(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These indicators are superseded by numeric criteria in waters where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.

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 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.
