DESCRIPTION OF FACILITY
Tyson Fresh Meats, Inc. (Tyson) is a food processing facility of beef and pork products. The facility also has cold storage for the products. The facility is a case-ready facility,
which receives meat from another facility that has slaughtered the animal. This process discharges process wastewater to the Eagle Mountain City (Eagle Mountain) Publicly Owned Treatment
Works (POTW).
Tyson has been classified as a Significant Industrial User (SIU) due to the flow volume and pollutant load discharged to the Eagle MountainPublicly Owned Treatment Works (POTW) 40 Code
of Federal Regulations (CFR) 403.3 (v)(1)(ii). Due to Tyson being an SIU, a pretreatment permit is necessary. Also, due to Eagle Mountain not having an Approved POTW Pretreatment Program
(Program), the Division of Water Quality (DWQ) is the Control Authority; therefore, the Permit will be issued by DWQ. Once Eagle Mountain has a Program, it will issue the pretreatment
permit.
Daily facility operations consist of two shifts working from 6 AM until 1 AM Monday through Friday and some Saturdays. The operation shuts down for holidays and weekends.
The facility has a treatment system. The system includes an equalization tank (EQ tank), screening, a gas energy mixing (GEM) system and solids removal. The treatment system is overseen
by the maintenance group, which has several staff members to ensure it is adequately maintained and operated. The treatment system is operated via a supervisory control and data acquisition
(SCADA) system, which sends alarms if it is not operating correctly. Generally, the GEM system is operated automatically by the SCADA system based on the level controls within the treatment
system. No changes are currently planned for the treatment system.
Carne Corp hauls the solids from the treatment system off-site. According to Part I.D of the UPDES Permit, hauled waste records must be maintained and include the volume and disposal
location of the hauled waste.
PERMIT CHANGES
The Permit language has been modified to be consistent with revisions to the pretreatment permit. These changes are consistent with requirements that the Permittee should already be
implementing or added language to clarify the Permit requirement.
DESCRIPTION OF DISCHARGE
Wastewater is generated from cutting, bagging, and cleaning as part of the production process. Daily discharge from the production floor is estimated at an average of 110,000 gallons
per day (gpd). The Permit limits the facility to 500,000 gpd.This is to ensure the load allocation for total suspended solids (TSS) and biochemical oxygen demand for 5 days (BOD5) is
not exceeded and to ensure the POTW is not overallocating for TSS, BOD5 or flow.
Wastewater is also discharged from non-contact cooling water,which is estimated at an average of 62,000 gpd. The discharge of process wastewater and cooling water will be continuous
throughout the day.
Outfall 001 is the monitoring location for the facility and is located at a latitude of 40° 18’02.6” North and a longitude of 112° 04’40.5” West. Process wastewater will not be comingled
with non-process wastewater at the discharge point.
EFFLUENT LIMITATIONS
The limitations for TSS and BOD5are based on an allocation allowed by Eagle Mountain. These parameters are load-based limitations to protect the POTW Treatment Plant from becoming overloaded.

The limitation for oil and grease is based on protecting the POTW from Pass Through and Interference. This ensures the collection system is not impacted by the oil and grease from the
Tyson facility. This limit could be lowered if the POTW notices oil and grease within the collection system. However, this has not occurred since the issuance of the Permit; therefore,
the limit will remain at 250 mg/L.
The daily minimum pH limit is based on the prohibited standard in UAC R317-8-8.5(3)(b). The daily maximum pH limit is based on not allowing waste that would otherwise be classified as
hazardous waste to be discharged to the POTW, 40 CFR 261.22. The limit is slightly more stringent than stated in 40 CFR 261.22(a)(1), which is a pH of 12.5 standard units (SU). This
limit also protects the POTW and POTW personnel from wastewater that could be corrosive. The daily maximum limit is 12.0 SU.
The effluent limitations listed in the Effluent Limitations Table in Part I of the Permit will apply to the effluent from the Tyson Facility before entering the POTW. Additional parameters
must be monitored to determine the need to develop pretreatment standards for the POTW, as stated in the Self-Monitoring and Reporting Requirements Table. The additional monitoring
requirements are not listed in the limit table due to the parameters not currently being limited by the Permit. If a limit is developed and approved by DWQ, the Permit will be modified
to incorporate the limit into the Permit.

MONITORING AND REPORTING REQUIREMENTS
Monitoring requirements and measurement frequencies are based on the parameter being limited by the Permit or the need for data to develop a local limit. The sample types are based on
requirements for the parameter or requirements in 40 CFR 403.12 (g)(3) or 40 CFR 136. The wastewater discharge shall be sampled as specified in the Self-Monitoring and Reporting Requirements
Table. Samples, unless otherwise stated, must be collected utilizing flow-proportioned sampling techniques. All monitoring results and observations shall be summarized on a discharge
monitoring report (DMR) form for each month. The Permit requires reports to be submitted monthly, as applicable, on Discharge Monitoring Report (DMR) forms due 28 days after the end
of the monitoring period. Monitoring results shall be submitted using NetDMR. DMRs must either be submitted with monitoring data included or indicate no discharge occurred for the monitoring
month. The DWQ will take annual samples to determine compliance with effluent limitations. The cost of the analysis will be billed to the Permittee. The POTW will also be able to sample
the effluent and recover expenses for sampling or analyzing any parameters to determine the need to develop local limits or ensure compliance with the Permit. Tyson must notify the
DWQ Director and the POTW of any Permit violations, including spills or changes at the facility. If a sample result violates a Permit requirement, it must be reported within 24 hours
of becoming aware of the violation. Also, a resample of the violated Permit requirement must occur, with the results being submitted to DWQ within 30 days of becoming aware of the violation.
Also, notification of bypasses of any treatment units utilized to treat the process wastewater from the processing plant must be reported to DWQ and Eagle Mountain. If notification must
occur to the city, it must be provided to the public works director and the city manager or mayor. If the POTW does not have a public works director at the time of notification, the
notification must be made to the city manager or mayor and the direct responsible charge (DRC) for the wastewater treatment plant or collection system.
Samples can be collected utilizing time-proportioned composite samples for the parameters listed in the Permit. Timed proportioned samples will be allowed so long as aliquots are taken
every 10 minutes. Timed samples will be allowed since the system is running effectively and seems to be in a steady state.
Samples for pH and oil and grease must be collected using a grab sample.Outfall 001 Self-Monitoring and Reporting RequirementsParameterFrequencySample TypeUnitsTotal Flow ContinuousRecorderMGD

BIOMONITORING REQUIREMENTS

As part of a nationwide effort to control toxicity, biomonitoring requirements are included in permits for facilities where effluent toxicity is an existing or potential concern. Tyson
discharges to a POTW;therefore,biomonitoring will not be required at this time. Biomonitoring of the effluent will not be necessary unless a potential for toxicity is discovered. Authorization
for requiring effluent biomonitoring is provided in UAC R317-8-4.2 and R317-8-5.3.
PRETREATMENT REQUIREMENTS
Any wastewater that Tyson discharges to a sanitary sewer, either as a direct discharge or as a hauled waste, is subject to Federal, state of Utah,and local pretreatment regulations.
Pursuant to Section 307 of the Clean Water Act, the Permittee shall comply with all applicable Federal General Pretreatment Regulations promulgated in 40 CFR 403, the state of Utah
Pretreatment Requirements found in UAC R317-8-8, and any specific local discharge limitations developed by the POTW accepting the waste.
SLUG CONTROL PLAN
Tysonhas been evaluated for a slug control plan,which was determined to be unnecessary. Per the requirements of R317-8-8, DWQ will continue to evaluate the facility for a slug control
plan. Since the issuance of the UPDES Permit, a spill has not occurred within the facility that has been discharged to the POTW.
The Facility must immediately notify the DWQ and the POTW of spill or slug changes or potential changes that could impact the POTW. For more detailed information on the storage, hazards
and location of chemicals and spill containment, see the Tysonpermit application Sections H, I and J.
Floor drains are located in the manufacturing area, which discharge to the EQ tank. Best management practices are in place on the manufacturing floor to ensure the process wastewater
system is not overwhelmed by the manufacturing process. This includes gathering scraps from the floor rather than allowing the scraps to be discharged into the system.
If changes occur where a slug control plan is needed, DWQ will notify Tyson of the requirement. Following the notification, Tyson will have 90 days to develop a slug control plan as
required in the UPDES Permit Part I.F.STORM WATERThePermit includes storm water requirements that require the Permittee to obtain and maintain permits if a permit is needed due to activities
at the Facility. See Part IV of the Permit for requirements. The primary industrial activity codes at the Facility are classified under the North American Industry Classification System
(NAICS) Code as 311612. The requirement to obtain coverage under the Multi-Sector General Permit (MSGP) for Storm Water Discharges Associated with Industrial Activities is defined by
a Facility’s Standard Industrial Classification (SIC) Code. The equivalent SIC code for this Facility requires permit coverage under Sector C, and the Permittee currently has coverage,
UTRI00022. The following link provides additional information regarding the UPDES Industrial Stormwater Permit: https://deq.utah.gov/water-quality/general-multi-sector-industrial-storm-water-permit-updes-permits
Permit coverage under the Construction General Storm Water Permit (CGP) is required for any construction at the Facility that disturbs an acre or more or is part of a common plan of
development or sale that is an acre or greater. A Notice of Intent (NOI) is required to obtain a construction storm water permit during construction. The following link provides additional
information regarding the UPDES Construction General Storm Water Permit: https://deq.utah.gov/water-quality/general-construction-storm-water-updes-permitsGeneral UPDES Stormwater Permit
requirements can be found at: http://stormwater.utah.govPERMIT DURATIONIt is recommended that this Permit be effective for less than five (5) years. This will allow for an extension,
if needed, when the Permit is renewed. This is beneficial as the requirements of 40 CFR 403 do not allow a pretreatment permit to be issued for more than five (5) years. PUBLIC NOTICE
