Excessive ABP levels were identified in 28.9 percent of the Wo/f Creek overburden at Site 2313E, <br />mostly in the 20 to 35-foot zone above the coo/ seam. Typical overburden handling will effectively <br />bury much of this strata in the central portion of the spoi/ profile. However, based upon previous <br />information from the adjacent Seneca // Mine, acid mine spoi/ may occasionally be identified at the <br />surface of final graded spoi/. These areas, identified by the regraded spoi/ monitoring program, wi/l be <br />buried with a minimum of three feet of suitable spoil prior to soil replacement. " <br />PR04 Sa Revised 04/02 <br />
