Flow measurements of influent/effluent volume shall be made in such a manner that the Permittee can affirmatively demonstrate that representative values are being obtained.
If the rate of discharge is controlled, the rate and duration of discharge shall be reported.
In addition to monitoring the final discharge, influent samples shall be taken and analyzed for this constituent at the same frequency as required for this constituent in the discharge.
Oil & Grease sampled when sheen is present or visible. If no sheen is present or visible, report a no data indicator (NODI) code of 9 (Conditional Monitoring -Not Required This Period)
These reflect changes required with the adoption of UCA R317-1-3.3, Technology-based Phosphorus Effluent Limits rule.
Total phosphorus isalso being sampled in support of the work being done for the work TMDL currently underway for the Bear River from Great Salt Lake to Malad River. The Pollutants Of
Concern (POC) will be monitored and reported (on a monthly basis by the facility on Discharge Monitoring Report, but will not have a limit associated with them /or at the end of each
Calendar year of sampling for these POC’s), (Permittee) will report the results of all sampling done for the POC. If (Permittee) decides to sample more frequently for these POC’s, the
additional data will be welcome
Tremonton will be required to have the effluent analyzed for mercury using a method that is sensitive enough to demonstrate a presence or absence of mercury in the effluent, such as
EPA Method 245.7 or 1631.
See table below for the list of metals that must be included in the metals monitoring.
See Part II of the permit for additional requirements regarding sampling for metals and organic toxics.
All metals other than mercury and selenium are only required to be monitored for twice per year. As a result of the RP analysis, mercury and selenium must be sampled at least quarterly.
A list of the organics to be tested can be found in 40CFR122 appendix D table II.
Compliance Schedule.
There is no Compliance Schedule included in this renewal permit.
Acute/Chronic Whole Effluent Toxicity (WET) Testing.
Whole Effluent Testing – Acute Toxicity. Starting on<<Month Day, Year>>,the permittee shall quarterly conduct acute static renewal toxicity tests on a composite sample of the final
effluent at Outfall 001. The sample shall be collected at the point of compliance before mixing with the receiving water.The monitoring frequency for acute tests shall be quarterly
unless a sample is found to be acutely toxic during a routine test. If that occurs, the monitoring frequency shall become weekly (See Part I.C.3.b, 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)(solution renewal every 24 hours). This will be done alternating quarterly between Ceriodaphniadubiaand Pimephalespromelas (fathead minnow).
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. If the permit contains a total residual chlorine limitation such that it may
interfere with WET testing (>0.20 mg/L), the permittee may dechlorinate the sample in accordance with approved USEPA methods for WET testing the sample. If dechlorination is affecting
the test, the permittee may collect the sample just before chlorination with Director approval. Quarterly test results shall be reported along with the Discharge Monitoring Report (DMR)
submitted for the end of the required reporting period (month, quarter or semi-annual) e.g., biomonitoring results for the calendar quarter ending March 31 shall be reported with the
DMR due April 28, with the remaining biomonitoring reports submitted with DMRs due each July 28, October 28, and January 28. 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. Whole Effluent Testing – Chronic Toxicity. As part of the nationwide effort to control
toxics, biomonitoring requirements are being included in all major permits and in minor permits for facilities where effluent toxicity is an existing or potential concern. Authorization
for requiring effluent biomonitoring is provided for in UAC R317-8-4.2 and R317-8-5.3. The Permitting and Enforcement Guidance Document for Whole Effluent Toxicity (Biomonitoring), Utah
Division of Water Quality, February 2018, outlines guidance to be used by Utah Division of Water Quality staff and by permittee’s for implementation of WET control through the UPDES
discharge permit program. The requirement to monitor for whole effluent toxicity (WET) Chronic Toxicity has not been included in this permit. This permit may be reopened and modified
(following proper administrative procedures) to include, WET limitations, a compliance date, a compliance schedule, a change in the WET protocol, additional or modified numerical limitations,
or any other conditions related to the control of toxicants in accordance with Part VII, Q of this permit. The permit will contain a WET reopener provision.
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 by NetDMR, post-marked or entered into
NetDMR no later than the 28th day of the month following the completed reporting period. The first report is due on <<Month>> 28, 2024. 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

Pretreatment Monitoring and Reporting Requirements.The design capacity of the municipal wastewater treatment facility is less than 5 MGD; therefore the permittee will not be required
to develop an Approved POTWPretreatment Program. However, in order to determine if development of an Approved POTWPretreatment Program is warranted, the permittee shall conduct an industrial
waste survey, as described in Part II.C.1.Monitoring will not be required of the permittee for the pretreatment requirements at this time. If changes occur monitoring may be required
for parameters not currently listed in the permit or current monitoring requirements may be required to be increased to determine the impact of an Industrial User or to investigate sources
of pollutant loading. This could include but is not limited to sampling of the influent and effluent of the wastewater treatment plant and within the collection system.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 I., or a pollutant of concern listed in the Local Limit
development document or determined by the Director, the permittee must report this information to the Pretreatment Coordinator for the Division of Water Quality. If the loading exceeds
the allowable headworks load, increase sampling must occur based on the requirements given by the Pretreatment Coordinator for the Division of Water Quality. If needed sampling may need
to occur to find the source(s) of the increase. This may include sampling of the collection system. Notification regarding the exceedances of the allowable headworks loading can be provided
via email. Industrial Wastes.The "Industrial Waste Survey" or “IWS” as required by Part II.B.1. consists of; Identifying each Industrial User (IU) and determining if the IU is a SignificantIndustrial
User (SIU), Determination of the qualitative and quantitative characteristics of each discharge, and Appropriate production data. The IWS must be maintained and updated with IU information
as necessary, to ensure that all IUs are properly permitted or controlled at all times. Updates must be submitted to the Director sixty (60) days following a change to the IWS.Notify
all Significant Industrial Users of their obligation to comply with applicable requirements under Subtitles C and D of the Resource Conservation and Recovery Act (RCRA).The permittee
must notify the Director of any new introductions by new or existing SIUs or any substantial change in pollutants from any major industrial source. Such notice must contain the information
described in 1. above, and be forwarded no later than sixty (60) days following the introduction or change.
General and Specific Prohibitions. The permittee must ensure that no IU violates any of the general or specific standards. If an IU is found violating a general or specific standard
the permittee must notify the Director within 24 hours of the event. The general prohibitions and the specific prohibitions apply to each User introducing pollutants into a POTW whether
or not the User is subject to other Pretreatment Standards or any national, State or local Pretreatment Requirements.
General prohibition Standards. A User may not introduce into a POTW any pollutant(s) which cause Pass Through or Interference.
Specific Prohibited Standards. Developed pursuant to Section 307 of The Water Quality Act of 1987 require that under no circumstances shall the permittee allow introduction of the following
pollutants into the waste treatment system from any User (40 CFR 403.5):
Pollutants which create a fire or explosion hazard in the publicly owned treatment works (POTW), including, but not limited to, waste-streams 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

Any trucked or hauled pollutants, except at discharge points designated by the POTW.
Any pollutant that causes Pass Through or Interference at the POTW.
Any prohibited standard which the permittee has adopted in an ordinance or rule to control IU discharge to the POTW.
In addition to the general and specific limitations expressed above, more specific pretreatment limitations have been and will be promulgated for specific industrial categories under
Section 307 of the Water Quality Act of 1987 as amended (WQA). (See 40 CFR, Subchapter N, Parts 400 through 500, for specific information).
Significant Industrial Users Discharging to the POTW. The permittee shall provide adequate notice to the Director and the Division of Water Quality Pretreatment Coordinator of;
Any new introduction of pollutants into the treatment works from an indirect discharger (i.e., Industrial User) which would be subject to Sections 301 or 306 of the WQA if it were directly
discharging those pollutants;
Any substantial change in the volume or character of pollutants being introduced into the treatment works by a source introducing pollutants into the treatment works at the time of issuance
of the permit; and
For the purposes of this section, adequate notice shall include information on:
The quality and quantity of effluent to be introduced into such treatment works; and,
Any anticipated impact of the change on the quantity or quality of effluent to be discharged from such publicly owned treatment works.
Any IU that must comply with applicable requirements under Subtitles C and D of the Resource Conservation and Recovery Act (RCRA).
Change of Conditions.At such time as a specific pretreatment limitation becomes applicable to an Industrial User of the permittee, the Director may, as appropriate, do the following:
Amend the permittee's UPDES discharge permit to specify the additional pollutant(s) and corresponding effluent limitation(s) consistent with the applicable national pretreatment limitation;
Require the permittee to specify, by ordinance, contract, or other enforceable means, the type of pollutant(s) and the maximum amount which may be discharged to the permittee's facility
for treatment. Such requirement shall be imposed in a manner consistent with the POTW program development requirements of the General Pretreatment Regulations at 40 CFR 403;
Require the permittee to monitor its discharge for any pollutant, which may likely be discharged from the permittee's facility, should the Industrial User fail to properly pretreat its
waste; and/or
Require the permittee to develop an Approved POTW Pretreatment Program.
Legal Action. The Director retains, at all times, the right to take legal action against the Industrial User and/or the treatment works, in those cases where a permit violation has occurred
because of the failure of an Industrial User to discharge at an acceptable level. If the permittee has failed to properly delineate maximum acceptable industrial contributor levels,
the Director will look primarily to the permittee as the responsible party.
Local Limits.If Local Limits are developed per R317-8-8.5(4)(b) to protect the POTW from Pass Through or Interference, then the POTW must submit limits to DWQ for review and public notice,
as required by R317-8-8.5(4)(c). Local Limitsshould be developed in accordance with the latest revision of the EPA Local Limits Development Guidance and per R317-8-8.5. BOILERPLATE FOR
NON-PRETREATMENT MAJOR FACILITIESDefinitions. For this section the following definitions shall apply:Indirect Discharge means the introduction of pollutants into a publicly-owned treatment
works (POTW) from any non-domestic source regulated under section 307 (b), (c) or (d) of the CWA. Interference means a discharge which, alone or in conjunction with a discharge or discharges
from other sources, both:Inhibits or disrupts the POTW, its treatment processes or operations, or its sludge processes, use or disposal; andTherefore is a cause of a violation of any
requirement of the POTW's NPDES permit (including an increase in the magnitude or duration of a violation) or of the prevention of sewage sludge use or disposal in compliance with the
following statutory provisions and regulations or permits issued thereunder (or more stringent State or local regulations): Section 405 of the Clean Water Act, the Solid Waste Disposal
Act (SWDA) (including title II, more commonly referred to as the Resource Conservation and Recovery Act (RCRA), and including State regulations contained in any State sludge management
plan prepared pursuant to subtitle D of the SWDA), the Clean Air Act, the Toxic Substances Control Act, and the Marine Protection, Research and Sanctuaries Act.Local Limit is defined
as a limit designed to prevent Pass Through or Interference. And is developed in accordance with 40 CFR 403.5(c).Pass Through means a Discharge which exits the POTW into waters of the
United States in quantities or concentrations which, alone or in conjunction with a discharge or discharges from other sources, is a cause of a violation of any requirement of the POTW's
NPDES permit (including an increase in the magnitude or duration of a violation).Publicly Owned Treatment Works or POTW means a treatment works as defined by section 212 of the CWA,
which is owned by a State or municipality (as defined by section 502(4) of the CWA). This definition includes any devices and systems used in the storage, treatment, recycling and reclamation
of municipal sewage or industrial wastes of a liquid nature. It also includes sewers, pipes and other conveyances only if they convey wastewater to a POTW Treatment Plant. The term also
means the municipality as defined in section 502(4) of the CWA, which has jurisdiction over the Indirect Discharges to and the discharges from such a treatment works.Significant Industrial
User (SIU) is defined as an Industrial User discharging to a POTW that satisfies any of the following: Has a process wastewater flow of 25,000 gallons or more per average work day;Has
a flow greater than five percent of the flow carried by the municipal system receiving the waste; Is subject to Categorical Pretreatment Standards, or Has a reasonable potential for
adversely affecting the POTW's operation or for violating any pretreatment standard or requirement.User or Industrial User (IU) means a source of Indirect Discharge
Pretreatment Monitoring and Reporting Requirements.The design capacity of the municipal wastewater treatment facility is less than 5 MGD; therefore the permittee will not be required
to develop an Approved POTWPretreatment Program. However, in order to determine if development of an Approved POTWPretreatment Program is warranted, the permittee shall conduct an industrial
waste survey, as described in Part II.C.1.Monitoring will be required of the permittee for the pretreatment requirements at this time. If changes occur monitoring may be required for
parameters not currently listed in the permit or current monitoring requirements may be required to be increased to determine the impact of an Industrial User or to investigate sources
of pollutant loading. This could include but is not limited to sampling of the influent and effluent of the wastewater treatment plant and within the collection system.Influent and Effluent
Monitoring and Reporting Requirements. The permittee shall sample and analyze both the influent and effluent, for the parameters listed in the Pretreatment Monitoring Table.Pretreatment

of the test method used for analysis must be below this limit, if a test method is not available the permittee must submit documentation to the Director regarding the method that will
be usedIn addition, the permittee shall analyze the treatment facility influent and effluent for the presence of the toxic pollutants listed in 40 CFR 122 Appendix D Table II. If expected
to be present surfactants and 40 CFR 122 Appendix D Table V must be sampled yearly. 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 Organic Toxic Pollutants shall be submitted along with the Discharge Monitoring Report (DMR) at the end of the earliest possible
reporting period. Also, the permittee must submit a copy of the Organic Toxic Pollutants data to the Pretreatment Coordinator for the Division of Water Quality via email. 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.B.3. or Part I, or a pollutant of concern listed
in the Local Limit development document or determined by the Director, the permittee must report this information to the Pretreatment Coordinator for the Division of Water Quality. If
the loading exceeds the allowable headworks load, increase sampling must occur based on the requirements given by the Pretreatment Coordinator for the Division of Water Quality. If needed
sampling may need to occur to find the source(s) of the increase. This may include sampling of the collection system. Notification regarding the exceedances of the allowable headworks
loading can be provided via email. Industrial Wastes.The "Industrial Waste Survey" or “IWS” as required by Part II.B.1. consists of; Identifying each Industrial User (IU) and determining

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.
Additional Record Keeping Requirements Specific to Biosolids.
Unless otherwise required by the Director, the permittee is not required to keep records on compost products if the permittee prepared themfrom biosolids that meet the limits in Table
3 (Part III.B.1), the Class A pathogen requirements in Part III.B.2 and the vector attraction reduction requirements in Part III.B.3. The Director may notify the permittee that additional
record keeping is required if it is determined to be significant to protecting public health and the environment.
The permittee is required to keep the following information for at least 5 years:
Concentration of each heavy metal in Table 3 (Part III.B.1).
A description of how the pathogen reduction requirements in Part III.B.2 were met.
A description of how the vector attraction reduction requirements in Part III.B.3 were met.
A description of how the management practices in Part III.C were met (if necessary).
The following certification statement:"I certify under the penalty of law, that the heavy metals requirements in Part III.B.1, the pathogen requirements in Part III.B.2, the vector attraction
requirements in Part III.B.3, the management practices in Part III.C. This determination has been made under my direction and supervision in accordance with the system designed to assure
that qualified personnel properly gather and evaluate the information used to determine that the pathogen requirements, the vector attraction reduction requirements and the management
practices have been met. I am aware that there are significant penalties for false certification including the possibility of imprisonment."
The permittee shall retain records of all monitoring information, including all calibration and maintenance records and all original strip chart recordings for continuous monitoring
instrumentation, copies of all reports required by this permit and records of all data used to complete the application for this permit for the life of the permit. Data collected on
site, copies of Biosolids Report forms, and a copy of this UPDES biosolids-only permit must be maintained on site during the duration of activity at the permitted location.The State
of Utah has adopted the 40 CFR Part 503 federal regulations for the disposal of sewage sludge (biosolids) by reference. However, since this facility is a lagoon, there is not any regular
sludge production. Therefore 40 CFR Part 503 does not apply at this time. In the future, if the sludge needs to be removed from the lagoons and is disposed in some way, the Division
of Water Quality must be contacted prior to the removal of the sludge to ensure that all applicable state and federal regulations are met.
STORM WATER REQUIREMENTS.
Industrial Storm Water Permit. Based on the type of industrial activities occurring at the facility, the permittee is required to maintain separate coverage or an appropriate exclusion
under the Multi-Sector General Permit (MSGP) for Storm Water Discharges Associated with Industrial Activities (UTR000000). If the facility is not already covered, the permittee has 30
days from when this permit is issued to submit the appropriate Notice of Intent (NOI) for the MSGP or exclusion documentation.
Construction Storm Water Permit. Any construction at the facility that disturbs an acre or more of land, including less than an acre if it is part of a common plan of development or
sale, is required to obtain coverage under the UPDES Construction General Storm Water Permit (UTRC00000). Permit coverage must be obtained prior to land disturbance. If the site qualifies,
a Low Erosivity Waiver (LEW) Certification may be submitted instead of permit coverage.
MONITORING, RECORDING & GENERAL REPORTING REQUIREMENTS
Representative Sampling. Samples taken in compliance with the monitoring requirements established under Part I shall be collected from the effluent stream prior to discharge into the
receiving waters. Samples and measurements shall be representative of the volume and nature of the monitored discharge. Samples of biosolids shall be collected at a location representative
of the quality of biosolids immediately prior to the use-disposal practice.
Monitoring Procedures.Monitoring must be conducted according to test procedures approved under Utah Administrative Code ("UAC'') R317-2-10, UAC R317-8-4.1(10)(d), and/or 40 CFR 503 utilizing
sufficiently sensitive test methods unless other test procedures have been specified in this permit. Monitoring must be conducted according to the test procedures listed above unless
another method is required under 40 CFR subchapters N or O. Sufficiently sensitive test method means: (1) The method minimum level (ML) is at or below the level of the effluent limit
established in the permit for the measured pollutant or pollutant parameter; or(2) The method has the lowest ML of the analytical methods approved under 40 CFR part 136 or required under
40 CFR chapter I, subchapter N or O for the measured pollutant or pollutant parameter as per40 CFR 122.44(i)(1)(iv)(A).
Penalties for Tampering. The Act provides that any person who falsifies, tampers with, or knowingly renders inaccurate, any monitoring device or method required to be maintained under
this permit shall, upon conviction, be punished by a fine of not more than $10,000 per violation, or by imprisonment for not more than six months per violation, or by both.

of credentials and other documents as may be required by law, will be permitted to enter without delay for the purposes of performing their responsibilities.
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. Any person who willfully or negligently violates permit conditions or the Act is subject to a fine not exceeding $25,000 per day of violation.
Any person convicted under The Act Section 19-5-115(2) a second time shall be punished by a fine not exceeding $50,000 per day. 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 PartVI.G.2 and 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 PartVI.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.
Toxic Pollutants. The permittee shall comply with effluent standards or prohibitions established under Section 307(a) of The Water Quality Act of 1987 for toxic pollutants within the
time provided in the regulations that establish those standards or prohibitions, even if the permit has not yet been modified to incorporate the requirement.
Changes in Discharge of Toxic Substances. Notification shall be provided to the Executive Secretary as soon as the permittee knows of, or has reason to believe:That any activity has
occurred or will occur which would result in the discharge, on a routine or frequent basis, of any toxic pollutant which is not limited in the permit, if that discharge will exceed the
highest of the following "notification levels":
One hundred micrograms per liter (100 ug/L);
Two hundred micrograms per liter (200 ug/L) for acrolein and acrylonitrile; five hundred micrograms per liter (500 ug/L) for 2,4-dinitrophenol and for 2-methyl-4, 6-dinitrophenol; and
one milligram per liter (1 mg/L) for antimony;
Five (5) times the maximum concentration value reported for that pollutant in the permit application in accordance with UAC R317-8-3.4(7) or (10); or,
The level established by the Executive Secretary in accordance with UAC R317-8-4.2(6).
That any activity has occurred or will occur which would result in any discharge, on a non-routine or infrequent basis, of a toxic pollutant which is not limited in the permit, if that
discharge will exceed the highest of the following "notification levels":\
Five hundred micrograms per liter (500 ug/L);
One milligram per liter (1 mg/L) for antimony:
Ten (10) times the maximum concentration value reported for that pollutant in the permit application in accordance with UACR317-8-3.4(9); or,
The level established by the Executive Secretary in accordance with UACR317-8-4.2(6).
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.

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.4.a and/or b (depending on whether or not the permit requires both acute and chronic WET testing) of 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.Use the following paragraph if there is no WET testing is required at the facility:This permit may be reopened and modified (following proper administrative procedures) to include
WET testing, a WET limitation, a compliance schedule, a compliance date, additional or modified numerical limitations, or any other conditions related to the control of toxicants if
toxicity is detected during the life of this 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.

year divided by the number of monthly discharges measured during that year.
“Bypass,” means the diversion of waste streams from any portion of a treatment facility.
“Chronic toxicity” occurs when the IC25< XX% effluent. The XX% effluent is the concentration of the effluent in the receiving water, at the end of the mixing zone expressed as per cent
effluent.
"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.

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.
