Attention: Mr. Michael

Re:NPDES Permit#NC0024911 Renewal Application
Enclosed herewith is the subject NPDES permit renewal application for the Metropolitan
Sewerage District of Buncombe County, North Carolina (MSD) - French Broad River
Water Reclamation Facility. MSD owns/operates the subject reclamation facility located
at 2225 Riverside Drive,Asheville, NC 28804. The facility is a 40 MGD plant that
incorporates a secondary treatment, fixed film design. The current permit expires on
December 31, 2022 and MSD does hereby request renewal with this application
submittal. Enclosed with the application is all requested supportive documentation.
MSD's Consulting Engineer provided recommendations for optimizing ammonia removal
through operational refinements of the existing facility, as well as capital improvements
to be constructed over the next several years. MSD has incorporated these recommended
projects into its Capital Improvement Plan (CIP) in a phased approach to maintain
treatment while accomplishing the needed plant improvements. MSD has an "ammonia
schedule of compliance" in the current NPDES Permit which stipulates ammonia
compliance by October 1, 2030. As discussed below, many issues have arisen that were
totally unpredictable and unprecedented when the original "ammonia schedule of
compliance" was established.
In November 2020, a major fire in an MSD storage facility destroyed new equipment for
the High-Rate Primary Treatment (HRPT) project which is a part of the "ammonia
schedule of compliance" (see attached reports). The equipment had to be re-procured
and added approximately nine (9) months to the construction schedule. In addition to the
fire, the COVID pandemic significantly delayed construction progress by interrupting
equipment and material supply chains and impacting staffing levels at the job site.
Outbreaks among the Contractor and its subs resulted in multi-week shutdowns as
personnel complied with local and state-mandated health requirements.
The HRPT is not fully commissioned preventing MSD from gathering critical performance
data necessary for design decision making for upgrade to a new biological treatment
process. This new biological process is the key component in removal of ammonia to
achieve NPDES permit compliance. The biological treatment replacement project will
require a significant capital cost in the range of eighty ($80) million dollars, MSD's largest
capital project to date. The cost could even increase based on the supply chain issues

which continue to plague the acquisition of parts and equipment for existing and new
construction projects. Expenditures of this magnitude require copious amounts of data
and deliberate planning to make sound engineering decisions.A reduced level of
performance data could result ineffective and inefficient biological operations for MSD,
and an unjust use of rate payer monies.
Based on events that have occurred during the current permit cycle,the lack of HRPT
operational data to date, and the anticipated capital costs of a new biological treatment
process, MSD is requesting an extension of the "ammonia schedule of compliance" to
October 1, 2035.As I am sure you understand,maintaining protection of the water
quality in the French Broad is MSD's primary objective. MSD has continued to do that by
undertaking first the most critical system improvements,through careful management
and maintenance of MSD existing facilities, and through a carefully planned CIP program.
However, superior maintenance,thoughtful management and excellent planning can only
improve timing of a project to a certain extent.Without the requested extension MSD
could be forced into a noncompliance situation. MSD is keenly aware of the role the
NPDES permitting program plays in this effort. MSD would request the opportunity to
review and discuss a preliminary draft renewal permit before DWR finalizes the draft for
public notice. Please notify me when DWR gets to the preliminary draft stage to arrange a
1 review and a meeting. Certainly,we are available to answer any questions you or your
staff may have concerning our renewal application.
Additionally, MSD is requesting reduced monitoring frequency based on exceptional
performance as outlined in October 22, 2012 guidance.The reduction from 5 days per
week to two (2) days per week, for Total Suspended Solids (TSS) and fecal coliform. The
current TSS permit limits is 30mg/l. Calculations from January 1, 2019 to April 29, 2022
average TSS is 13.6 mg/l. During the same time,the fecal coliform geometric mean is 2.1
colonies/100m1.
If there is any additional information needed to proceed with processing this renewal
request, please do not hesitate to contact Roger Edwards at 828-225-8224.

At the beginning of 2021, MSD had twenty (20) Significant Industrial User's (SIU's),
fourteen (14) of which are Categorical Industrial User's (CIU's) under the Federal
Code of Regulations. Borg Warner Thermal which was a 433-metal finisher, went
out of business at the end of 2021. The permit was rescinded effective December
31, 2021. MSD added Industry 9 as a 433-metal finisher during the second half of
2021. Therefore, the number of SIU's was twenty-one (21) with fifteen (15) CIU's
during the second half of 2021.
MSD issued fifteen (15) Notice of Violations (NOV's)/Notice of Concerns (NOC's),
with one Civil Penalty of $2,000.00. There are no industries in Significant Non-
Compliance (SNC) for the 2021 calendar year.
MSD completed required sampling for all SIU and CIU industries throughout the
2021 calendar year. One SIU/CIU did not discharge during the 2021 calendar year.

2021 Pretreatment Annual Report Narrative
Metropolitan Sewerage District of Buncombe County (MSD)
NPDES Permit # NCOO24911
Arcadia Farms LLC (S-078)
Arcadia Farms LLC was issued a NOV in July for TRC Violations for both BOD and
TSS. In September, Arcadia Farms LLC spilled 1,000 gallons of orange juice to the
drain resulting in a significant BOD and TSS TRC Violation. Because the spill
caused a significant Violation, MSD issued a Civil Penalty of two thousand dollars
($2,000). The Civil Penalty was paid in a timely manner.
Asheville Metal Finishing (S-003)
Asheville Metal Finishing had a significant decrease in production and discharge
days. Therefore, Asheville Metal Finishing did not sample as frequently as listed in
the permit. Asheville Metal Finishing contacted MSD about the less frequent
discharges. MSD informed Asheville Metal Finishing that they were not required to
pull samples if they were not discharging.
Borg Warner Thermal (S-030)
Borg Warner Thermal gradually reduced production throughout the year and
completed a planned shutdown. All metal finishing operations were moved to
their Mexico facility. The Facility Closed at the end of 2021. MSD closed out the
permit effective December 31, 2021. NCDWR approved the Permit Drop January 6,
2022.

Continental Automotive Systems (S-015)
Continental Automotive Systems was issued a Notice of Violation for a TRC Zinc
Violation. Continental Automotive Systems resampled and issued a corrective
actions report.
Craggy Prison Laundry (S-066)
Craggy Prison Laundry had two separate instances of high flows. Both instances
resulted in incoming water spilling to the ground. Craggy Prison Laundry uses the
incoming flow meter for daily flow numbers. Neither instance resulted in an actual
permit limits violation as the water did not go to sewer. MSD did not issue a NOV
or NOC for either occurrence.
Day International Inc. (S-057)
Day international Inc. reported two flow limits overages in May and July. Both
times the flow meter bubble pressure tube was clogged. Once the clog was cleared
the flow meter showed a significant reduction in flow. Day International Inc. is
working with a vendor to find a suitable replacement of the flow meter.
Eaton Electrical (S-014)
Eaton Electrical - Arden Plant is a batch discharger. MSD sampled at Eaton on
April 29, 2021. Eaton Electrical decided not to discharge. Eaton had the
wastewater hauled off site. The sample results did not show any permit limits
violations. Eaton did not discharge to MSD during the 2021 calendar year. Eaton
has since decided to request a Zero Discharge Permit instead of the current SIU
permit. The application for a Zero Discharge Permit was received February 24,
2022.

LL
C Linamar, L C (S-076))
GF Linamar, LLC was issued a NOV for January for a Phenols and O&G Violation.
They were issued another NOV for two 0&G Violations. One of which was over the
TRC limit. During the time of the Violations, GF Linamar was working with MSD to
update the SIU Permit. The new SIU Permit became effective on April 1, 2021.
NCDWR approved the SIU Permit on March 30, 2021. Since the issuance of the new
SIU permit, GF Linamar has not had any violations.
GF Linamar Submitted plans for additional pretreatment equipment on June 3,
2021. MSD issued an Authorization to Construct (A to C) on June 15, 2021.
Construction of the new pretreatment equipment was complete October 27, 2021.
Kearfott Corporation, Motion Systems Division (S-009)
MSD sampling results from January 27, 2021, showed a Tin of 2.49 mg/L. Kearfott
is not regulated for Tin as it is not regulated under 40 CFR 433. The company was
contacted, and the result was reviewed along with results from previous sampling.
Fifty three percent of the sample results at this location have been below detection.
MSD did not issue a NOV. MSD collected another Tin sample in September which
was below detection.
Meritor Heavy Vehicle Systems (S-061)
Meritor was issued a NOV for Nickel above the TRC limit for April 7, 2021. Results
from Nickel sampling remained below the permitted limit for the remainder of
2021.

19
Milkco, Inc. (S-036)
Milkco, Inc. was issued several NOC's for flow limits violations from February to
July. Later in year it was discovered that the newly installed flow meter was not
recording flow correctly. Milkco is currently using their old flow meter while they
wait on a replacement for the new meter. Supply chain issues are currently
causing delays for flow meters. MSD has a couple of non-SIU's which are having
similar issues receiving flow meters.
Sierra Nevada Brewing Company (S-073)
On February 9, 2021, Sierra Nevada experienced a system upset, the issue was
identified, resolved, and reported the same day. The upset resulted in a TSS

Dear Sir/Madam:
Metropolitan Sewerage District (MSD) of Buncombe County was issued a NPDES discharge permit
(01C0024911),effective October 1, 2018. Section A(8) of the NPDES Permit requires submission of an
annual report stating optimization/construction progress for compliance with the NPDES ammonia
schedule. By December 31, 2021, MSD is to complete the installation of the High-Rate Primary
Treatment(HRPT)system,and initiate performance testing for parameters as listed in the permit. This
letter provides a status update of the HRPT project and identifies way in which MSD will incorporate
operational strategies, optimization procedures and sampling protocols to attain the October 31, 2030,
ammonia limits deadline.
• Shook Construction is the General Contractor for the new HRPT Project. The HRPT
Project Notice to Proceed was issued December 5, 2018, and construction began
January 7, 2019.The HRPT original substantial completion date was October 28, 2020.
The project has experienced significant delays attributable to all of the following:
inclement weather days,delays due to the fire on November 10, 2020, and associated
lead times of replacement equipment, COVID-19 pandemic, labor and supply chain
shortages issues, and Contractor efficiency and workmanship. As a result,the current
contractual substantial completion date is September 1, 2021. Actual substantial
completion is anticipated by February 2022 (HRPT process online)with final completion
in Spring 2022.
• MSD will continue NPDES influent and effluent compliance sampling as per the Permit
and will incorporate additional sampling in the ammonia schedule in preparation of
future reports.A new sampling point will be established beginning as soon as feasible at
the effluent of the HRPT process located north of the headworks removal systems, prior
to entering Rotating Biological Contractor(RBC) Basin number one (1).
• MSD will continue to report annually as the construction project advances and is
completed, and sampling results are collected and summarized. The overall HRPT
optimization will be achieved through operational strategies, sampling analysis and
evaluation.

• Introduction of wastewater into the HRPT began Thursday, December 09, 2021.The
optimization of HRPT treatment train #2 was completed Friday, December 10, 2021.
Grab samples were collected from HRP
T influent and HRPT clarifier effluent.The
optimization of HRPT treatment train#1 began Monday, December 13, 2021, with grab
samples collected the same as HRPT train#2. All samples were delivered to Pace
Laboratories for analysis.
• The acceptance testing for HRPT train#2 is anticipated to begin the week of January 3`d
2022. During acceptance testing 24-hour composite samples will be collected and
delivered to Pace Laboratories for analysis. The HRPT train#1 acceptance testing is
anticipated to begin the week of January 10'h, 2022, and as with train#2, 24-hour
composite samples will be collected and delivered to Pace Laboratories for analysis.
• MSD will begin HRPT performance testing at conclusion of acceptable results of the
HRPT acceptance testing. Influent and effluent HRPT samples will be collected as
outlined in the NPDES ammonia schedule. Data will be compiled and analyzed to
achieve maximum efficiency of the overall wastewater treatment process.
• The COVID 19 pandemic has continued to have long lasting impacts on the world and
has disrupted many of the normal operations of life. Unfortunately,this has occurred
during the course of the HRPT construction project. Due to the pandemic, MSD is
experiencing supply chain disruptions,workforce shortages and economic impacts like
many utilities across the nation. MSD remains committed to the established ammonia
compliance deadline of October 1, 2030 and will continue to comply with the reporting
schedule as outlined in the NPDES Permit. However, MSD is making notice of a general
force majeure for all projects regarding operation, maintenance and pre-established
deadlines in all issued State and Federal Permits. Due to the pandemic and the effects
listed above, MSD is struggling to deliver existing projects on time and may experience
similar impacts on projects in the coming months and years.The impacts on current and
future projects are unforeseen and immeasurable, and no prediction can be made for
how projects will be impacted in the coming years.

Dear Sir/Madam:
This report is written to maintain compliance with Metropolitan Sewerage District(MSD)of Buncombe
County NPDES discharge permit issued October 1, 2018, Section A(8)of the NPDES Permit requires
submission of a wastewater treatment optimization and improvement plan for the ammonia schedule of
compliance. This treatment optimization and improvement plan is outlined in the ammonia compliance
schedule of compliance.As outlined, the compliance schedule will be adhered to by following sound
engineering design, permitting, bidding, planning, scheduling, and construction practices. These tasks
will be incorporated with operational strategies and sampling protocols to attain the October 31, 2030,

• The new WRF headworks, placed in service February 19, 2019,. consisting of% inch bar
screens with compactor, 6 mm fine screens with compactor and vortex grit removal
with washer.A new surge pumping station utilizing the existing repurposed anaerobic
digesters for 4.2 million gallons of storage and a flow split/diversion structure that will
serve as a point of return for flow from the surge pumping station and will be utilized in
the Phase 2 upgrade to tie-in to the new high-rate primary treatment process.
• This new headworks equipment has increased the removal of solids waste from the
wastewater stream. However,there is not a reduction of soluble components of the
wastewater stream,by the headworks equipment.
• The volume of screenable material removed by the bar screens, fine screens, and vortex
grit removal systems from January 1, 2020 to date is 724 cubic yards. This is 49 cubic
yards less than the period of February 19, 2019,to December 31, 2019. The volume
removed by the headworks is dependent on rainfall events which flush the collection
system and the amount of septage hauled to the MSD septage receiving station.
• NPDES Influent and effluent compliance sampling are conducted as per the Permit and
the additional sampling in the ammonia schedule in preparation of future reports. A.
new sampling point will be established beginning as soon as feasible, at the effluent of

• The sampling results demonstrate no reduction of ammonia nitrogen sampled as the
wastewater flows through the new headworks structure. The current total nitrogen
removal rate is 32%and the ammonia nitrogen removal rate is 10%through the Water •
Reclamation Facility(WRF).Additional sampling of in-plant side streams demonstrates
concentrations of ammonia nitrogen being conveyed back to the influent pump station
of the WRF.
• The optimization and improvements will be reported annually as construction projects
are completed and sampling results are summarized: The overall optimization of the
WRF will be achieved through operational strategies, sampling analysis and planned
construction project completion.
• Shook Construction is the General Contractor for the new High-Rate Primary Treatment
Project(HRPT).The HRPT Project Notice to Proceed was issued December 5, 2018 and
construction began January 7, 2019. The HRPT original substantial completion date was
October 28, 2020. As the project progressed there has been projecfcreep, inclement
weather days and scheduling issues, which moved the substantial completion date to
February 8, 2021.
• On November 10, 2020, MSD experienced a major catastrophic fire of the warehouse
• located above the Water Reclamation Facility, This warehouse contained most of the
MSD's pumps, emergency piping, mobile lighting and twenty(20)spare Rotating
Biological Contractors(RBC's). Unfortunately,this warehouse also housed new
equipment that was to be installed in the HRPT. Much of this equipment has long lead
times from different venders/suppliers. At the December 2"d construction meeting the
contractor's prediction is substantial completion on August 22, 2021,with the final
completion on October 21, 2021. However, equipment suppliers projected lead times
are 26 weeks for some of the equipment lost in the fire, so substantial and final
completion dates could be moved further into the future. MSD will maintain the
reporting schedule as outlined in the ammonia schedule.

Re: Wastewater Treatment Optimization and Improvement Plan
NPDES Permit # NC0024911—Section A. (8) Ammonia Schedule of Compliance
Dear Sir/Madam:
This report is written to maintain compliance with Metropolitan Sewerage District (MSD) of
Buncombe County's NPDES discharge permit issued October 1, 2018. Section A. (8) [Ammonia
Schedule of Compliance] of the NPDES Permit requires submission of a Wastewater Treatment
Optimization and Improvement Plan by December 31, 2019. The Plan must define steps being
taken by MSD to achieve the future ammonia limits as defined in Section A. (1) of the permit.
As outlined below, compliance will be achieved by following sound engineering design,
permitting, bidding, planning, scheduling and construction practices. These tasks will be
incorporated with operational strategies and sampling protocols to attain the October 1, 2030
ammonia limits deadline. The following items satisfy the requirements of reporting:
• MSD issued a Notice to Proceed for the new Water Reclamation Facility (WRF)
Headworks Improvements project on April 3, 2018. The headworks improvements
provide improved screening and grit removal at the plant, and a significant reduction
in solids deposition in the downstream biological basins. The result is increased
treatment volume and hydraulic residence time (HRT).
Prior to the project, the existing climber screens passed a significant amount of rags
and large debris that caused maintenance problems for downstream processes and
impacted the ability of these processes to perform at their peak efficiency. The poor
performance of the grit and grease removal facility also contributed to the
aforementioned maintenance problems and have been upgraded as well.
In addition, the existing abandoned anaerobic digester tanks were utilized for
emergency storage to allow peak flow mitigation during storm events. Equalizing
flow through the plant provides a more stable, reliable treatment system.
Protecting Our Natural Resources-
2028 RIVERSIDE DRIVE, ASHEVILLE,NORTH CAROLINA 28804 TELEPHONE:[phone] FAX:[phone] WEBSITE:www.msdbc.org

The Headworks Improvements project included the following:
• Replacement of the existing 3/" influent climber screens with new 1/2"
traveling rake type screens.
• A new Y4" fine screening facility to be used in conjunction with the new
coarse influent screens
• A new vortex grit removal facility
• A new surge pumping station utilizing the existing out of service digesters for
4.2 MG of wet-weather storage
• A flow split/diversion structure that will serve as a point of return for flow
from the surge pumping station, and will be utilized in the Phase 2 upgrade
to tie-in to the new high rate primary treatment process. The diversion
structure will also facilitate maintenance of plant operations during
construction of the HRPT system.
• Demolition of the existing grit and grease removal facility.
• It should be noted that this upgrade raised the plant hydraulic grade line in
preparation for future plant upgrades. To allow this, MSD replaced their existing
pump impellers with a higher impeller trim as part of their normal pump
maintenance/replacement cycle. This project improved reliability of plant
equipment and reduced equipment maintenance, improved overall operational
efficiency, helped extend the lives of the existing RBCs, and established the hydraulic
profile for the planned future upgrades. This project did not change plant design
flowrate, biological treatment processes, filtration, disinfection, or solids handling at
the existing facility. The new WRF headworks was placed in service February 19,
2019.
• The volume of screenable and settleable material removed from the bar screens,
fine screens and vortex grit removal systems are measured and recorded for
comparison to historical data. (see attached graph)
• NPDES influent and effluent compliance sampling are conducted per the Permit
which for this annual g
sam lin report are adequate. A new point will be established
p p
beginning January 1, 2020 at the splitter box located north of the vortex grit removal
system prior to entering Rotating Biological Contractor (RBC) Basin number one (1).
This location is the influent for the High Rate Primary Clarifier (HRPC) when
construction is completed. The samples will be collected on a weekly basis for NH3-
N, total N, total BOD and soluble BOD.
• The sampling of NH3-N, total N, total BOD and soluble BOD will continue as specified
in the Ammonia Schedule for Compliance as outlined in the NPDES Permit. (Copy of
Ammonia Schedule of Compliance attached for you convenience)
• The optimization and improvements will be reported annually as construction
projects are completed and sampling results are summarized. The overall
optimization of the WRF will be achieved through operational strategies, sampling
analysis and planned construction project completion.

• Shook Construction is the General Contractor for the new High Rate Primary
Treatment (HRPT) project. The HRPT project Notice to Proceed was issued January
7, 2019 with a contract completion date of January 9,2021.
If there are questions or concerns regarding this report please, do hesitate to contact Roger
Edwards, Water Reclamation Facility ORC, at [e-mail] or 828-225-8224.
