Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
This facility has had no limit violations in the past 2 years. The Rich Fork area is a potential
problem area for low D.O.'s. Instream data taken by the facility does not appear to be reliable;
there is no seasonal fluctuation in temperature or D.O., so there is no way to accurately assess the
impact of this discharge. Other facilities within the area have been given the NH3-N/tox choice, so
Auman's Mobile Home Court will also be given the choice.
Upon renewal for the Yadkin basinwide management plan, the Rich Fork area will be re-evaluated
and Auman's permit limits will most likely become more stringent.

Limits Changes Due To:
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
Parameter(s) Affected
NH3-N/tox choice
_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.
