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 ioo,000 gallon per day (GPD) package treatment plant which was replaced in
2oi8-2019. The new package plant consists of the following:
• Mechanical bar screen,
• 25,000 gallon aerated equalization tank
• Dual train 37,500 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 2oii, 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 ioo 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
73.7o 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 (13A (an expansion of 13),
14,15C,16, and 18) were constructed and brought online in 2o18 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 2o18. 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, 2o18). This 2021 report serves as the third submittal of an
annual report to satisfy this requirement.
A deadline for the first and subsequent annual reports was not explicitly provided in the permit. During a conference
call with NC Department of Environmental Quality (DEQ) representatives, Butterball and Dewberry on November 7,
2o18, a submittal date of March 1, 2019 was agreed upon for the first reporting period of January 1, 2o18 — December
31, 2o18. Subsequent annual reports, as long as required by the permit, will be submitted by March 1 each year.

Groundwater Monitoring Well Data
2020 Monitoring Well Data
Table 1 summarizes the monitoring well data collected during the reporting period January 1, 2020 — December 31,
202o. Analysis of 202o data in the context of historical data is provided in subsequent sections.
In 202o, exceedances of groundwater standards were observed in three wells for at least one parameter. An
exceedance of the nitrate standard was observed in MW-22 during the May sampling event, in MW- 38 for all three
sampling events, and in MW-39 for the May sampling events. An exceedance of the total dissolved solids (TDS)
standard was observed in MW-38 during the May sampling event. During the September sampling event, five wells
were tested for fecal coliform at a method detection limit above the 1 most probable number per ioo mL (MPN/ioo
mL). All five results were reported as less than 5 MPN/ioo mL.
Nine monitoring wells did not experience exceedances of the groundwater standards for any parameter during 2020
sampling events. No exceedances were observed for total phosphorus (TP), ammonia -nitrogen, nitrite -nitrogen, and
chloride in any of the wells in 2020.
Historical Data Analvsis
Monitoring well sampling results from 2oo8-2020 were analyzed in order to evaluate trends in groundwater results.
This period was selected as operations at the Butterball facility prior to 2oo8 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 250 mg/1 was exceeded in MW-27 in 2oo8. Chloride has not exceeded the
standard during any other sampling events since 2oo8 and therefore will not be discussed further in this report.
The total dissolved solids (TDS) groundwater standard of 500 mg/1 was exceeded in five monitoring wells in 2oo8
(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 8 of the past io 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
2011-2020. MW-27 has also experienced consistent exceedances of the nitrate groundwater standard. MW-38 and
MW-27 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-39 in 2019-202o and MW-40 in 2oi8-2019; 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 02L.0102). Compliance boundary is
defined as a boundary around a disposal system at and beyond which groundwater quality standards may not be
exceeded (15NCAC 02L.0102). With the exception of MW-40, all groundwater exceedances since 2oo9 have occurred
have been observed 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-40, 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
MW-38 is the only monitoring well that exceeded the TDS standard in 202o. The TDS concentration in MW-38 has
exceeded the groundwater standard of 500 mg/l in ii of the 29 samples collected from 2011-202o. Figure 1 presents
the MW-38 TDS groundwater concentration and the cumulative mass of TDS applied to the Fields 1A,1B, and 1C
which are immediately upgradient of MW-38.

y�
The MW-38 groundwater concentration appears to correlate fairly well to the mass of TDS applied to Fields 1A,1B,
and 1C. The decline in MW-38 TDS concentration observed in January 2014, September 2o16, September 2o18, and
September 202o are preceded by decreases in the mass of TDS applied to 1A,1B, and 1C. In addition, the increase in
MW-38 concentration observed in January and May 2017 and May and September 2oi9 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 address in the Corrective Action section.
Nitrate
Nitrate has consistently exceeded the groundwater standard in MW-27 and MW-38. MW-38 is downgradient of fields
1A,1B, and 1C. 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 1A,1B, and 1C.

61" Dewberry"
y�
The MW-38 nitrate concentration correlates at times with operation of the fields 1A,1B, and 1C. Decreases in nitrate
concentration observed in September 2o16 and May 2o18 are preceded by decreases in the mass of TN applied to
these fields. However, the trend in MW-38 and TN loading to fields 1A,1B, and 1C do not always correlate. An
increase in nitrate concentration observe in May 2o16 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 202o after a period of increased loading on fields 1A,1B, and 1C and then declined in May
and September 2020 when loading also declined.
Figure 3 presents the MW-27 nitrate groundwater concentration with the total mass of total nitrogen applied to the
Fields 7 and 7A.

Mass Applied to Fields 7 and 7A f MW-27 Nitrate-N Concentration 30per. Mov. Avg. (Mass Appliedto Fields 7 and 7A)
MW-27 nitrate results show significant variability over time and do not correlate well with the nitrate mass applied to
upgradient fields 7 and 7A. The MW-27 nitrate concentration declined significantly from May 2oo8 to September
2oo8 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
2o18 without a corresponding increase in the total nitrogen loading to upgradient fields. The MW-27 nitrate results
do correlate to increases and decreases in nitrate loading to fields 7 and 7A. The long-term average nitrate
concentration in MW-27 is below the groundwater standard of io mg/l.
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 202o 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 2o18. Prior to the installation of the new fields, the average daily volume
applied to Fields 1A,1B, and 1C was 320,000 gpd from 2oo8 - 2017. In 2o18 immediately after the new fields were
brought online, the average daily volume applied was 233,000 gpd, which represents a 27% reduction. In 2019, the
average daily volume applied to Fields 1A,1B and 1C continued to decrease to 184,000 gpd, a 42% reduction from
pre-2o18 loading rates. The 202o average daily loading of Fields 1A,1B, and 1C was 192,000 gpd, which represents a
40% reduction from pre-2018 rates. 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 2o18, 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 1B 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 1B and suggest that the selected maintenance
improved performance of the field.
Butterball replaced the sanitary package pretreatment plant in 2o18 with construction completed in 2o19. 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 1C 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 1A, 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 1C, 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 1-A,1B, and 1C, and
upgraded sanitary pretreatment plant will have an impact on MW-27 and MW-38 nitrate results. In 2021, Butterball
plans to initiate rehabilitation activities on fields 2C, 3, 7A and 8C.

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 1A, 1B, and 1C. Maintenance of Fields 1A and 1C is completed as of this report date. A steady
decline in TDS concentrations in MW-38 were observed in 2o18, 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 2021 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 2o18, allowing Butterball to initiate maintenance
activities for Field 1B the same year. Since initiating operation of the new fields, Butterball has reduced hydraulic
loading to Fields 1A, 1B, and 1C by at least 40%.
Butterball completed maintenance activities at Field 1B in 2018-2oi9. Butterball targeted Field 1B initially as it is the
single largest field and is upgradient of MW-38. Maintenance activities for Fields 1A and 1C 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
1B 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 1A and 1C maintenance is completed
and the impact of these activities should continue to be evaluated.
