Ms. Susan Morrison <br />June 2, 1992 <br />Page 4 <br />inspection; however, several rain showers <br />had occurred during the previous week. <br />O. May 27, 1992: The annual embankment <br />inspection was conducted. Skies were <br />cloudy and temperatures in the 60's °F. <br />The mine was wet and muddy at the time of <br />inspection; it had rained that day and <br />numerous rain showers had occurred during <br />the previous week. <br />II. Inspection (05/27/92) <br />A. Crest of Embankment <br />The crest of the embankment is a 60-foot <br />wide roadway used for coal haulage. No <br />signs of stress (cracks) were noted upon <br />inspection of the crest. The roadway and <br />side ditches are well maintained. Safety <br />berms are in place. The side ditches are <br />clean and traverse the entire length of <br />the embankment with no openings for <br />discharge onto embankment slopes. There <br />was some flow in the side ditches on the <br />date of the inspection due to recent <br />thunderstorms. <br />B. Upstream Embankment Slope <br />Vegetation appears somewhat thicker on <br />this slope than the downstream slope and <br />erosion does not appear to be a problem. <br />No cracking was noted on the slope. Only <br />minimal impounding had occurred over the <br />past year as evidenced by the lack of <br />debris or high water lines on the fill <br />slope. The steel stakes set to indicate <br />the 10-year, 24-hour storm water <br />elevation are in place and in good <br />condition. <br />
