RE: Dunbar Mine
Edgecombe County
Tar-Pamlico River Basin
Dear Mr. Pipken:
We have reviewed the application your company submitted for the referenced mine site. In order for this office to
complete its review of the referenced project in accordance with N.C.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:
1. Please fill out the acreage table found on Page 4 of the permit application.As this is a new permit,only
the column labeled"Total Affected Acreage"will need to be completed.
2. Please add the applicant's name to all mine maps, "Carolina Aggregate Sand Holdings LLC."
3. Identify all hydrogeologic features(wetlands,watercourses,waterbodies, etc.) on the map
4. Provide a plan detail, construction specs, and specific maintenance requirements for all proposed
erosion& sediment control measures included on the plan.
5. Please provide construction drawings and maintenance requirements for all E&SC measures including
but not limited to silt fence, construction entrance, stilling basins, energy dissipators, etc. These
measures should also be shown on the mine map with lines/hatching/symbols and an updated legend
as needed.
6. Show the location of all culverts/pipes for the access road on the mine maps.
7. The stockpile, fuel storage and processing equipment are located directly in front of the silt pond and
would restrict the flow of water into it. How will water flow through this area into the basin/pond?
Sheet flow into basins is discouraged. Discharge water into the basin in a manner to prevent erosion
(diversions, berms, etc.). Provide a stable conveyance from diversions into basins (i.e. rip rap lined
channel, slope drain,tarp, etc.).
8. Please provide design calculations for the silt pondibasin and diversion ditches.

9. Detail notes (cross-section) on maps C-02 and C-03 show a haul road inside an undisturbed buffer.
Undisturbed buffers may not have any land disturbing activity at all within them.Unexcavated buffers
may be disturbed for E&SC measures, berms and haul roads, etc., but may not be excavated. Please
revise the detail and include any permanent haul roads on the mine maps.
10. There are two areas on the mine maps, the south-western corner and the eastern most corner on the
north side of the proposed permitted area,where the"Center of 6' Berm"line runs through the line for
the"Excavation Area"indicating the berm running inside the excavation area.Please revise these lines
so the berm is not in the excavation area.
11. Please refer to Section D of the mine permit application and provide a reclamation map that clearly
illustrates the reclamation plan for the entire site. The map should clearly illustrate the post mining use
of the entire site. It should also include all italicized items listed in the application.
12. To determine whether the operation will have unduly adverse effects on potable groundwater supplies,
wildlife,or fresh water,estuarine,or marine fisheries,please provide a surface water delineation of the
proposed permit area.Streams on and adjacent to the property may be subject to the Tar-Pamlico Buffer
Rules.Impacts to surface waters that are above the General Certification threshold would require a 401
Water Quality Certification.
13. The application has not been signed by an officer of the company. Matthew Pipkin is not listed as an
officer or managing member of Carolina Aggregate Sand Holdings LLC in the public filings on the
Secretary of State Website.An officer of the company will need to sign page 1 and the land entry
agreement on page 19 of the application or provide proof that Matthew Pipkin has signature authority
for Carolina Aggregate Sand Holdings LLC.
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.
