EXECUTIVE STJWAKY
The purpose of this report is to provide the U.S. Environmental Protection
Agency with the technical background required to adjust the reportable
quantities (RQs) of hazardous substances designated in Section 101(14) of the
"Comprehensive Environmental Response, Compensation and Liability Act of 1980"
("CERCLA," or "Superfund").
BACKGROUND
Section 103* requires immediate notification fron any person in charge of a
vessel or an offshore or an onshore facility who releases an amount of a
hazardous substance equal to or greater than its RQ. Under Section 102(b),
the RQ of any hazardous substance defined in Section 101(14) is 1 Ib unless a
different RQ has been established pursuant to Section 311(b)(4) of the Federal
Water Pollution Control Act. This is the statutory RQ for each hazardous
substance unless and until the Administrator of the EPA promulgates
"regulations establishing that quantity of any hazardous substance the release
of which shall be reported** pursuant to" Section 103. CERCIA also permits
EPA to establish a single RQ for each hazardous substance regardless of the
environmental medium into which the substance is released.
* Unless otherwise specified, section numbers refer to CERCIA.
** The terms "notification" and "report" are used interchangeably in this
document.
ES-1
-------
EPA is proposing to adjust the RQs of the hazardous substances designated in
Section 101(14). This report addresses the strategy for adjusting the RQs of
the 607 hazardous substances in Section 101(14). A companion report discusses
the economic and regulatory effects of this strategy.
TOE SECTION 101(14) LIST
CERCXA Section 101(14) defines hazardous substances as:
A. Any substance designated pursuant to Section 311 (b) (2) (A) of the
Federal Water Pollution Control Act,
B. Any element, compound, mixture, solution, or substance designated
pursuant to Section 102 of CERCLA,
C. Any hazardous waste having the characteristics identified under or
listed pursuant to Section 3001 of the Solid Waste Disposal Act,
D. Any toxic pollutant listed under Section 307(a) of the Federal Water
Pollution Control Act,
E. Any hazardous air pollutant listed under Section 112 of the Clean Air
Act, and
F. Any iitininently hazardous chemical substance or mixture with respect
to which the Administrator has taken action pursuant to Section 7 of
the Toxic Substances Control Act.
Accordingly, the 297 chemicals designated as hazardous substances pursuant to
Section 311 of the Clean Water Act (CWA), and listed in 40 CFR Part 116, are
hazardous substances for purposes of Superfund. So are the 65 compounds and
classes of compounds that have been listed in connection with the consent
decree pursuant to CWA Section 307(a) and the 126 priority pollutants
ES-2
-------
developed in implementing Section 307(a) of the Clean Water Act. The seven
hazardous air pollutants that have been identified pursuant to the Clean Air
Act (CAA), Section 112, are also hazardous substances for Superfund purposes.
No imminently hazardous chemical substances have yet been published pursuant
to Section 7 of the Toxic Substances Control Act. All of the hazardous wastes
that have been identified in 40 CFR Part 261 pursuant to Section 3001 of the
Solid Waste Disposal Act (more commonly referred to as RCRA) are also
hazardous substances. These wastes include the 233 U-wastes, the 107
P-vrastes, the 13 F- and 76 K-waste streams, and the unlisted wastes designated
only because they exhibit the characteristic of ignitability, corrosivity,
reactivity, or extraction procedure (EP) toxicity.
The CERCLA Section 101(14) list consists of the following.
1. Section 311 (CWA) (40 CFR Part 117) - 297 chemicals with PQs assigned
based on aquatic toxicity.
2. Section 307(a) CWA - 65 compounds and classes of compounds are
designated under CWA Section 307(a). The EPA has identified 126
specific compounds as priority pollutants that fall within these 65
compounds and classes of ccmpounds. Under CERCLA, RQs have been
adjusted as indicated in this report only for the 126 specific
priority pollutants, because some of the broad classes encompass
hundreds of specific ccmpounds. Therefore it would be virtually
impossible for the Agency to develop a reportable quantity for a
generic class of compounds that would take into account the
characteristics of all the specific compounds.
3. Section 112 (CAA) - Seven chemicals (six of which are also on the CWA
Section 307(a) list) are designated under Section 112 of the CAA.
See 40 CFR Part 61. (National Emission Standards have been
promulgated only for asbestos, beryllium, mercury, and vinyl
chloride.)
ES-3
-------
4. TSCA - no entries.
5. Section 3001 of RCRA - 40 CFR Part 261, consisting of
A. Specific chemical wastes:
"P" List - 107 acute hazardous wastes
"U" List - 233 toxic wastes
B. Waste streams:
"F" List - 13 hazardous wastes from nonspecific sources
"K" List - 76 hazardous wastes from specific sources
The entire CERCLA Section 101(14) list comprises a total of 607 identifiable
separate substances. Many chemicals and specific chemical wastes are
duplicates, although they appear in the various lists under different names.
In addition to these 607 hazardous substances, there is another group of
wastes in RCRA, the so-called unlisted or ICRE wastes (Ignitability,
Corrosivity, Reactivity, EP Toxicity) that meet specific tests described in 40
CFR Part 261. The number of substances that fall into this category cannot be
quantified. The strategy for adjusting RQs to be discussed herein also
applies to these wastes.
CANDIDATE STRATEGIES
Various strategies may be considered for assigning RQs, as follows:
ES-4
-------
Preferred Strategy
Adjust the Section 101(14) statutory RQs using Selected Criteria Processing
(SCP), described in more detail in Section 2 of this report. SCP consists of
selecting six primary criteria for adjusting RQs: ignitability, reactivity,
carcinogenicity, aquatic toxicity, acute mammalian toxicity (oral, dermal,
inhalation), and chronic toxicity. (Chronic toxicity, for the purposes of
this report, is defined as toxicity due to repeated or continuous exposure
from a single release or multiple releases of a designated hazardous
substance.) For each criterion, a five-tiered rating scale is set up
corresponding with RQ values of 1, 10, 100, 1000, and 5000 Ibs (X, A, B, C,
D). Since this five-tiered system was successfully used in the CWA and the
regulated community is familiar with it, CERCLA uses this methodology. Unlike
the CWA, GERCXA addresses all media, not only water. Therefore, while the
strategy selected to adjust the RQs of the designated hazardous substances
pursuant to Section 101(14) of CERdA was based on the precedence established
in assigning RQs pursuant to the CWA, instead of using aquatic toxicity as the
sole criterion for establishing RQs, health and welfare effects for other
media were also used to adjust the RQs. Each hazardous substance is evaluated
according to the primary criteria and an RQ value is determined for each
applicable criterion.
The "primary criteria" RQ for each hazardous substance is the lowest value of
all the applicable criteria. For example, if for a particular hazardous
substance its ignitability corresponds to an RQ of 1000 Ibs, its chronic
toxicity to an RQ of 5000 Ibs, its aquatic toxicity to 10 Ibs, its mammalian
toxicity to 100 Ibs, and its reactivity to 1000 Ibs, the proposed RQ is 10
Ibs, based on its aquatic toxicity. Carcinogenicity is not being used at
present to determine RQs pending evaluation of the Carcinogen Assessment
Group's (CAG) methodology.
ES-5
-------
The Agency then evaluates each substance according to biodegradation,
hydrolysis, photolysis. The "primary criteria" PQ is then raised one level if
an analysis of these secondary criteria indicates that the substance naturally
dissipates when released into the environment by biodegradation, hydrolysis,
or photolysis.
This strategy was chosen for adjusting the RQs of the 607 hazardous
substances, and is referred to as the SCP strategy.
To date, EPA has fully assessed 64 of 224 substances that must be assessed for
chronic toxicity.
The advantages of the SCP strategy are numerous. First, it is technically and
scientifically sound. Much of the germane data are readily available. It
provides flexibility in that as new data are generated, the RQ can be adjusted
if necessary. The strategy is simple, understandable, workable, and
implementable, since the regulated ccmmunity is familiar with the notification
scheme under the CWA.
A modification of the SCP strategy which was also considered, but not used to
adjust the RQs, is to adjust the RQ to 1 Ib for those substances that are
clearly extremely hazardous and adjust all others to some much larger RQ such
as 1000 Ubs. This approach would have the advantage of providing a rather
simple system of adjusting RQs. It suffers from the rather severe
disadvantage, however, that many substances would likely fall in an
intermediate range between those that are obviously extremely hazardous and
those that pose relatively little, but yet significant, hazard. It would
therefore be difficult in many cases to make the decision whether the
particular hazardous substance should fall in the category of a 1-lb RQ or a
1000-lb RQ.
ES-6
-------
Summary of Adjustments
The table below suntnarizes the proposed RQ adjustments. The number of
substances is given for each of five categories. In addition, the number of
substances that remain to be assessed for chronic toxicity and carcinogenicity
is given.
No. of Substances with Specified RQs
RQ (Ibs) Statutory RQ Proposed RQ
1 334 46
10 27 40
100 .41 89
1000 111 95
5000 94 91
CARC TEA 86
CHRON TEA 91
CARC/CHRON TEA 69
Of the total of 607 designated hazardous substances, RQs have been adjusted
for 361 under CERdA, raising 162, lowering 28, and leaving 171 others
unchanged. Adjustments to the statutory RQs for the remaining 246 substances
will be proposed when further analysis is complete (if such adjustments are
deemed appropriate).
Alternate Strategies
1. Leave all RQs as statutorily defined. For all hazardous substances
except the 263 whose RQ pursuant to the OtfA Section 311 is larger
than 1 Ib, the RQ would then remain at 1 Ib. Reporting all releases
at or above 1 Ib would not only subject the regulated community to an
ES-7
-------
increased reporting burden, but might also flood the National
Response Center with many telephone calls that would rot warrant
federal response.
2. Adapt RQs based on administrative feasibility. The Senate Committee
Report (96-848) states (p. 29):
"The provision intentionally omits from the requirement to determine
"reporting" quantities any reference to harm or hazard. A single
quantity is to be determined for each hazardous substance, and this
single quantity requires notification upon release into any
environmental medium. It would be virtually impossible to determine
a single quantity applicable to all media while at the same time
linking such quantity to any subjective concept of harm.
"It is essential that such quantities be relatively simple for those
subject to notification requirements to understand and comply with.
Since releases in such quantities trigger notification requirements,
but do not, in and of themselves, give rise to other liabilities
under this Act, the President's broad discretion to select quantities
will not unfairly burden those persons subject to the Act.
"In determining reportable quantities under this paragraph, the
President may consider any factors deemed relevant to administering
the reporting requirements or the President's other responsibilities
under this Act. Administrative feasibility and practicality should
be primary factors. In addition, the President may revise such
regulations from time to time if under-reporting or over-reporting is
occurring under existing regulations."
EPA is considering basing the RQ adjustments on technical criteria,
while leaving open the option of further revision of the RQs based on
administrative feasibility as experience dictates. Administrative
considerations are discussed at greater length in Section 4.
3. Adjust the RQs for all the hazardous substances based primarily on
aquatic toxicity considerations. This Aquatic Toxicity approach has
the advantage of being not only consistent with, but identical to
that used in arriving at the RQs for the CWA Section 311 hazardous
substances. The Agency has determined that additional
characteristics that may pose environmental harm should be taken into
ES-8
-------
account.
4. Adopt suitable scenarios to arrive at the EQ. This alternative
strategy employs part fact and part assumption to arrive at an
appropriate RQ based on the potential of the hazardous substance to
cause harm via multimedia pathways. Scenarios are useful ways to
relate basic data to a set of assumed conditions, events, and
circumstances. The scenario is built up by assuming reasonable
conditions for the release and reasonable conditions that produce a
threat to human health or welfare or the environment. The choice of
the conditions is at the discretion of the individual or group
developing the scenario, and therein lies the weakness of the
scenario approach. Broad- agreement that a particular scenario is the
most realistic that can be developed is not likely.
5. Use the detailed results of fate and effects research on each of the
designated hazardous substances to assign an RQ based exclusively on
the results of the research. This approach involves a complete
understanding of how each designated hazardous substance interacts
with the environment, what products may be formed under various
circumstances, and how the designated hazardous substance and its
environmentally produced products each potentially affect the public
health or welfare or the environment. A major disadvantage of the
fate and effects approach is that it demands extensive data
collection and analysis. The data required are not available to the
Agency. Furthermore, pursuing this approach for RQ adjustments would
be very resource-intensive and time-consuming.
6. Develop a hazard index that takes into account all the individual
potential hazards to which releases of a hazardous substance may
expose the public or the environment. The hazard index is a
composite scoring system designed to assess the relative potential
threat to human health and to the environment of chemical substances
-------
released to the air, water, and soil. The system consists of
delineating various rating factors used to examine the types of
hazards that may result, and, to the extent possible, the degree of
hazard or potential for hazard. Each rating factor has a defined
rating scale by which chemicals receive numerical scores based on
known data. The rating factors are combined in an equation or
algorithm format to arrive at a single number that is used to rank a
chemical relative to other chemicals processed through the same
equation or algorithm. This scheme is analogous to that employed in
producing a site-ranking model for determining remedial action
priorities among uncontrolled hazardous waste sites.
This scoring technique has seme very definite advantages over other
approaches: (a) the hazard index can relate to all media, (b) it can
include a wide range of criteria that link the substance to a concept
of potential harm or hazard, (c) it can provide an impartial,
objective, and uniform mechanism that can be applied to a wide
variety and to a large number of hazardous substances, and (d) it is
a simple and direct way to evaluate a large data base with respect to
intrinsic properties.
The major disadvantage of the hazard index approach is that many
?
individual combinations can be set up involving different judgments
of the relative importance of single hazard factors. Any one finally
selected combination connecting the individual rating factors may be
subjected to logical criticism on the basis of a different perception
of the relative importance of those factors. Rorther, gaps in the
data base may make it difficult, if not impossible, to compare all of
the designated hazardous substances on the same objective basis.
ES-10

SECTION 1
INTRODUCTION
The release of a hazardous substance in an amount equal to or greater than its
reportable quantity (RQ) obligates the releaser to notify the National
Response Center (NRC) by telephone in a timely fashion. The purpose of
assigning RQs to hazardous substances is to allow the NRC to decide whether an
immediate government response is warranted and necessary to prevent escalation
of and to mitigate the problem resulting from the release of hazardous
substances.
In principle, the RQ should be high enough to eliminate unnecessary telephone
calls to the NRC, but low enough to trigger early response to a release that
may otherwise pose a threat to the public health or welfare or to the
environment. The Agency has used this principle as the basis for its RQ
adjustments.
This report describes the selected strategy for adjusting the RQs of the
hazardous substances defined in CERdA Sectin 101(14). Alternative strategies
considered by the Agency are also discussed. In the development of the
selected strategy, many alternatives were explored, and comments on these
alternatives were solicited from industry, environmental groups, and from
personnel within other federal agencies. Whenever possible, the suggestions
of the ccrttnenters have been incorporated into this final draft.
STATUTORY HISTORY
The major purpose of this document is to provide the U.S. Environmental
Protection Agency (EPA) with the technical background required to adjust the
RQs of hazardous substances designated in Public Law 96-510, the
"Conprehensive Environmental Response, Compensation, and Liability Act of
1-1
-------
1980" (more ccnmonly known as CERCLA or Superfund). Section 101(14) defines
hazardous substances as:
A. Any substance designated pursuant to Section 311(b)(2)(A) of the
Federal Water Pollution Control Act,
B. Any element, compound, mixture, solution, or substance designated
pursuant to Section 102 of this Act,
C. Any hazardous waste having the characteristicis identified under or
listed pursuant to Section 3001 of the Solid Waste Disposal Act (but
not including any waste the regulation of which under the Solid Waste
Disposal Act has been suspended by Act of Congress),
D. Any toxic pollutant listed under Section 307(a) of the Federal Water
Pollution Control Act,
E. Any hazardous air pollutant listed under Section 112 of the Clean Air
Act, and
F. Any imninently hazardous chemical substance or mixture with respect
to which the Administrator has taken action pursuant to Section 7 of
the Ttoxic Substances Control Act.
It should be noted that the term "hazardous substance" does not include
petroleum, including crude oil or any fraction thereof which is not otherwise
specifically listed or designated as a hazardous substance. The term does not
include natural gas, natural gas liquids, liquefied natural gas, or synthetic
gas usable for fuel (or mixtures of natural gas and such synthetic gas).
Final regulations listing hazardous substances have been promulgated pursuant
to the Clean Water Act, the Clean Air Act, and FCPA. The 297 chemicals
designated as hazardous substances pursuant to Section 311 of the Clean Water
1-2
-------
Act (CWA), and listed in 40 CFR Part 116 are hazardous substances for purposes
of Superfund. The implementing regulations on designation appear in 40 CFR
Part 116 and the RQs in 40 CFR Part 117. The RQs promulgated under CWA
Section 311 are all essentially based on aquatic toxicity. The 297 hazardous
substances are classified into five categories depending on their aquatic
toxicity. The categories are designated X, A, B, C, and D, with corresponding
RQs of 1, 10, 100, 1000, and 5000 Ibs, respectively. It should be emphasized
that the primary scientific basis for the RQ assigned is the aquatic toxicity
of the substance, as measured in screening tests using fresh water or marine
species. (Aquatic toxicity is discussed in detail in Section 5.)
The 65 substances and groups of compounds that have been listed pursuant to
CWA Section 307(a) are hazardous- substances. This list could include
thousands of pollutants if all compounds in each class and all organometallic
compounds v\ere considered. To implement CWA Section 307(a), the Agency chose
129 individual compounds as priority pollutants (three of these have since
been removed from the list). Under CERCLA, RQs have been adjusted as
indicated in this report only for the 126 specific priority pollutants,
because some of the broad classes encompass hundreds of specific ccmpounds.
Therefore, it vould be virtually impossible for the Agency to devlop an RQ for
a generic class of compounds that would take into account the characteristics
of all the specific compounds.
The seven hazardous air pollutants that have been identified pursuant to the
Clean Air Act (CAA), Section 112, are also hazardous substances for Superfund
purposes. National emission standards have been promulgated for four
hazardous air pollutants—asbestos, beryllium, mercury, and vinyl chloride—in
40 CFR Part 61. Benzene, radionuclides, and inorganic arsenic have been
listed as hazardous air pollutants, but no national emission standards have
yet been promulgated.
1-3
-------
All of the hazardous wastes that have been identified in 40 CFR Part 261
pursuant to Section 3001 of the Solid Waste Disposal Act (more cotttnonly
referred to as RCRA) are also hazardous substances. 40 CFR Part 261
identifies several types of hazardous wastes, contains a number of lists of
different classes of hazardous wastes. Some of the lists are specific; some
are not. The P- list consists of 107 acute hazardous wastes; the U- list
contains 233 commercial chemical products or manufacturing chemical
intermediates that are identified as toxic wastes unless otherwise designated.
The F- list contains 13 hazardous wastes from nonspecific sources. F001, for
example, is described as the following spent halogenated solvents used in
degreasing: tetrachloroethylene, trichloroethylene, methylene chloride,
1,1,1-trichlorethane, carbon tetrachloride, and chlorinated fluorocarbons;
and sludges from the recovery of these solvents in degreasing operations. The
K- list consists of 76 hazardous wastes from specific sources. 40 CFR Section
261.20 to 261.24 identify materials that exhibit the characteristic of EP
(extraction procedure) toxicity, ignitability (I), corrosivity (C), and
reactivity (R), but does not identify particular conpounds.
To date, no action has produced a list of hazardous substances pursuant to
Section 7 of the Toxic Substances Control Act.
Section 102 of the Act states:
(a) The Administrator shall promulgate and revise as may be
appropriate, regulations designating as hazardous substances, in
addition to those referred to in Section 101(14) of this title, 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, and shall promulgate
regulations establishing that quantity of any hazardous substance the
release of which shall be reported pursuant to Section 103 of this
title. The Administrator may determine that one single quantity shall
be the reportable quantity for any hazardous substance regardless of
the medium into which the hazardous substance is released.
1-4
-------
(b) Unless and until superseded by regulations establishing a
reportable quantity under subsection (a) of this section for any
hazardous substance as defined in Section 101(14) of this title, (1) a
quantity of one pound, or (2) for those hazardous substances for which
reportable quantities have been established pursuant to Section
311(b)(4) of the Federal Water Pollution Control Act, such reportable
quantity, shall be deemed that quantity, the release of which requires
notification pursuant to Section 103(a) or (b) of this title.
Under CERdA the list of 297 chemicals designated as hazardous substances
pursuant to the CWA. Section 311 (b) (2) (A) are assigned RQs pursuant to the CWA
Section 311 (b) (4). For all other substances the statute requires that the RQs
shall be 1 Ib.
ORGANIZATION OF REPORT
Section 2 contains a discussion of the scientific and technical strategies for
adjusting the RQs and a description of some strategies that may be implemented
later. It includes a discussion of the use of the primary criteria
(ignitability, reactivity, aquatic toxicity, mammalian toxicity, chronic
toxicity, and carcinogenicity) and the secondary criteria (biodegradability,
hydrolysis, and photolysis). It also includes a table of the 607 chemically
separate and distinct designated hazardous substances, with synonyms and
proposed RQs. Section 3 contains a description of an alternative method for
adjusting RQs, the Hazard Index approach. Administrative considerations are
discussed in Section 4. Sections 5 and 6 provide technical discussions on
aquatic toxicity and mammalian toxicity, respectively. Section 7 describes the
data management system employed in determining the basis for proposing RQs for
the hazardous substances. Section 8 contains the data tables for the chemicals
supporting the proposed RQs displayed in Section 2. Section 9 contains similar
data tables for the RCRA hazardous wastes.

SUMMARY OF RQ AEOUSTMEOTS
RQs for many of the substances have been adjusted. Ihe technical basis for
those RQ adjustments is included in this report. For some of the hazardous
substances with RQs pursuant to the CWA, it has been found necessary to
recommend that the RQ be adjusted downward. Ihe primary reason for this is that
the RQs established pursuant to Section 311 of the CWA were assigned based on
the aquatic toxicity exhibited by the hazardous substance. Since Superfund
evaluates additional criteria, the RQ may be lower for some substances. Most of
the RQs for hazardous substances have been raised frcm the 1-lb level. The net
effect of the use of Selected Criteria Processing for adjusting the RQ is to
decrease the number of hazardous substances with 1-lb RQs from 334 to 46, as
indicated below.
tfc>. of Substances with Specified RQs
RQ (Ibs) Statutory RQ Proposed RQ
1 334 46
10 27 40
100 41 89
1000 111 95
5000 94 91
CARC TEA 86
CHRON TEA 91
CARC CHRON TEA 69
The last three items are hazardous substances for which RQs are still to be
determined because the data for many of these substances are being evaluated.
The CARC TEA refers to carcinogens to be assessed by the EPA's Carcinogen
Assessment Group (GAG), the CHKQN TBAs are the chronically toxic substances to
be assessed by the Environmental Criteria Assessment Office (ECAO). The
CARC/CHRON TEA are the substances to be assessed for both chronic toxicity and
carcinogenicity.

STRATEGY FOR RQ ADJUSTMENT AND ASSIGNMENTS
TO THE CERCIA 101(14) LIST
Table 2-1 lists all of the CERCLA hazardous substances, together with the
statutory RQ and any proposed RQ (if one is available) for each hazardous
substance. The list is arranged alphabetically and identifies by numerical
code in the Statutory Code column the statutory source for designation under
CERCIA Section 101(14). (The hazardous substances designated under CWA
Sections 311 (b) (4) and 307(a), the hazardous air pollutants designated under
CAA Section 112, and the hazardous-wastes listed under RCRA Section 3001).
The codes are explained in the footnotes to the table. In addition, since
many chemicals are regulated by more than one statute and may be identified
under different names in the different statutes, all possible names have been
listed and the synonyms included in the Regulatory Synonyms column. Each
hazardous substance is uniquely identified by its Chemical Abstracts Service
(CAS) registry number.
Additional CAS registry numbers are included for the CWA Section 311
designated hazardous substance families, hydrates, esters (e.g., 2,4,5-T
esters) and solutions. For those substances designated under RCRA Section
3001 the appropriate P and U waste numbers are listed in the RCRA Waste Number
column. The generic groups of chemicals designated under CWA Section 307(a)
such as "SILVER AND COMPOUNDS' are printed in all-capital letters and have
only the statutory 1-lb RQ assigned to them.
CERCIA statutory 1-lb RQs are distinguished from CWA Section 311 1-lb RQs by
the symbol 1*. Potential carcinogens for which no RQs are being proposed at
this time are identified in the Proposed RQ column by the symbol #. Hazardous
substances that remain to be assessed for chronic toxicity are identified in
the same column by the symbols ##. Those hazardous substances that remain to

The list also includes the 89 hazardous waste streams designated under 40 CFR
Parts 261.31 and 261.32 (RCRA. F and K lists). These waste streams contain
some CERCIA hazardous substances, and the RQs for these waste streams are
based on those hazardous constituents. Many of the waste streams in 40 CFR
Parts 261.31 and 261.32 have more than one hazardous constituent. One RQ,
which represents the lowest RQ of the hazardous constituents present in the
waste stream, is assigned to that waste stream.
For wastes F001 through F005, individual RQs are proposed for each solvent.
The wastes F001 through F005 are treated differently because each of these
wastes is a collective listing of different individual solvents. A listed
waste will be one, but only one of these solvents. RQs are given for each of
these solvents. If the releaser knows the solvent involved, he may rely on
the RQ given for that solvent. If a releaser does not "know what solvent is
involved, he must use the RQ for the waste itself, which is set at the lowest
RQ of the solvents listed for that waste.
The original regulatory listings have been compiled into the CEFCLA 101(14)
list in the following manner:
1. CWA Section 311 - 297 chemicals which are listed in 40 CFR Part 117
and which have RQs assigned based on aquatic toxicity. In many
cases, the substances listed in 40 CFR Part 117 refer to isomers and
multiple oanpounds of the substances. For instance, if one refers
back to the designation rule (40 CFR Part 116, Table 116.4A), one
finds not only the entry "Cresol" (CAS No. 1319733), but also the
listing of cresol's isomers, i.e., the ortho-, meta-, and
para-isomers (CAS Nbs. 95487, 108394, and 106445, respectively).
Similarly, under the entity "2,4-D Esters," while no specific names
are given, CAS numbers for 1C) different compounds are listed. Where
2-60
-------
isomers and multiplicities of compounds exist for CWA substances,
they "have been shown and all the individual CAS numbers listed as a
part of the entry. See Table 2-1.
2. CWA Section 307(a) - 65 classes of chemicals and 126 specific
chemicals (priority pollutants). The 126 pollutants were derived
frcm the original 65 broad generic classes, such as "Chlorinated
benzenes," "chlorinated phenols," "haloethers," "halanethanes," and
"polychlorinated biphenyls." The 126 specific canpounds were arrived
at after a. series of negotiations between the Agency and the
plaintiffs in the case that resulted in what is connonly known as the
"Consent Decree."
j
3. CAA Section 112 - Seven chemicals. 40 CFR Part 61 lists National
Enission Standards for four hazardous air pollutants.
4. TSCA - no entries.
5. RCRA Section 3001 - 40 CFR Part 261 lists the following:
A. Specific chemical wastes -
"U" List - 233 chemicals
"P" List - 107 chemicals
B. Waste streams -
"F" List - 13 wastes
"K" List - 76 wastes
Since many substances are listed under more than one environmental statute,
there are some duplicate entries. After these duplicate entries are
discounted, the CERCXA 101(14) list comprises a total of 607 substances. Of
these 607 substances, the 297 materials designated as hazardous substances
2-61
-------
pursuant to Section 311 of the Clean Water Act have previously been assigned
RQs of 1, 10, 100, 1000, or 5000 Ibs, based on their level of acute toxicity
to aquatic organisms. For the remaining 310 substances, CEFdA assigns an RQ
of 1 lt» (CERCIA Section 102 (b)). These statutory RQs were intended to be of
temporary duration, pending EPA review and adjustment of these RQs. The
purpose of this rulemaking is to adjust the statutory RQs based upon specific
technical criteria. The adjustments allow the Agency to focus its resources
on those releases that are most likely to pose threats to public health and
welfare and the environment, and will relieve the regulated ccmnunity from the
burden of reporting releases that are unlikely to pose such threats. The
strategy presented herein provides a simple, understandable, and implementable
framework to assign RQs.
STRATEGY FOR RQ ADJUSTMENT
The selected strategy for RQ adjustment consists of evaluating the intrinsic
properties of the hazardous substances designated by definition in CERCIA
Section 101(14), and associating these properties with a five-tier ranking
scale to arrive at a single adjusted RQ for each substance. The intrinsic
properties are ignitability, reactivity, aquatic toxicity, mammalian toxicity
(oral, dermal, inhalation), carcinogenicity, and chronic toxicity. For each
of these properties (except carcinogenicity, for which a ranking scale is
still under development), a ranking scale was set up to permit a substance to
be placed at one of five levels where appropriate to indicate the intensity of
the property. The Agency associated a specified range of values of each
property with a particular RQ value; those substances exhibiting the least
severe value of any property being assigned the highest RQ.
Nothing in the properties themselves requires that each of the properties be
grouped into five ranges of values or constrains the possible RQs to a
specific number of tiers. The association between RQ values and the intrinsic
characteristics was derived from the Clean Water Act reportable quantity
methodology. The Agency decided it was both feasible and practical to utilize
2-62
-------
this CWA methodology.
The final proposed adjusted RQ for a particular substance is the lowest RQ
assigned for any of the intrinsic properties. The overall strategy in
adjusting the RQs consists of associating the intrinsic physical, chemical,
and toxicological properties (i.e., the primary criteria) of the hazardous
substances with administratively selected RQ levels to arrive at a primary
criteria PQ. Finally, extrinsic dissipative properties (secondary criteria,
i.e., biodegradation, hydrolysis, and photolysis) are applied to make final PQ
adjustments when appropriate.
The decision has also been made to have a single RQ for each hazardous
I
substance and "this single quantity requires notification upon release into
any environmental medium" in accordance with the legislative mandate.
Although it is recognized that some substances may pose different hazards when
released into different media, for example hydrogen sulfide released into
water is an aquatic or oral mamnalian toxicity hazard, whereas when released
into air it is primarily an inhalation toxicity or ignitability hazard, the
legislative history permits, and indeed encourages, the assignment of a single
RQ without "linking such quantity to any subjective concept of harm" (see
quote on p. 4-1).
The Agency has determined that it is more administratively feasible to have a
single quantity for each substance, in order to develop a simple and practical
notification system. If multiple RQs that vary in accordance with the
environmental media into which the substance is released were established, it
would be more difficult for the regulated community to comply with the
reporting requirements. Since releases often occur into more than one medium,
under a multi-RQ format the releaser would be uncertain as to which RQ would
apply. Consequently, the single RQ system is considered the better approach
for use by the Agency. This decision also accords with the wording in CERCIA
Section 102(a): "The Administrator may determine that one single quantity
shall be the reportable quantity for any hazardous substance, regardless of
2-63
-------
the medium into which the hazardous substance is released."
Selected Criteria Processing
The strategy for adjusting the statutory KQs is known as Selected Criteria
Processing (SCP). A chart sunmarizing the strategy used in arriving at the
suggested PQs is shown in Figure 2-1. As noted above, the strategy employed
in arriving at the RQ adjustments and assignments suggested in this report for
the CERCIA 101(14) list is based on a rating system using six primary
criteria: aquatic toxicity, mammalian toxicity, chronic toxicity,
ignitability, carcinogenicity, and reactivity. Each material is evaluated
pursuant to these primary criteria. The five-level RQ rating system derived
for aquatic toxicity under CWA Section 311 is used as a baseline for this
analysis. This RQ rating system consists of the following five RQ categories,
linked to the specified aquatic toxicity ratings:
Category RQ (Ibs)
X 1
A 10
B 100
C 1000
D 5000
Five-level RQ rating scales were developed for mammalian toxicity, chronic
toxicity, ignitability, and reactivity. The methodology for selecting these
rating scales will be discussed later in this section. The rating system for
mammalian toxicity includes separate scales for oral, dermal, and inhalation
toxicities.
For each hazardous substance on the CERCIA 101(14) list, available data for
each of the appropriate criteria were tabulated and an RQ was associated with
the various data by letter code (i.e., Category X [1 Ib}, A [10 Ibs], B [100

Ibs], C [1000 Ibs], or D [5000 Ibs]). Sane substances may not, due to their
inherent characteristics, exhibit all the primary criteria. For instance,
some substances are not ignitable or reactive. Accordingly, these
characteristics are not evaluated.
The primary criteria RQ is the lowest RQ derived from all the characteristics
of a compound. For example, the following RQ values were determined for the
primary criteria for the compound ammonium sulfide (see Table 8-1, page 8-4).
Aquatic Tbxicity D (5000 Ibs)
Mammalian Tbxicity B (100 Ibs)
Chronic Tbxicity No rating
Carcinogenicity No rating
Ignitability C (1000 Ibs)
Reactivity B (100 Ibs)
In this case, the final RQ assigned to ammonium sulfide is 100 Ibs, based on
the lowest values determined for the individual criterion. A more detailed
description of the steps that were followed in the RQ adjustment strategy for
all compounds is given below. (Refer also to Figure 2-1.)
1. The aquatic toxicity, mammalian toxicity, ignitability, and
reactivity data for each material (where appropriate) were evaluated
and the data for that criterion which resulted in the lowest RQ
assignment were used as the basis for the suggested RQ. These data
are tabulated in Tables 8-1, 9-1, and 9-2.
2. The Environmental Criteria and Assessment Office (ECAD),
EPA-Cincinnati, has developed a five-tier chronic toxicity ranking
procedure that incorporated a combination of minimum effective dose
and severity of effect. The ECAO has currently assessed only 64
substances for chronic toxicity and is still evaluating chronic
2-66
-------
toxicity data for another 160 substances. (See Tables 8-1 and 9-1.)
The latter substances are marked "TEA" (to be assessed) in the
tables.
3. If a material was identified as a carcinogen, it was labeled "TEA"
pending development and application of an appropriate ranking method
by the Agency's Carcinogen Assessment Group (GAG). CAG's work to
date on carcinogen ranking methods, which will probably form the
basis for RQ adjustments, can be found in Appendix A.
PQ Scale for Aquatic Toxicity
The RQ scale used in the SCP process described here was originally developed
by the Agency in promulgating regulations under CWA Section 311. It relates
aquatic toxicity to reportable quantities in a five-tier system, as shown

In Tables 8-1 and 9-1, the RQ previously established an the basis of aquatic
toxicity in 40 CFR Part 117 under CWA. Section 311 is identified in either a
column headed "311 RQ," or as the basis for suggesting an RQ, shown as "311."
Of the 297 hazardous substances listed under CWA. Section 311, the RQs for 28
were lowered; however, assessment of all 297 substances is not yet complete
for chronic toxicity and carcinogenicity and therefore the RQs will most
likely be lowered for several other CWA Section 311 substances. Such lowering
is justified by the fact that characteristics such as mamnalian toxicity,
chronic toxicity, ignitability, corrosivity, and reactivity must be considered
for the purposes of CERdA (i.e., multimedia releases) and these factors were
not considered in arriving at the CWA 311 RQs, which were based on releases to
water only. In a few cases, CWA 311 RQs were also adjusted downward on the
basis of newer aquatic toxicity data. In the process of such downward
adjustments made for the CWA. 311 items, aquatic toxicity data appearing in the
Ambient Water Quality Criteria Documents were used. Since acute aquatic
toxicity is one of the primary ranking factors in this scheme, it became the
basis on which the RQ was determined if it resulted in the lowest value from
all assessed criteria. This has the effect of maintaining the 311 RQs in the
majority of cases. No newer acute aquatic toxicity was revealed that resulted
in assigning an RQ higher than that originally assigned under CWA Section 311.
A more detailed analysis of the status of the CWA 311 substances is given
below.
Aquatic toxicity data from the Oil and Hazardous Materials Technical
Assistance Data System (OHMIADS) was accessed via CIS (the Chemical
Information System - see Section 7) and was supplemented with values in the
Ambient Water Quality Criteria Documents prepared by the Criteria and
Standards Division of the EPA Office of Water Regulations and Standards.
As a special case, all cyanide compounds (including the generic class) were
assigned a suggested RQ of 10 Ibs based on the aquatic toxicity of cyanide as
developed under Section 311 of the Clean Water Act. None of the other
2-68
-------
criteria, including the inhalation toxicity of hydrogen cyanide, justify a
lower RQ to be suggested for other cyanide compounds.
Status of Substances Designated Under CWA Section 311—
Several substances (22) originally designated under CWA Section 311 were found
to have aquatic toxicity data which, if used as a single criterion in the RQ
adjustment process, would place those substances into lower reportable
quantity categories than those previously assigned under CWA Section 311.
This newer aquatic toxicity data is tabulated in Tables 8-1 and 9-1 and was
used for adjustment of RQs accordingly. However, since aquatic toxicity is
only one of several criteria used in the RQ adjustment process for the
purposes of CERCIA, not all of the substances involved "had their RQs lowered
on the basis of this newer aquatic toxicity data. The net effect is as
follows. Ten of the 22 substances have been placed in the "to be assessed"
category for either carcinogenicity and/or chronic toxicity, hence no RQ has
been proposed for these substances at this time. The RQs for seven of the
substances were lowered exclusively on the basis of the newer aquatic toxicity
data, and the RQs for four of the substances were lowered on the basis of the
newer aquatic toxicity data in combination with one or more of the remaining
adjustment criteria. The remaining substance, acetyl chloride, was initially
lowered using the newly available data, but was readjusted upward using the
secondary criteria for natural dissipation. The 22 substances are identified
in Table 2-2, along with their CWA Section 311 RQs, their CERCIA proposed RQs,
and the basis for the proposed RQs.
RQ Scales for Mammalian Toxicity
The rating system for mammalian toxicity is shown in Table 2-3. It includes
separate scales for oral, dermal, and inhalation toxicities. The toxicity
ranges shown are either in U550 values (oral and dermal toxicity) or in I£CQ
values (inhalation toxicity). The term IT>50 means that lethal dose (LD),
expressed as milligrams per kilogram (mg/kg) of body weight of the test animal
that will kill 50% of the test animal population. Similarly, the term I£

-------
means the lethal concentration (LC) in air, expressed in parts per million
(ppm) that will ld.ll 50% of the test animal population. More details on the
nature of mammalian toxicity studies are given in Section 6.
In developing the five-tier scales, the first step was to choose an upper
limit. That limit was then correlated with an RQ category of D (5000 Ibs).
The ranges corresponding to categories X, A, B, and C (1, 10, 100, and 1000
Ibs) were then selected based on ratios of the upper limit to each lower
category range in the same ratios as had been established in prior regulations
for the aquatic toxicity scale (see p.2-62 above).
The upper limits for dermal and inhalation toxicity were based on the
toxicological selection process used in the screening and evaluation of
elements and compounds for designation as hazardous substances in 40 CFR Part
116. The same upper limits have been used in five-tier scales developed by
the National Academy of Sciences in their "System for Evaluation of Hazards of
Bulk Water Transportation of Industrial Chemicals" (USCG-D-113-74, report to
the Department of Transportation, U.S. Coast Guard, February 1974).
The upper limit for oral toxicity was set at 500 mg/kg based on the following
considerations. The "standard man" might be exposed to situations that would
allow him to inadvertently take one swallow of a hazardous substance. For a
substance of unit density, a body weight of 70 kg, and a swallow volume of 21
cubic centimeters, this is equivalent to taking a dose of 300 mg/kg. Allowing
for variations in swallow volume, and for material of greater than unit
density leads to the selection of 500 mg/kg as the upper limit. Thus, if the
standard man takes one swallow of a material whose I£cn is below 500 mg/kg,
there is a 50% probability he will die. (It should be noted that these same
calculations applied to a small child of 15 kg body weight, 4 to 4.5 cubic
centimeters swallow volume, will also result in an upper limit of 500 mg/kg.
The set of assumptions was reviewed by one of the nation's foremost
authorities on problems of poisoning of children, Dr. Howard Mossensen at the
Nassau County Medical Center on long Island, New York. Dr. Mossensen agreed
2-72
-------
that the assumptions ware reasonable and would provide a high degree of
protection in the event of such an exposure.
In assessing substances under this criterion, LD5O values from animal studies
were used; statistically valid human ID values are available in only
isolated cases, since human populations are not generally subjected to
deliberate toxicity studies. Data on human toxicity is generally reported as
LDLo values. The term IDLo means "low lethal dose," and refers to the lowest
dose on record believed to have caused a fatality. Human IDLo data are not
especially reliable, since they derive fron individual incidents of accidental
human poisoning, and generally rely on information reported by the victim,
regardless of the validity of such a report. For example, the LD50 (oral,
rat) of sodium chloride (common table salt) is 3000 mg/kg, but the recorded
human LDLo is only 500 mg/kg. The Agency clearly does not consider such a
catmonly used item as sodium chloride a hazardous substance.
When data for more than one mammalian toxicity route were available, the value
chosen for the mammalian toxicity criterion represents the lowest of the
values derived frcm the three scales. For example, if inhalation toxicity
yields an RQ of 1 Ib, while oral and dermal exposures yield values of 10 Ibs,
then the RQ based on mammalian toxicity would be 1 Ib.
Available mammalian toxicity data came frcm the NIOSH Registry of Toxic
Effects of Chemical Substances (RTECS) via the Chemical Information System
(CIS). RTECS is updated quarterly, and currently contains toxicity
information for almost 50,000 ccmpounds.
Nbnequivalence of Toxicity Scales—
Although the three mammalian toxicity scales and the aquatic toxicity scale
are each equated to the same RQ categories and poundage levels, the scales are
not equivalent to each other. Each scale represents an independent entity;
there is no implication that potential danger to human health, welfare, and
the environment are equivalent when substances have the same ranking on
2-73
-------
different scales. A 1000-Ib RQ assigned, for example, to acetic acid on the
basis of aquatic toxicity does not mean that it is equivalent in danger or
hazard to lead arsenate, assigned a 1000-lb RQ on the basis of oral toxicity.
Identification of Carcinogens
Carcinogens will be evaluated for possible RQ values following the development
of an appropriate evaluation and ranking scheme. The Carcinogen Assessment
Group (CAG) is presently developing an RQ adjustment methodology for
carcinogens. This methodology will probably utilize a carcinogen hazard
ranking based on a substance's potency as a carcinogen and lARC's (the
International Agency for Research on Cancer) classification of strength of
evidence of carcinogenicity. The procedure outlined in Appendix A will
probably form the basis for this methodology. Potential carcinogens were
identified from lists published by the following sources:
1. U.S. Department of Health and Human Services, National Toxicology
Program, U.S. Public Health Services
A. First Annual Report on Carcinogens, July 1980 - lists 26
substances or classes of substances.
B. Second Annual Report on Carcinogens, December 1981 - lists 88
substances or classes of substances
2. International Agency for Research on Cancer, Summary of Monographs
1-2, September 1979 - lists 142 substances
The bases for selecting these materials as potential carcinogens are the IARC
"sufficient evidence" criteria: the evidence must indicate a causal
association between exposure and human cancer, or if based on animal studies,
must show an increased incidence of malignant tumours (a) in multiple species
or strains, or (b) in multiple experiments, or (c) show an unusual degree of
2-74
-------
incidence, site or type of tumour, or age at onset.
Carcinogens listed in Table 2-1 are not assigned an RQ. They are listed with
a symbol showing that they are still to be assessed on the basis of
carcinogenicity. However, in the working tables (8-1, 9-1, and 9-2), while
they are identified as carcinogens, a suggested RQ is based on whatever other
SCP data is available. This is because the carcinogenicity ranking scale
cannot be predetermined, and it is possible that some substances may prove to
have lower RQs based on other criteria, despite the fact that they are
carcinogenic.
The listings given above lead to the identification of 86 substances in Table
2-1 as potential carcinogens.
RQ Scales for Chronic Toxicity
Tables 8-1 and 9-1 present RQ rankings for 23 chemical substances based on
chronic toxicity. For purposes of this report, chronic toxicity is defined as
toxicity due to repeated or continuous exposure from a single or multiple dose
of a designated substance. These substances were evaluated and had RQs
assigned by the ECAO, EPA Cincinnati. The ranking based on chronic toxicity
reflects two primary attributes of each chemical:
The minimum effective dose (MED) levels for chronic exposures (ing/day
for 70-kg man) via alternative environmental media (air, water, etc.)
Type of effect (liver necrosis, teratogenicity, etc.)
The dose rating for a given chemical is based upon the minimum effective dose
transformed to values ranging from 1 to 10 using the graph given in Figure
2-2. Substances having an effect at a low dose (i.e., those that are more
highly toxic) will be given a high rating on this graph, while those requiring
a high dose (less toxic) will be given a low rating. The rating values range

-------
frcm 1 to 10. Similarly, the effect rating for an individual chemical will
range frcm 1 to 10 depending on severity (Table 2-4), with 10 being the most
severe. These values must be assigned on a chemical-by-chemical basis. A
final composite score is determined by multiplying the dose rating by the
effect rating. The possible range of composite scores is thus 1 to 100.
These values are correlated with the scheme for RQs as follows:
Composite Score RQ (Ibs)
81-100 1
41-80 10
21-40 , 100
6-20 j 1000
1-5 5000
Using this scheme, only those compounds eliciting what are judged to be the
most severe effects at low levels of exposure would fall in the RQ category of
1 Ib. Table 2-5 shows the detailed results of applying the above procedures
to 23 of the chemical substances. In all, 64 substances have been assessed
for chronic toxicity, while 160 are still in progress. Data on all such
materials are given in Tables 8-1, 9-1, and 9-2. Those that are still in
progress are identified as "TEA" (to be assessed).
RQ Scales for Ignitability and Reactivity Evaluations
The starting point for the rating scales for PQ selection based on the
parameters of ignitability and reactivity have their origin in vrork done by
the U.S. National Academy of Sciences for the U.S. Coast Guard in 1974
(USCG-D-113-74, System for Evaluation of the Hazards of Bulk Water
Transportation of Industrial Chemicals; a Report to the Department of
Transportation, U.S. Coast Guard. National Academy of Science - National
Research Council, Washington, DC, February 1974). This USCG report describes
the development of a five-level system to evaluate these factors, as shown in

Table 2-6. As discussed below, these scales were modified by the Agency.
Exclusion of the X (1-lb) RQ Level—
Small releases (i.e., 1 Ib) of flammable, reactive, or explosive materials are
handled by the spiller, or by state and/or local responders: fire, police,
bomb squads, and so on. The EPA will not usually respond to such incidents,
and does not intend to regulate such releases. Furthermore, small releases
(less than 10 Ibs) of ignitable or reactive substances, once ignition or
reaction has been initiated, would be consumed so quickly that any federal
government response action would be infeasible. Accordingly, it was decided
to abandon the RQ Category X level for the ignitability and reactivity scales
and set the lowest possible ratings based on these factors equivalent to RQ
Category A (10 Ibs).
Ignitability Scale Adjustment—
The NAS scale (Table 2-6) ignores a very important aspect of ignitability, and
one that may be considered even more hazardous than simply having a very low
flash point; that is, the characteristic of being able to start a fire on its
own. Three types of compounds have this characteristic, and are classed as
follows:
Pyrophorics: Those compounds that immediately ignite because of rapid
oxidation as soon as they contact oxygen
Spontaneously Ignitable: Those compounds that may not immediately
ignite, but that can do so if spread in a thin layer, or brought into
contact with iron oxide or other catalysts
Strong Qxidizer: Those compounds that can cause fuel materials to
ignite, and support their combustion once they are ignited

-------
Accordingly, it was decided to make this category—the ability to start
fires—the most hazardous, and to move the other ignitability factors up one
level on the table. As a result, the "nonconibustible" category was discarded.
Discarding this category ("FP >140°F," flash point greater than 140°F) does
not present any problem. In fact, with this discarded, the upper limit of the
scale (14CTT?1) corresponds with the upper limit used to assess the
characteristic of ignitability in the regulations issued under FCRA, 40 CFR
Part 261.21.
The three upper numerical categories correspond to National Fire Protection
Association (NFPA) classes. (NFPA No. 30, Flammable and Combustible Liquids
Code, National Fire Protection Association, 470 Atlantic Avenue, Boston,
Massachusetts. This document Is updated periodically. The most recent
edition was published in 1980. However, the flammability and combustibility
classes have not changed in recent editions.) The correspondence is as

Water Reactivity Scale Adjustment—
The NAS water reactivity scale ignores a very important aspect of this
characteristic, namely the case of materials that react with water in such a
fashion that inflammation of evolved gases occurs. Accordingly, it was
decided to reserve the lowest of the four levels (corresponding to RQ Category
A, 10 Ibs) for such compounds. This includes such substances as sodium, the
other alkali metals, calcium carbide, and a number of others that are
identified by the U.S. Department of Transportation as Flamnable Solids
(Dangerous When Wet). Both Reactivity scales, as well as the Ignitability
2-84
-------
scale, are shown in Table 2-7, along with the assigned RQ categories. As in
the case of Ignitability, the lowest level has been abandoned for Reactivity.
Note that with this change, the two reactivity scales and the ignitability
scale become much more self-consistent, in that the lowest category in all
three is reserved for substances that lead either to fires or explosions under
various conditions of release.
The reactivity rankings take into account all but one of the factors used to
assess the characteristic of reactivity (i.e., reactive with water, capable of
detonation, normally unstable, explosive decomposition) in the regulations
issued under RCRA, 40 CFR Part 261.23. The RCRA factor not covered is that
certain wastes mixed with water or acid can generate toxic gases. Che case is
!
that of the cyanides, which can'be ranked appropriately on the basis of CWA
Section 311 ranking for cyanides. Others, such as those that could generate
phosphine (PELJ or hydrogen sulfide (HpS) have been treated as special cases
of reactivity, and have been addressed as such with individual discussion when
ranked.
RQs Based on Structural Similarity
Data were available to assign PQs on the basis of the primary criteria for
most of the CERdA hazardous substances. Ifcwever, six substances that had
little available data on the primary criteria were assigned PQs based on the
proposed RQs for hazardous substances similar in structure and substituents.
The substances are:
1. Methane, dibromo- (methylene bromide)
2. Nitrophenols
3. Dinitrophenol

4. Hexachlorocyclohexane (all iscmers)
5. Dichloropropane
6. 4-Chlorophenyl phenyl ether
In these six cases the relationship to other compounds is so close that this
assignment process is considered completely valid. Thus, data from both
mcmobromo- and tribrananethane are available (Table 9-1) to indicate the RQ to
assign to the dibrcmo- compound. Nitrophenols, dinitrophenol,
hexachlorocyclohexane, and dichloropropane are assigned RQs on the basis of
their specific iscmers that have available data (e.g., dichloropropane is
assigned the same RQ as determined for the specific isomer
1,2-Dichloropropane). Finally, 4-chloro-phenyl phenyl ether is assigned an RQ
based on the oral mammalian toxicities of bis (chlorophenyl) ether and diphenyl
ether. In both these latter cases, the mammalian toxicity would result in
assigning RQ Category D (5000 Ibs).
Summary of the Merits of the SCP Strategy
The Selected Criteria Processing strategy outlined above for RQ adjustments to
the CERdA Section 101(14) list is considered appropriate for the following
reasons:
1. For each substance, it focuses on the dangerous property of greatest
concern;
2. It provides the necessary link between human health and an RQ;
3. Much of the data required for its application are available;
4. It can provide for further adjustments based on comments, new data,
and considerations of administrative feasibility;
2-87
-------
5. It uses established strategies for arriving at an RQ (i.e., Section
311 of the Clean Water Act) ;
6. It permits emphasis on the appropriate medium (air, water, soil);
7. It permits maximum flexibility;
8. It minimizes arbitrariness.
Secondary Criteria for Mjusting RQs
The RQs derived using the Selected Criteria Processing (SCP) strategy and its
various scientific/technical criteria represent an approach based on the
potential effects of hazardous substances on human health, welfare, and the
environment. The adjustment of RQs would be incomplete, however, if
consideration were not given to evaluating at the same time the potential
effects that the environment can have on hazardous substances. There are
several chemical, biological, and physical processes that are important for
transforming or transporting chemicals in the environment. A few of these
processes (biodegradation, hydrolysis, and photolysis) can be considered
important in reducing the concentration of certain chemicals when released
into the environment and hence ultimately ameliorating the effects of
hazardous substance releases.
For those substances that are known to undergo one or more of these
transformation processes to less hazardous or innocuous products, less
attention would be necessary from a federal emergency response standpoint
(i.e., a larger PQ would be justified) and Agency resources could better be
focused on those releases of hazardous substances that pose a threat to the
public health, welfare, and the environment. At the same time, necessary
relief could be provided to the regulated community (i.e., a larger RQ) so
2-88
-------
that they are not overburdened with reporting releases of naturally
dissipating hazardous substances. For this reason, these secondary criteria
factors of biodegradation, hydrolysis, and photolysis have been
administratively considered as a basis for "fine-tuning" the RQs derived using
the SCP strategy where appropriate.
The processes that have been considered for upward adjustment of RQs are
limited to the transformation processes of biodegradation, hydrolysis, and
photolysis. The transport processes such as volatilization were not
considered to be suitable criteria for upward adjustments since these only
represent the transfer of a hazardous substance from one medium to another
(i.e., from water or soil to air), not its degradation or transformation to
less hazardous products. Sorption of hazardous substances to particulates was
also not considered to be a good criterion, since the process is reversible
and the suspended or benthic sediment to which hazardous substances may be
absorbed may later serve as a source of the chemical from sorption-desorption
equilibrium and the chemical in solution can be transferred to the air medium
by volatilization.
Many compounds, especially organics, can be biologically degraded over time,
either by natural or artificially induced means, and precedents for
biodegradation of hazardous substance spills exist. Biodegradation results
from the enzyme-catalyzed transformation of chemicals in aquatic and soil
environments by microbes that require carbon and energy for their growth and
maintenance. Hydrolysis of organic compounds usually results from the
reaction of the material with water to split a bond between chemical units,
introducing a hydroxyl group (-OH) into the chemical structure and forming a
small hydrogen-containing species (i.e., RX + H_O —> ROH + HX). Photolysis
of a chemical occurs if the chemical absorbs sunlight and then undergoes a
transformation reaction from an excited state by any one of several mechanisms
(i.e., dissociation, rearrangement, oxidation). Under all three processes,
the chemical is transformed into a less "hazardous substance.
2-89
-------
The upward RQ adjustment strategy is strictly an administrative one which
raises the RQ by one level for those substances on the CERdA 101(14) list
that are known to undergo biodegradation, hydrolysis, or photolysis and
degrade to less hazardous or relatively innocuous products.
Biological oxygen demand data (BOD) have been used for the primary evaluation
of a substance's biodegradability. If the BOD5 (5-day test at 20°C) value is
equal to or greater than 50% theoretical, a substance is considered to be
relatively biodegradable. (The theoretical oxygen demand is the
stoichiometric oxygen required to completely oxidize a substance to carbon
dioxide and water. The percent theoretical oxygen demand is the ratio of the
observed test results to the calculated demand.) If the reported BOD5 values
were less than 50% theoretical, and other BOD values (10-, 15-, and 20-day)
were greater than 50% theoretical, a substance was still considered to be
relatively biodegradable. The importance of the biodegradation process varies
according to such factors as concentration, pH, temperature, concentration of
microbes, availability of nutrients, and whether the microbes are acclimated
to the chemical of interest. .Additional evidence concerning the importance of
biodegradation, hydrolysis, and photolysis as processes for the 126 priority
pollutants designated under Section 307(a) of the CWA was drawn largely from
the evaluations documented in the "Water Related Ehvironmental Fate of 129
Priority Pollutants" (EPA-440/4-79-029a and b) as well as from data found in
the OHMTADS data base. Half-life data were taken into consideration if
listed. It should be noted here that for many of the hazardous substances
designated on the CERCLA 101(14) list, the predominant process or processes
and the importance of these processes cannot be identified at all or with any
reasonable degree of certainty because of a lack of data. Hydrolysis and
photolysis data which have been calculated or estimated using theoretical
methods are available for certain substances; however, these data have not
been confirmed and were not used in this application.
2-90
-------
The process of selecting candidates for upward adjustment involved the
following. An initial candidate list of 310 hazardous substances was derived
from the CERCEA 101(14) list using the following series of elimination
criteria:
1. Elimination of all substances with RQs already proposed at 5000 Ibs.
Under the five-tier notification system, 5000 Ibs is the largest RQ
that can be assigned for these substances.
2. Elimination of identified carcinogens. Adjustment of RQs on the
basis of carcinogenicity is under consideration by the Agency- Since
carcinogenesis is one of the most severe forms of chronic effect,
substances that exhibit carcinogenicity are not being considered for
upward adjustments.
Each hazardous substance on this initial candidate list was then assessed for
evidence of biodegradability, hydrolysis, and photolysis. At the same time
each substance was assessed to determine if it should be dropped from
consideration on the basis of any one or a combination of the following
factors:
A. Biodegradation not pertinent (i.e., substance is not a carbon source)
B. Evidence of bioaccumulation
C. Substance resists degradation or is persistent
D. Substance is highly inhibitory to microbes and not amenable to
biological treatment at municipal sewage treatment plants
E. Evidence of teratogenicity
2-91
-------
F. Substance presents unusual hazards (i.e., dangerously reactive,
poisonous gas)
G. Hazardous degradation or transformation products are generated
The data base for the review was as follows:
1. Water Related Environmental Fate of 129 Priority Pollutants
(EPA-440/4-79-029a and b)
2. "Handbook of Environmental Data on Organic Chemicals" (Karel
Verschueren, 1977)
3. Oil and Hazardous Materials Technical Assistance Data System
(OHMTADS)
Appendix B summarizes the results of this review for the 310 candidate
substances. It lists the BOD data that were available, identifies those
substances rejected on the basis of bioaccumulation, persistence, teratogenic
properties, reactivity, or hazardous degradation products, and indicates those
substances for which no data or insufficient information were available to
make an evaluation. Table 2-8 presents the final candidates (37 in number)
for which sufficient data are available to justify upward RQ adjustments (one
level) on the basis of either biodegradability, hydrolysis, or photolysis.
The majority of the candidates were selected because of biodegradability.
Also shown in the table are the original RQ assignments derived using the SCP
strategy and the basis on which those assignments were made. However, nine of
these final candidates have been simultaneously identified as being
chronically toxic or are currently being assessed for chronic toxicity. These
are identified in Table 2-8 with the entry CHRQN* or CHRON TEA in the
projected RQ column. For these nine substances, no upward adjustments are
recommended at this time. Upon completing an evaluation of the chronic
toxicity data, the Agency may still decide to raise the RQ levels for such of
these substances that transform rapidly and that have minor chronic effects.

Such an evaluation must be delayed, however, until such time as the chronic
toxicity candidates have been fully assessed. For the time being, and until

UNLISTED WASTES
Ignitable, Corrosive, and Reactive (I,C,R) Wastes
The RQ of unlisted wastes that exhibit the characteristics of ignitability,
corrosivity, and reactivity (I,C,R), as named in subpart D of RCRA, have been
adjusted to 100 Ibs. The I,C,R wastes represent an indefinable number of
wastes that exhibit the characteristics of ignitability, corrosivity, or
reactivity. Since analysis to identify the I,C, or R ccmponent(s) cannot be
performed, the Agency has assumed that the components present in the hazardous
waste will, on average, fall within the middle tier of the five-tier ranking
system. Accordingly, they are assigned a 100-lb RQ.
An alternate approach would be to examine the RQs of those listed hazardous
wastes for which the RQ has been determined by ignitability or reactivity
alone (corrosivity is not one of the primary criteria; see further discussion
below). The RQ proposed most often for hazardous wastes on the basis of
reactivity is 10 Ibs. The RQ proposed most often for hazardous wastes on the
basis of ignitability is 1000 Ibs. Accordingly, unlisted wastes that are
2-96
-------
reactive would be assigned an RQ of 10 Ibs, while ignitable unlisted wastes
would have 1000-lb RQs. The Agency believes that under this alternate
approach, the selected RQ may not adequately reflect the characteristics
inherent in a hazardous substance. An unlisted waste is often a mixture of
hazardous wastes that may exhibit more than one of the unlisted waste
characteristics, and thus it may not be appropriate to base the proposed RQ on
one particular characteristic. Therefore, the 100-lb RQ assignment on all
unlisted wastes is preferred.
Although the Agency is assigning an RQ to unlisted corrosive wastes, the
characteristic of corrosivity was not used as a primary ranking criterion in
assigning RQs by the SCP procedure described earlier. This has occurred
because no suitable scale has been devised that is readily adaptable to a
multi-tier system, with available data that can be used to rank the pure
substances.
The National Academy of Sciences developed a five-tier scale for "Health
(Cbrrosivity, Skin and Eyes)." (See Table 2-6.) However, examination of the
MAS scale shows that it is a mixture of such criteria as "corrosive to skin"
and "corrosive to eyes" are part of the same scale as dermal toxicity LDc0
values for 24-hour skin contact. Dermal toxicity has been treated in a more
appropriate fashion as one aspect of mammalian toxicity in the SCP procedure.
The RCRA. regulations define the characteristic of corrosivity in terms of pH
ranges and rate of attack on steel (40 CFR Part 261.22, 45FR33122, and
46FR35247), choosing the former "because wastes exhibiting low or high pH can
cause harm to human tissue," among other things (45FR33109). In effect, the
pH scale used by RCRA has only two levels:
Corrosive: pH > 12.5, < 2.0
Noncorrosive: pH 12.5 to 2.0
2-97
-------
There are appreciable difficulties in trying to use pH to establish RQs for
all hazardous substances. The principal difficulty is, of course, that pH
depends on the aqueous solution chemistry of substances rather than on their
properties as pure substances. To use pH in selecting RQs, one would have to
determine the concentrations for all acids and bases that resulted in the
selected pH ranges. In effect, one would be setting RQs based on mixtures
with water, while on the other hand, no criteria would be available for
setting RQs when the corrosives were mixed with nonaqueous substances,
although such mixtures might be of equal or greater corrosivity than the
aqueous systems. Furthermore, seme substances are irritating or corrosive to
human tissue via mechanisms other than attack by acids or caustics.
RTECS reports data from the original version of the Draize tests and minor
modifications thereof, which essentially rank skin and eye irritation on three
levels each (mild, moderate, and severe), using rabbits as the test species.
However, it also reports data from the U.S. Consumer Product Safety Oonmission
version of these tests (16CFR1500.41 and 16CFR1500.42) which simply reports
the lowest level producing an effect, regardless of its severity. These
latter procedures, while having reasonably strict protocols, are also subject
to several modifications, the most cannon being whether or not the test area
is left open to the air or covered during the test period. Trying to develop
a tiered PQ scale on the basis of these tests proved to be impractical because
the numerous variations did not lend themselves to a consistent ranking
process. Rirthermore, numerical data is very sparse. Pbr example, there is
no question that both hydrofluoric and sulfuric acid can cause destructive
skin burns, yet RTECS gives no data on the former, and only eye irritation
data on the latter.
A review of the RCRA waste lists shows that only five have been listed as
exhibiting corrosivity, and none have been listed exclusively because of
corrosivity. These materials are as follows:
2-98
-------
U006 Acetyl chloride (C,R,T)
U020 Benzenesulfonyl chloride (C,R)
U023 Benzotrichloride (C,R,T)
U123 Formic acid (T,C)
U134 Hydrofluoric acid (T,C)
It was accordingly decided that developing a corrosivity ranking scale would
be deferred for the time being and that if they seemed to warrant it, the five
materials above would be subjected to individual review and judgment for
corrosivity, if their ranking by the other factors seemed unsatisfactory. The
RQ status of these substances is as follows:
Substance Proposed RQ Basis Statutory KQ (Ibs)
Acetyl chloride 5000 BHP 5000
Benzenesulfonyl chloride 100 T (ihl) 1
Benzotrichloride 1000 T (ihl) 1
Formic acid 5000 311 5000
Hydrofluoric acid 100 CTX 5000
EP Toxic Wastes
The characteristic of EP toxicity was designed to identify wastes that would
likely contribute to contamination of groundwater by leaching fron landfills.
There are only 14 substances for which the EP toxicity characteristic can be
determined, as listed in 40 CFR Part 261.24. Six of these are specific
compounds (pesticides and herbicides), and RQs for these can be assigned based
on these specific contaminants. RQs for these specific pesticides and
herbicides may be taken fron the values already determined for these compounds
in Tables 8-1 or 9-1.
2-99
-------
The other eight substances, however, while ncminally listed as the metal, must
actually be determined on the basis of some soluble compound of that metal.
The Extraction Procedure (EP) by its very nature dictates that a soluble
species containing the specified metal cation must be determined to be present
in the waste. The suggested projected RQs are those corresponding to the 311
RQs of the corresponding water-soluble salts when availble (i.e., for mercury
and silver). The projected RQ for selenium is based on its inhalation
toxicity. The projected RQ of barium is derived from the fact that the TL -96
of barium hydroxide is given in RTECS as 10-100 ppm, corresponding to an RQ of
1000 Ibs. The projected RQ of the other metals listed as EP toxic wastes is
TBA, since several of their compounds are carcinogenic. The total list,
incorporating all these assignments, is given in Table 2-9.
RQs FOR THE F AND K WASTE STREAMS
Table 9-2 lists the waste-stream substances from RCRA regulations 40 CFR Parts
261.31 and 261.32. These are conmonly called the "F" and "K" waste streams,
referring to the prefix used in the EPA's identifying hazardous waste number.
The RCRA F waste streams (with the exception of F001-F005, which are discussed
separately below) are hazardous wastes from nonspecific sources (e.g., F006
wastewater treatment sludges from electroplating operations). The RCRA K
waste streams are hazardous wastes from specific sources (e.g., K060 ammonia
still lime sludge from coking operations). In order to assign RQs to these
waste streams, the EPA will first examine the hazardous constituents in each F
and K waste stream (i.e., RCRA Section 261, Appendix VII). The next step will
be to identify the RQs associated with each constituent and then assign an RQ
to each waste stream. The RQ will be the lowest RQ associated with the
individual constituents of the waste stream.

For example, assume that RCRA's Appendix VII shows that a K waste stream has
three hazardous constituents—X, Y, and Z. The RQs associated with the
hazardous constituents are:
X = 10 Ibs
Y = 100 Ibs
Z = 1000 Ibs
The RQ for this K waste stream is, therefore, 10 Ibs, the lowest RQ associated
with the hazardous constituents in this waste stream.
The RCPA waste streams F001-F005 are collective listings (e.g., six solvents
are listed collectively under F001). The EPA will assign RQs to the F001-F005
wastes using a special procedure. The RQ assignment for F001 serves as an
example. Six solvents are included under the RCRA F001 listing. RQs will be
assigned to each individual solvent as in the previous example. EPA will also
assign a generic RQ to the F001 listing as a whole, equal to the lowest RQ
assigned to any of these individual solvents. If the releaser is unsure which
solvent he has released or if he has released a mixture of F001 solvents, he
will use the generic F001 RQ for notification purposes.
MIXTURE RULE
Under regulations implementing Section 311 of the CWA, EPA interpreted the
application of RQs to mixtures and solutions containing hazardous substances:
"[discharges of mixtures and solutions are subject to these regulations only
where a canponent hazardous substance of the mixture or solution is discharged
in a quantity equal to or greater than its RQ." [44FR50767, August 29, 1979.D
This interpretation will apply to releases of hazardous substances under
CERCLA as well. Thus, a release of 10 Ibs of solution X which contains 1 Ib
of hazardous substance A and 9 Ibs of nonhazardous substance B is not
reportable if the RQ of hazardous substance A is 10 Ibs. Furthermore, a
2-102
-------
release of a mixture containing 70% of a reportable quantity of hazardous
substance A and 60% of a reportable quantity of hazardous substance B is not
subject to reporting. As noted in the preamble to 40 CFR Part 117, it is not
valid to assume that the toxic properties of all different hazardous
substances can be considered additive. (44FR50767, August 29, 1979.)
An alternative approach would be to apply the RQ to the mixture or solution as
a whole. Ifader this approach, a release of 10 Ibs of solution X which
contains 1 Ib of hazardous substance A and 9 Ibs of nonhazardous substance B
would be reportable, if the RQ of the hazardous substance A was 10 Ibs.
Similarly the mixture containing 70% of a reportable quantity of hazardous
substance A and 60% of a reportable quantity of hazardous substance B would
require a report if released. This approach has not been adopted because it
would result in over-reporting. The Agency would rather focus its attention
on those releases that are potentially more environmentally significant, such
as those releases in which the component hazardous substance is released in an
amount that equals or exceeds the asigned RQ.
RADIONUCLIDES
Radionuclides are hazardous substances under CERCIA because they were
generically designated as hazardous air pollutants under Section 112 of the
Clean Air Act. The Agency will adjust the RQ for radionuclides in some future
rulemaking; until that time, the statutory 1-lb RQ is applicable.
Options for designating and assigning RQs to radionuclides are summarized
here. A detailed analysis of the various options is given in Volume II of
this report ("Radionuclides"). In order to select an approach, the Agency is
considering its own prior experience as well as that of other federal, state,
and international agencies.
2-103
-------
The Agency is considering several options for future adjustments to
radionuclide RQs. Two major related issues are:
* The units the Agency should use to measure RQs, and
* Whether one RQ should be set for all radionuclides or whether
different RQs for specific radionuclides should be used.
EPA recognizes that the pound is not a suitable unit in which to measure the
RQ for radionuclides, because releases much smaller than 1 Ib can seriously
threaten public health and welfare and the environment. EPA is currently
considering two alternative types of measurement units for radionuclide RQs:
dose-equivalent and activity level. Dose-equivalents (usually measured in
rems) is a standard method of comparing biological effects of radiation on
tissue. The activity level of a radionuclide (measured in becquerels or
curies), on the other hand, is a measure of actual number of disintegrations
of radionuclide atoms per unit time.
A list of individual radionuclides which might appropriately be designated
would include over 100 specific substances. The Agency is considering whether
to set one RQ for all radionuclides, or different RQs for specific individual
radionuclides. A generic RQ for all radionuclides might be established in the
form of a dose-equivalent. If the Agency lists RQs for specific
radionuclides, then the RQs could be listed in the form of activity levels.
The effect of a radionuclide depends not only on the number of
disintegrations, but also on the kinds of radiation (alpha, beta, or gamma)
and the energies of each. Thus, different hazards are posed for radionuclides
depending on the different types of radiation emitted and different RQs and
activity levels are appropriate if individual radionuclides are listed.

SECTION 3
ALTERNATE STRATEGIES FOR RQ ADJUSTMENTS AND
ASSIGNMENTS TO THE CERCIA 101(14) LIST
A number of possible strategies for determining RQ values for the designated
substance were briefly discussed earlier (Section ES, pp. ES-5 through ES-9).
The reasons for rejecting all but the SCP process are self-evident for the
majority of those strategies, and such discussions will not be repeated here.
However, one of the strategies, namely the use of a hazard index, was
subjected to an extensive study before it was finally eliminated. Hazard
indices have often been proposed in various reports and technical papers as a
method for comparing hazardous substances, and indeed have been used during
other activities under CERCIA (i.e., the "Mitre Model" used to rank waste
sites).
The discussion that follows provides a detailed summary of studies exploring
the possibility of developing a hazard index suitable for RQ assignments.
HAZARD INDEX DEFINITION AND APPLICATION
A hazard index is a scoring system designed to assess the relative potential
threat to human health and to the environment of chemical substances released
to the air, water, and soil. The system consists of various rating factors
used to examine the types of hazards that may result and, to the extent
possible, the degree of hazard. Each rating factor has a defined rating scale
by which chemicals receive numerical scores based on known data. The rating
factors are combined in an equation to arrive at a single number that is used
to rank a chemical relative to other chemicals processed through the same
equation.
3-1
-------
Analytical Problem
Although the logic for rating hazardous substances appears relatively simple,
thre are a great many complications that exist and that operate to limit the
development of a hazard index. There is not adequate data for each rating
factor, and therefore relative rankings on identical bases would be impossible
to create. Mathematical combinations and permutations abound, with so many
possible alternate formulations of algorithms that there is no general
agreement on how to construct a scientifically acceptable hazard. Finally,
inherent in the formulation of a hazard index is the need to consider all
relevant criteria, and if possible, choose only those that are mutually
independent of each other. Hcwever, when dealing with intrinsic properties of
chemical substances, mutual independence of hazard criteria is difficult, if
not impossible, to determine. For example, a material that is acutely toxic
to mammals may also be acutely toxic to aquatic organisms through some
similarity in the mode of toxic attack.
Development of Alternate Indices for Comparison
Four alternate algorithms have been derived for rating hazardous substances,
and are presented in detail in the following sections. These algorithms
differ in logic and in the number of potential health and environmental
effects parameters considered. The criteria that have been considered to a
greater or lesser extent in development of each of the four alternative
algorithms fall into four general categories, as outlined below:
A. Health Effects
o Carcinogenicity
o Mutagenicity
o Teratogenicity
o Toxicity (human and mammalian)
3-2
-------
B. Human Welfare Effects
o Flarmability
o Explosivity
o Corrosivity
o Reactivity
o Aquatic Toxicity
C. Aggravating Characteristics
o Persistence
o Bioaccunulation
o Toxic Combustion Products
D. Physical and Biological Transformation Characteristics
o Hydrolysis
o Photolysis
o Oxidation
o Biodegradation
E. Environmental Mobility
o Volatility
o Solubility
Algorithm I was deliberately designed to rank chemicals entirely on major
potential health effects. It is a simple additive algorithm comprised of five
components:
HI - (Carcinogenicity) + (Mutagenicity) +
(Teratogenicity) + (Human Toxicity) +
(Mammalian Txscicity)
3-3
-------
Algorithm Ila is slightly more sophisticated in that, in addition to health
effects, it permits evaluation of other adverse effects that may occur (fire,
explosion, reaction) and aggravating characteristics (persistence and
bioaccumulation). In addition, this particular algorithm allows evaluation of
mitigating effects. The basic form of the algorithm is additive and consists
of the following simplifed terms:
HI = Health Effects + Welfare Effects + Aggravating Effects
- Mitigating Effects
Algorithm lib used the same rankings as employed in that immediately
preceding, but uses weighting factors (coefficients) in an attempt to balance
the impact of the individual terms on the final index. The form is as
follows:
HI = W-L (Health Effects) + W2 (Welfare Effects)
+ W_ (Aggravating Effects) - W, (Mitigating Effects)
It is apparent that one must be very careful in assigning weighting factors so
as not to overrate certain criteria, and therefore create artificial values
that are so large from one factor that the input from other important criteria
becomes insignificant in comparison.
Algorithm III is an extension of the second. It is comprised of essentially
the same rating factors; however, the mathematical approach is different.
Rather than being strictly additive, it incorporates multplicative
arrangements to arrive at a final rating. This third algorithm takes the
following form:
3-4
-------
(Health Effects) x (Aggravating Health Factors)
+ (Welfare Effects) x (Aggravating/Mitigating
Transformation Properties)
The fourth algorithm was similar to the second in form, but differed in that
it considered solubility and volatility (environmental mobility) rather than
other mitigating factors, and included media-specific toxicity evaluations
(e.g., inhalation, oral, and dermal toxicities). The form of algorithm IV is
as follows:
HI = (Health Effects) + (Welfare Effects) +
(Environmental Mobility) + (Aggravating Characteristics)
Details of the ranking schemes and numerical assignments for each individual
criterion and component of these indices will not be presented in this report.
To test and compare the indices, 27 hazardous substances, selected to
represent a wide range of dangerous properties, were evaluated via each index,
and then the relative rankings within each index were determined. For each
algorithm, the substance with the highest HI value was taken to be the most
hazardous and therefore was assigned a relative rank of 1. The substance with
the next highest HI value was assigned a relative rank of 2, and so on. If
two or more substances shared the same HI value, then each received an
identical ranking. In such cases the next relative rank assigned was equal to
the last relative rank assigned, plus the number of identical rankings. The
following from Algorithm I should serve as an example:
3-5
-------
Hazardous Substance HI Value Relative Ranking
N-Nitrosodimethylanune 12 1
Carbon Disulfide 11 2
Chloroform 11 2
Phosphorus (White) 11 2
Acrolein 10 5
The final relative rankings for the 27 substances by all algorithms is given
in Table 3-1.
The rankings presented in Table 3-1 highlight the problems with hazard
indices, and reemphasize the complications pointed out earlier. It is
irttnediately evident that there is no consistency in the way the indices rate
different compounds.
In conclusion, it does not appear that standardized hazard indices can readily
be adapted to the assignment of RQs. Until such time as data gaps are
eliminated and a "standardized" index—as well as "standardized" ways to rate
the various individual factors—are developed (perhaps by interagency study
and the adoption of suitable conventions), the use of such indices is not
recortmended.

SECTION 4
ADMINISTRATIVE CONSIDERATIONS
ADMINISTRATIVE FACTORS
The legislative history of CERCLA makes it very clear that in setting
"administrative feasibility and practicality should be primary factors," and
that "a single quantity is to be determined for each hazardous substance." The
Senate Report 96-848, issued by the Ccranittee on Environment and Public Works
to accompany S.1480, states:
The provision intentionally emits from the requirement to determine
"reporting" quantities any reference to harm or hazard. A single
quantity is to be determined for each hazardous substance, and this
single quantity requires notification upon release into any
environmental medium. It would be virtually impossible to determine a
single quantity applicable to all media while at the same time linking
such quantity to any subjective concept of harm.
It is essential that such quantities be relatively simple for those
subject to notification requirements to understand and comply with.
Since releases in such quantities trigger notification requirements,
but do not, in and of themselves, give rise to other liabilities under
this Act, the President's broad discretion to select quantitites will
not unfairly burden those persons subject to the Act.
In determining reportable quantities under this paragraph, the
President may consider any factors deemed relevant to administering
the reporting requirements or the President's other responsibilities
under this Act. Administrative feasibility and practicality should be
primary factors. In addition, the President may revise such
regulations from time to time if under-reporting or over-reporting is
occurring under existing regulations, (p. 29)
Section 102 requires the Administrator to promulgate regulations establishing
RQs for hazardous substances. Congressional intent was clearly to vest the
Administrator of the EPA with broad authority and considerable discretion to
adjust the RQs from either those assigned under CWA Section 311, or the 1-lb
quantity statutorily assigned to all other Section 101(14) hazardous substances.
4-1
-------
The term "administrative feasibility and practicality" may be interpreted in a
very broad sense to include any practical factors deemed relevant to
administering the Act.
Although the RQ adjustment process proposed herein rests on scientific and
technical criteria based on some considerations of practicality an3
administrative feasibility, in the future the EPA may choose to modify the RQs
based on still other administrative factors. None of the factors discussed
below has actually been used to modify the RQs proposed following the procedure
of Section 2. Implementation of such modification of the RQs will be done, as
appropriate, on a case-by-case basis, taking into account those factors that are
deemed relevant by the Administrator at the time the RQs are modified. Despite
the fact that there are currently no specific methods for applying seme of these
factors, it is possible that as experience with the notification requirement of
CERCLA Section 103 is acquired, the Agency may develop mechanism(s) for
employing administrative feasibility and practicality factors discussed below.
The factors may include, but are not limited to, any or all of the following:
1. Release history
2. Release potential
A. Spill frequency
B. Price
C. Production volume or available quantity
D. Container size
Any one or more of these factors may have an overriding effect on the RQ to be
assigned to a particular hazardous substance for CERdA. General approaches to
4-2
-------
applying each of these factors are suggested below.
Release History
Although the NEC, EPA, and Coast Guard districts have received hazardous
substance spill notifications for several years, the data on release history are
limited and are not consistently catalogued or filed. The CWA Section 311
substances released into navigable waters and transportation-related releases
provide a substantial history of release patterns, but not all the CERCIA
substances have been subject to reporting requirements pursuant to CWA Section
311. Analysis of release history would evaluate past releases to determine how
often a response was necessary, and, if so, what type of response was required.
As the Agency gains experience in handling reports of releases of CERCIA
hazardous substances, it may find that seme substances are frequency released in
situations that require an emergency response. Such release history might be
used to adjust RQs. For example, if the EPA has, in the past, responded to
100-lb releases of hazardous substances, a 100-lb RQ may be appropriate.
Several factors either describe the tendency of hazardous substances to enter
the environment or are related to that tendency and therefore may be employed to
modify the RQs arrived at using the strategy outlined in Section 2. A possible
way of using those factors is to raise the RQ proposed herein for those
substances with a much lower than average release potential. In deciding
whether release potential is much smaller or much larger than average, those
substances are to be compared which fall in the same RQ tier based upon the same
primary criterion. For example, RQs of substances that have 100-lb RQs because
of their aquatic toxicity and which have much lower than average release
potential may be administratively raised.
Several factors may be used to predict the likelihood that hazardous substances
will be released into the environment. These include: (1) price, (2)
production volume or available quantity, (3) distribution mode, (4)
4-3
-------
transportation mode, and (5) packaging and containerization. The Agency might
raise the proposed RQs for substances that are more likely to be released.
1. Price. Expensive substances may be handled in a fashion that will
minimize the likelihood that the substances would be released or
discarded as wastes (from which a later release could occur). When a
relese of one of these substances does occur, the releaser may have an
economic incentive to clean up the release to recover the substance.
Substances more expensive than average might therefore be given higher
RQs.
2. Production volume or available quantity. Substances produced in higher
volume may be released more often than substances produced in low
volume, and may therefore require lower RQs than the low-volume
substances.
3. Distribution mode. Some hazardous substances are produced exclusively
as intermediates for use in the same plant location which produces the
intermediates. Other hazardous substances may be produced at locations
that are fairly close to the plants at which they are consumed and
converted into other substances. Where only a few plants produce the
hazardous substance or where the consuming plants are either at the
same site or nearby, the RQ suggested on the basis of the primary and
secondary criteria may be relaxed because of the relatively small risk
of release from the limited distribution of the hazardous substance.
4. Transportation mode. The mode of transportation, e.g., rail, truck, or
barge, may have an influence on the likelihood of a release. If some
hazardous substances are generally shipped by a transportation mode
that exposes them to a particularly high risk of release, the RQ may be
reduced; on the other hand, hazardous substances that are primarily
shipped by safer modes of transportation might have their RQs
increased.
4-4
-------
5. Packaging and containerization. The method of packaging of the
hazardous substance could be used to modify the RQ. Substances that
are usually packaged in a fashion that substantially reduces the risk
of release (such as very high-priced substances) may be assigned RQs on
the basis of the smallest package size. Substances that are usually
shipped in large containers may be usually released in quantities that
are related to the container size. For example, a release fron a tank
truck is more likely to involve a large quantity of a substance than is
a release from a case of 1-lb bottles. The RQs might therefore be set
on the basis of container size for some substances.
The above administrative factors may be used in the future to revise the
technically adjusted RQs presented in this report. An administrative factor
considered earlier for possible application to RQ revision, Which has been
rejected, is ease of cleanup. EPA is not including this criterion because ease
of cleanup does not guarantee that the releaser will actually take cleanup
action, nor do unique cleanup requirements necessarily mean that the releaser
will not take proper response measures.
4-5
-------
SECTION 5
AQUATIC TOXICITY
This section of the report is aimed at providing supplementary information to
those who desire a broader understanding of the concept of aquatic toxicity.
Readers are reminded, however, that RQs derived on this basis are not intended
to be measures of harm. The RQ is intended to serve as a trigger for
notification and not as a response action level. RQs only alert OSCs that
they should evaluate a release situation to determine if a response is
warranted.
INTRODUCTION
During the past 25 years, aquatic bioassay has beccme an important tool for
determining the effects of environmental conditions and toxicants on species
living in lakes, rivers, estuaries, and oceans. An aquatic bioassay is any
test whose objective is to determine the effects of one or more substances,
wastes, or enviromental factors (e.g., pH, dissolved oxygen, light), alone or
in combination, on aquatic organisms (Ref. 5-1). Such tests, While conducted
in the laboratory, can be made to simulate in-situ conditions so that the
observed effects can be generalized to the field environment.
Aquatic bioassay, which tests the effects of toxicants on organisms, provides
important information that is useful for protecting the aquatic environment,
which chemical examination alone cannot. The results from aquatic bioassay
tests of a toxicological agent are used to determine both acute and chronic
effects. For example, such tests can be used to determine the acute and
chronic sensitivity of a single species to a number of toxicants, the relative
acute and chronic sensitivities of a number of species to a single toxicant,
and the maximum allowable toxicant concentration which causes no long-term
negative effects, and the maximum allowable toxicant concentration for very
5-1
-------
short exposures (e.g., slugs or periodic discharges).
Further, by carefully choosing the species and the bioassay test procedure,
estimates of the effects of a toxicant on an ecosystem can be made based on
bioassay results using a single species (Ref. 5-2). For example, by choosing
a test species of critical importance in an ecosystem food chain (e.g., an
alga or a sensitive fish species), one can conclude from the bioassay data
that a concentration of the toxicant which causes significant death of the
critical species within a specified time period will have a severe negative
impact on the ecosystem.
In recent years, the procedures for conducting aquatic bioassay tests have
become standardized. Many of the procedures are promulgated in Ref. 5-1.
Widespread use of standard procedures will promote a large data base of
comparable data, and a basis for reproducing critical data. Much of what
follows is based on the standard methods and procedures found in the
scientific literature. The following sections discuss the nomenclature,
methodology, and significance of aquatic bioassay utilizing toxic substances,
including wastes.
NOMENCLATURE
Aquatic bioassay is concerned with determining the effects of a toxicant or
combination of toxicants of specified concentration for a specified period of
time on a species of organism. The key words are "effects," "concentration,"
and "time."
The effects of a toxicant on an organism can be manifested in a number of ways
including but not limited to:
1. Death
2. Paralysis
3. Deformity
5-2
-------
4. Resistance to disease
5. Developmental abnormality
6. Lowered reproductive capacity
7. Impairment of other bodily functions
8. Loss of other competitive abilities
When death is the criterion of toxicity, the bioassay is conducted to
determine the lethality of varying concentrations of the toxicant (the LC or
lethal concentration). When a criterion other than death is of interest, such
as 2 through 8 above, the bioassay can be used to determine the influence of
toxicant concentration on these (EC or effective concentration). Only in
extremely rare cases is lethal dose (LD) or effective dose (ED) used in
aquatic bioassay, since poisoning of aquatic organisms usually occurs through
diffusion of the toxicant into the tissues from the aqueous medium, rather
than by ingestion.
A numerical suffix and prefix always accompany the LC or EC designation. The
suffix is the percentage of organisms experiencing death (for LC) or some
other effect (for EC) at the designated concentration. The prefix is the
duration of the bioassay. For example, 96-hour LC,.-. = 100 ppm means that 50%
of the test organisms exposed to the toxicant at 100 ppm would be expected to
die within 96 hours (a 96-hour bioassay is usually used to measure acute
toxicity).
Recent standard aquatic bioassay procedures (Ref. 5-1) specify the use of LC
and EC when reporting results. HDwever, much of the literature on aquatic
toxicity contains median tolerance limits, or TL . When lethality is the
criterion of toxicity, the TL = LCcrv. When a nonlethal criterion is used,
m DU
then TLm = EC^Q. However, it should be understood that the tolerance limit
specifies the percentage of organisms able to tolerate exposure to the
toxicant over the duration of the test. Thus, for example, TL = ^C^ (for
5-3
-------
death) and TL__ = ECiri (for nonlethal effects).
yu lu
There are several other important parameters that can be gleaned frcm aquatic
bioassay. The first of these is incipient lethal level, also called the
incipient I£5Q. Ibis is the toxicant concentration at which 50% of the test
organisms can be expected to die on long exposure (Ref. 5-3). Incipient EC50
values are also reported. Such bioassay tests require long-term testing, on
the order of months to years, depending on the life cycle of the test
organisms. A 96-hour I£50 and a° incipient ICe0 can be two vastly different
numbers with vastly different meanings.
The most important values frcm an environmental viewpoint that are obtainable
from long-term aquatic bioassay are the safe concentration (SC) and the
maximum allowable toxicant concentration (MATC). The SC is the maximum
concentration of a toxicant that has no observable harmful effects after
long-term exposure over one or more generations. The MATC is the
concentration of toxic substance that may be present in the receiving water
without causing significant harm to its productivity and all of its various
uses. Both the SC and MATC are used as standard water quality criteria.
MEMHODOLOGY
Aquatic bioassay testing exposes individuals of a species of organism to
various concentrations of a toxicant for a predetermined period of time or
until a specific effect is observed. The effect each concentration has on the
individuals is determined, and through statistical means the LC, EC, SC, or
MATC values are derived, depending on the type of bioassay performed.
Aquatic bioassay procedures are often categorized by duration, which includes
snort-term, intermediate-term, and long-term tests. Short-term aquatic
bioassay tests are of two types: rangefinding and definitive. Rangefinding
short-term bioassay is used to screen a toxicant for proper concentrations to
be used for longer term testing. Definitive short-term bioassay can be used
5-4
-------
to determine acute LC and EC values, the relative toxicity of a number of
toxicants on a single species, or the relative sensitivity of several species
to a single toxicant.
Intermediate-term aquatic bioassay is used to determine incipient iJCcn and
incipient EC5Q values, the sensitivity to toxicants of selected life stages of
long-lived species, or to indicate the toxicant concentrations to be used in a
long-term bioassay.
Long-term aquatic bioassay is frequently performed when SC or MATC values are
desired. Additionally, incipient EC values can be obtained for effects that
require long periods to be manifested, for example, effects on:
1. Growth
2. Reproduction
3. Maturation
4. Bioaccumulation
5. Behavior
Short and intermediate bioassay can be performed using static, renewed, or
flowthrough conditions. Long-term bioassay is usually performed as a
flowthrough test.. A static bioassay test uses the same aqueous test solution
throughout. Static testing is not useful when it would be difficult to
maintain the toxicant concentration over the duration of the test (e.g., when
a volatile toxicant is used). In such cases, the aqueous test solution can be
periodically renewed (e.g., every 24 hours), which will help to maintain a
constant concentration.
Flowthrough bioassay is the most desirable type, since a constant toxicant
concentration is assured and field conditions can be simulated. HDwever, the
experimental apparatus is immensely more complicated and costly than that used
for static bioassay. Ihe apparatus includes water reservoirs, pimps, drains,
5-5
-------
diluters, etc. Some species, for example those of the phytoplankton (the
free-floating plants) are difficult to bioassay under flowthrough conditions
because they are easily swept away.
Test Species
Aquatic bioassays can be performed using species representing all aquatic
phyla due to refinements in culture techniques that have taken place in recent
decades. When it is known that a particular chemical will be discharged into
a receiving water (for example when a chemical processing plant is sited next
to a river), bioassays should be performed on the most sensitive local
species.
However, during aquatic toxicity screening of chemicals when the ecosystem
into which the chemical may ultimately be discharged is unknown, the tendency
is to perform bioassays on standard species, particularly species of fish.
The rainbow trout (salmo gairdneri Richardson) is a good representative
species of a cool, fresh-water fish which is now used worldwide in aquatic
bioassay. The fathead minnow (Pimephales prcmelas Rafinesque) is used
extensively in the United States, particularly for sublethal bioassay
involving reproduction. Similarly, the bluegill (Lepomis macrcchirus
Rafinesque) is widely used in the United States. The common goldfish
(Carassius auratus [L.]) may become a standard fish, primarily because of its
availability (Ref. 5-4). Evidence suggests that using the results fran
bioassays with standard fish to predict the effects on other species of fish
is defensible since the variability in results between fish species is often
less than the variability observed when the same species is tested in
different waters (Ref. 5-4). Ifcwever, there is also great variability among
aquatic species to the same pollutant.
5-6
-------
SIGNIFICANCE
Aquatic bioassay methods have been refined over the years so that current
procedures yield data that provide good estimates of the impacts that
chemicals have on the aquatic environment, based on the bioassay results from
one or several sensitive, critical organisms. Thus, aquatic toxicity derived
from aquatic bioassay provides a basis for assessing the impacts of chemical
insults to the aquatic environment.
Recognizing this, the EPA used acute aquatic toxicity (96-hour LCcO) as one of
the criteria in designating the substances in the Clean Water Act, for
determining the reportable quantity of each, and for calculating the rates of
penalty when a designated substance was released into the environment in an
amount equal to or greater than its RQ (Ref. 5-5).
Five ranges of acute toxicity define the degree of toxic hazard in the Clean
Water Act. These are:
Toxicity Range
Category 96-Hr LC,.^ rug/Liter
•n • in -• __«T_ •• __ _. __ _ 9u
X Less than 0.1
A 0.1-1
B 1-10
C 10-100
D 100-500
EPA used the 500 mg/1 96-hour I£50 as the criterion for environmental damage,
based on historical spill data and the consensus of a panel of experts. These
data showed that fish kills had consistently occurred when substances with
96-hour kCcf\ values greater than 100 mg/1 were spilled. However, spills of
substances with 96-hour I£c0 values greater than 500 mg/1 consistently showed
no evidence of environmental damage in the form of fish kills (Ref. 5-5).
Thus, using acute aquatic toxicity as one factor in determining Superfund
reportable quantities for the aquatic medium has precedence in regulations
pursuant to the Clean Water Act. Additionally, using a 96-hour LCc of 500
5-7
-------
mg/1 criterion for environmental damage has precedence under the Clean Vfoter
Act.
It must be emphasized, however, that LC, EC, SC, or MATC values are
species-specific and cannot, without some error, be generalized to members
even of the same class (e.g., bluegill data to other fish), and cannot,
without great error, be generalized to other classes of organisms. Thus, it
is untenable to use aquatic toxicity data to predict hazards to terrestrial
organisms, including humans. To illustrate, Table 5-1 shows the difference in
toxicity to rats (mammal), mallards (bird), and bluegill (fish) of three
pesticides: Parathion, Methyl parathion, and Guthion.
TABLE 5-1. TOXrCITIES OF COMCN
INSECTICIDES (FRCM REP. 5-2)
Male Rat LD50 Mallard LDg- Bluegill 96-hr
Pesticide (mg/kg) (oral; (mg/lcg)(orai) TL^ (ug/L)
Parathion 13 2.13 95
Methyl
parathion 14 10 1900
Guthion 13 136 5.2
There is little difference in the toxicity of the three pesticides to rats.
Mallards find Methyl parathion approximately 5 times less toxic than
Parathion, and Guthion approximately 13 times less toxic than Methyl
parathion. Bluegill are nearly opposite in their sensitivity to the
pesticides. Guthion is the most toxic, Methyl parathion the least toxic, and
Parathion of intermediate toxicity. The data presented in Table 5-1 show that
generalizing the toxicity of these three pesticides to rats and mallards based
on toxicity to bluegills would be completely erroneous. Using the toxicity
data frcm the rats or mallards to predict toxicity to the other two species
would be equally fallacious.
5-8
-------
The reasons for such inconsistent relative toxicities of the three pesticides
to the three different species which represent three different classes of
animals are differences in rates and processes of metabolic activation or
detoxification and general differences of metabolic pathways of these species.
Aquatic toxicity data has been used as one criterion for selecting Superfund
reportable quantities. It is useful for predicting aquatic environmental
impacts when chemicals are spilled into these systems, and has precedence in
the Clean Water Act. Using the 500 mg/1 96-hour LC_ as the criterion for
environmental damage is supported by historical spill data. Since there are
other potential hazards that the Agency desires to address, aquatic toxicity
is only one component in the SCP strategy that includes mammalian toxicity,
chronic toxicity, carcinogenicity, ignitability, and reactivity.

SECTION 6
MAIWALIAN TOXICITY
This section of the report is aimed at providing supplementary information to
those Who desire a broader understanding of the concept of mammalian toxicity.
Readers are reminded, however, that RQs derived on this basis are not intended
to be measures of harm. The RQ is intended to serve as a trigger for
notification and not as a response action level. RQs only alert OSCs that
they should evaluate a release situation to determine if a response is
warranted.
INTRODUCTION
Bioassay testing using nonhuman mammals is used extensively for assessing the
toxicity of chemicals. The primary goal of such tests is to estimate the
toxicity of chemicals to man. The accuracy of predicting human sensitivity to
a chemical based on the sensitivity of, say, a rat, varies with a number of
factors relating to the chemical itself, the test conditions, and differences
between the test organism and man. Efforts should be made to conduct such
tests using consistent test conditions and procedures that facilitate
extrapolation to man.
Mammals - those animals that nourish their young with milk supplied by mammary
glands and that have skin which is more or less covered by hair - represent a
single class of vertebrate animals. Mammals share basic characteristics of
appearance, anatomy, and perhaps most important, physiology.
It has been demonstrated from accidental human exposure to toxic chemicals
that using nonhuman mammal bioassay results to predict human toxicity is
reasonably accurate for many chemicals, and since there are very little data
concerning toxicity testing on humans, it is the best method available for
6-1
-------
assessing potential chemical hazards to humans. With sane chemicals 10- to
12-fold differences in susceptibility to toxicants between mice and humans has
been observed (Ref. 6-1).
The following sections discuss the nomenclature used in toxicity testing using
mammals, the methods employed for these tests, and the significance of
mammalian toxicity data for establishing Superfund multimedia reportable
quantities .
NCME1JCIA1URE
Mammalian toxicity testing, like aquatic toxicity testing, is concerned with
both lethal and sub-lethal (toxic) exposure effects. The toxicant is
administered to the test animal by various routes of administration, including
vapor form as an inhalant (at a given concentration), by applying the toxicant
topically to an external surface of the test animal (at a given dosage), or by
placing the toxicant into the body of the test animal (at a given dosage).
Thus when death is the criterion of toxicity, mammalian toxicity data is
expressed as lethal concentration (LC) if the toxicant is an inhalant, or
lethal dose (ID) if the toxicant is placed on or in the body. When a toxic
effect other than death is the criterion of toxicity, a toxic concentration
(TC) designation is used for toxicants administered as an inhalant, and toxic
dose (TD) for those administered on or in the body.
The LC, ID, TC, and TD designations are followed by a numerical suffix. For
example (from Ref. 6-2):
I£,-0-Lethal Concentration Fifty - a calculated concentration of a
substance in air, exposure to which for a specified length of time is
expected to cause the death of 50% of an entire defined experimental
mammal population.
Dose Fifty - a calculated dose of a substance which is
expected to cause the death of 50% of an entire defined experimental
manual population. It is determined from the exposure to the substance
6-2
-------
by any route other than inhalation.
Cbncentration Fifty - a calculated concentration of a
substance in air, exposure to which for a specified length of time is
expected to produce toxic effects in 50% of an entire defined
experimental manmal population.
Dose Fifty - a calculated dose of a substance vtfiich is
expected to cause toxic effects in 50% of an entire defined experimental
mammal population. It is determined from exposure to the substance by
any route other than inhalation.
It should be noted that percentages other than 50% (e.g., I^10) are reported
in the literature.
Review articles or conpendiums of toxicity data (e.g., Ref . 6-2) often report
1C- , ^V,-,' "^To' or ^io va^ues> These are the lowest reported values frcrn
the literature (either concentrations or doses) which cause either death or
other toxic effects.
For ID or TD, the dosage units are usually given in quantity of toxicant per
unit body weight (e.g., mg/kg). When dermal administration of the substance
is used, results may be expressed as quantity of toxicant per unit area of
2
skin (e.g., mg/cm ). For LC or TC, concentrations are generally listed as
parts per million (ppm) in air on a volume/volume basis when the toxicant is a
gas, or as weight of toxicant per volume of air (e.g., mg/m ) when the
toxicant is an airborne liquid or solid.
Other important data are reported along with the toxicity data values,
including the duration of the exposure, if the exposure was continuous or
discontinuous, and the frequency of the exposure. For exarrple, an experiment
might require that mice be fed twice daily over a 6-week period with food
dosed with the toxicant every other week. Complete reporting of experimental
conditions is required so that tests may be accurately reproduced and data
accurately compared.

METHODOLOGY
The following discussion of the method employed in mammalian toxicity testing
is divided into sections on general considerations, routes of toxicant
administration, toxic effects which are cormonly observed, and the test
species which are often used for such testing.
General Considerations
Mammalian toxicity testing is performed to determine the effects, both lethal
and sub-lethal, of chemicals. Testing must be performed using strict
procedures and protocol, including accurate dosing equipment, cleanliness, and
minimal external stresses to the test animals. For example, rats which are
housed singly develop high blood pressure (Ref. 6-3) which affects the
metabolism of chemicals. Overcrowded conditions also can create stress.
Of utmost importance in mammalian toxicity testing is the existence of a
control group of animals which is treated in exactly the same manner as the
test group. The sole experimental variable between the two groups is the
administration or non-administration of the toxicant.
Toxicant Administration
Toxicants are administered either topically, via inhalation, or orally in many
mammalian toxicity tests; however, other methods of internal administration
are used (e.g., intravenously, intramuscularly, and intraperitoneally).
Topical administration is either to the eyes (ocular) or to the skin (dermal),
which may be intact or abraded. These tests are used to determine both
sub-lethal toxic effects (e.g., skin or eye irritation, systematic effects)
and lethal toxic effects, either acute or chronic.
6-4
-------
Administration of toxicants by inhalation is achieved by placing the animals
in a test chamber whose atmosphere is dosed with the toxicant, via mask, or by
cannulation (intubation of the respiratory tract). Lethal, sub-lethal, acute
and chronic effects can be determined using this method of toxicant
administration.
Oral adminsitration of toxicants is achieved by dosing either the food or
water, via capsule or tablet, or by intubation into the stomach. Lethal,
sub-lethal, acute, and chronic effects can be determined using this method of
toxicant administration.
The method chosen for adminstration of the toxicant will, in part, depend on
the mode of entry of the toxicant most likely to be encountered in the
environment. For example, polychlorinated biphenyls (PCBs) pose risk when
absorbed through the skin and when ingested. Both modes of exposure are
possible with PCBs since they are found in transformer oils and drinking
water. Therefore, skin application and oral ingestion methods of
administration are used in toxicity testing of PCBs.
Toxic Effects
Sub-lethal or toxic effects of exposure to chemicals can be manifested in a
number of ways and in a number of organs. Toxicants can irritate the skin or
eyes (indicated by redness or bleeding). Exposure can produce tumors in or on
the body which can be benign or malignant. The functioning of organs can
decrease or increase. Exposure can result in aberrations in the offspring of
those exposed (teratogenicity). Changes in behavior may be brought about
after exposure to toxicants.
6-5
-------
Test Species
A wide variety of mammals are used in toxicity testing. Tto of the roost
carmen species are mice and rats. These species are popular because
individuals of "known genetic background are easily obtained and they are
relatively inexpensive. Cost is an important consideration since extensive
testing can require thousands of animals.
Other mammalian species used in toxicity testing include:
Cat Guinea Pig
Cattle Hamster
Horse Monkey
Dog Pig
Goat Rabbit
Sheep Squirrel
SIGNIFICANCE
Reportable quantities are assigned based on toxicity to norihuman animals.
This is necessitated by the fact that little in the way of reliable data
exists on human toxicity from most chemicals. There are toxic effects which
are not easily observed in animals, but clearly manifested in hvmans. For
example, exposure to many chemicals can cause changes in behavior. It is
difficult, if not impossible, to observe subtle behavior changes in animals,
and therefore such toxic effects could be missed. Additionally, there is
relatively little chronic toxicity data available in which the test species is
exposed to snail amounts of the toxicant over long periods of time, although
such conditions are occasionally simulated. Such long-term studies are
exceedingly costly to perform. In this report, less than a third of the
substances have concrete evidence for chronic toxicity, and not all of such
evidence will be adequate for RQ assignment.
6-6
-------
Despite the limitations in the use of nonhuman marttnalian toxicity data for
predicting subtle effects in humans, the use of the gross effect (namely,
death) and the resultant conparison of chemical toxic effects on the basis of
lethal doses (LD50s) has much to reccramend it. Such values will generally
fall in the same range for a wide variety of mammalian species, and may thus
be extrapolated to humans with a high degree of certainty. Furthermore, LDcQ
values are replicable with the use of standard test protocols and standard
strains of the various species. Finally, where accurate comparisons are
important, test population sizes may be increased to improve the validity of
the data from a statistical point of view.
The FQ strategy allows one to base decisions on factors other than mammalian
toxicity, and to select RQ levels based on other factors, such as aquatic
toxicity, carcinogenicity, ignitability, and reactivity, and to make further
adjustments on the basis of biodegradation, hydrolysis, or photolysis. These
factors may be used to assign RQs in the absence of mammalian toxicity data,
or to assign RQs lower than that indicated by marmalian toxicity whenever
appropriate.

SECTION 7
DATA MANAGEMENT SYSTEM
THE N3H/EPA CHEMICAL INFORMATION SYSTEM (CIS)
Fein-Marquart Associates, Inc., Baltinore, MD, conducts a program to design,
develop, implement, install, and maintain the CIS for the EPA, the National
Institutes of Health, and the National Bureau of Standards. The CIS is a
collection of computerized data storage and retrieval nodules for chemical
information. Each of these modules is essentially a "stand-alone" system
dealing with a particular aspect of chemistry. However, they are all prepared
according to a standard Set of CIS guidelines so that they can share the same
utility software and communicate among each other. In this way it is
relatively easy to conduct composite searches dealing with these various
aspects of chemistry, and similarly to display, in association with retrieved
compounds, information stored in the data bases associated with the various
modules.
The modules (components) of the CIS are listed below, and the structure of the
CIS is depicted in Figure 7-1.

The modules of the CIS cotntunicate among themselves by stored lists of
Registry Numbers, for the most part supplied by Chemical Abstracts Service.
In the case of some modules, for example CTCP, WaterDROP, and Federal Register
Search System, the retrievals are, more exactly, represented internally by
"Citations," where each citation contains a specific reference to a compound
(represented by its Registry Number). A given list of citations is
automatically converted to a list of the pure Registry Numbers of all the
compounds referenced in that list when it was generated. In some modules,
where more than one "entry" for a Registry Number is possible, a subidentifier
is appended to the Registry Number. As an example, there are cases when more
than one crystalline form for a compound exists, and therefore, more than one
entry for a compound might be found in a list of one or more Registry Numbers
being generated and stored. For instance, within the Structure and
Nomenclature Search System (SANSS) one might ask for all compounds containing
a particular structural fragment, or with a name or synonym containing broad
criteria. The answer to each such query is a stored file containing a list of
the Registry Numbers for those canpounds satisfying the criteria specified.
For essentially all the compounds in the CIS the following information is
available:
* CAS Registry Number
* Structure
7-3
-------
* The chemical name and molecular formula in accordance with the
introductory sections of the Toxic Substances Control Act, Chemical
Substances Inventory, Volume 1, May 1979
* CAS Index Name(s)
* A list of sources of further information
* Other names and synonyms by which the substances are cottnonly known
in conmerce and manufacturing
In addition, as described in the following sections, much additional
information, e.g., mass spectrum, toxicity data, regulation, is also available
for many of the compounds.
The following sections will discuss briefly the features of each of the CIS
components that are most useful to the Reportable Quantities program. For an
overview of CIS and descriptions of other components, as well as insight into
other applications of the system, the reader should consult recent descriptive
publications (G.W.A. Milne, C.L. Fisk, S.R. Heller, and R. Potenzone, Jr.,
Science, 215, 371-375, 22 January 1982).
Oil and Hazardous Materials/Technical Assistance Data System (OHM/TADS)
OHM/TADS is a collection of interactive computer programs that allow searching
of the EPA's Oil and Hazardous Materials/Technical Assistance Data System
(OHM/TADS). This data system provides necessary technical support for the
assessment of potential or actual dangers encountered as a result of the
discharge of oil or hazardous substances. OHM/TADS contains data for any
material which has been designated an oil or hazardous material by the EPA.
Currently, there is information in the system for about 1100 substances.
While the primary function of this data base is to provide emergency
information to spill response team personnel, it can also be regarded as a
7-4
-------
general source of diverse information on hazardous substances. OHM/TADS data
has been gathered from the open literature.
OEM/TADS searches are based on the 126 subjects into which all information in
the data base has been categorized. These subjects are generally referred to
as "fields." For example, the MAT field contains the material name, and the
DRK field contains the recommended drinking water limits. Every material in
the data base has information in the MAT field, but information may not be
available on every subject for the material of interest. Perhaps the
necessary measurement has not been made; for example, the boiling point (BLP
field) may not be known. One can list all of the information available for a
particular chemical or restrict the listing to only the fields of interest.
OHM/TADS allows a search for materials with certain values of specified
properties (for example, the specific gravity or vapor pressure) or ranges of
those properties. OHM/TADS also provides reccmmended methods for disposing of
spilled materials (the DIS field), and for notifying proper authorities (DSN
field).
Structure and Nomenclature Search System (SANSS)
The SANSS module data base is designed to contain an entry for each compound
included in the data bases associated with the other individual CIS
components. Each such entry includes, as available: CAS Registry Number;
systematic name (8th CI and/or 9th CI); synonyms and trade names; molecular
formula; connection table, and references to other sources of information.
Currently there are approximately 200,000 substances in the data base. One
can query this system for compounds having a wide variety of characteristics.
For example, one can search for all compounds having a specific structural
fragment contained within it. To accomplish this, the user describes the
two-dimensional structural fragment by means of simple typed commands. The
system can also be searched on the basis of name (either complete or partial);
ring system; specific functional groups; molecular formula (complete,
7-5
-------
partial, or ranged); molecular weight, and atom count.
Acute Tgxicity Data from the NIOSH Registry of
Toxic Effects of Chemical Substances (RTECS)
The search and retrieval system for the NIOSH Registry of Toxic Effects of
Chemical Substances (RTECS) is based on the NIOSH publication of the same
name. Each quarter, a completely updated magnetic tape copy of the RTECS
publication is processed, and the data base for the interactive search and
retrieval system is replaced. Currently there is information in the system
for almost 50,000 compounds.
The direct search allows the user to display, for a given list of compounds,
the CAS Registry Number, the RTECS Registry Number, and the details of each
published toxicity measurement for each compound, including literature
references.
Alternatively, the user may ask for all entries relating to specific end
effects (e.g., eye irritation) on specific classes of animals (e.g., rabbits)
for specific means of application, having dosage within a given range. The
result of such a query is a list of Registry Numbers that can then be used to
display RTECS data or to obtain information frcm other modules of the CIS.
Clinical Toxicology of Commercial Products (CTCP)
CTCP is an on-line interactive data base based on the book of the same title
by Drs. Gosselin, Hodge, Smith, and Gleason. In it is contained information
about approximately 20,000 commercial products, consisting of their
manufacturer, uses, and composition. For the chemicals comprising a product,
the CAS Registry Number, concentration, and indication of toxicity (if
applicable) are given. As any consumer knows, the composition of a product is
subject to change from time to time, even if the trade name under which it is
marketed remains the same. However, it is often critical to know the
7-6
-------
composition of earlier versions of a specific product—for example, in the
case where a child may have ingested the contents of an old bottle. Thus,
prior formulations are retained whenever possible.
The data base may be searched against essentially all of its fields. Etor
example, one might inquire about all conpounds containing phosphoric acid that
are used as fertilizers.
Toxic Substances Control Act Plant £ Production Data (TSCAPP)
The TSCAPP data base is the production and plant site information associated
with the TSCA Chemical Substance Inventory: Initial Inventory. This
information was originally contained in two tape files in the CICIS—Chemical
Production Information Tape, which is documented in OTIS Computer Products
Data Sheet, Accession No. PB80-155153, EPA Report No. EPA/DE-80/005.
The TSCAPP data base contains two separate sets of entries: one of production
information concerning the production of a single substance in a plant;
another set of entries containing information about plants. These two sets of
entries are accessed by different cattnands, but can be combined in various
ways for display. For example, searches performed by CAS Registry Number will
allow assessment of the total annual production of a. given conpound, and the
manufacturing sites can be identified.

SECTION 8
DATA TABLES FOR CHEMICALS
Detailed data tables showing the basis for the proposed KQs for the chemicals
following the SCP strategy as described in Section 2 are presented in Table
8-1. This list of chemicals are those hazardous substances designated under
the CWA Sections 311(b)(4) and 307 (a) and the hazardous air pollutants
designated under CAA Section 112. (Substances designated under RCRA Section
3001 appear later in Section 9.) The tables include the data on aquatic
toxicity, mammalian toxicity, chronic toxicity, ignitability, and reactivity
upon Which the choice of the proposed RQ is based. As discussed elsewhere in
this report, many substances remain to be assessed for chronic toxicity or
carcinogenicity by the BCAO or CAG, respectively, and these substances are
appropriately flagged "CHRON TEA" or "CARC TEA" in the column titled "Chronic
Toxicity/Carcinogen-Note 4." In those cases where the chronic toxicity
assessments are not yet available, RQs have been suggested based on data using
other factors. Hcwever, no RQ is proposed in Table 2-1 (or the NPRM) for
those substances that must still be assessed. No RQs have yet been assessed
based on carcinogenicity.
All notes listed in the table are located at the end of this section, and all
abbreviations used are discussed there in some length. For those not
concerned with the complete development of the data in Table 8-1, the most
common abbreviations are as follows:

NOTES FOR COMPREHENSIVE HAZARDOUS SUBSTANCES LIST
PART I - CHEMICALS
NOTE 1: The materials which appear on this comprehensive hazardous substances
list (Table 8-1) are those chemicals Which comprise Part I of the CERdA
101.14 list. At the present time these include the following: 297
chemicals designated under Section 311(b) (4) of the Clean Water Act
(40CFR117); 126 specfic chemicals (priority pollutants) designated under
Section 307(a) of the Clean Water Act; and finally 6 chemicals (all of
which are duplicates already listed under Section 307) designated under
Section 112 of the Clean Air Act (proposed 40CFR61). No entries have been
listed under the Toxic Substances Control Act (TSCA).
NOTE 2: Aquatic Toxicity, unless specifically noted otherwise, is given as the
TLm96 (The 96-Hour Median Threshold Limit) for aquatic species. TL.96 is
that concentration of the material dissolved in water, in parts per
million (ppm) or milligrams/liter (mg/1) (which is equivalent) that will
kill 50% of the test organism population in 96 hours. Each TL96 entry is
followed by a letter indicating the reportable quantity category to which
it corresponds, on the following scale:
TL 96 RQ (Pounds)
<0.1 X (1)
0.1-1 A (10)
1-10 B (100)
10-100 C (1000)
100-500 D (5000)
Note that TL and LC5Q (that is, Lethal Concentration which will kill 50%
of the tes? population) are identical, as long as the time period is the
same.
Aquatic toxicity data are taken from the following sources:
A. The reportable quantities assigned under Section 311 of the Clean
Water Act, as given in 40CFR117.3 (44FR10270-10283, February 16,
1979). The detailed listing of aquatic toxicities that form the basis
for these assignments is found in report No. EPA440/9-75/009,
"Supplement to Document Development: Hazardous Substances
Regulations, Section 311 of the Federal Water Pollution Control Act as
Amended 1972," November 1975 (PB 258514).
B. "The Registry of the Toxic Effects of Chemical Substances," RTECS,
accessed as a machine-searchable data base via the EPA/NIH Chemical
Information System (CIS). Latest update of this data base was January
1981. RTECS is available in hardcopy, the latest being DHHS (NIOSH)

NOTE 3: Three types of mammalian toxicity are entered in this column,
depending on the route of administration: oral, dermal (skin absorption)
or inhalation. The details of the entries are as follows:
A. Oral Toxicity; Unless otherwise identified, entries are those showing
the acute oral LD^ (Dose Lethal to 50% of the test animal population)
in milligrams pernoLlogram of body weight (rag/kg). Test species are
coded using the RTECS convention, as follows:
HMN = human
RAT = rat
MUS = mouse
GPG = guinea pig
DOG = dog
RBT = rabbit
8-38
-------
Thus the entry "Rat-orl:60" indicates an oral LD_ of 60 mg/kg for
rats.
50
B. Dermal Toxicity; These entries are indicated by the abbreviation
"skn" immediately following the species code, and are again given as
the acute LDcn (Dose Lethal to 50% of the test animal population) in
milligrams per kilogram of body weight (mg/kg). Test species are
coded the same as given under Oral Toxicity, above. Thus the entry
"Rat-skn:60" indicates dermal LD^ of 60 mg/kg for rats.
C. Inhalation Toxicity; These entries are indicated by the abbreviation
"ihl" immediately following the species code. Data are presented in
terms of the LC^ (Concentration in air Lethal to 50% of the test
animal population) in parts per million (ppm). The exposure time is
also given (H = hours, M = minutes), when available. Test species are
coded the same as given under Oral Toxicity, above. Thus the entry
"Rat-ihl:60/4H" indicates an inhalation LC^^ of 60 ppm for 4 hours for
rats.
-50
D. Lew Lethal Dose (or Concentration): These are shown by the term "lo"
immediately following the data entry. This means that the entry is
derived from UV_ or LC, data given in the literature. LDj-j and I£lo
are the lowest doses or concentrations known to have had letnal effect
on the test species. Thus the entry Rat-ihl:60/4H (lo) indicates an
inhalation LC. of 60 ppm for 4 hours for rats.
(Note: Human LC and IA_ data are not used, since they generally
represent isolated accidental poisoning incidents. Toxicity data,
unless specifically noted otherwise, have been obtained from the
"Itegistry of the Toxic Effects of Chemical Substances." (See Note 2B,
above.)
Each toxicity entry is followed by a letter indicating the reportable
quantity to which it corresponds, on the following scales:

NOTE 4: Entries in this column are several and include the following:
A. The results of evaluations of chronic toxicity effects carried out by
the EPA Environmental Criteria and Assessment Office (ECAO). For
chronic toxicity, the entries are given as a numerical score, followed
by an equivalent RQ designation, as follows:
Chronic Toxicity Score RQ(pounds)
81 to 100 X (1)
41 to 80 A (10)
21 to 40 B (100)
6 to 20 C (1000)
1 to 5 D (5000)
The scores are based on a combination of values assigned to minimum
effective doses and severity of the toxic effects, as described in
more detail elsewhere in this report.
B. The abbreviation "CHRON TBA" is used to identify those items that
remain to be assessed for chronic toxicity by the ECAO. Entries
flagged with "CHRON TBA" are materials that have previously been
identified by the EPA as having an appreciable chronic or subacute
effect, as described in any of the following documents:
o "Background Document. Resource Conservation and Recovery Act.
Subtitle C - Identification and Listing of Hazardous Waste,
Appendix A - Health and Environmental Effect Profiles. October
30, 1980. U.S. EPA, Office of Solid Waste."
o "EPA/440/9-75/009. Supplement to Development Document: Hazardous
Substances Regulations, Section 311 of the Federal Water Pollution
Control Act as Amended 1972. U.S. EPA. November 1975."
o "EPA 440/5-80-015 through -079. Ambient Water Quality Critera
Documents (64 documents). U.S. EPA, Office of Water Regulations
and Standards Criteria and Standards Division. October 1980."
C. The entry "CHRON*" indicates that the material is known to have a
chronic effect, but since its RQ has already been set at the 1 Ib
level on the basis of some other criterion, no further evaluation has
been carried out.
D. The abbreviation "CARC TBA" is used to identify those hazardous
substances that will be assessed for carcinogenicity by the EPA
Carcinogen Assessment Group (GAG), and therefore the suggested RQ of
the material may be subject to further adjustment. Entries identified
with a "CARC TBA" are materials that have been identified elsewhere as
potential carcinogens in lists published by the following sources:
8-40
-------
1. U.S. Department of Health and Human Services, National Toxicology
Program, U.S. Public Health Services.
o First Annual Report on Carcinogens, July 1980 - lists 26
substances or classes of substances.
o Second Annual Report on Carcinogens, December 1981 - lists 88
substances or classes of substances.
2. International Agency for Research on Cancer, Summary of Monographs
1-2, September 1979 - lists 142 substances.
E. The entry "CARC*" indicates that the material is known to be a
carcinogen, but since its RQ has already been set at the 1-lb level on
the basis of some other criterion, no further evaluation will be
carried cut.
NOTE 5: I, C, R stand for Ignitability, Corrosivity, and Reactivity.
A. Ignitabilityi This is judged on combinations of flash point and
boiling point. These are entered in the column as F = flash point,
and B = boiling point, with the value immediately following in degrees
Fahrenheit. Materials that are capable of starting fires without an
external source of ignition are considered to be the most hazardous,
and are coded as follows:
PYR = Pyrophoric
SPONT. IGN = Capable of spontaneous ignition
STRONG COCLD. = Strong oxidizer, may cause other materials to ignite,
and sustain their combustion.
B
. Gorrosivity; No ranking scale has yet been developed for corrosivity.
C. Reactivity; Reactivity refers to either a material's reaction with
water, compared with certain reference materials (see scale given
below) or to its ability to undergo self-reaction, with explosion
being the worst case. Certain other types of reactivity, such as the
ability to liberate toxic gases, are discussed as individual cases in
separate notes.
Each Ignitability or Reactivity entry is followed by a letter indicating
the reportable quantity category to which it corresponds, based on the
following truncated scales:

NOTE 6: Entries under this column show the value in pounds that was assigned
as a reportable quantity under Section 311 of the Clean Vfeter Act
(40CFR117.3, 44FR10279-10283, February 16, 1979).
NOTE 7: Entries in this column are the lowest reportable quantities derived
fron the individual rankings shown under the Aquatic Toxicity, Mammalian
Toxicity, Chronic Toxicity, and/or I/C/R columns.
NOTE 8: Entries in this column show
suggested, ceded as follows:
the basis on which an RQ has been
311 - Aquatic toxicity, as assigned under Section 311 of the
Clean Water Act.
AQTX - Aquatic toxicity, other than a 311 assignment.
T(orl) - Oral mammalian toxicity
T(ihl) - Inhalation mammalian toxicity
T(skn) - Skin (dermal) mammalian toxicity
CTX - Chronic Toxicity
I - Ignitablity
R - Reactivity
CS - This entry indicates that the assignment of an RQ has been
made on the basis of chemical similarity, in the absence
of data for the primary criteria.
Max - This entry indicates that the rating factors all exceed
the upper limit of the rating scales, and that the
assignment of a 5000-lb RQ has been made on the basis
of this being the largest value possible to assign.
8-42
-------
NOTE 9: It might be prudent to establish a lower RQ for this hazardous
substance on the basis of it being a member of the polynuclear aromatic
hydrocarbon class. Many PNA's are known or suspected carcinogens. While
no definitive proof exists that all PNA's are carcinogens, experimental
evidence suggests that these materials do cause formation of tumors and
neoplasms. The materials benzo(k)fluoranthene and benzo( j)fluoranthene,
for example, have been shown to cause cancer, however they are classified
as suspect because the data were obtained from only one species. The
materials benzo(ghi)perylene, fluoranthene and pyrene have been identified
as promoters or co-carcinogens. ("Biorefractories in Water, Carcinogens,
Mutagens, Promoters" U.S. Department of Health and Human Services, Public
Health Services, National Institute of Health, First Report, February
1980.) Carcinogenicity is currently under consideration for use as a
primary ranking factor.
NOTE 10: The aquatic toxicity data listed for this material were taken from
the 1980 Ambient Water Quality Criteria Documents.
NOTE 11: Evidence of the carcinogenicity of this material is currently being
assessed. The suggested RQ, therefore, may be subject to further
adjustment.
NOTE 12: No data have been found that permit the ranking of this material. A
working assignment of a 5000-lb RQ has been made on the basis of this
being the maximum value possible to assign. It may veil be that the
absence of data indicates that the material is not a hazard except as a
carcinogen, and that a much lower RQ will be assigned after the carcinogen
assessments are complete.
NOTE 13: Acetyl bromide reacts violently with water, forming toxic and
corrosive fumes of hydrogen bromide.
NOTE 14: Acetyl chloride reacts vigorously with water, evolving hydrogen
chloride fumes.
NOTE 15: The Registry of the Toxic Effects of Chemical Substances (RTECS)
gives an aquatic toxicity for acetyl chloride of 10-100 ppm, which would
place it in reportable quantity category C, rather than the reportable
quantity category D assigned under Section 311 of the Clean Water Act. No
attempt has been made to resolve this apparent discrepancy since the
suggested RQ for the material derives from other ranking factors.
NOTE 16: Polymerization may occur spontaneously in absence of oxygen or on
exposure to visible light or excessive heat, violently in the presence of
alkali. Pure acrylonitrile is subject to self-polymerization with rapid
pressure development. The commercial product requires an inhibitor.
NOTE 17: Evidence found in OBMTADS and/or "Water-Related Environmental Fate of
129 Priority Pollutants" (EPA-440/4-79-029a) indicates that this material.

-------
or a constituent of this material, is bioaccumulated to toxic levels in
the tissue of aquatic and marine organisms, and has the potential to
concentrate in the food chain.
NOTE 18: In the absence of specific data for the material listed, oral
toxicity data for the sodium salt is given in brackets.
NOTE 19: Ammonium bifluoride dissolves in water to form hydrofluoric acid. It
has been assigned a suggested RQ of 100 Ibs consistent with the suggested
RQ of 100 Ibs assigned to hydrofluoric acid, based on its chronic toxicity
assessment.
NOTE 20: Ammonium fluoride will dissolve in water to form hydrofluoric acid.
It has been assigned a suggested RQ of 100 Ibs based on its chronic
toxicity assessment.
NOTE 21: A maximum RQ level of 5000 Ibs has been assessed as a working value
for antimony metal until such time as its carcinogenicity and/or chronic
toxicity has been assessed. An RQ of 5000 Ibs is appropriate for massive
forms of the metal (ingots, rods, etc.). However, it is unlikely that the
Agency will require notification for releases of such massive forms, and
"massive" will be taken to mean that the diameter of the metal particles
is equal to or greater than 100 micrometers (0.004 inches). Such
particles wwll be excluded from chronic and carcinogenic assessments
because they are large enough not to be respirable. They are also large
enough not to react rapidly with air or water.
NOTE 22: Antimony pentachloride reacts vigorously with water to form hydrogen
chloride gas.
NOTE 23: Antimony trichloride reacts vigorously with water to form a strong
solution of hydrochloric acid.
NOTE 24: A maximum RQ level of 5000 Ibs has been assessed as a working value
for arsenic metal until such time as its carcinogenicity and/or chronic
toxicity has been assessed. An RQ of 5000 Ibs is appropriate for massive
forms of the metal (ingots, rods, etc.). Ifcwever, it is unlikely that the
Agency will require notification for releases of such massive forms, and
"massive" will be taken to mean that the diameter of the metal particles
is equal to or greater than 100 micrometers (0.004 inches). Such
particles wwll be excluded from chronic and carcinogenic assessments
because they are large enough not to be respirable. They are also large
enough not to react rapidly with air or water.
NOTE 25: Arsenic trichloride reacts vigorously with water to generate hydrogen
chloride.
NOTE 26: Benzoyl chloride will react energetically with water or steam with
production of heat, toxic and corrosive fumes.
8-44
-------
NOTE 27: Benzyl chloride, if unstabilized, readily undergoes a condensation
reaction with liberation of heat and hydrogen chloride in the presence of
copper, aluminvm, iron, zinc, magnesium, tin, and various other metals
that act as catalysts. If the reaction takes place in a container, there
is the possibility of violent rupture of the container.
NOTE 28: Beryllium chloride reacts vigorously with water with evolution of
heat. Forms beryllium oxide and hydrochloric acid solution.
NOTE 29: The different RQ levels assigned to the several phthalate esters may
arise from the fact that aquatic toxicity data is available for some of
them (e.g., dibutyl phthalate, RQ=100 Ibs, Basis:311(AQTX)) but is
unavailable for others (e.g., dioctyl phthalate, RQ=5000 Ibs, Basis:Max)
It might be appropriate to set all phthalate esters at an RQ level of B
(100 Ibs) on the basis of very close chemical similarity.
NOTE 30: Experimental evidence suggests that this material is either a
positive or potential teratogenic agent. A chronic toxicity assessment is
pending.
NOTE 31: A maximum RQ level of 5000 Ibs has been assessed as a working value
for cadmium metal until such time as its carcinogenicity and/or chronic
toxicity has been assessed. An RQ of 5000 Ibs is appropriate for massive
forms of the metal (ingots, rods, etc.). Hcwsver, it is unlikely that the
Agency will require notification for releases of such massive forms, and
"massive" will be taken to mean that the diameter of the metal particles
is equal to or greater than 100 micrometers (0.004 inches). Such
particles wwll be excluded from chronic and carcinogenic assessments
because they are large enough not to be respirable. They are also large
enough not to react rapidly with air or water.
NOTE 32: Calcium carbide produces acetylene gas on contact with water and will
generate sufficient heat on contact to ignite the acetylene. Based on
this fact, an RQ of 10 Ibs is suggested.
NOTE 33: The suggested RQ level of Category A (10 Ibs) is based on the fact
that this material is a strong oxidizer and can readily cause fires.
NOTE 34: Although no data could be found on the aquatic toxicity of this
material, it might be prudent to assign an RQ level of B (100 Ibs) on the
basis of the aquatic toxicity of other related chlorinated phenols.
NOTE 35: No data have been found that permit the ranking of this material.
ftjwever, an RQ level of category D (5000 Ibs) is suggested, based on the
oral toxicities of the related bis(chlorophenyl) ether (orl-gpg:1000
mg/kg) and diphenyl ether (orl-rat:3370 mg/kg).
NOTE 36: Chlorosulfonic acid is dangerously reactive in the presence of
moisture or water. It is a strong oxidizing agent and may cause ignition
by contact with combustible materials. Through its reaction with moisture
8-45
-------
in air or water it is broken down into hydrochloric and sulfuric acids.
An RQ level of 1000 Ibs is suggested.
NOTE 37: A maximum RQ level of 5000 Ibs has been assessed as a working value
for chromium metal until such time as its carcinogenicity and/or chronic
toxicity has been assessed. An RQ of 5000 Ibs is appropriate for massive
forms of the metal (ingots, rods, etc.). However, it is unlikely that the
Agency will require notification for releases of such massive forms, and
"massive" will be taken to mean that the diameter of the metal particles
is equal to or greater than 100 micrometers (0.004 inches). Such
particles wwll be excluded from chronic and carcinogenic assessments
because they are large enough not to be respirable. They are also large
enough not to react rapidly with air or water.
NOTE 38: An RQ category of C(1000 Ibs) is recommended for copper metal on the
basis of its chronic toxicity. This RQ is not meant to apply to massive
forms of the metal (ingots, rods, etc.). It is unlikely that the Agency
will require notification for releases of such massive forms, and
"massive" will be taken to mean that the diameter of the metal particles
is equal to or greater than 100 micrometers (0.004 inches). Such
particles are considered to be excluded from the chronic and carcinogenic
assessments because they are large enough not to be respirable. They are
also large enough not to react rapidly with air or water.
NOTE 39: The range of flash points (F) and boiling points (B) shown in the ICR
column derives from the three different Cresol isotners, ortho-, meta-, and
para-.
NOTE 40: In addition to its flammability, this material may polymerize at
elevated temperatures. If the polymerization takes place in a container,
there is possibility of violent rupture of the container. It is readily
converted by oxygen to hazardous peroxides and acids.
NOTE 41: Crotonaldehyde has been identified under two different CAS Registry
numbers, 4170-30-3 and 123-73-9, the latter referring to the trans-isomer.
The mammalian toxicity data listed are for the trans- isomer.
NOTE 42: All cyanides assigned reportable quantities under Section 311 of the
Clean Water Act (40CFR117.3, 44FR10279-10283, February 16, 1979) were
placed at RQ level A (10 Ibs) on the basis of the aquatic toxicity of the
cyanide ion. The same practice is continued here, with aquatic toxicity
values and 311 ratings placed in brackets to indicate that they were not
actually part of the aforementioned regulation, but derive their suggested
RQ from it nonetheless.
NOTE 43: The CAS Registry number listed for the generic class of Cyanides
refers to the cyanide ion only.
NOTE 44: This material requires an inhibitor to prevent polymerization.
8-46
-------
NOTE 45: The data listed are for 1,2-Dichloropropane.
NOTE 46: Although flash point data are not specifically listed for the
dichloropropane - dichloropropene mixture, it is reasonable to assume that
this mixture will have a similar ignitability rating as the individual
components.
NOTE 47: The suggested RQ for all isomers is based on the aquatic toxicity
rating of 1,3-Dichloropropene.
NOTE 48: The RQ level, Category B (100 Ibs), suggested for this material is
based on aquatic toxicity data found in OHMI&DS. 1.2 ppm of the material
is indicated as lethal to goldfish in 30 minutes, and a much lower
survival is noted for brine shrimp at the 10 ppm level.
NOTE 49: The data listed are for 2,4-Dinitrophenol (51-28-5). An RQ of 1000
Ibs was established for dinitrophenols under Section 311 of the Clean
Water Act (40CRF117.3, 44FR10279-10283, February 16, 1979). However,
there were no specific isomers identified in making that assigrment. An
RQ of 100 Ibs is suggested for 2,4-Dinitrophenol on the basis of an
aquatic toxicity lower than that used to make the assignments under
Section 311.
NOTE 50: The suggested RQ is based on the RQ established for Endosulfan itself
under Section 311 of the Clean Water Act.
NOTE 51: The suggested RQ is based on the RQ established for Endrin itself
under Section 311 of the Clean Water Act.
NOTE 52: This material is the same as 1,2-Dichloroethane.
NOTE 53: An RQ of 1 Ib is suggested for this material based on the 1 Ib RQ
assigned to Heptachlor under Section 311 of the Clean Water Act.
NOTE 54: An RQ of 1 Ib was established for the gamna isomer of hexachloro-
cyclohexane, commonly known as Lindane, under Section 311 of the Clean
Water Act. An RQ of 1 Ib is suggested for all isomers of
Hexachlorocyclohexane, based on similar chemical structures, since
detailed data are not available in all cases.
NOTE 55: This material is the same as Lindane (58-89-9).
NOTE 56: In addition to its high flammability, isoprene requires an inhibitor
to prevent self-polymerization. At elevated temperatures, such as in fire
conditions, polymerization may take place. If the polymerization takes
place in a container there is a possibility of violent rupture of the
container.
NOTE 57: A maximum RQ level of 5000 Ibs has been assessed as a working value
for lead metal until such time as its carcinogenicity and/or chronic
8-47
-------
toxicity has been assessed. An RQ of 5000 Ibs is appropriate for massive
forms of the metal (ingots, rods, etc.). However, it is unlikely that the
Agency will require notification for releases of such massive forms, and
"massive" will be taken to mean that the diameter of the metal particles
is equal to or greater than 100 micrometers (0.004 inches). Such
particles wwll be excluded from chronic and carcinogenic assessments
because they are large enough not to be respirable. They are also large
enough not to react rapidly with air or water.
NOTE 58: The I£50 - 96 hour aquatic toxicity range listed in OHMEADS for this
material is 0.64-1.4 ppm for rainbow trout. Using this data, an RQ level
of Category A (10 Ibs) would apply, rather than the 100 Ib RQ assigned
under Section 311 of the Clean Water Act.
NOTE 59: According to the OHMTADS file, mercury compounds have been shown to
be teratogenic. Chronic toxicity assessments are pending.
NOTE 60: long-term exposure to mercury vapor is known to induce a degenerative
disease (mercurialism, the "Hatter's Disease") in humans.
NOTE 61: Inhalation of high concentrations of methylchloride causes serious
central nervous system damage, lingering illness, and sonetimes death.
Persons may unknowingly be exposed to considerable concentrations because
it has no detectable odor.
NOTE 62: Polymerization of this material may occur upon exposure to heat,
oxidizing agents and ultraviolet light.
NOTE 63: There is a wide range of aquatic toxicities reported for napthalene
in OHMEADS, ranging down to 1 ppm for certain species and conditions.
Similarly, RTECS reports an aquatic toxicity for napthalene of 1-10 ppm.
On this basis, a lower RQ has been suggested than that established under
Section 311 of the Clean Water Act.
NOTE 64: An RQ level of 100 Ibs is suggested at the present time for nickel
metal, until its chronic toxicity and carcinogenicity have been fully
assessed. The 100 Ib RQ is based on mammalian toxicity. This RQ is not
meant to apply to massive forms of the metal (ingots, rods, etc.). It is
unlikely that the Agency will require notification for releases of such
massive forms, and "massive" will be taken to mean that the diameter of
the metal particles is equal to or greater than 100 micrometers (0.004
inches). Such particles are considered to be excluded from the chronic
and carcinogenic assessments because they are large enough not to be
respirable. They are also large enough not to react rapidly with air or
water.
NOTE 65: The inhalation toxicity data listed is for red fuming nitric acid.
NOTE 66: An RQ of 1000 Ibs was established for nitrophenol under Section 311
of the Clean Water Act, using a single aquatic toxicity data point of 46.3
8-48
-------
ppm. However, there were no specific iscmers identified in making that
assignment. A lower RQ of 100 Ibs is suggested for all isomers of
nitrophenol on the basis of similar chemical structure to 4-Nitrophenol,
which has an aquatic toxicity lower than that used to make the assignment
for nitrophenol under Section 311.
NOTE 67: Phosphorus oxychloride reacts violently with water and moisture to
yield hydrogen chloride.
NOTE 68: Phosphorus sulfide reacts with water to liberate hydrogen sulfide, as
indicated by the symbols H.S in the I/C/R columns of the table. The RQ
suggested for H-S is also 100 Ibs.
NOTE 69: Phosphorous trichloride will react violently when brought into
contact with water and may produce flashes of fire. Hydrochloric and
phosphorous acids are generated as products of the reaction with water.
NOTE 70: An RQ level of Category X (1 Ib) is suggested for each of the
individual Aroclor compounds, based on the aquatic toxicity listed for the
broad class of PCB's.
NOTE 71: This material is not combustible but the solid form in contact with
moisture or water may generate sufficient heat to ignite combustible
materials. Contact with some metals can generate flammable hydrogen gas.
NOTE 72: This material may polymerize with evolution of heat when in contact
with highly active catalytic surfaces such as anhydrous chlorides of iron,
tin, and aluminum, peroxides of iron and aluminum, and alkali metal
hydroxides. If the polymerization takes place in a container there is
possibility of violent rupture of the container.
NOTE 73: Pyrethrins were designated under Section 311 of the Clean Water Act
with no specific reference to eigher Pyrethrin I (CAS No. 121-21-1) or
Pyretnrin II (CAS No. 121-29-9). Both CAS Registry numbers are given
here.*
NOTE 74: Since SeO- immediately hydrates to ^SeO-j in water, their toxicities
are, for all practical purposes, equivalent.
NOTE 75: A maximum RQ level of 1000 Ibs is suggested at the present time for
silver metal, based on its chronic toxicity ranking. This RQ is not meant
to apply to massive forms of the metal (ingots, rods, etc.). It is
unlikely that the Agency will require notification for releases of such
massive forms, and "massive" will be taken to mean that the diameter of
the metal particles is equal to or greater than 100 micrometers (0.004
inches) . Such particles are considered to be excluded from the chronic
and carcinogenic assessments because they are large enough not to be
respirable. They are also large enough not to react rapidly with air or
water.

-------
NOTE 76: Sodium is extremely dangerous in contact with moisture or water,
releasing hydrogen with sufficient heat to cause ignition or explosion.
It ignites spontaneously in air or oxygen. It burns violently accompanied
by explosions which cause spattering of the material.
NOTE 77: Sodium bifluoride reacts with water liberating heat and forming
hydrofluoric acid. It has been assigned a suggested RQ of 100 Ibs
consistent with the suggested RQ of 100 Ibs assigned to hydrofluoric acid/
based on its reactivity with water.
NOTE 78: This material is not combustible but the solid form in contact with
moisture or water may generate sufficient heat to ignite combustible
materials. Contact with some metals can generate hydrogen gas.
NOTE 79: The aquatic toxicity data and the suggested RQ (10 Ibs) apply to both
strychnine and its salts. Strychnine is a common name for this material.
NOTE 80: Polymerization may occur if heated above 150°F. Can cause rupture of
container. Metal salts, peroxides, and strong acids may also cause
polymerization.
NOTE 81: Sulfur monochloride reacts violently with water to produce heat and
hydrogen chloride fumes. The resulting solution is strongly acidic.
NOTE 82: The common name for this material is carbon tetrachloride.
NOTE 83: An RQ level of 1000 Ibs is suggested at the present time for thallium
metal, based on its mammalian toxicity ranking until assessment of its
chronic toxicity has been completed. This RQ is not meant to apply to
massive forms of the metal (ingots, rods, etc.). It is unlikely that the
Agency will require notification for releases of such massive forms, and
"massive" will be taken to mean that the diameter of the metal particles
is equal to or greater than 100 micrometers (0.004 inches). Such
particles are considered to be excluded from the chronic and carcinogenic
assessments because they are large enough not to be respirable. They are
also large enough not to react rapidly with air or water.
NOTE 84: Vinyl chloride polymerizes in presence of air, sunlight, or heat
unless stabilized by inhibitors.
NOTE 85: This material is also known as 1,1-Dichloroethylene.
NOTE 86: The range of flash points (F) and boiling points (B) shown in the ICR
column derives from the three different Xylene isctners, ortho-, meta-, and
para-.
NOTE 87: A maximum RQ level of 5000 Ibs has been assessed as a working value
for zinc metal until such time as its carcinogenicity and/or chronic
toxicity has been assessed. An RQ of 5000 Ibs is appropriate for massive
forms of the metal (ingots, rods, etc.). Hcwever, it is unlikely that the
8-50
-------
Agency will require notification for releases of such massive forms, and
"massive" will be taken to mean that the diameter of the metal particles
is equal to or greater than 100 micrometers (0.004 inches). Such
particles wwll be excluded fron chronic and carcinogenic assessments
because they are large enough not to be respirable. They are also large
enough not to react rapidly with air or water.
NOTE 88: A metal phosphide will react with water to liberate phosphine as
indicated by the symbols FH_ in the ICR column of the table. The
suggested reportable quantity or this material is thus suggested at a
value of 100 Ibs.
NOTE 89: This material will react vigorously with water, liberating heat, to
form hydrogen chloride, and will fume in moist air. An RQ level of
Category D (5000 Ibs) is suggested on this basis.
NOTE 90: The suggested RQ takes into consideration one or more of the natural
dissipation processes of biodegradation, hydrolysis or photolysis. More
specifically, the lowest RQ suggested by any of the primary ranking
factors has been adjusted upward one level.

SECTION 9
DATA TABLES FOR HAZARDOUS WASTES
Detailed data tables showing the basis for the proposed FQs for the hazardous
wastes following the SCP strategy as described in Section 2 are presented in
Tables 9-1 and 9-2. These lists are the hazardous substances designated under
RCRA Section 3001. The substances are cotmonly called the "P," "U," "F," and
"K" wastes, referring to the initial letter used to identify them by hazardous
waste number in 40 CFR Part 261. Data are given in Table 9-1 for the P- and U-
wastes and Table 9-2 for the F- and K- waste streams. The tables include the
data on ignitability, reactivity, aquatic toxicity, mamnalian toxicity, and
chronic toxicity, upon which the choice of the proposed RQ is based. As
discussed elsewhere in this report, many substances remain to be assessed for
chronic toxicity or carcinogenicity by the ECAO or GAG, respectively, and these
substances are appropriately flagged "CHRON TBA" or "CARC TEA" in the column
titled "Chronic Toxicity/Carcinogen-Nbte 5." In those cases where the chronic
toxicity assessments are not yet available, RQs have been suggested based on
data using other factors. No RQs have yet been assessed based on
carcinogenicity.
All notes listed in the table are located at the end of this section, and all
abbreviations used are discussed there in some length. For those not concerned
with the complete development of the data in Table 9-1, the most cannon
abbreviations are as follows:
(X), (A), (B), (C), (D) - RQ Categories 1, 10, 100, 1000, and 5000
Ibs, respectively
CARC TBA - To be assessed for carcinogenicity
CHRON TBA - To be assessed for chronic toxicity
9-1
-------
GARC* - Known carcinogen, but RQ already as low as possible (1 Ib) on
some other basis
CHRQN* - Known chronic toxicant, but RQ already as low as possible (1
Ib) on some other basis
F - Flash point
B - Boiling point
R - Reactivity
311 - The RQ was established under the regulations from CWA Section
311
AQTX - Aquatic toxicity
CTX - Chronic toxicity
BHP - Biodegradation, hydrolysis, and photolysis
ICR - Ignitability, corrosivity, and reactivity
CS - The RQ was assigned on the basis of chemical similarity to
another substance, in the absence of data for the primary criteria.
Max - Maximum possible RQ assignment

NOTES FOR TABLE 9-1, COMPREHENSIVE HAZARDOUS SUBSTANCES LIST
PART II - HAZARDOUS WASTES
A - Acute Hazardous Wastes
B - Toxic Wastes
NOTE 1: The abbreviation No. (ALT.) stands for NUMBER (ALTERNATE). Each line
item is numbered consecutively, with an alternate number immediately
following in parentheses. With a few exceptions, each compound on the
Acute Hazardous Wastes List, A (P List) and Toxic Wastes List, B (U List)
is listed a second time by an alternate name. The entries in this column
serve as a cross- index of those alternates. Thus, the entry 8 (383) for
U002, Acetone, refers the reader to the synonym U002, 2-Propanone where,
conversely, the entry 383 (8) refers back to U002, Acetone. The P list
and U list are numbered separately.
NOTE 2: The listing criteria are I, C, R, and T, standing for Ignitability,
Corrosivity, Reactivity, and Extraction Procedure Toxicity, respectively.
These represent the reasons why a material was listed as a hazardous waste
in the first place, and have been explained in detail in the RCRA
(Resource Conservation and Recovery Act) regulations, 40261.10 through
40261.24 (45FR33121-33122, May 19, 1980).
NOTE 3: Aquatic Toxicity, unless specifically noted otherwise, is given as the
TL 96 (The 96-Hour Median Threshold Limit) for aquatic species. TL 96 is
that concentration of the material dissolved in water, in parts per
million (ppm) or milligrams/liter (mg/1) (which is equivalent) that will
kill 50% of the test organism population in 96 hours. Each TLm96 entry is
followed by a letter indicating the reportable quantity to which it
corresponds, on the following scale:
RQ (Pounds)
Less than (5.1 X (1)
0.1-1 A (10)
1-10 B (100)
10-100 C (1000)
100-500 D (5000)
Note that TL and LC5Q (that is, Lethal Concentration which will kill 50%
of the test population) are identical, as long as the time period is the
same.
Aquatic toxicity data are taken from the following sources:
A. The reportable quantities assigned under Section 311 of the Clean
Water Act, as given in 40CFR117.3 (44FR10279-10283, February 16,
1979). The detailed listing of aquatic toxicities that form the basis
9-48
-------
for these assignments is found in Report No. EPA 1440/9-75/009,
"Supplement to Development Document: Hazardous Substances
Regulations, Section 311 of the Federal Water Pollution Control Act as
Amended 1972", November 1975 (PB 258514).
B. "The Registry of the Toxic Effects of Chemical Substances", FTECS,
accessed as a machine-searchable data base via the EPA/NIH Chemical
Information System (CIS). Latest update of this data base was January
1981. RTECS is available in hardcopy, the latest being DHHS (NIOSH)
Publication No. 8-111, "1979 Registry of the Toxic Effects of Chemical
Substances", Volumes 1 and 2, U.S. Department of Health and Human
Services, Public Health Service, Center for Disease Control, National
Institute for Occupational Safety and Health, September 1980.
RTECS draws its aquatic toxicity data from "Water Quality
Characteristics of Hazardous Materials", by Dr. Roy Bahn, Jr. and Paul
Jensen, Texas ASM University, College Station, TX, 77843, 1974.
C. Publication 2-A, "Water Quality Criteria", Second Edition, Jack Edward
McKee and Harold v- Wblf (Editors). State of California, The
Resources Agency o$ California, State Water Quality Control Board,
1963. 1
D. "Handbook of Environmental Data on Organic Chemicals", Karel
Verschueren, Van Nostrand Reinhold Company, New York, NY, copyright
1977 by Litton Educational Publishing, Inc.
E. The "Oil and Hazardous Materials Technical Assistance Data Base"
(OHMTADS), accessed as a machine-searchable data base via the EPA/NIH
Chemical Information System (CIS).
F. The 1980 Ambient Water Quality Criteria Documents for 64 toxic
pollutants or pollutant categories, published pursuant to Section
304(a)(l) of the Clean Water Act (45FR231).
G. "Aquatic Toxicity Testing as Fundament for a Spill Prevention
Program", M. W. Curtis, C. M. Curran, and C.H. Ward, reported in the
Proceedings of the 1980 National Conference on Control of Hazardous
Materials Spills. (May 13-15, 1980, Louisville, Kentucky).
NOTE 4: Three types of mammalian toxicity are entered in this column,
depending on the route of administration: oral, dermal (skin absorption)
or inhalation. The details of the entries are as follows:
A. Oral Toxicity; Unless otherwise identified, entries are those showing
the acute oral LD5_ (Dose Lethal to 50% of the test animal population)
in milligrams per kilogram of body weight (rag/kg). Test species are
coded as follows:
9-49
-------
= human
RAT = rat
MUS = mouse
GPG = guinea pig
DOG = dog
RBT = rabbit
Thus the entry "RAT 60" indicates an oral LD50 of 60 rag/kg for rats.
B. Dermal Toxicity: These entries are indicated by the code "skin"
immediately following the species code, and are again given as the
acute LD50 (Dose Lethal to 50% of the test animal population) in
milligrams per kilogram of body weight (mg/kg). Test species are
coded the same as given under ORAL TOXICITY, above. Thus the entry
"RAT skin 60" indicates dermal LD5 of 60 mg/kg for rats.
C. Inhalation Toxicity: These entries are indicated by the abbreviation
"ihl" immediately following the species code. Data are presented in
terms of the LC,.Q (Concentration in air lethal to 50% of the test
animal population) in parts per million (ppm). The exposure time is
also given (H = hours, M = minutes), When available. Test species are
coded the same as given under Oral Toxicity, above. Thus the entry
"RAT ihl 60/4H" indicates an inhalation I£50 of 60 ppm for 4 hours for
rats.
D. Low Lethal Dose (or Concentration): These are shown by the term "lo"
immediately following the data entry. This means that the entry is
derived from LD or LC, data given in the literature. LD-iQ and LC,
are the lowest aSses or concentrations known to have had lethal effect
on the test species. Thus the entry RAT ihl 60/4H (lo) indicates an
inhalation LC, of 60 ppm for 4 hours for rats. (Note: Human !£..
and LD. data are not used, since they generally represent isolated
accidental poisoning incidents.) Toxicity data, unless specifically
noted otherwise, have been obtained from the "Registry of the Toxic
Effects of Chemical Substances". (See NOTE 3B above.)
Each toxicity entry is followed by a letter indicating the reportable
quantity category to which it corresponds, on the following scales:
Oral LD,.-. Dermal LD__ Inhalation LC_n
°£ l£ °£ 12 °£ lo RQ (Pounds)
<0.1 <0.04 <0.4 X (1)
0.1-1 0.04-0.4 0.4-4 A (10)
1-10 0.4 -4 4-40 B (100)
10-100 4-40 40-400 C (1000)
100-500 40-200 400-2000 D (5000)
9-50
-------
NOTE 5: Entries in this column are several and include the following:
A. The results of evaluations of chronic toxicity effects carried out by
the EPA Environmental Criteria and Assessment Office (ECAO). For
chronic toxicity, the entries are given as a numerical score, followed
by an equivalent RQ designation, as follows:
Chronic Toxicity Score RQ (pounds)
81 to 100 X (1)
41 to 80 A (10)
21 to 40 B (100)
6 to 20 C (1000)
1 to 5 D (5000)
The scores are based on a combination of values assigned to minimum
effective doses and severity of the toxic effects, as described in
more detail elsewhere in this report.
B. The abbreviation "CHRON TBA" is used to identify those items that are
still to be assessed for chronic toxicity by the ECAO. Entries
flagged with "CHRON TBA" are materials that have previously been
identified by the EPA as having an appreciable chronic or subacute
effect, as described in any of the following documents:
o "Background Document. Resource Conservation and Recovery Act.
Subtitle C - Identification and Listing of Hazardous Waste,
Appendix A - Health and Environmental Effect Profiles. October
30, 1980. U.S. EPA, Office of Solid Waste."
o "EPA/440/9-75/009. Supplement to Development Document: Hazardous
Substances Regulations, Section 311 of the Federal Water Pollution
Control Act as Amended 1972. U.S. EPA. November 1975."
o "EPA 440/5-80-015 through -079. Ambient Water Quality Critera
Documents (64 documents). U.S. EPA, Office of Water Regulations
and Standards Criteria and Standards Division. October 1980."
C. The entry "CHRON*" indicates that the material is known to have a
chronic effect, but since its RQ has already been set at the 1- or
10-lb level on the basis of some other criterion, no further
evaluation has been carried out.
D. The abbreviation "CARC TBA" is used to identify those hazardous
substances that will be assessed for carcinogenicity by the EPA
Carcinogen Assessment Group (GAG), and therefore the suggested RQ of
the material may be subject to further adjustment. Entries identified
with a "CARC TBA" are materials that have been identified elsewhere as
known human or animal carcinogens, from lists published by the
following sources:
9-51
-------
1. U.S. Department of Health and Human Services, National Toxicology
Program, U.S. Public Health Services.
o First Annual Report on Carcinogens, July 1980 - lists 26
substances or classes of substances.
o Second Annual Report on Carcinogens, December 1981 - lists 88
substances or classes of substances.
2. International Agency for Research on Cancer, Summary of Monographs
1-2, September 1979 - lists 142 substances.
E. The entry "CARC*" indicates that the material is known to be a
carcinogen, but since its RQ has already been set at the 1-lb level on
the basis of some other criterion, no further evaluation will be
carried out.
NOTE 6: I, C, R stand for Ignitability, Corrosivity, and Reactivity.
A. Ignitability: This is judged on combinations of flash point and
boiling point. These are entered in the column as F = flash point,
and B = boiling point, with the value immediately following in degrees
Fahrenheit. Materials that are capable of starting fires without an
external source of ignition are considered to be the most hazardous,
and are coded as follows:
PYR = Pyrophoric
SPONT. IGN. = Capable of spontaneous ignition
STRONG OXID. = Strong oxidizer, may cause other materials to
ignite, and sustain their combustion.
The entry "Solid" indicates that the material is solid at room
temperature, and not readily ignitable.
B. Corrosivity: No ranking scale has yet been developed for corrosivity.
C. Reactivity: Reactivity refers to either a material's reaction with
water, compared with certain reference materials (see scale given
below) or to its ability to undergo self-reaction, with explosion
being the worst case. Certain other types of reactivity, such as the
ability to liberate toxic gases, are discussed as individual cases in
separate notes.
9-52
-------
Each Ignitability or Reactivity entry is followed by a letter indicating
the reportable quantity category to which it corresponds, based on the
following scales:
Ignitability
Starts fires
F < 100
B < 100
F < 100
B < 100
F 100-140
REACTIVITY
With Water
(Reference Compound)
Inflames
Extreme reaction
(e.g., SO3)
High reaction
(e.g., oleum)
Moderate reaction
(e.g., NH3)
Self-Reaction
Explosive
May polymerize;

May polymerize if
contaminated. No
stabilizer required.
Some chance of poly-
merization with small
heat release.
RQ (Pounds)
A (10)
B (100)
C (1000)
D (5000)
Data for Ignitability and Reactivity ratings were taken frcm "Fire
Protection Guide on Hazardous Materials", 7th Edition, National Fire
Protection Association, Boston, MA, 1978.
NOTE 7: Entries under this column show the value in pounds that was assigned
as a reportable quantity under Section 311 of the Clean Water Act
(40CFR117.3, 44FR10279-10283, February 16, 1979).
NOTE 8: Entries in this column are the lowest reportable quantities derived
frcm the individual rankings shown under the Aquatic Toxicity, Mammalian
Toxicity, Chronic Toxicity, and/or I/C/R columns.
NOTE 9: Entries in this column show the basis on which an RQ has been
suggested, coded as follows:
311 - Aquatic toxicity, as assigned under Section 311 of the
Clean Water Act.
AQTX - Aquatic toxicity, other than a 311 assignment
T(orl) - Oral mammalian toxicity
T(ihl) - Inhalation mammalian toxicity
T(skn) - Skin (dermal) mammalian toxicity
CTX - Chronic Toxicity
9-53
-------
I - Ignitability
R - Reactivity
CS - This entry indicates that the assignment of an RQ has
been made on the basis of chemical similarity, in the
absence of data for the primary criteria.
Max - This entry indicates that the rating factors all exceed
the upper limit of the rating scales, and that the
assignment of a 5000-lb RQ has been made on the basis of
this being the largest value possible to assign.
Note 10: Evidence found in CfMTADS and/or "Water-Related Environmental
Fate of 129 Priority Pollutants" (EPA-*440/4-79-029a) indicates that
this material, or a constituent of this material, is bioaccumulated to
toxic levels in the tissue of aquatic and marine organisms, and has
the potential to concentrate in the food chain.
NOTE 11: A metal phosphide will react with water to liberate phosphine, as
indicated by the symbol PH., in the I/C/R column of the table. The
suggested reportable quantity of this material is thus set equal to
that suggested for phosphine (PO96), at a value of 100 Ibs.
NOTE 12: There are two arsenic acids, one identified by the Chemical
Abstracts Service Registry Number (CAS No.) 7778-39-4, and having
synonyms as arsenic acid (H^AsCO, arsenic acid solution, arsenic acid
liquid, and orthoarsenic acid. The other, with CAS No. 1327-52-2, has
the synonyms arsenic acid liquid and arsenic anhydride. Data on the
latter may be found in OFMTADS, while the toxicity of the former may
be found in RTECS.
NOTE 13: Evidence of the carcinogenicity of this material is currently
being assessed. The suggested RQ, therefore, may be subject to
further adjustment.
NOTE 14: Degradation of this substance could lead to the formation of
trivalent inorganic arsenic compounds, which have been identified as
carcinogens in the "First Annual Report on Carcinogens".
NOTE 15: No specific data was found for diethylarsine. Pfowever, the alkyl
arsines, as a class, are pyrophoric, and diethyl arsine has been
placed at a suggested RQ level of A (10 Ibs) on this basis. (See also
Note 14.)
NOTE 16: Benzyl chloride, if unstabilized, readily undergoes a
condensation reaction with liberation of heat and hydrogen chloride in
the presence of copper, aluminum, iron, zinc, magnesium, tin, and
various other metals that act as catalysts. If the reaction takes
place in a container, there is the possibility of violent rupture of
9-54
-------
the container.
NOTE 17: The aquatic toxicity data listed for this material were taken
from the 1980 Ambient Water Quality Criteria Documents.
NOTE 18: All cyanides assigned reportable quantities under Section 311 of
the Clean Water Act (40CFR117.3, 44FR10279-10283, February 16, 1979)
were placed at RQ level A (10 Ibs) on the basis of the aquatic
toxicity of the cyanide ion. The same practice is continued here.
NOTE 19: The CAS Registry number listed for the generic class of Cyanides
refers to the cyanide ion.
NOTE 20: Data are presented only for the cresol itself; however, the
suggested RQ also applies to the salts.
NOTE 21: AN RQ of 1000 Ibs was established for dinitrophenols under
Section 311 of the Clean Water Act (40CFR117.3, 44FR10279-10283,
February 16, 1979). ffcwever, there were no specific isomers
identified in making that assignment. An FQ of 100 Ibs is suggested
for 2,4-dinitrophehol on the basis of an aquatic toxicity lower than
that used to make the assignments under Section 311.
NOTE 22: The entry "Trichloromethylmercaptan" (pl!8) in 40 CFR 261.33 has
been taken to mean perchloromethylmercaptan, otherwise known as
trichloromethanesulf enyl chloride.
NOTE 23: Data are presented only for nicotine itself; however, the
suggested RQ also applies to the salts.
NOTE 24: Nitrogen (II) oxide (nitric oxide) is rapidly converted to
nitrogen (IV) oxide (nitrogen dioxide) upon exposure to air. The
inhalation toxicity shown (in brackets) is that of TV oxide.
NOTE 25: The suggested RQ level of Category A (10 Ibs) is based on the
fact that this material is a strong oxidizer and can readily cause
fires.
NOTE 26: The aquatic toxicity of this material is listed as less than 0.1
on the basis of its silver content; silver is extremely toxic to
aquatic organisms.
NOTE 27: An RQ level of B (100 Ibs) is suggested on the basis of
Reactivity, inasmuch as the mishandling of the material might result
in the release of hydrogen sulfide, which has been placed at the
100 Ib FQ level.
NOTE 28: The aquatic toxicity data and the suggested RQ (10 Ibs) apply to
both strychnine and its salts. Strychnine is a common name for this
material.
9-55
-------
NOTE 29: There is evidence that this or closely related compounds have
teratogenic effects. Chronic toxicity assessments are pending.
NOTE 30: This compound was identified as the selenite in the published
RCRA regulations (40CFR261.33, 45FR78542). "The Registry of the Toxic
Effects of Chemical Substances" also uses the name Thallium selenite,
but gives the formula TISe, which is that of Thallium Selenide. The
Structure and Nomenclature Search System (a component of the EPA/NIH
Chemical Information System (CIS) gives the name Thallium Selenide,
and the CAS No. shown here. It appears that selenide is the correct
term.
NOTE 31: Chloral rapidly hydrates upon ingest ion to form chloral hydrate.
The toxicity value shown is that of the hydrate.
NOTE 32: The Registry of the Tbxic Effects of Chemical Substances (RTECS)
gives an aquatic toxicity for acetyl chloride of 10-100 ppm, which
would place it in reportable quantity category C, rather than the
reportable quantity category D assigned under Section 311 of the Clean
Water Act. No attempt has been made to resolve this apparent
discrepancy, since the suggested RQ for the material derives from
other ranking factors.
NOTE 33 Acetyl chloride reacts vigorously with water, evolving hydrogen
chloride fumes.
NOTE 34: Polymerization may occur spontaneously in the absence of oxygen
or on exposure to visible light or excessive heat, violently in the
presence of alkali. Pure acrylonitrile is subject to
self-polymerization with rapid pressure development. The commercial
product requires an inhibitor.
NOTE 35: The different RQ levels assigned to the several phthalate esters
may arise from the fact that aquatic toxicity data is available for
some of them (e.g., dibutyl phthalate, RQ=100 Ibs, Basis:311 (AQTX))
but is unavailable for others (e.g., dioctyl phthalate, RQ=5000 Ibs,
Basis :Max). It might be appropriate to set all phthalate esters at an
RQ level of B (100 Ibs) on the basis of very close chemical
similarity.
NOTE 36: The RQ level, category B (100 Ibs) suggested for this material is
based on aquatic toxicity data found in OHMTADS. 1.2 ppm of the
material is indicated as lethal to goldfish in 30 minutes, and a much
lower survival is noted for brine shrimp at the 10 ppm level.
NOTE 37: An assignment of a 5000 Ib RQ has been made on the basis of this
being the maximum value possible to assign.
NOTE 38: It is highly likely that the intent in the RCRA regulations was
9-56
-------
to list Benzene,2,4-diisocyanatomethyl (CAS No. 584-84-9), which is
the same as Toluene diisocyanate (or Toluene,2,4-diisocyanate) and
which is also the more cannon item of ccranerce (U223). The compound
Benzene, 1,3-diisocyanatomethyl has a CAS Registry No. of 26471-62-5
and is chemically the same as Xylene diisocyanate.
NOTE 39 A working RQ value of 5000 Ibs has been assigned to this material,
pending its assessment for chronic toxicity affects. It would also be
possible, in the absence of any other data, to assign this material an
RQ based on its very close chemical similarity to hexachlorobenzene
and 1,2,4,5-tetrachlorobenzene.
NOTE 40: It might be prudent to establish a lower RQ for this hazardous
substance on the basis of it being a member of the polynuclear
aromatic hydrocarbon class. Many PNAs are known or suspected
carcinogens. While no definitive proof exists that all PNAs are
carcinogens, experimental evidence suggests that these materials do
cause formation of tumors and neoplasms. The materials
benzo(k)fluoranthene and benzo( j)fluoranthene, for example, have been
shown to cause cancer; however they are classified as suspect because
the data were obtained from only one species. The materials
benzo(ghi)perylene, fluoranthene and pyrene have been identified as
promoters or co-carcinogens. ("Biorefractories in Water, Carcinogens,
Mutagens, Promoters", U.S. Department of Health and Human Services,
Public Health Services, National Institute of Health, First Report,
February 1980.)
NOTE 41: In addition to its flammability, this material may polymerize at
elevated temperatures. If the polymerization takes place in a
container, there is possibility of violent rupture of the container.
It is readily converted by oxygen to hazardous peroxides and acids.
NOTE 42: Crotonaldehyde has been identified under two different CAS
Registry numbers, 4170-30-3 and 123-73-9, the latter referring to the
trans- isomer. The mammalian toxicity data listed are for the trans-
isomer.
NOTE 43: The RQ for this material is set at 5000 Ibs, based on oral
toxicity. Most other chlorinated phenols have much lower RQ values
(e.g., 2-chlorophenol and 2,4-dichlorophenol, working RQs set at 100
Ibs, pending chronic toxicity assessment) based in all cases on
aquatic toxicity data. It is possible that the comparatively high RQ
assigned in this case arises simply from the unavailability of aquatic
toxicity data. An RQ could be established for this substance on the
basis of its very close chemical similarity to the other
chlorophenols.
NOTE 44: Common name for this material is Epichlorohydrin.
NOTE 45: Coal tar cresote is identified by the Chemical Abstracts Service
9-57
-------
Registry Number (CAS No.) 8001-58-9, and data presented is for this
material. No data were found that would allow rating of beechwood
creosote, CAS No. 8021-39-4.
NOTE 46: The range of flash points (F) and boiling points (B) shown in the
ICR column derives frcm the three different Cresol isomers, ortho-,
meta-, and para-.
NOTE 47: Data are presented only for the free acid; however, the
suggested RQ also applies to salts and esters.
NOTE 48: This material is the same as Bis(2-chloroethyl)ether.
NOTE 49: Data on the aquatic toxicity for 2,6-Dichlorophenol may be found
in OHMEADS under the entry for 2,4-Dichlorophenol.
NOTE 50: Cannon name for this material is Hydrazobenzene.
NOTE 51: The oral toxicity value shown is for the sodium salt; however,
the suggested RQ applies to the free acid and esters as well.
NOTE 52: This material polymerizes in the presence of air, sunlight, or
heat unless stabilized by inhibitors.
NOTE 53: Inhalation toxicities are most caimonly measured over a 4-hour
period. In this case, the inhalation toxicity of 425 ppm was
determined in only 30 minutes. A 4-hour exposure would undoubtedly
bring that figure down to well under 400 ppm, corresponding to an RQ
category of C (1000 Ibs), and this RQ has accordingly been suggested.
NOTE 54: Long-term exposure to mercury vapor is taiown to induce a
degenerative disease (mercurialism, the "Hatters's Disease") in
humans.
NOTE 55: Inhalation of high concentrations of methyl chloride causes
serious central nervous system damage, lingering illness, and
sometimes death. Persons may unknowingly be exposed to considerable
concentrations because it has no detectable odor.
NOTE 56: This compound has been assigned an RQ value based on its very
close similarity to methyl bromide and brcmoform, which have suggested
RQ levels of C (1000 Ibs), and B (100 Ibs). The 1000 Ib level was
selected.
NOTE 57: Carmen name for this material is carbon tetrachloride.
NOTE 58: Polymerization of this material may occur upon exposure to heat,
oxidizing agents and ultraviolet light.
NOTE 59: There is a wide range of aquatic toxicities reported for
9-58
-------
naphthalene in CfM&DS, ranging down to 1 ppm for certain species and
conditions. Similarly, KTBCS reports an aquatic toxicity for
naphthalene of 1-10 ppm. On this basis, a lower RQ has been suggested
than that established under Section 311 of the Clean Water Act.
NOTE 60: HiQsphorus sulfide reacts with water to liberate hydrogen
sulfide, as indicated by the symbol H_S in the I/C/R columns of the
table. The RQ suggested for HjS is also 100 Ibs.
NOTE 61: The RCRA regulation (40CFR261.33, 45FR78544) lists selenious acid
and selenium dioxide under the same number (U204). Ifcwever, these are
two separate and distinct materials, and the Chemical Abstracts
Services Registry Number (CAS RN.) has been provided for each.
However, the distinction is of little consequence, since SeO-
immediately hydrates to H^SeCX, in water, so that their toxicities are,
for all practical purposes, equivalent. Brackets around entries for
these two compounds indicate where such equivalent data has been
assigned frcm one material to the other.
NOTE 62: Mishandling of this material could lead to the liberation of H_S,
and accordingly the suggested RQ is set at a level of B (100 Ibs).
NOTE 63: The range of flash points (F) and boiling points (B) shown in the
I/C/R column derives from thegthree different Xylene isomers, ortho-,
meta-, and para-.
NOTE 64: Tricloroacetaldehyde, chloral (hydrate) decomposes in alkaline
water to yield chloroform, an identified carcinogen. While evidence
directly implicating chloral as a carcinogen is scanty, and it is not
listed as such by either IARC or DEfflS in any of their publications, it
might be prudent to adjust its RQ on the basis of carcinogenicity
because it could be a precursor to a known carcinogen under many
conditions of release.
NOTE 65: The suggested RQ takes into consideration one or more of the
natural dissipation processes of biodegradation, hydrolysis, or
photolysis. More specifically, the lowest RQ suggested by any of the
primary ranking factors has been adjusted upward one level.

NOTES FOR TABIZ 9-2
COMPREHENSIVE HAZARDOUS SUBSTANCE LIST
PART II - HAZARDOUS WASTES
NON-SPECIFIC AND SPECIFIC WASTE STREAMS
NOTE 1: Each waste on these lists (the F and K lists) is followed by the
chemical name and parenthetically the CAS No. (Chemical Abstract Services
Registry Number) of its constituents. Where the constituents are
indefinite or generic in nature, and no CAS No. applies, the abbreviation
N.A. (Not Applicable) follows the entry. Constituents listed are either
those defined as part of the waste itself, or those given in the RCRA
(Resource Conservation and Recovery Act) regulation, 40CFR261, Appendix 7,
45FR4619-4620, January 16, 1981. The nomenclature is that used in these
two sources, and additional notes are provided to indicate where it
differs from that used elsewhere in this report.
NOTE 2: The listing criteria are I, C, R, and T, standing for Ignitability,
Corrosivity, Reactivity, and Extraction Procedure Toxicity, respectively.
This represents the reasons why a waste stream was listed as a hazardous
waste in the first place. They are explained in detail in the RCRA
(Resource Conservation and Recovery Act) regulations, 40CFR261.10 through
261.24 (45FR33121-33122, May 19, 1980).
NOTE 3: With few exceptions, the constituents of the F and K list waste
streams have been previously evaluated and a suggested RQ (reportable
quantity) determined. Entries in this column refer to the Specific
Chemical Waste on the U or P list in Table 9-1 where that evaluation was
made. Individual notes describe the evaluation of those few materials not
on the U and P lists. Sources of data for such evaluations are the same
as those given in Notes 2-5, Table 9-1.
NOTE 4: Entries in this column show the value in pounds that was assigned as a
reportable quantity under Section 311 of the Clean Water Act (40CFR117.3,
44FR10279-10283, February 16, 1979).
NOTE 5: Entries under this column are either (a) the lowest reportable
quantities derived for the constituents of the F and K list waste streams
as previously evaluated (see Table 9-1 where that evaluation was made) or
(b) the entries are flagged as follows to indicate why RQs have not at
this time been assigned, pending further assessment of the materials by
the Agency.
9-82
-------
# - to be assessed for carcinogenicity by GAG
f # - to be assessed for chronic toxicity by ECAO
### - to be assessed for both carcinogenicity and chronic toxicity.
P list wastes F001 - POOS may consist of any one of their constituents
alone, and therefore a numerical suggested RQ in pounds is shown for each
constituent of each waste, and the lowest of these RQ's is shown opposite
the description of the nature of the waste itself. For the remaining F
list wastes and each K list waste, which consist of a mixture of their
constituents, a numerical suggested RQ in pounds is shown opposite both
the constituents and the description of the waste itself (unless any of
the constituents are still being assessed for carcinogenicity or chronic
toxicity). This latter suggested RQ is the same as the lowest RQ
suggested for any constituent.
NOTE 6: Entries in this column show the basis on which an RQ has been
suggested, coded as follows:
311 - aquatic toxicity, as assigned under Section 311 of the Clean
Water Act
AQTX - aquatic toxicity, other than a 311 assignment
T(orl) - oral mammalian toxicity
T(ihl) - inhalation mammalian toxicity
T(skn) - skin (dermal) mamnalian toxicity
I - ignitability
R - reactivity
CT - chronic toxicity
For K list waste descriptions, the entry of the term "component" indicates
that the basis of the assignment is that constituent of the waste having
the lowest suggested RQ. See Note 5, above.
NOTE 7: A maximum RQ (5000 Ibs) is suggested for l,l,2-Trichloro-l,2,2-tri-
fluoroethane on the basis of the following data:
LD50 RAT = 43,000 rogAg (oral)
LC50 RAT = 87,000 ppn/6 hours (inhalation)
9-83
-------
NOTE 8: The suggested RQ takes into consideration one or more of the natural
dissipation processes of biodegradation, hydrolysis, or photolysis. More
specifically, the lowest RQ suggested by any of the primary ranking
factors has been adjusted upward one level.
NOTE 9: An RQ level of C (1000 Ibs) is suggested for ethylbenzene on the basis
of the following data:
Flash point = 59oF
Boiling point = 277oF
NOTE 10: All cyanides assigned reportable quantities under Section 311 of the
Clean Water Act (40CFR117.3, 44FR10279-10283, February 16, 1979) were
placed at RQ level A (10 Ibs) on the basis of the aquatic toxicity of the
cyanide ion. The same practice is continued here.
NOTE 11: An RQ level of D (5000 Ibs) is suggested for 1,2,3,-Trichloropropane
on the basis of the following data:
LD50 RAT = 320 mg/kg (oral)
IC50 = 1000 ppm/4 hours (inhalation)
NOTE 12: An RQ level of C (1000 Ibs) is suggested for 2,3-Dichloro-n-pro-
panol on the basis of the following data:
ID50 RAT = 90 mg/kg (oral)
LClo RAT = 500 ppm/4 hours (ihl)
NOTE 13: This is an aqueous waste, and it has been assumed that the antimony
compound in solution is the trichloride.
NOTE 14: An RQ level of D (5000 Ibs) is suggested for Diphenylamine on the
basis of the following data:
LD50 GPG = 300 mg/kg (oral)
NOTE 15: An RQ level of B (100 Ibs) is suggested for paraphenylenediamine on
the basis of the following data:
TLm(48) GOLDFISH = 5.7 ppm
9-84
-------
LD50 RAT = 80 rag/kg (oral)
NOTE 16: These esters are assumed to be composed of disulfoton and/or its
analogues, and accordingly an RQ level of X (1 lb) is suggested, based on
the RQ assignment of 1 lb given to disulfoton under Section 311 of The
Clean Water Act.
NOTE 17: These esters are assumed to be composed of phorate and/or its
analogues, and accordingly an RQ level will be suggested, based on the RQ
assignment of phorate itself, pending assessment of its chronic toxicity.
NOTE 18: Lead azide (explosive) is assumed to be one of these lead compounds.
NOTE 19: It is assumed that lead compounds in this waste derive from
tetraethyl lead; that is, they are the residues from leaded gasoline, and
that their toxicities and that of tetratethyl lead will be essentially the
same.

Appendix A
U.S. EPA CARCINOGEN ASSESSMENT GROUP PRELIMINARY CARCINOGEN RANKING
METHODOLOGY APPLIED TO SOME CERdA 101(14) POTENTIAL CARCINOGENS
A. THE APPROACH
1. Literature Searches
Biological data relevant to assessing carcinogenic hazard to humans is
searched both manually and by computer using appropriate key vords and data
bases. Current bioassay status is checked. Key articles are acquired for
evaluation.
2. Critical Review and Evaluation of Key Articles
Careful reviews and evaluation of key articles are performed by experienced
scientists. In the evaluation of carcinogenic data (whether positive or
negative), particular emphasis will be placed on ascertaining: (1) species
and strain tested; (2) age at start of test (including in utero); (3)
control groups; (4) number and survival of animals; (5) duration of testing;
(6) number of dose levels and dose selections; (7) route of administration;
(8) gross necropsy and histopatholcgic evaluation; (9) tumour incidence;
(10) site and type of tumours; (11) incidence of lesions other than tumours;
(12) tumours and other lesions in controls; and (13) method of evaluation of
experimental data. All of these factors are important determinants in
establishing carcinogenic activity for a chemical, and thus will be focused in
A-l
-------
the extraction and sutttnarization of data.
3. Summarizing the Weight-of-Evidence for Carcinogenicity
Using the IARC Criteria
After the data has been evaluated, they will be summarized as follows:
a. Weight-of-evidence statement using the IARC criteria
(1) Animal data
(2) Human data
b. Dose-response data that can be used for potency estimates
(1) Animal data
(2) Human data
4. Potency Factor Estimates
After the decision has been made that a compound has the potential for causing
cancer in humans, attempts will be made to estimate a potency factor F defined
as 1/ED,Q. ED _ is the estimated dose associated with a lifetime cancer risk
of 10%. The potency factor F will be used together with the qualitative
weight-of-evidence fbt Carcinogenicity in the ranking of the carcinogenic
hazard potential of the chemicals.
The potency factor F is used in place of the potency factor q* (the upper
confidence limit for the linear coefficient in the multistage model). The GAG
normally uses in the estimation of risk because the objective here is to rank
chemicals for their potential to cause carcinogenic harm and not to estimate
risk associated with a particular level of exposure. Furthermore, it is
advantageous to use the potency factor F because it can be estimated without
the use of many assumptions required for calculating and/or using q,*. This
is possible because the dose associated with a lifetime cancer risk of 10% is
A-2
-------
usually within or close to the experimentally observable range.
Other advantages of the potency factor F are:
A. It is relatively insensitive to the choice of the dose-response
extrapolation model.
B. The point estimation of ED1Q, which has some optimal statistical
properties, can be used to calculate F. Therefore, it is not
necessary to use the upper-bound estimate which is more stable for
estimating risk at very low doses.
The data used for the risk estimate is one or both of two types:
1. Lifetime animal studies
2. Human studies where excess cancer risk has been associated with
exposure to the agent
For animal data, the potency factor F will be calculated for a chemical using
the multistage dose-response model.
Under the multistage theory, the probability of cancer by age t with a
constant exposure d is given by
P(t,d) » 1 - exp [-Q (d) x A (t)]
\r
where Q(d) = q + ad + ... + ad and A(t) is some function of t. The
possible forms of A(t) have been extensively investigated and evaluated both
on human and animal data (e.g., Whittemore 1977). If only the cancer risk at
a specific time (age) t is of interest, the form of A(t) need not be
specified. The risk associated with a dose d for a given t within the
experimental range could be estimated by the procedure of Daffer et
al. (1980). In the cases where only dichotomous data are available, the
A-3
-------
formula without the term A(t) (i.e., A(t) = 1) would be used. If the
mortality rates among treatment groups are conparable, use of the formula with
or without A(t) would make no practical difference. The details of the risk
estimation procedure on the basis of animal data can be found in the Notice of
Water Quality Criteria Availability (U.S. EPA 1980).
The procedure for estimating risk on the basis of human data depends mainly on
the availability of data and the assumptions one is willing to make. The data
reported in an epidemiological study may range from a simple relative risk
estimate associated with a rough estimation of average exposure to the full
report on each individual in the cohort with respect to the time when exposure
began and terminated, age and cause of death, detailed work history, smoking
habit, etc.
Under the framework of the multistage theory, one could estimate the cancer
risk based on data obtained under various exposure patterns:
a. constant exposure concentration
b. exposure starting at age t and ending at t
c. Single exposure at t
An excellent discussion of these procedures can be found in Day and Brown
(1980), Whittemore (1977, 1978), Whittemore and Keller (1978). When making
risk estimate fran human data, one almost always has to make the assumption
that the exposure pattern is one of the three cases indicated above. Attempts
will always be made to use the model that has the least assumptions.
5. Potency factor Grouping
The potency factor estimates are indicators of relative potential to cause
carcinogenic harm. Although the numerical values themselves are not of major
importance for consideration in this assessment, they are useful tools to
separate the high, medium, and low hazard chemicals.
A-4
-------
When the relative potency factors are estimated by the procedure outlined in
(4) above, they will be grouped into four groups. Those chemicals with the
highest potency factors will be put in group 1, those chemicals with the next
highest potency factors will be put in group 2, the low potency factor
chemicals will be put in group 3, and the lowest potency factor chemicals will
be put in group 4.
One method of grouping is analysis for clustering in addition to potency
factor numerical value cutoffs. This requires analysis of all chemicals to be
completed before grouping can be done.
6. Hazard Ranking
Chemicals are ranked as high, medium, or low hazard by coribining the
qualitative weight-of-evidence for carcinogenicity and potency factor grouping
according to the following hazard ranking scheme.
A-5
-------
Hazard C&rcinogenicity Classification Potency Factor Group
High* Sufficient** and 1
Medium Sufficient and 2,3
1,2
Sufficient
Limited
Sufficient
Limited
and
and
and
and
Low Sufficient and 4
3,4
* In some cases we might judge that factors such as genotoxicity,
environmental persistence, and structure activity may warrant a
limited, potency 1 agent to be ranked as a high hazard.
** Sufficient here means sufficient evidence with respect to human
data and/or animal data.
B. SPECIAL ISSUES
1. Use of Chemical and Environmental Fate and Transformation
jji Assessing Metals and Their Salts
The chemical and environmental speciation; oxidation state; solubility;
chemical and environmental fate and half-life; disproportionation reactions
are important determinants of the toxicity of inorganic compounds.
Furthermore, it is anticipated that toxicological data on metals and their
salts are limited. When toxicity data on a particular metal salt is lacking
and an evaluation of these iinportant determinants indicates its convertibility
to the toxic/nontoxic species under the exposure conditions considered, then a
toxicity evaluation, based on the above-mentioned factor, should be performed.
A-6
-------
2. Multimedia Exposure
The media into which the toxicant is released will affect the form and
toxicity of the toxicant. Since the carcinogenic hazard assessment here deals
with multimedia exposure, if data are available for more than one route of
exposure, the one most sensitive to carcinogenic response will be used in the
estimation of potency. For example, respiratory exposures to nickel and
nickel compounds induce carcinogenic responses but oral exposure does not.
Thus, inhalation data will be used in estimating the carcinogenic potency of
nickel compounds.
3. Asbestos
The carcinogenic hazard of asbestos is associated with concentrations of
airborne fibers of certain size and not with mass. While larger asbestos
fibers may not be carcinogenic, they can subdivide into smaller carcinogenic
fibrils. Although the amount of asbestos in mass relates directly to its
carcinogenic potential, information such as asbestos type and potential for
fiber release per unit mass is needed before a hazard evaluation on a weight
basis can be made. Since this information is difficult to ascertain and
cannot be objectively predicted, asbestos carcinogenic hazard cannot be ranked
with other chemical agents where potency factor estimates are calculated on a
weight/volune concentration basis.
C. SAMPLE RANKING
Table A-l ranks 21 chemicals using the approach discussed in Part A. It is
important to note that while we do not expect changes in their ranking when
the assessment of all chemicals is completed, it is conceivable that those
chemicals on the borderline between potency factor groupings could change
position.
