PART 232
TOXIC AIR CONTAMINANTS
SECTION 232.310 PROCEDURES FOR DETERMINING THE TOXICITY SCORE
Section 232.310 Procedures
for Determining the Toxicity Score
The Toxicity Score is the sum of
the Acute Lethality Score and the Chronic Toxicity Score. The Acute Lethality
Score is a number which indicates a contaminant's potential to cause death.
The Chronic Toxicity Score is a number which indicates a contaminant's
potential to cause adverse health effects after chronic exposure.
a) Procedure for Determining the Acute Lethality Score
1) The Acute Lethality Score is derived from toxicological
studies using laboratory rats. One of two routes of exposure is used:
inhalation or ingestion. Values derived from inhalation are used in preference
to values derived from ingestion.
2) The Acute Lethality Score is derived from the following table:
|
Inhalation Concentration
(LC50)
|
Acute
Lethality Score
|
|
|
|
|
Less than: 500 mg/cu. m

|
b) Procedure for Determining the Chronic Toxicity Score
The Chronic
Toxicity Score is the product of the Lowest Toxic Dose Score and the Severity
of Effects Score.
1) Procedure for Determining the Lowest Toxic Dose Score
The Lowest
Toxic Dose Score is a number based upon the lowest dose of a contaminant that
causes an observable adverse health effect. The Lowest Toxic Dose Score is
derived from the following table:
|
Dose
|
Lowest
Toxic Dose Score
|
|
|
|
Less than: 5 mg/kg
|

|
|
5-50 mg/kg/day
|
⅔
|
|
Greater than: 50 mg/kg/day
|
⅓
|
|
|
|
2) Procedure for Determining the Severity of Effects Score
The Severity
of Effects Score is a number based upon the category of organ(s) affected and
the level of effect upon the organ(s).
A) Organ Categories
There are
three categories of organs or organ systems which are identified as follows:
i) Category I includes: organs, the impairment or loss of which
is fatal or usually cannot be compensated for by the body; gonads, the loss of
which prevents the transmission of genetic material; and, adverse reproductive
outcome including stillbirth, miscarriage, or reduced litter size (animal
studies). The Category I organs are: Lungs, Heart, Brain, Spinal Cord,
Kidneys, Liver, Bone Marrow, and Gonads.
ii) Category II includes: organs, the impairment or loss of
which may be fatal, but which can be compensated for by drug or replacement
therapy; adverse effect on an immune function which may be life threatening;
changes in the composition or function of blood constituents which may be life
threatening; and, certain fetotoxic effects including premature birth, reduced
birth weight, and reduced morphometric parameters. The Category II organs
are: Adrenals, Thyroids, Parathyroids, Pituitary, Pancreas, Esophagus,
Stomach, Small Intestine, Large Intestine, Lymph Nodes, Thymus, Trachea.
iii) Category III includes: organs, the impairment or loss of
which is not life threatening but may result in functional or emotional
handicaps; adverse effect on an immune function which is not life threatening;
changes in composition or function of blood which are not life threatening but
may result in functional handicaps. Category III organs include, but are not
limited to: Oviducts, Epididymides, Uterus, Prostrate, Seminal Vesicles,
Ductus Deferens, Penis, Vagina, Eyes, Bone, Nose, Peripheral Nerves, Muscles,
Urinary Bladder, Blood Vessels, Ears, Gallbladder, Larynx, Mammary Glands,
Salivary Glands, Skin, Spleen, Tongue, Teeth, Ureter, Urethra, Pharynx.
B) Levels of Effect
There are four
levels of effect: Serious Irreversible ("SI"); Serious Reversible
("SR"); Non-serious Irreversible ("NI"); and Non-serious
Reversible ("NR").
i) A serious effect is an incapacitating condition or a
condition which significantly contributes to an increase in mortality.
ii) A non-serious effect is a non-incapacitating condition or a
condition which is unlikely to contribute to an increase in mortality.
iii) An irreversible effect is one that is permanent or would
require medical treatment to correct.
iv) A reversible effect is a temporary effect.
C)
Table of Severity of Effects Scores
The Severity
of Effects Score for any level of effect observed in an organ belonging to a
specified organ category is derived from the following table:
|
|
|
Organ
Category
|
|
|
|
I
|
II
|
III
|
|

|
No Observed Effect
|
|
0
|
0
|
0
|
D) When a study identifies an adverse health effect on multiple
organs within the same category at the lowest observed adverse effect level,
the Severity of Effects Score is increased by a value of 1. In no event can
the Severity of Effects Score be greater than 6.
3) Additional procedures for calculating the Chronic Toxicity
Score are described in Section 232.Appendix B.

for Listing and Delisting Toxic Air Contaminants
a) Any person may submit a regulatory proposal to the Board to
list or delist a toxic air contaminant.
b) The proposal to list a contaminant as a toxic air contaminant,
or to delist a toxic air contaminant, must include, at a minimum, the
following:
1) The contaminant or toxic air contaminant name and Chemical
Abstract Service Number where applicable;
2) The basis for listing or delisting pursuant to Section
232.200(b) or (c). This shall include but is not limited to, a showing of one
of the following:
A) The toxicity score or carcinogen classification is correctly
determined pursuant to the Subpart C procedures;
B) The Subpart C procedure for determining a toxicity score or
carcinogen classification is not appropriate for the contaminant;
C) The Subpart C procedure for determining a toxicity score or
carcinogen classification is incorrectly applied for the contaminant;
D) The studies used are inadequate for the purposes of the Subpart
C procedure; or
E) Additional or new studies should be considered in a
determination to list or delist a contaminant.
3) A copy of each study or report used to justify the proposal.
c) The Agency shall participate in each proposal to list or
delist a toxic air contaminant and must provide the Board with a recommendation
as to advisability of listing or delisting. Such recommendation must include a
toxicity scoring pursuant to Section 232.300 and a carcinogen classification
pursuant to Section 232.310.
d) The Agency will propose an update of the list of toxic air
contaminants to the Board no less frequently than once every 2 years.

PART 232
TOXIC AIR CONTAMINANTS
SECTION 232.APPENDIX B ADDITIONAL PROCEDURES FOR CALCULATING THE CHRONIC TOXICITY SCORE
Section 232.APPENDIX B Additional
Procedures for Calculating the Chronic Toxicity Score
a) Procedures to be used in selecting chronic toxicity studies.
1) Chronic toxicity studies in which all of the items in
subsection (a)(1)(A) of this appendix are identified or measured with adequate
specificity to use the equations in subsection (b) of this appendix are to be
given first preference.
A) Study items to be identified or measured:
i) Test species;
ii) Contaminant dose;
iii) Duration of exposure must be at least 21 days, except for
developmental studies in animals, in which case the duration of exposure must
be during critical gestation days;
iv) Route of exposure; and
v) Effect of exposure.
B) In the event that two or more studies are available in which
the items in subsection (a)(1)(A) are deemed to have been identified or
measured, but which give inconsistent results, the study must be selected by
the following procedures:
i) In the event that two or more studies are laboratory animal
toxicity studies, the study that is conducted in accordance with or consistent
with Good Laboratory Practice Standards must be used. Good Laboratory Practice
Standards are incorporated by reference in Section 232.110.
ii) In the event that the application of the procedure in
subsection (i) fails to result in the selection of one study, then the study
that results in the highest Chronic Toxicity Score must be used.
2) Studies that identify or measure all of the items in
subsection (a)(1)(A) of this appendix, except for the contaminant dose, must be
given second preference.
A) For a second preference study, the Lowest Toxic Dose Score for
a given species and a given route of exposure must be determined according to
the following table:
|

|

Toxic Dose Score
|

|
⅔
|
|

|
⅔
|
|
Non-human
|

|
⅓
|
B) In the event that two or more second preference studies are
available, the study that results in the highest Chronic Toxicity Score must be
used.
3) A contaminant for which there is insufficient data in the
study to identify the elements of either a first or second preference study
must be determined to have no data and be assigned a Chronic Toxicity Score of
0.
b) The following general equation must be used to obtain the dose
in units of milligram per kilogram per day for the oral, gavage and inhalation
routes of exposure: Dose = (I)(C)(TCF)/UF
1) For the routes of exposure listed below, use the following:
|
TCF
|
=
|
Time Correction Factor of 1,
unless the exposure was intermittent, in which case the fraction of time
during which exposure occurred is used (e.g., 5 days/week = 5/7
= 0.71).
|
|
|
|
|
|
UF
|
=
|
Uncertainty Factor of 10, used
only when data are for exposure periods less than 90 days. In the case of
fetotoxicity and teratogenicity studies, an Uncertainty Factor of 1 must be
used.
|
|
|
|
|
2) Where the exposure is oral use the following:
A) Oral Exposure via Food:
|
I
|
=
|
Food Intake in kilogram of
food ingested per kilogram of body weight per day (kg/kg-d) (refer to Chart 1
for standard values);
|
|
|
|
|
|
C
|
=
|
Contaminant Concentration in
food in units of milligram per kilogram (mg/kg); or
|
B) Oral Exposure via Water:
|
I
|
=
|
Water Intake in liter of water
ingested per kilogram of body weight per day (L/kg-d) (refer to Chart 1 for
standard values);
|
|
|
|
|
|
C
|
=
|
Contaminant Concentration in
water in units of milligram per liter (mg/L);
|
3) Where the exposure is via gavage use the following:
The product (I
X C) in the above equation must be replaced by Gavage Dose (GD) in units of
milligram of contaminant ingested per kilogram of body weight per day
(mg/kg-d); or
4) Where the exposure is via inhalation use the following:
|
I
|
=
|
Air intake in cubic meter of
air inhaled per kilogram of body weight per day (cu.m3/kg-d) measured as the
product of Ventilation Rate (VR) (refer to Chart 1 for standard values) and
Inhalation retention factor (RF) (assumed to be 0.5 for this procedure);
|
|
|
|
|
|
C
|
=
|
Contaminant Concentration in
air in units of milligram per cubic meter (mg/cu.m).
