Permit and Outfalls Yea No NA NE
# Is a copy of the Permit and the Certificate of Coverage available at the site? ❑ ❑ ❑
# Were all outfalls observed during the inspection? E ❑ ❑ ❑
# If the facility has representative outfall status, is it properly documented by the Division? ❑ 110 ❑
# Has the facility evaluated all illicit (non storrnwater) discharges? N ❑ ❑ ❑
Comment: The outfall were evaluated for TTS and fecal coliform impacts. Outfall LL-2 can be impacted b
unstable basin slopes in the upper pond and lower pond. Slopes should be armored with large
stone or regraded and stabilized with seed and matting. Outfalis LL-1 and LL-3 should not be
impacted by unstable up gradient slopes. Fecal coliform impacts very widely and no
recommendations can be made at this time to reduce potential impacts. Long term LL-1 is the
best place to sample for the West side drainage area.

Buxton Environmental, Inc. respectfully submits the Monthly Qualitative and Analytical Storm Water
Monitoring — Month 96, 2016 report for the Gaston County Landfill — Hardin Site located at 3155
Philadelphia Church Road in Dallas, North Carolina. Storm water monitoring activities were conducted
at storm water basins associated with the construction & demolition (C&D) landfill over the closed
unlined municipal solid waste (MSW) landfill, Unit I lined MSW landfill, Unit U lined MSW landfill,
vehicle maintenance garage and the yard waste composting facility. The National Pollutant Discharge
Elimination System (NPDES) General Permit Number for the site is NCG120012. These activities were
conducted in general accordance with North Carolina Department of Environmental Quality, Division of
Water Quality (NCDEQ-DWQ) guidelines for Part II Monitoring, Controls, and Limitations for Permitted
Discharges (Appendix A). According to the 5 year permit, storm water monitoring is required to be
conducted from January 1, 2013 to October 31, 2017. A site layout map is provided in Figure 1.
According to NCDEQ-DWQ guidelines, qualitative storm water monitoring and analytical storm water
sampling should be conducted during a "measurable storm event", which is a storm that results in an
actual discharge from the permitted site outfalls; and is preceded by at least 72 hours in which no
"measurable storm event" has occurred. In addition, rain totals should be obtained from an on -site rain
gauge.

1.0 BACKGROUND INFORMATION
Buxton Environmental, Inc. understands that the Gaston County Landfill - Hardin Site has been in
operation since approximately 1985. The subject facility presently contains four landfill areas, which
include a closed C&D landfill, an active C&D landfill over a closed unlined MSW landfill, an active
Subtitle D lined MSW landfill (Unit I) and an additional active Subtitle D lined MSW landfill (Unit I1).
Heavy equipment utilized for landfill activities is serviced at the on -site vehicle maintenance garage.
Yard waste is also temporarily stockpiled then ground into mulch or composted at an on -site facility.
Storm water monitoring has been conducted at the site by Buxton Environmental, Inc. since 1997.
As required by the NPDES General Permit, Bunton Environmental, Inc. conducts Visual Inspections of
the Gaston County Landfill — Hardin Site once every seven (7) calendar days and within 24-hours after
any storm event greater than 0.5-inches per 24-hour period, in order to ensure the integrity and
effectiveness of storm water, sedimentation and erosion controls. Written records are maintained on -site.
On June 26, 2013, Buxton Environmental, Inc. conducted the initial Year 1 - Period 1, 2013 analytical
storm water sampling activities at storm water detention pond outfalls LLO-1, LLO-2, LLO-3 and ULO-1
associated with the Unit I lined MSW landfill, Unit 11 lined MSW landfill, and/or C&D landfill over the
closed unlined MSW landfill; the vehicle maintenance garage storm water detention pond outfall MG-1;
and the yard waste composting facility storm water detention pond outfall YW-1. Storm water samples
LLO-1, LLO-2, LLO-3, ULO-1, MG-1 and YW-1 indicated target constituents above Benchmark Values.
Historical storm water analytical results are presented in Table 1.
Based on these results, Buxton Environmental, Inc. initiated a Tier One response on July 9 and 18, 2013
to evaluate the cause of and attempt to correct exceedances in storm water Benchmark Values
encountered at LLO-1, LLO-2, LLO-3, ULO-1, MG-1 and YW-1. During these activities, Buxton
Environmental, Inc. recommended that the following items be addressed: 1) rills observed on the east side
of the C&D landfill over the unlined landfill should be filled and vegetated; 2) rills observed on the south
and east sides of Unit I MSW landfill should be filled and vegetated; 3) rills on observed on the south side
of Unit II MSW landfill should be filled and vegetated; 4) a washout on the backside of the lower LLO-2
detention pond dam should be backfilled with soil and secured with a rock boulder cover; 5) storm water
drainage at the soil borrow area on the southwest comer of the Unit 11 MSW landfill should be re -directed
to flow into the lower LLO-1 detention pond, a washout at the soil borrow area should be filled and
vegetated, and sediment fencing should be installed in the area; 6) storm water detention ponds LLO-1,
LLO-2 (upper and lower), LLO-3 and ULO-1 should be excavated to remove accumulated sediment; 7)
non -vegetated areas at the landfill should be seeded to stabilize soils; and 8) discourage the presence of
vectors (primarily seagulls, buzzards and rodents) at the site in order attempt to reduce fecal coliform
concentrations in the storm water. The above recommended improvements were conducted by Gaston
County Landfill from August through early December 2013. In addition, Gaston County Landfill placed
crushed stone along heavily travel dirt roads, and created boulder baffles and small interceptor basins
along drainage ditches in the area of the C&D landfill over the unlined landfill, Unit I MSW landfill and
Unit II MSW landfill, in order to attempt to reduce total suspended solid (TSS) concentrations in storm
water.

On November 26, 2014, Buxton Environmental, Inc. conducted the Year 1 - Period 2, 2013 analytical
storm water sampling activities at storm water detention pond outfalls LLO-1, LLO-2, LLO-3, ULO-1,
MG-1 and YW-1. Storm water samples LLO-1, LLO-2, LLO-3, ULO-1, MG-1 and YW-1 indicated
target constituents above Benchmark Values. Based on these findings, a Tier Two response was required
to be conducted, since exceedances in storm water Benchmark Values were encountered at LLO-1, LLO-
2, LLO-3, ULO-1, MG -I and YW-1 two (2) times in a row. A Tier Two response includes: 1) repeating
the Tier One response to evaluate the cause of and attempt to correct exceedances in storm water
Benchmark Values and 2) immediately institute monthly analytical and qualitative monitoring at every
outfall exceeding Benchmark Values until three consecutive samples are below Benchmark Values.
Historical storm water analytical results are presented in Table 1.
On January 13, 2014, Mr. Bradley Bennett with the NCDENR-DWQ was contacted to discuss typical
actions taken by the NCDEQ-DWQ once storm water Benchmark Values are exceeded for four (4)
occasions at an outfall during the term of the permit. Mr. Bennett indicated that the Regional NCDEQ-
DWQ project manager should be contacted and they will become involved to attempt to reduce the storm
water exceedances. Mr. Bennett indicated that he was unaware of any NPDES permits being rescinded,
as long as efforts are being made to improve storm water quality.
On February 18, 2014, Mr. Ross Klingman, P.G. with Buxton Environmental, Inc. conducted a Tier One
storm water management inspection within drainage areas that flow to storm water outfalls LLO-1, LLO-
2, LLO-3, ULO-1, MG-1 and YW-1 to identify possible causes of Benchmark Value exceedances. Based
on historical storm water sampling, surface water samples periodically indicated the presence of chemical
oxygen demand (COD) above Benchmark Values and have consistently indicated the presence of fecal
coliform and TSS above Benchmark Values. Based on the inspection, several corrective measure
recommendations were made to attempt to improve surface water quality at the site and are presented in
the Tier One Storm Water Management Inspection report prepared on March 4, 2014 by Buxton
Environmental, Inc.
On March 3, 2014, Buxton Environmental, Inc. conducted the first monthly analytical storm water
monitoring event (Month #3, 2014) at storm water detention pond outfalls LLO-1, LLO-2, ULO-1, MG-1
and YW-1. No storm water discharge occurred at LLO-3, therefore, sampling was unable to be
conducted. Storm water samples LLO-1, MG -I and YW-I indicated target constituents above
Benchmark Values. Based on these and historical findings, a Tier Two response was required to be
conducted which includes 1) monthly analytical and qualitative monitoring at every outfall exceeding
Benchmark Values until three consecutive samples are below Benchmark Values and 2) implementing the
corrective measure recommendations to attempt to improve surface water quality at the site, which are
presented in the Tier One Storm Water Management Inspection report prepared on March 4, 2014. In the
event that storm water Benchmark Values are exceeded for four (4) occasions at an outfall during the term
the permit, the NCDEQ-DWQ is required to be notified in writing within 30-days of receipt of the fourth
analytical results. Historical storm water analytical results are presented in Table 1.

From March lb, 2014 through March 21, 2015, Gaston County Landfill conducted extensive storm water
quality corrective measure improvements at the site, as recommended in the Tier One Storm Water
Management Inspection report prepared on March 4, 2014. A summary of the main improvements
included: 1) excavating accumulated sediments from storm water detention ponds LLO-2 (upper and
lower), ULO-1 and MG-1; 2) the placement of new gravel filter pack around the vertical discharge pipes
at LLO-2 (upper and lower) ponds and ULO-1 pond; 3) the installation of rock baffles in drainage ditches
along the south side of the Unit I landfill; 4) re -grading and hydro -seeding of non -vegetated side slopes at
the Unit I MSW landfill, Unit 11 MSW landfill, and C&D landfill over closed unlined MSW landfill; and
5) the installation of a small temporary sediment basin in the open soil borrow area to the east of the C&D
landfill over closed unlined MSW landfill, and the southeast comer of the Unit II MSW landfill. A
detailed log of written field observations and improvements are maintained on -site -
On March 26, 2014, Mr. Ryan Kormanik with the NCDEQ conducted a storm water Compliance
Evaluation Inspection at the Gaston County Landfill — Hardin Site. According to the Compliance
Inspection Report dated March 31, 2014, the landfill was in compliance with the NPDES permit. Mr.
Kormanik recommended that the sediment basins be updated to a newer design to assist with reducing the
TSS concentrations, and requested that coir mesh baffles be installed in the sediment basins.
On February 9, 2015, Buxton Environmental, Inc. conducted monthly analytical and qualitative storm
water monitoring (Month #2, 2015) at storm water detention pond outfalls LLO-2, U1,0-1, MG-1 and
YW-1. No storm water discharge occurred at LLO-1 and LLO-3, therefore, monitoring was unable to be
conducted. Storm water sample MG-1 indicated the presence of TSS above Benchmark Values, which
was above the Benchmark Value for the fourth (4`h) occasion since sampling began for the current
NPDES permit. However, the storm water sample collected on February 9, 2015 at LLO-2 (located down
stream of MG-1) did not indicate TSS above the Benchmark Value. Storm water samples LLO-2, ULO-1
and YW-1 did not indicate target constituents above Benchmark Values. The methods, results and
recommendations of these activities were documented in the Monthly Analytical and Qualitative Storm
Water Monitoring — Month 42, 2015 report prepared by Buxton Environmental, Inc. on April 23, 2015.
Historical storm water analytical results are presented in Table 1.
From April 3, 2015 through February 18, 2016, Gaston County Landfill conducted routine storm water
quality corrective measure improvements at the site, as part of Tier Two response procedures. A
summary of the main improvements included: 1) excavation of accumulated sediments from storm water
detention ponds LLO-2 (upper and lower), and the small temporary sediment basin located on the
southwest corner of the Unit II landfill; 2) the placement of new gravel filter pack around the vertical
discharge pipes at LLO-2 (upper and lower) ponds; 3) the creation of a new sediment basin on the
northeast comer of the Unit II landfill; 4) re -grading and hydro -seeding the non -vegetated side slopes at
the Unit II landfill, and east side of the C&D landfill over closed unlined landfill; 5) the installation of
sediment fencing on the south toe of C&D landfill over closed unlined landfill; and 6) the repair of rills at
Unit 11 and the east side of the C&D landfill over closed unlined landfill. Based on the visual storm water
inspection conducted on February 18, 2016, all newly hydra -seeded slopes at the site had germinated and
contained well established vegetative cover; however, and an effort should be made to deter seagulls and
buzzards at the site_ A detailed log of written field observations and improvements are maintained on-

2.2 Monthly Analytical Storm Water Sampling Activities
Unit I Lined MSW Landfill, Unit II Lined MSW Landfill, and Construction & Demolition Landfill
Over Closed Unlined MSW Landfill
On June 27, 2016, Buxton Environmental, Inc. conducted monthly analytical storm water sampling
activities at storm water detention pond outfalls LLO-1, LLO-2, LLO-3 and ULO-I. A total of 2-inches
of rain occurred over an approximately 1 hour period, just prior to sampling on June 27, 2016. The storm
water samples were analyzed for COD by Method SM52201), fecal coliform by Method SM9222D and
TSS by Method SM2540D by Prism Laboratories, Inc. in Charlotte, North Carolina.
Vehicle Maintenance Garage
The NCDEQ-DWQ guidelines for Part H Monitoring, Controls, and Limitations for Permitted
Discharges indicates that storm water sampling is required if new motor oil usage at the on -site vehicle
maintenance facility exceeds 55-gallons per month when averaged over a calendar year. New motor oil
use at the vehicle maintenance facility has historically exceeded the 55-gallon per month average,
therefore, storm water monitoring was conducted_
On June 27, 2016, Buxton Environmental, Inc. conducted monthly analytical storm water sampling at the
vehicle maintenance garage storm water detention pond outfall MG-1. Drainage from MG-1 is located
approximately 2,400 feet upstream of LLO-2, and each are located along the same drainage swale. A
total of 2-inches of rain occurred over an approximately 1 hour period, just prior to sampling on June 27,
2016. The storm water samples were analyzed for TSS by Method SM2540D, oil and grease by Method
1664B, and pH by Method SM4500-HB (for verification purposes). The storm water was also field tested
for pH with an appropriately calibrated EXTECH Instruments pH meter by Buxton Environmental, Inc.
Yard Waste Composting Facility
On June 27, 2016, Buxton Environmental, Inc. conducted storm water monitoring at the yard waste
composting facility storm water detention pond outfall YW-1. A total of 2-inches of rain occurred over
an approximately 1 hour period, just prior to sampling on June 27, 2016. The storm water samples were

3.0 RECOMMENDATIONS
Based on the findings of this investigation, Buxton Environmental, Inc. makes the following
recommendations.
• Tier Two responses should continue to be conducted at the site, which include: 1) monthly
analytical and qualitative monitoring at every outfall exceeding Benchmark Values until three
consecutive samples are below Benchmark Values; and 2) Tier One responses which include
continued evaluation of the cause of and attempts to correct exceedances in storm water
Benchmark Values.
The Regional NCDEQ-DWQ is required to be notified in writing within 30-days of receipt of
analytical results indicating that target storm water parameters have exceeded Benchmark Values
for four (4) occasions at an outfall during the term the permit. Storm water sample LLO-1
indicated fecal coliform and TSS above the Benchmark Values for the fifth (5'h) occasion. Storm
water sample LLO-2 indicated fecal coliform above the Benchmark Values for the fourth (411)
occasion. Storm water sample MG-1 indicated the presence of TSS above the Benchmark Value
for the sixth (6`h) occasion (however, storm water sample LLO-2 (located down stream of MG-1)
has only indicated TSS above the Benchmark Value on three (3) occasions). Storm water sample
YW-1 indicated fecal coliform above the Benchmark Values for the fourth (4d) occasion.
• A continued effort should be made to attempt to reduce TSS concentrations; and an effort should
be made to deter vectors to attempt to reduce fecal coliform concentrations at the site, as indicated
in the May 24, 2016 Tier One Storm Water Management Inspection report.
• A copy of this report should be maintained at the Gaston County Landfill — Hardin Site.
A copy of this report should also be submitted by Gaston County to the NCDEQ-DWQ for review.

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/l 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, 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 clays 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,

PART I INTRODUCTION
SECTION A: GENERAL PERMIT COVERAGE
All persons desiring to be covered by this General Permit must register with the Division of Water Quality
(DWQ) by the filing of a Notice of Intent (NOI) and applicable fees. The NOI shall be submitted and a
certificate of coverage issued prior to any point source discharge of stormwater associated with industrial
activity to the surface waters of the state.
Any owner or operator not wishing to be covered or limited by this General Permit may make application
for an individual NPDES permit in accordance with NPDES procedures in 15A NCAC 2H .0100, stating the
reasons supporting the request Any application for an individual permit should be made at least 180 days
prior to commencement of discharge.
This General Permit does not cover activities or discharges covered by an individual NPDES permit until the
individual permit has expired or has been revoked. Any person conducting an activity covered by an
individual permit but which could be covered by this General Permit may request that the individual permit
be revoked and coverage under this General Permit be provided.
If industrial materials and activities are not exposed to precipitation or runoff as described in 40 CFR
§122.26(g), the facility may qualify for a No Exposure Exclusion from NPDES stormwater discharge permit
requirements. Any owner or operator wishing to obtain a No Exposure Exclusion must submit a No
Exposure Certification Notice of Intent (NOI) form to the Division; must receive approval by the Division;
must maintain no exposure conditions unless authorized to discharge under a valid NPDES stormwater
permit; and must recertify the No Exposure Exclusion annually.
Any facility may apply for new or continued coverage under this permit until a Total Maximum Daily Load
(TMDL) for pollutants for stormwater is established. A TMDL sets a pollutant -loading limit that affects a
watershed, or portion of a watershed, draining to a specific impaired water. For discharges to
watersheds affected by a TMDL, coverage under this permit may depend on the facility
demonstrating it does not have reasonable potential to violate applicable water quality standards
for those pollutants as a result of discharges. If DWQ determines that discharges have reasonable
potential to cause water quality standard violations, the facility shall apply for an individual permit 180
days prior to the expiration date of this General Permit Once that individual permit is effective, the facility
will no longer have coverage under this General Permit.
During the period beginning on the effective date of the permit and lasting until expiration, the permittee is
authorized to discharge stormwater associated with industrial activity. Such discharges shall be controlled,
limited, and monitored as specified in this permit
Part I Page 1 of 2

Permit No. NCG120000
SECTION B: PERMITTED ACTIVITIES
Until coverage under this permit expires or is modified or revoked, the permittee is authorized to discharge
stormwater, to the surface waters of North Carolina or to a separate storm sewer system, which has been
adequately treated and managed in accordance with the terms and conditions of this General Permit.
Any other point source discharge to surface waters of the state is prohibited unless it is an allowable non-
stormwater discharge or is covered by another permit, authorization, or approval. The discharges
authorized by this General Permit shall not cause or contribute to violations of Water Quality
Standards.
Where wetlands are located on or nearby landfilling operations, discharges authorized by this permit and
site operations must meet applicable wetland standards, as recorded in 15A NCAC 2B .0230 and .0231, and
water quality certification requirements as outlined in 15A NCAC 2H .0500.
This permit does not relieve the permittee from responsibility for compliance with any other applicable
federal, state, or local law, rule, standard, ordinance, order, judgment, or decree.

PART II MONITORING, CONTROLS, AND LIMITATIONS FOR PERMITTED DISCHARGES
SECTION A: LIMITATIONS AND CONTROLS FOR STORMWATER DISCHARGES
During the period beginning on the effective date of the Certificate of Coverage and lasting until expiration
of the General Permit, the permittee is authorized to discharge stormwater. Such discharges shall be
controlled, limited, and monitored as specified below:
1. Prior to commencement of land disturbing activities, the permittee shall submit for approval a
Sedimentation and Erosion Control Plan (plan) to the Department of Environment and Natural
Resources, Division of Energy, Mineral, and Land Resources, or an approved local program,
pursuant to the requirements of NC G.S.113A-54.1 and in conformity with the rules adopted by the
Sedimentation and Erosion Control Commission.
2. The permittee shall implement the approved plan. The approved plan is a requirement or condition
of this General Permit. Deviation from the approved plan, or approved amendment to the plan,
shall constitute a violation of the terms and conditions of this General Permit. A signed copy of the
approved plan shall be maintained on the site at all times.
3. Prior to constructing or operating a landfill the permittee shall obtain a permit for a sanitary landfill
from the N.C. Department of Environment and Natural Resources, Division of Waste Management,
pursuant to the requirements of NC G.S.130A - 294 and in conformity with the rules adopted in 15A
North Carolina Administrative Code, Subchapter 13B Section .0500 or Section .1600. The landfill
permit is a requirement or condition of this General Permit. Deviation from the landfill permit, or
approved amendment or revision of the landfill permit, shall constitute a violation of the terms and
conditions of this General Permit. A signed copy of the landfill permit shall be maintained on the
site at all times.
4. Secondary Containment Requirements and Records. Secondary containment is required for: bulk
storage, of liquid materigis including o um prgducts sJorage in any amountSection 313 of
Tide III of the SuperfundAmendmJents and Reauthorization Act Sf ARA] waterpdQfity chemicals:
and stoEage in any amount of hazardous substancesin order to prevent leaks and spills from
contaminating stormwater runoff. A table or summary of all such tanks and stored materials and
their associated secondary containment areas shall be maintained. If the secondary containment
devices are connected to stormwater conveyance systems, the connection shall be controlled by
manually activated valves or other similar devices, which shall be secured closed with a locking
mechanism. Any stormwater that accumulates in the containment area shall be at a minimum
visually observed for color, foam, outfall staining, visible sheens and dry weather flow, prior to
release of the accumulated stormwater. Accumulated stormwater shall be released if found to be
uncontaminated by any material. Records documenting the individual making the observation, the
description of the accumulated stormwater, and the date and time of the release shall be kept for a
period of five (5) years. For facilities subject to a federal oil Spill Prevention, Control, and
Countermeasure Plan, facility compliance with any portion of the SPCC plan fully consistent with
the requirements of this permit maybe used to demonstrate compliance with this permit.
5. Equipment utilized during the land disturbing or landfill operational activities on a site shall be
operated and maintained in such a manner as to prevent potential or actual pollution of the surface
or ground waters of the state. Fuels, lubricants, coolants, and hydraulic fluids, other petroleum
products, and spent fluids shall be disposed of in a manner so as not to enter the waters, surface or
ground, of the state and in accordance with applicable state and federal disposal regulations. Any
Part 11 Page 1 of 6

Permit No. NCG120000
spilled fluids shall be cleaned up to the extent practicable and disposed of in a manner so as not to
allow their entry into the waters, surface or ground, of the state.
SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All analytical
monitoring shall be performed during a measureable storm event at each stormwater discharge outfall
(SDO). Only SDOs having stormwater discharges associated with industrial activity must be sampled. See
Definitions.
A measurable storm event is a storm event that results in an actual discharge from the permitted
site outfall. The previous measurable storm event must have been at least 72 hours prior. The 72-
hour storm interval does not apply if the permittee is able to document that a shorter interval is
representative for local storm events during the sampling period, and the permittee obtains
approval from the local DWQ Regional Office. See Definitions.

2 Sample collection must begin within the first 30 minutes of discharge and continue to all outfalls until completed.
3 Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless
representative outfall status (ROS) has been granted by DWQ. A copy of the DWQ letter granting ROS must be kept
on site. DWQ's ROS letter remains in effect through the subsequent reissuance of this permit and as long as the
pertinent site conditions and operations remain unchanged, unless the ROS letter provides for other conditions or
duration.
4 For each sampled measureable storm event the total precipitation must be recorded from an on -site rain gauge.
(Where isolated sites are unmanned far extended periods, a local rain gauge reading may be substituted for an on -site
gauge, upon prior DWQ written approval.)
The permittee shall complete the analytical samplings in accordance with the schedule specified in Table 2
below, unless adverse weather conditions prevent sample collection (see Definitions) Inability to sample
because of adverse weather conditions must be recorded on the Discharge Monitoring Report, along with a
description of the adverse conditions and their duration. Sampling is not required outside of the facility's
normal operating hours.
A minimum of 60 days must separate Period 1 and Period 2 sample dates unless monthly monitoring
has been instituted via other requirements of this permit. The permittee must report the results of every
discharge sample taken within the monitoring period (see Part III, Section E).
Failure to monitor semi-annually per permit terms may result in the Division requiring monthly
monitoring for all parameters for a specified time period. "No discharge" from an outfall or inability to
collect a sample because of adverse weather conditions during a monitoring period, for example, does not
constitute failure to monitor, as long as it is properly reported.

via other permit requirements.)
2 if no discharge occurs during the sampling period, the permittee must submit a monitoring report indicating "No
Floyd' within 30 days of the end of the sampling period.
The permittee shall compare monitoring results to the benchmark values in Table 3. The benchmark values
are not permit limits but should be used as guidelines for the permittee's response actions to control the
discharge of pollutants in site stormwater. Exceedances of benchmark values require the permittee to increase
monitoring, increase management actions, increase record keeping, and/or install stormwater Best
Management Practices (BMPs) in a tiered program.

Each separate parameter benchmark exceedance triggers a separate tiered response for that parameter at that
outfall. See the descriptions of Tier One, Tier Two, and Tier Three response actions below. In the event that
DWQ releases the permittee from continued monthly monitoring under Tier Three, DWQ's release letter
remains in effect through the subsequent reissuance of this permit unless the release letter provides for other
conditions or duration.

Permit No. NCG120000
Tier One
If: The first valid sampling results are above a benchmark value, or outside the benchmark range, for
anv narameter at anv outfall:
Then: The permittee shall:
1. Conduct a stormwater management inspection of the facility within two weeks of receiving
sampling results.
2. Identify and evaluate possible causes of the benchmark value exceedence.
3. Identify the potential, and select the specific: source controls, operational controls, or physical
improvements to reduce concentrations of the parameters of concern.
4. Implement the selected actions within two months of the inspection.
5. Maintain an on -site record of each instance of a Tier One response. Include the date and value
of the benchmark exceedence, the inspection date, the personnel conducting the inspection,
the selected actions, and the date the selected actions were
Tier Two _
If: During the term of this permit, the sampling results are above the benchmark values, or outside
the benchmark range, for any specific parameter at a specific discharge outfall two times in a row;
; Then: The permittee shall:
1. Repeat all the required actions outlined above in Tier One.
2. Immediately institute monthly monitoring for allarameters. Conduct monthly monitoring at
every outfall where a sampling result exceeded the benchmark value for two consecutive
samples. Monthly (analytical and qualitative) monitoring shall continue until three
consecutive sample results are below the benchmark values, or within the benchmark range.
3. Submit a monthly monitoring report indicating "No Plow" if no discharge occurs during the
sampling period.
4. Maintain a record of the Tier Two response and monitoring results on site.
Tier Three
During the term of this permit, if the valid sampling results required for the permit monitoring
periods exceed the benchmark value for any specific parameter at any specific outfall on four
occasions, the permittee shall notify the DWQ Regional Office Surface Water Supervisor in writing
within 30 days of receipt of the fourth analytical results. DWQ may, but is riot limited to:
• require that the permittee revise, increase, or decrease the monitoring frequency for some
or all parameters;
• rescind coverage under the General Permit, and require that the permittee apply for an
individual stormwater discharge permit;
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures;
• require the permittee to perform upstream and downstream monitoring to characterize
impacts on receiving waters.

Permit No. NCG120000
Failure to monitor semi-annually per permit terms may result in the Division requiring monthly
monitoring for a specified time period. "No discharge" from an outfall or inability to collect a sample
because of adverse weather conditions during a monitoring period, for example, does not constitute failure
to monitor, as long as it is properly reported.
SECTION D: QUALITATIVE MONITORING AND VISUAL INSPECTION REQUIREMENTS
,Qualitative monitoring shall be performed twice per year and concurrent with the analytical monitoring
requirements in Part If Sections B and C for the characteristics listed in Table 6. Qualitative monitoring is
for the purpose of quickly evaluating the effectiveness of the stormwater controls. No analytical tests are
required. The permittee shall maintain a written record of the qualitative monitoring events on site.

Fgotngte 1: Qualitative monitoring shall be performed at each stormwater discharge outfall (00) regardless of
representative outfall status (ROS) unless ROS has been granted specifically for qualitative monitoring. A copy of
DWQ's letter granting ROS must be kept on site. DWQ's ROS letter remains in effect through the subsequent
reissuance of this permit and as long as the pertinent site conditions and operations remain unchanged, unless the
ROS letter provides for other conditions or duration.
Visual inspections shall be conducted to ensure that all stormwater controls, including all sedimentation
and erosion controls, are intact, in good repair, fully functional, and are otherwise being properly
implemented. Inspections shall be conducted at least once every seven calendar days, and within 24 hours
after any storm event of greater than 0.5 inches of rain per 24 hour period. The permittee shall maintain a
written record of each visual inspection on site.
In the event an atypical condition is noted at a stormwater discharge outfall, the permittee shall maintain on -
site records of both the suspected cause of the condition and the corrective actions taken.
If the permittee's qualitative monitoring or visual inspections indicate that existing stormwater controls are
ineffective, or that significant stormwater contamination is a recurring condition, the permittee shall
investigate potential causes, evaluate the feasibility of corrective actions, and implement feasible corrective
actions within 60 days. A written record of the permittee's investigation, evaluation, and response actions
shall be kept on site. Records related to qualitative monitoring and visual inspections need only be
submitted to DWQ upon the Division's specific request for those records.

1. Act
See Clean Water Act
2. Adverse Weather
Adverse conditions are those that are dangerous or create inaccessibility for personnel, such as local flooding,
high winds, or electrical storms, or situations that otherwise make sampling impractical. When adverse
weather conditions prevent the collection of samples during the sample period, the permittee must take a
substitute sample or perform a visual assessment during the next qualifying storm event Documentation of
an adverse event (with date, time and written narrative) and the rationale must be included with your
records. Adverse weather does not exempt the permittee from having to file a monitoring report in
accordance with the sampling schedule. Adverse events and failures to monitor must also be explained and
reported on the relevant DMR.

Permit NCG120000
i Technical Bulletin for NC6120000, Landfills Last revised 10/25/2012
What is regulated by this General Permit?
This General Permit regulates stormwater discharaes from landfills (including construction and demolition
landfills) and associated on -site activities.
What does my DWQ stormwater permit require me to do?
✓ Implement your approved Sedimentation and Erosion Control Plan (Part 11, Section A).
✓ implement your solid waste permit from the Division of Waste Management (Part 11, Section A).
✓Install secondary containment for bulk storage of liquids, including petroleum products (Partll, Section A).
✓Conduct semi-annual testing of the stormwater discharges, and report results to DWQ (Part l! Sections B and C).
✓Conduct semi-annual visual monitoring of stormwater discharge flows for the characteristics listed in the permit,
and keep the records of the visual monitoring on your site (Part 11, Section D).
✓Inspect your sediment and erosion control measures and your stormwater control measures weekly, and after
every 1/2" rain. Keep the records of the inspections on your site (Port 11, Section D).
-'Respond to monitoring results that exceed the numerical benchmarks with management actions to reduce the
level of pollutants in the stormwater discharges. Note that the numerical benchmarks should be considered as
'action levels', rather than permit limits, and so would not alone generate permit violations. (Part 1l, Sections
B, C, and D).
Why?
-'The General Permit seeks to reduce pollution in rainfall runoff from landfills by requiring site managers to be
aware of, and to reduce, contamination in stormwater runoff.
✓ Federal and state laws and water regulations require the reduction of pollution in stormwater from landfills.
✓Those laws and regulations reflect the public's support for clean natural waters in our state and nation.
What has changed since the last renewal in 2007?
• Although they were previously subject to water quality regulation according to federal rule, the General Permit
now specifically clarifies that construction and demolition landfills may be regulated by this permit.
• The permittee may now sample discharges from any measureable storm event, rather than from a representative
event. This change should make it easier to obtain a sample from a qualifying rain event.
• The permit text now clarifies that failure to sample due to adverse weather, or due to no discharge during the nor-
mal monitoring period, may be excused. However, the permit now provides that additional monthly monitoring
for unexcused failures to monitor may be required by DWQ.
• The permit now provides that sampling is not required outside of the facility s normal operating hours.
• Visual monitoring of the discharge flows for the characteristics listed in the permit has been reduced in frequency
from weekly to semi-annual. However, inspections of the sedimentation and erosion control measures have been
retained as a weekly obligation.
• The permit text now clarifies that if DWQ relieves the permittee from monthly monitoring under Tier 2, that relief
would continue into subsequent permit renewals, unless DWQ's relief letter provides otherwise.
• Vehicle Maintenance Areas (VMA) will be monitored for Total Petroleum Hydrocarbons (TPH) rather than Oil &
Grease (O&G).
• VMA monitoring is now triggered by the total oil usage for motor oil plus hydraulic oil. The trigger remains at a
total of 55 gallons per month, average_
• A lower TSS benchmark of 50 mg/L applies for discharges to especially protected water classifications_

Frequently Asked Questions
Do I have to monitor all outfalls?
Yes. However, you may request ROS
(Representative Outfall Status). If ROS is
approved, this status allows analytical
monitoring at fewer outfalls. To request
ROS, submit a ROS Request Form SWU-
ROS (from our website) to the DWQ
Regional Office.
What if I can't collect a storm -
water discharge in 30 minutes?
When distances separate multiple out -
falls and preclude collection within 30
minutes of each discharge event, begin
collection within 30 minutes and then
continue until all outfalls are sampled.
Documentation of the site circum-
stances must be kept with the sampling
records on site.
Can 1 take more samples than
is required by my permit?
Yes. The permittee may take multiple
samples at any time while under per-
mit coverage. The permittee may find
the extra sampling useful to quickly
identify causes of benchmark ex-
ceedances. All sampling for the permit
parameters must be reported to DWQ
on the DMR forms.
What if I can't sample because
of bad weather?
Adverse weather is dangerous or it
may limit access for sampling person-
nel. Your documentation of adverse
weather and the reasons for not sam-
pling must be included in your on -site
records. A substitute sample may be
taken during the next qualifying storm
event.
What if 1 don't address visual
monitoring problems?
If you do not respond to problems seen
in visual monitoring, DWQ may require
that you increase the visual monitoring
frequency, apply for an individual per-
mit, implement in -stream monitoring,
install or modify structural stormwater
controls, or implement other controls.
What if I forget to monitor?
DWQ may require monthly monitoring
for a specified time period.
Why did you replace Oil &
Grease with TPH in VM areas?
The TPH test only targets chemicals de-
rived from crude oil. The Oil & Grease
(O&G) test recovers fats from animal &
vegetable sources and chemicals from
crude oil. Because TPH is more specific,
it is a better parameter for vehicle main-
tenance areas. The TPH method we are
specifying is EPA 1664A (SGT-HEM). It is
important to note that DWQ is not speci-
fying the more expensive Gas Chromato-
graph (GC) TPH method. DWQ found lab
costs for EPA 1664A (SGT-HEM) to be
comparable to O&G test costs. To test
these parameters in stormwater labs
must perform this test in accordance
with EPA procedures, but do not need to
be certified. Note: A lower benchmark
applies for TPH: 15 mg/I (not 30 mg/1).
Why are there two benchmark
values for TSS?
The 100 mg/L benchmark applies to
most rivers, lakes, and creeks in North
Carolina. However, some other waters
must receive special protection under
North Carolina water quality rules, and
in this permit discharges to them are
Subject to the more protective bench-
mark of 50 mg/L. Those waters classified
as Trout Waters, High Quality Waters,
Outstanding Resource Waters, and Pri-
mary Nursery Areas receive this extra
protection.
Where and when do I send the
monitoring reports?
See your permit text, Part lil, Section E.
Who can help me?
Division of Water Quality (DWQ) Offices:
Must I use a North Carolina
certified laboratory?
No. North Carolina water quality rules
do not require that analyses of storm -
water be accomplished by a certified
facility. Please note however, federal
rules at 40CFR136 do require that test-
ing for this permit be by EPA -approved
lab methods. Analysis by a North Caro-
lina certified lab is often the easiest
way to insure compliance with federal
rules.
Note that pH is a special case, and
must be measured within 15 minutes
of the sample recovery. You must ei-
ther train on -site staff to conduct pH
testing, or contract with commercial
services to test pH in accordance with
EPA field testing methods.
Who inspects me, and for
what?
Staff from the DWQ Regional Offices
shown below will inspect your facility.
They will typically ask to see your Sedi-
mentation and Erosion Control Plan to
see that it is being fully impie mented.
They will typically ask to see your re-
cent monitoring results. They will typi-
cally tour the facility with a focus on
the stormwater discharge outfalls and
on your general housekeeping as a way
to assess the potential for polluted
stormwater discharges. Our staff will
always follow up their Compliance
Evaluation inspection with a summary
letter to you, restating their findings
and, if necessary indicating whether
enforcement action will be considered
in response to those findings.

Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event." However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains annroval from the local DWO Regional Office.

Was this a "Representative Storm Event" or "Measureable Storm Event" as defined by the permit?
(See information below.)
Yes ❑ No
Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event' (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event' or during a "measureable storm event" However,
some permits do not have this requirement Please refer to these definitions, if applicable.
A "representative storm event' is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
A "measurable storm event' is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office.
By this signature, I certify that this report is accurate and complete to the best of my knowledge:
