The cradle system provides flexibility in maintenance <br />since the cradles can easily be cleaned and fresh hay substituted for <br />the soiled hay. The straw dikes are working very well and have approx- <br />imately a 2" head loss across them. <br />The Rockcastle Company has cleaned the entrances and exits to its culvert <br />system. In some cases the culverts have been extended to prevent collapse <br />of the exit. A plan has been implemented to riprap the exits of all cul- <br />verts. Closer attention is being given to the encroachment of the haul <br />road on Grassy Creek. That portion of Grassy Creek which had been partially <br />blocked has been cleared and the creek is now flowing smoothly. <br />We have laid plans for additional erosion control and topsoil handling. The <br />mine is close to reaching a stable operating mode and topsoil will immedi- <br />ately be spread on reclaimed areas as outlined in the original permit appli- <br />cation. The diversion ditch system will be upgraded and runoff from the <br />storage pile outside the diversion ditch at pit B will be accomodated by <br />a small depression built to capture runoff from that stockpile only. Addi- <br />tionally, topsoil stockpiles and dressed downslopes along the haul road <br />which have topsoil spread on them will immediately be seeded with an appro- <br />priate spring seed to establish some vegetative cover. In the fall, the seed <br />mixture approved by the permit will be planted on schedule. <br />As you know, the mining operation lags the mining sequence outlined in the <br />permit. This lag is a result of unforeseen market fluctuations and weather <br />conditions. In order to correct the sequence for your files and to show <br />minor changes in the road layout and pit locations, we will submit an updated <br />map and textual explanation of the changes in the very near future. We hope <br />to submit this information in time for the Board to approve the changes via <br />a technical revision at the May Board meeting. <br />If I can answer any questions on the work that has been performed to date or <br />on future plans for the mine, please feel free to call. <br />Very truly yours, <br />-~.-~ ,~- ,P~ <br />Tommy D.
