Subject: 2023 Pretreatment Mailing
Dear Pretreatment Professionals:
NORTH CAROLINA
Environmental Quality
1/20/2023
At the beginning of another pretreatment year, we wanted to provide you with an update on some
important issues and distribute the Pretreatment Program Info Database sheets.
1. Emerging Compounds: The Division requests you review the 12/5/2022 EPA Memo titled
Addressing PFAS Discharges in NPDES Permits and Through the Pretreatment Program
and Monitoring Programs. DWR may request local pretreatment programs conduct an
emerging contaminant (EC) screening for new Significant Industrial Users (SIUs) and
additional guidance is forthcoming.
2. The Industrial Database: The Division has a subscription to Industry Select an online
industrial database from Manufacturers News, Inc. Industrial information for your POTW's
service area can be downloaded and emailed to you upon request. POTWs must complete
an Industrial Waste Survey (IWS) upon each renewal of the NPDES Permit and an Industry
Select download with SIC / NAICS info is a good way to get started.
Permit Review and Approval: This is a reminder that the State Pretreatment rules (.0900)
were updated effective on July 1, 2019. Per 15A NCAC 02H .0917(a), each control
authority shall transmit to the Division copies of all significant industrial user
pretreatment permits 30 days prior to the effective date. Please note that approved permit
writers can submit the IUPs at the time of issuance. More details can be found on the Permit
Writing Guidance oage.
4. Industrial Waste Survey (IWS,) Table: There is a redesigned the Industrial Wastewater
Survey Summary Table to use for your POTW's submission to the NPDES Municipal
Permitting Unit for review and approval. Please download this spreadsheet use it to
document your IWS efforts. We welcome any comments or suggestions on your experience
with this updated document.
5. POLs & Over Allocations: The Division issued a "PQL Data Handling" letter on March 21,
2022 to address Headworks Analysis over allocation issues. Options presented allow for
adjustments based upon conditional POC analysis using the appropriate PQL. The
Pretreatment Consortium recently drafted a revised detection level chart which will be
reviewed and approved for distribution soon.

9. Pretreatment Program Info Database Sheets• Please review your attached program info
sheet(s) and historical SNC sheet(s), if applicable, and make necessary updates to any of the
information presented. Send the corrected sheets back with your PAR, due March 1, 2023,
for calendar year 2022. If all the information was correct, please indicate that in your PAR.
Especially note the due dates as this may be the only reminder you get. Please contact
Pretreatment staff if have any questions about this process.
Please note:
a. All pretreatment programs (full and modified) must submit a Pretreatment Performance
Summary (PPS) Form with their PAR per an EPA requirement of the State.
b. PAR forms are available for download on our website.
10. Pretreatment SNC Database for 2016 - 2022: If you received Historical SNC sheet(s), for
only active SLUs, please make (bold with notes) corrections and additions and send (in pdf
format) to Pretreatment Staff so we can attempt to update this important information.
11. Email Addresses: The Municipal Permitting Unit often uses email to send out mass
mailings. To make this an effective and cost saving tool, we ask that you keep the Municipal
Unit updated on your current email address as well as which staff member is the "primary"
contact for your POTW - see "prim" field next to staff names on Program Info sheet, and
email field below names. For programs with more staff than the printed sheet can show, a
separate contacts page has been included. Please make any staff changes on that sheet and
return to the Municipal Unit with the PAR.
As always, please contact pretreatment staff members (as listed above) with any questions or
comments.

Mr. Marcus Bell
Mountaire Farms, Inc.
1101 East Third Street
Siler City, North Carolina 27344
RE: Notice of Significant Non -Compliance
Dear Mr. Bell,
For the first six -months reporting period of 2022, Mountaire Farms Inc. is in Significant Non -Compliance (SNC). In
accordance with the Town of Siler City Sewer Use Ordinance and the Town's Enforcement Response Plan (ERP), the Town
of Siler City herby issues Mountaire Farms, Inc. a Notice of Violation (NOV) as described below.
1. SNC NOV for Pass through at the wastewater treatment plant, stemmed from high BOD discharges coming from
your pretreatment unit. See attachment A for dates exceeded limits.
The Town of Siler City arrived at this compliance status based on the nature of the violation. The Ordinance states:
Sec. 27-81 Definitions
"Pass through means a discharge which exits the POTW into the 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 the violation, of the POTW's NPDES or non -discharge permit, or a downstream water quality standard."
Sec. 27-81 Definitions Significant Noncompliance 1) c.,d.
c. Any other violation(s) of an effluent limit (average or daily maximum) that the control authority believes has
caused, alone or in combination with other discharges, interference or pass -through; or endangered the health of the
sewage treatment plant personnel or the public.
d. Any discharge of a pollutant that has caused imminent endangerment to human health or welfare or to the
environment or has resulted in the POTW's exercise of its emergency authority to halt or prevent such a discharge.
To support you in preventing a second SNC violation, The Town hereby issues you a temporary suspension of the
weekly flow average located in Mountaire's Pretreatment permit IUP 004, Part 1 F (1) footnote 2 noted below, for the
second six-month reporting period of 2022.

RE: Notice of Significant Non -Compliance
Mr. McCorquodale,
This correspondence is in response to the receipt of the Notice of Significant Non -Compliance received on
September 16, 2022. This letter will provide information requested by the Town including changes already
made to Mountaire's wastewater facility and future plans for Mountaire Farms.
The following items were completed to aid in water quality:
1. A change in coagulants was made in March 2021 in the primary DAFs. Ferric chloride was already
used in the secondary DAFs but as of March 2021, ferric chloride is used in both primary and
secondary treatment. Ferric chloride being used in both primary and secondary treatment allows for
additional removal of SOD and phosphorus.
2. Beginning in October 2021, bacteria was added to the final equalization tank to reduce BOD.
Additional air was also added to aid in BOD reduction.
3. Hydrogen peroxide was also used in the equalization tank during two different periods in 2021 during
bacteria addition for additional air and to reduce BOD.
4. Another sodium hypochlorite feed line was added to the final equalization tank in May 2022.
5. Sodium bi-sulfite was added in August 2022 to reduce the total chlorine levels leaving the wastewater
facility.
The following items are scheduled to be to be completed in the future:
1. Currently wastewater enters the primary equalization tank, then flows to the primary DAFs and finally
treated in the secondary DAFs. After secondary treatment, the pre-treated wastewater is stored in the
final equalization tank where the flow is discharged to the Town of Siler City daily. With the flow
restriction added in January 2021 requiring flow to be averaged over 7 days, pre-treated wastewater
remains in the final equalization tank for much longer causing degradation of the wastewater, especially
during hot weather, before it flows to the Town. A trial involving the change of the wastewater flow in
the current system will be made. After the system controls are changed and approval is given by the
Town, the flow will go through primary treatment, then flow to the final equalization tank. The last step
will be secondary treatment before it is discharged to the Town. The trial will begin after the control
changes have been made at the Mountaire wastewater facility.
2. Mountaire has met with a construction company and engineer to discuss upgrades to the current
wastewater system. The focus of these discussions will be to improve water quality by reducing BOD.
These discussions are in the preliminary phase. Plans for the future will involve design and
construction which will be a multi -year project. Mountaire will communicate with the Town through each
step of the plans and will submit the appropriate applications and request the proper approvals before
moving forward.

RE: Mountaire Farms Inc. IUP 004
Mr. McCorquodale,
This correspondence is in response to a previous discussion regarding both short and long-term plans at the
Mountaire Farms Siler City Wastewater Facility located at 1101 East Third Street Siler City, North Carolina
27344. A short-term plan to aid in increased water quality involves the change of the flow pattern throughout
the wastewater facility. The current wastewater flows through the primary DAFs, then to the secondary DAFs,
and lastly to the equalization tank before discharge. The wastewater held in the equalization tank increases in
volume throughout the week, causing biological activity and degradation of the wastewater after treatment.
Mountaire has been working through the controls programming with a consultant to change the flow pattern
through the wastewater facility. The new proposed flow pattern starts with treatment through the primary
DAFs, then the wastewater would flow to the equalization tank and end with treatment through the secondary
DAFs. Treatment after the equalization tank and right before discharge should improve water quality.
Mountaire plans to perform a test on November 19, 2022. This test with the consultant will change the
program from the current flow pattern to the new flow pattern for approximately four hours. This test will be
used to make sure the flow, pumps and levels are maintained appropriately. This program change can easily
be switched back if needed. After the test on November 19, 2022 has proved successful, Mountains will
request in writing a trial period for the new flow pattern. During this time, Mountaire requests that the Town
continue to share their laboratory data so as to know the changes in water quality as soon as the results are
known.
Mountaire's long-term plans include construction of a wastewater upgrade to include a new equalization tank,
MBBR tanks for BOD and ammonia removal and equipment buildings. The upgrade is currently in the design
phase. As the design and construction schedule are available, Mountaire will share all information with the
Town and work through the permitting process when the design is complete.
If you have any questions, need additional information or would like to discuss this matter further, please
contact me at [phone].

RE: Mountaire Farms Inc. IUP 004
Mr. McCorquodale,
This correspondence is meant as a follow-up to the Mountaire Short and Long -Term Plans letter dated November 4, 2022
for the Mountaire Farms Siler City Wastewater Facility located at 1101 East Third Street Siler City, North Carolina 27344.
A short-term plan to aid in increased water quality involves the change of the flow pattern throughout the wastewater
facility. The current wastewater flows through the primary DAFs, then to the secondary DAFs, and lastly to the
equalization tank before discharge. The wastewater held in the equalization tank increases in volume throughout the

starts with treatment through the primary DAFs, then the wastewater would flow to the equalization tank and end with
treatment through the secondary DAFs. Treatment after the equalization tank and right before discharge should improve
water quality.
Mountaire did perform this test on November 19, 2022 as scheduled. The test was used to make sure the flow, pumps
and levels were maintained appropriately. This program change can easily be switched back if needed. Because the test
on November 19, 2022 proved successful, Mountaire is now requesting a trial period lasting 90 calendar days to switch to
the new flow pattern. During this time, Mountaire requests that the Town continue to share their laboratory data so as to
know the changes in effluent water quality as soon as possible.
If you have any questions, need additional information or would like to discuss this matter further, please contact me at

RE: Change of Flow Pattern
Mrs. Rogers -Vickers,
In responds to your request for short-term flow pattern trail, requested on November 22, 2022, the Town does
grant your request for short-term flow pattern adjustment for a length of 60 calendar days, starting December
10, 2022 — February 10, 2023 with the following provisions:
1. This short-term flow pattern does not in any way reduce or change Mountaire's responsibility to meet
their permit limits or their sampling requirements.
2. The Town will continue to sample Mountaire, as required in our permit and will stay in contact on a
weekly basis or more as needed to ensure that progress and compliance is being meet.
3. The Town reserves the right to cease this trail at any time if the receipt of the waste is proven to be a
causal factor in any detrimental treatment of plant performance.
The current wastewater flows through the primary DAFs, then to the secondary DAFs, and lastly to the
equalization tank before discharge. The new flow pattern starts with treatment through the primary DAFs, then
the wastewater would flow to the equalization tank and end with treatment through the secondary DAFs.
As we move closer to the end of the short-term flow pattern trial, it is proven to be successful and Mountaire
wishes to continue to this new flow pattern we will have a more in-depth conversation as to the next steps.
If you should have any questions, please let me know.
Sincerely,
/f
