FACILITY OVERVIEW:
This facility is 100% domestic waste and treats flow from a town with a population of 1,194 people. The facility
has a permitted flow of 0.275 MGD and as built flow rate of 0.275 MGD. The treatment system includes the
following wastewater treatment components:
• manual bar screen
• grit chamber/grit separator
• influent pump station
• continuous flow meter
• flow splitter box
• dual oxidation ditches with dual brush -type
aeration rotors
• dual in -ditch boat type primary clarifier sections
with sludge wasting pumps
• two circular final clarifiers with RAS/WAS pump
station
• scum pump station
• soda ash feed system
• dual channel UV disinfection unit with mechanical
aeration chamber
• backup chlorination and dechlorination disinfection
equipment
• cascade post aeration
• aerobic digester/sludge holding tank
• sludge drying beds
• standby power generator
• effluent pump station

The Town also holds Collection System permit WQCS00237.
APPLICATION
The application (November 2022) does not indicate any changes in the facility or treatment since the last
renewal of the permit in 2018. The treatment system is owned and operated by the Town of Princeton. The
annual average daily flow is indicated as 0.23 MGD over the last two years falling to 0.15 at the time of the
renewal application. The facility is currently operating within its permitted capacity. Some maximum daily
flows are noted as well above the 0.275 MGD permitted flow.
The application notes the facility minimizes I/I issues through annual smoke tests and repairs as needed. The
application notes the system as having primary and secondary treatment that achieves 90% BOD and TSS
removal. The application describes the system as having an influent pump station where flow is split across the
two oxidation ditches, flows to separate clarifiers and is then combined and sent to UV disinfection before going
to the effluent pump station.
The Town has not yet made an application for an expansion but did recently request Speculative Limits review
for possible expansion. The Division provided a Speculative Limits Letter on January 31, 2023 in response to
this request. The request was for flows of 0.6 MGD and 0.95 MGD. This request included updated USGS flow
numbers of: 7Q10(s) - 1.1 cfs; 7Q10(w) - 13.2 cfs; 30Q2 - 23.3 cfs and Average Flow of 280 cfs. These flows
will be updated in BIMS. The speculative limits were as follows:

The letter notes the need for an Engineering Alternatives Analysis (EAA) and any potential SEPA review
documents prior to any Division final approval of a proposed expansion or the proposed limits were finalized.
The Division requested information from the Town (June 26, 2023 email) concerning the status of any
expansion request. The Town's engineer responded (June 28, 2023 email) with potential timelines. Because it
appeared that there were still a number of unknowns (funding sources, EAA information and review, etc.) the
Division informed the Town that the renewal would proceed based on the November 2022 application at 0.275
MGD flow. Any potential expansion will have to submit appropriate application information including EAA
documentation, etc. In the Review of Permit Limits section below there is additional discussion of issues related to
nutrients and treatment system classification that will also be issues for consideration with expansion.
INSPECTION
The most recent inspections occurred on May 20, 2021. The oxidation ditches were noted as operating
satisfactorily. Noticeable grit was floating on each ditch. Sludge in the 11-foot clarifiers was 1 to 1.5 foot deep.
One aerobic sludge digester was half full. All required monitoring was being performed and consistent with
reported results. The inspection did not note any issues of concern with the facility.
The Town's Collection System (WQCS00237) was last inspected June 15, 2022 and was found to be in
compliance. There was one SSO of 700 gallons in 2020. This occurred during a large rainfall event.

The data reviewed for the renewal is from November 2018 through May 2023.
REVIEW OF PERMIT LIMITS:
Flow - Over the permit cycle the facility has shown average flow of 0.22 MGD. However, the flow since the
beginning of 2022 has averaged 0.17 MGD. So, the flow values have shown some improvement. There were
eight monthly average exceedances over the permit term. The Division sent a Sewer Moratorium letter in May
of 2021 based on the flow in 2020 being at 90%.
BOD / TSS- There were no violations or major issues with BOD and TSS limits. The facility has had no BOD limit
violations over the permit term and has shown average monthly BOD removal of 99%. For TSS the facility did
have two (2) limits violations, but showed average monthly TSS removal of 98%.
Fecal - Data results for Fecal Coliform showed two (2) weekly average limit exceedances for Fecal. No major
ongoing issues indicated
Dissolved Oxygen - The Little River continues to show issues with oxygen demand. There were twenty-one
(2 1) upstream and sixty-eight (68) downstream DO values less than 5 mg/L over the permit cycle. Impacts
from the discharge on this condition need to continue to be evaluated.
Ammonia (NH3-N) - The facility has shown no violations for ammonia limits. Currently the permit has limits in
place only during the summer months. The recent Speculative Limit request resulted in new USGS flow
numbers being developed for the current discharge location. These flow numbers were lower than those used
for previous evaluations for discharge to the Little River. The Division's spreadsheet WLA evaluation forNH3-N
Fecal and TRC resulted in updates to the NH3-N values. This evaluation will reduce the summer monthly
average NH3-N limit to 3 mg/L and result in a summer weekly average limit of 9 mg/L (three times the MA).
The NH3-N number for winter in the WLA evaluation did not require implementation of a limit.
Town of Princeton WWTP Fact Sheet
NPDES Renewal 2023 - July 18, 2023
Page 3

Based on the eDMR data from the previous permit cycle it is possible that these limit changes could have
resulted in a few additional limit violations for the permittee. Consideration will have to be given to any needed
operational adjustments to assure ongoing compliance with the new limits. The draft permit proposes to allow
an eighteen (18) month compliance period for this change with the new limits being effective 18 months from
the effective date of the issued permit. The previous summer limits (12 and 36mg/L) will remain in place for
the first 18 months of the permit. NOTE. In evaluation of the historical permit information below it is noted that
the summer WA limit of 36mg/L seems to have been inappropriately applied in past permits. While this is three
times the MA limit of 1Z Division guidance is to apply a maximum limit of 35mg/L. Since this limit is being lowered
and previous limits are being maintained only for eighteen months, it does not seem reasonable to adjust the limit
to the appropriate 35mg/L.
Whole Effluent Toxicity (WET) - After review of the historical permit documents it appears that toxicity testing
was applied to this facility after a random toxicity test in 1988 failed. This failure was noted as most likely due
to chlorine levels from the discharge, and toxicity requirements were added to the permit. Review of BIMS DMR
data dating back to 2000 does not show any toxicity failures. The Division generally does not require WET
requirements for 100% domestic discharges unless there are issues that indicate potential water quality
concerns. The Princeton facility has shown WET compliance for a considerable amount of time and has updated
their disinfection procedures to utilize UV. Given this review staff feel that removal of the WET requirements is
appropriate and will not impact assessment of compliance for this facility. The draft permit has removed the
WET requirements.
Nutrients
Total Nitrogen load numbers over the permit cycle included a maximum annual load of 7,902 lbs and average
annual load of 7,409. The allocation for the facility is 5,561 lbs per year so the facility is regularly over its
annual allocation for TN. With the proposed expansion of the facility this load number may need to be further
addressed. Total Phosphorous is currently monitoring only in the permit with no limit. TP values over the
permit cycle averaged 3 mg/L with a maximum of 17.9 mg/L. With the potential for future expansion a TP limit
will likely be added to the permit based on regulatory requirements in the Neuse Basin and the facility will have
to assure that treatment processes will work to meet the limit.
Note: The current permit contains the Special Condition forAnnual Limits for Total Nitrogen. As a discharger less
than 0.5 MGD the Town has a TN allocation but does not currently have a TN limit. This section could be removed
from the permit. However, as noted earlier in the Fact Sheet, the Town has recently requested Speculative Limits
for expansion of flow to 0.6 MGD and 1.0 MGD. The Town is working to obtain funding to move toward application
for expansion. With potential expansion, the Annual Limits for Total Nitrogen will most likely be applicable to a
modified permit. To avoid any confusion that may be associated with removing the provision now and then putting
it back in with a potential expansion, the permit writer has left the special condition in the permit.
Treatment System Classification - With the potential for expansion discussed throughout the document it
should also be noted that treatment system classification will also likely be impacted. Based on existing
classification rules (15A NCAC 08G .0302) and nutrient treatment requirements it is likely that the classification
of the treatment system will be increased.
COMPLIANCE:
The Town has had twenty-three (23) NOVs and one NOD during the permit term along with Seven (7)
enforcement actions. Enforcements resulted in assessment of $ 4,293.75 in penalties and $349.78 in
enforcement costs. Over the permit cycle a large number of the monitoring violations noted were for frequency
violations (24 of 40) rather than exceedances. The main limits violations were for Flow (2), TSS (2), Fecal(2)
and BOD (2).

.15MGD. The assessment documents noted that degradation would occur, but not beyond that already
occurring with the existing discharge. The documents indicate that the Town was under and SOS at the time
of the requested assessment.
• May 26, 1982 - WLA for two discharge locations. The first location is the existing point on Beaverdam
Creek and the second is on Little River just below the dam. Instream flows are the same for the Beaverdam
location. For the Little River locations 7Q10(s) - 7.3; 7Q1O(w) - 19.2; 3OQ2 - 29.6. Both allocations are
given for a proposed discharge flow of 0.33MGD.

• September 4, 1986 - Change in Effluent Limits - This document goes through discussion of changes in BOD
and Ammonia limits for the Town's proposed WWTP upgrade. The limits had been lowered based on newer
instream flow information from USGS. This new information gave an estimate closer to the discharge point
Town of Princeton WWTP Fact Sheet
NPDES Renewal 2023 — July 18, 2023
Page 5

eliminating previous modeling estimates of a high amount of runoff volume. The Division indicted that
while the limits were more stringent, they may lead to additional federal funding for the complete design
that the town was seeking.
June 5, 1987 - Authorization to Construct (ATC) - This ATC allowed for the modification of the Town's
WWTP to include various components to expand capacity to 0.275MGD.
April 25, 1988 - Request for In -Stream Assessment - This request was related to a JOC. The Town was
under an SOC but was not able to meet the limits. Construction was ongoing to expand the facility but the
current capacity was still at 0.12MGD.
January 29, 1991- WLA - This WLA was done for 0.275MGD flow and resulted in the same limits as the
1986 WLA with the exception of Fecal numbers changing to 200#/100mL. The receiving stream is now
Little River and it is classified WS-III; NSW. This allocation notes that the facility has been doing Whole
Effluent Toxicity (WET) monitoring as well and that this will continue. The documents mention that the
facility has a choice between more stringent NH3-N limits and existing limits with Tox testing but since Tox
testing is already required the limits remained the same. It appears that WET requirements were added
through an Administrative Letter and based on toxicity concerns instream due to Chlorine levels from the
discharge back in 1988 (see WLA info for Dec 1993). The document notes that the facility may need
nutrient requirements in the future and that they appear to be handling instream DO monitoring incorrectly
(regional office will work with the Town on DO issue). The WLA also requires U/D monitoring for Temp,
DO, Conductivity, pH and Fecal. The document includes an attached letter to the Town on Total Residual
Chlorine changes and their potential need to make adjustments and be limited in the future.
December 13, 1993 - WLA - The limits in this WLA are slightly different than those from the previous WLA.

The document notes that the previous permit required TRC, TN and TP monitoring and this is maintained in
this permit. Instream monitoring for pH is no longer required. The document includes staff information
that indicates that the toxicity requirement was added as a result of the facility failing a random toxicity test
in 1988 (thought to be due to chlorine). The staff information also notes the discharge point relocation from
Beaverdam Creek in 1991 with a 2-mile effluent pipe to the Little River. Again, notes the possibilities for
TRC limit and required dechlorination in the future.

- Instream monitoring for Temp and DO; BOD and TSS require 85% monthly avg. removal.
- TN monitoring for concentration (2/month) along with monthly load and annual load.
- Instream monitoring for Fecal and Conductivity removed (policy for 100% domestic)
- Instream monitoring for Temp and DO increased to 3/wk (July - October) due to documented instream

- Monitoring for TN and TP increased to 2/month due to NSW requirements. Cover letter outlines
components of Neuse NSW rules and recommends evaluating cost of nutrient removal.
• November 16, 2001- Permit Modification to change the sampling type for NH3-N, TN and TP from grab to
composite.
• February 28, 2001- ATC for the installation of dechlorination (sodium bisulfite chemical feed system) and
flow proportional sampling.
• March 7, 2001- RRO Staff report on the ATC request
• January 11, 2002 - Engineer's Certification of completion construction associated with the February 28,
2001 ATC.
• March 13, 2002 - ATC for replacement of influent pump.
• October 4, 2002 - Correspondence with the Town on EMC required construction of dual clarifiers to replace
their dual boat clarifiers. The Town's consultant had sent information related to the construction of one
clarifier after the dual boat clarifiers.
Town of Princeton WWTP Fact Sheet
NPDES Renewal 2023 — July 18, 2023

• June 30, 2004 - Permit Renewal - At the time of this renewal the Town was in the process of getting an SOC
for BOD and TSS limit issues. The Town had not yet been able to replace the boat clarifiers as required by
the EMC. The facility had dealt with numerous permit violations over the permit term. EMC SOC WQS02-
012 was issued August 2003. The permit renewal added summer weekly average (WA) limits for NH3-N as
required by EPA regs. The permit documented the WA limit as being set at 2 times the monthly average of
12mg/L. However documentation noted a Division max of 35 mg/L. However, the permit was issued at 36
mg/L. The permit also added monitoring and reporting requirements for Total Flow; Total Kjeldahl
Nitrogen (TKN) , and Nitrate and Nitrite Nitrogen (NO3-N and NO2-N). TSS monitoring was increased to
3/week to address ongoing issues and be more representative of what was happening at various flows.
• March 11, 2005 - Speculative Limits - The Town requested speculative limits on potential upgrades to 0.6
MGD and 1.0 MGD flows. The limits for these two flows can be seen in the document in the 2005 folder in
Laserfiche. The document notes considerations for TN and TP loads based on the increased discharge flow
as well as the impact to treatment system classification. This issue is not addressed in the 2023 Speculative
Limits letter.
• May 19, 2008 - Permit Reissuance - This permit includes the addition of two clarifiers in the treatment
system components. The application indicates the boat clarifiers have been removed, but the RO staff
comments indicate that portions are still there and the component should remain in. The permit still has
the WA limit of 36 vs 35mg/L for NH3-N. The permit also lists TN monitoring as monthly rather than
2/month? The package still notes some ongoing compliance issues but seems operation has improved with
the additions to the treatment system. The permit includes a special condition outlining the TN allocation
for the permit.
• May 18, 2011 - ATC for the addition of a dual bank UV disinfection system.
• July 22, 2013 - Engineer's Certification for completion of the UV system.
• January 20, 2015 - Permit Renewal - The permit adds quarterly monitoring for mercury (Hg) to gather
information and also adds a footnote that the TRC limit applies only if the backup chlorine treatment system
is used. Permit still had the WA limit of 36 mg/L for NH3-N. eDMR language is added to the permit
conditions.
• October 15, 2018 - Permit Reissuance - Renewal included update of various language throughout the
permit along with addition of influent monitoring for BOD and TSS to assess the 85% removal requirement;
increase of TRC limit to 28µg/L; increased TN monitoring back to 2/month to be consistent with Neuse
requirements; changed mercury monitoring to annual; added Sections for TN Limits and for Mercury
Sampling. Permit maintained the 36mg/L NH3-N limit.
• May 19, 2021- Sewer Line Moratorium - Facility was shown in 2020 as exceeding 90% of 0.275MGD
capacity.
• June 25, 2021- Town response letter to Moratorium.
• July 28, 2021- Request from the Town for ATC for replacement of one manual bar screen with a mechanical
one and replacement of centrifugal grit removal device. BIMS shows the ATC approved November 2021 but
no documentation in Laserfiche or files.
• January 31, 2023 - Speculative Limits - see discussion above in this Fact Sheet under the Application
section.
PROPOSED PERMIT CHANGES:
• Updated eDMR requirements to be consistent with final EPA rule.
• Added or updated regulatory citations throughout permit as needed.
• Monitoring requirements for WET have been removed from the permit as this is a 100% domestic
discharge that has not had a failed WET test result in over 20 years.
• Footnotes in the effluent tables have been updated with current language and with removal of the WET
requirements.
• NH3-N summer limits modified based on updated USGS stream flow numbers and WLA spreadsheet and
given 18 month compliance schedule.
• Added Special Condition for Nutrient Re -opener in section A.(6.).
• Permit map information updated.

Mr. King,
Thanks for the reviews of the draft permit. The information included in the cover letter for the draft was intended to
simply convey that the renewal was moving forward based on your existing flow conditions as applied for in your 2022
application for renewal. Final decisions on the Town's expansion process, as stated in the January 31, 2023 letter, can
only be made after the Division receives and evaluates a formal permit application for the expanded discharge that
includes a detailed Engineering Alternatives Analysis. So nothing has really changed from that standpoint.
Hope this helps

The top sentence does seem to be correct. I thought we had terms worked out to expand the sewer plant and
they had given permission to seek funding for a new plant and to give the necessary permit to move
forward This letter states that they may not recognize any additional capacity.

Subject: RE: Draft Permit for Review - NC0026662 - Town of Princeton WWTP
Hey Bradley,
See my comments below. Hope you're having a good week so far!
Permit:
• Facility address is still highlighted yellow on the Supplement to Cover Sheet (I'm assuming because it doesn't
match up with the address on the Application or Factsheet)
• 1 didn't see any mention of an 18-month compliance period in the permit itself, only on the cover letter (and
factsheet). Maybe this is an older draft version?
• Condition A. (3) still includes the old Rule citation. Should be updated to cite 02B .0713
• The map's Latitude shows 38' instead of 35' and I believe the HUC should be 030202011603
Factsheet:
• BIMS and factsheet have differing 7Q10s. Looks like BIMS just needs to be updated with the new info you got
from USGS.
• In the monitoring data review table, you still have a comment for Winter ammonia. Wasn't sure if you wanted to
leave it in!
• I found a few instances where Word auto -corrected dechlorination to "dichlorination"
• Should you mention the 18-month compliance period in the 'Proposed Permit Changes' section along with the
modification of Ammonia summer limits?

Hey Kristin,
Hope you are doing well. I am working on the renewal for the Town of Princeton. At this point there has been no
further information on any expansion requests and they indicate it is a ways off, so we are just moving forward to renew
based on the existing flow of 0.275MGD. One question I wanted to run by you was related to the USGS flow numbers
that you were using in the Speculative Limits. I couldn't find their actual request document for the Spec Limits in
Laserfiche so I wanted to see if they are proposing discharge at a different location or at the same discharge point in
Little River. Since the USGS flow numbers are a bit lower than what had been shown previously in their permit info I
wanted to clarify this. It would lower their Ammonia number a good bit if I use the flows that you had. Do you know if
they were proposing the same discharge location and just got updated flow numbers for that point?
Thanks for any help you can give me on this. If you want to discuss it we can set up a Teams call.
Thanks,

Hey Bradley,
Apologies for the late reply. We're down to 1 senior NPDES inspector and 1 newbie Q. Stephanie Goss did the last
inspection at Princeton. A cursory review of the inspection report didn't reveal any outstanding issues. The inspection
was conducted as a sampling inspection.
For Brighton and Lassiter, the last inspections were conducted in 2019. These will likely be targeted for inspections the
next federal fiscal year. Both of these inspections were conducted by staff who are no longer with our unit.
Thanks for reaching out to our group as you initiate review of these permit renewals.

Hey Vanessa,

I just wanted to touch base on renewals that are coming up for me and get contacts in the region for any issues with
these.
• Town of Princeton WWTP — NCO026662 - I am starting the review of this renewal and wanted to see if you guys
have anything you wanted to pass along on the review. It does look like they have had a number of NOVs and
enforcements over the permit cycle. Also, they got Speculative Limits earlier this year for future expansions to
0.6 and 0.95 MGD. We haven't seen any actual expansion requests at this point. I have asked them for
information on their timeframe with this to see if we move forward or hold on this one.
• Town of Fuquay- Varina / Brighton Forest WWTP — NCO066150
• Aqua North Carolina / Lassiter Farm Subdivision WTP — NCO088714
Let me know who in the RRO I should be in touch with on these permits.

Mr. King
Based on the response about timing for expansion requests the Division will move forward with permit renewal at this
time under the current flow. There are still a number of steps ahead of you and your engineers in the process to
develop Engineering Alternatives Analyses, applications, etc. to assure that the expansion can proceed as planned. At
this time, it seems most prudent to move ahead with the renewal and you are your staff can submit the needed
information associated with permitting a potential expansion as information is developed.
I will be working on the draft renewal and hope to have it ready for public notice soon.

Michael/Bradley,
All that we can respond to is regarding expansion. The Town of Princeton received a SEARCH Grant from USDA Rural
Development to prepare a Preliminary Engineering Report (PER) to expand the Princeton WWTP from 275,000 GPD to
575,000 GPD. This has been submitted to USDA RD for approval. Once the approval is received, TRC will proceed with
applying for funding to expand the WWTP through USDA WEP program. It is also my understanding that Mayor Don
Rains is seeking funding through the NC Legislature as well. If funding is secured by the end of summer, it would take at
least one year to design and permit an expansion then another 18 months or more for construction.
I hope this information is helpful. You may want to check with Glenn Holland on the other information requested.
Sincerely,

MARLA ASHWORTH

Mr. King,
I am the permit writer assigned to handle the review of your permit renewal request for the Town's WWTP —
NC0026662. As I have started the review, I do have some additional information requests for you and I am also passing
along some information on our process for transmitting information electronically to permittees. Please review the
information below and provide responses as needed.
Expansion
I was copied earlier this year on a Speculative Limits Letter that the Town received concerning potential expansion of the
WWTP. At this point it does not appear that the Town has submitted any additional information (application, EAA, etc.)
associated with this issue. I just wanted to touch base and try to determine if you anticipate any request on an

expansion soon? If so, we can discuss whether we should hold off on the renewal to address these requests. If this is
not anticipated in the near term then we will move forward with the renewal request for the 0.25 MGD flow.
Contacts in Database
I have attached a document that shows contact information for this permit currently in our database. Please review the
information and provide us with any changes or updates that need to be made to this information.
Transmittal of Permit Information Electronically
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.
Please respond to me through email with verification that transmittal of your documents in an electronic manner is
acceptable to you. If you have any questions, please feel free to contact me.
Thanks for your assistance. Please let me know if you have any questions or need to discuss any issues. So, you know
my schedule, I am a part-time employee and my usual work schedule is Monday through Wednesday.
