Dear Mr. Dowden:
Enclosed are one original and two copies of a permit application and supporting documents for
renewal of the subject NPDES permit for Clariant Corporation's Mount Holly East facility. It is
my understanding that no fee is required since the documents being submitted are for renewal
of the permit.
Background
Clariant's Mount Holly East facility is a former chemical production site in Mecklenburg County
near Mount Holly, North Carolina. Clariant no longer performs any chemical manufacturing at
this facility, but leases portions of the facility to outside tenants. Wastewater generated at the
facility is treated at an on-site wastewater treatment plant (WWTP) operated by Clariant. The
treated wastewaters are discharged to the Catawba River under NPDES Permit Number
NC0004375.
This facility produced dyes and specialty chemicals from 1936 until 2005, at which time it
ceased all organic chemical manufacturing and processing. Originally permitted under the
NPDES program in the Organic Chemicals, Plastics and Synthetic Fibers (OCPSF) industrial
category, the facility was also permitted as a Centralized Waste Treatment facility(CWT) from
2003 until 2012 when all CWT operations ceased. Based on current operations, the facility is
now permitted only under non-categorical guidelines.
Clariant modified its WWTP in 2013 for biological treatment of contaminated groundwater,
stormwater, and facility sanitary wastewater by converting one of its 500,000-gallon secondary
clarifier tanks into an activated sludge tank and mothballing the larger in-ground activated
sludge basin historically used by the WWTP. The treatment performance of the modified

CLARIANT
WWTP continues to be excellent as evidenced by the 2021-2022 effluent data included with the
permit renewal submittal.
Clariant's WWTP currently treats sanitary wastewater generated on-site by tenant operations,
intermittent non-contact cooling water generated from one site tenant, and stormwater from
portions of the site including leachate from an on-site permitted sludge landfill that drains to the
WWTP. Contaminated groundwater pumped from site remediation wells was historically
treated in the on-site WWTP. However, in late 2018, with NCDEQ's concurrence, the site
groundwater extraction system was deactivated. Although contaminated groundwater is not
currently extracted for treatment, Clariant retains the capability to activate the groundwater
system for treatment and discharge, if required in the future.
Tenants at the site discharge only sanitary wastewater, with one exception:
■ Clean Energy operates two generators using renewable natural gas (RNG)for
electricity production and sale to the Duke Energy power grid system. Non-contact
cooling water is used in the heat exchangers by this tenant, which is discharged to a
cooling pond. Occasionally some quantity of this cooled water from the pond is sent
to the WWTP for treatment and discharge. No chemicals are added to the pond or the
non-contact loop of the system. This is a non-categorical operation.
All sanitary and intermittent non-contact cooling water is treated at the on-site WWTP before
discharge.
Application Package
The application package being submitted for the permit renewal and modification includes the
following documents:
• EPA Form 1 — General Information
• EPA Form 2C NPDES — Existing Manufacturing, Commercial, Mining, and
Silviculture Operations
• Application Support Document
With this permit renewal application, Clariant is also requesting the following permit changes.
Information supporting these requests is presented in the enclosed Application Support
Document.
• Elimination of the requirement to monitor effluent for Oil &Grease, based on the absence
of sources and the recent history of low and mostly non-detect monitoring results.
• Elimination of the requirement to sample and characterize influent wastewater sources,
based on the low strength and predictability of these wastewater sources.
Pane of

CLARIANT
I appreciate the Division's cooperation and assistance with renewal and modification of our
NPDES permit. I would be glad to meet with you to discuss the application documents and our
plans for the Clariant's Mount Holly East facility if you feel this would be helpful. Please feel
free to call either Ned Fiss with Fiss Environmental Solutions at (704) 374-540o, or me at (704)
331-7722, if you have any questions or need additional information.
Sincerely,

The Clariant Corporation operates an industrial park at the site of its former integrated organic chemicals
manufacturing facility in Mount Holly NC. The facility was formerly a specialty chemical and dye manufacturing
site since 1937,but in mid 2005 the production units were shut down. The facility also previously operated as a
centralized waste treatment(CWT)facility but has since ceased CWT operations and does not accept 3rd party
0o wastes for treatment at its wastewater treatment plant(WWTP). Since there are no CWT operations on-site,the
only treated wastewaters include 1)Sanitary wastewater from site tenants 2)Leachate from an on-site landfill and
stormwater from the facility 3)Intermittent non-contact cooling water from one tenant operation 4)Filter backwash
z and fire suppression maintenance system. The facility also has a groundwater pump and treat system that is
currently deactivated with NCDEQ approval on a trial basis since late 2018,but could potentially be reactivated in
the future if needed. These treated wastewaters are discharged to the Catawba River under a NPDES permit issued

SECTION 1.0
BACKGROUND
1.1 GENERAL
The Clariant Mt. Holly East facility is a former chemical production site near Mount Holly,
North Carolina that is owned by Clariant Corporation (Figure 1- Site Location Map). The
facility no longer performs any chemical manufacturing, but leases portions of the facility to
various tenants. Wastewater from the facility is treated at an on-site wastewater treatment plant
(WWTP)operated by Clariant and the treated wastewaters are discharged to the Catawba River
under NPDES Permit No. NC0004375. This permit was issued by the North Carolina
Department of Environmental Quality (NCDEQ), Division of Water Resources (DWR). The
current NPDES permit became effective on January 1, 2018 and expires on December 31, 2022.
During the 2018 permit renewal, modifications were issued by NCDEQ to include 1) Waiving
the river staging requirements, 2) prescribing technology-based limits for conventional
parameters (BOD5 &TSS)and 3) assigning summer and winter Total Nitrogen(TN) loads and
annual Total Phosphorus(TP) loads in the renewed NPDES permit.
This Application Support Document has been prepared by FISS Environmental Solutions,Inc.
(FISS). The purpose of this document is to present information required for renewal of the
Clariant-Mt. Holly NPDES permit in accordance with NCDEQ regulations and US EPA effluent
guidelines for non-categorical wastewaters.
The Clariant-Mt. Holly East facility was formerly a specialty chemical and dye manufacturing
site from 1936 until mid-2005. Prior to 2005,the primary products produced by the Clariant-Mt.
Holly East facility were sulfur-based dyes and specialty organic chemicals. The wastewater
discharge was subject to discharge limitations in the US EPA categorical standards for Organic
Chemicals, Plastics and Synthetic Fibers (OCPSF), 40 CFR Part 415. However, all organic
chemical manufacturing and processing ceased in 2005. According to the OCPSF guidelines and
confirmed by Jan Matuszko at the US EPA, OCPSF regulations apply only to process
wastewater discharges resulting from the manufacture of OCPSF products, and as such,these

regulations no longer apply to the Clariant facility since all OCPSF production has been
discontinued.
The facility was also authorized to operate as a centralized waste treatment(CWT) facility by
NCDEQ(formerly NCDENR) in 2003 under the US EPA categorical standards for Centralized
Waste Treatment,40 CFR Part 437. However, all CWT operations at the Clariant facility were
terminated in 2012 and the facility has not accepted any 3rd party wastes since that time for
treatment. Residual WWTP sludges contained in on-site surface impoundments were removed,
dewatered and disposed at the on-site landfill during 2012 -2013. Filtrate wastewater from the
sludge dewatering operations during this period was discharged to the on-site WWTP for
treatment and subsequent NPDES discharge. The facility currently treats only the wastewaters
generated on-site by the various tenants. The treated wastewaters include:
1. Impacted stormwater from the facility along with leachate from an on-site landfill cell;
2. Non-contact cooling wastewater and domestic wastewater from current on-site, non-
OCPSF operations; and
3. Filter backwash and Fire tank water from maintenance of the facility fire suppression
system.
The Clariant Mt. Holly East site is a former Superfund site, which was certified for Brownfield
redevelopment by the State of North Carolina in 2012. Currently, eight(8)tenants have
operations at the facility, of which only one (1)operation generates the non-contact cooling
wastewaters for treatment in the on-site WWTP.
Because of soil and groundwater impacts from historical OCPSF operations,the facility was
previously included on the National Priorities List(NPL) due to organic contaminants contained
in soil and groundwater at the site. Impacted groundwater from the site was extracted and
treated through the on-site WWTP. However, in late 2018, the NCDEQ agreed to Clariant's
request to deactivate the site groundwater extraction system on a trial basis due to declining
contaminant concentration trends in contaminated groundwater. Therefore,there is no
contaminated groundwater currently being treated in the on-site WWTP. If required,the
Clariant NPDES Permit 3 08/23/22

groundwater extraction system can be reactivated in the future with the contaminated
groundwater treated through the on-site WWTP before discharge.
All tenant operations generate only sanitary wastewater with the exception of intermittent non-
contact cooling water from one(1)tenant as listed below. All sanitary wastewater and
intermittent non-contact cooling water are treated in the on-site WWTP: Table 1-1 lists the
current tenants and their description.
• Clean Energy—A non-categorical operation that generates electricity using renewable
natural gas. This tenant uses filtered river water for non-contact cooling through heat
exchangers. The non-contact cooling water is discharged to an on-site cooling pond.
Occasionally the cooled water from this pond is discharged to the on-site WWTP.

1.2 EXISTING WASTEWATER SYSTEM
The Clariant Mt. Holly East site operates a 2.5 MGD WWTP consisting of the following
components:
• Three stormwater equalization basins that can hold wastewater(ZO3B,Z-26&Z-
25);
• One activated sludge aeration basin with mechanical mixing& diffused aeration.
• One secondary clarifier.
• Two polishing ponds.
• Staged discharge facility including effluent holding basin and post aeration.
• Two sludge holding tanks; and
• Two sludge dewatering belt presses.
The Clariant Mt. Holly East site operates with two separate sewer systems, an alkaline sewer and
an acid sewer(named based on former OCPSF operations). Both carry sanitary wastewater and
impacted stormwater to the on-site WWTP for treatment. Because of the reduced wastewater
flows due to termination of the 3rd party wastewaters, the facility modified its wastewater
treatment system in 2012 to optimize its wastewater treatment processes. These included
Clariant NPDES Permit 5 08/23/22
Supporting Documentation

conversion of one of the secondary clarifiers to an activated sludge tank and discontinuation of
the operations of the primary clarifiers and former 4.5 MG equalization/aeration basin.
The acid sewer is a gravity system that terminates in a lift station at the WWTP. A transfer
pump is used to pump the lift station wastewater to the alkaline lift station. The acid sewer
system has a capacity of 500,000 gallons per day. There are currently no processes at the site
that produce acidic wastewater requiring neutralization.
The alkaline sewer is a gravity system that terminates in a lift station near the current WWTP.
The lift station pumps contaminated stormwater(which includes landfill leachate), non-contact
cooling water, fire system maintenance water and sanitary wastewater to the current activated
sludge tank(previously one of the secondary clarifiers). Groundwater from the pump and treat
system can also be pumped to the alkaline pump station if required. The site groundwater
extraction system is currently deactivated with NCDEQ approval on a trial basis due to declining
contaminant concentration trends in impacted groundwater, but could potentially be reactivated
in the future if needed. Any stormwater or wastewater flows in excess of the capacity of the lift
station can be diverted into a storage impoundment. The alkaline sewer system has a capacity of
4,500,000 gallons per day.
The activated sludge tank and the remaining secondary clarifier have a volume of 0.5 MG each
and are designed to handle up to 2.5 MGD of flows. The activated sludge aeration basin is
equipped with diffused aeration and mixers that maintain a homogeneous mixture of sludge and
water. A centrifugal blower provides air to the diffused aeration system for transfer of dissolved
oxygen for the mixed liquor bacterial population as needed. The mixed liquor flows by gravity
from the aeration basin to the secondary clarifier. Settled biological sludge from the clarifier is
returned to the aeration basin as Return Activated Sludge (RAS). Waste activated sludge is
pumped to the existing sludge holding tanks and belt presses for dewatering and landfilling.
Treated effluent exiting the secondary clarifier flows to a first polishing pond,then a canal
paralleling the WWTP, which then discharges to a second polishing pond. This second pond has
an effluent lift station and an exit valve that can shut-off flow to the river. The gravity flow
Clariant NPDES Permit 6 08/23/22
Supporting Documentation

exiting from the pond passes through a flow measurement flume prior to entering another canal
that conveys the water to a submerged discharge point in the Catawba River.
The effluent lift station can deliver the entire flow of the exiting effluent to a 360 MG effluent
holding basin for storage and re-treatment through the WWTP. If any of the permitted effluent
parameters are expected to be impacted by a process upset or spill in the complex,the WWTP
effluent is pumped into the effluent holding basin. Water that is diverted into the effluent
holding basin is eventually released back to the WWTP and re-treated through the activated
sludge system prior to discharge.
13 FACILITY CHANGES
Clariant has no plans to modify any of the current on-site WWTP processes or components since
the wastewater they receive is compatible with existing WWTP design. Whie additional tenants
may be included in the future,Clariant does not intend for these future tenants to generate
wastewater apart from sanitary purposes. This application does not include provisions for
potential expansion of the WWTP. A brief discussion of the current site utilization is presented
below.
1.3.1 Shutdown of Dye and Specialty Chemical Manufacturing
Clariant no longer operates the textile chemical and dyestuff plant within the complex.
This plant was shut down in October 2002. All specialty chemical manufacturing and
processing was ceased in mid-2005. Both operations were subsequently cleaned and
mothballed.
1.3.2 Termination of CWT Operations
CWT operations were initiated in 2003 and were terminated in 2012. The site no longer
accepts any 3�d party wastes.
1.3.3 Clean Energy
Clean Energy operates generators for renewable energy electricity production,which is
sold to Duke Energy. The fuel is renewable natural gas(RNG)derived from organic

wastes. Heat exchangers are currently used in the process and generates the requirement
for non-contact cooling water to be sent to a cooling pond. Some portion of the cooled
non-contact water is sent intermittently to the WWTP for treatment. Apart from the non-
contact cooling water and sanitary wastewater from Building 21 and 51,there are
currently no other wastewater contributions from this operation.

times greater than the average daily flow based on average max daily flow of 0.607 MGD and average
daily flow of 0.166 MGD from Table 2-1. This factor was used for projecting the maximum monthly
flows for the various wastewater sources.These flows do not include wastewaters from the groundwater
extraction system,since it is not currently being operated.
2.2.2 Non-Categorical Wastewaters
Clariant continues to treat the following existing non-categorical wastewaters in the on-
site WWTP:
• Sanitary Wastewater(2,000 gpd);
• Filter Plant Backwash (1,000 gpd);
• Stormwater(80,000 gpd)-As discussed above, the Clariant-Mt. Holly East site was
previously included on the NPL due to organic contaminants contained in
groundwater and surface water. These contaminants resulted from historical OCPSF
activities previously performed at the facility. These contaminated stormwaters,
which continue to be treated in the on-site WWTP using biological treatment for
removal of contaminants prior to discharge, are generated from the following areas
on-site:
Clariant NPDES Permit 15 08/23/22
Supporting Documentation

• Landfill Cell 3;
• Production buildings area; and
• Non-process areas.
• Fire Suppression System (14,000 gpd)—The Clariant-Mt. Holly East site has a fire
suppression system that requires daily maintenance by operating the fire pumps for a
set amount of time. This filtered river water, is discharged to the on-site WWTP for
biological treatment prior to discharge.
• Clean Energy Non-Contact Cooling Water(69,000 gpd)—Clean Energy operates
two (2)generators that utilize renewable natural gas to produce electricity that is sold
to the electrical grid. As part of this operation, makeup cooling water is provided
from filtered river water which goes through heat exchangers as part of the cooling
process. The heat transferred water is then sent to a cooling pond as part of a closed
loop system. At certain times, when the pond has reached capacity,the non-contact
cooling water is sent to the WWTP for biological treatment and discharge. There are
no chemicals added to the cooling pond or the nori-contact loop of the heat
exchangers. Clariant does not have a cooling water intake nor does the withdrawal of
river water for cooling use exceed 2 MGD. Therefore,this operation is not covered
by any of the categorical standards in the US EPA Subchapter N Effluent Guidelines
and Standards nor does it meet 40CFR 125.91 Subpart J(Requirements Applicable to
Cooling Water Intake Structures for Existing Facilities).
2.2.3 Influent Waste Characterization
Per Section A (8) of the current NPDES Permit,Clariant is required to conduct analytical
sampling of the individual wastestreams that discharge to the on-site WWTP and include
these results with the application for permit renewal. The Permit specifically states that
the following sources should be sampled:
• Sanitary Wastes
• Contaminated Groundwaters
• Landfill Leachate
• Process area stormwater
• Non-process area stormwater
Clariant NPDES Permit 16 08/23/22
Supporting Documentation

• Flows from each existing tenant operations and
• Filter Plant backwash.
The site wastewater flows are such that it is difficult to segregate some of the sources to the on-
site WWTP. For instance, sanitary wastestreams from site tenants are sent to the alkaline and
acid lift stations where it combines with stormwater flows. There are no separate outfalls for
conveying site process and non-process stormwaters. The groundwater extraction system has
been deactivated and so there are no groundwater flows sent to the WWTP. Apart from
occasional non-contact cooling water flow from the Clean Energy cooling pond, all site tenants
only discharge sanitary wastewaters. The sand filters are operated very sporadically and the
backwash from these filters are essentially filtered river water.
In order to satisfy the requirements of Section A (8), Clariant has conducted analytical sampling
from the following locations:
• Influent wastewater to the alkaline lift station during a dry period (no precipitation)to
characterize site sanitary wastewaters
• Influent wastewater to the alkaline lift station during a wet period (rain event day)to
characterize the contribution of site stormwater
• Landfill leachate
• Clean Energy non-contact cooling water
Although the groundwater extraction system is currently not operational,Clariant is required to
monitor the groundwater per its RCRA permit. Analytical results from the groundwater
monitoring program are included in Appendix C along with the analytical laboratory reports for
the above listed wastestream sources.
The influent waste stream characteristics are low strength and comprise mostly of sanitary,non-
contact cooling and stormwater sources. As such Clariant is requesting that the Section A (8)
requirement for analytical sampling of the individual wastestreams that discharge to the on-site
WWTP be removed from the renewed Permit, since the existing sources and characteristics are
not expected to change significantly.

SECTION 3.0
EFFLUENT GUIDELINES AND STANDARDS
3.1 GENERAL
There have been no changes in facility wastewater flows and characteristics that would affect the
current NPDES effluent limits. As discussed in Section 2.2.1,based on current operations, all
wastewaters being generated at the facility are considered to be non-categorical.
3.2 CONVENTIONAL PARAMETERS
The current permit limits prescribed by NCDEQ for the specific non-categorical discharges are
summarized in Table 3-1. No changes from the current permit are being requested at this time.
Proposed limits for conventional parameters were previously determined based on a final
effluent flow of 1.709 MGD, which is less than the 2.5 MGD hydraulic capacity of the modified
WWTP.

Notes:
(1) Summer TN Load is sum of monthly TN loads for April-October.
(2) Winter TN Load is sum of monthly TN loads for November—March
(3) The Permit lists other parameters that need to be monitored and reported.
However,no limits have been prescribed for those parameters.
Clariant NPDES Permit 18 08/23/22
Supporting Documentation

3.3 NON-CONVENTIONAL PARAMETERS
3.3.1 Oil and Grease
Oil and grease (O&G) is included in the current permit but is requested by Clariant to be
removed since CWT operations have ceased and there are no processes on-site that could
contribute this parameter. The current NPDES permit contains the requirement to
monitor and report the O&G on a monthly basis. Actual Clariant effluent data for O&G
are presented in Appendix A. As shown in the data,only one (1)out of the thirteen(13)
samples collected showed an O&G detection at 1.8 mg/1,with the rest of the samples
below analytical detection limits. Clariant is therefore requesting that all monitoring
requirements for O&G be deleted from the NPDES permit upon renewal.
3.4 STORMWATER FLOW ANALYSIS
A portion of the stormwater from the Clariant property is treated in the on-site WWTP and a
separate portion is discharged directly into the WWTP effluent canal. Based on the facility
stormwater map (Figure 6—Stormwater Drainage Map)the drainage areas and stormwater flows
that could potentially drain to either of these two (2) locations are estimated.
The drainage areas are divided into several distinct areas as determined by land topography.
Areas 2, 5, 7 &Landfill Cell 3 (not shown on Figure 6)drain to the WWTP. Areas 1, 3 &4
drain directly to the effluent discharge canal (as they have historically).
In order to determine estimated stormwater flows to the WWTP and the effluent discharge canal,
an average precipitation of 0.09"/day for CY 2021 was obtained for the facility from the CLT
airport weather station data. Stormwater flows were estimated based on the Rational Formula, Q
=C*i*A,where i is the rainfall intensity and A is the drainage area.
The runoff coefficient,C, in the Rational Formula for estimating stormwater runoff is expressed
as a dimensionless decimal that represents the ratio of runoff to rainfall. Except for precipitation,
which is accounted for in the runoff formula by using the average rainfall intensity over a
representative time period, all other portions of the hydrologic cycle are contained in the runoff
Clariant NPDES Permit 19 08/23/22
Supporting Documentation

coefficient. Therefore, C includes interception, infiltration, evaporation, depression storage and
groundwater flow.
Impervious areas associated with paved roads, building rooftops, lined basins and other areas
will generally direct stormwater as runoff as opposed to infiltration. These areas will have runoff
coefficients closer to 1. Pervious areas of the facility which allow a higher infiltration rate and as
such allow stormwater runoff only upon saturation have C values closer to 0. For the Clariant
facility based on site topography and conditions, a C value of 0.85 is used for impervious areas
and a C value of 0.25 is used for pervious areas for areas that drain to the WWTP(Areas 2, 5, 7
and Landfill Cell 3).
For areas that drain directly to the effluent discharge canal (Areas 1, 3 &4),these areas are
highly grassed and therefore will have a low C value, which is estimated to be 0.1. These values
along with estimated pervious and impervious areas of each drainage area are used to calculate
the stormwater runoff to the WWTP and the effluent discharge canal as shown in Tables 3-2 &
3-3.

DUP-Sample Duplicate
RPD-Relative Percent Difference
NC-Not Calculable.
SG-Silica Gel-Clean-Up
U-Indicates the compound was analyzed for,but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting.Therefore,calculated parameters that are typically reported as
"Total"may vary slightly from the sum of the reported component parameters.

PQL-Practical Quantitation Limit.
RL-Reporting Limit-The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S-Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270.The result for each analyte is
a combined concentration.
Consistent with EPA guidelines,unrounded data are displayed and have been used to calculate%recovery and RPD values.
LCS(D)-Laboratory Control Sample(Duplicate)
MS(D)-Matrix Spike(Duplicate)
DUP-Sample Duplicate
RPD-Relative Percent Difference
NC-Not Calculable.
SG-Silica Gel-Clean-Up
U-Indicates the compound was analyzed for,but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting.Therefore,calculated parameters that are typically reported as
"Total"may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited.Contact your Pace PM for the current list of accredited analytes.

manufacturing facility in Mount Holly NC. The facility was formerly a specialty chemical and dye manufacturing
site since 1937,but in mid 2005 the production units were shut down. The facility also previously operated as a
•u) centralized waste treatment(CWT)facility but has since ceased CWT operations and does not accept 3rd party
wastes for treatment at its wastewater treatment plant(WWTP). Since there are no CWT operations on-site,the
ar
only treated wastewaters include 1)Sanitary wastewater from site tenants 2)Leachate from an on-site landfill and
stormwater from the facility 3)Intermittent non-contact cooling water from one tenant operation 4)Filter backwash
and fire suppression maintenance system. The facility also has a groundwater pump and treat system that is
currently deactivated with NCDEQ approval on a trial basis since late 2018,but could potentially be reactivated in
the future if needed. These treated wastewaters are discharged to the Catawba River under a NPDES permit issued
