Permit: NCG030486 Owner - Facility: A 0 Smith Wafer Systems
Inspection Date: 10/25/2017 Inspection Type; Technical Assistance Reason for Visit: Routine
Inspection Summary:
The inspection was a result of a request for monitoring relief.During my last inspection I recommended installing silt logs
around outfall 003 and resampling. That was completed but TTS still exceeded 100 mgll.Based on this inspection I
recommended that they surface clean the drainage area to outfall 003, refresh the inlet protection and resample during the
next rain event. Monitoring relief will be reevaluated after the sample results from the surface clean are received.

Re: A.O. Smith Water Systems, General Permit: NCG030000,
Certificate of Coverage: NCG030486
Dear Storm Water Permitting Unit,
Attached please find information for our most recent stormwater sampling event as a follow-up
to your site visit and meeting, on May 23, 2017 with A.O. Smith at the Wa cr Systems facility
located at 4302 Raleigh Street in Charlotte, NC. Even with recent and planned storinwater
management improvements, we have determined that the benchmark values for zinc and
copper within our current permit are non -attainable due to 0e1 tside influences that are out of
our control. We therefore request that the facility be allowed to resume semi-annual
mollltoring.
As you requested, the most I-CCent results (summarized in the table on the following page)
included use of a filter sock at Outfall 003, samples for pH and zinc at downspout A and Lhe
bucket (baseline sample), and regular permitted parameter sampling at Outfalls 002 and 003.
The pH values for the bucket and downspout were lower than the outfalls, so it is unclear
whether roof runoff is a cause of elevated zinc levels from that source. The filter sock appeared
to have limited impact on TSS or zinc removal at Outfall 3; however, one would assume that
over time TSS, at minimum, would be reduced With continued use of a filter sock. Please advise
whether use of a filter sock should continue at Outfall 3 and whether a similar device should be
installed at Outfall 002.

' Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
z For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
3The total precipitation must be recorded using'data from an on -site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
A See General Permit, Table 3 identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
5 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA
Effluent Guidelines for the facility subject to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11; for semiconductor
manufacture use the definition as found in 40 CFR 469.12; for electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray

Zahid,
hope your 2017 is off to a great start. I'm following up regarding the stormwater monitoring work we're doing for
General Permit Number NCG030000, Certificate of Coverage Number NCG030486 for the A.O. Smith facility located at
4302 Raleigh Street in Charlotte, North Carolina. We discussed late last year that we would reconvene in March 2017 to
go over the stormwater sampling results. We have collected three months of data to date; however, we have identified
high levels of zinc in runoff from an adjacent industrial site that may be influencing our results and would like to get one
more month of data to confirm these exceedances before we discuss our findings with you. Assuming we get a sampling
event in March, is it okay to have a conference call between NCDEQ, Mecklenburg County, and A.O. Smith sometime in
April?
Also, do you have recent sampling results for metals for industrial facilities near the A.O. Smith Charlotte facility that you
could share with us so we can see if they are having similar results to what we have experienced? We don't need facility
names, we're just interested in the range of zinc, copper and lead levels to compare with ours.
Best regards,
Mark

1 Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
z For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
3The total precipitation must be recorded using data from an on -site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
° See General Permit, Table 3 identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
5 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA
Effluent Guidelines for the facility subject to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11; for semiconductor
manufacture use the definition as found in 40 CFR 469.12; for electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray
tube manufacture use the definition found in 40 CFR 469.31),

Facilities that incorporate a solvent management plan into the stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring
may be waived. The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General
Permit. For those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(TTO), I certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or
stormwater runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the
solvent management plan included in the Stormwater Pollution Prevention Plan."

General Permit NCG030000, Certificate of Coverage NCGO30486
Dear Stormwater Permitting Unit;
We respectfully submit the enclosed original and one copy for each of the Stormwater Discharge Outfall
Monitoring Reports for the A.O. Smith Water Systems facility under General Permit Number
NCG030000, Certificate of Coverage Number NCG030486. This submission is for the sormwater
discharge sampling period Year 2, Period 1, 2014, Tier Two response monthly monitoring events for the
months of January, February, March, and June 2014. During these four months of this year, we were unable
to obtain samples from qualified storm events either due to weather conditions or events occurring
outside of our normal business operating hours. We are therefore submitting the enclosed DMRs
checked for "No Flow" during these months when qualified storm events were unable to be sampled.
Please note that we have submitted DMRs for monthly sampling for the months of April and May 2014,
with the April sample event also serving as the semi-annual sampling event for the first half of 2014
(Year 2, Period 1, Sample 3). We will continue to conduct monthly sampling as required until either we
obtain three consecutive sample events with results below benchmark values or until we receive
notification in writing from NCDENR waiving the monthly sampling requirements. We will also
continue semi-annual sampling as required by our permit.
If you have any questions or comments regarding the enclosed Stormwater Discharge Outfall
MonitoryWeport (DMR) submissions, please contact us at your convenience. Thank you.
Sincer I

1 Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
Z For sampling periods with no discharge at any single outfali, you must still submit this discharge monitoring report with a checkmark here.
3 The total precipitation must be recorded using data from an on -site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
See General Permit, Table 3 identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
5 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA
Effluent Guidelines for the facility subject to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11; for semiconductor
manufacture use the definition as found in 40 CFR 469.12; for electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray
tube manufacture use the definition found in 40 CFR 469.31).

Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring
.� may be waived. The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General
Permit. For those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(TTO), I certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the Stormwater or areas which are exposed to rainfall or
stormwater runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the
solvent management plan included in the Stormwater Pollution Prevention Plan."

Dear Ms. Harris:
Enclosed is a copy of the Follow-up Compliance Evaluation Inspection (CEI) report for
the inspection conducted at the subject facility on August 5, 2008, by Ms. Erin Hall of Charlotte -
Mecklenburg Storm Water Services. This inspection was conducted as part of a cooperative
working agreement between Mecklenburg County and the Division of Water Quality. In
addition, the inspection was conducted on behalf of the City of Charlotte in compliance with the
City's NPDES Permit, NCS000240, Part II Section H. Thank you for your assistance and
cooperation during the follow-up inspection.
The follow-up inspection found that Water Systems Industries has implemented the
corrective actions as stated in'the permittee's response letter dated July 7, 2008. The corrected
actions include:
• the addition of a list of significant spills occurring during the past three years to
the Stormwater Pollution Prevention Plan (SPPP),
• documentation that the SPPP has been reviewed and updated,
• updating of the USGS location map to include accurate latitude and longitude
coordinates for the points of discharge,
• updating of the site map to include the percentage of each drainage area that is
impervious and a narrative description of the potential pollutants,
• documentation that future qualitative and analytical monitoring will be conducted
by Inenco, Inc. (Mooresville, NC), and
• improvement in the housekeeping around Building A and the Maintenance Area.
The enclosed follow-up inspection report should be self-explanatory; however should you
have any questions concerning this report or have any questions regarding your permit, please do
not hesitate to contact Ms. Allocco of this Office at [phone].

location map did not include accurate latitude and longitude coordinates for the
discharge points and whether the receiving stream was impaired or located in a
watershed for which a TMDL had been established. In addition, the site map did not did
not include the percentage of each drainage area that is impervious or a narrative
description of the potential pollutants that might be present in the stormwater discharge
from each outfall. The SPPP did not document the occurrence of spills on site in the

Industrial Operations/City of Charlotte Stormwater Ordinance Review
Building A —
This is the manufacturing building and all processes involved with water tank production are conducted within this
building. All floor drains are routed to the facility's pretreatment system (permitted under a Charlotte -Mecklenburg Utilities
Pretreatment permit that expires in 2009). before it is discharged to the sanitary sewer system. A loading dock is located
to the west of the building. Tank partsicomponents as well as containers of chemicals, paints, and solvents are unloaded
at this location. An air compressor was observed outside under cover adjacent to Building A on the east side. No staining
was observed in this area. A large open doorway is located on the east side of the building. A significant amount of
staining was observed on a concrete pad outside of this doorway. Some staining was also observed on the gravel
adjacent to the concrete pad. Another large open doorway is located on the south side of this building. A significant
amount of staining as well as an oily residue was observed on a concrete pad outside of this doorway. Forklift tracks were
observed in this area. It appeared that forklifts going in and out of the building from this doorway were tracking the oily
residue outside. The oily residue appeared to be coming from a machine within the building immediately inside the
doorway.
The housekeeping practices within the outside areas of the doorways should be improved. Recommendations include
putting oii-dry on the floor around machines to decrease the chance of the oil residue getting tracked outside by orklifts or
have forklifts enter and exit Building A via another doorway such as the loading dock area.
Maintenance Area —
The maintenance area is located on the southwest side of Building A. The majority of maintenance supplies are stored
inside under cover. This includes machines, tools, and chemical products. A small work area was observed outside on a
concrete pad adjacent to the main maintenance area. A moderate amount of staining was observed in this area. Per
facility personnel, areas throughout the facility are swept on a daily basis. This also includes removing and properly
disposing of used oil -dry on the ground.
Paint Shed —
The paint shed is located to the east side of Building A. It consists of a concrete pad that is covered, but not enclosed. A
small berm surrounds the concrete pad. The concrete pad is sloped so that if a spill occurred it would flow towards the
center of the pad. The paint shed is used to store 55-gallon polyethylene and metal drums of paints, cleaners, hydraulic
of#, lubricants, used oil, and used oil -dry. Drums are labeled and stored on pallets. Global Environmental is used to pick up
waste products. They are contacted on an as needed basis or if a spill occurs.
Buildings B and C —
Final products are stored within these two buildings. No chemicals are stored in either building. A loading dock is located
to the northeast side of Building C. Final product is loaded from here and shipped out via tractor trailer trucks. No staining
was observed in the loading dock area.
Open -top Dumpsters —

Five open -top dumpsters were observed on site. These include two for scrap metal, one for cardboard, one for wooden
pallets, and one for general waste products. These are all located at the rear of the facility. They are picked up by different
outside companies on an as needed basis. A hopper was observed at the rear of Building A. Per facility personnel,
hoppers are taken inside at the end of each day and brought back out the following day.

Comment. The SPPP contains a USGS location map, but it lacks accurate latitude
and longitude coordinates for the points of discharge and does not identify whether the
receiving stream is impaired or located in a watershed for which a TMDL has been
established as required by the general permit issued in November of 2007. The SPPP
contains a detailed site map, but does not include the percentage of each drainage area
that is impervious or a narrative description of the potential pollutants that might be
present in the stormwater discharge from each outfall. According to facility personnel,
no spills have occurred during the past three years, however this was not documented
in the SPPP.

Comment: Stormwater is collected by a main underground concrete stormwater pipe
that leads from a conveyance ditch located at the south of the property along a railroad
right-of-way. Stormwater then flows north-northwest through the facility's property via
this underground concrete stormwater pipe. The facility has two catch basins on site.
One is located to the north of Building B (Outfall 002) and the other is located northwest
of Building C (Outfall 001). Both catch basins collect stormwater and discharge it to this
main underground concrete stormwater pipe. Stormwater eventually discharges to Little
Sugar Creek approximately 0.5 miles north of the facility.

RE: Notice of Deficiency — Storm Water Compliance Evaluation Inspection
State Industries — Water Systems Division
Dear Ms. Allocco:
This letter is intended to respond to the June 23, 2008 Notice of Deficiency that State
Industries received as a result of a storm water compliance evaluation inspection
conducted by Ms. Erin Hall of the Charlotte — Mecklenburg Storm Water Services. A
number of the deficiencies noted during this inspection related to our Storm Water
Pollution Prevention Plan (SWPPP) that was reviewed by Ms. Hall during her
inspection. It should be noted that during the time of Ms. Hall's inspection, State
Industries was in the process of updating its SWPPP to comply with the terms and
conditions of the recently reissued general storm water discharge permit NCG030000
that became effective on November 1, 2007. Our revision of the SWPPP has now been
completed, and we are confident that our current SWPPP adequately addresses the
concerns raised by Ms. Hall. In accordance with permit NCG030000, this document is
available for review by the agency staff during normal business hours.
With respect to the qualitative and analytical monitoring requirements, our current
SWPPP contains a section that describes the monitoring program which we have
developed to comply with these requirements. We are in the process of contracting with
an outside firm to collect the required semi-annual samples for analytical monitoring
purposes, and should have these arrangements finalized in the near future. It is our
intent to have this outside firm also conduct the qualitative monitoring required by the
general permit. We understand that we are required to submit the analytical monitoring
results to the DENR on Storm Water Discharge Outfall Monitoring Report form SWU-
245-031308 within 30 days of receiving the sample results. We also understand that the

I. -
results of the qualitative monitoring must be documented on Storm Water Discharge
Outfall Qualitative Monitoring Report form SWU-242-020705 and kept on -site.
Finally, we reviewed Ms_ Hall's observations and recommendations regarding the
tracking of oily materials outside with our maintenance and production personnel. We
have stressed to them the importance of eliminating or minimizing the opportunities for
oil to be tracked to the outside environment. It is our intent to closely monitor the areas
identified by Ms. Hall and improve housekeeping as part of our day-to-day operations.
We trust this response adequately addresses the deficiencies noted in the storm water
compliance evaluation inspection. Should you have any questions regarding this
response, please feel free to contact our environmental coordinator, Ms. Lottie Harris at
704-597-8910.
Sincerely,
State Industries — Water Systems Division

The National Pollutant Discharge Elimination System (NPDES) program was established under the federal
Clean Water Act and then delegated to the Division of Water Quality for implementation in North Carolina. The
NPDES permitting program for stormwater discharges was established in 1990. Phase I focuses on site and
operations planning to reduce pollutant sources_
Through the NPDES permitting program industrial facilities that fall into one of the subject ten categories are
required to obtain permit coverage under a general permit or an individual permit, depending upon the
facilities SIC code and the industrial activity occurring at the facility. There are currently 19 active general
stormwater permits in North Carolina. One condition that is applicable to both the general permits and
individual stormwater permits is the requirement to develop and implement site -specific comprehensive
Stormwater Pollution Prevention plans (SPPP). These plans are required to include a comprehensive
evaluation of the site and operations to reduce pollutant sources and prevent pollutant discharge.
Copies of the general permits and accompanying documents can be accessed from the following webpage:
http://portal. ncdenr.org/web/wq/ws/su/npdessw#General_Permits_NPDES. Permit text, technical bulletins,
discharge monitoring forms, and a Notice of Intent [which is the application for coverage under a NPDES
General Stormwater Permit] can be found on this website.
The following items are a subset of permit requirements and are listed to assist you and help bring your
attention to certain permitting issues, process and condition requirements of your permit. Please see the
above mentioned website to obtain a copy of the permit so you may fully comply with all the conditions therein.
Failure to properly comply With conditions of the permit, like those bulleted be.low, is a violation(s) of
the permit and subject to civil penalty assessment(s) of up to $25,000.00 per day.
• Industrial facilities that fall into one of the subject ten categories are required to obtain permit coverage
under a general NPDES stormwater permit or an individual NPDES stormwater permit
• All persons desiring to have facilities covered by a General Permit must register with the Division of
Water Quality (DWQ) by filing of a Notice of Intent (NOI) and'Applicable Fees.
• This Notice of Intent (NOI) must be submitted and a Certificate of Coverage issued prior to any
discharge of stormwater associated with the industrial activity, process wastewater, and/or mine
dewatering.
• Once the Notice of Intent is received, DWQ will review and determine whether a Certificate of Coverage
(COC) may be issued. If this Certificate of Coverage is issued the facility is covered by the General
Permit. That is, the permittee is authorized to discharge stormwater, process wastewater, and/or mine
dewatering pursuant to the type of General Permit until the permit expires or is modified or revoked.
• Any other point -source discharge to surface waters of the state is prohibited unless it is an allowable
non-stormwater discharge or is covered by another permit, authorization, or approval.
• There are currently 19 active general permits. Permit conditions vary accordingly; however, most of the
permits have the following condition requirements (you must read your entire permit to ensure full
compliance):
o Development and compliance with the Stormwater Pollution Prevention Plan
o Collection, reporting, and recording of Analytical Monitoring
