Subject: Issuance of NPDES Permit NCO039578
TWSA Plant #1
Jackson County
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).
This final permit includes no major changes from the draft permit sent to you on May 21, 2008.
The Division received comments from the NC Wildlife Resources Comm ssion strongly recommending that
you consider ultraviolet (UV) disinfection for your facility. Chlorine can be acutely toxic to aquatic organisms and
forms secondary compounds that can also be detrimental to aquatic life. UV disinfection would reduce the chemical
load in your facility's effluent and reduce risks to aquatic life instream. The Commission also requested that a Staff
Member be contacted immediately in the event that treatment problems arise. You may wish to contact Mr. Dave
McHenry at [phone], ext. 24 for further details on this issue.
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 demand is made, this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. 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, the Coastal Area Management Act or any other Federal or Local governmental permit that may be
required. If you have any questions concerning this permit, please contact Sergei Chernikov at telephone number
[phone].

dubia at an effluent concentration of 1_5% at 1.5 MGD permitted flow/ 3_5% at 3.5 MGD permitted flow.
i
The permit holder shall perform at a minimum, uag rterly monitoring using test procedures outlined in the "North Carolina
Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North Carolina Phase
II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The tests will be
performed during the months of February, May, August and November. Effluent sampling for this testing shall be
performed at the NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit limit,
then multiple -concentration testing shall be performed at a minimum, in each of the two following months as described
in "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent
versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the highest concentration
having no detectable impairment of reproduction or survival and the lowest concentration that does have a detectable
impairment of reproduction or survival. The definition of "detectable impairment," collection methods, exposure regimes,
and further statistical methods are specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised -February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form
(MRA) for the months in which tests were performed. If reporting pass/fail results using the parameter code TGP3B, DWQ
Form AT-1 (original) is sent to the below address. If reporting Chronic Value results using the parameter code THP3B, DWQ
Form AT-3 (original) is to be sent to the following address:

New flow estimates were used to calculate the permit limits.
II. Summary
Two segments of the Tuckasegee River are newly listed on the draft 2008 303(d) list for
fecal coliform. According to the 2007 Little Tennessee River Basin Plan, fecal coliform
levels throughout two reaches of the Tuckasegee River are elevated. Although there are
several WWTPs in the area, levels are higher than effluent levels from the WWTPs
would indicate, which "suggests that sources other than the treatment plants are
contributing to the impairment".
In September 2006, TWSA entered into a Special Order by Consent (SOC) with the
Division allowing slightly increased BOD, TSS, and fecal coliform limits until July 2011.
During the course of the SOC, TWSA is required to meet milestones pertaining to the
planning, design, and construction of upgrades to its aging W WTP. Revised SOC was
issued on 02/13/2008.

NPDES Permit Fact Sheet - 07/30/08

TWSA Plant #1 WWTP
NCO039578
TWASA has applied for the expansion to 3.5 MGD on March 17, 2008. The EAA was
approved on May 16, 2008. The effluent limits for an expanded phase were established in
accordance with the Speculative Limit Letter of 03/01/2006.
The Division of Water Quality determined that the incremental impact of the increased
discharge will not result in contravention of applicable water quality standards or loss of
the river's designated uses. The Division concluded that expansion of the existing
treatment plant and continued discharge to the Neuse River is the most feasible
alternative.
The Division has determined that the proposed expansion is necessary to accommodate
social and economic growth in the area and that it will not result in contravention of
surface water quality standards or loss of designated uses in the receiving stream.
III. Compliance Summary
DMR Data Review
DMRs were reviewed for the period of November 2005-October 2007. A summary of
monthly average values is summarized below in Table 1. The facility is currently at a
monthly average of 61 % capacity with a maximum monthly average at 75% capacity.
TWSA had problems meeting BOD, TSS, fecal coliform, and occasionally pH limits over
the course of the permit, resulting in an agreement to enter into a SOC.

The facility is not required to perform instream monitoring due to its low industrial
contribution and the relatively high streamflow (1.53%/3.5% fWC).
RPA Analysis
RPAs were performed for the toxicants cadmium, cyanide, copper, zinc and silver for an
expanded flow. RPA indicated that changes are not necessary. Please see attached.

WET Test Results
TWSA Plant #1 WWTP
NCO039578
TWSA Plant #1 has a chronic WET testing requirement at 1.53% effluent concentration.
The facility has passed 18/19 quarterly tests administered since February 2004. The
single failure was in November 2004 and the facility passed the two consecutive tests
following that failure.
Correspondence File Review/Compliance History
TWSA has accumulated $19,750 in penalty assessments since 2005 based on numerous
violations of its BOD, TSS, pH, and fecal coliform limits. According to several
Technical Assistance Visits conducted by the Asheville Regional Office, Plant #1 is an
aging, out of date system that offers little treatment flexibility. In addition the collection
system experiences high UI which has resulted in very high flows during wet weather.
During the Technical Assistance Visits, the regional office recommended upgrades to the
collection system, clarifier, equalization basins, and digester. The facility is currently
under a SOC with specific construction milestones in order to upgrade its aging treatment
process.

SUBJECT: Tuckaseigee Water and Sewer Authority W WTP Plant # I
NPDES Permit No. NCO039578 major modification request
Jackson County
Dear Ms. Wilson:
Biologists with the North Carolina Wildlife Resources Commission (Commission) reviewed the notice
about the proposed major NPDES permit modification for the Tuckaseigee Water & Sewer Authority
(TWSA) W WTP Plant # 1 that discharges into the Tuckasegee River in Jackson County. Comments from
the Commission on this proposal are provided under provisions of the Fish and Wildlife Coordination Act
(48 Stat. 401, as amended; 16 U.S.C. 661-667d), North Carolina General Statutes (G.S. 113-131 et seq.),
and the North Carolina Administrative Code 15A NCAC 101.0102.
This W WTP was issued a Special Order Consent (SOC) because of an inability to consistently comply
with permit limits for biological oxygen demand, suspended solids, and fecal coliform. The SOC was
amended in February 2008 to allow, in part, an increase of discharge capacity by 0.6 million gallons per
day (MGD). The current proposal involves another request to increase the discharge capacity from 1.5 to
3.5 MGD. An Environmental Report (ER) was prepared in late 2007 that described proposed WWTP
improvements and the discharge increase to 3.5 MGD. In November 26, 2007 comments on the ER, the
Commission did not concur with a Finding of No Significant Impacts for the project because mitigative
measures for its direct and secondary effects on aquatic resources need to be addressed.

Tuckaseigee Water and Sewer Authority Page 2 June 9, 2008
Jackson County
The Tuckasegee River is designated an Aquatic Significant Natural Heritage Area of national significance
because of numerous rare aquatic species. It supports the federally endangered Appalachian elktoe
mussel (Alasmidonta raveneliana) and other rare species like the olive darter (Percina squamata, FSC,
NC -SC). However, water quality in the river is deteriorating because of sedimentation and other non -
point and point pollution sources. The river was recently added to the 303d List because of elevated fecal
coliform contamination.
The river is projected to have ample assimilative capacity for the proposed discharge increase. However,
the Commission is concerned that operational upsets will eventually harm rare aquatic species,
particularly if the wastewater volume increases substantially in the absence of appropriate measures to
reduce toxicity. Mussel declines have occurred downstream of the Franklin W WTP on the Little
Tennessee River in Macon County and more recently below the Burnsville W WTP on the Cane River in
Yancey County. Chlorine is acutely toxic to aquatic life and freshwater mussels are extremely sensitive
to ammonia. Therefore, ultraviolet light or ozone systems are recommended instead of chlorine and de -
chlorination systems. Ambient concentrations in the range of 0.3 to 1.0 mg/L total ammonia as N at pH 8
do not appear toxic to freshwater mussels (Augspurger et al. 2003). Wastewater treatment improvements
should employ technology that achieves these low ammonia concentrations.
If the discharge increase is permitted, then the Commission recommends that it not become effective until
the W WTP's wastewater treatment improvements, which should include the prescriptions outlined above,
are completed and it consistently complies with the original permit limits and not those amended by the
SOC. According to Mr. Roger Edwards with the Division of Water Quality's Asheville Office, any
additional discharge increase for the facility would not become effective until the SOC is resolved (June
5, 2008 personal comm.). Compliance with the actions identified in the SOC must occur by April 1,
2011. The Commission also requests that TWSA be required to contact Commission representatives and
the U.S. Fish and Wildlife Service in Asheville immediately in the event that treatment problems arise.
This would facilitate our assessment of any aquatic resource damages, assist the Division of Water
Quality with remedial actions, and help assure the safety of our field staff who routinely survey the
Tuckasegee River. Contact information has been or will soon be provided to Mr. Roger Edwards.
The Commission also wishes to take this opportunity to remind the Division of Water Quality of the need j
for a site specific management strategy for the Tuckasegee River watershed as required by 15A NCAC
02B .0110. This rule, which became effective on August 1, 2001, requires the development of strategies
for maintaining water quality in watersheds that harbor federally -listed aquatic species. The strategy for
the Tuckasegee River was supposed to be finished in March 2007, which is when the first full 5-year
basin planning cycle was completed after rule implementation. Specific mitigative measures for major
NPDES permit modifications/expansions, like the proposed TWSA Plant #1 project, should be addressed
in such a strategy.

ALTERNATIVE NO. 7: LAND APPLICATION1O T A'
i
lM08
WASTEWATER I
D6YR �'l> WARtCEE�R ZUU4A1
NDescription _ An alternative to increasing discharged flow at the current Plant No. 1 location or
seeking a new discharge permit near Cullowhee is to use the additional wastewater for
irrigation purposes through a land application permit. This alternative is similar to
alternative No. 5 but would not require tertiary treatment and would require additional
buffers from property lines, surface waters, and habitable residences. Assuming the
proposed parcel is square the property line buffers would require an additional 67 acres
be acquired beyond the 516 acres required for reuse water irrigation.
Land application of wastewater under the NCAC 15A 02T Section .0500 rules
requires similar treatment quality to the speculative limits issued for the discharge
alternative. The exception to this is an ammonia requirement of 15 mg/l which will be
met by either the SBR or extended air treatment processes considered. Similar to
Alternative No. 5 it is assumed that the irrigation system would be operated in a
conjunctive manner with the NPDES permit and no storage facilities would be required.
Land Requirements
The treatment works would be constructed on the existing treatment plant site and
would not require any additional land to be purchased. As described above this
alternative would require an area over 500 acres for irrigation of the wastewater and an
additional 67 acres of buffer area. The property would need to be purchased or utilized
based on an agreement with the property owner. In addition to the irrigated area,
easements would-be required for irrigation lines to the site.
Construction Issues
As discussed previously, the existing wastewater treatment plant No. 1 property
presents significant site challenges. These same challenges related to topography,
hydrologic features, available property, and subsurface rock material also exist for the
WWTP No. 1 upgrades included in Alternative No. 3. This alternative also may require a
Preliminary Engineering Report Tuckaseigee Rater and Sewer Authority
McGill Associates P.A. PG. 31A May 2008

culvert to be installed on the stream located at the north side of the site, requiring that
associated regulatory issues be addressed.
Environmental Impacts
Environmental impacts from this alternative would be identical to Alternative No.
3 with the addition of impacts from construction and operation of the wastewater
irrigation system. The wastewater irrigation system would require the disposal area be
cleared and maintained as an open field for operation of the sprinklers.
Cost Estimate
The costs of land acquisition and the irrigation system would be in addition to the
cost of secondary treatment outlined in the above alternatives. If property could be found
nearby and purchased by TWSA, and a conjunctive wastewater irrigation permit issued
that did not require storage facilities this would represent the lowest potential cost for this
alternative. Similar to the other alternatives the project would be constructed in two
phases. The estimated cost for this ideal situation is $27,758,000 in 2009 dollars. If the
wastewater irrigation system is non -conjunctive, requiring storage, the cost will be well
in excess of the above estimate. Based on the large difference in capital cost between
these and other alternatives and certain higher operations cost, land application will not
be considered further.

McGill Associates P.A. PG. 32A May 2008

VI. SELECTION OF AN ALTERNATIVE
A) PRESENT WORTH ANALYSIS
In order to select an alternative a present worth analysis has been performed including all
feasible alternatives. This analysis considers the initial construction costs, non -construction
"soft" costs, operations and maintenance, and salvage value at the end of the 20 year
planning period. Operation and maintenance (O&M) costs for Alternative No. 2 (Extended
Aeration) and No. 3 (SBR) should be similar, with the O&M costs associated with the SBR
alternative being slightly less than the O&M costs for the Extended Aeration alternative. The
cost of operations and maintenance is anticipated to be higher for Alternative No. 4 due to
the additional equipment required for two separate plants and operator requirements. Testing
requirements will also be duplicated in order to operate the two plants. Alternative No. 5
(Land Application of Reclaimed Water) will also experience higher O&M costs than
Alternatives No. 2 and 3 due to the additional treatment requirements, as well as the O&M
costs associated with the land application system. O&M costs were estimated based on
current costs for O&M adjusted for inflation, historical data, and increased residuals disposal
cost. Salvage values were included for all structures and yard piping assuming a 50 year life
for these components. Equipment was considered to be at the end of its useful life at the end
of the 20 year cost period. All costs were estimated in or converted to 2009 dollars for
comparison purposes. The table below is a summary of these costs and the calculated present
worth amounts for the alternatives, utilizing a 5.1 % discount rate.

B) ALTERNATIVE SELECTION
The results* indicate that Alternative No. 3 has the lowest estimated 20 year present
worth. Alternate No. 3 is also preferable due to the reduced footprint on the treatment plant
site requiring less land disturbance. The SBR treatment process will also provide a more
flexible treatment process with a higher effluent quality than the other alternatives.
Alternative No. 4 has the second highest 20 year present worth and would result in the most
environmental impacts due to the addition of a second treatment plant site. Based on this
evaluation Alternative No. 3 "WWTP No. 1 Expansion — SBR Process" has the lowest
present worth and the most positive non -monetary factors. Therefore Alternative No. 3 is the
chosen alternative.

JACKSON COUNTY WASTEWATER
TRLATTENT PLANT

Tuckaseigee Water and Sewer Authority
Sludge Management Plan
The Tuckaseigee Water and Sewer Authority in Jackson County currently treats residuals
generated by the three facilities currently owned by the Authority, plus the residuals
hauled from septic tanks located in Jackson County. Residuals generated by temporary
facilities required by the County Health Dept. to be available at new home construction
sites (porta johns) are also accepted by the TWSA for treatment.
In calendar year 2006 these residuals were totaled as follows:
TWSA Plant # 1(NC0039578)............................. _.....................215.6 dry tons
TWSA Plant # 2(NC0020214)......................................................21.8 dry tons
TWSA Plant # 3(NC0063321)......................................................1 1.4 dry tons
Septage and Porta-John trucks dumped directly into the digestor and totals were not
available for 2006, however with the addition of a septage receiving station in late 2006,
these totals will now be monitored.
Sludge from all sources is mixed and digested in an aerobic digestor with 285,000 gals of
capacity. After digestion, the waste sludge is pumped to the belt press for dewatering.
This is accomplished with a piston pump manufactured by Komline- Sanderson. The
pump is capable of pumping 100gpm of digested sludge to the belt press.
The 1.2 meter belt press is manufactured by Komline-Sanderson and produces dewatered
sludge with an average % solids concentration of 18%. Dewatered sludge cake is then
augered out of the press building to a lime pastuerization process manufactured by RDP
Company.
In this process, dewatered sludge is mixed with quick lime (CaO+) at approximately 1.5/1
lime to sludge ratio to generate enough heat and ph values to meet pathogen and vector
reduction levels specified by EPA 503 regulations. The sludge and iime are mixed and the
resulting mixture and temperatures are contained in a pastuerization vessel for a minimum
of 30 minutes to stabilize the residuals for beneficial reuse. After a 24 hour curing time to
snake sure residuals retain the ph values for suppression of vector attraction the residuals
are made available to local farmers for use as a liming agent on pastures or crops.
Because the residuals meet the requirements for a Class A "high quality" sludge there are
few restrictions on the use of the residuals. These restrictions are outlined on the form
given to all users of the product. This form also makes recommendations for application
rates and gives an analysis of the product.
