Summary The Town of Highlands submitted an application for permit renewal on May 6,
2002. The application that was submitted on May 6 included the request for the expansion.
The Environmental Assessment process has not been finalized and no FONSI has been
issued yet, this renewal process will not consider the expansion request. Since the
expansion request is for 1.5 MGD, they sampled and analyzed for the expanded effluent
data required in the EPA application.
Facility Description The facility consists of an influent screen, dual 0.25 MGD sequencing
batch reactor tanks, each with 7.5 HP floating mixers, gravity decanters, 2.0 HP sludge
wasting pumps; 30.0 HP blowers with coarse bubble type diffusers and motorized inlet
valves; a sludge digesting system; a 69,000 gallon post -equalization basin; a chlorine
injection tank, dual 15,700 gallon chlorine contact basins, a dechlorination tank, an
ultrasonic flow meter, a post aeration step weir and a 355 GPM dual -pump lift station.
Waste Load Allocation (WLA) The last waste load allocation was completed in 1993. The
winter 7Q10 was revised in 2000. USGS provided a revised w7Q10 based on appropriate
regression equations and the elimination of the hydroelectric facility. Previously a value of
8.0 cfs was used, the revised value is 7.45 cfs. The winter limit for ammonia will not be
changed at this time. Upon expansion of the facility the limits are based on the revised
w7Q10.
Pre -Treatment: The facility does not receive industrial wastewater.

COMPLIANCE REVIEW
Basin Plan Poor and fair benthic macroinvertebrate bioclassifications are found in this
subbasin. Non point source pollution and urban land uses are contributing for the
impairment. Downstream of Highlands the biocalssification is excellent.
DMR Instream and Effluent Data Review DMR data was reviewed from January 2000 to
September 2002. They were in compliance with all permit limits. The average flow for that
period was 0.17 MGD.
Effluent Pollutant Scan A complete effluent pollutant scan was submitted. Copper, silver,
zinc and toluene were detected.

Process Description / SBR
The ESI SBR is an activated sludge, biological nutrient removal process, based on
intermittent cycle operation.
The operation cycle is typically four hours, with two hours of air -on and two hours of air -off. For less than design
loadings the cycle can be adjusted to times that are compatible with the hydraulic and organic loading conditions that are
experienced (eg. 4.8 hour, 6 hour cycles, etc). Wet weather events are handled through a shorter high flow cycle of
operation in which hydraulic loading is high and organic loading is reduced.
Important features of the technology by comparison with other conventional constant volume aeration and clarifier
systems and generic sequencing batch reactor systems include: -
Optimisation of energy through control of metabolic activity.
Elimination of the need for secondary clarifiers and therefore a very compact footprint.
Removal of nitrogen and phosphorus nutrients without chemical addition through proper oxygen demand/supply
management.
Demonstrated containment of growth of most of the filamentous sludge bulking microorganisms through bioselector
principles.
Operation under continuous normal low loading conditions through simple cycle adjustment plus the ability to
automatically
convert operation to a high flow cycle for extended wet weather operation.
Operates with minimal internal recycle flows.
Principles of Operation
A basic SBR cycle comprises phases for: -
Fill, Aeration
Settle
Decant
During the aeration phase, the liquid volume inside the vessel increases from a set minimum operating bottom water
level in response to a varying influent flow rate. After a specific settling period the treated supernatant is removed
(decanted), using a moving weir decanter, after which the cycle is repeated. Solids wasting after settling enables
waste sludge concentrations up to 10,000 mg/L to be removed.
AERATION refers to the air -on time during which time influent is received into the basin. Multiple basin facilities
can be operated with different sequences of air -on during the nominal aeration phase. Less than design load
operation typically operates with introduction of influent but with a delay of the aeration sequence.
SETTLING refers to the initial part of the air -off phase during which time settling conditions are created in the
previously aerated basin to provide solids -liquid separation.
DECANTING occurs once the settling phase is completed. Inflow to the basin is suspended whilst it is undergoing
decanting. The moving weir decanter is motor driven from its out -of -liquid rest position to a designated bottom
water level position to decant a specified volume of overlying supernatant water (the treated effluent). The weir is
returned to its rest position after a designated period through reversal of the drive.
Biological Selector Zone
The incorporation of a biological selector distinguishes the ESI SBR from other generic SBR's. This feature ensures
biological selection of predominately floc -forming micro-organisms over all flow loadings, improving settlability of
the sludge. This allows process operation at time cycles that are less than other SBR systems with the direct result
of a more economical process design.
Cyclic Sequencing

Design load conditions are accommodated within the modular design using a nominal cycle of four hours as
follows: -
Fill -Aeration 120 minutes (A)
Settle 60 minutes (S)
Settle -Decant 60 minutes (D)
Translating to the 4 basin design, basin interaction is shown as: -
Each basin provides up to 12 hours of aeration per day. Each of the sequences as shown are internally adjustable for
each basin.
Oxygen Uptake Rate (OUR) Control
Oxygen Uptake Rate control uses dissolved oxygen measuring sensors and the complete -mix basin configuration to
provide a full-scale process respirometer. In this way, the metabolic activity of the biomass is measured within the
actual process basin and is subsequently used as a control parameter to regulate the duration of the aeration
sequence and the rate of aeration. This methodology provides a true in -basin method for the efficient use of energy.
Nitrogen and Phosphorus Removal
Nitrification and dentrification are carried out simultaneously during the fill -aeration period in the SBR process.
Biological P-removal is favoured by air -on air -off cycling which provides the oxic - anaerobic conditions required
of that process.
The mechanism described above has recently become known as Simultaneous Nitrification and Denitrification
(SND). There are several demonstrated and theoretical benefits of this approach to nitrogen removal. These include:
Lower wastewater plant effluent nitrogen concentrations
Higher nitrogen removal rates
Reduced aeration costs due to lower DO setpoint operation (oxygen transfer is more efficient at lower bulk phase
DO concentration).
Reduced aeration costs due to the possible shunting of nitrite directly to nitrogen gas rather than via nitrite.
Reduced carbon requirement for denitrification (leading to improved effluent quality on marginal wastewaters).
SND is well established in practice, however understanding the fundamental mechanisms is an active area of
research within the wastewater industry.
The combination of oxygen uptake rate control plus simultaneous nitrification/denitrification allows the ESI SBR to
function with a minimal electrical power uptake. The following chart shows typical power consumptions measured
at SBRs, compared with continuous plants.
Biological phosphorus removal is enhanced in the ESI SBR process by monitoring and controlling the oxygen
uptake rate at the end of each aeration cycle. Ensuring a high uptake rate at this stage ensures that the biomass has a
built-in reserve of stored soluble carbon (substrate) at all times. Long sludge age BNR plants demonstrate that the
depletion of these carbon stores resulted in the bacteria operating primarily in the endogenous growth phase. Under
anaerobic conditions the endogenous -phase bacteria is sluggish (analogous to lacking energy) and relies solely on
the bioavailable (soluble) COD in the influent raw sewage as carbon source to effect release of phosphorus. The
ESI SBR maintains a higher oxygen utilisation rate (OUR) from carbon stored within the bacteria, than
would be achieved from carbon substrate attained from the raw sewage. In addition, stored carbon acts as a surety
that P release will be maintained during periods of low influent bioavailable carbon.
Decanters
Additional to SBR process design and construction, ESI also designs, fabricates, installs and
commissions effluent decanters as a specialised equipment item in the wastewater industry.
ESI's stainless steel decanters are widely recognised as an excellent and reliable device and
are sometimes directly specified for incorporation in intermittent aeration plants of differing
process designs.
The reference list of supplied and installed decanters now exceeds 70 units. A further 43 units
are presently in the fabrication stage.

From: Teresa Rodriguez?, -
Date: October 1, 2002
Subject: Town of Highlands EA
The Town of Highlands submitted an Environmental Assessment for the
expansion of the Wastewater Treatment Plant from 0.5 MGD to 1.5 MGD. We
commend the Town for initiating public participation early in the process by
holding a public meeting to explain the proposed expansion. Thr► following
comments are offered regarding the Environmental Assessment document: .
♦ Growth rates of 1.79 and 3.93 for the residential and seasonal population
were used for the flow estimate. Provide the source or reference for the
growth rates used in the flow projections for both the permanent residents
and the seasonal residents.
• The areas to be annexed include existing developments. Describe the
methods of wastewater disposal for the existing developments and any
existing discharge permits. Have these developments given the town any
letter of intent to connect? Please provide a discussion of the level of
commitments from the areas to be annexed.
• The town will extend sewer service to areas served by on -site treatment
systems. Describe the operational conditions or known problems (if any)
of the existing on -site treatment systems.
• Evaluate the alternative of reusing wastewater in existing or proposed golf
courses as part of the Engineering Alternatives Analysis.

RE: Town of Highlands NPDES Permit Application
WKD #00774.40.00
Dear Richard:
The recent effluent testing performed by Pace Laboratories for the NPDES
permit application did not include testing of multiple species for the toxicity
tests. The application is a new EPA form and clearly states that at least two
species should be used in the testing. This application was mailed to Pace
before samples were taken, so they should have been aware of this. I discussed
this with Teresa Rodriquez at the Division of Water Quality, who is working on
the permitting for the Town of Highlands. She said Highlands will have to
provide an additional test performed with another species other than
Ceriodaphnia to satisfy the toxicity test requirements. It appears that Pace
performed the tests as they would for the old application. Ms. Rodriquez stated
that other labs not familiar with the new EPA form have missed this requirement
as well.
Another issue is that the new EPA form requires that testing be done on a
quarterly basis or yearly over a 4 year period. Pace performed all of it's testing
within the span of a couple weeks. This was necessary to meet the 1 80 day
requirement. Ms. Rodriquez stated that this will not be a problem due to the
fact that the Division of Water Quality is phasing in this requirement and permit
applications that are currently in the review process will not be affected.
Pace also did not perform some of the testing required for the application.
These tests include: Amonia, Chlorine (Total Rididual, TRC), Phosphorus,
B.O.D., Fecal Coliform and Total Suspended Solids (TSS). Ms. Rodriquez stated
that we could use data from treatment plant DMR sheets for the missed
information.
In, conclusion, it appears the only additional testing required will be to provide
one additional toxicity test using another species other than Ceriodaphnia. You

i
may wish to consider requesting Pace Laboratories make some concession to
the Town for missing the toxicity test.
If you have any questions, or require additional information, do not hesitate to
call.
Very truly yours,

Return #2167
Dear Mr. Betz:
The NPDES Unit received your application for an expansion at the Town of Highlands WWTP. This
package was previously submitted and returned by the Division because it was submitted without a Finding
of No Significant Impact (FONSI) and speculative limits. The speculative limits have been completed and are
expected to be issued by mid July.
As it was previously explained, the Division can not accept an expansion request before the State
Clearinghouse reviews the Environmental Assessment and issues a FONSI. The Environmental Assessment
(EA) for the Town of Highlands has not been received for review by the Division as of June 26, 2002. The
process of reviewing the EA and issuing the FONSI has not begun yet, so it is difficult to predict how long it
will take since it depends greatly on the magnitude of the project, the public interest and the impact of the
project. In average, an EA review can take 5 to 6 months if there are no significant comments. For this
reason, the Engineering Alternative Analysis must be returned.
The application submitted will be accepted as the renewal application. The Engineering Alternative Analysis
is hereby returned. Once the FONSI is issued, the expansion request can be resubmitted. At this time a fee
of $400.00 will apply.
If you have any questions concerning this request, please call me at [phone], extension 595.

Teresa Rodriguez

Memorandum
11 March 2002
To: Joe Corporon
From: Andrea Leslie, Watershed Assessment and Restoration Project
cc: Callie Dobson, Little Tennessee River Basin Planner
Subject: 7Q10 in the Upper Cullasaja River
There has been much public concern about the potential water quality impacts of Highlands'
wastewater treatment plant, which has been on the Cullasaja River since 1994. The Division
of Water Quality used equations and assumptions developed by USGS (Giese and Mason,
1991) to estimate 7Q10 flows to permit this wastewater treatment plant. Highlands is
currently preparing to expand their wastewater treatment plant. When this permit request is
processed through the Division of Water Quality, it will be important to use a 7Q10 that
reflects the hydrology and land use of the Highlands Plateau.
I understand that the 7Q10 estimations from the USGS document are intended to
approximate low flows in non -urban and unimpounded streams. The Cullasaja River and its
tributaries are dammed numerous times above Highlands' wastewater treatment plant, and
Highlands is a sprawling developed area. Evaporation from impoundments, withdrawals of
water by numerous golf courses, and impervious surface all reduce the amount of baseflow
in the Cullasaja River. It is important that the Division of Water Quality factors these
components into its 7Q10 estimation for the Cullasaja River.

Hi Joe,
Attached is a memo for the Highlands' WWTP file. When the new permit
for the expanded WWTP is considered, I feel it is important to
re-examine the 7Q10. There are a number of things that likely lower
baseflows in the Highlands area, including impervious surface, multiple
impoundments on the Cullasaja River mainstem and its tributaries, and
withdrawals of surface water for golf course watering. Using the USGS
set of assumptions and equations to calculate the 7Q10 is too simple and
likely overestimates the 7Q10 flow. Please call me if you have any
questions.
Thank you,
Andrea

Joe,
Thanks for responding. Yes, there is controversy and history here. However, the
Highlands WWTP has a permit currently and it seems like that permit has to be based
on
some numbers. Couldn't we just tell them what the current permit is based on and
then
qualify that by saying that "more study" is being done to determine if this is
appropriate and things can change in the next permit cycle, etc.? We are stirring
the
pot by what they see as us giving them the "run-around."

Highlands WWTP
Macon County
Return # 2162
In accordance with Division policy, we must hereby return the attached permit application received on
May 6, 2002. After a preliminary review by the NPDES staff, the Division has determined that the application
package lacks the following items:
• No speculative limits. Mike Myers of the NPDES Unit (919 733-5083, extension 508) is currently
developing speculative discharge limits for your facility. Until speculative limits are issued, the Unit
cannot determine the adequacy of the application. Rather than hold the application until the
speculative limits are issued and then (potentially) return it, the Division is returning the package now.
You can quickly address any changes that may be required by the speculative limits upon your receipt
of them. This will simplify the application process once the speculative limits are promulgated.
• State Environmental Policy Act (SEPA) documentation. This application was submitted
without a SEPA Environmental Assessment (EA) or Environmental Impact Statement (EIS). If you
have already submitted an EA or EIS to the State Clearinghouse, you must receive a Finding of No
Significant Impact (FONSI) before an NPDES permit application can be accepted by the Division.
SEPA requirements apply to your facility because it meets at least one of the following criteria:
> Project will use public money and/or public land
➢ Project requires an action by the State
> Project includes new flow > 0.5 MGD or exceeding 33% of the summer 7Q10 flow of the receiving
stream, or includes a flow expansion > 0.5 MGD.
Contact Todd Kennedy (919 733-5083, extension 555) or Milt Rhodes (919 733-5083, extension 366) for
guidance on completion and submission of your SEPA documentation. Once your SEPA documentation has
been approved by the State Clearinghouse, you may re -submit your application package and fee with the
FONSI.

RE: Town of Highlands NPDES Permit Application
WKD #00774.40
Dear Mr. Goodrich:
Enclosed are three copies of the NPDES Form 2A application submitted for the
Town of Highlands wastewater treatment facility expansion from 0.5 MGD to 1.5
MGD. Also enclosed is a check in the amount of $400 to pay the applicable
permit application fee and three copies of the Preliminary Engineering Report.
Three copies of the Environmental Assessment will be submitted in two weeks.
Although sampling has been completed and most of the analytical work has
been received from the laboratory a few parameters are not available from the
laboratory as of this date. We do not want to delay the submittal, therefore we
are submitting the application without this data. A submittal of all effluent data
will follow this submittal in approximately two weeks.
If you have any questions, or require additional information, do not hesitate to
call.
Sincerely,
W. K. Dickson & Company, Inc.

POTWs meeting one or more of the following criteria must provide the results of whole effluent toxicity tests for acute or chronic toxicity for each of the
facility s discharge points: 1) POTWs with a design flow rate greater than or equal to 1.0 mgd; 2) POTWs with a pretreatment program (or those that are
required to have one under 40 CFR Part 403); or 3) POTWs required by the permitting authority to submit data for these parameters.
? At a minimum, these results must include quarterly testing for a 12-month period within the past 1 year using multiple species (minimum of two
species), or the results from four tests performed at least annually in the four and one-half years prior to the application, provided the results
show no appreciable toxicity, and testing for acute and/or chronic toxicity, depending on the range of receiving water dilution. Do not include
information on combined sewer overflows in this section. AU information reported must be based on data collected through analysis conducted
using 40 CFR Part 136 methods. In addition. this data must comply with QA/QC requirements of 40 CFR Part 136 and other appropriate QA/QC
requirements for standard methods for analytes not addressed by 40 CFR Part 136.
? In addition, submit the results of any other whole effluent toxicity tests from the past four and one-half years. If a whole effluent toxicity test
conducted during the past four and one-half years revealed toxicity, provide any information on the cause of the toxicity or any results of a
toxicity reduction evaluation, if one was conducted.
? If you have already submitted any of the information requested in Part E, you need not submit it again. Rather, provide the information
requested in question E.4 for previously submitted information. If EPA methods were not used, report the reasons for using alternate methods.
If test summaries are available that contain ail of the information requested below, they may be submitted in place of Part E.
If no biomonitoring data is required, do not complete Part E. Refer to the Application Overview for directions on which other sections of the form to

Dear Mayor Trott:
Enclosed is a special condition that is to be added to the Highlands WWTP discharge
permit that was issued on March 3, 1999. This condition outlines requirements of the wastewater
management alternatives analysis that must be followed prior to the Town's request for an
increase in design flow. These requirements were agreed upon during a meeting between the
Town, State and EPA on February 9, 1998 and were outlined in a March 16, 1998 letter from the
Division to the EPA.
Please find enclosed the section of the permit referenced in the preceding paragraph and
add this new section to the permit. All other terms and conditions contained in the original
permit remain unchanged and in full effect. These permit modifications are issued pursuant to
the requirements of North Carolina General Statutes 143-215.1 and the Memorandum of
Agreement between North Carolina and the U.S. Environmental Protection Agency.
We apologize if this modification has caused any inconvenience. If you have any
questions, please contact Paul Clark at [phone], ext. 580.

SUPPLEMENT TO EFFLUENT LIMITATIONS
AND MONITORING REQUIREMENTS
SPECIAL CONDITION
A(3). WASTEWATER MANAGEMENT ALTERNATIVES ANALYSIS REQUIREMENTS
Prior to the Town's request for an increase in design flow (permit modification or reissuance), the Town
must submit a description of the proposed expansion to the Division of Water Quality for evaluation under the
State Environmental Policy Act (SEPA). If the proposed project requires preparation of an environmental
document under the provisions of SEPA (NCAC TO1 25 .0108 and T15A: O 1 C .0500), the document must include,
in addition to meeting all the provisions of SEPA, a thorough consideration of wastewater management options
available to the Town. Should the State determine that the development of a document under SEPA would not be
required, as a part of the documentation necessary to apply for a flow increase under Division rules (NCAC T15A
02H .0100), the Town must submit an evaluation of wastewater management alternatives. Thus, whether or not a
SEPA document is required, the Town shall submit an analysis of wastewater management options. When
preparing this analysis, the permittee should consult Guidance for the Evaluation of Wastewater Disposal
Alternatives (prepared by the NPDES Unit and attached to this letter). Some of the requirements contained within
the Guidance document are mentioned below for purposes of clarification and emphasis and include the following:
- Justification and demonstration of the need for the proposed flow increase must be provided. Flow reduction
(i.e., inflow/infiltration analyses) and water conservation measures must be investigated. The analysis should
include flow reduction projections.
- No Action Option
- Accommodation of expected growth in wastewater management needs by private, on -site treatment disposal
systems.
- Land application of the additional wastewater flow (greater than the current treatment plant design) on public
(Forest Service) or private land (purchased, leased or use of property obtained by agreement).
- Expansion of the existing treatment system along with the construction of a land application system for all or
a portion of the treated wastewater during all or a portion of the application year (requiring discharge and land
application permits). This alternative should consider the use of public and private property.
- Expansion of the existing treatment system with the development of a treated wastewater reuse program
utilizing public and/or private property.
- Expansion of the existing treatment system with discharge of the wastewater to the Cullasaja River (existing
discharge point).
In developing these alternatives and any others required as part of SEPA compliance (if applicable), the Town
must include the following considerations:
- The practical, legal, administrative, and technical aspects of securing: (1) permission to use US Forest
Service property for application of wastewater and (2) cooperation of private land owners in allowing the
application or reuse of treated wastewater on land managed for recreational purposes, i.e., golf courses.
- The development of realistic cost projections (using Present Value of Costs Analysis) for each alternative
considered.
- The impact of agency action to require higher levels of treatment on any expansion of the existing discharge
volume.
