occurs in the incised drainage areas. The disturbed riparian type occurs along Sage Creek in <br />the east end of the haul road corridor. • <br />Methodology <br />Tasks performed to accomplish project objectives included: <br />• Review of existing soil information <br />• Detailed field mapping of soils in (Order 11 and outside (Order 21 the disturbance area, <br />but within the permit area <br />• Reconnaissance mapping of soils (Order 31 located outside of the permit area, but <br />within the Pond 009 watershed <br />• Soil sampling and profilr. description of all dominant soils within the projected <br />disturbance area <br />• Evaluation of soils for reclamation potential <br />• Interpretation of soil properties to determine hydrologic characteristics <br />The methodology used during the soil survey followed standard techniques and procedures of <br />the National Cooperative Soil Survey as outlined in SCS (19751, SCS (19801, SCS (198'11, SCS <br />(19821, Fosberg and Falen (19831, USDA-SCS 119711, and Soil Survey Stafi 119961. <br />The design of the survey was based on DMG rules 2.04.9, 2.04.12, and 2.06.6, statute 134- <br />3 3-1 1 01211q) CSCMRAI, and consultation, as well as SCC soil survey specifications. The initial <br />soil survey program (1979) was reviewed for completeness and technical adequacy on .lanuary <br />14 and 17, 1983 by Mr. Jim Herren, DMG reclamation specialist and lead person IdurinEi 1982- <br />19841 responsible for review of the soil survey baseline study. Mr. Herron's concerns were <br />addressed by selecting 51 topsoil depth verification sample sites within the Seneca II-W <br />disturbance area during the 1983 and 1984 surveys to evaluate and confirm or revise the <br />topsoil resource information previously collected in 1979. Soil survey techniques used to <br />expand the study area along the tie-across haul road corridor in May 1985 were revie~.ved on <br />April 12, 1985 by Mike Long and IJlike Savage, DMG reclamation specialists. Similar procedures <br />were used again in April/May 1989 along the tie-across haul road corridor. Soil survey <br />procedures for the 1990 mine expansion area were identical to those approved on July 25, <br />1989 by Carl Mount, DMG reclamation specialist, for Peabody's 1989 baseline soil survey for <br />the Yoast area. <br />• <br />6 Revised 9/98 ~~ <br />
