Narrative Standard. It shall be unlawful, and a violation of this permit, for the permittee to discharge or place any waste or other substance in such a way as will be or may become offensive such as unnatural deposits, floating debris, oil, scum, or other nuisances such as color, odor or taste, or cause conditions which produce undesirable aquatic life or which produce objectionable tastes in edible aquatic organisms; or result in concentrations or combinations of substances which produce undesirable physiological responses in desirable resident fish, or other desirable aquatic life, or undesirable human health effects, as determined by a bioassay or other tests performed in accordance with standard procedures. Specific Limitations and Self-Monitoring Requirements. Effective immediately and lasting the duration of this permit, there shall be no acute or chronic toxicity fromthedischarging Outfalls, as defined in Part VIIandas determined by test procedures described in Part I.C. of this permit. Effective immediately and lasting the duration of this permit, the permittee is authorized to discharge from all Outfalls listed in this permit. Such discharges shall be limited and monitored by the permittee as specified below: Parameter Effluent Limitations *a Maximum Monthly Avg Maximum Weekly Avg Daily Minimum Daily Maximum Total Flow *b 3.0 -- -- -- TSS, mg/L -- -- -- 70 Sulfate, mg/L -- -- -- 3,209 TDS, mg/L *g -- -- -- 4,766 Oil & Grease, mg/L*c -- -- -- 10.0 pH, Standard Units -- -- 6.5 9.0 Total Iron, mg/L -- -- -- 1.4 WET Chronic Biomonitoring *d -- -- -- IC25> 57.6% effluent Sanitary Waste *c -- -- -- None Turbidity *e -- -- -- Report Self-Monitoring and Reporting Requirements *a Parameter Frequency Sample Type Units Total Flow *b Twice Monthly Recorded MGD TSS Twice Monthly Grab mg/L Total Iron Twice Monthly Grab mg/L pH Twice Monthly Grab SU Oil & Grease *c Twice Monthly Visual Yes/No Oil & Grease *c When Sheen Observed Grab mg/L TDS, mg/L *g Twice Monthly Composite mg/L Sulfate, mg/L Twice Monthly Composite mg/L Sanitary Waste *c Twice Monthly Visual Yes/No Turbidity *e Twice Monthly Grab NTU WET – Biomonitoring *d Ceriodaphnia dubia - Chronic Fathead Minnows - Chronic Quarterly, Alternating Species each quarter when mine is discharging.

Effluent limits apply to all outfalls unless otherwise stated. *bTotal EffluentFlow is limited to 3.0 MGD as a thirty-day average from all discharging outfalls combined. Flow measurements of effluent volume shall be made in such a manner that the permittee can affirmatively demonstrate that representative values are being obtained. *cA visual inspection for any oil and grease sheen, sanitary wastes, floating solids, and visible foam shall be performed at leasttwice per month at all Outfalls. There shall be no visible sheen, floating solids, or visible foam in other than trace amounts upon any discharges and there shall be no discharge of any sanitary wastes at any time. If a sheen is observeddischarging from any Outfall, then a sample of the effluent shall be collected immediately thereafter and the oil and grease shall not exceed 10 mg/L in concentration. *dChronic WET monitoring is required for mine water discharges from Outfalls 001, 003, 004and 005 only. The chronic WET testing shall alternate the test species as detailed in the permit. *eTurbidity monitoring shall be conducted twice monthly from all discharging Outfalls and from the receiving water whenever possible. *fStarting on the effective date of this permit, the following total and dissolved metals shall be monitored quarterly for at least two years and until at least 10 sampling events are competed from all discharging outfalls; Arsenic, Cadmium, Chromium, Copper, Lead, Mercury, Nickel, Selenium, Silver and Zinc. The permittee is required to utilize the lowest detection limit possible using sufficiently sensitive standard test methods and certified laboratories. Once at least 10 sampling events have been completed, the permittee may request a permit modification based upon a subsequent reasonable potential analysis for a reduction in testing frequency and/or removal of any applicable metals parameters as appropriate. The permit issuing authority may approve or deny the request based on the results and other available information. *gWithin two years from the effective date of this permit, the permittee shall complete and submit to the Director, a TDS loading evaluation and exemption demonstration report in accordance with the Colorado River Basin Salinity Control Forum NPDES Policies entitled, “2020 Review, Water Quality Standards for Salinity, Colorado River System, Appendix B.” Samples collected in compliance with the monitoring requirements specified above shall be collected at all Outfalls prior to mixing with any receiving water. Should any discharge or increase in the volume of a discharge caused by precipitation within any 24-hour period that is less than or equal to the 10-year, 24-hour precipitation event (or snowmelt of equivalent volume), may at Outfalls 002, 006, 007, 008 and 009 only, substitute the following Settleable Solids limitation for the TSS limitation contained inPartI.C.2.All other limitationsnot included below remain unchanged. Parameter, Units Alternative Effluent Limitations Daily Minimum Daily Maximum Settleable Solids (SS), milliliter/liter -- 0.5 Total Suspended Solids (TSS), mg/L -- ReportIn order to substitute the above limitations, the sample collected during the storm event must be analyzed for all permitted parameters specified under Part I.C.2. Such analyses shall be conducted on either grab or composite samples. Should any discharge or increase in the volume of a discharge caused by precipitation within any 24-hour period that is greater than the 10-year, 24-hour precipitation event (or snowmelt of equivalent volume), may at Outfalls 002, 006, 007, 008 and 009 only, comply with the following effluent limitationsonly instead of the limitations contained in PartI.C.2: Parameter, UnitsEffluent LimitationsDaily MinimumDaily MaximumpH, SU6.59.0In order to substitute the above limitation, the sample collected during the storm event must be analyzed and reported for all permitted parameters specified under Part I.C.2. Such analyses shall be conducted on either grab or composite samples. The operator shall have the burden of proof that the increase in discharge was caused by the applicable precipitation event described in Part I.C.4 and I.C.5. The alternate limitations in Part I.C.4and I.C.5 shall not apply to the mine water discharges (i.e. Outfalls 001, 003, 004 & 005). The alternate limitations shall apply to Outfalls 002, 006, 007, 008 and 009 only. For rainfall, to waive TSS or anyother applicable limitations, the permittee must prove that the discharge occurred during the precipitation event, or within 48 hours after measurable precipitation has stopped. In addition, to waive settleable solids limitations, the permittee must prove that the discharge occurred during the precipitation event, or within 48 hours after precipitation greater than the 10-year, 24-hour event has stopped. For snowmelt, to waive TSS or any other applicable any limitations, the permittee must prove that the discharge occurred during pond inflow from the snow melt event, or within 48 hours after pond inflow has stopped. In addition, to waive settleable solids limitations, the permittee must prove that the discharge occurred during pond inflow from the snow melt event, or within 48 hours after pond inflow volume greater than the 10-year, 24-hour event has stopped. The permittee must submit documentation that the treatment facilities were properly operated and maintained prior to and during the storm event with any request for relief from primary limitations. The division shall determine the adequacy of proof. As part of this determination, the division shall evaluate whether the permittee could have controlled the discharge in such a manner that primary limitations could have been met, whether proper sediment storage levels were maintained and the ponds had sufficient water and sediment capacity for the storm event, plus other relevant factors. Any manual pond dewatering that is not part of a storm event discharge must meet all limitations of Part I.C.2. All data and documentation required by the permittee which cannot be reported on applicable discharge monitoring report forms (DMRs) through NetDMR, shall be submittedseparately to the Director. Submittal of documentation of containment, maintenance and precipitation records above does not exempt the permittee from the notification requirements of this permit. Whole Effluent Testing - Chronic Toxicity.Starting on the effective date of this permit, the permittee shall quarterly conduct chronic short-term toxicity tests on a composite sample of the final effluent. The sample shall be collected atdischarging Outfalls001, 003, 004 & 005before mixing with the receiving water.Three samples are required and samples shall be collected on Monday, Wednesday and Friday of each sampling period or collected on a two-day progression for each sampling period. This may be changed with Director approval. The chronic toxicity tests shall be conducted in general accordance with the procedures set out in the latest revision of Short-Term Methods for Estimating the Chronic Toxicity of Effluents and Receiving Water to Freshwater Organisms, Fourth Edition, October 2002, EPA—821-R-02-013as per 40 CFR 136.3(a) TABLE IA-LIST OF APPROVED BIOLOGICAL METHODS.Alternating test species shall consist of Ceriodaphnia dubia and Pimephales promelas (fathead minnow). A multi dilution test consisting of at least five concentrations and a control is required at two dilutions below and two above the RWC, if possible. If test acceptability criteria are not met for control survival, growth, or reproduction, the test shall be considered invalid. A valid replacement test is required within the specified sampling period to remain in compliance with this permit. Chronic toxicity occurs when, during a chronic toxicity test, the 25% inhibition concentration (IC25) calculated on the basis of test organism survival and growth or survival and reproduction is less than or equal to 57.6% effluent concentration. If a sample is found to be chronically toxic during a routine test, the monitoring frequency shall become biweekly (see Accelerated Testing below). A CO2 atmosphere may be used (in conjunction with an unmodified test) in order to account for pH drift. If possible, dilution water should be obtained from the receiving stream.Quarterly test results shall be reported along with the Discharge Monitoring Report (DMR) submitted for the end of the required reporting period (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, Utah Division of Water Quality, February, 2018. If the results for ten consecutive tests indicate no chronic toxicity, the permittee may submit a request to the Director to allow a reduction in chronic toxicity testing by alternating species, frequency, using only the most sensitive species, or potentially changing from chronic to acute testing. The permit issuing authority may approve or deny the request based on the results and other available information and without further public notice. If the request is approved, the test procedures are to be the same as specified above for the test species. 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 belowPattern 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) 2 consecutive 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 belowToxicity Reduction Evaluation.If 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 CharacterizationPhase II – Toxicity Identification ProceduresPhase III – Toxicity Control ProceduresAny 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 Wastewater Monitoring Results. Monitoring results obtained during the previous month shall be summarized for each month and reported by NetDMR, or on a Discharge Monitoring Report Form (EPA No. 3320-1)* post-marked or entered into NetDMR no later than the 28th day of the month following the completed reporting period. If no discharge occurs during the reporting period, “no discharge” shall be reported. Legible copies of these, and all other reports including whole effluent toxicity (WET) test reports required herein, shall be signed and certified in accordance with the requirements of Signatory Requirements (see Part VI.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 84114-4870_________________________* Starting January 1, 2017 monitoring results must be submitted using NetDMR unless the permittee has successfully petitioned for an exception.

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 UCA 19-5-115(2) a second time shall be punished by a fine not exceeding $50,000 per day. Except as provided at Part IV.G, Bypass of Treatment Facilities and Part IV.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 V.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 Part V.G.2.a (1), (2) and (3). Notice. Anticipated bypass. Except as provided above in Part V.G.2 and below in Part V.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 V.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 V.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 could significantly change the nature or increase the quantity of parameters discharged or pollutant sold or given away. This notification applies to pollutants, which are not subject to effluent limitations in the permit. In addition, if there are any planned substantial changes to the permittee's existing sludge facilities or their manner of operation or to current sludge management practices of storage and disposal, 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.

DEFINITIONSWastewater. “7-day and weekly average” is the arithmetic average of all samples collected during a consecutive 7-day period or calendar week whichever is applicable. 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, beginning on Sunday and ending 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 the Saturday. “10-year, 24-hour precipitation event” means the maximum 24-hour precipitation event with a probable recurrence interval of once in 10 years. This information is available in Weather Bureau Technical Paper No. 40, May 1961 and National Oceanographic and Atmospheric Administration Atlas 2, 1973 for the 11 Western States, and may be obtained from the National Climatic Center of the Environmental Data Service, National Oceanic and Atmospheric Administration, U.S. Department of Commerce. “30-day and monthly average” is the arithmetic average of all samples collected during a consecutive 30-day period or calendar month, whichever is applicable. The calendar month shall be used for purposes of reporting self-monitoring data on discharge monitoring report forms. “Act,” means the Utah Water Quality Act. “Bypass,” means the diversion of waste streams from any portion of a treatment facility. “Chronic toxicity” occurs when the survival, growth, or reproduction for either test species exposed to a specific percent effluent dilution is significantly less (at the 95 percent confidence level) than the survival, growth, or reproduction of the control specimens. A five-dilution test will be used. “Coal pile runoff” means the rainfall runoff from or through any coal storage pile. “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 the Utah 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. “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. “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. “Storm water” means storm water runoff, snowmelt runoff, and surface runoff and drainage. “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. Industrial Pretreatment Definitions. The following definitions shall apply only if the permittee discharges wastewater to a POTW:Indirect Discharge means the introduction of pollutants into a 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 UPDES 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 SWDA, the Clean Air Act, the Toxic Substances Control Act, and the Marine Protection Act.Pass Through means a Discharge which exits the POTW into waters of the U.S. in quantities or concentrations which, alone or in conjunction with 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.
