3. Purpose and Scope
The purpose of the plan is to identify sources of toxic organics in the plant wastewater and describe
controls necessary to ensure that these chemicals are not intentionally or accidentally discharged in
the facility wastewater system. Refer to Appendix A for the toxic organic list.

a. Process Description
The Southwire Huntersville Plant manufactures medium to heavy duty underground cable using
vertical continuous vulcanization (VCV). The manufacturing process begins at the wire drawing
line in which copper or aluminum rod is drawn down to.smaller wire size specifications. At
stranding, the copper or aluminum wire is twisted to form a conductor. The conductor can be
additionally twisted together at the drum twisting line for large size conductors. At VCV line and
tower, up to three (3) layers of insulation are extruded onto the conductor usually involving an
inner layer of insulation / black polyethylene conductor shield, a layer of colorless insulation, and
a black outer layer / black polyethylene insulation shield. Ground wire is added over the cable at
the screening line. At the jacketing line, an outer copper shield layer is added over the cable and
an outer layer black polyethylene insulation shield is extruded onto the cable.
The wire draw line uses oil/ water / emulsion solutions from a closed system to draw the wire
down. The water solution is changed out periodically in which the solution is pumped out a
cleaning tank and into totes or vacuum truck for waste to energy disposition.
Stranding, screening and drum twist lines do no require water.
The VCV process located at the tower utilizes a closed loop water and nitrogen system to cure
the insulation layers from the extrusion process. Water is recirculated and stored in a recirculation
tank. Waste process water is collected in a clean out tank. When full, the waste water is pumped
into a tote for a waste to energy disposition. Water that overflows during change -over is captured
in a sump pit and transferred to the sewer line.
Water is used to cool the cable from the extrusion process in the jacketing line. This is a closed
loop system. Water is not discharged. The jacketing line is in the main manufacturing area.
b. Inventory of Total Toxic Organic Chemicals present on site
Currently there are no Toxic Organic Chemicals present on site. See "Annual TTO Review" in
"section c" below.
c. Management Procedures and Engineering Measures for assuring that toxic organics do not spill
or leak into stormwater.
• Chemical Approval:
Prior to purchasing, a new chemical is reviewed through an approval process in Southwire's
Safetec SDS system. An EHS review is performed on the chemical to determine the
environmental impact, including TTO.
• Safety Process Review:
All new processes or significant modifications to processes are reviewed through a
Management of Change procedure. Any new chemicals are identified and reviewed for
environmental impact, including TTO.
• Employee Training:
Annually, employees are trained on Spill, Stormwater, and Waste Management procedures.
Spill clean-up, chemical storage and chemical waste management are topics that are
reviewed.

• Engineering Controls:
Liquid chemicals are stored inside the plant or within building structures with spill
containment, inside flammable cabinets, and/or in double wall design containers.
• Spill Control:
Response to spills is immediate and considers containment, proper clean-up of spill, proper
disposal of waste and notification to Southwire and regulatory officials. Storage of chemicals
follows practices identified in "Engineering Controls" in this plan.
• Annual TTO Review:
Annually using the Southwire Safetec database, the CAS numbers of chemicals for this site is
compared to the TTO list (Appendix A) for usage of TTO chemicals. This Solvent
Management Plan is reviewed annually and updated when applicable.
With no inventory of TTO's and no discharging of chemicals into stormwater, the following
statement will be included for the year's discharge monitoring reports after validation:
Based upon my inquiry of the person or persons directly responsible for managing
compliance with the permit monitoring requirement for total toxic organics (TTO), I certify
that to the best of my knowledge and belief, no leak, spill, or dumping of concentrated
toxic organics into the stormwater or onto areas which are exposed to rainfall or
stormwater runoff has occurred since filling the last discharge monitoring report. 1 further
certify that this facility is implementing all the provisions of the Solvent Management Plan
included in the Stormwater Prevention Plan.
