Each plant community type with physical <br />disturbances greater than three percent of the total disturbances <br />must be sampled. You stated that the Snowmass Mine and Loadout <br />would be one permit and hence disturbances for each could be com- <br />bined. You further stated that there are 35 acres of disturbance <br />at the mine and our vegetation study (Plant Community Evaluation, <br />Snowmass Coal Loadout Facility, June 19801 determined that 20 acres <br />would be affected by the loadout project. Thus, there is a total <br />of 55 acres disturbed and any plant community with 1.65 acres <br />disturbed 155 x .031 must be sampled. <br />These criteria delineate four plant community types for sampling. <br />They include: <br />- Riparian in valley bottom <br />- Mountain shrub on south-facing shaly slopes <br />- Aspen and conifer on north-facing slopes along access road <br />to air fan <br />There is a second shrub comm uniTy along this access road but dis- <br />turbances are well below 1.64 acres. It is our understanding that <br />sampling will not be required. <br />
