Mr. Stout <br />East Portal <br />- 2 - February 10, 1988 <br />1) There is a ditch, unnumbered and unillustrated, that runs parallel <br />to D10 and immediately west of the mine entrance road. This will <br />not likely change so it could be added now to the proposed plan and <br />illustrations. <br />2) C7 empties into the unnumbered ditch referenced above. This is not <br />likely to change; so the map could be changed now. <br />3) CB does not empty into D15 as previously noted. Since a choice may <br />be made here by WFC for continuation into D15 by installation of <br />another culvert or use of a different ditch etc., the illustration <br />of this can wait until post-construction wrap up. <br />4) The ditch north of the access road running parallel to D8 should be <br />numbered and illustrated. It could be sized, typed etc. at this <br />time and added to the proposal and illustrations. This will not <br />change. <br />5) D8 has several pieces of drill pipe serving as culverts. These <br />should be replaced by culverts whose size could be determined now. <br />These could be numbered and added to the proposal. <br />6) The work on C10 is underway and a change in location is heing made <br />in the field. Illustration etc, can wait until post-construction <br />wrap up. <br />7) WFC will eventually make a choice of drop inlet for or culverts for <br />D20. This choice can be illustrated etc. in the final wrap up. <br />8) There are 2 unnumbered and unillustrated culverts and a ditch <br />leading into D24 from south of the nearby railroad tracks. The <br />locations, sizes of these will not change. These could be added <br />now to the proposed plan and illustrations. <br />91 A culvert is necessary for D25 to reach the drop inlet as <br />indicated. The inlet is north of a haul road segment D25 must <br />cross. The size of this culvert can be determined now and added to <br />the proposal. This should not change. Could this ditch lead into <br />the ditch etc. under 8) above and not cross the haul road? <br />10) A properly sized, numbered and illustrated culvert is needed in D24 <br />under the ramp down the back side of the clean coal pile. This <br />could be determined now and added to the proposed plan and <br />illustrations. It should not change. <br />(~ ll) D11 could be illustrated now or later to continue past C30 to the <br />outlet of the culvert under Highway 1? where it actually starts. <br />12) The new access road to the RDA will require a ditch. This probably <br />could be sized now, added to the proposal and illustration together <br />with its connections to the system. <br />
