Dear Mr. Golder:
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. Analy tical monitoring parameters, Oil and Grease, BOD, COD, TSS, Phenols and pH, have been
maintained in this permit.
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 are 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 . eks and implementation of a m.itiga on purl within two nionntlns. If during tine 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 oiltfall. 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 itutt-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.
More detetils regaidittg seco ndwy coittxuurteitt are provided.
3. Additional requirements for the Stormwater Pollution Prevention PIan have been. specified in Part 11
Section A. The plan must also be updated annually to include a list of significant spills and to certify that
the outfalls do not contain non-stormwater discharges.
4. The facility must now implement_awe_mi=a_nnuallac lity_I spectionPxngram of the site's storrnWater =- - -
management controls as specified in Part II Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial
materials and activities are not exposed to precipitation or runoff as described in 40 CFR §1.22.26(g), the
facility may qualify for a No Exposure Exclusion from NP,DES 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: httn://h2o.enr.state.nc.us/su/-bmp forms htm

PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The Permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. This Plan shall be considered public information in accordance with Part III, Standard
Conditions, Section E, Paragraph 3 of this individual permit. The Plan shall include, at a
minimum, the following items:
1. Site Plan. The site plan shall provide a description of the physical facility and the
potential pollutant sources which may be expected to contribute to contamination of
stormwater discharges. The site plan shall contain the following:
(a) A general location map (USUS quadrangle map or appropriately drafted
equivalent map), showing the facility's location in relation to transportation routes
and surface waters, the name of the receiving water(s) to which the stormwater
outfall(s) discharges, or if the discharge is to a municipal separate storm sewer
system, the name of the municipality and the ultimate receiving waters, and
accurate latitude and longitude of the point(s) of discharge. The general location
map (or alternatively the site map) shall identify whether each receiving water is
impaired (on the state's 303(d)'list of impaired waters) or is located in a
watershed for which a TMDL has been established, and what the parameter(s)
of concern are.
(b) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices. A narrative description of the potential pollutants which
could be expected to be present in the stormwater discharge from each outfall.
(c) A site map drawn to scale (including a distance legend) showing: the site property
boundary, the stormwater discharge outfalls, all on -site and adjacent surface
waters and wetlands, industrial activity areas (including storage of materials,
disposal areas, process areas, loading and unloading areas, and haul roads), site
topography, all drainage features and structures, drainage areas for each outfall,
direction of flow in each drainage area, industrial activities occurring in each
drainage area, buildings, existing BMPs, and impervious surfaces. The site map
must indicate the percentage of each drainage area that is impervious.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the three (3) previous years and any corrective actions taken to mitigate
spill impacts.
(e) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The certification statement will be signed in
accordance with the requirements found in Part III, Standard Conditions, Section
Part II Page 1 of 9

Permit No. NCS000041
B, Paragraph 5. The permittee shall re -certify annually that the stormwater
outfalls have been evaluated for the presence of non-stormwater discharges.
2. Stormwater Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. Wherever practical, the permittee shall
prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations In areas where elimination of exposure is
not practical, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
(b) Secondary Containment Requirements and Records. Secondary containment is
required for: bulk storage of liquid materials; storage in any amount of Section
313 of Title. III of the Superfiind Amendments and Reauthorization Act (SARA)
water priority chemicals; and storage in any amount of hazardous substances, in
order to prevent leaks and spills from contaminating stormwater runoff. A table
or summary of all such tanks and stored materials and their associated secondary
containment areas shall be maintained. If the secondary containment devices are
connected to stormwater conveyance systems, the connection shall be controlled
by manually activated valves or other similar devices (which shall be secured
closed with a locking mechanism), and any stormwater that accumulates in the
containment area shall be at a minimum visually observed for color, foam, outfall
staining, visible sheens and dry weather flow, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated by any material. Records documenting the individual malting the
observation, the description of the accumulated stormwater, and the date and time
of the release shall be kept for a period of five years.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMP) shall be provided. The installation and implementation of BMPs
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and data collected
through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMP Summary shall be reviewed and updated annually.
Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or the team) responsible for implementing the
SPRP shall be identified in a written list incorporated into the SPRP and signed and dated
by each individual acknowledging their responsibilities for the plan. A responsible
Part II Page 2 of 9

Permit No. NCS000041
person shall be on -site at all times during facility operations that have the potential to
contaminate stormwater runoff through spills or exposure of materials associated with the
facility operations. The SPRP must be site stormwater specific. Therefore, an oil Spill
Prevention Control and Countermeasure plan (SPCC) may be a component of the SPRP,
but may not be sufficient to completely address the stormwater aspects of the SPRP. The
common elements of the SPCC with the SPRP may be incorporated by reference into the
SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance and good housekeeping program shall be developed. The program shall list
all stormwater control systems, stormwater discharge outfalls, all on -site and adjacent
surface waters and wetlands, industrial activity areas (including material storage areas,
material handling areas, disposal areas, process
haul roads), all drainage features and structures
program shall establish schedules of inspection

6. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be documented
and position assignments provided.
7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants to surface waters. All aspects of the
Stormwater Pollution Prevention Plan shall be reviewed and updated on an annual
basis. The annual update shall include an updated list of significant spills or leaks of
pollutants for the previous three years, or the notation that no spills have occurred. The
annual update shall include written re -certification that the stormwater outfalls have been
evaluated for the presence of non-stormwater discharges. Each annual update shall
include a documented re-evaluation of the effectiveness of the BMPs listed in the BMP
Summary of the Stormwater Management Plan.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall
Part 11 Page 3 of 9

Permit No. NCS000041
submit a time schedule to the Director for modifying the Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part III, Standard Conditions, Section B, Paragraph 5) to the Director that the changes
have been made.
8. Facility Inspections. Inspections of the facility and all stormwater systems shall occur as
part of the Preventative Maintenance and Good Housekeeping Program at a minimum on
a semi-annual schedule, once during the first half of the year (January to June), and once
during the second half (July to December), with at least 60 days separating inspection
dates (unless performed more frequently than semi-annually). These facility inspections
are different from, and in addition to, the stormwater discharge characteristic monitoring
required in Part II B and C of this permit.
9. Implementation. The permittee shall implement the Plan. Implementation of the Plan
shall include documentation of all monitoring, measurements, inspections, maintenance
activities, and training provided to employees, including the log of the sampling data and
of actions taken to implement BMPs associated with the industrial activities, including
vehicle maintenance activities. Such documentation shall be kept on -site for a period of
five years and made available to the Director or the Director's authorized representative
immediately upon request.

Permit No. NCS000041
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 storm event. The required
monitoring will result in a minimum of ten analytical samplings being conducted over the term 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. The time
between this storm event and the previous storm event measuring greater than 0.1 inches must be at least
72 hours. A single storm event may have a period of no precipitation of up to 10 hours. For example, if
it rains but stops before producing any collectable discharge, a sample may be collected if the next rain
producing a discharge begins within 10 hours.

Central Office Review Summary:
1. Owner's Other Permits:
• NCG500047 — Non -contact Cooling Water
• CAA—100000131216, NE154266
• WQ0002544 — Land Application of Residual Solids
2. General Observations:
• The site map shows seven outfalls. Only five of these outfalls actually discharge to the river, and only
these five will be monitored. Outfall 2 is not in use and has been disconnected from all sources. Outfall 7
discharges into Outfall 6 and so only Outfall 6 is an actual discharge point.
3. Impairment: The Catawba River is not on the 2006 303(d) list. Basinwide Plan does not specifically talk about
this section of the Catawba River but it does note that this area in experiencing rapid growth with new homes
and businesses sprouting up on old farms and forests.
4. Threatened and Endangered: Based on Natural Heritage Virtual Workroom there are no federal protected
aquatic species within two miles of the site. There is Helinathus schweinitzii or Schweinitz's Sunflower which
is endangered.
5. Location: WS-IV; CA -Critical Area (CA) is the land adjacent to a water supply intake where risk associated
with pollution is greater than from remaining portions of the watershed. Critical area is defined as land within
one-half mile upstream and draining to a river intake or within one-half mile and draining to the normal pool
elevation of water supply reservoirs. Critical areas are more restrictive than areas outside this area.
Industrial Changes Since Previous Permit: Activities at Clariant's Mount Holly West (MHW). facility have been
relatively consistent during the duration of the facility's existing stormwater discharge permit. Very few changes
are significant in terms of site activities or their effect on stormwater.
Changes in Production: A production area, Building 190, was shut down, decommissioned, and partly
demolished. This area was formerly used to manufacture a detergent additive. The product was discontinued.
Production activities in our area known as Plant 2 were shut down and moved into our area known as Plant 5.
Stormwater from the vicinity of Plant 5 discharges to Outfall 006.
Changes in storage practices: Outside storage of chemical -containing totes and drums has been reduced by
10%. This was accomplished by improvements in inventory management, and by clearing space inside our
warehouse. Several outside storage areas have been eliminated.
Changes in stormwater control systems: A barricade of rip rap was.put in place east of our Building 190 area to
intercept gravel from being washed into stormwater Outfall 004.
A gate was installed at Outfall 006 for emergency use to contain any spills at our Plant 1 area. The containment
system drains into our on -site wastewater pretreatment plant (WWTP).
Secondary diversion curbing and road humps were constructed in selected locations on the east side of our plant.
(Specific locations include: near and to the south and east of our wastewater list station and Outfall 003
containment area;. and in the road southwest of our wastewater pretreatment facility). These enhance our
capability to manage certain spills that might potentially head towards Outfall 004 or Outfall 006.
Floor drains in our production buildings were rebuilt and/or sealed off to prevent the possibility of seepage from
possibility of seepage from process sewer drains into the SW systems.
The stormwater containment area at Outfall 003 was provided with the installed capability to pump stormwater
into our wastewater light station. This facilitates our ability to send stormwater, if contaminated, into our
WWTP instead of releasing it through the outfall.
Two cooling towers located at Plant 3 had their blowdown piping modified to allow the option of discharging
blowdown water into our WWTP instead of Outfall 001, if necessary.
Page 4 of 9

NCS000041
Process wastewater and stormwater systems in the Plant 5 area were upgraded to reduce the chance of crossover
contamination or overflow. For example, a curb was constructed between different types of sumps to separate
containment areas. Piping cross connections were physically disconnected to eliminate any possibility of process
wastewater for entering stormwater through shared piping. High level alarms were installed on all wastewater
and stormwater sumps in the Plant 5 area.
Analytical Monitoring Notes: Samples were taken at 6 outfalls from 6/15/03 to 5/11/09. There were many
values over our current benchmarks for COD and TSS. They were at outfalls: 1, 3, 4, 6 and 7. One value was
below the range for pH at outfall 7.
Based on the SIC code the EPA Multi -Sector General Permit covers the facility in Sector C - Chemical and
Allied Products Manufacturing, and Refining. However, no parameters were recommended for monitoring.
8. Qualitative Monitoring: The visual monitoring showed some muddy clarity and some suspended solids
during a couple rain events. Thirteen reports were submitted and overall there were few issues.

NCS000041
Revised Permit Recommendations: Analytical Monitoring:
1. Maintain monitoring for Oil and Grease, BOD, COD, TSS, Phenols and pH because they remain a potential
pollutants on site.
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 are 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 implementation 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. The permittee is 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. The permittee is 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.
Other Proposed Changes to the Previous Permit:
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 fur tlue Storinwater Management Plan have been specified in PartII Section A. More
details regarding secondary containment are provided.
3. Additional tequiteunents fui the Stuunwatet, Pollution Pieventiou Plan have been specified in Part II Section A.
The plan must also be updated annually to include a list of significant spills 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 Exposure Exclusion has been added to this draft permit. If industrial materials and
activities are not exposed to precipitation or runoff as described in 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.

1. Description of industrial activities onsite. Organic Specialty Chemical Plant. Make over 200 different products
from Soap, bug spray to personal care items.
2. Do you have a list of all chemicals and materials stored outside? See attached.
3. How was the NOV from Jame 17, 2008 followed up? Did you identify what the illicit discharge from Outfall 006
was? There was a residue in the outfall. The root cause has been fixed. Theproblem was caused when a facility to
make mothballs was restarted and a pump failed. There were cross connections in the piping that have now been
fixed.

Subject: NPDES Stormwater Permit Coverage Renewal
Mount Holly West (MHW) Facility
Permit Number NCS000041
Gaston County
Dear Permittee:
Your facility is currently covered for stormwater discharge under NPDES Permit NCS000041. This
permit expired on May 31, 2008. To assure consideration for continued coverage under your individual
permit, you must apply to the Division of Water Quality (DWQ) for renewal of your permit. Enclosed
you will find an individual permit Renewal Application Form, Supplemental Information request, and
Stormwater Pollution Prevention Plan Certification for your facility.
Filing the application form along with the requested supplemental information will constitute your
application for renewal of this permit. Until your permit renewal is completed and you receive a new
permit, please continue to comply with all conditions and monitoring requirements in your expired
NPDES stormwater permit.
The application and supplement must be completed and returned to DWQ by July 6, 2009. Failure to
request renewal within this time period will result in delay of your permit renewal and may result in a
civil assessment. 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 $25,000 per day.
If you have any questions regarding permit renewal procedures please contact Brian Lowther of the
Stormwater Permitting Unit at (919)-807-6365 or [e-mail].

Subject: NPDES Stormwater Permit Renewal
Clariant Corporation
Permit Number NCS000041
Gaston County
Your facility is currently covered for stormwater discharge under NPDES Permit NCS000041. 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.
If you have any questions regarding the permit renewal procedures please contact Bill Mills of the Stormwater
and General Permits Unit at [phone], ext. 548.
