Elk Mountains southeast of the Grand Mesa generally above 8,000 feet elevation. The
proposed target area is within an area approximately described as follows: beginning
near the Town ofPaonia at the NE corner ofTI4S R92W 6PM, thence west along the
north boundary ofTI4S to the east boundary ofR98W, thence north along the east
boundary of R98W to the north boundary of TIl S, thence east along the north
boundary of TIl S to the west boundary of R95W, thence north along the west
boundary ofR95W to the north boundary ofT9S, thence east along the north boundary
ofT9S to the east boundary ofR89W, thence south along the east boundary ofR89W
6PM extended into the NMPM to the north boundary ofT49N NMPM, thence west
along the north boundary of T49N NMPM to the east boundary of R7W NMPM,
thence north along the east boundary ofR7W NMPM extended into the 6PM to the
north boundary ofTI4S 6PM and more orless to the point of beginning. (see map in

flare at an average rate of release from any single variable or fixed rate generator not
to exceed seven (7) grams per hour.

16. The permitee shall suspend seeding operations if at any time the average of the snow
pack accumulations, measured in equivalent inches of water, at the snotel sites and
snow-courses selected to represent the target area exceeds a continuous function
defined by the following points:

A. 200% of average on December 1 st,
B. 175% of average on January 1 s"
