FACILITY OVERVIEW:
This facility is a public nonprofit water treatment plant that is 100% industrial waste and treats well water to
produce finished potable water for portions of Carteret County. The facility has a designed potable water flow
of 2.0 MGD and generates filter backwash and rinse water flows with a maximum monthly average wastewater
discharge of 0.136 MGD. The system utilizes:
• four (4) greensand filters (iron removal) [flow capacity 400-gpm each] with shared flow -
meter system [optional feed potassium permanganate (KMn04) - disinfection]
• eight (8) water -softeners with brine regeneration and two (2) flow-meters(four
softeners going to each flow meter) [flow capacity 240 gpm each]
• six (6) ionic color filters with brine regeneration and shared flow -meter [flow
capacity 320 gpm each]
• settling lagoon [70 ft. x 36 ft.] for ionic color filters; with pump station
• settling lagoon [52 ft. x 52 ft.] for water -softeners w/ pump station (active, but
currently bypassed to lift station)

• twelve (12) drying beds [each 50 ft. x 20 ft.] receiving green -sand filter backwash
• appurtenant piping, pumps, and system operational controls
chemical additives (all part of water treatment process):
- ammonium hydroxide (NH4 OH) [disinfection]
- chlorine gas (C12) [disinfection]
- ortho-polyphosphate (04P 3) [scale inhibitor]
Raw Water Treatment Process: (from application, historical documents and emailed add -info)
Well water from seven (7) active wells (one well currently inactive - #4) goes through an aerator and into
ground storage tanks. From storage tanks water enters the water treatment process - first being sent through
greensand filters which can, as needed, be activated with potassium permanganate (not currently happening
due to low iron levels in the raw water). The water then passes though ion exchange filters for softening and
then additional ion exchange filters for color removal. The water is then treated with ortho-polyphosphate
(scale inhibitor) , chlorine gas and ammonia before going to the distribution system or storage.
Wastewater and Treatment Process: (from application, historical documents and emailed add -info)
Wastewater generated from the system comes from backwash water, rinse water and regeneration water. The
three systems - greensand (iron filter), softener and color - are each maintained independently, have separate
effluent wells and flow meters and can be monitored separately before they all combine in an outfall pipe that
has a flow meter and can be monitored as final discharge. The iron filters are backwashed using potable water
and rinsed using raw water. Iron filter effluent is discharged to the series of drying beds where solids are
removed and liquid flows to the effluent well and then to the discharge. The softener and color ion exchange
units use raw water for backwash and rinse water and potable water for the brine solution for regeneration.
Softener and color systems are each set up to send their effluent through a sand filter lagoon. At the current
time only the color system is utilizing its sand filter lagoon.
APPLICATION
The application does not indicate any changes in the facility or treatment since the last renewal of the permit.
The treatment system is operated by West Carteret Water Corporation. The application does not indicate
potable design flow rate. The backwash reject average flow is given as 0.058MGD for softeners, 0.019MGD for
greensand iron and 0.022MGD for color removal. There is no timeframe indicated for discharge, but the
application does indicate that flows are not intermittent, so discharge is regular. For Table A Parameters the
applicant requested waiver of monitoring for BOD, COD, TOC, and Temperature. Most of these parameters do
not appear to be of major concern for this facility and the Division approves the requested waiver. Table B
parameters are largely indicated as believed to be absent with the exception of copper, lead and zinc. Table C
parameters are also mostly believed to be absent except for chlorine and manganese. The application indicates
that the softener sand filter lagoon is only used as overflow. Environment 1 is noted as a contractor that helps
with monitoring issues for the facility.
INSPECTION
The most recent inspection occurred on March 18, 2022. The inspection report gave a detailed description of
the water and wastewater components and noted the system as located at 4102 NC Highway 24. The report
indicated that the system has increased from six (6) to nine (9) wells, with eight (8) being used and had an
increase in backwash flow to an average in 2021 of 0.106MGD. The inspection report also noted the addition of
one softener filter - now eight (8) total and one color filter - now six (6) total. These additions were not
reported in the application. The permittee was asked to verify these additional components and did verify the
addition of a softener and color filter. The permittee indicated that there were seven wells currently in use and one
inactive (well #4).
The inspection report noted the system has four (4) flow meters, one (1) each on the iron and color flows and
two (2) on softener and that these are summed for the system flow. The inspection outlined that finished water
West Carteret WTP Fact Sheet
NPDES Renewal 2023 — October 18, 2023; updated October 30
Page 2

was used for iron backwash and for brine for regeneration. The facility was indicated as being well run and
maintained and the only need reported was for calibration of flow meters. The inspection report indicates that
the facility is utilizing past instructions/guidance from the Regional Office for preparing manual composite
samples from each of the waste streams
The inspection report noted that the location for the outfall in the permit and in BIMS were incorrect. Regional
office staff provided information for more accurate location of the outfall point and changes were made in BIMS
and on the permit map.

The data reviewed for the renewal is from November 1, 2017 through August 2023.
REVIEW OF PERMIT LIMITS:
Flow - The facility's average flow from DMR records is 0.0995MGD. Duration of flow was previously required
to be maintained in permittee logs. This parameter can now be reported in eDMR. The permit Effluent Table
has been changed to include Duration of Flow.
TSS - No limit violations occurred over the permit cycle.
TRC- There were four (4) exceedances of the 13 µg/L limit, but no values were above the compliance level of
50µg/L.
Turbidity - Highest value of 7.2 NTU so no issues shown with this parameter.
Total Manganese - There is no NC standard due to the high natural occurrence of manganese in surface waters
in NC. This parameter was not included in the 2017 permit though it had been in previous permits. There was
no discussion in the Fact Sheet about its removal. The permittee continued to monitor and report on this
West Carteret WTP Fact Sheet
NPDES Renewal 2023 - October 18, 2023; updated October 30
Page 3

parameter. The WTP guidance suggests monitoring for manganese rather than limits. Given the greensand
system, etc. the monitoring parameter will be added back into the permit as a monitoring and report parameter.
Lead - This parameter was actually removed from the permit in the last renewal, but the permittee continued to
monitor. The permittee will be advised again that this parameter has been removed from the permit.
Total Dissolved Solids, Conductivity and Salinity - Values for these parameters tend to be high for outfall and
downstream, but the nature of the facility probably plays into these numbers.
RPA Analysis (Copper, Lead and Zinc)- Reviewed the last three years of data as specified in the WTP Guidance.
Copper - All values reported as less than 10 µg/L in the last 3 years of data. These values, even at 1/2 the less
than value, are above the allowable and show reasonable potential. Monitoring for total copper will be
increased to monthly and limits will be set at: monthly average - 1.85 µg/L and daily max of 2.9 µg/L. The
permit includes a compliance schedule that will make the permit limits effective with the next permit issuance.
The cover letter for the draft permit will note the need for parameters data to be analyzed to the appropriate
PQL level. Copper should be reported to 2 µg/L.
Lead - This parameter was actually removed from the permit in the last renewal, but the permittee continued to
monitor. Similar to the last permit cycle, lead has only produced non -detection levels so no further monitoring
is required. This will be pointed out again in the cover letter for the draft permit.
Zinc - Zinc reasonable potential results did show 4 of the 15 values above detection as being above the
allowable level, so reasonable potential does exist. Monitoring for Total Zinc will be increased to monthly and
limits will be set at: monthly average - 42.8 µg/L and daily max of 47.6 µg/L. The permit includes a compliance
schedule that will make the permit limits effective with the next permit issuance.
Discussion of the outfall location with regional office staff also brought up an issue of whether the downstream
location was appropriate and producing reasonable data results. It is probably best for the regional staff to
work with the facility at the next inspection to look at the instream monitoring locations.
COMPLIANCE:
During the permit cycle this facility had no violations or enforcement actions.

• July 31, 2002 - Permit Renewal - Only change appears to be the addition of a footnote to highlight the
turbidity standard of 25 NTU. Permit notes color removal and softener backwash as parts of water
treatment process.
• March 24, 2005 - Permit Modification allowing the permittee to take softener wastewater flow and bypass
the sand filter system directly to the effluent well. Wastewater from the color system was to still go through
its sand filter system prior to the effluent well. Two years of data was reviewed in making the modification.
• September 1, 2006 - Permit Modification to allow for the addition of iron removal process to the water
treatment system with approval of an Authorization to Construct. The permit also included a number of
new parameters:

The permit set an 18 month compliance window for composite monitoring added for some parameters. Did
not find a signed version of this permit, only word documents on the shared drive. BIMS does show as
issued as a modification and with the parameters noted.
August 1, 2007 - Permit Renewal - This renewal added TRC monitoring with a 13µg/L limit with an 18
month compliance period. The permit included the TRC compliance level of 50 µg/L. This permit noted
color and softener backwash in the permit but did not include info on iron removal or language about an
ATC for addition of this treatment component.
July 1, 2010 - Files on the shared drive include a 2010 permit correction to update WET requirements, but
this correction is not shown as an issued permit in BIMS so possibly it was never finalized.
September 11, 2013 - Permit Renewal - This renewal added instream monitoring parameters, added
Turbidity monitoring to meet EPA requirements, removed DO, Total Fe, TN, TP and Temperature effluent
monitoring and reduced some monitoring frequencies.

Some language was added related to proper monitoring of certain parameters during specific discharge
events. Language was also added to the supplement page to describe the system and its water and
wastewater treatment components more completely. This included the addition of greensand wastewater
flows. This renewal had original requirements for automatic composite sampling but the Division's
Wilmington Regional Office staff worked with the permittee to establish a composite approach using grab
samples.
September 19, 2017 - Permit Renewal - This renewal removed the requirement for Total Lead (Pb)
monitoring due to 110 samples at "not detected" level. Total Manganese was also missing in the permit but
there was no discussion of why it was removed. The permittee has continued to monitor and report for
both parameters. General changes to language included in the permit and a section describing composite
Sampling Requirements was included. This language was taken from sampling protocol established by the
Wilmington Regional Office in an inspection on May 12, 2017.
PROPOSED PERMIT CHANGES:
• Updated eDMR requirements to be consistent with final EPA rule.
• Added regulatory citations throughout permit as needed.
• Based on RPA analysis limits added for Total Copper and Total Zinc. The draft includes a compliance
schedule for the limits to become effective in the next permit renewal.
• Duration of Flow added to Effluent Table - eDMR code 81381.
• Total Manganese monitoring added back to permit monitoring.
• Permit map information updated including outfall location update.

Bradley,
Thank you for the permit draft. I'm traveling and Bryan called me last night to discuss it after he and our Lab Manager
reviewed yesterday. At that point, I had only read about half the permit.
Bryan had several questions and we are going to circle back together with our engineer to ensure we are reading it
correctly, particularly regarding testing. At that point, I may need to speak with you directly.

Subject: RE: Draft WTP for Review - West Carteret WTP - NCO077143
Hey Bradley,
Here are my comments on the draft permit for West Carteret WTP! Let me know if you'd ever prefer these in a separate
Word doc, or if email is still fine.
Permit:
• I saw the email conversation about the conflicting addresses provided. Did the permittee ever respond?
• Cover letter has different fonts for some of the different points.
• Supplement to Cover Sheet only references the avg discharge flow, not the maximum monthly avg.
• Effluent table is missing the new limits for Copper and Zinc, even though they won't become active yet.
• TRC limit should only be under the Daily Max column.
• eDMR code for TSS should be'C0530'
• Compliance Schedule condition has different language than I've seen before. I think it should be updated,
especially because it references the Raleigh Regional Office instead of Wilmington.
• Footnote for eDMR references condition A (4) instead of A (5)
• Footnote for Compliance Schedule references condition A (5) instead of A (4)
Fact Sheet:
• Top of fact sheet says '2021 renewal'
• Under the review of permit limits section, for TRC it states the limit is 17 instead of 13.
Under the RPA analysis section, for Copper it states that all values reported were less than 10. When I looked at
the data for the RPA, I didn't see any'<' symbols with the values. The RPA might need to be re -run with all of the
< symbols added.

additional pieces of information that I would like to ask for and these areas are outlined below. You can respond to me
on these through email.
Verification of Address Information:
Information in our files and your application includes two different addresses — 4102 and 4104 Highway 24. We have
generally used 4102 as the mailing address and the permit notes the facility location as 4104. Your recent application
showed 4104 for both and I just wanted to verify. 4102 — Administrative Office and Mailing for both the office and water
plant; 4104— Water plant physical location, but not used for mailing purposes.
Treatment Components:

Could you please review and verify the following treatment components for your system. .
• four (4) greensand filters (iron removal) [flow capacity 400-gpm each] with shared flow -
meter system [optional feed potassium permanganate (KMnO4) - disinfection] Correct
• seven (7) water -softeners with brine regeneration and shared flow -meter [flow
capacity 240 gpm each] 8 Water Softeners; 4 on one flow meter and 4 more on
another
• five (5) each ionic color filters with brine regeneration and shared flow -meter [flow
capacity 320 gpm each] 6 Color Vessels; 1 flow meter
• settling lagoon [70 ft. x 36 ft.] for ionic color filters; with pump station Correct
• settling lagoon [52 ft. x 52 ft.] for water -softeners w/ pump station (not currently
active) Active, by bypassed directly to lift station as approved by DWR
• twelve (12) drying beds [each 50 ft. x 20 ft.] receiving green -sand filter backwash
Correct
Also, can you provide information on the number of ground water wells utilized for your and verify the capacity of your
potable water system (our records indicate 2 MGD). 7 active; 1 inactive (Well No. 4)
Electronic Submittal Of Permit Documents:
In order to provide more convenience, control, and security to our permittees and assist them in processing their
transactions, The Division of Water Resources is currently transitioning towards electronic correspondence. This will
hopefully provide more efficient service to our permittees and other partners and will allow us to more effectively
process and track documents. We are writing to ask you for your approval of the transmittal of documents related to
your permitting and related activities with the Division in an electronic format. Documents will be emailed to the
appropriate contact person(s) in your organization in a PDF format. Yes, we do approve electronic format for permitting

Thanks Tom. The sampling protocol was actually added to the last permit so there is some language already there. I just
wanted to make sure I understood what it was doing and that it was accomplishing what the region needed. Here is the
language from the 2017 permit. I think this comes from the May 12, 2017 inspection report. The way it reads it sounds
like the do 2 separate composite samples each month with the WET test alternately conducted on each of these. Are
the two composites then combined to get the sample for the analysis of other parameters? We can set up a Teams call
to discuss if that would be easier.
A. (3.) COMPOSITE SAMPLING REQUIREMENTS
[G.S. 143-215.661
Considering the complexities of the existing treatment systems and their operation, the Permittee shall implement
two (2) separate composite sampling protocols (see 1 and 2 below). The Permittee shall compile 24-hour
composites by combining flow -proportional grab -samples specific to given discharge events. To ensure that each
composite sample accurately represent a 24-hour discharge period, the Permittee may collect more than one grab
sample of each event.
The Permittee shall compile two (2) different composite samples per month, in accord with the following
instructions:
1. One 24-hour composite shall combine each of:
a. color -filter discharge (flow -proportional grabs), and
b. softener discharge (flow -proportional grabs).
2. Another 24-hour composite shall combine flow -proportional grabs of each softener -
regeneration step.
3. WET -test analyses shall alternate between the color -filter composite samples and
the softener composite samples.
Records and descriptions of all manual composites shall be kept on file and onsite, available for review by the
Wilmington Regional Office.

Hey Bradley, I have copied Bryan Lievre and Steve West into this email chain. Helen and I talked about this and from
what we understand this was a sampling protocol established to obtain the most representative sample that we could
get given the process ( I believe Steve West worked with them on this). Maybe Bryan or Steve could add some additional
info on the subject as they both spent time in Public Water. From Helen's description it seems adding the sampling
protocol into the permit might be difficult and it might be best to include a statement referring them to "regional office
guidance regarding effluent sampling". If that's something you can do on a permit like this.

requirements in the permit. It looks like they are compositing requirements that the region may have worked out with
them in the past. I was wondering if any of you guys remembered this and would have time to discuss with me?
Thanks

Hey Guys,
Just wanted to let you know that I will be working on the renewal applications listed below over the next few
weeks. The applications for each of these is available in Laserfiche. If you have any concerns about these or any
information you think we should consider in the renewal, please let me know. As soon as I have drafts available, I'll send
them to you for review.

Saltwater streams are tidal resulting in a1111MC % = 100%.
If an approved model is conducted then a chronic dilution
factor is determined and can be applied to a discharge to
calculate its IWC %. If a stream is classified as a SA or
ORW then its is also classified as a HQW. The appropriate
IWC % must be defined to properly calculate WQS-based
limits.
