Subject: NPDES Stormwater Permit Coverage Renewal
S T G Transport - Shipyard Blvd
COC Number NCGO80218
New Hanover County
In response to your renewal application for continued coverage under stormwater General Permit NCG080000
the Division of Water Quality (DWQ) is forwarding herewith the reissued 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 (COC)
• A copy of General Permit NCGO80000
• A copy of the Technical Bulletin for the General Permit
• Two copies of the Discharge Monitoring Report (DMR) Form
• Two copies of the Qualitative Monitoring Report Form
The General Permit authorizes discharges of stormwater, and it specifies your obligations for discharge
controls, management, monitoring, and record keeping. Please review the new permit to familiarize yourself
with all the changes in the reissued permit. Your facility has six (6) months from the time of receipt of the
permit to update your current SPPP to reflect all new permit requirements.
The first sample period of your permit begins January 1, 2013. Your facility must sample a "measureable
storm event" beginning during the periods beginning January 1 and July 1 of every year (or, if applicable,
report "No Flow," as outlined in Part III, Section E). Also, please note that Tier 3 Actions in Part II of your
permit are triggered by benchmark exceedances on four occasions beginning on the effective date of this
permit and do not count prior exceedances.
The more significant changes in the General Permit since your last COC was issued are noted either in the
Draft Permit Fact Sheet that accompanied the public notice (httR:fportal.ncdenr.org/web/wg/ws%suZcurrent-
notices), or in the Response to Comments / Summary of Changes and Technical Bulletin documents that are
posted on the Stormwater Permitting Unit's website with the new General Permit. Please visit
http://oortal.ncdenr.org/web/wgLws,tsi!lnj2dessw (click on 'General Permits' tab) to review that information
for your specific General Permit carefully.

Some of the changes include:
Part II:
• Section A: The Stormwater Pollution Prevention Plan (SPPP) section, if applicable, has been updated
to the most current language of our permits. Additional conditions for specific industry sectors have
been added to the 5PPP requirements in some cases.
• Sections 8, C: Failure to perform analytical stormwater monitoring may result in the Division requiring
that the permittee begin a monthly sampling scheme.
• Sections 8, C: A lower TS5 benchmark of 50 mg/I for HOW, ORW, PNA and Tr Waters applies to these
more sensitive waters.
• Sections 8, C. The monitoring parameter Oil & Grease.(0&G) has been replaced by the parameter
Total Petroleum Hydrocarbons (TPH) for vehicle maintenance areas, and in some cases, other
analytical monitoring requirements.
• Sections 8, C, D: Inability to sample due to adverse weather must be recorded in the SPPP, or in
separate on -site records if your General Permit does not require an SPPP. Adverse weather is defined
in the "Definitions" section of the permit.
• Sections 8, C. The term "Representative Storm Event" has been replaced by "Measurable Storm
Event." A measurable storm event is defined in the permit.
• Section D: If the permittee fails to respond effectively to problems identified by qualitative
monitoring, DWQ may require the permittee to perform corrective action.
Please review Parts III and IV to understand the Standard Conditions of your new NPDES General Permit,
including Compliance and Liability, Reporting, Monitoring and Records requirements; Operation and
Maintenance obligations; and Definitions. Please note that all samples analyzed in accordance with the terms
of this permit must be submitted to the Division on Discharge Monitoring Report (DMR) forms available on
the Stormwater Permitting Unit's website above. DMR forms must be delivered to the Division no later than
30 days from the date the facility receives the sampling results from the laboratory. Also note that existing
permittees do not need to submit a renewal request prior to expiration unless directed by the Division.
Your coverage under the General Permit is transferable only through the specific action of DWQ. This permit
does not affect the legal requirements to obtain other permits which may be required by DENR, nor does it
relieve the permittee from responsibility for compliance with any other applicable federal, state, or local law,
rule, standard, ordinance, order, judgment, or decree. If you have any questions regarding this permit
package, please contact the Division's Stormwater Permitting Unit at [phone].
Sincerely,
for Charles Wakild, P.E.

North Carolina Division of Water Quality Response to Comments and
Summary of Final Changes to NPDES Stormwater General Permit NCGO80000
(2012 Renewal)
Background
NPDES General Permit NCGO80000 regulates stormwater discharges associated with activities that
have Vehicle Maintenance Areas (including vehicle rehabilitation, mechanical repairs, painting,
fueling, lubrication and equipment cleaning operation areas) associated with activities classified as
Rail Transportation [Standard Industrial Classification (SIC) 401, Local and Suburban Transit and
Interurban Highway Passenger Transportation [SIC 411, Motor Freight Transportation and
Warehousing [SIC 42], except Public Warehousing and Storage [SIC 4221-4225], Postal Service [SIC
43], and Petroleum Bulk Stations and Terminals [SIC 5171] with total petroleum storage capacity of
less than 1 million gallons.
NPDES General Permit NCG080000 expired on October 31, 2012. The North Carolina Division of
Water Quality (DWQ) announced in selected newspapers across the State on or about September
1, 2012 that the draft of the proposed renewal General Permit would be posted on our website for
public comment. DWQ also ran this notice in the North Carolina Register the same month; on the
Stormwater Permitting Unit website in September 2012; as well as in renewal letters to all affected
permittees.
DWQ revises and reissues NPDES stormwater General Permits on a five-year schedule. Every
five years we review collected analytical data from the previous five-year term of the permits;
evaluate identified compliance problems and problems in our enforcement of the permits; and
seek to improve the effectiveness of the permits as Stormwater management tools for the
permittees.
The draft NCGO80000 permit and Fact Sheet were posted to the Stormwater Permitting Unit's
website on September 1, 2012. The public comment period was scheduled to close on October
1, 2012 and was extended to October gth to compensate for the delay in some newspaper
notice publish dates. During this time, DWQ staff received comments on this proposed draft
General Permit NCG080000. The Division received public comments about proposed draft
general permits for other industrial sectors expiring at the same time, and some of those
comments have been addressed in the final NCGO80000 permit for consistency.
EPA Region IV staff in Atlanta was sent the draft General Permit on September 4, 2012. On
September 17, 2012, EPA Region IV responded that the agency concurred with no comments.
€PA's additional review and approval would be necessary if the proposed final General Permit
incorporated significant changes from the draft or if significant public comments objecting to
the permit were received. DWQ concluded that neither of these criteria was met and
therefore, further EPA review is not required.
DWQ prepared this summary document both for those interested parties that submitted
written comments on draft General Permits proposed at the same time, as well as for other

interested parties. This document will be posted on our website for public access.
Comments and Responses
Waste Management's Comment 1: Waste Management expressed concern that the permit
conditions and the SPCC requirements pursuant to 40 CFR Part 112 were redundant.
Response: Under 2.b., DWQ added the following language, "For facilities subject to a federal oil
Spill Prevention, Control, and Countermeasure (SPCC) plan, any portion of the SPCC plan fully
compliant with the requirements of this permit may be used to demonstrate compliance with
this permit."
Waste Management's Comment 2: Waste Management expressed concern that site conditions
made 'collecting samples within the first 30 minutes of discharge unrealistic and unachievable.
Response: Under Part II Section B Footnote 2, DWQ revised the language to state, "Sample
collection must begin within the first 30 minutes of discharge and continue to all outfalls until
completed."
Waste Management's Comment 3: Waste Management expressed concern that the permit did
not effectively address sampling during adverse weather conditions.
Response: The following language was added, "The permittee shall complete the analytical
samplings in accordance with the schedule specified in Table 2, unless adverse weather
conditions prevent sample collection (see Adverse Weather in Definitions)."
Waste Management's Comment 4: While the permit authorizes discharges from oil water
separators and/or petroleum bulk stations and terminals, Waste Management expressed
concern that many local ordinances prohibit surface water discharges from oil water
separators.
Response: DWQ revised the language to read "...unless otherwise prohibited, the permittee is
authorized to discharge stormwater from oil water separators..."
Also, DWQ added the following clarification, "The limitations in Table 4 only apply to oil water
separators, secondary containment structures at petroleum bulk stations and terminals with a total
petroleum storage capacity of less than 1 million gallons, or other stormwater discharges that have
been specifically designated by the Division as subject to these discharge requirements in the permit.
This means that, unless specified differently by the Division, discharges from oil/water separators or
from secondary containment areas that are associated with vehicle maintenance activities at facilities
categorically captured by the federal NPDES Stormwater Program are otherwise subject to Part 11.,
Section B. (Stormwater Analytical Monitoring Requirements) of this general permit."

October 25, 2012
Response to Comments on Draft NPDES General Permit NCGO80000 —Vehicle Maintenance Areas
_Waste Management's Comment 5: Waste Management expressed concern that Table 5
footnotes did not address procedures should there not be a measurable storm event during
normal operating hours.
Response: DWQ added the following language, "Qualitative monitoring is not required outside
of the facility's normal operating hours."
Summary of Permit Changes
DWQ made other changes to the draft permit before finalizing. These changes were also
minor, and DWQ concluded additional notice and/or EPA review was not necessary. The
changes (in addition to those discussed above) were:
1. Cover: The following language added for clarification, "Discharge limitations in Part 11, Section C., only
apply to such activities when designated by the Division."
2. Part II Monitoring, Controls, and Limitations for Permitted Discharges, Section A: 2,13., the following
language added for clarification, "For facilities subject to..a federal oil Spill PreKentio_n, Control, and
Countermeasure {SPCD plan, any portion o,f_the.SP.CC.plan fully compliant with the requirements of
this permit may be used to demonstrate compliance with this permit."
3. Part Il Monitoring, Controls, and Limitations for Permitted Discharges, Section B, Table 1 Footnote 2,
revised language to, "Sample collection must begin within the first 30 minutes of discharge and
continue to all outfalls until completed."
4. Part II Monitoring, Controls, and Limitations for Permitted Discharges, Section B, Table 1 Footnote 3,
added following language, "A copy of the DWQ letter granting ROS must be kept on site. DWQ's ROS
letter remains in effect through the subsequent reissuance of this permit and as long as the pertinent
site conditions and operations remain unchanged, unless the ROS letter provides for other conditions
or duration."
5. Part II Monitoring, Controls, and Limitations for Permitted Discharges, Section B, added following
language, "The permittee shall complete the analytical samplings in accordance with the schedule
specified in Table 2, "unless adverse weather conditions prevent sample collection (see Adverse
Weather in Definitions)" .... "Sampling is not required outside of the facility's normal operating
hours."
6. Part II Monitoring, Controls, and Limitations for Permitted Discharges, Section B, revised language,
"Failure to monitor semi-annually per permit terms may result in the Division requiring monthly
monitoring for all parameters for a specified time period. "No discharge" from an outfall or inability to
collect a sample because of adverse weather conditions during a monitoring period does not
constitute failure to monitor, as long as it is properly reported."

October 25, 2012
Response to Comments on Draft NPDES General Permit NCGO80000 —Vehicle Maintenance Areas
7. Part II Monitoring, Controls, and Limitations for Permitted Discharges, Section B, added following
language, "In the event that DWQ releases the permittee from continued monthly monitoring under
Tier Three, DWQ's release letter remains in effect through the subsequent reissuance of this permit,
unless the release letter provides for other conditions or duration.
8. Part II Monitoring, Controls, and Limitations for Permitted Discharges, Section B, Revised Table 3 to:

the pH of the precipitation (within instrument accuracy) instead of 6 S.U. Readings from an on -
site or local rain gauge (or local precipitation data) must be documented to demonstrate
background concentrations were below the benchmark pH range of 6-9."
Part 11 Monitoring, Controls, and Limitations for Permitted Discharges, Section C, clarified
language, "if such activities have been designated by the Division, discharges shall be monitored
and limited as specified in Table 4, and sampled in accordance with the schedule presented in
Table 2, and added the following language, "The limitations in Table 4 only apply to oil water
separators, secondary containment structures at petroleum bulk stations and terminals with a
total petroleum storage capacity of less than 1 million gallons, or other stormwater discharges
that have been specifically designated by the Division as subject to these discharge requirements
in the permit. This means that, unless specified differently by the Division, discharges from
oil/water separators or from secondary containment areas that are associated with vehicle
maintenance activities at facilities categorically captured by the federal NPDES Stormwater
Program are otherwise subject to Part IL, Section S. (Stormwater Analytical Monitoring
Requirements) of this general permit."

10. Part II Monitoring, Controls, and Limitations for Permitted Discharges, Section C, revised footnote 2
to, "Sample collection must begin within the first 30 minutes of discharge and continue to all outfalls
until completed."
11. Part II Monitoring, Controls, and Limitations for Permitted Discharges, Section C, added language to
footnote 3, "A copy of the DWQ letter granting ROS must be kept on site. DWQ's ROS letter remains
in effect through the subsequent reissuance of this permit and as long as the pertinent site conditions
and operations remain unchanged, unless the ROS letter provides for other conditions or duration."
12. Part II Monitoring, Controls, and Limitations for Permitted Discharges, Section D, added language,
"Qualitative monitoring is not required outside of the facility's normal operating hours."
Conclusion
DWQ's overall intent in proposing changes to the General Permit has been to provide permit
requirements that will encourage industrial permittees to respond with prompt corrective
action to the discovery of pollutant discharges in excess of the benchmark values. DWQ
incorporated comments on the proposed draft General Permit NCG08D000 as well as
comments regarding other proposed general permits, as appropriate, as indicated above.

PART I INTRODUCTION
SECTION A: GENERAL PERMIT COVERAGE
All persons desiring to have facilities 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 N01 shall be
submitted and a certificate of coverage issued prior to any point source discharge of stormwater
associated with industrial activity to the surface waters of the state.
Any owner or operator not wishing to be covered or limited by this General Permit may make
application for an individual NPDES permit in accordance with NPDES procedures in 1SA NCAC 2H
.0100, stating the reasons supporting the request. Any application for an individual permit should
be made at least 180 days prior to commencement of discharge.
This General Permit does not cover activities or discharges covered by an individual NPDES permit
until the individual permit has expired or has been revoked. Any person conducting an activity
covered by an individual permit but which could be covered by this General Permit may request
that the individual permit be revoked and coverage under this General Permit be provided.
If industrial materials and activities are not exposed to precipitation or runoff as described in 40
CFR §122.26(g), the facility may qualify for a No Exposure Exclusion from NPDES stormwater
discharge permit requirements. Any owner or operator wishing to obtain a No Exposure Exclusion
must submit a No Exposure Certification Notice of Intent (NOI) form to the Division; must receive
approval by the Division; must maintain no exposure conditions unless authorized to discharge
under a valid NPDES stormwater permit; and must recertify the No Exposure Exclusion annually.
Any facility may apply for new or continued coverage under this permit until a Total Maximum
Daily Load (TMDL) for pollutants for stormwater is established. A TMDL sets a pollutant -loading
limit that affects a watershed, or portion of a watershed, draining to a specific impaired water. For
discharges to watersheds affected by a TMDL, coverage under this permit may depend on the
facility demonstrating it does not have reasonable potential to violate applicable water quality
standards for those pollutants as a result of discharges. If DWQ determines that discharges have
reasonable potential to cause water quality standard violations, the facility shall apply for an
individual permit 180 days prior to the expiration date of this General Permit. Once that individual
permit is effective, the facility will no longer have coverage under this General Permit. Note that the
permittee 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, Part 11,
Section A.
During the period beginning on the effective date of the permit and lasting until expiration, the
permittee is authorized to discharge stormwater associated with industrial activity. Such
discharges shall be controlled, limited, and monitored as specified in this permit.
Part I Page 1 of 2

Permit No. NCG080000
SECTION B: PERMITTED ACTIVITIES
Until coverage under this permit expires or is modified or revoked, the permittee is authorized to
discharge stormwater to the surface waters of North Carolina or separate storm sewer system
which has been adequately treated and managed in accordance with the terms and conditions of
this General Permit.
Any other point source discharge to surface waters of the state is prohibited unless it is an
allowable non-stormwater discharge or is covered by another permit, authorization or approval.
The stormwater discharges allowed by this General Permit shall not cause or contribute to
violations of Water Quality Standards.
This permit does not relieve the permittee's responsibility for compliance with any other applicable
federal, state, or local law, rule, standard, ordinance, order, or decree,
Part I Page 2 of 2

Permit No. NCG080000
PART 11 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 111, Standard Conditions, Section E, paragraph 3 of this
permit. The SPPP shall include, at a minimum, the following items:
D/1"s-ite 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:
V%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 accurate 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.
G/ 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 and finished grade; 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.
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. The
certification statement will be signed in accordance with the requirements found in Part Ill,
Standard Conditions, Section B, Paragraph S.
Part it Page l of 10

Permit No. NCGO80000
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:
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 run-on 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 run-on
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
111 of the Superfund Amendments and Reauthorization Act (SARA) water priority chemicals;
and storage in any amount of hazardous substances, in order to prevent leaks and spills
from contaminating stormwater runoff. A table or summary of all such tanks and stored
materials and their associated secondary containment areas shall be maintained. If the
secondary containment devices are connected to stormwater conveyance systems, the
connection shall be controlled by manually activated valves or other similar devices (which
shall be secured closed with a locking mechanism). Any stormwater that accumulates in the
containment area shall be at a minimum visually observed for color, foam, outfall staining,
visible sheens and dry weather flow, prior to release of the accumulated stormwater.
Accumulated stormwater shall be released if found to be uncontaminated by any material.
Records documenting the individual making the observation, the description of the
accumulated stormwater, and the date and time of the release shall be kept for a period of
five (5) years.
For facilities subject to a federal oil Spill Prevention, Control, and Countermeasure (SPCC)
plan, any portion of the 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.
d. Locomotive Sanding Areas (applicable to Rail Transportation only). The plan must
describe measures that prevent or minimize contamination of the stormwater runoff from
areas used for locomotive sanding. The facility shall consider covering sanding areas,
minimizing stormwater runon/runoff, appropriate sediment removal practices to minimize
the offsite transport of sanding material by stormwater, or other equivalent measures.
e. Vehicle and Equipment Cleaning Areas. The plan must describe measures that prevent
or minimize contamination of the stormwater runoff from all areas used for vehicle and
equipment cleaning. The facility shall consider performing all cleaning operations indoors,
covering the cleaning operation, ensuring that all wash waters drain to the sanitary sewer
Part II Page 2 of 10

Permit No. NCC080000
system (i.e., not the stormwater drainage system, unless permitted by another NPDES
general or individual permit), collecting the stormwater runoff from the cleaning area and
providing treatment or recycling, or other equivalent measures. If sanitary sewer is not
available to the facility and cleaning operations take place outdoors, the cleaning operations
shall take place on grassed or graveled areas to prevent point source discharges of the wash
water into the storm drains or surface waters. Where cleaning operations cannot be
performed as described above and when operations are performed in the vicinity of a storm
drainage collection system, the drain shall be covered with a portable drain cover during
cleaning activities. Any excess ponded water shall be removed and properly handled by
pump to a sanitary sewer system prior to removing the drain cover. Detergents used
outdoors shall be biodegradable and the pH adjusted to be in the range of 6 to 9 standard
units. The point source discharge of vehicle and equipment wash waters, including tank
cleaning operations, are not authorized by this permit and must be covered under a
separate NPDES general or individual permit or discharged to a sanitary sewer in
accordance with applicable industrial wastewater pretreatment requirements.
f. Remote Fueling Operations. If remote fueling (or other vehicle maintenance activities)
are conducted at off site locations but coordinated from the permitted facility, the plan shall
include a component that describes the stormwater management practices and BMPs used
to prevent and/or minimize the contamination of stormwater from such activities.
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
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. 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.
5. 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 facility personnel responsible for
Part 11 Page 3 of 10

Permit No. NCC080000
implementing the training shall be identified, and their annual training shall be documented by
the signature of each employee trained.
6. 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.
7. SPPP Amendment and Annual Update. 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. All aspects of the SPPP shall be reviewed and updated on an
annual basis. The annual update shall include:
(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 far 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 Unit's website (See
'Monitoring Forms' here: http:/lportal.ncdenr.org/web/wq/ws/su/npdessw).
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 I11, Standard
Conditions, Section B, Paragraph 5) to the Director that the changes have been made.
Facility Inspection Program. Inspections of the facility and all stormwater systems shall
occur 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). The inspection and any subsequent
maintenance activities performed shall be documented, recording date and time of inspection,
individual(s) making the inspection and a narrative description of the facility's stormwater
control systems, plant equipment and systems. Records of these inspections shall be
incorporated into the Stormwater Pollution Prevention Plan. These facility inspections are
different from, and in addition to, the stormwater discharge characteristic monitoring required
in Part lI of this permit.
9. SPPP Implementation. The permittee shall implement the Stormwater Pollution Prevention
Plan and all appropriate BMPs to prevent contaminants from 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 (5) years and made available to the Director or the Director's
authorized representative immediately upon request.

Permit No. NCGO80000
SECTION B: ANALYTICAL MONITORING REQUIREMENTS - VEHICLE MAINTENANCE ACTIVITIES
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1, for those
facilities conducting vehicle maintenance activities and utilizing more than S5 gallons new motor oil per
month when averaged over the year (those vehicle maintenance activities not utilizing more than 55
gallons of new motor oil per month are not required to conduct analytical monitoring).

Footnotes:
1 Measurement Frequency: Twice per year during a measureable storm event.
2 Sample collection must begin within the first 30 minutes of discharge and continue to all outfalls until
completed.
3 Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless
representative outfali status (ROS) has been granted. A copy of the DWQ letter granting ROS must be
kept on site. DWQ's ROS letter remains in effect through the subsequent reissuance of this permit and as
long as the pertinent site conditions and operations remain unchanged, unless the ROS letter provides
for other conditions or duration.
4 For each sampled measureable storm event the total precipitation must be recorded. An on -site rain
gauge or local rain gauge reading must be recorded.
All analytical monitoring shall be performed during a measurable storm event at each stormwater
discharge outfall (SDO).
A measurable storm event is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office. See Definitions.
The permittee shall complete the analytical samplings in accordance with the schedule specified in
Table 2, unless adverse weather conditions prevent sample collection (see Adverse Weather in
Definitions). A minimum of 60 days must separate Period 1 and Period 2 sample dates, unless
monthly monitoring has been instituted as part of other requirements of this permit. Inability to
sample because of adverse weather conditions must be documented in the SPPP and recorded on
the DMR. The permittee must report the results from each sample taken within the monitoring
period (see Part 111, Section E). Sampling is not required outside of the facility's normal operating
hours.

1 Maintain semi-annual analytical monitoring throughout the permit renewal process (unless
other provisions of this permit prompt monthly sampling).
If no discharge occurs during the sampling period, the permittee must submit a monitoring report indicating
"No Flow" or "No Discharge" within 30 days of the end of the sampling period. Failure to monitor semi-
annually per permit terms may result in the Division requiring monthly monitoring for all
parameters for a specified time period. "No discharge" from an outfall or inability to collect a
sample because of adverse weather conditions during a monitoring period does not constitute
failure to monitor, as long as it is properly reported.
The permittee shall compare monitoring results to the benchmark values in Table 3. The benchmark
values in Table 3 are not permit limits but should be used as guidelines for the permittee's Stormwater
Pollution Prevention Plan (SPPP). 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. See below the descriptions of Tier One, Tier Two,
and Tier Three response actions below. In the event that DWQ releases the permittee from continued
monthly monitoring under Tier Three, DWQ's release letter remains in effect through the subsequent
reissuance of this permit, unless the release letter provides for other conditions or duration.

Permit No. NCG080000
Tier One
I If: The first valid sampling results are above a benchmark value, or outside of the benchmark range, for any I
parameter at anv outfall;
Then: The permittee shall:
I. Conduct a stormwater management inspection of the facility within two weeks of receiving sampling
results.
2. Identify and evaluate possible causes of the benchmark value exceedance.
3. Identify potential and select the specific: source controls, operational controls, or physical
improvements to reduce concentrations of the parameters of concern, and/or to bring concentrations
within the benchmark range.
4. Implement the selected 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
exceedence, the inspection date, the personnel conducting the inspection, the selected actions, and the
date the selected actions were implemented.
Tier Two
If: During the term of this permit, the first valid sampling results from two consecutive monitoring periods are
above the benchmark values, or outside of the benchmark range, for any specific parameter at a specific
discharee outfal
Then: The permittee shall:
1. Repeat all the required actions outlined above in Tier One.
2. Immediately institute monthly monitoring for all parameters. The permittee shall conduct monthly
monitoring at every outfall where a sampling result exceeded the benchmark value for two consecutive
samples. Monthly (analytical and qualitative) monitoring shall continue until three consecutive sample
results are below the benchmark values or within benchmark range.
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. Benchmark exceedances for a different parameter separately trigger a tiered response.
S. Maintain a record of the Tier Two response in the SPPP,
Tier Three
If: During the term of this permit, if the valid sampling results required for the permit monitoring periods

Section D: Stormwater Discharges: Qualitative Monitoring Requirements
The purpose of qualitative monitoring is to evaluate the effectiveness of the Stormwater Pollution
Prevention Plan (SPPP) and assess new sources of stormwater pollution. Qualitative monitoring of
stormwater 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 requires a visual inspection of each
stormwater outfall regardless of representative outfall status and shall be performed as specified in
Table S, during the analytical monitoring event. Inability to sample because of adverse weather
conditions most be documented in the SPPP and recorded on the DMR (see Adverse Weather in
Definitions). Only SDOs discharging stormwater associated with industrial activity must be
monitored (See Definitions). Qualitative monitoring is not required outside of the facility's normal
operating hours.

Qualitative Monitoring Response
Qualitative monitoring is for the purposes of evaluating SPPP effectiveness, assessing new sources
of stormwater pollution, and prompting the permittee's response to pollution. If the permittee
repeatedly fails to respond effectively to correct problems identified by qualitative monitoring, or if
the discharge causes or contributes to a water quality standard violation, DWQ may but is not
limited to:
• require that the permittee revise, increase, or decrease monitoring frequency for some or
all parameters (analytical or qualitative);
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures;
