FACILITY OVERVIEW:
This facility is 100% domestic waste and treats a subdivision serving a population of 1,892 people. The facility
has a permitted and as built flow rate of 0.1 MGD. The treatment system includes the following wastewater
treatment components:
• Bar screen
• Aeration basins with mixers and DO probes
• Clarifier with blower
• Chemical phosphorus removal
• Tertiary filters
• Flow meter
• Ultraviolet disinfectant
• Effluent pumps
• Back-up power generator

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 Aqua North Carolina, Inc. The annual average daily flow is indicated as
0.04 MGD over the last two years, so the facility is operating at well below its designed and permitted capacity.
The application indicates upcoming improvements with metal rehab scheduled for January 2025. The
application indicates discharge is to Upper Barton Creek, but the location of the facility on the map and previous
information in the permit file confirm that the discharge location to Lower Barton Creek is accurate. The
application also notes the facility location as on Gleneagle Drive but the BIMS database notes a location on
Baileywick Road. Permittee response on this issue is that the Baileywick address doesn't exist and it appears
Gleneagles wasn't extended as is should have been. The entrance to the WWTP is off of Baileywick but old
permits have said location is Gleneagles and it appears the applicant wants to maintain this location.
As part of the application request Aqua asked that the Division remove Whole Effluent Toxicity (WET)
requirements from the permit. Their request is based on the facility no longer using chlorine for disinfection
and having passed all toxicity tests during the permit cycle.
INSPECTION
The most recent inspections occurred on December 27, 2018 and was conducted by Wake County
Environmental Services. The inspection noted that the facility was being upgraded to begin nitrification and
was operating well. One note in the inspection report indicated that the exact location of the outfall needed to
be marked. The inspection report noted modifications in the aeration basins to create anoxic conditions for
denitrifications (new mixers, DO probes and blower).
Reviewing other file information shows that in response to the 2018 permit changes that included nitrogen
limits, the facility initiated a pilot process to promote nitrogen removal. This pilot process became final with a
2019 ATC for the finalization of the mixers, blower and DO probe noted in the inspection report.

REVIEW OF PERMIT LIMITS:
Flow - The facility is operating on average at around 40% of the flow allowed by the permit. None of the 59
monthly average values was above 0.056MGD.
BOD / TSS / Fecal - The only limit violation this cycle was one exceedance for fecal coliform. This value was
well above any other value for fecal reported during the permit cycle.
Ammonia (NH3-N) and ToxicU - This permit has had both ammonia and toxicity limits since the 1991 WLA.
The 1991 WLA had looked at setting NH3-N limits at 1.3 and 3.1 mg/L, but the permittee instead asked for the
existing limits of 9 and 18 mg/L with the addition of WET requirements. These requirements have remained in
the permit. Over time the permittees (prior to Aqua) had asked for removal of the toxicity requirements in the
permit. During those reviews it was determined that the facility had toxicity test failures and those failures
were not during times when other parameters like ammonia showed any issues to potentially cause the failures.
So, the WET testing was maintained in the permit. With this application Aqua has requested review of the WET
requirements in this permit for removal.
Over the last permit cycle the facility did not have any failed WET test results. The Aquatic Toxicology Branch
has been contacted about the removal of WET testing and feels that for this facility, as a 100% domestic
discharger, the WET requirements can be removed from the permit. The Regional Office was also asked for
input. This draft proposes removal of the WET requirements. Along with this change the permit will include
more stringent Ammonia limits consistent with the WLA spreadsheet analysis, implementation of revised
ammonia criteria and the Division's policy for small WWTP of this type. The Waste Load Allocation spreadsheet
for this discharge calculated NH3-N limits of 1.8 mg/L for summer and 3.1 mg/L for winter. However, Division
policy has established that for small discharges (< 1 MGD) the best available treatment technology for these
facilities leads to monthly average limits no lower than 2 mg/L -summer and 4 mg/L - winter. Limits in the
permit will be set as follows:
Monthly Avg
Daily Max
Frequency
Type
Location
NH3-N - Summer
2 m L
10 m L
Weekly
Composite
Effluent
NH3-N - Winter
4 m L
20 m L
Weekly
Composite
Effluent
The data reviewed for this renewal would indicate that the facility can meet these permit limits. During the
previous permit cycle, evaluating the data with these limits resulted in no violations over the permit cycle.
The permittee was informed of the removal of WET requirements and adjustment of the NH3-N limits in an
email on March 14, 2023. After hearing about the NH3-N limits the permittee responded that they would like to
rescind their request for WET removal. Division staff responded that with the new ammonia criteria and input
from EPA on the use of action level standards in the place of chemical limits we could no longer allow WET
requirements in leu of more stringent NH3-N limits.
Nutrients
This permit was renewed in 2018 with nutrient limits - concentration, monthly and annual load limits. The
facility worked to add treatment processes to address nutrient reduction and requested a modification to the
permit that was issued in 2019. The 2019 modification set up a bubble permit that works with Aqua's
Hawthorne WWTP (NC0049662) to establish nutrient allocations and load limits that are set as combined mass
load limitations for the two plants. In the year prior to the modification the permittee had multiple violation
and enforcement actions for TN and TP concentration violations. These concentration limits were removed as
part of the 2019 permit modification.
The permittee has been reporting some of the nutrient data inaccurately in the eDMR system. The permitee has
reported the nitrogen and phosphorus annual loads, QY600 and QY655, on a monthly basis. Each month the
value is reported identical to the monthly value (QM600 and QM655). They should be reporting the QM values
monthly and then reporting the total annual load (QY values) in the December DMR only. The permittee is also
Wildwood Green WWTP Fact Sheet
NPDES Renewal 2023 — March 28, 2023
Page 3

required to report the total combined annual load number for nitrogen and phosphorous as part of the
December DMR for the Hawthorne (NC49662) facility as part of a separately established permit outfall in the
Hawthorne permit. The permittee reported this data correctly in 2019 and 2020 but did not report the data at
all in 2021 and 2022. The permittee also had one DMR (July 2022) that reported TN and TP numbers that were
very high and subsequently modified the DMR in January 2023. However, the January 2023 correction was
added to the eDMR system but never submitted appropriately in the system. So, the incorrect data is still the
data found in the BIMS system. Permit staff accounted for these corrections in the review of permit data. The
permittee was made aware of these issues in an email as part of this renewal review and is working to correct
these.
COMPLIANCE:
The facility had one NOV for a daily max fecal violation in 2020 and also an NOV for missing a WET test in 2022.
The WET test was completed in a subsequent month. In 2018 (as noted above) the facility had a number of TN
and TP concentration violations and enforcements, but the concentration limits were removed from the permit
in the 2019 permit modification.

Also requires TRC monitoring. This WLA had proposed lower NH3-N limits (1.3/3.1) or to maintain the
existing 9/18 limits with WET testing. Permittee chose WET test alternative.

Heater Utilities requested removal of the WET requirements and instead strengthen NH3-N limits. DWQ
reviewed and found that there had been toxicity failures at times when neither TRC or NH3-N data showed
any potential issues. Due to this, DWQ denied the request to remove WET and recommended that the
permittee look for and address the source of toxicity and then, with one full year of compliance with the Tox
requirements they could request removal again. With Tox remaining, NH3-N limits remained at 9/8 rather
than being reduced to 2/4.
• September 15, 2000 ATC for installation of a UV disinfection system
• June 21, 2001 Engineer's Certification for completion of the UV disinfection system
• 2003 Permit Renewal - Heater again requested removal of the WET requirement. DWQ review again
showed that there had been toxicity failures and at the time of the failures NH3-N levels did not show a
problem. WET requirements were maintained in the permit without decreased NH3-N limits. Added daily
max limits for NH3-N to meet EPA requirements. Limits set at 35mg/L for both summer and winter (5:1
ratio with 35 as the Division cap). Notes the NSW rules and that the facility will be subject to nitrogen limits
in the next permit cycle. Fact Sheet seemed to be leaning to removing WET testing but then the facility had
a failed test in Aug 2003. Monitoring for TKN and NO2-N+NO3-N required to be reported separate in DMR.
Influent monitoring for BOD and TSS deleted in a permit correction letter.
• 2008 Permit Renewal - At this time Aqua has become the permittee. There is no indication in the file that
Aqua requested any review of the WET requirement. The staff report for this renewal noted that there had
been periodic toxicity issues not related to NH3-N. Major changes in this permit are the addition of nitrogen
requirements in keeping with the NSW rules. This included special conditions for Nitrogen calculations,
Annual Limits and Load Allocation. Special condition also added on temporary disinfection. The permit
included a condition for a Wastewater Management Plan including a mechanical evaluation of the facility.
The Fact Sheet had a lot of discussion about the facility moving to Class III and associated monitoring
changes but ultimately the facility stayed Class II.
• 2013 Permit Renewal - No discussions about removal of WET. Permit adds in the parameter codes and also
updated the TRC footnote language about compliance threshold.
• 2018 Permit Renewal - Permit renewal added monthly average TN limit of 8mg/L and an annual average
limit of 5.5mg/L. TP monthly average was lowered to 1.0 mg/L and a TP annual average limit of 0.5mg/L
was added. This permit also added rule citations and language for electronic submittal of DMRs. There was
no discussion about WET requirements.
• February 2018 Modification - This modification was issued in response to the permittee's request for a time
extension to meet TN and TP limits. The average annual limits for TN and TP were set as taking effect
January 1, 2019. The quarterly average limit for TP was set to expire December 31, 2018.
• March 2019 Permit Modification - This modification was issued in response to the permittee's request for a
modification that allowed for mass load combined (bubble) permit limits for this permit and their nearby
Hawthorne WWTP (NC0049662). The permit changed the effluent limits page to monitoring only for TN
and TP and established Special Conditions pages to outline Combined Limitations for the Wildwood Green
and Hawthorne WWTPs. The permit also established changes in special conditions to set TN and TP
Allocations. No discussion about WET requirements.
• August 28, 2019 - ATC for finalization of pilot upgrades to the treatment system for increased nitrogen
removal. Upgrades consist of the addition of four mixers to the aeration basins, connection of a dedicated
blower for the clarifier and installation of DO probes in the aeration basins.
• September 5, 2019 Memo to File on Transfer of Unavailable TN Allocations. This memo summarizes a
meeting between Aqua staff and DWR staff on September 3, 2019 to discuss transferring TN allocations
from Hawthorne and Wildwood Green WWTPs to Aqua's Neuse Colony facility. The Neuse rules don't
provide for existing facilities to increase their limits and expects them to take steps to meet their assigned
limits. Aqua could transfer TN allocation to Neuse Colony but it could only be used when the facility
Wildwood Green WWTP Fact Sheet
NPDES Renewal 2023 — March 28, 2023
Page 5

expands beyond 0.75 MGD as currently permitted. It did not appear likely that Aqua would benefit from a
transfer.
PROPOSED PERMIT CHANGES:
• Updated eDMR requirements to be consistent with final EPA rule.
• Added or updated regulatory citations throughout permit as needed.
• Removed WET from the permit and added in more stringent NH3-N limits of 2/10 summer and 4/20
winter.
• Permit map information updated.
• Added Special Condition for Nutrient Re -opener.

Hey Bradley — The only comments received were:
1. Chemical for phosphorus removal is sodium aluminate not ferric sulfate.
a. Can we just say chemical phosphorus vs specifying the chemical?
Also Hawthorne has a flow EQ basin and influent basin listed. Are they not the same?

Hi Bradley -
I was out of the office that week, and I was under the impression someone else responded.
Yes, we have received the drafts and are under review by operations staff. I will let you know if we have any comments
or concerns.
Wildwood Green —Yes, it has backup chlorination. It is rarely used but it's available.
Thank you, and apologies on the delayed response.
Best regards,

Amanda,
Attached are the draft permit renewals for these two WWTPs. These permits are going to public notice as
drafted. Please review and let me know if you have any questions or comments. On the Wildwood Green WWTP could
you verify whether or not there is backup disinfection (Chlorine). There has been some language in the permit to
include TRC limits if chlorine is used and discuss temporary disinfection. Backup disinfection was not mentioned in the
application though. If this is not the case then we can remove that reference.
Please respond to this email to let me know that you received the two permit files and were able to read, download
and print the files for your records.

Maureen,
There was discussion about the classification in the permit files for each of these. There is a brief discussion of this in my
Fact Sheets. For Hawthorne there was a January 2000 letter in the file from DWQ that classified the system as Class
II. For Wildwood Green there was discussion about the proper classification in the 2008 permit renewal. Ultimately it
was given Class II status instead of Class III. I can't remember if there was a letter in the file on this one or not. I'm in
the office today and did not bring the files for these but I'll check back through about that and get back to you. Is there
anything that has happened recently that would change these to Class II?
Thanks

Just wanted to pass along that these two permits have gone to notice. I know you had indicated some comments on the
components list. I had responded to your last email to try and get clarification on those changes since it looked like you
hadn't attached the file where you made the changes. Even though that didn't get in the drafts we can make
appropriate changes in the final permits.
Thanks for your help with these.

Amanda,
Thanks for the updated info and looking into the DMR issues. On the Ammonia/WET testing issue I guess I should have
mentioned a few other pieces. We had another renewal (Briarwood I think) that noted the Division is implementing
updated Ammonia criteria that is based on EPA input that we can no longer use action levels to replace chemical limit
requirements. In the past we had allowed people to pick adding toxicity over more stringent ammonia limits. We can
no longer do this in our permits and have to use the more stringent chemical limit requirements. So, I think we will have
to implement the required ammonia limits. Looking at the data from the previous permit cycle and using the proposed
limits (2/10 — summer and 4/20 -winter) it looks like your facility would not have had any limit violations.

Hi Bradley,
The DMR's are generated by our compliance software. For programming purposes, it lists the annual loads monthly. I
have advised the operator to remove that column moving forward. The monthly loads for each facility is correct. Please
ignore the annual loading calculations for each facility. Operations will be revising the December DMRs to include the
annual loading requirements for Wildwood Green. Hawthorne appears correct on my end, but I have also asked they
verify prior to your review of that facility.
With respect to the WET requirement, given the information regarding the ammonia limit, Aqua is requesting rescission
of the request to remove the WET testing requirement.
Thanks,
Amanda

Hi Bradley,
Doing well. Hope you are!
Answering the first 2 questions. I will need to work with operations to review the others.
The address listed on the application is the address listed on prior permits. See below.
a. When I searched for 1899 Baileywick, the address is not either listed or it is not the WWTP. Looking at
old aerials, it appears that Gleneagles Drive should have been extended and utilized as the entrance to
the WWTP; however, it is not. Entrance is off of Baileywick at intersection with Old Creedmore Rd. I
cannot locate a street address for either Baileywick or Gleneagles.
Upper Barton — Mistype from Hawthorne. Yes, its Lower Barton.

Amanda,

Hope you are doing well! I just wanted to touch base on the Wildwood Green and Hawthorne permit renewals. I am
currently working on the permit renewal reviews for each of these facilities. Since they are connected with the nutrient
loading requirements I want to complete and notice them at the same time. I have gone through the Wildwood Green
renewal and started on Hawthorne. I had a couple of issues to run by you guys based on where I'm at currently. I may
have additional issues as I work through the Hawthorne renewal but wanted to go ahead and send these along.
• On the Wildwood Green application, you indicate the facility address as Gleneagles Drive but in our system, it
shows as 1899 Baileywick Road. Could you verify the location for us. If it is Gleneagles is there an address
number as well?
• The Wildwood Green application indicates the discharge is to Upper Barton Creek, but it appears that our
records from before are accurate in showing discharge to UT to Lower Barton Creek.
• Wildwood Green submitted a DMR correction for your July 2022 data submittal. The correction was entered in
eDMR in January 2023. The data was certified in the eDMR system but was never submitted. The data needs to
be Submitted in eDMR before the correction can be processed and the data updated.
• For both Wildwood Green and Hawthorne, it appears that your monitoring data for nutrient loads is being
reported inaccurately. Your permits require submittal of monthly loads for TN and TP (QM600 & QM655) as
well as an annual load for each (QY600 & QY655). Your DMRs show that you are reporting the QY values each
month and reporting the same values as the monthly (QM) values. You should be reporting the QM values
monthly and the QY values only in the December monitoring report for each year showing the total annual load.
• For the Hawthorne permit you are also required to report combined annual nutrient loading for the Wildwood
Green and Hawthorne facilities using a separate outfall. Looking at the data it appears that you may not have
submitted this annual load for 2021 or 2022. Please check this and make the corrections if needed.
• For Wildwood Green you had requested review of WET testing requirements for potential removal from the
permit. It does appear that we will be able to grant this request and remove WET requirements. Please note
that with this change we will also update the ammonia limits in your permit. This will result in lower limits for
this parameter.
• 1 have attached Contact Information downloads from our system for each of the facilities. Please review this
information and let us know of contact corrections that should be made and any contacts that should be
removed, etc.
• You might also hear from Raleigh Regional Office staff on the monitoring issues noted above.
As with previous permits over the last few years, I will plan to submit drafts and the final permit do you electronically
unless you request hard copies.
Thanks for your attention to these requests. I'll be back in touch if there are other issues as I continue my review.

Cheng,
On the July DMR for Wildwood Green, I think they did enter a corrected DMR in January 2023, but it never actually got
submitted in the eDMR system. They certified it so you can see it in eDMR but because they never submitted it the data
never made it into the system and got pushed to BIMS. I can talk with them about that issue if you want.

Bradley is correct, Aqua needs to report monthly TN (QM600) TP (QM665) loads each facility's DMR, and only report the
combined annual TN (QY600) and TP (QY665) on Hawthorne's December DMR (Permit Conditions Part I A(3). C.), and
they have been doing that (I think they reported the combined loads on Hawthorne's December DMRs) , I checked their
2022 data, the final numbers were not correct according to my calculation though, still well less that the annual TN and
TP limits. I will ask Aqua to amend Wildwood Green's July 2022 DMR (QM600 and QM665 were way off because total
monthly flow was calculated wrong) and check their annual load numbers, and also let them they only need to report
annual loads on Hawthorne's December DMR. Please let me know if you have any questions, thanks.

Hey Stephanie,
I am currently reviewing the permit renewals for these two facilities. They have bubble permits that tie the two
together with TN and TP loads. I noticed that you recently inspected the Hawthorne facility so I thought I'd reach out
about a couple of issues monitoring wise on these two. I'm not sure if you are familiar with the Wildwood Green facility
or not but thought I'd check.
On their monitoring I just wanted to verify that what I think I'm seeing is correct. Sometimes I miss some things on the
reported data and you guys help to straighten me out! So before I comment to Aqua I want to run this by someone in
the regional office. For both of these facilities they are reporting annual load numbers for TN and TP (QY600 and
QY665) on a monthly basis. Most months they are reporting the same number in the QY data as the monthly TN and TP

(QM6OO and QM665) load values. I think they should only be reporting the QY values in December? Looks like in
December they often are reporting a different QY value that seems to reflect an annual number. Also, for the
Hawthorne plant it looks like they haven't submitted their Combined Total TN and TP annual values for 2021 or
2022. These are supposed to be submitted under a different outfall number (CO1). Maybe I'm mossing something on
these?
Thanks for any input on these. Let me know if you have any other comments about these two renewals.

This is consistent with our tox strategy. With this being a domestic facility and having a consistent record of
passing their tox then the tox can be removed. We do have one domestic facility that still has a tox in the
permit but it is monitoring only. Town of Parkton has not consistently passed their tox. I would be in
agreement to remove the tox requirement for Wildwood Green.

Subject: Permit Renewal for Wildwood Green WWTP - NCOO63614
Hey Guys,
I am working on the permit renewal for this permit and had a question about Tox for this one. Aqua has asked if they
can have tox removed from the permit. For these domestic dischargers we have been looking at removing tox where it
was included in the past in leu of ammonia limits. This is in keeping with EPA's call on these types of limits and our need
to use the chemical requirements (2016 Memo). For this one in particular they had asked a number of years ago to
remove tox and go with increased ammonia limits, but in previous reviews we had found that they were failing tox and
there was no correlation with high ammonia numbers. Looking at the most recent data it looks like it has been quite a
while since they failed a tox test. We are considering removing tox and giving them lower ammonia. How do you guys
feel about that change. Relevant page from most recent tox results is included.
Vanessa, If you guys have any other comments on this one please let me know about those as well. This is a bubble
permit with Hawthorne WWTP (NCOO49662) so I may pick that one up also and try and review these two together. So
let me know if you have any input on Hawthorne as well.
Thanks

Amanda,
Just wanted to touch base with you on this issue with Wildwood Green. Looks like this one is in-house for renewal (just
came in). We will review this issue as part of the permit renewal.

Given that it is 100 domestic, it may not need Tox. I reviewed the last fact sheet. It was mute on the
subject. Given that this is an old permit, I have copied the oldest person I know (Bradley) on this email to see
if he can review the file further back to see when that was added and what the rationale was at the time.
By the way, I will pay for the old joke.

We will get back to soon.

John — Reviewing the Wildwood Green permit application, and question for you... Why does Wildwood have Chronic Tox
requirements? Is it basin specific?
Appreciate any information you can provide.
Thanks,
Amanda

Hi John —

Following up regarding Salem Quarter and Briarwood. I forwarded the details of our conversation to operations and
engineering. I did locate where we started a project in 2019 to address the bar screen at Briarwood, but somehow it did
not get awarded. We have a compliance management tracking system that was brought online in 2020, and both
projects have been assigned and will be tracked to ensure this does not occur again. Engineering is reaching out to
contracted engineer firms for design, and I should have additional information in a couple of weeks.
With respect to auditing other locations, we already have a permit review process in our Central and Eastern regions
have requested the Western Region's assistance in developing a similar model. The Kernersville office has a new
supervisor, and he and I have scheduled time to visit each of his facilities to begin the process.
I will be in touch with additional information as its available.
Thank you,
Amanda Berger
