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 byNetDMR, 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,
20--. 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 REQUIREMENTSDefinitions. 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.Pass Through means a Discharge which exits the POTW into waters of
the State or 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)means:Except as provided in paragraphs (5)(b) and (5)(c) of this definition, the term Significant Industrial User means: All Industrial
Users subject to Categorical Pretreatment Standards under 40 CFR 403.6 and 40 CFR chapter I, subchapter N; and Any other Industrial User that: discharges an average of 25,000 gallons
per day or more of process wastewater to the POTW (excluding sanitary, noncontact cooling and boiler blowdown wastewater); contributes a process wastestream which makes up 5 percent
or more of the average dry weather hydraulic or organic capacity of the POTW Treatment plant; or is designated as such by the Control Authority on the basis that the Industrial User
has a reasonable potential for adversely affecting the POTW's operation or for violating any Pretreatment Standard or requirement (in accordance with 40 CFR 403.8(f)(6)). The Control
Authority may determine that an Industrial User subject to categorical Pretreatment Standards under § 403.6 and 40 CFR chapter I, subchapter N is a Non-Significant Categorical Industrial
User rather than a Significant Industrial User on a finding that the Industrial User never discharges more than 100 gallons per day (gpd) of total categorical wastewater (excluding sanitary,
non-contact cooling and boiler blowdown wastewater, unless specifically included in the Pretreatment Standard) and the following conditions are met: The Industrial User, prior to the
Control Authority's finding, has consistently complied with all applicable categorical Pretreatment Standards and Requirements; The Industrial User annually submits the certification
statement required in § 403.12(q) together with any additional information necessary to support the certification statement; and The Industrial User never discharges any untreated concentrated
wastewater. Upon a finding that an Industrial User meeting the criteria in paragraph (5)(a)(2) of this definition has no reasonable potential for adversely affecting the POTW's operation
or for violating any Pretreatment Standards or requirement, the Control Authority may at any time, on its own initiative or in response to a petition received from an Industrial User
or POTW, and in accordance with 40 CFR 403.8(f)(6), determine that such Industrial User is not a Significant Industrial User.User or Industrial User (IU) means a source of Indirect Discharge.Discharge

to POTW. Any wastewaters discharged to the sanitary sewer, either as a direct discharge or as a hauled waste, are subject to Federal, State and local pretreatment regulations. Pursuant
to Section 307 of The Water Quality Act of 1987, the Permittee shall comply with all applicable federal General Pretreatment Regulations promulgated at 40 CFR 403, the State Pretreatment
Requirements at UAC R317-8-8, and any specific local discharge limitations developed by the Publicly Owned Treatment Works (POTW) accepting the wastewaters. At a minimum, the discharge
into a POTW must meet the requirements of Part II. D. and E. of the permit.Hazardous Waste Notification. The Permittee must notify the POTW, the EPA Regional Waste Management Director,
the Director and the State hazardous waste authorities in writing if they discharge any substance into a POTW that, if otherwise disposed of, would be considered a hazardous waste under
40 CFR 261. This notification must include the name of the hazardous waste, the EPA hazardous waste number, and the type of discharge (continuous or batch).General and Specific Prohibitions.
General Prohibitions. The Permittee may not introduce into a POTW any pollutant(s) which cause Pass Through or Interference. These general prohibitions and the specific prohibitions
in paragraph 2. of this section apply to the introducing pollutants into a POTW whether or not the Permittee is subject to other National Pretreatment Standards or any national, State,
or local Pretreatment Requirements.Specific Prohibitions. The following pollutants shall not be introduced into a POTW: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 Limitation established by the POTW.Categorical Standards. In addition to the general
and specific limitations expressed in Part II. D.of this section, applicable National Categorical Pretreatment Standards must be met by all Industrial Users discharging into a POTW.
These standards are published in the federal regulations at 40 CFR 405 through 471.
BIOSOLIDS REQUIREMENTSThe 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 an industrial facility that does not dispose of sanitary waste, 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 that will occur at the facility, the permittee will not be 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).
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. 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 Part VI.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.2 and below in Part VI.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.
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.
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. A duly authorized representative may thus be either a named
individual or any individual occupying a named position.
For a corporation. By a responsible corporate officer. For the purpose of this section, a responsible corporate officer means:
A president, secretary, treasurer, or vice-president of the corporation in charge of a principal business function, or any other person who perfoms similar policy- or decision-making
functions for the corporation, or
the manager of one or more manufacturing, production, or operating facilities, provided, the manager is authorized to make management decisions which govern the operation of the regulated
facility including having the explicit or implicit duty of making major capital investment recommendations, and initiating and directing other comprehensive measures to assure long term
environmental compliance with environmental laws and regulations; the manager can ensure that the necessary systems are established or actions taken to gather complete and accurate information
for permit application requirements; and where authority to sign documents has been assigned or delegated to the manager in accordance with corporate procedures.
For a partnership or sole proprietorship. By a general partner or the proprietor, respectively; or
For a municipality, State, Federal, or other public agency. By either a principal executive officer or ranking elected official. For purposes of this section, a principal executive
officer of a Federal agency includes:
The chief executive officer of the agency, or
a senior executive officer having responsibility for the overall operations of a principal geographic unit of the agency (e.g., Regional Administrators of EPA).
All reports required by the permit and other information requested by the Director shall be signed by a person described above or by a duly authorized representative of that person.

Changes to authorization. If an authorization under paragraph VII.G.2 is no longer accurate because a different individual or position has responsibility for the overall operation of
the facility, a new authorization satisfying the requirements of paragraph VII.G.2. must be submitted to the Director prior to or together with any reports, information, or applications
to be signed by an authorized representative.
Certification. Any person signing a document under this section shall make the following certification:

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.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.
"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 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.
“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.

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 byNetDMR, 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,
20--. 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 REQUIREMENTSDefinitions. 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.Pass Through means a Discharge which exits the POTW into waters of
the State or 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)means:Except as provided in paragraphs (5)(b) and (5)(c) of this definition, the term Significant Industrial User means: All Industrial
Users subject to Categorical Pretreatment Standards under 40 CFR 403.6 and 40 CFR chapter I, subchapter N; and Any other Industrial User that: discharges an average of 25,000 gallons
per day or more of process wastewater to the POTW (excluding sanitary, noncontact cooling and boiler blowdown wastewater); contributes a process wastestream which makes up 5 percent
or more of the average dry weather hydraulic or organic capacity of the POTW Treatment plant; or is designated as such by the Control Authority on the basis that the Industrial User
has a reasonable potential for adversely affecting the POTW's operation or for violating any Pretreatment Standard or requirement (in accordance with 40 CFR 403.8(f)(6)). The Control
Authority may determine that an Industrial User subject to categorical Pretreatment Standards under § 403.6 and 40 CFR chapter I, subchapter N is a Non-Significant Categorical Industrial
User rather than a Significant Industrial User on a finding that the Industrial User never discharges more than 100 gallons per day (gpd) of total categorical wastewater (excluding sanitary,
non-contact cooling and boiler blowdown wastewater, unless specifically included in the Pretreatment Standard) and the following conditions are met: The Industrial User, prior to the
Control Authority's finding, has consistently complied with all applicable categorical Pretreatment Standards and Requirements; The Industrial User annually submits the certification
statement required in § 403.12(q) together with any additional information necessary to support the certification statement; and The Industrial User never discharges any untreated concentrated
wastewater. Upon a finding that an Industrial User meeting the criteria in paragraph (5)(a)(2) of this definition has no reasonable potential for adversely affecting the POTW's operation
or for violating any Pretreatment Standards or requirement, the Control Authority may at any time, on its own initiative or in response to a petition received from an Industrial User
or POTW, and in accordance with 40 CFR 403.8(f)(6), determine that such Industrial User is not a Significant Industrial User.User or Industrial User (IU) means a source of Indirect Discharge.Discharge

to POTW. Any wastewaters discharged to the sanitary sewer, either as a direct discharge or as a hauled waste, are subject to Federal, State and local pretreatment regulations. Pursuant
to Section 307 of The Water Quality Act of 1987, the Permittee shall comply with all applicable federal General Pretreatment Regulations promulgated at 40 CFR 403, the State Pretreatment
Requirements at UAC R317-8-8, and any specific local discharge limitations developed by the Publicly Owned Treatment Works (POTW) accepting the wastewaters. At a minimum, the discharge
into a POTW must meet the requirements of Part II. D. and E. of the permit.Hazardous Waste Notification. The Permittee must notify the POTW, the EPA Regional Waste Management Director,
the Director and the State hazardous waste authorities in writing if they discharge any substance into a POTW that, if otherwise disposed of, would be considered a hazardous waste under
40 CFR 261. This notification must include the name of the hazardous waste, the EPA hazardous waste number, and the type of discharge (continuous or batch).General and Specific Prohibitions.
General Prohibitions. The Permittee may not introduce into a POTW any pollutant(s) which cause Pass Through or Interference. These general prohibitions and the specific prohibitions
in paragraph 2. of this section apply to the introducing pollutants into a POTW whether or not the Permittee is subject to other National Pretreatment Standards or any national, State,
or local Pretreatment Requirements.Specific Prohibitions. The following pollutants shall not be introduced into a POTW: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 Limitation established by the POTW.Categorical Standards. In addition to the general
and specific limitations expressed in Part II. D.of this section, applicable National Categorical Pretreatment Standards must be met by all Industrial Users discharging into a POTW.
These standards are published in the federal regulations at 40 CFR 405 through 471.
BIOSOLIDS REQUIREMENTSThe 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 an industrial facility that does not dispose of sanitary waste, 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 that will occur at the facility, the permittee will be 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.

The permittee shall make the necessary arrangements with the landowner or leaseholder to obtain permission or clearance, the Director, or authorized representative, upon the presentation
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. 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 Part VI.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.2 and below in Part VI.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.
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.
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:

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.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.
"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 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.
“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.
