural area is 
neither an approval nor an endorsement by TTB of the wine produced in 
that area.

Requirements

    Section 4.25(e)(2) of the TTB regulations outlines the procedure 
for proposing an American viticultural area and provides that any 
interested party may petition TTB to establish a grape-growing region 
as a viticultural area. Section 9.3(b) of the TTB regulations requires 
the petition to include--
    <bullet> Evidence that the proposed viticultural area is locally 
and/or nationally known by the name specified in the petition;
    <bullet> Historical or current evidence that supports setting the 
boundary of the proposed viticultural area as the petition specifies;
    <bullet> Evidence relating to the geographical features, such as 
climate, elevation, physical features, and soils, that distinguish the 
proposed viticultural area from surrounding areas;
    <bullet> A description of the specific boundary of the proposed 
viticultural area, based on features found on United States Geological 
Survey (USGS) maps; and
    <bullet> A copy of the appropriate USGS map(s) with the proposed 
viticultural area's boundary prominently marked.

Snake River Valley Viticultural Area

Background

    The wine grape growers of the Snake River Valley in Idaho, the 
Idaho Grape Growers and Wine Producers Commission, and the Idaho 
Department of Commerce and Labor, collectively referred to as the 
``petitioner,'' submitted a petition to establish the 8,263-square mile 
Snake River Valley viticultural area. The proposed viticultural area 
includes Ada, Adams, Boise, Canyon, Elmore, Gem, Gooding, Jerome, 
Owyhee, Payette, Twin Falls, and Washington Counties in southwestern 
Idaho and Baker and Malheur Counties in southeastern Oregon. The 
proposed boundary encompasses 15 wineries, 46 vineyards, and 1,107 
acres of commercial vineyard production. We summarize below the 
supporting evidence presented with the petition.

Name Evidence

    The petitioner provided multiple sources of ``Snake River Valley'' 
name evidence for the proposed viticultural area. References include 
winemaking and vineyards, agriculture, early regional exploration, and 
other name uses.
    The Fall 2001 edition of Wine Press Northwest ran an article titled 
``Idaho Wineries at a Glance,'' which states, ``At first glance, the 
Snake River Valley seems an idyllic place to grow grapes

[[Page 10599]]

* * *'' and continues to explain that most of the grapes are grown in 
the Snake River Valley area west of Boise, Idaho. The February 17, 
2005, edition of Wine Press Northwest ran an article describing the 
Snake River Valley as a beautiful area in southwestern Idaho. The 
article noted that most of the Idaho wineries and vineyards are at 
elevations between 1,500 and 2,500 feet in the western portion of the 
Snake River Valley.
    The official Web site of the State of Idaho has a link to the 
history of Idaho, noting that in 1811 the Pacific Fur Company 
expedition explored the Snake River Valley and discovered the Boise 
Valley, which is within the boundary of the proposed viticultural area. 
An undated Sunset Magazine article, ``The Snake River Valley of Idaho-
Eastern Oregon,'' discusses the significant agricultural production in 
the Snake River Valley of Idaho and eastern Oregon.
    The USGS maps used to identify the proposed Snake River Valley 
viticultural area prominently show the Snake River at the low 
elevations of the proposed viticultural area. The American Automobile 
Association Western States/Provinces map, dated February 2003 through 
May 2005, shows the Snake River flowing from its headwaters in Wyoming, 
through Idaho and Oregon, and into Washington to where it joins the 
Columbia River near Pasco and Kennewick.

Boundary Evidence

    The proposed Snake River Valley viticultural area covers portions 
of southwestern Idaho and southeastern Oregon. The basis for the 
proposed boundaries, the petitioner explains, is the extent of ancient 
Lake Idaho, a deep lake that filled the western part of the Snake River 
Valley approximately 4 million years ago. The proposed boundary line, 
with a maximum elevation of 1,040 meters, or 3,412 feet, surrounds the 
now dry, ancient Lake Idaho at the highest elevation conducive to 
viticulture, according to the petitioner.
    The Snake River Plain, a crescent-shaped belt of lava and sediment 
ranging from 40 to 62 miles wide, extends about 372 miles in length 
across southern Idaho, according to the petitioner. The geology of the 
western portion of the Snake River Plain, the petitioner continues, has 
lower elevations and a rift-bounded basin, which contrast to the higher 
elevations of the eastern section of the Snake River Plain. Also, 
according to the petitioner, the colder and drier climate of the 
eastern area is not conducive to successful viticulture, unlike the 
warmer weather and lower elevations of ancient Lake Idaho.
    An April 21, 1997, article, ``Hydrogeologic Framework of the Boise 
Valley of Southwest Idaho,'' by Spencer H. Wood, Department of 
Geosciences, Boise State University, describes the Snake River Plain as 
a great geologic bathtub with layers of mud sediment and interconnected 
layers of sand. According to the article, the depth of the basin plain 
averages 3,500 feet but extends to 6,000 feet. Also, in prehistoric 
times ancient Lake Idaho was 800 feet deep in places and covered 5,000 
square miles. Today, this region is a flat, semiarid plain that is 
irrigated for agriculture with water from the Boise River and with 
ground water, according to the article.

Distinguishing Features

    The proposed Snake River Valley viticultural area includes a series 
of distinguishing features. According to the petitioner its topography 
includes elevations lower than the surrounding areas and a fault-
bounded, rift basin geography. Also, the area is primarily underlain by 
sedimentary rock. The comparatively warm climate of the proposed Snake 
River Valley viticultural area creates better grape-growing conditions 
than those in the surrounding higher elevations and the Snake River 
Valley in eastern Idaho.
Geology
    The petitioner states that the geologic history of the proposed 
Snake River Valley viticultural area includes flood basalts, northwest-
trending structures, loess mantles, and outburst floods. The ancient 
Lake Idaho extends 149 miles northwest to southeast as a system of 
lakes and flood plains, from the Oregon-Idaho State line to west of 
Twin Falls, Idaho.
    North of the proposed Snake River Valley viticultural area boundary 
line, the petitioner explains, are Cretaceous granites of the Idaho 
Batholith, Eocene volcanoes, older sedimentary rocks, and volcanic 
flows. To the south of the proposed boundary line, volcanic rocks 
overlie the southern extension of the granite basement.
Regional Summary
    The petitioner includes a map of the Snake River Plain Aquifer 
System and information modified from the ``Ground Water Atlas of the 
United States: Idaho, Oregon, Washington, U.S. Geological Survey 
Hydrologic Atlas HA 730-H, 1994.'' The map shows that the Western 
Plain, which is within the proposed Snake River Valley viticultural 
area, is underlain by aquifers in basaltic rock but mainly in 
unconsolidated (sedimentary) deposits. In contrast, the Eastern Plain, 
to the east of the proposed Snake River Valley viticultural area, is 
underlain predominantly by aquifers in Pliocene and younger basaltic 
rocks.
    The petitioner includes a second map that documents the 
distribution of rock types in the Pacific Northwest States, based on 
information taken from the same USGS Hydrologic Atlas noted above. The 
proposed Snake River Valley viticultural area, according to the map, is 
underlain primarily by sedimentary rocks, distinguishing the area from 
basaltic and other igneous rocks in the surrounding regions.
Geography
    Physical Features: The petitioner describes the ancient Lake Idaho 
as the physical focus and an important distinguishing feature of the 
proposed Snake River Valley viticultural area. Historically, the 
ancient Lake Idaho was a trough-like structure of lakes. The proposed 
Snake River Valley viticultural area boundary encircles the now dry, 
ancient Lake Idaho, a low elevation, fault-bounded, rift basin with a 
relatively flat, sedimentary bottom. The surrounding areas, beyond the 
proposed boundary, have a mountainous topography with generally higher 
elevations.
    Elevation: Low elevation, between 660 and 1,040 meters, or 2,165 
and 3,412 feet, when compared to the surrounding mountains and the 
eastern portion of the Snake River Valley, is a significant 
distinguishing feature of the proposed Snake River Valley viticultural 
area, as shown on the USGS maps and described by the petitioner. Oxbow 
Dam, along the Snake River in Adams County, Idaho, lies at an elevation 
of 660 meters, or 2,165 feet, but the encircling proposed viticultural 
area boundary line generally adheres to an elevation of 1,040 meters, 
or 3,412 feet, according to the boundary outlined in the petition. The 
proposed boundary line deviates from its prescribed 1,040-meter 
elevation twice at the northernmost boundary on the McCall map and 
again along the western boundary of the Vale map. The petitioner 
explains that the 1,040-meter contour line, past the boundaries of the 
McCall and Vale maps, continues into regions not associated with the 
Snake River Valley or with viticulture. The region's viticulture, 
according to the petitioner, is successful between elevations of 664 
and 950 meters, or 2,180 and 3,117 feet.

[[Page 10600]]

    Mountains surrounding the western Snake River Valley region exceed 
7,000 feet in elevation, especially to the east of the proposed 
viticultural area boundary line in the Boise National Forest, as shown 
on the Idaho City, Idaho, USGS map. The City of Twin Falls, Idaho, 
about 2\1/2\ miles southeast of the proposed Snake River Valley 
viticultural area's eastern boundary line, as shown on the USGS Twin 
Falls, Idaho, map, lies at an elevation of 3,729 feet, or about 320 
feet higher than the elevation of the proposed viticultural area 
boundary line.
    The petitioner provides three topographic profiles of the proposed 
Snake River Valley viticultural area drawn from various points of the 
compass. The three profiles include (1) California Mountain, Oregon, to 
Bruneau, Idaho, (2) Oreana, Idaho, to Danskin Peak, Idaho, and (3) 
Marsing, Idaho, to Emmett, Idaho. The profiles show the lower 
elevations of the ancient Lake Idaho basin in comparison to the 
surrounding higher mountain elevations beyond the proposed viticultural 
area boundary line. Payette, Idaho, is at an elevation of about 2,300 
feet in the basin, but California Mountain, Oregon, reaches a height of 
approximately 5,150 feet, significantly higher than the proposed 
viticultural area boundary line.
Soils
    The petitioner describes the soils of the proposed Snake River 
Valley viticultural area as being diverse and not a distinguishing 
feature, because the soils have developed in various parent materials, 
during various time frames, and under varying climatic conditions. The 
soils are broadly classified as Aridisols, the petitioner adds, and no 
single soil series or association is dominant.
    Vineyards within the proposed Snake River Valley viticultural area 
are on soils that have underlying parent material derived from 
weathered sediment from the ancient Lake Idaho, according to the 
petitioner. At the surface are loess, sand, and, in slack water areas, 
flood-deposited silt. Typically, vineyards in the proposed area are on 
very shallow soils on slopes.
Climate
    The distinguishing climatic features of the proposed Snake River 
Valley viticultural area, the petitioner states, include precipitation, 
air temperature, heat-unit accumulation, and growing season length. The 
factors affecting climate, the petitioner continues, include the 
region's topography, a basin depression with surrounding mountainous 
terrain; the continental inland location approximately 310 miles east 
of the Cascade Range; and the 43 degree north latitude line. The 
petitioner adds that the proposed Snake River Valley viticultural area 
is in a climatic transition zone with both continental and maritime 
regimes. The combination of elevation and latitude of the proposed 
Snake River Valley viticultural area, the petitioner continues, creates 
a shorter grape-growing season than those in many other viticultural 
regions in the Western United States.
    Climatic data from four weather stations in the West Snake River 
Valley (WSRV) and for other grape-growing districts in the Western 
United States are noted in the climatic data table below.
    The petitioner used online data from 1971 to 2000 compiled and 
archived by the National Climatic Data Center (NCDC), National Oceanic 
and Atmospheric Administration, for four areas within the proposed 
Snake River Valley viticultural area and for three viticultural regions 
outside of Idaho. The petitioner averaged the collected data for the 
four Idaho weather stations listed in the climatic data table below. 
The data are listed separately in the table for each station outside of 
Idaho, including Umpqua Valley, Oregon; Walla Walla Valley, Washington; 
and Napa Valley, California, all of which are in established American 
viticultural areas.

--------------------------------------------------------------------------------------------------------------------------------------------------------

    Precipitation: The proposed Snake River Valley viticultural area is 
a semiarid desert with minimal summer precipitation, the petitioner 
explains. The proposed viticultural area has a mean annual 
precipitation of 10 to 12

[[Page 10601]]

inches, occurring mostly in winter. The low precipitation rate combines 
with warm weather during the growing season, and the vineyards 
therefore need irrigation.
    According to the petitioner, the Idaho weather stations within the 
proposed Snake River Valley viticultural area record about half the 
annual precipitation of the weather stations at Umpqua Valley, Oregon; 
Walla Walla Valley, Washington; and Napa Valley, California. The 
petitioner explains that the lower annual precipitation of the proposed 
Snake River Valley viticultural area may be partially due to the rain 
shadows of the Cascade, Sierra Nevada, and Owyhee Ranges.
    Temperature: The proposed Snake River Valley viticultural area's 
mean annual temperature, based on an average of the four Idaho stations 
monitored, is 51 degrees F, or 10.8 degrees C. The midwinter mean 
temperatures are below 0 degrees C for several months, and potential 
vineyard damage is a hazard, the petitioner explains. The California, 
Oregon, and Washington weather stations listed in the climatic data 
table above record warmer average winter temperatures. The differences 
in the extreme winter temperatures and the mean annual temperature 
ranges between the proposed Snake River Valley viticultural area and 
the three weather stations monitored in California, Oregon, and 
Washington show significant variations in viticultural growing 
conditions.
    The petitioner explains that the difference in winter temperatures 
between the colder proposed Snake River Valley viticultural area and 
the stations at Umpqua Valley, Oregon; Walla Walla Valley, Washington; 
and Napa Valley, California, results, to a great extent, from the 
higher elevations in the proposed viticultural area, which are between 
660 and 1,040 meters, or 2,165 and 3,412 feet. Elevations of the other 
stations are Umpqua Valley, about 460 feet; Walla Walla Valley, 1,200 
feet; and Napa Valley, 40 feet.
    Also, distances from the Pacific Ocean affect the amount of 
moderating, marine air temperatures the seven weather stations receive. 
Oceans tend to moderate air temperatures over land; hence, a wider 
annual temperature range indicates a greater degree of continental 
influence, or distance from an ocean. The proposed Snake River Valley 
viticultural area and the Walla Walla Valley both have, as a measure of 
continental influence, mean annual temperature ranges of about 25 
degrees C. In comparison, the Umpqua Valley and the Napa Valley, both 
of which are closer to the Pacific Ocean and are at low elevations, 
have a smaller mean annual temperature range--about 15 degrees C.
    The temperatures of the proposed Snake River Valley viticultural 
area, according to the petitioner, rise rapidly during the growing 
season, from June through August. The Umpqua Valley in Oregon and the 
proposed Snake River Valley viticultural area have similar, annual, 
total growing degree-days, as shown in the climatic data table above; 
but, they have between 200 and 250 fewer heat units than the Walla 
Walla Valley, Washington, and the Napa Valley, California. Each degree 
that a day's mean temperature is above 50 degrees F, which is the 
minimum temperature required for grapevine growth, is counted as 1 
degree-day (see ``General Viticulture,'' Albert J. Winkler, University 
of California Press, 1975).
    The length of the proposed Snake River Valley viticultural area's 
growing season correlates to the frost-free period from about May 10 to 
September 29 annually, according to the petitioner. The total 
measurement of annual viticultural growth is between 64 and 117 days 
less than that measured at Walla Walla Valley, Washington; Umpqua 
Valley, Oregon; and Napa Valley, California.

Notice of Proposed Rulemaking and Comments Received

    TTB published Notice No. 60 regarding the proposed Snake River 
Valley viticultural area in the Federal Register on July 17, 2006 (71 
FR 40458). In that notice, TTB invited comments by September 15, 2006, 
from all interested persons. We expressed particular interest in 
receiving comments on whether the proposed area name would result in a 
conflict with currently used brand names. We also solicited comments on 
the appropriateness of the proposed eastern boundary line and asked 
whether the boundary should be extended into southeastern Idaho. 
Finally, we specifically solicited comments on the appropriateness of 
the name ``Snake River Valley'' and asked whether ``West Snake River 
Valley'' or another alternative name would be more appropriate for this 
area. We received three comments in response to that notice. All three 
comments supported the establishment of the Snake River Valley 
viticultural area as proposed.

TTB Finding

    After careful review of the petition and the comments received, TTB 
finds that the evidence submitted supports the establishment of the 
proposed viticultural area. Therefore, under the authority of the 
Federal Alcohol Administration Act and part 4 of our regulations, we 
establish the ``Snake River Valley'' viticultural area in southwestern 
Idaho and southeastern Oregon, effective 30 days from the publication 
date of this document.

Boundary Description

    See the narrative boundary description of the viticultural area in 
the regulatory text published at the end of this document.

Maps

    The maps for determining the boundary of the viticultural area are 
listed below in the regulatory text.

Impact on Current Wine Labels

    Part 4 of the TTB regulations prohibits any label reference on a 
wine that indicates or implies an origin other than the wine's true 
place of origin. With the establishment of this viticultural area and 
its inclusion in part 9 of the TTB regulations, its name, ``Snake River 
Valley,'' is recognized under 27 CFR 4.39(i)(3) as a name of 
viticultural significance. The text of the new regulation clarifies 
this point. Consequently, wine bottlers using ``Snake River Valley'' in 
a brand name, including a trademark, or in another label reference as 
to the origin of the wine, must ensure that the product is eligible to 
use the viticultural area's name as an appellation of origin. No single 
part of the ``Snake River Valley'' viticultural area name standing 
alone, such as ``snake'' or ``Snake River'', has viticultural 
significance. The word ``snake'' alone is not routinely identified with 
the ``Snake River Valley.'' The name ``Snake River'' applies to 13 
streams in 9 States, spanning from Florida to Alaska, according to the 
USGS Geographic Names Information System.
    For a wine to be labeled with a viticultural area name or with a 
brand name that includes a viticultural area name or other term 
specified as having viticultural significance in part 9 of the TTB 
regulations, at least 85 percent of the wine must be derived from 
grapes grown within the area represented by that name or other term, 
and the wine must meet the other conditions listed in 27 CFR 
4.25(e)(3). If the wine is not eligible to use the viticultural area 
name or other term of viticultural significance as an appellation of 
origin and that name or other term appears in the brand name, then the 
label is not in compliance and the bottler must change the brand name 
and obtain approval of a new label. Similarly, if the viticultural area 
name or other term of viticultural

[[Page 10602]]

significance appears in another reference on the label in a misleading 
manner, the bottler would have to obtain approval of a new label.
    Different rules apply if a wine has a brand name containing a 
viticultural area name or other term of viticultural significance that 
was used as a brand name on a label approved before July 7, 1986. See 
27 CFR 4.39(i)(2) for details.

Regulatory Flexibility Act

    We certify that this regulation will not have a significant 
economic impact on a substantial number of small entities. This 
regulation imposes no new reporting, recordkeeping, or other 
administrative requirement. Any benefit derived from the use of a 
viticultural area name is the result of a proprietor's efforts and 
consumer acceptance of wines from that area. Therefore, no regulatory 
flexibility analysis is required.

Executive Order 12866

    This rule is not a significant regulatory action as defined by 
Executive Order 12866, 58 FR 51735. Therefore, it requires no 
regulatory assessment.
