Dear Mr. Holding:
Natural Resources
John E. Skvarla, III
Secretary
On June 19, 2013, Autumn Romanski, of the Division of Water Quality (DWQ), Raleigh Regional Office,
performed a stormwater compliance evaluation inspection of the Thomas Concrete Plant in Wake Forest. Mr.
Brian Westfall, the Plant Manager on the site had a thorough knowledge of the permit and his implementation of
Stormwater Best Management Practices was evident. The facility was in compliance with the permit the day of
the inspection. Thank you for your staffs time, assistance and cooperation. Inspection findings are listed
below.

Indust ;and Site Descn tion �, *-
Thomas Concrete mixes concrete on -site for delivery to construction sites, road projects, and commercial
customers. Stormwater runoff and process wastewater generated at such facilities is regulated by General
Permit NCG140000. DWQ has therefore issued Thomas Concrete certificate of coverage, NCG140350, which
became effective on July 1, 2011 and expires on June 30, 2016.
The facility has plugged the stormwater collection trough, such that stormwater no longer direct discharges from
the trough. The facility has also re-routed stormwater from a prior stormwater outfall to the collection trough,
thus eliminating a stormwater outlet. The facility is deemed permitted to re -use the stormwater and has
instituted re -use of the stormwater from the trough, such that discharge would be only be in the event that the
volume of water stored in the trough exceeded the capacity of the trough. The plant monitors the trough for
pump out, maintenance, and cleaning as needed.

The facility keeps excellent records and was in compliance with permit requirements. The Stormwater Pollution
Prevention Plan was reviewed, and the facility has several BMP's implemented that aid in pollution prevention
as evidenced by the site conditions.

The Analytical monitoring was completed quarterly as required by the permit. The sample results provided in
2012-2013 were sampled from the stormwater trough (retention basin) and slightly elevated in Total Suspended
Solids (TSS), but the samples were not required since the trough was plugged, not overflowing, and not
discharging off the property. In the future, please note a sample should only be taken if the stormwater is
allowed to discharge off the property and should be sampled where the stormwater is discharging off the
property when possible. The monitoring data did not show any significant findings to be addressed.

The facility has one outfall UT to Neuse River. The stormwater trough (retention basin) was below the overflow
and no discharge was observed the day of the inspection. The outfall was clear with no signs of concrete, spoil,
or aggregate.
It is our goal to insure the quality of the surface waters of this State.

Comment: Analytical Monitoring results were reported and TSS readings were
elevated in 2012 and 2013. The site contains a trough (retention basin) that stores the
stormwater. The stormwater basin is pumped out and water is re -used on -site.
The sample was obtained by sampling the stormwater in the trough, since no
stormwater was discharging to the BMP Dry retention basin from the trough. This likely
led to elevated values TSS. (You may expect poorer settling performance of the
stormwater in the trough in a rain event). If there is no discharge from the trough,
please do not sample, as sampling is intended to capture the stormwater discharge as it
leaves the permittee's property.
PLEASE record no flow, if there is no discharge. IF the trough discharges at any time
during the permit monitoring periods, then please sample the discharge as it leaves the
plant's property.

Comment: One outfall 001, collects all the stormwater drainage at the site. The outfall
has been re -constructed as a retention basin and the water is pumped out of the basin
and reused at the site. The site no longer discharges direct off the property, but the
stormwater retention basin could overflow and (sheetflow) off the property if stormwater
exceeds retention basin capacity.

Summary
This facility submitted a Notice of Intent to be covered under General Permit NCG140000
(Ready Mix Concrete). This facility is a concrete ready mix plant. The
stormwater/wastewater discharge drains to an unnamed tributary (UT) to the Neuse
River, a Class WS-IV NSW stream in the Neuse River Basin. This facility is located in
Wake County, handled by the Raleigh Regional Office.
Application review
a) The permit application has been signed and sufficiently completed. No;
consultant signed the application.
b) The SIC code accurately describes this facility's activities and is covered by this
general permit. Yes. SIC: 3273 (Ready -mix Concrete)
c) Does this facility have other permits? No.
d) Hazardous Waste Activities? No.
e) Stormwater BMPs and Wastewater discharge:
This facility has a recycle pond and settling basin (with multiple cells). Details
regarding volume, retention time, and surface area of stormwater treatment
facilities were not available for the application (see page 5 of the NOI);
performance of current treatment facilities and any proposed modifications will
be evaluated during development of the Storm Water Pollution Prevention Plan.
Process wastewater from vehicle and equipment cleaning, and raw stockpile
material wetting is routed to the settling pond. Mixing drum washout water is
purged directly into the first settling pond cell. The application indicated "purge
material and water from the mix plant" is transported via truck to the fast settling
pond cell (covered in NCG14?). Per contact (Consultant Bill Rice, F&R), about
twice a day, mix plant material (roughly 2.5-3 cu. ft. of material in 500 gal. water)
is dropped into first settling basin, which subsequently drains to the recycle
pond —essentially very similar to mix drum clean -out water. Whether it can be
called mix drum washout or not, it should be covered under "process wastewater
associated with Recycle Systems" in the NCG14 Permit. Facility recycles most
water at the site via the recycle pond system.

Hi Bethany,
In response to your question regarding plant mix drum purged materials at the Thomas Concrete Wake Forest
plant, I write the following:
According to Mr. Brian Westfall, Plant Manager for Thomas Concrete's Wake Forest plant, the plant mix drum is
purged up to twice a day during busy periods, dispensing an average of 3.5 cubic feet of concrete solids into truck
mix drums that are driven over and disposed of in the first cell of the plant's recycling/settling pond. The fines and
suspended solids are then subsequently settled out with each successive settling pond cell, and the water is
recycled into batch mixes.
Have a good night,

Thomas Concrete - Wake Forest Plant
The Division of Water Quality has reviewed your request for a new NPDES General Permit
received on December 28, 2004. We are requesting additional information (in this case, a
revised application) to address the following items:
❑ Application must be signed by a company official, per NCAC 15A 02H .106.
❑ Please provide more information regarding "purged material and water from the mix plant
[that] is dropped into a truck and driven to the first settling pond cell." (Question 13.) In
addition to stormwater discharge, General Stormwater Permit NCG140000 covers (1) vehicle
and equipment cleaning, (2) recycle system overflow, (3) raw material stockpile wetting, and
(4) mixing drum washout discharges; however, whether 'mix plant purge material and water'
falls into one of these categories is not clear. Please refer to NCG140000 (accessible from
our website: http://h2o.enr.state.nc.us/su/Forms Documents.htm#stormwaterGP) for the
specific types of discharge covered by the general permit.
The original application is attached. Please return the revised application and information
requested above by March 1, 2005 so that we may continue processing your request. To avoid
confusion regarding payment for this NOI application and to preserve the assigned permit
number in our tracking system, we are treating this as an additional information request, rather
than a return of your application package.

Response to 13.) Continued from Page 2 of 4
If yes to any of the above, please describe the type of process used to treat and/or recycle the process
wastewater. Give design specifics (i.e. design volume, retention time, surface area, etc.).
• Vehicle and Equipment Cleaning. Currently process water flows from vehicle washing are routed into the settling
pond via gravity flow. There is no other form of on -site equipment cleaning that that occurs on a regular basis.
• Wetting of Raw Materials. The only raw material stockpile that requires wetting is the light -weight aggregate
stockpile (shown on the attached figure). Run off from this pile runs onto the lot and into the perimeter curb drainage
channels, ultimately ending into the aforementioned on -site settling basin for catching fines from surface flows off of
the plant lot .
• Mixing Drum Cleaning. Truck mix drums are washed out and purged directly into the first settling pond cell where
their suspended solids settle out as waters slowly travel into the successive pond cells via gravity flow. The mix plant
drum is purged up to twice a day, depending on business volume. Purged material and water from the mix plant is
dropped into a truck and driven to the first settling pond cell.
• Design Volume, Retention Time, Surface Area, Etc. Currently, the subject facility is in the process of being
studied for purposes of developing a Storm Water Pollution Prevention Plan (SP3). At this current time, no data exists
that would sufficiently respond to the questions regarding volume, retention time, and surface area of the existing
stormwater treatment facilities. Performance of the existing and any proposed BMPs will be discussed with the DWo
and Thomas Concrete during the development of the forthcoming SP3.

Compliance Schedule Correction
Wake
Dear Wayne Woodlief:
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 11, 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 11, Section A: Final Limitations and Controls
for Stormwater Discharges.
If you have any questions concerning this matter please contact Aisha Lau at

Subject: NPDES Stormwater General Permits Status for
Wake County, North Carolina Solid Waste Facilities
COC Numbers NCG120020 and 120021
Dear Mrs. Manuel:
,`UG 1 5 2003
In 2002, Wake County Solid Waste Management Division retained Camp Dresser & McKee
(CDM) in order to renew NPDES Stormwater General Permits for two solid waste
management facilities. These two facilities - the North Wake Municipal Solid Waste Facility
located on Durant Road in north Raleigh and Feltonsville Landfill located on Old Smithfield
Road in Holly Springs - have been provided coverage by your office through Stormwater
General Permit Number 120000, which was renewed for a five year period on August 23,
2002. These two facilities are identified as COC Numbers 120020 and 120021 on the renewal
letters of that date.
In April 2003, Wake County was notified that these two facilities had been granted new
NPDES General Permits under General PernutNCG080000. Ina letter dated June 9, 2003,
CDM informed the Division of Water Quality (DWQ) that the new Stormwater General
Permits issued on April 25, 2003 should not have been issued for these two facilities since
active Stormwater General Permits were in place. The DWQ informed CDM, in a letter dated
June 23, 2003 (attached), that the NPDES General Permits NCG080672 and NCG080673 were
rescinded. The letter implied that this rescission was based on the assumption that activities
at the sites, covered under the general permits, had ceased or been eliminated.
The intent of this letter is to inform the DWQ that these two facilities are currently active and
complying with the requirements outlined in the previously renewed Stormwater General
Permits COC Numbers 120020 and 120021 issued in August 2002. Please let us know if this is
in conflict with the DWQ's understanding of the situation.

Rescission of NPDES Permit
Wake County Solid Waste Management Facilities
Permit Numbers NCGO80672 & NCGO80673
Wake County
It is the understanding of the Division that the subject facility is no longer in need of the subject
stormwater permits. In accordance with this information, NPDES General Permits NCG080672 and
NCG080673 are rescinded, effectively immediately.
Please be advised that this permit rescission is based wholly upon the activities which would require
general permit coverage at the site have ceased or been eliminated. Division staff has not visited the site
to obtain independent verification. Operating a treatment facility, discharging wastewater or discharging
stormwater to waters of the State without a valid NPDES Permit will subject the responsible party to a
civil penalty of up to $25,000 per day. Enforcement action will be certain for persons that have
voluntarily relinquished permit coverage when, in fact, continuing permit coverage was necessary. If, in
retrospect, you feel the site still requires permit coverage, you should notify this office immediately.
Furthermore, if in the future you wish to again discharge to the State's surface waters, you must first
apply for and receive a new NPDES Permit.
If you have questions about this matter, please contact Vanessa Manuel at [phone], extension 532
or the Water Quality staff in the Raleigh Regional Office at [phone].

Dear Mr. Gilkerson:

Alan W. Klimek, P.E. Director
Division of Water Quality
A review of applications for coverage under NCG120000 for stormwater discharges from the Hwy 55 C & D Landfill, on
Old Smithfield Road, Apex, Wake County, which was received in this office last summer has been completed. After
review of this matter we have determined that an NPDES stormwater permit is not required for the landfill. The only
landfills that are categorically subject to NPDES stormwater permits are those landfills that receive waste material from
Industrial Activities (mostly manufacturing firms). LCID landfills do not meet this description and are thus not subject to
the requirement to categorically have a permit.
Therefore, your NOI and fee check for $80 are being returned to you without further action. It will not be necessary to
have a stormwater NPDES permit for this facility at this time.
If you have any questions or need further information, please contact me at 733-5083 ext 548 or [e-mail]

Rescission of NPDES Permit
Wake County Solid Waste Management Facilities
Permit Numbers NCG080672 & NCG080673
Wake County
It is the understanding of the Division that the subject facility is no longer in need of the subject
stormwater permits. In accordance with this information, NPDES General Permits NCG080672 and
NCGO80673 are rescinded, effectively immediately.
Please be advised that this permit rescission is based wholly upon the activities which would require
general permit coverage at the site have ceased or been eliminated. Division staff has not visited the site
to obtain independent verification. Operating a treatment facility, discharging wastewater or discharging
stormwater to waters of the State without a valid NPDES Permit will subject the responsible party to a
civil penalty of up to $25,000 per day. Enforcement action will be certain for persons that have
voluntarily relinquished permit coverage when, in fact, continuing permit coverage was necessary. If, in
retrospect, you feel the site still requires peunit coverage, you should notify this office immediately.
Furthermore, if in the future you wish to again discharge to the State's surface waters, you must first
apply for and receive a new NPDES Permit.
If you have questions about this matter, please contact Vanessa Manuel at [phone], extension 532
or the Water Quality staff in the Raleigh Regional Office at [phone].
Sincerely,

— r
Permit NCG120000
I Technical Bulletin for NCG120000. Landfills Last Revised 10/25/2012
What is regulated by this General Permit?
This General Permit regulates stormwater discharges 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 (Part 11, Section A).
✓Conduct semi-annual testing of the stormwater discharges, and report results to DWQ (Part ll Sections 8 and Q.
-'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 ll, 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 (Part Il, 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 Il, Sections
8, C, and D).
✓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.
• 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 meosureable 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 (0&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 1 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 I 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 samplipg 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 I 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
(0&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 Chromoto-
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 I11, Section E.

Mooresville Office......... [phone]
Raleigh Olfcg}...,,........ (919) 791y4200
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 implemented.
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.

Permit No. NCG120000
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 N01 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.

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 materials including petroleum products; storage in any amount of Section 313 of
Title III of the Superfund Amendments and Reauthorization Act (SARA) water priority chemicals;
and storage in any amount of hazardous substances, in 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 may be 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.

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 for 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
Flow" 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 parameter 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.
S. 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 implemented.
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 all parameters. 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 Flow" 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 not 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.

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 11 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.

Footnote 1: Qualitative monitoring shall be performed at each stormwater discharge outfall (SDO) 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 recordof 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.

SECTION C: OPERATION AND MAINTENANCE OF POLLUTION CONTROLS
Proper Operation and Maintenance
The permittee shall at all times properly operate and maintain all facilities and systems of treatment and
control (and related appurtenances) which are installed or used by the permittee to achieve compliance with
the conditions of this permit. Proper operation and maintenance also includes adequate laboratory controls
and appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary
facilities or similar systems which are installed by a permittee only when the operation is necessary to
achieve compliance with the conditions of this permit [40 CFR 122.41(e)].
2. Need to Halt or Reduce Not a Defense
It shall not be a defense for a permittee in an enforcement action that it would have been necessary to halt or
reduce the permitted activity in order to maintain compliance with the condition of this general permit [40
CFR 122.41(c)].
3. Bypassing of Stormwater Control Facilities
Bypass is prohibited and the Director may take enforcement action against a permittee for bypass unless:
a. Bypass was unavoidable to prevent loss of life, personal injury or severe property damage; and
b. There were no feasible alternatives to the bypass, such as the use of auxiliary control facilities, retention
of stormwater or maintenance during normal periods of equipment downtime or dry weather. This
condition is not satisfied if adequate backup controls should have been installed in the exercise of
reasonable engineering judgment to prevent a bypass which occurred during normal periods of
equipment downtime or preventive maintenance; and
