3 Second Adequacy Review
DMG received Oldcastle's response to our second adequacy review letter for Amendment No. 3 (AM-03) to
Permit No. M-1977-020. The application cannot be approved until the remaining adequacy comments are
addressed. Please submit a complete response to this adequacy review as soon as possible, but no later than
March 10, 2004 so the decision due date set for March 17, 2004 can be met. If your response, or an
extension request, are not received by March 10, 2003 this application may be denied.
In an attempt to make this process more easy to follow, I have separated my adequacy comments into to
categories; those that address the new mining area proposed by AM-03, and those that address revisions to
the existing mining areas and the permit specifications that were put in place during previous permitting
processes such as AM-01, AM-02, and TR-01.
ADEQUACY ISSUES PERTAINING TO THE PROPOSED NEW PERMIT AREA
1. Please provide proof that all landowners (and easement holders)on or within 200 feet of the new
proposed affected area have received a copy of the public notice as required by Rule 1.6.2
(1)(e)(i) and(ii). This would include Wright, Riley, Homefront, Johnson, Laughery, Heinz, DMEA
(elec), Kinder (gasl, Qwest (phonel, and Tri-county (water).
2. Please revise the permit maps to show the correct site name IPit No. 1).
3. The mining plan map will need to be revised to include stockpiles and berms, to scale, illustrating
adequate resource to complete required backfilling tasks. If this resource is not adequate, the
reclamation map should contain a note specifying the amount of material importation required to
complete reclamation.
4. The mine plan map also needs to be revised to include the proposed direction of mining for the
new parcel and show the limits of the .5H:1 V mining operations, and show the active mining
contours for this area.
5. The current stability demonstration addresses the backfilled slopes at final grade of 3H:1 V or
less. To satisfy the requirements of Rule 6.4.19 for all structures within 200 feet of the new
proposed affected area, a damage waiver agreement or an additional engineering stability
demonstration must be submitted for the .5H:1 V (or vertical if appropriate) mine face prior to
advancing closer than 200 feet to any of these structures.
