Subject: NPDES Permit Issuance
Permit No. NCO041696
Lake Rhodhiss WWTP
Facility Class IV
Burke County
Dear Mr. Morse:
Division personnel have reviewed and approved your application for renewal of the subject
permit. Accordingly, we are forwarding the attached NPDES discharge 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 October 15,
2007 (or as subsequently amended).
The final permit authorizes the Town of Valdese to discharge municipal wastewater from the
Lake Rhodhiss Wastewater Treatment Plant to Lake Rhodhiss (Catawba River), a class WS-IV&.B CA
water in the Catawba River Basin. The permit includes discharge limitations/or monitoring for flow,
BOD5, ammonia nitrogen, total suspended solids, dissolved oxygen, total residual chlorine, fecal
coliform, total nitrogen, total phosphorus, copper, selenium, silver along with other parameters.
The City-of Valdese is probably aware that Lake Rhodhiss.has been placed on the NC 303d
list for impaired waterbodies due to high pH in the lake. Because of this pH impairment, a Lake
Rhodhiss Management Action Plan has been recommended and a total maximum daily load (TMDL)
will be developed by the Division. Due to the impact of nutrients*on the lake, the TMDL will specify
the reduction of nitrogen and phosphorus inputs from point and nonpoint sources.
Because of the impaired status of Lake Rhodhiss, it has been recommended by the US
Environmental Protection Agency, that the current loading of total nitrogen and total phosphorus
discharged be frozen upon expansion to the flow of 10.5 MGD. Therefore, based on calculations
using the 2007 - 2009 average discharge flows and nutrient concentrations, nitrogen and
phosphorus mass limitations have been placed in the 10.5 MGD effluent page for the Lake
Rhodhiss WWTP. This strategy would cap the nutrient inputs from the potential expansion of

Valdese discharge and other expanding direct discharges to Lake.Rhodhiss until the TMDL is fury
developed. At 10.5 MGD, the total nitrogen mass load limit will be 146,659 lbs/year and the total
phosphorus mass load limit will be 33,200 lbs/year. Special conditions A.5. and A.6. have been
added to the permit regarding the nutrient limits and calculation of nutrient loads.
The TMDL may recommend that effluent limitations for nutrients be incorporated into the
2014 -2015 permit renewal for other dischargers that contribute to the impairment. DWQ is also
considering rulemaking efforts that would establish technology based nutrient limits which would
be applied to lakes that are impacted by excessive nutrient loading. It would be prudent for the
Town to begin preparations and budgetary planning for pending nutrient reductions.
In order to support and provide the necessary data for the TMDL effort, additional effluent.-
monitoring for total nitrogen and total phosphorus will be required during this permit cycle for .
Valdese's Lake Rhodhiss facility. North Carolina regulation 15A NCAC 2B.0508 (b)(2) allows "...
additional tests and measurements... with such frequency as are determined by the Director to ...
adequately monitor constituents of the waste discharge and their effect upon the receiving
waters...".
The following modifications included n the March 30th draft remain in the final permit.
• An effluent page for 3.5 MGD has been added to the permit based on the reduced
wasteflow into the facility. Effluent pages for flows of 7.5 MGD and 10.5 MGD remain
in the permit.
• Effluent monitoring for total nitrogen and total-phosphorus has been modified from
monthly to weekly to provide data for the development of the Lake Rhodhiss TMDL.
• The instream monitoring frequency for dissolved oxygen, temperature and pH has
been reduced to.once per week during June,July, August and September and once _
per month during the remaining months of the year.
• The following procedure has been implemented by DWQ: Total residual chlorine (TRC)
compliance level changed to 50 ug/1. Effective March 1, 2008, the Division received
EPA approval to allow a 50 ug/l TRC compliance level. This change is due to
analytical difficulties with TRC measurements. Facilities will still be required to report
actual results on their monthly discharge monitoring report (DMR) submittals,-but for
compliance purposes, all TRC values below 50 ug/1 will be treated as zero. A footnote
regarding this change has been added to the effluent limitations page in the permit.
• Based on the reasonable potential analysis conducted on effluent data in discharge
monitoring reports and priority pollutant analyses, the following changes are
recommended:
o At 3.5 MGD, total silver will be monitored quarterly, in conjunction with the whole
effluent toxicity test, based on the results of the reasonable potential analysis.
o At 7.5 and 10.5 MGD, total copper and total silver will be monitored quarterly, in
conjunction with the whole effluent toxicity test, based on the results of the
reasonable potential analysis.
o At 3.5 and 7.5 MGD, total selenium will be monitored quarterly based on the
results of the reasonable potential analysis.
o At 10.5 MGD, a selenium limit of 75 ug/1 will be added based on the results of the
reasonable potential analysis which indicated the potential to exceed the water
quality standard.

o The phenols limit will be dropped (for all wasteflows) based on the results of the
reasonable potential analysis. There was no reasonable potential shown to exceed
the water quality standard instream. Division guidance recommends that phenols
monitoring continue in the pretreatment long term monitoring plan.
o Please note that during the annual effluent pollutant scan that mercury should be
sampled using EPA Method 1631E.
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 written
petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the
office of Administrative Hearings, 6714 Mail Service Center, Raleigh, North Carolina 27699-6714.
Unless such a demand is made, this permit shall be final and binding.
Please take notice that this permit is not transferable. The Division may require modification
or revocation and reissuance of the permit. This permit does not affect the legal requirements to
obtain other permits, which may be required by the Division of Water Quality, or permits required
by the Division of Land Resources, Coastal Area Management Act, or any other Federal or Local
governmental permits may be required.
If you have any questions or need additional information, please contact Ms. Jacquelyn
Nowell at telephone number [phone].

RE:COMMENTS ON DRAFT NPDES PERMIT NCO041696 FOR LAKE RHODHISS WWTP
Dear Ms. Nowell,
Our purpose for providing comments on the Division of Water Quality's intent to renew the NPDES permit for Lake
Rhodhiss WWTP in Burke County, NC involves the protection of the Catawba River at Lake Rhodhiss. Lake Rhodhiss
serves numerous recreational uses and as a drinking water supply for communities in the upper Catawba River basin.
Because Lake Rhodhiss WWTP discharges into this 303(d)listed waterway,Catawba RWERKEEPER`Foundation, Inc.
(hereinafter CRF)seeks to halt the continued degradation of this body of water and safeguard the recreational use of
this waterway by citizens.Therefore,CRF respectfully submits these comments on behalf of the Catawba River,its
watershed,and CRF members.
CRF is a non-profit environmental conservation organization and has been registered as a 501(c)(3)in North Carolina
since 1997.CRF's mission is to advocate for the protection,enhancement and enjoyment of the entire Catawba River
watershed.With approximately 1200 members throughout the 17 counties that span the Catawba River Basin in North
Carolina,CRF is the only local river conservation and advocacy organization focused solely on the protection and
enhancement of the Catawba River.
Violations
Over the past years, Lake Rhodhiss WWTP has experienced effluent compliance issues at its wastewater treatment
facilities as publicly-viewed at EPA's Enforcement&Compliance History Online. During the past five years,this facility
has received multiple Letters of Violation from NCDENR regarding effluent violations of pH,Total Suspended Solids(TSS)
and Phenolics. Furthermore, Lake Rhodhiss WWTP has received five Notices of Violation that have recently
corresponded with compliance evaluations.
CRF is particularly concerned about this facility because these effluent violations continue to(1) inundate a waterway
listed on the 303(d)list with pollutants beyond the allowable limits, (2)stress and expose biological life to an
environment of increased organic chemicals,suspended solids and
variable pH concentrations and (3)violate the rights of citizens in North Carolina to safely traverse and expose
themselves to the waters in the Catawba River at Lake Rhodhiss as well as safely use this water of the state for fishing
and a drinking water source.

Nutrients
To elaborate, Lake Rhodhiss was placed on the 303(d) list for high pH,a by-product of algal productivity. While the
Division should be commended for its efforts within this draft permit to monitor and limit nutrient loading(Total
Nitrogen and Total Phosphorus)from this facility upon complete expansion to 10.5 MGD,Section A(3),these calculated
nutrient loading limits should be added to Sections A(1)and A(2). According to a study conducted by Carolina Land &
Lakes RC& D, Inc.,Lake Rhodhiss WWTP is the second largest point source load of Phosphorus into Lake Rhodhiss at
10.27 tons yr'1. Acting within a lentic ecosystem, phosphorus plays a primary role as the limiting nutrient to algal
productivity and should therefore be limited. Not only would this provide better reporting and insight into to the
nutrient loading of Lake Rhodhiss, but this is addition would provide potentially undeniable assurances that Lake
Rhodhiss WWTP is limiting its impacts on the nutrient loading of an impaired waterbody.
Organic Compounds
In addition to this impaired listing,fishes in waterbodies downstream in the Catawba River Chain of Lakes have been
found with elevated levels of polychlorinated biphenyls. These findings resulted in the release of fish consumption
advisories in the Catawba River from Mountain Island Lake southward. Despite these recent announcements and
subsequent loss of the ability of North Carolinians to safely consume fish from the River,this draft permit proposes to
remove limits on phenols from Lake Rhodhiss WWTP based on the results of the reasonable potential analysis.
CRF disagrees with this proposed permit modification for three reasons:
(1) Phenolic limit violations during current permit: Lake Rhodhiss WWTP has exceeded its phenolics
limits multiple times,as high as 224%,in its current permit cycle.The most recent violation occurred as
recently as one year ago in March 2011.
(2)Organic chemical compound and chlorine interactions: Lake Rhodhiss WWTP uses chlorine to
disinfect its treated effluent. Because chlorine is a highly interactive element with organic compounds,
the environment for the creation of potentially harmful residual organic compounds exists.
(3) pH and TSS variability:The variability in the pH (high)of Lake Rhodhiss also can play a potential role in the
chemical interactions of the constituents in the effluent from Lake Rhodhiss WWTP. In addition to the pH
variability,Lake Rhodhiss WWTP's violations of TSS limits in its current permit cycle provide a potential
attachment site and route for chlorinated organic compounds to enter and pollute the Catawba River at Lake
Rhodhiss. These violations could potentially be creating a source of pollution in the Catawba River basin that
has remained unchecked.
For these reasons,CRF does not believe this permit should be modified to remove phenolic monitoring from its permit
nor should a limit for phenols be removed. CRF believes that Lake Rhodhiss WWTP should test for PCBs in its effluent
and in the sediments and fish residing in Lake
Rhodhiss near its effluent outfall during the annual priority pollutant analysis. These suggested permit changes and
monitoring requirements would assure that Lake Rhodhiss WWTP is not contributing to a problem that has recently
resulted in fish consumption advisories in the Catawba River basin and the loss of use of River fish by North Carolinians.
Conclusion
For these reasons,CRF believes that the Division of Water Quality should not approve the draft NPDES permit
NC0041696 as proposed.The biological,chemical and recreational integrity of this waterway should be protected and
maintained with the implementation of this permit; and at this time, CRF does not feel that the immediate renewal of
NC0041696 would,in fact,do so.
The Division should not grant this permit renewal as proposed because of this facilities' record of violations regarding
several parameters of its permit and its inability to uphold the integrity of its existing permit and of the waterway to
which it discharges.Therefore,CRF requests that the following modifications to the draft permit occur:
2

1. Addition of TN and TP loading limits to Sections A(1)and A(2).
2. Re-instatement of the phenols limit and monitoring requirements.
3. Effluent monitoring for PCBs during annual priority pollutant analysis.
4. PCB monitoring in sediment and fish near effluent discharge location in Lake Rhodhiss.

SUMMARY OF FACILITY INFORMATION
The Town of Valdese has requested renewal with modification of the NPDES permit for
Lake Rhodhiss Wastewater Treatment Plant. The existing WWTP with a design flow of
7.5 MGD discharges into Lake Rhodhiss, a class WS-IV & B CA water. The class
denotes use as a water supply, primary recreation and critical area waterbody. The
current permit has tiered effluent pages of 7.5 and 10.5 MGD. The Town has
requested an additional effluent page with a lower flow of 3.5 MGD because of the loss
of major water users and the potential for additional water losses. Average flow in
2010 was 2.09 MGD, which is 28% of capacity at 7.5 MGD. At the new flow page of
3.5 MGD, 2.09 MGD is 60% of capacity. Valdese is currently discharging at the 7.5
MGD effluent page but because of the lower wasteflow into the plant, the Town is
asking to discharge at the lower 3.5 MGD. The plant's wastewater is municipal and
industrial and serves the Towns of Valdese, Drexel, and Rutherford College in
addition to Burke County for a total-of nearly 8,200 persons.
Existing limits and/or monitoring requirements in the permit were for BOD5, TSS,
NH3, DO, fecal coliform, pH, total residual chlorine, phenols, and chronic toxicity.

Valdese currently operates a 7.5 MGD wastewater treatment plant consisting of the
following treatment units:
- Influent pump station
- Bar Screen
- Grit removal
- Primary clarifiers
- Aeration basins
- Secondary clarifiers
- Chlorination
- Dechlorination
- Gravity sludge
- Thickeners
- Residual centrifuges
- Residuals composting operation
The treatment plant has a Pretreatment Program and a Long Term Monitoring Plan
(LTMP) as it receives flow from the following noncategorical Significant Industrial
Users (SIUs) and Categorical Industrial Users (see Table 1).
Table 1. Significant Industrial Users discharging to the Valdese Lake Rhodhiss

Valdese Weavers #1 0.625 MGD
Valdese Weavers #2 0.600 MGD
Valdese Weavers #3 0.300 MGD
*Valdese Textiles no longer SIU
It is recommended that the existing pretreatment program continue to be
implemented during the next permitting cycle. All parameters monitored in the
LTMP should continue to be monitored during the renewed permit cycle.
RECEIVING STREAM
The receiving stream is Lake Rhodhiss (Catawba River) and is classified WS-IV & B CA
(critical area) in the Catawba River Basin. Lake Rhodhiss is listed on the 2010 303d
list for impaired streams for high pH. Based on this impairment, a Lake Rhodhiss
Management Strategy has been developed for point source and nonpoint inputs. A
portion of the strategy as included in the draft 2010 Catawba River Basinwide
Management Plan has been included below:
Lake Rhodhiss Nutrient Management Action Plan
Due to the high pH impairment of the lake, a Lake Rhodhiss Nutrient Management
Action Plan was developed. Excessive nutrients withil�the lake have been shown to be
originating from both point and nonpoint sources. Below are selected portions of the
action plan for point sources and how they will be addressed during the coming five
year period.

Point Source Action Plan
Beginning in November 2008, an optimization study was conducted with three out of
the four major NPDES dischargers into Lake Rhodhiss (Marion, Morganton and
Valdese). The Asheville Regional Office is working closely with these three facilities to
ensure pilot studies and resulting implementation efforts are completed by end of
summer 2011. The above facilities are participating voluntarily with the goal of
reducing effluent total phosphorus concentrations to 2 mg/L.
Average Annual effluent TP and TN at the Lake Rhodhiss WWTP
Yearly TP TN
Averages (mg/1) (mg/1)
2007 3.0 5.8
2008 2.7 6.8
2009 2.9 6.0
thru 3/2010 1.3 4.1
Four facilities (Marion, Morganton, Lenoir and Valdese WWTPs) will be required
through their NPDES permit to monitor their effluent weekly for nitrogen and
phosphorus. Permits will also include the requirement to conduct
upstream/downstream monitoring for nutrients monthly during the period of the
study for these facilities. This monitoring will provide clear nutrient contribution data
from each facility by determining what the levels are in-stream above and below each
facility's discharge pipe. It should be noted that since Valdese discharges directly into
Lake Rhodhiss, upstream and downstream monitoring of nutrients will not be
required.
A TMDL for Lake Rhodhiss will be developed by the DWQ Modeling/TMDL Unit during
this upcoming planning cycle for the pH impairment. Due to the fact the lake is co-
limited for nutrients, the TMDL will specify total nitrogen and total phosphorus
reductions from point and nonpoint sources.
Limits consistent with the TMDL will be incorporated into the 2014 and 2015 permit
renewals for the affected facilities. Any early reductions achieved through the pilot
studies and implementation efforts will be taken into consideration when permit
limits are established.
EPA Recommendation for Lake Rhodhiss dischargers
Because of the impaired status of Lake Rhodhiss, it has been recommended by
the US Environmental Protection Agency, that the current loading of total nitrogen
and total phosphorus discharged be frozen.upon expansion to the flow-of-10.5 MGD.
Therefore; based on calculations using the-2007 - 2009 average discharge flows and
nutrient concentrations; nitrogen and phosphorus-mass_limitations-have-beer-/placed
in the 10.5 MGD effluent page for the Valdese-Lake Rhodhiss WWTP . This strategy
would cap the nutrient inputs from the potential expansion of Valdese discharge and
other expanding discharges to Lake Rhodhiss until the TMDL is fully developed. At
10.5 MGD, the total nitrogen mass load limit will be 146,659 lbs/year and the total
phosphorus mass load limit will be 33,200 lbs/year. Special conditions A.5. and
A.6. have been added to the permit in regards.to the nutrient limits and calculation of
nutrient loads. ;

TOXICITY TESTING:
Current Requirements: At 7.5 MGD, Chronic Toxicity P/F at 4.8%; Jan Apr Jul Oct;
At lower flow tier of 3.5 MGD, Chronic Toxicity P/F at 2.8%; Jan Apr Jul Oct
Upon expansion to 10.5 MGD, Chronic Toxicity P/F at 6.6%; Jan Apr Jul Oct
Since the last renewal in February 2006, the facility has passed all quarterly toxicity
tests (18).
Recommend renewal of toxicity tests of 2.8%, 4.8%, and 6.6%, respectively, at
3.5 MGD, 7.5 and 10.5 MGD.
COMPLIANCE SUMMARY:
Overall, compliance with limits in the permit has been achieved by the facility during
this permit cycle. There were some exceedances of the TSS limit in 2007 and 2008,
in addition to phenols limits in 2008 and 2009. Notices of violation were issued by
the Division. Since that time, TSS and phenols limits have been met by the facility.
In 2007, the facility was issued a notice of violation for improper operation of the
facility. A civil penalty of approximately$4200 was assessed and paid by the facility.
Since that time, the facility has been rated as compliant during subsequent annual
compliance evaluations in 2008, 2009, and 2010.
INSTREAM MONITORING:
Current Parameters: Dissolved Oxygen, Temperature
Recommended Parameters: Dissolved Oxygen, Temperature
Upstream: 100 ft upstream from the outfall
Downstream: 1 mile below the outfall at NCSR 1001
DMRs list upstream site as : Valdese Water Plant, and downstream site as: Castle
Bridge
Valdese has asked for the removal of instream monitoring. DWQ will recommend a
modification in the monitoring frequency at the sites. The facility can monitor once
per week from June, July, August and September and once per month during the
remaining months of the year. Instream monitoring for TP and TN will not be
required.
A review of instream data in the Lake Rhodhis during the critical summer months of
June, July and August in the years 2007,2008, 2099, and 2010 showed that the DO
standard of 5 mg/1 was being met both upstream and downstream of the WWTP.
There were no extreme variations in upstream and downstream temperature.
The pH data collected showed the maximum pH values in the summer ranged from
9.0 to 9.8: Maximum upstream pH values ranged from 9.0-9.4 S.U.(with one high
value of 9.8 SU). The maximum downstream values ranged from 9.2 to 9.5 S.U.
REASONABLE POTENTIAL ANALYSIS
Data submitted in discharge monitoring reports and PPAs from 2007 through 2009
were evaluated and a reasonable potential analysis (RPA) was done to determine
whether efflueaf limitations or monitoring should be included in this permit renewal.
The following-parameters were submitted in the DMRs: arsenic, cadmium, chlorides,
chromium, copper, cyanide, lead,mercury, molybdenum, nickel, selenium, silver,
zince, total phenolic compounds, sulfates, antimony. The RPA and effluent data is
attached to the factsheet and the results are summarized below:

• At 3.5 MGD, total silver will be monitored quarterly, in conjunction with the
whole effluent toxicity test, based on the results of the reasonable potential
analysis.
• At 7.5 and 10.5 MGD, total copper and total silver will be monitored quarterly,
in conjunction with the whole effluent toxicity test, based on the results of the
reasonable potential analysis.
• At 3.5 MGD and 7.5 MGD, total selenium will be monitored quarterly based on
the results of the reasonable potential analysis.
• At 10.5 MGD, a selenium limit of 75 ug/l will be added based on the results of
the reasonable potential analysis which indicated the potential to exceed the
water quality standard.
• The phenols limit will be dropped (for all wasteflows) based on the results of the
reasonable potential analysis. There was no reasonable potential shown to
exceed the water quality standard instream. Division guidance recommends
that phenols monitoring continue in the pretreatment long term monitoring
plan.
• RPA results for all other parameters monitored showed no reasonable potential
to exceed the allowable concentrations due to the high dilution with discharge
into Lake Rhodhiss.
• RPA results for mercury: all values submitted were below detection, therefore
no limits or monitoring will be required in the permit. Valdese should continue "
to monitor for mercury in the pretreatment program.
PROPOSED CHANGES:
The following modifications have been made to the permit:
• An effluent page for 3.5 MGD has been added to the permit based on the
reduced wasteflow into the facility. Effluent pages for flows of 7.5 MGD and
10.5 MGD remain in the permit.
• New TRC footnote regarding 50 ug/l detection has been included.
• Effluent monitoring for total nitrogen and total phosphorus has been increased
from monthly to weekly to help provide adequate data for the formation of the
Lake Rhodhiss TMDL.
• Monthly instream monitoring for total nitrogen and total phosphorus has been
added to the permit to help provide data for the Lake Rhodhiss TMDL that will
be produced by DWQ. This additional instream monitoring for TP and TN will
be in effect until this renewed permit expires in 2015.
• At 3.5 MGD, total silver will be monitored quarterly, in-conjunction with the
whole effluent toxicity test, based on the results of the reasonable potential.
analysis.
• At 7.5 and 10.5 MGD, total copper and total silver will be monitored quarterly,
in conjunction with the whole effluent toxicity test, based on the results of the
reasonable potential analysis.
• At 3.5 and 7.5 MGD, total selenium will be monitored quarterly based on the
results of the reasonable potential analysis.
• At 10.5 MGD, a selenium limit of 75 ug/l will be added based on the results of
the reasonable potential analysis which indicated the potential to exceed the
water quality standard.
• The phenols limit will be dropped (for all wasteflows) based on the results of the
reasonable potential analysis. There was no reasonable potential shown to
exceed the water quality standard instream.' Division guidance recommends
that phenols monitoring continue in the pretreatment long term monitoring
plan.
• Please note that during the annual effluent pollutant scan that mercury should
be sampled using EPA Method 1631E.

Site
Mountain Island Lake in Gaston and Mecklenburg Counties
Pollutant - Mercury, Polychlorinated Biphenyls (PCBs)
Date Issued - January, 6, 2011
Advisory
Elevated levels of PCBs have been found in channel catfish; therefore, health
officials are recommending that people avoid eating channel catfish in these
waters. PCB testing in largemouth bass from Mountain Island Lake was
indeterminate; however, previous studies have shown that largemouth bass in all
waters of North Carolina have elevated levels of mercury. Pregnant women,
nursing women, women who may become pregnant, and children under age 15
should not eat any largemouth bass. To guard against mercury exposure and
potential PCB exposure, other people should not eat more than two meals a
month of largemouth bass from this lake.
Please also see statewide and regional mercury advisories.

Please also see statewide and regional mercury advisories.
Polychlorinated Biphenyls (PCBs)
Polychlorinated biphenyls are mixtures of up to 209 individual compounds known
as congeners. PCBs have been used as coolants and lubricants in transformers,
capacitors and other electrical equipment because they don't burn easily and are
good insulators. The manufacture of PCBs was stopped in the U.S. in 1977
because of evidence they build up in the environment and can cause harmful
health effects. Products made before 1977 that may contain PCBs include old
fluorescent lighting fixtures and electrical devices containing PCB capacitors, and
old microscope and hydraulic oils.
PCBs can still be released to the environment from hazardous waste sites; illegal
or improper disposal of industrial wastes and consumer products; leaks from old
electrical transformers containing PCBs; and burning of some wastes in
incinerators. PCBs do not readily break down in the environment and thus may
remain there for very long periods of time. In water, a small amount of PCBs may
remain dissolved, but most stick to organic particles and bottom sediments.
PCBs also bind strongly to soil. PCBs are taken up by small organisms and fish
in water. They are also taken up by other animals that eat these aquatic animals
as food. PCBs accumulate in fish and marine mammals, reaching levels that may
be many thousands of times higher than in water.
Studies of people exposed to PCBs in the workplace suggest that some people
may experience irritation of the nose and lungs, gastrointestinal discomfort,
changes in the blood and liver, and depression and fatigue. Persons exposed to

high levels of PCBs may develop an acne-like rash on their skin (chloracne). In
some studies women who ate large amounts of fish contaminated with PCBs had
babies that weighed slightly less than babies from women who did not have
these exposures. Babies born to women who ate PCB-contaminated fish also
showed abnormal responses in tests of infant behavior. Some of these
behaviors, such as problems with motor skills and a decrease in short-term
memory, lasted for several years. Other studies suggest that the immune system
was affected in children born to and nursed by mothers exposed to increased
levels of PCBs. Some studies of workers indicate that PCBs were associated
with certain kinds of cancer in humans, such as cancer of the liver and biliary
tract. In animal studies rats that ate food containing high levels of PCBs for two
years developed liver cancer. The EPA and the International Agency for
Research on Cancer(IARC) both identify PCBs as probably carcinogenic to
humans.
Mercury
Mercury is an odorless, silver-white metal that is found naturally in the
environment. Industrial sources such as coal burning industries, municipal and
medical waste incinerators and chlor-alkali plants release mercury into the air.
That mercury is spread through the air and may be deposited in water. Mercury
builds up in fish tissue and other aquatic life. As bigger fish eat smaller fish, the
bigger fish get higher levels of mercury. That's why many advisories related to
mercury warn against eating large fish like bowfin or largemouth bass or ocean
fish like shark or king mackerel.
Exposure to high levels of mercury can damage the brains of unborn children
and young children. Prenatal exposure to mercury can affect the way children
think, learn, and problem-solve later in life. That's why many of the advisories are
stronger for pregnant women and young children who are more sensitive to the
toxic effects of mercury.
In adults, the earliest obvious signs of mercury poisoning are numbness of lips,
fingers or toes, fatigue and blurred vision.

030831 6305'010 1/B
Per application rec'd 8/31/2009, the Town is making requests for the renewal. Notes
thatn there have been no changes made to the plant since the last permit renewal and
there are no plans for upgrading. The Town's requests include:
I) Language be included in the new permit in regards to TRC compliance level
change to 50 ug/1.
2) An additional flow tier be added to the permit for 3.5 MGD along with the
existing 7.5 and 10.5 MGDs.
3) Removal of upstream and downstream sampling requirements.
4) Decrease phenol monitoring frequency to monthly or quarterly.
Ann review
Facility serves approx. 8200 persons, with Burke Co., Valdese, Drexel and Rutherford
College.
Avg. flow last year- 2.09 MGD—facility has a design capacity of 7.5 MGD, the average
flow is at 28%capacity. If new flow page of 3.5 MGD is added, the capacity would be
60% .
Disinfection is chlorination/dechlorination.

ValdeOs eNC, 28690 R E V E D

PO!nIT c L BRANCH
Dear Permit Writer:
The Town of Valdese is formally requesting renewal of NPDES Permit#NC0041696, for the Lake
Rhodhiss WWTP. No changes have been made at the plant since the last permit renewal and there are
no plans for upgrades in the near future. Included with this letter are one signed original and two copies of
EPA Form 2A application. A narrative of the Biosolids management plan is included as requested.
In conjunction with the renewal, the Town of Valdese asks that language be included in the new permit in
regards to TRC Compliance Level change to 50ug/l. This would replace the addendum dated May 1,
2008 from DWQ.
The Town would like to request an additional tier be added to the permit. Currently, the plant has a 7.5
MGD and 10.5 MGD permit. At current and projected flows, neither permitted limit is realistic for the plant
at least through the next permit cycle.We would like to formerly request a 3.5 MGD permit in addition to
the existing permit limits. The Town could easily work under the 3.5 MGD permit through the end of the
permit cycle. This is due to loss of major water users since the last permit renewal and the possibility of
further loss of major water users. This is flow that will not be replaced anytime in the near future or ever,
as there are no new textile mills being opened in the United States, and this area has also seen a
decrease in population since the last permit cycle.
The Town would also like to request the complete removal of the upstream and downstream sampling
requirements. These samples have no scientific usefulness and from my understanding are not utilized by
the State in anyway. The sampling basically equates to wasted resources(gas, labor, paper, money)
these are the type of things the State and all government agencies need to be aware of, even more so in
these hard economic times.As a professional, I do not see any value in doing sporadic shoreline
sampling up and down the river with no coordination between sites.
The Town; based on current permit results feel that Phenol monitoring frequency should be decreased
from weekly to monthly if not quarterly on the 7.5 MGD permit.Also, Phenol monitoring should only be
done as part of the long term monitoring on the new 3.5 MGD permit.
The Town will forward the August Toxicity results once we receive them from the lab. If there is any other
information that is needed please contact us. The staff and I will be happy to assist with any questions or
data that the State needs.

PO Box 339
Valdese NC, 28690
Permit#NC0041696
Permit#WQ0001990
Solids generated at the Lake Rhodhiss Wastewater Treatment Plant are thickened in two gravity
thickeners, and then centrifuged, the solids cake is trucked to the onsite compost area where they are
blended with bulking agents (ground limbs, wood chips, and leaves). Windrows are then created from the
blend. The windrows are aerated a minimum or 14 days, where temperatures are monitored and
recorded. Each windrow must be over 40 degrees Celsius,with an average temperature of 45 degrees
Celsius, and have 3 consecutive days of temperature of 55 degrees Celsius or higher. Once these
requirements are met, the windrows are broken down and placed in a static pile for an additional 30 days
or curing. The composting area is large enough to hold 8 windrows, storage for approximately a year's
worth of product, as well as storage for bulking agent and a mixing area.
The compost produced at the plant is Class A Bio-solids and is given away to the public with an
information pamphlet. Before any piles/windrows are released, bacterial testing is performed to ensure
that it meets the Class A designation and a"residuals"analysis is conducted on quarterly basis(permit
specified). Composted solids not meeting any of the above requirements is re-introduced into the
composting process. Solids collected from the grit chambers and bar screens are conveyed directly into a
dumpster and hauled to the landfill by a third party(GDS).

Gregg-Daily monitoring requirements kick in with a Grade 4 W WTP rating, which is a permitted flow>
2.5 MGD. Thus, any permit flow sheet above 2.5 MGD receives the same monitoring frequency. If you
are currently averaging 2 MGD,I would not consider an interim phase of 2.25 MGD, since you would
already be close to 90% of permitted fl ich would kick ou into the next phase. Let me know the
basis for your other proposed flows 3.75 MGD and 4.99 MGD, and we can take another look at it at
permit renewal.

Mr. Behuck, aej��� AWa1J d�I >J 1' +Fi7W.1 .
I just wanted to touch base with you regarding modifications Valdese will be seeking on our next
permit.
I would like to request a tiered permit in the future. Currently, we have a 7.5 MGD and 10.5 MGD
permit in place. The 10.5 MGD would only come into effect after certain upgrades to the plant.
The new permit levels that we will be requesting will be somewhat contingent upon the sampling
requirements that coincide with the various flow levels.
For instance,what is the difference in monitoring for 2.5 MGD as opposed to 3.5 MGD.
More than likely I will seek a tiered permit for 2.25 MGD, 3.75 MGD, 4.99 MGD and then keep the
existing levels 7.5 MGD and 10.5 MGD.
As it stands now Valdese has lost a great deal of flow, through the closing of textile mills, and
could possibly lose more in the near future. The average flow is currently 2.0 MGD.
Any input or guidance from you or your office that could expedite the process would be greatly
appreciated.

NOTES FOR 2009/2010 PERMIT RENEWALS/CATAWBA BASIN
TO: Permit File NC0041696- Valdese (assigned to Jackie)
Pennit File NC0026573- Morganton (assigned to Jackie)
Permit File NCO023981- Lenoir(assigned to Julie)
These 3 permits are for discharges that ultimately flow into Lake Rhodhiss, which has
nutrient issues. Based on a conversation with Modeling/TMDL on 10/16/2009, we
(Jackie, Tom) agreed to add the following conditions to the permit renewal:
• Increase effluent monitoring for nutrients (TN, TP) to weekly.
• Cover Letter
o Indicate the additional effluent nutrient monitoring is to support future
TMDL efforts.
o Indicate the permittee should prepare and budget for future nutrient
reductions.
o Indicate a nutrient TMDL is on the TMDL schedule.
o Indicate there are also rulemaking efforts to establish technology-based
limits for TN and TP, which would be applied to lakes that are impacted
by excessive nutrient loading.
