Dear Mr. Vancil:
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please
review the draft carefully to ensure thorough understanding of the conditions and
requirements it contains.
The draft permit contains the following significant changes from the facility's current permit:
1. You are required to collect analytical and qualitative monitoring samples during
"measurable storm events" as defined in Part II, Section B. This term is different
from the "representative storm event" in earlier permits.
2. Requirements for the Stormwater Pollution Plan (SPPP) have been updated in Part Il,
Section A.
3. Changes have been made to two monitoring parameters, including a change to one
benchmark. Stormwater benchmarks are not permit limits, but rather guidelines for
implementing the Stormwater Pollution Prevention Plan (SPPP). A benchmark
exceedance is not a permit violation; however, the permittee must respond to
exceedances as directed in the Tiers.
• Vehicle maintenance (Tables 5,6) monitoring parameters have been revised
as follows:
o Non -Polar Oil & Grease [EPA Method 1664 (SGT-HEM)] replaces
Oil & Grease/TPH. This requirement appears in all individual
stormwater permits; however, it only applies to facilities that
perform onsite vehicle maintenance activities. If the facility begins
vehicle maintenance during the permit cycle, the requirements shall
apply.

o pH monitoring is no longer required for discharges only associated
with vehicle maintenance activities.
4. A new section on Special Conditions has been added in Part Il, Section E to comply
with federal regulations requiring electronic submittal of discharge monitoring
reports. This section of the permit will become effective December 21, 2016.
5. Civil and administrative penalty amounts have been updated to reflect current
federal law in Part III, Section A, 2(b) and (g).
Please review the draft permit and submit any comments to me no later than 30 days
following your receipt of the draft. Comments may be emailed to me at
[e-mail] or mailed to my attention at NCDEQ, Land Quality Section,

Best Management Practices for
Storm Water Prevention Plan
Permit NCS000107 Expires 6/30/2013
Stormwater Management Overview
At the Lanxess Greensboro facility, all loading/unloading areas are covered. The areas
behind inside production area LP-2 are primarily for drum and tote filling on both liquid
and molten materials. Filled drums are stored in warehouse by shipping dock. Cast
molten material is stored on racks and shelves prior to being ground to meet customer
specifications. Cast material solidifies quickly while filling and casting in LP 1 or LP2
diked production areas, to prevent spilling to environment.
Drum recycling takes place on contained concrete pad behind LP2. Drum recycling
consists of weak caustic rinse of emptied drums on concrete pad by automated filling
equipment. Caustic in pumped into and out of drum. Concrete pad contains all spill to the
sump, for collection to C6 pretreatment. C6 pretreatment is discharged to City of
Greensboro POTW.
All outside tanks are diked in the event of a spill or leak. Storm water from these dikes is
pumped to collection in C6, prior to discharge to City of Greensboro POTW. Facility has
equipment for recovery in the event of a spill or leak. No spills from the diked tank farms
should ever be released to stormwater drainage system.
Additionally the manufacturing areas designated on the map as (UP-], UP-2. LP-1, and
LP-2, Flammable Storage Warehouse, Finished Product Storage. Centrifuge building, hot
room storage, and Pilot Plot) are all designed to contain accidental spills or leaks to
roadways and storm water discharge.
Spill Prevention and Response Management Overview
The identified potential pollutant sources at Lanxess Greensboro are:
1. Failed or broken valves, transfer lines, or hoses used during loading and
unloading operations.
2. Accidental release of materials from the reactors, such as rupture discs, pressure
relief valves activation, or in the event of attached broken valves or lines.
I Accidental spills of materials while transporting containers between production
and warehouse areas, including the flammable storage building, and the hot room
storage buildings
Daily management walk-arounds are conducted to assess status of tanks and production
equipment. Work orders for needed improvements are recorded in computer system to

track activity. Management will review improvements to ensure they are correctly
performed.
All personnel are trained to immediately inform supervisor or the plant manager in the
event of a spill or threatened spill situation. If unable to immediately contact these
persons. 911 should be dialed to explain the event in full detail including the need for the
Greensboro Fire Department Hazmat Team.
Actions to prevent further spill off on to soil, roadways; or storm water should be
initiated after proper notification and alerts to surrounding personnel. The material
released should be considered for flammability hazards, reportable quantities released,
and environmental hazards associated.
Narrative of Significant Chan ems for
Storm Water Prevention Plan
Permit NCS000107 Expires 6/30/2013
Significant changes for Lanxess Greensboro:
Lanxess Corp. (DAX: LXS) acquired Greensboro site on October 17th 2011 from
privately held Unitex Chemical Corporation. Lanxess has invested in upgraded existing
equipment, process automation, and safety training and awareness. The Greensboro site is
also seeking certification to compliance with Responsible Care 14001 standard.
Zoning permits from the City of Greensboro have been granted for parking lot expansion
currently under way. Permits for future tank farm expansion are expected in the near
future.
Lanxess Corp has contracted SE Technologies, Pittsburgh, PA to upgrade existing
SWPPP and SPCC plans by a certified PE.

2008 'and expired on June 30, 2013. The facility applied for renewal prior to expiration as
required and has been operating under the existing guidelines while waiting for new permit
coverage. A copy of the permit is required to be maintained with the Stormwater Pollution
Prevention Plan (SPPP) documents. It was available for review.
Records/Reports:
This facility was required to develop and maintain a Stormwater Pollution Prevention Plan
(SPPP) in accordance with Part II, Section A of the permit. The SPPP along with monitoring
and training records need to be updated annually. The SPPP is maintained in a computer system
that is accessible at the facility and by those at the Pennsylvania office and the main office in
Cologne, Germany. Documents are updated annually and are complete including individual
pen/ink signatures for each person participating in safety and stormwater training.
Nothing Compares.

Facility Site Review:
This facility produces plasticizers and flame retardants as well as other chemical agents. The
plant is under 24-hour surveillance with security and facility staff monitoring around the clock.
There are three (3) alarms. One is for fire, one is for chemical spills and the other sounds if a
disk ruptures.
One area of the site has monitoring wells. A measure incorporated as part of groundwater/soils
clean-up following a wastewater collection tanks collapse prior to Lanxess acquisition'from
Unitex.
A Pilot Plant has been removed, parking lot additions have taken place and a new tank farm has
been installed since the latest siteplan was done. Please update the siteplan to include these
changes during the next annual update.
The facility has several tank farms. Some contain raw materials while others contain finished
chemical products. All tanks are contained in tank farms with secondary containment. All
process industrial water is pumped to City of Greensboro Wastewater Treatment Plant for
treatment. Everything is done to avoid the possibility of wastewater entering the stormwater
system.
Effluent Receiving Waters:
Stormwater from this facility empties into an unnamed tributary of South Buffalo Creek, Class
w�J A NSW of the Cape Fear River Basin.
Self -Monitoring Program:
The plant has two (2) outfalls. Both storm drain lines have a valve that can be closed in the
event of a spill to allow clean-up to take place without contamination of stormwater. If a spill
requiring assistance were to occur, the Plant Manager or HSEQ Coordinator would contact Clean
Harbor to perform clean-up and would contact the City of Greensboro Stormwater and NCDEQ
for notification as required.
Both qualitative and analytical monitoring,are required to be conducted twice annually at each
outfall. Monitoring has been performed as required. Samples are se t to Pace Analytical. All yL
monitoring is up to date and within required parameters. 1� }"3�`"�
This inspection was conducted as part of the renewal process for Individual Stormwater Permit
coverage at this facility. The remaining time expected to complete the permitting process will be
approximately 45 days which includes a 30 day Public Notice period and your opportunity to
review the draft permit before the final is issued.

Dear Mr. Vancil:
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please
review the draft carefully to ensure thorough understanding of the conditions and
requirements it contains.
The draft permit contains the following significant changes from the facility's current permit:
You are required to collect analytical and qualitative monitoring samples during
"measurable storm events" as defined in Part II, Section B. This term is different
from the "representative storm event" in earlier permits.
2. Requirements for the Stormwater Pollution Plan (SPPP) have been updated in Part II,
Section A.
3. Changes have been made to two monitoring parameters, including a change to one
benchmark. Stormwater benchmarks are not permit limits, but rather guidelines for
implementing the Stormwater Pollution Prevention Plan (SPPP). A benchmark
exceedance is not a permit violation; however, the permittee must respond to
exceedances as directed in the Tiers.
+ Vehicle maintenance (Tables 5,6) monitoring parameters have been revised
as follows:
o Non -Polar Oil & Grease [EPA Method 1664 (SGT-HEM)j replaces
Oil & Grease/TPH. This requirement appears in all individual
stormwater permits; however, it only applies to facilities that
perform onsite vehicle maintenance activities. If the facility begins
vehicle maintenance during the permit cycle, the requirements shall
apply.

1612 Mail Service Center 1 512 North Salisbury Street I Raleigh, NC 27699-1612
919 707 9200 T

o pH monitoring is no longer required for discharges only associated
with vehicle maintenance activities.
4. A new section on Special Conditions has been added in Part II, Section E to comply
with federal regulations requiring electronic submittal of discharge monitoring
reports. This section of the permit will become effective December 21, 2016.
5. Civil and administrative penalty amounts have been updated to reflect current
federal law in Part III, Section A, 2(b) and (g).
Please review the draft permit and submit any comments to me no later than 30 days
following your receipt of the draft. Comments may be emailed to me at

PART II MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The permittee shall develop and implement a Stormwater Pollution Prevention Plan
(SPPP). The SPPP shall be maintained on site unless exempted from this requirement by
the Division. The SPPP is public information in accordance with Part Ill, Standard
Conditions, Section E, paragraph 3 of this permit. The SPPP shall include, at a minimum,
the following items:
1. Site Overview. The Site Overview shall provide a description of the physical facility
and the potential pollutant sources that may be�expected,to contribute to
contamination of stormwater discharges. The Site OVerviewshall contain the following:
(a) A general location map (USGS quadrangle. ap arappropriately drafted equivalent
15
map), showing the facility's location in relation to transportation routes and surface
/ - ``w
waters; the name of the receiving waters to.which the stormwater outfalls
discharge, or if the discharge is to a -municipal separate storm sewer system, the
name of the municipality and the. uttimate receiving waters; and accurate latitude
and longitude of the points.of stormwater discharge associated with industrial
activity. The general location,map (or alternatively the site map) shall identify
whether any receiving waters are impaired (on the states 303(d) list of impaired
waters) or if the site is'located.m a watershed for which a TMDL has been
established, and what the parameters of concern are.
(b) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices. A narrative description of the potential pollutants that
could be expected to be present in the stormwater discharge from each outfall.
(c) A site map drawn at a scale sufficient to clearly depict: the site property boundary;
the stormwater discharge outfalls; all on -site and adjacent surface waters and
wetlands; industrial activity areas (including storage of materials, disposal areas,
process areas, loading and unloading areas, and haul roads); site topography and
finished grade; all drainage features and structures; drainage area boundaries and
total contributing area for each outfall; direction of flow in each drainage area;
industrial activities occurring in each drainage area; buildings; stormwater Best
Management Practices (BMPs); and impervious surfaces. The site map must
indicate the percentage of each drainage area that is impervious, and the site map
must include a graphic scale indication and north arrow.
(d) A list of significant spills or leaks of pollutants during the previous three (3) years
and any corrective actions taken to mitigate spill impacts.
Part II Page 1 of 15

Permit No. NCS000107
(e) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The permittee shall re -certify annually 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 Strategy. The Stormwater Management Strategy shall
contain a narrative description of the materials management practices employed which
control or minimize the stormwater exposure of significant materials, including
structural and nonstructural measures. The Stormwater Management Strategy, at a
minimum, shall incorporate the following:
(a) Feasibility Study. A review of the technical and econoinic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to rainfall and run on-flow\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, this review shall document -the feasibility of diverting the stormwater
run-on away from areas of potentiacontamination.
(b) Secondary Containment Requirements and Records. Secondary containment is
required for: bulk storage_ of liquid materials; storage in any amount of Section 313
of Title III of the Superfun&Aniend'ments and Reauthorization Act (SARA) water
priority chemicals; and storage�in any amount of hazardous substances. in order to
prevent leaks and spills from �contaminating stormwater runoff. A table or summary
of all such tanks and/Stored materials and their associated secondary containment
areas shall be maintained.,If the secondary containment devices are connected to
stormwater conveyance -systems, the connection shall be controlled by manually
activated valves or other similar devices (which shall be secured closed with a
locking mechanism). Any stormwater that accumulates in the containment area
shall be at a minimum visually observed for color, foam, outfall staining, visible
sheens and dry weather flow, prior to release of the accumulated stormwater.
Accumulated stormwater shall be released if found to be uncontaminated by any
material. Records documenting the individual 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 (S) years. For facilities subject to a federal oil Spill
Prevention, Control, and Countermeasure Plan (SPCC), any portion of the SPCC Plan
fully compliant with the requirements of this permit may be used to demonstrate
compliance with this permit.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMPs) shall be provided. The installation and implementation of BMPs
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and on data collected
through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMP Summary shall be reviewed and updated annually.
Part II Page 2 of 15

Permit No. NC5000107
3. Spill Prevention and Response Procedures. The Spill Prevention and Response
Procedures (SPRP) shall incorporate an assessment of potential pollutant sources based
on a materials inventory of the facility. Facility 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
increased 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 and implemented.
The program shall address all stormwater control systems (if applicable), stormwater
discharge outfalls, all on -site and adjacent surface waters and wetlands, industrial
activity areas (including material storage•areas, material handling areas, disposal areas,
process areas, loading and unloading areas,�and)haul roads), all drainage features and
structures, and existing structural BMPs. The program shall establish schedules of
inspections, maintenance, and housekeeping activities of stormwater control systems,
as well as facility equipment, facility areas, and facility systems that present a potential
for stormwater exposure o,!�stormwater pollution where not already addressed under
another element of the SPPP. Inspection of material handling areas and regular
cleaning schedules of these areas`,shall be incorporated into the program. Timely
compliance with the estabi lished schedules for inspections, maintenance, and
housekeeping shall be recorded and maintained in the SPPP.
S. Facility Inspections. Inspections of the facility and all stormwater systems shall occur
as part of the Preventative Maintenance and Good Housekeeping Program at a
minimum on a semi-annual schedule, once during the first half of the year (January to
June), and once during the second half (July to December), with at least 60 days
separating inspection dates (unless performed more frequently than semi-annually).
These facility inspections are different from, and in addition to, the stormwater
discharge characteristic monitoring at the outfalls required in Part I1 B, C, and D of this
permit.
6. 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.
7. Responsible Party. The SPPP shall identify a specific position or positions responsible
for the overall coordination, development, implementation, and revision of the SPPP.
Part II Page 3 of 15

Permit No. NCS000107
Responsibilities for all components of the SPPP shall be documented and position
assignments provided.
8. SPPP Amendment and Annual Update. 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:
(a) an updated list of significant spills or leaks of pollutants for the previous three
(3) years, or the notation that no spills have occurred (element of the Site
Overview);
(b) a written re -certification that the stormwater outfalls have been evaluated far
the presence of non-stormwater discha ges'.(element-of the Site Overview);
(c) a documented re-evaluation of the e`ffecttveness.of'the on -site stormwater
BMPs (BMP Summary element of th Stormwater Management Strategy).
(d) a review and comparison of sample. analyticandata to benchmark values (if
applicable) over the past year„including a�discussion about Tiered Response
status. The permittee shall.us/e the/Division's Annual Summary Data
Monitoring Report (DMR) =available from the Stormwater Permitting
Program's website•(See"MnitringForms' here:
1
The Director may notify the permittee when the SPPP 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 SPPP 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

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 measureable storm event at each
stormwater discharge outfall (SDO). Only SDOs discharging stormwater associated with
industrial activity must be sampled (See Definitions).
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 DEMLR Regional Engineer. See Definitions.

sampling) during a measureable.storm event, until either another permit is issued for this facility or until
this permit is revoked or rescinded!if the facility is monitoring monthly because of Tier Two or Three
response actions under the previous permit, the facility shall continue a monthly monitoring and
reporting schedule in Tier Two or Tier Three status until relieved by the provisions of this permit or
the Division.
2 Grab samples shall be collected within the first 30 minutes of discharge. When physical separation between
outfalls prevents collecting all samples within the first 30 minutes, sampling shall begin within the first 30
minutes, and shall continue until completed.
3 Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless
representative outfall status (ROS) has been granted. A copy of the Division's letter granting ROS shall be
kept on site.
4 For each sampled measureable storm event, the total precipitation must be recorded. An on -site rain gauge
is required. Where isolated sites are unmanned for extended periods of time, a local rain gauge reading
may be substituted for an on -site reading.
The permittee shall complete the analytical samplings in accordance with the schedule
specified below in Table 2, unless adverse weather conditions prevent sample collection
(see Adverse Weather in Definitions). Sampling is not required outside of the facility's
normal operating hours. A minimum of 60 days must separate Period 1 and Period 2
sample dates, unless monthly monitoring has been instituted under a "Tier Two"
response. Inability to sample because of adverse weather conditions must be documented
Part II Page 5 of 15

Permit No. NC5000107
in the SPPP and recorded on the DMR. The permittee must report the results from each
sample taken within the monitoring period (see Part III, Section E). However, for purposes
of benchmark comparison and Tiered response actions, the permittee shall use the
analytical results from the first sample with valid results within the monitoring period.

1 Maintain semi-annual monitoring until either another permit is issued for this facility or until this
permit is revoked or rescinded: The permittee mu t submit an application for renewal of coverage
before the submittal deadline,(180 days before expiration) to be considered for renewed coverage
under the permit. The permittee must continue analytical monitoring throughout the permit
renewal process, even if a renewal -permit is not issued until after expiration of this permit.
2 If no discharge occurs during the sampling period, the permittee must submit a monitoring report
indicating "No Flow' or/"No Discharge" within 30 days of the end of the sampling period.
Failure to monitor semi-annually permit terms may result in the Division requiring
monthly monitoring for all parameters for a specified time period. "No discharge" from an
outfall during a monitoring period does not constitute failure to monitor, as long as it is
properly recorded and reported.
The permittee shall compare monitoring results to the benchmark values in Table 3.
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. See below the descriptions of Tier One, Tier Two, and
Tier Three response actions below. In the event that the Division releases the permittee from
continued monthly monitoring and reporting under Tier Two or Tier Three, the Division's
release letter may remain in effect through subsequent reissuance of this permit, unless the
release letter provides for other conditions or duration.

is not a permit violation; however, failure to respond to the exceedance as outlined in this
permit is a violation of permit conditions. N�
Tier One
If: The first valid sampling results are above a benchmark val\;. r outside of the benchmark range, for any
parameter at any outfall;
Then: The permittee shall: /��� '\_/J
1. Conduct a stormwater management inspection of: the, facility within two weeks of receiving sampling
results. /f �1 /! :7)
2. Identify and evaluate possible causes of the benchmark value exceedance.
3. Identify potential, and select the specific feasible: source controls, operational controls, or physical
improvements to reduce concentrations of he parameters of concern, and/or to bring concentrations
within the benchmark range.
4. Implement the selected feasible actioons,within two months of the inspection.
S. Record each instance of a Tier One response in the SPPP. Include the date and value of the benchmark
exceedence, the inspection date, -the personnel conducting the inspection, the selected actions, and the
date the selected actions were implemented.
6. Note: Benchmark exceedances for a different parameter sevarately triQeer a tiered response.
Tier Two
If: The first valid sampling results from two consecutive monitoring periods (omitting periods with no
discharge) are above the benchmark values, or outside of the benchmark range, for any specific parameter at
a specific dischar a outfall;
Then: The permittee shall:
1. Repeat all the required actions outlined above in Tier One.
2. Immediately institute monthly monitoring and reporting for all parameters. The permittee shall conduct
monthly monitoring at every outfall where a sampling result exceeded the benchmark value for two
consecutive samples. Monthly (analytical and qualitative) monitoring shall continue until three
consecutive sample results are below the benchmark values or within benchmark range.
3. If no discharge occurs during the sampling period, the permittee is required to submit a monthly
monitoring report indicating "No Flow' to comply with reporting requirements.
4. 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.
S. Maintain a record of the Tier Two response in the SPPP.
6. Continue Tier Two response obligations throughout the permit renewal process.
Part 11 Page 7 of 15

Permit No. NCS000107
Tier Three
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 notify the DEMLR Regional Engineer in writing within 30 days of receipt of the fourth
analvtical results:
Then: The Division may but is not limited to:
• require that the permittee revise, increase, or decrease the monitoring and reporting frequency for
some or all of the parameters herein;
• require sampling of additional or substitute parameters;
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures;
• require the permittee to perform upstream and downstream monitoring to characterize impacts on
receiving waters; or
• require the permittee implement site modification to:qual fyfor a No Exposure Exclusion;
• require the vermittee to continue Tier Three oblieations:throuah_the-vermit renewal arocess.
This site discharges to impaired waters experiencing problems with biological integrity,
turbidity, and ammonia. A Total Maximum Daily/Load-(TMDL) is approved for this segment
of South Buffalo Creek. As such, the permittee may be required to monitor for the
pollutant(s) of concern in the future and/submit_ results to the Division. 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 neede�achievet 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.
SECTION C: QUALITATIVE MONITORING REQUIREMENTS
The purpose of qualitative monitoring is to evaluate the effectiveness of the Stormwater
Pollution Prevention Plan (SPPP) and identify new potential 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 monitoring per the Qualitative Monitoring
Response, below). Inability to monitor because of adverse weather conditions must be
documented in the SPPP and recorded on the Qualitative Monitoring Report form (see
Adverse Weather in Definitions). Only SDOs discharging stormwater associated with
industrial activity must be monitored (See Definitions).
Part ll Page 8 of 15

Permit No. NCS000107
In the event an atypical condition is noted at a stormwater discharge outfall, the permittee
shall document the suspected cause of the condition and any actions taken in response to
the discovery. This documentation will be maintained with the SPPP.

(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.
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.
Part ll Page 9 of 15

Permit No. NC5000107
Qualitative Monitoring Response
Qualitative monitoring is for the purposes of evaluating SPPP effectiveness, identifying new potential
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 standard violation, the
Division may but is not limited to:
• require that the permittee revise, increase, or decrease the monitoring frequency for some
or all parameters (analytical or qualitative)
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures;
• require the permittee to perform upstream and downstream monitoring to characterize
impacts on receiving waters; or
• require the permittee implement site modifircaattions� oualify for a No Exposure Exclusion.
SECTION D: ON -SITE VEHICLE MAINTENANCE,MONI ORING REQUIREMENTS
Facilities that have an vehicle maintenance cactivity"occurring on -site which uses more
than S5 gallons of new motor'oil per month when averaged over the calendar year
shall perform analytical monitortng,asspecified below in Table S. All analytical
monitoring shall be performed during•a measureable storm event at all stormwater
discharge outfalls (SDOs) that discharge stormwater runoff from vehicle maintenance areas,

Impairments and Basinwide Recommendations: This site is in a watershed with multiple urban influences .
(along a very populated corridor of I-85), and South Buffalo Creek suffers from several impacts of this
urbanization. The stream is filled with debris, and the banks are eroded. This creek has had problems with
fluoride, cyanide, selenium (TMDL developed for these pollutants), as well as turbidity (2006 Impaired Waters
[303(d)] List), and it remains on the current draft 303(d) List for impaired biological integrity. There was no
information readily available about the TMDL approved for this creek in 1997; however, this facility should not
be a point source of fluoride, cyanide, or selenium.
The Metro (T.Z. Osborne) WWTP (NC0047384) discharges further downstream of Unitex Chemical and has
had significant cyanide permit limit violations in the past. The Unitex facility is also inside Greensboro, whose
MS4 was permitted as part of the Phase I stormwater regulations.
The Cape Fear Basinwide Plan recommends that the city of Greensboro continue to monitor water quality in
South Buffalo Creek, and that DWQ continue to work with the City to identify measures for reducing
stormwater impacts to the creek. The facility does not discharge to Greensboro's MS4, but Greensboro's efforts
could still affect the site.
4. Threatened and Endangered: None identified in NC Natural Heritage Program Virtual Workroom GIS database
(Queried 4/2/2008).
Page 3of8

NCS000107
5. Location: Facility is within Greensboro, near I-40 and US-29, northwest of South Buffalo Creek.
6. Industrial Changes Since Previous Permit: During the previous permit term, there have been installations of new
buildings, a new line inside the process plant, and new process components (e.g., distillation column).
Wastewater piping and equipment have also been modified. Notable industrial process change: liquid phthalate
plasticizer manufacture has ceased at this plant. See discussions with penmittee about current industrial
activities.
Chemicals Stored: Company submitted list of chemicals stored (see excerpt from Accidental Discharge Plan,
attached). A variety of organics (including alcohols and solvents), sulfonamides, caustics, fuel oil, etc. are listed.
All tank areas diked and alarmed, and only one loading area is uncovered (which drains to sump with ability to
pump to POTW). These areas do not appear to pose a large concern for stormwater contamination given the
facility's storage practices and ability to contain/divert spills. Chemical Oxygen Demand (COD) and pH are
appropriate indicators for problems during this permit term. Future reviewers may consider removing at the next
renewal if values are consistently below benchmarks, unless these parameters are deemed useful for continued
vigilance.
Anal3jical Monitoring Notes: There was quarterly monitoring of total nitrogen required in the fourth year of the
permit only. Company monitored/reported TKN instead (nitrates/nitrite concentrations not included) for four
sampling periods. TKN concentrations were well below benchmark of 20 mg/l, but no reason to expect high
levels of nitrate/nitrite concentrations. See Table 1. The last sample was just outside the final quarter dates.
Continued nitrogen (TN) monitoring is not recommended. There is no phosphorus data to date, but also no
apparent sources —no TP monitoring recommended.
9. Qualitative Monitoring Notes: No problems noted.

Revised Permit Recommendations: Analytical Monitoring:
1. Chemical Oxygen Demand (COD benchmark 120 mg/1), o-Xylene (benchmark 4.03 mg/1), and pH (within 6-
9, standard when any monitoring required) have been added to the analytical monitoring requirements. COD is
a good general surrogate for identifying contamination from the types of materials stored here —particularly at a
business where specialty organic chemical products change periodically depending on market demand. Xylcne
is a prominent chemical stored, used, and reported in the TRI (o-xylene is the specified isomer, boiling point
144.50 C) and is not as volatile as the alcohols stored on site. However, sufficient data below the benchmark
would justify removing xylene monitoring during the next permit term. COD and pH may continue to be useful
indicators in future permit terms or may not be necessary.
2. Total Suspended Solids (TSS) and Total Recoverable Zinc arc proposed in the EPA draft 2006 Multi -Sector
Permit for this industry category (which is very broad). However, the reviewer does not see a basis to introduce
those parameters in the renewal permit at this time. There are no noted solids problems and no sources of zinc in
the materials used here.
3. All analytical monitoring has been set to semi-annually during a representative storm event as defined in Part Il
Section B. The permittee must also document the total precipitation for each event. If no discharge occurs
during the sampling period, the permittee must submit a monitoring report indicating "No Flow" within 30 days
of the end of the six-month sampling period. Additionally, samples must be taken a minimum of 60 days apart,
as specified in Table 2.
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 response guidelines in the permit.
5. The permittee is required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part II Section B. Qualitative monitoring is required regardless of representative
outfall status.
6. Permittee responsible for all monitoring until the renewal permit is issued (see Footnotes of Tables 1, 4, and 5).
7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall and event
duration parameters are in this permit, however.)
8. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Other Proposed Changes to the Previous Permit:
1. Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants in each
outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of significant
spills that have occurred in the past three years and also must certify that the outfalls have been inspected to
ensure that they do not contain non-stormwater discharges. Additional information is provided in Part II Section
A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part II Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part 1I 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.

Discussions with permittee: Dr. Jim Day, [phone], April 3, 2008:
1. Q: Facility ceased making phthalates some time ago. What does this site manufacture now?
a. ANSWER: Mostly additives for plastics. There are three main categories of products: (1) flame
retardants for plastics (e.g., wiring), (2) plasticizers for nylon (e.g., sulfonamide -based chemicals that
make nylon more flexible for use in fuel hoses, for example), and (3) orefins used in paper and
cosmetics.
2. Q: What is stored and loaded/unloaded outside?
a. ANSWER: All tank farms are diked and alarmed; major raw materials stored are things like ethyl
hexanol, xylene, and finished products. Will send flow plan submitted to City as part of SIU
requirement that will show all materials stored [attached].
3. Q: Is there a list of chemicals stored on site?
a. ANSWER: Yes, the company maintains this information for its SIU (Significant Industrial User) permit
with the City. Will send a copy [excerpt attached].

Spill and Leak Prevention Equipment and Procedures
At Unitex, all loading/unloading areas are covered, with the exception of the Tankwagon
unloading area behind the LP-2 Production area. The area behind LP-2 is used for
different operations. Loading products straight from reactors to a tanker. This area is also
used to unloading molten materials that solidify quickly upon cooling and present
minimal danger to sewer/storm water contamination. In addition, the area has sloped
drainage to sumps, which empty into the wastewater collection tank for ultimate
discharge to the Publicly Owned Treatment Works (POTW). All manufacturing areas are
covered to prevent exposure to sewer/storm water.
All outside storage tanks are diked with connections only for recovery of material in the
event of a spill or for discharge to the POTW. No discharges from the diked areas shall
be released to the storm water drainage system.
The manufacturing areas (UP-1, UP-2, LP-1, LP-2), flammable storage warehouse, drum
storage heated warehouse, centrifuge building, and pilot plant are designed to contain
accidental spills or leaks and prevent their run off to the outside. All of these areas have
controlled drainage systems and must be manually pump by personnel.
Raw material and finished products at Unitex are stored in enclosed warehouses or other
covered plant areas, or in bulk storage tanks. All bulk storage tanks are contained in
concrete diked areas that have no direct outlets to the sewer system/storm sewer. Bulk
materials are unloaded/loaded into/from tank trucks under a covered loading station
through stainless steel transfer lines to designated storage tanks or directly into the
manufacturing equipment. Drummed, bagged, or other non -bulk materials are
load/unloaded at shipping/receiving docks and are not exposed to storm water/sewer.
Prevention of contaminants into the sewer/storm water system at Unitex will be
accomplished by inspection of all operating equipment, storage areas, storage tanks, and
loading/ unloading areas for leaking lines, valves, and associated equipment. This shall
be done in conjunction with the monthly inspections conducted by the Maintenance
Department and documented on the inspection reports. Also, each shift supervisor has a
walk through the plant a minimum of twice during their shift looking at the equipment in
all areas of the plant. The plants personal are constantly walking through the plant while
doing their job and are instructed to report anything that looks out of the ordinary. The
Unitex facility is inspected by an outside security service and by
supervisory/administrative personnel during weekends, holidays, and other shutdown
periods for general conditions of the facility, including spills and leaks.
Another way the Unitex tries to reduce accidental spills is the use of transfer sheets. The
operator to ensure that material transferred to/from the bulk storage tanks will
accommodate the amount being transferred to the tank/reactor uses a transfer sheet. This
sheet must be reviewed and signed off by the shift supervisor and the operator that is
making the transfer.
Issue Date: 2118108 Supersedes: 8/29/06

Daily washing down the production areas, so that spilled materials will not be "tracked"
outdoors for potential sewer/storm water contamination.
All spills within the facility, including driveways, loading/unloading areas, and diked
areas shall be immediately cleaned up for proper disposition, as directed by the Plant
Manager. Absorbent materials are maintained on -site for use in cleaning up spills (e.g.,
"floor" absorbent, pigs).
Emergency Response Equipment and Procedures
Emergency Equipment
There are multiple radios located with key personal through out the plant during all
operation hours. The plant manager and the environmental manager also have beepers in
order to be contacted after hours.
All tank farms are contained inside concrete dikes and the pumps inside the tank farms
pump to a central controlled tank (C6). All tanks have level alarms that sound inside and
outside the plant at 70% and 80% capacity.
All drains inside the operation areas drain to a central controlled location. If material is
spilled inside the warehouses and the production areas, there are floor drains and sloped
floors to keep the material inside the building. There is floor dry absorbent material
located in Flammable storage warehouse, S-l; S-3, and P-3/Centrifuge building in order
to absorb spills and to prevent material from entering unwanted areas. There are also
PIGS in S-1 to contain small spills.
All plant personnel are trained in the use of protective equipment and are issued a
respirator. These respirators are located in the employees' lockers. Certain personnel are
trained in the use of SCBA type respirator. These respirators are located in S-2 and the
Stripper shack near gate 1.
The plant is equipped with ventilation fans through out the facility. These ventilation
fans are usually running during normal plant operations.
There are two first aid kits available to plant personnel during operational hours. One is
in S-2 near the Quality Coordinators' Office and the other is in the maintenance shop
near tank farm E.

Procedures:
Raw material and finished products at Unitex are stored in enclosed warehouses or other
covered plant areas, as well as in bulk storage tanks. All bulk storage tanks are contained
in concrete diked areas that have no direct outlets to the storm sewer/ sewer. Bulk
materials are unloaded/loaded into/from tank trucks under a covered loading station
through stainless steel transfer lines to designated storage tanks or directly into the
manufacturing equipment with the exception of the aforementioned area behind LP-2.
These areas has sloped drainage to sumps, which empty into the wastewater collection
tank for ultimate discharge to the Publicly Owned Treatment Works (POTW).
Drummed, bagged, or other non -bulk materials are load/unloaded at shipping/receiving
docks and are not exposed to storm sewers/sewers.
Any person in the Unitex Facility, upon discovery of a spill shall immediately inform his
shift supervisor or the Plant Manager. The Plant Manager or his designate is responsible
for spills assessment and will coordinate the clean-up efforts. Actions to prevent run-off
of the spill shall be initiated promptly. In case of a small spill, absorbent material (stored
in the flammable storage warehouse, product storage area S-2, product storage area S-3,
and P-3/Centrifuge area) will be placed on the spill and shoveled into drums for disposal
at a licensed waste disposal facility for hazardous material. Nonhazardous waste is
disposed of to permitted secure landfills, permitted Waste Disposal Facilities, or through
BFI; dumpsters are on -site for such collection for disposal through BFI. Nonhazardous
waste that is acceptable to the sanitary landfill is shipped to the Greensboro landfill. In
case of a large spill, the material will be contained within the plant area, pumped into a
licensed hazardous waste tanker and hauled to a licensed waste disposal site. A spill of
non -hazardous material shall be evaluated, with the assistance and concurrence of the
POTW, for discharge to the POTW. If this is not allowed, the contaminated water shall
be pumped into one or more of the diked areas for disposal, as determined appropriate by
environmental management, plant management and corporate management, and in
accordance with all local, state, and federal regulations. Only those personnel who have
received training to first responder level shall be allowed to remediate, or otherwise
handle, hazardous materials resulting from an incident.
If evacuation is needed, the fire alarm will be pulled to indicate an evacuation is
necessary. All employees hearing the alarm will immediately initiate emergency
shutdown of process equipment and proceed by the nearest safe exit to the easterly
parking lot entrance (Gate Number 1) on Broome Road (atmospheric conditions
permitting, see wind direction by observing wind sock on SR-1720 Alcohol Distillation
Column). The Emergency Coordinator will immediately conduct a roll call to determine
if all Unitex personnel, contractor employees, and visitors are accounted for. An
employee roster is located in the "MSDS" orange storage box at Gate 1. If possible,
visitor logs shall be retrieved from the facility for verification that all on -site personnel
are accounted for. All persons will remain at Gate Number 1 for further instructions
from the Emergency Coordinator or the Emergency Management Representative.

manufacturing or fueling o peratirons., n areas where elimination of exposure is
not practical, the stormwater, management plan shall document the feasibility of
diverting the stormwater run way from areas of potential contamination.
b. Secondary Conta"ir me Requirements and Records. Secondary containment is
required for: bulk storage of liquid materials; storage in any amount of Section
313 of Title III Okthe;Superfund Amendments and Reauthorization Act (SARA)
water priority'chemicals; and storage in any amount of hazardous substances to
prevent leaks and spills from contaminating stormwater runoff. A table or
summary of all such tanks and stored materials and their associated secondary
containment areas shall be maintained. if the secondary containment devices' are
connected directly to stormwater conveyance systems, the connection shall be
controlled by manually activated valves or other similar devices which shall be
secured closed with a locking mechanism, and any stormwater that accumulates in
the containment area shall be at a minimum visually observed for color, foam,
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 (5) years.
C. BMP Summary. A narrative description shall be provided of Best Management
Practices (BMPs) to be considered such as, but not limited to, oil and grease

significant quantities of pollutants to stormwater discharges and data collected
through monitoring of stormwater discharges.
Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or team) responsible for implementing the
SPRP shall be identified. A responsible person shall be on -site at all times during facility
operations that have the potential to contaminate stormwater runoff through spills or
exposure of materials associated with the facility operations. The SPRP must be site
stormwater specific. Therefore, an oil 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 Housekeep g%Progra n.­A preventative
maintenance program shall be developed. The,program shall document schedules of
inspections and maintenance activities of stormwate`r,control systems, plant equipment

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
and that is preceded by at least 72 hours in which no storm event measuring greater than 0.1
inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation. For example, if it rains for 2 hours without producing any collectable discharge,
and then stops, a sample may be collected if a rain producingdischarge begins again within the
next 10 hours.

Dear Dr. Day:
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Several of these changes reflect
the Division's revised strategy for all stormwater renewal permits. 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:
• Total Nitrogen (TN) monitoring has been removed from Part II, Sec. B.
• Chemical Oxygen Demand (COD), o-Xylene, and pH monitoring have been added Part II, Sec. B, based
on the types of materials stored at this facility.
All analytical monitoring has been set to semi-annually during a representative storm event as defined
in Part II, Sec. B. If no discharge occurs during the sampling period, you 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. This schedule also applies to
monitoring triggered by vehicle maintenance activities. This change reflects the Division's revised
strategy for renewal permits and makes stormwater sampling frequency consistent with qualitative
monitoring. -
The Division has incorporated benchmark values into the permit. These benchmarks are not 12ermit
limits. However, exceedences 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 tiered responses
outlined in the permit.
• Total Flow monitoring has been removed. The permit still requires Total Rainfall amount be recorded
for each sampling event. This change is also based on the Division's revised strategy for stormwater
monitoring in renewal permits. Please note that the Stormwater Pollution Prevention Plan (SPPP) site
map must include drainage area for each outfall in acres and the percentage of each drainage area that
is impervious (see Part II, Sec. A).
+ Qualitative monitoring must now be performed during the analytical monitoring event (i.e., during a
representative storm event). §'9r Carolina

Part II, Sec. B.

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 the first 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

Permit Number NCS000107

Dear Permtttee:
Your facility is currently covered for stormwater discharge under NPDES Permit NCS000107. This permit
expires on 6/30/2013. To assure consideration for continued coverage under your individual permit, you
must apply to the Division of Water Quality (DWQ) for renewal of your permit. Enclosed you will find an
individual permit Renewal Application Form, Supplemental Information request, and Stormwater Pollution
Prevention Plan Certification for your facility.
Filing the application form along with the requested supplemental information will constitute your
application for renewal of this permit. Until your permit renewal is completed and you receive a new permit,
please continue to comply with all conditions and monitoring requirements in your expired NPDES
stormwater permit.
Please comlete and return the application and supplemental information to DWQ by April 5. 2 1 . Failure to
request renewal within this time period may result in delay of your permit renewal. Discharge of stormwater
from your facility without coverage under a valid stormwater NPDES permit would constitute a violation of
NCGS 143-215.1 and could result in assessments of civil penalties of up to $25,000 per day.
If you have any questions regarding permit renewal procedures please contact Bradley Bennett of the
Stormwater Permitting Unit at (919)-807-6378 or [e-mail].

Bradley Bennett, Supervisor

Hi Jim,
These are great questions. 1. Test methods should be EPA methods in accordance with
40 CFR 136. Your lab may already be familiar with these, but a good source of
information is on our lab's website:
http://h2o.enr.state.nc.us/lab/downioad.htm
2. Technically, no, a certified lab is not required for stormwater-only discharges
(NC Certification Rules don't apply). However, the methods for analyzing the samples
still need to be in accordance with EPA methods (per federal NPDES rules). As long
as your lab can conform to those (and pH is measured within the 15-minute holding
time), Unitex will be in compliance with analytical monitoring requirements under its
stormwater permit. If not, an NC certified lab will perform those tests in
accordance with the correct methods.
3. Monitoring forms are available on our website
(http://h2o.enr.state.nc.us/su/Forms Documents.htm#miscforms). We are about to
update the Qualitative Monitoring form, so you may want to check back after your
permit has been finalized.
4. The drainage area for each outfall should be determined with the aid of your site
map records and topo grades. I'd recommend looking at EPA's SPPP guidance document
that is on our website -- there is a section on delineating outfalls and drainage
areas. The link is here: http://h2o.enr.state.nc.us/su/Manuals Factsheets.htm
Find the stormwater Pollution Prevention Plan Guidance Document(middleof the
table), and go to pgs 3-4.
If you have other questions or comments, please let me know.
Regards,.

Dear Bethany,
I have received the draft permit for Unitex Chemical Corporation NCS000107. After
review I have the following questions:
1. What test methods (EPA?) should be used to determine COD, o-Xylene, and pH?
2. Do the above tests have to be done by a certified lab or can my laboratory do
the analysis (my laboratory is not certified by NCDENR).
3. How do I procure reporting forms? Section E 1 indicates these forms are
provided by the Director but no specifics are included.
4. What is the recommended procedure to determine drainage area for each outfall

Impairments and Basinwide Recommendations: This site is in a watershed with multiple urban influences .
(along a very populated corridor of 1-85), and South Buffalo Creek suffers from several impacts of this
urbanization. The stream is filled with debris, and the banks are eroded. This creek has had problems with
fluoride, cyanide, selenium (TMDL developed for these pollutants), as well as turbidity (2006 Impaired Waters
[303(d)] List), and it remains on the current draft 303(d) List for impaired biological integrity. There was no
information readily available about the TMDL approved for this creek in 1997; however, this facility should not
be a point source of fluoride, cyanide, or selenium.
The Metro (T.Z. Osborne) WWTP (NC0047384) discharges further d6wnstream of Unitex Chemical and has
had significant cyanide permit limit violations in the past. The Unitex facility is also inside Greensboro, whose
MS4 was permitted as part of the Phase I stormwater regulations.
The Cape Fear Basinwide Plan recommends that the city of Greensboro continue to monitor water quality in
South Buffalo Creek, and that DWQ continue to work with the City to identify measures for reducing
stormwater impacts to the creek. The facility does not discharge to Greensboro's MS4, but Greensboro's efforts
could still affect the site.
4. Threatened and Endangered: None identified in NC Natural Heritage Program Virtual Workroom GIS database
(Queried 4/2/2008).
Page 3 of 8

NCS000107
5. Location: Facility is within Greensboro, near I-40 and US-29, northwest of South Buffalo Creek.
6. Industrial Changes Since Previous Permit: During the previous permit term, there have been installations of new
buildings, a new line inside the process plant, and new process components (e.g., distilIation column).
Wastewater piping and equipment have also been modified. Notable industrial process change: liquid phthalate
plasticizer manufacture has ceased at this plant. See discussions with permittee about current industrial
activities.
Chemicals Stored: Company submitted list of chemicals stored (see excerpt from Accidental Discharge Plan,
attached). A variety of organics (including alcohols and solvents), sulfonamides, caustics, fuel oil, etc. are listed.
All tank areas diked and alarmed, and only one loading area is uncovered (which drains to sump with ability to
pump to POTW). These areas do not appear to pose a large concern for stormwater contamination given the
facility's storage practices and ability to contairddivert spills. Chemical Oxygen Demand (COD) and pH are
appropriate indicators for problems during this permit term. Future reviewers may consider removing at the next
renewal if values are consistently below benchmarks, unless these parameters are deemed useful for continued
vigilance.
Analytical Monitoring Notes: There was quarterly monitoring of total nitrogen required in the fourth year of the
permit only. Company monitored/reported TKN instead (nitrates/nitrite concentrations not included) for four
sampling periods. TKN concentrations were well below benchmark of 20 mgll, but no reason to expect high
levels of nitrate/nitrite concentrations. See Table 1. The last sample was just outside the final quarter dates.
Continued nitrogen (TN) monitoring is not recommended. There is no phosphorus data to date, but also no
apparent sources —no TP monitoring recommended.
9. Qualitative Monitoring Notes: No problems noted.

Revised Permit Recommendations: Analytical Monitoring:
I . Chemical Oxygen Demand (COD benchmark 120 mg/I), o-Xylene (benchmark 4.03 mg/i), and pH (within 6-
9, standard when any monitoring required) have been added to the analytical monitoring requirements. COD is
a good general surrogate for identifying contamination from the types of materials stored here —particularly at a
business where specialty organic chemical products change periodically depending on market demand. Xylene
is a prominent chemical stored, used, and reported in the TRI (o-xylene is the specified isomer, boiling point
I44.50 C) and is not as volatile as the alcohols stored on site. However, sufficient data below the benchmark
would justify removing xylene monitoring during the next permit term. COD and pH may continue to be useful
indicators in future permit terms or may not be necessary.
2. Total Suspended Solids (TSS) and Total Recoverable Zinc are proposed in the EPA draft 2006 Multi -Sector
Permit for this industry category (which is very broad). However, the reviewer does not see a basis to introduce
those parameters in the renewal permit at this time. There are no noted solids problems and no sources of zinc in
the materials used here.
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 response guidelines in the permit.
5. The permittee is required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part II Section B. Qualitative monitoring is required regardless of representative
outfall status.
6. Permittee responsible for all monitoring until the renewal permit is issued (see Footnotes of Tables 1, 4, and 5).
7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall and event
duration parameters are in this permit, however.)
8. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Other Proposed Changes to the Previous Permit:
1. Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants in each
outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of significant
spills that have occurred in the past three years and also must certify that the outfalls have been inspected to
ensure that they do not contain non-stormwater discharges. Additional information is provided in Part II Section
A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part 11 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.

Discussions with permittee: Dr. Jim Day, [phone], April 3, 2008:
1. Q: Facility ceased making phthalates some time ago. What does this site manufacture now?
a. ANSWER: Mostly additives for plastics. There are three main categories of products: (1) flame
retardants for plastics (e.g., wiring), (2) plasticizers for nylon (e.g., sulfonamide -based chemicals that
make nylon more flexible for use in fuel hoses, for example), and (3) orefins used in paper and
cosmetics.
2. Q: What is stored and loaded/unloaded outside?
a. ANSWER: All tank farms are diked and alarmed; major raw materials stored are things like ethyl
hexanol, xylene, and finished products. Will send flow plan submitted to City as part of S1U
requirement that will show all materials stored [attached].
3. Q: Is there a list of chemicals stored on site?
a. ANSWER: Yes, the company maintains this information for its SIU (Significant Industrial User) permit
with the City. Will send a copy [excerpt attached].

Spill and Leak Prevention Equipment and Procedures
At Unitex, all loading/unloading areas are covered, with the exception of the Tank�vagon
unloading area behind the LP-2 Production area. The area behind LP-2 is used for
different operations. Loading products straight from reactors to a tanker. This area is also
used to unloading molten materials that solidify quickly upon cooling and present
minimal danger to sewer/storm water contamination. In addition, the area has sloped
drainage to sumps, which empty into the wastewater collection tank for ultimate
discharge to the Publicly Owned Treatment Works (POTW). All manufacturing areas are
covered to prevent exposure to sewer/storm water.
All outside storage tanks are diked with connections only for recovery of material in the
event of a spill or for discharge to the POTW. No discharges from the diked areas shall
be released to the storm water drainage system.
The manufacturing areas (UP-], UP-2, LP-1, LP-2), flammable storage warehouse, drum
storage heated warehouse, centrifuge building, and pilot plant are designed to contain
accidental spills or leaks and prevent their run off to the outside. All of these areas have
controlled drainage systems and must be manually pump by personnel.
Raw material and finished products at Unitex are stored in enclosed warehouses or other
covered plant areas, or in bulk storage tanks. All bulk storage tanks are contained in
concrete diked areas that have no direct outlets to the sewer system/storm sewer. Bulk
materials are unloaded/loaded into/from tank trucks under a covered loading station
through stainless steel transfer lines to designated storage tanks or directly into the
manufacturing equipment. Drummed, bagged, or other non -bulk materials are
load/unloaded at shipping/receiving docks and are not exposed to storm water/sewer.
Prevention of contaminants into the sewer/storm water system at Unitex will be
accomplished by inspection of all operating equipment, storage areas; storage tanks, and
loading/ unloading areas for leaking lines, valves. and associated equipment. This shall
be done in conjunction with the monthly inspections conducted by the Maintenance
Department and documented on the inspection reports. Also, each shift supervisor has a
walk through the plant a minimum of twice during their shift looking at the equipment in
all areas of the plant. The plants personal are constantly walking through the plant while
doing their job and are instructed to report anything that looks out of the ordinary. The
Unitex facility is inspected by an outside security service and by
supervisory/administrative personnel during weekends, holidays, and other shutdown
periods for general conditions of the facility, including spills and leaks.
Another way the Unitex tries to reduce accidental spills is the use of transfer sheets. "Che
operator to ensure that material transferred to/from the bulk storage tanks will
accommodate the amount being transferred to the tank/reactor uses a transfer sheet. This
sheet must be reviewed and signed off by the shift supervisor and the operator that is
making the transfer.

Daily washing down the production areas. so that spilled materials will not be "tracked"
outdoors for potential seNver/storm water contamination.
All spills within the facility, including driveways, loading/unloading areas, and diked
areas shall be immediately cleaned up for proper disposition, as directed by the Plant
Manager. Absorbent materials are maintained on -site for use in cleaning up spills (e.g.,
"floor" absorbent, pigs).
Emergency Response Equipment and Procedures
Emergency Equipment
There are multiple radios located with key personal through out the plant during all
operation hours. The plant manager and the environmental manager also have beepers in
order to be contacted after hours.
All tank farms are contained inside concrete dikes and the pumps inside the tank farms
pump to a central controlled tank (U). All tanks have level alarms that sound inside and
outside the plant at 70% and 80% capacity.
All drains inside the operation areas drain to a central controlled location. If material is
spilled inside the warehouses and the production areas, there are floor drains and sloped
floors to keep the material inside the building. There is floor dry absorbent material
located in Flammable storage warehouse, S-1; S-3, and P-3/Centrifuge building in order
to absorb spills and to prevent material from entering unwanted areas. There are also
PIGS in S-1 to contain small spills.
All plant personnel are trained in the use of protective equipment and are issued a
respirator. -These respirators are located in the employees' lockers. Certain personnel are
trained in the use of SCBA type respirator. These respirators are located in S-2 and the
Stripper shack near gate 1.
The plant is equipped with ventilation fans through out the facility: These ventilation
fans are usually running during normal plant operations.
There are two first aid kits available to plant personnel during operational hours. One is
in S-2 near the Quality Coordinators' Office and the other is in the maintenance shop
near tank farm E.
This facility is protected by a sprinkler fire protection system. These systems shall be
maintained and tested in accordance with OSHA regulations and local codes by ADT.
Fifty-four fire extinguishers and five standpipe hoses are located in the following areas:
S 1, S2; S3, 1`3(grinding side); and flame shed, which locations are -in accordance with the
Greensboro Fire Department regulations. There also two water cannon located near the
tank farm. One is located beside tank farm B. And the other is located between tank
farms D and C near gate ##5. These items are inspected and maintained by outside
subcontractors in accordance with applicable regulations.

Procedures:
Raw material and finished products at Unitex are stored in enclosed warehouses or other
covered plant areas, as well as in bulk storage tanks. All bulk storage tanks are contained
in concrete diked areas that have no direct outlets to the stonn sewer/ sewer. Bulk
materials are unloadcd/loaded into/from tank trucks under a covered loading station
through stainless steel transfer lines to designated storage tanks or directly into the
manufacturing equipment with the exception of the aforementioned area behind LP-2.
These areas has sloped drainage to sumps, which empty into the wastewater collection
tank for ultimate discharge to the Publicly Owned Treatment Works (POTW).
Drummed, bagged, or other non -bulk materials are load/unloaded at shipping/receiving
docks and are not exposed to storm sewerslseNvers.
Any person in the Unitex Facility, upon discovery of a spill shall immediately inform his
shift supervisor or the Plant Manager. The Plant Manager or his designate is responsible
for spills assessment and will coordinate the clean-up efforts. Actions to prevent run-off
of the spill shall be initiated promptly. In case of a small spill, absorbent material (stored
in the flammable storage warehouse, product storage area S-2, product storage area S-3,
and P-3/Centrifuge area) will be placed on the spill and shoveled into drums for disposal
at a licensed waste disposal facility for hazardous material. Nonhazardous waste is
disposed of to permitted secure landfills, permitted Waste Disposal Facilities, or through
BFI; dumpsters are on -site for such collection for disposal through BFI. Nonhazardous
waste that is acceptable to the sanitary landfill is shipped to the Greensboro landfill. In
case of a large spill, the material will be contained within the plant area, pumped into a
licensed hazardous waste tanker and hauled to a licensed waste disposal site. A spill of
non -hazardous material shall be evaluated, with the assistance and concurrence of the
POTW, for discharge to the POTW. If this is not allowed, the contaminated water shall
be pumped into one or more of the diked areas for disposal, as determined appropriate by
environmental management, plant management and corporate management, and in
accordance with all local, state, and federal regulations. Only those personnel who have
received training to first responder level shall be allowed to remediate, or otherwise
handle, hazardous materials resulting from an incident.
if evacuation is needed, the fire alarm will be pulled to indicate an evacuation is
necessary. All employees hearing the alarm will immediately initiate emergency
shutdown of process equipment and proceed by the nearest safe exit to the easterly
parking lot entrance (Gate Number 1) on Broome Road (atmospheric conditions
permitting, see wind direction by observing wind sock on SR-1720 Alcohol Distillation
Column). The Emergency Coordinator will immediately conduct a roll call to determine
if all Unitex personnel, contractor employees, and visitors are accounted for. An
employee roster is located in the "MSDS" orange storage box at Gate 1. if possible,
visitor logs shall be retrieved from the facility for verification that all on -site personnel
are accounted for. All persons will remain at Gate Number I for further instructions
from the Emergency Coordinator or the Emergency Management Representative.

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table I- 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
and that is preceded by at least 72 hours in which no storm event measuring greater than 0.1
inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation. For example, if it rains for 2 hours without producing any collectable discharge,
and then stops, a sample may be collected if a rain producing a discharge begins again within the
next 10 hours.e

address biological integrity and/or the stressors contributingao-the impairment, the permittee may
qk
be required to'monitor for one or more pollutant(s)C%£concern in the future and submit results to
the Division of eater Quality. The Division will�consyder 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- tii"e;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 BMfflPs into the�"permitted Stormwater Pollution Prevention Plan.

Subject: Draft NPDES Stormwater Permit
Permit No. NCS000107
Unitex Chemical Corporation
Guilford County
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Several of these changes reflect
the Division's revised strategy for all stormwater renewal permits. 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:
• Total Nitrogen (TN) monitoring has been removed from Part I1, Sec. B.
• Chemical Oxygen Demand (COD), o-Xylene, and pH monitoring have been added Part 11, Sec. B, based
on the types of materials stored at this facility.
All analytical monitoring has been set to semi-annually during a representative storm event as defined
in Part 11, Sec. B. -If no discharge occurs during the sampling period, you 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. This schedule also applies to
monitoring triggered by vehicle maintenance activities. This change reflects the Division's revised
strategy for renewal permits and makes stormwater sampling frequency consistent with qualitative
monitoring.
The Division has incorporated benchmark values into the permit. These benchmarks are not permit
limits. However, exceedences 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 tiered responses
outlined in the permit.
• Total Flow monitoring has been removed. The permit still requires Total Rainfall amount be recorded
for each sampling event. This change is also based on the Division's revised strategy for stormwater
monitoring in renewal permits. Please note that the Stormwater Pollution Prevention Plan (SPPP) site
map must include drainage area for each outfall in acres and the percentage of each drainage area that
is impervious (see Part II, Sec. A).
• Qualitative monitoring must now be performed during the analytical monitoring event (i.e., during a
Carolina
representative storm event). N

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
and that is preceded by at least 72 hours in which no storm event measuring greater than 0.1
inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation. For example, if it rains for 2 hours without producing any collectable discharge,
and then stops, a sample may be collected if a rain producindischarge begins again within the
next 10 hours.

SECTION C: QUALITATIVE MONITORING REQUIREMENTS
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status and shall be performed as specified in Table 4, and during the
analytical monitoring event. Qualitative monitoring is for the purpose of evaluating the
effectiveness of the Stormwater Pollution Prevention Plan (SPPP) and assessing new sources of
stormwater pollution.
In the event an atypical condition is noted at a stormwater discharge outfall, the permittee shall
document the suspected cause of the condition and any actions taken in response to the
discovery. This documentation will be maintained with the SPPP.

Total Flow
The flow corresponding to the time period over which the entire storm event occurs. Total flow shall be
either; (a) measured continuously, (b) calculated based on the amount of area draining to the outfall, the
amount of built -upon (impervious) area, and the total amount of rainfall, or (c) estimated by the
measurement of flow at 20 minute intervals during the rainfall event.
Total Maximum Daily Load (TMDL)
A TMDL is a calculation of the maximum amount of a pollutant that a waterbody can receive and still meet
water quality standards, and an allocation of that amount to the pollutant's sources. A TMDL is a detailed
water quality assessment that provides the scientific foundation for an implementation plan. The
implementation plan outlines the steps necessary to reduce pollutant loads in a certain body of water to
restore and maintain water quality standards in all seasons. ThetClean Water Act, section 303, establishes
the water quality standards and TMDL programs.

Subject: NPDES Stormwater Permit Renewal
Unitex Chemical Corporation
Permit Number NCS000107
Guilford County
Dear Permittee:
Your facility is currently covered for stormwater discharge under NPDES Permit NCSOOOt07. This permit expires
on October 31, 2004. North Carolina Administrative Code (15A NCAC 2H.W05(e)) requires that an application
for permit renewal be filed at least 180 days prior to expiration of the current permit. In order to assure your
continued coverage under your permit, you must apply to the Division of Water Quality (DWQ) for renewal of
your permit. To make this renewal process easier, we are informing you in advance that your permit will be
expiring. Enclosed you will find an individual permit renewal application form, supplemental information request,
and Stormwater Pollution Prevention Plan certification.
Filing the application form along with the requested supplimental information will constitute your application for
renewal of your permit. 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 143-215A 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 Stormwater and
General Permits Unit at [phone], ext. 548.

Best Management Practices
1. Stormwater Management Plan
At Unitex, all loading and unloading areas are covered with exception
of Tankwagon unloading behind LP-2 production areas (this area is
rarely utilized). All production areas and tank farm pads/dikes are
collected in a tank for discharge to the local PQTW. These areas are
designed for spill containment of accidental spills/leaks and to prevent
run off outside. No discharges are allowed to the stormwater runoff
outfall.
Empty containers stored outside shall be triple rinsed. All chemicals
will be stored in areas with secondary containment. All containers will
be sealed in storage. All containment areas will have discharge valves
closed at all times.
2. Spill Prevention and Response Plan
The Spill Prevention and Response Plan is in place as part of the
Emergency Contingency Plan for the facility. This plan is reviewed and
drilled on an annual cycle. The facility is inspected by an outside
contract security service and by supervisory personnel during periods
when the facility is not in operation (e.g. weekends, holidays, and
other shutdown periods).
3. Preventive Maintenance and Good Housekeeping Program
Routine and preventive maintenance is performed under the
supervision of the Maintenance Supervisor and the Plant Manager.
This activity includes daily, weekly and monthly inspections of various
pieces of equipment in the facility. Each shift supervisor inspects the
entire facility every 12 hours for leaks, spills, repairs and for areas
requiring housekeeping.
4. Employee Training
The Spill Prevention and Response Plan is part of the facility
Emergency Contingency Plan with a focus topic on the Stormwater
Pollution Prevention Plan. All operations/lab/supervisory personnel
receive annual training. All new employees receive training prior to
being released for duty.
2

5. Facility Inspections and Recordkeeping
Facility inspections are conducted and records are maintained.
Documentation of the inspections and corrective actions as necessary
is maintained with this plan.
6. Sediment and Erosion Control
No areas in the facility have a high potential for significant soil erosion.
Equipment is available on -site to aid in sediment and erosion control.
Grass or stone are located in areas which as impervious.
7. Management of Run-off
The primary source of stormwater run-off is the run-off from I-85/I-40
at the perimeter of the facility. A run-off drain dumps to the
containment pad behind LP-2, which discharges to the industrial
wastewater tank (and the POTW).
Significant Changes to Facility
Over the last five years there have been some significant changes to
the plant facility. These changes include:
- Construction, installation and start-up of a self-contained drying and
micronizing building.
- Installation and start-up of a self-contained drumming line with feed
tank inside the process plant.
- Installation of a self-contained alcohol recovery distillation column.
• Installation of an additional centrifuge in the centrifuge operations
building.
- Modification of wastewater piping and equipment to improve
efficiency and operability.
All manufacture of liquid phthalate plasticizers have ceased. New
product development has focused on the development and
manufacture of environmentally friendly processes and products.
No significant spills have occurred inside or outside the process plant
or the facility perimeter over the last 5 years.

'You must monitor quarterly in the first year of your coverage for each benchmark parameter (see Part 3.2.2.1). For
each parameter, no additional benchmark monitoring is required if the average of your 4 monitoring values does not
exceed the benchmark (see Part 3.2.2.3). However, for each parameter there are additional requirements if the
average of your four monitoring values exceeds the benchmark (see Part 3.2.2.4).
2Monitor once per year for each monitoring year.
' The benchmark value of lead is determined as a function of hardness (in units of mg/L) in the water column. The
value given in Table C-1 (i.e. 0.082 mg/L) corresponds to a hardness of 100 mg/L and should be used if you either
did not analyze water hardness, other hardness data are not available, or the water hardness is less than 100 mg/L. If
a laboratory analysis indicates that the water hardness is below 100 mg/L, then you should use the benchmark for
100 mg/L. If a laboratory analysis indicates that the water hardness is greater than 100 mg/L, then the following
equation may be used to determine the benchmark value for lead:
Benchmark = (e I0.273)(ln hardness) — 1.4601)/1000
Example: Laboratory analysis of your water sample indicates the hardness is I75 mg/L.
Benchmark = (e [(1.273)(1n 175) — 1.460] )/1000
_ (e5.1148)/1000
= 166.46/1000

a laboratory analysis indicates that the water hardness is below 100 mg/L, then you should use the benchmark for
100 mg/L. If a laboratory analysis indicates that the water hardness is greater than 100 mg/L, then the following
equation may be used to determine the benchmark value for zinc:
Benchmark — (e [(0.8473)(In hardness) + 0.8841 )/1000
Erample: Laboratory analysis of your water sample indicates the hardness is 175 mg/L.
Benchmark = (e [(0.8473)(in 175) + 0.884])/ 1000

If the CWA permit is past its expiration date, this normally means that the permitting authority has not yet issued a new permit. In
these situations, the expired permit is normally administratively extended and kept in effect until the new permit is issued.
For the RCRA program, activities that contribute to an overall facility status of Active are displayed in parentheses using the
acronym HPACS, where H indicates handler activities, P - permitting, A - corrective action, C - converter, and S - state -specific.

From: Aisha Lau
Subject: Review of NCS000107 Stormwater Permit Renewal
Unitex Chemical Corporation performed all of their qualitative monitoring as they were
directed in their permit. Previously they had no analytical monitoring requirements, but
since they are in NSW waters in the Cape Fear River Basin and recently added a bulk
liquid nitrogen tank, and their nitrogen numbers were borderline when their application
was initially submitted Total Nitrogen has been added as a parameter to monitor. None
of their processes use phosphorous, so it was not added. They will only be required to
monitor the last year of their permit because they complied well with their existing
permit.

SITE PLAN
Attached is a site plan showing the Unitex Facility in relation to transportation routes, surface
waters, and receiving water (South Buffalo Creek) of the Stormwater outfalls.
Raw material and finished products at Unitex are stored in enclosed warehouses or other
covered plant areas, as well as in bulk storage tanks. All bulk storage tanks are contained in
concrete diked areas that have no direct outlets to the storm sewer. Bulk materials are
unloaded/loaded intolfrom tank trucks under a covered loading station through stainless steel
transfer lines to designated storage tanks or directly into the manufacturing equipment.
Drummed, bagged, or other nonbulk materials are load/unloaded at shipping/receiving docks
and are not exposed to Stormwater.
Hazardous waste at Unitex is shipped off -site to Permitted Disposal Facilities via Permitted
Transportation. Nonhazardous waste is disposed of to permitted secure landfills, permitted
Waste Disposal Facilities, or through BFI; dumpsters are on -site for such collection for disposal
through BF1. Nonhazardous waste that is acceptable to the sanitary landfill is shipped to the
Greensboro landfill.

SITE MAP
Attached is a site map of the Unitex Chemical Facility showing the following:
1. Industrial activities
2. Drainage areas for each outfall
3. Activities occurring in the drainage area
4. Building locations
5. Impervious areas
Approximately 58 percent of the drainage area associated with industrial activity is impervious.
There are two outfalls as shown on the site map. The potential pollutants at each outfall are
essentially identical. The potential pollutants include:
1. Raw materials used in manufacturing include various alcohols, organic acids and
anhydrides, sulfonyl chlorides, inorganic alkaline materials, and organic solvents.
2. Finished products, including esters, sulfonamides, polymers, and other specialty organic
compounds.
During the past three years, there have been no significant spills or leaks of ,pollutants that
have come into contact with Stormwater discharges.

STORMWATER MANAGEMENT PLAN
At Unitex, all loading/unloading areas are covered, with the exception of the Tankwagon
unloading area behind the LP-2 Production area. The area behind LP-2 is used primarily for
unloading molten materials which solidify quickly upon cooling and present minimal danger to
stormwater contamination. In addition, the area has sloped drainage to sumps, which empty
into the waste water collection tank for ultimate discharge to the Publicly Owned Treatment
Works (POTW). All manufacturing areas are covered to prevent exposure to stormwater.
Any empty containers stored outside shall be triple rinsed and any bungs, caps, or other
closures shall be in place prior to being moved outside.
All outside storage tanks are diked with connections only for recovery of material in the event
of a spill or for discharge to the POTW. No discharges from the diked areas shall be released
to the stormwater drainage system.
The manufacturing areas (UP-1, UP-2, LP-1, LP-2), flammable storage warehouse, drum
storage heated warehouse, centrifuge building, and pilot plant are designed to contain
accidental spills or leaks and prevent their run off to the outside.
Issue Date: 5121/98
Supersedes: 2/1/95
Page 5 of 13

SPILL PREVENTION AND RESPONSE PLAN
Potential pollutant sources at Unitex include:
Failed or broken valves, transfer lines, or hoses during loading/unloading operations.
2. Accidental release of material from reactors, if a rupture disc or pressure release valve is
activated, or in the event of broken valves or lines.
3. Accidental spills while transporting containers between the production/warehouse areas
and the flammable storage or hot room buildings.
4. Water from fire fighting/damage control operations in the event of a fire or other
unplanned event requiring large amounts of water release.
Any person in the Unitex Facility, upon discovery of an actual or threatened release to the
stormwater, shall immediately inform his shift supervisor or the Plant Manager. If unable to
contact these persons, the person shall dial 911 and describe the problem to the fullest extent
possible. Actions to prevent run-off of the contaminated stormwater shall be initiated promptly.
A back hoe/front-end loader located at the facility is available to create earthen dams to help
prevent contaminated stormwater from entering the stormwater discharge points. Such
retained stormwater shall be evaluated, with the assistance and concurrence of the POTW, for
discharge to the POTW. If this is not allowed, the contaminated water shall be pumped into
one or more of the diked areas for disposal, as determined appropriate by environmental
management, plant management and corporate management, and in accordance with all local,
state, and federal regulations.
The Unitex facility is inspected by an outside security service and by supervisory/administrative
personnel during weekends, holidays, and other shutdown periods for general conditions of
the facility, including spills and leaks that may pollute storm water discharges.

PREVENTATIVE MAINTENANCE AND GOOD HOUSEKEEPING PROGRAM
Prevention of contaminants into the stormwater system at Unitex will be accomplished by:
1. Inspection of all operating equipment, storage areas, storage tanks, and loading/
unloading areas for leaking lines, valves, and associated equipment. This shall be done
in conjunction with the monthly inspections conducted by the Maintenance Department
and documented on the inspection reports.
2. Daily washing down the production areas, so that spilled materials will not be "tracked"
outdoors for potential stormwater contamination.
All spills within the facility, including driveways, loading/unloading areas, and diked areas shall
be immediately cleaned up for proper disposition, as directed by the Plant Manager.
Absorbent materials are maintained on -site for use in cleaning up spills (e.g., "floor" absorbent,
pigs).

EMPLOYEE TRAINING
All employees in the Manufacturing, Shipping, Receiving, and Maintenance Departments will
be trained at least annually on proper response, clean-up procedures, and preventative
maintenance on events that have the potential to contaminate stormwater run-off. This
training shall be conducted in conjunction with the Monthly Safety and Emergency Response
Training Meetings by the Plant Manager, Safety Officer, or Environmental Manager. Such
training shall be documented in the Safety Meeting Minutes, and the names of all personnel
receiving the training shall be included, and initialed, by the recipients. A copy of the minutes
shall be kept in the Employee Training Manual (or file), along with this Plan. Such training also

SIGNIFICANT CHANGES TO FACILITY AT
UNITEX CHEMICAL CORPORATION
Over the last five years there have been some significant changes to the plant
facility. These physical changes include:
. Installation of a Bulk Liquid Nitrogen Storage Tank
+ Installation of a self-contained Centrifuge Building with equipment for
the isolation of solid products.
• Installation of a concreted, diked tank farm with storage tanks.
• Removal of all underground storage tanks with closure from the state.
• Complete renovation of the process plant equipment to improve
efficiency and operability.
A number of chemical processes have been discontinued in order to limit risks to
the environment, namely most Phthalate esters (e.g. Dimethyl phthalate, Diethyl
phthalate). New product development has focused on the creation, development
and production of "environmentally -friendly" processes and products.
No significant spills have occurred inside or outside in the process plant or the
facility perimeter over the last 5 years.
