Limits Changes Due To: Paramewds) Affected
Change in 7Q10 data
Change in stream classification
Relocation of discharge
Change in wasteflow
Other (onsite toxicity study, interaction, etc.)
Instream data
New regulations/standards/procedures x NH3, Tox, test
New facility information
x Parameter(s) are water quality limited For some parameters, the available load capacity of
the immediate receiving water will be consumed. This may affect future water quality based
effluent limitations for additional dischargers within this portion of the watershed.
•O
No parameters are water quality limited, but this discharge may affect future allocations.

INSTREAM MONITORING REQUIR M ENTS
Upstream Location: Nantahala River approx. 50' upstream of outfall
Downstream Location: Nantahala River approx. 100' downstream of the outfall
Parameters: Temperature
Special instream monitoring locations or monitoring frequencies:
4 Temperature for trout waters shall not be increased by more than 0.5°C due to the discharge and in no Ca5c
exceed 20°C.
