Subject: Draft NPDES Stormwater Permit
Permit No. NCS000255
Grede II, LLC
Montgomery County
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please
review the draft carefully to ensure thorough understanding of the conditions and
requirements it contains.
The draft permit contains the following significant changes from the facility's current permit:
1. You are required to collect analytical and qualitative monitoring samples during
"measurable storm events" as defined in Part II, Section B. This term is different
from the "representative storm event" in earlier permits.
2. Requirements for the Stormwater Pollution Plan (SPPP) have been updated in Part II,
Section A.
3, Changes have been made to three monitoring parameters, including changes to two
benchmarks. Stormwater benchmarks are not permit limits, but rather guidelines for
implementing the Stormwater Pollution Prevention Plan (SPPP). A benchmark
exceedance is not a permit violation; however, the permittee must respond to
exceedances as directed in the Tiers.
Non -polar Oil & Grease [EPA Method.1664 (SGT-HEM)] replaces Oil &
Grease to better represent potential discharges at a facility storing only
petroleum -based fuel oils (as opposed to non -petroleum -based fuel oils). The
benchmark for Non -polar Oil & Grease using this method is 15 mg/L.
• Monitoring for Zinc has been removed from your permit because this
constituent is not used in this facility's industrial processes.
State of Noah Carolina I Environmental Quality I Energy, Mineral and Land Resources
1612 Mail Service Center' 512 North Salisbury Street I Raleigh, NC 27699-1612
919 707 9200 T

+ Monitoring for Total Kjeldahl Nitrogen has been removed from your permit
because in multiple years of monitoring, levels have been consistently well
below the benchmark.
• The benchmarks for the following parameters have been revised to reflect
current water quality standards:
o Copper benchmark is increased from .007 mg/L to .010 mg/L;
o Cadmium benchmark is increased from .001 mg/L to .003 mg/L;
o Lead benchmark is increased from .03 mg/L to .075 mg/L; and
o Nickel benchmark is increased from .26 mg/L to .335 mg/L.
• Vehicle maintenance (Tables 5,6) monitoring parameters have been revised
as follows:
o Non -Polar Oil & Grease [EPA Method 1664 (SGT-HEM)] replaces
Oil & Grease/TPH. This requirement appears in all individual
stormwater permits; however, it only applies to facilities that
perform onsite vehicle maintenance activities. If the facility begins
vehicle maintenance during the permit cycle, the requirements shall
apply.
o pH monitoring is no longer required for discharges only associated
with vehicle maintenance activities.
4. Tiered responses have been added to this permit. Exceedances of benchmark values
require the permittee to increase monitoring, increase management actions, increase
record keeping, and/or install stormwater Best Management Practices (BMPs) in a
tiered program in accordance with Part II, Section B of this permit.
5. A new section on Special Conditions has been added in Part II, Section E to comply
with federal regulations requiring electronic submittal of discharge monitoring
reports. This section of the permit became effective December 21, 2016.
6. Civil and administrative penalty 'amounts have been updated to reflect current
federal law in Part III, Section A, 2(b) and (g).
7. Representative Outfall Status has not been granted for this facility. As such, you
must perform the required analytical monitoring at all Stormwater Discharge Outfalls
(SDO). Previous inspections by DEQ staff indicated that SDO #2 was not being
monitored and that SDO #3 (alleyway) was being used to represent SDO#2. Unless
DEQ staff grants approval of Representative Outfall Status, you must monitor all
SDOs, including SDO#2. In addition, note that qualitative monitoring shall continue
to be required at all SDOs, even if Representative Outfall Status is granted in the
future.
8. The following laboratory data reporting issues must be addressed:

1612Mm7ServiceG6la 1 512NDrihSa%bWSheet I Rakigt.NC276MI612
919707 MOD T

• Lab reports submitted to DEQ have erroneously labeled SDO#3 (alleyway) as
SDO#2. Please refer to the facility site map for proper identification of each
SDO.
• Lab results for phenols have been reported in the incorrect units. Please
ensure that lab results for all parameters are reported in the units specified in
the permit (mg/Q.
• For cadmium, the reported minimum detection limit appears to be above the
benchmark. Please ensure that the laboratory's minimum detection limit for
cadmium and all other parameters.are at or below the benchmarks specified in
the permit.
Please review the draft permit and submit any comments to me no later than 30 days
following your receipt of the draft. Comments may be emailed to me at
[e-mail] or mailed to my attention at NC DEMLR, Stormwater
Permitting Program, 1612 Mail Service Center, Raleigh, NC 27699-1612. If you have any
questions, please email me or call me at [phone].

fully compliant with the requirements of this permit may be used to demonstrate
compliance with this permit.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMPs) shall be provided. The installation and implementation of BMPs
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and on data collected
through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMP Summary shall be reviewed and updated annually.
Part II Page 2 of 15

Permit No. NCS000255
3. Spill Prevention and Response Procedures. The Spill Prevention and Response
Procedures (SPRP) shall incorporate an assessment of potential pollutant sources based
on a materials inventory of the facility. Facility personnel responsible for implementing
the SPRP shall be identified in a written list incorporated into the SPRP and signed and
dated by each individual acknowledging their responsibilities for the plan. A
responsible person shall be on -site at all times during facility operations that have
increased potential to contaminate stormwater runoff through spills or exposure of
materials associated with the facility operations. The SPRP must be site stormwater
specific. Therefore, an oil Spill Prevention Control and Countermeasure plan (SPCC)
may be a component of the SPRP, but may not be sufficient to completely address the
stormwater aspects of the SPRP. The common elements of the SPCC with the SPRP may
be incorporated by reference into the SPRP.
4. Preventative Maintenance and Good House eepi g:PrograA. A preventative
maintenance and good housekeeping program shall be developed and implemented.
.,..r N
The program shall address all stormwater cont .d' kt:systems (if applicable), stormwater
discharge outfalls, all on -site and adjacent surface wat rs and wetlands, industrial
activity areas (including material storage/area mat ial handling areas, disposal areas,
process areas, loading and unloading ar�eas,and)haul roads), all drainage features and
structures, and existing structural B Ps. /� eq rogram shall establish schedules of
P
ins ections, maintenance, tid housekeep'ing,activities of stormwater control systems,
as well as facility equipment''facility eas, and facility systems that present a potential
for stormwater exposure ofstomw`ter pollution where not already addressed under
another element of the SPPP. Inspection of material handling areas and regular
cleaning schedules of these arear6l be incorporated into the program. Timely
compliance with the es6blished'schedules for inspections, maintenance, and
housekeeping shall be ecbrded 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 11 B, C, and D of this
permit.
6. Employee Training. Training programs shall be developed and training provided at a
minimum on an annual basis for facility personnel with responsibilities for: spill
response and cleanup, preventative maintenance activities, and for any of the facility's
operations that have the potential to contaminate stormwater runoff. The facility
personnel responsible for implementing the training shall be identified, and their
annual training shall be documented by the signature of each employee trained.
7. Responsible Party. The SPPP shall identify a specific position or positions responsible
for the overall coordination, development, implementation, and revision of the SPPP.
Part II Page 3 of 15

Permit No. NCS000255
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 ofsignificant spills or leaks of pollutants for the previous three
(3) years, or the notation that no spills have occurred (element of the Site
Overview); A

Part III, Standard Conditions, Section B, Paragraph 3) to the Director that the changes
have been made.
9. SPPP Implementation. The permittee shall implement the Stormwater Pollution
Prevention Plan and all appropriate BMPs consistent with the provisions of this permit,
in order to control contaminants entering surface waters via stormwater.
Implementation of the SPPP shall include documentation of all monitoring,
measurements, inspections, maintenance activities, and training provided to
employees, including the log of the sampling data and of actions taken to implement
BMPs associated with the industrial activities, including vehicle maintenance activities.
Such documentation shall be kept on -site for a period of five (5) years and made
available to the Director or the Director's authorized representative immediately upon

All analytical monitoring shall be performed during a measureable storm event at each
Part 11 Page 4 of 15

Permit No. NCS000255
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
ermittee obtains approval from the local DEMLR Regional Engineer. See Definitions.

Permit No. NCS000255
The permittee shall complete the analytical samplings in accordance with the schedule
specified below in Table 2, unless adverse weather conditions prevent sample collection
(see Adverse Weather in Definitions). Sampling is not required outside of the facility's
normal operating hours. A minimum of 60 days must separate Period 1 and Period 2
sample dates, unless monthly monitoring has been instituted under a "Tier Two"
response. Inability to sample because of adverse weather conditions must be documented
in the SPPP and recorded on the DMR. The permittee must report the results from each
sample taken within the monitoring period (see Part 111, Section E). However, for purposes
of benchmark comparison and Tiered response actions, the permittee shall use the
analytical results from the first sample with valid results within the monitoring period.

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

While you're pondering that question, could you also take a look at the attached draft permit and cover letter? In the
interest of trying to catch up on our permit backlog, I'm using the cover letter as my staff report. I've put in a few
comments where I'd like your feedback in particular.
Do you think you (or someone else at FRO) will want to do a site visit before I send the draft to the permittee? There are
some issues I point out in the cover letter that are really more compliance issues, not permit renewal issues per se.
Thanks!

Permit No. NCS000255
Grede I1, LLC
Montgomery County
Dear Mr. xxz:
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please
review the draft carefully to ensure thorough understanding of the conditions and
requirements it contains.
The draft permit contains the following significant changes from the facility's current permit:
I. You are required to collect analytical and qualitative monitoring samples during }
"measurable storm events" as defined in Part,[[, Section B. This term is different l
from the "representative storm event" in earlier permits.
2. Requirements for the Stormwater Pollution Plan (SPPP) have been updated in Part II,
Section A.
3. Changes have been made to three monitoring parameters, including changes to two
benchmarks. Stormwater benchmarks are not permit limits, but rather guidelines for
implementing the Stormwater Pollution Prevention Plan (SPPP). A benchmark i
exceedance is not a permit violation; however, the permittee must respond to
exceedances as directed in the Tiers.
r Non -polar Oil & Grease [EPA Method 1664 (SGT-HEM)] replaces Oil &
Grease to better represent potential discharges at a facility storing only
petroleum -based fuel oils (as opposed to non -petroleum -based fuel oils). The
benchmark for Non -polar Oil & Grease using this method is 15 mglL.
Monitoring for Copper, Zinc, and Total KJeldahl Nitrogen have been
removed from your permit because these constituents are not present in '
significant amounts in this facility's industrial processW

Commented VV3I: Will confirm this is the case whim I
get in touch with the facility. Not atm why TKN was
included k1 the first place. Also aced to discuss with
Bethany since t sec in old staff report that copper and zinc
might be required by the "B.PA Sector -Specific permit"?
Commented [1.144143I: I agree with removal of these
parameters IF they arc not part of their industrial prpcessea
and we don't have to include them pei• some EPA' `
requirement. .... .

• The benchmarks for the following parameters have been revised to reflect
current water quality standards:
o Cadmium benchmark is increased from .001 mg/L to .003 mg/L;
o Lead benchmark is increased from .03 mg/L to .075 mg/L; and
o Nickel benchmark is increased from .26 mg/L to .335 mg/L.
• Vehicle maintenance (Tables 5,6) monitoring parameters have been revised
as follows:
o Non -Polar Oil & Grease [EPA Method 1664 (SGT-HEM)] replaces
Oil & Grease/TPH. This requirement appears in all individual
stormwater permits; however, it only applies to facilities that
perform onsite vehicle maintenance activities. If the facility begins
vehicle maintenance during the permit cycle, the requirements shall
apply.
o pH monitoring is no longer required for discharges only associated
with vehicle maintenance activities.
4. Tiered responses have been added to this permit. Exceedances of benchmark values
require the permittee to increase monitoring, increase management actions, increase
record keeping, and/or install stormwater Best Management Practices (BMPs) in a
tiered program in accordance with Part 11, Section B of this permit.
5. A new section on Special Conditions has been added in Part 11, Section E to comply
with federal regulations requiring electronic submittal of discharge monitoring
reports. This section of the permit will l?e o'=4,effective December 2l, 2016.
6. Civil and administrative penalty amounts have been updated to reflect current
federal law in Part 111, Section A, 2(b) and (g).
7. Rep"entatiVcF0ut&HTStatnU as not been grartted for this facility As such, you_
must perform the required analytical monitoring at all Stormwater Discharge Outfalls
(SDO). Previous inspections by DEQ staff indicated that SDO #2 was not being
monitored and that SDO #3 (alleyway) was being used to represent SDO#2. Unless
DEQ staff grants approval of Representative Outfall Status, you must monitor all
SDOs, including SDO#2. In addition, note that qualitative monitoring shall continue
to be required at all SDOs, even if Representative Outfall Status is granted in the
future.
8. The following laboratory data reporting issues must be addressed:
• Lab reports submitted to DEQ have erroneously labeled SDO#3 (alleyway) as
SDO#2. Please refer to the facility site map for proper identification of each
SDO.

• Lab results for phenols have been reported in the incorrect units. Please i
ensure that lab results for all parameters are reported in the units specified in
the permit (mg/L).
• For cadmium, the reported minimum detection limit appears to be above the
benchmark. Please ensure that the laboratory's minimum detection limit for
cadmium and all other parameters are at or below the benchmarks specified in
the permit. i

Subject: Renewal of Grede's NPDES stormwater permit
Mr. Jackson,
I left you a voicemail, but I also wanted to follow up with you by email. I am working the renewal of Grede II's NPDES
stormwater permit renewal (Permit No. NCS000255). As you're probably aware, the permit for this facility expired in
2012, but it has continued to remain in effect since the facility applied for renewal as required. We're finally starting to
make some headway on getting through our backlog of expired permits, and I'm working on yours now. In order to
move forward, I need some information from you:
1. Our database shows Richard Cabadas as the person primarily responsible for the permit. I've been told he no
longer works at this facility. Would you please complete our "Permit owner affiliation designation form" with
the current information so that we can update our database?
Attached is the signed Permit Affiliation Designation Form
2. Could you please send me the past 5 years of monitoring data from all your stormwater discharge outfalls?
QL See attachments Awe
3. We are moving towards an electronic system of collecting monitoring data. For that purpose, would you please
send me lat/long coordinators for each of your outfalls? I believe you had 3 outfalls as of 2012.

4. As part of our renewal process, I'm looking at whether any monitoring parameters should be added or dropped
from the permit. Your current (expired) permit requires that stormwater be tested for copper and zinc. Can you
please tell me if you use copper and zinc in your industrial processes?

Copper is added to the pouring ladles while iron is being transferred from the large bull ladles to create . Zinc is not used
in the process.
I'm copying Tiffany Lambert with Willoughby & Associates on this email. It's my understanding she is assisting the
facility with permitting -related issues.
Once I get this additional information, I'll finish writing up the new draft permit and send it on to you for
review. Someone from our Fayetteville Regional Office will also be in touch to schedule a site visit.

Commented IJVI]: Mike L — Any idea who I can get to
call me back from Grede?
Commented [LM2R1]: Refer to a -mail from Tiffany
Lambert with Willoughby Associates (consultant) that I
forwarded to you.
1, You are required to collect analytical and qualitative monitoring samples during
"measurable storm events" as defined in Part II, Section B. This term is different
from the "representative storm event" in earlier permits.
2. Requirements for the Stormwater Pollution Plan (SPPP) have been updated in Part II,
Section A.
3. Changes have been made to three monitoring parameters,. including changes to two
benchmarks. Stormwater benchmarks are not permit limits, but rather guidelines for
implementing the Stormwater Pollution Prevention Plan (SPPP). A benchmark
exceedance is not a permit violation; however, the permittee must respond to

exceedances as directed in the Tiers.

• The benchmarks for the following parameters have been revised to reflect
current water quality standards:
o Cadmium benchmark is increased from .001 mg/L to .003 mg/L;
o Lead benchmark is increased from .03 mg/L to .075 mg/L; and
o Nickel benchmark is increased from .26 mg/L to .335 mg&
• Vehicle maintenance (Tables 5,6) monitoring parameters have been revised
as follows:
o Non -Polar Oil & Grease [EPA Method 1664 (SGT-HEM)] replaces
Oil & Grease/TPH. This requirement appears in all individual
stormwater permits; however, it only applies to facilities that
perform onsite vehicle maintenance activities. If the facility begins
vehicle maintenance during the permit cycle, the requirements shall
apply.
o pH monitoring is no longer required for discharges only associated
with vehicle maintenance activities.
4. Tiered responses have been added to this permit. Exceedances of benchmark values
require the permittee to increase monitoring, increase management actions, increase
record keeping, and/or install stormwater Best Management Practices (BMPS) in a
tiered program in accordance with Part 11, Section B of this permit.
5. A new section on Special Conditions has been added in Part II, Section E to comply
with federal regulations requiring electronic submittal of discharge monitoring
reports. This section of the permit [will become'effective December 21, 20 16 .
6. Civil and administrative penalty amounts have been updated to reflect current
federal law in Part III, Section A, 2(b) and (g).
Commented [LMS]: Change to'becarne' as we've already

future.
8. The following laboratory data reporting issues must be addressed:
• Lab reports submitted to DEQ have erroneously labeled SDO#3 (alleyway) as
SDO#2. Please refer to the facility site map for proper identification of each
SDO.

Lab results for phenols have been reported in the incorrect units. Please
ensure that lab results for all parameters are reported in the units specified in
the permit (mg/L).
For cadmium, the reported minimum detection limit appears to be above the
benchmark. Please ensure that the laboratory's minimum detection limit for

Thanks. And after we talked, I looked up nitrogen in foundries:
"Numerous sources of nitrogen exist during the melting, the ladle processing and the casting operations. Sources of
nitrogen in oxygen steelmaking include the hot metal, the scrap, the impurity nitrogen in oxygen and the nitrogen used
as a stirring gas."
I may still suggest eliminating nitrogen from the permit since they've been consistently below benchmarks.

Stormwater Discharge Outfall Visual Monitoring Summary
The visual monitoring reports have been consistent. All observations have been made at the discharge
from the storm drain collection pipe emptying into an unnamed tributary of Lily Creek.
Color:
The color has been described by observer as "medium black". This could mean the discharge appears to
be a dark gray in color.
Odor:
There has been no noticeable odor during any visual checks.
Clarity:
The discharge has been cloudy during most of the observations. On a scale of 1-10 with 1 being clear

II. Potential Pollutant Sources
Site map is attached indicating the drainage of the storm water outfall,
locations of exposed materials, fuel tanks, oil storage area, loading and
unloading areas, and chemical usage and storage areas. There have been
no significant spills or leaks to note on the map.

Materials exposed to precipitation:
• Temporary storage of spent foundry sand, slag, and other nonhazardous solid
wastes in one twenty yard open -top container behind foundry near Shipping (1)
• Baghouse dust from Grinding Room & foundry baghouses (1)
• Empty drums stored next to oil storage shed (2)
• Used oil and oily sand in drums outside of covered storage area on south end
of plant property (2)
• Former landfill site, now closed in accordance with NCDEHNR regulations,
Requiring post -closure maintenance to prevent sediment runoff (2)
(1) Primary potential pollutant is suspended solids
(2) Primary potential pollutant is oil or organic chemicals
Materials not exposed to precipitation that could contribute to pollutant
discharges from mishandling or misuse:
• Coremaking chemicals (resins & catalysts) in Core Room (3)
• Methyl formate located in room adjoining Core Room (3)
• Diesel fuel tank, 500 gallon capacity, located at oil storage area (3)
• Gasoline tank, 500 gallon capacity, located at oil storage area (3)
• Oils at oil storage shed — motor oil, gear oil, and hydraulic fluids (3)
• Used oils in drums in diked storage shed on south end of property (3)
• Pattern spray material (4)
• Scrap iron and steel (4)
(3) Moderate to slight risk of pollutant release
(4) Very slight risk of pollutant release
Activities with potential for pollutant release:
Forklift usage (5)
Emptying baghouses (6)
Handling drums of chemicals (5)
Transporting used oils to storage shed (5)
Air compressor blowdown from filter, receiver, and dryer (5)
Unloading drums at receiving dock (5)
Roof and roof exhausters (6)
Pallets with material spilled on them (5)
Cooling tower discharge (7)
(5) Oils or organic compounds
(6) Particulate matter could contribute to suspended solids released

(7) Non contact cooling water discharge not covered by this permit
Likelihood of contaminant releases:
• The diesel and gasoline fuel tanks pose a slight risk from a leaking tank,
damage to the tanks from forklifts, overfilling of trucks during fueling,
and spills during filling the tanks themselves. The fuel could reach the
storm water runoff ditch if the spill or leak occurs outside the diked area.
• Oil stored under the shed could be spilled into the runoff ditch from
overfilling containers, forklift damage, and mishandling of the drums.
This is only a slight risk due to the dike.
• The open -top bins used to collect nonhazardous solid wastes and the
dust removed from the baghouses pose a risk of contributing to the
suspended solids levels in the runoff. This is a slight risk due to the
discharge point and is inert.
• Unloading chemicals from trucks poses a slight risk from damaging
a drum or bulk tank of material with a forklift or from dropping the
container.
• The air compressor blowdown contains small amounts of oil that
could reach the runoff ditch and cause an oil sheen on water leaving
the property. This is a very slight risk.
• There are other slight risks of suspended solids releases including
Roof exhausters and blowing sand into the storage silo.
• The used oil kept in drums exposed to the weather are moderate
risks for pollutant discharges due to overfilling, damage, or improperly
sealing the drums.
III. Existing management measures to prevent pollutant releases
• Shed over diked oil and fuel storage area
• Landfill has an erosion control basin with spillway at the discharge point
• Coremaking chemicals (resins and methyl formate) stored in concrete
block building
• . Forklift maintenance performed indoors
• Raw materials stored under a roof
• Solid wastes placed directly into roll -off bins rather than a pile
• PM's performed on baghouses to reduce solids emissions
• Drums of in use chemicals stored on secondary containment pallets

Best management practices:
A. Good housekeeping
• Scheduled plant cleanup
• Drums of oil and fuel tanks stored under a diked shed
• Coremaking chemicals stored inside a building
• Roll off bins are used rather than waste piles
• Bulk bags are used to collect dust at the baghouses
• Scrap iron and steel kept under roof
• Housekeeping brought up as a topic at employee meetings
• Posters and signs around the plant stress good housekeeping
B. Preventive maintenance
• There are scheduled inspections of forklifts for leaks
• There are scheduled baghouse inspections
• The air compressors receive scheduled maintenance checks
to reduce the chances of oil leaks
C. Inspections
• Baghouse hoopers and bulk bags are inspected to prevent overfilling
• The oil storage area is checked to make sure no drums or tanks are
leaking, lids are in place, and valves are closed
• PCB capacitors are checked for swelling and leakage on a scheduled
basis
D. Spill prevention response
• A spill kit is kept on site
• Maintenance and operations personnel will respond to all spills
E. Sediment and erosion control
• Grass has been seeded on the landfill area, and a small erosion
basin is located at the discharge point
F. Management of runoff
• As much of the runoff as possible is routed to the grass covered ditch
leaving the property
G. Additional BMPN
IV. Employee training topics
• Hazard Communication Standard (Right -to -know law)
• Prooper handling and use of chemicals
• Proper disposal methods and locations of disposal staging areas
• Proper handling of drums — full and empty
• When and how to use the spill kit
• Where spill potential exists

• Basic water pollution laws
• Drum and container labeling
V. Employee training
• The Maintenance Manger has received instructions in the proper sampling
locations, sample collection procedures, pH meter operation, and necessary
recordkeeping. Recordkeeping includes test results, DMR's, sample container
labeling, chain -of -custody forms, and rainfall event information.
• All employees have received Hazardous Communication Standard training.
This is recorded in their personnel files.
• Employee are instructed in their individual departments of the proper handling
methods, precautions, and container labeling for the materials used in their
departments.
• All employees are instructed to inform their supervisors, or other plant
management personnel, of any spill, leaking container, or other potential source
of contaminant release.

History:
• 1 January 1995: First issued to Citation Corporation for Foundry Service Company, to Lick Creek
(class C) in the Yadkin -Pee Dee River Basin. This required annual monitoring for TSS, COD, Cu,
Zn, Cd, Pb, Ni, TKN, phenols, and used cutoff concentrations. Vehicle maintenance monitoring
was required for pH, oil and grease, Pb, TSS, and detergents containing methylene blue active
substances (MBAS).
• 1 March 2000: Re -issued requiring seven samples per cycle without cutoff concentrations.
Vehicle maintenance monitoring was required, but no MBAS or Pb.
• 3 December 2002: Corrected the River Basin from Yadkin -Pee Dee to Cape Fear. The receiving
stream classification was also corrected at this time (revised from C to WS-111). There is a Lick
Creek in the Yadkin River Basin that has a C classification, which may have been the source of the
original error.
• 6 August 2004: Renewal submitted.

Central Office Review Summary:
General Observations: This facility has not completed all of the requirements of the previous permit.
A site visit may be pertinent for this facility if one has not already been conducted recently.
Specifically, the analytical monitoring data shows excursions beyond the current benchmark values
and is incomplete, the permittee needs guidance on determining the locations of outfalls and needs
determination of representative outfall status, and the qualitative data is also of concern. Additionally,
the application references solid waste disposal dumpsters, which may contain oily metal scraps that
may contaminate the stormwater. The applicant -also notes that there is HAZMAT onsite., The site
plan shows that there is an illicit connection "to be removed" at CB#32, that CB#12 is "to be
plugged", and that "quench water was to be routed to SS" at CB#41. Were these actions taken? If not,
do they need to be? CB#41 also appears to have a source inside a building that discharges to a
stormwater ditch, but this is not specified as an outfall. There are used sand piles onsite. These piles
may contribute to TSS, and they may also have other contaminants. Do they?
2. Impairment: Lick Creek, is classified as WS-III. Lick Creek is not classified as impaired on the 303(d)
list. However, it drains to Cotton Creek, which is impaired for biological integrity. The Basinwide
Plan cites the Star WWTP as the source of the standard violations, not this facility.
3. Industrial Changes Since the Previous Permit: There have been no significant industrial changes to the
facility since the previous permit.

NCS000255
Analytical Monitoring Data:
As shown in Table 1, the permittee failed to submit all of the required analytical data. COD, copper,
zinc, and TSS are consistently high. Phenols, cadmium, lead, nickel, and total kjeldahl nitrogen have
been below the current benchmark for the samples provided. The permittee did not record rainfall
depth, rainfall duration, or flow volume data for the previous cycle. The permittee also failed to
sample both outfalIs throughout the previous permitting cycle.

Permit Changes: Analytical Monitoring:
1. pH has been added per DWQ revised strategy.
2. Oil and grease has been added because this facility likely uses oils as coolants and/or lubricants in the
machining process.
3. Due to a potential lag time between the expiration of this permit and its renewal, the reviewer has
specified in the permit that the permittee is responsible for all monitoring until the renewal permit is
issued. See Footnote 1 of Tables 1, 4, and 5. This approach is recommended because there has been a
significant lag time since the expiration of the previous cycle. This will provide testing if there is a lag
in future timeframes.
4. Benchmarks have been added to this draft permit.
5. All analytical monitoring has been set to semi-annually.
6. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall and
event duration parameters are in this permit, however.) '
7. The permittee is required to collect all of the analytical monitoring samples during representative storm
events as defined in this permit. This is not a change from their previous permit. Qualitative
monitoring does not have to be performed during a representative storm event.
8. The analytical monitoring required by the EPA Sector -Specific permit; copper, zinc, and total
suspended solids, were already included in the previous permit and are also included for the upcoming
permit cycle.
Permit Changes: Other Proposed Changes:
1. Part II Section A has been revised. It now specifies all of the items to include on the site map.
2.. Vehicle maintenance has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
3. The permittee is encouraged to use form SWU-242-020705 for qualitative monitoring reporting and
SWU-246-051100 for analytical monitoring required. The permittee is required to report all of the
information on these forms (or subsequent forms as amended).
0 4. 1 will inform the permittee in the cover letter of the permit that the minimum detection limits for all
analytical reporting requirements should be below the benchmarks specified in the permit.
5. The permittee states in their application that they have determined that SDO 002 can be represented by
SCO 001. 1 will point out to the permittee that they do not have the authority to make that
determination. The applicant has applied for representative outfall status for the upcoming cycle. If
there is a site visit, DWQ should determine whether or not to grant this status. The permittee reports
that SDO 002 drains less than 2% of the facility. However, this area is of considerable size (10,282
ftZ) and is also 90% impervious. We should consider "outfalls" as discharge points from the facility.
These are areas where flow leaves the property via pipes, trenches, gullies, swales, ditches, etc. Each
of these discharge points must be sampled unless DWQ grants representative outfall status. Also note
on the facility map that there may be more outfalls than just 001 and 002. For instance, does CB#42
leave the site? Others?
6. 1 will point out to the permittee that they are to report their data in the units specified in the permit
(mg/4

Subject: Draft NPDES Stormwater Permit
Permit No. NCS000255
Citation Castings, LLC
Montgomery County
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please review the draft
very carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from this facility's current permit:
• pH and oil and grease have been added for analytical monitoring.
•. All analytical monitoring has changed from annual to semi-annual (once in the spring and once
in the fall). This'change is based on the Division's revised strategy for stormwater monitoring in
renewal permits and makes stormwater discharge sampling frequency consistent with qualitative
monitoring. Please note that analytical monitoring must still be performed during a
representative storm event (whereas qualitative does not).
• . You are responsible for all monitoring until the renewal permit is issued. See Footnote 1 of
Tables 1, 4, and 5.
• Instead of "cut-off concentrations,",the Division has incorporated benchmark values into the
permit. These benchmarks are not permit limits but should be used as guidelines for your
facility's Stormwater Pollution Prevention Plan (SPPP). If any measurements exceed benchmark
values, your facility should evaluate the effectiveness of its Best Management Practices (BMPs),'
review and/or update its SPPP, and document any efforts to address stormwater contamination
(see Part II, Sections B and D). The minimum detection limits for each analytical parameter
should be low enough to detect the benchmark levels.
• Total Flow monitoring has been removed. The permit still requires Total Rainfall amount and
Rainfall Event Duration be recorded for each sampling event. This change is' also based on the
Division's revised strategy for stormwater monitoring in renewal permits. PIease note that the
Stormwater Pollution Prevention Plan (SPPP) site map must include drainage area for each
outfall in acres and the percentage of each drainage area that is impervious (see Part II, Sec. A).
Please submit any comments to me no later than thirty (30) days following your receipt of the draft.
Comments should be sent to the address listed at the bottom of this page. If no adverse comments are
received from the public or from you, this permit. will be issued in. approximately two months.

You are currently required to sample at two outfalls, SDO-001 and SCO-002. Your application shows that
you determined that SDO-002 could be represented by SDO-001. You should have consulted the
Division about this decision. If you would like to request representative outfall status to sample SDO-001
as representative of SDO-002 for the upcoming permit cycle, please do in writing and address the letter to
my attention. Please include a brief description as to why you believe that this is appropriate.

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 below in Table 4. Qualitative
monitoring is for the purpose of evaluating the effectiveness of the Stormwater Pollution
Prevention Plan (SPPP) and assessing new sources of stormwater pollution. No analytical tests
are required. Qualitative monitoring of stormwater outfalls is performed when stormwater
discharge occurs but does not need to be performed during a representative storm event.
In the event an atypical condition is noted at a stormwater discharge outfall, the Permittee shall
document the suspected cause of the condition and any actions taken in response to the
discovery. This documentation will be maintained with the Stormwater Pollution Prevention
Plan.
All qualitative monitoring will be performed twice per year, once in the spring (April - June) and
once in the fall (September - November).''"s,,

History:
• 1 January 1995: First issued to Citation Corporation for Foundry Service Company, to Lick Creek
(class C) in the Yadkin -Pee Dee River Basin. This required annual monitoring for TSS, COD, Cu,
Zn, Cd, Pb, Ni, TKN, phenols, and used cutoff concentrations. Vehicle maintenance monitoring .
was required for pH, oil and grease, Pb, TSS, and detergents containing methylene blue active
substances (MBAS).
• 1 March 2000: Re -issued requiring seven samples per cycle without cutoff concentrations.
Vehicle maintenance monitoring was required, but no MBAS or Pb.
• 3 December 2002: Corrected the River Basin from Yadkin -Pee Dee to Cape Fear. The receiving
stream classification was also corrected at this time (revised from C to WS-III). There is a Lick
Creek in the Yadkin River Basin that has a C classification, which may have been the source of the
original error.
• G August 2004: Renewal submitted.

NCS000255
Central Office Review Summary:
General Observations: This facility has not completed all of the requirements of the previous permit.
A site visit may be pertinent for this facility if one has not already been conducted recently,
Specifically, the analytical monitoring data shows excursions beyond the current benchmark values
and is incomplete, the permittee needs guidance on determining the locations of outfalls and needs
determination of representative outfall status, and the qualitative data is also of concern. Additionally,
the application references solid waste disposal dumpsters, which may contain oily metal scraps that
may contaminate the stormwater. The applicant also notes that there is HAZMAT onsite. The site
plan shows that there is an illicit connection "to be removed" at CB#32, that CB#12 is "to be
plugged", and that "quench water was to be routed to SS" at CB#41. Were these actions taken? If not,
do they need to be? CB#41 also appears to have a source inside a building that discharges to a
stormwater ditch, but this is not specified as an outfall. There are used sand piles onsite. These piles
may contribute to TSS, and they may also have other contaminants. Do they?
2. Impairment; Lick Creek, is classified as WS-I1I, Lick Creek is not classified as impaired on the 303(d)
list. However, it drains to Cotton Creek, which is impaired for biological integrity. The Basinwide
Plan cites the Star WWTP as the source of the standard violations, not this facility.
3. Industrial Changes Since the Previous Permit: There have been no significant industrial changes to the
facility since the previous permit.

.Analytical Monitoring Data:
As shown in Table 1, the permittee failed to submit all of the required analytical data. COD, copper,
zinc, and TSS are consistently high. Phenols, cadmium, lead, nickel, and total kjeldahl nitrogen have
been below the current benchmark for the samples provided. The permittee did not record rainfall
depth, rainfall duration, or flow volume data for the previous cycle. The permittee also failed to
sample both outfalls throughout the previous permitting cycle.

Permit Changes: Analytical Monitoring:
1. pH has been added per DWQ revised strategy.
2. Oil and grease has been added because this facility likely uses oils as coolants and/or lubricants in the
machining process.
3. Due to a potential lag time between the expiration of This permit and its renewal, the reviewer has
specified in the permit that the permittee is responsible for all monitoring until the renewal permit is
issued. See Footnote 1 of Tables 1, 4, and 5. This approach is recommended because there has been a
significant lag time since the expiration of the previous cycle. This will provide testing if there is a lag
in future timeframes.
4. Benchmarks have been added to this draft permit.
5. All analytical monitoring has been set to semi-annually.
6. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall and
event duration parameters are in this permit, however.)
7. The permittee is required to collect all of the analytical'monitoring samples during representative storm
events as defined in this permit. This is not a change from their previous permit. Qualitative
monitoring does not have to be performed during a representative storm event.
8. The analytical monitoring required by the EPA Sector -Specific permit; copper, zinc, and total
suspended solids, were already included in the previous permit and are also included for the upcoming
permit cycle.
Permit Changes: Other Proposed Changes:
I. Part 1I Section A has been revised. It now specifies all of the items to include on the site map.
2. Vehicle maintenance has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
3. The permittee is encouraged to use form SWU-242-020705 for qualitative monitoring reporting and
SWU-246-051100 for analytical monitoring required. The permittee is required to report all of the
information on these forms (or subsequent forms as amended).
4. I will inform the permittee in the cover letter of the permit that the minimum detection limits for all
analytical reporting requirements should be below the benchmarks specified in the permit.
5. The permittee states in their application that they have determined that SDO 002 can be represented by
SCO 001. I will point out to the permittee that they do not have the authority to make that
determination. The applicant has applied for representative outfall status for the upcoming cycle. If
there is a site visit, DWQ should determine whether or not to grant this status. The permittee reports
that SDO 002 drains less than 2% of the facility. However, this area is of considerable size (10,282
ftZ) and is also 90% impervious. We should consider "outfalls" as discharge points from the facility.
These are areas where flow leaves the property via pipes, trenches, gullies, swales, ditches, etc. Each
of these discharge points must -be sampled unless DWQ grants representative outfall status. Also note
on the facility map that there may be more o_utfalls than just 001 and 002. For instance, does CB#42
leave the site? Others?
6. I will point out to the permittee that they are to report their data in the units specified in the permit .
(mg/L,).

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 below in Table 4. Qualitative
monitoring is for the purpose of evaluating the effectiveness of the Stormwater Pollution
Prevention Plan (SPPP) and assessing new sources of stormwater pollution. No analytical tests
are required. Qualitative monitoring of stormwater outfalls is performed when stormwater
discharge occurs but does not need to be performed during a representative storm event.
In the event an atypical condition is noted at a stormwater discharge outfall, the Permittee shall
document the suspected cause of the condition and any actions taken in response to the
discovery. This documentation will be maintained with the SSttornwater Pollution Prevention
Plan.
All qualitative monitoring will be performed twice per ear on ein-the spring Aril - June and

Permit No. NCS000255
PART I
MONITORING, CONTROLS, AND LIMITATIONS FOR PERMITTED
' DISCHARGES
During the period beginning on the effective date of the permit and lasting until expiration, the
Permittee is authorized to discharge stonnwater associated with industrial activity. Such
discharges shall be controlled, limited and monitored as specified below.
Prevention-Man1—Stormwater Pollution
The Permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as the
Plan. This Plan shall be considered public information in accordance with Part H, Standard
Conditions, Section E.8. of this permit. The Plan shall include, at a minimum, the following
items:
a. Site Plan. The site plan shall provide a description of the physical facility and the potential
pollutant sources which may be expected to contribute to contamination of stormwater
discharges. The site plan shall contain the following:
(1) A general location map (USGS quadrangle map or appropriately drafted equivalent
map), showing the facility's location in relation to transportation routes and surface
waters, the name of the receiving water(s) to which the stormwater outfall(s)
discharges, or if the discharge is to a municipal separate storm sewer system, the
name of the municipality and the ultimate receiving waters; and accurate latitude
and longitude of the point(s) of discharge.
(2) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices.
(3) A site map drawn to scale with the distance legend indicating location of industrial
activities (including storage of materials, disposal areas, process areas and loading
and unloading areas), drainage structures, drainage areas for each outfall and
activities occurring in the drainage area, building locations and impervious surfaces,
and the percentage of each drainage area that is impervious. For each outfall, a
narrative description of the potential pollutants which could be expected to be
present in the stormwater discharge.
(4) A list of significant spills or leaks of pollutants that have occurred at the facility
during the 3 previous years and any corrective actions taken to mitigate spill
impacts.
(5) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The certification statement will be signed in
accordance with the requirements found in Part H, Standard Conditions, Section
B.9.
Page 4

Permit No. NCS000255
b. Stormwater Management Plan. The stormwater management plan shall contain a narrative
description of the materials management practices employed which control or minimize the
exposure of significant materials to stormwater, including structural and nonstructural
measures. The stormwater management plan, at a minimum, shall incorporate the
following:
(1) A study addressing the technical and economic feasibility of changing the methods
of operations and/or storage practices to eliminate or reduce exposure of materials
and processes to stormwater. Wherever practicable the permittee shall cover all
storage areas, material handling operations, manufacturing or fueling operations to
prevent materials exposure to stormwater. In areas where elimination of exposure
is not practicable, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
(2) A schedule to provide secondary containment for bulk storage of liquid materials,
storage of Section 313 of Title III of the Superfund Amendments and
Reauthorization Act (SARA) water priority chemicals, or storage of hazardous
materials to prevent leaks and spills from contaminating stormwater runoff. If the
secondary containment devices are connected directly to stormwater conveyance
systems, the connection shall be controlled by manually activated valves or other
similar devices [which shall be secured with a locking mechanism] and any
stormwater that accumulates in the containment area shall be at a minimum visually
observed for color, foam, and visible sheens, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated. Records documenting the individual making the observation, the
description of the accumulated stormwater and the date and time of the release shall
be kept for a period of five years.
(3) A narrative description shall be provided of Best Management Practices (BMPs) to
be considered such as, but not limited to; oil and grease separation, debris control,
vegetative filter strips, infiltration and stormwater detention or retention, where
necessary. The need for structural BMPs shall be based on the assessment of
potential of sources to contribute significant quantities of pollutants to stormwater
discharges and data collected through monitoring of stormwater discharges.
(4) Inspection schedules of stormwater conveyances and controls and measures to be
taken to limit or prevent erosion associated with the stormwater systems.
C. Spill Prevention and Response Plan. The Spill Prevention and Response Plan shall
incorporate a risk assessment of potential pollutant sources based on a materials inventory
of the facility. Facility personnel (or team) responsible for implementing the plan shall be
identified in the plan. A responsible person shall be on -site at all times during facility
operations that have the potential to contaminate stormwater runoff through spills or
exposure of materials associated with the facility operations.
d. Preventative Maintenance and Good Housekeeping Program. A preventative maintenance
program shall be developed. The program shall document schedules of inspections and
maintenance activities of stormwater control systems, plant equipment and systems.
Inspection of material handling areas and regular cleaning schedules of these areas shall be
incorporated into the program.
e. Employee Training. Training schedules shall be developed and training provided at a
minimum on an annual basis on proper spill response and cleanup procedures and
preventative maintenance activities for all personnel involved in any of the facility's
Page 5

Permit No. NCS000255
operations that have the potential to contaminate stormwater runoff. Facility personnel (or
team) responsible for implementing the training shall be identified in the Plan.
f. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be documented
and position(s) assignments provided.
g. Plan Ammendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants to surface waters. The Stormwater Pollution
Prevention Plan shall be reviewed and updated on an annual basis.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall
submit a time schedule to the Director for modifying the Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with Part
II, Standard Conditions, Section B, #9) to the Director that the changes have been made.
h. Facility Inspections. Inspections of the facility and all stormwater systems shall occur at a
minimum on a semiannual schedule, once in the fall (September -November) and once
during the spring (April - June). The inspection and any subsequent maintenance activities
performed shall be documented, recording date and time of inspection, individual(s)
making the inspection and a narrative description of the facility's stormwater control
systems, plant equipment and systems. Records of these inspections shall be incorporated
into the Stormwater Pollution Prevention Plan.
Visual monitoring as required in I.A.2.g.(3) shall be performed in addition to facility
inspections.
i. Implementation. implementation of the -plan shall include documentation of all monitoring,
measurements, inspections and maintenance activities and training provided to employees,
including the log of the sampling data and of activities taken to implement BMPs associated
with the industrial activities, including vehicle maintenance activities. Such documentation
shall be kept on -site for a period of five years and made available to the Director or his
authorized representative immediately upon request.
2.—Minimum Monitoring and Reporting Requirements
Minimum monitoring and reporting requirements are as follows unless otherwise approved in
writing by the Director of the Division of Environmental Management.
a. If a facility has multiple discharge locations with substantially identical stormwater
discharges that are required to be sampled, the permittee may petition the Director for
representative outfall status. If it is established that the stormwater discharges are
substantially identical and the permittee is granted representative outfall status, then
sampling requirements may be performed at a reduced number of outfalis.
b. Visual monitoring for color, odor, solids, foam, outfall staining, visible sheens and dry
weather flow shall be performed at all stormwater discharge outfall locations. All visual
monitoring shall be documented and records maintained with the Stormwater Pollution
Prevention Plan. The initial visual monitoring event shall be performed simultaneously
Page 6

Permit No. NCS000255
with the first analytical monitoring event and documentation of only this initial visual
monitoring event shall be submitted along with the required analytical monitoring submittal.
C. For purposes of the stormwater sampling required in this permit, all samples shall be
collected from a discharge resulting from a representative storm event (See Part II,
Standard Conditions, Section A). Failure to monitor storm events in accordance with the
specified frequency shall constitute a violation of this permit. If the stormwater runoff is
controlled by a detention pond, the following sampling requirements shall apply:
(1) If the detention pond detains the runoff generated by one inch of rainfall for 24
hours, visual observations for color, foam, outfali staining, visible sheens, and dry
weather flow are required, but analytical sampling shall not be required.
(2) If the detention pond discharges only in response to a storm event exceeding a 25-
year, 24-hour storm (See Part II, Standard Conditions, Section A), the pond shall
be considered a non -discharging ston-nwater control system and not subject to
NPDES requirements, unless the discharge causes a violation of water quality
standards.
d. Samples analyzed in accordance with the terms of this permit shall be submitted on forms
provided by the Director no later than January 31 for the previous year in which sampling
was required to be performed.
e. Analytical results from sampling during the final year of the permit term shall be submitted
with the permit renewal application.
f. This permit regulates stormwater discharges. Non-stormwater discharges which shall be
allowed in the stormwater conveyance system are:
(1) All other discharges that are authorized by a non-stormwater NPDES permit.
(2) Uncontaminated groundwater, foundation drains, air -conditioner condensate
without added chemicals, springs, discharges of uncontaminated potable water,
waterline and fire hydrant flushings, water from footing drains, flows from riparian
habitats and wetlands.
(3) Discharges resulting from fire -fighting.
If the storm event monitored and reported in accordance with this permit coincides with a
non-stormwater discharge, the permittee shall separately monitor and report all parameters
as required under the non-stormwater discharge permit and provide this information with
the stormwater discharge monitoring report
