5.0 SUMMARY OF STORM DRAINAGE OUTFALLS WITH BENCHMARK EXCEEDANCES FOR FECAL COLIFORM
A general BMP description is provided for each documented drainage area shown in Figure 2. A
detailed description of drainage areas with elevated fecal coliform, potential pollutants caused by
associated industrial activities, existing BMPs, and a history of fecal coliform
exceedances/inspections/responses during the permit term is provided below.
5.1 OUTFALL 001
Description: Outfall 001 serves a drainage area of approximately 36.3 acres. Activities within the
drainage area include the active C&D landfill (C&DLF) area. Potential pollutants that may be
expected in the drainage area for Outfall 001 consist of seepage from the C&D landfill and soil
particulate matter resulting from erosion.
Per the permit, the C&DLF must accept only those solid wastes it is permitted to receive. Acceptable
waste for the Cleveland County C&DLF includes:

CLEVELAND COUNTY LANDFILL FACILITY CORRECTIVE ACTION PLAN FOR FECAL COLIFORM
APRIL 2024
(1) Construction and Demolition Debris Waste: (Waste or debris from construction, remodeling,
repair, or demolition operations on pavement or other structures, untreated and unpainted
wood).
(2) Inert Debris Waste: (Concrete, brick, concrete block, uncontaminated soils and rock, etc.).
(3) Land Clearing Debris: as defined by G.S. 120A-290, specifically, waste that is generated
solely from land-clearing activities, such as stumps, trees, etc.
(4) Asphalt: In accordance with G.S. 130-294 (m), demolition debris consisting of used asphalt
or used asphalt mixed with dirt, sand, gravel, rock, concrete, or similar nonhazardous
material may be used as fill and need not be disposed of in a permitted landfill or solid waste
disposal facility. Such demolition debris may not be placed in the waters of the State or at
or below the seasonal high water table.
(5) Construction materials, that could or would be part of any construction, remodeling, repair or
demolition of pavement, buildings or other structures, from solid waste that is generated by
mobile or modular home manufacturers and asphalt shingle manufacturers in the County.
The waste must be source separated at the manufacturing site and must exclude municipal
solid waste, hazardous wastes, and other wastes prohibited from disposal in a C&DLF. It
must be transported to the County C&DLF in a shipment or container that consists solely of
the separated waste to be disposed of. The County C&DLF will not except this waste if it has
not been separated or transported as specified.
(6) Other Wastes as Approved by the Solid Waste Section of the Division of Waste Management.
(7) Asbestos waste: Managed in accordance with 40 CFR 61, which is hereby incorporated by
reference including any subsequent amendments and additions. Copies of 40 CFR 61 are
available for inspection at the Department of Environment and Natural Resources, Division
of Waste Management. The regulated asbestos waste must be covered immediately with
soil in a manner that will not cause airborne conditions and must be disposed of separate
and apart from other solid wastes, as follows:
a. In a defined isolated area within the footprint of the landfill, or
b. In an area not contiguous with other disposal areas. Separate areas must be
designated so that asbestos is not exposed by future land-disturbing activities.
Accepted wastes at the Cleveland County landfill identified in the above list, neither directly
contribute to fecal coliform in stormwater runoff nor attract wildlife vectors which could indirectly
contribute to fecal coliform in stormwater runoff.
Existing BMPs: The drainage area for SDO-001 flows to an engineered storm water/sedimentation
pond with a skimmer, perforated riser, and barrel outlet. The existing outlet structure is designed
for peak flow attenuation during a storm event and settling efficiency to minimize the offsite migration

APRIL 2024
of sediment. Seepage generation is minimized by the application of cover soil on landfilled waste,
thereby reducing the potential for seepage breakouts to the storm water system.
Fecal Coliform Exceedances: All analytical sampling results for SDO-001 for the permit term (July
1, 2021 - June 30, 2026) show exceedances of fecal coliform (see Table 2).
Identified Issues & Proposed Actions:
1. Perimeter ditch erosion into pre-regulatory waste.
While unlikely that pre-regulatory waste should be a significant contributor to fecal coliform
loading at the outfall, the erosion should be repaired, and conservatively treated as a potential
source of fecal coliform contamination. The facility is addressing the exposed waste and ditch
rehabilitation with the North Carolina Department of Environmental Quality (NCDEQ) Division
of Waste Management — Solid Waste Section. Upon approval, plans will be provided to

rehabilitation with the NCDEQ Division of Waste Management — Solid Waste Section. Upon
approval, plans will be provided to DEMLR.

3. Complete drainage of the impoundment for SDO-001 is required, to minimize proliferation of
fecal coliform. Bacteria can survive and grow both within the stormwater system and within
receiving waters. Growth within the stormwater systems includes both the surface and
subsurface conveyances. Coliform bacteria have been found to survive and grow in moist
soils and leaf piles. A recent study in Minneapolis indicated that catch basins are an important
source, largely as a result of growth within the catch basin (MPCA 2020). However, cleanout
of the affected impoundments at the Cleveland County Landfill Facility did not bring fecal
coliform levels below the benchmark in subsequent sampling events. Given that moisture
within the soil encourages growth and proliferation of bacteria, complete drainage of the
impoundment as quickly as allowable, should minimize proliferation of fecal coliform within
the impoundment.
a. The impoundment upstream of SDO-001 (SB-4) is equipped with a skimmer sized for
surface dewatering of the entire impoundment over 3 days (see attached skimmer
sizing for SB-4 in Appendix B). Currently, the skimmer rests on a gravel pad at the
base of the pond, to minimize the inflow of sediment into the skimmer, and therefore
out of the outfall. This pad, while standard, prevents the skimmer from completely
dewatering the basin in wet weather periods. An alternative to the rock pad is a 1- to
2-inch trench below where the skimmer will settle, to allow complete drainage of the
basin while minimizing contact of the skimmer inlet with the bottom of the basin. Given
the increased potential for sediment migration through the skimmer as sediment
collects in the trench, the skimmer and outlet structure should be surrounded by a 2-
foot-high rock berm (d50 = 8 to 10 inches; as show in Figure 4, below, and in the
drawings in Appendix A), to encourage sediment to settle away from the skimmer
while allowing water to flow freely to the outlet devices. The trench should be regularly
inspected after each rainfall event, and cleared of sediment as required.

Proposed Sampling:
All sample locations associated with SDO-001 will be sampled for fecal coliform, in an effort to
narrow down potential source locations for the fecal coliform loading. Soil sampling for fecal coliform
from the bottom of the impoundment will be performed at first opportunity, as allowed by local
weather conditions — to assist in determination of significance of impoundment proliferation
contribution to fecal coliform loading at outfall. Locations potentially affected by the pre-regulatory
waste will be sampled for ammonia, as an indicator of leachate from municipal solid waste. All
locations potentially affected by C&D seeps will be sampled for 40 CFR Part 258 Appendix I
parameters (VOCs and Total Metals), 1,4-dioxane, total phosphorous, sulfate, nitrate, and pH (per
the Leachate Release Sampling & Analysis Guidelines provided by the NC Division of Waste
Management— Solid Waste Section). All sample points are identified on Sheet 1 of the engineering
plans in Appendix A.

5.2 OUTFALL 002
Description: Outfall 002 serves a drainage area of approximately 16.8 acres. Activities within the
drainage area include the active MSW landfill area. The drainage area is kept in an orderly manner,
with no visible clutter.
Potential Pollutants: Potential pollutants that may be expected in the drainage area for Outfall 002
consist of seepage from the MSW landfill and soil particulate matter resulting from erosion.
Existing BMPs: The drainage area flows to an engineered storm water/sedimentation pond with a
perforated riser and barrel outlet. The existing outlet structure is designed for peak flow attenuation
during a storm event and settling efficiency to minimize the offsite migration of sediment. Seepage
generation is minimized by the application of cover soil on landfilled waste, thereby reducing the
potential for seepage breakouts to the storm water system.
Fecal Coliform Exceedances: No discharge from SDO-002 has occurred during the permit term
(July 1, 2021 - June 30, 2026), as the barrel pipe to the outlet of SDO-002 has a positive slope.
Proposed Actions:
1. The outlet of the barrel pipe for SDO-002 is in a depression in the local topography. Future
analytical sampling for SDO-002 will be performed at the surface of any ponding at the outfall
location, as able.

Proposed Sampling:
All sample locations associated with SDO-002 will be sampled for fecal coliform, in an effort to
narrow down potential source locations for the fecal coliform loading. All locations associated with
SDO-002 will also be sampled for ammonia as an indicator for the potential presence of landfill
leachate from municipal solid waste. All sample points are identified on Sheet 1 of the engineering
plans in Appendix A.

Note: Additionally, a sample from the leachate collection tanks will be tested for fecal coliform and
ammonia, for use in the determination of the potential of facility landfill leachate as a source of those
parameters in stormwater runoff. The leachate tank sample valve is identified as FC-7 on Sheet 1
of the engineering plans in Appendix A.
5.3 OUTFALL 003
Description: Outfall 003 serves a drainage area of approximately 10.9 acres. Activities within the
drainage area include the active C&D landfill area and Equipment Maintenance Shop. Potential
pollutants that may be expected in the drainage area for Outfall 003 consist of seepage from the
C&D landfill, oil/grease from the maintenance area, and soil particulate matter resulting from
erosion.
Accepted wastes at the Cleveland County C&DLF, as discussed in Section 5.1 above, neither
directly contribute to fecal coliform in stormwater runoff nor attract wildlife vectors which could
indirectly contribute to fecal coliform in stormwater runoff.
Existing BMPs: The drainage area flows to an engineered storm water/sedimentation pond with a
skimmer, perforated riser, and barrel outlet. The existing outlet structure is designed for peak flow
attenuation during a storm event and settling efficiency to minimize the offsite migration of sediment.
Seepage generation is minimized by the application of cover soil on landfilled waste, thereby
reducing the potential for seepage breakouts to the storm water system.
Fecal Coliform Exceedances: All analytical sampling results for SDO-003 for the permit term (July
1, 2021 - June 30, 2026) show exceedances of fecal coliform (see Table 2).

Identified Issues & Proposed Actions:
1. The gravel area in the drainage area to SDO-003 had been being used to store empty rolloff
containers from Cleveland County convenience centers, some of which had been used to
collect municipal solid waste (see drainage area 3 with aerial imagery on Sheet 1 of the
engineering plans in Appendix A). Some residual waste remaining in the containers after
they had been empty was observed outside of the containers, within the drainage area to
SDO-003.
a. Empty rolloff containers that have contained municipal solid waste will no longer be
stored in the drainage area to SDO-003, and will no longer be a potential source of
pollutants unrelated to industrial activity within the drainage area to SDO-003.
2. Ditches around the perimeter of the gravel area within the drainage area were observed to
contain standing water, with nowhere to drain.
a. These ditches serve no significant stormwater management purpose, and should be
backfilled and seeded to prevent standing water and allow stormwater runoff to sheet
flow to the impoundment for SDO-003 (see Sheet 1 of the engineering plans in
Appendix A).
3. Ensure good coverage of disposed C&D waste and seed intermediate cover areas with
permanent seeding mix, as needed. Permanent seeding mixture described on Sheet 2 of the
engineering plans in Appendix A.
4. Complete drainage of impoundment required, to minimize proliferation of fecal coliform, as
discussed for SDO-001, above. Given that moisture within the soil encourages growth and
proliferation of bacteria, complete drainage of the impoundment as quickly as allowable,
should minimize proliferation of fecal coliform within the impoundment.
a. The impoundment upstream of SDO-003 (SB-5) is equipped with a skimmer sized for
surface dewatering of the entire impoundment over 3 days (see attached skimmer
sizing for SB-5 in Appendix B). This outfall is currently under corrective action for
total suspended solids. The skimmer rests on a gravel pad at the base of the pond, to
minimize the inflow of sediment into the skimmer, and therefore out of the outfall. This
pad, while standard, prevents the skimmer from completely dewatering the basin in
wet weather periods. An alternative to the rock pad is a 1- to 2-inch trench below
where the skimmer will settle, to allow complete drainage of the basin while minimizing
contact of the skimmer inlet with the bottom of the basin. Given the increased potential
for sediment migration through the skimmer as sediment collects in the trench, the
skimmer and outlet structure should be surrounded by a 2-foot-high rock berm (d50 =
8 to 10 inches; as shown in Figure 4, above, and in the drawings in Appendix A), to
encourage sediment to settle away from the skimmer while allowing water to flow

freely to the outlet devices. The trench should be regularly inspected after each rainfall
event and cleared of sediment as required.
Proposed Sampling:
All sample locations associated with SDO-003 will be sampled for fecal coliform, in an effort to
narrow down potential source locations for the fecal coliform loading. Soil sampling for fecal coliform
from the bottom of the impoundment will be performed at first opportunity, as allowed by local
weather conditions — to assist in determination of significance of impoundment proliferation
contribution to fecal coliform loading at outfall. Locations potentially affected by stormwater from the
rolloff containers will be sampled for ammonia, as an indicator of leachate from municipal solid
waste. All sample points are identified on Sheet 1 of the engineering plans in Appendix A.

5.4 OUTFALL 004
Description: Outfall 004 serves a drainage area of approximately 2.8 acres. Activities within the
drainage area include the active MSW landfill area. The drainage area is kept in an orderly manner,
with no visible clutter.
Potential Pollutants: Potential pollutants that may be expected in the drainage area for Outfall 004
consist of seepage from the MSW landfill and soil particulate matter resulting from erosion.
Existing BMPs: The drainage area flows to an engineered storm water/sedimentation trap with a
rock dam outfall. The existing outlet structure is designed for peak flow attenuation during a storm
event and settling efficiency to minimize the offsite migration of sediment. Seepage generation is
minimized by the application of cover soil on landfilled waste, thereby reducing the potential for
seepage breakouts to the storm water system.
Fecal Coliform Exceedances: No discharge from SDO-004 has occurred during the permit term
(July 1, 2021 - June 30, 2026).
Proposed Actions:
1. Analytical sampling at the rock dam outlet for SDO-004 has proven difficult to identify during
sampling events.

future sampling for SDO-004 (see Sheet 2 of the engineering plans in Appendix A).
Proposed Sampling:
All sample locations associated with SDO-004 will be sampled for fecal coliform, in an effort to
narrow down potential source locations for the fecal coliform loading. All sample locations
associated with SDO-004 will also be sampled for ammonia as an indicator for the potential
presence of landfill leachate from municipal solid waste. All sample points are identified on Sheet 1

parameters in storm water runoff; (2) SW-101 (upstream) and SW-104 (downstream) surface water samples
will be sampled as discussed for SDO-002.
5.5 OUTFALL 005
Description: Outfall 005 serves a drainage area of approximately 9.4 acres. Activities within the
drainage area include the active MSW landfill area. The drainage area is kept in an orderly manner,
with no visible clutter.
Potential Pollutants: Potential pollutants that may be expected in the drainage area for Outfall 005
consist of seepage from the MSW landfill and soil particulate matter resulting from erosion.

5.6 OUTFALL 006
Description: Outfall 006 serves a drainage area of approximately 33.9 acres. Activities within the
drainage area include the active MSW landfill area. Potential pollutants that may be expected in
the drainage area for Outfall 006 consist of seepage from the MSW landfill and soil particulate matter
resulting from erosion.
Existing BMPs: The drainage area flows to an engineered storm water/sedimentation pond with a
perforated riser and barrel outlet. The existing outlet structure is designed for peak flow attenuation
during a storm event and settling efficiency to minimize the offsite migration of sediment. Seepage
generation is minimized by the application of cover soil on landfilled waste, thereby reducing the
potential for seepage breakouts to the storm water system.
Fecal Coliform Exceedances: The initial and only exceedance of fecal coliform at SDO-006 was
6,700 MPN/100 mL on March 27, 2023. There was no discharge at SDO-006 for analytical sampling
in the remaining sampling events of the permit term (July 1, 2021 - June 30, 2026).
Proposed Actions:
1. Allow for sampling of the outlet of the culvert under the road into the drainage area for
SDO-006, at sample point FC-18 on Sheet 1 of the engineering plans in Appendix A, by
clearing the vegetation from around the outlet.
2. Allow for proper drainage from SDO-006, by trenching a drainage pathway from the outlet
pipe across the road. Line the trench with erosion control matting and backfill with Class

A riprap, to allow for both drainage and continued use of the existing road (see Sheets 1
and 2 of the engineering plans in Appendix A).
Proposed Sampling:
All sample locations associated with SDO-006 will be sampled for fecal coliform, in an effort to
narrow down potential source locations for the fecal coliform loading. Soil sampling for fecal coliform
from the bottom of the impoundment will be performed at first opportunity, as allowed by local

parameters in storm water runoff; (2) SW-101 (upstream) and SW-104 (downstream) surface water samples
will be sampled as discussed for SDO-002.
5.7 OUTFALL 007
Description: Outfall 007 serves a drainage area of approximately 30.6 acres. Activities within the
drainage area include the active MSW landfill area and a shop building. Potential pollutants that
may be expected in the drainage area for Outfall 007 consist of seepage from the MSW landfill, oil
and grease from the shop area, and soil particulate matter resulting from erosion.
Existing BMPs: The drainage area flows to an engineered storm water/sedimentation pond with a
skimmer, perforated riser, and barrel outlet. The existing outlet structure is designed for peak flow
attenuation during a storm event and settling efficiency to minimize the offsite migration of sediment.
Seepage generation is minimized by the application of cover soil on landfilled waste, thereby
reducing the potential for seepage breakouts to the storm water system.
Fecal Coliform Exceedances: All analytical sampling results for SDO-007 for the permit term (July
1, 2021 - June 30, 2026) show exceedances of fecal coliform (see Table 2), with the exception of
the January 2024 sampling event. During the January 2024 sampling event the fecal coliform
samples were out of hold time when tested due to lab error; adverse weather conditions caused
widespread damage to drainage areas, and is the event is not considered characteristic of volume
and nature of permitted discharge from the facility.

Proposed Actions:
1. Complete drainage of impoundment required, to minimize proliferation of fecal coliform, as
discussed for SDO-001, above. Given that moisture within the soil encourages growth and
proliferation of bacteria, complete drainage of the impoundment as quickly as allowable,
should minimize proliferation of fecal coliform within the impoundment.
a. The impoundment upstream of SDO-007 (Sediment Basin 8) is equipped with a
skimmer designed for surface dewatering of the entire impoundment over (see
attached skimmer detail for SB-8 in Appendix C). Given the current volume, this
skimmer should be replaced with a skimmer as specified in Appendices A and B.
The existing skimmer currently rests on a gravel pad at the base of the pond, to
minimize the inflow of sediment into the skimmer, and therefore out of the outfall. This
pad, while standard, prevents the skimmer from completely dewatering the basin in
wet weather periods. An alternative to the rock pad is a 1- to 2-inch trench below
where the skimmer will settle, to allow complete drainage of the basin while minimizing
contact of the skimmer inlet with the bottom of the basin. Given the increased potential
for sediment migration through the skimmer as sediment collects in the trench, the
skimmer and outlet structure should be surrounded by a 2-foot-high rock berm (d50 =
8 to 10 inches; as shown in Figure 4, above, and in the drawings in Appendix A), to
encourage sediment to settle away from the skimmer while allowing water to flow
freely to the outlet devices. The trench should be regularly inspected after each rainfall
event and cleared of sediment as required.
Proposed Sampling:
All sample locations associated with SDO-007 will be sampled for fecal coliform, in an effort to

will be sampled as discussed for SDO-002.
5.8 OUTFALL 008
Description: Outfall 008 serves a drainage area of approximately 13.6 acres. Activities within the
drainage area generally consist of soil borrow operations. The potential pollutant that may be
expected in the drainage area for Outfall 008 as a result of the industrial activity consist of total
suspended solids (soil particulates) resulting from erosion. Fecal coliform identified in samples
taken from SDO-008 is unrelated to industrial activities within the drainage area.
Existing BMPs: The drainage area flows to an engineered storm water/sedimentation pond with a
perforated riser and barrel outlet. The existing outlet structure is designed for peak flow attenuation
during a storm event and settling efficiency to minimize the offsite migration of sediment.
Fecal Coliform Exceedances: The first and only exceedance of fecal coliform at SDO-008 was 3,100
MPN/100 mL on August 13, 2023. Fecal coliform levels were under the benchmark for the sampling
events in November 2022 and January 2024. There was no discharge at SDO-008 for analytical
sampling in the remaining sampling events of the permit term (July 1, 2021 - June 30, 2026) — see
Table 2.
Proposed Actions:
1. When weather permits, clean out impoundment and ensure the impoundment is at designed
grade.
2. Complete drainage of impoundment required, to minimize proliferation of fecal coliform, as
discussed for SDO-001, above. Given that moisture within the soil encourages growth and
proliferation of bacteria, complete drainage of the impoundment as quickly as allowable,
should minimize proliferation of fecal coliform within the impoundment.
a. The impoundment upstream of SDO-008 (Riser Basin SP1) is equipped with a
perforated riser (see attached detail for SP1 in Appendix C). The outlet device is
damaged, which likely occurred during cleanout of the basin. Rather than repairing
the existing outlet device, the riser basin will be improved via conversion into a
skimmer sediment basin (see design calculations in Appendix B and drawings in
Appendix A). The existing perforated riser will be removed and replaced with a non-
perforated riser with a skimmer for surface dewatering. Thie skimmer will rest above
a 1- to 2-inch trench, to allow complete drainage of the basin while minimizing contact
of the skimmer inlet with the bottom of the basin. The skimmer and outlet structure

should be surrounded by a 2-foot-high rock berm (d50 = 8 to 10 inches; as shown in
Figure 4, above, and in the drawings in Appendix A), to encourage sediment to settle
away from the skimmer while allowing water to flow freely to the outlet devices. The

for SDO-002.
5.9 OUTFALL 009
Description: Outfall 009 serves a drainage area of approximately 6.2 acres. Activities within the
drainage area generally consist of soil borrow operations. The drainage area is kept in an orderly
manner, with no visible clutter.
Potential Pollutants: Potential pollutants that may be expected in the drainage area for Outfall 009
consist of soil particulate resulting from erosion.
Existing BMPs: The drainage area flows to an engineered storm water/sedimentation pond with a
perforated riser and barrel outlet. The existing outlet structure is designed for peak flow attenuation
during a storm event and settling efficiency to minimize the offsite migration of sediment.
Fecal Coliform Exceedances: No discharge from SDO-009 has occurred during the permit term
(July 1, 2021 - June 30, 2026).
Proposed Actions:
1. Outfall must be between the industrial activity and the closest surface water. As the
existing outfall point is difficult to sample during a rainfall event (in a localized depression
that submerges due to ponding), the outfall/sample point for SDO-009 will be moved to
the end of the pipe that collects all drainage from the pond, identified as SDO-009A on
Sheet 1 of the engineering plans in Appendix A.

Note: SDO-009 may not currently receive any industrial stormwater — to be evaluated
following the next annual facility survey in June/July 2024.
Proposed Sampling:
All sample locations associated with SDO-009 will be sampled for fecal coliform, in an effort to
narrow down potential source locations for the fecal coliform loading. Soil sampling for fecal coliform
from the bottom of the impoundment will be performed at first opportunity, as allowed by local

Sampling Notes:
• Impoundment soil samples should only be taken when water is completely drained from
impoundment.
• Diversions can only be sampled when water is flowing through them.
• As able, sample points (other than soil samples) should be sampled during the same rainfall
event as a sample collected from the associated outfall.
• Ammonia is used as an alternative indicator for the presence of MSW leachate in relevant
samples.
7.0 CONCLUSIONS
Following the recommendations provided to Cleveland County during the facility inspection on March
7, 2024, this corrective action plan proposes actions in each drainage area which may reduce the fecal
coliform loading at facility outfalls, as well as establishing a sampling plan to help identify, narrow down,
and/or rule out potential sources of fecal coliform at the facility.
This proposed Corrective Action will be implemented as soon as this action plan is approved by
DEMLR. Construction required by this corrective action plan will be completed within 6 months, weather
permitting, and sampling will be completed as soon as feasible. Construction and sampling associated
with the corrective action will be performed by Cleveland County Landfill Facility Staff, or subcontracted
as required.
Following the completion of construction and receipt of lab results for all proposed sampling, a report
summarizing the results of the corrective action and sampling will be provided to DEMLR within 30
days, along with any recommendations for future actions at the facility.
Per the Tier Three response required by NCG120000, monthly monitoring will continue at all Tier Three
outfalls until three consecutive samples are below the benchmark value for fecal coliform.

Subject: COMPLIANCE EVALUATION INSPECTION and
TIER RELIEF REQUEST FOR FECAL COLIFORM RESPONSE
NPDES Stormwater General Permit NCG120000
Cleveland County Landfill
Certificate of Coverage NCG120072
Cleveland County
Dear Mr. Davis:
On March 7, 2024, a site inspection was conducted for the Cleveland County Landfill facility located at 250
Fielding Road, Cherryville, Cleveland County, North Carolina. A copy of the Compliance Inspection Report is
enclosed for your review. The site visit and file review revealed that the subject facility is covered by NPDES
Stormwater General Permit NCG 120000 under Certificate of Coverage NCG 120072. Permit coverage authorizes
the discharge of stormwater from the facility to receiving waters designated as Buffalo Creek, Long Creek, and
Smith Creek, Class WS-III and C;Sw waters in the Broad River Basin.
The facility's paperwork related to the referenced permit appeared compliant; however, the site-wide compliance
status was not evaluated at this time because of the seeps and sampling issues identified. Please refer to the
enclosed Compliance Inspection Report for additional comments and observations made during the inspection.
Additionally, on October 18, 2023, the Department of Environmental Quality received a Tier Relief Request for
Fecal Coliform for the facility. As a result of the referenced inspection, the tier relief request is denied. Multiple
potential sources and reasons for the fecal levels reported at the facility need to be addressed prior to a tier relief
request being considered.
Please be advised that violations of the NPDES Stormwater General Permit are subject to a civil penalty
assessment of up to $25,000 per day for each violation. If you or your staff have any questions, comments, or
need assistance with understanding any aspect of your permit, please contact me at(704) 235-2100 or via e-mail at

Inspection Summary:
Jerry Eplin and Isaiah Reed with DEMLR conducted a compliance evaluation inspection for the referenced facility. The
facility requested Tier Monitoring Relief in relation to elevated fecal results reported at multiple facility outfalls
During the inspection, it was found that the Stormwater Pollution Prevention Plan(SWPPP)was present and had been
updated within the last year. Likewise,training had been perforemd within the last year. Non-discharge/illicit discharge
monitoring records exist, however,the referenced monitoring is not sufficient to evalute non-stormwater discharges. Facility
personnel and/or their consultant indicated that monitoring involves activities similar to Qualitiative Monitoring and that dry
weather observions of the outfalls is not possible because the basins discharge nearly continuously. However, basins are
supposed to completely dewater in 3-5 days. Repairs to basin outlet structures are needed so that they completely
dewater within the required time frame. Additional, a damaged riser and damaged barrel pipe were observed in SP-1, Outfall
8. Repairs are needed.
During the inspection, several potential leachate seeps were identified. Furthermore, a water feature was found cutting into
an area of apparently burned Municipal Solid Waste,exposing the waste. Tier Monitoring Relief is not appropriate. The
facility should work with the Division of Solid Waste to address the leachate and MSW issues outlined above.

#Has the facility conducted its Analytical monitoring from Vehicle Maintenance areas? M 0 0 0
Comment: Note that while the facility is conducting analytical monitoring,there are some outfalls that are
not being monitored because the outfall, as configured, does not allow a true grab stormwater
sample. However, it appears that with maintenance, additional outfalls could be monitored and
that maintenance is recommended.
Permit and Outfalls
Yes No NA NE
#Is a copy of the Permit and the Certificate of Coverage available at the site? M 0 0 ❑
#Were all outfalls observed during the inspection? MOOD
#If the facility has representative outfall status, is it properly documented by the Division? ❑ ❑ ❑
#Has the facility evaluated all illicit(non stormwater)discharges? M 0 0 ❑
Comment: The facility has documented illicit discharge monitoring records, however, as performed the
monitoring is insufficient to evaluate non-stormwater discharges. Basins do not appear to be
draining within 3 -5 days of a rain event. Basin discharge structures should be maintained so
that the basin dewaters within required timeframes. Basins with damaged risers and/or barrel
pipes should be repaired.
