Memo -Jim Stevens - 2 - April 19, 1989 area. In conjunction with this two samples from each pit (one from the A horizon and one from the B horizon) should be collected and analyzed for the following parameters to determine the soils suitability for reclamation (pH, % OM, EC, SAR, Saturation %, Particle Size Analysis, Texture, N, P, K). Upon receiving this information a determination can be made about the quantity and quality of soil available for reclamation purposes. (2.04.12) Prime Farmland Investigation The second area of concern is the prime farmland investigation. The operator requests that a negative determination be made with regard to prime farmland in the area. It is unlikely that prime farmland exists within the proposed permit area; however, I think it is in the best interest of the Division to further document this. Therefore, I recommend that the operator obtain a letter of concurrence from the local SCS office stating that prime farmland does not exist in the permit area and will not he affected by the proposed operation. 2.05.3(5) Topsoil Removal and Storage There are a couple of points which will require clarification in this section. The first one is the proposed stripping depth which is not expected to exceed one foot. Based on the soil description provided there may be as much as two (2) feet of useable topsoil available. Therefore, my preliminary recommendation is that a minimum of one foot be stripped and fifteen (15) inches should be the average s ripping depth. A final determination of stripping depth will not be possible until the soil resources are mapped in more detail on the proposed disturbance area. I am basing my preliminary recommendation on achieving a final cover of at least 12 inches which should be sufficient to meet the final land use of rangeland. Taking into account variables for rock content, settling, compaction, erosion, operator error, etc., I feel that a final cover of twelve (12) inches can be achieved by stripping, stockpiling, and replacing fifteen (15) inches of topsoil. This is a preliminary recommendation and if after further investigation of the soil resources it is determined that a considerable area is composed of the Capulin soil I would possibly recommend a deeper stripping depth. The second point I would like to address in this section is that of the proposed cover crop for protection of the topsoil stockpiles. The application contains a statement which says, "These plants shall be determined in cooperation with the local Soil Conservation Service". This statement is inadequate and should be deleted from the text or have, "and be approved by the Division", on the end of the sentence. The operator may obtain recommendations from the local SCS; however, he should submit a temporary seed mix in a format analogous to the final revegetation seed mix. Upon receiving this mix it will need to be approved by the Division.
