Class 3 Facility
Dear Mr. Chamblee:
Donald R. van der Vaart
Secretary
Division pers el have reviewed and approved your application for renewal of the subject permit.
Accordingly, e are forwarding the attached NPDES 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 permik't contains the following changes from your previous permit:
• In resp�nse to your comments on the draft permit the description of the wastewater
treatm nt system was modified to include reaeration as one of the components.
• The pe -mit includes an intermediate flow tier for 2.5 MGD. The flow trigger to go to the
next ti r will be when the calendar year average flow exceeds 90% of permitted flow. Special
Condi on A. (6) includes the requirements to notify the Division when the flow trigger is
met.
• Monitoring for total residual chlorine was eliminated from the permit since UV is used as the
disinfection method.
• Quartefly monitoring for total zinc was added to the effluent monitoring requirements for all
flow phases. Total zinc was detected during the effluent pollutant scan at concentrations
greater than the water quality action level.

• The requirement to perform effluent pollutant scans was modified from annual to three
times during your permit cycle. See Special Condition A.(5). This condition also includes
requirements for toxicity testing with alternate species.
• A special condition was added to the draft permit to address the Environmental Protection
Agency's (EPA's) pending requirement for you to provide electronically -submitted
Discharge Monitoring Reports (eDMRs). The Division intends to fully implement the
eDMR program as soon as practicable. See Condition A.(7.) in permit. For information on
eDMR, registering for eDMR and obtaining an eDMR user account, please visit the
following web page:
http: / /portal.ncdenr. org/web /wq/admin/bog/ipu/edmr.
For information on EPA's proposed NPDES Electronic Reporting Rule, please visit the
following web site:
http: / /www2. epa.gov/ compliance /prop o s ed-npdes-electronic-reporting-rule.
Please be aware that future initiatives in water quality permitting will include the development of
statewide nutrient criteria for lakes and reservoirs by 2023. Nutrient limits are likely to be included in
NPDES permits at that time or upon permit expansions above current permitted flows.
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 nottransferable 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
Resources or any other Federal, State, or Local governmental permits that may be required.
If you have any questions concerning this permit, please contact Teresa Rodriguez at telephone
number [phone] or at email [e-mail].

Calendar Quarter
One of the following distinct periods: January through March, April through June, July through September, and
October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 mL in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time interval
between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or automatically. Composite
samples may be obtained by the following methods:
(1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24 hour period
of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection, or
Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period with
the time intervals between samples determined by a preset number of gallons passing the sampling point. Flow
measurement between sample intervals shall be determined by use of a flow recorder and totalizer, and the
preset gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at
the treatment system, or

(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at a
constant time interval. Use of this method requires prior approval by the Director. This method may only be
used in situations where effluent flow rates vary less than 15 percent. The following restrictions also apply:
➢ Influent and effluent grab samples shall be of equal size and of no less than 100 milliliters
> Influent samples shall not be collected more than once per hour.
> Permittees with wastewater treatment systems whose detention time < 24 hours shall collect effluent grab
samples at intervals of no greater than 20 minutes apart during any 24-hour period.

Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance
activities on the flow device.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as
the total mass of the pollutant discharged over the day. For pollutants expressed in other units of measurement, the
"daily discharge" is calculated as the average measurement of the pollutant over the day. (40 CFR 122.2; see also
"Composite Sample," above.)
Daily Maximum
The highest "daily discharge" during the calendar month.
Daily Sampling
Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the

PART IV
SPECIAL CONDITIONS FOR MUNICIPAL FACILITIES
Section A. Definitions
In addition to the definitions in Part II of this permit, the following definitions apply to municipal facilities:
Indirect Discharge or Industrial User
Any non -domestic source that discharges wastewater containing pollutants into a POTW regulated under section
307(b), (c) or (d) of the CWA. [40 CFR 403.3 (i) and (j) and 15A NCAC 02H .0903(b)(11)]
Interference
Inhibition or disruption of the POTW treatment processes; operations; or its sludge process, use, or disposal which
causes or contributes to a violation of any requirement of the Permittee's (or any satellite POTW's if different from the
Permittee) NPDES, collection system, or non -discharge permit or prevents sewage sludge use or disposal in
compliance with specified applicable State and Federal statutes, regulations, or permits. [15A NCAC 02H
.0903(b)(14)]
Pass Through
A discharge which exits the POTW into waters of the State in quantities or concentrations which, alone or with
discharges from other sources, causes a violation, including an increase in the magnitude or duration of a violation, of
the Permittee's (or any satellite POTW's, if different from the Permittee) NPDES, collection system, or non -discharge
permit. [15A NCAC 02H .0903(b)(23)]
Publicly Owned Treatment Works (POTW)
A treatment works as defined by Section 212 of the CWA, which is owned by a State or local government organization.
This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature. It also includes the collection system, as defined in 15A NCAC 2T
.0402, only if it conveys wastewater to a POTW treatment plant. The term also means the local government
organization, or municipality, as defined in section 502(4) of the CWA, which has jurisdiction over indirect discharges
to and the discharges from such a treatment works. In this context, the organization may be the owner of the POTW
treatment plant or the owner of the collection system into which an indirect discharger discharges. This second type of
POTW may be referred to as a "satellite POTW organization." [15A NCAC 02H .0903(b)(26)]
"Significant Industrial User" or "SIU"
An Industrial User that discharges wastewater into a publicly owned treatment works and that [15A NCAC 02H
.0903(b)(33)]:
1. Discharges an average of 25,000 gallons per day or more of process wastewater to the POTW (excluding sanitary,
noncontact cooling and boiler blowdown wastewaters); or
2. Contributes process wastewater which makes up five percent or more of the NPDES or non -discharge permitted
flow limit or organic capacity of the POTW treatment plant. In this context, organic capacity refers to BOD, TSS
and ammonia; or
3. Is subject to categorical standards under 40 CFR Part 403.6 and 40 CFR Parts 405-471; or
4. Is designated as such by the Permittee on the basis that the Industrial User has a reasonable potential for adversely
affecting the POTW's operation or for violating any pretreatment standard or requirement, or the POTW's effluent
limitations and conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options;
5. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraphs 1 or 2 of this definition above has no reasonable potential for adversely affecting the
POTW's operation or for violating any pretreatment standard or requirement, the POTW's effluent limitations and
conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options, and thus is not a
Significant Industrial User (SIU); or
6. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraph 3 of this definition above meets the requirements of 40 CFR Part 403.3(v)(2) and thus is a
non -significant categorical Industrial User.

wastestreams with a closed cup flashpoint of less than 140 degrees Fahrenheit or 60 degrees Centigrade
using the test methods specified in 40 CFR 261.21;
(2) Pollutants which cause corrosive structural damage to the POTW, but in no case discharges with pH lower
than 5.0, unless the works is specifically designed to accommodate such discharges;
Solid or viscous pollutants in amounts which cause obstruction to the flow in the POTW resulting in
Interference;
(4) Any pollutant, including oxygen demanding pollutants (BOD, etc.) released in a Discharge at a flow rate
and/or pollutant concentration which will cause Interference with the POTW;
Heat in amounts which will inhibit biological activity in the POTW resulting in Interference, but in no
case heat in such quantities that the temperature at the POTW Treatment Plant exceeds 40°C (104°F)
unless the Division, upon request of the POTW, approves alternate temperature limits;
(6) Petroleum oil, non -biodegradable cutting oil, or products of mineral oil origin in amounts that will cause
Interference or Pass Through;
Pollutants which result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that
may cause acute worker health and safety problems; or
Any trucked or hauled pollutants, except at discharge points designated by the POTW.
All POTWs must provide adequate notice to the Director of the following [40 CFR 122.42(b)]:
1. Any new introduction of pollutants into the POTW from an indirect discharger, regardless of the means of
transport, which would be subject to section 301 or 306 of CWA if it were directly discharging those pollutants;
and
2. Any substantial change in the volume or character of pollutants being introduced by an indirect discharger as
influent to that POTW at the time of issuance of the permit.
3. For purposes of this paragraph, adequate notice shall include information on (1) the quality and quantity of effluent
introduced into the POTW, and (2) any anticipated impact that may result from the change of the quantity or
quality of effluent to be discharged from the POTW.
(3)
(5)
(7)
(8)
c. The Permittee shall investigate the source of all discharges into the POTW, including slug loads and other
unusual discharges, which have the potential to adversely impact the Permittee's Pretreatment Program and/or
the operation of the POTW.
The Permittee shall report such discharges into the POTW to the Director or the appropriate Regional Office.
Any information shall be provided orally within 24 hours from the time the Permittee became aware of the
circumstances. A written submission shall also be provided within 5 days of the time the Permittee becomes
aware of the circumstances. The written submission shall contain a description of the discharge; the
investigation into possible sources; the period of the discharge, including exact dates and times; if the
discharge has not ceased, the anticipated time it is expected to continue; and steps taken or planned to reduce,
eliminate, and prevent reoccurrence of the noncompliance,

SUMMARY:
The Killian Creek WWTP started operations of the 1.68 MGD WWTP in 2010. The existing
WWTP conrists of bar screen, grit separator, dual sequencing batch reactors, post equalization
basins, two effluent filters, UV disinfection, effluent reaeration, aerobic digester, and sludge
holding basins. The permit has tiered limits of 1.68 MGD and 3.38 MGD. The County plans to
construct the second phase to bring the capacity to 3.3JMGD during 2015-2016. The County
requested an intermediate tier of 2.5 MGD once the plant is upgraded to 3.35 MGD.
RECEIVING STREAM
The facility, discharges into Killian Creek, a class C waterbody in the Catawba River Basin, HUC
03050101 ICreek is listed as impaired in the 2014 303(d) list for fair fish community.

SUMMARY OF PROPOSED CHANGES
1. The supjlement to cover sheet was updated to include the description of the WWTP.
2. The permit includes additional page with effluent and monitoring requirements for the 2.5 MGD
flow tier! Expansion to 3.35 MGD will be completed next year but the tributary flows to the
plant are not expected to be above the 2.25 MGD for some time. Flow trigger for moving to the .
next tier ill be at 90% of the permitted flow since construction of the WWTP at the ultimate
capacity of 3.35 MGD will be finalized before they will move the next flow tier.
3. Quarter monitoring for total zinc was added to the effluent monitoring requirements.
4. Monitoring for total residual chlorine was eliminated from the permit as the WWTP utilizes UV
for disinfection.
5. The permit includes a special condition with new requirements for electronic reporting of DMRs.

RE: Killian Creek

Bob- we will consider the request during permit renewal. I think you are talking about transition language to go from
1.68 MGD to 3.35 MGR effluent sheets. There are various triggers that we use (e.g., receipt of Engineer Certificate,
annual flow exceeds 80% of Permitted Flow, etc). There is not much of a change in permit limits between the 2 sheets
(BOD/TSS are secondary limits at 30/45 mg/I, while ammonia becomes slightly more stringent). My guess would be the
concern of an ORC Grade 4 requirement at >2.5 MGD permitted flow, plus more frequent monitoring for a Grade 4
facility.

We are beginning work on the Killian Creek WWTP NPDES Permit NC0088722 Renewal application. The current permit
has 2 tiers based upon plant capacity of 1.68 mgd and 3.35 mgd. To increase the permitted capacity to 3.35 mgd,
requires the addition of equipment items omitted during the original construction (Le. aeration diffuser assemblies,
blowers, an effluent filter, a second UV system and expansion of the dewatering system). These additions generally only
involve the addition o equipment and related electrical supply with very minor related construction. The related
permits and construction will likely be completed in 2015 or 2016.
As the permit is renewed, would it be possible to get a new permit based on tiered flows for annual average daily flows
for below 1.68 and 1.68 to 3.35 mgd. We would like to avoid moving immediately to the new effluent limitation as soon
as the plant is permitted for 3.35 mgd when flows may actually still be well below the 1.68 mgd.
Thanks for your assistance.

Bob- Nutrient limits will not be imposed during the next permit renewal in 2015. However, it is likely that the plant will
receive nutrient limits in the next decade, either through Lake Wylie considerations or a recent commitment to EPA to
develop statewide nutrient criteria for lakes and reservoirs by 2023. Additionally, any future expansion beyond the
current permitted flow of 3.35 MGD would trigger nutrient considerations. With that in mind, it is prudent to make
allowances for upgrading to BNR in the future. Hope this helps. Let me know if any further questions.

Tom —
We are preparing to begin work on the renewal of the Lincoln County WWTP NPDES Permit NC008722 — Killian Creek
WWTP that expires on 2/28/15.
This permit includes a tiered permit for flows of 1.68 mgd and 3.35 mgd. When permitted for construction, Lincoln
County elected to omit some equipment items needed for the 3.35 mgd capacity (i.e., blowers, aeration diffusers, an
effluent filter and UV bank). Lincoln County is now planning on taking the next step to add the previously omitted
equipment to permit capacity for future growth. The plant ADF is now approaching 0.9 mgd with several major
developments in the planning stage. We anticipate the installation of the omitted equipment with minimal other
construction necessary to provide a WWTP capable of the 3.35 mgd permitted flow.

In previous discussions with DENR (Mooresville), it was suggested that plants within the Catawba basin would likely have
a nutrient standard for phosphorous on new permit. Can you advise if the new NPDES permit for Killian Creek will
include phosphorous and/or total nitrogen to permit Lincoln County to begin planning for the related modifications to
be performed as part of this next plant modification?
Are there any issues the proposed expansion creates that will need to address with the permit renewal? Obviously, we
recognize an ATC will be required for the related construction.
Thanks for any input you may provide.

Iincoln county - killian creek wwtp
For what it's worth, here are a few of my notes from today's conference call involving you, Kathy Stecker, Mike Parker
(MRO), and me. I hope they're accurate and of some use.
Bob Froneberger (WKDickson), the County's consultant, has asked whether we intend to set nutrient limits for the
Killian Creek WWTP. Hie seems open to the possibility,and theplant design will make allowances for upgrading to BNR
p g P
even if limits are not imposed now.
The WWTP itself is outside the Lake Wylie TMDL study area, but the creek joins the Catawba within the study area (that
is, below Mountain Island Dam). We (NPDES) probably should have established nutrient limits for the expansion to 3.35
MGD. We missed the chance, and neither the 2004 spec limits nor the current permit include nutrient limits. None of us
today felt we have a compelling reason to add them now, as the County prepares to begin the expansion project.
The response to Bob F s question should/ could include the following points:
Given the scope o the Lake Wylie TMDL, we will be obliged to set nutrient limits for this discharge at the first
opportunity — expnsion above 3.35 MGD, other major plant mods, etc.
In the NCDP just Treed upon with EPA R4, DWR committed to developing statewide nutrient criteria for lakes &
reservoirs by 2023. So it is possible that the plant could receive nutrient limits separate from the TMDL.
hus, it appears liltely that this plant will receive nutrient li
or so.
The move to BNR equires a major leap in treatment technology and operations expertise. The plant must first be
upgraded to tertiary treatment (5 & 1 for BOD and NH3-N, or thereabouts) to nitrify ammonia to nitrates; then to
BNR to remove the nitrates. These upgrades require a shift toward high-tech systems and operation, and they come
with a big learning curve.
If we accept that utrient limits are likely in the next 10 years, it could be in the County's interest to begin building
toward those requirements now, at a manageable pace, rather than having to make the transition all at once.
The addition of B R offers some cost savings (reduced aeration and sludge generation) compared to tertiary
treatment withou BNR.

Lincoln County/Lk Wylie
Rob- just a few more thqughts on the Lincoln County/Forney Creek/Killian Creek question:
• I'd push our standard NPDES goal to reduce dischargers, so if Lincoln County can shunt Forney flow to Regional
Killian WWTP, all the better.
• If their question is whether they should retain permit for Forney WWTP, I'd ask what the concern is- do they
want to retain flow just in case (or I'm wondering if they think there is a nutrient allocation to transfer or sell)?
• Nutrients- based on Lk Wylie Mgt Strategy, the newer Regional Killian WWTP probably should have received
nutrient limits. Whey have no allocation from the TMDL/Point Source side, so we will have to take it from the
Non -Point allocation (with EPA approval).
• If you want to do a conference call with us and consultant, that would be fine, as its difficult at this point to

Killian is a new plant is located a couple miles closer to the confluence with the Catawba.
They do not have TN or TP limits in either permit. Killian is 1.68 MGD (expandable to 3.35 mgd) and Forney is .975 mgd

Lake Wylie has a nutrient TMDL. How much closer to the lake/Catawba River will the new discharge be (is it new, or just
a new plant?)?
If they won't be increasing their overall nutrient loading, it should be OK. Do they have TP and TN limits in their current
permit(s)?

Do you have any information that may assist Lincoln County in determining if they should consider temporarily closing or

With regard to the permit renewal, it is requested that the following permit modification be
considered:
• The current permit includes effluent limitations for effluent Total Residual Chlorine (TRC).
Since thi facility utilizes UV disinfection, it is requested this parameter be omitted.
• The curr nt permit includes two (2) tiered effluent monitoring requirements based upon the
"permitted capacity" of 1.68 and 3.35 MGD. It is requested the new permit effluent
limitatio s be have three (3) tiers conditioned upon a twelve month running average flow
with tier d levels up to 1.68 mgd,1.68 to 2.5 mg_d1 and 2.5 mgd to 3_35 mgd. The tiered flow
based of uent limits are requested to avoid an increased monitoring frequency and more
restrictiv effluent limits when the plant permitted capacity is increased to 3.35 mgd before
the actu 1 plant flow increases.
Should you need any additional information or have questions related to this permit renewal
application, please contact our engineer, Charles R. Froneberger, P.E. at 704-334-5348 or email

Inflow is estimated .. 140 qpd/capita and infiltration estimated to be negligible. See Additional Information on page 22 /23.
Briefly explain any steps underway or planned to minimize inflow and infiltration.
Lincoln County has an ongoing program to routinely clean and inspect, both visually and by TV, the gravity collection
system. The low pressure sewer mains operate under pressure, so I/1 is not an issue.
B.2. Topographic Map. Attach to this application a topographic map of the area extending at least one mile beyond facility property boundaries. This
map must show the outline of the facility and the following information. (You may submit more than one map if one map does not show the entire

SUPPLEMENTAL APPLICATION INFORMATION
PART E. TOXICITY TESTING DATA
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. All 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 analyses 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 all of the information requested below, they may be submitted in place of Part E.

ADDITIONAL INFORMATION
KILLIAN CREEK WVVfP NPDES FORM 2A APPLICATION
NPDES Number: NC0088722
The following information is submitted as additional information to the NPDES Permit Application for the Killian
Creek V VVfP:
Item # A.4 Collection System Information
The Killian Creek VWVTP currently serves an area primarily within the Catawba Springs Township within the
Forney Creek and Killian Creek drainage basins. Based upon US Census information, the total 2014
population of this area is estimated to be approximately 18,225 capita. It is estimated that approximately 70%
of this population or approximately 12,757 capita is currently served by sewer.
Future proposed sewer expansions in the Anderson Creek and Leepers Creek drainage basins combined with
population growth within the Catawba Springs Township projects a potential sewer service population
approaching 32,000 capita by the year 2034.
Item # A.11 Description of Treatment
The wastewater treatment process consists of the following treatment units:
• Influent headworks including mechanically cleaned screen, by-pass manually cleaned screen and
vortex grit collection system.
• Sequencing Batch Reactors (SBR's) — 2 Basins
• Post Equalization Basin
• Effluent Tertiary Disk Filters
• Ultraviolet (UV) Disinfection
• Effluent V-notch Weir
• Reaeration Channel
• Aerobic Digestion — Primary and Secondary
• Sludge Holding Tank
• Sludge Dewatering Rotary Filter Press
Item B.1 Inflow and Infiltration
Computation of inflow and infiltration at the Killian Creek WWTP is impacted by the sequencing batch reactor
(SBR) process and a post SBR equalization basin that can have an impact on effluent flow patterns.
Additionally, Duke Energy has a periodic discharge of process water not included in the potable water supply
that can impact the daily flow pattern.
Calculations of inflow utilizing a four (4) day dry period followed by a 1-inch or greater rainfall event indicate an
inflow for the collection system of 140 gpd/capita.
Calculations of infiltration utilizing wastewater flows from the two (2) wettest months compared to water use
records yields an estimated infiltration of <-277 >gpd/inch diameter mile; therefore, the infiltration was
considered to be negligible. This is likely associated with the large percentage of low pressure sewers within
the system in developed areas around Lake Norman.
NPDES FORM 2A Additional Information
Page 22 of 23

Item B.5 Scheduled Improvements
the Killian Creek VVWTP was initially designed for a capacity of 3.35 mgd. To reduce initial costs, the
installation of redundant equipment items needed for the 3.35 mgd capacity was delayed and the initial plant
operation was permitted for 1.68 mgd. Lincoln County's recent closure of the Forney Creek WVVTP (NPDES
Permit #NC0074012) and the diversion of flow from this facility to the Killian Creek VVWTP plus future planned
local area developme t are expected increase the future flow to the Killian Creek WWTP that will approach the
current permitted cap city of 1.68 mgd. To accommodate the additional flow, Lincoln County proposes to
proceed with improve ents to accommodate a permitted capacity expansion to 3.35 mgd. These
improvements are pr posed to include the following plant equipment additions with a completion date
projected for Septem er 2016:
•Ten (10) aera ion diffuser assemblies within the sequencing batch reactor basins (SBR).
•One (1) SBR eration blower.
•Two (2) post BR equalization pumps.
•One (1) efflue t filter unit.
•One (1) dual ank ultraviolet disinfection unit in existing effluent channel.
•One (1) aerob c digestion blower.
•One (1) rotary lobe sludge pump.
•One (1) rotary filter press.
The proposed equipml ent additions are to allow an increase in the plant capacity to 3.35 mgd and are not
associated with any ir'nposed regulatory compliance or implementation schedules. These equipment additions
and several other pla t modifications currently under consideration are to be accomplished in accordance with
the NCDER "Authori ation to Construct" permitting program.

3. Post Equalization Basin
SBR effluent removed through the decanters is transferred into a post equalization basin for
storage following the short duration, high flow decanting operation. Variable speed pumps
then transfer the secondary treated effluent to the filtration system to provide a relative
constant flow rate through the downstream filters and disinfection system. One pump is
designed to handle the average daily flow with the remaining two pumps provided for peak
flow events and backup.
4. Effluent Filters
Effluent filtration is provided by two (2) cloth disk filter units containing twelve (12) filter
disks per unit. Each filter has a maximum hydraulic capacity of 4.2 MGD and is designed to
produce an effluent containing less than 5 mg/1 suspended solids. Filters backwash is
initiated on head loss through the filter by pulling filtered water back through the filter media
with the backwash sent to the plant drain for return to the SBR system.
5. Ultraviolet Disinfection
The ultraviolet disinfection system provides for reduction of fecal coliform utilizing •
ultraviolet light. The ultraviolet system includes two banks with 3 modules of 30 lamps
