Dear Mr. Manner:
In accordance with the application for a discharge permit received on April 5, 1995, the
Division is forwarding herewith the subject NPDES permit. This permit is issued pursuant to
the requirements of North Carolina General Statute 143-215.1 and the Memorandum of
Agreement between North Carolina and the U.S. Environmental Protection Agency dated
December 6, 1983.
In a letter dated February 14, 1996, John Phillips, P.E., requested that the discharge be
allowed to remain at the existing location without implementation of a limit for ammonia.
After review of existing instream and effluent data and after consideration of the alternative
discharge point proposed by Mr. Phillips in an earlier request, the Division has decided to
grant the request for this facility to remain at the current location without ammonia limits. The
rationale for this decision is based on the combination of several factors. First, this is a
seasonal discharge which (under normal meteorological conditions) does not travel to a
flowing (i.e., perennial) stream. Secondly, a benthic macroinvertebrate study performed in
the receiving stream indicated that this discharge was not causing stream degradation. Finally,
although the pipe could be relocated downstream of the existing location to allow for better
dilution of the effluent, such an action would place the pipe closer to the Mitchell River itself
with no increase in waste treatment from current levels. Given that this system is classified as
an Outstanding Resource Water, the Division does not believe (at present) that such a
relocation would be preferable. However, after reviewing the self -monitoring data submitted
for this facility, it would appear that nitrification (reduction of ammonia) is occurring most of
the time, but BOD5 concentrations approach the 30 mg/1 monthly average limit. The Roaring
Gap Club should perform an evaluation of the existing wastewater treatment system to
optimize the removal of the carbonaceous oxygen demand. Any improvements to the septic
tank -sand filter system would be beneficial to the receiving waters and can normally be made
at a relatively low capital cost. A report on the evaluation and optimization of the treatment
system should be su - a em e ional OTtice by August ,
If any parts, measurement frequencies or sampling requirements contained in this permit
are unacceptable to you, you have the right to an adjudicatory hearing upon written request
within thirty (30) days following receipt of this letter. This request must be in the form of a

the conclusion was that the original discharge point was better, and the facility
NC0038997 BAB
would be allowed to continue discharge there without ammonia limits. WLA
summary is attached.
• Discharge is seasonal. 1997 flows were significantly higher (as high as 0.0136
MGD), prior to upgrades. Flows typically < 0.005 MGD in '98.
• During operation, TSS normally < 10 mg/1 (slightly higher on average in '98), and
fecal typically <2/100 ml.
• pH and temperatures are fine.
• DOs range from 3-5.5 mg/l in '97; slightly higher in '98 (4-6 mg/1). BOD5
normally < 5 mg/1 in '97, but increased in `98— ranging 10-30 mg/l more often.
• Ammonia levels are low, typically < 1 mg/l in '97. In '98, levels still fairly low,
but slightly higher (< 1-3.6 mg/1).
General Comments:
Facility's treatment did not seem to improve significantly in '98, but overall
performance is okay. Facility might be able to meet 2/4 limits for ammonia, but
not consistently, and this issue is a sore one, given previous objections byy the
facility. Because of the discharge situation (basically to the ground), it is probably
feasible to renew without ammonia limits as last time, but what about the equity
issue? We are requiring other dischargers to zero flow streams to meet these limits,
normally with a compliance schedule of about two years...
Discussion with Dave G., 2/2/99: Since the Mitchell is an ORW, leaving the
discharge at the current location is the better choice. This discharge is also only
seasonal, which can increase difficulty with consistent treatment. Facility invested
significant effort into completing the required optimization study and
modifications to the plant, so it is reasonable to again grant a renewal without
ammonia limits.
Discussion with Mack Wiggins (prev. permit writer): Facility was originally given
choice between ammonia and tox. limits, and it chose ammonia (hence the request
for relocation in order to have higher limits). Since discharge was to a "valley area"
and not directly to the UT, and because of optimization work, the zero -flow policy
was not applied in this case.
Per Steve Pellei's 12/7/98 Memo regarding nutrient monitoring in the Yadkin
basin, this facility should be given quarterly TN and TP monitoring.
Expiration date to be assigned to this permit is December 31, 2003.

The WWTP is located in a mountainous region and consists of a septic tank, dual sand
filters with chlorination and dechlorination. The facility provides service to a small resort area
consisting of a few residences and a restaurant. Typically the facility does not discharge
November through April. After treatment the effluent is discharged from a pipe onto the ground
(mountain side). The discharge is not to a stream in the conventional since of the word. The
discharge is more to a heavily vegetated "valley -like" area of the mountainside which conducts
storm water but remains dry during non rainy periods. If you were to call this "valley -like"
receiving topology a stream it would be estimated to have a 7Q10=0 cfs and a 30Q2=0 cfs. This
was what was done in the 1993 WLA (#7272) and as a result the zero flow policy was added to the
permit. The current permit calls for the removal of the discharge or BOD5=5 mg/L and NH3-N=2
mg/L limits depending on the results of the alternatives analysis. In this WLA (#8428) the facility
is exploring the possibility of relocating the discharge such that the effluent is piped directly to the
UT instead of running over ground. The UT at the proposed relocation site is estimated to have a
S7Q10=0.05 cfs and a 30Q2=0.11 cfs. Allen Smith (WSRO), as well as a former ORC have both
stated that the effluent discharged onto the "valley -like" area is absorbed into the ground before it
ever reaches the UT in most cases. Given the extra in -ground treatment the effluent receives before
entering the UT as ground water, it is recommended that the outfall not be relocated so
as to discharge effluent directly into the UT. It is the region's opinion that the current treatment
and discharge scenario at the present loading rate is not resulting in any significant environmental
impact. It is my opinion that relocating the outfall to the proposed location would be more
detrimental to the UT than the present situation.
It is questionable as to wheth,r the S7Q10 flow at the relocation site is positive. Generally,
a flow of less than 0.05 cfs is considered zero flow. I am going to consider the flow positive (see
WLA notes for calculations and explanation). However, the discharge cannot be modeled
considering the non steady state intermittent -type discharge from the dosing bell septic tank. Given
the very low flow nature of the UT, as well as its B-trout ORW classification, advanced tertiary
limits for the relocated discharge are recommended.

Advanced tertiary limits are recommended given the B-trout OWR classification and the low flow
nature of the stream (SQ10=0.05 cfs).
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.
No parameters are water quality limited, but this discharge may affect future allocations.

1996
On February 20, 1996, I met with Hal Transou, ORC, and ]ay Manner, General
Manager, of the Roaring Gap Club (NPDES Permit No. NC0038997). We took a
measuring device with us as we walked the length of the discharge drainage area. The
results are as, follows:
420' - from discharge pipe to first signs of water. This is a small spring with
minimal flow; such a small flow, that no reliable sampling could be done from this spring
system.
750' - from discharge pipe to first appreciable amount of water where samples
might be collected.
1400' - from discharge pipe to where the water in the drainage basin connects to
another positive flow stream.
It should be noted that this is a steep gradient with thick undergrowth. If an
upstream and a downstream sampling is required it will easily take 1-1 /2 hours to perform
the sampling. The undergrowth gets even thicker where the two stream systems converge
so we measured where, in reality, the sampling will be done (due to accessibility) and it
was 20' Upstream from the stream convergence and 88, Downstream from the
convergence. Hopefully, monitoring frequency will be Monthly and not Weekly.
If you have any questions or concerns, please contact me at the WSRO. If you
would like a site visit, we would gladly accommodate - but you might want to wait until
Spring.

There are no management strategies for the Mitchell River or it's tributaries that would
require stricter limits on existing dischargers. There are very few freshwater ORW's that
have additional management strategies beyond the minimum (no new dischargers or
expansions, & stormwater), and they can be found in 15 NCAC 2B .0225. I am assuming
this outfall is being moved to a different point on the UT and not being moved to a point
draining to Mitchell River for the 1 st time.

Liz,
I might not have given you enough info earlier. This is an existing facility moving their
outfall. RIght now they have a BOD5=30mg/L. Are there any management strategies which
would require stricter limits, or is the only stategy just no new or expanding dischargers.

Andy, It doesn't have any additional management requirements other than the standard
management strategy for freshwater ORW's- No new dischargers or expansions to existing
dischargers are permitted (and some stormwater stuff which, if you need, let me know). Liz

Liz,
I'm working on a WLA for a facility that wants to discharge into a UT to the Mitchell River
in Alleghany Co. The stream class is B-trout ORW. Do we have any management strategies
for ORW streams in the Yadkin Basin (03-07-02)?
Thanks
