FOREWORD
The U.S. Environmental Protection Agency was created because of increasing
public and government concern about the dangers of pollution to the health and
welfare of the American people. Noxious air, foul water, and spoiled land are
tragic testimonies to the deterioration of our natural environment. The
complexity of that environment and the interplay of its components require a
concentrated and integrated attack on the problem.
Research and development is that necessary first step in problem solution; it
involves defining the problem, measuring its impact, and searching for
solutions. The Hazardous Waste Engineering Research Laboratory develops new
and improved technology and systems to prevent, treat, and manage wastewater
and solid and hazardous waste pollutant discharges from municipal and
community sources, to preserve and treat public drinking water supplies, and
to minimize the adverse economic, social, health, and aesthetic effects of
pollution. This publication is one of the products of that research and
provides a most vital communications link between the researcher and the user
community.
This document provides the technical background for rulemaking pursuant to
Section 102 of the Comprehensive Environmental Response, Compensation, and
Liability Act of 1980 (CERCLA). It presents the methodology used to adjust
the reportable quantities of the CERCLA hazardous substances from their
statutory levels, the chemical-specific data used in the adjustment
methodology, the final reportable quantities for 340 hazardous substances, the
status of the remaining 358 hazardous substances, and other supporting
information.

PREFACE
This report was submitted to the Releases Control Branch, formerly the Oil and
Hazardous Materials Spills Branch, Office of Research and Development, Edison,
New Jersey, and the Emergency Response Division of the Office of Emergency and
Remedial Response of the Office of Solid Waste and Emergency Response of the
U.S. Environmental Protection Agency to provide the technical base for
adjustment of reportable quantities (RQs) for the hazardous substances defined
in CERCLA Section 101(14) and for which proposed RQs were listed in the May
25, 1983 Notice of Proposed Rulemaking (NPRM) (48 FR 23552 to 23602). It was
prepared by the technical staff of Environmental Monitoring & Services,
Incorporated (EMSI), a wholly owned subsidiary of Combustion Engineering and
formerly the Environmental Monitoring and Services Center of Rockwell
International Corporation. Principal authors are Mr. Franz J. Burmann,
Dr. Frank C. Gunderloy, Jr., Dr. Milton Kirsch, Mr. Greg Ricci, and Mr. Steven
C. Gibson. The EMSI and EPA staff also acknowledge the capable assistance and
guidance of Dr. Bart L. Tuffly, former senior project manager of this project,
who has recently retired.
The guidance of many members of the Environmental Protection Agency staff was
provided not only in a continuous fashion, but also in special working group
meetings and by written and oral comments on the various drafts. The
assistance of Dr. K. Jack Kooyoomjian, Mr. John Riley, Ms. Barbara Hostage,
and Mr. Richard Horner of the Emergency Response Division was especially
helpful.
The EPA project officer during most of the project was the late Mr. Leo
T. McCarthy, Jr., of the Releases Control Branch, Edison, New Jersey, who
provided invaluable guidance during the project. Recently his place has been
ably taken by Mr. Richard Field. The support and helpful suggestions of
Mr. James Janis, Mr. Michael Goldman, Mr. Jim Bunting and other staff members
of ICF, Incorporated, subcontractor to Environmental Monitoring & Services,
Incorporated, are acknowledged.

EXECUTIVE SUMMARY
The purpose of this report is to provide the U.S. Environmental Protection
Agency (EPA or the 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 from 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. Section 102(b) sets the
RQ of any hazardous substance defined in Section 101(14) at one pound except
those for which a different RQ has been established pursuant to Section
311(b)(4) of the Federal Water Pollution Control Act (also known as the "Clean
Water Act" or "CWA"). 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". CERCLA also allows EPA to
establish a single RQ for each hazardous substance regardless of the
environmental medium into which the substance is released.
EPA is adjusting the RQs of the hazardous substances designated in Section
101(14). This report addresses the methodology for adjusting the RQs of the
698 hazardous substances in Section 101(14). A companion report discusses the
economic and regulatory effects of this methodology.
* Unless otherwise specified, section numbers refer to CERCLA.
** The terms "notification" and "report" are used interchangeably in this
document.
ES-1

-------
THE SECTION 101(14) HAZARDOUS SUBSTANCE LIST
CERCLA Section 101(1A) defines a hazardous substance 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(a) of the Comprehensive Environmental
Response, Compensation and Liability Act,
C.	Any hazardous waste having the characteristics 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 (CAA), and
F.	Any imminently hazardous chemical substance or mixture with respect
to which the Administrator has taken action pursuant to Section 7 of
the Toxic Substances Control Act (TSCA).
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 under (A) through (F) above, and 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) .
The CERCLA Section 101(14) list consists of the following.
1. CWA Section 311 (40 CFR Part 117) - 297 hazardous substances are
designated with RQs assigned based on aquatic toxicity.
* The Solid Waste Disposal Act is now more commonly referred to as the Resource
Conservation and Recovery Act (RCRA).
ES-2

-------
2.	CWA Section 307(a) - 65 items are designated under the CWA Section
307(a), consisting of some classes and some Individual hazardous
substances. The EPA has identified 126 specific hazardous substances as
priority pollutants that fall within these 65 hazardous substances and
classes. Under CERCLA, RQs have been adjusted as indicated in this
report only for some of the 126 specific priority pollutants, because
some of the broad classes encompass a large undefined number of specific
compounds. Therefore, it would be'virtually impossible for the Agency
to develop a reportable quantity for a generic class of hazardous
substances that would take into account the characteristics of all the
specific priority pollutants.
3.	CAA Section 112 - eight hazardous air pollutants* (six of which are also
on the CWA Section 307(a) list) are designated under the CAA Section 112
(40 CFR Part 61.) (National Emission Standards have not been
promulgated for arsenic nor coke oven emissions.)
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 - 14 hazardous wastes from nonspecific sources
"K" List - 76 hazardous wastes from specific sources
The entire CERCLA Section 101(14) list comprises a total of 608 identifiable
separate hazardous substances with unique Chemical Abstracts Service Registry
Numbers (CASRNs) and 90 hazardous waste streams. Many hazardous substances
and hazardous wastes are duplicated on the various lists, and some appear in
the various lists under different names.
* The hazardous air pollutants are arsenic, asbestos, benzene, beryllium,
coke oven emissions, mercury, radionuclides, and vinyl chloride.
ES-3

-------
In addition to the 608 hazardous substances which are listed by unique CASRN
and the 90 hazardous waste streams, an indeterminate number of hazardous
wastes, defined in Subpart C of 40 CFR Part 261, and referred to as the
Unlisted Wastes, are also CERCLA hazardous substances. These Unlisted Wastes
exhibit one or more of the Characteristics of Ignitability, Corrosivity,
Reactivity or Extraction Procedure (EP) Toxicity (ICRE), as described in
Subpart C. The methodology for adjusting RQs to be discussed herein also
applies to these unlisted hazardous wastes, because if they meet these
characteristics, they are also CERCLA hazardous substances.
It should be noted that the lists which comprise the CERCLA Section 101(14)
list of hazardous substances are subject to change as these other lists
change. In the future, when hazardous substances are added to or removed from
the lists pursuant to the other statutes, corresponding changes will be made
simultaneously to the list of hazardous substances defined under CERCLA
Section 101(14).
PURPOSE OF RQ
The RQ serves as a trigger for notification that a hazardous substance has
been released, and to alert the response personnel that a judgment must be
made as to the necessity of a response. The response personnel are then in a
position to determine whether a Federal response should be made in accordance
with the National Contingency Plan (NCP) (40 CFR Part 300) authorized by
CERCLA Section 105. The government will exercise judgment in determining if a
response is required.
The RQs do not reflect nor imply a determination that a release of a hazardous
substance will be hazardous at the RQ level and not hazardous below that
level. EPA has not attempted to make such a determination because the actual
hazard will depend on the particular circumstances of each release. Response
personnel are charged with the responsibility for making this determination in
ES-4

-------
each individual case. The RQs reflect the Agency's judgment of which releases
should trigger government consideration of whether any response is necessary.
CANDIDATE METHODOLOGIES
Various methodologies have been considered for assigning RQs, as discussed
below:
Preferred Methodology for RQ Adjustment
The preferred methodology consists of two major steps. The entire process is
depicted as a decision tree in Figure ES-1. The first major step involves
evaluation of the physical, chemical, and toxicological characteristics of
each hazardous substance. The primary criteria examined are: ignitability,
reactivity, aquatic toxicity, acute mammalian toxicity (oral, dermal,
inhalation), chronic toxicity, and potential carcinogenicity. 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. If a hazardous substance is suspected of
being a potential carcinogen, its statutory RQ is retained and adjustment of
its RQ is deferred to a future rulemaking. For each of the five remaining
criteria, a five-tier rating scale is set up corresponding with RQ values of
1, 10, 100, 1000, and 5000 pounds. Since this five-tier system was
successfully used in the CWA and both the regulated community and response
personnel are familiar with It, EPA has decided to use this methodology for
CERCLA purposes. Unlike the CWA, CERCLA addresses all media, not only water.
Therefore, while the methodology selected to adjust the RQs of the designated
hazardous substances pursuant to Section 101(14) of CERCLA was based on the
precedent established In assigning RQs pursuant to the CWA Section 311, health
and welfare effects applicable to other media were also taken Into account 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 Preferred RQ Adjustment Methodology

-------
reactivity (I,C,R) are assigned an RQ of 100 pounds, in the middle tier of the
five-tier system.
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 pounds, its chronic
toxicity to an RQ of 5000 pounds, its aquatic toxicity to 10 pounds, its
mammalian toxicity to 100 pounds, and its reactivity to 1000 pounds, the final
RQ is 10 pounds, based on its aquatic toxicity. Reactive substances that
produce toxic products upon exposure to air or water are assigned RQs
characteristic of those products if those products lead to a lower RQ
assignment than would otherwise occur. Thus if a hazardous substance forms
hydrogen fluoride, hydrogen sulfide, or phosphine upon exposure to water, its
RQ may be that of the product if that RQ will be lower than would be assigned
by other primary criteria. This type of reactivity is in fact a hydrolysis
reaction. The Agency then evaluates each hazardous substance according to a
set of other criteria consisting of biodegradation, hydrolysis, or photolysis
(BHP). The primary criteria RQ is then raised one level if an analysis
indicates that the hazardous substance naturally degrades by BHP into less
hazardous products when released into the environment.
This methodology was chosen for adjusting the RQs of the 698 hazardous
substances including the 90 waste streams. The RQs of potential carcinogens
will be adjusted in a later rulemaking after the methodology being developed
by the Agency's Carcinogen Assessment Group (CAG) is subjected to rigorous
internal and external review. For 319 of the 608 individual CERCLA hazardous
substances and 21 of the 90 waste streams, the RQs are adjusted herein to
their final values. To date, EPA has fully assessed and published proposed
RQs for 64 of 245 substances that are to be assessed for chronic toxicity by
EPA's Environmental Criteria and Assessment Office (ECA0).
ES-7

-------
The advantages of this adjustment methodology are numerous. First, it is
technically and scientifically sound. Much of the germane data are readily
available. It provides flexibility because RQs can be adjusted in the light
of new data if necessary. The methodology is simple, understandable,
workable, and implementable, since both the regulated community and response
personnel are familiar with the notification scheme under the CWA.
SUMMARY OF ADJUSTMENTS
The table below summarizes the RQ adjustments.	The number	of hazardous
substances is given for each of five categories.	In addition,	the number of
hazardous substances that remain to be assessed	for chronic	toxicity and
potential carcinogenicity is given.

RQs have been finalized for 340 of the 698 designated hazardous substances,
raising 162, lowering 31, and leaving the other 147 unchanged from their
statutory RQ. For the remaining 358 hazardous substances, the final RQs are
flagged in Table 2-1 to indicate that they are subject to change when further
analysis for chronic toxicity or potential carcinogenicity, or both, is
complete (if such adjustments are deemed appropriate). For 105 of the
remaining 358 hazardous substances, which are identified by a double number
sign (##) in the final RQ column of Table 2-1, new RQs are proposed in
"Technical Background Document to Support Rulemaking Pursuant to CERCLA
Section 102, Volume 2, (Proposed Rulemaking)" March 1985.
ES-8

-------
Alternate Adjustment Methodologies Considered
The Agency considered a variety of RQ adjustment methodologies before adopting
the preferred methodology outlined above. None of these were sufficiently
well-developed or had sufficient data to be useful for RQ adjustment at this
time. Among the procedures investigated were those summarized below.
1. Leave all RQs as statutorily defined. For all hazardous substances
except the 273 whose RQs pursuant to the CWA Section 311 are larger
than one pound, the RQ would then remain at one pound because 24
hazardous substances were assigned 1-pound RQs by regulations
implementing the CWA. Reporting all releases at or above one pound
would not only subject the regulated community to a reporting burden,
but would also mean that the National Response Center (NRC) would
receive many telephone calls that would not warrant a federal
response.
2. Adopt RQs based on administrative feasibility as suggested by the
CERCLA legislative history. 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.
ES-9

-------
"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 has decided to base 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 3.
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. An obvious deficiency of this approach is that CERCLA
requires notification of reportable releases into the environment
which are beyond the scope of the navigable water perspective of the
CWA. CERCLA requires notification of releases into the air, onto the
land, and of releases which may enter groundwater as well as releases
into surface water. The Agency has, therefore, determined that
additional characteristics that may pose harm to the public health or
the environment should be taken into account.
4.	Adopt suitable scenarios to arrive at the RQ. Scenarios can be used
to develop a model of the behavior of hazardous substances after they
are released based on specific sets of circumstances that describe the
events likely to follow a release. On the basis of rough projections
of potential harm under scenarios of differing probabilities,
alternative RQs can be set. This alternative was rejected because of
its scientific complexity and because broad agreement that a
ES-10

-------
particular scenario is the most realistic that can be developed for
each particular hazardous substance is not likely.
5.	Fate and Effects 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
resource-intensive, time-consuming, and potentially inconsistent with
clear congressional intent to implement a relatively simple reporting
system.
6.	Hazard Index. A hazard index can be used to assign to each hazardous
substance a single number that represents the potential hazard of that
hazardous substance when released to all media. The system Involves
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 hazardous substances 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 hazardous substance 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 some 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 hazardous substance to
ES-11

SECTION 1
INTRODUCTION
The release of a hazardous substance in an amount equal to or greater than Its
reportable quantity (RQ) obligates the person in charge to notify the National
Response Center (NRC) by telephone as soon as that person has knowledge of the
release. The purpose of assigning RQs to hazardous substances is to allow the
On-Scene Coordinator (OSC), pursuant to the National Contingency Plan (NCP)
(40 CFR Part 300), to decide whether an immediate government response is
warranted and necessary to prevent escalation of and/or 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 U.S. Environmental Protection Agency (EPA or the Agency) has
used this principle as the basis for its RQ adjustments.
This report fully describes the preferred Agency methodology for adjusting the
RQs of the hazardous substances defined in the Comprehensive Environmental
Response, Compensation, and Liability Act (CERCLA) Section 101(14).
Alternative methodologies by the Agency are also discussed. In the
development of the preferred methodology, 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 commenters have been incorporated.
1-1
-------
The purpose of this document is to provide the EPA with the technical
background required to adjust the RQs of hazardous substances designated in
Public Law 96-510, the "Comprehensive Environmental Response, Compensation,
and Liability Act of 1980" (more commonly 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, also known as the Clean Water
Act (CWA),
B.	Any element, compound, mixture, solution, or substance designated
pursuant to Section 102(a) of CERCLA,
C.	Any hazardous waste having the characteristics 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 (CAA), and
F.	Any imminently hazardous chemical substance or mixture with respect
to which the Administrator has taken action pursuant to Section 7 of
the Toxic Substances Control Act (TSCA).
* The 1976 Act (PL-94-580) is more commonly known as the Resource Conservation
and Recovery Act (RCRA).

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 CWA, the CAA, and RCRA. The 297 chemicals designated as hazardous
substances pursuant to Section 311 of the 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 the CWA Section 311 are all 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 pounds, respectively. It should be emphasized that the scientific basis
for the RQ assigned is the aquatic toxicity of the substance, as measured in
screening tests using fresh water species. (Aquatic toxicity is discussed in
detail in Section 4.)
The 65 substances (including classes of compounds) that have been listed
pursuant to the CWA Section 307(a) are hazardous substances. This list could
include thousands of pollutants if all compounds in each class and all
organometallic compounds were considered. To implement the CWA Section
307(a), the Agency chose 129 individual compounds as priority pollutants.
However, three of these, bis(chloromethyl)ether, dichlorodifluoromethane, and
trichlorofluoromethane, have since been removed from the list, leaving 126.
Under CERCLA, RQs are being adjusted as indicated in this report only for the
126 specific priority pollutants, because some of the broad classes encompass
innumerable specific compounds. Therefore, it would be virtually impossible
for the Agency to develop an RQ for a generic class of hazardous substances
that would take into account the characteristics of all the specific hazardous
substances.
1-3
-------
Eight air pollutants (arsenic, asbestos, benzene, beryllium, coke oven
emmissions, mercury, radionuclides, and vinyl chloride) have been identified
pursuant to the CAA Section 112 as hazardous and are also hazardous substances
for Superfund purposes. National emission standards have been promulgated for
six hazardous air pollutants—asbestos, benzene, beryllium, mercury, certain
radionuclides, and vinyl chloride—in 40 CFR Part 61. Coke oven emissions,
and inorganic arsenic have been listed as hazardous air pollutants, but no
national emission standards have yet been promulgated. All substances
designated under CAA Section 112 as hazardous air pollutants, whether national
emission standards have been promulgated or not, are CERCLA hazardous
substances.
All of the hazardous wastes that have been identified in 40 CFR Part 261
pursuant to Section 3001 of RCRA are also hazardous substances. 40 CFR Part
261 identifies several types of hazardous wastes, and 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 14 hazardous wastes from nonspecific
sources. F001, for example, is described as, "The following spent halogenated
solvents used in degreaslng and sludges from the recovery of these solvents in
degreasing operations: tetrachloroethylene, trichloroethylene, methylene
chloride, 1,1,1-trichlorethane, carbon tetrachloride, and chlorinated
fluorocarbons." The K- list consists of 76 hazardous wastes from specific
sources. 40 CFR Sections 261.20 to 261.24 identify materials that exhibit the
Characteristics of Ignitability (I), Corrosivity (C), Reactivity (R), and
Extraction Procedure (EP) Toxicity (ICRE), but does not identify particular
compounds. EP toxicity is a characteristic of unlisted hazardous wastes
whereby toxicity is ascribed to them by identifying one or more specified
toxicants using a particular analytical technique that involves extraction as
a first step.

-------
To date, no action has produced a list of hazardous substances pursuant to
Section 7 of the TSCA.
CERCLA Section 102 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.
(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 CERCLA, the list of 297 hazardous substances designated pursuant to the
CWA Section 311(b)(2)(A) are assigned RQs pursuant to the CWA Section 311(b)(4).
For all other hazardous substances the statute requires that the RQs shall be
one pound.
When the May 25, 1983, Notice of Proposed Rulemaking (NPRM) was published, the
Agency did not have data on the majority of the hazardous substances relative to
their rankings nor suggested RQ assignments based on either chronic toxicity or
potential carcinogenicity. It also did not have available a proposed ranking
methodology based on potential carcinogenicity that was ready for extensive
review and comment. Thus, as indicated in the immediately preceding section,
there are a total of 358 hazardous substances listed as "to be assessed" (TBA),
by EPA's Environmental Criteria and Assessment Office (ECAO) for chronic
1-5
-------
toxicity or by its Carcinogen Assessment Group (CAG) for potential
carcinogenicity, or by both groups.
SUMMARY OF RQ ADJUSTMENTS
RQs for 319 hazardous substances and 21 hazardous waste streams have been
adjusted. The technical basis for those RQ adjustments is included in this
report. For some of the hazardous substances with RQs pursuant to the CWA
Section 311, it has been necessary to adjust the RQ downward. More recent
aquatic toxicity data than those available when setting the CWA Section 311 RQs
supports lower RQs for some of these substances. Since Superfund requires the
evaluation of additional criteria, the RQs may be lower for some substances
because of other criteria. Many of the RQs for hazardous substances have been
raised from the 1-pound level. The net effect of the use of the preferred RQ
adjustment methodology, explained in Section 2, is to decrease the number of
hazardous substances with 1-pound RQs from 405 to 258, as indicated below.

ORGANIZATION OF REPORT
Section 2 contains a discussion of the scientific and technical methodology 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
1-6
-------
toxicity, and potential carcinogenicity) and the other criteria,
biodegradability, hydrolysis, and photolysis (BHP). It also includes a table of
the 608 individual chemicals designated as hazardous substances, and of the 90
hazardous waste streams, with synonyms and final RQs. Alternative
administrative considerations that were not used are discussed in Section 3.
Sections 4 and 5 provide technical discussions on aquatic toxicity and mammalian
toxicity, respectively. Section 6 describes the technical information resources
employed in determining the basis for RQs for the hazardous substances. Section
7 contains the data tables supporting the final RQs displayed in Section 2 for
the CWA and CAA chemicals. Section 8 contains similar data tables for the RCRA
hazardous wastes. Appendix D contains a description of a possible alternative
method for adjusting RQs, the Hazard Index approach, that is not used in the
preferred methodology.

SECTION 2
METHODOLOGY FOR RQ ADJUSTMENT AND ASSIGNMENTS
TO THE CERCLA SECTION 101(14) LIST
LIST OF HAZARDOUS SUBSTANCES AND FINAL RQs
Table 2-1 lists all of the CERCLA hazardous substances and their final RQs,
together with their original statutory RQs and other pertinent information.
The final RQ of each hazardous substance still being assessed for potential
carcinogenicity and/or chronic toxicity is followed by a symbol, either (If) or
(#//), to alert the regulated community that it is subject to change after the
assessment is complete. The single number sign symbol (//) indicates that the
final RQ listed is subject to change in a future rulemaking, whereas the
double number sign symbol (#//) indicates that the final RQ listed is subject
to change in an NPRM being published in the same issue of the Federal Register
as the final rule for which this report provides technical background. (See
Technical Background Document to Support Rulemaking Pursuant to CERCLA Section
102, Volume 2 (Proposed Rulemaking), March 1985.) These hazardous substances
thus retain their statutory RQs; either the 1-pound RQs mandated by CERCLA or
the CWA Section 311 RQs specified by AO CFR Part 117. (For more details on
the nature of pending assessments as well as the data used in the adjustment
of RQs, refer to Tables 7-1, 8-1, and 8-2.)
The list of hazardous substances is arranged alphabetically and identifies the
statutory source for designation under CERCLA Section 101(14) by numerical
code in the Statutory Code column. (The hazardous substances designated under
the CWA Sections 311(b)(2)(A) 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 hazardous substances are regulated by more than one
statute and may be identified under different names in the different statutes,
all the names under which the hazardous substance is listed pursuant to any
statute or implementing regulation are included in the alphabetical list and

the synonyms included in the Regulatory Synonyms column. Each hazardous
substance is uniquely identified by its Chemical Abstracts Service Registry
Number (CASRN). A sequential listing by CASRN is provided in Appendix A for
the convenience of the reader.
Additional CASRNs are included for the CWA Section 311 designated hazardous
substance families, hydrates, esters (e.g., 2,4,5-T esters) and solutions.
The generic groups of, chemicals designated under CWA Section 307(a) such as
"SILVER AND COMPOUNDS" are printed in all-capital letters and have no RQ
assigned to them.
The list also Includes the 90 hazardous waste streams designated under 40 CFR
Sections 261.31 and 261.32 (RCRA F- and K-lists). These waste streams contain
CERCLA hazardous substances, and the RQs for these waste streams are based on
those hazardous constituents. Many of the waste streams in 40 CFR
Sections 261.31 and 261.32 have more than one hazardous constituent. One RQ,
which represents the lowest RQ of all 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 as
well as for each individual waste stream. The wastes F001 through F005 are
treated differently because each of these wastes is a collective listing of
different individual solvents. A listed waste may be one or a mixture 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 CERCLA Section
101(14) list in the following manner:
1. CWA Section 311 - 297 chemicals which are listed in 40 CFR Part 117
2-62
-------
and which have RQs assigned based on aquatic toxicity (acute toxicity
to aquatic organisms)* In many cases, the hazardous substances
listed in AO CFR Part 117 refer to isomers and multiple compounds 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" (CASRN 1319733), but also the listing of cresol's isomers,
i.e., the ortho-, meta-, and para- isomers (CASRNs 95487, 108394, and
106445, respectively). Similarly, while no specific names are given
under the entry "2,4-D Esters," CASRNs for 10 different compounds are
listed. Where isomers and multiplicities of compounds exist for the
CWA hazardous substances they have been shown and all the individual
CASRNs 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 priority pollutants were
derived from the original 65 broad generic classes, such as
"chlorinated benzenes," "chlorinated phenols," "haloethers,"
"halomethanes," and "polychlorinated biphenyls." The 126 specific
chemicals were arrived at after a series of negotiations between the
Agency and the plaintiffs in the case that resulted in what is
commonly known as the "Consent Decree."
3.	CAA Section 112 - eight chemicals. 40 CFR Part 61 lists National
Emission Standards for six of these hazardous air pollutants.
4.	TSCA - no entries.
2-63
-------
5. RCRA Section 3001 - 40 CFR Part 261 lists the following:
A. Specific chemical wastes -
"U" List	-	233 chemicals
"P" List	-	107 chemicals
6. Waste streams -
"F" List	-	14 wastes
"K" List	-	76 wastes
Since many hazardous substances are listed under more than one environmental
statute, there are some duplicate entries. After these duplicate entries are
discounted, the CERCLA Section 101(14) list comprises a- total of 608 uniquely
identifiable hazardous substances and 90 waste streams. Of these 608
hazardous substances, the 297 chemicals designated as hazardous substances
pursuant to the CWA Section 311 have previously been assigned RQs of 1, 10,
100, 1000, or 5000 pounds, based on their level of aquatic toxicity. For the
remaining 310 hazardous substances, CERCLA assigns an RQ of one pound (CERCLA
Section 102(b)). These statutory RQs were intended by Congress 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 potential threats to public
health or welfare or the environment, and will relieve the regulated community
and emergency response personnel (including the NRC) from the burden of
reporting releases that are unlikely to pose such threats. The methodology
presented herein provides a simple, understandable, and implementable
framework to assign RQs.
2-64
-------
THE PREFERRED RQ ADJUSTMENT METHODOLOGY
Basic Methodology
The preferred methodology for RQ adjustment consists of evaluating the
intrinsic properties of the hazardous substances designated by definition in
CERCLA Section 101(14), and associating these properties with a five-tier
ranking scale to arrive at a single adjusted RQ for each hazardous substance.
The intrinsic properties are ignitability, reactivity, aquatic toxicity,
mammalian toxicity (oral, dermal, inhalation), potential carcinogenicity, and
chronic toxicity. For each of these properties (except potential
carcinogenicity, for which a ranking scale is still under development), a
ranking scale was set up to permit a hazardous substance to be placed at one
of five levels as 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 hazardous substances exhibiting the least severe
value of each characteristic being assigned the highest possible RQ for that
property.
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 original association between RQ values and the
intrinsic characteristics was derived from the CWA reportable quantity
methodology. The Agency decided it was practical to utilize and expand upon
this basic CWA methodology.
The final adjusted RQ for a particular hazardous substance is the lowest RQ
assigned for any of the intrinsic properties. The overall methodology used in
adjusting the RQs consists of associating the intrinsic physical, chemical,
and toxlcologlcal properties (i.e., the primary criteria) of the hazardous
substances with administratively selected but technically derived RQ levels to
arrive at a primary criteria RQ. Finally, intrinsic degradative properties
2-65
-------
(the ability to undergo biodegradation, hydrolysis, and photolysis - BHP) are
applied to make final RQ adjustments where appropriate.
Use of the Primary Criteria and Other Factors for Adjusting RQs
The methodology for adjusting the statutory RQs is summarized in Figure 2-1.
As noted above, the methodology used in arriving at the RQ adjustments in this
report for the' CERCLA Section 101(14) list is based on a rating system using
six primary criteria: aquatic toxicity, mammalian toxicity (oral, dermal,
inhalation), chronic toxicity, ignitability, reactivity, and potential
carcinogenicity. Each material is evaluated pursuant to these primary
criteria, and the lowest possible RQ assigned based on these primary criteria.
Then, whenever appropriate, further RQ adjustment is made based on BHP.
The five-level RQ rating system derived for aquatic toxicity under the CWA
Section 311 is used as a baseline for this analysis. (See Preamble to Final
Rulemaking A3 FR 10492, March 13, 1978.) This RQ rating system consists of
the following five RQ categories, linked to the specified aquatic toxicity
ratings:
Category	Aquatic Toxicity	RQ (Pounds)

Figure 2-1. The Preferred RQ Adjustment Methodology
-------
For each hazardous substance on the CERCLA Section 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 pound], A
[10 pounds], B [100 pounds], C [1000 pounds], or D [5000 pounds]). Some
hazardous substances may not, due to their inherent characteristics, exhibit
all the primary criteria. For instance, some hazardous substances are not
ignitable or reactive. Accordingly, these characteristics are not evaluated.
The primary criteria RQ is the lowest RQ derived from the six primary criteria
characteristics of a hazardous substance. For example, the following RQ
values were determined for the primary criteria for ammonium sulfide (see
Table 7-1, page 7-5).
In this case, the primary criteria RQ assigned to ammonium sulfide is
100 pounds, based on the lowest values determined for the Individual criteria.
A more detailed description of the steps that were followed in the RQ
adjustment methodology for all compounds is given below. (Refer also to
Figure 2-1.)
1.	The aquatic toxicity, mammalian toxicity, ignltabillty, and
reactivity data for each hazardous substance (where appropriate) were
evaluated and the data for that criterion which resulted in the
lowest RQ assignment were used as the basis for the final RQ. These
data are tabulated In Tables 7-1, 8-1, and 8-2.
2.	The ECAO, EPA-Cincinnati, a part of EPA/ORD's Office of Health and
Environmental Assessment (0HEA) has developed a five-tier chronic

toxicity ranking procedure that incorporates a combination of minimum
effective dose and severity of effect. The ECAO had assessed only 64
hazardous substances for chronic toxicity when the May 25, 1983 NPRM
was published and was still evaluating chronic toxicity data for
another 181 hazardous substances. Since that time ECAO has completed
its assessment of these remaining 181 hazardous substances.
Ninety-seven (97) of these appear in "Technical Background Document
to Support Rulemaking Pursuant to CERCLA Section 102, Volume 2
(Proposed Rulemaking)," March 1985. The remaining 84 were also
evaluated by CAG for potential carcinogenicity and their RQs will be
adjusted in a future rulemaking. (See Tables 7-1 and 8-1.
Substances being assessed by ECAO are identified by CKRON TBA.)
3. If a hazardous substance was identified as a potential carcinogen, it
was labeled "CARC TBA" in Tables 7-1, 8-1, and 8-2 pending
development and application of an appropriate ranking method by the
Agency's CAG, also a part of OHEA.
RQ Scale for Aquatic Toxicity —
The RQ scale used in the RQ adjustment process described here was originally
developed by the Agency in promulgating regulations under the CWA Section 311.
It relates aquatic toxicity to reportable quantities in a five-tier system as
shown in the table on p.2-66. (For a complete explanation of the technical
basis for the 5-tier RQ scale and its relation to aquatic toxicity see
Preamble to Final Rulemaking 43 FR 10492, March 13, 1978, and the associated
technical background documents, EPA-440/9-75-(a-d), January 1975.)
In that table, the term LC^q stands for the lethal concentration (LC) in
water, expressed as milligrams per liter (mg/1) that will kill 50% of a test
population. The term TL^ (median tolerance limit) is sometimes found in the
literature, and is equivalent to	when exposure times are the same. For a
more detailed discussion of aquatic toxicity, see Section 4.
2-69
-------
In Tables 7-1 and 8-1, the RQ previously established on the basis of aquatic
toxicity in 40 CFR Part 117 under the CWA Section 311 is identified in either
a column headed "311 RQ," or as the basis for assigning an RQ, shown as "311."
Of the 297 hazardous substances listed under the CWA Section 311, the RQs for
19 hazardous substances have been changed; however, assessment of all 297
hazardous substances is not yet complete for chronic toxicity and potential
carcinogenicity and therefore the RQs will most, likely be changed for a total
of 40 CWA Section 311 hazardous substances. Such changes are justified by the
fact that characteristics such as mammalian toxicity, chronic toxicity,
ignitability, corrosivity, and reactivity must be considered for the purposes
of CERCLA (i.e., multimedia releases) and these factors were not considered in
arriving at the CWA Section 311 RQs, which were based on releases to water
only. In some cases, the CWA Section 311 RQs were also adjusted on the basis
of newer aquatic toxicity data. In the process of making such adjustments for
the CWA Section 311 hazardous substances, more recent aquatic toxicity data
appearing in the EPA's Ambient Water Quality Criteria Documents and the
Department of the Interior (DOI) publication, "Handbook of Acute Toxicity to
Fish and Aquatic Invertebrates" were used. Since acute aquatic toxicity is
one of the primary ranking factors in this scheme, it became the basis on
which an RQ was determined if it resulted in the lowest value from all
assessed criteria. This has the effect of maintaining the CWA Section 311 RQs
in the majority of cases. A more detailed analysis of the status of the CWA
Section 311 hazardous substances is given below.
In assigning RQs to substances not listed under CWA Section 311, aquatic
toxicity data from the Oil and Hazardous Materials Technical Assistance Data
System (OHMTADS) were accessed via the Chemical Information System (CIS) (see
Section 6) and were 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 and the DOI publication cited above.
2-70
-------
As a special case, all cyanide-containing hazardous substances (including the
generic class) were assigned an RQ of 10 pounds based on the aquatic toxicity
of cyanide as developed under the CWA Section 311. None of the other
criteria, Including the inhalation toxicity of hydrogen cyanide, justify a
lower RQ for other cyanide compounds.
Status of Substances Designated Under the CWA Section 311— Forty hazardous
substances originally designated under the 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 hazardous substances into different
reportable quantity categories than those previously assigned under the CWA
Section 311. This newer aquatic toxicity data is tabulated in Tables 7-1 and
8-1 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 CERCLA, not all of these 40 hazardous substances had their RQs
changed on the basis of this newer aquatic toxicity data. The net effect is
as follows. Twenty-one of the AO hazardous substances have been placed in the
"to be assessed" category for either potential carcinogenicity and/or chronic
toxicity, hence their RQ is subject to further adjustment. RQs for four of
those are being proposed in an NPRM being published simultaneously in the
Federal Register with the final rule for which this document provides
technical background. The final adjusted RQs for 12 of these hazardous
substances is lower than their CWA Section 311 RQs because of the new aquatic
toxicity data. Nine of these are lower because of the new aquatic toxicity
data alone (dinitrophenol, 2,4-dinitrophenol, mercaptodimethur, naphthalene,
4-nitrophenol, n-butyl phthalate, dichlobenil, kelthane, and pyrethrins).
Three others are lower based on the new aquatic toxicity data in combination
with one or more of the primary criteria (nitrophenol, phosphorus oxychloride,
and phosphorus trichloride). The final adjusted RQs for four of these
hazardous substances is higher than their CWA Section 311 RQs because of the
new aquatic toxicity data (2,4,5-T acid, 2,4,5-T amines, 2,4,5-T esters, and
2,4,5-T salts). The RQs of the remaining three hazardous substances were
2-71
-------
initially lowered using the newly available data, but were readjusted upward
using BHP (acetyl chloride, butyl acetate, and triethylamine). The 40
hazardous substances are identified in Table 2-2, along with their CWA Section
311 RQs, their CERCLA final RQs, and the basis for the final 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	values (oral and dermal toxicity) or LC^q values
(inhalation toxicity). The term	means the 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 LC^q means the
lethal concentration (LC) in air, expressed in parts per million (ppm) that
will kill 50% of the test animal population. More details on the nature of
mammalian toxicity studies are given in Section 5.
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 pounds)
as had been done in developing regulations under the CWA Section 311 (see
References cited on p. 2-69 in paragraph on RQ Scale for Aquatic Toxicity).
The ranges corresponding to categories X, A, B, and C (1, 10, 100, and
1000 pounds) 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.2-66).
The upper limit for dermal toxicity was 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 limit
was used in a five-tier scale developed by the National Academy of Sciences

(HAS) in a study done for the United States Coast Guard (USCG) (1) . The NAS
study also provided the upper limit for the Inhalation toxicity scale.
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 inadvertently to 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 LD,.q 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 accidental poisoning of children, Dr. Howard Mossensen at the
Nassau County Medical Center on Long Island, New York. Dr. Mossensen agreed
that the assumptions were reasonable and would provide a high degree of
protection in the event of such an exposure (2).
In assessing hazardous substances under this criterion, ^D^q values from
animal studies were used; statistically valid human	values are available
in only isolated cases, since human populations are not generally subjected to
deliberate toxicity studies. Data on human toxicity are generally reported as
LD^o values. The term LD^0 means "low lethal dose," and refers to the lowest
dose on record believed to have caused a fatality. Human	data are not

-------
especially reliable, since they derive from Individual incidents of accidental
human poisoning, and generally rely on information reported about the victim,
regardless of the validity of such a report. For example, the	(oral rat)
of sodium chloride (common table salt) is 3000 mg/kg, but the recorded human
LD^q is only 500 mg/kg. The Agency clearly does not consider such a commonly
used item as sodium chloride a hazardous substance.
When data for more than one mammalian toxicity route are available, the value
chosen for the mammalian toxicity criterion represents the lowest of the
values derived from the three scales. For example, if inhalation toxicity
yields an RQ of one pound, while oral and dermal exposures yield values of ten
pounds, then the RQ based on mammalian toxicity would be one pound.
Available mammalian toxicity data came from the National Institute of
Occupational Safety and Health (NI0SH) Registry of Toxic Effects of Chemical
Substances (RTECS) via CIS. RTECS is updated quarterly, and currently
contains toxicity information for some 63,000 compounds.
Nonequivalence of Toxicity Scales— Although the three mammalian toxicity
scales (oral, dermal, inhalation) and the aquatic toxicity scale are each
equated to the same RQ categories and poundage levels, the scales are not
necessarily equivalent to each other. Each scale may be considered an
independent entity; potential danger to human health, welfare, and the
environment may or may not be equivalent when substances have the same ranking
on different scales. Acetic acid, for example, which has been assigned a
1000-pound RQ on the basis of aquatic toxicity probably does not present the
same danger or hazard as silver which has been assigned a 1000-pound RQ on the
basis of chronic toxicity. However, in other cases, the hazards created by
individual substances under particular circumstances could be quite similar.
2-77
-------
RQ Scales for Ignitability and Reactivity Evaluations—
The starting point for the rating scales for RQ adjustment based on the
parameters of ignitability and reactivity also have their origin in work done
by the NAS for the USCG (1). This USCG report describes the development of a
five-level system to evaluate these factors, as shown in Table 2-4. As
discussed below, these scales were modified by the Agency.
Exclusion of the X (1-pound) RQ Level— Small releases (i.e., one pound) of
flammable, reactive, or explosive hazardous substances are handled by the
spiller, or by state and/or local responders such as fire departments, police,
bomb squads, and so on. The EPA or USCG will not usually respond to such
incidents because these incidents are generally handled effectively at the
state and local levels. EPA does not intend to require notification of such
releases. Furthermore, small releases (less than ten pounds) of ignitable or
reactive hazardous 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 Category X
(1-pound) RQ level for all the ignitability and reactivity scales discussed
below and set the lowest possible ratings based on these factors equivalent to
the next higher Category A (10-pound) RQ level. This change met with approval
during interviews with field personnel.
Ignitability Scale Adjustment— The NAS scale (Table 2-4) 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
hazardous substances have this characteristic, and are classified as follows:
Pyrophorics: Those substances that immediately ignite because of rapid
oxidation as soon as they contact oxygen

immediately ignite, but that can do so if spread in a thin layer, or
brought into contact with iron oxide or other catalysts
Strong Oxidizers: Those hazardous substances 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 "noncombustible" 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 (140°F) corresponds with the upper limit used to assess the
Characteristic of Ignitability in the regulations issued under RCRA,
40 CFR Section 261.21.
The three upper numerical categories correspond to National Fire Protection
Association (NFPA) classes, as cited in NFPA document No. 30 (3). This
document is updated periodically. However, the flammability and
combustibility classes have not changed in recent editions. The
correspondence is as follows:

In a final step, this ranking system was set equivalent to the RQ categories,
as follows:
Water Reactivity Scale Adjustment— The NAS water reactivity scale ignores a
very important aspect of this characteristic, namely the case of hazardous
substances 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-pound level) for such
compounds. This Includes such hazardous substances as sodium, the other
alkali metals, calcium carbide, and a number of other hazardous substances
that are identified by the U.S. DOT as Flammable Solids (Dangerous When Wet).
Both reactivity scales, as well as the ignitability scale, are shown in Table
2-5, 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 hazardous 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 In
the regulations issued under RCRA, 40 CFR Section 261.23, to assess the
Characteristic of Reactivity (i.e., reactive with water, capable of
detonation, normally unstable, explosive decomposition). The RCRA factor not
covered is that certain wastes mixed with water or acid can generate toxic
gases. One case is that of the cyanides, which can be ranked appropriately on
the basis of the CWA Section 311 ranking for cyanides. Other hazardous
substances, such as those that could generate phosphine (PH^), hydrofluoric
acid (HF), or hydrogen sulfide (I^S) have been treated as special cases of
reactivity, and have been addressed as such with individual discussion when
ranked (see Tables 7-1, 8-1, and 8-2). See also Table 2-8 and later
discussions in this document related to BHP factors.
RQs Based on Structural Similarity—
Data were available to adjust RQs on the basis of the primary criteria for
most of the CERCLA hazardous substances. However, six hazardous substances
that had little available data on the primary criteria were assigned RQs based
on the adjusted RQs for other hazardous substances similar in structure and
substltuents. The hazardous substances are:
1.	4-Chlorophenyl phenyl ether
2.	Dlchloropropane
3.	Dinitrophenol

5.	Nitrophenols

6. 2-Nitrophenol
In these six cases the similarity to other hazardous substances is so close
that this assignment process is considered completely valid. Thus, data from
both monobromo- and tribromomethane are available (Table 8-1) to indicate the
RQ to assign to the dibromo- compound. Nitrophenols, dinitrophenol,
hexachlorocyclohexane, and dichloropropane are assigned RQs on the basis of
their specific isomers for which data are available (e.g., dichloropropane is
assigned, the same RQ as determined for the specific isomer
1,2-dichloropropane). Finally, 4-chlorophenyl 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 pounds).
The Use of 1-Pound and 10-Pound RQ Levels—
The 1-pound RQ is consistent with prior regulation under the CWA (see
40 CFR Part 117), and most of the regulated community has accepted the 1-pound
level as appropriate. One pound was selected for the CWA as the lowest
reporting level because one pound Is typical of the smallest container size
commonly used in commerce (40 FR 59989, December 30, 1975). Also, as noted
earlier, the Agency interviewed a large cross-section of field response
personnel, and all of those Interviewed indicated that they want to be
notified of most releases, even at the 1-pound level. In the interviews, the
field response personnel recognized that the government may not actively
respond to many 1-pound releases, but they noted that notification was a
prerequisite for determining (1) the need for a response under the
circumstances, (2) the adequacy of any cleanup efforts, and (3) the degree to
which post-release monitoring may be required. Furthermore, many releases
tend to be escalating events, and early notification helps ensure an effective
response.
2-84
-------
However, as a result of interviews with federal government field response
personnel, the Agency decided to remove the 1-pound RQ level from the
ignitability and reactivity RQ scales. Government response personnel
indicated that releases of less than ten pounds of ignitable and reactive
substances normally would be adequately handled by appropriate local or state
response personnel, and they concurred with the Agency's proposal to raise to
ten pounds the minimum reporting level for the ignitability and reactivity RQ
scales. Government response personnel, however, objected to raising the
minimum reporting level any further. They maintained that reporting levels
should be kept low in order to ensure timely reporting of potentially harmful
releases and timely government response, if necessary. The RQ thus serves as
a trigger, which allows response personnel to be informed of potentially
dangerous situations, and allows them to initiate appropriate action under the
NCP.
Assignment of RQs on the Basis of Chronic Toxicity and Potential
Carcinogenicity—
The health, welfare, and environmental factors used to assign RQs using the
primary criteria may be classified into two categories:
1.	Those criteria characterized by some acute or immediate threat;
2.	Those criteria characterized by a threat that is not immediately
identifiable.
The first category, those criteria characterized by some acute or immediate
threat to human health, welfare, or the environment, are visibly identifiable
in fatal poisonings of mammals or aquatic organisms, or in fires, explosions
or violent reactions. The criteria that readily consider such acute threats
are acute aquatic toxicity, acute mammalian toxicity, ignitability, and
reactivity, and these have been discussed in the immediately preceding section
of this document. The second category of factors used to assign RQs are
characterized by threats to human health or welfare that are not immediately
2-85
-------
identifiable. An example of such a threat is the concern about asbestos as
the potential agent underlying current health problems in persons exposed to
asbestos fibers as shipyard workers for prolonged periods in the 1940's. The
criteria of chronic toxicity and potential carcinogenicity are being examined
to evaluate hazardous substances such as asbestos, which may exhibit toxic
threats even after a long lapse of time between exposure and manifestation of
the toxicity, or which may Induce some damaging effects as the result of
prolonged exposure at doses which are less than lethal.
Chronic toxicity, which is a function of prolonged exposure, should be
considered an important aspect of the RQ program, despite the emphasis on
episodic releases. While the May 25, 1983, NPRM preamble stated chat the
Agency would focus its enforcement efforts on episodic releases pending
implementation of CERCLA Section 103(f)(2), RQs are not restricted to episodic
releases either by CERCLA or by the Agency's interpretation. As noted in the
NPRM preamble, the Agency decided to use chronic toxicity as a criterion in
setting RQs because episodic releases which are not completely cleaned up may
result in repeated or continuous exposure to a toxic substance. Moreover,
CERCLA covers both episodic and continuous releases. Continuous releases may
lead to repeated or continuous exposure to toxic hazardous substances.
Under CERCLA Section 101(14), 698 hazardous substances are designated
including 90 RCRA waste streams. It would be both costly and time-consuming
for the Agency to analyze each one of these hazardous substances to determine
its chronic toxicity and/or potential carcinogenicity because of the complex
analyses required for these criteria. As a result, the CERCLA Section 101(14)
list of hazardous substances was initially reviewed to identify those
hazardous substances that may exhibit chronic toxicity and/or potential
carcinogenicity. The ECA0, located in Cincinnati, Ohio, is performing the
assessments of those hazardous substances suspected of exhibiting chronic
toxicity. Potential carcinogens are being evaluated by the Agency's CAG. The
screening process that the Agency used to identify those CERCLA Section
101(14) hazardous substances for further evaluation by ECA0 and CAG will be
2-86

discussed in the sections that follow.
Development of a Chronic Toxicity Ranking Process—
Chronic Toxicity Defined— For purposes of this report, chronic toxicity is
defined as toxicity due to repeated or continuous exposure from a single
release or multiple releases of a designated hazardous substance (exclusive of
oncogenic effects).
Selection of Hazardous Substances for Chronic Toxicity Evaluations— The
CERCLA Section 101(14) list of hazardous substances was screened in order to
identify those hazardous substances to be analyzed by ECAO. Seven sources of
information were examined in order to establish which of the CERCLA hazardous
substances had been the subject of one or more studies evidencing chronic
toxicity. These seven sources were selected because each is the product of
some prior or ongoing major study emphasizing the collection of information
about the biological effects of chemicals. The sources were further selected
because they represent a variety of interests: regulatory support, general
toxicology, water quality, pesticide applications, and general environmental
effects.
The seven sources are:
1. "The Registry of the Toxic Effects of Chemical Susbstances," RTECS,
accessed as a machine-searchable data base via the CIS. RTECS now
contains information on over 63,000 chemical substances, with the
data summarized as succinctly as possible. A typical RTECS entry
listing a chronic effect will give a numerical value for the toxic
dose (TD^q or TDiq - note the distinction between this and a lethal
dose,	or LD, ; and an abbreviation indicating the organ or
system affected. For example, a common RTECS entry is "CNS," which
stands for "central nervous system."
RTECS is also available in hard copy, the latest being DHHS (NIOSH)

7. "Report on the Environmental Assessment of Pesticide Programs." This
document was prepared in 1978 by the California Department of Food
and Agriculture, and was initiated as the result of the California
Environmental Quality Act and a related Opinion generated by the
Attorney General, State of California. It contains an extensive
review of the environmental and health effects of various types of
insecticides, herbicides and other types of pesticides. Emphasis is
on the health effects, and how these are related to pesticides,
rather than on the individual chemicals.
In conducting the review of these data sources, no attempt was made to
distinguish between relatively short-term (weeks, several months) subacute
effects and long-term (many months, years) effects. Both were considered as
indicators of chronic toxicity. The review resulted In a list of 245
hazardous substances for further chronic toxicity assessment by ECAO. These
245 hazardous substances were derived from an earlier and longer list, which
was originally prepared for and used by ECAO. However, those hazardous
substances that already had an adjusted RQ of 1 pound based on the other
primary criteria (aquatic toxicity, acute mammalian toxicity) were not
considered for chronic toxicity evaluation, since the lowest RQ level that can
at present be assigned to the hazardous substances had already been assigned.
Thus, a number of hazardous substances which were known to have chronic
effects were excluded from ECAO analysis because further evaluation could not
change their RQ assignment. ECAO's methodology had already been developed, so
the evaluation of these 1-pound RQ substances for purposes of testing the
methodology was deemed unnecessary.
Chronic Toxicity Ranking— The chronic toxicity ranking procedure developed by
ECAO is not Intended to provide an absolute measure of harm for the CERCLA
Section 101(14) hazardous substances being evaluated, nor is it intended to be
a risk assessment. It is only a relative hazard ranking system suitable for
providing a basis on which to assign RQs. The major elements of the ECAO
methodology are described here. For more details refer to Appendix B.
2-89
-------
The ECAO chronic toxicity ranking is based upon two primary attributes of each
substance:
o The minimum effective dose (MED) levels for chronic exposures
(mg/day for 70-kg man) via alternative environmental media (air,
water, etc*)
o Type of effect (liver necrosis, teratogenicity, etc.)
The MED is the lowest dose level that can be identified having any effect on
an organism under study. In order to have consistent values, animal MEDs are
converted to human MEDs by a mathematical expression that relates body weight
of the animal to body weight of a human. For the human body weight, 70 kg is
used. This is the weight for the "standard man," a value that has been
defined and agreed upon by the scientific community for biological
applications. The "standard man" MED then is utilized to determine a rating
value based on dose (RV^) for each of the hazardous substances evaluated for
chronic toxicity. MEDs are converted to RV^s using the scale shown in Figure
2-2. The RVd values may range from 1 to 10 depending on the toxicity of the
hazardous substance being evaluated. In this way, hazardous substances having
a- chronically toxic effect at a low dose (i.e., those that are more highly
toxic) will be given a high rating on this graph. Correspondingly, those
hazardous substances requiring a large dose to produce a chronically toxic
effect are less toxic and will be given a low rating on the graph. Similarly,
the type of effect produced by a particular hazardous substance is given a
rating value based on effect (RVg, see Table 2-6). These RVg values range
from one to ten depending on severity of the effect, with 10 being the most
severe. Finally, a composite score is determined for each substance by
multiplying the rating value for dose (RV^) by the rating value for effect
(RVg). The possible range of composite scores is thus 1 to 100. These
resulting composite scores are then correlated with the five RQ levels as
follows:

B.) The plot above is presented in order to demonstrate
the relationship of MED vs ^ in a simplified format.'

Certain estimative techniques must be used to make the ECAO methodology as
broadly applicable as possible. Two techniques that have proven particularly
useful are the methods of estimating human MED from animal data using a cubed
root of body weight ratio approximation, and the use of subchronic data to
estimate a chronic value by dividing by an appropriate factor. The Agency
believes that these estimative procedures are readily defensible on firm
technical grounds. They have been demonstrated and presented in the open
literature in a peer-reviewed journal (4). A detailed description of the ECAO
methodology is provided in Appendix 6.
Results of the Chronic Toxicity Ranking— ECAO is evaluating a total of 245
hazardous substances. However, when the May 25, 1983, NFRM was published,
ECAO had completed the evaluation for only 64 of the 245, and only these 64
are being carried through to the final rule with a rating for chronic
toxicity. Ninety-seven of the remaining 181 appear in "Technical Background
Document to Support Rulemaking Pursuant to CERCLA Section 102, Volume 2,
(Proposed Rulemaking)," March 1985. The remaining 84 are also being evaluated
by CAG for potential carcinogenicity and will appear in a future rulemaking.
Additional discussion on potential carcinogenicity is provided later in this
document.
Of the 64 hazardous substances evaluated by ECAO, there were sufficient data
to assign an RQ to 42. The other 22 could not be ranked because of
insufficent data. The results on the 42 hazardous substances are given in
Table 2-7. ECAO has provided individual review documents for each of the 64
hazardous substances, which are available in the public docket. Individual

Note 3: Some hazardous substances have been ranked by analogy with other
hazardous substances, rather than by the direct application of the
methodology. (See the copper compounds in Table 2-7.) This process
is applied to hazardous substances which all contain the same metal
Ion, where the toxic effect Is known to be a function of that metal
Ion. Once a ranking has been established by direct application of the
methodology to one hazardous substance containing the metal ion, a
ranking can be derived for all other hazardous substances adjusting
for differences in the amount of metal ion present in the Individual
hazardous substance. This derivation process is known as ranking by
analogy.

reports on each hazardous substance, prepared for ECAO under a contract to
Syracuse Research Corporation, are on file. The composite scores for each of
the evaluated hazardous substances are provided in Tables 7-1, 8-1, and 8-2
under the column headed "CARC/CHRON."
Development of a Potential Carcinogenicity Ranking Procedure—
The, CAG is formulating a ranking methodology for assessing the CERCLA Section
101(14) hazardous substances identified as potential carcinogens. However,
the details of this methodology were not completely available for review at
the time the May 25, 1983, NPRM was published. Accordingly, all RQ
assignments based on potential carcinogenicity will be deferred to a separate
future rulemaking in order to allow an opportunity for internal Agency review
and for external review and comment. Hazardous substances identified as
potential carcinogens will remain at their statutory RQs pending this future
rulemaking.
Identification of Potential Carcinogens on the CERCLA Section 101(14) List—
In order to identify those CERCLA Section 101(14) hazardous substances which
should be the subject of a detailed potential carcinogenicity assessment by
CAG, lists of potential carcinogens were examined to ascertain the existence
of human epidemiological data and/or animal bioassay data which would be
indicative of possible carcinogenic activity. The sources of the lists of
potential carcinogens that were reviewed include the following:
1.	"First Annual Report on Carcinogens." This report was issued in July
1980 by the Department of Health and Human Services (DHHS). It was
prepared by the National Toxicology Program, U.S. Public Health
Services. It lists 26 substances, classes of substances, processes,
and byproducts which "have been reviewed by panels of international
experts and initially found to be associated with the induction of
cancer in man." This report was mandated under an amendment to
Section 301(b)(4) of the Public Health Service Act, Public Law
95-622, signed November 8, 1978.
2.	"Second Annual Report on Carcinogens." This report (December 1981)
was also issued by DHHS as required by the Public Health Service Act
(see 1, above). It lists 88 substances, classes of substances,
2-98
-------
processes, and byproducts which are "known human carcinogens and
substances which may reasonably be anticipated to cause cancer in
humans." All but one of the substances listed in the First Annual
Report were repeated in this Second Report (The one substance
dropped, chloramphenicol, is not on the CERCLA Section 101(14)
list).
3.	"Third Annual Report on Carcinogens" Summary. NTP 82-830. This
report (September 1983) is the third in the series by the DHHS, as
required by the Public Health Services Act. It lists 28 substances,
not identified in the two prior reports, which are "known
carcinogens" or "which may reasonably be anticipated to be
carcinogens."
4.	"Monographs Supplement 1. Chemicals and Industrial Processes
Associated with Cancer (IARC) in Humans." This report was issued
September 1979 by The International Agency for Research on Cancer.
It encompasses the results of a special working group established to
re-evaluate all prior IARC assessments to determine where studies
Identifying carcinogens met IARC's newer evaluation criteria. The
report lists 142 substances and classes of substances for which there
Is "sufficient evidence of carcinogenicity in experimental animals."
5.	"Monographs Supplement 4. Chemicals, Industrial Processes and
Industries Associated with Cancer in Humans." This report was issued
in 1982 by the IARC, and is essentially an updated version of
Monographs Supplement 1. This report lists 175 substances and
classes of substances for which there is "sufficient evidence of
carcinogenicity in experimental animals." It further evaluates the
risk to humans for a total of 154 chemicals, processes or industries.
The above lists were compared with the CERCLA Section 101(14) list to
determine which CERCLA Section 101(14) hazardous substances should be
evaluated by CAG. After a review by CAG, it was decided that all such
potential carcinogens would be included on the list to be evaluated,
regardless of whether other primary factors had already resulted in 1-pound
RQs. CAG wanted to include all such hazardous substances in order to test the
relative manner in which new or modified methodologies would rank them.
A total of 197 hazardous substances on the CERCLA Section 101(14) list were
thus identified aB potential carcinogens and submitted to CAG for a detailed
potential carcinogenicity assessment. Some of these hazardous substances are
2-99
-------
not specifically mentioned in the sources cited above, but were identified
because they are members of some particular class of chemical compounds. For
instance, the "First Annual Report on Carcinogens" lists arsenic and arsenic
compounds, cadmium and cadmium compounds, nickel and nickel compounds,
chromium and chromium compounds, and soots, tars, and carbon black, the latter
with the active agents identified as "polycycllc aromatic hydrocarbons." As a
result, all those CERCLA Section 101(14) hazardous substances which fell into
any of these classes were submitted to CAG for review and a detailed
assessment. However, CAG has determined that 12 of these hazardous substances
cannot be classified as potential carcinogens because of lack of substantive
evidence. These 12 hazardous substances have had new RQs proposed in the
report: "Technical Background Document to Support Rulemaking Pursuant to
CERCLA Section 102, Volume 2, (Proposed Rulemaking)," March 1985.
Other Factors For Adjusting RQs—
Certain of the RQs derived using the primary criteria evaluations in the
preferred adjustment methodology have been further adjusted using additional
considerations that reflect natural degradation processes which may reduce the
potential for harm from the release of a hazardous substance. These three
degradation processes are blodegradatlon, hydrolysis, and photolysis (BHP).
The RQ selected by assessing the primary criteria (mammalian toxicity, aquatic
toxicity, chronic toxicity, ignitability, and reactivity), is raised one level
(e.g., from 10 pounds to 100 pounds) if an analysis of these other factors
indicates that the substance degrades when released into the environment. The
use of these factors is based on scientific rationale and technical
information, as discussed immediately below, but the application of these
factors is not readily carried out in any multi-tier ranking scheme, so a
simple process of raising the RQ one level is used. The development of any
other more complex ranking scheme is not believed to be justified.
2-100
-------
The most important consideration in applying BHP is the understanding that it
is used for upward adjustment of RQs only if one or more of the three BHP
processes can result in the rapid degradation of a hazardous substance to a
less hazardous or non-hazardous substance or substances in the environment.
In cases vhere degradation of a hazardous substance results in the formation
of a new and different hazardous substance of similar hazard as the parent
hazardous substance, upward adjustments based on BHP are inappropriate* In
fact, the Agency has evaluated a number of substances which yield hazardous
degradation products, and for many of these, has determined that a downward
adjustment is more appropriate. These downward adjustment cases are described
separately in the discussion that follows.
Rationale for Incorporating BHP into the Adjustment Methodology — The use of
these other factors (BHP) to make final upward adjustment of RQs derived after
assessing the primary criteria is based on a number of considerations of which
the most important is the recognition that the major impact on the environment
of some hazardous substances is due to their degradation products rather than
to the substances released.
The BHP factors are processes occurring in the environment that are generally
termed, in the aggregate, "fate and effects." The deregulatory use of fate and
effects data has precedent in various prior Agency regulations and guidelines.
For instance, in determining the Ambient Water Quality Criteria for Chloralkyl
Ethers (5), no criteria were established for chloromethyl methyl ether because
"such standards would be of academic Interest only...due to extremely short
half-life in aqueous solution" (i.e., rapid hydrolysis). However,
chloromethyl methyl ether is currently being evaluated for its ranking as a
potential carcinogen, and the application of BHP adjustments to potential
carcinogens is subject to further review.
2-101
-------
It should also be noted that RCRA takes degradation Into account, and provides
for eliminating substances from the hazardous waste lists if there Is
"potential for the constituent....to degrade Into non-harmful constituents..."
(40 CFR Section 261.11(a)(3)(v)).
The use of BHP factors also provides a degree of technical balance in the
Agency's approach to long-term effects. As noted earlier, even though the
Agency intends to focus its enforcement activities on episodic releases, it
still intends to use long-term effects (i.e., chronic toxicity) as primary
criteria because CERCLA covers both episodic and continuous releases, and
because episodic releases which are not completely cleaned up may result in
repeated or continuous exposure to a hazardous substance. The BHP factors
represent the technical counterpoint to this position. That is, a hazardous
substance subject to BHP is essentially self-decontaminating, so that residues
will not persist and be a source of repeated or continuous exposure. Taking
into technical account both the negative and positive aspects of a hazardous
substance's properties thus reduces the possibility that the use of primary
criteria representing long-term effects (i.e., chronic toxicity) will be
challenged as arbitrary.
Finally, as mentioned earlier, applying the primary criteria already includes
provisions which would allow for downward adjustments if the risk posed by the
release of a hazardous substance is increased as a result of BHP (i.e., if the
natural degradation processes produce hazardous substances in the environment
that are more hazardous than the original hazardous substance released). The
Agency has taken the nature of degradation products into account wherever
appropriate both during this present effort, and in the designation of
hazardous substances under prior statutes. For instance, under the CWA
Section 311, and/or the CWA Section 307(a), the breakdown products of DDT,
namely DDE and DDD, were also designated, and all are currently undergoing
evaluation as potential carcinogens. Similarly, both heptachlor and its
degradation product, heptachlor epoxide, were designated under the CWA Section
2-102
-------
311 and the CWA Section 307(a), respectively, and are being evaluated as
potential carcinogens. These are cases where the metabolites (products of
biological breakdown) are believed to be at least as toxic as the parent
hazardous substances.
In the present study, ten hazardous substances have been evaluated for RQ
assignment as special cases of the reactivity criteria, namely that they yield
toxic degradation products upon hydrolysis, as given in Table 2-8. These ten
hazardous substances are ones known to yield other hazardous substances,
namely hydrofluoric acid, hydrogen sulfide, or phosphine, upon degradation by
hydrolysis. The ten original hazardous substances are treated as falling into
a special category of reactivity, and each is assigned a reactivity RQ equal
to the RQ of the degradation hydrolysis product. Consideration of the
degradation products thus has already resulted in lower RQs for two of these
hazardous substances, and may result in lower RQs for five others, depending
on the results of chronic toxicity evaluations. For three other hazardous
substances the RQ from the other primary factors is the same as the reactivity
RQ based on the degradation product.
In addition, four hazardous substances are undergoing evaluation for potential
carcinogenicity, on the basis of degradation products which are potential
carcinogens. These hazardous substances are phenyl dichloroarsine,
diethylarsine, and cacodylic acid, all of which can yield potential
carcinogenic inorganic arsenic oxide upon degradation, and chloral
(trichloroacetaldehyde) which has chloroform, a potential carcinogen, as a
hydrolysis product.
The Single-Level Adjustment Process Using Other Factors— The three
degradation processes of BHP tend to reduce the relative potential for harm to
public health and welfare and the environment of certain hazardous substances
if they are released. Using BHP to adjust RQ values takes the environmental
fate characteristics of particular hazardous substances into account, and
allows for an overall reduction in reporting burden while still adequately

-------
protecting public health and welfare and the environment. However, while
their application is based on technical data and a suitable rationale in the
opinion of the Agency, they are not amenable to a multi-tier ranking scheme
for several reasons. As one consideration, any such tiered ranking scheme
would obviously have to place in its lowest level, (i.e., worst effect) those
hazardous substances that do not undergo BHP. Hazardous substances that do
not undergo BHP include "refractory" organic compounds (i.e., organic
compounds, which for one reason or another, persist in the environment after
their release) and all Inorganic compounds. Since neither of these types of
hazardous substances undergo BHP, such a scheme would automatically force all
refractory organic and inorganic hazardous substances into the lowest
assignable RQ. For example, osmium oxide, currently assigned an RQ of
1000 pounds on the basis of mammalian toxicity, would be reduced to the lowest
possible RQ level (presumably one pound) with a 5-tier BHP scheme. However,
while it is evident that the potential for harm for a hazardous substance
undergoing BHP does indeed decrease as it degrades, it does not follow that
the potential for harm of an inorganic hazardous substance such as osmium
oxide increases simply because it doesn't degrade. The only way around such
an automatic low ranking for refractories and inorganics would be to either
establish a tiered ranking system that did not use the lowest possible RQ
levels, or to exempt such hazardous substances from consideration entirely.
However, no justification for either of these approaches is readily evident.
A future consideration, which could conceivably avoid the problem of
automatically placing all non-degradable hazardous substances at the lowest
value in a multi-tier BHP ranking scheme, would be to combine BHP and primary
criteria in some compensatory fashion that allowed them to "average" out. For
instance, in the osmium oxide example, one might allow the 1000-pound primary
criteria RQ and the hypothetical 1-pound BHP RQ to "average out" at the
10-pound or 100-pound RQ level. However, this is tantamount to creating a
hazard index based on combining the primary criteria and BHP in some additive
fashion. The Agency has rejected the hazard index approach as unworkable due
to lack of needed data. (See Appendix D for additional discussion). In the
2-105
-------
case of osmium oxide, one of the problems inherent in hazard indices becomes
evident, namely, that there is no objective way to assign weights
(coefficients) to the different factors being combined. In combining BHP and
the primary criteria in this hypothetical case, the final combined value would
be 10 pounds if the BHP factors are given the greater weight, but would be
100 pounds if the primary criteria are given the greater weight. There is no
way to decide which of these two values is the appropriate one to use.
The primary criteria are based on certain inherent negative characteristics of
hazardous substances, including degradation to other hazardous substances.
The BHP factors are also based on inherent characteristics (the potential for
degrading by various mechanisms) which serve to counteract the negative
aspects. On this basis, it is reasonable to take the BHP factors into account
in assigning RQs whenever a sound technical basis can be used to do so.
However, since a multi-tier RQ scheme does not appear to be feasible for BHP
the Agency feels that a simple one level upward adjustment is sufficient. The
decision to adjust one level upward carries the proviso that in order to do so
there must be good technical evidence that degradation can indeed occur for
any substance selected for adjustment.
Technical Basis for BHP Adjustment— 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.
Many compounds, especially organlcs, can be biologically degraded into less
complex chemicals over time, either by natural or artificially Induced means,
and precedents for using biodegradation to clean up hazardous substance spills
exist. Hydrolysis, on the other hand, Is a chemical reaction resulting from
the addition of water that splits a bond between chemical units, and that
introduces a hydroxyl group (-0H) into the chemical structure (i.e.,
RX + H2O —> ROH + HX). And finally, photolysis is a process that occurs when
a chemical (either dissolved in aquatic systems or present in the atmosphere)
absorbs sunlight and then undergoes an energy transformation by any one of
several mechanisms (e.g, dissociation, rearrangement, or oxidation). Under
2-106
-------
all three processes a hazardous substance may be degraded Into less hazardous
or relatively Innocuous products.
The processes that have been considered for upward adjustment of RQs are
limited to the degradation processes of biodegradation, hydrolysis, and
photolysis. Transport processes such as volatilization (see later discussion)
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 hazardous
substance from sorption-desorption equilibrium and the hazardous substance in
solution can be transferred to the air medium by volatilization.
However, it is recognized that transport processes can play an important role
in that they can affect the susceptibility of hazardous substances to the BHP
processes. For example, since biodegradation occurs only in the soil and
water media, not in the air, a highly volatile hazardous substance cannot be
considered a candidate for biodegradation unless some additional mechanism,
such as high water solubility, prevents its escape to the atmosphere. This
subject is discussed at more length under the heading Biodegradation,
immediately below.
Biodegradation — Biological oxygen demand (BOD) data were used to determine
whether or not biodegradation is an important mitigating process in assessing
the environmental fate of the CERCLA hazardous substances. The specific
criteria that were applied in evaluating BOD data to determine if a particular
hazardous substance should have its primary criteria RQ raised one level on
the basis of its biodegradability are as follows. If the reported BOD^ value
(5-day test at 20°C) is equal to or greater than 50% of the theoretical oxygen
demand, a hazardous substance is considered to be sufficiently biodegradable
2-107
-------
to warrant upward RQ adjustment. (The theoretical oxygen demand is the
stoichiometric quantity of oxygen required to oxidize a substance completely
to carbon dioxide and water. The percent theoretical oxygen demand is the
ratio* of the observed test results to the calculated demand.) For example,
the reported BOD,, value for acetic acid is 76% theoretical. Based on this
data, acetic acid was judged to be sufficiently biodegradable to merit an
adjustment of its primary criteria RQ from 1000 pounds (based on aquatic
toxicity) to 5000 pounds (see Table 7-1).
Application of Biodegradatlon to Highly Volatile Substances. Biodegradation
occurs in the soil and water media, but not in the atmosphere. However, the
BOD^ test used as a factor in upward adjustment of RQs is conducted in a
closed container, which prevents volatile substances being tested from
escaping into the atmosphere. Thus a highly volatile hazardous substance
might be readily biodegraded in the BOD^ test, but in an actual release, it
might escape to the atmosphere so rapidly that biodegradation could not occur.
The Agency has accordingly elected not to apply the biodegradation RQ
adjustment to any hazardous substance which is highly volatile, unless that
hazardous substance is also highly water soluble. Substances which are highly
water soluble will be retained in both the water medium and by soil moisture.
Although it is not an absolute measure of volatility, the Agency will use a
boiling point criterion to decide which hazardous substances are highly
volatile. For this purpose, the boiling point of 100°F has been selected,
with substances boiling at 100°F or less considered highly volatile. The
100°F point is one of the same points used in distinguishing between the RQ
level based on ignitability, and is derived from its use by the National Fire
Protection Association (NFPA) to classify flammable liquids into various
hazard classes where volatility is a factor.
2-108
-------
Only one candidate for BHP adjustment, acetaldehyde, has a boiling point of
less than 100°F. However, this hazardous substance is also highly water
soluble, (infinitely miscible) so an adjustment based on biodegradation has
indeed been applied to it.
Hydrolysis and Photolysis— In addition to biodegradation, the processes of
hydrolysis and photolysis were evaluated to determine if a particular
hazardous substance should have its primary criteria RQ further adjusted.
The decision to actually apply these criteria in the final adjustment of RQs
for certain hazardous substances is based on either specific half-life data
reported in the literature or on statements made in the literature relative to
the ability of the hazardous substance to hydrolyze or photolyze with a
half-life of five days or less. (A half-life is an estimate of the
environmental persistence of a chemical or the time required for removal of
one-half of the initial amount, or concentration, of the chemical).
For several hazardous substances specific half-life data could not be found.
However, general statements about the ability of the hazardous substance to
hydrolyze (or photolyze) were evaluated along with BOD data for the substance
itself or its hydrolysis products, to determine if the primary criteria RQ
could be raised based on a combination of evidence. For example, the
hazardous substance acetic anhydride is known to react instantaneously with
water (hydrolyze) to yield acetic acid, which is also a CERCLA hazardous
substance. The BOD^ for acetic acid is 76% theoretical and acetic acid is
therefore considered biodegradable. This combination of evidence was thus
used to raise the primary criteria RQ of acetic anhydride from 1000 pounds to
5000 pounds. The overall process, even though it was based on a combination
of several different BHP factors, was still deemed to be sufficient for
raising the RQ of acetic anhydride by one level.
2-109
-------
Method of Applying the BHP to the CERCLA Section 101(14) List— The process of
selecting candidate hazardous substances for evaluation and possible upward
adjustment involved first applying a series of elimination criteria to the
entire CERCLA Section 101(14) list, and considering any hazardous substance
not eliminated as a candidate for BHP adjustment. All hazardous substances
with RQs already proposed at 5000 pounds were eliminated. Under the five-tier
notification system, 5000 pounds is the largest RQ that can be assigned for
these hazardous substances. In addition those hazardous substances still
under assessment for potential carcinogenicity were eliminated until such time
as their assessments can be completed.
After the above elimination process had been carried out, there was left an
initial candidate list of hazardous substances which was then assessed for
evidence of BHP. At the same time each hazardous substance was assessed to
determine If it should be dropped from consideration for any one or a
combination of the following factors: (a) biodegradation not pertinent (i.e.,
hazardous substance is not a carbon source), (b) evidence of bioaccumulation,
(c) hazardous substance resists degradation or is persistent, (d) hazardous
substance is highly inhibitory to microbes and not amenable to biological
treatment at municipal sewage treatment plants, (e) hazardous substance
presents unusual hazards (i.e., dangerously reactive, poisonous gas), and (f)
hazardous degradation or transformation products are generated. These last
hazardous substances are subject to having their RQs lowered on the basis of
their hazardous product. (See earlier discussion on the reactivity criterion
assessments.)
Evidence concerning BHP was drawn from the evaluations documented In a series
of references (6, 7, 8, 9, 10, 11), although it should be noted that data from
one of these references (8) was not included until it was identified by a
commenter. (See discussion on p. 2-116.)
2-110
-------
For many of the hazardous substances designated on the CERCLA Section 101(14)
list, the predominant process or processes and the importance of these
processes cannot be identified at all or even with any reasonable degree of
certainty because of a lack of data. Hydrolysis and photolysis data which
have been estimated by various researchers using theoretical methods are
available for certain hazardous substances; however, these data have not been
confirmed and were not used in this application.
Appendix C summarizes the results of this review for the candidate hazardous
substances. It lists the BOD, hydrolysis, and photolysis data that were
available, identifies those hazardous substances rejected on the basis of
bioaccumulation, persistence, reactivity, or hazardous degradation products,
and Indicates those hazardous substances for which no data or insufficient
information were available to make an evaluation. Table 2-9 presents the
final candidates, 27 in number, for which sufficient data are available to
justify upward RQ adjustments of one level on the basis of BHP. The majority
of the candidates were selected because of biodegradability. Also shown in
the table are the original RQ assignments derived using the primary criteria
and the basis on which those assignments were made. The net effect of
applying BHP data is as follows:
Volatility Not Used as an Additional RQ Adjustment Factor— As discussed
earlier, the volatility of hazardous substances is taken into account in
deciding whether a hazardous substance's RQ should be adjusted based on
biodegradation. Some consideration was also given to the possibility of using
volatility itself (or more generally, dispersibility) to adjust RQs upward.

As noted in the May 25, 1983 NPRM preamble, EPA considered using volatility
(the process by which a hazardous substance vaporizes into the air) as an RQ
adjustment factor, but had rejected it because the hazard posed by a release
of a hazardous substance does not necessarily decrease when the substance
moves from soil or water into the air.
It might be argued that a volatile hazardous substance would rapidly dissipate
into the atmosphere and cease to present any hazard or at least not be
susceptible to any response. This argument tacitly assumes a particular
scenario or set of circumstances, namely, that the hazardous substance be
released quickly into a non-confining area where turbulent wind conditions
would lead to its rapid dispersion. However, it is also possible to have
conditions where a hazardous substance is released slowly, where the terrain
or nearby structures may confine the hazardous substance, and when the air is
quiescent. Under these conditions, the hazardous substance would remain in
the area as an expanding cloud. The fact is that releases of volatile
hazardous substances, such as chlorine, have resulted in documented cases of
serious injuries and deaths under circumstances such as these latter ones.
The Agency has no way of predicting the circumstances that may surround any
future release of any volatile hazardous substance, and thus should not adjust
RQs to favor a particular set of conditions. As stated earlier, the RQs are
intended to be triggers for notification, and RQs cannot be specifically
designed to account for all factors inherent in the circumstances of release
conditions. While it may be true that under some conditions, where a
hazardous substance is particularly volatile, no response action may be
feasible, this does not affect the Agency's position that the movement of a
hazardous substance between environmental media does not necessarily affect
the potential hazard. The feasibility of a response is a decision for the
OSC.
Changes in the Final Rule Based on Comments About BHP— Many of the commenters
who support the use of BHP have at the same time asked the Agency to consider
specific technical ideas offered to clarify and broaden the scope and
2-114
-------
application of these criteria. Two such comments have resulted in changes
from the NPRM.
1. Application of Other Criteria to Chronically Toxic Substances
The NPRM noted that BHP was not used to raise RQs based on chronic
toxicity and did not mention the application of BHP to hazardous
substances being evaluated for potential carcinogenicity. Several
commenters expressed the opinion that BHP should be applied to those
hazardous substances which have already been evaluated for chronic
toxicity and those which are currently being evaluated for potential
carcinogenicity. They noted that the processes of BHP may in certain
cases reduce the potential hazard of such hazardous substances. The
Agency agrees that BHP should be applied to those hazardous
substances evaluated for chronic toxicity. However, the application
of BHP to potential carcinogens is still under review.
The Agency has now used BHP to adjust RQs of two hazardous substances
that were evaluated for chronic toxicity. Table 2-10 lists the two
hazardous substances evaluated for chronic toxicity that have had
their primary criteria RQs increased one level on the basis of
biodegradation.

2. Additional Data Resource Review and Use
One commenter recommended the following data source on
biodegradability:
Ludzack, F. J. and Ettinger, M. B., "Chemical Structures
Resistant to Aerobic Biochemical Stabilization," 14th Annual
Purdue Industrial Waste Conference, Lafayette, Indiana, May 5-7,
1959.
This source contained quantitative biodegradation data on a number of
substances, of which 34 were CERCLA hazardous substances. Nineteen
of these had BOD^ values of at least 50% of theoretical, the
criterion of biodegradation for the purposes of BHP adjustment. Of
these 19, the RQs of eight had already been adjusted upwards on the
basis of BHP, four were already at the maximum RQ level of
5000 pounds and therefore could not have their RQs raised any
further, and five were still being assessed for potential
carcinogenicity and/or chronic toxicity. Data provided in this
reference on the remaining two hazardous substances indicates that
their RQs could be raised. Accordingly, the RQs for these two,
furfural and acetonitrlle, are being adjusted to 5000 pounds from
their previous 1000-pound RQs. These new RQs will appear in the
final rule. Note that acetonitrlle had originally been assigned its
RQ on the basis of chronic toxicity. Its upward adjustment was
mentioned earlier (see Table 2-10).
An additional source of information related to other criteria which
has not been reviewed was also recommended. This is the
Environmental Fate Data Base of the Syracuse Research Corporation,
which reportedly contains environmental fate information on at least
500 substances as well as abstracts and references to information in
the published literature. This is a privately owned data base, and
it was not available when the May 25, 1983 NPRM was being prepared.
The commenter who suggested its use did not offer to make it
2-116
-------
available.
Changes in the Final Rule Based on Restrictions in Applying BHP — In its
original review of the literature for data on BHP, the Agency collected and
applied data on biodegradation and hydrolysis that involved test periods of
greater than five days. Specifically, 20-day biodegradation test data (BOD^q)
and 30-day hydrolysis half-lives were used to make upward RQ adjustments for
four hazardous substances in the Hay 25, 1983 NPRM. These four hazardous
substances are allyl chloride, butylamine, diazinon, and ethyl acrylate. The
Agency has since decided to apply BHP adjustments to RQs strictly in
accordance with the 5-day criterion stated earlier, to ensure that all
hazardous substances selected for the one-level Increase will tend to degrade
rapidly once they are released. Therefore, the four hazardous substances will
be assigned their primary criteria RQs in the final rule, as follows: allyl
choride, 1000 pounds; butylamine, 1000 pounds; diazinon, 1 pound; ethyl
acrylate, 1000 pounds.
Summary of the Merits of the Preferred RQ Adjustment Methodology—
The preferred methodology outlined above for RQ adjustments to the CERCLA
Section 101(14) list is considered appropriate for the following reasons:
1.	For each hazardous substance, it focuses on the dangerous property of
greatest concern;
2.	Much of the data required for its application are available;
3.	It can provide for further adjustments based on comments, new data,
and considerations of administrative feasibility;
4.	It uses established procedures for arriving at RQs (i.e., the CWA
Section 311);
5.	It permits emphasis on the appropriate medium (air, water, soil)
without being media-specific;
6.	It permits maximum flexibility;
7.	It minimizes arbitrariness.

UNLISTED HAZARDOUS WASTES
Ignitable, Corrosive, and Reactive (I,C,R) Hazardous Wastes
The RQ of an undefinable number of unlisted hazardous wastes that exhibit the
characteristics of ignitability, corrosivlty, and reactivity (I,C,R), as named
in subpart D of RCRA, have been adjusted to 100 pounds. The Agency has
determined that the I, C, R components present in the hazardous wastes will,
on average, fall within the middle tier of the five-tier ranking system. The
Agency has made this determination by examining the RQs of many known
hazardous wastes that could fit these classifications, and finding that
approximately equal numbers fall above, below, and at the 100-pound RQ level-
Accordingly, they are assigned 100-pound RQs.
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 (corrosivlty Is not one of the primary criteria; see further discussion
below). The RQ assigned most often for hazardous wastes on the basis of
reactivity is ten pounds. The RQ assigned most often for hazardous wastes on
the basis of ignitability is 1000 pounds. Accordingly, unlisted hazardous
wastes that are reactive have been assigned an RQ of ten pounds, while
Ignitable unlisted wastes have been assigned 1000-pound RQs. The Agency
believes that under this alternate approach, the selected RQ may not
adequately reflect the characteristics inherent in a hazardous waste. An
unlisted hazardous waste is often a mixture of hazardous wastes that may
exhibit more than one of the unlisted hazardous waste characteristics, and
thus it may not be appropriate to base the assigned RQ on one particular
characteristic. Therefore, the 100-pound RQ assignment on all unlisted
hazardous wastes Is preferred.
2-118
-------
Although the Agency is assigning an RQ to unlisted corrosive hazardous wastes,
the Characteristic of Corrosivity was not used as a primary ranking criterion
in assigning RQs by the preferred 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.
NAS (1) developed a five-tier scale for "Health (Corrosivity, Skin and Eyes)."
(See Table 2-4.) However, examination of the NAS scale shows that it is a
mixture of such criteria as "corrosive to skin" and "corrosive to eyes," and
dermal toxicity LD,.q values for 24-hour skin contact. Dermal toxicity has
been treated in a more appropriate fashion as one aspect of mammalian toxicity
under the primary criteria.
The RCRA regulations define the Characteristic of Corrosivity in terms of pH
ranges and rate of attack on steel (40 CFR Section 261.22, 45 FR 33122, and
46 FR 35247), choosing the former "because wastes exhibiting low or high pH
can cause harm to human tissue," among other things (45 FR 33109). In effect,
the pH scale used by RCRA has only two levels:
Corrosive: pH > 12.5 or < 2.0
Noncorrosive: pH 12.5 to 2.0
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
2-119
-------
aqueous systems. Furthermore, some hazardous substances may be irritating or
corrosive to human tissue via mechanisms other than attack by acids or
caustics.
Corrosivity to animal tissue can be evaluated using a protocol known as the
Draize test. 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 Commission version of these tests (16 CFR Sections 1500.41 and
1500.42) 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 common being
whether or not the test area is left open to the air or covered during the
test period. Trying to develop a multi-tier RQ scale on the basis of these
tests proved to be impractical because the numerous variations did not lend
themselves to a consistent ranking process. Furthermore, numerical data' are
very sparse. For 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 hazardous waste lists shows that only five hazardous
wastes have been listed as exhibiting corrosivity, and none has been listed
exclusively because of corrosivity. These hazardous wastes are as follows:
U006 Acetyl chloride (corrosive, reactive, toxic)
U020 Benzenesulfonyl chloride (corrosive, reactive)
U023 Benzotrichloride (corrosive, reactive, toxic)
U123 Formic acid (corrosive, toxic)
U134 Hydrofluoric acid (corrosive, toxic)
2-120
-------
Accordingly, it was decided that developing a corrosivity ranking scale would
be deferred, and that if it seemed warranted the five hazardous wastes 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
hazardous wastes appears to be satisfactory, and is as follows:

Extraction Procedure (EP) Toxic Wastes
The Characteristic of EP Toxicity was designed to identify hazardous wastes
that would likely contribute to contamination of groundwater by leaching from
landfills. There are currently only 14 substances for which the EP toxicity
characteristic can be determined, as listed in 40 CFR Section 261.24. Six of
these are specific hazardous substances (pesticides and herbicides), and RQs
for these can be assigned based on the specific hazardous substances. RQs for
these pesticides and herbicides may be taken from the values already
determined for these hazardous substances in Tables 7-1 or 8-1, and are
displayed in Table 2-11.
The other eight hazardous substances, however, while nominally listed as the
metal, must actually be determined on the basis of some soluble compound of
that metal. Carrying out the EP toxicity test dictates that a soluble species
containing the specified metal cation must be determined to be present in the
waste. The RQs are those corresponding to the CWA Section 311 RQs of the
corresponding water-soluble salts when available (i.e., for mercury and
silver). The RQ of barium is derived from the fact that the TL -96 of barium

RQs FOR THE F AND K WASTE STREAMS
Table 8-2 lists the waste-stream hazardous substances from RCRA regulations
40 CFR Sections 261.31 and 261.32. These are commonly called the "F" and "K"
waste streams, referring to the prefix used in the EPA's identifying hazardous
waste numbers.
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 is
wastewater treatment sludges from electroplating operations). The RCRA K
waste streams are hazardous wastes from specific sources (e.g., K060 is
ammonia still lime sludge from coking operations). In order to assign RQs to
these waste streams, the EPA has first examined the hazardous constituents in
each F and K waste stream (i.e., 40 CFR Part 261, Appendix VII). The next
step has been to identify the RQs associated with each constituent and then
assign an RQ to each waste stream. The final RQ of the waste stream Is the
lowest RQ associated with the individual constituents of the waste stream.
MIXTURE RULE
When determining if notification is required for releases of mixtures and
solutions containing hazardous substances, the May 25, 1983 NPRM (48 FR 23555)
noted the Agency's intention to apply the CWA Section 311 mixture rule. This
rule is discussed in the preamble to the rulemaking for 40 CFR Part 117, and
states that "[d]ischarges of mixtures and solutions are subject to these
regulations only where a component hazardous substance of the mixture or
solution is discharged in a quantity equal to or greater than its RQ."
(44 FR 50767, August 29, 1979.) RQs of different hazardous substances are not
additive under the mixture rule. Thus, a release of ten pounds of solution X
2-123
-------
which contains one pound of hazardous substance A and nine pounds of
nonhazardous substance B is not reportable if the RQ of hazardous substance A
is ten pounds. Furthermore, a 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 the rulemaking for 40 CFR Part 117, it is not valid to assume that
the toxic properties of all different hazardous substances can be considered
additive.
The Agency takes the view that additivity does not hold for the large majority
of cases, and there is very little additional threat to the environment,
public health, and welfare resulting from overlooking those circumstances
where additivity does occur. Unless the hazardous substances are very closely
related, additivity in toxic effects is not readily predictable from a
knowledge of the toxic effects of the individual components of a mixture.
Each system will differ in an unpredictable manner. Only a large program of
testing could possibly show the true additivity of mixtures, and all
concentrations of all mixtures could not be addressed due to the sheer
magnitude of such a program and its extreme cost. Many factors can affect how
two or more hazardous substances will act together in biological systems.
Among these are the target organs, the mode of action on those organs, the
nature and activity of both the hazardous substance and of its metabolites,
detoxification mechanisms, excretory routes, relation of doses to thresholds,
and many others.
The Agency recognizes that certain mixtures have effects which may be
additive. These include mixtures of flammable substances, mixtures of
reactive substances, and mixtures of toxic substances where the toxic effects
are related to some common constituent of each component of the mixture. For
instance, a 100-pound mixture consisting of 50 pounds of lsoprene
(RQ = 100 pounds, based on ignitability) and 50 pounds of chloroethane
(RQ = 100 pounds, based on ignitability) still represents the same
ignitability hazard as 100 pounds of either one of its components alone.
2-124
-------
Similarly, mixtures of oxidizers, mixtures of explosives, and mixtures of
water-reactive substances, or of reactive substances with potential for
releasing the identical toxic gas (e.g., metal sulfides) also represent cases
where it may be appropriate to apply additivity.
Additivity does not apply, however, to the large majority of releases
involving CERCLA hazardous substances. CERCLA RQs are based on six diverse
primary criteria (some of which are simply not additive) along with
adjustments for BHP so that most mixtures contain components that are
hazardous for different reasons, making the use of additivity Illogical.
Thus, for most mixtures, the result of conducting any sort of detailed
analysis would be to prove that additivity should not be applied. Moreover,
applying an additivity rule would make the determination that an RQ had been
released much more complex. A releaser would have to determine the exact
composition of a mixture, in terms of all the hazardous substances present and
their exact concentrations, to determine whether the release equalled or
exceeded an RQ. This would put a burden on the regulated community far beyond
the requirements of any similar regulatory program. For these reasons, the
Agency will apply the CWA mixture rule — contained in Section 302.6 of the
final rule — to CERCLA hazardous substances.
An alternative approach would be to apply the RQ to the mixture or solution as
a whole. Under this approach, a release of ten pounds of solution X which
contains one pound of hazardous substance A and nine pounds of nonhazardous
substance B would be reportable, if the RQ of the hazardous substance A was
ten pounds. 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 RCRA approach to additivity was
not adopted because it is too complex and 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 assigned RQ.
2-125
-------
Use of The CWA Mixture Rule - Application to Waste Streams
The Agency maintains that if the concentrations of the hazardous substances
contained in the mixture are known, waste streams should be treated like any
other mixture. If the releaser does not know the composition of the listed
waste stream, he should apply the RQ of the entire waste stream. For example,
consider the mixture of spent (used) cresols and/or nitrobenzene, and/or still
bottoms from their recovery. This hazardous substance mixture is also
identified in the RCRA regulations (40 CFR Section 261.31) as a hazardous
waste from a non-specific source, F004. The RQ for cresols is 100 pounds and
the RQ for nitrobenzene is 1000 pounds. Therefore, the RQ of F004 is
100 pounds since the lowest RQ for any of the hazardous substances in the
mixture applies. If someone were to release a quantity of this hazardous
substance, and all he knew about it was that it was a waste material
containing unspecified amounts of cresols and/or nitrobenzene, then he would
have to report if 100 pounds or more were spilled. In other words, if all he
knows is that he is dealing with a hazardous substance that can be identified
only by the classification of "F004 Waste," then he must report when his
release exceeds the 100-pound RQ that has been established for F004 waste.
Since he does not know the composition of the hazardous waste stream, applying
the RQ determined just for that hazardous waste stream is the only feasible
alternate.
The CWA mixture rule, as adopted under CERCLA, does not require the regulated
community to analyze for releases or to conduct tests beyond those
requirements currently imposed by RCRA. However, the releaser has the option
to test for specific components if he so chooses, and if it appears to be to
his advantage he can characterize his hazardous waste so he can apply a more
specific RQ. Suppose the releaser makes the investment to analyze the F004
waste and finds that because of his particular process, the waste contains 50
percent cresols and 50 percent nitrobenzene. The releaser would have to
report only when the total release equalled or exceeded 200 pounds, because at
2-126
-------
that point the 100-pound RQ of the cresol component would be equalled or
exceeded. Because the concentrations of the hazardous substances In the waste
stream are known, there is no reason to restrict the releaser to the F004
waste RQ of 100 pounds. In this case, for notification purposes, the waste
stream is no different than a known mixture of pure substances.
From the Agency point of view, it would always be better if the exact
composition of any released mixture were known, since exact knowledge of the
composition would allow the Agency to plan its response or remedial action
more soundly. Again, note that the Agency does not require any testing of
waste streams under CERCLA beyond that currently specified by RCRA
regulations.
BROAD GENERIC CLASSES
Table 2-1 contains many broad, generic classes of organic and metallic
compounds designated as toxic pollutants under the CWA Section 307(a), such as
"chlorinated phenols," "phthalate esters," and "zinc and compounds." Many of
the broad, generic classes of compounds encompass innumerable specific
compounds. Consequently it would be virtually impossible for the Agency to
develop a reportable quantity for a generic class of compounds which would
take into account the characteristics of all of the specific compounds, each
with different characteristics. Therefore, only those specific compounds
designated as hazardous substances in implementing the CWA Sections 307(a) or
311 are included in Table 2-1, and iw adjusted RQ is assigned for the broad,
generic classes. The notification requirements apply to those specific
hazardous substances for which RQs are listed in Table 2-1, rather than to the
generic listings. This does not, however, preclude liability with respect to
releases of hazardous substances which are within one of these generic
listings but which are not listed in Table 2-1 for reporting purposes.
2-127
-------
Most of the broad generic classes listed under CWA Section 307(a) contain
members with widely differing toxicity and so no RQ is listed for them. RQs
have been or will be adjusted for the three narrow generic classes— PCBs,
cyanides and coke oven emissions— all of whose members have quite similar
characteristics.
DIFFERENCES BETWEEN FINAL RULE RQs AND MAY 25, 1983 NPRM RQs
Sixty-four (64) individual hazardous substances, two unlisted hazardous waste
constituents, and 13 listed specific and non-specific hazardous waste streams
have RQs in the final rule that have been changed from those proposed in the
May 25, 1983 NPRM. The hazardous substances and hazardous waste streams,
along with the reasons for making the RQ changes, are outlined in Table 2-12.
More detailed discussions of these changes follow.
Hazardous Substances on the CAG List not Identified as Potential Carcinogens
in the NPRM
The 23 hazardous substances (listed in Table 2-12, outline topic I-A) are all
potential carcinogens, based on the references cited earlier in this document
as the sources for identifying potential carcinogens. In developing the
potential carcinogen list for evaluation by CAG, it was noted that other
primary criteria had already established 1-pound RQs for these hazardous
substances. Since additional ranking based on potential carcinogenicity could
not result in any lower RQs, it was originally considered to be unnecessary to
Identify them further, and 1-pound RQs were proposed in the May 25, 1983 NPRM.
However, in order to fully develop and test the methodology that CAG now has
under consideration for ranking potential carcinogens, it has now been deemed
necessary to include and evaluate all potential carcinogens, regardless of
what the results of applying other criteria might be. Accordingly, statutory
RQs for these 23 hazardous substances are not changed in the final rule,
pending the completion of CAG's methodology development and RQ assignment on
2-128

-------
the RQ of the overall waste stream Itself, since the waste
stream still requires an evaluation of Its other components
prior to a final RQ assignment.
2-133
-------
the basis of potential carcinogenicity.
Polychlorinated Biphenyls (PCBs)—
Included among the 23 potential carcinogens listed above are the general class
of PCBs, as well as seven specific hazardous substances known by their trade
name of Aroclor that fall into the PCB category. The Agency proposed to lower
the RQ for PCBs to one pound from the original CWA Section 311 statutory value
of ten pounds. The lower RQ was based on more recent aquatic toxicity data.
The Agency acknowledged that because of the ubiquitous use of PCBs, it was
concerned with the increased number of notifications that might result from
the proposed reduction of the PCB RQ. The Agency has since decided to defer
any promulgation of a final PCB RQ until a future rulemaking. The Agency is
currently evaluating PCBs for potential carcinogenicity to determine whether
the RQ should be based on this primary criterion, and the statutory RQ of ten
pounds will remain in effect until a final RQ is promulgated for PCBs.
Hazardous Substances Newly Identified as Potential Carcinogens
In the earlier discussion on the identification of potential carcinogens, five
documents were listed as the sources of such identification. Two of these,
the IARC "Monographs Supplement 4., Chemicals, Industrial Processes, and
Industries Associated with Cancer in Humans," and the DHHS "Third Annual
Report on Carcinogens" were not available until after Table 302.4 had been
prepared for publication in the May 25, 1983 NPRM. Reviewing these references
resulted in identifying five potential carcinogens in the CERCLA Section
101(14) list that had not been previously identified. The RQs of three of
these hazardous substances (listed in Table 2-12, Outline Topic I-B) will
accordingly remain at their statutory value, pending the potential
carcinogenicity ranking by CAG. The fourth and fifth hazardous substances,
formaldehyde and sulfur selenide, were already listed in the NPRM at their
statutory RQs because they were already undergoing evaluation for chronic
toxicity.
2-134
-------
Substances Where a Change Occurred as a Result of Peer Review of Relevant Data
All ECAO rankings of hazardous substances for chronic toxicity, and all of
CAG's work on the development of a ranking method for potential carcinogens
have been through a series of internal and external peer reviews. In the
early stages of the CAG development effort, a number of the potential
carcinogens were not ranked, and it was stated that "other toxicity components
must be used as the basis for ranking." This is tantamount to stating that
there is no substantive evidence that such hazardous substances are potential
carcinogens, and accordingly such hazardous substances were assigned RQs and
listed in the NPRM on the basis of other primary criteria. However, as the
development work has progressed, and with refinements resulting from peer
review, six such hazardous substances have been found to be potential
carcinogens after all. These six hazardous substances (listed in Table 2-12,
outline topic I-Ca) accordingly will retain their statutory RQ pending their
final potential carcinogenicity ranking.
Similarly, five other hazardous substances being evaluated by ECAO for chronic
toxicity (listed in the Table 2-12, outline topic I-Cb) have different RQs in
the final rule because of changes and reevaluations brought about by
continuing peer review. These were originally treated by ECAO as not having
sufficient data to rank, but reevaluation of the data and/or additional data
has proven otherwise. These five hazardous substances are listed in the final
rule with their statutory RQs, pending completion of the chronic toxicity
evaluation.
Hazardous Substances Originally Assigned RQs Based on Chronic Toxicity, Now
Further Adjusted by Applying BHP
These two hazardous substances (Table 2-12, outline topic I-D) were previously
discussed in the section on BHP. See also Table 2-9.
2-135
-------
Hazardous Substances Where New Data on Aquatic Toxicity Results in Changed RQs
Sixteen hazardous substances (Table 2-12, outline topic I-Ea) fall into this
category. One of the commenters questioned the RQs based on aquatic toxicity
of numerous substances, and cited a major source of aquatic toxicity data
(12), which had not been previously considered. Based on the commenter's
concerns, all aquatic toxicity RQ assignments were reviewed, both to take into
account the new data and to insure conformity with the EPA guidelines for
evaluating aquatic toxicity data. (These guidelines are reviewed in Section
4, Acute Aquatic Toxicity, later in this document.) The result of this review
was that new RQ values were derived for the aforementioned 16 hazardous
substances. These new RQ values are the ones published in the final rule.
Following is a brief discussion of the data used to derive the new RQs for the
16 hazardous substances.
Aldicarb—
Data on the acute aquatic toxicity of Aldicarb were previously unavailable,
and therefore not reflected in the proposed 10-pound RQ. In reference (12),
the 96-hr LC^q for blueglll is given as 0.05 mg/1 which leads to an RQ of one
pound. This data point was the basis for the further RQ adjustment to one
pound.
4-Bromophenyl Phenyl Ether—
Non-standard data were used to derive the proposed 10-pound RQ for this
hazardous substance based on acute aquatic toxicity to invertebrates.
Standard data are found in reference (13) for bluegill. The 96-hr LC5q was
given as 5.9 mg/1 which supports adjustment of the RQ upwards from 10 pounds
to 100 pounds in the final rule. Corroborating data of 4.94 mg/1 96-hr LC,.q
for bluegill was also given in reference (14).
2-136
-------
Butyl Benzyl Phthalate—
Three standard data points were cited in references (12) and (13) that support
lowering the RQ of butyl benzyl phthalate from 5000 pounds to 100 pounds.
These data were 2.1 mg/1 and 5.3 mg/1 96-hr	for the fathead minnow, and
1.7 mg/1 96-hr	for the bluegill. Two data points from references (13)
and (14) support a 1000 pound RQ. These were 43.0 mg/1 and 43.3 mg/1 96-hr
LC50 for the bluegill. However, according to the prioritization convention
discussed in Section 4, the most conservative data are favored, so an RQ of
100 pounds was assigned in the final rule.
n-Butyl Phthalate—
Standard data were used to establish the proposed 100-pound RQ. These data
included values of 1.3 mg/1 and 1.2 mg/1 96-hr LC^q for the fathead minnow and
bluegill, respectively, from references (12) and (13). However, standard data
in reference (12) also gives the aquatic toxicity of n-butyl phthalate to
bluegill as 0.7 mg/1 96-hr	Using the most conservative data justifies a
further adjustment of the RQ for this hazardous substance to 10 pounds in the
final rule.
Dichlobenil—
The CWA Section 311 RQ for Dichlobenil was 1000 pounds based on standard data
for bluegill of 14.7 mg/1 96-hr	However, two standard data points
derived subsequent to the CWA Section 311 regulations supported a reduction in
the RQ to 100 pounds in the final rule. These data are 6.0 mg/1 and 8.3 mg/1
96-hr	for fathead minnow and bluegill, respectively, found in reference
(12).
2-137
-------
4,6-Dinitro-o-Cresol—
An RQ of 100 pounds was proposed for this hazardous substance on the basis of
standard and non-standard acute aquatic toxicity data. The standard data
point was 2.04 mg/1 96-hr LC,.q for the fathead minnow cited in OHMTADS (see
Section 6 for a description of the OHMTADS data base). However, additional
data in OHMTADS and reference (12) of 0.23 mg/1 and 0.36 mg/1 96-hr	^or
bluegill support lowering the RQ to 10-pounds in the final rule on the basis
of most conservative data.
Dinitrophenol and 2,4-Dinitrophenol—
The acute aquatic toxicity data used to propose an RQ of 100 pounds to the
dinitrophenol category and the 2,4-isomer was 1-10 mg/1 cited in RTECS (see
Section 6 for a description of the RTECS data base). The conditions under
which the range of data was generated is unknown. However, on the basis of
standard data cited in reference (14) of 0.62 mg/1 96-hr	for the
bluegill, the RQs for both the category and specific Isomer were lowered to
10-pounds in the final rule since it is the most conservative data.
Diethyl Phthalate—
The data used to propose a 100-pound RQ for diethyl phthalate in the May 25,
1983 NPRM was non-standard in that neither the species nor the test method are
standard. The cited data point was 1.2 mg/1 for the goldfish where only a
"lethal" observation was made Instead of a statistically derived LC^q value.
Additional data from reference (13) is 110 mg/1 96-hr LC^q for bluegill. This
would result in a 5000-pound RQ. However, the true concentrations of diethyl
phthalate in the test solution during this test is unknown since not all of
the chemical dissolved. Standard data of 98.2 mg/1 96-hr	for bluegill
from reference (14) leads to an RQ of 1000 pounds. The RQ of diethyl
phthalate was thus changed to 1000 pounds in the final rule.
2-138
-------
Kelthane—
The RQ for kelthane under the CWA was 5000 pounds based on data of 100 mg/1
LC50 cited in the supporting documentation to the CWA Section 311 regulations.
However this data is non-standard since rainbow trout was the test species and
the test duration was 48 hr. Standard data generated subsequent to the CWA
Section 311 regulations show an acute aquatic toxicity for kelthane of
0.52 mg/1 96-hr LC^q for bluegill as cited in reference (12). This data
supports adjustment of the RQ for kelthane to 10-pounds in the final rule.
Me thorny 1—
The RQ proposed for methomyl was 1000 pounds in the absence of any known acute
aquatic toxicity data. Acute aquatic toxicity data is provided in reference
(12). Four standard data points range from 1.05 mg/1 to 2.8 mg/1 96-hr
for fathead minnow and bluegill. These data support an RQ of 100 pounds. Two
data points from the same reference of 0.67 mg/1 and 0.71 mg/1 96-hr	for
bluegill would lead to an RQ of 10 pounds. However, because the preponderance
of data support a 100-pound RQ and the 0.71 mg/1 and 0.67 mg/1 data points are
near the 10/100-pound RQ cut-off point of 1 mg/1, the RQ of methomyl is
adjusted to 100 pounds in the final rule.
Pyrethrins—
The CWA Section 311 RQ for pyrethrins was 1000 pounds based on a standard data
point from reference (15) of 74 mg/1 96-hr	for bluegill. . However because
this data appears to have been published in a trade magazine of the pyrethrin
industry, rather than a peer-reviewed journal, its validity is open to
question. In addition, other more recent standard data from reference (12) of
0.058 mg/1 96-hr	for bluegill indicates a much greater acute aquatic
toxicity of pyrethrins. For these reasons, the RQ of pyrethrins is adjusted
to 1 pound in the final rule.
2-139
-------
2,4,5-T Acids and Salts—
The CWA Section 311 RQ for 2,4,5-T acid of 100 pounds was based on
non-standard test data both in terms of test duration and test parameter
(i.e., not 96-hr LC^q). Standard data in reference (12) of 10.4 mg/1 96-hr
LC^q supports adjustment of the RQ to 1000 pounds in the final rule. Although
no specific new data was found, the 2,4,5-T salts were assigned the same RQ as
the acid, since the active agent, the 2,4,5-T cation, is identical in each
case.
2,4,5-T Amines—
The CWA Section 311 RQ for 2,4,5-T amines of 100 pounds was based on
non-standard test data both in terms of test duration and test parameters
(i.e., not 96-hr LC^q). Two standard data points in reference (12) of
>100 mg/1 96-hr	for both bluegill and fathead minnow support adjustment
of the RQ to 5000 pounds in the final rule.
2,4,5-T Esters—
The CWA Section 311 RQ for 2,4,5-T esters of 100 pounds was based on
non-standard test data both in terms of test duration and test parameters
(i.e., not 96-hr LC^q). Standard data in reference (12) of 45 mg/1 96-hr LC5Q
for bluegill supports adjustment of the RQ to 1000 pounds in the final rule.
Hazardous Substances Where New Data on Mammalian Toxicity Results in a Changed
RQ
For the hazardous substance phosgene (listed in Table 2-12, outline topic
I-Eb) the commenter cited the 1000-pound RQ in contending that the RQ scales
used to evaluate mammalian toxicity lead to RQs that are higher than
appropriate. While the Agency has not changed its mammalian toxicity scales
(see earlier discussion on RQ scales), the commenter's concern prompted a
reexamination of the available toxicity data used to assign an RQ to phosgene,
2-140
-------
and these and additional data uncovered during the review indicate that the RQ
of phosgene belongs instead at the 10-pound level.
Both NIOSH's RTECS and the National Library of Medicine's Toxicology Data Bank
(TDB) give the following data for the inhalation toxicity of phosgene.
Rat,	= 50 ppm/30 minutes
Dog,	= 80 ppm/30 minutes
Guinea Pig,	= 7 ppm/20 minutes
Human, LC^q <= 3200 ppm
In assigning RQs based on inhalation toxicity, LCjq data from 4-hour exposures
are used in preference to	data generated using other exposure times, but
no such data is available in this case. A longer exposure time would lead to
lower value8. However, because two of the three animal values were in the
40-400 ppm range, (corresponding to a 1000-pound RQ level) and because the
human data would support an even higher RQ value, a RQ of 1000 pounds was
assigned originally. However, TDB, while not giving such information as part
of its toxicity values, states in reference to humans that 57 ppm can be fatal
if breathed for 30 minutes (16) and cites results from an additional animal
study (17) as follows:
Mouse, LC^q =5.1 ppm/30 minutes
These additional data indicate that the human toxicity value of 3200 ppm
originally cited, which is obviously out of line with all animal data, is not
supported by other citations, and should be discounted. With the additional
data on the mouse, there are now two values of mammalian inhalation toxicity
in the 4-40 ppm range corresponding to the 100-pound RQ level) as well as two
in the 40-400 ppm range (corresponding to the 1000-pound RQ level). However,
the lower of these two sets of values are for 20 and 30 minute exposures, not
for the 4-hour period that is usually considered the standard. Further, both
of the low values are near the 4 ppm level which separates the 10-pound and
2-141
-------
100-pound RQ levels. A 4-hour exposure would unquestionably result in a
toxicity value corresponding to a 10-pound RQ. In such cases, the Agency has
always elected to take a conservative position, and therefore the RQ assigned
to phosgene is ten pounds in the final rule.
Hazardous Substances Now Eligible for fi Chronic Toxicity Evaluation Because
Aquatic Toxicity Data No Longer Support 1-Pound RQs
These two hazardous substances are parathion and pentachlorophenol (Table
2-12, outline topic I-Ec), and were also reevaluated for aquatic toxicity RQ
rankings because of the commenter's concerns. In both cases, it has been
shown that the 1-pound RQ is not appropriate. However, these are substances
with known chronic toxic effects, but were not assessed for chronic effects
because they were already at the 1-pound RQ level, the lowest possible RQ
assignable. Once the 1-pound restriction is removed, these hazardous
substances become eligible for a chronic toxicity ranking, and are accordingly
listed in the final rule at their- statutory RQs pending completion of such
ranking.
Details of the reevaluation of the aquatic toxicity data for these hazardous
substances follows:
Parathion—
The RQ of parathion was 1000 pounds under the CWA Section 311 and was
unchanged in the May 25, 1983 NPRM on the basis of standard data contained in
documentation supporting the CWA Section 311 regulations. This data was a
single point of 0.095 mg/1 96-hr	for bluegill. However, this data point
was derived from a test that used an unusual soft-water test environment.
Other data in the CWA Section 311 documents are 0.71 mg/1 and 1.3 mg/1 (also
soft water) 96-hr	for bluegill and fathead minnow, respectively. These
data would support 10- and 100-pound RQs, respectively. Additional data in
reference (12) of 0.4 mg/1 and 2.35 mg/1 96-hr LC^q for bluegill and fathead
2-142
-------
minnow, respectively corroborates the latter two CWA Section 311 data points
cited above. Because of the unusual conditions that existed during the test
that generated the data used to set the original RQ of 1 pound for the CWA,
and the preponderance of data that suggest a less acute aquatic toxicity of
parathion, the RQ should be set at ten pounds based on aquatic toxicity.
However, pending an evaluation of chronic toxicity, parathion is assigned its
statutory RQ of one pound in the final rule.
Pentachlorophenol—
The 1-pound RQ for pentachlorophenol in the May 25, 1983 NPRM was based on two
standard data points found in reference (14). These were 0.06 mg/1 and
0.077 mg/1 96-hr LC^q for blueglll. Additional data from references (12) and
(14) support a 10-pound RQ. There are 24 data points cited in these two
references in the range of 0.18 mg/1 - 0.6 mg/1 96-hr LC^q for bluegill and
fathead minnow. Because of the overwhelming preponderance of test data that
support a higher than proposed RQ, the RQ should be adjusted to ten pounds
based on aquatic toxicity. However, pending an evaluation of chronic
toxicity, pentachlorophenol is assigned its statutory RQ of ten pounds in the
final rule.
Hazardous Substance Where New Data on BHP Results in £ Changed RQ
This hazardous substance is furfural (Table 2-12, outline topic I-Ed), and its
RQ was raised on the basis of a new BHP data source identified by a commenter.
(See earlier discussion on BHP.)
Hazardous Substance Now Eligible for ji Chronic Toxicity Evaluation Because BHP
Raises the RQ from 1_ Pound
This hazardous substance is hexachlorocyclopentadiene (Table 2-12, outline
topic I-Ee), and is another case where the RQ is raised based on new BHP data.
This change would raise the RQ from one pound to ten pounds. However, because
this hazardous substance is known to have chronic toxicity effects, it becomes
2-143
-------
eligible for a chronic toxicity evaluation. Accordingly, its RQ will remain
at the statutory 1-pound level pending the completion of such evaluation.
Error Corrections
Two errors are corrected. The nature of the corrections are shown in Table
2-12, outline topic I-Fa&b and are self-explanatory.
Changes in RQs for Unlisted Hazardous Wastes, Characteristic of EP Toxicity
The RQs of these wastes changed because the RQs of the constituent hazardous
substances on which they are based changed. The changes are shown in Table
2-12, outline topic II, and are self-explanatory.
Changes in RQs for Listed Specific and Non-Specific Hazardous Wastes Resulting
from Changes in Component Hazardous Substances
Nine hazardous wastes are given new RQs in the final rule as shown in Table
2-12, outline topic Ill-a. The changes are self-explanatory.
Errors and Inadvertent use of Superseded Data
Four errors in the RQs for listed hazardous wastes are corrected. The nature
of the corrections are shown in Table 2-12, outline topic Ill-b, and are
self-explanatory.
Substances and Wastes Designated as Hazardous Substances after Publication of
the NPRM
Coke oven emissions and hazardous waste F024 became CERCLA hazardous
substances by virtue of designation of coke oven emissions as a hazardous air
pollutant under the Clean Air Act and designation of F024 as a hazardous waste
under the Solid Waste Disposal Act. This occurred after publication of the
NPRM.

SECTION 3
ADMINISTRATIVE CONSIDERATIONS
ADMINISTRATIVE FACTORS
The legislative history of CERCLA makes it very clear that in setting RQs,
"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 Committee on Environment and Public Works
to accompany S.1480, states:
"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 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-pound
quantity statutorily assigned to all other Section 101(14) hazardous
substances. The term "administrative feasibility and practicality" may be
3-1
-------
interpreted in a very broad sense to include any practical factors deemed
relevant to administering the Act.
Although the RQ adjustment process described herein relies on scientific and
technical criteria based on some considerations of practicality and
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 following the procedure of
Section 2. Implementation of such modification of the RQs could be done, as
appropriate, on a case-by-case basis, taking into account those factors that
may be deemed relevant by the Administrator at the time the RQs are modified.
Despite the fact that there are currently no specific methods for applying some
of these factors, it is possible that as experience with the notification
requirement of CERCLA Section 103 is acquired, the Agency may develop
mechanisms 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
3.	Ease of clean-up
Any one or more of these factors might prove to have an overriding effect on
the RQ to be assigned to a particular hazardous substance for CERCLA. General
approaches to applying each of these factors are suggested below. However, for
various reasons none is deemed suitable for application to the adjustment of
RQs of hazardous substances at this time.
3-2
-------
Release History
Although the NRC, 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
hazardous substances released into navigable waters and transportation-related
releases provide a substantial history of release patterns, but not all the
CERCLA hazardous substances have been subject to reporting requirements
pursuant to the 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 CERCLA
hazardous substances, it may find that some hazardous substances are frequently
released in situations that require emergency responses. Such release history
might be used to adjust RQs. For example, if the EPA and other agencies have
in the past responded to 100-pound releases of particular hazardous substances,
100-pound or lower RQs would 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 methodology outlined in Section 2. A
possible way of using those factors is to raise the RQ assigned herein for
those hazardous substances with a much lower than average release frequency.
In deciding whether release frequency is much smaller or much larger than
average, those hazardous substances are to be compared which fall in the same
RQ tier based upon the same primary criterion. For example, RQs of hazardous
substances that have 100-pound RQs because of their aquatic toxicity and which
have much lower than average release frequency may be administratively raised.
3-3
-------
Release Potential
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, (A)
transportation mode, and (5) packaging and containerization. The Agency might
raise the RQs for hazardous substances that are less likely to be released.
1.	Price. Expensive hazardous substances may be handled in a fashion
that will minimize the likelihood that the hazardous substances would
be released or discarded as hazardous wastes (from which a later
release could occur). When a release of one of these hazardous
substances does occur, the releaser may have an economic incentive to
clean up the release to recover the hazardous substance. Hazardous
substances more expensive than average might therefore be given higher
RQs.
2.	Production volume or available quantity. Hazardous substances
produced in higher volume may be released more often than hazardous
substances produced in lower volume, and may therefore require lower
RQs than the low-volume hazardous substances.
3.	Distribution mode. Some hazardous substances are produced exclusively
as intermediates for use in the same plant location. 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 assigned
RQ may be relaxed because of the relatively small risk of release from
the limited distribution of the hazardous substance.
3-4
-------
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.
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 hazardous substances) may be
assigned RQs on the basis of the smallest package size. Hazardous
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 from a tank truck is more likely to involve a large
quantity of a hazardous substance than is a release from a case of
1-pound bottles. The RQs might therefore be set on the basis of
container size for some hazardous substances.
The above administrative factors might be used in the future to revise the
technically adjusted RQs presented in this report.
Ease of Clean-up
Another administrative factor considered for possible application to RQ
revision, but 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.

SECTION A
ACUTE AQUATIC TOXICITY
The purpose of this section is twofold. First, it provides supplementary
information on aquatic toxicity testing for those readers who desire a broader
understanding of this subject. To this end the Overview of Aquatic Toxicity
Testing section below provides a brief introduction to aquatic toxicity
testing. The next section, Nomenclature, explains the various terms and
acronyms associated with aquatic toxicity testing. The third section,
Methodology, describes the methods that are used to determine the acute
aquatic toxicity of a hazardous substance.
The second purpose of this part of the report is to discuss how RQs are
assigned on the basis of aquatic toxicity, and to explain the criteria used in
deciding how to select the most appropriate data to be used when multiple (and
sometimes inconsistent) data are available. This latter subject is discussed
in the section titled, RQ Adjustments Based on Aquatic Toxicity.
OVERVIEW OF AQUATIC TOXICITY TESTING
During the past 25 years, aquatic bioassay has become 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 environmental factors (e.g., pH, dissolved oxygen, light), alone or
in combination, on aquatic organisms (18).
An aquatic bioassay which tests the effects of toxicants on organisms provides
Important information that is useful for protecting the aquatic environment,
such information being unavailable from chemical examination alone. The
results from aquatic bioassay testing of a toxic agent are used to determine
4-1
-------
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 sensitivites of a number of species
to a single toxicant, the maximum allowable toxicant concentration which
causes no long-term negative effects, and the maximum allowable toxicant
concentration for very short exposures (e.g., periodic discharges).
In recent'years, the procedures for conducting aquatic bloassay testing have
become standardized. Much of what follows is based on the standard methods
and procedures found in the scientific literature (18).
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: death, paralysis, deformity, lowered
resistance to disease, developmental abnormality, lowered reproductive
capacity, impairment of other bodily functions, or loss of other competitive
abilities.
When death is the criterion of toxicity, the bioassay is conducted to
determine the lethal concentrations (LC) of the toxicant. When a criterion
other than death is of interest, the bioassay can be used to determine the
effect of toxicant concentration on paralysis, for example. In such cases,
the effective concentration (EC) is specified. 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.
4-2
-------
A numerical suffix and prefix always accompany the LC or EC designation. For
LC, the suffix is the percentage of organisms experiencing death (or some
other effect for EC) at the designated concentration. The prefix is the
duration of the bloassay. For example, 96-hour	= 100 ppm means that 50%
of the test organisms exposed to the toxicant at 100 ppm would be expected to
die within 96-hours (the 96-hour bioassay is usually used to measure acute
toxicity).
Recent standard aquatic bioassay procedures (18) specify the use of LC and EC
when reporting results. However, much of the literature on aquatic toxicity
contains median tolerance limits, or TL^. When lethality is the criterion of
toxicity, the TL^ = LC^q. When a nonlethal criterion is used, then
TL = ECcrv. However, it should be understood that the tolerance limit
m jU
specifies the percentage of organisms able to tolerate exposure to the
toxicant over the duration of the test. Thus, for example,	= LC9q ^or
death) and	= EC^q (for nonlethal effects).
There are other Important data that can be gleaned from aquatic bioassay
testing. The first of these is incipient lethal level, also called the
incipient LC^q. This is the toxicant concentration at which 50% of the test
organisms can be expected to die on long exposure (19). Incipient EC,.q 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 LC^q and an incipient LC^q can be two very different numbers with
vastly different meanings.
The most important data values, from an environmental viewpoint, that are
obtained 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
4-3
-------
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.
METHODOLOGY
Aquatic bloassay testing exposes a test population of a particular species to
various concentrations of a toxicant for a predetermined period of time or
until a specific effect is observed. The effect of each concentration on the
test population is determined, and through statistical means the LC, EC, SC,
or MATC values are derived depending on the type of bloassay performed.
Aquatic bloassay procedures are often categorized by duration, which includes
short-term, intermediate-term, and long-term tests. Short-term aquatic
bloassay tests are of two types: range-finding and definitive. Range-finding
short-term bloassay is used to screen a toxicant to determine the proper
concentrations to use for longer term testing. Definitive short-term bloassay
can be used 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 bloassay is used to determine incipient ^C^q and
incipient EC,.q 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 bloassay.
Long-term aquatic bloassay 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 such as: growth, reproduction,
maturation, bioaccumulation, and behavior.
Short and intermediate bloassay can be performed using static, renewed, or
flowthrough conditions. Long-term bloassay is usually performed as a
flowthrough test. A static bloassay test uses the same aqueous test solution
4-4
-------
throughout. Static testing is not indicated 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 testing is the most desirable type since a constant
toxicant concentration is assured and field conditions can be more closely
simulated. However, the experimental apparatus is Immensely more complicated
and costly than that used for static bioassay testing. The apparatus includes
water reservoirs, pumps, drains, 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, 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 fathead minnow (Pimephales
promelas Rafinesque) is used extensively in the United States. Similarly, the
bluegill (Lepomis macrochirus Rafinesque) is also widely used in the United
States. 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 common goldfish (Carassius auratus [L.]) may become
a standard fish, primarily because of its availability (20).

RQ ADJUSTMENTS BASED ON AQUATIC TOXICITY
Aquatic toxicity is one of the criteria used for adjusting the RQs of
hazardous substances designated pursuant to CERCLA Section 101(14). A
complete explanation of the preferred adjustment methodology appears in
Section 2 of this report. This section discusses how aquatic toxicity data
are used to adjust RQs and the type- of data that, are considered acceptable for
determining the RQ adjustment.
The method for adjusting the RQ of a CERCLA hazardous substance based on acute
aquatic toxicity is identical to that used previously by the EPA for assigning
RQs to substances regulated by the CWA. Five ranges of acute aquatic toxicity
are used under the CWA and for adjusting CERCLA RQs. The technical basis for
this five-tier system is described in detail in the Preamble to Final
Rulemaking A3 FR 10492, March 13, 1978, and in the associated technical
background document, EPA-440/9-75-(a-d), January 1975. These five tiers are:
Category Aquatic Toxicity	RQ (Pounds)
X LC50 <0.1 mg/1	1
A	0.1 mg/1 
-------
The 96-hr LC^q aquatic toxicity test is the test that is used most frequently
to assess acute aquatic toxicity. It may therefore be considered the standard
measure of acute aquatic toxicity. Because of the large data base generated
with this standard test, it was the test method of choice for establishing the
CWA RQs (21). Data generated from it are preferred for adjusting the RQs of
CERCLA hazardous substances based on the aquatic toxicity criterion.
Standard species and a standard life stage of individuals used in acute
aquatic toxicity testing have also been established for the purpose of CERCLA
RQ adjustment, again based on precedents established during previous EFA work
(22, 23). The standard species are the fathead minnow and the bluegill,
primarily because of the large data base generated from acute aquatic toxicity
tests and because they are relatively sensitive to most toxicants (23). Other
species of fish have been used for testing acute aquatic toxicity, but not to
the same degree as these standard species. In addition, a number of different
Invertebrate species have been used for assessing acute aquatic toxicity.
However, particularly with the pesticides, one of the problems with data
generated using such test species is that oftentimes the chemical substance
being tested has been formulated to be most lethal to the invertebrate species
used in the test, or to other closely related species. Therefore, the data
suggest a greater toxicity than would otherwise be indicated if non-target
species were used. Such species-specific tests are beneficial when the
purpose of the test is to determine the impacts of a substance on that
particular species or to determine impacts to an ecosystem. However, RQ
adjustment must be based on comparable, reliable, consistent, and standard
acute aquatic toxicity data since the interest is to identify relative
differences in toxicity rather than the effects of a substance on an
ecosystem. Data from 96-hour LC^q tests using the fathead minnow or the
bluegill are best for this purpose.
4-7
-------
In addition to the importance of considering data from tests using the
standard species and standard tests (96—hr LC^q) for assessing acute aquatic
toxicity for the purpose of RQ adjustment, the life stage of the individuals
used during the test is also important. Evaluating tests that use the same
life stage will assure that consistent, standard data are used to identify the
relative differences in acute aquatic toxicities between hazardous substances.
The standard life stage (as defined by the- weight of the individual test
organisms) for the purpose of RQ adjustment of the CERCLA hazardous substances
again has precedent in previous EPA work (22, 23). These studies considered
individuals weighing between 0.5 grams and 5.0 grams to be acceptable. This
same weight range is considered to be the standard for data used to adjust the
RQs of CERCLA hazardous substances.
The previous discussion has defined, and provided justification for using
standardized acute aquatic toxicity data as the basis for adjusting the RQs of
CERCLA hazardous substances for the aquatic toxicity criterion of the
preferred RQ adjustment methodology. To reiterate, the standard data is a
96-hr LC^q value based on a test using either the fathead minnow or the
blueglll as the test species in a weight range of 0.5 to 5.0 grams. However,
it is recognized that in the absence of the above defined standard data, other
non-standard data are beneficial for assessing the acute aquatic toxicity of a
CERCLA hazardous substance for the purpose of RQ adjustment. Data that most
closely approach standard data are most desirable. Therefore, the following
prioritization of non-standard test data was established and used for
adjusting the RQs of CERCLA hazardous substances when standard data were
unavailable:
1.	96-hr LC^q for any fish species with individuals weighing between 0.5
and 5.0 grams.
2.	48-hr LCcq or 24-hr LC^q for any fish species with individuals
between 0.5 and 5.0 grams.
3.	LC^q data for any fish species regardless of life stage.
4-8
-------
In the case where data were not in total agreement but were comparable in
terms of test methodology, the most conservative data (i.e., greatest
toxicity) were used to adjust the RQ. Preponderance of data was also
considered in the RQ adjustment methodology based on acute aquatic toxicity.

SECTION 5
ACUTE MAMMALIAN TOXICITY
This section of the report provides supplementary information to those who
desire a broader understanding of the methods used to determine the toxicity
of chemicals to mammals. 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 measure of harm. RQs only
alert OSCs that they should evaluate a release situation to determine if a
response is warranted.
OVERVIEW OF MAMMALIAN TOXICITY TESTING
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 covered by hair to a certain extent)
represent a single class of vertebrate animals. Mammals share basic
characteristics of appearance/ anatomy/ and most important/ physiology.
It has been demonstrated from 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
5-1
-------
toxicity testing on humans, it is the best method currently available for
assessing potential chemical hazards to humans. However, animal bioassays are
by no means an absolute method for predicting effects in humans. With some
chemicals 10- to 12-fold differences in susceptibility to toxicants between
mice and humans have been observed (24).
The following sections discuss the nomenclature used in toxicity testing using
mammals, the methods employed for these tests, and the RQ adjustment
methodology as it relates to acute mammalian toxicity.
NOMENCLATURE
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, including vapor inhalation
(at a given concentration), application of 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, the data are expressed as
lethal concentration (LC) if the toxicant is an inhalant, or lethal dose (LD)
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, LD, TC, and TD designations are followed by a numerical suffix. For
example (25):
LC^-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
mammalian population.
5-2
-------
LD^Q-Lethal Dose Fifty - a calculated dose of a substance which is
expected to cause the death of 50% of an entire defined experimental
mammalian population by any route other than inhalation.
TC^Q-Toxic Concentration 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 mammal population.
TD^-Toxic Dose Fifty - a calculated dose of a substance which 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.,	are reported
in the literature.
Review articles or compendiums of toxicity data (25) often report	^lo'
TC^q/ or TD^q values. These are the lowest reported values from the
literature (either concentrations or doses) which cause either death or other
toxic effects.
For LD or TD, the dosage units are usually given in terms of the quantity of
toxicant per unit body weight (e.g./ mg/kg). When the substance is applied
dermally/ results may be expressed either as the quantity of toxicant per unit
area of skin (e.g./ mg/an ) or as the quantity of toxicant per unit of body
weight (mg/kg). 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/ whether the exposure was continuous or
discontinuous/ and the frequency of the exposure. For example/ 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
5-3
-------
accurately compared.
METHODOLOGY
The following discussion of the methodology employed in mammalian toxicity
testing is divided into sections on general considerations, routes of toxicant
administration, toxic effects which are commonly 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 on physiological functions. Testing must be
performed using strict protocols, including the use of accurate dosing
equipment, maintaining cleanliness, and assuring that the test animals are
exposed to minimal external stress. For example, rats which are housed singly
develop high blood pressure (26) which in time, 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, systemic effects) and
5-4
-------
lethal toxic effects, either acute or chronic.
Administration of toxicants by inhalation is achieved using several methods.
For example, the animals can be placed in a test chamber whose atmosphere is
dosed with the toxicant, the toxicant can be adminstered by mask, or by
cannulation (intubation of the respiratory tract). Lethal, sub-lethal, acute
and chronic effects can be determined using these methods of toxicant
administration.
Oral administration of toxicants is achieved by dosing either the food or
water via capsule or tablet, or by gavage (intubation into the stomach).
Lethal, sub-lethal, acute, and chronic effects can be determined using these
methods of toxicant administration.
The method chosen for adminstration of the toxicant will, in part, depend on
the mode of entry of the toxicant that is most likely to be encountered in the
environment. For example, PCBs pose risk when absorbed through the skin and
when ingested. Both modes of exposure are possible with PCBs since they may
be found in transformer oils and drinking water. Therefore, skin application
and oral ingestion methods of administration are used most frequently in
toxicity testing of PCBs.
Toxic Effects
Sub-lethal or toxic effects by 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
change. Exposure can result in aberrations in the offspring of those exposed
(teratogenicity). Changes in behavior may be brought about after exposure to
toxicants.
5-5
-------
Test Species
A wide variety of mammals are used in toxicity testing. Two of the most
common 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
long-term testing can require hundreds of animals.
Other mammalian species used in toxicity testing include:
Cat	Guinea Pig
Cattle	Hamster
Horse	Monkey
Dog	Pig
Goat	Rabbit
Sheep	Squirrel
RQ ADJUSTMENTS BASED ON ACUTE MAMMALIAN TOXICITY
RQs are assigned in part based on acute toxicity to mammals. This is
necessitated by the fact that few reliable data exist on the toxicity of
chemicals to humans. On the other hand, there are toxic effects which are not
easily observed in animals, but clearly manifested in humans. 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 small
amounts of the toxicant over long periods of time, although such conditions
are occasionally simulated. Such long-term studies are exceedingly costly to
perform.
Despite the limitations in the use of nonhuman mammalian toxicity data for
predicting subtle effects in humans, the use of the gross effect (namely,
death) and the resultant comparison of chemical toxic effects on the basis of
lethal doses (LD5qs) 'ias much to recommend it. Such values will generally
5-6
-------
fall In the same range for a wide variety of mammalian species, and may thus
be extrapolated to humans with a reasonable degree of accuracy. Furthermore,
LD50 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.
Accordingly, the preferred RQ adjustment methodology uses acute mammalian
toxicity as one of the primary criteria. Data from the rat, which is believed
to be most readily related to the effect in humans, are used whenever
available. Data from other mammalian species are also used, when in the
absence of, or in combination with data from the rat. If the data from a
number of species or a number of tests with the same species are not
consistent, then the most conservative values are used, unless the
preponderance of data Indicates otherwise.
The method for adjusting the RQ of a CERCLA hazardous substance based on acute
mammalian toxicity considers toxicity via oral, dermal, and inhalation routes.
Five ranges of acute mammalian toxicity for each of the three routes provide
the basis for an RQ. These ranges are:
Category
Maimalian Toxicity (Oral)

SECTION 6
TECHNICAL INFORMATION RESOURCES
Because of the large number of hazardous substances under review In this
effort, and the diverse information that had to be collected on each hazardous
substance, existing data bases were used as the major technical Information
resources. For speed and ease of assembling records for files and dockets,
emphasis was placed on those data bases which could be accessed, searched, and
printed by computerized techniques. These data bases are reviewed in the
paragraphs that follow.
THE NIH/EPA CHEMICAL INFORMATION SYSTEM (CIS)
The CIS is a collection of computerized data storage and retrieval modules 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 21 modules (components) of the CIS are listed below, and the structure of
the CIS is depicted in Figure 6-1.

The modules of the CIS communicate among themselves by stored lists of CAS
Registry Numbers (CASRNs). In the case of some modules/ for example the CTCP/
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 CASRN). A given list of citations
is automatically converted to a list of the pure CASRNs of all the compounds
referenced in that list when it was generated. In some modules/ where more
than one "entry" for a CASRN is possible, a subidentifier is appended to the
CASRN. 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 CASRNs being generated and stored. For
instance, within the 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
6-3
-------
the CASRNs for those compounds satisfying the criteria specified.
For essentially all the compounds in the CIS the following information is
available:
o CASRN
o Structure
o The chemical name and molecular formula in accordance with the
introductory sections of the TSCA, Chemical Substances Inventory,
Volume 1/ May 1979
o CAS Collective Index Name(s)
o A list of sources of further information
o Other names and synonyms by which the substances are commonly
known in commerce and manufacturing
In addition, as described in the following sections, additional information,
e.g., mass spectrum, toxicity data, regulations, 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 RQ 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 (27),
or the on-line information.
Oil and Hazardous Materials Technical Assistance Data System (OHMTADS)
OHMTADS is an automated information retrieval file designed to facilitate
rapid retrieval of information on oil and hazardous substances. 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. Currently, there is information in the system for about 1200
6-4
-------
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 general source of diverse information on hazardous substances.
OHMTADS data have been gathered from the open literature.
OHMTADS 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 material name is contained in the MAT field, the
recommended drinking water limits in the DRK field. 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)
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.
OHMTADS allows a search for materials with certain values of specified
properties (for example, the specific gravity or vapor pressure) or ranges of
those properties. OHMTADS also provides recommended methods for disposing of
spilled hazardous substances (DIS), and for notifying proper authorities
(DSN).
Structure and Nomenclature Search System (SANSS)
The SANSS module data base is designed to contain an entry for each chemical
compound included in the data bases associated with the other individual CIS
components. Each such entry includes, as available: CASRN; systematic name
(CAS 8th Collective Index and/or 9th Collective Index); synonyms and trade
names; molecular formula; connection table; and references to other sources
of information. Currently there are approximately 200,000 chemical substances
in the data base. One can query this system for compounds having particular
characteristics. For example, one can search for all compounds having a
specific structural fragment contained within them. To accomplish this, the
user describes the two-dimensional structural fragment by means of simple
6-5
-------
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* partial, or ranged); molecular weight/ and atom count.
NIOSH Registry of Toxic Effects of Chemical Substances (RTECS)
The search and retrieval system for the NIOSH RTECS is based on the NIOSH
hardcopy 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 over 63,000 compounds.
The direct search allows the user to display, for a given list of compounds,
the CASRN, 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 from other modules of the CIS.
Toxic Substances Control Act Plant &_ Production Data (TSCAPP)
The TSCAPP data base originated as the production and plant site information
associated with the TSCA Chemical Substance Inventory: Initial Inventory.
This information was originally contained in two tape files (28).
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 commands, but can be combined in various
ways for display. For example, searches performed by CASRN will allow
assessment of the total annual production of a given compound, and the
6-6
-------
manufacturing sites can be identified.
Other CIS Modules
Two modules have been of only limited usefulness to the RQ program. They are:
FRSS — Federal Register Search System, and
CTCP — Clinical Toxicology of Commercial Products
As part of the designation studies, the FRSS has been used as a source for
identifying chemicals of concern to other federal agencies. CTCP has provided
a very limited amount of toxicity data in addition to the data available in
RTECS.
Several recently-added nodules which may prove useful in the future include:
SPHERE — Scientific Parameters for Health and the
Environment, Retrieval and Estimation,
CCRIS — Chemical Carcinogen Research Information System,
CESARS — Chemical Evaluation Search and Retrieval System,
CLEAR — Clearinghouse Search System,
SPHERE, CESARS, and CCRIS contain information on toxicity and environmental
effects, but were added to CIS after the major effort on collecting data for
the RQ adjustments had been completed. CLEAR is essentially an index to EPA
models, data bases and reports. Any or all of these may be useful to the RQ
program if new substances requiring RQ adjustments are listed via RCRA or
other regulations, or in future studies of designation strategies.

DIALOG DATA BASE
The Dialog Information Retrieval System is operated by DIALOG Information
Service/ Inc. Dialog is an on-line, interactive system composed of
approximately 150 separate data bases which the user can access directly. By
using a carefully designed key-word search strategy/ the user is able to
extract desired information from a DIALOG data base. The user can command
that the information be printed off-line and the hard-copy output be sent to
his address.
Four principal DIALOG data bases were used to obtain data on the CERCLA
hazardous substances. These were Aqualine/ Enviroline/ Environmental
Bibliography/ and Pollution Abstracts. Descriptions of these data bases
appear below.
Aqualine
Aqualine provides access to information on every aspect of water, wastewater/
and the aquatic environment. Corresponding to Water Research Center (WRC)
Information, Aqualine coverage includes water resources development and
management/ drinking water quality, water treatment, sewage systems, sludge
disposal, ground water pollution, river management, tidal waters, quality
monitoring, and environmental protection. Worldwide sources cited are 600
periodicals/ research reports, legislation, conference proceedings and
preprints, books, monographs, pamphlets, dissertations, translations,
standards and specifications, and miscellaneous publications from
water-related institutions worldwide. This data base is managed by the WRC,
Medmenham, Buckinghamshire, England. It is updated monthly.
6-8
-------
Enviroline
Enviroline, produced by the Environment Information Center (EIC), provides
interdisciplinary coverage of the scientific, technical/ and socioeconomic
aspects of the major English and non-English language environmental and
resources literature. The printed equivalent is Environment Abstracts.
Subjects related to the project include:
Air pollution
Chemical and biological contamination
Food and drugs
General environmental topics
Land use and misuse
Oceans and estuaries
Solid waste
Water pollution
Wildlife
Enviroline draws material from approximately 5000 primary and secondary
sources of information including more than 3500 scientific, technical, trade,
professional, and general periodicals: papers and proceedings from
environment and resources related conferences; documents and research reports
from private and governmental agencies; Congressional hearing transcripts;
environmental project reports; and newspaper articles. It is updated
monthly.
Environmental Bibliography
The Environmental Bibliography covers the fields of general human ecology,
atmospheric studies, energy, land resources, water resources, and nutrition
and health. More that 300 periodicals are indexed in Environmental
Bibliography. Environmental Bibliography is updated on a monthly basis. It
is managed by the Environmental Studies Institute, Santa Barbara, California.
6-9
-------
Pollution Abstracts
Pollution Abstracts is a leading resource for references to environmentally
related technical literature on pollution/ its sources,^and its control.
Produced by Data Courier, Inc./ the data base corresponds to the printed
Pollution Abstract. Of the subjects covered by the Pollutant Abstracts data
base/ the following are of interest to this study:
Air pollution
Freshwater pollution
Land pollution
Marine pollution
Sewage and wastewater pollution
Toxicology and health
Waste management
References in Pollution Abstracts are drawn from approximately 2500 primary
sources from around the world/ including books/ conference papers and
proceedings/ periodicals/ research papers/ and technical reports. References
date from 1970 to present, and are updated bimonthly.
MEDLARS DATA BASE
The MEDLARS data base is an on-line search and retrieval system operated by
the National Library of Medicine (NLM). MEDLARS essentially provides
computerized access to the Index Medicus. MEDLARS is composed of a number of
different data bases. Three of these data bases deal specifically with the
toxic effects of chemicals and these were accessed to obtain this type of
information on the CERCLA hazardous substances. These were Toxline
(Toxicology Information Online)/ Toxback, and TDB (Toxicology Data Bank)/ each
of which is described separately below.
6-10
-------
TOXLINE and TOXBACK
TOXLINE is an interactive bibliographic retrieval system for toxicology
consisting of 11 discrete subfiles in the master data base. The component
subfiles include Chemical-Biological Activities (CBAC)/ Section 1-5 frcm 1965*
Section 62-64 frcm 1975, and Section 8 (Radiation Biochemistry), Section 59
(Air Pollution and Industrial Hygiene), and Section 60 (Sewage and Wastes),
from 1975; Toxicity Bibliography (TOXBIB) from 1968; Abstracts on Health
Effects of Environmental Pollutants (HEEP) from 1972; International
Pharmaceutical Abstracts (IPA) from 1970; Pesticides Abstracts (PESTAB),
Environmental Mutagen Information Center file (EMIC) from 1960; Environmental
Teratology Information Center file (ETIC) 1971-75; a teratology file (TERA)
1960-74; a special collection of materials about pesticides gathered by
Dr. W.J. Hayes, Jr., (HAYES) from 1940-1966; and Science Information Exchange
(SSIE) data base, beginning in 1979. All of the subfiles are arranged so that
they may be searched simultaneously in response to a single query. Each
record in the TOXLINE data base contains a full bibliographic citation, most
with abstracts and/or indexing terms, and CASRNs.
The on-line file contains material published in secondary sources from 1974 to
the present and is updated regularly. In TOXLINE are all of the EMIC and ETIC
items, regardless of time coverage. Older information, approximately 380,000
records, is in TOXBACK (the TOXLINE backfile available through OFFSEARCH
only). The HAYES and TERA subfiles are only available in TOXBACK. Both
TOXLINE and TOXBACK are accessible at NLM only.
TDB
The TDB is an on-line, interactive file that contains facts and data frcm some
61 active standard reference textbooks, handbooks, monographs, for
approximately 2500 substances; 1100 of these have been completed, 1500 are in
process. The TDB has information organized around a chemical substance, like
RTECS. The TDB contains approximately 60 different categories of data, such
6-11
-------
as chemical, physical, biological, pharmacological, toxicological,
environmental facts. Specific data elements include CASRN, synonyms,
molecular formula and weight, human and animal toxicity, antidote and
treatment.
The data have been reviewed by a peer review group of scientists from NIH's
Study Section in Toxicology, which is comprised of pharmacologists,
toxicologists, and chemists.
The TDB is searchable primarily using free text terms like T0XL1NE,
prequalifying the terms with the desired search groupings. Only three fields
have been indexed with Medical Subject Headings, MESH vocabulary. These three
fields are human toxicity excerpts, animal toxicity excerpts, and laboratory
methods excerpts.
The file became available to the public on October 30, 1978, to U.S. on-line
centers. Additions to the file are made quarterly.
RTECS
RTECS is available in MEDLARS as well as in CIS, and may be searched using
different protocols from those available in CIS. In particular, free-text
searching can be conducted. Occasional use has been made of these features to
search for data on hazardous substances not found using CIS search protocols.
OTHER DATA BASES
Data Submitted under TSCA Section 8(e)
Under TSCA Section 8(e), if the regulated community (processors,
manufacturers, or distributors of chemical substances) "obtains information
which reasonably supports the conclusion that such substance or mixture
presents a substantial risk of injury to health or the environment," the
6-12
-------
information must be provided to the Agency. This section of TSCA is
considered self-implementing (Agency policy statement/ 43 FR 1110/ March 16/
1978).
The Public Information Reference Unit (PIRU) of the Agency's Office of
Pesticides and Toxic Substances (OPTS) maintains a data base consisting of
file copies of information submitted by the regulated community in response to
TSCA Section 8(e)/ Agency correspondence with the regulated community relative
to such submissions/ and Agency status reports which are periodically updated.
The files are indexed on an individual chemical basis. Preliminary review of
the files identifies approximately 95 of these chemicals as CERCLA hazardous
substances.
However/ the data in these files have not been peer reviewed by the EPA/ and
these data therefore could not be immediately used in setting RQ levels. When
these data have been peer reviewed and validated by the EPA Office of Research
and Development (ORD) or other similar technical review groups/ they can be
used for setting RQ levels along with other data.
Nonetheless/ these files represent a source of data, unpublished and
unavailable elsewhere/ from relatively recent studies conducted with hazardous
substances. While these data have not been used in the process of
establishing RQs thus far/ they would become extremely important if properly
peer reviewed should contention over any particular RQ assignment develop
between the Agency and the regulated community.

SECTION 7
DATA TABLES FOR HAZARDOUS SUBSTANCES OTHER THAN
THOSE CLASSIFIED AS WASTES UNDER RCRA
Detailed data tables showing the basis for the final RQs for the hazardous
substances following the preferred RQ adjustment methodology and BHP
adjustments as described in Section 2 are presented in Table 7 -1. This list
includes all those hazardous substances designated under the CWA Sections
311(b)(4) and 307(a) and the hazardous air pollutants designated under the CAA
Section 112. Hazardous substances designated under RCRA Section 3001 appear
later in Section 8. The tables include the data on aquatic toxicity,
mammalian toxicity (oral, dermal, and inhalation), chronic toxicity,
ignitability, and reactivity upon which the choice of the final RQ is based.
As discussed elsewhere in this report, many hazardous substances remain to be
assessed for chronic toxicity or potential carcinogenicity by the ECAO or CAG,
respectively, and these hazardous substances are appropriately flagged "CHRON
TBA" or "CARC TBA" in the column titled "CARC/CHRON-Note 4." No RQs have yet
been assigned based on potential carcinogenicity and the symbol (#) in the
Final RQ column identifies those substances still to be assessed for potential
carcinogenicity. In those cases where the chronic toxicity assessments are
incomplete the symbol (##) appears in the Final RQ column. The symbol (###)
indicates that both potential carcinogenicity and chronic toxicity are being
assessed. The final RQ listed in Table 2-1 for hazardous substances still
under assessment are the CWA Section 311 or the CERCLA 1-pound statutory RQs
and are identified with an (#), or (##) to show that they may undergo further
adjustment when assessment is complete.
Data entered in the Aquatic Toxicity, Mammalian Toxicity, CARC/CHRON, and I/R
column are followed by a letter (X, A, B, C, or D) indicating the RQ level
corresponding to that particular data point. The numerical value
corresponding to the lowest level so identified is given in the Final RQ
7-1
-------
column.
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 7-1, the most
common abbreviations are as follows:
(X), (A), (B), (C), (D) - RQ Categories 1, 10, 100, 1000, and 5000
pounds, respectively
CARC TBA - To be assessed for potential carcinogenicity
CHR0N TBA - To be assessed for chronic toxicity
CHR0N* - Hazardous substance is a known chronic toxicant, but since
its RQ has already been adjusted as low as possible
(one pound) on some other basis, it will not be assessed
for chronic toxicity.
F - Flash point (°F)
B - Boiling Point (°F)
311 - The RQ was established on the basis of aquatic toxicity
under the regulations from the CWA Section 311
AQTX - Aquatic toxicity (other than a CWA Section 311 assignment)
CTX - Chronic toxicity
BHP - Biodegradation, hydrolysis, or photolysis
I/R - Ignitability and reactivity
CS - The RQ was assigned on the basis of chemical similarity to
another hazardous substance, in the absence of data for the
primary criteria.
Max - Maximum possible RQ assignment

NOTES FOR COMPREHENSIVE HAZARDOUS SUBSTANCES LIST
PART I - CHEMICALS
NOTE 1: The hazardous substances which appear on this comprehensive hazardous
substances list (Table 7-1) are those chemicals which comprise Part I of
the CERCLA Section 101.14 list. At the present time these include the
following: 297 chemicals designated under CWA Section 311(b)(4) (40 CFR
117); 126 specfic chemicals (priority pollutants) designated under the
CWA Section 307(a); and finally eight chemicals (six of which are
duplicates already listed under Section 307(a)) designated under the CAA
Section 112 (proposed 40 CFR 61). No entries have been listed under TSCA.
NOTE 2: Aquatic Toxicity, unless specifically noted otherwise, is given as the
TL 96 (The 96-Hour Median Threshold Limit) for aquatic species. Tkm96 is
that concentration of the material dissolved in water, in parts per
million (ppm) or milligrams/liter (mg/1) (which are equivalent) that will
kill 50% of the test organism population in 96 hours. Each TLm96 entry is
followed by a letter indicating the RQ category to which it corresponds,
on the following scale:
RQ (Pounds-)
X (1)
A (10)
B (100)
C (1000)
D (5000)
Note that TL and LCcq (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 RQs assigned under CWA Section 311, as given in 40 CFR 117.3. The
detailed listing of aquatic toxicities that form the basis for these
assignments is found in report No. EPA 440/9-75/009, "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," RTECS,
accessed as a machine-searchable data base via the EPA/NIH CIS. RTECS
is available in hardcopy, the latest being DHHS (NIOSH) Publication
No. 83-107, "1981-1982 Registry of the Toxic Effects of Chemical
Substances," Volumes 1, 2, and 3, U.S. Department of Health and Human
Services, Public Health Service, Center for Disease Control, National

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 LD5D (Dose Lethal to 50% of the test animal population)
in milligrams per kilogram of body weight (mg/kg). Test species are
coded using the RTECS convention, as follows:
Hmn = human
Rat = rat
Mus = mouse
Gpg = guinea pig
7-39
-------
Dog = dog
Rbt = rabbit
Thus the entry "Rat-orl:60" Indicates an oral	of 60 mg/kg for
rats.
B.	Dermal Toxicity; These entries are indicated by the abbreviation
"skn" immediately following the species code, and are again given as
the acute LD,-q (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	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	of 60 ppm for 4 hours for
rats.
D.	Low Lethal Dose or Low Lethal Concentration; These are shown by the
terms "LD '* or "LC^o." LD^ and LC. are the lowest doses or
concentrations known to°have haS lethal effect on the test species.
Thus the entry Rat-ihl LC^q:60/4H indicates an inhalation LC^q of 60
ppm for 4 hours for rats.
Note; Human LC 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 RTECS
(See Note 2B, above.)
E.	Toxic Dose (or Concentration); These are shown by the designation TD
(for dose) or TC (for concentration). This means that the data
represents a dose at which signs of toxicity other than immediate
death were noted.
Each toxicity entry is followed by a letter indicating the reportable
quantity to which it corresponds, on the following scales:
7-40
-------
Oral LD^q Dermal LD^q Inhalation LC^q
or lo	or lo	or lo	RQ (Pounds)

100-500	40-200	400-2000	D	(5000)
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 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 "CHR0N TBA" is used to identify those hazardous
substances 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:
1.	"The Registry of the Toxic Effects of Chemical Substances," RTECS,
accessed as a machine-searchable data base via the CIS. RTECS now
contains information on over 63,000 chemical substances.

C.	The entry "CHR0N*" Indicates that the hazardous substance is known to
have a chronic effect, but since its RQ has already been set at the
1-pound 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 potential carcinogenicity by the
EPA CAG, and therefore the statutory RQ of the material applies until
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:

NOTE 5: I/R: Ignitability 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 ignltable.
B.	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 RQ category to which it corresponds, based on the
following scales:
7-43

Data for ignitability and reactivity ratings were taken from "Fire
Protection Guide on Hazardous Materials," 7th Edition, National Fire
Protection Association, Boston, Ma, 1978.
NOTE 6: Entries under this column show the RQ that was assigned under CWA Section
311 (40 CFR 117.3).
NOTE 7: Entries in this column are the lowest RQs derived from the individual
rankings shown under the Aquatic Toxicity, Mammalian Toxicity, Chronic
Toxicity, and/or I/R columns, or (b) the entries are flagged as follows to
indicate that the hazardous substance is under assessment for potential
carcinogenicity and/or chronic toxicity, and the statutory RQ will be further
adjusted in a future rulemaking.
// - to be assessed for potential carcinogenicity by CAG
ifit - to be assessed for chronic toxicity by ECAO
//#// - to be assessed for both potential carcinogencity and chronic
toxicity
NOTE 8: Entries in this column show the basis on which an RQ has been assigned,
coded as follows:
311	- Aquatic toxicity, as assigned under the CWA Section 311.
AQTX - Aquatic toxicity, other than a CWA Section 311 assignment.
T(orl) - Oral mammalian toxicity
T(ihl) - Inhalation mammalian toxicity
T(skn) - Skin (dermal) mammalian toxicity
7-44
-------
CTX	- Chronic Toxicity
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.
BHP	- Biodegradation, hydrolysis, photoloysis.
NOTE 9: The final RQ takes into consideration one or more of the natural BHP
processes. More specifically, the lowest RQ determined by any of the primary
ranking factors has been adjusted upward one level.
NOTE 10: Acetyl bromide reacts violently with water, forming toxic and corrosive
fumes of hydrogen bromide.
NOTE 11: Acetyl chloride reacts vigorously with water, evolving hydrogen chloride
fumes.
NOTE 12: 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 13: Evidence found in OHMTADS and/or "Water-Related Environmental Fate of 129
Priority Pollutants" (EPA-440/4-79-029a) indicates that this hazardous
substance or a constituent of this hazardous substance is bloaccumulated to
toxic levels in the tissue of aquatic and marine organisms, and has the
potential to concentrate in the food chain.
NOTE 14: In the absence of specific data for the hazardous substace listed, oral
toxicity data for the sodium salt is given in brackets.
NOTE 15: Ammonium bifluoride dissolves in water to form hydrofluoric acid.
Therefore it has been assigned a final RQ of 100 pounds based upon the chronic
toxicity assessment for hydrofluoric acid..
NOTE 16: Ammonium fluoride dissolves in water to form hydrofluoric acid.
Therefore, it has been assigned a final RQ of 100 pounds based on the chronic
toxicity assessment for hydrofluoric acid..
NOTE 17: The metallic form of this hazardous substance is currently under
7-45
-------
assessment for either chronic toxicity and/or potential carcinogenicity. Until
such time that the assessment(s) are complete the RQ for this hazardous
substance is the CERCLA statutory RQ of 1 pound. However, reporting of
releases of massive forms of this hazardous substance is not required if the
diameter of the pieces released exceeds 100-micrometers (0.004 inches).
NOTE 18: Antimony pentachloride reacts vigorously with water to form hydrogen
chloride gas.
NOTE 19: Antimony trichloride reacts vigorously with water to form a strong
solution of hydrochloric acid.
NOTE 20: Arsenic trichloride reacts vigorously with water to generate hydrogen
chloride.
NOTE 21: Benzoyl chloride will react energetically with water or steam with
production of heat, toxic and corrosive fumes.
NOTE 22: 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 the container.
NOTE 23: Beryllium chloride reacts vigorously with water with evolution of heat.
Forms beryllium oxide and hydrochloric acid solution.
NOTE 24: Calcium carbide produces acetylene gas on contact with water and may
generate sufficient heat on contact to ignite the acetylene. Based on this
fact, an RQ of 10 pounds has been assigned.
NOTE 25: The final RQ level of Category A (10 lbs) is based on the fact that this
hazardous substance is a strong oxidizer and can readily cause fires.
NOTE 26: No data have been found that permit the ranking of this hazardous
substance. The available data for the acute hazards may lie above the upper
limit for the 5000-pound RQ, but since it is a designated hazardous substance,
the largest assignable RQ is 5000 pounds.
NOTE 27: No data have been found that permit the ranking of this hazardous
substance. However, an RQ level of category D (5000 pounds) has been assigned
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 28: 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 In air or water it
is broken down into hydrochloric and sulfuric acids.
NOTE 29: The range of flash points (F) and boiling points (B) shown in the I/R
7-46
-------
column derives from the three different Cresol isomers, ortho-, meta-, and
para-.
NOTE 30: In addition to its flammability, this hazardous substance 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 31: All cyanides assigned RQs under the CWA Section 311 (40 CFR 117.3) were
placed at RQ level A (10 pounds) on the basis of the aquatic toxicity of the
cyanide ion. The same practice is continued here, with aquatic toxicity values
and CWA Section 311 ratings placed In brackets to indicate that they were not
actually part of the aforementioned regulation, but derive their final RQ from
it nonetheless.
NOTE 32: The CASRN listed for the generic class of cyanides refers to the cyanide
ion only.
NOTE 33: This hazardous substance requires an inhibitor to prevent polymerization.
NOTE 34: The data listed are for 1,2-Dichloropropane.
NOTE 35: 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 ignltability rating as the individual components.
NOTE 36: The final RQ is based on the RQ established for Endosulfan under the CWA
Section 311.
NOTE 37: The final RQ is based on the RQ established for Endrin itself under CWA
Section 311.
NOTE 38: This hazardous substance is the same as 1,2-Dichloroethane.
NOTE 39: This haardous substance is the same as Lindane (58-89-9).
NOTE 40: 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 41: Although this hazardous substance was assigned an RQ of 100 pounds based
on its aquatic toxicity under the CWA Section 311, a final RQ of 10 pounds has
been assigned under CERCLA. The basis for this assignment is aquatic toxicity
data given in 0HMTADS (^50 ~ ^6 hours, 0.64-1.4 ppm Rainbow Trout) and the
Handbook of Acute Toxicity of Chemicals to Fish and Invertebrates (USD0I)
(96-hour LC^q, 0.21 ppm for Bluegill).
NOTE 42: Long-term exposure to mercury vapor is known to induce a degenerative
disease (mercurialism, the "Hatter's Disease") in humans.
7-47
-------
NOTE 43: 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 44: Polymerization of this hazardous substance may occur upon exposure to
heat, oxidizing agents and ultraviolet light.
NOTE 45: There is a wide range of aquatic toxicities reported for napthalene in
OHMTADS, 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 assigned than that established under the CWA Section 311.
NOTE 46: The inhalation toxicity data listed is for red fuming nitric acid.
NOTE 47: An RQ of 1000 pounds was established for nitrophenol under the CWA Section
311, using a single aquatic toxicity data point of 46.3 ppm. However, there
were no specific isomers Identified in making that assignment. A lower RQ of
100 pounds 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 48: Phosphorus oxychloride reacts violently with water and moisture to yield
hydrogen chloride.
NOTE 49: Phosphorus pentasulflde reacts with water to liberate hydrogen sulfide, as
indicated by the symbols I^S in the I/R columns of the table.
NOTE' 50: 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 51: This hazardous substance 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 52: This hazardous substance 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 53: Since Se02 immediately hydrates to ^SeO^ in water, their toxicities are,
for all practical purposes, equivalent.
NOTE 54: Reporting of releases of massive forms of silver is not required if the
diameter of the pieces released exceeds 100-mlcrometers (0.004 Inches).
NOTE 55: Sodium is extremely dangerous in contact with moisture or water, releasing
7-48
-------
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 56: Sodium bifluoride reacts with water liberating heat and forming
hydrofluoric acid.
NOTE 57: This hazardous substance 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 58: The aquatic toxicity data and the final RQ (10 pounds) apply to both
strychnine and its salts. Strychnine is a common name for this material.
NOTE 59: Polymerization may occur if heated above 150°F and can cause rupture of
container. Metal salts, peroxides, and strong acids may also cause
polymerization.
NOTE 60: Sulfur monochloride reacts violently with water to produce heat and
hydrogen chloride fumes. The resulting solution is strongly acidic.
NOTE 61: Vinyl chloride polymerizes in presence of air, sunlight, or heat unless
stabilized by inhibitors.
NOTE 62: This hazardous substance is also known as 1,1-Dichloroethylene.
NOTE 63: The range of flash points (F) and boiling points (B) shown in the I/R
column derives from the three different Xylene isomers, ortho-, meta-, and
para-.
NOTE 64: A metal phosphide will react with water to liberate phosphine as indicated
by the symbols PH^ in the I/R column of the table.
NOTE 65: This hazardous substance will react vigorously with water, liberating
heat, to form hydrogen chloride, and will fume in moist air. An RQ level of
Category D (5000 pounds) has been assigned on this basis.
NOTE 66: The symbol (####) is used to indicate that the Agency is not adjusting the
RQ for radionuclides at this time. The Agency may adjust the RQ for
radionuclides in a future rulemaking. Until that time the statutory 1-pound RQ
is applicable.
NOTE 67: Inhalation toxicities are most commonly measured over a 4-hour period. In
this case, the lowest Inhalation toxicities of 7 and 5 ppm were determined in
only 20 or 30 minutes. A 4-hour exposure would undoubtedly bring these figures
down to well under 4 ppm, corresponding to an RQ category of A (10 pounds).

SECTION 8
DATA TABLES FOR WASTES CLASSIFIED AS HAZARDOUS UNDER RCRA
Detailed data tables showing the basis for the final RQs for the hazardous
wastes following the preferred RQ adjustment methodology and BHP adjustments
as described in Section 2 are presented in Tables 8-1 and 8-2. These lists
are the hazardous substances designated under RCRA Section 3001. The
hazardous substances are commonly 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 8-1 for the P- and U-
wastes and in Table 8-2 for the F- and K- waste streams. The tables include
the data on aquatic toxicity, mammalian toxicity, chronic toxicity,
ignitability, and reactivity upon which the choice of the final RQ is based.
As discussed elsewhere in this report, many hazardous substances remain to be
assessed for chronic toxicity or potential carcinogenicity by the ECAO or CAG,
respectively, and these hazardous substances are appropriately flagged "CHRON
TBA" or "CARC TBA" in the column titled "CARC/CHRON-Note 5." No RQs have yet
been assigned based on potential carcinogenicity and the symbol (If) in the
Final RQ column identifies those substances still to be assessed for potential
carcinogenicity. In those cases where the chronic toxicity assessments are
incomplete the symbol (##) appears in the final RQ column. The symbol (//////)
indicates that both potential carcinogenicity and chronic toxicity are being
assessed. The final RQ listed in Table 2-1 for hazardous substances still
under assessment are the CWA Section 311 or the CERCLA 1-pound statutory RQs
and are identified with an (#)» or (##) to show that they may undergo further
adjustment when assessment is complete.
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:
8-1
-------
(X), (A), (B), (C), (D) - RQ Categories 1, 10, 100, 1000, and 5000
pounds, respectively
CARC TBA - To be assessed for potential carcinogenicity
CHR0N TBA - To be assessed for chronic toxicity
CHR0N* - Hazardous substance is a known chronic toxicant, but since
its RQ has already been adjusted as low as possible
(one pound) on some other basis,, it will not be assessed
for chronic toxicity.
F - Flash point (°F)
B - Boiling point (°F)
311 - The RQ was established on the basis of aquatic toxicity
under the regulations from the CWA Section 311
AQTX - Aquatic toxicity (other than a CWA Section 311 assignment)
CTX - Chronic toxicity
BHP - Biodegradation, hydrolysis, or photolysis
I/R - Ignitability and reactivity
CS - The RQ was assigned on the basis of chemical similarity to
another hazardous substance, in the absence of data for the
primary criteria.
Max - Maximum possible RQ assignment

NOTES FOR TABLE 8-1, COMPREHENSIVE HAZARDOUS SUBSTANCES LIST
PART II - HAZARDOUS WASTES - A. Acute Hazardous Wastes and
B. Toxic Wastes
NOTE 1: The abbreviation No.(ALT.) stands for NUMBER (ALTERNATE). Each line
item is numbered consecutively, with an alternate number, if appropriate,
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 Ignltabllity,
Corrosivity, Reactivity, and Extraction Procedure (EP) 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 regulations, 40 CFR Section 261.10 through 40 CFR Section 261.24.
NOTE 3: Aquatic Toxicity, unless specifically noted otherwise, is given as the
TL 96 (The 96-Hour Median Threshold Limit) for aquatic species. TL.m96 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 TL 96 entry is
followed by a letter Indicating the reportable quantity to which It
corresponds, on the following scale:
RQ (Pounds)
X (1)
A (10)
B (100)
C (1000)
D (5000)
Note that TL and LCcq (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 RQs assigned under CWA Section 311, as given in 40 CFR 117.3. The
detailed listing of aquatic toxicities that form the basis for these
assignments is found In Report No. EPA #440/9-75/009, "Supplement to
Development Document: Hazardous Substances Regulations, Section 311
of the Federal Water Pollution Control Act as Amended 1972," November

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
8-51
-------
the acute oral dose lethal to 50% of the test animal population (LD^)
In milligrams per kilogram of body weight (mg/kg). Test species are
coded as follows:
Hmn = human
Rat = rat
Mus = mouse
Gpg ° guinea pig
Dog = dog
Rbt = rabbit
Thus the entry "Rat-orl:60" Indicates an oral	of 60 mg/kg for
rats.
B.	Dermal Toxicity: These entries are indicated by the code "skn"
immediately following the species code, and are again given as the
acute LD^q j[n milligrams per kilogram of body weight (mg/kg). Test
species are coded the same as given above. Thus the entry
"Rat-skn:60" indicates dermal LD^q 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	(Concentration in air lethal to 50% of the test
animal population) in parts per million (ppm). The exposure time is
also given (H a 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	of 60 ppm for 4 hours for
rats.
D.	Low Lethal Dose or Low Lethal Concentration): These are shown by the
terms "LD- " or "LC^o". ^D. and	are the lowest doses or
concentrations known to have haa lethal effect on the test species.
Thus the entry Rat-ihl LC^q:60/4H indicates an inhalation LC^q of 60
ppm for 4 hours for rats.
Note: Human LC 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 RTECS
(see NOTE 3B above).
E.	Toxic Dose (or Concentration): These are shown by the designation TD
(for dose) or TC (for concentration). This means that the data
represents a dose at which signs of toxicity other than immediate
death were noted.
Each toxicity entry is followed by a letter indicating the RQ category
to which it corresponds, on the following scales:

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 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 hazardous substances that have previously
been identified by the EPA as having an appreciable chronic or
subacute effect, as described in any of the following documents:
1.	"The Registry of the Toxic Effects of Chemical Substances," RTECS,
accessed as a machine-searchable data base via the CIS. RTECS now
contains information on over 63,000 chemical substances.
RTECS is also available in hard copy, the latest being DHHS
(NI0SH) Publication No. 83-107, "1981-82 Registry of the Toxic
Effects of Chemical Substances," Volumes 1, 2, and 3. U. S.

Harold V. Wolf (Editors), Publication 2-A. This document was
prepared by the State of California, The Resources Agency of
California, State Water Quality Control Board in 1963. It is
essentially a broad reference document used to support all aspects
of water quality control in the State of California during the
period 1952 (First Edition) through the early 1970's.

This document was prepared in 1978 by the California Department of
Food and Agriculture, and was initiated as the result of the
California Environmental Quality Act and a related Opinion
generated by the Attorney General, State of California.
C.	The entry "CHR0N*" indicates that the hazardous substance is known to
have a chronic effect, but since its RQ has already been set at the
1-pound 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 CAG,
and therefore the statutory RQ of the material applies until 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:
1. "First Annual Report on Carcinogens." This report was issued In
July 1980 by the Department of Health and Human Services (DHHS).
It was prepared by the National Toxicology Program, U. .S. Public
Health Services. This report was mandated under an amendment to
Section 301(b)(4) of the Public Health Service Act, Public Law
95-622, signed November 8, 1978.

September 1979 by the International Agency for Research on Cancer.
5.	"Monographs Supplement 4. Chemicals, Industrial Processes and
Industries Associated with Cancer in Humans." This report was
issued in 1982 by the IARC, and is essentially an updated version
of Monographs Supplement 1.
NOTE 6: I/R stand for Ignitability 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 ignltable.
B. 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 RQ category to which it corresponds, based on the
following scales:
8-55

Association, Boston, MA, 1978.
NOTE 7: Entries under this column show the RQ that was assigned under CWA
Section 311 (40 CFR 117.3, 44 FR10279-10283, February 16, 1979).
NOTE 8: Entries in this column are the lowest RQs derived from the individual
rankings shown under the Aquatic Toxicity, Mammalian Toxicity, Chronic
Toxicity, and/or I/R columns or (b) the entries are flagged as follow to
indicate that the hazardous substance is under assessment for potential
carcinogenicity and/or chronic toxicity, and the statutory RQ will be
further adjusted in a future rulemaking.

NOTE 9: Entries in this column show the basis on which an RQ has been assigned ,
coded as follows:
311	- Aquatic toxicity, as assigned under the CWA
Section 311.
AQTX - Aquatic toxicity, other than a CWA Section 311 assignment.
T(orl) - Oral mammalian toxicity
T(ihl) - Inhalation mammalian toxicity

-------
T(skn)
- Skin (dermal) mammalian toxicity
CTX	- Chronic Toxicity
I
- Ignitability
R

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-pound RQ has been made on
the basis of this being the largest value possible
to assign.
BHP
- Biodegradation, hydrolysis, or photolysis.
Note 10: Evidence found in OHMTADS and/or "Water-Related Environmental Fate
of 129 Priority Pollutants" (EPA-440/4-79-029a) indicates that this
hazardous substance, or a constituent of this hazardous substance 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 The final RQ takes into consideration one or more of the natural
BHP processes. More specifically, the lowest RQ determined by any of
the primary ranking factors has been adjusted upward one level.
NOTE 12: A metal phosphide will react with water to liberate phosphine, as
indicated by the symbol PH^ in the I/R column of the table. The final
RQ of this hazardous substance is thus set equal to the RQ for
phosphine (P096), at a value of 100 pounds.
NOTE 13: There are two arsenic acids, one identified by the CASRN
7778-39-4, and having the synonyms arsenic acid (H-AsO,), arsenic acid
solution, arsenic acid liquid, and orthoarsenic acid. The other, with
CASRN 1327-52-2, has the synonyms arsenic acid liquid and arsenic
anhydride. Data on the latter may be found in OHMTADS, while the
toxicity of the former may be found in RTECS.
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. However, the alkyl
arsines, as a class, are pyrophoric. (See also Note 14.)
8-57
-------
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 the
container.
NOTE 17: All cyanides assigned RQs under CWA Section 311 (40 CFR 117.3)
were placed at RQ level A (10 pounds) on the basis of the aquatic
toxicity of the cyanide ion. The same practice is continued here.
NOTE 18: The CASRN listed for the generic class of Cyanides refers to the
cyanide ion.
NOTE 19: Data are presented only for the cresol itself; however, the final
RQ also applies to the salts.
NOTE 20: AN RQ of 1000 pounds was established for Dinitrophenols under CWA
Section 311 (40 CFR 117.3). A final RQ of 10 pounds has been assigned
under CERCLA on the basis of new aquatic toxicity data.
NOTE 21: The entry "Trichloromethylmercaptan" (p 118) in 40 CFR 261.-33 has
been taken to mean perchloromethylmercaptan, otherwise known as
trichloromethanesulfenyl chloride.
NOTE 22: Data are presented only for nicotine itself; however, the final
RQ also applies to the salts.
NOTE 23: 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 IV oxide.
NOTE 24: The final RQ level of Category A (10 pounds) assigned for this
hazardous substance is based on the fact that it is a strong oxidizer
and can readily cause fires.
NOTE 25: The aquatic toxicity of this hazardous substance is listed as less
than 0.1 on the basis of its silver content; silver is extremely toxic
to aquatic organisms.
NOTE 26: A final RQ level of B (100 pounds) is assigned on the basis of
reactivity, Inasmuch as the mishandling of this hazardous substance
might result in the release of hydrogen sulfide, which has been placed
at the 100-pound RQ level.
NOTE 27: The aquatic toxicity data and the final RQ (10 pounds) apply to
both strychnine and its salts. Strychnine is a common name for this
hazardous substance.
NOTE 28: This hazardous substance was identified as the selenite in the
8-58
-------
published RCRA regulations (40 CFR 261.33) RTECS 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 CIS) gives the name Thallium Selenide, and the
CASRN shown here. It appears that selenide is the correct term.
NOTE 29: Chloral rapidly hydrates upon ingestion to form chloral hydrate.
The toxicity value shown is that of the hydrate.
NOTE 30: No data have been found to permit the ranking of this hazardous
substance. The available data for the acute hazards may lie above the
upper limit for the 5000-pound RQ, but since it is a designated
hazardous substance, the largest assignable RQ is 5000 pounds.
NOTE 31 Acetyl chloride reacts vigorously with water, evolving hydrogen
chloride fumes.
NOTE 32: 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 33: It is highly likely that the intent in the RCRA regulations was to
list all common toluene dilsocyanate Isomers. Benzene,
2,4-diisocyanatomethyl (CASRN 584-84-9), which is the same as Toluene
dilsocyanate (or Toluene,2,4-diisocyanate) and which Is also the more
common item of commerce (U223). The generic Benzene,
1,3-diisocyanatomethyl has a CASRN of 26471-62-5 and Benzene,
l,3-diisocyanato-2-methyl or 2,6-Toluene dilsocyanate has the CASRN
91-08-7.
NOTE 34: 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 35: Common name for this material is Epichlorohydrin.
NOTE 36: Coal tar cresote is Identified by the CASRN 8001-58-9, and data
presented is for this material. No data were found that would allow
rating of beechwood creosote, CASRN 8021-39-4.
NOTE 37: The range of flash points (F) and boiling points (B) shown in the
I/R column derives from the three different Cresol isomers, ortho-,
meta-, and para-.
NOTE 38: Data are presented only for the free acid; however, the assigned
RQ also applies to salts and esters.
8-59
-------
NOTE 39: This hazardous substance is the same as Bis(2-chloroethyl)ether.
NOTE 40: Data on the aquatic toxicity for 2,6-Dichlorophenol may be found
in OHMTADS under the entry for 2,4-Dichlorophenol.
NOTE 41: Common name for this hazardous substance is Hydrazobenzene.
NOTE 42: The oral toxicity value shown is for the sodium salt; however,
the final RQ applies to the free acid and esters as well.
NOTE 43: This hazardous substance polymerizes in the presence of air,
sunlight, or heat unless stabilized by inhibitors.
NOTE 44: Inhalation toxicities are most commonly 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 pounds).
NOTE 45: Long-term exposure to mercury vapor is known to induce a
degenerative disease (mercurialism, the "Hatters's Disease") in humans.
NOTE 46: 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 47: This hazardous substance has been assigned an RQ value based on
its very close similarity to methyl bromide and bromoform, which have
final adjusted RQ levels of C (1000 pounds), and B (100 pounds). A
final RQ of 1000 pounds was selected.
NOTE 48: Common name for this hazardous substance is carbon tetrachloride.
NOTE 49: Polymerization of this hazardous substance may occur upon exposure
to heat, oxidizing agents and ultraviolet light.
NOTE 50: There is a wide range of aquatic toxicities reported for
naphthalene in OHMTADS, ranging down to 1 ppm for certain species and
conditions. Similarly, RTECS reports an aquatic toxicity for
naphthalene of 1-10 ppm. On this basis, a lower RQ has been assigned
than that established under CWA Section 311.
NOTE 51: Phosphorus sulfide reacts with water to liberate hydrogen sulfide
as indicated by the symbol ^S in the I/R columns of the table.
NOTE 52: The RCRA regulation (40 CFR 261.33) lists selenious acid and
selenium dioxide under the same number (U204). However, these are two
separate and distinct hazardous substances and the CASRN has been
provided for each. However, the distinction is of little consequence,
8-60
-------
since SeOj immediately hydrates to HjSeO^ in water, so that their
toxicities are, for all practical purposes, equivalent. Brackets
around entries for these two hazardous substances indicate where such
equivalent data has been assigned from one hazardous substance to the
other.
NOTE 53: Mishandling of this hazardous substance could lead to the
liberation of I^S.
NOTE 54: The range of flash points (F) and boiling points (B) shown in the
I/R column derives from the three different Xylene Isomers, ortho-,
meta-, and para-.
NOTE 55: Inhalation toxicities are most commonly measured over a 4-hour
period. In this case, the lowest inhalation toxicities of 7 and 5 ppm
were determined in only 20 or 30 minutes. A 4-hour exposure would
undoubtedly bring these figures down to well under 4 ppm, corresponding
to an RQ category of A (10 pounds).

NOTES FOR TABLE 8-2
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 CASRN of Its constituents. Where the constituents
are Indefinite or generic in nature, and no CASRN 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 regulation, 40
CFR 261, Appendix VII. 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 (EP) Toxicity, respectively.
This represents the reasons why a waste stream was listed as a hazardous waste
under the RCRA. They are explained in detail in the RCRA regulations, 40 CFR
261.10 through 261.24
NOTE 3: With few exceptions, the constituents of the F and K list waste streams
have been previously evaluated and a final RQ determined. Entries in this
column refer to the Specific Chemical Waste on the U- or P- list in Table 8-1
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 8-1.
NOTE 4: Entries in this column show the RQ that was assigned under the CWA Section
311 (40 CFR 117.3).
NOTE 5: Entries under this column are either (a) the lowest RQs derived for the
constituents of the F and K list waste streams as previously evaluated (see
Table 7-1 and 8-1 where that evaluation was made) or (b) the entries are
flagged as follows to Indicate that the hazardous substance is under assessment
for potential carcinogenicity and/or chronic toxicity, and the statutory RQ
will be further adjusted in a future rulemaking.
# - to be assessed for potential carcinogenicity by CAG
//// - to be assessed for chronic toxicity by ECAO
////// - to be assessed for both potential carcinogenicity and
chronic toxicity.
F list wastes F001 - F005 may consist of any one of their constituents alone,
and therefore a numerical final RQ in pounds is shown for each constituent of
8-85
-------
each waste, and the lowest of these RQs 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 final
RQ in pounds is shown opposite both the constituents and the description of the
waste itself. This latter final RQ for the waste, in this case, 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 assigned
coded as follows:
311 - Aquatic toxicity, as assigned under CWA Section 311.
AQTX - Aquatic toxicity, other than a CWA Section 311 assignment.
T(orl) - Oral mammalian toxicity
T(ihl) - Inhalation mammalian toxicity
T(skn) - Dermal (skin) mammalian toxicity
CTX - Chronic toxicity
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-pound RQ has been made on the basis of this being
the largest value possible to assign.
BHP - Biodegradation, hydrolysis, or photolysis.
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
RQ. See Note 5, above.
NOTE 7: A maximum RQ (5000 pounds) has been assigned to the
component 1,1,2-Trichloro-l,2,2-tri-fluoroethane on the basis of the following
data:
Rat = 43,000 mg/kg (oral)
LC^q Rat = 87,000 ppm/6 hours (inhalation)
8-86
-------
NOTE 8: The assigned RQ takes into consideration one or more of the natural
degradation processes of biodegradatlon, 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 pounds) has been assigned for ethylbenzene on the
basis of the following data:
Flash point = 59°F
Boiling point = 277°F
NOTE 10: All cyanides assigned RQs under CWA Section 311 (40 CFR 117.3), were
placed at RQ level A (10 pounds) 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 pounds) has been assigned for the component
1,2,3,-Trichloropropane on the basis of the following data:
LD50 Rat = 320 mg/kg (oral)
LC^q = 1000 ppm/4 hours (inhalation)
NOTE 12: An RQ level of C (1000 pounds) has been assigned for the component
2,3-Dichloro-n-propanol on the basis of the following data:
Rat = 90 mg/kg (oral)
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 pounds) has been assigned for the component
Diphenylamine on the basis of the following data:
LD50 Gpg ° 300 mg/kg (oral)
NOTE 15: An RQ level of B (100 pounds) has been assigned for the component
paraphenylenediamlne on the basis of the following data:
TL^(48) Goldfish =5.7 ppm
Rat = 80 mg/kg (oral)
8-87
-------
NOTE 16: These esters are assumed to be composed of disulfoton and/or its
analogues, and accordingly an RQ level of X (1 pound) has been assigned based
on the RQ assignment of 1 pound given to disulfoton under CWA Section 311.
NOTE 17: These esters are assumed to be composed of phorate and/or its analogues,
and accordingly an RQ level will be proposed 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.

PREFACE
Ourlng the past three years the Environmental Criteria and Assessment
Office, Cincinnati (ECAO-CIn) of the U.S. EPA has developed a method to rank
chemicals based on chronic toxicity data. This ranking system reflects two
primary attributes of every chemical: the minimum effective dose and the
type of effect elicited at that due. Although based on observed toxicity
data, It Is not considered to be a health risk assessment.
The purpose for developing this chronic toxicity ranking system was to
provide the U.S. EPA with the technical background required to adjust the
RQs of hazardous substances designated in Section 101(14) of the Comprehen-
sive Environmental Response, Compensation and Liability Act of 1980 (CERCLA
or "Superfund"). This ranking system has undergone a limited peer review
and a public review. It may have applications to other areas of Interest to
the U.S. EPA and other regulatory agencies where ranking of chemicals based
on chronic toxicity 1s desired.

1. INTRODUCTION
The purpose for developing this chronic toxicity ranking system was to
provide the U.S. EPA with the technical background required to adjust the
RQs of hazardous substances designated 1n Section 101(14) of the Comprehen-
sive Environmental Response, Compensation and Liability Act of 1980 (CERCLA,
or "Superfund"). Section 103 of CERCLA requires Immediate notification from
any person 1n 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) of CERCLA 1s 1 pound unless a different RQ has been established pur-
suant to Section 311(b) of the Federal Water Pollution Control Act. This Is
the statutory RQ for each hazardous substance unless and until the Admin-
istrator of the U.S. EPA promulgates regulations establishing that quantity
of any hazardous substance the release of which shall be reported pursuant
to Section 103 of CERCLA. CERCLA also permits the U.S. EPA to establish a
single RQ for each hazardous substance regardless of the environmental
medium Into which the substance 1s released.
The strategy of the Office of Emergency and Remedial Response (OERR) of
OSWER 1s to adjust the Section 101(14) statutory RQs using six primary
criteria (1gn1tab111ty, reactivity, carcinogenicity, aquatic toxicity,
acute mammalian toxicity (oral, dermal. Inhalation) and chronic toxicity)
and three other factors (blodegradatlon, hydrolysis and photolysis).
(Chronic toxicity, for the purposes of this report, 1s 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 1s set up corresponding with RQ values of 1. 10, 100,
1000 and 5000 pounds (X, A, B, C, D). Since this five-tiered system was
0721B

successfully used 1n the CWA and the regulated cotnnunHy 1s familiar with
1t, CERCLA uses this methodology. Unlike the CWA", CERCLA 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
CERCLA was based on the precedence established 1n assigning RQs pursuant to
the CWA, Instead of using aquatic toxicity as the sole criterion for estab-
lishing RQs, health and welfare effects for other media were also used to
adjust the RQs. Each hazardous substance Is evaluated according to the pri-
mary criteria and an RQ value 1s- determined for each applicable criterion.
The "primary criteria* RQ for each hazardous substance Is the lowest value
of all the applicable criteria.

2. CHRONIC TOXICITY RANKING SYSTEM
The chronic toxicity ranking system reflects two primary attributes of
each chemical:
1.	The MED levels for a given effect following chronic exposures
(mg/day for 70 kg man) by alternative environmental media (air,
water).
2.	Type of effect at the MED (e.g., liver necrosis, teratogeni-
city, etc.).
The dose rating for a given chemical 1s based upon the MED transformed
to values ranging from 1-10 using the graph given In Figure 2-1. 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. Similarly, the rating for the
observed effect at a given dose for a given chemical will range from 1-10
depending on severity using Table 2-1, with 10 being the most severe. These
values must be assigned on a chemical-by-chemical basis.
A final composite score (CS) is determined by multiplying the dose rat-
ing by the effect rating. The possible range of CSs is thus 1-100. Using
this scheme, only those compounds eliciting what are judged to be the most
severe effects at low levels of exposure would be assigned high CSs; com-
pounds that elicit minimal effects at high doses would be assigned low CSs.
The following text gives step-by-step details for this procedure:
1.	Identify subchronlc or chronic NOAELs, LOAELs or FELs* based on
animal or human data from the available literature. Note the
dose/exposure and the effect.
2.	Convert all NOAELs, LOAELs and FELs to units of mg/kg/day.
Inhalation, dietary or drinking water exposure data will be
converted to units of mg/kg/day doses based on the methods
outlined previously (U.S. EPA, 1980).
3.	If the NOAEL, LOAEL or FEL is based on subchronlc exposure, a
corresponding chronic value will be estimated by dividing the
subchronlc value by 10 or less. This is supported experi-
mentally by Hell and NcCollister (1963) and McNamara (1976).

« If adequate chronic data are available, disregard NEDs
based on subchronlc data.
If more than one MED remains, select the NED which 1s based
on the "best" data.
• If considerations of data quality do not lead to the selec-
tion of a single MED, the NED resulting In the highest CS
for a given route will be used.
9.	Having selected a single NED and derived a CS for each route of
exposure, the NED used to rank the chemical will be the MEO

3. APPLICATION OF THE METHODOLOGY
To date, -260 compounds have been assessed using the methodology
described 1n Chapter 2. In the final evaluation, Insufficient data were
available to derive CSs on 81 compounds, CSs were derived by analogy for 47
compounds, and CSs were directly derived from experimental data on the 116
remaining compounds. Histograms were constructed from preliminary evalua-
tions showing the distribution of RV.s, RV s and maximum CSs, and are
d e
given 1n Figures 3-1, 3-2 and 3-3, respectively. Although the final evalua-
tion has changed several totals, the discussions concerning these histograms
and, more Importantly, the conclusions reached are the same.
A reasonably symmetric distribution of CSs was obtained (see Figure
3-3). Histograms of the RV^s and RVgs were generated to better under-
stand the distribution of CSs and to suggest ways 1n which the methodology
could be modified to account for the-available- data. As Indicated In Figure
3-1, the distribution of RV^s 1s skewed markedly toward the lower values.
While this partially reflects the distribution of doses 1n all the available
data, many of the doses given an RV^ of 1 were well 1n excess of 1000
mg/day, suggesting that It may be desirable to expand the RV^ scale, at
least at the lower limit. In the distribution of RVes, the predominance
of RVgs of 10, which Indicate mortality or teratogenic effects without
signs of maternal toxicity, appears to reflect the nature of the data on the
105 compounds and may not be of substantial use In modifying the effects
rating scheme. All RV s derived for the 105 compounds, not just those
e
associated with the maximum CS, are being reanalyzed to better evaluate this
assertion.

In addition to examining the distribution patterns of CSs, RV^s and
RVes, 1t was also determined If any correlation existed between reported-
acute and calculated-chronic toxicity values and If any structural correla-
tions could be found vs. the chronic toxicity values. These determinations
were deemed Important since acute mammalian toxicity 1s a primary criterion
1n establishing toxicity rating schemes, and the Inclusion of chronic toxi-
city might possibly be redundant. This latter concern 1s possibly Justified
given the relationships between acute and chronic toxicities noted by
McNamara (1976), Well and McColllster (1963) and Well et al. (1969). Conse-
quently, for the 105 compounds on which maximum CSs were directly derived,
the LOgQ 1n experimental mannals was identified from the Registry of Toxic
Effects of Chemical Substances (NIOSH, 1982) and converted to approximate
human LDjqS using the cubed root of the body weight ratios as specified 1n
point 4, Chapter 2. Preliminary results of these analyses are given In
Figures 3-4, 3-5 and 3-6 for aromatlcs, allphatlcs and Inorganics, respec-
tively. Although an attempt Is being made to more critically review the
acute toxicity data, and statistical analyses will be conducted, no correla-
tions between maximum CSs and minimum LD^s are apparent. That 1s to say,
the chronic toxicity of a series of chemicals cannot necessarily be pre-
dicted from acute toxicities. This Is a well established principle 1n the
field of toxicology. Therefore, the use of chronic toxicity as a ranking
tool Is not redundant.
Although work on structural correlations Is 1n a very preliminary stage.
Figure 3-7 Indicates no apparent correlation between maximum CSs and Upo-
ph1l1c1ty for 21 substituted benzenes. In this figure, log of the octanol/
water partition coefficient given by Hansch and Leo (1981) was used as the
Index of Hpophl lldty. Analyses of other structural parameters are
currently being conducted.

4. SOKE CONCEPTUAL CONSIDERATIONS
The development of the quantitative rating scheme for effects (see Table
2-T) and the combination of this scheme with a quantitative estimate of dose
(see Figure 2-1) represent a potentially useful Innovation 1n the analysis
and assessment of chronic toxicity data. The effects rating scheme Is based
an a combination of biochemical, histologic, physiologic and gross effects
arranged In Increasing order of severity. While the rating values assigned
to each type of effect are essentially arbitrary, rating values of 1 to 3 or
4 have been generally regarded as NQAELs. 5-7 as LOAEls and 7-10 as FELs.
In an attempt to allow for the necessary scientific Judgment, the descrip-
tion of the effects 1s Intentionally not too detailed. Although some addi-
tional modifications and expansions of the scheme may be desirable, the
application of the scheme to date suggests that 1t would be a mistake to
attempt to catalogue every possible specific effect which chemicals can
Induce and to associate each effect with a quantitative value. Also, the
ranking scheme Is not organ specific. While the ICRP (1977, 1979) has
addressed the problem of organ sensitivity to specific radionuclides, and
their approach may be useful In predicting the most sensitive organ for cer-
tain radionuclides, the effects rating scheme presented In Table 2-1 1s
Intended to be applicable across target sites.
Nonetheless, the variation In organ sensitivities 1s an Important factor
In defining the HEO associated with a given dose level for a particular
toxicant. This 1s Illustrated In Figure 4-1, hypothetical data In which
NOELs, NOAELs, LOAELs and FELs are plotted on a RVd vs. RVq diagram. At
low doses (I.e., high RVds) only NOELs are observed. As the dose In-
creases (I.e., the RVtf decreases) effect ratings become Increasingly high.

However, at a given effect level, multiple points can be expected as the
dose Increases with the point furthest to the right representing the roost
sensitive organ or species or Increasing incidence of the effect. The slope
of the line draw? to the right of the effect level points and Intersecting
the X-axis to the left of the NOELs represents the maximum Increase In the
severity of effect with Increasing dose and may be termed the apparent
severity slope. However, as illustrated 1n Figure 4-2, the apparent sever-
ity slope may be a composite of severity slopes for specific organs and/or
species.

5. MODIFICATION ANO APPLICATIONS
The basic methodology outlined 1n Chapter 2 of this report was developed
In response to a specific need. Having applied the methodology to -260
compounds, explored some of the conceptual considerations Inherent In the
methodology, and received preliminary comments from scientists both within
and outside of the Agency, the following modifications have been considered:
1.	Oerlve the CS as the sum rather than the product of RVg and
RVe.
2.	Modify the dose rating scheme to cover a wider range of doses.
As Indicated 1n Figure 3-1 and discussed 1n Chapter 3 of this
report, several studies from which maximum CSs were derived
Involved dose levels well 1n excess of 1000 mg/day, yet were
still assigned the minimum RV^ of 1. The revision currently
under consideration would cover 10 log dose units from 10*
mg/day yielding an RV^ of 1 to 10~4 mg/day yielding an
RVd of 10.
3.	Review and utilize data on pharmacokinetics and other relevant
data to obtain more reasonable estimates of absorption from
orat and Inhalation routes. The current approach assumes 50%
absorption from Inhalation exposures and 100% absorption from
oral exposures. These assumptions were made rather than review-
ing absorption data 1n an effort to minimize the cost of this
project. However, these assumptions may be misleading particu-
larly for metals.
4.	Modify the effects rating scheme giving more specific guidance
and/or altering some of the criteria.
In addition, the application of the methodology has suggested that the
RVe vs. RV^ plot may be useful to other Agency Offices 1n the estimation
of NOELs or NOAELs used In the derivation of ADIs. Kushner et al. (1983)
have recently reviewed the use of AOIs In Superfund implementation, and
Stara and coworkers (Stara et al.. I960, 1961; Oourson and Stara, 1983) have
reviewed more general problems with the estimation and application of ADIs
1n the regulatory process. Two problems Involving the use and derivation of
AOIs may be at least partially alleviated by using the RVfl vs. RVg plot.
0721B
B-28
09/19/84
-------
First, the Agency frequently has been criticized for not using all of the
available data In estimating the NOAEL from which ADIs are derived. Using
the RVfi vs. RV^ plot along with an appropriate statistical method for
estimating the apparent severity rlope and the x-lntercept (I.e., maximum
NOEL), all of the available subchronlc and chronic data could be used.
Second, examples have been encountered where no suitable NOAELs or LOAELs
are available from which an AOI could be derived. In such cases, data on
FELs and NOELs could be used to estimate either the maximum NOEL or a suit-
able NOAEL (e.g., dose associated with an RVe of 1 or 2). Again, this
would be dependent on the development of an appropriate mathematlc model to
estimate the severity slope and x-1ntercept.
In addition to these 1nmed1ate applications, 1t may be desirable to con-
sider expanding the RV^ and RVe plot to include axes for duration of
exposure, species and Incidence of response. This, however, would be a very
complex undertaking that should await further development and applications
of the basic RV vs. RV. plot.

Appendix D
ALTERNATE METHODOLOGIES FOR RQ ADJUSTMENTS AND
ASSIGNMENTS TO THE CERCLA 101(14) LIST
A number of possible methodologies for determining RQ values for the
designated hazardous substances were briefly discussed earlier (Section ES,
pp. ES-5 through ES-12). The reasons for rejecting all but the preferred RQ
adjustment methodology are self-evident for the majority of those
methodologies and such discussions will not be repeated here. However, one of
the methodologies, namely the use of a hazard index (HI), was subjected to an
extensive study before it was finally eliminated. His 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
CERCLA (e.g, the "Mitre Model" used to rank hazardous waste sites). The
discussion that follows provides a detailed summary of studies exploring the
possibility of developing a HI suitable for RQ assignments.
HAZARD INDEX DEFINITION AND APPLICATION
A HI is a scoring system designed to assess the relative potential threat to
human health and to the environment of hazardous 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
hazardous substances 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 hazardous substance relative to other hazardous substances processed
through the same equation.
D-3
-------
Analytical Problem
Although the logic for rating hazardous substances appears relatively simple,
there are a great many complications that exist and that operate to limit the
development of a HI. 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 HI. Finally, inherent in the
formulation of a HI is the need to consider all relevant criteria, and if
possible, choose only those that are mutually independent of each other.
However, when dealing with intrinsic properties of chemical substances, mutual
independence of hazard criteria is difficult, if not impossible, to determine.
For example, a hazardous substance 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
Five alternate algorithms were 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 various
extents in development of each of the four alternative algorithms fall into
four general categories, as outlined below:
A.	Health Effects
o	Potential Carcinogenicity
o	Mutagenicity
o	Teratogenicity
o	Toxicity (human and mammalian)
B.	Welfare Effects
o Flammability
D—4
-------
o	Explosivity
o	Corrosivity
o	Reactivity
o	Aquatic Toxicity
C.	Aggravating Characteristics
o Persistence
o Bioaccumulation
o Toxic Combustion Products
D.	Mitigating Physical and Biological Transformation Characteristics
o	Hydrolysis
o	Photolysis
o	Oxidation
o	Biodegradation
E.	Environmental Mobility
o Volatility
o Solubility
Algorithm I was designed to rank hazardous substances entirely on major
potential health effects. It was a simple additive algorithm comprised of
five components:
HI = (Potential Carcinogenicity) + (Mutagenicity) +
(Teratogenicity) + (Human Toxicity) +
(Mammalian Toxicity)
Algorithm Ila was slightly more sophisticated in that, in addition to health
effects, it permitted evaluation of other adverse effects that might occur
(fire, explosion, reaction) and aggravating characteristics (persistence and
bioaccumulation). In addition, this particular algorithm allowed evaluation
of mitigating effects. The basic form of the algorithm was additive and
consisted of the following simplified terms:
HI = Health Effects + Welfare Effects + Aggravating Effects
- Mitigating Effects
D-5
-------
Algorithm lib used the sane rankings as employed in that immediately
preceding, but used weighting factors (coefficients) in an attempt to balance
the impact of the individual terms on the final index. The form was as
follows:
HI = (Health Effects) + W2 (Welfare Effects)
+ W3 (Aggravating Effects) - W4 (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 was an extension of the second. It was comprised of essentially
the same rating factors; however, the mathematical approach was different.
Rather than being strictly additive, it incorporated multiplicative
arrangements to arrive at a final rating. This algorithm took the following
form:
HI = (Health Effects) x (Aggravating Health Factors)
+ (Welfare Effects) x (Aggravating/Mitigating
Transformation Properties)
Algorithm IV 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 TV was
as follows:
HI = (Health Effects) + (Welfare Effects) +
(Environmental Mobility) + (Aggravating Characteristics)
D-6
-------
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 hazardous substance with the highest HI value was taken to be
the most hazardous and therefore was assigned a relative ranking of 1. The
hazardous substance with the next highest HI value was assigned a relative
ranking of 2, and so on. If two or more hazardous 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:
Hazardous Substance

12
1
Carbon Disulfide
11
2
Chloroform
11
2
Phosphorus (White)
11
2
Acrolein

5
The final relative rankings for the 27 hazardous substances by all algorithms
is given in Table D-l. The rankings presented in Table D-l highlight the
problems with HI and reemphasize the complications pointed out earlier. It is
immediately evident that there is no consistency in the way the indices rate
different hazardous substances.
In conclusion, it does not appear that standardized HI 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 recommended.
