FACILITY -SPECIFIC INFORMATION
Total Area of Facility Site:
Total Area of Building Structures:
Percent of Site that is Impervious:
Number of Storm Water Outfalls:
Approximately 55 (acres)
Approximately 186,140 (square feet)
Approximately 43 (�)
3
General Description of Site Topography: Relatively flat with moderate sloping away from
the offices, buildings and storage areas towards the southeast and south- borders of the
property. The majority of runoff from exposure is along the southern and southeastern
sides of the property, including the larger portions of the outside storage area, and flows
toward storm water outfalls 001, 002 and 003 which convey runoff off site and to an
unnamed tributary to Camel Branch. Outfall 003 is the discharge of overflow from a small
earthen retention basin. All other areas of exposed industrial activities on the
property that do not exit from either of the three stormwater outfalls exit the property as
sheet runoff and are not point source releases.
Closest Surface Body of Water: Unnamed tributary to Camel Creek
General Description of Surrounding Properties: The facility is located in a rural area
predominated by agriculture, single family residences and scattered industrial
development. The site has been cleared and graded relatively flat.

Secondary Containment Requirements and Records:
Harmony, NC has existing secondary containment for the storage of liquids (oil, gas, etc,)
located at the fuel/oil dispensing station. This containment is a rectangular concrete pad
with walls. The walls have been repaired in the past but additional cracks were found,
Outdoor containers of waste oil and petroleum based liquids should be placed in areas
providing secondary containment. Any permanent storage of such fluids in locations outside the
existing secondary containment area should be provided their own secondary containment.
The site evaluation of G & G did not reveal any Section 313 of Title III listed water priority
chemicals or other hazardous materials in amounts or locations that would threaten to be
released into or contaminate stormwater runoff.
Evaluation of Feasible Alternatives to Current Practices:
The majority of industrial related activities already occur indoors and thus, there would be
no alternatives to further minimize the potential for exposure for these actions
As discussed in the Summary of SWP3 requirements (beginning page 2), it has been
suggested that the company may avoid conducting semi annual sampling of the outfalls if
they endeavor to eliminate the current practice of leaving wood dust, bark, chips and
similar materials exposed outdoors for greater than seven days. The company has been
advised that they should consider if it is practical to eliminate this practice by either
changing current procedures to eliminate this outdoor exposure or by utilizing other areas
of the site where there is covered impermeable surfaces that could serve for this purpose.
This is a decision that must ultimately be made by the company personnel most familiar
with the practical needs of day to day operations.
Also discussed in the SWP3 is that there should be a general improvement in efforts to
minimize the accumulation of unused equipment, parts, scrap, etc. that are currently
exposed to stormwater. This is basically improved housekeeping which should be
technically and economically feasible.

The listed practices should be reviewed periodically as both a
refresher and to evaluate if any changes or improvement are
appropriate.

Pa ge 28
BEST MANAGEMENT PRACTICES
Good Housekeeping
The quantity of pallets, equipment, and other materials stored outside should be minimized, although some
outside storage is necessary due to the nature of business and limitations on available indoor space.Materials
currently stored outside should, where practicable, be moved under roof or to a covered area, stored on
pallets or racks and covered with a secured leak -proof tarpaulin if excessively dirty or oily,or removed from
the site and disposed of if it is not intended to be used.
2. All drums and containers of oils, chemicals and all hazardous materials containers should be properly secured
and labeled.
No excessively oily materials should be placed in trash dumpsters,
Toxic and hazardous materials should be stored inside, if safety provisions allow,. or in a covered area.
The facility should be kept clean by regularly picking up all trash and litter, and by routine sweeping of
exposed impervious areas.
6. Proper fertilization, herbicide and pest control procedures are to be used to prevent overuse of these
materials.
Travelled paved areas should be swept on a regular basis during summex months. Paved areas are not to be
hosed down, except that a small amount of water may be sprayed onto pavement for dust control (but not
enough to generate runoft). Oil shall not be applied for dust control.
Roof drainage should be directed away from material storage areas.
9. Notices should be posted as appropriate to discourage the dumping of materials into storm drains.
10, Pollution prevention concepts shall be regularly communicated to employees.
I]. Painting Operation BMPs:
a. A, poct and properly prepare parts or areas for painting,
b. Contain and properly dispose of or reuse sanding wastes.
C. Prevent paint waste from contacting storm water.
d. Properly store paint and solvents under cover.
C. Make sure paint equipment is operating efficiently and does not leak.
f Recycle paint, paint thinner and solvents.

Page 29
Good Housekeeping (continued)
12. Loading and Unloading Materials:
a. Loading dock areas should be swept on a regular basis.
b. Loading docks should be constructed to allow trucks to back up flush to the building. If that is not
practicable, then roofs over the loading docks, or loading dock skirts or seals which enclose the end
of the trailer should be provided.
C. Grade berm or curb area around loading area to prevent storm water run-on contamination.
d. Inspect trucks for leaks.
e. Clean loading area for accident spills immediately.
13. Industrial Waste Management Areas and Outside Manufacturing:
a. Develop guidelines for the elimination or reduction of waste generation, where appropriate.
b. Check waste management areas for leaking containers or tanks.
C. Keep waste management activities indoors, where possible, after insuring all safety concerns such as
fire hazard and ventilation are addressed.
d. Cover waste piles with temporary covering material such as reinforced tarpaulin, polyethylene,
polyeurathane, polypropalene, or hypalon.
14. Outside Storage of Raw Materials, By -Products or Finished Products:
a. Store materials indoors to the extent practicable.
b. Cover work and storage areas with a roof to the extent practical.
C. Cover any dirty or oily material with temporary covering made of polyethylene, polyeurathane,
polypropalene, or hypalon.
d. Prevent storm water run-on by enclosing area or building a berm around area.
e. Store materials, where practicable, off of the ground surface to prevent contact with run-on
stormwater.

Spill Prevention and Response
1. Spill control measure;; m
1'equire repair of any damaged container prior to outdoor transport arid. immediate
clean-up of spilled material to the greatest extent practicable.
2. Any observed leak or spill should be immediately contained and cleaned up. The cause of the problem shoul
be repaired as soon as possible, Drip pans or similar containers shall be placed under any leaking piece of
stationary equipment until the leak is repaired.
3. D cleanup methods using Dry p s g an absorbent material, shall be utilized where appropriate on all significant leaks
and spills. An adequate supply of absorbent materials shall be maintained, and used absorbent material shall
be swept up and properly disposed of.
l. An adequate amount of dry absorbent should be stored near tanks, oil storage facilities, scrap metal holding
areas and other areas prone to spills, and used as needed to contain and clean up spills.
5. Berms and curbing may be constructed to contain areas prone to spills.
6 Proper compatible storage containers should be used for materials stored outside. Any damaged containers
should be repaired or the materials in the damaged containers transferred to a new undamaged container. A11
containers should be clearly labeled.
Drums containing liquids, including oil and lubricants, slhall be stored indoors, in a bermed area; in overpack
containers or spill pallets; or in similar containment devices.
8. Absorbent pads and blankets may be placed in, or around, storm drains to collect sediments and oily
substances in the event of a spill or leak occurence,
9. Filling of propane and other gaseous tanks should not occur during storm events.

Page 32
BEST MANAGEMENT PRACTICES
Sediment and Erosion Prevention
Unpaved yard/operation areas should be periodically regraded to prevent the formation of rut and
gullies. Gravel and stone aggregate placed at the sites should be coarse, with a minimum amount of
fine particles which would be easily flushed by runoff.
2. A good vegetative cover should be maintained in non -operational unpaved areas.
Any obset-ved erosion, scouring or sedimentation should be controLtd using appropriate vegetative,
stabilization, or structural measures.
Rip -rap may be used in swales, ditches or channels to minimize erosion.
Maintain silt fencing or hay bales around catch basins, swales, ditches, etc, in affected during land
disturbing construction activities, to filter solids from stormwater runoff,

This program has been developed to address the annual training for stormwater
pollution control required for all employees. It is recommended that all
employees receiving this training be listed by name and date on a log sheet or it
should be indicated that all employees were trained, and that this sheet be kept
as a part of the Stormwater Pollution Prevention Plan.
This program may be administered either verbally or by distributing a written
copy of this program as a handout. It is recommended that the training include
both.
This program should be repeated at least once per year to all employees and
may coincide with additional meetings (i.e. safety meetings, etc.). This program
has been assembled to function both as an initial training and an annual
refresher.
In the future, if conditions should significantly change, this program should be
appropriately updated or revised.

Stormwater Pollution Control
Employee Training Program
I. Introduction
State and Federal regulations require that companies involved in certain types of
industrial activities with exposure to rainfall, obtain a "Stormwater Discharge
Permit". These permits contain requirements that include the preparation of a
stormwater pollution prevention plan.
This company has obtained a stormwater discharge permit and has developed a
stormwater pollution prevention plan. The stormwater pollution prevention plan is
a tool for implementing practices to minimize the potential for pollutants to be
discharged off site as a result of exposure to rainfall.
II. Purpose of Employee Training Program
An integral part of the stormwater pollution prevention plan is the inclusion of
employee training and interaction. This training program is intended to acquaint
you with the stormwater pollution prevention program as a whole and to
familiarize you with the appropriate specific aspects. This training should help
you to be aware of actions or precautions you can take to assist in minimizing
the potential for pollutant runoff. It is also intended to encourage your comments
and suggestions.
III. Stormwater Pollution Prevention Team
A team has been established for overseeing the implementation of the
stormwater pollution prevention plan. This team may be changed from time to
time but now consists of the following members:
1. Brandon Gregory (Leader)
2. David Coltrane
The team has the lead role in overseeing stormwater management activities but
stormwater management and activities to minimize pollutant runoff is every
employee's responsibility. Questions or suggestions regarding stormwater
management should be directed to the team leader.
- 1 -

Avoiding and controlling the release of pollutants through spills and leaks is a
key component of stormwater management. The stormwater pollution
prevention plan for this company contains best management practices for spit I
prevention and response.
Employees play a vital role in helping to avoid spills and leaks of materials that
might otherwise enter a drain, ditch, etc. that could transport the pollutants off
site. Employees should be mindful that they are involved in many day-to-day
activities that could impact whether spills or leaks occur.
For the most part, employees should use good common sense in avoiding
situations that increase the potential for mishaps occurring. Employees should
be particularly mindful of the following:
1. Avoid placing chemicals and liquid materials in areas adjacent to
drains, ditches or other type conveyances.
2. Store materials in a proper manner to minimize the potential for
punctures or spills.
3. Use only sound containers, suitable for the type of material being
held.
4. Store containers on a firm, level surface. Avoid leaving barrels,
pales, etc. tilted since this increases potential for overturning.
5. Avoid storing chemicals and liquids in heavily trafficked areas.
6. Avoid storing flammable materials in proximity to potential ignition
sources (e.g. flames, welders, sparks, etc.).
7. Do not leave open containers exposed to rainfall.
8. Use care when filling tanks, containers and equipment so as to
avoid overfilling and spillage.
-2-

V. HouseKeqpjng
Good housekeeping practices aid in minimizing the release of pollutants in
stormwater by directly reducing the exposure of materials to runoff conditions
and by lessening the probability of spill or leaks occurring due to unsafe
conditions. Employees are constantly involved in activities that directly affect the
orderliness and cleanliness of the company. Each employee should understand
that it is important that work activities must include conscious effort to keep areas
free of extraneous debris, unused equipment, materials, etc, and generally an
orderly manner.
Employees should give particular attention to the following:
Avoid allowing the accumulation of excess materials especially in
areas exposed to precipitation.
2. Avoid overfilling waste containers (e.g. dumpsters, roll off boxes,
trash cans, etc.). Full containers should be properly disposed and
replaced.
3. Avoid accumulating junk equipment, parts, etc. in areas exposed to
precipitation and/or in a disorderly manner.
4. Place all waste material in proper storage containers.
VI. Materials Management Practices
A significant potential for pollutant discharge is associated with management of
materials used in the manufacturing processes. Where possible, these materials
should be kept in places where there is no exposure to direct precipitation.
Employees should be aware that they share in the responsibility to use good
judgement and make every reasonable effort to minimize the potential for
pollutant runoff as a result of material handling practices.
Employees should be especially attentive to the following:
1. Liquid materials (e.g, solvents, paints, finishes, oils, lubricants, etc,)
should be kept in designated areas indoors, in proper containers and
in an orderly manner.
-3-

2. Wherever possible, any materials that must be stored outside should
be done so in a manner to minimize potential for pollutant runoff.
Certain practices that can help include:
a. Proper stacking to minimize the exposed surface
area.
b. Avoid storing materials immediately adjacent to storm
drains, swales, ditches or other stormwater
conveyances.
C. Minimize, as much as practical, the accumulation of
excess materials in exposed areas.
3. Unusable materials should be properly discarded off site to avoid
the accumulation of unnecessary exposed materials.
4. After use, the unused portion of materials that can eventually be
used should be returned to its appropriate location and kept in a
proper manner.

Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event." However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office.

Permit No. NCG210000
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 Energy, Mineral, and Land Resources (DEMLR) by the filing of a Notice of Intent (NOI) and
applicable fees. The NOI shall be submitted and a certificate of coverage issued prior to any 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 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
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 the Department 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 II, Section A. A list of approved TMDLs for the state of North Carolina can be
found at https:Hdeq.nc.gov/about/divisions/water-resources/planning/modeling-assessment/tmdls/draft-
and-approved-tmdls.
Part I Page 1 of 2

Permit No. NCG210000
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 to a separate storm sewer system,
which has been adequately treated and managed in accordance with the terms and conditions of
this General Permit and the requirements of the permittee's Certificate of Coverage (COC). The
permittee's COC is hereby incorporated by reference into this General Permit. Any violation
of the COC is a violation of this General Permit and subject to enforcement action as provided
in the 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.
Discharge of leachate from accumulations of small -sized woody materials is not considered an
allowable non-stormwater discharge and may be more appropriately covered under General
Permit NCG240000 Compost Facilities. The discharges allowed by this General Permit shall not
cause or contribute to violations of Water Quality Standards. Discharges allowed by this
permit must meet applicable wetland standards as outlined in 15A NCAC 213.0230 and .0231 and
water quality certification requirements as outlined in 15A NCAC 2H .0500.
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.

Permit No. NCG210000
PART II — MONITORING, CONTROLS, AND LIMITATIONS FOR PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The permittee shall develop and implement a Stormwater Pollution Prevention Plan (SPPP). The
SPPP shall be maintained on site unless exempted from this requirement by the Division. The SPPP is
public information in accordance with Part III, Standard Conditions, 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 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.
(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 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 III,
Standard Conditions, Section B, Paragraph 5.
Part II Page 1 of 13

Permit No. NCG210000
2. 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 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 including petroleum products; 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). 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
Plan (SPCC), any portion of the SPCC plan fully compliant with the requirements of this permit
may be used to demonstrate compliance with this permit. The Division may allow exceptions
to secondary containment requirements for mobile refuelers, as with the exemption provided
by amendments to federal SPCC regulations, as long as appropriate spill containment and/or
diversionary structures or equipment is used to prevent discharge to surface waters.
Exceptions do not apply to refuelers or other mobile tankage used primarily as bulk liquid
material storage in a fixed location in place of stationary containers.
(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.
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
Part II Page 2 of 13

Permit No. NCG210000
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.
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 II B and C of
this permit.
6. 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 implementing the
training shall be identified, and their annual training shall be documented by the signature of
each employee trained.
7. 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.
8. 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 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 ofsample analytical data to benchmark values (if applicable)
over the past year, including a discussion about Tiered Response status. The
Part II Page 3 of 13

Permit No. NCG210000
permittee shall use the Division's Annual Summary Data Monitoring Report (DMR)
form, available from the Stormwater Permitting Unit's website (See:
https://deg.nc.gov/about/divisions/energy-mineral-land-resourcesInpdes-
stormwater-gps).
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 II1, Standard Conditions, Section B,
Paragraph 5) to the Director that the changes have been made.
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.
SECTION B: ANALYTICAL MONITORING REQUIREMENTS
A facility that retains exposed accumulations (either exposed to incident precipitation or exposed to
stormwater run on) of sawdust, wood chips, bark, mulch, or other similarly sized material on site for
more than seven (7) days is required to monitor and report all the site stormwater discharges for the
parameters in Table 1.
The permittee may petition the DEMLR Regional Office Supervisor to be excused from the required monitoring:
a) upon a DEMLR Compliance Evaluation Inspection, and;
b) on the basis that DEMLR concludes that taken as a whole, site -wide conditions support the
assessment of very limited risk of stormwater pollution from the site.
c) Among any other factors deemed relevant in his or her own considerations, the Regional Office
Supervisor shall consider whether the amount of accumulated exposed materials may be deemed de
minimis with respect to the potential to generate stormwater runoff pollutants. Given that all site
conditions may be relevant to the determination of what constitutes a de minimis amount, such
determinations shall be made on a 'case -by -case basis', and shall not be assumed to be generally, or
specifically, transferrable to any other permitted site, regardless of superficial similarities.
d) The Regional Office Supervisor will communicate any such determination in writing, and shall state
any qualifying conditions for the permittee's continuing release from monitoring. DEMLR's release
letter may remain in effect through subsequent reissued versions of this permit, unless the release
letter provides for other conditions or duration.
e) If released from monitoring, the permittee must still continue to submit semi-annual Discharge
Monitoring Reports, with the notation: "Released from Monitoring by DEMLR Regional Office."
If at any time there are changes to DEMLR's initial site assessment, or to the initial site operating
circumstances, the permittee must immediately begin analytical monitoring and reporting in accordance
with Tables 1 and 2, and must immediately inform the DEMLR Regional Office that analytical monitoring has
been instituted.
Part II Page 4 of 13

Permit No. NCG210000
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.

Footnotes:
1 Measurement Frequency: Twice per year (unless other provisions of this permit prompt monthly sampling) during a
measurable storm event, until either another permit is issued for this facility or until this permit is revoked or
rescinded. See Table 2 for schedule of monitoring periods through the end of this permitting cycle. If the facility is
monitoring monthly because of Tier Two or Three response actions under the previous General Permit, the facility
should continue a monthly monitoring and reporting schedule.
2 Grab samples shall be collected within the first 30 minutes of discharge.
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 DEMLR letter granting ROS shall be kept on site.
4 For each sampled measurable storm event, the total precipitation must be recorded. 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.
The permittee shall complete the analytical samplings in accordance with the schedule specified
below 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.
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
III, Section E). 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.

Footnotes:
1. Maintain semi-annual monitoring during the General Permit renewal process (unless other provisions of
this permit require monthly sampling). The applicant must continue monitoring until the renewed
Certificate of Coverage (COC) is issued.
2. If no discharge occurs during the sampling period, the permittee must record "No Flow" or "No Discharge"
within 30 days of the end of the sampling period.
3. Monitoring periods remain constant throughout the five-year term of the General Permit. For permittees
continuing with renewed coverage under this General Permit, Year 1 begins in Period 2 on August 1, 2018,
and for all permittees, Year 5 ends in Period 1 on July 31, 2023.
Failure to monitor and report semi-annually per permit terms may result in the Division requiring
monthly monitoring and reporting 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, for example, does not constitute failure to monitor, as long as it is properly
reported.
The permittee must report the results from each sample taken within the monitoring period (See Part III
E). 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.
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 implementation of the
permittee's SPPP. Exceedances of benchmark values require the permittee to increase monitoring and
reporting, increase management actions, increase record keeping, and/or install stormwater Best
Management Practices (BMPs) in a tiered program. See descriptions of Tier One, Tier Two, and Tier
Three response actions below. In the event that the Division releases the permittee from continued
monthly monitoring and reporting under Tier Two or Tier Three, DEMLR's release letter may remain in
effect through subsequent reissuance of this permit, unless the release letter provides for other
conditions or duration.

Tier One
If: The first valid sampling results are above a benchmark value, or outside of the benchmark range, for any
parameter at any outfall;
Then: The permittee shall:
1. 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 feasible: 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 feasible actions within two months of the inspection.
5. 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 actions, and the date
the selected actions were implemented.
6. Note: Benchmark exceedances for a different parameter separately trigger a tiered response.
Tier Two
If: The first valid sampling results from two consecutive monitoring periods (omitting periods with no discharge)
are above the benchmark values, or outside of the benchmark range, for any 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. 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. Alternatively, in lieu of steps 2 and 3, the permittee may, after two consecutive exceedances, exercise the
option of contacting the DEMLR Regional Engineer as provided below in Tier Three. The Regional Engineer
may direct the response actions on the part of the permittee as provided in Tier Three, including reduced or
additional sampling parameters or frequency.
S. Maintain a record of the Tier Two response in the SPPP.
6. Continue Tier Two response obligations throughout the permit renewal process.
Tier Three
If: The valid sampling results required for the permit monitoring periods exceed the benchmark value, or are
outside the benchmark range, for any specific parameter at any specific outfall on four occasions, the permittee
shall notify the DEMLR Regional Engineer in writing within 30 days of receipt of the fourth analytical results;
Then: The Division may but is not limited to:
• require that the permittee revise, increase, or decrease the monitoring and reporting frequency for some
or all of the parameters herein;
• require sampling of additional or substitute parameters;
• 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;
• require the permittee to continue Tier Three obligations through the permit renewal process.

Permit No. NCG210000
SECTION C: QUALITATIVE MONITORING REQUIREMENTS FOR STORMWATER
DISCHARGES
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 associated with
industrial activity regardless of representative outfall status. Qualitative monitoring shall be
performed semi-annually as specified in Table 4, and during required analytical monitoring events if
applicable (unless the permittee is required to perform further qualitative sampling per the
Qualitative Monitoring Response below). Inability to sample because of adverse weather
conditions must 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).
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.

Part II Page 8 of 13

Permit No. NCG210000
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 Stormwater Pollution Prevention Plan.
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, DEMLR 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;
• 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.
SECTION D: ON -SITE VEHICLE AND EQUIPMENT MAINTENANCE -- ANALYTICAL
MONITORING REQUIREMENTS
Facilities that have any vehicle maintenance activity occurring on -site which uses more than 55
gallons of new motor oil and/or hydraulic oil per month when averaged over the calendar
year shall perform analytical monitoring as specified below in Table 1. (See "Vehicle Maintenance
Activity" in Definitions.) All analytical monitoring shall be performed during a measurable storm
event at all stormwater discharge outfalls (SDOs) that discharge stormwater runoff from vehicle
maintenance areas, and in accordance with the schedule presented in Table 2. Sampling is not
required outside of the facility's normal operating hours.

Footnotes:
1 Measurement Frequency: Twice per year during a measurable storm event (unless other provisions of the
permit prompt monthly sampling), until either another permit is issued for this facility or until this permit is
revoked or rescinded. See Table 2 for schedule of monitoring periods through the end of this permitting
cycle. If the facility is monitoring monthly because of Tier Two or Three response actions under the
previous 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. When physical separation between
outfalls prevents collecting all samples within the first 30 minutes, sampling shall be begun within the first 30
minutes, and shall continue until completed.
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, unless representative outfall
status (ROS) has been granted. A copy of the letter granting ROS shall be kept on site.
4 For each sampled measurable storm event the total precipitation must be recorded. An on -site rain gauge
is required. Where isolated sites are unmanned for extended periods of time, a local rain gauge may be
substituted for an on -site reading.
The permittee shall complete the analytical samplings in accordance with the schedule specified
below in Table 2, unless adverse weather conditions prevent sample collection (see Adverse Weather
in Definitions). 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 I11, Section E). 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.
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, for example,
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 6. The benchmark
values in Table 6 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 descriptions of Tier
One, Tier Two, and Tier Three response actions below. In the event that the Division releases the
permittee from continued monthly monitoring under Tier Three, DEMLR's release letter may remain
in effect through subsequent reissuance of this permit, unless the release letter provides for other
conditions or duration.

SECTION E: SPECIAL CONDITIONS
A (1.) ELECTRONIC REPORTING OF MONITORING REPORTS [G.S. 143-215.1(b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and
program reports. The final NPDES Electronic Reporting Rule was adopted and became effective on
December 21, 2015.
NOTE: This special condition supplements or supersedes the following sections within Part III of this
permit (Standard Conditions for NPDES Permits):
• Section B. (5.) Signatory Requirements
• Section D. (6.) Records Retention
• Section E. (1.) Discharge Monitoring Reports
• Section E. (2.) Submitting Reports
1. Reporting Requirements [Supplements Section E. (1.) and Supersedes Section E.
ku
Effective December 21, 2016 or when the agency's electronic reporting system is able to accept
NPDES stormwater permit monitoring data, the permittee shall report discharge monitoring data
electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR) internet
application. NC DEMLR will notify permittees when eDMR is ready to accept stormwater
monitoring data.
Monitoring results obtained during the previous month(s) shall be summarized for each month
and submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. Until such time that the
state's eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation
(CROMERR), permittees will be required to submit all discharge monitoring data to the state
electronically using eDMR and also will be required to complete the eDMR submission by
printing, signing, and submitting one signed original and a copy of the computer printed eDMR to
the following address:
NC DEQ / Division of Water Resources
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the
facility being physically located in an area where less than 10 percent of the households have
broadband access, then a temporary waiver from the NPDES electronic reporting requirements
may be granted and discharge monitoring data may be submitted on paper DMR forms or
alternative forms approved by the Director. Duplicate signed copies shall be submitted to the
mailing address above. See "How to Request a Waiver from Electronic Reporting" section below.
Regardless of the submission method, the first DMR is due no later than 30 days from the date
the facility receives the sampling results from the laboratory.
2. How to Request a Waiver from Electronic Reporting
Part II Page 11 of 13

Permit No. NCG210000
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an
electronic reporting waiver, a permittee must first submit an electronic reporting waiver request
to the Division. Requests for temporary electronic reporting waivers must be submitted in
writing to the Division for written approval at least sixty (60) days prior to the date the facility
would be required under this permit to begin submitting monitoring data and reports. The
duration of a temporary waiver shall not exceed 5 years and shall thereupon expire. At such time,
monitoring data and reports shall be submitted electronically to the Division unless the permittee
re -applies for and is granted a new temporary electronic reporting waiver by the Division.
Approved electronic reporting waivers are not transferrable. Only permittees with an approved
reporting waiver request may submit monitoring data and reports on paper to the Division for
the period that the approved reporting waiver request is effective.
Information on eDMR and the application for a temporary electronic reporting waiver are found
on the following web page:
https://deq.nc.gov/about/divisions/water-resources/edmr
3. Signatory Requirements [Supplements Section B. (5.) (b) and Supersedes Section B.
(5.) (d)]
All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part
III, Section B. (5.) (a) or by a duly authorized representative of that person as described in Part II1,
Section B. (5.) (b). A person, and not a position, must be delegated signatory authority for eDMR
reporting purposes.
For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR user
account and login credentials to access the eDMR system. For more information on North
Carolina's eDMR system, registering for eDMR and obtaining an eDMR user account, please visit

Part III Page 5 of 10

Permit No. NCG210000
8. Annual Administerine and Compliance Monitoring Fee Reauirements
The permittee must pay the administering and compliance monitoring fee within 30 (thirty) days
after being billed by the Division. Failure to pay the fee in timely manner in accordance with 15A
NCAC 2H .0105(b)(2) may cause this Division to initiate action to revoke coverage under the general
permit.
SECTION C: OPERATION AND MAINTENANCE OF POLLUTION CONTROLS
Proper Operation and Maintenance
The permittee shall at all times properly operate and maintain all facilities and systems of treatment
and control (and related appurtenances) which are installed or used by the permittee to achieve
compliance with the conditions of this permit. Proper operation and maintenance also includes
adequate laboratory controls and appropriate quality assurance procedures. This provision requires
the operation of back-up or auxiliary facilities or similar systems which are installed by a permittee
only when the operation is necessary to achieve compliance with the conditions of this permit. [40
CFR 122.41(e)]
Need to Halt or Reduce Not a Defense
It shall not be a defense for a permittee in an enforcement action that it would have been necessary
to halt or reduce the permitted activity in order to maintain compliance with the condition of this
general permit. [40 CFR 122.41(c)]
Bypassing of Stormwater Control Facilities
Bypass is prohibited, and the Director may take enforcement action against a permittee for bypass
unless:
a. Bypass was unavoidable to prevent loss of life, personal injury or severe property damage; and
b. There were no feasible alternatives to the bypass, such as the use of auxiliary control facilities,
retention of stormwater or maintenance during normal periods of equipment downtime or dry
weather. This condition is not satisfied if adequate backup controls should have been installed in
the exercise of reasonable engineering judgment to prevent a bypass which occurred during
normal periods of equipment downtime or preventive maintenance; and
c. The permittee submitted notices as required under, Part III, Section E of this general permit.
If the Director determines that it will meet the three conditions listed above, the Director may
approve an anticipated bypass after considering its adverse effects.
SECTION D: MONITORING AND RECORDS
Representative Sampling
Samples collected and measurements taken, as required herein, shall be characteristic of the volume
and nature of the permitted discharge. Analytical sampling shall be performed during a measureable
storm event. Samples shall be taken on a day and time that is characteristic of the discharge. All
samples shall be taken before the discharge joins or is diluted by any other waste stream, body of
water, or substance. Monitoring points as specified in this general permit shall not be changed
without notification to and approval of the Permit Issuing Authority. [40 CFR 122.41(j)]
2. Recording Results
For each measurement or sample taken pursuant to the requirements of this general permit, the
permittee shall record the following information [40 CFR 122.41]:
a. The date, exact place, and time of sampling or measurements;
b. The individual(s) who performed the sampling or measurements;
Part III Page 6 of 10

Permit No. NCG210000
c. The date(s) analyses were performed;
d. The individual(s) who performed the analyses;
e. The analytical techniques or methods used; and
f. The results of such analyses.
Flow Measurements
Where required, appropriate flow measurement devices and methods consistent with accepted
scientific practices shall be selected and used to ensure the accuracy and reliability of measurements
of the volume of monitored discharges.
Test Procedures
Test procedures for the analysis of pollutants shall conform to the EMC regulations published
pursuant to NCGS 143-215.63 et. seq, the Water and Air Quality Reporting Acts, and to regulations
published pursuant to Section 304(g), 33 USC 1314, of the Federal Water Pollution Control Act, as
Amended, and Regulation 40 CFR 136.
To meet the intent of the monitoring required by this general permit, all test procedures must
produce minimum detection and reporting levels and all data generated must be reported down to
the minimum detection or lower reporting level of the procedure. If no approved methods are
determined capable of achieving minimum detection and reporting levels below general permit
discharge requirements, then the most sensitive (method with the lowest possible detection and
reporting level) approved method must be used.
Representative Outfall
If a facility has multiple discharge locations with substantially identical stormwater discharges that
are required to be sampled, the permittee may petition the Director for representative outfall status.
If it is established that the stormwater discharges are substantially identical and the permittee is
granted representative outfall status, then sampling requirements may be performed at a reduced
number of outfalls.
Records Retention
Qualitative monitoring shall be documented and records maintained at the facility along with the
Stormwater Pollution Prevention Plan (SPPP). Copies of analytical monitoring results shall also be
maintained on -site or be available electronically to a DEMLR inspector upon request. The permittee
shall retain records of all monitoring information, including
o all calibration and maintenance records,
o all original strip chart recordings for continuous monitoring instrumentation,
o copies of all reports required by this general permit,
o copies of all data used to complete the Notice of Intent to be covered by this general permit.
These records or copies shall be maintained for a period of at least 5 years from the date of the
sample, measurement, report or Notice of Intent application. This period may be extended by
request of the Director at any time. [40 CFR 122.41] If this volume of records cannot be maintained
on -site, the documents must be made available to an inspector upon request as immediately as
possible.
Inspection and Entry
The permittee shall allow the Director, or an authorized representative (including an authorized

SECTION E: REPORTING REQUIREMENTS
1. Discharge Monitoring Reports
Samples analyzed in accordance with the terms of this general permit shall be submitted to the
Division on Discharge Monitoring Report (DMR) forms provided by the Director. DMR forms are
available on the Division's website (https:/Zdeg.nc.gov/about/divisions/energy-mineral-land-
resources/npdes-industrial-stormwater). Submittals shall be delivered to the Division no later than
30 days from the date the facility receives the sampling results from the laboratory.
When no discharge has occurred from the facility during the report period, the permittee is required
to submit a discharge monitoring report, within 30 days of the end of the specified sampling
period, giving all required information and indicating "NO FLOW" as per NCAC T15A 0213.0506.
If the permittee monitors any pollutant more frequently than required by this general permit using
test procedures approved under 40 CFR Part 136 and at a sampling location specified in this general
permit or other appropriate instrument governing the discharge, the results of such monitoring shall
be included in the data submitted on the DMR. [40 CFR §122.41(1)]
The permittee shall record the required qualitative monitoring observations on the SDO Qualitative
Monitoring Report form provided by the Division and shall retain the completed forms on site.
Qualitative monitoring results should not be submitted to the Division, except upon DEMLR's specific
requirement to do so. Qualitative Monitoring Report forms are available at the website above.

General Description:
G&G Forest Products — Harmony, NC receives and processes wood materials. The site is
used as a saw mill facility, but the facility is largely used for receiving wood lumber which is
processed by sawing and drying, storage and distribution.
The activities involve receiving receiving lumber, unloading, stacking in storage piles,
sawing, sizing, drying and loading for shipment off site.
The majority of the activities occur indoors with little exposure to storm runoff. Activities
occurring outdoors are primarily the loading and unloading operations plus storage.
Operating areas were observed to be reasonably neat and well organized which reflect
good housekeeping procedures.
Trash dumpsters are located on the site and are used to accumulate miscellaneous trash
and debris that are a consequence of operations. A private carrier removes the trash for
disposal off site at the county landfill. The dumpsters have covers and side doors that are
kept closed when not in immediate use in order to minimize potential for exposure. These
areas appeared to be well maintained with no evidence of any significant leakage or
spillage of extraneous materials.
Overall, the facility appears to be in good condition and there is obviously an effort to
maintain clean, orderly areas outside the plant buildings. However there are some areas
where excess materials have been allowed to accumulate. These do not represent a
significant or imminent threat for contaminating runoff but should be corrected with
improved housekeeping procedures to lessen the potential for moderate to minor
contributions to storm runoff contaminants. In general, the observed procedures being
employed reflect best management practices that are at the heart of the intent of federal
and state storm water management programs.
In the following pages, more specific descriptions of plant conditions, practices and
recommendations are provided.

Page 2
Summary of Stormwater Pollution Prevention Plan Requirements:
The stormwater pollution prevention plan (SWP3) must be fully reviewed to insure that all
requirements are met and the intent fulfilled, The plan identifies a pollution prevention team
who, together with company management, are responsible for administering the plan.
The team members may be changed with additions and deletions but such changes should
be documented in the plan.
The following specific requirements are referenced in the remainder of the plan but are
highlighted here to insure a clear understanding of these major requirements:
1) Employee training (Ref. Appendix B) - Required at least annually for all
employees. (Note: A brief training handout is included in Appendix B that
may be used as a tool for training.)
2) Site Compliance /Plan Adequacy Evaluation (Ref. Appendix C) - Required
annually. (Note: This service is available to be done by the consultant, BREC,
P.A. if the company would like.)
3) SWP3 Certification (Ref. Appendix E) - Requires plant authority signature.
4) Visual Examination (Qualitative Analysis) - ( Ref. Appendix D) — Required
semi-annually. (Note; This service is available to be done by the consultant,
BREC, P.A. if the company would like.)
5) Visual Site Inspection (Ref. Appendix F) — Required twice per year. (Note:
This service is available to be done by the consultant, BREC, P.A. if the
company would like.)
6) Stormwater Monitoring (Quantitative Analysis)(Ref. Appendix K) - A copy of
the general permit is included in Appendix H. The monitoring requirements in

Page 3
this permit are for semi-annual sampling if significant vehicle maintenance
activities occur or if piles of wood bark, dust and similar wood waste
materials are left exposed without removing for more than seven (7) days.
Significant vehicle maintenance activities are defined as maintenance
activities which result in the use of an average of 55 gallons of new motor
oil per month. If the facility uses an average of 55 gallons or more of new
motor oil per month, then it is subject to the sampling requirements and
must collect samples for analysis at a state certified laboratory twice per
year, once in the first half (January 1 — June 30) and once in the second
half (July 1 — December 31) each year at each outfall during a measurable
storm event as defined in the permit.
Or, if piles of wood bark, dust, chips and similar wood waste materials are
left exposed without removing for more than seven (7) days, then it is
subject to the sampling requirements and must collect samples for analysis
at a state certified laboratory twice per year, once in the first half (January 1
— June 30) and once in the second half (July 1 — December 31) each year
at each outfall during a measurable storm event as defined in the permit.
Based on the observations during the site evaluation, it appears that G & G
does keep piles of wood bark, dust, chips and similar wood waste materials
that are left exposed without removing for more than seven (7) days.
Therefore G & G is required to collect samples for analysis from each of the
three (3) identified outfalls and submit the results of analysis from a state
certified laboratory twice per year. The results of these analyses must be
submitted to the state using the approved monitoring report form (See
Appendix K.) Results must be submitted within 30 days of receiving the
results from the laboratory.
There is a provision within the permit wherein G & G may petition the NC
Division of Water Quality, Mooresville Office of Water Quality Protection

Page 4
to be excused from the sampling requirements. This is only an option if there
is no vehicle maintenance activities on site that subject the facility to
sampling requirements (in short, the facility must use less than an average of
55 gallons of new oil per month). If this petition is made and if after
inspection by NC Division of Water Quality, the state may excuse G & G
from sampling requirements.
However, regardless of the above possible relief from sampling requirements
due to materials exposure, G & G will still be subject to sampling
requirements if an average of 55 gallons or more of new oil are used per
month for vehicle maintenance.
The sampling requirements apply to all three (3) outfalls. However, it is
recommended that G & G petition the state to consider that one outfall (I
suggest outfall 001) is representative of the stormwater runoff conditions
for the entire site. If approved, then G & G would only be required to
sample the one outfall as opposed to doing all three as otherwise is required
by the permit. This would at least, greatly reduce the difficulty and expense
of collecting samples. Please note that, regardless of whether the state does
or does not approve representative outfall status, all outfalls are still required
to be examined visually, twice per year as described above.
(Note: These services are available to be done by the consultant, BREC,
P.A. if the company would like.)
8) Re -Certification of evaluation of stormwater outfalls for presence of non-
stormwater discharges (Ref. Appendix J) The site must be reevaluated each
year to confirm that there are no illicit, non-stormwater discharges connected
to any of the stormwater discharge outfalls. This must be certified using the
form provided in Appendix J. (Note: This service is available to be done by
the consultant, BREC, P.A. if the company would like.)
