Subject: Correction Change Pages'for
NPDES Permit NCO084565
The Harbour WTP - Wells #1 and #2, Class PC-1
200 Bay Harbour Road, near Mooresville
Iredell County
Dear Mr. Konsul:
The Division has noted errors in the permit issued October 1, 2018. We therefore submit this
correction and change -pages. Please insert these change -pages into your active permit and
discard the old pages. Corrections include:
cover letter dated October 1, 2018 (see 3a. and 3b.)
in Section 1, see table footnotes 5. and 6.
We have also clarified text in section A. (3.).
The Division of Water Resources (DWR of the Division) has approved your application to renew
the subject permit. Accordingly, we are forwarding the attached NPDES discharge permit. This
permit is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and
the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection
Agency dated October 15, 2007 (or as subsequently amended).
The Division has considered your Engineering Alternatives Analysis (EAA) submitted with
your application to renew. The EAA presents present -value costs and rationale for discharges to
a publicly owned treatment works (POTW), land -based disposal, surface irrigation, reuse, and
discharge to surface -waters of the State. DWR concurs that a discharge to surface waters is the
best viable disposal alternative based on cost.
Changes to the Permit Draft and Previous Permit —
1. Based on a Permittee-corrected BIMS database, DWR has confirmed that this facility's
average monthly wasteflow is less than 30,000 gpd. Therefore, a composite sampler, as
presented in the draft permit, is no longer required.
2. Based on reasonable potential to exceed respective water -quality standards, this renewal
adds new permit limits for Total Chloride, Total Lead; Total Copper, and Total Zinc and
Total Manganese [see section A. (1)].

Electronic submissions must start by the dates listed in the "Reporting Requirements" section
above.
3. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an
electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to
the Division. Requests for temporary electronic reporting waivers 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 submitting monitoring data and reports. The duration of a
temporary waiver shall not exceed 5 years and shall thereupon expire. At such time, monitoring
data and reports shall be submitted electronically to the Division unless the permittee re -applies for
and is granted a new temporary electronic reporting waiver by the Division. Approved electronic
reporting waivers are not transferrable. Only permittees with an approved reporting waiver request
may submit monitoring data and reports on paper to the Division for the period that the approved
reporting waiver request is effective.

Subject: Issuance of NPDES Permit NCO084565
The Harbour WTP - Wells #1 and #2, Class PC-1
200 Bay Harbour Road, near Mooresville
Iredell County
Dear Mr. Konsul:
The Division of Water Resources (DWR of the Division) has approved your application to renew
the subject permit. Accordingly, we are forwarding the attached NPDES discharge permit. This
permit is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and
the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection
Agency dated October 15, 2007 (or as subsequently amended).
The Division has considered your Engineering Alternatives Analysis (EAA) submitted with
your application to renew. The EAA presents present -value costs and rationale for discharges to
a publicly owned treatment works (POTW), land -based disposal, surface irrigation, reuse, and
discharge to surface -waters of the State. DWR concurs that a discharge to surface waters is the
best viable disposal alternative based on cost.
Changes to the Permit Draft and Previous Permit —
1. Based on a Permittee-corrected BIMS database, DWR has confirmed that this facility's
average monthly wasteflow is less than 30,000 gpd. Therefore, a composite sampler, as
presented in the draft permit, is no longer required.
2. Based on reasonable potential to exceed respective water -quality standards, this renewal
adds new permit limits for Total Chloride, Total Lead; Total Copper, and Total Zinc and
Total Manganese [see section A. (1.)].
3. Based on DWR/CWS discussions during the pre -draft review (June 22, 2018), Special
Condition A. (3.) details limits and compliance deadlines as:
a. compliance to metals limits begins on -or -before the expiration date of this permit.
b. compliance to Total Chloride limits begins on -or -before September 30, 2021.
DWR may reopen this permit to incorporate new data, as warranted [see Special
Condition A. (3.)].

5. DWR discontinued monitoring for Total Iron [no standard]; no longer a parameter of
concern.
6. Lastly, we added Total Hardness monitoring required to calculate future compliance for
metals in dissolved fraction.
Division records show that you have successfully registered with the eDMR Program. Please be
reminded that until the state's eDMR application is approved compliant with EPA's Cross -
Media Electronic Reporting Regulation (CROMERR), all permittees must continue to submit
hardcopy of DMRs as backup to eDMR reporting [see details Section A. (4.)].
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable, you have the right to an adjudicatory hearing upon written request within thirty
(30) days following receipt of this letter. This request must take the form of a written petition,
conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of
Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-6714).
Unless such demand is made, this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division
may modify or revoke and reissue this permit. This permit does not affect your legal
requirements to obtain other permits required by the Division of Water Resources, the Division
of Land Resources, the Coastal Area Management Act or any other federal or local government.

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, NC 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 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.

A. (3.) PERMIT REOPENER - TO INCORPORATE NEW TREATMENT OPTIONS
[G.S. 143-215.3(a)(2)]
The Division may re -open this permit to incorporate proposed revisions to treatment technologies and
permit limits in accord with scheduled compliance deadlines for:
a) Dissolved metals
b) Total Chlorides
[in accord with section A. (1.), footnotes 5 and 6]
A. (4.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
[G.S. 143-215.1(b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and
program reports. The final NPDES Electronic Reporting Rule was adopted and became effective on
December 21, 2015.
NOTE: This special condition supplements or supersedes the following sections within Part II of this
permit (Standard Conditions for NPDES Permits):
• Section B. (11.) Signatory Requirements
• Section D. (2.)
• Section D. (6.)
• Section E. (5.)
Reporting
Records Retention
Monitoring Reports
1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)1
The permittee shall report discharge monitoring data electronically using the NC DWR's
Electronic Discharge Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. Until such time that the state's
eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation
(CROMERR), permittees will be required to submit all discharge monitoring data to the state
electronically using eDMR and will be required to complete the eDMR submission by printing,
signing, and submitting one signed original and a copy of the computer printed eDMR to the
following address:
NC DEQ / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
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,
Page 5 of 7

Permit NC0084565
2, 3) or alternative forms approved by the Director. Duplicate signed copies shall be submitted to
the mailing address above. See "How to Request a Waiver from Electronic Reporting" section
below.
Regardless of the submission method, the first DMR is due on the last day of the month following
the issuance of the permit or in the case of a new facility, on the last day of the month following the
commencement of discharge.
Starting on December 21, 2020, the permittee must electronically report the following compliance
monitoring data and reports, when applicable:
Sewer Overflow/Bypass Event Reports;
Pretreatment Program Annual Reports; and
Clean Water Act (CWA) Section 316(b) Annual Reports.
The permittee may seek an electronic reporting waiver from the Division (see "How to Request a
Waiver from Electronic Reporting" section below).
2. Electronic Submissions
In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the time
of each electronic submission. The permittee should use the EPA's website resources to identify
the initial recipient for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities means the
entity (EPA or the state authorized by EPA to implement the NPDES program) that is the
designated entity for receiving electronic NPDES data [see 40 CFR 127.2(b)].
EPA plans to establish a website that will also link to the appropriate electronic reporting tool for
each type of electronic submission and for each state. Instructions on how to access and use the
appropriate electronic reporting tool will be available as well. Information on EPA's NPDES
Electronic Reporting Rule is found at:
https://www.federalre ister.gov/documents/2015/10/22/2015-24954/national-pollutant-discharge-
elimination-system-npdes-electronic-reporting-rul e
Electronic submissions must start by the dates listed in the "Reporting Requirements" section
above.
3. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an
electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to
the Division. Requests for temporary electronic reporting waivers 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 submitting monitoring data and reports. The duration of a
temporary waiver shall not exceed 5 years and shall thereupon expire. At such time, monitoring
data and reports shall be submitted electronically to the Division unless the permittee re -applies for
and is granted a new temporary electronic reporting waiver by the Division. Approved electronic
reporting waivers are not transferrable. Only permittees with an approved reporting waiver request
may submit monitoring data and reports on paper to the Division for the period that the approved
reporting waiver request is effective.

4. Si2natory Requirements [Supplements Section B. (11.) (b) and Supersedes Section B. (11.)
11
All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part
II, Section B. (I 1.)(a) or by a duly authorized representative of that person as described in Part II,
Section B. (I 1.)(b). A person, and not a position, must be delegated signatory authority for eDMR
reporting purposes.
For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR user
account and login credentials to access the eDMR system. For more information on North
Carolina's eDMR system, registering for eDMR and obtaining an eDMR user account, please visit
the following web page:

Certification. Any person submitting an electronic DMR using the state's eDMR system shall
make the following certification [40 CFR 122.22]. NO OTHER STATEMENTS OF
CERTIFICATION WILL BE ACCEPTED:
"I certify, under penalty of law, that this document and all attachments were prepared under my
direction or supervision in accordance with a system designed to assure that qualified personnel
properly gather and evaluate the information submitted. Based on my inquiry of the person or
persons who manage the system, or those persons directly responsible for gathering the
information, the information submitted is, to the best of my knowledge and belief, true, accurate,
and complete. I am aware that there are significant penalties for submitting false information,
including the possibility of fines and imprisonment for knowing violations. "
5. Records Retention [Supplements Section D. (6.)]
The permittee shall retain records of all Discharge Monitoring Reports, including eDMR
submissions. These records or copies shall be maintained for a period of at least 3 years from the
date of the report. This period may be extended by request of the Director at any time [40 CFR
122.41].

UPDATED BIMS DATA REVIEW / CHANGES TO THE DRAM' PERMIT:
1. DWR's re-examination of the corrected database (downloaded 04Sep2018) suggests a wasteflow
average of 0.00372 MGD. Unlike the previous, this average (< 0.030 MGD) suggests that a
composite sampler is not required [NCAC 2B.0505 (c)]. Therefore, DWR will delete language
requiring a composite sampler, as detailed in cover letter and DRAFT Special Condition A. (3.).
2. Reasonable Potential Analysis (RPA) — Updated, corrected databases (thru sep2018) continue to
show reasonable potential to exceed each respective surface water -quality standard for copper,
zinc, lead, chloride, and manganese (See attached RPA). No changes from permit draft
recommended.

I will pass the information along. Would you be able to provide some clarification on this comment:
"Finally, anticipating a permit draft, you may want to consider the need to install effluent diffusers that may be
modeled for dilution by Lake Norman. We anticipate these sodium ion -exchange (IE) treatment systems will
likely discharge under zero -flow receiving -stream conditions [7Q10 and 30Q2 = 0.0 cfs]. We anticipate
therefore the need and benefit of dilution credit, considering parameters of concern (POCs) likely to be limited,
each at its respective water -quality standard"
The softeners do not discharge directly into the lake.

Mr. Bond: I appreciate your efforts in reviewing the data. I believe I have enough usable data, beyond that
which may need amending by CWS, to conduct a credible reasonable potential analysis (RPA) for renewal.
One last comment for future reporting and corrections; if a given parameter is not detected, please inform CWS
to report the laboratory's minimum practical quantitation level (PQL) for the test -method conducted - not "0."
We need the test PQL for all analyses reported; zero is not appropriate and a reporting violation.
Respectfully,
Joe R. Corporon, L. G.

Mr. Bond: I'm encouraged that you are sensitive to "...time [spent] on the spreadsheet."
I have verified that all three subject facilities are registered for eDMR. BIMS data -dumps should reflect any
amended reports (as Version 2), but as you see from the previously provided XL file, reporting issues remain.
Without resolving these issues for NCO084565 in BIMS, I may not proceed with renewal. Please verify with
your client that they have amended their eDMRs, and submitted them using the proper eDMR verification
process (check all three facilities; I have yet to download data for the other two).
I regret that I may not make the deadline for Public Notice by COB tomorrow as I had hoped for NC0084565.
My next window for Public Notice is COB April 3, if these reporting issues may be resolved in time.
Finally, anticipating a permit draft, you may want to consider the need to install effluent diffusers that may be
modeled for dilution by Lake Norman. We anticipate these sodium ion -exchange (IE) treatment systems will
likely discharge under zero -flow receiving -stream conditions [7Q10 and 30Q2 = 0.0 cfs]. We anticipate

Mr. Corporon,
I had a conversation with CWS, and they said that they were aware of this problem at some sites and that amended
DMR's should have been submitted. Do you have any way to verify if amended DMR's have been submitted for this
permit?
I just want to make sure before I spend time on the spreadsheet.

Mr. Bond - good timing.
From my renewal log: NCO084565
15Mar2018 -- initiated file review; researched BIMS database for reasonable potential analyses (RPA); started
permit draft and Fact Sheet; drafted site map. It is my intent to submit this draft for the next Public Notice day,
21 March, if data can be resolved.
You may be able to assist me with the BIMS data review (see attached XL file — Jan2014 to Mar2018). There is
reported a mix of measurement units, particularly for metals, ug/L vs. mg/L vs. ppt (note my attempts to
resolve on the spreadsheet). This may require amended DMRs from the Permittee.
Please remind the Permittee and the lab that units of measure must reflect analyses with respect to each
parameter's surface water -quality standard; in the case of metals, ug/L. If you can resolve this ambiguous
reporting, it would be a great help.
Other renewals NC0086606, NCO086592 to follow, as priorities allow. I trust these other facilities do not have
similar reporting problems?

DATA REVIEW SUMMARY / BIMS DOWNLOADS:
1. For renewal: Updated effluent parameters of concern (POC) in accordance with Ion -Exchange
(IE) WTP technology guidelines (2009); updated permit template, facility location, facility
description, and added 8 Digit HUC to the map; Added parameter monitoring and limits based on
zero -flow conditions (IWC=100%), see Reasonable Potential Analysis (RPA).
2. DMR's from January 2014 thru February 2018 reported an average potable flow of 0.0132 MGD.
The maximum reported a waste -flow rate of 0.5569 MGD (Jan2018) was judged a reporting error
(not used for RPA); identified 0.0188 MGD as the maximum monthly -average flow rate for
treated wastewater effluent (2017); this figure was used for the RPA analysis, per WTP Strategy
2009.

RENEWAL SUMMARY
1. Flow Monitoring - monitoring frequency set at 2/monthly; edited table footnote [A. (1.)] to require
both "flow rate and flow duration," logs to be kept available for DWR review. Average flow
exceeds 30,000 gpd, therefore this facility, averaging 132,000 gpd, requires "Composite" sampling.
Renewal provides a compliance period of one (1) year from the permit Effective date [see section
A. (3.)].
2. Permit Compliance History- BIMs records indicates only two (2) violations, none proceeding
to enforcement; one frequency NOV for failure to report Chloride (Jun2015); and a NOD for
TRC @ 50 ug/L (Oct2016).
3. Previous Special Conditions -- CWS responded to previous Special Condition A. (3.) by providing
the required Discharge Alternatives Evaluation (DAE) as attachment to its application to renew.
The Division concurs with conclusions that a surface -water discharge is the best discharge
alternative based on cost, however this renewal requires an amended Special Condition and
compliances deadlines [see permit A. (3.)].
4. Effluent Data Concerns - Data suggest that the current treatment system is not adequate to meet
Surface Water Quality Standards for dissolved metals and for Total Chloride, considering a
discharge to stream Class WS-IV; B; CA [Water Supply; swimmable; habitat -critical area]. The
Permittee is admonished to consider applying an alternate potable -water treatment technology
other than sodium ion -exchange (IE), or extend its discharge into the lake, employing an effluent
diffuser to afford effluent dilution, or other alternatives to be determined.
5. Reported Units of Measure - The Permittee's effluent databases for this past permit cycle are
reported with conflicting units of measure. In addition, the Permittee has reported analytical data
as "not detected," entering "0" on the DMR/eDMR instead of a given test procedure's practical
Page 12

quantitation level (PQL). This is a permit violation. Inconsistently reported DMRs/eDMRs
require amendment.
6. Reasonable Potential Analysis (RPA) — Databases for copper, zinc, lead, chloride, and
manganese, show reasonable potential to exceed their respective surface water -quality standards.
Per WTP permitting guidance, Total Iron is no longer considered a parameter of concern, and
monitoring is hereby discontinued. Total Manganese => monitoring only/no limit (WS waters).
Considering a discharge under zero -flow receiving -stream conditions [7Q10/3OQ2 = 0.0 cfs],
each metal requires a permit limit equal to its surface water -quality standard. In addition, future
soluble metals calculations require monitoring for Total Hardness, effluent only [upstream not
possible under zero -flow conditions].
7. Permit Compliance Periods — For permit reopener rationale, see Section A. (3.). This permit
includes deadlines for compliance regarding Total Chlorides, dissolved metals limits, and
composite sampling methods (Table 3)

NPDES Implementation of Instream Dissolved Metals Standards - Freshwater
The NC 2007-2015 Water Quality Standard (WQS) Triennial Review was approved by the NC
Environmental Management Commission (EMC) on November 13, 2014. The US EPA subsequently
approved the WQS revisions on April 6, 2016, with some exceptions. Therefore, metal limits in draft
permits out to public notice after April 6, 2016 must be calculated to protect the new standards - as
approved.

General Information on the Reasonable Potential Analysis (RPA)
The RPA process itself did not change as the result of the new metals standards. However, application
of the dissolved and hardness -dependent standards requires additional consideration to establish the
numeric standard for each metal of concern of each individual discharge.
The hardness -based standards require some knowledge of the effluent and instream (upstream)
hardness and so must be calculated case -by -case for each discharge.
Metals limits must be expressed as `total recoverable' metals in accordance with 40 CFR 122.45(c).
The discharge -specific standards must be converted to the equivalent total values for use in the RPA
calculations. We will generally rely on default translator values developed for each metal (more on that
below), but it is also possible to consider case -specific translators developed in accordance with
established methodology.
RPA Permitting Guidance/WQBELs for Hardness -Dependent Metals - Freshwater
The RPA is designed to predict the maximum likely effluent concentrations for each metal of concern,
based on recent effluent data, and calculate the allowable effluent concentrations, based on applicable
standards and the critical low -flow values for the receiving stream.
If the maximum predicted value is greater than the maximum allowed value (chronic or acute), the
discharge has reasonable potential to exceed the standard, which warrants a permit limit in most cases.
If monitoring indicates a pollutant is not present (i.e. consistently reported below detection level), then
the Division may remove the monitoring requirement in the reissued permit.
1. To perform a RPA on the Freshwater hardness -dependent metals the Permit Writer compiles the
following information:
• Critical low flow of the receiving stream, 7Q10 (the spreadsheet automatically calculates the
1 Q 10 using the formula 1 Q 10 = 0.843 (s7Q 10, cfs) 0.993
• Effluent hardness and upstream hardness, site -specific data is preferred
• Permitted flow
• Receiving stream classification
2. To establish the numeric standard for each hardness -dependent metal of concern and for each
individual discharge, the Permit Writer must first determine what effluent and instream (upstream)
hardness values to use in the equations.
The permit writer reviews DMR's, Effluent Pollutant Scans, and Toxicity Test results for any
hardness data and contacts the Permittee to see if any additional data is available for instream
hardness values, upstream of the discharge.
Page 15

If no hardness data is available, the permit writer may choose to do an initial evaluation using a
default hardness of 25 mg/L (CaCO3 or (Ca + Mg)). Minimum and maximum limits on the
hardness value used for water quality calculations are 25 mg/L and 400 mg/L, respectively.
If the use of a default hardness value results in a hardness -dependent metal showing reasonable
potential, the permit writer contacts the Permittee and requests 5 site -specific effluent and upstream
hardness samples over a period of one week. The RPA is rerun using the new data.
The overall hardness value used in water -quality calculations follows as Combined Hardness
(chronic):
_ (Permitted Flow, cfs *Avg. Effluent Hardness, mgZL) x (s7Q10, cfs *Avg. Upstream Hardness. mg/L)
(Permitted or assumed Flow, cfs + s7Q 10, cfs)
[Combined Hardness for acute is the same, but the calculation uses the 1Q10 flow.]
3. The permit writer converts the numeric standard for each metal of concern to a total recoverable
metal, using the EPA Default Partition Coefficients (DPCs) or site -specific translators, if any have
been developed using federally approved methodology.
EPA default partition coefficients or the "Fraction Dissolved" converts the
value for dissolved metal at laboratory conditions to total recoverable metal
at in -stream ambient conditions. This factor is calculated using the linear
partition coefficients found in The Metals Translator: Guidance for
Calculating a Total Recoverable Permit Limit from a Dissolved Criterion
(EPA 823-B-96-007, June 1996) and the equation:
Cdiss — 1
total po SS
Where:
ss = in -stream suspended solids concentration [mg/1], minimum of 10 mg/L
used, and
Kpo and a = constants that express the equilibrium relationship between
dissolved and adsorbed forms of metals. A list of constants used for each
hardness -dependent metal can also be found in the RPA program under a
4. The numeric standard for each metal of concern is divided by the default partition coefficient (or
site -specific translator) to obtain a Total Recoverable Metal at ambient conditions.
In some cases, where an EPA default partition coefficient translator does not exist (ie. silver), the
dissolved numeric standard for each metal of concern is divided by the EPA conversion factor to
obtain a Total Recoverable Metal at ambient conditions. This method presumes that the metal is
dissolved to the same extent as it was during EPA's criteria development for metals. For more
information on conversion factors see the June 1996 EPA Translator Guidance Document.
Page 16

5. The RPA spreadsheet uses a mass balance equation to determine the total allowable concentration
(permit limits) for each pollutant using the following equation:
Ca = (s7Q 10 + Qw) (Cwgs)—(s7Q10) (Cb)
Qw
Where: Ca = allowable effluent concentration (µg/L or mg/L)
Cwqs = NC Water Quality Standard or federal criteria (µg/L or mg/L)
Cb = background concentration: assume zero for all toxicants except NH3* (µg/L or mg/L)
Qw = permitted effluent flow (cfs, match s7Q 10)
s7Q 10 = summer low flow used to protect aquatic life from chronic toxicity and human health
through the consumption of water, fish, and shellfish from noncarcinogens (cfs)
* Discussions are on -going with EPA on how best to address background concentrations
Flows other than s7Q 10 maybe incorporated as applicable:
IQ 10 = used in the equation to protect aquatic life from acute toxicity
QA = used in the equation to protect human health through the consumption of water, fish,
and shellfish from carcinogens
30Q2 = used in the equation to protect aesthetic quality
6. The permit writer enters the most recent 2-3 years of effluent data for each pollutant of concern.
Data entered must have been taken within four and one-half years prior to the date of the permit
application (40 CFR 122.21). The RPA spreadsheet estimates the 95th percentile upper
concentration of each pollutant. The Predicted Max concentrations are compared to the Total
allowable concentrations to determine if a permit limit is necessary. If the predicted max exceeds
the acute or chronic Total allowable concentrations, the discharge is considered to show reasonable
potential to violate the water quality standard, and a permit limit (Total allowable concentration) is
included in the permit in accordance with the U.S. EPA Technical Support Document for Water
Quality Based Tonics Control, published in 1991.
7. When appropriate, permit writers develop facility specific compliance schedules in accordance with
the EPA Headquarters Memo dated May 10, 2007 from James Hanlon to Alexis Strauss on 40 CFR
122.47 Compliance Schedule Requirements.
8. The Total Chromium NC WQS was removed and replaced with trivalent chromium and hexavalent
chromium Water Quality Standards. As a cost savings measure, total chromium data results may be
used as a conservative surrogate in cases where there are no analytical results based on chromium
III or VI. In these cases, the projected maximum concentration (95th %) for total chromium will be
compared against water quality standards for chromium III and chromium VI.
Page 17

9. Effluent hardness sampling and instream hardness sampling, upstream of the discharge, are inserted
into all permits with facilities monitoring for hardness -dependent metals to ensure the accuracy of
the permit limits and to build a more robust hardness dataset.

Section I — Introduction
Purpose of Study
Carolina Water Service Inc. of North Carolina owns and operates a public water supply
and distribution system serving the neighborhoods of The Pointe, The Harbor and the
Farms, located in Iredell County, North Carolina (reference Figure 1 — Vicinity Map). The
system currently serves 1,544 connections, includes 34 deep wells, two elevated storage
tanks, and water treatment facilities. The overall water system, including the wells and
elevated storage tanks, is shown on Figure 2. Also highlighted on Figure 2 are the
location and connected wells to three water treatment facilities containing water
softening equipment.
Background and Scope of Report
Each of the three water softening treatment facilities generates a backwash discharge
on the well sites shown on Figure 2 where the facilities are located. Each of these
backwash discharges are generating under NPDES permits issued on October 1, 2013.
Each of these permits is included in Appendix A, and is summarized in Table 1 below:

Each of the permits expires at Midnight on March 31, 2018.
As a result of concerns as to violation of North Carolina Water Quality Standards from
these discharges, each of the permits requires a "Discharge Alternatives Evaluation."
This evaluation is to be completed by October 2, 2017. This evaluation as stated in each
permit is to cover three to four options as detailed below:
Discharge Alternatives Evaluation
In an effort to comply with North Carolina Water Quality Standards (WQS) for the following parameters:
chloride, manganese, lead, and total dissolved solids; the Permittee shall assess potential discharge
alternatives. It is recommended that the evaluation thoroughly assess 3 to 4 of the following alternatives:
1. Connect Discharge to WWTP: Determine whether the wastewater can be discharged to a
Wastewater Treatment Plant (WWTP) or pumped and hauled to a WWTP. Approval or disapproval
from the municipality should be acquired.
5

PER DISCHARGE ALTERNATIVES ANALYSIS
2. Obtain a Non -Discharged Permit: Eliminate the surface water discharge by obtaining a non -
discharge permit for spray irrigation, infiltration, or subsurface disposal (on -site drainfield, infiltration
gallery, injection wells).
3. Install Wastewater Treatment: Install improved wastewater treatment to enable the facility effluent
to consistently comply with Water Quality Standards. If this is not technically feasible or cost
prohibitive, please explain and provide cost estimates.
4. Use Alternative Water Source: Obtain drinking water from another source (nearest County, City
or Town or other wells) so either the discharge is eliminated or compliance with WQS's is achieved.
5. Use Alternative Water Treatment Method: Install alternative and/or innovative water treatment
methods or operational improvements that do not produce noncompliant wastewaters. For
example, installing a recycled iron/manganese filtration system with no discharge.
6. Discharge to Larger Stream: Relocate the facility's discharge to a larger receiving stream and
determine if limits can be achieved given the increased dilution.
7. Combination of Alternatives: Employ any combination of the alternatives listed above that would
result in achieving compliance with Water Quality Standards.
The evaluation shall include a present value of costs analysis for all technologically feasible options as
outlined in the Division's "Engineering Alternatives Analysis Guidance Document." This document can be
found at: http://portal.ncdenr.org/web/wq/swp/ps/npdes.permits.
The scope and purpose of this Preliminary Engineering Report is to provide the details
and results of the Discharge Alternatives Evaluation in accordance with the NPDES
Permits. As the treatment facilities are components of the overall water system and as
such the water treatment is required in total to meet the system requirements, this study
has been combined to consider all of the three treatment facilities collectively and is
therefore intended to comply with the conditions in all three permits.
6

PER DISCHARGE ALTERNATIVES ANALYSIS
Section II — Discharge of Existing Facilities
2.01 Review of Existing Facilities
A site plan and building/softener treatment facilities plan for each of the three
discharges are provided in Appendices B, C and D respectively. As can be seen from
each of these site plans, the point of discharge for the softener backwash after passing
through settling tanks is on each well site, and each well site is slightly over one acre
in size. This represents significant constraint in terms of available land area for potential
alternatives. Each well site is relatively surrounded by existing residential development.
It should be noted that there is a significant difference in the scale of the water
treatment system and softener backwash between the lowest and highest discharges.
In 2013 a study was completed to assess the viability of an interconnection from the
Town of Mooresville system to The Point Water System (see Appendix E — WSP
Report). This interconnect was completed as depicted in the WSP Report and was
subject to an executed agreement with the Town (reference Appendix F). This
agreement set a limit on the amount of water that could be purchased by CWS at
656,000 GPD.
As shown in Appendix G, the total system yield of all 34,producing wells is 1517.5 GPM
and the yield of the wells contributing to the three softener installations is 724.5 GPM.
Thus, a replacement of the yield from the yield from those wells contributing to the
softener operations would be approximately 522,000 GPD. (Note: wells must supply
the required yield for the number of connections in a 12 hour pumping time.) This
indicates the current agreement with the Town would be able to replace the delivered
capacity of 19 wells contributing to the softener systems: However, water use records
from CWS indicate peak demands have reached approximately 1.5 MGD, thus
additional water from Mooresville beyond the 656,000 GPD agreement would be
required to meet demands.
There are no community nor public sewer within The Point/Harbor/Farms subdivisions
served by this water system — all lots are served by on -site septic.
2.02 Selection of Alternatives for Analysis
The following paragraphs address the potential alternatives identified in the NPDES
permits and identify the three alternatives deemed viable for analysis.
Connect Discharge to a WWTP
There is no public or private central sewage collective system within The
Point/Harbor/Farms developments. The Point Golf Club is served by a private,
small package waste treatment plant (25,000 GPD) which does not represent
a viable option for treating the softener backwash as it is a land application
disposal and salinity concentration/build-up would be a concern.
7

PER DISCHARGE ALTERNATIVES ANALYSIS
The Town of Mooresville has a pump station serving a school to the north of
the site as shown on Figure 3. Initial contact with the Town indicated reluctance
in affording service, however this option has been analyzed given the potential
for negotiating service due to the relative small volume of the softener
backwash (approximately 37,000 gallons/month). tG-( AL- Lc>-,,, f �'J
2. Obtain a Non -Discharge Permit 't�&2c, 5%4�4
This alternative has been discounted due to the lack of available land and the
potential toxicity to soils in a surface of sub -surface disposal system.
3. Install Wastewater Treatment
Treatment of the softener backwash to remove the salt concentration is limited
to very expensive options such as reverse osmosis or desalinization, which in
the end also results in a by-product which must be disposed of such as an even
more concentrated brine solution.
Additional treatment in the form of Zero Liquid Discharge (ZLD) has been
evaluated to further reduce the brine stream to a solids for disposal based on
crystallization technology.
4. Use Alternative Water Source
CWS already has a correction to the Mooresville system and an agreement
allowing purchase of up to 656,000 GPD. Based on a water modeling analysis
of the existing 8" connection, water could be delivered at required flow and
pressure (based upon the fire flow tests — referenced in Appendix H).
As noted previously, water use has reached 1.5 MGD in previous years, so an
alternative to replace the 19 softener wells with Town of Mooresville supply
would need to increase the Mooresville agreement to approximately 1.0 MGD.
To deliver this supply, it was determined from hydraulic modeling that the
existing 8" main would need to be increased to 12".
5. Use Alternative Water Treatment Method
Utilization of a polyphosphate sequestering agent to "capture" the calcium ions,
while an option, has been rejected by CWS as the method has less than
acceptable performance for delivery of water without scale forming properties.
A review of several "no salt" treatment methods identified an alternative "water
conditioning" treatment unit manufactured by Morrill Industries called "Ecoflow
Water Conditioner." The unit utilizes ceramic media to stabilize the scale
forming properties (see Appendix J).
While the alternatives to water softening are purported to fully neutralize the
potential scaling problems resulting from hard water, CWS previous experience
indicates the results are not typically consistent and may still result in consumer
E-1

PER DISCHARGE ALTERNATIVES ANALYSIS
complaints. For the purpose of this evaluation, this alternative was not further
evaluated.
6. Discharge to Larger Stream
The water system, wells and treatment facilities are located on the Brawley
School Road Peninsula and are completely surrounded by Lake Norman, so
larger streams are not available.
7. Combination of Alternatives
No combination of alternatives were identified meriting analysis.

PER DISCHARGE ALTERNATIVES ANALYSIS
Section III — Analysis of Alternatives
3.01 Selection of Alternatives for Analysis
Connection to Mooresville System
As shown on Figure 3, the three installations of water softening facilities are all located
within proximity of Brawley School Road. This alternative will require installation of
pumps at each softener installation and pump lines extended to Brawley School Road
to join a common pump line as depicted on Figure 3. This common line would then
extend along Brawley School Road to McKendree Road, then to an easement
controlled by CWS, and then to Forest Lake School to access the Town's pump station
as shown on Figure 3.
Submersible pumps would be installed at each well location in existing tankage to take
advantage of tank volume for pump cycling.
As presented in Appendix K, the estimated Capital and Annualized Operational
Maintenance Cost for this alternative is $18,809,640.00.
Note that for the purpose of this analysis no costs for demolition or removal of existing
facilities at the 19 wells or their abandonment have been included.
3.02 Installed Wastewater Treatment at Harbour Well #4
For the purposes of this analysis the alternative for onsite treatment of the brine
softener backwash was based upon the removal of the salinity to produce a dried salt
cake for reuse or offsite disposal and continued discharge of treated effluent allowing
for elimination of any chronic toxicity in the effluent stream.
The proposed brine backwash treatment process would consist of pre -filtration, multi-
stage evaporation, and crystallization to essentially produce a distilled water effluent
and dry salt solids. The combined discharge in all three NPDES permits is 0.02 MGD
Monthly Average Flow or approximately 700 GPD. As the amount of brine backwash
is dependent upon the volume of water being softened, thus the daily backwash
volume will vary, the design basis was to continue to use the existing onsite septic
tanks as pump storage to feed the waste treatment system. The treatment system has
been selected on the basis of the monthly average brine discharge as currently
permitted for each well softener installation. A schematic of the treatment system is
presented in Appendix L and Figure 4 depicts the location of the treatment systems at
each well. The site plans and existing buildings at each well are included in Appendix
M.
For the purposes of this evaluation, it is assumed that the WTP unit would be installed
in a new building at each of the three well sites, and that a brine backwash feed pump
would be installed in the existing septic tank now receiving the brine backwash before
discharge. There are two septic tanks at each of the three wells. Brine backwash pump
10

PER DISCHARGE ALTERNATIVES ANALYSIS
would be installed in the first septic tank and treated effluent returned to the second
tank for continual discharge. An example of this arrangement is depicted on Figure 5.
The results of the cost analysis presented in Appendix N for this alternative indicates
a Total Capital and Operations and Maintenance Cost of $2,316,015.00.
3.03 Use Alternative Water Source
While an amendment to the CWS agreement with the Town of Mooresville has not
been executed, the indication from contact with Town staff suggests this is a possible
alternative. Therefore an analysis was conducted to deliver a volume of water equal
to the capacity of the 19 wells which would be abandoned under this alternative at a
delivery pressure sufficient to fill the existing elevated storage tanks. A hydraulic
model of the existing 8" connection was performed and indicated the full 724.5 GPM
could not be delivered at the required pressure without upsizing the connection to 12".
Thus this alternative includes upsizing this line as depicted on Figure 6, a distance of
4800 LF. This upsizing (line replacement) would also include installation of new 12"
meter and backflow preventer with increased tap size on the Town's water main.
The rate and fee schedule for the Town is presented in Appendix O. For the purpose
of this analysis the water purchased is assumed to be 1,044,000 GPD.
11

PER DISCHARGE ALTERNATIVES ANALYSIS
Section IV — Analysis Results and Recommendations
4.01 Analysis Results
The Discharge Alternatives Evaluation of seven alternatives identified three viable
options for analysis. These options included elimination of discharge and pumping to
the Town of Mooresville, onsite softener backwash treatment and abandonment of
wells and softeners with replaced water from the Town of Mooresville. The results of
this analysis indicate very similar costs for either connection to the Mooresville sewer
system or onsite treatment. In view of the fact that Town staff have indicated that there
would likely be a negative response to a request for treating the softener brine
backwash, the option to install onsite treatment appears to be the most viable
alternative.
4.02 Recommendations
Based upon the results of this evaluation it is recommended that this PER be
submitted to NCDEQ for review in support of renewal of the NPDES permits and to
proceed with design of the onsite treatment facilities and regiment for an Authorization
to Construct the brine backwash treatment facilities.

Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued pursuant
to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement
between North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007 (or as
subsequently amended).
Thank you for your expedited response to my email dated August 12, 2013. Regarding your two
comments made on the final permit the Division offers the following responses. NPDES understands
that a discharge from Ion Exchange backwash is not always predictable. As a result, many Ion
Exchange WTPs choose to initiate a manual backwash and proceed to collect aliquot samples at spaced
intervals to obtain a representative sample. Some Ion Exchange WTPs have chosen to install composite
samplers to decrease the operator responsibilities but this can be costly. NPDES appreciates your
efforts to schedule sampling visits to coincide with expected backwashing or to manually place the
softeners into backwash mode in order to collect a sample. The Division does find this practice to be
acceptable. Note that a representative sample is considered to be the wastewater being discharged and
not the static wastewater in the holding tank.
Regarding your comment on turbidity sampling, please note that in a letter dated Feb. 25, 2009 from
EPA Region IV the state is obligated to put turbidity monitoring in the NPDES permit. This also

satisfies testing regulations cited in NC Administrative Code 15A 2B .0500. It is recommended that the
test be performed using a turbidity meter.
All the changes made in this permit renewal as compared to the current permit are as follows:
• The receiving waterbody is not listed as Nutrient Sensitive Waters and the maximum discharge
flow is less than 0.05 MGD. Therefore, per the Water Treatment Plant Strategy, Total
Phosphorus and Total Nitrogen monitoring have been removed from the permit.
• Ammonia- nitrogen monitoring was removed from the permit since sampling results did not
show significant concentration levels of ammonia -nitrogen in the effluent.
• Flow monitoring has been increased to twice a month and a footnote was added to the permit
stating that flow shall be measured the same date samples are collected for analysis. If an
instantaneous sample is collected the duration of the discharge event shall be recorded in a log
book and available for inspection.
• Monthly Turbidity monitoring has been added to the permit in accordance with a letter received
from EPA Region IV dated Feb. 25, 2009 and in accordance with Administrative Code Section
15A NCAC 213.0500.
,
• Footnote number 3 was amended under Section A (L) to include the following statement: TRC
limit and monitoring requirement only apply if chlorine is used for disinfection. The Permittee
shall report all effluent TRC values reported by a NC -certified laboratory [including field -
certified]. Effluent values below 50 µg/L will be treated as zero for compliance purposes.
• The wording in Section A. (2.) has been changed and the following paragraph added: If the
Permittee monitors any pollutant more frequently than required by this permit, the results of such
monitoring shall be included in the calculation and reporting of the data submitted on the
Discharge Monitoring Report and all AT Forms submitted. .
• Copper, zinc, and iron effluent samples reported from May 2008 through June 2011 showed
reasonable potential to violate North Carolina Water Quality Standards. Since copper, zinc, and
iron have Action Level standards and should be reviewed in conjunction with quarterly toxicity
testing, it is recommended that monitoring for these parameters remain in the NPDES permit at
a reduced monitoring frequency of quarterly. It is anticipated, that discharge alternatives
assessed as part of the Discharge Alternatives Evaluation, will likely eliminate toxicity failures
in the effluent as well.
• Effluent sampling data evaluated from May 2008 to June 2011 for lead, manganese, chloride,
and total dissolved solids showed reasonable potential to violate North Carolina Water Quality
Standards for all these parameters.

Alternatives Evaluation in the form of a compliance schedule.
• The Supplement to Cover was corrected as requested.
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty

such demand is made, this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may
require modification or revocation and reissuance of the permit. This permit does not affect the legal
requirements to obtain other permits which may be required by the Division of Water Resources or

A. (2.) CHRONIC TOXICITY PASS/FAIT. MONITORING (QUARTERLY)
The permittee shall conduct guarterly 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 90 %.
The testing shall be performed as a Ceriodaphnia dubia 7-day pass/fail test. The tests will
be performed during the months of March, June, September, and December. 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, DWQ Form AT-1 (original) is to be sent to the
following address:
Attention: North Carohna'Division of Water Resources
Environmental Sciences Section
1621 Mail Service Center
Raleigh, N.C. 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental 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 Environmental 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.
If the Permittee monitors any pollutant more frequently than 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.

A. (3.) DISCHARGE ALTERNATIVES EVALUATION
In an effort to comply with North Carolina Water Quality Standards (WQS) for the following
parameters: chloride, manganese, lead, and total dissolved solids; the Permittee shall
assess potential discharge alternatives. It is recommended that the evaluation thoroughly
assess 3 to 4 of the following alternatives:
1. Connect discharge to a WWTP: Determine whether the wastewater can be discharged
to a Wastewater Treatment Plant (WWTP) or pumped and hauled to a
WWTP. Approval or disapproval from the municipality should be
acquired.
2. Obtain a Non -discharge permit: Eliminate the surface water discharge by obtaining a
non -discharge permit for spray irrigation, infiltration, or subsurface
disposal (on -site drainfield, infiltration gallery, injection wells).
3. Install Wastewater Treatment: Install improved wastewater treatment to enable the
facility effluent to consistently comply with Water Quality Standards.
If this is not technically feasible or cost prohibitive, please explain and
provide estimated costs.
4. Use Alternative Water Source: Obtain drinking water from another source (nearest
County, City, or Town or other wells) so either the discharge is
eliminated or compliance with WQS's is achieved.
5. Use Alternative Water Treatment Method: Install alternative and/or innovative water
treatment methods or operational improvements that do not produce
noncompliant wastewaters. For example, installing a recycle
iron/manganese filtration system with no discharge.
6. Discharge to a Larmer stream: Relocate the facility's discharge to a larger receiving
stream and determine if limits can be achieved given the increased
dilution.
7. Combination of Alternatives: Employ any combination of the alternatives listed above
that would result in achieving compliance with Water Quality
Standards.
The evaluation shall include a present value of costs analysis for all technologically feasible
options as outlined in the Division's "Engineering Alternatives Analysis Guidance
Document." This Document can be found at:
http:IIportal.ncdenr.org/webI=1UW1psJnpdes/ ermits.
This evaluation is being requested to determine whether there are any economical and
technologically feasible alternatives available to the Permittee to comply with NC Water
Quality Standards. If one or two -discharge alternatives are available to the Permittee,
please identify the preferred alternative and an estimated timeline for implementation. The
Permittee shall submit the Discharge Alternatives Evaluation to the Division at the address
listed below four years after the effective date of this permit (by October 2, 2017).

Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued pursuant
to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement
between North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007 (or as
subsequently amended).
Thank you for your expedited response to my email dated August 12, 2013. Regarding your two
comments made on the final permit the Division offers the following responses. NPDES understands
that a discharge from Ion Exchange backwash is not always predictable. As a result, many Ion
Exchange WTPs choose to initiate a manual backwash and proceed to collect aliquot samples at spaced
intervals to obtain a representative sample. Some Ion Exchange WTPs have chosen to install composite
samplers to decrease the operator responsibilities but this can be costly. NPDES appreciates your
efforts to schedule sampling visits to coincide with expected backwashing or to manually place the
softeners into backwash mode in order to collect a sample. The Division does find this practice to be
acceptable. Note that a representative sample is considered to be the wastewater being discharged and
not the static wastewater in the holding tank.
Regarding your comment on turbidity sampling, please note that in a Ietter dated Feb. 25, 2009 from
EPA Region IV the state is obligated to put turbidity monitoring in the NPDES permit. This also

All the changes made in this permit renewal as compared to the current permit are as follows:
• The receiving waterbody is not listed as Nutrient Sensitive Waters and the maximum discharge
flow is less than 0.05 MGD. Therefore, per the Water Treatment Plant Strategy, Total
Phosphorus and Total Nitrogen monitoring have been removed from the permit.
• Ammonia- nitrogen monitoring was removed from the permit since sampling results did not

• Flow monitoring has been increased to twice a month and a footnote was added to the permit
stating that flow shall be measured the same date samples are collected for analysis. If an
instantaneous sample is collected the duration of the discharge event shall be recorded in a log
book and available for inspection.
! Monthly Turbidity monitoring has been added to the permit in accordance with a letter received
from EPA Region N dated Feb. 25, 2009 and in accordance with Administrative Code Section
15A NCAC 2B .0500.
• Footnote number 3 was amended under Section A (L) to include the following statement: TRC
limit and monitoring requirement only apply if chlorine is used for disinfection. The Permittee
shall report all effluent TRC values reported by a NC -certified laboratory [including field -
certified]. Effluent values below 50 µg/L will be treated as zero for compliance purposes.
• The wording in Section A. (2.) has been changed and the following paragraph added: If the
Permittee monitors any pollutant more frequently than required by this permit, the results of such
monitoring shall be included in the calculation and reporting of the data submitted on the
Discharge Monitoring Report and all AT Forms submitted. .
• Copper, zinc, and iron effluent samples reported from May 2008 through June 2011 showed
reasonable potential to violate North Carolina Water Quality Standards. Since copper, zinc, and
iron have Action Level standards and should be reviewed in conjunction with quarterly toxicity
testing, it is recommended that monitoring for these parameters remain in the NPDES permit at
a reduced monitoring frequency of quarterly. It is anticipated, that discharge alternatives
assessed as part of the Discharge Alternatives Evaluation, will likely eliminate toxicity failures
in the effluent as well.
• Effluent sampling data evaluated from May 2008 to June 2011 for lead, manganese, chloride,

December 2010, or subsequent versions.
The effluent concentration defined as treatment two in the procedure document is 90 %.
The testing shall be performed as a Ceriodaphnia dubia 7-day pass/fail test. The tests will
be performed during the months of March, June, September, and December. 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, DWQ Form AT-1 (original) is to be sent to the
following address:
Attention:North Carolina Division of Water Resources

A. (3.) DISCHARGE ALTERNATIVES EVALUATION
In an effort to comply with North Carolina Water Quality Standards (WQS) for the following
parameters: chloride, manganese, lead, and total dissolved solids; the Permittee shall
assess potential discharge alternatives. It is recommended that the evaluation thoroughly
assess 3 to 4 of the following alternatives:
1. Connect discharge to a WWTP: Determine whether the wastewater can be discharged
to a Wastewater Treatment Plant (WWTP) or pumped and hauled to a
WWTP. Approval or disapproval from the municipality should be
acquired.
2. Obtain a Non -discharge permit: Eliminate the surface water discharge by obtaining a
non -discharge permit for spray irrigation, infiltration, or subsurface
disposal (on -site drainfield, infiltration gallery, injection wells).
3. Install Wastewater Treatment: Install improved wastewater treatment to enable the
facility effluent to consistently comply with Water Quality Standards.
If this is not technically feasible or cost prohibitive, please explain and
provide estimated costs.
4. Use Alternative Water Source: Obtain drinking water from another source (nearest
County, City, or Town or other wells) so either the discharge is
eliminated or compliance with WQS's is achieved.
S. Use Alternative Water Treatment Method: Install alternative and/or innovative water
treatment methods or operational improvements that do not produce
noncompliant wastewaters. For example, installing a recycle
iron/manganese filtration system with no discharge.
6. Discharge to a Larger stream: Relocate the facility's discharge to a larger receiving
stream and determine if limits can be achieved given the increased
dilution.
7. Combination of Alternatives: Employ any combination of the alternatives listed above
that would result in achieving compliance with Water Quality
Standards.
The evaluation shall include a present value of costs analysis for all technologically feasible
options as outlined in the Division's "Engineering Alternatives Analysis Guidance
Document." This Document can be found at:
httR:ILportal.ncdenr.org/web/wq/swp/ps/npdes/­permits-
This evaluation is being requested to determine whether there are any economical and
technologically feasible alternatives available to the Permittee to comply with NC Water
Quality Standards. -If one or two discharge alternatives are available to the Permittee,
please identify the preferred alternative and an estimated timeline for implementation. The
Permittee shall submit the Discharge Alternatives Evaluation to the Division at the address
listed below four years after the effective date of this permit (by October 2, 2017).

Facility Classification PC-1
Dear Mr. Konsul:
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued pursuant
to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement
between North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007 (or as
subsequently amended).
Thank you for your expedited response to my email dated August 12, 2013. Regarding your two
comments made on the final permit the Division offers the following responses. NPDES understands
that a discharge from Ion Exchange backwash is not always predictable. As a result, many Ion
Exchange WTPs choose to initiate a manual backwash and proceed to collect aliquot samples at spaced
intervals to obtain a representative sample. Some Ion Exchange WTPs have chosen to install composite
samplers to decrease the operator responsibilities but this can be costly. NPDES appreciates your
efforts to schedule sampling visits to coincide with expected backwashing or to manually place the
softeners into backwash mode in order to collect a sample. The Division does find this practice to be
acceptable. Note that a representative sample is considered to be the wastewater being discharged and
not the static wastewater in the holding tank.
Regarding your comment on turbidity sampling, please note that in a letter dated Feb. 25, 2009 from
EPA Region IV the state is obligated to put turbidity monitoring in the NPDES permit. This also

satisfies testing regulations cited in NC Administrative Code 15A 2$ .0500. It is recommended that the
test be performed using a turbidity meter.
All the changes made in this permit renewal as compared to the current permit are as follows:
• The receiving waterbody is not listed as Nutrient Sensitive Waters and the maximum discharge
flow is less than 0.05 MGD. Therefore, per the Water Treatment Plant Strategy, Total
Phosphorus and Total Nitrogen monitoring have been removed from the permit.
• Ammonia- nitrogen monitoring was removed from the permit since sampling results did not
show significant concentration levels of ammonia -nitrogen in the effluent. '
• Flow monitoring has been increased to twice a month and a footnote was added to the permit
stating that flow shall be measured the same date samples are collected for analysis. If an
instantaneous sample is collected the duration of the discharge event shall be recorded in a log
book and available for inspection.
• Monthly Turbidity monitoring has been added to the permit in accordance with a letter received
from EPA Region IV dated Feb. 25, 2009 and in accordance with Administrative Code Section
I SA NCAC 213.0500.
• Footnote number 3 was amended under Section A (1) to include the following statement: TRC
limit and monitoring requirement only apply if chlorine is used for disinfection. The Permittee
shall report all effluent TRC values reported by a NC -certified laboratory [including field -
certified]. Effluent values below 50 µg/L will be treated as zero for compliance purposes.
• The wording in Section A. (2.) has been changed and the following paragraph added: If the
Permittee monitors any pollutant more frequently than required by this permit, the results of such
monitoring shall be included in the calculation and reporting of the data submitted on the
Discharge Monitoring Report and all AT Forms submitted. .
• Copper, zinc, and iron effluent samples reported from May 2008 through June 2011 showed
reasonable potential to violate North Carolina Water Quality Standards. Since copper, zinc, and
iron have Action Level standards and should be reviewed in conjunction with quarterly toxicity
testing, it is recommended that monitoring for these parameters remain in the NPDES permit at a
reduced monitoring frequency of quarterly. It is anticipated, that discharge alternatives assessed as
part of the Discharge Alternatives Evaluation, will likely eliminate toxicity, failures in the effluent
as well.
• Effluent sampling data evaluated from May 2008 to June 2011 for lead, manganese, chloride,
and total dissolved solids showed reasonable potential to violate North Carolina Water Quality
Standards for all these parameters.

Carolina Water Services ability to comply with these standards will require an investigation of
potential discharge alternatives. This assessment is outlined in a special condition in Section
A.(3) Discharge Alternatives Evaluation. The evaluation findings are to be submitted to the
Division within four years of the effective date of this permit and the findings will be used in
drafting the next permit renewal. The Division recognizes that determining both how to comply

Page 3 of 3
with WQS's and provide residents with safe, acceptable and clean drinking water is a complex
issue. This evaluation is being requested to determine whether there are any economical and
technologically feasible alternatives available to the Permittee to comply with NC Water
Quality Standards.
• The wording in Section A.(3) Discharge Alternatives Evaluation was modified as compared
to the wording in the email sent on August 12, 2013. Changes were requested in an effort to
more clearly state the objective of the Discharge Alternatives Evaluation. Please review it
carefully.
• Section A. (4.) Alternatives Evaluation Re -opener was added to the permit to identify to the
Permittee that the Division may re -open this permit to include the findings from the Discharge
Alternatives Evaluation in the form of a compliance schedule.
• The Supplement to Cover was corrected as requested.
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty
(30) days following receipt of this letter. This request must be in the form of a written petition,
conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of
Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-6714). Unless
such demand is made, this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may
require modification or revocation and reissuance of the permit. This permit does not affect the legal
requirements to obtain other permits which may be required by the Division of Water Resources or
permits required by the Division of Land Resources, the Coastal Area Management Act or any other
Federal or Local governmental permit that may be required.

State of North Carolina and having a mailing address of Post Office Box 240908, Charlotte, North
Carolina, 28224-0908, hereinafter referred to as "CWSNC" and the TOWN OF
MOORESVILLE, a North Carolina Municipal Corporation, having a mailing address of P.O. Box
878, Mooresville, North Carolina, 28115, hereinafter referred to as "Mooresville".
VJ TNMETH:
WHEREAS, Mooresville currently owns a water distribution system which lies within
Iredell County, North Carolina, and which includes water treatment plants located in the Town of
Mooresville, with such plants being collectively referred to herein as the "Mooresville Plant;" and
WHEREAS, Mooresville is engaged in the business of operating, maintaining, and
managing a public water utility; and
WHEREAS, Mooresville and CWSNC mutually desire to enter into an agreement to
provide for the sale of water to CWSNC; and
WHEREAS, the Town Board of Mooresville has determined that Mooresville has the
present capacity to sell such water to CWSNC.
NOW, THEREFORE, in consideration of the mutual covenants, conditions and terms
contained herein, the parties hereto, intending to be legally bound hereby, agree as follows:
1. REPRESENTATIONS, TERMS AND CONDITIONS
a. CWSNC is a privately owned business, incorporated and licensed to do business in
North Carolina. The nature of its business is supplying water and/or sanitary sewer
services to residents outside the jurisdiction of the Town of Mooresville, North
Carolina. CWSNC has the requisite power and authority to enter into this Agreement,
and the signatories hereto have been authorized to execute the documents necessary on
behalf of CWSNC under the terms of its By-laws and as authorized by its corporate
charter and by its Board of Directors.

c. CWSNC and Mooresville each have among their powers the authority to contract with
one another to perform such undertaking as described in this Agreement.
d. Entry into this Agreement by either party will not violate any applicable law, judgment,

agreement or instrument by which either of the entities is bound.
Page I of 9

e. CWSNC and Mooresville each has or holds, and will continue to have or hold
through the date of transfer and closing, all appropriate permits necessary to effectuate
their respective responsibilities under this Agreement or will use their best efforts to
obtain such permits.
2. INDEBTEDNESS AND REVENUE
a. To CWSNC's knowledge, there are no claims, suits, or actions pending or judgments
entered which, if successful, would create an encumbrance upon its revenues which
would have a priority over Mooresville's entitlement to payment pursuant to the terms
of this agreement or which otherwise would have a material adverse effect on the
ability of either CWSNC or Mooresville to perform their obligations hereunder.
b. No litigation is pending or threatened against CWSNC which would impair its ability
to perform its duties and obligations under this Agreement.
c. No litigation is pending or threatened against Mooresville which would impair its
ability to perform its duties and obligations under this Agreement.
EFFECTIVE DATE AND TERM
a. The term of this Agreement shall commence on the date that CWSNC begins to
receive water from Town (the "Effective Date") and unless earlier terminated in accordance
with the terms hereof, shall expire at midnight on the same date in the year 2033. The
provisions of this Agreement may thereafter be extended by written notice from CWSNC
to the Town of Mooresville for an additional five (5) year term under the same terms and
conditions as contained herein unless at least one -hundred eighty (180) days prior to the
expiration of this Agreement, even if written notice from CWSNC has already been given,
Town gives written notice to CWSNC that Town does not desire to extend such
Agreement.
4. PURCHASE OF WATER SERVICES
a. Mooresville does hereby grant, bargain, sell, convey, and agree to provide water to
CWSNC and CWSNC agrees to purchase such water from Mooresville in a minimum
amount 30,000 gallons per day and a maximum amount not to exceed 656,000 gallons
per day. It is understood and agreed that should CWSNC desire to purchase on any
given day less than 30,000 gallons of water, CWSNC will pay the costs of 30,000
gallons of water for that day even if the amount of gallons obtained on such day is less
than 30,000 gallons. Water will be charged in 1,000 gallon increments. CWSNC
agrees that it is CWSNC's sole responsibility to manage and control the capacity
purchased under this agreement.
b. CWSNC agrees to pay any capacity fees as established by Town based on an eight inch
(8") meter in order for CWSNC to obtain such water with such fees to be based on
the-Town's then current system development and availability fees.
c. In exchange for such water, CWSNC agrees to pay Mooresville the adopted utility bulk
rate at the time that CWSNC connects to Mooresville and begins obtaining water
from Mooresville. The flow shall be the flow as measured by a meter, or meters,
installed at a location, or locations, as agreed upon by both and Mooresville. Such
rate shall be subject to review and adjustment thereafter on an annual basis,
PROVIDED, that at no time shall CWSNC pay a rate higher than the rate paid by any
other commercial reseller of water services provided by the Town of Mooresville
Pursuant to an agreement entered into between Mooresville and any other party on or
after the date of this Agreement.
101

d. No increase in the rate shall be charged to CWSNC unless it is also charged to other
commercial resellers of water services provided by the Town of Mooresville pursuant to
an agreement entered into between Mooresville and any other party and no increase
shall be greater than the percentage increase charged to other commercial resellers of
water services. Any percentage increase in the rate charged to CWSNC shall not be
greater than the percentage increase in the rate charged to customers inside the
corporate limits of the Town of Mooresville.
e. CWSNC further agrees that it will at all times charge its water consumers the rates as
approved by the North Carolina Utilities Commission (the "Commission"). The
Town will not oppose efforts by CWSNC to obtain approval from the Commission for
pawthrough of rates and fees charged by the Town.
f. CWSNC shall provide and install at its own cost and expense, metering devices with
shutoff devices, backflow prevention assemblies, and other such devices as Mooresville
determines is necessary for the purpose of measuring the quantity of water supplied
pursuant to this agreement. Said metering device shall not exceed eight (8) inches in
size unless a larger meter is required because of increased demand or usage.
Mooresville will be the sole owner of any meter once installed and ready for use.
Mooresville will secure the necessary calibration of any such meters at the time of
installation and as deemed necessary by Mooresville. Upon the specific request of
CWSNC, Mooresville will schedule certification of the metering device(s) by a certified
testing and calibration firm and will give such advance notification as is reasonable
under the circumstances. In the event such certification indicates that the meter is not
accurate within AWWA standards for the metering device installed, Mooresville will
pay for the certification. In the event the metering device is determined to be accurate
within the AWWA established standards then CWSNC shall pay for the certification
g. Any meters installed that are subject to this Agreement shall be installed at a location
suitable to Mooresville. CWSNC agrees to allow such meters to be installed on its
property or if necessary, to acquire any agreements acceptable to Town for their
installation on property not owned or controlled by CWSNC.
h. It is further agreed that if, at any time, a meter shall fail to correctly register the
quantity of water flowing through such meter, such amounts shall be determined by
taking the average of the twelve readings immediately preceding the failure of such
meter. Should the failure occur within the first twelve months of this agreement, and
the service has less than twelve readings, such average may be based on the largest
possible number less than twelve excluding any reading that is a result of such average.
i. Nothing in this agreement shall imply or create any ownership rights or responsibilities
by CWSNC in any water system or water treatment facilities, but conveys only the
purchase of water at the rates established herein, or as the same may be hereafter
modified pursuant to the terms of this Agreement. Mooresville shall at all times
remain the Owner and Operator of the Mooresville Treatment Plants and Water
Distribution System.
j. It is agreed that all policies concerning payment and disconnection from service for
nonpayment of water shall apply to CWSNC as it does for any other commercial or
noncommercial customer of Mooresville.
5. ADDITIONS, EXTENSIONS OR CONNECTIONS TO THE WATER DISTRIBUTION
SYSTEM
a. It is understood that the Town of Mooresville may have the statutory right to annex
the area, or parts thereof, that are currently serviced by CWSNC or even to customers
3

being served by CWSNC and that residents in such area may request water services
from Town. To this end, and should such annexation occur or request for services be
granted, Town may provide such water services without penalty or payment to
CWSNC and such provision of services will not be considered a material breach of this
agreement.
b. It is understood and agreed that CWSNC is solely responsible for its lines, pipes,
meters, or any equipment or materials that are located on its side of the water meter as
set out above.
c. If at any time during the term of this agreement insufficient capacity exists in the
Mooresville Plant to serve CWSNC's customers above that minimum capacity defined
in Section 4a. of this agreement, then the maximum capacity as defined in Section 4a
shall be reduced proportionality as such capacity is reduced in the Mooresville Plant.
6. APPLICATION OF POLICIES
a. It is agreed by CWSNC that it will be subject to all Town of Mooresville policies,
ordinances, directives, statutes, regulations, or guidelines related to conservation of
water.
b. Pursuant to that Order dated May 23, 2008, by the Commission regarding Docket
Numbers W 100, SUB 46 and WR-100, SUB 6, CWSNC agrees that it is, and
will be, subject to the same water restrictions that may be imposed by the Town
pursuant to any ordinances, rules, regulations, guidelines, or other criteria that
may be implemented by the Town concerning nonessential water usage
restrictions.
C. It is agreed by CWSNC that any penalties levied for violation of any policies,
ordinances, directives, statutes, regulations, or guidelines shall be the sole
responsibility of CWSNC.
d. Without waiving the minimum amount of fees to be paid by CWSNC under
Section 4.a. herein, it is understood and therefore agreed that should at any time
CWSNC close the valve (or, in the alternative, the tap) connecting it to the Town's
water system and it is no longer receiving any amount of water from Town but
instead is making use of its own water resources, this Section 6 shall not apply.
7. CAPACITY TO SERVE
In the event that an emergency situation prevents Town from having an adequate supply of
water necessary for Town to meet its obligations under the terms of this Agreement, the Town shall
immediately give CWSNC notice of such emergency. Under such circumstances, Town shall be
relieved from supplying water under this Agreement and CWSNC shall be relieved from making
the minimum payment under Section 4a until such time as CWSNC begins to receive water under
the terms of this Agreement. And, it is further agreed that in the event of such disruption of
service, CWSNC agrees to hold Town harmless from any and all damages or harms resulting from
such disruption of service except damages or harms arising from the Town's gross negligence or
intentional misconduct.
8. RIGHTS AND OBLIGATIONS OF CWSNC
CWSNC shall, at its own cost and expense, construct, or cause to be constructed the
necessary water distribution system, including, but not limited to waterlines, water booster pump
stations, and storage facilities, necessary to transport water to its customers from the existing
Mooresville water distribution system. The proposed water infrastructure shall connect to the
4

existing Town of Mooresville water system as shown on Exhibit 1 attached hereto and incorporated
herein.
9. EMERGENCY SITUATIONS
a. Each Party to this agreement shall notify the other within twenty-four (24) hours of any
activity, problem, or circumstance it should reasonably become aware of which
threatens the safety, health or welfare of the users of the water distribution system or
the surrounding environment as soon as is reasonably possible.
b. Mooresville's response to emergencies and unusual circumstances shall be in
accordance with applicable policies, regulations, and requirements and with such
personnel and equipment as necessary to maintain or restore the operations in a timely
manner with the least possible disruption or inconvenience to CWSNC or its
customers served under the terms of this agreement.

Q 7 The Ecoflow is a Catalytic Water Conditioner, is a new innovation in water conditioning. The Ecoflow
Water Conditioner is, as the name suggests, a "water conditioner", not a "softener" nor a "filter". The foundation of the Ecoflow is the
scale controlling media, made from ceramic -metallic materials.
Within the Ecoflow a three phase conditioning process is achieved:
L. Polarization: In the first stage, water passes into the unit through flow modulators that polarize the water stream along with the
materials contained within it. This action formats the water so that the following process can impact the water stream more completely.
Documentation 2. Oxidation Reduction (Redox Process): The propensity and ability for water to scale and harden through oxidation is reduced as
water flows over the Nano -Technology developed Ceramic Media that contains a matrix of minerals and rare earth elements.
3. Ionization: As the water stream passes over the Ceramic Media, the electron fields of the materials within the water stream overlap
with the electron fields of the materials contained within the Ceramic Media. The exchange of ions is encouraged and enhanced. The
turbulent water flow through these materials creates a self -generating Piezo-Static-Electric charge that aids the entire process.
The Ecoflow Water Conditioner has many positive Benefits in various industries:
• Reduce and Prevent Scale Formation.
• Inhibit Hard Water Corrosion.
• Increases Soil Permeability.
• Reduction in Chloride Levels in soil growth layers
• Reduction in Water Usage.
• Extends the Lifespan on all Water Related Equipment e.g., Cooling Towers, Heating and Hot Water Systems, Water Pumping
and Supply Systems etc.
The Ecoflow Water Conditioner can reduce, eliminate or improve water related problems that can impact homes, farms and businesses
without using salts, chemicals, electricity and maintenance. The Ecoflow Water Conditioner comes with a 5 Year Limited Warranty
against Defects in Materials and Craftsmanship when used under normal conditions which intended, offers peace of mind on your
investment into your personal property or business.
The Ecoflow has a wide range of Applications for many Industries which can benefit from improved water conditioning such as but
not limited to the following examples:

Ultra -Efficient Wastewater Evaporators and Crystallizers
> Recover and reuse wastewater volumes by up to 99%
X-Series
Engineered to be the most efficient wastewater evaporators
and crystallizers on the market, Slipstream's X-Series offers in-
dustrial waste generators an elegant and simple solution to a
complex problem.
The X-Series platform utilizes world -class, patent -pending tech-
nology to deliver wastewater crystallization at a fraction of the
cost for competing technologies. With operating efficiencies
up to 6 times better than conventional evaporators,
wastewater can be completely eliminated from the equation
for energy costs of less than $0.01 per gallon.
The X-Series is also closed -loop so there is no atmospheric
emission and no sewer discharge which greatly reduces the
regulatory requirements imposed on many industrial
wastewater generators.
Constructed of super corrosion resistant 316L SS or Titanium
and mounted within an epoxy coated steel frame, these units
are engineered to withstand the most demanding of condi-
tions. Additionally, Slipstream's vast experience in wastewater
treatment has allowed us to design a PLC -driven control sys-
tem that dramatically reduces the need for an operator. Sim-
ple Start/Stop commands and fully automated control, cou-
pled with ancillary components selected for their proven relia-
bility, ensure a robust unit that requires minimal oversight and
even less maintenance.

The Harbour — Wells #1 and #2 WTP
Iredell County
Facility Classification PC-1
Dear Mr. Konsul:
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued pursuant
to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement
between North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007 (or as
subsequently amended).
Thank you for your expedited response to my email dated August 12, 2013. Regarding your two
comments made on the final permit the Division offers the following responses. NPDES understands
that a discharge from Ion Exchange backwash is not always predictable. As a result, many Ion
Exchange WTPs choose to initiate a manual backwash and proceed to collect aliquot samples at spaced
intervals to obtain a representative sample. Some Ion Exchange WTPs have chosen to install composite
samplers to decrease the operator responsibilities but this can be costly. NPDES appreciates your
efforts to schedule sampling visits to coincide with expected backwashing or to manually place the
softeners into backwash mode in order to collect a sample. The Division does find this practice to be
acceptable. Note that a representative sample is considered to be the wastewater being discharged and
not the static wastewater in the holding tank.
Regarding your comment on turbidity sampling, please note that in a letter dated Feb. 25, 2009 from
EPA Region IV the state is obligated to put turbidity monitoring in the NPDES permit. This also

satisfies testing regulations cited in NC Administrative Code 15A 2B .0500. It is recommended that the
test be performed using a turbidity meter.
All the changes made in this permit renewal as compared to the current permit are as follows:
• The receiving waterbody is not listed as Nutrient Sensitive Waters and the maximum discharge
flow is less than 0.05 MGD. Therefore, per the Water Treatment Plant Strategy, Total
Phosphorus and Total Nitrogen monitoring have been removed from the permit.
• Ammonia- nitrogen monitoring was removed from the permit since sampling results did not
show significant concentration levels of ammonia -nitrogen in the effluent.
• Flow monitoring has been increased to twice a month and a footnote was added to the permit
stating that flow shall be measured the same date samples are collected for analysis. If an
instantaneous sample is collected the duration of the discharge event shall be recorded in a log
book and available for inspection.
• Monthly Turbidity monitoring has been added to the permit in accordance with a letter received
from EPA Region IV dated Feb. 25, 2009 and in accordance with Administrative Code Section
15A NCAC 213.0500.
• Footnote number 3 was amended under Section A (L) to include the following statement: TRC
limit and monitoring requirement only apply if chlorine is used for disinfection. The Permittee
shall report all effluent TRC values reported by a NC -certified laboratory [including fleld-
certified]. Effluent values below 50 µg/L will be treated as zero for compliance purposes.
• The wording in Section A. (2.) has been changed and the following paragraph added: If the
Permittee monitors any pollutant more frequently than required by this permit, the results of such
monitoring shall be included in the calculation and reporting of the data submitted on the
Discharge Monitoring Report and all AT Forms submitted. .
• Copper, zinc, and iron effluent samples reported from May 2008 through June 2011 showed
reasonable potential to violate North Carolina Water Quality Standards. Since copper, zinc, and
iron have Action Level standards and should be reviewed in conjunction with quarterly toxicity
testing, it is recommended that monitoring for these parameters remain in the NPDES permit at
a reduced monitoring frequency of quarterly. It is anticipated, that discharge alternatives
assessed as part of the Discharge Alternatives Evaluation, will likely eliminate toxicity failures
in the effluent as well.
• Effluent sampling data evaluated from May 2008 to June 2011 for lead, manganese, chloride,
and total dissolved solids showed reasonable potential to violate North Carolina Water Quality
Standards for all these parameters.

Carolina Water Services ability to comply with these standards will require an investigation of
potential discharge alternatives. This assessment is outlined in a special condition in Section
A.(3) Discharge Alternatives Evaluation. The evaluation findings are to be submitted to the
Division within four years of the effective date of this permit and the findings will be used in
drafting the next permit renewal. The Division recognizes that determining both how to comply

Page 3 of 3
with WQS's and provide residents with safe, acceptable and clean drinking water is a complex
issue. This evaluation is being requested to determine whether there are any economical and
technologically feasible alternatives available to the Permittee to comply with NC Water
Quality Standards.
• The wording in Section A.(3) Discharge Alternatives Evaluation was modified as compared
to the wording in the email sent on August 12, 2013. Changes were requested in an effort to
more clearly state the objective of the Discharge Alternatives Evaluation. Please review it
carefully.
• Section A. (4.) Alternatives Evaluation Re -opener was added to the permit to identify to the
Permittee that the Division may re -open this permit to include the findings from the Discharge
Alternatives Evaluation in the form of a compliance schedule.
• The Supplement to Cover was corrected as requested.
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty
(30) days following receipt of this letter. This request must be in the form of a written petition,
conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of
Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-6714). Unless
such demand is made, this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may
require modification or revocation and reissuance of the permit. This permit does not affect the legal
requirements to obtain other permits which may be required by the Division of Water Resources or
permits required by the Division of Land Resources, the Coastal Area Management Act or any other
Federal or Local governmental permit that may be required.
If you have any questions concerning this permit, please contact Julie Grzyb by email

Permit NCO084565
A. (2.) CHRONIC TOXICITY PASS/FAIL MONITORING (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 90 %.
The testing shall be performed as a Ceriodaphnia dubia 7-day pass/fail test. The tests will
be performed during the months of March, June, September, and December. 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, DWQ Form AT-1 (original) is to be sent to the
following address:
Attention: North Carolina Division of Water Resources
Environmental Sciences Section
1621 Mail Service Center
Raleigh, N.C. 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental 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 Environmental 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.
If the Permittee monitors any pollutant more frequently than 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.

i A. (3.) DISCHARGE ALTERNATIVES EVALUATION
In an effort to comply with North Carolina Water Quality Standards (WQS) for the following
parameters: chloride, manganese, lead, and total dissolved solids; the Permittee shall
assess potential discharge alternatives. It is recommended that the evaluation thoroughly
assess 3 to 4 of the following alternatives:
1. Connect discharge to a WWTP: Determine whether the wastewater can be discharged
to a Wastewater Treatment Plant (WWTP) or pumped and hauled to a'
WWTP. Approval or disapproval from the municipality should be
acquired.
2. Obtain a Non -discharge permit: Eliminate the surface water discharge by obtaining a
non -discharge permit for spray irrigation, infiltration, or subsurface
disposal (on -site drainfield, infiltration gallery, injection wells).
3. Install Wastewater Treatment: Install improved wastewater treatment to enable the
facility effluent to consistently comply with Water Quality Standards.
If this is not technically feasible or cost prohibitive, please explain and
provide estimated costs.
4. Use Alternative Water Source: Obtain drinking water from another source (nearest
County, City, or Town or other wells) so either the discharge is
eliminated or compliance with WQS's is achieved.
5. Use Alternative Water Treatment Method: Install alternative and/or innovative water
treatment methods or operational improvements that do not produce
noncompliant wastewaters. For example, installing a recycle
iron/manganese filtration system with no discharge.
6. Discharge to a Larger stream: Relocate the facility's�discharge to a larger receiving
stream and determine if limits can be achieved given the increased
dilution.
7. Combination of Alternatives: Employ any combination of the alternatives listed above
that would result in achieving compliance with Water Quality
Standards.
The evaluation shall include a present value of costs analysis for all technologically feasible
options as outlined in the Division's "Engineering Alternatives Analysis Guidance
Document." This Document can be found at:
http://portal.ncdenr.org/web/wq/swp/ps/­­npdes/­permits.
This evaluation is being requested to determine whether there are any economical and
technologically feasible alternatives available to the Permittee to comply with NC Water
Quality Standards. If one or two discharge alternatives are available to the Permittee,
please identify the preferred alternative and an estimated timeline for implementation. The
Permittee shall submit the Discharge Alternatives Evaluation to the Division at the address
listed below four years after the effective date of this permit (by October 2, 2017).

BIMS Downloads and Renewal Review Summary:
• For renewal: Updated effluent page in accordance with Ion Exchange WTP technology guidelines (2009); updated permit
template, facility location, facility description, and added 8 Digit HUC to the map; Added parameter monitoring and limits
based on zero flow conditions (IWC=100%) using Reasonable Potential Analysis. DMR's from August 2008 — June 2011
reported a maximum flow of 0.058 MGD and an average flow of 0.002 MGD. The maximum, monthly average flow from
0 1-20 10 through 12-2012 was 0.0091 MGD which was used in the RPA analysis per WTP Strategy.
• Flow Monitoring — Reviewed flow data and in accordance with the WTP Strategy revised the monitoring frequency for flow
to twice monthly, which is as frequent as the minimum frequency of monitoring for any parameter listed. Included a footnote
that the facility is to record and report flow the date of sampling.
• Toxici - The facility has failed 19 out of 22 toxicity tests in the past 5 years. Permit requires the facility to conduct quarterly
toxicity monitoring in conjunction with the sampling of manganese, zinc, iron, copper, and lead.
• Compliance Record — The BIMs records indicate the facility has one penalty assessment LV-2009-0045 for TSS daily
maximum exceeded and one TSS monthly maximum exceeded resulting from DMR data collected in October 2008.
• Effluent data — indicates the current discharge treatment may not be adequate to meet the North Carolina Water Quality
Standards for total dissolved solids, manganese, chloride, and lead.
• TRC —IWC calculation completed for TRC using S7Q10 (CFS) =zero and a maximum, monthly average flow of 0.009 MGD

Permit NCO084565
Reasonable Potential Analysis —Reasonable potential to violate water quality standards were shown for copper, zinc, lead,
iron, chloride, total dissolved solids, and manganese. Since copper, zinc, and iron have action level standards and should be
reviewed in conjunction with toxicity testing it is recommended that monitoring for these parameters remain in the NPDES
permit at a measurement frequency of quarterly. The original draft permit contained limitations for water supply water
quality standards for chloride, total dissolved solids, and manganese and aquatic life water quality standards for lead. After
comments were received from CWS's (Utilities Inc.) the limitations were removed and special condition A.(3.) Discharge
Alternatives Evaluation was modified.

• A special condition in Section A.(3.) was added to the permit requiring the permittee to perform a Discharge Alternatives
Evaluation to determine how the facility can comply with the water quality standards listed above. This evaluation is to be
submitted to DWR/NPDES in four years so the findings can be discussed and inserted into the next permit renewal.
• Nutrient Monitoring — The water body is not subject to the NSW classification and since the maximum, monthly average
flow is less than 0.05 MGD (DMR data from August 2008 — June 2011) TN and TP were removed from the permit.
Proposed Changes:
• The discharge flow is less than 0.05 MGD and the receiving water body is not NSW, per the Water Treatment Plant Strategy,
Total Phosphorus and Total Nitrogen monitoring have been removed from the permit.
• Ammonia- nitrogen monitoring was removed from the permit since sampling results did not show toxic or significant
concentration levels of ammonia -nitrogen in the effluent.
• Flow monitoring has been increased to twice a month and a footnote was added to the permit stating that flow shall be
measured the same date samples are collected for analysis. If an instantaneous sample is collected the duration of the
discharge event shall be recorded in the log book.
• Monthly Turbidity monitoring has been added to the permit in accordance with a letter received from EPA Region IV dated
Feb. 25, 2009 and in accordance with Administrative Code Section 15A NCAC 2B .0500.
• Footnote number 3 was amended under Section A (L) to include the following statement: TRC limit and monitoring
requirement only apply if chlorine is used for disinfection. The Permittee shall report all effluent TRC values reported by a
NC -certified laboratory [including field -certified]. Effluent values below 50 µg/L will be treated as zero for compliance
purposes.
• Copper, zinc, and iron effluent samples reported from May 2008 through June 2011 showed reasonable potential to violate
North Carolina Water Quality Standards. Since copper, zinc, and iron have Action Level standards and should be reviewed in
conjunction with quarterly toxicity testing. Monitoring for these parameters remain in the NPDES permit at a reduced
monitoring frequency of quarterly.
• Effluent sampling data evaluated from May 2008 to June 2011 for Lead, Manganese, Chloride, and Total Dissolved Solids
showed reasonable potential to violate North Carolina Water Quality Standards for all these parameters.

Carolina Water Services ability to comply with these standards will require an investigation of potential discharge
alternatives. This assessment is outlined in Section A.(3) Discharge Alternatives Evaluation. The evaluation findings are to
be submitted to the Division within four years of the effective date of this permit and the findings will be used in drafting the
next permit renewal. The Division recognizes that determining both how to comply with WQS's and provide residents with
safe, acceptable and clean drinking water is a complex issue. This evaluation is being requested to determine whether there
are any economical and technologically feasible alternatives available to the Permittee to comply with NC Water Quality
Standards.
• Section A. (4.) Alternatives Evaluation Re -opener was added to the permit to identify to the Permittee that the Division
may re -open this permit to include the findings from the Discharge Alternatives Evaluation in the form of a compliance
schedule.
• The Supplement to Cover was corrected as requested.

REGIONAL OFFICE COMMENTS:
Comments were received from Britt Setzer, DWR/PWS Section on May 1, 2013,
Britt stated that 1) the discharge is intermittent, that it never reaches surface waters, and that except for summer months the discharge
is approximately 1,000 gallons 2 times per week; 2) that the infiltration of the discharge into the soil, doesn't appear to adversely
impact any of the wells in the system; 3) that there are no established drinking water standards for hardness which the ion exchange
system is designed to treat for; and 4) that to comply with the permit the facility may have to discontinue operation.
Britt stated that he understood CWS may be able to negotiate additional water purchases from the Town of Mooresville (TOM) in the
future, however, there appear to be no other viable alternatives' for CWS other than obtaining drinking water from TOM.

NCO084565
Julie,
We have reviewed the draft permit you have provided and your comments below. We do still have some feedback as
follows:
1) We really don't understand the validity or importance of the turbidity monitoring addition. It has never been
there in previous permits and seems to serve no real purpose and only increase costs. If you are required to
implement this testing, then so be it.
2) In regards to the condition "All samples must be collected from a typical discharge event", we need to
emphasize that this is virtually impossible to do and this has caused some controversy in the past. The
"discharge event" is created when the softener units backwash after a pre -calculated amount of raw water has
passed through the vessels thus allowing the softener to recharge before it has expended its capacity for
hardness removal. There is no way to ensure we are physically present when this happens. If we manually
place the softeners into backwash while we are there, it may not be truly representative but is as close as we
can get. We have also collected "static" samples from the holding tanks when there was no active flow as this
water in theory should be representative of the discharge quality but to actually have flow moving out the
discharge, we will have to place the units in manual backwash. We will try.and schedule our sampling visits to
coincide with expected backwashing but we would ask the division to understand the practical limitations of this
somewhat unusual situation.
We will be reaching out to the Aquatic toxicology unit at your suggestion to be sure we are doing everything as best we
can in regards to the chronic toxicity testing. In reading the "NC ... Toxicity Procedure" version 3 December 2010, the
test protocol is complicated and we want to ensure that both ourselves and testing lab are following the procedures.
Thanks again for your consideration.

Subject: RE: The Harbour The Point softener draft NPDES permits NC0086606, NCO086592 and NCO084565
Martin,

Thank you for your comment letter regarding the draft NPDES permits for The Harbour —Well #1 and #2 WTP, The Point
Well #1 WTP, and The Habour Well #4 WTP. In response to your letter the Division has made some revisions to the draft
permits. While the Division is responsible for implementing water quality standards adopted by the state, the Division
also recognizes the residents need for safe, acceptable and clean drinking water. A copy of the final permit that will be
issued to the WTP"s is attached (each final permit will be the same as the one attached except for the facility
name). Since these permits have already been public noticed there will not be another 30 day comment period.
However, since a number of revisions have been made, please review the attached permit carefully and respond with
any of your concerns by Aug. 201h. It is my hope that all the final WTP permits can be issued by the end of the month.
Changes made to each draft NPDES permit in response to Utilities, Inc's comment letter are summarized below:
As originally stated in the draft permits, Carolina Water Services, Inc. of NC, will investigate possible discharge
alternatives to comply with NC Water quality standards as discussed under special condition A.(3.). The time
period to perform the Discharge Alternatives Evaluation has been extended from three to a period of four years.
The final permit requires submittal of the Discharge Alternatives Evaluation to the Division, four years after the
effective date of the final permit. This timeframe will allow for the Division and CWS to meet and discuss the
evaluation findings prior to the issuance of the next permit. The purpose of the Discharge Alternatives
Evaluation is for the Permittee to document any economical and technologically feasible alternatives available
to the Permittee to comply with state Water Quality Standards. If one or two such alternatives are available to
the Permittee, please explain your preferred alternative and an estimated timeline for implementation. Special
Condition A.(3.) has been revised so please review the wording carefully.
• The permit limitations for total dissolved solids, total chloride, total manganese, and total lead were removed
from the permit and a special condition added that allows the Division to re -open the permit and insert a
schedule by which the Permittee will come into compliance with Water Quality Standards based on the
findings/results of the Discharge Alternatives Evaluation. See Special Condition A.(4).
• The requirement for up and downstream monitoring was removed from the permits based on DMR records
showing two of the facilities having no flow up or downstream of the discharge, for the past several years, and
one facility having a discharge to a storm drain. If this should change, stream monitoring requirements will be
modified accordingly.
• CWS has requested a five year delay in turbidity monitoring based on lab certification, however, laboratory
services throughout the state provide such testing for a reasonable fee ("$30.00). A five year delay does not
appear to be warranted.
• The Supplement to Cover was corrected as requested.
Please call or email me if you have any questions or would like to discuss any of the changes in detail. CWS will still have
the right to a adjudicatory hearing within thirty days of receipt of the final permit, however, I wanted to give CWS a
chance to look it over before moving forward and work together on any simple discrepancies, if possible.
Thanks,

Thank you for your comment letter regarding the draft NPDES permits for The Harbour —Well #1 and #2 WTP, The Point
Well #1 WTP, and The Habour Well #4 WTP. In response to your letter the Division has made some revisions to the draft
permits. While the Division is responsible for implementing water quality standards adopted by the state, the Division
also recognizes the residents need for safe, acceptable and clean drinking water. A copy of the final permit that will be
issued to the WTP"s is attached (each final permit will be the same as the one attached except for the facility
name). Since these permits have already been public noticed there will not be another 30 day comment period.
However, since a number of revisions have been made, please review the attached permit carefully and respond with
any of your concerns by Aug. 20`h. It is my hope that all the final WTP permits can be issued by the end of the month.
Changes made to each draft NPDES permit in response to Utilities, Inc's comment letter are summarized below:
As originally stated in the draft permits, Carolina Water Services, Inc. of NC, will investigate possible discharge
alternatives to comply with NC Water quality standards as discussed under special condition A.(3.). The time
period to perform the Discharge Alternatives Evaluation has been extended from three to a period of four years.
The final permit requires submittal of the Discharge Alternatives Evaluation to the Division, four years after the
effective date of the final permit. This timeframe will allow for the Division and CWS to meet and discuss the
evaluation findings prior to the issuance of the next permit. The purpose of the Discharge Alternatives
Evaluation is for the Permittee to document any economical and technologically feasible alternatives available
to the Permittee to comply with state Water Quality Standards. If one or two such alternatives are available to
the Permittee, please explain your preferred alternative and an estimated timeline for implementation. Special
Condition A.(3.) has been revised so please review the wording carefully.
• The permit limitations for total dissolved solids, total chloride, total manganese, and total lead were removed
from the permit and a special condition added that allows the Division to re -open the permit and insert a
schedule by which the Permittee will come into compliance with Water Quality Standards based on the
findings/results of the Discharge Alternatives Evaluation. See Special Condition A.(4).
• The requirement for up and downstream monitoring was removed from the permits based on DMR records
showing two of the facilities having no flow up or downstream of the discharge, for the past several years, and
one facility having a discharge to a storm drain. If this should change, stream monitoring requirements will be
modified accordingly.
• CWS has requested a five year delay in turbidity monitoring based on lab certification, however, laboratory
services throughout the state provide such testing for a reasonable fee (—$30.00). A five year delay does not
appear to be warranted.
0 The Supplement to Cover was corrected as requested.

Please call or email me if you have any questions or would like to discuss any of the changes in detail. CWS will still have
the right to a adjudicatory hearing within thirty days of receipt of the final permit, however, I wanted to give CWS a
chance to look it over before moving forward and work together on any simple discrepancies, if possible.
Thanks,
Julie Grzyb

A. (2.) CHRONIC TOXICITY PASS/FAIL MONITORING (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 90 %.
The testing shall be performed as a Ceriodaphnia dubia 7-day pass/fail test. The tests will
be performed during the months of March, June, September, and December. 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, DWQ Form AT-1 (original) is to be sent to the
following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, N.C. 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental 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 Environmental 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 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 than 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.

A. (3.) DISCHARGE ALTERNATIVES EVALUATION
In an effort to comply with North Carolina Water Quality Standards (WQS) for the following
parameters: chloride, manganese, lead, and total dissolved solids; the Permittee shall
assess possible discharge alternatives. It is recommended that the evaluation thoroughly
assess 3 to 4 of the following alternatives:
1. Install Wastewater Treatment: Installing improved wastewater treatment to enable the
facility to comply with Water Quality Standards.
2. Connect discharge to a POTW: This option shall assess if a Wastewater Treatment
Plant is nearby and if the facility is able to connect the discharge line
to the sewer or pump and haul wastewaters to the nearby POTW.
Approval or disapproval from the municipality should be acquired.
3. Obtain a Non -discharge permit: Disposal of wastewaters by obtaining a non -discharge
permit for spray irrigation, infiltration, or subsurface disposal (on -site
drainfield, infiltration gallery, injection wells).
4. Use Alternative Water treatment method or Source: Obtain drinking water from
another source (nearest County, City, or Town or other wells) so the
discharge is eliminated. Install alternative and/or innovative water
treatment methods or operational improvements that do not produce
noncompliant wastewaters. For example, installing a recycle
iron/manganese filtration system with no discharge.
S. Discharge to a Larger stream: Relocating the facility's discharge to a larger receiving
stream and determining if limits can be achieved given the increased
dilution.
6. Combination of Alternatives: Any combination of the alternatives listed above that
would result in achieving compliance with Water Quality Standards.
The evaluation shall include a present value of costs analysis for all technologically feasible
options as outlined in the Division's "Engineering Alternatives Analysis Guidance
Document." This Document can be found at:
htty://portal.ncdenr.org/web/wq/swp/-Ps/npdes/permits.
This evaluation is being requested to see if there are any economical and technologically
feasible alternatives available to the Permittee to comply with NC Water Quality Standards.
If one or two discharge alternatives are found to be practical, the Permittee should discuss
the preferred alternative and an estimated timeline for implementation. The Permittee
shall submit the Discharge Alternatives Evaluation to the Division at the address listed
below four years after the effective date of this permit.

Re: The Harbor and The Point NPDES Permits
NC0086606, NCO086592 and NCO084565
Dear Ms. Grzyb,
We are in receipt of the three above referenced draft permits and appreciate the Division's time in our meeting April
22 at the Regional office to discuss these permits and this situation.
As I hope we have conveyed, this is a challenging situation. The potable water softeners at these locations were
installed to provide treatment for hardness removal for customer satisfaction. NC DWR, Public Water Supply
Section approved the softener additions and supports these treatment facilities for the customers' benefit. By
addressing one issue, we created another. Conventional ion -exchange technology requires a backwash with a brine
solution and since there is no public sewer in the area, there were no alternatives to a point source discharge. The
only option to a discharge is to pump and haul (which would be economically prohibitive and impractical) or to shut
down the softener operations completely which would create sigmficant customer dissatisfaction. We do not feel
that these stricter permits or the actions we will be forced to take to comply are serving to meet the Division's
mission of protecting and enhancing North Carolina's surface water and groundwater resources for the citizens of
North Carolina. Therefore we are opposed to the draft permits. We realize that the Division issued the permits
initially based on then available information, however, by the fact that the permits were issued, a significant
investment was made to the addition of potable water treatment in the system and this will essentially be lost.
We request a reconsideration to allow the permits' original limits be "grandfathered" in and to remain as is.
If the Division is unable or unwilling to accommodate this request, the following are some issues we ask to be
specifically addressed;
• Turbidity parameter has been added to all of the permits. This will require purchase of turbidity meter(s) to
analyze this parameter and will also require a modification to our current field laboratory certification. We
do not agree this parameter addition is warranted. If its inclusion is required, we ask that it also be delayed
and not go into effect for five years.

• Upstream and downstream sampling should be removed and is inapplicable. Previous permits had this
removed. The Point system discharges to a storm drain and it is not possible to sample upstream or
downstream — even if there were flow. The Harbor Well 1 & 2 and well 4 facilities both discharge to ditches
and there is no stream.
• On page (4) Supplement to permit cover page — item (1) should state sodium metabisulfite (not metasulfite).

Subject: Review of Draft NPDES Permits
Permit NCO084565 — The Harbour — Wells #1 and #2 Water Treatment Plant
Permit NCO086592 — The Point Well #1 Water Treatment Plant
Permit NCO086606 — The Harbour Well #4 Water Treatment Plant
I have completed the review of the draft permits listed above. My comments and concerns are listed
below.
All of the water treatment plants identified in the draft permits have existed since the mid to late 1990S
without, to my knowledge, any obvious documented adverse impacts to the surface waters associated
with the discharges. The MRO DWQ staff is not aware of any complaints or concerns associated with the
current discharges.
Because these discharges are into unnamed tributaries to the Catawba River Basin, it appears that most
of the discharges never reach the surface waters (0 flow streams). The discharges are intermittent in
nature and only occur during a back wash cycle. My understanding is that the largest treatment plant
discharges approximately 1,000 gallons no more often than two times per week during normal operations.
Of course, the discharge amounts increase during peak demands in the summer months. This is by no
means a continual discharge which is typical with most NPDES permits. Furthermore, based on the
compliance water quality monitoring required under Section .1500 of the Rules Governing Public Water
Systems (RGPWS), it doesn't appear the infiltration of the discharges into the soil has adversely impacted
any of the wells at this system.
These discharges were permitted by the DWQ at the time of construction in the mid and late 1990s. I am
concerned the compliance schedule and alternatives evaluation presented in the draft permit may result
in the discontinuation of the water softening treatment units. There are no established drinking water
standards for hardness in North Carolina that would prevent Carolina Water Services (CWS) from ceasing
operations of these treatment units.

These water treatment facilities were approved by the PWS Section as listed below. These softening
units were approved primarily to deal with the hard water.
1. 1995 —Harbour Wells 1+2 — DEH Approval Serial Number — 95-08539
2. 1998 —The Pointe Wells 6-10 — DEH Approval Serial Number— 98-01048
3. 1999 —The Harbour Well #4 — DEH Approval Serial Number — 98-01757. This treatment plant
removes hardness associated with wells 4, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23 and 24.
Without these water softening systems, the consumer acceptability of the water would be extremely low
and result in significant customer complaints. This system can't function without these wells and meet
pressure and system demands.
The draft permit gives CWS three years to evaluate alternatives and make a proposal as to how to
resolve these water quality violations. The alternatives presented included the items listed below.
1. Disposal of wastewaters by such alternatives as connecting to a local WWTP, pump and hauling
wastewaters away, obtaining a non -discharge permit for land application or reuse.
2. Obtaining drinking water from another source.
3. Installing alternative water treatment methods.
4. Relocating the facility's discharge directly to the lake using a diffuser, assessing the model
dilution, and determining if the limits can be met at the predicted effluent dilution concentrations.
5. Installing a wastewater treatment to comply with the limits.
6. The permittee can assess any alterative which enables the facility to comply with the NC Water
Quality Standards.
At five years, CWS is required to comply with water quality standards specified in the draft permit as listed
below.
1. TDS - 500 mg/I
2. Total Chloride - 250 mg/I
3. Total Manganese — 200 ug/I
4. Total Lead — 25 ug/I
As was reported in your e-mail message, sampling data collected by CWS during the past four years
indicates maximum levels for the three treatment plants as listed below which is above the discharge
limits.
1. The Point — 26,000 ug/I — TDS, 27,840 mg/I — Total Chloride, 6700 ug/I — Total Manganese, 28
ug/I — Total Lead.
2. Harbour Well #4 — 48,000 mg/I — TDS, 19,000 mg/I — Total Chloride, 6500 ug/I — Total
Manganese, 38 ug/I — Total Lead.
3. Harbour Wells #1 and #2 — 23,000 mg/I — TDS, 14,000 mg/I — Total Chloride, 6500 ug/I — Total
Manganese, 79 ug/I — Total Lead.
On April 22, 2013, CWS met with the DWQ staff and me to discuss the draft NPDES permit and proposed
alternatives identified in the draft permit. It appears the only viable alternative to resolve the water quality
violations is to obtain supplemental water supply from the Town of Mooresville (TOM). According to CWS,
a contractual agreement has been executed between the TOM and CWS to allow for a purchase of
approximately 646,000 gallons per day of treated water from the TOM. The purchase of water may allow
the wells that require softening to be taken off line thus eliminating all three discharges. The
interconnection with the TOM will occur later this summer. CWS indicated they may be able to negotiate
additional water purchase from the TOM in the future.

Based on this information, I understand that CWS might be able to comply with the draft permit. The three
year time limit to fully evaluate the TOM interconnect and possibly eliminate the discharges seems
reasonable. Without the TOM interconnect, there doesn't appear to be any other viable alternatives.
If you have any questions, please call me at [phone].

BIMS Downloads and Renewal Review Summary:
• For renewal: Updated effluent page in accordance with Ion Exchange WTP technology guidelines (2009); updated permit
template, facility location, facility description, and added 8 Digit 14UC to the map; Added parameter monitoring and limits
based on zero flow conditions (IWC=100%) using Reasonable Potential Analysis. DMR's from August 2008 —June 2011
reported a maximum flow of 0.058 MGD and an average flow of 0.002 MGD. The maximum, monthly average flow from
01-2010 through 12-2012 was 0.0091 MGD which was used in the RPA analysis per WTP Strategy.
• Flow Monitorinc — Reviewed flow data and in accordance with the WTP Strategy revised the monitoring frequency for flow
to twice monthly, which is as frequent as the minimum frequency of monitoring for any parameter listed. Included a footnote
that the facility is to record and report flow the date of sampling.
• Toxicity- The facility has failed 17 out of 20 toxicity tests in the past 5 years. Permit draft requires the facility to conduct
quarterly toxicity monitoring in conjunction with the sampling of manganese, zinc, iron, copper, and lead.
• Compliance Record — The BIMs records indicate the facility has one penalty assessment LV-2009-0045 for TSS daily
maximum exceeded and one TSS monthly maximum exceeded resulting from DMR data collected in October 2008.
• Effluent data — indicates the current discharge treatment may not be adequate to meet the North Carolina Water Quality
Standards for total dissolved soolids, manganese, chloride, and lead.
• TRC —IWC calculation completed for TRC using S7Q 10 (CFS) =zero and a maximum, monthly average flow of 0.009 MGD
Page I 1

Permit NC0084565
• Reasonable Potential Analysis —Reasonable potential to violate water quality standards were shown for copper, zinc, lead,
iron, chloride, total dissolved solids, and manganese. Since copper, zinc, and iron have action level standards and should be
reviewed in conjunction with toxicity testing it is recommended that monitoring for these parameters remain in the NPDES
permit at a measurement frequency of quarterly. Limitations based on water supply standards and aquatic life water quality
stanadards were added to the permit for lead, chloride, total dissolved solids, and manganese.
• Nutrient Monitoring — The water body is not subject to the NSW classification and since the maximim, monthly average flow
is less than 0.05 MGD (DMR data from August 2008 — June 2011) TN and TP were removed from the permit.

Subject: RE: CWS draft permits
I know, Julie. And Britt knows it as well, I just wanted to tell you what he said. I did think the connection was good news.
Although CWS has not planned on it, they may be able to take off the wells with highest hardness and significantly reduce the
softener use.

Donna,
I believe we are all aware they can not meet these limits using ion exchange as their method of treatment. However, I do not
have the authority to allow them to continue to violate WQS. Therefore, they must assess alternatives to demonstrate to the
state what they can or can not do to comply and we will have to progress from there.

Britt said 'They will never be able to meet these! I will make comments when I crosses my desk.'
He also stated an peak source/emergency connection to the Town of Mooresville was being proposed. That is
the only good news I heard.
If you need anything else, let me know.
Thanks,

Subject: CWS draft permits
Donna,
Just checking in to see if you have had a chance to review the draft permits I have written for the three Carolina
Water Service's Ion Exchange WTPs.
Also, hoping you have shown them to Britt Setzer as we discussed. Mike and I discussed the drafts several
weeks ago but I would like to offer to have a conference call with you, Britt and Mike, if desired, to answer any
questions or concerns before this goes to Public Notice next week.
The bottom line is that NPDES must enforce Water Qulaity water supply standards. I think the permit helps to
clarify specifically what parameters are of concern, and what steps they need to take to asssess alternatives in
order to determine the most feasible and environmentally sound alternative.
Thanks for your help on this matter,
Julie

ARR DRAFT 04-03-2012
Site observations for The Point Well #1 was as follows:
One trane of softners was observed receiving flow from five wells influent flowing through the WTP.
CWS indicated that the units were installed around 1998-2000 and regular maintenance is performed on
the units. The units work as designed to remove hardness, but the resin has never been cleaned or
replaced to date. There were two settling tanks in series (approximately 1,000 gallons each). Backwash
volume at peak load was reportedly 1 backwash daily of approximately 300-400 gallons of discharge per
backwash. Based on this information, it would appear that the settling tank may have some settling
capacity, but that was unclear. The IE units are operated based solely on the volume of water flow from
the well system.
Results and Recommendations:
CWS agreed to sample in April 2012, the Point Well #1 influent and effluent for the constituents' in the
draft permit and offered to contact the IE WTP Softner Technical Service Representative for the purpose
of system optimization.
Historical Sampling and results to consider for sample planning and treatment optimization:
A review of 2010 and 2011 Wells #1, #2, and #4 groundwater data from Public Water Section web site
did not include results for Chloride, TDS, Copper, or Zinc. The data also did not include Nitrate, the
receiving water body is not nutrient sensitive, however, the last permit cycle Total Nitrogen data was
collected and the Total Nitrogen results from the WTP discharge were elevated. Since there is a
groundwater standard for Nitrate, I would recommend sampling the wells for Nitrate. Well
groundwater results were reported for Hardness 19 mg/L and 123 mg/L, respectively, and for
Manganese reported as less than .01 mg/L. The average Manganese results reported from Wells #1,
#2, and #4 WTP discharge were significantly higher, they were .675 mg/L and .265 mg/L, respectively.
Well groundwater results for Iron were also reported as less than 0.01 mg/L for wells #1, #2, and #4.
However, WTP discharge average results reported for Iron were 0.18 mg/L and 0.25 mg/L, respectively,
with maximums reported at 1.3 mg/L and 1.2 mg/L, respectively.
Also, Sodium results were included from Wells #1, #2, and #4 in the 2010 and 2011 groundwater data
published by the Public Water Section. The groundwater sodium results were 8953 ug/L and 13, 900
ug/L, respectively. This is important to note since the IE WTP unit is converting Ca and Mg to Sodium
salts. It is also important to note that higher TDS usually in the form of CaCO3, lowers the exchange
capacity, so hardness and TDS can be monitored for process control and WTP optimization.

Subject: Issuance of NPDES Permit
NCO084565
The Harbour WTP — Wells #1 and #2
Iredell County
Dear Mr. Lashua:
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES permit. This permit is issued pursuant to the
requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North
Carolina and the U.S. Environmental Protection Agency dated May 9,1994 (or as subsequently amended).
In response to your questions/comments on the draft permit:
➢ A summary of our permitting strategy for ion -exchange water treatment plants was included with your
draft permit. In your comments you indicated the "permitting strategy appears flawed." The full
workgroup findings, along with the participants involved on the workgroup, is available on our
website athttp://h2o.enr.state.nc.us/NPDES/documents.html. The 77-page document is entitled
"Assessment and Recommendations for Water Treatment Plant Permitting: Findings of the Water Treatment
Plant Workgroup." The new permitting strategy for water treatment plants affects all membrane and
sodium cycle cationic exchange water treatment plants regardless of the facility's compliance history.
➢ We understand that the new requirements will increase man-hours and costs associated with the
operation of your facility. The new requirements are an attempt by the Division to collect more
information about the nature of your discharge so that we can properly characterize your effluent, as
well as the effect your discharge may have on the receiving water. These requirements are consistent
for all water treatment plants using ion exchange technology. By requiring monthly monitoring for the
new parameters, we aim to minimize the disruption to your operations while still gathering important
data. We don ot believe that these requirements pose an impractical burden on a properly operated
facility. The Divisiortwill ie-evaluate the monitoring requirements at the next permit renewal in 2010.
➢ Please contact Jim Meyer` in'the Lab Certification Branch at [phone], extension 207 with any
questions about the procedure for obtaining specific parameter certifications or for obtaining a list of
certified laboratories.
➢ In your comments you indicated there is no upstream or downstream flow in the receiving water,
except during rain events. The stream monitoring requirement will remain in the permit. However, if
when sampling is conducted there is no stream flow, then simply indicate "No Flow" on the monitoring
report.
➢ With regard to your comment that the conductivity monitoring requirement has been removed from
"Most all NPDES permits," this is not entirely correct. The instrearn monitoring requirement for
conductivity was removed from those NPDES permits with 100% domestic wastewater only. Your
facility, an ion -exchange water treatment plant, does not fall into this category, and hence is still subject
to the instream conductivity monitoring requirement.

➢ As indicated in the transmittal letter with the draft permit, a total residual chlorine (TRC) limit has been
added to the permit. The TRC limit will not take effect until eighteen (18) months after the effective
date of the final permit. This eighteen (18) month grace period, which will conclude on October 31,
2006, will allow you the needed time to make any modifications to your plant as well as time to
purchase new equipment or to find a certified laboratory able to conduct the TRC analysis. The
Division's TRC policy memo was included with your draft permit.
➢ In your comments you objected to the need for the chronic toxicity testing requirement. You stated,
"We oppose my testing requirement for parameters that do not have a proposed limit." Again we
understand the requirements will increase man-hours and costs associated with the operation of your
facility. The new requirements are an attempt by the Division to collect more information about the
nature of your discharge so that we can properly characterize your effluent, as well as the effect your
discharge may have on the receiving stream. At this time, your permit currently includes chronic
toxicity monitoring. This is not a "pass/fail' test; rather the purpose is to gather information about the
nature of your discharge. We need to determine whether your effluent discharge has a toxic effect on
the receiving stream. Based on the data gathered, we will be able to determine whether or not future
limits will be required. At this time we do not have sufficient information to make this determination.
The Division may re-evaluate this monitoring requirement at the next permit renewal in 2010.
This permit includes a TRC limit that will take effect on November 1, 2006.
If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable to
you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following
receipt of this letter. This request must be in the form of a written petition, conforming to Chapter 150B of the
North Carolina General Statutes, and filed with the Office of Administrative Hearings (6714 Mail Service
Center, Raleigh, North Carolina 27699-6714). Unless such demand is made, this decision shall be final and
binding.
Please note that this permit is not transferable except after notice to the Division. The Division may require
modification or revocation and reissuance of the permit.
This permit does not affect the legal requirements to obtain other permits which may be required by the
Division of Water Quality or permits required by the Division of Land Resources, the Coastal Area
Management Act or any other Federal or Local governmental permit that may be required. If you have any
questions concerning this permit, please contact Vanessa Manuel at [phone], extension 532.

with residential housing. There is no dwelling planned within 100 feet of the current site.
10. Receiving stream or affected surface waters: U.T. to Lake Norman (Catawba River)
a. Classification: WS-IV, B, CA
b. River basin and subbasin no.: Catawba 030832
C. Describe receiving stream features and pertinent downstream uses: The discharge
enters a dry stormwater ditch and travels = 300 feet before entering a cove of
Lake Norman.
PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
a. Volume of wastewater: Intermittent (backwash water from ion -exchange filters)
b. What is the current permitted capacity: N/A
C. Actual treatment capacity of current facility (current design capacity): N/A
d. Date(s) and construction activities allowed by previous ATCs issued in the
previous two years: N/A
e. Description of existing or substantially constructed WWT facilities: The existing
filters use a cation exchange resin for hardness (CaCO3) removal. A concrete
settling tank is the only form of wastewater treatment.
f. Description of proposed WWT facilities: There are no proposed WWT facilities.
g. Possible toxic impacts to surface waters: There are no toxic impacts expected.
h. Pretreatment Program (POTWs only): Not Needed.
2. Residual handling and utilization/disposal scheme: Residuals generation is not expected
and has not occurred since the WTP system has been installed.
3. Treatment plant classification: Based on the current classification guidelines, this facility

facility.
2. Special monitoring or limitations (including toxicity) requests: None at this time.

Page Three
4. Alternative analysis evaluation
a. Spray Irrigation: Insufficient area, Catawba River buffer concerns.
b. Connect to regional sewer system: none presently available to the site.
C. Subsurface: Limited area is available on the current site. It should be noted that
there is essentially no organic material in the wastewater that would be necessary
to establish anaerobic decomposition in a septic tank. Therefore, subsurface
disposal is not being considered as an option at this time.
d. Other disposal options: N/A
PART IV - EVALUATION AND RECOMMENDATIONS
The applicant requests renewal of the NPDES permit that authorizes a discharge of filter
backwash from a community drinking water well with cation exchange resin water softeners. The
filters backwash intermittently and discharge into a settling tank that eventually discharges into a
stormwater channel that drains to Lake Norman. The filters are designed to remove CaCO3
(hardness) from the well water.
Pending a final review by the NPDES Permitting Unit, it is recommended that the Permit
be renewed as request

Subject: Modification of NPDES Permit NCO084565
The Harbour WTP
Iredell County
The Division issued the subject permit on May 29, 2000. The permit contained upstream & downstream
monitoring for turbidity. Recently, personnel from the NC DENR Mooresville Regional Office forwarded your
request to change this monitoring from instream to the effluent.
This modification removes the instream monitoring for turbidity and replaces it with a daily maximum turbidity
limit [25 NTU]. No other changes to the permit have been made.
Please find enclosed the revised effluent limitations page, which should be inserted into your permit. The old
page may then be discarded. All other terms and conditions contained in the original permit remain unchanged and
in full effect. This permit modification is issued under the requirements of North Carolina General Statutes 143-
215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency.
If any parts, measurement frequencies or sampling requirements contained in this permit modification are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days
following receipt of this letter. This request must be a written petition conforming to Chapter 150B of the North
Carolina General Statutes, filed with the Office of Administrative Hearings (6714 Mail Service Center, Raleigh, North
Carolina 27699-6714). Unless such demand is made, this decision shall be final and binding.
If you have any questions concerning this permit modification, please contact Charles Weaver of the NPDES
Unit at [phone], extension 511.

a. Classification: WS-IV, B CA
b. River Basin and Subbasin No.: Catawba 030832
C. Describe receiving stream features and pertinent downstream uses: The discharge
enters a dry stormwater ditch and travels = 300 feet before entering a cove of
Lake Norman.
PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
a. Volume of Wastewater: Intermittent (backwash water from ion -exchange filters)
b. What is the current permitted capacity: N/A
C. Actual treatment capacity of current facility (current design capacity): N/A
d. Date(s) and construction activities allowed by previous ATCs issued in the
previous two years: N/A
e. Description of existing or substantially constructed WWT facilities: The existing
filters use a cation exchange resin for hardness (CaCO3) removal. A concrete
settling tank is the only form of wastewater treatment.
f. Description of proposed WWT facilities: There are no proposed WWT facilities.
g. Possible toxic impacts to surface waters: There are no toxic impacts expected.
h. Pretreatment Program (POTWs only): Not Needed.
2. Residual handling and utilization/disposal scheme: Residuals generation is not expected
and has not occurred since the WTP system has been installed.

4. Alternative Analysis Evaluation
a. Spray Irrigation: Insufficient area, buffer concerns.
b. Connect to regional sewer system: none available.
C. Subsurface: Limited area is available, however, there is essentially no organic
material in the wastewater that would be necessary to establish anaerobic
decomposition in a septic tank. Therefore, subsurface disposal is not being
considered as an option at this time.
d. Other disposal options: N/A
PART IV - EVALUATION AND RECOMMENDATIONS
The applicant requests renewal of the NPDES permit that authorizes a discharge of filter
backwash from a community drinking water well with cation exchange resin water softeners. The
filters backwash intermittently and discharge into a settling tank that eventually discharges into a
stormwater channel that drains to Lake Norman. The filters are designed to remove CaCO3
(hardness) from the well water.
Pending a final review by the NPDES Permitting Unit, it is recommended that the Permit
be renewed as requested.

Authorization is hereby granted for the construction of a well water softener backwash treatment system
with discharge of treated wastewater into the Catawba River. Other appurtenances such as water mains are
not authorized herein and may require additional permit submittals.
r
This Authorization to Construct is issued in accordance with Part III, Paragraph A of NPDES
Permit No. NCO084565 issued May 30, 1995 and shall be subject to revocation unless the wastewater
treatment facilities are constructed in accordance with the conditions and limitations specified in Permit No.
NC0084565.
In the event that the facilities fail to perform satisfactorily, including the creation of nuisance
conditions, the Permittee shall take immediate corrective action, including those as may be required by this
Division, such as the construction of additional or replacement wastewater treatment or disposal facilities.
The Mooresville Regional Office, telephone number [phone] shall be notified at least forty-
eight (48) hours in advance of operation of the installed facilities so that an in -place inspection can be
made. Such notification to the regional supervisor shall be made during the normal offil-e hours from 8:00
a.m. until 5:00 p.m. on Monday through Friday, excluding State Holidays.
Upon completion of construction and prior to operation of this permitted facility, a certification
must be received from a professional engineer certifying that the permitted facility has been installed in
accordance with the NPDES Permit, this Authorization to Construct and the approved plans and
specifications. Mail the Certification to the Permits and Engineering Unit, P.O. Box 29535, Raleigh, NC
27626-0535.
Upon classification of the facility by the Certification Commission, the Permittee shall employ a
certified wastewater treatment plant operator to be in responsible charge (ORC) of the wastewater treatment
facilities. The operator must hold a certificate of the type and grade at least equivalent to or greater than the
classification assigned to the wastewater treatment facilities by the Certification Commission. The
Permittee must also employ a certified back-up operator of the appropriate type and grade to comply with
the conditions of Title 15A, Chapter 8A, .0202. The ORC of the facility must visit each Class I facility at
least weekly and each Class II, III, and IV facility at least daily, excluding weekends and holidays, and

all other conditions of Title 15A, Chapter 8A, .0202. Once the facility is classified, the Permittee must
submit a letter to the Certification Commission which designates the operator in responsible charge within
thirty days after the wastewater treatment facilities are 50% complete.
A copy of the approved plans and specifications shall be maintained on file by the Permittee for the
life of the facility.
Failure to abide by the requirements contained in this Authorization to Construct may subject the
Permittee to an enforcement action by the Division of Environmental Management in accordance with
North Carolina General Statute 143-215.6A to 143-215.6C.
The issuance of this Authorization to Construct does not preclude the Permittee from complying
