INTRODUCTION
This background document explains the basis for regulations
concerning discarded commercial products, which are described
and listed in §261.33 and for which exclusion levels are
established in §261.5. Commercial chemical products or
manufacturing chemical intermediates are divided into two
categories: those which are acutely hazardous and subject to
stringent exclusion levels; and those which are hazardous
and which axe regulated in the same manner as other hazardous
wastes. These regulations concern commercial chemical products,
and associated off-specification chemical products, spill
cleanup residues and debris. For acutely hazardous chemicals,
the regulations also cover containers and inner liners which
contained the acutely hazardous chemicals.
-------
PROPOSED RULES
Synopsis of Proposed Rules
Appendices III, IV, and V of the Proposed Rules and
Appendix XII of the Supplemental Proposed Rule listed approx-
imately 300 toxic chemicals. Appendix III listed 24 pesticides
which either had been cancelled for some or all uses under the
Federal Insecticide, Fungicide and Rodenticide Act (FIFRA)
or were undergoing RPAR (rebuttable presumption against
registration) under FIFRA. Appendix IV listed 157 chemicals
that were listed as Poison A, Poison B or ORM-A materials in
the Department of Transportation regulations under 49 CFR
Parts 172 and 173. Appendix V listed the remainder of the 129
toxic priority pollutants (not already included on Appendices
III or IV) for which effluent guidelines limitations were being
developed under the Clean Water Act. Appendix XII listed 33
chemicals that had been found to be human carcinogens or
potential human carcinogens by the International Agency for
Research on Cancer.
By reference to the appendices these hazardous chemicals,
if discarded, were listed as hazardous wastes in §250.14(a)
of the Proposed Rules. In addition, §250.14(a) also provided
that off-specification species of these toxic chemicals, if
discarded; the emptied containers from these chemicals, if
not triple rinsed; and the clean-up residues and debris from
spills of these chemicals were hazardous wastes.
-------
In adopting these chemicals EPA relied heavily on the work
done by other offices in the Agency, or by other, agencies. The
Agency believed that each listed chemical possessed toxic
properties: that they either exhibited the proposed toxicity
characteristic or that they were toxic organic or mutagenic,
carcinogenic or teratogenic substances. The Agency had
not, however, evaluated each substance with reference to
either the characteristic of hazardous waste or criteria
for listing .
These chemicals were proposed to be hazardous wastes if
(1) they, themselves, were discarded, (2) off-specification
species of these chemicals were discarded, (3) containers
which formerly contained these chemicals were discarded or
(4) clean-up residues and debris from spills of these chemicals
were discarded. Importantly, these chemicals were not listed
to be used to cause solid wastes derived from manufacturing
processes (and which might only contain very low concentrations
of these chemicals) to be listed as hazardous wastes'. As is
noted later in this document, this point was misunderstood
by many commenters.
Section 250.29(a) of the Proposed Rules provided that any
retailer or any person who produced and disposed of no more
than 100 kilograms of hazardous waste in any one month would
not be subject to the full Subtitle C regulation if the waste
was disposed of in a Subtitle D facility. The effects of this
exemption were that (1) any retailer could discard any and all
quantities of these chemicals or the associated materials
-------
described above without being subject to regulation and (2)
any small quantity generator could discard as much as 100
kilograms per month* of these chemicals or the associated
materials without being subject to the Subtitle C regulations.
Consequently, these chemicals and associated materials effec-
tively were hazardous wastes only if generated by non-retail
and large-quantity (greater than 100 kilograms per month)
generators .
* Provided he discarded no other hazardous wastes. The
exemption, as proposed, covered total quantity of hazardous
wastes. Hence, only 100 kilogram of the 295 chemicals
and other hazardous wastes, in aggregate, in any one
month, were excluded. The final exlcusions also relate to
total quantities of hazardous waste.
-------
Rationale for Proposed Rules
In the development of the Proposed Rules, a number of
persons, pointed out that an important part of the hazardous
waste generated throughout the country were commercial chemicals
that normally are not discarded but, for a variety of reasons,
are occasionally discarded.
Examples given were reduction of inventory, changes in
product line, cancellation of pesticides, no further use for
remaining stocks and residuals from batch-process manufacturing
or formulating operations. In particular operators of solid
waste management facilities indicated that some "wastes"
which they receive are discarded pure chemicals as opposed
to typical wastes from 'manufacturing or other activities.
These same persons also indicated that off-specification
chemicals are sometimes discarded. The Agency recognized
that some of these chemicals and off-specification materials
were toxic and, even though discarded only occasionally (and
usually in small amounts,) could pose a substantial hazard
to human health or the environment.
-------
In concert with this advice, the Agency concluded that pesti-
cides that had been cancelled or were being reviewed for possible
cancellation action (Appendix III of the Proposed Rules) and
Poison A, Poison B and ORM-A materials that are regulated by
the Department of Transportation because of their threat to
safety (Appendix IV) constituted chemicals that were toxic
and, if discarded, could pose substantial hazard to human
health or the environment. It further concluded that the
toxic pollutants being regulated under §307(a) under the
Clean Water Act (Appendix V, unless already listed in Appendix
III or IV,) and known or suspected human carcinogens (Appendix
XII) were hazardous materials that posed significant risk to
human health or the environment, if discarded. Consequently,
these chemicals were listed in the Proposed Rules and were
established to be hazardous wastes if they or their off-
specification species were discarded.
The Agency also learned that a significant part of solid
wastes was empty containers, including containers that had contained
toxic chemicals. These empty containers typically contain
chemical residues because they had not been rinsed or otherwise
decontaminated. It also was said that, often times, containers
were not completely empty and contained significant amounts
of chemicals. Finally, the Agency had reports of several
damage cases where the chemical residues left in discarded
containers had caused human health injury. One such incident
involved a child who was hospitalized for organophosphate
-------
poisoning after playing among empty pesticide drums purchased
by the city for use as trash containers.(U.S. House of
Representatives, House Report 94-1491 at 22). On the basis
of this advice, the Agency reasoned that unrinsed contaminated
discarded containers, that had held any of the chemicals
discussed above, could cause injury and pose other substantial
hazards to human health or the environment. Consequently,
it included such containers in the proposed list of hazardous
wastes .
Finally, the Agency recognized that there were occasional
spills during the transportation or storage of chemicals
which resulted in the contamination of soils, waters and
other materials, including debris. Toxic chemicals were no'
more immune to occasional spills during their manufacture,
storage, transportation or use than oils; spills with which
the Agency had considerable experience. Thus, the Agency
concluded that the contaminated spill clean-up residues and
debris from toxic chemical spills, if not properly disposed
of as hazardous wastes, pose substantial hazard to human
health or the environment. Consequently, it included such
residues and debris in the proposed list of hazardous
wastes. In other words, while the Clean Water Act provides
for reporting and clean-up of spilled materials of spills
into the navigable waters, this RCRA provision requires
management of spills of these listed materials as hazardous
waste. Additionally, it provides coverage for in-plant or
other spills not within the scope of the Clean Water Act
regulations.

-------
The Agency's rationale for excluding, from Subtitle C
regulation, hazardous waste generated by retailers and
small quantity generators is discussed in a separate Background
Document. It is to be noted here, however, that the proposed
exclusion was based principally on considerations applicable
to the other hazardous wastes listed in the Proposed Rules.
Chemical products differ from other hazardous wastes in two
respects: generally they are a valuable commodity and therefore
not normally discarded; and, they are discarded in pure,
undiluted form, which increases their risk to human health
and the environment if improperly disposed of. These distinc-
tions led EPA to consider treating these hazardous wastes
separately.
-------
Response to Comments
General
A number of commenters misunderstood the Proposed Rules
and assumed that any waste, including manufacturing process
wastes, containing any of the chemicals listed in Appendices
III, IV, V and XII would be a hazardous waste. This led several
of these commenters to urge that a quantity or concentration
level, below which a waste would not be a hazardous waste, be
established for each chemical listed in the Appendices, Other
commenters urged that, if the Appendices only applied to pure
chemicals and then only applied when they are discarded, these
points should be emphasized. The Agency recognizes that the
language of the Proposed Rules may have been confusing. Con-
sequently, it has substantially re-written the provisions,
currently in §261.33 of the Final Rules, and has added an exten-
sive comment to clarify the points raised by these commenters.
This amplification is further discussed in the following section,
Reconsideration of the Proposed Rules, of this document.
One commenter urged that degree of hazard be incorporated
in the wastes listed in §250.14(a) and the related
Appendices. The Agency's response to comments on the broad
topic of the use of degree of hazard in the listing of hazardous
wastes is discussed in a separate Background Document.
-------
Basis for Listing
A few commenters seemed to suggest that Appendices III,
IV, V and XII should be used to cause wastes containing any
,'
of the listed chemicals to be hazardous wastes. This would
essentially change the list into a "characteristic" with its
attendent responsibilities for the generator. The Agency
did not intend such a result. However, the Agency has revised
its criteria for listing hazardous wastes (see §261.11 of
the Final Rules) to include this concept. The Agency has
developed a list of hazardous constitutents, Appendix VIII,
and will presume that a waste .containing any of those con-
stituents is a hazardous waste unless consideration of other
factors, such as quantity of the waste, concentration of
the toxic agent or mobility of the toxicant, etc., causes
the Agency to conclude that the waste does not pose a substan-
tial hazard to human health or the environment. This criterion
requires the Agency to make a determination to list such
wastes; it is not the responsibility of the regulated community
to designate unlisted wastes as hazardous wastes because
they contain materials on Appendix VIII. Appendix VIII does
in fact contain the toxic substances listed in §261.33(e) of
the final rule. A more detailed discussion of this criterion
is provided in the Background Document covering §261.11 of
the Final Rules.
Several commenters pointed out that the basis for listing
each chemical listed in Appendices III, IV and V was not given;
10
-------
rather the generic basis for listing was given in the waste
classes listed in §250.14(a) where the designation of T, 0 and
M indicated that all the chemicals listed in the Appendices
are hazardous because they possess the toxicity characteristic
and contain toxic organic and carcinogenic, mutagenic and
teratogenic constituents. These commenters noted that certain
of the listed chemicals did not meet all three of these listing
criteria.
The Agency agrees and admits that it should have placed
the specific basis for listing with each chemical in the
Appendices rather than in §250.14(a). In the final rule, EPA
has classified the basi,s for listing the chemical products
subject to regulation. The substances contained in the
original listings have been reviewed to determine whether they
satisfy the listing criteria. A table (Appendix A') accompanying
this background document indicates the disposition of each
substance originally listed. For those that remain on §261.33(e)
the basis for such inclusion is noted. A second table (Appendix
B) indicates the basis for listing of the substances on §261.33(f).
Also noted on these tables are references to the documentary
material supporting the inclusions. These documents include
health effects documents prepared in support of these regula-
tions; materials supporting RPAR actions; background documents
supporting National Interim Primary Drinking Water Standards,
materials of EPA's Cancer Assessment Group; data obtained from
the NIOSH Registry of Toxic Effects, Sax's Dangerous Properties

-------
of Industrial Materials and the Research and Development
Compendium, Part I Materials Classification put out by the
Department of Transportation; and, in the case of chloro-
fluorocarbons, documents supporting regulations under TSCA.
Single List
Two commenters found the three lists of chemicals (Appendices
III> IV and V) confusing and urged that they be combined. The
Agency concurs and has employed only one list for each
category in the Final Rules, (§§261.33(e) and (f)).
Listing of Off-Specification Materials
One commenter urged that a clear distinction be made between
off-specification materials which are reprocessed rather than dis-
carded and that only the latter be regulated. The Final rule has
been clarified to apply only to discarded material.
Listing of ORM-A Substances
Several commenters objected to the listing, in Appendix IV,
of chemicals that are classified by the Department of Transpor-
tation (DOT) as ORM-A materials. These commenters claimed that
ORM-A materials are regulated by DOT because they possess
properties that interefere with transportation safety not because
they are hazardous. An ORM-A material is one that has an
anesthetic, irritating, noxious, toxic or other similar property
which can cause extreme annoyance or discomfort to passengers and
crew in the event of leakage during transportation [49 CFR
173.500(a)(l)]. The Agency concurs with this comment and has
not listed chemicals in the Final Rules simply because they
12
-------
are ORM-A materials. Rather than adopt the proposed list in
toto, EPA has evaluated each substance in accordance with
the criteria for listing. This review has resulted in a
number of chemicals being listed as acutely hazardous in
§261.33(e) and hazardous in §261.33(f) or dropped from the
EPA lists of hazardous wastes because no data was available
to the Agency to support such a listing.
Another commenter objected to Appendix IV, as a whole,
because it listed chemicals that are hazardous in transportation
and not necessarily hazardous at other times. The Agency has
listed a number of chemicals in the Final Rules that DOT
lists as Poison A and Poison B materials. The basis for this
listing, however, is not that they only pose transportation
hazard but, rather, that they are acutely toxic, satisfying the
acutely hazardous criterion, and present a threat to human
health and the environment when discarded.
Listing of Containers
Several commenters were troubled by the inflexibility of the
triple-rinse provision in the proposed listing of containers in
§250.14(a). This provision excluded, as hazardous waste, containers
of the listed chemicals that had been triple-rinsed. This pro-
cedure is an EPA recommended practice for pesticide containers
(40 CFR 165.9) and also a part of several State programs (e.g.,
Washington, Oregon).
Basically, these commenters suggested that there are other
ways to effectively decontaminate containers. One suggested
13
-------
rinsing with one-tenth volume of the container, but did not
specify the type of solution. Another recommended incineration
but gave no specifications. Still another pointed out that
the EPA registered label for the pesticide, Malathion ULV
Concentrate, specifies a rinsing solution and procedure that
does not comport with triple rinsing as defined in the Proposed
Rules. The Agency recognizes that there are a large number
of ways for rinsing or otherwise decontaminating containers.
Many of these methods are unique to the type of chemical
previously contained by the container; e.g., a specific
solvent should be used. As such, the Agency has allowed, in
the final regulations, persons to use alternative methods to
decontaminate containers. The person may, however, be required
to demonstrate that these methods are equivalent to triple
rinsing.
One commenter suggested that the weight of the container
itself be considered in establishing the small quantity generator
exclusion limits proposed in §250.29. EPA does not agree since
the size of the container, i.e., those containers which may be
used by the public for other purposes--e.g., trash cans,
barbecue pits, etc.—is the real concern not the weight of the
container. However, the Agency does consider the weight of
inner liners to be an important factor in setting a de minimis
quantity and, thus, has given consideration to the weight of such
inner liners in establishing the small quantity cut-offs for
small quantity generators.
14
-------
Listing of Spill Residues and Debris
One commenter urged that small amounts of contaminated
spill clean-up residues and debris be excluded from the listing
of these wastes under §250.14(a). The Agency has provided such
an exclusion for aggregate amounts of residue and contaminated
debris less than 100 kilograms (220 pounds). This exclusion
is provided in §261.4(c)(4) and is discussed in the following
section of this document.
Another commenter urged a more precise definition of spill
clean-up debris to avoid including wrecked rail cars and damaged
trucks as hazardous waste. The Agency does not know how to
define debris to avoid the consequences noted by the commenter.
It believes that it can rely on the reasonable implementation
and enforcement of this provision by EPA and State personnel to
avoid absurd results. The difficulty in providing a precise
definition is that occasionally large equipment is severely
contaminated by spilled material. For example, this could
occur in a spill of toxaphene which is an extremely toxic
chemical. The Agency assumes however, that in virtually all
cases, heavy equipment can be decontaminated and need not become
part of contaminated debris. If it cannot be decontaminated
it must be treated as a hazardous waste.
&
Modification of the List of Chemicals
Several commenters urged that procedures be available to
add to or delete from the list of chemicals in Appendices III,
IV, V and XII. The Agency believes that revisions to the list
of chemicals (now in §§261.33(e) and (f)of the Final Rules)
15
-------
should be achieved only through rulemaking. For this purpose
and to enable modifications to other parts of the Subtitle C
regulations, the Agency has provided procedures for petitioning
the Agency to make revisions through rulemaking. These procedures
are established in §260.20 of the Final Rules.
Importantly, deletions from the lists of chemicals in
Appendix VIII and §261.33 are not available through the delisting
procedures established in §260.22. The §260.22 delisting
procedures are designed and intended to apply to individual
generation sites to enable the administrative delisting of
wastes that are fundamentally different from those listed in
§§261.31 and 261.32. The primary difference would be that the
waste did not contain the constituent of concern (or contained
it in such low concentrations that the waste was not hazardous);
or other information could be provided by the generator to demon-
strate significant differences in the persistence, bioaccumulation
potential or mobility potential of the hazardous constitutent;
or significant differences in the quantity or composition of
the wastes. The Agency does not believe that the list of
chemicals in §261.33 present many opportunities for fundamental
differences because they are essentially pure chemicals whose
toxicity, concentration of toxic species, persistence, degra-
dation potential and bioaccumulation potential are fairly well
defined. Spill residues of these materials might vary in con-
centration, of course. This fact led the Agency to establish
larger quantity cutoffs for spill residues of the acutely
16
-------
hazardous materials listed in §261.33(e). Delisting procedures
are not an appropriate manner of handling spill residues and
debris because they generally present unique, rather than
recurring, situations.
With respect to those species listed in §261.33(e), the
chemical substances are acutely toxic or otherwise acutely
hazardous chemicals which pose a substantial hazard in even
very small quantities (see discussion in following section).
Hence, variable quantities is not a fundamentally different
factor for these wastes. As such, the Agency believes that
any difficulties the generator has with those commercial
products listed in §261.33 should and can reasonably be
considered and resolved in the rulemaking process, such that
the delising procedures set out in §260.22 are not amenable
for these types of wastes.
17
-------
RECONSIDERATION OF THE PROPOSED RULES
Criteria for Listing
As discussed in the Background Document covering the criteria
for listing hazardous waste and in response to the overall
criticism by commenters of the proposed criterion for listing
hazardous waste in §250.12(b)(2) of the Proposed Rules, the
Agency has expanded and added considerable specificity to the
criteria for listing hazardous waste in §261.11 of the Final Rules,
One of the final criteria established (§261.11(a)(2), enables the
Agency to list acutely toxic or otherwise acutely hazardous
wastes in Subpart D and designate these wastes as Acute
Hazardous Wastes (having a Hazard Code of H). This criterion
enables the Agency to list a hazardous waste because it has
been found to be fatal to humans in low doses or, in the absence
of data on human toxicity, it has been shown in studies to have
an oral LD50 toxicity (rat) of less than 50 milligrams per
kilogram, an inhalation LC50 toxicity (rat) of less than 2
milligrams per liter, or a dermal LD50 toxicity (rabbit) of
less than 200 milligrams per kilogram or is otherwise capable
of causing or significantly contributing to an increase in
seriously irreversible, or incapacitating reversible, illness.
This criterion was established, in response to commenters
who suggested the need for a specific criterion for listing
the substances, principally to define the basis that the
Agency used in listing in the Proposed Rules the wastes and
18
-------
the related chemicals discussed in this document.* Accordingly,
this change in the final criteria for listing establishes an
explicit basis for the listing of hazardous waste in §261.33(e).
The chemical substances listed in §261.3'3(f) do not
meet the criteria for listing as an acutely hazardous waste but
rather meet the criterion for listing, either because it
satisfies §261.11(a)(1), exhibiting identified characteristics,
«
or §261.11(a)(3), satisfying the toxic criterion. This latter
criterion directs the Administrator to consider a list of
factors to determine whether a waste containing toxic constitu-
ents listed in Appendix VIII is hazardous. Several of these
factors are largely irrelevant in examining chemical substances
in their pure form because the constituent in this case is the
waste.
+
Changes in the Listing of Chemicals
In response to comments, the lists of chemicals proposed
as Appendices III, IV, V and XII have been combined and simplified.
Section 261.33(e) is a listing of commercial chemical products or
manufacturing chemical intermediates which because they pose
a severe acute hazard in small quantities, must be managed
as a hazardous waste in quantities at which most hazardous
waste is exempted. Section 261.33(f) consists of hazardous
substances for which the §261.5(a) and (b) small quantity
exclusion limit is believed to be adequate to protect public
health and the environment.
* However, this criterion also may be used by the Agency to
list hazardous wastes in §§261.31 and 261.32.
19
-------
In addition, the Agency has substantially modified the final
list of chemicals. First, it has listed only commercial chemical
products or manufacturing chemical intermediates, chemicals that
are not normally discarded. The reason for this is that
§261.33 is exclusively designed to regulate these materials in
the event they are discarded or intended to be discarded,
are discarded as off-specification materials, are discarded
as residuals in containers or inner liners of containers or
are spilled. Where the Agency's interest in a chemical is
because it is a hazardous constituent of a solid waste, the
Agency will list the wastes or classes of wastes that typically
or frequently contain such chemicals in §§261.31 and 261.32*.
The principal effect of this approach has been to eliminate,
as a class, the chemicals listed in Appendix V which derived
from a list of toxic chemicals that are typic'ally found in
industrial wastewaters, or as constituents of wastes.
The second major change has been to make the listing of
chemicals under §261.33 of the Final Rules comport to the
listing criterion of §261.11(a)(2) and (a)(3) i.e., those
wastes which present an acute hazard or present a hazard to
human health if improperly managed. Commercial chemical
products or manufacturing chemical intermediates are not
normally discarded. However the Agency is concerned with
controlling those chemicals which when discarded, no matter
how infrequently, could pose a potential hazard. The Agency,
* Hazardous compounds that are a concern because they are
constituents of solid wastes are listed in Appendix VIII and
are used under §261.11(a)(3) to list such wastes as hazardous
wastes.
-------
in this initial promulgation, therefore, is limiting this
list of chemicals to those which could present an hazard
only to human health. Accordingly, under §261.33(e) only
commercial chemical products or manufacturing chemical inter-
mediates that have been found to be fatal to humans in low
doses or, in the absence of data on human toxicity, have been
shown in studies to have an oral LD50 toxicity (rat) of less
than 50 milligrams per kilogram, an inhalation LC50 toxixity
(rat) of less than 2 milligrams per liter, or a dermal LD50
toxicity (rabbit) of less than 200 milligrams per kilogram are
listed in §261.33(e). This change has had the effect of removing
the following groups from the proposed list: the ORM-A materials
listed in Appendix IV of the Proposed Rules, the cancelled and
RPAR review pesticides listed in Appendix III, and the known
or suspected human carcinogens listed in Appendix XII of the
Supplemental Proposed Rules.* Further, under §261.33(f) only
those commercial chemical products or manufacturing chemical
intermediates which may present a potential hazard to human
health, if improperly managed and for which the Agency has
sufficient data to make a determination are listed. Each
chemical was individually reviewed to determine whether it met
the acutely hazardous criterion of §261 .ll(a)(2), the toxic
criterion of §261-11(a)(3), or met the identified characteristics
of hazardous waste.
* This change has not removed the Po.ison A and Poison B materials,
listed in Appendix IV because these are substances that have
an LD50 or LC50 toxicity that meets the criterion for listing.
21
-------
In summary, the combined effect of the two changes
described has been to convert the original list of about 300
chemicals listed in Appendices III, IV, V and XII of the
Proposed Rules to 122 chemicals in §261.33(e) and 239 chemicals
in §261.33(f). Several of the substances in the proposed rules,
for which data was lacking, are currently undergoing review to
determine whether listing on either §261.33(e) or §261.33 (f)
is appropriate. Appendix A to this document provides a
tabular display of these changes.
Rationale for Selecting Acutely Hazardous Criteria
The chemicals on the promulgated list under §261.33(e)
are listed because of one or more of the following criteria:
1. acute oral toxicity
2. acute inhalation toxicity
3. acute dermal-toxicity
4. extreme reactivity (explosivity)
5. capable of causing or significantly contributing to
an increase in serious irreversible, or incapacitating
reversible, illness*
Chemicals listed for acute oral toxicity have been found to
either be fatal to humans upon ingestion of <_ 100 mg/kg or to
have an oral LD50 toxicity to rats of less than 50 milligrams
per kilogram. Chemicals that have these levels of toxicity are
extremely powerful poisons. For example, ingestion of less than
*Thiscriterion was not used in listing the commercial chemical
products or manufacturing chemical intermediates in Section
261.33(e), and therefore will not be further discussed- in this
document.
22
-------
a teaspoonful of these chemicals would be fatal to an adult*.
Additionally, lesser amounts can be expected to cause illness
or even death to children and to more sensitive members of the
population. As can be readily surmised, indiscriminate disposal
of such chemicals could be highly dangerous. Any number of
injury scenarios could result; e.g., accidental contact and
ingestion by children or pets (not unlike situations at Love
Canal); contamination of worker's clothing and resulting
ingestion of small quantities rubbed off the clothing; and
inadvertent contamination of foods or drinking water,
particularly from residuals in containers or from spills.
Because of the acute toxicity of these chemicals, the Agency
has concluded that they very definitely meet the listing
criteria of §261.ll(a)(2 ) and also §261.11(a)(3) .
The acute inhalation toxicity is based on an inhalation
LC50 of less than 2 milligrams per liter. Chemicals having
these levels of toxicity also are extremely effective poisons.
For example, less than 0.2 ounces of such a material are
sufficient to lethally contaminate the air of an average
size (12' by 12' by 8') room. Indiscriminate disposal of
such chemicals could result in any number of dangerous
scenarios; e.g., contamination of the air in refuse collec-
tion bins and trucks posing a danger to workmen; subsurface
migration of such chemicals into the basement of homes, result-
ing in injury to the inhabitants, such as occurred at Love Canal;
*Based on toxicity to rats and humans being the same. The
human is considedred to generally be more sensitive than
the rat due to its higher surface to weight ratio. Using
a surface-area weight relationship for the two species, the
rat is expected to generally be only one-sixth as sensitive
as the adult human.
23
-------
contamination of the air of enclosed structures when salvaged
containers having residues of these chemicals are opened; and
injurious human exposure to these chemicals in certain spill
or spill clean-up situations. Because of the acute toxicity
of these chemicals, the Agency has concluded that they also,
very definitely, meet the listing criteria of §261.ll(a)(2)
and also §261.11(a)(3).
The acute dermal toxicity is based on a skin absorption
LD50 toxicity of less than 200 milligrams per kilogram. Like
those above, chemicals having these levels of toxicity are
extremely poisonous and both indiscriminate and uncontrolled
discriminate disposal can pose injury scenarios similar to
those described above. In fact, the dermal route of exposure
is of major concern since, like inhalation, it can readily
occur, as for example, as a result of contact of children
and pets with the substance and contamination of worker's
clothing. Accordingly, the Agency has concluded that these
chemicals meet the listing criteria of §261.11(a)(2) and also
§261.11(a)(3).
The Agency has used three sources of toxicological
information in determining the LD50 and LC50 toxicities of
chemicals. These are:

*
The extreme reactivity (explosivity) effect is based on
well known properties of the chemical. Three chemicals are
listeti in §261.33(e) for this reason. Each of these is well
known as being explosive under standard temperatures and
pressures. Mild shock is sufficent to cause an explosion and
potentially result in severe injury or death to humans and other
life forms. These three chemicals were not on the proposed list
but would have been hazardous wastes under the proposed
reactivity characteristic.
The chemicals listed in §261.33(e) are all commercial
chemicals and chemical intermediates. The chemicals are listed
in §261.33 by their IUPAC (International Union of Pure and
Applied Chemistry), or in certain instances by their
generic, name. In addition, for the convenience of those using
these regulations, where known, one or more common trade names
are given.
In preparing §261.33(e) the Agency examined the information
available on each of the compounds proposed in Appendices III,
i
IV, V and XII. Those compounds meeting the criteria for
25
-------
inclusion on §261.33(e) are so listed. In addition, the Agency
examined the NIOSH "Registry" to determine if there were any
other compounds which met the criteria. Given these changes
§261.33(e) has been promulgated as "interim final"
rules and the Agency will be accepting comments on the
appropriateness of these listings.
fisting of Containers
Section 261.33(c) of the Final Rules has been expanded to
address the comments on triple rinsing. As now written,
triple rinsing with a solvent capable of removing the commercial
chemical product or manufacturing chemical intermediate is the
standard for Subtitle C regulations by which a container can be
rendered non-hazardous. The limit for containers only applies
to the acutely hazardous materials listed in §261.33(e) because
the residue of these substances in containers may be lethal
in such quantities. For the other hazardous materials listed
in §261.33(f), the containers may not prove hazardous, and EPA
lacks the data to take a general position on this. The
regulation does not specify the type of solvent to be used in
triple rinsing containers. Different solvents may cleanse
chemical product containers with varying results, and it was
impossible for EPA to require the use of a particular solvent
for all containers. In this respect, this Rule is similar to
the general disposal requirements for pesticide containers
promulgated under FIFRA. (See 40 CFR §165.9(a)). In response
to comments, EPA has increased the flexibility of the Rule
by allowing a person to use alternative methods to decontaminate
26
-------
a container, if the person can demonstrate that such methods
achieve equivalent results. For example, government regulations
may authorize a person to incinerate combustible containers
under certain conditions, CF 40 CFR §165.9(a), or a manufacturer
may recommend that such disposal be employed. Several commenters
noted that certain paper containers could not be triple-rinsed.
EPA did not, through these regulations, want to prevent people
. from using these disposal techniques. The Agency is aware that
requiring "equivalent" decontamination procedures without
specifying solvents or procedures provides, at best, a vague
standard. The Agency believes that, in most cases, this rule,
if interpreted sensibly, provides sufficient guidance to both
the regulated community and Agency enforcement personnel. For
most containers, the manufacturer will specify a particular
solvent, or it will be assumed that water is the appropriate
solvent. Unless the knowledge is already extant—e.g., through
manufacturer recommendations—it would appear that most persons
would triple-rinse with water or other dilution liquid rather
•
than conduct tests to determine the equivalency of their procedures.
Accordingly, EPA expects that this alternate procedure will
not be widely used and that triple-rinsing will be the standard
cleansing procedure.
* Public comments on Part 250, Subpart D of the Proposed Rules
raised questions about how the regulations should deal with inner
liners of containers and containers from which the inner liners have
been removed. The resulting reconsideration is reflected in
§261.33(c) as well as in other parts of the regulation.
Basically, inner liners from containers used to hold chemicals
27
-------
listed in §261.33(e) are treated like containers and are
hazardous wastes when discarded unless triple rinsed or
equivalently decontaminated.* On the other hand, containers
from which the inner liner has been removed need not be
considered as a hazardous waste when discarded.
Listing of Spill Residues and Debris
As previously discussed and in response to comments, the
final listing of' spill clean-up residues and debris has been
modified to clarify that only contaminated debris, including
contaminated water and soil, is covered. Also, a provision
has been added to limit this listing to aggregate amounts of
clean-up residues and debris that exceed 100 kilograms (220
pounds). This de minimi s quantity is based on the Agency's
best judgment of an amount that will not overburden the
Subtitle C hazardous waste management system, (including
its implementation and enforcement) and, further, will not
pose a significant risk to human health or the environment.
Based on the Agency experience with the cleanup of spills,
100 kilograms—half a drum—for acutely hazardous wastes is
a very small amount and would only apply to very small or
very limited spills. Given the acute hazardousness of the
chemicals listed in §261.33(e), the Agency does not believe
«
this quantity is too low. In fact, there may be cases where
lesser amounts pose substantial hazard. In such cases, the
"*"Typically, inner liners are not decontaminated and reused; they
are removed from the container and discarded.
28
-------
Agency believes it can rely on the discretion exercised by
the trained personnel that typically respond to spills to
require proper management of these lesser amounts.
29
-------
pe Minimis Quantity Cut-Off for Small Quantities of Acutely
Hazardous Materials ~ ~ ~ ~~" ~
As discussed in a separate Background Document. §261.5 of
the Final Rules excludes (from Subtitle C regulation) hazardous
wastes that are generated, treated or disposed of in quantities
less than 1,000 kilograms (2,200 pounds) in any 30-day period by
individual small quantity generators. The Final Rules further
provide that this 1,000 kilogram exclusion eventually will be
lowered to 100 kilograms (220 pounds) in any 30-day period. The
Agency has concluded that, whereas this exclusion may be
appropriate and justified as a general exclusion for the
variety of hazardous wastes listed in Subpart D, it is not
appropriate for the acutely toxic and hazardous wastes listed
in §261.33(e). These quantity limits do apply to chemical
products listed in §261.33(f). Consequently, §261.5(c) of
the Final Rules provides lesser exclusion limits for the
commercial products listed in §261.33(e).
For commercial chemical products, manufacturing chemical
intermediates and off-specification species listed in §261.33(e),
the dje minimis quantity cut-off is one kilogram (2.2 pounds)
in any calendar month, as provided in §261.5(c). Small
quantity generators who discard more than one kilogram of
these chemicals in any calendar month period must designate
such chemicals as hazardous wastes and these must be managed
as hazardous wastes by the generator and all other persons
(transporters and owners or operators of off-site treatment,
storage or disposal facilities). This quantity, in the
Agency's best judgment, will reduce the risk to human health
30
-------
and the environment, from the discarding of these wastes,
to a very low level (the limit of only one kilogram is a
stringent requirement for persons handling these products in
the course of business). The Agency recognizes that lesser
quantities of these chemicals can be hazardous. As indicated
above, only a few ounces of these chemicals can be lethal or
injurious. At the same time, the Agency recognizes the
implementation and enforcement of small quantity requirements
will be difficult. It will be difficult to inform all potential
generators of the final requirements and it will be virtually
impossible to monitor and police the discarding of small
quantities. The Agency has balanced these two competing
consequences and has concluded that the quantity selected is
a reasonable compromise, particularly when -it applies only
to small quantity generators. These de minimis quantities
do not apply to other generators who must manage all quantities
of §261.33 commercial products ds hazardous wastes.
For containers (except the inner liner of containers that
have been removed) that are not triple rinsed or otherwise decon-
taminated, §261.5(c)(3) provides that the de minimis quantity
threshold is a container size of 20 liters (5.3 gallons).
Persons who discard larger containers must manage them as
hazardous waste. The Agency chose 20 liters because it
believed that there was a larger probability that such
containers, when discarded, might be salvaged for use as
trash cans, barbecue grills, storage containers and other
31
-------
items where human exposure and consequential injury could
occur. It reasoned that there would be a lesser probability
of salvaging of small containers because there is less utility
for such containers.
For inner liners of containers which have been removed and
are discarded; §261.5(c)(4) provides a de minimis quantity cut-off
of 10 kilograms (22 pounds). Jhe same reasoning as used
for the pure chemicals and off-specification materials was
«
used except that adjustment was made for the assumed weight of
the liner. Again, the decision was based on the Agency's best
estimate about the probable risk of injury.
For the clean-up residues and debris from spills, §261.5(c)(5)
provides a 100 kilogram (2,200 pound) de minimis quantity cut-off
(per spill event). The rationale for this choice is discussed
previously in this document.

(a) Any commercial chemical product, or manufacturing
chemical intermediate having the generic name listed in
paragraphs (e) or (f) of this section.
(b) Any off-specification commercial chemical product or
manufacturing chemical intermediate which, if it met•specifica-
tions, would have the generic name listed in paragraphs (e) or
(f) of this section.
(c) Any container or inner 'liner removed from a
container that has been used to hold any commercial chemical
product or manufacturing chemical intermediate having the
generic name listed in paragraph (e) of this Section, unless:
(1) The container or inner liner has been triple
rinsed using a solvent capable of removing the commercial
chemical product or manufacturing chemical intermediate;
(2) The container or inner liner has been cleaned
by another method that has been shown in the scientific
literature, or by tests conducted by the generator, to achieve
