Subject: Issuance of NPDES Permit
NCO086606
The Harbour—Wells#4 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 elated 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 2B .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 gg/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

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.

A. (2.) CHRONIC TOXICITY PASS/FAIT.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 i
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.

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:
htt-p://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 low flow conditions(IWC=100%)using Reasonable Potential Analysis.The maximum flow reported between
Jan.2008 and Dec.2012 was 0.053 MGD and the daily average flow was 0.0078 MGD.The maximum,monthly average
flow from 01-2010 through 12-2012 was 0.019 MGD which was used in the RPA analysis per the WTP Strategy.
• Flow Monitorins—Reviewed flow data and in accordance with the WTP Strategy revised the monitoring frequency to twice
monthly,which is as frequent as the minimum frequency of monitoring required by other parameters listed in the permit.
Included a footnote that the facility is to record and report flow the date of sampling.
• Toxici -The facility has failed 19 out of 20 WET tests in the past five 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 no penalty assessments resulting from DMR data. The
facility has one Notice of Violation(NOV)for Permit Condition Violations noted during the July 2009 Compliance
Inspection. [Bims query from 5/2008—8/2011 is null for limit violations]see attached EPA Inspection Form and Permit
Condition Violation NOV-2009-PC-0724.

Standards for total dissolved solids,manganese,chloride,and lead.
• .TRC—IWC calculation completed for TRC using S7Q10(CFS)=zero and maximum,monthly average flow of 0.019 MGD
• 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

• 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(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 50µg/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.

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.

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.

Re: The Harbor and The Point NPDES Permits
NCO086606,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 significant 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.

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/l
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/l—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/l—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.

Julie Grzyb

Page 3 of 3
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(704)663-1699.

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 low flow conditions(IWC=100%)using Reasonable Potential Analysis.The maximum flow reported between
Jan.2008 and Dec.2012 was 0.053 MGD and the daily average flow was 0.0078 MGD.The maximum,monthly average
flow from 01-2010 through 12-2012 was 0.019 MGD which was used in the RPA analysis per the WTP Strategy.
• Flow Monitoring—Reviewed flow data and in accordance with the WTP Strategy revised the monitoring frequency to twice
monthly,which is as frequent as the minimum frequency of monitoring required by other parameters listed in the permit.
Included a footnote that the facility is to record and report flow the date of sampling.
• Toxici -The facility has failed 19 out of 20 WET tests in the past five 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 no penalty assessments resulting from DMR data. The
facility has one Notice of Violation(NOV)for Permit Condition Violations noted during the July 2009 Compliance
Inspection. [Bims query from 5/2008—8/2011 is null for limit violations]see attached EPA Inspection Form and Permit
Condition Violation NOV-2009-PC-0724.
• 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.
1 Page

Permit NCO086606
• TRC—IWC calculation completed for TRC using S7Q10(CFS)=zero and maximum,monthly average flow of 0.019 MGD
• 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 maximum,monthly average
flow is less than 0.05 MGD(DMR data from Jan.2010—Dec.2012)TN and TP were removed from the permit.

ARR DRAFT 04-03-2012
Carolina Water Service(CWS)-Ion Exchanite Water Treatment Plants(IE WTP's)
March 30, 2012 Meeting @ Mooresville Regional Office
*0ject:PerMi R�,e al oe t ,lour VI a 4� r,1A #1 a ct, , 2,1 i
Site observations for Harbour Well#4 WTP was as follows:
Two tranes of softners were observed with each trane receiving flow from six wells for a total of twelve
influent wells flowing through the WTP. CWS indicated that the units were installed around 2001 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 3-4 backwashes per
day of approximately 700-900 gallons of discharge per backwash. Based on this information, it would
appear that the settling tanks do not have the optimum capacity for settling. 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 Harbour Well#4 WTP 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. We discussed 1)sampling the effluent at the settling basin and 2)
sampling the effluent at the end of the discharge pipe. This will enable CWS to determine if the current
sampling location provides a representative sample and to see if results differ between the two
sampling locations.
Site observations for Harbour Well#1 and#2 WTP were as follows:
One trane of softners was observed receiving flow from two wells influent flowing through the WTP.
CWS indicated that the units were installed around 1995, prior to CWS, 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 was one settling tank that appeared to hold (approximately 2,000
gallons). Backwash volume at peak load was reportedly 1 backwash every other day of approximately
900-1000 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 Harbour Well#1 and#2 WTP 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.

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: RE: EPA Audit at MRO? Question on Iredell County WTP's---- I DO NEED YOUR HELP.......
Hi Donna,
After speaking with Julie G. (in WTP permitting),we have a few questions on the DMR data from NCO086606 Harbour
well#4 for the permit renewal.
Can you contact the operator?Allen Glenn Stovall (704-525-7990) and review the following:
DMR's and Prism Lab bench sheets for the following parameters on the following dates:

This data is SUSPECT, because the results reported are extreme outliers in some cases.
If it is CORRECT,then limits would be forthcoming in the new permit. I would rather get the data straight and ensure
what was reported on the DMR was the actual results from Prism Lab with no decimal errors or other errors. If N,
confirmed incorrect, then the ORC will need to do Amended DMRs as soon as possible to avoid the incorrect result
from being used for the renewal of the permit.

Also,they should know that if the lab reports a result using a high PQL,a less than number,then %:of that less than
number can be used to determine if they receive a limit.
For example-4111119" less than 5 me/L was reported on 2/26/2010.That means 2A3"Vgl in my
calculations and that one result could mean the facility will get a limit in the next permit. The lab should be able to
detect down to 25 ug/L,the aquatic water quality narrative standard.
*Prism lab,may report they had to dilute samples and that chloride interference is a problem: looking at the data
below,this could be the case with some results. May be a good idea to check that this data is correct as well.

If confirm ALL DMR results are CORRECT, then the permit will likely have limits in the new permit. We
can discuss, because this will likely cause the permittee to be over limit frequently-meaning SOC, so do
not want to issue permit until these things can be confirmed and discussed with MRO.
I will also be looking at the data from the other Harbour wells 1 and 2, and The Point. May have similar
issues?
Thank you for your time and consideration.

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/l
2. Total Chloride-250 mg/l
3. Total Manganese—200 ug/l
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/l—Total Chloride,6700 ug/I—Total Manganese,28

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.
