Dear Mr. Pickle:
This letter is to satisfy the request from DEMLR that the Foxhole Landfill plan and implement additional BMPs
to improve stormwater quality. The dry detention Basin 6 is the target for stormwater improvement. These
BMPS are designed to reduce the TSS that is discharging from Basin 6 in excess of the benchmark value in the
permit. The following table is a list of actions to be taken and the time frame.

The items in the table above will be completed over a 6 month time period. The weather will determine the
actual schedule. Compliance storm water samples will be collected for TSS after completion for the BMWs and
for a period of at least 3 months following completion to measure effectiveness. If the measures in the table
above are not effective in reducing TSS to below permit benchmark values, a second round of BMPs will be
implemented. These BMPs may include changing the setup of the baffles, installing a Faircloth skimmer or
terracing or reworking the slope.

1.0 Introduction
The Mecklenburg County Foxhole Landfill is owned and operated by Mecklenburg County. The
facility is located at 17131 Lancaster Highway in Charlotte, North Carolina and covers
approximately 560 acres. The Foxhole Landfill operates under NPDES Certificate of Coverage
number NCG 120068.
Approximately 1 % of the drainage area is impervious. Stormwater flows across the site into 3
stormwater detention basins. The stormwater outfalls from these basins eventually discharge to
Six Mile Creek. Two large construction projects have changed the stormwater drainage at the
site. The addition of a new landfill cell has removed Basin 4. The areas that previously drained
into Basin 4 now drains into Basin 6, along with the entire new landfill cell. The expansion of the
recycling center has removed Basin 1. Drop inlets were installed and the stormwater is now
piped to the ditch that drains to Basin 3.
2.0 Sample Information
Laboratory samples were collected at the 3 stormwater basin outfalls in accordance with the
NPDES permit by Amber Grzymski. The samples were analyzed by Charlotte Water Laboratory.
The tables below summarize the sample results for the duration of the current permit.
Highlighted results are over the benchmark values.

3.0 Stormv►ater Inspection
A stormwater inspection of the 3 basins that exceeded one or more benchmark values was
conducted on May 10, 2013 by Amber Grzymski, Project Manager and Terry McCarver, Landfill
Manager. The drainage area to each of the impacted outfalls was examined as well as the basin
itself. da/.
Basin 2 drainage area includes the y�dwaste'�process�ingaQThe size of the impervious surface
in this area has doubled in 2013. The end of the asphalt pad is now much closer to the
stormwater basin and runoff from yard waste reaches the basin much quicker than previously.
Increased runoff from larger amounts of yard waste could be contributing to the high fecal
coliform results at Basin 2.
Basin 3 receives discharges from the stormwater ditch that goes around one side of the landfill
and from the recycling center (previously discharged into Basin 1). The ditch was well grassed
and the basin looked really good. No erosion was noted, but small amount of silt was noted in the
ditch from the ongoing construction of the recycling center. No obvious source of fecal coliform
was noted. Abundant wildlife has been noted in theareaof Basin 3.
Basin 6 receives the discharge from a stormwater ditch that goes around the other side of the
landfill, including the new landfill cell. The new portion of the ditch around the new landfill cell
has ground cover established and has stabilized. The ditches and Basin 6 looked good with no
erosion problems noted. Basin 6 is in a remote area of the site, bordered by a conservation
easement. Wildlife is frequently in the Basin and the surrounding area. No other sources of Fecal
Coliform were noted.
A stormwater inspection of the 3 basins that exceeded one or more benchmark values was
conducted on January 9, 2014 by Amber Grzymski, Project Manager and Steve Currie, Landfill
Operator (Currently, Landfill Manager). The drainage area to each of the impacted outfalls was
examined as well as the basin itself.
Basin 2 drainage area includes the yard waste processing area. Increased runoff from larger
amounts of yard waste could be contributing to the high fecal coliform results at Basin 2.
As a result of the Tier One response, compost filled socks were installed along the edge of the
yard waste pad in June 2013 to catch some of the yard waste fines and treat fecal coliform. A
compliance sample of Basin 2 in July 2013 did not show any reduction in fecal coliform levels.
The socks have since degraded and are no longer effective at trapping fines.
Basin 3 receives discharges from the stormwater ditch that goes around one side of the landfill
and from the recycling center (previously discharged into Basin 1). The ditch was well grassed
and the basin looked really good_ No obvious source of fecal coliform was noted. Abundant
wildlife has been noted in the area of Basin 3.
The Tier One report recommended that a compost sock be installed in the drainage ditch to
reduce fecal coliform. The compost sock that was installed in the area of the ditch that drains to

basin 3 was not effective at reducing fecal coliform based on current sampling.
Basin 6 receives the discharge from a stormwater ditch that goes around the other side of the
landfill, including the new landfill cell_ The new portion of the ditch around the new landfill cell
has ground cover established and has stabilized. The only area of erosion noted was at the corner
of the soil stockpile where the water runs off the pile. A large gully has opened up and needs to
be repaired. Basin 6 is in a remote area of the site, bordered by a conservation easement. Wildlife
is frequently in the Basin and the surrounding area. No other sources of Fecal Coliform were
noted. TSS was elevated in the most recent stormwater sample. This appears to be due to the loss
of the plugs in the riser pipe in the basin.
4.0 Selected Actions
The following actions were taken as part of the Tier One and Tier Two requirements of the
NPDES permits.
Basin 2 — A compost sock border will be placed along the edge of the yard waste pad that drains
to Basin 2. Compost socks will also be placed in the stormwater ditch that leads to Basin 2.
Basin 3 —One compost sock will be placed in the stormwater ditch just prior to entering Basin 3.
Basin 6 — Rock will be continued to be replaced in large stormwater ditch that leads to Basin 6.
The grass cover is newly established and will continue to improve over the next few months.
The above items were completed in June 2013. The following items were completed by the end
of February 2014.
Basin 2 — A forebay will be created where the two ditches around the edge of the yard waste pad
join together. A large check dam will be placed to slow the release of water from the forebay and
to catch some additional fines.
Basin 3 — Baffles will be placed in the basin to catch some additional sediment. The check dams
in the drainage ditch will be replaced and the rock around the basin riser will be replaced.
Basin 6 — The plugs that belong in the riser pipe will be replaced. Area of erosion at corner of
soil stock pile will be fixed to reduce run off.
5.0 Conclusions
This report outlines the actions taken to improve the stormwater runoff from the Foxhole
Landfill. Monthly sampling has shown a seasonal influence in fecal eoliform bacteria and no
direct link to any BMPs to improve the results_ TSS has increased over time at the landfill due to
increased earth moving activities in two areas that drain to Basin 2 and Basin 6. The actions
taken have reduced the TSS in Basin 2 but have so far been unsuccessful in Basin 6.
Mecklenburg County requested assistance from a consultant to evaluate the causes of the TSS in
2

Basin 6. That report is attached. We have tried to establish cover on the slopes of the basin, but
have not been successful. We do not intend to convert the basin to a wet pond at this time, as the
consultant recommends.
Mecklenburg County Solid Waste requests a variance from the monthly sampling requirement in
the NPDES permit. We will continue to implement common sense BMPs and work with DEQ to
improve stormwater quality at the site. We can collect samples to check the effectiveness of
implemented BMPs if requested. Please consider our request and let us know if any additional
information is needed.

Memorandum
To: Mecklenburg County, NC
From: CDM Smith
Date: May 8, 2015
Subject: Technical Memorandum
Mecklenburg County Foxhole Landfill Facility Sediment Pond #6 Issues
Mecklenburg County, North Carolina
CDM Smith Project No. 133880-107604
1. Purpose
The purpose of this technical memorandum is to define several ongoing stormwater issues with
respect to the overall lack of vegetation and the resulting erosion and sedimentation that are
effecting the operation of the Foxhole Landfill Facility in Mecklenburg County, North Carolina
(County).
2. Project Information
General
The Foxhole Landfill, located in Mecklenburg
County at 17131 Lancaster Highway, Charlotte,
NC (see Figure 1) is currently under NPDES
regulatory monitoring requirements -for
u7=Stormwater Ponds #2 and #6 with respect tootal Suspended Solid (TSS)es.
The landfill is currently operating under Tier 3
yes 6�f a%so status for these two ponds, which is triggered
by four or more exceedances over the
allowable limit; this requires notification of the
North Carolina Division of Energy, Mineral and
Land Resources (DEMLR), who may then revise
the monitoring requirements and require
additional Best management Practices (BMPs).
Figure 1: Location map
Pmd6m&"0 5-&I&dm

Mecklenburg County Foxhole Landfill Facility Sediment Pond #6 Issues
May 8, 2015
Page 2
Recent site monitoring demonstrates that Pond #2 is no longer experiencing high TSS levels, but
Pond #6 continues to exceed allowable levels (see sampling results in Appendix A). Field
investigations of Sediment Pond #6 show un-vegetated areas with steep slopes that are
experiencing severe erosion and are directly connected to the pond, as shown on Figure 2. The
pond bottom itself is also lacking in vegetation, further contributing to the erosion issues and the
discharge of turbid water.

3. Slope Stability
Slopes throughout the sediment pond should be vegetated with a fast growing ground cover over
the non -vegetated areas. Slopes experiencing the most severe erosion should be terraced or graded
to a maximum slope of 4HAV where practical to reduce runoff velocities.
4. Drawdown Analysis
To determine the underlying cause of the lack of vegetation in Sediment Pond #6 a stormwater
routing simulation was performed to determine system recovery time. Per the North Carolina
Department of Natural Resources (NCDENR) Stormwater BMP Manual, dry detention basins shall
PeM14Mrno„iE-udoo

Mecklenburg County Foxhole Landfill Facility Sediment Pond #6 Issues
May 8, 2015
Page 3
detain the applicable design storm for no less than 2 days but no more than 5 days to allow
sufficient time for settling while not drowning existing vegetation.
The Chainsaw Routing method was used to evaluate Pond #6 as specified by the NCDENR
Stormwater BMP Manual. The Chainsaw method, developed by H. Rooney Malcom, PhD, P.E. of
North Carolina State University, is appropriate for the design of small systems, and relies on three
sets of source data:
1) System inflow hydrograph;
2) The size and shape of the storage basin; and
3) The hydraulic configuration of the stormwater control device.
The routing analysis was performed for a dry basin, routing a 1-year, 24-hour design storm (3.5
inches of rain over 24 hours). A smaller design storm was analyzed as it occurs more often and is
representative of normal operating conditions. For peak stage and flow analyses a larger design
storm is evaluated, such as the 25-year, 24-hour storm for pre- versus post -conditions peak
discharges. It can be seen on Figure 3 that with the current pond control configuration there is an
extended drawdown period.

Figure 3: Sediment Pond #6 Inflow and Outflow
It should be noted that the pond 6 storage configuration was estimated using Google Earth along
with limited design information from the 2004 Withers & Ravenel design plans provided by
Mecklenburg County.
The bleed down configuration of the pond control structure was simplified for the analysis. All 40 of
the 2-inch perforations in the pipe were evaluated at elevation 578.5 rather than in 4 staggered
rows of 10. This simplification acts to increase the recovery capacity of the facility, as it applies
increased driving head to the perforations. Even with the increased hydraulic recovery capacity, the
evaluation shows an extended recovery period in excess of 40 days as shown on Figure 3. The
detailed Chainsaw routing information is contained in Appendix B.
Infiltration into the pond bottom is inappreciably low based on an analysis of the available boring
information. The borings previously obtained in Sediment Pond #6 revealed an infiltration rate of
3.4x10-6 cm/sec [0.0048 in/hr = 0.01 ft/day] as shown in Appendix C, Boring B-22A. This
infiltration value is extremely low, and based on other nearby borings the soils near the ground
surface appear to he elastic silt. The elastic silt has even slower rates of infiltration than what was
PaM0Acno "-iiem

Mecklenburg County Foxhole Landfill Facility Sediment Pond #6 Issues
May 8, 2015

shown at B-22A. To get recovery for retention systems, infiltration capacities in excess of 0.5 ft/day
are typically required, meaning that the major recovery occurring within Pond #6 is via the
perforations in the riser and evaporation.
5. Improvement Alternatives
To reduce TSS to allowable levels it is necessary to reduce the TSS concentration in the inflow by I iQ
stabilizing exposed areas within the contributory area and by stabilizing the pond bottom itself. For �D
each alternative presented under this discussion, the following steps are considered initial actions
that should be implemented:
• The exposed hill that is immediately up gradient of the facility needs to be regraded and (D
vegetated as soon as possible.
If the existing control structure configuration utilizing orifices is maintained then filter
fabric should be installed over the control structure orifices (perforations) and replaced
annually. Double layer nonwoven fabric should be used as it provides the highest filtration
efficiency.
Two alternative options have been developed to address the ongoing erosion issues and associated
elevated TSS levels and the lack of vegetation in Sediment Pond #6. Both alternatives are geared at
reducing the amount of additional turbidity generated when stormwater runoff inflows to the
facility flow across the exposed pond bottom, mobilizing sediment and increasing TSS levels.
1) Re -design the existing control structure to provide for a recovery time within the 2 to 5 day Q
period as specified by NCDENR. Recovery periods in excess of 5 days typically result in
vegetative mortality.
2) Re -design the pond to function as a wet pond. The upside of this option is that it would
generate fill for the landfill and remove the issue of vegetating the bottom; only the side ;
slopes and contributory areas would need to be addressed.
In redesigning the existing control structure, downstream discharge limitations would need to be
considered. Additionally, in conjunction with this option it would be beneficial to scarify the pond JQ
bottom to increase infiltration capacity, regrade slopes to a maximum of 4H:1V, and plant it with a `
fast growing vegetation capable of being periodically inundated to stabilize the soil.
If the facility is re -designed as a wet pond, the downstream discharge limitations would still need to
be considered. In converting the facility to a wet pond the issue of re -vegetation shifts to the facility
side slopes. Additionally, a wet pond would require a re -design of the facility control structure.
Both options will require additional analysis and design, along with meetings with the regulators to
confirm that the proposed change is acceptable and within the regulatory requirements for the site.

Mecklenburg County Foxhole Landfill Facility Sediment Pond #6 Issues
May 8, 2015
Page 6
6. Recommendations
The following recommendations are made:
Terrace or regrade compromised slopes to a minimum of 4HAV.
• Vegetate all slopes (hydroseed or equivalent) and the pond bottom - it is recommended that
the County vegetate all exposed areas with a fast growing cover crop capable of stabilizing
the soil. Silt fence should be installed along the bottom of the eroded slope immediately
north of Sediment Pond #6 that is contributing sediment to the facility (see Figure 2).
Pond bottom - use a combination of native wetland plants for either a current dry or
excavated wet alternative (perimeter around the inlet of at least 25 ft - there can be a
maintained internal annular ring of 5 to 10 ft to keep the standpipe clear).
To address the ongoing erosion issues and associated elevated TSS levels in Sediment Pond #6, it is
recommended that the County move forward with converting the existing dry facility into a wet
detention pond. The soil that is excavated from the facility can be used on -site for landfill cover,
which will act to offset the cost of converting the facility.
The initial capital investment associated with converting the facility to a wet pond is greater than
re -designing the control structure, but it will provide a better long-term solution while addressing
the immediate need of reducing the discharge of turbid water from the site.

Task: Sediment Pond 6
Checked BY: S. Nehrke
OBJECTIVE
Perform a routing of the Sedimentation Pond 6 to evaluate performance
BACKGROUND
1.) Use the Chainsaw Routing Method, as outlined by HR Malcom, PE, Ph.D, NCSU
2.) The Department of Environment and Natural Resources (NC DENR) Erosion and Sedimentation
Control Planning and Design Manual requires the following for Pond #6
a.) The pond must safely pass the 10-yr, 24-hr design storm event with a minimum one (1)
foot freeboard
b.) The sediment basin shall settle the 40-micron particle with a minum efficiency of at least
70 % during the 2-yr peak runoff event
3.) The original design parameters were obtained from the W&R Subtitle D Landfill Engineering Plans -
November 2004
4.) Use the precipitation data for Meclenburg County.
DEVELOPMENT
1.) Drainage area, pond, and spillway characteristics
Drainage Area (acres) = N/A Riser Diam (in) = 72
Time of Concentration (min) = N/A Riser Elev (ft) = 588,5
Pond Invert (ft) = 578.5 Barrel Diam (in) = 36
Pond Crest (ft) = 592.2 Barrel Elev (ft) = 578.5
Drawdown Perforation Diameter (in) 2
Number of perforations per Row 10
Number of rows 4
Drawdown Elevs (ft) = 578.5, 579, 579.5, 580
Drawdown Configuration based on 2004 plans by Withers & Ravenel
2.) Stage/Storage estimated from Google Earth and limited design drawing info.
RESULTS
Based on the results of the chainsaw routing, the following parameters were identified.
Peak Discharge (cfs) =
3.8
Peak Stage (ft) =
579.4
Freeboard (ft) =
12.8
Min Settling Efficiency =

Subject: Foxhole Landfill relief from monthly monitoring, NCG120068
Hi Amber,
Please consider this email as DEMLR's notification that Mecklenburg County can revert to semi-annual monitoring of
stormwater discharges for the remainder of the current term of Certificate of Coverage NCG120068. As provided for
in the Tier 3 portion of General Permit NCGI2DODo, DEMLR hereby releases Mecklenburg County from the Tier 2
requirements for monthly monitoring as a result of the past benchmark exceedances for fecal coliform, TSS, and COD
at Outfalls 2, 3, and 6.
In addition to my review of your January 27, 2016 request to discontinue monthly sampling, we have exchanged email
communications and engaged in phone conversations on the conditions at the Foxhole Landfill, a C&D landfill with a co -
located yard waste grinding operation. Our agreement with your request is based on those communications, and our
conclusions and directions are as follows:
• Although monitoring results are still exceeding the benchmark values, we concur that continued monthly
sampling does not appear to promise to lead to more effective control responses.
• We note that the facility has indeed already tried several response measures and has sought evaluation and
recommendations from environmental consultants to improve pollutant control performance. Further, I
understood from our discussions that it's not fully clear to Mecklenburg County what to try next.
• We caution that by granting relief from monthly monitoring DEMLR does not invalidate the benchmark values as
performance targets, nor do we stay any other permit conditions. We expect Mecklenburg County to continue
with additional efforts to improve control of the stormwater pollutant parameters.
• Please deliver to the Stormwater Permitting Program in the Raleigh Central Office, with a copy to the DEMLR
Mooresville Regional Office, a brief written plan and schedule for the next response action to the benchmark
exceedances. We discussed the perspective that it's not fully clear what might be done next. We also discussed
that the next steps need not be comprehensive, or could be phased in based on accumulating successes or
failures of successive attempts at improved control. We discussed whether the next step might focus on just
Outfall 2 (draining the yard waste grinding operation with the highest fecal and COD exceedances) or just Outfall
6 (highest TSS discharges), or try some other phased, incremental approach to improved control. Please deliver
your written plan and schedule on or before June 30, 2016.
Please contact me with any follow-up discussion.
Best regards,
Ken

Subject: RE: Foxhole Landfill NPDES # NCG120068
Hi Amber,
Are you available to again discuss by phone the circumstances at Foxhole landfill? If so, I'm available tomorrow
afternoon, and early Friday morning (8 —10), and completely open every day next week.
I've been through your January 27, 2016 letter and report requesting relief from monthly sampling, as well as the
attached consultant's Technical Memo on Basin 6, dated May 8, 2015. I've also looked back through our files here in the
Central Office. I apologize for my delay in responding.
I think there is some merit in the observation that continued monthly sampling is not going to reduce the discharge of
pollutants at Foxhole, and that relief from monthly sampling is therefore appropriate. However, I'd like to get to the
point of granting relief after more discussion with Mecklenburg County about whether there may be feasible cost
effective options still remaining and worth trying out. Let me know when we can discuss that, please.
Best regards,
Ken
Background on my review and perspective so far:
Here's what I think I see from my review so far. (Amber, 1 am open to correction on the facts and contradiction on the
interpretations: I haven't been to the site, and you have, obviously. I'm going through my first -review perspective below
specifically to provide a more detailed basis for our phone discussion.):
• it seems that you are dealing with a difficult set of circumstances, and a cheap solution may not be immediately
evident. You have already tried several measures within the Tiered response structure of the General Permit.
1 note that TSS and fecal exceedances have been present since the earliest inspection by our Mooresville staff in
2007 (original permit coverage issued in June 2003), and have continued to be present up through sampling
results reported from November 2015.
I found the January 12, 2010, waiver letter from the DWQ Mooresville Regional Office granting relief from the
Tier 2 monthly monitoring requirement. Our past procedure has been to specifically identify the waiver period
in the Tier 2 waiver letters. Unfortunately, the MRO letter does not tie down the waiver period. In this case my
interpretation would be that the 2010 waiver should be interpreted to last for the duration of the then -current
permit cycle. In 2010 the effective permit cycle was from November 1, 2007 until October 31, 2012. It's my
interpretation that the 2010 waiver has lapsed along with the outdated General Permit; the new re -issued
General Permit NCG120000 pertains; and that you are correct in re -applying for a waiver at the Foxhole landfill
under the currently effective provisions of the 2012-2017 version of NCG120000.

s
• As to the three current outfalls:
o Outfall #2: 1 share your suspicion that the yard waste processing area may be the cause of fecal being so
much higher at Outfall #2 than at Outfalls #3 and #6. (Outfall #2 had 8 out of 17 fecal measurements
with greater than 500,000 count vs. 32 measurements not greater than even 100,000 count at the other
two outfalls combined.) I note the last four monthly measurements for fecal were >600,000; >600,000;
510,000; and >600,000 counts vs. a stormwater benchmark of 1000 count. Those are pretty high
numbers, and in my mind seem to subvert a "natural wildlife" interpretation for Outfall #2. Again,
neither of the other two outfalls had even a single measurement over 100,000 count.
■ In June 2013 compost socks were deployed, but soon determined to be ineffective, and
subsequently abandoned for either fecal or TSS control.
• In February 2014 a rock check dam and a forebay were installed on the drainage system
feeding Basin 2. No subsequent reduction in fecal is reflected in the data, as far as I can tell.
■ Tiers 2 and 3 are triggered at Outfall #2.
■ The TSS data since January 2015 might be interpreted to show a recent improvement, but it's
not clear why since the improvement does not correspond in time with the installation of the
check dam and forebay measures. Additional good results would be necessary to conclude that
Mecklenburg County has indeed successfully addressed the TSS at Outfall #2. Similarly for the
COD data which has exceeded the benchmark value in 50% of the measurements.
o Outfall #3: Continuing benchmark exceedances on fecal. Only sporadic exceedances on TSS.
• In June 2013 a compost sock was deployed in the drainage ditch, but was soon determined to
be ineffective in reducing fecal.
■ In February 2014 baffles (erosion control fabric?) were placed in the basin, the stone check
dams were replaced, and the rock around the basin riser outlet was replaced. Again, it's not
clear that these measures reduced either fecal or TSS. I note that the four TSS exceedances
occurred after the deployment of the tiered response measures.
■ COD performance has been consistently within the benchmark. KHP Personal opinion: In
comparing Outfall #3 to Outfull #2, again l suspect the fully exposed yard waste area as a
potential source not only of the much higher fecals in Outfall #2, but also the consistently higher
COD values.
■ Tiers 2 and 3 are triggered at Outfall #3.
o Outfall #6: Fecal and TSS both consistently over the benchmark values. Single exceedances of COD and
O&G (out of 16 measurements) can be ignored for now. If Mecklenburg County successfully addresses
the other two pollutants, we can hope that these measurements could be subsequently interpreted as
one-time flukes.
• In June 2013 rock was placed in the drainage system to the basin (check dams? erosion
armoring?), and a new grass cover was being established.
■ In February 2014 plugs in the riser pipe were replaced (to slow the discharge rate?) and the
nearby soil stockpile was stabilized to prevent transport to Basin #6 and subsequent
discharge. It is not clear from the data that these measures produced reductions in the
stormwater discharge for either fecal or TSS_
• Attempts to stabilize the side slopes of Basin #6 with vegetation have not been successful.
■ The consultant's Technical Memorandum dated May 8, 2015 contains a menu of potential
response measures to address benchmark exceedances:
• Side -slopes for Basin #6 should be re -graded to 4:1 and vegetated to control erosion,
which is presumed to be contributing to the discharge TSS.
• An adjacent hill should be re -graded and stabilized with vegetation.
• Other exposed portions of the contributing drainage area should be stabilized.
• Fabric covering of the orifices on the existing outlet structure should be installed;
• Or alternatively, re -work the existing outlet structure to decrease the time that runoff is
detained in the basin so that vegetation can thrive on the basin floor;

L
• Or alternatively, re -design the basin to function as a wet detention basin instead of a
dry -detention basin, including a re -designed outlet structure.
• Selective installation of silt fence in specific areas of the contributing drainage area.
■ Tiers 2 and 3 are triggered at Outfall #6.
o Very short summary: In various places since 2013 Mecklenburg County has added stone or riprap,
attempted stabilization with vegetation, deployed compost socks, constructed a forebay, employed
fabric baffles, and added plugs to one (?) riser structure. In general, and while open to some
interpretation perhaps, results so far have not been encouraging.

Thanks, Amber,
OK, how about 10:00 tomorrow morning? I'll call your cell.
As you indicated in your initial email to Zahid, I think one end point of our call tomorrow will be that I will ask for more
specific information in support of the request to be relieved from monthly monitoring. But it always seems to help to
speak voice -to -voice so 1 can understand better what you have attempted in response to the Tiered structure of the

Let me know if you would prefer a more convenient time tomorrow.

Subject: Tier 2 Monitoring Waiver Response
The Foxhole
COC No. NCG 120068
Mecklenburg County, North Carolina
Dear Mr. Hack:
The Mooresville Regional Office is in receipt of your letter dated December 7, 2009 requesting a waiver for the
Tier 2 Monitoring associated with your stormwater permit. As noted in the last inspection letter, the facility has
implemented several strategies to try and alleviate the benchmark exceedances_ Sampling data has been reviewed
by the Mooresville Regional Office. Some progress has been made and the sample results are, in, general, closer to
benchmark levels. The Foxhole should continue to implement best management practices to strive for permit
compliance; however, at this time the Division concurs that the exceedances are naturally occurring. Additional
monthly sampling would be ineffective and cost prohibitive during these challenging economic times. Therefore
the Division grants The Foxhole a waiver of additional monthly sampling associated with the Tier 2.response of the
site's stormwater permit (NCG 120068). Please be advised that semiannual sampling must still be conducted as
described in Section B Analytical Monitoring Requirements of the permit, but no additional tiered responses will be
required. Please place this letter with your stormwater pollution prevention plan as documentation for the waiver of
the tiered response,
Sincerely,

The Foxhole has performed all sampling as required by the permit. After exceeding
several benchmark concentrations on 04.28.2008, a Tier One response was implemented
in a timely manner. The Tier One response involved removing excess sediment from all
basins and adding filter stone at various locales to slow stormwater flow. The second
sampling event was performed on 11.14.2008. Sample results showed significant
improvement on fecal coliform (FC) at Outfalls 1, 2, and 3. Improvement was also seen
in Outfalls 2 and 3 for Total Suspended Solids (TSS). However, all improved results
were still above the benchmark concentrations, placing Outfalls 1, 2, 3, and 4 into Tier 2
tn sampling. Outfall 5 is under Tier 1 for fecal coIiforand TSS.
All outfalls were observed during the site inspection. The following suggestions were
made with respect to each OutfalI:
1. Outfall 1: To help prevent stormwater from short circuiting the basin, please
install several riprap berms to slow water flow and allow for more detention time.
2. Outfall 2: To help amounts of sediment entering basin, please establish as much
ground cover as possible.
3. Outfall 3: To collect a valid sample, move the sample location from the stream to
the basin riser pipe.
4. Outfall 4: To help prevent stormwater from short-circuiting the basin, reroute
stormwater so that it enters the rear of the basin and not the front near the riser
pipe. Also, collect the sample from basin riser pipe.
5. Outfall 5: Cease all stormwater sampling. This outfall does not enter a
receiving stream, ditch or swale, nor does it leave the property. Flow is dispersed
over —1,900 feet of overland flow nearing a stream. This basin must continue to
be maintained as per the Foxhole's sediment and erosion control plan.
6. Outfall 6: Installed by the facility since last inspection to control an area of
erosion. No sampling necessary, as the outfall provides for overland flow of over
1,900 feet before the nearest receiving stream. This basin must continue to be
maintained as per the Foxhole's sediment and erosion control plan.
The. facility will sample monthly for fecal coliform as per Tier 2 requirements on
Outfalls 1, 2, 3, and 4. Tier 2 sampling for TSS will be performed on Outfalls 2, 3, and 4.
No further sampling is necessary at Outfall 5. No sampling should begin at Outfall 6.
The facility appeared to be well maintained and operated at the time of the inspection.

Compliance Schedule Correction
Mecklenburg
Dear Joe Hack:
It recently came to the Division's attention that the compliance schedule in the NCG120000 permit is
incorrect. The compliance refers to requiring a Stormwater Pollution Prevention Plan which is not a
requirement of this permit. The corrected compliance language that should go under Part III, Section A: 1. is
shown below. We have also attached a new page reflecting this change for your permit file (Part III page 1 of
11). This new page should replace the current page in your permit.
SECTION A: COMPLIANCE AND LIABILITY
1. Compliance Schedule
The permittee shall comply with the permit in accordance with the following schedule:
Existing Facilities: Upon the effective date of the Certificate of Coverage the permittee shall comply
with all of the conditions detailed in Part II, Section A: Final Limitations and Controls for Stormwater
Discharges.
New Facilities: Upon the beginning of discharges from the operation of the industrial activity the
permittee shall comply with all conditions detailed in Part II, Section A: Final Limitations and Controls
for Stormwater Discharges.
If you have any questions concerning this matter please contact Aisha Lau at

Subject. Tier 2 Monitoring Waiver
The Foxhole
COC No. NCG120068
Mecklenburg County, North
Dear Mr. Hack:
Dee Freeman
Secretary
The Mooresville Regional Office is in receipt of your letter dated December 7, 2009 requesting a waiver for the
Tier 2 Monitoring associated with your stormwater permit. As noted in the last inspection letter, the facility has
implemented several strategies to try and alleviate the benchmark exceedances. Sampling data has been reviewed
by the Mooresville Regional Office. Some progress has been made and the sample results are, in general, closer to
benchmark levels. The Foxhole should continue to implement best management practices to strive for permit
compliance; however, at this time the Division concurs that the exceedances are naturally occurring. Additional
monthly sampling would be ineffective and cost prohibitive during these challenging economic times. Therefore
the Division grants The Foxhole a waiver of additional monthly sampling associated with the Tier 2 response of the
site's stormwater permit (NCG120068). Please be advised that semiannual sampling must still be conducted as
described in Section B Analytical Monitoring Requirements of the permit, but no additional tiered responses will be
required. Please place this letter with your stormwater pollution prevention plan as documentation for the waiver of
the tiered response.

Hi Zahid,
Here's my initial email summary to Bethany and Bradley in November about the Foxhole Landfill request for relief from
monthly sampling under Tier 2 and Tier 3. I'll try to follow up this week and copy MRO on any correspondence or

Friends,
Here's a request from Char-Meck's solid waste folks for relief from monthly sampling at the Foxhole Landfill.
I need to get into this to see what makes sense here. Seeking suggestions for an overall approach. Perhaps we can talk
about it next week?
I understand that Zahid forwarded it to us because he doesn't have folks to help with this.
Outfall #002: 15/16 fecals > 1000 count; 8/16 COD> 120 mg/L; 9/16 TSS > 100 mg/L
Outfall #003: 8/16 fecals > 1000 count; 16 COD <120 mg/L; 4/16 TSS > 100 mg/L
Outfall #006: 11/16 fecals > 1000 count; 1/16 COD > 120 mg/L; 14/16 TSS > 100 mg/L
All for samples beginning April 2013 up through 11/2015.
Insufficient explanation offered for what they have attempted, or what they will attempt.
Unsupported assertion that abundant wildlife population is responsible for fecal exceedances.
But, I'm not sure what more testing will show us, until they try something.
Failure to notify us in a timely way of Tier 3 status.

Dear Mr. Khan:
Please find enclosed the stormwater data for the Hwy 521 (Foxhole) Landfill located in Charlotte, North
Carolina. This data covers the current permit cycle. The stormwater BMPs implemented and ground cover
established have improved TSS in Basins 2 & 6. Fecal Coliform continues to be high at all stormwater basins
due to the abundant wildlife at the landfill. We will continue to implement BMPs as necessary to improve the
water quality at the site. Monthly sampling has provided us with a good amount of data to use to continue
improvements. Additional monthly sampling should not be necessary. We will collect additional samples if we
notice any changes or issues on our qualitative monitoring. Mecklenburg County requests that monthly
analytical sampling be discontinued at the Foxhole Landfill.
If you have any questions, please contact me at 704-432-2478 or by email at

COC Number NCG120068
Mecklenburg County
Dear Permittee:
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://aortal.ncdenr.org/web/wg/ws/sulcurrent-
notices), or in the Response to Comments / Summary of Changes and Technical Bulletin documents that are
posted on the Stormwater Permitting Units website with the new General Permit. Please visit
http://Portal.ncdenr.org/web/wq(ws/su/npdessw (click on `General Permits' tab) to review that information
for your specific General Permit carefully.

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 HQW, ORW, PNA 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, [: 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 [phone].
Sincerely,

Dear Joe Hack:
It recently cause to the Division's attention that the compliance schedule in the NCG120000 permit is
incorrect. The compliance refers to requiring a Stormwater Pollution Prevention Plan which is not a
requirement of this permit. The corrected compliance language that should go under Part III, Section A: 1_ is
shown below. We have also attached a new page reflecting this change for your permit file (Part III page 1 of
11). This new page should replace the current page in your permit.
SECTION A: COMPLIANCE AND LIABILITY
1. Compliance Schedule
The permittee shall comply with the permit in accordance with the following schedule:
Existing Facilities: Upon the effective date of the Certificate of Coverage the permittee shall comply
with all of the conditions detailed in Part II, Section A: Final Limitations and Controls for Stormwater
Discharges.
New Facilities: Upon the beginning of discharges from the operation of the industrial activity the
permittee shall comply with all conditions detailed in Part H, Section A: Final Limitations and Controls
for Stormwater Discharges.
If you have any questions concerning this matter please contact Aisha Lau at
[phone], ext. 578.
