Inspection Summary
The SWPPP has been ignored presumably since 2010. A reinvestment of time and resources must occur to get the site
on track to compliance. Upon entry to the site, a large head boat was being sanded without containment. Under the boat
lift, the gravel was stained green The last monitoring was in 2010, which the benchmarks were exceeded significantly.
Discussed the permit conditions aid requirements with the dockmaster, Mike. He showed an urgency to rectify the
deficiencies that made me confident that the goals of the marina are and will be consistant with the state's expectations.
Please contact this office after the first sampling event and email me the results. Reinspection in one year

Dear Permittee:
In response to your renewal application for continued coverage under stormwater General Permit NCG190000 the Division of
Water Quality (DWQ) is forwarding herewith the reissued stormwater General Permit. This permit is reissued pursuant to the
requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between the state of North
Carolina and the U.S. Environmental Protection Agency, dated October 15, 2007 (or as subsequently amended.)
The following information is included with your permit package:
• A new Certificate of Coverage :
• A copy of stormwater General Permit NCG190000
• A copy of a Technical Bulletin for the General Permit
• Five copies of the Discharge Monitoring Report (DMR) Form
• Five copies of the Qualitative Monitoring Report Form,
The General Permit authorizes discharges of stormwater only, and it specifies your obligations with respect to stormwater
discharge controls, management, monitoring, and record keeping. Please review the new permit to familiarize yourself with all the
changes in the reissued permit.
The more significant changes in the General Permit since your last Certificate of Coverage include the following:
• Permit cover page — Coverage is expanded to include industrial activities similar to the categorically identified industries.
• Part I Section A — This part explains that the No Exposure Exclusion from permitting option may be available to the permittee.
• Part 11 Section A — Several minor expansions and clarifications of the required content of the Stormwater Pollution Prevention
Plan have been added. Also, there is an added requirement for a Solvent Management Plan. Please be sure that your plan is
updated to comply with the new requirements.
• Part Il Section B - Revised provisions require that stormwater discharges be sampled twice per year, and that the sampling
results be compared to new numerical benchmark values. (The previous cutoff concentrations have been eliminated.)
• Part 11 Section B — Monitoring for some metals has been added to the analytical monitoring requirements.
• Part 11 Section B — Beginning with monitoring in Year 3-Period 1, revised provisions require the permittee'to execute Tier One
and Tier Two response actions, based on the first benchmark exceedence (Tier One) and the second consecutive benchmark
exceedence (Tier Two). Tier Two requires that the permittee institute monthly monitoring instead of twice -per -year monitoring,
until three consecutive monitoring events show no benchmark exceedences.
• Part II Section B — Beginning with monitoring in Year 3-Period 1, this part contains a new provision that four exceedences of
any particular benchmark will trigger increased.DWQ involvement in the permittee's stormwater management and control
actions. DWQ may direct the permittee to apply for an individual permit, or may direct the implementation or installation of
specific stormwater control measures.
• Part II Section C — Qualitative monitoring must now be conducted during a representative storm event.

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 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 discharge of stormwater associated with industrial activity that
,.has a point source discharge to the surface waters of the state.
Any.owner or operator not wishing to be covered or limited by this Genera] 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 of 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 from permitting
exist submit a No Exposure Certification 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 reapply for the No Exposure Exclusion once every five (5) years.
Any- facility may apply for new or continued coverage under this permit until a Total Maximum Daily
Load (TMDL) for pollutants for stormwater discharges is established: A TMDL sets a pollutant loading
limit that affects a watershed, or portion of a watershed, draining.to an impaired water, For stormwater'
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 the Division 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, and once that permit is
effective, will no longer have coverage under this general permit. [Note the facility must identify
impaired waters (scheduled for TMDL development) and waters already subject to a TMDL in the Site
Plan, as outlined in the Stormwater Pollution Prevention Plan (SPPP), Part 11, Section A. L]
During the period beginning on the effective date of the permit and lasting until expiration, the Permittee
is authorized to discharge stormwater associated with the industrial activity. Such discharges shall he
controlled, limited, and monitored as specified in this permit.
SECTION S: PERMITTED ACTIVITIES
Until this permit expires or is modified or revoked, the permittee is authorized to discharge stormwater to
the surface waters of North Carolina or separate storm sewer system which has been adequately treated
and managed in accordance with the terms and conditions of this General Permit. All discharges shall be
in accordance with the conditions of this 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 stormwater
Part I and II Page 1 of 9

Permit No. NCG190000
discharges allowed by this General Permit shall not cause or contribute to violations of Water Quality
Standards.
This General Permit does not allow discharges determined by the Division of Water Quality to be
wastewaters. The discharge and/or disposal of vehicle wash water or vehicle rinse water is not permitted
by this General Permit. Wash water and rinse water must be directed to a sanitary sewer system or
permitted by a separate wastewater permit issued by the Division. The discharge and/or disposal of any
paints, solvents, petroleum, diesel oil or oil/water compounds applied to any surface of the vehicles is not
permitted by this General Permit.
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: STORMWATER POLLUTION PREVENTION PLAN
The Permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as the Plan.
This Plan shall be considered public information in accordance with Part III, Standard Conditions,
Section E, Paragraph 3 of this General Permit. The Plan shall include, at a minimum, the following
items:
1. Site Plan. The site plan shall provide a description of the physical facility and the potential.-_
pollutant sources which may be expected to contribute to contamination of stormwater
discharges. The site plan shall contain the following:
(a) A general location map (USGS quadrangle map or appropriately drafted equivalent
map), showing the facility's location in relation to transportation routes and surface
waters, the name of the receiving water(s) to which the stormwater outfall(s) discharges,
or if the discharge is to a municipal separate storm sewer system, the name of the
municipality and the ultimate receiving waters, and accurate latitude and longitude of
the point(s) of discharge. The general location map (or alternatively the site map) shall
identify whether each receiving water is impaired (on the state's 303(d) list of impaired
waters) or is located in a watershed for which a TMDL has been established, and
what the parnmeter(s) of concern are.
(b) A narrative description of storage practices, loading and unloading activities, outdoor
process areas, dust or particulate generating or control processes, and waste disposal
practices. A narrative description of the potential pollutants which could be expected to
be present in the stormwater discharge from each outfall.
(c) A site map drawn at a scale sufficient to clearly depict: the site property boundary, the
stormwater discharge outfalls, all on -site and adjacent surface waters and wetlands,
industrial activity areas (including storage of materials, disposal areas, process areas,
loading and unloading areas, and haul roads), site topography, all drainage features and
structures, drainage areas for each outfall, direction of flow in each drainage area,
industrial activities occurring in each drainage area, buildings, existing BMPs, and
impervious surfaces. The site map shall include a distance legend and must indicate the
percentage of each drainage area that is impervious. In addition, the following industrial
Part I and H Page 2 of 9

Permit No. NCG 190000
activity areas must also be identified on the site map: fueling, engine maintenance and
repair; vessel maintenance and repair, washing, painting, sanding, blasting, welding, and
metal fabrication.
(d) A list of "significant spills or leaks of pollutants that have occurred at the facility during
the three (3) previous years and any corrective actions taken to mitigate spill impacts.
(e) Certification that the stormwater outfalls have been evaluated for the presence of non-
stormw�rter discharges. The certification statement will be signed in accordance with the
requirerrients found in Part III, Standard Conditions, Section B, Paragraph 5. The
permittee shall re -certify annually that the stormwater outfalls have been evaluated for
the presence of non-stormwater discharges.
Stormwater Management Plan, The stormwater management plan shall contain a narrative
description of the materials management practices employed which control or minimize the
exposure of significant materials to stormwater, including structural and nonstructural measures.
The stormwater management plan, at a minimum, shall incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing the
methods of operations and/or storage practices to eliminate or reduce exposure of
materials and processes to stormwater. Wherever practical, the permittee shall prevent
exposure of all storage areas, material handling operations, and manufacturing or fueling
operations. In areas where elimination of exposure is not practical, the stormwater
management plan shall document the feasibility 'of diverting stormwater runoff away
from areas of potential contamination.
(b) Secondary Containment Requirements and Records. Secondary containment is required
for: bulk storage of liquid materials; storage in any amount of Section 313 of Title III of
the Superfraiid 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), and 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 years.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMP) 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 data collected through monitoring
of stormwater discharges. The BMP Summary shall include a written record of the
specific rationale for installation and implementation of the selected site BMPs. The
BMP Summary shall be reviewed and updated annually.
3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP) shall
incorporate an assessment of potential pollutant sources based on a materials inventory of the
facility. Facility personnel (or the team) responsible for implementing the SPRP shall be
identified in a written list incorporated into the SPRP and signed and dated by each individual
Part I and 11 Page 3 of 9

Permit No. NCG 190000
acknowledging their responsibilities for the plan. A responsible person shall be on -site at all
times during facility operations that have the potential to contaminate stormwater runoff through
spills or exposure of materials associated with the facility operations. The SPRP must be site
stormwater specific. Therefore, an oil Spill Prevention Control and Countermeasure plan
(SPCC) may be a component of the SPRP, but may not be sufficient to completely address the
stormwater aspects of the SPRP. The common elements of the SPCC with the SPRP may be
incorporated by reference into the SPRP.
4. Solvent Management Plan. The Solvent Management Plan shall be incorporated as a separate -
chapter into the Stormwater Pollution Prevention Plan (SPPP). The Solvent Management Plan Ahall
include an annually updated and quantified inventory of the solvents present on site during the
previous three years; a narrative description of the in -plant locations and uses of the solvents, the
method of disposal including quantities disposed on -site and off -site; and the management
procedures and engineering measures for assuring that solvents do not spill or leak into stormwater.
If solvents are not stored or used onsite, then the owner must certify that in the SPPP. DWQ may at
its discretion require submittal, review, and approval of the Solvent Management Plan. The
discharger shall include the following signed certification statement on each discharge monitoring
report: "Based upon my inquiry of the person or persons directly responsible for managing
compliance with the permit requirement for managing solvents, I certify that to the best of my
knowledge and belief, no leak, spill, or dumping of concentrated solvents into the stormwater or onto
areas which are exposed to rainfall or stormwater runoff has occurred since filing the last discharge
monitoring report. 1 further certify that this facility is implementing all the provisions of the Solvent
Management Plan included in the Stormwater Pollution Prevention Plan."
5. Preventative Maintenance and Good Housekeeping Program. A preventative maintenance and
good housekeeping program shall be developed. The program shall list all stormwater control
systems, stormwater discharge outfalls, all on -site and adjacent surface waters and wetlands,
industrial activity areas (including material storage areas, material handling areas, disposal ireas,
process areas, loading and unloading areas, and haul roads), all drainage features and structures,
and existing.structural BMPs. The program shall establish schedules of inspections,
maintenance, and housekeeping activities of stormwater control systems, as well as facility
equipment, facility areas, and facility systems that present a potential for stormwater exposure or
stormwater pollution. Inspection of material handling areas and regular cleaning schedules of
these areas shall be incorporated into the program. Timely compliance with the established
schedules for inspections, maintenance, and housekeeping shall be recorded in writing and
maintained in the SPPP.
Employee Training. Training programs shall be developed and training provided at a minimum
on an annual basis for facility personnel with responsibilities for: spill response and cleanup,
preventative maintenance activities, and for any of the facility's operations that have the potential
to contaminate stormwater runoff. Facility personnel (or team) responsible for implementing the
training shall be identified, and their annual training shall be documented by the signature of
each employee trained. Additional required training items include: used oil management, spent
solvent management, disposal of spent abrasives, disposal of vessel wastewaters, fueling
procedures, sanding, painting and blasting procedures, and used battery management.
Responsible Party, The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and revision
to the Plan. Responsibilities for all components of the Plan shall be documented and position
assignments provided.
Part I and R Page 4 of 9

Permit No. NCG 190000
Plan Amendment. The permittee shall amend the Plan whenever there is a change in design,
construction, operation, or maintenance which has a significant effect on the potential for the
discharge of pollutants to surface waters. All aspects of the Stormwater Pollution Prevention
Plan shall be reviewed and updated on an annual basis. The annual update shall include an
updated list of significant spills or leaks of pollutants for the previous three years, or the notation
that no spills have occurred. The annual update shall include written re -certification that the
stormwater outfalls have been evaluated for the presence of non-stormwater discharges. Each
annual update shall include a documented re-evaluation of the effectiveness of the BMPs listed
in the BMP Summary of the Stormwater Management Plan.
The Director may notify the permittee when the Plan does not meet one or more of the minimum
requirements of the permit. Within 30 days of such notice, the permittee shall submit a time
schedule to the Director for modifying the Plan to meet minimum requirements. The permittee
shall provide certification in writing (in accordance with Part III, Standard Conditions, Section B,
Paragraph 5) to the Director that the changes have been made.
9. Facility Inspections. Inspections of the facility and all stormwater systems shall occur as part of
the Preventative'Maintenance and Good Housekeeping Program at a minimum on a semi-annual
schedule, once during the first half of the year (January to June), and once during the second half
of the year (July to December), with at least 60 days separating inspection dates (unless
performed more frequently than semi-annually). These facility inspections are different from,
and in addition to, the stormwater discharge characteristic monitoring required in Part R of this

discharge outfall (SDO) regardless of representative outfall status.
If the permittee's qualitative monitoring indicates either thai existing stormwater BMPs. are ineffective, or that
significant stormwater contamination is present, the permittee. shall investigate potential causes, evaluate the
feasibility of corrective"actions, and implement those corrective actions appropriate. A written record of the
permittee's investigation, evaluation, and response actions shall be kept in the Stormwater Pollution
Prevention Plan.
Qualitative monitoring is for the purposes of evaluating the effectiveness of the Stormwater Pollution
Prevention Plan (SPPP), assessing new sources of stormwater pollution, and prompting the permittee's
response actions 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:
• require that the permittee revise, increase, or decrease the monitoring frequency for the remainder
of the permit;
• rescind coverace 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; or
• require that the permittee implement site modifications to qualify for the No Exposure Exclusion.
Qualitative monitoring will be performed twice per year, in accordance with the schedule in
Table 2. A minimum of 60 days must separate Period I and Period 2 monitoring dates, unless
monthly sampling has been instituted under a Tier Two response as part of other analytical monitoring
requirements in this permit.

a Y Stormwater Permit NCG190000'- w
Technical Bulletin for NCG190000, Volume II : Last Revised 8/20/2009
What activities are covered by this general permit?
NCG190000 allows stormw iter discharges associated with activities classified as establishments primarily en-
gaged in: operating Marinas [standard industrial classification (SIC) 44931 that provide vehicle maintenance activities, and
Ship and Boat Building and Repairing [SIC 3731; and like activities deemed by DWQ to be similar in the process and/or the
exposure of raw materials, products, by-products, or waste materials.
+ This General Permit does not authorize discharges at the facility containing waste streams including, but not limited to, bilge
and ballast cater, cooling water, sam.fan, +castes, power and hand +cashing, f Ia.srirng,.scauling, and fish clearing stations. A
separate wastewater- permit nrrry be required for these and other similar ivaslei'vater discharges.
What are the key permit requirements?
• Implement a Stormwater Pollution Prevention Plan (SPPP) (Part II, Section A).
• Provide secondary containment for all bulk storage of liquid-, materials (Part II, Section A, 2.(b)).
• Perform, document, and report analytical and qualitative monitoring during a representative storm event
(Part Ii, Section B & Q.
What has changed since the last renewal?
• Twice per year analytical monitoring of pH, Oil & Grease, Total'Suspended Solids (TSS), Copper, Aluminum,
Lead, Zinc, and Iron.
• Refinements and clarifications.to the SPPP requirements; refer to Part lI, Section A.
• Tiered response requirements for benchmark exceedences based on analytical results beginning with the
-monitoring-iii Year 3 — Period l (Sample 5), and direction to notify the Regional Office in the event of four
benchmark exceedences. Berichmarks are not limits.
• Twice per year qualitative monitoring. during a representative storm event.
• Requirement to use forms provided by the Division to record qualitative monitoring results.
• Requirement to submit an annual monitoring summary to the DWQ Regional Office (RO).
• Develop a Solvent Management Plan (Part I1, Section A).
What are BMPs, and why are they important?
The SPPP should include Best Management'Practices (BAIPs) to control discharge of pollutants from a facil-
ity's stormwater outfalls. BMPs include a variety of things that help minimize potential for pollutants to get
into the stormwater draining from a facility. There are different types of BMPs:
Non-structural (practices or activities) BMPs include:
* Eliminating exposure of materials and -equipment wherever possible by moving them to indoor locations.
* Practicing good housekeeping on -site. Handle and store materials at 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. Cleanup spills immediately.
* Establishing bulk storage tank protocols that minimize the risk of spills daring loading and unloading.
* Maintaining wash pads and keeping them clean of paint chips, debris, and particles.
Structural (equipment, or devices) BMPs include:
* Containment dikes around the loading areas of bulk liquid storage containers.
* Roofs and secondary containment around materials so that they aren't exposed to stormwater.
* Collection systems around boat wash areas to direct wash water to a holding tank or sanitary sewer.
* Converting from a liquid operation to a dry operation foi- hull maintenance and cleaning.
* Collection of debris from paint chips around boat maintenance areas to minimize contaminated stormwater.
* Hull maintenance areas designed to be done on dry land as far away from the water as possible.

Frequently Asked Questions
Could I be exempt from a
NPDES stormwater permit?.
Possibly. A facility with industrial
activities subject to the NPDES
Stormwater regulations that elimi-
nates all potential stormwater ex-
posure may be eligible for a No
Exposure Exclusion from a permit.
A facility that rneets this condition
may submit a No Exposure Certifi-
cation application (see our website:
http://h2o.enr.5tate.nc.uslsu) for a
No Exposure Exclusion. The facil-
itv must. re -certify No Exposure
every five (5) rears.
What if I sell my business, or
the name changes?
This change is a minor modification
and requires the Director's approval
before the Permittee can be absolved
of his responsibility under the permit.
Complete the Name/Ownership
Change Form SWU-239, available on
our website:,
http://l12o.etir.staw. ne,uelsu
Do I have to monitor all the
outfalls? `
Yes. However, you may request
Representative Outfall Status
(ROS). If approved, this status
allows analytical monitoring at
fewer outfalls. To request ROS,
submit a ROS'Request Form SWU-
ROS to the DWQ Regional Office.
The form is available on our web -
site:
litt.p:l/h2o.em•.st,rte.nc.us/su
Other resources
In addition to the Stormwater Per-
mitting Unit's website above, the
Division of Pollution Prevention
and Environmental Assistance is a
valuable resource. The DPPEA
has specific information about how
to minimize pollutants at
various industries. Call
[phone] or visit:
http://www.p2pays.orp;/
Does a certified lab need to
analyze my samples?
Monitoring under all NPDES per-
mits must be conducted in accor-
dance with test procedures ap-
proved under federal regulations in
40 CFR §136- All labs certified by
North Carolina perform analysis in
accordance with those procedures.
N.C. certification requirements do
not apply to stormwater only dis-
charges, but data gathered under a
NPDES 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 from: hap 11
h2o.enr.state. nc. us/l.ablcert.htm.
Note that pH is a field parameter
and must be measured within
15 minutes. You must train on -
site staff to .measure pH using ap-
proved methods or contract with
commercial services. All entities
with -field parameter certification
per 15A NCAC hH .0800 can ana-
lyze pH in accordance with federal
procedures (see website for list).
Can my boat wash water be
discharged to or with my
stormwater?
No. Boat wash water, whether
from hand washing or power wash-
ing, is considered a wastewater.
No wastewater discharges are att-
thorized to be discharged by this
stormwater permit. Wastewater is
not allowed to mix, or be `diluted",
with stormwater and discharged
at a stormwater outlet unless per-
mitted by a separate wastewater
permit. Stormwater commingled
with wastewater is all considered
a wastewater, and must be han-
dled as such. A separate waste-
water permit is required in or-
der to discharge wastewaters
to surface waters. Some possi-
ble alternatives (which may re-
quire a separate additional permit)
for minimizing wastewater dis-
charge to surface waters include:
discharge to a municipal wastewa-
ter treatment plant, recycling, cony
version _of activities to dry proc-
esses which allow for easy clean-
up and maintenance, and proper
disposal of the wastes generated
from industrial activities. The
NCG190000 permit is applicable to
a marina who is offering a vehicle
maintenance service, which in-
cludes boat cleaning. It is not ap-
plicable for an individual washing
their own boat at a marina. How-
ever, it is highly encouraged that
the facility educate, and monitor
the use of appropriate 13MPs by
the'boat owners when washing
their boats to minimize impacts to
surface water as much as possible.

.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
from permitting must submit a No Exposure Certification NO] form to the Division; must receive
approval by the Division; must maintain no exposure conditions unless authorized to discharge
under a valid NPI)ES 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 discharges is established. A TMD1, sets a
pollutant -loading limit that affects a watershed, or portion of a watershed, draining to an impaired
water. For stormwater 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
the Division 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 permittee must identify impaired waters
(scheduled for TMDL development) and waters already subject to a 'TMDL in the Site Overview, as
outlined in the Stormwater Pollution Prevention Plan (SPPP), Part 11, Section A.1. A list of approved
TMDLs for the state of North Carolina can be found at

PART II MONITORING, CONTROLS, AND LIMITATIONS FOR PERMITTED
DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The permittee shall develop and implement a Stormwater Pollution Prevention Plan (SPPP). The
SPPP shall be maintained on site unless exempted from this requirement by the Division. The SPPP
is public information in accordance with Part III, Section L, paragraph 3 of this permit. The SPPP
shall include, at a minimum, the following items:
1. Site Overview. The Site Overview shall provide a description of the physical facility and the
potential pollutant sources that may he expected to contribute to contamination of stormwater
discharges. The Site Overview shall contain the following:
(a) A general location map (USGS quadrangle map or appropriately drafted equivalent map),
showing the facility's location in relation to transportation routes and surface waters; the
name of the receiving waters to which the stormwater outfalls discharge, or if the discharge
is to a municipal separate storm sewer system, the name of the municipality and the
ultimate receiving waters; and latitude and longitude of the points of stormwater discharge
associated with industrial activity. The general location -map (or alternatively the site map)
shall identify whether any receiving waters are impaired (on the state's 303(d) list of
impaired waters) or if the site is located in a watershed for which a TMDL has been
established, and what the parameters of concern are.
(b) A narrative description of storage practices, loading and unloading activities, outdoor
process areas, dust or particulate generating or control processes, and waste disposal
practices. A narrative description of the potential pollutants that could be expected to be
present in the stormwater discharge from each outfall.
(c) A site map drawn at a scale sufficient to clearly depict: the site property boundary; the
stormwater discharge outfalls; all on -site and adjacent surface waters and wetlands, -
industrial activity areas (including storage of materials, disposal areas, process areas,
loading and unloading areas, and haul roads); site topography; all drainage features and
structures; drainage area boundaries and total contributing area for each out:fall; direction
of Clow in each drainage area; industrial activities occurring in each drainage area;
buildings; stormwater Best Management Practices (13MPs); and impervious surfaces. The
site map must indicate the percentage of each drainage area that is impervious, and the site
map must include a graphic scale indication and north arrow. In addition, the following
industrial activity areas must: also be identified on the site map: fueling, engine maintenance
and repair, vessel maintenance and repair, washing, painting, sanding, blasting, welding,
and metal fabrication.
(d) A list of significant spills or leaks of pollutants during the previous three (3) years and
any corrective actions taken to mitigate spill impacts.
(e) Certification that the stormwater outfalls have been evaluated for the presence of non-
stormwater discharges. The permittee shall re -certify annually that the stormwater
outfalls have been evaluated for the presence of non-stormwater discharges. If non-
stormivater discharges are present, the permittee shall identify the source and record whether
Part 11 Page 1 of 10

Permit No. NCG190000
the discharge is otherivise permitted (by rule or a different permit). The permittee shall
evaluate the environmental significance of the non-stormwater discharges and include a
summary written record with the certification. The certification statement and summary
written record shall be retained with the SPPP, and shall be dated and signed in accordance
with the requirements found in Part III, Section 13, paragraph 5.
1. Stormwater Management Strategy. The Stormwater Management Strategy shall contain a
narrative description of the materials management practices employed which control or
minimize the stormwater exposure of significant materials, including structural and
nonstructural measures. The St:orm%vater Management Strategy, at a minimum, shall
incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing the
methods of operations and/or storage practices to eliminate or reduce exposure of
materials and processes to rainfall and runoff flows. Wherever practical, the permittee 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 stormwater runoff away from areas of potential
contamination.
(b) Secondary Containment Requirements and Records. Secondary containment is
required for: hulk storage of liquid materials including petroleum products; storage in any
amount of Section 31.3 of Title HI of the Superfund Amendments and Reauthorization Act
(SARA) water priorit.v 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 he 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.
Anv 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 (S) years. For the purposes of effective stormwater
pollution prevention the SPPP is intended to be broader and more comprehensive than a
federal oil Spill Prevention, Control, and Countermeasure Plan (SPCC). For facilities subject
to a federal SPCC plan, any portion of the federal SPCC plan fully compliant with the
requirements of this permit may be used to demonstrate compliance with this permit.
(c) BMP Summary. A listing of site structural and non-structural Best Management Practices
(13MPs) 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 BMP Summary shall include a written record of the specific rationale for
installation and implementation of the selected site BMPs. The BMP Summary shall be
reviewed and updated annually.
3. 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 SPRP and signed and dated by each individual
Part 11 Page 2 of 10

Permit No. NCG 190000
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 be 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 stormwater aspects of the SPRP. The common elements of the SPCC
%with the SPRP may be incorporated by reference into the SPRP.
q. Solvent Management Plan, The Solvent Management Plan shall be incorporated as a separate
chapter into the Stormwater Pollution Prevention Plan (SPPP). The Solvent Management: Plan shall
include an annually updated and quantified inventory of the solvents present on site during the
previous three years; a narrative description of the facility locations and uses of the solvents, the
method of disposal including quantities disposed on -site and off -site; and the management
procedures and engineering measures for assuring that solvents do not spill or leak into
stormwater. If solvents are not stored or used onsite, then the owner must certify that in the SPPP.
DEMI,R may at its discretion require submittal, review, and approval of the Solvent Management
Plan. The discharger shall include the following signed certification statement on each discharge
monitoring report: "Based upon my inquiry of the person or persons directly responsible for
managing compliance with the permit requirement for managing solvents, I certify that to the best
of my knowledge and belief, no leak, spill, or dumping of concentrated solvents into the stormwater
or onto areas which are exposed to rainfall or stormwater runoff has occurred since filing the last
discharge monitoring report. I further certify that this facility is implementing all the provisions of
the Solvent Management Plan included in the Stormwater Pollution Prevention Plan."
Preventative Maintenance and Good Housekeeping Program. A preventative maintenance
and good housekeeping program shall be developed and implemented. The program shall
address all stormwater control systems (if applicable), stormwater discharge outfalls, ali on -site
and adjacent surface waters and wetlands, industrial activity areas (including material storage
areas, material handling areas, disposal areas, process areas, loading and unloading areas, and
haul roads), all drainage features and structures, and existing structural BMPs. The program
shall establish schedules of inspections, maintenance, and housekeeping activities of
stormwater control systems, as well as facility equipment, facility areas, and facility systems
that present a potential for stormwater exposure or stormwater pollution where not already
addressed under another element of the SPPP. Inspection of material handling areas and
regular cleaning schedules of these areas shall be incorporated into the program. Timely
compliance with the established schedules for inspections, maintenance, and housekeeping
shall be recorded and maintained in the SPPP.
6, Facility Inspections. Inspections of the facility and all stormwater systems shall occur as part
of the Preventative Maintenance and Good housekeeping Program at a minimum on a semi-
annual schedule, once during the first half of the year (January to June), and once during the
second half (July to December), with at least 60 days separating inspection dates (unless
performed more frequently than semi-annually). These facility inspections are different from,
and in addition to, the stormwater discharge characteristic monitoring at the outjalls required
in Part 11 6, C, and D of this permit.
7. Employee Training. Training programs shall he developed and training provided at a
minimum on an annual basis for facility personnel with responsibilities for: spill response and
cleanup, preventative maintenance activities, and for any of the facility's operations that have
the potential to contaminate stormwater runoff. The annual training shall be documented by
the signature and printed or typed name of each employee trained. Additional required
training items include: used oil management, spent solvent management, disposal of spent
Part 11 Page 3 of 10

Permit No. NCG190000
abrasives, disposal of vessel wastewaters, fueling procedures, sanding, painting and blasting
procedures, and used battery management.
B. Responsible Party. The SPPP shall identify a specific position or positions responsible for the
overall coordination, development, implementation, and revision of the SPPP. Responsibilities
for all components of the SPPP shall he documented and position assignments provided,
9. SPPP Amendment and Annual Update. All aspects of the SPPP shall be reviewed on an
annual basis. The permittee shall amend the SPPP whenever there is a change in design,
construction, operation, site drainage, maintenance, or configuration of the physical features
which may have a significant effect on the potential for the discharge of pollutants to surface
waters. The annual update shall include at a minimum:
(a) an updated list ofsignificant spills or leaks of pollutants for the previous three (3)
years, or the notation that no spills have occurred (element of the Site Overview);
(b] a ivritten re -certification that the stormivoter outfalls have been evaluated for the
presence of nun-stormmvuter discharges (element of the Site Overview),
(c) a documented re-evaluation of the effectiveness of the on -site storm water BMPs [RMP
Summary element of the Stormwater Management Strategy].
(d) a revieiv and comparison ofsample analytical data to benchmark values (if applicable)
over the past year, including a discussion about Tiered Response status. The
permittee shall use the Division's Annual Summary Data Monitoring Report (DP'IR)
form, available from the Stormwater Permitting Program's website (See'Monitoring
Forms' here: http:j ortal.ncderar.oi-g/web.�lr/npdes-stormwater).
The Director may notify the permittee when the SPPP does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall submit
a time schedule to the Director for modifying the SPPP to meet minimum requirements. The
permittee shall provide certification in writing (in accordance with Part III, Section B,
Paragraph 5) to the Director that the changes have been made.
10. SPPP Implementation. The permittee shall implement the Stormwater Pollution Prevention
Plan and all appropriate BMPs consistent with the provisions of this permit, in order to control
contaminants entering surface waters via stormkvater. Implementation of the SPPP shall
include documentation of all monitoring, measurements, inspections, maintenance activities,
and training provided to employees, including the log of the sampling data and of actions taken
to implement BMPs associated with the industrial activities, including vehicle maintenance
activities. Such documentation shall he kept on -site for a period of five (5) years and made
available to the Director or the Director's authorized representative immediately upon request.

or until this permit is revoked or rescinded. If the facility is monitoring monthly because of Tier Two
or Tier Three response actions under the previous General Permit, the facility shall continue a
monthly monitoring and reporting schedule in Tier Two or Tier Three status until relieved by the
provisions of this permit or the Division.
2 Grab samples shall be collected within the first 30 minutes of discharge. Where physical
separation between outfalls prevents collecting all samples within the first 30 minutes, the permittee
shall begin sampling within the first 30 minutes, and shall continue until completed.
3 Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless
representative outfall status (ROS) has been granted. A copy of the Division's letter granting ROS shall be kept
on site with the SPPP,
4 For each sampled measureable storm event, 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.
All analytical monitoring shall be performed during a measurable storm event.
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

The benchmark values in Table 3 and Table 4 are not enforceable permit limits. An exceedance of a
stormcvater benchmark value is not a permit violation; however, failure to respond to the exceedances
as outlined in this permit is a violation of permit conditions. The benchmarks are intended to reduce
polluted discharges by triggering the permittee's required response actions under Tiers One, Two, and
Three. See below the descriptions of Piers One, Two, and "[Three response actions.
Tier One
If: The first valid samDline results are above a benchmark value for anv narameter at anv outfalL
Then: `1The permittee shall:
1. Conduct a storm water management inspection within two weeks of receiving the sample results.
2. Identify and evaluate possible causes of the benchmark value exceedance.
3. Identify potential, and select the specific feasible: source controls, operational controls, or physical
improvements to reduce concentrations of the parameters of concern.
4. Implement the selected feasible actions within two months of the inspection.
5. Record each instance of a Tier One response in the SI'PP. Include the date and value of the
benchmark exceedance, the inspection date, the personnel conducting the inspection, the selected
feasible actions, and the date the selected feasible actions were implemented.
6. Note: Exceedances for a different parameter separately trigger the tiered response requirements.
Part II Page 7 of 10 Pages

I'ermit No. \,CG 190000
Tier Two
If: The first valid sampling results from two consecutive monitoring periods are above the benchmark values I
for anv specific parameter at a specific discharce outfall;
Then: The permittee shalL-
1. Repeat aii the required actions outlined above in "Pier One.
Z. 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 shall continue until three consecutive sample results are below the benchmark
values.
3. If no discharge occurs during the sampling period, the permittee is required to submit a monthly
monitoring report indicating "No Flow" to comply with reporting requirements.
4. Alternatively, in lieu of steps 2 and 3, the permittee may exercise the option of contacting the DEMLR
Regional Office Engineer as provided below in Tier Three, The Regional Office Engineer may direct the
response actions on the part of the permittee as provided in Tier Three. The permittee will be
considered to be obligated under the Tier Three provisions.
5. Maintain a record of the Tier Two response in the SPPP.
6. Continue Tier Two response obligations throughout the permit COC renewal process.
Tier Three
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 I)EM1.R
Regional Office Engineer in writing within 30 days of receipt of the fourth analytical results. DEMLR
may but is not limited to:
• require the permittee to revise, increase, or decrease the monitoring and reporting frequency for
some or all parameters, including requiring sampling of additional or substitute 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;
• require the permittee implement site modifications to qualify for a No Exposure Exclusion; or
• require the permittee to continue Tier Three obligations through the permit COC renewal process.
Failure to monitor and report Der the hermit terms may result in the Division reauirin
monthiv monitorine and renortine for all Darameters for a specified time'neriod. Lack of a
discharge from an outfall for the monitoring period, or inability to collect a sample because of
adverse weather conditions during a monitoring period will not constitute failure to monitor, as
long as those conditions are reported on the monitoring period DMR and noted in the SPPP. (See
Adverse 1,Veather in Definitions.) Similarly, sampling is not required outside of the facility's normal
operating hours.
However, if a facility is inactive for an extended period of time, the permittee must request, and
obtain, dormant site status from the DEMLR Regional Engineer in order to be excused from
sampling during the dormant period. The DEMLR letter granting dormant status must: be kept with
the SPPP, and available for inspection,
Part 11 Page 8 of 10 Pages

Permit No. NCG 190000
In the event that the Division releases the permittee from continued monthly monitoring and reporting
under Tier T wo or "Pier Three, DFMLR'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 all results from all valid discharge samples taken during each monitoring
period. 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.
SECTION C: QUALITATIVE MONITORING REQUIREMENTS
The purpose of qualitative monitoring is to implement a quick and inexpensive sway to evaluate the
effectiveness of the perminee's S1111P and to identify the potential for new sources of stormwater
pollution. Qualitative monitoring of stormcvater discharge outfalls must be performed during a
measurable storm event.
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status. Qualitative monitoring shall be performed as specified in Table 5 with
each required analytical monitoring event: whether semi-annual or more frequently as may be
subsequently required under Tier Two, Tier Three, or per the Qualitative Monitoring Response
requirements below. Inability to monitor because of adverse weather or lack of discharge during the
monitoring period must be documented in the SPPP and recorded on the Qualitative Monitoring
Report (see Adverse Weather in Definitions). Only stermiwater discharge outfalls (SDOs) discharging
stormwater associated with industrial activity must be monitored (See Definitions).
In the event an atypical condition is noted at an SDOs, the permittee shall document the suspected
cause of the condition and any actions taken in response to the discovery. This documentation will
be maintained with the SPPP.

during a measureable storm event. See Table 2 for schedule of monitoring periods. The permittee must
continue qualitative monitoring throughout the permit renewal process.
2 Monitoring Location: Qualitative monitoring shall be performed at each stormwater discharge outfall
(SDO) associated with industrial activity, regardless of representative outfall status (ROS).
A minimum of 60 days must separate monitoring dates, unless additional sampling has been
instituted as part of other analytical monitoring requirements in this permit.
if the permittee's qualitative monitoring indicates that existing stormwater BMPs are ineffective, or that
significant stormwater contamination is present, the permittee shall investigate potential causes, evaluate
the feasibility of corrective actions, and implement those corrective actions within 60 days, per the
Qualitative Monitoring Response, below. A written record of the permittee's investigation, evaluation,
and response actions shall be kept in the ST'PP.
Qualitative Monitoring Response
Qualitative monitoring is for the purposes of evaluating SPPP effectiveness, identifying the potential
for nc�v sources of stormwater pollution, and prompting the permit.t:ee'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, DEMLR
may but is not limited to:
• require that the permittee revise, increase, or decrease the monitoring frequency for some
or all parameters (analytical or qualitative),-
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures, -
require the permittee to perform upstream and do«vnstream monitoring to characterize
impacts on receiving waters; or
• require the permittee implement site modifications to qualify for a No Exposure Exclusion.

Technical Bulletin for N.C. General Stormwater
Permit NCG190000
Technical Bulletin for NCG 190000 Revised 6/04/2015
What activities are covered by this general permit?
NCG190000 allows stormwater discharges associated with activities classified as establishments primarily en-
gaged in: Operating Marinas [standard industrial classification (SIC) 44931 that provide vehicle maintenance
activities, and Ship and Boat Building and Repairing [SIC 3731; and like activities deemed by the Division of
Energy, Mineral, and Land Resources (1)EiNMLR) to be similar in the process and/or the exposure of raw materials,
products, by-products, or waste materials.
• This general permit does not authorize discharges at the facility containing waste streams including, but not lim-
ited to, bilge and ballast water, cooling water, sanitary wastes, power and hand washing, blasting, sanding, and
fish cleaning stations. A separate ivastewater permit may be required %w- these and other similar wastewater dis-
charges.
What are the key permit requirements?
• Implement a Stormwater Pollution Prevention Plan (SPPP) (Part 1I, Section A).
• Provide secondary containment for all bulk storage of liquid materials (Part II; Section A, 2.(b)),
• Perform, document, and report analytical and qualitative monitoring during a measurable storm event twice
each year. At the same time perform and document visual monitoring twice each year (Part I1, Section B 8: C).
What has changed since the last renewal?
• -Made it easier to sample during a measureable stor,n event (new term), rather than a representative storm event
(previous permit) (Part IV Definitions).
• Replaced Oil and Grease with a more specific `on -polar Oil S Grease test with a lower benchmark of la mg/L.
• Twice -per -year monitoring of pH is no longer required.
• Refinements and clarifications to the SPPP requirements (refer to Part 11, Section A).
• The permit allows forgoing sampling if adverse weather conditions prevent collection (Part, IV Definitions).
• Permittee is not required to obtain runoff samples outside of normal operating hours.
• A lower TSS benchmark of 50 mg/L for stormwater discharges into especially protected waters.
• New provisions for e-reporting (el) MR), once DEIMU capabilities for eDMR are established.
What are BMPs and why are they important?
A facility's Stormwater Pollution Prevention Plan should include Best :l'lanagement Practices (B- MPs) to control the
discharge of pollutants from all stormwater outfalls. BMPs include a variety of measures that help minimize the
potential for pollutants to enter stormwater that drains from a facility. There are different types of B1MPs:
Non-structural (practices or activities) BMPs include:
• Eliminating exposure of materials and equipment whenever possible by moving them to indoor locations.
• Practicing good housekeeping on -site. Handle and store materials at the facility in an orderly fashion.
• Exchanging hazardous materials for non -hazardous ones wherever possible.
• Establishing routine leak and maintenance checks to minimize any chance of spills occurring. Clean up all spills
immediately.
• Establishing bulk storage tank protocols that minimize the risk of spills during loading and unloading.
• \Maintaining wash pads and keeping them clear of paint chips, debris, and particles.
Structural (equipment or devices) f331Ps include:
• Containment dikes around the loading areas of bulk liquid storage containers.
• Roofs and secondary containment around materials so that they are not exposed to stormwater.
• Collection systems around boat wash areas to direct -,wash water to a holding tank or sanitary sewer.
• Converting from a liquid operation to a dry operation for hull maintenance and cleaning.
• Collection of debris from paint chips in boat maintenance areas to minimize contamination of stormwater.
• Hull maintenance practices that are performed on dry land as far away from the water as possible.

l PAGE TECHNICAL BULLETIN FOR N.C. GENERAL STORMWATER REVISED6104/2015 1
Frequently Asked Questions
Could I be exempt from a
NPDES stormwater permit?
Possibly. Facilities with industrial
activities subject to N111)ES storm -
water regulations that eliminate
all potential stormwater exposure
may be eligible for a No Exposure
Exclusion from a permit. Facili-
ties that meet, this condition may
apply by submitting a i\'o Exposure
Certification application (see link
below). Facilities must re -certify
"\, �oExposure" status every five
years.
What if I sell my business, or
the name changes?
This is a minor modification that
requires approval of DEMLR's di-
recLor before a permittee is ab-
solved of responsibility for the per-
mit. To request this change, com-
plete and submit a Name/
Ownership Change Forzn SWIJ-
239.
Do I have to monitor all the
outfal Is?
Yes. However, you may request
Representative Outfall Status
(ROS). If approved, this status
allows analytical monitoring at
fewer outfalls. To make this re-
quest, submit a ROS Request
Forrn.
Does a certified lab need to
analyze my samples?
.Monitoring under NPDES per-
mits must be conducted in accord-
ance with test procedures ap-
proved in federal regulations in
40 CFRy§136. All labs certified by
North Carolina perform analysis
in accordance with those proce-
dures. NSzhile N.C. certification
requirements do not apply to test-
ing stormwater-only discharges,
data gathered under an NPI)F.S
permit must still conform to fed -
era] requirements. using a North
Carolina certified lab is one way
to ensure compliance. A list of
certified labs is available from:
littp:H))orial.iie(lenr.org/web/w'q/
lab/cert/cerlabii sts
Can my boat wash water be
discharged to or with my
stormwater?
No. Boat wash water, whether
from hand washing or power wash-
ing, is considered wastewater.
This stormwater permit does not
authorize wastewater discharges.
Wastewater is not allowed to mix,
or be "diluted', with stormwater
for discharge at a stormwater out-
let unless permitted by a separate
wastewater permit. Once storm -
water commingles with
wastewater, it is all considered
wastewater and must be handled
as such.
A separate wastewater permit
is required in order to dis-
charge wastewater. Some possi-
ble alternatives (which may re-
quire an additional separate per-
mit) for minimizing wastewater
discharge to surface waters in-
clude: discharge to a municipal
kastewater treatment plant, water
recycling, conversion of activities
to dry processes which allow for
easy clean-up and maintenance
and proper disposal of waste gen-
erated from industrial activities.
The NCG190000 permit is applica-
ble to a marina that offers vehicle
maintenance service, which in-
cludes boat cleaning. It is not ap-
plicable for an individual washing
their own boat at a marina. How-
ever, it is highly encouraged that
facilities educate and monitor the
use of appropriate BMPs by boat
owners when washing their boats
to minimize potential impacts to
surface water.
Who inspects my site, and for what?
DEMLR regional office staff may visit the site to see if you have the permit, an acceptable SPPP, and that you
are following your SPPP. These inspections may be. routine or they may be the result of public complaints.
Please take compliance seriously! Facilities that violate stormwater permit conditions may be subject to fines.
Civil penalties of up to S25,000 per day may be assessed for each violation.

Was this a "Representative Storm Event" or "i`leasureable Storm Event" as defined by the permit?
(See information below.)
❑ Yes ❑ No
Please verify ivhether 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 E
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 ] 0 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 frorn the local DWQ Regional Office.
