Rule 2.04.4—Cultural and Historic Resource Information
4. Cultural and Historic Resource information for the permit area is given on pages 2.04-7
through -10 and in Exhibits 10 and 11 of the currently approved PAP.
Please update the text and Exhibits 10 and 11 with information pertaining to the
permit area expansion proposed with PR -15.
Rule 2.04.11— Fish and Wildlife Resources Information
5. Fish and wildlife resources information for the permit area is given on pages 2.04-162
through -180 and in Exhibits 34 through 38A of the currently approved PAP.
Please review the text of pages 2.04-162 through -180 and associated exhibits, and
update as necessary.
Rule 2.05.3 — Operation Plan
6. Rule 2.05.3(2)(b) requires a detailed narrative, cross section, map(s) and timetable(s)
sufficient to describe the areal extent of the proposed underground workings.
Please update Map 51 E -Seam Projected Operations. The map should present a
coherent mine plan including identifiable panels, shaded to indicate the time at which
they are projected to be mined. The feature "Area of Potential Longwall Panels
Extensions Based on Future Additional Exploration" should be removed from the map.
The features "Approximate Limit of the Maximum Predicted 19° E -Seam Angle of
Draw", "Maximum Projected Areal Extent of Potentially Mineable E -Seam" and
"Projected E -Seam Mining" should be updated.
7. On proposed page 2.05-4, in the fourth paragraph, the final sentence reads "The overall
recovery of the mine layout has not been calculated, because it varies continuously with
changes in mine plans."
Please replace the sentence on page 2.05-4 with a narrative estimate of the coal to be
recovered, including all assumptions, using a range of values if necessary, based on
the mine plan proposed with PR -15.
8. Table 28 — Estimate of Recoverable Coal Reserves at the West Elk Mine, and Table 32 —
Projected Employment Needs at West Elk Mine for the Life of Mine provide important
information about the mine plan.
Please review tables 28 and 32 in the light of responses to items (1) and (2) of this
letter, and update as necessary.
Rule 2.10 — Maps and Plans
9. The majority of maps submitted with the PR -15 application are drawn at a scale of
1":2,000' (or 1:24,000) which is acceptable.
