Subject: Draft NPDES Stormwater Permit
Permit No. NCS000057
Chemical Specialties, Inc. (CSI)
Cabarrus County
Dear Mr. Dwyer:
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 have been reduced in this permit to include TSS, COD, Copper, Zinc, and
pH. Sampling for Arsenic and Lead have been removed.
2. All analytical monitoring remains at semi-annually during a qualifying storm event However, the qualifying
storm event has been revised from a representative storm event to a measurable 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. Failure to monitor semi-annually per permit terms immediately institutes monthly monitoring for all
stormwater parameters for six months, as specified in below Table 2.
4. Benchmarks for analytical monitoring remain in this draft permit Exceedances of benchmark values require
the permittee to increase monitoring, increase management actions, increase record keeping, and/or instals
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 One 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 Two guidelines which require a
repetition of the steps listed for Tier One and also immediately institute monthly monitoring for all
parameters at every outfall where a sampling result exceeded the benchmark value for two consecutive
samples. During the term of this permit, if the valid sampling results required for the permit monitoring
periods exceed the benchmark value, or are outside the benchmark range, for any specific parameter at any
specific outfall on four occasions, the permittee shall follow the Tier Three'guidelines which require the
permittee to notify the DWQ Regional Office Supervisor in writing within 30 days of receipt of the fourth
analytical results.

Permit No. NCS000057
5. As discussed previously, Copper and Zinc are not subject to triggering the increased monitoring requirements
of Tier Two and Three. In lieu of this, mandatory best management practices (BMPs) are included as
specified in Part I1, Section E.
6. You are required to collect all of the analytical and qualitative monitoring samples during measurable storm
events as defined in Part II Section B. Qualitative monitoring is required regardless of representative outfall
status.
7. A section on qualitative monitoring response has been added in Part II, Section C, which is similar to the Tier
Three for analytical monitoring, for repeatedly failing to respond effectively to correct problems identified by
qualitative monitoring, or if the discharge causes or contributes to a water quality standard violation.
8. You are responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 2, 4, and 5.
9. The event duration requirement has been removed per DWQ revised strategy. (The total rainfall parameter is
in this permit, however.)
10. Vehicle maintenance monitoring remains semi-annually in order to coincide with analytical and qualitative
monitoring. Monitoring for TPH has replaced Oil & Grease. 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 TMD[, 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 Parti1 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 Il 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. 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.
5. In addition to submitting two signed copies of DMRs to Central Files, a separate signed Annual Summary DMR
copy must be submitted to the local DWQ Regional Office by March 1 of each year.
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.
If you have any questions or comments concerning this draft permit, contact me at [phone] or
[e-mail].

3. 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. Faciiity personnel 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 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. n
4. Preventative Maintenance and Good House ep' gr . A preventative
maintenance and good housekeeping program e e ed and implemented.
The program shall list all stormwater control s s, stormwater discharge outfalls, all
on -site and adjacent surface waters and wed ds, trial activity areas (including

structural BMPs. The program all b h edules of inspections, maintenance,
and housekeeping activitie f sto at I trol systems, as well as facility
equipment, facility areas, i gtems that present a potential for stormwater
exposure or stormwater poll not already addressed under another element
of the SPPP. Inspection o ater ndling areas and regular cleaning schedules of
these areas shall be inc orate to the program. Timely compliance with the
established schedules f 'nsp ions, maintenance, and housekeeping shall be
recorded and maintainglEWe SPPP.
5. Employee Training. Training programs shall be developed and training provided at a
minimum on an annual basis for facility personnel with responsibilities for: spill
response and cleanup, preventative maintenance activities, and for any of the facility's
operations that have the potential to contaminate stormwater runoff. The facility
personnel responsible for implementing the training shall be identified, and their
annual training shall be documented by the signature of each employee trained.
6. Responsible Party. The SPPP shall identify a specific position or positions responsible
for the overall coordination, development, implementation, and revision of the SPPP.
Responsibilities for all components of the SPPP shall be documented and position
assignments provided.
7. SPPP Amendment. The permittee shall amend the SPPP whenever there is a change in
design, construction, operation, site drainage, maintenance, or configuration of the
physical features which may have a significant effect on the potential for the discharge
of pollutants to surface waters. All aspects of the SPPP shall be reviewed and
updated on an annual basis. The annual update shall include:

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1.
All analytical monitoring shall he performed during a measureable storm event at each
stormwater discharge outfall (SDO).
A measurable storm event is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a
shorter interval is representative for local storm events during the sampling period, and the
permittee obtains approval from the local DWQ Regional Office. See Definitions,

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

Permit No. NCS000057
SECTION C: QUALITATIVE MONITORING REQUIREMENTS
The purpose of qualitative monitoring is to evaluate the effectiveness of the Stormwater
Pollution Prevention Plan (SPPP) and assess new sources of stormwater pollution.
Qualitative monitoring of stormwater outfalls must be performed during a measurable
storm event.
Qualitative monitoring requires,a visual inspection of each stormwater outfall regardless of
representative outfall status. Qualitative monitoring shall be performed semi-annually as
specified in Table 4, and during required analytical monitoring events (unless the permittee
is required to perform further qualitative sampling per the Qualitative Monitoring
Response, below). Inability to sample due to adverse weath conditions must be
documented in the SPPP and recorded on the DMR (fee jar
rsA' Ave Weather in Definitions).
In the event an atypical condition is noted at a sto ter �ge outfall, the permittee
shall document the suspected cause of the co nditio any actions taken'in response to
the discovery. This documentation will be main e the SPPP.

monitoring throughout the permit renewal process until a new permit is issued.
2 Monitoring Location: Qualitative monitoring shall be performed at each stormwater discharge outfall
(SDO) regardless of representative outfall status.
A minimum of 60 days must separate monitoring dates, unless additional sampling has
been instituted as part of other analytical monitoring requirements in this permit.
Part 11 Page 9 of 12

Permit No. NCS0000S7
If the permittee's qualitative monitoring indicates that existing stormwater BMPs are
ineffective, or that significant stormwater contamination is present, the permittee shall
investigate potential causes, evaluate the feasibility of corrective actions, and implement
those corrective actions within 60 days, per the Qualitative Monitoring Response, below.
A written record of the permittee's investigation, evaluation, and response actions shall be
kept in the Stormwater Pollution Prevention Plan.
Qualitative monitoring is for the purposes of evaluating SPPP effectiveness, assessing new sources
of stormwater pollution, and prompting the permittee's response to pollution. If the permittee
repeatedly fails to respond effectively to correct problems identified by qualitative monitoring, or if
the discharge causes or contributes to a water quality standar violation, DWQ may but is not
limited to:
• require that the permittee revise, increase, c

SECTION E: MANDATORY BEST MANAGEMENT PRACTICIES (BMPS)
The Permittee shall implement the following BMPs at this facility and shall include these
BMPs in the facility's SPPP:
1. The Permittee shall ensure entryways and loading/unloading areas near
manufacturing areas where copper and zinc exposure could occur are swept and
cleaned -up daily, and that'cleaning procedures are conspicuously posted within the
affected work areas.
2. The Permittee shall ensure routine evaluations by employee task groups of BMPs
intended to reduce copper and zinc exposure and shall identify practices or areas in
need of improvement.
Part 11 Page 11 of 12

Permit No. NCS000057
3. The Permittee shall implement BMPs to reduce copper and zinc exposure, including
but not limited to: storing empty drums and totes indoors; improving preventative
maintenance for any dust collectors; and clean-up from handling and storing of the
powdered, liquid, and scrap copper and zinc materials. For BMPs that have already
been implemented, the Permittee shall ensure those practices are maintained as
long as they effectively reduce copper and zinc exposure.
4. The Permittee shall devise a Monitoring Plan for sampling runoff from segregated
areas (for example, the roof drains and loading/unloading areas) to determine
where the primary contributions of copper and zinc to stormwater occur at the site.
The permittee may also include performing upstream and downstream monitoring
during rain events of the receiving stream to help ide ify to what extent the facility
may be contributing to the stream's impairm nt pper. This Monitoring Plan
shall be submitted to DWQ for review and � ro in ur months of the
effective date of this permit [by Septem , 20 a Monitoring Plan should
require sampling (grab samples) be conduc d ring measurable storm events. In
addition to other parameters the Permitt de seful, the Permittee shall
analyze copper and zinc concentrati0 e i e flow volume for each sampled
event. If averages will be used, the n o chide criteria about how many
samples are required. If the Perm' a ill aluate the proportion of contribution
to the total mass of cop@& an c i ff from the entire site, measurements
should be taken concu mwater discharge outfalls. Revisions to the
Monitoring Plan shall no a vision to the Stormwater Permit. Any revision
of the Monitoring Pla ter t , itial review and approval of DWQ shall be
accomplished by m al agre ent between DWQ and the Permittee.
S. For areas the Permits determined to be primary contributions to copper
and/or zinc in runoff from this facility, either through the above Monitoring Plan or
by other means, the Permittee shall assess BMPs intended to reduce copper and zinc
release and exposure from industrial activities, reduce other sources of copper and
zinc contamination, and/or capture and treat the runoff with engineered controls.
The Permittee shall establish a schedule to implement selected BMPs and shall
submit a status report to DWQ outlining progress two and a half years following
the effective date of this permit [by November 30, 20141. The BMPs assessment
and recommendations may focus on copper and zinc sources attributable to
industrial activities and materials, but the report should list any other influences
that are suspected to, or were determined to, contribute significant amounts of
copper and zinc to the stormwater discharge.

NCS000057 Chemical Specialties, Inc
Cabarrus County
Site inspection conducted on January 19, 2012, by Michael Parker. Facility contact: Ms. Jonna Stein,
Operations Manager, [phone] and Mr. Mark Dwyer, Safety, Health and Environmental
Manager, [phone]. This request is for the renewal of the subject SW permit. This facility is
currently in the business of producing inorganic products for industrial and agricultural applications
and the wood preserving industry. Chemical Specialties (CS) is in the process of switching over to
organic based wood preserving chemicals, which is a trend throughout the wood preserving industry.
The site has two SW outfalls, one which drains to unnamed tributary to the Rocky River and the other
drains to a conveyance channel that empties into the Rocky River (RR). The RR at CS is listed as
impaired for Copper, Turbidity, and Biological Integrity. The downstream segment of the RR is listed
as impaired for Copper, Turbidity, and Zinc.
A small part of the SW generated on the western side of the CS site discharges through a steel pipe into
a conveyance channel located adjacent to the RR. This outfall is designated as outfall 001. On the day
of the site visit, the only flow observed in this pipe was drinking water being used to circulate through
jackets used to keep nearby pieces of machinery from freezing. Outfall 001 receives the least amount
of SW generated at this site and a significant portion of the industrial processes that drain to this outfall
are under roof. Even so, benchmark levels for Cu and Zn are routinely exceeded at this outfall.
Observations made during the site visit noted that there were very limited options for structural BMPs
at this outfall due to the fact the area is almost entirely paved and this part of the site sits very near the
top -of -bank of the RR. The proximity of the RR to the site (and in particular this outfall) is
problematic since storage of raw materials, loading and unloading of raw materials and the finished
product, and the various industrial processes are occurring adjacent to SW collection drains that empty
into this outfall. Major operational changes would be necessary if current operations were shifted to
another portion of the site. CS has made some improvements in this area, and additional measures are
planned.
Part of the SW generated at CS site is routed to an existing treatment lagoon that is covered under a
separate NPDES wastewater permit (NC0006351). There is also a portion of the site's SW that drains
towards the lagoon, but does not enter the lagoon. This SW eventually enters into an intermittent
channel (both by point and non -point means) that originates onsite and eventually discharges near the
south end of the property into the RR and is designated as outfall 002. On the day of the site visit, the
intermittent channel had substantial flow, even though rainfall had not occurred for at least 48 hours
prior to the site visit. It is surmised that the flow observed in the channel was predominately base flow
from seeps and groundwater sources located upstream. During the site visit, Ms. Stein informed the
writer that analytical testing for this SW outfall was being collected in -channel at an inlet structure
located � 200 feet from the channel's junction with the RR. Based on observations made during the
site visit, any testing performed at this location especially when base flow existed in the channel would
likely not provide data that was entirely reflective of the SW draining from this portion of this facility.

Page Two
Based on the analytical data collected to -date at outfall 002 (and reported to the Division), benchmark
exceedances for Cu and Zinc are numerous. The existence of base flow in the channel, however,
would t dd di W flow, and any data collected would likely not provide an accurate
characte on S draining to this outfall. It is unknown, however, as to .whether the
analytic e t� fo d at this outfall was conducted when base flow existed or when the channel
was pre ominately SW. The SW that,drains from this portion of the CS site enters the channel at
several different locations rather than one defined point. Ms. Stein informed the writer that the channel
was often dry or nearly dry during the warm weather months, which would be indicative of a channel
that originates as an ephemeral channel and begins a transition to intermittent prior to reaching the RR
near the south end of the CS property. Complicating this matter is the fact that CS has both point and
non -point SW sources discharging into this channel, therefore, locating a sampling location that will
capture the SW originating from this portion of the property, but not include superfluous base flow in
the channel will be difficult. Further discussions and/or additional site visits will likely be necessary to
determine whether the current sampling location is the more appropriate location to capture the SW
from the south side of the CS site.
Another likely contributor to this facilities inability to consistently comply with their benchmark limits
is the historical use of the site as a wood preservatives manufacturer. CS has been in operation since
the 60's, and the bioaccumulation of wood preservation constituents are likely prevalent in the soils
and on the equipment scattered throughout the site. Although current SW exposure practices are likely
a significant improvement over those of the past, any constituents that may have accumulated in the
soils and in the industrial process areas have the potential to be released during storm events and
ultimately effect SW quality. CS also has air emissions, but it is unclear as to whether these emissions
could have played a significant role in failure of CS to meet benchmark requirements. There are also
operational improvements that may help in reducing pollutant levels. For example, scrap copper used
in the manufacturing of the wood preservatives is stored in bags at one location on -site, but must be
transported across site by fork-lift to where it is processed. In the area where the bags of scrap copper
are stored for manufacturing, small flakes of copper can be seen on the pavement in the vicinity of the
unloading area that are exposed to rain events. The leaching of copper from these flakes into SW is
highly probably given the acidity of area rainfall. These observations were discussed with Ms. Stein
and operational improvements were suggested.
Zinc has also been problematic at CS with many reported results above benchmark levels, however,
according to Ms. Stein, all sources of Zinc used in the manufacturing process are under roof. Again,
historical manufacturing activities at this facility may be playing a part in the sources of current zinc
levels, but it was noted by the writer that a large part of the site is covered by galvanized metal
buildings and much of the piping used in the manufacturing processes are exposed galvanized piping
which may be slowing leaching zinc into the site's SW during rainfall events and as they corrode. It
was suggested to Ms. Stein that some of the many internal outfalls located throughout the CS property
(including some roof drainage) be sampled to help determine the effect, if any that the metal structures
and piping may be having on zinc concentrations in the site SW. Ms. Stein was amenable to
conducting this sampling in hopes it will -help identify possible sources of zinc. In the meantime, this
Office recommends that the renewed permit incorporate the suggested language (Mandatory Best
Management Practices) that will hold in abeyance tiered testing for benchmark exceedances as long as
the other investigative activities are completed, including the possibility of site specific BMPs based
on the results of a Division approved monitoring plan.

Page Three
In a follow-up to questions asked by the CO regarding this site, Ms. Stein was asked how the
"background" rainfall sample she collected and analyzed was obtained. She said that various
collection containers were placed throughout the site during a rain event. The rainfall in each container
was then combined into one container and the resulting mixture tested for Cu and Zn. Ms. Stein was
also asked if the SW from the loaded trailer parking area went directly to SW or to the WWT lagoon.
Her response was that there was a pipe at the lower end of the trailer parking lot that received all the
SW from this area and was fitted with a valve. Normally, the valve remained open in case of a spill so
the spill would be sent to the WWT lagoon, but during rainfall events, the valve was closed and all SW
was directed to outfall 002.
At this time, CS is not required to conduct any in -stream monitoring for copper or zinc in either their
SW permit or their NPDES wastewater permit. Instream testing may also help CS identify to what
extent they may contributing to the RR's impairment for Cu, especially during storm events. This
testing will be brought to the attention of CS in the inspection report that will be forwarded to the
company.
In conclusion, CS has instituted a number of physical and operational improvements designed to help
reduce contaminant exposure and more are planned in the coming months. With the suggested
language noted above regarding BMP evaluation included in the permit, CS will be able to investigate
and eventually implement management and operational strategies that will hopefully improve SW
pollutant concentrations and possibly effect a reduction in in -stream Cu impairment.
It is recommended that the subject SW permit be issued with consideration given to the
comments/recommendations as contained in this report

Central Office Review Summary:
1. Owner's Other Permits:
• WW - NCO006351
• Air — NE145993, 3702500040
• RCRA -- NCD048467427
2. General Observations:
• 2 SDOs — 001 is a pipe, 002 is a ditch
• Indoor and outdoor storage of materials
• Portions of site drain to onsite W WTP or captured for process'water use
• Site is immediately adjacent to Rocky River
• While some areas drain to the WWTP or process water, stacks could introduce pollutants from these
areas to the air and to stormwater
• They have implemented a number of BMPs to attempt to minimize Cu and Zn exposure (see page 2 of
renewal cover letter dated 9/8/11.
3. Impairment: This segment of Rocky River (13-17b) is impaired for Copper, Turbidity, and Biological Integrity.
The downstream segment (13-17c) is impaired for Copper, Turbidity, and Zinc. No TMDLs for this segment.
4. Threatened and Endangered: None shown in this area.
5. Industrial Changes Since Previous Permit: Volumes of CCA and arsenic acid are decreasing with new organic
products being produced.
6. Anal3jical Monitoring Notes: All samples were above the benchmarks for Cu and Zn. All other parameters were
below benchmarks. Additional monitoring was done on rainfall for Cu & Zn, and groundwater for Zn; Cu in the
rainwater was above the benchmark, and Zn in the groundwater was above benchmark. One thing to note is that
both of these are possible contaminates release from the air stacks onsite. Permittee has requested that the Cu
and Zn benchmarks be raised. However, benchmarks are not changed for individual sites, they are statewide
values used for all facilities. The receiving stream is impaired for Cu, so it is important that the permittee reduce
or eliminate Cu exposure to the maximum extent practicable (MEP). The renewal application does note changes
and BMPs related to Cu and Zn, so they are actively working on minimizing exposure. Due to the permittee's
concerns with the Cu and Zn issues in the sw discharges and the stream impairment, it may also be helpful to do
upstream & downstream monitoring. Another idea would be to investigate installing structural BMPs that are
known to help remove metals from sw (ie. bioretention). They may also need to do some internal investigation to
try and pin point sources. They have a number of BMPs that have already been implemented to target Cu and Zn
(see 2"d page of renewal application letter) W at Ste' (i15� ott ts';antfiis overialliss>ic?
7. Qualitative Monitoring -Notes: Most observations were not of concern. Some results noted foam and low clarity;
one note of high suspended solids noted in 2007/2008.
Revised Permit Recommendations: Analytical Monitoring:
1. Removing lead based on Division's revised monitoring strategy. Recommend removing Arsenic based on all
results being well below the benchmark. All other parameters to remain. COD was not above the benchmark,
but some were elevated; also will be helpful to keep with the shift to organic products.
2. All analytical monitoring remains set to semi-annually during a representative storm event as defined in Part lI
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 remain in 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
Page 3 of 5

NCS000057
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 responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1, 4,
and 5. '
Other Proposed Changes to the Previous Permit:
I . 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 11 Section
A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part 1I 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. 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 § I22.26(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.

Zinc
• Zinc production area is under roof.
• All product storage areas have secondary containment and secondary containment waters go to
waste water treatment.
• Zinc oxide raw material bags are placed in plastic bags prior to disposal in compactor.
• June 2011: due to reduction in site nonhaz waste, compactor has now been removed and
replaced with covered dumpster.
Copper
• 2012: Planned relocation of ACQ-C1 production under roof pending capital expenditure.

• June 2010: began using roll off with metal lid for storage of used ACQ filters.
• June 2010: began rinsing ACQ filters prior to disposal and placement in roll -off boxes to remove
copper content and hence reduce volume and toxicity associated with potential copper
discharges
• March 2010: Repaired (poured new concrete overexisting secondary containment structure)
secondary containment for Copper Count N production area
• March 2010: Coated secondary containment structure for T-251 & T-253
• Main drive improvements were completed in 2006 to completely pave the main drive, curb and
establish catch basins which are routed to the WWT system.
It is also concerning that the benchmark forcopper is lower that actual rainwater results. CSI is
concerned that the current benchmarks are unattainable.

Item # 4. Best Management Practices Utilized at the Facility
Because CSI is a chemical manufacturer, most of the facility Best Management Practices (BMP)
revolve around the concept of minimizing chemical contact with stormwater. In that effort, the
CSI facility uses the following BMPs:
• Indoor storage of product and raw materials where practical.
• Redundant tank level indication.
• Indoor & outdoor tank storage has secondary containment.
• Inorganic secondary containment stormwater goes to WWT system.
• Wood preservative secondary containment stormwater is collected and returned to the
operating process.
• Preventative maintenance to minimize leaks and drippages from the piping systems.
• Tanker, railcar and hose inspection program.
• Full tanker parking area drains to a lined spill lagoon which is part of the WWT system.
• Concrete paved driveways sloped to catch basins which are piped to lined spill lagoon
which is part of WWT system.
• Series of stormwater system drains to minimize erosion
• Series of stormwater gate valves to divert stormwater from river in the event of a spill.
• Curbing and riprap to minimize impact of sheet flow
• Railside track pans
• No on -site maintenance of trucks or vehicles
• Curbing along the south side of driveway to contain potential tanker leaks/spills.
• Nonhaz waste minimization program decreased waste generation from 48 tons to 12
tons/year due to recycling effort and less waste such as raw material product storage
bags was placed in dumpsters.
• Oil water separators to collect oil from air compressors to eliminate possible oil
contamination to stormwater.
• Written operating procedures and operator training.
• Spill kits with drain blankets.
• Semi-annual inspection of secondary containments and stormwater collection drains and
production areas.
• Annual employer stromwater training.
Please find attached a table indicating materials manufactured, handled or stored and the
associated BMP for each specific product. This table is intended to comply Item # 4 on the
Supplemental Information Checklist.
Item # 5. Changes in Industrial Activity
Chemical Specialties Inc is a chemical manufacturer that produces inorganic products for
industrial and agricultural applications and wood preservatives.

Inorganics include metal nitrates such as calcium, magnesium, aluminum, manganese, copper,
lithium and zinc. Metal chlorides including aluminum, magnesium, zinc and manganese are also
produced. Other products produced by the inorganic branch of the business also include metal
acetates, such as magnesium, lithium and zinc. While product mix does vary the product
offering in this product line has remained relatively constant since the last permit issuance.
Wood preservatives manufactured include chromated copper arsenate (CCA), arsenic acid,
alkaline copper quaternary (ACQ), DBlaze fire retardant (phosphor -ammonium boron
compound) and water repellants (wax based products). While these products have been
manufactured or handled at the facility for many years the wood preservative industry is
transitioning from metal based chemistries to organic based chemistries based on
biodegradable biocides called ITAs or chloroisothiazolinones. Hence the volumes of CCA and
arsenic acid are decreasing with launch of the new organic products. The production of these
organic based products includes the storage and handling of new organic chemicals including;
Dowanol, Tergitol, Texanol, castor oil and derivatives, emulsifiers and the organic pesticides
Imidicloprid and Tebuconazole.

Part 11 Page 2 of 10

Permit No. NCS000057
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 (incl ding material storage areas,

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

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

Subject: NCS000057 - Chemical Specialties, Inc. - Stormwater Permit Renewal
lonna,
I wanted to follow up from my voice mail I just left for you. I have a couple questions to ask to help with my review of
your renewal application.
1. How and where was the background rainfall sample collected (open area, from roof drain, etc.); and was it just a
single sample?
2. What method is used to determine if the loaded trailer parking area goes to sw or to ww?
Also, we have noted your concerns in your cover letter and we will work with you on addressing those. One thing to
note is that our benchmarks are based on acute toxicity values that are not adjusted for specific sites. These are the
same benchmarks used for any other sites monitoring for Cu and Zn. That said, we recognize that acute values for these
metals are low, and that their toxicity is highly variable and dependant on water hardness. We may consider site -
specific BMPs in lieu of benchmarks for one or more of these parameters. This is something we have done at a few
other facilities.
Thanks.

SECTION E: MANDATORY BEST MANAGEMENT PRACTICIES (BMPS)
The Permittee shall implement the following BMPs at this facility and shall include these BMPs
in the facility's SPPP:
1. The Permittee shall ensure entryways and loading/unloading areas near manufacturing
areas where copper and zinc exposure could occur are swept and cleaned -up daily, and
that cleaning procedures are conspicuously posted within the affected work areas.
2. The Permittee shall ensure routine evaluations by employee task groups of BMPs
intended to reduce copper and zinc exposure and shall identify practices or areas in need
of improvement.
3. The Permittee shall implement BMPs to reduce copper and zinc exposure, including but
not limited to: storing empty drums and totes indoors; improving preventative
maintenance for any dust collectors; and clean-up from handling and storing of the
powdered and liquid copper and zinc materials. For BMPs that have already been
implemented, the Permittee shall ensure those practices are maintained as long as they
effectively reduce copper and zinc exposure.
4. The Permittee shall devise a Monitoring Plan for sampling runoff from segregated areas
(for example, the roof drains and loading/unloading areas) to determine where the
primary contributions of copper and zinc to stormwater occur at the site. This Monitoring
Plan shall be submitted to DWQ for review and approval within four months of the
effective date of this permit [by May 1, 20121. The Monitoring Plan should require
sampling (grab samples) be conducted during representative storm events. In addition to
other parameters the Permittee deems useful, the Permittee shall analyze copper and zinc
concentration and estimate flow volume for each sampled event. If averages will be used,
the plan should include criteria about how many samples are required. If the Perrnittee
will evaluate the proportion of contribution to the total mass of copper and zinc in runoff
from the entire site, measurements should be taken concurrently at stormwater discharge
outfalls. Revisions to the Monitoring Plan shall not require a revision to the Stormwater
Permit. Any revision of the Monitoring Plan after the initial review and approval of
DWQ shall be accomplished by mutual agreement between DWQ and the Permittee.
For areas the Permittee has determined to be primary contributions to copper and/or zinc
in runoff from this facility, either through the above Monitoring Plan or by other means,
the Permittee shall assess BMPs intended to reduce copper and zinc release and exposure
from industrial activities, reduce other sources of copper and zinc contamination, and/or
capture and treat the runoff with engineered controls. The Permittee shall establish a
schedule to implement selected BMPs and shall submit a status report to DWQ outlining
progress two and a half years following the effective date of this permit [by June 30,
20131. The BMPs assessment and recommendations may focus on copper and zinc
sources attributable to industrial activities and materials, but the report should list any
other influences that are suspected to, or were determined to, contribute significant
amounts of copper and zinc to the stormwater discharge.

Marcia have been out of the office for a couple of days. Returning your call. The storm drain does eventually makes its
way to the Rocky River but it would be a torturous path (intersecting with other storm drains, swans etc) and is probably a
mile away from the River.
Hope this answers your question.

Subject: Notification of Sewage Leak to Stormwater: Chemical Specialties Inc., NCS
000057.
_.__._........_._ ._ _ .... Dear Mrs. Alloco:
The purpose of this letter is to follow up on our phone conversation on March 12, 2010 at
approximately 4:30 pm and to provide written notification to the Division as per our
operating permit section Part III E.8 or "Twenty-four Hour Reporting."
At approximately 4:00 pm on Friday March 12, 2010, CSI became aware of sewage
flowing to a storm drain. A drain blanket was placed over the storm drain at
approximately 4:15 pm. It is estimated that approximately 100-200 gallons of material
back flowed from the line to our septic drain Meld out onto the ground and then into the
storm drain.
The area was investigated by our maintenance staff and the most likely cause was thought
to be an underground leak of the line running to the septic drain field from the office
trailers. I observed that the flow had ceased at 5:00 pm on Friday evening. Contractors
arrived on site Monday morning and repaired a piece of underground ruptured 2" PVC to
the septic drain field. The issue was corrected by 11:00 am on 3/15/2010.
Thank you for your consideration of this issue. If you need additional information please
do not hesitate to contact me at 704-455-4171 or jonnas _,chemspec.corn.

Dear Ms. Stein:
Enclosed with this letter is a' copy of the draft stormwater permit sent on September 14,
2005 that was developed by the Division's central and regional staff. The significant changes to
your previous permit are summarized in the cover letter of this permit. As we discussed on the
telephone, this letter was addressed -to your predecessor who has since retired. For that reason, I
am re -sending the draft permit for your review and comment. I have revised the draft sent in
2005 to reflect that the permit will be signed and effective in 2007, and that it will expire in
2012. This new draft permit is also enclosed. Other than this change, the draft permit from 2005
has remained unchanged: Please provide'any comments to me no later than thirty (30)' days ._ '
following the receipt of this letter. Comments should be sent to the address listed at the bottom
of this page. Concurrently, the Division will publish a public notice in your local paper in order
to advise the community of this change and to solicit their feedback. The public will be given
until February 8, 2007 to submit comments to the Division. If no adverse comments are received
from the public or from you, this permit will likely be issued in about two months.
If you have any questions or comments concerning this draft permit, please contact me at
919.733.5083 x376 or [e-mail].

PART II MONITORING, CONTROLS, AND LIMITATIONS FOR 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:
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 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.
(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.
(c) A site map drawn to scale with the distance legend indicating location of industrial activities
(including storage of materials, disposal areas, process areas and loading 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 B, Paragraph 3.
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 Schedule. A schedule to provide secondary containment for bulk storage
of liquid materials, storage of Section 313 of Title III of the Superfund Amendments and
Reauthorization Act (SARA) water priority chemicals, or storage of hazardous substances to
prevent leaks and spills from contaminating stormwater runoff_ .If the secondary contairtmP! t",-
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 with a
locking mechanism] and any stormwater that accumulates in the containment area shall be at a
Part II Page I of 5

Permit No. NCS000057
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 release shall be kept for a period of five years.
(c) BMP Summary. A narrative description shall be provided of Best Management Practices (BMPs)
to be considered such as, but not limited to, 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 potential of 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, 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 and systems. Inspection of material handling areas and regular cleaning
schedules of these areas shall be incorporated into the program.
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 which 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 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 permittee shall provide certification in
writing (in accordance with Part III, Standard Conditions, Section B, Paragraph 3) to the Director that the
changes have been trade. a •. ; ..•s..:.� -_ =Y.., .�>' . _
8. Facility Inspection Program. 'Facilities are required to inspect all stormwater systems on at least a
semiannual schedule, once in the fall (September -November) and once in the spring (April - June). 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 ary _, .1ems-Records of these in p bons shall be
incorporated into the Stormwater Pollution Prevention Plan. .
