In response to your renewal application for continued coverage under Stormwater General Permit NCG120000
the Division of Water Quality (DWQ) is forwarding herewith the reissued General Permit. This permit is
reissued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of
Agreement between the state of North Carolina and the U.S. Environmental Protection Agency, dated October
15, 2007 (or as subsequently amended).
The following information is included with your permit package:
• A new Certificate of Coverage (COC)
• A copy of General Permit NCG120000
• A copy of the Technical Bulletin for the General Permit
• Two copies of the Discharge Monitoring Report (DMR) Form
• Two copies of the Qualitative Monitoring Report Form
The General Permit authorizes discharges of stormwater, and it specifies your obligations for discharge
controls, management, monitoring, and record keeping. Please review the new permit to familiarize yourself
with all the changes in the reissued permit. Your facility has six (6) months from the time of receipt of the
permit to update your current SPPP to reflect all new permit requirements.
The first sample period of your permit begins January 1, 2013. Your facility must sample a "measureable
storm event" beginning during the periods beginning January 1 and July 1 of every year (or, if applicable,
report "No Flow," as outlined in Part III, Section E). Also, please note that Tier 3 Actions in Part II of your
permit are triggered by benchmark exceedances on four occasions beginning on the effective date of this
permit and do not count prior exceedances.
The more significant changes in the General Permit since your last COC was issued are noted either in the
Draft Permit Fact Sheet that accompanied the public notice (http://portal.ncdenr.org/web/wq/ws/su/current-
notices), or in the Response to Comments / Summary of Changes and Technical Bulletin documents that are

Some of the changes include:
• Part II:
• Section A: The Stormwater Pollution Prevention Plan (SPPP) section, if applicable, has been updated
to the most current language of our permits. Additional conditions for specific industry sectors have
been added to the SPPP requirements in some cases.
• Sections B, C: Failure to perform analytical stormwater monitoring may result in the Division requiring
that the permittee begin a monthly sampling scheme.
• Sections B, C: A lower TSS benchmark of 50 mg/I for HOW, ORW, RNA and Tr Waters applies to these
more sensitive waters.
• Sections B, C: The monitoring parameter Oil & Grease (O&G) has been replaced by the parameter
Total Petroleum Hydrocarbons (TPH) for vehicle maintenance areas, and in some cases, other
analytical monitoring requirements.
• Sections B, C, D: Inability to sample due to adverse weather must be recorded in the SPPP, or in
separate on -site records if your General Permit does not require an SPPP. Adverse weather is defined
in the "Definitions" section of the permit.
• Sections B, C. The term "Representative Storm Event" has been replaced by "Measurable Storm
Event." A measurable storm event is defined in the permit.
• Section D: If the permittee fails to respond effectively to problems identified by qualitative
monitoring, DWQ may require the permittee to perform corrective action.
Please review Parts III and IV to understand the Standard Conditions of your new NPDES General Permit,
including Compliance and Liability, Reporting, Monitoring and Records requirements; Operation and
Maintenance obligations; and Definitions. Please note that all samples analyzed in accordance with the terms
of this permit must be submitted to the Division on Discharge Monitoring Report (DMR) forms available on
the Stormwater Permitting Unit's website above. DMR forms must be delivered to the Division no later than
30 days from the date the facility receives the sampling results from the laboratory. Also note that existing
permittees do not need to submit a renewal request prior to expiration unless directed by the Division.
Your coverage under the General Permit is transferable only through the specific action of DWQ. This permit
does not affect the legal requirements to obtain other permits which may be required by DENR, nor does it
relieve the permittee from responsibility for compliance with any other applicable federal, state, or local law,
rule, standard, ordinance, order, judgment, or decree. If you have any questions regarding this permit
package, please contact the Division's Stormwater Permitting Unit at (919) 807-6300.
Sincerely,/
for Charles Wakild, P.E.

• Newly cleared Construction or Building Sites
• Road and Highway construction
+ Hydroseeding and Water Truck application
• Hand spreading and Ditch placement
Features and Benefits
• Removes solubilized soils and clay from water
• Prevents colloidal solutions in water when applied to the soil surface
• Will reduce soil movement during rain event on moderate slopes
• Binds cationic metals within the soil matrix, reducing solubilization
• Reduces pesticide and fertilizer loss during rain events
• Reduces wind borne dust conditions
Increases soil permeability and water penetration to shallow plants
• Reduces operational and cleanup costs
• Reduces environmental risk and compliance
Specifications / Compliances
ANSI/NSF Standard 60 Drinking water treatment chemicals
• 48h or 96h Acute Toxicity Tests (D. magna, P. promelas, or O. mykiss)
• 7 day Chronic Toxicity Tests (P, promelas or C. dubia)
Packaging
APS 700 Series Silt Stop is packaged in 50 pound bags
Technical Information
Appearance: White granular powder
Ibs.lcubic foot Note: Dosage -application rates are determined on soil
Bulk Density: 40-50 Percent Moisture: 1 lb maximum specific testing. Soil polymers and blends should never
Pe
Pe cent solution :15 be used without testing the soil first. Consult your local
Shelf Life: up on years distributor or send your samples to Applied Polymer
Systems, Inc.
Coverage
10 -- 20 # powder 1 Acre — gentle to moderate slopes (flat to 4:1) Dry Spread Application
20 — 50 # powder 1 Acre — steep slopes (3:1 to 1:1) Dry Spread Application
3.5 — 5 # powder 1 1000 gallons water 1'13 Acre Hydroseed Applications
Directions for Use
Dry Form - APS Silt Stop Powder may be applied by hand spreader, mechanical disc, or hand
sowing. Slope or ditch application may require artificial support such as straw, or wood fiber
mulch to reduce down slope movement. Areas of high water velocity will require benching or tier
structuring to reduce velocity. Sheet flow applications are best.
APS Silt Stop Powder may be mixed with dry silica sand to aid in spreading. Ratios of sand to
powder will vary in accordance with the type of spreading device used.
Liquid Form - APS Silt Stop Powder may be applied with hydroseeders,'water trucks or other
spraying devices. All spraying devices must have a mechanical agitator or mixing apparatus or
hydraulic recirculation. Caution -Do Not mix powder into a spraying device that does not
contain a mixing apparatus.
Mixing - Sprinkle powder into the water with the mixing apparatus operating as the last material
to be added to the mix. Three to Five minutes of mixing will be required after the powder is
sprinkled into the water. ADD THE POWDER SLOWLY -adding the powder to fast will
result in clumping resulting in poor performance.
Longer mixing times will create high viscosity solutions possibly causing some types of
spray equipment to undergo cavitation.
Caution - Do Not exceed 8 Ibs 1 1500 gallons as viscosity of the water may damage spraying
equipment. (This will treat'/2 acre)
Clean-up
Spilled powder should be cleaned up dry as best as possible using broom or vacuum. Extreme
slippery conditions will result. In event of skin contact, wash power from skin as soon as possible
using soap and water.
Precautions 1 Limitations
• Prevent inhalation of the powder, use adequate dust mask.
• Clean up spills quickly. Do not use water unless necessary, extremely slippery conditions will
result.
• Do Not add water to the APS Silt Stop Powder, add the powder (sprinkle) to the water slowly.
• APS Silt Stop Powder will remain viable on the soil surface for 60-90 days. Longer viability
will occur when applied powder is covered with straw or wood fiber mulch.
• APS 700 Series Silt Stop powders have been specifically tailored to specific soil types. Soil
types in varying geographical areas may require testing, If proper performance of this
product is not satisfactory, contact Applied Polymer Systems.

RE: South Wake Landfill
Wake County, North Carolina
Stormwater Control Permit NCG120080
Dear Mr. Smith:
Zt

On behalf of Wake County North Carolina, South Wake Landfill, LLC, Wake County North Carolina has
proposed modifications (copy attached) to the Sedimentation and Erosion Control Plan for the South
Wake Landfill located at 6000 Old Smithfield Road in Holly Springs, North Carolina. The landfill is
operating under coverage from two NPDES permits: NCG0100 (issued by the Division of Land
Resources) and NCG120080 (issued by the Division of Water Quality).
As described in the "Stormwater Management Plan for the South Wake Landfill (prepared by Oiver Inc.,
Charlotte, N.C., March 2007), the landfill is expected to have a life of 25 years. After the landfill reaches
final capacity, the final cover system constructed and the associated stormwater control devices installed,
then the erosion control measures will be converted into permanent Stormwater control measures. Due to
the long-term construction of the landfill, coordination between erosion control and final stormwater
management is critical.
The proposed modifications are intended to incorporate state of practice sedimentation control features
into operations at the landfill. The modifications are intended to enhance the efficiency of the existing
sedimentation and erosion control features and do not affect the requirements or long-term design
features of the Stormwater Plan. Upon final closure of the landfill, the structures and BMPs prescribed by
the Stormwater Plan will be implemented.
Based on the conditions of the Permit and conversations with the DWQ Stormwater Permitting Unit, we
do not believe that any action is required by the DWQ on this matter. However, we believe that DWQ
should be notified. If you require additional information or wish to comment, please feel free to contact
me at 919-828-0577, or email at gregm@rsgengineers.com.

RE: Erosion & Sedimentation Control Enhancements
South Wake MSW Landfill
Wake County
Original Approval March 14, 2007
Dear Mr. Holley:
The proposed modifications described in this document are submitted on behalf of
Wake County Disposal, LLC (WCD), the operator of the South Wake MSW Landfill
located at 6000 Old Smithfield Road in Holly Springs, North Carolina. WCD seeks to
enhance the performance of selected sediment and erosion control features installed at
the site. The proposed enhancements are intended to incorporate state -of -practice
sedimentation control features into operations at the landfill to assist the operator in
meeting basin discharge turbidity requirements. WCD would like to enhance sediment
collection by using polyacrylamide (PAM), substituting fiber check dams (FCD) for
selected rock check dams, and by enhancing selected temporary and permanent
sediment basins by constructing sediment collection "forebay"' areas within the basins.
In general, the sediment collection forebay areas are planned to collect sediment from
low -flow rain events in a localized area within the basins, and therefore allow easier
cleanout. Adding PAM to the storm water is expected to increase the needed frequency
for sediment basin clean -out, so making clean -out easier is desirable.
On March 14, 2007, the North Carolina Department of Environment and Natural
Resources Division of Land Resources (DLR) issued a Letter of Approval for the
Sedimentation and Erosion Control Plan for the South Wake Landfil12 prepared by
Olver, Inc. (Charlotte, North Carolina) on behalf of Wake County (the permit holder).
The sediment collection areas referred to in this correspondence as "forebays" are neither intended nor
designed to function as DWo Wet -Pond Vegetated Forebays.
2 When DLR issued the Letter of Approval, -they required six modifications to the Sediment and Erosion
Control Plan for the South Wake Landfill. These modifications were included in the revised plan issued
by Olver, Inc. dated April 2007.

The site was granted coverage under the General Stormwater NPDES Permit
NCG010000. The Wake County government has reviewed and approved the proposed
enhancements in a letter dated June 91h (attached). WCD requests that the following
enhancements be accepted as modifications to the current plan:
1. Polymer Addition to Stormwater. PAM will be introduced to the stormwater
runoff in accordance with the manufacturer's instructions and Section 6.8.2 of the
most recent version of the North Carolina Erosion and Sediment Control
Planning and Design Manual. The specific polymer will be determined based on
the most effective performance during bench tests. PAM is proposed to be
placed:
❖ on coir wattles to be installed across channels (as fiber check dams);
❖ on selected slopes, either by broadcasting over existing vegetation, or by
adding PAM to organic erosion control blankets or similar, manufactured
materials; and
As floc -logs at the drop inlets and/or culverts that flow directly into the
basins.
In general, PAM will be added as far upstream from the discharge point as
practical to allow the maximum time for blending with the storm water. The exact
locations of PAM addition will be determined based on the effectiveness of the
treatment in reducing suspended sediments, but the initially planned application
areas are shown on Figure 1. The specific PAM chosen for the site will depend
on the outcome of bench tests to determine the effectiveness of various
polymers. Preliminary tests indicate significant turbidity reductions with PAM
products marketed by Applied Polymer Systems as 712 (powder) and 705
(granular), although the specific product used may depending on effectiveness,
availability or cost. Similarly, the exact application quantity will be determined in
the field, based on observed results. The soil types subjected to runoff may
change, due to different soils present in new (previously approved) areas of
disturbance, or due to different soil types in stockpiles of soil brought in from off -
site. If stockpiled soil types differ from those initially tested, alternative PAM
products may be used from time to time.
2. Add a Sediment Collection Forebay to Sediment Pond No. 1. To prevent
sediments from accumulating across the entire (approximately 9 acre) sediment
pond, a forebay structure is proposed for (permanent) Sediment Pond No, 1.
The forebay will be constructed in the southeast portion of Sediment Pond No. 1
(Figure 3). The forebay will be approximately 250 long and 60 feet wide, in the
location shown on Figure 4. The forebay will be formed by constructing an
embankment within the existing limits of Sediment Pond No. 1. The top of the
forebay embankment will be at Elevation 281.4 feet, which is 1-foot lower than
the top of the embankment around Sediment Pond No. 1. An approximate
section of the sediment collection forebay embankment is shown on Figure 5. A
25-foot wide spillway at Elevation 279 feet will pass flow from the forebay to the
John Holley
June 9, 2009
Page 3
primary pond. Calculations for the forebay (attached) route both the 10-year and
25-year storm events through the forebay.
3. Modifications to Temporary Sediment Basin A (Stormwater Permit Outfall
No. 5). Plunge pool/sediment collection forebay areas (Figure 6) will be
constructed at both inflow locations to Basin A to allow sediment to be collected
before reaching the skimmer or emergency spillway. Porous baffles will be
installed at the plunge pool/sediment collection forebay areas to encourage
sediment collection (Figure 6). The areas will be approximately 1,000 square
feet and 2 feet deep. Constructing the sediment collection forebays will allow
equipment easier access to the basin for sediment removal, facilitate clean -out
and enhance the performance of the basin. The location of porous baffles will be
modified to promote sediment accumulation in the sediment coliection forebays.
The forebays will add a slight increase in storage capacity of the temporary
sediment basin, but not sufficient to affect the hydraulic performance of the basin.
4. Excavating a Sediment Collection Forebay for Sediment Pond No. 2. The
southern end of permanent Sediment Basin No. 2 (Figure 7) will be excavated
by as much as 4 feet (to approximately Elevation 302 feet), and an embankment
will be constructed to create a forebay/sediment collection area within the
existing basin. The embankment creating the sediment collection forebay (at
elevation 304) is approximately 3-feet lower than the principal spillway (Elevation
307 feet). The excavation will yield approximately 240 CY of soil, of which
approximately 140 CY will be used for the embankment. Therefore, constructing
the forebay will expand the capacity of the basin by approximately 100 CY (or
approximately 2500 cubic feet of additional storage capacity). The existing 24"
diameter culvert into the basin will be relocated (also shown on Figure 7) so that
flow will enter the basin through the forebay. The forebay is expected to
decrease any turbidity in.the discharge from the basin and create an easier
location for sediment clean -out.
5. Construct a Sediment Collection Forebay in Sediment Basin B. To contain
sediment in a localized area, a low dike will be constructed across temporary
Sediment Basin B (Figure 8), creating an area approximately 60 feet long by 30
feet wide and 1-foot deep for sediment collection. The top of the dike will be at
Elevation 284 feet, approximately 2 feet lower than the perimeter berm for
Sediment Basin B. A 10-foot wide vegetated spillway (Figure 9) will allow
discharge from the sediment collection forebay into the sediment basin. The soil
used for the berm to create the sediment collection forebay will consume some of
the available storage volume in the sediment basin; however, the capacity of the
sediment basin is approximately 5 times greater than required for the
(approximately 1-acre) drainage area. Routing calculations for the basin and
forebay are attached.
John Holley

6. Substitute Fiber Check Dams (FCD) for Rock Check Dams. Recent studies3
indicate that FCDs can be more effective at removing sediment than rock check
dams. WCD is planning to use FCDs on a trial basis to determine their
effectiveness at this site. FCDs will be installed across channels so that the top
of a downstream check dam will be at the same elevation as the base of the
adjacent upstream channel. At this time, WCD does not plan to replace all
existing rock check dams with FCDs, but would like the option to use FCDs in
future construction and/or maintenance. Initially, FCDs will be installed in
Channel DC -A (east of the landfill, draining to Sediment Basin A).
We appreciate your prompt attention to this request for modification. If you have any
questions regarding these proposed modifications, please do not hesitate to contact
David Pepper of Waste Industries USA, Inc. or Greg Mills, P.E. of Richardson Smith

Subject: Request for Representative Outfall Status.
South Wake Landfill
Stormwater Permit NCG120080
Wake County
Dear Mr, Smith:
On October 6, 2008 Raleigh Regional Office (RRO) representative Judy Garrett observed the
mine site with you to evaluate your request for representative outfall status. During that
inspection the possibility of Representative Outfall Status was discussed.
You requested that outfall No. 1 be allowed to represent the remaining10 outfalls represented on
the map you submitted with your request, titled Representative Outfall Plan, Wake County
DisposaltLLC;-South Wake MSW Landfill, Phase I NPDES Monitoring Plan, Fig. 1.
jl s -During-the review of the existing data it was noted that no analytical data has been analysed for
any of the outfalls. Existing qualitative reports indicate orange color in many locations. It was
noted that.the qualitative monitoring was conducted on the uphill side of the outfalls. The
qualitafive:non' itortng should be conducted at the end of each outfail(effluent side).'
It is determined that the following outfalls can be representative of other outfalls at this time:
1) Outfalls 1 and 5 must continue to be monitored as required and may be allowed to be
representative of outfalls 2, 3 and 4. The effluent of outfall 1 could not be located
due to flooding caused by a beaver dam. The flooding will have to be eliminated so
that qualitative and analytical monitoring can be conducted at this outfall.
2) Outfall number 9 must continue to be monitored and may be considered
representative of outfalls 6, 7, 8, 10 and 11. Outfall 9 pond had a muddy bottom and
the creek was muddy at the effluent.
Sampling is required at the frequency and for the parameters set forth in the permit for Outfalls
1, 5 and 9.
Because topography and activities change in a dynamic landfill situation, the above approval of
the representative outfall may be revisited/re-opened by either Division of Water Quality or
Wake County. Also, if new outfalls are added or if outfall locations are changed, sampling is
required. In addition, after analytical data is obtained from these locations, we may revisit the
request for representative outfall status.

required. In addition, after analytical data is obtained from these locations, we may revisit the
request for representative outfall status.
Please note that the representative outfall designation is only for analytical monitoring
requirements of the General Stormwater Permit. The qualitative monitoring requirements are
still effective for all stormwater outfalls.
All sedimentation and erosion controls must be maintained as required by the sedimentation and
erosion control plan approved by the Division of Land Resoureces. In addition, the facility must
comply with the landfill permit issued by the Division of Waste Management.

Representative Outfall Status Petition (NCG #120080)
Dear Ms. Sullins,
On behalf of Wake County, Richardson Smith Gardner & Associates, Inc. is submitting this
petition for representative outfall status as described in Part III, Section D of the permit
guidelines for Stormwater General Permit NCG120000.
Industrial Activities
Wake County's (MSWLF) Landfill will receive municipal solid waste (MSW) originating from
residential, commercial, and industrial sources as permitted under NC Solid Waste Permit No.
92-22. Stormwater runoff associated with the development of the site has been delineated by
drainage area as shown on Figure I (attached) and summarized by outfall watershed area in
Table 1. Currently, there are I 1 outfall points for the Phase 1 A operations which warrant a
"representative outfall".

Potential Pollutant Exposure
The South Wake Landfill potential pollutants are (1) the active landfill, (2) vehicular traffic, and
(3) the leachate storage tank area. The active landfill is the primary potential pollutant area as
defined by the general permit. The leachate storage tank area functions to collect stormwater
that comes into contact with waste prior to discharge to the Town of Holly Springs POTW
(Publicly Owned Treatment Works). This storage area includes glass -fused to steel bolted tanks
inside a secondary containment. Lastly, vehicle traffic associated with waste disposal,
operations, and maintenance are transient across the site. However, the predominant exposure
would include operational equipment which is maintained within the active landfill area. As
shown in Figure 1, the proposed Outfall No. 1 represents a conservative point for monitoring
since it includes all three (3) potential pollutant exposure activities.
Proposed Representative Outfall
Outfall No. I represents the largest drainage area with the highest potential pollutant exposoure
originating from the site. Approximately 41 acres drain into Sediment Basin No. 1 located on
the southwest corner of the site. The remaining outfall areas are substantially similar to one
another in terms of size and potential pollutant exposure.
We appreciate your attention in this matter and are prepared to promptly respond to any
questions or concerns regarding this request. Should you have any questions or require
clarificaiion, please contact us at (919) 828-OS77 or by email below.
