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 are 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 selecting these chemicals EPA relied heavily on the work
done by other offices in the Agency and by other agencies. The
Agency believed that each listed chemical possessed toxic
properties: that they either exhibited the proposed Extraction
Procedure (SP) toxicity characteristic or that they were
either toxic, explosive, ignitable, reactive, mutagenic,
carcinogenic or teratogenic substances. The Agency had
not, however, conducted a laboratory evaluation of each
substance with reference to either the characteristics or
the criteria for listing (§261.11).
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 discarded occasionally.
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"
i
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, commercial products 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.
The Agency therefore concluded that pesticides 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
5
-------
toxic pollutants being regulated under §307(a) of 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 the
solid waste generated consisted of nominally "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, oftentimes, 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 include*1" 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.
-------
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.
8
-------
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 s.ubstan-
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 listin-g
each chemical listed in Appendices III, IV and V was not given;
-------
rather the generic basis for listing was given in the waste
classes listed in §250.14(a) where the designation of T, 0 end
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 basis 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

Compendium, Part I, Materials Classification document pub-
lished by the Department of Transportation. In the case of
chlorofluorocarbons, documents supporting regulations under
the Toxic Substances Control Act also are included.
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, namely §§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
Y
properties that interefere with transportation safety not because
they are hazardous when disposed. 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)(1)]. The Agency concurs with this comment and has
11
-------
not listed chemicals in the Final Rules simply because they
are ORM-A materials. Rather than adopt the proposed list in
to t o, 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 hazards during
transportation but rather that they are acutely toxic, satisfying
the acutely hazardous criterion, and so 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
12
-------
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
x
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 aethods are unique to the type of chemical
previously contained by the container; e.g., a specific
solvent should be used. As such, in the final regulations,
the Agency has allowed 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 comiaenter suggested that the weight of the container
itself be considered in establishing the small quantity generator
exclusion limits proposed in §250.29. SPA 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.
13
-------
Listing of Spill Residues and Debris
One coranenter 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 of less than 100 kilograms (220 pounds) for
aggregate amounts of residue and contaminated debris resulting
from the cleanup of a spill of any commercial cleaning product
or manufacturing chemical intermediate having the generic
name listed in §261.33(e). This exclusion is provided in
§261.5(c)(5) 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.
14
-------
Modification of the List of Chemicals
Several comraenters 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)
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.
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 chemicals
and commercial products covered by §261.33 present many oppor-
tunities for fundamental differences because as commercial
products their toxicity, concentration of toxic species,
15
-------
persistence, degradation 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
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.
16
-------
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 comtnenters on 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 (§ 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 change in the final criteria for listing establishes an
explicit basis for the listing of hazardous waste in §261.33(e).*
However, this criterion also may be used by the Agency to
list hazardous wastes in §§261.31 and 261.32.
17
-------
The chemical substances listed in §261.33(f) do not
meet the criteria for listing as an acutely hazardous waste but
rather meet the criterion for listing, either because they
satisfy §261 .11(a)(1), exhibiting identified characteristics,
or §261.11(a)(3), satisfying the criteria for listing as
toxic. This latter criterion directs the Administrator to
consider a list of factors to determine whether a waste
containing toxic constituents listed in Appendix VIII is
hazardous. The most important of these factors, and in the
case of discarded or spilled commercial products, the decisive
factor, is the nature of toxicity presented by the constituent
of concern. This is because there is substantial indentity
between the constituent of concern and the discarded product.
In fact, in most cases the waste (i.e., the discarded product)
essentially is the constituent of concern. Thus being the
case, the remaining factors in §261 .11(a)(3) are largely
irrelevant to a listing determination.
In listing materials in §261.33(f), therefore, the Agency
either will indicate that the listed material exhibits a
characteristic, or will indicate the nature of toxicity
posed by the constituent of concern.
18
-------
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 human
health and the environment.
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 typically found in
industrial wastewaters, or as constituents of wastes.
19
-------
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,
has thus restricted the present list of chemicals to only
those which could present an hazard only to human health.
Accordingly, under §261.33(e) only commerci'al chemical pro-
ducts or manufacturing chemical intermediates 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 toxicity (rat) of less than
2 milligrams per liter, or a dermal LD50 toxicity (rabbit)
of less than 200 milligrams per kilogram are li-sted 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
*This change has not removed the Poison 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.
20
-------
tho.se 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 §261.11(a)(2), the toxic
criterion of §261.11(a)(3), or met the identified characteristics
of hazardous waste.
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
21
-------
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
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 §261.11(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
*Based on toxicity to rats and humans being the same. The
human is considered generally to 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.
22
-------
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;
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 § 261.11(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 siailar 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.Irfa)(2) and also
§261.11(a)(3) .
23
-------
The Agency has used three sources of toxicological
information in determining the LD50 and LC50 toxicities of
chemicals. These are:
Research and Development Compendium, Part I, Materials
Classification, Volume II Toxic & Corrosive Materials,
1976, U.S. Department of Transportation, Office of Hazardous
Materials Operations, Materials Transportation Bureau,
Washington, DC 20590.
Sax, N. Irving, Dangerous Properties of Industrial
Materials, Fourth Edition, 1975, Van Nostrand Reinhold,
New York, NY 10001.
Registry of Toxic Effects of Chemical Substances,
Publication Number 7S-104-B, September 1977, National
Institute of Occupational Safety and Health, Cincinnati,
OH 45226.
In using these references, the Agency has only used citations
based on observed toxic effects in humans, rats, and rabbits.
The Agency has thus far been sparing in exercising its
authority to list substances "capable of causing or significantly
contributing to an increase in serious irreverisble, or
incapacitating reversible illness." In the final rule, three
compounds -- ammonium picrate, 2,4,6-trinitrophenol, and
P\
tetranitromethane — are listed in §261.33(e) oh this basis.
\J
These compounds are extremely reactive; they explode under
standard temperatures and pressures. A mild shock is sufficient
24
-------
to cause an explosion. The Agency therefore believes that
these compounds are properly includible as acutely toxic
wastes, and should, when discarded be subject to the lower
exclusion limit.
Listing 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 x*hich 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 nay 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
*Note: Certain portions of the discussion in this section have
been supreceded by clarifying amendments de&iing with
containers, container liners, and the contained residue.
See 45 FR 78254 (November 25, 1980), adopting a new
§261.7 and a. revised §261.33(c).
25
-------
promulgated under FIFRA. (See 40 CFR §165.9(a)). In response
to comments, EPA has increased the flexibility jf the Rule
by allowing a person to use alternative methods to decontaminate
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.
26
-------
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
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 minimis 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,
* Typically, inner liners are not decontaminated and reused;
they are removed from the container and discarded.
27
-------
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
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.
28
-------
Dg 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 de 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
29
-------
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 as 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
30
-------
iteas 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 d_e minimis quantity cut-off
of 10 kilograms (22 pounds). The 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.

Response To Comments on Interim Final Regulations
On May 19, 1980, as part of Its final and interim final
regulations implementing Section 3001 of RCRA, the Agency
promulgated as §261.33 the regulations discussed in the first
part of this background document. This regulation consists of
a list of 361 commercial chemical products or manufacturing
chemical intermediates which are hazardous wastes if they
are discarded or intended to be discarded (see 45 FR 33124-
33127). Section 261.33 also lists as hazardous wastes off-
specification va-riants and the residues and debris from the
clean-up of spills of these 361 chemicals, if discarded or
intended to be discarded (§261.33(b) and (d)). Finally,
§251.33 lists as hazardous wastes the containers and inner
liners of containers that have held 122 of these chemicals
(those listed in paragraph (e)), if they are discarded or
intended to be discarded, unless they have been triple rinsed
with an appropriate solvent or have been decontaminated in
an equivalent manner. (§261. 33(c).) The regulation also
covers materials not specifically listed by name, so long
as they "have the generic name listed in paragraphs (e) or
*P " (§261.33(a), (b), (c), and (d).)
The Agency received a large number of comments on this
regulation. The comments for the most part challenged the
Agency's decision to list particular substances as hazardous
wastes. Some questions also were raised regarding the scope
of the regulation, particularly with respect to trade products
81
-------
containing a listed chemical but not specifically listed them-
selves. Comments also were submitted concerning the difficulty
of determining the chemical constituents of unlisted trade
name products. Finally, many questions have been received
regarding the interpretation of §261.33.
The Agency responded to these comments in the preamble
to the final regulations (45 FR 78532, November 25, 1980).
That preamble set forth the Agency's disposition of all
listings of particular substances, and the basis for the
Agency's decision. The Agency also clarified the scope of
coverage of trade products, and provided guidance as to how
to determine whether a given tradenaiae product is regulated
under §261.33. Certain interpretative questions raised
regarding §261.33 also were addressed.
The Agency has little to add to these responses. We
have expanded slightly our responses to the comments on
listings of specific chemicals, and these comments are included
in this background document. As stated, the preamble contains
the remaining responses.

Added (R)
designation.
2-Butanone peroxide and methyl ethyl
ketone peroxide, synonyms for the
same compound, were mistakenly Inclu-
ded in both the §261.33(e) and (f)
lists. This compound does not meet
the clrteria for listing as an
acutely hazardous waste. However,
the compound's oral (rat) LD50 of
484 ing/kg qualifies it for continued
inclusion in §261.33(0- Moreover,
2-butanone peroxide presents a sub-
stantial hazard if improperly managed
due to its severe reactivity. Being
a strong oxldlzer an explosion could
occur if the materials such as would
be found in trash for example.

After reviewing In more detail tlie

eluded that pentachloroplienol does not
meet the criteria for an acutely hazard-
ous waste (see the response to common in
aectlon of the November 1980 Wood
Preserving Waste Listing Hackground
Document for more Information).
However, Its toxic U.y Is well recognized
and the waste will remain listed under
§261.33(0 as U242.
The T.D50 value cited In support of the

New diita Indicates that the compound Is

oven .If the waste Is Improperly managed .
This decision Is further supported by the
Pood & Drug Administration's approval of
this compound as a direct food additive.
According to the N10SI1 "Registry of
ToKlc Effects of Chemical Substances",
thluram Is a synonym for bls(dimethylthlo-
carbamoyl) dlsulfldc. Comments were
received which Indicated that other
compounds were also known as "thlurams".
We have accordingly changed the listing
"thluram" to clarify that the Intended
compound Is "bls(dlmethylthlocarbamoyl)

Secondly, the human (oral) l.ni.o data

After reevaluatlnp, the availahle

to include both the parent compound as

cial use Includes (and Is known to
Include) both forms. In light of thJs
common usage, we do not believe that
any notice and comment Issue;; are
present.
The arguments that saccharin Js not
carcinogenic were not deemed persuasive
enough by the Agency to warrant deletion
from §261.33 list. That saccharin poses
a significant carcinogenic hazard is
amply demonstrated by the warnings that
are required by the Food & Drug Admin-

The Agency had mistakenly listed this
compound. It does not exist.. The
correct compound is "Phosphorothiolc acM,
0,0-dimethyl 0-[p-((diraethylamino)-sul-
fonyl)phenyl] ester."
The (R) designation was Inadvertantly
omitted. While tetranitroinethane Is
toxic (as was pointed out earlier,
it Is acutely hazardous because of
tetran!tromethnne1s explosive properties.
This compound does not pose a sufficient
hazard for listing because of toxlctty.
However, acetaldehyde's flash point of
-37.B°C classes It: as a hazardous wasti?
by reason of lj»n Itabll i ty .
The reactivity designation was mistakenly
omitted from the listing, although the
May 19th promulgation cited reactivity
as a reason for listing.
In addition to aniline's Ignltable
properties, It Is c-ilso toxic with an
oral (rat) LD50 of 440 mg/kg (3).
As well as being toxic, this compound
Is highly flammable (10-12°C). (3).
In addition to carbonyl flourlde's
toxic properties, as was Indicated

it also poses a hazard due to Its
reactivity.

In addition, the acute toxiclty of phenol results in central

P •i-nol .1 tonicity rating of 'High' In Sax (1). This standard
reference Indi.-alea that "death or permanent injury may occur
due to exposure at normal use ...". Therefore, the Agency
will continue to include phenol under §26.1.33(f).
While the commentcr believes that compounds, such as this one,
having an oral (rat) LD50 of 570 mg/kg are not toxic, the Agenc
disagrees. Other standard sources support the Agency's
viewpoint. For example, "Clinical Toxicology of Commercial Pro.•<• I ti|
toxic effects of te.traclilorobenzene are Its aquatic toxiclty
(14.5 ug/1) and bloconcentration factor (1800X). Since the
commenter did not present any specific evidence or reasons for
the Agency not to list tetrachlorobenzene as a hazardous waste,
It will remain listed under §261.33(f).

No da I.a was presented by the common Car to justify the contention
that waste 1 ,1, l-l r ichl oroethane does not pose a health ha/.ard
and should not be listed. As the bioassays described in the May
19th Appendix A Health and Environmental Effects Profile Indlcat
Increased tumor production was noted In animals treated with
I,1,t-LrIchIoroethane. In addition, In vitro transformation of
rat embryo cells and subsequent firbosarcoma production by these
cells' when Injected In vivo, also indicates that 1,I,l-trIchloro
ethane has carcinogenic potential. It should also be noted thai
the Aj'.ency recently determined that 1,1, l-Trtchl oroethane should
continue to be listed as a toxic pollutant under 5T1/(a) of
the Clean Water Act,
One eoiiimenter questioned the presence of these constituents
on the !>?f>l.'n list when the waste constituents are amonp, the
parameters measured by the characteristic of Extraction Pro-

academic since discarded commercial chemical product.s rou.s I «?t-

Final Regulations
§261.33 Discarded Commercial Chemical Products,
Off-Specification Species, Containers, and
Spill Residues Thereof
The following materials or items are hazardous wastes if
and when they are discarded or intended to be discarded:
(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
equivalent removal; or
n
(3) In the case of a container, the inner liner that
vj
prevented contact of the commercial chemical product or
102
-------
manufacturing chemical intermediate with the container, has
been removed.
(d) Any residue or contaminated soil, water or other debris
resulting from the cleanup of a spill, into or on any land or
water, of any commercial chemical product or manufacturing
chemical intermediate having the generic name listed in
paragraphs (e) or (f) of this Section.
[Comment: The phrase "commercial chemical product
or manufacturing chemical intermediate having the
generic name listed in..." refers to a chemical
substance which is manufactured or formulated
for commercial or manufacturing use. It does
not refer to a material, such as a manufacturing
process waste, that contains any of the substances
listed in paragraphs (e) or (f). Where a manufac-
turing process waste is deemed to be a hazardous
waste because it contains a substance listed in
paragraphs (e) or (f), such waste will be listed
in either §§261.31 or 261.32 or will be identified
!
as a hazardous waste by the characteristics set
forth in Subpart C of this Part.]
103
-------
(e) The commercial chemical products or manufacturing chemical inter-
mediates, referred to in paragraphs (a) through (d) of this section, are
identified as acute hazardous wastes (H) and are subject to the small
quantity exclusion defined in §261.5(e). [Comment: For the convenience of
the regulated community the primary hazardous properties of these materials
have been indicated by the letters T (Toxicity), and R (Reactivity). Absence
of a letter indicates that the compound only is listed for acute toxicity.]

§261.33 updated April 1981. FR dt
E. Discarded Commercial Chemical Products, Off-Specification
Species, Containers, and Spill Residues Thereof (§261.537
1. Deletion of Indomethacin
The Agency, at 45 FR 76533, indicated that the drug
indomethacin would continue to be regulated as hazardous
waste U245 when discarded. This action was a mistake, and
resulted from the confusion of indomethacin's generic chemical
name (l-(p-chlorobenzoyl)-5-methoxy-2-niethylindole-3-acetic
acid) with a very similar compound appearing on the Agency's
Carcinogen Assessment Group's list of substances exhibiting
substantial evidence of carcinogenicity. Since indoraethacin
does not otherwise appear to pose a substantial threat to
human health and the environment if managed improperly, the
Agency is deleting it from §261.33(f).
2. Regulation of Containers Which Formerly Held Acutely Hazardous
Off-Specification Materials, and Regulation of Cleanup Residues
of Spilled Off-Specification Materials
Questions have been raised as to whether §§261.33(c) and
(d) of the regulations apply to containers which formerly
held acutely hazardous off-specification materials (as well
as to containers which formerly held commercial products and
manufacturing chemical intermediates) and to cleanup residues
of spilled off-specification materials (as well as to cleanup
K7l?ues of spills of commercial products and manufacturing
chemical intermediates). These provisions do in fact apply
131
-------
when off-spec ification materials are involved, but the
regulatory language is somewhat confusing. §§261.33(c) and
(d) apply to materials listed in §§261.33(e) and (f). Both
of these provisions cover by reference, among other materials,
the off-specification materials referred to in §261.33(b).
However, to avoid any confusion, the Agency has decided to
amend §§261.33 (c) and (d) to refer explicitly to off-
specification materials. A conforming amendment also has
been added to §26l.5(e)(2) to make clear that the 100 kg cut-
off limit for cleanup residues of spills of §261.33(e)
materials applies to spills of acutely hazardous off-
specification materials.^-
3. Correction of Non-Substantive Errors
In the November 25, 1980 Federal Register, the wrong
EPA Hazardous Waste Number was used to reference a specific
chemical in the preamble to this section of the November 25,
1980 Federal Register (45 FR 78535). Specifically, toxaphene
listed in the table at 45 FR 78535 as EPA Hazardous Waste
No. U244 is incorrect; the number should read U224. This
typographical error is corrected by this notice.
Finally, a number of mistakes and typographical errors
were noted in §§26l.33(e) and (f) after reviewing this section
(45 FR 78541 - 78544). These are discussed in the following
table:
^- A -revised version of §261.33(c), which clarifies the status
of residues of §261.33(c) materials in containers, is slated
to become effective on May 25, 1981. See 45 FR at 78529
(November 25, 1980). The Agency will conform the text of
that amendment with the regulatory language adopted today
at the time of final promulgation.

This compound was ommited
mistakenly from §261.33(f).
Methoxychlor is an EP Toxicity
constituent and is also one of
the materials regulated by a
National Interim Primary
Drinking Water Standard; its
toxlclty therefore is well
recognized. The background
document for §261.33 indicated
that all compounds for which
a National Interim Primary
Drinking Standard has been
established are to be inculded
under §261.33 (Background
Document for §261.33, April 30,
1980, at pp. 19, 70), and all
of the other pesticides covered
by a Primary Drinking Water
Standard are included under
§261.33. In fact, comments
were received questioning the
(unintended) omission of
methoxychlor. The Agency
therefore believes that It
has provided adequate notice
for Inclusion of this compound
in §261.33, and is taking this
opportunity to add It to
§261.33(f).
