Dear Mr. Wise:
On April 25, 2017, the Department of the Army issued a permit to Duke Energy for
the Cedar Cliff Auxiliary Spillway Upgrades Project in Tuckasegee, Jackson County,
North Carolina. The Corps issued a modification to this permit on June 21, 2019. A
written request for a second permit modification was received on August 5, 2020. This
request involves authorization for additional impacts associated with further
improvements to the Cedar Cliff public access area.
The permit is modified to include the impacts for a temporary rip rap apron and
excavation of accumulated lake sediment, as shown on the enclosed plans. These
impacts consist of 0.14 acres of temporary impacts to open waters and 0.007 acres of
permanent impacts to open waters. The total authorized open water impacts for this
action are now 52.42 acres of temporary open water impacts and 10.567 acres of
permanent open water impacts.
The permit is hereby modified to include the work as noted above. All conditions of
the original permit remain applicable and the expiration date is unchanged.
FOR THE COMMANDER

THE SURFACE OF THE RECEIVING CHANNEL. THE
APRON SHALL HAVE A CUTOFF OR TOE WALL AT THE
DOWNSTREAM END.
4. THE WIDTH OF THE END OF THE APRON SHALL BE
EQUAL TO THE BOTTOM WIDTH OF THE RECEIVING
CHANNEL. MAXIMUM TAPER TO RECEIVING CHANNEL
5. ALL SUBGRADE FILL FOR STRUCTURE TO BE
COMPACTED TO 95% OF THE STANDARD PROCTOR
MAXIMUM DRY DENSITY OR TO THE DENSITY OF THE
SURROUNDING UNDISTURBED MATERIAL.
6. THE PLACING OF FILL, EITHER LOOSE OR COMPACTED,
IN THE RECEIVING CHANNEL SHALL NOT BE ALLOWED.
7. NO BENDS OR CURVES IN THE HORIZONTAL
ALIGNMENT OF THE APRON UNLESS OTHERWISE
SHOWN.
8. TYPE 1 GEOTEXTILE FILTER FABRIC SHALL BE
INSTALLED ON COMPACTED SUBGRADE PRIOR TO
PLACEMENT OF RIPRAP.
9. ANY DISTURBED AREA FROM END OF APRON TO

BIODEGRADABLE FILLER MATERIALS AND SHALL CONFORM TO THE REQUIREMENTS IN
ASTM DESIGNATION: E 204
2. THE SEDIMENT FILTER BAG SHALL BE 10'X12'X1.5' (MIN) AND SHALL BE COMPLETE WITH LIFTING LOOPS
AND DUMP STRAPS ATTACHED AT THE BOTTOM TO FACILITATE EMPTYING OF THE SEDIMENT FILTER BAG.
3. LIFTING STRAPS SHOULD BE PLACED UNDER THE DEWATERING SEDIMENT FILTER BAG TO FACILITATE
REMOVAL AFTER USE.
4. PLACE THE DEWATERING SEDIMENT FILTER BAG ON A LEVEL STABILIZED AREA OVER DENSE
VEGETATION/STRAW, OR GRAVEL (IF INCREASED DRAINAGE SURFACE AREA IS NEEDED).
5. INSERT DISCHARGE HOSE FROM PUMP INTO THE DEWATERING SEDIMENT FILTER BAG A MINIMUM OF 6
INCHES AND TIGHTLY SECURE WITH ATTACHED STRAP TO PREVENT WATER FROM FLOWING OUT OF THE
UNIT WITHOUT BEING FILTERED.
6. REPLACE THE UNIT WHEN 1 /2 FULL OF SEDIMENT OR WHEN SEDIMENT HAS REDUCED THE FLOW RATE
OF THE PUMP DISCHARGE TO AN IMPRACTICAL RATE.
7. REMOVE THE UNIT AND SEDIMENT FROM ENVIRONMENTALLY SENSITIVE AREA AND WATERWAYS. AT THE
APPROVED DISPOSAL SITE, OPEN OR SLIT THE UNIT, REMOVE SEDIMENT AND GRADE SMOOTHLY INTO
EXISTING TOPOGRAPHY. DISPOSE OF THE DEWATERING SEDIMENT FILTER BAG, AT AN APPROPRIATE
RECYCLING OR SOLID WASTE FACILITY.
8. INSTALL ROCK BERM AROUND FILTER BAG.

NOTES:
1. ALL CHANNEL WORK INVOLVING EXCAVATION SHALL BE PERFORMED IN DRY
CONDITIONS OR IN CHANNEL SECTIONS ISOLATED BY IMPERVIOUS DIKES AND
KEPT DE -WATERED.
2. THE CONTRACTOR SHALL NOT DISTURB MORE AREA THAN CAN BE STABILIZED
THE SAME WORKING DAY.
3. PUMP -AROUND PUMP AND HOSE SHALL ADEQUATELY CONVEY BASEFLOW
(CONTRACTOR TO VERIFY). DE -WATERING PUMP SHALL ADEQUATELY DE -WATER
THE WORKING AREA AT THE DOWNSTREAM IMPERVIOUS DIKE.
4. GRAVITY -BASED GEOTEXTILE BAG FILTERS SHALL BE USED TO COLLECT SILT AND
SEDIMENT FROM WORK AREA DE -WATERING. THE DESIGNER MAY SPECIFY A
SEDIMENT BASIN OR OTHER SEDIMENT CONTROL MEASURE IN LIEU OF A
SEDIMENT BAG IF SITE CONDITIONS ARE FAVORABLE (I.E. - TREES WILL NOT BE
IMPACTED FOR BASIN EXCAVATION, ETC.).
5. EFFLUENT FROM CLEAN WATER PUMP AROUND MAY BE DISCHARGED DIRECTLY
INTO STABILIZED OUTLET (NO SEDIMENT REMOVAL DEVICE REQUIRED).
6. A STABILIZED OUTLET SHALL BE USED TO CONTROL THE EFFLUENT FROM ALL
PUMPING OPERATIONS. THE DESIGNER SHALL SPECIFY ALL MATERIALS AND
DIMENSIONS ASSOCIATED WITH STABILIZED OUTLETS.
7. FILTER FABRIC AS SPECIFIED BY THE DESIGNER SHALL BE USED UNDERNEATH
ALL STONE/RIP RAP PLACED FOR SEDIMENT BAGS, STABILIZED OUTLETS, SPLASH
PADS.
8. IMPERVIOUS DIKES SHALL BE CONSTRUCTED TO ISOLATE THE IN -STREAM
WORKING AREA. AN IMPERVIOUS FABRIC MEMBRANE AND SAND BAGS OR STONE,
AS SPECIFIED BY THE DESIGNER, SHALL BE USED TO CREATE THE DIKES. ADD
BENTONITE AS NEEDED TO REDUCE FLOW THROUGH AND AROUND IMPERVIOUS
DIKE.
9. INSTALL FLOAT SYSTEM WITH AUTOMATIC PUMP START.
10. PROVIDE 24 HR MONITORING DURING PUMP AROUND OPERATION.
11. THE WORK SEQUENCE IN PUMP -AROUND OPERATIONS PROCEEDS TYPICALLY AS
FOLLOWS:
A. INSTALL SEDIMENT REMOVAL DEVICE AND TEMPORARY STABILIZED OUTLETS
AT THE DOWNSTREAM END OF WORKING AREA.
B. INSTALL PUMP -AROUND PUMP AND FLEXIBLE HOSE.
C. INSTALL UPSTREAM IMPERVIOUS DIKE AND BEGIN PUMPING (CLEAN WATER)
DOWNSTREAM TO STABILIZED OUTLET.
D. INSTALL DOWNSTREAM IMPERVIOUS DIKE AND DE -WATERING PUMP.
E. PERFORM CHANNEL WORK IN ACCORDANCE WITH THE PLANS IN THE
WORKING AREA.
F. DE -WATER THE WORKING AREA (AS NEEDED) INTO THE SEDIMENT REMOVAL
DEVICE AND TEMPORARY STABILIZED OUTLET.
G. UPON COMPLETION OF WORK, REMOVE ANY SEDIMENT ACCUMULATION
BEHIND IMPERVIOUS DIKES.
H. REMOVE DOWNSTREAM AND THEN UPSTREAM DIKES AND ALL PUMPS AND
HOSE.
I. SEED AND MULCH ALL DISTURBED AREAS PER THE PLANTING PLAN.
J. REMOVE ALL PUMP AROUND MEASURES AND RESTORE AREA TO EXISTING
CONDITIONS OR PER PLAN DESIGN IF APPLICABLE.
