MOORESV ILLE IRMIONAt_ OFFICE
This is to inform you that a review of your toxicity self -monitoring report forms for October 2018 indicates a
violation of the toxicity limitation specified in your NPDES Permit.
You should take whatever remedial actions are necessary to eliminate the conditions causing the effluent toxicity
violation(s). Your efforts may include conducting a Toxicity Reduction Evaluation (TRE), a site -specific study
designed to identify the causative agents of effluent toxicity, isolate the sources of toxicity, evaluate the
effectiveness of toxicity control options, and confirm reductions in effluent toxicity. Please be aware that North
Carolina General Statutes provide for assessment of civil penalties for violations of NPDES permit limitations and
requirements.
The reverse side of this Notice contains important information concerning your Whole Effluent Toxicity Monitoring
and Reporting Requirements. Please note appropriate mailing addresses for submitting your Discharge Monitoring
Reports (DMRs) and Aquatic Toxicity (AT) Test Forms. We encourage you to review this information; if it would be
helpful to discuss this situation or possible solutions to resolve effluent toxicity noncompliance, please contact Ms.
Cindy Moore at [phone] or Ms. Susan Meadows at (919) 743- 8439.

WHOLE EFFLUENT TOXICITY MONITORING AND REPORTING INFORMATION
➢ The following items are provided in an effort to assist you with identifying critical and sometimes overlooked toxicity testing and reporting
information. Please take time to review this information. The items below do not address or include all the toxicity testing and
reporting requirements contained in Your NPDES permit. If you should have any questions about your toxicity testing requirement,
please contact Mr. John Giorgino with the Aquatic Toxicology Branch at [phone] or another Branch representative at the same
number.
➢ The oermittee is responsible for ensuring that toxicity testing is conducted according to the permit requirement and that toxicity report
forms are appropriately filed.
D The reporting of whole effluent toxicity testing data is a dual requirement. All toxicity test results must be entered (with the appropriate
parameter code) on your monthly Discharge Monitoring Report which is submitted to:
North Carolina Division of Water Resources
Central Files
1617 Mail Service Center
Raleigh, NC 27699-1617
IN ADDITION
Toxicity test data (original "AT" form) must be submitted to the following address:
North Carolina Division of Water Resources
Water Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
or
Email to: [e-mail]
➢ Toxicity test results shall be filed with the Water Sciences Section no later than 30 days after the end of the reporting period (eg,
January test result is due by the end of February).
➢ Toxicity test condition language contained in your NPDES permit may require use of multiple concentration toxicity testing upon failure of
any single quarterly toxicity test. If the initial pass/fail test fails or if the chronic value is lower than the permit limit, then at least two
multiple concentration toxicity tests (one per month) will be conducted over the following two months. As many analyses as can be
completed will be accepted. If your NPDES permit does not require use of multiple concentration toxicity testing upon failure of any
single quarterly test, you may choose to conduct either single concentration toxicity testing or multiple concentration toxicity testing per
the Division's WET enforcement initiatives effective July 1,1999. Follow-up multiple concentration toxicity testing will influence the
Division's enforcement response.
➢ Toxicity testing months are specked by the NPDES Permit, except for NPDES Permits which contain episodic toxicity monitoring
requirements leg, if the testing months specified in your NPDES permit are March, June, September, and December, then toxicity testing
must be conducted during these months).
➢ If your NPDES Permit specifies episodic monitoring and your facility does not have a discharge from January 1-June 30, then you must
provide written notification to the Water Sciences Section by June 30 that a discharge did not occur during the first six months of the
calendar year.
➢ If you receive notification from your contract laboratory that a test was invalidated, you should immediately notify the Water Sciences
Section at [phone] and provide written documentation indicating why the test was invalidated and the date when follow-up
testing will occur.
➢ If your facility is required to conduct toxicity testing during a month in which no discharge occurs, you should complete the information

Subject: Speculative Effluent Limits
Killian Creek WWTP
Permit No. NC0088722
Lincoln County
Catawba River Basin
This letter provides speculative effluent limits for 4.9 MGD and 6.6 MGD at the Killian Creek
WWTP. The Division received the speculative limits request in a letter dated February 20, 2017.
Please recognize that speculative limits may change based on future water quality initiatives, and
it is highly recommended that the applicant verify the speculative limits with the Divisions
NPDES Unit prior to any engineering design work.
Receiving _Stream. Killian Creek is located within the Catawba River Basin. Killian Creek has a
stream classification of C. Waters with C classification have a best usage for aquatic life
propagation and maintenance of biological integrity, wildlife, secondary recreation and
agriculture. The USGS provided flow statistics for Killian Creek on June 2, 2017. For the
discharge location the summer 7Q10 flow is 3.1 cfs, winter 7Q10 flow is 7.5 cfs, and an annual
30Q2 is 10.8 cfs. Please note these values are slightly different than previously used in the
permit. The previous permit listed the drainage area as 36 mi2. This area corresponds to the area
at the Killian Creek USGS station near Mariposa. The drainage area at the point of discharge
was verified as 46.8 mil.
Killian Creek is not currently listed as an impaired waterbody on the draft 2016 North
Carolina 303(d) Impaired Waters List.
Based upon a review of information available from the North Carolina Natural Heritage
Program Online Map Viewer, there are not any Federally Listed threatened or endangered
aquatic species identified within a 5 mile radius of the proposed discharge location.
Speculative Effluent Limits. Based on Division review of receiving stream conditions,
speculative limits for the proposed expansion to 4.9 and 6.6 MGD are presented in Table 1. A
complete evaluation of these limits and monitoring requirements for metals and other
toxicants, as well as potential instream monitoring requirements, will be addressed upon
State of ltiorlh Carolina j Enviranmental Quality ' Water Resources
1617.Mail senice Center ;Raleigh, North Carolina 'ifi 7-1617

receipt of a formal NPDES permit application. Some features of the speculative limit
development include the following:
• BOD/NH3 Limits. A level B model was developed to evaluate limits for BOD and
ammonia. The model predicted that effluent concentrations of 5 mg/1 BOD and 1 mg/1
ammonia will not cause exceedances in the dissolved oxygen instream standard for
both proposed flow scenarios.
• Total NitrqapZLoAqI Phosphorus. The Division developed a Nutrient Management
Strategy for Lake Wylie in 1995 due to eutrophic conditions in the lake. The Lake Wylie
Nutrient Management Area encompasses Lake Wylie and its tributaries including the
Catawba River and its tributaries below Mountain Island Dam. Killian Creek is a
tributary to the Catawba River within the Lake Wylie Management Area. The strategy
for expansions of existing discharges presented in the 1995 Catawba River Basin Plan
recommends the use of advanced nutrient removal technology. For expanding
facilities with permitted flows greater than 1 MGD the strategy recommends monthly
average limits of 1 mg/1 Total Phosphorus (TP) and 6 mg/1 Total Nitrogen (TN) (TN
applies April to October only).

an NPDES permit for a new or expanding discharge will be issued with these speculative
limits. Final decisions can only be made after the Division receives and evaluates a formal
permit application for the new/expanded discharge. In accordance with North Carolina
Administrative Code 15A NCAC 2H.0105(c), the most environmentally sound alternative

F7
should be selected from all reasonably cost effective options. Therefore, as a component of
all NPDES permit applications for new or expanding flow, a detailed engineering alternatives
analysis (EAA) must be prepared. The EAA must justify requested flows and provide an
analysis of potential wastewater treatment alternatives. A copy of the Division guidance for
preparing EAA documents is attached.
State Environmental Policy Act (SEPA) EA/EIS Requirements. A SEPA EA/EIS document
may be required for projects that: 1) involve $10 Million or more of state funds; or 2) will
significantly and permanently impact 10 or more acres of public lands. Please check with the
DWR SEPA coordinator (David Wainwright, 919-807-6442) as to whether your project
requires SEPA review. For projects that are subject to SEPA, the EAA requirements discussed
above will need to be folded into the SEPA document. Additionally, if subject to SEPA, the
NPDES Unit will not accept an NPDES permit application for a new/expanding discharge
until the Division has approved the SEPA document and sent a Finding of No Significant
Impact (FONSI) to the State Clearinghouse for review and comment.
Should you have any questions about these speculative limits or' NPDI~S permitting
requirements, please feel free to contact Teresa Rodriguez at [phone] or Julie Grzyb at

ATC SECTION 2 — ITEM # D
BRIEF DESCRIPTON OF PROJECT
LINCOLN COUNT — KILLIAN CREEK WWTP UPGRADE
The proposed project is an upgrade of the existing Killian Creek WWTP to facilitate an increase
in the permitted capacity from 1.68 to 3.35 mgd. The plant was originally designed for 3.35 mgd
with some equipment items needed for a capacity over 1.68 mgd delayed to avoid unnecessary
costs resulting in an initial permitted capacity of 1.68 mgd. In anticipation of continued County
growth, Lincoln County now desires to install the previously omitted equipment plus several
operational related improvements to allow an increase in the permitted capacity to 3.35 mgd.
Proposed plant modifications include the following plant additions:
1. Ten (10) retrievable aeration diffuser racks in existing Sequencing Batch Reactor (SBR)
Basins;
2. Two (2) positive displacement blowers for SBR and Aerobic Digesters;
3. Two (2) submersible pumps in Post Equalization Basin;
4. One (1) effluent disk filter;
5. One (1) ultraviolet disinfection system with two (2) banks;
6. One (1) rotary lobe sludge transfer pump;
7. One (1) rotary filter press system including existing modifications to connect new rotary
filter press to the existing inclined dewatered solids conveyor.
8. One (1) new drum thickener system including package pump station for transfer of sludge
from digesters to rotary drum thickener, polymer system, progressive cavity pump for
transfer of dewatered sludge to digester #1 or #2, precast concrete building and associated
interconnecting piping.
9. Modifications to dewatered sludge distributing conveyor to permit feeding of dewatered
solids to two dumpsters.
10. Addition of four (4) submersible mixers and associated controls at Post Equalization basin.
11. New plant effluent reuse water system including effluent supply pumps, reuse water storage
tank and foundation, package booster pump system, hypochlorite feed system, chemical
drum storage pallet, basket strainer and associated piping.
12. Electrical modifications to provide start/stop capability for Aerobic Digester #2 and Sludge
Holding Tank sludge transfer pumps at the sludge truck loading station in the Sludge
Dewatering Building.
13. Modification to truck loading station piping and hose to improve flexibility in loading
liquid sludge trucks for land application.
14. RAS piping modifications and valve additions in the Sludge Holding Tank to permit sludge
transfer of from Digester No. 2 back to Digester 1.
15. Grating modifications at effluent weir to provide better sampling access.

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 contains the following changes from your previous permit:
• In response to your comments on the draft permit the description of the wastewater
treatment system was modified to include reaeration as one of the components.
• The permit includes an intermediate flow tier for 2.5 MGD. The flow trigger to go to the
next tier will be when the calendar year average flow exceeds 90% of permitted flow. Special
Condition 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 LTV is used as the
disinfection method.
• Quarterly 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.

A. (4) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY) [15A NCAC 02B .0200 et seq.]
The permittee shall conduct quarterl chronic toxicity tests using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, or subsequent
versions.
The effluent concentration defined as treatment two in the procedure document is 52% (1.68 MGD)/ 62%
(2.5 MGD) / 68% (3.35 MGD). The testing shall be performed as a Ceriodaphnia dubia 7-day pass/fail test.
The tests will be performed during the months of January, April, July and October. These months
signify the first month of each three month toxicity testing quarter assigned to the facility. Effluent
sampling for this testing must be obtained during representative effluent discharge and shall be performed at
the NPDES permitted final effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B.
Additionally, DWR Form AT-1 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Section no later than 30 days
after the end of the reporting period for which the report is made.
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual chlorine of
the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the
waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is
required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test
form indicating the facility name, permit number, pipe number, county, and the month/year of the report
with the notation of "No Flow" in the comment area of the form. The report shall be submitted to the
Water Sciences Section at the address cited above.
Should the petmittee fail to monitor during a month in which toxicity monitoring is required, then monthly
monitoring will begin immediately. Upon submission of a valid test, this monthly test requirement will
revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division
of Water Resources indicate potential impacts to the receiving stream, this permit may be re -opened and
modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival, minimum control organism reproduction, and appropriate environmental controls, shall
constitute an invalid test and will require immediate follow-up testing to be completed no later than the last
day of the month following the month of the initial monitoring.

Raleigh, North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility
being physically located in an area where less than 10 percent of the households have broadband access,
then a temporary waiver from the NPDES electronic reporting requirements may be granted and
discharge monitoring data may be submitted on paper DMR forms (MR 1, 1. 1, 2, 3) or alternative forms
approved by the Director. Duplicate signed copies shall be submitted to the mailing address above.
Requests for temporary waivers from the NPDES electronic reporting requirements must be submitted
in writing to the Division for written approval at least sixty (60) days prior to the date the facility would
be required under this permit to begin using eDMR. Temporary waivers shall be valid for twelve (12)
months and shall thereupon expire. At such time, DMRs shall be submitted electronically to the
Division unless the permittee re -applies for and is granted a new temporary waiver by the Division.

(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
(3) 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.
➢ Permittees with wastewater treatment systems whose detention time exceeds 24 hours shall collect effluent
grab samples at least every six hours; there must be a minimum of four samples during a 24-hour sampling
period.
Continuous flow measurement
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
permit. Sampling shall be conducted on weekdays except where holidays or other disruptions of normal operations
prevent weekday sampling. If sampling is required for all seven days of the week for any permit parameter(s), that
requirement will be so noted on the Effluent Limitations and Monitoring Page(s).
DWR or "the Division"
The Division of Water Resources, Department of Environment and Natural Resources.
Effluent

Facility Closure
Cessation of all activities that require coverage under this NPDES permit. Completion of facility closure will allow this
permit to be rescinded.
Geometric Mean
The Nth root of the product of the individual values where N = the number of individual values. For purposes of
calculating the geometric mean, values of "0" (or "< [detection level]") shall be considered = 1.
Grab Sample
Individual samples of at least 100 mL collected over a period of time not exceeding 15 minutes. Grab samples can be
collected manually. Grab samples must be representative of the discharge (or the receiving stream, for instream
samples).

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 0) 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 Throuuh
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 [I 5A 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.
Section B. Publicly Owned Treatment Works (POTWs)
Version 1110912011.1

NPDES Permit Standard Conditions
Page 15 of 18
All POTWs must provide adequate notice to the Director of the following [40 CFR 122.42(b)]:

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.
Section C. Municipal Control of Pollutants from Industrial Users.
1. Effluent limitations are listed in Part I of this permit. Other pollutants attributable to inputs from Industrial Users
discharging to the POTW may be present in the Permittee's discharge. At such time as sufficient information
becomes available to establish limitations for such pollutants, this permit may be revised to specify effluent
limitations for any or all of such other pollutants in accordance with best practicable technology or water quality
standards.
2. Prohibited Discharges
a. The Permittee shall develop and enforce their Pretreatment Program to implement the prohibition against the
introduction of pollutants or discharges into the waste treatment system or waste collection system which

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;
(3) 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; N
(5) 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 (1047)
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;
(7) 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
(8) Any trucked or hauled pollutants, except at discharge points designated by the POTW.
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

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 EA 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.
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
complete.
E.1. Required Tests. EMuwd toxicity tests with multiple species are in progress and will be submitted at a later date.
Indicate then ber of whole effluent toxicity tests conducted in the past four and one-half years.
ronic acute [Testing is ongoing with one test completed to date. Additional test to be submitted.

ADDITIONAL INFORMATION
KILLIAN CREEK WWTP NPDES FORM 2A APPLICATION
NPDES Number: NCO088722
The following information is submitted as additional information to the NPDES Permit Application for the Killian
Creek WWTP:
Item # A.4 Collection System Information
The Killian Creek WWTP 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 WWTP 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 WWTP (NPDES
Permit #NC0074012) and the diversion of flow from this facility to the Killian Creek WWTP plus future planned
local area development are expected increase the future flow to the Killian Creek WWTP that will approach the
current permitted capacity of 1.68 mgd. To accommodate the additional flow, Lincoln County proposes to
proceed with improvements to accommodate a permitted capacity expansion to 3.35 mgd. These
improvements are proposed to include the following plant equipment additions with a completion date
projected for September 2016:
*Ten (10) aeration diffuser assemblies within the sequencing batch reactor basins (SBR).
*One (1) SBR aeration blower.
*Two (2) post SBR equalization pumps.
•One (1) effluent filter unit.
*One (1) dual bank ultraviolet disinfection unit in existing effluent channel.
*One (1) aerobic digestion blower.
*One (1) rotary lobe sludge pump.
*One (1) rotary filter press.
The proposed equipment additions are to allow an increase in the plant capacity to 3.35 mgd and are not
associated with any imposed regulatory compliance or implementation schedules. These equipment additions
and several other plant modifications currently under consideration are to be accomplished in accordance with
the NCDER "Authorization to Construct" permitting program.

A. LIQUID TRAIN PROCESS FLOW DIAGRAM @ Q =1.68 MGD
1. Headworks
Wastewater enters the plant at the plant headworks. The plant headworks system includes a
mechanically cleaned cylindrical bar screen, by-pass manually cleaned bar screen, vortex grit
collector with a grit classifier and influent parshall flume.
The mechanically cleaned screen removes solids greater than '/4" diameter. Screening from
the mechanical screen are washed and dewatered in an auger screw conveyor and placed into
a dumpster for landfill disposal. The manually cleaned bar screen with 1" bar openings
serves as a backup in event of failure of the mechanical screen.
The vortex grit separator is provided for removal of grit material potentially damaging to
downstream equipment. Grit removed from the wastewater is transferred to a grit classifier
for washing and dewatering in an auger conveyor as it is transferred into a dumpster for
landfill disposal.
An influent 24" Parshall flume and ultrasonic flow meter is provided for monitoring and
record influent flows and providing input to the influent sampler for flow proportional flow
sampling.
2. Sequencing Batch Reactors
Two sequencing batch reactors (SBR) provide biological treatment of the wastewater for
organic and solids reduction. Each SBR reactor includes a floating mixer for basin mixing,
fine bubble diffused aeration assemblies for aeration, floating decanters for effluent removal
and a sludge pump for transfer of waste activated sludge to the aerobic digesters. The SBR
process includes eight (8) potential phases of operation as follows:
• Static fill -
fill with not mixing or aeration
• Mixed fill -
fill with mixing without aeration
• Aerated fill -
fill with mixing and aeration
• React -
mixing and aeration with no fill
• Settle -
no mixing or aeration
• Decant -
removal of effluent supernatant
• Sludge Wasting
removal of sludge
• Idle -
no mixing or aeration
Wastewater is rotated between the SBR basins on a time cycle or based upon level.
Equipment redundancy is provided with multiple blowers with one unit provided as a reserve
in event of mechanical problems with either of the other two units. There is one (1)
submersible waste activated sludge transfer pump in each SBR basin with a shelf spare pump
maintained in storage in event of mechanical problems.
Page 1 of 4

NARRATIVE DESCRIPTION OF PROCESS FLOW DIAGRAMS
KILLIAN CREEK WWTP
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
capable of treating up to 4.2 MGD per bank and providing 100% backup when one bank is
taken out of service. The ultraviolet system includes a final effluent V-notch weir and
ultrasonic flow meter for final effluent monitoring, recording and pacing an automatic flow
proportional sampler.
6. Effluent Reaeration
Final effluent from the ultraviolet disinfection passes through a static reaeration structure in
route to the discharge point at Killian Creek. Aeration is provided by turbulence created in
the effluent flow as it encounters velocity baffles and the flow drops in elevation across the
structure.

NARRATIVE DESCRIPTION OF PROCESS FLOW DIAGRAMS
KILLIAN CREEK WWTP
B. SOLIDS HANDLING PROCESS FLOW DIAGRAM @ Q =1.68 MGD
1. Aerobic Sludge Digesters
A two stage aerobic sludge digestion process is proposed capable of producing a final
biosolids product meeting the 40 CFR 503 requirements for Class B biosolids complying
with the pathogen reduction (mean cell residence of 60 days at 15' C) and vector attraction
requirements (38% reduction of volatile solids).
Waste activated sludge from the SBR system is first pumped into Aerobic Digester No. 1
where it is decanted to 2% solids, mixed and aerated to achieve volatile solids reduction. The
sludge is then transferred to Digester No. 2 for further mixing, aeration and decanting to
maintain a minimum 2% solids consistency. Digester mixing is provided by a floating mixer
in each digester with aeration provided by coarse bubble diffusers. Three (3) positive
displacement blowers are provided with one unit for each digester and a third blower
providing standby capacity to either digester.
As the digestion process is completed, the final Class B biosolids maybe transferred to either
the sludge holding tank or directly to liquid tank trucks for land application.
2. Sludge Holding Tank
The sludge holding tank provides additional storage for the stabilized biosolids prior to
transfer to the dewatering process or liquid sludge disposal tank trucks. The storage tank
includes two floating mixers and a coarse bubble diffused aeration system. Periodic aeration
is possible by temporary diversion of air from Digester #2.
3. Sludge Pump Station
The sludge pump station includes a sludge macerator to reduce any large solids materials
potentially causing interference in the dewatering process and two (2) rotary lobe transfer
pumps. The rotary lobe transfer pumps are variable speed pumps controlled by the sludge
dewatering rotary press system to feed sludge to the dewatering process. One of the rotary
lobe pumps serves as a backup with the other used for normal dewatering operations.
4. Rotary Press Sludge Dewatering System
The rotary press sludge dewatering system receives waste biosolids transferred from the
sludge holding tanks by the rotary lobe sludge transfer pumps. A polymer is added and the
mixture flocculated as it is feed to the rotary press for final dewatering to produce a final
biosolids consistency capable of passing the paint filter test for landfill disposal. The
dewatered sludge is then transferred directly to the Lincoln County landfill.
5. Alternative Liquid Land Application
The plant has piping options permitting the transfer of acceptable liquid biosolids directly to
a truck for transfer to approved land application sites. Prior to land application, the biosolids
must be confirmed to meet the required regulatory requirements for pathogen and vector
attraction.

C. POWER SUPPLY SCHEMATIC DIAGRAM @ Q =1.68 AND 3.35 MGD
The Killian Creek WWTP is supplied with a primary power source with an emergency secondary
power supply from a diesel fuel engine generator. The engine generator set is each capable of
providing secondary power to maintain the operation of the WWTP operations in event of loss of
the primary power.
An automatic transfer switch and controls are provided to automatically start the engine
generator upon loss of the primary power supply and transfer to the secondary power from the
engine generator. Upon re-establishment of the primary power source, the engine generator
operation will be terminated and power supply transferred back to the primary supplier.
Upon loss of primary power at the WWTP, the SCADA system will provide an alarm at the
WWTP Lab/Operations building control panel advising of the loss of primary power and
activation of the emergency engine generator set.

Two sequencing batch reactors (SBR) provide biological treatment of the wastewater for
organic and solids reduction. Each SBR reactor includes a floating mixer for basin mixing,
fine bubble diffused aeration assemblies for aeration, floating decanters for effluent removal
and a sludge pump for transfer of waste activated sludge to the aerobic digesters. The SBR
process includes eight (8) potential phases of operation as follows:
• Static fill - fill with not mixing or aeration
• Mixed fill - fill with mixing without aeration
• Aerated fill - fill with mixing and aeration
• React - mixing and aeration with no fill
• Settle - no mixing or aeration
• Decant - removal of effluent supernatant
• Sludge Wasting removal of sludge
• Idle - no mixing or aeration
Wastewater is rotated between the SBR basins on a time cycle or based upon level.
Equipment redundancy is provided with multiple blowers with one unit provided as a reserve
in event of mechanical problems with either of the other two units. There is one (1)
submersible waste activated sludge transfer pump in each SBR basin with a shelf spare pump
maintained in storage in event of mechanical problems.
The SBR system design capacity is to be increased from 1.68 mgd to 3.35 mgd by the
addition o" Muni

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. The current
system includes three (3) transfer pumps. Expansion from 1.68 mgd to 3.35 mgd capacity is
to be accomplished by the addition o
4. Effluent Filters
Effluent filtration is currently provided by two (2) 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.
Expansion from 1.68 mgd to 3.35 mgd is to be accomplished by the additio
5. Ultraviolet Disinfection
The ultraviolet disinfection system provides for reduction of fecal coliform. The ultraviolet
system currently includes two banks with 3 modules of 30 ultraviolet lamps capable of
treating up to 4.2 mgd per bank and providing 100% backup when one bank is taken out of
service. Expansion from 1.68 mgd to 3.35 mgd will include the addition of/�
The ultraviolet system includes a final effluent V-notch weir and ultrasonic flow meter for
final effluent monitoring, recording and pacing an automatic flow proportional sampler.
6. Effluent Reaeration
Final effluent from the ultraviolet disinfection passes through a static reaeration structure in
route to the discharge point at Killian Creek. Aeration is provided by turbulence created in
the effluent flow as it encounters velocity baffles and the flow drops in elevation across the
structure.

B. SOLIDS HANDLING PROCESS FLOW DIAGRAM @ Q = 3.35 MGD
1. Aerobic Sludge Digesters
A two stage aerobic sludge digestion process is proposed capable of producing a final
biosolids product meeting the 40 CFR 503 requirements for Class B biosolids complying
with the pathogen reduction (mean cell residence of 60 days at 150 C) and vector attraction
requirements (38% reduction of volatile solids).
Waste activated sludge from the SBR system is first pumped into Aerobic Digester No. 1
where it is decanted to 2% solids, mixed and aerated to achieve volatile solids reduction. The
sludge is then transferred to Digester No. 2 for further mixing, aeration and decanting to
maintain a minimum 2% solids consistency. Digester mixing is provided by a floating mixer
in each digester with aeration provided by coarse bubble diffusers. Three (3) positive
displacement blowers are provided with one unit for each digester and a third blower
providing standby capacity to either digester. The proposed expansion to 3.35 mgd plant
capacity will add one
As the digestion process is completed, the final Class B biosolids may be transferred to either
the sludge holding tank or directly to liquid tank trucks for land application.
2. Sludge Holding Tank
The sludge holding tank provides additional storage for the stabilized biosolids prior to
transfer to the dewatering process or liquid sludge disposal tank trucks. The storage tank
includes two floating mixers and a coarse bubble diffused aeration system. Periodic aeration
is possible by temporary diversion of air from Digester #2.
3. Sludge Pump Station
The sludge pump station includes a sludge macerator to reduce any large solids materials
potentially causing interference in the dewatering process and two (2) rotary lobe transfer
pumps. A third rotary lobe pump is to be added for the proposed expansion to 3.35 mgd
capacity. The rotary lobe transfer pumps are variable speed pumps controlled by the sludge
dewatering rotary press system to feed sludge to the dewatering process. One of the rotary
lobe pumps will serves as a backup with the other pumps used for normal dewatering
operations.
4. Rotary Press Sludge Dewatering System
The rotary press sludge dewatering system receives waste biosolids transferred from the
sludge holding tanks by the rotary lobe sludge transfer pumps. A polymer is added and the
mixture flocculated as it is feed to the rotary press for final dewatering to produce a final
biosolids consistency capable of passing the paint filter test for landfill disposal. The
dewatered sludge is then transferred directly to the Lincoln County landfill.
is proposed to be
added with the plant expansion from 1.68 mgd to 3.35 mgd capacity.

5. Alternative Liquid Land Application
The plant has piping options permitting the transfer of acceptable liquid biosolids directly to
a truck for transfer to approved land application sites. Prior to land application, the biosolids
must be confirmed to meet the required regulatory requirements for pathogen and vector
attraction.
C. POWER SUPPLY SCHEMATIC DIAGRAM @ Q =1.68 AND 3.35 MGD
The Killian Creek WWTP is supplied with a primary power source with an emergency
secondary power supply from a diesel fuel engine generator. The engine generator set is
each capable of providing secondary power to maintain the operation of the WWTP
operations in event of loss of the primary power.
An automatic transfer switch and controls are provided to automatically start the engine
generator upon loss of the primary power supply and transfer to the secondary power from
the engine generator. Upoh re-establishment of the primary power source, the engine
generator operation will be terminated and power supply transferred back to the primary
supplier.
Upon loss of primary power at the WWTP, the SCADA system will provide an alarm at the
WWTP Lab/Operations building control panel advising of the loss of primary power and
activation of the emergency engine generator set.
The emergency power supply was initially sized for the plant operation at 3.35 mgd and no
modifications are requires for the proposed equipment additions associated with the
expansion to 3.35 mgd.

Dear Mr. Chamblee:
Enclosed with this letter is a copy of the draft permit renewal for your facility. Please review this
draft carefully to ensure thorough understanding of the conditions and requirements it contains.
There are several changes from the existing permit, including the following:
• The permit includes an intermediate flow tier for 2.5 MGD. The flow trigger to go to the
next tier will be when the calendar year average flow exceeds 90% of permitted flow. Special
Condition A. (6) includes the requirements to notify the Division when the flow trigger is
meet.
• Monitoring for total residual chlorine was eliminated from the permit since UV is used as the
disinfection method.
• Quarterly monitoring for total zinc was added to the effluent monitoring requirements. Total
zinc was detected during the effluent pollutant scan at concentrations greater than the water
quality standard.
• The requirement to perform effluent pollutant scans was modified from annual to three
times during your permit cycle. See Special Condition A.(3). 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

A. (4) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
The permittee shall conduct quarterly chronic toxicity tests using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, or subsequent
versions.
The effluent concentration defined as treatment two in the procedure document is 52% (1.68 MGD)/ 62%
(2.5 MGD) / 68% (3.35 MGD). The testing shall be performed as a Ceriodaphnia dubia 7-day pass/fail test.
The tests will be performed during the months of January, April, July and October. These months
signify the first month of each three month toxicity testing quarter assigned to the facility. Effluent
sampling for this testing must be obtained during representative effluent discharge and shall be performed at
the NPDES permitted final effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the month in which it was formed, using the parameter code TGP3B.
Additionally, DWR Form AT-1 (original) is to be sen following address:

made
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as will as all dose/response data. Total residual chlorine of
the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the
waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is
required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test
form indicating the facility name, permit number, pipe number, county, and the month/year of the report
with the notation of "No Flow" in the comment area of the form. The report shall be submitted to the
Water Sciences Section at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, then monthly
monitoring will begin immediately. Upon submission of a valid test, this monthly test requirement will
revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division
of Water Resources indicate potential impacts to the receiving stream, this permit may be re -opened and
modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival, minimum control organism reproduction, and appropriate environmental controls, shall
constitute an invalid test and will require immediate follow-up testing to be completed no later than the last
day of the month following the month of the initial monitoring.

SUMMARY:
The Killian Creek WWI'P started operations of the 1.68 MGD WWTP in 2010. The existing
WWTP consists 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 3.38 MGD 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. Killian Creek is listed as impaired in the 2014 303(d) list for fair fish community.

SUMMARY OF PROPOSED CHANGES
1. The supplement 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 will 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. Quarterly 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.

A. (3) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 52/68%.
The permit holder shall perform at a minimum, quarferl 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 January, April, July and October. 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' -1) for the months in which tests were performed, using the parameter code TGP3B for the MR
pass/fail results and THP3B for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the
following address:
Attention: NC DENR / DWQ / Environmental Sciences Section

after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate signature.
Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the
Permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the facility
name, permit number, pipe number, county, and the month/year of the report with the notation of "No Flow" in the
comment area of the form. The report shall be submitted to the Environmental Sciences Branch at the address cited
above.
Should the Permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be
required during the following month.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water
Quality indicate potential impacts to the receiving stream, this permit may be re -opened and modified to include
alternate monitoring requirements or limits.
If the Permittee monitors any pollutant more frequently then required by this permit, the results of such monitoring
shall be included in the calculation & reporting of the data submitted on the DMR & all AT Forms submitted.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism
survival, minimum control organism reproduction, and appropriate environmental controls, shall constitute an invalid
test and will require immediate follow-up testing to be completed no later than the last day of the month following
the month of the initial monitoring.

PART II
STANDARD CONDITIONS FOR NPDES PERMITS
Section A. Definitions
2/Month
Samples are collected twice per month with at least ten calendar days between sampling events. These samples shall
be representative of the wastewater discharged during the sample period.
3/Week
Samples are collected three times per week on three separate calendar days. These samples shall be representative of
the wastewater discharged during the sample period.
Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act (CWA), as amended, 33 USC 1251, et.
seq.
Annual Average
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal
coliform, the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
Bypass
The known diversion of waste streams from any portion of a treatment facility including the collection system, which
is not a designed or established or operating mode for the facility.
Calendar Day
The period from midnight of one day until midnight of the next day. However, for purposes of this permit, any
consecutive 24-hour period that reasonably represents the calendar day may be used for sampling.
Calendar Week
The period from Sunday through the following Saturday.
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 nil 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
(3) 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
Version 712009

NPDES Permit Standard Conditions
Page 2 of 18
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.
➢ Permittees with wastewater treatment systems whose detention time exceeds 24 hours shall collect
effluent grab samples at least every six hours; there must be a minimum of four samples during a 24-hour
sampling period.
Continuous flow measurement
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

RE. Killian Creek WWTP, NPDES Permit NC 0088722 Renewal
Dear Mrs. Sprinkle,
The purpose of this letter is to request renewal of the Killian Creek WWTP NPDES Permit,
NC 0088722, for five more years. This plant is not yet in service but, is under construction.
Construction began on June 1, 2009 and we expect to have this 1.6 mgd plant on line in late
2010. We have filled out the NPDES 2A Application to the extent that we can.
As far as a sludge management plan referred to in your letter, this plant will dispose of the

review and issuance of the ATC can not be completed until the subject NPDES
permit has been properly noticed and a final permit issued.
e. Description of existing or substantially constructed WWT facilities: There are no
existing WWT facilities at this time.
£ Description of proposed WWT facilities: The applicant proposes to construct a
WWT facility consisting of an influent pump station with a manually cleaned bar
screen, a headworks consisting of a mechanical bar screen, a vortex grit separator, a
grit classifier, and an influent parshall flume with an ultrasonic flow meter. From
there the wastewater will enter 2 sequencing batch reactors, a post equalization basin,
effluent filters, ultraviolet disinfection and effluent reaeration. WAS will be sent to
one of two aerobic digesters. Also included in the solids handling process will be a
sludge holding basin with floating mixers, and a rotary sludge press. Stand-by power

3. Important SOC/JOC or Compliance Schedule dates: There is no SOC or Compliance
Schedule being considered at this time.
4. Alternative Analysis Evaluation: There is no economically feasible alternative known
outside of the proposed discharge.
PART IV - EVALUATION AND RECOMMENDATIONS
The applicant, Lincoln County (LC), requests the issuance of an NPDES Permit for a
proposed WWT facility to be built in eastern Lincoln County. This facility will serve an area that is
experiencing heavy growth and development, which has resulted in capacity and compliance issues
at LC's Middle Forney Creek WWTP located a few miles upstream. Once completed, wastewater
flows in excess of the hydraulic capacity of the Middle Forney Creek WWTP will be sent down to
the proposed Killian Creek WWTP for treatment.
LC has chosen a sequencing batch reactor (SBR) as the method of treatment. The
applicant's engineer indicated that one of the primary reasons for the use of SBR technology is that
it will allow the WWTP's operator greater flexibility in managing in -plant process control during
the first few years of plant operation when influent flows are expected to be much lower than
hydraulic design capacity. This Office has not as yet received a copy of the ATC for this facility, so
there may be some changes in the final design pending an agency review. An SBR WWT facility
with tertiary treatment should be capable of complying with the effluent limitations as set forth in
the draft NPDES permit.
Pending a final approval of the draft permit, it is recommended that a final NPDES permit be
issued as requested.

NARRATIVE DESCRIPTION OF PROCESS FLOW DIAGRAMS
KILLIAN CREEK WWTP
A. LIQUID TRAIN PROCESS FLOW DIAGRAM
1. Influent Pump Station
Wastewater is conveyed to the Killian Creek Influent Pump Station by the Killian
Creek gravity sewer. The influent pump station includes a hydraulically operated
sewage grinder and a by-pass manually cleaned bar screen for reduction or removal
of large solid materials potentially damaging to the pumps. Duplex submersible
pumps, each sized for a peak flow rate of 2900 gpm/each (2.5 x average daily flow),
transfer the incoming wastewater to the Killian Creek WWTP headworks through a
20" force main.
2. Headworks
The plant headworks system includes a mechanically cleaned cylindrical bar screen
for removal of solids greater than V" diameter with a manually cleaned bar screen
serving as a backup in event of failure of the mechanical screen. Screening from the
mechanical screen are washed and dewatered in an auger screw conveyor and placed
into a dumpster for landfill disposal.
A vortex grit separator is provided for removal of grit material potentially damaging
to downstream equipment. Grit removed from the wastewater is transferred to a grit
classifier for washing and dewatering in an auger conveyor as it is transferred into a
dumpster for landfill disposal.
An influent 24" Parshall flume and ultrasonic flow meter is provided for monitoring
and record influent flows and providing input to the influent sampler for flow
proportional flow sampling.
3. Sequencing Batch Reactors
Two sequencing batch reactors (SBR) provide biological treatment of the wastewater
for organic and solids reduction. Each SBR reactor includes a floating mixer for
basin mixing, fine bubble diffused aeration assemblies for aeration, floating decanters
for effluent removal and a sludge pump for transfer of waste activated sludge to the
aerobic digesters. The SBR process includes seven (7) potential phases of operation
as follows:
• Mixed fill - mixing without aeration
• React fill - mixing and aeration
• React - mixing and aeration
• Settle - no mixing or aeration
• Decant & sludge waste - removal of effluent supernatant and waste sludge
• Idle - no mixing or aeration
Wastewater is rotated between the SBR basins on a time cycle or based upon level.
Equipment redundancy is provided with multiple blowers with one unit provided as a
reserve in event of mechanical problems with either of the other two units. There is
Page 1 of 4

NARRATIVE DESCRIPTION OF PROCESS FLOW DIAGRAMS
KILLIAN CREEK WWTP
one (1) submersible waste activated sludge transfer pump in each SBR basin with a
shelf spare pump maintained in storage in event of mechanical problems.
4. 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.
5. Effluent Filters
Effluent filtration is.provided by two (2) cloth disk filter units containing eight (8)
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/l 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.
6. Ultraviolet Disinfection
The ultraviolet disinfection system provides for reduction of fecal coliform utilizing
ultraviolet light. The ultraviolet system includes two banks with 4 modules of 32
lamps capable of treating up to 4.2 MGD per bank and providing 100% backup when
one bank is taken out of service. The ultraviolet system includes a final effluent V-
notch weir and ultrasonic flow meter for final effluent monitoring, recording and
pacing an automatic flow proportional sampler.
7. Effluent Reaeration
Final effluent from the ultraviolet disinfection passes through a static reaeration
structure in route to the discharge point at Killian Creek. Aeration is provided by
turbulence created in the effluent flow as it encounters velocity baffles and the flow
drops in elevation across the structure.

NARRATIVE DESCRIPTION OF PROCESS FLOW DIAGRAMS
KILLIAN CREEK WWTP
B. SOLIDS HANDLING PROCESS FLOW DIAGRAM
1. Aerobic Sludge Di eg_ stees
A two stage aerobic sludge digestion process is proposed capable of producing a
final biosolids product meeting the 40 CFR 503 requirements for Class B biosolids
complying with the pathogen reduction (mean cell residence of 60 days at 15' C) and
vector attraction requirements (38% reduction of volatile solids).
Waste activated sludge from the SBR system is first pumped into Aerobic Digester
No. 1 where it is decanted to 2% solids, mixed and aerated to achieve volatile solids
reduction. The sludge is then transferred to Digester No. 2 for further mixing,
aeration and decanting to maintain a minimum 2% solids consistency. Digester
mixing is provided by a floating mixer in each digester with aeration provided by
coarse bubble diffusers. Three (3) positive displacement blowers are provided with
one unit for each digester and a third blower providing standby capacity to either
digester.
As the digestion process is completed, the final Class B biosolids maybe transferred
to either the sludge holding tank or directly to liquid tank trucks for land application.
2. Sludge Holding Tank
The sludge holding tank provides additional storage for the stabilized biosolids prior
to transfer to the dewatering process or liquid sludge disposal tank trucks. The
storage tank includes two floating mixers and a coarse bubble diffused aeration
system. Periodic aeration is possible by temporary diversion of air from Digester #2.
3. Sludge Pump Station
The sludge pump station includes a sludge macerator to reduce any large solids
materials potentially causing interference in the dewatering process and two (2) rotary
lobe transfer pumps. The rotary lobe transfer pumps are variable speed pumps
controlled by the sludge dewatering rotary press system to feed sludge to the
dewatering process. One of the rotary lobe pumps serves as a backup with the other
used for normal dewatering operations.
4. Rotary Press Sludge Dewatering System
The rotary press sludge dewatering system receives stabilized biosolids transferred
from the sludge holding tanks by the rotary lobe sludge transfer pumps. A polymer is
added and the mixture flocculated as it is feed to the rotary press for final dewatering
to produce a final biosolids consistency of approximately 20% or greater final solids.
The dewatered sludge may then be land applied in approved disposal sites or
transferred directly to the Lincoln County landfill.

NARRATIVE DESCRIPTION OF PROCESS FLOW DIAGRAMS
KILLIAN CREEK WWTP
C. POWER SUPPLY SCHEMATIC DIAGRAM
The Killian Creek Influent Pump Station and WWTP are each supplied with separate
primary power sources with a secondary power supply from a diesel fuel engine
generator. The engine generator sets are each capable of providing secondary power to
maintain the operation of the pump station or WWTP operations in event of loss of the
primary power.
An automatic transfer switch and controls are provided at each location to automatically
start the engine generator upon loss of the primary power supply and transfer to the
secondary power from the engine generator. Upon re-establishment of the primary power
source, the engine generator operation will be terminated and power supply transferred to
the primary supplier.
Upon loss of primary power at either the influent pump station or WWTP, the SCADA
system will provide an alarm at the WWTP Lab/Operations building control panel
advising of the loss of primary power and activation of the emergency engine generator
set.

'This letter is iii response to your March 21, 2003 request for speculative effluent limits fur a proposed wastewater
treatment plant iu Lincoln CounR. 'Tlic request includes iwu locations at two flows each. This letter addresses flows of
4 MGD and 7 1\4GD at the following locations: Killian Creek near the intersection of Killian Crcck and its tributary
Forney Creek (SITE 1),
N/u,
Engineering Airvr-moVes Analysis j]=,X V Plcase note that the Division cannot guarantee that an NPDES permit will
be issued with Ihrse speculative limits. Final decisions can only be made. after the Division receA-es and evaluates a
formal permit application for the proposed discharge. In accordance ,vith the North Carolina General Statutes, the
practicable wastewater treatment and disposal alternative with the least adverse impact on the environment is required
to be implemented. Therefore, as a component of all NPDES pernvt applications for new or expanding flow, a
detailed engineering alternatives analysis (E.-1) must be prepared. The EAA trust justify requested flows, and provide
an analysis of potential .vastewater trcatment alternatives. Alternatives to a surface water discharge, such as spray/drip
irrigation, wastewater reuse, or inflow/infiltration reduction, are considered to he environmentally preferable. A copy
of the EAA requirements is attached to this letter. Permit applications for new or expanding flow will be returned
as incomplete if all EAA requirements are not adequately addressed. If you have any questions regarding these
requirements, please contact the IDWQ NPDES Unit at 919-733-5083.
State Environmental Pobcv \ct (SEPA ) FA/EIS Kequirement+ A SEIIA EA/EIS document must be prepared for all
projects that 1) need a permit; 2) use public money or affect public lands; and 3) might have a putenual to sigriiGcatidy
impact the environment. For new wastewater discharges, significant impact is defined as a proposed discharge of
>500,000 gpd and producing, an instream waste concentration of > 33% based on summer 7Q10 flow conditions.
Since the proposed facility is a new discharge meeting these criteria, you must prepare a SEPA clocurnent that
evaluates the potential for impacting the quality of the environment. The NPDES Unit will not accept an
NPDES permit application for the proposed expansion until the Division has approved the SEPA document
and sent a Finding of No Significant Impact (PONSI) to the State Clearinghouse for review and comment. A
SEPA Environinellial Assessment (LA) should contain a clear jusdficadou for the proposed project. If the SEPA EA
demonstrates that lhe: project may result in a significant adverse effect on the quality of the environment, you must then
prepare a SI:P/t 1 :IS (F.m iruiuncntal Impact Statement). Since your proposed facility is subject to SEPA, the EAA
requirements discussed above will need to be folded intn the SEPA document. The SEPA process will be
delayed if all EAA requirements are not adequately addressed. If you have.. any questions regarding SEPA
EA/171S requirements, please contact Alex Marks wish the l)\\'l') Planning Branch at [phone], ext. 555.

ADDITIONAL INFORMATION
KILLIAN CREEK WWTP NPDES FORM 2A APPLICATION
NPDES Number: Undetermined — New Facility
The following information is submitted as additional information to the NPDES Permit Application for the Killian
Creek WWTP:
Item # A.4 Collection System Information
The planning area for this project includes a 2025 population projection of 44,546 to be served by the collection
system. Wastewater treatment will be provided by the existing Lincoln County 0.975 mgd Middle Forney Creek
WWTP and the proposed future 3.35 mgd Killian Creek WWTP. It is estimated that the population served by
each plant will closely approximate the ratio of the plant capacity. Accordingly, it is projected that 10,042
(22.54%) population will be served by the Middle Forney Creek WWTP and the remaining 34,504 (77.46%)
population will be served by the new Killian Creek WWTP at design capacity.
Item BA Inflow and Infiltration
The proposed new Killian Creek WWTP will receive flow from both the existing and future collection sewer
system. An infiltration and inflow analysis is included within the Section 3.4 of the approved Preliminary
Engineering Report. This analysis concluded the following:
1. The estimated infiltration rate within the existing collection system was found to be less than 3,000 gpd
per inch diameter mile guideline consider as excessive infiltration.
2. The estimated inflow was found to be less than the 275 gpd/capita considered as excessive inflow.

December 19, 2006
NOTE: Please provide a response to all of the comments on a "comment for comment" basis.
Where appropriate, add or revise narrative in the text of the Engineering Report that
addresses the issues discussed in the comments. In addition, the comments and
responses may be included as a part of the report (e.g. in an appendix).
I. General:
1. Please note that approval of the Engineering Report (ER) does not constitute approval of
sole source procurement. Plans and specifications must comply with N.C. General
Statute Chapter 133, Section 3, prior to their approval.
WKD Response
It is acknowledged that the construction plans and specifications are to comply with NC
General Statute, Chapter 133, Section 3 — regarding competitive items and substitution of
materials.
2. A loan from the North Carolina Water Pollution Control Revolving Loan Fund (SRF) is
contingent on the review and approval of the proposed loan by the Local Government
Commission.
WKD Response
It is acknowledged that a loan from the North Carolina Water Pollution Control
Revolving Loan Fund (SRF) in contingent upon approval of the loan by the Local
Government Commission.
3. Please be advised that the county should have an approved user charge system and sewer
use ordinance to provide for funding the sewer system operation and maintenance and
repayment of the SRF loan. The user charge system and sewer use ordinance must be
approved before a loan recipient can get more than one reimbursement request processed.
The two documents do not have to be adopted by the loan recipient until the end of
construction.
WKD Response
Lincoln County has an approved user charge system and sewer use ordinance for funding
and repayment of the SRF Loan. A copy of these documents is included within
Appendix G of the Engineering Report.

rock removed for the construction. The only road crossing within the project is for the
proposed 12" diameter force main crossing of Little Egypt Road near the existing
Middle Forney Creek WWTP. Additional borings are not proposed at this location at
this time.
e) NCDOT Encroachment Agreements and Railroad Encroachment Agreements.
Copies of these agreements must be provided in the specifications, or it must be
documented how all construction requirements, associated with the agreements,
have been incorporated in the plans;
WKD Response
An NCDOT encroachment agreement will be obtained for the proposed force main
construction adjacent to and crossing under Little Egypt Road and incorporated into
the construction specifications. There are no railroad crossings or easements from a
railroad company anticipated within this project.
f) All construction easements, permanent easements, and rights -of -way. These
easements and rights -of -way must be shown on the plans;
WKD Response
The construction plans will show construction and permanent easements/right-of-ways
associated with the project.
g) NPDES Permit when the project involves a new discharging facility or expansion to an
existing one;
WKD Response
An application for a new NPDES Permit will be submitted upon issuance of the
Findings of No Significant Impact (FNSI). Speculative effluent limits for the
proposed Killian Creek WWTP were issued by the North Carolina Division of Water
Quality on March 18, 2004 and are included within Appendix A of the Engineering
Report.
h) Currently, SRF loan participation in Laboratory/Administration buildings funding is
limited to $160 per square foot. This participation amount is revised annually based
on construction cost indices. Please provide a total square footage and list these
buildings separately in the bid form so that eligible costs can be determined after
receipt of bids.
WKD Response
The construction bid form will include an itemized listing of site buildings and cost
based upon a square footage unit cost.
5. The report appears to indicate that the expansion of the Middle Forney Creek WWTP
is a separate project and is not part of the scope of the selected alternative and not
intended to be a part of the Finding of No Significant Impact (FNSI). Please confirm
whether or not this is true.

III. Section 3: Current Situation
1. Page 3-1 and Figure 3.1: Regarding the project planning area and its boundaries, the
areas shown on Figure 3.1 are very different from the ones on Figures 2.1, 4.1 and
5.1. Please explain.
WKD Response
Figure 3.1 shows the area currently served by ELCWSD with existing sewer lines,
pump stations and force mains within the Catawba Springs Township. This service
area currently includes the Forney Creek sewershed and a small section of the Killian
Creek sewershed. Figures 2.1, 4.1 and 5.1 reflect the planning area designated for
future service expansion consistent with the County's 20 year capital improvements
plan. The future service area includes the area of Lincoln County east of the City of
Lincolnton including the Hoyle Creek, Leepers Creek, Killian Creek and Forney Creek
drainage basins as shown on Figure 4.1.
2. Page 3-1: If available, provide documentation (e.g. a letter from the County Health
Dept.) concerning septic systems that are currently failing.
WKD Response
Documentation from Mr. Scott Snead with the Lincoln County Environmental Heath
Department concerning failing septic tank systems has been included in Appendix L.
3. Page 3.2: Please clarify the current sewer customer number in the ELCWSD district.
On page 2-2, the Engineering Report states that ELCWSD serves 2491 customers;
however, on page 3-2, the number is 2272; and on page 3-4, 2352.
WKD Response
At the date of the Engineering Report preparation in late 2005, the ELCSD had a total
of 2491 sewer connections (2272 water and sewer customers, 161 sewer only
customers and 58 industrial/commercial customers) as reflected on page 2-2. The
referenced sewer connections totaling 2272 on page 3-2 reflects only the water and
sewer residential customers. The customer units reflected on page 3-4 of 2352 units
was the actual customer count over the period June — July, 2004 during the evaluation
of the infiltration. The Engineering Report was revised on page 2-2 and 3-2 for
agreement. Page 3-4 will remain as 2352 units.
4. Page 3-2: Please provide an update concerning the progress of the Middle Forney
Creek WWTP expansion.
WKD Response
Page 3-2 was revised to indicate that the Middle Forney Creek WWTP modifications
were completed in January, 2007.

when available and considers the projection of 80% connections within the Catawba
Springs Township and 60% connections within the Ironton Township to be a
reasonable expectation by the year 2025.
3. Page 4-1: Provide some more narrative to discuss the basis for the 78.8% growth
projection. What does this equate to in annual growth? How does it compare to the
projected Lincoln County growth rate for the same period? What was the growth rate
for the planning area for the last five years?
WKD Response
The population projections are presented within Table 3.1 based upon data obtained
from the U.S. Bureau of Census. The referenced data source reflects an overall
Lincoln County population growth of 55.34% from 63,780 to 107,933 by the year
2023 or an average growth of 2.4% per year. The year 2025 was computed using a
straight line extrapolation. As noted in Table 3.1, the Catawba Springs and Ironton
Townships are forecast to have the greatest growth with a combined population
growth from 36,022 in 2003 to 62,955 by 2025 yielding a 74.77% growth over 22
years or a compounded annual growth of 2.58% per year). This County growth
pattern to the east side of the County is heavily influenced by Lake Norman and
commute distance to the Charlotte, NC area.
4. If ELCWSD wastewater flow is re -projected and varies from the 4.1 MGD estimate,
alternative costs and other associated engineering calculations and financial estimates
should also be re -calculated.
WKD Response
The wastewater flow projections are believed to be correct; therefore, alternative costs
and engineering calculations are not necessary.
V. Section 5 - ALTERNATIVES:
1. Effective September 1, 2006, the Division's rules contained in 15A NCAC 2H have
been replaced by the new 15A NCAC 2T Rules. Minimum Design criteria for both
non -discharging and discharging facilities can now be found in the 2T Rules. Please
confirm that all the engineering designs in this proposed project will meet the 2T Rules.
A copy of the new rules can be viewed at: http://h2o.enr.state.nc.us/lau/main.html.
WKD Response
NC Administrative Code 15A NCAC 2T Rules, amended on September 1, 2006 is
acknowledged. To the best of our knowledge, the proposed wastewater facilities
planning and design will meet the minimum design requirements contained in the 2T
Rules.
1. Wastewater Conveyance Alternatives:
a. Page 5-3, On -Site Septic Systems: For new applicants, NPDES generally
requires some justification for why on -site systems are not a viable alternative
for the project area (e.g., existing septic systems are failing, County Health will
not permit on -site systems for the proposed project due to local soil constraints,
Page 7 of 17
4/ 10/2007

Items within the Serger Chernikov's (NPDES-West) letter of March 24, 2006 and
related email from Larry Horton to Bob Froneberger of August 9, 2006 have been
addressed by revisions within Section 5.3 of the Engineering Report.
b. Connection to Existing WWTP. Evaluate the possibility of connection to an
existing WWTP. NPDES generally requires the applicant to estimate the cost of
connection to an existing plant with existing sewer line within a 5-mile radius;
alternatively, if an existing plant with available capacity would not accept the
proposed discharge, a letter from the existing plant stating such, would suffice to
negate this alternative. The Mooresville Regional Office's (MRO) comments
memorandum is attached for reference. MRO requested that collection and
pumping to the c ity of Lincolnton's WWTP should be considered. Please provide
narrative to discuss this alternative and a present worth analysis.
WKD Response
Section 5.3.2 was revised to address the connection to the nearest existing area
WWTP and the upgrade of the Middle Forney Creek WWTP. The City of
Lincolnton's WWTP is in excess of 16 miles, would require overcoming an
approximate 300 foot elevation head and upgrade of the City's plant to provide
additional capacity. A letter from the City of Lincolnton addressing the capacity
issue has been added in Appendix M.
Land Application. The applicant will provide justification for the land costs used
in the spray irrigation alternative (e.g., real estate letter, internet search of current
land costs in the project vicinity, etc.). Evaluation of a drip system alternative in
addition to spray irrigation is not necessary, since spray systems generally cost less
than drip systems. Provide some documentation to support the estimated land
cost amount of $7500 to $10,000/acre.
WKD Response
Documentation of area land cost has been included within Appendix E.
A recent property sale in the area by Hecht Reality, Inc. (Century 21) closed at
13,800/acre (see attached email of January 15, 2007). Mr. Hecht further indicates
serious doubts about finding acreage tracts in the 500 to 800 acre size in this area.
Ms. Madge Huffman, Lincoln County Tax Administrator provided documentation
for "open land" in rural Lincoln County with land pricing guidelines of $2,500 to
$5,000/acre. This pricing is influenced by the significantly lower cost of land in
Western Lincoln County. While it is believed the actual cost of land will exceed
$7,500/acre, WKD has adjusted the cost of land for the land application site
evaluation to $3,500/acre and revised the related alternative cost evaluation
accordingly.
A cost of $8,500 per acre for the treatment plant site was utilized with all
alternative evaluations. The County approved the purchase of the 38.049 acre
treatment plant site (with no road frontage) on March 19, 2007 based upon
property assessments for a cost of $275,000 or $7,227 per acre. Since the purchase

WKD Response
Copies of the current ELCWSD agreements with application site property
owners have been included within Appendix N of the Engineering Report. It is
not feasible to obtain agreements for application potentially 3 years in advance.
d. Provide documentation that the landfill will accept dewatered sludge for disposal.
WKD Response
A copy of a letter of acceptance from Lincoln County has been included within
Appendix N of the Engineering Report.
4. Page 5-1.7: The "Wastewater Treatment Alternative Conclusions", including the
discussions about cost effectiveness, should be moved to appear in the report after the
present worth analysis discussion in Section 6.
WKD Response
Section 5.3.6 was renamed as "Wastewater Treatment Alternative Summary". The
actual conclusions and cost effectiveness discussions have been added to Section 6.
VI. Section 6 - PRESENT WORTH ANALYSIS:
1. Pages 6-2 and 6-4: Please confirm that there is no present worth of replacement costs
involved in this project. Otherwise, please add the costs to the Engineering Report.
WKD Response
No replacement costs have been included within the cost evaluations. A twenty year
life was assumed for all equipment. A twenty (20) year life was assumed for all
equipment.
2. Provide some narrative to briefly summarize the conclusion and recommendation of
the present worth analysis. This should include the total estimated cost of the
recommended project and a summary of the funding sources for the total cost of the
project.
WKD Response
Section 6.4 has been added to provide a narrative description of the selected
alternative and summary of the probable costs and present worth analysis.
Collection System Alternatives:

d. The sewer collection facilities that are in this project (i.e. the selected alternative)
and that will be included in the FNSI must be clearly identified on a map. The map
should include gravity & force main lines lengths and sizes and pump stations with
capacity.
WKD Response
Figure 6.1 and Figure 6.2 have been added to show the proposed Alternative #4 -
Phase I and Phase II construction of gravity sewers, force mains and pump stations.
4. Wastewater Treatment Alternatives:
a. Table 6.2: Include an additional column for the Phased SBR alternative to
provide a side -by -side comparison of the capital costs and the 20-year present
worth of the phased SBR alternative.
WKD Response
Table 6.2 has been revised to Table 6.5 and wastewater treatment Alternative #4
added to provide a cost summary for the phased construction of the SBR WWTP
(Alternative #1).
b. Provide a table for the selected alternative including the wastewater treatment
plant units and their estimated cost, engineering cost, contingency, 2% SRF
loan closing cost.
WKD Response
Table 6.6 provides an itemized cost summary of the selected alternative with the
requested cost breakdown.
c. Provide a map that shows the site plan for the selected alternative including
designation of Phase I and Phase II.
WKD Response
Figure 6.1 and 6.2 provides a map of the proposed Phase I and Phase II conveyance
system construction and Figure 6.3 provides a proposed layout plan for the
wastewater treatment facility.
d. Correct the Table name in 6.3.3 and 6.3.4 from "6.1" to "6.2".
WKD Response
This section has been revised and table reference corrected.
e. Correct the Appendix name in 6.3.4 from "E" to "F".
WKD Response
Correction was made.

b. CG&L has previously budgeted S 12M for this project. For planning purposes
and for user charge calculations, the maximum SRF loan amount that should be
assumed is $15M.
WKD Response
The SRF loan maximum amount of $15M is acknowledged. ELCWSD proposes to
fund the remaining portion of the proposed project costs from the Lincoln County
sewer fund.
c. Table 7.1 indicates that some of the annual debt service and O&M expenses will
be paid with taxes and tap -on fees. The user charge must be calculated based on
all of the debt service and O&M expenses, associated with the new project being
funded by user charges.
WKD Response
Table 7.1 has been revised to provide a separate total cost for the SRF related debt
service. The projected user charges are sufficient to provide a revenue source to
cover these costs with other operating costs funded by the capacity development,
sewer tap fees and property valuation tax. ELCWSD considers the capacity
development and sewer tap fees to be "user fees" as they are paid directly by
consumers utilizing the wastewater service.
d. Tap -on fees and other one-time sources of revenue may be used in the calculation
of the payment on the project capital cost to lower the amount of the initial debt.
These fees should be based on the expected number of initial connections (taps)
when the project commences.
WKD Response
Table 7.1 and Table 7.2 reflect the projection of capacity development fees and sewer
tap fees based upon ELCWSD records and anticipated County growth tendencies.
These fees are based upon the new connections per year. ELCWSD considers these
revenue sources to be part of the "user fees" charged directly to consumers of the
wastewater conveyance and treatment services.
e. Provide a brief table that shows the total project capital cost and all of the funding
sources that will be used to fund the project capital cost. The funding amount
should be equal to the project cost.
WKD Response
Table 7.2 has been added per foregoing request.
VIII. Section 9 - Public Participation
Public meetings in early stages of the project development are encouraged. These
meetings can be regular town board meetings in which the project is discussed. One
public hearing, with 2-week notification, is required. Some guidance concerning the
public hearing follows:

Jennifer, the Pretreatment staff of the Pretreatment, Emergency Response and Collection Systems Unit
(PERCS) have the following comments on this project, which should be forwarded to the Project
Engineer and the East Lincoln County Water and Sewer District for their consideration.
This report is titled Engineering Report for East Lincoln County Long Range Wastewater
Improvements. It will provide sewer for various industrial parks, so I contacted Charles Froneberger,
the project engineer, to ask some questions. He indicated that these sewer lines and both WWTPs
belong (or will belong) to East Lincoln County Sewer District (ELCWSD), not Lincoln County. Like
all municipal/publicly owned treatment works (POTWs), ELCWSD is/will be required by Part IV of
their NPDES permit(s) to notify the Division, and develop a Division approved Pretreatment Program
prior to accepting any wastewater from a Significant Industrial User. Please review the PERCS
Web -site at lit tp:/'cnr.statc.nS.us,'P[:RCS/ for more information. Please note it can take 6 to 12
months (sometimes more) to develop and submit all required Pretreatment Program elements and
receive Division approval and delegation. ELCWSD is urged to contact Dana Folley of PERCS at
919-733-5083, ext. 523. as soon as they can upon learning of any industrial user plans to discharge
process wastewater.
Additionally, discussions between Ms. Folley and ELCWSD's engineer Mr. Froneberger, indicated
that Forney Creek WWTP either cannot or eventually will not be able to treat all the flow proposed to
come to the WWTP. Mr. Froneberger indicated the Project proposes to address this problem by
adding sewer piping/pumping at the influent of the Forney Creek WWTP so that any excess flow
coming into the Forney Creek WWTP would be diverted over to the new Killian WWTP (the one
proposed to be constructed). PERCS Pretreatment staff wish to point out that splitting SIU flow
between two treatment plants flow will significantly complicate your Pretreatment Program, especially
your Headworks Analyses, Allocation Tables, and Long Term Monitoring Plans. Please feel free to
contact Ms. Folley to discuss this issue or any other questions.
Jennifer, thank you for the opportunity to comment. Comments from the Collection Systems staff of
PERCS will be provided separately.

RESPONSE TO ENVIRONMENTAL AGENCY REVIEW COMMENTS OF
APRIL, 2006.
Ms. Hannah Stallings
NC DWQ Construction Grants and Loans Section
Project No. CS370825-01 t
April 18, 2006 ; :•.;���
Comment 1: Please be consistent with the name of the Middle Fornr1�1a,V�TP.
Several abbreviated titles are used throughout the document.
Response: All references to this plant have been changed to read, "Middle Forney Creek
WWTP".
Comment 2: Please confirm that the Middle Forney Creek upgrade from 0.75 MGD to
0.975 MGD is not part of this project.
Response: The upgrade is not a part of this project.
Comment 3: Please clarify if this project includes the expansion of the Middle Forney
Creek WWTP or the construction of the new Killian Creek WWTP.
Response: This project includes the construction of the new Killian Creek WWTP, but
does not include the upgrade of the Middle Forney Creek WWTP. The 0.225 MGD
capacity increase at the Middle Forney Creek WWTP was required to address present
needs. Upon completion of the proposed Killian Creek WWTP, the Middle Forney
Creek WWTP will be returned to 0.75 MGD capacity.
Comment 4: The document states that the East Lincoln County Water and Sewer
District (ELCWSD) is replacing five manholes and two wet well structures to address
corrosion within the system. Please confirm that this work is not a part of this project.
Response: Confirmed. This was included in the existing facilities discussion to explain
the current wastewater collection system condition. These improvements are being
carried out separately from this project, and are associated with maintenance and / or
repair of Lincoln County's existing system.
Comment 5: Include some discussion of how urbanization creates water quality
concerns for the area.
Response: The requested discussion is included in Section 4.8.4.2 of the Environmental
Assessment.
Comment 6: There does not appear to be an immediate need for the proposed project
out of either environmental or public health concerns. Please explain.
Response: Bob F.
Documentation of septic tanks problems has been included within Appendix L. The
immediate need for the project is to meet the documented area growth.

The immediate need for the proposed project is based upon the area growth and
increasing capacity demands on the existing Middle Forney Creek WWTP. The Middle
Forney Creek WWTP was recently expanded from 0.75 mgd to 0.975 mgd. Already, the
current average daily flow plus flow commitments held by area developers has reached
90% of the expanded plant capacity. DENR has already indicated that ELCWSD should
not issue any additional flow acceptance letters until the new facility is under
construction.
Comment 7: Please provide cost estimates for each of the alternatives.
Response: Cost estimates are included in WKD Engineering Report with summaries
provided in Section 6, and detailed estimate spreadsheets provided in Appendix C and F.
Comment 8: Please conclude the alternatives analysis section with a description of the
preferred alternatives.
Response: Section 6 of the Engineering Report has been modified to conclude this
section with a description of the selected alternative.
Comment 9: The cost for projected wastewater conveyance improvements provided on
Page 6 is $40,368,600. Please confirm this price is not for the 20-year Capital
Improvements Plan, but rather the material covered in the current Engineering Report.
Response: The referenced $40,368,600 is related to the "20-Year Capital Improvement
Plan for Water and Wastewater Infrastructure - Lincoln County, NC and East Lincoln
County Water and Sewer District", prepared by Oliver, Inc. [Cost should reflect $49.6
million over the 20-year planning period].
Comment 10: The discussion of septic tank effluent pumping (STEP) systems in the
alternatives analysis section describes these systems, but does not discuss their
appropriateness for this project. Please amend the text to address this.
Response:
The report has been amended to delete the septic tank effluent pumping system from the
alternative analysis. This alternative is not desirable to ELCWSD due to potential for
infiltration/inflow within the septic tanks and high potential for odors and corrosion
within the downstream collection system. ELCWSD currently has a number of low
pressure sewer system within their system and has experienced problems with corrosion
requiring repairs to manholes and wet well structures plus the addition of odor control
equipment.
Comment 11: The first two paragraphs under the Treatment Plant Site Location
Alternatives section do not seem to relate to the subheading. Please amend as
appropriate.
0A

Response: The discussion of the proposed treatment system was duplicated in Section
3.3.2.3, Regional Wastewater Treatment System, and was deleted from the Treatment
Plant Site Location discussion.
Comment 12: Page eight states that the Middle Forney Creek WWTP does not have
adequate space for expansion of treatment facilities. However, on page seven it states
that the plant will be temporarily expanded to handle additional flows. Please clarify.
Response: The Middle Forney Creek WWTP has been upgraded from 0.75 to 0.975
MGD. The plant expansion proposed to serve the 20-year planning period would require
an upgrade to 4.0 MGD. Optimization and expansion of existing plant is discussed in
WKD Section 5.3.2, page 5-7. The 0.225 mgd expansion was accomplished by minor
plant modifications by retrofitting existing plant processes and increasing process design
loading. The Middle Forney Creek WWTP plant site is has housing developments on
three sides of the plant and the Middle Forney Creek, a railroad and new NC Highway
16 (4 lane divided highway) on the remaining side.
Comment 13: Page eight states, "With the proposed continued operation of the Middle
Forney Creek WWTP at 0.75 MGD (temporarily expanded to 0.975 MGD if approved),
the design for the new regional WWTP is 3.35 MGD". 1) When is the approval for this
facility expected? 2) Is there an alternate plan if the request is not approved?
Response: The "Authorization to Construct" for the Middle Forney Creek WWTP was
issued by NC DENR-DWQ on December 9, 2005. The Notice to Proceed was issued on
March 22, 2006, and the upgrade was completed in January 2007.
Comment 14: Have speculative limits been obtained for the new WWTP yet?
Response: Speculative limits were issued on March 18, 2004 by NC DENR DWQ, and
are included as Appendix B of WKD's Engineering Report.
Comment 15: Please state the elevations along the proposed collection system route and
at the proposed WWTP.
Response: The following description has been added to Section 4.1.1. of the EA. Based
on USGS contours, the elevation of the proposed sewer line corridor starts near 860 feet
above mean sea level at the northern (upslope) extent, and drops to about 700 feet at the
Forney Creek - NC 73 intersection, and about 680 feet near the Middle Forney Creek
WWTP. The elevation of the force main segment between the Middle Forney Creek
WWTP and Killian Creek climbs from the plant to about 800 feet, and down to 650 feet
near the (soon to be retired) Killian Creek pump station. The gravity line resumes again,
following the Killian Creek floodplain south to about 640 feet at the proposed treatment
plant. Elevations across the proposed treatment plant property range from 740 feet along
the western extent, down to 640 feet at the Killian Creek floodplain.

Comment 16: How much of the proposed roadside alignment is previously disturbed
land?
Response: Initially, the project will only include approximately 3,1001f of force main
along Little Egypt Road (previously disturbed road shoulder). From there, flows will
discharge into an existing line that flows down to Killian Creek. The remainder of
construction for the initial project will be along the Killian Creek floodplain. Future
construction north of the Middle Forney Creek WWTP will be gravity sewer interceptor
adjacent to Forney Creek and will not involve construction along roadsides.
Comment 17: Please clarify, including an explanation of how it will be determined
when directional drilling is not possible for a location.
Response: Directional drilling is generally more favorable for force mains or gravity
sewer lines installed with significant slope allowing for small grade variations. The
proposed application has very flat drainage basins and control of slope within borings
will be critical. The use of jack and bore under streams will be considered for crossings
of Killian and Forney Creeks during the design phase. Factors to be considered include
available access for bore pits, ground water elevations and the presence of rock. Bore pits
adjacent to stream crossing are often deep, involve groundwater issues and excavation
set -back requirements for excavation may do more environmental damage than open cut
stream crossings. Crossings of smaller tributaries are proposed to be open -cut due to
economic considerations and the minimal temporary impact to these streams.
Comment 18: Please discuss zoning along the proposed collection system, at the two
PUMP station sites, and at the proposed Killian Creek WWTP site.
Response: The Lincoln County zoning along the proposed interceptors, pump stations
and proposed WWTP site are listed as follows:
Interceptors
R-SF Residential — Single Family
R-T Transitional Residential
I-G General Industrial
Force Main (Little Egypt & Charlie Saine Road Area)
P-R Planned Residential
R-S Residential Suburban
Middle Forney Creek Pump Station
R-SF Residential — Single Family
Killian Creek WWTP, Pump Station & Force Main
I-G General Industrial
A brief description of these zoning categories is as follows:
• R-SF — traditional single family subdivisions that do not presently contain mobile
homes, duplexes or multi -family dwelling developments.
• R-S — residential type development where one or more public utilities are currently in
service or anticipated in the future.
4

• R-T — residential oriented uses in portions of County that have not experienced
significant growth and do not have public water and sewer facilities. These area are
considered to be development "holding zones" that may come under growth pressures
at some point in the future.
• I-G — general industrial uses for manufacturing, refining, processing, storage, and
assembly of goods. Most industrial related uses and a variety of industrial uses are
allowed.
• P-R — planned residential to accommodate development of residential communities
that incorporate a full range of housing types and limited commercial uses that
primarily serve the residents of the planned residential community.
Comment 19: Please address whether any local zoning or land use plans will need to be
changed following implementation of the proposed project.
Response: The Lincoln County zoning process routinely undergoes update
approximately every five (5) years. Rezoning of individual property is a common
occurrence and any property owner has the right to request rezoning. There are no
changes to the local zoning or land use plans anticipated to be needed to implement this
project.
Comment 20: Please address whether any areas of prime farmland soils will be directly
affected by the installation of the two new pump stations or at the proposed Killian Creek
WWTP.
Response: The following text was inserted into Section 4.2.1. of the EA. One pump
station will be installed at the existing Middle Forney Creek WWTP, and a second will be
installed at the Duke Power site. The Middle Forney Creek WWTP is developed, and
does not qualify for designation as prime farmland. The Killian Creek WWTP site
contains 26.4 acres of prime farmland soils (15.8 acres Cecil sandy loam; 0.95 acre
Chewacla (where protected from flooding); 2.3 acres Gaston sandy clay loam; 5.7 acres
Pacolet sandy clay loam; and 1.6 acres Riverview loam). The proposed footprint will
impact 5.2 acres of prime farmland soils. The Killian Creek Pump Station will be
installed in Cecil sandy loam, also a prime farmland soil. This pump station will result in
approximately 0.2 acre of prime farmland impacts.
Comment 21: Please address whether the installation of the two new pump stations will
impact floodplain areas.
Response: FEMA identified 100-year floodplains have recently been mapped to include
the areas near both proposed pump station sites. The new Killian Creek Pump Station
will be installed outside the mapped boundary. The new pump station located at the
Middle Forney Creek WWTP will be constructed within the 100-year floodplain within
the existing WWTP plant area. The elevation of the pump station and manholes at the
Middle Forney Creek WWTP will be designed at 2 feet above the 100 year flood
elevation. These structures are small and are not anticipated to have any significant
impact of the flood zone.

Comment 22: Page 13 states that negotiations are currently under way with Duke Power
to identify precise locations of the proposed pump station and force main to the new
WWTP property. 1) When will these negotiations be complete so fieldwork can
continue? 2) There is some confusion in the text about the number of pump stations
included. Please clarify.
Response: The County approved the purchase of the 38 acre WWTP site from Duke
Energy on April 19 at a cost of $275,000. Boundary surveys were conducted in May
2006. The pump station, force main and gravity sewer easement are being negotiated
separately and have not been completed at this date.
There are two new pump stations included in the proposed project; one located at the
existing Middle Forney Creek WWTP, and the second located on the Duke Energy site
near the proposed new Killian Creek WWTP. The engineering report has been revised to
provide a map of the proposed project in Section 6, Figure 6.2.
Comment 23: Please indicate whether the entire service area receives water from the
County system, private wells, or both.
Response: The majority of service area receives water from ELCWSD with water from
the Lincoln County Lake Norman WTP with some individual private wells still utilized.
Comment 24: Please state the source of potable water for those served by the proposed
project.
Response: The Lincoln County Lake Norman water treatment plant provides potable
water for the majority of those served by the project. There are 30 to 40 current sewer
customers that remain on private wells. The Lake Norman water treatment plant is
currently being upgraded to meet the area demand for water capacity.
Comment 25: Please clarify exactly how many acres will be cleared at the new WWTP
site.
Response: The new WWTP property purchased from Duke power is 38.049 acres, of
which 20 will be cleared for construction of the proposed Killian Creek WWTP.
Comment 26: Page 20 references section 4.8.4.3., which does not exist. Please revise.
Response: The reference should have read, Section 4.8.5. The error has been corrected.
Comment 27: How will the operation of the proposed WWTP impact local fish and
aquatic habitats?
Response: Mitigation measures to protect are discussed in Section 4.9.2 of the
document. Lincoln County has also recently, as a result of negotiations with regulatory
0

resource agencies, adopted an Erosion and Sedimentation Control Ordinance, and is
presenting a Streamside Buffer Ordinance to County Commissioners on 2 April 2007.
Both ordinances are attached in Appendix C.
Comment 28: Please address whether there are surrounding areas of similar habitats to
accommodate the relocation of displaced wildlife.
Response: Of the 38.049 acre parcel purchased by ELCWSD, only 53 % (20 acres) will
be cleared to accommodate the new facility. The remainder of the tract will be retained
in its current, vegetated condition and will serve as refuge for wildlife displaced by
construction of the project as proposed. The Duke Power property adjoining the new
WWTP site on all sides (Lincoln County PIN 3691-49-6398) is 677.74 acres. The
majority of this property (73%) is maintained in a forested state (50 % hardwood forest,
23 % pine plantation), and the remainder is developed / lawn (including extensive
periodically mowed rights -of -way) (25%) and open water (2%). There are sufficient
habitats adjacent to the WWTP site to accommodate displaced wildlife.
North of NC 73, nearly the entire length of new corridor is bounded on the east by the
Seaboard Coast Line Railroad, prohibiting encroachment toward the new 40-foot right-
of-way from the east. Additionally, the FEMA floodplain mapped up Forney Creek
from NC 73 ranges in width from 800 to 120 feet wide (including both floodplains), and
is proposed for protection under a new Lincoln County Streamside Buffer Ordinance to
be introduced on April 2. Although applicable to floodplains across the entire county,
this new regulation would preserve adjacent lands to serve as refuge for wildlife
displaced by construction of the new corridor.
Comment 29: Page 23 states that surveys for protected species north of NC 73 are
pending at this time and will be completed prior to construction. These surveys need to
be completed and any impacts included in the EA so they can be covered in the FNSI
issued for the project.
Response: Surveys for Dwarf -flowered heartleaf were conducted along environmentally
preferred alignments between 17 and 22 May, 2006 and none were found. Suitable
habitat for the species does exist along project alignments north of NC 73, and on the
Killian Creek WWTP property, but the species was lacking. Surveys for Georgia aster
were not conducted north of NC 73 because of lack of suitable habitat. Gravity sewerline
alignments follow the Forney Creek floodplain over the entire length. Where suitable
canopy openings were located, the landscape was too wet to support this species. Both
species could occur in the project service area, but will not be directly impacted by
construction of the project as proposed.
Comment 30: Please determine if any water bodies contribute to the Six -mile Creek
watershed in South Carolina where populations of the Carolina heelsplitter have been
found. Additional mitigation may be necessary to address water quality concerns
downstream.
7

Response: Six -mile Creek flows from east to west, south of Charlotte, into the Catawba
River. No portion of any stream in Lincoln County drains to the Six -mile Creek
watershed in South Carolina.
Comment 31: Please discuss any previous odor problems or complaints due to public
wastewater infrastructure in the proposed service area.
Response: ELCWSD has received several recent odor complaints associated with the
Middle Forney Creek WWTP and has ongoing efforts to determine the source of the
odors. Odor complaints have also been received in the area where low pressure sewer
systems connect into gravity sewers and downstream pump stations. ELCWSD has
recently installed two (2) odor scrubber systems and has four (4) additional system on
order for pump stations. ELCWSD now requires all new developer installed pump
stations to include odor control system.
Comment 32: Please provide the lengths of line segments included in Figure 1.0.
Response: Figure 5.1 in WK Dickson's engineering report:
Section K-12 - 9,100 feet of 24-inch gravity sewer
Section K-13 - 9,400 feet of 24-inch gravity sewer
Section K-14 - 2,000 feet of 24-inch gravity sewer
Section K-15 - 9,000 feet of 18-inch gravity sewer
Section K-141 - 4,700 feet of 8-inch gravity sewer
Comment 33: Please provide the capacities of the two new pumping stations in Figure
1.0.
Response: Proposed pump station capacities are:
1) Proposed Pump Station to Killian Creek Gravity Sewer at Middle Forney Creek
• Design flow - 1.0 mgd ADF (700 gpm)
• Duplex Pumps - 1,750 gpm @ 170' TDH
2) Proposed Phase I WWTP Influent Pump Station on Killian Creek
• Design flow - 1.68 mgd ADF (1,167 gpm)
• Duplex Pumps — 2900 gpm @ 105' TDH with space for two (2) additional pumps
3) Proposed Phase II WWTP Influent Pump Station on Killian Creek
• Design flow — 3.35 mgd ADF (2326 gpm)
• Triplex Pumps — 2900 gpm @ 105' TDH with space for one (1) future pump

Comments Provided 11 April 2006

Comment 1: The federally threatened dwarf -flowered heartleaf and Georgia aster have
been found close to the project area. The EA states that surveys for these species will be
completed prior to construction of lines north of NC 73. We cannot concur with a FNSI
for the proposed project until those surveys are complete.
Response: Surveys for Dwarf -flowered heartleaf were conducted along environmentally
preferred alignments between 17 and 22 May, 2006 and none were found. Suitable
habitat for the species does exist along project alignments north of NC 73, and on the
Killian Creek WWTP property, but the species was lacking. Surveys for Georgia aster
were not conducted north of NC 73 because of lack of suitable habitat. Gravity sewerline
alignments follow the Forney Creek floodplain over the entire length. Where suitable
canopy openings were located, the landscape was too wet to support this species. Both
species could occur in the project service area, but will not be directly impacted by
construction of the project as proposed.
Comment 2: Although we are pleased the County has adopted ordinances aimed at
protecting fish and wildlife resources, we do not believe the existing ordinances will
adequately protect the aquatic ecosystem or compensate for the indirect or cumulative
impacts associated with this project. Adoption of ordinances to protect forested riparian
corridors and 100-year floodplains, and stormwater control requirements is essential to
protect water quality and aquatic habitats.
Response: In response to these concerns, echoed during our 18 August 2006 conference
call (minutes attached in Appendix A), Lincoln County has adopted a Soil Erosion and
Sedimentation Control Ordinance, to become effective 1 May, 2007, and has completed a
draft Streamside Buffer Ordinance to be presented to the County Board of
Commissioners on 2 April 2007 (the text of both ordinances are included in Appendix Q.
The Erosion Control Ordinance (Adopted Tuesday, 23 January 2007; effective 01 May
2007) states that all land disturbing activities one acre or more must have an approved
plan, prior to disturbance. Activities impacting less than one acre, but requiring a
building permit, require completion of an application. The ordinance requires identifying
areas both on- and off -site that are vulnerable to damage from sedimentation and
stormwater flows. All visible siltation must be confined to the outer 25 % of mandatory
buffer areas around surface waters. Plans must be submitted at least 30 days prior to any
construction activity. At least 48 hours prior to commencing those activities, the Erosion
Control Specialist must be notified to schedule a pre -construction conference to go over
the plans, discuss what is expected of the project and expected performance. It requires
inspection of all erosion control structures weekly, and within 24 hours of a half -inch rain
event over a 24-hour period, and that has to go on for a six-month period. Corrective
actions and maintenance identified during those inspections shall commence
immediately. The design storm for these structures is a 10-year storm event. During
construction, the developer is responsible for upkeep, and after construction, the
landowner is responsible. The maximum non -erosive velocities for the 10-year storm are
defined by soil type of the receiving stream or floodplain. In HQW, a maximum 20 acres
disturbance, at any one time, everywhere it is requested that developers limit disturbance
0

areas to 20 acres. The settling efficiency should be 70 % of the 40 micron particle size,
and no activities that are out of compliance with State and Federal laws will be allowed.
Changes made to the 26 July 06 proposed Draft Erosion and Sedimentation Control
Ordinance, resulting directly from multi -agency conference call discussions include:
1) Addition of 'Best Management Practices' definition in Section 3, Definition f.
2) Addition of 'native, or non-invasive' species to be used for ground cover added to
Section 3, Definition x.
3) Addition of 'Intermittent' streams to the definition of Jurisdictional waters, Section 3,
Definition aa.
4) Addition of 'Division of Water Quality' as defining 'wetlands', Section 3, Defmition
bbb.
5) Additional requirement of one member of the newly formed Lincoln County
Environmental Review Board to be a Professional Environmental Biologist.
The buffer overlay district applies to perennial and intermittent streams. The ordinance
provides protection to the 100-year floodplain as identified by FEMA, within which no
clearing can occur, or mandatory 50-foot wide riparian buffers along perennial and
intermittent streams. Streams will be identified by their presence on the most recent
USGS topographic mapping, or as determined by Lincoln County. It also requires
delineated buffers on all plans submitted for construction. The ordinance applies to all
lands in the County's jurisdiction.
Comment 3: NCWRC's guidance document recommends 100-foot buffers on perennial
streams, and 50-foot buffers on intermittent streams. Also, sewerlines should not be
located in these buffers, and should be constructed of materials equal in durability to
ductile iron.
Response: Please see the response to USFWS Comment 2, above, for a discussion of
riparian buffer protections proposed by the County.
Comment 4: We recommend that a plan for the control and treatment of stormwater,
adequate to avoid any changes to the hydrology of streams in the project area, be
implemented for each development that occurs as a result of the new sewer system. We
encourage the use of Low Impact Development technologies.
Response: Please see the response to USFWS Comment 2, above, for a discussion of
Stormwater control regulations recently adopted by the County.
Comment 5: We recommend that no new development that will utilize this project be
allowed in 100-year floodplains.
Response: The streamside buffer regulations proposed by the County, discussed in
response to Comment 2 above, would prohibit any clearing in the 100-year floodplain,
unless waived by the Zoning Administrator.
10

Comment 6: Measures to control erosion and sedimentation should be incorporated into
project plans. Native, annual small grains should be planted immediately after
construction to help avoid erosion. No fertilizers or pesticides should be used near
streams.
Response: Please see the response to USFWS Comment 2, above, for a discussion of
Stormwater control regulations recently adopted by the County. As requested by Ms.
Angie Rogers (NC NHP) during our 18 August 2006 conference call, a stipulation to use
only native plant materials was incorporated into the ordinance prior to adoption.
Comment 7: Where feasible, woody debris should be piled along the edges of
construction corridors to improve wildlife habitat. Mowing of the corridor should be
prohibited between April 1 and October 1 every year, and only one third of the length
should be mowed in a given year.
Response: The requirement for woody debris along edge of construction corridors will
be added to the construction requirements but will be subject to property owner
acceptance during right-of-way easement negotiations. The requested mowing restriction
after completion of construction is not considered practical as the County must maintain
access to the sewer right of way to inspect and maintain the lines.
Comment 8: We strongly encourage consideration of UV disinfection at the new Killian
Creek WWTP, and alternative disposal methods (land application, industrial cooling
water, etc).
Response: As described in the EA, UV disinfection is proposed as the means of
disinfection at the new Killian Creek WWTP. Alternative disposal methods are planned
for constant review. Although currently there are no feasible options, Duke Power has
agreed to review effluent water quality of the final plant to determine if the water is up to
their standards for reuse water quality. As the service area develops, additional areas will
likely become available to pursue land application of treated wastewater.
Comment 9: To minimize impacts to aquatic resources, we encourage the use of pump
station and force main systems, rather than gravity collection systems.
Response: Pump stations and force mains were considered within the alternatives
presented within the engineering report. The conveyance system alternative elected to
utilize a pump station and force main to pump flow from the Middle Forney Creek
collection system to the Killian Creek collection system. This alternative further utilized
an existing force main currently pumping Killian Creek flow to the Middle Forney Creek
WWTP. By reversing the flow within this force main, significant force main
construction was avoided. This pumping/force main alternative avoided the construction
of a gravity sewer extending from the Middle Forney Creek WWTP down to Killian
Creek in areas identified with significant wetland areas. The proposed Killian Creek
WWTP influent pump station was also relocated up stream on Killian Creek, remote from
11

the WWTP site with a force main utilized for conveyance to the WWTP site. The force
main routing is proposed to follow existing Duke Energy power line to further minimize
environmental impacts.
Replacement of the proposed gravity interceptors within the upper Forney Creek area is
not a desired alternative. This would require complete replacement of existing force
mains that are fast approaching design capacity. The replacement work would require
construction within heavily development commercial corridors disruptive to area traffic
areas and adding considerable project costs. The proposed gravity interceptors in this
area are intended to serve developing areas with multiple connection points allowing the
elimination of existing pump stations approaching design capacity. The proposed gravity
interceptors will improve overall system reliability and reduce the ongoing maintenance
and operation requirements associated with the pump stations and emergency power
generator systems.
Comment 10: We would like to review an analysis, including a description and the
acreage, of all wetlands that will be converted from forested to herb/scrub wetlands, and
we recommend that a compensatory mitigation plan be completed for the loss of wetland
function and value.
Response: Descriptions, acreages / lengths, and mitigation proposals for impacts to
aquatic resources are compiled for review and approval by the US Army Corps of
Engineers, and NC Division of Water Quality. Because of the relatively short window of
approval (24-months) for those permits, and the requirement of the State and Federal
agencies that regulate those impacts that a FNSI be issued on the EA before applying for
those permits, and unforeseen changes that will occur as a result of these reviews, we are
unable to comply at this time. If the US Fish and Wildlife Service would like to receive a
copy of the Clean Water Act Section 404/401 permit application when it is submitted,
please advise and we will instruct the project engineers to copy your office on that
submittal.
Comment 11: We would like to see a map showing where streams will be trench cut,
where directional drilling or aerial conveyance cannot be accomplished at stream
crossings. We also recommend development of a stream bank monitoring and
maintenance program to promptly stabilize stream banks near the line crossings
throughout the life of this project.
Response: Stream crossings 1, 9, 17, 18, 24, and 27 on Figure set 5 (crossings of the
main stem of Forney and Killian creeks) are being considered for directional drilling,
based on conversations with project engineers. The remainder of stream crossings will be
accomplished by open trench cut, and all construction will be in accordance with
approved Clean Water Act permits. Stream bank monitoring, maintenance, and
stabilization will be addressed with State and Federal agencies tasked with managing
those impacts. No federally protected flora or fauna are known to occur in these
12

drainages, and no impacts to federally protected species are expected to occur from this
construction.
Comment 12: Executive Order 11988 requires federal agencies (or their designated
representatives) to consider and protect floodplain functions. Any development that will
impact floodplains will need to be assessed.
Response: Construction of the collection system will be largely within FEMA 100-year
floodplains. Manholes will be elevated, or sealed with their vents elevated, above the
100-year flood elevation to prevent inflow during storm events. The streamside buffer
regulations proposed by the County (discussed in response to Comment 2 above), would
prohibit any clearing in the 100-year floodplain, unless waived by the Zoning
Administrator.
Comment 13: We would like to see details of all surveys and assessments, including
acreage and descriptions of all wetlands to be filled or impacted, including streams (with
Rosgen classification) and description of biotic resources. Any wetlands impacted by the
proposed project should be mapped in accordance with the, "Federal Manual for
Identifying and Delineating Jurisdictional Wetlands".
Response: Jurisdictional wetlands were delineated using the USACE Wetlands Delineation
Manual (Environmental Laboratory, 1987) and the most recent supplementary technical
literature for hydrophytic vegetation, hydric soils, and hydrology indicators. Jurisdictional
surface waters were identified using USACE and NCDWQ field indicators, as required by
the federal and state agencies that regulate impacts to these resources. They are described in
Section 4.6, and their biotic resources are discussed in Section 4.10. Rosgen classifications
are not universally accepted, and they are not addressed in the EA document. However, we
do record and report all pertinent aspects of Rosgen's classification system applicable to, and
specifically for, US Fish and Wildlife review. These include stream permanence, width,
bank vegetation/habitats, and stream substratum at each individual proposed stream
crossing. This information is included in Table 3, with streams numbered as they are
illustrated in Figure set 5.
The project design has not been finalized, and re -alignments north of NC-73 may occur as
the project moves forward. Specific direct impacts will be reviewed individually by the US
Army Corps of Engineers and NC Division of Water Quality during the permitting process.
As mentioned in the USFWS reference manual, in the Section 1.4. discussion of the Clean
Water Act permit application process, "Under authority of the Fish and Wildlife
Coordination Act, the FWS ... review(s) applications for these federal permits and provides
comments to the CE on the environmental impacts of the proposed work". Project owners
respectfully request that these concerns be addressed by the US Fish and Wildlife during
that window of opportunity, as the Environmental Assessment is not a permitting tool, and
issuance of a FNSI will not result in approvals for specific project related impacts.
13

Comment 14: We would like to see a description of the fishery and wildlife resources
within existing and required rights -of -way, new borrow areas, and any other areas to be
impacted during construction of the project.
Response: The requested discussions are included in Section 4.9, "Fish and Aquatic
Habitats", and Section 4.10, "Forests and Wildlife Habitats".
Comment 15: We would like to see an assessment of all expected secondary and
cumulative environmental impacts associated with the proposed work. Include extent
and type of development, how growth will be maintained with regard to sewer lines,
water lines, parking, roads, etc.
Response: Specific discussions quantifying extents and types of developments and
impacts are not possible to compile. However, all expected S & C impacts are discussed
throughout the document in mitigation sections following each resource discussion. The
Erosion and Sedimentation Control Ordinance, recently adopted, and Streamside Buffer
Regulations proposed for adoption (Appendix C) will further mitigate for impacts
associated with future build -out.
Comment 16: The loss, degradation, or fragmentation of wildlife habitats as a result of
this project, including acreages, locations, and cover types for both construction and
secondary and cumulative impacts should be discussed.
Response: As discussed above, specific impact discussions are not possible at this time.
However, in anticipation of population growth and development expansions throughout
the project area, Lincoln County has drafted two ordinances addressing protection of
floodplains and forested riparian buffers, and erosion and sedimentation controls (one
adopted thus far, the second up for review by County Commissioners on 02 April 2007).
Please see our response to USFWS Comment #2 above for detailed descriptions.
Comment 17: We would like to see any new mitigative measures that will be employed
to offset habitat value losses associated with any phase of this project.
Response: Please see our response to Comment 16 above, and Comment 2 above for
detailed descriptions of mitigation proposed to offset these potential impacts.

Comment: We recommend that impacts to Section 404 jurisdictional waters be avoided
completely by directional drilling or aerial crossings, or that minimization of impacts be
achieved. If any impacts cannot be avoided, permitting will be required. We anticipate
NWP 12 can be utilized for this project.
Response: Project designs north of NC 73 have not been finalized to date. RJG&A did
walk the entire length of this floodplain, and provided project engineers with
'environmentally preferred alignments' that minimize impacts to these resources. All
essential stream crossings were proposed at perpendicular angles (75-105 degrees), and
edges of floodplains were suggested where environmentally sound. Exceptions to this
blanket recommendation by resource agencies include hillside seeps and vernal pools that
provide essential amphibian breeding habitats, free of predatory fish, that are not
provided elsewhere on the floodplain. Crossings of stream channels were suggested
where: A) the impact of crossing a tributary is less than that of crossing the main stem; B)
avoidance of riparian wetlands outweighed the significance of avoiding directionally
drilled stream crossings, and C) where the resource to be crossed was of less
environmental value than that to be avoided (e.g. adjacent riparian wetlands or stream
crossings).
Assuming the environmentally preferred alignments are followed, wetland impacts have
been minimized to below NWP 12 thresholds, but stream crossings may push the project
to an individual permit. Crossings of the main stems of Killian's and Forney creeks will
be directionally drilled. These include stream crossings 1, 9, 17, 18, 24, and 27 depicted
in Figure set 5. The remaining 21 crossings (identified based on environmentally
preferred alignments) are proposed for open -trench cutting and will need to be negotiated
with project design engineers at the time of Section 404/401 permitting.

Comments Provided 12 April 2006
Comment: There is a high probability for archaeological sites in the project area. We
recommend that a comprehensive archaeological survey be conducted to identify and
evaluate the significance of any archaeological remains that may be impacted by the
proposed project.
Response: Project owners initiated archaeological investigations along 'environmentally
preferred alignments' based on SHPO's request. At the northern extent of the Forney
15

Creek collection lines, unidentified bone fragments were found and caused concern for
project alignments. However, later investigations found that these were in fact animal
remains, and the archaeologist's final report was submitted to NC SHPO for approval in
September 2006, and recommended that cultural resource clearance be granted. No
significant archaeological resources were identified along recommended project
alignments. No impacts to these resources are expected to result from construction of the
project as proposed along recommended alignments.

State Clearinghouse Project Number 1343
Comments Provided 03 April 2006
Comment 1: The concerns identified in our guidance memorandum available at
http://www.ncwildlife.org/pg07_WildlifeSpeciesCon/pg7c3_impacts.pdf should be
addressed fully for all watersheds within the current and future MSAs.
Response: Project owners and their consulting engineers have been advised of this
recommendation, and provided with a bulleted summary of the recommendations
provided therein. Negotiations with US Fish and Wildlife Service and NC Wildlife
Resources Commission staff during development of this project resulted in the creation of
two new development ordinances (discussed in USFWS Comment #2 above) geared
toward protection of 100-year floodplains and forested riparian buffers and erosion and
sedimentation concerns.
Comment 2: Prior to site clearing activities, all jurisdictional wetland and stream
features should be delineated by an environmental professional prior to issuance of
planning and zoning approvals. Unless a part of ongoing and continuing land use,
agricultural and silvicultural exemptions should not be permitted.
Response: Section 404 and 401 of the Clean Water Act require these investigations for
any project with the potential to impact these resources. When plans are submitted to the
Building and Land Development Office for permitting, they are passed on to the USDA
Soil Conservation Service for comment. A qualified soils professional inspects the site to
determine the presence of wetland areas and need for permitting under Section 404 and
401 of the Clean Water Act. No building permit is issued until the project has addressed
these issues.
Comment 3: Riparian buffers 50-foot wide should be maintained on all sides of
intermittent, and 100-foot buffers should be maintained on all sides of perennial, stream,
wetland, and erodible areas. These widths should be doubled in watersheds known to
contain federally protected species. Public utilities should be kept out of the buffers, and
located along the floodway fringe wherever possible.
9-i-

Response: A new ordinance proposed for adoption has been prepared by Lincoln
County to require 50 foot buffers (30 feet wooded and 20 foot vegetated) on all perennial
streams identified on USGS topographic mapping, or as determined by Lincoln County.
Exemptions for public utilities within these buffers will be allowed at the Lincoln County
Zoning Administrator's discretion. There are no known federally protected species in
these areas, based on NC Natural Heritage Program's online database for Lincoln County.
Comment 4: Bridges are recommended for all stream, floodplain, and associated wetland
crossings. If culverts are used, 48 inch and larger barrels should be buried one foot below
the stream channel, and barrels less than 48 inches should be buried at least 20 % of their
diameter deep, based on thalweg depth, to allow for the passage of aquatic animals. If
multiple barrels are needed, base flow barrels should be installed at the bank -full bench
elevation to allow for the passage of high flow events.
Response: The construction of this project does not require culverts. All crossings of
these resources will be directionally drilled or open trench cut within the requirements of
Section 404 / 401 permits. Regulation of these impacts beyond project construction will
be in accordance with the discussion in Section 5.2 of the EA or applicable North
Carolina minimum standards.
Comment 5: Stormwater management should be required to maintain pre -development
hydrographic conditions. Stormwater control measures should be required before
impervious surface areas reach 10 % % in most watersheds, and 6 % in watersheds
known to contain federally protected species. Low Impact Development techniques,
described at www.lowimpactdevelopment.org, are encouraged for all new developments
and redevelopment efforts.
Response: In response to these concerns, echoed during our 18 August 2006 conference
call (minutes attached in Appendix A), Lincoln County has adopted a Soil Erosion and
Sedimentation Control Ordinance, to become effective 1 May, 2007.
The Erosion Control Ordinance (Adopted Tuesday, 23 January 2007; effective 01 May
2007) states that all land disturbing activities one acre or more must have an approved
plan, prior to disturbance. Activities impacting less than one acre, but requiring a
building permit, require a completed application. The ordinance requires identifying areas
both on- and off -site that are vulnerable to damage from sedimentation and stormwater
flows. All visible siltation must be confined to the outer 25 % of mandatory buffer areas
around surface waters. Plans must be submitted at least 30 days prior to any construction
activity. At least 48 hours prior to commencing those activities, the Erosion Control
Specialist must be notified to schedule a pre -construction conference to go over the plans,
discuss what is expected of the project and expected performance. It requires inspection
of all erosion control structures weekly, and within 24 hours of a half -inch rain event over
a 24-hour period, and that has to go on for a six-month period. Corrective actions and
maintenance that are identified during those inspections shall commence immediately.
The design storm for these structures is a 10-year storm event. During construction, the
developer is responsible for upkeep, and after construction, the landowner is responsible.
17

The maximum non -erosive velocities for the 10-year storm are defined by soil type of the
receiving stream or floodplain. In HQW, a maximum 20 acres disturbance at any one
time, everywhere it is requested that developers limit disturbance areas to 20 acres. The
settling efficiency should be 70 % of the 40 micron particle size, and no activities that are
out of compliance with State and Federal laws will be allowed.
Changes made to the 26 July 06 proposed Draft Erosion and Sedimentation Control
Ordinance, resulting directly from multi -agency conference call discussions include:
1) Addition of 'Best Management Practices' definition in Section 3, Definition f.
2) Addition of 'native, or non-invasive' species to be used for ground cover added to
Section 3, Definition x.
3) Addition of 'Intermittent' streams to the definition of Jurisdictional waters, Section 3,
Definition aa.
4) Addition of'Division of Water Quality' as defining 'wetlands', Section 3, Definition
bbb.
5) Additional requirement of one member, of the newly formed Lincoln County
Environmental Review Board, to be a Professional Environmental Biologist.
Comment 6: Fill in FEMA floodplains and jurisdictional water floodplains should be
avoided, and no net loss strategies implemented.
Response: As proposed in Lincoln County's draft Streamside Buffer Ordinance, scheduled
to be presented to the Lincoln County Board of Commissioners on 02 April 2007, the entire
width of all FEMA mapped 100-year floodplains will be protected from future clearing and
development. Where no practical alternative exists (e.g., road crossings, water dependent
structures, etc.), waivers can be granted by the Lincoln County Zoning Administrator.
Comment 7: Sediment and erosion controls should meet or exceed existing standards, and
preferably meet design standards for sensitive watersheds (15A NCAC 4B .0124).
Response: See response to Comment 5, above.
Comment 8: About half of the streams in the service area are proposed to have
protective buffer requirements due to their presence on USGS mapping. These maps
should not be used because they greatly underestimate the actual extent of streams in the
project service area.
Response: The current Lincoln County Streamside Buffer Ordinance was developed by
a committee and received first reading in the April 2, 2007 meeting of the County
Council with the final vote scheduled for the April 15, 2007 Council meeting. The
ordinance is anticipated to become effective May 1, 2007. The forgoing concerns have
been brought to the committee's attention and will be considered as changes requiring an
amendment to the Ordinance.
18

Comment 9: We recommend avoiding chlorine and de -chlorination chemicals, and
using UV or ozone treatment instead. Wastewater reuse options should be continuously
evaluated, particularly when golf courses or large park lands become available for such
uses.
Response: As described in the EA, UV disinfection is proposed as the means of
disinfection at the new Killian Creek WWTP. Alternative disposal methods are planned
for constant review. Although currently there are no opportunities, Duke Power has
agreed to review effluent water quality of the new plant to determine if the effluent is up
to their standards for reuse. As the service area develops, additional areas will likely
become available to pursue land application of treated wastewater.
Comment 10: The document should include a description of fisheries and wildlife
resources in the project area, including a list of all protected species and any areas that
may be impacted by secondary and cumulative impacts within each sub -basin.
Response: The requested discussion of fisheries and wildlife resources in the project
area are included in Section 4.9, "Fish and Aquatic Resource" and Section 4.10, "Forests
and Wildlife Habitats". Summaries of expected secondary and cumulative impacts are
included in mitigation discussions following those sections.
Comment 11: Please include a description of all wetlands and waters that will be
affected by the project.
Response: Wetlands to be impacted by project construction are listed in Table 4 by
temporary and permanent impact acreage, and habitat type (ALH = Alluvial Hardwood
Forest, and MMH = Mature Mesic Hardwood Forest). All other potential wetland
impacts were avoided by RJG&A's recommended, 'environmentally preferred alignment'.
Comment 12: Please provide mapping of all streams and wetlands in the area.
Response: The requested mapping is provided in Figure set 5.
Comment 13: Please provide a description of any activities that will be carried out in
streams and wetlands. Include square feet of wetland impacts, and linear feet of stream
impacts.
Response: Activities to be carried out in streams and wetlands during construction of the
project will be in accordance with specific and general nationwide permit conditions
dictated by the US Army Corps of Engineers, and NC Division of Water Quality.
Briefly, these activities will include non -mechanized clearing of vegetation, excavation
and stockpiling of wetland soils outside jurisdictional areas, installation of utility lines,
backfilling with native topsoil, and removal of excess soils to upland areas. All
requirements of both general and nationwide permit conditions will be met at all times
during construction, in accordance with approved Clean Water Act permits.
19

Anticipated square feet of wetland impacts and linear feet of stream impacts are listed in
Tables 4 and 3 of the EA, respectively.
Comment 14: Include a description of the project site and non -wetland natural
communities.
Response: The requested descriptions in project site areas are included in section 4.10,
"Forests and Wildlife Habitats", and Appendix B has been added to include these
discussions of non -project portions of the service area.
Comment 15: Provide a description of all upland wildlife habitat that will be impacted
by the proposed project.
Response: Upland wildlife habitat that will be directly impacted by the proposed project
are discussed in Section 4.10. Appendix B has been added to the EA to provide
descriptions of upland wildlife habitats that may be impacted by secondary and
cumulative impacts of the proposed project.
Comment 16: Please provide a project map that includes land cover type and acreage to
be impacted.
Response: Table 5 and Figure set 6 contain the requested information.
Comment 17: Discus the extent to which the project will result in loss or degradation of
habitats.
Response: The gravity sewer lines and force main will be installed in many locations by
open trench construction and in others by directional boring. Each system component is
being designed fully consistent with the U.S. Army Corps of Engineer's Nationwide
Permit 12. A DENR-approved Erosion and Sedimentation Control Plan incorporating
appropriate construction BMPs will be followed to minimize soil loss and water quality
impacts during construction. The permanently maintained (mowed) access corridors
along off -road segments will be typically 20 feet wide, except in wetlands where
permanent mowing is limited to 10 feet wide in accordance with DWQ General
Certification 3374. Most non -forest uses of the roadside and off -road sewer line corridors
will not be permanently affected following sewer installation, including lawns, gardening,
pasture, crops, recreation, and pavement. No buildings or permanent structures will be
allowed within the sewer line rights -of -way.
Comment 18: Please discuss any measures to be employed to mitigate for unavoidable
habitat losses.
Response: In response to these concerns, echoed during our 18 August 2006 conference
call (minutes attached in Appendix A), Lincoln County has adopted a Soil Erosion and
Sedimentation Control Ordinance, to become effective 1 May, 2007, and has completed a
20

draft Streamside Buffer Ordinance to be presented to the County Board of
Commissioners on 2 April 2007 (the text of both ordinances are included in Appendix Q.
The Erosion Control Ordinance (Adopted Tuesday, 23 January 2007; effective 01 May
2007) states that all land disturbing activities one acre or more must have an approved
plan, prior to disturbance. Those activities impacting less than one acre, but requiring a
building permit, require a completed application. The ordinance requires identifying
areas both on and off -site that are vulnerable to damage from sedimentation and
stormwater flows. All visible siltation must be confined to the outer 25 % of mandatory
buffer areas around surface waters. Plans must be submitted at least 30 days prior to any
construction activity. At least 48 hours prior to commencing those activities, the Erosion
Control Specialist must be notified to schedule a pre -construction conference to go over
the plans, discuss what is expected of the project and expected performance. It requires
inspection of all erosion control structures weekly, and within 24 hours of a half -inch rain
event over a 24-hour period, and that has to go on for a six-month period. Corrective
actions and maintenance that are identified during those inspections shall commence
immediately. The design storm for these structures is a 10-year storm event. During
construction, the developer is responsible for upkeep, and after construction, the
landowner is responsible. The maximum non -erosive velocities for the 10-year storm are
defined by soil type of the receiving stream or floodplain. In HQW, a maximum 20 acres
disturbance at any one time, everywhere it is requested that developers limit disturbance
areas to 20 acres. The settling efficiency should be 70 % of the 40 micron particle size,
and no activities that are out of compliance with State and Federal laws will be allowed.
Changes made to the 26 July 06 proposed Draft Erosion and Sedimentation Control
Ordinance, resulting directly from multi -agency conference call discussions include:
1) Addition of'Best Management Practices' definition in Section 3, Definition f.
2) Addition of 'native, or non-invasive' species to be used for ground cover added to
Section 3, Definition x.
3) Addition of 'Intermittent' streams to the definition of Jurisdictional waters, Section 3,
Definition aa.
4) Addition of'Division of Water Quality' as defining 'wetlands', Section 3, Definition
bbb.
5) Additional requirement of one member, of the newly formed Lincoln County
Environmental Review Board, to be a Professional Environmental Biologist.
The buffer overlay district applies to perennial and intermittent streams. The ordinance
provides protection to the 100-year floodplain as identified by FEMA, within which no
clearing can occur, or mandatory 50-foot wide riparian buffers along perennial and
intermittent streams, whichever is greater. Streams will be identified by their presence on
the most recent USGS topographic mapping, or as determined by Lincoln County. It also
requires delineated buffers on all plans submitted for construction. The ordinance applies
to all lands in the County's jurisdiction.
21

Comment 19: Please discuss the secondary and cumulative impacts of development
supported by the proposed project.
Response: Construction of new sewer lines and treatment capacity will induce
population growth, leading to residential and commercial construction through the
projected planning timeline as described in the PER. Proposed growth in the service area
will result in an unknown quantity and rate of land clearing commensurate with this
growth. Progressive conversion of forested and agricultural land to urban and suburban
uses will affect local forestry and agricultural production, scenic and recreational uses,
historic and pre -historic resources, fish and wildlife populations, streams and flood
plains, wetlands, water quality, air quality, and other resources discussed in the EA.
Similar land use trends are ongoing in adjacent counties, including Gaston, Mecklenburg,
Iredell, and Catawba counties, resulting in cumulative impacts not attributable to the
Lincoln County project. The Charlotte -Gastonia -Rock Hill Metropolitan Statistical Area
(MSA), which includes five NC counties (south of Lincoln County) plus York County,
SC grew from 1,024,096 people in 1990 to 1,330,448 people in 2000, and continues to
add about 35,000 people per year.
Comment 20: Include a discussion of how stormwater will be collected and treated at
the source. Include residential and industrial development BMPs that will be required.
Response: The response to Comment 18 above details the County's new Erosion and
Sedimentation Control regulations. The ordinance is included in Appendix C of the EA.
Comment 21: Include specific measures to protect stream corridors, and a minimum of
the 100-year floodplain.
Response: The response to Comment 18 above details the County's proposed Streamside
Buffer Regulations, due to be presented for adoption on 02 April 2007, and an anticipated
effective date of 01 May, 2007. The rules require protection of the entire 100-year
floodplain, or 50-foot riparian buffers on USGS-mapped intermittent and perennial
streams, whichever is greater.
Comment 22: How will water conservation and wastewater reuse strategies be
addressed in the future?
Response: Alternative disposal methods are planned for constant review. Although,
currently there are no opportunities, Duke Power has agreed to review effluent quality of
the finished plant to determine if the water is up to their standards for reuse. As the
service area develops, additional areas will likely become available to pursue land
application of treated wastewater.
Comment 23: Include a discussion of any local ordinances that will mitigate for
secondary and cumulative impacts.
22

Response: In addition to the local ordinances described in Section 5.2 of the EA, our
response to Comment 18 above details two new ordinances (one adopted, one due to be
reviewed on 02 April 2007) the County has developed in response to these environmental
concerns.
Comment 24: Discuss the use of mitigation, preservation, deed restrictions,
conservation and management plans, including detailed site descriptions and
identification of the entity that will be charged with management of these areas.
Response: See our response to Comment 23 above.
Comment 25: Construction corridors should be the minimum width necessary for
construction, and should not exceed 40-feet temporary and 10-feet permanent in wetland
areas.
Response: The 40 feet suggestion and 10 feet requirement have been forward to Lincoln
County and their consulting engineers.
Comment 26: Sewer crossings at streams should be constructed perpendicular to the
channel. Streams and wetlands to be impacted must be restored to their original contours.
Response: Both conditions under the General and Nationwide permit requirements of
N WP 12 will be met.
Comment 27: Where stream crossings are necessary, they should be attached to bridges
or buried beneath the stream bed.
Response: During construction of the project, no culverts are proposed. All crossings
of these resources will either be directionally drilled, or open trench cut within the
requirements of pertinent Section 404 / 401 permits. Regulation of these impacts beyond
project construction will be in accordance with regulations discussed in Section 5.2 of the
EA, or applicable North Carolina minimum standards.
Comment 28: No uncured concrete should be allowed to come in contact with surface
waters.
Response: A condition under the General and Nationwide permit requirements of NWP
12, project construction will adhere to this requirement.
Comment 29: A buffer zone of at least 100 feet should be left between construction
activities and streams.
Response: Avoidance of stream impacts and preservation of forested riparian areas was
maintained to the extent practicable. Engineering constraints (e.g., bedrock) and property
owner issues dictated portions of project alignments where the edge of the floodplain was
not selected. Other areas where the edge of the floodplain was not selected include areas
23

of hillside seeps and other essential habitat that have been avoided for environmental
protection. The majority of the project alignment is located on the east side of Forney
Creek, which is bounded to the east by an existing railroad corridor that will prevent
further encroachment from this direction.
Comment 30: Temporarily impacted wetland areas should be reseeded with native,
annual small grains and be allowed to revert back to natural wetland vegetation.
Response: A condition under the General and Nationwide permit requirements of NWP
12, project construction will adhere to this requirement.
Comment 31: A portion of the upland right of way should be planted with VA-70 or
Korean Lespedeza, ladino clover, and/or partridge pea to provide forage and habitat to
local wildlife.
Response: The new stormwater ordinance requires use of native annual grains.
Comment 32: Slash and trees cleared for corridor construction should be piled at the
edges of the corridor to provide habitat to local wildlife.
Response: The recommendation has been forwarded to Lincoln County and their
consulting engineers.
Comment 33: if necessary, mowing of rights -of -way should be conducted on 2-3 year
intervals and not occur between April 1 and October 1.
Response: The recommendation has been forwarded to Lincoln County and their
consulting engineers.
Comment 34: Stringent erosion control measures should be implemented during project
construction.
Response: The response to Comment 18 above details the County's new Erosion and
Sedimentation Control regulations. The ordinance is included in Appendix C of the EA.
Comment 35: Herbaceous ground cover should be planted on all disturbed areas within
5-10 days of completion.
Response: Lincoln County's new Erosion and Sedimentation Control Ordinance requires
that exposed areas be reseeded or otherwise protected from erosion within 15 working
days or 21 calendar days.
Comment 36: Utility lines should be located away from streams along floodplain edges
and contours.

Response: Engineering constraints (e.g., bedrock) and property owner issues dictated
some portions of project alignments where the edge of the floodplain was not selected.
Other areas where the edge of the floodplain was not selected include hillside seeps and
other essential wildlife habitats. The majority of the project alignment is located on the
east side of Forney Creek, which is bounded to the east by an existing railroad corridor
which will prevent further encroachment from this direction.
