Thank you for the time you and Tiffany Hawkins spent for the pre-operation inspection of this site last week. The
report of that inspection will be mailed to you under separate cover. There were numerous other issues we discussed
during the inspection, many of which are technical adequacy issues and are repeated in the following paragraphs.
Please provide responses to each item below, and identify it according to the exhibit to which it pertains. Portions of
the application and its exhibits that are considered adequate at this time do not appear in this letter.
Exhibit A - Legal Description (Rule 6.4. 1)
Map Al and the text provided in this exhibit depict only one entrance and no means of accessing Phase III. Please
revise the exhibit materials to include description and depiction of all entrances and onsite access road locations. (This
adequacy item is repeated for the other map exhibits, below.) Please note that any additional site entrances and/or
onsite access roads that are to be used for this operation, which are pre-existing and will not be significantly improved,
are not required to be added to the proposed permitted acreage.
Exhibit C - Pre-mining and Mining Plan Maps (Rule 6.4.3)
Map C.3 includes fencelines along the perimeter of the quarter section in which the proposed 89.38-acre permit area is
located, and Sixmile Road adjacent to the south side of the site. These are considered significant structures. Item "g"
states that there are no structures within 200 feet of the permitted area. Please revise the text, and ensure that these,
and any other such structures, are adequately described in Exhibit S.
Map C.3 shows a flowing well and a nearby ephemeral pond area. Though both of these features are clearly outside of
the permitted area, please revise the text (item "f") to include information about the well and pond, sufficient to
explain how there will be no adverse impact to these features.
Map C.3 shows the boundaries of the three mining phases, but no additional information about the mining plan, though
it is required. Please provide a revised map that includes the entrances, onsite roads, arrows showing the direction of
mining in each phase, areas that will be mined and not mined, and stockpiling and/or processing areas, as appropriate.
(Note: A sequence of maps, such as the three Reclamation Maps that were provided in Exhibit F, may be considered as
a way to show the sequence of mining phases.)
Please ensure that all contour lines are labeled with their elevations, and that each revised map is signed and dated.
