<br />1.0 INTRODUCTION <br />1.1 Purpose ~ Scope <br />A soil inventory of the pit, overburden stockpile, and surface <br />facilities areas of the Carbon Junction Mine was conducted by James <br />P. Walsh ~ Associates Inc. to assist Pueblo Coal Company in <br />environmental permitting and reclamation planning. The inventory was <br />conducted to meet the Rules and Regulations of the Colorado Mined <br />Land Reclamation Board Pursuant to the Colorado Surface Coal Mining <br />Reclamation Act, 34-33-101 et seq. The soil inventory addresses <br />section 2.04.9 Soils Resources Information. <br />A program of description and sampling was conducted to respond to <br />questions of the Colorado MLRB. The inventory is based on the <br />original mapping of the SCS and field refinements conducted by Walsh <br />and Associates, Inc. during January 1983. <br />1.2 Methods <br />The soil mapping is a refinement of the SCS mapping based on land <br />form interpretation, eight backhoe pits, about a dozen hand dug <br />holes, and surface observations. Mapping was difficult due to heavy <br />snow cover but the SCS mapping, backhoe pits, and the other obser- <br />vations provide sufficent intensity of data points for adequate <br />accuracy of the mapping in areas to be affected. The scale of field <br />mapping was 1 inch equals 500 feet (1:6000). <br />Each major soil series or taxadjunct (except the Zyme) in the permit <br />area was described in detail. Descriptions include: <br />o series name <br />o sampled pedon number <br />o map unit(s) in which it is a major component <br />o depth <br />o drainage class <br />o slopes <br />o landform and parent material <br />o representative profile (surface, subsoil, substratum) <br />o native vegetation <br />o permeability <br />o available water holding capacity <br />o effective rooting depth <br />SCS map units refined in the field, are site specific, and designed <br />for the purposes of this study. For each map unit the following are <br />described: <br />• o symbol <br />o name <br />o major components and their percentages <br />o minor inclusions and their percentages <br />4 <br />
