We have reviewed the modification request your company submitted for the referenced mine site. In order for this
office to complete its review of the referenced project in accordance with G.S. §74-50 and §74-51 of the Mining
Act of 1971, please provide the additional or revised information in accordance with the following comments:
Please clearly indicate and label on the mine map the areas utilized for plant, stockpiles, process areas,
roads, boneyards, and quarry office and scales on the mine map. The current line weight and color are
only indicated by label and leader line and are also similar in color and line weight to other use areas.
Please consider changing the line weight, color, or dashing and adding a legend so that these areas are
more easily distinguished on the mine map.
2. Please clearly indicate and label on the mine map the required diversion ditches for Erosion and
Sediment Control (E&SC) measures. Please provide calculations for these diversion ditches.
3. Please provide construction drawings and maintenance details for all E&SC measures including but not
limited to silt fence, construction entrance, stilling basins, energy dissipators, etc.
4. Please provide construction details and cross sections for proposed screening berms. Please clearly
indicate and label on the mine map the location of new screening berms.
Affected land includes nonpublic roads. Please clarify how the access road going to the west will be
permanently barricaded to prevent access from the area that is proposed to be removed from the mine
permit boundary.
Please note, this office may request additional information, not included in this letter, as the mining application
review progresses. Be advised that our review cannot be completed until all of the items listed above have been
fully addressed.
