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 wh~ch 

contained the acutely hazardous chemicals. 

1 
PROPOSED RULES 

Synopsis of Proposed Rules 

Appendices III, IV, and V of the Proposed Rules and 

Appendix XII of the Supplemental Proposed Rule listed approximately 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 §2SO.l4(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. 

2 
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 c~emical possessed toxic 

properties: that they either exhibited the proposed Extraction 

Procedure (EP) 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 c~ntain 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 

3 
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 

~aterials without being subject to the Subtitle C regulations. 

Consequently, these chemicals and associated materials effectively 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. 

4 
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" 

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 offspecification materials were toxic and, even though discarded 

only occasionally (and usually in small amo~nts,) 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 offspecification 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 

6 
hazards to human health or the environment. Consequently, 

it includei 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 ~f 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. 

7 
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 

la~guage of the Proposed Rules may have been confusing. Consequently, it has substantially re-written the provisions, 

currently in §261.3~ of the Final Rules, and has added an extensive 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 §2SO.l4(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 constituents 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.ubstantial hazard to human health or the environment. This criterion 

requires the Agency to make a determination to list such 

wastes; it is not ~he 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; 

9 
rather the generic basis for listing ~as given in the waste 

classes listed in §2SO.l4(a) ~here the designation of T, o 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 §2SO.l4(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 ~hether 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(£). 

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 regulations 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 

10 
of Industrial Materials and the Research and Development 

Compendium, Part I, Materials Classification document published 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 (Appendic~s 

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 discarded 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 Transportation (DOT) as ORM-A materials. These commenters claimed that 

ORM-A materials are regulated by DOT because they possess 

r 

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)(l)J. 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 

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 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 procedure 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 ~ith one-tenth volume of the container, but did not 

specify the ~:?e of solution. Another recommended incineration 

but gave no specification~. Still another pointed out that 

the EPA registered label for the pesticide, Malathion ULV 

Concentrate, S?ecifies 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 wethods 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, ho~ever, 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. 

13 
Listing of Spill Residues and Debris 

One comoenter 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 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) 

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 de1isting 

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 const~tuent of concern or contained 

it in such low concentrations that the waste was not hazardous. 

Other information could be provided by the generator to demonstrate 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 opportunities for fundamental differences because as commercial 

procucts 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 concentration, 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 h~ndling 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 commenters on the proposed criterion for listing 

hazardous waste in §2SO.l2(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 (§26l.ll(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 LDSO toxicity (rat) of less than SO milligrams per 

kilogram, an inhalation LCSO 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(£) do not 

meet the criteria for listing as an acutely hazardous was~e but 

rather meet the criterion for listing, either because theY 

satisfy §26l.ll(a)(l), exhibiting identified characteristics, 

or §26l.ll(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 §26l.ll(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 

induRtrial 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 §26l.ll(a)(2) and (a)(3) i.e., those 

wastes which present an acute hazard or present a hazard to 

human health if iQproperly 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 po~e a potential hazard. The Agency, 

has thus restricted the present list of chemicals to only 

those which could present an hazard oniy to human health. 

Accordingly, under §261.33(e) only commerci·al chemical products 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 LDSO toxicity (rat) of less than 50 milligrams 

per kilogram, an inhalation LCSO toxicity (rat) of less than 

2 milligrams per liter, or a dermal LD50 toxicity (rabbit) 

of less than 200 milligrams per kilogram are li~ted 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 Pbison B materials 

listed in Appendix IV because these are substances that have 

an LDSO or LCSO toxicity that meets the criterion for listina. 0 

20 
thnse coooercial 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 §26l.ll(a)(2), the toxic 

criterion of §26l.ll(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) 

s. capable of causing or significantly contributing to 

an increase in serious irreversible, or incapacitating 

reversibl~, 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 LDSO 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 §26l.ll(a)(2) and also §26l.ll(a)(3). 

The acute inhalation toxicity is based on an inhalation 

LCSO 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 mate~al 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 collection bins and trucks posing a danger to workmen; subsurface 

migration of such chemicals into the basement of ho~es, resulting in injury to the inhabitants, such as occurred at Love Canal; 

contamination of the air of enclosed structures ~hen 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 §26l.ll(a)(2) 

and also §26l.ll(a)(3). 

The acute dermal toxicity is based on a skin absorption 

LDSO toxicity of less than 206 milligraos 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 si~ilar 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 

chemicals meet the listing criteria of 

§261.1l(a)(3). 

23 

conclu~d that these 

§261.1~a)(2) and also 
The Agency has us~d three sources of toxicological 

informatio1 in determining the LD50 and LCSO toxicities of 

chemicals. These are: 

~esearch and Development Compendium, Part :, Materials 

Classification, Volume II Toxic & Corrosive Materials, 

1976, u.s. Department of Transportation, Office of Hazarjous 

Materials Operations, Materials Transportation Bureau, 

Washington, DC 20590.

Materials, Fourth Edition, 1975, Van Nostrand Reinhold,

Registry of Toxic Effects of Chemical Subs:a~ces, 

Publication Number 73-104-E, Septe~ber 1977, Na:ional 

Institute of Occupational Safety and Health, Ci~cinnati, 

OR 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 

tetranitromethane --are listed in §261.33(e) o~this basis. 

These compounds are extremely reactive; they explode under 

standard temperatures and pressures. A mild shock is suffi~ient 

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 com~ercial 

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 ~ay cle~nse 

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 

~*~N~o--t_e_:--~C-e_r_t-ain portions of the discussion in this ~ ction have 

been supreceded by clarifying amendments deliing 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 qu·:stions 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 Age~cy 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 
D~ Minimis Quantity Cut-Off for Small Q~antities 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. !he Final Rules further 

provide that this 1,000 kilogram exclusion eventually will be 

lowered to 100 kilograms (220 pounds) i~ 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, ~anufacturing chemical 

intermediates and off-specification species listed in §261.33(e), 

the de minimis quantity cut-off is one ~ilogram (2.2 pounds) 

in any calendar month, as provided in §261.5(c). Small 

quantity generators who discard m~re 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 jud~ment, 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 

implementatio~ 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 linP.r of containers that 

have been removed) that are not triple rinsed or otherwise decontaminated, §261.5(c)(3) provides that the de minimis quantity I 

threshold is a container size of 20 liters (5.3 gallons). 

Persons who discard larg~r 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 
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). 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) ~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 implementin~ Sect1'on 3001 ~ RCRA - . o... ) 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 offspecification va~iants 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, 

§261.33 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 

rr' ...... (§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 themselves. Comnents 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 tradename 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. 

the remaining responses. 

As stated, the preamble contains 

82 
I. Finalization~emical Product Names in §261.33(e) and (f) 

A. The changes made in response to comments on specific Hstings are described summar lly belo'"· Hore detailed 

explanations are contained in the revised Background Document.

*/The commenter, in urging deletion of alpha-chlorotoluene, referred to the Agency's statement in 45 Fed. Reg. 

- 47833 (J1tly 16, 1980) that chlorotoluene did not warrant Inclusion in Appendix VIII to Part 261. 

Chlorotoluene and alpha-chlorotoluene are different compounds, of course. Alpha-chlorotoluene, also 

known as benzyl chloride, not only is ac1ttely toxic, but has shown evidence of carcinogenicity (see Listing 

Background Document on Benzyl Chloride production).

~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 specifications, 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 ?r 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 

of a container, the inner liner that 

102 
manufactur7ng 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 manufacturing 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 comoercial chemical products or manufacturing chemical intermediates, referred to in paragraphs (a) through (d) of this section, are 

:dentified 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.]

E • Discarded Commercial Chemical Products, Off-Specification 

Species, Containers, and Spill Residues Thereof (§261.33) 

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 (1-(p-chlorobenzoyl)-5-methoxy-2-methylindole-3-acetic 

acid) with a very similar compound appearing on the Agency's 

Carci~ogen Assessment Group's list of substances exhibiting 

substantial evidence of carcinogenicity. Since indomethacin 

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(£). 

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 

of spills of commercial products and manufacturing 

chemical intermediates). These provisions do in fact apply 

131 
~hen off-specification materials are involved, but the 

regulatory language is so~e~hat 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). 

Ho~ever, to avoid any confusion, the Agency has decided to 

amend §§261.33 (c) and (d) to refer explicitly to offspecification materials. A conforming amendment also has 

been added to §261.5(e)(2) to make clear that the 100 kg cutoff linit for cleanup residues of spills of §261.33(e) 

materials applies to spills of acutely hazardous offspecification materials.l 

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. 0244 is incorrect; the number should read 0224. This 

typographical error is corrected by this notice. 

Finally, a number of mistakes and typographical errors 

~ere noted in §§261.33(e) and (f) after revie~ing this section 

(45 FR 78541 - 78544). These are discussed in the follo~ing 

table: 

£A 7evised version of §261.33(c), ~hich clarifies the status 

of residues of §261.33(c) materials in containers, is slated 

to beco~e effective on May 25, 1981. See 45 FR at 78529 

(~ovember 25, 1980). The Agency will conform the text of 

that a~endment ~ith the regulatory languaeP. adopted today 

at the time of final promulgation.

136 

REASON 

compound should read: 

2,4-D, salts and esters. 

This compound was ommlted 

mistakenly from §261.33(£). 

Methoxychlor is an EP Toxicity 

constituent and is also one of 

the materials regulated by a 

National Interim Primary 

Drinki~g Water Standard; its 

toxicity 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 inculcled 

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 \-later 

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 ndeqwtt:e notlc.e 

for inclusion of this compound 

in §261.33, and is taking thls 

opportunity to add it to 

§261.33(£). 
3 • The authority citation for Part 261 reads as follo~s: 

AUTHORITY: Sees. 1006, 2002(a), 3001, and 3002

the Resource Conservation and Recovery Act of 

of 1976, as amended (42 u.s.c. 6905, 6912(a), 

6921 and 6922). 

~. In FR Doc. 80-36683, appearing at page 78531 in the
