Section 302.208 Numeric Standards for Chemical Constituents

 

a) The acute standard (AS) for the chemical constituents listed in subsection

(e) shall not be exceeded at any time except as provided in subsection (d).

 

b) The chronic standard (CS) for the chemical constituents listed in

subsection (e) shall not be exceeded by the arithmetic average of at least

four consecutive samples collected over any period of at least four days,

except as provided in subsection (d). The samples used to demonstrate

compliance or lack of compliance with a CS must be collected in a manner

which assures an average representative of the sampling period.

 

c) The human health standard (HHS) for the chemical constituents listed in

subsection (f) shall not be exceeded when the stream flow is at or above

the harmonic mean flow pursuant to Section 302.658 nor shall an annual

average, based on at least eight samples, collected in a manner

representative of the sampling period, exceed the HHS except as provided

in subsection (d).

 

d) In waters where mixing is allowed pursuant to Section 302.102, the

following apply:

 

1) The AS shall not be exceeded in any waters except for those

waters for which the Agency has approved a ZID pursuant to

Section 302.102.

Section 302.575 Procedures for Deriving Tier I Water Quality Criteria and

Values in the Lake Michigan Basin to Protect Wildlife

 

The Lake Michigan Basin Wildlife Criterion (LMWC) is the concentration of a substance

which if not exceeded protects Illinois wild mammal and bird populations from adverse

effects resulting from ingestion of surface waters of the Lake Michigan Basin and from

ingestion of 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 utilization 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.

 

d) Calculation of TSV. The TSV, measured in milligrams per liter (mg/L), is

calculated according to the equation:

 

TSV = { [TD x Wt] / [UFa x UFs x UFl] } / { W +

Σ

[FTLi x BAFWLTLi] }

 

Where:

 

TSV = target species value in milligrams of substance per liter (mg/L).

TD = test dose that is toxic to the test species, either NOAEL or LOAEL.

POLLUTION CONTROL BOARD

 

NOTICE OF PROPOSED AMENDMENTS

 

UFa = the uncertainty factor for extrapolating toxicity data across species

(unitless). A species-specific UFa shall be selected and applied to each

target species, consistent with the equation

UFs = the uncertainty factor for extrapolating from subchronic to chronic

exposures (unitless)

UFl = the uncertainty factor for extrapolation from LOAEL to NOAEL

(unitless)

Wt = average weight in kilograms (kg) of the target species

W = average daily volume of water in liters consumed per day (L/d) by

the target species

FTLi = average daily amount of food consumed by the target species in

kilograms (kg/d) for trophic level i

BAFWLTLi = aquatic life bioaccumulation factor with units of liter per

kilogram (L/kg), as derived in Section 302.570 for trophic level

 

e) Calculation of the Lake Michigan Basin Wildlife Criterion. TSVs are

obtained for each target species. The geometric mean TSVs of all

mammal species is calculated and also of all bird species. The LMWC is

the lower of the bird or mammal geometric mean TSV.
