The Division has reviewed New Elk Coal Company's application for a technical revision (TR62).
TR62 provides design information, reclamation detail and reclamation cost estimation for structures
that were subject of NOV -CV- 2011 -008. The Division has the following questions regarding the
information submitted with TR62:
1. Revised Map 12 does not show culverts or ditches. Approved Map 14 in the PAP shows the
currently approved culverts and ditches. The slurry line light -use road crosses Ditch D34B.
How will the road cross the ditch? Will there be a culvert in this location, or will vehicles
drive through Ditch D34B. Map 14 shows culvert C52 west of the proposed slurry line light -
use road crossing ditch D34B. On -site inspection with Bobby Steele of NECC, on January
11, 2012, found that culvert C52 has been removed from Ditch D34B.
NECC could use the same size culvert as C52 for the slurry line crossing of ditch D34B.
However, if a culvert is installed for the crossing, it will be necessary to show it on a Map
14. Please provide an explanation of how vehicles will cross ditch D34B, update applicable
maps if a culvert will be used, and provide appropriate sizing information.
2. On revised page 2.05 -7c, the text describes, "two light use roads and a maintenance road."
The Division does not have a definition of "maintenance road." Please assure that all roads
meet the definition and designs of 4.03. Please revise the appropriate text to eliminate the
name of "maintenance road." Based upon the location and design of the roads, this third road
(zig -zag road) would likely fit the definition of light use road.
