                       INTRODUCTION







     This background document  explains  the  basis  for  regulations




concerning discarded commercial  products, which are described




and listed in §261.33 and  for  which  exclusion  levels  are




established in §261.5.  Commercial chemical  products  or




manufacturing chemical intermediates  are divided  into  two




categories:  those which are acutely  hazardous and subject  to




stringent exclusion levels; and  those which  are hazardous




and which axe regulated in  the same manner  as  other hazardous




wastes.  These regulations  concern commercial  chemical products,




and associated off-specification chemical products, spill




cleanup residues and debris.   For acutely hazardous chemicals,




the regulations also cover  containers and inner liners which




contained the acutely hazardous  chemicals.

-------
                       PROPOSED RULES







Synopsis of Proposed Rules




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




Appendix XII of the Supplemental  Proposed  Rule  listed approx-




imately 300 toxic chemicals.  Appendix III listed  24  pesticides




which either had been cancelled for  some or all uses  under  the




Federal Insecticide, Fungicide and Rodenticide  Act (FIFRA)




or were undergoing RPAR  (rebuttable  presumption against




registration) under FIFRA.  Appendix IV  listed  157 chemicals




that were listed as Poison A, Poison B or  ORM-A materials  in




the Department of Transportation  regulations under 49 CFR




Parts 172 and 173.  Appendix V listed  the  remainder of the  129




toxic priority pollutants (not already included on Appendices




III or IV) for which effluent guidelines limitations  were  being




developed under the Clean Water Act.  Appendix  XII listed  33




chemicals that had been  found to  be  human  carcinogens or




potential human carcinogens by the International Agency  for




Research on Cancer.




     By reference to the appendices  these  hazardous chemicals,




if discarded, were listed as hazardous wastes in §250.14(a)




of the Proposed Rules.   In addition, §250.14(a) also  provided




that off-specification species of  these  toxic chemicals, if




discarded; the emptied containers  from these chemicals,  if




not triple rinsed; and the clean-up  residues and debris  from




spills of these chemicals were hazardous wastes.

-------
     In adopting these chemicals  EPA  relied  heavily  on  the  work




done by other offices in the Agency,  or  by other,  agencies.   The




Agency believed that each listed  chemical possessed  toxic




properties:  that they either  exhibited  the  proposed  toxicity




characteristic or that they were  toxic organic  or mutagenic,




carcinogenic or teratogenic substances.  The Agency  had




not, however, evaluated each substance with  reference to




either the characteristic of hazardous waste or criteria




for listing .




     These chemicals were proposed  to be hazardous wastes if




(1) they, themselves, were discarded, (2) off-specification




species of these chemicals were discarded, (3)  containers




which formerly contained these chemicals were discarded or




(4) clean-up residues and debris  from spills of these chemicals




were discarded.  Importantly,  these chemicals were not  listed




to be used to cause  solid wastes  derived from manufacturing




processes (and which might only contain  very low  concentrations




of these chemicals)  to be listed  as hazardous wastes'.   As is




noted later in this  document,  this  point was misunderstood




by many commenters.




     Section 250.29(a) of the  Proposed Rules provided that  any




retailer or any person who produced and  disposed  of  no  more




than 100 kilograms of hazardous waste in any one  month  would




not be subject to the full Subtitle C regulation  if  the waste




was disposed of in a Subtitle  D facility.  The  effects  of this




exemption were that  (1) any retailer  could discard any  and  all




quantities of these  chemicals  or  the  associated materials

-------
described above without being  subject  to  regulation  and  (2)

any small quantity generator could discard as much as  100

kilograms per month* of these  chemicals or the  associated

materials without being subject  to the Subtitle C regulations.

Consequently, these chemicals  and associated materials effec-

tively were hazardous wastes only if generated  by non-retail

and large-quantity (greater  than 100 kilograms  per month)

generators .
 * Provided he discarded no  other  hazardous wastes.   The
   exemption, as proposed, covered  total  quantity  of  hazardous
   wastes.  Hence, only 100  kilogram  of the 295  chemicals
   and other hazardous wastes,  in  aggregate,  in  any one
   month, were excluded.  The  final exlcusions also relate  to
   total quantities of hazardous waste.

-------
Rationale for Proposed  Rules




     In the development of  the Proposed Rules, a number of




persons, pointed  out  that  an  important part of the hazardous




waste generated  throughout  the country were commercial chemicals




that normally are not discarded but,  for a variety of reasons,




are occasionally  discarded.




     Examples given were reduction of inventory, changes in




product line, cancellation  of pesticides, no further use for




remaining stocks  and residuals from batch-process manufacturing




or formulating  operations.   In particular operators of solid




waste management  facilities indicated that some "wastes"




which they  receive are  discarded pure chemicals as opposed




to typical  wastes from  'manufacturing  or other activities.




These same  persons also indicated that off-specification




chemicals are  sometimes discarded.  The Agency recognized




that  some of  these chemicals  and off-specification materials




were  toxic  and,  even though discarded only occasionally (and




usually in  small  amounts,)  could pose a substantial hazard




to human health or the  environment.

-------
     In concert with  this  advice,  the  Agency concluded that pesti-




cides that had been cancelled  or  were  being  reviewed  for possible




cancellation action (Appendix  III  of  the  Proposed  Rules) and




Poison A, Poison B and ORM-A materials that  are  regulated by




the Department of Transportation  because  of  their  threat to




safety (Appendix IV)  constituted  chemicals that  were  toxic




and, if discarded, could pose  substantial hazard to  human




health or the environment.  It  further concluded that  the




toxic pollutants being regulated  under §307(a) under  the




Clean Water Act (Appendix  V, unless  already  listed in  Appendix




III or IV,) and known or suspected human  carcinogens  (Appendix




XII) were hazardous materials  that posed  significant  risk to




human health or the environment,  if  discarded.   Consequently,




these chemicals were  listed in  the Proposed  Rules  and  were




established to be hazardous wastes if  they or their  off-




specification species were discarded.




     The Agency also  learned that  a  significant  part  of  solid




wastes was empty containers, including containers  that had contained




toxic chemicals.  These  empty  containers  typically contain




chemical residues because  they  had not been  rinsed or  otherwise




decontaminated.  It also was said  that, often times,  containers




were not completely empty  and  contained significant  amounts




of chemicals.  Finally,  the Agency had reports of  several




damage cases where the chemical residues  left in discarded




containers had caused human health injury.   One  such  incident




involved a child who  was hospitalized  for organophosphate

-------
poisoning after playing  among  empty  pesticide  drums  purchased




by the city for use as trash containers.(U.S.  House  of




Representatives, House Report  94-1491  at  22).   On  the basis




of this advice, the Agency  reasoned  that  unrinsed  contaminated




discarded containers, that  had held  any  of  the chemicals




discussed above, could cause injury  and  pose other substantial




hazards to human health  or  the environment.  Consequently,




it included such containers in the proposed  list of  hazardous




wastes .




     Finally,  the  Agency recognized  that  there were  occasional




spills during  the  transportation  or  storage  of chemicals




which  resulted  in  the contamination  of  soils,  waters and




other  materials, including  debris.   Toxic chemicals  were  no'




more immune to  occasional spills  during  their  manufacture,




storage,  transportation  or  use than  oils; spills with which




the Agency had  considerable experience.   Thus,  the Agency




concluded that  the contaminated spill  clean-up residues and




debris from toxic  chemical  spills, if  not properly disposed




of as  hazardous wastes,  pose substantial  hazard to human




health or the  environment.  Consequently, it included such




residues  and debris in the  proposed  list  of  hazardous




wastes.   In other  words,  while the Clean  Water Act provides




for reporting  and  clean-up  of  spilled  materials of spills




into the  navigable waters,  this RCRA provision requires




management of  spills of  these  listed materials as  hazardous




waste.  Additionally, it provides coverage  for in-plant or




other  spills not within  the scope of the  Clean Water Act




regulations.




                               7

-------
     The Agency's rationale  for  excluding,  from  Subtitle  C




regulation, hazardous waste  generated  by  retailers  and




small quantity generators  is discussed  in a separate  Background




Document.  It is to be noted here,  however,  that  the  proposed




exclusion was based principally  on  considerations applicable




to the other hazardous wastes  listed  in the Proposed  Rules.




Chemical products differ  from  other hazardous  wastes  in two




respects: generally they  are a valuable commodity and therefore




not normally discarded; and, they are  discarded  in  pure,




undiluted form,  which increases  their  risk to  human health




and the  environment if improperly disposed of.   These distinc-




tions led EPA to consider  treating  these  hazardous  wastes




separately.

-------
Response to Comments




General




     A number of commenters misunderstood  the  Proposed  Rules




and assumed that any waste, including manufacturing  process




wastes, containing any  of  the  chemicals  listed  in Appendices




III, IV, V and XII would be a  hazardous  waste.   This  led  several




of these commenters to  urge that  a  quantity  or  concentration




level, below which a waste would  not be  a  hazardous  waste, be




established for  each chemical  listed in  the  Appendices,   Other




commenters urged that,  if  the  Appendices only  applied to  pure




chemicals and then only applied when they  are  discarded,  these




points should be emphasized.   The Agency recognizes  that  the




language of the  Proposed Rules may  have  been confusing.   Con-




sequently, it has  substantially re-written the  provisions,




currently in §261.33 of the Final Rules, and has added  an exten-




sive comment to  clarify the points  raised  by these commenters.




This amplification is  further  discussed  in the  following  section,




Reconsideration  of the  Proposed Rules, of  this  document.




     One commenter urged that  degree of  hazard  be incorporated




in the wastes listed in §250.14(a)  and the related




Appendices.  The Agency's  response  to  comments  on the broad




topic  of the use of degree of  hazard in  the  listing  of  hazardous




wastes is discussed in  a separate Background Document.

-------
Basis for Listing


     A few commenters  seemed  to  suggest  that  Appendices  III,


IV, V and XII should be  used  to  cause  wastes  containing  any
                                                              ,'

of the listed chemicals  to  be  hazardous  wastes.   This  would


essentially change  the list into  a  "characteristic"  with its


attendent responsibilities  for the  generator.   The Agency


did not intend  such a  result.   However,  the Agency has revised


its criteria  for  listing hazardous  wastes  (see  §261.11 of


the Final Rules)  to include this  concept.  The  Agency  has


developed a list  of hazardous  constitutents,  Appendix  VIII,


and will presume  that  a  waste .containing any  of  those  con-


stituents is  a  hazardous waste unless  consideration  of other


factors, such as  quantity of  the  waste,  concentration  of

the  toxic agent or  mobility of the  toxicant,  etc., causes


the Agency  to conclude that the  waste  does not  pose  a  substan-

tial hazard to  human health or the  environment.   This  criterion

requires the  Agency to make a  determination to  list  such

wastes; it  is not the  responsibility  of  the regulated  community


to designate  unlisted  wastes  as  hazardous  wastes because


they contain  materials on Appendix  VIII.  Appendix VIII  does


in fact contain the toxic substances  listed in  §261.33(e) of


the  final rule.   A more  detailed  discussion of  this  criterion


is provided in  the  Background  Document covering §261.11  of


the  Final Rules.

     Several  commenters  pointed  out that the  basis  for listing


each chemical listed in  Appendices  III,  IV and  V was not given;
                               10

-------
rather the generic basis  for  listing was  given  in  the  waste




classes listed in §250.14(a)  where  the  designation of  T,  0 and




M indicated that all  the  chemicals  listed  in  the Appendices




are hazardous because  they  possess  the  toxicity characteristic




and contain toxic organic and carcinogenic, mutagenic  and




teratogenic constituents.   These  commenters noted  that  certain




of the listed chemicals did not meet all  three  of  these  listing




criteria.




     The Agency agrees  and  admits  that  it  should have  placed




the specific basis for  listing with each  chemical  in the




Appendices rather than  in §250.14(a).   In  the final rule, EPA




has classified the basi,s  for  listing the  chemical  products




subject to regulation.  The substances  contained in the




original listings have  been reviewed to determine  whether they




satisfy the listing  criteria. A  table  (Appendix A') accompanying




this background document  indicates  the  disposition of  each




substance  originally  listed.   For  those that  remain on  §261.33(e)




the basis  for such inclusion  is noted.  A  second table  (Appendix




B) indicates the basis  for  listing  of  the  substances on  §261.33(f).




Also noted on these  tables  are references  to  the documentary




material supporting  the inclusions. These documents include




health effects documents  prepared  in support  of these  regula-




tions; materials supporting RPAR  actions;  background documents




supporting National  Interim Primary Drinking  Water Standards,




materials  of EPA's Cancer Assessment Group; data obtained from




the NIOSH  Registry of  Toxic Effects, Sax's Dangerous Properties

Department of Transportation; and,  in  the case of chloro-




fluorocarbons, documents supporting regulations under TSCA.




Single List




     Two commenters  found  the three lists of chemicals (Appendices




III> IV and V) confusing and urged  that they be combined.  The




Agency concurs and has  employed only one list for each




category in the Final Rules, (§§261.33(e) and (f)).






Listing of Off-Specification Materials




     One commenter urged that a clear  distinction be made between




off-specification materials which are  reprocessed rather than dis-




carded and that only the latter be  regulated.  The Final rule has




been clarified to apply only to discarded material.






 Listing of ORM-A Substances




     Several commenters objected  to the listing, in  Appendix IV,




of  chemicals that are classified  by the Department of Transpor-




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




ORM-A materials are  regulated by  DOT because they possess




properties that interefere with transportation safety not because




they are hazardous.   An ORM-A material is one that has an




anesthetic, irritating, noxious,  toxic or other similar  property




which can  cause extreme annoyance or discomfort to passengers and




crew in the event of leakage during transportation  [49 CFR




173.500(a)(l)].  The Agency concurs with this comment and has




not listed chemicals in the Final Rules simply because they
                               12

-------
 are  ORM-A materials.  Rather than adopt the proposed list in




 toto,  EPA has evaluated each substance in accordance with




 the  criteria for listing.  This review has resulted in a




 number of chemicals being listed as acutely hazardous in




 §261.33(e) and hazardous in §261.33(f) or dropped from the




 EPA  lists of hazardous wastes because no data was available




 to the Agency to support such a listing.




      Another commenter objected to Appendix IV, as a whole,




 because it listed chemicals that are hazardous in transportation




 and  not necessarily hazardous at other times.  The Agency has




 listed a number of chemicals in the Final Rules that DOT




 lists as Poison A and Poison B materials.  The basis for this




 listing, however, is not that they only pose transportation




 hazard but, rather, that they are acutely toxic, satisfying the




 acutely hazardous criterion, and present a threat to human




 health and the environment when discarded.






Listing of Containers




      Several commenters were troubled by the inflexibility of the




 triple-rinse provision in the proposed listing of containers in




 §250.14(a).  This provision excluded, as hazardous waste, containers




 of the listed chemicals that had been triple-rinsed.  This pro-




 cedure is an EPA recommended practice for pesticide containers




 (40  CFR 165.9) and also a part of several State programs (e.g.,




 Washington, Oregon).




      Basically, these commenters suggested that there are other




 ways to effectively decontaminate containers.  One suggested
                               13

-------
rinsing with one-tenth volume  of  the  container,  but  did not




specify the type of solution.   Another  recommended incineration




but gave no specifications.  Still  another  pointed out that




the EPA registered label  for the  pesticide,  Malathion ULV




Concentrate, specifies a  rinsing  solution and  procedure that




does not comport with triple rinsing  as  defined  in the Proposed




Rules.  The Agency recognizes  that  there are a large number




of ways for rinsing or otherwise  decontaminating  containers.




Many of these methods are unique  to the  type of  chemical




previously contained by  the  container;  e.g., a specific




solvent should  be used.   As  such,  the Agency has  allowed,  in




the final regulations, persons to  use alternative methods  to




decontaminate containers.  The person may,  however,  be required




to demonstrate  that these methods  are equivalent  to  triple




rinsing.




     One commenter suggested that  the weight of  the  container




itself  be considered in  establishing  the small quantity generator




exclusion limits proposed in §250.29.  EPA  does  not  agree  since




the size of the container, i.e.,  those  containers which may be




used by the public for other purposes--e.g., trash cans,




barbecue pits,  etc.—is  the  real  concern not the  weight of the




container.  However, the  Agency does  consider  the weight  of




inner liners to be an important factor  in  setting a  de minimis




quantity and, thus, has  given  consideration to the weight  of  such




inner liners in establishing the  small  quantity  cut-offs  for




small quantity  generators.
                               14

-------
Listing of Spill Residues  and Debris

     One commenter urged that small amounts  of  contaminated

spill clean-up residues and  debris be  excluded  from  the  listing

of these wastes under  §250.14(a).  The  Agency has  provided such

an exclusion  for aggregate amounts of  residue and  contaminated

debris less than 100 kilograms  (220 pounds).  This exclusion

is provided in §261.4(c)(4)  and  is discussed in the  following

section of this document.

     Another  commenter urged a more precise  definition of spill

clean-up debris to avoid including wrecked rail cars and damaged

trucks as hazardous waste.  The  Agency  does  not know how to

define debris  to avoid the consequences  noted by the commenter.

It believes that it can rely on  the reasonable  implementation

and enforcement of this provision  by EPA and State personnel to

avoid absurd  results.  The difficulty  in providing a precise

definition is  that occasionally  large  equipment is severely

contaminated  by spilled material.  For  example, this could

occur in a spill of toxaphene which is  an extremely  toxic

chemical.  The Agency  assumes however,  that  in  virtually all

cases, heavy  equipment can be decontaminated and need not become

part of contaminated debris.  If it cannot be decontaminated

it must be treated as  a hazardous  waste.
                                  &
Modification  of the List of  Chemicals

     Several  commenters urged that procedures be available to

add to or delete from  the  list  of  chemicals  in  Appendices III,

IV, V and XII.  The Agency believes that revisions to the list

of chemicals  (now in §§261.33(e) and  (f)of the  Final Rules)

                              15

-------
should be achieved only  through  rulemaking.   For  this purpose




and to enable modifications  to other  parts of  the  Subtitle C




regulations, the Agency  has  provided  procedures for petitioning




the Agency  to make revisions  through  rulemaking.   These  procedures




are established in §260.20 of the  Final  Rules.




     Importantly, deletions  from the  lists of  chemicals  in




Appendix VIII and §261.33 are not  available  through the  delisting




procedures  established in §260.22.  The  §260.22 delisting




procedures  are designed  and  intended  to  apply  to  individual




generation  sites to  enable the administrative  delisting  of




wastes that are fundamentally different  from those listed in




§§261.31 and 261.32.  The primary  difference would be that the




waste did not contain the constituent of concern  (or contained




it in such  low concentrations that the waste was  not hazardous);




or other information could be provided by the  generator  to demon-




strate significant differences in  the persistence, bioaccumulation




potential or mobility potential  of the hazardous  constitutent;




or significant differences in the  quantity or  composition of




the wastes.  The Agency  does  not believe that  the  list of




chemicals in §261.33 present  many  opportunities for fundamental




differences because  they are  essentially pure  chemicals  whose




toxicity, concentration  of toxic species, persistence, degra-




dation potential and bioaccumulation  potential are fairly well




defined.  Spill residues of  these  materials  might  vary in con-



centration, of course.   This  fact  led the Agency  to establish




larger quantity cutoffs  for  spill  residues of the  acutely
                               16

-------
hazardous materials listed  in  §261.33(e).   Delisting procedures




are not an appropriate manner  of  handling  spill  residues and




debris because they generally  present  unique,  rather than




recurring, situations.




     With respect  to  those  species  listed  in  §261.33(e), the




chemical substances are  acutely  toxic  or otherwise acutely




hazardous chemicals which  pose a  substantial  hazard in  even




very small quantities (see  discussion  in following section).




Hence, variable  quantities  is  not a fundamentally different




factor for these wastes.   As  such,  the Agency believes  that




any difficulties the  generator has  with those commercial




products listed  in §261.33  should and  can  reasonably be




considered and resolved  in  the rulemaking  process, such that




the delising  procedures  set out  in §260.22 are not amenable




for these types  of wastes.
                               17

-------
             RECONSIDERATION OF THE PROPOSED RULES



Criteria for Listing




     As discussed in the Background Document covering the criteria




for listing hazardous waste and in response to the overall




criticism by commenters of the proposed criterion for listing




hazardous waste in §250.12(b)(2) of the Proposed Rules, the




Agency has expanded and added considerable specificity to the




criteria for listing hazardous waste  in §261.11 of the Final Rules,




One of the final criteria established  (§261.11(a)(2), enables the




Agency to list acutely  toxic or otherwise acutely hazardous




wastes in Subpart D and designate these wastes as Acute




Hazardous Wastes (having a Hazard Code of H).  This  criterion




enables the Agency to list a hazardous waste because it has




been found to be fatal  to humans in low doses or, in the absence




of data on human toxicity, it has been shown in studies to have




an oral LD50 toxicity (rat) of less than 50 milligrams per




kilogram, an inhalation LC50 toxicity  (rat) of less  than 2




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




less than 200 milligrams per kilogram  or is otherwise capable




of causing or significantly contributing to an increase in




seriously irreversible, or incapacitating reversible, illness.




This criterion was established, in response to commenters




who suggested the need  for a specific  criterion for  listing




the substances, principally to define  the basis that the




Agency used in listing  in the Proposed Rules the wastes and
                               18

-------
the related chemicals discussed  in  this document.*  Accordingly,


this change in the final criteria for listing establishes an


explicit basis for the listing of hazardous waste in §261.33(e).


     The chemical substances listed in §261.3'3(f) do not


meet the criteria for listing as an acutely hazardous waste but


rather meet the criterion  for listing, either because it


satisfies §261.11(a)(1), exhibiting identified characteristics,
               «

or §261.11(a)(3), satisfying the toxic criterion.  This latter


criterion directs the Administrator to consider a list of


factors to determine whether a waste containing toxic constitu-


ents listed in Appendix VIII is  hazardous.  Several of these


factors are largely  irrelevant in examining chemical substances


in their pure  form because  the constituent in this case is the


waste.
                           +

Changes in the Listing of  Chemicals


     In response to  comments, the lists of chemicals proposed


as Appendices  III, IV, V and XII have been combined and simplified.


Section 261.33(e) is a listing of commercial chemical products or


manufacturing  chemical intermediates which because they pose


a severe acute hazard in small quantities, must be managed


as a hazardous waste in quantities  at which most hazardous


waste is exempted.   Section 261.33(f) consists of hazardous


substances for which the §261.5(a)  and (b) small quantity


exclusion limit is believed to be adequate to protect public


health and the environment.
 * However, this criterion also may be used by  the Agency to

   list hazardous wastes in §§261.31 and 261.32.


                              19

-------
     In addition, the Agency has substantially modified  the final

list of chemicals.  First, it has listed only commercial chemical

products or manufacturing  chemical  intermediates, chemicals that

are not normally discarded.  The reason for  this is that

§261.33 is exclusively designed to  regulate  these materials in

the event they are discarded or intended to  be discarded,

are discarded as off-specification  materials, are discarded

as residuals in containers or inner liners of containers or

are spilled.  Where the Agency's interest in a chemical  is

because it is a hazardous  constituent  of a solid waste,  the

Agency will list the wastes  or classes of wastes that  typically

or frequently contain such chemicals in §§261.31 and 261.32*.

The principal effect of this approach  has been to eliminate,

as a class, the chemicals  listed in Appendix V which derived

from a list of toxic chemicals that are typic'ally found  in

industrial wastewaters, or as constituents of wastes.

     The second major change has been  to make the listing of

chemicals under §261.33 of the Final Rules comport  to  the

listing criterion of §261.11(a)(2)  and (a)(3) i.e., those

wastes which present an acute hazard or present a hazard to

human health if improperly managed. Commercial chemical

products or manufacturing  chemical  intermediates are not

normally discarded.  However the Agency is concerned with

controlling those chemicals  which when discarded, no matter

how infrequently, could pose a potential hazard.  The  Agency,
* Hazardous compounds  that  are  a  concern  because  they  are
  constituents of  solid wastes  are  listed in  Appendix  VIII  and
  are used under §261.11(a)(3) to  list such wastes as hazardous

wastes.

-------
in this initial promulgation, therefore, is  limiting  this

list of chemicals to those which could present an hazard

only to human health.  Accordingly, under  §261.33(e)  only

commercial chemical products or manufacturing chemical inter-

mediates that have been found to be fatal  to humans in low

doses or, in the absence of data on human  toxicity, have been

shown in studies to have an oral LD50 toxicity (rat)  of less

than 50 milligrams per kilogram, an inhalation LC50 toxixity

(rat) of less than 2 milligrams per liter, or a dermal LD50

toxicity (rabbit) of less than 200 milligrams per kilogram are

listed in §261.33(e).  This change has had the effect of removing

the following groups from the proposed list:  the ORM-A materials

listed in Appendix IV of the Proposed Rules, the cancelled and

RPAR review pesticides listed in Appendix  III, and the known

or  suspected human carcinogens listed in Appendix XII of the

Supplemental Proposed Rules.*  Further, under §261.33(f) only

those commercial chemical products or manufacturing chemical

intermediates which may present a potential  hazard to human

health, if improperly managed and for which  the Agency has

sufficient data to make a determination are  listed.   Each

chemical was individually reviewed to determine whether it met

the acutely hazardous criterion of §261 .ll(a)(2), the toxic

criterion of §261-11(a)(3), or met the identified characteristics

of hazardous waste.
 * This change has not  removed  the  Po.ison  A  and  Poison  B  materials,
   listed in Appendix IV  because  these  are substances  that  have
   an LD50 or LC50 toxicity  that  meets  the criterion  for  listing.
                               21

-------
     In summary, the combined effect of the two changes

described has been to convert the original list of about 300

chemicals listed in Appendices III, IV, V and XII of the

Proposed Rules to 122 chemicals in §261.33(e) and 239 chemicals

in §261.33(f).  Several of the substances in the proposed rules,

for which data was lacking, are currently undergoing review to

determine whether listing on either §261.33(e) or §261.33 (f)

is appropriate.  Appendix A to this document provides a

tabular display of these changes.

Rationale for Selecting Acutely Hazardous Criteria

     The chemicals on the promulgated  list under §261.33(e)

are listed because of one or more of the following criteria:

     1.  acute oral toxicity

     2.  acute inhalation toxicity

     3.  acute dermal-toxicity

     4.  extreme reactivity (explosivity)

     5.  capable of causing or significantly contributing to
         an  increase  in serious irreversible, or incapacitating
         reversible,  illness*

Chemicals listed for  acute oral toxicity have been found to

either be fatal to humans upon ingestion of <_ 100 mg/kg or to

have an oral LD50 toxicity to rats of  less than 50 milligrams

per kilogram.  Chemicals that have these levels of toxicity are

extremely powerful poisons.  For example, ingestion of less than


*Thiscriterion was not used in listing the commercial chemical
 products or manufacturing chemical intermediates in Section
 261.33(e),  and therefore will not be  further discussed- in  this
 document.
                               22

-------
 a  teaspoonful of these chemicals would be fatal to an adult*.

 Additionally, lesser amounts can be expected to cause illness

 or even death to children and to more sensitive members of the

 population.   As can be readily surmised, indiscriminate disposal

 of such chemicals could be highly dangerous.  Any number of

 injury scenarios could result; e.g., accidental contact and

 ingestion by children or pets (not unlike situations at Love

 Canal); contamination of worker's clothing and resulting

 ingestion of small quantities rubbed off the clothing; and

 inadvertent  contamination of foods or drinking water,

 particularly from residuals in containers or from spills.

 Because of the acute toxicity of these chemicals, the Agency

 has concluded that they very definitely meet the listing

 criteria of  §261.ll(a)(2 ) and also §261.11(a)(3) .

      The acute inhalation toxicity is based on an inhalation

 LC50 of less than 2 milligrams per liter.  Chemicals having

 these levels of toxicity also are extremely effective poisons.

 For example, less than 0.2 ounces of such a material are

 sufficient to lethally contaminate the air of an average

 size (12' by 12' by 8') room.  Indiscriminate disposal of

 such chemicals could result in any number of dangerous

 scenarios; e.g., contamination of the air in refuse collec-

 tion bins and trucks posing a danger to workmen; subsurface

 migration of such chemicals into the basement of homes, result-

 ing in injury to the inhabitants, such as occurred at Love Canal;
 *Based on toxicity to rats and humans being the same.  The
  human is considedred to generally be more sensitive than
  the rat due to its higher surface to weight ratio.  Using
  a surface-area weight relationship for the two species, the

  rat is expected to generally  be only one-sixth as  sensitive

as the adult  human.
                            23

-------
contamination of the air of enclosed structures when  salvaged




containers having residues of  these chemicals are opened; and




injurious human exposure to these  chemicals in certain spill




or spill clean-up situations.  Because of  the acute toxicity




of these chemicals, the Agency has concluded that they also,




very definitely, meet the listing  criteria of §261.ll(a)(2)




and also §261.11(a)(3).




     The acute dermal toxicity is  based on a skin absorption




LD50 toxicity of less than 200 milligrams  per kilogram.  Like




those above,  chemicals having  these levels of toxicity are




extremely poisonous and both indiscriminate and uncontrolled




discriminate  disposal can pose injury scenarios similar  to




those described above.  In fact, the dermal route of  exposure




is of major concern since, like  inhalation, it can readily




occur, as for example, as a result of contact of children




and pets with the substance and  contamination of worker's




clothing.  Accordingly, the Agency has concluded that these




chemicals meet the  listing criteria of §261.11(a)(2)  and also




§261.11(a)(3).




     The Agency has used three sources of  toxicological




information in determining the LD50 and LC50 toxicities  of




chemicals.  These are:

In using these references, the Agency has only used citations

     The extreme reactivity (explosivity) effect is based on



well known properties of the chemical.  Three chemicals are



listeti in §261.33(e) for this reason.  Each of these is well



known as being explosive under standard temperatures and



pressures.  Mild shock is sufficent to cause an explosion and



potentially result in severe injury or death to humans and other



life forms.  These three chemicals were not on the proposed list



but would have been hazardous wastes under the proposed




reactivity characteristic.



     The chemicals listed in §261.33(e) are all commercial



chemicals and chemical intermediates.  The chemicals are listed




in §261.33 by their IUPAC (International Union of  Pure and



Applied Chemistry), or in certain instances by their



generic, name.  In addition, for the convenience of those using




these regulations, where known, one or more common trade names




are given.



     In preparing §261.33(e) the Agency examined the information




available on each of the compounds proposed in Appendices III,


                                              i

-------
inclusion on §261.33(e) are  so  listed.   In  addition,  the Agency




examined the NIOSH "Registry" to  determine  if  there were any




other compounds which met  the criteria.   Given  these  changes




§261.33(e) has been promulgated as  "interim  final"




rules and the Agency will  be accepting  comments on the




appropriateness of these listings.




fisting of Containers




     Section 261.33(c) of  the Final Rules has  been expanded to




address the comments on triple  rinsing.   As  now written,




triple rinsing with a solvent capable of  removing the commercial




chemical product or manufacturing chemical  intermediate is the




standard for Subtitle C regulations by  which a  container can be




rendered non-hazardous.  The limit  for  containers only applies




to the acutely hazardous materials  listed in §261.33(e) because




the residue of these substances in  containers  may be  lethal




in such quantities.  For the other  hazardous materials listed




in §261.33(f), the containers may not prove  hazardous, and EPA




lacks the data to take a general  position on this.  The




regulation does not specify  the type of  solvent to be used in




triple rinsing containers.   Different solvents  may cleanse




chemical product containers  with  varying  results, and it was




impossible for EPA to require the use of  a  particular solvent




for all containers.  In this respect, this  Rule is similar to




the general disposal requirements for pesticide containers




promulgated under FIFRA.   (See  40 CFR §165.9(a)).  In response




to comments, EPA has increased  the  flexibility  of the Rule




by allowing a person to use  alternative  methods to decontaminate







                             26

-------
  a  container,  if the person can demonstrate that such methods




  achieve  equivalent results.  For example, government regulations




  may  authorize a person to incinerate combustible containers




  under  certain conditions, CF 40 CFR §165.9(a), or a manufacturer




  may  recommend that such disposal be employed.  Several commenters




  noted  that certain paper containers could not be triple-rinsed.




  EPA  did  not,  through these regulations, want to prevent people




.  from using these disposal techniques.  The Agency is aware that



  requiring "equivalent" decontamination procedures without




  specifying solvents or procedures provides, at best, a vague




  standard.  The Agency believes that, in most cases, this rule,



  if interpreted sensibly, provides sufficient guidance to both




  the  regulated community and Agency enforcement personnel.  For




  most containers, the manufacturer will specify a particular




  solvent, or it will be assumed that water is the appropriate




  solvent.  Unless the knowledge is already extant—e.g., through




  manufacturer recommendations—it would appear that most persons




  would  triple-rinse with water or other dilution liquid rather
                         •


  than conduct tests to determine the equivalency of their procedures.




  Accordingly,  EPA expects that this alternate procedure will



  not  be widely used and that triple-rinsing will be the standard




  cleansing procedure.



     * Public comments on Part 250, Subpart D of the Proposed Rules




  raised questions about how the regulations should deal with inner




  liners of containers and containers from which the inner liners have




  been removed.  The resulting reconsideration is reflected in




  §261.33(c) as well as in other parts of the regulation.




  Basically, inner liners from containers used to hold chemicals




                               27

-------
listed in §261.33(e) are  treated  like  containers  and  are

hazardous wastes when discarded unless  triple  rinsed  or

equivalently decontaminated.*  On  the  other  hand,  containers

from which the inner liner  has been  removed  need  not  be

considered as a hazardous waste when discarded.

Listing of Spill Residues and Debris

     As previously  discussed  and  in  response to comments,  the

final listing of' spill  clean-up residues  and debris has been

modified to clarify  that  only contaminated debris, including

contaminated water  and  soil,  is covered.  Also, a  provision

has been added to limit this  listing to aggregate  amounts  of

clean-up residues and debris  that  exceed  100 kilograms (220

pounds).  This de minimi s quantity is  based  on the Agency's

best  judgment of an  amount  that will not  overburden the

Subtitle C hazardous waste  management  system,  (including

its implementation  and  enforcement)  and,  further,  will not

pose  a significant  risk to  human  health or the environment.

Based on the Agency  experience with  the cleanup of spills,

100 kilograms—half  a drum—for acutely hazardous  wastes is

a very small amount  and would only apply  to  very  small or

very  limited spills.  Given the acute  hazardousness of the

chemicals listed in  §261.33(e), the  Agency does not believe
                      «
this  quantity is too low.   In fact,  there may be  cases where

lesser amounts pose  substantial hazard.  In  such  cases, the


"*"Typically, inner  liners  are not decontaminated and reused;  they
   are removed from  the container  and  discarded.
                               28

-------
Agency believes it can rely on the discretion exercised by




the trained personnel that typically respond to spills to




require proper management of  these lesser amounts.

pe Minimis Quantity Cut-Off  for  Small Quantities  of  Acutely
Hazardous Materials            ~  ~     ~	~~"	~


     As discussed  in  a  separate  Background Document. §261.5  of

the Final Rules excludes  (from Subtitle  C  regulation)  hazardous

wastes that are generated,  treated  or disposed  of in quantities

less than 1,000 kilograms  (2,200 pounds)  in any 30-day period by

individual small  quantity  generators.  The Final  Rules further

provide that  this  1,000 kilogram exclusion eventually  will be

lowered to 100 kilograms  (220 pounds) in  any 30-day  period.  The

Agency has concluded  that,  whereas  this  exclusion may  be

appropriate and justified  as a general exclusion  for the

variety of hazardous  wastes  listed  in Subpart D,  it  is not

appropriate for the acutely  toxic and hazardous wastes listed

in  §261.33(e).  These quantity limits do  apply  to chemical

products  listed in §261.33(f).  Consequently, §261.5(c) of

the Final Rules provides  lesser  exclusion  limits  for the

commercial products listed  in §261.33(e).

     For  commercial chemical products, manufacturing chemical

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

the dje minimis quantity cut-off  is  one kilogram (2.2 pounds)

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

quantity  generators who discard  more than  one kilogram of

these chemicals in any  calendar  month period must designate

such chemicals as  hazardous  wastes  and these must be managed

as  hazardous  wastes by  the  generator and  all other persons

(transporters and  owners  or  operators of  off-site treatment,

storage or disposal facilities).  This quantity,  in  the

Agency's  best judgment, will reduce the  risk to human health



                               30

-------
and the environment,  from  the  discarding of  these wastes,




to a very low level  (the limit of  only one kilogram is  a




stringent requirement  for  persons  handling these  products  in




the course of business).   The  Agency recognizes  that lesser




quantities of these  chemicals  can  be hazardous.   As indicated




above, only a few  ounces of  these  chemicals  can  be lethal  or




injurious.  At  the same  time,  the  Agency recognizes the




implementation  and enforcement of  small quantity  requirements




will be difficult.   It will  be difficult to  inform all  potential




generators of the  final  requirements and it  will  be virtually




impossible to monitor  and  police the discarding  of small




quantities.  The Agency  has  balanced these two competing




consequences and has concluded that the quantity  selected  is




a  reasonable compromise, particularly when -it  applies only




to  small  quantity  generators.   These de minimis  quantities




do  not apply to other  generators who must manage  all quantities




of  §261.33 commercial  products ds  hazardous  wastes.




     For  containers (except  the inner liner  of containers  that




have been removed) that  are  not triple rinsed  or  otherwise decon-




taminated, §261.5(c)(3)  provides that the de minimis quantity




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




Persons who discard larger containers must manage them  as




hazardous waste.   The  Agency chose 20 liters because it




believed  that there was  a  larger probability that such




containers, when discarded,  might  be salvaged  for use as




trash cans, barbecue grills, storage containers  and other
                            31

-------
items where human exposure  and  consequential  injury  could


occur.  It reasoned  that  there  would  be  a  lesser  probability


of salvaging of small  containers  because there  is  less  utility


for such containers.


     For inner liners  of  containers which  have  been  removed and


are discarded; §261.5(c)(4)  provides  a  de  minimis  quantity cut-off


of 10 kilograms (22  pounds).   Jhe same  reasoning  as  used


for the pure chemicals and  off-specification  materials  was
    «

used  except  that  adjustment was made  for the  assumed weight of


the liner.   Again,  the decision was based  on  the  Agency's best


estimate about the  probable risk of  injury.


      For the clean-up  residues and debris  from  spills,  §261.5(c)(5)


provides a  100 kilogram (2,200 pound) de minimis  quantity cut-off


(per  spill  event).   The rationale for this choice  is discussed


previously  in  this  document.

 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

          (3)    In the  case  or  a container,  the  inner liner  that

prevented contact of the  commercial  chemical  product or
                                 81

-------
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.]
                                82

-------
     (e)  The commercial  chemical  products  or manufacturing  chemical

intermediates, 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(c).
