physical features which may have a significant effect on the potential for the discharge of pollutantsto surface waters.
Date Description of Amendment/Update Authorized Signature

0 1. GENERAL INFORMATION
•
1.1 STORNIWATER DISCHARGE PERMIT
In North Carolina (NQ, coverage must be obtained under General Permit No. NCG 190000
(NCG 190) to discharge stormwater associated with operating Marinas, standard industrial
classification (SIC) 4493, and/or Ship and Boat Building and Repair. SIC 373, to surlace waters
under the National P011ulant Discharge Elimination System's (NPDES) program established
under the Clean Water Act (CWA). Part 11, Section A of the NCG190 requires the development,
maintenance and implementation of a Stormwater Pollution Prevention Plan (SPI'P). This
document shall serve as the SPPP for Dudley's Marina, Inc. A copy of this general permit has
been included as Appendix A and should be replaced once coverage has been obtained by the
State to ensure any specific requirements have been captured.
1.2 STORMWATER POLLUTION PREVENTION PLAN
A SPPP defines a program to control stormwater discharges from potential pollutant sources
identified at a specific facility. Additionally, a SPPP maps these potential pollutant sources that
are exposed to and may reasonably be expected to contribute to the contamination of stormwater
discharges. Potential pollutant sources usually generate from facility practices classified as
industrial activities. Such sources can include outdoor hazardous material storage areas, fueling
and maintenance areas and waste disposal practices exposed to stormwater.
Based on pollutant sources and exposures, best management practices (BMI's) are implemented
to either eliminate materials from stormwater exposure or provide adequate control to reduce
Pollutant discharges. BMPs may be either structural, such as secondary containment structures
for aboveground storage tanks (AS`I's), or non-structural, such as standard operating procedures
(SOPS) for maintenance and repair.
This plan shall be considered as the SPPP for Dudley's Marina, Inc. and must be reviewed in its
entirety and updated on an annual basis. At a minimum, updates shall include the following:
■ a list of significant spills and/or leaks of pollutants for the previous three (3) years, or
notation that no spills and/or leaks have occurred;
■ re -certification that stormwater outfalls have been evaluated for the presence of non-
stormwater discharges;
■ documentation of re-evaluation of on -site stormwater BMP effectiveness:
■ review and comparison of past year's monitoring data to benchmark values.
1of14

0 1.3 PROCEDURAL REQUIREMENTS
All requirements of the NC6190 must be met in order to maintain a compliant facility. The site
specific issued permit should be referenced for more detailed information. Requirements of the
general permit include the following:
■ Develop and implement a SPPP;
■ Conduct facility inspections;
■ Provide training to personnel;
■ .Identify facility personnel responsible for implementation of the SPPP
■ Implement a monitoring program
■ Update the SPPP annually;
■ Maintain the SPPP and reports included herein for a minimum period of 5-years.

3. POTENTIAL POLLUTANT SOURCES AND BMPS
Due to a marina's close proximity to waterways, there is a higher -potential for marina waters to
become contaminated from polluted stormwater runoff generated during various facility specific
activities such as boat cleaning, fueling operations, and boat maintenance. Runoff can be in the
form of sheet flow across generally flat areas or can be channeled into discernable conveyances,
ultimately discharging through outfalls into surface water.
Dudley's property can be divided into seven (7) separate drainage areas; each with its own
individual stormwater discharge outfall (SDO) point. Of these, three (3) contain practices that
can be considered as industrial activities and should therefore be included in the monitoring
program discussed in Section 5. Table 2 provides a list of facility specific practices, associated
potential pollutants as well as implemented good housekeeping practices and BMPS currently in
place. Additionally, drainage areas and facility practices have been identified on Figure 2,
3.1 SURFACE PREPARATION AND PAIWINC AcnVITIES
Hull maintenance, to include sanding, pressure washing and scraping, is a common practice at
marinas and aims to control fouling and -corrosion. Wastes generated from these practices can
contain metals, solvents and hydrocarbons. Boats are routinely removed from the water for hull
maintenance by the boat owner or their hired contractor or by marina staff. Dudley's Marina
prohibits the use of any detergents or additives in pressure wash water as well as any surface
preparation activities during windy conditions. Plastic sheeting and/or tarps are used where
possible to collect waste generated during these activities and the area is visually inspected and
cleaned at the end of surface preparation and painting activities. When possible, wash water
from pressure washing activities is collected and allowed to settle prior to discharging to grassy
areas. All paints and solvents used are mixed indoors to reduce the chance of spillage into the
environment. Materials are readily available for the immediate cleanup of drips and spills.

® 3.2 ENGINE MAINTENANCE, ANij REPAIRS
Boat engine repair and maintenance requires the use of many different materials, depending; on
the issue at hand. Dudley's Marina conducts engine maintenance at designated facility locations.
Materials used in these day-to-day operations such as solvents, antifreeze, acids, fuels and
lubricants, and batteries are stored indoors. These materials are only brought out during use and
returned to their inside storage locations following use. Rags used during maintenance, which
contain oils and solvents, are collected in on -site containers and picked up by an outside
contractor for cleaning and/or disposal.
In the event of rain, engine maintenance operations either cease or are moved to an indoor
location if possible. Limiting engine maintenance to dry weather conditions and maintaining
materials indoors prevents exposure to stormwater and therefore greatly reduced the likelihood
ofthese materials reaching surface waters.
3.3 MATERIAL HANDLING, TRANSFER, STORAGE AND DISPOSAL
Used Oil Tank
All hazardous material storage areas are located indoors to eliminate exposure to the elements
with the exception of the used oil, above ground storage tank (AST). Used oil from facility
maintenance activities is collected in a container located adjacent to the large bay doors of the
maintenance shop. The container is marked "Used Oil" and has a lid that remains closed when
not in use. To ensure that the container is used for its intended purpose, only marina personnel
are authorized to dispose of used only in the container. 'Ihe AST sits in a diked concrete
secondary containment structure that has more than sufficient space to contain 1 10% of the
container's contents in the event of total tank Failure. Personnel will move the container into the
maintenance shop in the event of potential flooding due to heavy rains, tropical storms and/or
hurricanes.
Rainwater accumulated in the secondary containment can be released to adjacent grassy areas if
found to be uncontaminated following a visual inspection. The secondary containment shall be
visually inspected for the presence of a sheen or other POL indicator. All inspections shall be
documented prior to releasing any accumulated rainwater from the secondary containment.
Under no circumstances should rainwater with a visible oily sheen be released from the
containment area. Records documenting accumulated rainwater release shall be maintained in
Appendix B fora period of live (5) years.
1- uclinl�
Dudley's Marina has four (4) dockside fueling areas and one (1) vehicle Fueling area. All fueling
areas are fed from centrally located underground storage tanks (USTs). The USTs are connected
to a Veeder-Root tank gauging system with a visual and audible alarm. Ullage reports are pulled
from the system and discussed with the fuel delivery contractor before any fuel deliveries are
8of1a

received. All fuel pumps are connected to an audible notification system inside the ship's store.
Before a patron can use a fuel pump, it must be turned on by a marina staff member. This allows
the marina to control use of the fueling stations and limits any misuse outside of normal
operating hours.
The vehicle fueling area is under a canopy and is protected from direct rainfall. Incidental spills
and drips are cleaned up with absorbent material as soon as they are observed. All stormwater
runoff from this area is collected in a bioretention basin which was voluntarily installed by the
facility owner. Dockside fueling areas are continuously monitored by personnel. A spill kit is
centrally located which allows for quick response in the event of an accidental release. Marina
patrons are discouraged to "top off" fuel tanks as this usually results in minor overflows and
spillage.
Snlirf Waste
Individual solid waste containers are located throughout the property and are enclosed within
wooden frame structures which keep the containers secure and eliminates the risk ofthem being
turned over. Solid waste from individual trash cans are transferred to a large, onsite dumpster.
Cans are emptied into the facility dumpster as needed, but no less, than once each day. Dempster
lids and doors remain closed whenever dumpsters are not in use. Marina personnel periodically
conduct visual inspections of solid waste containers to ensure hazardous materials are not being
improperly disposed of in the trash.
4. SPILL PREVENTION AND RESPONSE PROCEDURES
Everyday materials have the potential to contaminate stormwater runoff through spills and/or
exposure of materials. In order to reduce the potential for pollution, all staff members must
ensure that materials are properly maintained and disposed of. Additionally, any accidental
spills or releases of hazardous materials shall be contained and cleaned up in accordance with
this section.
A list of all significant spills and/or leaks occurring during the previous three (3) years shall be
maintained. Document information related to the spill on the Spill or Incident Reporting Form
and maintain a copy with the listing of`signifrcant spills. Additionally, it is recommended to take
inventory of and document the condition of spill response equipment on hand to ensure that the
facility is as prepared as possible in the event of an accidental release. Documentation of
significant spills and leaks and spill response equipment inventory shall be maintained in
Appendix C.
Dudley's Marina maintains and utilizes hazardous materials in very small, individual sized
quantities with the exception of gasoline, diesel fuel, and used oil. These three petroleum
products are the largest potential pollutant sources, with regard to stormwater contamination and
entering waterways.
9of14

['he SPPT identified in Table I is responsible for implementing these spill prevention and
response procedures. In addition to the implementation of response procedures, SPP"I' members
are responsible for conducting monthly inspections and maintaining inventory of spill response
equipment and educating fellow employees on these procedures.
Spill response priorities are as follows:
1. Stop the source of the release if it is safe to do so.
2. If spill is on land, prevent material from reaching surface waters.
3. If spill is in water, contain the spill so it doesn't spread.
4. Conduct clean-up operations.
Upon discovery of a petroleum spill on land or in the water immediately stop the source of the
release if safe to do so. If the spill is on land, prevent the product from entering waterways by
blocking waterway entry points. Use adsorbent pads, matting, booms and earthen dikes and
diversionary measures to contain spilled product.
If the spill occurs in the water use best judgement as to what measures shall be deployed (i.e.
absorbent pads, matting and/or boom). If spill is large, the boom shall be deployed to contain
product or deflect product to an isolated area where it can be collected.
If any danger to the health and/or safety ofemployees exists from the spill, only those methods
which would allow for minimum contact with the spill area will be undertaken.
Note: Fuel/Oil spills that reach surface waters must he immediately reported to both the
NCDEQ and the National Response Center (NRC).
A discharge of fuel/oil on land must be reported to the NCDEQ within 24 hours of the discharge
if any of the following apply:
• Volume discharged to land is 25 gallons or more
• Any amount discharged to land that is 100 feet or less from any surface water
• Volume discharged to land is less than 25 gallons and is not able to be cleaned up within
24-hours
Contact the identified contractor to perform clean-up procedures.- Document information on spill
response and maintain a copy of all spill records in this SPPP.

5. GOOD HOUSEKEEPING PRACTICES
Implementing good housekeeping; practices is a cost-effective way to maintain a clean and
orderly facility. Good housekeeping practices include establishing procedures to reduce the
likelihood of material and/or equipment mishandling, operation and maintenance schedules,
routine inspections, and a training program to ensure all staff members understand proper
procedures and to ensure continued implementation of these measures.
® Facility inspections are a requirement of the NCG 190 and are to be completed by a SPPT
member semi-annually, at a minimum. One inspection must be conducted during; the first half of
the year (January -June) and one during; the second half (July -December), with at least 60 days in
between. Facility inspections must be documented, including any planned or taken corrective
actions. Any deficiencies identified during; each inspection shall be elevated to the SPPM with
proposed corrective actions. Maintain a copy of these reports in Appendix D.
Providing proper initial training; as well as refresher training to all personnel is key for complete
implementation of stormwater management and pollution prevention practices. Training will be
provided to employees on an annual basis at a minimum. Document all training; in Appendix E.
6. MONITORING AND REPORTING
Each of the previously identified drainage basins have their own outfall points where the basin
discharges to surface waters, also known as the stormwater discharge outfall (SDO). Refer to
Figure 2 for a map of the drainage basins and associated SDOs. Per NCG 190 requirements, a
monitoring; program shall be established for conducting both analytical and qualitative
monitoring; Gom the three (3) industrial drainage areas.
Both analytical and qualitative monitoring; will be conducted twice per year; once from January —
June and once from July -December with a minimum of 60 days separating monitoring; events.
Sample collection shall take place during; a measureable storm event at each SDO from drainage
areas with industrial practices. Table 3 lists all SDOs to be included in the monitoring program.

(DWR) within 30 days of receiving the sampling results from the laboratory. If no discharge
occurs during any sampling period, document "No Flow" on the DMR. Maintain a copy of all
analytical results and DMRs in Appendix F.
6.2 QUALITATIVE MONITORING
Qualitative monitoring is subjective and provides a quick, inexpensive way to evaluate sources
of stormwater pollution by conducting a visual inspection. Qualitative monitoring will be
conducted by a SPPT member at the same SDOs which require analytical monitoring.
Qualitative monitoring can be conducted at the same time analytical samples are being collected
and should be visually inspected for the following characteristics:
■ Color
■ Odor
■ Clarity
■ Floating Solids
■ Suspended Solids
■ Foam
■ Oil Sheen
■ Erosion or deposition at the outfall
■ Other obvious indicators of stormwater pollution
Document visual inspection on the SDO Qualitative Monitoring Report included in Appendix G.
A copy of the State guidance document,' SDO Qualilwive Monitoring Reporl .Supplemeni SWU-
242a: Gui(lance fi)r Rolit g ,Slormuwter Discharge, has been included in Appendix G for
reference.
Any instances that stormwater contamination is present shall be investigated for potential
cause(s). If a potential cause can be identified, Dudley's Marina shall evaluate the feasibility of
® corrective actions and implementation of those corrective actions within 60 days. All findings
from these investigations shall be documented and maintained in the SPIT.
13 of 14

0 6.3 NON-STORMWATER DISCIIARGES
In addition to the analytical and qualitative monitoring, all SDOs will be evaluated for the
presence of non-stormwater discharges. At least annually, an SPPT member will visually inspect
each SDO, during a dry weather period, for any flows. Dudley's Marina is not permitted for any
other discharges, therefore there should not be flow from any SDO during dry weather. If non-
stormwater discharges are observed, the SPPT member must investigate to determine the source.
Complete the Non-Stormwater Discharge Certification after each annual evaluation and maintain
a signed copy in Appendix H far the life ofthe permit.
6.4 MONITORING, REPORTING AND RECORDKEEPING
A copy of all analytical monitoring results and monitoring event documentation, to include
submitted DMRs, shall be maintained in Appendix F for the life of the permit. Qualitative
monitoring documentation shall be maintained in Appendix G. Reporting and recordkeeping
requirements for both analytical and qualitative monitoring are summarized below:
• Semi -Annual, Analytical Monitoring:
o Complete a DMR (form SWU-253-060515) upon receipt of sampling results
a Submit completed DMR to the state within 30 days from the date sampling
results are received;
o Complete a SDO Annual Summary DMR Report (form SWU-250NCG19-
OP 060815) following the completion of both analytical sampling events per each
calendar year;
o ' Submit completed SDO Annual Summary DMR Report to the state
o Maintain a copy of the laboratory sampling results, completed chain of custody
forms and submitted DMRs in Appendix F.
• Semi -Annual, Qualitative Monitoring:
o Complete a SDO Qualitative Monitoring Report (form SWU-242) for each
evaluated outfall;
o Maintain a copy of all SDO Qualitative Monitoring Reports in Appendix G;
o Qualitative monitoring results should only be submitted to the State when
specifically requested.

PART I INTRODUCTION 40
SECTION A: GENERAL PERMIT COVERAGE
All persons desiring to be covered by this General Permit must register with the Division of Energy,
Mineral, and Land Resources by the filing of a Notice of Intent (1101) 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 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
from permitting must 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 recertify the No Exposure Exclusion annually.
Any facility may apply for new or continued coverage under this permit until a Total Maximum
Daily Goad (TMDL) for pollutants for stormwater discharges is established. A TMDL sets a
pollutant -loading limit that affects a watershed, or portion of 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 1.80 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.I. A list of approved
TMDLs for the state of North Carolina can be found at

is public information in accordance with Part I11, Section E, 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 be 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 descri tion of storage practices, loading and unloading activities, outdoor
() P g P g g
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 outfall; direction
of flow in each drainage area; industrial activities occurring in each drainage area;
buildings; stormwater Best Management Practices (BMPs); 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-
stormwater discharges are present, the permittee shall identify the source and record whether
Part II Page 1 of 10

Permit No. NCG 190000
the discharge is otherwise 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 B, paragraph 5.
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 Stormwater 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: bulk storage of liquid materials including petroleum products; storage in any
amount of Section 313 of Title I II of the Superfund Amendments and Reauthorization Act
(SARA) water priority chemicals; and storage in anv amount of hazardous substancesin
order to prevent leaks and spills from contaminating stormwater runoff. A table or
summary of all such tanks and stored materials and their associated secondary containment
areas shall be maintained. If the secondary containment devices are connected to
stormwater conveyance systems, the connection shall be controlled by manually activated
valves or other similar devices, which shall be secured closed with a locking mechanism.
Any stormwater that accumulates in the containment area shall beat a minimum visually
observed for color, foam, outfall staining, visible sheens, and dry weather now, 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 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
(BMPs) 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

Pennit 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 be a component of the SPRP, but may not he 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 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.
DEMLR 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, % 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."
S. 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, all 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,
b. 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 outfalls required
in Part 11 B, C, and D of this permit.
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. The annual training shall be documented by 10
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

® abrasives, disposal of vessel wastewaters, fueling procedures, sanding, painting and blasting
procedures, and used battery management.
C�
8. 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 be 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 of significant 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 written re -certification that the stormwater outfalls have been evaluated for the
presence of non-stormwater discharges (element of the Site Overview);
(c) a documented re-evaluation of the effectiveness of the on -site stormwater BMPs (BMP
Summary element of the Stormwater Management Strategy).
(d) a review and comparison of sample 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 (DMR)
form, available from the Stormwater Permitting Program's website (See'Monitoring
Forms' here: htt�):j/12ortai.ncdenr.ot-glweb/IrJnpdes-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 stormwater. 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 be kept on -site for a period of five (S) years and made
available to the Director or the Director's authorized representative immediately upon request.

1 Measurement Frequency: Twice per year (unless other provisions of this permit require monthly
sampling) during a measureable storm event, until either another permit is issued for this facility
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
obtains approval from the local DEMLR Regional Office. See Definitions.

1 Maintain semi-annual monitoring during permit renewal process. If at the expiration of the general
permit, the permittee has submitted an application for renewal of coverage before the submittal
deadline, the permittee will be considered for renewed coverage. The applicant must continue semi-
annual monitoring until the renewed Certificate of Coverage is issued.
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 six-month sampling period.
In all cases, the permittee shall report the analytical results from the first sample with valid results
within the monitoring period. The permittee shall compare those results to the benchmark values in
Table 3 or Table 4. 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.

The benchmark values in Table 3 and Table 4 are not enforceable permit limits. An exceedance of a
stormwater 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 Tiers One, Two, and Three response actions.
11
Tier One
! If: The first valid sampling results are above a benchmark value for any parameter- at any outfall; I
Then: The permittee shall:
1. Conduct a stormwater 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.
S. Record each instance of a Tier One response in the SPPP. 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 11 Page 7 of 10 Pages

is
Permit No. NCG 190000
Tier Two
If: The first valid sampling results from two consecutive monitoring periods are above the benchmark values
for anv specific parameter at a specific discharge outfall;
Then: The permittee shall:
1. Repeat all the 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 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.
S. 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 DEMLR
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
monthly monitorine and renortine for all Darameters for a sDecified time period. 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 Weather 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 lI Page 8 of 10 Pages

Permit No. NCG190000
In the event that the Division releases the permittee from continued monthly monitoring and reporting
under Tier Two or Tier Three, DRMLR'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 way to evaluate the
effectiveness of the permittee's SPPP and to identify the potential for new sources of stormwater
pollution. Qualitative monitoring of stormwater 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 stormwater 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.

1 Monitoring Frequency: Twice per year (unless other provisions of this permit prompt other frequency)
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 SPPP.
Qualitative Monitoring Response
Qualitative monitoring is for the purposes of evaluating SPPP effectiveness, identifying the potential
for new sources of stormwater pollution, and prompting the permittee's response to pollution. if
the permittee repeatedly faits 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 downstream 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
What activities are covered by this general permit?
Revised 6104/2015
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 (DEMLR) to be similar in the process and/or the exposure of raw materials,
products, by-products, or waste materials.
• TMs general perntit does not arr.thorize discharges at the facility containing waste streants including, but riot lim-
ited to, bilge and ballast water, cooling water, sanitary wastes, power and hand washing, blasting, sanding, and
fish cleaning stations. A separate wastewater permit rnay be required for these and other sintilar wastewater dis-
charges.
What are the key permit requirements?
• Implement a Stormwater Pollution Prevention Plan (SPPP) (Part 11, 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 II, Section B & Q.
What has changed since the last renewal?
• Made it easier to sample during a rneasureable storm event (new term), rather than a representative storm. event
(previous permit) (Part 1V Definitions).
• Replaced Oil and Grease with a more specific Non -polar Oil & Grease test with a lower benchmark of 15 mg/L.
• Twice -per -year monitoring of pH is no longer required.
• Refinements and clarifications to the SPPP requirements (refer to Part II, Section A).
• The permit allows forgoing sampling if adverse weather conditions prevent collection (Part 1V Definitions).
• Permittee is not required to obtain runoff samples outside of normal operating hours.
• A lower TSS benchmark of 50 mg1L for stormwater discharges into especially protected waters.
• New provisions for e-reporting (eDMR), once DEMLR capabilities for eQMRare established.
What are BMPs and why are they important?
A facility's Stormwater Pollution Prevention Plan should include Best Management Practices (BMPs) 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 BMPs:
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) BMPs include.
j • 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 frir away from the water as possible.

Frequently Asked Questions
Could I be exempt from a
NPDES stormwater permit?
Possibly. Facilities with industrial
activities subject to NPDES 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 No Exposure
Certification application (see link
below). Facilities must re -certify
"No "No Exposure" status every five
years.
What if I sell my business, or
the name changes?
`Phis is a minor modification that
requires approval of DEMLR's di-
rector before a permittee is ab-
solved of responsibility for the per-
mit. To request this change, com-
plete and submit a Narne/
Ownership Change Form SWU-
239.
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 make this re-
quest, submit a ROS Request
Forst.
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 CFR §136. All labs certified by
North Carolina perform analysis
in accordance with those proce-
dures. While N.C. certification
requirements do not apply to test-
ing stornuvater-only discharges,
data gathered under an NPDES
permit must still conform to fed-
eral requirements. Using a North
Carolina certified lab is one way
to ensure compliance. A list of
certified labs is available from:
httl)://I)ortal.nedenr.or•g/web/wq/
lab/cent/cerlablists
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
wastewater 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 $25,000 per day may be assessed for each violation.

water Permitting Program's web -

All permits require qualitative monitoring to 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 72-11our 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 DEMLR
Regional Office.

Guidance for Rating Stormwater Discharge
This supplement is intended only as a guide for rating visually observed parameters on a scale of
1-5. The inspector should use best professional judgment when characterizing the quality of
stormwater discharge. Also, the pictures included here do not necessarily show stonnwater
discharges but serve to illustrate the characteristics described.

Water naturally high in tannins in the eastern part of North Carolina may still have low amounts
of suspended solids and high clarity but not appear "clear" because of coloration. The examples
below will help rate discharges that must be observed in tannic waters.
Clear tannic water may look like tea or coffee, but waters that look more "milky" or like
"chocolate milk" have less clarity and higher suspended solids.
