FACT SHEET AND STATEMENT OF BASIS GARLAND CITY MUNICIPAL WASTEWATER TREATMENT PLANT (WWTP) RENEWAL PERMIT: DISCHARGE, BIOSOLIDS UPDES PERMIT NUMBER: UT0026034 UPDES BIOSOLIDS PERMIT NUMBER: UTL-026034 MINOR MUNICIPAL FACILITY CONTACTSPerson Name:Skylar HachmeisterPosition:Public Works DirectorPhone Number:(435) 257-3118Facility Name:Garland City Wastewater Treatment PlantMailing Address:PO Box 129 Garland, UT 84312Telephone:(435) 257-3118 Actual Address:1206 South 1050 East Garland, UT 84312 DESCRIPTION OF FACILITY The Garland City Wastewater Treatment Plant (Garland WWTP) is a new activated sludge facility located at 1206 South 1050 East in Garland, Utah. The treatment process is designed for an average flow of 0.45 MGD and a peak flow of 0.90 MGD. The facility has a preliminary treatment process consisting of an in-channel automated screen with bagging mechanism, a manual bypass bar rack and a vortex grit chamber, classifier and screw conveyor. The secondary treatment process consists of biological assimilation of organics through aerobic cellular metabolism. Phosphorous is removed from the wastewater during secondary clarification. Onsite waste activated sludge is stabilized, thickened, and reduced through endogenous respiration. The facility uses ultra-violet light (UV) disinfection. Waste by-products, including screenings and dewatered biosolids, are hauled to the Box Elder County Landfill. DISCHARGE DESCRIPTION OF DISCHARGE Garland WWTPhas been reporting self-monitoring results on Discharge Monitoring Reports on a monthly basis. Garland WWTP began to discharge in April 2022. During the first 18 months of operations, the Garland WWTP transitioned multiple different operatorsthrough as the Direct Responsible Charge (DRC). During some periods of time DMRs were not submitted, and some of the monitoring results were lost. This was noted, and a Warning Letter was sent to Garland City regardingthese deficiencies in December 2023, and the DMR have been submitted regularly since then. Summary of three years of data is included in Attachment 2 of this FSSOB.OutfallDescription of Discharge Point 001 Located at latitude 4143'42" and longitude -11209'00". The discharge will be through a steel encased pipe to the Malad River. RECEIVING WATERS AND STREAM CLASSIFICATION The final discharge flows into the Malad River, in the Bear River watershed. The Malad River is classified as 2B and 3C according to Utah Administrative Code (UAC) R317-2-13: Class 2B -- Protected for infrequent primary contact recreation. Also protected for secondary contact recreation where there is a low likelihood of ingestion of water or a low degree of bodily contact with the water. Examples include, but are not limited to, wading, hunting, and fishing. Class 3C -- Protected for nongame fish and other aquatic life, including the necessary aquatic organisms in their food chain. TOTAL MAXIMUM DAILY LOAD (TMDL) REQUIREMENTS According to the Utah’s Final 2024 Integrated Report on Water Quality dated April 30, 2024, the receiving water for the discharge, “Malad River and tributaries, from confluence with Bear River to state line (Assessment Unit Malad River-1, AU ID: UT16010204-006_00)” was listed as “Not Supporting” for Benthic Macroinvertebrates Bioassessments, E. coli, Thalium, and pH. A TMDL is needed, however, the priority is set to “Low”. There was an approved TMDL completed in 2002 for Total Phosphorous.The downstream reach “Bear River and tributaries, from Great Salt Lake to Utah-Idaho border, except as listed below (Assessment Unit Bear River-2-2, AU ID: UT16010204-008_02)” was listed as “Not Supporting” for Benthic Macroinvertebrates Bioassessments and Total Dissolved Solids. A TMDL is needed, however, the priority is set to “Low”. BASIS FOR EFFLUENT LIMITATIONS Limitations on total suspended solids (TSS), biochemical oxygen demand (BOD5), E. coli, pH and percent removal for BOD5 and TSS are based on current Utah Secondary Treatment Standards, UAC R317-1-3.2. The oil and grease is based on best professional judgment (BPJ). Attached is a Wasteload Analysis for this discharge into the Malad River. It has been determined that this discharge will not cause a violation of water quality standards. An Antidegradation Level II review is not required since the Level I review shows that water quality impacts are minimal. The permittee is expected to be able to comply with these limitations. Reasonable Potential Analysis Since January 1, 2016, DWQ has conducted reasonable potential analysis (RP) on all new and renewal applications received after that date. RP for this permit renewal was conducted following DWQ’s September 10, 2015 Reasonable Potential Analysis Guidance (RP Guidance).There are four outcomes defined in the RP Guidance: Outcome A, B, C, or D. These Outcomes provide a frame work for what routine monitoring or effluent limitations are required A review of the metals results shows they were only required to sample twice for metals. This is due to the newness of the facility, lack of any significant industrial sources, and the relatively small volume the discharge will contribute to the Malad River. This is not a large enough sample size to evaluate the RP for a parameter. As a result, no quantitative RP analysis was performed.

SELF-MONITORING AND REPORTING REQUIREMENTSThe following self-monitoring requirements are the same as in the previous permit. The permit will require reports to be submitted monthly and annually, as applicable, on Discharge Monitoring Report (DMR) forms due 28 days after the end of the monitoring period. Effective January 1, 2017, monitoring results must be submitted using NetDMR unless the permittee has successfully petitioned for an exception. Lab sheets for biomonitoring must be attached to the biomonitoring DMR. Lab sheets for metals and toxic organics must be attached to the DMRs.

After the solids are tested or treated, the solids are then known as biosolids. Class A biosolids, may be used for high public contact sites, such as home lawns and gardens, parks, or playing fields, etc. Class B biosolids may be used for low public contact sites, such as farms, rangeland, or reclamation sites, etc. DESCRIPTION OF TREATMENT AND DISPOSAL Garland WWTP dewaters the biosolids and transports them to the Box Elder County Landfill along with other materials removed during the treatment process. SELF-MONITORING REQUIREMENTS Under 40 CFR 503.16(a)(1), the self-monitoring requirements are based upon the amount of biosolids disposed per year and shall be monitored according to the chart below. Minimum Frequency of Monitoring (40 CFR Part 503.16, 503.26, and 503.46) Amount of Biosolids Produced, Processed, or Disposed of Per Year Monitoring Frequency Dry US Tons Dry Metric Tons Per Year or Batch > 0 to < 320 > 0 to < 290 Once Per Year or Batch > 320 to < 1650 > 290 to < 1,500 Once a Quarter or Four Times > 1,650 to < 16,500 > 1,500 to < 15,000 Bi-Monthly or Six Times > 16,500 > 15,000 Monthly or Twelve Times Garland WWTPgenerates and disposes of less than 100 DMT of biosolids a year, therefore they could be required to sample once a year. Landfill MonitoringUnder 40 CFR 258, the landfill monitoring requirements include a paint filter test. If the biosolids do not pass a paint filter test, the biosolids cannot be disposed in the sanitary landfill (40 CFR 258.28(c)(1). BIOSOLIDS LIMITATIONS Heavy MetalsClass A Biosolids for Home Lawn and Garden UseThe intent of the heavy metals regulations of Table 3,40 CFR 503.13 is to ensure the heavy metals do not build up in the soil in home lawn and gardens to the point where the heavy metals become phytotoxic to plants. The permittee will be required to produce an information sheet (see Part III. C. of the permit) to made available to all people who are receiving and land applying Class A biosolids to their lawns and gardens. If the instructions of the information sheet are followed to any reasonable degree, the Class A biosolids will be able to be land applied year after year, to the same lawns and garden plots without any deleterious effects to the environment. The information sheet must be provided to the public, because the permittee is not required, nor able to track the quantity of Class A biosolids that are land applied to home lawns and gardens.Class A Requirements With Regards to Heavy Metals If the biosolids are to be applied to a lawn or home garden, the biosolids shall not exceed the maximum heavy metals in Table 3 below. If the biosolids do not meet these requirements, the biosolids cannot be sold or given away for applications to home lawns and gardens.Class B Requirements for Agriculture and Reclamation Sites The intent of the heavy metals regulations of Tables 1, 2 and 3, of 40 CFR 503.13 is to ensure that heavy metals do not build up in the soil at farms, forest land, and land reclamation sites to the point where the heavy metals become phytotoxic to plants. The permittee will be required to produce an information sheet (see Part III. C. of the permit) to be handed out to all people who are receiving and land applying Class B biosolids to farms, ranches, and land reclamation sites (if biosolids are only applied to land owned by the permittee, the information sheet requirements are waived). If the biosolids are land applied according to the regulations of 40 CFR 503.13, to any reasonable degree, the Class B biosolids will be able to be land applied year after year, to the same farms, ranches, and land reclamation sites without any deleterious effects to the environment. Class B Requirements With Regards to Heavy Metals If the biosolids are to be land applied to agricultural land, forest land, a public contact site or a reclamation site it must meet at all times: The maximum heavy metals concentration limits listed in 40 CFR Part 503.13(b) Table 1 and the heavy metals loading rates in40 CFR Part 503.13(b) Table 2; or The maximum heavy metals in 40 CFR Part 503.13(b) Table 1 and the monthly heavy metals concentration limits in 40 CFR Part 503.13(b) Table 3.

If any 1 (one) of these parameters exceeds the Table 3 limit, the biosolids may be land applied or beneficially reused on an agricultural, forestry, reclamation site, or other high potential public contact site, as long as it meets the requirements of Table 1, Table 2, and Table 4. 4, APLR - Annual Pollutant Loading Rate - The maximum annual loading for any 1 (one) of the parameters listed that may be applied to land when biosolids are land applied or beneficially reused on agricultural, forestry, or a reclamation site, when they do not meet Table 3, but do meet Table 1.Any violation of these limitations shall be reported in accordance with the requirements of Part III.F.1. of the permit.If the biosolids do not meet these requirements they cannot be land applied. PathogensThe table below presents Pathogen Control Class limitations that must be met. Pathogen Control Class 503.32 (a)(1) - (5), (7), (8), Class A 503.32 (b)(1) - (5), Class B B Salmonella species –less than three (3) MPN1per four (4) grams total solids (DWB)2 or Fecal Coliforms – less than 1,000 MPN per gram total solids (DWB). Fecal Coliforms – less than 2,000,000 MPN or CFU3 per gram total solids (DWB). 503.32 (a)(6) Class A—Alternative 4 B Salmonella species –less than three (3) MPN per four (4) grams total solids (DWB) or less than 1,000 MPN Fecal Coliforms per gram total solids (DWB), And - Enteric viruses –less than one (1) plaque forming unit per four (4) grams total solids(DWB) And - Viable helminth ova –less than one (1) per four (4) grams total solids (DWB) 1 - MPN – Most Probable Number 2 - DWB – Dry Weight Basis 3 - CFU – Colony Forming Units Class A Requirements for Home Lawn and Garden Use If biosolids are land applied to home lawns and gardens, the biosolids need to be treated by a specific process to further reduce pathogens (PFRP), and meet a microbiological limit of less than less than 3 most probable number (MPN) of Salmonella per 4 grams of total solids (or less than 1,000 most probable number (MPN/g) of fecal coliform per gram of total solids) to be considered Class A biosolids (40 CFR 503.32(a)(7)(i)). At this time Garland WWTPdoes not intend to distribute biosolids to the public for use on the lawn and garden and thus is not required meet Class A Biosolids requirements currently. The practice of sale or giveaway to the public is an acceptable use of biosolids of this quality as long as the biosolids continue to meet Class A standards with respect to pathogens. If the biosolids do not meet Class A pathogen standards the biosolids cannot be sold or given away to the public, and the permittee will need find another method of beneficial use or disposal. Pathogens Class B If biosolids are to be land applied for agriculture or land reclamation the solids need to be treated by a specific process to significantly reduce pathogens (PSRP). At this time Garland WWTPdoes not intend to distribute bulk biosolids for land application and thus is not required meet Class B Biosolids requirements currently. Vector Attraction Reduction (VAR) If the biosolids are land applied Garland WWTP will be required to meet VAR through the use of a method of listed under 40 CFR 503.33. At this time Garland WWTPdoes not intend to distribute biosolids to the public for beneficial use, and will be disposing of them in a landfill.Under 40 CFR 503.33(b)(11) If the biosolids do not meet a method of VAR, the biosolids cannot be land applied. If the permittee intends to use another one of the listed alternatives in 40 CFR 503.33, the Director and the EPA must be informed at least thirty (30) days prior to its use. This change may be made without additional public notice Landfill Monitoring Under 40 CFR 258, the landfill monitoring requirements include a paint filter test to determine if the biosolids exhibit free liquid. If the biosolids do not pass a paint filter test, the biosolids cannot be disposed in the sanitary landfill (40 CFR 258.28(c)(1)). Record Keeping The record keeping requirements from 40 CFR 503.17 are included under Part III.G. of the permit. The amount of time the records must be maintained are dependent on the quality of the biosolids in regards to the metals concentrations. If the biosolids continue to meet the metals limits of Table 3 of 40 CFR 503.13, and are sold or given away the records must be retained for a minimum of five years. If the biosolids are disposed in a landfill the records must retained for a minimum of five years. Reporting For calendar years during which biosolids are produced and/or processed the Garland WWTPmust report annually as required in 40 CFR 503.18. This report is to include the results of all monitoring performed in accordance with Part III.B of the permit, information on management practices, biosolids treatment, and certifications. This report is due no later than February 19 of each year. Each report is for the previous calendar year. MONITORING DATA The Garland WWTP dewaters and landfills all biosolids generated at the facility. As a result of this, they have not been required to monitor and report on any pollutants or pathogens for the biosolids. STORM WATER MSGP coverage is required for Treatment Works treating domestic sewage or any other sewage sludge or wastewater treatment device or system, used in the storage, treatment, recycling, and reclamation of municipal or domestic sewage, including lands dedicated to the disposal of sewage sludge that are located within the confines of the facility, with a design flow of 1.0 million gallons per day (MGD) or more, or required to have an approved pretreatment program under 40 CFR Part 403. If the facility is not already covered, it has 30 days from when this permit is issued to submit the appropriate Notice of Intent (NOI) for the MSGP or exclusion documentation. Permit coverage under the Construction General Storm Water Permit (CGP) is required for any construction at the facility which disturb 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 prior to the period of construction. Information onstorm water permit requirements can be found at http://stormwater.utah.gov PRETREATMENT REQUIREMENTS The permittee has not been designated for pretreatment program development because it does not meet conditions which necessitate a full program. The flow through the plant is less than five (5) MGD, there are no categorical industries discharging to the treatment facility, industrial discharges comprise less than 1 percent of the flow through the treatment facility, and there is no indication of pass through or interference with the operation of the treatment facility such as upsets or violations of the POTW's UPDES permit limits. Although the permittee does not have to develop a State-approved pretreatment program, any wastewater discharges to the sanitary sewer are subject to Federal, State and local regulations. Pursuant to Section 307 of the Clean Water Act, the permittee shall comply with all applicable Federal General Pretreatment Regulations promulgated, found in 40 CFR 403 and the State Pretreatment Requirements found in UAC R317-8-8. An industrial waste survey (IWS) is required of the permittee as stated in Part II of the permit. The IWS is to assess the needs of the permittee regarding pretreatment assistance. The IWS is required to be submitted within sixty (60) days after the issuance of the permit. If an Industrial User begins to discharge or an existing Industrial User changes their discharge the permittee must resubmit an IWS no later than sixty days following the introduction or change as stated in Part II of the permit. It is required that the permittee submit for review any local limits that are developed to the Division of Water Quality for review. If local limits are developed it is required that the permittee perform an annual evaluation of the need to revise or develop technically based local limits for pollutants of concern, to implement the general and specific prohibitions 40 CFR, Part 403.5(a) and Part 403.5(b). This evaluation may indicate that present local limits are sufficiently protective, need to be revised or should be developed. BIOMONITORING REQUIREMENTS A nationwide effort to control toxic discharges where effluent toxicity is an existing or potential concern is regulated in accordance with the Utah Pollutant Discharge Elimination System Permit and Enforcement Guidance Document for Whole Effluent Toxicity Control (biomonitoring), dated February 2018. Authority to require effluent biomonitoring is provided in Permit Conditions, UAC R317-8-4.2, Permit Provisions, UAC R317-8-5.3 and Water Quality Standards, UAC R317-2-5 and R317 -2-7.2. Since the permittee is a new facility, the permit will require whole effluent toxicity (WET) testing. For this permit cycle Garland City WWTP will be required to conduct Acute Wet tests quarterly alternating between Ceriodaphniadubia and Pimephalespromelas (fathead minnows) test species. If no toxicity is observed for 10 consecutive tests, testing frequency may be reduced or removed if approved by the Director in accordance with administrative procedures for modifying the permit. Decisions on type of WET testing and species were based on the revised UPDES Permitting and Enforcement Guidance Document for Whole Effluent Toxicity Control dated February 2018. The permit will also contain the standard requirements for accelerated testing upon failure of a WET test and PTI (Preliminary Toxicity Investigation) and TRE (Toxicity Reduction Evaluation) as necessary. PERMIT DURATIONIt is recommended that this permit be effective for a duration of five (5) years.Drafted and Reviewed byDaniel Griffin, Discharge Permit Writer, Biosolids, Reasonable Potential AnalysisJennifer Robinson, PretreatmentLonnie Shull, BiomonitoringMike Allred, TMDL/Watershed Chris Schope, Wasteload AnalysisUtah Division of Water Quality, (801) 536-4300PUBLIC NOTICEBegan: Month Day, 2025Ended: Month Day, 2025Comments will be received at: 195 North 1950 West PO Box 144870 Salt Lake City, UT 84114-4870The Public Noticed of the draft permit was published on the Division of Water Quality Public Notice Webpage.During the public comment period provided under R317-8-6.5, any interested person may submit written comments on the draft permit and may request a public hearing, if no hearing has already been scheduled.

As a result of the model, more parameters may be included in the renewal permit. A Copy of the Reasonable Potential Analysis Guidance (RP Guide) is available at water Quality. There are four outcomes for the RP Analysis. They are; Outcome A:A new effluent limitation will be placed in the permit. Outcome B:No new effluent limitation. Routine monitoring requirements will be placed or increased from what they are in the permit, Outcome C:No new effluent limitation. Routine monitoring requirements maintained as they are in the permit, Outcome D:No limitation or routine monitoring requirements are in the permit. A review of the metals results shows they were only required to sample twice for metals. This is due to the newness of the facility, lack of any significant industrial sources, and the relatively small volume the discharge will contribute to the Malad River. Initial screening for metals values that were submitted through the discharge monitoring reports showed that no closer look at some of the metals is needed. A copy of the initial screening is included in the “Effluent Metals and RP Screening Results” table in this attachment This is not a large enough sample size to evaluate the RP for a parameter. As a result, no quantitative RP analysis was performed.
