Ms. Susan Burgmaier <br />August 31, 1995 <br />Page 3 <br />however, several rain showers had occurred during the <br />previous week. <br />O. May 27, 1992: The annual embankment inspection was <br />conducted. Skies were cloudy and temperatures in the <br />60's° F. The mine was wet and muddy at the time of <br />inspection; it had rained that day and numerous rain <br />showers had occurred during the previous week. <br />P. June 10, 1993: The annual embankment inspection was <br />conducted. Skies were clear and the temperature was in <br />the 70's° F. Prior to today, afternoon showers had become <br />commonplace for several days. The mine was relatively <br />dry. <br />Q. June 8, 1994: The annual embankment inspection was <br />conducted. Skies were clear and the temperature was in <br />the low 70's° F. Recent dry weather had dried out most of <br />the mine site ephemeral drainages, including this one. <br />R. June 28, 1995: The annual embankment inspection was <br />conducted. Skies were partly cloudy and the temperature <br />was in the 70's° F. The mine was relatively dry at the <br />time of inspection, and no rain had fallen in over 10 <br />days. <br />II. Inspection (06/28/95) <br />A. Crest of Embankment <br />The crest of the embankment is a 60-foot wide roadway <br />used for coal haulage. No signs of stress (cracks) were <br />noticed during the inspection of the crest. The roadway <br />and side ditches are well maintained. Safety berms are in <br />place. The side ditches are clean and traverse the entire <br />length of the embankment with no openings for discharge <br />onto embankment slopes. <br />B. Upstream Embankment Slope <br />Vegetation again appears to have a higher cover on this <br />slope than the downstream slope and erosion does not <br />appear to be a problem. No cracking was noted on the <br />slope. Only minimal impounding had occurred over the past <br />year as evidenced by the lack of debris or high water <br />lines on the fill slope. The steel stakes set to indicate <br />the 10-year, 24-hour storm water elevation are in place <br />and in good condition. <br />
