RULE ANALYSIS
Purpose of the rule or reason for the change:
This rule is being changed to update formatting; correct errors; add a potable water designated use to Sheep Creek requested by a homeowners association; revise the total dissolved solids criterion for Silver Creek to resolve the existing water quality impairment; update the aquatic life ammonia criteria for a section of the Jordan River to be less stringent; provide flexibility for field methods in Section R317-2-10; and apply nutrient criteria to specific Category 1 and Category 2 waters to protect the recreational and aquatic life uses.
Summary of the rule or change:
LABORATORY AND FIELD ANALYSES: In Section R317-2-10, a clause was added to provide flexibility of field methods that are different than Division of Water Quality standard procedures. SHEEP CREEK USE CHANGE: The Class 1C designated use (drinking water source) was applied to Sheep Creek, Cache County based on a request from a homeowners association and the Utah Division of Drinking Water. SILVER CREEK TDS CRITERION: The total dissolved solids (TDS) criterion was revised for upper Silver Creek in Summit County from 1,200 mg/L to 1,900 mg/L in Table 2.14.1. JORDAN RIVER AMMONIA CRITERIA: The aquatic life criteria for ammonia for segments of the Jordan River, Surplus Canal, and Mill Creek, Salt Lake County were changed based on updated information regarding the toxicity of ammonia and studies characterizing the aquatic life in these segments in Table 2.14.2. NUTRIENT CRITERIA: In Section R317-2-14 (Numeric Criteria), new Table 2.14.7 was added for nutrient criteria applicable to Antidegradation Category 1 and 2 waters statewide. These criteria are needed to ensure that Utah's headwaters continue to deliver high quality water to, for instance, drinking water. Nitrogen and phosphorus (nutrients) criteria were developed and applied to Category 1 and Category 2 waters in new Tables 2.14.7 and 2.14.8. UPDATES AND CORRECTIONS: In Section R317-2-14, Tables 2.14.1 and 2.14.6, several corrections were made to the statewide human health criteria. The aquatic life cadmium chronic criterion formula was corrected. The corrections to Tables 2.14.1, 2.14.2 and 2.14.6 were because the 2018 revisions (Utah State Bulletin, No. 2018-7, April 1, 2018, Filing No. 42691) were not implemented as intended.
Statutory or constitutional authorization for this rule:
- 40 CFR Part 131
- Title 19, Chapter 5
This rule or change incorporates by reference the following material:
- Adds Table 8, Decision Matrix That Will Be Used to Assess Support of Headwater Aquatic Life Uses for Nutrient-related Water Quality Problems, "Proposed Nutrient Criteria: Utah Headwater Streams", published by Utah Division of Water Quality, 03/01/2019
Anticipated cost or savings to:
the state budget:
SUMMARY: No direct costs will be incurred by state agencies because no state agency is a constrained party. The Utah Division of Water Quality will incur indirect costs that are estimated to be a one-time cost of $6,400 and aggregate annual costs of $4,500 over the next 3 years ($8,000/year of increased costs associated with nutrient criteria monitoring offset by $6,500/year of cost savings associated with reduced monitoring on Silver Creek). These costs will be absorbed through agency process efficiencies. LABORATORY AND FIELD ANALYSES: The proposed revision to Section R317-2-10 Laboratory and Field Analyses is cost neutral or will cause indirect costs for state agencies. The indirect costs would be to the Division of Water Quality for the staff time required to review the alternative methods allowed by the proposed revision. The indirect costs are inestimable because no data is available regarding how many alternative methods may be proposed by entities external to the Division of Water Quality. Currently, this type of request is infrequent but is estimated to require 120 hours of staff time at $100/hr for review should any methods be submitted for approval. No requests are anticipated over the next three years. SHEEP CREEK USE CHANGE: The addition of the Class 1C use to Sheep Creek is cost neutral because no additional resources are required for its implementation. SILVER CREEK TDS CRITERION: The proposed TDS criterion for upper Silver Creek will result in ongoing indirect benefits of $6,500 annually for the Utah Division of Water Quality, which is deducted from annual costs for purposes of overall evaluation of these proposed changes to this rule. These savings are based on the resolution of the existing TDS water quality impairment and an elimination of 8 sampling trips per year, 8 hours per trip specifically for TDS measurements, at $100/hr. JORDAN RIVER AMMONIA CRITERIA: The proposed ammonia criteria for segments of the Jordan River, Surplus Canal, and Mill Creek are cost neutral because no additional resources will be required for their implementation. NUTRIENT CRITERIA: The proposed nutrient criteria in Section R317-2-14 will result in net one-time and ongoing indirect costs to the Division of Water Quality. The one-time costs will be to update the use classifications and criteria in various internal systems. The one-time indirect fiscal impacts will be $1,400 assuming four hours to update each of the four databases at $100/hr and $5,000 for 5 new probes to measure ecosystem respiration and gross primary production. Anticipated ongoing indirect costs are for the implementation of new sampling and analysis methods to support assessment of the proposed nutrient criteria and are estimated to be $24,000 over the next 3 years ($8,000/year). The nutrient criteria require new measures of gross primary production, ecosystem respiration and filamentous algae. Costs are dependent on the number of sites sampled which depends on the available existing resources. Additional labor costs associated with the collection of requisite data is estimated based on an average of 40 site visits and an additional 0.5 hourS for a field crew of 2 on each visitation; and 4 hours for one staff for calculating and processing the gross primary production and ecosystem respiration data for approximately 10 sites annually, resulting in an annual expense of approximately $8,000. If water quality impairments are identified by the nutrient criteria, the Division of Water Quality will incur inestimable indirect costs to further investigate and if appropriate, restore the impaired water quality. Long term costs to the Division of Water Quality to address nutrient-related impairments are also inestimable because actions taken are situational and often deferred by state or federal grants. The proposed nutrient criteria in Section R317-2-14 may result in indirect inestimable costs to state of Utah land management agencies. These agencies are not constrained parties, but water quality nutrient impairments could potentially result in increased costs associated with nutrient management. However, these impacts are unlikely to be significant because the affected activities have to occur in an area co-located with an impaired stream and have been demonstrated to be contributing to the impairment as a source of nitrogen or phosphorus to the stream. Further, implementation measures to address nonpoint sources of pollution are voluntary and are often offset by state and federal nonpoint source grants. New impairments resulting from the proposed nutrient criteria are not anticipated over the next three years, because the Division of Water Quality has a biannual reporting cycle for making impairment determinations, with the first report relevant to these criteria planned for 2022. Plans to restore impairments cannot be developed or implemented until impaired waters are identified. As a result, immediate costs associated with new impairments are anticipated to be neutral, exceptions being inestimable. Once impairment decisions are ultimately made, additional indirect costs are inestimable, but likely to be relatively small in size and scope. Based on currently available data, approximately 10-15% of the affected streams may ultimately be classified as impaired, meaning water quality does not meet the proposed nutrient criteria, but these estimates are statistical and additional indirect expense increases, if any, are expected to vary considerably on a case-by-case basis. Even for potentially affected activities that are co-located on an impaired stream, increased indirect costs are not inevitable. Impairment determinations trigger additional investigations that are conducted by the Utah Division of Water Quality or other interested parties. Only after the additional investigations, is a final determination made regarding impairment and sources of nutrient pollution. For those activities ultimately found to be contributing to a nutrient-related impairment as a source of nitrogen and phosphorus, costs are inestimable because there are generally many ways that their contribution to the impairment can be resolved, some of which may be revenue neutral. Given the relatively small number of anticipated impairments and the voluntary nature of implementation measures, the proposed nutrient criteria will be revenue neutral. UPDATES AND CORRECTIONS: There are no costs or benefits associated with the remaining updates and corrections to Section R317-2-14.
local governments:
SUMMARY: The impact of these proposed changes on local governments are inestimable benefits. LABORATORY AND FIELD ANALYSES: Local governments are not constrained parties for the proposed revision to Section R317-2-10 because local governments are not required to conduct field analyses. For indirect effects to local governments, the proposed revision is cost neutral or will have inestimable benefits. The proposed revision provides optional flexibility on acceptable analytical methods that the Division of Water Quality is willing to use to interpret water quality regulations. Presumably, local governments will only exercise this option to submit alternative methods for agency approval if it is cost neutral or a benefit. No data is available to estimate the frequency or specifics of these potential requests. SHEEP CREEK USE CHANGE: The impacts are neutral for the addition of the Class 1C use to Sheep Creek in Section R317-2-13 because no local governments are constrained or affected. SILVER CREEK TDS CRITERION: The Snyderville Basin Water Reclamation District (District) and Park City are the constrained parties for the proposed site-specific TDS criterion. The proposed TDS criterion is less stringent than the existing criterion and will result in benefits that are inestimable. Under the existing TDS criterion, additional treatment to comply was estimated by the District to be $120,873,000 in capital costs and $2,710,000 for annual operating costs using 2013 dollars. The estimates did not include disposal of the brine waste that would be generated by the treatment process which is expected to be a significant additional cost. These treatment cost estimates are expected to meet the threshold that would cause widespread social and economic harm for compliance. Treatment is not required above this social and economic harm threshold under either federal or Utah requirements. The actual realized benefits are inestimable because the economic analyses are unavailable to calculate an accurate cost savings; that is, based on avoiding economic harm, how much the District would have had to spend for compliance; but the proposed changes would result in considerable savings to the District. The impacts to the other constrained party, Park City, are neutral because their permitted discharges are below the existing TDS criterion and are unaffected by the change in rule. JORDAN RIVER AMMONIA CRITERIA: The Central Valley Water Reclamation Facility (CVWRF) is the only constrained local government affected by the Jordan River, Surplus Canal, and Mill Creek ammonia criteria in Section R317-2-14. The proposed ammonia criteria are less stringent than the existing criteria and will result in inestimable compliance benefits. Less stringent criteria will result in less stringent effluent limits but ammonia effluent limits are also dependent on quantity of water available for dilution, ambient ammonia concentrations in the receiving waters, pH of the receiving waters, and temperature of the receiving waters. These other factors may result in higher or lower effluent limits but in all cases, the effluent limits will be less stringent than they would be under the existing ammonia criteria and under newly promulgated federal ammonia criteria. Over the next three years, the indirect cost impacts are anticipated to be neutral. However, under the less stringent proposed ammonia criteria, CVWRF anticipates delaying or avoiding significant future capital and operational costs that could be required for the treatment of ammonia compared to the existing ammonia criteria. For instance, capital costs for aeration tank and blower capacity expansion required to meet a lower ammonia criteria are estimated to be $10,000,000 to $15,000,000. NUTRIENT CRITERIA: Local governments are not constrained parties for the proposed nutrient criteria in Tables 2.14.7 and 2.14.8 because this rule does not apply to any stream that receives a municipal discharge. All 29 of Utah's counties include some Category 1 or Category 2 waters. Indirect impacts will be neutral or inestimable benefits. The inestimable indirect benefits are based on the potential future avoidance of additional treatment costs for drinking water or obtaining alternative sources of drinking water because of adverse nutrient-related impacts. Many nutrient-related effects have been demonstrated to have adverse impacts to recreation, so municipalities with economies that are heavily dependent on outdoor recreation may experience inestimable benefits if these rules prevent or diminish these problems. UPDATES AND CORRECTIONS: The proposed revisions to Table 2.14.6 are statewide, therefore publicly-owned treatment works are constrained parties. Local governments that operate sewer collection systems only, having no treatment works, may be indirectly affected. The impacts for both direct and indirect impacts are neutral because no local government currently has limits for these specific pollutants and this status is not expected to change.
small businesses:
SUMMARY: The impact of these proposed changes on small businesses are neutral or will result in inestimable costs. LABORATORY AND FIELD ANALYSES: Small businesses are not constrained parties for the proposed revision to Section R317-2-10 Laboratory and Field Analyses because small businesses are not required to conduct field analyses. For indirect effects to small businesses, the proposed revision is cost neutral or will have inestimable benefits. The proposed revision provides optional flexibility. Presumably, small businesses will only exercise these options if they are cost neutral or a benefit. No data is available to estimate the frequency or specifics of these potential requests. SHEEP CREEK USE CHANGE: The impacts are neutral for the addition of the Class 1C use to Sheep Creek in Section R317-2-13 because no small businesses are constrained or affected. SILVER CREEK TDS CRITERION: No small businesses are constrained by the proposed Silver Creek TDS criteria in Section R317-2-14 and direct effects are neutral because no small businesses have TDS effluent limits for the affected waters. Small businesses discharging to publically-owned treatment works may be affected indirectly if they discharge high levels of TDS. These indirect costs are inestimable because no small businesses currently have pretreatment limits for TDS. JORDAN RIVER AMMONIA CRITERIA: No small businesses are constrained by the proposed Jordan River ammonia criteria in Section R317-2-14 and direct effects are neutral because no small businesses have ammonia effluent limits for the affected waters. Small businesses discharging to CVWRF may be affected indirectly if they discharge high levels of ammonia. These indirect costs are inestimable because no small businesses currently discharging to CVWRF have pretreatment limits for ammonia. NUTRIENT CRITERIA: Small businesses are not constrained parties by the proposed nutrient criteria in Section R317-2-14. Small businesses could be impacted by indirect costs due to actions by federal or state land management agencies. These agencies grant leases and permits (hereafter in this section, permits refers to both) for small businesses to conduct activities such as recreation, oil and gas exploration and production, mining, timber harvesting, and grazing on state or federal lands. The land management agencies may elect to modify their leasing or permitting programs to implement best management practices (BMPs) if the activity is determined to cause or contribute to a nutrient impairment and these modifications may result in neutral impacts or increased indirect costs to the permittees. However, these impacts are unlikely to be significant because the affected permitted activities would have to occur in an area co-located with an impaired stream and have been demonstrated to be contributing to the impairment as a source of nitrogen or phosphorus to the stream. Further, implementation measures to address nonpoint sources of pollution are voluntary and are often offset by state and federal nonpoint source grants. New impairments resulting from the proposed nutrient criteria are not anticipated over the next three years, because the Division of Water Quality has a biannual reporting cycle for making impairment determinations, with the first report relevant to these criteria planned for 2022. Plans to restore impairments cannot be developed or implemented until impaired waters are identified. As a result, immediate costs associated with new impairments are anticipated to be neutral, exceptions being inestimable. Once impairment decisions are ultimately made, additional indirect costs to permittees are inestimable, but likely to be relatively small in size and scope. Based on currently available data, approximately 10-15% of the affected streams may ultimately be classified as impaired, defined as water quality not meeting the proposed nutrient criteria, but these estimates are statistical and additional indirect expense increases, if any, are expected to vary considerably on a case-by-case basis. Even for potentially affected permittees that are co-located on an impaired stream, increased indirect costs are not inevitable. Impairment determinations trigger additional investigations that are conducted by the Utah Division of Water Quality or other interested parties. Only after the additional investigations, is a final determination made regarding impairment and sources of nutrient pollution. For those permittees ultimately found to be contributing to a nutrient-related impairment as a source of nitrogen and phosphorus, costs are inestimable because there are generally many ways that their contribution to the impairment can be resolved, some of which may be revenue neutral. Costs for other remediation options are often offset through state and federal grants. Interested parties will generally evaluate all possible solutions when crafting restoration plans, and will attempt to select the most cost-effective solutions that are likely to lead to desired water quality improvements. Given the relatively small number of anticipated impairments and the voluntary nature of implementation measures, the proposed nutrient criteria are most likely to be revenue neutral. UPDATES AND CORRECTIONS: There are no costs or benefits associated with the remaining updates and corrections to Section R317-2-14.
persons other than small businesses, businesses, or local governmental entities:
SUMMARY: The impact of these proposed changes are neutral or will result in inestimable indirect costs for other persons. LABORATORY AND FIELD ANALYSES: Other persons are not constrained parties for the proposed revision to Section R317-2-10 Laboratory and Field Analyses because they are not required to conduct field analyses. SHEEP CREEK USE CHANGE: Indirect impacts are neutral or positive for the addition of the Class 1C use to Sheep Creek in Section R317-2-13 because no persons are constrained. The residents comprising the homeowners association that requested change may have indirect savings because of costs avoided for water treatment or for health care costs from ingesting contaminated drinking water. These indirect savings are inestimable because these are potential future savings since the affected waters currently meet the drinking water requirements. The indirect cost impacts will be neutral for the affected homeowners association that requested the change because the creek currently is meeting the Class 1C requirements. SILVER CREEK TDS CRITERION: The proposed TDS criterion for Silver Creek in Section R317-2-14 does not affect any other persons. JORDAN RIVER AMMONIA CRITERIA: The proposed ammonia criteria for the Jordan River in Section R317-2-14 do not affect any other persons. NUTRIENT CRITERIA: No constrained other persons are affected by the proposed nutrient criteria in Section R317-2-14. Other persons could be impacted by indirect costs due to actions by state or federal land management agencies. These agencies grant leases and permits (hereafter in this section, permits refers to both) for other persons to conduct activities such as recreation, oil and gas exploration and production, mining, timber harvesting, and grazing on state or federal lands. The land management agency may elect to modify their leasing or permitting programs to implement BMPs if the activity is determined to cause or contribute to a nutrient impairment and these modifications may result in neutral impacts or increased indirect costs to the permittees. However, these impacts are unlikely to be significant because the affected permitted activities would have to occur in an area co-located with an impaired stream and have been demonstrated to be contributing to the impairment as a source of nitrogen or phosphorus to the stream. Further, implementation measures to address nonpoint sources of pollution are voluntary and are often offset by state and federal nonpoint source grants. New impairments resulting from the proposed nutrient criteria are not anticipated over the next three years, because the Division of Water Quality has a biannual reporting cycle for making impairment determinations, with the first report relevant to these criteria planned for 2022. Plans to restore impairments cannot be developed or implemented until impaired waters are identified. As a result, immediate costs associated with new impairments are anticipated to be neutral, exceptions being inestimable. Once impairment decisions are ultimately made, additional indirect costs to permitted other persons are inestimable, but likely to be relatively small in size and scope. Based on currently available data, approximately 10-15% of the affected streams may ultimately be classified as impaired, meaning water quality is not meeting the proposed nutrient criteria, but these estimates are statistical and additional indirect expense increases, if any, are expected to vary considerably on a case-by-case basis. Even for potentially affected permitted persons that are co-located on an impaired stream, increased indirect costs are not inevitable. Impairment determinations trigger additional investigations that are conducted by the Utah Division of Water Quality or other interested parties. Only after the additional investigations, is a final determination made regarding impairment and sources of nutrient pollution. For those persons ultimately found to be contributing to a nutrient-related impairment as a source of nitrogen and phosphorus, costs are inestimable because there are generally many ways that their contribution to the impairment can be resolved, some of which may be revenue neutral. Costs of other remediation options with the potential to increase indirect costs are often offset through state and federal grants. Interested parties will generally evaluate all possible solutions when crafting restoration plans, and will attempt to select the most cost-effective solutions that are likely to lead to desired water quality improvements. Given the relatively small number of anticipated impairments and the voluntary nature of implementation measures, the proposed nutrient criteria are most likely to be revenue neutral. UPDATES AND CORRECTIONS: No other affected persons are identified for the remaining proposed changes.
Compliance costs for affected persons:
No estimable additional compliance costs are expected for affected persons.
Comments by the department head on the fiscal impact the rule may have on businesses:
For most of these proposed revisions, the fiscal impacts are revenue neutral or will result in modest cost savings for businesses. The proposed nutrient criteria have the potential to increase indirect costs for a small percentage of permittees on state or federal lands, although the amount cannot be estimated at this time. The Department is aware of these potential cost increases and is committed to working with interested parties to develop implementation approaches that minimize increases in indirect costs to the greatest extent possible.

Appendix 2: Regulatory Impact to Non - Small Businesses
The impact of these proposed changes are neutral or will result in inestimable indirect costs for non-small businesses. LABORATORY AND FIELD ANALYSES: Non-small businesses are not constrained parties for the proposed revision to Section R317-2-10 because non-small businesses are not required to conduct field analyses. For indirect effects to non-small businesses, the proposed revision is cost neutral or will have inestimable benefits. The proposed revision provides optional flexibility. Presumably, non-small businesses will only exercise these options if they are cost neutral or a benefit. No data is available to estimate the frequency or specifics of these potential requests. SHEEP CREEK USE CHANGE: The impacts are neutral for the addition of the Class 1C use to Sheep Creek in Section R317-2-13 because no non-small businesses are constrained or affected. SILVER CREEK TDS CRITERIA: The proposed revisions to Table 2.14.6 are neutral because no non-small businesses have effluent limits for TDS discharges to Silver Creek. Non-small businesses discharging to publically-owned treatment works may be affected indirectly if they discharge high levels of TDS. These indirect costs are inestimable because no non-small businesses discharging to the Silver Creek Water Reclamation Facility currently have pretreatment limits for TDS. JORDAN RIVER AMMONIA CRITERIA: No non-small businesses are constrained by the proposed Jordan River ammonia criteria in Section R317-2-14 and direct effects are neutral because no non-small businesses have ammonia effluent limits for the affected waters. Non-small businesses discharging to Central Valley Water Reclamation Facility may be affected indirectly if they discharge high levels of ammonia. These indirect costs are inestimable because no non-small businesses currently discharging to CVWRF have pretreatment limits for ammonia. NUTRIENT CRITERIA: State and Federal land management agencies are not constrained parties for the proposed nutrient criteria in Section R317-2-14, nor are other non-small businesses. Non-small businesses could be impacted by indirect costs due to actions by federal or state land management agencies. These agencies grant leases and permits (hereafter in this section, permits refers to both) for non-small businesses to conduct activities such as recreation, oil and gas exploration and production, mining, timber harvesting and grazing on state or federal lands. The land management agencies may elect to modify their leasing or permitting programs to implement best management practices (BMPs) if the activity is determined to cause or contribute to a nutrient impairment. These modifications may result in neutral impacts or increased indirect costs to the permittees. However, these impacts are unlikely to be significant because the affected permitted activities would have to occur in an area co-located with an impaired stream and have been demonstrated to be contributing to the impairment as a source of nitrogen or phosphorus to the stream. Further, implementation measures to address nonpoint sources of pollution are voluntary and are often offset by state and federal nonpoint source grants. New impairments resulting from the proposed nutrient criteria are not anticipated over the next three years, because the Division of Water Quality has a biannual reporting cycle for making impairment determinations, with the first report relevant to these criteria planned for 2022. Plans to restore impairments cannot be developed or implemented until impaired waters are identified. As a result, immediate costs associated with new impairments are anticipated to be neutral, exceptions being inestimable. Once impairment decisions are ultimately made, additional indirect costs to non-small business permittees are inestimable, but likely to be relatively small in size and scope. Based on currently available data, approximately 10-15% of the affected streams may ultimately be classified as impaired (water quality not meeting the proposed nutrient criteria), but these estimates are statistical and additional indirect expense increases, if any, are expected to vary considerably on a case-by-case basis. Even for potentially affected non-small business permittees that are co-located on an impaired stream, increased indirect costs are not inevitable. Impairment determinations trigger additional investigations that are conducted by the Utah Division of Water Quality or other interested parties. Only after the additional investigations, is a final determination made regarding impairment and sources of nutrient pollution. For those non-small businesses ultimately found to be contributing to a nutrient-related impairment as a source of nitrogen and phosphorus, costs are inestimable because there are generally many ways that their contribution to the impairment can be resolved, some of which may be revenue neutral. Costs for other remediation options are often offset through state and federal grants. Interested parties will generally evaluate all possible solutions when crafting restoration plans, and will attempt to select the most cost-effective solutions that are likely to lead to desired water quality improvements. Given the relatively small number of anticipated impairments and the voluntary nature of implementation measures, the proposed nutrient criteria are most likely to be revenue neutral. UPDATES AND CORRECTIONS: There are no costs associated with the remaining updates and corrections to Section R317-2-14.

(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.

(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 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:

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-7.6888))) * 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:

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.
