RE: Stormwater Sampling Results - North Carolina General Permit No. NCG030000
Certificate of Coverage Number NCG030412
2nd Semi -Annual 2018 Storm Water Sampling
Mann -Hummel — (Former Wix Filtration) Allen Plant
2900 Northwest Blvd., Gastonia, NC 28052
ARM Project No. 12-4003-14
Ms. McAllister:
In accordance with the North Carolina Department of Environment, and Natural Resources (NC DENR)
stormwater discharge permit, ARM collected the second semi-annual stormwater samples at the
referenced facility on November 12, 2018.
The samples consisted of one stormwater grab sample from the facility stormwater outfall location, and
the sample was collected during the rain event in Laboratories clean, pre -preserved, laboratory -prepared
sample bottles. The sample was then delivered to Prism, Inc., which is a North Carolina -accredited
analytical laboratory. The sample was analyzed for oil and grease, total suspended solids (TSS), copper,
lead, zinc, and total toxic organic compounds (volatile and semi -volatile organic compounds) via EPA
Methods 624 and 625, per the permit requirements.
The attached Table 1 provides a summary of the analytical results (also attached), total flow, and total
rainfall. All parameters were below the permitted range benchmarks in the sample, except for the
exceedances of copper and zinc. The pH was performed in the field upon sample collection; was within
the recommended holding time of 15 minutes; and showed results within the permitted range benchmark
value of 6.0-9.0. The Stormwater Discharge Monitoring Report (SDO), which also shows the analytical
results for the outfalls are attached. During sample collection, qualitative monitoring of certain
parameters was performed and the Qualitative Monitoring Report for each outfall is attached.
ARM appreciates the opportunity to provide environmental services to Mann -Hummel. As required by the
stormwater permit, please sign the second page of the SDO and then forward the report to the NC
DENR-Central Files at the Division of Energy, Mineral, and Land Resources at the address shown on
page 2 of the Stormwater Discharge Monitoring Report. Please call us at 704-369-0621, if you have any
questions.
Sincerely,

' 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.
'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, Section B, Table 1 to identify the especially sensitive receiving water classifications where the more protective benchmark applies.
'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."

All permits require qualitative monitoring to be performed during a "measurable storm event."
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 DEMLR
Regional Office.

" Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfail.
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.
" 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."

Note: Results must be reported in numerical format. Do not report Below Detection Limit, BDL, <PQL, Non -detect, ND, or other similar non -numerical
format. When results are below the applicable limits, they must be reported in the format. "<XX me/L". where XX is the numerical value of the detection
limit, reporting limit, etc. in mg/L.

All permits require qualitative monitoring to be performed during a "measurable storm event."
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 DE1N4LR
Regional Office.
By this signature, I certify that this report is accurate and complete to the best of my knowledge:
