Inspection Summary:
Select Stainless Products, LLC is located at 11145 Monroe road in Matthews on approximately
8.3 acres. The facility fabricates custom stainless steel and wood products, primarily for use in the food service industry.
Charlotte -Mecklenburg Storm Water Services (CMSWS) has not previously inspected this facility.
At the time of inspection, Select Stainless Products, LLC was observed to be in compliance with the Mecklenburg County
Surface Water Pollution Control Ordinance. The facility has exceeded the permit benchmark for Zinc at Outfall SW-2 during
three consecutive semi-annual monitoring events and should proceed with Tiered response actions, per permit requirements.
Since facility personnel suspect the adjacent business is the source of stormwater contamination, CMSWS recommends
the facility consider conducting additional analytical monitoring to compare pollutant concentrations in runoff discharged
onto the Select Stainless property from the adjacent business to flow from the outfall that includes stormwater generated
both on -site and off -site.

Comment:
Per the facility manager, no significant spills have occurred within the previous three vears. The
facility should make an annual "notation of no spills", as per Part II, Section A, 8(a) of
the permit.
A non-stormwater discharge evaluation was documented during a facility inspection on 5/26/16.
CMSWS recommends documenting this evaluation on a separate sheet as oart of the annual
upstate or including evaluation criteria on the site insDection document to ensure this
evaluation occurs during ambient conditions.
CMSWS recommends updating the spill prevention and
response plan to include the facifitYs new maintenance su ervisor.
Em to ee training was conducted and documented on
several dates in January 2017.
The last documented stormwater Dollution prevention plan reviewluodate was conducted on
6/8/2015._ The facility should conduct and document an annual review/update of the
stormwater pollution prevention plan.

Facilities iMt 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."

1 Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
7 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.
4 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).
Permit Date: 11/1/2012-10/31/2017 SWU-245, last revised 10/25/2012

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."

' Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
2 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.
s 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).
Permit Date: 11/1/2012-10/31/2017 SWU-245, last revised 10/25/2012

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."

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

Please verify whether Qualitative Monitoring must be performed during a "representative storm

Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event." However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office.

Re: Semi -Annual Stormwater Sampling at Select Stainless Products, LOAZAJI,W)
Dear DEQ- Division of Water Quality:
Select Stainless Products, LLC (SSP) retained GTA Associates, Inc. (GTA0bencfor
-annual
stormwater sampling at our Matthews, NC facility. The sampling is requireivision o Water
Quality General Permit No. NCG030000. SSP's Certificate of Coverage N63.
GTA collected samples at the facility from the two permitted outfalls (SW-hown permit
outfalls in attached Site Drainage Map) on October 27, 2015. The results ot
(summarized in Table 1) indicate that SW-1 was in exceedance of the DEQfor both copper
and zinc, with levels of 0.134 mg/L and 1.38 mg/L respectively. SW-2 was in exceedance of the DEQ
benchmark for zinc with a concentration of 8.24 mg/L. Tier 1 tasks, as outlined in NCG03000, were
subsequently completed by SSP/GTA.
GTA also collected additional stormwater samples on November 18, 2015 in an effort to
determine the source of the exceedances. Four (4) samples were collected and analyzed for copper and
zinc. The locations of the additional sampling sites (SW-1 through S W4) are displayed in the attached
Site Drainage Map, (the labeling of these sampling sites does not correspond with the original permitted
SW-1 and SW-2). Sampling point SW-1 was selected because of its location immediately down gradient
of SSP's neighboring facility, Stronghaven Containers Company (SCC). Locations SW-2, SW-3, and
SW4 were chosen to track the metal concentrations along the southern and eastern sides of the SSP
facility. The results of the additional sampling are summarized in Table 2. The stormwater collected from
SW-1 (immediately down gradient from SCC) registered the highest concentrations of both copper and
zinc, with readings of 0.034 mg/L and 1.13 mglL respectively_
Amer analyzing the sampling results and inspecting the surrounding topography, it is SSP's
opinion that the neighboring SCC facility appears to be the primary contributor to the excessive metal
concentrations detected in the stormwater runoff. SSP intends to continue in 2016 with its semi-annual
stormwater sampling and will advise DEQ of subsequent sampling results. In the interim sho have
any quest' dlor comments following review of the attached, please do not hesitate to calIMMUN
