NPDES Permit NC0023965 for CFPUA's James A. Loughlin (Northside) Wastewater Treatment Plant
expires on November 30, 2023 with the renewal application due to the Division of Water Resources no
later than June 3, 2023. To fulfill this deadline and provide time for processing prior to expiration, the
necessary NPDES permit renewal application is attached. It consists of the following components:
NPDES Form 2A Basic Application
2. NPDES Form 2A Supplemental Application, Parts D, E, and F and supplemental notes
3. Chemical Addendum disclosure form as required by Session Law 2018-5, Senate Bill 99, Section
13.1(r) and supplemental attachment of additional pollutants

Exceptional Compliance Data Summary for maintaining monitoring reduction
Monitoring reductions at this facility for BOD, NH3 as N, TSS, and Enterococci began in November 2014
for 16 MGD permitted flow due to meeting NCDENR's criteria for exceptional compliance, which
includes:
This facility has had no civil penalty assessments for permit limit violations for each of the four
target parameters during the past three years. Data are from March 1, 2020 through February
28, 2023.
Neither CFPUA nor CFPUA employees have been convicted of criminal violations of the Clean
Water Act within the past five years.

• This facility is not currently under an SOC for effluent limit noncompliance for the four target
parameters.
• As demonstrated in the attached data summary, the three-year arithmetic means of effluent
data for BOD, TSS, and NH3 as N are less than 50 percent of the monthly average permit limit for
each of the parameters. The three-year geometric mean of effluent data for Enterococci is also
less than fifty percent of the monthly geometric mean permit limit.
• No daily sampling results during the three-year period are over 200 percent of the monthly
average limit for BOD or TSS. Only one sampling result during the three-year period is over 200
percent of the monthly average limit for NH3 as N.
• No daily sampling results during the three-year period are over 200 percent of the monthly or
weekly average limit for Enterococci.
• There have been no weekly average limit violations or monthly average limit violations for BOD,
TSS, NH3 as N, or Enterococci during the past three years.
• The transfer of North Carolina DMR data to the ECHO database has resulted in some data
reporting errors. There have been no violations of the Clean Water Act at the Northside WWTP
in the past three years for limits or monitoring frequency requirements. Violations listed in
ECHO are in error. The ECHO website notes that North Carolina is working with the EPA to
resolve this issue.
• A reduction in effluent monitoring for this facility should not impair DWQ's assessment of
downstream uses. The consistency of our data over the three-year period supports that a
reduction in the frequency of monitoring should provide sufficient data to evaluate the water
quality of our discharge.
The Northside WWTP has maintained its exceptional compliance record and requests that the
monitoring reduction stay in force through this next permitting cycle.
Please let me know if there are any questions or whether this application is deemed complete. If all
considerations are otherwise in order, we await receipt of a draft permit and compliance schedule for
review.
Sincerely,

CFPUA staff had samples from the operational effluent analyzed by identified certified methods for pollutants that are certified by the NC State Lab. This includes pollutants that
are not included in the routine NPDES permit monitoring and priority pollutant list. These "detected" pollutants are summarized in the table attached. This summary includes
results for HAS and other pollutants at this process control location, which CFPUA believes is a good estimate of the value that would be present in the effluent discharge.

James A. Loughlin (Northside) WWTP 2023 NPDES Renewal Application
Narrative Description
The Cape Fear Public Utility Authority (CFPUA) has approximately 80 remote wastewater
pump stations that collect and distribute wastewater to James A. Loughlin Wastewater
Treatment Plant (WWTP), also known as the Northside WWTP. Flow from those pump
stations enters the WWTP site and discharges at the screening/grit removal facility.
From the screening and grit removal facility the preliminary treatment effluent (PTE)
flows by gravity to two primary clarifiers. The primary clarifiers will remove the sludge
and primary scum and pump them to the anerobic digester facility. The primary effluent
(PE) will flow by gravity to the aeration basin. The primary clarifiers do have a bypass
line for event management.
Primary effluent (PE) combines with return activated sludge (RAS) from the RAS pump
stations. Both PE and RAS flows through the aeration basin for biological treatment. The
effluent wastewater from the aeration basin is mixed liquor (ML).
The mixed liquor is distributed proportionally to the four secondary clarifiers. RAS is
pumped back to the aeration basin by RAS pump stations 1 and 2. The waste activated
sludge is wasted out of the RAS pump station discharge header and is pumped to the
gravity belt thickening facility. Once the waste activated sludge has been processed it is
pumped to the anaerobic digesters.
Secondary clarifier effluent (SCE) flows by gravity to the tertiary filters. The filtered
effluent will flow by gravity to the UV disinfection facility. All backwash reclaim water
from the tertiary filters is returned to the head of the aeration basins.
The plant effluent is disinfected in four UV channels and the flow is metered with a
parshall flume. The UV effluent flows to the two effluent pump stations. The effluent
pump stations will pump the treated plant effluent to the Cape Fear River through
NPDES outfalls 001 and 002. Either of the two pump stations have adequate capacity to
pump the design average plant effluent flow of 16 MGD. At the hydraulic peak flow of
40 MGD, both stations are required.

Cape Fear Public Utility Authority (CFPUA)
James A. Loughlin (Northside) WWTP 2023 NPDES Renewal Application
CFPUA Residuals Management
Introduction
The Cape Fear Public Utility Authority (CFPUA) was created by the City of Wilmington, NC and
New Hanover County, NC on July 1, 2008, to consolidate provision of water and wastewater
services within their combined services areas. Its core principles are stewardship, sustainability,
service, safety, and excellence. Its mission is to provide quality water and wastewater services to
our community. The Authority strives to provide the safest and highest quality water and
wastewater services with heightened consideration of the unique environment within which it
operates and the efficiency and effectiveness of service as it impacts its customers whose user
fees are its sole funding source.
CFPUA operates and maintains two wastewater treatment plants (WWTP) and two water
treatment plants (WTP) —the James A. Loughlin WWTP (Northside Wastewater Treatment Plant —
NSWWTP), the M'Kean Maffitt WWTP (Southside Wastewater Treatment Plant — SSWWTP), the
Sweeney Water Treatment Plant (SWTP), and the Richardson Water Treatment Plant (RWTP).
Residuals sources from these facilities include NSWWTP dewatered residuals, SSWWTP
dewatered residuals, and SWTP dewatered alum residuals. Periodic maintenance and cleaning of
the NSWWTP digestion system, SSWWTP digestion system, and the SWTP tankage generate
additional residuals.
Residuals produced by these facilities are processed and managed in accordance with NCDENR
Permit WQ0001271 governing land application of Class B wastewater residuals and Permit
WQ0011869 governing distribution of Class A wastewater residuals. As applicable, and in
conformance with all regulatory programs/authorizations, CFPUA also supports a process of
receiving non-CFPUA residuals for processing and disposal under its residuals permits, including
any modifications necessary to enable and support this practice.
The NSWWTP is a 16 million gallon per day (MGD) advanced treatment level facility located at
2311 N. 23d Street in Wilmington, NC. It was originally placed into service in 1970 as an 8 MGD
secondary treatment facility, and many improvements have been incorporated in the intervening
period. Construction was completed in 2009 on an $80,000,000 plant expansion/upgrade project
begun in 2005. Liquid treatment processes installed at this facility include screening, grit removal,
primary sedimentation, activated sludge secondary biological treatment, filtration, and ultraviolet
(UV) disinfection. Solids treatment processes include gravity belt thickening, anaerobic digestion,
and belt filter press dewatering. The liquid leaving the plant (effluent) is of extremely high quality
as set forth in the facility's National Pollutant Discharge Elimination System (NPDES) permit limits
and is currently returned to the environment by discharge to the Cape Fear River.
Solids/residuals produced within the plant's processes are stabilized to North Carolina Class B
land application standards but are currently landfilled at a municipal landfill. Additionally, they
can be processed to North Carolina Class A Product/Distribution standards using alkaline

stabilization. Residuals generated within CFPUA's Sweeney Water Treatment Plant are pumped to
the NSWWTP for processing.
The SSWWTP is a 12 MGD secondary treatment level facility located at 3436 River Road in
Wilmington, NC. It was originally placed into service in 1972 as a 6 MGD facility serving the city of
Wilmington. It was later expanded to 12 MGD to serve New Hanover County and the Town of
Wrightsville Beach, and other improvements were also incorporated throughout the intervening
period. Improvements in the capacity and level of treatment processes currently installed at this
facility include screening, grit removal, primary sedimentation, trickling filtration and activated
sludge secondary biological treatment, secondary clarification, and ultraviolet (UV) disinfection.
Solids treatment processes include gravity belt thickening, anaerobic digestion, and belt filter
press dewatering. The liquid leaving the plant (effluent) is of high quality as set forth in the
facility's National Pollutant Discharge Elimination System (NPDES) permit limits and is currently
returned to the environment by discharge to the Cape Fear River. Solids/residuals produced
within the plant's processes are stabilized to North Carolina Class B land application standards but
are currently landfilled at a municipal landfill.
2022 Performance
NSWWTP
During 2022, the NSWWTP processed approximately 38,874,627 gallons of anaerobically digested
residuals with an average total solids concentration of 1.3% (2,127 dry tons), yielding 16,496 cubic
yards (13,854 wet tons) of dewatered residuals at an average total solids concentration of 15.4%.
SWTP
During 2022, the SWTP conveyed to the NSWWTP by pipeline approximately 17,513,889 gallons
of alum residuals at an average total solids concentration of 1.4% (1,025 dry tons), yielding 6,038
cubic yards (5,093 wet tons) of dewatered residuals at an average total solids concentration of
20.0%.
SSWWTP
During 2022, the SSWWTP processed approximately 16,185,002 gallons of anaerobically digested
residuals with an average total solids concentration of 1.3% (856 dry tons), yielding 6,637 cubic
yards (5,575 wet tons) of dewatered residuals at an average total solids concentration of 15.3%.
CFPUA Residuals Permits
CFPUA currently possesses two residuals permits — Class A Residuals Permit WQ0011869 and Class
B Permit WQ0001271.
The Class A permit allows the conversion of a maximum of 8,270 dry tons per year of residuals
from the NSWWTP, SSWWTP, and SWTP into a maximum of 16,540 dry tons DT per year of Class
A EQ residuals for distribution using an alkaline stabilization process/system located at the
SSWWTP. No residuals were processed through this system during 2022. This permit expires on
October 31, 2025.

The Class B permit allows land application of a maximum of 8,270 dry tons per year of residuals
cake from the NSWWTP, SSWWTP, and SWTP onto permitted sites. No residuals were land
applied under this permit during 2022. During 2022, approximately 29,171 cubic yards were
disposed of by landfilling. For the land application permits, a total inventory of 2,964.97 acres on
107 sites is currently identified/permitted. The permit expires on March 31, 2026.
CFPUA Residuals Management Contracting
In 2019, CFPUA transitioned from having a contractor manage the entire residuals program,
including dewatering, to a CFPUA managed residuals program. CFPUA managed residuals
program consists of dewatering, contracted hauling of dewatered residuals, and landfill disposal.
Landfill disposal is expected to continue due to the presence of PFAS in the dewatered residuals.

Cape Fear Public Utility Authority (CFPUA)
James A. Loughlin (Northside) WWTP 2023 NPDES Renewal Application
Mercury Minimization Report of Activities
The Cape Fear Public Utility Authority (CFPUA) drafted a Mercury Minimization Plan (MMP)
during the previous permit cycle. However, due to the ongoing discussions between publicly
owned treatment works (POTWs), the North Carolina Department of Environmental Quality (NC
DEQ), and the Environmental Protection Agency (EPA) regarding the minimization plans and the
dental amalgam rule, many of the activities were placed on hold pending the resolution of the
requirements. Following receiving the James A. Loughlin wastewater treatment plant (WWTP),
also known as Northside WWTP, permit that went into effect in 2018, staff updated the MMP
and began moving forward with the requirements.
Cape Fear Public Utility Authority ensured the EPA Method 1631E (low level) mercury sampling
occurred at the influent and effluent operational and NPDES monitoring locations. All
significant industrial users (SIUs) transitioned to require sampling their effluent discharges for
mercury. During this reporting period, all monitoring has been changed to EPA Method 1631E
to ensure accurate analysis at the low levels required by this pollutant of concern. During
annual inspections of the SIUs, a review of raw materials is a part of this process. The data
collected for the SIUs and the WWTPs over this reporting period has been compiled to create a
baseline to measure improvements as further mercury education and minimization activities
occur. As a result, the most recent headworks analysis and allocation tables do not reflect an
overallocation of mercury.
The CFPUA Laboratory evaluated its procedures, chemicals, and equipment and identified
mercury -containing items. These items were either replaced or proper disposal techniques
implemented. All mercury thermometers were replaced with non -mercury thermometers. The
previously used chloride method conducted in the lab used mercury -containing reagents and
was changed to a method that does not use mercury. The chemical oxygen demand (COD)
analysis is the only test that still requires mercury. The non -mercury method is not approved
for compliance samples. Changes have been made to this method to consolidate testing where
possible to minimize quality control requirements, generating less mercury waste. A hazardous
waste disposal company picks up this waste to ensure it is properly disposed of and not
released into the environment.
We now have a section of our website on the Environmental Protection page with mercury
minimization/educational information available to the public so they can make wise choices on
products and disposal of such products. Further education has occurred with local dental
offices via the New Hanover County (NHC) American Dental Association and our coordination
with this group. In our MMP, staff outlined a task for more outreach and surveys of other non -
domestic users. In 2022, surveys were sent to over 2,600 non -domestic users. Responses were
recorded from labs, schools, medical facilities, and other entities that may contain mercury.

Moving forward, the Fats, Oils, and Grease biannual bill stuffers will also include language
about mercury to educate customers on proper disposal methods, hazards, and sources.
Regarding the Dental Amalgam Rule, CFPUA took a leadership role as a member of the North
Carolina Pretreatment Consortium (NCPC), working with both the NCPC and the NC DEQto
develop a "Dental Amalgam Rule" plan to be used by POTWs within North Carolina. The goal
was to have consistency with all POTWs. Locally, CFPUA met with the NHC American Dental
Association Chairman to allow the dentists to provide input. These efforts created three options
authorized by NC DEQ to be used by North Carolina POTWs. CFPUA chose "Option One" from
the "North Carolina Model Enforcement Response Plan," which is: Implementing the 3 Rs
(receive, review, retain) and added the following discretionary statement to the ERP:
"Enforcement actions taken in response to the requirements of 40 CFR Part 441 will be
taken/decided on a case -by -case basis." In the event of mercury issues at the POTW, NC DWR
will require increased oversight and enforcement.
CFPUA obtained a list of New Hanover County Dentists from the North Carolina Dental Society.
The dentists were entered into an Excel spreadsheet for report tracking purposes. As "One Time
Compliance Reports" (OTCR) are received, they are reviewed and retained. There are 169
dentists within the service area. CFPUA has contacted the NHC Dental Association and has
worked through this organization to educate the local dental providers on the amalgam
separator requirements and the OTRC. To date, twelve OTCRs have been received. Additionally,
CFPUA Environmental Management and Sustainability Department met with internal
Engineering Plan Review staff and the New Hanover County Plumbing Department to discuss
the requirements of the "Dental Amalgam Rule." Both require all new dental facilities to install
ISO 11143 compliant amalgam separators. Seven dental offices meeting the requirements to
require an amalgam separator have opened businesses in new or upfitted buildings within our
service area during the reporting period, and all are complying.
