Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 302 - WATER QUALITY STANDARDS › Subpart E - LAKE MICHIGAN BASIN WATER QUALITY STANDARDS › Section 302.555 - Determining the Tier I Lake Michigan Acute Aquatic Toxicity Criterion (LMAATC): Independent of Water Chemistry

Current through Register Vol. 48, No. 28, July 12, 2024
If the acute toxicity of the chemical has not been shown to
				  be related to a water quality characteristic, including hardness, pH, or
				  temperature, the Tier I LMAATC is calculated using the procedures below.
a) For each species for which more than one
				acute value is available, the Species Mean Acute Value (SMAV) is calculated as
				the geometric mean of the acute values from all tests.
b) For each genus for which one or more SMAVs
				are available, the Genus Mean Acute Value (GMAV) is calculated as the geometric
				mean of the SMAVs available for the genus.
c) The GMAVs are ordered from high to low in
				numerical order.
d) Ranks (R) are
				assigned to the GMAVs from "1" for the lowest to "N" for the highest. If two or
				more GMAVs are identical, successive ranks are arbitrarily assigned.
e) The cumulative probability, P, is
				calculated for each GMAV as R/(N+1).
f) The GMAVs to be used in the calculations
				of subsection (g) must be those with cumulative probabilities closest to
				0.05. If there are fewer than 59
				GMAVs in the total data set, the values utilized must be the lowest four
				obtained through the ranking procedures of subsections (c) and (d).
g) Using the GMAVs identified under
				subsection (f) and the Ps calculated under subsection (e), the Final Acute
				Value (FAV) and the LMAATC are calculated as:
FAV = exp(A) and
LMAATC = FAV/2
Where:
A
=
L +
							 0.2236 S
L
=
[[SIGMA](lnGMAV) - S([SIGMA](P(0.5) ))]/4
S
=
[[[SIGMA]((lnGMAV)2) -
							 (([SIGMA](lnGMAV))2)/4] / [[SIGMA](P) -
							 (([SIGMA](P0.5))2)/4]]0.5
h) If
				a resident or indigenous species whose presence is necessary to sustain
				commercial or recreational activities will not be protected by the calculated
				FAV, then the SMAV for that species is used as the FAV.
Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 302 - WATER QUALITY STANDARDS › Subpart E - LAKE MICHIGAN BASIN WATER QUALITY STANDARDS › Section 302.563 - Determining the Tier II Lake Michigan Basin Acute Aquatic Life Toxicity Value (LMAATV)

Current through Register Vol. 48, No. 28, July 12, 2024
If all eight minimum data requirements for calculating a FAV
				  using Tier I procedures are not met, a Tier II LMAATV must be calculated for a
				  substance as follows:
a) The lowest
				GMAV in the database is divided by the Secondary Acute Factor (SAF)
				corresponding to the number of satisfied minimum data requirements listed in
				the Tier I methodology (Section
				302.553). To calculate a Tier II
				LMAATV, the database must contain, at a minimum, a GMAV for one of the
				following three genera in the family Daphnidae -
Ceriodaphnia
sp.,
Daphnia
sp., or
Simocephalus
sp. The
				Secondary Acute Factors are:
Number of Minimum data requirements
							 satisfied (required taxa)
Secondary Acute Factor

43.8
2
26.0
3
16.0
4
14.0
5
12.2
6
10.4
7
8.6
b) If
				dependent on a water quality characteristic, the Tier II LMAATV must be
				calculated according to Section
				302.560.
Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 302 - WATER QUALITY STANDARDS › Subpart E - LAKE MICHIGAN BASIN WATER QUALITY STANDARDS › Section 302.565 - Determining the Lake Michigan Basin Chronic Aquatic Life Toxicity Criterion (LMCATC) or the Lake Michigan Basin Chronic Aquatic Life Toxicity Value (LMCATV)

Current through Register Vol. 48, No. 28, July 12, 2024
a)
				Determining Tier I LMCATC
1) When chronic
				toxicity data are available for at least eight resident or indigenous species
				from eight different North American genera of freshwater organisms as specified
				in Section 302.553, a Tier I LMCATC is
				derived in the same manner as the FAV in Section
				302.555 or
				302.560 by substituting LMCATC
				for FAV or FAI, chronic for acute, SMCV (Species Mean Chronic Value) for SMAV,
				and GMCV (Genus Mean Chronic Value) for GMAV.
2) If data are not available to meet the
				requirements of subsection (a), a Tier I LMCATC is calculated by dividing the
				FAV by the geometric mean of the acute-chronic ratios (ACRs) obtained from at
				least one species of aquatic animal from at least three different families
				provided that of the three species:
A) At
				least one is a fish;
B) At least
				one is an invertebrate; and
C) At
				least one species is an acutely sensitive freshwater species if the other two
				are saltwater species.
3)
				The acute-chronic ratio (ACR) for a species equals the acute toxicity
				concentration from data considered under Section
				302.555 or 302.560, divided by
				the chronic toxicity concentration.
4) If a resident or indigenous species whose
				presence is necessary to sustain commercial or recreational activities will not
				be protected by the calculated LMCATC, then the SMCV for that species is used
				as the CATC.

Current through Register Vol. 48, No. 28, July 12, 2024
A bioaccumulation factor (BAF) is used to relate the
				  concentration of a substance in an aquatic organism to the concentration of the
				  substance in the waters in which the organism resides when all routes of
				  exposure (ambient water and food) are included. A BAF is used in the derivation
				  of water quality criteria to protect wildlife and criteria and values to
				  protect human health.
a) Selection of
				Data. BAFs can be obtained or developed from one of the following methods,
				listed in order of preference.
1)
				Field-measured BAF.
2)
				Field-measured biota-sediment accumulation factor (BSAF).
3) Laboratory-measured bioconcentration
				factor (BCF).
The concentration of particulate organic carbon (POC) and
				  dissolved organic carbon (DOC) in the test solution must be either measured or
				  reliably estimated.
4)
				Predicted BCF.
Predicted baseline BCF = Kow.

Current through Register Vol. 48, No. 28, July 12, 2024
The Lake Michigan Basin Wildlife Criterion (LMWC) is the
				  concentration of a substance that, if not exceeded, protects Illinois wild
				  mammal and bird populations from adverse effects resulting from the ingestion
				  of surface waters of the Lake Michigan Basin or aquatic prey organisms taken
				  from surface waters of the Lake Michigan Basin. Wildlife criteria calculated
				  under this Section protect against long-term effects and are therefore
				  considered chronic criteria. The methodology involves the use of data from test
				  animals to derive criteria to protect representative or target species: bald
				  eagle, herring gull, belted kingfisher, mink, and river otter. The lower of the
				  geometric mean of species-specific criteria for bird species or mammal species
				  is chosen as the LMWC to protect a broad range of species.
a) This method must also be used for non-BCCs
				when appropriately modified to consider the following factors:
1) Selection of scientifically justified
				target species;
2) Relevant routes
				of chemical exposure;
3) Pertinent
				toxicity endpoints.
Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 302 - WATER QUALITY STANDARDS › Subpart E - LAKE MICHIGAN BASIN WATER QUALITY STANDARDS › Section 302.580 - Procedures for Deriving Water Quality Criteria and Values in the Lake Michigan Basin to Protect Human Health - General

Current through Register Vol. 48, No. 28, July 12, 2024
a) The Lake Michigan Basin human health
				criteria or values for a substance are those concentrations at which humans are
				protected from adverse effects resulting from incidental exposure to, or
				ingestion of, the waters of Lake Michigan and from ingestion of aquatic
				organisms taken from the waters of Lake Michigan. A Lake Michigan Human Health
				Threshold Criterion (LMHHTC) or Lake Michigan Human Health Threshold Value
				(LMHHTV) will be calculated for all substances according to Section
				302.585, if data is available.
				Water quality criteria or values for substances that are, or may be,
				carcinogenic to humans will also be calculated according to procedures for the
				Lake Michigan Human Health Nonthreshold Criterion (LMHHNC) or the Lake Michigan
				Human Health Nonthreshold Value (LMHHNV) in Section
				302.590.
b) Minimum data requirements for BAFs for
				Lake Michigan Basin human health criteria:
1)
				Tier I
A) For all organic chemicals, either a
				field-measured BAF or a BAF derived using the BSAF methodology is required
				unless the chemical has a BAF less than 125, then a BAF derived by any
				methodology is required; and
B) For
				all inorganic chemicals, including organometals such as mercury, either a
				field-measured BAF or a laboratory-measured BCF is required.
Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 302 - WATER QUALITY STANDARDS › Subpart E - LAKE MICHIGAN BASIN WATER QUALITY STANDARDS › Section 302.585 - Procedures for Determining the Lake Michigan Basin Human Health Threshold Criterion (LMHHTC) and the Lake Michigan Basin Human Health Threshold Value (LMHHTV)

Current through Register Vol. 48, No. 28, July 12, 2024
The LMHHTC or LMHHTV is derived for all toxic substances from
				  the most sensitive endpoint for which there exists a dosage or concentration
				  below which no adverse effect or response is likely to occur.
a) Minimum Data Requirements
1) Tier I. The minimum data set sufficient to
				derive a Tier I LMHHTC must include at least one epidemiological study or one
				animal study of greater than 90 days duration; or
2) Tier II. When the minimum data for
				deriving Tier I criteria are not available, a more limited database consisting
				of an animal study of greater than 28 days duration must be used.

Current through Register Vol. 48, No. 28, July 12, 2024
An LMHHNC or LMHHNV must be derived for those toxic
				  substances for which any exposure, regardless of extent, carries some risk of
				  damage from cancer or a nonthreshold toxic mechanism. For single or
				  combinations of substances, a risk level of 1 in 100,000 (or
				  10-5) must be used to determine an LMHHNC or
				  LMHHNV.
a) Minimum Data Requirements.
				Minimal experimental or epidemiological data requirements are incorporated in
				the cancer classification determined by USEPA in Appendix C II A to
				40 CFR
				132, incorporated by reference at 35 Ill.
				Adm. Code 301.106.
b) Principles for Development of Criteria or
				Values
1) Animal data are fitted to a
				linearized multistage computer model (Global 1986 in "Mutagenicity and
				Carcinogenicity Assessment for 1, 3-Butadiene" September 1985
				EPA/600/8-85/004A, incorporated by reference at 35 Ill. Adm. Code
				301.106 or scientifically
				justified equivalents). The upper-bound 95 percent confidence limit on risk at
				the 1 in 100,000 risk level must be used to calculate a risk associated dose
				(RAD); and
2) A species scaling
				factor must be used to account for differences between test species and humans.
				Milligrams per surface area per day is an equivalent dose between species. All
				doses presented in mg/kg body weight will be converted to an equivalent surface
				area dose by raising the mg/kg dose to the 3/4 power.

As used in this Subpart, the following terms have the
				  meanings specified.
"Bioconcentration" means an increase in the concentration of
				  a chemical and its metabolites in an organism (or its specified tissues)
				  relative to the concentration of the chemical in the ambient water acquired
				  through contact with the water alone.
"Carcinogen" means a chemical that causes an increased
				  incidence of benign or malignant neoplasms, or a statistically significant
				  decrease in the latency period between exposure and onset of neoplasms, in at
				  least one mammalian species or man through epidemiological or clinical
				  studies.
"EC-50" means the concentration of a substance or effluent
				  that causes a given effect to 50% of the exposed organisms in a given time
				  period.
"LC-50" means the concentration of a toxic substance or
				  effluent that is lethal to 50% of the exposed organisms in a given time
				  period.
"LOAEL" or "Lowest Observable Adverse Effect Level" means the
				  lowest tested concentration of a chemical or substance that produces a
				  statistically significant increase in frequency or severity of non-overt
				  adverse effects between the exposed population and its appropriate
				  control.
"MATC" or "Maximum Acceptable Toxicant Concentration" means
				  the value obtained by calculating the geometric mean of the lower and upper
				  chronic limits from a chronic test. A lower chronic limit is the highest tested
				  concentration that did not cause a specified adverse effect. An upper chronic
				  limit is the lowest tested concentration that did cause a specified adverse
				  effect and above which all tested concentrations caused a specified adverse
				  effect.
"NOAEL" or "No Observable Adverse Effect Level" means the

				  a statistically significant increase in frequency or severity of non-overt
				  adverse effects between the exposed population and its appropriate
				  control.
"Resident or Indigenous Species" means species that currently
				  live a substantial portion of their lifecycle or reproduce in a given body of
				  water or that are native species whose historical range includes a given body
				  of water.

Current through Register Vol. 48, No. 28, July 12, 2024
If the acute toxicity of the chemical has not been shown to
				  be related to a water quality characteristic, including hardness, pH, or
				  temperature, the AATC is calculated by using the procedures below.
a) For each species for which more than one
				acute value is available, the Species Mean Acute Value (SMAV) is calculated as
				the geometric mean of the acute values from all tests.
b) For each genus for which one or more SMAVs
				are available, the Genus Mean Acute Value (GMAV) is calculated as the geometric
				mean of the SMAVs available for the genus.
c) The GMAVs are ordered from high to
				low.
d) Ranks (R) are assigned to
				the GMAVs from "1" for the lowest to "N" for the highest. If two or more GMAVs
				are identical, successive ranks are arbitrarily assigned.
e) The cumulative probability, P, is
				calculated for each GMAV as R/(N + 1).
f) The GMAVs to be used in the calculations
				of subsection (g) must be those with cumulative probabilities closest to
				0.05. If there are less than 59
				GMAVs in the total data set, the values utilized must be the lowest obtained

				taxa listed below. T is equal to 2 when the data set meets the minimum
				requirements of Section
				302.612 but does not include
				representatives from any of the three taxa listed below. When toxicity data on
				any of the three taxa listed below are available, they must be used along with
				the minimum data required pursuant to Section 302.612.

Current through Register Vol. 48, No. 28, July 12, 2024
The Wild and Domestic Animal Protection Criterion (WDAPC) is
				  the concentration of a substance that, if not exceeded, protects Illinois wild
				  and domestic animals from adverse effects, such as functional impairment or
				  pathological lesions, resulting from ingestion of surface waters of the State
				  or ingestion of aquatic organisms taken from surface waters of the
				  State.
a) For those substances for
				which a NOAEL has been derived from studies of mammalian or avian species
				exposed to the substance via oral routes including gavage, the lowest NOAEL
				among species must be used in calculating the WDAPC. Additional considerations
				in selecting NOAEL include:
1) If the NOAEL is
				given in milligrams of toxicant per liter of water consumed (mg/L), before
				calculating the WDAPC, the NOAEL must be multiplied by the daily average volume
				of water consumed by the test animals in liters per day (L/d) and divided by
				the average weight of the test animals in kilograms (kg).
2) If the NOAEL is given in milligrams of
				toxicant per kilogram of food consumed (mg/kg), before calculating the WDAPC,
				the NOAEL must be multiplied by the average amount of food in kilograms
				consumed daily by the test animals (kg/d) and divided by the average weight of
				the test animals in kilograms (kg).
3) If the animals used in a study were not
				exposed to the toxicant each day of the test period, the NOAEL must be
				multiplied by the ratio of days of exposure to the total days in the test
				period.
4) If more than one NOAEL
				is available for the same animal species, the geometric mean of the NOAELs must
				be used to calculate the WDAPC.

				given in milligrams per liter (mg/L) by 2 liters per day (L/d).
2) For substances listed with a maximum
				allowable concentration standard in 35 Ill. Adm. Code Subtitle F, the
				acceptable daily intake equals the product of multiplying the public health
				enforcement standard given in milligrams per liter (mg/L) by 2 liters per day
				(L/d).

Current through Register Vol. 48, No. 28, July 12, 2024
The Human Nonthreshold Criterion (HNC) of a substance is the
				  concentration or level of a substance at which humans are protected from an
				  unreasonable risk of disease caused by a nonthreshold toxic mechanism as a
				  result of incidental exposure to or ingestion of surface waters of the State or
				  ingestion of aquatic organisms taken from surface waters of the State. HNCs are
				  derived for those toxic substances for which any exposure, regardless of
				  extent, carries some risk of damage as specified in subsections (a) and
				  (b).
a) For single substances, a risk
				level of one in one million (1 in 1,000,000) must be allowed (i.e., considered
				acceptable) to determine an HNC.

Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 302 - WATER QUALITY STANDARDS › Subpart F - PROCEDURES FOR DETERMINING WATER QUALITY CRITERIA › Section 302.657 - Determining the Human Nonthreshold Criterion

Current through Register Vol. 48, No. 28, July 12, 2024
The HNC is calculated according to the equation:
HNC = RAI/[W + (F x BCF)]
where:
HNC
=
Human Nonthreshold Protection Criterion in milligrams
							 per liter (mg/L);
RAI
=
Risk Associated Intake of a substance in milligrams
							 per day (mg/d) that is associated with a lifetime cancer risk level equal to a
							 ratio of one to 1,000,000 as derived in Section
							 302.654;
W
=
Per capita daily water consumption equal to 2 liters
							 per day (L/d) for surface waters at the point of intake of a public or food
							 processing water supply, or equal to
							 0.01 liters per day (L/d) which
							 represents incidental exposure through contact or ingestion of small volumes of
							 water while swimming or during other recreational activities for areas which
							 are determined to be public access areas under Section
							 302.102(b)(3),
							 or 0.001 liters per day (L/d) for
							 other waters;
F
=
Assumed daily fish consumption in the United States
							 equal to 0.020 kilograms per day (kg/d);
							 and
BCF
=
Aquatic Life Bioconcentration Factor with units of
							 liter per kilogram (L/kg) as derived in Section
							 302.663.
Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 302 - WATER QUALITY STANDARDS › Subpart F - PROCEDURES FOR DETERMINING WATER QUALITY CRITERIA › Section 302.658 - Stream Flow for Application of Human Nonthreshold Criterion

Current through Register Vol. 48, No. 28, July 12, 2024
The HNC applies at all times except during periods when flows
				  are less than the harmonic mean flow (Qhm), as determined by:
Qhm = N / SUM(1/Qi)
Where:
Qhm
=
harmonic mean flow,
N
=
number of daily values for streamflows, and
Qi
=
daily streamflow value on day i.
Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 302 - WATER QUALITY STANDARDS › Subpart F - PROCEDURES FOR DETERMINING WATER QUALITY CRITERIA › Section 302.660 - Bioconcentration Factor

Current through Register Vol. 48, No. 28, July 12, 2024
A Bioconcentration Factor is used to relate substance residue
				  in aquatic organisms to the concentration of the substance in the waters in
				  which the organisms reside.
Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 302 - WATER QUALITY STANDARDS › Subpart F - PROCEDURES FOR DETERMINING WATER QUALITY CRITERIA › Section 302.663 - Determination of Bioconcentration Factors

Current through Register Vol. 48, No. 28, July 12, 2024
A Bioconcentration Factor equals the concentration of a
				  substance in all or part of an aquatic organism in milligrams per kilogram of
				  wet tissue weight (mg/kg), divided by the concentration of the substance in the
				  water to which the organism is exposed in milligrams of the substance per liter
				  of water (mg/L).
a) The
				Bioconcentration Factor is calculated from a field study if the following
				conditions are met:
1) Data are available to
				show that the concentration of the substance in the water to which the organism
				was exposed remained constant over the range of territory inhabited by the
				organism and for a period of time exceeding 28 days;
2) Competing mechanisms for removal of the
				substance from solution did not affect the bioavailability of the substance;
				and
3) The concentration of the
				substance to which the organism was exposed is less than the lowest
				concentration causing any adverse effects on the organism.
Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 302 - WATER QUALITY STANDARDS › Subpart F - PROCEDURES FOR DETERMINING WATER QUALITY CRITERIA › Section 302.666 - Utilizing the Bioconcentration Factor

Current through Register Vol. 48, No. 28, July 12, 2024
The Bioconcentration Factor derived in Section
				  302.663 is used to calculate
				  water quality criteria for a substance as specified below:
a) When calculating a WDAPC as described in
				Section 302.633, the geometric mean of
				all available steady-state, whole-body Bioconcentration Factors for fish and
				shellfish species that constitute or represent a portion of the diet of
				indigenous wild and domestic animal species is used. Additional considerations
				in deriving a Bioconcentration Factor include:
1) An edible portion Bioconcentration Factor
				is converted to a whole-body Bioconcentration Factor for a fish or shellfish
				species by multiplying the edible portion Bioconcentration Factor by the ratio
				of the percent lipid in the whole body to the percent lipid in the edible
				portion of the same species.
2) A
				Bioconcentration Factor calculated as described in Section
				302.663(c) is
				converted to a whole-body Bioconcentration Factor by multiplying the calculated
				Bioconcentration Factor by the ratio of the percent lipid in the whole body to
				7.6.
Illinois Administrative Code › Title 35 - ENVIRONMENTAL PROTECTION › Part 302 - WATER QUALITY STANDARDS › Subpart F - PROCEDURES FOR DETERMINING WATER QUALITY CRITERIA › Section 302.669 - Listing of Derived Criteria

Current through Register Vol. 48, No. 28, July 12, 2024
a) The
				Agency must develop and maintain a listing of toxicity criteria pursuant to
				this Subpart. This list must be made available to the public and updated
				whenever a new criterion is derived and must be published when updated in the
				Illinois Register.
b) A criterion
				published pursuant to subsection (a) may be proposed to the Board for adoption
				as a numeric water quality standard.
c) The Agency must maintain for inspection
				all information, including assumptions, toxicity data, and calculations, used
				to derive any toxicity criterion listed pursuant to subsection (a) until
				adopted by the Board as a water quality standard.
