Section 1. Facility Activities and Process:
Venator Chemicals, LLC is a chemical manufacturer that produces pesticides and inorganics for wood
preserving, agricultural, and industrial companies. Products produced include alkaline copper quaternary
(ACQ), copper chromated arsenate (CCA), arsenic acid, and other copper-based pesticides; binary salts
of aluminum, calcium, magnesium, manganese, copper, zinc, lithium, and sodium; and nitrates, nitrites,
chlorides, and acetates.
Per the permit file history, the facility has also produced metal nitrates (calcium, magnesium, aluminum,
manganese, copper, lithium, and zinc), metal chlorides (aluminum, magnesium, zinc, and manganese),
metal acetates (magnesium, lithium, and zinc), organic biodegradables (organic biocide, D-Blaze fire
retardant [diammonium phosphate], and wax-based water repellants), and organic chemicals (castor oil
and derivatives, emulsifiers, and organic pesticides Imidicloprid and Tebuconazole).
Per the permit renewal application, the previous owner, Chemical Specialties, Inc. (CSI), requested an
increase of the benchmark values for copper and zinc to 150 µg/L and 300 µg/L, respectively. CSI stated
the implementation of various BMPs period did not correlate to any decreases in the discharge values for
copper or zinc (CSI states zinc is due to the large quantity of galvanized roofing and chain link fence,
and tire dust from fork trucks and tanker trailers). CSI additionally states previous water samples
collected by CSI from the Rocky River indicate higher values for copper and zinc upstream of their
facility than downstream.
Per the permit renewal application, the previous owner CSI stated the following site operations have
changed since the last permit renewal:
• Approximately 80% of copper is received in "chopped" form and transported in super sacks.
Page 1 of 9

• Wood preservative industry has transitioned from metal-based to organic based chemistries
based on biodegradable biocides called ITAs or chloroisothiazolinones. The volumes of CCA
and arsenic acid are minimal with launch of the new organic products.
o Production of organic based products includes storage and handling of new organic
chemicals (castor oil and derivatives, emulsifiers, and organic pesticides Imidicloprid and
Tebuconazole).
• Discontinued handling organic based products Dowanol, Tergitol, and Texanol.
Per information submitted by the permittee on 1/5/2023, the textile plant which produced Magnesium
Chloride solution has been idled. The storage tanks are empty and the secondary containment pit has
been cleaned out via pressure washing. Stormwater from this area is analyzed, inspected, and
discharged. Containerized products (totes, drums, bags of finished products and raw materials) are
stored in warehouses. When stormwater is collected, it is either pumped to the permitted wastewater
treatment system or collected in tanks for reuse back in process. A few containments are pumped to
stormwater after a visual inspection and/or analytical testing. Nonhazardous waste and recycle collection
containers are exposed to stormwater. There are a small amount of totes which are stored outside. The
site also has a tanker parking area which is exposed to stormwater. Site has stormwater gate valves
where applicable.
Per an inspection performed by the regional office in November 2022, no concerns were noted at the
time with the facility or the outfalls. Per previous inspection reports, the facility had been in operation
since the 1960s and the bioaccumulation of wood preservation constituents are likely prevalent in the
soils and on equipment scattered throughout the site. Small flakes of copper were seen on the pavement
in the vicinity of the unloading area that are exposed to rain events. Historical manufacturing activities
at this facility may have played a part in the sources of zinc levels, but a large part of the site was
covered by galvanized metal buildings and galvanized metal piping was found throughout the site. Items
produced by the facility included calcium nitrate, zinc nitrate, copper nitrate and sodium nitrate.
Outfall SW001:
Drainage area consists of truck scales, facility buildings, above ground storage tanks, lined lagoon,
loading docks/areas, and parking lots.
Outfall SW002:
Drainage area consists of truck scales, firewater tank, facility buildings, and above ground storage tanks.
Why Industrial Sites with Stormwater are Subject to a Permit: Federal NPDES regulations define
stormwater discharge associated with industrial activity in 40 CFR §122.26 (b)(14) as: "the discharge
from any conveyance that is used for collecting and conveying storm water and that is directly related to
manufacturing,processing or raw materials storage areas at an industrial plant. The term does not
include discharges from facilities or activities excluded from the NPDES program under this part 122.
For the categories of industries identified in this section, the term includes, but is not limited to, storm
water [sic] discharges from industrial plant yards; immediate access roads and rail lines used or traveled
by carriers of raw materials, manufactured products, waste material, or byproducts used or created by
the facility; material handling sites; refuse sites; sites used for the application or disposal of process
waste waters (as defined at part 401 of this chapter); sites used for the storage and maintenance of
material handling equipment; sites used for residual treatment, storage, or disposal; shipping and
receiving areas; manufacturing buildings; storage areas (including tank farms) for raw materials, and
intermediate and final products; and areas where industrial activity has taken place in the past and
Page 2 of 9

significant materials remain and are exposed to storm water. For the purposes of this paragraph, material
handling activities include storage, loading and unloading, transportation, or conveyance of any raw
material, intermediate product, final product, byproduct or waste product. The term excludes areas
located on plant lands separate from the plant's industrial activities, such as office buildings and
accompanying parking lots as long as the drainage from the excluded areas is not mixed with storm
water [sic] drained from the above described areas."

Section 3. Proposed Monitoring for Stormwater Discharges:
The Division considered potential pollutants from past and present industrial activities and data was
submitted for May 2012 to December 2022. Quantitative sampling included pH, TSS, COD, fecal
coliform, copper, manganese, zinc, O&G, total nitrogen, TKN,Nitrate+Nitrite, and total phosphorus.
Parameters are based on potential pollutants in the drainage area, sampling results, and in some cases,
dependent upon future activities (e.g., ash removal through the drainage area). Below is a table of the
proposed monitoring for each outfall at the Venator Chemicals, LLC site.

Stormwater Benchmarks and Tiered Response: Rather than limits,North Carolina NPDES
Stormwater permits contain benchmark concentrations. Stormwater benchmarks are numerical action
levels for stormwater monitoring. Benchmarks are not effluent limits, and benchmark exceedances are
not permit violations. Benchmarks provide facilities a tool for assessing the significance of pollutants in
stormwater discharges and the effectiveness of best management practices (BMPs). Benchmark
concentrations are intended as guidelines for the facility's development and implementation of the
Stormwater Pollution Prevention Plan (SWPPP).
Page 5 of 9

Benchmark exceedances require the permittee to increase monitoring, increase management actions,
increase record keeping, and/or install stormwater BMPs in a tiered program. The permit establishes a
tiered approach to specify actions the permittee must take in response to analytical results above
benchmark concentrations. The tiered structure of the permit provides the permittee and DEMLR wide
flexibility to address issues that may arise with one or more parameters and/or outfalls.
Metals benchmarks are calculated to mimic acute water quality standards and with the guidance of
DWR. NC DWR follows established federal procedures for calculating acute standards when developing
the benchmarks. Just like the acute standards, metals benchmarks normally reflect one half of the
calculated Final Acute Value (the "1/2 FAV"). In most cases, translation into total recoverable values is
based on an assumed hardness of 25 mg/L and a total suspended solids (TSS) concentration of 10 mg/L.
Acute standards protect aquatic life from negative impacts of short-term exposure to higher levels of
chemicals where the discharge enters a waterbody. The Stormwater Permitting Program applies this
approach because of the ephemeral nature of rainfall events.
The Division may evaluate results to determine if a smaller suite of parameters for some outfalls is
adequate to characterize potential pollution or BMP effectiveness. For example, one or more metals or
other parameters may serve as an adequate tracer for the presence of ash pollution during disturbance or
ash removal in specific drainage areas at this site. For parameters that do not have a stormwater
benchmark, the Division may develop a benchmark value if appropriate toxicity data become available
or if rising trends in concentrations suggest a persistent source.
A summary of the benchmarks in the draft permit, and their basis, is below:
Parameter Benchmark Basis
Total Suspended 100 mg/L National Urban Runoff Program(NURP) Study, 1983
Solids TSS
H 6 s.u. —9 s.u. NC Water Quality Standard(Range)

Page 6 of 9

Stormwater Pollution Prevention Plan: The proposed permit conditions reflect the EPA and NC's
pollution prevention approach to stormwater permitting. The Division's maintains that implementation
of Best Management Practices (BMPs) and traditional stormwater management practices that control the
source of pollutants meets the definition of Best Available Technology (BAT) and Best Conventional
Pollutant Control Technology(BCT). The permit conditions are not numeric effluent limitations but are
designed to be flexible requirements for implementing site-specific plans to minimize and control
pollutants in stormwater discharges associated with the industrial activity. Title 40 Code of Federal
Regulations (CFR) §122.44(k)(2) authorizes the use of BMPs in lieu of numeric effluent limitations in
NPDES permits when the agency finds numeric effluent limitations to be infeasible. The agency may
also impose BMP requirements which are "reasonably necessary" to carry out the purposes of the Act
under the authority of 40 CFR 122.44(k)(3). The conditions proposed in this draft permit are included
under the authority of both of these regulatory provisions. In essence, the pollution prevention and BMP
requirements operate as limitations on effluent discharges that reflect the application of BAT/BCT.
Flexibility in Tier Responses: Tier Two actions provide an opportunity for the permittee to propose an
alternative monitoring plan for approval by the Region:
• Alternatively, in lieu of steps 2 and 3, the permittee may, after two consecutive exceedances,
exercise the option of contacting the DEMLR Regional Engineer as provided below in Tier
Three. The Regional Engineer may direct the response actions on the part of the permittee as
provided in Tier Three, including reduced or additional sampling parameters or frequency.
• If pursuing the alternative above after two consecutive exceedances, the permittee may propose
an alternative monitoring plan for approval by the Regional Engineer.
The permit therefore allows the permittee to petition the Regional Office for monitoring changes sooner
than Tier Three (upon any four benchmark exceedances) and gives guidance on one option to take. For
example, the permittee may request that mercury only be monitored semi-annually under the tiers, or
that only parameters over the benchmark be monitored more frequently. In this way, changes to the
monitoring scheme for any outfall could be handled outside of a permit modification.
Other Proposed Requirements:
• It is standard for Stormwater Pollution Prevention Plan(SWPPP)requirements to include an
annual certification that stormwater outfalls have been evaluated for the presence of non-
stormwater discharges, and if any are identified, how those discharges are permitted or otherwise
authorized.
• Requirement to submit a request for permit modification if the facility identifies or creates any
new outfalls, removes outfalls, or alters any drainage area that changes potential pollutants.
• The Division expects the permittee to apply best professional judgment and consider the safety
of its personnel in fulfilling sampling obligations under the permit.
• Federal regulations require electronic submittal of all discharge monitoring reports (DMRs). If a
state does not establish a system to receive such submittals, then permittees must submit DMRs
electronically to the EPA.
• Quarterly QualitativeNisual Monitoring to assure regular observation of outfalls throughout
year.

Section 4. Changes from previous permit to draft:
• Regulatory citations have been added
• Monitoring increased from semi-annually to quarterly for all parameters (qualitative and
quantitative)
• "No discharge" clarifications made
• eDMR requirement added
• Feasibility study and online SWPPP certification requirements have been removed per updated
Stormwater Program requirements
• Outfall specific monitoring implemented

• Benchmarks updated for parameters per guidance from DWR Standards group on stormwater
benchmarks
• Monitoring for total hardness added for all outfalls as monitoring for hardness dependent metals
is required
• Total recoverable copper and total recoverable zinc updated to Total Copper and Total Zinc
o Now subject to Tiered Response with benchmark exceedances
• Owner name updated on cover sheet

nitrate+nitrite), arsenic, and magnesium as information submitted with permit renewal
application indicate these pollutants are onsite therefore there is a potential to be discharged
o Monitoring for arsenic added as products produced contain arsenic; removed from
previous permit as values below benchmark
• Monitoring for total hardness added as monitoring for hardness dependent metals are required
• BMP condition(Part K)has been updated
Section 5. Changes from draft to final:
• Part B-7 missing text added per draft permit comments
• Part I-1 reference corrected per draft permit comments
• Part B-13 missing text added per draft permit comments

Summary Data Monitoring Report to the appropriate DWQ Regional Office by March 1
of each year. The submittal shall be on forms supplied by the Division." In the draft
permit I did not find any requirement for annual reporting but wanted to check before
discontinuing the practice. Please kindly confirm.
■ DEMLR response: The annual report is still required, however, it does not need
to be submitted to the Division. Please see the updated Part B-13.e. of the permit.
o We discussed applying for relief from benchmarks, can you send me to the appropriate

I guess we need to modify slightly, due to removing the monitoring plan section. Number 4 probably needs to be
modified as you see below.
PART E. MANDATORY BEST MANAGEMENT PRACTICES (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
exposure could occur are cleaned-up after use, and that cleaning procedures are conspicuously posted within the
affected work areas. Any spills of material shall be cleaned-up by the end of the work shift, or before if rainfall is
expected prior to the end of the work shift.
2. The Permittee shall perform routine evaluations 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/totes/bales under cover and requiring clean-up resulting 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. For areas the Permittee has determined to be primary contributions to copper and/or zinc in runoff from this
facility,the Permittee shall continue to 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.
5. Within 1 year from the effective date of this permit,provide NCDEQ DEMLR a report documenting the history
of benchmark exceedances for this location,the current status of BMP exceedances, a listing of the BMPs
implemented to address the exceedances, and a discussion of potential BMPs that have been evaluated but not
implemented.

Brianna:
We agree with your assessment that most of the provisions of Section E are still needed for this facility.
Our recommendation is:
• Leave#1 unchanged.
• Change#2 to say, "The Permittee shall perform routine evaluations of BMPs intended to reduce copper and zinc
exposure and shall identify practices or areas in need of improvement."
• Leave#3 unchanged.
• Delete#4.
• Change the number for#5 to "#4" and then delete the line about "establishing a schedule", as you proposed.
• Add a new#5 as follows: "Within 1 year from the effective date of this permit, provide NCDEQ DEMLR a report
documenting the history of benchmark exceedances for this location,the current status of BMP exceedances, a
listing of the BMPs implemented to address the exceedances, and a discussion of potential BMPs that have been
evaluated but not implemented."
Brianna: The new#5 described above is needed because although the facility has done some additional monitoring and
identified some potential sources,they are still having results above the benchmarks. This new#5 will challenge them
to tabulate their data, document what's been done, and think about other things they could be doing...
Please let me know if you have questions or comments.

Good afternoon,
I am working on the renewal application for the Venator Chemicals stormwater permit NCS000057.The previous permit
had a BMP section requiring them to do some investigation and BMP implementation (see below). Do you all feel they
need to maintain this condition, or parts of this condition? Based on their monitoring data, I recommend we keep#1,#2,
#3, and most of#5 (excluding the line "The Permittee shall establish a schedule...". Do you have any thoughts on this?

4. The Permittee shall devise a Monitoring Plan for sampling runoff From segregated
areas [fnr exarnple, the roof drains and loading unloading areas) to determine
where the primary contributions of capper and zinc to stormwa ter occur at the site.
The permittee may also include performing upstream and downs trea m monitoring
during rain events of the receiving stream to help identify to what extent the facility
may he contributing to the stream's impairment For copper. This Monitoring Plan
shall be submitted to DWQ for review and approval within four months of the

require sampling (grab samples) be conducted during measurable storm events. In
addition to other parameters the Permittee deems useful, the Permittee shall
analyze copper and zinc concentration and estimate flaw volume for each sampled
event If averages will be used, the plan should include criteria about hove+ many
samples are required, If the Permittee 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 flan after the initial review and approval of DWQ shall be

Good afternoon Jonna,
I am reviewing the information you provided a few weeks ago and had one follow-up question. Could you please clearly
identify what industrial activities take place in each drainage area?What I could determine based on the maps provided
is below:
Outfall SWO01: Drainage area consists of truck scales,facility buildings, above ground storage tanks, lined lagoon,
loading docks/areas, and parking lots.
Outfall SWO02: Drainage area consists of truck scales,firewater tank, facility buildings, and above ground storage tanks.

Best Management Practices Utilized at the Facility
Because Venator is a chemical manufacturer, most of the facility"Best Management Practices(BMPs) revolve around
the concept of minimizing chemical contact with stormwater. In that effort,Venator uses the following BMPs.
• Indoor warehouse storage of containerized raw materials and finished goods.
• Tank storage with secondary containment structures and redundant level indication
• Railside track pans that drain to WWT or secondary containment structures.
• Some tank farms have roof structures to minimize stormwater generation.
• Site drainage system that routes stormwater away from process areas where practical.
• Stormwater drainage system which allows management of stormwater to the stormwater outfalls,the
emergency spill lagoon (Lagoon#1) or to the facility waste treatment system and minimizes erosion.
• For the inorganic production area (nitrates, nitrites, and acetates)storm waters are routed to the Site's
permitted wastewater treatment system which is managed via the Site's NPDES discharge permit NC0006351.
• Pesticide manufacturing tank storage areas have dedicated secondary containments and stormwaters are
collected and stored in tanks for reuse back in the production process.
• Preventative maintenance programs to ensure equipment is in good order and minimize chemical exposure to
stormwater via equipment or piping malfunctions.
• Tanker truck, railcar, and hose inspection programs.
• Tanker parking area is slopped to a concrete drainage swale that is routed to emergency spill lagoon (lined
lagoon)
• Curbing and rip rap to minimize sheet flow.
• Stormwater gate valves on certain drains which can be closed in the event of a spill or release.
• Use of covered roll offs for storage of nonhaz or recycle materials where practical.
• Oil water separators to collect oil from air compressor systems to eliminate oil contamination to stormwater
• Operator attendance for loading and unloading activities.
• Operating procedures and operator training.
• Spill kits at loading/unloading areas and mobile spill kit for larger events.
• Semi-annual inspection of catch basins,secondary containment structures
• Monthly SPCCC inspection of oil storage areas and spill kits.
• Annual stormwater and SPCC training.
• Copper handling and management program.
• Site does not meet the requirement for on site vehicle maintenance>55 gal/day average of motor oil per
month.
Supplemental Information Item No.5
Significant Changes In Industrial Activity
• The textile plant which produced Magnesium Chloride solution has been idled.The storage tanks are empty and
the secondary containment pit has been cleaned out via pressure washing.Stormwater from this area is being
analyzed and inspected and discharged.

Best Management Practices Utilized at the Facility
Because Venator is a chemical manufacturer, most of the facility "Best Management Practices(BMPs) revolve around
the concept of minimizing chemical contact with stormwater. In that effort,Venator uses the following BMPs.
• Indoor warehouse storage of containerized raw materials and finished goods.
• Tank storage with secondary containment structures and redundant level indication
• Railside track pans that drain to WWT or secondary containment structures.
• Some tank farms have roof structures to minimize stormwater generation.
• Site drainage system that routes stormwater away from process areas where practical.
• Stormwater drainage system which allows management of stormwater to the stormwater outfalls,the
emergency spill lagoon (Lagoon#1) or to the facility waste treatment system and minimizes erosion.
• For the inorganic production area (nitrates, nitrites, and acetates)storm waters are routed to the Site's
permitted wastewater treatment system which is managed via the Site's NPDES discharge permit NC0006351.
• Pesticide manufacturing tank storage areas have dedicated secondary containments and stormwaters are
collected and stored in tanks for reuse back in the production process.
• Preventative maintenance programs to ensure equipment is in good order and minimize chemical exposure to
Stormwater via equipment or piping malfunctions.
• Tanker truck, railcar, and hose inspection programs.
• Tanker parking area is slopped to a concrete drainage swale that is routed to emergency spill lagoon (lined
lagoon)
• Curbing and rip rap to minimize sheet flow.
■ Stormwater gate valves on certain drains which can be closed in the event of a spill or release.
• Use of covered roll offs for storage of nonhaz or recycle materials where practical.
• Oil water separators to collect oil from air compressor systems to eliminate oil contamination to stormwater
• Operator attendance for loading and unloading activities.
• Operating procedures and operator training.
• Spill kits at loading/unloading areas and mobile spill kit for larger events.
• Semi-annual inspection of catch basins, secondary containment structures
• Monthly SPCCC inspection of oil storage areas and spill kits.
• Annual stormwater and SPCC training.
• Copper handling and management program.
• Site does not meet the requirement for on site vehicle maintenance>55 gal/day average of motor oil per
month.
Supplemental Information Item No. 5
Significant Changes In Industrial Activity
• The textile plant which produced Magnesium Chloride solution has been idled.The storage tanks are empty and
the secondary containment pit has been cleaned out via pressure washing. Stormwater from this area is being
analyzed and inspected and discharged.

Subject: NPDES Stormwater Permit Coverage Renewal
Chemical Specialties, Inc
Permit Number: NCS000057
Dear- Mr. Bennett:
C:-mical Specialties, Inc. (CSI) is submitting the attached supplemental information for renewal of an
incividual National Pollutant Discharge Elimination System (NPDES) stormwater permit. Included in this
r,zckage are two copies of the following:
Site maps: SP-000-01, Drain 2008, Drain 2008-2
Summary of Analytical Monitoring results
Summary of Visual Monitoring results
Summary of Best Managment Practices
Signifiant changes in industrial activities
Certification of the development and implementation of a Stormwater Pollution Prevention Plan
X—rg with this permit renewal package, CSl respectfully requests a reevaluation of the current
i-e>)chmark values for copper and zinc. An extensive effort has been made to reduce the discharge
%",kjes of these two parameters. CSI has implemented both physical Best Management Practices (BMPs)
and procedural BMPs, however, sample results remain variable for both. Due to the large quantity of
galvanized roofing and chain link fence, as well as tire dust from fork trucks and tanker trailers, zinc is
uhinuitously present throughout our facility. Based on historical empirical data, the implementation of
various BMPs during the previous nine year period did not correlate to any decreases in the discharge
values for copper or zinc. CSI's Stormwater discharges are into the Rocky River in the Yadkin-Pee Dee
river basin via Outfall #1 and Outfall #2.

Currently,there are not any established TDMLs for copper and zinc in this part of the Yadkin-PeeDee
river basin. The Rocky River(stream index 13-17)is designated a Class C waterway. Previous water
samples collected by CSI from the Rocky River indicate higher values for copper and zinc upstream of
our facility than downstream. In efforts to achieve continuous compliance with our stormwater
discharge permit and to prevent any quantitative water quality exceedances, CSI would like to request
an increase of the copper benchmark value to 150 micrograms per liter and 300 micrograms per liter for
zinc.
If you have any questions or need additional information, please contact me at [phone].
Sincerely,
Jeffrey Bruening
EHS Manager

Supplemental Information Item No. 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 employee stromwater training.
• Copper handling and management program.
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.

Supplemental Information Item No. 5
Changes in Industrial Activity
In order to minimize stormwater exposure to copper, CSI is now receiving approximately 80
percent of our copper in "chopped" form and transported in super sacks. CSI believes the
implementation of this Best Management Practice (BMP)will significantly reduce stormwater
copper exposure. CSI continues to be 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.
Organic biodegradables manufactured include organic biocide, alkaline copper quaternary
(ACQ), chromated copper arsenate (CCA), 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 has
transitioned 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
minimal with the launch of the new organic products. The production of these organic based
products includes the storage and handling of new organic chemicals including; castor oil and
derivatives, emulsifiers and the organic pesticides Imidicloprid and Tebuconazole.
CSI has discontinued handling the following organic based products since issuance of the
previous Stormwater permit: Dowanol, Tergitol andTexanol.
