H&H Project No. IME.003
Dear Madam/Sir:
IMET Alloys (IMET) is submitting the enclosed hard copy of the semi-annual stormwater
Discharge Monitoring Report (DMR) for the site referenced above in accordance with the
industrial stormwater permit (NCG200516).
The result of the analysis for copper (0.0101 mg/1) was above the permit allowable benchmark
concentration (0.010 mg/1) for outfall 001. Although the copper concentration slightly exceeds the
benchmark value, the copper concentration does not appear to be attributed to site operations as
explained in the August 20, 2019 Tier II Sampling Status letter by Hart & Hickman and the
December 20, 2019 Relief from Monthly Monitoring letter by NCDEQ. IMET Alloys will
continue semi-annual outfall monitoring.
Should you have any questions or need any additional information, please feel free to contact me.
Sincerely
Mike O Ya
Chief Operations Officer
Enclosure
cc: Mr. Gregory Kanellis, Hart & Hickman (via email)

Total Event Precipitation (inches): 0.5
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.

(light, medium, dark) as descriptors: Dark Brown
3. Odor: Describe any distinct odors that the discharge may have (i.e., smells strongly of oil,
weak chlorine odor, etc.): None
4. Clarity: Choose the number which best describes the clarity of the discharge, where 1 is
clear and 5 is very cloudy: Qualitative Analysis =
(1 2 3 4 5)
S. Floating Solids: Choose the number which best describes the amount of floating solids in
the stormwater discharge, where 1 is no solids and 5 is the surface covered with floating solids:
Qualitative Analysis =
1 O2 3 4 5
6. Suspended Solids: Choose the number which best describes the amount of suspended
solids in the stormwater discharge, where 1 is no solids and 5 is extremely muddy:
Qualitative Analysis =
1 2 3 4 5
7. Is there any foam in the stormwater discharge? Yes X No
8. Is there an oil sheen in the stormwater discharge? Yes X No
9. Is there evidence of erosion or deposition at the outfall? X Yes _ No
10. Other Obvious Indicators of Stormwater Pollution:
List and describe: Small sinkholes observed near outfalls. Previously noted in semi-annual
observations. No significant changes observed.
Note: Low clarity, high solids, and/or the presence of foam, oil sheen, or erosion/deposition
may be indicative of pollutant exposure. These conditions warrant further investigation.
