Dear Mr. Smith:
Division of Water Quality (Division) personnel have reviewed and approved your application for
renewalofthe subject. permit. Accordingly, we are forwarding the attached NPDES discharge permit.
It 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 October 15, 2007.
This renewed permit reflects the following changes from the previous permit:
• The limits and monitoring requirements for total lead, dieldrin, and heptachlor were removed.
• The monitoring requirements for copper and zinc were reduced to quarterly.
• Quarterly monitoring for bis(2-ethylhexyl)phthalate was added.
• Monthly monitoring and limits were added for total nickel.
• A new footnote for total -chlorine residual (TRC) was added, which allows sample results up to 50
pg/L to be considered in compliance with the limit.
Please note that the receiving stream is listed as an impaired waterbody on the North Carolina 303(d)
impaired waters list. Addressing impaired waters is a high priority with the Division, and instrearn data
will continue to be evaluated. If there is noncompliance with permitted effluent limits and stream
impairment can be attributed to your facility, then mitigative measures may be required.

The Western North Carolina Alliance wishes to submit comments on the draft NPDES permit NC0025534 for the
Hendersonville WWTP. GO, has been very helpful in getting me understand the rationale behind the permit, but
there are a few areas where we would still like to encourage additional water quality protections for Mud Creek
and the French Broad River. We are more than happy to discuss this issue in additional detail in the future,
and hope this letter can be the start of a dialogue on improving the water quality in Mud Creek.

Mr. Carson:
Copper and zinc are action -level parameters. Our policy concerning these parameters is to require quarterly monitoring,
with no limits, even if there is a potential for the WQ standard to be exceeded. We do this only in situations where the
facility has a clean record of passing its quarterly toxicity tests (like Hendersonville).
My data analysis showed that there were no actual exceedances of the standard for either copper or zinc, but that there
was a reasonable potential for that to occur at the higher (6.0 MGD) flow.

Subject: RE: Hendersonville WWTP
Gil, I wanted to ask you one quick question. The fact sheet mentions the below statement.
The analysis for copper, silver, and zinc showed a reasonable potential to exceed both
the acute and chronic allowable concentrations at 6.0 MGD flow, although for the 4.8
MGD flow, copper and zinc were below the allowable chronic number (yet above 50% of
the allowable). Since these are action level parameters, per DWQ policy, no limit will be
recommended quarterly monitoring will be required at both flows.
i

Further in the fact sheet it requires monitoring be reduced for copper and zinc from twice weekly to quarterly. I assume
that has something to do with the mentioned "DWQ policy." I am curious to know what policy this is. It would seem that
if acute and chronic concentrations would be violated (when flow is increased) then there should be a limit put in place
for these pollutants. It would also seem unusual to reduce the frequency of monitoring for these pollutants. I assume
the referenced DWQ policy is the reasoning behind these decisions, and therefore I wanted to double check with you. If
you can point me in the right direction, I would greatly appreciate it. Thanks for all your help!

the old permit due to low detection levels. Specifically the weekly
analysis for Dieldrin, Heptachlor and Lead. The dropping of
Dieldrin and Heptachlor are addressed in the cover letter and
removed from the Effluent Limitations and Monitoring
Requirements. The Lead is not listed in the cover letter or the
Effluent Limitations and Monitoring Requirements. We assume
the reduction for lead was granted.
2. Our request to reduce sampling frequency for Domestic waste,
Septage and in plant removal rates is not addressed in either the
cover letter or the permit. Are we to assume that this request has
been approved and the requested frequency is accepted?

The additional monthly sampling for Total Nickel is mentioned in
the cover letter and required in the Effluent Limitations and
Monitoring Requirements section of the permit. The limits in both
the <4.8 MGD list and the >4.8 MGD list are as mg/l for both the
monthly average and daily maximum. Are these units of measure
correct?

SUMMARY
The City of Hendersonville has requested renewal of its NPDES permit. The plant has a design
flow of 4.8 MGD, with future plans to expand to 6.0 MGD. It discharges into Mud Creek, a class
C water in the French Broad river basin. According to the application, the WWTP serves
approximately 17,600 persons in the City of Hendersonville and 1,800 persons in the Town of
Laurel Park.
Oxygen consuming limits for BOD5 = 10 mg/L (summer): 20 mg/L (winter), NH3 = 2 mg/I
(summer): 4 mg/L (winter), and Dissolved oxygen= 5 mg/I were assigned upon the expansion to
4.8 MGD, which took place in 2002. The same limits were applied at 6.0 MGD.
Hendersonville currently has an active pretreatment program with a Long Term Monitoring Plan.
There is one non- categorical SIU and two Gills. The largest SIU is General Electric Lighting
Systems, Inc, which produces component parts of outdoor area light fixtures. Its average daily
flow is 91,400 GPD.
RECEIVING STREAM
The outfall is on the listed portion of Mud Creek for impaired streams (303(d) list), for
ecological/biological integrity benthos and fish consumption. The stream has a fair
bioclassification. Several water quality initiatives and management strategies have been
introduced to improve Mud Creek.
TOXICITY TESTING
Current Requirement: Chronic Toxicity P/F @ 18 %: Feb May Aug Nov
Upon expansion to 6.0 MGD: Chronic Toxicity P/F @ 21 %: Feb May Aug Nov
NC0025534 Renewal
Page 1

COMPLIANCE SUMMARY
Overall compliance with existing limits is excellent. Only one limit exceedance was noted in
BIMS. That occurred in August 2007 and was for a 4.9 mg/L sample of dissolved oxygen (limit
is 5 mg/L).
The Hendersonville WWTP also has a clean toxicity testing record. All toxicity tests from
February 2001 to the present have been passed.
INSTREAM MONITORING
Upstream Site: above the outfall; downstream site: at NCSR 1365
A review was made of instream data during the critical months of April through October 2008-
2010. Instream DO values were well above the water quality standard of 5 mg/I upstream and
downstream of the Hendersonville WWTP. However, instream fecal coliform counts were often
above the effluent standard of 200/100 mL monthly average, both upstream and downstream of
the WWTP. It is recommended that instream monitoring be continued at the existing frequency.
REASONABLE POTENTIAL ANALYSIS:
Two reasonable potential analyses (RPAs) were performed for all monitored toxicants, one at
4.8 MGD and the other for the expanded discharge flow of 6.0 MGD. Discharge Monitoring
Reports (DMRs) from January 2008 to the end of 2010 were reviewed for evaluation of this
facility. In addition, three Priority Pollutant analyses (2008-2010) were included, as well as data
from the plant's Long Term Monitoring Plan. The results are summarized below.
• The analysis for copper, silver, and zinc showed a reasonable potential to exceed both
the acute and chronic allowable concentrations at 6.0 MGD flow, although for the 4.8
MGD flow, copper and zinc were below the allowable chronic number (yet above 50% of
the allowable). Since these are action level parameters, per DWQ policy, no limit will be
recommended. Quarterly monitoring will be required at both flows.
• Limits and monitoring will be required for total nickel, which showed a reasonable
potential to exceed the allowable chronic concentration at both flows.
• No monitoring or limits will be required for these parameters, which did not have sample
results above the detection limit or show reasonable potential at either flow: arsenic,
beryllium, cadmium, total phenolic compounds, chromium, cyanide, lead, mercury,
selenium, silver, dieldrin, and heptachlor. It should be noted that cadmium, chromium,
lead, nickel, and selenium will continue to be monitored quarterly in Hendersonville's
pretreatment LTMP.
• Regarding Bis (2-ethylhexyl) phthalate, there was one hit (14.2 pg/L) out of three data
points. This compound was also found in past PPAs, although no monitoring was
required due to its being attributed to laboratory contamination. In order to acquire more
data, and in accordance with Division policy, quarterly sampling will be required.
SUMMARY OF PROPOSED CHANGES
• Eliminated limits and monitoring for total lead, dieldrin, and heptachlor.
• Changed the monitoring frequency for total copper and total zinc from twice per week to
quarterly.
• Added quarterly monitoring for bis (2-ethylhexyl) phthalate.
• Added daily maximum and monthly average limits for total nickel
• Corrected the street address of the wastewater treatment plant.

Dear Sir.
OFFICERS:
W. BOWMAN FERGUSON
City Manager
SAMUEL H. FRITSCHNER
City Attorney
TAMMIE K. DRAKE
City Clerk
Attached is an Application for the purpose of renewal of the NPDES Permit
referenced above in accordance with 15A NCAC 2H .0105(e). The subject
permit expires on December 31 2010.
The existing permit contains weekly requirements for the pesticides dieldrin
(parameter code 39380) and heptachlor (parameter code 39410). The
analysis of these parameters has indicated nothing but non -detection levels
since the permit was issued, therefore; the City respectfully requests that
these parameters be removed from the new permit.
Similarly, the weekly requirement for lead (parameter code 01051) has had
only 2 analyses above the detection limit and the highest one was 9.7ug/1.
We would also like to request that this requirement be removed.
Currently we have a database for the quarterly analysis of domestic waste,
septage, and in -plant removal rates that dates back over a decade. We would
like to change the sampling frequency to semi-annually.

The original submission for this plant in 2003 used designed data for BOD,
TSS, and ammonia -nitrogen pollutants. This submission for 2010 used site -
specific data for all calculations. The site -specific data has also been used
for our most recent HWA.
Should you require additional information, please contact William Ashbrook
at 828-697-3057 or me at 828-233-3211.

PROCESS NARRATIVE
Process units located on site include influent pumping station with bar screens designed to
handle all raw sewage delivered by 42 inch gravity sewer, all septage received at WWTP for
treatment, and waste streams from solids handling facility, consisting of gravity thickener
supernatant overflow and belt press filtrates. Additional facilities include headworks consisting
of mechanical screening and aerated grit removal; biological treatment using an activated sludge
process utilizing fine bubble aeration with single stage nitrification; circular clarifiers; recycle
pumping station; effluent polishing using low head filters; disinfection by ultraviolet light; and
cascade aeration of final effluent prior to surface discharge to Mud Creek. Design for sludge
residuals are treated as prescribed by State and Federal requirements to Class A solid, intended
for land application. Residuals are currently disposed of in class D landfill. Capability for re -use
of treated wastewater has been incorporated into plant design.
