The basis and calculation of the allowable first hit herbaceous cover is <br />presented beginning on page 10 of the revegetation success evaluation report by ESCO <br />Associates in Attachment E — Revegetation Supporting Documentation. <br />Table 1. Vegetation Cover Sampling Summary, Phase II Bond Release Block and <br />Reference Area (RA), Seneca II Mine. <br />' Mean for purposes of sample adequacy calculation; uppermost possible value of the mean, <br />15.1 taken forward for use in performance standard calculation; see text. <br />Sample adequacy using first hit cover was met for the Phase II bond release block and the two <br />reference areas. When sample adequacy was calculated using allowable first hit cover, it was met <br />for the Phase II bond release blocks and the sagebrush reference but not the mountain brush <br />reference area. The sampling results and statistics for total first hit cover and allowable first hit <br />herbaceous cover are summarized below in Tables 2 and 3. <br />7 <br />
