On behalf of Clariant Corporation, Hart & Hickman (H&H) is presenting two copies of the
stormwater permit renewal application for the Clariant Mount Holly East Plant. Please refer to
Appendices A through D, which include the current site map from the Stormwater Pollution
Prevention Plan (SWPPP), a summary of the analytical and visual monitoring results during the
term of the existing permit, a summary of current Best Management Practices utilized at the
facility, and the certification page for the implementation of the site SWPPP respectively. A
short narrative describing significant changes at the facility is provided below.
Clariant ceased all chemical manufacturing operations at the Mt. Holly East facility in July 2005.
From 2005 to 2012, the wastewater treatment plan (WWTP) was used to treat stormwater,
recovered groundwater, tenant wastewater, and third party non -hazardous industrial wastewater.
As of the summer of 2012, Clariant and their on -site staff have been in the process of
decommissioning portions of the WWTP. Clariant will continue to operate the secondary
2923 South Tryon Street, Suite 100 3334 Hillsborough Street

clarifiers for the treatment of wastewater generated from surface water runoff from most of the
developed plant area and groundwater from on -going retuediation activities. Clariant ceased
accepting non -hazardous industrial wastewater from third parties at the end of 2012.
Many of the former buildings including: Buildings 3, 4, 11, 30, 31, 34, 35 & 40A/40B, 44, and
45 have been demolished. Clariant currently leases Buildings 39 and 46 to Monark Industrial
Services. Monark stores chemicals and equipment on the Site and conducts waste stabilization
in a covered concrete pit prior to off -Site disposal. Until recently, portions of the plant were also
leased to CoaLogix/SCR Tech, which regenerates catalyst modules for pollution control systems
used at power plants. CoaLogix/SCR Tech's activities involved handling catalyst modules,
processing chemicals, and use of office space. They previously leased Buildings 21, 32, 48, 49
and 51. CoaLogix/SCR Tech vacated the Site during the summer of 2012. The site is currently
leased by ReVenture Park who plans to redevelop the site into an Eco-Industrial Park.
ReVenture Park is planning to operate a renewable energy process foi ge> LeratuLg elecLiicity Lh.AL
currently uses wood chips and natural gas as primary fuels within Building 21. ReVenture
Park does not have any plans to store chemicals or products in locations at the site that would
adversely affect stormwater.
If you have any questions concerning this document, please do not hesitate to contact me at

Summary of Best Management Practices (BMPs)
Clariant Corporation
Mount Holly East Plant
Charlotte, NC
Stormwater Management BMPs
• Stormwater in areas with a high potential for contamination upon contact is
directed to the on -site waste water treatment plan (WWTP).
• Numerous devices for sediment and erosion control such as riprap, vegetative
filter strips, berms, detention ponds, and silt fences for construction and
demolition activities are present at the facility.
• Wastewater Pump stations
o Stormwater pump stations (East Perimeter and Bldg 30) are inspected bi-
annually or more often if problems are identified to ensure that the pump
is operating properly, the influent and effluent are not clogged with debris,
and that fluid level sensors are working properly.
• Stormwater Valves
u Four storinwater valves (south of Building 45, Bldg 30, upgradient of
Outfall 3A, and east of Building 40) are open under normal operating
conditions. These valves are inspected biannually to ensure that the valves
are free of debris and are operable in case of spills or pump failure.
• Erosion Control Devices
o Stormwater channels are lined with rip -rap and/or vegetation which is
inspected biannually to ensure proper function.
o A site Erosion and Sediment Control plan is in place with the City of
Charlotte An addendum to this plan is submitted to, and approved by, the
City prior to conducting land disturbing activities.
• Other Stormwater Structures
o Catch basins are inspected annually for structural failures and
accumulation of debris.
o Dikes are inspected biannually for evidence of erosion or other evidence

Staff with the Division's Mooresville Regional Office have reviewed your request for a determination that
stormwater discharge outfalls (SDO) OF-8 and OF-9 be granted representative outfall status for stormwater outfalls
OF-3A, OF-31F, OF-5, and OF-10. Based on the information provided, and a site visit conducted on September 27,
2012, by Mr. Michael Parker with this Office, we are hereby approving this request effective immediately. In
accordance with 40 CFR §122.21(g)(7), you are authorized to sample outfalls number OF-8 and OF-9 as
representative outfalls. Sampling of SDO OF-8 and OF-9 should begin at your next representative sampling event.
We also want to remind you that the permit still requires Qualitative Monitoring be performed at all SDOs,
regardless of representative status unless the outfall is not captured by the Phase I stormwater program.
Please append this letter to your Stormwater Pollution Prevention Plan or permit to document that
representative outfall status has been approved. If changes in drainage areas, structures, processes, storage
practices, or other activities occur that significantly alter the basis of this approval, representative outfall status may
no longer be valid. You should either resume sampling at all SDOs, or reapply to this Office for representative
outfall status based on updated Information. If you have any questions or comments concorning this letter, please
contact Mr. Parker at [phone] or via email at Mir,hael Parker@ncdPnr gev

If a facility is required to sample multiple discharge locations with very similar storm water discharges, a( �
permittee may petition the Director for Representative Outfall Status (ROS). DWQ may grant Representative
Outfall Status if stormwater discharges from a single outfall are representative of discharges from multiple
outfalls. Approved ROS will reduce the number of outfalls where analytical sampling requirements apply.
If Representative Outfall Status is granted, ALL outfalls are still subject to the qualitative monitoring
requirements of the facility's permit —unless otherwise allowed by the permit (such as NCG020000) and DWQ
approval. The approval letter from DWQ ►crust be kept on site with the facility's Storm water Pollution
P►eventiun Plun. The facility must notify DWQ In writing if any changes affect representative status.

SWU-ROS-2009 Last revised 12/30/2009

Explanation for Requested Representative Outfall Status
Clariant is proposing two of its six outfalls as representative outfalls for its quantitative stormwater
monitoring — one to represent lire active site and one to represent the sludge landfill area.
Industrial activity at the Clariant Mt Holly East Plant has decreased significantly over the past 15 years.
Most remaining activity occurs in areas that drain to the site's wastewater treatment system and do not
contribute to stormwater outfall discharges. Of the six sampled outfalls, outfalls OF-3A, OF-31F, OF-5,
and OF-8 are located in peripheral areas of the former production site, having only minor industrial
activity consisting mostly of vehicle and equipment traffic along plant roads. OF-8 is being proposed as a
representative outfall for these four dischdrges. OF-8 captures runoff frorn the portion of the site with
the most activity.
OF-9 and OF-10 collect runoff from the vegetated slopes around our active sludge landfill. OF-9 will
produce sufficlent runoff to sarnple from a moderate rain event. O -'10 does not have a large watershed
area and includes a shallow vegetated collection impoundment that absorbs even heavy rains if they
have been preceded by an extended dry period. Few rain events within each six months produce
sufficient runoff to collect a sample from OF-10. OF-9 is being proposed as a representative outfall for
these two outfalls.
Attached is a summary of stormwater quantitative data for 2010-2012 to support the requested
representative outfall designations. The outfalls are listed in two representative groupings and the two
proposed ROS outfalls are shaded grey. While there is variability from outfall to outfall, there is greater
variability within individual outfalls from event to event.
The two second -half 2011 storm events that were sampled were abnormally heavy (5.8" & 2.8"), the
first of which caused a major flood in the Mt Holly area. The high TSS levels for OF-5 & OF-8 which
exceeded benchmark values for this sampling event were attributed to the torrential nature of these
storms.
The measured pHs of the outfalls is strongly affected by acid rain. The degree of acidity depends on the
nature of the rain event and the time of sampling within the 30 minute window A significant portion of
Of-3f watershed consists of an empty asphalt paved area. Testing has demonstrated Ural the irrilial
outfall flow originates from this paved area and is quite acidic from acid rain. The in -spec but
uncharacteristically high pH in OF-5 in the second sampling period of 2010 was likely from fresh
concrete that was poured in this drainage area.
Clariant believes the two outfalls proposed are representative of the stormwater quality that can be
expected from the active portions of the facility.

Re: Clariant Corporation, Mt. Holly East Facility, Draft NPDES Permit Number NCS000037.
Dear Mr. Patterson. -
This letter is to provide Clariant's comments on the Draft NPDES Stormwater Permit we received from
your office on November 6, 2009. Our only comment is on the frequency of the quantitative monitoring
specified in the draft permit. Our current permit requires quantitative monitoring once per year. Given
the many years of sampling history at the site, the limited industrial activities in the watershed areas
and the overall good quality observed in our storrnwater discharges, we request that the quantitative
rnuniloririg remain on an annual basls.
If you have any questions or nc;t;d more irifurmation, please coniacl rrie at (704) 322-2/02 or

Permit No. NC:S000037
Mount Holly East (MHE) Facility.
Meeldenburg County
Dee Freeman
Secretary
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please review the draft very
carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from this. facility's. current permit:
Analytical monitoring changes:
1. Analytical monitoring parameters'have changed in this permit. Monitoring for Phenols has been removed.
pH has been added to the analytical monitoring requirements perour revised monitoring strategy.
2. All analytical monitoring has been set to semi-annually during a representative storm event as defined in
Part II Section B. The permittee must also document the total.precipitation for each event. If no discharge
occurs during the sampling period, the permittee must submit a monitoring report indicating ".No Flow"
within 30 days of the end of the six-month sampling period. Additionally, samples must be taken a
minimum of 60 days apart, as specified in Table 2.
3. Benchmarks for analytical monitoring have been added to this draft permit. 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. If the sampling,, results
aie above a benchmark value, or outside of the benchmark range, for any parameter at any outfall then the
facility shall follow the Tier 1 guidelines which require a facility inspection within two weeks and
iuipleuienL-ation of a mitigation plan within two months. If during the term of this permit, the sampling
results are above the benchmark values, or outside of the benchmark range, for any specific parameter at a
specific discharge outfall two times in a row (consecutive), then the facility shall follow the Tier 2 guidelines
which require a repetition of the steps listed for Tier 1 and also immediately institute monthly monitoring
for all parameters at every outfall where a sampling result exceeded the benchmark value for two
consecutive samples.
4. You are required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part II Section B. Qualitative monitoring is required regardless of representative
outfall status.
5. You are responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1, 4, and
5.

6. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter
is in this permit, however.)
7. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring. This requirement appears in all Individual Stormwater permits, however it only
applies to facilities that do vehicle maintenance if the facility begins vehicle maintenance during the
permitted timeframe then the requirements shall apply.
Other permit changes:
1. Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants in
each outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of
significant spills that have occurred in the past three years and also must certify that the outfalls have been
inspected to ensure that they do not contain non-stormwater discharges. Additional information is
provided in Part II Section A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part II Section A.
Moie details iegniding secondwy cottlahaneuL aie provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part 11 Section
A. The plait must also be updated annually to include a list of'significant. shills and to certify that the
outfalls do not contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part II Section A.
5. Information regarding the No Fxposure Exclusion has been added to this draft permit. if industrial
materials and activities are not exposed to ptec:ipilution or futtoff as described ht 40 CFR §122.26(g), the
facility may qualify for a No Exposure Exclusion from NPDES stormwater discharge permit requirements.
Additional information is provided in Part I Section A.
6. Per the requirements of the Catawba Riparian Buffer Rule, all stormwater drainage from portions of
this site that have been constructed after June 30, 2001 must be discharged, through a correctly designed
level spreader or another device that meets diffuse flow requirements per 15A NCAC 2B .0243. Diffuse.
flow requirements are described in Chapter 8 of the North Carolina Stormwater BMP Manual, available
at: http://h2o.enr.state.nc.us/su/bmp_forms.htm
Please submit any comments to me no later than thirty (30) days following your receipt of the draft. Comments
should be sent to the address listed at the bottom of this page. If no adverse comments are received from the
public or from you, this permit will likely be issued in about two months.

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a representative storin event. The required
inonitoting will tesull ill a ininiinutn of len analytical samplings being conducicd over [lie lean of
the permit at each stormwater discharge outfall (SDO).
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 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. For example, if it rains for 2 hours without producing any collectable discharge,
and then stops, a sample may be collected if a rain producing a discharge begins again within the
next 10 hours.

This site discharges to impaired waters experiencing problems with turbidity. A Total
Maximum Daily Load (TMDL) was approved for this segment of Long Creek. Therefore, the
permittee is required to monitor for the pollutant(s) of concern (TSS) and submit results to the
Division of Water Quality. The Division will consider the monitoring results in determining
whether additional BMPs are needed to control the pollutant(s) of concern to the maximum
extent practicable.
If additional BMPs are needed to achieve the required level of control, the permittee will be
required to (1) develop a strategy for implementing appropriate BMPs, and (2) submit a timetable
for incorporation of those BMPs into the permitted Stonnwater Pollution Prevention Plan.

SECTION C: QUALITATIVE MONITORING REQUIREMENT'S
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status and shall be performed as specified in Table 4, during the analytical
monitoring event. [If analytical monitoring is not required, the permittee still must conduct semi-
annual qualitative monitoring.] Qualitative monitoring is for the purpose of evaluating the
effectiveness of the Stormwater Pollution Prevention Plan (SPPP) and assessing new sources of
stonnwater pollution.
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.

H&H Project No. CLR-012
Dear Ms. Lau:
On behalf of Clariant Corporation, Hart & Hickman (H&H) is presenting two copies of the stormwater
permit renewal application for the Clariant Mount Holly East Plant. Please refer to Appendices A
through D which include the current site map from the Stormwater Pollution Prevention Plan
(SWPPP), a summary of the analytical and visual monitoring results during the term of the existing
permit, a suirnnaiy of current Best Management Practices utilized at the facility, and the certification
page for the implementation of the site SWPPP respectively. A short narrative describing significant
changes at the facility is provided below.
Clariant ceased all chemical manufacturing operations at the Mt. Holly East facility in July 2005.
Buildings 3, 4 & 40AJ40B shown on the previous Stormwater Site Map have been demolished.
Buildings 11, 30, 31, 34, and 35 are planned for demolition by the end of 2007. The Picric Acid
Storage area and Sandblast area shown on the previous Stormwater Site Map are no longer in use. The

Ms. Lau
October 26, 2007
Page 2
Area C Soil Pile has been removed, as has most of the equipment that was stored in the Salvage Yard.
The 350 gallon diesel tank northeast of Bldg 37 has been relocated to another Clariant facility.
Clariant leases portions of its facility to two tenants. The largest tenant is SCR Tech who regenerates
catalyst modules for pollution control systems used at power plants. SCR Tech's activities which
involve handling catalyst modules or processing chemicals are conducted either within processing
buildings or on paved areas which direct stormwater flow to Clariant's onsite treatment plant. SCR
Tech leases Buildings 21, 32., 48, 49 and 51. The second tenant is Monark Industrial Services. Monark
is locatod in tho urou botwoort buildings 30 & 46 Mouurl< store„ eKluiptnettt 011 [110 SitO and oonduots
waste stabilization in a covered concrete pit. Except for empty tank trailers and truck cabs which are
sometimes stored on the "Empty Trailer Storage Area" below Building 53, runoff from Monark's
operations is captured by the onsite wastewater sewer.
There are two stormwater valves at the facility that were previously closed during normal operating
conditions (south of Building 45, east of former Building 40). When these valves are closed surface
water from the area is routed to the site WWTF. Due to the elimination of chemical processing
activities at the site, Clariant plans to now open these valves to route non -contact rainwater towards
adjacent outfalls #8 and 3A. The Site Stormwater Map (Appendix A) depicts the area of the site where
non -contact surface water will flow through the open valves towards the outfalls. These valves are
operable in the case of spills or wastewater pump station failures.
Clariant continues to operate its wastewater treatment facility for treating wastewater from surface
water runoff from most of the developed plant area, groundwater ftom ongoing remediatiou activities,
and industrial wastewater from third parties.
Based on cessation of organic chemical manufacturing operations at the site and non -detection of
phenols in the quantitative stormwater results during the current permit term, Clariant requests that
Total Phenols be dropped as a required analysis in the renewed permit. We also request that the
frequency of quantitative and visual monitoring be kept to a minimum because of the high number of
outfalls and the greatly reduced activity at the site.

Summary of Best Management Practices (BMPs)
Clariant Corporation
Mount Holly East Plant
Charlotte, NC
Stormwater Management BMPs
• Stormwater in areas with a high potential for contamination upon contact is
directed to the on -site waste water treatment plan (WWTP).
• Numerous devices for sediment and erosion control such as riprap, vegetative
filter strips, berms, detention ponds, and silt fences for constriction and
demolition activities are present at the facility.
• Wastewater Pump Stations
u SLouuwaLei pump stations (East Peihnetci acid Bldg 30) aie inspected bi-
annruGally or more ollen il' problenis are idenLilied to ensure that the pump
is operating properly, the influent and effluent are not clogged with debris,
and that fluid level sensors are working properly.
• Stormwater Valves
o Four storrnwater valves (south of Building 45, Bldg 30, upgrradient of
Outfall 3A, and east of Building 40) are open under normal operating
conditions. These valves are inspected biannually to ensure that the valves
are free of debris and are operable in case of spills or pump failure.
• Erosion Control Devices
o Stormwater channels are lined with rip -rap and/or vegetation which is
inspected biannually to ensure proper function.
o A site Erosion and Sediment Control plan is in place with the City of
Charlotte. An addendum to this plan is submitted to, and approved by, the
City prior to conducting land dhAutbinb activities.
• Other Stormwater Structures
o Catch basins are inspected annually for structural failures and
accumulation of debris.
o Dikes are inspected biannually for evidence of erosion or other evidence
of failure.
o Earthen dikes are stabilized by a vegetative cover.
o Stormwater structures are properly maintained and repaired as necessary.
1

• Maintenance of Vehicles and Equipment
o Vehicles maintenance is conducted in a garage building within the area
tributary to the WWTP.
o Drip pans are utilized for the collection of fluids within the garage.
o All fluids and other hazardous automotive materials are disposed of
properly.
Hazardous Material Storage and Handling BMPs
• Secondary containment is provided for the bulk storage of chemical materials in
areas tributary to surface waters in order to contain leaks and to control and divert
runoff. Floor drains are connected to the site wastewater treatment plant
(WWTP).
• Chemical materials are stored inside the site's warehouses and production
buildings and arc used or processed in areas that drain to the WWTP.
• Loading and unloading operations (only in limited areas of the site)
o Are conducted in areas that drain to the WWTP
o Bulk liquids are not transferred unless a responsible facility employee is
present.
o Spills are promptly remediated according to the contingency plan.
• Lawn chemicals
o Lawn chemicals are applied according to manufacturer's instructions and
are disposed of properly.
o Lawn chemicals are not applied if rainfall is expected to occur soon after
application.
• Material Storage Practices
o All containers are covered or closed when not in use. Bulk containers are
maintained within secondary containment.
o Containers are stored away from traffic areas.
(.) Spill cleanup materials arc available onsite.
Preventative Maintenance and Good Housekeeping BMPs
o Housekeebina Practices
■ Employees receive proper training on housekeeping techniques.
■ Spills are contained and remediated immediately upon detection.
■ Containers storing chemicals are evaluated and corrected as
needed.
■ Containers are covered or closed when not in use. Bulk containers
are maintained within secondary containment (if applicable).
■ Chemicals are not stored on exposed soils.
2

Spills are contained to prevent release to storm drains that drain to
the Catawba River or Long Creek.
Discharge valves in active containment dikes are closed at all
times.

NPDF,S Stormwater Permit No. NCS000037
Mecklenburg County
Per your request, this Office has reviewed the request submitted by Victor B. Ethridge, Senior
Environmental Chemist, Clariant Corporation to convert process water/storm sewer lines at the subject
facility to Stormwater (SW) only. The following comments/recommendations are offered.
As a result of company downsizing, Clariant plans to eliminate certain areas of it's
manufacturing process. This elimination of certain manufacturing processes also includes a
downsizing of the existing W WIT since hydraulic flows are expected to be lower. For this reason, S W
flows currently tributary to the WWTP will need to be redirected to surface waters at existing permitted
SW outfalls. Currently, Clariant has piping that carries both SW and SW/process water (combined
sewer). All this flow is currently tributary to the WWTP. Once the process water has been eliminated
from the combined SW sewers, Clariant plans to check each line for illicit connections, submit the
lines to a rigorous cleaning to remove any contaminants that might be present (cleanliness will be
verified thiougli sampling of the rinsate), and then use the lines for SW transport only. During the
process of rerouting SW and process water flows, additional piping will be necessary that will
necessitate changes (ie. new outfalls) in the subject SW permit.
This Office has reviewed Mi. Etlaidge's request turd finds it uccepLuble provided the SW Unit
concurs with the sampling protocol and standards for determining cleanliness. It should also be noted
that a reduction in hydraulic flow to the company's WWTP may also warrant a change in the
company's NPDES Permit to account for the lower hydraulic flow.
If you have any questions regarding this matter, please advise.

AND NATURAL RESOURCES
MOORESVILLE REGIONAL OFFICE
Clariant has proposed to eliminate some of the industrial activities at the Subject plant and render
some areas no subject to Ston-riwater NPDES. Other areas of the facility are presently draining
their storm runoff into the wastewater treatment plant and the stormwater from these areas are
proposed to be diverted to the surface waters directly and included in the existing NPDES
stormwater permit NCS000037. The details of their plans are shown on the attached submittal.
I would appreciate your regional office perspective on this proposed modification to their permit
and drainage regime. Given the travel restrictions we are faced with, I would not expect to make a
trip down to Clariant but if you plan a site visit please let me know of the date so that I can
consider it should I be in the area on other matters.
Thanks for your help. (I am keeping the original of the narrative but the drawings are the only set
they hiovided, I will need them back).

RE: Conversion of Combined Sewer Lines (Process Sewer/Storm Sewer) To
Stormwater Only Sewer Lines
Clariant Corporation — Mount Holly East Plant
Stormwater Discharge Permit Number NCS000037
Dear Mr. Mills:
Clariant Corporation's Mount Holly East plant has an individual stormwater discharge permit
(NCS000037), which allows it to discharge stormwater to two surface water bodies, Long Creek
and the Catawba River. The stormwater outfalls covered in Clariant's stormwater discharge
permit flow to both of these two surface water bodies.
However, for a majority of the developed portion of the site (particularly where industrial
activity occurs), stormwater does not enter catch basins or drainage features which lead to
surface waters. Ratltei, the stuiinwatei flows to Clwiant's on, wastewater treatment system
where it is aerobically treated and eventually discharged to the Catawba Rivei. Most of the
storm sewer lines in the developed portion of the site are actually combined sewers which carry
process/sanitary wastewaters and stormwater. All of these combined -flow lines lead to the
plant's on -site wastewater treatment system. Consequently, most of the stormwater runoff from
the site is actually treated in an aerobic wastewater treatment system instead of flowing directly
to a surface water body.
Currently, Clariant has plans to downsize the Mount Holly East manufacturing site, and this
includes a plan to downsize the on -site wastewater treatment system. Because of this, Clariant
will need to reduce the volume of stormwater entering the treatment system. The downsized
wastewater treatment will not be able to adequately handle to hydraulic loading contributed by
the current volume of stormwater.
Therefore, Clariant will need to divert some of the stormwater currently entering its wastewater
treatment system to Long Creek and to the Catawba River.

Essentially, Clariant plans on accomplishing the diversion by converting the combined sewers
described above to "stormwater only" sewers. After the mothballing of affected manufacturing
buildings and, in some cases, the demolition of some manufacturing buildings, there will no
longer be process wastewater flow in the combined sewer lines. The only flow through these
lines would be stormwater runoff.
Clariant would investigate the lines to assure that there are no illicit discharges in the lines slated
for conversion to storm sewers. We would not expect there to be any of these types of
discharges since the mothballing of the buildings would involve actually disconnecting water
supply and power supply from the buildings. We would then begin the cleaning of the diverted
sewer lines.
Because these combined sewers formerly handled process waste, Clariant has proposed a
iigoious cleaning protocol befuie the conversion takes place. Furthermore, part of this cleaning
protocol is also verification of cleanliness for sewer piping and junction boxes. This verification
is essentially a sampling of the rinsate from the cleaning operations. The cleaning protocol
requires that the concentration of constituents in the rinsate be below the site's RCRA permit
groundwater protection standards. Attached is a comparison of Clariant's groundwater
protection standards to the Safe Drinking Water Act's Maximum Contaminant Levels (MCL's).
As you can see, Clariant's groundwater protection standard concentrations are less than or equal
to the MCL's (with the exception of p-dichlorobenzene). A copy of the sewer cleaning protocol
is also attached as a separate document.
For the purpose of simplicity, there will basically be two (2) main diversions: one on the eastern
side of the site and one on the northwestern area of the site. The enclosed drawing shows the
details of the diversions. The Eastern diversion will involve the most linear feet of sewer line
conversion. These sewer lines now serve as combined sewers to carry process waste and
stormwater to the on -site wastewater treatment system. The Northwestern diversion will involve
substantially less sewer conversion. These sewer lines now serve mainly to carry stormwater
and boiler blowdown water to the on -site wastewater treatment system.
As shown on the attached drawing (Area 2 — Drawing Number 3 8081102), the Eastern diversion
calls for brc;aking the combined sewer lines coming Burn [lie former production buildings 39, 40,
and 46. These broken Imes would be tied in to newly added junction boxes and ultimately re-
routed to the current stormwater Outfhll 3F. Outfall 3F discharges stormwater to Long Creek.
After this diversion has been made, Clariant plans to re -sample Outfall 3F and analyze the
stormwater run-off for those parameters analyzed for in the original sampling of this outfall. The
results of this sampling will be submitted to the Stormwater Section with the appropriate
documentation when it becomes available. The Outfall 3F sampling will be done after all of the
demolition and sewer re-routing have been completed. The estimated time schedule for the re -
sampling is late 3rd Quarter 2001.

Essentially, the eastern portion of the plant site will become inactive. The production buildings
and warehouses in this portion of the plant will be either "mothballed" or razed. Since industrial
activity will no longer be occurring in this area of the plant, three (3) currently permitted
stormwater outfalls (Outfalls 3A, 3B, and 3C) will need to be removed from the permit. Outfalls
3D and 3F will need to remain a part of the permit because industrial activity will continue to
occur in areas draining to these outfalls.
The Northwestern diversion (Area 1 — Drawing Number 38081101) calls for re-routing all
sanitary and boiler blowdown flow to a different alkaline process sewer line to the south of
Building 1. After the re-routing of the sanitary/boiler blowdown flow, the only thing remaining
in the sewer lines north of Building 1 will be stormwater flow. Therefore, this line will be
broken and diverted to the Catawba River as shown in the attached drawing. This will create a
new stwinwater outfall which diseltaiges to the e:ulvelt system ill the northwest corner of tl►e site.
Although the Boiler Room and Fuel 'Tank in this area will still be operational, all of the
stormwater drainage from these areas will flow to the site's wastewater treatment system. The
fuel truck unloading area and the fuel tank containment dike both drain to the site's wastewater
treatment system.
Since there will be no industrial activity in the area draining to the newly created outfall, Clariant
does not intend to include it as part of the stormwater permit modification. Therefore, no
sampling of this outfall is planned.
The demolition work will probably take place in late spring 2001. The sewer diversion project
will take place after the demolition/mothballing described above has been completed.
Clariant would like to make these changes to its Stormwater Discharge Permit after all of the
proposed storm sewer modifications have been made. We would also like to know if the
Stormwater Section has any problems or suggestions with the proposed actions described above.
We are available to meet with you to discuss these proposed modifications at your convenience.
The Section is also welcome to visit the site to take a look at the proposed modifications
described above.
Should you have any questions or need any additional information, please call me at (704) 822-
4485.
Sincerely,

Process Sewer System Cleaning Protocol
The purpose of sewer clean -out procedures is to remove residual materials which could be
sources of releases to soil, groundwater or surface water if left in place. Because the sewers are
gravity drained, low points where large volumes of raw wastewater could be held are not
anticipated. Water rinsing will be used to remove water-soluble residuals. Non -water soluble
residuals will be removed by rinsing at a sufficient velocity to mobilize solid depositions out of
the sewer segment being converted to stormwater sewers.
The diversity of sewer materials of construction, piping configurations and length/slope of sewer
runs requires a variety of sewer component clean -out procedures. Clariant reserves the right to
substitute equally effective procedures fui sewei cleaning. Selection of cleaning methods will be
made based on the methods ability to meet criteria presented below.
Sewer components will be cleaned from junction box to junction box working from upstream to
downstream.
Clean -out procedures must meet the following criteria -
Criterion 1: The entire length and cross-section of a line must be rinsed at least once;
Criterion 2: Accumulated solids must be removed;
Criterion 3: Junction boxes must be emptied of liquids and solids and triple -rinsed
with fresh water, preferably under high pressure: and
Criterion 4: Clean -out will be complete when the above criteria have been met and the
concentrations of VOCs (Method 8260), SVOCs (Method 8270) and
metals (Table 1 3) in a grab sample of wash water and junction box rinsate
are below GWPS listed in Table VI-1 of the RCRA permit.
For the purposes of cleaning, an empty junction box will be a box which has had free liquids
removed to the extent possible by pumping. An empty sewer section is a sewer line which has
been gravity drained of liquid.
l�
u� { 1 2mf-
JAN

k
Examples of methods which can be used to meet Criteria 1 and 2 are as follows:
1) Plug the line (using packers or other suitable pipe plugging devices) at the point where it
enters a downstream junction box. Fill the line with wash water from the upstream junction box
until the upstream junction box is filled. Remove the downstream plug and allow the line to
drain through the downstream junction box. This will provide a complete one-time rinsing of the
entire length and cross-section of the sewer line (meets Criterion 1).
2) Plug lines exiting the downstream junction box (leaving the line to be cleaned up -plugged).
Flush water tluuugh the line CroutY the upstream junction box Use a submersible pump to
recirculate water from the downstream junction box to the upstream junction box. For relatively
short sewei sections with moderate slopes, this will be a practical way to provide repeated
rinsing of the entire sewer length and cross-section (meets Criterion 1).
3) Lines can be hydrocleaned using a high velocity, high pressure water system. Nozzles will
be moved through the pipeline and rotated to produce scouring against the surface of the pipe
cross-section. Hydrocleaning will be followed by a thorough high volume rinsing from upstream
to downstream to convey solids to the downstream junction box for removal (meets Criterion 1
and Criterion 2).
4) Using fire hoses or a similar source of high volume, relatively high velocity water, the
sewers may be rinsed by providing enough water at a high enough velocity to produce
scouring along the bottom third (invert) of the sewer cross-section. This portion of the cross-
section is the area of the line which will have received the most flow over time, and therefore
will have had the most contact with potentially hazardous constituents. Additionally, the
sewer invert has the highest likelihood of having bad solids deposition over time. For the
purposes of cleaning the sewer, a velocity of 3 feet per second with rinsing over the lower
third of the sewer will be considered adequate. For sewers conveying liquid with significant
solids content, a design velocity of 2 reef per second is generally considered adequate to
provide effective scouring (Tchobanoglous, 1981. p. 109). To conserve water, Clariant may
choose to recycle rinse water by pumping from lie downstream junction box to the upstream
junction box. Should recycling be implemented, the final rinse will be of fresh water. This
type of cleaning will continue until solids are no longer being observed entering the
downstream junction box (meets Criterion 2).
Criterion 3 will be met by triple rinsing the junction box after removing free liquids and solids
by pumping. Triple rinsing will be performed using a fire hose, pressure washer or equivalent
water delivery device. Rinsate, including the water generated by cleaning the sewer lines, will be
pumped from the box and discharged to the wastewater treatment plant.

Criterion 4 will be verified by analyzing a grab sample of rinsate from the final sewer line
cleaning and the third rinsing of the junction box for VOCs (Method 8260). SVOCs (Method
8270) and metals (Table 1-3). Sample collection, containerization, handling, chain -of -custody
and other quality assurance/quality control will be performed in accordance with protocols
referenced in Section I and in Appendix A.
Sewer and junction box cleaning will be considered complete if the analytical results are found
to be less than or equal to GNATS listed in Table VI-1 of the RCRA Permit. If the analytical
results are above the applicable GWPS, the appropriate cleaning procedures described in this
section will be repeated and additional samples will be collected and analyzed.

Your facility is currently covered for stormwater discharge under NPDES Permit NCS000037. This permit
expires on August 31, 1999. In order to assure your continued coverage under your permit, you must apply to the
Division of Water Quality (DWQ) for renewal of your permit. To make this renewal process easier, we are
informing you in advance that your permit will be expiring. Enclosed you will find an individual permit renewal
application form, supplemental information request, and Stormwater Pollution Prevention Plan certification.
Filing the application form along with the requested supplimental information will constitute your application for
renewal of your permit. The application form must be completed and returned along with all requested
information within thirty days of receipt of this letter in order to constitute a timely renewal filing.
Recent legislation modified the fee structure for DWQ permits. Renewal fees have been eliminated and annual
fees have been changed. The new annual fee for your permit is now $715.00 (you will be invoiced later this year
for your annual fee.) A copy of the new fee schedule is enclosed in this package.
Failure to request renewal within the time period indicated may result in a civil assessment of at least $250.00.
Larger penalties may be assessed depending on the delinquency of the request. Discharge of stormwater from
your facility without coverage under a valid stormwater NPDES permit would constitute a violation of NCGS
143-215.1 and could result in assessments of civil penalties of up to $10,000 per day.
