RULE ANALYSIS
Purpose of the rule or reason for the change:
In accordance with Subsection R317-1-2.2(C), the three-year review of Rule R317-2 was conducted. These changes are the result of that review that included input from the public. The proposed changes are to resolve USEPA disapprovals, adopt updated water quality criteria, provide greater flexibility for developing site-specific standards, and make editorial corrections.
Summary of the rule or change:
In Subsections R317-2-3(3.2) and (3.3), Federal rules allow degradation in Tier 3 waters for discharges that are temporary and limited. Utah included this exemption for existing Category 1 waters with roads being listed as a specific example. The road example was deleted and a reference to the criteria to be considered for making a temporary and limited determination was added. Road construction and other activities that meets the criteria for temporary and limited will continue to be allowed. In addition, this same exemption was added to the less stringent, existing Category 2 waters (proposed Category 3). In Subsection R317-2-3(3.5)(b)(1)(d), this example for when an antidegradation review is not required was deleted to resolve a USEPA disapproval in 2010. In Section R317-2-4, the 2011 review is complete and the agreement is updated in Utah's Standards as shown below. In Subsection R317-2-7(7.1), Tables 2.14.1 and 2.14.2 - this section regarding numeric standards was revised to acknowledge that numeric standards can be modified based on certain site-specific conditions. The previous version of the standards listed changes based on bioassays or other methods, and site-specific temperature and total dissolved solids standards based on natural conditions. This change consolidates and broadens the reasons for allowing site-specific standards consistent with USEPA policies and the Clean Water Act. Footnote (4) from Table 2.14.1 was moved to Subsection R317-2-7(7.1) and Footnote (3) from Table 2.14.2 was deleted but site-specific temperature can be developed per the revised Subsection R317-2-7(7.1). The Water Quality Board must approve any change to the Standards thereby preserving their approval role. In Subsections R317-2-12(12.1)(a) and R317-2-12(12.2)(a), this reach of the Weber River was mistakenly moved to Subsection R317-2-12(12.2) during the Standards changes in 2010 (see the proposed amendment to Rule R317-2 under DAR No. 33233 in the December 15, 2009, issue of the Bulletin, p. 45 and the corresponding change in proposed rule to Rule R317-2 under DAR No. 33233 in the February 15, 2010, issue of the Bulletin, p. 68. Both were made effective on 04/01/2010). This change inadvertently changed the Category of this reach from existing Category 3 to existing Category 2 and this correction restores the original classifications. In Subsection R317-2-12(12.1)(b)(6), US 189 was the previous boundary for existing Category 1 waters Chalk Creek and the Weber River. With the construction of Jordanelle Reservoir, US 189 was rerouted and is no longer a valid boundary. The boundary for the existing Category 1 waters was updated to reflect the previous geographic boundary with existing roads. The protection status of Chalk Creek and the Weber river are unchanged. In Subsection R317-2-13(13.1), the Fremont River and tributaries, through Capitol Reef National Park to headwaters were changed from Class 2B (infrequent primary and secondary contact recreation) to Class 2A (frequent primary and secondary contact recreation) based on information and the pictures below provided by the U.S. Park Service. Frequent primary recreation has more stringent numeric standards than infrequent primary recreation. In Subsection R317-2-13(13.4)(a), the Ogden River and tributaries, from confluence with Weber River to Pineview Dam, except as listed below to Class 2A (frequent primary and secondary contact recreation) from Class 2B (infrequent primary and secondary contact recreation). Frequent primary recreation has more stringent numeric standards than infrequent primary recreation and one of the goals of the Ogden River restoration is to encourage recreation. Ms. Kari Lundeen, DWQ Watershed Coordinator, reported that people regularly swim in this reach of the Ogden River. In Subsection R317-2-13(13.5)(a), assign beneficial uses of 2B, 3A, and 4 to Red Butte Creek and tributaries from Liberty Park pond inlet to Red Butte Reservoir. In Subsection R317-2-13(13.5)(a), assign beneficial uses of 2B, 3A, to Emigration Creek Emigration Creek and tributaries, from 1100 East in Salt Lake City to headwaters. This changes the boundary from Foothill Boulevard to 1100 East. In addition, add the beneficial use of Class 4 (agriculture) to protect the water rights for irrigation. In Subsections R317-2-13(13.2)(a) and R317-2-13(13.2)(bb), delete "**" that referred to a site-specific temperature standard. No site-specific temperature standard has been was promulgated for Hyrum or Pineview Reservoirs in Subsection R317-2-13(13.2)(x), add beneficial uses of 2B (infrequent primary and secondary contact recreation, 3A (cold water aquatic life), and 4 (agriculture) to Big East Lake. In Subsection R317-2-13(13.2), assign beneficial uses of 1C (drinking water), 2A (frequent primary and secondary recreation contact), 3B (warm water aquatic life), and 4 (agriculture). In Subsection R317-2-13(13.2), delete Class 2B (infrequent primary recreation) where water is also Class 2A (frequent primary recreation because the numeric standards for 2A are more stringent than 2B. Class 2B was deleted from: Bear Lake, Deer Creek, East Canyon, Echo, Flaming Gorge, Gunlock, Huntington Lake North, Hyrum, Lyman, Joe's Valley, Millsite, Moon, Palisades, Pineview, Powell, Pyramid, Quail Creek, Redfleet, Rockport, Scout, Starvation, Steinaker, and Yuba. This change does not affect the level of protection for these waters. In Table 2.14.1, Site-Specific TDS Standards, Price River - change the boundary of the 3,000/1,700 mg/l site-specific TDS standard from Coal Creek to Soldier Creek. In Table 2.14.2, delete acute criteria for mercury. In Table 2.14.2, add numeric criteria for tributyl tin. In Tables 2.14.2 and 2.14.7, add numeric criteria for acrolein. In Table 2.14.2, add numeric criteria for chlorpyrifos. In Table 2.14.6, revise numeric criteria for phenol.
State statutory or constitutional authorization for this rule:
- Section 19-5-105
Anticipated cost or savings to:
the state budget:
No additional costs or savings to state budget are anticipated. The proposed amendments will be addressed using existing resources.
local governments:
No additional costs are anticipated because the more stringent numeric criteria will not affect existing UDPES permits. The provisions for site-specific standards will potentially reduce costs.
small businesses:
No additional costs or savings to small businesses are anticipated because the more stringent numeric criteria will not affect existing UDPES permits.
persons other than small businesses, businesses, or local governmental entities:
No additional costs to other persons are anticipated because the more stringent numeric criteria will not affect existing UDPES permits. The provisions for site-specific standards will potentially reduce costs.
Compliance costs for affected persons:
Compliance costs are anticipated to remain the same because the more stringent numeric criteria will not affect existing UDPES permits.
Comments by the department head on the fiscal impact the rule may have on businesses:
Compliance costs are anticipated to remain the same for the USEPA mandated adoption of more stringent water quality criteria because current permitted facilities will meet the new standards. Compliance costs will be less when the site-specific option allowed by the proposed changes is used.

RULE TEXT
R317. Environmental Quality, Water Quality.
R317-2. Standards of Quality for Waters of the State.
. . . . . . .
R317-2-3. Antidegradation Policy.
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 Board, 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 Regulations 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.
[Projects such as, but not limited to, construction of dams
or roads will be considered]Discharges may be allowed where pollution will [result only during the actual construction
activity]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 Executive Secretary 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
[
(d) a new or renewed UPDES permit is being issued, and
water quality-based effluent limits are not required for a specific
pollutant because it has been determined that the discharge will
not cause, have reasonable potential to cause, or contribute to an
exceedance of a State water quality standard for the
pollutant.
] 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 permits, CWA Section 404 nationwide and 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. The 404 nationwide permits decision will be made at the time of permit issuance, as part of the Division's water quality certification under CWA Section 401. Where it is determined that the category of activities will result in temporary and limited effects, subsequent individual activities authorized under such permits will not be subject to further antidegradation review. 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 Division of Water Quality 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 Executive Secretary 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 Executive Secretary 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. Special Procedures for 404 Permits.
For 404 permitted activities, all appropriate alternatives to avoid and minimize degradation should be evaluated. Activities involving a discharge of dredged or fill materials that are considered to have more than minor adverse affects on the aquatic environment are regulated by individual CWA Section 404 permits. The decision-making process relative to the 404 permitting program is contained in the 404(b)(1) guidelines (40 CFR Part 230). Prior to issuing a permit under the 404(b)(1) guidelines, the Corps of Engineers:
(a) makes a determination that the proposed activity discharges are unavoidable (i.e., necessary):
(b) examines alternatives to the proposed activity and authorize only the least damaging practicable alternative; and
(c) requires mitigation for all impacts associated with the activity. A 404(b)(1) finding document is produced as a result of this procedure and is the basis for the permit decision. Public participation is provided for in the process. Because the 404(b)(1) guidelines contains an alternatives analysis, the executive secretary will not require development of a separate alternatives analysis for the anti-degradation review. The division will use the analysis in the 404(b)(1) finding document in completing its anti-degradation review and 401 certification.
4. 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.
5. 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 Executive Secretary to authorize proposed activities that would otherwise not be authorized.
6. 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.
7. 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.
8. 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 Division 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
An Antidegradation Level II Review will be required by the Executive Secretary for discharges to waters with a Class 1C drinking water use assigned.
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 Executive Secretary 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 Executive Secretary 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. Where possible, public notice on the antidegradation review conclusions will be combined with the public notice on the proposed permitting 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 will 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.
f. Implementation Procedures
The Executive Secretary 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 Executive Secretary will inform the Water Quality Board of any protocols or guidelines that are developed.
R317-2-4. Colorado River Salinity Standards.
In addition to quality protection afforded
by these regulations to waters of the Colorado River and its
tributaries, such waters shall be protected also by requirements of
"Proposed Water Quality Standards for Salinity including
Numeric Criteria and Plan of Implementation for Salinity Control,
Colorado River System, June 1975" and a supplement dated
August 26, 1975, entitled "Supplement, including Modifications
to Proposed Water Quality Standards for Salinity including Numeric
Criteria and Plan of Implementation for Salinity Control, Colorado
River System, June 1975", as approved by the seven Colorado
River Basin States and the U.S. Environmental Protection Agency, as
updated by the 1978 Revision and the 1981, 1984, 1987, 1990, 1993,
1996, 1999, 2002, 2005, [and] 2008
, and 2011 [R]reviews of the above documents.
. . . . . . .
R317-2-7. Water Quality Standards.
7.1 Application of Standards
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 regulations 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. 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. [The Board may allow site specific modifications based upon
bioassay or other tests performed in accordance with standard
procedures determined by the Board.]Site-specific criterion 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 criterion.
7.2 Narrative Standards
It shall be unlawful, and a violation of these regulations, 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.

be adopted by rulemaking where it is demonstrated that: (a) a
less stringent criterion is appropriate because of natural or
un-alterable conditions; or (b) a less stringent, site-specific
criterion and/or date-specified criterion is protective of
existing and attainable agricultural uses; or (c) a more
stringent criterion is attainable and necessary for the
protection of sensitive crops.
For water quality assessment purposes, up to 10% of
representative samples may exceed the standard.

(5) Investigations should be conducted to develop more
information where these pollution indicator levels are exceeded.
(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.

FOOTNOTES:
(1) Not to exceed 110% of saturation.
(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 Executive Secretary 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 Executive Secretary will inform the Water
Quality Board of any protocols or guidelines that are developed.
(3) [The temperature standard shall be at background where]
it can be shown that natural or un-alterable conditions
prevent its attainment. In such cases rulemaking will be
undertaken to modify the standard accordingly.
Site Specific Standards for Temperature
Ken's Lake: From June 1 st - September 20 th, 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) Reserved
(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+10 7.688-pH)) + (2.487/(1+
10 pH-7.688))) * MIN (2.85, 1.45*10 0.028*(25-T) )
Fish Early Life Stages are Absent:
mg/1 as N (Chronic) = ((0.0577/(1+10 7.688-pH)) + (2.487/
(1+10 pH-7.688)))
* 1.45*10 0.028* (25-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+10 7.204-pH)) + (39.0/1+10 pH-7.204))
Class 3B, 3C, 3D:
mg/l as N (Acute) = 0.411/(1+10 7.204-pH)) + (58.4/(1+10 pH-7.204))
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 Division, 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 division
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.
(13) Formula to convert dissolved sulfide to un-disassociated
hydrogen sulfide is: H 2S = Dissolved Sulfide * e ((-1.92 + pH) + 12.05)
(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.
