Dear Dr. Adaryani,
On behalf of Pickles Manufacturing, LILC (formerly Bay Valley Foods, Dean's Pickles), TRC Engineers
Inc. (TRC, formerly Draper Aden Associates) is pleased to present the 2022 Annual Chloride Reduction
Report for the Faison, NC, facility.
In accordance with Special Condition A. (5) b.: NPDES Permit No. NCO001970, Pickles Manufacturing,
LILC-Faison, NC, continues efforts to study and evaluate chloride removal technologies and chloride
reduction strategies. Enclosed please find a copy of the facility's 2022 Annual Chloride Reduction
Report. Throughout the 1980's, 1990's and 2000's significant investments were made on process
improvements, new equipment purchases, and process change strategies aimed at reducing salt use
and subsequent chloride discharges. Notable investments and process changes include the
replacement of wooden fermentation tanks, reduction of salt concentration in brines, process
automation, and brine recycling technology. These efforts resulted in substantial reduction in salt use,
with subsequent focus on pollution prevention efforts further reducing chloride discharges to surface
water. As noted in previous Annual Chloride Reduction Evaluation Reports, there have been no recent
economically feasible advances in chloride removal technologies applicable to the production
processes employed at Pickles Manufacturing, LLC — Faison, NC. Efforts continue to improve process
control and automation with a focus on reducing brine loss and salt waste.
If you have any questions or comments, please contact us at 919-423-2016.

1.0 Basic Information
Pickles Manufacturing, LLC (formerly Bay Valley Foods) — Faison, INIC (PM), remains committed
to continuing efforts to maintain the downward trend in chloride discharges from its production
facility. Through emphasis on its comprehensive pollution prevention, advanced process control
and automation aimed at reducing brine loss, replacement of inefficient equipment and ongoing
efforts in the identification and implementation of new and innovative reduction opportunities,
PM maintains its focus on the reduction of chlorides in its waste stream (Chart 1). PM will
continue to investigate and monitor technological advances that may have potential application
to the pickle processing industry and supports research efforts in this area through its
membership in professional trade organizations such as Pickle Packers International. PM is
willing to implement cost-effective chloride removal technologies and pollution reduction
measures that can be proven effective and not compromise or impair finished product quality
and/or characteristics.
2.0 Production
PM uses an established formula whereby all production types, in all facilities, are normalized.
The normalized unit of measure is referred to as an "Equivalent Production Unit" and allows for
a fair and equal comparison of differing sized containers from a 1 O-ounce jar to 5-gallon bucket.
The Equivalent Production Unit (EPU) brings all production to a case equivalent volume and
enables a fair comparison of production between facilities and production years and provides a
balanced method to evaluate performance.
The Faison, INIC facility production requirements increased annually from 1996 through 2006 at
which time, production peaked at 9.04 million EPU (Tables 2.1 and 2.2). Since 2006, the
production throughput has generally decreased (Chart 2). The 2022 production volume was
5.15 million EPU, a 15.5% decrease from the 2021 volume (6.10 million EPU) (Table 2.1). The
2022 average ratio of chloride discharged in pounds per EPU (0.37) is slightly above the 1996 —
2022 average ratio (0.32) and, also, above the 2018 - 2022 five-year average ratio (also 0.32)
(Table 2.2). Due to the ongoing commitment from facility leadership, the pounds of chloride
discharged per EPU continue to show a long-term downward trend of approximately 0.006
pounds discharged per EPU per year (Chart 3).

4.0 Technologies and Approaches Considered for 2022 and Beyond
Many projects, programs, process changes, and chloride reduction strategies that were
implemented in the past continued to be utilized into 2022 as described in the following
sections.
4.1 Bypass Salting / No Fermentation Process
The proprietary "No Fermentation" process continues to be a significant process improvement
and chloride reduction strategy and will be considered for all future production opportunities
where applicable.
4.2 Desalt Process Improvements
The Faison facility added four portable de -salt tanks for product de -salting. The de -salting
process must be accomplished quickly to support the production schedule, which can result in
over de -salting of the product necessitating the re -addition of salt. The result is excess water
use, increased salt use and ultimately additional chloride discharges. The four portable de -salt
tanks enabled the facility to extend the duration of the de -salt process, which provided improved
process control.
Status: Successful process improvements were made to the de -salt process in 2009. Cost
Associated with Improvements - $350,000.
4.3 Brine Reclaim Process Improvement — 5-Gallon Pail Line
The installation of catch pans, filter screens, and a brine reclaim tank on the 5-gallon pail line
allows for the capture of overflow brine and eventual reuse, rather than discharged as high
chloride concentrated wastewater.
Status: Successful improvements were made to the brine reclaim system on the 5-gallon pail
processing line in 2009. Cost Associated with Improvements - $4,500.

4.4 Wastewater Treatment Process Improvements
Excess biomass accumulation in Pond 3 was removed and the pond was relined. This project
was completed in April 2017. In 2017, PM removed biomass accumulation from Pond 1 and
began the process to re -line Pond 1. Sludge removal and liner replacement was completed in
March 2018. Pond 1 aerators were re -wired, and the pond was returned to normal operations
on May 1, 2018. An additional 280 tons of sludge was removed in 2021, and 2,231 tons of
sludge was removed in 2022 at a cost of $51,850 .
Status: Successful improvements were made to the wastewater ponds. Sludge removal costs
to date - $347,850.
4.5 Pickle Packers International (PPI)
PM is a member of, and continues to participate in, the Pickle Packers International
organization. Through participation in this organization, PM remains current on new processing
technologies which may include reduced salt use, and wastewater treatment strategies others in
the pickle processing industry may have implemented that result in reduced chlorides in
wastewater discharges.
4.6 Treatment Technologies
Ramboll Environ prepared a Chloride Removal Technology Evaluation Report dated January
12, 2017. The report identified several technologies potentially applicable to the PM facility.
The technologies included reverse osmosis, electrodialysis / electrodialysis reversal, chemical
precipitation, product substitution, flow augmentation, and residuals management. PM is
committed to investigating and evaluating any new treatment technology based on technical
applicability and feasibility.
5.0 Waste Reduction
The ongoing waste reduction efforts at the Facility have continued through 2022.
The facility has formed a cross -functional Pollution Prevention Team (Team) that meets on a
regular basis to discuss and evaluate waste generation and chloride reduction opportunities. A
comprehensive pollution prevention program is in place which includes educating employees
regarding waste best management practices and the importance of identifying strategies that
can reduce chloride discharges. Chloride reduction is a primary focus of the Team along with
water conservation, efficient utilization of energy, and minimizing waste generation. In addition,
the Team considers maintenance practices and other protocols that may result in brine loss.
Finally, the Team is continually evaluating processes for redesign consideration with respect to
improved efficiency and chloride discharge reduction opportunities.
In combination with waste reduction and pollution prevention efforts, PM continues to focus on
preventive maintenance programs and giving a priority assignment to any maintenance work
order involving process equipment that could result in increased discharge of chlorides. These
activities along with employee training help foster and expand a work ethic focused on waste
reduction as well as process improvements.

The maximum daily discharge for each month in 2022 was below the daily maximum limit and
the average monthly discharge was below the monthly average limit (Table 6.0 and Chart 4).
Upstream chloride concentrations represent background values. An anomalous peak in
downstream chloride concentrations observed in 2007 was attributed to low stream flow
conditions throughout the year, a result of drought conditions. Linear regressions performed on
chloride stream concentrations found in Table 7 indicate decreasing trends (negative slopes) in
Downstream Points #1 and #3, and a slightly increasing trend (positive slope) in Downstream
Point #2 (Chart 5).
The total annual chloride discharge generally decreased from 2007 to 2015 (Table 2.2, Chart 6).
From 2015 through 2021, chloride discharges have fluctuated, but have remained well below
the 2007 level. The provided charts demonstrate that waste reduction efforts at the PIVI facility
are effective.
