Re: Kennedy Sand Mine
Review Comment Response
Brunswick County, NC
NT Project No. 19016
Dear Mr. Parr,
We are responding in red to your review letter dated December 20, 2023, as follows:
1. The permitted area on the affected area table on the mine map only accounts for the
affected area. Please clarify the affected area table on the mine map. The permitted area should
include any proposed undisturbed areas. The table has been updated to include buffers and
undisturbed areas.
2. The permitted area on page 2 of the application is listed as 117.10 acres, however tables
on the mine maps and the table in the application show a proposed area of 39.72 acres. The
tables on plans have been updated. Disregard any tables previously provided in the App.
3. Please provide proof, such as copy of the signed return receipts from certified mail, that
all adjoining landowners and chief administrative officer of each county and municipality have
been properly notified. Copies of return receipts are enclosed.
4. Please provide proof that you have submitted your NOI for your NPDES Permit. A copy
of the NOI cover letter is enclosed.
5. Please provide additional details on the sequence of mining operations. Please clarify if
the temporary sediment basin will only be utilized during the initial establishment of the pit. The
sequencing has been updated. Temporary sediment basins will only be used during initial
clearing phase.

6. The mine boundary is shown as the same boundary as the property line. The mine
excavations and undisturbed buffers around the limits of excavation have been denoted on the
mine map. Please clarify what other activities will occur in the undesignated area between the
permit boundary and the excavation buffers. There is no additional activity planned in upland
areas.
7. Please clarify how the wetlands north of Mine Area #2 will be protected from dewatering
activities. The dewatering basin in Mine area #2 appears to discharge to a drainage area that
will not drain back to the wetlands in the north. The dewatering basin has been relocated so it
will drain back to the wetlands to the north.
8. Please provide a pumping Operations and Maintenance Plan (O&M) for the dewatering
activities. A pumping O&M plan has been provided as requested.
9. Please clearly indicate and label on the mine map the locations of neighboring wells within
500' of the mine excavation. Please provide a well survey and water supply restoration plan.
The well survey should identify any wills within 500 ft of the proposed mine and include well
owner name, address, contact information and well depth. The water restoration plan should
describe action to be taken to investigate water supply complaints, identify cause, and restore
water supply if impacted by mining. An example water supply restoration plan is attached. One
well was found to be within 500' of the proposed excavation limits. The well location has been
noted on the plans. Owner info and well restoration plan have been provided for your use.
10. Due to the potential presence of threatened and endangered species on the site, please
provide either proof of consultation with the US Fish and Wildlife Service or conduct an online
IPaC evaluation to acquire an effect determination. The IPaC site, listed below would direct the
applicant in the appropriate actions. Species that may be in the project area include the federally
endangered northern long-eared bat, proposed endangered tricolored bat, and listing candidate
monarch butterfly. The Client's environmental consultant will provide the required
documentation.
Sincerely,
NORRIS & TUNSTALL
