After passing through the wetlands the effluent discharges directly to the Oil Drain Canal via Outfall 001.003Located at latitude 40o48’47.5” N and longitude 111o55’46.3” W. Primary effluent flows discharging directly to the Oil Drain Canal. Narrative Standard. It shall be unlawful, and a violation of this permit, for the Permittee to discharge or place any waste or other substance in such a way as will be or may become offensive such as unnatural deposits, floating debris, oil, scum, or other nuisances such as color, odor or taste, or cause conditions which produce undesirable aquatic life or which produce objectionable tastes in edible aquatic organisms; or result in concentrations or combinations of substances which produce undesirable physiological responses in desirable resident fish, or other desirable aquatic life, or undesirable human health effects, as determined by a bioassay or other tests performed in accordance with standard procedures. Specific Limitations and Self-Monitoring Requirements.NOTE: As in previous permits, routine monitoring is required at Outfall 003 only. However, a violation of any parameter from Outfall 003 will also be viewed as a violation for the same parameter from Outfall 001. Effective immediately and lasting through the life of this permit, there shall be no acute or chronic toxicity in Outfall 003 as defined in Part VIII, and determined by test procedures described in Part I. C.3.a & b of this permit. Effective immediately and lasting the duration of this permit, the Permittee is authorized to discharge from Outfall 001 & 003.

TUc ≤ 1.6 is applicable when the receiving water effluent concentration is >50%. The TUc is an indicator and an exceedance is not used for determining compliance. Acute/Chronic Whole Effluent Toxicity (WET) Testing. Whole Effluent Testing – Acute Toxicity. Starting on the effective date of this permit, the permittee shall monthly conduct acute static renewal toxicity tests on a composite sample of the final effluent at Outfall 003. The sample shall be collected at the point of compliance before mixing with the receiving water.The monitoring frequency for acute tests shall be monthly unless a sample is found to be acutely toxic during a routine test. If that occurs, the monitoring frequency shall become weekly (See Part 3.c., Accelerated Testing). Unless otherwise approved by the Director, samples shall be collected on a two-day progression; i.e., if the first sample is on a Monday, during the next sampling period, the sampling shall begin on a Wednesday, etc.The static-renewalacute toxicity tests shall be conducted in general accordance with the procedures set out in the latest revision of Methods for Measuring the Acute Toxicity of Effluents and Receiving Waters to Freshwater and Marine Organisms, Fifth Edition, October 2002, EPA-821-R-02-012 as per 40 CFR 136.3(a) TABLE IA-LIST OF APPROVED BIOLOGICAL METHODS. The permittee shall conduct the 48-hour static renewal toxicity test using Ceriodaphnia dubia (solution renewal every 24 hours)and the acute 96-hour static renewal toxicity test using Pimephales promelas (fathead minnow)with alternating the test species monthly and with solution renewal every 24 hours. A carbon dioxide (CO2) atmosphere may be used (in conjunction with an unmodified test) in order to account for artificial pH drift, as previously demonstrated to and authorized by the Director. Based on the Test Acceptability Criteria included in Utah Pollutant Discharge Elimination System (UPDES) Permit and Enforcement Guidance Document for Whole Effluent Toxicity Control (Biomonitoring) February, 2018, the Director may require acceptable variations in the test, i.e. temperature, carbon dioxide atmosphere, or any other acceptable variations in the testing procedure,as documented in the Fact Sheet Statement of Basis. If possible dilution water should be taken from the receiving stream. A valid replacement test is required within the specified sampling period to remain in compliance. Acute toxicity occurs when 50 percent or more mortality is observed for either species at any effluent concentration. Mortality in the control must simultaneously be 10 percent or less for the results to be considered valid. If more than 10 percent control mortalityoccurs, the test shall be repeated until satisfactory control mortality is achieved. The permittee shall meet all QA/QC requirements of the acute WET testing method listed in this Section of the permit. Monthly test results shall be reported along with the DMRsubmitted for the end of the required reporting period. Monthly test results shall be reported along with the DMR submitted for that month. The format for the report shall be consistent with Appendix C of “Utah Pollutant Discharge Elimination System (UPDES) Permitting and Enforcement Guidance Document for Whole Effluent Toxicity (Biomonitoring), Utah Division of Water Quality, February 2018. If the results for ten consecutive tests indicate no acute toxicity, the permittee may request a reduction in acute toxicity testing by a reduction in monitoring frequency, alternating test species, or using only the most sensitive species. The Director may approve or deny the request. If the request is approved, the test procedures are to be the same as specified above for the test species. Under no circumstances shall monitoring for WET at major facilities be reduced less than quarterly. Minor facilities may be less than quarterly at the discretion of the Director.Whole Effluent Testing – Chronic Toxicity. Chronic WET tests are considered an indicator for Class 5 waters (Great Salt Lake) because of uncertainties regarding the representativeness of the standard test species for Great Salt Lake. If a separate acute test is not conducted, the results of the acute duration portion of a chronic test are reported as specified in Part a. Whole Effluent Testing – Acute Toxicity. As an indicator, the chronic test results can demonstrate compliance with portions of the Narrative Standards (R317-2-7.2). However, the chronic WET test results alone do not demonstrate noncompliance with the Narrative Standards. As indicators, the chronic WET test results alone are not used for determining reasonable potential for toxicity or noncompliance with the permit.)Starting on the effective date of this permit, the permittee shall monthly conduct chronic static renewal toxicity tests on a composite sample of the final effluent at Outfall 003. The sample shall be collected at the point of compliance before mixing with the receiving water. Three samples are required and samples shall be collected on Monday, Wednesday and Friday of each sampling period or collected on a two-day progression for each sampling period. This may be changed with Director approval. The chronic toxicity tests shall be conducted in general accordance with the procedures set out in the latest revision of Short-Term Methods for Estimating the Chronic Toxicity of Effluents and Receiving Water to Freshwater Organisms, Fourth Edition, October 2002, EPA—821-R-02-013 as per 40 CFR 136.3(a) TABLE IA-LIST OF APPROVED BIOLOGICAL METHODS. Test species shall consist of Ceriodaphnia dubia and Pimephales promelas (fathead minnow) alternating monthly.A CO2 atmosphere may be used (in conjunction with an unmodified test) in order to account for artificial pH drift, as previously demonstrated to and authorized by the DirectorA multi dilution test consisting of at least five concentrations and a control is required at two dilutions below and two above the RWC, if possible. If test acceptability criteria are not met for control survival, growth, or reproduction, the test shall be considered invalid. A valid replacement test is required within the specified sampling period to remain in compliance with this permit. Chronic toxicity occurs when, during a chronic toxicity test, the 25% inhibition concentration (IC25) calculated on the basis of test organism survival and growth or survival and reproduction, is less than or equal to the full effluent concentration (equivalent to the RWC). If a sample is found to be chronically toxic during a routine test, the monitoring frequency shall become biweekly (see Part 3.c., Accelerated Testing). (the Director may enter acceptable variations in the test procedure here as documented in the Fact Sheet Statement of Basis and based on the test acceptability criteria as contained in Utah Pollutant Discharge Elimination System (UPDES) Permitting and Enforcement Guidance Document for Whole Effluent Toxicity Control February, 2018). If possible, dilution water should be obtained from the receiving stream. Monthlytest results shall be reported along with the DMRsubmitted for the end of the required reporting period. Monthly test results shall be reported along with the DMR submitted for that month. The format for the report shall be consistent with Appendix C of “Utah Pollutant Discharge Elimination System (UPDES) Permitting and Enforcement Guidance Document for Whole Effluent Toxicity, Utah Division of Water Quality, February, 2018. If the results for ten consecutive tests indicate no chronic toxicity, the permittee may submit a request to the Director to allow a reduction in chronic toxicity testing by a reduction in monitoring frequency, alternating test species, or using only the most sensitive species. The permit issuing authority may approve or deny the request based on the results and other available information without public notice. If the request is approved, the test procedures are to be the same as specified above for the test species. Under no circumstances shall monitoring for WET at major facilities be reduced less than quarterly. Minor facilities may be less than quarterly at the discretion of the Director. Accelerated Testing. When whole effluent toxicity is indicated during routine WET testing as specified in this permit, the permittee shall notify the Director in writing within 5 days after becoming aware of the test result. The permittee shall perform an accelerated schedule of WET testing to establish whether a pattern of toxicity exists unless the permittee notifies the Director and commences a PTI, TIE, or a TRE. Accelerated testing or the PTI, TIE, or TRE will begin within fourteen days after the permittee becomes aware of the test result. Accelerated testing shall be conducted as specified under Part I. Pattern of Toxicity. If the accelerated testing demonstrates no pattern of toxicity, routine monitoring shall be resumed. Pattern of Toxicity. A pattern of toxicity is defined by the results of a series of up to five biomonitoring tests pursuant to the accelerated testing requirements using a full set of dilutions for acute (five plus the control) and five effluent dilutions for chronic (five plus the control), on the species found to be more sensitive, once every week for up to five consecutive weeks for acute and once every two weeks up to ten consecutive weeks for chronic. If two (2) consecutive tests (not including the scheduled test which triggered the search for a pattern of toxicity) do not result in an exceedance of the acute or chronic toxicity criteria, no further accelerated testing will be required and no pattern of toxicity will be found to exist. The permittee will provide written verification to the Director within 5 days of determining no pattern of toxicity exists, and resume routine monitoring.A pattern of toxicity may or may not be established based on the following: WET tests should be run at least weekly (acute) or every two weeks (chronic) (note that only one test should be run at a time), for up to 5 tests, until either: 1) 2consecutive tests fail, or 3 out of 5 tests fail, at which point a pattern of toxicity will have been identified, or 2) 2 consecutive tests pass, or 3 out of 5 tests pass, in which case no pattern of toxicity is identified. Preliminary Toxicity Investigation. When a pattern of toxicity is detected the permittee will notify the Director in writing within 5 days and begin an evaluation of the possible causes of the toxicity. The permittee will have 15 working days from demonstration of the pattern of toxicity to complete an optional Preliminary Toxicity Investigation (PTI) and submit a written report of the results to the Director. The PTI may include, but is not limited to: additional chemical and biological monitoring, examination of Pretreatment Program records, examination of discharge monitoring reports, a thorough review of the testing protocol, evaluation of treatment processes and chemical use, inspection of material storage and transfer areas to determine if any spill may have occurred.If the PTI identifies a probable toxicant and/or a probable source of toxicity, the permittee shall submit, as part of its final results, written notification of that effect to the Director. Within thirty days of completing the PTI the permittee shall submit to the Director for approval a control program to control effluent toxicity and shall proceed to implement such plan in accordance with the Director’s approval. The control program, as submitted to or revised by the Director, will be incorporated into the permit. After final implementation, the permittee must demonstrate successful removal of toxicity by passing a two species WET test as outlined in this permit. With adequate justification, the Director may extend these deadlines.If no probable explanation for toxicity is identified in the PTI, the permittee shall notify the Director as part of its final report, along with a schedule for conducting a Phase I Toxicity Reduction Evaluation (TRE) (see Part ___ Toxicity Reduction EvaluationIf toxicity spontaneously disappears during the PTI, the permittee shall submit written notification to that effect to the Director, with supporting testing evidence. Toxicity Reduction Evaluation (TRE). If a pattern of toxicity is detected the permittee shall initiate a TIE/TRE within 7 days unless the Director has accepted the decision to complete a PTI. With adequate justification, the Director may extend the 7-day deadline. The purpose of the TIE portion of a TRE will be to establish the cause of the toxicity, locate the source(s) of the toxicity, and the TRE will control or provide treatment for the toxicity. A TRE may include but is not limited to one, all, or a combination of the following: Phase I – Toxicity Characterization Phase II – Toxicity Identification Procedures Phase III – Toxicity Control Procedures Any other appropriate procedures for toxicity source elimination and control. If the TRE establishes that the toxicity cannot be immediately eliminated, the permittee shall submit a proposed compliance plan to the Director. The plan shall include the proposed approach to control toxicity and a proposed compliance schedule for achieving control. If the approach and schedule are acceptable to the Director, this permit may be reopened and modified.If toxicity spontaneously disappears during the TIE/TRE, the permittee shall submit written notification to that effect to the Director. If the TRE shows that the toxicity is caused by a toxicant(s) that may be controlled with specific numerical limitations, the permittee shall submit the following: An alternative control program for compliance with the numerical requirements. If necessary, as determined by the Director, provide a modified biomonitoring protocol which compensates for the pollutant(s) being controlled numerically. This permit may be reopened and modified to incorporate any additional numerical limitations, a modified compliance schedule if judged necessary by the Director, and/or modified WET testing requirements without public notice. Failure to conduct an adequate TIE/TRE plan or program as described above, or the submittal of a plan or program judged inadequate by the Director, shall be considered a violation of this permit. After implementation of TIE/TRE plan, the permittee must demonstrate successful removal of toxicity by passing a two species WET test as outlined in this permit. Reporting of Monitoring Results. Reporting of Wastewater Monitoring ResultsMonitoring results obtained during the previous month shall be summarized for each month and reported on a Discharge Monitoring Report Form (EPA No. 3320-1)or by NetDMR, post-marked or entered into NetDMR no later than the 28th day of the month following the completed reporting period. If no discharge occurs during the reporting period, “no discharge” shall be reported. Legible copies of these, and all other reports including whole effluent toxicity (WET) test reports required herein, shall be signed and certified in accordance with the requirements of Signatory Requirements (see Part VII.G), and submitted by NetDMR, or to the Division of Water Quality at the following address:Department of Environmental QualityDivision of Water QualityPO Box 144870Salt Lake City, Utah 84114-4870PRETREATMENT REQUIREMENTSPretreatment Program Delegation.

Such modifications shall be completed within the time frame set forth by the applicable regulations. Modification of the Approved POTW Pretreatment Program must be done in accordance with the requirements of 40 CFR Part 403.18. Modifications of the approved program which result in less stringent Industrial User requirements shall not be effective until after approval has been granted by the Director.Annual Report. The Permittee shall provide the Division of Water Quality and EPA with an annual report briefly describing the Pretreatment Program activities over the previous calendar year for the Permittee. Reports shall be submitted no later than March 28 of each year. ThePermittee shall submit an annual report, that includes at a minimum, the following: An updated listing of the Industrial Users.A descriptive summary of the compliance activities including numbers of any major enforcement actions, i.e., administrative orders, penalties, civil actions, etc.An assessment of the compliance status of the Industrial Users and the effectiveness of the Pretreatment Program in meeting its needs and objectives.A description of all changes made to the Pretreatment Program. Changes to pollutants of concern to include but not limited to the followingViolations of effluent limits,Summary of pollutants of concern, andExceedances of the maximum headwork loading or industrial loading.Other information as may be determined necessary by the Director.General and Specific Prohibitions. Pretreatment standards (40 CFR 403.5) specifically prohibit the introduction of the following pollutants into the waste treatment system from any source of non-domestic discharge:Pollutants which create a fire or explosion hazard in the publicly owned treatment works (POTW), including, but not limited to, wastestreams with a closed cup flashpoint of less than 140˚F (60˚C);Pollutants, which will cause corrosive structural damage to the POTW, but in no case, discharges with a pH lower than 5.0;Solid or viscous pollutants in amounts which will cause obstruction to the flow in the POTW resulting in Interference;Any pollutant, including oxygen demanding pollutants (BOD, etc.), released in a discharge at such volume or strength as to cause Interference in the POTW;Heat in amounts, which will inhibit biological activity in the POTW, resulting in Interference, but in no case, heat in such quantities that the influent to the sewage treatment works exceeds 104˚F (40˚C)); Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin in amounts that will cause Interference or Pass Through;Pollutants, which result in the presence of toxic gases, vapor, or fumes within the POTW in a quantity that may cause worker health or safety problems;Any trucked or hauled pollutants, except at discharge points designated by the POTW; orAny pollutant that causes Pass Through or Interference at the POTW.Any specific pollutant which exceeds any Local Limit established by the POTW in accordance with the requirement of 40 CFR Parts 403.5(c) and 403.5(d).Categorical Standards. In addition to the general and specific limitations expressed in Part D of this section, applicable National Categorical Pretreatment Standards must be met by all Industrial Users of the POTW. These standards are published in the federal regulations at 40 CFR 405 et. seq.Self-Monitoring and Reporting Requirements.Influent and Effluent Monitoring and Reporting Requirements. The Permittee shall sample and analyze both the influent and effluent, for the parameters listed in the Monitoring for Pretreatment Program Table.Monitoring for Pretreatment Program TableParameterReporting LimitSample TypeFrequencyUnitsTotal Arsenic2.27CompositeOnce every two monthsmg/LTotal Cadmium0.0454Total Chromium0.153Total Copper0.552Total Lead0.383Total MolybdenumNATotal Nickel3.73Total Selenium0.0693Total Silver0.472Total Zinc4.34Total Cyanide0.117Composite/GrabTotal Mercury0.000272TTOsNATwice YearlyA test method must be used that has areporting limitas stated in the column. If a test method is not available the Permittee must submit documentation to the Director regarding the method that will be used.The influent and effluent shall be analyzed by the Permittee for total toxic pollutants (TTOs) listed in 40 CFR Part 122 Appendix D Table II (Organic Toxic Pollutants). The pesticides fraction of Appendix D, Table II is suspended unless pesticides are expected to be present.The results of the analyses of metals, cyanide and toxic organics shall be submitted along with the DMR at the end of the earliest possible reporting period. Also, the Permittee must submit a copy of the toxic organics data to the Pretreatment Coordinator forDWQ via email. In accordance with the requirements of 40 CFR Part 403.5(c), the Permittee shall determine if there is a need to develop or revise its Local Limits in order to implement the general and specific prohibitions of 40 CFR Part 403.5 (a) and Part 403.5 (b). A technical evaluation of the need to develop or revise Local Limits shall be submitted to the Division within 12 months of the effective date of this permit. This evaluation should be conducted in accordance with the latest revision of the EPA Local Limits Development Guidance. If a technical evaluation, reveals that development or revision of Local Limits is necessary, the Permittee shall submit the proposed Local Limits revision to the Division of Water Quality for approval, and after approval implement the new Local Limits, within 12 months of the determination that a revision is necessary.For Local Limit parameters it is recommended that the most sensitive method be used for analysis. This will determine if the parameter is present and provide removal efficiencies based on actual data rather than literature values. If a parameter load is greater than the allowable head works load, for any pollutant listed in Part II.K.1. or Part I, or a pollutant of concern listed in the Local Limit development document, the Permittee must report the information to the Pretreatment Coordinator for theDWQ. If the loading exceeds the allowable headworks load, increase sampling must occur based on the requirements given by the Pretreatment Coordinator for theDWQ. If needed sampling may need to occur to find the source(s) of the increase. This may include sampling of the collection system and/or additional sampling of Industrial Users. Notification regarding the exceedances of the allowable headworks loading can be provided via email.Enforcement Notice. Section19-5-104 of the Act provides that the State may issue a notice to the POTW stating that a determination has been made that appropriate enforcement action must be taken against an Industrial User for noncompliance with any pretreatment requirements within 30 days. The issuance of such notice shall not be construed to limit the authority of the Director.Formal Action. The Director retains the right to take legal action against any Industrial User and/or POTW for those cases where a permit violation has occurred because of the failure of an Industrial User to meet an applicable pretreatment standard. BIOSOLIDS REQUIREMENTS Biosolids Treatment and Disposal. The authorization to dispose of biosolids provided under this permit is limited to those biosolids produced from the treatment works owned and operated by the Permittee. The treatment methods and disposal practices are designated below. Treatment Anaerobic Digestion - Under 40 CFR 503.32(b)(3) Appendix (B)(3) The PSRP may be accomplished through anaerobic digesters that have a minimum retention time of 15 days at 95° F (35° C) or 60 days at 68° F (20°C), and/or Air Drying - Under 40 CFR 503.32 (b)(3), Appendix B.2. The PSRP may be accomplished through air drying. The biosolids are applied to an impervious surface and dried at a depth of no more than 9 inches (23 cm) deep. The biosolids are allowed to dry for a minimum of 3 months. During 2 of the 3 months, the ambient average daily temperature is above 32o F (0o C). Description of Biosolids Disposal Method Class A biosolids may be sold or given away to the public for lawn and garden use or land application. Class B biosolids may be land applied for agriculture use or at reclamation sites at agronomic rates. Biosolids may be disposed of in a landfill or transferred to another facility for treatment and/or disposal. Changes in Treatment Systems and Disposal Practices. Should the Permittee change their disposal methods or the biosolids generation and handling processes of the plant, the Permittee must notify the Director at least 30 days in advance if the process/method is specified in 40 CFR Part 503. This includes, but is not limited to, the permanent addition or removal of any biosolids treatment units (i.e., digesters, drying beds, belt presses, etc.) and/or any other change. Should the Permittee change their disposal methods or the biosolids generation and handling processes of the plant, the Permittee must notify the Director at least 180 days in advance if the process/method is not specified in 40 CFR Part 503. This includes, but is not limited to, the permanent addition or removal of any biosolids treatment units (i.e., digesters, drying beds, belt presses, etc.) and/or any other change.For any biosolids that are land filled, the Permittee shall follow the requirements in Section 2.12 of the latest version of the EPA Region VIII Biosolids Management Handbook must be followed Specific Limitations and Monitoring Requirements.All biosolids generated by this facility to be sold or given away to the public shall meet the requirements of Part III.B.1, 2, 3 and 4 listed below.

The permitted facility will meet vector attraction reduction through use of one of the methods listed in 40 CFR Part 503.33. Facility is meeting the requirements though the following methods. SLCWRF is meeting vector attraction reduction under 40 CFR 503.33(b)(1), the solids need to be treated through anaerobic digestion for at least 15 days at a temperature of a least 35° C (95° F) with a 38% reduction of volatile solids. SLCWRF is meeting vector attraction reduction under 40 CFR 503.33(b)(11), the solids are transferred to another facility (E.T. Technologies) where they incorporated into soil treatment cells daily and are stabilized and use as cover on the Salt Lake County Landfill. SLCWRF will meet vector attraction reduction under 40 CFR 503.33(b)(10), the land applied solids will be incorporated into the soils at the end of the operating day. If the Permittee intends to use another one of the alternatives, the Director and the EPA must be informed at least thirty (30) days prior to its use. Self-Monitoring Requirements. At a minimum, upon the effective date of this permit, all chemical pollutants, pathogens and applicable vector attraction reduction requirements shall be monitored according to 40 CFR Part 503.16(1)(a). Minimum Frequency of Monitoring (40 CFR Part 503.16, 503.26. and 503.46) Amount of Biosolids Disposed 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 Facility produced 3,492 Dry Metric Tons in 2022. Accordingly, they will sample at least 6 times per year Sample collection, preservation and analysis shall be performed in a manner consistent with the requirements of 40 CRF 503 and/or other criteria specific to this permit. A metals analysis is to be performed using Method SW 846 with Method 3050 used for digestion. For the digestion procedure, an amount of biosolids equivalent to a dry weight of one gram shall be used. The methods are also described in the latest version of the Region VIII Biosolids Management Handbook. The Director may request additional monitoring for specific pollutants derived from biosolids if the data shows a potential for concern. After two (2) years of monitoring at the frequency specified, the Permittee may request that the Director reduce the sampling frequency for the heavy metals. The frequency cannot be reduced to less than once per year for biosolids that are sold or given away to the public for any parameter. The frequency also cannot be reduced for any of the pathogen or vector attraction reduction requirements listed in this permit. Management Practices of Biosolids. Biosolids Distribution Information For biosolids that are sold or given away, an information sheet shall be provided to the person who receives the biosolids. The label or information sheet shall contain: The name and address of the person who prepared the biosolids for a sale or to be given away. A statement that prohibits the application of the biosolids to the land except in accordance with the instructions on the label or information sheet. Biosolids Application Site Storage For biosolids or material derived from biosolids that are stored in piles for one year or longer, measures shall be taken to ensure that erosion (whether by wind or water) does not occur. However, best management practices should also be used for piles used for biosolids treatment. If a treatment pile is considered to have caused a problem, best management practices could be added as a requirement in the next permit renewal Land Application Practices The permittee shall operate and maintain the land application site operations in accordance with the following requirements: The permittee shall provide to the Director and the EPA within 90 days of the effective date of this permit a land application plan. Application of biosolids shall be conducted in a manner that will not contaminate the groundwater or impair the use classification for that water underlying the sites. Application of biosolids shall be conducted in a manner that will not cause a violation of any receiving water quality standard from discharges of surface runoff from the land application sites. Biosolids shall not be applied to land 10 meters or less from waters of the United States (as defined in 40 CFR 122.2). No person shall apply biosolids for beneficial use to frozen, ice-covered, or snow-covered land where the slope of such land is greater than three percent and is less than or equal to six percent unless one of the following requirements is met: there is 80 percent vegetative ground cover; or, approval has been obtained based upon a plan demonstrating adequate runoff containment measures. Application of biosolids is prohibited to frozen, ice-covered, or snow-covered sites where the slope of the site exceeds six percent. Agronomic Rate Application of biosolids shall be conducted in a manner that does not exceed the agronomic rate for available nitrogen of the crops grown on the site. At a minimum, the permittee is required to follow the methods for calculating agronomic rate outlined in the latest version of the Region VIII Biosolids Management Handbook (other methods may be approved by the Director). The treatment plant shall provide written notification to the applier of the biosolids of the concentration of total nitrogen (as N on a dry weight basis) in the biosolids. Written permission from the Director is required to exceed the agronomic rate. The permittee may request the limits of Part III.C.6. be modified if different limits would be justified based on local conditions. The limits are required to be developed in cooperation with the local agricultural extension office or university. Deep soil monitoring for nitrate-nitrogen is required for all land application sites (does not apply to sites where biosolids are applied less than once every five years). A minimum of six samples for each 320 (or less) acre area is to be collected. These samples are to be collected down to either a 5-foot depth, or the confining layer, whichever is shallower (sample at 1 foot, 2 foot, 3 foot, 4 foot and 5 foot intervals). Each of these one-foot interval samples shall be analyzed for nitrate-nitrogen. In addition to the one-foot interval samples, a composite sample of the 5-foot intervals shall be taken, and analyzed for nitrate-nitrogen as well. Samples are required to be taken once every five years for non-irrigated sites that receive more than 18 inches of precipitation annually or for irrigated sites Biosolids shall not be applied to any site area with standing surface water. If the annual high groundwater level is known or suspected to be within five feet of the surface, additional deep soil monitoring for nitrate-nitrogen as described in Part III.C.(6)(c). is to be performed. At a minimum, this additional monitoring will involve a collection of more samples in the affected area and possibly more frequent sampling. The exact number of samples to be collected will be outlined in a deep soil monitoring plan to be submitted to the Director and the EPA within 90 days of the effective date of this permit. The plan is subject to approval by the Director. The specified cover crop shall be planted during the next available planting season. If this does not occur, the permittee shall notify the Director in writing. Additional restrictions may be placed on the application of the biosolids on that site on a case-by-case basis to control nitrate movement. Deep soil monitoring may be increased under the discretion of the Director. When weather and or soil conditions prevent adherence to the biosolids application procedure, biosolids shall not be applied on the site. For biosolids that are sold or given away, an information sheet shall be provided to the person who receives the biosolids. The label or information sheet shall contain: The name and address of the person who prepared the biosolids for sale or give away for application to the land. A statement that prohibits the application of the biosolids to the land except in accordance with the instructions on the label or information sheet. The annual whole biosolids application rate for the biosolids that do not cause the metals loading rates in Tables 1, 2, and 3 (Part III.B.1.) to be exceeded. Biosolids subject to the cumulative pollutant loading rates in Table 2 (Part III.B.1.) shall not be applied to agricultural land, forest, a public contact site, or a reclamation site if any of the cumulative pollutant loading rates in Table 2 have been reached. If the treatment plant applies the biosolids, it shall provide the owner or leaseholder of the land on which the biosolids are applied notice and necessary information to comply with the requirements in this permit. The permittee shall inspect the application of the biosolids to active sites to prevent malfunctions and deterioration, operator errors and discharges, which may cause or lead to the release of biosolids to the environment or a threat to human health. The permittee must conduct these inspections often enough to identify problems in time to correct them before they harm human health or the environment. The permittee shall keep an inspection log or summary including at least the date and time of inspection, the printed name and the handwritten signature of the inspector, a notation of observations made and the date and nature of any repairs or corrective action. Special Conditions on Biosolids Storage. Permanent storage of biosolids is prohibited. Biosolids shall not be temporarily stored for more than two (2) years. Written permission to store biosolids for more than two years must be obtained from the Director. Storage of biosolids for more than two years will be allowed only if it is determined that significant treatment is occurring. Representative Sampling. Biosolids samples used to measure compliance with Part III of this Permit shall be collected at locations representative of the quality of biosolids generated at the treatment works and immediately prior to land application. Reporting of Monitoring Results. Biosolids. The Permittee shall provide the results of all monitoring performed in accordance with Part III.B, and information on management practices, biosolids treatment, site restrictions and certifications shall be provided no later than February 19 of each year. Each report is for the previous calendar year. If no biosolids were sold or given away during the reporting period, "no biosolids were sold or given away" shall be reported. Legible copies of these, and all other reports required herein, shall be signed and certified in accordance with the Signatory Requirements (see Part VII.G), and submitted to the Utah Division of Water Quality and the EPA by the NeT-Biosolids system through the EPA Central Data Exchange (CDX) System.

COMPLIANCE RESPONSIBILITIES Duty to Comply. The Permittee must comply with all conditions of this permit. Any permit noncompliance constitutes a violation of the Act and is grounds for enforcement action; for permit termination, revocation and reissuance, or modification; or for denial of a permit renewal application. The Permittee shall give advance notice to the Director of any planned changes in the permitted facility or activity, which may result in noncompliance with permit requirements. Penalties for Violations of Permit Conditions. The Act provides that any person who violates a permit condition implementing provisions of the Act is subject to a civil penalty not to exceed $10,000 per day of such violation. Except as provided at Part VI.G, Bypass of Treatment Facilities and Part VI.H, Upset Conditions, nothing in this permit shall be construed to relieve the permittee of the civil or criminal penalties for noncompliance. Need to Halt or Reduce Activity not a Defense. It shall not be a defense for a permittee in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of this permit. Duty to Mitigate. The Permittee shall take all reasonable steps to minimize or prevent any discharge in violation of this permit, which has a reasonable likelihood of adversely affecting human health or the environment. The permittee shall also take all reasonable steps to minimize or prevent any land application in violation of this permit. Proper Operation and Maintenance. The Permittee shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the permittee to achieve compliance with the conditions of this permit. Proper operation and maintenance also includes adequate laboratory controls and quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems, which are installed by a permittee only when the operation is necessary to achieve compliance with the conditions of the permit. Removed Substances. Collected screening, grit, solids, sludge, or other pollutants removed in the course of treatment shall be disposed of in such a manner so as to prevent any pollutant from entering any waters of the state or creating a health hazard. Sludge/digester supernatant and filter backwash shall not directly enter either the final effluent or waters of the state by any other direct route. Bypass of Treatment Facilities. Bypass Not Exceeding Limitations. The Permittee may allow any bypass to occur which does not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to paragraph 2and 3 of this section. Prohibition of Bypass. Bypass is prohibited, and the Director may take enforcement action against a permittee for bypass, unless: Bypass was unavoidable to prevent loss of human life, personal injury, or severe property damage; There were no feasible alternatives to bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate backup equipment should have been installed in the exercise of reasonable engineering judgement to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance, and The Permittee submitted notices as required under PartVI.G.3. The Director may approve an anticipated bypass, after considering its adverse effects, if the Director determines that it will meet the three conditions listed in Parts VI.G.2.a (1), (2) and (3). Notice. Anticipated bypass. Except as provided above in Part VI.G.2and below in PartVI.G.3.b, if the permittee knows in advance of the need for a bypass, it shall submit prior notice, at least ninety days before the date of bypass. The prior notice shall include the following unless otherwise waived by the Director: Evaluation of alternative to bypass, including cost-benefit analysis containing an assessment of anticipated resource damages: A specific bypass plan describing the work to be performed including scheduled dates and times. The permittee must notify the Director in advance of any changes to the bypass schedule; Description of specific measures to be taken to minimize environmental and public health impacts; A notification plan sufficient to alert all downstream users, the public and others reasonably expected to be impacted by the bypass; A water quality assessment plan to include sufficient monitoring of the receiving water before, during and following the bypass to enable evaluation of public health risks and environmental impacts; and, Any additional information requested by the Director. Emergency Bypass. Where ninety days advance notice is not possible, the permittee must notify the Director, and the Director of the Department of Natural Resources, as soon as it becomes aware of the need to bypass and provide to the Director the information in Part VI.G.3.a.(1) through (6) to the extent practicable. Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass to the Director as required under Part IV.H, Twenty-Four Hour Reporting. The permittee shall also immediately notify the Director of the Department of Natural Resources, the public and downstream users and shall implement measures to minimize impacts to public health and environment to the extent practicable. Upset Conditions. Effect of an upset. An upset constitutes an affirmative defense to an action brought for noncompliance with technology-based permit effluent limitations if the requirements of paragraph 2 of this section are met. Director's administrative determination regarding a claim of upset cannot be judiciously challenged by the permittee until such time as an action is initiated for noncompliance. Conditions necessary for a demonstration of upset. A permittee who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that: An upset occurred and that the permittee can identify the cause(s) of the upset; The permitted facility was at the time being properly operated; The permittee submitted notice of the upset as required under Part V.H, Twenty-four Hour Notice of Noncompliance Reporting; and, The permittee complied with any remedial measures required under Part VI.D, Duty to Mitigate. Burden of proof. In any enforcement proceeding, the permittee seeking to establish the occurrence of an upset has the burden of proof. GENERAL REQUIREMENTS Planned Changes. The permittee shall give notice to the Director as soon as possible of any planned physical alterations or additions to the permitted facility. Notice is required only when: The alteration or addition to a permitted facility may meet one of the criteria for determining whether a facility is a new source in 122.29(b); or The alteration or addition could significantly change the nature or increase the quantity of pollutants discharged. This notification applies to pollutants which are subject neither to effluent limitations in the permit nor to notification requirements under Subsection R317-8-4.1(15). The alteration or addition results in a significant change in the permittee's sludge use or disposal practices, and such alteration, addition, or change may justify the application of permit conditions that are different from or absent in the existing permit, including notification of additional use or disposal sites not reported during the permit application process or not reported pursuant to an approved land application plan.The permittee shall give notice to the Director of any planned changes at least 30 days prior to their implementation. Anticipated Noncompliance. The permittee shall give advance notice to the Director of any planned changes in the permitted facility or activity, which may result in noncompliance with permit requirements. Permit Actions. This permit may be modified, revoked and reissued, or terminated for cause. The filing of a request by the permittee for a permit modification, revocation and reissuance, or termination, or a notification of planned changes or anticipated noncompliance, does not stay any permit condition. Duty to Reapply. If the permittee wishes to continue an activity regulated by this permit after the expiration date of this permit, the permittee shall apply for and obtain a new permit. The application shall be submitted at least 180 days before the expiration date of this permit. Duty to Provide Information. The permittee shall furnish to the Director, within a reasonable time, any information which the Director may request to determine whether cause exists for modifying, revoking and reissuing, or terminating this permit, or to determine compliance with this permit. The permittee shall also furnish to the Director, upon request, copies of records required to be kept by this permit. Other Information. When the permittee becomes aware that it failed to submit any relevant facts in a permit application, or submitted incorrect information in a permit application or any report to the Director, it shall promptly submit such facts or information. Signatory Requirements. All applications, reports or information submitted to the Director shall be signed and certified. All permit applications shall be signed by either a principal executive officer or ranking elected official.A person is a duly authorized representative only if: The authorization is made in writing by a person described above and submitted to the Director, and, The authorization specifies either an individual or a position having responsibility for the overall operation of the regulated facility, such as the position of plant manager, superintendent, position of equivalent responsibility, or an individual or position having overall responsibility for environmental matters.

Water Quality - Reopener Provision. This permit may be reopened and modified (following proper administrative procedures) to include the appropriate effluent limitations and compliance schedule, if necessary, if one or more of the following events occurs: Water Quality Standards for the receiving water(s) to which the permittee discharges are modified in such a manner as to require different effluent limits than contained in this permit. A final wasteload allocation is developed and approved by the State and/or EPA for incorporation in this permit. Revisions to the current CWA § 208 areawide treatment management plans or promulgations/revisions to TMDLs (40 CFR 130.7) approved by the EPA and adopted by DWQ which calls for different effluent limitations than contained in this permit. Biosolids – Reopener Provision. This permit may be reopened and modified (following proper administrative procedures) to include the appropriate biosolids limitations (and compliance schedule, if necessary), management practices, other appropriate requirements to protect public health and the environment, or if there have been substantial changes (or such changes are planned) in biosolids use or disposal practices; applicable management practices or numerical limitations for pollutants in biosolids have been promulgated which are more stringent than the requirements in this permit; and/or it has been determined that the permittees biosolids use or land application practices do not comply with existing applicable state of federal regulations. Toxicity Limitation - Reopener Provision. Use the following paragraph if WET testing is required at the facility:This permit may be reopened and modified (following proper administrative procedures) to include, whole effluent toxicity (WET) limitations, a compliance date, a compliance schedule, a change in the whole effluent toxicity (biomonitoring) protocol, additional or modified numerical limitations, or any other conditions related to the control of toxicants if one or more of the following events occur; Toxicity is detected, as per Part I.C.3.a and/orbof this permit, during the duration of this permit. The TRE results indicate that the toxicant(s) represent pollutant(s) or pollutant parameter(s) that may be controlled with specific numerical limits, and the Director concludes that numerical controls are appropriate. Following the implementation of numerical control(s) of toxicant(s), the Director agrees that a modified biomonitoring protocol is necessary to compensate for those toxicants that are controlled numerically. The TRE reveals other unique conditions or characteristics, which in the opinion of the permit issuing authority justify the incorporation of unanticipated special conditions in the permit. DEFINITIONSWastewater. The “7-day (and weekly) average”, other than for E. coli bacteria, fecal coliform bacteria, and total coliform bacteria, is the arithmetic average of all samples collected during a consecutive 7-day period or calendar week, whichever is applicable. Geometric means shall be calculated for E. coli bacteria, fecal coliform bacteria, and total coliform bacteria. The 7-day and weekly averages are applicable only to those effluent characteristics for which there are 7-day average effluent limitations. The calendar week, which begins on Sunday and ends on Saturday, shall be used for purposes of reporting self-monitoring data on discharge monitoring report forms. Weekly averages shall be calculated for all calendar weeks with Saturdays in the month. If a calendar week overlaps two months (i.e., the Sunday is in one month and the Saturday in the following month), the weekly average calculated for that calendar week shall be included in the data for the month that contains Saturday. The "30-day (and monthly) average," other than for E. coli bacteria, fecal coliform bacteria and total coliform bacteria, is the arithmetic average of all samples collected during a consecutive 30-day period or calendar month, whichever is applicable. Geometric means shall be calculated for E. coli bacteria, fecal coliform bacteria and total coliform bacteria. The calendar month shall be used for purposes of reporting self-monitoring data on discharge monitoring report forms. "Average annual discharge limit" means maximum allowable average of monthly discharges over a calendar year, calculated as the sum of all monthly discharges measured during a calendar year divided by the number of monthly discharges measured during the year. The timeframe is defined as from January 1st to December 31st. “Act,” means the Utah Water Quality Act. “Acute toxicity” occurs when 50 percent or more mortality is observed for either test species at any effluent concentration (lethal concentration or “LC50”). “Bypass,” means the diversion of waste streams from any portion of a treatment facility. “Chronic toxicity” occurs when during a chronic test, the 25% inhibition concentration (IC25) calculated on the basis of test organism survival and growth, or survival and reproduction, is less than or equal to the effluent dilution designated as the receiving water concentration (RWC). "IC25" is the concentration of toxicant (given in % effluent) that would cause a 25% reduction in mean young per female, or a 25% reduction in overall growth for the test population. “Composite Samples” shall be flow proportioned. The composite sample shall, as a minimum, contain at least four (4) samples collected over the compositing period. Unless otherwise specified, the time between the collection of the first sample and the last sample shall not be less than six (6) hours nor more than 24 hours. Acceptable methods for preparation of composite samples are as follows: Constant time interval between samples, sample volume proportional to flow rate at time of sampling; Constant time interval between samples, sample volume proportional to total flow (volume) since last sample. For the first sample, the flow rate at the time the sample was collected may be used; Constant sample volume, time interval between samples proportional to flow (i.e., sample taken every “X” gallons of flow); and, Continuous sample volume, with sample collection rate proportional to flow rate. “CWA”means The Federal Water Pollution Control Act, as amended, by The Clean Water Act of 1987. “Daily Maximum” (Daily Max.) is the maximum value allowable in any single sample or instantaneous measurement. “EPA,” means the United States Environmental Protection Agency. “Director,” means Director of the Division of Water Quality. A “grab” sample, for monitoring requirements, is defined as a single “dip and take” sample collected at a representative point in the discharge stream. An “instantaneous” measurement, for monitoring requirements, is defined as a single reading, observation, or measurement. “Severe Property Damage,” means substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production. “Upset,” means an exceptional incident in which there is unintentional and temporary noncompliance with technology-based permit effluent limitations because of factors beyond the reasonable control of the permittee. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventative maintenance, or careless or improper operation. Biosolids. “Biosolids,” means any material or material derived from sewage solids that have been biologically treated. “Dry Weight-Basis,” means 100 percent solids (i.e. zero percent moisture). “Land Application” is the spraying or spreading of biosolids onto the land surface; the injection of biosolids below the land surface; or the incorporation of biosolids into the land so that the biosolids can either condition the soil or fertilize crops or vegetation grown in the soil. Land application includes distribution and marketing (i.e. the selling or giving away of the biosolids). “Pathogen,” means an organism that is capable of producing an infection or disease in a susceptible host. “Pollutant” for the purposes of this permit is an organic substance, an inorganic substance, a combination of organic and inorganic substances, or pathogenic organisms that after discharge and upon exposure, ingestion, inhalation, or assimilation into an organism either directly from the environment or indirectly by ingestion through the food-chain, could on the basis of information available to the Administrator of EPA, cause death, disease, behavioral abnormalities, cancer, genetic mutations, physiological malfunctions (including malfunction in reproduction), or physical deformations in either organisms or offspring of the organisms. “Runoff” is rainwater, leachate, or other liquid that drains over any part of a land surface and runs off the land surface. “Similar Container” is either an open or closed receptacle. This includes, but is not limited to, a bucket, a box, a carton, and a vehicle or trailer with a load capacity of one metric ton or less. “Total Solids” are the materials in the biosolids that remain as a residue if the biosolids are dried at 103o or 105o Celsius. “Treatment Works” are either Federally owned, publicly owned, or privately owned devices or systems used to treat (including recycling and reclamation) either domestic sewage or a combination of domestic sewage and industrial waste or liquid manure. “Vector Attraction” is the characteristic of biosolids that attracts rodents, flies mosquito’s or other organisms capable of transporting infectious agents. “Animals” for the purpose of this permit are domestic livestock. “Annual Whole Sludge Application Rate” is the amount of sewage sludge (dry-weight basis) that can be applied to a unit area of land during a cropping cycle. “Agronomic Rate is the whole sludge application rate (dry-weight basis) designed to: (1) provide the amount of nitrogen needed by the crop or vegetation grown on the land; and (2) minimize the amount of nitrogen in the sewage sludge that passes below the root zone of the crop or vegetation grown on the land to the ground water. “Annual Pollutant Loading Rate” is the maximum amount of a pollutant (dry-weight basis) that can be applied to a unit area of land during a 365-day period. “Application Site or Land Application Site” means all contiguous areas of a users’ property intended for sludge application. “Cumulative Pollutant Loading Rate” is the maximum amount of an inorganic pollutant (dry-weight basis) that can be applied to a unit area of land. “Grit and Screenings” are sand, gravel, cinders, other materials with a high specific gravity and relatively large materials such as rags generated during preliminary treatment of domestic sewage at a treatment works and shall be disposed of according to 40 CFR 258. “High Potential for Public Contact Site” is land with a high potential for contact by the public. This includes, but is not limited to, public parks, ball fields, cemeteries, plant nurseries, turf farms, and golf courses. “Low Potential for Public Contact Site” is the land with a low potential for contact by the public.
