3.1 Maintenance of Water Quality Waters whose existing quality is better than the established standards for the designated uses will be maintained at high quality unless it is determined by the Director, after appropriate intergovernmental coordination and public participation in concert with the Utah continuing planning process, allowing lower water quality is necessary to accommodate important economic or social development in the area in which the waters are located. However, existing instream water uses shall be maintained and protected. No water quality degradation is allowable which would interfere with or become injurious to existing instream water uses. In those cases where potential water quality impairment associated with a thermal discharge is involved, the antidegradation policy and implementing method shall be consistent with Section 316 of the Federal Clean Water Act. 3.2 Category 1 Waters Waters which have been determined by the Board to be of exceptional recreational or ecological significance or have been determined to be a State or National resource requiring protection, shall be maintained at existing high quality through designation, by the Board after public hearing, as Category 1 Waters. New point source discharges of wastewater, treated or otherwise, are prohibited in such segments after the effective date of designation. Protection of such segments from pathogens in diffuse, underground sources is covered in R317-5 and R317-7 and the rules for Individual Wastewater Disposal Systems (R317-501 through R317-515). Other diffuse sources (nonpoint sources) of wastes shall be controlled to the extent feasible through implementation of best management practices or regulatory programs. Discharges may be allowed where pollution will be temporary and limited after consideration of the factors in R317-2-3.5.b.4., and where best management practices will be employed to minimize pollution effects. Waters of the state designated as Category 1 Waters are listed in R317-2-12.1. 3.3 Category 2 Waters Category 2 Waters are designated surface water segments which are treated as Category 1 Waters except that a point source discharge may be permitted provided that the discharge does not degrade existing water quality. Discharges may be allowed where pollution will be temporary and limited after consideration of the factors in R317-2-.3.5.b.4., and where best management practices will be employed to minimize pollution effects. Waters of the state designated as Category 2 Waters are listed in R317-2-12.2. 3.4 Category 3 Waters For all other waters of the state, point source discharges are allowed and degradation may occur, pursuant to the conditions and review procedures outlined in Section 3.5. 3.5 Antidegradation Review (ADR) An antidegradation review will determine whether the proposed activity complies with the applicable antidegradation requirements for receiving waters that may be affected. An antidegradation review (ADR) may consist of two parts or levels. A Level I review is conducted to insure that existing uses will be maintained and protected. Both Level I and Level II reviews will be conducted on a parameter-by-parameter basis. A decision to move to a Level II review for one parameter does not require a Level II review for other parameters. Discussion of parameters of concern is those expected to be affected by the proposed activity. Antidegradation reviews shall include opportunities for public participation, as described in Section 3.5e. a. Activities Subject to Antidegradation Review (ADR) 1. For all State waters, antidegradation reviews will be conducted for proposed federally regulated activities, such as those under Clean Water Act Sections 401 (FERC and other Federal actions), 402 (UPDES permits), and 404 (Army Corps of Engineers permits). The Director may conduct an ADR on any projects with the potential for major impact on the quality of waters of the state. The review will determine whether the proposed activity complies with the applicable antidegradation requirements for the particular receiving waters that may be affected. 2. For Category 1 Waters and Category 2 Waters, reviews shall be consistent with the requirement established in Sections 3.2 and 3.3, respectively. 3. For Category 3 Waters, reviews shall be consistent with the requirements established in this section b. An Anti-degradation Level II review is not required where any of the following conditions apply: 1. Water quality will not be lowered by the proposed activity or for existing permitted facilities, water quality will not be further lowered by the proposed activity, examples include situations where: (a) the proposed concentration-based effluent limit is less than or equal to the ambient concentration in the receiving water during critical conditions; or (b) a UPDES permit is being renewed and the proposed effluent concentration and loading limits are equal to or less than the concentration and loading limits in the previous permit; or (c) a UPDES permit is being renewed and new effluent limits are to be added to the permit, but the new effluent limits are based on maintaining or improving upon effluent concentrations and loads that have been observed, including variability; or 2. Assimilative capacity (based upon concentration) is not available or has previously been allocated, as indicated by water quality monitoring or modeling information. This includes situations where: (a) the water body is included on the current 303(d) list for the parameter of concern; or (b) existing water quality for the parameter of concern does not satisfy applicable numeric or narrative water quality criteria; or (c) discharge limits are established in an approved TMDL that is consistent with the current water quality standards for the receiving water (i.e., where TMDLs are established, and changes in effluent limits that are consistent with the existing load allocation would not trigger an antidegradation review). Under conditions (a) or (b) the effluent limit in an UPDES permit may be equal to the water quality numeric criterion for the parameter of concern. 3. Water quality impacts will be temporary and related only to sediment or turbidity and fish spawning will not be impaired, 4. The water quality effects of the proposed activity are expected to be temporary and limited. As general guidance, CWA Section 402 general discharge permits, CWA Section 404 general permits, or activities of short duration, will be deemed to have a temporary and limited effect on water quality where there is a reasonable factual basis to support such a conclusion. Factors to be considered in determining whether water quality effects will be temporary and limited may include the following: (a) Length of time during which water quality will be lowered. (b) Percent change in ambient concentrations of pollutants of concern (c) Pollutants affected (d) Likelihood for long-term water quality benefits to the segment (e.g., dredging of contaminated sediments) (e) Potential for any residual long-term influences on existing uses. (f) Impairment of the fish spawning, survival and development of aquatic fauna excluding fish removal efforts. c. Anti-degradation Review Process For all activities requiring a Level II review, the Division will notify affected agencies and the public with regards to the requested proposed activity and discussions with stakeholders may be held. In the case of Section 402 discharge permits, if it is determined that a discharge will be allowed, the Director will develop any needed UPDES permits for public notice following the normal permit issuance process. The ADR will cover the following requirements or determinations: 1. Will all Statutory and regulatory requirements be met? The Director will review to determine that there will be achieved all statutory and regulatory requirements for all new and existing point sources and all required cost-effective and reasonable best management practices for nonpoint source control in the area of the discharge. If point sources exist in the area that have not achieved all statutory and regulatory requirements, the Director will consider whether schedules of compliance or other plans have been established when evaluating whether compliance has been assured. Generally, the "area of the discharge" will be determined based on the parameters of concern associated with the proposed activity and the portion of the receiving water that would be affected. 2. Are there any reasonable less-degrading alternatives? There will be an evaluation of whether there are any reasonable non-degrading or less degrading alternatives for the proposed activity. This question will be addressed by the Division based on information provided by the project proponent. Control alternatives for a proposed activity will be evaluated in an effort to avoid or minimize degradation of the receiving water. Alternatives to be considered, evaluated, and implemented to the extent feasible, could include pollutant trading, water conservation, water recycling and reuse, land application, total containment, etc. For proposed UPDES permitted discharges, the following list of alternatives should be considered, evaluated and implemented to the extent feasible: (a) innovative or alternative treatment options (b) more effective treatment options or higher treatment levels (c) connection to other wastewater treatment facilities (d) process changes or product or raw material substitution (e) seasonal or controlled discharge options to minimize discharging during critical water quality periods (f) pollutant trading (g) water conservation (h) water recycle and reuse (i) alternative discharge locations or alternative receiving waters (j) land application (k) total containment (l) improved operation and maintenance of existing treatment systems (m) other appropriate alternatives An option more costly than the cheapest alternative may have to be implemented if a substantial benefit to the stream can be realized. Alternatives would generally be considered feasible where costs are no more than 20% higher than the cost of the discharging alternative, and (for POTWs) where the projected per connection service fees are not greater than 1.4% of MAGHI (median adjusted gross household income), the current affordability criterion now being used by the Water Quality Board in the wastewater revolving loan program. Alternatives within these cost ranges should be carefully considered by the discharger. Where State financing is appropriate, a financial assistance package may be influenced by this evaluation, i.e., a less polluting alternative may receive a more favorable funding arrangement in order to make it a more financially attractive alternative. It must also be recognized in relationship to evaluating options that would avoid or reduce discharges to the stream, that in some situations it may be more beneficial to leave the water in the stream for instream flow purposes than to remove the discharge to the stream. 3. Does the proposed activity have economic and social importance? Although it is recognized that any activity resulting in a discharge to surface waters will have positive and negative aspects, information must be submitted by the applicant that any discharge or increased discharge will be of economic or social importance in the area. The factors addressed in such a demonstration may include, but are not limited to, the following: (a) employment (i.e., increasing, maintaining, or avoiding a reduction in employment); (b) increased production; (c) improved community tax base; (d) housing; (e) correction of an environmental or public health problem; and (f) other information that may be necessary to determine the social and economic importance of the proposed surface water discharge. 4. The applicant may submit a proposal to mitigate any adverse environmental effects of the proposed activity (e.g., instream habitat improvement, bank stabilization). Such mitigation plans should describe the proposed mitigation measures and the costs of such mitigation. Mitigation plans will not have any effect on effluent limits or conditions included in a permit (except possibly where a previously completed mitigation project has resulted in an improvement in background water quality that affects a water quality-based limit). Such mitigation plans will be developed and implemented by the applicant as a means to further minimize the environmental effects of the proposed activity and to increase its socio-economic importance. An effective mitigation plan may, in some cases, allow the Director to authorize proposed activities that would otherwise not be authorized. 5. Will water quality standards be violated by the discharge? Proposed activities that will affect the quality of waters of the state will be allowed only where the proposed activity will not violate water quality standards. 6. Will existing uses be maintained and protected? Proposed activities can only be allowed if "existing uses" will be maintained and protected. No UPDES permit will be allowed which will permit numeric water quality standards to be exceeded in a receiving water outside the mixing zone. In the case of nonpoint pollution sources, the non-regulatory Section 319 program now in place will address these sources through application of best management practices to ensure that numeric water quality standards are not exceeded. 7. If a situation is found where there is an existing use which is a higher use (i.e., more stringent protection requirements) than that current designated use, the Director will apply the water quality standards and anti-degradation policy to protect the existing use. Narrative criteria may be used as a basis to protect existing uses for parameters where numeric criteria have not been adopted. Procedures to change the stream use designation to recognize the existing use as the designated use would be initiated. d. Special Procedures for Drinking Water Sources Depending upon the locations of the discharge and its proximity to downstream drinking water diversions, additional treatment or more stringent effluent limits or additional monitoring, beyond that which may otherwise be required to meet minimum technology standards or in stream water quality standards, may be required by the Director in order to adequately protect public health and the environment. Such additional treatment may include additional disinfection, suspended solids removal to make the disinfection process more effective, removal of any specific contaminants for which drinking water maximum contaminant levels (MCLs) exists, and/or nutrient removal to reduce the organic content of raw water used as a source for domestic water systems. Additional monitoring may include analyses for viruses, Giardia, Cryptosporidium, other pathogenic organisms, and/or any contaminant for which drinking water MCLs exist. Depending on the results of such monitoring, more stringent treatment may then be required. The additional treatment/effluent limits/monitoring which may be required will be determined by the Director after consultation with the Division of Drinking Water and the downstream drinking water users. e. Public Notice The public will be provided notice and an opportunity to comment on the conclusions of all completed antidegradation reviews. When possible, public notice on the antidegradation review conclusions will be combined with the public notice on the proposed permitting or certifying action. In the case of UPDES permits, public notice will be provided through the normal permitting process, as all draft permits are public noticed for 30 days, and public comment solicited, before being issued as a final permit. The Statement of Basis for the draft UPDES permit will contain information on how the ADR was addressed including results of the Level I and Level II reviews. In the case of Section 404 permits from the Corps of Engineers, the Division of Water Quality will develop any needed 401 Certifications and the public notice may be published in conjunction with the US Corps of Engineers public notice procedures. Other permits requiring a Level II review will receive a separate public notice according to the normal State public notice procedures. The public will be provided notice and an opportunity to comment whenever substantive changes are made to the implementation procedures referenced in Subsection R317-2-3.5.f. f. Implementation Procedures The Director shall establish reasonable protocols and guidelines (1) for completing technical, social, and economic need demonstrations, (2) for review and determination of adequacy of Level II ADRs and (3) for determination of additional treatment requirements. Protocols and guidelines will consider federal guidance and will include input from local governments, the regulated community, and the general public. The Director will inform the Water Quality Board of any protocols or guidelines that are developed. |

| R317-2-5. Mixing Zones |
|
Latest version.
|
|
A mixing zone is a limited portion of a body of water, contiguous to a discharge, where dilution is in progress but has not yet resulted in concentrations which will meet certain standards for all pollutants. At no time, however, shall concentrations within the mixing zone be allowed which are acutely lethal as determined by bioassay or other approved procedure. Mixing zones may be delineated for the purpose of guiding sample collection procedures and to determine permitted effluent limits. The size of the chronic mixing zone in rivers and streams shall not to exceed 2500 feet and the size of an acute mixing zone shall not exceed 50% of stream width nor have a residency time of greater than 15 minutes. Streams with a flow equal to or less than twice the flow of a point source discharge may be considered to be totally mixed. The size of the chronic mixing zone in lakes and reservoirs shall not exceed 200 feet and the size of an acute mixing zone shall not exceed 35 feet. Domestic wastewater effluents discharged to mixing zones shall meet effluent requirements specified in R317-1-3. 5.1 Individual Mixing Zones. Individual mixing zones may be further limited or disallowed in consideration of the following factors in the area affected by the discharge: a. Bioaccumulation in fish tissues or wildlife, b. Biologically important areas such as fish spawning/nursery areas or segments with occurrences of federally listed threatened or endangered species, c. Potential human exposure to pollutants resulting from drinking water or recreational activities, d. Attraction of aquatic life to the effluent plume, where toxicity to the aquatic life is occurring. e. Toxicity of the substance discharged, f. Zone of passage for migrating fish or other species (including access to tributaries), or g. Accumulative effects of multiple discharges and mixing zones. |

7.1 Application of Standards a. The numeric criteria listed in R317-2-14 shall apply to each of the classes assigned to waters of the State as specified in R317-2-6. It shall be unlawful and a violation of these rules for any person to discharge or place any wastes or other substances in such manner as may interfere with designated uses protected by assigned classes or to cause any of the applicable standards to be violated, except as provided in R317-1-3.1. b. At a minimum, assessment of the beneficial use support for waters of the state will be conducted biennially and available for a 30-day period of public comment and review. Monitoring locations and target indicators of water quality standards shall be prioritized and published yearly. For water quality assessment purposes, up to 10 percent of the representative samples may exceed the minimum or maximum criteria for dissolved oxygen, pH, E. coli, total dissolved solids, and temperature, including situations where such criteria have been adopted on a site-specific basis. c. Site-specific standards may be adopted by rulemaking where biomonitoring data, bioassays, or other scientific analyses indicate that the statewide criterion is over or under protective of the designated uses or where natural or un-alterable conditions or other factors as defined in 40 CFR 131.10(g) prevent the attainment of the statewide criteria as prescribed in Subsections R317-2-7.2, and R317-2-7.3, and Section R317-2-14. 7.2 Narrative Standards It shall be unlawful, and a violation of these rules, for any person 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 bioassay or other tests performed in accordance with standard procedures; or determined by biological assessments in Subsection R317-2-7.3. 7.3 Biological Water Quality Assessment and Criteria Waters of the State shall be free from human-induced stressors which will degrade the beneficial uses as prescribed by the biological assessment processes and biological criteria set forth below: a. Quantitative biological assessments may be used to assess whether the purposes and designated uses identified in R317-2-6 are supported. b. The results of the quantitative biological assessments may be used for purposes of water quality assessment, including, but not limited to, those assessments required by 303(d) and 305(b) of the federal Clean Water Act (33 U.S.C. 1313(d) and 1315(b)). c. Quantitative biological assessments shall use documented methods that have been subject to technical review and produce consistent, objective and repeatable results that account for methodological uncertainty and natural environmental variability. d. If biological assessments reveal a biologically degraded water body, specific pollutants responsible for the degradation will not be formally published (i.e., Biennial Integrated Report, TMDL) until a thorough evaluation of potential causes, including nonchemical stressors (e.g., habitat degradation or hydrological modification or criteria described in 40 CFR 131.10 (g)(1 - 6) as defined by the Use Attainability Analysis process), has been conducted. |

(2) The dissolved metals method involves filtration of the sample in the field, acidification of the sample in the field, no digestion process in the laboratory, and analysis by approved laboratory methods for the required detection levels. (3) Reserved (4) SITE SPECIFIC STANDARDS FOR TOTAL DISSOLVED SOLIDS (TDS) Blue Creek and tributaries, Box Elder County, from Bear River Bay, Great Salt Lake to Blue Creek Reservoir: March through October daily maximum 4,900 mg/l and an average of 3,800 mg/l; November through February daily maximum 6,300 mg/l and an average of 4,700 mg/l. Assessments will be based on TDS concentrations measured at the location of STORET 4960740. Blue Creek Reservoir and tributaries, Box Elder County, daily maximum 2,100 mg/l; Castle Creek from confluence with the Colorado River to Seventh Day Adventist Diversion: 1,800 mg/l; Cottonwood Creek from the confluence with Huntington Creek to Highway U-57: 3,500 mg/l; Ferron Creek from the confluence with San Rafael River to Highway U-10: 3,500 mg/l; Huntington Creek and tributaries from the confluence with Cottonwood Creek to Highway U-10: 4,800 mg/l; Ivie Creek and its tributaries from the confluence with Muddy Creek to the confluence with Quitchupah Creek: 3,800 mg/l provided that total sulfate not exceed 2,000 mg/l to protect the livestock watering agricultural existing use; Ivie Creek and its tributaries from the confluence with Quitchupah Creek to Highway U-10: 2,600 mg/l; Lost Creek from the confluence with Sevier River to U.S. National Forest boundary: 4,600 mg/l; Muddy Creek and tributaries from the confluence with Ivie Creek to Highway U-10: 2,600 mg/l; Muddy Creek from confluence with Fremont River to confluence with Ivie Creek: 5,800 mg/l; North Creek from the confluence with Virgin River to headwaters: 2,035 mg/l; Onion Creek from the confluence with Colorado River to road crossing above Stinking Springs: 3000 mg/l; Brine Creek-Petersen Creek, from the confluence with the Sevier River to Highway U-119 Crossing: 9,700 mg/l; Price River and tributaries from confluence with Green River to confluence with Soldier Creek: 3,000 mg/l; Price River and tributaries from the confluence with Soldier Creek to Carbon Canal Diversion: 1,700 mg/l; Quitchupah Creek and tributaries from the confluence with Ivie Creek to Highway U-10: 3,800 mg/l provided that total sulfate not exceed 2,000 mg/l to protect the livestock watering agricultural existing use; Rock Canyon Creek from the confluence with Cottonwood Creek to headwaters: 3,500 mg/l; San Pitch River from below Gunnison Reservoir to the Sevier River: 2,400 mg/l; San Rafael River from the confluence with the Green River to Buckhorn Crossing: 4,100 mg/l; San Rafael River from the Buckhorn Crossing to the confluence with Huntington Creek and Cottonwood Creek: 3,500 mg/l; Sevier River between Gunnison Bend Reservoir and DMAD Reservoir: 1,725 mg/l; Sevier River from Gunnison Bend Reservoir to Crafts Lake: 3,370 mg/l; Silver Creek and tributaries, Summit County, from confluence with Tollgate Creek to headwaters: maximum 1,900 mg/L. South Fork Spring Creek from confluence with Pelican Pond Slough Stream to U.S. Highway 89 1,450 mg/l (Apr.-Sept.) 1,950 mg/l (Oct.-March) Virgin River from the Utah/Arizona border to Pah Tempe Springs: 2,360 mg/l (5) Investigations should be conducted to develop more information where these pollution indicator levels are exceeded. These indicators are superseded by numeric criteria in waters where promulgated. (6) Total Phosphorus as P (mg/l) indicator for lakes and reservoirs shall be 0.025. (7) Where the criteria are exceeded and there is a reasonable basis for concluding that the indicator bacteria E. coli are primarily from natural sources (wildlife), e.g., in National Wildlife Refuges and State Waterfowl Management Areas, the criteria may be considered attained provided the density attributable to non-wildlife sources is less than the criteria. Exceedences of E. coli from nonhuman nonpoint sources will generally be addressed through appropriate Federal, State, and local nonpoint source programs. Measurement of E. coli using the "Quanti-Tray 2000" procedure is approved as a field analysis. Other EPA approved methods may also be used. For water quality assessment purposes, up to 10% of representative samples may exceed the 668 per 100 ml criterion (for 1C and 2B waters) and 409 per 100 ml (for 2A waters). For small datasets, where exceedences of these criteria are observed, follow-up ambient monitoring should be conducted to better characterize water quality.

(2) These limits are not applicable to lower water levels in deep impoundments. First number in column is for when early life stages are present, second number is for when all other life stages present. (2a) These criteria are not applicable to Great Salt Lake impounded wetlands. Surface water in these wetlands shall be protected from changes in pH and dissolved oxygen that create significant adverse impacts to the existing beneficial uses. To ensure protection of uses, the Director shall develop reasonable protocols and guidelines that quantify the physical, chemical, and biological integrity of these waters. These protocols and guidelines will include input from local governments, the regulated community, and the general public. The Director will inform the Water Quality Board of any protocols or guidelines that are developed. (3) Site Specific Standards for Temperature Kens Lake: From June 1st - September 20th, 27 degrees C. (4) Where criteria are listed as 4-day average and 1-hour average concentrations, these concentrations should not be exceeded more often than once every three years on the average. (5) The dissolved metals method involves filtration of the sample in the field, acidification of the sample in the field, no digestion process in the laboratory, and analysis by EPA approved laboratory methods for the required detection levels. (6) The criterion for aluminum will be implemented as follows: Where the pH is equal to or greater than 7.0 and the hardness is equal to or greater than 50 ppm as CaC03 in the receiving water after mixing, the 87 ug/1 chronic criterion (expressed as total recoverable) will not apply, and aluminum will be regulated based on compliance with the 750 ug/1 acute aluminum criterion (expressed as total recoverable). (7) Hardness dependent criteria. 100 mg/l used. Conversion factors for ratio of total recoverable metals to dissolved metals must also be applied. In waters with a hardness greater than 400 mg/l as CaC03, calculations will assume a hardness of 400 mg/l as CaC03. See Table 2.14.3 for complete equations for hardness and conversion factors. (8) See also numeric criteria for organism only in Table 2.14.6. (9) The following equations are used to calculate Ammonia criteria concentrations: (9a) The thirty-day average concentration of total ammonia nitrogen (in mg/l as N) does not exceed, more than once every three years on the average, the chronic criterion calculated using the following equations. Fish Early Life Stages are Present: mg/l as N (Chronic) = ((0.0577/(1+107.688-pH)) + (2.487/(1+ 10pH-7.688))) * MIN (2.85, 1.45*100.028*(25-T)) Fish Early Life Stages are Absent: mg/1 as N (Chronic) = ((0.0577/(1+107.688-pH)) + (2.487/ (1+10pH-7.688))) * 1.45*100.028* (25-MAX(T,7))) Mill Creek (Salt Lake County) from confluence with Jordan River to Interstate 15, Jordan River from 900 South Street to confluence with Mill Creek, Surplus Canal from 900 South Street to diversion from the Jordan River, Fish Early Life Stages are Present: mg/l as N (Chronic) = 0.9405 * ((0.0278/(1+107.688-pH)) + ((1.1994/(1+10pH-7.688))) * MIN(6.920,(7.547*100.028*(20-T)))) Mill Creek (Salt Lake County) from confluence with Jordan River to Interstate 15, Jordan River from 900 South Street to confluence with Mill Creek, Surplus Canal from 900 South Street to diversion from the Jordan River, Fish Early Life Stages are Absent: mg/L as N (chronic) = 09.405 * (((0.0278/(1+107.688-pH)) + (1.1994/(1+10pH-7.688))) * (7.547*100.028*(20-MAX (T,7))) (9b) The one-hour average concentration of total ammonia nitrogen (in mg/l as N) does not exceed, more than once every three years on the average the acute criterion calculated using the following equations. Class 3A: mg/l as N (Acute) = (0.275/(1+107.204-pH)) + (39.0/1+10pH-7.204)) Class 3B, 3C, 3D: mg/l as N (Acute) = 0.411/(1+107.204-pH)) + (58.4/(1+10pH-7.204)) Mill Creek (Salt Lake County) from confluence with Jordan River to Interstate 15, Jordan River from 900 South Street to confluence with Mill Creek, Surplus Canal from 900 South Street to diversion from the Jordan River: mg/l as N (Acute) = 0.729 * (((0.0114/(1+107.204-pH))+(1.6181/ (1+10pH-7.204))) * MIN(51.93,(62.15*100.036*(20-T))) In addition, the highest four-day average within the 30-day period should not exceed 2.5 times the chronic criterion. The "Fish Early Life Stages are Present" 30-day average total ammonia criterion will be applied by default unless it is determined by the Director, on a site-specific basis, that it is appropriate to apply the "Fish Early Life Stages are Absent" 30-day average criterion for all or some portion of the year. At a minimum, the "Fish Early Life Stages are Present" criterion will apply from the beginning of spawning through the end of the early life stages. Early life stages include the pre-hatch embryonic stage, the post-hatch free embryo or yolk-sac fry stage, and the larval stage for the species of fish expected to occur at the site. The Director will consult with the Division of Wildlife Resources in making such determinations. The Division will maintain information regarding the waterbodies and time periods where application of the "Early Life Stages are Absent" criterion is determined to be appropriate. (10) Investigation should be conducted to develop more information where these levels are exceeded. (11) pH dependent criteria. pH 7.8 used in table. See Table 2.14.4 for equation. (12) Total Phosphorus as P (mg/l) as a pollution indicator for lakes and reservoirs shall be 0.025. These indicators are superseded by numeric criteria in waters where promulgated. (13) Reserved (14) The selenium water quality standard of 12.5 (mg/kg dry weight) for Gilbert Bay is a tissue based standard using the complete egg/embryo of aquatic dependent birds using Gilbert Bay based upon a minimum of five samples over the nesting season. Assessment procedures are incorporated as a part of this standard as follows: Egg Concentration Triggers: DWQ Responses Below 5.0 mg/kg: Routine monitoring with sufficient intensity to determine if selenium concentrations within the Great Salt Lake ecosystem are increasing. 5.0 mg/kg: Increased monitoring to address data gaps, loadings, and areas of uncertainty identified from initial Great Salt Lake selenium studies. 6.4 mg/kg: Initiation of a Level II Antidegradation review by the State for all discharge permit renewals or new discharge permits to Great Salt Lake. The Level II Antidegradation review may include an analysis of loading reductions. 9.8 mg/kg: Initiation of preliminary TMDL studies to evaluate selenium loading sources. 12.5 mg/kg and above: Declare impairment. Formalize and implement TMDL. Antidegradation Level II Review procedures associated with this standard are referenced at R317-2-3.5.C.
