This letter transmits a Notice of Violation and assessment of civil penalty in the amount of $1,462.27 ($1,330.50 civil

This assessment is based upon the following facts: a review has been conducted of the Discharge Monitoring Report

Based upon the above facts, I conclude as a matter of law that Chatham Park Investors LLC violated the terms, conditions or
requirements of NPDES WW Permit No. NCO020354 and G.S. 143-215. 1 (a)(6) in the manner and extent shown in
Attachment A. In accordance with the maximums established by G.S. 143-215.6A(a)(2), a civil penalty may be assessed

1 330.50 TOTAL CIVIL PENALTY
131.77 Enforcement Costs
1 462.27 TOTAL AMOUNT DUE
Pursuant to G.S. 143-215.6A(c), in determining the amount of the penalty I have taken into account the Findings of Fact and
Conclusions of Law and the factors set forth at G.S. 14313-282.1(b), which are:
(1) The degree and extent of harm to the natural resources of the State, to the public health, or to private property
resulting from the violation;
(2) The duration and gravity of the violation;
(3) The effect on ground or surface water quantity or quality or on air quality;
(4) The cost of rectifying the damage;
(5) The amount of money saved by noncompliance;
(6) Whether the violation was committed willfully or intentionally;
(7) The prior record of the violator in complying or failing to comply with programs over which the Environmental
Management Commission has regulatory authority; and
(8) The cost to the State of the enforcement procedures.
Within thirty (30) days of receipt of this notice, you must do one of the following:
(1) Submit payment of the penalty, OR
(2) Submit a written request for remission, OR
(3) Submit a written request for an administrative hearing
Option 1: Submit payment of the penalty:
Payment should be made directly to the order of the Department of Environmental Quality (do not include waiver
form). Payment of the penalty will not foreclose further enforcement action for any continuing or new violation(s).
Please submit payment to the attention of:
Wastewater Branch
Division of Water Resources
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
Option 2: Submit a written request for remission or mitigation including a detailed justification for such
request:
Please be aware that a request for remission is limited to consideration of the five factors listed below as they may
relate to the reasonableness of the amount of the civil penalty assessed. Requesting remission is not the proper
procedure for contesting whether the violation(s) occurred or the accuracy of any of the factual statements contained in
the civil penalty assessment document. Because a remission request forecloses the option of an administrative hearing,
such a request must be accompanied by a waiver of your right to an administrative hearing and a stipulation and
agreement that no factual or legal issues are in dispute. Please prepare a detailed statement that establishes why you
believe the civil penalty should be remitted, and submit it to the Division of Water Resources at the address listed below.
In determining whether a remission request will be approved, the following factors shall be considered:
(1) whether one or more of the civil penalty assessment factors in NCGS 14313-282.1(b) was wrongfully
applied to the detriment of the petitioner;
(2) whether the violator promptly abated continuing environmental damage resulting from the violation;
(3) whether the violation was inadvertent or a result of an accident;
(4) whether the violator had been assessed civil penalties for any previous violations; or
(5) whether payment of the civil penalty will prevent payment for the remaining necessary remedial actions.
Please note that all evidence presented in support of your request for remission must be submitted in writing. The
Director of the Division of Water Resources will review your evidence and inform you of his decision in the matter of
your remission request. The response will provide details regarding the case status, directions for payment, and
provision for further appeal of the penalty to the Environmental Management Commission's Committee on Civil Penalty
Remissions (Committee). Please be advised that the Committee cannot consider information that was not part of the
original remission request considered by the Director. Therefore, it is very important that you prepare a complete and
thorough statement in support of your request for remission.
In order to request remission, you must complete and submit the enclosed "Request for Remission of Civil Penalties,
Waiver of Right to an Administrative Hearing, and Stipulation of Facts" form within thirty (30) days of receipt of this
notice. The Division of Water Resources also requests that you complete and submit the enclosed "Justification for
Remission Request."
Both forms should be submitted to the following address:
Wastewater Branch
Division of Water Resources
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
Option 3: File a petition for an administrative hearing with the Office of Administrative Hearings:
If you wish to contest any statement in the attached assessment document you must file a petition for an administrative
hearing. You may obtain the petition form from the Office of Administrative Hearings. You must file the petition with
the Office of Administrative Hearings within thirty (30) days of receipt of this notice. A petition is considered filed
when it is received in the Office of Administrative Hearings during normal office hours. The Office of Administrative
Hearings accepts filings Monday through Friday between the hours of 8:00 a.m. and 5:00 p.m., except for official state
holidays. The petition may be filed by facsimile (fax) or electronic mail by an attached file (with restrictions) - provided
the signed original, one (1) copy and a filing fee (if a filing fee is required by NCGS §15013-23.2) is received in the
Office of Administrative Hearings within seven (7) business days following the faxed or electronic transmission. You
should contact the Office of Administrative Hearings with all questions regarding the filing fee and/or the details of the
filing process.

Raleigh, NC 27699 6714
Tel: (919) 431-3000

One (1) copy of the petition must also be served on DEQ as follows:
Mr. William F. Lane, General Counsel
Department of Environmental Quality
1601 Mail Service Center
Raleigh, North Carolina 27699-1601
Please indicate the case number (as found on page one of this letter) on the petition.
Failure to exercise one of the options above within thirty (30) days of receipt of this letter, as evidenced by an internal
datelime received stamp (not a postmark), will result in this matter being referred to the Attorney General's Office for
collection of the penalty through a civil action. Please be advised that additional penalties may be assessed for violations
that occur after the review period of this assessment.

RE: Notice of Violation & Intent to Assess Civil Penalty
Tracking Number: NOV-2024-LM-0009
Permit No. NC0020354

Dear Ms. Manuel:
This letter is in response to the NCDEQ-DWR letter of February 6, 2024 regarding the violations
that were identified through the review of discharge monitoring reports (DMRs) for the December
2023 monitoring period.
The letter identified three exceedances for this period and were identified as Daily Maximum
Exceeded for Nitrogen, Ammonia Total on December 18, 2023, Daily Maximum Exceeded for
BOD, 5-Day (20 Deg C) on December 29, 2023 and for Monthly Average Exceeded for Nitrogen,
Nitrate Total (as N).
This exceedance can be attributed to the low flow and the inability to perform efficient treatment at
the low flows experienced by the facility. The average flow for this period was 39,000 gallons per
day which is less than 10 percent of permitted flow, which leads to treatment inefficiencies.
Effluent sampling results for the exceedance for December 18 of Ammonia, previous day was
result of < 0.1 mg/L and the day following 0.8 mg/L, with no operational changes or modifications
to plant operations. For the BOD Daily Max exceedance on December 29 the day previous was 9.8
mg/L with the following day 2.0 mg/L, with no operational changes or modifications to plant
operations. With an increase in flow, the plant will be able to more efficiently provide adequate
and efficient treatment.
The monitoring violations we take exception with as Five (5) Fecal Coliform samples were taken
December 4-December 8, 2023 and Five (5) Fecal Coliform samples were taken December 11-
December 15, therefore no monitoring frequency violation occurred. The monitoring violation for
Total Nitrogen calls for a weekly frequency and one was taken during week of December 4-
December 8, 2023, one was taken December 11-December 15, 2023, one was taken week December
17-December 20, 2023, and one was taken week of December 27-December 29, 2023.
Thank you again for continuing to work with the Chatham Park Water Recovery Center. We look
forward to working with NCDEQ-DWR in a very positive and proactive manner as we continue to
improve the facility's environmental stewardship. If upon receipt and review of this information
you have any questions or would like to discuss this matter at greater length, please do not hesitate
to contact me at your earliest convenience at (910) 409-8717 or Tim Smith at (919) 481-3000.

1. The Permittee shall submit discharge monitoring reports electronically using NC DWR's eDMR
application system. See Special Condition A. (13.)
2. Sample locations: I = Influent; E = Effluent
3. The monthly average BOD and Total Suspended Residue concentrations shall not exceed 15% of the
respective influent value (85% removal).
4. Upon decorrunissioning of the Pittsboro WWTP, and upon Division approval of a submitted data review
and monitoring frequency reduction justification for each parameter, begin sampling for BOD5, TSS,
ammonia, total residual chlorine, pH, dissolved oxygen, fecal coliform and conductivity at a monitoring;
frequency of 3/week. The frequency reduction could he for one or more or all parameters.
5. Total Residual Chlorine limit applies if chlorine or chlorine derivative is used for disinfection. The
Division shall consider all effluent TRC values reported below 50 pg/l to be in compliance with this
permit. The Permittee shall continue to record and submit all values reported by a North Carolina
certified laboratory even if these values fall below 50 gig/l.
6. Effluent sampling; for fecal coliform, pH and dissolved oxygen shall be conducted at they manhole
sampling location just prior to combination of flow with the Pittsboro 1N ITP. Upon decommissioning of
the Pittsboro WWTP, affluent sampling for dissolved oxygen shall instead be conducted at the cascade
aerator, just prior to discharge into Robeson Creek and effluent sampling for fecal coliforn and pH shall
be conducted at the remaining Pittsboro WWTP UV disinfection channel.
7. TN = TKN + NO3-N + NO2-N, where TN is Total Nitrogen, TKN is Total Kjeldahl Nitrogen, and NO.-N
and NO2-N are Nitrate and Nitrite Nitrogen, respectively.
8. TN or TP Load is the mass quantity of Total Nitrogen or Phosphorus discharged in a given period of
time. See Condition A. (9.).
9. Limits for TN and TP are specified in Conditions A.(5.) and A.(6.). Compliance with mass limits shall he
determined in accordance with Conditions A.(7.) and A.(8.).
10. The quarterly average for total phosphorus shall be the average of composite samples, ollected weekly
during each calendar quarter (January -March, April -June, July -September, October -December).
11. Effluent hardness sampling should be performed in conjunction with testing for hardness dependent
metals (cadmium, copper, lead, nickel, silver, and zinc).
12. Chronic Toxicity (Ceriodaphnia) P/F at 90%; March, June, September & December. See Condition A.M.).
11. The Effluent Pollutant Scan requirement applies once the facility exceeds a design flow of 1.0 MGD,
establishes a pretreatment plan, or connects to Big Buffalo WWTP. The Permittee shall perform three
effluent pollutant scans during the term of this permit [see condition A. (11.)].
(b.) There shall be no discharge of floating solids or visible foam in other than trace amounts.
