RE: Lake Rhodhiss Hydraulic Sand Mining Operation—Burke County, NC
DWQ/Surface Water Protection Section
To Whom It May Concern, _ Asheville Regional office
The County of Burke desires and seeks to conduct hydraulic sand mining in a section of Lake Rhodhiss,
part of the Catawba River-Duke Energy Hydroelectric Project.This letter is to seek agency comments.
Enclosed is a package of several maps outlining a proposed development inside the FERC project
boundaries. As part of the Duke Energy Lake Rhodhiss Project, Duke and FERC requires that developers
of smaller industrial projects, such as hydraulic sand mining, to consult with federal and state resource
agencies regarding their proposed development.
Carolina Sand Inc., has contracted with Burke County to conduct Hydraulic sand mining on the
properties detailed in the attached maps. Carolina Sand Inc. is a leader in the industry with numerous
sand dredging sites located throughout North Carolina.
Sand mining is necessary because of the influx of sand material from the Catawba River that is directly
related to the impounded waters of Lake Rhodhiss. Further the dredging will increase channel capacity
and sediment buildup.This portion of the lake is often unnavigable via boat.
The sand mining operation will consist of approximately 31.53 acres of in stream dredging area. In
addition, the site will meet or exceed federal/state mining safety regulations (MSHA). More specifically,
the processing and stockpile area will receive sand material from the hydraulic dredge located in the
Lake Project Boundaries from 12-18" HDPE pipelines. Once received at this area it will be screened and
sorted for removal and distribution offsite. The excess water will be treated through a series of
permitted measures to remove sediment and eliminate turbidity and then returned to the lake. This
process will be approved via a NPDES Stormwater Discharge permit from NCDENR. A safety plan will be
developed.
The sand will be mined using a hydraulic dredge/barge operation. This dredge will pump sand to the
processing area. The site will adhere to all pertinent environmental laws, including, but not limited to a
NC mining permit, a NCDWQ stormwater Permit, USACE wetlands and stream permits (if Applicable).
The property will be accessed via the existing and established access located at the Burke county
Landfill.This access has been in place since the existence of the Landfill Operation.
Although we have described the operation in its entirety,the only portion of the operation that is
proposed to occur on project property will be the hydraulic dredge a small portion of pipe line, and the
dredge access area. Please provide to me any written comments on this proposal within thirty(30)
days. Agency comments will be forwarded to Duke and FREC as part of our application for approval of
the proposed development. Duke Energy will consider agency comments in evaluating and approving
the proposal.
Thank you for your review,

North Carolina Wildlife Resources Commission
Gordon Myers,Executive Director
MEMORANDUM
TO: Brenda M. Harris,Mining Program Secretary
NCDENR, Division of Land Resources, Land Quality Section
FROM: Andrea Leslie, Mountain Region Coordinator
Habitat Conservation Program
DATE: January 16, 2015
SUBJECT: Mining Permit Application for Carolina Sand Inc.
Burke Landfill Sand Pit, Burke County
Biologists with the North Carolina Wildlife Resources Commission(NCWRC)reviewed the
application for a mining permit for the Burke Landfill Sand Pit in Burke County. Our comments
on this permit action are offered for your consideration under provisions of the Mining Act of
1971 (as amended, 1982; G.S. 74-46 through 74-68; 15 NCAC 5) and the North Carolina
General Statutes (G.S. 113-131 et. seq.)..
The mining site is located on the Catawba River at the upper end of Lake Rhodhiss,between the
Johns River and Lower Creek. The area to be mined by hydraulic dredging is within a"permit
boundary"that lies in the river channel. This area is 32 acres, on approximately 5,900 ft of
channel. Outside of the permit boundary, a 25-foot undisturbed in-stream buffer is proposed. On
the north side of the permit boundary, a 50-foot undisturbed buffer is proposed in addition to the
in-stream buffer. The dredge pipeline crosses the shoreline near the upstream end of the project
boundary.
This area supports a warmwater fishery. Our review did not indicate threatened, endangered or
significantly rare species at this location. NCWRC often objects to instream mining activities as
they disrupt and impair both aquatic and terrestrial habitats. In this instance, mining operations
are expected to reduce sedimentation impacts to Lake Rhodhiss which is experiencing a
reduction in deepwater habitat and water storage capacity.
The applicant proposes to dewater the sediments in settling basins, "where clean water will
eventually travel back into the river basin via drainage." The outflow from the settling basins

Telephone: [phone] • Fax: [phone]

Carolina Sand Inc. Page 2 January 16,2015
Burke Landfill Sand Pit
will flow onto a short riprap apron and be allowed to run back into the river through the buffer.
We are concerned whether diffuse flow can be maintained through the buffer; depending on the
outflow structure design and topography of the site, the outflow may erode a gully and be the
source of sediment to the river.
Should the permit be renewed, we offer the following recommendations to minimize impacts to
aquatic and terrestrial wildlife resources:
1. Settling basin and outlet design should incorporate measures to ensure that outflows will not
cause land erosion and resulting sediment inputs to the river.
2. The river channel should not be widened or constricted.
3. The permit boundary at the upstream end of the project should be moved approximately 400
feet downstream so that it does not adjoin the NCWRC Johns River Game Land.
4. Stream banks associated with the mining activity should be protected from disturbance and
stabilized with native woody vegetation.
5. Except for the access point and boat access lane, stream banks and riparian buffer zones
should be preserved in, or restored to, natural forested conditions.
6. Measures must be taken to protect the safety of boaters traveling upstream and downstream
through this portion of river. Signs should be placed on the banks upstream and downstream
of the project to warn boaters of the dredging operations. Dredging operations should occur
only during daylight hours. When boats are moving through the project area,the dredge
should stop operating and move toward the bank, allowing boats to pass. When not
operating,the dredge and pipelines should be moved toward the bank to avoid impeding boat
traffic. Any equipment that is left in the river should be marked with reflective floating
buoys to ensure that it does not pose a hazard to navigation.
7. A Duke SMP permit should run concurrently with the DENR mining permit. If the applicant
proposes to renew the DENR mining permit,the applicant must also go through the review
process for the Duke SMP permit.
8. Any woody debris (slash or large trees)removed during site development should be placed
along the outer stockpile/compost area construction limits in the form of brush piles and
downed logs to provide cover and nesting habitat for wildlife.
9. The reclamation plan includes Fescue. NCWRC discourages the use of this highly invasive
plant and instead encourages the use of more wildlife friendly species, such as Creeping Red
Fescue,Switchgrass, Big Bluestem, and Black-eyed Susan. Consider using seed mixtures
that are beneficial to wildlife (e.g., native warm season grasses) in the reclamation plan. An
exact seeding mixture would need to take into account soil types, moisture,pH, and degree of
slope of areas to be stabilized. We refer the applicant to Danny Ray,District Wildlife
Biologist at(828) 391-1161 for additional information and ideas on reclamation for wildlife.
Thank you for the opportunity to review and comment on this permit action. Please contact me at
[phone] if you have any questions about these comments.

Wilksboro,NC 28697
Subject: Carolina Sand Inc. Hydraulic Sand Mining Operation Burke County
Dear Ms. Wilks and Mr. Goddard:
On February 7,2017,the Division of Water Resources (Division) received your correspondence
for the subject project. You are seeking written comments regarding the proposed project and
the Division's interests in the protection of water quality.
Carolina Sand, Inc. seeks to conduct year-round hydraulic sand mining in Lake Rhodhiss. The
proposed sand mining operation will involve approximately 18.7 acres of in-stream dredging
area using a hydraulic dredge/barge operation. Sand material from the dredge will be delivered
to the processing and stockpile area through 12 to 18 inch HDPE pipelines. Excess water will be
treated to remove sediment and eliminate turbidity and then be returned to the lake.
Because the project does not involve a discharge of fill material,=a 401 Water Quality
Certification is not required. The Division renewed the Certificate of Coverage NCG520105 to
discharge under General Permit NCG520000 on June 2, 2016. The project boundary for the
proposed dredging area(Sheet C 100) is not what was permitted under the General Permit
NCG520000. Any modification to the existing General Permit will require approval from the
Division.
The proposed project must comply with the Catawba Buffer Rules(15A NCAC 02B .0243(b).
In addition,the dredging operation discharge shall not cause an instantaneous turbidity
measurement greater than 25 NTUs in the receiving lake. If the turbidity exceeds these levels
because of background conditions,the discharge cannot cause any increase in the turbidity of the
receiving water.
Contact Kevin Mitchell at 828-296-4650 or kevin.mitchellkncdenr.gov if you have questions or
concerns.

Flow Semiannual Estimate Effluent
Turbidi
1. Effluent is defined as "runoff from sand dredging operations and/or discharge fiom the retention
pond(s).
2, The permittee shall make every effort to estimate the semi-annual flow requirement during times of
operation(if operational during the calendar year).
3. The discharge shall not cause an instantaneous measurement of the turbidity of the receiving water to
exceed:
• 10 NTU streams,lakes and reservoirs designated as trout waters
25 NTU all lakes,reservoirs and all salt waters
9' 50 NTU all other streams and surface waters
.If the turbidity exceeds these levels because of background conditions,the discharge cannot cause any increase
in the turbidity of the receiving water.
Submittal of monthly Discharge Monitoring Reports(DMRs)shall not be required except upon demand by the _-
Division. This section supersedes the requirement for submitting-monthly Discharge Monitoring Reports
(DMRs) specified in Part,Section D(2)of this permit. Even though the submittal of the monthly monitoring
reports to the Division is suspended, all monitoring-requirements remain, The data will be maintained on site
for a period of three years.
The applicant will be required to monitor regularly for flow and those parameters limited in Section 2
above with sufficient frequency to ensure compliance with the permit conditions. Frequency, methods
of sampling, and report dates will be specified in the final permit.
SancfDredgina discharges to PirimW Nursery Areas(PNA)waters of the State are prohibited r
Sticks,leaves and other debris removed on shore shall not be returned to surface waters.
The per mittee shall operate the facility and use sound management practices to ensure that impacts to the
surface waters are minimized.
Page 2 of 17

General Permit NCG520000
The permittee shall operate the facility and use best management practices to ensure that stream banks are
stabilized, and dredging equipment must be maintained in a manner to prevent petroleum leaks and spills.
The permittee shall install warning signs, one on each side of the river, a short distance upstream of the
sand dredging operation to wain canoeists and other recreational water users of the operation. The signs
should include the following wording in 2 to 3 inch high white letters on a red background:
CAUTION: SAND MINING OPERATION AHEAD
CRANES,FLOATS AND/OR SUBMERGED CABLES ACROSS RIVER.
BEACHING ON OR ACCESS TO SAND DREDGING SITE IS PROHIBITED,
Visibility of the signs should be maintained as necessary. In addition, the permittee may wish to post a
"No Trespassing" sign on their equipment so_that it is visible when they are not operating, such as on
weekends and evenings after 5:00 pm.
There shall be no discharge of floating solids or visible foam in other than trace amounts.
PART I
SECTION &SCHEDULE OF COMPLIANCE
I. The permittee shall comply with Final Effluent Limitations by the effective date of the Certificate of
Coverage.
2. Permittee shall at all times provide the operation and maintenance necessary to operate the existing
facilities in accordance with Part H.C.2 of this permit. .
SECTION C. APPLICABLITY
This permit is applicable to the following types of discharges:
i. Wastewater from in-stream sand mining operations using dredging, dragline or similar equipment.
- This wastewater is typically from sand piles deposited on the bank or from settling ponds.
2. Stormwater associated with the in-stream sand mining operations. This stormwater is typically
runoff from sand piles or stormwater,which accumulates in the settling ponds. Stormwater outfalls
that do not naturally drain to settling ponds or other mining operations should not be diverted to
comingle with wastewater. If the stormwater outfalls are separate and distinct from the mining
operations;a stormwater general permit should be obtained.
3. Point source discharges of wastewater from in-stream sand mining operations (typically
dredging/draglines) as stated in 15A NCAC 2H .0103 (18) and any other discharge of similar
characteristics as decided by the Division. Incidental stormwater associated with the sand mining - -
activities, i.e.stormwater which comes into contact with sand piles or drains to settling ponds.
Page 3 of 17

General Permit NCG520000 ,
4. Discharges covered by this General permit are located at any place wifbin:the political boundary of
the State of North Carolina (discharges located on the Cherokee Indian Tribal Reservation are
subject to permitting by the US Environmental Protection Agency and.are not covered by this
General Permit).
5. All surface waters of the State of North Carolina or separate storm sewer systems conveying water to
surface waters.
6. Discharge will consist of
• Surface or groundwater discharged from an, in-stream sand mining operation (typically
dredging/draglines)and similar wastewaters as decided by the Division.
Stormwater associated with the sand mining operation. For example, natural runoff from
sand piles or entering settling ponds. Separate and distinct stormwater discharges from other
parts of the mining site will be regulated under an additional storznwater general permit.
There are no additives or pollutants discharged by this type of facility. The Division's primary
concerns are suspended solids and turbidity in the receiving stream caused by the dredging
action.
7. This type of facility typically has settling ponds or lagoons to lower the settleable solids and
turbidity levels of the wastewater.
SECTION D. NOTICE OF INTENT
General Permit Expiration
General permits will be effective for a term not to exceed five years,at the end of which the Division may renew them
after all public notice requirements have been satisfied. If a general permit is renewed,existing permittees do not need to
