Jennifer,
All of the quoted sections are "correct" as to what I observed during the NPDES Wastewater
Discharge Permit Inspection. I had planned to do a stormwater inspection of the facility and
realized the facility did not have the required stormwater permit. I notified them of the
requirement and requested they file for the permit. They should be covered under the NCG11
and I have no concerns with the issuance of this permit.
Please let me know if I can be of further assistance.
Sincerely,
Autumn Hoban

Hi Autumn,
We've received an NOI from The Town of Hillsborough for a stormwater permit for their
existing WWTP (Orange County) for coverage of their gemstone mine under NCG11
(Treatment Works). They already have a waste water discharge permit NPDES NC0026433.
The site discharges stormwater (and WW) into the Eno River (index number 27-2-3) (class
C, NSW). The NOI is attached.
Does the Raleigh Regional Office have any concerns about issuing this facility a COC for
this general permit, and are there any potential impacts to wetlands?
The questions/notes I had about this site were:
a. Did you see anything unusual about any of these things on your site visit in Jtme?
a. Chemicals: It says "chemicals and/or materials maintained in drums that are
stored outside are, are kept covered to prevent stormwater from contacting
the materials."
b.- Grit: "Pretreatment removes coarse screenings and grit removal. Screenings

Town of Hillsborough Waste Water Treatment Facility
Stormwater Pollution Prevention Plan September 2007
1. Site Plan and General Information
The Town of Hillsborough (Town) operates a Waste Water Treatment Plant (WWTP) at the
following address:
Town of Hillsborough
Waste Water Treatment Plant
355 Elizabeth Brady Road
Hillsborough, North Carolina 27278
The facility has been approved to discharge effluent into the Eno River under a National
Pollutant Discharge Elimination System (NPDES) permit from the North Carolina Division of
Water Quality (NCDWQ), permit number NC0026433.
Additionally, this facility is required to have NPDES permit coverage to discharge stormwater
from the site to the receiving water. Discharge of stormwater from this facility is covered
under General Permit No. NCG110000 issued by NCDWQ.
As part of the permit requirements this facility must have a Stormwater Pollution Prevention
Plan (Plan). This plan is designed to reduce and/or eliminate the discharge of pollutant -
laden stormwater from the facility into the receiving water.
The Town will amend this plan whenever there is a change in the design, construction,
operation, or maintenance of the facility, which may potentially allow the discharge of
pollutants to surface waters. This plan will be reviewed and updated on an annual basis.
A. Location and Site Description
The Town's WWTP is located on a 26.3 acre tract in Hillsborough, Orange County. A
Location map is included as Attachment 1. Approximately 7 acres of the site was cleared
to construct the facility. Of these 7 acres, about 3 acres contains facility components and
the remainder (about 4 acres) is maintained as lawn. The remaining 19.3 acres is
forested.
The Town's WWTP is located within the Neuse River Basin which has been designated
as a Nutrient Sensitive Watershed. The Eno River is the receiving water, which borders
the facility property. This segment of the Eno River is designated as a Class C by
NCDWQ (Index number 27-2-(7)). A forested buffer is maintained between the actual
facility and the Eno River. The buffer width varies from approximately 30 to more than
300 feet wide.
B. Site Map/Plan
A more detailed site map/plan is provided as Attachment 2. The major components of
the facility, drainage patterns, receiving water, and stormwater outfalls are noted.
C. Site Description/Storage Practices
The Town's WWTP is permitted to process up to three (3) million gallons of wastewater
per day using a two stage secondary treatment process. A description of the process
flow and diagram are included in Attachment 3.
1

Town of Hillsborough
Stormwater Pollution Prevention Plan
Waste Water Treatment Facility
Seotember 2007
While stormwater can come into contact with some of the facility components such as
the aerators and clarifiers, precipitation falling on these components simply travels
through the wastewater treatment process. Excessive rainfall could cause an overflow.
This is monitored during operation and handled in accordance with the facility's NPDES
wastewater discharge permit.
Generally the WWTP uses biological processes to treat the wastewater. However, as
noted on the schematic there are some chemicals needed. These chemicals are stored
and handled so that they do not come into contact with stormwater. Enclosed- chemical
Aunloading stations are equipped with a quick connect, hard piped nozzle. Chemicals
and/or materials maintained in drums that are stored outside, are kept covered to
prevent stormwater from contacting the materials.
Pretreatment removes coarse screenings and grit removal. Screenings are placed in
plastic garbage receptacles, which are sent to a landfill for disposal. This step in the
process does have some potential for stormwater to come into contact with the
screenings, prior to disposal. Handling of the screenings will be evaluated as part of this
plan to determine if there is a method to eliminate the potential contact. Other garbage
and waste materials are stored outside in covered dumpsters for collection and disposal
at a local landfill. r
The WWTP produces biosol ids as part of the treatment process. Biosolids are removed
from the facility and applied to pe mitted land application areas. The process includes a
rotary drum thickener, aerobic digesters and lime pasteurization. Dry lime is stored in a
silo .and -mixed -with -the -sludge. Some components of th^ � e biosolids-management
process can come in contact-with-stormwater-but-the system has enough capacity to
contain rain failing o to hefacility. Once the biosolids are treated meeting the Class "B"
certification, they are transferred tp a storage tank. From there they are loaded and
hauled off for land application.
There are no vehicle maintenance facilities on -site, although a fueling station with above
ground storage is present. The above ground tank has appropriate secondary
containment.
The WWTP contains minimal stormwater facilities that drain the developed portion of the
site. These include curb and drop inlets, connected piping and flared end stormwater
outfalls. There are five (5) stormwater outfalls that drain through forested buffers before
entering the Eno River. Locations of the stormwater facilities are shown on the Site Map
in Attachment 2. While there is outside material handling and storage areas located
throughout the facility, these areas do not discharge directly to the stormwater drainage
system.
D. Spill List
There have been no spills or leaks of pollutants that have occurred at the facility within
the last three (3) years.

E. Stormwater Outfall Certification
I certify that under my direction or supervision the stormwater outfalls noted on the site
map/plan for this facility have been inspected for the presence of non-stormwater
discharges. Based on that evaluation, non-stormwater discharges were not present.

Town of Hillsborough Waste Water Treatment Facility
Stormwater Pollution Prevention Plan September 2007
2. Stormwater Management Plan
A. Feasibility Study
The Town of Hillsborough WWTP has already evaluated and implemented measures to
reduce and/or eliminate polluted stormwater to the extent practicable. Therefore a
specific feasibility study is not included. The measures implemented include secondary
containment and best management practices (BMP) as described in the following
sections.
B. Secondary Containment Schedule
Currently, above ground storage tanks within the facility include secondary containment.
Accumulated stormwater is released from secondary containment only when it is
considered clean.
C. BMP Summary
Both non-structural and structural stormwater BMPs have been employed at the
Hillsborough WWTP to reduce and/or eliminate stormwater runoff pollution from the site.
The site layout takes advantage of non-structural means to protect the receiving water.
As stated earlier, much of the 23-acre site remains as a forested buffer along the Eno.
Managed lawn areas serve as grass filters and encourage infiltration of stormwater.
Structural BMPs include secondary containment around above ground storage tanks
and enclosed material/chemical storage. Materials that are stored outside are kept in
covered drums. In addition, the components of the facility are operated so that
stormwater falling in them are simply processed with the wastewater. Should a facility
component fail, procedures are in place for a pump around. Details on operating
procedures are maintained onsite.
Finally, the WWTP employs good housekeeping procedures to reduce stormwater
pollution. For instance, spills are cleaned up immediately. While these procedures have
not been focused on stormwater in the past, they will be from this point forward. The
good housekeeping program is detailed in Section 4 of this document.
3. Spill Response Plan
Spill prevention is practiced at each step in the facility operation as described in this
document. The facility does have a Spill Response Plan in case of a spill. A copy of the
Spill Response Plan is included as Attachment 4.
4. Preventative Maintenance and Good Housekeeping Program
A. Preventative Maintenance Program
The Town's WWTP staff already conducts a preventative maintenance program. This
includes regular inspection and testing of plant equipment and operational systems. All
facility components are included in a Microsoft Access Database. This database is used
to schedule inspections and maintenance. Depending on the component, inspections
4

Town of Hillsborough
Stormwater Pollution Prevention Plan
Waste Water Treatment Facility
September 2007
are completed annually, quarterly, and daily, up to six times each day. The preventative
maintenance program is required to comply with the facility's NPDES wastewater permit.
Therefore, specific details are not listed here but are maintained on -site.
Stormwater outfalls have not been included as regular inspection items under the
facility's preventative maintenance program. However, routine inspections of inlets and
outfalls will now be conducted as part of the facility operation and good housekeeping
plan. Facility personnel will be trained to inspect the stormwater infrastructure at the
facility under the Good Housekeeping Program detailed below.
The stormwater outfalls and other stormwater infrastructure at the facility have been
inspected initially as required by the non-stormwater discharge certification, and have
had an initial inspection under the Good Housekeeping Program. The facility will be
inspected annually under this program to ensure stormwater infrastructure is working
properly. Inspection reports are included in Attachment 5.
B. Good Housekeeping Program
The Town of Hillsborough has been designated as an NPDES Phase 11 Stormwater
community. As such, the Town is required to implement a Good Housekeeping Program
on each of their facilities.
In the fall of 2007, the Town will be implementing initial inspections of their facilities to
determine what practices or other BMPs need implemented, if necessary. After the
initial inspections, facilities will be re -inspected annually to determine if Good
Housekeeping practices are being implemented to reduce or eliminate stormwater
pollution. The inspection reports will be incorporated as part of this plan, including any
action items required. Status of action items will be updated and also included in
Attachment 5. The initial Good Housekeeping inspection was conducted as part of this
Plan and the results are included in Attachment 5.
5. Employee Training
As part of the Town's Good Housekeeping program under their NPDES Phase II stormwater
permit, employee training is required. Employee training materials have been developed
and training is being implemented beginning in the fall of 2007. Personnel at the Town's
WWTP will be the first to receive this training.
The training program includes two primary components. The first provides information why
stormwater pollution prevention is important. The water cycle is reviewed, and specific
impacts stormwater pollution can have on the aquatic environment are discussed.
The second component includes a video describing Good Housekeeping practices
specifically for municipal operations. The video discusses why these practices are important
and how they can prevent stormwater pollution.
Both components are supplemented with handouts and includes a quiz. All WWTP will
receive the initial training, as will new employees. Subsequently, training will be conducted
on an annual basis based on the annual stormwater inspection results.

Town of Hillsborough
Stormwater Pollution Prevention Plan
Waste Water Treatment Facility
September 2007
The Good Housekeeping training for the WWTP will be in addition to training required under
other regulations, the SPPC plan, and preventative maintenance activities required for the
plant. A training schedule and list of employees trained will be maintained as part of this
Plan as Attachment 6.
6. Responsible Party

R.3. PROCESS FLOW DIAGRAM
Town of Hillsborough WWTP PFD Description
Influent Pumps
The pump station has three centrifugal pumps rated at 2,000 gpm each. The station has a
-- firm capacity of 5.76 mgd.
Manual Bar Screen and Grit Chamber
Grit is removed using an aerated grit chamber. The grit chamber has an estimated capacity
of 8.44 mgd based on maintaining a 3 minute detention time at peak hourly flow.
The manual bar screen is located physically within the grit chamber, screening de -gritted
effluent.
Two Stage Secondary Treatment
The two stage secondary treatment system is adequately sized to remove BOD and nitrify at
3 mgd but are not configured to biologically remove nitrogen and/or phosphorus. The
stage 1 aeration basins are designed to remove BOD and TSS. Currently, only two of the
four cells are used. The cells in service operate with four mechanical surface aerators.
All four cells of the stage 2 aeration basins are utilized and are designed to nitrify and
remove phosphorus through chemical precipitation. Each cell is equipped with a
mechanical surface aerator.
The current configuration is intended to provide BOD and TSS removal in primary aeration
basin with nitrification occurring in the secondary aeration basinAs stated previously,
phosphorus is removed by chemical precipitation with alum
Final Clarifiers
The Plant has two final clarifiers associated with the stage 1 aeration basins and two final
clarifiers associated with the stage 2 aeration basins; both are currently in service. The
clarifiers are equipped with a submerged beach for scum removal and generate Return
Activated Sludge (RAS) through use of a siphon attached to a traveling bridge.
The siphon flow is regulated by manually adjusting the elevation of a weir attached to the
traveling bridge.
The effluent troughs consist of V-Notch weirs. Visual observations included floating sludge
and an excessive amount of sludge carryover into the effluent (the sludge carryover is Iess
noticeable in the stage 2 final clarifiers). The presence of floating sludge indicates that some
denitrification is occurring within the clarifiers.
Sludge Pumping Stations
The Plant has two sludge pumping stations, one for each stage of secondary treatment.
Each station has two RAS pumps and one Waste Activated Sludge (WAS) pump.

TOWN OF HILLSSBOROUGH WWTP
NPDES FORM 2A
B.3. PROCESS FLOW DIAGRAM
Filtration
The tertiary treatment system consists of three pressure multi -media filters. The filters are
rated for 700 gpm each for a total capacity of 2,100 gpm or 3.02 mgd. Four (4) 1,000 gpm
pumps are provided to feed the filters.
C h lori n atio n/Dec h lori n atio n
The filter effluent is currently disinfected using chlorine gas in solution Currently, sulfur
dioxide is used for dechlorination. The chlorination system utilizes one -ton cylinders while
the dechlorination system used 150-lbs cylinders.
Biosolids Management
The biosolids management system consists of a rotary drum thickener, aerobic digesters, a
lime pasteurization reactor, and biosolids storage.
Rotary Drum Thickener
The rotary drum thickener is is rated for 150 gpm. The thickener uses a polymer feed
system to condition the sludge prior to entering the unit. Thickened sludge is discharged to
a wet well which is mixed with a Flygt 4630 compact mixer to keep the sludge from settling.
Two Seepex Progressive Capacity pumps equipped with 7.5 hp motors and rated from 125
gpm convey the thickened sludge from the wet well to the aerobic digesters.
Aerobic Digesters
Thickened waste sludge from the rotary drum thickener is stabilized in two 72,000 gallon
aerobic digesters. Each digester is 35-feet in diameter with a 10-foot side water depth and is
equipped with a 15 hp aerator. Two 150 gpm progressive cavity pumps transfer digested
sludge to the Iime pasteurization reactor.
Lime Pasteurization
Stabilized solids from the aerobic digesters achieve Class B certification for pathogen and
vector attraction reduction via lime pasteurization. Digested sludge and dry lime are mixed
in a 12,000 gallon RDP time pasteurization reactor. Dry lime is stored in a silo with 60 cubic
feet of capacity.
Biosolids Storage
Lime pasteurized solids meeting the Class B' certification is transferred to a 284,000 gallon
storage tank. The tank is 56-feet in diameter with a 15-foot side water depth. Two 20-hp
Environmental Equipment Engineer, Inc submersible mixers keep the solids from settling
prior to hauling and land application.

PART I INTRODUCTION
SECTION A: GENERAL PERMIT COVERAGE
All persons desiring to be covered by this General Permit must register with the Division of
Water Quality by the filing of a Notice of Intent (NOI) and applicable fees. The NO[ 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.
=I
Facilities submitting NON for coverage under this permit, prior to establishment or approval of a
Total Maximum Daily Load (TMDL) for a priority pollutant(s) for stormwater discharges (i.e.
wet weather flows), may be covered under this permit during its term. For such facilities
continued coverage under the reissuance of this permit is subject to the facility demonstrating
that it does not have a reasonable potential to violate applicable water quality standards for such
pollutants due to the stormwater discharge(s). For facilities that do have a reasonable potential
for violation of applicable water quality standards due to the stormwater discharge(s) the facility
shall apply for an individual permit 180 days prior to the expiration of this general permit. Once
the individual permit is issued and becomes effective the facility will no longer have coverage
under the general permit. A list of approved TMDLs for the state of North Carolina can be found
at http://h2o.enr.state.ne.us/tmdl/General_TMDLs.htm.
During the period beginning on the effective date of the permit and lasting until expiration, the
Permittec is authorized to discharge stormwater associated with industrial activity. Such
discharges shall be controlled, limited and monitored as specified in this permit.
SECTION B: PERMITTED ACTIVITIES
Until this permit expires or is modified or revoked, the permittee is authorized to discharge
stormwater to the surface waters of North Carolina or separate storm sewer system which has
been adequately treated and managed in accordance with the terms and conditions of this General
Permit. All discharges shall be in accordance with the conditions of this permit.
Any other point source discharge to surface waters of the state is prohibited unless it is an
allowable non-stormwater discharge or is covered by another permit, authorization or approval.
The discharges allowed by this General Permit shall not cause or contribute to violations of
Water Quality Standards.
Part I Page 1 of 2

Permit No. NCG 110000
This permit does not relieve the permittee from responsibility for compliance with any other
applicable federal, state, or local law, rule, standard, ordinance, order, judgment, or decree.
SECTION C: PERMIT RENEWAL
Dischargers covered by general permits need not submit new Notices of Intent or renewal
requests unless so directed by the Division. If the Division chooses not to renew a general
permit, all facilities covered under that general permit shall be notified to submit applications for
individual permits or notified to take other appropriate actions at the discretion of the Director.

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 h, Paragraph 3 of this general permit. The Plan shall include, at a minimum,
the following items:
1. Site Plan. The site plan shall provide a description of the physical facility and the
potential pollutant sources which may be expected to contribute to contamination of
stormwater discharges. The site plan shall contain the following:
(a) A general location map (USGS quadrangle map or appropriately drafted
equivalent map), showing the facility's location in relation to transportation
routes and surface waters, the name of the receiving water(s) to which the
stormwater outfall(s) discharges, or if the discharge is to a municipal separate
storm sewer system, the name of the municipality and the ultimate receiving
waters; and accurate latitude and longitude of the point(s) of discharge.
(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.
(c) A site map drawn to scale with the distance legend indicating location of
industrial activities (including storage of materials, disposal areas, process areas
and loading and unloading areas), drainage structures, drainage areas for each
outfalI and activities occurring in the drainage area, building locations, existing
BMPs and impervious surfaces, and the percentage of each drainage area that is
impervious. For each outfall, a narrative description of the potential pollutants
which could be expected to be present in the stormwater discharge.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the 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
B, Paragraph 5.
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:
Part 11 Page 1 of 5

Permit No. NCG 110000
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. Wherever practical, the permittee shall
prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations. In areas where elimination of exposure is
not practical, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
(b) Secondary Containment Schedule. A schedule to provide secondary containment
for bulk storage of liquid materials, storage of Section 313 of Title III of the
Superfund Amendments and Reauthorization Act (SARA) water priority
chemicals, or storage of hazardous substances to prevent leaks and spills from
contaminating stormwater runoff. If the secondary containment devices are
connected directly to stormwater conveyance systems, the connection shall be
controlled by manually activated valves or other similar devices [which shall be
secured 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 the material stored within the containment area. 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 narrative description shall be provided of Best Management
Practices (BMPs) to be considered such as, but not limited to, oil and grease
separation, debris control, vegetative filter strips, infiltration and stormwater
detention or retention, where necessary. The need for structural BMPs shall be
based on the assessment of potential of sources to contribute significant quantities
of pollutants to stormwater discharges and data collected through monitoring of
stormwater discharges.
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 team) responsible for implementing the
SPRP shall be identified. 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, a SPCC plan 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 program shall be developed. The program shall document schedules of
inspections and maintenance activities of stormwater control systems, plant equipment
and systems. Inspection of material handling areas and regular cleaning schedules of
these areas shall be incorporated into the program.
Employee Training. Training schedules shall be developed and training provided at a
minimum on an annual basis on proper spill response and cleanup procedures and
Part U Page 2 of 5

Permit No. NCG110000
preventative maintenance activities for all personnel involved in 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.
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.
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. The Stormwater Pollution
Prevention Plan shall be reviewed and updated on an annual basis.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall
submit a time schedule to the Director for modifying the Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part III, Standard Conditions, Section B, Paragraph 5) to the Director that the changes
have been made.
8. Facility Inspection Program. Facilities are required to inspect all stormwater systems on
at least a semiannual schedule, once in the fall (September -November) and once during
the spring (April - June). 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.
Stormwater discharge characteristic monitoring as required in Part II of this permit shall
be performed in addition to facility inspections.
9. Implementation. The permittee shall document all monitoring, measurements,
inspections and maintenance activities and training provided to employees, including the
log of the sampling data and of activities 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 years and made available to the Director or his
authorized representative immediately upon request.
SECTION B: QUALITATIVE MONITORING REQUIREMENTS
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status and shall be performed as specified below in Table 1. Qualitative
monitoring is for the purpose of evaluating the effectiveness of the Stormwater Pollution
Prevention Plan (SPPP) and assessing new sources of stormwater pollution. No analytical tests
are required. Qualitative monitoring of stormwater outfalls does not need to be performed during
a representative storm event.
Part 11 Page 3 of 5

Permit No. NCG 110000
Qualitative monitoring will be performed twice per year, once in the spring (April - June) and
once in the fall (September - November).

regardless of representative outfall status.
SECTION C: ON -SITE VEHICLE MAINTENANCE MONITORING REQUIREMENTS
Facilities which have any vehicle maintenance activity occurring on -site which uses more than
55 gallons of new motor oil per month when averaged over the calendar year shall perform
analytical monitoring as specified in Table 2. This monitoring shall be performed at all outfalls
which discharge stormwater runoff from the vehicle maintenance areas.
For each parameter, the arithmetic mean of all analytical sampling results collected during the
coverage of the permit shall be calculated for each individual outfall. The computed arithmetic
mean is then compared to the cut-off concentrations listed in Table 3. If the arithmetic mean is
less than the specified cut-off concentration for a parameter other than pH or within the specified
range for pH only, then the facility is not required to continue annual analytical monitoring for
that parameter (at that outfall) during the remaining coverage of the permit unless a significant
change in facility operations or configuration occurs. If a cut-off concentration results in
discontinued analytical monitoring at an individual discharge outfall, the permittee is required to
maintain facility operations that ensure the continuation of stormwater runoff quality.
The nermittee must perform analvtical samt)liniz during the first vear that the facility becomes
subiect to this Section C and last vear of uermit coverage reeardless of cut-off concentration
conditions. Analytical results from sampling during the final year of permit coverage must be
submitted with the permit renewal application. All analytical monitoring shall be performed
during a representative storm event.
