Subject: Relief from Monthly Stormwater Sampling
Stormwater Permit # NCG030440
TimkenSteel — Tryon Peak

Dear Mr. Morrow:
E
ROY COOPER
Governor
MICHAEL S. REGAN
Secretary
WILLIAM E. VINSON, JR
Interim Director
The Division has reviewed your request for regulatory relief from monthly stormwater sampling.
The facility was inspected on March 15, 2018, and was found to be in compliance with the tiered
response actions. -and other conditions of the NCG030000 General Permit.
;.
As observed during. the inspection and due to facility actions taken regarding investigating and
correcting exceedances, the Division is granting the facility regulatory relief from the tier
responses for copper and zinc. Upon receipt of this letter, the subject facility may resume the permit
specified semi-annual analytical monitoring. This relief letter remains in effect through the
subsequent reissuance of the NCG030440 permit. This decision applies only to copper and zinc
benchmarks. A benchmark exceedance of any other parameter listed in your permit will
trigger the tiered response actions as described in the general permit.
You must notify this office, in writing, within five business days if you become aware of any
significant source of copper and zinc at your facility that has the potential to be exposed to
stormwater. The relief granted in this letter is contingent upon the current industrial practices at
TinikenSteel Corporation. If industrial practices change and copper or zinc does become a
significant stormwater exposure risk or significant copper or zinc values have been recorded during
a regular sampling event, then this office reserves the right to withdraw this decision and reinstate
the permit specified tiered response or other actions that may be warranted by the new set of
circumstances.
Please retain and append this letter to your Stormwater Pollution Prevention Plan (SPPP) or permit.
If you have any questions or need further information, please contact Shawna Riddle at (828) 296-
4500.

Inspection Date: 0211012016 Inspection Type : Compliance Evaluation Reason for Visit: Other
Inspection Summary:
While on site I, Shawna Riddle', inet'with Bob Morrow, Jody Splawn, Robert Teter, and Phillip Rhodes.
In 2012 the facility was issued a new stormwater permit. The permit package was not delivered to the Polk County plant
from Corporate and the nevr`monitoring form for Zn and Cu was not implemented. The company split in 2014 and a new
company was formed. In 2015 the company realized that they were not using the correct sampling form including Zn and
Cu. The facility has been sampling for Zn and Cu since April 2015. However, they requested an inspectionlmeeting at the
facility to discuss exceedances. The facility is now in Tier 1111 for Outfall 001 and 002 for Zinc.
We discussed the potential sources for Zinc and Copper and did a walk-thru of the facility and of the property including
observations of outfails (001 '&'002). `
Inside the plant 1 noted grit/dust on the floors. Fork lifts are used inside/outside the plant. I recommended regular floor
cleaning (floor scrubber) to adaress'this issue. It is essential that the floor cleaning water be disposed of properly, since
this water could have a heavy"metal load. The facility has 2 buildings. The lower building in not in operation (roof has
galvanized finished). Upper expansion of the main building has a galvanized roof finish as well. The facility has raw material
composed of solid steel bar and tube stored outside on racks around the footprint of the building. The facility has no outside
manufacturing or processing activities. Diesel fuel is stored in two above storage tanks equipped with steel secondary
containment. All finished products are stored inside and no waste is disposed of at the site.
We discussed housekeeping practices and other sources for zinc and copper. The facility has a spreadsheet of potential
sources for further investigation of zinc and copper at the site. They have recently moved raw materials 17-4PH inside.
These materials had a concentration of 3.2% copper. They have also revaluated their HVAC unit cleaning procedures. Other
suggestions are to further investigate the impact of roof runoff, scrubbing floors (forklift trafficibrake wear/tires), cleaning the
parking lot in the front of the building (brake wear), establishing a groundcover on the area leading to outfall 001 (where
rocks are present).
Outfall 001 pipe is galvanized - as discussed onsite - start sampling outfall 001 at the inlet of the pipe and at the outlet of
the pipe. Take the samples at the same time to see if the pipe is contributing to the high copper/zinc numbers. The
drainage leading to Outlet 001 is from the employee/visitor parking lot, the paved side/back lot area and some downspout
lines.
Outfall 002 there is no galvanized piping used. However, the drainage leading to 002 encompasses both buildings, alloy
steel bar tubing, dumpsters, metal storage luger, pallets, and traffic from materials being received and shipped, and forklift
traffic. This area is too large to put under cover.
The facility will continue work with the Region during its sampling and investigating of potential sources for copper and zinc.
Note: The facility is required to perform monthly monitoring until 3 consecutive sampling event fall below the benchmark
values.

RE: Stormwater permit
HI Jody,
Good to hear from you.
Unfortunately, the stormwater program was moved from my Division in August of 2013 and given to the Land Resources
folks. I have cc'd Laura Herbert here as she is the Asheville Supervisor for that group. She can be reached at the same phone
number as I am if you need future assistance.
However, I don't mind assisting you with your question. Go to Part II Page 5 of 10 Table I Footnote #4. (Total Toxic Organics
sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes.) This sentence states "only„ for those facilities performing....(}. If you are
not performing those operation at your facility then you do not have to do TTO. You do not need to do anything to request
removal of the requirement, as it is not required if you are not performing those operations.
If you are performing those operations and want to get out from under the TTO requirement, then see the next page up
(page 4 of 10) #10 Solvent Management Plan.
Hope this helps,

Hi Linda
You visited our facility several years ago and I remember discussing the possibility of removing our TTO sampling
requirement as we do not perform any metal finishing operations.
Could you tell me what I would need to do in order to remove this requirement? I have attached a copy of our permit.

Hi Andrew,
That's correct —you don't need legal documentation of transfer for a Name Change only.
Also, the legally responsible person can sign the Permittee Certification, rather than the Applicant Certification (since
this is not a transfer, but the Permittee is the same).
Yes, a plant manager or someone delegated by the company to sign documents in accordance with NPDES permit
requirements should sign. See signatory requirements in the back of your stormwater permit. Most say something like
this:
Signatory Requirements
All applications, reports, or information submitted to the Permitting Issuing Authority shall be signed
and certified [40 CFR 122.41(k)],
a. All [Notices of Intent to be covered under this general permit shall be signed as follows:
(1) For a corporation: by a responsible corporate officer. For the purpose of this Section, a
responsible corporate officer means: (a) a president, secretary, treasurer or vice president
of the corporation in charge of a principal business function, or any other person who
performs similar policy or decision making functions for the corporation, or (b) the manager
of one or more manufacturing, production, or operating facilities, provided, the manager is
authorized to make management decisions which govern the operation of the regulated
facility including having the explicit or implicit duty of making major capital investment
recommendations, and initiating and directing other comprehensive measures to assure
long term environmental compliance with environmental laws and regulations; the manager
can ensure that the necessary systems are established or actions taken to gather complete
and accurate information for permit application requirements; and where authority to sign
documents has been assigned or delegated to the manager in accordance with corporate
procedures.
(2) For a partnership or sole proprietorship: by a general partner or the proprietor,
respectively; or
(3) For a municipality, State, Federal, or other public agency: by either a principal executive
officer or ranking elected official [40 CFR 122.221.
b. All reports required by the general permit and other information

A couple quick questions about the form you sent:
1) Considering our situation is a name change only, am I correct that accompanying legal documentation is not
necessary ?
2) Can I sign the Applicant Certification or does the person legally responsible for the permit have to sign (in this
case, our plant manager)?
Thanks in advance,
Andrew Farber

Subject: RE: Timken Tryon Peak plant storm water results (Columbus, NC)
Thanks Jody,
I will take note of the outfall numbers. I had a chance to go through your data. One parameter (bis(2-
Ethylhexyl)phthalate 9.8 ug/L) was over the E.P.A. National Criteria, but is not likely an issue at your facility, it
could be related to the lab or plastics in general. I was in the area awhile back and drove by your facility and saw the
improvements associated with the erosion issue. I also saw the access path created for sampling at the other outfall. I
noticed there is another stormwater discharge outfall pipe next to your outfall pipe. Remember when sampling at that
location to sample what comes out of your pipe only. Do not sample in the stream channel or pooling area, that would
incorporate someone else's discharge (possibly a D.O.T. culvert) and you only need to account for your stormwater
discharge.

Linda,
have attached stormwater sampling results conducted at our facility on
9/27/2010. We conducted testing on both outfalls per your request.
On your correspondence dated Feb.18 2010 your noted outfall 2 as the
discharge that we had not previously taken a sample from. The outfall you
are referring to is labeled outfall 1 on our site map. It is also referenced as
outfall 1 in the Analytical monitoring report.
We repaired all erosion issues leading to an inlet drain associated with outfall 1
well in advance of collecting the stormwater sample. We also now have pH calibration
solutions onsite to ensure that our pH meter is working properly.

is
Please let me know if you need anything further from this sampling event. I will
forward you the results from our next event when collected.

Dear Mr. Lake:
JF I LEI
Resources
A Stormwater Permit Compliance Inspection was conducted at the Timken facility in Polk
County, NC on February 11, 2010. Present during the inspection was Linda'Wiggs and Jody
Splawn. The facility was found to be in compliance with permit NCG030440.
The following observations and recommendations were noted during the Division of Water
Quality (DWQ) inspection:
Dee Freeman
Secretary
Stormwater Discharge Outfall 2
A second Stormwater Discharge Outfall monitoring point needs to be monitored. Please add the
second Stormwater Discharge Outfall (SDO 2), which receives stormwater from the storage area
to the right of the building, to your site plan and monitoring schedule. An inlet drain that is
associated with this SDO 2 is located in a grassy area and has an erosion gully preceding it that
needs to be fixed prior to your sampling event in order to avoid elevated Total Suspended Solid
(TSS) results. Along with SDO 1, SDO 2 will require all Analytical and Qualitative monitoring,
including Total Toxic Monitoring.
H Monitoring
A pH meter is located onsite for pH analysis. However, calibration and probe storage solutions
necessary for accurate meter analysis are not onsite. Refer to the manufacturer instructions for
proper calibration and storage requirements.
Analytical Stormwater Monitoring Submittal
Please submit the next two sampling events analytical monitoring results from both of the
Stormwater Discharge Outfalls to the Asheville Regional Office (ARO) at the following address:

Inspection Date: 02/11/2010 Inspection Type: Compliance Evaluation Reason for Visit: Routine
Inspection Summary:
Most of the site drains via conveyances to a basin at bottom of hill. This basinthardwood weltand is very large and will
treat the stormwater. The area to the right of the building does have a storage area that drains to a stormdrain via
overland flow which is considered SDO 2 and needs to be monitored.
There is an erosion gully leading to SDO 2 stormdrain. Prior to sampling this outfall the erosion gully needs to be fixed to
avoid exceeding TSS benchmark.
During the inspection no chemicals were stored outside, however alot of raw material is stored outside.
It needs to be determined if pH meter is working properly. The facility needs to buy pH calibration solutions for meter to
determine if readings are accurate.

Comment: A second SDO was located and needs to be added to site plan.
No spills have occurred in the last 3 years.
Alternative to practices has not recently been needed. However, depending on
analytical resluts from SDO 2 a feasiblity study may be needed if benchmarks are
exceeded.
There were no chemicals stored outside at time of inspection.

Comment: Will need to add SDO 2 to monitoring schedule. All parameters at this time
are to be monitored. This inpsection did not reveal any concerns with chemicals being
stored outside, so after several monitoring results below benchmark are achieved at
both SDOs, the facility should consider developing a Solvent Mangement Plan to avoid .
TTO sampling.

Comment: A second SDO was located. Onsite rep and Canton Ohio rep thought this
area had representative outfall status. There are no records of Representative Outfall
status in the Asheville Office, This SDO needs to be added to site plan and monitored.
Unlike SDO 1, this SDO has no treatment and has the potential of delivering pollutants
to the adjacent waters. Monitoring will determine if this is a concern. Facility has been
told to send analytical results to the Region office for the next 2 sampling event.

Subject: NPDES Stormwater Permit Coverage Renewal
The Timken Company - Tryon Peak
COC Number NCG030440
Polk County
Dear Permittee:
In response to your renewal application for continued coverage under stormwater General Permit NCG030000 the Division of
Water Quality (DWQ) is forwarding herewith the reissued stormwater General Permit. This permit is reissued pursuant to the
requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between the state of North
Carolina and the U.S. Environmental Protection Agency, dated December 6, 1983.
The following information is included with your permit package:
• A new Certificate of Coverage
• A copy of stormwater General Permit NCG030000
• A copy of a Technical Bulletin for the General Permit
• Five copies of the Discharge Monitoring Report (DMR) Form
• Five copies of the Qualitative Monitoring Report Form
The General Permit authorizes discharges of stormwater only, and it specifies your obligations with respect to stormwater
discharge controls, management, monitoring, and record keeping. Please review the new permit to familiarize yourself with all
the changes in the reissued permit.
The more significant changes in the General Permit since your last Certificate of Coverage include the following:
• Part I Section A - A new notation that the No Exposure Exclusion from permitting option may be available to the
permittee.
• Part I Section A - A new provision that facilities draining to 303(d) listed waters, or in watersheds with an approved TMDL,
may not be eligible for renewed coverage under the General Permit.,
• Part II Section B Table 1 - An increased sampling frequency from once per year to twice per year.
• Part 11 Section B Table 3 - Benchmark concentrations now replace cutoff concentrations; the elimination of the option to
avoid sampling based on cutoff concentrations.
• Part 11 Section B - New provisions requiring the permittee to execute Tier One and Tier Two response actions, based on
the first benchmark exceedence (Tier One) and the second consecutive benchmark excoodence (Tier Two). Tier Two
requires that the permittee institute monthly monitoring instead of twice -per -year monitoring, until three consecutive
monitoring events show no benchmark exceedences.
• Part II Section B - A new provision that four exceedences of any particular benchmark will trigger increased DWQ
involvement in the permittee's stormwater management and control actions. DWQ may direct the permittee to apply for
an individual permit, or may direct the implementation or installation of specific stormwater control measures.
DWQ received a number of comments on a series of general permits similar to this one. A full response to comments can be
found at http://ncwaterquality.org/su/industrialgpinfo.htm. Some comments resulted in permit modifications, others are
addressed in the response document or Fact Sheet. A few specific requests for clarification are addressed below.
1. What is the deadline for having a revised SPPP that reflects the provisions of the new General Permit? DW O will require
that the permittee have a revised, complete SPPP no later than six months after the date of issue of that permittee's new
Certificate of Coverage.
2. Must analytical results be by a certified lab? What about pH measurements? All analytical results obtained to satisfy
NPDES permit requirements must be certified, as directed in North Carolina regulations at 15A NCAC 2H .0800, and as
administered by DWO's Laboratory Section Certification Branch. This includes field pH measurements.

To whom it may concern:
Please find attached revised TimkenSteel-Tryon Peak Semi -Annual Stormwater Discharge
Monitoring Reports for the North Carolina Division of Water Quality General Permit No.
NCG030000. Our General Permit No. is NCG030440. The reports were generated from
data dating back from June 2013. The issue of concern here is for the listed values for pH.
During a corporate review of the sampling and reporting procedures in place here at the
plant, we discovered that the pH values were incorrectly reported. For each sample event a
field pH sample was done on each sample using a properly calibrated pH meter and the
sample results recorded. We then mistakenly requested that the laboratory measure pH.
The laboratory value was then reported in each instance on our Monitoring Reports. As
you may know, pH is to be recorded in the field due to the lag time in the laboratory
receiving the sample for analysis. In each case the pH values measured in the field or at the
plant was higher than the pH values recorded at the lab. The laboratory pH values were
outside the holding time and were inappropriately reported. Fortunately, the pH values
measured using the meter here at the plant were recorded and available for review. We
wish to correct the record by revising each report where the laboratory value was used
with the appropriate plant or "field" measurement. Our Regional representative, Shawna
Riddle, Environmental Senior Specialist, North Carolina Dept. Environmental Quality
Asheville Regional Office, Energy Mineral and Land Resources has also been advised and is
in receipt of corrected copies.

PART I — INTRODUCTION
SECTION A: GENERAL PERMIT COVERAGE
All persons desiring to have facilities covered by this General Permit must register with the Division
of Water Quality (DWQ) by the filing of a Notice of Intent (N01) and applicable fees. The NOI shall be
submitted and a certificate of coverage issued prior to any point source discharge of stormwater
associated with -industrial activity to the surface waters of the state.
Any owner or,operato,r,not wishing to be covered or limited by this General Permit may make
application for an individual NPDES permit in accordance with NPDES procedures in 15A NCAC 2H
.0100, stating the reasons supporting the request. Any application for an individual permit should
be made at least,,180 days prior to commencement of discharge.
This General Permit does not cover activities or discharges covered by an individual NPDES permit
until the individual permit has expired or has been revoked. Any person conducting an activity
covered by an individual permit but which could be covered by this General Permit may request
that the individual permit be revoked and coverage under this General Permit be provided.
If industrial materials and activities are not exposed to precipitation or runoff as described in 40
CPR §122.26(g), the facility may qualify for a No Exposure Exclusion from NPDES stormwater
discharge permit requirements. Any owner or operator wishing to obtain a No Exposure Exclusion
must submit a No Exposure Certification Notice of Intent (N01) form to the Division; must receive
approval by the Division; must maintain no exposure conditions unless authorized to discharge
under a valid NPDES stormwater permit; and must recertify the No Exposure Exclusion annually.
Any facility may apply for new or continued coverage under this permit until a Total Maximum
Daily Load (TMDL) for pollutants for stormwater is established. A TMDL sets a pollutant -loading
limit that affects a watershed, or portion of a watershed, draining to a specific impaired water. For
discharges to watersheds affected by a TMDL, coverage under this permit may depend on the
facility demonstrating it does not have reasonable potential to violate applicable water
quality standards for those pollutants as a result of discharges. If DWQ determines that
discharges have reasonable potential to cause water quality standard violations, the facility shall
apply for an individual permit 1.80 days prior to the expiration date of this General Permit. Once
that individual permit is effective, the facility will no longer have coverage under this General
Permit. Note that the permittee must identify impaired waters (scheduled for TMDL development)
and waters already subject to a TMDL in the Site Overview, as outlined in the Stormwater Pollution
Prevention Plan, Part II, Section A.
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 in this permit.
Part i Page 1 of 2

Permit No. NCG030000
SECTION B: PERMITTED ACTIVITIES
Until coverage under this permit expires or is modified or revoked, the permittee is authorized to
discharge stormwater to the surface waters of North Carolina, or to a separate storm sewer system,
which has been adequately treated and managed in accordance with the terms and conditions of
this General Permit.
Any other point source discharge to surface waters of the state is prohibited unless it is an
allowable non-stormwater discharge or is covered by another permit, authorization, or approval.
The discharges allowed by this General Permit shall not cause or contribute to violations of
Water Quality Standards.
Discharges authorized by this permit and site operations must meet applicable wetland standards,
as recorded in 15A NCAC 213.0230 and .0231, and water quality certification requirements as
outlined in 15A NCAC 2H .0500.
This permit does not relieve the permittee's responsibility for compliance with any other applicable
federal, state, or local law, rule, standard, ordinance, order, or decree.

PART II MONITORING, CONTROLS, AND LIMITATIONS FOR PERMITTED
DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The permittee shall develop and implement a Stormwater Pollution Prevention Plan (SPPP). The
SPPP shall be maintained on site unless exempted from this requirement by the Division. The SPPP
is public information in accordance with Part 111, Standard Conditions, Section E, paragraph 3 of this
permit. The SPPP shall include, at a minimum, the following items:
1. Site Overview. The Site Overview shall provide a description of the physical facility and the
potential pollutant sources that may be expected to contribute to contamination of stormwater
discharges. The Site Overview 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 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 located in 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 now 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.
(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. An annual 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 rainfall and run-on flows. Wherever practical, the permittee
shall prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations. In areas where elimination of exposure is not
practical, this review shall document the feasibility of diverting the stormwater run-on
away from areas of potential contamination.
(b) Secondary Containment Requirements and Records. Secondary containment is
required for: bulk storage of liquid materials includingpQtroleum products: storage in any
amount of Section 313 of Title I11 of the Superfund Amendments and Reauthorization Ac
(SARA) water priority chemicals: and storage in any amount of hazardous substances, in
order to prevent leaks and spills from contaminating stormwater runoff. A table or
summary of all such tanks and stored materials and their associated secondary containment
areas shall be maintained. If the secondary containment devices are connected to
stormwater conveyance systems, the connection shall be controlled by manually activated
valves or other similar devices which shall be secured closed with a locking mechanism.
Any stormwater that accumulates in the containment area shall be at a minimum visually
observed for color, foam, outfall staining, visible sheens, and dry weather flow, prior to
release of the accumulated stormwater. Accumulated stormwater shall be released if found
to be uncontaminated by any material. Records documenting the individual making the
observation, the description of the accumulated stormwater, and the date and time of the
release shall be kept for a period of five (5) years.
(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.
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 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.

Permit No. NCG030000
Preventative Maintenance and Good Housekeeping Program. A preventative maintenance
and good housekeeping program shall be developed and implemented. The program shall
address all stormwater control systems (if applicable), stormwater discharge outfalls, all on -site
and adjacent surface waters and wetlands, industrial activity areas (including material storage
areas, material handling areas, disposal areas, process areas, loading and unloading areas, and
haul roads), all drainage features and structures, and existing structural BMPs. The program
shall establish schedules of inspections, maintenance, and housekeeping activities of
stormwater control systems, as well as facility equipment, facility areas, and facility systems
that present a potential for stormwater exposure 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 [I B, C, and D of this permit.
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 person(s) or position(s) responsible for
the overall coordination, development, implementation, and revision of the SPPP.
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);
(h) a written re-certffication that the stormwater outfalls have been evaluated for the
presence of non-stormwater discharges (element of the Site Overview);
(c) a documented re-evaluation of the effectiveness of the on -site stormwater BMPs
(BMP Summary element of the Stormwater Management Strategy).
(d) a statement that annual training requirements were met in the year past;
(e) a review and comparison of sample analytical data 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
(I)MR) form, available from the Stormwater Permitting Unit's website (See
'Monitoring Forms' here: http://liortal.ncdenr.org/web/wqlws/su/npdessw).

The Director may notify the permittee when the SPPP does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall submit
a time schedule to the Director for modifying the SPPP to meet minimum requirements. The
permittee shall provide certification in writing (in accordance with Part 111, Standard
Conditions, Section B, Paragraph 3) to the Director that the changes have been made.
SPPP Implementation. The permittee shall implement the Stormwater Pollution Prevention
Plan and all appropriate BMPs to prevent contaminants from 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 (S) years and made available to the Director or the Director's
authorized representative immediately upon request.
10. Solvent Management Plan. Facilities that implement a Solvent Management Plan may so
certify, and the requirement for Total Toxic Organics (TTO) monitoring in Part 11, Section B.
may be waived. The Solvent Management Plan shall include:
(a) an annually updated and quantified inventory of the total toxic organic compounds
present on site during the previous three years;
(b) a narrative description of the in -plant locations and uses of the toxic organic
compounds, the method of disposal including quantities disposed on- and off -site;
(c) the management procedures and engineering measures for assuring that toxic
organics do not spill or leak into stormwater.
DWQ may at its discretion require submittal, review, and approval of the Solvent Management
Plan as a condition of continuing the TTO sampling waiver. For those facilities electing to
employ the TTO sampling waiver, the permittee shall include the following signed certification
statement on each discharge monitoring report: "Based upon my inquiry of the person or persons
directly responsible for managing compliance with the permit monitoring requirement for total
toxic organics (TTO), I certify that to the best of my knowledge and belief, no leak, spill, or
dumping of concentrated toxic organics into the stormwater or onto areas which are exposed to
rainfall or storm water runoff has occurred since filing the last discharge monitoring report. 1
further certify that this facility is implementing all the provisions of the Solvent Management Plan
included in the Stormwater Pollution Prevention Plan."

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a measureable storm event at each stormwater
discharge outfall (SDO). Only SDOs discharging stormwater associated with industrial activity must
be sampled (See Definitions).
A measurable storm event is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office. See Definitions.

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 letter granting ROS shall be kept on site.
4 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations,
manufacture semiconductors, manufacture electronic crystals, or manufacture cathode ray tubes. For purposes of this
permit the definition of Total Toxic Organics is that definition contained in the EPA Effluent Guidelines for the
facility subject to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.1 1, for
semiconductor manufacture use the definition as found in 40 CFR 469.12; for electronic crystal manufacture use the
definition as found in 40 CFR 469.22; and for cathode ray tube manufacture use the definition found in
40 CFR 469.31.)
5 For each sampled measureable storm event, the total precipitation must be recorded. An on -site rain gauge
or local rain gauge reading must be recorded. 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). A minimum of 60 days must separate Period 1 and Period 2 sample
dates, bnless monthly monitoring has been instituted as part of other requirements of this permit.
Inability to sample because of adverse weather conditions must he documented in the SPPP and
recorded on the DMR. The permittee must report the results from each sample taken within the
monitoring period (see Part III, Section E).

Footnotes:
1 Maintain semi-annual analytical monitoring throughout the permit renewal process (unless other
provisions of this permit prompt monthly sampling).
2 If no discharge occurs during the sampling period, the permittee must submit a monitoring report
indicating "Ne Flow" or "No Discharge" within 30 days of the end of the sampling period.
Failure to monitor semi-annually per permit terms may result in the Division requiring monthly
monitoring for all parameters for a specified time period. "No discharge" from an outfall or
inability to collect a sampie because of adverse weather conditions during a monitoring period, for
example does not constitute failure to monitor, as long as it is properly reported.
The permittee shall compare monitoring results to the benchmark values in Table 3. The benchmark
values in Table 3 are not permit limits but should be used as guidelines for the implementation of the
permittee's Stormwater Pollution Prevention Plan (SPPP). 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. In the event that DWQ releases the permittee
from continued monthly monitoring under Tier Three, DWQ's release letter remains in effect through
the subsequent reissuance of this permit, unless the release letter provides for other conditions or
duration.

1 Measurement Frequency: Twice per year during a measureable storm event, until either another permit
is issued for this facility or until this permit is revoked or rescinded. See Table 2 for schedule of
monitoring periods through the end of this permitting cycle.
2 Grab samples shall be collected within the first 30 minutes of discharge.
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.
4 For each sampled measureable storm event the total precipitation must be recorded. An on -site or local
rain gauge reading must be recorded. Where isolated sites are unmanned for extended periods of time, a
local rain gauge reading may be substituted for an on -site reading.
Failure to monitor semi-annually per permit terms may result in the Division requiring monthly
monitoring for all parameters for a specified time period, as provided in Part II Section B.
Monitoring results shall be compared to the benchmark values in Table 5. The benchmark values
in Table 5 are not permit limits but should be used as guidelines for the permittee's Stormwater

SECTION D: QUALITATIVE MONITORING REQUIREMENTS
Permit No. NCG030000
The purpose of qualitative monitoring is to evaluate the effectiveness of the permittee's
implementation of the SPPP and to assess new sources of stormwater pollution. Qualitative
monitoring of stormwater outfalls must be performed during a measurable storm event.
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status. Qualitative monitoring shall be performed semi-annually as specified
in Table 6 and concurrent with the required analytical monitoring events (unless the permittee is
required to perform further qualitative sampling per the Qualitative Monitoring Response,
below). Inability to sample because of adverse weather conditions must be documented in the SPPP.
Only SDOs discharging stormwater associated with Industrial activity must be monitored (See
Definitions).

of monitoring periods through the end of this permitting cycle. The permittee must continue qualitative
monitoring throughout the permit renewal process.
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 dates, unless additional sampling has been
Instituted as part of other analytical monitoring requirements in this permit.
In the event an atypical condition is noted at a stormwater discharge outfall, the permittee shall
document the suspected cause of the condition and any actions taken in response to the discovery.
This documentation shall be maintained with the SPPP.

Permit No. NCG030000
If the permittee's qualitative monitoring indicates that existing stormwater BMPs are ineffective, or that
significant stormwater contamination is present, the permittee shall investigate potential causes, evaluate
the feasibility of corrective actions, and implement those corrective actions within 60 days, per the
Qualitative Monitoring Response, below. A written record of the permittee's investigation, evaluation,
and response actions shall be kept in the SPPP.
ve Monitorin
Qualitative monitoring is for the purposes of evaluating the effectiveness of the perjittee's
implenetaion of the SPPP, and for assessing new sources of stormwater pollution, and for 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, DWQ may but is not limited to:
• require that the permittee revise, increase, or decrease monitoring frequency for some or
all parameters (analytical or qualitative);
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures;
• require the permittee to perform upstream and downstream monitoring to characterize
impacts on receiving waters; or
• require the permittee implement site modifications to qualify for a No Exposure Exclusion.

Need to Halt or Reduce Not a Defense
It shall not be a defense for a permittee in an enforcement action that it would have been necessary
to halt or reduce the permitted activity in order to maintain compliance with the condition of this
general permit [40 CFR 122.41(c)].
Bypassing of Stormwater Control Facilities
Bypass is prohibited and the Director may take enforcement action against a permittee for bypass
unless:
a. Bypass was unavoidable to prevent loss of life, personal injury or severe property damage; and
b. There were no feasible alternatives to the bypass, such as the use of auxiliary control facilities,
retention of stormwater or maintenance during normal periods of equipment downtime or dry
weather. This condition is not satisfied if adequate backup controls should have been installed in
the exercise of reasonable engineering judgment to prevent a bypass which occurred during
normal periods of equipment downtime or preventive maintenance; and
c. The permittee submitted notices as required under, Part HI, Section E of this general permit.
If the Director determines that it will meet the three conditions listed above, the Director may
approve an anticipated bypass after considering its adverse effects.
SECTION D: MONITORING AND RECORDS
Representative Sam_plin
Samples collected and measurements taken, as required herein, shall be characteristic of the volume
and nature of the permitted discharge. Analytical sampling shall be performed during a measureable
storm event. 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
water, or substance. Monitoring points as specified in this general permit shall not be changed
without notification to and approval of the Permit Issuing Authority [40 CFR 122.41(j)].

To meet the intent of the monitoring required by this general permit, all test procedures must
produce minimum detection and reporting levels and all data generated must be reported down to
the minimum detection or lower reporting level of the procedure. If no approved methods are
determined capable of achieving minimum detection and reporting levels below general permit
discharge requirements, then the most sensitive (method with the lowest possible detection and
reporting level) approved method must be used.
S. 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

Technical Bulletin for N.C. General Stormwater
Y Permits NCG030000 and NCG090000
Technical Bulletin for NCG030000 and NCG090000 Last Revised 10/25/2012
What is regulated by these two General Permits?
These two General Permits regulate stormwater discharges from two groups of industrial manufacturing ac-
tivities:
-NCG030000 (NCG03) for metal fabrication and metal finishing businesses
✓NCG090000 (NCG09) for the manufacture of paints, varnishes, and allied products
What does my permit require me to do?
✓ Develop and implement a written Stormwater Pollution Prevention Plan (SPPP) (Part 11, Section A).
✓Provide secondary containment for bulk storage of liquid materials (Part 1l, Section A).
✓Conduct semi-annual self -monitoring of the pollutant content in stormwater discharges, and report the results to
DWQ (Part 11, Sections B and Q.
-Conduct semi-annual visual inspections of stormwater pollutant sources, control measures, conveyances, and out -
falls (Part it, Sections A and D).
-"Respond to monitoring results that exceed the numerical benchmarks with management actions to reduce the
level of pollutants in the stormwater discharges. The numerical benchmarks are considered as 'action levels.'
Why?
1 /The two General Permits seek to reduce industrial pollution in rainfall runoff from manufacturing businesses by
requiring site managers to be aware of, and control, the potential for polluted runoff.
✓Federal and state laws and regulations require the control of industrial pollution in stormwater runoff.
✓Those laws and regulations reflect the public's support for providing for clean natural waters in our state and
nation.
What has changed since the last renewals in 2007?
Common changes to both General Permits:
. The required content of the SPPP has been expanded slightly and clarified in minor ways in several paragraphs.
i. The permittee may now sample discharges from any measureable storm event, rather than from a representative
event. This change should make it easier to obtain a sample from a qualifying rain event.
. The permit text now clarifies that failure to sample due to adverse weather, or due to no discharge during the nor-
mal monitoring period, may be excused. However, the permits now require additional monthly monitoring for un-
excused failures to monitor.
�. Vehicle Maintenance Areas (VMA) shall be monitored for Total Petroleum Hydrocarbons (TPH) rather than Oil &
Grease (O&G).
• VMA monitoring is now triggered by the total oil usage for motor oil plus hydraulic oil. The trigger remains at a total
of 55 gallons per month, average.
• A lower TSS benchmark of 50 mg/L applies for discharges to especially protected water classifications.
Significant changes specific to the different General Permits
• For NCG03: Analytical monitoring for copper and zinc have been added to allow more facilities to qualify for cover-
age under this General Permit.
. For NCG09: Monitoring results must be reported in mg/L rather than ug/L; monitoring results may not be reported
as 'non -detect', or 'below detection limit', or other similar notations, but instead must indicate the numerical value
i of the reporting or detection limit of the test procedure employed.

Frequently Asked Questions
Do I have to monitor all outfalls?
Yes. However, you may request ROS
(Representative Outfall Status). If ROS is
approved, this status allows analytical
monitoring at fewer outfalls. To request
ROS, submit a ROS Request Form SWU-
ROS (from our website) to the DWQ
Regional Office.
What if I can't collect a storm -
water discharge in 30 minutes?
When distances separate multiple out -
falls and preclude collection within 30
minutes of each discharge event, begin
collection within 30 minutes and then
continue until all outfalls are sampled.
Documentation must be kept in the
SPPP.
Can I take more samples than
is required by my permit?
Yes. The permittee may take multiple
samples at any time while under permit
coverage. The permittee may find the
extra sampling useful to quickly identify
causes of benchmark exceedances. All
sampling for the permit parameters
must be reported to DWQ on the DMR
forms.
What if I can't sample because
of bad weather?
Adverse weather is dangerous or it may
limit access for sampling personnel.
Your documentation of adverse weather
and the reasons for not sampling must
be included in your SPPP. A substitute
sample may be taken during the next
qualifying storm event.
What if I don't address visual
monitoring problems?
If you do not respond to problems seen
in visual monitoring, DWQ may require
that you increase the visual monitoring
frequency, apply for an individual per-
mit, implement in -stream monitoring,
install or modify structural stormwater
controls, or implement other controls.
Why did you replace Oil &
Grease with TPH in VM areas?
The TPH test only targets chemicals de-
rived from crude oil. The Oil & Grease
(O&G) test recovers fats from animal &
vegetable sources and chemicals from
crude oil. Because TPH is more specific,
it is a better parameter for vehicle main-
tenance areas. The TPH method we are
specifying is EPA 1664A (SGT-HEM). It is
important to note that DWQ is not speci-
fying the more expensive Gas Chromoto-
graph (GQ TPH method. DWQ found lab
costs for EPA 1664A (SGT-HEM) to be
comparable to O&G test costs, To test
these parameters in stormwoter, labs
must perform this test in accordance
with EPA procedures, but do not need to
be certified. Note: A lower benchmark
applies for TPH: 15 mg/I (not 30 mg/1).
Why are there two benchmark
values for TSS?
The 100 mg/L benchmark applies to
most rivers, lakes, and creeks in North
Carolina. However, some other waters
must receive special protection under
North Carolina water quality rules, and
in these two permits discharges to them
are subject to the more protective
benchmark of 50 mg/L. Those waters
classified as Trout Waters, High Quality
Waters, Outstanding Resource Waters,
and Primary Nursery Areas receive this
extra protection in these permits.
Where and when do I send the
monitoring reports?
See your permit text, Part 1/1, Section E.
Who can help me?
Division of Water Quality (DWQ) Offices:
Must I use a North Carolina
certified laboratory?
No. North Carolina water quality rules
do not require that analyses of storm -
water be accomplished by a certified
facility. Please note however, federal
rules at 40CFR136 do require that test-
ing for these two permits be by EPA -
approved lab methods, Analysis by a
North Carolina certified lab is often the
easiest way to insure compliance with
federal rules.
Note that pH is a special case, and
must be measured within 15 minutes
of the sample recovery. You must ei-
ther train on -site staff to conduct pH
testing, or contract with commercial
services to test pH in accordance with
EPA field testing methods.
Must a P. E. sign and stamp my
SPPP?
No. North Carolina water quality rules do
not require that the SPPP be the work
product of a North Carolina P.E.
Who inspects me, and for what?
Staff from the DWQ Regional Offices
shown below will inspect your facility.
They will typically ask to see your SPPP
and will check to see if it is complete and
up to date. They will typically ask to see
your recent monitoring results. They will
typically tour the facility with a focus on
the stormwater discharge outfalls and on
your general housekeeping as a way to
assess the potential for polluted storm -
water discharges. Our staff will always
follow up their Compliance Evaluation
Inspection with a summary letter to you,
restating their findings and, if necessary
indicating whether enforcement action
will be considered in response to those
findings.

❖ Tier TWO - If sampling results are above benchmark value for two consecutive
monitoring periods:
• Repeat all required actions outlined in Tier One
- Immediately institute monthly monitoring for all parameters.
- Conduct Monthly monitoring at every outfall that exceeded the benchmark value
for two consecutive samples
- Monthly monitoring shall continue until three (3) consecutive samples are
below the benchmark values or within benchmark range.
- Submit a monthly monitoring report indicating "No Flow" if no discharge occurs
during the sampling period.
- Benchmark exceedances for a different parameter separately trigger a tiered
response.
- Maintain a record of the Tier II response and monitoring results in the SPPP.
