1EMORANDUM TO FILE
BY: W. E. Anderson
Environmental Engineering Technician
SUBJECT: Nantahala Village
Swain County, North Carolina
The effluent from the surface sand filter at Nantahala Village flows
to a ditch. The ditch is for the most part located within a briar patch.
Ray Carnes, Maintenance Supervisor, says that he has explored the area
during the busiest part of the season when the system was discharging and
was never able to find anything discharging to surface waters. It is ex-
tremely unlikely that any person would come in contact with the effluent
from this system.

TO: Roy Davis
FROM: Forrest Westall
Lee Fleming
SUBJECT: Nantahala Village and Hemlock Inn
Your comments concerning the two subject wasteload allocations have been
noted and reviewed. While we understand your concern for the effluent
limitations recommended for these two discharges, the basis of limitations
must still be 7-day 10-year low flow. As a result the limits which were
recommended must be included in order to be consistant with North Carolina's
water quality program.
As a matter of information,we would point out that Lhe issue of discharge
to dry streams is being reviewed by the water quality task force. It is
possible that recommendations from this group may result in program
modification that would allow the Division some flexibility in the application
of its effluent limitations.
A copy of the recommended effluent limitations is attached for your information.
If you have any questions concerning this matter, please let us know.

MEMORANDUM
TO: Roy Danis
FROM: Mark Lewis �(I� • �•
SUBJECT: Wastel oad Allocation - Nantahala Village
USGS had recently lowered the 7Q10 estimate at Nantahala Village downward
from 0.01 cfs to 0 cfs. This revision had caused the effluent limits for
Nantahala Village to go from secondary to BOD5 = 17 mg/l, NH4-N = 9 mg/l.
During a phone conversation with Heath Dobson on March 31 it was decided to
use the old 7Q10 estimate of 0.01 cfs. The resulting effluent limits are
attached. Secondary limits with an effluent D.O. of 4 mg/l is sufficient
to protect the water quality standard for D.O. Please note that because of
the "B-Trout" classification of this water it was necessary to maintain the
fecal coliform limit. Normally, a total residual chlorine limit is also
required of. facilities that discharge disinfected waste into trout waters.
However, this T-acili ty is located in close proximity to Fontana Lake. We
believe that the mixing zone likely extends to the mouth of the unnamed
tributary. Once in Fontana Lake, there should be sufficient dilution such
that the limit for total chlorine residual may be omitted for this facility.
If you have any further questions, please call.
