PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The Permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. This Plan shall be considered public information in accordance with Part III, Standard `
Conditions, Section E, Paragraph 3 of this individual permit. The Plan shall include, at a
minimum, the following items:
l '. 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. The gFperal location
map (or alternatively the site map) shall identify whether each receiving water is
impaired (on the state's 303(d) list of impaired waters) or is loca� din a
watershed for which a TNIDL has been established, and what the parameter(s)
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 which
could be expected to be present in the stormwater discharge from each jutfall.
(c) A site map drawn to scale (including a distance legend) showing: 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, all drainage features and structures, drainage areas for each outfall,
direction of flow in each drainage area, industrial activities occw"' ng in each
drainage area, buildings, existing BMPs, and impervious surfaces. The site map
must indicate the percentage of each drainage area that is imperviou:;. .
(d) A list of significant spills or leaks of pollutants that have occurred at 'lie facility
during the three (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
Part II Page] of 10

Permit No. NCS000532
B, Paragraph 3. The permittee shall re -certify annually that the stormwater
outfalls have been evaluated for the presence of non-stormwater discharges.
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 stormwa:;. rn 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 ston-nwater runoff away from areas of potential contamination.
(b) Secondary Containment Requirements, and Records. Secondary containment is
required for: bulk storage of liquid materials, storage in any amount of Section
313 of Title III of the Superfund Amendments and Reauthorization Act (SARA)
Y water priority chemicals; and storage in any amount of hazardous substances, in
.order to prevent leaks and jpills from contaminating stormwater runoff. A table
.,._ar summary of all such'Lanks and stored materials and their associated secondary
containment areas shall be maintained. If the secondary containment devices are
connected to stormwater conveyance systems, the connection shall be controlled
by manually activated valves or other similar devices (which shall be secured
closed with;a_locking mechanism), 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 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 years.
(c) BMA Summary. A listing of site structural and non-structural Best Management
Practices (BMP) shall be provided. The installation and implementation of BMPs
shall be based on the. ;asessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and data collected
through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the speci lic.rationale for installation and implementation of the
selected site BMPs. The BMP Summary shall be reviewed and updated annually.
-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 the team) 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
Part IC Page 2 of 10

Permit No. NCS000532
person shall be on -site at all times during facility operations that have the potential to
contaminate stormwater runoff through spills or exposure of materials associated with the
facility_ operations. The SPRP must be site stormwater specific. Therefore, an oil Spill
Prevention Control and Countermeasure plan (SPCC) may be a component of the SPRP,
but may not be sufficient to completely address the stormwater aspects of the SPRP. The
common elements of the SPCC with the SPRP may be incorporated by reference into the
SPRP.
4. Preventative Maintenance and Good Hous,,keeping Program. A preventative
maintenance and good housekeeping progt�em shall be developed. The program shall list
all stormwater control systems, stormwater discharge outfalls, all on -site and adjacent
surface waters and wetlands, industrial activity areas (including material storage areas,
material handling areas, disposal areas, process areas, loading and unloading areas, and
haul roads), all drainage features and structures, and existing structural BMPs. The
program shall establish schedules of inspections, maintenance, and housekeeping
activities of stormwater control systems, as well as facility equipment, facility areas, and
facility systems that present a potential for stormwater exposure or stormwater pollution.
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 in writing and maintained
in the SPPP. N, _ e
5. Employee Training. Training'programs shall be developed artul-raining 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 storr.-; . ,, ter runoff. Facility personnel (or team)
responsible for implementing the training shall be identified, and their annual training
shall be documented by the signature of each employee'trained.
6. Responsible Party. The Stormwater Pollution Prevention Plan sha-H 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 penmittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a sigaicicant effect on the
potential for the discharge of pollutants to surface waters. A=aspects of the
Stormwater Pollution Prevention Plan shall be reviewed and updated on an annual
basis. The annual update shall include an updated list of si&mifi,�,ant spills or leaks of
pollutants for the previous three years, or -the notation that no spilis_have occurred. The
annual update shall include written re -certification that the stornr��,ater outfalls have been
evaluated for the presence of non-stormwater discharges. Each annual update shall
include a documented re-evaluation of the effectiveness of the BMPs listed in the BMP
Summary of the Stormwater Management Plan.
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
Part II Page 3 of 10

Permit No. NCS000532
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 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 -,nee
during the second half (July to December), with at least 60 days separating inspection
dates (unless performed more frequently than semi-annually). These facility inspe0ons
are different from, and in addition to, the stormwater discharge characteristic monitoring
required in Part II B and C of this permit.
9. Implementation. The permittee shall implement the Plan. Implementation of the Plan
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 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 representative storm event. The required
monitoring will result in a minimum of 20 analytical samplings being conducted over the term of
the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 0.1 inches of rainfall. The time
between this stor_a event and the previous storm event measuring greater than 0.1 inches must be at least
72 hours. A singly: storm event may have a period of no precipitation of up to 10 hours. For example, if
it rains but stops before producing any collectable discharge, a sample may be collected if the next rain
producing a dischargF •_�egins within 10 hours.

This site discharges to impaired waters experiencing problems with turbidity. If a Total
Maximum Daily Load (TMDL) is approved for this segment of Livingston Creek, the permittee
may be required to monitor for the pollutant(s) of concern in the future and submit results to the
Division of Water Quality. The Division will consider the monitoring results in determining
whether additional BMPs are needed to control the pollutant(s) of concern to the maximum
extent practicable.
If additional BMPs are needed to achieve the required level-ijf 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 permitted Stormwater Pollution Prevention Plan.
SECTION C: QUALITATIVE MONITORING REQUIREMENTS
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status and shall be performed as specified in Table 4, during the analytical
monitoring event. [If analytical monitoring is not required, the permittee still must conduct
quarterly qualitative monitoring.] Qualitative monitoring is for the purpose of evaluating the
effectiveness of the Stormwater Pollution Prevention Plan (SPPP) and assessing new sources of
stormwater pollution.
r
In the event an atypical condition is noted at a stormwater discharge outfall, the permittee shall
document the suspected cause of the tndition and any actions taken in response to the

Permit No. NCS000532
APPENDIX A. ACUTE TOXICITY TESTING FOR STORNIWATER OUTFALLS
L ANNUAL TESTING (PASS/FAIL ACUTE TOXICITY TESTING):
The permittee shall conduct acute toxicity tests on a yearly basis using protocols defined in the North
Carolina Procedure Document entitled "Pass/Fail Methodology for Determining Acute Toxicity in a
Single Effluent Concentration" (Revised -July, 1992 or subsequent versions). The monitoring shall be
performed as a "water flea" (Ceriodaphnia dubia) 48-hour static test.
Stormwater samples shall be collected as a single grab sample. Samples for self -monitoring purposes
must be obtained during a representative storm event. The tests will be performed during the first six
months of the year (January -June). .
If at any time there is significant mortality at a stormwater effluent concentration of 100%, the results
will be considered as a benchmark exceedance of toxicity.
All toxicity testing results required as part of this permit condition will be entered on the Stormwater
Discharge Monitoring Form (DMR) for the month in which it was performed, using the parameter code
TGA3B. One copy shall be submitted to Central Files, and one copy shall be submitted to the
Stormwater Permitting Unit as follows:
Attention: Central Files
Division of Water Quality
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
Attention: Stormwater Permitting Unit

Additionally, DWQ Form AT-2 for Acute Pass/Fail Tests (original) is to be sent to the following
address:
Attention: NC DENR 1 D`i'Q / Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621 `
Completed Aquatic Toxicity Test Forms shall be sent and postmarked to the Environmental Sciences
Section and Central Files no later than 30 days after the end of the month in which the test was
conducted.
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual chlorine
of the stormwater toxicity sample must be measured and reported if chlorine is employed for disinfection
of the stormwater discharge.
If there is no stormwater discharge from the facility during the months which toxicity monitoring is
required, the permittee will complete the information located at both the top of the aquatic toxicity (AT)
Appendix A: Page 1 of 4

Permit No, NCS0005 32
test form and DMR indicating the facility name, permit number, stormwater outfall number, county, and
the month/year of the report with the notation of "No Flow" in the comment area of the form. The
permittee shall submit three (3) "no flow" reports: one report shall be submitted to the Environmental
Sciences Section, one to the Stormwater Permitting Unit (SPU) Central Office, and one report shall be
sent to Central Files at the address cited above. The permittee shall submit acrtte toxicity monitoring as
outlined above, at the nest available representative storm event.
II. ACTIONS FOR FAILURE OF PASS/FAIL TESTING.
Should any single scheduled monitoring indicate a failure to meet toxicity benchmark levels, a
series of measures shall occur:
1) Within 30 calendar days from availability of the test results, the pf.i.nittee shall contact the
Division SPU Central Office and the Regional Office Supervisor in writing.
a. If other stormwater monitoring parameters have exceeded benchmark values, the
Regional Office may exempt the permittee from additional acute toxicity monitoring
(other than regularly scheduled test periods), at the Regional Offiice's discretion. The
permittee shall continue to address all other stormwater parameter benchmark
exceedances.
b. .if the permittee has not exceeded other benchmark values, or if the Regional Ot ice
does not exempt the permittee from additional monitoring, the permittee shall
immediately institute monthly acute toxicity monitoring with a 48-hour multiple cs*ion
test per U.S. EPA Method 2002.0: "Methods for Measuring the Acute Toxicity of
Effluents to Freshwater and Marine Organisms," EPA 821/R-02/012 (October 2002).
Ill. ACTIONS IFMONTHLYMONITORING IS INSTITUTED (AIULT IPLE-DILUTION
TESTING):--):
'If monthly acute toxicity monitoring is instituted per Section II above, the permittee shall perform
the tests per the following conditions:
1) An LC50 greater than 1.00% shall be used as a benchmark passing endpoint; Stormwater
Permitting Unit (SPU) Central Office may determine alternative endpoints as"passing" on a
case -by -case basis, depending on the specific characteristics of the facility's stormwater
discharge. Multiple dilution tests will be run at 100%, 50%, 25%, 12.5%, 6.25% and 0°
1 stormwater unless other test concentrations are determined appropriate by the Stormwat.ep;
Permitting Unit (SPU) Central Office.
2) Multiple Dilution Test Results shall be submitted on form AT-1 for Acute Multiple Dilution z
Tests. The parameter code is TAA3B. The permittee shall:
a. Submit form ATA (original) to the DWQ Environmental Sciences Section.
b. Send a completed a Stormwater DMR form (original) with an attached form AT-1
(original) to DWQ Central Files.
c. Send a completed a Stormwater DMR form (copy) with an attached form AT-1 (copy) to
the DWQ Stormwater Permitting Unit.

Permit No. NCS000532
3) The permittee shall perform monthly acute toxicity monitoring until one of the follo.,vina
permit conditions is met:
a. THREE CONSECUTIVE MULTIPLE -DILUTION TESTS PASS. No further tests
need to be performed until next regularly scheduled test period.
-OR-
b. EITHER OF THE FOLLONVING OCCURS:
i. A TOTAL OF FIVE MULTIPLE -DILUTION TESTS FAIL
-OR-
ii. THREE CONSECUTIVE MULTIPLE -DILUTION TESTS FAIL.
If either of the above occurs, fiirther actions are necessary. See IV. below.
4) The permittee shall submit a summary of all test results for the multiple dilution test series
along with complete copies of the test reports as received from the laboratory to the Regional
Office Supervisor, to DWQ Central Files and to SPU. These shall be sent and postmarked within
30 calendar days of receipt of the last failed or passed multiple -dilution test (as described above
in III, 3)),
IV. ACTIONS FOR FAILURE OF MULTIPLE DILUTION TESTS TRE TRI or OTHER
MEASURES):
If the permittee fails either A TOTAL OF FIVE multiple -dilution tests or THE THIRD
CONSECUTIVE multipleAilution test as desc:-Wd in Section III 3) b., the permittee shall.execute
the following:
1) A toxicity reduction evaluation (TRE) shall be automatically instituted. Within 30 calendar days
from availability of the test results, the permittee shall contact the Division SPU Ccntrai'Office
and the Regional Office Supervisor -in writing.
a. The permittee shall submit one copy of a plan for conducting a TRE to the DWQ SPU,
and one copy to the DWQ Environmental Sciences' Section. These copies shall be
submitted within 60 calendar days of the'date of DWQ SPU's direction'to perform the
TRE.
b. This plan must be approved by DWQ SPU before the TRE is begun. A schedule for
completing the TRE shall be established in the plan approval. A Toxicity Identification
Evaluation (TIE) may be a component of the TRE.
c. Upon DWQ's approval, the TRE schedule may be modified if toxicity is intermittent
q during the TRE investigations. A revised WET test schedule may be established by
DWQ for this period. �.
2) Additionally after the first year that TRE results have been collected.and submitted, depending
on results the Regional Office may (among options):
• Require the permittee to install structural stormwater controls;
• Require the permittee to implement other stormwater control measures or BMPs;
• Require the permittee to collect and treat the discharge and/or eliminate the
discharge;
• Require that the permittee implement site modifications to qualify for the No
Exposure Exclusion; or
Appendix A: Page 3 of 4

Permit No. NCS000532
• Require that the pennittee perform up -stream and downstream biological assessment
in the receiving water.
V MEASURES APPLICABLE TO ALL TESTS:
All acute toxicity test results shall be submitted in a concise summary at the end of the five year
permit term. One copy of this report shall be sent to the Regional Office Supervisor, one copy to the
FPU Central Office, and one copy to the DWQ Environmental Sciences Section.
Should any test data from either these monitoring requirements or tests performed by the North Carolina
Division of Water Quality indicate potential impacts. to the receiving stream, this permit may be re-
opei., i and modified to include alternate monitoring requirements.
If the Permittee monitors any pollutant more frequently than required by this permit, the results of such
monitoring shall be included in the calculation & reporting of the data submitted on the DMR & all
Acute Toxicity Forms submitted.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival and appropriate environmental controls, shall constitute an invalid test and will require

XII. NATURE OF BUSINESS (provide a brief description)
Oak -Bark operates two distinct operations. Dry Projects & Pharma Plant
The Dry Projects Plant, located on the Southwest guardant of the plant site, produces animal feed additives.
There are three different products produced here. About 57% of the plant's production is Zinc Mintrex, about 27%
is Copper Mintrex and the remaining 16% is Manganese Mintrex.
The Mintrex process consist of reacting a weak acid (Alimet) with one of the above three minerals. This produces
a weak exothermic reaction. The product is then vacuum dried and milled to meet particle size.
All waste associated with the production of Mintrex are Non -Hazardous and are shipped off site to a state
approved disposal site.
The Pharma Plant is currently idle and has been idle since 2004. There are currently no Storm Water Outfalls
associated with this plant

Special Issues Explanation:
• Site has since been split up from one previous owner, Wright Chemical, into three owners (Oak -Bark,
Hexion, and Silar). Oak -Bark Corporation now retains a small portion of the site and has applied for a
separate individual NPDES permit.
o Outfalls and responsibilities and permits need to be defined for each company.
■ Hexion's stormwater outfalls are 003, 004, 006, 008, and 009 (from 2008 application).
■ Oak -Bark Corp. manufacturing area drains to stormwater outfall 007.
■ Silar areas drain to stormwater outfalls 001, 002, and 005.
0 3 Permits for Hexion, Oak -Bark and Silar should be coordinated.

Owner's Other Permits:
• 09749R00 — Synthetic Minor Air Permit
• WQ0005699 — Sludge Disposal Monofill
• WQ0003361 —Closed-loop Recycle (non -discharge)
2. General Observations:
• Several dry products stored in the warehouse; good housekeeping will be essential to prevent
residues from being tracked -out and exposed to stormwater. Several materials transported inside by
forklift on delivery.
• Oils may also be a potential contaminant from any truck traffic in drainage area. Also noted oils and
lubricants stored in the warehouse.
• See application for more details.
• 2007 Toxic Release Inventor�-is available for Hexion and Wright (entire site); reported emissions
included acrylamide, ammonia, analine, copper compounds, formaldehyde, n-hexane, methanol,
polycyclic aromatics, toluene, and zinc compounds.
3. Impairm_ ent: Proposed to be added to the 303(d) list for turbidity impairment. The 2005 Basinwide Plan notes
low DO impacts to aquatic life, but this may be an older listing. The Plan does not discuss the creek in detail.
4. Threatened and Enda�: No threatened or endangered aquatic animals identified nearby.
5. Location: This site is part of a larger site that used to be operated by Wright Chemical. Most recently the site
has been divided by three companies: Silar, Hexion, and Oak -Bark. This permit for Oak -Bark applies to the
manufacturing activities on the_ southwestern corner of the property and stormwater discharges through
outfall 007.
6. Industrial Changes Since Previous Permit: N/A; see description of current activities.
7. Analytical Monitoring Notes. Application indicated there had been no recorded flow from SDO 007 because a
small retention pond captures and contains the runoff from most storms (WiRO confirmed overflow likely only
in large events). Sample taken from the pond on 5/22/09 for analysis (see next page).
8. Qualitative Monitoring Notes: N/A.
9. Consideration of Acute Toxicity Monitoring: Note that Silar and Hexion portions of this site under separate
individual Stormwater Permits have annual Acute Toxicity (WET) Monitoring requirements. This permit does
not include that requirement because stormwater contamination problems have not been as severe at this
outfall and because discharge is infrequent (only in large events; confirmed by WiRO).

Permit Recommendations;
1. Parameters in this permit include all chemicals reported by the applicant for the May 2009 sampling event,
except for lead.
> BOD and COD are appropriate for the various organic chemicals stored and used on Oak-Bark's area of the
facility, and the rest of the site has had numerous instances of elevated levels in the stormwater discharge
(Outfalls 002, 003, 004, 005, & 006).
..> T55 is indicative of housekeeping or other problems, particularly the effectiveness of the retention pond
,(structural BMP) for this drainage area; TSS is also appropriate for a discharge to receiving waters plagues with
turbidity problems.
> Ammonia, TKN (organic nitrogen), and Nitrate/Nitrite were reported below benchmarks in the submitted
analysis but are present with this industrial activity. It is possible the retention pond is affected by ammonia`"
emissions from other parts of the site. If levels prove not to be a problem during this permit cycle, future
reviewers may consider scaling back or eliminating monitoring.
> Total Lead is not proposed in the monitoring scheme because levels were well below the 0.03 mg/I
benchmark, and it does not appear to be present in the -materials here. Noted that there were very few
benchmark exceedances in data collected from other outfalls at this site between 2000-09 (see attached
summary for Hexion and Silar outfalls).
> Total Copper, Zinc, and Manganese included because activity at this site involves production of feed
additives with these metals. Note -benchmarks may change prior to issuance depending on final strategy for 'r
5PU to iMplemer.)r new dissolved metals standards.
> Hexamine and formaldehyde are included in the permit because they are potential pollutants from past L_
activities and/or activities in close proximity to Oak-Bark's operations. The sample's formaldehyde
concentration was very close to the benchmark of 0.5 mg/I.
> pH is included because of its use as a general and immediate indicator of problems (especially with acid
storage at this facility), as well as its importance in interpreting other data such as metals.
> Total Petroleum Hydrocarbons (TPH) is included because several oils are stored at this site, and fork-lift
traffic may introduce such materials into the discharge. An alternative to just Oil and Grease (O&G), TPH can
v
be measured with the same method EPA has approved for 0&G: Method 1664, but using Silica Gel Treated N-
Hexane Extractable Material (SGT-HEM) and an additional step that removes polar/fatty non -petroleum based
material from the sample. This method is not compound -specific but is less costly, and still provides an
estimate of petroleum hydrocarbon concentration. This parameter is better targeted for petroleum based
materials than 0&G, which can include animal -based fats and oils.
2. All analytical monitoring is quarterly during a representative storm event as defined in Part it Section B. This
frequency is higher than the standard semi-annual, but is consistent with proposed monitoring in draft
permits for the other manufacturers at this site (Hexion and Silar). The frequency is also appropriate given
DWQ's elevated concern about stormwater contamination from past activities. Because the retention pond
discharges more rarely, Oak -Bark will probably not see flow from its one outfall for many of those quarters.
3. Benchmarks for analytical monitoring are included with this draft permit. Exceedances of benchmark values
require the permittee to increase monitoring, increase management actions, increase record keeping, and/or
install stormwater Best Management Practices (BMPs) in a tiered program. If sampling results are above a
benchmark value, or outside of the benchmark range, for any parameter at any outfall then the facility should
follow the Tiered response guidelines.
4. The permittee is required to collect all of the analytical and qualitative monitoring samples during a
representative storm event as defined in Part II Section B. Qualitative monitoring is required to coincide.
5. The flow reporting requirement is not included, per DWQ revised strategy. Total rainfall is in the permit,
however, and can be used with impervious area information to estimate flow. Impervious area detail is
required to be documented in the permittee's SPPP.
6. Vehicle maintenance monitoring included, if ever applicable at this site (proposed quarterly to be consistent
Page 5 of 6

NCS000532
with other monitoring, which would occur at the same outfall).
Recommendations: Based on the documents reviewed, the application information submitted on June 4, 2009
and June 18, 2009 are sufficient to issue an Individual Stormwater Permit.

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'Pa<< 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 thephysicalfacility r.:?d the
potential pollutant sources which may be expected tole tribute to contamination of
stormwater discharges. The site plan shall contain ti; 'following:
(a) A general location map (USGS quadrangle;_map or appropriately drafted
equivalent map), showing the facility}s Iocation.in relation to transportation routes
and surface waters, the name of the'recetiving.water(s) to which the stormwater
outfall(s) discharges, or if the discharge pis,Jo 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. The'general location
map (or alternatively:thi Vsitd.map) shall identify whether each receiving water is
impaired (on the state's 303(d)`Iist of impaired waters) or is located in a
watershed for which'a TMDL has been established, and what the parameter(s)
A
of concern are.4•'
h
(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 which
could be expected to be present in the stormwater discharge from each outfall.
(c) A site map drawn to scale (including a distance legend) showing: 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, all drainage features and structures, drainage areas for each outfall,
direction of flow in each drainage area, industrial activities occurring in each
drainage area, buildings, existing BMPs, and impervious surfaces. The site map
must indicate the percentage of each drainage area that is impervious.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the three (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 Ill, Standard Conditions, Section
Part H Pa-e I of 10

Permit No. NCS000532
B, Paragraph 5. The permittee shall re -certify annually that the stormwater
outfalls have been evaluated for the presence of non-stormwater discharges.
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 fr6ffi areas of potential contamination.
(b) Secondary Containment Requiremerits.'and Records. Secondary containment is
required for: bulk storage of liquid rriaterials; storage in any amount of Section
313 of Title III of the Superfund Amendments and Reauthorization Act (SARA)
water priority chemicals; and storage_.in any amount of hazardous substances, in
order to prevent leaks and spills'fro contaminating stormwater runoff. A table
or summary of all such tanksrdnd stored materials and their associated secondary
containment areas ,shall.be maintained. If the secondary containment devices are
connected to st_orrmwater conveyance systems; the connection shall be controlled
by manually activated valves or other similar devices (which shall be secured
closed with a lockingmechanism), and any stormwater that accumulates in the
containment area shall be at a minimum visually observed for color, foam, outfall

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of 20 analytical samplings being conducted over the term -of
the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 0.1 inches of rainfall. The time
between this storm event aild the previous storm event measuring greater than 0.1 inches must be at least
72 hours. A single storm event may have a period of no precipitation of up to 10 hours. Tor example, if
it rains but stops before producing any collectable discharge, a sample may be collected if the next rain
producing a discharge begins within 10 hours.
