Section 1. Facility Activities and Process:
DyStar Carolina Chemical is a chemical manufacturing facility producing chemicals used to make
fabrics stronger, softer, shrink-free, washable, and water repellent. Other products at this facility are
adhesives,paper products, and sulfated oils. Numerous raw chemicals are used in the production process
and are stored in drums, totes, and in bulk. These raw materials are received at loading docks by tanker
truck and stored either inside the warehouse or in outdoor ASTs. The final products are stored in bulk
ASTs in warehouses and shipped off-site via tanker truck, drums, or totes.
A large percentage of stormwater runoff is contained in a spill containment system (two 90,000-gallon
spill basins that receive all drainage from the tank farm area and building areas), which routes to the
WWTP, or during significant storm events to a flow buffer basin adjacent to the WWTP (stormwater
routed from holding basins to flow buffer rather than to the WWTP). The system is equipped with a
bypass valve (per the permittee the valve always remains closed). Stormwater from non-process areas is
not routed to the spill containment basins. All stormwater runoff not diverted to the spill containment
system travels off-site from eight(8) drainage areas.
Oil storage at the facility consists primarily of two No. 2 fuel oil tanks, ten oil based chemical storage
tanks, one oil reservoir, one 1,100-gallon diesel tank, six transformers, waste oil drums, and
miscellaneous lubricating oil drums.

Page 2 of 7

Why Industrial Sites with Stormwater are Subject to a Permit: Federal NPDES regulations define
stormwater discharge associated with industrial activity in 40 CFR §122.26 (b)(14) as: "the discharge
from any conveyance that is used for collecting and conveying storm water and that is directly related to
manufacturing,processing or raw materials storage areas at an industrial plant. The term does not
include discharges from facilities or activities excluded from the NPDES program under this part 122.
For the categories of industries identified in this section, the term includes, but is not limited to, storm
water [sic] discharges from industrial plant yards; immediate access roads and rail lines used or traveled
by carriers of raw materials, manufactured products, waste material, or byproducts used or created by
the facility; material handling sites; refuse sites; sites used for the application or disposal of process
waste waters (as defined at part 401 of this chapter); sites used for the storage and maintenance of
material handling equipment; sites used for residual treatment, storage, or disposal; shipping and
receiving areas; manufacturing buildings; storage areas (including tank farms) for raw materials, and
intermediate and final products; and areas where industrial activity has taken place in the past and
significant materials remain and are exposed to storm water. For the purposes of this paragraph, material
handling activities include storage, loading and unloading, transportation, or conveyance of any raw
material, intermediate product, final product, byproduct or waste product. The term excludes areas
located on plant lands separate from the plant's industrial activities, such as office buildings and
accompanying parking lots as long as the drainage from the excluded areas is not mixed with storm
water [sic] drained from the above described areas."
Section 2. Monitoring Information and Compliance History:
• December 2017 to August 2023, benchmarks exceeded for:
o SW006: TSS Ix
o SW007: COD Ix
• NOV-2023-PC-0445 issued 8/25/2023 for failure to submit permit renewal application
Threatened/Endangered Species:
In the nearby vicinity, threatened and endangered species include: Carolina Heelsplitter(Lasmigona
decorate; NC status: E; Federal status: E), Georgia Aster(Symphyotrichum georgianum; NC status: T;
Federal status: C), and Tall Larkspur(Delphinium exaltatum; NC status: T).
Section 3. Proposed Monitoring for Stormwater Discharges:
The Division considered potential pollutants from past and present industrial activities and data was
submitted for December 2017 to August 2023. Quantitative sampling included pH, TSS, O&G, and
COD.
Parameters are based on potential pollutants in the drainage area, sampling results, and in some cases,
dependent upon future activities (e.g., ash removal through the drainage area). Below is a table of the
proposed monitoring for each outfall at the DyStar Carolina Chemical site.

Stormwater Benchmarks and Tiered Response: Rather than limits,North Carolina NPDES
Stormwater permits contain benchmark concentrations. Stormwater benchmarks are numerical action
levels for stormwater monitoring. Benchmarks are not effluent limits, and benchmark exceedances are
not permit violations. Benchmarks provide facilities a tool for assessing the significance of pollutants in
stormwater discharges and the effectiveness of best management practices (BMPs). Benchmark
concentrations are intended as guidelines for the facility's development and implementation of the
Stormwater Pollution Prevention Plan (SWPPP).
Page 4 of 7

Benchmark exceedances require the permittee to increase monitoring, increase management actions,
increase record keeping, and/or install stormwater BMPs in a tiered program. The permit establishes a
tiered approach to specify actions the permittee must take in response to analytical results above
benchmark concentrations. The tiered structure of the permit provides the permittee and DEMLR wide
flexibility to address issues that may arise with one or more parameters and/or outfalls.
Metals benchmarks are calculated to mimic acute water quality standards and with the guidance of
DWR. NC DWR follows established federal procedures for calculating acute standards when developing
the benchmarks. Just like the acute standards, metals benchmarks normally reflect one half of the
calculated Final Acute Value (the "1/2 FAV"). In most cases, translation into total recoverable values is
based on an assumed hardness of 25 mg/L and a total suspended solids (TSS) concentration of 10 mg/L.
Acute standards protect aquatic life from negative impacts of short-term exposure to higher levels of
chemicals where the discharge enters a waterbody. The Stormwater Permitting Program applies this
approach because of the ephemeral nature of rainfall events.
The Division may evaluate results to determine if a smaller suite of parameters for some outfalls is
adequate to characterize potential pollution or BMP effectiveness. For example, one or more metals or
other parameters may serve as an adequate tracer for the presence of ash pollution during disturbance or
ash removal in specific drainage areas at this site. For parameters that do not have a stormwater
benchmark, the Division may develop a benchmark value if appropriate toxicity data become available
or if rising trends in concentrations suggest a persistent source.
A summary of the benchmarks in the draft permit, and their basis, is below:
Parameter Benchmark Basis
Total Suspended 100 mg/L National Urban Runoff Program(NURP) Study, 1983
Solids TSS
H 6 s.u. —9 s.u. NC Water Quality Standard(Range)
Non-Polar Oil & Review of other state's daily maximum benchmark
Grease 15 mg/L concentration for this more targeted O&G;NC WQS that
EPA Method 1664 does not allow oil sheen in waters
(SGT-HEM
BOD 30 mg/L BPJ; Based on Secondary Treatment Regulation(40 CFR
133.03
COD 120 mg/L BPJ; Generally found at levels 4x BOD5 in domestic
wastewaters
Oil & Grease 30 mg/L BPJ, Based on wastewater permit limits.
Copper Total 10 /L Acute Aquatic Criterion, '/2 FAV
Lead Total 75 /L Acute Aquatic Criterion, '/z FAV
Zinc Total 126 /L Acute Aquatic Criterion, '/2 FAV
Stormwater Pollution Prevention Plan: The proposed permit conditions reflect the EPA and NC's
pollution prevention approach to stormwater permitting. The Division's maintains that implementation
of Best Management Practices (BMPs) and traditional stormwater management practices that control the
source of pollutants meets the definition of Best Available Technology (BAT) and Best Conventional
Pollutant Control Technology(BCT). The permit conditions are not numeric effluent limitations but are
designed to be flexible requirements for implementing site-specific plans to minimize and control
pollutants in stormwater discharges associated with the industrial activity. Title 40 Code of Federal
Regulations (CFR) §122.44(k)(2) authorizes the use of BMPs in lieu of numeric effluent limitations in
Page 5 of 7

NPDES permits when the agency finds numeric effluent limitations to be infeasible. The agency may
also impose BMP requirements which are "reasonably necessary" to carry out the purposes of the Act
under the authority of 40 CFR 122.44(k)(3). The conditions proposed in this draft permit are included
under the authority of both of these regulatory provisions. In essence, the pollution prevention and BMP
requirements operate as limitations on effluent discharges that reflect the application of BAT/BCT.
Flexibility in Tier Responses: Tier Two actions provide an opportunity for the permittee to propose an
alternative monitoring plan for approval by the Region:
• 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.
• If pursuing the alternative above after two consecutive exceedances, the permittee may propose
an alternative monitoring plan for approval by the Regional Engineer.
The permit therefore allows the permittee to petition the Regional Office for monitoring changes sooner
than Tier Three (upon any four benchmark exceedances) and gives guidance on one option to take. For
example, the permittee may request that mercury only be monitored semi-annually under the tiers, or
that only parameters over the benchmark be monitored more frequently. In this way, changes to the
monitoring scheme for any outfall could be handled outside of a permit modification.
Other Proposed Requirements:
• It is standard for Stormwater Pollution Prevention Plan(SWPPP)requirements to include an
annual certification that stormwater outfalls have been evaluated for the presence of non-
stormwater discharges, and if any are identified, how those discharges are permitted or otherwise
authorized.
• Requirement to submit a request for permit modification if the facility identifies or creates any
new outfalls, removes outfalls, or alters any drainage area that changes potential pollutants.
• The Division expects the permittee to apply best professional judgment and consider the safety
of its personnel in fulfilling sampling obligations under the permit.
• Federal regulations require electronic submittal of all discharge monitoring reports (DMRs). If a
state does not establish a system to receive such submittals, then permittees must submit DMRs
electronically to the EPA.
• Quarterly QualitativeNisual Monitoring to assure regular observation of outfalls throughout
year.
Section 4. Changes from previous permit to draft:
• Regulatory citations added
• Monitoring increased from semi-annually to quarterly for all parameters (qualitative and
quantitative)
• "No discharge" clarifications made
• Feasibility study requirement removed per updated stormwater program requirements
• Annual online SWPPP certification requirement removed per updated stormwater program
requirements
• eDMR requirement updated
• Boilerplate language moved into body of the permit; boilerplate no longer attached
Page 6 of 7

• Outfall-specific monitoring implemented to reflect industrial activity and potential pollutants
specific to each discharge area
• Monitoring for BOD, oil & grease, total copper, total lead, and total zinc added to outfalls
SW002, SW003, SW004, SW005, SW006, and SWO07 due to materials stored in the drainage
areas (per information provided by permittee)
• Monitoring for total hardness added for outfalls where monitoring for hardness dependent metals
is required
• Benchmarks updated per guidance from DWR Standards group
Section 5. Changes from draft to final:
• None
Section 6. Discussions with the Facility and Regional Office:
• Initial contact with facility: 5/18/2023 (renewal application had not been received; followed up
6/16/23, 8/2/23, 9/27/23, 10/5/23 11/28/23, 1/9/24, 2/14/24)
• Initial contact with Regional Office: 4/8/2024
• Draft sent to CO peer review: N/A

Inspection Date: 04/11/2024 Inspection Type:Compliance Evaluation Reason for Visit: Routine
Inspection Summary:
Kathryn Peterson inspected DyStar on April 11, 2024 at 10 AM. This facility was covered under NCG000161, but it expired in
2021 and a renewal was never requested.Charlie Stroman III is the EHS manager of the facility and provided the SWPPP
and showed outfalls to Kathryn. Mr. Stroman is currently working with Briana Young to get the facility's permit renewed.
The facility is in compliance, but all SWPPP components including analytical, qualitative, and illicit discharge evaluations
should be easily accessible.The SWPPP should be updated every year rather than every five years. The facility should also
ensure to submit a renewal request 180 days before the next pemrit expires.

Brianna,
a. Confirming that the circled area discharges to:
b. These areas do not drain to any stormwater outfalls. .
c. The storage and/or industrial activity occurring in these areas,
d. Everything you have circle in yellow(bullet point below) inside industrial water, all drains to
1. two 90-thousand-gallon spill prevention basin tanks SPCC's.
2. These SPCC's tanks drain directly to the 80-thousan gallon equalization tank(EQ), and this where all the plant
industrial water is aerated and mixed .
3. The EQ drains to our WWTP, where it is processed and sent to our million-gallon City Pond.
4. The City Pond is continued aerated, mixed and discharge to the City of Charlotte outlet.
• warehouse drains,
• resin plant drains to grease pit,
• scrubber and urea areas,
• drum storage drains,
• truck loading and unloading areas,
• maintenance shop,
• everything in glyoxal area have been dismantled and no longer available also drains to WWTP
• above ground storage tank farm areas:
o plus, hazardous AGST have secondary containment,
I did share some picture to help with where the industrial waters drain to.
Please let me know if you have any or need anything else.

Dear Brianna,
Please find additional information requested for the facility stormwater application.
I hope this information is what you need to satisfy the completion of the application.
• Updated site map (the one provided is cut off)
Attached-drainage map.
• Description of chemicals stored onsite.
Numerous raw chemicals are used in the production process and are stored in drums,totes,and in bulk.These raw materials are
stored either inside the facility warehouse or outside in aboveground storage tanks. Raw materials are received at loading docks by
tanker truck. The final products are stored in bulk aboveground storage tanks in facility warehouses and are shipped off-site via
tanker truck, drums,or totes.The main facility is surrounded by asphalt pavement,grassed areas,and a perimeter fence.
Drainage from the facility flows generally to the southeast.Stormwater flows over paved and grassy portions of the site to storm
drainage piping and ditches that flow southeast to Paw Creek,which discharges into Lake Wylie.
Oil storage at the facility consists primarily of two No. 2 fuel oil tanks,ten oil based chemical storage tanks, one oil reservoir,one
1,100-gallon diesel tank,six transformers,waste oil drums and miscellaneous lubricating oil drums.
• Description of industrial activity in each drainage area.
FACILITY DRAINAGE
9

The facility has implemented a spill containment system at the Charlotte facility. The major components of the system are two
90,000-gallon basins that receive all drainage, including storm water runoff, from the tank farm area and building areas. This
system also incorporates a flow buffer basin during significant storm events. Storm water from non-process areas is not routed
to the spill containment basins. Runoff from these areas travel via eight drainage areas.
Drainage Area 01, at the east side of the developed property, drains to Outfall 01, the end of a concrete pipe. Since this drainage
area consists primarily of office area, this outfall is not associated with industrial activity. Drainage Areas 02, 03, 04, 05, 06, and
07 are located at the south side of the developed property. These drainage areas drain to the ends of concrete storm drainage
pipes designated as
Outfalls 02, 03, 04, 05, 06 and 07, respectively. Potential pollutant sources in these areas include dumpster runoff, scrap
metal runoff, pallet runoff, and runoff from drum, tote, and tanker storage areas. Drainage Area 08, consisting of one catch
basin located at the northern side of the building drains to Outfall 08. Potential pollutants sources in this drainage area are
limited to pollutants from nearby roof drains only. Drainage from the demolished glyoxal pr000ss area, the fire pump station,
and the Waste Treatment area do not drain via a designated outfall. Flow from these areas drain via sheet flow.
Storm water flows over paved and grassy portions of the site to storm drainage piping and ditches that flow southeast to Paw
Creek. Paw Creek flows in a southern direction and drains to Lake Wylie.
Wastewater discharges are generated from the following sources:domestic wastewater; non-contact cooling water from
single pass cooling; boiler blowdown;storm water runoff from tank farm; laboratory wastewater from sinks; process
wastewater from the cleanup of reactor vessels; air pollution control water; pump sealant water;and equipment and facility
wash down water. The preceding waste streams are collected in the 80,000-gallon equalization basin and then fed to the
pretreatment system. After pretreatment, all wastewater is discharged to the sanitary sewer through Pipe 001. Pipe 001 is
the intake to or the outlet from the approved primary measuring device.
The facility has provided adequate discharge and drainage controls through the implementation of this Plan. Bulk storage
containers are provided with secondary containment structures to contain any potential spills and all oil storage drums greater
than 55 gallons are placed upon spill containment pallets.Absorbent materials from spill kits and granular absorbent are available
to control potential discharges outside of secondary containment structures.
The facility has implemented a spill containment system at the Charlotte facility. This system is designed to prevent spills of an
emergency nature occurring in the tank farm where bulk oil and hazardous materials are stored. This system is designed to
prevent spilled materials from flowing off-site and possibly causing an adverse environmental or public health impact. The
major components of the system are two 90,000-gallon basins that receive all drainage, including storm water runoff, from the
tank farm area and building areas. This system is equipped with a bypass valve which always remains closed. In the event of
significant rain events, storm water may be routed to a flow buffer basin.

Restraining Drainage from Dikes Storage Areas
The major components of the containment system are two 90,000-gallon basins that receive all drainage,
including stormwater runoff, from the tank farm area and building areas. This system is equipped with a
bypass valve which always remains closed. In the event of significant rain events, stormwater may be routed
to a flow buffer basin. The spill containment system operation is the responsibility of the Plant Environmental
staff on the first shift, Monday through Friday. Lead Operators are responsible for operation of the spill
containment system on the second and third shifts, Monday through Friday, and on weekends and
holidays. The Plant Environmental staff communicates with the shift supervisors on the spill containment
system operation daily (Monday-Friday), during emergencies, and on weekends when possible.
Secondary Containment
Secondary containment is provided for each bulk storage container as defined in 112.2. Secondary
containment calculations are presented in Appendix G. A description of secondary containment is
provided as follows:
• The two No. 2 Fuel Oil tanks are equipped with a concrete dike.
11

• Tanks 300-1, 300-29, 300-38, 300-63, 300-64, 300-65 and 300-66 are equipped with a concrete
dike.
• The diesel fuel storage tank is double walled.
• Tanks 300-7 and 300-8 are located within an area which drains to the (2) 90,000-gallon spill
containment basins.
• The outside lubricating oil drums are in areas with concrete curbing.
• The lubricating oil drums located in the warehouse do not have secondary containment, but spills
drain directly to the Wastewater Treatment plant above ground open head tanks, which are checked
daily and only released after visual and if necessary analytical inspections are done.
An explanation of any operational or significant changes since the last permit was issued.
No operational or significant changes since the last permit was issued.
Summary of Best Management Practices
The DyStar Carolina Chemical facility is engineered to contain stormwater from process areas by directing flow
to two 90,000-gallon SPCC basins. Water can be released from these basins in two ways. Stormwater can be
directed to the wastewater treatment plant located on-site or a flow buffer basin located adjacent to the
WWTP. In addition, several above ground storage tanks are diked and equipped with an eighteen-inch
bentonite liner and a 6" French drain system. Drainage from all tank storage areas is routed to the SPCC
basins. Other best management practices at the facility include the storage of full and empty drums in
designated areas inside the facility, the regular pickup of trash, and the removal of manifested
waste. Furthermore, the facility stores hazardous waste in three locations equipped with secondary
containment. The primary location is an engineered designed covered hazardous waste pad and each of the
two labs on site has a satellite hazardous waste area which is also equipped with secondary containments.
I may have some more information to add on Monday about drainage area.
I hope this information is what you need to satisfy the application and if you need additional information please advise?
Thank you.

Dear Brianna,
Please find additional information requested for the facility stormwater application.
I hope this information is what you need to satisfy the completion of the application.
• Updated site map (the one provided is cut off)
Attached- drainage map.
• Description of chemicals stored onsite.
Numerous raw chemicals are used in the production process and are stored in drums, totes, and in bulk. These raw materials are
stored either inside the facility warehouse or outside in aboveground storage tanks. Raw materials are received at loading docks by
tanker truck. The final products are stored in bulk aboveground storage tanks in facility warehouses and are shipped off -site via
tanker truck, drums, or totes. The main facility is surrounded by asphalt pavement, grassed areas, and a perimeter fence.

Drainage from the facility flows generally to the southeast. Stormwater flows over paved and grassy portions of the site to storm
drainage piping and ditches that flow southeast to Paw Creek, which discharges into Lake Wylie.
Oil storage at the facility consists primarily of two No. 2 fuel oil tanks, ten oil based chemical storage tanks, one oil reservoir, one
1,100-gallon diesel tank, six transformers, waste oil drums and miscellaneous lubricating oil drums.
• Description of industrial activity in each drainage area.
FACILITY DRAINAGE
The facility has implemented a spill containment system at the Charlotte facility. The major components of the system are two
90,000-gallon basins that receive all drainage, including storm water runoff, from the tank farm area and building areas. This
system also incorporates a flow buffer basin during significant storm events. Storm water from non -process areas is not routed
to the spill containment basins. Runoff from these areas travel via eight drainage areas.
Drainage Area 01, at the east side of the developed property, drains to Outfall 01, the end of a concrete pipe. Since this drainage
area consists primarily of office area, this outfall is not associated with industrial activity. Drainage Areas 02, 03, 04, 05, 06, and
07 are located at the south side of the developed property. These drainage areas drain to the ends of concrete storm drainage
pipes designated as
Outfalls 02, 03, 04, 05, 06 and 07, respectively. Potential pollutant sources in these areas include dumpster runoff, scrap
metal runoff, pallet runoff, and runoff from drum, tote, and tanker storage areas. Drainage Area 08, consisting of one catch
basin located at the northern side of the building drains to Outfall 08. Potential pollutants sources in this drainage area are
limited to pollutants from nearby roof drains only. Drainage from the demolished glyoxal prooess area, the fire pump station,
and the Waste Treatment area do not drain via a designated outfall. Flow from these areas drain via sheet flow.
Storm water flows over paved and grassy portions of the site to storm drainage piping and ditches that flow southeast to Paw
Creek. Paw Creek flows in a southern direction and drains to Lake Wylie.
Wastewater discharges are generated from the following sources: domestic wastewater; non -contact cooling water from
single pass cooling; boiler blowdown; storm water runoff from tank farm; laboratory wastewater from sinks; process
wastewater from the cleanup of reactor vessels; air pollution control water; pump sealant water; and equipment and facility
wash down water. The preceding waste streams are collected in the 80,000-gallon equalization basin and then fed to the
pretreatment system. After pretreatment, all wastewater is discharged to the sanitary sewer through Pipe 001. Pipe 001 is
the intake to or the outlet from the approved primary measuring device.
The facility has provided adequate discharge and drainage controls through the implementation of this Plan. Bulk storage
containers are provided with secondary containment structures to contain any potential spills and all oil storage drums greater
than 55 gallons are placed upon spill containment pallets. Absorbent materials from spill kits and granular absorbent are available
to control potential discharges outside of secondary containment structures.
The facility has implemented a spill containment system at the Charlotte facility. This system is designed to prevent spills of an
emergency nature occurring in the tank farm where bulk oil and hazardous materials are stored. This system is designed to
prevent spilled materials from flowing off -site and possibly causing an adverse environmental or public health impact. The
major components of the system are two 90,000-gallon basins that receive all drainage, including storm water runoff, from the
tank farm area and building areas. This system is equipped with a bypass valve which always remains closed. In the event of
significant rain events, storm water may be routed to a flow buffer basin.

Restraining Drainage from Dikes Storage Areas
The major components of the containment system are two 90,000-gallon basins that receive all drainage,
including stormwater runoff, from the tank farm area and building areas. This system is equipped with a
bypass valve which always remains closed. In the event of significant rain events, stormwater may be routed

Summary of Best Management Practices
The DyStar Carolina Chemical facility is engineered to contain stormwater from process areas by directing flow
to two 90,000-gallon SPCC basins. Water can be released from these basins in two ways. Stormwater can be
directed to the wastewater treatment plant located on -site or a flow buffer basin located adjacent to the
WWTP. In addition, several above ground storage tanks are diked and equipped with an eighteen -inch
bentonite liner and a 6" French drain system. Drainage from all tank storage areas is routed to the SPCC
basins. Other best management practices at the facility include the storage of full and empty drums in
designated areas inside the facility, the regular pickup of trash, and the removal of manifested
waste. Furthermore, the facility stores hazardous waste in three locations equipped with secondary
containment. The primary location is an engineered designed covered hazardous waste pad and each of the
two labs on site has a satellite hazardous waste area which is also equipped with secondary containments.
I may have some more information to add on Monday about drainage area.
I hope this information is what you need to satisfy the application and if you need additional information please advise?
Thank you.

Dear Brianna,
Please find additional information requested for the facility stormwater application.
I hope this information is what you need to satisfy the completion of the application.
• Updated site map (the one provided is cut off)
Attached- drainage map.
• Description of chemicals stored onsite.
Numerous raw chemicals are used in the production process and are stored in drums, totes, and in bulk. These raw materials are
stored either inside the facility warehouse or outside in aboveground storage tanks. Raw materials are received at loading docks by
tanker truck. The final products are stored in bulk aboveground storage tanks in facility warehouses and are shipped off -site via
tanker truck, drums, or totes. The main facility is surrounded by asphalt pavement, grassed areas, and a perimeter fence.
Drainage from the facility flows generally to the southeast. Stormwater flows over paved and grassy portions of the site to storm
drainage piping and ditches that flow southeast to Paw Creek, which discharges into Lake Wylie.
Oil storage at the facility consists primarily of two No. 2 fuel oil tanks, ten oil based chemical storage tanks, one oil reservoir, one
1,100-gallon diesel tank, six transformers, waste oil drums and miscellaneous lubricating oil drums.
• Description of industrial activity in each drainage area.
FACILITY DRAINAGE
The facility has implemented a spill containment system at the Charlotte facility. The major components of the system are two
90,000-gallon basins that receive all drainage, including storm water runoff, from the tank farm area and building areas. This
system also incorporates a flow buffer basin during significant storm events. Storm water from non -process areas is not routed
to the spill containment basins. Runoff from these areas travel via eight drainage areas.
Drainage Area 01, at the east side of the developed property, drains to Outfall 01, the end of a concrete pipe. Since this drainage
area consists primarily of office area, this outfall is not associated with industrial activity. Drainage Areas 02, 03, 04, 05, 06, and
07 are located at the south side of the developed property. These drainage areas drain to the ends of concrete storm drainage
pipes designated as
Outfalls 02, 03, 04, 05, 06 and 07, respectively. Potential pollutant sources in these areas include dumpster runoff, scrap
metal runoff, pallet runoff, and runoff from drum, tote, and tanker storage areas. Drainage Area 08, consisting of one catch
basin located at the northern side of the building drains to Outfall 08. Potential pollutants sources in this drainage area are
limited to pollutants from nearby roof drains only. Drainage from the demolished glyoxal prooess area, the fire pump station,
and the Waste Treatment area do not drain via a designated outfall. Flow from these areas drain via sheet flow.

Storm water flows over paved and grassy portions of the site to storm drainage piping and ditches that flow southeast to Paw
Creek. Paw Creek flows in a southern direction and drains to Lake Wylie.
Wastewater discharges are generated from the following sources: domestic wastewater; non -contact cooling water from
single pass cooling; boiler blowdown; storm water runoff from tank farm; laboratory wastewater from sinks; process
wastewater from the cleanup of reactor vessels; air pollution control water; pump sealant water; and equipment and facility
wash down water. The preceding waste streams are collected in the 80,000-gallon equalization basin and then fed to the
pretreatment system. After pretreatment, all wastewater is discharged to the sanitary sewer through Pipe 001. Pipe 001 is
the intake to or the outlet from the approved primary measuring device.
The facility has provided adequate discharge and drainage controls through the implementation of this Plan. Bulk storage
containers are provided with secondary containment structures to contain any potential spills and all oil storage drums greater
than 55 gallons are placed upon spill containment pallets. Absorbent materials from spill kits and granular absorbent are available
to control potential discharges outside of secondary containment structures.
The facility has implemented a spill containment system at the Charlotte facility. This system is designed to prevent spills of an
emergency nature occurring in the tank farm where bulk oil and hazardous materials are stored. This system is designed to
prevent spilled materials from flowing off -site and possibly causing an adverse environmental or public health impact. The
major components of the system are two 90,000-gallon basins that receive all drainage, including storm water runoff, from the
tank farm area and building areas. This system is equipped with a bypass valve which always remains closed. In the event of
significant rain events, storm water may be routed to a flow buffer basin.

All stormwater runoff not diverted to the spill containment system travel off -site from eight drainage areas. Drainage
Area 01, at the east side of the developed property, drains to Outfall 01, the end of a concrete pipe. Because this
odrainage
area consists primarily of office area, this outfall is not associated with industrial activity. Drainage Areas 02,
N
03, 04, 05, 06,and 07 are located at the south side of the developed property. These
j9
drainage areas discharge via concrete storm drainage pipes, designated as
Outfalls 02, 03, 04, 05, 06 and 07, respectively. Potential pollutant sources in these areas include dumpster runoff,

Notes:
The Qualifiers in this report are defined as follows:
N/A indicates that spike recovery limits do not apply when sample concentration exceeds spike cone. by a factor of 4 or more or %RPD not applicable.
^ The Relative Percent Difference (RPD) obtained from the sample duplicate (DUP) is evaluated against the acceptance criteria when the sample is greater than
five times (5X) the contract required detection limit (RL). In cases where the duplicate value is less than 5X the RL, a control limit of +/- the RL is used to
evaluate the DUP result.
* Indicates that a Quality Control parameter was not within specifications.
For PS, PSD, and SDILT results, the values listed are the measured amounts, not final concentrations.
Where the analytical method has been performed under NELAP certification, the analysis has met all of the
requirements of the NELAC standard unless qualified on the QC Summary.

Good afternoon,
I am following up on my previous correspondence regarding stormwater permit NCS000161. The current permit expired
October 31, 2021 with no renewal application submitted before expiration. Operating a treatment facility, discharging
wastewater, or discharging specific types of stormwater to waters of the State without valid coverage under an NPDES

NPDES permit NCS000161
Mecklenburg County
Dear Permittee:
Per the terms of your NPDES permit found in Part III, Section A. 8., you are required to provide
information to the Division when requested. Per the terms of your NPDES permit found in Part
III, Section B. I., you are required to apply for permit renewal no later than 180 days prior to the
expiration date. On May 18, 2023, the Division sent an additional information request as the
permit renewal application for stormwater permit NCS000161 had not yet been submitted. The
current permit expired on October 31, 2021 therefore a permit renewal application was due by
May 4, 2021. The Division followed up on this request for a permit renewal application on June
16, 2023 and August 2, 2023.
Our records indicate that as of the date of this letter, the permit renewal application has not been
received. Failure to provide requested information to the Division is a violation of the terms of
your permit, subjecting you to a possible assessment of civil penalties.
The following permit condition violations are noted:
Part III, Section A. 8. Duty to Provide Information
The permittee shall furnish to the Director, within a reasonable time, any information which the
Director may request to determine whether cause exists for modifying, revoking and reissuing, or
terminating the permit issued pursuant to this individual permit or to determine compliance with
this individual permit. The permittee shall also furnish to the Director upon request, copies of
records required to be kept by this individual permit.
Based upon the above facts, I conclude as a matter of law that the DyStar LP violated or failed to
act in accordance with the requirements of NPDES Permit NCS000161 and G.S. 143-215.1 (b). A
civil penalty of not more than $25,000.00 per violation may be assessed against a person

requested information within ten (10) days of receipt of this notice.
Please ensure that the requested information is sent to the Division. A review of your response
will be considered and you will be notified of any civil penalties that may be assessed regarding
