location, but the velocity is apparently high. This ditch will be <br />• with 3h:ly and 2h:ly side slopes and designed per the attached <br />V�haped LI <br />SECM analysis (Pages 7- 6 -3 -15a to 15d) and riprapped similar to the <br />ditch near the office. <br />Old Boneyird Ditch <br />This ditch was constructed to carry the runoff from the boneyard pond <br />around the boneyard area. This watershed includes the area which flows <br />into the boneyard ditch, the pond and the area adjacent to the ditch. The <br />drainage area for the ditch is approximately 936 acres. This ditch is <br />generally two to three feet deep and five to six feet wide at the top. <br />Runoff from this ditch exits just east of the entrance road to the new <br />boneyard. This water is conveyed off the permit area via the haul road <br />ditch. Please refer to the following SEDCCAD printouts for further <br />information. <br />office Diversion Ditch <br />The office ditch was constructed to intercept the runoff above the office <br />• area and carry it away from the facilities. This area drains <br />approximately three acres. The upper portion of the ditch is <br />approximately two feet deep and four feet wide. Over the years, since the <br />ditch was constructed in 1984, downcutting became a problem on the lower <br />reach of the ditch. This area has recently been regraded and the channel <br />riprapped to prevent this from occurring in the future. This section is <br />approximately 12 feet wide at the top and 2 feet. deep. Please refer to <br />the following SEDCAD printout for additional information. <br />Wadcae Pit Diversion No. IA <br />The Wadge Pit diversion was constructed to carry the runoff from the pit <br />area and discharge it into the drainage above Ponca 008. 'Iris diversion is <br />not a relocation of Diversion No. 1 which may still be constructed. This <br />ditch is actually a combination of a portion of the Wadge Scraper Pit <br />Ditch (10 feet wide and 2 feet deep), the ditch on the northeastern extent <br />of the topsoil removal limits and the ditch at the base of the spoil ( 3 <br />feet deep and 12 feet wide at the top). The lower reach of this ditch was <br />• constructed to intercept the runoff prior to reaching the old diversion <br />7 -6 -3 -9 Revised 12/02/93 <br />
