Supplemental Information , Item 4) BMP summary for
Stockhausen, Inc.
Greensboro, North Carolina
Stockhausen, Inc. is authorized to discharge stormwater associated with industrial activity under an
individual National Pollutant Discharge Elimination System (NPDES) permit (Permit No.
NCS000010). According to Part 11, Section A of the individual permit, Stockhausen is required to
develop and implement a Stormwater Pollution Prevention (SWPP) Plan. Stockhausen has already
developed and implemented an Emergency Response Plan that encompasses stormwater discharge,
wastewater discharge, fire, air discharges, material spills, and waste disposal practices. Stockhausen
has also developed a Stormwater Best Management Practices Plan, which discusses each area of the
facility in relation to potential stormwater pollution and the best management practices implemented
to prevent stormwater pollution.
The following outline lists the SWPP Plan requirements in the individual permit and provides a cross-
reference to sections of the Emergency Response Plan and Stormwater Best Management Practices
Plan, which satisfy the SWPP Plan requirements. The BMP procedures are incorporated in the site
ISO14001 procedures and audited semi-annually.

BEST MANAGEMENT PRACTICES STORMWATER OVERVIEW
Fuel Oil Storage
All fuel oil tanks will be stored in a solid concrete containment. All fuel oil in tanks over 1000 gallons
are stored in reinforced concrete dikes designed to hold the capacity of the largest size tank in the
containment plus 11 10% free board and enough freeboard to contain a 20 year storm (roughly 6
inches).
Chemical Storage Tanks
All chemical tanks are installed in reinforced concrete dikes that are sized to handle the largest tank in
storage plus a six inch free board. Where materials stored are corrosive to concrete there is a chemical
resistant epoxy coating in placed and maintained to prevent corrosion to the containment structure. In
February 2000, all storage tank containment structures were re-evaluated for containment integrity and
capacity. Several of the older tank farms were notched to allow over flow into adjacent compatible
tank farms to increase the free board capacity to match the updated 20 year storm rating.
UNLOADING ACTIVITIES:
Oils:
All unloading of bulk tankers into storage tanks over 1000 gallons takes place on a concrete pad with
spill containment in the stormwater drainage area.
I. Plant 1, 2, 5 and 3 production main yard has four unloading areas. There are curbs or trenches
around all natural animal fat oil/fatty acid wax hot boxes to contain any spills in drum handling in
the central main operation area.. All stormwater culverts in this area drain to a 5000 gallon basin
with a 24 inch slide gate cutoff valve. This valve is closed at all times except during a significant
rain event when it is necessary to open the valve to prevent plant flooding.
2. Plant 4 has a 14" trench below the unloading area that drains into the 16,000 gallon area storage
dike. This is functional at all times including during a significant rain event.
3. The main yard,(Plants 1,2,3,&5), and Plant 4 production areas (approximately 13 acres) drain to a
Stormwater pond constructed in the fall of 2002. This pond is both a hold-up and spill
containment facility. The discharge valve is closed and only released during rain events after
testing.
4. Plant 6 has a series of stormwater and spill containment trenches outside the hazardous material
storage area and the tanker unloading shed. These are designed to separate clean rain flow from
potentially contaminated unloading areas. The stormwater trenches release into a 48 inch culvert
with a cut-off slide gate valve that is visually monitored daily.
Acids/Bases:
1. The Acrylic acid and Sodium Hydroxide unloading occurs in three locations. There are covered
truck tanker unloading areas associated with Plant 3 and Plant 6. These areas are curbed,
contained, coated with appropriate epoxy protection and covered to minimize rainwater
contamination. Both of these areas have 1000 gallon spill containment sumps.
2. Railcar unloading spur is designed to store six acrylic acid and three caustic railcars under rain
cover and over full epoxy coated containment.

SITE OUTFALLS—
Treatment, operational procedures to control runoff, spillage, leaks , sludge or waste or raw
material drainage.
The main site production area encompassing Plant 1,2, 3, and 5 all drain to a 2800 gallon containment
sump with a 24 inch slide gate cut off valve. This valve is maintained shut at all times and is only
opened during a rain event after being visually inspected by the acting Plant 1 supervision. This
containment sump has a sump with a sump pump routed to process waste water so that spills that need
to be washed up can be transferred to waste water treatment if they meet the discharge permit or
sucked up for proper disposal. The stormwater release from this 2800 gallon sump now goes to the
new stormwater containment pond.
There are cutoff valves at all of the processing areas outfalls. This enables operations to keep any
uncontrolled event on the site. Removal of public street flow from the site and new improved
impoundment structures throughout the site was completed in 2002 . At this time a 25 year
containment pond for the processing areas including Plant 1,2,3,4 &5 was completed with new
inspection and release procedures implemented.
SITE GOOD MANUFACTURING PRACTICES
1) There will be no open pipe ends or open vessels. All pipe -ends will be capped or blind -flanged.
All tank drains will be capped or blind -flanged at all times.
2) Containers will not be stored outside a building or covered area unless the container is weather
resistant, the container is labelled and properly lidded tight shut. Containers will not be stored
anywhere outside a building or covered area that does not have secondary containment.
3) Transfer hose will be colored coded for specified use and stored at all times not actively in use in a
contained hose storage rack system.
4) All areas will be maintained free of debris. (e.g. no free food containers, used gloves or other
personel protection equipment ).
5) Spill must be cleaned up on the shift and by the shift it occurs.
GOOD HOUSEKEEPING POLICY
Good housekeeping policies can minimize and in many cases eliminate loss of pollutants to
storm water. The development of housekeeping policies and employee training on the
continued importance of housekeeping is a major focus of the overall BMP plan. The
following elements are the framework of the ongoing housekeeping policies at Stockhausen:
➢ neat and orderly storage of production materials,
➢ chemicals containers cannot be stored outside building unless the container is weather resistant or
the chemical is stored in an area with ample secondary containment,
➢ clean-up of any spilled material must be started on the shift during which it occur,
➢ floors are maintained clean and dry in work areas,
➢ drum and other material container management,
➢ process areas must be kept free of debris and solid waste must be disposed of properly,
➢ assignment of designated storage areas; and,
➢ prompt removal of collected storm water from containment areas and ditches.
Management Procedures. Area Supervisors are responsible for updating annually and maintaining all
plant procedures that enforce the above Best Management Practices in the plant ISO14001 procedures.

Item 5.) Narrative description of Significant changes in Industrial Processes
With industrial activity expansions in the past five years, there have been major modifications to the
site. Since 1999, this site has grown from 19 acres to 26 acres involved in industrial activities. There
are now a total of 56.5 acres in fenced area of a total of 57.5 acres. The internal streets have been
closed off to public access and a major stormwater control project was implemented with over 1.2
million dollars investment over three years.
One of the effects of these improvements is that the stormwater outfall SDO1 now does not have any
industrial related activity related to it. It is mainly the public thoroughfare Elm -Eugene runoff and an
office building with unrelated business administrative activities occuring. There are currently
negotiations to lease/sell this property. Due to this, Stockhausen, Inc would like to request that this
outfall be removed from the site permit at this time leaving three outfalls , SD02, SD03 and SD04.
Below is a summary of the physical and operational changes implemented since 1999
Physical BMP Improvements since 1999
i.) Re-routed all areas inside the parameter of Patton street to the north side of Higgins all the
way to the East site border at the NS railroad to collect in a 25 year stormwater holdup and
containment pond with slide -gate control at outfall.
ii.) Provide containment of spills from main process areas by adding curbing and trenches in
operational specific areas. In 2002, installed a series of containment improvements in Plant 1,
2, and 5 main yard as summarized below:
➢ Cooling tower containment improvements,
➢ re-routing of steam condensate exhausts,
➢ hydraulic motor containment improved with sheds and curbing,
➢ added trenching to remove sheet flow from unloading areas in Plant 1
➢ Sealed all trenches in unloading to prevent chemical spills to secondary containment
sumps. Allowed area cleanup to occur after unloading operations.
➢ Upgraded curbing throughout the operational area to segregate activities.
iii.) Remove excess water volume from Patton Street across the main process stormwater
collection area under the NF railroad to a new 24 inch invert and discharge to No -name
Creek.
iv.) Corrected the current silting and wash over of process area from up -hill non -process areas by
adding a 150 foot concrete swale with 24 inch cutoff valve uphill of Plant 5. This area now
discharged flow to new pond.
V.) Provide containment of spills in stormwater system from P6 , W 14 and Railcar facility on north
side of property by adding a 48 inch cutoff valve with a cleanout screen.
vi.) W 14 area public street culvert diversion by adding a 24 inch culvert and separate outfall for
the Elm -Eugene street stormwater flow parallel to the existing 48 inch culvert for the site.
Operational Changes since 1999
i.) Expanded Plant 6 by doubling the size and capacity of the superabsorbent chemical -
manufacturing site.
ii.) Demolished a warehouse and constructed a acid/caustic rail unloading facility on the North
side of the property adjacent to Warehouse 14 on N Terrell Street. It has four rail spurs and
can unload three acid and one caustic rail car simultaneously in a complete sheltered and
concrete diked containment area.

Permit No. NCS000010
Evonik Stockhausen, Inc.
Guilford County
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please review the draft
very carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from this facility's current permit:
Analytical monitoring changes:
1. Analytical monitoring parameters have been added to this permit including zinc, iron, nitrate+ nitrite —
nitrogen, and acrylamide. Total nitrogen has been removed.
2. pl: h?�'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 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.
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 2, 4
and 5.
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. 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 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 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.
6. 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.
Any comments should be submitted to the letterhead address no later than thirty (30) days following your
receipt of the draft. If no adverse comments are received from the public or from you, this permit will
likely be issued in approximately two months.
If you have any questions or comments concerning this draft permit, contact me at [phone] or
[e-mail].

Filing the application form along with the requested supplemental information will constitute your application for
renewal of your permit. As stated above, the application form must be completed and returned along with all
requested information by May 4. 2004 in order for the permit to be renewed by October 31, 2004.
Failure to request renewal by May 4, 2004 may result in a civil assessment of at least $500.00. Larger penalties
may be assessed depending on the delinquency of the request. Discharge of stormwater from your facility without
coverage under a valid stormwater NPDES permit would constitute a violation of NCGS 143-215.1 and could
result in assessments of civil penalties of up to $25,000 per day.
If you have any questions regarding the permit renewal procedures please contact Bill Mills of the Stonnwater and

Revised Permit Recommendations: Analytical Monitoring:
1. Maintaining parameters:
a. TSS
b. BOD
c. COD
d. TP
2. Removing parameters:
a. TN
3. Adding parameters...
a. NO3 + NO2 — NSW water. Nitrate + nitrate is a more appropriate measure of bio-available nitrogen.
b. Zn — added due benchmark exceedances at all SDOs during original sampling reported on EPA Form
21'.
c. Fe — added due benchmark exceedances at 4 of 5 SDOs during original sampling reported on EPA
Form 2F.
d. Acrylamide —added for onsite storage, use and air releases and carcinogenic characteristics.
4. pH added — standard addition to permit.
5. All analytical monitoring set to semi-annually.
6. Benchmarks for analytical monitoring and Tiered monitoring system added to this draft permit.
7. Analytical and qualitative monitoring required during representative storm events. Qualitative monitoring
required regardless of representative outfall status.
8. Flow reporting replaced by total rainfall parameter.
9. Vehicle maint monitoring revised to semi-annually. O&O parameter removed. TPH added as replacement.
Other Proposed Changes to the Previous Permit:
1. See draft.permit for full details.
Discussions with permittee: Dick Dunmire, H&S Supervisor, 336-333-3634. 10/21/2009. Ken Miter, El IS
Manager, 336-333-3510, 10/22/2009. Natalie Stennis, Ashland EFIS, 336-335-3778, 10/23/2009.
1. Q: What is your SIC code?
a. ANSWER:2899.
2. Q: Has the facility performed any additional sampling since the latest results on 1/27/09?
a. ANSWER: No, MACTEC consultants advised that no more sampling was required for their permit
following Q2 2009 which was reported as "No Flow".
3. Q: What are your major products?
a. ANSWER: Three main products: super absorbent polymer, skin care products, and concrete additives.
Ashland, Inc. produces water treatment flocculants onsite as well. They work out of Plant-1, Plant-2,
Warehouse-3, and Warehouse-14. This agreement has been in place for a couple years now.
4. Q: Are there any sources of cyanide, fluoride, or selenium onsite?
a. ANSWER: No.
5. Q: According to the renewal package, SDO#I is not associated with industrial activity. Is that still the case?
What area does SDO#I drain? Any explanation for the recent TSS and COD hits?
a. ANSWER: That is correct. This area drains a commercial area with an office building. The elevated
results could be due to road runoff that the outfall receives but would not be associated with our
activities.
6. Q: Do you store or produce any acrylic acid, acrylamide, or acrylonitrilc?
a. ANSWER: Acrylic acid is stored and used onsite. It is reacted with NaOH as part of the process to
produce our super -absorbent polymer. No acrylonitrile. Ashland uses acrylamide for polymer
production. They have two 22,000 gallon tanks in their tank farm.

Dee Freeman
Secretary
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please review the draft
very carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from this facility's current permit:
Analytical monitoring changes:
1. Analytical monitoring parameters have been added to this permit including zinc, iron, nitrate+ nitrite —
nitrogen, and acrylamide. Total nitrogen has been removed.
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 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.
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 2, 4
and 5.
7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall
parameter is in this permit, however.)

Mr. Ken Meyer.
Evonik Stockhausen, Inc.
Permit No. NCS000010
Vehicle maintenance monitoring has been revised to 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 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 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.
6. 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.
Any comments should be submitted to the letterhead address no later than thirty (30) days following your
receipt of the draft. If no adverse comments are received from the public or from you, this permit will
likely be issued in approximately two months.
If you have any questions or comments concerning this draft permit, contact me at [phone] or
[e-mail].

PART H .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 descriptiun of storage practices, Oadimg and unloading activities, outdoor process
areas. dust or particulate gnemt;— or control processes, and waste disposal practices.
(e) 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 111. 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 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 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 with a
Part 11 Page l of 5

Permit No. NCSOOOOIO
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 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.
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. 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
die stormwater aspects of the SPRP. The common elements of the SFCC with the SFR_P 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. Emplovee 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 made.
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 .ystems, plant equipment and systems. Records of these inspections shall be
incorporated into the Stormwater Pollution Prevention Plan.
Part II Page 2 of 5

Permit No. NCS000010
Stormwater discharge characteristic monitoring as required in Part II of this permit shall be performed in
addition to facility inspections.
9. Implementation. The permittee shall document all monitoring, measurements, inspections and maintenance
activities and training provided to employees, including the log of the sampling data and of activities taken
to implement BMPs associated with the industrial activities, including vehicle maintenance activities. Such
documentation shall be kept on -site for a period of five years and made available to the Director or his
authorized representative immediately upon request.
SECTION B: ANALYTICAL MONITORING REQUIREMENTS
During the period beginning on the effective date of the permit and lasting until expiration, the permittee is
authorized to discharge stormwater subject to the provisions of this permit. Analytical monitoring of stormwater
discharges shall be performed as specified below in Table 1.
All analytical monitoring shall be performed during a representative storm event. The required monitoring will
result in a minimum of 4 analytical samplings being conducted over the term of the permit at each stormwater

It shall not be a defense for a permittee in an enforcement action that it would have
been necessary to halt or reduce the permitted activity in order to maintain
compliance with the condition of this permit_
Definitions
(1) 'Bypass" means the known diversion of stormwater from any portion of a
stormwater control facility including the collection system, which is not a
designed or established or operating mode for the facility.
(2) "Severe property damage" means substantial physical damage to property,
damage to the control facilities which causes them to become inoperable, or
substantial and permanent loss of natural resources which can reasonably be
expected to occur in the absence of a bypass. Severe property damage does
not mean economic loss caused by delays in production.
Bypass Not Exceeding Limitations.
The permittee may allow any bypass to occur which does not cause limitations to be
exceeded, but only if it also is for essential maintenance to assure efficient
operation. These bypasses are not subject to the provisions of Paragraphs c. and d.
of this section.
c. Notice
(1) Anticipated bypass. If the permittee knows in advance of the need for a
bypass, it shall submit prior notice, if possible at least ten days before the
date of the bypass; including an evaluation of the anticipated quality and
affect of the bypass.

Individual Stormwater Page Al2
(2) Unanticipated bypass. The permittee shall submit notice within 24 hours of
an unanticipated bypass as required in Part II, E. 5. of this permit. (24-
hour notice).
Prohibition of Bypass
Bypass is prohibited and the Director may take enforcement action against a
permittee for bypass, unless:
(1) Bypass was unavoidable to prevent loss of life, personal injury or severe
property damage;
(2) There were no feasible alternatives to the bypass, such as the use of
auxiliary control facilities, retention of stormwater or maintenance during
normal periods of equipment downtime or dry weather. This condition is
not satisfied if adequate backup controls should have been installed in the
exercise of reasonable engineering judgment to prevent a bypass which
occurred during normal periods of equipment downtime or preventive
maintenance; and
(3) The permittee submitted notices as required under Paragraph c. of this
section.
The Director may approve an anticipated bypass, after considering its adverse
effects, if the Director determines that it will meet the three conditions listed above
in Paragraph d. of this section.

a. Definition
"Upset " means an exceptional incident in which there is unintentional and
temporary noncompliance with technology based permit effluent limitations
because of factors beyond the reasonable control of the permittee. An upset does
not include noncompliance to the extent caused by operational error, improperly
designed treatment or control facilities, inadequate treatment or control facilities,
lack of preventive maintenance, or careless or improper operation.
b. Effect of an Upset.
An upset constitutes an affirmative defense to an action brought for noncompliance
with technology based permit effluent limitations if the requirements of paragraph c.
of this condition are met. No determination made during administrative review of
claims that noncompliance was caused by upset, and before an action for
noncompliance, is final administrative action subject to judicial review.
Conditions Necessary for a Demonstration of Upset
A permittee who wishes to establish the affirmative defense of upset shall
demonstrate, through properly signed, contemporaneous operating logs, or other
relevant evidence that .
(1) An upset occurred and that the permittee can identify the cause(s) of the
upset;

informing you in advance that your permit will be expiring. Enclosed you will find an individual permit renewal
application form, supplemental information request, and Stormwater Pollution Prevention Plan certification.
Filing the application form along with the requested supplimental information will constitute your application for
renewal of your permit. The application form must be completed and returned along with all requested
information within thirty days of receipt of this letter in order to constitute a timely renewal filing.

RECENT CHANGES IN INDUSTRIAL ACTIVITIES AT THE 2401 DOYLE STREET, GREENSBORO
FACILITY
Since 1993 when the last update to the stormwater permit was submitted there have been three major developments that did not
disturb 5 acres but did have significant impact on the plants stormwater outfalls.
1) Added several adjoining properties to the production facility, obtain private ownership of the city streets and fenced in the main
industrial facility. There are now 38 acres in the center production area of the site. Adjoining properties across Patton street that
are not in use add 20 more acres to the facility. This has allowed consolidation of outfalls and improve control of stormwater
quality.
2) A chemical rail unloading station was built on the north east corner of the property. This facility consolidated outfalls 2 and 3
since they were the same water drainage. Outfall 4 was eliminated by reconstruction of the railspur and moved to a new site for
Outfall 3. Outfall 5 and 6 have been consolidated to a new Outfall 4. See attached site drawing.
3) Expansion of Plant 6 and the building of the new rail unloading facility has required the moving of Terrell street and improvement
of the stormwater structure in place in that area to serve the new impervious areas built.
This significant growth is an expansion of existing production capabilities. The production chemistry is similar to what has been the
major activities on this site since 1986.

FUEL OIL STORAGE.
All fuel oil tanks will be stored in a solid containment. All fuel oil in tanks over 1000 gallons are stored in reinforce concrete dikes
designed to hold the capacity of the largest size tank in the containment plus a four inch freeboard.
CHEMICAL TANKS STORAGE
All chemical tanks are installed in reinforced concrete dikes that are sized to handle the largest tank in storage plus a four inch
freeboard. Where materials stored are corrosive to concrete there is a chemical resistant coating in placed and maintained to prevent
corrosion to the containment structure.
UNLOADING ACTIVITIES
OILS:
All unloading of bulk tankers into storage tanks over 1000 gallons take place on a concrete pad with spill containment in the
stormwater drainage area.
1. main yard has four unloading areas. All stormwater culverts in this area drain to a 5000 gallon basin with a 24 inch slide gate cutoff
valve. This valve is closed at all times except during a significant rain event when it is necessary to open the valve to prevent plant
electrical room Flooding.
2. Plant 4 has a 14" trench below the unloading area the drains into the storage dike. This is functional at all times including a
significant rain event.
3. There are curbs or trenches around all natural animal fat oil/fatty acid hot.boxes to contain any spills in drum handling in the central
main operational area.
ACID /CAUSTIC UNLOADING ACTIVITIES;
Acrylic acid and Sodium Hydroxide unloading stations are under a cover and have stormwater bypass and protection trenches to
keep unloading activities from being washed by rain events and the activities being mixed with rainwater. There are two tank truck
facilities and one railcar unloading facility that are designed with rain covering and protective spill reminment of a minimum of one
transportation vehicles contents in a specially covered sump.
SITE OUTFALLS
All site outfalls from production areas will have cut off valves installed to provide a way to keep any spill from leaving the facility
if found in time. The main production area's final outfall area will be improved by removing city street outfall and a retention Swale
installed upstream of the cutoff valve.

November 17,2005
Re: Stockhausen, Inc. - - Individual NPDES Stormwater Permit No: NCS00010
Dear Mr. Bennett:
You and Will Burton, our legal counsel with Smith Moore LLP, previously spoke on the telephone
about the stormwater permitting issues related to a pending multi -stage corporate transaction. As you
requested, we can now share the pertinent details of that transaction with you so that you can confirm
your prior opinion that the existing stormwater permit will remain sufficient following the completion of
this transaction. We would appreciate it if you would treat the information in this letter as confidential as
the nature of this transaction is not publicly known at this time.
Backuround
Stockhausen, Inc. owns and operates a manufacturing complex at 2401 Doyle Street in
Greensboro, North Carolina. Stockhausen currently holds the above -referenced individual stormwater
permit for the stormwater discharges associated with the entire Doyle Street complex. For your
convenience, we have enclosed a schematic showing the existing stormwater discharges from the Doyle
Street complex. Stockhausen NPDES permit renewal is currently with Aisha Lau for processing.
Summary of Transaction
Stockhausen, Inc. is in the process of marketing its global Water Treatment business unit, which
operates out of portions of the Doyle Street complex. To facilitate the proposed sale, a new corporate
entity, Stockhausen, LLC, has been formed to own the assets of the Water Treatment business unit.
Specifically, Stockhausen, LLC owns the production equipment in Plant 1 and Plant 2 and associated
storage tanks and leases from Stockhausen, Inc. the real property and improvements marked on the
enclosed schematic, including production plants 1 and 2, warehouses 3 and 14, office 6, and associated
tank farms.
Stockhausen, Inc. is currently the sole member of Stockhausen, LLC. The final stage of the
transaction is structured so that the purchaser, who has not yet been identified, will acquire
Stockhausen, Inc.'s membership interest in Stockhausen, LLC (which will continue to be the entity
operating the Water Treatment business following the sale). This is expected to occur on or around
#850000

January 1, 2006. Stockhausen, Inc. and Stockhausen, LLC do not anticipate any significant changes in
the nature of Stockhausen, LLC's operations or the composition of its stormwater discharges following
the closing. In addition, the remainder of Stockhausen, Inc.'s operations at the Doyle Street complex will
not be impacted by this transaction.
Stormwater Permitting Approach
Following the sale of its membership interest in Stockhausen, LLC, Stockhausen, Inc. will
continue to own all of the real property at the Doyle Street complex. Therefore, following the sale, our
understanding is that the combined stormwater discharges of Stockhausen, Inc. and Stockhausen, LLC
can continue to be authorized under Stockhausen, Inc.'s existing individual stormwater permit and, if
necessary and appropriate, that Stockhausen, LLC can be added to the permit as a "co-permittee."
Thank you for your consideration of this information. If you need any additional information
related to this matter, please give me or Will Burton (336-378-5421) a call. We look forward to working
with you.
Sincerely,
Alice Wessel man-Rimmer
