Limits Changes Due To: Parameter(s) 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
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.
OR
No parameters are water quality limited, but this discharge may affect future allocations.
