RULE 2 PERMITS <br /> <br />South Taylor – Rule 2, Page 28 Revision Date: 7/21/25 <br /> Revision No.: MR-267 <br />only. Soils information for all other current Colowyo areas is contained in the existing Colowyo permit <br />documents. <br /> <br />Order III Soil Survey – Permit Revision Area <br /> <br />The general soils resource information used to describe the distribution, properties, and present and <br />potential productivity of soils within the South Taylor permit revision area are included in the following: <br /> <br />• Unpublished Natural Resources Conservation Service (NRCS) Order-III soil survey maps and <br />map unit descriptions for Moffat County, Colorado (NRCS, Craig, Colorado); <br />• NRCS - Soil Survey Division soil series descriptions (http://www.statlab.iastausete.edu/cgi- <br />bin/osd/osdname.cgi). This information was used for portions of the permit revision area located <br />in Moffat County, Colorado; and, <br />• Order-III soil survey maps and map unit descriptions found in the Soil Survey of the Rio Blanco <br />County Area, Colorado (1982). This information was used for those portions of the permit <br />revision area located in Rio Blanco County. <br /> <br />NRCS soils map information within the South Taylor permit revision area was reviewed and is presented <br />on Map 5A, Order III Soils. NRCS soil map units were identified in the area and are provided in Exhibit <br />9, Item 5. The information provides antiquated series names and updated NRCS field map symbol <br />identifications. Present and potential productivity of the soil units are provided in Table 2.04.9-4. <br /> <br />Generally, the map unit boundaries from the unpublished NRCS soils maps for Moffat County match <br />with those for the Rio Blanco County soils maps. To the west of the existing permit area, the mapping <br />unit boundaries from the two soil surveys match at the county line. However, the soil map unit names are <br />different for each county. These differences are the result of changes in the NRCS soil classification <br />system from 1982 (when the Rio Blanco survey was published) to 1998 when the Moffat County maps <br />were made available to the public. <br /> <br />Order II Soil Survey – South Taylor Mining Area <br /> <br />This section presents data assembled, collected, and analyzed specifically for the South Taylor mining <br />area. <br /> <br />General Soils Resource Information – The identification and proper management of soil resources in <br />the mining area is essential for the success of reclamation of any future disturbed areas and the <br />achievement of the post-mining land use. The objective of this section is to meet the requirements of <br />Rule 2.04.9 et seq. by furnishing soils information for the mining area in sufficient detail to determine the <br />following: <br /> <br />1) General distribution, properties and present and potential productivity of soils within the South <br />Taylor/Lower Wilson affected areas; <br /> <br />2) Distribution, suitability, and average salvage depths of soils within the disturbed area associated <br />with the South Taylor mining area; and, <br />3) Quantity of salvageable suitable soil material for use in the reclamation of the disturbed area <br />associated with the South Taylor mining area. <br /> <br />Detailed Soils Resource Information – The site-specific soils resource information described below <br />pertains to the disturbed area associated with the South Taylor mining area shown on Map 5B.
