adjusted annually. Grazing levels will be established to permit vegetation management, not to fully utilize grazing capacity. No grazing will be allowed in the mitigation area until the 1991 season (beginning April 15, 1991). Five horses will be allowed in Mitigation Sites A -C during the second year after the start of construction. Another two horses will be allowed in Mitigation Site D. The number of horses shall be adjusted annually according to the standards set above. If grazing adversely affects the mitigation area, it y b relocated erte or reduced pen 24 hours a notice or as soon as the animals can be reasonably Monitoring of Grazing All grazing of pastures in the landfill footprint and grassland in the mitigation area shall be monitored annually during the life of the landfill. The biological cach niton or of he her qualified agent for the County shall evaluate the forage conditions biological monitor shall use the actual use/utilization method to determine the stocking rate for each pasture for the following grazing season. The new stocking rate for each pasture shall be determined b acre RDM foreasuring the each h occurring in the pasture in October. RDM shalhe ggoal l be de ermill ined initially by following the pasture. The number of lbs per/ac "Double Sample Method for Assessing RDM" (U. S. Forest Service 1984). This method consists of clipping and weighing the RDM occurring four orepresentative past qre scan be plot out of five plots per pasture. The remaining Plots estimated visually.

The grams per plot clipped are then converted to lbs/acre by using the following formula: (Grams/454)*(43,560/1 sq ft) = lbs/acre RDM The target RDM for each pasture is 900 lbs per acre. The next seasons stocking rate (AUMs) for each pasture shall be determined by using the following formula: ([RDM remaining - 900 RDM] *acres/ 1,000 lbs per AUM)+current AUMs Pasture A is 42 acres, Pasture B is 33 acres, Pasture C is 19 0 acres, and Mitigation sture D is 19 acres, and Pasture E is 36 acres.
