Central Office Review Summary:
1, Owner's Other Permits: (If applicable)
• No other permits.
2. Ge:ncral Observations: This facility was required to collect a single set of samples in the previous permit. The
parameters were on a list that is not on file. The sampling data raised several questions. The qualitative data was
exactly the same for each inspection.
3. Impairment: Not 303(d) listed. Not addressed in the 2004 Basinwide plan.
4. Threatened and Endangered: NIA. Two species are on the National Heritage map, but neither are T&E.
5. Location: This is in a WS-IV.
6. Industrial Clianges Since Previous Permit: None as of the time the application was submitted.
7. AnaNtieal Monitoring Notes: The analytical requirements reference Form 2F, which is not on file: The
permittee sampled, pl-1, TSS, TN, phosphorus (total phosphorus?), BOD, COD, oil/grease, and nitrogen (is this
nitrate/nitrite nitrogen or TKN because they also sampled TN). The data showed some unexpected results
including:
Page 3 of 8

NCS000385
o Both TN and "nitrogen" were sampled. "Nitrogen" was Found, but TNI was not.
o The data is reported as a range for two outfalls. I have assumed that one sample was taken at each
outfall, and that the range indicates the value found at one and then the other,
o BQD is very low.
o Why did we make theta sample for nutrient, oil/grease, and oxygen -related parameters in the previous
permit? The values were all eery low for everything except pH (which was too low). There is nothing
in the file that indicates that so much sampling is necessary.
8. Qualitative Monitoring Notes: Qualitative monitoring did not show any signs of contamination, but each one
said exactly the same thing. Ensure that the pennittee knows what to look for.

Revised Permit Recommendations: Analytical Monitoring:
. TN, phosphorus, BOD, COD, oil/grease, and nitrogen have been removed from the sampling requirements.
TSS and pH sampling have been maintained.
2_ All analytical monitoring has been set to semi-annually during a representative storm event as defined in Part Il
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 stonnwater 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 teen 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 fol low the Tier 2 guidelines which require a repetition
of the steps I fisted 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 lI 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 I 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 pennit, however.)
T 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 for the Stonmvater Management Plan have been specified in Part II Section A, Nlore
details regarding secondary containment are provided_
3. Additional requirements for the Stormwater Pollution Prevention Plan 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 a semi-annual Ii acility Inspection Program of the site's stormwater
management controls as specified in Part 11 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 § 12226(g), the facility may
qualify for a No Exposure Exclusion from NPDES stonnwater discharge permit requirements. Additional
information is provided in Part I Section A_

Discussions with perinittee: Debbie Clay, 704.862.5000
Update Contact to Jill Ryan, 847-468-7752 contacted 07/25/08
1. Your application indicates that you haven't had any significant changes. Have there been any significant
changes onsite since submitting your application?
ANSWER: Currently adding onto the site. Building a technical center and will send an update in the
nest few weeks. There is secondary containment on all ofthe storage tanks. (acetone, dirty acetone,
toluene diacetate, liquid nitrogen)
2, Data provided:
a. You have reported a range of values for your sampling, do these numbers indicate the values at outfall I
and outfall 2, respectfully? All of the range values are in the order of least to greatest, which values were
from cash outfall? See below.
b. You have sampled for both "nitrogen" and "total nitrogen". What is "nitrogen" (is it TKN or
nitrate/nitrite?) Why was `nitrogen" detected, and not "total nitrogen"? See below.
c. Are you aware of a holding time for AOD and COD? What holding time did You use? Why was COD not
detected when BOD was? See below.
d. TSS is also very low, how was this sample collected? See below.
e. Was "phosphorus" "total phosphorus"? See below.
f. Is there onsite vehicle maintenance? No
All of the qualitative data are exactly the same. This is unusual. How do you define "clear color", "no
odor", "high clarity", "no floating solids", "no suspended solids", "no foam", and "no oil sheen"?
Typically, we see sore variation in the qualitative data recorded over time. A: There was no differciice
observed.
h. ANSWER: New contact not sure about the specifics of the monitoring. Drainage is just from the roof and
parking lot. When asked about the monitoring Jill Ryan talked about how the stonnwater was only from
the roof and parking lot and not sure about the actual values. No changes in the qualitative monitoring
because of there being no visual differences.
3. What is your SIC Code?
a. ANSWER: 2593 or 2899 (http://oaspub.e2a.aov/eiiviro/mtiItisys2.get_list?facilitv�uin=l 10006070946,)
The parent company in Elgin, IL has an SIC code of 285 L Jill Ryan thought the number was 2852 but wasn't
sure and was going to look it up.

Central Office Review Summary:
I . Owner's Other Permits: (If applicable)
• No other permits.
2. General Observations: This facility was required to collect a single set of samples in the previous permit. The
parameters were on a list that is not on file. The sampling data raised several questions. The qualitative data was
exactly the same for each inspection,
3. Impairment: Not 303(d) listed. Not addressed in the 2004 Basinwide plan.
4, Threatened and Endangered-. N/A. Two species are on the National Heritage map, but neither are T&E.
5, Location: This is in a WS-IV.
G. Industrial Changes Since Previous Permit: None as of the time the application was submitted.
Analytical Monitoring Notes: The analytical requirements reference Form 217, which is not on file;. The
permittee sampled, pH, TSS, TN, phosphorus (total phosphorus?), BOD, COD, oil/grease, and nitrogen (is this
nitratelnitrite nitrogen or TKN because they also sampled TN). The data showed some unexpected results
including:
Page 3 of 8

NCS000385
0 Both TN and "nitrogen" were sampled. "Nitrogen" was found, but TN was not.
o The data is reported as a range for two outfalls. 1 have assumed that one sample was taken at each
outfall, and that the range indicates the value found at one and then the other.
o BOD is very low.
o Why did we make them sample for nutrient, oil/grease, and oxygen -related parametcrs in the previous
permit? The values were all very low for everything; except pH (which was too low). "There is nothing
in the file that indicates that so much sampling is necessary.
S. Qualitative Monitoring. Notes: Qualitative monitoring did not show any signs of contamination, but each one
said exactly the same thing. Ensure that the permittee knows what to look for.

hours in which no storm event measuring greater than 0A inches has occurred.

_Best Management Practices
DSM Desotech, Stanley, NC
Due to our closed loop system design of solvent cleaning and insignificant volume/type
of air emissions; the Stanley site is exempt from an Air Permit. As we consider new
materials, we evaluate them using a new raw material introduction process. This includes
an environmental discussion as it relates to air quality and emissions reporting, especially
VOC, HAP and particulate.
With virtually no process water usage, we are exempt from it Wastewater Permit.
We sample stormwater at two on -site outfalls as detailed under our Stormwater Permit
for visual and odor characteristics only. We perform routine environmental audits of the
facility grounds to look for surface contaminants or soil erosion that may affect our
sfrormwater quality. No exceptions have been documented.
All of our chemical storage tanks and tanker unloading areas are diked and rainwater is
sampled prior to pumping and.release.
In 2005, we have reduced our chemical waste by 13%o from 2004 levels. We monitor our
satellite collection sites and remote accumulation site daily along with complying with all
RCRA requirements. Documentation records are kept that indicates legal compliance
issues (closed and undamaged containers, proper label inglidentification, LOPC, ctc)
along with general safety and housekeeping,
We welcome local emergency personnel on -site for a walkthrough and discussion oil t1i n
m
support needed in emergency situations. The fire department and rescue squad family r>
themselves with the facility layout and location of emergency equipment and chemicaf��'
storage. We conduct at least annually as refresher and also for newcomers. The inn � Fill,
comments we receive are very positive, as we are praised as one of the few businesses n
who allow such open communication.
We allow the Police Department to use our conference room facilities and presentation I� l
equipment for departmental meetings.
Our site has not had a recordable incident or illness since we relocated to Stanley NC in
2001. We attend the annual North Carolina Department of Labor Safety Awards Banquet
annually. The Stanley site has been awarded this recognition for eight (8) consecutive
years. The local newspaper attends and publishes an article with the recipient
information.
We are a Responsible Care® site as a member of' the American Chemistry Council and
have submitted our Security Vulnerability Assessment for review by a local third party.

We have completed HAZOP studies on all storage and transfer process equipment before
design acceptance. Our piping and product transfer is a closed loop system controlled by
Delta V integrated computer software
All tank flanges and ports are above chemical level (top of tank) Pressure/flow variations
result in immediate alarm in control room. Operators are always present during tanker
unloading and can stop transfer immediately if needed
r
We receive many visitors to the facility to inquire about employment with us. Many
comment that they have heard positive remarks regarding the cleanliness and aesthetic
appeal of the facility along with the
Quality and effectiveness of other License to Operate initiatives such as
technical and behavioral proiects
We have developed a partnership with Gaston Community College on an employee
development program. Required and optional courses will be offered to ensure that we
maintain a competent and trained workforce, along with providing opportunities for
career growth.
A Contractor Assessment progrinnn has been developed and contractor evaluations are
required prior to hire, along with conducting periodic assessments of contractor
performance. The assessment process involves a cross-section team who provide
challenges and feedback. The goal is to ensure that we maintain competent and safety -
minded contractor personnel, and that a quality service is provided.
The SHE mentorship program offers associates to become a "trained trainer" in safety
related topics, so that they can provide required training to others. Under the direction of
the SFIEQ Manager, this training not only provides awareness and participation 11•onn the
operations level, the Safety Program is owned by many and not .just a few.
The Stanley facility produced a professionally engineered SHE orientation video utilizing
our own associates explaining and demonstrating emergency response alarms and
protocol, proper PPE, safe handling of chemicals, and other subjects as part of the Basic
SHE course material. This video is a required part of the SHE orientation for visitors;
contractors and new associates.

Revised Permit Recommendations: Analytical Monitoring:
1. TN, phosphorus, BOD, COD, oil/grease, and nitrogen have been removed from the sampling requirements.
TSS and pH sampling have been maintained.
2. All analytical monitoring has been set to semi-annually during a representative storm event as defined in Part 11
Section 6. 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. Exceedanees 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 I 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 I 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 11 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 i 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 fist 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 Stonnwater Management Plan have been specified in Part II Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the Stornnwater Pollution Prevention Plan have been specified in Part it 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.
S. information regarding the No Exposure Exclusion has been added to this draft permit. I f industrial materials
and activities are not exposed to precipitation or runoff as described in 40 CFR § I22.26(g), the facility may
qualify fbr.a No Exposure Exclusion from NPDES stormwater discharge permit requirements. Additional
information is provided in Part I Section A.

and outfall 2, respectfully? All of the range values are in the order of least to greatest, which values were
from each outfall? See below.
b. You have sampled for both "nitrogen" and "total nitrogen". What is "nitrogen" (is it TKN or
nitrate/nitrite?) Why was "nitrogen" detected, and not "total nitrogen"? See below.
c. Are you aware of a holding time for BOD and COD? What holding time did you use? Why was COD not
detected when BOD was? See below.
d. TSS is also very low, how was this sample collected? See below.
e. Was "phosphorus" "total phosphorus"? See below.
f. Is there onsite vehicle maintenance? No
g. All of the qualitative data are exactly the same. This is unusual. How do you define "clear color", "no
odor", "high clarity", "no floating; solids", "no suspended solids", "no foam", and "no oil sheen"?
Typically, we see some variation in the qualitative data recorded over time, A: There was no difference
observed.
h. ANSWER: New contact not sure about the specifics of the monitoring. Drainage is just from the roof and
parking lot. When asked about the monitoring Jill Ryan talked about how the stonnwater was only from
the roof and parking lot and not sure about the actual values. No changes in the qualitative monitoring
because of there being no visual differences.
3. What is your SIC Code?
a. ANSWER: 2893 or 2899(http://oaspu,b.epa.aovlenviro/multisys2.�Jet list?facility uin=110006070946)
The parent company in Elgin, IL has an SIC code of285I . Jill Ryan thought the nu«iber «las 2852 but wasn't
sure and was going to look it up.

manufacturing or fueling operations by permanent or semi -permanent covers. 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 Superfund Amendments and Reauthorization Act (SARA)
water priority chemicals; and storage in any amount of hazardous substances 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, and shall record the volume capacity of
each tank and containment area. If the secondary containment devices are
connected directly 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,
outfali 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 the material stored within the containment area. Records
documenting the individual making the observation, the description of the

Permit No. NCS000385
accumulated stormwater and the date, and time of the release shall be kept for a
period of five (5) years.
C. BMP Summary. A narrative description shall be provided of Best Management
Practices (BMPs) to be considered such as, but not limited to, diversion structures,
secondary containment structures, oil and grease separation, debris control,
vegetative filter strips, infiltration and stormwater detention or retention, where
necessary. The need for structural BMPs shall be based on the assessment of the
potential of pollutant sources to contribute significant quantities of pollutants to
stormwater discharges and data collected through monitoring of stormwater
discharges.
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 team) responsible for implementing the
SPRP shall be identified. A responsible 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 S.PCC,plan-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 Maintenancc.and\G'aod'Housekeeping Program. A preventative
maintenance program shall be developed. The program shall document schedules of
inspections and maintenance activities of stormwater control systems, plant equipment
and systems. inspection•of.material handling areas and regular cleaning schedules of
these areas shall be incorporated into the program. The program shall specifically
identify industrial areas that have the potential for soil erosion, and must specifically note
the preventative BMP or maintenance activity implemented in the areas, and must include
regular inspections of the areas.
5_ Employee Training. Training schedules shall be developed and training provided at a
minimum on an annual basis on proper spill response and cleanup procedures and
preventative maintenance activities for all personnel involved in any of the facility's
operations that have the potential to contaminate stormwater runoff. Facility personnel
(or team) responsible for implementing the training shall be identified.
6. Responsible Party. The Stonnwater 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 that has a significant effect on the
potential for the discharge of pollutants to surface waters. The Stormwater Pollution
Prevention Plan shall be reviewed and updated on an annual basis. The annual update
Part 11 Page 3 of 10

Permit No. NCS000385
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
re -certification thai the stormwater outfalls have been evaluated for the presence of non-
stormwater discharges.
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
submit a time schedule to the Director for modifying the Plan to meet minimum
requirements. The permitter shall provide certification in writing (in accordance with
Part III, Standard Conditions, Section B, Paragraph 3) to the Director that the changes
have been made.
8. facility Inspection Program. Inspections of the facility`and all stormwater systems shall
occur at a minimum on a semi-annual schedule, onceduring the -first half of the year
(January through June) and once during the secon0alf(July-through December), with at
least 60-days separating inspection dates (unless performed- m0re frequently). The
inspection and any subsequent maintenance activities,performed shall be documented,
recording date and time of inspection, indiviiival(s),making the inspection and a narrative
description of the facility's stormwater control,systems, plant equipment and systems.
Records of these inspections shall be,incorporate-d into the Stormwater Pollution
Prevention Plan. These facility inspections aree different from, and in addition to, the
stormwater discharge characteristic monitoring required in Part II of this permit.
9. Implementation. The permittee shall,iinplement the Plan. The permittee shall document
all monitoring, measurements, inspections and maintenance activities and training
provided to employcest including the log of the sampling data and of actions taken to

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 often 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
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.

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 (USGS 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
stormv,later 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.
(b) A nar-native description of storage practices, loading and unloading activities.
outdoor process areas, dust or particulate generating or control processes. and
waste disposal practices.
(c) A site map dra%vn to scale with the distance legend indicating location of
industrial activities (including storage of materials. disposal areas. process areas
and loadM2 and unloading areas). drainage structures. drainage areas for each
outfall and activities occurring in the drainage area, building locations. existing
BMPs and impervious surfaces, and the percentage of each drainage area that is
impervious. For each outfall_ a narrative description of the potential pollutants
which could be expected to be present in the stormwater discharge-
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the 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

the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. Wherever practical, the per7nittee 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 Schedule. A schedule to provide secondary containment
for bulk storage of liquid materials, storage of Section 313 of Title I11 of the
Stsperfund Amendments and Reauthorization Act (SARA) water priority
chemicals, or storage of hazardoiis substances to prevent leaks and spills from
contaminating stormwater runoff. If the secondary containment devices are
connected directly to ston-nwater conveyance systems. the connection shall be
controlled by manually activated valves or other similar devices [which shall be
secured 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 the material stored within the containment area. Records
documenting the individual making the observation. the description of the
accumulated stormwater and the date and time of the reiease shall be kept for a
period of five years.
(C) BivlP Summary. A narrative description shall be provided of Best Management
Practices (BMPs) to be considered such as. but not limited to, oil and grease

inventory of the facility. Facility personnel (or team) responsible for implementing the
SPRP shall be identified..A responsible 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, a SPCC plan 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 program shall be developed. The program shall document schedules of
inspections and maintenance activities of stormwater control systems, plant equipment

SECTION C: QUALITATIVE MONITORING REQUIREMENTS
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status and shall be performed as specified below in Table 1. Qualitative
monitoring is for the purpose of evaluating the effectiveness of the Stormwater Pollution
Prevention Plan (SPPP) and assessing new sources of stormwater pollution. No analytical tests
are required. Qualitative monitoring of stormwater outfalls does not need to be performed during
a representative storm event.
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 Stormwater Pollution Prevention
Plan.
All qualitative monitoring will be performed twice per year, once in the spring (April - June) and
once in the fall (September - November).

stormwater discharges. The certification statement will be signed in accordance with
the requirements found in Part 111, Standard Conditions, Section B, Paragraph 3. The
permittee shall re-certify.annually that the stormwater'outfails have been evaluated
for the presence of non-stormwater discharges.
2. Stormwater Management Plan. The stormwater management plan shall contain a
narrative description of tile' materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural rncasures: The stormwater management plan, at a minimum, shall
incorporate the following;:
a. I"easibility 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 perill ittee shall
prevent exposure of all storage. areas, material handling operations, and
manuracturing or fueling operations by permanent or semi -permanent covers. 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 Requiremchts and Records. Secondary containment is
required for: .bulk storage of liquid materials; storage in any amount of Section
3.13 of Title lit of the Superfund Amendments and Reauthorization Act (SARA)
water priority chemicals; and storage in any amount of hazardous substances to
prevent leaks and spills from contaminating; stonnwater runoff. A table or
summary of all such tanks and stored materials and their associated secondary
containment areas shall be maintained, and shall record the volume capacity of
each tank and containment area. If the secondary containment devices are
connected directly 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 aceumulatcs
in the containment area shall be at a mininuun visually observed for color, roam,
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 the material stored within the containment area. Records

period of five (5) years.
C. BMP Summary. A narrative description shall be provided of Best Management
Practices (BMI's) to be considered such as, but not limited to, diversion structures,
secondary containment structures, oil.and grease separation, debris control,
vegetative filter strips, inlfiltration and stormwater detention or retention, where
necessary. The need for structural BMPs shall be based on the assessment of the
potential of pollutant sources to contribute significant quantities of pollutants to
stormwater discharges and data collected through monitoring of stormwater
discharges.
Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPIZI')
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or team) responsible for implementing the
SPRP�shall be identified. A responsible 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 SPCC plan 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 program shall be developed. The program shall document schedules of
inspections and maintenance activities of stonnwater control systems, plant equipment
-and systems. Inspection of Material handling areas and regular cleaning schedules of
these areas shall be incorporated into the program. The program shall specifically

the preventative 13MP or maintenance activity implemented in the areas, and must include -
regular inspections of the areas.
5. Employee Training. Training schedules shall be developed and training provided at a
minimum on an annual basis on proper spill response and cleanup'procedures and
preventative maintenance activities for all personnel involved in any of the facility's
operations that have the potential to contaminate stormwater runoff facility personnel
(or team) responsible for implementing -the training shall be identified.
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 that has a significant effect on the
potential far the discharge of pollutants to surface waters. The Stormwater Pollution
Prevention PIan shall be reviewed and updated on an annual basis. The annual update

Pcrmit No. NCS000385
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
re -certification that the stormwater outfalls have been evaluated for the presence of non-
stormwater discharges.
The Director may noti fy 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
submit a time schedule to the Director for modifying the flan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part I11, Standard Conditions, Section B, Paragraph 3) to the Director that the changes
have been made. :
S. •. facility Inspection Program. Inspections of the facility and all stormwater systems shall
occur at a minimum al a serni-annual schedule, once during the first half of the year
(January through June) and once during; the second half (July through December), with at
least 60-days separating inspection dates (unless performed more frequently). The
inspection and any subsequent maintenance activities performed shall be documented,
recording date and time of inspection, individual(s) making the inspection and a narrative
description of the facility's stormwater control systems, plant equipment and systems.

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 rcquired
n-tonitoring will result in a minimum of ten analytical samplings being conducted over the terns 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 consecutivehours 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. i

Qualitative monitoring requires a visual inspection'of each stormwater outfall reggardless of
representative outfall status and shall be performed as speci Lied in Table 4, during the analytical
monituring event. Qualitative monitoring is for the,purpose of evaluating; the effectiveness of the
Stormwater Pollutim Prevention flan (SPPP) and assessing new sources of stormwater pollution.
Pranalytical monitoring is not required, the permittee still Must CondUCt sellll-atlllual qualitative
monitoring.
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.

measurement of flow at 20 minute intervals during the rainfall event.
32. Total Maximum Daily Load (TMDL)
A TMDL is a calculation of the maximum amount of a pollutant that a waterbody can receive and still mcet
water quality standards, and an allocation of that amount to the pollutant's sources. A TMDL is a detailed
water quality assessment that provides the scientific foundation for an implementation plan. The
implementation plan outlines the steps necessary to reduce pollutant loads in a certain body of water to
restore and maintain water quality standards in all seasons. The Clean Water Act, Section 303, establishes
the .eater quality standards and "TMDL programs.

Permit No. ,NCS000385
DSM Desotech Incorporated
Gaston County
Dear Mr. Nack:
Enclosed with this letter is a copy of the draft stormwater permit for your facility. PIease 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: .
I., The analytical monitoring parameters, TN, phosphorus, BOD, COD, oil/grease, and nitrogen, have been
removed from the sampling requirements in this permit, TSS and pH sampling have been maintained.
2. pH has been added to the analytical monitoring requirements.
3. All analytical monitoring has been set to semi-annually during a representative storm event as defined in
Part 11 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.
4. 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.
5. You are required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part 1I Section B. Qualitative monitoring is required regardless of
representative outfall status.
6. You are responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1, 4,
and 5.
7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall
parameter is in this permit, however.) No°ihCarolina

8. Vehicle main tenance 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 ch tinges:
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 I1 Section A.
More details �regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention 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.
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.

Dear Mr. Shaw:
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. The analytical monitoring parameters, BOD-5, COD, and pH, have been maintained for the sampling
requirements in this permit. Acetone was removed. TSS was added to the analytical monitoring
requirements based on EPA Multi -Sector General Permit, Sector C "Chemical and Allied Products"
recommendations.
2. pl-i has been added to the analytical monitoring requirements.
3. All analytical monitoring has been set to semi-annually during a representative storm event as defined in
Part It 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.
4. 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.
5. 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.
6. You are responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1, 4,
and 5. OptihCarol

7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall
parameter is in this permit, however.)
8. 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 11 Section A.
More details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part I1
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.
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 -

Central Office Review Summary:
I. Owner's Other Permits: (if applicable)
• No other permits.
2. General Observations: This facility was required to collect a single set of samples in the previous permit. The
parameters were on a list that is not on file. The sampling data raised several questions. The qualitative data was
exactly the same for each inspection.
3. Impairment: Not 303(d) listed. Not addressed in the 2004 Basinwide plan.
4. Threatened and Endanuered: NIA. Two species are on the National Heritage map, but neither are T&E.
5, Location: This is in a WS-IV.
6. industrial Changes Since Previous Permit: None as of the time the application was submitted.
7, Analytical Monitoring: The analytical regUirerIIents reference Form 2F, which is not on file. The
permittee sampled, pl-I, TSS, TN, phosphorus (total phosphorus'?), BOD, COD, oil/grease, and nitrogen (is this
nitrate/nitrite nitrogen or TKN because they also sampled TN). The data showed some unexpected results
including:
Page 3 of 8

Nvcsoa0385
r
o Both TN and "nitrogen" were sampled. "Nitrogen" was found, but TNI was not.
c The data is reported as a range for two outfalls. I have assumed that one sample was taken at each
outfall, and that the range indicates the value found at one and then the other.
o BQD is very low.
o Why did we make thern sample for nutrient, oillgrease, and oxygen -related parameters in the previous
permit? The values were all very lore for everything except pH (which was too low). There is nothing
in the file that indicates that so mELch sampling is necessary.
S. Qualitative ti-lonitoring Notes: Qualitative monitoring did not show any signs of contamination, but each one
said exactly the same thing_ Ensure that the permittee knows what to look for.

Revised Permit Recommendations: Analytical !Monitoring:
I . TN, phosphorus, BOD, COD, oil/grease, and nitrogen have been removed from the sampling requirements.
TSS and pl•I sampling have been maintained.
2. All analytical monitoring has been set to semi-annually during a representative storm event as defined in Part 11
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 Flory" 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 tent. 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 santl)les during
representative storm events as defined in Part 11 Section B. Quatitative roimOnng is required regardless of
representative outfall status.
5. The permittee is responsible for all monitoring until the renewal permit is issued. See Footnote I of Tables 1,
4, and 5.
6. The flow reporting requirement has been rernoved per DWQ revised strategy. (The total rainfall parameter is in

7. Vehicle main}tenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Other Propose(] 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 TVIDL 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 anti also must certify that the oudalls have been in to
ensure that they do not contain non-stormwater discharges. Additional information is provided in Part 11
Section A.
1 additional requirements for the Stormwater Management Plan have been specified in Part 11 Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part lI 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. 'Che facility must now imp:ement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part lI Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial materials

Discussions with permittee: Debbie Clay, 704.S62.5000
Update Contact to Jill Ryan, 347-465-7752 contacted 07/25/03
1, Your application indicates that you haven't had any significant changes. Have there been any significant
changes onsite since submitting your application?
a. ANSWER: Currently adding onto the site. Building a technical center and will send an update in the
next few weeks. There is secondary containment on all of the storage tanks. (acetone, dirty acetone,
toluene diacetate, liquid nitrogen)
2. Data provided:
a, You have reported a range of values for your sampling, do these numbers indicate the values at outfall l
and outfali 2, respectfully? All of the range values are in the order of least to greatest, which values were
from each outfall? See below.
b. You have sampled for both "nitrogen" and "total nitrogen". What is "nitrogen" (is it TKN or
nitrate/nitrite?) Why was "nitrogen" detected, and not "total nitrogen"? Sze below.
c. Are you aware of a holding time for BOD and COD? What holding time (lid you use? Why was COD not
detected when BOD was? See below.
d. TSS is also very low, how was this sample collected? See below.
e. Was "phosphorus" "total phosphorus"? See below.
f. Is there onsite vehicle maintenance? No
g. All of the qualitative data are exactly the same. This is unusual. How do you define "clear color", "no
odor", "high clarity", "no floating solids", "no suspended solids", "no foam", and "no oil sheen"?
Typically, we see some variation in the qualitative data recorded over time. A: There was no difference
observed.
h. ANSWER: New contact not sure about the specifics of the monitoring. Drainage is just from the roof and
parking lot. When asked about the monitoring Jill Ryan talked about how the stormwater was only from
the roof and parking lot and not sure about the actual values_ No changes in the qualitative monitoring
because of there being no visual differences.
a. What is your SIC Code?
a. ANSWER: 2893 or 2899 (hap://caspub. epa,gov/envirclnzuItis.2get list?facility uin--1 10006070946)
The parent company in Elgin, IL has an SIC code of2851. Jill Ryan thought the number was 2852 but wasn't
sure and was going to look it up.

CentraI Office Review Summary;
1. Owner's Other Permits: (If applicable)
• No other permits.
2. General Observations: This facility was required to collect a single set of samples in the previous permit. The
parameters were on a list that is not on file. The sampling data raised several questions. The qualitative data was
exactly the same for each inspection.
3. ]mpainnent: Not 303(d) listed, Not addressed in the 2004 Basinwide plan.
4. Threatened and Endangered: NIA. Two species are on the National Heritage map, but neither are T&E.
5. Location: This is in a WS-IV.
b. Industrial Changcs Since Previous Permit: None as of the time the application was submitted.
7. Analytical Monitoring Notes: The analytical requirements reference Form 2F, which is not on file. The
permittee sampled, pH, TSS, TN, phosphorus (total phosphorus?), BOD, COD, oil/grease, and nitrogen (is this
nitrate/nitrite nitrogen or TKN because they also sampled TN). The data showed some unexpected results
including:
Page 3 of 8

NCS000385
o Both TN and "nitrogen" were sampled. "Nitrogen" was found, but TN was not.
o The data is reported as a range for two outfalls. I have assumed that one sample was taken at each
outfall, and that the range indicates the value found at one and then the other.
o BOD is very low.
o Why did we make them sample for nutrient, oil/grease, and oxygen -related parameters in the previous
permit? The values were all very low for everything except pH (which was too low). There is nothing
in the file that indicates that so much sampling is necessary.
8. Qualitative Monitorin J Notes: Qualitative monitoring did not show any signs of contamination, but each one
said exactly the sanie thing. Ensure that the permittee knows what to look for.

Revised Permit Recommendations: Analytical Monitoring:
l . TN, phosphorus, BOD, COD, oil/grease, and nitrogen have been removed from the sampling requirements.
TSS and pH sampling have been maintained.
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 an 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 I 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 I of Tables 1,
4, and 5.
6. The now 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 for the Stormwater Management Plan have been specified in Part II Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan 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 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. I f 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.

Discussions with perinittee: Debbie Clay, 704.862.5000
Update Contact to Jill Ryan, 847-468-7752 contacted 07/25/08
1. Your application indicates that you haven't had any significant changes. Have there been any significant
changes onsite since submitting your application?
a. ANSWER: Currently adding onto the site. Building a technical center an'd will send an update in the
next few weeks. There is secondary containment on all of the storage tanks. (acetone, dirty acetone,
toluene diaceiate, liquid nitrogen)
2. Data provided:
a. You have reported a range of values for your sampling, do these numbers indicate the values at outfali I
and outfail 2, respectfully? All of the range values are in the order of least to greatest, which values were
from each outfall? See below.
b. You have sampled for both "nitrogen" and "total nitrogen". What is "nitrogen" (is it TKN or
nitrate/nitrite?) Why was "nitrogen" detected, and not "total nitrogen"? See below.
c. Are you aware of a holding time for BOD and COD? What holding time did you use? Why was COD not
detected when BOD was? See below.
d. TSS is also very low, how was this sample collected? See below.
e. Was "phosphorus" "total phosphorus"? See below.
f. Is there onsite vehicle maintenance? No
g. All of the qualitative data are exactly the same. This is unusual. How do you define "clear color", "no
odor", "high clarity", "no floating solids", "no suspended solids", "no foam", and "no oil sheen'?
Typically, we see some variation in the qualitative data recorded over time. A: There was no difference
observed.
h. ANSWER: New contact not sure about the specifics of the monitoring. Drainage is just from the roof and
parking lot. When asked about the monitoring Jill Ryan talked about how the stormwater was only from
the roof and parking lot and not sure about the actual values. No changes in the qualitative monitoring
because of there being no visual differences.
3. What is your SIC Code?
a. ANSWER: 2893 or 2899 (http://oaspub.epa.gov/enviro/multisys2.get lis0facility uin=1 I000607094b)
The parent company in Elgin, IL has an SIC code of 2851. Jill Ryan thought the number was 2852 but wasn't
sure and was going to look it up.
