Glen,
I have another Chemol update. At sometime during the night of December 311, a valve on one of their ASTs froze and
busted. There was enough pressure to spew the oil/grease product out of the break in the valve. The estimate was that
about 100 gallons made it outside of the secondary containment. Their security guard found the spill in the morning
and notified William Newlin. Some product did make it to the curbline of the street, but it was cold enough to freeze
and stop it from flowing any further. William notified the proper authorities and cleanup began once Shamrock arrived
that afternoon. They finished the cleanup on January 2"d
I've attached some photos of the spill.

Hi Glen,
It was nice meeting you the other day at the Chemol site visit. I hope we didn't overwhelm you with all the fun that is
permit renewal!
I don't know what your process is for following up on facility inspections, but in case you can use them, here are the notes
I took down on Chemol. Mike, Rick, or Sue — please feel free to add to this.
• They would be interested in being covered under general permit NCG06 rather than an individual permit, if that's
appropriate. Their SIC code 2869 is not specified in the NCG06, but we can discuss whether their operation is
similar enough to be covered under NCG06. I think you may be able to search in BIMS for other facilities with that
SIC code and see what permits they have.
• They have at least two outfalls on their site but have been sampling only one outfall (001) based on approval from
Oct 1993 letter which may have only been applicable during application process. The problem with sampling only
Outfall 001 is that it only receives stormwater from employee parking and roof, and not from the industrial
areas. Outfall 002 is inaccessible, however, and there didn't appear to be an alternative sampling location
upland. Suggest documenting these findings in a new letter granting ROS with added housekeeping measures on
the back side of the property that would include having a spill kit, cleaning grease/oils from metal stairs and other
areas, modifying tank filling procedures so grease doesn't spill down sides, etc.
• No data during some of the sampling periods. They should get sample kits so facility staff can collect samples
after rainfall events.
• pH was outside benchmark range in at least one sample. This could be because the collected sample is not being
tested for pH in a timely manner. The sample should be analyzed within 15 minutes of collection (see attached
guidelines).
• They need to document that they're doing annual spill response reviews.
Thanks again for helping with the individual permit renewals. Feel free to call or email any time with questions. Bethany
is a great resource as well.

I remember this facility and it was poorly maintained. I don't know if they are even monitoring at the outfall at the rear
of the plant where there is significant exposure from their industrial processes. The samples they were collecting were
coming from their outfall at the street. It only captured a small portion of the drive and roof and part of the street.
I don't know why Chemol started testing the pH of their rainfall nor why they collect that sample at a different time from
the monitoring sample. As you said, other facilities in their vicinity haven't had issues with pH. Don't know why they are
getting those results. Maybe they aren't testing within the first 30 minutes of collection.
I agree with you and I think pH should stay in their permit as is, if it triggers a tiered response, they need to investigate
the issue causing acidity. The issue can be revisited if they can prove their case is valid.

Glen,
What's your take on their request for relief from pH monitoring? Also, do you know what prompted them to start
testing the pH of their rainfall? It's curious to me that the pH of their stormwater pre-2013 was in the normal range, but
since then, they've started getting some lower values. I'm stumped as to what would cause this shift. Any ideas?
I'm inclined to keep pH as a parameter in their renewed permit for a few reasons:
1. I'm not certain they've taken any steps to evaluate possible causes of low pH in their stormwater samples from
their site;
2. After talking to Div of Air Quality, it doesn't sound likely that there's a localized acid rain problem, and their
recent inspection indicates the site is still poorly maintained;
3. Chemol's neighbors —Valley Protein and Evonik — don't seem to be having pH issues at their facilities; and
4. Their rainfall testing wasn't done on the same days as their stormwater sampling — it would be more useful to
have data collected on the same day;
If we keep pH in their permit as is, they are likely going to trigger the tiered responses. Maybe we could suggest they
continue to monitor the pH of their rainfall (simultaneously with their stormwater sampling), so if they do trigger the
tiers, we could reconsider relief from the tiers if/when they've exhausted all other options to address the issue? The

way this would work is we could consider issuing a letter allowing them to use the lower of the measured
rainfall/stormwater pH as the minimum benchmark level.
Thoughts?

Mr. Newlin,
Our typical procedure for considering requests for relief from a monitoring requirement includes evaluating whether the
permittee has taken all steps required by the permit to evaluate their site conditions and address potential pollutants
from their processes.
• Would you please send me the data you have for the rainfall as well as the results from your outfalls since
February 2017 (or whatever data you have that is the most recent)? Attached. Note on small rainfall totals pH
paper was used since the gauge volume was not sufficient for a pH meter. All samples were checked with pH
paper. Note I have edited the rainfall sampling log to include all times for the future.
I'd also like to know where the rain gauge is located that you used to collect the rainfall. is it near your offices,
or closer to the industrial processes? The gauge is located between the plant and the office. Approximately 40
feet from office building and @80 feet from the plant.
Lastly, can you tell me if you've been following the attached pH testing guidelines? Most importantly, the pH
should be measured within 15 minutes of collecting the sample. Otherwise, you could be getting lower pH
levels because of the delay in measuring the pH.

:p
1. The pH was measured during the rain event on 2 of the 4 attached sheets. The last one from 5/23/17 was
tested after 1.5 inches of rain and it continued to rain another .2 inches after the sampling.
2. The pH meter is calibrated on a daily basis and the probe is stored in a pH buffer.
3. -The buffer solution is traceable.
0 Can you briefly summarize what steps you have taken to determine whether any parts of your industrial process
could be contributing to low pH, such as from leaks/spill from acid tanks, air emissions, etc.
We have looked at the sample and verified it is clear and free form any visible contaminates.
Our primary materials are triglycerides and their derivatives. Contamination by fats or fatty acids would be visible.
We burn natural gas in our boilers so that should not affect the pH of the rain.
I am including prior pH results from storm water sampling performed by Operations Excellence. Note the samples
were analyzed by R&A Labs in Kernersville, NC, but I cannot verify the pH procedures followed.

Ms. Ventaloro,

r
Chemol is in receipt of the draft Storm water permit for Chemol Company Inc. I wanted to touch base and let
you know that we have been testing the pH of the rainfall at Chemol Company Inc. located at 2300 Randolph Ave.,
Greensboro, NC 27406 since February 2017. The pH of the rainfall consistently test in the 4.0 to 4.5 pH range. Due to
this Chemol will need a variance on the pH benchmark.
We are in the process of establishing a sampling point for Outfall #2. 1 say this to let you know it may require
some grading and construction.
Please confirm what is required to be allowed a pH variance?

Ms. Ventaloro,
Chemol is in receipt of the draft Storm water permit for Chemol Company Inc. I wanted to touch base and let
you know that we have been testing the pH of the rainfall at Chemol Company Inc. located at 2300 Randolph Ave.,
Greensboro, NC 27406 since February 2017. The pH of the rainfall consistently test in the 4.0 to 4.5 pH range. Due to
this Chemol will need a variance on the pH benchmark.
We are in the process of establishing a sampling point for Outfall #2. 1 say this to let you know it may require
some grading and construction.
Please confirm what is required to be allowed a pH variance?

TECHNICAL ASSISTANCE FOR FIELD ANALYSIS OF pH
This document is intended to provide technical assistance and guidance for the measurement of pH. This is not meant to be a
substitute for the method, but is offered as a guide to the method.
HOLDING TIME:
• Samples must be analyzed within 15 minutes of collection.
METER CALIBRATION:
The meter must be calibrated prior to the analysis of samples.
If compliance samples are analyzed throughout the day, a post calibration check (e.g., 7 buffer) must be analyzed mid-
day and at the end of the run (i.e., roughly every 4 hours based on an eight hour day).
For routine work, use a pH meter accurate and reproducible to 0.1 pH unit with a range of 0 to 14, equipped with a
temperature compensation device. Follow all manufacturers' recommendations for the calibration of the meter each
analysis day. In all cases, the meter must be calibrated with at least two buffers. Calibrating with the pH 4 and pH 10
buffers meets standard methods requirements and brackets the pH range for most monitoring (with the exception of
sludge) scenarios. The calibration; however, must bracket the range of the samples being analyzed. In addition to the
calibration standards, the meter must be verified with a third calibration standard (e.g., pH 7 buffer).
• In order to meet the above -specified criteria, the standard must read within a range of pH 6.9 to 7.1 to be acceptable.
General Information:
• Samples shall be gently stirred during measurement.
• The electrode must be rinsed and blotted dry between measurements.
All thermometers and temperature measuring devices must be checked every 12 months against a NIST certified or
NIST traceable thermometer and the process documented even if the instrument is not used for reporting temperature
results. To check a thermometer or the temperature sensor of a meter, read the temperature of the thermometerlmeter
against a NIST certified or NIST traceable thermometer and record the two temperatures. The thermometer/meter
readings must be less than or equal to 10C from the NIST certified or NIST traceable thermometer reading. The
documentation must include the serial number of the NIST certified thermometer or NIST traceable thermometer that was
used in the comparison. Also document any correction that applies on both the thermometer/meter and on a separate
sheet to be filed. (NOTE: Other certified laboratories may provide assistance in meeting this requirement.)
DOCUMENTATION:
The following must be documented whenever sample analysis is performed
1. Time and date of sample collection
2. Time of calibration
3. Time and date of analysis (to verify 15 minute holding time is met)
4. Collector's/analyst's name
5. Value of buffers used for calibration
6. Value obtained for check buffer (e.g., pH 7 buffer)
7. Sample location/site
8. Post calibration checks (if applicable)
9. Report all data values to the nearest 0.1 pH unit.
10. The temperature correction (even if it is zero) must be posted on
retained for 5 years).

Subject: Draft NPDES Stormwater Permit
Permit No. NCS000048
Chemol Company, Inc
Guilford County
Dear Mr. Newlin:
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. Tiered responses have been added to this 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 in accordance with Part I1, Section B of this permit.
3. Requirements for the Stormwater Pollution Plan (SPPP) have been updated in Part II,
Section A.
4. 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.
• The Total Phosphorus benchmark has been changed from 5 mg/L to 2 mg/L
for consistency with other industrial stormwater permits as well as wastewater
permit limits imposed on dischargers in Nutrient Sensitive Waters areas.

• 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.
5. A new section on Special Conditions has been added in Part lI, 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.
6. Civil and administrative penalty amounts have been updated to reflect current
federal law in Part III, Section A, 2(b) and (g).
This facility has not been granted Representative Outfall Status; as such, sampling must be
done at both stormwater discharge outfalls identified at this facility. Note that the facility's
current permit as well as this draft permit require cLuarterlx monitoring at all outfalls.
It is important to ensure that pH is tested onsite at the time of collection using a pH meter as
delaying this test could return pH levels that are not representative of the onsite conditions.
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
iulie.yentaloro(a,ncdenng_ov or mailed to my attention at NCDEQ, Land Quality Section,

PART 11 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 III, 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 SiteOvervi�I&I contain the following:
(a) A general location map (USGS quadrangle:inap orappropriately drafted equivalent
map), showing the facility's location in relation to transportation routes and surface
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 ultimate -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 state's 303(d) list of impaired
waters) or if the site is'locate&n 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 1S

Permit No. NCS000048
(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 econo"mic 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-flbw\Wherever practical, the
permittee shall prevent exposure of all storage areasmaterial 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 potential
c contamination.
//)V:
(b) Secondary Containment Requirements and Records. Secondary containment is
required for: bulk storage of lia/\ui materials; storage in any amour of Section 313
of Title III of the Superfun&Am`endin ents 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 mainta ned.Af'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 (5) 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 1I Page 2 of 15

Permit No. NCS000048
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, ancllhaul 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 or 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 established 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 II 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 I{ Page 3 of 15

Permit No. NCS000048
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 for
the presence of non-stormwater discha ges:(elemenk of the Site Overview);
(c) a documented re-evaluation of the effectiveness.ofthe on -site stormwater
BMPs (BMP Summary element of the-Stormwater Management Strategy).
(d) a review and comparison of sample analyticaHata to benchmark values (if
applicable) over the past year,, including.a,discussion about Tiered Response
status. The permittee shall use the Division's Annual Summary Data
Monitoring Report (DMR) formavail�able from the Stormwater Permitting
Program's website,(See"Monitori g Forms' here:
The Director may notify e 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 111, Standard Conditions, Section B, Paragraph 3) to the Director that the changes
have been made.
9. SPPP Implementation. The permittee shall implement the Stormwater Pollution
Prevention Plan and all appropriate BMPs consistent with the provisions of this permit,
in order to control contaminants entering surface waters via stormwater.
Implementation of the SPPP shall include documentation of all monitoring,
measurements, inspections, maintenance activities, and training provided to
employees, including the log of the sampling data and of actions taken to implement
BMPs associated with the industrial activities, including vehicle maintenance activities.
Such documentation shall be kept on -site for a period of five (5) years and made
available to the Director or the Director's authorized representative immediately upon
request.
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
Part II Page 4 of 15

Permit No. NCS000048
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.

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 30 days must separate each Monitoring
Period. Inability to sample because of adverse weather conditions must be documented in
the SPPP and recorded on the DMR. The permittee must report the results from each
Part II Page 5 of 15

Permit No. NCS000048
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 quarterly monitoring until either another permit is issued for this facility or until this
permit is revoked or rescinded. The permittee must 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 quarterly per 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
Part II Page 6 of 15

Permit No. NCS000048
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.

The benchmark values in Table 3 are not"Derr' it li/tnits but should be used as guidelines for
implementation of the permittee's SPPP.�An`exceedance of a stormwater benchmark value
is not a permit violation; however; failure to respond to the exceedance as outlined in this
permit is a violation of permit conditi1\
Tier One
If: The first valid sampling results`are above a benchmark value, or outside of the benchmark range, for any
parameter at any outfall;
Then: The permittee shall:
1. Conduct a stormwater management inspection of the facility within two weeks of receiving sampling
results.
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 the parameters of concern, and/or to bring concentrations
within the benchmark range.
4. Implement the selected feasible actions within two months of the inspection.
5. 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 separately trieaer 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 discharge outfall;
Part I1 Page 7 of 1S

Permit No. NCS000048
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.
5. Maintain a record of the Tier Two response in the SPPP.
b. Continue Tier Two response obligations throughout the permit renewal process.
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
analytical results;
Then: The Division may but is not limited to: • require that the permittee revise, increase, or decre�ase t� ��
he 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 implemenhsite modifications to qualify for a No Exposure Exclusion;
• require the permittee to continue Tier Three obligations through the Rermit renewal process.
This site discharges to waters which ultimately drain to Jordan Lake. Jordan Lake is
impaired and experiencing problems with Nitrogen, Phosphorus, pH, and Sediment. Under
the Total Maximum Daily Load (TMDL) approved for Jordan Lake, the permittee may be
required to monitor for other 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 needed to achieve the required level of control, the permittee will be
required to (1) develop a strategy for implementing appropriate BMPs, and (2) submit a
timetable for incorporation of those BMPs into the Stormwater Pollution Prevention Plan.
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
Part II Page 8 of 15

Permit No. NCS000048
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 quarterly 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).
In the event an atypical condition is noted at a stormwater discharge outfall, the permittee
shall document the suspected cause of the condition,and/an/y actions taken in response to
the discovery. This documentation will be maintained with the SEPP.

process until a new permit is issued.
2 Monitoring Location: Qualitative monitoring shall be performed at each stormwater discharge outfall
(SDO) regardless of representative outfall status.
A minimum of 60 days must separate monitoring slates, 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
Part II Page 9 of 15

Permit No. NCS000048
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.
ve momtorine xesvonse
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) e %��/�
• 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,modifica► to qualify for a No Exposure Exclusion.
SECTION D: ON -SITE VEHICLE -MAINTENANCE MONITORING REQUIREMENTS
Facilities that have any vehicle maintenance activity occurring on -site which uses more
than 55 gallons of new motor oiLper month when averaged over the calendar year
shall perform analytical monitoring as specified below in Table 5. 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,
and in accordance with the schedule presented in Table 2 (Section B).

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.
Z 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 be begun within
the first 30 minutes, and shall continue until completed.
3 Sample Location- Samples shall be collected at each stormwater discharge outfall (SDO) that discharges
stormwater runoff from area(s) where vehicle maintenance activities occur, unless representative outfall
status (ROS) has been granted. A copy of the 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 may
be substituted for an on -site reading.
Failure to monitor quarterly per permit terms may result in the Division requiring
monthly monitoring for all parameters for a specified ti _,period, as provided in Part II
Section B.
Monitoring results shall be compared to the benchmark values -in Table 6. The benchmark
values in Table 6 are not permit limits but should;be,used as guidelines for the permittee's
Stormwater Pollution Prevention Plan (SPPP)..Exceedances of benchmark values require
the permittee to increase monitoring, increase management actions, increase record

Hi Glen,
It was nice meeting you the other day at the Chemol site visit. I hope we didn't overwhelm you with all the fun that is
permit renewal!
I don't know what your process is for following up on facility inspections, but in case you can use them, here are the
notes I took down on Chemol. Mike, Rick, or Sue — please feel free to add to this.
• They would be interested in being covered under general permit NCG06 rather than an individual permit, if
that's appropriate. Their SIC code 2869 is not specified in the NCG06, but we can discuss whether their
operation is similar enough to be covered under NCG06. I think you may be able to search in BIMS for other
facilities with that SIC code and see what permits they have.
• They have at least two outfalls on their site but have been sampling only one outfall (001) based on approval
from Oct 1993 letter which may have only been applicable during application process. The problem with
sampling only Outfall 001 is that it only receives stormwater from employee parking and roof, and not from the
industrial areas. Outfall 002 is inaccessible, however, and there didn't appear to be an alternative sampling
location upland. Suggest documenting these findings in a new letter granting ROS with added housekeeping
measures on the back side of the property that would include having a spill kit, cleaning grease/oils from metal
stairs and other areas, modifying tank filling procedures so grease doesn't spill down sides, etc.
• No data during some of the sampling periods. They should get sample kits so facility staff can collect samples
after rainfall events.
• pH was outside benchmark range in at least one sample. This could be because the collected sample is not
being tested for pH in a timely manner. The sample should be analyzed within 15 minutes of collection (see
attached guidelines).
• They need to document that they're doing annual spill response reviews.
Thanks again for helping with the individual permit renewals. Feel free to call or email any time with
questions. Bethany is a great resource as well.

Sorry Aana, here is the report that Mr. Newlin sent me the other day. According to our joint schedule, the next
inspection by you all (DENR) is for 1/31/2016. 1 would say, that we give them a little time and maybe you all could
inspect them in another year from my inspection (10/9/13). If they have another spill in the next couple of months, then
I guess we could discuss about doing one sooner.

Aana,

AW
I am sending you some of the email correspondence b/w Mr. Newlin and myself. This was probably one of the most
frustrating inspections I've been on since we started doing these. He first brought out his Spill Response plan and tried
to argue with me that was Chemol's SWP3, I had previously been on an inspection of this facility with Corey B and knew
they had one. William had a copy of their Permit and we had to go through each bullet point of what is required. The
same held true for the Qualitative monitoring reports....see our email conversation below. After I completed the walk
through, he then produced the out dated SWP3 plan.
To answer your question, they have not verbally stated that they are going to correct the problem as it relates to the old
valve and the leaking product. It must be a small leak as product is not actively leaving their site. I plan to follow-up in a
couple weeks to make sure they are making plans to correct the issue and will keep you in the loop. Peter

Hi Debbie,
Sorry for the delay — I was out of the office all day on Friday and didn't get a chance to check my email until now.
Anyway, looks like the last time Chemol was inspected was 8/31/2010 by Corey. I couldn't find his inspection letter, but
have attached the inspection report and Chemol's response, in case that can provide some additional information as to
their situation at the time. Looks like Corey wrote them an NOV for lack of qualitative and analytical monitoring.
Thanks! lust let me know if there's anything else I can do!

Okay. We'll just look at it as two different facilities, and Chemol is up for us this year. Chemol is on our radar for other
stuff, so I'm sure stormwater folks have had interactions with them.

. t
Aana, will you send me past inspection information from when Chemol (NCS000048) was last inspected by your folks? i
would greatly appreciate that!
Many thanks for your help. And I agree with Mike Mickey!

Subject: RE: Valley Proteins in GSO
Both companies are run separately but it does took they both lease property from the same owner (Carolina By-
products). I didn't realize that during my inspection. During my inspection of VP, they believed that runoff from Chemol
had led to some of their past COD exceedences, and said they had had City personnel out there to address it in the past.
It is complicated by the fact that VP maintains property on both sides of the Chemol process buildings, and has SW
outfalls on both sides.
I'm not sure how you could put them both under one permit since they are two different types of business... would have
to be an individual permit, which would just be a mix of the two existing permits.
As Mike Mickey would say... 'Clear as Mud'.

Subject: Valley Proteins in GSO

I'm trying to figure out the relationship between two facilities in Greensboro:
NCG060131, Valley Proteins (was Carolina By -Products), 2410 Randolph Ave., inspected by Jenifer this year
NCS000048, Chemol, 2300 Randolph Ave.
Although the addresses are different, maps do not show a 2300 parcel on Randolph Avenue. Chemol's website gives the
2300 address and indicates it was formed as the chemical division of Carolina By -Products. All info I can find shows these
two facilities as seemingly the same, yet they both have a permit. Is Chemol a totally different entity than Valley Proteins
and is just located on their property? When Valley Proteins is inspected, is Chemol also inspected?
Any light you can shed on this would be greatly appreciated! If it's unclear to you as well, let me know that too and I'll
see if I can find out anything via another route.
Many thanks for your help. O

Hi Peter,
It was great hearing from you today! Chemol's permit expired in 2012, and although they submitted an application for
renewal in 2011, it has still not been renewed by Central Office yet. See attached for a copy of the permit under which
they are currently covered. Because they're still covered under this older permit, it doesn't have the newer significant
spill language I gave you over the phone earlier, which is found on our more recent permits (see below):
The permittee shall report to the local DWQ Regional Office, within 24 hours, all significant spills as defined in Part IV of
this permit. Additionally, the permittee shall report spills including: any oil spill of 25 gallons.or more, any spill regardless of
amount that causes a sheen on surface waters, any oil spill regardless of amount occurring within 100 feet of surface
waters, and any oil spill less than 25 gallons that cannot be cleaned up within 24 hours.
The reporting requirements for Chemol's permit are found on page 8 of the PDF and the definition of significant spills is
on page 27. i guess Chemol would still go by the old definitions, since that's what's written in their permit. I'm going to
ask Raleigh where they are on getting this permit renewed, since it's been almost two years since the application was
received.
Hope that helps! I keep finding old permits like this that Raleigh hasn't finished renewing, so if you find any more please
let me know.
Thanks,

Dear Mr. Wellons:
Dee Freeman
Secretary
In accordance with your completed application received October 16, 2012, we are
forwarding herewith Permit No. 03298RIO to Chemol Company, Inc., Greensboro, Guilford
County, North Carolina for the construction and operation of air emissions sources or air cleaning
devices and appurtenances. Additionally, any emissions activities determined from your air permit
application as meeting the exemption requirements contained in 15A NCAC 2Q .0102 have been
listed for information purposes as an "ATTACHMENT" to the enclosed air permit. Please note the
records retention requirements are contained in General Condition 2 of the General Conditions and
Limitations.
If any parts, requirements, or limitations contained in this permit are unacceptable to you,
you have the right to request a formal adjudicatory hearing within 30 days following receipt of this
permit, identifying the specific issues to be contested. Such a request will stay the effectiveness of
the entire permit. This hearing request must be in the form of a written petition, conforming to G.S.
150B-23 of the North Carolina General Statutes, and filed with the Office of Administrative
Hearings, 6714 Mail Service Center, Raleigh, NC 27699-6714. The form for requesting a formal
adjudicatory hearing may be obtained upon request from the Office of Administrative Hearings.
Unless a request for a hearing is made pursuant to G.S. 150B-23, this air permit shall be final and
binding.
You may request modification of your air permit through informal means pursuant to G.S.
15013-22. This request must be submitted in writing to the Director and must identify the specific

provisions or issues for which the modification is sought. Please note that the permit will become
final and binding regardless of a request for informal modification unless a request for a hearing is
also made under G.S. 150B-23.
Unless exempted by a condition of this -permit or the regulations, construction of new air
pollution sources or air cleaning devices, or modifications to the sources or air cleaning devices
described in this permit must be covered under a permit issued by the Division of Air Quality prior
to construction. Failure to do so is a violation of G.S. 143-215.108 and may subject the Permittee to
civil or criminal penalties as described in G.S. 143-215.114A and 143-215.114B.
This permit shall be effective from October 22, 2012 until September 30, 2017, is
nontransferable to future owners and operators, and shall be subject to the conditions and limitations
as specified therein.
Changes have been made to the permit stipulations. The Permittee is responsible for
carefully reading the entire permit and evaluating the requirements of each permit stipulation. The
Permittee shall comply with all terms, conditions, requirements, limitations and restrictions set forth
in this permit. Noncompliance with any permit condition is grounds for enforcement action, for
permit termination, revocation and reissuance, or modification, or for denial of a permit renewal
application. Specific changes and additions, except for those already communicated with the
facility, are summarized below. Please note that this list may not include all changes and additions
to the permit.
1. Since the condition requiring compliance with 15A NCAC 2D .0515 "Particulates from
Miscellaneous Industrial Processes" was inadvertently removed from the permit during
the last revision, it was placed back in the permit for this revision. Please see permit
condition AA for details.
2. A condition requiring compliance with 15A NCAC 2D .0540 "Particulates from Fugitive
Dust Emission Sources" was added to the permit. Please see permit condition A.9 for
details.
The condition requiring compliance with 15A NCAC 2D .0958 "Work Practices for
Sources of Volatile Organic Compounds (VOC)" was revised to include requirements
when cleaning parts with a solvent containing VOC. Please see permit condition A.I I
for details.
4. A condition reiterating the facility's avoidance of 40 CFR Part 63, Subpart JJJJJJ —
National Emission Standards for Hazardous Air Pollutants for Area Sources: Industrial,
Commercial, and Institutional Boilers, was added to the permit. Please see permit
condition A.14 for details.
5. Permit Condition B.1 was revised. Please see said condition for details.
6. Regarding your letter dated September 24, 2012 requesting that this office determine
whether a modification to the air quality permit is necessary for the trial batch of fatty
ester using Specially Denatured Alcohol SDA 2-B (ethanol denatured with 0.5%

heptane), in light of the information provided, personnel of the Division of Air Quality
have reviewed your letter relative to applicability to air quality permits and determined
that the trial batch qualifies for exemption from permitting per 15A NCAC 02Q
.0102(c)(1)(C)(1v) — research and development laboratory activities provided the activity
produces no commercial product or feedstock material. Therefore, this office has
determined that a modification to the air quality permit is not required for the trial batch.
It should be noted that this exemption from the permitting requirement does not exempt
Chemol Company, Inc. from complying with the applicable emissions control standards.
It is also noted that should the trial batch no longer qualify for exemption from
permitting per the exemption regulation cited above (e.g. commence to produce
commercial product), the trial batch must be re-evaluated for permit applicability.
Emissions resulting from R&D activities are not generally required to be accounted for
on facility -wide emission summaries, but may be required at the Director's discretion.
Furthermore, should you decide to modify the process, an air quality permit modification
may be required and Chemol Company, Inc. should submit a permit modification
application to this office prior to such actions.
This exemption from the permitting requirement is based upon the information provided
to the DAQ. As previously mentioned in this cover letter, the operation of any air
pollution emission sources which results in emissions in excess of the threshold levels
without an air quality permit is a violation of 15A NCAC 02Q .0101, "Required Air
Quality Permits." If this facility is required to obtain a modification to the air quality
permit for this equipment in the future, each day of operation of the emission sources
without an air quality permit represents a separate violation. Such violations may be
subject to enforcement action, including a civil penalty of up to $25,000 per violation
and/or injunctive relief, pursuant to NCGS 143-215.114A.
Should you have any questions concerning this matter, please contact Christopher W.
Lewter, P.E. at [phone].

This permit is subject to the following specified conditions and limitations including any
TESTING, REPORTING, OR MONITORING REQUIREMENTS:
A. SPECIFIC CONDITIONS AND LIMITATIONS
Any air emission sources or control devices authorized to construct and operate above must
be operated and maintained in accordance with the provisions contained herein. The
Permittee shall comply with applicable Environmental Management Commission
Regulations, including Title 15A North Carolina Administrative Code (NCAC), Subchapter

Subject: Draft NPDES Stormwater Permit
Permit No. NCS000048
Chemol Company, Inc
Guilford County
Dear Mr. Newlin:
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 1I, Section B. This term is different
from the "representative storm event" in earlier permits.
2. Tiered responses have been added to this 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 in accordance with Part II, Section B. of this permit.
3. Requirements for the Stormwater Pollution Plan (SPPP) have been updated in Part II,
Section A.
4. 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 Stonnwater Pollution Prevention Plan (SPPP). A benchmark
exceedance is not a permit violation; however, the permittee must respond to
exceedances as directed in the Tiers.
• The Total Phosphorus benchmark has been changed from 5 mg/L to 2 mg/L
for consistency with other industrial stormwater permits as well as wastewater
permit limits imposed on dischargers in Nutrient Sensitive Waters areas.

• 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.
5. A new section on Special Conditions has been added in Part I1, 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.
6. Civil and administrative penalty amounts have been updated to reflect current
federal law in Part III, Section A, 2(b) and (g).
This facility has not been granted Representative Outfall Status; as such, sampling must be
done at both stormwater discharge outfalls identified at this facility. Note that the facility's
current permit as well as this draft permit require quarter! monitoring at all outfalls.
It is important to ensure that pH is tested onsite at the time of collection using apH meter as
delaying this test could return pH levels that are not representative of the onsite conditions.
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
julie.ventaloro(amcderingov or mailed to my attention at NCDEQ, Land Quality Section,

I'm thinking Chemol probably should be under the individual permit. I agree that they need to be collecting where
they've got the highest contamination. Any I thought the site was a safety hazard on several levels. Even the asphalt
has that film on it. It reminded me of candle wax but on everything and I bet it's all flammable.
I'll be in the office again tomorrow if you want to try to get into this and figure out where to go from here
Thank you for helping me so much Julie.

Glen,
I talked with Ken a little more about the Chemol site. We didn't discuss whether they would fit into NCG06, but I will try
to catch up with him about that later. But he did suggest that we hold them to the requirement to collect and test
stormwater from the area of their site with the most potential for stormwater contamination. This may involve
establishing a new collection point. Apparently, this is something we have required of others in some cases. Ken did not
agree with the facility's assessment that grease doesn't migrate, so it is a concern that there is so much grease
deposited around portions of the site.
We can discuss further when you're ready to dig into it.

Dear Corey,
It was good to talk to you on Tuesday. As a follow up to the 2010 audit of Chemol Companies
Strom Water Permit concerning the 2009 reports and the 2 d quarter report for 2010. Due to an oversight
Chemol did not have a contract with Operations Excellence to do Storm Water Testing for 2009 as I
thought. Therefore I am informing you that Chemol Company, Inc. is in violation of its Storm Water
Permit #NCS000048 for the year 2009 due to the fact that no sampling was done. (Please note it was an
oversight, if the renewal notice was received 1 missed it.)
The results for the second quarter 2010 sampling will arrive on Friday 9/3/10. 1 will scan and send
a copy of these results the same day.
Please let me know what 1 need to do as a result of this.
Sincerely,

Chemol Company has received the Notice if Violation — Compliance Evaluation Inspection for
NPDES Permit No. NCS000048 dated September 7, 2010. As requested, Chemol has addressed the
violations as noted below.
Chemol acknowledges that it is in violation of the requirements for permit NCS000048 for the year
2009. In the transition of duties from Mark Heimberger to William Newlin in 2008 the renewal of our
contract with Operations Excellence was overlooked. We are under contract with Operations Excellence for
the year 2010 testing and are currently in compliance with our permit.
Concerning the qualitative monitoring requirements, the reports submitted do have on page 1, "The
findinas and recommendations of this inspection summary." This page summary appears to meet the
requirements of the permit. I have included copies for your review. Based on this Chemol does not feel it is
in violation of the qualitative monitoring requirements. We have requested that future reports use a form
format.
Please find the attached letter date October 27, 1993 approving the use of the #001 outfall as a
Representative Outfall Status.
Feel free to contact me with any questions.

Storm }eater inspection report
The North Carolina NPDES Stormwater Discharge Pen -nit for Chemol requires semi-annual inspections
of the plant's storm water management systems. On August 19, 2010. OEI inspected the plant,
conducted an inventory of significant exposed materials and performed visual monitoring of stonn
water. Several photographs relevant to the inspection are included in this report.
The findings and recommendations of this inspection are summarized as follows:
• A small amount of storm water was noted around the facility. No staining, discoloration or odor
was noted from the observed storm water. There was no evidence of herbicide usage along any
outfall. Several material spills were seen safely within the plant drainage area. The overall
condition of the facility shows that there are no significantly exposed materials (Photos la-ld).
• There are still exposed drums at the rear of the facility (Photos 2a-2b). These drums should be
removed or stored in a covered area. Open drums may be used as a dumping location for used
oil containers or oily debris. This material could contaminate runoff if the drums overfill.
• The drum storage area was nearly empty and in good condition (Photos 3a-3b). There are no
signs of a spill or other pollution. The piping and containers seen in this area appear to be
intact and in -ood condition.
• The dock area near the street is in good condition (Photos 4a-4b). No open drums, spills or
signs of pollution were noted.
• The pallet storage area is in good condition (Photo 5a). One piece of equipment was seen in
this area (Photo 5b). OEI recommends this item be covered or stored elsewhere.
• The AST areas appear to be in good condition. with spills and residue still within the
containment dikes (Photos 6a-6d).
• There appears to be a small amount of material spilled in the railcar area (Photo 7). This should
be checked and the material removed.
• A small spill was seen in an area where runoff would flow into the street (Photo 8).
OEI recommends that this material be cleaned up as soon as possible.
This report should be filed xvith the planVs copy of the Stormwater Pollution Prevention Plan.
This documentation must be retained onsite for a period of five (5) years and made available to the

conducted an inventory of significant exposed materials and performed visual monitoring of storm
% pater. Several photographs relevant to the inspection are included in this report.
The findings and recommendations of this inspection are summarized as follows:
• The front dock and storage area is in overall good condition. However; there were small
amounts of spilled production materials in this area (Photos la-Ic). These spills should be
cleaned up as soon as possible to prevent runoff contamination.
• Several small spills were noted near the front of the facility (Photos 2a-2c). One part of the dike
in this same area has the potential for a spill (Photo 2d). These spills should be cleaned up as
soon as possible to prevent runoff contamination.
• The drum storage area was locked and in good condition (Photos 3a-3d). There are no signs
of drum leakage or other pollution. Open or leaking drums were not observed.
• Other outdoor storage areas and storage containers near a secondary facility entrance were in
good condition (Photos 4a-4c).
• Small spills were observed on the railroad tracks at the rear of the facility (Photo 5).
These spills should be cleaned up as soon as possible to prevent runoff contamination.
• Overall AST areas were in good condition. The rear AST areas had some spills, but these were
contained inside the dike (Photos 6a-6c).
• Several uncovered drums were found in the rear area of the facility (Photos 7a-7c). OEI
recommends that these drums be covered or removed in case there is a containment overflow.
• The overall condition of the facility shows that there are no significantly exposed materials.
Open drums of raw materials, products or intermediary materials were stored within the
drainage areas of the facility sump. There were no indications of large spills in runoff areas.

• The integrity of the ASTs and secondary containment are in good condition. The concrete dikes
appear to have been emptied recently (Photos 2a-2b). Care should be taken regarding the
location of small pails (as seen in Photo 2a) so that they are not easily knocked over outside the
dike, dumping contents that would go into a runoff area.
• The drum storage area was locked and in good condition (Photos 3a-3c). . There are no signs
of drum leakage or other pollution. Open drums were not observed. A small amount of spilled
material was noted next to the drum storage area (Photo 3d). Materials spilled in this area could
easily contaminate runoff. OEI recommends that any spills such as this be cleaned up as soon
as possible.
• The trash bin near the street was not overfilled or subject to overflo%v (Photo 4).
• The pallet storage area is in generally good condition (Photos 5a-5b). Uncovered equipment is
still being stored in this area (Photo 5c). Equipment left outside should be covered or checked
to ensure that they have no oil or chemical residues.
• A few drums were observed in the dock area (Photo 6). They are properly stored in a covered
area. There were no signs of pollution in the immediate area of these drums.
• Process areas appear to be in normal condition (Photos 7a-7d), Since these areas drain into the
facility. OEI does not currently see runoff issues in these locations.
• There is a spill near the dock area that appears to be an oil leak (Photos 8a-8b). This should be
cleaned up as soon as possible. OEI recommends that absorbents be kept near this area for
possible future leaks since this location does not drain into the plant but towards the street.
Leaks here could drain past a covered area and become a source of runoff pollution.

• The integrity of the ASTs and secondary containment are in good condition. Rain water plus
any tank / process discharged was still contained within all of the respective concrete dikes.
However, OEI recommends that contamination in these areas be removed in the near future to
prevent spills should the containment areas overflow.
• Process areas appear to be in normal condition (Photos 2a-2e). Since these areas drain into the
facility, OEI does not currently see runoff issues in these locations.
• The drum storage area was locked and in good condition. Collected rain water within the dike
showed no signs of drum leakage or other pollution. There were no open drums. Other drums
left outside had lids / bungs in place (Photos 3a-3b).
• The trash bin near the street was not overfilled or subject to overflow (Photo 4).
• Some equipment and piping had been left outside without a cover (Photos 5a-5c). Equipment
left outside should be checked to ensure that they have no oil or chemical residues.
• A few drums were observed (Photos 6a-6b). They are properly stored in a covered area. There

Dear Permittee:
Your facility is currently covered for stormwater discharge under NPDES Permit NCS000048. This permit expires
on November 30, 1999. 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 supplemental information will constitute your application for renewal
of your permit. The application form must be completed and returned along with all requested information by June
14, 1999 in order to constitute a timely renewal filing.
Recent legislation modified the fee structure for DWQ permits. Renewal fees have been eliminated and annual fees
have been changed. The new annual fee for your permit is now $715.00 (you will be invoiced later this year for
your annual fee.) A copy of the new fee schedule is enclosed in this package.
Failure to request renewal by June 14, 1999 may result in a civil assessment of at least $250.00. Larger penalties
may be assessed depending on the delinquency of the request. Discharge of stormwater from your facility without
coverage under a valid stormwater NPDES permit would constitute a violation of NCGS 143-215.1 and could
result in assessments of civil penalties of up to $10,000 per day.

General Statute 143-215 .1 and the Memorandum of Agreement between North Carolina and the
US Environmental Protection agency dated December 6, 1983.
Please note that the Division has revised the analytical monitoring strategy for individual
stormwater permits. Based on a review of the permit monitoring data received to date, the
analytical monitoring measurement frequencies have been changed and cut-off concentrations
have been removed. These changes will be implemented for all second term individual
stormwater permits with analytical monitoring requirements. For those permits with analytical
monitoring requirements, Part 11- Monitoring, Controls, and Limitations for Permitted
Discharges has been modified to reflect the change in monitoring strategy.
The qualitative monitoring strategy remains the same as the first term of the permit.
Please note that the semi-annual qualitative monitoring is a requirement of the permit. Failure to
complete the monitoring as required is a violation of the permit and any permit noncompliance
constitutes a violation of the Clean Water Act. Reference Part H, Section A, Item 2 "Duty to
comply", Item 9 'Penalties for Tampering " and Item 10 'Penalties for Falsification of Reports"
of your permit for further information.

the Plan. This Plan shall be considered public information in accordance with Part III. Standard
Conditions, Section E. Paragraph 3 of this individual permit. The Plan shall include. at a
minimum, the following items:
Site Plan. The site plan shall provide a description of the physical facility and the
potential pollutant sources which may be expected to contribute to contamination of
stormwater discharges. The site plan shall contain the following:
(a) A general location map (USGS quadrangle map or appropriately drafted
equivalent map), showing the facility's location in relation to transportation
routes and surface waters, the name of the receiving water(s) to which the
stormwater outfall(s) discharges, or if the discharge is to a municipal separate
storm sewer system. the name of the municipality and the ultimate receiving
waters: and accurate latitude and longitude of the point(s) of discharge.
(b) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes. and
waste disposal practices. y
(c) A site map drawn to scale with the distance legend indicating location of
industrial activities (including storage of materials.. disposal areas, process areas
and loading and unloading areas), drainage structures, drainage areas for each
outfall and activities occurring in the drainage area. building locations. existimz
BIVIPs and impervious surfaces, and the percentage of each drainage area that is
impervious. For each outfall. a narrative description of the potential pollutants
which could be expected to be present in the stormwater discharge.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the 3 previous years and any corrective actions taken to mitigate spill
impacts.
(e) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The certification statement will be signed in
accordance with the requirements found in Part III, Standard Conditions, Section
B, Paragraph 3,
2. Stormwater Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, at a minimum. `hall
incorporate the following:
Part H Pa17e 1 of 6

Permit No. NCS000048
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. Wherever practical, the permittee shall
prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations. In areas where elimination of exposure is
not practical, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
(b) Secondary Containment Schedule. A schedule to provide secondary containment
for bulk storage of liquid materials, storage of Section 313 of Title III of the
Superfund Amendments and Reauthorization Act (SARA) water priority
chemicals, or storage of hazardous substances to prevent leaks and spills from
contaminating stormwater runoff. If the secondary containment devices are
connected directly to stormwater conveyance systems, the connection shall be
controlled by manually activated valves or other similar devices [which shall be
secured with a locking mechanism] and any stormwater that accumulates in the
containment area shall be at a minimum visuallv observed for color, foam, outfall
staining. visible sheens and dry weather flow, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated by the material stored within the containment area. Records
documenting the individual making the observation, the description of the
accumulated stormwater and the date and time of the release shall be kept for a
period of five years.
(c) BVIP Summary. A narrative description shall be provided of Best Management
Practices (BylPs) to be considered such as, but not limited to. oil and grease
separation, t cbris control, vegetative filter strips, infiltration and stormwater
detention or retention, where necessary. The need for structural BN1Ps shall be
based on the assessment of potential of sources to contribute significant quantities
of pollutants to stormwater discharges and data collected through monitoring of
stormwater discharges. y
3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or team) responsible for implementing the
SPRP shall be identified. A responsible person shall be on -site at all times during facility
operations that have the potential to contaminate stormwater runoff through spills or
exposure of materials associated with the facility operations. The SPRP must be site
stormwater specific. Therefore, a SPCC plan may be a component of the SPRP, but may
not be sufficient to completely address the storrnwater aspects of the SPRP. The common
elements of the SPCC with the SPRP may be incorporated by reference into the SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance program shall be developed. The program shall document schedules of
inspections and maintenance activities of stormwater control systems, plant equipment
and systems. Inspection of material handling areas and regular cleaning schedules of
these areas shall be incorporated into the program. 4

also made two additional changes in the permit to reflect Division policy changes in the Stormwater
Program. These changes add flexibility to the permit by the elimination of the "sampling window;+" (page
8, Footnote 1, Measurement Frequency) to allow samples to be collected at any time during the year, and
by changing the definition of a Representative Storm Event (page A3). All other terms and conditions in
the original permit remain unchanged and in full effect. Such terms and conditions include the original
completion date of the Stormwater Pollution Prevention Plan back on March 23, 1996. This permit
modification is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the
Memorandum of Agreement between North Carolina and the U. S. Environmental Protection Agency
dated December 6, 1983.
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30)
days following receipt of this letter. This request must be in the form of a written petition, conforming to
Chapter 150B of the North Carolina General Statutes, and filed with the Office of Administrative
Hearings, Post Office Drawer 27447, Raleigh, North Carolina 27611-7447. Unless such demand is
made, this decision shall be final and binding.

authorized representative immediately upon request.
2. Minimum Monitoring and Reporting Requirements
Minimum monitoring and reporting requirements are as follows unless otherwise approved in
writing by the Director of the Division of Water Quality.
a. If a facility has multiple discharge locations with substantially identical stormwater
discharges that are required to be sampled, the permittee may petition the Director for
representative outfall status. If it is established that the stormwater discharges are
substantially identical and the permittee is granted representative outfall status, then
sampling requirements may be performed at a reduced number of outfalls.
b_ Visual monitoring for color, odor, solids, foam, outfall staining, visible sheens and dry
weather flow shall be performed at all stormwater discharge outfall locations. All visual
monitoring shall be documented and records maintained with the Stormwater Pollution
Prevention Plan. The initial visual monitoring event shall be performed simultaneously
Page 6

Permit No. NCS000048
with the first analytical monitoring event and documentation of only this initial visual
monitoring event shall be submitted along with the required analytical monitoring submittal.
C. For purposes of the stormwater sampling required in this permit, all samples shall be
collected from a discharge resulting from a representative storm event (See Part II,
Standard Conditions, Section A). Failure to monitor storm events in accordance with the
specified frequency shall constitute a violation of this permit. If the stormwater runoff is
controlled by a detention pond, the following sampling requirements shall apply:
(1) If the detention pond detains the runoff generated by one inch of rainfall for 24
hours, visual observations for color, foam, outfall staining, visible sheens, and dry
weather flow are required. but analytical sampling shall not -be required.
(2) If the detention pond discharges only in response to a storm event exceeding a 25-
year, 24-hour storm (See Part II, Standard Conditions, Section A), the pond shall
be considered a non -discharging stormwater control system and not subject to
NPDES requirements, unless the discharge causes a violation of water quality
standards.
d. Samples analyzed in accordance with the terms of this permit shall be submitted on forms
provided by the Director no later than January 31 for the previous year in which sampling
was required to be performed.
e. Analytical results from sampling during the final year of the permit term shall be submitted
with the permit renewal application.
f. This permit regulates stormwater discharges. Non-stormwater discharges which shall be
allowed in the stormwater conveyance system are:
(1) All other discharges that are authorized by a non-stormwater NPDES permit.
(2) Uncontaminated groundwater, foundation drains, air -conditioner condensate
without added chemicals, springs, discharges of uncontaminated potable water,
waterline and fire hydrant flushings, water from footing drains, flows from riparian
habitats and wetlands.
(3) Discharges resulting from fire -fighting.
If the storm event monitored and reported in accordance with this permit coincides with a
—non-stormwater discharge, the permittee shall separately monitor and report all parameters
as required under the non-stormwater discharge permit and provide this information with
the stormwater discharge monitoring report.

For each parameter, the arithmetic mean of all analytical sampling results collected during the
term of the permit shall be calculated for each individual outfall and compared to the cut-off
concentrations listed below. If the arithmetic mean meets the specified cut-off concentration
condition for a given parameter, then the facility is not required to continue annual analytical
monitoring for that parameter at that outfall unless a significant change in facility operations or
configuration occurs. if a cut-off concentration results in discontinued analytical monitoring at
an individual discharge outfall, the permittee is required to maintain facility operations that
ensure the continuation of stormwater runoff quality.
The permittee must perform analytical sampling during the first and last year of the permit term
regardless of cut-off concentration conditions. Analytical results from sampling during the
final year of the perrnit term must be submitted with the permit renewal application.

During the period beginning on the effective date of the permit and lasting until expiration, the
Permittee is authorized to discharge stormwater associated with industrial activity. 'Such
discharges shall be controlled, limited and monitored as specified below.
1 _ Stormwater Pollution Prevention Plan
The Permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as the
Plan. This Plan shall be considered public information in accordance with Part H, Standard .
Conditions, Section EX of this permit. The Plan shall include, at a minimum, the following
items:
a. 'Site Plan. The site plan shall provide a description of the physical facility and the potential
pollutant sources which may be expected to contribute to contamination of stormwater
discharges. The site plan shall -contain the following:
(1) A.general location map (USGS quadrangle map or appropriately drafted equivalent
map), showing the facility's location in relation to transportation routes and surface
waters, the name of the receiving water(s) to which the stormwater outfall(s)
discharges, or if the discharge is to a municipal separate storm sewer -system, the
name of the municipality and the ultimate receiving waters; and accurate latitude
and longitude of the point(s) of discharge.
(2) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste -disposal .practices.
(3) A site map drawn to scale with the distance legend indicating location of industrial
activities (including storage of materials, disposal areas, process areas and loading
and unloading areas), drainage structures, drainage areas for each.outfall and
activities occurring in the drainage area,(including delineation of public storm drain
grates and actual outfalls), building locations and impervious surfaces, and the
percentage of each drainage area that is impervious. For -each outfall, a narrative
description of the potential pollutants which,could be -expected to be present in the
stormwater discharge.
(4) A list of -significant -spills or leaks of pollutants that have occurred at the facility
during the 3 previous years and any -corrective actions taken to mitigate spill
impacts.
-;(5) Certification that the stormwater outfalls have -been• evalua tedfor the presence -of
non-stormwater discharges. The certification statement will be signed in
accordance with the requirements found in •Part L Standard Conditions, Section
-$.9:

Permit No. NCS000048
b. Stormwater Management Plan. The stormwater management plan shall contain a narrative
description of the materials management practices employed which control or minimize the
exposure of significant materials to stormwater, including structural and nonstructural
measures. The stormwater management plan, at a minimum, shall incorporate the
following:
(1) A study addressing the technical and economic feasibility of changing the methods
of operations and/or storage practices to eliminate or reduce exposure of materials
and processes to stormwater. Wherever practicable the -permittee shall cover all
storage areas, material handling operations, manufacturing or fueling operations to
prevent materials exposure to stormwater. In areas where elimination of -exposure
is not practicable, the storrrrwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
(2) A schedule to provide secondary containment for bulk storage of liquid materials,
storage of Section 313 of Title III of the Superfund Amendments and
Reauthorization Act (SARA) water priority chemicals, or storage of hazardous
materials to prevent leaks and spills from contaminating stormwater runoff. If the
secondary containment devices are connected directly to stormwater conveyance
systems, the connection shall be controlled by manually activated valves or other
similar devices [which shall be secured with a locking mechanism] and any
stormwater that accumulates in the containment area shall be at a minimum visually
observed for color, foam, and visible sheens, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated. Records documenting the individual making the- observation, the
description of the accumulated stormwater and die -date and time of the release shall
be kept for a period of five years.
Q) A narrative description shall be provided of Best Management Practices.(BMPs) to
be considered such as, but not limited to, oil and grease separation, debris control,
vegetative filter strips, infiltration and stormwater detention or retention, where
necessary. The need for structural BMPs shall be based on the assessment of
potential of sources to -contribute significant -quantities of pollutants to stormwater
discharges and data collected through monitoring of stormwater discharges.
(4) Inspection schedules of stormwater conveyances and controls and measures to be
taken to limit or prevent -erosion associated with the stormwater systems.
c. 'Spill Prevention -and Response Plan. The -Spill -Prevention and Response Plan shall
incorporate a risk -assessment of•potential pollutant sources based on a materials inventory
of the facility. Facility personnel .(or team) responsible for implementing the plan shall be
identified in the plan. A responsible person shall be,on-site at all times during facility

a. If a•facility has multiple discharge locations with substantially identical stor nwater
discharges that are required to be sampled, the-per-mittee may petition the Director for
representative outfall status..If it is established that the stormwater discharges are
substantially identical and the permittee is -granted representative outfall status, then
sampling requirements may be perfornied.at a reduced number of outfalls.
b. Visual monitoring for color, odor, solids,>foam, outfall-staining, visible -sheens and dry..
weather flow shall be performmd at all stoirnwater•discharge outfall locations. All visual
monitoring -shall be documented and"records maintained with the Stormwater.Pollution
-.Pmvention'Plan. The -initial visual monitoring event shall -be performed simultaneously

Pen -nit No. NCS000048
with the first analytical monitoring event and documentation of only this initial visual
monitoring event shall be submitted along with the required analytical monitoring submittal.
c. For purposes of the stormwater sampling required in this permit, all samples shall be
collected from a discharge resulting from a representative storm-evenv(SeeTart H,
Standard Conditions, Section A). Failure to monitor storm, events in accordance with the
specified frequency shall constitute a violation of this permit. If the-stormwater runoff is
controlled by a detention pond, the following sampling requirements shall apply:
(1) If the detention pond detains the runoff generated by one inch of rainfall for 24
hours, visual observations for color, foam, outfall staining, visible sheens, and dry
weather flow are required, but analytical sampling shall noube required.
(2) If the detention pond discharges only in response to a storm event�exceeding a 25-
year, 24-hour storm.(See Part II, Standard Conditions, Section A), the pond -shall
be considered a non -discharging stormwater control system and not subject to
NPDES requirements, unless the discharge causes'a violation -of water quality
standards.
d. Samples analyzed in accordance with the terms of this permit shall be submitted on forms
provided by the Director no later than January 31 for the previous year in which sampling
.was required to be performed.
e. Analytical results from sampling during the: final year of the permit term shall be submitted
with the permit renewal application.
f. This permit regulates stormwater discharges. Non-stormwater discharges which shall be
allowed in the stormwater conveyance system are:
_-(1) All other discharges that are authorized by a non=stormwater NPDES permit.
-(2) Uncontaminated-roundwater, foundation drains, air -conditioner condensate
without added chemicals, springs, discharges of uncontaminated potable water,
waterline and fire hydrant.flushings, water from footing drains, flows from riparian
habitats and wetlands.
.(3) 'Discharges resulting from fire -fighting.
If the storm event monitored and reported in accordance with this permit coincides with a
- r non-stormwater discharge, the permittee shall separately monitor and report all parameters
as required under the non-stormwater discharge permit and provide this information with
the stormwater discharge monitoring report.

�� a■, r •� •�■ �.
The permittee shall at all times properly operate and maintain all facilities and
systems of treatment and control (and related appurtenances) which are installed or
used by the permittee to achieve compliance with the conditions of this permit.
Proper operation and maintenance also includes adequate laboratory controls and
appropriate quality assurance procedures. This provision requires the operation of
back-up or auxiliary facilities or similar systems which are installed by a permittee
only when the operation is necessary to achieve compliance with the conditions of
the permit
2. Need to H2-!t or Reduce not a Demme
It shall not be a defense for a permittee in an enforcement action that it would have
been necessan. to halt or reduce the permitted activity in order to maintain
compliance with the condition of this permit_
3. Bs-r;a�z`ns:nF of Sto-mw2ter Control Facilities
a. DeLrtitions
(1) "Bypass" means the known diversion of stormwater from any portion of a
stormwater control facility including the collection system, which is not a
designed or established or operating mode for the facility.
(2) "Severe property darnage" means substantial physical damage to property,
damage to the control facilities which causes them to become inoperable, or
substantial and permanent loss of natural resources which can reasonably be
expected to occur in the absence of a bypass. Severe property damage does
not mean economic loss caused by delays in production.
b. Bypass Not Exceeding Limitations.
The perminee may allow any bypass to occur which does not cause limitations to be
exceeded, but only if it also is for essential maintenance to assure efficient
operation. These bypasses are not subject to the provisions of Paragraphs c. and d.
of this section.
c. Notice
{1} Anticipated bypass. If the permina knows in advance of the need for a
bypass, it shall submit prior notice, if possible at least ten days before the
date of the bypass; including an evaluation of the anticipated quality and
affect of the bypass.

Individual Stormwater Page Al2
(2) Unanticipated bypass. The permittee shall submit notice within 24 hours of
an unanticipated bypass as required in Part II, E. 5. of this permit. (24-
hour notice).
d. Prohibition of Bypass
Bypass is prohibited and the Director may take enforcement action against a
permittee for bypass, unless:
(1) Bypass was unavoidable to prevent loss of life, personal injury or severe
property damage;
(2) There were no feasible alternatives to the bypass, such as the use of
auxiliary control facilities, retention of storm -water or maintenance during
normal periods of equipment downtime or dry weather. This condition is
not satisfied if adequate backup controls should have been installed in the
exercise of reasonable engineering judgment to prevent a bypass which
occurred during normal periods of equipment downtime or preventive
maintenance; and
(3) The permittee submitted notices as required under Paragraph c. of this
section.
The Director may approve an anticipated bypass, after considering its adverse
effects, if the Director determines that it will meet the three conditions listed above
in Paragraph d. of this section.
4.LSets
a. Definition
"Upset " means an exceptional incident in which there is unintentional and
temporary noncompliance with technology based permit effluent limitations
because of factors beyond the reasonable control of the perinittee. An upset does
not include noncompliance to the extent caused by operational error, improperly
designed treatment or control facilities, inadequate treatment or control facilities,
lack of preventive maintenance, or careless or improper operation.
b. Effect of an upset.
An upset constitutes an affirmative defense to an action brought for noncompliance
with technology based permit effluent limitations if the requirements of paragraph c.
of this condition are met. No determination made during administrative review of
claims that noncompliance was caused by upset, and before an action for
noncompliance, is final administrative action subject to judicial review.
C. Conditions Necessary for a Demonstration of Upset
A perminee who wishes to establish the affirmative defense of upset shall
demonstrate, through properly signed, contemporaneous operating logs, or other
relevant evidence that; .
(1) An upset occurred and that the permittee can identify the cause(s) of the
upset;

Individual Stormwater Page A13
(2) The permitted facility was at the time being properly operated; and
(3) The permittee submitted notice of the upset as required in Part II, E. 5. (b)
(B) of this permit-
(4) The permittee complied with any remedial measures required under Part II,
A. 2. of this permit.
d. Burden of Proof
In any enforcement proceeding the permittee seeking to establish the occurrence of
an upset has the burden of proof.
Samples collected and measurements taken, as required herein, shall be
characteristic of the volume and nature of the permitted discharge. Samples shall be
taken on a day and time that is characteristic of the discharge. All samples shall be
taken before the discharge joins or is diluted by any other waste stream, body of

SUBJECT: NPDES Permit NCS000048
Chemol Co. Div. of CBP Resources
Guilford County
Dear Mr. Spencer:
In accordance with your Petition for a Contested Case Hearing, 94 EHR 1717, dated December 1, 1994,
we are forwarding herewith a redrafted'permit outlining the modifications removing the requirement to
segregate the stormwater runoff from the roadway and the Chemol site runoff. During a site visit, the
Winston-Salem Regional Office staff confirmed that the property where the truck drainage leaks occur is on
the neighboring rendering facility operation and therefore, removal of the condition from the Chemol permit
is appropriate.
It is our understanding that the two facilities, Chemol and Carolina Byproducts are two divisions of CBP
Resources, Inc. If the Division determines that the two permits issued,to,_the.separate divisions, Chemol
(NCS000048) and CBP Resources (NCG060131), do not result in a resolution ofsthe stormwater runoff
problems, the Division may require that one permit be issued to CBP Resources, Inc. to cover both sites.
Attached is a draft of the revised permit. If any terms or conditions proposed by this modification art, -
unacceptable to you, you should notify us by March 20, 1995. If this permit modification is acceptable,
Chemol must complete the attached Notice of Withdrawal of Petition form by March 20, 1995 and submit
one copy to the Attorney General's Office as specified on the withdrawal form and one copy to this .
Division. The original Notice of Withdrawal form should be submitted to the Office of Administrative
Hearings.
When you have withdrawn your request for a Contested Case Hearing, the modified permit will be issued.
If,the proposed modification is not acceptable to you, we will proceed with the adjudicatory process.
If you have any questions or comments, please contact Coleen H. Sullins of the Permits and Engineering
Unit at 919/733-5083 (ext 550).

PART I
MONITORING, CONTROLS, AND LIMITATIONS FOR PERMITTED
DISCHARGES
ECTION A: FINAL LIN41TATIONS AND CONTROLS FOR STORMWATER DISCHARGE
During the period beginning on the effective date of the permit and lasting until expiration, the
Permittee is authorized to discharge stormwater associated with industrial activity. Such
discharges shall be controlled, limited and monitored as specified below.
1. Stormwater P.Q11Uti-on Prevention Plan
The Permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as the
Plan. This Plan shall be considered public information in accordance with Part II, Standard
Conditions, Section E.8. of this permit. The Plan shall include, at a minimum, the following
items:
a. Site Plan. The site plan shall provide a description of the physical facility and the potential
pollutant sources which may be expected to contribute to contamination of stormwater
discharges. The site plan shall contain the following:
(1) A general location map (USGS quadrangle map or appropriately drafted equivalent
map), showing the facility's location in relation to transportation routes and surface
me
waters, the naof the receiving waters) to which the stormwater outfall(s)
discharges, or if the discharge is to a municipal separate storm sewer system, the
name of the municipality and the ultimate receiving waters; and accurate latitude
and longitude of the point(s) of discharge.
(2) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices.
(3) A site map drawn to scale with the distance legend indicating location of industrial
activities (including storage of materials, disposal areas, process areas and loading
and unloading areas), drainage structures, drainage areas for each outfall and
activities occurring in the drainage area (including delineation of public storm drain
grates and actual outfalls), building locations and impervious surfaces, and the
percentage of each drainage area that is imper6ous. For each outfall, a narrative
description of the potential pollutants which could be expected to be present in the
stormwater discharge.
(4) A list of significant spills or leaks of pollutants that have occurred at the facility
during the 3 previous years and any corrective actions taken to mitigate spill
impacts.
(5) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The certification statement will be signed in
accordance with the requirements found in Part II, Standard Conditions, Section
B.9.
Page 4

Permit No. NCSOW048
b . Stormwater Management Plan. The stormwater management plan shall contain a narrative
description of the materials management practices employed which control or minimize the
exposure of significant materials to stormwater, including structural and nonstructural
measures. The stormwater management plan, at a minimum, shall incorporate the
following:
(1) A study addressing the technical and economic feasibility of changing the methods
of operations and/or storage practices to eliminate or reduce exposure of materials
and processes to stormwater. Wherever practicable the permittee shall cover all
storage areas, material handling operations, manufacturing or fueling operations to
prevent materials exposure to stormwater. In areas where elimination of exposure
is not practicable, the stormwater management plan- shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
(2) A schedule to provide secondary containment for bulk storage of liquid materials,
storage of Section 313 of Title III of the Superfund Amendments and
Reauthorization Act (SARA) water priority chemicals, or storage of hazardous
materials to prevent leaks and spills from contaminating stormwater runoff. If the
secondary containment devices are connected directly to stormwater conveyance -
systems, the connection shall be controlled by manually activated valves or other
similar devices [which shall be secured with a locking mechanism] and any
stormwater that accumulates in the containment area shall be at a minimum visually
observed for color, foam, and visible sheens, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated. Records documenting the individual making the observation, the
description of the accumulated stormwater and the date and time of the release shall
be kept for a period of five years.
(3) A narrative description shall be provided of Best Management Practices (BMPs) to
be considered such as, but not limited to, oil and grease separation, debris control,
vegetative filter strips, infiltration and stormwater detention or retention, where
necessary.. The need for structural BMPs shall be based on the assessment of
potential of sources to contribute significant quantities of pollutants to stormwater
discharges and data collected through monitoring of stormwater discharges.
(4) Inspection schedules of stormwater conveyances and controls and measures to be
taken to limit or prevent erosion associated with the stormwater systems.
c. Spill Prevention and Response Plan. The Spill Prevention and Response Plan .shall
incorporate a risk assessment of potential pollutant sources based'on a materials inventory
of the facility. Facility personnel (or team) responsible for implementing the plan shall be
identified in the plan. A responsible person shall be on -site at all times during facility
operations that have the potential to contaminate stormwater runoff through spills or
exposure of materials associated with the facility operations.
d. Preventative Maintenance and Good Housekeeping Program. A preventative maintenance
program shall be developed. The program shall document schedules of inspections and
maintenance activities of stormwater control systems, plant equipment and systems.
Inspection of material handling areas and regular cleaning schedules of these areas shall be
incorporated into the program.
e. Employee Training. Training schedules shall be developed and training provided at a
minimum on an annual basis on proper spill response and cleanup procedures and
preventative maintenance activities for all personnel involved in any of the facility's
Page 5

Permit No. NCS000048
operations that have the potential to contaminate stormwater runoff. Facility personnel (or
team) responsible for implementing the training shall be identified in the Plan.
f. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be documented
and position(s) assignments provided.
9. Plan Ammendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants to surface waters. The Stormwater Pollution
Prevention Plan shall be reviewed and updated on an annual basis.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall
submit a time schedule to the Director for modifying the Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with Part
II, Standard Conditions, Section B, #9) to the Director that the changes have been made.
h . Facility Inspections. Inspections of the facility and all stormwater systems shall occur at a
minimum on a semiannual schedule, once in the fall (September -November) and once
during the spring (April - June). The inspection and any subsequent maintenance activities
performed shall be documented, recording date and time of inspection, individual(s)
making the inspection and a narrative description of the facility's stormwater control
systems, plant equipment and systems. Records of these inspections shall be incorporated
into the Stormwater Pollution Prevention Plan.
Visual monitoring as required in I.A.2.g.(3) shall be performed -in addition to facility
inspections.
Implementation. Implementation of the plan shall include documentation of all monitoring,
measurements, inspections and maintenance activities and training provided to employees,
including the log of the sampling data and of activities taken to implement BMPs associated
with the industrial activities, including vehicle maintenance activities. Such documentation
shall be kept on -site for a period of five years and made available to the Director or his
authorized representative immediately upon request.
2. Minimum Monitoring and Rgortine Requirements
-r
Minimum monitoring and reporting requirements are as follows unless otherwise approved in
writing by the Director of the Division of Environmental Management.
If a facility has multiple discharge locations with substantially identical stormwater
discharges that are required to be sampled, the permittee may petition the Director for
representative outfall status. if it is established that the stormwater discharges are
substantially identical and the permittee is granted representative outfall status, then
sampling requirements may be performed at a reduced number of outfalls.
b . Visual monitoring for color, odor, solids, foam, outfall staining, visible sheens and dry
weather flow shall be, performed at all stormwater discharge outfall locations. All visual
monitoring shall be documented and records maintained with the Stormwawr Pollution
Prevention Plan. The initial visual monitoring event shall be performed simultaneously
Page 6

Permit No. NCS000048
with the first analytical monitoring event and documentation of only this initial visual
monitoring event shall be submitted along with the required analytical monitoring submittal.
C. For purposes of the stormwater sampling required in this permit, all samples shall be
collected from a discharge resulting from a representative storm event (See Part 11,
Standard Conditions, Section A). Failure to monitor storm events in accordance with the

(2) Cut-off Concentrations
For each parameter, the arithmetic mean of all analytical sampling results collected during the
term of the permit shall be calculated for each individual outfall and compared to the cut-off
concentrations listed below. If the arithmetic mean meets the specified cut-off concentration
condition for a given parameter, then the facility is not required to continue annual analytical
monitoring for that parameter at that outfall unless a significant change in facility operations or
configuration occurs. If a cut-off concentration results in discontinued analytical monitoring at
an individual discharge outfall, the permittee is required to maintain facility operations that
ensure the continuation of stormwater runoff quality.
The permittee must performanalytical sampling during the first,and last year of the permit term
regardless of cut-off concentration conditions. Analytical results from sampling during the
final year of the permit term must be submitted with the permit renewal application.

normal periods of equipment downtime or da 3yeather.This condition is
not satisfied if adequate backup controls should have been installed in the
exercise of reasonable engineering judgment to prevent a bypass which
occurred during normal periods of equipment downtime or preventive
maintenance; and
(3) The permittee submitted notices as required under Paragraph c. of this
section.
The Director may approve an anticipated bypass, after considering its adverse
efffec:-s, if the Director determines that it will meet the three conditions listed above
in Paragraph d. of this section.
4. .Z e* _h
Don
"Upset " means an exceptional incident in which there is unintentional and
temporary noncompliance with technology based permit effluent limitations
because of factors beyond the reasonable control of the permittee. An upset does
not include noncompliance to the extent caused by operational error, improperly
designed treatment or control facilities, inadequate treatment or control facilities,
lack of preventive maintenance, or careless or improper operation.
b. Effect of an Upset.
An upset constitutes an affirmative defense to an action brought for noncompliance
with technology based permit effluent limitations if the requirements of paragraph c.
of this condition are met. No determination made during administrative review of
claims that noncompliance was caused by upset, and before an action for
noncompliance, is final administrative action subject to judicial review.
Conditions Necessary for a Demonstration of Upset
A permittee who wishes to establish the affirmative defense of upset shall
demonstrate, through properly signed, contemporaneous operating logs, or other
relevant evidence that . .
(1) An upset occurred and that the permittee can identify the cause(s) of the
upset;

Individual Stormwater Page A13
(2) The permitted facility was at the time being properly operated; and
(3) The permittee submitted notice of the upset as required in Part 11, E. 5. (b)
(B) of this permit-
(4) The permiuce complied with any remedial measures required under Part H,
A. 2. of this permit.

Thanks, Corey.
During your site visit, will you look into the number of outfalls at this facility?
This applicant has been sampling at one outfall, though there are two outfalls noted
on the site plan. On October 27, 1993 the Division granted the applicant permission
to sample at only one of these outfalls in order to collect samples prior to their
first stormwater permit. However, there is no documentation in the file that the
applicant was granted permission to continue sampling only one location during the
permitting cycles to come. It may be the case that they can continue to sample at the
one location, but it is worth looking into.
Thanks,
Kelly

Dear Mr. Heimberger:
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please review
the draft very carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from this facility's current permit:
• pH has been added per DWQ current strategy.
potential lag time between the e`xpiratiori of tliis permif and its renewal; the permittee is
responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1,
4, and 5.
• The flow reporting requirement has been removed from the analytical monitoring requirements
per DWQ revised strategy. Total rainfall and event duration have been retained.
o Benchmarks have been added to this draft permit. These benchmarks are not permit limits but
should be used as guidelines for your Stormwater Pollution Prevention Plan (SPPP). New
language specifies that if any measurements exceed benchmark values, you should evaluate the
effectiveness of its BMPs, review and/or update your SPPP, and document any efforts to address
stormwater contamination. See Part II, Sections B & D.
• All monitoring has been changed to quarterly.
• Vehicle maintenance is not done onsite. However, should you begin these operations, you will
have to sample quarterly.
• Part II Section A has been revised. It now specifies all of the items to include on the site map.
• Please note that there is a qualitative monitoring results form on our website that can help you
summarize all of your required data, http://h2o.enr.state.nc.us/su/Forms_Documents.htm.

PART II MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. This Plan shall be considered public information in accordance with Part III, Standard
Conditions, Section E, Paragraph 3 of this individual permit. The PIan shall include, at a
minimum, the following items:
1. Site Plan. The site plan shall provide a description of the physical facility and the
potential pollutant sources which may be expected to contribute to contamination of
stormwater discharges. The site plan shall contain the following:
a. A general location map (USGS quadrangle map or appropriately drafted
equivalent map), showing the facility's location in relation to transportation
routes and surface waters, the name of the receiving water(s) to which the
stormwater outfall(s) discharges, or if the discharge is to a municipal separate
storm sewer system, the name of the municipality and the ultimate receiving
waters; and accurate latitude and longitude of the point(s) of discharge.
b. A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices.
C. A site map drawn to scale with the following items:
(1) Distance legend and north arrow
(2) Location of industrial activities (including storage of materials,
disposal areas, process areas and loading and unloading areas)
(3) Drainage structures
(4) Delineated drainage areas for each outfall

Permit No. NCS000048
2. Stormwater Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following:
a. Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. Wherever practical, the permittee shall
prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations. In areas where elimination of exposure is
not practical, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
b. Secondary Containment Schedule. A schedule to provide secondary containment
for bulk storage of liquid materials, storage of Section 313 of Title III of the
Superfund Amendments and Reauthorization Act (SARA) water priority
chemicals, or storage of hazardous substances to prevent leaks and spills from
contaminating stormwater runoff. if the secondary containment devices are
connected directly to stormwater conveyance systems, the connection shall be
controlled by manually activated valves or other similar devices [which shall be
secured with a locking mechanism] and any stormwater that accumulates in the
containment area shall be at a minimum visually observed for color, foam, outfall
staining, visible sheens and dry weather flow, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated by the material stored within the containment area. Records
documenting the individual making the observation, the description of the
accumulated stormwater and the date and time of the release shall be kept for a
period of five years.
BMP Summary. A narrative description shall be provided of Best Management
Practices (BMPs) to be considered such as, but not limited to, oil and grease
separation, debris control, vegetative filter strips, infiltration and stormwater
detention or retention, where necessary. The need for structural BMPs shall be
based on. the assessment of potential of sources to contribute significant quantities
of pollutants to stormwater discharges and data collected through monitoring of
stormwater discharges.
3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or team) responsible for implementing the
SPRP shall be identified. A responsible person shall be on -site at all times during facility
operations that have the potential to contaminate stormwater runoff through spills or
exposure of materials associated with the facility operations. The SPRP must be site
stormwater specific. Therefore, a SPCC plan may be a component of the SPRP, but may
Part II Page 2 of 8

Permit No. NCS000048
not be sufficient to completely address the stormwater aspects of the SPRP. The common
elements of the SPCC with the SPRP may be incorporated by reference into the SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance program shall be developed. The program shall document schedules of
inspections and maintenance activities of stormwater control systems, plant equipment
and systems. Inspection of material handling areas and regular cleaning schedules of
these areas shall be incorporated into the program.
5. Employee Training. Training schedules shall be developed and training provided at a
minimum on an annual basis on proper spill response and cleanup procedures and
preventative maintenance activities for all personnel involved in any of the facility's
operations that have the potential to contaminate stormwater runoff. Facility personnel
(or team) responsible for implementing the training shall be identified.
6. Responsible Party. The Stormwater Pollution Prevention PIan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be documented
and position assignments provided.
7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which.has a significant effect on the
potential for the discharge of pollutants to surface waters. The Stormwater Pollution
Prevention Plan shall be reviewed and updated on an annual basis.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall
submit a time schedule to the Director for modifying the Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part III, Standard Conditions, Section B, Paragraph 3) to the Director that the changes
have been made.
8. Facility Inspection Program. Facilities are required to inspect all stormwater systems on
at least a semiannual schedule, once in the fall (September -November) and once in the .
spring (April - June). The inspection and any subsequent maintenance activities
performed shall be documented, recording date and time of inspection, individual(s)
making the inspection and a narrative description of the facility's stormwater control
systems, plant equipment and systems. Records of these inspections shall be incorporated
into the Stormwater Pollution Prevention Plan.
Stormwater discharge characteristic monitoring as required in Part II of this permit shall
be performed in addition to facility inspections.

Part III Page 5 of 8 Pages

Permit No. NCS000048
Representative Outfall
If a facility has multiple discharge locations with substantially identical stormwater discharges that are
required to be sampled, the permittee may petition the Director for representative outfall status. If it is
established that the stormwater discharges are substantially identical and the permittee is granted
representative outfall status, then sampling requirements may be performed at a reduced number of outfalls.
6. Records Retention
Visual monitoring shall be documented and records maintained at the facility along with the Stormwater
Pollution Prevention Plan. Copies of analytical monitoring results shall also be maintained on -site. The
permittee shall retain records of all monitoring information, including all calibration and maintenance
records and all original strip chart recordings for continuous monitoring instrumentation, and copies of all
reports required by this individual permit for a period of at least 5 years from the date of the sample,
measurement, report or application. This period may be extended by request of the Director at any time.

acting as a representative of the Director), or in the case of a facility which discharges through a municipal
separate storm sewer system, an authorized representative of a municipal operator or the separate storm
sewer system receiving the discharge, upon the presentation of credentials and other documents as may be
required by law, to;
a., Enter upon the permittee's premises where a regulated facility or activity is located or conducted,
or where records must be kept under the conditions of this individual permit;
b. Have access to and copy, at reasonable times, any records that must be kept under the conditions of
this individual permit;
C. Inspect at reasonable times any facilities, equipment (including monitoring and control equipment),
practices, or operations regulated or required under this individual permit; and

NCS000048 renewal peer review summary, Chemol Co., Inc.
By kbp for Kelly Johnson
1/24/07
1. File review. NOD from WSRO for non-functioning alarms and pumps, cracked
secondary containment, etc.
2. Data review.
a. Only two drainage outfalls identified, but perhaps four drainage areas exist,
per site plan layout. Should be corrected, or explained.
b. Only one outfall sampled. Permittee mistakenly assumed to have
representative outfall status, apparently. Should be corrected by notification
in the transmittal letter and requiring sampling at all outfalls in thepermit.
See item 5.
c. Data for the one outfall was incomplete. Should be corrected
d. The incomplete data exceeded benchmark values. Add new provisions
requiring action in new permit.
e. Sample frequency to be increased from previous 3+4 to 2/yr for 5 yrs.
3. Permit text
a. Note added pH, not in 1999 permit. Appropriate since pH reported outside
benchmark range, and we know from file materials that acids are on site.
(�b. Consider whether being next door to, and intimately associated with, Carolina
ByProducts - a rendering facility- suggests that the imported animal parts
and fats provide a potential source for fecal coliform or other bacteriological
indicators of pollution. Consider adding fecal or alternate bacteriological
® indicator.
c. Given that animal fats are the raw material, I wonder if FOG would be
preferable to O&G. Maybe check with Connie to see if O&G substantially
captures fats. If not, maybe we need help selecting a benchmark for FOG.
d. I concur with quarterly -- continuing exceedances of benchmark values for
BOD and COD, plus pH values suggest more attention and action required.
4. Staff report
a. Concur with adding pH.
b. Concur with new permit requirement to continue sampling upon expiration.
c. Concur with quarterly monitoring, based on the indication that more attention
to the condition of runoff would be beneficial at this site.
d. Concur with retaining the vehicle maintenance section, even though applicant
reports no vehicle maintenance activities currently.
e. Concur with specifying site map contents.
® f. Note production of amids - do we need to test for additional forms of N, other
than just TN? While TN gives us an idea of nutrient contribution, a form like
NH3 would give us a feel for toxicity. Maybe ask BB on this.
g. Concur with conclusion that applicant's has submitted sufficient info to renew
the permit. May need just a little more info/decisions internally to determine
final form for draft permit.
5. Representative outfall status and related issues
a. Note that the text of the 10/27/93 DWQ letter to applicant says in two places -
that the representative status is.for purposes of the initial application, i.e.
prior to issuance of the first permit. There is no indication in the file materials
that DWQ subsequently agreed to carry this status forward into the life of the
permit. On the contrary, the texts of the 12/1/94 permit, the revised 3/8/95
permit, the re -revised 12/19/96 permit, and the 12/1/99 reissued permit all
carry the explicit instruction that each outfall is to be sampled. These were
individual permits, intended to be specifically crafted for the conditions at the
exfcr-D EPA ii 601 +CNe1KCAL + q (_b t�uDVCTS T'"'Tk C� . " l"CMER I.Ecvl�nfhEND N1143

specific permitted site. Why would we continue to require sampling at every
outfall in the permit text, if it was our intent to grant representative status? I
don't think we would. So, I conclude that we never granted representative
outfall status (based on the lack of documentation to that effect, and based
on the repeated permit text.)
b. Note further that the 40CFR citation offered in the 1993 letter is specifically
concerned with the initial application, not the continuing life of the permit.
c. Note that sample results for Outfail 001 have never been submitted to DWQ.
It has been 13+ years since the 1993 letter; facilities can change over that
length of time. Even if, by our inaction, we have inadvertently indicated
agreement with representative outfall status, my opinion is that it is
appropriate for us to revisit that inadvertent result, and require sampling at
all outfalls. If subsequent data (after a couple of years) substantiates a basis
for representative outfall status, we can reconsider, and reduce the
monitoring burden on the permittee.
d. Second, related point: Note that the site plan shows sizable industrial activity
areas not identified as drainage areas. On what basis? Even if these areas
are piped or trenched to the WWTP, they still are stormwater drainage areas,
they still must be shown on the site plan as such. And any surface discharge
from them is another stormwater discharge outfall point unless it totally,
100% positively is conveyed to the WWTP. It seems the permittee needs to
satisfy our concern on the physical facts in these areas of the site.
b. Peer review summary
a. Concur w/ pH, quarterly, site plan requirements, continuation of sampling.
b. Consider adding fecal (or other bact.), NH3, FOG in lieu of O&G.
c. Suggest require sampling at all outfalls, not just #002.
d. Suggest require explanation or revised site plan or recognition of additional
previously unidentified outfalls.

I did revisit the site with City of Greensboro Stormwater staff and the Pretreatment staff. Most issues
were resolved and the remaining items were going to take some more time to complete. There were
some funding issues that needed to be approved through their corporate office. I will be in contact with

referenced in the March 8, 1995 letter.
• March 8, 1995: Letter with redrafted permit for issuance when they withdraw petition. This redrafted
permit removed the requirement to segregate stormwater runoff from the roadway and Chemol site
runoff because the runoff from leaking trucks is on the property of the "neighboring rendering facility
operation". The neighboring facility is permitted separately as Carolina Byproducts (NCG 060131),
though this facility and Chemol are both Divisions of CBP Resources. This letter warns that if runoff

Central Office Review Summary:
This facility discharges to Mile Run Creek in the Cape Fear River Basin in subbasin 03-06-02 (C, NSW). This
stream is not impaired on the draft 2006 303(d) list. The facility is not far upstream (--3/4 mile) from the point
where Mile Run Creek flows to South Buffalo Creek (AU 16-11-14-2a), which is impaired for impaired biological
integrity (1998) and turbidity standard violations (2006). Both the Basinwide plan and the 303(d) list MS4 NPDES
as the source of stress for South Buffalo Creek.
—Following -an-inspection -by-Corey- Basinger -(-Winston- Salem _Regional Office) and -the _Greensboro_ Stormwater—
Department, the permittee was issued a Notice of Deficiency on January 18, 2005. The permittee was given
deadlines to complete five items. All deadlines were within February 2005.
a) Repair cracks in the dyke protecting the acid tanks.
b) Repair the tank high level alarms.
c) Repair the Rail Line sump pump so that the wastewater is properly directed.
d) Label all drums.
e) Determine and label the source of all lines that discharge outside of the dyke structure.
DWQ recommended three additional changes without deadlines, 1.) After the permit is issued the permittee should
update the SPPP, 2.) Label all pipes at the facility, and 3.) Clean out all of the drains at the facility.
The reviewer contacted Corey Basinger (WSRO) and verified that a follow up inspection was conducted. Most of
the items were resolved and the remaining issues were going to take more time as funding was required from their
corporate office. Corey will be in contact with the applicant to follow up, and supports re -issuance of the permit in
accordance with the current Division guidelines.
The permit expired November 30, 2004. No monitoring data has been submitted since expiration.

Qualitative Monitoring Results:
The permittee reports that the water has been consistently clear, and that there have not been any color, foam,
odor, oil sheen or other signs of pollution on the days that they have monitored. However, on November 19, 2003
the lab analysis reports that the BOD5 was more than three times the benchmark, the COD was approximately
twice the benchmark, and the TSS was in excess of the benchmark. Additionally, the pH was highly acidic (4.8)
which is well below the benchmark (6-9). Significant solids, unclarity, and foam would be expected under these
conditions. The permittee reports that this date represented the heaviest rain qualitatively monitored for the
permitted timeframe. Therefore, low (diluted) analytical results would be expected on this date. November 19,
2003 is the only date that both analytical and qualitative monitoring were performed, and is therefore the only date
that such monitoring can be compared. The permittee did not adhere to the monitoring directions on the
qualitative monitoring form requiring the permittee to use numerical estimates for clarity, floating solids, and
suspended solids. The reviewer recommends that the permittee be more diligent when conducting qualitative
monitoring, and submit such monitoring regularly to the Division after each monitoring event using the
methodology set out in the Division's Qualitative Monitoring form. Though it is not required on the Qualitative
Monitoring form, the reviewer recommends that the permittee consider reporting the number of inches of rain as
well as the duration of the rain event for this monitoring. Qualitative monitoring results were not submitted at
regular intervals during the permitted timeframe. It appears from the file that all of these results were submitted
only with the renewal application.
Analytical Monitoring:
1. pH has been added. Though the permittee sampled for pH, it was not required in the previous permit.
- This -was -likely an -oversight -in -the previous permit: ---------------
2. Due to a potential lag time between the expiration of this permit and its renewal, the reviewer has specified
in the permit that the permittee is responsible for all monitoring until the renewal permit is issued. See
Footnote 1 of Tables 1, 4, and 5. This approach is recommended because the applicant has not continued
adequate monitoring since the permit expiration.
3. The flow reporting requirement has been removed from the analytical monitoring requirements per
DWQ revised strategy. (The total rainfall and event duration parameters have been retained.) Instead,
Part II Section A clarifies that the SPPP site map include drainage area for each outfall in acres and
percent impervious area in each drainage area (should flow ever need to be estimated.)
4. Benchmarks have been added to this draft permit. These benchmarks are not permit limits but should be
used as guidelines for the facility's Stormwater Pollution Prevention Plan (SPPP). New language specifies
that if any measurements exceed benchmark values, the facility should evaluate the effectiveness of its
BMPs, review and/or update its SPPP, and document any efforts to address stormwater contamination.
See Part II, Sections B & D.
5. All monitoring has been changed to quarterly. The Division has altered its policy since the previous
permit where annual monitoring in years 1,2, and 3 and quarterly monitoring in year 4 was required. The
Division now typically requires semi-annual monitoring for all years. This permittee will have to monitor
quarterly (more often than the typical Division policy) in response to poor analytical monitoring results
during the previous cycle. This permittee did not submit all of the required samples for pH and TN in the
previous cycle. Of those submitted, pH was below the benchmark in 80% of the samples, and TN was over
the benchmark in 25% of the samples. Additionally, of the seven required samples submitted during the
previous cycle for the remaining parameters, the permittee exceeded each parameter in the following
percentages of the samples; oil and grease, 14%; BOD5, 43%; COD, 57%; TSS 14%; and TP, 0%.
6. Vehicle maintenance is not done onsite. However, should the facility begin these operations, they will
have to sample quarterly. This time was chosen to be in line with the other analytical and qualitative
monitoring.
7. There have been three significant operational changes:
a. Removal of a 92,000 gallon vegetable oil tank from service (tank BV-1) -
b. Installation of a new ester tank farm of three storage tanks to store non -hazardous finished
products (contained)
5

NCS000048
c. Enhancement of the plant's secondary containment system and process sewer system
8. Part II Section A has been revised. It now specifies all of the items to include on the site map.
9. Total phosphorus levels have been low over the past several years, but this requirement has not been
removed because this facility drains to NSW waters.
10. This applicant has been sampling at one outfali, though there are two outfalIs noted on the site plan. On
October 27, 1993 the Division granted the applicant permission to sample at only one of these outfalls in
order to collect samples prior to their first stormwater permit. However, there is no documentation in the
file that the applicant was granted permission to continue sampling only one location during the permitting
cycles to come. This is likely a misunderstanding. However, a site visit is recommended to determine how
many outfalls exist at the facility in order to correct this misunderstanding for the upcoming cycle. See the
Recommendations section.
Follow-up with the company contact (Mark Heimberger/336.333.3071/January 8, 2007 & January 26, 2007)
1. Your company was issued a Notice of Deficiency on 18 January 2005. Our file does not contain further
correspondence from you. Have you addressed the concerns set forth in this letter? (On 23 January 2007, C.
Basinger said that there was a follow up inspection. However, documentation is not in the SPU or Central
files.)
Mr. Heimberger faxed over a copy of two letters that he sent us in response to this issue (they were
evidently improperly filed at DWQ). Status of his response to deficient issues:

2. Do you conduct vehicle maintenance at your facility? If so, how many gallons of new motor oil do you
produce each month? (A 55-gallon average will require vehicle maintenance monitoring.)
No.
3. What does your facility manufacture? From your website I believe that you manufacture textile processing
chemicals.
They manufacture waxes and hydrogenated fats and oils. They also react fatty acids with alcohols to
make esters, and also produce amides.
Note about information from applicant: Amides are organic, and contain the chemical group—CONHZ.
They are water-soluble, and most are solid at room temperature.

NCS000048
4. Your company name is "The Seydel Companies". How is this company related to Carolina ByProducts
and/or CBP Resources?
In the early 1990s, both Chemol and Carolina Byproducts (CBP) were Divisions of CBP Resources. In
approximately 1996, Chemol was sold to the Seydel Companies. Chemol is still next door to Carolina
ByProducts, but is not associated with them in any way. They do not share raw materials or products with
one another. Actually, Carolina ByProducts is no longer a manufacturing operation. It is only a transfer
operation where "animal parts" are taken from small trucks and put onto larger trucks.
Recommendation: Based on the documents reviewed, the application information submitted on June 2, 2004 is
sufficient to issue an Individual Stormwater Permit. A site visit is recommended for this facility. Because the
applicant did not submit the appropriate materials at the time of the application, and also failed to submit them
when they were requested in December of 2004 the following questions are recommended to be asked onsite:
1. Determine the appropriate number of outfalls onsite:
a. The applicant was granted permission to sample a single outfall when collecting samples for the initial
permit application. However, there is no evidence in the file that representative outfall status was
granted for the permitting cycle.
b. Two outfalls are noted on the site map. Note the drainage areas for each outfall. Why is there area
that is unaccounted for on this map?

Central Office Review Summary:
This facility discharges to Mile Run Creek in the Cape Fear River Basin in subbasin 03-06-02 (C, NSW). This
stream is not impaired on the draft 2006 303(d) list. The facility is not far upstream (--3/4 mile) from the point
where Mile Run Creek flows to South Buffalo Creek (AU 16-11-14-2a), which is impaired for impaired biological
integrity (1998) and turbidity standard violations (2006). Both the Basinwide plan and the 303(d) list MS4 NPDES
as the source of stress for South Buffalo Creek.
Following an.inspection by Corey Basinger_(Winston_Salem_Regional Office)-and_the Greensboro_Stormwater__ ._
Department, the permittee was issued a Notice of Deficiency on January 18, 2005. The permittee was given
deadlines to complete five items. All deadlines were within February 2005.
a) Repair cracks in the dyke protecting the acid tanks.
b) Repair the tank high level alarms.
c) Repair the Rail Line sump pump so that the wastewater is properly directed.
d) Label all drums.
e) Determine and label the source of all lines that discharge outside of the dyke structure.
DWQ recommended three additional changes without deadlines, 1.) After the permit is issued the permittee should
update the SPPP, 2.) Label all pipes at the facility, and 3.) CIean out all of the drains at the facility.
The reviewer contacted Corey Basinger (WSRO) and verified that a follow up inspection was conducted. Most of
the items were resolved and the remaining issues were going to take more time as funding was required from their
corporate office. Corey will be in contact with the applicant to follow up, and supports re -issuance of the permit in
accordance with the current Division guidelines.
The permit expired November 30, 2004. No monitoring data has been submitted since expiration.

Data not submitted -

Qualitative Monitoring Results:
The permittee reports that the water has been consistently clear, and that there have not been any color, foam,
odor, oil sheen or other signs of pollution on the days that they have monitored. However, on November 19, 2003
the lab analysis reports that the BODS was more than three times the benchmark, the COD was approximately
twice the benchmark, and the TSS was in excess of the benchmark. Additionally, the pH was highly acidic (4.8)
which is well below the benchmark (6-9). Significant solids, unclarity, and foam would be expected under these
conditions. The permittee reports that this date represented the heaviest rain qualitatively monitored for the
permitted timeframe. Therefore, low (diluted) analytical results would be expected on this date. November 19,
2003 is the only date that both analytical and qualitative monitoring were performed, and is therefore the only date
that such monitoring can be compared. The permittee did not adhere to the monitoring directions on the
qualitative monitoring form requiring the permittee to use numerical estimates for clarity, floating solids, and
suspended solids. The reviewer recommends that the permittee be more diligent when conducting qualitative
monitoring, and submit such monitoring regularly to the Division after each monitoring event using the
methodology set out in the Division's Qualitative Monitoring form. Though it is not required on the Qualitative
Monitoring form, the reviewer recommends that the permittee consider reporting the number of inches of rain as
well as the duration of the rain event for this monitoring. Qualitative monitoring results were not submitted at
regular intervals during the permitted timeframe. It appears from the file that all of these results were submitted
only with the renewal application.
Analytical Monitoring:
1. pH has been added. Though the permittee sampled for pH, it was not required in the previous permit.
This was likely_an.oversight in.the.previous .permit.
2. Due to a potential lag time between the expiration of this permit and its renewal, the reviewer has specified
in the permit that the permittee is responsible for all monitoring until the renewal permit is issued. See
Footnote 1 of Tables 1, 4, and 5. This approach is recommended because the applicant has not continued
adequate monitoring since the permit expiration.
3. The flow reporting requirement has been removed from the analytical monitoring requirements per
DWQ revised strategy. (The total rainfall and event duration parameters have been retained.) Instead,
Part II Section A clarifies that the SPPP site map include drainage area for each outfall in acres and
percent impervious area in each drainage area (should flow ever need to be estimated.)
4. Benchmarks have been added to this draft permit. These benchmarks are not permit limits but should be
used as guidelines for the facility's Stormwater Pollution Prevention Plan (SPPP). New language specifies
that if any measurements exceed benchmark values, the facility should evaluate the effectiveness of its
BMPs, review and/or update its SPPP, and document any efforts to address stormwater contamination.
See Part II, Sections B & D.
5. All monitoring has been changed to quarterly. The Division has altered its policy since the previous
permit where annual monitoring in years 1,2, and 3 and quarterly monitoring in year 4 was required. The
Division now typically requires semi-annual monitoring for all years. This permittee will have to monitor
quarterly (more often than the typical Division policy) in response to poor analytical monitoring results
during the previous cycle. This permittee did not submit all of the required samples for pH and TN in the
previous cycle. Of those submitted, pH was below the benchmark in 80% of the samples, and TN was over
the benchmark in 25% of the samples. Additionally, of the seven required samples submitted during the
previous cycle for the remaining parameters, the permittee exceeded each parameter in the following
percentages of the samples; oil and grease, 14%; BODSi 43%; COD, 57%; TSS 14%; and TP, 0%.
6. Vehicle maintenance is not done onsite. However, should the facility begin these operations, they will
have to sample quarterly. This time was chosen to be in line with the other analytical and qualitative
monitoring.
7. There have been three significant operational changes:
a. Removal of a 92,000 gallon vegetable oil tank from service (tank BV-1)
b. Installation of a new ester tank farm of three storage tanks to store non -hazardous finished
products (contained)

NCS000048
c. Enhancement of the plant's secondary containment system and process sewer system
8. Part II Section A has been revised. It now specifies all of the items to include on the site map.
9. Total phosphorus levels have been low over the past several years, but this requirement has not been
removed because this facility drains to NSW waters.
10. This applicant has been sampling at one outfall, though there are two outfalls noted on the site plan. On
October 27, 1993 the Division granted the applicant permission to sample at only one of these outfalls in
order to collect samples prior to their first stormwater permit. However, there is no documentation in the
file that the applicant was granted permission to continue sampling only one location during the permitting
cycles to come. This is likely a misunderstanding. However, a site visit is recommended to determine how
many outfalls exist at the facility in order to correct this misunderstanding for the upcoming cycle. See the
Recommendations section.
Follow-up with the company contact (Mark Heimberger/336.333.3071/January 8, 2007 & January 26, 2007)
1. Your company was issued a Notice of Deficiency on 18 January 2005. Our file does not contain further
correspondence from you. Have you addressed the concerns set forth in this letter? (On 23 January 2007, C.
Basinger said that there was a follow up inspection. However, documentation is not in the SPU or Central
files.)
Mr. Heimberger faxed over a copy of two letters that he sent us in response to this issue (they were
evidently improperly filed at DWQ). Status of his response to deficient issues:

2. Do you conduct vehicle maintenance at your facility? If so, how many gallons of new motor oil do you
produce each month? (A 55-gallon average will require vehicle maintenance monitoring.)
No.
3. What does your facility manufacture?, From your website I believe that you manufacture textile processing
chemicals.
They manufacture waxes and hydrogenated fats and oils. They also react fatty acids with alcohols to
make esters, and also produce amides.
Note about information from applicant: Amides are organic, and contain the chemical group--CONH2.
They are water-soluble, and most are solid at room temperature.

NCS000048
4. Your company name is "The Seydel Companies". How is this company related to Carolina ByProducts
and/or CBP Resources?
In the early 1990s, both Chemol and Carolina Byproducts (CBP) were Divisions of CBP Resources. In
approximately 1996, Chemol was sold to the Seydel Companies. Chemol is still next door to Carolina
ByProducts, but is not associated with them in any way. They do not share raw materials or products with
one another. Actually, Carolina ByProducts is no longer a manufacturing operation. It is only a transfer
operation where "animal parts" are taken from small trucks and put onto larger trucks.
Recommendation: Based on the documents reviewed, the application information submitted on June 2, 2004 is
sufficient to issue an Individual Stormwater Permit. A site visit is recommended for this facility. Because the
applicant did not submit the appropriate materials at the time of the application, and also failed to submit them
when they were requested in December of 2004 the following questions are recommended to be asked onsite:
1. Determine the appropriate number of outfalls onsite:
a. The applicant was granted permission to sample a single outfall when collecting samples for the initial
permit application. However, there is no evidence in the file that representative outfall status was
granted for the permitting cycle.
b. Two outfalls are noted on the site map. Note the drainage areas for each outfall. Why is there area
that is unaccounted for on this map?

SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. This Plan shall be considered public information in accordance with Part I11, Standard
Conditions, Section E, Paragraph 3 of this individual permit. The Plan shall include, at a
minimum, the following items:
Site Plan. The site plan shall provide a description of the physical facility and the
potential pollutant sources which may be expected to contribute to contamination of
stormwater discharges. The site plan shall contain the, following':
a. A general location map (USGS quadrangle map or appropriately drafted
equivalent map), showing the facility's locati6❑ in relation to transportation
routes and surface waters, the narrne.of the receiving water(s) to which the
stormwater outfall(s) discharges, or;if the discharge is to a municipal separate
storm sewer system, the name4of ttie municipality and the ultimate receiving
waters; and accurate latitude anddl�oongitude of the point(s) of discharge.
b. A narrative description of storage practices, loading and unloading activities,
outdoor process areas dust•or particulate generating or control processes, and
waste disposal practices,
A site map drawn to�kale with the following items:
(1) Dista`nce legend and north arrow
(2) Location of industrial activities (including storage of materials,
disposal areas, process areas and loading and unloading areas)
(3) Drainage structures
(4) Delineated drainage areas for each outfall
(5) Drainage area for each outfall in acres and percentage of
each drainage area that is impervious
(6) Building locations
(7) Existing BMPs and impervious surfaces
(8) For each outfall, a narrative description of the potential pollutants that
could be expected to be present in the stormwater discharge.
d. A list of significant spills or leaks of pollutants that have occurred at the facility
during the 3 previous years and any corrective actions taken to mitigate spill
impacts.
e. Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The certification statement will be signed in
accordance with the requirements found in Part III, Standard Conditions, Section
B, Paragraph 3.
Part I1 Pa-e I of 8

Permit No. NCS000048
2. Stormwater Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following:
a. Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. Wherever practical, the permittee shall
prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations. In areas where elimination of exposure is
not practical, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
b. Secondary Containment Schedule. A schedule to provide secondary containment
for bulk storage of liquid materials, storage of,Section 313 of Title III of the
Superfund Amendments and Reauthorization Act (SARA) water priority
chemicals, or storage of hazardous substances to prevent leaks and spills from
contaminating stormwater runoff fIf, th f,secondary containment devices are
connected directly to sto-nwater,,co veyance systems, the connection shall be
controlled by manually activated valves or other similar devices [which shall be
secured with a locking`mechanism] and any stormwater that accumulates in the
containment area shall,be at a,minimum visually observed for color, foam, outfall
staining, visible sheens and dry weather flow, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated`by_the material stored within the containment area. Records
documenting the -individual making the observation, the description of the
accumulated stormwater and the date and time of the release shall be kept for a
period of five years.
BMP Summary. A narrative description shall be provided of Best Management
Practices (BMPs) to be considered such as, but not limited to, oil and grease
separation, debris control, vegetative filter strips, infiltration and stormwater
detention or retention, where necessary. The need for structural BMPs shall be
based on the assessment of potential -of sources to contribute significant quantities
of pollutants to stormwater discharges and data collected through- monitoring of
stormwater discharges.
3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or team) responsible for implementing the
SPRP shall be identified.' A responsible person shall be on -site at all times during facility
operations that have the potential to contaminate stormwater runoff through spills or
exposure of materials associated with the facility operations. The SPRP must be site
stormwater specific. Therefore, a SPCC plan may be a component of the SPRP, but may
Part 11 Page 2 of 8

Permit No. NCS000048
not be sufficient to completely address the stormwater aspects of the SPRP. The common
elements of the SPCC with the SPRP may be incorporated by reference into the SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance program shall be developed. The program shall document schedules of
inspections and maintenance activities of stormwater control systems, plant equipment
and systems. Inspection of material handling areas and regular cleaning schedules of
these areas shall be incorporated into the program.
5. Employee Training. Training schedules shall be developed and training provided at a
minimum on an annual basis on proper spill response and cleanup procedures and
preventative maintenance activities for all personnel involved in any of the facility's
operations that have the potential to contaminate stormwater runoff. Facility personnel

Item 4: Best Management Practices
A. SECONDARY CONTAINMENT SYSTEMS
All of the processing areas, above ground storage tanks, loading/unloading areas, and the
Flammable Drum Storage Area have secondary containment. The specifics of each containment
area are addressed below:
A.I. Main Plant Area
All of the above ground storage tanks in the main plant are located in a common
secondary containment area with the exception of Tank 5-28. The secondary containment for the
main plant is created through the use of concrete walls/curbs, concrete floors and
asphalt/concrete aprons sloped toward the interior of the main plant. These walls/curbs and
sloped aprons provide containment for the entire main plant. Based on an instrument survey of
the main plant, the containment volume is estimated to be approximately 113,800 gallons. Note
the largest single tank capacity in the main plant is 30,000 gallons (Tank 5-31).
Normally, any spilled liquid is collected in the trench drains located throughout the main
plant and conveyed by gravity to the sewer lift station located in the southeast quadrant of the
main plant's containment area. Rainwater that enters the secondary containment area is also
collected in the trench drains, and conveyed to the sewer lift station and the pretreatment system
before entering the sanitary sewer system. The majority of the rainwater that falls on the main
plant is captured by roof drains and discharged outside of the secondary containment area.
The only tank in the main plat area that is not contained in the common secondary .
containment area is 5-28, which is a 5,000-gallon acid tank. Tank 5-28 has a separate concrete
secondary containment area. This containment area is adequately sized to contain a release of the
full contents of tank 5-28 (plus 10%), plus precipitation. Storm water is released from this area
via pumping into the main plant's process sewer system.
A.2. Main Tank Farm Area
All of the tanks in the tank farm area are located in a common secondary containment
area. The secondary containment area is constructed of concrete floors and walls. This
containment area is adequately sized to contain a release of the full contents of the largest tank
(plus 10%), plus precipitation. No drains are located in this secondary containment area. The
secondary containment area for these tanks is equipped with a sump and pump to remove
rainwater and spilled materials. All spilled material or rainwater is pumped to the Main Plant's
process sewer system.

A.3. Ester Tank Farm
All the tanks in the Ester Tank Farm are located in a common secondary containment
area. The secondary containment area is constructed of concrete floors and walls. This
containment area is adequately sized to contain a release of the largest tank (plus 10%), plus
precipitation. The transfer pump for the tanks in this area is located within the secondary
containment structure. No drains are located in the secondary containment structure. Rainwater
and spilled materials are removed via a sump pump that discharges into the Main Plant's process
sewer system..
A.4. Rail Car Loading/Unloading Area
The rail car tank transfer station (next to the Main Tank Farm) is designed with a
secondary containment system to prevent leaks and drips from the rail cars from entering the
environment. However, the containment area is unable to control a major release that could
occur from a faulty valve or full tank car failure nor hold the contents of the largest capacity rail
car (23,000 gallons maximum) that services the area. The secondary containment pad, located
partly beneath the rail tank car being loaded/unloaded, is concrete and slopes toward a sump
located adjacent to the tracks. The transfer connection (valves) on the railcar is centered over the
concrete pad during transfer operations so that should a spill occur at the valve, it would drain to
the sump. The sump is provided with a pump to transfer the spilled material into the Main
Plant's process sewer system.
A.S. Alcohol Tank Farm
All the tanks in the Alcohol Tank Farm are located in a common secondary containment area.
The secondary containment area is -constructed of concrete floors and walls. The containment
area is sufficiently sized to contain the required 110 percent of the largest tank located within it
plus precipitation. The transfer pumps for the tanks in this area are located within the secondary
containment structure. The secondary containment area is equipped with a sump and pump to
remove rainwater and spilled materials. No drains are located in the secondary containment area
for the tanks. All spilled material or rainwater is pumped to the Main Plant's process sewer
system.
A.6. Flammable Drum Storage Area
The Flammable Drum Storage Area is a concrete storage area surrounded by a b=foot high chain -
link fence. --A sloped concrete ramp provided access for .forklifts to enter and exit the secondary
contairunent area. The area is -approximately 42-feet long by-12 feet wide, grid"has a 6-inch high
concrete secondary containment curb. Based on an available containment depth of 4 inches
(because the drums are placed on 4 inch pallets), the secondary containment area holds
approximately 1240 gallons. This is equivalent to approximately twenty-two 55-gallon drums.
Since the largest "tank" is a single portable tote tank with a nominal.300-gallon capacity, the
Flammable Drum Storage Area is adequately designed to contain a release of the largest vessel
plus precipitation.
Storm water or spills from inside this secondary containment area flow to a sump and are
pumped to the Main Plant's process sewer system.

A.7. Inspection of Secondary Containment Systems
The facility's secondary containment systems -are formally inspected weekly: The
inspection includes examination of the containment structure's integrity. Any potoatial failure
points in the containment structures are repaired. The Environmental Manager maintains
completed forms
B. BULK STORAGE TANK INSPECTION AND INVENTORY CONTROL'
Inventory levels of bulk tanks are generally taken three times per week. Personnel
performing the inventory examine the tanks and report any suspected leaks. Further, the
inventory is compared with the previous inventory and any abnormal changes are investigated.
C. FACILITY TRANSFER OPERATIONS, PUMPING, AND IN -PLANT PROCESS
All in -plant transfers are manned operations. All transfer pumps in the main plant are visible and
are monitored during transfer operations. The transfer pumps for the Main Tank Farm, Alcohol
Tank Farm, and Ester Tank Farm are located within the secondary containment area for the
respective tank farm. To determine if liquids can be -transferred between tanks, personnel
measure the receiving tank and verify the transferred material will fit.
All transfer piping at the facility is either exposed (above ground) for visual inspection or is
contained in a steel plate fabricated pipe trench (top of trench is parallel with existing grade).
Normal vehicular traffic does not pose a direct threat to above ground piping.
D. FACILITY TANK CAR AND TANK TRUCK LOADINGIUNLOADING
Transfers of materials to and from outside sources (tank wagons and railcars) occur:at two
locations at the Chemol facility;
I) Tank trucks load and unload to the west of the main plant and
2) Rail cars park in the rail car unloading area located west of the main tank farm..
D.I. Railcar Unloading
The rail car unloading area has a single_ connection point for unloading operations; which
precludes the -opportunity for confision in piping. -The rail car -unloading area services -tanks in� -
the tank farm area (TF-1 through TF-7), which are equipped with local audible high-level alarms.
The rail unloading area is designed with a secondary containment system to prevent leaks and
drips from the rail cars from entering the environment; however, the containment area is unable
to control a major release occurring from a faulty valve or full tank car failure. Currently,
railcars are only used to receive non -hazardous raw materials that are solid at ambient
temperatures. They are only heated when the railcar is positioned over the containment structure.
This precludes the possibility material could leak from a railcar not positioned over the
containment structure. See Section AA for additional information on the secondary containment
at this location.

D.2. Tank Truck Loading and Unloading
The taiilc truck loading/unloading area is -located west of the main plant within the
secondary containment of the main plant. Like the tanks in the main plant, all of the leaks, drips
and spills are collected in the trench drains and processed within the wastewater pretreatment
system. Piping locations for loading and unloading operations in this area are labeled to indicate
their respective discharge locations.
The surface of the tank truck loading/unloading area is concrete. This surface is
periodically washed to minimize the tracking of chemicals outside of the containment structure
by tank wagons or forklift tires.
D.3. Monitoring of Transfer Operations and Equipment
All transfer operations are monitored by personnel throughout the transfer. Further, plant
personnel inspect any hoses, connection fittings, piping and pumps prior to starting the transfer
and during the transfer.
E. SECURITY
Security is controlled by plant personnel being on -site 24 hours a day when the plant is operating.
When the plant is not operating, security personnel are on -site. Security personnel use a punch
card and monitoring panel system to ensure frequent visits to all tank storage areas. Part of the
security personnel's responsibilities includes at least bi-hourly visits to each of the monitoring
panels. Monitoring panels are located at each tank farm area and at multiple locations within the
main plant.
Lighting is sufficient throughout the facility to allow detection of a spill at night.
F. SPILL PREVENTION AND MITIGATION PROCEDURES
F.I. Spills Outside of Containment Structures
Employees are required to immediately clean up any spill or leaks outside of containment
- st uctures: -Ally swill -[hat occi=trs outsid"e of a containarierit-structuie'tllat-cariffot'be controlled -is
immediately reported to emergency agencies by dialing 911. Further Che_mol will contract the
services of Sliamfock Environmental to provide -emergency remediation and response:
F.2. Spills Inside of Containment Structures
Spill of material inside of containment structures are either recovered for reuse or placed
into the plant's process sewer system. The actions taken are appropriate for the amount of
material spilled and its hazard level.
F.3. Training
All employees who work in the processing area are trained in the operation of equipment to
prevent discharges of process chemical into storm water. This training is held in conjunction

with Spill Prevention, Control and Countermeasure (SPCC) Training and includes a discussion
of material transfer and acceptance procedures, and applicable laws, rules and regulations. A
knowledgeable person provides this training with experience in spill response, contr'in2nent and
control. Training is conducted at least once per year for these personnel.
During the training session, a -briefing is held to assure adequate understanding of the SPCC Plan
and Stormwater Pollution Prevention (SPP) Plan. These briefings also highlight recent spill
events, failures, and precautionary measures. Records of employee training sessions are
maintained with the SPCC Plan and are kept for at least three years.
Additional annual training on uncontrolled spills occurs as part of the Emergency Action Plan
Training Program. Records of this training are maintained.
G. Waste Streams and Handling
G.1. Plant Process Sewer Liquid Waste
All rainwater and residual chemicals collected in any of the tank farms or production
areas enter the plant's sewer system. The materials are acidified to separate any oil layer from
the water layer. The water layer is separated, neutralized and discharged to the City of
Greensboro's Sanitary Sewer System. The grease layer is sold as a non -hazardous by-product
stream.
G.2. Solid Waste from Production, Warehouse, Maintenance, Laboratory and Office
Operations
Chemol's operations generate non -hazardous solid wastes that are sent to a licensed
landfill. The solid wastes are placed in one of two "rolloff" containers. One of these containers
is within the plant's containment structure. Any runoff of rainwater from this container would go
into the main plant's containment structure.
The second solid waste dumpster is placed over a collection sump which collects any
rainwater ninoff. Any runoff is then pumped into the main plant's process sewer.
G.3. Laboratory Hazardous Waste
l _
_ Chemol's laboratory operations generate small quantities of hazardous waste. This waste
= is.removed.by licensed hazardous waste liauIeis and incinerated: _Reco_rds; of waste generated ariii l
its associated disposal are maintained.
H. Preventive Maintenance
ChemoI has a preventive maintenance program involving scheduled maintenance on all
equipment. This program is currently being updated to enhance its effectiveness and formal
documentation. Further, Chemol has a work order system to repair any unplanned equipment
failures. Any maintenance activity required to address potential or actual stormwater
contamination is considered a high priority relative to other maintenance activities.

1. Pallet Storage
Chemol stores a variety of wooden pallets in uncontained areas. The large majority of
these pallets are new and do not pose a potential to contaminate stormwater. A small number of
pallets (averaging below 50) have been used in the production area and could be contaminated
with small quantities of non -hazardous materials. Runoff from these pallets could potentially
contaminate stormwater. Currently, all used pallets are removed from the site by a pallet
recycler. Chemol plans to upgrade its handling of used pallets to minimize the potential for
stormwater contamination. Options being consider include, but are not limited to, placing a roof
over the storage area or disposing of contaminated pallets in the current "rollof " containers
described in Section G.2.

Item S: Significant Changes in Industrial Activity at the Permitted Facility
There have been three significant changes in activities since the last permit renewal application:
Change 41: Removal of the Vegetable Oil Tank (BV-1) from Service
This 92,000-gallon tank has been taken out of service. This will eliminate any potential
stormwater contamination resulting from the failure of this tank or its associated components.
Change 92: Installation of the Ester Tank Farm and associated tanks
A new tank farm with three storage tanks was installed. This tank farm is utilized to store
non -hazardous finished products. This tank farm is contained and any stormwater or other
material within the contaitunent structure is pumped to the plant's process sewer. Further details
on this tank farm are listed under Item 4: Best Management Practices, Section A.3.
Change #3: Enhancement of Main Plant's Secondary Containment System and Process
Sewer System
The Main Plant's containment system has been enhanced by incorporating the existing
cooling tower within it boundaries. This precludes the possibility of excessive cooling tower
overflows from entering stormwater runoff.
Moving the process sewer lift pumps to within the Main Plant's secondary containment
structure has enhanced the Process Sewer System. Previously, these pumps were located outside
of the containment structure and adjacent to the sanitary sewer outfail. A lift pump failure could
have caused a discharge of untreated wastewater into the Sanitary Sewer. Further, any failure of
the pipes running to or from the lift pumps in the old location could have caused stormwater
cortaminaton Moving the -lift- pumps- minimized=the_possibility, of_ discharging_untreated_.

Division of Water Quality
On Thursday, January 13, 2005, Corey Basinger with the Division of Water Quality visited the subject facility
located off Randolph Avenue in Greensboro, NC. Ray Boettcher, William Newlin and Peter Sneider (Greensboro
Stormwater Department) were also present during the inspection. The purpose of this inspection was to determine
whether or not the subject facility was in compliance with NPDES Stormwater Permit No. NCS000048. During this
site visit, the following deficiencies were documented.
1) The dyke wall protecting the acid tanks had significant cracking on both of the outside corners. The dyke
structure must be repaired immediately to prevent the release of any materials that might accumulate
inside the structure. The repairs must be completed no later than February 11, 2005. You are
required to notify this Office when the repairs are completed.
2) The alarm system was not operating properly at the time of inspection. The visual and audible alarms did
function, but not in response to high levels in the tanks. The alarms must be repaired immediately. It is
highly recommended that the alarms have a manual "test" feature so that they can be tested on a routine
basis. The alarms must be properly operational no later than February 11, 2005. You are required to
notify this Office when the alarms are properly operational.
3) The Rail Line sump pump system was not operating properly. The containment structure was full and
beginning to overflow at the time of inspection. It was reset and began pumping the wastewater back up
to the plant site. The wastewater is actually pumped out onto the paved area at the truck
loading/unloading area and drains into the dyke structure, which empties into the wastewater collection
system. This process should be modified such that the wastewater is pumped directly into the wastewater
collection system or piped away from the truck loading/unloading area in order to prevent the truck tires
from carrying any wastewater out of the dyke area. The sump pump system must be repaired/modifred
no later than February 18, 2005.
4) All drums located at the facility must be properly labeled. The drums must also the segregated based on
their contents. If available, a Material Safety Data Sheet (MSDS) must be kept on file at the facility and
made readily available to staff and/or emergency personnel. The drums located in the fenced area
marked "flammable" should be arranged such that the drums placed on pallets are more toward the center
of the containment area to prevent spillage outside the dyke as result of a puncture/rupture. All drums
must be labeled, segregated, and have the appropriate MSDS no later than February 25, 2005.

S) The source of all pipes that discharge outside the dyke structure must be determined and properly labeled
(ie: roof drain). If no source can be determined, the pipe must be permanently capped. Also, the old
sanitary line and clean out pipe must be permanently capped to prevent accidental discharge to the
sanitary sewer. This must be completed no later than February 25, 2005.
6) Once the permit is reissued, the Stormwater Pollution_ Prevention Plan documentation should be updated
to reflect any changes or. modifications.
7) It is recommended that all exposed piping at the facility be color coded or labeled such that it is clear
what materials are flowing through each pipe and which direction the materials are flowing in the pipe.
8) It is recommended that all drains at the facility be cleaned out to allow for maximum flow. The material
removed from the drains must be disposed of properly.
This Office will schedule a follow-up inspection in early March 2005 to ensure that the required corrected actions
are completed. Should you have questions or comments regarding this correspondence, please contact Corey
Basinger at [phone] x-288.

Your facility is currently covered for stormwater discharge under NPDES Permit NCS000048. This permit expires
on November 30, 2004. North Carolina Administrative Code (15A NCAC 2H.0105(e)) requires that an
application for permit renewal be tiled at least I80 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 June 3, 2004 in order for the permit to be renewed by November 30, 2004.
Failure to request renewal by June 3.2004 may result in a civil assessment of at least $500.00. Larger penalties
may be assessed depending on the delinquency of the request. Discharge of stormwater from your facility without
coverage under a valid stormwater NPDES permit would constitute a violation of NCGS 143-215.1 and could
result in assessments of civil penalties of up to $25.000 per day.
If you have any questions regarding the permit renewal procedures please contact Bill Mills of the Stormwater and

Item 4: Best Management Practices
A. SECONDARY CONTAINMENT SYSTEMS
All of the processing areas, above ground storage tanks, loading/unloading areas, and the
Flammable Drum Storage Area have secondary containment. The specifics of each containment
area are addressed below:
A.I. Main Plant Area
All of the above ground storage tanks in the main plant are located in a common
secondary containment area with the exception of Tank S-28. The secondary containment for the
main plant is created through the use of concrete walls/curbs, concrete floors and
asphalt/conerete aprons sloped toward the interior of the main plant. These walls/curbs and
sloped aprons provide containment for the entire main plant. Based on an instrument survey of
the main plant, the containment volume is estimated to be approximately 113,800 gallons. Note
the largest single tank capacity in the main plant is 30,000 gallons (Tank S-31).
Norirrally, any spilled liquid is collected in the trench drains located throughout the main
plant and conveyed by gravity to the sewer lift station located in the southeast quadrant of the
main plants containment area. Rainwater that enters the secondary containment area is also
collected in the trench drains, and conveyed to the sewer lift station and the pretreatment system
before entering the sanitary sewer system. The majority of the rainwater that falls on the main
plant is captured by roof drains and discharged outside of the secondary containment area.
The only tank in the main plat area that is not contained in the common secondary
containment area is S-28, which is a 5,000-gallon acid tank. Tank S-28 has a separate concrete
secondary containment area. This containment area is adequately sized to contain a release of the
full contents of tank S-28 (plus 10%), plus precipitation. Storm water is released from this area
via pumping into the main plant's process sewer system.
A.2. Main Tank Farm Area
All of the tanks in the tank farm area are located in a common secondary containment
area. The secondary containment area is constructed of concrete floors and walls. This
containment area is adequately sized to contain a release of the full contents of the largest tank
(plus 10%), plus precipitation. No drains are located in this secondary containment area. The
secondary containment area for these tanks is equipped with a sump and pump to remove
rainwater and spilled materials. All spilled material or rainwater is pumped to the Main Plant's
process sewer system.

A.3. Ester Tank Farm
All the tanks in the Ester Tank Farm are located in a common secondary contaimnent
area. The secondary containment area is constructed of concrete floors and walls. This
containment area is adequately sized to contain a release of the largest tank (plus 10%), plus
precipitation. The transfer pump for the tanks in this area is located within the secondary
containment structure. No drains are located in the secondary containment structure. Rainwater
and spilled materials are removed via a sump pump that discharges into the Main Plant's process
sewer system.
A.4. Rail Car Loading/Unloading Area
The rail car tank transfer station (next to the Main Tank Farm) is designed with a
secondary containment system to prevent leaks and drips from the rail cars from entering the
environment. However, the containment area is unable to control a major release that could
occur from a faulty valve or full tank car failure nor hold the contents of the largest capacity rail
car (23,000 gallons maximum) that services the area. The secondary containment pad, located
partly beneath the rail tank car being loaded/unloaded, is concrete and slopes toward a sump
located adjacent to the tracks. The transfer connection (valves) on the railcar is centered over the
concrete pad during transfer operations so that should a spill occur at the valve, it would drain to
the sump. The sump is provided with a pump to transfer the spilled material into the Main
Plant's process sewer system.
A.5. Alcohol Tank Farm
All the tanks in the Alcohol Tank Farm are located in a common secondary containment area.
The secondary containment area is constructed of concrete floors and walls. The containment
area is sufficiently sized to contain the required 110 percent of the largest tank located within it
plus precipitation. The transfer pumps for the tanks in this area are located within the secondary
containment su_ucture. The secondary containment area is equipped with a sump and pump to
remove rainwater and spilled materials. No drains are located in the secondary containment area
for the tanks. All spilled material or rainwater is pumped to the Main Plant's process sewer
system.
A.6. Flammable Drum Storage Area
The Flammable Drum Storage Area is a concrete storage area surrounded by a 6-foot high chain -
link fence. A sloped concrete ramp provided access for forklifts to enter and exit the secondary
containment area. The area is approximately 42 feet long by 12 feet wide, and has a 6-inch high
concrete secondary containment curb. Based on an available contaimnent depth of 4 inches
(because the drums are placed on 4 inch pallets), the secondary contaimnent area holds
approximately 1240 gallons. This is equivalent to approximately twenty-two 55-gallon drums.
Since the largest "tank" is a single portable tote tank with a nominal 300-gallon capacity, the
Flammable Drum Storage Area is adequately designed to contain a release of the largest vessel
plus precipitation.
Storm water or spills from inside this secondary containment area flow to a sump and are
pumped to the Main Plant's process sewer system.

A.7. Inspection of Secondary Containment Systems
The facility's secondary containment systems are formally inspected weekly; The
inspection includes examination of the containment structure's integrity. Any poteaatial failure
points in the containment structures are repaired. The Environmental Manager maintains
completed forms
B. BULK STORAGE TANK INSPECTION AND INVENTORY CONTROL'
Inventory levels of bulk tanks are generally taken three times per week. Personnel
performing the inventory examine the tanks and report any suspected leaks. Further', the
inventory is compared with the previous inventory and any abnormal changes are investigated.
C. FACILITY TRANSFER OPERATIONS, PUMPING, AND IN -PLANT PROCESS
All in -plant transfers are manned operations. All transfer pumps in the main plant are visible and
are monitored during transfer operations. The transfer pumps for the Main Tank Farm, Alcohol
Tank Farm, and Ester Tank Farm are located within the secondary containment area for the
respective tank farm. To determine if liquids can be transferred between tanks, personnel
measure the receiving tank and verify the transferred material will fit.
All transfer piping at the facility is either exposed (above ground) for visual inspection or is
contained in a steel plate fabricated pipe trench (top of trench is parallel with existing grade).
Normal vehicular traffic does not pose a direct threat to above ground piping.
D. FACILITY TANK CAR AND TANK TRUCK LOADING/UNLOADING
Transfers of materials to and from outside sources (tank wagons and railcars) occur at two
locations at the Chemol facility;
l) Tank trucks load and unload to the west of the main plant and
2) Rail cars park in the rail car unloading area located west of the main tank farm.
D.I. Railcar Unloading
The rail car unloading area has a single connection point for unloading operations, which
precludes the opportunity for confusion in piping. The rail car unloading area services tanks in
the tank farm area (TF-1 through TF-7), which are equipped with local audible high-level alarms.
The rail unloading area is designed with a secondary containment system to prevent leaks and
drips from the rail cars from entering the environment; however, the containment area is unable
to control a major release occurring from a faulty valve or full tank car failure. Currently,
railcars are only used to receive non -hazardous raw materials that are solid at ambient
temperatures. They are only heated when the railcar is positioned over the containment structure.
This precludes the possibility material could leak from a railcar not positioned over the
containment Structure. See Section A.4 for additional information on the secondary containment
at this location.

D.2. Tank Truck Loading and Unloading
The tank truck loading/unloading area is located west of the main plant within the
secondary containment of the main plant. Like the tanks in the main plant, all of the leaks, drips
and spills are collected in the trench drains and processed within the wastewater pretreatment
system. Piping locations for loading and unloading operations in this area are labeled to indicate
their respective discharge locations.
The surface of the tank truck loading/unloading area is concrete. This surface is
periodically washed to minimize the tracking of chemicals outside of the containment structure
by tank wagons or forklift tires.
D.3. Monitoring of Transfer Operations and Equipment
All transfer operations are monitored by personnel throughout the transfer. Further, plant
personnel inspect any hoses, connection fittings, piping and pumps prior to starting the transfer
and during, the transfer.
E. SECURITY
Security is controlled by plant personnel being on -site 24 hours a day when the plant is operating.
When the plant is not operating; security personnel are on -site. Security personnel use a punch
card and monitoring panel system to ensure frequent visits to all tank storage areas. Part of the
security personnel's responsibilities includes at least bi-hourly visits to each of the monitoring
panels. Monitoring panels are located at each tank farm area and at multiple locations within the
main plant.
Lighting is sufficient throughout the facility to allow detection of a spill at night. .
F. SPILL PREVENTION AND MITIGATION PROCEDURES
F.I. Spills Outside of Containment Structures
Employees are required to immediately clean up any spill or leaks outside of containment
structures. Any spill that occurs outside of a containment structure that cannot be controlled is
immediately reported to emergency agencies by dialing 911. Further, Chemol will contract the
services of Shamrock Environmental to provide emergency remediation and response.
F.2. Spills Inside of Containment Structures
Spill of material inside of containment structures are either recovered for reuse or placed
into the plant's process sewer system. The actions taken are appropriate for the amount of
material spilled and its hazard level.
F.3. Training
All employees who work in the processing area are trained in the operation of equipment to
prevent discharges of process chemical into storm water. This training is held in conjunction

with Spill Prevention, Control and Countermeasure (SPCC) Training and includes a discussion
of material transfer and acceptance procedures, and applicable laws, rules and regt'lations. A
knowledgeable person provides this training with experience in spill response, containment and
control. Training is conducted at least once per year for these personnel.
During the training session, a briefing is held to assure adequate understanding of the SPCC Plan
and Stormwater Pollution Prevention (SPP) Plan. These briefings also highlight recent spill
events, failures, and precautionary measures. Records of employee training sessions are
maintained with the SPCC Plan and are kept for at least three years.
Additional annual training on uncontrolled spills occurs as part of the Emergency Action Plan
Training Program. Records of this training are maintained.
G. Waste Streams and Handling
G.I. Plant Process Sewer Liquid Waste
All rainwater and residual chemicals collected in any of the tank farms or production
areas enter the plant's sewer system. The materials are acidified to separate any oil layer from
the water layer. The water layer is separated, neutralized and discharged to the City of
Greensboro's Sanitary Sewer System. The grease layer is sold as a non -hazardous by-product
stream.
G.2. Solid Waste from Production, Warehouse, Maintenance, Laboratory and Office
Operations
Chemol's operations generate non -hazardous solid wastes that are sent to a licensed
landfill. The solid wastes are placed in one of two `rolloff ' containers. One of these containers
is within the plant's contaimment structure. Any runoff of rainwater from this container would go
into the main plant's containment structure.
The second solid waste dumpster is placed over a collection sump which collects any
rainwater runoff. Any runoff is then pumped into the main plant's process sewer.
G.3. Laboratory Hazardous Waste
Chemol's laboratory operations generate small quantities of hazardous waste. This waste
is removed by licensed hazardous waste haulers and incinerated. Records of waste generated and
its associated disposal are maintained.
H. Preventive Maintenance
Chemol has a preventive maintenance program involving scheduled maintenance on all
equipment. This program is currently being updated to enhance its effectiveness and formal
documentation. Further, Chemol has a work order system to repair any unplanned equipment
failures. Any maintenance activity required to address potential or actual stormwater
contamination is considered a high priority relative to other maintenance activities.

1. Pallet Storage
Chemol stores a variety of wooden pallets in uncontained areas. The large majority of
these pallets are new aA do not pose a potential to contaminate stormwater. A small number of
pallets (averaging below 50) have been used in the production area and could be contaminated
with small quantities of non -hazardous materials. Runoff from these pallets could potentially
contaminate stormwater. Currently, all used pallets are removed from the site by a pallet
recycler. Chemol plans to upgrade its handling of used pallets to minimize the potential for
stormwater contamination. Options being consider include, but are not limited to, placing a roof
over the storage area or disposing of contaminated pallets in the current "rolloff" containers
described in Section G.2.

Chemol Company, Incorporated
Permit NCS000048
Item 5: Significant Changes in Industrial Activity at the Permitted Facility
There have been three significant changes in activities since the last permit renewal application:
Change #1: Removal of the Vegetable Oil Tank {13V-1} from Service
This 92,000-gallon tank has been taken out of service. This will eliminate any potential
stormwater contamination resulting frorn the failure of this tank or its associated components.
Change 92: Installation of the Ester Tank Farm and associated tanks
A new tank farm with three storage tanks was installed. This tank farm is utilized to store
non -hazardous finished products. This tank farm is contained and any stormwater or other
material within the containment structure is pumped to the plant's process sewer. Further details
on this tank farm are listed under Item 4: Best Management Practices, Section A.3.
Change #3: Enhancement of Main Plant's Secondary Containment System and Process
Sewer System
The Main Plant's containment system has been enhanced by incorporating the existing
cooling tower within it boundaries. This precludes the possibility of excessive cooling tower
overflows from entering stormwater runoff.
Moving the process sewer lift pumps to within the Main Plant's secondary containment
structure has enhanced the Process Sewer System. Previously, these pumps were located outside
of the containment structure and adjacent to the sanitary sewer outfall. A lift pump failure could
have caused a discharge of untreated wastewater into the Sanitary Sewer. Further, any failure of
the pipes running to or from the lift pumps in the old location could have caused stormwater
contamination. Moving the lift pumps minimized the possibility of discharging untreated
wastewater to the sanitary sewer and the potential for stormwater contamination from a piping
system failure.
