The Telluride nonattainment area begins at the intersection of Colorado State Highway 145 and the Telluride service area boundary, as it existed in 1991. The western edge of the nonattainment area until it meets Remine Creek is defined as follows: A tract of land located in a portion of the west one-half of Section 28 and the east one-half of Section 29, Township 43 North, Range 9 west, of the New Mexico Principal Meridian, County of San Miguel, State of Colorado, described as follows: Beginning at the southwest corner of the said Section 28; Thence N 89°36′00′′ W. 292.70 Feet; Thence S 04°05'12" W. 538.63 Feet; Thence N 03°29′42′′ W. 780.19 Feet; Thence N 22°15′00′′E. 3344.16 Feet; Thence S 51°51′49′′ E. 570.44 Feet; Thence S 03°15′36′′ E. 1106.22 Feet; Thence S 45°24′42′′ E. 546.96 Feet; Thence S 28°41'12" W. 549.62 Feet; Thence S 29°40′09′′" E. 169.68 Feet; Thence S 44°30′03′′ W. 649.51 Feet; Thence S 85°54′00′′ E. 660.00 Feet; Thence S 04°06′00′′ W. 660.00 Feet; Thence N 89°56′00′′ E. 1318.68 Feet; to the true point of beginning containing 11249 acres as described above.

Then, at Remine Creek, the nonattainment bound-
ary follows the service area boundary for 9.65
miles to the 9,200 foot contour line. The bound-
ary then intersects Bear Creek. Here the non-
attainment boundary diverges from the service
area boundary (9,200 foot contour line). The
nonatttainment boundary continues in a west,
southwest direction for 0.92 miles from the inter-
section of the 9,200 foot contour line and Bear
Creek to the top of ski lift number 9 in the Tellu-
ride Ski Area at an elevation of about 11,900
feet. The boundary then shifts and runs in a
north-westerly direction for 0.83 miles from the
top of lift 9 to the top of lift 7, which is located at
an elevation of 10,490 feet. From the top of lift 7,
the nonattainment boundary continues in a north-
westerly direction for 0.5 miles to the intersection
of lift 3 with the 10,000 foot control line. The non-
attainment boundary follows the 10,000 foot con-
tour line in a south, south-west direction for 3.2
miles, until it intersects Skunk Creek. Here the
boundary diverges from the 10,000 foot contour
line and follows Skunk Creek in a northerly direc-
tion for 2.25 miles. At the intersection of Skunk
Creek and Colorado State Highway 145, the
nonattainment boundary leaves the creek and
follows Highway 145 in a northerly direction until
it meets the service area boundary as it existed
prior to changes adopted in 1991
