(a) Name. The name of the viticultural area described in this section is “Lower Long Tom”. For purposes of part 4 of this chapter, “Lower Long Tom” is a term of viticultural significance.

(b) Approved maps. The four United States Geological Survey (USGS) 1:24,000 scale topographic maps used to determine the boundary of the Lower Long Tom viticultural area are titled:

(1) Cheshire, Oregon, 1984;

(2) Horton, Oregon, 1984;

(3) Glenbrook, Oregon, 1984; and

(4) Monroe, Oregon, 1991.

(c) Boundary. The Lower Long Tom viticultural area is located in Benton and Lane Counties, in Oregon. The boundary of the Lower Long Tom viticultural area is as described as follows:

(1) The beginning point is on the Cheshire map at the intersection of Franklin Road and the 360-foot elevation contour in Section 43, T16S/R5W. From the beginning point, proceed west on Franklin Road to its intersection with Territorial Road (known locally as Territorial Highway); then

(2) Proceed southwesterly along Territorial Highway to its intersection with an unnamed, unimproved road north of Butler Road in Section 44, T16S/R5W; then

(3) Proceed west in a straight line to the western boundary of Section 29, T16S/R5W; then

(4) Proceed north along the western boundary of Section 29 to the southern boundary of Section 57, T16S/R5W; then

(5) Proceed northwest in a straight line to the right angle in the western boundary of Section 57, T16S/R5W; then

(6) Proceed west in a straight line, crossing through Sections 58 and 38, to the intersection of Sections 23, 24, 25, and 26, T16S/R6W; then

(7) Proceed north along the western boundary of Section 24 to the first intersection with the 800-foot elevation contour; then

(8) Proceed northerly, then northwesterly along the 800-foot elevation contour, crossing onto the Horton map, to the intersection of the 800-foot elevation contour and an unnamed, unimproved road with a marked 782-foot elevation point in Section 10, T16S/R6W; then

(9) Proceed west in a straight line to the 1,000-foot elevation contour; then

(10) Proceed northerly along the 1,000-foot elevation contour, crossing onto the Glenbrook map, to the elevation contour's third intersection with the Lane-Benton County line in Section 10, T15S/R6W; then

(11) Proceed east along the Lane-Benton County line, crossing onto the Monroe map, to the R6W/R5W range line; then

(12) Proceed north along the R6W/R5W range line to its intersection with Cherry Creek Road; then

(13) Proceed northeasterly along Cherry Creek Road to its intersection with Shafer Creek along the T14S/T15S township line; then

(14) Proceed northeasterly along Shafer Creek to its intersection with the 300-foot elevation contour; then

(15) Proceed easterly along the 300-foot elevation contour, crossing Territorial Highway, to the intersection of the elevation contour with the marked old railroad grade in Section 33/T14S/R5W; then

(16) Proceed south along the old railroad grade to its intersection with the southern boundary of Section 9, T15S/R5W; then

(17) Proceed west along the southern boundary of Section 9 to its intersection with Territorial Highway; then

(18) Proceed south along Territorial Highway to its intersection with the 360-foot elevation contour in Section 16; T15S/R5W; then

(19) Proceed southwesterly along the 360-foot elevation contour, crossing Ferguson Creek, and continuing generally southeasterly along the elevation contour, crossing onto the Cheshire map and crossing over Owens Creek and Jones Creek, to the point where the elevation contour crosses Bear Creek and turns north in Section 52; T16S/R5W; then

(20) Continue northeasterly along the 360-foot elevation contour to the point where it turns south in the town of Cheshire; then

(21) Continue south along the 360-foot elevation contour and return to the beginning point.
