100 Watts Rd. DWR SECTION
Spindale, NC 28160
To Whom It May Concern:
Due to the 2nd 2019 stormwater analytical results, in which the copper result indicated the second
consecutive exceedance of the permitted benchmark, this exceedance triggered a Tier'I'wo
response per the stormwater permit and translated to monthly monitoring being required until
three consecutive results are below the benchmark values or within the benchmark range. In
accordance with the North Carolina Department of Environment and Natural Resources INC
DENR) stormwater discharge permit, ARM Environmental Services. Inc. collected the first'fier
Two stormwater samples at the referenced facility on December 17. 2019 as a result
The Stomiwater Discharge Monitoring Report (SDO). which also shows the analytical results ibr
the outlall is attached. Please contact Tiffany Crosby, Sr. EHS Engineer via phone (910) 865-
6235 or email tiffany .crosbynawattswatec.com with any questions.
Sincerely,
Brad Bowen

' Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
'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.
4 See General Permit, Section B, Table 1 to identify 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).

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."

Total Event Precipitation (inches):
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. —

The following sample was diluted due to the nature of the sample matrix: UL18087-001. The LOQ has
been elevated to reflect the dilution.
The continuing calibration verification (CCV) associated with sample UL18087-001 recovered Endrin
Aldehyde above the upper control limit. The sample associated with this CCV is non -detect for the
affected analytes; therefore, the data has been reported.
