are forwarding herewith the,subject certificate of coverage (COC) to discharge under the subject
state — NPDES general permit. This permit is issued pursuant to the requirements of North
Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina
and the US Environmental Protection Agency dated October 15, 2007 (or as subsequently
amended).
Please take notice that this certificate of coverage is not transferable except after notice to
the Division of Water Quality. The Division of Water Quality may require modification or
revocation and reissuance of the certificate of coverage.
Please note that mine dewatering wastewater includes wet pit overflows caused _solely
by direct rainfall and groundwater seepage for this type of mining operation. Any discharge of
this water (and any stormwater commingled with it) is subject to the effluent limitations in this
permit.
The nearest named receiving stream is classified as High Quality Waters (HQW), as
noted on the COC. However, at this time the Division has determined that a flow limit (Part III,
Table 8.) is not applicable because of the location of the wastewater outfalls. Please maintain
this letter with your permit records for reference.
This general pen -nit allows the discharge of stonnwater and certain types of wastewater
from your facility. If separate point -source discharges of stormwater occur (i.e., stonnwater not
combined with mine dewatering water), you will be required to adhere to the conditions in this
permit for stonnwater discharges.

Subject: RE: SW General Permit NCG020820
Brian,
i think the analytical monitoring parameters for stoimwater between the NCG02 and NCG16 are too different to cover
this site under just the NCG02. The NCG16 has pH and Total Petroleum Hydrocarbons, which are important parameters
for the asphalt plants. So unless we cover this site under an Individual Stormwater Permit, which I doubt Riley Paving
would want, we should move forward with coverage under the two general permits. They need to be very clear on
which outfalls are receiving stormwater flow from the asphalt plant versus the mining activities and monitor them
accordingly. However, their site may be set up in a way that stormwater flow from each industrial activity is commingled
prior to discharge. So I'm not sure how they would comply with the monitoring requirements under each permit.

Hey Mike,
We can issue two permits to the same facility if they have two different industrial activities that need to he covered.
Sometimes we cover them just under the more protective one or give them an individual. Do you think we could cover
Moth activities under that NCG02? Thanks for the copy of the mining permit review. Based on our permit the skimmer
discharge would meet the definition of dewatering for sand pits so I am planning on writing the permit for dewatering.

Brian,
As FYI, there is a Riley Paving asphalt plant at this same location (same address), which has coverage under NCG160187.
Does that have any effect on us issuing coverage for the same location under an additional separate permit? Also, I've
attached my review sheet as part of the DLR mining permit application process where I commented that they proposed
4 skimmer basins for stormwater discharges, but did not propose any mine dewatering. Don't know if this has any
bearing on your conversation with the engineer. Just wanted you to have a copy of the review sheet in case you don't
already.
Unless there is some reason we can't/don't issue two separate permits for the same location, we have no objections to
issuance of a COC.
Thanks,

Subject: SW General Permit NCG020820
Mike,
We've received an NOI from James Riley (Riley Paving Inc) for their site Riley Sand Pit in Carthage, Moore County, for
coverage under an NCG02. The site discharges stormwater to a Drowning Creek (C; Sw, HQW). I have attached the
NOI. The NOI said there was no mine dewatering but the plans show the pits have skimmers that draw down the water.
I talked to the engineer and informed him we would have to write the permit for mine dewatering water and he was fine
with that. Do you want me to forward you a copy of the plans?
Please let me know if the Fayetteville Regional Office has any concerns about issuing this facility a COC for this general
permit, and are there any potential impacts to wetlands? If we don't receive any objections, we'll issue the COC in 30
days.
Thanks,
Brian

already.
Unless there is some reason we can't/don't issue two separate permits for the same location, we have no objections to
issuance of a COC.
Thanks,

Mike,
We've received an NOI from James Riley (Riley Paving Inc) for their site Riley Sand Pit in Carthage, Moore County, for
coverage under an NCG02, The site discharges stormwater to a Drowning Creek (C; Sw, HQW). I have attached the
NOI. The NOI said there was no mine dewatering but the plans show the pits have skimmers that draw down the water.
I talked to the engineer and informed him we would have to write the permit for mine dewatering water and he was fine
with that. Do you want me to forward you a copy of the plans?

Please let me know if the Fayetteville Regional Office has any concerns'about issuing this facility a COC for this general
permit, and are there any potential impacts to wetlands? If we don't receive any objections, we'll issue the COC in 30
days.
Thanks,
Brian

1. Weir length sized to pass the peak discharge from the 25 year storm.
2. Required Surface Area (SA) is derived by using 325 square feet per cfs based on the 025 design storm
3. Maximum depth of flow in spillway = 0.5 ft., Maximum constructed depth in spU way = 1.5 ft., and minimum freeboard = 1.0 ft.
4. Time of Concentration typically 5 minutes.
5, Required storage is derived by muftliing the disturbed area by 1800 cubic feettacre

Precipitation frequency (PF) estimates in this tabia are based on frequency analysis of partial duration series (POS).
Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval the probability that pre6pitatlon frequency estimates (for a
given duration and average recurrence interval) VAI be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not
checked against probable rniaArinurn precipitation (PMP) estimates and may be higher than currently valid PMP values.

stormwater contaminated with or that has come in contact with, any overburden, raw material, intermediate
products, finished products, byproducts or waste products located on the site of such operations;
• Stormwater from vehicle maintenance activities at mining operations;
• Overflow from facilities that recycle process wastewater; and/or
• Mine dewatering (wastewater)
The following activities are specifically excluded from coverage under this General Permit:
• Stormwater discharges associated with peat mining, coal mining, and metal mining;��� Do
Stormwater discharges from mining operations which are intermixed on site with stor t operations and/or concrete operations;
• Stormwater discharges associated with oil and gas extraction operations; and APR 4 2012
• Stormwater discharges associated with tourist gem mines
• NCDOT borrow pits are covered under NGS000150 I
DENit - WATER Qu11Lli
The following discharges are covered by NPDES general permit NCG520000 instea of IgCGD2D .
• Point source discharges of stormwater and wastewater from in -stream sand mining operations (i.e., sand
dredging or dipping operations) _
For new mining sites that require an authorization to construct (ATC) wastewater treatment facilities: This
NOl is also an APPLICATION FOR an ATC for new wastewater treatment facilities. ATC requests must be
submitted at least 90 days'prior to construction'.
For existing mining sites that require an Authorization to Operate (ATO) wastewater treatment facilities:
This NOI is also an APPLICATION FOR an ATO for wastewater treatment facilities in place.
Construction, modification, or installation of any new treatment components at an existing site requires an
ATC. (If the site is already covered by NCG020000, the ATC request may be submitted without an NOI).
Some wastewater treatment facilities used to treat or recycle wastewater at mining sites will require an ATC rp for
to construction per 15A NCAC 2H .0138. Please see the NCG020000 General Permit for details about which
treatment facilities require an ATC (summarized in Table 1 below). The authorization to construct or continue
to operate will be issued at the same time as the Certificate of Coverage (COC) for the NCG02 permit. Design of
treatment facilities must comply with requirements of 15A NCAC 2H .0138 & .0139.
Construction of wastewater treatment facilities subject to the ATC/ATO requirements in the NCG02 permit
at new or existing mining sites requires submission of three (3) sets of plans and specifications signed

RE: Riley Sand Pit
Richmond County
Lumber River Basin
Dear Mr. Riley:
Michael F. Easley, Governor
William G. Rass Jr., Secretary
The application for a mining permit for the above referenced mine site has been found to
meet the requirements of GS 74-51 of The Mining Act of 1971. As we have received the required
security to cover this application, I am enclosing the mining permit.
The conditions of Mining Permit No. 77-23 were based primarily upon information supplied
in the application with conditions added as necessary to insure compliance with The Mining Act
of 1971. This permit expires on June 6, 2012. GS 74-65 states that the Issuance of a mining
permit does not supersede or otherwise affect or prevent the enforcement of any zoning
regulation or ordinance duly adopted by an incorporated city or county or by any agency or
department of the State of North Carolina.
As a reminder, your permitted acreage at this site is 51.15 acres and the amount of land
you are approved to disturb is 42.5 acres.
Please review the permit and notify this office at [phone] of any objection or
questions concerning the terms of the permit.
Sincerely,
racy E. vis, P.E., C.P.M.

CONSTRUCTION SPECIFICATIONS.-
1 . CLEAR, GRUB, AND STRIP AREA UNDER THE EMBANKMENT OF ALL VEGETATION
AND ROOT MAT. REMOVE ALL SURFACE SOIL CONTAINING HIGH AMOUNTS OF
ORGANIC MATTER AND STOCKPILE OR DISPOSE OF IT PROPERLY. HAUL ALL OBJECTIONABLE
MATERIAL TO THE DESIGNATED DISPOSAL AREA, PLACE TEMPORARY SEDIMENT CONTROL
MEASURES BELOW BASIN AS NEEDED.
2. ENSURE THAT FILL MATERIAL FOR THE EMBANKMENT IS FREE OF ROOTS, WOODY
VEGETATION, ORGANIC MATTER, AND OTHER OBJECTIONABLE MATERIAL. PLACE THE FILL
IN LIFTS NOT TO EXCEED 9 INCHES, AND MACHINE COMPACT IT. OVER FILL THE
EMBANKMENT 6 INCHES TO ALLOW FOR SETTLEMENT.
3. SHAPE THE BASIN TO THE SPECIFIED DIMENSIONS. PREVENT THE SKIMMING DEVICE
FROM SETTLING INTO THE MUD BY EXCAVATING A SHALLOW PIT UNDER THE SKIMMER OR
PROVIDING A LOW SUPPORT UNDER THE SKIMMER OF STONE OR TIMBER.
4. PLACE THE BARREL (TYPICALLY 4-INCH SCHEDULE 40 PVC PIPE) ON A FIRM, SMOOTH
FOUNDATION OF IMPERVIOUS SOIL. DO NOT USE PREVIOUS MATERIAL SUCH AS SAND,
GRAVEL, OR CRUSHED STONE AS A BACK FILL AROUND THE PIPE. PLACE THE FILL
MATERIAL AROUND THE PIPE SPILLWAY IN 4--INCH LAYERS AND COMPACT IT UNDER AND
AROUND THE PIPE TO AT LEAST THE SAME DENSITY AS THE ADJACENT EMBANKMENT. CARE
MUST BE TAKEN NOT TO RAISE THE PIPE FROM THE FIRM CONTRACT WITH ITS
FOUNDATION WHEN COMPACTING UNDER THE PIPE HAUNCHES.
PLACE A MINIMUM DEPTH OF 2 FEET OF COMPACTED BACK FILL OVER THE PIPE SPILLWAY
BEFORE CROSSING IT WITH CONSTRUCTION EQUIPMENT, IN NO CASE SHOULD THE PIPE
CONDUIT BE INSTALLED BY CUTTING A TRENCH THROUGH THE DAM AFTER THE
EMBANKMENT IS COMPLETE.
5. ASSEMBLE THE SKIMMER FOLLOWING THE MANUFACTURES INSTRUCTIONS, OR AS
DESIGNED.
S. LAY THE ASSEMBLED SKIMMER ON THE BOTTOM OF THE BASIN WITH THE FLEXIBLE
JOINT AT THE INLET OF THE BARREL PIPE. ATTACH THE FLEXIBLE JOINT TO THE BARREL
PIPE AND POSITION THE SKIMMER OVER THE EXCAVATED PIT OR SUPPORT. BE SURE TO
ATTACH A ROPE TO THE SKIMMER AND ANCHOR IT TO THE SIDE OF THE BASIN. THIS WILL
BE USED TO PULL THE SKIMMER TO THE SIDE FOR MAINTENANCE.
7. EARTHEN SPILLWAYS - INSTALL THE SPILLWAY IN UNDISTURBED SOIL TO THE GREATEST
EXTENT POSSIBLE. THE ACHIEVEMENT OF PLANNED ELEVATIONS, GRADE, DESIGN WIDTH,
AND ENTRANCE AND EXIT CHANNEL SLOPES ARE CRITICAL TO THE SUCCESSFUL OPERATION
OF THE SPILLWAY. THE SPILLWAY SHOULD BE LINED WITH THE LAMINATED PLASTIC OR
IMPERMEABLE GEO TEXTILE FABRIC. THE FABRIC MUST BE WIDE AND LONG ENOUGH TO
COVER THE BOTTOM AND SIDES AND EXTEND ONTO THE TOP OF THE DAM FOR
ANCHORING IN A TRENCH. THE EDGES MAY BE SECURED WITH 8--INCH STAPLES OR PINS.
THE FABRIC MUST BE LONG ENOUGH TO EXTEND DOWN THE SLOPE AND EXIT ONTO
STABLE GROUND. THE WIDTH OF THE FABRIC MUST BE ONE PIECE, NOT JOINED OR
SPLICED; OTHERWISE WATER CAN GET UNDER THE FABRIC. IF THE LENGTH OF THE FABRIC
IS INSUFFICIENT FOR THE ENTIRE LENGTH OF THE SPILLWAY, MULTIPLE SECTIONS,
SPANNING THE COMPLETE WIDTH, MAY BE USED. THE UPPER SECTIONS SHOULD OVERLAP
THE LOWER SECTIONS SO THAT WATER CANNOT FLOW UNDER THE FABRIC. SECURE THE
UPPER EDGE AND SIDES OF THE FABRIC IN A TRENCH WITH STAPLES OR PINS. (ADAPTED
FROM " A MANUAL FOR DESIGNING, INSTALLING AND MAINTAINING SKIMMER SEDIMENT
BASINS." FEBRUARY 1999 J.W. FAIR CLOTH & SON.)
8. INLETS - DISCHARGE WATER INTO THE BASIN IN A MANNER TO PREVENT EROSION. USE
TEMPORARY SLOPE DRAINS OR DIVERSIONS WITH OUTLET PROTECTION TO DIVERT SEDIMENT
INFL(
LADEN WATER TO THE UPPER END OF THE POOL AREA TO IMPROVE BASIN TRAP
STRU
EFFICIENCY (REFERENCES: RUNOFF CONTROL MEASURES AND OUTLET PROTECTION).
9. EROSION CONTROL - CONSTRUCT THE STRUCTURE SO THAT THE DISTURBED AREA IS
MINIMIZED. DIVERT SURFACE WATER AWAY FROM BARE AREAS. COMPLETE THE EMBANKMENT
BEFORE THE AREA IS CLEARED. STABILIZE THE EMERGENCY SPILLWAY EMBANKMENT AND
ALL OTHER DISTURBED AREAS ABOVE THE CREST OF THE PRINCIPAL SPILLWAY IMMEDIATELY
AFTER CONSTRUCTION ( REFERENCES: SURFACE STABILIZATION).
10. INSTALL POROUS BAFFLES AS SPECIFIED IN PRACTICE 6.65
11. AFTER ALL THE SEDIMENT --PRODUCING AREAS HAVE BEEN PERMANENTLY STABILIZED,
AVEF
WIDT
REMOVE THE STRUCTURE AND AIL THE UNSTABLE SEDIMENT, SMOOTH THE AREA TO BLEND
WITH THE ADJOINING AREAS AND STABILIZE PROPERLY ( REFERENCES: SURFACE
STABILIZATION).
* AR
TOP
MAINTENANCE,
INSPECT SKIMMER SEDIMENT BASINS AT LEAST WEEKLY AND AFTER EACH SIGNIFICANT
RAINFALL EVENT AND REPAIR IMMEDIATELY. REMOVE SEDIMENT AND RESTORE THE BASIN TO
ITS ORIGINAL DIMENSIONS WHEN SEDIMENT ACCUMULATES TO ONE --HALF THE HEIGHT OF
THE BATTLE. PULL THE SKIMMER TO ONE SIDE SO THAT THE SEDIMENT UNDERNEATH IT
CAN BE EXCAVATED. EXCAVATE THE SEDIMENT FROM THE ENTIRE BASIN, NOT JUST
AROUND THE SKIMMER OR THE FIRST CELL. MAKE SURE VEGETATION GROWING IN THE
BOTTOM OF THE BASIN DOES NOT HOLD DOWN THE SKIMMER.
REPAIR THE BAFFLES IF THEY ARE DAMAGED. RE --ANCHOR THE BAFFLES IF WATER IS
FLOWING UNDERNEATH OR AROUND THEM.
IF THE SKIMMER IS CLOGGED WITH TRASH AND THERE IS WATER IN THE BASIN, USUALLY
JERKING ON THE ROPE WILL MAKE THE SKIMMER BOB UP AND DOWN AND DISLODGE THE
DEBRIS AND RESTORE FLOW. IF THIS DOES NOT WORK, PULL THE SKIMMER OVER TO THE
SIDE AND REMOTE DEBRIS. ALSO CHECK THE ORIFICE INSIDE THE SKIMMER FOR DEBRIS.
IF THE SKIMMER ARM OR BARREL PIPE IS CLOGGED, THE ORIFICE CAN BE REMOVED AND
THE OBSTRUCTION CLEARED WITH A PLUMBER'S SNAKE OR BY FLUSHING WITH WATER. BE
SURE AND REPLACE THE ORIFICE BEFORE REPOSITIONING THE SKIMMER.
CHECK THE FABRIC LINED SPILLWAY FOR DAMAGE AND MAKE ANY REQUIRED REPAIRS WITH
THE FABRIC THAT SPANS THE FULL WIDTH OF THE SPILLWAY, CHECK THE EMBANKMENT,
SPILLWAYS, AND OUTLET FOR EROSION DAMAGE, AND INSPECT THE EMBANKMENT FOR
PIPING AND SETTLEMENT. MAKE ALL NECESSARY REPAIRS IMMEDIATELY. REMOVE ALL TRASH
AND OTHER DEBRIS FROM THE SKIMMER AND POOL AREAS.
FREEZING WEATHER CAN RESULT IN ICE FORMING IN THE BASIN. SOME SPECIAL
PRECAUTIONS SHOULD BE TAKEN IN THE WINTER TO PREVENT THE SKIMMER FROM
PLUGGING WITH ICE.

CONSTRUCTION NARRATIVE
THE PURPOSE FOR THIS PROJECT IS TO PRODUCE A SAND MINE FOR RILEY PAVING. THE SITE
IS LOCATED OFF OF US HWY 1 NORTH IN RICHMOND COUNTY. THE PROJECT IS BEING SENT IN
FOR REPERMITTING AND MODIFICATION TO THE EXISTING PERMIT. THE ORIGINAL PERMIT IS BEING
MODIFIED TO REMOVE THE REQUIREMENT TO WORK ON THE PROJECT CELL BY CELL AND SINCE
THE ORIGINAL PERMIT, APPROXIMATELY 3 ACRES HAS BEEN ACQUIRED BY NCDOT AND THUS
REDUCING THE ACREAGE TO BE MINED AS SHOWN ON SHEET C-2. CONSTUCTION OF THE
PERIMETER BERM IS TO BE PLACED AS SHOWN ON THE PLANS. AS THE SITE IS BROUGHT TO
FINISHED GRADE, THE EROSION CONTROL MEASURES ARE TO BE CONSTRUCTED PRIOR TO ANY
GRADING WHICH MAY RESULT IN SEDIMENT LEAVING THE SITE. DURING PROJECT WORD ALL
EROSION CONTROL DEVICES ARE TO BE PROPERLY MAINTAINED TILL FINAL STABILIZATION HAS
BEEN ACCOMPLISHED AND APPROVAL HAS BEEN AUTHORIZED BY THE SEDIMENTATION AND EROSION
CONTROL INSPECTOR. ONCE THE AUTHORIZATION HAS BEEN GIVEN TO REMOVE THE SEDIMENT
TRAPS CONSTRUCTION OF THE BIORETENTION CELLS ARE TO BE CONSTRUCTED.
