1.0 INTRODUCTION
DCN Cables, A Southwire Company (DCN) is submitting a Notice of Intent (N01) for the North Carolina
Pollutant Discharge Elimination System (NPDES) General Permit No. NCG030000. The N01 is for storm
water discharges associated with Standard Industrial Classification (SIC) 3351 for industrial uses. The
NDPES multi -sector permit requires the preparation and maintenance of a Stormwater Pollution
Prevention Plan (SWPPP).
This SWPPP must be revised:
1. Whenever there is a change in design, construction, operation, or maintenance that has a
significant effect on the potential for the discharge of pollutants; and/or
2. If the SWPPP proves to be ineffective in eliminating or minimizing pollutants from identified
sources.
New construction, especially which involves grading and/or significant movement of soils, may require an
update to the SWPPP. Such activities should also be conducted in a manner that mininflLes erosion and
sediments from entering the waters of the State of North Carolina during precipitation events.
The revision date shall be updated in the revised sections when this SWPPP is revised. When changes to
this SWPP are required, they must be made within 60 days of discovering a required change.
DCN will maintain this SWPPP, including records and a copy of the NPDES General Permit, on -site and/or
made readily available for review by authorized North Carolina Department of Environmental Quality
personnel upon request.

4.0 POTENTIAL POLLUTANT AND SOURCE DESCRIPTION
4.1 GENERAL FAc1LiTY DESCRIPTION
The Site is located northwest of Youngsville, North Carolina and is situated on the southeastern corner of
the intersection of weathers St. and Mosswood Blvd. The Site consists of 60,000 W of leased space which is
approximately half of the Northern portion of the facility that is situated at 130 Mosswood Blvd. DCN
industrial activities are contained to 3.3 acres of land and is bounded to the north by Mosswood Blvd, south
by East West Manufacturing (other building tenant) , the east by Weathers St. and west by an empty lot and
power distribution right of way.
The Site is located on the 1:24 000- scale United States Geological Survey (USGS) 7.5-minute 1984
Henderson, North Carolina Quadrangle topographic map (Figure 2). The Site is situated at an elevation of
approximately 453 feet above mean sea level (msl). Regional topography surrounding the Site slopes slightly
to the southeast towards the Richland Creek.
DCN currently operates the Site for the production of power cables primarily for data centers. Currently
on -site operations include general assembly of electrical connectors to eliminate time/work on a job site
for an electrical installation. Finished prepared assemblies are distributed to job sites. There is no
fabrication or manufacturing currently being conducted at the site.
The Site improvements are comprised Of a Single warehouse building of which DCN occupies approximately
half (60,000 ft?), The developed exterior area consists of concrete and asphalt parking/storage, concrete
driveways around the structures with the remaining areas consisting of grass perimeter.
4.2 DRAINAGE
Stormwaterflow on the majority of the Site travels via sheet flow and follows the general topography of the
Site, which is generally flat with a slight slope away from the on -site buildings.
• Runoff from the west of the Site follows the general topography and flows in the direction of west,
Southwest towards Weathers St.
• Runoff from the north of the Site follows the general topography and flows in the direction of East,
Southeast.
• Runoff from the east of the Site follows the general topography and flows South, southeast directly
towards the intermittent portion of Richland Creek.
4.3 INVENTORY OF MATERIALS
Exposed materials are items that have the potential to come in contact with precipitation and could cause
a release of a pollutant into stormwater runoff. These materials include, but are not limited to, materials
stored in drums, aboveground storage tanks (ASTs) and other similar containers. Materials located at the
facility that have the potential to be exposed to precipitation or have the potential to be released to the
environment are shown on Figure 3 and summarized below:
Two 40 Yard Roll off Containers, containing scrap metal and broken wood, respectively,
Significance: The containers are generally leak proof and present a low likelihood of a
release. However, occasionally containers can be delivered with damage and are not leak
proof, it is Southwire best practice that the containers are stored within secondary

containment area and covered during non -working hours and/or during periods of
precipitation to prevent the potential to affect storm -water runoff.
Two 8 Yard Waste containers containing general office and breakroom waste.
Significance: The containers are generally leak proof and present a low likelihood of a
release. They are equipped with a slanted closing; it is 5outhwire practice that the
containers are stored within secondary containment area and covered during non-
working hours and/or during periods of precipitation to prevent the potential to affect
storm -water runoff.
Wood Reels
Significance: Containers, racks and other transport platforms (e.g., wooden pallets) used
for the storage or conveyance of final products can be stored outside, providing the
containers, racks and platforms are pollutant -free. It is 5outhwire best practice to store
in a way that protects them during periods of precipitation to prevent the potential to
affect storm -water runoff,
• Wood Pallets
Significance: Containers, racks and other transport platforms (e.g., wooden pallets) used
for the storage or conveyance of final products can be stored outside, providing the
containers, racks and platforms are pollutant -free. It is Southwire best practice to store
in a way that protects them during periods of precipitation to prevent the potential to
affect storm -water runoff.
Materials should be stored within a building and/or under a roof/cover, and within secondary
containment when practical, to reduce the likelihood of being exposed to stormwater. The inventory of
exposed materials shall be updated within 30 days whenever significant changes in the types of materials
that are exposed to precipitation occur.
4.4 SPILLS AND LEAKS
A record of reportable spills where a leak, spill or other release containing a hazardous substance or oil in
an amount equal to or in excess of a reportable quantity established under either 40 CFR Part 110, 40 CFR
Part 117, or 40 CFR Part 302 occurs during a 24-hour period in areas exposed to precipitation during the
last three years shall be included in this SWPPP. The list shall be updated on an annual basis to include
any additional spills and leaks.
Currently, there has not been a reportable spill at the Site.

5.0 POLLUTIONS PREVENTION MEASURES AND CONTROLS
Best Management Practices (BMPs) are practices developed to reduce the potential discharge of
pollutants into stormwater. BMPs for operations at the Site are presented herein.
S.1 GOOD HOUSEKEEPING MEASURES
Good housekeeping measures are designed to reduce pollutant contact with stormwater through the
proper handling and maintenance of material (product and waste) storage areas, equipment storage areas
and equipment maintenance areas. Some of the good housekeeping procedures that are employed at the
facility are summarized below.
• Schedule regular cleaning of impervious areas around the perimeter of the buildings to remove
dust, debris or any other particulate matter that may accumulate.
• Immediately clean leaks and spills from loading/unloading operations and material used in
cleanup is disposed of properly;
• Oil filled equipment is either drained before work/storage, is kept within secondary containment
and/or stored under cover whenever possible;
• Regular inspections of work areas, storage areas, facility equipment, chemical/oil storage areas
and employee parking areas;
• Exposed storage areas will be kept neat and orderly so that leaks or spills can be easily found
and addressed. Additionally, the area will be cleaned regularly to ensure its properfunction and
minimize the possibility of a leak or spill;
• Trash receptacles are kept closed and inside buildings or under cover to prevent exposure to
precipitation; and
• Facility personnel participate in keeping the grounds clean and clear of unnecessary trash and
debris to maintain an orderly and safe working environment.
5.2 SPILL PREVENTION AND RESPONSE PROCEDURES
A spill or leak from the on -site drums ortanks is the most significant potential source to affect stormwater.
Oil storage drums should be placed into secondary containment, such as spill pallets, to contain a potential
release. Spill kits containing oil absorbent materials (pads, "socks", booms, granular material, etc.) should
be placed near any area where oil products are stored or used. Additionally, equipment stored outside
should: be emptied of oils and lubricants when practical; have drip pans located beneath oil filled
pieces/equipment; and be covered with impermeable tarps when practical. Oil filled equipment should
be stored indoors or under cover if possible.
Small amounts of material spilled within the shop area should be collected with granular sorbent material
or other means. Used sorbents should be placed into storage drums pending proper disposal. Small
amounts of material spilled or leaked outdoors should be placed into storage drums pending proper
disposal. DCN will make reasonable attempts to remove surface staining. Leaks and spills of other
materials shall be handled as instructed by the manufacturer and/or the Safety Data Sheet (SDS).

5.3 EROSION CONTROL MEASURES
Sediment and erosion controls are designed to reduce the introduction of sediment from erosion into
surface water bodies. Personal vehicles should be parked on the asphalt or gravel parking lot. Silt fences
or other erosion control measures may become necessary if precipitation causes excess erosion. The Site
has a slight slope and erosion/sedlment Is not expected to be an issue during nonnal operations or
ordinary precipitation.
5.4 PREVENTATIVE MAINTENANCE
Preventive maintenance includes periodic inspections to determine the present condition of equipment
and structural controls. These periodic visual walkthrough inspections serve as a BMP for routine
observations of operations and conditions of major equipment to reduce the possibility of affect to
stormwater. This includes both equipment owned by the facility as well as any equipment and parts
brought on -site for repairs/refurbishing that is owned by others. Equipment in need of
repair/replacement should be brought to the attention of the SWPPP Administrator.
5.5 EMPLOYEE TRAINING
Employee training is essential for effective implementation of the SWPPP. Employee training under the
SWPPP will include personnel with pollution prevention responsibility. Employees will be informed of the
components of the SWPPP; including how and why each task is to be implemented. Tasks to include during
training are:
• Proper material management and handling procedures for specific chemicals kept at the facility;
• Spill prevention methods;
• Spill clean-up techniques and the location of materials and equipment necessary for clean up;
• Spill reporting procedures; and
+ Discussion of good housekeeping measures, BMPs and goals of the SWPPP and how to improve
these.
Training will take place concurrently with an annual SWPPP meeting and be given by DCN or their
designee. Training records will be maintained with this SWPPP. The goal of the training is to increase the
awareness of personnel and make personnel more capable of preventing spills, reducing pollutant loads
in stormwater runoff and recognizing situations and site conditions that may contribute to stormwater
pollution.
5.6 INSPECTIONS AND MONITORING
Regular inspections are an essential component of stormwater protection.
5,6.1 PERIODIC INSPECTIONS
Qualified personnel, who are familiar with the facility and its activities shall perform quarterly inspections
ul pollution control measures and determine the effectiveness of the SWPPP. The inspections shall
document, in a summary report, the effectiveness of Sections 4.1 through 4.4 of the SWPPP, revisions or
additional measures necessary to increase effectiveness and a time frame for implementing these
measures. A periodic inspection checklist is included as Attachment 1.

STORMWATER POLLUTION PREVINTION PLAN
DCN cables DCN CABLES, A SOUTHWIRE COMPANY
A south vfre company 10 JUNE 2021
When revisions or additions to the SWPPP are recommended as a result of inspections, a summary
description including necessary time frames required to implement the changes shall be attached to the
inspection checklist.
5.6.2 QUARTERLY VISUAL MONITORING
Stormwater discharges from each outfall must be visually examined in a well -lit area on a quarterly basis
and documentation of the following observations must be recorded: the date and time, names of
personnel, the nature of the discharge (e.g. runoff, snow melt), discharge color, clarity, floating solids,
settled solids, suspended solids, foam, oil sheen, other obvious indicators of storm water pollution and
any noticeable odors.
The SWMP Team will review results of the examination. The team will investigate and identify probable
sources of any observed stormwater contamination. The SWPPP will be modified as necessary to address
the conclusions of the SWPPP Team. Areas that should be inspected include near any petroleum/chemical
storage areas (tanks, drums, totes, etc.), near metal shavings containers, the wash rack area and areas
where work is performed where parts and equipment are exposed to precipitation.
5.6.3 BENCHMARK MONITORING
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All analytical
monitoring shall be performed during a storm event that results in an actual discharge from the permitted
site outfall.
Sampling shall be conducted during discharges of runoff: from a representative storm event with at least
0.1 inch of measured precipitation that occurs with a minimum interval of at least 72 hours from the
preceding measurable storm event. Semiannual sampling must be initiated during the first monitoring
period (January through June) in the first calendar year (January through December) following permit
issuance and then once during each semiannual monitoring period (i.e., January through June and July
through December).
DCN shall compare monitoring results to the benchmark values in Table 1. In the event of an exceedance
of the benchmark values DCN will increase monitoring, increase management actions, increase record
keeping, and/or install Stormwater Control Measures (SCM) in a tiered program as described in section B
of the issued stormwater permit.
Daily rainfall amounts during storm events should be monitored. Monitoring and recording may be
temporarily suspended if the required inspection has been conducted. Sampling will be conducted at the
outfall located to the Southeast of the DCN. Results of analyses for sampling shall be submitted to DEQ
before March 31st of each year following sample collection. The report must be completed on the
STORMWATER DISCHARGE OUTFALL (SDO) ANNUAL SUMMARY DATA MONITORING REPORT (DMR) /
SPPP Annual Update DATA REVIEW FORM. Submissions through a-DMR are required bylan 1, 2022, paper
submissions are acceptable until then.

SWPPP. This evaluation is in addition to other routine inspections required and shall be conducted at least
once per year. The evaluation shall include:
• Inspection of areas identified in Section 4.3;
• Inspection of structural controls including maintenance and effectiveness;
• Inspection of non-structural controls including BMP effectiveness, good housekeeping measures
and spill prevention;
• Inspection of reasonable accessible areas immediately downstream of each storm water outfall;
• Review of records required by the permit (Multi Sector General Permit, Part V, Sector AA).
An inspection checklist is included as Attachment 1.
Within 30 days of performing the annual site compliance evaluation, DCN will prepare a report, which
includes a narrative discussion of the facility's compliance with the SWPPP.
5.6.5 RECORDKEEPING AND INTERNAL REPORTING PROCEDURES
Records of inspections will be maintained and document the date of the inspection, the inspector's name,
identity of each area visually inspected, problems identified cif any) and steps taken to remedy problems
identified. Records will be maintained with this SWPPP at least five years after the inspection. If non-
compliance incidents are not discovered, the report shall contain a certification that the facility is in
compliance with the SWPPP.
If an incident of non-compliance is identified, then the report shall include necessary actions to remedy
the non-compliance and the SWPPP shall be updated in accordance with Section E Part 9.A of the NPDES
General Permit, included as Attachment 5. The identified actions should be completed as soon as possible.
5.7 MANAGEMENT OF RUNOFF
Rain flow on the majority of the facility travels via sheet flow and follows the general topography of the Site,
which is generally flat with a slight slope away from the on -site buildings. Runoff from the Site travels

cables

through drainage ditches and ultimately reaches Richland Creek. Detailed runoff' flow directions are shown
on Figure 3.
5.8 SPILL REPORTING
Spills should be reported to the SWPPP Administrator and appropriately documented.
Spills that result in chemical, oil, petroleum product, sewage, etc., in excess of reportable quantities and
threaten waters of the State of North Carolina (which includes surface waters, ground water and dry
gullies or storm sewers leading to surface water) shall be reported to the DEMLR Regional Office within
24 hours. Additionally, the permittee shall report spills including: any oil spill of 25 gallons or more, any
spill regardless of amount that causes a sheen on surface waters, any oil spill regardless of amount
occurring within 100 feet of surface waters, and any oil spill less than 25 gallons that cannot be cleaned
up within 24 hours.
Any information shall be provided orally within 24 hours from the time DCN became aware of the
circumstances. A written submission shall also be provided within S days of the time DCN becomes aware
of the circumstances. The written submission shall contain a description of the noncompliance, and its
causes; the period of noncompliance, including exact dates and times, and if the noncompliance has not

6.0 RECOMMENDATIONS
The recommendations summarized below are based upon the site inspection conducted by
Kenneth Playford on June 07, 2021.
1) Cover or protect open top waste containers during precipitation events. This can be dome by
the installation of a metal structure or using a cover. Only adding waste during dry conditions
2) Work with the waste and scrap metal vendor to provide "liquid tight" roll off containers.
3) Pallets and wooden reels can be stored outside but should be inspected on a regular basis to
ensure that they are not contaminated with any oil, chemical or other particulate matter that
would affect the quality of stormwater flowing off the site. These materials can also be
protected by tarp or structure.
4) The site could increase the waste pick up frequency to lower the probability of a container
having material exposed to stormwater.
