., <br /> <br /> <br />-3- <br />f) CFBI estimated a mine life of 10 years. WFC should amend this <br />estimate if necessary. This might also change the reclamation <br />timetable presented on Page 2.05-27. <br />g) WFC may wish to reference as built certifications in the <br />appropriate narratives in this section, and organize them into <br />one exhibit. <br />h) The facilities and RDA technical revision should be <br />incorporated into this section, or be referenced as an exhibit <br />in the narrative of this section. <br />i) The minor revision for the non-coal waste disposal area should <br />be incorporated into the narrative on Page 2.05-24. <br />j) The Division is aware that WFC is currently working on a plan <br />to modify the drainage control system at the New Elk Mine. WFC <br />should check the narratives concerning this system to be sure <br />that it reflects what is currently in the field. Any approved <br />revisions concerning the system should be included. For <br />example, the emergency spillway height for Pond 006 in Table 13 <br />should be removed. <br />k) On Page 2.05-28 it is indicated that the sediment ponds may <br />remain as permanent impoundments. However, in your recently <br />submitted reclamation plan pursuant to Stipulation 19, it is <br />stated that embankment material will be used for retopsoiling. <br />WFC should clarify the plans concerning the ponds, and insure <br />that all appropriate performance standards are being met. <br />1) Additional information on backfilling and grading should be <br />supplied, as outlined in my letter of January 17, 1986 <br />concerning Stipulation 16. <br />m) Soils information provided in Exhibit 11 shows that topsoil may <br />be available in the laydown area east of the non-coal waste <br />disposal area. This area is designated A1W on Soils Map 13A. <br />In general, the topsoil plan and material balance needs to be <br />defined in more detail. Also, the soil sample data submitted <br />by WFC indicate possible problems with sandy texture (GE2, <br />NE 6, 7, 9), conductivity (GE2, NE 5, 7), and SAR (GE2). WFC <br />should discuss the test results and possible need for soil <br />amendments. <br />n) Stipulations 19-25 need to be incorporated into the <br />revegetation plan. The recommendations of the CSU revegetation <br />study found in Exhibit 18 should also be included. However, <br />the sentence which indicates that revegetation success will be <br />evaluated by comparison to the CSU study should be deleted. <br />Revegetation success should be evaluated only with respect to <br />the appropriate performance standards of Rule 4.15. <br />
