Representative Outfall Status Request
ASMO North Carolina, Incorporated
Iredell County
The Mooresville Regional Office staff have reviewed your request dated July 1, 2014 for a determination that
stormwater discharge outfall (SDO) 002 be granted representative outfall status for stormwater outfalls 001
and 002. Based on the information provided and a site inspection by James Moore on July 29, 2014, we are
approving this request. In accordance with 40 CFR § 122.21(g) (7), you are authorized to sample outfall
number 002 as a representative outfall. This approval is effective with the next sampling event.
Please remember that any actions you initiate in response to benchmark exceedances as directed in the tiered
response provisions of your permit must address all drainage areas represented by SDO 002, where
appropriate.
Please append this letter to your Stormwater Pollution Prevention Plan (SPPP) or permit to document that
representative outfall status has been approved. If changes in drainage areas, structures, processes, storage
practices, or other activities occur that significantly alter the basis of this approval, representative outfall
status may no longer be valid. You should -either resume sampling at all SDOs, or reapply to this office for
representative outfall status based on updated information. If you have any questions or comments
concerning this letter, please contact James Moore at our Office at [phone].

To: Zahid S. Khan:
Please fired the enclosed Representative Outfall Status Request Form for
ASMO North Carolina, Inc. Facility.
Based on our and AMEC's review of the facility operations and StormWater sampling
results, ASMO North Carolina, Inc. requests reducing changing from sampling of
Outfalls One and Two to only sampling from Outfall 2.
ANC's basis of our request is the review of the sampling results from 2013 thru June of
2014, OF-2 represents the majority of industrial -related activities that occur in the
drainage area of OF-2.
Outfall 1 and 2, Each sampling event resulted in results that were usually within a couple
of hundredth's each time, thus OF 1 and OF2 have similar monitoring results.
If there any questions regarding this information please contact me at [phone] or

Da
if a facility is required to sample multiple discharge locations with very similar stormwater discharges, the
permittee may petition the Director for Representative Outfall Status {ROS). DWQ may grant RepresentaAtive
Outfali Status if stormwater discharges from a single outfall are representative of discharges from multiple
outfalls. Approved ROS will reduce the number of outfalls where analytical sampling requirements apply
if Representative Outfall Status is granted, ALL out are still subject to the qualitative nronrtang
requirements of the facility's permit —unless otherwise allowed by the permit (such as NCG62_00b j and DWQ
approval. The approval letter from DWQ must be kept an site with the facility's Stonnwater Pollution = GL
Prevention Plan. The facility must notify DWQ in writing if any changes affect representative status.

Monthly sampling was conducted in October 2013, January 2014, February 2014, March
2014, April 2014, and May 2014. Concentrations of zinc were detected at the facility
outfalls above the NCDENR benchmark value during the monthly sampling events.
Concentrations of copper were also detected above the benchmark concentration three
times in samples collected from outfall OF-1 and once in samples collected from OF-2
during the monthly sampling. Table 1 below summarizes the sampling results where there
were exceedances of the benchmark values.

Carolina Inc. facility located in Statesville, Iredell County. The facility was inspected on April
10, 2014 and was found to be in compliance with the tiered response actions and other
conditions of the NCG030000 General Permit.
As noted in the Engineering report conducted by AMEC Environment & Infrastructure,
Inc., "ASMO facility does not have regulated air discharges involving zinc or copper, nor does
the facility perform primary processing of zinc or copper components/materials or plating
operations involving zinc or copper. Minor finish cutting and painting of components is
performed inside the facility. ASMO collects and stores the recyclable scrap metal under roof,
and transports the materials off the site for processing. Based on analysis of one roof drain
sample, the roof of the facility is a potential source of zinc." Based on facility inspection and
the Engineering report by AMEC Environment & Infrastructure, Inc., the Division is granting
regulatory relief from the Tier responses. Upon receipt of this letter, the subject facility may
resume the permit specified semi-annual analytical monitoring for the remainder of the current
permit term. Your current permit is set to expire on 10/31/2017. This decision applies only to
the 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 or zinc at your facility that has the potential to be
exposed to stormwater. The relief granted in this letter is contingent upon the current

Inspection Summary:
Facility in Tier 3 and requesting reduction of monthly monitoring. Inspection revealed that most of the materials are under
roof except for the pallets. Also, it was noted that the parking lot have several small oil patches and plenty of brake dust.
Please note motor oil and hydrauloic fluid contain high concentration of zinc. If you see puddles or spots of oil or fluid,
clean them up directly. Debris on the ground such as dust, sawdust, dry leaves, or bark dust, may soak up oil and/or
hydraulic fluid. These can become a major source of zinc with rainfall and runoff.
Please sweep with industrial vacuum sweepers to clean paved areas prior to collectiong the samples. Please contact this
office to re -consider alternatives after two sampling events. Also, please inform us of the feasiblity of constructing a
bio-retention at discharge 01.

We are in receipt of the Stormwater Management Program Evaluation at ASMO North Carolina
Incorporated facility located in Statesville, Iredell County. The facility was inspected on April 10, 2014
and was found to be in compliance with the tiered response actions and other conditions of the
NCG030000 General Permit.
As noted in the Engineering report conducted by AMEC Environment & Infrastructure,
Incorporated, "ASMQ facility does not have regulated air discharges involving zinc or copper, nor does
the facility perform primary processing of zinc or copper components/materials or plating operations
involving zinc or copper. Minor finish cutting and painting of components is performed inside the
facility. ASMO collects and stores the recyclable scrap metal under roof, and transports the materials
off the site for processing. Based on analysis of one roof drain sample, the roof of the facility is a
potential source of zinc." Based on facility inspection and the Engineering report by AMEC
Environment & Infrastructure, Incorporated, the Division is granting regulatory relief from the Tier
responses. Upon receipt of this letter, the subject facility may resume the permit specified semi-annual
analytical monitoring for the remainder of the current permit term. Your current permit is set to expire
on 10/31/2017. This decision applies only to the 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 or 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

Dear Mr. Yount:
AMEC Environment & Infrastructure, Inc. (AMEC) is pleased to submit this letter report of
stormwater management program evaluation for the ASMO North Carolina, Inc. (ASMO)
facility located at 470 Crawford Road in Statesville, North Carolina. ASMO
manufactures/assembles electrical motors for automotive applications at the facility. This
letter report presents our understanding of background information, observations made by
AMEC during a site visit on April 15, 2014, a review of activities related to stormwater
management at the facility, and our conclusions and recommendations.
Background Information
The ASMO facility does not have regulated air, discharges involving zinc or copper, nor
does the facility perform primary processing of zinc or copper components/materials or
plating operations involving zinc or copper. Inside the facility, ASMO performs cold
stamping of rolled steel stock for producing components to be assembled. Minor finish
cutting and painting of components is performed inside the facility, and storage of raw
materials and finished products is inside the facility. ASMO collects and stores the
recyclable scrap metal under roof, and transports the material off the site for processing.
In accordance with a Certificate of Coverage under a general permit to discharge
stormwater under the National Pollutant Discharge Elimination System (NPDES General
Permit No. NCG030000), ASMO is required to collect semi-annual stormwater samples

from individual stormwater discharge outfall locations at the facility. Zinc was detected at
concentrations exceeding North Carolina Department of Environment and Natural
Resources (NCDENR) benchmark value at outfalls OF-1 (also known as 'Reliability') and
OF-2 (also known as 'WW Treat') during the 2013 semi-annual sampling events;
therefore, a Tier Two monitoring response, as described in the General Permit, is required
and has been implemented by ASMO. Figure 1 below contains a site plan with outfalls
OF-1 and OF-2 noted as '01' and '02', respectively. We understand ASMO contacted
NCDENR during the Tier Two response, as well as during the subsequent Tier Three
response.
Figure 1: Site Plan
The two stormwater outfalls at the facility drain to an unnamed tributary of Beaver Creek,
which is located near the southern property boundary and exits the property to the
southeast. This drainage feature is dry upstream from sample location OF-1. Downstream
of OF-1, groundwater seeps and discharges provide enough water to produce a base flow

in the drainage feature between sample location OF-1 and the discharge of OF-2. Beaver
Creek is a Class C waterway (from its source to its confluence with Fifth Creek) and does
not have impairments listed with the NCDENR Division of Water Quality (DWQ). The
unnamed tributary does not appear in the NCDENR DWQ Surface Water Classification
GIS (see Figures 2 and 3 below). Several minor stormwater outfalls, as well as several
non-stormwaterjfoundation drain outfalls, also drain to the unnamed tributary along the
facility's southern slope between OF-1 and OF-2.
Figures 2 and 3: Surface Water Classification Maps
A Tier Two response has been implemented at outfalls OF-1 and OF-2 at the facility due
to the detection of zinc above the NCDENR benchmark value for two consecutive
sampling events in 2013 (semi-annual sampling events). The Tier Two response requires
monthly monitoring for all parameters at each outfall where benchmark values for any

monitored constituent have been exceeded for two consecutive monitoring periods.
Monthly sampling was conducted in October 2013, January 2014, February 2014, March
2014, April 2014, and May 2014. Concentrations of zinc were detected at the facility
outfalls above the NCDENR benchmark value during the monthly sampling events.
Concentrations of copper were also detected above the benchmark concentration three
times in samples collected from outfall OF-1 and once in samples collected from OF-2
during the monthly sampling. Table 1 below summarizes the sampling results where there
were exceedances of the benchmark values.

The 'upstream' samples were collected northwest of OF-1 in the drainage ditch near the
outlet of drainage piping from the north (the grassed area and vehicle parking lot). The
'downstream' samples were collected in the unnamed tributary downstream of the
discharge of OF-2, but upstream of the confluence of a tributary draining from the
adjacent southern property. The downstream samples are combinations of the stormwater
discharging from OF-1, groundwater seeps/discharges, non-stormwater foundation drain
discharges, and stormwater discharging from OF-2.
As required by the tiered response system, ASMO performed inspections of the facility in
2013 and 2014 to identify potential sources of zinc and copper which .might be exposed to
stormwater. Table 3 below presents the identified potential sources and the corrective
actions ASMO has taken to address the potential sources.

NCDENR provided a Compliance Evaluation Inspection report, dated April 13, 2014,
based on an inspection visit on April 10, 2014. The report indicated that during NCDENR's
visit, the facility was in compliance with stormwater requirements. A summary of the
inspection is provided below.
Inspection Summary.
Facility in Tier 3 and requesting reduction of monthly monitoring. Inspection revealed that most of the materials are under
roof except for the pallets_ Also, it was noted that the parking lot have several small oil patches and plenty of brake dust.
Please note motor oil and hydrauloic fluid contain high concentration of zinc. If you see puddles or spots of oil or fluid,
clean them up directly. Debris on the ground such as dust, sawdust, dry leaves, or bark dust, may soak up oil andlor
hydraulic fluid. These can become a major source of zinc with rainfall and runoff.
Please sweep with industrial vacuum sweepers to clean paved areas prior to collectiong the samples. Please contact this
office to re -consider alternatives after two sampling events. Also, please inform us of the feasiblity of constructing a
bio-retention at discharge 01.

AMEC Site Visit Observations
During a walkover of the property on April 15, 2014, particularly the northern and southern
portions of the property where materials handling related to industrial activities occur,
AMEC personnel did not observe significant exposure of stormwater to materials involved
in industrial processes. New wooden pallets are located in the south-central portion of the
property. Containers for the collection of debris/waste and recyclable materials were
located under roof in an area north of the main operations building. A metal shipping
frame from receiving a piece of equipment was temporarily being stored in a grassed area
north of the main operations building, and was scheduled for removal. Materials which
would be an obvious significant source of zinc or copper exposure to stormwater were not
stored outside in these areas.
Review of Stormwater Activities
Ample stormwater samples have been collected at the facility over an appropriate period
of time to comply with the General Permit conditions. The concentrations of zinc detected
in the samples generally range from 0.100 milligrams per liter (mg/L) to 0.250 mg/L, with
an average concentration of 0.186 mgfL for OF-1 and an average concentration of 0.193
mg/L for OF-2.
A permissible non-stormwater discharge, consisting of foundation drains for capturing
underground springs in the area of machinery pits which were installed during
construction of the building, drains through OF-2. Analysis of this discharge reported a
zinc concentration of 0.029 mg/L. This concentration of zinc is included in the stormwater
discharges that occur through OF-2. 'Background' concentrations of zinc have also been
detected in the rain falling from the sky prior to contact with the facility (0.026 mg/L).
Inspections and corrective actions have been made over the past year to minimize
potential exposure of stormwater to materials and structures at the facility. Additional
procedural processes and modifications to operations have also been implemented.
These corrective actions were prompted by following the tiered response in the General
Permit, and thus, ASMO has complied with the General Permit conditions.

AMEC Project 6252-14-0134
May 27, 2014
Based on NCDENR's June 8, 2010, table Estimated NC Stormwater Metals Benchmarks
Based on Proposed Dissolved Water Quality Standards, the calculated revised/proposed
stormwater benchmarks for zinc and copper are 0.126 mg/L and 0.0105 mg/L,
respectively. Many of the outfall and sub -drainage basin zinc and copper concentrations
are below the proposed benchmarks, including the `downstream' sample, or near the
proposed benchmarks considering the `background' concentrations. AMEC notes that the
proposed aquatic life water quality standards, upon which the benchmarks are based
through a conversion of the dissolved zinc standard to a total zinc benchmark, are
developed assuming a total suspended solids (TSS) value of 10 mg/L, but the allowable
benchmark contained in the General Permit for Stormwater Discharge is 100 mg/L (as
applicable for this site with a receiving water classification of C).
ASMO personnel indicated future roofing repairs or new roofing proposed for the facility
would avoid materials containing zinc. A contractor quote was obtained for potential
replacement or coating of the facility's roof, but the cost of these measures are not
financially feasible compared to the benefit gained.
NCDENR observed small oil stains and brake dust in the vehicle parking area in the
northwestern portion of the site. Stormwater from this area drains to the south to the dry
drainage feature that leads to the OF-1 sampling location. The `upstream' stormwater
samples collected from the drainage from the parking areas in this drainage feature did
not contain copper above proposed benchmark value and zinc was not detected above
the laboratory reporting limit.
Implementation of a bioretention basin capable of addressing the 'first flush' of flow at OF-
1, or from the facility's roof, would be difficult and expensive considering the large size of
the drainage area. A retrofit of the inlet to the pipe leading to OF-1 to create a
retention/detention pond or potential wetland is possible; however, there is currently
limited data available concerning the removal of dissolved or total zinc in such situations.
Evaluation of other factors involving the potential impact of stormwater discharge into the
unnamed tributary near outfall OF-2 would be appropriate prior to constructing
management features such as basins or ponds in an attempt to reduce total zinc
concentrations, which might not affect dissolved zinc concentrations upon which the water
quality benchmarks are based.

AMEC Project 6252-1"134
Conclusions and Recommendations
Ample stormwater samples have been collected from the designated outfall discharge
locations, as well as from additional sub -drainage basins at the facility, to comply with the
General Permit conditions. Based on the sampling results, evaluation and observation of
the facility's operations, and comparison of the zinc and copper analytical results to
current and proposed benchmarks, industrial processes at the facility do not appear to
impact stormwater by zinc and copper exposure. Based on analysis of one roof drain
sample, the roof of the facility is a potential source of zinc; however, there is not enough
data to determine if the roof is an ongoing potential source of significant zinc.
ASMO should continue to monitor rainfall conditions and, as requested by NCDENR,
sample outfalls OF-1 and OF-2 during a measureable storm event in June 2014 (or next
appropriate measureable discharge event). 4fires6lt§90f_th . Jue e,2014 =or-next=rnonti lys
sampling:event;.are2sitiilarsto,cesults'-from previous�sarripiing:ev®rests, AMEC recommends
returning to semi-annual outfall discharge sampling, with particular attention to
implementing good housekeeping in the northern and southern areas of the facility. If
future roof repair/replacement projects are proposed, consideration should be given to the
use of materials that do not contain zinc.
AMEC recommends submitting this evaluation of the stormwater management system to
NCDENR for their files. AMEC recommends contacting the NCDENR Mooresville
Regional Office industrial stormwater designee for Iredell County to discuss the results of
the recent monthly response sampling, the results of the 'investigative' sampling, this
evaluation of the stormwater program, and a tentative future sampling schedule.
Based on the review of historic sampling results, AMEC also recommends that ASMO
complete a representative outfall status form available from NCDENR and request that
outfall OF-2 be representative of outfall OF-1. The majority of industrial -related activities
occur in the drainage area of OF-2.

3.3 List of Significant Spills
There have not been any significant spills (i.e., spills that have exceeded their reportable quantities) at the site
within the last 3 years. Form EF - 005 should be used to document any future significant spills that do occur.
Employees will notify supervisors in the event of a spill so the spill response team members can respond.
This form should be used to document any spill occurring on the property that triggers reporting requirements
under Local, State, and Federal Regulations:
33.1 Oil Release Reporting
Federal and state regulations (NCGS143-215.75) require reporting of oil spills> 25 gallons to the
ground, causing sheen on or within 100 yards of surface water, or those that take longer than 24
hours to clean up.
3.3.2 Hazardous Substance Release
Federal and state regulations (NCGS 143-215.75) require reporting of specific to hazardous substance
spills to the surface water in excess of reportable quantities (40CFR117 & 40CFR302). The
thresholds for spill reporting are dependant on the hazardous substance and are in increments of 1,
10, 100, 1,000, & 5,000 pounds
3.4 Non -Storm water Discharges & Annual Certification Statement
ASMO North Carolina, Inc. has completed an evaluation of the site and outfalls to assure that there are no
non -storm water discharges other than those permitted by the State of North Carolina. The facility has also
completed analytical assessments of the outfalls to assure that storm water quality is not affected by industrial
activities. Below is the signed certification statement that the storm water outfalls have been evaluated for
non -storm water discharges as required in Part III, Standard Conditions, Section B, Paragraph 5.
Certification Statement
I certify that the storm water outfalls have been evaluated for the presence of non-stonn water discharges.
Based upon my inquiry of the person or person 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 storm water or onto areas which are exposed
to rainfall or storm water runoff has occurred since filing the last discharge monitoring report_ I further certify
that this facility is implementing all the provisions of the Solvent Management Plan included in the Storm
water Pollution Prevention Plan.
I certify that the Annual Training Requirements have been met for the CY 2013.
1 certify that the Best Management Practices followed or conducted during the year are most effective.
I certify no significant spills or leaks have occurred during the CY2013.
I certify a review of the benchmark values of the analytical data has occurred after the Fall 2013 sample
during CY2013. As a result of the sample results on Zinc, ASMO NC is now in a Tiered Two Level and has
implemented countermeasures to reduce the amount of Zinc in their storm water.

4 Storm water Management Strategy
ASMO North Carolina, Inc. has assessed its storm water management and implemented the following programs to
minimize storm water pollution. The best management practices include activities to prevent industrial activities
impacting storm water quality as well as practices to improve quality of storm water leaving the property
4.1 Best Management of Storm water
The site channels storm water directly from downspouts and parking areas through conduit to outfall
locations. Outfall 1 has cement channels handling some flow to minimize erosion and riprap at its outfall
point. Outfall 2 has riprap at its outfall point.
4.2 Best Management of Pollution Sources
ASMO North Carolina, Inc. has an Environmental Management System that drives proper management of
chemicals and waste and requires goals for reducing environmental 'impacts. This program also requires a
corrective and preventive action system to document and resolve environmental issues including those related
to storm water pollution. The Preventive Maintenance and Good Housekeeping Program provides a listing of
those items that assist in reducing storm water contamination. Additionally the site follows the practices
below to prevent pollution of storm water.
4.2.1a) BMP Summary 11
The rationale behind the installation and selection of ANC's BMP's is a logical, methodical listing of best
practices found during the course of the year by inspecting ASMO's site, by bench marking other ASMO
sites and by bench marldng similar manufacturing companies:

4.2.1 b) Secondary Containment
The only externally stored bulk chemical on the site is lubricating oil stored in a 5,000 gallon tank
The tank and its management is covered under the site SPCC plan reference in section 6.
4.2.2 Feasibility Study
The site has effectively enclosed all chemical storage areas and potential sources for storm water
pollution. An annual review of the technical and economic feasibility of changing methods of
operations and / or storage practices to eliminate or reduce exposure of materials and processes to
rainfall and run-on flows. Wherever practical, ASMO shall prevent exposure of all storage areas,
material handling operations, and manufacturing operations. In areas where elimination is not
possible, like the galvalume roof runoff which contains zinc, this review shall document the
feasibility of diverting the storm water run-on away from practical areas of potential contamination.
EMSI-0123-105
Page: 6

4.2.3 Loading and Unloading
All raw materials, intermediate materials, finished products, byproducts, and shipping materials are
to be loaded and unloaded at the inside shipping and receiving bays except for waste containers or
Mobil products or Press Oil from Fuchs or Fuel Oil for Diesel Pump.
4.2 3.1 All paint related materials (200 B KAI, 100 C, ACC No. 2 Blend Thinner, ACC Cleaning
Solvent) are unloaded in the facility and are immediately moved to the Flammable Building.
These materials are flammable and shall be stored inside of the flammable building. The drums
shall he inspected for leaks before, during and after they are unloaded from the truck. All
material shall be unloaded from the truck and immediately transported to the flammable
building. The material shall not be left unattended in the main facility. The receiving associate
will conduct the inspection for leaks. If any leaks are detected, then they will call security to
notify an ERT associate to come and respond to a spill cleanup. The receiving associate can
minimize any spills from containers by placing the leaking side or bottom or top of a drum
turned up to prevent additional spillage, without risking their safety or health.
4.23.2 All Class I and Class lI Flammable materials which are received in quantities greater than or
equal to 5 gallons shall be unloaded and immediately moved to the flammable building.
4.2.33 The hazardous and non -hazardous waste drums are loaded at the outside loading dock The
material shall be removed from the locked hazardous storage room and the shelter behind the
recycle building, and placed under the shelter behind the recycle building. The drums shall be
inspected for leaks by a facility associate before, during and after loading onto the truck. Any
leaks will be promptly reported to an ERT associate during white the containers are being loaded
onto the truck Usually, one or two EHS Associates are assisting with the loading of the truck,
and they are trained to respond to spills.
4.2.3.4 All lubricants (oil) and solvents (kerosene) that will be stored in the oil storage building should
be unloaded and moved to the oil storage room in the recycle building. The drums shall be
inspected for leaks before, during and after they are unloaded from the truck. All material shall
be unloaded from the truck and immediately transported to the oil storage building. The material
shall not be left unattended except while transporting it to the oil storage location. The receiving
associate will conduct the inspection for leaks. If any leaks are detected, then they will call
security to notify an ERT associate to come and respond to a spill cleanup. The receiving
associate can minimize any spills from containers by placing the leaking side or bottom or top of
a drum turned up to prevent additional spillage.
4.2.3.5 The empty chemical drums that are generated from any process shall be stored outside under the
shelter and loaded onto the trucks at the outside loading dock_
4.2.3.6 The non -hazardous bulk material is stored in totes in the recycle materials building until the non-
hazardous waste contractor arrives with a truck. The containers are placed on the cement pad in
front or the side of the recycle building. The containers shall be inspected for leaks before,
during and after loading onto the truck. The material shall not be left unattended, while it is
outside of the building except while the material is being loaded onto the truck. (Note: Totes are
either shipped off site or pumped out by a Vacuum Truck If pumped out by a vacuum truck, the
totes are staged under the shelter, till all totes are emptied. ) A EHS associate will conduct the
inspection for leaks. If any leaks are detected, then they will call security to notify an ERT
associate to come and respond to the spill. Usually, one or two EHS Associates are assisting
with the loading of the truck, and they are trained to respond to spills. The EHS associate can
minimize any spills from containers by placing the leaking side or bottom or top of drum
turned up to prevent additional spillage.
F-MSI-0123-105
Page: 7

4.2.3.7 The full used oil totes shall be stored in the Press or Shaft department and until ready to place in
the shelter or in the recycle building non -hazardous used oil storage locations. The totes shall be
inspected for leaks by each department associates, by either a press or shaft associate, before
they are moved to the recycle building or shelter. If any leaks are detected, then they will call'
security to notify an ERT associate to come and respond to the spill. The full used oil totes shall
not be moved if any leaks are detected. The empty totes shall be stored inside the building until
each department such as press or shaft needs to pick up the empty totes.
4.2.3.8 The water used for the cooling tower on the south end of the facility will be checked on a daily
basis, except during holiday weekends when the cooling lower is shut down. The water meter
reading will be recorded on the Process Water Log Form. A facility associate will then subtract
the reading from the reading recorded on the previous reading. The facility associate will plot
the usage on the chart portion of the Process Water Forms. If an abnormal reading is indicated,
by going significantly above the upper (red) process limit, the facility and environmental, health,
& safety specialist will be notified. (Note: Going significantly over the process limit is defined
as going plus +5 above the current process limit.) If the abnormal reading is due to a bad or
defective conductivity probe, then the probe will be replaced. If the abnormal reading is due to
an unknown cause, then it should be investigated, until a cause is found. The purpose for the
daily checks of water usage for the cooling towers is for two reasons: 1) In case a pipe has
ruptured underground, sending water with biocides to the local outside stream, thus in violation
of storm water & non contact cooling water regulations, 2) In case extra water is being
discharged to waste water pre-treatment, due to a possible defective conductivity probe or
controls, thus causing a possible violation of Emergency Water Restrictions, if so being enforced
at the time of the incident. (EF-072)
4.23.9 The grinding swarf hopper shall not be over filled in the shaft department, to minimize spillage
during movement to the Recycle Building. At no point shall the shaft associate leave the hopper
outside before dumping for any extended time. If any spillage occurs, the liquid will be
absorbed by the spill absorbent material available in the Recycle building. After absorbing any
spilled grinding swarf liquid, then used absorbent will be placed in an Absorbent & Oil Waste
Drum.
4.2.3.10 Unloading of Press Oil or Diesel Fuel, the Press or Facility associates will follow the
instructions as outlined in the S.P.C.C. (Spill Prevention Control & Countermeasure) Plan
(EMSI-0 123-187). (Note: Section 7.0 TANK TRUCK OIL UNLOADING PROCEDURE)_
4.2.4 Handling Instructions
4.2.4.1 All drums (empty or full) shall be handled with caution. The drums shall be placed on pallets, 4
drums per pallet. The pallet shall contain no more than four drums at a time. A forklift with the
proper attachments may carry a single drum at a time. (Note: If single drum handling occurs with
a fork lift, the driver of the lift MUST carry the drum as low to the ground as possible.) Pallet
jacks may be used in place of a forklift in carrying a pallet of drums, or two drums without a
pallet. At no time should a forklift or pallet jack be used to move more than one pallet of drums
at a time.
4.2.5 Storage Instructions
4.2.5.1 All raw materials, intermediate materials, finished products, shipping materials and byproducts
are stored inside of a building, except for the new pallets. The new pallets are stored outside in
contact with storm water due to the Iow potential of contamination resulting from contact with
this natural material.
4.2.5.2 All paint, thinner, solvents, grease drums, and related products shall be stored in the flammable
building on heavy-duty pallets with no more than 4 drums to a pallet. The pallets will be single
stacked (no pallets stacked on top of one another), except for grease drums, in the flammable
building.
EMSI-0123-105
Page: 8

4.2.5.3 All Class I and Class II Flammable materials in containers greater than or equal to 5 gallons
shall be stored in the flammable storage building, or an approved flammable storage cabinet.
4.2.5.4 All dumpsters or waste containers shall remain covered or closed at all times except while
placing material into the container.
4.2.5.5 All lubricants (oil) and solvents (kerosene) shall be stored in the oil storage building with no
more than 4 drums to a pallet.
4.2.5.6 The empty drums that are generated from the process shall be stored outside under the shelter,
stacked two to three pallets high segregated by the type of drum. (Note: Mobil drums are kept in
their separate row near the rear of the shelter.)
4.2.5.7 The empty press or shaft totes shall be stored inside the facility until the supplier arrives to pick
up the empty totes.
4.2.6 Vehicle Maintenance
4.2.6.1 All forklift and other vehicle maintenance shall be performed under the shelter behind the
recycle materials building, inside the building, or at an offsite location. If any maintenance
activity must be performed outside and not under the afore mentioned shelter then a written
request to perform the maintenance activities must be submitted to the Environmental Health and
Safety department listing the activities being performed, the location, who will be performing the
activities, a list of the potential contaminants with a copy of the material safety data sheets for
the contaminants, or a laboratory analysis for the material, for approval before any activities can
begin. All vehicle washing shall be performed at an off -site location. This practice cannot take
place due to the possibility of storm water contamination.

5.2 Employee Training
All employees are provided awareness training related to hazardous materials. Spill Response Team members,
Receiving or Shipping Associates who handle containers of liquid chemicals, Process Associates such as
Press, Paint, Shaft, and Molding Associates, and those associates who have the potential to affect rain or
storm water by handling or moving containers of liquid chemicals or liquid waste fluids such as Used Oil or
Waste Paint & Thinner and other chemicals that have the potential to contaminate rain or storm water will be
trained annually on spill response and cleanup and preventive maintenance activities. The annual training shall
be documented by the signature of each employee trained.
5.3 Facility Inspections
ASMO North Carolina, Inc. is required by the storm water permit to inspect the plant, outdoor areas, storage
areas, and storm water outfalls at least twice per year, once in the fall (July. -Dec.) and once in the spring (Jan -
June), with at least 60 days separating the inspection dates. The inspection does not need to occur during a
representative storm event. Inspections of the facility and storm water systems shall occur as part of the
Preventive Maintenance and Good Housekeeping Program. The facility inspections are different from and in
addition to the storm water discharge characteristic monitoring (Qualitative Monitoring) at the out falls.
The qualitative inspection will occur during a measurable storm water event (On a semi-annual schedule) and
will be documented using the form provided in the general permit (EF-239). Any corrective actions or
EMSt-0123-105
Page. 9

preventive maintenance will be documented using the corrective preventive action reporting system.
ASMO North Carolina, Inc. is also required to complete analytical sampling as detailed in Section B of the
storm water permit annually. The initial sampling event must coincide with the first qualitative inspection of
the outfalls and must be completed during a representative storm event.
5.3.1 The sampler shall complete the following actions:
53.11 Document the rain event using Form 239 including the rain pH.
5.3.1.2 Attached the chain of custody to Form 239 and submit to the EHS Department.
5.3.13 Attach the completed qualitative Form 238 from the storm water permit.
5.3.2 The EHS Department shall complete the following actions:
5.3.2.1 Attach precipitation records from the Statesville airport
bttg:l/www.v=dereround.com/lustory�/airport(KSVH{ to Semi -Annual Stormwater Discharge
Monitoring Report or EF-239
5.3.2.2 Attach analytical test results to Form 239..
5.3.2.3 Submit the documentation for recordkeeping
5.3.2.4 Report sampling data to DENR per permit requirements.
5.4 Use of Spill Magnet Drain Blockers & Unloading Monitoring of Press Stamping Oil or Diesel Fuel.
Purpose: Associates MUST follow and adhere to Spill Prevention, Control, and Countermeasures during
unloading of oil, which will prevent large amounts of oil to get into storm drains.
5.5 Non- Storage of Used Equipment — Equipment that still contain Oil or Grease outside.
All Used Equipment must be stored either behind Recycle Building, in the Flammable Building, or Shipped
Off Site for Storage or To Scrap the equipment. Purpose: To Prevent Oil or Grease stored in equipment from
getting into storm drain. To prevent rusting of steel, thus allowing zinc, copper, or Lead from getting into
storm or rain water.
5.6 Reduction of Scrap Metal being exposed to Storm Water
Any metal fixture, cabinet, bollard, etc. that can rust will be kept painted. If the item is found not be used or
needed, then it will be removed and sent to the scrap metal recycling company.
5.7 Reduction of Sediment getting into Storm Water 11
Any drainage ditch, either lined with rip rap or concrete, must be maintained to reduce sediment that could get
into the storm water. If drainage ditch condition deteriorates, then repairs must be implemented to reduce the
chance of sediment getting into the storm water, as soon as it is economically feasible.
5.8 Reduction of Rusting Metal Doors, Air Handlers, Fire Equipment Cabinets, Bollards, Tanks 11
Any rusted door, air handler, fire equipment cabinets, bollards, or items like the bridges for piping going to
wastewater treatment will be pressure washed, and then painted with primer and then the color paint needed
for each item. The painting of the metal items such as described above will occur on a as needed basis. If
painting is deemed not effective and the item is deemed in need of replacement, then this will be scheduled as
soon as it is economically feasible.

3.3 List of Significant Spills
There have not been any significant spills (i.e., spills that have exceeded their reportable quantities) at the site
within the last 3 years. Form EF - 005 should be used to document any fixture significant spills that do occur.
Employees will notify supervisors in the event of a spill so the spill response team members can respond.
This form should be used to document any spill occurring on the property that triggers reporting requirements
under Local, State, and Federal Regulations:
3.3.1 Oil Release Reporting
Federal and state regulations (NCGS 143-215.75) require reporting of oil spills > 25 gallons to the
ground, causing sheen on or within 100 yards of surface water, or those that take longer than 24
hours to clean up.
3.3.2 Hazardous Substance Release
Federal and state regulations (NCGS 143-215.75) require reporting of specific to hazardous substance
spills to the surface water in excess of reportable quantities 40CFR 117 & 40CFR302). The
thresholds for spill reporting are dependant on the hazardous substance and are in increments of 1,
10, 100, 1,000, & 5,000 pounds
3.4 Non -Storm water Discharges & Annual Certification Statement 00
ASMO North Carolina, Inc. has completed an evaluation of the site and outfalls to assure that there are no
non -storm water discharges other than those permitted by the State of North Carolina. The facility has also
completed analytical assessments of the ourfalls to assure that storm water quality is not affected by industrial
activities. Below is the signed certification statement that the storm water outfalls have been evaluated for
non -storm water discharges as required in Part 11I, Standard Conditions, Section B, Paragraph 5.
Certification Statement
I certify that the storm water outfalls have been evaluated for the presence of non -storm water discharges.
Based upon my inquiry of the person or person 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 storm water or onto areas which are exposed
to rainfall or storm water runoff has occurred since filing the last discharge monitoring report. i further certify
that this facility is implementing all the provisions of the Solvent Management Plan included in the Storm
water Pollution Prevention Plan.
I certify that the Annual Training Requirements have been met for the CY 2011
I certify that the Best Management Practices followed or conducted during the year are most effective.
1 certify no significant spills or leaks have occurred during the CY2013.
I certify a review of the benchmark values of the analytical data has occurred after the Fall 2013 sample
during CY2013. As a result of the sample results on Zinc, ASMO NC is now in a Tiered Two Level and has
implemented countermeasures to reduce the amount of Zinc in their storm water.

4 Storm water Management Strategy
ASMO North Carolina, Inc. has assessed its storm water management and implemented the following programs to
minimize storm water pollution. The best management practices include activities to prevent industrial activities
impacting storm water quality as well as practices.to improve quality of storm water leaving the property
4.1 Best Management of Storm water
The site channels storm water directly from downspouts and parking areas through conduit to outfall
locations. Outfall 1 has cement channels handling some flow to minimize erosion and riprap at its outfall
point. Outfall 2 has riprap at its outfall point.
4.2 Best Management of Pollution Sources
ASMO North Carolina, Inc. has an Environmental Management System that drives proper management of
chemicals and waste and requires goals for reducing environmental impacts. This program also requires a
corrective and preventive action system to document and resolve environmental issues including those related
to storm water pollution. The Preventive Maintenance and Good Housekeeping Program provides a listing of
those items that assist in reducing storm water contamination. Additionally the site follows the practices
below to prevent pollution of storm water.
4.2.1 a) BMP Summary 11
The rationale behind the installation and selection of ANC's BMP's is a logical, methodical listing of best
practices found during the course of the year by inspecting ASMO's site, by bench marking other ASMO
sites, and by bench marking similar manufacturing companies:

4.2.1 b) Secondary Containment
The only externally stored bulk chemical on the site is lubricating oil stored in a 5,000 gallon tank.
The tank and its management is covered under the site SPCC plan reference in section 6.
4.2.2 Feasibility Study
The site has effectively enclosed all chemical storage areas and potential sources for storm water
pollution. An annual review of the technical and economic feasibility of changing methods of
operations and 1 or storage practices to eliminate or reduce exposure of materials and processes to
rainfall and run-on flows. Wherever practical, ASMO shall prevent exposure of all storage areas,
material handling operations, and manufacturing operations. In areas where elimination is not
possible, like the galvaiume roof runoff which contains zinc, this review shall document the
feasibility of diverting the storm water run-on away from practical areas of potential contamination.

4.2.3 Loading and Unloading
All raw materials, intermediate materials, finished products, byproducts, and shipping materials are
to be loaded and unloaded at the inside shipping and receiving bays except for waste containers or
Mobil products or Press Oil from Fuchs or Fuel Oil for Diesel Pump.
4.2.3.1 All paint related materials (200 B KAI, 100 C, ACC No. 2 Blend Thinner, ACC Cleaning
Solvent) are unloaded in the facility and are immediately moved to the Flammable Building.
These materials are flammable and shall be stored inside of the flammable building. The drums
shall be inspected for leaks before, during and after they are unloaded from the truck. All
material shall be unloaded from the truck and immediately transported to the flammable
building. The material shall not be left unattended in the main facility. The receiving associate
will conduct the inspection for leaks. If any leaks are detected, then they will call security to
notify an ERT associate to come and respond to a spill cleanup. The receiving associate can
minimize any spills from containers by placing the leaking side or bottom or top of a drum
turned up to prevent additional spillage, without risking their safety or health_
4.2.3.2 All Class I and Class It Flammable materials which are received in quantities greater than or
equal to 5 gallons shall be unloaded and immediately moved to the flammable building.
4.2.3.3 The hazardous and non -hazardous waste drums are loaded at the outside loading dock. The
material shall be removed from the locked hazardous storage room and the shelter behind the
recycle building, and placed under the shelter behind the recycle building. The drums shall be
inspected for leaks by a facility associate before, during and after loading onto the truck. Any
leaks will be promptly reported to an ERT associate during while the containers are being loaded
onto the truck. Usually, one or two EHS Associates are assisting with the loading of the truck,
and they are trained to respond to spills.
4.2.3.4 All lubricants (oil) and solvents (kerosene) that will be stored in the oil storage building should
be unloaded and moved to the oil storage room in the recycle building. The drums shall be
inspected for leaks before, during and after they are unloaded from the truck. All material shall
be unloaded from the truck and immediately transported to the oil storage building. The material
shall not be left unattended except while transporting it to the oil storage location. The receiving
associate will conduct the inspection for leaks. If any leaks are detected, then they will call
security to notify an ERT associate to come and respond to a spill cleanup. The receiving
associate can minimize any spills from containers by placing the leaking side or bottom or top of
a drum turned up to prevent additional spillage.
4.2.3.5 The empty chemical drums that are generated from any process shall be stored outside under the
shelter and loaded onto the tracks at the outside loading dock.
4.2.3.6 The non -hazardous bulk material is stored in totes in the recycle materials building until the non-
hazardous waste contractor arrives with a truck. The containers are placed on the cement pad in
front or the side of the recycle building. The containers shall be inspected for leaks before,
during and after loading onto the truck. The material shall not be left unattended, while it is
outside of the building except while the material is being loaded onto the truck. (Note: Totes are
either shipped off site or pumped out by a Vacuum Truck. If pumped out by a vacuum truck, the
totes are staged under the shelter, till all totes are emptied. ) A EHS associate will conduct the
inspection for leaks. If any leaks are detected, then they will call security to notify an ERT
associate to come and respond to the spill. Usually, one or two EHS Associates are assisting
with the loading of the truck, and they are trained to respond to spills. The EHS associate can
minimize any spills from containers by placing the leaking side or bottom or top of a drum
turned up to prevent additional spillage.
FASI-0123-105

4.2.3.7 The full used oil totes shall be stored in the Press or Shaft department and until ready to place in
the shelter or in the recycle building non -hazardous used oil storage locations. The totes shall be
inspected for leaks by each department associates, by either a press or shaft associate, before
they are moved to the recycle building or shelter. If any leaks are detected, then they will call
security to notify an ERT associate to come and respond to the spill. The full used oil totes shall
not be moved if any leaks are detected. The empty totes shall be stored inside the building until
each department such as press or shaft needs to pick up the empty totes.
4.2.3.8 The water used for the cooling tower on the south end of the facility will be checked on a daily
basis, except during holiday weekends when the cooling tower is shut down. The water meter
reading will be recorded on the Process Water Log Form. A facility associate will then subtract
the reading from the reading recorded on the previous reading. The facility associate will plot
the usage on the chart portion of the Process Water Forms. If an abnormal reading is indicated,
by going significantly above the upper (red) process limit, the facility and environmental, health,
& safety specialist will be notified. (Note: Going significantly over the process limit is defined
as going plus +5 above the current process limit.) If the abnormal reading is due to a bad or
defective conductivity probe, then the probe will be replaced. If the abnormal reading is due to
an unknown cause, then it should be investigated, until a cause is found. The purpose for the
daily checks of water usage for the cooling towers is for two reasons: 1) In case a pipe has
ruptured underground, sending water with biocides to the local outside stream, thus in violation
of storm water & non contact cooling water regulations, 2) In case extra water is being
discharged to waste water pre-treatment, due to a possible defective conductivity probe or
controls, thus causing a possible violation of Emergency Water Restrictions, if so being enforced
at the time of the incident. (EF-072)
4.2.3.9 The grinding swarf hopper shall not be over filled in the shaft department, to minimize spillage
during movement to the Recycle Building. At no point shall the shaft associate leave the hopper
outside before dumping for any extended time_ If any spillage occurs, the liquid will be
absorbed by the spill absorbent material available in the Recycle building. After absorbing any
spilled grinding swarf liquid, then used absorbent will be placed in an Absorbent & Oil Waste
Drum.
4.2.3.10 Unloading of Press Oil or Diesel Fuel, the Press or Facility associates will follow the
instructions as outlined in the S.P.C.C_ (Spill Prevention Control & Countermeasure) Plan
(EMSI-0123-187) . (Note: Section 7.0 TANK TRUCK OIL UNLOADING PROCEDURE).
4.2.4 Handling Instructions
4.2.4.1 All drums (empty or full) shall be handled with caution. The drums shall be placed on pallets, 4
drums per pallet. The pallet shall contain no more than four drums at a time. A forklift with the
proper attachments may carry a single drum at a time. (Note: If single drum handling occurs with
a fork lift, the driver of the lift MUST carry the drum as low to the ground as possible.) Pallet
jacks may be used in place of a forklift in carrying a pallet of drums, or two drums without a
pallet. At no time should a forklift or pallet jack be used to move more than one pallet of drums
at a time.
4.2.5 Storage Instructions
4.2.5.1 All raw materials, intermediate materials, finished products, shipping materials and byproducts
are stored inside of a building, except for the new pallets. The new pallets are stored outside in
contact with storm water due to the low potential of contamination resulting from contact with
this natural material.
4.2.5.2 All paint, thinner, solvents, grease drums, and related products shall be stored in the flammable
building on heavy-duty pallets with no more than 4 drums to a pallet. The pallets will be single
stacked (no pallets stacked on top of one another), except for grease drums, in the flammable
building.
EMSI-0123-105
Page: 8

4.25.3 All Class I and Class II Flammable materials in containers greater than or equal to 5 gallons
shall be stored in the flammable storage building, or an approved flammable storage cabinet.
4.2.5.4 All dumpsters or waste containers shall remain covered or closed at all times except while
placing material into the container.
4.2.5.5 All lubricants (oil) and solvents (kerosene) shall be stored in the oil storage building with no
more than 4 dnuns to a pallet.
4.2.5.6 The empty drums that are generated from the process shall be stored outside under the shelter,
stacked two to three pallets high segregated by the type of drum. (Note: Mobil drums are kept in
their separate row near the rear of the shelter.)
4.2.5.7 The empty press or shaft totes shall be stored inside the facility until the supplier arrives to pick
up the empty totes.
4.2.6 Vehicle Maintenance
4.2.6.1 All forklift and other vehicle maintenance shall be performed under the shelter behind the
recycle materials building, inside the building, or at an offshe location. If any maintenance
activity must be performed outside and"not under the afore mentioned shelter then a written
request to perform the maintenance activities must be submitted to the Environmental Health and
Safety department listing the activities being performed, the location, who will be performing the
activities, a list of the potential contaminants with a copy of the material safety data sheets for
the contaminants, or a laboratory analysis for the material, for approval before any activities can
begin. All vehicle washing shall be performed at an off -site location. This practice cannot take
place due to the possibility of storm water contamination.
S Spill Prevention and Response Plan
5.1 Emergency Contact and Spill Response
ASMO North Carolina, Inc. has implemented a Hazardous Waste Contingency Plan and Spill Response Plan
for any emergency including the event of a spill. These plans are maintained separate from this plan. The
emergency contacts for any emergency event are listed in Hazardous Waste Contingency Plan reference in
Section 6, The Spill Response (ERTO team members are defined in EF-9991tem 9 12,
5.2 Employee Training
All employees are provided awareness training related to hazardous materials. Spill Response Team members,
Receiving or Shipping Associates who handle containers of liquid chemicals, Process Associates such as
Press, Paint, Shaft, and Molding Associates, and those associates who have the potential to affect rain or
storm water by handling or moving containers of liquid chemicals or liquid waste fluids such as Used Oil or
Waste Paint & Thinner and other chemicals that have the potential to contaminate rain or storm water will be
trained annually on spill response and cleanup and preventive maintenance activities. The annual training shall
be documented by the signature of each employee trained.
5.3 Facility Inspections
ASMO North Carolina, Inc. is required by the storm water permit to inspect the plant, outdoor areas, storage
areas, and storm water outfalls at least twice per year, once in the fall (July. -Dec.) and once in the spring (Jan -
June), with at least 64 days separating the inspection dates. The inspection does not need to occur during a
representative storm event. Inspections of the facility and storm water systems shall occur as part of the
Preventive Maintenance and Good Housekeeping Program. The facility inspections are different from and in
addition to the storm water discharge characteristic monitoring (Qualitative Monitoring) at the out falls.
The qualitative inspection will occur during a measurable storm water event (On a semi-annual schedule) and
will be documented using the form provided in the general permit (EF-239). Any corrective actions or
EMSI-0123-105
Page: 9

preventive maintenance will be documented using the corrective preventive action reporting system.
ASMO North Carolina, Inc. is also required to complete analytical sampling as detailed in Section B of the
storm water permit annually. The initial sampling event must coincide with the first qualitative inspection of
the outfalls and must be completed during a representative storm event.
5.3.1 The sampler shall complete the following actions:
5.3.1.1 Document the rain event using Form 239 including the rain pH.
5.3.1.2 Attached the chain of custody to Form 239 and submit to the EHS Department.
5.3.1.3 Attach the completed qualitative Form 238 from the storm water permit.
5.3.2 The EHS Department shall complete the following actions:
5.3.2.1 Attach precipitation records from the Statesville airport
hyp://www.w-undemround.com/Mstor-v/ai!port[KSV to Semi -Annual Stormwater Discharge
Monitoring Report or EF-239
5.3.2.2 Attach analytical test results to Form 239..
5.3.2.3 Submit the documentation for recordkeeping
5.3.2.4 Report sampling data to DENR per permit requirements.
5.4 Use of Spill Magnet Drain Blockers & Unloading Monitoring of Press Stamping Oil or Diesel Fuel.
Purpose: Associates MUST follow and adhere to Spill Prevention, Control, and Countermeasures during
unloading of oil, which will prevent large amounts of oil to get into storm drains.
5.5 Non- Storage of Used Equipment — Equipment that still contain Oil or Grease outside.
All Used Equipment must be stored either behind Recycle Building, in the Flammable Building, or Shipped
Off Site for Storage or To Scrap the equipment. Purpose: To Prevent Oii or Grease stored in equipment from
getting into storm drain. To prevent rusting of steel, thus allowing zinc, copper, or Lead from getting into
storm or rain water.
5.6 Reduction of Scrap Metal being exposed to Storm Water
Any metal fixture, cabinet, bollard, etc, that can rust will be kept painted. If the item is found not be used or
needed, then it will be removed and sent to the scrap metal recycling company.
5.7 Reduction of Sediment getting into Storm Water 11
Any drainage ditch, either lined with rip rap or concrete, must be maintained to reduce sediment that could get
into the storm water. if drainage ditch condition deteriorates, then repairs must be implemented to reduce the
chance of sediment getting into the storm water, as soon as it is economically feasible.
5.8 Reduction of Rusting Metal Doors, Air Handlers, Fire Equipment Cabinets, Bollards, Tanks 11
Any rusted door, air handler, fire equipment cabinets, bollards, or items like the bridges for piping going to
wastewater treatment will be pressure washed, and them painted with primer and then the color paint needed
for each item. The painting of the metal items such as described above will occur on a as needed basis. if
painting is deemed not effective and the item is deemed in need of replacement, then this will be scheduled as
soon as it is economically feasible.

Subject. NPDES Stormwater Permit Coverage Renewal
ASMO North Carolina, Inc.
COC Number NCG030537
Iredell County
In response to your renewal application for continued coverage under stormwater General Permit NCGO30000
the Division of Water Quality (DWQ) is forwarding herewith the reissued 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 October
15, 2007 (or as subsequently amended)_
The following information is included with your permit package:
• A new Certificate of Coverage (COC)
• A copy of General Permit NCG030000
• A copy of the Technical Bulletin for the General Permit
• Two copies of the Discharge Monitoring Report (DMR) Form
• Two copies of the Qualitative Monitoring Report Form
The General Permit authorizes discharges of stormwater, and it specifies your obligations for discharge
controls, management, monitoring, and record keeping. Please review the new permit to familiarize yourself
with all the changes in the reissued permit. Your facility has six (6) months from the time of receipt of the
permit to update your current SPPP to reflect all new permit requirements.
The first sample period of your permit begins January 1, 2013. Your facility must sample a "measureable
storm event" beginning during the periods beginning January 1 and July 1 of every year (or, if applicable,
report "No Flow," as outlined in Part III, Section E). Also, please note that Tier 3 Actions in Part II of your
permit are triggered by benchmark exceedances on four occasions beginning on the effective date of this
permit and do not count prior exceedances.
The more significant changes in the General Permit since your last COC was issued are noted either in the
Draft Permit Fact Sheet that accompanied the public notice (htt ortal.ncdenr.or web w ws su current -
notices), or in the Response to Comments / Summary of Changes and Technical Bulletin documents that are
posted on the Stormwater Permitting Unit's website with the new General Permit. Please visit
http://portal.ncdenr.org/web/wo/ws/su/ni)dessw (click on 'General Permits' tab) to review that information
for your specific General Permit carefully.

Some of the changes include:
Part II:
• Section A: The Stormwater Pollution Prevention Plan (SPPP) section, if applicable, has been updated
to the most current language of our permits. Additional conditions for specific industry sectors have
been added to the SPPP requirements in some cases.
• Sections B, C. Failure to perform analytical Stormwater monitoring may result in the Division requiring
that the permittee begin a monthly sampling scheme.
• Sections 8, C: A lower TSS benchmark of 50 mg/I for HQW, ORW, PNA and Tr Waters applies to these
more sensitive waters.
• Sections B, C. The monitoring parameter Oil & Grease (O&G) has been replaced by the parameter
Total Petroleum Hydrocarbons (TPH) for vehicle maintenance areas, and in some cases, other
analytical monitoring requirements.
• Sections B, C, D: Inability to sample due to adverse weather must be recorded in the SPPP, or in
separate on -site records if your General Permit does not require an SPPP. Adverse weather is defined
in the "Definitions" section of the permit.
• Sections B, C. The term "Representative Storm Event" has been replaced by "Measurable Storm
Event." A measurable storm event is defined in the permit.
• Section D: If the permittee fails to respond effectively to problems identified by qualitative
monitoring, DWQ may require the permittee to perform corrective action.
Please review Parts III and IV to understand the Standard Conditions of your new NPDES General Permit,
including Compliance and Liability, Reporting, Monitoring and Records requirements; Operation and
Maintenance obligations; and Definitions. Please note that all samples analyzed in accordance with the terms
Of this permit must be submitted to the Division on Discharge Monitoring Report (DMR) forms available on
the Stormwater Permitting Unit's website above. DMR forms must be delivered to the Division no later than
30 days from the date the facility receives the sampling results from the laboratory. Also note that existing
permittees do not need to submit a renewal request prior to expiration unless directed by the Division.
Your coverage under the General Permit is transferable only through the specific action of DWQ. This permit
does not affect the legal requirements to obtain other permits which may be required by DENR, nor does it
relieve the permittee from responsibility for compliance with any other applicable federal, state, or local law,
rule, standard, ordinance, order, judgment, or decree. If you have any questions regarding this permit
package, please contact the Division's Stormwater Permitting Unit at [phone].
