Facility never received zero 7010 language; it was requested during the 1994 streamline process but did not get into
permit. It looks as if the Region does not want to pursue this facility as discharge is so infrequent; consistency wise
we need to apply the same zero flow requirements to them as any other discharger even though it may not be the
most economically and environmentally feasible and efficient approach.

Region recommends reissuance since reality of situation is that no discharge has taken place since construction,

PART IV - EVALUATION AND RECOMMENDATIONS
There is no change in the operation or use of this wastewater treatment
facility or its discharge circumstances since previous staff report
recommending reissuance of NPDES Permit Number NC0060283. Comments and
recommendations contained therein are reproduced below.
The discharge from this existing facility is designed to enter a UT to Smith
Mill Creek which shows a zero 7Q10. The main stream is located approximately
150-200 feet from the discharge point on the opposite side of paved NCSR
1338. The access route to the main stream (other side of the road) is not
owned by the mobile home park. A requirement to extend this outfall line to
the main stream may meet with easement problems which would prevent
compliance with the requirement. It is important to note here that this
facility has not discharged since construction (1984-85). Also, no WQ or odor
problems have been noticed or reported to occur in this area as result of
this system.
Considering that this facility has not discharged to surface
waters since construction, it is recommended that the permit be
reissued with discharge to the UT to Smith Mill Creek as
requested.
