Potts series <br />Two existing pits in the vicinity of the Refuse Areas represent the Potts series. Pit 7, the typical <br />location, is located approximately 300 feet south of Refuse Area 9, next of Pond 2/3. The second <br />pit, Pit 8, is located on the eastern edge of Refuse Area SA. <br />Recommendations <br />Satanka series <br />Additional samples should be collect from [Ite vicinity of Refuse Area 7 and Refuse Areas 10 and <br />I I. If the samples appear reasonably similar they will be composited by horizon and sent in for a <br />single se[ of analysis. If their similarity is in question, then ntul[iple samples will be sent in for <br />analysis. The depth at which rock stops penetration in the core holes will determine suitability <br />limitations due to rock. <br />Turley Variant series <br />Sufficient data Itas been collected from this soil series to characterize its reclamation suitability. <br />Potts series <br />This series is represented by ntap unit 108 as a complex with Turley Variant and ntap unit 107. <br />Samples should be collected from Refuse Areas 8/9 and Refuse Areas 10/I 1. If the samples <br />appear reasonably similar they will be composited by horizon and sent in for a single set of <br />analysis. If [heir similarity is in question, then multiple samples will be sent in for analysis. <br />Samples will be collected with afour-foot hand coring tube (1.25"). Individual samples will be <br />based on identifiable horizon and will not exceed one foot of total depth. Samples collected a[ <br />multiple locations within ttte same soil series may be composited by horizon provided they are <br />similar. Analytical parameters will include: <br />pH EC <br />texture SAR <br />%OM fertility (N, P, K) <br />selenium boron <br />Based on Table 1I.1-2 (page 11.1-18) in the pen»it application the limiting factor for these soil series <br />should be bedrock at various depths. <br />if you have any comments on this proposed sampling plan please give me a call at 970-675-4322. <br />Sincerely, <br />~~ <br />Scott Wansted[ <br />Environmental Engineer <br />cc: Jeff Dubbert <br />Murari Shres[ha <br />
