Dear Mayor Allison:
[DFEE HNR
Subject: Speculative Discharge Limits
NPDES Permit No. NCO049867
Town of Cleveland WWTP
Rowan County
Reference is made to the proposed increase in design flow for your NPDES permit.
As requested by David Newsome of Tate Lanning& Associates, P.C., we are hereby
supplying limits that would currently be assigned to your wastewater treatment plant if the
plant capacity were increased from 0.09 MGD to 0.26 MGD.

reproduction or significant mortality at the percentage indicated; Quarterly Test.
��
**No preliminary information regarding the potential industrial user's constime//
was provided, so limits for metals or any other non -conventional pollutants could
not be provided at this time. Before an actual wasteload allocation could be
provided, the Town would have to submit complete industrial user information,,
We would also like to bring to your attention that our instream modeling analysis has
predicted that under critical conditions (i.e. 7Q10 stream flow and all dischargers at
maximum capacity) violations of the 5.0 mg/1 instream DO standard may occur in Third
Creek. Due to the oxygen stressed conditions predicted by our analysis, future expansions
beyond the 0.26 MGD design flow could possibly receive more stringent limits.

DEM is currently planning a basinwide water quality management initiative. Our
schedule for implementation in the Yadkin River Basin is set for 1998 &1999. The plan
will address all sources of point and non point pollutants where deemed necessary to
protect or restore water quality standards. In addressing interaction of sources, wasteload
allocations may be affected. Those facilities that already have high levels of treatment
technology are least likely to be affected. The Town of Cleveland may want to consider the
implementation of this basinwide strategy in planning its WWTP expansion, as opposed to
the limits proposed here which only address localized receiving waters.
Please note that these are speculative limits and are not binding unless the limits are
part of an issued NPDES permit All information pertaining to this request has been sent to
our Central Files for storage. When you are ready to request the increase, please submit a
complete application package including fees appropriate for that point in time.
If you have any questions please contact Jason Doll at [phone].
