,~ Me/Re:FMC-Revw Soil 8 Veg Bsln Data - 2 - June 12, 1986 1. The EC measurements for Bankard soils are from "Good" to "Fair" (for depths of 0-9", 9"-41" and 41"-60" the respective EC readings are 4.2 mmhos/cm, 3.0 and 2.7). 2. The EC measurements for Youngston soil above 24" are "Good" (for depths 0-5" and 5"-24" the EC measurements are 1.8 mmhos/cm and 2.0, respectively). The Bankard LS soils consist of 90$ Bankard soils versus only 10~ for the Youngston soils. The dilution effect created by the minimal Youngston soil and even more minimal high Youngston EC soil should allow for greater salvaging depth. The "Recommended Depth of Maximum Salvage" for Persayo SiL is 7". However, the specified "Restrictive Feature(s)" is siltstone below 16". Therefore, the salvage depth should be increased to 16" rather than the listed 7". C. The "Recommended Depth of Maximum Salvage" for Torriorthents, fiery shallow and Torriorthents, moderately deep is 10". However, a review of Table 2.04.9-7 indicates a salvage depth of 29" for Torriorthents, moderately deep. The applicant should split this latter soil into a separate category to reflect correct salvage depth. 4. The Division's 1984 PAR requested verification of the depth of "A" and "B" horizon material by sampling a minimum four sites for each soil type for every 25 acres or portion of 25 acres to be disturbed at each facility area. In response, the applicant submitted the Walsh 8 Associates' field notes for the soil samples taken when preparing the November 15, 1983 soil report. The submittal of these field notes does not satisfy the Division's concern about the limited amount of available salvageable soil medium. The applicant must provide the information requested in the original PAR. 5. From the soil inventorying data, the applicant should be able to determine topsoil volume summaries for each of the various soil 'map units of the surface facility area similar to the volume calculations present on Table 3.1-1 for the refuse area. Such calcf~lations will allow the applicant to determine concrete top soiling values for reclaimed areas and to determine if excess material is available far the coal refuse area reclamation. 6. The applicant's July 1, 198 response to the Division's PAR concern pertaining to topsoil replacement as discussed on page 1 of Section 2.05.4(2)(d) raises a-number of concerns.
