Subject: Speculative Limits for Town of Old Fort WWTP
NPDES Permit No. NCO021229
McDowell County
Dear Mr. Stafford:
This letter is in response to Mr. Mike Parker of the Asheville Regional Office's
request for speculative effluent limits for Old Fort WWTP's proposed expansion from 1.2
MGD to 1.5 MGD. This request has been reviewed by the staff of the Instream
Assessment Unit of the Technical Support Branch.
Please be advised that response to a speculative request does not guarantee that the
Division will issue an NPDES permit to discharge treated wastewater. In accordance with
the North Carolina General Statutes, the practicable waste treatment and disposal alternative
with the least adverse impact on the environment is required to be implemented.
Nondischarge alternatives, such as spray irrigation or connection to a regional treatment
and disposal system, are considered to be environmentally preferrable to a discharge.
Therefore, prior to submittal of an NPDES application, a detailed alternatives analysis must
be prepared to assure that the environmentally sound alternative was selected from the
reasonable cost effective options. In order to receive final permit limits, a formal
application indicating the proposed WWTP design capacity and a justification for the
facility will have to be submitted to the Division's Permits and Engineering Unit.
Based on available information, the tentative limits for conventional constituents for
the Old Fort WWTP at the expansion flow of 1.5 MGD are:
Summer Winter
BOD5 (mg/1) 30 30
NH3-N (mg/1) 2.6 6.8
Dissolved Oxygen (mg/1) 5 nr
TSS (mg/1) 30 30
Fecal Coliform (#/100ml) 200 200
pH (SU) 6-9 6-9
Chlorine (µg/l) 28 28
It should be noted that the summer and winter NH3-N limits recommended for this
plant are based on protecting the receiving stream against instream toxicity. North Carolina-
is evaluating all NPDES dischargers for ammonia toxicity following the Environmental

Letter to Mr. Stafford
page 2 -
Protection Agency (EPA) guidance to protect the waters for an instream criteria of 1 mg/l in
the summer and 1.8 mg/1 in the winter, under 7Q10 flow conditions.
The Division of Water Quality (DWQ) is requiring chlorine limits and
dechlorination for all new or expanding dischargers proposing the use of chlorine for
disinfection. The process of chlorination/dechlorination or an alternate form of
disinfection, such as ultraviolet radiation, should allow the facility to comply with the total
residual chlorine limits recommended above.
A chronic toxicity testing requirement at 32% with quarterly monitoring will remain
a condition of the NPDES permit. A complete evaluation of limits and monitoring
requirements for metals and other toxicants will be addressed at the time of formal permit
application.
DWQ is currently on its second round of implementation of a basinwide water
quality management initiative for the Catawba River Basin. Our next installment of the
Catawba River Basin plan is scheduled for publication in the year 2000 . We will attempt
to further address all sources of point and nonpoint 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 committed to high levels of
treatment technology are least likely to be affected.
Final NPDES effluent limitations will be determined after a formal permit
application has been submitted to the Division. If there are any additional questions
concerning this matter,please feel free to contact Ruth Swanek (ext. 503) or Jackie Nowell
(ext. 512), of my staff at [phone].
Sincerely,

Old Fort WWTP Spec jmn
Curtis Creek 5/15/97

ARO requests that spec limits for Old Fort @ 1.5 MGD be determined by IAU. Current
design flow is 1.2 MGD, requested in 1/95. Previous design flow of 0.8 MGD.
(Compliance system still has design flow as 0.8 MGD). Facility requested an SOC in 1/96
for flow, BOD5 and TSS, that was approved by DWQ. SOC is currently in effect and is
to be for two years from March '96 to Jan. 1998. SOC limits for BOD5=50, TSS = 225
mg/l. WLA request from Mike Parker of ARO indicated that the additional 1.5 MGD was
to be for 300,000 GPD of textile waste.
Only permit violation in the past year was for an exceedance to the TSS limit in 8/96.
Plant seems to be averaging well below the limits for flow, BOD5. SOC went into effect in
Oct. 1986. No instream monitoring required because DO min. occurs at the outfall and its
proximity to the much larger Catawba River.
Model results for 1.5 MGD :
Summer effluent limits of BOD5=30 mg/l, NH3=2.6 mg/l and DO limit=5. DO min:of
6.65 mg/l occurs at the outfall, protects for the DO standard of 6 mg/l for a trout stream.
Winter effluent limits of BOD5=30 mg/1, NH3=6.8 mg/1 and no DO limit DO min. of
7.06 mg/1 occurs at the outfall,protects for the DO standard of 6 mg/1 for a trout stream.
Recommended limits:
Summer Winter
BOD5 (mg/1) 30 30
NH3-N (mg/1) 2.6 6.8
Dissolved Oxygen (mg/1) 6 nr
TSS (mg/1) 30 30
