PART iI MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The Permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. This Plan shall be considered public information in accordance. with Part III, Standard
Conditions, Section E, Paragraph 3 of this individual permit. The Plan shallinclude, at a
minimum, the following items:
I . Site Plan. The site plan shall provide a description of the physical facility and the
potential pollutant sources which may be expected to contribute to contamination of
stormwater discharges. The site plan shall contain the following:
(a) A general location map (USGS quadrangle map or appropriately drafted
equivalent map), showing the facility's location in relation to transportation routes
and surface waters, the name of the receiving water(s) to which the stormwater
outfall(s) discharges, or if the discharge is to a municipal separate storm sewer
system, the name of the municipality and the ultimate receiving waters, and
accurate latitude and longitude of the point(s) of discharge. The general location
map (or alternatively the site map) shall identify whether each receiving water is
impaired (on the state's 303(d) list of impaired waters) or is located in a
watershed for which a TMDL has been established, and what the parameter(s)
of concern are. —
(b) A narrative description of storage practices, loading and unloadi'rig activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices. A narrative description of the potential pollutants which
could be expected to be present in the stormwater discharge from each outfall.
(c) A site map drawn to scale (including a distance legend) showing: the site property
boundary, the stormwater discharge outfalls, all on -site and adjacent surface
waters and wetlands, industrial activity areas (including storage of materials,
disposal areas, process areas, loading and unloading areas, and haul roads), site
topography, all drainage features and structures, drainage areas for each outfall,
direction of flow in each drainage area, industrial activities occurring in each
drainage area, buildings, existing BMPs, and impervious surfaces. The site map
must indicate the percentage of each drainage area that is impervious.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the three (3) previous years and any corrective actions taken to mitigate
spill impacts.
(e) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The certification statement will be signed in
accordance with the requirements found in Part III, Standard Conditions, Section

• Permit No. NCS000338
B, Paragraph 5. The pennittee,shall, re -certify annually that the stormwater
outfalls have been evaluated for the presence of non-stonmwater discharges.
2. Stormwater Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and,
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of rip.aterials and processes to stormwater. Wherever practical, the permittee shall
prevent exposure of all storage areas, material Handling operations, and
manufacturing or fueling operations. In areas where elimination of exposure is
not practical, the stonmwater management plan 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; storage in any amount of Section
313 of Title III of the Superfund Amendments and Reauthorization Act (SARA)
water priority chemicals; and.storage,in any amount of hazardous substances, in
order to prevent leaks and spills from contaminating stormwater runoff. A table
or summary of all such tanks and stored materials and their associated secondary
containment areas shall be maintained. If the secondary containment devices are
connected to stormwater conveyance systems, the connection shall be controlled
by manually activated valves. or other similar devices (which shall be secured
closed with a locking mechanism), and any stormwater that accumulates in the
containment area shall be at a minimum visually observed for color, foam, outfall
staining, visible'sheens and dry weather flow, prior to release of the accumulated
stormwater. Accumulated stormwater shall be.released if found to be
uncontaminated by any material. Records documenting the individual making the
observation, the description of the accumulated stormwater, and the date and time
of the release shall be kept for a period of five years.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMP) shall be provided. The installation and implementation of BMPs
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and data collected
through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMP Summary shall be reviewed and updated annually.
3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or the team) responsible for implementing the
SPRP shall be identified in a written list incorporated into the SPRP and signed and dated
by each individual acknowledging their responsibilities for the plan. A responsible
Part II Page 2 of 10

• Permit No. NCS000338
person shall be on -site at all times during facility operations that have the potential to
contaminate stonmwater runoff through spills or exposure of materials associated with the
facility operations, The SPRP must be site stonmwater 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. The program shall list
all stormwater control systems, stonnwater 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.
Inspection of material handling areas and regular cleaning schedules of these areas shall
be incorporated into the program. Timely compliance with the established schedules for
inspections, maintenance, and housekeeping shall be recorded in writing and maintained
in the SPPP.
S. Employee Training. Training programs shall be developed and training provided at a
minimum on an annual basis for facility personnel with responsibilities for: spill response
and cleanup, preventative maintenance activities, and for any of the facility's operations
that have the potential to contaminate stormwater runoff. Facility personnel (or team)
responsible for implementing the training shall be identified, and their annual training
shall be documented by the signature of each employee trained.
6. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be documented
and position assignments provided.
7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants to surface waters. All aspects of the
Stormwater Pollution Prevention Plan shall be reviewed and updated on an annual
basis. The annual update shall include an updated list of significant spills or leaks of
pollutants for the previous three years, or the notation that no spills have occurred. The
annual update shall include written re -certification that the stormwater outfalls have been
evaluated for the presence of non-stonnwater discharges. Each annual update shall
include a documented re-evaluation of the effectiveness of the BMPs listed in the BMP
Summary of the Stormwater Management Plan.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall
Part 11 Page 3 of 10

i
iPermit No. NCS000338
submit a time schedule to the Director for modifying the Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part II1, Standard Conditions, Section B, Paragraph 5) to the Director that the changes
have been made.
S. Facility Inspections. Inspections of the facility and all stortnwater 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 of least 60 days separating inspection
dates. (unless performed more frequently than semi-annually). These facility inspections
are different from, and in addition to, the stormwater discharge characteristic monitoring
required in Part II B and C of this pen -nit. `
9. Implementation. The permittee shall implement the Plan. Implementation of the Plan
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

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall. be performed as specified in Table 1. All
analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of ten analytical samplings being conducted over the term of
the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 0.1 inches of rainfall. The time
between this storm event and the previous storm event measuring greater than 0.1 inches must be at least
72 hours. A single storm event may have a period of no precipitation of up to 10 hours. For example, if
it rains but stops before producing any collectable discharge, a sample may be collected if the next rain
producing a discharge begins within 10 hours. '

Permit No. NCS000338
This site discharges to impaired waters experiencing problems with,impaired biological integrity.
If a Total Maximum Daily Load (TMDL) is approved for this segment of Hominy Swamp, the
permittee may be required to monitor for the pollutant(s) of concern in the future and submit
results to the Division of Water Quality. The Division will consider the monitoring results in
determining whether additional BMPs are needed to control the pollutant(s) of concern to the
maximum extent practicable.
If additional BMPs are needed to achieve the required level of control, the permittee will be
required to (1) develop a strategy for implementing appropriate BMPs, and (2) submit a timetable
for incorporation of those'BMPs. into the permitted Stormwater Pollution Prevention Plan.
SECTION C: QUALITATIVE MONITORING REQUIREMENTS
Qualitative monitoring'requires a visual inspection of each stormwater outfall regardless of
representative outfall status and shall be performed as specified in Table 4, during the analytical
monitoring event. [If analytical monitoring is not required, the permittee still must conduct semi-
annual qualitative monitoring.] Qualitative monitoring is for the purpose of evaluating the
effectiveness of the Stormwater Pollution Prevention Plan (SPPP) and assessing new sources of
stormwater pollution.
In the event an atypical condition is noted at a stormwater discharge outfall, 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.

the permittee has submitted the appropriate paperwork for a renewal permit before the submittal deadline, the
permittee will be considered for a renewal application. The applicant must continue semi-annual monitoring until
the renewed permit is issued. See Table 2'for schedule of monitoring periods through the end of this permitting
cycle.
2 If the stormwater runoff is controlled by a stormwater detention pond a grab sample of the discharge from the
pond shalt be collected within the first 30 minutes of discharge from the pond.
3 Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) that discharges
stormwater runoff from area(s) where vehicle maintenance activities occur.
4 For each sampled representative storm event the total precipitation must be recorded. An on -site or local rain
gauge reading must be recorded.
Monitoring results shall be compared to the benchmark values in Table 6. The benchmark
values in Table 6 are not pen -nit limits but should be used as guidelines for the permittee's
Stormwater Pollution Prevention Plan (SPPP). Exceedences of benchmark values require the
pennittee to increase monitoring, increase management actions, increase record keeping, and/or
install stormwater Best Management Practices (BMPs), as provided in Part I1 Section B.
