Technical Bulletin for General Stormwater Permit NCG2.10000
Technical Bulletin for NCG210000. Volume V Revised $tt12013 1
What activities are covered by this general permit?
NCG210000 allows st.ormwater discharges associated with establishments primarily engaged in manufacturing
Timber Products [standard industrial classification (SIC) 24] and activities deemed by DEINILK to be similar in
the process and/or the exposure of ra«• materials, products, by-products, or Write materials. In 2011, the general
permit was modified to cover discharges from Wood Chip Mills. which ,vere previously excluded.
Excluded: Wood Kitchen Cabinets [SIC 2434], % ood Preserving [SIC 2491), and Logging [SIC 24111.
What are the key permit requirements?
> Implernent a Storrnwater Pollution Prevention Plan (SPIT) (Part 11, Section A).
> Provide secondary containment for all bulk storage of liquid materials (Part 11, Section A, 2.(b)).
> Perform and document qualitative monitoring during a measurable storm event (Part 11, Section C).
> Perform analytical monitoring twice per year if storing exposed accumulations of sawdust, wood chips, bark,
mulch, or like materials on site for more than seven (7) days, and submit the results on the monitoring report
forms provided with the permit (Part, 11, Section B).
What has changed since the last renewal?
Some of the major changes since the last renewal include:
> Refinements and clarifications to the SPPP requirements; refer to Part 11, Section A.
> Provisions to allow permittees to petition the DE1%,1LR Regional Office Supervisor for relief frorn monitoring.
> It should be easier for monitoring to take place during a measurable storm event (new term) rather than a
representative storm event (old term); refer to Part 11, Section 13.
> The requirement for twice per year monitoring of pl-1 has been eliminated; refer to Part. I I, Section B.
> The TSS benchmark has been lowered to 50 mgl1, for discharges into some especially sensitive waters; refer to
Part 1I, Section B,
> The tiered response structure has been modified to allow the 17H:1'IL.R Regional Office Supervisor to grant
relief from 'Pier Two monthly monitoring; refer to Part It, Section 13.
What are BMPs and why are they important?
The SPPP should include "Best _1lanagement Practices" (13ti11 Ps) to control discharge of pollutants from a facility's
stormwater outfalls. B.Ws include a variety of things that help minimize the potential for pollutants to get into
the storinwater draining from a facility. 'There are different types of 131Ng11`s:
.Von -structural (practices or activities) BMI's include:
> Eliminating exposure of materials and equipment wherever possible by moving there to indoor locations.
> Practicing good housekeeping on -site. Handle and store materials nt the facility in an orderly fashion.
> Exchanging hazardous materials for non -hazardous ones wherever possible.
> Establishing routine leak & maintenance checks to minimize chance of spills. Clean up spills immediately.
> Establishing bulk storage tank protocols that minimize the risk of spills during loading and unloading.
> Store used pallets and process waste dumpsters inside or under roof so water can't flow on or around them.
Structural (equiprnent or devices) I3Ws include:
> Containment dikes around the loading areas of bulk liquid storage containers.
> Changing painting operations from liquid systems to powdered systems that do not generate solvent waste.
> Roofs and secondary containment around materials stored outside so that stormwater cannot contact them.

TECHNICAL BULLETIN FOR GENERAL STORMWATER PERMIT NCG210000
Frequently Asked Questions
Could l be exempted from an
NPDES stormwater permit?
Possibly. A facility with industrial
activity subject, to the NI'DES
Stormwater regulations that elimi-
nates all potential stormwater expo-
sure may be eligible for a No Expo-
srire Exclusion from a permit. A
Facility that meets this condition
may submit a No Exposure Certifi-
cation application (see our website
below).
What if I sell my business, or the
name changes?
'['his change is a minor modification
and requires the I)irector's action to
transfer permit coverage. Complete
the NamelOwncrship Change Form
S%VU-239, is available on our web -
site:

Do I have to monitor all the
outfalls?
Yes. 1-lowever, ,you may request
Representative Outfrill Status
(ROS). If approved, this status al-
lows analytical monitoring at fewer
outfalls, To request ROS, submit a
ROS Request Form SWU-ROS to the
I)]'.NlLR Regional Office. The form
is available on our website (see
above).
Asheville Office
Fayetteville Office
Mooresville Office
Raleigh Office
Online resources
Does a certified lab need to
analyze my samples?
Monitoring under all NI'DES per-
mits must be conducted in accor-
dance with test procedures ap-
proved under federal regulations in
40 CFR §13G. Labs certified by
North Carolina perform analysis in
accordance with those procedures.
N.C. certification requirements do
not apply to slorinivater only dis-
charges, but data gathered under
an NPDDES permit, must conform to
federal requirements. Using a cer-
tified lab is one way to ensure com-
pliance. A list, of certified labs is
available at: hu LE
portal. ncclenr.orlwebl�vctllablcert.l
How big of a pile triggers
monitoring?
The permittee must perform ana-
lytical monitoring if the facility
stores exposed accumulations of
sawdust, wood chips, bark, mulch,
or similar materials for longer than
seven (7) days. 'I`he permit does
not specify a size threshold because
a large area covered in "small
mounds" could impact stormwater
as much as one large pile. If rea-
sonable judgment tells you there
are piles on site, monitoring is re-
quired unless that material is re-
moved within a week. Also, rernov-
ing only the Lop portion of piles and
leaving significant amounts of the
material on the bottom does not.
satisfy the monitoring exemption.
I urthermore. in some cases
NCI)ENR may determine leachate
from such piles is a wastewater,
The facility should µreverit dis-
charge of pile leach,ite as inuch as
possible.
Do I have to keep a record of
every little piece of sawdust to
prove I don't have to monitor?
No. However, if the facility "opts
out" of analytical monitoring be-
cause it removes piles within a
week's time, D11'Q expects the facil-
ity to keep a record of when the ma.
terial was generated, and when and
how it was removed to demonstrate
short periods of storage.
If I'm sampling my discharge, do
I do qualitative monitoring at
the same time?
Yes.
Who can I call with questions?
Please contact Stormwater Permit-
ting Program staff at the office near-
est your location. 1-1elp is also avail-
able from the NCI)ENR's Division of
Environmental Assistance and Cus-
tomer Service at l-877-623-6748.

PART 1 INTRODUCTION
SECTION A: GENERAL PERMIT COVERAGE
All persons desiring to have facilities covered by this General Permit must register xvith the Division
of�Vater Quality (DbVQ) 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 21.1
,0100, staging 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 11crrnit. does not: cover activities or discharges covered by an individual N1'DE:S permit
until the individual permit has expired or has been revoked. Any person conducting an activity
covered by an indivicinal permit but which could be covered by this General 1'ermit may request:
ghat 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(1;), the facility may qualify for a No Exposure Exclusion from NPDES storrnwater
discharge permit requirements. Any owner or operator wishing to obtain a No Exposure Exclusion
must submit a No Exposure Certification Notice of Intent (NO1) form to the Division; must receive
approval by the Division; must maintain no exposure conditions unless authorized to discharge
under a valid NPD[:•:S 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 ("fMDL) 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 clemonstrating 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. Note that: the permit:tee must. identify impaired wagers (scheduled for "1'MM, development)
and waters already subject. to a "I'MD1, in the Site Overview, as outlined in the Stormwater Pollution
Prevention Plan, I)art:11, Section A. A list of approved "I'MDLs for the stage of"Nort:h Carolina can be

methods of operations and/or storage practices to eliminate or reduce exposure of
materials and processes t.o rainfall and run-on flows. Wherever practical, the permittce
shall prevent exposure of all storage areas, material handling operations, and manufaCtUring
or fueling operations. In areas where elimination of exposure is not practical, this review
shall document the feasibility of diverting the storrnwat:er run-on away from areas of
potential contamination.
(b) Secondary Containment Requirements and Records. Secondary containment is required
for: bulk storage of liquid materials including petroleum products; storage in any amount of
Section 3'13 of Tittle III of the Superfund Amendments and Reauthorization Act (SARA) water
priority chernicals; 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 rnechanisni. Any stormwater that

(BMI's) shall be provided. The installation and implementation of BMPs shall be based on
the assessment of the potential for sources to contribute significant quantities of'pollutants
to stormwater discharges and on data collected through monitoring of stormwater
discharges. The 13MP Summary shall include a written record of the specific rationale for
installation and implemcnt.ation of the selected site BMl's. The BMP Summary shall be
reviewed and updated annually.
Spill Prevention and Response Procedures. The Spill Prevention and Response Procedures
(SPRP) shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the Facility. Facility personnel responsible for implementing the SPRP shall be
identified in a written list incorporated into the SPRI' and signed and dated by each individual
acknowledging their responsibilities for the procedures. A responsible person shall be on -site
at all times during facility operations that have increased potential to contaminate stormwater
runoff through spills or exposure of materials associated with the facility operations. The SPRP
must he site stormwater specific. 'Therefore, an oil Spill Prevention Control and
Countermeasure plan (SPCC) may he a component of the SPRP, but may not be sufficient to
completely address the storrwater aspects of the SPRP. The common elements of the SPCC
tvith the SPRY may be incorporated by reference into the SPRP.

available to the Director or the Director's authorized representative immediately upon request:.
SECTION B: ANALYTICAL MONITORING REQUIREMENTS
A facility that retains exposed accumulations (either exposed to incident precipitation or exposed
to stormwater ram on) of sawdust, wood chips, hark, mulch, or other similarly sized material on site
for more than seven (7) days is required to monitor and report all the site stormwater discharges
for the parameters in Table 1.
The permittee may petition the DWQ Regional Office Surface 111/at.er Protection Supervisor to be excused from
the required monitoring:
a) upon a DWQ Compliance Evaluation Inspection, and;
b) on the basis that DWQ concludes that taken as a whole, site -wide conditions support the
assessment of very limited risk of stormwater pollution from the site.
c) Among any other factors deemed relevant in his or her own considerations, the Regional Office
Supervisor shall consider whether the amount of accumulated exposed materials may be deemed
de minimis with respect to the potential to generate stormwaler runoff pollutants. Given that all site
conditions may be relevant to the determination of what constitutes a de rninimis amount, such
determinations shall he made on a 'case -by -case basis', and shall not: be assumed to he generally, or
specifically, transferrable to any other permitted site, regardless of superficial similarities.
(1) The Regional Office Supervisor will communicate any such determination in writing, and shall state
any qualifying conditions for the permittee's continuing release from monitoring. DWQ's release
letter may remain in effect through subsequent reissued versions of this permit, unless the release
letter provides for other conditions or duration.
e) If released from monitoring, the permittee must still continue to submit semi-annual Discharge
Monitoring; Reports, with the notation: "Released from Monitoring by DWQ Regional Office."
If at any tame there are changes to DWQ's initial site assessment, or to the initial site operating;
circumstances, the permittee must immediately begin analytical monitoring and reporting in accordance
with Tables 1 and 2, and must immediately inform the DWQ Regional Office that analytical monitoring; has
been instituted.

during a measureable storm event, until either another permit is issued for this facility or until this permit is
revoked or rescinded. See 'Table 2 for schedule of monitoring periods through the end of this permitting cycle. If
the facility is monitoring monthly because of "Pier Two or'I'hrce response actions under the previous General
Permit, the facility should contimie a monthly monitoring and reporting schedule.
2 Grab samples shall be collected within the first 30 minutes of discharge.
3 Sample Location: Samples shall be collected at each siorm,,vater discharge out:fall (SDO) unless representative
outfall status (ROS) has been granted. A copy of the DWQ letter granting ROS shall be kept. on site.
9 For each sampled measureable storm event, the total precipitation must be recorded. An on -site rain gauge
reading must be recorded. Where isolated sites are unmanned for extended periods of tirne, a local rain gauge
reading may be substituted for an on -site reading.
All analytical monitoring shall be performed during a measureable storm event at each
storm+eater discharge out:fall (SDO).
A measurable storm event is a storm event that results in an actual discharge from the permit.t.ed
site out:fall. The previous measurable storm event must have been at least 72 hours prior. ']'he 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.
A minimum of 60 days must separate Period 1 and Period 2 sample dates unless monthly
monitoring has been instituted under other requirements of this permit.
The permittee shall complete the analytical samplings in accordance with the schedule specified in
'I'ahle 2, unless adverse weather conditions prevent sample collection (see Adverse Weather in
Definitions). Inability to sample because of adverse weather conditions must be documented in the
SPIT and recorded on the DMR. Sampling is not required outside of the facility's normal operating;
hours.
Failure to monitor and report semi-annually per permit terms may result in the Division requiring
monthly monitoring anti reporting 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.

Poot:notes:
1 Maintain semi-annual monitoring and reporting during permit renewal process unless other
provisions of this permit prompt monthly sampling.
2 If no discharge occurs during the sampling period, the permittee must submit. a monitoring report
indicating "Ne Flow" or "No Discharge" tvithin 30 days of the end of the sampling period.
The permittee must report the results from each sample taken within the monitoring period (See Part
III E). However, for purposes of benchmark comparison and Tiered response actions, the permittee
shall use the analytical results from the first sample with valid results within the monitoring period.
The permittee shall compare monitoring results to the berchmark values in 'fable 3. The benchmark
values in Table 3 are not permit limits, but should be used as guidelines for implementation of the
permit.tee's SPPP. Exceedances of benchmark values require the permittee to increase monitoring and
reporting, increase management actions, increase record keeping, and/or install stormwater Best
Management Practices (HMPs) in a tiered program. See descriptions of "Tier One, Tier Two, and Tier
Three response actions below. In the event that the Division releases the permittee from continued
monthly monitoring and reporting under Tier Two or Tier Three, DWQ's release letter may remain in
effect through subsequent reissuance of this permit, unless the release letter provides for other

5. Record each instance of a Tier One response in the SPPP. 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.
6. Note: Benchmark exceedances fora different parameter separately trigger the several tiered response
requirements.
Tier Two
If: The first valid sampling results from two consecutive monitoring periods are above the benchmark values
for any specific parameter at a specific discharge outfall;
Then: The permittee shall:
1. Repeat all title required actions outlined above in Tier One.
2. Immediately institute monthly monitoring and reporting for all parameters at: every outfall where a
sampling result exceeded the benchmark value for two consecutive samples. Monthly (analytical and
qualitative) monitoring and report.ing shall continue until three consecutive sample results are below
the benchrnark values.
3. If no discharge occurs during the sampling period, t:he permittee is required to submit a monthly
monitoring report indicating "No Flow" to comply with reporting requirements.
h. Alternatively, in lieu of steps 2 and 3, the permittee may, after two consecutive exceedances, exercise
the option of contacting the DWQ Regional Office Supervisor as provided below in Tier Three. The
Regional Office Supervisor may direct the response actions on the part of the permittee as provided in
Tier Three, including reduced or additional sampling parameters or frequency.
5. Maintain a record of the Tier Two response in the SPPP.
Continue Tier Two response obligations throughout the permit COC renewal process.

SECTION C: QUALITATIVE MONITORING REQUIREMENTS
All facilities covered by this permit must perform Qualitative Monitoring. The purpose of
qualitative monitoring is to evaluate the effectiveness of the SPPP and to assess new sources of
st:ormwatcr pollution. Qualitative monitoring of stormwater outfalls must he performed during; a
measurable storm event.
Qualitative monitoring requires a visual inspection of each stormwater outfall associated with
industrial activity re ardless of representative outfall status. Qualitative monitoring shall be
perforriied semi-annually as specified in Table 4, and during required analytical monitoring events if
applicable (unless the permittee is required to perform further qualitative sampling per the
Qualitative Monitoring Response below). Inability to sample because of adverse weather
conditions must: be documented in the SPIT and recorded on the DMR (see Adverse' feather in
Definitions). Only SI)Os discharging, stormwater associated with industrial activity must be
monitored (See f)cfinitions).
In the event an atypic li condition is noted at a stormwater discharge outfall, the permittee shall
document the suspected cause of the condition and anv actions taken in response to the discovery.

Qualitative Monitoring Response, below. A written record of the permittee's investigation, evaluation,
and response actions shall be kept in the S11111.
Qualitative Monitoring Response
Qualitative monitoring is for the purposes of evaluating SPPP effectiveness, assessing new sources of
storm ater pollution, and prompting the permittee's response to pollution. If the permittee
repeatedly fails to respond effectively to correct; problems identified by qualitative monitoring, or if
the discharge causes or contributes to a water quality standard violation, DWQ may but is not
limited to:
• require that the permittee revise, increase, or decrease monitoring frequency for some or
all parameters (analytical or qualitative);
• require the permittee to install structural stornivvater controls;
• require the permittee to implement other stormwater control measures;
• require the permit:t:ee to perform upstream and downstream monitoring to characterize
impacts on receiving waters; or
• require the permittee implement site modifications to qualify for a No Exposure Exclusion.
SECTION D: ON -SITE VEHICLE MAINTENANCE MONITORING REQUIREMENTS
Facilities that have any vehicle maintenance activity occurring on -site which uses more than 55
gallons of new motor oil and hydraulic oil per month, combined, when averaged over the
calendar year shall perform analytical monitoring as specified below in'rahle 5. All analytical
monitoring shall be performed during; a measureable storm event at: all stormwater discharge

Permit No, NCG210000
Sample location: Samples shall be collected at each stormwater discharge outfall (SD0) that discharges
stormwater runoff from area(s) where vehicle maintenancc activities occur, unless representative outfall
status (ROS) has been granted. A copy of the later granting ROS shall be kept on site.
For each sampled measureahle storm event, the total precipitation must be recorded. An on -site rain
gauge reading must be recorded. Where isolated sites are unmanned for extended periods of time, a local
rain gauge reading may be substituted for an on -site reading.
The permittee shall complete the analytical samplings in accordance with the schedule specified in
Table 2, unless adverse weather conditions prevent sample collection (see Adverse Weather in
Definitions). Inability to sample because of adverse weather conditions must. he documented in the
SPPP and recorded on the DMR. Sampling is not required outside of the facility's normal operating
hours.
Failure to monitor amd. report semi-annually per pertnit- terms may result in the Division requiring
monthly monitoring for all parameters for a specific(.] 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.
The permittee shall compare monitoring results to the benchmark values in Table 6. Exceedances of
benchmark values require the permittee to increase monitoring, increase management actions, increase
record keeping, and/or install stormwatcr Best Management Practices (13MPs) in a tiered program. See
descriptions of Tier One, Tier Two, and Tier Three response actions in fart Il Section R above. In the
event that the Division releases the permittee from continued monthly monitoring under Tier T wo or
"Pier Three, DWQ's release letter may remain in effect through subsequent reissuance of this permit,
unless the release letter provides for other conditions or duration.
The permittee must. report the results from each sample taken within the monitoring period (See Part
III E). However, for purposes of benchmark comparison and Tiered response actions, the permittee
shall use the analytical. results from the first sample with valid results within the monitoring period.
