EXPEDITED FACT SHEET - NPDES PERMIT DEVELOPMENT
NPDES Permit: NCO073318
2023 Renewal
This form must be completed by Permit Writers for all expedited permits which do not require full Fact Sheets.
Expedited permits are generally simple 100% domestics (e.g., schools, mobile home parks, etc.) that can be
administratively renewed with minor changes, but can include facilities with more complex issues (Special
Conditions, 303 (d) listed water, toxicity testing, instream monitoring, compliance concerns).

FACILITY OVERVIEW:
This facility is 100% domestic waste and treats a subdivision serving 156 residential connections and a
population of 378 people. The facility has a permitted flow of 0.2 MGD and as built flow rate of 0.05 MGD. The
treatment system includes the following wastewater treatment components:
• Influent pump station
• Influent bar screen
• Surge basin
• Aeration basin
• Sludge holding chamber
• Dual clarifiers
• Chemical phosphorus removal and pH adjustment
• Tablet chlorination
• Tertiary filter
• Tablet de -chlorination with post -aeration

APPLICATION
The application does not indicate any changes in the facility or treatment since the last modification of the
permit in 2018. The treatment system is operated by Clarke Utilities, Inc. The annual average daily flow is
indicated as 0.029 MGD over the last two years, so the facility is operating at well below its designed and
permitted capacity.
INSPECTION
The most recent inspections occurred on February 2, 2023. Recent DMR violations were discussed and the
report noted that the sludge holding tank was full, but was being pumped within the next week. The inspection
did not note any issues of concern with the facility.

The data reviewed for the renewal is from February 2018 through January 2023.
REVIEW OF PERMIT LIMITS:
Flow - The facility is operating on average at around 58% of the as -built flow allowed by the permit. None of
the 60 monthly average values was above 0.034 MGD. These data assessments included removing one outlier
value of 344 MGD reported in December 2022. This value was four orders of magnitude higher than other
reported values and was obviously inaccurate.
BOD / Fecal- There were five violations of BOD and Fecal limits with two of these resulting in enforcement
actions.
TSS- The were no violations for TSS in this permit cycle.
Ammonia (NH3-N)- There were four violations of NH3-N limits. Two of these violations led to enforcement
actions. The Waste Load Allocation spreadsheet included in this Fact Sheet shows allowable NH3-N limits that
Whippoorwill Valley WWTP Fact Sheet
NPDES Renewal 2023 -April 11, 2023
Page 2

are a bit higher than those included as limits in the permit. The 2 & 4 mg/L limits in the permit are a result of
previous modelling efforts that assessed overall impacts to the surface waters and will, therefore, remain in the
permit.
Nutrients
Total Nitrogen load numbers over the permit cycle included a maximum annual load of slightly over 440 lbs.
This annual load is well below that discharge allocation load of 4044 lbs. Total Phosphorous numbers did
include two quarterly values that exceeded the 2 mg/L limit. These values resulted in one NOV and one
enforcement action. The permit effluent tables previously included an eDMR code of 00600 for the TN loading
numbers. These codes have been corrected to QM600 for monthly load and QY600 for annual load.
COMPLIANCE:
This facility had twelve (12) violations during the permit term. Five of these violations lead to enforcement
actions with penalty assessments. The enforcement actions totaled $1,783.66 with $1,501.50 in penalties and
the remainder in enforcement costs. The permittee has failed to pay the last three of these actions with pending
amounts of $1,001.50 in penalties and $202.16 in enforcement costs still owed ($1203.66 total).

The document discussed a recommendation that this facility tie on to the Wake Forest WWTP, but the
owner provided information that he had already talked with the Town about another WWTP (Deer Chase)
in close proximity and the Town was not open to the connection.
September 11, 1990 - Authorization to Construct (ATC) for a 50,000 GPD extended aeration treatment plant
with Bar screen, equalization tank, aeration tank, phosphorous reduction chemical feed system, dual
clarifiers, sludge holding tank, flow recorder, tablet chlorinator with contact chamber, tertiary filtration
units, post -aeration, rip -rap aerator, pipes, pumping, etc.

Permit also required TN monitoring and reporting (2/month) for concentration plus monthly load and
annual load reporting. Instream conductivity and fecal monitoring was removed from the permit. The
permit included a special condition for the calculation of monthly and annual TN mass loads. In the cover
letter for the permit the Division outlined new nutrient requirements based on the newly issued NSW rules.
The facility was advised to begin looking at treatment options for nitrogen reduction. The permit's TP
requirements maintained the 2 mg/L quarterly limit but changed monitoring from quarterly to monthly
with the quarterly average being the average of samples collected during the calendar quarters (January -
March, etc.). This permit, along with others in the Neuse Basin, was held for a period of time while nutrient
issues were addressed in the basin.
• June 19, 2000 - Permit modification to reduce instream monitoring from 3/week to weekly for BOD, TSS,
NH3-N, pH, TRC, DO and fecal in response to correspondence from the Technical Assistance and Certification
Unit indicating the facility should be classified as a Class II treatment system.
• June 25, 2001 - Permit modification to adjust instream monitoring to weekly based on the facility's
designation as a Class II system.
• October 3, 2003 - Permit Renewal. This renewal added daily maximum limits for NH3-N of 10mg/L summer
and 20mg/L winter and modified the TRC limit for the 0.05 MGD flow to 28 µg/L. The permit included
addition of a special condition addressing Annual Limits for TN. The downstream monitoring location was
changed in response to the permittee's request to SR 2044 (Ligon Mill Road).
• January 30, 2004 - Permit modification to make monitoring frequencies for TN and TN components
consistent at 2/month.
• April 13, 2004 - Permit Name/Owner Change from Ira D. Lee and Associates to Clarke Utilities, Inc.
• April 14, 2008 - Permit Renewal - This renewal added a special condition for Total Nitrogen Allocations as
assigned by rule 15A NCAC 2B .0234. The permit also includes updates to the treatment system
components in the Supplement to Permit Cover Sheet.
• July 12, 2013 - Permit Renewal - This renewal does not include the previously added Special Condition on
Annual Limits for Total Nitrogen. The condition was removed because the permit does not include TN mass
limits. TP monitoring frequency was changed to 2/month to be consistent with other nutrient monitoring
requirements. TN was already set at 2/month. The cover letter for this permit noted Smith Creek being
listed as impaired with general language for impaired waters.
• January 6, 2018 - Permit Renewal - This renewal added the electronic submission language and added
regulatory citations.
• January 24, 2019 - Division letter to permittee to note that the January 2018 cover letter for the permit
inaccurately noted that TP had been changed to monitoring only. This was not the case; the permit
maintained the 2.0 mg/L limit and the cover letter was just in error.
PROPOSED PERMIT CHANGES:
• Updated eDMR requirements to be consistent with final EPA rule.
• Added or updated regulatory citations throughout permit as needed.
• Language in paragraph 2 of the Supplement to Permit Cover Page has been adjusted to outline
requirements prior to operating at the 0.20 MGD level.
• eDMR codes for BOD, TSS, NH3-N, TN and TP updated to replace initial 0 with C. Added code for Total
flow - 82220.
• eDMR codes for TN load have been corrected to note QM600 for monthly and QY600 for annual load.
• Footnotes in the effluent tables have been updated with current language where needed.
• In section A.(2), the effluent table for the 0.20 MGD flow, the footnotes were adjusted to correct incorrect
references.
• Permit map information updated.
• Added Special Condition for Nutrient Re -opener in section A.(5.).

Wren, Cynthia,
Is it too late to get these public noticed this week? Looks like they didn't go with the notices on May 2"d. Two permits
are Clarke Utilities permit renewal for Deer Chase WWTP (NC0063746) and Whippoorwill Valley WWTP
(NC0073318). The notice language has been updated in Access. I emailed the drafts to Joel Clarke already for his review
last week.

Hey Bradley,
Sorry for getting this back to you on public notice day. I only found two minor errors. It looks great otherwise! Excellent
job. Q
-Incorrect sub -basin number in Permit (Supplement to Cover Sheet) and Factsheet (Facility/Stream Info box)
-In your Factsheet (File History Review), for the note dated Jan 24, 2019, 1 think it's supposed to say "TP" instead of "TN"
for the 2.0 mg/L limit.
Hope you have a great week!

Subject: Permit Renewals for Clarke Utilities permits - Whippoorwill Valley (NC0073318) and Dear Chase (NC0063746)
Hey Mitch,
Hope you are doing well. I am working on permit renewals for these two Clarke Utilities facilities and noticed that you
had done the most recent inspections earlier this year. I just wanted to get in touch and see if you had any comments
about the renewals that you wanted to pass along. I have a draft for Whippoorwill Valley in the works now and have
done a little work on Deer Chase. I hope to send these to you for review soon and then on to notice. One thing I
wanted your input on for Deer Chase is their WET requirements. It looks like they have been consistently passing these
and recently the Aquatic Tox staff have indicated that we should remove WET requirements for these 100% domestic
discharges if there are no noted problems. Do you have any concerns about potentially eliminating WET requirements
for Deer Chase?

Thanks for tour help.

Mr. Clarke,
After our call yesterday I checked with other staff in the central office and our Raleigh Regional Office and was not able to
track down permit renewal submittals for either of these permits. You mentioned talking with someone I think about
getting your submittal routed to the right person. Do you remember who you talked with?
At this point it would be helpful if you could forward copies of the applications if you have copies you could send.
Thanks

WWTPs

Mr. Clarke,
The NPDES discharge permits for the two WWTPs mentioned in the Subject line above expire on January 31, 2023. At
this point our records do not show receipt of permit renewal applications for either of these facilities. Renewal
applications are due 180 days before expiration of the current permit. This deadline is established in Federal and State
requirements [33 USC 1251, 40 CFR 122.21 (b), and 15 NCAC 21-1.0105 (e)] and in the conditions of your exiting permit
[Part 11 Section B. Paragraphs 9. and 10.] Discharge of wastewater without a valid permit is a violation of Federal and
State requirements.
If no renewal application is received, the Division is required to make the permit Inactive. If no response is received by
1/31/2023, the Division may take action to make the permits Inactive.
The renewal application form (Modified EPA Form 2A) can be found here:
https://deq. nc.gov/water-quality/aquifer-protection/afo/permits/2021-npdes-modified-epa-form-2a/download
Information on the permitting and renewal process can be found at:

Please complete and submit the form to:
Ms. Wren Thedford

Only the completed original form is required — no extra copies need be submitted.
Thanks for your attention to this matter.
