I have reviewed the referenced revision application, including amended text, tables, and
appendices of Section 2.04.9 (Soils Resource Information) and Section 2.05.4(2)(d)
(Topsoil Redistribution). I also reviewed the amended maps 2.04.9-1 (Soil Baseline
Map) and 2.05.4-4 (Postmining Topsoil Replacement), and the new Map 2.04.9-2
(Topsoil Balance Map as of February 2008). My comments are itemized below. Please
let me know if you have any questions.
Section 2.04.9 (Soil Resource Information text tables appendices and maps)
1. The two maps included in the Section 2.04.9 submittal are not listed in the Table
of Contents. Please revise the Table of Contents to list Maps 2.04.9-1 and
2.04.9-2.
2. In Table 2.04.9-1 (Procedures and Analytical Procedures Utilized for [Premine]
Topsoil Analysis), on page 2.04.9-11, it is indicated that physical characteristics
of each sampled profile were described and recorded. This information does not
seem to have been included in the Section 2.04.9 tables or attachments, and needs
to be provided to supplement the soil laboratory data. Please provide this
information for inclusion in the application if available.
3. Soil analytical data from the 1998 study is included in Appendix 2.04.9-7,
referenced in narrative page 2.04.9-12. On Attachment page 2.04.9-7-11 the
columns are shifted or misaligned, such that some of the parameter listings do not
fall under the appropriate column heading, making the data on that page difficult
