Dear Mr. Warren:
ROY COOPER

MICHAEL S. REGAN
Secretary
LINDA CULPEPPER
Interim Director
Division personnel have reviewed and approved your application for renewal of the subject permit
Accordingly, we are forwarding the attached NPDES permit This permit is issued pursuant to the
requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between
North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007 (or as subsequently
amended).
In response to your comments on the draft permit the Division made the following changes to the permit
• The Division agrees to change the monitoring frequency for BOD, TSS, and fecal coliform to
2/week. Monitoring for ammonia was also modified to 2/week until the new limit takes effect.
Once the new limits are in effect the facility shall monitor on a daily basis and may request a
reduction in monitoring after one year of data is collected.
• The Division agrees to reducing the monitoring frequency for oil & grease to monthly.
• The Division does not agree to change the expiration date to 2023 as we use a basinwide schedule
to renew all the permits in the same basin at the same time. There are two options to complete the
second species toxicity tests, four tests in one year or annual for four years. If the facility selects to
perform the bests annually and doesn't have the results at the time the permit application is
submitted, you can submit the results at a later time.
• The schedule of compliance for copper was eliminated from the permit as requested.
• Upstream sampling for hardness was eliminated from the permit as the discharge is to a zero flow
stream.
This final permit contains the following changes from your previous permit
A reasonable potential analysis (RPA) was performed based on recent effluent data. As a result
of the RPA limits for copper and quarterly monitoring for nickel were added to the permit.
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and
program reports. The final NPDES Electronic Reporting Rule was adopted and became effective
on December 21, 2015. The requirement to begin reporting discharge monitoring data electronically
using the NC DWWs Electronic Discharge Monitoring Report (eDMR) internet application has
been added to your final NPDES permit. [See Special Condition A. (5)]

final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may require
modification or revocation and reissuance of the permit. This permit does not affect the legal requirements
to obtain other permits which may be required by the Division of Water Resources or any other Federal,
State, or Local governmental permits that may be required.

Interference
Inhibition or disruption of the POTW treatment processes; operations; or its sludge process, use, or disposal which
causes or contributes to a violation of any requirement of the Permittee's (or any satellite POTW's if different from the
Permittee) NPDES, collection system, or non -discharge permit or prevents sewage sludge use or disposal in
compliance with specified applicable State and Federal statutes, regulations, or permits. [15A NCAC 02H
.0903(b)(14)]
Pass Through
A discharge which exits the POTW into waters of the State in quantities or concentrations which, alone or with
discharges from other sources, causes a violation, including an increase in the magnitude or duration of a violation, of
the Perrittee's (or any satellite POTW's, if different from the Permittee) NPDES, collection system, or non -discharge
permit. [15A NCAC 02H .0903(b)(23)]
Publicly Owned Treatment Works (POTW)
A treatment works as defined by Section 212 of the CWA, which is owned by a State or local government organization.
This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature. It also includes the collection system, as defined in 15A NCAC 2T
.0402, only if it conveys wastewater to a POTW treatment plant. The term also means the local government
organization, or municipality, as defined in section. 502(4) of the CWA, which has jurisdiction over indirect discharges
to and the discharges from such a treatment works. In this context, the organization may be the owner of the POTW
treatment plant or the owner of the collection system into which an indirect discharger discharges. This second type of
POTW may be referred to as a "satellite POTW organization." [15A NCAC 02H .0903(b)(26)]
"Significant Industrial User" or "SIU"
An Industrial User that discharges wastewater into a publicly owned treatment works and that [I5A NCAC 02H
.0903(b)(33)]:
1. Discharges an average of 25,000 gallons per day or more of process wastewater to the POTW (excluding sanitary,
noncontact cooling and boiler blowdown wastewaters); or
2. Contributes process wastewater which makes up five percent or more of the NPDES or non -discharge permitted
flow limit or organic capacity of the POTW treatment plant. In this context, organic capacity refers to BOD, TSS
and ammonia; or
3. Is subject to categorical standards under 40 CFR Part 403.6 and 40 CFR Parts 405-471; or
4. Is designated as such by the Permittee on the basis that the Industrial User has a reasonable potential for adversely
affecting the POTW s operation or for violating any pretreatment standard or requirement, or the POTW's effluent
limitations and conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options;
5. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraphs 1 or 2 of this definition above has no reasonable potential for adversely affecting the
POTW's operation or for violating any pretreatment standard or requirement, the POTW's effluent limitations and
conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options, and thus is not a
Significant Industrial User (SIU); or
6. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraph 3 of this definition above meets the requirements of 40 CFR Part 403.3(v)(2) and thus is a
non -significant categorical Industrial User.
Section B. Publicly Owned Treatment Works (POTWs)
Version 1110912011.2

r4?DES Permit Standard Conditions
Page 15 of 18
All POTWs must provide adequate notice to the Director of the following [40 CFR 122.42(b)]:

Dear Mr. Warren:
Division personnel have reviewed and approved your application for renewal of the subject
NPDES permit Accordingly, we are forwarding the attached NPDES discharge permit This permit is
issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum
of Agreement between North Carolina and the U.S. Environmental Protection Agency dated October 15,
2007 (or as subsequently amended).
This Final Permit includes the following changes from your previous permit:
• The priority pollutant scan requirement was changed from annual to three times during the
current permit term, consistent with Division guidance for major municipal wastewater
treatment facilities. Please note that this testing requires a low-level analysis method for mercury
(EPA Method 1631E).
• A footnote was added to the limit for TRC such that the Division shall consider all effluent TRC
values reported below 50 µg/L to be in compliance with the permit However, you must continue
to record and submit all values reported by a North Carolina certified laboratory (including field
certified), even if these values fall below 50 µg/L.
• Due to the lack of reasonable potential to cause exceedances of water quality standards, limits
and monitoring requirements for total cyanide and total nickel were eliminated.
• The new dechlorination system was added to the treatment components list on the supplement to
permit cover sheet
• In accordance with Division guidelines following the approval of a Statewide TMDL for mercury, a
special condition regarding a mercury minimization plan (MMP) was added. Guidelines for MMP
development have been placed on the Division website following a stakeholder review process.

The MMP m e de ped within 180 days Additiom fter. . . yew of sample results over
the past five years, limits and monitoring requirements for total mercury were eliminated.
Data analyses indicated that total copper and total zinc exhibited a reasonable potential to cause
exceedances of water quality standards. Monitoring for these parameters will be changed to
quarterly in accordance with Division guidelines for action -level parameters. This monitoring
must be conducted in conjunction with the Quarterly toxicity test
Based on comments received from US EPA, the following additional changes were incorporated into this
Final Permit:
• Effluent limitations for ammonia were revised downward to reflect the limited dilution available
in the receiving stream, Marlowe Creek Per your request, a compliance schedule to provide for
consultant contracting, design, funding, bidding, and construction has also been added. The new
limits will become effective September 1, 2019.
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty
(30) days following receipt of this letter. This request must be in the form of a written petition,
conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of
Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-6714). Unless such
demand is made, this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division
may require modification or revocation and reissuance of the permit This permit does not affect the
legal requirements to obtain other permits which may be required by the Division of Water Quality or
permits required by the Division of Land Resources, the Coastal Area Management Act or any other
Federal or Local governmental permit that may be required. If you have any questions concerning this
permit, please contact Tom Belnick at telephone number [phone].

NW Permit NCO021024
A (2) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 90%. The permittee shall perform at a minimum, quarterly
monitoring using test procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure,"
revised February 1998, or subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure" (revised -February 1998) or subsequent versions. The tests will be performed during the months of March,
June, September, and December. Effluent sampling for this testing shall be performed at the NPDES permitted final
effluent discharge below all treatment processes.
If the test procedure, performed as the first test of any single quarter, results in a failure or ChV below the permit limit,
then multiple -concentration testing shall be performed at a minimum, in each of the two following months, as
described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (revised -February 1998) or
subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the highest
concentration having no detectable impairment of reproduction or survival and the lowest concentration that does
have a detectable impairment of reproduction or survival. The definition of "detectable impairment," collection
methods, exposure regimes, and further statistical methods are specified in the "North Carolina Phase 11 Chronic
Whole Effluent Toxicity Test Procedure" (revised -February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring
Form (MR-1) for the months in which tests were performed, using the parameter code TGP3B for the pass/fail results
and THP313 for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the following address:
Environmental Sciences Section
North Carolina Division of Water Quality
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed aquatic toxicity test forms shall be filed with the Environmental Sciences Section no later than 30 days
after the end of the reporting period for which the report is made. Test data shall be complete, accurate, include all
supporting chemical/physical measurements and all concentration/response data, and be certified by laboratory
supervisor and ORC or approved designate signature. Total residual chlorine of the effluent toxicity sample must be
measured and reported if chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the
permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the facility
name, permit number, pipe number, county, and the month/year of the report with the notation of "No Flow" in the
comment area of the form. The report shall be submitted to the Environmental Sciences Section at the address cited
above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be required
during the following month. Should any test data from this monitoring requirement or tests performed by the North
Carolina Division of Water Quality indicate potential impacts to the receiving stream, this permit may be re -opened
and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism
survival, minimum control organism reproduction, and appropriate environmental controls, shall constitute an invalid
test and will require immediate follow-up testing to be completed no later than the last day of the month following the
month of the initial monitoring.

Permit NCO021024
A (3) EFFLUENT POLLUTANT SCAN
The permittee shall perform a total of three (3) effluent pollutant scans for all parameters listed below. One scan must
be performed in each of the following years: 2013, 2014, and 2015: Analytical methods shall be in accordance with
40 CFR Part 136 and shall be sufficiently sensitive to determine whether parameters are present in concentrations
greater than applicable standards and criteria. Samples should be collected with one quarterly toxicity test each year,
and must represent seasonal variation (i.e., do not sample in the same quarter every year). Unless otherwise
indicated, metals shall be analyzed as "total recoverable."

PART IV
SPECIAL CONDITIONS FOR MUNICIPAL FACILITIES
Section A. Definitions
In addition to the definitions in Part 11 of this permit, the following definitions apply to municipal facilities:
Indirect Discharge or Industrial User
Any non -domestic source that discharges wastewater containing pollutants into a POTW regulated under section
307(b), (c) or (d) of the CWA. [40 CFR 403.3 (i) and 0) and 15A NCAC 02H .0903(b)(l 1)]
Interference
Inhibition or disruption of the POTW treatment processes; operations; or its sludge process, use, or disposal which
causes or contributes to a violation of any requirement of the Permittee's (or any satellite POTW's if different from the
Permittee) NPDES, collection system, or non -discharge permit or prevents sewage sludge use or disposal in
compliance with specified applicable State and Federal statutes, regulations, or permits. [15A NCAC 02H
.0903(b)(14)]
Pass Through
A discharge which exits the POTW into waters of the State in quantities or concentrations which, alone or with
discharges from other sources, causes a violation, including an increase in the magnitude or duration of a violation, of
the Permittee's (or any satellite POTW's, if different from the Permittee) NPDES, collection system or non -discharge
permit. [15A NCAC 02H .0903(b)(23)]
Publicly Owned Treatment Works (POTW)
A treatment works as defined by Section 212 of the CWA, which is owned by a State or local government organization.
This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature. It also includes the collection system, as defined in 15A NCAC 2T
.0402, only if it conveys wastewater to a POTW treatment plant. The term also means the local government
organization, or municipality, as defined in section 502(4) of the CWA, which has jurisdiction over indirect discharges
to and the discharges from such a treatment works. In this context, the organization may be the owner of the POTW
treatment plant or the owner of the collection system into which an indirect discharger discharges. This second type of
POTW may be referred to as a "satellite POTW organization." [15A NCAC 02H .0903(b)(26)]
"Significant Industrial User" or "SIU"
An Industrial User that discharges wastewater into a publicly owned treatment works and that [15A NCAC 02H
.0903(b)(33)1:
I . Discharges an average of 25,000 gallons per day or more of process wastewater to the POTW (excluding sanitary,
noncontact cooling and boiler blowdown wastewaters); or
2. Contributes process wastewater which makes up five percent or more of the NPDES or non -discharge permitted
flow limit or organic capacity of the POTW treatment plant. In this context, organic capacity refers to BOD, TSS
and ammonia; or
3. Is subject to categorical standards under 40 CFR Part 403.6 and 40 CFR Parts 405-471; or
4. Is designated as such by the Permittee on the basis that the Industrial User has a reasonable potential for adversely
affecting the POTW's operation or for violating any pretreatment standard or requirement, or the POTW's effluent
limitations and conditions m its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options;
5. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraphs 1 or 2 of this definition above has no reasonable potential for adversely affecting the
POTW's operation or for violating any pretreatment standard or requirement, the POTW's effluent limitations and
conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options, and thus is not a
Significant industrial User (SIU); or
6. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraph 3 of this definition above meets the requirements of 40 CFR Part 403.3(v)(2) and thus is a
non -significant categorical Industrial User.
Section B. Publicly Owned Treatment Works (POTWs)
Version 11/092011

IPP
""'DE', nit Standard Conditions
Page 15 of 18
All POTWs must provide adequate notice to the Director of the following [40 CFR 122.42(b)]:
1. Any new introduction of pollutants into the POTW from an indirect discharger, regardless of the means of
transport, which would be subject to section 301 or 306 of CWA if it were directly discharging those pollutants;
and
2. Any substantial change in the volume or character of pollutants being introduced by an indirect discharger as
influent to that POTW at the time of issuance of the permit.
3. For purposes of this paragraph, adequate notice shall include information on (I) the quality and quantity of effluent
introduced into the POTW, and (2) any anticipated impact that may result from the change of the quantity or
quality of effluent to be discharged from the POTW.
Section C. Municipal Control of Pollutants from Industrial Users.
1. Effluent limitations are listed in Part I of this permit. Other pollutants attributable to inputs from Industrial Users
discharging to the POTW may be present in the Pemdttee's discharge. At such time as sufficient information
becomes available to establish limitations for such pollutants, this permit may be revised to specify effluent
limitations for any or all of such other pollutants in accordance with best practicable technology or water quality
standards.
2. Prohibited Discharges
a. The Permittee shall develop and enforce their Pretreatment Program to implement the prohibition against the
introduction of pollutants or discharges into the waste treatment system or waste collection system which
cause or contribute to Pass Through or Interference as defined in 15A NCAC 02H .0900 and 40 CFR 403. [40
CFR 403.5(a)(1)]

wastestreams with a closed cup flashpoint of less than 140 degrees Fahrenheit or 60 degrees Centigrade
using the test methods specified in 40 CFR 261.21;
(2) Pollutants which cause corrosive structural damage to the POTW, but in no case discharges with pH lower
than 5.0, unless the works is specifically designed to accommodate such discharges;
(3) Solid or viscous pollutants in amounts which cause obstruction to the flow in the POTW resulting in
Interference;
(4) Any pollutant, including oxygen demanding pollutants (BOD, etc.) released in a Discharge at a flow rate
and/or pollutant concentration which will cause Interference with the POTW;
(5) Heat in amounts which will inhibit biological activity in the POTW resulting in Interference, but in no
case heat in such quantities that the temperature at the POTW Treatment Plant exceeds 40°C (104°F)
unless the Division, upon request of the POTW, approves alternate temperature limits;
(6) Petroleum oil, non -biodegradable cutting oil, or products of mineral oil origin in amounts that will cause
Interference or Pass Through;
(7) Pollutants which result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that
may cause acute worker health and safety problems; or
(8) Any trucked or hauled pollutants, except at discharge points designated by the POTW.
c. The Permittee shall investigate the source of all discharges into the POTW, including slug loads and other
unusual discharges, which have the potential to adversely impact the Pemmittee's Pretreatment Program and/or
the operation of the POTW.
The Permittee shall report such discharges into the POTW to the Director or the appropriate Regional Office.
Any information shall be provided orally within 24 hours from the time the Permittee became aware of the
circumstances. A written submission shall also be provided within 5 days of the time the Permittee becomes
aware of the circumstances. The written submission shall contain a description of the discharge; the
investigation into possible sources; the period of the discharge, including exact dates and times; if the

Re: Notice of Violation — NOV-2022-MV-0097
Permit Number NCO021024 —Roxboro WWTP
Dear Ms. Manuel,
This letter is in response to the NOV sent on June 23, 2022 for the Incident identified as
NOV-2022-MV-0097. As you are aware from the DMR and our email correspondence
with Scott Vinson on May 23, 2022, this monitoring violation occurred as described to
Mr. Vinson as follows:
Our Lab Supervisor Crystal Shotwell informed me that we failed to called an effluent Nh3 sample
on 4/1/2022. Our NPDES permit only required Nh3 samples on our effluent twice/week until new limits
and a daily monitoring requirement took effect on Dec. 1, 2021. We consistently sampled our effluent
for Nh3 daily during the time prior to and after the December 1, 2021 changes. I have spoken to the Lab
Supervisor and believe this to be an isolated incident, in our discussion I asked her to emphasized the
importance of reviewing the established "checklist' daily so that instances like this can be avoided in the
future. She agreed and assured me that she would be having that conversation with our Lab Technician. .
In addition to this issue, your letter is addressed to Thomas S Warren, Jr who has retired
from the City. The City of Roxboro submitted a change in signatory form on July 8, 2021
and that change has not been noted at DWR.
Attached are the emails and Change of Signatory information.
The City of Roxboro strives to provide its citizens with a safe and reliable wastewater
treatment facility and will work with your office in anyway to provide the best customer
service to our citizens. Please feel free to call our office at [phone], if you have
any questions regarding these or any other reports.

Mr. Vinson,
Please accept this email as a follow-up to our phone conversation on 4/3/2022. Today our Lab
Supervisor Crystal Shotwell informed me that we failed to collect an effluent Nh3 sample on

4/1/2022. Our NPDES permit only required Nh3 samples on our effluent twice/week until new limits
and a daily monitoring requirement took effect on Dec. 1, 2021. We consistently sampled our effluent
for Nh3 daily during the time prior to and after the December 1, 2021 changes. I have spoken to the Lab
Supervisor and believe this to be an isolated incident, in our discussion I asked her to emphasized the
importance of reviewing the established "checklist' daily so that instances like this can be avoided in the
future. She agreed and assured me that she would be having that conversation with our Lab
Technician.
We will continue to make every effort to meet the conditions of our NPDES permit and if you need
additional information from me please let me know.
Sincerely,
Derek Clayton

Subject: Compliance Evaluation Inspection
Roxboro WWTP
NPDES Permit No. NCO021024
Person County
On February 15, 2022, Stephanie Goss and Molly Nicholson of the Raleigh Regional Office
(RRO) conducted an inspection at the subject facility. The cooperation of Derek Clayton,
operator in responsible charge (ORC) and Van Rogers (Back-up ORC), was greatly appreciated.
Findings during the inspection were as follows:
1. The current NPDES permit was issued effective November 1, 2018 and will expire on
May 31, 2022. The Division received the City's renewal application on November 22, 2021 and
is in the process of renewing this NPDES permit.
2. The City of Roxboro's Wastewater Treatment Plant is a W W-4 Classification.
3. As reflected in the subject permit and as observed during the inspection, the 5.0 MUD
treatment plant consists of a septic tank unloading facility, two bar screens, two grit
removal devices, two aeration basins, three secondary clarifiers, disinfection system
using sodium hypochlorite with two contact chambers, dechlorination system using
calcium thiosulfate, two aerobic digesters, sludge dewatering facility, three sludge drying
beds, and a standby power generator.
4. The Roxboro W WTP was under construction due to plant upgrades during the time of the
inspection.
5. The plant discharges to Marlowe Creek which is classified as C waters in the Roanoke
River Basin.
6. One aeration basin was in operation during the time of the inspection and appeared to be
operating satisfactorily. Foam was observed on approximately 20% of the surface of the
basin. The second aeration basin was not in use because the facility is able to meet the

permit requirements based on current flows with out incurring additional electrical costs.
Mr. Clayton stated it is used as an equalization basin on an as needed basis.
Mr. Clayton stated that their three clarifiers are approximately twelve feet deep. The
"East" clarifier was not in operation during the time of the inspection because it is not
fully operational and is reliant on the completion of the facilities upgrades. The overflow
weirs on the "Middle" and "West" clarifiers appeared to be level and mostly free of
algae. A sludge judge on the "Middle" and "West" clarifier showed the sludge depth to
be approximately two feet deep in each.
8. The influent and effluent samples are collected by hand using a graduated cylinder to
collect the correct aliquot volume based of flow. The aliquot volume is calculated flow
proportionally using the chart recorder on an hourly basis within a 24-hour period. The
sample is added to a labeled influent and effluent container and kept refrigerated until it
is poured up into sample containers. The refrigerated units were maintained at the proper
temperature, < 6 degrees C.
9. The facility records their flow by using the chart recorder flow meter and was calibrated
on November 22, 2021 by Instrumentation Services, Inc bi-annually.
10. Mr. Clayton stated aerobic digestor # 1 approximately holds 500,000 gallons and was
approximately halfway full during the time of the inspection. Mr. Clayton stated Aerobic
digestor #2 is approximately 1,000,000 gallons and was approximately 9 feet full during
the time of the inspection. Once the sludge is dewatered, it is transferred to the
dewatering facility where the sludge is sent into a centrifuge and a polymer added to
dewater the sludge.
11. Mr. Clayton stated that their sludge is hauled in the fall on a yearly basis by Synagro
where the sludge is land applied. Synagro land applies sludge under permit #
W00021826.
12. Mr. Clayton stated that the facility's chemical feed system for sodium hypochlorite is
used daily and is added into the two contact chambers.
13. Mr. Clayton stated that the facility uses calcium thiosulfate for dechlorination, and it is
added below the chlorine contact basin before the effluent reaches the outfall to Marlowe
Creek.
14. Mr. Clayton stated the onsite diesel generator is tested under load monthly.
15. A review of discharge monitoring report (DMR) data for the period January 2020 through
December 2021 showed all required monitoring was performed.
16. A cursory review of laboratory and DMR data for February 2021 and October 2021
showed consistent reporting of results.

17. A cursory review of calibration logs showed acceptable calibration for the on -site
parameters.
18. Mr. Clayton stated there are two industries in the Town of Roxboro which are the Eaton
Corporation and Spuntech.
19. The effluent discharge appeared free of excess solids. No detrimental impacts to
Marlowe Creek were observed.
20. A daily operator logbook is kept online which details daily operations, problems and
when the plant conducts wasting of the sludge.
21. As required by NCGS 143-215.1C, the City of Roxboro prepares and makes available to
its customers an Annual Performance Report. Mr. Clayton stated he presents his findings
to the City in August of every year and it is distributed via mail to the City's customers
with their water bills.

Dear Mr. Vinson,

This letter is in response to the NOV sent on February 23, 2021 for the Incident identified
as NOV-2021-LV-0103. As you are aware from the DMR and our email correspondence
with Mitch Hayes on December 22, 2020, exceeding this level occurred as a direct result
of a rainfall event that resulted in 1.88 inches of rain between 11/29/20 & 11/30/20. An
Influent daily flow total of 5.59 mgd occurred between the hours of 7am on 11/30/20 and
7am on 12/1/20 and the composite sample for 12/1/20 was collected during these
hours. Activated sludge basin aerators were either all or partially off for 16 of the 24
hours in which the composite sample was collected. The aerators were off and the
solids were allowed to settle in the sludge basin to prevent solids washout due to
excessive flow rates.
The construction activities of our new oxidation ditch have created some temporary flow
restrictions and partial outages of some of our clarifiers. The completion of the
WWTP upgrade as well as addressing identified I & I problem areas in the collection
system should greatly reduce the chances of future violations of our copper limits.
The City of Roxboro strives to provide its citizens with a safe and reliable wastewater
treatment facility and will work with your office in anyway to provide the best customer
service to our citizens. Please feel free to call our office at [phone], if you have
any questions regarding these or any other reports.
Sincerely,
Thomas S. Warren, Jr., Assistant City Manager

Subject: Compliance Evaluation Inspection
Roxboro Wastewater Treatment Plant
NPDES Permit No. NCO021024
Person County
Dear Mr. Warren:
LI r r
On December 23, 2020, Mitch Hayes of the Raleigh Regional Office conducted the subject
inspection. The assistance prodded by Derek Clayton, Operator in Responsible Charge (ORC),
Van Rogers, back-up ORC, and Crystal Shotwell, Laboratory Supervisor, was greatly appreciated.
Below is a summary from review of the permit and the inspection:
The current permit was issued September 25, 2018. became effective November 01, 2018
and expires May 31, 2022. A permit modification vas issued September 22, 2020 to modify
the schedule of compliance for the new ammonia limits becoming effective December 01,
2021.
2. The 5 MGD facility consists of the following units: septic tank unloading facility; two (2)
mechanical bar screens; two (2) mechanical grit chambers; two (2) EQ basins with aeration;
three (3) secondary clarifiers; liquid sodium hypochlorite disinfection system with two (2)
contact chambers; calcium thiosulfate dechlorination system; sludge centrifuge dewatering
facility; two (2) aerobic digesters; three (3) sludge drying beds: and an on -site generator to
provide back-up power.
3. At the time of inspection, both mechanical bar screens and grit chambers were in operation.
One EQ basin was being used due to low inflow. All aerators in the EQ basin being used
was in operation. Two out of three secondary clarifiers were in use. The third was not being
used due to low inflow. Effluent flowing over the weirs appeared clear. The liquid
disinfection system and dechlorination system were operating normally. The sludge
centrifuge dewatering system was not in use. Both digesters were in use at the time of
inspection. One digester measured 2.7 feet deep and the other measured 3.9 feet. There was
no sludge in the sludge drying beds. Effluent appeared clear at the discharge point.

4. Synagro is contracted to haul solids away and apply them to the City's permitted sites under
permit WQ0021826. This permit will expire August 31, 2021.
The Roxboro WWTP laboratory is certified (certification number 191) for fecal colifonn,
BOD, total residual chlorine, conductivity, dissolved oxygen, ammonia nitrogen, pH, total
suspended solids and temperature. Meritech's environmental laboratory analyzes the
remaining pen -nit parameters.
6. Commercial lab results, chain of custody records, and bench sheets were compared with
data submitted on the Discharge Monitoring Report (DMR) for November 2020. No
discrepancies were noted.
Discharge Monitoring Reports for the review period December 2018 through November
2020 were checked for compliance with permit limits and monitoring requirements.
Monitoring violations for dissolved oxygen and temperature were noted for the week
ending January 26, 2019. There were no other violations.

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
The current permit was issued September 25, 2018, became effective November 01, 2018 and expires
May 31, 2022. A permit modification was issued September 22, 2020 to modify the schedule of
compliance for the new ammonia limits becoming effective December 01, 2021.
The 5 MGD facility consists of the following units: septic tank unloading facility; two (2) mechanical bar
screens; two (2) mechanical grit chambers; two (2) EQ basins with aeration; three (3) secondary
clarifiers; liquid sodium hypochlorite disinfection system with two (2) contact chambers; calcium
thiosulfate dechlorination system; sludge centrifuge dewatering facility; two (2) aerobic digesters; three
(3) sludge drying beds; and an on -site generator to provide back-up power.
At the time of inspection, both mechanical bar screens and grit chambers were in operation. One EQ
basin was being used due to low inflow. All aerators in the EQ basin being used was in operation. Two
out of three secondary clarifiers were in use. The third was not being used due to low inflow. Effluent
flowing over the weirs appeared clear. The liquid disinfection system and dechlorination system were
operating normally. The sludge centrifuge dewatering system was not in use. Both digesters were in
use at the time of inspection. One digester measured 2.7 feet deep and the other measured 3.9 feet.
There was no sludge in the sludge drying beds. Effluent appeared clear at the discharge point.
Synagro is contracted to haul solids away and apply them to the City's permitted sites under permit
WQ0021826. This permit will expire August 31, 2021.
The Roxboro WWTP laboratory is certified (certification number 191) for fecal coliform, BOD, total
residual chlorine, conductivity, dissolved oxygen, ammonia nitrogen, pH, total suspended solids and
temperature. Meritech's environmental laboratory analyzes the remaining permit parameters.
Commercial lab results, chain of custody records, and bench sheets were compared with data
submitted on the Discharge Monitoring Report (DMR) for November 2020. No discrepancies were
noted.
Discharge Monitoring Reports for the review period December 2018 through November 2020 were
checked for compliance with permit limits and monitoring requirements. Monitoring violations for
dissolved oxygen and temperature were noted for the week ending January 26, 2019. There were no
other violations.

Subject: Roxboro WWTP (NPDES NC0021024) Influent Flow Monitoring
Mr. Thomas
Mr. Robinson
As you know the Roxboro WWTP is in the process of being upgraded and recently I
informed you that our contractor would be making an Influent Diversion Box tie-in. That
Influent Diversion Box tie-in was completed August 8`h and 9' as noted in an email to
each of you on 8/12/2020. (See the attached drawing) Since that time we've seen a
significant increase in our Influent flow numbers during rain events. I made our Public
Services Director Andrew M. Oakley, PE aware of this and he modeled the situation that
exist and determined that our current flow monitoring is accurate until it reaches 9.25 mg.
After that amount of flow the outlet starts acting like an orifice and stops behaving like a
weir. As a result, he recommended that I inform you that Influent flows above 9 mg are
and will be influenced by the ongoing construction. We will eventually have effluent
flow monitoring as part of the overall WWTP upgrade but it's not available at this time.
This issue will resolve itself once the influent flow and biological treatment is transferred
to the new Oxidation Ditch, however at this point we don't know when that will happen.
If you need additional information please contact me at 336-599-8232 or Mr. Oakley at
336-599-5658.
Sincerely,
Derek Clayton
WWTP Supt.

Mr. Thomas, Mr. Robinson
The Roxboro W WTP Influent Diversion Box Tie -In noted in an email to each of you July 30, 2020 was
completed August 8th & 9th. Influent flow monitoring was interrupted during the tie-in period due to the
conditions described in the original email. Flow monitoring was resumed on Monday August I Oth at 9AM. As
I told Mr. Thomas during a phone call on Monday August I Oth everything went well and we did not experience
any spills during the completion of this work. This email and phone call to Mr. Thomas this morning is an
effort to determine how you'd like me to report the missing flow data from 8/8/20 & 8/9/20 on the upcoming
eDMR. Unless directed otherwise I will mark the August 2020 eDMR as non -compliant for flow
monitoring. I'll also reference the July 30th 2020 and August 12th 2020 emails along with three phone
conversations that I've had with Mr. Thomas concerning the diversion box tie-in and the resulting "anticipated
non-compliance" for flow in the comments section of the edmr. It is always our intention to meet the conditions
of our NPDES permit. However, in this case the non-compliance was unavoidable due to planned construction
work related to the 23 million dollar upgrade at the Roxboro W WTP .
If you have any questions or need additional information please let me know.

Good afternoon Vanessa, 7E'
I hope you are doing well.
In an effort to maintain essential city services and to protect the health, safety and welfare of the citizens and employees
of the City of Roxboro the City will begin a split work group program. This program called the COVID-19 Emergency
Work Group Guidelines (attached) will go into effect Monday April 6, 2020. As you will see in the attached document the
separation will continue until May 1, 2020, the duration may be shortened or lengthened as determined by the City
Manager. It is my intention to continue to meet the requirements of our NPDES permit during this time however I will
notify you in the event that this does not occur due to limited staffing. There are two attachments to this email, the first
one includes the guidelines from the City Manager and the second is a memo to our staff designating the individual
groups.
If you need additional information please email or call.

Operators in the same group can practice social distancing at shift change however when
operators from different groups change shifts they are to leave as soon as the relief
operator comes in with little to no contact. Any communication that needs to be made
between the two operator groups at shift change should be done on the phone.
Let me know if you have questions.
Thanks for all you do,

thru Friday you will continue to work Monday thru Friday )
7 The work groups will not intermingle with other work groups Employees in Work
Group A can assist employees in another department in Work Group A But carp
not help any employees in -
8 Employees in Work Group A car be called in to assist -and
employees in - =a' - be called in to assist employees in Work
Group A under any circumstances

9. When an employee's work group is off, no employee from that work group can
return to the work place or any city property or city work site.
10. The use of electronic devices will be the recommended method forr maintaining
continuity of service and to communicate between the work groups.
11. Association with employees in another work group is discouraged while the

Dear Mr. Bolich
As required by our NPDES permit (NC0021024) I called and spoke with Zachary Thomas within 24 hours
of becoming aware that we didn't have a sample result for effluent Dissolved Oxygen and Temperature for
sample date 1/24/19. 1 followed up the phone call with the attached email from the same day I/31/19 and
noted the violation in the comments section of the January 2019 edmr.
As stated in the email to Mr. Thomas, dated 1/31/2019,1 immediately revised our operator daily log to
include a verification requirement to be completed by our night shift operator who comes in daily at 5pm.
In the event there is no data recorded on the log for any given day the night shift operator will get the
effluent DO & temperature within his first hour of the shift and notify me, the Chief Operator or Lab
Supervisor. If the data is present on the daily log, the nightshift operator will simply initial that he did look
and verify that it had been done. A memo to our staff was sent out with these requirements.
I will also be sharing your violation notification with our W WTP staff in an effort to bring awareness of
both the individual and staff responsibilities we must meet to ensure compliance with all the conditions of
our NPDES permit. We take these conditions very seriously therefore I can assure you of three things;
1. We will make every effort to maintain compliance with the conditions of our permit.
2. We will always report our mistakes when they occur.
3. We will learn from our mistakes by implementing changes as necessary to reduce/eliminate their
occurrence.
If you have any questions please feel flee to contact me at 336-599-8232.
Sincerely,
Derek Clayton

Subject: Compliance Evaluation Inspection
Roxboro Wastewater Treatment Plant (WWTP)
NPDES Permit No. NCO021024
Person County
Dear Mr. Ayscue:
On January 31, 2019, Cheng Zhang of the Raleigh Regional Office (RRO) conducted a
compliance evaluation inspection of the subject facility. The assistance provided by Mr. Derek
Clayton, the operator in responsible charge (ORC), and Ms. Crystal Shotwell, the Laboratory
Supervisor, was greatly appreciated as it facilitated the inspection process. The inspection report
is attached. The following observations were made:
Roxboro WWTP is permitted to discharge at a rate of 5.0 MGD and consists of: septic tank
unloading facility, dual bar screens and grit removal system, two aeration basins, three
secondary clarifiers, disinfection system (sodium hypochlorite) with two contact chambers,
calcium thiosulfate dechlorination system, two aerobic digesters, sludge dewatering facility,
and three sludge drying beds. The facility discharges into Marlowe Creek, which is classified
C waters in the Roanoke Basin.
1. The current permit became effective on October 1, 2018.
2. At the time of inspection, all listed treatment units were in operable conditions. One of
the two aeration basins was online due to low flow. Lower effluent ammonia limits will
become effective on September 1, 2019. Accordingly, construction (a new oxidation
ditch and two aerobic digesters) was underway as specified in the Authorization to
j

Construct issued by the 1-...,;ion. When the new oxidation ditch is ... service, the two
existing aeration basins will be converted into equalization basins.
3. Wasted activated sludge is treated and thickened in the two aerobic digesters. Final
sludge is either hauled away for land application or further dewatered with the sludge
centrifuge. Sludge cake was stored at the covered storage area.
4. The ORC maintains a daily logbook. Lab results, chain -of -custody forms, and DMRs
were complete and current, kept in good order and ready for review. October 2018 DMR
data were compared to lab bench sheets; no data transcription errors were noted. Influent
and effluent flow meters were calibrated annually.
5. The right of way to the outfall was well maintained. No visible impacts were noted
immediately downstream the effluent pipe.
6. Field lab parameter (Certificate No. 191) calibration and analysis records were reviewed
during the inspection.
If you have any questions regarding the attached reports or any of the findings, please contact
Cheng Zhang at: [phone] (or email: cheng zhany(dincdenngov).

tck Bolich, L.G.

Hey Zach,
As a follow up to our conversation earlier this morning I'm emailing you to let you know that we failed to get the effluent
DO and temperature as required in our NPDES permit No. NC0021024 on 1/24/19. In an effort to keep this from
happening again I've revised our operator daily log to include a verification requirement to be completed by our night
shift operator who comes in daily at 5pm. In the event there is no data recorded on the log for any given day the night
shift operator will get the effluent DO & temperature within his first hour of the shift and notify me, the Chief Operator or
Lab Supervisor. If the data is present on the daily log, the nightshift operator will simply initial that he did look and verify
that it had been done. A memo to our staff was sent out earlier today with these new requirements.
Let me know if you have any questions,
Sincerely,
Derek Clayton

Source of the Upset/Spill/Bypass (Location or Treatment Unit).
At 11:47 am on 9/17/18 during a period that our facility experienced 20mg plus flow rates for 3.5 hours
continuously, a bar screen shear pin failure resulted in water backing up and out of the manhole
"pick" holes approx. 100 feet upstream from the bar screen inside the POTW. The estimated volume
was calculated based on the NCDENR website guidance. Diameter of pick hole 1", number of pick
holes 16... height of water from pick hole 1" result from guidance chart for each hole... 0.94 gpm x
time in minutes 10 x 16 holes = 150 gallons. Once the screen was cleared manually the bypass
stopped.
Cause or Reason for the Upset/Spill/Bypass:
Severe Natural Conditions: Heavy rain from Hurricane Florence on 9/17/18 resulted in one of our
influent bar screens breaking a shear pin at a 20mg plus flow rate. The bypass occurred during the
ten minutes it took to clear the bar screen manually. Repeated attempts were made on the 17" to
replace the shear pin but each time the new pin broke as well. Operators manually cleaned the
screen until flow rates dropped enough to have all the flow go through the other channel.

North Carolina Dep.,;ment of Environment and Natural Resources
Describe the Repairs Made or Actions Taken:
On Tuesday the 18`h the influent channel directly in front of the bar screen was cleared of grit, gravel
and rock which had accumulated during and after the initial shear pin break. There was damage to
the rake "teeth" on all four rakes so they were replaced with new ones. Bar Screen was repaired,
tested and is now available for service if the primary screen fails or if conditions (flow rates) require
both channels in operation.

Action Taken or Proposed to be Taken to Prevent Occurrences.
We take storms like Hurricane Florence very seriously and started preparing for it on 9/10/18. On
9/12118 at 08301 had a phone conversation with NCDENR contact Zach Thomas and reviewed what
we had been doing to prepare for the coming storm. One of the items discussed and documented
was to inspect and tighten both screening and grit removal equipment. We will continue to do our
equipment preventive maintenance and additional prep when storms like Florence are forecasted.
See attached storm prep document
Additional Comments About the Event:
As a follow up to "Did the Spill/Bypass reach the surface waters?" The area around the manhole
where this occurred is graveled and most of this water was absorbed by them. Also the storm drain
in the area was protected due to the ongoing WWTP upgrade (construction) If any of the estimated
150 gallons reached the surface waters it was very small percentage of the total estimate. Our focus
at that time was to clear the screen and stop the overflow not stand and watch it happen.

Subject: DWQ phone call, concerning Hurricane Florence storm prep.
Date: 9/12/18
Storm Prep. What we've done!
1. Reviewed and initiated severe weather plan.
2. Topped off 600 kw generator with fuel and load tested last week.
3. Lowering rain water level in 3 mg south aeration basin that's not in use. This
basin can be and has been used as an equalization basin in extreme conditions.
4. Removed materials that were in stored in areas previously flooded during
hurricane and tropical storms events.
5. Checked sandbags and re -bagged ones that needed it that may be used to protect
our pump station closest to the creek. This pump station was flooded during
Hurricane Fran.
6. Meeting scheduled for 1 pm today with City Public Services Director, Assistant
City Manager, General Contractor Haren Construction and Project Engineers to
discuss plant upgrade progress and storm preparation.
7. Contractor is doing there own housekeeping and shoring up silt fences in the
excavation areas. After the phone call ... Haren had KBS build a berm that
was graded south to north on the west side of the excavation for the oxidation
ditch. They also installed a check dam on the north side of the berm which
hopefully will direct water and mud from the hillside excavation away from
the east clarifier located directly across by having it empty off the hill in and
around the digester / generator area. Haren also has placed plastic on the
banks of the digester 2 excavation site.
8. We've notified our septic haulers that if weather conditions at the plant deteriorate,
the city will not be accepting septic waste and they should call or have alternate
plans for disposal.
Storm Prep. What's left to do!
1. Continue to monitor the storm track.
2. Ensure staff can make it in and pick up if necessary.
3. Final Prep .... tie down sludge judges, life rings, adjust chain tension on screening /
grit removal equipment
Talked to Zack Thomas with DWQ at 0830 on 9/12/18 and went over this information
with him. He said he / DWQ realizes that we and other facilities may flood due to the
amount of rainfall associated with the storm and they wanted us to know that our staff
safety was the first concern. He also said they would be checking back after the storm to
find out how we faired. I assured him that we would be documenting the event if we
experience flooding conditions, power outages etc ... He also left these numbers for
reporting spills and other problems during the event. 1-800-858-0368, 919-733-3300

Good afternoon Vanessa,
Our Pretreatment Coordinator has been working on the Pretreatment Headworks Analysis and in the process discovered
that I didn't include Influent ammonia on the March 2016 edmr. Influent ammonia is not in our permit but we do test it
weekly for background information and I have those results. Also, it appears that I entered Influent copper and zinc
results from March 8, 2016 on both the influent and effluent page. I will make the necessary corrections, include them in
a revised edmr and resubmit the revision. Please let me know if this action is sufficient and if there is anything else you
need from me.

On Thursday, November 7, 2017, Vanessa Manuel and Jeremiah Dow of the Raleigh Regional
Office conducted a compliance evaluation inspection of the treatment facilities located at the
Roxboro Wastewater Treatment Plant (WWTP). The purpose of this inspection was to ensure
compliance with the subject NPDES permit. During the inspection, the presence and
cooperation of Derek Clayton, Operator in Responsible Charge (ORC), Van Martin Rogers,
Backup ORC, and Crystal Shotwell, Pretreatment Coordinator/Lab Supervisor were helpful and
appreciated.
The Roxboro WWTP is located at 902 Cavel-Chub Lake Road in Roxboro, North Carolina. The
facility is a grade IV activated sludge wastewater treatment plant that treats domestic and
industrial wastewater and is authorized to discharge the treated wastewater through outfall 001
into Marlowe Creek, a waterbody classified as C waters within the Roanoke River Basin.
This NPDES compliance evaluation inspection consisted of the following:
• Review of the NPDES permit;
• Review of the owner/facility information;
• Review of June 2015 — August 2017 monitoring data;
• Review of June 2015 — August 2017 compliance history;
• On -site inspection of the laboratory;
• On -site inspection of the wastewater treatment units; and
• On -site inspection of the discharge outfall.

Thomas S. Warren, NC002102 .
November 20, 2017
Findings during the pre -inspection file review were as follows:
1. Through NPDES permit NC0021024, the City is authorized to discharge treated wastewater
from Roxboro WWTP to receiving waters designated as Marlowe Creek, classified C waters
in the Roanoke River Basin. At the time of the inspection, the administratively continued
NPDES permit was issued effective July 1, 2013, and expired May 31, 2017. The Division
received the City's permit renewal application on October 17, 2016, and is in the process of
renewing this NPDES permit.
2. Roxboro WWTP, classified WW-4 (Grade IV Biological Water Pollution Control System),
provides treatment and discharge through the outfall pipe to Marlowe Creek. As listed in the
subject permit, the treatment components include a septic tank unloading facility, two bar
screens [mechanical], two grit removal devices [mechanical], two aeration basins, three
secondary clarifiers, a disinfection system (sodium hypochlorite) with two contact chambers,
a calcium thiosulfate dechlorination system, two aerobic digesters, and three sludge drying
beds. Since the issuance of the current permit, the following treatment unit was installed and
placed into service during December 2016: Sludge dewatering facility using centrifuge
technology.
3. Beginning December 21, 2016, EPA's NPDES Electronic Reporting Rule requires pernrittees
to submit their discharge monitoring reports (DMRs) electronically, instead of on paper. The
first DMR the Division received electronically from the City was for January 2015. To learn
more about the eDMR system, please visit the Division's eDMR website at
https://deg.nc.gov/about/divisions/water-resources/edmr.
4. For the review period June 2015 — August 2016, no valid limit or monitoring violations were
detected: No penalty assessments have been issued since July 2004, and the last Notice of
Violation was issued in August 2016, for failure to monitor per the requirements of the Long -
Term Monitoring Plan (LTMP). For the 2-year period ending August 2017, Roxboro WWTP
has been compliant with its Whole Effluent Toxicity limit and monitoring requirements.
Findings during the inspection were as follows:
5. The operator's log and supporting analytical documentation were consistent and up to date.
6. The Roxboro WWTP laboratory is certified for and self -reports monitoring data for the
following parameters (certification number 191): Fecal Coliform, BOD, Total Residual
Chlorine, Conductivity, Dissolved Oxygen, Ammonia Nitrogen, pH, Total Suspended Solids,
and Temperature. The City uses Meritech's environmental laboratory (certification number
165) to analyze the remaining parameters required by the permit. An inspection of the meter
calibration logs, standards, incubator temperatures (fecal and BOD) showed the laboratory to
be compliant with record -keeping requirements. In-house thermometers are calibrated
annually against the NIST certified thermometer. Most of the in-house thermometers were
calibrated during January 2017. Other thermometers were calibrated in July and August
2017. The NIST certified thermometer is sent off every 5 years for calibration. The NIST
certified thermometer was last calibrated on September 4, 2014.
7. The inspectors compared the December 2016 and July 2017 DMR data against Roxboro
WWTP lab's bench data and Meritech's analytical results. The only discrepancy noted was
the calculation of Total Nitrogen on July 5, 2017. The ORC included the analytical value for
Ammonia Nitrogen (NH3N) in the calculation of Total Nitrogen. Total Nitrogen (TN) is
calculated as follows: TN = TKN + NO3-N + NO2-N, where TKN is Total Kjeidahl

Thomas S. Warren, NC00:
November 20, 2017
Nitrogen, and NO3-N and NO2-N are Nitrate and Nitrite Nitrogen, respectively. The ORC
stated he will amend the July 2017 eDMR with the corrected TN value and submit it to the
Division.
8. The inspectors noted the following observations of the treatment components:
a) Primary Treatment. The mechanical bar screens and grit removal chambers were in
operation and did not appear to have any issues that would affect proper operation. The
screenings collected after the influent flow passes through these processes are retained in
a dumpster before being hauled to the landfill. The area around these units was clean and
well maintained.
Q
10.
11.
b) Secondary Treatment. One of the 2 aeration basins was in operation. All fixed aerators
were observed operational; no apparent issues of concern were observed. The second
aeration basin was not in use due to low flow volume through the plant. Duckweed was
observed throughout the full length of this basin. The clarifier units were all operational.
The weirs appeared level, and little to no pin floc or other floating solids were observed
within the units. The sludge depth in the middle and East Clarifiers were observed at 1.2
feet and less than 1 foot, respectively. The volume depth in each of these units is
approximately 12-feet.
c) Disinfection. The facility disinfects the treated wastewater prior to discharge using a
liquid chlorine feed (sodium hypochlorite) followed by a liquid dechlorination feed
(calcium thiosulfate). No issues of concern were observed with the disinfection system.
d) Sludge Treatment. Waste activated sludge is removed from the clarifiers and pumped to
the aerobic digesters. The ORC stated the solids are retained in the digesters as long as
possible to meet the 503 requirements. Digested sludge/biosolids are pumped to the new
dewatering facility for further dewatering via centrifuge and then stored on a covered
concrete pad. The sludge hauler, Synagro, is contracted annually to haul the solids away
and apply it to the City's permitted sites under permit WQ0021826. No issues of concern
were observed with the sludge treatment system.
Flow measurement at the treatment plant is performed at the influent. The flow meter is
calibrated at least annually and was last calibrated on May 23, 2017. The facility also
measures flow using a chart recorder. The inspectors observed the flow measurement on the
chart recorder, which is located inside the administrative building, at 1.42 MGD, and the
flow measurement from the ultrasonic flow meter located at the influent station at 1.65
MGD. No issues of concern were observed with the flow measurement devices.
The inspectors observed the effluent discharge to Marlowe Creek via the outfall pipe to be
clear with no observable solids or foam. No detrimental impacts to Marlowe Creek from the
effluent discharge were observed.
The ORC stated the backup generator holds 1700 gallons of fuel, which will allow the
generator to run 36 hours at load. The generator has an auto -transfer switch. The facility
also has the ability to manually transfer power to the generator in case the auto -transfer
switch fails. At least once a month, the operators test the generator under load.

The overall condition of the subject facility was compliant with the NPDES permit requirements
as observed on the day of the inspection. If you have questions or comments about the
inspection, this report or the requirements to take corrective action (if applicable), please contact

Hi Derek —
My apologies for not being able to receive your call this morning. I was in the field as my outgoing voice message
indicated.
If the facility's permit requires daily monitoring, then as long as the required parameter is sampled 5 out of every 7 days
per week (Sunday through the following Saturday), then the facility will have met the permit's measurement frequency
requirement.
Thanks for providing notice to this office of the issue surrounding the Oct. 9`h fecal collection/setup. I will place a copy
of this email correspondence in our files.

Hello Vanessa,
I called you this morning but your voicemail indicated that you were in the field today so I spoke with Jason Robinson
and let him know that we don't have a fecal coliform result for Monday 10/9/2017. I explained to Jason that the sample
was collected and setup however the Lab Tech had to leave for a doctors appointment on Tuesday and we forgot to take
the samples out of the incubator and do the counts. I also told Jason that we plan on collecting a sample on
this Saturday the 14th and the Lab Supervisor will be reading them on Sunday. So we will have five consecutive days
with fecal coliform results it just won't be Monday - Friday, it will be Tuesday - Saturday instead. If this constitutes a
violation of the permit please accept my phone conversation with Jason and this email as the required reporting but if the
extra sample collected and analyzed on Saturday meets the compliance criteria please let me know so I won't mark next
months edmr as non -compliant.
If you have questions please let me know.
Sincerely,
Derek Clayton

The NPDES permit for the City of Roxboro's W WTP expires on May 31, 2017. As required we are hereby
submitting the application for permit renewal of NPDES NC0021024.
The plant is a 5.0 MGD extended aeration plant, that discharges to Marlowes Creek in the Roanoke River
Basin. Synagro Central land applies the biosolid residuals generated from the operation of the W WTP per
our land application permit W00021826.
The following changes were made to the Roxboro W WTP treatment process during the 2013-2017 permit
cycle.
• Added a sludge dewatering facility utilizing centrifuge technology.
The following is a list of major equipment replacements/rehab either completed or budgeted for completion
during this permit cycle.
• Both grit collectors have been replaced with new ones.
• Middle (original) clarifier has been overhauled, including rebuilt drive, extensive concrete floor work and new coatings.
• West (original) clarifier mechanicals have been replaced with new drive, catwalk, metal structure.
• Diffusers replaced in both sides of aerobic digester.
• East (1980's) clarifier mechanicals will be replaced in the 201612017 budget year.
An Authorization to Construct (No. 021024A03) has been issued for modifications to the City of Roxboro
W WTP. These modifications became necessary due to lower NH3 limits included in the 2013/2017
NPDES permit and become effective 9/1/2019.
If any other information is needed for the permit renewal, please contact Derek Clayton at 336-599-8232.

SUPOLEMENTAL APPLICATION INFORMATION
PART E. TOXICITY TESTING DATA
POTWs meeting one or more of the following criteria must provide the results of whole effluent toxicity tests for acute or chronic toxicity for each of the
facility's discharge points: 1) POTWs with a design flow rate greater than or equal to 1.0 mgd; 2) POTWs with a pretreatment program (or those that are
required to have one under 40 CFR Part 403); or 3) POTWs required by the permitting authority to submit data for these parameters.
• At a minimum, these results must include quarterly testing for a 12-month period within the past 1 year using multiple species (minimum of two
species), or the results from four tests performed at least annually in the four and one-half years prior to the application, provided the results
show no appreciable toxicity, and testing for acute and/or chronic toxicity, depending on the range of receiving water dilution. Do not include
information on combined sewer overflows in this section. All information reported must be based on data collected through analysis conducted
using 40 CFR Part 136 methods. In addition, this data must comply with QAIQC requirements of 40 CFR Part 136 and other appropriate QAIQC
requirements for standard methods for analytes not addressed by 40 CFR Part 136.
• In addition, submit the results of any other whole effluent toxicity tests from the past four and one-half years. If a whole effluent toxicity test
conducted during the past four and one-half years revealed toxicity, provide any information on the cause of the toxicity or any results of a
toxicity reduction evaluation, if one was conducted.
• If you have already submitted any of the information requested in Part E, you need not submit it again. Rather, provide the information
requested in question EA for previously submitted information. If EPA methods were not used, report the masons for using alternate methods.
If test summaries are available that contain all of the information requested below, they may be submitted in place of Part E.
If no biomoniloring data is required, do not complete Pail E. Refer to the Application Overview for directions on which other sections of the form to
complete.

Inflow / Infiltration Rates Attachment B
Period Covered ---January 2014 - August 2016
Base Flow into Roxboro POTW Excluding Infiltration equals
The lowest average monthly flow from the period covered pIUS the highest
monthly flow from the period covered
divided by two = X
where,
a = the lowest average monthly flow was 1.42 mgd from August 2015
b = the highest average monthly flow was 3.29 mgd from December 2015
X = a+b
2
X = 1.42+3.29
2
X = 4.71
2
X = 2.36 mgd base flow excluding inflow/infiltration
Record difference for each daily flow in the covered period over 2.36
Example 1/l/l6 Daily flow = 3.11— 2.36 = 0.75 mgd inflow/infiltration
Add difference for each day/month and divide by # of days/month = amount of
inflow/infiltration into POTW/ month
Repeat for each month in the covered period
Add the amount of inflow/infiltration entering POTW each month and divide by 12
Avg/day inflow/infiltration for 2014 = 0.185 mgd
Avg/day inflow/infiltration for 2015 = 0.253 mgd
Avg/day inflow/infiltration for 2016 = 0.219 mgd
Average/day inflow/infiltration last 32 months (Jan. 2014 — August 2016) = 0.219

Roxboro W WTP Sludge Management Plan
Revised 5/11/16
Waste activated sludge is removed from the treatment system from the secondary
clarifiers. It is pumped to our aerobic digesters. We have 2 digesters. Each will hold
228,000 gallons. The sludge is first pumped into our primary digester where it is aerated
with compressed air. The air is distributed trough fine bubble diffusers. The air is turned
off and the solids are allowed to settle so that the decant liquid is drawn off and returned
to the head of the aeration basin.
When the primary digester is filled with solids, those solids are transferred to the
secondary digester. They are aerated with compressed air and excess water is decanted if
possible.
Solids are retained in the digesters as long as possible to insure that we meet 503
requirements for volatile solids reduction.
Digested Sludge/Biosolids are then pumped to our dewatering facility for further
dewatering via centrifuge and stored on a covered concrete pad where our contractor
(Synagro) will later pick them up for land application on permitted fields in Person
County NC. Centrate from the centrifuge operation is returned to head of the existing
activated sludge basin.
As a back-up to the centrifuge
Sludge solids are pumped from the secondary digester to our sludge lagoons. We have
(1.5) two acre lagoons of which sludge can be pumped. Sludge is normally pumped in a
lagoon from 6 months to 1 year. After filling a lagoon it is valved off, the water in the
sludge is filtered into a drain system and returned the head of the activated sludge basin.
The drying of the sludge is also aided by sun evaporation.
When the sludge is dry enough to be removed from the lagoons, we have a contract with
Synagro to remove it. They use front-end loaders and dump trunks to haul and apply it to
the City of Roxboro's permitted sites. This is operated under permit WQ0021826.

Person County
Dear Mr. Oakley:
Mitch Hayes of the Raleigh Regional Office conducted the subject inspection on November 24, 2015.
The assistance of Derek Clayton, Van Rogers and Crystal Shotwell with this inspection was appreciated.
Please find attached to this letter the Basin Wide Information Management System (BIMS) check list.
Below is a list of findings developed from the inspection:
1. The permit became effective July 1, 2013 and will expire May 31, 2017.
2. BIMS lists Derek Clayton as the Operator in Responsible Charge (ORC) and Van Rogers as the back-
up ORC.
3. The wastewater treatment facility consists of the following units: septic tank unloading facility,
two bar screens, one with % inch opening and one with 1 inch opening; one-half inch auger; 2 —
influent flow channels; chain and bucket grit collector; Parshall flume with a transducer flow
meter; 2 each 3 MG aeration basins; 3 each — 0.345 MG secondary clarifier; chlorine contact
chamber with 2 chambers; calcium thiosulfate dechlorination system; 2 each —0.228 MG aerobic
digesters; 2 sludge drying beds; a covered dry sludge storage pad; 600 KW on -site generator. A
sludge dewatering building which consists of an in -line sludge grinder, a 700 dry pound/hour
centrifuge, a polymer feed system, a dried -sludge screw conveyer system.
4. At the time of inspection, one influent channel was being used due to low inflow. The chain and
bucket grit collector was operating normally. One aeration basin was in operation due to low
inflow. All aerators were operational. The aerated influent appeared chocolate brown in color
with minimum foaming. All three secondary clarifiers were operational. Sludge blankets are kept
between 1 and 2 feet. Effluent flowing off the weirs appeared clear with no pin floc. Effluent
flowing into Marlowe Creek appeared clear with no foaming. The sludge dewatering facility was
not in operation at the time of inspection. There was a small amount of Class B biosolids in the

5. The facility is field certified for pH, temperature, dissolved oxygen, total residual chlorine, and
specific conductance. The Roxboro WWTP Laboratory analyzes BOD, TSS, NH3-N, and fecal
coliform. Merritech Labs analyzes oil and grease, all long term monitoring, pretreatment, toxicity
and all other parameters. All calibration logbooks are maintained, all pH buffers were within
expiration date. Temperatures are checked against an NIST thermometer with any correction
factors noted. The BOD incubator temperature was 20.0 degrees C. The fecal incubator
temperature was 44.5 degrees C.
6. Discharge Monitoring Reports (DMRs) forthe period October 2014through September 2015 were
reviewed for compliance with permit limit and monitoring requirements. BIMS is listing
monitoring violations forflow during February through September2015. A review of the database
revealed that this coincides with the beginning of electronic DMR reporting. Apparently BIMS is
monitoring for effluent flow when influent flow is being reporting. BIMS will be changed to
monitor for influent flow. Please continue to report influent flow. There are no violations for the
review period.
Commercial lab results, chain of custody records, and bench sheets were compared with data
submitted on the DMR for September 2015. No discrepancies were noted.
I would like to thank Derek Clayton, Van Rogers, and Crystal Shotwell for their time and assistance
with this inspection. If you have any questions concerning this letter or the inspection, please contact

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
The wastewater treatment facility consists of the following units: septic tank unloading facility; two bar
screens, one with '/z inch opening and one with 1 inch opening; one-half inch auger; 2 — influent flow
channels; chain and bucket grit collector; Parshall flume with a transducer flow meter; 2 each 3 MG
aeration basins; 3 each — 0.345 MG secondary clarifier; chlorine contact chamber with 2 chambers;
calcium thiosulfate dechlorination system; 2 each — 0.228 MG aerobic digesters; 2 sludge drying beds;
a covered dry sludge storage pad; 600 KW on -site generator. A sludge dewatering building which
consists of an in -line sludge grinder, a 700 dry pound/hour centrifuge, a polymer feed system, a
dried -sludge screw conveyer system.
At the time of inspection, one influent channel was being used due to low inflow. The chain and bucket
grit collector was operating normally. One aeration basin was in operation due to low inflow. All
aerators were operational. The aerated influent appeared chocolate brown in color with minimum
foaming. All three secondary clarifiers were operational. Sludge blankets are kept between 1 and 2 feet.
Effluent flowing off the weirs appeared clear with no pin floc. Effluent flowing into Marlowe Creek
appeared clear with no foaming. The sludge dewatering facility was not in operation at the time of
inspection. There was a small amount of Class B biosolids in the covered dry sludge storage pad.
There was no sludge in the drying beds.
The facility is field certified for pH, temperature, dissolved oxygen, total residual chlorine, and specific
conductance. The Roxboro WWTP Laboratory analyzes BOD, TSS, NH3-N, and fecal coliform.
Merritech Labs analyzes oil and grease, all long term monitoring, pretreatment, toxicity and all other
parameters. All calibration logbooks are maintained, all pH buffers were within expiration date.
Temperatures are checked against an NIST thermometer with any correction factors noted. The BOD
incubator temperature was 20.0 degrees C. The fecal incubator temperature was 44.5 degrees C.
Discharge Monitoring Reports (DMRs) for the period October 2014 through September 2015 were
reviewed for compliance with permit limit and monitoring requirements. BIMS is listing monitoring
violations for flow during February through September 2015. A review of the database revealed that this
coincides with the beginning of electronic DMR reporting. Apparently BIMS is monitoring for effluent
flow when influent flow is being reporting. BIMS will be changed to monitor for influent flow. There are
no violations listed for the review period.
Commercial lab results, chain of custody records, and bench sheets were compared with data

Whole Effluent samples (split samples collected using the facility's sampler) were collected from
Roxboro WvrTP on June 2 and June 4, 2015 by Cheng Zhang of Division of Water Resource (DWR),
Raleigh Regional Office. These samples were for use in a chronic Ceriodaphnia dubia pass -fail toxicity
test, which was performed by the staff at DWR Aquatic Toxicity Branch. This test passed for the
toxicity inspection. Toxicity test information follows.
Test Type 3-Brood Ceriodaphnia dubia chronic pass fail
Test Concentration 906/0

Autumn,
Thanks, I've talked to our Lab Supervisor and she is going to implement your suggestion (item
3) in an effort to keep this from happening again. I'll take care of items 1 & 2 at the
appropriate time.

Derek,
I checked and RRO approves of the following:
1)Please attached the bench sheet that shows that a sample was taken on both 1/8 and 1/9 with
the DMR.
2) In the comment box indicate what happened, and that you are reporting the results for 1/8
and 1/9, without the ability to determine which result is actually the 1/9 result due to the
mislabeling.
3) An idea would be to institute a daily check of the sample bottle label by 2nd person or
calendar check by the person taking the sample, to prevent occurrence in the future.
If you have questions, please feel free to contact me.
Sincerely,
Autumn

Autumn,
Yes, labeled (dated) incorrectly one of the two should have been 1/9.
For samples analyzed in our lab the sample bottle is labeled and all the information is
placed directly on the benchsheet. The benchsheet was dated 1/9 correctly, but I don't know
for sure which result goes with 1/8 and which goes on 1/9.

Derek,
By saved do you mean labeled incorrectly as having been taken on 1/8, when it was actually
taken on 1/9?
Also, do you have an ORC chain of custody sheet or bench sheet that is notes the sample was
taken on 1/9?

Good morning Autumn,
I saw your email the other day and thanks for the kind thoughts on my recovery. Yesterday I
transferred from my "boot" to an ankle brace and shoe, it was a huge step in the right
direction (I hope) but I've still got some improving to do before I can stop using my cane
and walk with any speed. I'm thankful for the progress so far and other than that, time will
tell how good its going to get.
I do have an issue that I need some direction on, our lab is running NH3 today and found out
that we had two samples saved and labeled for 1/8/15. The problem is one of the two is for
1/9/15, it was just saved with the incorrect date. There are no compliance issues with
either sample so my question for you is, how should I report this? I can average the two
samples labeled 1/8/15 and report that number for the 1/8/15 date and be non -compliant for
1/9/15 or do you have an alternative that is acceptable?
Also, if I do need to average the results of the samples labeled 1/8/15 and be non -compliant
for 1/9/15 (missing data) can you accept this as my notification of violation?
Thanks for your help on this and if you have any questions please let me know.
Sincerely,
Derek Clayton

Dear Mr. Oakley:
Compliance Evaluation Inspection
City of Roxboro WWTP
Permit No: NCO021024
Person County
On December 3, 2014, Mack Wiggins of the Raleigh Regional Office conducted a Compliance
Evaluation Inspection of the City of Roxboro's Wastewater Treatment Plant. The assistance of Mr.
Derek Clayton and Ms. Crystal Shotwell was very helpful and appreciated during the inspection
process.
1. The Plant was configured as per the permit and is classified as a Class W W-4 facility.
Mr. Derek Clayton is the ORC and has a Grade IV Certification, Mr. Van Rodgers is the
backup operator and has a Grade IV Certification and Ms. Crytal Shotwell is the
Laboratory Supervisor.
2. A review of the DMRs revealed consistent reporting of results as required by the permit.
3. All logs and documentation were consistent and up to date.
4. Bench data was found to be consistent with DMR data.
I. Wastewater Treatment Plant site inspection:
1. Wastewater enters the plant through a mechanical grit & screening removal system
before moving forward to dual aeration chambers. The mechanical grit and screening
system was clean and free of excessive debris at the time of the inspection. Screenings
and grit material are collected in a dumpster and carried to the landfill once per week.
2. After screening and grit removal, wastewater goes forward to two aeration basins in
parallel. Each basin is design to hold 3 million gallons. Only one basin was in use at the
time of the inspection. Surface aerator was operational and the basin was free of dead
spots at the time of the inspection. The dissolved oxygen level in the aeration basin was
1.33 mg/I at the time of the inspection.

3. After aeration wastewater moves forward to the secondary clarifiers. The facility utilizes
three clarifiers. One clarifier was currently being overhauled at the time of the
inspection. One of the two in use at the time of the inspection had been overhauled in
2013. The weirs of the clarifiers in use were observed to be free of excessive floating
sludge. The sludge blankets of both clarifiers was 2 feet at the time of the inspection.
All three clarifiers have a side wall depth of 15 feet.
4. Return activated sludge lines and waste activated sludge lines were open and free of
clogging at the time of the inspection.
5. After the secondary clarifier wastewater moves forward to disinfection. The facility
utilizes sodium hypochlorite for disinfection and calcium thiosulfate for dechlorination.
6. Analyticals for toxicity and metals are performed by Meritech Inc. The facility analyses
for all other parameters including field parameters. The facility is field certified for field
parameters pH, Temperature, Dissolved Oxygen and Residual Chlorine.
7. Sludge is wasted to two aerobic digesters. Each digester holds 228 thousand gallons.
Both digesters had adequate capacity with available tankage at the time of the
inspection.
8. The facility originally had three 2 acre sludge lagoons to hold the Class B sludge. One of
the lagoons now houses a new centrifuge for sludge dewatering. A roof has been
installed over the remaining half of that lagoon for sludge storage. Only ''/. of the covered
area for sludge storage held class B sludge at the time of the site visit. The remaining
two lagoons are utilized as back-ups to the centrifuge. The back-up lagoons did not
contain any sludge at the time of the site visit. All decant from the back-up lagoons and
the centrifuge when in use is piped back to the influent to the aeration basins.
9. Sludge is collected and land applied once per year by Synagro.
10. Effluent was clear with very little foam at the time of the inspection.
Thank you all for your assistance during this inspection. Please refer to the enclosed inspection
report for additional observations, comments and recommendations. If you or your staff have any
questions, please call Mack Wiggins at (919)7914200.

Person County
Dear Mr.Oakley:
The North Carolina Division of Water Quality conducted an inspection of the Roxboro Water
Treatment Facility on 12/08/2014. This inspection was conducted to verify that the facility is
operating in compliance with the conditions and limitations specified in NPDES Permit No.
NC0002861.The assistance of Arnold Oakley to complete the inspection was greatly appreciated.
A summary of the findings and comments noted during this inspection is provided in the attached
inspection report entitled "Compliance Inspection Report".
During the inspection, a new Ion Exchange Water Treatment Unit was observed to be operational and
discharging backwash wastewater to the wastewater settling basin (wastewater treatment system).
Wastewater from Ion Exchange Water Treatment is not currently covered by your NPDES discharge
permit. The current NPDES discharge permit authorizes the discharge from Conventional Water
Treatment plant filter backwash water and filter wastewater from the plant decanting lagoon system.
The wastewater characteristics for Ion Exchange Treatment discharge are different from conventional
backwash and lagoon decanting wastewater. Please review Section E (I. Change in Discharge and 2.
Planned Changes) on the 11/09/2011 Standard Conditions pages of the permit.
Accordingly, please respond in writing to this letter within 30 des of receipt Your response should
address the items listed below:
1) It is the understanding of the Raleigh Region that the Town of Roxboro intends to send this
wastewater to the Town's W WTP by conecting to a sewer line. Please explain how this will
occur and when you anticipate this will be accomplished.
2) If this is not the case, please explain how you propose to eliminate the Ion Exchange
Treatment discharge wastewater (e.g. pump and haul). [Note: If this option is chosen a pump
an haul waste approval will be required. Please contact the Raleigh Regional Office for the
appropriate application if you are planning to pursue this option.]

3) If the Town does not plan to eliminate the Ion Exchange Treatment discharge wastewater then
you will need to modify your NPDES permit. This modification is to accomodate and reflect,
as appropriate, the addition of this new wasteslream.
Thank you for your attention to this matter. If you have any questions concerning this report, please
contact Autumn Romanski at 919-791-4255or myself at (919) 7 1 4252.

Good morning Autumn,
I'm sending you this message to inform you that our west final clarifier is down and will be
down for repair for some time. We are working with Russell Underwood again, his company
CRUCO made the repairs to our middle final clarifier in 2012/2013. Currently were still in
the inspection/recommendation phase of the repair however I don't anticipate any problems
with effluent quality while this unit is down as we still have two final clarifiers still in
service.
Let me know if you have questions,

Derek,
The City of Roxboro's wastewater treatment plant has the design capacity that is equal to 5.0 MGD and as such
is required to have continues operation, 24 hours, seven days per week, with each shift staffed by at least one
certified wastewater operator. However, you explained due to severe conditions (an injury, a retirement, an
employee death and vacancies) that the Town is unable to currently staff each shift with one certified
wastewater operator. You have also explained that the Chief Operator (both he and yourself) are on call
24hrs/day to respond to any problems that may arise at the plant.
This office agrees with your concern that 7 day 12hr/day every week (being at the plant with the trainees) it is a
lot to ask of existing certified operators.
Therefore, due to the staffing issues and safety concerns that are coincident to the daily shift work you
described, this office agrees to temporarily relax the requirement for 24 hours, seven days per week, with
each shift staffed by at least one certified wastewater operator.
It is my understanding that Rural Water is planning to provide training and you hope to have current employees
take their Grade I Operator course in March. Accordingly, please provide this office monthly updates that
indicates the progress the City of Roxboro is making with respect to hiring certified operator(s). Also, please
clearly communicate (e.g. May or June 2014) when you anticipate being able to return to conditions that allows
you maintain at least one certified wastewater operation with each shift, as required.
If you have any questions please call me at [phone].

Hey Danny,
In August of 2012 the City of Roxboro hired two operator trainees and they have worked with
our Chief Operator since that time. They took the Grade I Wastewater Certification exam in
December and unfortunately they both failed. In the last two weeks we found out that one of
our certified operators was leaving to work at the new plant opening soon near Cary NC. On
top of that we had another certified operator find out he has cancer and is currently in Duke
hospital. This operator is at retirement age and I don't expect he will be back based on
what were hearing from family. I myself am still recovering from a broken ankle and even
though I'm available for paperwork I'm not much help out in the plant. This has left us with
only two full time certified operators and two uncertified trainees. The city has contacted
the rural water association about holding an exam eligible school in January or early Feb.
2014 that we would send not only our two current uncertified trainees for additional training
prior to the March exam but we plan on hiring two additonal operators that will most likely
be uncertified to attend this school and take the March exam as well.
We realize that we are required to have a certified operator on shift at all times, but we
would like to request from you or someone that you feel could grant it, a waiver of this rule
through March 2014. At your earliest convenience please let me know if this is waiver is
possible. We (the city) feel we have been proactive in our efforts to maintain adequate
staffing of certified operators however we are currently experiencing an unprecedented turn
of events at our plant. In any event we will continue to do our very best to meet all the
requirements of our permits and state law that applies to our WWTP operation.
If you have questions or need any additional information concerning this matter please call.

Dear Mr. Oakley:
Mitch Hayes of the Raleigh Regional Office conducted the subjected inspection on October 30, 2013. The
assistance of Derek Clayton and the staff of the WWTP with the inspection were appreciated. Below is a list of
findings and recommendations developed from the inspection:
Basinwide Information Management Systems (BIMS) list Derek Clayton as the grade 4 wastewater
(WW4) Operator in Responsible Charge (ORC) and Tommy Satterfield as the back-up ORC (bORC),
WW-4. Currently Van Rogers, WW-4, is serving as the bORC and Tommy Satterfield, WW-4, is on
stand-by. Other bORC's listed for the WWTP are Richard Strand, WW4, and Willie Lee Wrenn, WW-4.
2. The subject permit was reissued May 22, 2013 and became effective July 01, 2013. The following
changes were made to the permit: the priority pollutant scan requirement was changed from annual to
three times during the current permit term; monitoring requirements for total cyanide and total nickel
were eliminated; monitoring requirements for total mercury were eliminated however, a mercury
minimization plan (MMP) must be developed within 180 days of permit effective date.
3. The Division of Water Resources will implement an electronic discharge monitoring report program.
This program requires all NPDES-permitted facilities report monthly monitoring report data
electronically through the Division's eDMR (Electronic Discharge Monitoring Report) program. All
existing permitted facilities and any new permitted facilities/dischargers will be required to comply with
the permit requirement no later than 90 days after the permit becomes effective. For more information
on eDMRs, registering for eDMR submittal, and obtaining an eDMR user account, please visit DWR's
webpage: hftp://portal.ncdenr.org/web/wq/admin/bog/ipu/edmr.
4. The wastewater treatment facility consists of the following units: septic tank unloading facility; two bar
screen; one-half inch auger; 2 — influent flow channels; chain and bucket grit collector; Parshall flume
with a transducer flow meter; 2 each 3 MG aeration basins; 3 — 0.345 MG each secondary clarifier;
chlorine contact chamber with 2 chambers, calcium thiosulfate dechlorination system; 2 — 0.228 MG
each aerobic digesters; 2 sludge drying beds, 600 KW on -site generator. A sludge dewatering building
which will consist of an in -line sludge grinder, a 700 dry pound/hour centrifuge, a polymer feed system,
a dried -sludge screw conveyer system, and a covered dry sludge storage pad was being constructed.
The construction was approximately 70% complete.

5. At the time of inspection one influent channel was being used due to low inflow. The chain and bucket
grit collector was operating normally. One aeration basin was in use, the other basin is used as an
equalization basin when needed. The aerated influent appeared chocolate brown with minimum foam.
Aerators are operated by a timer switch. Mr. Clayton stated that the aerators will be turned off during
the installation of a centrifuge pump. All three secondary clarifiers were in use. Sludge judge readings
were two feet in the west and the middle clarifiers and one foot in the east clarifier. Effluent flowing off
the weirs appeared clear with no pin flock. Effluent flowing into Marlowe Creek appeared clear with no
foam or solids. The aerated primary digester was three-quarters full and the secondary aerated digester
was one -quarter full. When the primary digester is full, solids are transferred to the secondary digester
and aerated with compressed air until most of the water can be drawn off. The solids are then pumped
to the sludge drying beds. Synagro is contracted to haul the dried sludge and land apply to the City of
Roxboro permitted sites. This operation is covered under permit WO0021826. There was no sludge in
the drying beds. As of the date of this inspection, no sludge has been land applied from this facility.
6. The facility is field certified for pH, temperature, and dissolved oxygen total residual chlorine and
specific conductance. Pace Laboratories is used for metal analyzes. Merritech labs is used for toxicity.
The Roxboro WWTP Laboratory analyses all other parameters. All buffers are within expiration date.
Temperatures on all equipment were checked against an NIST thermometer on April 2013. The effluent
flow meter was last calibrated December 11, 2012. All calibration logs are maintained. The well
organized records and the assistance of Ms Crystal Shotwell and Jason Wilson hastened the laboratory
inspection.
Discharge Monitoring Reports (DMR's) for the period October 2012 through September 2013 were
reviewed for compliance with permit limit and monitoring requirements. No discrepancies or violations
were noted.
8. Commercial lab results, chain of custody records, and bench sheets were compared with data
submitted on the DMR for August 2013. No discrepancies were noted.
I would like to thank Derek Clayton and the staff of the Roxboro WWTP for their time and assistance with
this inspection. If you have any questions about this letter or the inspection, please contact Mitch Hayes at

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
The subject permit was reissued May 22, 2013 and became effective July 01, 2013. The following changes
were made to the permit: the priority pollutant scan requirement was changed from annual to three times
during the current permit term; monitoring requirements for total cyanide and total nickel were eliminated;
monitoring requirements for total mercury were eliminated however, a mercury minimization plan (MMP)
must be developed within 180 days of permit effective date.
The wastewater treatment facility consists of the following units: septic tank unloading facility; two bar
screen; one-half inch auger; 2 — influent flow channels; chain and bucket grit collector; Parshall flume with a
transducer flow meter; 2 each 3 MG aeration basins; 3 — 0.345 MG each secondary clarifier; chlorine
contact chamber with 2 chambers; calcium thiosulfate dechlorination system; 2 — 0.228 MG each aerobic
digesters; 2 sludge drying beds; 600 KW on -site generator. The construction of the sludge dewatering
building which will consist of an in -line sludge grinder, a 700 dry pound/hour centrifuge, a polymer feed
system, a dried -sludge screw conveyer system, and a covered dry sludge storage pad was approximately
70% complete.
At the time of inspection one influent channel was being used due to low inflow. The chain and bucket grit
collector was operating normally. One aeration basin was in use, the other basin is used as an equalization
basin when needed. The aerated influent appeared chocolate brown with minimum foam. Aerators are
operated by a timer switch. Mr. Clayton stated that the aerators will be turned off during the installation of a
centrifuge pump. All three secondary clarifiers were in use. Sludge judge readings were two feet in the west
and the middle clarifiers and one foot in the east clarifier. Effluent flowing off the weirs appeared clear with
no pin flock. Effluent flowing into Marlowe Creek appeared clear with no foam or solids. The aerated primary
digester was three-quarters full and the secondary aerated digester was one -quarter full. When the primary
digester is full, solids are transferred to the secondary digester and aerated with compressed air until most
of the water can be drawn off. The solids are then pumped to the sludge drying beds. Synagro is contracted
to haul the dried sludge and land apply to the City of Roxboro permitted sites. This operation is covered
under permit WQ0021826. There was no sludge in the drying beds. There has been no land applied sludge
to the date of this inspection.
The facility is field certified for pH, temperature, and dissolved oxygen total residual chlorine and specific
conductance. Pace Laboratories is used for metal analyzes. Merritech labs is used for toxicity. The
Roxboro WWTP Laboratory analyses all other parameters. All buffers are within expiration date.
