Mr. James Dillie Adequacy Letter, Apache Mine Permit No. M78-009 Page ] 2 Other Issues: In an April 1999 letter, the El Paso County Soil Conservation District expressed the following concerns. The El Paso County SCD has reviewed your amendment to the Apache permit and have the following comments: 1. There is a large terrace in the upper part of section 20. /f sediment frlls it will not operate effectively. The terrace is protecting a headcut that enters Brackett Creek. 2. There is a series of ponds and wetlands on the sau[hern edge of section 20. This area will need proper protection. 3. Haw much land will be open at any one time? We s[rongly recommend concurrent reclamation to minimize t/re amount of land that might become eroded by either wind or water. 4. What would be the recommended seeding rate and species that you will use to reclaim the pit once mining is completed? S. Do you have a noxious weed contra/ plan in place? ROBCo has reviewed the questions and is confident the permit addresses the EI Paso County Soil Conservation District's (SCD) concerns. SCD Items 1, 2, and 3 aze addressed in multiple azeas of the permit, but the most prominent commitment to these items is "A total disturbed azea at any one time will not exceed 39 85 acres. Of that 3@ 85 acres, no more than ~5 40 acres will need partial backfilling and recoiling; any disturbed acreage on the remaining d-3 45 acres will have been backfilled and recoiled and in the final stages of reclamation. Of the 45 acres, 20 acres will have been seeded, leaving 25 acres for seed and fertilizer." The secondary commitment to these items is the stormwater management plan outlined in the Division's Item 6 above. SCD Item 4 is addressed in the specific seed mixtures and rates discussed in the Division's Item 7 above. And, SCD Item 5 is addressed with the following addition to Page 16 of Exhibit E in response to the Inspection Report prepared by James Dillie at the Division upon completion of the October 26, 1999 Division Inspection. During the early spring, on an annual basis, Robinson Brick Company will inspect the Apache Mine permit area to determine if new or additional weed control measures are required. If a tweed noxious weed problem continues, ROBCo will take whatever reasonable steps are necessary to eliminate these problems. If, for whatever reason, ROBCo is not able and/or successful in controlling the kxw noxious weed problem at the Apache mine, ROBCo will contact the Division for further assistance.
