This memorandum is in response to the attached letter and your re-
quest for its review. Reanalysis of the wasteload allocation indicates
that a DO limit is not necessary at a permitted flow of 0.0175, as in the
draft permit. With regard to the fecal coliform limit: since the 7Q10 is
0.1 cfs, inadequate dilution is available to remove the fecal limit. Total
phosphorus has been removed from the WLA based on the Director's recent
decision regarding xistin dischargers less the 0.05 mgd. A wasteload
approval form is att ed.

RE: Willow Oak Acres MHP
NPDES Permit NC0060259
Rockingham County
Comments to Draft Permit
The following comments on the proposed NPDES permit for Willow
Oak Acres MHP are presented on behalf of the owner Mr. O. L.
Vogler, Jr.:
1. It does not appear that upstream and downstream monitoring
requirements are applicable to this discharge. As you 6.0 •
should be aware, this is a very small discharge relative to
the stream flow. The existing permit, which was issued
11/1/84, did not require upstream/downstream monitoring. It
is our understanding that under the current monitoring rules
upstream/downstream sampling is only required for a "water
quality limited segment". It does not appear that this
segment meets the definition that it is a segment where it
is known that water quality does not meet applicable water
quality standards or is not expected to meet them even after
the application of minimum treatment requirements".
The location of the stabilization pond discharge to the
point of discharge into Little Troublesome Creek is
approximately 800 feet. This distance will make it very
difficult Mr. Vogler to collect the upstream/downstream
samples. It is also very unlikely that any significant
benefit will be derived by the DEM from this additional
information.
For -these -reasons it is requested that upstream/downstream
monitoring not be a part of the final permit conditions.
2. The current NC limitation rules for waste stabilization ponds
with flows less than 2.0 mgd state that effluent limitations

or coliform bacteria and pH shall be imposed only if
necessary to maintain compliance with applicable water
quality standards. There has been no information presented
that shows this to be the case.
For this reason it is requested that fecal coliform and pH
not be included as part of the effluent limitations on the
the final permit.
Your consideration of the above comments to the proposed NPDES
permit is appreciated.
Very truly yours,
Evander H. Rowell, PE
