Introduction
Butterball operates a turkey processing facility in Mt Olive, NC. The facility operates a 2 million gallon per day (MGD)
wastewater treatment plant for the treatment of process wastewater prior to land application under the auspices of
Wastewater Irrigation System Permit WQ0000884.
Sanitary wastewater is pretreated in a 100,000 gallon per day (GPD) package treatment plant which was replaced in
2018-2019. The new package plant consists of the following:
• Mechanical bar screen,
• 25,000 gallon aerated equalization tank
• Dual train 31,500 gallon each aeration tanks
• Dual train 22,000 gallon each clarifiers, and
• Associated piping, valves, and controls.
Treated sanitary wastewater is discharged to the 13 million gallon (MG) lagoon which is part of the industrial
wastewater plant described below.
The industrial wastewater treatment plant consists of the following:
• 1 MG flow equalization tank with mixers
• Two dissolved air flotation (DAF) units with polymer feed
• A DAF sludge pump station
• DAF sludge storage tank
• DAF sludge decant observation tank
• 13 MG aerated lagoon with five 6o HP surface aerators
• 41 MG holding lagoon with three 20 HP surface aerators
• Chlorine disinfection, and
• Associated piping, valves, and controls.
Upgrades to the wastewater treatment system have been continuously performed by Butterball to improve operation
and performance of the plant and reduce loading on the spray irrigation fields. In 2011, Butterball began using
peracetic acid in the production facility which resulted in lower wastewater effluent volumes. In 2011 Butterball also
upgraded the DAF and offal system to improve performance of the wastewater treatment system, in particular to
enhance nitrogen, phosphorous, suspended solids, and organics removal.
Effluent from the 41 MG lagoon is pumped via four loo HP pumps and two 5o HP booster irrigations to the spray
irrigation system. The spray irrigation system is currently permitted for 556.88 acres with 35 fields, which includes
13.70 acres of newly permitted fields. These fields were added by Butterball in 2017 in order to upgrade and expand
the irrigation system to reduce loading on the existing fields. The additional acreage will allow for existing fields to be
periodically removed from service to perform maintenance activities. Five of the new fields (i3A (an expansion of 13),
14, 15C, 16, and 18) were constructed and brought online in 2018 for a cumulative additional acreage of 48.66 acres.
Six of the fields (15A, 15B, 17A, 17B, 17C, and 17D) with a cumulative acreage of 25.04 acres have been permitted but
have yet to be constructed. A site plan for the land application system is provided as the attached Figure 1.
In addition to the 2017 spray irrigation system upgrade, Butterball again modified the permit to upgrade the WWTP
in 2018. This upgrade included replacement and enhancement of the sanitary wastewater pretreatment system to
increase nitrogen, phosphorous, suspended solids, and organics removal and thereby reduce loading on the fields.
Recent permit issuances included a new requirement for Butterball to submit an annual report summarizing any
exceedances of permitted monitored well limits and corrective action taken. This requirement is found in Section I(6)
of the most recent issuance of WQ0000884 (May 11, 2018). This 2022 submittal satisfies this requirement. Annual
reports are submitted by March 1 each year.

Groundwater Monitoring Well Data
2021 Monitoring Well Data
Table i summarizes the monitoring well data collected during the reporting period January 1, 2021 — December 31,
2021. Analysis of 2021 data in the context of historical data is provided in subsequent sections.
In 2021, exceedances of groundwater standards were observed in four wells for at least one parameter. An exceedance
of the nitrite standard was observed in MW-22 during the May and September sampling events. An exceedance of the
nitrate standard was observed in MW- 38 for May and September sampling events, as well as in both MW-39 and
MW-41 for the all three sampling events. During the May and September sampling events, MW-22 was tested for fecal
coliform at a method detection limit above the groundwater standard of 1 most probable number per loo mL
(MPN/ioo mL). Results were non -detect at 5 MPN/ioo mL.
Eleven monitoring wells did not experience exceedances of the groundwater standards for any parameter, during
2021 sampling events. The pH for all wells was below the groundwater standard range for at least two and sometimes
all three sampling events. No exceedances were observed for ammonia -nitrogen, total dissolved solids (TDS), and
chloride in any well in 2021.
Historical Data Analysis
Monitoring well sampling results from 2008-2021 were analyzed in order to evaluate trends in groundwater results.
This period was selected as operations at the Butterball facility prior to 2008 were different enough from current
operations that a comparative analysis is less meaningful. Table 2 attached presents a summary of parameter
exceedances by year and monitoring well.
The chloride groundwater standard of 25o mg/1 was exceeded in MW-27 in 2008. Chloride has not exceeded the
standard during any other sampling events since 2008 and therefore will not be discussed further in this report.
The total dissolved solids (TDS) groundwater standard of 50o mg/1 was exceeded in five monitoring wells in 2008
(MW-23, MW-24, MW-27, MW-3o, and MW-34). An exceedance of the TDS groundwater standard occurred in 2015
in MW-21; however, this is an upgradient well and is not impacted by irrigation activities. The TDS groundwater
standard has been exceeded in MW-38 during 9 of the past 11 years. Additional analysis of the TDS results in MW-38
will be addressed below.
The nitrate groundwater standard of io mg/1 was exceeded in MW-38 in at least one sampling event per year from
2011-2021. MW-27 has also historically experienced consistent exceedances of the nitrate groundwater standard,
however, an exceedance of the nitrate groundwater standard has not occurred at MW-27 since the January 2018
sampling event. Nitrate exceedances have been observed in MW-39 in 2019-2021. MW-38 and MW-39 nitrate results
will be analyzed in additional detail below. Nitrate exceedances in other wells have been sporadic, do not represent a
trend, and therefore will not be analyzed in additional further in this report. Nitrate exceedances have been observed
in MW-4o in 2018-2019 and MW-41 in 2021; however, those two wells were installed in 2017 and historical data is
not available.
Butterball currently monitors 15 wells which include review boundary and compliance boundary wells. Review
boundary is defined as a boundary around a permitted disposal facility, midway between a waste boundary and a
compliance boundary at which groundwater monitoring is required (15A NCAC o2L.olo2). Compliance boundary is
defined as a boundary around a disposal system at and beyond which groundwater quality standards may not be
exceeded (15NCAC o2L.olo2). With the exception of MW-4o, all groundwater exceedances since 2009 have occurred
in review boundary wells. An exceedance of groundwater standards at a review boundary well is not necessarily
indicative of an exceedance at the compliance boundary or at the Butterball property line. Corrective action taken by
Butterball to address exceedances at the review boundary wells are described herein. It should be noted that MW-4o,
which was installed in 2017, is a compliance boundary well but it is downgradient of Fields 15A and 15B which have
not been constructed.

Total Dissolved Solids
No monitoring well exceeded the TDS standard in 2021. MW-38 is the only monitoring well that exceeded the TDS
standard in 2020. The TDS concentration in MW-38 has exceeded the groundwater standard of 50o mg/1 in 11 of the
31 samples collected from 2011-2021. Figure 1 presents the MW-38 TDS groundwater concentration and the
cumulative mass of TDS applied to the Fields iA, 1B, and iC which are immediately upgradient of MW-38.

The MW-38 groundwater concentration appears to correlate fairly well to the mass of TDS applied to Fields iA, 1B,
and iC. The decline in MW-38 TDS concentration observed in January 2014, September 2016, September 2018, and
September 2020 are preceded by decreases in the mass of TDS applied to iA, 1B, and iC. In addition, the increase in
MW-38 concentration observed in January and May 2017 and May and September 2019 are preceded by an increase
in the TDS mass applied to these fields. The MW-38 TDS concentration appears to be impacted by operation of the
sprayfields. Ongoing activities to address this impact are addressed in the Corrective Action section.

Nitrate
Nitrate has historically exceeded the groundwater standard in MW-27 and MW-38. MW-38 is downgradient of fields
iA, 1B, and iC. These three fields collectively represent 112.82 acres which is 21% of the total active sprayfield area.
MW-27 is downgradient of fields 7 and 7A. These two fields collectively represent 15.69 acres which is 2.9% of the
total active sprayfield area. Active area refers to the 531.84 acres that have been constructed to date.
Attachment A presents a map showing the average nitrate concentration at each well across the Butterball site.
Attachment A demonstrates that exceedance of nitrate groundwater standards is not a wide -spread issue at the site
but rather is isolated to two monitoring wells, MW-27 and MW-38. A historical analysis of MW-27 and MW-38
nitrate concentrations versus loading to upgradient fields is presented below. MW-39 is noted on Attachment A as
having an average nitrate concentration above io mg/l. However MW-39 is located next to a field that has not been
constructed and the elevated nitrate is not likely the result of impacts of spray irrigation.
Figure 2 presents the MW-38 nitrate groundwater concentration and the cumulative mass of total nitrogen applied
daily to the Fields iA, 1B, and iC.

Mass TN Applied to 1A, 1B, 1C t Nitrate-N Concentration
The MW-38 nitrate concentration correlates at times with operation of the fields iA, 1B, and iC. Decreases in nitrate
concentration observed in September 2016 and May 2018 are preceded by decreases in the mass of TN applied to
these fields. However, the trend in MW-38 and TN loading to fields iA, 1B, and iC do not always correlate. An
increase in nitrate concentration observe in May 2016 and September 2017 are preceded by periods of declining
nitrogen loading on the fields. In addition, the nitrate concentration declined continuously from September 2013
through September 2014 during a period when nitrogen loading on the fields was continuously increasing.
Additionally, in 2019, the nitrate concentration in Mw-38 increased when January and May 2019 samples were

collected after a period of declining mass loading on these fields. In 2020 the nitrate concentration in MW-38
increased in the January 2020 after a period of increased loading on fields iA, 1B, and iC and then declined in May
and September 2020 when loading also declined. The nitrate concentration in MW-38 during January 2021 sampling
event decreased to below the groundwater standard. In 2021, the nitrate concentration increased from the January
sampling event to the May sampling event to above the groundwater standard and decreased to just above the
groundwater standard in the September sampling event.

MW-27 nitrate results show significant variability over time. Historically the nitrate mass applied to upgradient fields
7 and 7A has not correlated with the MW-27 nitrate results. However since 2019, the nitrate concentration at MW-27
has remained below the groundwater standard and the nitrate result for MW-27 does correlate well with the mass of
nitrate applied to fields 7 and 7A. The MW-27 nitrate concentration declined significantly from May 2008 to
September 2008 during a period when nitrogen loading to the upgradient fields was relatively stable. In addition, the
MW-27 nitrate concentration decreased significantly from May 2015 to September 2015 during a period when the
nitrogen loading to upgrade fields was increased. The MW-27 concentration increased sharply in September 2017 to
January 2018 without a corresponding increase in the total nitrogen loading to upgradient fields. The long-term
average nitrate concentration in MW-27 is below the groundwater standard of io mg/1.
MW-38 and MW-27 nitrate concentrations do not consistently correlate well to the mass of nitrogen applied to the
fields. It is not clear at this time what is causing nitrate groundwater standard exceedances in MW-27 and MW-38;
however, it is likely a combination of multiple factors such as historical operation of the fields, precipitation,
background nitrate from upgradient agricultural sources, and wastewater composition including parameters such as
biochemical oxygen demand and salts. The May 2020 results from the background well MW-22 exceeded the
groundwater standard. Salts applied to the fields can impact infiltration rates, which can impact treatment efficiencies
in the system. Biochemical oxygen demand must be available for denitrification of nitrate to occur within the soil
matrix. Maintenance activities described below are intended to address salt build up in the fields and improve
infiltration rates.

Corrective Action
Butterball has undertaken multiple steps to address groundwater standard exceedances for nitrate and TDS in review
boundary well MW-27 and review boundary well MW-38. In 2017, Butterball expanded and upgraded their irrigation
system to permit an additional 73.7 acres of irrigable acreage. This additional acreage has allowed Butterball to reduce
hydraulic and constituent loading on the fields. Currently, Butterball has constructed 48.66 acres of the new fields
and began using the additional area in 2018. Prior to the installation of the new fields, the average daily volume
applied to Fields iA, 1B, and iC was 320,00o gpd from 2008 — 2017. The reduction in irrigation volume for Fields iA,
1B, and iC can be seen in Table 3 below. Even with significant reduction in volumetric loading, MW-38 data indicated
exceedances in the groundwater standard in 2020.

In addition, Butterball will use the additional acreage to periodically remove fields from service for maintenance
activities. In September 2018, Field 1B, the single largest permitted field, was removed from service and has
undergone a series of disking and idle periods in order to allow for degradation of organic matter that has
accumulated in the field. In addition to disking and idle periods, gypsum addition occurred in January 2019 to
improve the exchangeable sodium percentage of the fields. Prior to rehabilitation, only 25% of Field iB was
functioning within normal soil and infiltration conditions. Post -rehabilitation analysis indicates that after
rehabilitation over 89% of the field area was functioning within normal soil and infiltration conditions. Interim
results indicate a >800% increase in the infiltration rates within Field iB and suggest that the selected maintenance
improved performance of the field.
Butterball replaced the sanitary package pretreatment plant in 2018 with construction completed in 2019. This
upgrade will enhancement the sanitary wastewater pretreatment system to increase nitrogen, phosphorous,
suspended solids, and organics removal and thereby reduce loading on the fields.
Butterball removed Fields iA and iC from service in November 2019. Pre -rehabilitation soil analysis was performed
followed by a series of disking and gypsum addition and idle periods. Post -rehabilitation sampling was performed in
March 2020. Prior to rehabilitation of Field iA, only 21.8% of the fields were functioning within soil and infiltration
condition while post -rehabilitation 95.4% of the field was within normal limits. Prior to rehabilitation of Field iC, no
portion of the field was operating within normal limits for soil and infiltration conditions and post -rehabilitation
93.2% was within normal limits. Following the rehabilitation, additional trenching was installed in Field iA to provide
drainage for two depressions that were consistently wet.
Butterball will closely observe if the additional irrigable acreage, maintenance activities on Field iA, 1B, and iC, and
upgraded sanitary pretreatment plant will have an impact on MW-27 and MW-38 nitrate results. In 2021, Butterball
completed rehabilitation activities on fields 2C, 3 and 7A. Rehabilitation activities for fields 8B and 8C are projected
to finish in 2022.

Conclusion
Groundwater monitoring wells have demonstrated periodic exceedances of nitrate and TDS standards at the
Butterball facility. TDS exceedances have been isolated to MW-38 since 2009. MW-38 TDS results correlate with
operation of Fields iA, 1B, and iC. Maintenance of Fields iA and iC is completed as of this report date. A steady
decline in TDS concentrations in MW-38 were observed in 2018, likely as a result of the reduced loading due to
addition of new fields. Sampling data from MW-38 has shown an overall decreasing trend. Butterball will observe the
TDS results during 2022 to evaluate if maintenance activities have continued to impact TDS results in MW-38.
Nitrate exceedances have sporadically occurred in multiple monitoring wells across the site but have largely been
isolated to review boundary wells MW-27 and MW-38. Attachment A demonstrates that exceedance of nitrate
groundwater standards is not a wide -spread issue at the site but rather is isolated to two monitoring wells, MW-27
and MW-38. Analysis of historical nitrogen loading to upgradient fields for each monitoring well does not
demonstrate strong correlation with the MW-27 and MW-38 nitrate concentrations. However, the groundwater
nitrate concentration is impacted by a variety of factors such as infiltration rates, availability of organic constituents
to support denitrification in the soil matrix, and the nitrogen available to support crop production.
Butterball has permitted 73.7 acres of additional irrigable acreage in order to reduce hydraulic and contaminant
loading on existing fields. The additional acreage will also allow for existing fields to be removed from service
periodically for maintenance. New fields were made operational in 2018, allowing Butterball to initiate maintenance
activities for Field iB the same year. Since initiating operation of the new fields, Butterball has reduced hydraulic
loading to Fields iA, 1B, and iC by at least 23%.
Butterball completed maintenance activities at Field iB in 2018-2019. Butterball targeted Field iB initially as it is the
single largest field and is upgradient of MW-38. Maintenance activities for Fields iA and iC were initiated in
November 2019 were completed in March 2020.
Butterball is currently taking actions to address groundwater exceedances. Improvement has already been observed
in MW-38 monitoring results with the reduced loading from addition of new fields. Results of maintenance on Field
iB suggests that field performance will be improved by the actions taken and, if the MW-38 are largely impacted by
irrigation, an improvement in MW-38 results will be observed over time. Field iA and iC maintenance is completed
and the impact of these activities should continue to be evaluated.
