I. INTRODUCTION
The List Work Group, a component of EPA's Air Toxics Strategy, asked ICF
Incorporated to identify lists of hazardous chemicals developed by other
organizations. ICF identified many lists, ten of which are discussed here.
ICF examined the purpose of each list, the general criteria used to create
each list (consistent with the purpose), and the actual chemicals and classes
of chemicals on each list.
This report, presents the criteria used by each of the groups to develop
its list. The ten lists discussed in this report are: European Communities
(EC) Council Directive Chemical Hazard List, World Bank Chemical Hazard List,
California's Air Resources Board Toxic Chemical List, New Jersey's Department
of Environmental Protection Highly Toxic Substances List, House of
Representatives Bill H.R. 2576, CERCLA Reportable Quantities, the Department
of Transportation's Poisonous Substances List, Philadelphia Air Pollution
Control Board Toxic Air Contaminants List, Union Carbide Corporation
Industrial Hygiene Sampling and Monitoring Program List, and the Unregulated
Air Toxins List Identified by Congressman Henry Waxman. The impetus to
develop five of these lists (World Bank, California, New Jersey, H.R. 2576,
and the Unregulated Air Toxins) was the recent disaster in Bhopal, India, with
methyl isocyanate. The incident at Seveso, Italy, resulted in the development
of the EC list. The remaining four lists were developed independently of any
major industrial disaster. The purposes of the lists are described briefly,
followed by a more detailed discussion of the specific criteria used to arrive
at each list. A summary exhibit presenting the specific criteria for eight
chemical hazards lists may be found in Appendix A-l and for the remaining two
lists in Appendix A-2. The individual chemicals in each of the ten lists are
presented in Appendix B, along with their respective Chemical Abstracts
Service (CAS) Registry Numbers which were used for computer comparisons of the
lists.
The purposes of the ten lists of hazardous chemicals are summarized in
Exhibit 1. The basic purpose of seven of the lists is to identify specific
chemicals that could pose severe health hazards to the surrounding populations
if accidentally released into the air. The seven lists that have this common
purpose are from the following organizations: EC, World Bank, California Air
Resources Board, New Jersey DEP, House of Representatives Bill H.R. 2576, the
Unregulated Air Toxins, and Union Carbide. The differences among the lists of
chemicals are a consequence of geographic locations of the respective
organizations, industries of concern to the respective organizations, and
areas of jurisdiction of the respective organizations.
The other three lists, CERCLA Reportable Quantities, DOT's Poisonous
Substances, and Philadelphia's Toxic Air Contaminants, have different
purposes. The purpose of CERCLA Reportable Quantities is much more
comprehensive than the previous seven lists. As well as identifying both
acutely and chronically hazardous chemicals, it provides for Federal authority
to deal with releases or threats of releases of these chemicals into any
medium, not just air. The DOT Poisonous Substance List is concerned only with
substances being transported. Its purpose is to identify those substances

that may present risks to health, safety, and property during transport of
such materials. The list is a subsection of a much larger list of products
posing a variety of hazards. The larger list is intended to be used to
classify, label, and package substances for transport. The Philadelphia Toxic
Air Contaminants List is not concerned with accidental releases but rather,
focuses on expected chemical emissions from industrial plants. Its purpose is
to identify chemical air pollutants that may have chronic effects. If a
chemical is not produced or used in the Philadelphia area, it is not included
in the list.
While the purposes of the certain of these lists are similar to that of
the EPA Acutely Toxic Chemicals List, none contain all of the components
deemed necessary by the EPA. Therefore, the EPA has developed its own list.
The criteria for the EPA Acutely Toxic Chemicals List may be found in

II. LIST CRITERIA
A. European Communities Council Directive Chemical Hazard List
The European Communities Council Directive of 24 June 1982 on the
major-accident hazards of certain industrial activities (82/501/EEC, OJ No L
230, 5.8.82, pp. 1-18) is concerned with the prevention of major accidents and
the limitation of their consequences for man and the environment. It includes
provisions for reporting by manufacturers whose activities involve the use of
any of a list of specified chemicals in amounts over a specified quantity.
Industrial installations covered by this Directive include the following,
if they involve dangerous substances (as defined in Section 1):
Producers or processors of organic or inorganic
chemicals;
Distillers, refiners, or other processors of petroleum
or petroleum products;
Installations for the disposal of solids or liquids by
incineration or chemical decomposition;
Producers or processors of energy gases;
Installations for the dry distillation of coal or
lignite; and
Producers of metals or non-metals by the wet process
or by electrical energy.
Manufacturers in these categories must notify the authorities if their
activities involve the use of any substances that appear on a list of 178
dangerous substances, in quantities specified in the list. In addition, all
manufacturers must notify the appropriate authorities if they have stored any
of the substances on an additional list of nine dangerous substances in
specified quantities. Activities and installations not covered by the
Directive are:
Nuclear installations and processors of radioactive
materials;
Military installations;
Manufacture and storage of explosives, gunpowder and
ammunitions;
Extraction and other mining operations; and
Installations for the disposal of toxic and dangerous
waste which are covered by Community Acts for the
prevention of major accidents.
-6-
-------
1. Criteria for Dangerous Substances
The indicative criteria for dangerous substances in this Directive are
discussed below and presented in tabular form in Exhibit 3.
a. Very Toxic Substances
Very toxic substances meet one of the following criteria:
Oral LDrn (mg/kg body weight) of less than or equal
to 5 in rats; or
Cutaneous LDc0 (mg/kg body weight) of less than or
equal to 10 in rats or rabbits; or
Four-hour inhalation LC,.. (mg/1) of less than or
equal to 0.1 in rats.
The following criteria are used to define very toxic substances if, because of
their physical and chemical properties (these properties are not specified),
they are capable of entailing major-accident hazards similar to those caused
by substances meeting one of the above criteria:
Oral LD (mg/kg body weight) of greater than 5 and
less than or equal to 25 in rats; or
Cutaneous LD50 (mg/kg body weight) of greater than
10 and less than or equal to 50 in rats or rabbits; or
Four-hour inhalation LC (mg/1) of greater than 0.1
and less than or equal to 0.5 in rats.
b. Other Toxic Substances
Other toxic substances meet one of the following criteria and have
physical and chemical properties (unspecified) capable of causing major
accident hazards:
Oral LD (mg/kg. body weight) greater than 25 and
less than or equal to 200 in rats; or
Cutaneous LD (mg/kg body weight) greater than 50
and less than or equal to 400 in rats or rabbits; or
Four-hour inhalation LC__ (mg/1) greater than 0.5
and less than or equal to 2 in rats.

-------
c. Flammable Substances
Flammable substances are defined as follows:
1. Flammable gases are substances whose boiling point at
normal pressure is 20°C or below and which become
flammable when mixed with air in the gaseous state at
normal pressure.
2. Highly flammable liquids are substances whose flash
point is lower than 21°C and whose boiling point at
normal pressure is above 20°C.
3. Flammable liquids are defined as substances which have a
flash point below 55°C and remain liquid under pressure
and where particular processing conditions, e.g., high
pressure and high temperature, may create major accident
hazards.
d. Explosive Substances
Explosive substances are those substances that may explode under
the effect of flame or are more sensitive to shocks or friction than
dinitrobenzene.
2. List of Dangerous Substances
The Directive, as mentioned earlier, contains a list of 178 specific
dangerous substances. (This list can be found in Appendix B.) Manufacturers
who produce or use specified quantities of any of these substances must report
data concerning the properties of these substances, how the substances are
used, and precautions taken in handling them. The substances on this list
presumably meet one or more of the criteria for dangerous substances listed
above, but this is not explicitly stated in the Directive. The Directive does
not state whether this list is a complete list of substances meeting the
criteria; however, provisions are included for adapting the list to technical
progress, which implies that it is intended to be fairly inclusive and
up-to-date.
Some listings with low quantities specified do not meet the criteria for
dangerous substances but are known or suspected carcinogens, indicating that
carcinogenicity may have been a criterion. Examples are 4-aminobiphenyl ~and
benzidine. In addition to carcinogenicity, it appears that previous
experience (that is, a substance having presented a health hazard in the past)
may have possibly been used as a criterion, although it is not mentioned.
Other substances which do not meet the criteria, such as ammonia, chlorine,
and sulfur dioxide, have large quantities specified. Apparently these
materials are believed to be dangerous in large quantities, possibly because
of previous experience.
-9-
-------
The list includes the three categories of flammable substances defined in
the section on criteria (flammable gases, highly .flammable liquids, and
flammable liquids). Three substances on the list are elements and their
(unspecified) compounds: beryllium (powders, compounds); cobalt (powders,
compounds); and nickel (powders, compounds). Three entries are for specific
compounds and unspecified salts of those compounds: arsenic pentoxide,
arsenic (V) acid and salts; arsenic trioxide, arsenious (III) acid and salts;
and dinitrophenol and salts. There are separate entries for benzidine and
benzidine salts. Entries for four fluoro-organic acids (4-fluorobutyric acid,
4-fluorocrotonic acid, fluoroacetic acid, and 4-fluoro-2-hydroxybutyric acid)
are followed by separate entries for unspecified salts, esters, and amides of
the acid. For those cases in which specific compounds are not listed, CAS
numbers are not included in the list.
The process by which the list of substances was compiled is not described
in the Directive or in committee reports preceding the Directive. Apparently
one of the sources used was a 1967 Directive on classification, packaging, and
labeling of dangerous substances (67/548/EEC) and its amendments; it is noted
that EEC numbers included in the list are from the earlier Directive.
. 3. List of Dangerous Substances for Storage
In addition to the list of 178 dangerous substances described above, a
shorter list of nine substances is provided in the Directive. Companies
storing over a specified quantity of any of these nine substances are required
to report the pertinent data to the authorities. With one exception, all of
the substances on this list are included on the list of 178 substances
described in the previous section, although the quantities specified are
different in some cases. Therefore, the shorter list will not be analyzed.
The one substance included on the short list but not on the list of 178
substances is liquid oxygen; the reason liquid oxygen is not included in the
list of 178 substances is not stated, but presumably this omission is due to
the specific nature of liquid oxygen.

-------
B. World Bank Chemical Hazard List
The World Bank has developed a set of guidelines for identifying, analy-
zing, and controlling major hazard installations in developing countries.
These guidelines are based substantially on the European Communities' directive
on major-accident hazards of certain industrial activities and regulations
promulgated under the United Kingdom Health and Safety at Work Act. They
apply generally to industrial processes, storage, and transportation of
hazardous materials but do not apply to nuclear operations, extraction or
mining operations, or to licensed hazardous waste disposal sites. The
guidelines seek to provide a framework in which a developer can supply
evidence and justification for the safe operation of a proposed industrial
activity by ensuring that persons in control of activities involving certain
dangerous, explosive, flammable, and toxic substances have recognized
potential major- accident hazards and have taken preventive measures. A major
accident is defined to be a condition that: (1) leads to a serious danger to
people or the environment; (2) results from uncontrolled developments in the
course of an industrial activity; and (3) involves one or more "dangerous
substances." Two levels of analysis and control of a hazardous industrial
activity are established by the guidelines based on the quantity of hazardous
substance stored or processed at an industrial site or in transit: (1)
notification of a potential major hazard and (2) performance of a "Full Safety
Case" analysis.
1. Criteria for Notifiable Installations
The first and lower level of analysis used to identify potential major
hazard installations is defined as the threshold quantity of a hazardous
substance which, if exceeded, necessitates notification to the World Bank of a
potential major hazard. A reporting installation is termed a "notifiable
installation". The list of hazardous substances at quantities above which
notification is required is divided into the following four categories:
a. Very Toxic Substances
b. Other Toxic Substances
c. Highly Reactive Substances and Explosives; and
d. Flammable Substances.
The criteria for the two groups of toxic substances (a and b) are given in
terms of the toxic effects on populations of specified experimental animals.
In certain cases, however, the substances must have physical and chemical
properties capable of entailing major-accident hazards in addition to meeting
the specified criteria. Specifically, the criteria are as follows:
a. Very Toxic Substances
These criteria are independent of the quantities of the substance
stored, or processed, or may be formed by an unwanted by-product reaction.
-11-
-------
A very toxic substance meets one of the following three criteria:
Oral LD_ (mg/kg body weight) of less than 5 in
rats; or
Cutaneous LD,-n (mg/kg body weight) of less than 10
in rats or rabbits; or
Inhalation LC,-n (mg/1; 4 hours) of less than 0.1 in
rats.
or
A very toxic substance, owing to its physical and chemical properties, is
capable of entailing major-accident hazards similar to those caused by
substances meeting one of the above three criteria and, in addition meets one
of the following three criteria:
Oral LD-n (mg/kg body weight) of greater than 5 but
less than 25 in rats; or
Cutaneous LD (mg/kg body weight) of greater than
10 but less than 50 in rats or rabbits; or
Inhalation LC^ (mg/1; 4 hours) of greater than 0.1
but less than 0.5 in rats.
It is unclear exactly what physical and chemical properties are considered
under this second condition, but it is likely that vapor pressure is a main
factor. The guidelines state simply that "this is taken to mean that the
properties are such that the toxic substances could be easily distributed
throughout the environment if containment is breached, for example, a gas or
highly volatile liquid or a solid which might be ejected from a pressurized
reactor."
b. Other Toxic Substances
Quantities for notification specified for nine common substances,
range from as little as 2 metric tons in the case of phosgene to as much as
100 metric tons in the case of anhydrous ammonia. Other unspecified
substances are selected on the basis of being present in quantities exceeding
1 ton and meeting one of the following three criteria:
Oral LD (mg/kg body weight) of greater than 25 but
less than 200 in rats; or
Cutaneous LD (mg/kg body weight) of greater than
50 but less than 400 in rats or rabbits; or
Inhalation LC-n (mg/1; 4 hours) of greater than 0.5
but less than 2 in rats.
-12-
-------
c. Highly Reactive Substances
Again, in this category a list of specific substances, nineteen in
all, is given along with notifiable quantities ranging from 2 metric tons for
hydrogen to 500 metric tons for ammonium nitrates. Although it is not clear,
presumably these substances meet the criterion used to identify other unnamed
potential explosive hazards, namely:
Substances that may explode under the effect of flame
or are more sensitive to shocks or friction than
dinitrobenzene.
d. Flammable Substances
Criteria for inclusion in this section are based upon the class of
flammable substances to which a chemical belongs. The classes are as follows:
(1) Flammable Gases
A gas or any mixture of gases which is
flammable in air and is held as a gas.
Notifiable quantity: 15 metric tons
(2) Liquefied Gases and Flammable Liquids in
Process at Pressure and Temperature Above
Ambient Levels
A substance or any mixture of substances
which is flammable in air and is normally
held in the installation above its boiling
point as a liquid or as a mixture of liquid
and gas at a pressure of more than 1.4 bar
absolute.
Notifiable quantity: 25 metric tons
(3) Refrigerated Liquefied Gas
A liquefied gas or any mixture of
liquefied gases, which is flammable in air,
has a boiling point of less than 0°C, and
is normally held in the installation under
refrigeration or cooling at a pressure of
1.4 bar absolute or less.
Notifiable quantity: 50 metric tons
(4) Highly Flammable Liquids
A liquid or any mixture of liquids not
included in Items 1 to 3 above which has a
flash point of less than 21°C.
Notifiable quantity: 10,000 metric tons
The criteria used to classify a chemical into one of the four
above-mentioned categories is presented in tabular form in Exhibit 4.

2. Criteria for "Full Safety Case" Analysis
The first level of analysis used by industries to determine whether to
report production of hazardous chemicals does not specify a list of
substances, therefore any number of substances meeting one of the four
specified sets of criteria may be notifiable. According to the second (and
higher) level of analysis and control, a company that uses any of 177
specified and general classes of chemicals must perform a "full safety case
assessment" when specified quantities are exceeded. These 177 chemicals are
distinguished by the same criteria that identify notifiable installations; the
quantities of chemicals present identify those installations that must provide
more than simple notification. The toxic substances and highly reactive
substances listed for notification as discussed in the previous section are
also included on this list, with the exception of liquid oxygen (see the
discussion of the EC Dangerous Substances for Storage list). The list of
chemicals is identical to the European Communities Council Directive List,
which is presented in Appendix B, except for the omission of the chemical
0,0-diethyl S-ethylsulphonylmethyl phosphorothioate.

C. California Air Resources Board Toxic Chemical List
and NIOSH/OSHA Pocket Guide to Chemical Hazards
In response to the heightened public concern about the accidental release
of highly toxic substances into the atmosphere and based upon data from the
NIOSH/OSHA Pocket Guide to Chemical Hazards (September 1978), the Air
Resources Board of the State of California has recently developed a list of
104 acutely toxic chemicals. The list of chemicals, together with estimated
emission rates which would result in a NIOSH/OSHA (National Institute for
Occupational Safety and Health/Occupational Safety and Health Administration)
IDLH (Immediately Dangerous to Life and Health) concentration level downwind
from the release points of each chemical, has been circulated to all air
pollution control districts in California to be used as general guidance on
the levels of toxic chemical emissions which might cause significant harm to
the public. Eventually, the Air Resources Board hopes to send out a
questionnaire to the various industries in California, which they have
developed based on production and use of the 104 chemicals. This
questionnaire is designed to determine the quantities of chemicals produced in
California, how the chemicals are used, the methods of storing the chemicals,
the locations of the various plants, and the emergency measures that the
industries have devised to deal with any potential accidents. Data from these
responses will be entered into a computer and analyzed in order to determine
which chemicals warrant further investigation and to what degree. After
prioritizing the list of chemicals, the Air Resources Board intends to inspect
plants that use the listed chemicals, paying particular attention to safety
precautions.
The Air Resources Board used the NIOSH/OSHA Pocket Guide to Chemical
Hazards to compile its list. Because of the emphasis placed on the
information in the guide by the Air Resources Board, a brief description of
the guide will be given here. This guide is a tabular summary of information
and recommendations pertaining to synonyms, permissible exposure limits, IDLH
levels, physical descriptions, chemical and physical properties,
incompatibilities, measurement methods, personal protection and sanitation,
respirator selection, and health hazards including route, symptoms, first aid,
and target organs of 380 specific chemicals for which there are Federal
regulations. These data were collected as part of a joint effort, called the
Standards Completion Program (SCP), between NIOSH and the Department of Labor
in 1974 to develop a series of complete occupational health standards for
those substances with existing permissible exposure limits (Occupational
Safety and Health Act 1970). Several contractors and personnel from various
divisions within both NIOSH and OSHA were involved in the development of the
380 substance-specific draft technical standards and supporting documentation
used to create the pocket guide. Each of the draft technical standards was
evaluated and reviewed by individual representatives from industry, various
professional associations and the joint NIOSH-OSHA SCP steering committee.
The sources of data used included recognized textbooks in the fields of
industrial hygiene medicine, toxicology, and analytical chemistry; articles
from a variety of technical journals, including those identified through
application of computerized literature searches; personal communication with
representatives of industry and labor; meetings with industry associations;
and interviews with individuals knowledgeable about specific industries,
-16-
-------
operations, and processes, and their associated occupational health problems.
Any updated information regarding one of the substances and part of a
recommended occupational health standard completed by NIOSH under its criteria
document development program prior to October 1977 was also incorporated into
the guide. New information on health effects and subsequent revised medical
surveillance recommendations in NIOSH criteria documents completed after
October 1977 will be included in the updated NIOSH/OSHA pocket guide which is
anticipated to be released sometime after September 1985. In addition to
updated information, 17 new chemicals, all carcinogens, will be included in
the guide.
The SCP Committee decided that in order for the new draft technical
standards to cover all safety aspects of the working environment, detailed
requirements concerning the use of respirators were necessary. Thus, IDLH
exposure concentrations of the chemicals were developed with the objective of
ensuring that workers could escape without injury from an IDLH concentration
in the event of failure of respiratory protective equipment. In establishing
IDLH values, the following two factors were taken into consideration:
1. Escape without loss of life or irreversible health
effects. Thirty minutes is considered the maximum
permissible exposure time for escape.
2. Severe eye or respiratory irritation or other reactions
which would prevent escape without injury.
Specific IDLH values were determined conservatively using many different
sources such as IDLH concentrations provided in the AIHA Hygienic Guides,
ACGIH Threshold Limit Values (TLVs), human and animal exposure data and data
for analogous substances when specific toxicological data was lacking.
Because of the reliance on such a variety of sources and the many possible
levels of information available about each substance, the IDLH values vary
widely in their validity.
Of the 380 chemicals currently documented in the NIOSH/OSHA pocket guide,
140 (37 percent) have IDLH levels less than or equal to 2000 ppm, 96 (25
percent) have IDLH levels greater than 2000 ppm, 100 (26 percent) have IDLH
levels cited in mg/m3 units, and 44 (12 percent) have no IDLH level given;
13 of the 44 with no IDLH levels are broad classes of compounds and therefore
no one specific value is applicable. Of those substances with IDLH levels
less than or equal to 2000 ppm, 65 (46 percent) have vapor pressures greater
than or equal to 20 mmHg, 67 (48 percent) have vapor pressures under 20 mmHg,
and 8 have no reported or applicable vapor pressures. Of the 96 compounds
with IDLH levels of greater than 2000 ppm, 49 have vapor pressures of greater
than or equal to 20 mmHg, 43 have vapor pressures less than 20 mmHg and 4 have
no reported vapor pressures. Seventy-two (72 percent) of the chemicals whose
IDLH levels are reported in terms of mg/m3 have vapor pressures less than 20
mmHg, 21 have no reported or applicable vapor pressure and 7 have vapor
pressures greater than 20 mmHg. Of the 44 substances with no IDLH level, 31
(70 percent) have vapor pressures of less than 20 mmHg, 1 (2 percent) has a
vapor pressure of greater than 20 mmHg and 12 (27 percent) have no reported or
applicable vapor pressures. These numbers are summarized in Exhibit 5.

1. Criteria
The California Air Resources Board used an IDLH level of less than or
equal to 2000 ppm and a vapor pressure of greater than or equal to 20 mmHg as
criteria to develop its list of chemicals from the NIOSH/OSHA Pocket Guide.
Many chemicals were included as exceptions to these criteria based upon the
professional judgment of the members of the task force compiling this list.
In fact, 20 of the 104 chemicals on California's list are not included in the
NIOSH/OSHA pocket guide. As discussed above, 65 of the 380 chemicals in the
guide meet the criteria of having an IDLH <2000 ppm and a vapor pressure of
>20 mmHg. Sixty-one of these are included on California's list; the four
which are excluded are ethylene dichloride, nitrogen dioxide, selenium
hexafluoride, and tellurium hexafluoride. According to data in the NIOSH/OSHA
pocket guide, California's list also includes a total of 17 other chemicals
with IDLH levels less than 2000 ppm but with vapor pressures less than 20 mmHg
(10) or unreported (7); 2 chemicals with IDLH levels greater than 2000 ppm and
vapor pressures greater than or equal to 20 mmHg; and a total of 4 chemicals
with IDLH levels reported in mg/m3, 3 with vapor pressures greater than 20
mmHg, 1 with a vapor pressure of less than 20 mmHg. The 3 with vapor
pressures that meet the vapor pressure criterion also meet the IDLH criterion
if the units are converted into ppm. These are crotonaldehyde, phosphorus
pentachloride, and tetramethyl lead. (Note: California reports a 40 ppm IDLH
for tetramethyl lead whereas NIOSH reports an IDLH of 40 mg/m3 which is
equivalent to a 4 ppm IDLH.) The fourth chemical reported in mg/m3 and with
a vapor pressure less than 20 mmHg, anisidine, also meets the IDLH level
criterion after conversion to ppm. Certain inconsistencies occur between the
data in the final California list and the data in the guide. The NIOSH/OSHA
pocket' guide reports data for two chemicals, methyl acetylene and cyclohexene,
as having IDLH levels of 11,000 ppm (based on LEL) and 10,000 ppm
respectively. In contrast, California lists them as having IDLH levels of
1,000 ppm and 300 ppm, respectively. Similarly several other IDLH levels
listed by California differ from those cited in the NIOSH/OSHA pocket guide;
however, in these instances the different values do not affect the chemicals'
abilities to meet the IDLH criterion. Exhibit 5 illustrates the difference
between the NIOSH/OSHA and California listing.

D. New Jersey Department of Environmental Protection
Highly Toxic Substances List
The Division of Environmental Quality (DEQ) in the Department of
Environmental Protection (DEP) in the State of New Jersey has prepared a list
of 86 chemicals (see Appendix B) that, if released into the air in sufficient
quantities, might be capable of causing acute health effects resulting in
death or disability. The development of this list was prompted by the recent
Bhopal, India, disaster involving the release of methyl isocyanate; as such,
the unusual combined properties of methyl isocyanate, namely an extremely high
toxicity, a high volatility (low boiling point), and a relatively high
reactivity, were used as the basic criteria in selecting chemicals for the
list. Furthermore, large quantities of methyl isocyanate were used and stored
at the same location, so the additional criterion of significant usage in New
Jersey was established. After further review and evaluation, the finalized
list will be used as part of an effort to determine if additional control of
the storage and use of highly toxic subtances is necessary in New Jersey.
1. Criteria
The DEQ began by screening chemicals based on their toxicities. A
Threshold Limit Value (TLV) of less than _or equal to 1 ppm was chosen as the
cut-off point. A total of 117 substances were identified by this initial
criterion using the American Conference of Governmental Industrial Hygienists
(ACGIH) handbook, "Threshold Limit Values for Chemical Substances and Physical
Agents in the Work Environment With Intended Changes for 1983-1984."
Next, the list was modified to 86 substances based upon a reactivity
ranking system which used the descriptions of hazardous analysis given in N.I.
Sax's "Dangerous Properties of Industrial Materials" for each of the original
117 chemicals. Substances which were considered the most reactive (i.e.,
those for which a "severe explosion" hazard or "highly dangerous disaster"
hazard were noted) were given a rank of 4 while those substances considered to
represent little or no risk were given a rank of 0. Descriptions of the
possible ranks are presented in Exhibit 6. The 31 chemicals, of the 117, that
had a reactivity rank of 0 were not analyzed further.
The remaining 86 substances, which met both the toxicity and reactivity
criteria, were subsequently examined with respect to their volatility and
usage in New Jersey -- however, these latter two criteria were not used to
limit the size of the list of the chemicals any further; rather, these
criteria may be used to establish relative ranks of the chemicals in terms of
priority for future evaluation according to DEQ. The distribution of
substances with boiling points under 200°F, according to the TLV is shown in
Exhibit 7, and the distribution of usage rates of the chemicals, obtained from
the New Jersey Air Pollution Enforcement Data System (APEDS), is presented in
Exhibit 8. Depending upon which elements of information are deemed to be the
most critical, different subsets of the list can be created. For instance, if
toxicity and "very high" usage were considered to be the most important
factors in evaluating potential accident situations, a list of the 15

in "Dangerous Properties of Industrial Materials" by N.I.
Sax (Van Nostrand Reinhold Company, New York, 1984). Held's
numerical categorization is not based on any parallel
ranking sequence in Sax. Consequently, Held's five
categories are relative only to one another. Sax's
"Disaster Hazards" listing of chemicals focuses on heat
reactivity in an attempt to have information readily
available in case of fire or.other emergency.

chemicals with very high usage ratings would be of top priority. However, a
different list of 11 chemicals would be given precedence if toxicity, boiling
points of less than 200°F, and at least moderate usage in New Jersey were
considered essential in ranking the chemicals. Using these highly toxic/high
use and highly toxic/highly volatile lists, the New Jersey Department of
Environmental Protection has derived a small list of priority chemicals for
further evaluation, which comprises six chemicals which are common to both
lists. This list is shown in Exhibit 9.
DEQ has also organized the list of 86 substances into four different
categories according to the four TLV divisions: less than or equal to 0.05
ppm, equal to 0.1 ppm, between 0.15 ppm and 0.5 ppm, and between 0.6 ppm and
1.0 ppm. These categories were made in order to facilitate further analysis
of the list with possible addition to or deletion from it. Before its list is
finalized, DEQ intends to seek public comment on its methodology used in
selecting the substances and on the particular listings of the substances.
One suggestion that has already been made is that temperature-, humidity-
and/or pressure-sensitive chemicals be included.

E. House of Representatives Bill H.R. 2576
A bill, H.R. 2576, called the "Toxic Release Control Act of 1985" was
introduced to the House on May 22, 1985, by Representatives Wirth, Waxman, and
Florio. As a response to the public concern about the potential occurrence of
a disaster similar to the incidence in Bhopal, India, this list consists of 85
hazardous air pollutants whose emissions are proposed to be regulated by the
U.S. Environmental Protection Agency. The bill also makes provisions for
annual review of and addition to the existing list from several specified
sources of information. Section 306 of the bill identifies a small list of
"extremely hazardous substances" which would be subject to more stringent
control than other substances and makes provisions for additions to this
list. If passed, the Act would repeal Section 112 of the Clean Air Act,
establish inventory and monitoring requirements, and institute a nationwide
public right-to-know law. The Act would apply primarily to stationary
pollution sources (i.e., almost exclusively chemical plants) and also to
mobile sources (i.e., motor vehicles) but would not affect waste disposal
sites regulated under either the Resource Conservation and Recovery Act (RCRA)
or the Comprehensive Environmental Response, Compensation and Liability Act
(CERCLA).
1. Criteria
According to Gerald Dodson of the Subcommittee on Health and the
Environment, who helped to develop the list of hazardous substances in H.R.
2576, three sources were used in the selection of the chemicals: the National
Toxicology Program's (NTP) list of carcinogens, EPA's list of 37 substances or
pollutants that are candidates for review and regulation under Section 112 of
the Clean Air Act, and the American Conference of Governmental Industrial
Hygienists1 (ACGIH) list of industrial chemicals with associated Threshold
Limit Values (TLVs). The criteria for including in the list a chemical from
any of the sources were that (1) the chemical is potentially released into the
air (i.e., high, yet unspecified, vapor pressure) and (2) the chemical is
produced in quantities of at least one billion grams (1100 tons) per year.
Production figures were obtained from the Toxicology Data Bank from the
National Library of Medicine. In addition, chemicals on ACGIH's list were
required to have a TLV of 5 ppm or less. The 85 chemicals in H.R. 2576 that
meet the above criteria are listed in Appendix B.
The bill specifies that within a year of enactment and annually
thereafter, the list of chemicals shall be supplemented by chemicals from
several other sources. In general, the list shall be expanded to include
"each substance which is released into the air and which causes or contributes
to air pollution which may reasonably be expected to result in an increase in
mortality or an increase in serious irreversible, or incapacitating reversible
illness (including substances which are carcinogenic, mutagenic, teratogenic,
neurotoxic, which cause reproductive dysfunction, or which are acutely or
chronically toxic, whether individually or by reason of cumulative or
synergistic effects)." Specifically, the bill calls for the listing of each
of the following substances if the substance is released into the air:
-25-
-------
Each substance listed in the most recent edition of
the "Annual Report on Carcinogens" published by the
National Toxicology Program (NTP) of the United States
Public Health Service;
Each substance designated as a carcinogen by the
International Agency for Research on Cancer (IARC);
Each substance listed as a carcinogen by the
Carcinogen Assessment Group (CAG) of the U.S. EPA; and
Each substance listed in a review by National Cancer
Institute (NCI) scientists published in the Journal of
Toxicology and Environmental Health 8:251-280, Tables 3
through 6 and in subsequent published reviews by NCI
scientists of substances which meet the criteria of the
NTP for significant carcinogenic effect.
Because these sources considered many of the same chemicals, a substantial
amount of overlap exists among the chemicals to be considered from each
source. These sources use criteria which include both acutely and chronically
toxic chemicals. In addition to the automatic listing of the chemicals above,
chemicals from several other sources must be considered in the annual review
process. Again, a preliminary criterion for their listing is that they must
be released into the air. The chemicals from these other sources are as
follows:
Each substance designated as toxic or hazardous by the
Administrator of the United States Occupational Safety
and Health Administration (OSHA) under the Occupational
Safety and Health Act of 1970;
Each substance for which a TLV has been established by
ACGIH;
Each substance listed by the National Fire Protection
Association (NFPA) in "Hazardous Chemicals Data" (NFPA
49);
Each substance listed by the NFPA and rated 2 through
4 as health hazards or rated 3 through 6 as flammability
or reactivity hazards in "Fire Hazard Properties of
Flammable Liquids, Gases, Volatile Solids" (NFPA 325M);
Each substance identified in "Occupational Health
Guidelines for Chemical Hazards" published by the
National Institute for Occupational Safety and Health
(NIOSH);
-26-
-------
Each pesticide which has been classified for
restricted use by the Administrator under Section 3 of
the Federal Insecticide, Fungicide, and Rodenticide Act
or for which the registration has been cancelled or
suspended under Section 6 of the Act; and
Each substance defined as a "hazardous substance"
under CERCLA.
Finally, the bill allows that any person may petition the Administrator of
the EPA to list a substance.
-27-
-------
F. Comprehensive Environmental Response Compensation and
Liability Act (Superfund) Reportable Quantities (RQs)
The hazardous substance list designated under Section 101.14 of the
Comprehensive Environmental Response, Compensation and Liability Act of 1980
(CERCLA) incorporated hazardous substance lists from:
Clean Water Act (Federal Water Pollution Control Act):
Substances designated under Section 311(b)(2)A as
hazardous substances.
Substances designated under Section 307(a) as toxic
pollutants.
Clean Air Act:
Substances designated under Section 112 as hazardous
air pollutants.
RCRA (Resource Conservation and Recovery Act):
Substances designated under Section 3001 as
hazardous wastes.
TSCA (Toxic Substances Control Act)
Chemical substances designated under Section 7.
CERCLA also designates as hazardous substances "... such elements, compounds,
mixtures, solutions and substances which, when released into the environment
may present substantial danger to the public health or welfare or the
environment" under Section 102 of the Act. As of April 1985, 698 hazardous
substances have been incorporated into the CERCLA list from the Clean Water
Act criteria, the Clean Air Act criteria, and RCRA criteria. No substances
have been designated as hazardous under TSCA Section 7 or under Section 102 of
CERCLA.
1. Criteria for Consideration
a. Criteria for Hazardous Substances Listed
in the Clean Water Act (CWA)
Hazardous substances designated under Section 311(b)(2)A of CWA
are those, that when discharged, present "... an imminent and substantial
danger to the public health or welfare, including, but not limited to, fish,
shellfish, wildlife, shoreline and beaches." A two-part process was developed
by the Agency to evaluate conventional, toxic and non-conventional pollutants
that included isomers and hydrates and their compounds.
-28-
-------
As a first step, elements and compounds were evaluated against
toxicological selection criteria as shown in Exhibit 10. Secondly,
candidate substances that met at least one of the toxicological criteria were
examined for discharge potential according to:
1. Past history of discharges;
2. Production quantities;
3. Use and distribution patterns; and
4. Cost of substance.
Candidate substances were designated as hazardous and listed if they had:
1. A spill history; or
2. An annual production equal to or greater than 1 billion
pounds; or
3. An annual production of less than 1 billion pounds, and
are used primarily as pesticides; or
4. An annual production of less than 1 billion pounds and
have relatively low market prices and relatively high
toxicity.
The 279 substances designated as "hazardous" under CWA Section 311 are listed
in 40 CFR 116.
Criteria applied .under Section 307 of CWA establishing toxic effluent
standards were generally stated in the statutory language. In generating the
"toxic pollutants" list under 307, EPA considered:
the toxicity, persistence, and degradability of the
pollutant;
the usual or potential presence of the affected
organisms in any waters;
the importance of the affected organisms; and
the nature and extent of the effect of the toxic
pollutant on such organisms.
Toxic pollutants are defined in Section 502(13) of the Act as "those
pollutants, or combinations of pollutants, including disease-causing agents,
which after discharge and upon exposure, ingestion, inhalation or assimilation
into any organism, either directly from the environment or indirectly by
ingestion through food chains, will, on the basis of information available to
the Administrator cause death, disease, behavioral abnormalities, cancer,

genetic mutations, physiological malfunctions (including malfunctions in
reproduction or physical deformations in such organisms or their offspring)."
Under guidelines later formulated by the Agency, substances were analyzed
specifically for:
(1) Toxicity;
(2) Persistence;
(3) Bioaccumulation, Biomagnification and Bioconcentration;
(4) Synergistic Effects;
(5) Water Solubility;
(6) Extent of Point Source Discharge;
(7) Exposure to Persons, Aquatic Organisms and Wildlife;
(8) Annual Production in U.S.;
(9) Use Patterns; and
(10) Analytical Detection.
One hundred and twenty-six substances, distributed into 65 substance groups,
are identified as toxic under CWA Section 307. They are listed in 40 CFR 401.
b. Criteria for Hazardous Substances Listed
in the Clean Air Act (CAA)
Section 112 of CAA defines a "hazardous air pollutant" as "an air
pollutant to which no ambient air quality standard is applicable and which in
the judgment of the Administrator causes, or contributes to, air pollution
which may reasonably be anticipated to result in an increase in mortality or
an increase in serious irreversible, or incapacitating reversible illness."
No specific quantitative criteria are given for listing of a hazardous air
pollutant under CAA. In the past, potential health hazards of a chemical were
brought to the Agency's attention through scientific reports in journals,
investigations by other agencies, and assertion of concern about a particular
substance by the Environmental Defense Fund. While a standard set of criteria
were not developed for listing a chemical under Section 112, certain classes
of information were consistently explored to support a listing decision:
Health effects;
Epidemiological data;
Animal bioassay data;
Mutagenicity data;
Other regulations or agency data;
No safe threshold;
Linear dose-response relations; and
Significant exposure.
Asbestos, beryllium, mercury, vinyl chloride, benzene, radionuclides and
inorganic arsenic are the seven chemical substances listed as hazardous air
pollutants under CAA, in 40 CFR 61.
-31-
-------
c. Criteria for Hazardous Substances Listed in the
Resource Conservation and Recovery Act (RCRA)
Section 3001 of RCRA defines "hazardous waste" broadly to include
any waste or combination of wastes which, "-- because of its quantity,
concentration, or physical, chemical, or infectious characteristics may:
(a) Cause or significantly contribute to an increase in
mortality or an increase in serious irreversible, or
incapacitating reversible, illness; or
(b) pose a substantial potential hazard to human health or
the environment when improperly treated, stored,
transported, or disposed of, or otherwise managed."
The wastes listed in 40 CFR 261 as hazardous under RCRA fall into one of
the following groups:
Wastes that exhibit any of the following four criteria:1
(1) ignitability -- posing a fire hazard during routine
management;
(2) corrosivity -- ability to corrode standard
containers, or to dissolve toxic components of
other wastes;
(3) reactivity -- tendency to explode under normal
management conditions, to react violently when
mixed with water, or to generate toxic gases; and
(4) extraction procedure (EP) toxicity (as defined by a
specific extraction procedure) -- presence of any
of 14 specified toxic materials within the waste at
levels greater than the maximum concentration
specified in the regulation.
Wastes so acutely hazardous that unlike most wastes
"... they can be considered to present a substantial
hazard whether improperly managed or not."2
Hazardous wastes containing designated toxic
constituents which "have been shown in reputable
scientific studies to have toxic, carcinogenic,
mutagenic or teratogenic effects on humans or other life
forms and include such substances as those identified by
the Agency's Carcinogen Assessment Group."3
1 From 40 CFR 261.21-261.24.
2 From preamble to the Final Rule, p. 33106 (July 26, 1982).
3 From preamble to the Final Rule, p. 33107 (July 26, 1982).
-32-
-------
Over 400 chemicals form the basis for hazardous wastes lists. The
chemicals are found in Appendix VIII of 40 CFR 261. The listed chemicals
appear on one or more of four waste "lists" and can be found in more than one
waste on each list. The lists are:
hazardous wastes from non-specific sources (Section
261.31, F-wastes);
hazardous wastes from specific sources (Section
261.32, K-wastes);
acutely hazardous wastes (Section 261.33(d),
P-wastes); and
toxic wastes (Section 261.33(f), U-wastes).
Criteria for designation of wastes under RCRA are outlined in Exhibit 11.
Any substances added to or deleted from CWA, CAA, or RCRA lists (as long
as the substance appears on one and only one list) are automatically added to
or deleted from CERCLA. Recent additions to the list were published in the
Final Rule dated January 14, 1985, adding wastes containing chlorinated
dioxins, dibenzofurans, and phenols as acute hazardous wastes to the RCRA
list. These additions became effective on July 15, 1985. The list of CERCLA
hazardous chemicals can be found in Appendix B.
2. Criteria for RQ (Reportable Quantity) Determination in CERCLA
In the preamble to the Final Rule on CERCLA Reportable Quantity
Adjustments dated April 4, 1985, which amended RQ values for hazardous
substances listed in Table 302.4 of CERCLA, EPA stated:
"The adjusted RQs do not reflect a determination that a
release of a substance will be hazardous at the RQ level and
not hazardous below that level ... Instead, the RQs reflect
the Agency's judgment of which releases would trigger
mandatory notification to the federal government so that the
government may assess to which (sic) extent, if any, federal
removal or remedial action may be necessary."
CERCLA (1980) established temporary RQ's of one pound for all hazardous
substances that did not have an already determined RQ under Section 311 of the
CWA. For the latter, the CWA RQ's were adopted under CERCLA. Since the
enactment of CERCLA, EPA has been developing a methodology to adjust all of
the CERCLA RQ's. On April 4, 1985, EPA issued a Final Rule adjusting 340 out
of the 698 RQ's for hazardous substances, and a proposed rule for an
additional 105 adjusted RQ's, leaving 253 RQ's for future evaluation and
adjustment.
The 105 proposed RQ's are for substances that have been evaluated for
chronic toxicity and for which the EPA's Carcinogen Assessment Group (CAG) has
determined that no sound evidence of potential carcinogenicity exists. The

Four characteristics identified:

(40 CFR 261.11, A2)
See above
Fatal to humans in low doses or other-
wise extremely toxic however they are
managed. Specific criteria, in the
absence of human data, are: Oral LD$Q
(rat) of less than 50 mg/kg; inhalation
LCso (rat) of less than 2 mg/1; or a
dermal 1*059 (rabbit) of less than
200 mg/kg; or is otherwise capable of
causing or significantly contributing
to an increase in serious irreversible,
or incapacitating reversible illness.
Usually only pure chemicals will meet
this definition, not constituents in a
waste. Examples of "acutely hazardous
waste" are dieldrin, phosgene, and
cyanides.
Carcinogenic, mutagenic, teratogenic,
phytotoxic, organically toxic, or having
potential for bioaccumulation. Examples
of "toxic waste" are toluene, benzene,
saccharin, and formaldehyde.
Some wastes with these properties are
explicitly listed in 261.31 and 261.32.
Any other waste that has any of these
characteristics is defined as hazardous,
See above
Provisions apply only to pure chemicals
and associated containers, etc. A list
of these chemicals is contained in
261.33(e), and they are subject to
regulation in very small quantities.
(Note that most of these chemicals also
appear in Appendix VIII of 40 CFR 261.)
Chemicals with these properties appear in
Appendix VIII. They are regulated in two
ways :
(1) in Sections 261.31 and 261.32,
which list specific hazardous
waste streams and processes; and
(2) in 261.33(f), which lists pure
chemicals that are hazardous
wastes if discarded.
-------
remaining 253 RQ substances require further evaluation of chronic toxicity and
carcinogenicity, thus maintaining the temporary, statutory-mandated RQ values.
The methodology used to assign RQ values under CERCLA Section 302.5 draws
to a large extent on CWA methodology, utilizing the five reporting categories
(reportable quantities) of 1, 10, 100, 1,000 and 5,000 pounds for substances
released and expanding the primary criteria for RQ determination to include:
Aquatic Toxicity;
Mammalian Toxicity;
Ignitability;
Reactivity;
Other Toxic Effects; and
Carcinogenicity.
Each substance was first evaluated quantitatively according to the primary
criteria established, as shown in Exhibits 12 through 18. Some substances
posed a potential hazard in more than one of the primary criteria categories
and thus were assigned multiple RQ values: one for each criterion. The
lowest of these RQ values rather than the average value was assigned to the
substance. Once a substance was evaluated according to primary criteria,
secondary criteria, which evaluate natural dissipation processes, were
applied. Secondary criteria tested for:
Biodegradability;
Hydrolysis; and
Photolysis.
If a substance was shown to naturally dissipate when released into the
environment, the RQ was raised one level.
The following additional criteria for RQ adjustment were under consider-
ation by the Agency, but were not incorporated:
Release history;
Release potential; and
Corrosivity.
The criteria and methodology used in the determination of RQ values for
hazardous substances under CERCLA are described more fully in the Proposed
Rule (dated May 25, 1983) and Final Rule (dated April 4, 1985). Exhibits 13
through 18 were taken from the Final Rule.

-- The minimum effective dose (MED), and
-- The type of effect (e.g., liver necrosis) likely to be caused.
Each factor is given a score on a scale of 1 to 10, 10
corresponding to the greatest potential harm (the smallest MED or
most severe type of effect). RQs are assigned on the basis of
the product of these scores as shown below:

Exhibit 18. Considerations for Developing Adjusted Reportable
Quantities for Substances Identified as Potential Carcinogens
The Agency has collected and evaluated data on the potential
carcinogenicity of CERCLA hazardous substances identified as
known or suspected human carcinogens using the International
Agency for Research on Cancer (IARC) Monographs and the National
Toxicology Program's Annual Report on Carcinogens.
The Agency has developed a procedure for RQ adjustments for
potential carcinogens utilizing a ranking system based on
carcinogenic potency and strength of evidence for carcinogenicity.
No RQ adjustments have yet been proposed or finalized for
potential carcinogens. Therefore, by default, the RQ remains at
the statutory mandated level.

G. Department of Transportation Poisonous Substances List
The Hazardous Materials Regulations of the Department of Transportation
include a Hazardous Materials Table (49 CFR 172.101) listing materials which
represent risks to health, safety, and property during the transport of such
materials. This table presents a hazard class for each material, labeling
requirements, packaging requirements, amount allowed in one package, and
requirements for water shipment.
The types of hazard classes included on the Hazardous Materials Table are:
Forbidden;
Explosives (Class A-C and Blasting Agent);
Radioactive;
Poison (Poison A, Poison B, and Etiologic Agent);
Flammable (gas, liquid, and solid);
Nonflammable gas;
Oxidizer;
Corrosive (liquid and solid);
Irritating;
Organic peroxides; and
Other Regulated Material (ORM-A to ORM-E).
When a material falls into more than one hazard class, the hazard
classification is made according to the following order (49 CFR 173.2):
(1) Radioactive material (except a limited quantity).
(2) Poison A.
(3) Flammable gas.
(4) Nonflammable gas.
(5) Flammable liquid.
(6) Oxidizer.
(7) Flammable solid.
(8) Corrosive material (liquid).
(9) Poison B.
(10) Corrosive material (solid).
(11) Irritating materials.
(12) Combustible liquid (in containers larger than 110 gallons).
(13) ORM-B."
-42-
-------
(14) ORM-A.
.(15) Combustible liquid (in 110-gallon or smaller containers).
(16) ORM-E.
In order to compile a list of toxic substances for comparison with the
acute hazards list, materials listed in the Poison A or Poison B hazard class
on the Hazardous Materials Table were assigned to a DOT Poisons List. In
addition, a number of substances listed in other hazard classes fall into the
Poison B hazard class as well, as indicated by the labeling requirement.
Those substances required to have a poison label, even if the hazard class
listed was not Poison A or Poison B, were included on the DOT Poisons List.
1. Criteria for DOT Poisons
The DOT Hazardous Materials Table includes two hazard classes for
poisons, Poison A and Poison B. (A third type of poison, etiologic agent, is
defined, but because no specific chemicals are assigned to this hazard class,
it was not considered here.) Criteria for poisons are presented below and in
Exhibit 19.
Poison A materials are defined as poisonous gases or poisonous liquids
that present a danger to life when a very small amount of the gas or of the
liquid vapor is mixed with air (49 CFR 173.325). Specific toxicity criteria
are not listed for Poison A substances.
Poison B substances are defined as follows (49 CFR 173.343):
Liquids or solids which, because of their known
toxicity to humans, present a health hazard during
transport; or
Substances that meet one of the following criteria
(unless their physical characteristics indicate, or
previous experience has shown, that the substances will
not cause serious illness or death);
-- An oral dose of 50 milligrams or less per kilogram
of body weight will produce death in at least half
of a group of laboratory rats within 48 hours,
-- Continuous inhalation at a concentration of 2
milligrams or less per liter for one hour or less
will produce death in at least half of a group of
laboratory rats, and such a concentration is likely
to be encountered by humans when the substance is
used, or

2. DOT Poisons List
The poisons list compiled from the Hazardous Materials Table contains
153 chemicals, presented in Appendix B. Non-specific classes of substances
(such as mercury-based pesticides and unspecified drugs and medicines) and
substances without CAS numbers were not included on the list. Twelve of the
substances on the list were classified as Poison A substances; the remaining
141, as Poison B substances. Of the Poison A substances, six were also
flammable gases, and two others were oxidizers as well as poisons. Of the
Poison B substances on the list, 3 were flammable gases, 15 were flammable
liquids, 5 were oxidizers, 2 were nonflammable gases, 2 were flammable solids,
1 was corrosive, and 1 was both a non-flammable gas and an oxidizer. Thus,
approximately 25 percent of the substances on the poisons list present other
types of hazards as well as being poisonous.

H. Philadelphia Air Pollution Control Board
Toxic Air Contaminants List
In 1981, the Air Pollution Control Board of the Philadelphia Department of
Public Health approved Air Management Regulation VI, Control of Emissions of
Toxic Air Contaminants. This regulation includes a list (Schedule A) of 99
substances, which must be reported if emitted into the air. A second list,
Schedule B, lists five substances which are considered to be toxic air
contaminants but are excluded from the reporting requirement because reporting
procedures under other regulations are considered adequate.
1. Criteria for Toxic Air Contaminants
Although the criteria used to develop the Schedule A list of toxic air
contaminants are not specified, a number of factors were considered:
Risk of immediate harm to human health, at
concentrations likely to be encountered in the community;
Carcinogenicity, as proven by epidemiological studies
in human and animal populations;
Suspected carcinogenicity as shown in human
epidemiological studies, animal laboratory studies, or
other experimental studies;
Mutagenicity and teratogenicity as proven through
human,.animal, or experimental studies;
Bioaccumulative effects in humans and the environment;
Toxicity findings of the Environmental Protection
Agency, the Occupational Safety and Health
Administration, or other such agencies;
The extent to which the substance is likely.to be
found in industries in Philadelphia; and
Other factors as necessary.
The Schedule B list consists of five substances that meet the above
criteria and are defined as pollutants by the Environmental Protection Agency:
Carbon monoxide;
Sulfur dioxide;
Ozone;
Nitrogen dioxide; and
Total suspended particulates.
-46-
-------
2. List of Toxic Air Contaminants
The Philadelphia list of toxic air contaminants contains a combined
total of 104 substances on Schedule A and Schedule B (see Appendix B). Two of
these are general categories (particulate polycyclic aromatic hydrocarbons on
Schedule A and total suspended particulates on Schedule B). Some of the
listings on Schedule A include broad chemical classes; ten listings are for
elements and their (unspecified) compounds, and two are for organic chemicals
and their isomers.
The major concern in the development of the Schedule A list, according to
a committee report,* was with chronic low-level exposure in the community
and the associated health effects -- because it was believed that any acute
high-level exposure would probably be the result of an emergency situation and
would be responded to directly. Therefore, the list is weighted toward known
and suspected carcinogens. Fifty-eight of the chemicals on the list are
considered possible carcinogens.5 Thirty-nine of the listed chemicals are
pesticides;5 some of these are also possible carcinogens. Eleven chemicals
are on the list because of local emission rates or other local concerns.5

I. Union Carbide Corporation Industrial Hygiene Sampling
and Monitoring Program List
Union Carbide Corporation (UCC) created an industrial hygiene monitoring
program to be implemented at the Institute, West Virginia plant in 1984. This
program uses a list of hazardous chemicals to aid in assigning, monitoring and
sampling priorities. The list contains 63 chemicals, 12 dusts and fumes, and
six physical stresses (heat stress, lighting, radiation, sanitation, noise,
and ventilation) that UCC believes may be present at its Institute plant. It
is important to note that this list, specific to one location, is too
restrictive to be used as the basis for developing a national list.
1. Criteria
A classification system is applied to individual chemicals by assigning
ratings. The ratings range from 1 to 4 with 4 being the most hazardous.
Although the available information is ambiguous, it appears that if a chemical
meets any of the criteria assigned to a rating level, it falls into that
level. The rating system is:
Rating 4 -- Substances that:
1. Are known human carcinogens.
2. Result in mutagenesis, teratogenesis, or fertility impairment in
humans.
3. Result in irreversible central nervous system disturbances.
4. Result in cumulative irreversible long-term organ toxicity.
5. Are predominantly fast-acting and can produce major injury.
6. Have OSHA, ACGIH, or UCC standards (whichever is lower) including
permissible exposure limits (PEL) of less than 5 ppm or less than
0.1 mg/m3 as TWA0 (time weighted average for normal 8-hour
o
work day).
Rating 3 -- Substances that:
1. Are suspected human carcinogens, mutagens and teratogens (animal).
2. Result in hematologic disturbances.
3. Result in respiratory or skin sensitization.
4. Produce narcosis.
5. Have PEL's from 5 to 25 ppm or 0.11 to 1.0 mg/m3 as TWA..

Rating 2 -- Substances that:
1. Produce severe irritation of the skin, eyes, or respiratory system.
2. Are anoxiants.
3. Have PEL's from 26 to 200 ppm or 1.1 to 5.0 mg/m3.
Rating 1 -- Substances that:
1. Are classified as simple asphyxiants or nuisances.
2. Have generally low risk effects.
3. Have PEL's greater than 200 ppm or greater than 5 mg/m3.
Thus, the rating scheme is based upon health effects that can be caused as
a result of continuous low-level exposure or short-term exposure. A
determination of the frequency of air sampling necessary for a given substance
is based upon the consideration of three factors: temporal pattern of
exposure (routine or frequent); hazard rating (1-4); and level of in-plant
exposure compared to the PEL. After consideration of these factors, one of
four sampling plans would be assigned to the given exposure scenario: 0-3
months; 3-6 months; 12 months; or 24 months (at a minimum all areas with
potential for employee exposure must be sampled every 24 months). For
example, a-substance with a hazard rating of 4 and routine exposure would be
sampled every 0-3 months regardless of the level of in-plant exposure. At the
other end of the spectrum, a substance with a hazard rating of 1, routine
exposure, and in-plant exposure greater than or equal to the PEL would be
sampled every 12 months.
According to Union Carbide, chemicals potentially present at UCC plants
with a rating of 4 are: acrolein, acrylonitrile, aldicarb oxime, aniline,
chlorine, chloroform, ethylene oxide, formaldehyde, glutaraldehyde, hydrogen
peroxide, landrin (BROOT), methomyl, methomyl oxime, methyl isocyanate,
Z-phenol, polychlorinated biphenyls (PCB) around transformers, phosgene,
TEMIK, and TDI. Hazardous dusts and fumes with a rating of 4 include
asbestos, catalyst (silver and silver oxide), coal dust, metals (lead,
mercury, cadmium, copper) at maintenance shops, welding fumes, and ZECTRAN.

J. Unregulated Air Toxins List Identified by Congressman Waxman
Congressman Henry Waxman (D.,California), Chairman of the House Health and
Environmental Subcommittee, requested 86 chemical companies to identify
substances that are leaked or vented into the air from new chemical plants and
that meet certain criteria relating to hazards. Each company submitted a list
of air contaminants it believed to be extremely hazardous. Responding
companies were requested to evaluate a chemical's hazards with regard to Union
Carbide Corporation's (UCC) rating system and to report those chemicals that
would receive a rating of 4, or "extremely hazardous", under the UCC system.
The responses generated a list of 196 compounds.
It should be pointed out that gathering information on substances "leaked
or vented into the air" may produce a potpourri of release scenarios from the
low-level routine or continuous releases to high level, accidental, one time
releases.
According to Congressman Waxman's press release, the chemicals on the list
can cause health effects as the result of long-term, low level continuous
exposure or short-term exposure. Chemicals with a rating of 4 under the UCC
system include those which:
1. Are known human carcinogens, or
2. Result in mutagenesis, teratogenesis, or fertility impairment, or
3. Result in irreversible central nervous system disturbances, or
4. Result in cumulative irreversible long term organ toxicity, or
5. Are predominantly fast-acting and can produce major injury, or
6. Are covered by workplace standards (OSHA, UCC, or ACGIH) with
permissible exposure limits of less than 5 parts per million or
less than 0.1 milligrams per cubic meter as a time weighted
average over eight hours.

APPENDIX A: SUMMARY EXHIBITS OF CRITERIA FOR HAZARDOUS CHEMICALS LISTS
FROM TEN DOMESTIC AND INTERNATIONAL ORGANIZATIONS
These summary exhibits must be used in conjunction with the text. They
summarize for quick reference the criteria used to establish chemical hazard
lists from ten national and international agencies. Appendix A-l summarizes
the criteria for eight lists: European Communities, World Bank, California,
New Jersey, H.R. 2576, CERCLA, DOT Poisons, and Philadelphia. Appendix A-2
summarizes the criteria for the Union Carbide and Unregulated Air Toxins
Lists. The EPA criteria may be found in Exhibit 2 of this document.
The headings for the Appendix A-l summary exhibit have been generalized as
much as possible to encompass the various criteria used to establish the
lists. Certain of the lists have very specific categories for classifying
hazardous chemicals, such as the European Communities (EC) list with seven
separate categories, the World Bank list with eight separate categories, and
the DOT list with two categories. Other lists have essentially one category,
such as the California and New Jersey lists. The CERCLA, H.R. 2576, and
Philadelphia lists have specific criteria reflecting their diverse purposes.
In reading the Appendix A-l exhibit, attention should be given to the
words and and or in those categories with multiple factors for
classification. For example, the EC Very Toxic Substances b. category
specifies toxicity values and physical-chemical properties. Toxicity values
of- an LDC_, oral, of £25 mg/kg or an LD , cutaneous, of £400 mg/kg,
jU _>U
plus certain physical-chemical properties allows classification in this
category.

I. INTRODUCTION
This analysis was performed in support of EPA's Chemical Emergency
Preparedness Program: Interim Guidance (November, 1985). One element of this
program was the provision of guidance to local communities for the purpose of
identifying industrial facilities that may present a public health risk if an
accidental release of an acutely toxic chemical occurs. One aspect of this
guidance was the selection of a set of toxicologic criteria to identify
chemicals that may cause serious human health effects from short-term
exposures such as accidental air releases. Another aspect of the guidance was
the preparation of a sample list of chemicals meeting these criteria. This
sample list of chemicals, EPA's Acutely Toxic Chemicals List (ATCL), was
compiled by selecting chemicals from an automated, on-line toxicologic
database (National Institute for Occupational Safety and Health, Registry of
Toxic Effects of Chemical Substances (RTECS), National Library of Medicine's
current Medline file), that met the toxicity criteria and were on the 1977
TSCA inventory or the current EPA list of active pesticide ingredients. (See
the Interim Guidance Document for further details).
EPA recognizes that toxic chemicals can be identified by innumerable sets
of criteria, depending upon the purpose. Thus, as part of the effort to
select a set of toxicologic criteria and construct a sample list, EPA
conducted a qualitative and quantitative analysis of lists of toxic chemicals
developed by other domestic and international organizations. The qualitative
analysis examined the purpose of each list, general criteria (toxicologic,
physical chemistry, production, etc.) used to construct each'list, and the
actual chemicals and classes of chemicals on each list. The results of this
qualitative analysis may be found in a document entitled "Purposes of and
Criteria for Development of Chemical Hazard Lists from Ten Domestic and
International Organizations," draft document dated July 25, 1985, and the
final document dated December 31, 1985. The various criteria used to develop
the lists are detailed in that document and will not be presented here. Note
that EPA's purpose was the identification of chemicals toxic to humans after
acute exposures. Several of the other lists were not specifically designed
for this purpose and also included chemicals that were toxic after chronic
exposures.
The analysis presented in this document is a quantitative comparison of
EPA's Acutely Toxic Chemicals List and each of the ten domestic and
international lists described above. These lists are the European Communities
Council Directive Chemical Hazard (EC) List*; World Bank Chemical Hazard (WB)
List*; the California Air Resources Board Toxic Chemicals (California) List;
New Jersey Department of Environmental Protection Highly Toxic Substances (New
Jersey) List; House of Representatives Bill H.R. 2576 (HR 2576) List;
Comprehensive Environmental Response, Compensation and Liability Act (CERCLA/
Superfund) Reportable Quantities (RQs) List; Department of Transportation
* For comparison purposes, the EC list and WB list are treated as one list
because they only differ by one chemical. The EC list contains the additional
chemical 0,0-diethyl S-ethylsulphonylmethyl phosphorothioate. The EC list was
used for the comparison. Thus, nine lists are analyzed in this document.
-------
Poisonous Substances (DOT) List; Philadelphia Air Pollution Control Board
Toxic Air Contaminants (Philadelphia) List; Union Carbide (UC) List; and the
Unregulated Air Toxins (Air Toxins or Air Tox) List as prepared by Congressman
Henry Waxman's (D., California) office. This quantitative analysis is not an
attempt to produce a 100% match between EPA's ATCL and any of the other
lists. It simply provides a numerical basis for comparing the outcome of
several different approaches to identifying toxic chemicals.
II. QUANTITATIVE ANALYSES
The first quantitative analysis completed was a direct comparison of EPA's
ATCL to each of the nine other lists by Chemical Abstract Service (CAS)
registry number (Exhibit 1). EPA's ATCL does not include any general chemical
classes but rather all entries on the list are specifically named chemicals.
Some of the other lists named general classes of chemicals as one entry on a
list. For comparison purposes, the chemicals were considered common to both
lists if EPA's ATCL contained at least one member of a general class of
chemicals named on another list. Data in Exhibit 1 present the number of
chemical names on each list, the number of chemicals in common with the ATCL,
and the number of chemicals not on the ATCL.
The second quantitative analysis examined those lists with purposes that
were, in part, comparable to the EPA's purpose. These other lists with a
comparable purpose were the EC/WB, New Jersey, California, H.R. 2576, Union
Carbide, and Unregulated Air Toxins. The remaining lists, CERCLA, DOT, and
Philadelphia, will not be part of this analysis because their purposes were
distinguishable from the purpose of the Chemical Emergency Preparedness
Program and the selection criteria would not be appropriate for comparison
with the ATCL.
Although these six lists were created for purposes similar to EPA's they
were generated from different criteria. The EC/WB relied upon acute mammalian
toxicity and some physical-chemical properties such as ignitability,
reactivity, and explosivity; California relied upon vapor pressure and the
Immediately Dangerous to Life and Health (IDLH) measure established by the
National Institute of Occupational Safety and Health (NIOSH); New Jersey
relied upon a reactivity ranking and a Threshold Limit Value (TLV) of less
than one part per million (ppm); Union Carbide relied upon a variety of
chronic and acute toxicity end-points and the potential worker exposure at
their facility in Institute, West Virginia; Unregulated Air Toxins relied upon
Union Carbide's criteria; and H.R. 2576 relied upon the National Toxicology
Program's (NTP's) list of carcinogens, EPA's list of 37 substances that are
candidates for regulation under Section 112 of the Clean Air Act, the American
Conference of Governmental Industrial Hygienist's (ACGIH's) list of TLV's, a
potential for air release, and annual production of at least 1100 tons. Thus,
with the exception of the EC/WB and California, the other lists relied upon
toxicity measures that evaluate adverse effects from chronic low-level
exposure as well as short-term exposures. EPA's ATCL is specific for toxicity
following short-term exposures.

The number of names in common with ATCL was determined by matching CAS
registry numbers on each list against the ATCL. For certain of the lists,
the CAS number had to first be determined.
These numbers include chemicals for which CAS numbers could not be
identified.
The EC/WB and Philadelphia lists included categories of chemicals
without CAS numbers. Certain of these categories were matched with
chemicals on the ATCL.
The names on the list included isomers and related chemicals, thus
requiring 9 additional CAS numbers to be added to the original 104 names,
for a total of 113 substances and chemical categories to be matched to the
ATCL.

-------
The EC/WB list included chemicals based on explosivity, flammability, and
reactivity characteristics. EPA has not listed such specific chemicals, but
concern for such chemicals is included in the Chemical Emergency Preparedness
Program Interim Guidance Document by reference to the Department of
Transportation's criteria for identifying explosive, reactive, flammable, and
corrosive chemicals.
For the six lists with purposes similar to EPA's, i.e., California, EC/WB,
New Jersey, Union Carbide, H.R. 2576 and Air Tox, an evaluation of individual
chemicals not appearing on EPA's list (ATCL) was conducted. Chemicals from
these six lists not appearing on the ATCL were evaluated for their ability to
meet EPA's criteria for acute mammalian toxicity and current production.
Acute toxicity data on individual chemicals were extracted from RTECS.
Current production was defined as inclusion on the 1977 TSCA Inventory or
EPA's current list of active pesticide ingredients. The results of this
analysis are presented in Exhibit 2. All chemicals not appearing on the ATCL
that were identified by EPA as being in current production do not meet EPA's
toxicity criteria.
The third quantitative analysis was an examination of the frequency of
naming a chemical to one or more of the other lists of (a) the 766 unique
chemicals that did not appear on the ATCL, (b) the 256 unique chemicals that
did not appear on the ATCL but did appear on the six lists with purposes
similar to EPA's Chemical Emergency Preparedness Program, and (c) the 402
chemicals on the ATCL.
The 766 chemicals represent a variety of chemicals that were named to a
list because of their acute and/or chronic toxicity. As shown in Exhibit 3,
over 75 percent of the 766 unique chemicals were named on one and only one of
the other nine lists. The chemicals appearing on three or more lists are
presented individually in Exhibit 4.
The six lists with purposes similar to EPA's Chemical Emergency
Preparedness Program contained a combined total of 256 unique chemicals that
did not appear on EPA's ATCL (Exhibit 5). Of these 256 chemicals, 27 percent
were named on two or more of the six lists.
The 402 chemicals on EPA's ATCL were analyzed for the frequency of
occurrence on the other nine chemical lists. As data in Exhibit 6
demonstrate, of the 402 chemicals on the EPA's ATCL, 209 chemicals or over 50
percent appeared on at least one other list, while 38 chemicals appeared on 5
or more lists. The five chemicals that appeared on 8 lists are acrolein,
acrylonitrile, chlorine, methyl isocyanate, and phosgene.
All of the 766 chemicals not on the ATCL, but appearing on at least one of
the other lists, are identified by name and CAS number in the Appendix. The
list(s) on which each chemical was named is also indicated in the Appendix.

Current production is defined by inclusion on 1977 TSCA Inventory or
EPA's List of Active Pesticide Ingredients.
The numbers in parentheses are those chemicals with acute mammalian
toxicity data meeting EPA's toxicity criteria.
Six chemical categories could not be matched to the ATCL.
Chemicals in the categories explosive, flammable, reactive, and/or
corrosive were included in the EPA Chemical Emergency Preparedness Program
by reference to the DOT regulations (see Chemical Emergency Preparedness
Program: Interim Guidance Document, November 1985).
These criteria do not apply to this list.

For comparison purposes, the EC and WB lists have been analyzed together
and the number of chemicals counted only once. The EPA's ATCL (402) have
not been included in the total count. The lists analyzed were EC/WB,
California, New Jersey, H.R. 2576, CERCLA, DOT Poisons, Philadelphia,
Union Carbide, and Unregulated Air Toxins.
This is the number of other lists on which each chemical is named. The
numbers of chemicals on the lists are exclusive tabulations, i.e., 580
chemicals appeared on only one list, while 186 chemicals appeared on two
or more lists, etc.
The number was determined by unique CAS numbers. Categories and classes
of chemicals have not been included in this tabulation.
The specific chemicals and their CAS numbers may be found in Exhibit 4.
