Dillsboro Reservoir Sand Mining Project
NCG520000—NPDES General Permit
Dear Mr. Isbanioly,
Regarding the Dillsboro Reservoir Sand Dredging Project in relation to NPDES NCG52000 General
Permit requirements, it is the opinion of this office that the subject activity will not be required to obtain
NPDES NGG520000 prior to beginning work. The Project is of very limited duration, specifically the Project
is scheduled to begin in July of 2008 and continue until December 2008. For this reason a formal application
for and approval of a NPDES NCG520000 permit will not be required. However, all permit conditions must
be adhered to. Please refer to NCG520000 for permit requirements.
This letter does not absolve nor address other permit requirements including but not limited to erosion
and sedimentation control, 401 WQC, etc. If you have any questions do not hesitate to contact me at(828)
296-4665,
Sincerely,

NCG520000- NPDES General Permit Statement of Compliance
Dear Ms. Silvis:
This correspondence is in regards to our January 24, 2008 conversation concerning the Dillsboro
Reservoir Sand Dredging Project (Project) National Pollutant Discharge Elimination System
(NPDES) obligations. The following letter and attachments discuss the Project in general and detail
NPDES permit compliance efforts for the sand mining facilities.
As you are aware, Duke Energy Carolinas, LLC(Duke)is in the planning and permitting phase of the
Dillsboro Dam Removal Project. Duke has contracted with Devine Tarbell &Associates, Inc (DTA)
to perform all engineering, scientific, and regulatory services. Duke operates the Dillsboro
Hydroelectric Project under a license from the Federal Energy Regulatory Commission (FERC)
(FERC No. 2602). The existing license expired in 2005, and the process of obtaining a subsequent
license officially began in 2000 with Duke's release of the First Stage Consultation Document.
As part of the Nantahala and Tuckasegee Relicensing Settlement Agreements (FERC No. 2692 and
2686) and agreed to by the majority of the stakeholders', Duke has proposed to surrender the license
and subsequently remove the Dillsboro Dam and Powerhouse. A License Surrender Application for
the Dillsboro Project was submitted to the FERC in early June 2004. This application included the
' American Whitewater Affiliation, Big Choga Homeowners Association, Carolina Canoe Club, DPNA, Eastern Band of
Cherokee Indians, Mountain Shadows Homeowners Association, Nantahala Community, Nantahala Gorge Association,
Nantahala Highlands Estates Property Owners Association, Nantahala Outdoor Center, Nantahala Racing Club, Natural
Resources Conservation Service, North Carolina Department of Environment and Natural Resources INC Division of Water
Resources, NC Division of Parks & Recreation, NC Division of Water Quality), North Carolina Wildlife Federation, North
Carolina Wildlife Resources Commission, Southwestern North Carolina Resource Conservation and Development Council,
Swain County Economic Development Commission, Swain County Soil and Water Conservation District, North Carolina
Council of Trout Unlimited,Inc.,United States Fish&Wildlife Service,and the United Slates Forest Service.

rationale for surrendering the Project, a Project decommissioning plan, consultation record, and
Biological and Environmental Assessment. In May of 2005, the North Carolina Division of Water
Quality(DWQ) issued a 401 Water Quality Certification(WQC) for the FERC licensing phase of the
Project. In response to the filing, the FERC issued the Draft and Final Environmental Assessments
in May and July of 2006, respectively.
In August of 2006, the U.S. Fish and Wildlife Service (USFWS) issued its Biological Opinion (BO),
which included "takings" provisions under the Endangered Species Act section 7 (16 U.S.0 1536
(c)), recommendations, and terms. The FERC issued its surrender order in August of 2007. The
DWQ issued a 401 WQC with conditions for the section 404 dredging phase of the project in
November of 2007 (attached). Condition 6 of the dredging 401 WQC states that:
"Duke Power shall remove 70,000 cubic yards of sediment from behind the dam before
the dam structure is completely removed. The total amount to be removed may be
altered only if there is less than 70,000 cubic yards of sediment available for removal or
if additional materials are required for bank stabilization. Any deviations below the
70,000 cubic yards must be approved by the Division of Water. This material shall be
disposed of in an upland disposal site(s) or sold to be used in upland sites"
In support of this condition and to minimize impacts to the resource, Duke developed a reservoir
dredging plan and identified a contractor (Carolina Sand Inc.) to perform the dredging operation.
DTA submitted a Sand Mining Permit application (currently under review) to the North Carolina
Division of Land Resources on behalf of Carolina Sand Inc.
The dredging project is constrained by two timetables. The overarching schedule of the dam removal
project, which will begin in January 2009, dictates that all dredging must be completed in 2008.
Additionally, based on Duke's Shoreline Management Guidelines, sand mining or dredging will not
be allowed from March through June. Thus, the mining activity is projected to commence in July
2008 and continue through December 2008. The objective will be to remove the targeted sediment
during this five-to six-month period.
Please find enclosed with this letter the 401 WQC with additional conditions, plan drawings for the
dredging facilities (i.e., settling basins and sediment and erosion controls) with calculations and
accompanying explanatory narrative, and a Statement of Compliance with all NPDES requirements.

EROSION AND SEDIMENT CONTROL PLAN
NARRATIVE
The design drawings (Figures 1 through 3) included in this attachment describe the erosion and
sediment control(ESC) plan for the Dillsboro Reservoir Dredging Project. The project is located
in Jackson County, North Carolina. This project ESC plan is being submitted for review and
approval prior to the commencement of land disturbing activities. The following discussion.
introduces the calculations on the drawings contained in this appendix, and explains site-specific
items relevant to the ESC plan.
The Dillsboro Reservoir Dredging Project proposes to remove a large amount of river bottom
sediment from behind the Dillsboro Dam prior to the dam's removal. A small parcel of land
along the reservoir just above Dillsboro Dam will provide the necessary area for Carolina Sand
Inc. operations. This site will contain two temporary basins; one settling basin in which the sand
will be collected, and one clarifying basin in which the fines will be collected. The clarifying
basin will also function as the sediment basin for the site's ESC plan.
Implementation of the ESC plan for the site will begin with a silt fence sediment barrier installed
around the perimeter, to be located such that it stays 10 feet from the edge of water.
Additionally, a second silt fence sediment barrier will be installed around the organic and silt
screening pile but inside the exterior site perimeter sediment barrier. The site perimeter sediment
barrier and the sediment barrier around the organic and silt screening pile will have rock outlets
to provide passage of water after settlement of the sediment has occurred.
The existing access road to the site, located approximately at the T-intersection of Momoe
Buchanan Road and Mockingbird Lane, will be utilized to enter and exit the project area. The
access road will be constructed to follow Section 6.06 of the North Carolina Erosion and
Sediment Control Planning and Design Manual guideline for temporary gravel construction
entrance/exit as shown on Figure 2.
The existing drainage for the site currently flows from the reservoir's edge towards the road, and
the proposed site will be graded toward a central basin to prevent runoff into the river from
inside the site perimeter sediment barrier. Two culverts cross Mockingbird Lane and discharge
onto the site. Because the water has runoff from undisturbed land, the culverts will be extended
and routed off the site to a riprap apron prior to being released into the reservoir. Either a
corrugated metal pipe (CMP) elbow acid T-connection or two concrete junction boxes will be
used to keep the runoff from entering the site. As necessary, additional surface water flow
barriers will be field located at the perimeter to ensure that no surface runoff will leave the
perimeter without passing through the sediment basin. In the event that this self-contained
drainage design requires field located sump pumps to provide a dry work site, all pumps will
discharge into the sediment basin.
Specific design calculation considerations are discussed below for the settling basin and the
sediment(clarifying)basin.
1. Settling basin
The temporary settling basin is sized using an estimated 3 cubic feet per second (cfs)
pumping rate from the dredge barge provided by Mr. Wayne Cassavaugh of Carolina Sand
Inc. Depending on season, the operation is anticipated to run between 8 to 10 hours per day.
The percentage of sand within the volume pumped is estimated to be 20 percent. The riser-
only settling basin outlet design provides that only water will decant into the clarifying basin.
Both the riser and the culvert pipes will be made of high density polyethylene (HDPE)
material. The sand is to be removed daily from the settling basin.
2. Sediment (Clarifying)basin
Sediment basin inflows are calculated using the U.S. Department of Agriculture-National
Resource Conservation Service's Win TR-55 Small Watershed Hydrology software package.
The sediment basin drainage area is the 3.5 acre site. The road forming the southeast boarder
of the site drains away from the site into two culverts that cross under the road. These
culverts will be extended to bypass the site. The other site drainage area border is the
reservoir. The site land use type is newly graded pervious soil with no vegetation. A time of
concentration (Tc) of 0.10 hour is used for the basin drainage area. The curve number is
from Table 8.03(e) of the North Carolina Erosion and Sediment Control Planning and
Design Manual, dated June 1, 2006. The design storm is a 24-hour, 25-year recurrence
rainfall event with intensities for the city of Asheville from Table 8.030) of the Erosion and
Sediment Control Planning and Design Manual. The output for TR-20 and TR-55 are
included in this appendix.
Using the disturbed area and peak inflow discussed above, the required size of the sediment
basin is determined based on the design criteria of Section 6.61 of the North Carolina
Erosion and Sediment Control Planning and Design Manual, dated June 1, 2006, with the
exception that a 25-year (rather than a 10-year) design storm is used for this design.
Sediment basin sizing results are smmnarized on the drawings, and the required sediment
basin surface areas and volumes are compared with those provided by the sediment basin
shown on the drawings. The sediment basin's emergency spillway is an HDPE vertical riser,
which is sized to pass the 25-year peak flow rate. This spillway capacity combined with a
basin volume sufficient to contain the 25-year storm volume without spilling is a
conservative basin design. The sediment basin's normal outlet is a skimmer, which is sized
to provide more than one full day for the sediment to settle per Section 6.64 of the Erosion
and Sediment Control Planning and Design Manual. The dredging flow rate is included in
the skimmer design but not in the spillway design because it is assumed that in-river
dredging activity would be curtailed during a 25-year stoma event.
The sediment basin will be field located at the lowest elevation possible. The sediment basin
bottom elevation (nominally 0.0 foot on the drawing) will be 0.5 foot above the normal full
reservoir elevation of the Dillsboro reservoir to allow for sediment basin maintenance. Since
the normal full pond elevation of Dillsboro is 1972.0 feet MSL, the expected elevation of the
sediment basin bottom will be approximately 1972.5 feet MSL.
The elements of the ESC plan described on the drawings and in this appendix are designed to
work together to prevent and contain site sedimentation associated with the activities of the
Dillsbom Dam Dredging Project. If you have any questions or need additional information,
please contact Stephen R. Gaffney, P.E. at (704) 342-7311 or by email at

NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM
PERMIT REQUIREMENTS
STATEMENT OF COMPLIANCE
PART I - MONITORING CONTROLS AND LIMITATIONS FOR PERMITTED
DISCHARGES
A) EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS
i) Settleable solids - The monthly average shall not exceed 5.0m1/L and the daily
maximum shall not exceed 10.0 ml/L. Measuring shall be a semi-annual grab sample
of the effluent.
ii) Turbidity- The discharge shall not cause an instantaneous measurement of the turbidity
of the receiving water to exceed 10 NTU (trout waters). If the background turbidity
exceeds 10 NTU, the discharge shall not cause an increase in the turbidity of the
receiving waters.
iii) pH - The pH shall not be less than 6.0 standard units nor greater than 9.0 standard units
for freshwater classifications.
iv) No organic debris (e.g., sticks, leaves) removed to the shore shall be returned to any
surface waters. All such materials shall either be sold for approved commercial use
(e.g, landscaping) or deposited at the Jackson County Solid Waste Department
Transfer Station, located in Sylva,North Carolina.
v) The permittee shall operate the facility.
vi) Impacts to surface waters shall be minimized through sound management practices.
vii) There shall be no discharge of floating solids or visible foam in other than trace
amounts.
B) SCHEDULE OF COMPLIANCE
i) The permittee shall comply with Final Effluent Limitations by the effective coverage
date.
ii) The permittee shall at all times provide for the operation and maintenance necessary to
operate the existing facilities in Part II.C.2 of the permit requirements.
C) APPLICABLITY
i) The Dillsboro Sand Mining Project is an in-stream mining operation using a hydraulic
vacuum dredger. Wastewater discussed in this document is the water decanted from
the settling and clarifying ponds.
ii) No other stormwater outfalls shall be diverted to the settling ponds. Roadside culverts
extending onto the site shall be piped through the area and shall not be treated in the
settling ponds. -
D) NOTICE OF INTENT
This is not a Notice of Intent, but rather a Certification of Compliance, and therefore not all of
the information requested in Section D is applicable.
i) Wayne Cassavaugh, Carolina Sand Inc., 2440 Angus Lane, Lenoir, NC 28645
(828) 728-6815.
ii) Dillsboro Reservoir Sand Mine, Wayne Cassavaugh, Mockingbird Lane, Dillsboro,
NC, 28725, (828) 728-6815
iii) N/A
iv) The discharge shall be limited to water decanted from sand and sediment withdrawn
from the Dillsboro Reservoir. There shall be one (1) discharge point that can carry
approximately 20 MOD. However, because the sand dredging will only take place for
8 to 10 hours per day for 6 days per week, the actual amount of discharge will be much
less than maximum capacity. In addition to extended settling time, approved
flocculents may be used to improve discharge water quality. Please refer to the
attached stormwater management narrative and drawings for facility details and
calculations.
v) The Dillsboro Reservoir is the receiving waters and is part of the Tuckasegee River.
The stream classification at this point is C-Trout.
vi) Due to site size constraints (3.5 acres), the nature of the discharge (i.e., non-oxygen-
consuming waste), and the temporary nature of the project (6 months), no other
discharge disposal methods are feasible and therefore do not warrant a comparative
analysis.
vii) Please refer to the enclosed drawings and maps.
viii) Please refer to the enclosed drawings, calculations, and narrative.
ix) All information provided within this Certification of Compliance is true, complete, and
