 SUBJECT  RCRA  Regulatory Status of Contaminated  Groundwater

        Office of  Solid Waste (WH-562)

        James Scarbrough, Chief
        Residuals  Management Branch,  Region IV


          The memo dated July 20,  1984,  which  you retransmitted
      December 1,  1984, explores the  regulatory status of contaminated
      ground  water.   Actually, the  issue  is not whether groundwater
      that contains Appendix VIII constituents  is a hazardous waste,
      because generators  do  not use Appendix VIII bo» identify hazardous
      waste.   Rather,  EPA designates  solid wastes that contain Appendix
      VIII constituents as  listed hazardous waste after considering
      the  criteria listed in 40 CFR §261.11(a).  Then a generator
      identifies hazardous  waste using  the criteria listed in 40 CFR
      §261.3(a)  and the decision matrix of 40  CFR §262.11.

          Thus, to answer  the question:  "Is ground water contaminated
      by hazardous waste  considered to  be hazardous waste?" one uses
      the  criteria in  §261.3 to see if  the water was a solid waste,
      and  either derived  from listed  waste or  hazardous by characteristics
      identified in Subpart  C.  Note  that §261.3(c)(2) says that any
      solid waste  generated  from the  treatment, storage or disposal of
      a  hazardous  waste is  a hazardous  waste,  and §261.3(d) says a
      waste  is no  longer  hazardous  when it no  longer exhibits the
      characteristics  of  hazardous  waste  identified in Subpart C or
      until  a listed waste  (or waste  derived from listed waste) has
      been excluded under the petitioning process.
           Therefore a contaminated  groundwater that is "collected"
      and  derived  from listed waste  or hazardous by characteristic
      is a hazardous waste and subject to Subtitle C regulation.
      However,  the reauthorization bill allows  underground injection
      of contaminated ground water that has been treated to substantially
      reduce  the hazardous constituents.

           Of course, the implications on permitting, interim status
      coraplianrce order corrective actions, and  treatment of ground
      water will need to be studied.  If  you have any further questions,
      do not  hestitate to contact Irene Horner  of my staff at 382-4804.

                RCRA/SUPERFUND HOTLINE MONTHLY  SUMMARY

                                 DECEMBER  85
Burning and Blending

8.   A generator of used oil^bums the used oil on-site in an industrial Doiier.
    The used oil neither exhibits a Subpart C characteristic of a hazarcous waste
    nor exceed* any of the specification levels listed in §266.40(e)  (Novemcer 29,
    1985,  Federal Register (50 FR 49164)).  If the generator olends unused product
    xylene (hazardous waste number U239) into the used oil, does he then  have a
    hazardous waste fuel (per §261.6 (a)(2)(ii)) which is subject to regulation
    under  Subpart D of Part 266?

        Xylene is a comercial chemical product listed in $261.33(f).  U.S. EPA
        has determined, however, that listed commercial chemical products are not
        solid wastes (or hazardous wastes) when burned for energy recovery  if
        they are themselves fuels or normal components of commercial fuels per
        §261.33 which states that such materials are not "discarded",  and restated
        in footnote 8 of the November 29, 1985, Federal Register (50 FR  49168).
        Xylene is a normal component of fuel.  Therefore, the unused xylene is
        neither a regulated solid waste nor hazardous waste when burned  for energy
        recovery.  The generator's used oil has not been mixed with hazardous waste
        and is not a hazardous waste fuel.  Therefore it will not be subject  to
        Part 266, Subpart 0 regulation per $261.33 and 261.6(a) (2)(ii). The
        used oil, however, is being burned for energy recovery and so is regulated
        under Part 266, Subpart E, per §266.40(a).  section 266.42 states  that
        generators who burn used oil are subject to $266.44.  The burner must
        notify under Section 3010 of RCRA for his used oil management activities
        and maintain documentation or analysis showing that the used oil meets  the
        specifications.

Dear Mr. Slemmeri

     Thi« is in response to your letters dated November 27
and December 27, 1985, concerning the identification of
residues generated fro* the treatment of haiardous wastes.
In particular, you ask whether the identifiction numbers that
go on the manifest that accompanies the treated waste should
be based on the hazardous waste characteristics of the treated
waste, the composition of the treated waste, or both.

     The answer to this question depends both on which wastes
are being treated and the characteristics of the treatment
residue,  if the TSD facility is treating only characteristic
hazardous wastes, the identification number that goes on the
manifest for the treatment residue would be that number that
is assigned to the characteristic for which the waste still
exhibits (i.e., if the treated waste exhibits the characteristic
of ignitability, the identification number would be 0001).
Of course, if the treatment residue no longer exhibits any
of the characteristics of hazardous waste, the waste would
no longer be hazardous and subject to Subtitle C control.
If, on the other hand, the treatment facility treats both
listed and characteristic hazardous wastes or just listed
hazardous waste, the identification number that goes on the
manifest for the treatment residue would be that of the
untreated listed waste and that number that corresponds to
the characteristic for which the waste exhibits, if any.
Thus, in thrn example provided in your letter, you are correct
that the identification number for the treated residue is
U012.  You are also correct that the TSD becomes a generator
of the treated waste.

-------
     I hope this adequately responds to your request,   if I
can be of any further assistance/  please feel free to  give »e
a call at (202)  475-8551.

                                   Sincerely,

MEMORANDUM


SUBJECT!  Oisoosal of Anti-Neoplastic Agents in Hospital Wastes

PROrtj     Jeff Denit, Deputy Director
          Office of Solid Waste (WH-562)

TO:       Kenneth D. Feigner, Chief
          EPA, Reqion X
          Waste Management Sranch

     The issue regarding possible hazards nosed by anti-neoplastic
drugs has been brought to our attention within the last couple of
years,  t/ith large increases in both the numbers of anti-neonlastics
available for use in chemotherapy and the number of patients beinf
treated with these drugs, hospital personnel have expressed con-
cern with handling and disposal of these chemicals (and materials
contaminated with these chemicals).

     Anti-neoplasties, as a class of chemicals, are not regulated
under RCXA.  However, the following are list >1 as hazardous waste
under 40 CPR. 261.33{f)s
             Chlorarabucil
        J05d Cyc 1 ophosphamide
        UOS9 Daunonycin
        U1SO Melphalan
        U010 Mito?aycin C
        U206 Strsptosotocin
        U237 Uracil -auatard

     However, since these wastes  are  identified  only as "toxic"
wastes, under $261.22(f) they are subject  to the standard
snail quantity generator exclusion.   As  a  practical -nattar, thi^
means that unless  large volumes of these chenicals are dlflc^rde^.
( i.e.,  100 fcg/Dto or -aore) which  in nost  cases  is -onliicelv, or
the facility is a  large quantity  generator, the  majority o€
these waste* will  rsnain unregulated.

     The Agency is aware that manufacturers and  health care
facilities recoaaend  incineration of  anti-neoplasties and materials
contaminated with  these chemicals*  Although there is no concensus
anong health care  professionals  as  to the  appropriate temperature

-------
necessary for destruction, nuiny facilities are incinerating
these wastes at temperatures between 18QO**2200*P.  Sine*
the Agency has not investigated the efficiencies of incineratinq
these wasts)«» we have, not provided guidance or taken a position
with respect to this issue.

     At this tiae, we have no plans to conait resources to the
study of anti-neoplasties or to initiate any further rulemakinq
action,  ^e recommend that State officials (in Seattle) contact
the manufacturers of these drugs to gather information on recom-
mended handling and disposal practices.

SUBJECT;  Carbon Regeneration Facilities

PROM:      Marcia Williams, Director
          Office of Solid Waste (WH-562)

TO:       Stephen R. Wassersug, Director
          Hazardous Waste Management
           Division (3HWOO)
     This Is in resoonse to your March 11, 1986, memorandum
regarding the applicability of the RCRA hazardous waste rules
to carbon regeneration facilities.  In oarticular:

  1} Is the spent carbon a solid waste?

     In general, yes.  As you correctly state  in your
letter, spent carbon can be defined as a spent material or a
sludge (i.e. , spent carbon would normally be considered a
spent material, unless it results from pollution control in
which case it is considered a sludge).  Scent materials
(whether or not they are listed or contain a listed hazardous
waste) and listed sludges being reclaimed are  solid waste.
In addition, if the spent carbon contains a characteristic
spent material (and the spent carbon  itself exhibits a hazardous
waste characteristic)* it also is a solid waste.  On the other
hand, if the spent carbon contains a  characteristic sludge
or by-oroduct, it is not defined as a solid waste (even if the
spent carbon exhibits a hazardous waste characteristic).

  2) Is the spent carbon a hazardous  waste?

     Yes.  That spent carbon defined  as solid  waste (as
described above) is also hazardous if it contains a listed
hazardous waste or exhibits a hazardous waste  characteristic.

  3) Which Part 264 standards apply?

     If the spent carbon  is a solid and hazardous waste,
the owner or operator of the facility must comply with the

Honorable Richard G. Luqar
United States Senate
Washington, D.C..  20510

Dear Senator Luqar;

     Thank you for your letter or April 9, 1986, concerning the
Union Carbide facility in Henderson County, Kentucky.  You asked
about the location ot the plant and the listing ot TF-1 under
the Resource Conservation and Recovery Act (RCRA).  I would like
to tirst clarity my understanding of the proposed Union Carbide
operation.

     Union Carbide has applied for a permit to recycle TF-1, used
as a flushing agent in electrical transformers, th«t has been
contaminated with PCBs.  Solid waste frost this recycling process
will be transported oft-sita to a permitted TSCA facility for
incineration.  The TF-1 will tx» processed at the Henderson facility
after Union Carbide drains and flushes the transformers at its
customer's site.

     The State ot Kentucky issued Union Carbide a construction
permit under the authority ot the State's Air Pollution Control
Act in December 1985.  Union Carbide also applied to CPA for a
Toxic Substances Control Act (TSCA) permit.  Union Carbide submitted
its application to EPA's Region IV office in February 1986 and a
test demonstration plan in early April 1986.  Both subraittals are
now under review by the Region.  TSCA requires that EPA consider
location during this review to ensure that permit issuance would
not constitute an "unreasonable risk* to human health and tho
environment.  In addition, due to citizen and Congressional concerns,
EPA Region IV is voluntarily conducting a public health and environ-
mental assessment of the area surrounding the facility.

     Prior to operation, Union Carbide must successfully conduct
demonstration testing, and secure a TSCA operating permit and a
Kentucky Air Pollution Control Act operating permit.  Once in
operation, the facility must conduct routine testing to ensure
permit standards are continually met.

     Secondly, I would like to clarify why the information presented
by Dr. Howard E. Dunn is not sufficient in itself to list TF-1 as
a hazardous waste.  The possible inclusion of one or more ot the

-------
chemical constituents of TP-1 in 40 CFR 261.33 would not auto-
matically m«fc« a mixture of those constituents a hazardous waste.
This "listing* refers only to the commercially pure grade ot the
chemical, any technical grades ot the chemical that are produced
or marketed, and all formulations in which the chemical is the
sole active ingredient.  Thus, TF-1 could contain a constituent
listed TnTO CFR 261.33 and not be a hazardous waste.  I cannot
comment on the specific chemical composition of TF-1, due to
regulations concerning confidential business information.

     In order for EPA to promulgate a rule listing a waste as
hazardous, factors in addition to toxicity must be considered.
These include the concentration of the constituents, quantity of
waste generated, the persistence and potential of the constituents
to migrate from the waste and move into the environment, and the
plausible types of mismanagement to which the waste may be
subject.  Based on these factors, a waste will then be "listed"
when the data allows the Agency to conclude that the waste nay
pose a substantial present or potential hazard to human health
or the environment when Improperly managed.

     Because of the absence of existing data in this area, EPA
has scheduled toxicity tests for several of the TP-1 components.
Once this testing is completed, a determination can be mad* on
whether these constituents are hazardous and whether the waste
should be listed.

     If you should have specific questions on the permitting
process, you may wish to contact Connie Jones, EPA Region IV
(404-881-2091), or J. Alex Barber, Kentucky Department of
Environmental Protection (502-564-6716).  Please let me knov
if you have any turther questions.

                                       Sincerely,

     four inquiry of April 22, 1986 has been referred  to  the
Cnaracterization and Assessment Division of the Office  of Solid
Waste.
       A has evaluated the relative carcinogenic potencies  anonq
54 suspect huiaan carcinogens.  These are published  in t\any  of
the Hoalth Assessment Documents developed by the Office  of  Health
and Environmental Assessment (OHEA).  I have e.nclosed a  copy of
such a table from a recent Health Assessment Document for tetro-
chloroathylene.  For further information concerning other susoect
carcinogens, mutageua, or teratoqens, I suggest you contact Mr*
Peter sreuss, Director of OHEA.  He can be reached  at (202)
3J2-7315.

     The Office of Solid Waste uses this health assessment
information along with other evaluations of potential exposure
ana mismanagement in making a regulatory decision on whether
a waste is hazardous.  The criteria EPA uses are codified at
40CFrf Sections 261*10 and 261.11, a copy of which is alco en-

General Counsel

Buffalo, NY  14203

Dear Mr. Ginqold:

     This is in response to your letter of June 12, 1987, in which
you requested clarification regarding waste tracking and classifi-
cation.  First, I would like to apologize foe taking so long in
responding to your letter; I hope my delay hasn't caused you any
problems.  The answers to your questions are as follows:

     1.  BPA's current policy on mixing low and high 3tu wastes
         is summarized in an enforcement guidance memo published
         in the Federal Register of March 16, 1983.  (Enclosure
         1.)  As the guidance meao explains, a determination of
         what constitutes 'sham burning" depends on a number of
         factors presented by the circumstances of a particular
         case; the energy value of the wastes being blended or
         burned is likely to be of primary significance in most
         cases.  Blending a low Btu waste (i.e., less than 5000
         Btu/lb.) with a higher Btu waste would not normally
         change the "sham* character of the subsequent burning.

         YOU should note that, as toe guidance memo points out,
         other factors are considered in distinguishing sham from
         legitimate burning, and that l?A will set a priority on
         sham burning in non-industrial settings*  Also, as you
         correctly point out, SPA has proposed a new fuels policy
         ia the) for* of revisions to the hazardous waste burning
         i «• lit Inns   on May 6, 1987, BPA proposed standards Cor
         botft*rs snd furnaces burning hazardous waste,  (see Bn-
         clfpi*e> 2.)  The proposed standards would apply to boil-
         ers) smd furnaces burning hazardous waste regardless of
         whether the purpose was energy recovery or destruction,
         so the "sham recycling* distinction would no longer be
         relevant.  (Zd. at 16989.) BPA has accepted public coo-
         men ts on the May 6 proposal and we will be making deci-
         sions regarding the final rule within the next year.
         Ontil this regulation is made final, the enforcement
         policy will remain in effect.

-------
                               -2-
         A3 a final oont on burning of wastes, you should note
         that th« u.s. Court of Appeals for the District of col-
         •i -Jbi'-J reached ^ Decision'on July 31, 1987,  chat calls
         into question EPA'S authority to regulate certain waste
         rscyclinq activities.   SPA is studying the opinion to
         3eter.75ine its scope.   because the Court has not yet
         issued its nandate, the regulations currently in the
         Code of Federal Regulations defining what is "solid
         waste," and establishing regulation* for recycled
         hazardous waste, remain in effect.

     2.  Listed wastes never "lose their identify.*  Wastes are
         tracked on the manifest by waste code under O.S. Depart-
         ment of Transportation (DOT) regulations at 49 CFR parts
         171 and 172.I/  For mixtures, you aust enter each waste
         code in the mixture on the manifest.  Further, you should
         note that facilities  in interim status must specify on
         their ''Part A" permit application the hazardous waste
         they will be receiving (see 40 CPR S270.13(j)> and must
         amend the Part A to receive new wastes (S270.72(a».
         Also, a HCRA permit granted to a treatment, storage, or
         disposal facility nay specify the specific hazardous
         wastes the facility is authorised to accept.  Finally, a
         treatment, storage, or disposal facility aust keep an
         operating record with very specific information on each
         hazardous waste at the facility.  (See SS264.73 and
         265.73.)

     3.  All of the requirement* referenced in answer number 2,
         above, require tracking of individual wastes by shipment
         (and if n«cec«ary, by container).

     4.  The proper classification of waste treatment residuals
         (the filter cake in your case) depends on the wastes enter-
         rimg your treatment system.  Under 40 C7R S261.3(c){2)(i),
         am? waste derived-from treating a hazardous waste is
         its»lf a hazardous waste.  Such "derived-from* wastes
\/ Please not* a couple of points regarding waste shipment tracking.
   First, the DOT rules referred to above do not require the EPA
   waste code for •&* and "P" listed wastes.  This is because U
   and P chemicals must already be described by their specific
   chemical names under 49 CFK Fart 171.  You should also note that
   although EPA does not require the 1PA waste codes to be placed
   on the hazardous waste manifest, some States do require BPA's
   (or their own) codes to be entered oa the manifest in addition
   to the DOT requirements.

Dear Mr. Boulware

     This  is  in response to your May 27, 1986 letter, requesting
an interpretation of the Federal hazardous waste rules as they
apply to the wastes to be generated in your extraction process.
As you state in your letter, this process uses the solvent
methylene  chloride to recover alkaloids from plant matter.
The two wastes for which you request specitic inrormation on
are:  (1)  the solid cake remaining in the basket centrifuge,
and (2) the wastewater stream discharged to a POTWc

     Solid Cake -  I agree with your understanding that the
     solid cake in the basket is not a listed hazardous waste,
     namely, a spent solvent—and would only be hazardous it
     it exhibits any of the hazardous waste characteristics
     (i.e., ignitability, corrosivity, reactivity, or extraction
     procedure (EP) toxicity); in addition, when the TCLP is
     promulgated, you will also need to determine: whether the
     solid cake exhibits this characteristic.

     Wastewater -  This wastestream, as you state in your
     letter and as we discussed on June 27, cones off the
     centrifuge as a wastewater that contains methylene
     chloride; the methylene chloride is then stripped ott to
     be reclaimed while the wastewater is discharged to a
     POTW.  Under this scheme, the wastewater also is not
     considered a listed waste (nor does it contain a listed
     waste).  Therefore, this stream also would only be
     hazardous if it exhibits any of the existing or future
     hazardous waste characteristics.

     Finally, although you did not request an interpretation
of the status of the spent methylene chloride under the
federal hazardous vaste rules, you should be aware that the
spent methylene chloride that comes ott the liquid extractor
is considered a listed hazardous waste and may be subject to
regulation under Subtitle C of RCSA.  (See the Final Definition

the Final Tank Rules that were signed  by the Administrator
on June 30,  1986,  to determine the actual regulatory status
of the solvent spent methylene chloride.)

     Please  feel  free to give me a call if I can be of any
turther assistance;  my telephone number is (202) 475-3551.

Dear Ms Matey:

     I would like to sumarize the information you discussed with Eileen Claussen
during your phone conversation regarding the Office of Solid Vteste's program
for relisting hazardous wastes. Our goal is to amend the current hazardous
waste listings so that their applicability can be better detined; our current
thinking is to redefine the listings by setting concentration limits (either
in the waste or in the leachate fron the waste) for the various toxic constituents
currently identified or expected to be added in Appendix VII of Part 261.
That is, waste or leachate fron the waste that contains the toxic constituents
of concern below the levels to be set in the amended listings, would no longer
be designated as a listed hazardous waste; the waste would still tip hazardous,
however, if it exhibits one or more of the hazardous characteristics detined
in 40 CFR 261.21-261.24.

     Based on a review of the available data, the Agency has identified the need
to obtain additional constituent concentration data for the currently listed wastes
in order to determine the level at which the constituents of concern could present
a hazard.  Thus, we plan to visit a nunber of facilities generating the listed
hazardous wastes, and collect samples of these streams for analyses.  We are in
the process of identifying plants to visit and will contact those plants within
the next few weeks to make arrangements for sampling this fall.

     He encourage your members to submit any available data on waste or leachate
composition, ground water monitoring, and toxic effects that will help the Agency
establish appropriate concentration levels for toxic constituents in their wastes.

     Your cooperation and assistance in this effort will be appreciated. Should
you have any questions regarding this program or need additional information,
please contact me at (202) 382-4766.

                                     Sincerely,

Mr. Richard Ekfelt
Director of Regulatory Affairs
American Coke and Coal Chemicals
  Institute
1255 Twenty-third Street, NW
Washington, DC  20037

Dear Mr. Ekfelt:

     Jeff Denit and I appreciated the opportunity to meet with
you on June 3, 1987, to discuss the Agency's study to determine
whether additional residual streams from by-product coke plants
and coal tar refineries should be listed as hazardous wastes
under RCRA.  This meeting helped us understand the concerns of
ACCCI members about the study; we hope that it clarified the
objectives of EPA's study of the coke industry.  This letter pro-
vides additional information to address the questions and concerns
that were raised by ACCCI in your meeting with Ed Abrams and
Dennis Wallace on May 14 and your May 26 letter to Mr. Abrams.
The responses below are organized to be consistent with your
letter.

     la.  To date, "trigger" levels for specific constituents pre-
          sent in coke wastes have not been established.  When
          established, these "trigger" levels will be health-based,
          not technology-based, and will be determined by first
          developing exposure limits for human consumption via
          drinking water and inhalation.  Next, the exposure
          limits will be used to calculate leachate and air
          emission concentrations using models developed by the
          Agency that predict transport through ground water or
          dispersion through air.  Finally, models that predict
          rate of constituent release from the waste will be used
          to calculate the regulatory levels in the residual stream.

     Ib.  The term "primarily aqueous", as used in Mr. Wallace's
          letter to Mr. Eagle, referred to waste water streams.
          Specific examples include waste ammonia liquor, waste
          waters from direct contact final coolers and light oil
          recovery operations, and tax refinery waste waters.
          The Agency has not established specific limits for solids
          content, organics content, or percent water to define
          these streams; they essentially are the streams that
          are commonly defined by the industry as waste waters.
          The leachate procedure that will be used for the streams

-------
                          -2-
     is the same TCLP procedure that will be used for all
     streams.   The TCLP procedure is defined in Appendix I
     to 40 CFR Part 268.  (See 51 FR 40643 for a definition
     of the procedure.) For residuals that have less than
     0.5 percent solids (a condition that we assume will
     hold for  most waste waters), the residual stream is the
     leachate  per that procedure.

2.    Any waste water discharges that are point source dis-
     charges under Section 402 of the Clean Water Act are
     excluded  from the definition of solid waste (and con-
     sequently are not hazardous wastes) per 40 CFR Part
     261.4(a)(2).  Further,  persuant to 40 CFR Part 264.1
     (g)(2), the requirements of Part 264 do not apply to
     the owner or operator of a wastewater treatment unit
     as defined in 40 CFR Part 261.10.   Among other require-
     ments, Part 261.10 defines waste water treatment unit
     as a device which is Part of a waste water treatment
     facility which is subject ot regulation under either
     Section 402 or 307(b) of the Clean Water Act; and meets
     the definition of tank (also defined in Section 261.10.),
     Thus, tanks may meet the criteria for the exclusion,
     but the exclusion would not apply to surface impound-
     ments.  As you are aware, some coke plant wastewaters
     are treated in surface impoundments rather than tanks;
     therefore, OSW is obligated to examine the need for
     regulating these waste streams and treatment units
     under RCRA.  The samples that we are collecting are
     necessary to determine the need to regulate these
     streams.

3.    The decisions related to listing additional coke plant
     residuals as hazardous wastes will be based on the
     criteria established in 40 CFR Part 261.11.  These
     criteria are based on the potential hazard posed by
     the wastes and the potential for mismanagement of the
     waste and, as such, are not related directly to waste
     minimization concerns.

          The listing of these wastes probably will not
     require major changes in the recycling and recovery
     practices that are used by many coke plants.  The pro-
     posed rule for burning waste in boilers and industrial
     furnances (see 52 FR 17019), May 6, 1987), specifies
     that the coke and coal tar produced when tar decanter
     sludge (K035) is used as a feedstock are classified as
     products not wastes.  The rationale for this proposal
     was that the residual and the normal feedstock or
     product have common constituents and that the residual
     streams and products are associated with the same

-------
                               -3-
          process.  Based on our understanding of the residual
          streams that we are examining and the current recylcing
          practices for those streams (use as a feedstock in the
          coke ovens or combination with tar in the decanter ) ,
          these practices are likely to be deemed acceptable
          under the rationale established for the K035 stream.

     4.   The "trigger" levels that will be established under  this
          listing/relisting study will not define technology-based
          limits to whcih residuals must be treated; they will be
          used to determine whether a waste stream is a "listed
          waste."  When a waste stream has constituents at or
          below the "trigger" levels, or if it is treated to reduce
          constituents to those levels,  it will cease to be a
          hazardous waste, unless it exhibits one of the hazardous
          character isitics defined in 40 CFR 261.21-24.  If the
          residual stream has constituent concentrations above
          the "trigger" level, it will be a hazardous waste and
          must be treated, stored, and disposed in a manner that
          complies with the requirements of 40 CFR Parts 262
          through 266 and 270.

     5.   As a part of this study, detailed information on waste
          management practices has been requested from most coke
          plant and taz refinery operators.  These data will be
          compiled and summarized in the background documents  that
          form the basis for the listing decision.  Based on the
          recent proposal related to tar decanter sludge that was
          described above, we anticipate that the information
          presented in these background documents will enable the
          Agency to make sound judgements on environmentally
          acceptable management practices, as well as the potential
          for a given waste to be improperly managed.

     I hope that these responses have addressed the concerns that
you raised in your May 26 letter.  If you have questions about
the responses please call me at (202) 382-4769.
                                   Sincerely,

Dear M». Schiffmant

     This is in response to your letter of June 10, 1987, in
which you requested our interpretation oa several issues involving
electroplating rinsewatars.  Specifically, you requested confirmation
of your conclusions drawn as a result of your teleafcoae converse*
tions with Hz. David Topping, of ay staff.  IB addition, you
requested our answers to five specific questions relatimg to the
hazardous waste/non-hasardous waste status of used iom exchange
resins that were used to treat electroplating rinsewaters.

     First, X would like to respond to the two queetions you
discussed with Mr. David Topping*  In particular, I agzee with
your conclusions thatt  1) rinsewatezs froa electroplating opera-'
tions were not meant to be included in the FOO9 listing (spent
stripping and cleaning oath solutions froa electroplating opera-
tions where cyanides are used in the process), and 2) residual
droplsts of stripping, cleaning, ox electroplating solutions
present on the aetal would not aaJce the rinsewaters hazardous by
the * mixture rule* when the aetal parts axe rinsed off.  In the
first case, rinsewaters axe not considered spent stripping or
cleaning bath solutions; ia the second case, trace amounts of
plating bath solutions that are carried over to rinse tanks are
not coneidexed to be a solid waste mixing with another solid
waste.  TaejM aatexiala are ia use and axe not wastes until they
axe spent apt xeaoved fxoa the process.  The remaining questions
will be inejwered in the saae order that they are presented in your
letteri

     1.    Tour fixst question asks "can a wastewatex treatment
           system which only is treating a non-hasaxdous electro-
           plating waste (such as rinsewaters) produce an FO06
           listed hazardous waste?*  The answer to this question
           is yesi the sludge froa the treataent of electroplating
           wastewatex contains toxic metals at concentration many
           tiaee higher than their conoemtration in the wastewatexs
           themselves.  It should also be noted that although
           electroplating rinsewaters axe not specifically listed

-------
           ia 40 CFR 261 Subpart D, they aay exhibit a hazardous
           waste characteristic  (EP toxicity) undex 40 CFR 261
           Subpazt C fox cextain toxic aatals.

     2.    Your ••cond question asks  "would an ion exchange
           canister which has been used to capture aetals and
           cyanide from non-hazardous «l«ctxopiating rinsewatexs
           only, be considered to contain wastewatax treatment
           sludges fxoa electroplating operations (EPA Hazardous
           Wast* Mo. F006)?"  The answer to this question also is
           yes.  Section 260.10 of 40 CFR dafines sludges as "any
           solid* seal-solid, ox liquid waste generated fro* a
           aunicpal, coaaexcial, ox industxial wastewater txeataent
           plant, watex supply treatment plant, ox effluent fxoa
           a wastewatex treatment plant."  Thus, any xesiduals
           genexated fxoa txeataent of wastewatexs fxoa electro-
           plating operations fox pollution control would be
           considered an FOO6 listed waste.

     3.    Youx third question asks "is the ion exchange xesxn,
           which is siailar in function to activated caxbon (i.e«,
           used to reaove pollutants fxoa wastewatexs), considqre^
           a 'sludge* in this situation?  Once again, the answer
           is yes fox the saae reason given above.

     4.    Youx fourth question asks "do xinsewatexs fxoa electro-
           plating operations fall within the scope of any listed
           hazardous wastes?"  The answex to this question is no;
           electroplating xinsewatexs axe not a listed hazardous
           waste undex 40 CFR 261, Subpaxt D.  However, as I
           indicated eaxliex, electroplating xinsewatexs aay
           exhibit a hazardous waste chaxactexlstic undex 40 CFR
           261, Subpart C.

     5*    Youx fifth question asks "does the 'aixture rule1
           apply to xinsewatexs froa electroplating operations due
           to the presence Of 'residual droplets1 of stripping,
           cleaning, or electroplating solutions?"  This question
           was aaawered previously.

     If yoo have further questions relating to this subject,
please tmml free to call MX. Edwin F. Abraas at (202) 382-47u7.

Dear Mr. Senna:

    This is in response to your letter of September 25, 1987,
concerning the regulatory status of your fragrance ingredients.
Based on the information you provided and the subsequent phone
conversation with our consultant, Geo/Resource Consultants, Inc.,
EPA»s understanding of the waste generation process is that
Acetone, ethyl acetate, and xylene solvents are periodically used
to clean out the reactor vessel.  The spent solvents generated
from that cleaning operation are drummed and sent off site for
proper management as F003 wastes.  A light coating or residue
consisting of fragrance oils and trace amounts of solvent remains
on the walls of the vessel.  IFF then washes the vessel out with
soap and water.  This waste washwater carrying the oil and
solvent residue then flows to an oil/water separator for
treatment.

    Based on this scenario, the Agency's interpretation is that
the solvent-contaminated washwater is not within the scope of  the
Hazardous Waste No. F003 listing for spent nonhalogenated sol-
vent.  The subject waste stream is generated from the washout of
a reactor vessel containing residues of solvent and fragrance
oils.  Therefore, the waste is not a spent solvent, but a process
wastewater contaminated with solvent constituents.  This waste is
very different from a solvent stream that has been used and  as a
result of contamination can no longer be used as a solvent
without furt&er processing (see section 261.2(cHi) and 50 Efi
53316).  It is not the Agency's intent to regulate water from
washout of a reactor vessel as F003.

-------
                                -2-


    If the washwater sent to the oil/water separator is ignit-
able, it would be classified as a D001 hazardous waste, and would
remain such for as long as it exhibits the ignitabil&y charac-
teristic.  According to 40 CFR Section 261.3(c) and (d), any
residues resulting from treatment of D001 are hazardous wastes
only if they continue to exhibit a characteristic found under 40
CFR, Part 261, Subpart C.

Michael Petrusfca of my staff at  (202) 382-7729.

Dear Mr. Gere:

    I recently received your letter and accompanying information
about a patented process for sewage sludge treatment which STONIM-
PEX, Incorporated would like to market in the United States.  I
appreciate receiving the information.  However, the Agency is not
in a position to endorse or support specific processes.

    While this may not be a problem, you should also be aware, that
residuals generated as a result of your process must be evaluated
against existing requirements.  Specifically, you must determine if
the residuals are characteristic hazardous waste prior to disposal
(see 40 CFR 261.11, 260 and 261 enclosed).  This determination can
be made by testing the residuals or applying knowledge of the
hazard characteristic of the waste in light of the materials or the
processes used.

    Additional requirements for the use and disposal of sewage
sludge are under development under the Clean Water Act.  These may
require you to test sewage sludge residuals prior to use and
disposal.  Please contact Mr, Alan Rubin  (202) 475-7311 of the
Office of Water concerning current and future requirements.

    Thank you for your interest in solid waste management.  If I
can be of further assistance to you, please contact me.

THROUGH:  Alec McBride, Chief
          Technical Assessment Branda
TO:
Carolyn Bosserman, Regulatory Analyst
SAIC
    In response to your letter dated March  14,  1988,  I
recommended the health-based level of 0.7 mg/L  for "free11
cyanide since this is based upon the Agency verified  reference
dose (vRfD) . (Please note, all vRfDs and unverified RfDs are
health-based numbers.)  It is the Office of Solid Waste's policy
to use MCLs if one exists.  If an MCL does  not  exist, then the
full value of the corresponding drinking water  concentration
limit based on the vRfD is used.

    In addition to the vRfD for "free11  cyanide,  there are
numerous other forms of cyanide for which there are vRfDs.
These are as follows:

 Most of the verified cyanide numbers, except for barium cyanide
and copper cyanide are based on the Howard and Hanzal study
which measured the effects of HCN-fumigated-feed on rats for two
years.  The differences in the numbers reflect adjustments for
the molecular weights of the metals or salts.  The barium
cyanide number is based on a barium study.  The copper cyanide
number is based upon the copper cyanide study sponsored by OSW.
The RfD workgroup did not reject the copper cyanide study, but
merely deemed it applicable only for copper cyanide.  A separate
study of potassium silver cyanide, also sponsored by OSW, was
presented at the same workgroup meeting but was rejected for
technical reasons.  Again had this study been accepted it would
have been appropriate only for development of a potassium silver
cyanide number.  In studies such as these, the metal
concentrations are such that they are believed to be the driving
force in the toxic effects observed.  Thus, such studies are
only applicable for development of reference doses for those
specific chemicals.  All of the health-based cyanide limits are
chronic, lifetime reference doses.

    With regard to the health advisory used in setting the
Office of Drinking Water's advisory level of 0.154 mg/L, this
too was based upon the Howard and Hanzal study.  Please note
that the Office of Drinking Water's procedure is to take 20
percent of a drinking water equivalence level, which is
developed using the same procedure used to develop a drinking
water concentration limit, in lieu of a site-specific exposure
assessment.  The Variance Section uses the VHS model to estimate
exposure.  Further note that health advisory numbers are not
enforceable standards, they are advisory limits for specific
exposure durations, in this case, lifetime.  Other limits
(including one- and ten-day health advisories) address acute and
less-than-lifetime expsore durations.

    Perhaps when referring to a cyanide number, the particular
compound should be stated, otherwise it will be assumed to be
for "free" cyanide, etc.  Again, the "free" cyanide vRfD of 0.7
mg/L is peer reviewed by the RfD workgroup and verified by them.

    I hope I have explained the apparent anomalies in the
cyanide Units.  For your information, I have attached the IRIS
cover sheets for all the verified cyanide numbers.  These are
difficult concepts.  If I can be of further assistance please
call me at 475-6726.

SUBJECT:  California Authorization - Evaluation of the Waste
          Evaluation Test

FROM:     Sylvia K. Lowrance,  Director
          Office of Solid Waste

TO:       Jeff Zelikson, Director
          Toxics and Waste Management Division, Region IX

    This memorandum is in response to your March 23, 1988
memorandum requesting a determination as to the technical
adequacy of California's Waste Extraction Test (WET) for
testing wastes to determine whether they meet the toxicity
characteristic.  Based on the description of the test and the
results you have provided, we believe that, for any waste
matrix, the WET will extract at least as much of each inorganic
constituent as the EPA Extraction Procedure (EP)  test.  Also,
since this action is an authorization issue, the WET does not
need to go through the Part 260.21 petition process for equiva-
lency.

    As you are aware, our Office of General Counsel (OGC) has
some concerns regarding the issue of possible Federal
enforcement of regulations based on the WET.  Currently, OGC is
of the opinion that regulations utilizing the WET are broader  in
scope  (cover more waste) rather than more stringent (tighter
control of covered wastes) than regulations utilizing the EP.
These concerns affect the overall authorization, and they still
need to be resolved.

    Please contact David Friedman (FTS 382-4761) of my staff if
you have any questions on the technical evaluation of the WET  or
Josh Sarnoff  (FTS 382-7706) of OGC if you have any questions on
the legal review.

-------
    If the washwater sent to the oil/water separator is ignit-
abie, it would be classified as a D001 hazardous waste, and would
remain such for as long as it exhibits the ignitabil&y charac-
teristic.  According to 40 CFR Section 261.3(c) and (d), any
residues resulting from treatment of D001 are hazardous wastes
only if they continue to exhibit a characteristic found under 40
CFR, Part 261, Subpart C.

    If you have further questions in this area, please contact
Michael Petruska of my staff at (202) 382-7729.

                                       Sincerely,

     As you may be aware, California  is  in  the  process of amending
its hazardous waste management statutes  and regulations for  the
purpose of obtaining authorization to implement the RCRA program.
California would like to retain its Waste Extraction Test (WET)
for testing characteristic waste rather  than adopting EPA's  EP
Toxicity Test.

     At this time we are requesting an official written determination
from your office as to  the technical  adequacy of the WET.  We
requested this  information previously and understand that David
Freidman of the Technical Methods Section did some research  on
this issue.

     Based on previous discussions between  Headquarters and
Regional staff/ we believe there is agreement between the Region
and Headquarters that the WET is at least as stringent as the  EP
Toxicity Test required  under RCRA and therefore, meets the
authorization requirement that the State program be equivalent to
or more stringent than  RCRA.

     California's regulation development schedule requires  that
we give them a  final decision on this issue within the next  few
weeks.  For this reason, if we have not  received a response  by
April 30, we will inform California that the WET is as stringent
as the EP Toxicity Test and, therefore,  will be acceptable  for
the purposes of authorization.

HAZARDOUS MATERIALS LABORATORY
CALIFORNIA DEPARTMENT OP HEALTH SERVICES


AN EVALUATION OF IKE WASTE EXTRACTION TEST  (WET) FOR HAZARDOUS MASTS
IDENTIFICATION
I.     The Problem

      As part  of  the  RCRA authorization process,  the  California
      .Department of Health Services is evaluating its criteria for
      hazardous waste characterization vis-a-vis the EPA system.  One
      issue which has arisen is whether  the California Waste Extraction
      Test (WET)  is at  least as  stringent  as the EPA  Extraction
      Procedure (EP) for the purpose o'f determining the extractable
      inorganic constituents.

      A related  issue is the comparison  of the California system and the
      Federal system for  organic compounds.  That issue  will be
      addressed in a  future document  separately  from the issue of
      inorganic substances.

II.    Comparison of the two  Extraction Tests

      The  WET procedure is desribed completely in Section 66700 of the
      California Administrative Code.  Title  22.  A copy of that section
      is included in Attachment A.  The EP  is d~esrribed in 40CFR Part
      261,  Appendix II.  and  a  copy  is  included as  Attachment  B.
      Briefly, both of these procedures  are batch extraction tests.  The
      principal difference between  the two  tests is  the choice of
      extraction solution.   The EP uses  an acetic  acid extraction
      solution, while the  WET uses a  0.2 M citrate  buffer solution.
      Citrate is recognized as a much  stronger chelating agent  thar.
      acetate.  The stability constants  for  acetate and  citrate
      complexes  of  selected metal ions are listed in Table 1.

         Table  1 - Stability of Metal Complexes (Kragten. 1976)

      Metal Ion      Citrate Complex         Acetate Complex

      Chromivjn (III)           7.69                    1.80

      Mercury (II)            10.90                    5.30

           (II)                6.30                    2.20
      As shown in Table 1. the citrate is predicted to be a stronger
      chelating  agent  than acetate.

III.   Comparative Performance of  the WET and EP

      The  prediction  of  greater  stringency of  the  WET has  been

-------
      demonstrated over several years of testing a diverse collection of
      solid wastes.  Some examples of documented studies are given
      below.

      A.  The Oak Ridge National Laboratory (OFML) Leaching Study

         The California Waste Management Board sponsored a study of
         leaching tests,  which  was  conducted at  ORNL under  the
         management of C. W.  Francis.  The study  included the WET.  the
         EP, and two leaching rests which were being considered to
         replace the EP.  These  tests were used in the development of
         the TCLP.  One conclusion of the ORNL Report  was "Generally
         speaking, concentrations of all  the  trace metals  were higher
         in the WET extracts than in other leach extracts...(Francis.
         1984)"  This was the result whether extracts  were  analyzed by
         atomic absorption  (AA) or inductively coupled plasma (ICPi
         spectroscopy.  indicating that- the differences  were due to the
         extraction method.  A copy of  data from the ORNL study is
         included as Attachment  C.

      B. Battelle Leaching Study

         As part of the evaluation of leaching tests for hazardous
         waste identification,   the Battelle  Columbus  Laboratory
         conducted a comparison of leaching tests on several solid
         wastes. including_aqueous sludges, organic chemical wastes,
         and inorganic solids. A conclusion of the study was:  "Citrate
         buffer was often much more aggressive th-n. acetate buffer for
         leaching metals (Warner, 1981)."  This was  in spite of the
         fact that the highest concentration of ci-rate buffer used was
         less than that required in the current WET.

      C.  Experience in Hazardous Waste Identification

         The experience of the DHS over several years has been that the
         WET  is consistently at  least  as  stringent as  the EP for
         hazardous waste identification.  As an example,  lead  smelting
         slag from the Asarco hazardous waste site in Selby. California
         was tested by both  the EP and the WET.   Although  the site has
         a  documented  source of arsenic  contamination  in the
         groundwater, the EP identified it as nonhazardous by the EP
         criterion, whereas  it easily exceeded hazardous waste criteria
         by the  WET.   This situation is typical of  EP  and WET
         comparisons (DHS HML files).

IV.    Quality of Data Generated by  the WET

      The WET  and the EP have both  several  years of  uss in the
      commercial and industrial laboratory community.  The formalization
      of orocedures in regulation has eliminated  inconsistency problems
      which formerly existed.  Unlike the EP. the WET is included in a
      mandated Hazardous Waste LMoratory  Certification Program which is
      conducted  by DHS.   This program includes requirements  for
      personnel, equipment, analytical methods, quality assurance pli

-------
      and performance  testing.   Interlaboratory testing which has been
      conducted to date indicates that the precision of the WET is as
      good *».  or  better  than the precision of  the  corresponding
      analytical procedures and is in general far  better  than the
      precisian of sampling procedures ( Dffi HML files).
V.   Stannary
      The experience  of DHS.  federal laboratories and  commercial
      laboratories is that  the WET is at least as stringent as the SP
      for the purpose of identifying hazarous wastes by extractable
      metals. The DHS certification program will help to assure that
      the quality of data  generated  by the MET is adequate for the
      California Hazardous Waste Management Program.

  (e) The WET extraction solution shall consist of 0.2 M sodium citrate at pH
5.0  ± 0.1, which is prepared by titrating an appropriate amount of analytical
grade citric acid in deionized water with 4.0 N NaOH. except that the extraction
solution far the determination of chromium (VI) shall consist of deiomzed
water.
  (f) The ertiaction procedure shall be as follows:
  (1) Fifty fracas of sample, or less if it is a type ii sample prepared pursuant
to subsection  (c) (2), obtained pursuant to subsection (c) or (d) of this section
shall be placed in a dean polyethylene or glass container designated the Treat-
ment, capable of physically withstanding  the extraction procedure and which
was rinsed previously with, in succession, an aqueous 1:1 ratio by volume nitric
acid solution and deionized water. If the extract will be analyzed for any of the
organic substances listed in Section 666W(c), a glass container shall be used.
Furthermore, a container of the same size, shape and material shall be used for
an extraction  designated as the Blank, which shall be carried
procedure as  me Treatment, but without addition of the sample.
  (2) Five hundred millihten of extraction solution, or less if the waste sam
is a type ii sample prepared pursuant to subsection (c) (2) shall be added to
Treatment and Blank containers, which shall be then fitted with covered air
scrubbers extended  well into the extraction solutions and flushed vigorously
with nitrogen gas for 15 minutes so as to remove and exclude atmospheric
oxygen from  the extraction medium If the sample is to be analyzed for any
volatile substance, such as thchloroethylene, the sample shall W added  after
detention with nitrogen to avoid volatilization loss. After deaer^tion the con-
tainers shall be quickly sealed with tightly fitting caps and agitated, using a  table
shaker, an overhead stirrer or a rotary extractor, operated at a speed whkb shall
maintain the sample in a state of vigorously agitated suspension.  Repaired
equipment is described in test method 1310 in Test Methods for Evaluating
SoficTWaste, Physical/Chemical Methods", SW446,2nd edition. UJ5. Environ-
mental Protection Agency, 1982. The temperature during the extraction shall
be maintained between 20 and 40 degrees centigrade. After 48 hours of extract-
ing, the contents of me Treatment and Blank containers shall be either filtered
directly or centhruged and then filtered Filtering shall be through a »••*«"«
porosity prefiHer and then through a 0.45 micron membrane niter, using a.
dean, duck-waDed suction flask.  For coarser solids, prefihration shall not be
	asary. Pressure filtration shall be an optional alternative to vacuum fihra-
    . If the extracts are first centrifuged, glass or polyethylene bottles shall be
                  for extraction. For very fine foods, t'*ntii*t^gmg at
        i X C may be nec«tary. After centrirugahon, the liquids shall be
        jrefflterad if necessary, and then passed through a 0.45 micron mem-
brane fitter. AO fitters shall be of low and identified extractabte heavy metals,

   (3) If the filtered extracts are to he analyzed only for the metal elements
listed in Section 8MW(b). the filtered extracts from the Treatment and Blank
shall be transferred to ckan polyethylene bottles and acidified with nitric acid
to five peicent by volume acid content soon after each eiliatt is filtered. For
those wastes or waste materials classified under subsection (c) (2), the Treat-
ment shall be the Initial Filtrate combined with the extract generated by the
WET extraction of the initially separated solids. Similarly the  Blank in this
instance shall be the filtrate generated by the WET Blank accompanying the
initially separated solids, to which is subsequently added a volume of deionized

lowed prior to acidificanon of Treatment tod Blank solutions with nitric acid
to five percent (by volume)  acid content. The bottle dull then be stored at
room temperature or frozen. If the extracts are also to be analyzed for me
organic suDftaaces listed in Section 66699 (c) , or for me organic substances only,
the filtered extracts shall be transferred to dean gust bottles. If the extracts are
to be analyzed for fluoride,  they shall be transferred to clean polyethylene
bottles. These extracts, containing organic substances or fluoride, shall not be
acidified, but shall be frozen soon after each extract is obtained and held frozen
until the day of analysis, unless the extracts are analyzed within 24 hours.
   (g) Sample analysis and data treatment shall be at follows:
   (I) Each of the filtered extracts from the Treatment and Blank extractions
shaO have been acidified  to five percent by volume nitric acid, and stored at
room temperature or frozen in polyethylene bottles or kept frozen  without
addition of acid in fiaa bottles until the day of analysis, as prescribed. Each of
the extracts shall be thoroughly mixed just prior to being individually analyzed
for the subctances listed in Section 66699 in  order to determine whether the
etti actable concentration (EC) in the waste or other material exceeds the
STLC for any of the substances listed. The extracts shall be analyzed according
to the procedures identified in Sections 66700(b) (2), (b) (3) and (b) (4).
   ( J) The net EC of a substance in the Treatment sample which is  Ested in
Section 66699 shaD be calculated and reported as milligrams per liter of sample
(mg/1). This value is derived after subtracting the concentration of  the sub-
stance in the appropriate Blank extract from that concentration determined in
the Treatment extract

Ms. Robyn-Marie  Lyon
McDermott, Will  and  Emery
2049 Century  Park East
Suite 600
Los Angeles,  CA  90067-3108

Dear Ms. Lyon:

    I am responding  to your letter  dated  September 7,1988,  to Bob-
Dellinger which  requests  confirmation of  a hazardous waste
interpretation of a  waste stream  generated by one of your
clients.  Specifically, your client uses  a bronze plating process
which plates  a copper-tin alloy on  carbon steel wire.  No
electrodes or electrolysis are employed in the process.

    You have  spoken  with  Mr. David  Topping of my  staff  regarding
this process.  As Mr. Topping has informed you, this process is
characterized as "immersion plating", rather than electroplating
and, therefore,  treatment of this process1 wastewater will not
generate F006 unless electroplating rinse waters  are mixed with
the immersion plating wastewaters prior to treatment.

    You should advise your client that  any wastes generated by
the immersion plating process should be evaluated prior to
disposal to determine whether they  exhibit any of the hazardous
waste characteristics (i.e.. ignitability, corrosivity,
reactivity, or extraction procedure (EP)  toxicity - see 40 CFR
261.21-24).

    Also, you should be aware that  the  states may have  a
regulatory program more stringent than  the Federal program  (i.e..
the State hazardous  waste program may consider these wastes as
hazardous under  State law).  Therefore, you  will  have to contact
the various States where  your clients are located to determine
how these wastes should be handled  under  State law.

Mr. Richard Torrito
Assistant General Counsel
Continental Can Company, Inc.
P.O. Box 5410
Norwalk, Connecticut  06856

Dear Mr. Torrito:

     It was a pleasure meeting, with you on December 22, 1988 to
discuss the regulatory status of wastewater treatment sludges
from the zirconium phosphating of aluminum cans which are
generated and managed by Continental Can.

     As we discussed at that meeting wastewater treatment sludges
generated by Continental Can are within the scope of the listing
for wastewater treatment sludges from the chemical conversion
coating of aluminum.  Based on the process chemistry and
information received by the Agency, we do not believe that these
wastes contain or form Appendix VIII constituents in hazardous
concentrations.  Therefore, it is the Agency's belief that
wastewater treatment sludges from this process should not be
classified as hazardous waste and that Continental Can and other
can makers employing the same process and chemical constituents
should be granted regulatory relief from managing their sludges
as hazardous wastes as quickly as possible.

     The Agency believes that the best way to accomplish this is
to modify the F019 listing to exclude the zirconium phosphating
of aluminum cans process through an expedited rulemaking.  One
issue you raised during the meeting was whether the modification
to the listing would retroactively apply to previously generated
wastes.  According to our Office of General Counsel, the listing
modification would be retroactive (i.e., once the F019 listing
modification is final, previously generated wastes would not be
classified as F019).
        This has been retyped from the original document,

-------
     I want to assure you that making the modification discussed
with you is a high priority within the Office of Solid Waste.  It
is already underway and will be carried out as quickly as
possible.  We will keep you informed.

                                   Sincerely,
                                   Sylvia K. Lowrance

MEMORANDUM

SUBJECT:  Fluff Analyses

FROM:     Alec McBride, Chief
          Technical Assessment Branch, OSW

TO:       Cynthia Stroup, Chief
          Design and Development Branch, OTS

    The purpose of this memorandum is to clarify some of the
details of the analytical procedures that we understand will be
used in the fluff sampling and analysis project.  We appreciate
the efforts that your office has put into dealing with the
difficulties encountered in collecting and analyzing the fluff
samples.

    As you know, OSW has asked for analyses of lead and cadmium
in both the total fluff samples and the Extraction Procedure
(EP) extracts from those samples.  Both sets of analyses should
be conducted on the samples after they have undergone appro-
priate size reduction steps to meet the EP requirements.  One
thing I have not brought up in our discussions but would like to
mention now is that the EP does not require size reduction of
materials whose ratio of surface area to weight is greater than
3.1 cm2/g.  Materials such as pieces of fabric or wire could
likely be put directly into the extraction bottle without being
reduced in size to pass through the 9.5 mm sieve.

    Please call me on 382-4761 if you have any questions on the
EP requirements (although MRI should be familiar with them).
Also, we would like to take care of our share of the costs of
the project as soon as you have your final estimates.  Thanks
again for all your help.

Mr. Richard S. Leonard
Quality Control Coordinator

Santa Rosa, CA 95401

Dear Mr. Leonard:

      I am writing in response to your letter of February 9, 1989
requesting guidance on what analytes to look for when performing
RCRA analyses.

      One selects the list of target analytes based on the
regulatory purpose for which the analysis is being performed.
For example, if one is a land disposal facility which is required
to monitor its ground water, then one analyzes the ground water
for those analytes listed in Appendix IX of 40 CFR Part 264.  On
the other hand, if the reason for testing is to determine if the
waste is a hazardous waste by reason of Extraction Procedure
Toxicity, then one only needs to analyze the Method 1310 extract
for the 8 metals and 6 organic compounds listed in 40 CFR Part
261.24.  Generally, the analyses a facility must perform are
described in its permit and, especially the Waste Analysis Plan.

      I can understand how the various lists and analytes
described in Test Methods for Evaluating Solid Waste (SW-846) can
be confusing.  SW-846 is a compilation of methods designed to
cover all testing one might need to do to comply with RCRA data
gathering needs.  It contains testing methods for complying with
all aspects of the RCRA regulations and a method may be indicated
as being approved for determination of analytes which might not
need to b* determined in one's particular situation.

      If you have any other questions on the RCRA regulations, I
suggest that: you contact the RCRA toll free hotline at
800-424-9346.

                                     Sincerely yours,
                                     aavid Friedmanf

MEMORANDUM

SUBJECT:  Antarctica Waste Disposal  Practices

FROM:     Sylvia K. Lowrance, Director
          Office of Solid Waste

TO:       Brenda Sue Thornton
          Office of International Activities


     The purpose of this memorandum  is  to provide  comments  from
the Office of Solid Waste (OSW) on the  Scientific  Committee on
Antarctic Research  (SCAR) Panel of Experts recommendations
concerning waste disposal practices  in  Antarctica.  OSW agrees
that the present Code  of Conduct provisions concerning  waste
disposal are inadequate in some respects  and  need  updating.   In
particular, the Code:

     o    categorizes  wastes by disposal  method, rather than by
          waste characteristics and  the degree  of  hazard they
          pose to the  environment;

     o    allows land  and ocean dumping of untreated  sewage,
          solid and even hazardous waste;

     o    allows open  burning and incineration  without  air
          emission controls.

     OSW also generally agrees with  the SCAR  Panel of Experts
recommendations, with  some comments  and suggestions for changes,
as follow:

     o    In general,  the language of  the recommendations  and the
          present Code is too qualified and conditional (e.g.,
          vague qualifiers like  "discourage the use of,"  "where
          appropriate," and  "take  into account").   Additionally,
          waste disposal standards should be  incorporated under
          the Treaty as a new Agreed Measure  to make them more
          binding.

     o    Recommendation #3:  To some  extent, wastes continue to
          be categorized by  disposal method,  rather than by
          characteristics and degree of hazard they pose to the
          environment.  We believe that wastes should be
          categorized  in the following manner:

-------
          Waste water containing sewage,  domestic waste,  and
          other organic waste with  BOD  and mineral nutrients,
          that will be discharged to  the  land,  ice, surface
          water, or ocean,  is one class of waste.  (This presently
          falls under class 1.)   Hazardous waste should not be
          mixed with waste  water.

          Wastes that exhibit hazardous characteristics,
          regardless of whether they  are  liquids or solids, or
          combustible or noncombustible,  are another  class of
          waste (hazardous  waste).   (This roughly  corresponds to
          class 2.)  Within this class, hazardous  waste may then
          be subdivided into combustibles, noncombustibles,
          liquids, and solids (2a,  2b,  2c, 2d).  They must be
          managed, handled, stored, transported, and  disposed of
          to prevent their  release  into the  environment.
          Hazardous waste should not  be mixed with waste  water  or
          nonhazardous solid waste.

          Solid wastes that do not  exhibit hazardous
          characteristics may then  be divided into the two
          categories of combustible and noncombustible (Groups  3
          and 4).

          Radioactive wastes (Group 5), already are a separate
          waste class, and  should not be  mixed with any other
          type of waste prior to removal  from Antarctica.

     o    Recommendation #4:  While waste management  and  disposal
          by each country should be designed to meet  that
          country's national standards, universal  minimum
          standards for Antarctic waste management are necessary
          in order to achieve uniform protection of the
          environment.  It seems inequitable and futile to have
          some countries achieving  high standards  at  considerable
          expense, while others, whose  national environmental
          standards are low, escape these costs and  contaminate
          the air, land, and water.  Some mechanism  also is
          necessary to make these universal  minimum  standards
          enforceable, such as incorporation under the Treaty as
          an Agreed Measure.

3.    In light of Recommendation 14, U.S.  waste disposal practices
     in Antarctica should conform to  standards found in 40 CFR.

          Hazardouswaste:   Processes should be designed to
          minimize the generation of hazardous waste.  Likewise,
          the purchase and import of  virgin materials that will
          become hazardous waste should be  minimized.  Hazardous
          waste that does not meet Best Demonstrated Available
          Technology  (BDAT) treatment standards cannot be land
          disposed  (as defined in the Land Disposal Restrictions
          Standards in 40 CFR 268)  .  If treated to BDAT  standards
          onsite  (For most hazardous waste,  properly conducted

-------
high temperature incineration often will achieve
BOAT.)/ the residual may then be disposed on or in the
land.  However, the land disposal unit must meet 40 CFR
264 design requirements, with "minimum technology" such
as double liners and a leachate collection system.
Note that studies should be conducted to assess the
efficacy and feasibility of "minimum technology
requirements" in the Antarctic.  Alternately (and pre-
ferably) , the treatment/incineration residuals should
be removed from  Antarctica.  Also, if incineration
does not achieve the BOAT standard, waste must be
removed from Antarctica.  Hazardous waste incinerators
must meet design and operation requirements specified
at 40 CFR 264.  Finally, hazardous waste subject to the
Land Disposal Restrictions should be stored and
accumulated only in tanks or containers prior to
treatment/incineration or removal, and only for up to
one year.  (40 CFR 268.50)

Solid waste:   Waste minimization, of both solid and
hazardous waste, should be emphasized in order to
reduce the volume disposed of.  Packaging materials
that will become refuse should be minimized at the time
of purchasing and supply.  Ideally, purchase of
plastics such as PVC, polyurethane, polystyrene should
be minimized if these materials cannot be recycled.
Materials should be recycled and recovered to the
maximum extent possible (e.g., silver recovered from
photographic waste).  Combustibles should be
incinerated separately from hazardous waste and only in
double-burning high temperature incinerators with air
emissions controls.  (See 40 CFR 240-257 for solid
waste management regulations.)

Waste water;   OSW believes that the Office of Water
should comment on waste water treatment and discharge
requirements.  Nonetheless, we raise the following
points for consideration and discussion:  At isolated
bases, treatment of waste water prior to discharge may
be difficult or impossible.  However, use of composting
toilets, both at bases and stations, is a possible
solution to sewage disposal.  At coastal stations,
primary treatment  (physical maceration) alone  is
inadequate; waste water needs biological treatment to
reduce BOO (with Rotating Biologicial Contactors  (RBC)
or equivalent) prior to discharge.  Untreated  sewage
should not be discharged to the ocean.  Despite the
relatively low population of Antarctica, significant
local impacts on the marine ecology could  occur  from
discharge of untreated waste water.  Furthermore,
because ice-free land is scarce and the ecosystem rare,
discharge to land  also could significantly impact this
ecosystem.  Additionally, hazardous waste  should  not  be
mixed with waste water.

-------
          Ocean dumping of solid or hazardous waste, or untreated
          waste water  (sewage) is prohibited in the U.S. (except
          for dredge and fill materials) and should be
          eliminated.

          Despite the logistic problems caused by the remote
          location of Antarctic stations and bases, waste
          disposal standards should not be compromised, either
          for U.S. activities or for other countries' activities
          This is especially true in Antarctica, where pristine
          ecosystems must be protected for their scientific
          value.  Protective waste disposal standards can be
          achieved in Antarctica, although costs may be greater
          than in other parts of the world.

     Please contact Dave Reeves at 382-4679 to discuss these
comments further.

Dear Mr. Greenberg:

     This letter is  intended as a follow-up to an Agency letter
of October 27, 1988,  which was in response to your written
inquiry of August 11, 1988.  In reviewing our letter, we
discovered that some  language was not included, due to a computer
error.  We would like to take this opportunity to correct this
omission, thereby avoiding any confusion.

     In our letter, we^ stated, "A residual generated from the
treatment, storage, or^ disposal of a characteristic hazardous
waste (or a waste that has been listed only because it exhibits a
characteristic, such  as F003) is a hazardous waste only if it
exhibits a characteristic."  This sentence should have stated, "A
residual generated from the treatment, storage, or disposal of a
characteristic hazardous waste (or a waste that has been listed
only because it exhibits a characteristic, such as F003), when
mixed with a solid waste, is a hazardous waste only if it
exhibits a characteristic."  However, we reiterate that treatment
of a characteristic hazardous waste or a non-hazardous solid
waste may generate a  lasted hazardous waste, such as the
electroplating wastewaters mentioned in our previous""letter.  In
that example, treatment of characteristic wastewaters generates a
sludge which is listed as F006, even if the treatment occur? off-
site from the generation of the wastewater.

     We apologize for any inconvenience this error may have
caused,   if you have  any further questions, please call the
RCRA/Superfund Hotline at 382-3000.

                                 Sincerely,

Dear Mr. Nash:

    This letter is written to inform you that your letter of
August 8, 1989, concerning the regulatory status under the
Resource Conservation and Recovery Act  (RCRA) of your system for
recycling/treating aerosol cans has been referred to Mr. Jeffrey
Zelikson, Director of the Toxics and Waste Management Division
in EPA's Region IX Office (San Francisco, California).

    EPA's current policy regarding the  regulatory status of
non-empty aerosol can puncturing, crushing or shredding is that
the appropriate EPA Regional office is  to make a determination
on a case-specific basis.  Although the December 30, 1980,
letter from Mr. Gary Dietrich indicates that such activity is
not RCRA-regulated treatment, subsequent evaluation by EPA has
determined that such activity may, indeed, meet the definition
of treatment found at 40 CFR 260.10 (i.e., such activity may, in
fact, change the physical or chemical composition of a hazardous
waste, or render such waste amenable for recovery).  However,
until EPA develops a final determination regarding such
activities, the Regional offices, or authorized State regulatory
agencies, will make such determinations on a case-specific
basis.

    Thank you for your interest in the  recycling of solid
wastes.  If you have any questions regarding your letter, you
should contact Mitch Kidwell, of my staff, at  (202) 475-8551.

                                  Sincerely,

Dear Mr. Collins:

    I am writing in response to our telephone conversation
concerning Method 1320, the  Multiple Extraction Procedure.
Method 1320 states that after the EP (Method 1310) is run on the
initial waste sample of 100 grams, the solid phase remaining
after filtration is reweighed and a synthetic acid rain solution
is added to the solid phase in a 20:1 ratio.  The sample is then
extracted and filtered.  After filtration, the remaining solid
is again reweighed and the extraction fluid is again added in a
ratio of 20:1, and so on through the remaining multiple
extractions.

    I had originally said that the synthetic acid rain
extraction fluid should be added in a 20:1 ratio based on the
sample's initial dry weight.  However, this approach does not
take into account what would really happen to the waste in a
landfill environment.  Method 1320 is trying to predict what
would happen to the waste when it is placed in a landfill and
subjected to rainfall over a long period of time.  The waste may
absorb water after contact with the acid rain or may lose weight
due to the percolation of the acid rain through the waste.  In
either case, the waste has been modified by the acid rain.
Therefore, in order to mimic this behavior in the laboratory,
the wet material that remains after each extraction with the
synthetic acid rain solution is the material that should be
weighed and used to calculate the 20:1 liquid to solid ratio.
The dry weight of the original waste sample of 100 grams should
not be used.

    If you have any questions with this, please give me a  call
at  (202) 475-6722.


                                  Sincerely yours,

Dear Mr. Steinwurtzel:

     This letter is in response to your letter of September 22,
1989, discussing the issue of waste testing procedures for blast
slag generated by lead recycling facilities.  I appreciate your
bringing this matter to our attention.  While this type of issue,
particularly in the enforcement context, is one in which the
Regional offices generally have the lead, I can give you some
idea of our thinking at Headquarters in response to your
concerns.

     With respect to the technical aspects of the proper
application of the Extraction Procedure (EP) Toxicity test, we at
EPA Headquarters are in agreement with the discussion presented
by Mr. James Scarbrough of our Region IV office in his
September 27, 1989, letter to you (copy enclosed).  Specifically,
we believe the sampling procedure used by the Secondary Lead
Smelters Association (SLSA) is inadequate because: 1*} the sample
is not taken from the actual waste material at the point of
generation and 2) the physical characteristics and chemical
composition of the sample are likely to be different from those
of the waste material.  Given the actual nature of the waste as
described in Mr. Scarbrough's letter, we also agree with his
conclusion that the structural integrity procedure and the
stirring procedure for agitation are not appropriate for this
type of waste.  Furthermore, we understand that the Region, in
consultation with EPA's National Enforcement Investigation
Center, has always taken these positions with respect to sampling
and analysis of smelter slag waste.

-------
     We recognize that your clients may be in the position of
having to defend against an enforcement action at this point.
However, I believe that if you look at Mr. Scarbrough's letter of
September 21, 1989, he indicates a willingness to attempt a
proper disposition of this matter without extensive and expensive
litigation.  I encourage you to explore this suggestion directly
with the Regional Office.

     Thank you for communicating your concerns to me.  If I can
provide any further clarification on the role of Headquarters on
this type of issue, please feel free to contact me.
                                        Sincerely,

Dear Dr. Diehn:

     This  is in response to your letter dated March 27,  1990,
requesting an interpretation  regarding the regulatory  status of
paint spray booth air filters  containing toluene and xylene.

     It is my understanding that your client's  painting process
generates  an air filter which  becomes contaminated by  overspray
that is inherent in the paint  spraying process.   This  filter is
replaced when it becomes "spent."  Your letter  also indicates
that your  client's paint contains the solvents  toluene and xylene
as ingredients  in the paint formulation.   Your  letter  does not
indicate that these solvents  (or any other solvents listed in 40
CFR 261.31) are utilized for cleaning purposes,  nor that your
client's air filters capture overspray generated during paint
spray booth cleaning operations.

     Based on the information  provided, it appears that your
client is  not generating spent air  filters that contain a
hazardous  waste listed in 40 CFR 261.31.   Process wastes
containing solvents where the  solvent is used as an ingredient  in
the formulation of a commercial  chemical product, do not fall
within the scope of the spent  solvent listings.   Additionally,
the products themselves do not meet the listings.  This point is
stated in  the preamble to several solvent rules (see 50 FR 53316,
51 FR 40606) as well as in the listing background document.
However, should a spent solvent  (i.e., a solvent that  can  no
longer be  used  for its intended  purpose without first  being
reclaimed) be mixed with the  filter, the resultant mixture is a
hazardous  waste pursuant to 40 CFR 261.3(a)(2)(iv).
                                                        frvtttd m RtcyeUd Paptr

-------
     Your letter does not provide enough information to determine
if your client's air filter would exhibit any of the four
characteristics of hazardous waste.  Each generator is
responsible for evaluating his individual waste stream to
determine if it meets a listing of hazardous waste in subpart D
of 40 CFR Part 261, or if it exhibits any characteristic of
hazardous waste identified in Subpart c of 40 CFR Part 261.
Furthermore, State and local regulatory agencies may have
regulations that are more stringent than those at the Federal
level.  Your client should contact the appropriate State agency
to determine what, if any, additional regulations may be
applicable.

Re:  Bias Correction on TCLP

Dear Mr. Paessun:

     We are pleased to respond to your concerns regarding the
application of bias correction for the TCLP.  This response will
supplement our initial responses to questions from your company
(communication with Mr. Marvin Stephens) and hopefully will cover
all of your concerns.

     The issue of bias correction was covered in the TC final
rule of March 29, 1990 (55 FR 11875).  A restatement of the
requirement to correct for bias and a description of the method
for bias correction was issued in the June 29, 1990 correction
notice  (55 FR 26993), to clarify the intent as well as procedure.

     We would also like to respond to your specific questions:

     1.  The TCLP method does indeed apply to both the Toxicity
     Characteristic program and the Land Disposal Restrictions
     program.  Any time the TCLP is required, any and all
     requirements within the procedure must be met.  It should be
     noted that the limits set in the Land Disposal Restrictions
     program were established based on data which was corrected
     for bias.

     2.  All TCLP analytical results are to be corrected for
     bias, including those which fall below the treatment
     standards.  This is indeed the intent of spike recovery.  In
     some cases the method (or laboratory/analyst) may
     underestimate the true concentration.  It is for that reason
     that it is critically important that the spike recovery
     correction factor be applied when the results are less than
     the treatment standards.

-------
     3.  Data collected before the mandatory date would not be
     subject to correction for analytical bias to comply with the
     toxicity characteristic ruling.  However, it should be noted
     that the facility may be liable for proper disposal of any
     waste which was improperly identified.  After September 25,
     any hazardous waste determinations should be based on the
     TCLP with bias correction.

     4.  If you wish to supply information on the impact of bias
     correction on generators of hazardous waste, I suggest you
     send this information to:

          Steve Cochran

          OS-331
          401 M Street

     I hope we have been responsive to your questions.   If you
need additional information on the Toxicity Characteristic Rule,
please contact Steve Cochran at 382-4769 or contact Jeanne
Hankins at 382-4761 for questions on bias correction.

SUBJECT:  Request for US EPA Headquarters Assistance in Selection
          of Non-US EPA Approved Methods for RCRA Subpart X Permits

FROM:     David Bussard

          Characterization and Assessment Division  (OS-330)

     This memo  is  in response to  the  request by Terry Anderson,
Chief of the RCRA  Implementation  Branch,  Region VIII, for Office
of  Solid  Waste   (OSW)   headquarters  guidance  on  appropriate
analytical  methods  for the  analysis  of  the  following eleven
compounds  (with  CAS  Nos,)r  in  air,  from  open  burning/open
detonation, for which no approved USEPA methods  apparently exist:

     Cyanogen chloride        (506-77-4)
     1,1-Diethylhydrazine     (616-40-0)
     1,1-Dimethylhydrazine      (57-14-7)
     1,2-Dimethylhydrazine    (540-73-8)
     Ethyleneimine            (151-56-4)
     Hydrazine                (301-01-2)
     Hydrogen cyanide           (74-90-8)
     Methylhydrazine            (60-34-4)
     Nitric oxide           (10102-43-9)
     Toluene diisocyanate     (584-44-9)
     o-Toluidine hydrochloride  (95-53-4)

United Technologies advocates the  use of Draeger tubes for these
analyses, while  Region VIII  advocates the  use  of supercritical
fluid chromatography (SFC).

     From our experience, OSW agrees with the Region VIII  position
that Draeger tubes are inappropriate for use in  this application,
because  they  are  prone  to  giving  false  negative  responses.
However, it is also our opinion that SFC is  inappropriate as well
for this application.  SFC is an unproved technique for

-------
environmental  analyses,  and  shows  little  promise  of  future
applicability,  particularly  for  the  above  list  of  compounds.
Therefore, SFC  has a low  priority in OSW's  methods development
program.

     Toluene  diisocyanate  and  o-toluidine  hydrochloride  (as  o-
toluidine) can be  determined  by SW-846 Method 8270.   They should
also be amenable to sample preparation by one of the methods listed
in  the "Compendium  of  Methods  for the  Determination of  Toxic
Organic  Compounds in  Ambient  Air",  EPA-600/4-84-041,  and  its
subsequent updates,  originally issued  in  April,  1984 by  EPA's
Atmospheric Research  and Exposure Assessment Laboratory  in Research
Triangle Park, North  Carolina. Methods for  nitric oxide and other
gases  in  air may  be available from the  Office of  Air Quality,
Planning and  Standards  (OAQPS)  in  Durham,  North Carolina.   OAQPS
has  published a  number of ambient air methods  in the  Federal
Register as a part of their regulations.

     Other  sources  of  applicable  methodology  for  analysis  or
monitoring  of   these   compounds   in  ambient  air  include  the
manufacturers  of  the   compounds  in  question  and   the  National
Institute  for  Occupational  Safety and  Health   (NIOSH).    The
manufacturers need to monitor the quality of their products through
assay methods, and also to  monitor air  exposure of their workers
to these compounds during the  course of the manufacturing process.
Exposure monitoring methodology is a specialty of NIOSH, and they
publish many volumes of analytical methods.  Manufacturers of the
compounds  of  concern should  be found  in  the  trade publication
"Chemical Sources", which is commonly used by chemical purchasers.

     If we can be  of further assistance,  please feel free to call
Barry Lesnik of my staff at FTS: 382-7459.

Mr. Michael C. Stroh
Trace Organics Supervisor
PDC Laboratories, Inc
P.O.Box 9071
Peoria, II 61614

Dear Mr. Stroh:

     Here are  jay answers to the  QC questions you raised  in  your
October 19, 1990 letter to me.

     You indicated concerns raised  recently with your data raised
during permit  reviews.  In the Environmental Protection  Agency,
the responsibility  for performing such reviews  is a  Regional one
not  a  Headquarters  one.    While  I  will  offer  my  technical
observations on  the matter shortly, I urge you  to contact Region
V  (Ms Valerie Jones,  Quality Assurance  Officer)  for  Official
guidance.   I  appreciate  that  PDC  intends to  comply with EPA's
intent  with regard  to  QC issues,  while  offering  competitive,
legally and scientifically defensible  analytical services  to  your
clients.

     Matrix spike recovery intends to furnish two important pieces
of information in the  analytical  process.  First, it will assist
you in ascertaining and correcting for co-extracted artifacts which
attenuate the  analytical procedure's  quantitation —  analytical
bias compensation.  Secondly,  it will assist you in determining if
the particular analytical scheme is applicable to the specific set
of conditions  presented by particular  samples to your laboratory.
As you will  see,  my  subsequent answers to  your questions  are
consequences of these  two uses  of matrix  spike recovery data.

     Your choice of,  "performing  a matrix  spike  on  every  waste's
TCLP extract"  is within the scope of the  June 29, 1990 TCLP rule.
As you are aware the  similarity  of samples  is more  than simply
being a TCLP leacheate, and more  than  being just a solid,  liquid,
or sludge type waste,  and probably quite process specific.   Over
time your historical data might be  marshalled to demonstrate  that
various waste  types really are identical with respect  to matrix
spike  recovery of  a given analytical  method.  You have made the
most prudent choice for now.
                                                        Priiatd on Rtcycltd Paptr

-------
     The proper reporting of non-detected analities is of concern.
The limit of detection will vary depending on the analytical matrix
as  well  as   the  cumulative  effects of  reagents,  technique,
procedure,  and materials.   The matrix spike provides  a  means of
adjusting the  level of  detection,  a compensation for analytical
bias.  When it is applied, it may as you indicate,  "force the waste
generator to either certify for that compound, or manage the waste
as hazardous." When faced with this situatation, you can, it seems
to me elect anomg several alternatives:

          o    Repeat the analysis
          o    Change the  process,   analyst, equipment handling,
               cleaning,    reagents,   instrumental   calibration
               schedule
          o    Choose a different analytical scheme

The  point being that  one  is  much  better  off  with a positive,
identified, measured, constituent than a non detect.  If I confused
you when we talked, I hope it is clear now. Actually, the way that
you were operating is quite acceptable.  But it would be incorrect
to substitute the QC check standard  for the matrix spike.

     Because the QC check standard provides different information
than the  matrix  spike,  it is not possible  to substitute one for
the  other.   The QC check standard,  reports  the  degree of control
that  exists  in  performing  the  analytical process   within  the
laboratory.   On the other hand, the  matrix  spike reports   the
adequacy of the methodology in estimating the true  value in a given
set  of  samples.    In  those  instances when  the  matrix  spike
associated with a particular batch is below that expected in  the
method, you need to correct the sample  result or alter the process
or select  a different  method.   If the QC check sample shows the
method to be in control,  it seems to me, that you may need to use
a different method (assuring yourself that it too  is in control) -
- hopefully one that has a better recovery.

     I hope that my comments have been  helpful.  They are intended
to be technical information only.  Please seek approval  from Region
V.   Also  feel  free  to  call me  with any further  questions you may
have (201-382-4761).

Used Oil Filters
     Thank you for your memorandum of August 30, 1990, requesting a
regulatory interpretation of the status of used oil filters under the
new Toxicity Characteristic (TC).  In your memorandum, you inquired
about used oil filters that are crushed in vehicle maintenance shops,
where a certain portion of the residual used oil in the filter is
separated from the filter.  The answers to the specific questions you
asked are listed below.

     1. The Toxicity Characteristic Leaching Procedure (TCLP) is
performed on used oil filters by crushing, cutting or grinding the
waste (filter plus contents) until the pieces are smaller than 1
centimeter in their narrowest dimension (and thus are capable of
passing through a 9.5 mm standard sieve).  See Step No. 7.3 of the
TCLP.  The surface area criterion referred to in Step 7.3 does not
apply to used oil filters. (Note: If the generator recycles both the
used oil and metal, you do not need to test because recycling of both
types of materials is exempted from hazardous waste regulation as
discussed below.)

     2. and 3. Assuming a used oil filter exhibits the TC, you had
inquired whether the act of crushing filters is regulated treatment
or exempt recycling.  Generally, the types of used oil filter
crushers you described would not be regulated if the used oil was
being recycled (see 40 CFR 261.6(a)(2)(iii) and (a)(3)(iii)).  That
is, since the purpose of the crushing is to remove the used oil for
recycling, ye view the crushing to fall within the used oil recycling
exemption.  The crushing may be performed on- or off-site, for profit
or not.  The determining factor is whether the used oil will be
recycled.  The filter may be shipped off-site for crushing under the
used oil exemption, providing the oil is collected for recycling.

-------
     Finally, in the sales brochures you sent,  there was mention of
an open container used to accumulate the used oil after the filter
was crushed.  (Currently, used oil accumulation by generators is not
regulated if the used oil is recycled, but EPA did propose that such
containers be kept closed.  See 50 FR 49252, November 29, 1985.)
Storage or accumulation of characteristically hazardous used oil is
regulated if the used oil is to be disposed of; in that case, the
containers must be closed except when adding or removing the used oil
(per §265.173(0)).

     Please contact Daryl Moore at (202) 475-8551 if you have any
additional questions on the applicability of the Federal hazardous
waste regulations with respect to used oil filters.

Environmental Compliance and Investigation Unit
Environmental Services Section

Transportation Building
St. Paul, MN  55155

Dear Mr. Johnson:

     On December 6, 1990, you sent a letter to our office
requesting clarification on information you had heard regarding
the applicability of the new Toxicity Characteristic Leaching
Procedure (TCLP) relative to the old Extraction Procedure  (EP)
when testing leaded paint sandblasting waste.  This letter
responds to your specific concerns.

     As you know, the Toxicity Characteristics (TC) rule was
effective on September 25, 1990 for large quantity generators,
and compliance must be achieved by March 29, 1991 for small
quantity generators.  On the compliance dates of the rule, the EP
test can no longer be used for hazardous waste identification
purposes; the new TCLP method must be used.

     The likely source of confusion is the Land Disposal
Restrictions (LDR) program, which allows use of either the TCLP
or the EP test when measuring compliance with the treatment
standards for certain arsenic- and lead-containing hazardous
waste (see 55 FR 22660, June 1, 1990; Land Disposal Restrictions
for Third Third Scheduled Wastes: Final rule; technical amendment
- enclosed).  For these wastes, the Agency specified that if a
waste does not achieve the nonwastewater treatment standard based
on analysis of a TCLP extract, but does achieve the standard
based on analysis of an EP extract, the waste is in compliance
with the treatment standard.  (This action was taken because the
data used to develop the treatment standards for these wastes
were based on EP toxicity leachate data.  Treatment standards for
characteristic wastes for the remaining EP toxic metals (D005,
D006, D007,  D009, D010, D011) and EP toxic pesticides (D012 -
D017) must be evaluated using the TCLP.)  This LDR provision is
applicable to treatment, storage, and disposal of hazardous waste
which must meet required treatment standards prior to land
/•^ i err->/~ioa 1

-------
     In summary, the information you received at the Mississippi
Valley Conference regarding the use of the EP test versus the
TCLP with respect to leaded paint sandblasting waste was, as you
have also determined, inaccurate. The only circumstance that
exists where there is an option of using either the TCLP or the
EP is when measuring compliance with the treatment standards for
certain arsenic- and lead-containing hazardous waste.

     As for the information you received from Mr. Jack Kollmer at
the November 9, 1990 luncheon, regarding the acceptance of the EP
Toxicity test for "one time operations" which includes bridge
paint removal, this was also inaccurate.

     Of course, state and local agencies may have additional
regulations that differ.  The appropriate EPA Regional office or
State and local regulatory agencies should be contacted for
additional assistance or clarification.

     If you have further questions regarding the TC rule, please
contact Steve Cochran at (202) 475-8551.

Mr. Herschel Cutler
Institute of Scrap Recycling Industries, Inc.
1627 K Street, NW
Washington, DC 20006-1704

Dear Mr. Cutler:

     I appreciate your providing us with the  documentation of your
analyses  of   the  fluff  materials.    We   are  returning  the
documentation, per your request.  Please note that in order to make
a copy for our records we were obliged to remove the binding.  I
trust this will not be too great an inconvenience.

     The comparison of the results between our contractor (MRI) and
your  contractor  (BCM)  indicated  a  difference in  some of  the
results, as you had previously pointed out.  BCM's EP Tox results
were approximately 3-30 fold lower than those  from MRI for lead
and approximately 2-10 fold lower for cadmium.  The TCLP results
were generally comparable, although BCM did have two significantly
lower lead values and one lower cadmium value.

     The attached report describes the evaluation we conducted of
the analytical documentation from both BCM and MRI.  I would like
to highlight those areas we thought were most noteworthy.

     Since pH is one of the key factors effecting the leachability
of metals into an aqueous medium,  we have carefully reviewed the
data provided  by  both laboratories with special attention to the
pH data.

     For the EP Tox procedure,  it is necessary to adjust the pH to
-5.0  +/-  0.2  with an  acetic acid  solution   (see  attachment  for
details on procedure).  MRI provided full documentation  of the pH
adjustment step,  including the  pH values before  and  after each
adjustment.   BCM  did not provide  documentation of the pH values
after  adjustment  for  some of  the samples.   Therefore,  it  was
difficult  to  fully  evaluate  the  impact   of   this   step  in  a
comparative manner.   Data from BCM  indicates that the pH before
each adjustment was much higher than 5.0 +/~  0.2,  and this may
indicate that overall, the pH was higher in the  samples  leached by
BCM than MRI.   That  may be one reason that the  concentrations of
lead  derived  from the  EP Tox  test  as performed  by  BCM  were
significantly  lower than MRI's.  Also, during the on site review,
a discussion with BCM personnel indicated that,  due to the large

-------
quantity of  acid  required and the time involved,  a  decision was
made to lower the pH to only 5.2.  This is the upper limit of the
allowable pH range,  and this factor may also help explain the lower
levels of  lead  found in  the  samples analyzed by  BCM.   (Details
provided in attached report.)

     When  using the  TCLP procedure,  a selection  must be  made
between two  different extraction fluids.   This selection is made
based on the pH of the material.   In  two cases MRI used extraction
fluid #2, whereas BCM used extraction fluid #1 in all cases.  For
both of  those  samples where  MRI used  extraction fluid  #2,  MRI
reported a higher concentration of lead than did BCM.  The use of
extraction fluid #2 for these samples had no apparent  effect on the
concentration of cadmium.   MRI provided data to support the use of
extraction fluid #2, while BCM provided no data to indicate which
fluid should be used.  (See attached report.)

     Relatively minor analytical  anomalies were  noted in some of
the data submitted by both laboratories.  It is the opinion of the
reviewer that the anomalies would not make  a major contribution to
the differences observed.   However, these are also  included in the
attached report.

     We  conclude  that the data  provided does  not  support  the
contention that the TCLP is a more aggressive test than the EP Tox.
We are aware that laboratories do have more  difficulty in using
the  EP  Tox,  and  we  feel  that  this  study  emphasizes  that
observation.   Data  from  MRI  show that  the results  are roughly
comparable between the EP  Tox and the TCLP.  We do not believe that
the  documentation provided by  BCM  is adequate  to  support  the
proposal that the two leaching procedures are not comparable.

     We appreciate  your  participation in  this  comparison study.
We feel  it has  provided   further  clarification of  our reason for
replacing the EP Tox with the TCLP.  If you have any questions on
this evaluation, please contact Alec McBride on 382-4761.

                          Sincerely,
                         David Bussard

                 REVIEW OF DATA ON FLUFF SAMPLES


     This review covers all the data provided by both BCM and MRI.
The data was reviewed for internal consistency, calculation errors,
compliance with the method, and quality control measures.

EP TOX

DH DETERMINATION
     After addition of the waste and the distilled water into the
extractor,  the  pH must be measured and  then  adjusted if  it  is
greater than 5.2.  The pH  must be monitored during the course of
the 24 hour extraction period according to the following schedule:

     •    adjust the pH of the solution in 15-, 30-, or 60-minute
          intervals, moving to the next longer interval if the pH
          does not have to be adjusted more than  0.5  pH units.

     •    continue the adjustment for at least 6 hours.

          if, at the end of the 24 hour extraction period, the pH
          of the solution  is not below 5.2,  and the maximum amount
          of acid has not  been added, the pH should be adjusted to
          5.0 +/-  0-2,  or until the maximum allocated amount of
          acid is  utilized,  and the extraction continued  for an
          additional  4 hours,  during  which  the  pH  should  be
          adjusted at 1 hour intervals.

     Data  forms provided  by  MRI allowed  for simple and  easy
determination  of  the  pH  adjustment  process.    The  following
information was included:   time and interval, pH before and after
adjustment, volume  of  acid added and cumulative  amount,  post 24
hour adjustment, and final volume of water added.

     Data provided  by  BCM was difficult to comprehend.   Only in
some cases was the time and/or interval indicated.  In those cases
where  the  pH  was  provided,  it was  apparently   the  pH  before
adjustment with the acetic acid solution.   It was  not possible to
determine what the pH was at the end of each adjustment or at the
end of  the 24 hour period and  whether  the leaching  period was
extended an additional 4 hours if the pH was greater than 5.2.  It
was also unclear whether there was any addition  of  water at the end
of the leaching period.

     It  was noted  that  the volume  of   acid  added by BCM was
approximately two fold greater than that added by MRI, which could
indicate a difference in concentration of the acetic acid reagent.
Otherwise,  one would  expect  the BCM  results to show  greater
leaching.  The incremental volumes themselves frequently differed
by approximately a factor  of 10,  most notedly at the initiation of
the leaching procedure.   MRI in most cases adjusted the pH very

-------
close to 5.0, with two excursions below 4.8 (duplicates of sample
5,5 were adjusted to a pH of 4.71 and 4.45 initially).  Since BCM
did not  provide pH data  after the addition  of acid, it  is not
possible to determine whether the adjustment procedure affected the
amount of leaching.  Conversations  between BCM personnel and the
on site  observers  from EPA indicated that the  pH  adjustment was
stopped at a pH of  5.2  due  to  the large volume of  acid added and
the  extended  length  of  time  for adjusting  the  pH.    The  pH
recordings (presumably before adjustment) which were documented by
BCM were much higher than 5.2.   This might mean that the amount of
lead  or  cadmium extracted  could  be  lower because  of  a  higher
overall average pH during extraction.

     In summary, there are several apparent inconsistencies.  MRI
added smaller increments of acid, a smaller total volume of acid,
but, in those cases  where it was possible to make a .comparison with
BCM, MRI samples had a  lower pH at the end of the 24 hour leaching
period.  It should be noted, however, that in no case did data from
MRI or BCM  show that the pH was  less  than 5.2 at the end of 24
hours.   Therefore  MRI  continued the  leaching procedure  for an
additional 4 hours  as per the method, which may have increased the
amount of  lead and cadmium  leached from the  fluff.   It was not
possible to determine  if  BCM had  an additional 4  hour extraction
period.


TCLP

Extraction Fluid Selection
     In order  to  determine the appropriate extraction  fluid for
the TCLP, one must use the following procedure:

     •    Weigh 5 g of  the solid phase of the waste (particle size
          1 mm diameter) into a 500 mL beaker or flask.

     •    Add 96.5 mL  of  reagent  water  to  the beaker,  cover with
          a watch glass and stir  for 5 minutes.

          Measure and record the  pH.  If the  pH is less  than 5.0
          use extraction fluid #1.

     •    If the pH is greater than 5.0,  add 3.0 mL  1.0  N HC1,
          cover with a watch glass,  heat to 50'  C for 10 min.; let
          cool to room temperature and record the pH.

          If the pH is  now less than 5.0, use extraction  fluid #1.
          If the pH remains greater than 5.0, use extraction fluid
          #2.

     MRI provided information which detailed the pH values at each
step.   Based on the pH,  two of  the samples  were  extracted with
fluid #2:  samples  3,12 and 5,5.   BCM used extraction fluid #1 for

-------
all samples, and did  not  provide any documentation of pH checks.
The  lead  analyses of  these  two  samples  revealed  significant
differences  in  concentration,  but  the  cadmium results  were not
significantly different.

     Sample  6,4  had a higher  concentration  of lead  and a lower
concentration of cadmium when analyzed by BCM as compared to MRI.
No differences in  procedure were noted  that  might have accounted
for this inconsistency.

     In summary/  the differences  noted in the  TCLP  results for lead
analyses in samples 3,12 and 5,5  would appear to be due to the use
of different extraction fluids.  Further information is needed to
determine whether the  correct extraction fluid was  selected by BCM.
The  data  does  not  indicate  any variation  in  method  for  the
differences- noted  in sample 6,4.

ANALYSIS 8Y FLAME ATOMIC ABSORPTION SPECTROMETRY

     MRI  documented instrument  drift  in several  instances when
using flame atomic absorption spectrometry (FAAS).  Logbooks from
MRI  describe the  techniques  used to  compensate  for  the  drift,
including  1)  manually establishing  the baseline from the strip
chart recorder and 2)  subtracting the blank from the preceding 10
samples.  The second practice is not recommended as it would tend
to inappropriately lower the concentration in the  samples analyzed
first.    Strip  chart  recordings  would  be  needed  to  verify
concentrations under the first condition.

     Examination of the BCM data also indicated possible instrument
draft.  Several QC samples had  to be reanalyzed before they met QC
limits.   Also,  several analytical  runs were  missing  from the
package.   No explanation was  given for these anomalies.   Other
observations include the following:  In the initial calibration for
lead,  BCM did  not  use  the  25 mg/L  sample  to establish  the
calibration  curve.   During  the  cadmium analysis,  the auto-zero
function was  initiated after calibration.   MRI had  a high spike
recovery  (approximately 10% higher  than expected)  for cadmium in
sample 6,4.  Reanalysis confirmed the high recovery.

     In summary, the  data  from MRI  may  be biased  low for cadmium
in EP Tox, based on the technique  for  compensating for  baseline
drift.  Cadmium results for the TCLP leachate of sample 6,4 by MRI
may be biased high.   However,  the effects of these biases on the
results would be relatively minor, probably no more than +/~ 10%.
Further information would be needed to understand what effect the
anomalies  found  in the BCM  data would  have on  the  bias  of any
results.

-------
GRAVIMETRIC DATA

     Both the EP Tox and the TCLP require the use of a 100 g
sample which must be weighed out before commencing the procedure,
BCM provided data on the weight determination of seven samples.
Several errors were identified (6 of 7).  Although these errors
would have only a nominal effect on the overall accuracy of the
results it indicates a potential weakness in the quality
assurance system.  The following data compares the results
calculated by BCM and the EPA reviewer:

SAMPLE NO       BCM            EPA
2,5            100.23          99.40
2,5            100.31          99.73
2,4            100.35         100.35
2,4            100.85         100.70
2,12           100.38         100.08
2,12           100.16          99.55
3,5            100.32         100.73

Results for all other weight determinations were not provided by
BCM nor MRI.

Quality Assurance Officer
Analytical  Technologies,  Inc.

Pensacola,  FL 32514

Dear Ms. Swanson:

       I would like  to clarify the issue of when to add the
matrix spike  in the  TCLP  procedure.

     Because  the concentration of the contaminant in the sample
is completely unknown,  a  matrix spike,  i.e., a predetermined
quantity of certain  analytes is to be added to each.sample matrix
prior to sample extraction/preparation.  This is done to monitor
the performance of the analytical method as well as the sample
preparation method and to estimate the extent to which matrix
bias or interferences  reduce the measured value of the
contaminant.

     Section  8.2.3 emphasizes monitoring the analytical procedure
as opposed  to the leaching procedure.  It is to be emphasized
that the spike monitors the analytical and preparation
procedures, i.e.,  analytical method encompasses both the
preparative and determinative steps.

     Thank  you for your inquiry about spike recovery.  I am
available to  discuss this further,  should you wish.   My phone
^number is 202-382-7458.

                               Sincerely yours,

Mr. Richard S. Leonard
Quality Assurance Director
National Environmental Testing, Inc.
Woodland Falls Corporate Park

Suite 301
Cherry Hill, NJ  08002

Dear Mr. Leonard:

     The purpose of this letter is to clarify  some  of  the
discussion in my letter of August 14, 1990 to  you  (copy  enclosed)
which was sent in response to your letter of August 1, 1990.
Specifically, I would like to revise the response to question
number 4.  The original question and the revised response  are as
follows:
     Question 4:
          Answer:
Our clients complain that when we dilute  a
sample (e.g. oil or solvent matrix) to  obtain
results that meet quality control
requirements, that the data so obtained are
"useless" because of the high reporting
limit.  How do we generate analytical data
for compliance decisions when dilution  must
be performed?

First I want to clarify that, at least  with
respect to used oil that is destined either
for recycling or to be blended as fuel, there
is no need on the part of the generator to
run a TCLP since these wastes are eligible
for the used oil exemption  (see 40  CFR
261.6(a)(2)(iii) and (a)(3)(iii).   In the
case of oily waste that is to be disposed or
solvent wastes, it is required that
generators determine if their waste is
hazardous using either knowledge of their
waste and/or the process that generated it or
by testing.  If they choose to test, then
they must use Method 1311  (TCLP).   The  Agency
is aware that running the TCLP on matrices
involving oily wastes and organic liquid
                                                          Printed on Recycled Paper

-------
                    wastes may result in labs being unable to
                    determine conclusively that the waste is or
                    is not hazardous.  In those cases, the
                    generator must use his/her knowledge to make
                    this determination.  Where no additional
                    information or knowledge is available, it
                    would probably be prudent for the generator
                    to manage those wastes as hazardous wastes.
                    Please note that in the case of liquid
                    organic wastes, it is possible that these
                    wastes may already be hazardous by virtue of
                    a hazardous waste listing (e.g., spent
                    solvents, hazardous wastes codes F001 -F005) ,
                    in which case the hazardous waste
                    determination with respect to the TC becomes
                    much less critical (e.g., you would be
                    determining if additional wastes codes
                    applied to the waste instead of making the
                    critical hazardous waste determination) .  I
                    would also add that the Agency is aware of
                    analytical problems associated with oily and
                    organic liquid wastes and is investigating
                    ways to solve them.

     I would like to apologize for any misunderstanding or
confusion which may have resulted from my earlier response, and I
hope this revised response addresses your concerns.  If you have
any additional questions related to this or other TC/TCLP issues,
please feel free to call Steve Cochran at (202) 382-4770.

Dear Mr. Goldberg:

     Thank you for your letter of January 25, 1991 concerning our
methods for ignitable liquids.

     In defining an ignitable liquid hazardous waste under RCRA,
the Agency's regulations state that flash point should be
determined by either one of two specified methods, or by any
other method which might be approved by the Administrator.  Only
one test method needs to be applied.  The choice of the method
should be based on the applicability of the method to the
material being tested.  In this case, one might consider
viscosity, among other things, in making the appropriate choice.

     I hope that this has clarified the intent.  If you need
further assistance, please call Charles Plost of my staff at
(202) 382-7458.

Dear Dr. Roelofs:

     I am writing in response to your letter of May l, 1991, to
David Bussard regarding the differentiation and equivalency of
Methods 8240 and Method 8260.

     As you are aware, both methods are determinative procedures
for the analysis of volatile organics by gas chromatography/mass
spectrometry.  The two methods are very similar and differ
primarily in the gas chromatographic column used to effect
separation.  Method 8240 utilizes  packed columns, where Method
8260 utilizes open tubular capillary columns.

     The two types of gas chromatographic columns both provide
separation of analytes targeted for analysis, but are not
technically equivalent in their separation ability.  It is Agency
policy to allow the substitution of equivalent or superior
materials within the analytical procedures of SW-846 unless
otherwise specified in regulations.  For example, Method 8240
Section 4.12.2 allows the substitution of equivalent packings.
Furthermore, Method 8000 Section 4.2 permits other packed or
capillary columns to be used provided the performance test
requirements of Section 8.6 have been met.  Therefore, capillary
columns (with or without cryogenic cooling) may be substituted
for the packed column of Method 8240, if the ability to generate
acceptable accuracy and precision by Method 8000 Section 8.6 has
been demonstrated.

-------
     We are aware that the delay in promulgating the methods of
the first update package has added further complications
regarding the utilization of Method 8260, which has not been
promulgated in its final form.  We are expediting the final
promulgation of the methods contained in the first update package
to remedy this situation as soon as possible.  If you have any
questions on this issue, please contact John Austin at (202) 382-
4761.

Dear Mr. Anderson:

     I am writing in response to your letter of May 15, 1991
concerning your particle size reduction procedure for TCLP sample
preparation of dry cell batteries.

     Your idea of using liquid nitrogen to freeze the samples
before grinding is very interesting.  Freezing at those
temperatures would certainly tend to make the sample easier to
crush afterwards.

     However, the TCLP states that one must collect a
representative sample of the waste as generated for analysis.  We
have no way of knowing whether this type of freezing will alter
or affect the sample's physical or chemical composition (and
therefore its leaching potential) in some way.  Since the
generator is ultimately responsible for making the determination
that a representative sample is collected for analysis, we cannot
make an up-front determination that this type of freezing is an
acceptable step in crushing batteries.

     If you have any further questions, please call me at (202)
475-6722.

                                       Sincerely yours,

Dear Ms. McPherson:

     I am writing in reference to your letter of April 11, 1991
concerning the handling of TCLP extractions as they apply to oily
wastes.

     We do not recommend performing the extract on the oily waste
that passes through the filter as Margo Jackisch of SAIC
suggested to you.  First of all, the TCLP determines release
potential in two steps, the first of which I will discuss here as
it specifically applies to your situation.  The initial
filtration step separates, the solid phase of a waste from its
liquid phase.  This hiiAfcir'iT phase represents the primary waste
leachate or the liquid fraction of a waste that is mobile and can
be released from a landfill.  In your case, the oil goes through
the filter and, by definition, becomes its own leachate which is
then analyzed directly.

     If your waste is a used oil that is destined for recycling,
there is no need to characterize the waste since it would be
exempt under 40 CFR Section 261.6(a)(2)(iii) and (a)(3)(iii).  it
is the decision to dispose of the waste, in lieu of recycling,
that triggers the waste characterization requirement.  If your
waste is a used oil that cannot be recycled and is destined for
disposal, generators are required to make a hazard determination.
If the generator chooses to test for the Toxicity Characteristic,
the generator must use the TCLP or an approved alternative
method, as described in 40 CFR 261.24.  The extract obtained from
the TCLP may be analyzed by any method, provided the method used
has documented QC and is sensitive enough to meet the regulatory
threshold for the constituents of concern.

     In cases where the TCLP results on used oil or oily wastes
are inconclusive, including cases where the detection limit for a
constituent is higher than the regulatory threshold, generators
may use their knowledge of the processes involved in the

-------
generation of the waste to make a hazard determination or resort
to an alternative analytical method to get an answer.  This has
been necessary with volatile organics.  At this time, the Agency
is conducting studies of an automated headspace analysis
methodology coupled with isotope dilution mass spectrometry in
order to achieve greater analytical sensitivity for all TC
volatile analytes, including vinyl chloride.  We suggest the use
of this approach.  Currently, only a working draft method (copy
enclosed) is available.  Pending the outcome of Agency studies,
the draft method will be revised and proposed for inclusion in
SW-846.

     For further assistance, please call the MICE (Methods
Information Communications Exchange) at (703) 821-4789.  Calls
are recorded on an answering machine and,  for the majority of
questions, responses are provided within 24 hours.  I hope this

Dear Ms. Harper:


     I am writing in response to your letter of June 12, 1991, in
which you request written confirmation of our phone conservation
regarding surrogate recovery.

     In judging the validity of a data  set,  surrogate analytes are
used as indicators of the procedure's ability to recover the actual
analytes of interest.  Surrogates are used to demonstrate  correct
sample preparation and the absence of matrix effects impacting the
recovery of the actual  analytes  of interest.  The use of surrogates
is  an integral  part  of  many  of  the  Agency's methods  for the
measurement of organic analyte levels.   The omission of surrogates
from  an  analytical  procedure in  which they are called for is a
deviation from the suggested or required analytical method.

     It  is  frequently  observed in the  review  of analytical data
that dilutions needed  to  achieve quantitation of the  analytes in
a  sample results  in  levels  of surrogates  which are no. longer
measurable.    The  omission or absence of  measurable levels of
surrogates provides one less tool for use in the evaluation  process
for the  assessment  of data useability.   However,  the  absence of
-surrogate data does not in itself invalidate the analysis.  If the
analysis  still  indicates that  analytes are present  at or  above
regulatory action levels, then the lack of surrogate recovery data
would have little bearing on the use of the data.  In  the  case of
no  detectable analytes,  then  there  is  no  assurance  that the
individual sample was  amenable  to the preparative procedure.

Vice President

Dear Mr. Lund:

     This letter is in response to your May 20, 1991 letter to
Mr. Alec McBride of my staff in which you requested information
and responses to questions concerning the Toxicity Characteristic
Leaching Procedure  (TCLP) and lead paint removal debris.

Q:   a. TCLP as a lead test method, is it applicable to paint
     residues?

A:   The Toxicity Characteristic  (TC) rule requires waste
     generators to determine whether constituent levels in their
     waste sample extract, or leachate, exceed specified levels.
     This determination can be based either on their knowledge of
     the processes from which the waste was generated or by
     application of the TCLP.  The TCLP is not a test method
     specifically for lead-containing waste, however, solid waste
     containing hazardous constituents, such as lead, must be
     tested with the TCLP unless the generator has enough other
     knowledge to determine whether the waste is hazardous.

Q:   b. What kind of sampling protocol should be used on drums,
     roll offs and containers of abrasive mixtures?

A:   It is important that you collect samples from drums, roll
     offs, and containers of abrasive mixtures that are
     representative of the waste.  EPA has general sources of
     guidance with respect to the development of a sampling plan.
     These include "Petitions to Delist Hazardous Waste - A
     Guidance Manual" (EPA/503-SW-85-003, April 1985) which
     discusses the concept of representative sampling (section
     7.1) and sampling techniques for various sampling
     situations, such as how you would sample a waste contained
     in drums (section 7.3).  Also eo» Ifl
     provision IS appucaoie

-------
     EPA realizes that sampling is a complex procedure and the
     representativeness of the sample is critical to the accuracy
     of the waste characterization.  Therefore, we strongly
     recommend that you contact the EPA Regional Office for your
     area and the state and local regulatory agencies for
     additional information or clarification on the appropriate
     sampling protocol for your specific situations.

Q:   c. Can on-site stabilization be done for these special
     bridge projects throughout a state without establishing a
     TSD facility?

A:   Yes.  Based on the above scenario and under the federal
     hazardous waste regulations, on-site stabilization can be
     conducted without establishing a TSD facility.  EPA allows
     for limited on-site accumulation or storage by a generator,
     regardless of whether the hazardous waste is treated or not
     treated, without the need of a permit or interim status (90
     days for generators of 1000 kg/mo or more of total hazardous
     waste and 180 (270 if waste will be transported 200 miles or
     more from site of generation) days for generators of more
     than 100 but less than 1000 kg/mo of total hazardous waste)
     (see 55 FR 10168, March 24, 1986).  In addition, generators
     (in this case C/P Utility Services would be the generator)
     must comply with all applicable Subtitle C requirements.
     For example, on-site hazardous waste stabilization or
     treatment processes must be conducted in accumulation tanks
     or containers in conformance with the requirements of §
     262.34 and Subparts J or I of Part 265.  Generators not in
     compliance with the above-prescribed requirements must
     comply with all applicable RCRA requirements as a TSD
     facility.

Q:   d. Is it allowable to inject a percentage of iron shot into
     a mineral abrasive to mask the lead in a subsequent TCLP
     test?

A:   The hazardous waste regulations do not restrict the use of
     ingredients for the purpose of preventing waste from
     exhibiting a hazardous characteristic.  In fact, this could
     be a desirable process change to make the waste less
     hazardous.  However, in this case, we understand that
     introducing iron to the abrasive only temporarily prevents
     lead from leaching from the waste, so it "masks" the lead,
     but does not really change the character of the waste.  If
     your clients choose to do this, they should be aware of two
     points:

-------
          1) If the waste passes the TCLP initially, but then
          fails later prior to disposal, the waste is hazardous,
          subject to all applicable hazardous waste rules.

          2) If the waste passes the TCLP and is disposed of as
          non-hazardous waste, the generator may, nonetheless, be
          held liable under CERCLA for any environmental damages
          caused by release of the lead into the environment.

Q:   e. Can the State DOT choose a central collection point to
     accumulate waste from several projects?

A:   Yes.  If the State DOT determines that it is necessary that
     a central collection point to accumulate waste from several
     projects be established  (e.g., in order to eliminate
     transportation or traffic impediments), and the waste is
     hazardous, prior to  movement of the waste from each site
     (i.e., "several projects") to a central collection point,
     generators are required under the Federal hazardous waste
     regulations to prepare a manifest.  In addition,  a
     transporter must not transport hazardous waste without
     having received an EPA identification number from the EPA
     Regional Administrator.  Furthermore, a transporter must
     store manifested shipments of hazardous waste in containers
     meeting the requirements of § 262.30 at the transfer
     facility  (i.e., "a central collection point to accumulate
     waste") for a period of ten days or less in order to avoid
     regulation as a TSD facility for storage of those wastes
     (see 40 CFR 262.20, 263.11-.12).

     I hope the responses to your questions are of assistance.
Of course, state and local agencies may have regulations that are
more stringent and would thus, as a practical matter,  supersede
the Federal regulations.  Furthermore, the answers to the
questions you raised are likely to vary from site to site and
from state to state depending on the particular situation and the
particular state's regulations.  Therefore, I suggest that you
contact the state waste management agency where specific paint
removal activities are planned for relevant requirements and
regulatory interpretations.  In addition, you may want to contact
the local EPA regional office, particularly if you plan on
activities within states which do not have approved hazardous
waste management programs.

Washington, D.C.  20005

Dear Mr. Campbell:
     In response  to a request made  during a recent meeting with
Mr. Jim Greene of Mobil Corporation,  we are providing you with  the
following information  on the methodologies employed in  our  1989-
1990 used 'oil sampling activities.

     To  fill  data  gaps  in  the pre-1985  generated  used  oil
characterization  data   and  to  provide   source-specific   waste
characterizations   using  improved  analytical  techniques,   EPA
initiated a sampling and analysis  program  in  1989.   To accomplish
this,  the  Agency stratified  the used  oil universe into  limited
categories based  on the  source  and  application of the  used oil.
Seven used oil categories identified include:  automotive crankcase
oils;  diesel  engine crankcase oils  from trucks and buses,  heavy
equipment, and railroads; hydraulic oils and  fluids; metalworking
oils  and  fluids;  electrical  insulating  oil;  natural  gas-fired
engine oil; and aircraft and marine engine oils.

     The  Agency   developed   sampling   strategy  by   conducting
literature research, data base searches, and  telephone interviews
with industry,  State,  and  local  officials, as well as  telephone
book listings.  Each  facility identified as a  used  oil  generator
was defined as a unit  selected on a random  basis in one of the used
oil categories noted above.

     To  use  available  funds effectively by  focussing  on  the
analysis  rather  than  the  national   representation of  used  oil
sample, the sampling activities were  undertaken in the Washington,
D.C. area,  unless  samples of used oil from a specific segment could
not be obtained there.   The sampling program was  not  intended to
characterize variations in used oil based on geographical location,
since it is assumed that no significant differences in constituent
concentrations are  attributable  to geographic area.
                                                          Pruutd on Ricycltd Paptr

-------
     When possible, samples of "as generated" used oil and facility
storage  tanks or  containers  were  taken.    This allowed EPA  to
determine "as-generated" constituent  concentrations and  the extent
of adulteration endemic to the generator.

     The Agency developed field  procedures to sample numbering and
labeling, equipment use and decontamination,  sample protocols, and
sample containerization and preservation, as  well  as documentation
of sampling  activities.   Chain  of custody  forms accompanied each
shipment of  samples from the field to the laboratory.

     The analytical program was  designed to characterize used oils
with respect to the compositional concentration of the constituents
of concern and with  respect to  the Toxicity Characteristic (TC) .
In order to do this, the Toxicity Characteristic Leaching Procedure
(TCLP) was applied to used oil samples, and after filtration, the
liquid phase  (filtrate) of the samples were analyzed for selected
constituents of concern using analytical methods from SW-846, "Test
Methods  for  Evaluating Solid Waste  (Physical/Chemical Methods),
Third Edition," as noted in the table on the next page.

     For volatile organic contaminants, the Agency found that the
traditional  purge  and  trap GC/MS method  (Method 8240)  did not
provide  detection limits  that  were  sufficiently  low.    As  an
alternative,   the  Agency  has  modified  an   existing  headspace
screening method (Method 3810) to include isotope dilution.  This
modified method includes the addition of several  standard isotopes
that correspond to each of the target analytes.  For semi-volatile
organics  analyses, the Agency  had  similar difficulties.    The
existing SW-846 methods were adequate  for analyzing most samples,
but  the   used  oil  matrix  required  dilutions  that  yielded
unacceptable detection  limits.   To improve the detection levels,
the Agency utilized a specific ion monitoring  (SIM) option  on the
GC/MS.  Instead of  scanning the sample for a full spectrum of semi-
volatile  compounds,  the  Agency found  that analytes  with  lower
concentration  could be easily detected using SIM.

     Attachment 1  is a copy of the Sampling  and Analysis Plan for
the Characterization of Used Oil, and Attachment 2 is the table of
SW-846 Methods employed to characterize used oil.  The results of
the sampling and analysis effort wili be publicly available  at the
time of publication of the used oil  proposed rule.  Thank you for
your interest  in EPA's used oil program.

MEMORANDUM

SUBJECT:  Lead Paint Removal Debris and the TCLP Procedure

FROM:     David A. Bussard, Director
          Characterization and Assessment Division

TO:       Toxicity Characteristic  (TC) Rule Regional Contacts
          Regions I - X


     Since -the promulgation of the TC rule (March 29, 1990),
there have been a number of generator and state inquiries
regarding the applicability of the TC rule (i.e., Toxicity
Characteristic Leaching Procedure  (TCLP)) to lead-paint removal
debris.  Specifically, questions have been raised regarding the
regulatory status of lead-paint removal debris that are generated
with a mineral abrasive which includes an additive which "masks11
(intentionally or not) the lead in a subsequent TCLP test.  We
anticipate that you will be receiving similar inquiries regarding
the regulatory status of the above-mentioned waste.

     In summary, there are two scenarios that may exist regarding
the addition of agents or additives to mineral abrasives that are
used for lead paint abatement projects:

     1. Agents or additives that are mixed with the mineral
     abrasive prior to the abatement process (i.e., before a
     waste is generated) for purposes of preventing waste from
     exhibiting a hazardous characteristic.

     2. Agents or additives that are mixed with the mineral
     abrasive subsequent to the abatement process (i.e., after a
     waste is generated) for purposes of preventing waste from
     exhibiting a hazardous characteristic.

     The purpose of this memorandum and the attachment is to
provide you with a copy of a letter that responds to these and
other questions regarding the applicability of the TC rule and
hazardous waste regulations to lead-paint removal debris.

Dear Dr. Kipnis:

     I am writing in response to your letter of September 13 ,
1991 requesting an exemption from the particle size reduction
step in the Toxicity Characteristic Leaching Procedure  (TCLP) .

     The RCRA hazardous waste regulations allow a generator to
use his/her knowledge of a waste (which could include previous
testing data on wastes known to be very similar) or the processes
that generated a waste to determine if it should be regulated as
a hazardous waste.  We do not require you to test.  If you decide
to test for the Toxicity Characteristic, however, you must use
the TCLP  (Method 1311).  At this time, the particle size
reduction step is included in the TCLP, and laboratories are
required to follow the steps in the method.  Because TCLP does
not explicitly describe how to reduce the particle size of all
materials, a laboratory analyst must use his/her best
professional judgement for determining an appropriate method.
This might include cutting, crushing or grinding.  The
responsibility lies with the generator to make that
determination .

      In addition,  the TCLP states  that one must collect a
 representative sample of  the waste as generated for analysis,   if
 you scrub your subsamples prior  to TCLP testing,  then  you may  not
 be testing a representative sample.   We have  no way of knowing
 whether the  cleaning  procedure will alter  or  affect the sample's
 physical or  chemical  composition (and therefore its laaching
 potential) in  some way.   Sinoe tha generator  ig ultimately
 responsible  for mafrinrr 1-hP   -           ---    -
 sample  is -collected  for analycic,  we  cannot make  an up-front
 determination  that your proposed method  is an acceptable or
 appropriate  step.

Dear Mr. Miller:

     I am writing in reference to your letter of October 8, 1991,
to Alec McBride, concerning the handling of TCLP extractions as
they apply to.liquid wastes, including oils and solvent-based
products.

     It is important to keep in mind that EPA does not require
testing to determine whether a waste is hazardous; the generator
may use other information  (such as knowledge of the process by
which the waste was generated) in making that determination.
Also, certain oily material destined for recycling, is exempt
(under Section 261.6(a)) from hazardous waste management
requirements.

     Liquid hazardous wastes are subject to hazardous waste
management requirements regardless of whether they are destined
for landfill disposal.  As a result, there are many reasons why a
generator or transporter would and should want to test the waste
that they manage.  For example, a generator may need to determine
what types of storage, handling or transport requirements are
applicable to the waste.  The generator may also need to test the
waste to determine compliance with the RCRA Land Disposal
Restrictions program, under which wastes are subject to
requirements for treatment by specified technologies prior to
land disposal.

     Given these considerations, if the generator still wishes to
test his/her waste for the Toxicity Characteristic (TC)
determination, then the TCLP must be followed.  Once the fluid to
be analyzed has been obtained  (from either the initial filtration

-------
 step or the leaching procedure) , the laboratory may use any
appropriate determinative step for the analysis.  If the methods
currently in SW-846 do not achieve the required detection limits,
then other methods should be used.  This has often been necessary
with volatile organics for oily matrices.  At this time, the
Agency is conducting studies of an automated headspace analysis
methodology coupled with isotope dilution mass spectrometry in
order to achieve greater analytical sensitivity for all TC
volatile analytes.  We suggest the use of this approach be
considered.  Currently, only a working draft method (copy
enclosed) is available.  Pending the outcome of Agency studies,
the draft method will be revised and proposed for inclusion in
SW-846.

     For further assistance, please call the MICE (Methods
Information Communications Exchange) at  (703) 821-4789.  Calls
are recorded on an answering machine and, for the majority of
questions, responses are provided within 24 hours.  I hope this

Ms. Sharon Meves
Quality Programs Coordinator
WMI Environmental Monitoring Laboratories, Inc.
2100 Cleanwater Drive
Geneva, Illinois  60134

Dear Ms. Meves:

     I am writing to  you in response to your inquiry of November
18,  1991,  concerning   the  handling  and  analysis  of  samples
containing volatile organic compounds.   You do  not  mention any
specific matrix in your letter,  but the tone  of  it indicates to us
that your questions refer to aqueous  samples.   My responses are
also limited to samples  regulated under the Resource Conservation
and Recovery Act, and represent the point of  view of the Office of
Solid Waste.

     In general, aqueous samples should be hermetically sealed in
volatile organic vials  at the time of  sampling,  and  must not be
opened prior to  analysis to preserve their integrity.   The vials
should be completely filled at the time of sampling, so that when
the septum  cap is  fitted  and  sealed,  and the  vial  inverted, no
headspace is visible.  At the time of analysis, the aliquot to be
analyzed should  be  taken from the vial  with a gas-tight syringe
inserted  directly   through  the  septum of  the  vial.   Only  one
analytical sample can be taken from each vial.  If these guidelines
are not  followed,   the  validity of  the  data generated  from the
samples is suspect.

     The following  is the response to your specific questions:

     1)   The sample should  exhibit  no headspace "at the time of
          sampling" as I have previously mentioned.  However, due
          to differing solubility and diffusion properties  of gases
          in aqueous  matrices at  different temperatures,  it is
          possible for the sample to generate some headspace during
          storage.   This hegdagmoB4Oii 11 appear in the form  of micro
          bubblefe,  anishctuJ^naV^tivalidatela sample for v.Dlat|les

-------
     2)    The presence of a macro bubble in a sample vial generally
          indicates either improper sampling technique or a source
          of gas evolution within the sample.   The latter case is
          usually accompanied by a buildup of pressure within the
          vial, (e.g. carbonate containing samples preserved with
          acid).   Tom Bellar  of  the Environmental  Monitoring
          Systems Laboratory in Cincinnati (EMSL-ci)  (unpublished
          data) states from a study that he did several years ago
          that "pea-sized" bubbles (i.e. bubbles not exceeding 1/4
          inch  or  6  mm in  diameter)  did  not adversely  affect
          volatiles data.  These bubbles were generally encountered
          in  wastewater samples,  which  are  more  susceptible to
          variations  in  gas  solubility  than  are  groundwater
          samples.

     3)    There  is  no reason  to  "flag" data  from  acceptable
          samples.   However,  finite  volatiles concentrations (i.e.
          values above  detection  limits)  from samples containing
          excessive  headspace  should  either  be  identified  as
          minimum values  or  discarded  and new samples  should be
          taken.  Non-detectable results are invalid.

     If you have any further  questions, please call me at 202-260-
7459.

     On December 11, 1990 and April 18, 1991 you sent a letters
(#8026 - Ser 50222/U5224, - Ser PM4/U5471) to our office
requesting that the Navy be exempted from the provisions of the
Toxicity Characteristic Leaching Procedure (TCLP) when
determining if munitions items (DOT Class C, Hazard Class 1.4),
which are being processed through an incinerator for disposal,
exhibit toxic characteristics.  This letter responds to your
specific concerns.  I want to apologize for not responding sooner
to your initial letter.

     Under the existing regulations, persons who generate solid
waste are not specifically required to test their waste to
determine whether they exhibit the Toxicity Characteristic or any
other characteristic.  Instead, solid waste generators are
required to make a determination as to whether or not their waste
are hazardous (see 40 CFR 262.11).  This determination may be
made by either applying knowledge of the waste, the raw
materials, and the processes used in its generation or by
testing.

     In your initial letter you stated that, "the TCLP
requirement to reduce particle size for toxicity determination
should not be applicable because of the inherently unsafe
procedure of crushing, cutting or grinding of munitions items."
The Agency recognizes that the particle size reduction
requirement (step. 7.3 - TCLP) could create an inherently unsafe
situation when testing these items.  Therefore, we suggest that
determinations for these items be made by using knowledge of the
process or any other available data that characterizes the
properties of the above prescribed waste (e.g., EP Toxicity
results).

     On January 11, 1991, our office called Mr. Keith Sims,  and
on January 14, 1991 we spoke with Mr. J. Lawson, both of your
office, regarding the Navy's request for exemption from the TCLP.
In our phone conversations, we explained that the TC rule does
not require generators to test in order to make a hazardous waste
determination, as described above.  Based on their knowledge of
the process, if thev think tne*ctaj*Nafcove munitions items would

-------
fail the TCLP-extract analysis for lead or dinitrotoluene, then
these wastes could be declared as hazardous, and no testing would
be necessary.  However, these wastes would have to be managed and
disposed of according to Subtitle C requirements.  Both Mr. Sims
and Mr. Lawson acknowledged that they understood our explanation
and requested that we send you the above clarification in
writing.

     Of course, State and local agencies may have additional
regulations that differ.  The appropriate EPA Regional office or
State and local regulatory agencies should be contacted for
additional assistance or clarification.

     If you have further questions regarding the TC rule, please
contact Daryl Moore at  (202) 475-8551.

                                     Sincerely yours,

Dear Mr. Fishback:

     This letter is to follow up on a discussion with Mr. Richard
Ross of your office in which he requested a written clarification
of the applicability of certain analytical methods for conducting
testing under the toxicity characteristic regulation.

     The Technical Assessment Branch in EPA's Office of Solid
Waste is responsible for developing and promulgating analytical
methods for EPA's hazardous waste program, including the
Extraction Procedure (EP) leaching test.  Until September 25,
1990, when changes to the toxicity characteristic (TC) became
effective, the testing protocol for determining compliance with
the TC was the EP test.  The EP test was described in Appendix II
to 40 CFR Part 261.  See 40 CFR Part 261, Appendix II (Superceded
test) (1990).  Appendix II described the various steps of the
leaching procedures itself and then stated that the test methods
to be used for analyzing the 14 compounds were those specified
in "Test Methods for the Evaluation of Solid Waste, Physical/
Chemical Methods", known as SW-846.

     Until June 21, 1990, the methods specified in SW-846 for
arsenic, selenium, and mercury were Atomic Absorption, Furnace
Technique (methods 7060 and 7740 for arsenic and selenium,
respectively); Atomic Absorption, Gaseous Hydride (methods 7061
and 7740 for arsenic and selenium, respectively); and Manual,
Cold Vapor Technique (methods 7470 and 7471 for mercury).  On
June 21, 1990, the Agency also promulgated method 6010
(Inductively Coupled Plasma Atomic Emission Spectroscopy) for
arsenic and selenium.  The Agency has not promulgated an Atomic
Absorption, Direct Aspiration Method for analyzing arsenic,
selenium, or mercury.

Dear Senator Gorton:

     Thank you for your letter of November  3,  1991,  regarding
Chuck Burr's concerns about the disposal of used automobile
antifreeze.

     My staff contacted Mr. Burr to discuss his concerns
regarding a recent revision to our toxicity test and to the
regulations that identify wastes as hazardous.  Mr.  Burr
indicated that there is a lack of guidance  for businesses  in
managing their antifreeze.  We supplied him with information
about the current regulations and exemptions regarding the
disposal of antifreeze.  I have also enclosed  some guidance
documents that the Environmental Protection Agency  (EPA) has
developed for small businesses to make it easier to  comply
with the Resource Conservation and Recovery Act.

     It should be noted that EPA does not regulate household-
generated antifreeze.  In the case of antifreeze generated by
Businesses, EPA regulates only antifreeze that fails the revised
toxicity test.  It may be of interest to you that we have
received some information from used automotive antifreeze
recyclers and the used antifreeze collection industry, indicating
that used antifreeze may, in some cases, fail  the revised
toxicity test and therefore be a hazardous  waste.

     In addition, EPA allows businesses that generate less than
100 kg/month  (about 30 gallons) of hazardous waste to manage
their wastes without complying with the EPA hazardous waste
regulation.  We are considering further special exemptions so
that small business owners can comply more  easily.   We expect
to propose this concept within the next few months.

Dear Ms. Mat is:

     I am writing in response to your letter of August  16,  1993
requesting clarification of the status of discarded off-gas
piping, equipment, and off -gas scrubber solution from a tank
system used for storage of a commercial chemical product  listed
in 40 CFR 261.33.

     The off-gas scrubber solution is not considered to be  the
listed hazardous waste because the gas contained in the solution
is derived from a product, not a waste.  Therefore, the derived-
from rule is not applicable.  However, when the off-gas scrubber
solution is being discarded it is a solid waste and you must
determine if it exhibits a characteristic.  If so, the  scrubber
solution must be handled as a characteristic hazardous  waste.

     The liquid residuals removed from the tank are the listed
commercial chemical product.  However, if the container from
which the residuals are removed is empty, the residuals are not
subject to regulation under RCRA.  The definition of "empty"
differs based on whether the commercial chemical product  is
listed as a "P«  (40 CFR 261.33 (e)} or "U" (40 CFR 261.33  (f ) )
waste; 40 CFR 261.7 discusses what constitutes an empty container
for both wastes.  In the case of a "U" waste, 40 CFR 26l.7(b)(l)
states that "the container is empty if all wastes have  been
removed using the practices commonly employed to remove materials
from that type of container. . .and no more than 2.5 centimeters
(one inch) of residue remain on the bottom of the container or
inner liner, or no more than 3% by weight of the total  capacity
of the container remains in the container or inner liner  if the
container is greater than 110 gallons in size."

     In the case of a "P" waste, 40 CFR 261. 7 (b) (3) states  that a
container or inner liner... is empty if the container or inner
liner has been triple rinsed using a solvent capable of removing
the commercial chemical product or the container 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."

-------
     In the case of the liquid rinsate, if the material is
rinsate from empty containers or from containers that are
rendered empty by that rinsing, then by virtue of 40 CFR
261.3(a)(2)(iv)(D), the rinsate is not the listed hazardous
waste.

Mr. Gregory L Crawford
Vice President, Recycling Operations

Pittsburgh, PA 15220

Dear Mr. Crawford:

      Over the past several years we have received numerous questions concerning
the regulatory status of used aerosol cans under the Resource Conservation and
Recovery Act (RCRA) hazardous waste regulations.  I understand that confusion about
these issues may be hindering your efforts to increase steel aerosol can recycling in
this country.  As  environmentally protective recycling is an important part of the
Agency's waste management goals, I hope that this letter will help to answer some  of
these questions.

RESIDENTIAL AEROSOL CANS

      First, I would like to emphasize that under the federal RCRA regulations,
household waste (including aerosol cans) is excluded from the definition of hazardous
waste (40 CFR 261.4(b)(1)).  Thus, any aerosol cans generated by households are  not
regulated as hazardous waste.  Because this  exclusion attaches at the point of
generation (i.e., the household) and continues to apply throughout the waste
management cycle, household aerosol cans collected in municipal recycling programs
and subsequently managed in recycling programs continue to be  excluded from the
hazardous waste management regulations.

      The data you submitted1 appear to confirm that the majority of used residential
aerosol cans contain very little residual product or propellent.  Along with your
    ; Texas Steel Aerosol Can Recycling Program, Final Report; Steel Can Recycling
Institute (now Steel Recycling Institute); December 7, 1992.
                                                               Recycled/Recyclable
                                                         r\  
-------
experience working with many of the 600 or more communities currently recycling
these cans, the data suggest that aerosol cans can be effectively recycled.  The
Agency does recommend that communities running residential steel recycling
programs educate their participants to recycle only empty steel aerosol cans.
Participants could also be educated to: 1) purchase only the amount of consumer
products that they need to minimize the quantities of unused products, 2) give unused
products to someone else who can use them, 3) take unused or partially full
containers to a household hazardous waste collection program if available, or 4)
dispose of the partially full containers as directed on the label.

COMMERCIAL/INDUSTRIAL AEROSOL CANS

      I understand that you are also interested in facilitating the recycling of aerosol
cans generated by commercial or industrial generators. The remainder of this letter
discusses only these non-household waste items.

      We have been asked whether aerosol cans exhibit the characteristic of
reactivity. At this time, the Agency is not able to  determine whether various types of
cans that may have contained a wide range of products are reactive.  However, a
steel aerosol can that does not contain a significant amount of liquid would clearly
meet the definition of scrap metal (40 CFR 261.1(c)(6)), and thus would be exempt
from RCRA regulation under 40 CFR 261.6 (a) (3) (iv) if it were to be recycled.
Therefore, a determination of reactivity or any other characteristic would not be
relevant. Aerosol cans that have been punctured so that most of any liquid remaining
in the can may flow from the can (e.g., at either end of the can), and drained (e.g.,
with punctured end down), would not contain significant liquids.

      It should be noted that since the process of emptying the aerosol cans is part
of a recycling process (i.e., scrap steel recycling), this activity would be exempt from
RCRA regulation under 40 CFR 261.6(c) (except as specified in 40 CFR 261.6(d)).
The Agency recommends that these activities be conducted in a safe and
environmentally protective manner and that care be taken to properly manage any
contents removed from the container (both liquids and gases).  Any liquids or
contained gases removed from aerosol cans may be subject to regulation as
hazardous wastes if they are listed in Subpart D of 40 CFR Part 261 or if they exhibit
any characteristics of hazardous waste as described in Subpart C of 40 CFR Part 261.

      We have also been asked to determine whether used aerosol cans would meet
the definition of "empty" under 40 CFR 261.7. Again, if the steel cans are being
recycled, it is not necessary to determine whether they are "empty" under the criteria
listed  in 40 CFR 261.7.  As long as an aerosol can being recycled does not contain
significant liquids, the can is exempt as scrap metal. However,  in order to dispose of
a can as non-hazardous waste (rather than recycle it), a generator would have to
determine that the can is empty under 40 CFR 261.7- (or that the product it contained

-------
was not hazardous), and that the can Itself is not hazardous.  If a can is to be
disposed of, and either contains or is hazardous waste, it must be managed under all
applicable regulations.

      Please be aware that this letter addresses only the federal hazardous waste
regulations.  Authorized State agencies implement the RCRA program in their states
(although some parts of the program may be implemented by the U.S. EPA Regions),
and that state regulations may be more stringent than the federal regulations.  Anyone
managing aerosol cans should contact the appropriate state environmental agency or
U.S. EPA Regional Office to determine how the regulations of that particular state will
apply to their activities.

      I hope this information  is useful in  your efforts to increase steel recycling.
Thank you for the assistance  that you and  the Steel Recycling Institute have provided
my staff in researching these  issues.  If you have any further questions, please call
Charlotte Mooney of my staff  at (202) 260-8551.

Director, Industrial and
  Hazardous Waste Division
Texas Natural Resource
  Conservation Commission
P.O. Box 13087
1700 North Congress Avenue
Austin, Texas 78711-3087

Dear Ms. Ferguson,

     This letter responds  to your letter dated November 5, 1992,
requesting an interpretation of  the Resource Conservation and
Recovery Act (RCRA) regulations  as they apply to hazardous waste
fuels.  Specifically, you  asked  for interpretation and guidance
regarding whether fuels containing recovered light hydrocarbon
would be regulated as solid  wastes or as products under RCRA.  I
apologize for the long delay in  responding to your letter.

     Your letter provides  examples of three companies that
generate light hydrocarbon streams in the production of a primary
product and that wish to sell the streams as fuel additives
and/or burn them as supplemental fuel in on-site boilers.  Your
question is whether these  secondary materials are RCRA solid
wastes.

     The determination of  whether a secondary material is or is
not a solid waste is a complex,  largely substance- and situation-
specific decision.  Therefore,  it is difficult to make a general
statement regarding the regulatory status of the light
hydrocarbon secondary materials  referred to in your letter.   In
essence, the solid waste determination depends on whether the
material in question is considered a "by-product" or a "co-
product" of the production process.  By-products burned  for
energy recovery are regulated as solid wastes under RCRA; co-
product fuels  (i.e., products)  are not.  The by-product/co-
product determination is based  on a number of factors, each of
which must be evaluated in a case-specific context.

     A by-product is defined in  RCRA as "a material that is not
one of the primary products  of  a production process and  is not
solely or separately produced by the production process" (40 CFR
261.1(c)(3)).  The preamble  to  the 1985 Definition of Solid Waste

                                                    Recycled/Recyclable
                                                    Printed with Soy/Canoia Ink on paper thai

-------
final rule provides clarification of EPA's intent regarding what
constitutes a by-product.  It explains that EPA means to include
as by-products, "materials, generally of a residual character,
that are not produced intentionally or separately, and that are
unfit for end use without substantial processing" (50 FR 625,
January 4, 1985).

     While there is no explicit regulatory definition of the term
co-product, the preamble to the 1985 rule also provides some
clarification as to what would be considered a co-product, as
distinct from a by-product, under RCRA.  The preamble describes
co-products as, "materials produced intentionally, and which in
their existing state are ordinarily used as commodities in trade
by the general public" (50 FR 625, January 4, 1985).

     Based on these definitions, several factors must be
considered in deciding whether a secondary material is a
legitimate product or a waste.  They include, for example,
whether the material constitutes a separate production stream,
whether it is fit for end use essentially as is or must undergo
substantial additional processing prior to use, whether it is
residual in nature or a highly processed material intentionally
produced for sale to the public, whether a legitimate market
exists for the material,  etc.

     Given the information you provided, we agree that at least
some of the materials described in your letter may potentially
meet the definition of solid waste.  If the materials meet the
solid waste definition and are further determined to be hazardous
under RCRA, they must be burned in compliance with the 40 CFR
Part 266 standards for burning of hazardous waste in boilers and
industrial furnaces.  We recognize, however,  that the existing
solid waste criteria may be ambiguous and difficult to apply.
Furthermore, we are aware that the application of those criteria
may inappropriately limit the use of clean alternative fuels.
Consequently, the Office of Solid Waste (OSW)  is currently
evaluating the issues surrounding the regulatory status of "clean
fuels" through two separate but related efforts.

     First, as you know,  the Definition of Solid Waste Task Force
has been established to review the overall system by which
hazardous wastes are defined and recycling of secondary materials
is regulated.  The Task Force will submit their recommendations
to me on how to improve the regulatory and/or statutory framework
for regulating secondary materials in March,  1994.  We expect the
recommendations to reflect the issues raised by you and other
members of the Association of State and Territorial Solid Waste
Management Officials' subcommittee who have participated in the
Round Table process.

     Second, for the past several months,  EPA has been developing
a "Hazardous Waste Combustion and Waste Minimization Strategy,"

-------
to reduce the amount of hazardous waste produced and strengthen
the controls on hazardous waste combustors  (incinerators, boilers
and industrial furnaces) .  Through this effort, EPA is
reexamining its existing regulations and policies on waste
combustion in order to develop an integrated program for source
reduction and waste management.  For further information on the
combustion portion of the strategy, you can contact Fred Chanania
at (703) 308-8420.

     Both of these efforts provide forums through which we hope
to address the "clean fuels" issue (e.g., identifying "clean"
fuel not subject to RCRA) in the context of the overall program.
In the meantime, if you have additional questions or need further
information on this issue, please contact Mitch Kidwell of my
staff at (202) 260-8551.

                                   Sincerely,

Dear Mr. Guidai

     Thank you for the opportunity to review the reports which
you recently submitted to me regarding the Naval hJuclear
Propulsion Program's  (NNPP) spent nuclear reactor fuels and the
RCRA hazardous waste determination.  In these reports, the NNPP
detailed its efforts at characterizing the Program's spent fuels
based both on "process knowledge" and actual analyses conducted
in hot cells in accordance with the Toxicity Characteristic
Leachate Procedure (TCLP).

     First, I want to commend your staff for the extraordinary
efforts undertaken to characterize actual samples of irradiated
fuel for the Toxicity Characteristic.  I recognize that it is a
fairly daunting task to sample and analyze these highly
radioactive materials, and I believe your Program's efforts are
unprecedented in this respect.  I also would like to thank Mark
Neblett of your staff for his efforts to clarify for my staff
portions of the draft report that accompanied your September 20,
1993 letter to EPA, and to hand deliver additional materials to
assist the Office of Solid Waste  (OSW) in its review.

     The entire report was reviewed by both EPA mixed waste
policy staff in the Permits and State Programs Division, and RCRA
testing methods experts in our Characterization and Assessment
Division.  Based on my staff's review, the Office of Solid Waste
concurs with the reports' conclusion that the NNPP's spent
reactor fuels and assemblies should not present any of the
characteristics that  identify RCRA hazardous wastes.  Our
concurrence is based on our review and agreement with the NNPP's
"process knowledge" analysis, the TCLP analytical procedures
used, and the TCLP/quality control measures described in your
report.  We also believe, given the conservative assumptions
which the NNPP employed in selecting representative spent fuel
samples  (i.e., selecting samples that contained the highest
possible concentrations of RCRA hazardous ir.etals) , that the
reports support a general determination that none of the
Program's spent reactor fuels would be classified as RCRA

-------
hazardous wastes.  This latter conclusion is, of course,
conditioned on the completeness and accuracy of the information
shared with EPA on the Program's "process knowledge,"
particularly with regard to projecting the TCLP test results
obtained to other fuels than those that were actually involved in
the testing.

     As you are aware, EPA delegates the authority to implement
the Subtitle C RCRA program to the States.  Currently, 35 states
and one territory have received from EPA the approval to regulate
RCRA mixed waste.  We recommend that you share your results with
the appropriate hazardous waste personnel in those States where
the spent reactor fuel is managed.

     Again, we appreciate the opportunity to evaluate the results
of the spent fuel "process knowledge" analysis and TCLP test.  If
you have any questions on EPA's review, please contact Susan
Jones, at (703) 308-8762.

                              Sincerely,

Dear Mr. Joseph:

     Thank you  for your letter of August 4,  1993, concerning the
requirements for disposal of discharged M-44'Cyanide Capsules
that originally contained a sodium cyanide pesticide.  Your
letter identifies two exemptions from the Resource Conservation
and Recovery Act  (RCRA)  hazardous waste regulations that you
believe may apply to discharged M-44  capsules.   It appears that
either or both  of these exemptions may apply to your activities.
Each exemption  is discussed in detail below.  Please note that
because these exemptions are conditional and self-implementing,
it is your responsibility to determine whether or not the
conditions of the exemptions are met.  Because generation of this
waste is not likely to  fit  the typical hazardous waste generation
pattern, it may also be necessary to  contact the agency
implementing the hazardous  waste program in the areas where the
pesticide is used to determine the applicability of these
exemptions.

     First, you identify the empty container provision of 40 CFR
261.7 as a possible exemption.  Since the capsules contained a
sole active ingredient  formulation of sodium cyanide (acute
hazardous waste P106, see 40 CFR 261.33(c) and (e)), 40 CFR
261.7(b)(3) would be the appropriate  standard.   Specifically, 40
CFR 261.7(b)(3) indicates that a container that has held an acute
hazardous waste listed  in 40 CFR 261.33(e) is considered empty
if: 1) the container has been triple  rinsed, or 2) the container
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.  In your  letter you indicated that
the fired capsules are  cleaner than triple-rinsed pesticide
containers.  If the capsules have been cleaned (i.e., the
pesticide removed) by a method that has been shown to achieve
removal equivalent to triple rinsing, they would be considered
empty containers.  This exclusion is  self-implementing; there is
no formal EPA approval  process for using an alternative cleaning
method under 40 CFR 261.7(b)(3).  We  would suggest that persons


                                                     Racyctod/ftocyclabl*
                                                     PilnMd with Soy/Canola Ink on paptr that
                                                     contains at lattt 80% pacydad flbar

-------
using an alternative cleaning method document t^e equivalency of
the method and its use.  Note £hat under 40 CFR 262.40(c),
generators of hazardous wastes  are required to maintain records
of waste identification determinations.  It might also be useful
to discuss the use of an equivalent removal method with the
agency implementing the hazardous waste regulations in the area
of use; the state hazardous waste agency if authorized, or the
appropriate EPA regional office if the state is not authorized.

     Second, you identify the Conditionally Exempt Small Quantity
Generator (CESQG) provision of 40 CFR 261.5 as a possible
exemption.  Specifically, 40 CFR 261.5(e) and  (f) indicate that a
generator who generates less than one kilogram of acute hazardous
waste in a calendar month is a CESQG and is not required to
manage that acute hazardous waste in compliance with the full
hazardox .  waste regulations providing that the generator complies
with certain requirement,'  set forth in paragraph (f) .  In
addition to waste identification and accumulation requirements,
the generator is limited to managing the acute hazardous waste in
an on-site or off-site facility that meets one of five criteria
listed in 40 CFR 261.5(f)(3)(i)-(v).  It should be noted that
this requirement would apply to burial of hazardous wastes as
well as to burning.

     The one kilogram quantity limit applies to each generator,
which is defined in 40 CFR 260.10 to mean "any person, by site,
whose act or process produces hazardous waste ..."  Depending on
where and how the M-44 Cyanide Capsules are used, it is possible
that each person or organization using the capsules in an area
(and/or the owner of the land on which they are used) may be
considered a separate g  erator.  As long as any such generator
generates less than one  .ilogram of acute hazardous waste in a
month, that waste may be managed under the reduced provisions of
40 CFR 261.5(e) and (f).   Users of M-44  Cyanide Capsules  should
contact the appropriate state or EPA regional office for
assistance in defining individual generators based on the facts
   the pestic-'.de use.  Alternatively, if the Animal and Plant
  .alth Inspection Service is the only user of these capsules, it
may be possible to identify the total quantity generated
annually, and from that determine that all generators generate
less than one kilogram per month.  Please note that any
undischarged capsules that are disposed of would also be included
in this calculation.
     Except Conditionally Exempt Small Quantity Generators,
discussed below.

     2If the actual weight of residue remaining in the container
can be identified, it is not necessary to include the weight of
the container in this quantity.

-------
     Under 40 CFR 261.5(f), a CESQG of less than one kilogram per
month of an acute hazardous waste may dispose of that waste at
one of several types of facilities.  For M-44 Cyanide Capsules,
the most useful type of facility is likely to be one that is
"permitted, licensed, or registered by a state to manage
municipal or industrial solid waste" (40 CFR 261.5(f)(3)(iv)).
Please find enclosed a letter that further explains this
requirement.  It may be possible to obtain permitting, licensing,
or registration from the appropriate state agency to dispose of
M-44 Cyanide Capsules at the site of use or elsewhere in the
field (burning or burial).  Alternatively, the capsules would
have to be disposed of at an off-site facility meeting one of the
listed criteria.

     This letter addresses only the federal hazardous waste
regulations.  Authorized state agencies (or in some cases the
appropriate EPA Regional Offices) generally implement the RCRA
program within each state, and state regulations may be different
(although no less stringent) than the federal regulations.  Most
relevant for you may be that some states do not recognize the
CESQG exemption, or may have different quantity limits than the
federal regulations.  Thus, persons using M-44 Cyanide Capsules
should contact the state environmental agency (or EPA regional
office)  for the area in which the capsules will be used to
determine how the regulations or that particular state will apply
to disposal of the capsules.

     Thank you for your interest in the safe and environmentally
sound management of these wastes.  If you have any further
questions please contact Charlotte Mooney, of my staff, at (202)
260-6926.

                              Sincerely,

Dear Mr. Campbell:

     Thank you  for your letter of November 12, 1993, commenting
on our letter of  October 7,  1993,  concerning regulation of waste
aerosol cans under the Resource Conservation and Recovery Act
(RCRA) hazardous  waste regulations.   We appreciate your interest
in the safe and environmentally protective management of these
wastes.

     As we indicated  in our  letter,  we are not at this time able
to make a categorical determination as to whether various types
of cans that may  have contained a wide range of products exhibit
the characteristic of reactivity.   It remains the responsibility
of the generator  of any particular waste to make this
determination  (see 40 CFR 262.11).  However, as we indicated in
the letter, a steel aerosol  can that does not contain a
significant amount of liquid (e.g.,  a can that has been punctured
and drained) would meet the  definition of scrap metal (40 CFR
2fl.l(c)(6)), and, if it is  to be recycled, would be exempt from
r  ulation under  40 CFR 261.6(a)(3)(iv).  Scrap metal that is
r -ycled is exempt from RCRA regulation under this provision even
if it is hazardous waste,  so generators need not make a hazardous
waste determination.   Scrap  metal that is not recycled, however,
is subject to the hazardous  waste regulations if it is hazardous,
so generators must make a hazardous waste determination.

     We appreciate your safety concerns and stress that persons
managing both regulated wastes and wastes that are exempt under
recycling exemptions  should  take all necessary precautions to
ensure that the wastes are managed safely.  Thank you again for
your interest in  this issue.

                               Sincerely,

1. K052: Bottoms from Tanks Storing
   Leaded  Gasoline  at  Petroleum
   Refineries

   According to 40 CFR §26132, the
hazardous waste code K052 applies to "tank
bottoms (leaded) from the petroleum refining
industry." A variety of petroleum fractions
including leaded gasoline are stored in
product tanks at refineries. Bottoms from all
of these tanks may contain lead. Does the
K052 listing apply only to bottoms from tanks
storing leaded gasoline, or does it apply to
lead-containing bottoms from refinery tanks
storing any petroleum fractions?

   EPA intended the K052 listing to apply
only to bottoms from tanks storing leaded
gasoline at petroleum refineries. The listing
does not apply to bottoms from tanks storing
other petroleum fractions, like diesel, even if
those bottoms contain lead.  Tanks bottoms
that do not carry the K052 code can still be
regulated under RCRA Subtitle C if they
exhibit one or more characteristics of
hazardous waste.

1.  Off-Specification  Paraformaldehyde
    Meets Commercial Chemical Product
    Listing

    A manufacturer stores product
formaldehyde (CAS No. 50-00-0) in containers
before use in a manufacturing process. While
in storage, some of the pure formaldehyde
polymerizes to form paraformaldehyde (CAS
No. 30525-89^1), which is unusable in the
manufacturing process because it does not
meet required specifications. The
manufacturer separates the paraformaldehyde
from the usable formaldehyde and sends the
off-specification chemical for disposal.
Unused commercial chemical products
containing formaldehyde are listed as U122
when discarded (40 CFR §26133(f)).
Paraformaldehyde is not found on the P- or U-
list (40 CFR §§26133 (e) or (f)). When
discarded, is the off-specification
paraformaldehyde a listed hazardous waste?

    In the above scenario, paraformaldehyde is
an off-specification form of formaldehyde and
meets the U122 listing (40 CFR §261.33(b)).
When a commercial chemical product listed in
§§261.33(e) or (f) undergoes a chemical
change that renders the chemical off-
specification, the applicable P- or U-listing for
the original chemical applies, even in cases
where the chemical composition has changed
sufficiently to require assignment of a different
CAS Number.

      MEMORANDUM

      Subject:  Regulatory  Status  of Wood Stickers Used For Wood
                Preserving  Operations

      From:     Rick Brandes, Chief
                Waste  Identification Branch

      To:       Jeff Ingalls, Inspector
                Oregon Department  of Environmental Quality

           This letter is in response to  your  request  that we make a
      regulatory interpretation as to the status  of discarded wood
      stickers which were used during wood preserving  operations.

           Wood stickers are typically used in wood preserving
      operations to separate bundled wood to ensure that more surface
      area of wood is  exposed during treatment.   Typically,  these
      stickers are reused for multiple wood treating operations.   When
      these wood stickers have reached their useful lifetime,  they are
      discarded, and it is  how these stickers  are disposed of which is
      the basis of this letter.

           Wood stickers which are disposed of by plants following wood
      preserving operations that use pentachlorophenol,  creosote,  or
      CCA are classified as listed hazardous waste for the following
      reason:  Drippage from wood  preserving operations that use
      pentachlorophenol, creosote, and CCA is  classified as  F032,  F034,
      and F035, respectively.  Wood stickers,  because  of their intended
      use, come in contact  with this drippage, thereby carrying the
      hazardous waste  code  when disposed.   The Agency  does not consider
      these stickers to be  treated wood product since  they are part of
      the process of treating the  wood.

           These stickers,  however, do not need to be  a part of a
      plant's monthly  hazardous waste reporting requirement  until  they
      are ultimately discarded since they are  being used as  a tool to
      treat the wood.

           If you have any  questions or comments  regarding this issue,
      please contact Mr. David J.  Carver  on (202)  260-6775.

Dear Mr. Kinne:

     Thank you for your  letter  dated July.l,  19,91,  requesting
clarification regarding  the  status  of  natural gas pipeline
condensate under Resource  Conservation and Recovery Act (RCRA)
regulations.  I apologize  for the long delay  in responding to
your request.

     As you correctly state  in  your letter, off-specification
fuels (such as natural gas pipeline condensate}  are not
considered solid wastes  under 40 CFR Part  261 when  burned for
energy recovery.  While  this interpretation has not been altered
since 1985, EPA has since  attempted to clarify what constitutes
legitimate burning for energy recovery and may have caused some
confusion as a result.

     The Agency addressed  the issue of legitimate vs.  "sham"
burning for energy recovery  in  the  February 21,  1991,  final rule
on Burning of Hazardous  Waste in Boilers and  Industrial Furnaces.
(56 FR 7134).  In the preamble  to that rule,  EPA cited burning  of
ignitable off-specification  natural gas condensate  as  a motor
fuel as an example of an inappropriate or  sham type of burning
for energy recovery.  The  Agency further stated that natural  gas
condensate, when used in this manner,  would be a solid and
hazardous waste subject  to Subtitle C  controls (see 56 FR 7184) .
EPA now recognizes, however, that this was a  poorly worded
example of what would be considered sham burning for energy
recovery.  A more precise  example,  and one that the Agency has
found to have occurred,  would be the sale  or  use of contaminated,
low energy value "natural  gas pipeline condensate"  as  a motor
fuel, or fuel additive  (such that additional  octane enhancers
also had to be added).

     In general, the January 4, 1985 preamble discussion you  cite
(50 FR at 630) still applies.   Accordingly, use of  unadulterated
natural gas pipeline condensate wit>> high  Btu/lb content as a
                                                         Printed on Recycled Paper

Suite 428
New York, New York 10110-0469

Dear Ms. Sahler:

       In your letter to Michael Shapiro of May 17, 1994 you requested EPA assistance in
determining the regulatory status of natural gas regulators that contain mercury under the Resource
Conservation and Recovery Act (RCRA).  You write that you believe that these regulators meet the
definition of a scrap metal.1  You also correctly point out that scrap metal is exempt from regulation
when reclaimed. 40 CFR §261.6(a)(3)(iii).  You have asked EPA whether natural gas regulators meet
the definition of a scrap metal so that NYGAS members would not have to manage these  materials as
solid wastes and hazardous wastes when sent for reclamation.

       EPA cannot concur with this interpretation.  Since your letter states that the natural gas
regulators contain mercury, these regulators cannot be scrap metal.  When EPA revised the definition
of solid waste in 1985, it created a new category of secondary material in the final rule, scrap metal.
50 FR  614, 624 (January 4,  1985).  In setting up this new category, EPA stated "Materials not
covered by this term include...liquid metal wastes  (i.e., liquid mercury) [emphasis added]...." 50 FR
at 624. The argument that the regulator taken as whole unit is mostly metal and does not contain a
"significant liquid component" is inapplicable here.  In general, any quantity of liquid mercury other
than trace amounts attached to or contained in a spent material precludes that material from being a
scrap metal.

       In addition, EPA agrees with the New York State position that used equipment of this type
cannot  be considered to  be a commercial chemical product.  Based on our understanding of this
material,  we believe that when removed from service, natural gas regulators containing mercury best
meet the  definition of a spent material.  40 CFR §261. l(c)(l).  Therefore, the regulators are solid
wastes  and hazardous wastes when sent for reclamation.  40 CFR §261.2(c)(3).  These natural gas
regulators would be subject to applicable RCRA Subtitle C regulations, 40 CFR Pans 262-265, 268
and 270.
               "Scrap metal" is bits and pieces of metal pans (e.g., bars, turnings, rods, sheets, wire) or
               metal pieces that may be combined together with bolts or soldering (e.g., radiators, scrap
               automobiles, railroad box cars) which when worn or superfluous can be recycled.  40 CFR

       Although these mercury-bearing natural gas regulators cannot be regulated as scrap metal, the
natural gas regulator may meet the definition of a scrap metal and be exempt from regulation once the
mercury component is removed from the regulator (provided it does not contain other liquids and
otherwise best meets the definition of scrap metal). Also, you may wish to consider petitioning the
Agency to include these regulators as part  of the proposed Part 273 Special Collection System
regulations when these regulations become final.  If included in the Part 273  regulations, these
regulators could be shipped under reduced Subtitle C  regulatory requirements (e.g., a manifest would
not be required). EPA requested comment on the potential usefulness of Part 2"f3 regulations to
mercury-containing thermostats in the proposed rule.  58 FR 8102, 8110 (February 11, 1993).

       Please be aware that under Section 3006 of RCRA (42 U.S.C. Section 6926) individual States
can be authorized to administer and enforce their own hazardous waste programs  in lieu of the
Federal program.  When States are not authorized to administer their own program, the appropriate
EPA Regional office administers the program and is the appropriate contact for any case-specific
determinations.  Please also note that under Section 3009 of RCRA (42  U.S.C. Section 6929) States
retain authority to promulgate  regulatory requirements that are more stringent than Federal regulatory
requirements.

       I hope that this letter sufficiently responds to your questions and concerns. If you have any
further questions or comments, please contact Paul Borst of my staff at (202) 260-6713.

Dear Mr. Shapiro:
                   The New York Gas Group ("NYGAS") wrote to you on December
                   22, 1993, to request your assistance with an issue under the
                   Resource Conservation and Recovery Act ("RCRA").

                   NYGAS has been working with the New York State Department of
                   Environmental Conservation ("NYSDEC") to determine the
                   appropriate classification under RCRA for natural gas regulators;
                   devices to reduce and regulate the flow and pressure of natural
                   gas to the consumer. As we-stated in our previous letter, some
                   natural gas regulators contain small amounts (approximately 2
                   ounces) of mercury to regulate the flow of natural gas. The
                   mercury is located in a small cup in the interior bottom of the
                   regulator.  The regulator itself is metal with some gasket and
                   diaphragm materials.

                   In our December 22 letter we noted that in  the past, NYSDEC had
                   characterized the regulator as a non-hazardous waste when
                   removed from service and had regulated the mercury  within as a
                   separate commercial chemical product.  This interpretation
                   changed, and in a letter to the Long Island  Lighting Company
                   dated May 7, 1993, NYSDEC concluded that when EPA published
                   its proposed "Universal Waste" rule in February 1993, "it became
                   apparent to us that this policy would be inconsistent with EPA's
                   position that the mercury in used equipment does not qualify as a

-------

commercial chemical product" and that "for the present we must consider used
equipment to be spent material, and subject to the hazardous waste regulations
whenever the unit fails the Toxicity Characteristic."

In our previous letter, we asked whether EPA would allow NYSDEC to reinstate the
earlier policy of regulating the mercury as a commercial chemical product. We also
brought to your attention an alternative approach adopted by USEPA Region I that the
used, but still functional equipment is not a "spent material".

After further discussions with NYSDEC, we have concluded that there is an approach
in the regulations which allows the members of NYGAS to reclaim the regulators
without having to manage the equipment as  hazardous waste, and which also avoids
the necessity of deciding whether the regulators are "spent" or if the mercury within
the regulators qualifies as a "commercial chemical product."  Specifically, the
regulators qualify as "scrap metal" within the meaning of 40 CFR §261.1(c)(6) (and the
comparable NYSDEC definition) and are exempt from regulation when reclaimed
pursuant to 40 CFR§261.6(a)(3)(iv).

By definition the category of scrap metal encompasses manufactured metal goods
such as radiators, automobiles and railroad box cars, 40 CFR §261.1(c)(6), and  the
definition has been applied to other manufactured goods, such as used naval
torpedoes (reference letter dated February 25, 1986 from Marcia Williams to Christian
Valz [9441.1986(14)]). "Put another way, scrap metal is defined as  products made of
metal that ...are recycled to recover their metal content." 50 Fed Reg. 614, 624
(January 4, 1985).  Wastes consisting entirely of liquid metals, such as mercury, or of
products with a significant liquid component,  such as spent batteries, are not regarded
as "scrap metal" (50 Fed. Reg. 624); however, metal products which do not contain
large amounts of liquid are regarded as scrap metal. Automobiles are a prime
example.  Scrap automobiles contain oil and other automotive fluids as well as non-
metallic materials, nevertheless, an automobile is defined as "scrap metal".

Natural gas regulators are  metal products (approximately 15-20 pounds) which contain
some non-metallic parts and a small amount of liquid mercury (approximately 2
ounces). Based on the precedent established with respect to automobiles, radiators,
torpedoes and other metal  goods and equipment, we believe the used regulators are
"scrap metal" and are presently exempt from regulation in accordance with 40 CFR
§261.6(a)(3)(iv).

Thus, even assuming the used regulators are a "spent material" which exhibit a
characteristic of hazardous waste due to the presence of mercury, and that the
mercury has lost its status  as a "commercial  chemical product",  the regulators are
scrap metal which are not currently subject to regulation.

-------
Mr. Michael Shapiro

NYSDEC has indicated to us that it may be willing to apply the State's comparable
exemption for recycled scrap metal to pur situation,  if NYGAS obtains confirmation
from EPA that the regulators would qualify as scrap metal under the Federal
regulations.

In lieu of a response to our letter of December 22, 1993, the members of NYGAS
urgently request your immediate assistance in this matter in order to eliminate the
uncertainty inhibiting the replacement of our equipment.

Please feel free to call me at 716-724-8684 with any questions or concerns; I look
forward to receiving your written response.  Thank you in advance for your time and
assistance.

Mr. Mark Veckman
Comprehensive Environmental Assessments
8662H Lee Highway
Fairfax, Virginia 22031

Dear Mr. Veckman:

     This letter addresses  the questions raised in your Freedom  of
Information request  of March 11,  1994.   You requested information
on the applicability of information provided in 1990 by EPA Region
V to the State of Ohio.  The issue centered on the status of wastes
generated from  abatement of lead-based paint (LBP).

     Since  the  enactment of  the Residential  Lead Paint Hazard
Reduction Act  of  1992 requiring the elimination   of  lead paint
haz'ards to children, there  has been a significant increase in the
generation of  LBP waste.   Several  federal agencies,  States, and
advocacy groups have  raised concerns about  the effect  the RCRA
hazardous waste management regulations may have on residential LBP
abatements.  The Agency is currently evaluating  various disposal
alternatives    for   LBP   waste   resulting    from   abatement,
rehabilitation,  and  demolition.   EPA may  amend the existing RCRA
regulations  or may  propose different rules  governing  LBP waste
disposal.

     In response to  your  specific request  on  the applicability of
household waste exemption under RCRA to the disposal of LBP waste,
we have  reviewed the  information contained in the  September 12,
1990 letter  from EPA  Region V.   Disposal  of LBP waste  has been
subject to RCRA Subtitle C since 1980 and  some LBP wastes may be
hazardous due   to  Toxicity Characteristic  for lead (see  40 CFR
261.24).  In the preamble to a Federal Register notice addressing
this issue  (49  FR 44998, November  13,  1984,  copy  enclosed), EPA
discusses the  limited  scope  of  the RCRA exemption  for household
wastes.  This notice indicates that the EPA Region V letter should
be clarified on the  following key points.

     Household  waste,  to be  excluded pursuant to 40  CFR Section
261.4(b)(l)  must fulfill two criteria:  first,  household waste has
to be generated by individuals on the premises of a household and,
second, "the waste stream must be composed primarily of materials
found in the  waste generated by  consumers in their homes."   LBP
waste from construction,  demolition,  or renovation  does  not meet

                                                     Ffeeyeted/Recyclabl*
                                                     Prtnt»d with Soy/Candi Ink on p«p*r iiut
                                                     contain* tt l««*t 60% recyeiM flb*r

-------
these two criteria.  Therefore,  these wastes are not excluded from
RCRA Subtitle C as household waste.

     EPA  does  not  distinguish  between waste  generated  at  a
household by a homeowner  and waste generated  at  a household by a
person other than  the  homeowner (e.g.,  contractor) provided that
the waste  is generated  as part  of daily living  (e.g.,  routine
residential  maintenance).   Under EPA's  current  reading  of  the
household waste exemption, LBP  waste is not  similar to the waste
typically generated by household (e.g.,  household trash comprising
of discarded consumer goods),  and should, therefore, be evaluated
for its potential to be RCRA hazardous waste.  However, solid waste
generated by a homeowner,  resident,  or  a contractor at a home as
part of  routine  residential  maintenance  (as opposed  to building
construction, renovation,  and  demolition) would  be part  of  the
household waste stream, and thus  would  be covered under the RCRA
household waste exemption.

     LBP waste  that  is  hazardous  (i.e., exceeds the  toxicity
characteristic limit  of 5 ppm  for  lead in  waste  leachate),  if
generated in small quantities  (i.e., less than 100 kg per month of
hazardous waste),  may be  exempted from  RCRA  Subtitle C  as  the
conditionally exempted  small  quantity  generator waste,  if State
programs provide  the federal exemption.   Nearly all  States  are
authorized to implement the RCRA  program. Therefore,  you should
contact the State waste management agency where the  LBP waste would
be generated and disposed, for  further  assistance in determining
the appropriate waste management and disposal requirements.

     If you have any other questions on this  issue,  feel free to
call Ms. Rajni Joglekar of my staff at  202-260-3516.

 Director of Environmental, Safety & Governmental

 Dear Mr. Rhodes:

        This letter is in response to your March 9, 1994 letter in which you requested a
 regulatory interpretation regarding photoresist solids ("skins") generated in the printed circuit
 board manufacturing industry.  You asked for a decision as to whether these wastes are  or
 are not F006 HSU.U hazardous waste.  This longstanding issue arose originally when the
 Virginia  Department of Environmental Quality asked EPA's Region III office for assistance
 in making a site specific hazardous  waste determination at a printed  circuit board
 manufacturing facility in Virginia.

        We have reviewed the data available to us, including the State and  Regional
 interpretations you have provided, and have conducted further analyses of  the manufacturing
 processes involved. Based on this review, I have made the  following determination
 regarding the status of photoresist solids.

        For the reasons stated below, we cannot categorically state that photoresist solids
 generated in stripping operations are not F006 wastes- Their regulatory status is dependent
 on the type of operation employed at each individual facility.  Therefore, the determination
 as to whether or not skins are hazardous waste will be dependent on the analysis of the
 individual facility by the State or Regional regulatory authority. Regulatory authorities
 should  make this determination based on the following interpretation of the F006 hazardous
 waste listing description:

 o      The crux of this issue is whether the stripping of photoresist solids  from printed
        circuit boards is an electroplating operation included  within the scope of the F006
        listing as defined  by the Agency in the Interpretative Rule on this subject which was
        published in the Federal Register on December 2, 1986 (51 FR 43350).  Please note
        that although the printed  circuit board manufacturing industry is no longer specifically
        identified in the F006 listing as a result of the December 2, 1986 interpretive rule (51
        FR 4"3350), the processes used (e.g., electroplating, chemical etching,  and cleaning
                                                                        Recycled/Recyclable
                                                                        Printed with Soy/Canoli Ink on paper mat
                                                                        contains «least 50% recycled liber

-------
       and stripping) may'still cause wastewater treatment sludges to meet the  F006 listing.
       The interpretive rule was merely a correction to reflect the Agency's policy of
       referring to "processes"  only, rather than specific industries in the "non-specific
       source" F listing the notice did not otherwise change the scope of the  listing with
       respect to the printed circuit board industry.  This was also explained in the attached
       memorandum fmm Sylvia K. Lowrance, Director, Office of Solid Waste, to Ted A.
       Hopkins  of the Oregon Department of Environmental Quality.

       If stripping solutions are within the scope of the listing and are, therefore,
       electroplating wastewaters, the filtering of skins from that solution should be
       considered the generation of wastewater treatment sludge from electroplating
       operations and thus would be considered F006 listed hazardous wastes.  If stripping
       solutions are not electroplating wastewaters  then the skins would not be wasrr.vater
       treatment sludges and thus not  F006.

o      Because the "cleaning and stripping" subcategory of electroplating operations is a
       conditional one (cleaning and stripping operations are only defined as electroplating
       operations when they are associated with common and precious metals electroplating,
       anodizing,  or chemical etching and milling operations), and because there has not
       been specific guidance issued as to when there is a strong enough "association"
       between a cleaning and stripping operation and another included process, we are
       issuing the following determination as to when a cleaning or stripping operation is
       defined as an electroplating operation for purposes of the F006 listing:

              If the stripping operation is in line with or contiguous  with an electroplating
              operation, then the stripper solution itself becomes an electroplating
              wastewater. "In  line with  or contiguous with" in  this case would mean the
              stripping operation is not physically separated from these operations and the
              printed circuit boards are not rinsed and dried prior to the photoresist stripping
              operation.  The stripper solutions thus could be mixed or intermingled with
              electroplating wastewater.

              Photoresist solids generated in this case would be  F006 wastes.

              If the stripping operation is not in line with or contiguous with an
              electroplating operation the stripping solution itself does not become an
              electroplating wastewater.

              Photoresist solids generated in this case would not be F006 wastes.

       The rationale for this interpretation is based on the intent of the listing of F006
wastewater treatment sludges.  F006 hazardous wastes were listed for reasons explained in
the November 14, 1980 RCRA Background Document for  listed hazardous wastes.  Among
the reasons was  the  conclusion that these wastes frequently contain cadmium, hexavalent
chromium, nickel, and complexed cyanide in significant concentrations.  The listing process
is designed to insure that wastes which meet the listing criteria are managed as  hazardous

-------
wastes.  (Please note that wastes which meet the listing description but do not contain the
constituents or do not exhibit the properties  for which they were  listed can petition the
Agency or authorized State for a site-specific exclusion).  If there is any possibility of skins
stripping solutions being mixed or commingled with other electroplating  wastewater,  or if the
hazardous constituents generated by other electroplating processes can otherwise be "carried
forward" by the nature of the association of the two processes, the skins themselves cc-'.d
become contaminated with these hazardous constituents.

       Our analysis suggests that physical separation of the two operations together with
rinsing and drying operations of printed circuit boards prior to stripping  serve to prevent the
carryover of potential hazardous contaminants from the electroplating and etching operations
to the stripping operation.

       Conversely, our analysis suggests the lack of separation and rinsing and drying
operations  can result in the carryover of wastew-uer from the electroplating processes into the
stripping solution. In these cases, the filtering of the skins from the contaminated stripping
solution would constitute treatment of an electroplating wastewater and would result in the
generation of F006.

       Although skins may in some cases  be determined to not be F006 listed hazardous
waste under federal regulations, the skins  may be subject to more stringent state or local
regulations.  However,  even if the skins do  not meet the listing description for federal or
state regulations,  they are  still subject to evaluation for hazardous waste characteristics, as
specified at 40 CFR Part 261 Subpart C.

       The Agency  may revisit this issue at  a  later time based on new information or facts
which it  may  gather.

       Thank you for your patience in this matter.  If you have any further questions, please
contact Rick Brandes of my staff at (202)  260-4770.

In addition, the I PC has collected TCLP data from more than 20 companies on their photo-
resist skins and solid residues. AH samples passed the TCLP test. None showed toxicity
characteristics high enough to be classified as characteristic hazardous waste. In order to
properly monitor and control the filtered skins, IPC encourages all of its members to
conduct periodic TCLP testing on the skin residues. We feel that these photoresist skins are
already properly regulated through the present TCLP testing  regimens.

Despite letters and supporting data from the IPC (enclosed) and state EPAs as well as
extensive communication from OuPont and other photoresist suppliers, we have still
received no written clarification or resolution of this issue from the Federal EPA office. As a
result, the Region III interpretation has caused industry-wide confusion and is increasing
waste handling costs for circuit board manufacturers without yielding any environmental
benefit. Capturing non-hazardous photoresist solids  under the RCRA F006 classification
greatly increases manufacturing costs while using up precious hazardous waste landfill
capacity that is needed for genuine hazardous waste.

If the Region III ruling is allowed to stand, it could add up to  10  million pounds annually to
the national hazardous waste stream. This unnecessary and costly expense would further
reduce the competitiveness of an industry already hard pressed  by foreign competitors
operating under less stringent environmental and safety regulations.

While waiting for a response from your office, a number of IPC member companies or
regional circuit associations have proceeded with seeking interpretations from the state and
local authorities. We have enclosed copies of all such rulings received to date. Thus far,
every single state ruling has contradicted the  Region III interpretation.

For these reasons, we feel that the Region III  decision is clearly  erroneous and should be
overturned by  your office. We respectfully ask that you please expedite resolution of this
issue at your earliest convenience. If you need additional information or have  questions, we
would be happy to discuss this issue and answer any questions at your convenience.

Thank you for  your time and consideration.

                               Chronology of Appeal on Resist Skins

   • June 16, 1992 - DuPont letter  to U.S. EPA asking for clarification on why resist stripper skins
   and sludge were classified as F006 classification, based on industry data that there were no
   hazardous materials in the skins and sludge.

   • July 2, 1992 - IPC letter on behalf of the industry was sent to Sylvia Lowrance, USEPA, asking
   that a clarification and reconsideration be made onof EPA Region III decision on F006 classification
   for photoresist skins.

   • Feb. 3, 1993 - Meeting between EPA Chief of Waste Identification Branch, Rick Brandes, and his
   staff with DuPont representatives and their lawyer. EPA asked for additional information to confirm
   the contention that PWB manufacturers do not intentionally allow metals into their stripper solution
   in order to dispose of them. EPA indicated at the  time that Federal EPA was in agreement with at
   least the skins NOT being F006, but would need some time to "mend their fences with the regions".
   Nothing was put into writing.

   • August 2,1993 - letter sent to EPA by DuPont with arguments answering questions raised at the
   February meeiting, among them were ones showing that the metal concentration  in strippers were
   not being used as a method of disposal for metals.

   • December 6, 1993 - DuPont spoke to Rick Brandes by phone to find out what had been done with
   respect to the F006 issue. Mr. Brandes  indicated  that there were still problems with some of the
   regional EPAs as to their interpretation. DuPont indicated that Minnesota had decided that both
   skins and sludge were NOT F006 and give Mr. Brandes the name of the EPA official who had been
   sent the Minnesota information.

   • January 24,1994 - DuPont discussed the problem with Mr. Gregory Helms (Chief, Characteristic
   Section - Waste Identification Branch) who was standing in for Mr. Brandes at the AESF/EPA
   convention in Orlando. Mr. Helms indicated that Region HI was still not cooperating with
   Washington EPA on the interpretation. Mr. Helms said that another follow-up letter might help.

   • February 3,1994 - DuPont sent a follow-up letter to Mr. Brandes - reiterating all the above,
   indicating that the Minnesota state EPA had found that the material are not F006, and that the
   interpretation was causing the industry an unnecessary expense and loss of competitiveness. A copy
   of the letters from Minnesota and Midwest Circuits Association was included.

   • March 1,1994 -  We met with Mr. Brandes, but were unable to reach a resolution of the skins
   issue.

Reference:     Applicability of Hazardous Waste Codes to the LASER
               EX  chemical  polishing system

Dear Mr. Tease:

     This responds to  your  letter dated June 15, 1994,  requesting
an interpretation of the potential applicability of hazardous waste
codes to your process  for chemical polishing.

     It  is  our understanding, that  LASER EX  is a peroxide-based
chemical polishing system, which entails  the chemical  oxidation of
the surfaces  of  brass and  copper alloys as  the final step after
production  and  prior  to   plating,   lacquering,  antiquing,  or
assembly.   Specifically the  process  dips parts to  be chemically
polished in an oxidative chemical bath.  The actual process entails
an aqueous wash followed by a sulfuric  predip, the LASER EX bath,
and a  sulfuric acid post dip.  A cold water  rinse  is performed
between  each  step.     The   process   reportedly  does  not  employ
electroplating or  use  cyanides.

     Based on the information you have provided us,  the  process
does  not employ  electroplating  or  the  use  of cyanides and is
separate  and  distinct from  any  such  operations.    such  process
wastes are not within the scope of the wastes  listed in 40 CFR Part
261  Subpart  D.    However,  solid  wastes which are  not  listed
hazardous wastes in 40 CFR Part 261 Subpart D, may also be classed
as hazardous wastes, if they exhibit any of the characteristics of
a hazardous waste  found  in  40 CFR 261 Subpart C.

     For example,  based  on  the reported compositions of the baths
it is possible for waste baths or rinses  containing sulfuric acid
to  exhibit the  characteristic  of corrosivity  (40 CFR 261.22).
Aqueous wastes which have a pH less than  or  equal to 2 or greater
than or equal  to  12.5 must be managed as EPA Hazardous Waste Number
D002.   In the case  of the LASER  EX  bath and  subsequent  washes,
these  waste   baths  and   subsequent  rinses   may   exhibit  the
characteristic of  ignitability and would require management as EPA
Hazardous Waste Number D001 (40  CFR  261.21).   This is because the
bath contains  the  inorganic oxidizer hydrogen  peroxide, which is
capable of severely exacerbating  a fire once  started by yielding
                                                     Recycl«d/R«cyclabl«
                                                     Printed with Soy/Canola Ink on paper that
                                                     contains at least 50% ntcycitd fiber

-------
oxygen to  stimulate  the combustion of organic  matter.   Once the
hydrogen peroxide has been chemically decomposed, the wastes would
no  longer exhibit  the  ignitability characteristic  due  to  the
presence of an oxidizer.  Wastes which are hazardous because they
exhibit  one   of  the  40  CFR 261  Subpart  C characteristics  of
hazardous  waste  remain hazardous and subject to  the regulations
governing hazardous waste management,  until  they no longer exhibit
the characteristic.  However, as  stated in the final sentence of 40
CFR 261.3(d) (1),  "wastes that exhibit a characteristic at. the point
of generation may  still  be  subject  to the requirements of 40 CFR
Part 268,  even if  they no longer exhibit a  characteristic at the
point of disposal."

     The above discussion is limited to hazardous waste codes which
are  most  likely  to  be  produced  in the LASER  EX  process,  as
described to us.  This in no way limits the obligation of any waste
generator to fully characterize solid wastes being generated (see
40 CFR 262.11) and to manage such wastes in accordance with all
applicable  federal  or  state  regulations.    States  may  impose
regulations more stringent  than  the  federal program.  Therefore,
you  should also  consult the local RCRA  regulatory authority for
where the process is  to be utilized.

Dear Mr. Shapiro:

I am writing you to request a ruling on the waste classification of a
new chemical  process.   We  have named our newest chemical
polishing system the Laser EX;  it is based on hydrogen peroxide and
a stabilizer package.  The polish  is intended for use on brass and
copper  alloys.  I have already met with Max Diaz on the line, his
initial response was that the waste should not need to be classified as
long as the sludge produced in waste treatment passes a leech test. I
have given him much more information than  I can include in this
short letter.

The Laser EX process is very simple. It involves an aqueous clean, a
sulfuric predip, the Laser dip step, and a sulfuric acid post dip.
There is cold water rinses in between each step; it is the waste that is
carried  over into these rinses that we need the ruling on.  I have
included with this letter a product data sheet and an  M.S.D.S. for
more information.

Unlike most peroxide based systems, this system does not etch the
surface.  Rather, it oxidizes the surface to form a protective brown
copper  oxide coating over the alloy.  When we remove  this dark
brown oxide film a bright, leveled, and very  clean surface is the
result.  Some examples of where the Laser EX may find uses is as the
final step after production prior to plating, lacquering, antiqueing, or
assembly. Laser can take the place of hand buffing which leaves a
very difficult soil to clean off the  part.  The Laser EX is also a good
replacement for strong acid mix bright dips. There is no chance that
there will be water carried over into this step from a plating solution.
Laser EX does not use any electrical current for brightening. It may

not effect your ruling but the system uses no chelators, cyanides,

MEMORANDUM

SUBJECT:   Classification of Discarded Ammunition of 0.50 Caliber or Less

             Alternative Technology Section (5303W)
             Office of Solid Waste

TO:          David Neleigh,  Chief
             New Mexico/Federal Facilities Section (6H-PN)
             Region VI

       This is in response to your request of June 14, 1994 in which you ask  for a
clarification of EPA's policy regarding the disposal of munitions less than or equal to 0.50
caliber. EPA's policy was set forth in a June 2,  1988 memorandum on Classification of
Discarded Class C  Explosives.

       In that June memorandum, EPA stated "To date, only those Class C explosives
identified as off-specification small arms ball ammunition up to and  including  0.50 caliber
have been demonstrated not to be subject to the Subtitle C hazardous waste requirements."
However,  EPA did not intend to imply that small arms ball ammunition could not be
regulated for  reasons other than reactivity.  The Agency has maintained that small arms
ammunition intended for disposal, up to and including 0.50 caliber,  is not reactive within the
meaning of 40 CFR 261.23(a)(6).  The sole fact that small caliber ball ammunition is not
reactive does  not necessarily exempt the waste  from Subtitle C regulation.  Non-reactive
wastes exhibiting another hazardous waste characteristic would be  regulated.  For example,
certain small  caliber ammunition may fail  the TCLP for lead.  Generators of discarded small
caliber ammunition must determine whether their waste exhibits any other hazardous waste
characteristics identified in §261 Subpart C.

       Your memo also describes an instance where a waste is disposed of in  a popping
furnace "that  does not fit the description of an incinerator and the  munitions are less than or
equal to 0.50 caliber, then this would not be regulated under Subtitle C ..." You are  correct
in that a device treating discarded ball munitions less than or equal to 0.50 caliber, would not
be subject to  Subtitle C regulations, unless the  waste fails for another characteristic rendering
it hazardous.  However,  please note that EPA classifies  "popping furnaces"  as incinerators
because the process  that occurs in the enclosed unit is controlled flame combustion, as
discussed in the attached July  17, 1987 letter from Bruce Weddle to Jesse Cabellon.

Mr. Charles D. Duthler
ICI Composites, Inc.
2055 East Technology Circle
Tempe, AZ 85284

Dear Mr.  Duthler:

       This is in response to your letter of July 12, 1994, concerning the characterization of
waste streams from polymeric coating operations.  You stated that you are working on a
project to  ensure that waste streams from polymeric coating operations are properly
characterized and you ask several questions related to these waste streams.  We have
addressed  your questions in the discussions below. In some cases, the determinations you
seek are based on site-specific factors and are best made by the appropriate regulatory agency
(i.e., State, or EPA Region implementing the RCRA program for a particular State).
Where applicable, we have provided general information  to assist you in making your
determinations, but we  recommend that you contact other more appropriate offices for the
determinations you seek.

1. How does a generator determine if his/her equipment qualifies as  a manufacturing process
unit?
       As you have noted, the preamble language at 45 FR 72025, October 30, 1980,
describes examples of manufacturing process units.  These include "...distillation columns,
flotation units, and discharge trays of screens..."  The preamble language also describes
these units as "tanks, or tank-like units (e.g., distillation units) which are designed to hold
valuable products or raw materials in storage or transportation or during manufacturing."
(45 FR 72025, October 30,  1980)  A determination of whether the units you describe are
manufacturing process units is best made by the regulatory agency (i.e., EPA Region or
State)  implementing the RCRA program in the area of operation.  In addition, States with
authorized programs may impose more stringent requirements. For these reasons,
consultation with the State in which polymeric coating operations will take place is
recommended.

2. If an ignitable residue is removed from a unit with a wiper, does the resulting  waste
carry  the ignitability characteristic, or is the contaminated wiper to be evaluated to determine
if it exhibits the characteristic?  How does the mixture rule apply to  wipers used to clean
hazardous wastes?
                                                                    contain* M !••« 50% fteyet«d flbtf

-------
       A material that is a solid waste is by definition hazardous waste if it either 1) meets
one of the listings in 40 CFR Part 261, Subpart D, or 2) exhibits one or more of the
characteristics described in 40 CFR Part 261, Subpart C.  Because there are no explicit
listings for "used wipers"  in Part 261, Subpart D, a wiper can only be defined as listed
hazardous waste if the wiper either contains listed waste, or is otherwise mixed with
hazardous waste. Whether or not a. used wiper contains a listed hazardous  waste, is mixed
with listed hazardous  waste, only  exhibits a characteristic of hazardous waste, or is not a
waste at all,  will require  site-specific determination.  Any  determinations  or interpretations
regarding this diverse and variable waste stream should be made by the  appropriate State or
EPA Region.  We have enclosed a memo from Michael Shapiro to EPA Regional Waste
Management Division Directors dated February 14,  1994, on the subject of industrial wipers
and shop towels for your information.

3. What is the status of the proposed rule amending SW-846 to identify  the technique suitable
to determine if a material  contains a liquid for an ignitability determination?

       The proposed rule  is  still undergoing Agency review.  Promulgation of the Agency's
final ruling should occur in early  1995.  In the interim, the Paint Filter test is the method to
use to determine if a free liquid is present for ignitability determination.

4. How does a generator determine if his/her wastes exhibit the potential for spontaneous
combustion?

       No test method has been promulgated for "spontaneous combustion".  It is the
generator's responsibility to  compare the properties of his waste with the narrative definition
at 40 CFR §261.21(a)(2) and determine  if the waste poses a hazard if improperly disposed.
Also be aware that the U. S. Department of Transportation, at 49 CFR  §173.124{b),
discusses "spontaneously combustible material" and describes a Test Method for Materials
Liable to Spontaneous Combustion in 49 CFR Part 173 Appendix E.

       I hope this letter is of assistance. If you have further questions,  please contact  Ann
Codrington at (202)260-4777, or Oliver Fordham at (202)260-4778.

Dear Mr. Goodwin:

     Thank you for your letter of October 3,  1994  requesting
information  about  policies regarding self-certification of non-
hazardous waste.

     Policies  do exist for self-certifying that  some types of
waste are non-hazardous but not for others.

     If waste  is not "listed" nor derived from a "listed"
hazardous waste it would be hazardous only due to  characteristics
at 40 CFR 261,  Subpart C.  In this case, a generator may either
test the waste or  use knowledge to determine  that  it does not
exhibit one  of the regulatory "characteristics"  in 40 CFR 261 and
thus is not  a   hazardous waste.

     If the  waste  is "listed" or derived from a  "listed"
hazardous waste, that is, if it appears on one of  the lists in 40
CFR 261, Subpart D,  then the generator cannot currently self-
determine that a treated or mixed waste is no longer hazardous.
Instead, they  must petition EPA to remove their  waste under 40
CFR Sections 260.20 and 260.22.  The waste is regulated until EPA
grants the petition.  All of this is true whether  the waste is to
be disposed  of, or beneficially recycled, although EPA has
certain special exemptions in 40 CFR 261.2(e), 261.4, and 261.6,
for certain  kinds  of recycling.

-------
     EPA is currently developing a procedure by which listed
wastes can also be self-certified as no longer hazardous.  That
rulemaking is referred to as the Hazardous Waste Identification
Rule.  We expect proposal of this rule to be published in the
Federal Register by fall, 1995.

     Thank for your interest, ana I apologize for the delay in
responding to your inquiry.

                              Sincerely yours,

Reference:        Clarification of F006/F019 Interpretive Letter
Dear Mr. Wozniak:

      This letter is in response to your request for further clarification of our
October 20, 1994 interpretive letter in reference to wastes generated from your
aluminum coating process.  The following is the revised version of the letter,
reproduced here for future reference purposes. This action is being taken because
the phrase "metal salts" was inadvertently included in the original letter and is
irrelevant with respect to the intent of the listing.

      Your process consists basically of three unit operations which are described
below,  together with  a discussion of the relevant hazardous waste listing
descriptions:

o     The aluminum is first anodized in sulfuric acid.  The F006 listing description
      (40 CFR 261.31) specifically excludes wastewater treatment sludges from
      sulfuric acid anodizing of aluminum.

o     The anodized material is next sealed and colored by immersion in solutions
      of inorganic or organic colorants.  Neither ferrocyanide nor chromate-
      containing solutions are  used in this coloring process.  The material is finally
      coated  by electro-deposition with a clear acrylic film.

      Based on the information you provided us, these processes apparently do
not involve the use of chromates or cyanides; thus, any wastes generated from this
process do not satisfy the descriptions  of F006 or F019.  Additionally, since these
processes are not identified in  any of the specific or non-specific source hazardous
waste listings in 40 CFR Part 261,  Subpart D, any wastes generated from this
                                                              Recycfedftecyclabie

process would only be subject to evaluation for hazardous waste characteristics, as
specified at 40 CFR Part 261  Subpart C.

      Please be aware that under Section 3006 of RCRA (42 U.S.C. Section 6926}
individual States can be authorized to administer and enforce their own hazardous
waste programs in lieu of the Federal program. When States are not authorized to
administer their own program, the appropriate EPA Regional office administers the
program and is the appropriate contact for any case-specific determinations.
Please also note that under Section 3009 of RCRA (42 U.S.C. Section 6929)
States retain authority to promulgate regulatory requirements that are more
stringent than Federal regulatory requirements. Although this interpretation
indicates that the wastes generated from the above processes are not subject to
the hazardous waste listings under federal regulations, the wastes may therefore
be subject to more stringent state or local regulations.

questions, please contact Max Diaz of my staff at (202) 260-4786.

Dear Mr. Wozniak:

     This letter is  in response to  your letter of November 24,
1993, outlining  your aluminum coating process, and inquiring if
any of the wastes generated meet the  hazardous waste listing
descriptions for F006 or F019 published at  40 CFR 261.31.  We
have consulted with  Mr.  Jeffrey T.  Pallas,  Hazardous Waste
Management Branch, U.S.  EPA Region  IV and Ms. Renee Hudson

Dear Ms. Adler:

       I am writing in response to your May 10, 1995 request for an interpretation of 40 CFR
261.32 with respect the scope of EPA Hazardous Waste No. K052 ("tank bottoms Geaded) from
the petroleum industry"). Specifically, you inquired whether or not tank bottoms removed from
tanks containing only naphtha would be deemed to be K052 hazardous wastes.

       The scope of the K052 hazardous waste listing is limited  to only those tank bottoms
generated at or as part of a petroleum refinery from tanks employed in the storage of leaded
gasoline or leaded blending fractions.  These tank bottoms are covered by the K052 hazardous
waste listing even if they do not exhibit any other characteristic of a hazardous waste.

       Naphtha is  an unleaded petroleum fraction isolated for blending or production of other
blending stocks. The tank bottoms from only naphtha storage at a refinery would not be a listed
hazardous waste under 40 CFR 261.31, and would not otherwise be subject to regulation as a
hazardous waste unless they exhibited one  of the characteristics  of a  hazardous waste, as
provided for in 40 CFR 261.21 - 261.24.

       Please note that under section  3006 of RCRA, individual  states can be authorized to
administer and enforce their own hazardous waste programs in lieu  of the  Federal program. In
addition, section 3009 of RCRA allows states to promulgate regulatory requirements that are
more stringent than the Federal program.  Therefore, you should contact the appropriate state
environmental agency in your state for other applicable laws and regulations that may exist.

       If you have any further questions, please contact John Austin at (202) 260-4789.

                                        Sincerely,

              Re:  Request for Rule Interpretation

   Dear Mr. Shapiro:

              We  are  herewith  requesting that the U.S.  Environmental
   Protection   Agency   (the   "EPA")   provide   to   us  a   written
   interpretation of 40 CFR §  261.32 with respect to the scope of the
   EPA Hazardous Waste No.  K052  ("tank bottoms  (leaded)   from the
   petroleum industry") .   Specifically, are tank bottoms removed from
   tanks containing naptha deemed to be K052 hazardous wastes, if the
   tanks have never held leaded gasoline?

              Doug of the EPA RCRA Hotline  informed  me on May 9, 1995
   that,  pursuant to a  February,  1994 oral interpretation by the EPA,
   K052 refers only  to  tank bottoms from tanks  that have held leaded
   gasoline. _. We are seeking a written rule interpretation so that we
   may  properly  advise  our  clients  of  any  federal  requirements
   applicable to the disposal of naptha  tank bottoms.

              Please  telephone me if you  have any questions.

Meriden,  CT  06450

Dear Ms.  Tucker:

      This is in response to your February 20, 1996 letter regarding the waste
characterization of the unused chemical "potassium hexacyanocobalt (II) -
ferrate (II)," and of the spent material that results after use of that
chemical  for the selective removal of Cs-134 and Cs-137.  In particular, you
ask for the  Agency's assessment of whether or not the spent material would be
considered a hazardous  waste and hence a mixed waste (hazardous and
radioactive).

      A solid waste is  considered hazardous if it is either listed or  fails
one of the four "characteristics"  (40 CFR 261}, assuming it has not been
otherwise excluded  from the definition of hazardous waste.  Neither the unused
product nor  the spent material you describe in you letter is a. currently
listed hazardous waste  and, based on the analysis provided, neither appear to
exhibit any  of the  characteristics of a hazardous waste (40 CFR 261.20) .
Based upon the Agency's assessment of the physical properties of the
hexacyanocobalt(II)-ferrate(II) ion-exchage media, it also appears unlikely
the media would exhibit the characteristics of a hazardous waste.  Therefore,
the unused discarded potassium hexacyanocobalt (II)-ferrate (II) product or
spill residues thereof  would not be RCRA hazardous waste.

      However,  if 40  CFR 261.24 toxicity characteristic constituents are
present in the wastes being treated, then there is some potential for the
spent ion-exchange  media to become a hazardous mixed waste.  In general, the
Agency would not expect spent hexacyanocobalt(II)-ferrate(II)  ion-exchage
media to  become characteristically hazardous due to contaminants adsorbed
during the treatment  of Cs-134 and Cs-137 bearing waste streams.  However,
this eventuality cannot be assessed fully without knowledge of the
characterization of the waste stream to be treated.  It is the responsibility
of the waste generator  to  determine whether or not a waste is hazardous (40
CFR 262.11)  by either testing the waste or by applying knowledge of the hazard
characteristic of the waste in light of the materials or the processes used,
and to dispose of the wastes in compliance with all applicable regulations.

      If  you have further questions concerning mixed waste, please contact
Nancy Hunt at (703)  308-8762.  If you have questions regarding hazardous waste
characteristics,  please contact John Austin at (202)260-4789.

Dear Sir.

        On November 17,1995, nay colleagues and I visited staff members in your office to discuss the
waste characterization of a chemical which we intend to import from Finland. This chemical. Potassium
cobalt hexacyano ferrate, is a black granular media resembling ground charcoal.  Its intended use, as
expressed in our low level exemption of our PMN, will be the selective removal of Cs-134 and Cs-137
from various liquid waste streams.

        Our media has a strong affinity and enormous capacity for Cesium removal. The
decontamination factor (DF) is two orders of magnitude greater than any other media currently available.
The resulting volume .reduction of solid radioactive waste is equally huge by comparison. We have
recently demonstrated, for example, that Callaway Nuclear Plant in Fulton, MO would need to bury 9 cu.
ft of our media instead of  375 cu. ft. of the "next best" ion exchanger to remove cesium from the same
volume of water.

        The use of this chemical would be prevalent at nuclear plants and for U.S.D.O.E. cleanup efforts
at sites such as Hanford. When the media eventually becomes chemically exhausted, it must be buried in
a high integrity container (HIC) at an approved radioactive waste burial site such as in Bamwell, SC.

        Our concern has been the detrimental effect a hazardous waste characterization under RCRA
might cause. If characterized as hazardous, the resulting spent media would be a mixed waste (hazardous
and radioactive) and undisposable at current burial sites. Concerns expressed by potential clients has
made it obvious to us that our media will not be accepted unless they are confident that we have worked
closely with your office to insure proper characterization. They must feel confident that they will be able
to dispose of the media when it is spent

        Our media is not specifically listed under 40 CFR as hazardous, and it does not exhibit any
characteristics of hazardous materials as defined under 40 CFR 261 Subpart C. During our November
17th meeting,, members of your staff were particularly concerned  with the possibility of free cyanide gas
liberating from the media under various pH conditions. It was agreed that an outside source would test for
cyanide  liberation under conditions defined in EPA method 9010 (Revision 2, Sept  1994).  I have
attached a copy of the report from the University of Helsinki verifying that no free cyanide gas is liberated
by our media. I have also attached copies of a toxitity report, 11/17/95 meeting notes and our written

-------
correspondences, to date, as evidence that we have thoroughly explored the question of hazardous
classification.

        Since our potential customers have expressed concerns about this product, we respectfully request
that your office verify our findings in the form of a letter.  We would like you to state that based on the
evidence presented and on the current regulations, this media would not be considered hazardous in either
its unused (potassium) or spent (cesium) forms.

        Thank you in advance for considering this request and a special thanks to your staff members

  Dear Mr. Jones,

         Thank you for your letter of June 19, 1996 on EPA's revised "Policy on Enforcement of
  RCRA Section 3 0040) Storage Prohibition at Facilities Generating Mixed Radioactive/Hazardous
  Waste." In that letter you express concern that the policy defines "commercially available
  treatment technology and disposal capacity" to include a facility that has a RCRA permit, interim
  status, a Research, Development, and Demonstration permit, or a Land Treatment permit. You
  indicated that based on this definition a generator might assume that recycling facilities are not
  included as acceptable alternatives for mixed waste disposal. I would point out that the policy
  does suggest several available alternatives (without specifically endorsing any one of the
  alternatives) which a generator might explore to dispose of material that is both hazardous and
  radioactive.  Molten Metal's trademarked Quantum-Catalytic Extraction Process is mentioned in
  the policy as a recent technological development.

         There was no intent in the definition to exclude legitimate recycling facilities, but rather to
  emphasize the use of permitted facilities for waste treatment and disposal.  Of course, if the
  material is legitimately used as an ingredient in a manufacturing process, or if a legitimate
  recycling facility that meets, or is exempt from, RCRA requirements is available to accept
  materials EPA would not extend the enforcement policy to generators that did not avail
  themselves of legitimate recycling opportunities. EPA seeks to encourage the reuse of materials
  when this is possible. I trust this clarifies this issue. If you have further questions, you may wish
  to contact Nancy Hunt at 703-308-8762, since she chaired the EPA workgroup that drafted the
  revised enforcement policy.
                                       Sincerely yours,

 Dear Mr.. Weiner:

        Thank you for your letter of March 12, 1996'regarding the regulatory status under the
 Resource Conservation and Recovery Act (RCRA) of spent copper etchants managed by Heritage
 Environmental Services, Inc. ("Heritage").  You raised an important question, and we appreciate
 your interest in this matter. I hope the following discussion addresses your concerns.

        As we understand it, Heritage receives spent etchants from the manufacturers of printed
 wire boards. At its facility in Indiana, Heritage then uses the etchants to produce trirbasic copper
 chloride (TBCC), an animal micronutrient.  A residue generated in the TBCC manufacuring
 process is then treated .by adding additional chemicals to produce "fresh" alkaline etchaht.
 Heritage argues that they are using the spent" etchant as an ingredient in an industrial process to
 make a product (i.e, TBCC).> This kind of use would exclude the etchant from the definition of
 solid waste as long as no reclamation occurred (see 40 CFR 261.2(e)(l)(i), adopted verbatim by
 the State of Indiana at 329IAC 3.1)). The Indiana Department of Environmental Management
 (IDEM) has determined that the spent etchant. at Heritage's facility is indeed being used as an
 ingredient in an industrial process, and that this use meets the terms of the regulatory exclusion.

       As stated in  your letter, you believe that Indiana was incorrect in its interpretation, and
you asked the Environmental Protection Agency (EPA) to request that the state revise its
determination.. Your belief is based upon the Agency's preamble discussion of this regulation at
50 FR 614, 619 (codified at 40 CFR 261.1 (c)(5)(i)).  In that discussion, EPA stated that "when
distinct components of the material are recovered as separate end products (i.e., recovering lead
from scrap metal in smelting operations), the secondary material is not being used, but rather
reclaimed and thus, would not be excluded under this provision". Since Heritage is producing
separate products at its plant (i.e.,. TBCC and "new"etchant), you have argued that  reclamation is
occurring which would disqualify the entire process from exclusion under 40 CFR 261.2(e)(l)(i).

       At issue in this case are two operations. In the first operation,  a spent material is used as
an ingredient to make a product (TBCC), resulting in a residue. The second operation uses the
            Rocycled/Rocyclabja • Primed whh Vegetable Oil Based Inks on 100% Recycled Paper (40% Postconsumer)

-------
  residue from the first to make another product (fresh etchant), but the second operation may
  involve reclamation (although the IDEM has not made a formal determination on this point).  If
  we assume reclamation occurs in the second operation, the question is whether a facility would be
  barred from claiming the use-as-ingredient exclusion because of the subsequent reclamation.  The
  answer to this question depends on whether the operations are considered to be one industrial
  "process" (in which case the reclamation would presumably disqualify the facility from claiming
  the exclusion) or two sequential "processes" (in which case the reclamation in a subsequent
  process would not generally nullify the exclusion).

        RCRA regulations, preambles, and past interpretations do not define how many (or how
 few) operations may be included in an industrial process. In EP A's experience, situations at
 different facilities vary so much that it is not possible to develop a general rule about whether
 operations should be considered one process or multiple processes.  The Agency believes that
 any such rule would inevitably be too inflexible to address the many different types of industrial
 operations being conducted throughout the country,  for this reason, we have historically left the
 determination of this question to States authorized to administer and enforce the RCRA program
 under section 3006, or to EPA Regions where the State is is not authorized, ^uniform national
 interpretation would not be adequate to address the large variety of circumstances prevailing at
 different industrial facilities.. States and Regions are more competent to evaluate the site-specific
 factors that must necessarily enter into this kind of decision.

       We have consulted with Region V after their meeting on June 25, 1996 with
 representatives from Phibrotech, the Illinois Environmental Protection Agency, and the IDEM.
 The Region and the States would like to thank Messrs. JackBenheim and Tom'Moran for taking
 the time to further discuss these issues with them. As you are aware, most of the issues discussed
 during the meeting had been evaluated before, but the discussions served to underscore the
 complexity of these regulatory determinations, particularly with respect to the Heritage operation.
 Follow-up discussions between Region V and the IDEM indicate that the IDEM remains
 committed, to its original ruling on the Heritage process.

       Based on our discussions with Region V and the State of Indiana, and a review of existing
 policy, we believe that Indiana's interpretation of 40 CFR261.2(e)(l)(i) is not inconsistent with
 the language of this provision. For this reason, we will not request the State to revise its
 determination.

       As you may be aware, EPA is currently engaged in an effort to change the RCRA
 regulations governing hazardous waste recycling.  This effort has three goals. First, we want to
clarify and simplify these regulations to make them more "user-friendly" for all concerned, while
still folly protecting human health and the environment.  We also want to remove disincentives
that may lead industries to dispose of their wastes rather than reusing them. As part of this
effort, we plan to reexamine and possibly change the current regulatory distinctions between
"reuse" and "reclamation". The Agency hopes to propose these regulatory revisions in early
 1997.

Mr. Jack L. Cooper, Director
Environmental Affairs
National Food Processors Association
1133 20th St. N.W.
Washington, D.C. 20036

Dear Mr. Cooper:

     I am writing in response to your letter to me of July 30,
1980 and your visit to the Agency on July 25, 1980.  You raised
several issues in these communications which relate to the impact
of the hazardous waste regulations  (as promulgated in the Federal
Register on May 19, 1980) on food processors.

     Specifically, the food processors frequently use a dry-
caustic peeling process which produces a waste which may, on
occasion, exhibit the hazardous waste characteristic of
corrosivity since its pH would equal or exceed 12.5.  You further
indicated that this waste is always neutralized to well below a
pH of 12.5 and thus would not be a hazardous waste when it leaves
the plant for final disposition.  You also indicated that you
feel such wastes, and the facilities generating and treating such
wastes, should not be included in the RCRA Subtitle C program.

     In re-evaluating the regulations and our intent to only
control those hazardous wastes which if improperly managed may
present a potential hazard to human health and the environment,
it appears that some modification to the regulations may be
warranted.  The Agency disagrees, however, that the appropriate
approach is to declare caustic food processing waste non-
hazardous.  To do so would be inconsistent with EPA's May 19,
1980 regulations which identify highly corrosive wastes (pH above
12.5 or below 2.5) as hazardous wastes.  Such wastes can cause
serious burns or seriously pollute surface waters.  In the case
of your industry, overflows and leaks resulting from improper
operation could result in injuries to persons who might have
access to the area.  Improper management could also result in the
release of toxic lists and fumes.
        This has been retyped from the original document.

-------
                              - 2 -

     In sum, we don't think it appropriate to exempt a waste as
non-hazardous because it is usually adequately managed.  Such of
the Act.  The structure of RCRA involves a determination first
appropriate regulation, the Agency is directed to assure the
public that management is safe.  Unless regulations requiring,
proper handling are imposed, the Agency and the public have no
assurance that proper management is being achieved.

     To make this same point another way, an interpretation such
as the one you are requesting would allow a great majority of
waste producers to seek exclusion from the program on the grounds
that they manage their wastes properly.

     On the other hand, the Agency agrees that imposition of some
of the provisions of the May 18, 1980, regulations may be
unnecessary for relatively simple neutralization facilities.  A
more appropriate approach might be to establish a special set of
standards applicable to neutralizations to implement such an
approach.  We hope to make a decision on this regulations before
November 19, 1980, the effective date of the May 19, 1980,
regulations.

     I would like to thank you for bringing this particular
problem to our attention.  Our goal is to promulgate a set of
regulations which will protect human health and the environment
from the improper management of hazardous waste, but yet not
place an unnecessary burden on American industry.  Please feel
free to call Mr. Alfred Lindsey if you have any further
questions.  Mr. Lindsey can be reached at (202) 755-9185.

 Dear Mr. Boris:

      I an writing in response to yor letter of May 11, 1981
 requesting a ruling on whether the American Foundrymen's
 Society (AFS) Standard Test Procedure in which the container
 is handshaken twice daily by inverting it 15 times is an
 acceptable agitation procedure to employ when conducting the
 Extraction Procedure toxicity test [40 CFR 261.24].

      The AFS method is not acceptable since it doe? not
 meet the definition of acceptable agitation;   "...an
 acceptable extractor is one which will impart sufficient
•agitation to the  mixture to not only prevent stratification
 of the sample and extraction fluid but also insure that all
 sample surfaces are continuously brought into contact with
well mixed  extraction fluid".   Specifically the AFS method  is
 deficient  in that during the 12 hours or more that the sample
remains  undisturbed,  stratification is likely to take place.

      The magnetic stirrer method you  also asked about may
however  be used if,  after application of  the  Structural
Integrity Procedure,  the waste  material is a  monolithic
piece.   By suspending the sample in a continuously stirred
bath  of  extraction  fluid,  the objectives  described in the
aforementioned specification will be  met*

     I hope  that  this  answers you question.   If you have any
additional questions/ please feel free  to give  me a call at
(202) 755-9187.

MEMORANDUM

SUBJECT:  Ignitable Solids Definition

TOt       David A. Wagoner, Director
          Air and  waste Management Division, Region VII


     As you requested in your «iemo of December 15, I an writing
to clarify the definition of an ignitable solid under 40 CFR
261.21 as it applies to materials such as titanium swarf.

     As Gene Grumpier correctly advised Greg Weber- of Region V,
in order for a solid waste to be an ignitable waste it must
be capable, under  standard temperature and pressure, of both
causing fires through friction, absorption of moisture or
spontaneous chemical changes and burn so vigorously and per-
sistently that it  creates a hazard.  Thus, if the titanium
swarf is very difficult to ignite it would not be classified
as a hazardous waste even though, once ignited, it oay pose  a
hazard.

     In order to remove the ambiguities inherent in such a
definition, OSW is in the process of developing specific testing
methods and hazardous waste definition thresholds for ignitable
solids.  However*  such tests are not expected to be ready tor
proposal until PT  84.

     If you have any comments or questions concerning the
ignitable waste definition please give David Friedman or
Florence Richardson a call at PTS 382-4770.

                                        JANUARY 83
o  Question:      A wastewater which  is not  identified or listed in 40 CF3
                  Part 261 is placed  in a surface  impoundment for dewatering.
                  A constituent of the wastewater  is reactive when dry.
                  Does the surface impoundment becane subject to RCRA if it
                  never dries out..during its active life?

   Answer:        the surface impoundment becomes subject r.o RCRA when it dries
                  out after receiving its final volurte of waste,  if the waste
                  is immediately reooved as it becones reactive {dewatered),
                  then the operator would be a generator for that waste.    If
                  the waste dries out first and becomes reactive, then the surface
                  iropouncberit would be subject to the regulations.

It is still testable if it contains  free liquids (water).   The

determine if there are free liquids.

Although most of tjhese samples were collected from mining  and bene-     ~
ficiating* wastes, two samples were collected  from gypsum waste—        ^
gypsum pond liquid and^gypsum pond embankment.  Analytical results      £
indicate that sjetals concentrations in the gypsum pond  liquid           \
exceeded EF «Miclty values for eadmlum and chromium.   Acetic  acid      f
extract from «Ji« gypsum pond embankment did not fail any of the EP      £

contained 1.4 pioocuries/gram of Radium 226.                            2

     On Decesiber 18, 1978, EPA proposed hasardous waste regulations
.containing guidelines in the form of an advanced  notice of proposed
rulemaking concerning Radium 226.  According  to the  advanced notice
of proposed regulations, a waste would be  considered hazardous when
the total analysis for Radium 226 was equal to or greater  than a
concentration of 5 picocuries/gram for solids.  To date EPA has not

tear Mr. wilders

     I a* writing in response to your July 14, If83 request for
clarification of the Resource Conservation and Recovery Act (RCRM
hazardous waste identification regulations as they apply to waste
batteries and cells.

     A* we discussed in our telephone conversation on July 1, 1983,
most common batteries and cells rapidly degrade when placed in a
landfill.  Thus, when testing such products to determine if they
exhibit the Extraction Procedure Toxicity characteristic (40 CFR
261.24) the batteries and cells should be cut up into email pieces
(i.e., to pass 1 cm sieve).  If, after such preparation, none of
the concentrations listed in 40 CFR 261.24 Table 1 are exceeded
the batteries are not hasardous wastes and may be disposed of in
a sanitary landfill.  Batteries that yield extracts exceeding one
or more thresholds are hazardous wastes and Bust be disposed of
in a RCRA permitted facility.

     Certain batteries and cells, however, are manufactured in
such a manner as to prevent disintegration after disposalo  Such
products way be tested without being cut up.  At this tine,
we have not developed, testing thresholds for identifying such abuse
resistant products*  Pending development of such tests you may
evaluate the corrosion resistance of your products using a salt
water solution*  If after subversion for 1 month in a salt water
solution no leakage occurs, the product can be considered to
be corrosion resistant*  It the package is also structurally
resistant to crushingr it can be evaluated in the IP Toxicity
test without being out op.

     X trust that this explanation assists you in evaluating your
wastes.  I would like to also bring to your attention the fact

-------
that we have a toll free hotline  (1-800-424-9346), iff you ever
need assistance with any aspect of the RCRA regulations.

State Program Section (8AW-WM)

     We have reviewed your submissions related to the Chemical
Agents Munitions Disposal System facility.  Our preliminary
assessment of the properties of agents GB (isoproplyl methyl
phosphonofluoridate) VX (Ethyl-S-diisopropyl aminoethyl methyl
phosphonothidoate), and HD (Bis-2-chloroethyl sulfide) lead us to
conclude that the wastes should be considered hazardous due to
their reactive nature.  While the wastes are not specifically
listed at this time, we believe them to be reactive according to
the definition of §261.23 (a) (4)  — namely,  when mixed with
water, they generate toxic gases, vapors, or fumes in a quantity
sufficient to present a danger to human health or the
environment.  The gases of concern in each case are as follows:
for GB, emissions of hydrogen fluoride which has a TLV of 3 ppm
in air; for HD,  emissions of hydrogen chloride which has a TLV of
5 ppm; and for VX,  emissions of diethyl methyl phosphonate, bis-
ethyl methyl phosphonic acid and bis-S-(diisopropyl amino ethyl)
methyl phosphonodithiolate.   In the case of VX, the emitted gases
are indicated as toxic decomposition products that would be
emitted upon addition of VX to water.  (The reference for these
anticipated emissions is the Army's field manual on military
chemistry.)  Sufficient quantities of any of these chemical
agents, when mixed with water,  would be expected to emit gases at
levels of concern and, thus,  exhibit the characteristic of
reactivity.  In addition, mustard gas could meet the criteria in
§261.23(a)(5), due to emissions of sulfides.

     With respect to our ultimate plans vis-a-vis these wastes,
we do expect to develop listings for all three agents.  These
listings would probably be developed under the criteria of
§261.11(a)(2) and result in the designation of the wastes as
Acute Hazardous Waste.  Unfortunately, other priorities and a
general dearth of available information will hinder our efforts
and may result in the passage of considerable time before these
listings are finalized.  We are not overly concerned about this
delay, however,  since the State's letter suggests that these
wastes are being managed in a manner consistent with their
extreme toxicity.  In addition, as we have stated above, the
wastes are currently regulated.  Nevertheless, it would be useful
to our efforts if your group or the State agency could submit
information on the wastes and the corresponding treatment and
disposal options under discussion.

           5. a. How does one perform the EP toxicity test on oily wastes?
              The waste in question does not pass through the filter and is
              inroiscible in water.

              b. Is there another extraction procedure test for such wastes?

                  a. The EP toxicity test is conducted using the filtrate
                  from filtering a sanple.  Solid or oily material that do not
                  pass through the filter are subject to the EP extraction and
                  the resulting extract analyzed to determine if ths waste is
                  b. There is a variation of  the EP toxicity test specifically
                  for oily wastes which is used in the de list ing program.  It
                  is not regulatory, however, under 261.24.  A copy of this
                  procedure may be obtained for use in experiments froa Tbdd

     This is in response to your recent memorandum requesting
clarification of the definition of a reactive waste as it applies
to out-dated blasting caps.  According to 40 CFR 261.23, a wasta
which is capable of detonation or explosive reaction, if subjected
to neat or a strong initiating force, is a reactive hazardous
waste.  Blasting caps clearly fall within that definition.

     As you brought to our attention. Section 2.1.3 of "Test
Methods for Evaluating Solid Waste* (SW-846) appears, however,
to suggest otherwise.  A note in the manual states that blasting
caps in quantities of less than 1000 are not a hazardous waste.
This is a mistake.  SW-846 is a compilation of sampling and
analytical methods that may be used to test for the presence of
Appendix VII or VIII constituents.  It is not, however, the
basis on which the identification or* listing of a particular
material as a hazardous waste is made.  Thus, Note 5 in Section
2.1.3 of SW-846, should be disregarded.

    A package of revisions and updates to SW-846 is currently in
preparation; as part of this update, Note 5 will be deleted to
prevent future misunderstanaings,  we appreciate your bringing
this problea to our attention,  if you have any questions, please

An aqueous waste containing small amounts of an organic
compound flashes in a Pensky-Martens Closed Cup Tester.
Is this waste RCRA ignitable or is it excluded- from that
definition because it "contains less than 24Valcohol?"
The waste has no alcohol in 1t.

    If an aqueous waste contains no alcohol, it is not excluded
    from the definition of ignitable as 1$ wine or latex paint.
    Hence,  if the flashpoint is less than 140*r, the aqueous
    waste 1s deemed ignitable,  EPA is working on developing
    a test  for such wastes to determine if they would sustain
    coRDustion or only flash in the Closed Cup Tester.

     This letter responds to your inquiry of November 9, 1934,         <~
regarding the correct designation for waste ink and solvent            £
mixtures generated from printing facilities.                            l

     First, waste inks containing solvents are not listed hazardous
waste; however, these inks are considered hazardous wastes if they
exhibit one or niore of the characteristics of hazardous waste
(i.e., ignitability, reactivity, EP toxicity and corrosivity).
In your particular case, waste ink containing HER, MIBK, toluene,
xylene, and acetone will probably exhibit ignitability.  Should
this be the case, these wastes arc doomed hazardous waste and,
as such, should be designated as EPA Hazardous Waste Number 0001.

     Solvent mixtures frota the cleaning of pumps, lines and
tanks, as described in your letter, are not currently covered by
the solvent listings in 40 CPR 261.31.  Therefore, they are
hazardous waste only if they also exhibit one or more of the
characteristics of hazardous waste,  within the next few months,
the Agency will propose to amend the listing to include certain
solvent mixtures.  Thus, many of these solvents will be brought
under Subtitle C control.

     If your waste management activities occur in a state that
has been authorized under RCRA, then the state rules, rather than
the Federal rules, apply.

     Me recommend that you consult with the appropriate states
to determine whetheY they interpret their listing as covering
solvent mixtures.  Agency data indicate that New York Stato

-------
interprets their listing as applying.to solvent mixtures as well
as single solvents.  In addition, it is within the authorized
State's discretion to determine the appropriate classification
for wastes that are both listed and exhibit a characteristic.

     Should you have questions, or require additional information,
please contact Jacqueline Sales, of ray staff, at (202)  3R2-4807."

Mr. W. a. Yancey
P.O. Box 1675
Houston, TX 77251

Dear Mr. Yancey:

     I an glad to clarify the issues of hazardous waste
identification you raised in your letter dated November IS, 1934.

     First, you .asked if physically solid forms of sodium hydroxide
and potassium hydroxide (granular or pellets) are currently
regulated as RCRA corrosive hazardous waste.  The answer is no.
Title 40 CFR $261.22(a) defines corrosivity for aqueous solutions
within given pH ranges and for liquids that corrode steel faster
than a quarter of an inch per year under specified test conditions.
The May 19, 1980, preamble, 45 PR 33109 states:

       "...there is no demonstrated need to address corrosive
       solids at this tine.  EPA will, however, continue to
       seek, information on the dangers presented by these wastes
       and will consider specific regulatory measures if the
       need for more control becomes apparent."

At this time, the Agency is developing a test protocol to
evaluate the leachability of solid-phase corrosives.  Further-
more, the new RCRA amendments direct EPA to minimize effects
of hazardous waste on human health and the environment.  So
you can see that the status of corrosive solids may be subject
to change in the future.

     Second, you wondered if products that contain preservatives
*OB. listed in 40 CFR S261.33(£) are subject to regulation as
RCRA hazardous waste,  in particular, you asked abou£_pia£A£o__
search that haa been treated wi^h f~—«-'|4?hy'1'». JTh<> conunent
after 40 CFR §261.33(d) explains that commercial chemical products
are manufactured For commercial use and are commercially pure or
technical grades or formulations in which the chemical is the
sole active ingredient.  The comment also says that a waste that
contains a chemical listed in $C261.33(e) or  (f)  is only a RCRA
waste if the waste is listed in $5261.31 or 261.32 or  if the

-------
waste   does not  specify
the  amount  of cyanides or sulfides that  would identify  a waste
as  reactive.  Presently, EPA is in the process of developing
test protocols to quantify the reactive  characteristic  for
cyanides  and sulfi'des.  in the meantime, the enclosed regulatory
interpretive letter, RIL #2, outlines  the  Agency*a suggested
guidelines,  fee low  10  ppm, the waste will  not be considered
reactive, and above 200  ppn, it will be  considered reactive
unless the  generator can show  why it is  not.  Between 10  and 200
ppm, the  decision will be based on the potential releasibility
of  f*2S or HCN on  a  case-by-case basis.

     All  but about  seven states and three  territories have programs
that operate in lieu of  the Federal RCRA program, 'and eight of
these  programs have received full "authorisation.'  When  a  State
has  been  granted  authority to  operate.the  RCRA program, you are
subject  to  the State regulations which nay be slightly  different.
The  RCRA/Superfund  Hotline at  (800)424-9346 can send you  a'copy
of  the State hazardous waste agency addresses and phone'numbers
if you need it.

     If  you wish  to discuss those questions further, please do
not  hesitate to call me  at (202)382-4804.

                                Sincerely  yours,

     Recently, a question arose as to the status under ^C^A of          -
off-specification small arms ammunition (ball or sporting               ^
ammunition of calibers up to and including 0.50) intend**d for           V
disposal.  The issue concerned whether such wastes are "reactive        **
wastes" within the meaning of 40 CFR 2fil.23(a)(<>) and, thorefor<»,        i
subject to RCRA hazardous waste requirclients.  Because the              £
ammunition contains an ignition source that may be shock and heat       ^
sensitive and is designed to generate high pressure during use, it      .-
had been our opinion that it is probably "reactive."  However, on       £
the basis of information that was received from the Remington           ^
Arms Company and the Army, we now conclude that such materials'         s,
are not "reactive" within the neaning of 40 CFR 261.23 (a) (6V.          §

     Section 261.23 (a) (6) of Title 40 provides thit a solid            'o
waste which is "capable of detonation or explosive reaction if it       *
is subjected to a strong initiating source or if heated under           »
confinement* is "reactive.*  A3 discussed in the May 19, 1<»SO,
preamble to 40 CFR 261.23, shock and thermal instability are
important elements of this definition,  while presently there  is
no Agency guidance regarding these criteria, the Remington Arms
Company of Independence, Missouri, and the U.S. Army have provided
information which addresses both of these factors.
               Anas Company submitted- details on the effects of
heat and impact to small arms ammunition.  There was no  explosion
when a box of awmin^tion was set afire.  Small ar*»s, when  subjected
to the SAA'-II (Sporting Am.s ah-1 Ammunition Manufacturer's  Institute)
Impact Test, shoved no evidence of mass propagation or explosion.

     The Department of the Array has a rigorous safety and hazard
testing program on .all munition items.  The tests/ which include,
drop tests from 5, 7, and 40  feet to simulate handling errors
and ."heating under confinement," 160*F for 4% hours, also
showed no evidence of detonation or explosion with respect to
small arras ammunition.   The  tests were performed on both the
individual munition and  a package containing a prescribed number
of items.

     As noted above, we  fe«l  that results from these tests show
that off-specification small  caliber ammunition up to and including
0.50 Is not "reactive" within the meaning of 40 CFR «2*1.23 («H*T
He, therefore, believe that the disposal of such ammunition is not
subject to Subtitle C hazardous wants requirements.

Dear Mr. Morris:

     This is in response to your letter of January 7, 1985,
which questions the proper management of excavated construction
•oil that contains detectable quantities of volatile organic
compounds.  RCRA regulates the characteristic wastes discussed
in 40 CFR Sub part C and listed wastes designated in 40 CPR
Subpart D.

     To qualify as a characteristic waste, the soil rould have
to be ignitable { S261.21 ( a) (2) ) , or contain a liquid phase
that is corrosive ($261.22), or exhibit any of the reactivity
criteria ($261.23), or be  above the EP toxic levels (§361.24)*

     In order to be a listed waste, the soil would have to
contain known listed waste that ares

     1) commercially unused S261.33(e) or (f) chemical* or
        off-specification species, formulations containing
        them as sole active ingredients, and container
        residues or spilled material of the above i

     2) specific industrial waste streams specified in
        $261.32; or

     3) non-specific waste streams listed in $261.31.

As you stated, in many cases, the exact source of th«* volatile
orrjanics cannot be determined.
     Under the Comprehensive Environmental Re«non««,
and Liability Act, hazardous substances are currently only
those specified under th<* Clean Water Act, the Clean Air Act,
the Toxic Substances Control Act, and HCRA listed  and character
istic waste.  Therefore, disnosal of aoil contaminated  with
hazardous substances must follow CEPCLA guidance also.

-------
     You should be in touch with the State* because they »ay
regulate soils that contain volatile organic compounds in a
different manner.  Please feel free to contact *e or Alan Gorson
of By staff again if you hare any other questions*

                              Cordially yours,

Dear Mr. Waltevi

     I aa writing in response to your recent letter requesting            [
clarification of the definition of the characteristic of iqnit-
ability for hazardous waste*.

     Your understanding that the word* "it is a liquid, other
than an aqueous solution containing less than 24 percent alcohol
by volune" were intended to exclude alcoholic beverages, such »<*
wine, and non-liquid materials is correct.  However, while the
Agency's intent was that this exemption apply to potable beverages
only, because the term "alcohol" was used instead of "ethanol,3
all aqueous wastes which are iqni table only because they contain
alcohols (here using tne tern alcohol to mean any chemical containing
the hydroxyl l-OHj functional group) are excluded from
     While the Agency completes the process of officially adoptina
a method for identifying "free liquids," for use in the 'land
disposal regulations, it is our current practice to employ method
9095 (see "Test Methods for Evaluating Solid Waste, SW-'US") for
such purposes*  Any material passing through the paint filter is
deemed to be a liquid.

     With respect to what constitutes an "aqueous solution."
such a solution is one in which water is the prirmry component.
This means that water constitutes at least ^0 percent hy
weight of the sample.  Although, we have not officially approved
any test methods for determining a waste's water content, *nv
competent laboratory should be able to make such a determination
using standard techniques (e.g., Karl Pisher titration, GO.

     We share your concern over the ambiguities in the current
ignitability definition and have a prog ran underway to correct
the characteristic's shortcomings.  Specifically, changes are
under development to replace the alcoholic solution exclusion

-------
                              - 2 -
with a generic exclusion for those wastes which, while possessing
a flash point below 60*C, neither continue to burn nor, if they
do burn, release enough energy to cause a major fire.  In addition,
steps are being taken to expand the ignitability characteristic
to include wastes which are physical solids.  Both of these
changes will involve proposal arrl promulgation of specific
definitional test methods and thresholds.

     I hope this information clears up any questions you way
have about the ignitability characteristic.  If you have any
further questions concerning any of the hazardous waste
characteristics, please contact David Friedman, of *ty staff, at
202-382-4770.

Manager, Environmental Conservation

P.O. Box 2197
Houston, Texas  77252

Dear Mr. Thoem:

     I am writing to clarify several aspects of the sulfide
reactivity characteristic that you asked about in your letter of
June 24, 1985.

     At present, there is no approved test method for determining
whether a waste exhibits the characteristic of reactivity.  I
have enclosed a draft of a test method for determining Total
Available Sulfide.  Work currently being done on the agitation
and waste introduction steps may result in significant changes in
the subsequent proposed test.  However, pending the conclusion of
our investigations, we recommend, and will accept, use of this
draft procedure.  While threshold concentrations have not yet
been promulgated by the Agency, we have adopted 500 mg/kg Total
Available Sulfide as an interim action level.  We consider any
waste that yields sulfide values at or above the action level,
using the draft procedure, to be hazardous.

     The 500 mg/Kg action threshold was arrived at by considering
a scenario in which a truckload of waste is discharged into a pit
containing (non-hazardous) acidic waste.  As a result of the
reaction of the waste with the acid, a rapid, high level release
of toxic gas ensues.  The objective of the characteristic is to
identify those wastes which, if such an activity were to take
place, pose a hazard to those persons in the general vicinity of
the disposal site.  While we have considered dispersion in
arriving at the action threshold, the specific dispersion model
that will be used in the upcoming proposal is still under
development.

     Ground water monitoring of all wastewater treatment lagoons
containing hazardous wastes, is required including those
containing only reactive wastes.  The only exemption from ground
water monitoring that is defined by the RCRA regulations is in
the case of neutralization ponds receiving wastes hazardous only
by reason of corrosivity (§265.90(e)).

     This monitoring is necessary because the Agency is not aware
of any mechanism which can assure that such wastes will not also
have toxic chemicals which pose a hazard to ground water.   The
        This has been retyped from the original document,

-------
fact that a waste is not listed or does not exhibit the
characteristic of Extraction Procedure Toxicity does not insure
the absence of leachable toxic species in the waste.

     If you have further questions concerning the reactivity
characteristic please contact David Friedman (202/382-4770) of
the Methods Program.  For information on the regulatory
requirements pertaining to ground water monitoring, contact
Robert April (202/475-8860) in the Ground Water Program.

Regulation Interpretation for Pesticide
Applicator Washing Rinsts Water

John fl. Skinner, Director
Office of Solid Waste  (WH-562A)

William Hathaway, Acting Director
Air and Waste Management Division   (6AW)
Region VI
             This  is  in response to the memorandum from Allyn Davis
        dated April 22, 1985,  regarding the regulatory status of
        washwaters that are generated by washing the exterior of a
        pesticide  aerial applicator's airplane.   As we stated in a
        previous memorandum to Region VII (dated June 16,  1982),
        the airplane  washing rinsewater is a hasardous waste via
        the mixture rule (S261.3(c))  if the pesticide residue on
        the aircraft  is listed in 40  CFR 261.33(e)  or (f)  (see
        attachment).   This  regulatory interpretation has created
        some concern,  especially regarding the  excessive impacts
        the hazardous  waste rules will have on  pesticide applicators
        and regulatory agencies.  Consequently,  we have been asked
        to reconsider our position  on this issue.

             Upon  reconsideration,  we now believe that we  have
        misinterpreted the  rules and  that the airplane washing
        rinsewater is  not hazardous via the mixture rule.   In
        particular, the mixture rule  states that when a hazardous
        waste is mixed with a  non-hazardous waste,  the entire
        mixture is hasardous,  unless  the waste  does not exhibit any
        of the hazardous waste characteristics  (i.e.,  ignitability,
        corrosivity,  reactivity,  and  extraction  procedure  (EP)
        toxicity)  or,  in the case of  a listed waste,  the mixed
        waste is delisted pursuant  to 40 CFR 260.20 and 260.22.  In
        the case of the airplane  washing rinsewater,  the mixture
        would have to be one of water and commercial  chemical
        product—namely, the pesticide.   The Agency does not believe
        that the pesticide  residue  left on the  aircraft is a discarded
        commercial chemical product.   The residue does not qualify
        as material discarded  or intended to be  discarded,  see
        Generally  45  Federal Register 33115, May 19,  1980.  in

listing commercial chemical products, EPA intended to
cover those products which, for various reasons, are thrown
away.  Id,  The Agency did not intend to cover those cases,
as here, when the chemical is released into the environment
as a result of use.  Unless we take such a position, one
could argue that the pesticide that is sprayed that does
not fall directly on the crop (but falls on the ground next
to the crop) would be disposal of an unused commercial
chemical product; such an interpretation is a distortion of
the commercial chemical product rule.

   Consequently, w« are withdrawing our previous interpretation
that airplane washing rinsawater is a hazardous waste via the
mixture rule.I/  Rather, this rinsewater would be defined as
hazardous only if it exhibits one or laore of the characteristics
identified in Subpart C of Part 261.

Mr. John Polich, P.E.
Gabriel and Associates
1814 North Marshfield
Chicago, Illinois  60622

Dear Mr. Polich:

     I am responding to your letter of July 18, 1985 requesting
clarification of the RCRA permit requirements that apply to a
specific wastewater stream, which is a mixture of methanol and
water, and which possesses the following characteristics:

                    Volume (30,000-50,000 gpd)
                    5-day BOD  (25,000 mg/L)
                    Suspended solids (300 mg/L)
                    Methanol (20,000 mg/L)

     This wastewater stream is a listed RCRA hazardous waste (EPA
No. F003) under 40 CFR §261.21.  Since the waste is listed for
the characteristic of ignitability and because it is a mixture of
a solid and hazardous waste (§261.3(a)(2)(iii)), it can only be
exempted from all RCRA requirements if you can demonstrate that
the waste is not ignitable.  To make this demonstration, you must
follow the procedures in §261.21 using a representative sample of
the wastewater stream.  If your waste is not ignitable, as a
result of analysis according to these test methods, you should
notify Mr. Horst Witschonke, Chief of the Illinois RCRA Unit, U.S
EPA Region V at (312) 886-0987.  He will evaluate the test data
and consider exempting the waste from RCRA regulations.

     Another option is to seek approval from the local POTW,
which has an NPDES permit, and which meets all the other
requirements of 40 CFR §270.60(c) for a RCRA permit-by-rule, to
accept your hazardous waste.  The POTW could allow you to pipe
the wastewater stream directly into a sewer, pipe, or other
similar conveyance at the point of generation, or to discharge
the waste at the POTW.  In the latter case, the hazardous waste
must continue to be manifested and transported according to the
RCRA requirements of 40 CFR Part 262.

     Finally, you should be aware of a new RCRA requirement
(Section 3005(h)) mandated by the Hazardous and Solid Waste
Amendments of 1984 requiring the owner or operator of an on-site
        This has been retyped from the original document.

-------
RCRA facility to certify that he has a program in place to reduce
the volume or quantity and toxicity of hazardous waste generated.
(See 50 FR 28733-34, July 15, 1985.)  To comply with this
requirement, I recommend that you consider reclaiming or
recycling the spent methanol in the wastewater (see 50 FR 616-
668, January 4, 1985 for the definition of hazardous waste
recycling activities).

     If you have any additional questions on these permitting
issues, please call Nancy Pomerlean at (202) 382-4500.

EP Toxicity for Oily Wastes

1.  With regard to the EP toxicity test specified  in 5261.24, there was a :nethcd
    1330 for oily wastes proposed to be added  to SW-846, "Test Methods for Evalua-
    ting Solid Wastes," which appeared  in  the  October 1, 1984 Federal Register
    (49 FR 38804).  At what oil concentration  should one use this modified E? ~toxi-
    city test for oily wastes?

      Method 1330 "Oily Waste Extraction Procedure' was developed for wastes
      containing oil or grease in concentrations of II or greater.  This method
      has seen used by EPA for generators  petitioning EPA to exclude their oily
      hazardous wastes fron the hazardous  waste listings (i.e., "delisting").

      Currently/ when determining if a  non-listed waste is hazardous with respect
      to EP toxicity, a generator must  follow  the procedure specified in 40 CFR 261
      Appendix II, not method 1330.   Method  1330 should be used only when requested
      by EPA for the purpose of delisting  a  hazardous wast*.

Dear Mr. Robbins:

     Thank you for your recent letter and suggestions on approaches
to the difficult problem of regulating the management of those
mining wastes which pose a hazard if improperly managed.  He share
your concerns both with respect to the suitability of using the
Toxicity Characteristic Leaching Procedure (TCLP) to identify
which mining wastes warrant RCRA regulatory control and the need
for tailored management standards for hazardous mining wastes*

    The TCLP was developed primarily to simulate the leachability
of an industrial waste co-disposed with sanitary refuse or other
putrescible materials*  Mining wastes, because of the relatively
large volumes of material involved, are not likely to encounter
such disposal conditions even if not regulated.  However, although
mining wastes are generally not acidic, many mining wastes contain
pyritic minerals which generate an acidic leachate upon exposure
to air.  Thus, the acidic environment modeled by the EP/TCLP may
be appropriate for mining wastes even if the model environment
used to develop the TCLP is not.  In fact, the leachate generated
by raining wastes can often be more acidic than the refuse derived
leachate.  Thus, a different leach procedure (which, for some
mining wastes, could be more aggressive than the TCLP) might be
appropriate.

     No decision has yet been made as to what type of test
procedure to use in identifying which mining wastes require
regulation under Subtitle C of RCRA.  A decision tree process  is
one approach that is being considered.  Any such decision tree
will require a method for determining the waste's acid generation
potential.  While we do not presently have any work ongoing to
develop test methods for determining a waste's acid generating
potential, we welcome your thoughts on this problem.  We would
also be willing to work with you and other interested parties  in
a cooperative effort to develop such a test.

-------
     As to your rec'iest for tailored management standards, we
agree wfth the need to develop tailored oanaqenent standards
for raining wastes before subjecting the* to Subtitle C control
and will indicate same in the 1986 Report to Congress*

     I appreciate ASARCO's offer of assistance in developing
protocols to assess the leaching potential of mining wastes.
I would suggest that you contact Alan Corson or David Friedman
(202/382-4770) to follow up on developing a cooperative
program in this area.

                               Sincerely yours,

Mr. Robert B. Carroll

Dear Mr. Carroll:

     I am writing in response to your petition requesting a change
in the extraction medium employed in the Extraction Procedure (EP)
from mild acetic acid to the tetra sodium salt of diethylene triamine
pentaacetic acid (DTPA).  We apologize for the delay in responding
to your petition, but your original letter was lost.

     The EP is designed to model waste leachability under a
specified mismanagement scenario.  This scenario assumes disposal
of the waste with municipal refuse.  The Resource Conservation
and Recovery Act charges EPA with identifying, as hazardous,
those wastes which may pose a danger to human health if mismanaged.
The codisposal scenario was chosen because we believe that it
accurately represents a reasonably aggressive mismanagement
scenario (i.e., it is unlikely that wastes which are not regulated
as hazardous will be exposed to leaching conditions more aggressive
than those modelled by this scenario).  While the EP is an accurate
simulation of this disposal environment, it is possible that oil
shale management constitutes a more aggressive leaching situation
than the codisposal scenario.  How poorly the EP procedure simulates
the leachability of the oil shale waste under commonly occurring
oil shale mismanagement appears to be the question?

     In your petition you cite the study by Esmaili, et.al.,
to show that the EP "does not work for retorted oil shale waste."
While DTPA may, admittedly, be a more aggressive extraction
medium than the mild acetic acid employed in the EP, we are not
aware of any data which indicates that DTP A more closely simulate
"real world" leachate generation than the EP does.  The fact
that DTPA is more aggressive does not, in and of itself, make it
more accurate.

-------
     Siaco the LP does not modal the specific environment dn-.
countered duriu^ tn* disposal of oil shale waste, it way fail to
iuentify such & disposal situation as hazardous.  The kC«A listing
process could be used, however, to bring such maaageraant under
regulatory control, if the waste c&n ba shown to present & significant
uctR^er to nur.vaa Uua.lt h or tne onvironaent.  aite and waste specific
leaching ^rocedures can be used in nafcing such a demonstration.
If you have specific data with which we can assess the accuracy
of this procedure or other candidate leaching procedures under
tno disposal c^^ditions encountered during oil shale management,
it mi^nt uelp speed up tha davelopoeat of such procedures.
Since, in th« c&*« of petitions, the bur don of proving the value
of a proposed test falls on the petitioners, unless we receive
additional data to support the need for the change you have
requested (e.g., a couparison between actual leachate from retorted
oil shalo waste disposal facilities and EP and DTP A leashing
data) we will not b* able to proceed any farther with the petitions.
You had also requested that we publish your petition in the
Feaeral Kejister.  It is our policy only to publish a notice of
receipt of petitions ani not the conplete petition.  He anticipate
publishing such a notice in the near future.  If you would like
to discuss tue specific information needed to proceed with this

   1.  Solvent Mixture Rule

       A product contains two active ingredients,  toluene and benzene.  This unused
       product is spilled on the ground.   How is the spill and spill residue regulated
       under RCRA?  Will the proposed solvent mixture rule in the  April 30, 1985
       Federal Register (50 PR 18378) affect this?

          Currently, if a product with more than one active  ingredient is  spilled, it
          will not be classified a* a •?• or *U" spill residue per 5261.33 since  the
          product contains more than one  active ingredient.   Th«? proposed  solvent
          mixture rule (50 PR 18378) does not change the  answae since the  proposed
          rule only addresses spent solvent mixtures.

          If the soil mixed with the spilled product meets a characteristic of hazar-
          dous MMt* in Part 261 Subpart  C, then the soil is & HCRA waste.  If the
          soil Mixture does not meet a characteristic of  hazardous waste,  RCRA is
          not applicable.  CEPCLA reporting may be required  if the reportable quantity
          is exceeded since benzene and toluene are hazardous substances.

Dear Mr. Corpuz:

     This is a follow up to our  conversation of  January  14,
concerning spent iron sponge.  A spent  iron  sponqe  material  which
evolves nore than 500 mq/kg i^S  is considered reactive by our
current reactivity ttethod.  The  Department of Transportation
(DOT) requires a ten day oeriod  of exposure  to the  atmosphere*
as a staoilization time prior  to shipment (40 CFR J73.174).  The
facility performing this stabilization  requires  a permit from
the EPA to operate (40 CFR 270.10),  and if they  can show that
the waste is nonreactive after treatment, then the  vasfre's dis-
posal can be requlated as a non-reactive material.

Dear Mr. Andrewst

     This is in response to your letter of December 27, 1985,
concerning the regulatory status of the copper plating solution
that you receive at your plant site.  As I understand your
situation, you obtain from a copper plating operation a copper
sulfate bath (which exhibits the characteristic of eorrosivity)
at your plant site and react it with a chelating agent to
produce a material that is registered with the North Carolina
Department of Agriculture as a commercial fertiliser.  This
•aterial no longer exhibits the eorrosivity characteristic.
This material is then sold to farmers for use as a fertiliser
or is sold to fertilixer companies for inclusion into fertiliser
for resale.

     under this scenario, the copper sulfate bath that you
receive at your plant site is a solid and hazardous waste and
is subject to the transportation and storage requirements
under the hazardous waste regulations.  The material that is
produced at your plant site (i.e., the commercial fertiliser),
however, is no longer subject to regulation under the harazrdoua
waste rules and may be managed as such.  The basis for this
decision is as followsi  On January 4, 1985, EPA promulgated
its final rules which deal with the question of which metarials
are solid and hazardous wastes when they are recycled.  Among
other things, these rules state that all hazardous secondary
materials that are placed on the land for benefical use or
incorporated into products (referred to as waste-derived
products) that are placed on the land for benefical use are
solid and hazardous wastes.  (See enclosed copy of regulations.)
in the Agency's view, these practicss are virually the equivalent
of unsuperrised land disposal, a,situation RCRA is designed
to prevent.  The many damage incidents resulting from wastes
being placmd on the land for benefical use bear out the
Agency's concern.  This type of recycling activity has also

-------
been a particular concern of Congress.  in particular, in a
number of Congressional reports, they describe various damage
incidents involving wastes that are placed on the land for
benefical use.  These reports reflect not only Congress*
concern but its intent that EPA regulate this type of activity.
Therefore, we believe that this type of recycliiig activity
constitues waste management and need be subject to regulatory
control.

     By asserting jurisdiction over waste-derived products
that are placed on the land, we are also asserting Jurisdication
(and regulating) the materials that go into these products,
provided these materials are hazardous (i.e., exhibit one or
more of the hazardous waste characteristics or are specifically
listed).  Therefore, since the copper plating solution is
corrosive, it is subject to regulation.  More specifically,
the generator and transporter of this material is subject to
the appropriate generator and transporter standards,  including
the hazardous waste manifest, while you (being the recycler)
would be subject to the appropriate storage standards.  (See
40 CPR 261.6(b) arid (c) for specific regulatory requirements.)
As indicated earlier, however/ the material that is produced
at your facility — the commerical fertiliser — is no longer
subject to regulation since this material is no longer defined
as hazardous.

     Since this regulation has gone through formal rulemafcing,
your only alternative (at this time) is to submit a rulemaklng
petition under 40 CFR Part 260.20 (See enclosure for  specific
information requirements).  Please feel free to give me a
call if I can be of any further assistance; my telephone

1.   spent Solvent Mixtures

    In the December 31, 1985, Federal Register (50 FR 53315), EPA attended the listing
    of hazardous wastes in §261.31 to include certain spent solvent mixtures.  In
    this final rule, spent solvent listings F001, F002, F004, and F005 were redefined
    to include mixtures containing ten percent or more total listed solvent (by
    volume).  However, the ten percent threshold for solvent mixtures was not applied
    to the F003 solvents listed solely for ignitability because the tejency determined
    that these solvents may not be ignitable at such low concentrations.   Additionally
    the Agency did not remove these ignitable spent solvents from the list of hazar-
    dous waste since the solvents have not been evaluated for their toxicity.  How
    then are mixtures of ignitable solvents regulated?

         If a spent, non-halogenated solvent has been listed only for showing the
         ignitability characteristic (i.e., listed as F003), then mixtures or olends
         of such solvents will remain listed as F003 wastes as long as the mixture
         or blend consists only of F003 listed solvents.  For example, a blend of
         80% ethyl acetate and 20% xylene would be classified as F003 while a blend
         of 80% ethyl acetate and 20% petroleum solvents would not be F003.  However,
         the ethyl acetate and petroleum solvent would probably exhibit the iynita-
         bility characteristic and be classified as D001.  Finally if a solvent blend
         consists of a solvent listed under F003 plus 10% or more of any solvent
         listed under F001, F002, F004, F005, then the resultant spent mixture will
         be listed as F003 and the other spent solvents (i.e., F001, F002, F004, or
         F005) respectively.

Dear Mr. Agidi

     in our telephone conversation of March 11, 1986, ve
discussed the detection limit for the BP leachate concentration
of selenium «0.2 ppm) cited in the del lit ing petition (1*20)
filed for the residual vast a/contaminated soil pit at the Boeing
Commercial Airplane Company - Fabrication Division facility in
Auburn, Washington.  I Indicated that, if the detection limit wee
used as a maximum BP leachate value in the TOS ground water »odel
analysis, the predicted cceipliance point concentration would
exceed the Agency's regulatory standard of o.Ol ppm.  Further
analysis is necessary in order to produce lover detection limits,
e.g. <0.1 ppm, that vould not produce a negative VH8 finding.
It should be possible, if the Maples are archived, to re-test
the existing samples using a method permitting finer detection
limits.  Other vise, additional representative samples must b«
tested to achieve lover detection limits for selenium.

     I have recently assumed responsibility for the review of

Dear Mr. Vaughnt

     I am writing in response to your request for a definitive
opinion on whether discarded fluorescent and mercury vapor lamps
would be classified as a hazardous waste under Section 261.24 of
the Resource Conservation and Recovery Act (RCRA) regulations.

     With only the data  you submitted, it is not possible for me
to give you a definitive answer to your question.  For example,
using the data presented on the GE HVR1000/VBU lann as a worst
case, the amount of mercury that is potentially available is
223 rag/kg of waste.  If  all the mercury was extracted into the
Extraction Procedure (EP) extract during the test, this would
yield an extract concentration of 11.3 mg/1.  However, mercury
is a relatively inert metal, with respect to reactivity toward
nonoxidizing acids such  as the acetic acid used as the extraction
medium in the EP.  In addition, while mercury has a relatively
high solubility in water (as compared to most metals), it solubility
is only  .02 mg/1 which is substantially below the regulatory
threshold of 0.2 mg/1.

     While I do not believe that either fluorescent or mercury
vapor lamps would b« hazardous waste under the RCRA regulations,
actual EP testing would  have to be conducted before any definite
conclusion could be drawn.  You should keep in mind, however, that
RCRA is  •> State administered program in those States that have
applied  for and received authorization.  In such States it is the
State program which must be adhered to.  Some States have more
stringent regulations than those of the Federal program.  Thus,
it is possible that a State may elect to regulate a waste as a
hazardous waste based on its total mercury content and not on
leachable mercury.  California may be one such State.  I recommend
you contact the California Department of Health Services for
State-specified regulations.

Dear Mr. Alfft

     This letter is to confirm our  conversations regarding
your intent to market equipment used to run the Toxicity
Characteristic Leaching Procedure  (TCLP).  As we discussed,
your designs for the rotary apparatus indicate that the device
meets the requirement for end-over-end agitation at approximately
30 rpm.  I will be adding your device to the list of suitable
rotary agitation equipment.

     You also presented designs for a zero-headspace extractor
(ZHE).  Unfortunately, it is not possible to make a decision
regarding suitability without data  comparing the performance of
your device to the other equipment.  To reduce potential
variability, it is necessary to insure that all devices are
capabable of producing similar results.

     As I suggested, you should consider evaluating your device
for comparability in two steps.  First, to insure that you are
in the right ballpark, you should  initiate experimental work to
determine recoveries of spiked volatiles from water (or from
TCLP extraction fluid) that has been run through the ZHE.  We
have done this work through one of  our contractors with the
other two ZHE devices* and comparable results would provide
evidence that your ZHE should be suitable.  Please call Dr.
David Taylor of S-Cubed at  (619) 587-8369 for information
regarding identity of the volatiles we used, the spike levels,
the spiking method, and the expected recoveries.  I have alerted
Dr. Taylor to expect your call.

-------
                               -2-


     Assuming that your recoveries are acceptable, testing of
actual wastes, and comparison to results obtained with the
other ZHE-devices, would be the next step.  Since you
understandably wish to avoid having to buy other devices in
order to make these comparisons, participation in our
collaborative study, also being managed by S-Cubed, would be
advisable.  Please contact Dr. Taylor if you wish to participate.

     Another alternative would be for you to initiate comparative
work through a laboratory that has already obtained these devices.
This alternative has several distinct advantages.  For one,
it would eliminate several variables that always exist in
collaborative studies, such as analytical variability.  A more
distinct advantage to you would be time.  You indicated that
you wished for your ZHE to be listed with the other ZHE devices
when the proposed TCLP becomes published in the third edition of
SW-846 (our solid waste testing manual), even if it was listed
with the caveat that it was still undergoing evaluation.  I
have talked this over with my management, and the decision was
made that the manual should only indicate that equipment which
has been shown to be acceptable.  For time reasons then, you may
wish to elect this other alternative.  Of course if you choose
this alternative you are still welcome to participate in our
collaborative effort.

     The time factor may be the deciding factor for you since
we will have to make a decision on equivalency by the end of
June to include your equipment in the 3rd edition of SW-846.
I recognize that this leaves you with less than two months
to initiate and complete the necessary comparative work.  If you
choose this route, however, I would be glad to provide you with
more assistance.

     I am sorry for having to present you with these hard choices.
You have obviously put a lot of effort into your development
work, and your design seems feasible.  I wish you had contacted
me much sooner with your intent.  We could have probably avoided
the time  factor.  Good luck and please call me at  (202)382-4795
if I can be of more help*

Dear Mr. Blackburn:

     This is in response to the  letters you have submitted
to the Agency in which you raise a  number of questions tor
our consideration.  First, let me apologize for tne time it
has taken to respond to your letters;  I hope this has not
created any problems for you.  You  first request that we
confirm that the deionization (DI)  acid that is generated
at Travenol's plant in Cleveland, Mississippi is not a
waste.  Based on the information provided,!./ we agree with
you that the DI acid is not a waste and, therefore, is not
subject to the Federal hazardous waste rules.  In particular,
before a material can be a hazardous waste, one must first
determine whether the material is a solid waste.  In general,
corrosive materials that are neutralized are normally considered
wastes.  However, where such corrosive materials can be
shown to: (1) meet relevant specs with regard to contamination
levels, (2) be as effective as the  virgin material for which
they substitute/ and (3) be used under controlled conditions,-
we believe such materials may not be wastes.  The information
provided in your letters clearly indicate that the DI acid
generated at your Cleveland plant is benefically reused and,
therefore, is not a waste.  As a result, this material is
not subject to the Federal hazardous waste rules.  This
material would be subject, however, to any state regulations.

     With respect to your request regarding the exclusion
and whether it applies retroactively under the old regulations,
we believe that since the DI acid has  always been benefically

recycled and since this acid is neither listed nor a sludge.
this material is not now (and has never been) subject to
regulations.  Therefore, Travenol does not need to go through
closure for this impoundment; we have discussed this inter-
pretation with our Office of General Counsel and they agree.
Finally, you requested written explanation as to why no
hazardous waste permit is required to dispose of the alcohol
to the drain; a verbal response was provided to you by
Ms. Irene Homer.  A written response, however, has been
prepared and should be sent to you shortly.

Dear Mr. Neiderkofler

     As we discussed last Friday, the National Association
of Photographic Manufacturers  (NAPM) provided data  to the
Agency to indicate that used x-ray  films/  in and  of them-
selves, do not appear to be hazardous under RCRA.   Therefore,
used x-ray films are probably  not subject  to the  Federal
hazardous waste management regulations  (see enclosure.)
You should be aware, however,  that  each generator is still
responsible for making this determination.A/  In  addition,
wastes not hazardous under EPA's regulations may  be hazardous
under authorized State programs*  You,  therefore, need to
contact the States to determine the regulatory status of
these films under their program.

     Please feel free to give  me a  call if I can  be of any
further assistance; my telephone number is (202)  475-8551.

                                Sincerely,

 I/   If  the generator determines that these films are hazardous,
     the only requirements  under the Federal regulatins imposed
     upon  the generator  would bo to get an identification number
     and to comply with  the uniform hazardous waste manifest.

Dear Senator Leahyi

     Thank you for your letter of May 7, 1986, regarding an
inquiry from your constituents in Bristol, Vermont.  You
requested information regarding residues from municipal waste
resource recovery facilities and any federal laws that apply
to the disposal of these residues.

     Solid residues froa municipal waste combustion (MUC)
processes consist of  fly ash and scrubber sludge recovered from
air pollution control equipment, and bottom ash.  Disposal of
these residues is. accomplished by landfilling.  Ply ash as well
as other residues from MWC processes sometimes exhibit the
characteristics of hazardous waste and, therefore, are regulated
under the applicable  disposal standards in 40 CFR Parts 260 through
2€5.  Other than those occasions when the wastes meet the definition
of hazardous waste* the Federal regulations that apply to the
landfillinq of any nonhasardous solid wastes, including most
residues from MWC processes, are the 'Criteria for Classification
of Solid Haste Disposal Facilities and Practices" (40 CFR Part
257), which were promulgated on September 13, 197t, under authority
of the Resource Conservation and Recovery Act (RCRA).  The Criteria
include general performance standards that are used to determine
which solid waste disposal facilities and practices pose a reasonable
probability of having no adverse effects on human health and the
environment*  a, copy  of these standards is enclosed for your
information*-
     The Iff4 Hazardous and Solid Haste Amendments  (HSWA) to
RCRA require the Environmental Protection Agency  (EPA) to
complete several new efforts with regard to  solid waste disposal,
By November 8,  1917, EPA must complete a study and  report to
Congress on nonhasardous waste land disposal facilities and
practices to determine whether the current Federal  Criteria

-------
are adequate to protect human health and the environment.  . In
addition, by March 31, 1988, EPA  must revise the current Criteria
(40 CFR Part 257) for disposal  facilities,  including municipal
waste landfills, that receive household hazardous waste and
small quantity generator hazardous  waste.   HSWA also requires
the Agency to develop a report  to Congress  and guidelines on
dioxin emissions from municipal waste incinerators or resource
recovery facilities.

     In response to these HSWA  mandates, we have recently
initiated several projects  in an  effort to  address problems per-
tinent to your inquiry.  EPA is currently developtaf a technical
information document for use by State and local government* in
evaluating municipal waste  combustion projects.  We anticipate
that this document will be  available in February 1987.  The EPA
contact for this effort is  Stephen  Greene,  (202) 382-4608.

     We are also currently  engaged  in a comprehensive study to
determine the characteristics of  ash from MWC processes and to
assess the potential health and environmental impacts from the
disposal of these residues.  The  results of this study will
be incorporated into the February 1987 information document
mentioned above.  The Agency contact for this ash study is
Gerri Dorian, (202) 382-4688.

     Your letter presented  several  questions regarding this
matter*  I have specifically addressed each of then below.

     1.  Has EPA tested the wastes  from municipal waste
         resource recovery  facilities to determine the
         characteristicsof such  wastes?  If so, whatdid
         those tests find?  Have such wastes ever been
         characterized as hazardous?

     Various agencies, domestic and foreign, have performed a
range of analyses on these  residues.  A list of technical papers
available to the public is  enclosed for your information.  EPA
will not complete its full  evaluation of this until February
1987.  However, it is Known that  ash residues  (predominantly fly
ash) sometimes exhibit the  characteristic of EP toxicity as
determined using the RCRA Extraction Procedures  (EP)  for toxicity
(40 CFR Parts 260.20 and 260.21), because of the presence of
certain inetals, such as lead and  cadmium.  If a waste is charac-
terized as L'P 'ioxic, it. is  a  TICRA hazardous waste.  Additionally,

-------
     2.  Do EPA's tests for toxicity of the waste include
         a full range of organic chemicals"?

     The EP toxicity test (40 CFR Part 261.24) addresses eight
inorganics and only six organic constituents.   These organics
include:  Endrin, Lindane, Methoxychlor, Toxaphene,  2,4-D,  and
Silvex.  EPA is currently developing a new toxicity characteristic
and associated leaching procedure (TCLP) that will result in the
evaluation of a broader range of organics.  For further information
on the TCLP,  your constituents should contact Todd Kimrael at
(202) 382-4795.

     3.  If the waste were determined to be a hazardous waste/
         what requirements would apply to a landfill in which
         the waste is disposed?

     Owners and operators of hazardous waste landfills must
comply with all applicable requirements in 40 CFR Parts 260
through 265.

     You should be aware that certain States have more stringent
or specific standards for the disposal of MWC ash, whether or not
the ash is classified as a RCRA hazardous waste.  The State of
Vermont has proposed regulations that address the disposal of
MWC ash.  For further information on the State of Vermont regula-
tions (existing and proposed), your constituents should contact:

             Montpelier, Vermont  05602
             (802) 828-3395

     4.  Under the Clean Air Act, are there any authorities
         for controlling the blowing dust particles that
         may result from the disposal of these wastes?

     Under the Clean Air Act, the Agency has the general authority
to investigate and regulate emissions,  including particulate
emissions, from various sources that may pose a threat to human
health  or the environment.  The Agency  also has authority under
RCRA to control dust.  For your general information, the State
of Delaware has experienced some dust control concerns regarding
municipal waste combustor residues.  For more detailed information
on the  approach Delaware has used, your constituents may wish to
con", act:

                (302) 736-4781

     5.  Under the Clean Water Act or any other water*-
         related federal statutes, are there any authorities
         for controlling leaking ground water from a landfill
         in which such waste is deposited?

     The Clean Water Act does provide EPA some authority for
ensuring ground-water protection, but these authorities are
less specific to this purpose than those delegated under RCRA.
EPA's primary authority for ground-water protection at active
landfills is derived from RCRA.  For more detailed information
regarding these Federal authorities, your constituents should
contact our Office of General Counsel, either Dov Weitman at
(202) 382-7703 or Ken Gray at (202) 382-7706.

Dear Mr. Drew:

     This letter is in response to yours dated June 12,  1986
which torwarded information concerning your company's
electrolytic silver recovery eouipment.

     The high recovery rates attributed to your equipment are
indeed impressive.  I wish you success in marketing this
equipment.

     Regarding your request tor information about CPA
limitations on silver discharges to sower systems, I am
unable to comply.  I believe you may have some misunderstanding
ot EPA regulations concerning silver, which I will attempt
to remedy.

     As you are probably aware, the EPA has established a
limit of 0.05 mg/1 of silver in public drinking water supplies.
Drinking water containing concentrations of silver above this
limit are considered to be unsafe.

     Under EPA's hazardous waste program, pursuant to the
Resource Conservation and Recovery Act (RCRA), materials
which have a silver concentration of 5 rag/1 or hiqher in
the liquid phase or in an extract from the solid phase
are considered hazardous waste and are subject to handling
and disposal regulations.  However, these regulations do not
restrict th« discharge of hazardous waste to the sewer.

     Discharge of materials to the sewer is regulated by the
Cl«an Water Act (CWA) through £PA's Effluent Guidelines
Program.  Generally, EPA Effluent Guideline regulations are
industry and process specific.  In the case of photo-finishing,
the Agency has not, as yet, issued a regulation to limit the
discharge of used photographic fixers to the sewer.  The
decision to delay issuance of such regulations is based, in
part, on the Agency's belief that current silver recovery
practices greatly reduce silver discharges to the sewer.

-------
     There are EPA regulations limiting silver discharges to
the sewer fro» metal finishing and electroplating operations.
These silver concentration limits are below 1 rag/1.

     If you desire additional information of EPA effluent
guidelines, I suggest that you contact Marvin B. Rubin
(mail code WH-552) in EPA's Office of Water Regulations and
Standards.

     Also for your information, in case you don't already
know, there is a trade association of photographic equipment
manufacturers, in tho United States.  You can contact this

Results

1.  Quantity of Waste Generated

     Table 1 conpares the salient statistics for six primary
nonferrous Smelting and Refining (S*R) sectors (1984) against
the OSW 1982 TSD General Survey for manufacturing facilities.
In tens of average vast* per generator, the SfrR's other than
have a significantly lower mean (6,200 vs. 62,5OO wetric tons
per year per facility) than that for all manufacturing.  On the
other hand, S&R's also exhibit a substantially higher median
(3,800 vs. 300 tons), indicating that they typically fall above
the median sixe among generators.  However, 90 percent of these
S&R's generate less than 25,000 tons per year, which is about on
a par with the manufacturing sectors as a whole.  Excluding Ti02»
the largest individual generators within these six SfcR sectors
produce characteristic wastes in the 30,OOO to 36,OOO too per
year range, cojspared with several million too* per year for the
largest individual generators in soae other sectors.  Statistical
estimates based on the TSD general survey indicate that there
were about 250 manufacturing facilities in other sectors generating
in excess of 36,000 tons per year in 1981*

     In summary, two conclusions can be state-It

          (1) Most primary nonferrous S&R facilities that
              generate characteristic hasardous waste
              produce larger quantities than do a majority
              of facilities in other sectors, but

          (2) SfcR generation rates are not extremely large in
              comparison to the larger waste generators in
              other sectors*

     Titanltta dioxide would constitute .an exception to these
findings*  Mates of characteristic hazardous waste generation
for the generators in this sector are equivalent to the 35th to
99th percentiles of all waste generators.

     What if all hasardous waste except for aluminum potliners is
considered characteristic waste?  The table below provides a
brief cooperison with the addition of copper to the list of
sectors.

         Essentially, the transfer of proposed listed wastes to the
    "characteristics* category does not change the conclusions.  It
    adds a sector with substantial waste quantities (copper) and adds
    additional characteristic wastes to several facilities in the
    lead and sine sectors.  However, it only increases by four the
    number of facilities with wastes in excess of 30,OOO tons per year.

    2'  'fhat if "Large Volume" isdefined in ter^s of Sectors  (industry
        groups) instead ofin^£vidual facllilties?

         The 1982 TSD Generator Survey was analyzed in terns of
    individual four-digit Standard Industrial Classification (SIC)
    industry hazardous waste management quantities.  Coniparisons were
    then drawn between the 194 manufacturing sectors represented in
    the survey and seven of the larger nonferrous metal smelting and
    refining (S&R) sectors studied in the reinterpretation.

    Sector Totals

         The largest hazardous waste generating Sfctl sector was cooper
    with 360*000 metric tons oer year.  Thirty-two (32) other  individual
    manfacturing sectors  (16 percent of all sectors) in the Office of
    Solid Waste 1983 Mail Survey reported larger hazardous waste
    quantities than copper.  The second largest S&R sector in  our
    sample of seven was aluminum with 104,000 metric tons oer  year
    (excluding potliners).  Forty-eight (48) other manufacturing
    sectors* or 23 percent of all sectors, exceeded 104,000 tons per
    year of total haardous waste.  The average sector total for all
    seven 3&R sectors was also about 104.000 tons per y«ar.

-------
     The smallest StR sector among the seven in terms of estimated
hazardous wast.* was titanium metal with 11/000 tons per year.
This was exceeded by 109 (56 percent) other manufacturing sectors
and, in turn, was larger than 85 (44 percent) of the other non
S&R sectors.

     On the basis of these data, we conclude that the smelting
and refining waste quantities when viewed as sector totals are
well within the "normal" range of sector hazardous waste quantities
for all manufacturing categories.

3.  Population and Proximity to Public Water Supplies

     Smelting and refinery facility locations were compared to
locations of other generators based on the 1982 generator survey
(HWDMS).  Two types of comparisons were perfornedt

          ' Population density in the vacinity of the
            facility (one and five mile radius)
Population served by public water supply intakes
located within one and five ail* ra
                                               uppl
                                               dii.
     Non ferrous smelting and refining sites are sonewhat more
rurally located than other generators.  Aver* je population living
within one mile for SbR's was 4,500 vs. 11,800 for other generators;
and within five miles average population was 51,000 vs. 198,000.
The conclusion is not warranted, however, that S6R's are mainly
located in remote areas)  75 percent of S&R'a have a population
of at least 7,500 within a mile, compared with 15,000  for other
generators.

     Regarding distance to public water supply intakes, 59 percent
of S&R's showed a public water supply intake within one mile,
vs. only 40 percent of all generators in the OSW  generator survey.
Both SfcR's and all generators showed a public water supply intake
within fiv« Miles for every facility in the respective samples.
On average, the water supply systems near S&R's served somewhat
smaller popalations (2,500 vs. 5,000 for systems  with  intakes  located
within a avila of the facilities).

Dear Mr. Alff:

     I enjoyed meeting you and getting the chance to discuss your
company's xero-headspace extractor (ZHE) during the OSW symposium.

     The  EPA has tentatively decided to add your ZHE to the list
of extractors deemed suitable for conducting evaluations of
volatiles.  He would like to remind you that your device, as well
as others, is in a proposed status as the rules that specify use
of the TCLP have not yet been finalized.  If we encounter any
information which leads us to change our evaluation, we will let
you know.  Otherwise, you can expect that your extractor will
receive formal approval when the TCLP is finalized later this year,

     If you have any questions, please call me at (202) 475-6722.

Dear Senator Cranston:

     Thank you for your August 4, 1986, letter on behalf of
your constituent, Mr. Martin Schlaegel, concerning the disoosal
of dry cell batteries containing mercury and the potential
damage they may cause to the environment.

     We, like Mr. Schlaegel, are concerned with the toxic
effects of mercury on the environment.  As you may know,
regarding dry cell batteries, the Aaency's hazardous waste
rules define hazardous as any waste where the leachate exceeds
0.2 mg/l of mercury.  Wastes are also defined as hazardous
if they are specifically listed by the Agency.  At this
time, mercury dry cell batteries are not listed as hazardous
by the Agency.  Although we have no data indicating whether
disposed mercury dry cell batteries are hazardous wastes
under our rules, we reguire generator's of such waste tc
make this determination.  To the extent that these batteries
are hazardous (i.e., the leachate from the dry cell battery
would contain greater than 0.2 mg/l of mercury), they must
be managed at a hazardous waste management facility.

     There are two exceptions to the reguirement that hazardous
waste from these batteries be managed at a hazardous waste
management facility.  First, if the batteries are discarded
by a householder, they are not subject to the hazardous waste
rules. Second, if the hazardous waste from these batteries is
generated in small quantities (defined as less than 100 kg
per month)* they also are not reguired to be managed at a
hazardous waste management facility.  In these cases, the
batteries generally would go to a municipal sanitary landfill.
Municipal landfills are non-hazardous waste facilities.
Because the Agency is concerned that discarding this type of
waste in municipal landfills could be a problem we are re-eval-
uating our non-hazardous waste criteria.  After we complete
our review of the criteria, we will revise the regulations
for non-hazardous waste facilities, including municipal
landfills.  Me will issue these regulations in March of 1988.

Dear Jacquier

     As per our phone conversation of September  4,  1986  con-
cerning your glass fiber filters, both  David  and Todd  will
not reconsider the ERCO study results.  They  still  feel
that your filters do not have the durability  required  for
the rigors of the TCLP.  These filters  have a tendency to
become frayed around the edges while undergoing  the pressures
of the test.  This could contribute to  irreproducibilityand
may cause confusion amoung analysts.

     We therefore cannot add your filters  to  the list  of the
ones deemed suitable for TCLP purposes.  If you  have any
questions about this decision, please call me at (202) 475-6722.

Mr. Thomas Dufficy
Executive Vice President

Harrison, NY   10528

Dear Mr. Dufficy:

     This is in response to your letters of September 15, October
24, and November 4, 1986, regarding the regulatory status of
properly washed chemical recovery cartridges  (also referred to in
your letters as steel wool cartridges), flake silver from
electrolytic recovery cells, and silver-containing ion-exchange
resins, under the federal hazardous waste rules.  These units
(i.e.. chemical recovery cartridges, electrolytic recovery cells,
and ion-exchange resins) are used to recover silver in a number
of operations in the photographic industry.

     Based on the data and information provided in your letters
(i.e.. analytical test data and discussions regarding the
representativeness of the data), it appears that when these units
are properly washed (in accordance with the instructions provided
in your letters) , they do not exhibit the characteristic of EP
toxicity for silver.  You also state that these recovery units do
not exhibit the characteristics of ignitability, corrosivity, and
reactivity, and I presume that these recovery units are not EP
toxic for any of the other toxic contaminants.  Thus, those
recovery units that are properly washed appear not to be
hazardous wastes and, therefore, are not subject to the federal
hazardous waste regulations.  However, each generator is still
responsible for determining whether or not the wastes contained
in the recovery units are hazardous.  See 40 FR §262.11.

     In addition, as we've discussed previously, to the extent
that these recovery units would be defined as a sludge  (i.e.. a
pollution control residual), they would not be subject to the
federal hazardous waste rules when they were sent for
reclamation, since they would not be considered a solid waste.
Thus, if any of these devices was used to treat wastewater  (for
example, to comply with the new BAT/PSES rules), the residues
contained in the units would be considered a sludge; if the
sludge is sent for reclamation, it would not be considered a
solid waste.  See 40 CFR §261.2(c)(3).
        This has been retyped from the original document.

-------
     Finally,  as you are aware,  States may choose to regulate
these recovery units under their State hazardous waste program
differently than under the federal program.   Therefore,
representatives in the various States will need to be contacted
to determine the regulatory status of these recovery units under
the State hazardous waste rules.

     Please feel free to give me a call at (202) 475-8551 if I
can be of any further assistance.

                                   Sincerely,

Honorable Les Aspin

Washington, D.C.   20515

Dear Mr. Aspin:

     Thank you for your December  18,  1986,  letter requesting
that the Environmental Protection Agency  (EPA) make a determi-
nation as to whether  lithium  thionyl  chloride  (SOCL2) batteries
are hazardous wastes.

     As you may know, wastes  are  considered hazardous under
regulations issued pursuant to  the .Resource Conservation and
Recovery Act (RCRA) if they are either  specifically listed as
hazardous wastes or if they exhibit one of  four characteristics
(i.e., ignitability,  corrosivity,  reactivity,  or Extraction
Procedure Toxicity).  Lithium batteries are not listed hazar-
dous wastes at this time and  the  Agency is  not currently
planning to list them as hazardous.

     With respect  to  the characteristics  of hazardous waste,
determinations as  to  whether  a  particular material exhibits a
characteristic is, by regulation  (40  CFR  §262.11(c)), the
responsibility of  individual  generators.  Although th'e Agency
rendered an opinion in March  of 1984  with respect to lithium
sulfur dioxide (LI/SOj) batteries, we did so only after
repeated requests  from the Army and because there had already
been considerable  work done on  LiSO2  systems which allowed
the Agency to render  an opinion without extensive additional
study.  Further work  on other lithium battery  systems is not
currently underway and other  priorities established by the
Hazardous and Solid Waste Amendments  of 1984 (HSWA) will
preclude us from initiating such  a study  any time in the
immediate future*  Consequently,  we .suggest that the Depart-
ment of Defense, perhaps in cooperation with the battery
manufacturers, evaluate these other  lithium systems against
the characteristics in Subpart  C  of  Part  261.

     If I can be of any further assistance  in  this matter,
please do not hesitate to call.

                              Sincerely,
                               J.  Winston Porter

Dear Mr. Aniballi:

     This is in response to your letter of December  16, 1986,
in which you requested an interpretation of the regulatory
status of your liquid scintillation counting cocktail,  Bio-Safe II,
under the Federal hazardous waste regulations.

     Based on telephone conversations you had with
Miss Filooena Chau,  of my staff, and your letter of January 12, 1987,
Bio-Safe XI contains less than 0.05 microcuries of radioactive
tritium (hydrogen- 3) and carbon 14; in addition, this material
contains the following scintillators: primary scintillator of
PPO: 2,5diphenyloxazole; secondary scintillator of Butyl PBD:
2-(4'-tbutylphenyl)-5-4"biphenyl)-l,3,4 oxadiazole.

     The waste/ as you described, does not seem to be subject to
the Nuclear Regulatory Commission regulations under  10  CFR 20.306(a),
since your waste contains less than 0.05 microcuries of hydrogen-3
and carbon- 14 per gram of medium.  However, your waste  appears
to be subject to 10 CFR 20.306(d), which states that the generator
is not relieved from complying with other applicable Federal,
State, and local regulations governing any other toxic  or hazardous
property of these materials.  EPA's hazardous waste  management
regulations would be an example of such "applicable  regulations."

    Thus, you must compare the characteristics of your  waste against
the criteria outlined in 40 CFR Part 261 (see enclosure) to deter-
mine whether or not your waste is hazardous.  Specifically, you
must determine whether your waste exhibits any of the characteris-
tics of hazardous waste (see 40 CFR Part 261, Subpart C, "Character-
istics of Hazardous Waste"), or whether your waste is a listed
hazardous waste (see 40 CFR 261, Subpart D, "Lists of Hazardous
Waste").

-------
                              - 2 -

     With respect to the hazardous waste characteristics,  you
must determine whether your liquid scintillation counting cocktail
is ignitable, corrosive, reactive, or toxic.  Liquid ignitable
wastes are defined under §261.21 as those with a flash point of
less than 140*F.   Corrosive wastes are defined under §261.22 as
those having a pH of less than or equal to 2 or greater than or
equal to 12.5 or is able to corrade steel at a rate greater than
6.35 mm  (0.250 inches per year at a test temperature of 55*C (130*P)).
Reactive wastes are defined under §261.23 as those exhibiting
any of eight properties  (see the attached regulations).  Section
261.24 defines the characteristic of extraction procedure (EP)
toxicity and indicates the test methods to be used to identify
the presence of this characteristic for any contaminants listed
in Table I of the Section.

     Your letter stated  that your waste has a flashpoint of
greater than 300*F, greater than the highest flash point of
regulatory concern, 140*F.  The ingredients of Bio-Safe II, as
you described, are not any of the contaminants listed in Table I
of §261.24; thus Bio-Safe II does not seem to be EP toxic.  Your
letter did not address whether Bio-Safe II was corrosive or
reactive.  In addition,  neither liquid scintillation cojcktails
nor laboratory wastes, as a general category, are presently
listed as hazardous wastes under §261.30-.33.  Therefore,  provided
the liquid scintillation cocktail is not corrosive or reactive, it
does not appear to be a hazardous waste.

     However, each generator is still responsible for determining
whether or not their waste is hazardous.  See 40 CFR 262.11.  In
addition, you will need  to check with your State or local authorities
to determine whether this waste is regulated under their authority.

     If you have any further questions, please contact
Miss Filomena Chau (202-382-4795) of my staff.

Dear Mr. Berger:

     I am responding to your letter of August 18, 1986, in which
you request an Agency opinion that Lithium/Sulphur Dioxide (Li/SO2)
batteries that have been fully discharged to zero volts no longer
exhibit the characteristic of reactivity.  Based on information
supplied by the US Army Electronics Technology and Devices Labor-
atory (LABCOM), we generally agree that such batteries are unlikely
to be reactive.

     Under the hazardous waste regulations, each generator of a
waste is responsible for making a hazardous waste determination
under 40 CFR 262.11.  If the waste exhibits one of the four
characteristics of hazardous waste identified in Subpart C of Part
261 or is a waste listed in Subpart D of Part 261, it must be
managed in accordance with the hazardous waste regulations.  As
you know, on March 7, 1984, in response to requests from the De-
partment of the Army, EPA rendered an opinion that spent or discar-
ded Li/S02 bateries appeared to exhibit the characteristic of
reactivity* a* defined in 40 CFR 261.23.  The Agency further
noted that 264.312 and 265.312 of the hazardous waste regulations
prohibit the placement of reactive (or ignitable) hazardous waste
into a landfill unless the waste, or waste mixture, is treated,
rendered, or mixed before, or immediately after, placement in a
landfill such that the waste or waste mixture no longer exhibits
the characteristic.  Thus, the prohibition would no longer apply
if the waste no longer exhibited the characteristic of reactivity
(or ignitability).

-------
                               -2-
     The Agency continues to believe that  fully charged and duty-
cycle Li/S02 batteries are reactive hazardous wastes and should
be managed as such.  However,  information  provided by LABCOM
during the Augtsk 5 meeting with members of my staff and in your
follow-up submission of August  18th indicates that a Li/S02
battery that has been fully discharged to  zero volts would contain
substantially reduced quantities of reactive materials such that
the battery is not likely to exhibit any of the properties of the
reactivity characteristic.  We  assume that by fully discharged,
LABCOM means that each cell within each battery will have been
discharged.

     It is our understanding that the mechanism by which the Army
intends to effect discharge of  all Li/SO2  batteries to zero volts
would be through a battery redesign that would incorporate an
additional resistor circuit that would be  activated by an external,
manual switch.  While such an  approach would appear to.be capable
of producing the desired results, it remains the  responsibility
of the generator or the disposer to ensure that all batteries so
discharged have in fact reached a fully discharged state and, thus,
are no longer reactive.

     In conclusion, the Agency  agrees that a Li/S02 battery which
has been fully discharged is unlikely to exhibit  the characteristic
of reactivity.  However, the responsibility for determining whether
a waste exhibits a characteristic of hazardous waste either before
or after treatment still remains with the  generator and treatment
or disposal facility.

                               Sincerely,

Honorable Robert Walker
U.S. House of Representatives
Washington, O.C.  20515

Dear Mr. Walker:

     Thank you for your March 5, 1987 letter regarding your
constituents' Carol and Richard Kushner concern about incinera-
tion.  Generally speaking, EPA considers combustion to be a
viable alternative to direct landfilling as a means of managing
municipal waste.  We recognize, however, that concerns have
been raised about certain aspects of combustion facilities,
including the disposal of residual £siu

     The solid residues from municipal waste combustion consist
of bottom ash, fly ash from air pollution control equipment,
and miscellaneous debris from uncombustible materials.  Because
these residues can contain potentially toxic metals, proper
disposal practices are important.

     The presence of large amounts of such metals could cause
ash to be classified as a hazardous waste.  One way to determine
whether a waste must be managed as a hazardous waste is to
perform what is referred to as the 'extraction procedure (EP)
toxicity test", which determines the concentrations of metals
that are likely to leach out of the waste when placed in the
type of weakly acidic environment typical of a landfill accept-
ing (unincinerated) municipal garbage.

     In 1986, EPA performed a search for published reports of
the results of EP tests on ash to see what the results of those
tests typically showed.  These tests had not been scientifically
reviewed, and some of the results were several years old.
The results indicated that fly ash may exhibit the EP toxicity
hazardous waste characteristic, however, when combined fly
and bottom ash was tested.  This combined ash frequently did not
exhibit a hazardous waste characteristic.  EPA recently ini-
tiated a study of the characteristics and leachability of ash
from municipal waste combustion to address these issues in a
more complete and careful fashion.  Following EPA's evaluation
of ash characteristics, the Agency will be in a position to
evaluate what types of management practices are most appropriate

-------
     If ash residues are found to routinely contain sufficient
amounts of metals to be of concern, there are a number of
technical measures that may be appropriate for their disposal.
First, basic housekeeping practices can be used to cut down on
the wind dispersal of ash.  Second, the common approach of
mixing the acidic fly ash with the alkaline bottom ash to
achieve a buffering effect will decrease the tendency of the
ash to leach metals.  (Acidic conditions tend to enhance the
leachability of metals).  Third, some design and location
practices can reduce the tendency of ash to leach or limit the

extent to which leachate would affect groundwater.  Monofilling,
which is the disposal of ash in a landfill that accepts nothing
else, can keep the ash: segregated from acids or materials
which produce mild acids when they decay.  Also, covers can be
designed to minimize rainwater infiltration and proper siting
of ash landfills can limit contact of the landfill with ground-
water.

     EPA is also evaluating other aspects of municipal solid
waste management.  Later this spring, EPA will submit to Congress
a report on air emissions from municipal waste combustion
facilities.  Additionally, EPA is reviewing its program in the
general area of solid waste disposal, and will be proposing
rules, sometime in 1988 to improve disposal of solid waste at
municipal landfills to protect health and the environment.

     If I can be of any further assistance, pleas* let me know.

Dear Mr. Bumgaraert

     This bri«f not* will respond to your latter of inquiry to
David Friedman regarding the interpretation of the Characteristic
of Ignitability, 40 CF* Part 261.21.

     Your queetiona are repeated below with the appropriate
responsei

     o  We have observed apparent flashes on solvent mixtures
        whose composition would imply they are nonflammable,
        i.e., 99% Preon 113 mixtures containing t?ece levels of
        cyclohexane.  The flashes occur at low temperature  (20*
        - 40*C) and are usually not reproducible on the same
        aliquot.  Should these initial flashes be reported as
        true Flash Points for RCXA characterisation?

        Yes, according to the present regulations.

     o  Many solvent mixtures, including Preon 113* boil at
        temperatures below 60*C and cannot be properly evaluated
        by Pensky-Martens.  Row should such RCRA data be reported
        to agencies and other clients?

        Only those liquids that flash are considered ignitable.

     o  Many clients request Plash Point data for soils and
        other solid materials*  They indicate that waste haulers
        or state or Federal agencies are requiring such data.
        Does EPA have a standard policy on this matter?

        Current teet methods  (40 CPU Part 2*1.21) are designed
        for liquids only.  At the preeent time there are no
        suitable,  validated procedures  for determining the
        ignitability characteristic of  solid  (non-liquid)
        wastes.

     We hope these answers are  sufficient for your use.   If you
have additional questions please  feel free to call us.

2.  Solvent Drippings  front Decreasing Operations
    A Dall-bearing rrenufacturer dips metal paxts in a degreasing tank of
    pure 1,1,1-trichloroethane.  Once the parts nave been dipped, they
    are ground.  The cooling system (either oil or water is used as the
    fluid)  picks ups the grinding sand, metal flakes, and traces of
    solvent left on the part.  The fluid is then filtered for reuse, and
    the sand-metal-solvent mixture is discarded.  Are the traces of
    solvent left on the parts after degreasing classified as F001?  Is
    the sand-metal-solvent mixture regulated as a hazardous waste when
    discarded?

         The small amount of solvent retraining on the part after it has
         been dipped will not be regulated as FOOl.  If the sand-metal-
         solvent mixture exhibits any of the characteristics of hazardous
         waste as defined in Subpart C of 40 CFR Part 261, then the
         mixture would be regulated as a hazardous waste.

Dear Mr. Whitehead:

    I am responding  to your letter of May 4, 1987, to Mr. Alan
Cor son requesting confirmation  of  your  interpretation concerning
the regulation, under the  Resource Conservation and Recovery Act
(RCRA) , of containers that packaged urethane coating chemicals.

    Specifically, you stated that  since none of the chemicals
used in your two-part urethane  coating  system are currently
listed as "Pn or "U" wastes in  40  CFR 261.33, th« residues in the
containers are not hazardous wastes and, therefore, you- vould not
need to determine whether  the containers are empty in accordance
with 40 CFR 261.7.

    Your interpretation  is partially correct.   Pert 261c7 deals
with any hazardous waste residues  left  in containers, not just
the commercial chemical  products listed in Part 261.33  (or those
hazardous wastes listed  in Parts 261.31 and 261.32).  Therefore,
it also will be necessary  to demonstrate that the container
residues do not exhibit  any of  the hazardous waste
characteristics (ignitability,  corrosivity, reactivity,  or
extraction procedure (EP)  toxicity)  before stating that the
residues are not hazardous.  If the residues, in fact,  are
hazardous (i.e. . they exhibit a hazardous waste characteristic)
then Part 261.7 should be  used  to  determine whether the container
is empty.

    If you require additional information, please contact Ed
Abraas at (202) 382-4787.

Dear Ms. Eglinton:

     The Third Edition of SW-846 requires that the method of
standard editions be used whenever  the  percent recovery of a
matrix spike is outside of the  range  75% to  125%.  The method
of standard additions consists  of "spikes" of three different
levels of analyte into three aliquots of the sample to correct
for interferences.  This requirement  applies to analysis.by
both atomic absorbtion and ICP.

     However, it should also be pointed out  that the method
of standard additions is required,  in all cases, when analyz-
ing Extraction Procedure toxicity extracts (see 40 CFR 261,
Appendix II).

     Thank you for your kind remarks  about the Third Edition
of SW-846.  We welcome any suggestions  that  you might have
for further improvements.  I hope this  aleviates your concerns

Dear *!r. tfonson:

     As you requested, durino our recent tclenhone conversation,
I air writincj to review the reoulatory status of Nethod  1310
(Extraction Procedure) and Method 1330  (Extraction Procedure
for Oily Waste.

     when testinn a waste to determined if it exhibits  the
characteristic of Extraction Procedure Toxicicy one employe
Method  1310.  This is so even if the waste would be conridered
to be an "Oily Waste".  The Agency proposed the Extraction
Procedure for Oily Waste on October 1» 19«4 (49 Federal Register
3S, 766 and to replace Method 1310 with th<» new Toxicity Charac-
teristic Leachino Procedure, see January 14, 1986  (51 Federal
Pcnist?r 1602) and June 13, 1986 (51 Federal Register 21, 642).
This chana*4 has not yet been promulgated.  Method  1310  remains
the designated acceptable procedure (see 40 CFR 261.24).

     The Aoency however has been concerned that Method  131C
moat not adcouately n«or!el the potential leachability of toxic
species fror certain listed oily wastes.  Method 1330,  therefore,
was developed as a worst ease estimation of potential toxicant
release.  For deli*tino petition evaluation purposes, it serves
as a conservative indication of the mobile rnetal fraction.  The
nohila metal concentration (MHC) values are compared with de-
listing thresholds developed using a specially developed fate
and transport rnodcl.

     In summary, under the RCRA requlatory program, Method 1310
is the only method currently approved for use in identifying
wastes that exhibit the characteristic of Extraction Procedure

you and trust this clarifies the status of Methods 1310 and
1330.

  Dear Mr. Lueck:

       This is in response to your July 13, 1987,  letter requesting
  an interpretation of whether and how the EPA hazardous waste reg-
  ulations apply to vehicle filters contaminated with pesticides.
  For  the use you describe, i.e./  in farm equipment,  it would seem
  most likely that the filters would become contaminated with pest-
  icides via contact with ambient  air near application areas.  As
  such,  the filters do not really  contain waste pesticide.   Rather,
  the  spent filters are themselves a waste that may contain pesticide
  ingredients as constituents.  The generator of any waste  must deter-
  mine whether his waste is hazardous waste, and if it is,  must com-
  ply  with applicable regulations.  Most likely, these fiters would
  only be hazardous if they exhibit the characteristic of E.P.
  toxicity.  (See 40 CFR S261.24.   I have photocopied and enclosed
  the  relevant pages of the regulations for your information.)

       You should also note that generators of less than 100 kilo-
  grams (about 220 Ibs.) of hazardous waste per month are condition-
  ally exempt from regulation.  (See 40 CFR S261.5.)   Many  farms,
  if the filters are hazardous waste at all, may be eligible for
  this conditional exemption.   You might advise customers to deter-
  mine the apount of hazardous waste they generate each month inclu-
  ding the filters in the amount,   if the farmer's monthly  total is
  below 100 kilograms, the waste may be sent to a municipal landfill.
  If the total exceeds 100 kilograms, the farmer may then want to
  have the filters analyzed to determine if they exhibit E.P. tox-
  icity.

Dear Dr. Edelstein:

     This is in response to your letter of May 1, 1987, in
which you requested an interpretation of the regulatory status
under the Federal hazardous waste regulations of your liquid
scintillation cocktail, Scintiverse BD, if disposed.

     Under 40 CFR Part 261, a waste can be determined to be
hazardous in one of two ways.  Specifically, as defined in
Subpart D, a waste could be a RCRA listed waste, or a waste,
according to Subpart C, could exhibit one or more of the
characteristics of a hazardous waste (ignitability, reactivity,
corrosivity, or toxicity).

     It is clear from the information you provided that your
material is not a RCRA listed waste.  See 40 CFR Part 261,
Subpart D.  However, the data did not provide the Agency with
enough information to determine if the material would or
would not exhibit one or more of the characteristics of a
hazardous waste.  It must be pointed out that, under 40 CFR
S262.ll, waste generators are responsible for determining
whether or not their wastes exhibit one or more of the hazardous
waste characteristics.

     With respect to the hazardous waste characteristics, you
must deteraine whether your liquid scintillation cocktail is
ignitable, corrosive, reactive^ or toxic.  Liquid ignitable
wastes are defined under S261.21 as those with a flash point of
less than 140*P.  Corrosive wastes are defined under S261.22 as
those having a pH of less than or equal to 2 or greater than or
eaual to 12.5, or that are able to corrode steel at a rate greater

-------
                            - 2 -
than 6.35 mm  (0.250  inches) per year at a test temperature
of 55°C  (130°F).  Reactive wastes are defined under S261.23  as
those exhibiting any of eight properties (see the enclosed
regulations).  Section 261.24 defines the characteristic of
extraction procedure (EP) toxicity and indicates the test methods
to be used to identify this characteristic.

     You should also note that the Agency has proposed a new
leach procedure, the Toxicity Characteristic Leaching Procedure
(51 FR 21648, June 13, 1986).  When this proposal is finalized,
waste generators will be responsible for determining whether
their wastes meet this characteristic.  In addition, you will
need to check with your State or local authorities to determine
whether this waste is regulated under their authority.

     If you have any further questions, please contact Filomena
Chau of my staff at  (202) 382-4795.

   Dear Mr. Gock:

        The following information is being provided in response to
   your letter of April 6, 1987,  regarding the definition of aqueous
   as used in the Corrosivity Characteristic/ 40 CFR Part 261.22UX 1),

        As you are aware, the corroaivity characteristic docs not
o  specifically define what constitutes an aqueous waste.  However,
£  we have developed guidance in  defining the ter» 'aqueous.*  In
 i  particular, we consider a waste to be aqueous if it ha* a lictuid
%  phase containing more than 50  percent water.'  (See attached letter
*^  from Dr. John Skinner, Director of the Office of Solid Waste, on
oc  February 26, 1995.) This position is currently in effect and you
^  should use the 50 percent water cut-off as a basis for evaluating
™  whether or not to test your wastes for corrosivity.

        I should point out that we are considering reviewing this
   position, as well as the need  for a regulatory definition of
   aaueous waste.  Therefore, you should be aware that a regulatory
   definition of aqueous may be proposed at some point in the
   future.

        If you have any additional Questions, please do not hesitate
   to contact me.

     hexavalent chromium,  dropped from  the third  edition  of
     EPA'a  "Test  Method  for  Evaluating Solid Waste?"    Is
     there a replacement method?

          The SW-846 Test Method  #3060 is  used to determine
          the total concentration of hexavalent chromium  in
          solid  waste.    It  uses  a basic digestion of the
          waste sample to solubiiize both water-insoluble and
          water-soluble hexavalent chromium compounds.

          Method 3060  was dropped  from the third edition  of
          the SW-846  Manual because  it yielded inconsistent
          results  from  sample  to  sample  within  the  same
          matrix and from matrix to matrix.  The  method  also
          provides the  analyst with no way of distinguishing
          when it would or would not work.

          An evaluation study of  Method 3060  indicates  that
          not only  is it  possible to  oxidize Cr*3 to Cr**,
          but  that  Cr*"  can  be  reduced  to  Cr*3  during
          digestion.   In fact, there is more likelihood that
          Cr**  is reduced than Cr*3  oxidized.   A",so during
          the  digestion,  precipitates  are formed which can
          present problems.

          It may  be  appropriate  to  continue  using Method
          3060,  provided  the  user  can demonstrate that it
          works by doing spike recoveries.  At this   time EPA
          does  not  have  a  current or expected replacement
          method for Method 3060.

4.   Natural Gas Pipeline Condensate and EnergyRecovery

     Is natural gas pipeline condensate that exhibits the
     characteristic of ignitability and that is going to be
     burned for energy recovery a hazardous waste?

          According to the January 4,  1985 FR page 630, off-spec
          fuels burned for energy recovery are not by-products,
          thus are not considered wastes.   This includes natural
          gas pipeline condensate.   The condensate contains many
          of the same hydrocarbons found in liquified natural gas
          and certain higher hydrocarbons that have energy value.
          It is generated in the pipeline transmission of natural
          gas and is not considered to be a by-product nor a
          waste when burned for energy.

          By-products that exhibit any characteristics of
          hazardous wastes are, however,  hazardous waste when
          burned for energy recovery.

MEMORANDUM

SUBJECT:   Appropriate leaching test to use in evaluating soils
           contaminated with lead.

DATE:      October 30, 1987

FROM:      David Friedman, Chief
           Methods Section (WH-562B)

TO:        Thomas Spittler, Chief
           Laboratory Branch, Region I


     As you requested, I am writing to  review the regulatory
status of the various leaching tests that have been developed
for use in the hazardous waste program  with respect to the
problem of assessing the regulatory status of contaminated
soils.

     When evaluating a soil, or other waste, to determine
whether it is a hazardous waste by reason of the toxicity
characteristic one should use Method 1310, the Extraction
Procedure.  While, sometime  in the future, we expect to  replace
Method 1310 with the new Toxicity Characteristic leaching
Procedure  (TCLP) , the TCLP has not yet  been promulgated  for  such
use.

     As I  indicated at the recent meeting  in Annapolis of the
Regional laboratory chiefs,  OSW has  recently developed Method
1312 for use  in evaluating the  leaching potential  of  in-place
soils and debris.  This test, which  is  a modification of the
TCLP, employs regional specific  simulated  acid  precipitation as
the extraction medium. As you recently  noted  in your  work on
neutral soils contaminated with lead, the  high  acetate
concentration of  the  TCLP relative to the  EP means that  the TCLP
is significantly more aggressive than the  EP  for such materials.
For this,  and other  reasons, OSW feels  that use of the TCLP for
             the  greund water GQ&kni9&ion of  soils ^

closure getenninations,  and on facility investigations,  the

     I hope I have clarified the use of the different methods
for you.  I want to thank you for calling my attention to the
problem you faced when the TCLP was applied to the contaminated
soils in your area.  I am sorry that I did not get a chance to
see you in Annapolis last week.

     Dear Mr. cox:

         This is in response  to  your  letter  of  October  7,  1987, to
     Matthew Straus concerning previous correspondence  from my office on
     recycling of zinc oxide  baghouse dust.   In your  letter you request
     that the Agency clarify  whether  a sludge (zinc oxide) is subject to
     subtitle c when used to  maxe  fertilizer.   I apologize if Matt and
     my previous letters  to you  and Mr. Tate were not entirely clear.

         The rule that applies in  this situation is that the determina-
     tion of whether a material  is a  solid waste depends on the ultimate
     management of the material.   (See 50  EB 634; January  4, 1985.)
     Certain ultimate management methods,  including incorporation of
     waste  into products  that are  to  be placed  on the land, result in
     designation of the material as solid  waste.  Therefore, if zinc
     sulfate is recovered from the zinc oxide and then  used to produce
     fertilizer, the zinc oxide  is a  solid waste.

         The dust in question has  not been listed as  a  hazardous waste;
     therefore, it would  be hazardous only if it exhibits  one of the
     characteristics at 40 CFR Part 261, Subpart C.   It is the gene-
     rator's responsibility to use his knowledge of the waste or to
     perform the tests described in sections 261.22-24  to  determine
     whether the waste exhibits  any of the characteristics of hazardous
     waste.  The solution that you propose (i.e. , to  regulate the
     process until the metals are  removed) is allowable; but the issue
     is not when the material ceases  to be a solid waste,  it is rather
     when does it cease to exhibit a  characteristic.

         Finally, you should  note  that a facility which treats a
     hazardous sludge to  recover a material  (i.e.f zinc sulfate) that is
     used to produce fertilizer  is subject to 40 CFR  section 261.6(c),
     the requirements for hazardous waste  recycling  facilities.

SUBJECT:  Pulverizing Waste Prior to EP Test

FROM:     Scott Maid
          Variances Section

TO:       Carolyn Bosserman
          SAIC

       Linda Cessar and I discussed the "pulverizing" issue you raised
concerning Eli Lilly (#564A) and we reached a consensus that the metal
rings and lids should be included in the ash samples.  Our justification
for this is that these materials are contained within the volume of
hazardous waste, and should be evaluated as such.  HSWA requires such an
evaluation of other constituents and factors in our evaluation of
hazardous waste.  Also, the EP toxicity test procedure in 40 CFR Part
261, Appendix II explicitly requires that solid wastes shall be evaluated
for particle size, and large pieces of waste should be ground up,
crushed, or cut until the waste will pass through a 9.5 nun sieve.  This
regulatory requirement is quite important since it does not allow  for the
waste in question to be separated into different sized particles prior to
testing.

       The 9.5 mm sieve will still allow pieces of metal over 1\3"
square to pass through it, which are really pretty large chunks.   The
connotation of "pulverizing" implies reducing the metal chunks to  povder,
which we agree is inconsistent with the requirements of the EP toxicity
test procedure.  If the paragraph about the sampling of ash were
re-worded to specify that the waste ash (including metal rings and lids)
should be crushed to a uniform particle size in accordance with the  EP
test requirements, then it may not be perceived to be a problem by Eli
Lilly.

       Call me if you have questions.

MEMORANDUM

SUBJECT:  Lead-3ased Paint Residues  and  Lead Contaminated
          Residential Soils in Private/Public Housing units

FROM:     Jeffery Denit, Deputy Director
          Office of Solid Waste (WH-562)

TO:       Walter Kovalick, Deputy Director
          Office of Emergency and Remedial Response  (WH-548)
     The following information is being provided in response to
your draft memorandum requesting classification of lead-based
paint residues.

BACKGROUND

     As you are aware, the question of lea :-based paint dis-
posal has been of concern for a long time.  AS early as 1904, it
was recognized that ingestion of paint and  paint chips poses a
serious health hazard to children.  Many buildings, both individual
residences and public housing units, especially those built
before 1950, contain lead-based paints on interior and exterior
walls, window sills, and other surfaces accessible to young
children.  In addition to paint, some plasters and putties have
also been found to contain high levels of lead.  Some older
primers have been found to contain from 30,000 to 600,000 mg
lead per kg of primer.  Soils adjacent to residences also have
been found to contain high levels of lead due to the leaching of
the lead as a result of the weathering of the painted surface.
For instance, in a study of lead contamination in urbana,
Illinois, lead was found in concentrations  up to 12,000 ppm in
soil.  Many other cities throughout 'the United States have similar
problems.

-------
                               -2-
     Numerous state and Federal agencies have been aware of
and concerned about the problem for some time and are pursuing
orogratns to identify lead poisoning and to remove lead-based
paint from residences.   The Lead-Based Paint Poisoning Preven-
tion Act, as amended, provides the Department of Housing and
Urban Development (HUD) with authority to eliminate the hazards
of lead-based paint poisoning in HUD-financed and other public
residential housing.  Unfortunately, the program has been hindered
by the lack of a determination of whether or'not lead-based
paint residues (paint chips, peelings, etc.) should be managed
and disposed of as a hazardous waste.

ISSUES

     Currently, the question of whether or not lead paint
wastes are hazardous is confused by Section 261.4 "Exclusions"
of 40 CFR Part 261, Identification and Listing of Hazardous
waste.  If these wastes are generated at a commercial facili y
and exceed the EP toxicity limit of 5 ppm for lead, then they
will be hazardous wastes.  However, when the paint residues
are generated at private and public residential units-, the
question arises as to whether the household waste exclusion
applies (See 40 CFR 261.4 (b)).  This provision excludes
household wastes from regulation as solid wastes, and therefore,
as hazardous wastes.  Household wastes are -defined as "any
material (including garbage) trash, and sanitary wastes (in
septic tanks) derived from households (including single and
multiple res idences, hotels and motels, bunkhouses, ranger
stations, crew quarters, campgrounds,  picnic grounds, and day
recreation areas.)"

     In the preamble to the Federal Register notice addressing
hazardous waste identification and listing (vol. 49, No. 220,
November 13, 1984, page 44998), EPA states that "there is no
basis for extending the household waste exclusion to waste
such as debris produced during building construction, renovation,
or demolition in houses or other residences, as EPA does not
consider wastes from these sources to be similiar to those
generated by a consumer in a home in the course of daily living."
Furthermore, in the preamble to the Final Hazardous Waste
Rules, Federal Register, Vol. 45, No.  98, May 19, 1980, EPA
noted that wastes generated by Federal agencies are not subject
to the household exemption since they cannot qualify as households,

-------
                              -3-
     Paint wastes are exempted from  regulation as a hazardous
waste if they are generated at individual households by the
houseowner doing his own removal.  On the other hand, if the
removal at an individual residence is done by a contractor,
the residues are solid wastes and must be evaluated with respect
to their hazardousness (EP Toxicity) and must be disposed of'
according to hazardous waste regulations if found to"be hazardous,

     In cases where paint residues are regulated under Sub-
title C, then commercial contractors who are performing the
renovation work and who generate less than 100 kg per month of
paint residues (which we believe is  likely), will be a condition-
ally exempt generator (Section 261.5) and their waste will not
be subject to regulation under Sections 262 through 266 of
RCRA.  we believe that only large renovation projects will
exceed the 100 kg per month limitations.

     While paint residues may not be regulated as hazardous
wastes, especially at private individual households or small
housing units, information should be made available tt> homeowners
warning them of the hazards associated with improper disposal
of paint residues.  Directions should be provided regarding
the proper disposal of these wastes.

     In the case of a larger commercial contractor whose activi-
ties result in the generation of more than 100 kg per month of
waste, for instance, at a public housing renovation project,
then the "hazardousness" of the waste must be determined.
In the case of lead-paint wastes, the EP Leachate Test should
be performed.  If the leachate lead  concentration exceeds 5
ppm, then the paint waste is a hazardous waste.  If the residues
are indeed hazardous, then the generator (removal contractor)
must comply with all appropriate regulations, (e.g., Parts 262
Standards ApplicabletoGenerators of HazardousWastes and
Part 263 Standards Applicable to Transporters of Hazardous
waste), and must send the waste to a facility that is permitted
or operating under RCRA interim status.

PROCESSES THAT MAY GENERATS HAZARDOUS WASTE

    There are several  methods available for removing lead-based
paints; however, the conventional lead paint removal techniques
currently available are  not totally effective and may exacerbate
the lead problem by dispersing  lead-containing particles
throughout the residence.  Newer, more effective abatement methods
which may be used for  lead removal include:

             * Peel Away - This consists of a caustic paste that
               is covered with  a plastic film (calcium, magnesium,
               and sodium hydroxide).  This paint removal
               system  can be used on wood, metal, stone and
               brick,  flat and  irregular surfaces.  It should
               be noted  that in a demonstration project conducted
               in Baltimore, waste water from the peel away
               process was found to have a lead content greater
               than 66 ppm, which was well in excess of the EP
               toxicity  limit of 5 ppm.

             * Off-Site  Dipping - Wood trim, ..oodwork, and doors
               are stripped of paint in enclosed chemical tanks
               containing methylene chloride.  When used for
               this purpose, spent methylene cnloride is a
               listed  hazardous waste.

             • Hi^h Efficiency  Particle Accumulator (HEPA) Sander -
               This is a power  disk sander that attaches to a
               HEPA vacuum to trap debris.  It is used on flat
               surfaces  only.  This method would generate a
               dust which could, depending upon the lead content,
               fail the  EP Toxicity Test.

             • Replacement - Removal and replacement of wood trim
               and old windows with new materials.  All of the
               painted wood products from the residence should
               be sampled and the EP performed on the wood
               samples.

     In any of the above methods, if the extractable lead
exceeds 5 ppm in the waste, then it is a hazardous waste.  If
the household waste exclusion does not apply then the wastes
must be handled and disposed of in accordance with the requirements
of 40 CFR Parts 262, 263, and 264, 265 and 270 as appropriate.

-------
                              -5-
CONTAHINATSD SOILS

     In addition to painted surfaces, the soils immediately
adjacent to residences may have high concentrations of lead,
due to the lead being leached from the exterior of the structure
as the paint weathers and ages.   For example, in a study of lead
concentration in Urbana, Illinois, concentrations of the lead
in the soil were found to range from 132 to 11,760 ppm adjacent
to and 240 to 6,640 ppm away from the houses.

     Whether or not "contaminated" soils are considered
hazardous wastes depends upon whether or not they are 1) removed
and transported off-site or left in place, and 2) exceed the  lead
toxicity limit of 5 ppm.

    If the contaminated soil is removed for off-site disposal,
it must be evaluated against the characteristics to determine
whether or not the soils are hazardous.  If the soils fail the
existing SP toxicity characteristic, then they must be taken
to a RCRA Subtitle C facility.   In the case of CERCLA sites
such soils must be taken to a RCRA facility which is in
compliance with CERCLA requirements for off-site disposal.
(See OSWER Directive number 9834.11 "Revised Procedures for
Planning and Implementing off-site Response Actions;
November 13, 1987.)

     The reouirements for on-site treatment of lead-contaminated
residential soils, which may seldom be practical, differs for
CERCLA and RCRA sites.  For CERCLA sites, such on-site treatment
can be performed without a permit being required.  However,
for on-site treatment at RCRA sites, a permit is required
unless treatment is performed in tanks or containers in compli-
ance with Section 262.34.  It should be noted that any on-site
treatment must consider the requirements of the individual
states in question, which may be more stringent that Federal
requirements.

     In the case of soil left on site, the property owner
will not normally be required to determine whether the soil is
a hazardous waste.  For soils that are left in place, EPA or
the appropriate state agency should set clean-up levels that
will ensure that the site will not pose a hazard when returned
to normal residential use.  I know that the CERCLA program often
makes such determinations.  For your information, described below
is the procedure OSW plans to provide in the RCRA Clean Closure
and RFl"Guidance Manuals for determining when contaminated
soils may safely be left in place and the site returned to
residential use.  We have had a.number of discussions with your
staff and we think that there is a general agreement on this
approach.

-------
                              -6-
     There are two approaches which should be used in making a
determination if further soil removal is required.  The first
is to look at health-based concentration limits in surface
soils; the second is an acid precipitation leach test (method
1312 in SW-846).

     The health-based limits should be used to determine how
much contaminated soil will have to be removed.  The RCRA Clean
Closure and RFI guidance Manuals provide direction on the appropri'
ate health-based levels to use.  Excavation would terminate at
the point where soil no longer exceeds the health-based concen-
tration limits.

     At that point, method 1312 should be run on soil samples
to determine the threat, if any, that might be posed by
remaining residual contaminants leaching into ground water.
For testing for lead, a pH of 4.2 should be used.  In the
absence of better numbers, the 5 ppm threshold used for the EP
should be the limit for method 1312 as well.  Since method 1312
is new,  no data on its use is available.  Once such data are
available, the ppm limit may be revised.

     The removed soil should be tested againsr. the EP after
removal to see if it fails the 5 ppm limit.  if so, it must be
sent to a Subtitle C facility.  If it does not fail, it can be
sent to a Subtitle D facility.

     If you have any questions pertaining to the above, please
do not hesitate to contact Jerry Coalgate of my staff.

Dear Mr. O'Brien:

    In response to your request of October 24, 1987 for an
updated copy of the Toxicity Characteristic Leaching Procedure
(TCLP) I have enclosed copies of the two Federal Registers where
it has appeared.

    The TCLP was actually created for two separate EPA rule-
makings.  The first rule, the Land Disposal Restrictions
Program, was finalized on November 7, 1986.  The TCLP was to be
used in this rule to determine if a waste could be land disposal
by testing it for solvents and dioxins.  The second rule, the
Toxicity Characteristic, was designed to determine if a waste is
hazardous based on its chemical toxicity.  This rule was
proposed on June 13, 1986 but has not yet been promulgated and
will not be finalized until late 1988.  At that time, it win
replace the current Extraction Procedure (EP) and wastes win
then have to be tested for not only the 14 EP constituents, but
for an additional 38 organic constituents as well.

    If you have any further questions about either of these
two rulemafcings, or the TCLP, please give me a call at  (202)
475-6722 or write me at the following address:

  Mr.  Phillip C. McGuire
  Associate Director, Law Enforcement
  Department of the Treasury
  Bureau of Alcohol, Tobacco and Firearms
  Washington, D.C.  20226

  Dear Mr. McGuire:

      Than* you for your October 14, 1987, letter regarding the
  disposal of explosive materials under the Resource Conservation
  and Recovery Act {RCRA).  We have reviewed the information you
  provided concerning the detonation of seized explosives that you
  believe would not fall under the RCRA Subtitle C program.  We
  think, however, that the seized explosives may indeed be a solid
  waste from the moment a decision is made that the explosives
  must be destroyed and not returned to the original owners.

      The basis for the Environmental Protection Agency's  (EPA)
  opinion is that the explosives are not being used for their
  originally-intended purpose  (e.g. , demolition of a building,
  military use, etc.), but rather are being detonated to discard
  the materials.  The explosives, therefore, would meet the
  definition of a solid waste as defined in 40 C£E Section
  261.2(a) and  (b).  If these explosives exhibit the
  characteristic of reactivity as defined in 40 CZS 261.23, they
  would be subject to the RCRA hazardous waste regulations for
  storage, treatment and disposal.  For example, detonation of
  reactive waste is considered a form of thermal treatment that is
  subject to Section 265.382, and shipments to the disposal site
  are subject to 40 CIS Parts 262 and 263.

      We recognize the Bureau of Alcohol, Tobacco and Firearms
  (BATF) has considerable experience in handling explosives.  Your
  internal procedures appear to be comparable to EPA's rules in
  many respects.  There are, however, some differences that may
  need to be examined.  For example, you state that the detonation
  areas must be at least 1,000 feet from buildings, woods, etc.
  EPA's regulations  (Section 265.382) require farther distances
  for quantities in excess of 100 Ibs.

-------
    I would like to suggest that EPA staff meet with your staff
to discuss how to reconcile the RCRA rules as they apply to BATF
detonation activities.  Rulemaking efforts may be required of
both agencies to resolve any inconsistencies.  In order to
schedule a meeting that will be mutually convenient, please
contact Mike Petruska, of my staff,  on 475-8551.  we believe
that this meeting will provide the opportunity to discuss
several points including what rulemakings may have to be
undertaken by either agency, and what exemptions may be
possible.

    If I can be of any further assistance-, please let me know.

                                       Sincerely,

                                              \i

 MEMORANDUM

 SUBJECT:  RCRA Status-of Surface  Impoundments at Rockwell

 FROM:     Marcia E. Williams, DirectorMit\C^^
           Office of Solid Waste         (

 TO:       Judy Kertcher, Acting Chief
           Solid Waste Branch  (5HS-13)
           Region V


     This memorandum is  in response  to your August 6,  1987  inquiry,
 and subsequent communications between France Norling  and the
 Characteristics Section staff,  regarding  the RCRA status of the
 surface impoundments at Rockwell  International's Ashtabula plant.
 Specifically, you requested assistance  in determining whether  the
 wastes managed in the  impoundments  exhibit the  hazardous waste
 characteristic of reactivity.

     As you are aware,  the reactivity characteristic promulgated  in
 the regulations is a narrative  definition.  In  particular, the
 regulations  define a sulfide  bearing waste as reactive when it is
 exposed to pH conditions between  2  and  12.5 and can generate toxic
 gases, vapors, or fumes in  a  quantity sufficient to present a
 danger to human health or the environment.  To  assist the  Regions
 and the regulated community in  interpreting this rule,  the Charac-
 terization and Assessment Division  provided interim guidance which
 indicated that wastes  releasing more than 500 mg H2S/Kg waste
 should be considered hazardous  (see enclosure), in addition to  the
 level, a testing method was also  provided.  We  are evaluating  the
 reactivity of the waste in  question based on this  interim  guid-
 ance.  However, you should  note that any final  decision as to  the
 hazardousness of the waste  (i.a.,. reactivity) must be based on the
 regulation.  See 40 CFR 261.23.

-------
    Based upon the analytical data provided by Region V,  the
average concentration of sulfide in all the lagoons is below our
guidance level of 500 mg/kg;  therefore, the wastes  are likely not
reactive under the hazardous  waste rules.   The upper bound of the
90% confidence limit, however, is above the guidance level for two
of the lagoons in question (lagoons 1 and 3).   This suggests that
the true concentration of the waste in the impoundments might be
above the guidance level. Therefore, before a definitive decision
can be made on the true concentration of sulfide in the sludge in
lagoons 1 and 3, additional sampling and analysis is recommended.
    Should you, or Rockwell, require assistance related to the
analytical methods or—sample handling procedures, please contact
                        ds Section at FTS 475-6722.   Questions

Dear Ms. Pace:

     This is in response to your letter of August 19, 1987, in
which you requested an interpretation of 40 CFR Section 261.31 as
it applies to the iron cake waste generated during the production
of methyldopa at a Merck and Company facility.  Based on the
information provided in your letter, the Agency has determined that
the iron filter cake generated during the production of methyldopa
does not meet the listing description of a spent solvent waste
(l..tef ,  EPA hazardous waste No. F005).  The basis for our decision
is discussed below.

     Our understanding of the process is that the iron cake is
generated when iron is filtered from the product; toluene is being
used for its solvent properties because it is acting as a carrier
for the product.  Next, the toluene is reclaimed for reuse in the
same process.

     With regard to the iron filter cake, the preamble and the
background document to the rule state that the Agency did not
intend to include within the scope of this regulation process
wastes that are contaminated with solvent  (see Hazardous Waste
Listing BD, p. 81 May 1980; letter from Steve Silverman to Michael
Rodbury, December 16, 1982).  The iron filter cake resulting from
the production of methyldopa at the Merck  facility is a process
residual that is contaminated with the toluene solvent.  The filter
cake, therefore, would not be EPA hazardous waste No. F005.

     Please advise your client of our interpretation and make them
aware that as a generator of this type waste, they are responsible
for determining whether the filter cake exhibits any RCRA  hazardous
characteristics fe.o. r corrosivity, toxicity, reactivity,  or
ignitability  [see 40 CFR 261.21-24]).  Also, you should investigate
whether this waste is regulated by the  state, which  may have more
           CTEBfT-*

-------
     Our determination is based on the information provided in
your letter and any deviations to the described process could
result in different interpretation.  If you wish to discuss this
matter in further detail, please call Yvonne Garbe at (202)
475-6679.

                                       Sincerely,

Dear Hs. Col*»t

     As mentioned in our telephone conversation of  December
16, 1987 regardina the difficulty of analyzing for  chlorinated
compounds in the leachate from your waste samples,  X would
suaoest that you do the following.

    Perform a total constituent analysis of  the waste itself
usinq SW-846 methods and assume that all of  the compounds
leach from the waste.  If the guidance  levels of  the compounds
are not exceeded assuming lOOt leaching, then no  further-
analysis or testing is required.  To determine 100% leachabllity,
the following calculation may be performed on the compounds
found in tho total analysis:

Dear Ms. Fort:

     This letter responds to your inquiry of November 23, 1987, requesting
a written statement clarifying the regulatory status of waste generated
by skimming off a toluene-containing paint product floating on water
which is the overspray trapped by a waterfall when wood pieces are
painted.  The waste has a flashpoint below 140°F.

     The spent solvent listings (i.e., EPA Hazardous Waste No. F001, F002,
F003, F004, and F005) cover wastes generated from  solvents which were
used for their "solvent" properties, namely, to solubilize or mobilize other
constituents, and which cannot be reused unless regenerated, reclaimed,
or otherwise reprocessed.  The listings do not cover manufacturing
process wastes contaminated with solvents that were used as reactants or
ingredients in the formulation of commercial chemical products. Hence,
waste solvent-based paints are not within the scope  of the F001-F005
spent solvent listings because  the solvents are ingredients in the paints.
Therefore, your ignitable  hazardous waste, having EPA Hazardous Waste
No. D001, is not subject to the requirements of the land disposal
restrictions final rule (51  FR 40572), November 7, 1986) which is
applicable to the spent solvent listings.

     If you have any further questions, you can call me at (202) 382-4770.

                                Sincerely,

Dear Dr. Wunderly:

    This letter is  in response to your letter of December 4, 1987,
requesting an interpretation of the regulatory status of your
liquid scintillation coclctail solution product, Ready Safe, under
the hazardous waste regulations.

    Under EPA's hazardous waste regulations, a waste is considered
to be hazardous if  it is listed specifically under 40 CFR Part 261,
subpart D, or if it exhibits a hazardous waste characteristic under
Part 261, Subpart C.  The four hazardous waste characteristics are
ignitability, corrosivity, reactivity, and extraction procedure
(EP) toxicity for certain metals and pesticides.  Section 261.33
contains a list of  products that become hazardous wastes when
discarded.

    Based on the information you provided, the product you describe
does not meet any of the listings under Part 261 Subpart D or to
exhibit any of the hazardous waste characteristics under Part 261
Subpart C.  Radioactivity is not presently included under the RCRA
hazardous waste characteristics or listing criteria.  Therefore,
your liquid scintillation cocXtail product when discarded  (or
intended for discard) does not appear to meet the definition of a
RCRA hazardous waste.

    Some State and local authorities, however, do regulate
radioactive materials as hazardous wastes.  Therefore, your
customers should contact their State and local authorities  for
further information on proper disposal of radioactive materials.

Charlotte, NC  28281

Dear Mr. Simpson:

    This letter is in response to your January 25 letter to
Marcia Williams regarding the regulatory status of asphalt
materials used at Associated Technologies, Incorporated.
Specifically, you requested a determination as to whether the
asphalt is a hazardous waste.

    If the asphalt were to be used as a commodity, e.g., for paving
roads, then it would not be regulated under the hazardous waste
regulations.  However, since the asphalt is disposed (buried in a
trench) it is a solid waste.  In the RCRA program, wastes are
defined as hazardous if they:  (1) are included on the  lists of
hazardous wastes contained in Subpart D of 40 CFR Part  261 or are
derived from, or are mixtures containing, such wastes;  or (2)
exhibit any of the hazardous waste characteristics described in
Subpart C of 40 CFR Part 261 (i.e. , ignitability, corrosivity,
reactivity, or extraction procedure (EP) toxicity).  The
descriptions and analytical data you provided for the asphalt
materials (AC-20 and Type I) indicates that they do not appear to
be hazardous wastes.

    However, the descriptions and analytical data you provided
appear to relate to the asphalt materials only, rather  than the
mixture of the asphalt materials and the concentrate from the film
evaporator.  Thus, if any of the wastes that contribute to the
concentrate are listed wastes, or  if the asphalt/concentrate
mixture exhibits any of the hazardous waste characteristics,
the mixture would be a hazardous waste.

-------
                                - 2 -
    Please note that  the interpretation is based upon the
information contained in your January 25 letter and reflects
current Federal regulations.   Since State and local regulations may
differ, you are encouraged to contact these authorities to ensure
that you are aware of all applicable regulations.  Should you have
any questions regarding this  interpretation, please contact David
Topping of the Waste  Characterization Branch at (202) 382-7737.

Dear Mr. Mirsky:

    This is in response to your  letter  to  Mr. Matthew  Straus
dated February 4, 1988, in which you request  an  interpretation
of the regulatory status of  Ecoscint A  and Ecoscint  O  under the
Federal ha2ardous waste rules.   My staff has  reviewed  the  data
on the two Ecoscint formulations that you  enclosed with your
letter dated February  4, 1988.   Neither Ecoscint A nor Ecoscint -
O is listed under 40 CFR 261.31, 261.32, or 261.33.

    However, a waste may still be hazardous if it exhibits one
or more of the characteristics of hazardous waste (i.e.,
ignitability, corrosivity, reactivity,  or  extraction procedure
(EP) toxicity) as described  in 40 CFR 261.21, 261.22,  261.23, or
261.24.  The data you  enclosed indicates that neither  product is
EP toxic and, based on their flashpoints,  neither product  is
ignitable.  There is,  however, insufficient data provided  to
make a determination on whether  the products  are corrosive or
reactive.  Therefore,  if you wish to dispose  of  these
formulations as non-hazardous wastes, you  must first determine
that they do not satisfy any of  the criteria  for corrosivity
(see section 261.22) or reactivity (see section  261.23).

    In addition, any State  in which you generate, transport,
treat, store, or dispose of  these formulations may have
regulations that are more stringent than the  Federal hazardous
waste rules,,.  You, therefore, should check with  the  state
agencies to^determine  what  regulations, if any,  apply  to
handling vajit£ Ecoscint A and Ecoscint  0.

Dear Mr. Boulden:

    This letter is  in  response  to your telephone conversation
with, and March 1,  1988  letter  to, David Topping of my staff.
Specifically, you have requested an interpretation as to the
applicability of certain hazardous waste definitions and
regulations.

    As you are aware,  wastes are considered hazardous if they
either (1) are listed  in the lists of hazardous wastes described
in Sections 261.31  through 261.33; or (2) exhibit any of the
characteristics of  a hazardous  waste described in Sections 261.21
through 261.24.  For purposes of clarity, it should be noted that
the wastes you describe  do not  meet the first criterion.  That
is, since the plant's  SIC code  is not 331 or 332, the wastes do
not meet the definition  of EPA  Hazardous Waste No.  K062, which
appears to be the only listing  that applies to pickling
operations.  Therefore,  the wastes would only be considered
hazardous  if they exhibit one of the characteristics or are mixed
with another waste  that  is listed.

         The responses to your  specific questions follow:

         1. Is the  spent pickle liquor a hazardous waste if
            it corrodes  1020 steel at a rate of >. 0.25
            inches/year?

            Yes.  This is the definition of a corrosive liquid
            waste as described  at Section 261.22(a)(2).

         2. Is the  sludge from  the bottom of the pickle tank a
            hazardous  waste if  its pH <. 2?

            Yes.  This is the definition of a corrosive aqueous
            waste as described  at section 261.22(a)(1).

-------
                               - 2 -
         3. Does paragraph 264.314 apply to the dewatered lime
            neutralized pickle sludge that is taken to the local
            landfill?

            No.  Part 264 applies to hazardous waste treatment,
            storage, and disposal units.   To the extent that the
            "local landfill" is not a hazardous waste facility,
            Section 264.314 is not applicable.

         4. In regards to the wastes discussed above, what if
            any, regulatory requirements does the EPA have?

            Since it is not clear whether the wastestreams of the
            Kentucky Plant do or do not exhibit the
            characteristics described above, a general answer to
            this question cannot be provided.  It is suggested
            that you direct this question to our Regional Office

Dear Wade:

    We have reviewed the data package submitted by Joseph
Stewart of Oak Ridge National Laboratory in support of his
petition to use the SOXTEC extraction system,  in place of the
conventional Soxhlet extraction system  (Method 3540), for
preparation of PCB samples for Method 8080 at  ORNL.  The PCB
data generated from split samples, run  concurrently, using the
conventional Soxhlet and the SOXTEC extraction techniques for
sample preparation, shows that these preparative techniques are
equivalent, within allowable standard deviation limits.  These
data also demonstrate that Method 8080, utilizing either
extraction technique, is appropriate for the analysis of PCB's
in soil and clay matrices at the low ppm level.  The SOXTEC
system actually proved to be the superior technique when time
constraints were considered, taking only 2 hours for sample
preparation vs. 17 hours for Soxhlet.

    From the submitted information, we  believe that ORNL has
demonstrated the equivalency of the Soxhlet and SOXTEC
extraction procedures for generating PCB data, and their
petition to use the SOXTEC extraction system for preparation of
PCB samples in place of the Soxhlet method  (Method 3540) should
be granted. 'Furthermore, we in the RCRA program, with support
•from Superfund, are in the process of using this ORNL data to
develop a general extraction procedure  for SW-846 using the
SOXTEC apparatus.

-------
                               -2-

    We are in process of assembling samples to be split for a
multilaboratory validation study of the SOXTEC extraction
procedure for PCB's.  This will be followed by a program to
expand the utility of this technique into a general SW-846
method with a scope equivalent to that of Method 3540.

    If we can be of any further assistance to you, please call
Barry Lesnik at FTS 382-4761.

                                Sincerely yours,

     Our section has recently received several inquiries
regarding whether Class C explosives intended for disposal
are classified as Subtitle C hazardous wastes,  since it is
apparent that confusion exists, I would like to clarify this
issue.

     To date, only those Class C explosives identified as
off-specification small arms ball ammunition up to and
including 0.50 caliber have been demonstrated not; to be
subject to the Subtitle C hazardous waste  requirements.  The
Office of Solid Waste concluded that these materials are not
"reactive" within the meaning of 40 CFR 26l.23(a}(6) based
on information provided by Remington Arms  Company and the
Army  (see attached memorandum) .  Furthermore, in a letter
from Marcia Williams to J. Carricato of DOD  (also attached)
it was emphazised that the OSW determination only applied to
the ball ammunitions since other ammunition types of similar
caliber may be subject to RCRA.  For the remaining Class C
explosive wastes, as for any other solid waste not listed in
40 CFR 261 Subpart D, the generator must determine whether
his particular waste exhibits the reactivity or other
characteristics identified in 40 CFR 261 Subpart C.

     We will be working with the Army on the Class C

          Office of Solid Waste (OS-300)

TO:       William E. Muno, Acting Associate Director
          Waste Management Division  (5HS-13)

    I am responding to your request  for clarification of the
phrase "under standard temperature and pressure" as used in the
ignitability characteristic  (40 CFR  261.21).  The phrase refers
to the conditions used to determine  whether the waste is a
liquid or a solid.  Wastes are evaluated at standard temperature
(20 C/68 F) and pressure  (1 atxn) and, if not a liquid und<>.r
these conditions are not subject to  the flash point criteria
of 261.21(a)(1).

    Based on the information in your memorandum, Chevron's
polystyrene production distillation  still bottom tar wou3d.
not be a liquid within the meaning of the ignitability
characteristic and therefore only evaluated against the
criteria of 261.21(a)(2).

    In response to your  inquiry about the Office of Solid
Waste's use of the LD50, these values are used as one of the
criteria for listing hazardous wastes.  Specifically, it is used
to designate any Acutely Hazardous Waste.  The LD50 value is
used unchanged, i.e. there is no extrapolation to humans.

         "...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...(Waste listed in
         accordance with these criteria will be
         designated Acute Hazardous  Waste)."

SUBJECT: Definition of Reactive Waste - Explosivity

FROM:    David Friedman, Chief
         Methods Section, (OS-331)

TO:      Sonya Stelmack,
         Assistance Branch,  (OS-343)


    As you requested,  I have reviewed the testing protocols and
classification criteria used by the Department of Defense  in
evaluating the explosivity of material (Army TB 700-2, Navy
NAVSEAINST 8020.8, Air Force TO 11A-1-47, DLA DLAR 8220.1).

    It is my judgement that the only materials that would
exhibit the reactivity characteristic (40 CFR 261.23), due to
their potential explosivity, are those that fall into
Department of Defense Hazard Classes 1.1, 1.2, and 1.3.
Materials rated as Class 1.4 would, therefore, not be an
explosive within the meaning of the reactivity characteristic.

SUBJECT: Regulatory status of Solvent-Contaminated Wastestreams
         from a Pharmaceutical Manufacturer

FROM:    Devereaux Barnes, Director
         Characterization and Assessment Division (OS-330)

TO:      Arthur Moretta, UIC Control Program
         Water Division, Region V  (5WD-TUB-9)


    This T\emorandum is in response to your request for
determination of tlie regulatory status of aquaous wastestreams
generated at an Upjohn Company pharmaceutical facility in
Kalamazoo, MI.  All answers are based on our best understanding
of the process flowsheets which you sent and the information
which you provided over the telephone to my staff.

    The spent solvent listings cover those streams that are
used to solubilize or mobilize other constituents (e.g.. for
degreasing or fabric scouring, as diluents, extractants,
reaction and synthesis media, and similar uses) and through
such use, have become contaminated to the extent that they must
be reclaimed prior to further use or reuse.,  see 50 EB 53315,
December 31, 1985.

    Use as a reactant or an ingredient in the manufacture or
formulation of a commercial chemical product is not classified
as a solvent use for the purpose of the RCRA hazardous waste
listings F001 - F005.  Therefore,  spent materials from these
11 non-solvent" uses do not meet the listing descriptions  for
spent solvents.  Also, process wastes that become contaminated
with small amounts of solvents during processing are not  within
the scope of the spent solvent listings.  An example of  this  is
an aqueous effluent from a  liquid-liquid extraction step,  in
which a solvent has been used to extract a product from  the
water and the water becomes contaminated with small amounts of
solvent.  In this example,  the solvent is removed with the
product and the sol vent-contaminated water  is not a spent
oolvcnfc.	

-------
                               -2-
    Based on our review of the data submitted,  we  have  made  the
following determinations:

o   All streams being sent to disposal  wells  from  the acetone,
    methanol, and methylene chloride recovery processes (pp.  A,
    B, C, and D) either meet the listing  description for spent
    solvents or are residuals derived from the treatment of
    spent solvents and therefore should be designated as an  EPA
    hazardous waste (F001  - F005).

o   Those aqueous streams  which result  from liquid-liquid
    extraction steps involving solvents are considered  process
    wastestreams and as such, do not meet the listing
    description for spent  solvent streams (see above).

o   Filter press effluents such as the  one exiting the  unit
    designated "ST-110" (p. 2-1) are considered spent solvent
    streams because they consist of a solvent that was  used as
    a carrier for the product in the filtration step.  However,
    filter press effluents, such as the one exiting the filter
    designated "VF-" (p. 4-2) are process wastewater streams,
    not spent solvent streams, because  water was introduced
    into the production process as the  carrier for the  product
    in filtration.  In this configuration, the solvent  was
    removed prior to filtration; the small quantity of  solvent
    remaining in the system does not render the wastewater
    filter press effluent  a spent solvent.

o   Rinse wastewaters, such as those from product or equipment
    rinsing steps (pp. 1-3, 2-1) are not  considered spent
    solvents because they  are process streams which may have
    become contaminated with organic solvents.

    Although a particular  waste stream may not meet the  listing
description for spent solvents, it may be hazardous  if exhibits
one or more of the hazardous characteristics described  in
40 CFR 261.20-261.24.  Certain states may also have  special
restrictions on tne disposal of solvent-contaminated
wastestreaas.

    Thank you for your inquiry.  If you have any  further
questions, please contact Ron Josephson at FTS 475-6715.

Dear Ms. Heyob:

    This letter will clarify our telephone conversation, and
your follow up letter, with respect to use of total
concentration to demonstrate that a waste does not exhibit the
characteristic of Extraction Procedure Toxicity.


    The evaluation to be performed is as follows:

    l.  Determine the concentration of the analyte of concern  in
       the waste expressed in g/lOOg (A).

    2.  Determine the waste's percent liquid (B) .

    3.  Calculate the maximum theoretical extract concentration,
       in mg/L, (MTEC) using the formula.

         MTEC - 	(AJ	
                [B +  (20)(100-B)]

    4.  If MTEC is below the Extraction Procedure Toxicity
characteristic regulatory level, then the waste does not
exhibit the characteristic.  If MTEC is above the regulatory
level,  then one would have to run the test to show that the
waste is non-hazardous.

                                    Sincerely yours,

Dear Mr. Stockli:

     This is in response to your letter of March 27, 1989, in
which you asked about the regulatory status of waste solvent-
based glue.  Specifically, you wished to know whether or not the
F-listings (40 CFR 261.31) apply to characterization of waste
dried or non-solidified glue.

     The spent solvent waste codes (F001 - F005) apply only to *
solvents that are used for their solvent properties.  See      £
50 FR 53316 (December 31, 1985).  These listings do not apply ta|
solvent-containing products that may become wastes if the
solvents are ingredients, such as for paint or glue.  However,
the waste glue could meet one of the hazardous waste
characteristics, especially if it is in the non-solidified form.
(See 40 CFR 261.20 - 261.24.)  The generator is responsible for
ascertaining whether the waste exhibits one or more of thes^
hazardous characteristics.  In addition, the generator should
review state regulations, which may be more stringent than
Federal regulations.

     Thank you for your inquiry.  If you have any further

Dear Ms. Schupak:

    This letter is in response  to your  March 7,  1989,  letter
regarding the proposed Maximum  Contaminant Level Goal (MCLG)  for
barium in drinking water.   In addition  to  your support for the
proposed MCLG, you suggested that the EP Toxicity level for
barium (Table 1 in 40 CFR  261.24)  be revised immediately upon
any change to the MCL.

    The EP Toxicity levels are  based upon  the constituents'
expected fate and transport as  well as  their MCLs.   Currently,
the estimated fate and transport  processes are represented by a
factor of 100.  That is, the EP Toxicity levels are equal  to  100
times the MCLs.  The Agency is  currently re-evaluating the fate
and transport of the EP constituents to determine whether  the
100 factor is an appropriate estimate of these processes.   Since
this factor may change, it is not presently clear whether  a
change in the regulatory level  (which depends upon both this
factor and the MCL) would  be appropriate.   Therefore, needed
changes to the EP regulatory levels (resulting from changes in
either or both of these values) will be evaluated on a
case-by-case basis and any warranted changes to the regulatory
levels will be proposed as modifications to 40 CFR 261.24.

    Should you have any further questions  on this issue, feel
free to contact Reva Rubenstein,  Chief  of  the Characteristics

Honorable Lloyd M. Bentsen
United States Senator

Austin, Texas  78701

Dear Senator Bentsen:

    Thank you for your April 24, 1989, letter regarding
Hoi1is E. Ervin's concerns about the March 14, 1989, court
opinion supporting the Environmental Protection Agency's (EPA)
interpretation of the regulatory status of contaminated
environmental media  (such as soil and ground water).

    EPA believes that a hazardous waste does not necessarily
lose its hazardous characteristic when it is combined with an
environmental medium, and that, unless demonstrated otherwise,
the contaminated medium should be managed as a hazardous waste
because it contains t hazardous wastfc.  (The environmental
medium itself is not & hazardous waste.)  To consider
contaminated media as uewly generated wastes for purposes of
determining whether they are hazardous could be an  incentive
for the purposeful contamination of environmental media with
hazardous waste in an effort to avoid regulations otherwise
applicable.

    EPA has established a process under which persons
may petition the Agency to have their waste removed from
regulatory control on a case-by-case basis (sometimes called
"delisting").  Under this process, EPA evaluates the waste in
question and determines whether it needs to be regulated as a
hazardous waste.  In addition,  EPA is currently examining ways
to streamline this process - e.g., setting deminimis levels of
contaminants which, when met, would allow for the management of
wastes outside the structure of the hazardous waste
regulations,

    As found by the D.C. Court of Appeals, the "contained in"
rule has been a consistent and reasonable interpretation since
the promulgation of the applicable regulations in  1980.  To
change an established regulatory  interpretation, the Agency is
required to provide notice and an opportunity for public
comment  (i.e., regulatory interpretations cannot be changed at
the "whim" of EPA).

Dear Ms. Belden:

     This is in response to your letter of May 12, 1989 to Joshua
Sarnoff of the Office of General Counsel.  You requested that EPA
clarify an April 1987 Hotline report on 1,1,1-trichloroethane
(TCA) contained in a sand-metal-solvent mixture, created froai
degreasing metal parts in TCA, grinding the parts, and filtering
the cooling fluids.  EPA continues to believe that this waste
stream does not meet the F001 listing description.

     The sand-metal-solvent mixture is a process waste stream
contaminated with solvent, not a spent solvent waste or ?• mixture
of wastes with spent solvents.  The Agency clarified the scope of
the spent solvent listings on December 31, 1985 (50 F_B 5^5'.6),
and clearly indicated that listed spent solvent wastes do not
include such process wastes.  Further, unless these process
wastes are characteristically hazardous (see 40 CFR 26.1.20 -
261.24), the waste minimization certification of SCR& section
3002(b) does not apply.  Please be aware that states may have
more stringent hazardous waste regulations.

     Thank you for your inquiry.  If you have any further
questions, please contact the RCRA/Superfund Hotline at
(800)424-9346.


                                        Sincerely,

          Region V

    This memorandum responds to your May 30, 1989,  request for
clarification concerning RCKA authorities to regulate  dredged
sediments that exhibit one of more characteristics  of  a
hazardous vaste.  As you stated, EPA's policy  regarding such
materials is defined in the January 23, 1986,  memorandum from
Marcia Williams to David Stringham.  However,  the U.S.  Army
Corps of Engineers (USACOE) published a Federal Register
notice on April 26, 1988 (53 FR 14902), in which USACOE
concluded that dredged materials are not solid waste and,
therefore, not subject to RCRA.  These contradictory statutory
interpretations and policies .have caused confusion  in  properly
implementing RCRA authorities over dredged sediments.

    The Agency's policy regarding the applicability of RCRA to
dredged sediments remains unchanged from the January 23,  1986,
memorandum.  The pertinent points of this policy are:   1) point
source discharges subject to Section 402 of the Clean  Water Act
(CWA) are exempt from RCRA, 2) hazardous wastes dumped into
surface water in a manner that does not trigger Section 402 of
the CWA are subject to RCRA regulation, as well as  any sediments
that are contaminated by such discharges  (under the contained-in
rule), and 3) in cases where the pollutants discharged into
surface water are not subject to RCRA, sediments would be
regulated under Subtitle C of RCRA only when they are  dredged
from the surface waters and only if they exhibit one or more
characteristics of hazardous wastes.

    The Office of Solid Waste and the Office of General Counsel
are currently evaluating the best approach to  take  in  addressing
USACOE's April 26, 1988, Federal Register notice.   I agree
that a definitive statement of RCRA authorities over dredge
sediments is needed to clarify the regulatory  requirements.

    Thank you for bringing this issue to our attention.  Should
you have any questions, your staff should contact Mitch Kidwell,
of my staff, at FTS 475-8551.

      Dear Mr.  Wagner:

            I am writing in response to your letter requesting written
      clarification of the Resource Conservation and Recovery Act
       (RCRA)  definition of a liquid as it applies to ignitable and
      corrosive wastes.

            There are three RCRA definitions which include  the term
      "liquid".  The definitions vary depending on the  specific
      regulatory application.  For hazardous waste identification by
      means of  the three relevant characteristics (Ignitability,
      Corrosivity or Extraction Procedure Toxicity), the general  term
      liquid applies.  "Liquid" is defined as the material (liquid
      phase)  that is expressed from the waste in Step 2 of Method 1310
       (the Extraction Procedure).

            As Mr. Friedman indicated, only those wastes that contain a
      liquid component are subject to testing against the  flash point
      criteria  of Section 261.21.  Therefore, if a waste does not yield
      a  liquid  phase when subjected to Method 1310, it  cannot be  an
      ignitable waste under the criteria of Section 261.21(a)(1).

            Similarly, Section 261.22(a)(2) states that  a liquid waste
      is a corrosive waste if it exhibits a pH less than or equal to 2
      or greater than or equal to 12.5.  If a waste does not yield a
      liquid when subjected to Method 1310, it is not evaluated against
      this criteria and is not a corrosive waste.

            A second definition of liquids which is applied to determine
      whether a drummed waste is prohibited from land disposal because
      it contains "free liquid", is found in Method 9095 (the Paint
      Filter Test).   If any material drips from the filter during the
      test,  the waste is deemed to contain "free liquid" and is banned
      from land disposal.

-------
     Many people have used the Paint Filter Test to evaluate
wastes for ignitability or corrosivity.  This is done to save
time and effort.  Since liquids that separate out of the waste
using Method 9095 are generally also liquids using Method 1310
wastes that contain ignitable or corrosive liquids using Method
9095 can generally be considered to be ignitable or corrosive
wastes.

     The third definition of liquids was developed when the 1984
amendments to RCRA prohibited the use of adsorbents to solidify
liquid wastes if the adsorbents would release the contained
liquids under landfill pressures.  Prohibited adsorbents are
those that contain "releasable liquids". While the Agency has not
yet promulgated a specific test procedure for defining when a
waste contains "releasable liquid", a draft procedure has been
developed and proposed - Method 9096 (the Liquid Release Test).

     I trust that this explanation clarifies the RCRA
definitions.  Please contact us if you need further assistance.

                                          goes on to state that this removal is beneficial
                                          to human health and the environment since it
                                          would eliminate potential sources of
                                          groundwater contamination. (55 ER 39410)

                                              Should the generator choose to remove the
                                          hazardous waste from the unit on a one-time

CC Johnson & Malhotra,  P.C.
Suite 215

Lakewood, CO 80228

Dear Mr. Berning:

     I am writing in response to your letter requesting
clarification regarding when it is necessary to digest EP (Method
1310) and TCLP (Method  1311)  extracts prior to metals analysis.

     The Extraction Procedure Toxicity Characteristic (40 CFR
261.24)  states that a waste  is a hazardous waste if the extract
of the waste contains any of the listed constituents above the
indicated regulatory levels.   Method 1310 and 1311 extracts
should be digested prior to  metals analysis for several reasons.
The two most important  ones  being:

     1)    Extracts often consist of a mixture of phases. Unless
          the extract is digested prior to the determinative step
          all of the metallic species may not be in a form which
          gives an accurate  detector response (e.g., TCP or AA).

     2)    During cold storage of Method 1310 extracts, it has
          been reported that precipitation sometimes occurs.
          Unless the extracts are digested prior to the
          determinative step, any metal that precipitates would
          not be counted and this would lead to an
          underestimation of extract concentration and a
          potentially incorrect hazard classification.

-------
                               -2-

     The Resource Conservation and Recovery Act (RCRA)
regulations hold the regulated individual responsible for
accurately characterizing the properties of the wastes.  Some
wastes may yield extracts which do not require digestion to yield
accurate concentration results.  However, persons who analyze
Method 1310 or 1311 extracts without prior digestion of the
extracts, and who therefore incorrectly characterize their waste
would be deemed not to have made a good faith effort to
characterize their waste.  In fact, Step 8.14 of Method 1311 (40
CFR 268,  Appendix I) specifically states that, "TCLP extracts to
be analyzed for metals, other than mercury, shall be acid
digested."

     I hope that the above answers your questions.

                                 Sincerely,
                                 David Friedman

Dear Mr. Poirier:

     I am writing in response to your letter of December 1,  1989
regarding the ignitability characteristic.

     The Office of Solid Waste (OSW)  currently has two test
protocols for determining the ignitability of a liquid - the
Pensky-Martens Closed Cup (SW-846 Method 1010)  and the Setaflash
Closed Cup (SW-846 Method 1020).  These methods are for liquids
only and do not establish that a solid possesses the ignitable
characteristic.  For solids,  there is only a narrative definition
set forth in the regulation itself:

          "It is not a liquid and is capable, under standard
          temperature and pressure, of causing fire through
          friction, absorption of moisture or spontaneous
          chemical changes and when ignited, burns so vigorously
          and persistently that it creates a hazard."

     The OSW has been conducting work to develop test methods for
ignitable solids.  A method has been developed but has not been
evaluated and no decision has been made on the appropriate
regulatory thresholds.  Presently, other priorities have resulted
in the work being put on hold.

     If you .have any further questions, please contact Gail
Hansen of my staff at (202) 475-6722.

                                    Sincerely yours,

 Dear Ms.  Senegal,

      I  am writing in response to your letter of June 28,
 1991 requesting clarification on the determination of the
 ignitability characteristic.   The  characteristic,  as
 defined in  40 CFR §261.21, is  applicable to  both  solid
 and liquid  wastes;  however, test methods are currently
 not available for  solid  waste.  Because standardized,
 approved  methods are not  available, the  characteristic
 determination for  solids  (e.g.,  determining  whether
 solids  will cause vigorous and persistent fires through
 friction, absorption of moisture, or spontaneous chemical
 changes,  as listed in the  regulations) has to depend upon
 knowledge  of  the  waste   stream,  as  noted  in  40  CFR
-S201.1(a)(2)(ii)  and §262.11(c)(2).   Waste analyses of
 solid materials may be helpful for determining if any of
 the  detectable  compounds  are  known  to  be  ignitable.
 Please  note that meeting any (not all)  of the  properties
 specified in the definition of ignitability qualifies a
 waste as  characteristically ignitable.

      There  are no specific definitions of "liquid" (i.e. .
 5%,  10%)  in the ASTM method D-93 (Standard Test Method
 for Flash Point by Pensky-Martens Closed Tester) but the
 types of  materials  that may be tested are  specified in
 the method  as  "fuel  oils, lube oils,  suspensions  of

        Dear Mr. Licht:

             I am writing in response to your letter of February  13,  1992
        to Sylvia Lowrance concerning clarification of the  corrosivity
        characteristic as it applies to solids.

             The current characteristic defines a corrosive waste as  a
        solid waste that: a) is aqueous and has a pH less than  or equal
        to 2  or greater than or equal to 12.5  b) or is a liquid  and
        corrodes steel at a rate greater than 6.35 mm per year.    We  have
        two methods in SW-846 for measuring the corrosivity of  these
        liquids.  One method is for aqueous liquids (Method 9040,  pH
        electrometric measurement) and the other method is  for  non-
        aqueous liquids (Method 1110, corrosivity of steel).

             We realize that the existing corrosivity characteristic  has
        two problems:  1) it applies only to liquid wastes,  thus
        corrosive solids such as lye, solid acids, or in your case,
        baghouse dusts, are not covered and 2) the term "aqueous"  (as in
        aqueous liquid) has not yet been defined, thus, there is  a chance
        that some users of our method for pH determination  will
        incorrectly apply the method to certain non-aqueous wastes.

             With respect to solids, the Office of Solid Waste  has
        developed a method that appears to be suitable for  determining
        their corrosivity.  This method, Method 9045 - Soil and Waste pH
        (copy attached), mixes a waste sample with water in a 1:1  ratio
        and determines the pH of the solution with a pH meter.  Method
        9045 will be included in the proposal for the second update to
        the third edition of SW-846, "Test Methods for Evaluating  Solid
        Waste, Physical/Chemical Methods."   We anticipate  the proposal
        appearing in the Federal Register sometime this spring, with
        promulgation sometime in 1993.

     Promulgation of Method 9045 would not by itself expand the
scope of the corrosivity characteristic.  This requires that the
Environmental Protection Agency (EPA) draft regulatory language
to include corrosive solids and to employ Method 9045 for their
determination.  We are not sure at this time when that will
happen.  In the interim, we recommend the use of Method 9045 for
the determination of corrosive solids.

                                          JULY  1992
3.  Alcohol-Content Exclusion for the
    IgnltabiHty Characteristic

    A generator produces a wastestream with a
flash point of 54 degrees Celsius that contains
the following three components:  water (77
percent), alcohol (13 percent), and a non-
alcoholic liquid component (10 percent).
According to the  "alcohol exclusion" in 40
CFR §26121(a)(l), the characteristic of
ignitability will not apply to an aqueous
solution that contains less than 24 percent
alcohol and which has a flash point less than
60 degrees Celsius.  Does the presence of a
non-alcoholic component cause the aqueous
solution to be regulated as an ignitable waste
(D001)?

    No, the additional non-alcoholic liquid
  omponcnt will not cause the wastestream to
 DC regulated-as a D001 waste. Despite the
presence of the non-alcoholic liquid
component,  the wastestream continues to
qualify for the alcohol exclusion in 40 CFR
 §261.21(a)(l). According to the May 19, 1980,
Federal Register (45 ER, 33108), EPA
originally intended for the alcohol exclusion to
exempt alcoholic beverages and some types of
 latex paints, which exhibit low flash points due
 to the alcohol content, but do not sustain
 combustion because of the high water content
 The alcohol exclusion in 40 CFR
 §261.21(a)(l), however, is not limited to those
 wastes mentioned in the May 19, 1980, FjsdsraL
 Register. It applies to all aqueous solutions
 containing less than 24 percent alcohol, even if
 additional non-alcoholic components are
 present EPA clarified  in the June 1, 1990,
                (55 ER 22543) that the term
 "alcohol" in §261.21(aXl) refers to any alcohol
 or combination of alcohols. The Agency notes,
 however, that if the alcohol is one of those
 aJcohols specified in EPA hazardous waste
 codes F001-F005 and has been used for its
 solvent properties, the waste must be evaluated
to determine if it should be classified as an F-
listed spent solvent waste.

   The alcohol exclusion for the ignitability
characteristic was adopted from the
Department of Transportation's (DOT) defini-
tion of "combustible liquids" in 49 CFR
§173.115(b). The alcohol exclusion in 49 CFR
§ 173.115(b)(2)(ii) applies to aqueous solutions
containing 24 percent or less alcohol by
volume which contain no less than 50 percent
water.  Since EPA originally intended to be
consistent with DOT regulations when promul-
gating the alcohol exclusion in §261.21(a)(l),
the 50 percent water stipulation may be applied
to the ignitability characteristic. Therefore, as
clarified in an internal EPA memorandum, for
the purpose of the ignitability characteristic in
§261.21(a)(l), "aqueous" means a solution
containing at least 50 percent water by weight

Mr. Larry F. Runyan
American Furniture Manufacturers Association
223 South Wrenn Street
P. O. Box HP-7
High Point, NC 27261

Dear Mr. Runyan:

     I am writing in response to your  letter  of July 1,  1992 to
Mr, William K. Reilly, Administrator of  the Environmental
Protection Agency in which you petition  EPA to accept ASTM D4982-
89 (Method B) as an equivalent method  of testing for the
ignitability of solid waste.

     In order to determine whether a method is equivalent to one
in  SW-846, the SW-846 method it is intended  to be equivalent to
must already be promulgated and be required for use in a
regulation.  In your case, a method for  the ignitability of solid
waste has not yet been promulgated.  Therefore,  equivalency
cannot be demonstrated.

     The Office of Solid Waste is currently developing a test to
determine the ignitability of solids.  Our procedure is  based on
the Department of Transportation burn  rate test.   As we  do not
have a promulgated method to test for  the ignitability of solids
at present, we recommend ASTM D4982-89 (Method A)  as interim
guidance.  This ASTM method is a good  qualitative test of
ignitability, but is not quantitative  enough  to be considered for
a SW-846 promulgated method.  It only  addresses ignition and does
not provide any quantitative measurement of how vigorously the
material burns.  We do not recommend ASTM D4982-89 (Method B)  as
it only tests the vapors above the sample and not the solid
sample itself.

     We do not require generators to test or  to specifically use
the methods listed in SW-846, except under the five circumstances
listed in the following sections of 40 CFR:
                                                           Printed on Recycled Paper

     (1)  260.22(d)(1)(i) - Submission of data in support of
     petitions to exclude a waste product at a particular
     facility (delisting petitions).

     (2)  261.22(a) - Evaluation of wastes against the Corrosivity
     Characteristic  (corrosivity).

     (3)  261.24(a) - Evaluation of wastes against the Toxicity
     Characteristic  (mobility of toxic species).

     (4)  264.314(c) and 265.314(d) - Evaluation of wastes to
     determine if free liquid is a component of the waste (free
     liquid).

     (5)  270.62(b)(2)(i)(C) - Analysis of wastes prior to
     conducting a trial burn in support of an application for a
     hazardous waste incineration permit (incinerator permit).

     SW-846 methods are only intended to serve as a guidance for
the regulated community.  If the generator can demonstrate that
his/her method has documented QC and is sensitive enough to meet
the regulatory limits, then the generator may use that method in
place of an SW-846 method.

     I hope that this information will be of use to your
analytical program.  If you have any questions, please feel free
to call me at (202) 260-4778.

                                     SEPTEMBER 1992
 2. "Aqueous" as Applied to the
    Corrosivity Characteristic

    According to 40 CFR §26122, a solid
 waste exhibits the characteristic of corrosivity
 if it has either of the following properties:

 •   It is aqueouj and has a pH less than or
    equal to 2.0 or greater than or equal to
    12J(§26122(aXl))

 •   It is a liquid, which corrodes steel at a rate
    greater than 635 mm (0250 inch) per
    year (§26122(a)(2)).

 Mary aqueous wastes are liquids. Must
 aqueous liquid wastes be evaluated
for bothpH and rate of steel corrosion?

    While nonaqucous  liquids need only be
 tested using the steel corrosion test, aqueous
 liquids must be evaluated for both pH and rate
 of steel corrosion. If an aqueous liquid has a
 pH less than or equal to 2.0 or greater than or
 equal to 12.5, d corrodes steel at a rate greater
 than 6.35 mm per year, it is regulated as a
 corrosive waste (D002).  Therefore even if an
 aqueous liquid passes the §261.22(a)(l) pH
 test (pH greater than 2.0 and less than 12.5),  if
 it corrodes steel at a rate greater than 6.35 mm
 per year, it exhibits the characteristic of
 corrosivity.

    According to the background document for
 this characteristic, Corrosivity Characteristic:
 IdenrificatJon and Listing of Hazardous Waste
 Under RCRA Subtitle C. Section 3001. an
 aqueous waste with a pH between 2.0 and 12.5
 may, under certain conditions, corrode steel at
a rate greater than 6.35 mm per year.  Several
factors influence the rate of metal corrosion.
In addition to pH, other important factors
include temperature, metal(s) involved, and
aeration and composition of the corrosive
medium. The background document indicates
that although alkaline solutions, in practice, do
not severely damage steel,"... a corrosive
material with a pH less than 4.0 will cause iron
to dissolve rapidly." In other words, although
an aqueous waste in liquid form that has a pH
between 2.0 and 4.0 (i.e., an acidic solution)
passes the pH test, the v aste may nonetheless
fail the steel corrosion test and be regulated as
a corrosive (D002) hazardous waste.

   Although there is no regulatory definition
of the term "aqueous," for purposes of the
corrosivity characteristic an aqueous waste is
defined as a waste for which pH is measurable.
Since not all liquid wastes are in a form
amenable to pH measurement, this operational
definition of aqueous implies that the presence
or absence of measurable dissociated hydrogen
ions divides the universe of liquid wastes into
two mutually exclusive categories:  aqueous
and nonaqueous.  While all liquid wastes must
be evaluated for rate of steel corrosion, those
liquid wastes classified as aqueous are subject
to both the pH and steel corrosion tests. The
background document explains that those who
generate or manage a waste can best determine
whether it is in a form suitable for pH
measurement, and therefore an aqueous waste
requiring the pH test.

RCRA/SUPERFUND/OUST HOTLINE MONTHLY  REPORT  QUESTION
                        SEPTEMBER 1992
                          (CONTINUED)
                  This working definition of aqueous means
               that aqueous wastes can be in nonliquid form.
               Suspensions, sols, or gels for which pH is
               measurable are examples of aqueous
               nonliquids. The background document for the
               corrosivity characteristic states that, during a
               pH determination, the form of the waste should
               be taken into account As nonaqucous liquids
               are subject to the steel corrosion test only,
               aqueous nonliquids only require evaluation for
               pH. Therefore, by definition, an aqueous
               nonliquid with a pH greater than 2.0 and less
               than 12.5 cannot be regulated as D002, since
               §261.22(a)(2) applies only to liquids that
               corrode steel.

                  The operational definition of aqueous for
               the characteristic of corrosivity differs from the
               meaning of aqueous as the term applies to the
               ignitability characteristic. Under §261.21(a)(l),
               aqueous solutions containing less than 24
               percent alcohol by volume are excluded from
               regulation as ignitable liquids.  In an internal
               Agency memorandum clarifying this exclusion,
               an aqueous solution is defined as a solution
               which contains at least 50 percent water by
               weight  Applying this 50 percent water
               stipulation to define "aqueous" in the context of
               §261.22(a)(l) is inappropriate. Instead, for
               purposes of the corrosivity characteristic,
               aqueous means in a form amenable to pH
               measurement

                 Oegreasing

                 According to 40 CFR §26131, chlorinated
              fluorocarbons (CFCs) used in degreasing are
              classified as FOOL EPA included CFCs used
              in degreasing in the F001 listing because of
              concern for their potential contribution to the
              depletion of stratospheric ozone. Are
              hydrochlorofluorocarbons (HCFCs) used in
              degreasing also regulated as F001 ?

                 Because the F001 listing description
              includes all chlorinated fluorocarbons,
              hydrochlorofluorocarbons used in degreasing
              operations are also classified as FOOL Of
              course, the solvent formulation must meet the
              10 percent (by volume) beforc-use criterion in
              the F001 listing. Hydrogenated fluorocarbons

Dear Sirs,

I have received your letter of 22 December 1992, requesting additional information on three hazardous waste
testing issues, and am pleased to be of service.  In your first question, you noted that some people believe •
that atmospheric oxidation of Cr(IH)  to Cr(VI) in a landfill containment may pose a risk to the environment
The Agency does not have any data which suggest that Cr(III) will oxidize to Cr(VI) in  a landfill, and thai if
managed properly, the wastes indicated in Pan 261.4{b)(6)(i)(A) will not pose a threat to human health and
the environment.  The Agency will, however, be  pleased to receive and review any such  data which you
forward to us.

In your second question, you expressed concern that the TCLP is not a realistic indication of the long-term
stability/mobility of elements in solid wastes, and requested additional information on the choice of
experimental conditions used in the test.  The TCLP was developed to model teachability of hazardous
constituents in a specific waste management scenario,  e.g., co-disposal of solid waste with municipal waste in
a sanitary  landfill. The test is not expected to model other waste management conditions.  Data from the
test are useful for comparison against toxitity standards, or against other TCLP data sets, only when the
single specified set of experimental conditions are used.  I am including with this  letter (as Attachment 1)
additional information that discusses the rationale and process for selection of experimental conditions.

Finally, in your third question, you asked which analytical methods should be used to determine the
concentrations of total cyanide and cyanide amenable  to chlorination.  I  have enclosed the appropriate
methods (Methods 9010 and 9012 from Test Methods for Evaluating Solid Waste. Physical/Chemical
Method* (SW-846)) to this letter as Attachment 2.

If I may be of tether mitfancc, please do not hesitate to contact me.

     Characteristic Hazardous Waste


    A manufacturer generates used oil that
 exhibits the toxicity characteristic (TC)for lead
 (D008). On one occasion, the used oil is mixed
 with an unlisted spent solvent that is hazardous
 due to the characteristic of ignltability (D001)
 and the TCfor benzene (DOJ8).  On another
 occasion, the used oil is mixed with a spent
 solvent that is hazardous solely because it
 exhibits the characteristic ofignitability
 (D001). After mixing, both wastestreams
 exhibit only the TCfor lead and are sent to be
 burned for energy recovery in an industrial
 boiler.  Do both mixtures qualify for regulation
 as used oil under 40 CFR Pan 279 standards
for used oil management?

    The first mixture must be managed as
 hazardous waste (D008) and  the second
 mixture must be managed as  used oil. Section
 279.10(b)(2) specifically addresses mixtures of
 used oil and characteristic wastes, drawing a
 critical distinction between the two mixtures
 described above. The first mixture is addressed
 in §279.10(b)(2)(i), which  states that a mixture
 of characteristic hazardous waste  and used oil
 must be handled as a hazardous waste if it
displays anv. characteristics of hazardous waste.
This section applies to any mixture of used oil
and characteristic hazardous wastes, other than
wastes that are hazardous solely because they
exhibit the characteristic of ignitability. Since
the first mixture contains a characteristic
 hazardous waste that is hazardous because of
ignitability ajod toxicity, and the mixture
continues to display the TC for lead, it is
considered hazardous waste.  In order to
qualify for classification as used oil, this
mixture must be free of all  characteristics,
including those originating from the used oil
(D008) and those stemming from the
hazardous waste (D001 and D018).
    Section 279.10(b)(2)(m) addresses the
 second mixture and is more specific. It dictates
 that a mixture of used oil and a characteristic
 hazardous waste, which is hazardous solely
 because it displays the characteristic of
 ignitability, may continue to be managed as
 used oil provided that the resulting mixture is
 not ignitable. Since the second used oil/waste
 mixture is no longer ignitable, it is classified as
 used oil, even though it still displays the TC for
 lead (D008).

   The difference in these two scenarios is that
 used oil that is mixed with a characteristic
 hazardous waste (other than a solely ignitable
 waste) must be free of all characteristics to
 qualify for classification as used oil, whereas
 used oil that is mixed with a waste that is
 hazardous solely due to ignitability needs only
 to be void of the ignitability characteristic to be
 considered used oil. The difference in the two
 scenarios is critical because used oil often
 inherently exhibits a characteristic of
 hazardous waste.

   The standards in Pan 279, while tailored to
 used oil handling, do not negate the
 requirements placed on handlers by the
 hazardous waste regulations, and mixing an
 ignitable waste with used oil to render the
 waste nonhazardous constitutes treatment
 of hazardous waste and is subject to all
 appb'cable hazardous management
 standards, including permitting (50 £R 49180;
 November 29,1985).

   Note that Part 279 standards, other than
 those related to burning and marketing, are
 effective March 8,1993, in unauthorized states
 only and in authorized states they are not
effective until those states amend  their
program to incorporate the standards.
 Standards regarding the marketing and burning
of used oil for energy recovery are simply
transferred from existing Pan 266 regulations
and remain in effect.

Dear Ms. Schiller:

     Thank you for your January 25 letter regarding  the
availability of criteria and/or guidelines EPA uses  in  evaluating
the characteristic of reactivity.

     EPA currently has a test procedure  in place that evaluates
the reactivity of waste which releases hydrogen  cyanide or
hydrogen sulfide gas when mixed with a weak acid.  EPA  has  not
proposed a test method for evaluating a  waste which  releases
hydrogen gas when mixed with water.  I have enclosed with this
letter a copy of the Agency's supporting guidance  for the
reactivity characteristic.  This guidance explains EPA's position
and rationale for developing this characteristic.  In addition,
Appendix 3 of this document describes and evaluates  available
reactivity testing methods, one of which is for  water reactivity.
This may provide you with a guideline for evaluating waste  that
may be reactive with water.

     EPA attempts to define our hazardous waste  characteristics
in terms of specific, numerically quantified properties
measurable by standardized and available testing protocols.
However, in the case of reactive wastes, it is difficult to
construct a numerically quantified definition of reactive wastes
because the term "reactivity" embraces a wide variety of
different  (although overlapping) effects, each of  which can be
triggered by an equally wide variety of  initiating conditions  or
forces.  Further, the properties embraced by the term reactivity
are relative properties.  The determination of whether  something
"reacts vigorously with air or water" or is "unstable with
respect to heat or shock" is a relative  determination,  not  an
absolute one.  Because the effects being measured  proceed along a
continuum, it is difficult to draw the line at any particular
point.  EPA is currently looking into procedures for testing
wastes for hazardous characteristics, and determining wastes that
react with water is a part of this research.

      Dear Ms. White:

           Thank you  for your letter  of  March 18, 1993  concerning the
      November  24,  1992  Federal Register  notice on  revisions  to the
      Toxicity Characteristic Leaching Procedure  (TCLP).

           In response  to your first question regarding  the conditions
      under which the method of standard additions (MSA) must be run for
      metallic contaminants  in TCLP samples, both conditions  listed in
      the FR notice must  be met  before MSA  is  required.   These criteria
      are linked together.   Unless both  are met, MSA is  not  required.
      The intent here is to lighten the  burden on laboratories.   If a
      waste is clearly hazardous  or clearly non-hazardous further testing
      is unwarranted.   It is those cases where the analyte is'hear the
      regulatory limit  that additional work is  required to  prove its
      "true" concentration.

           Your  second  question  concerns  the  proper  procedure  for
      administering  the  method  of standard  additions,  when  MSA  is
      required.   You  should  do the full 4 point  procedure as  stated in
      the Federal Register notice.  This overrides the QC procedures for
      MSA found in Method 7000 and  6010.

           I hope that this information will be of use to your analytical
      program.  If you  have  any further questions, please feel  free to
      call me at (202)  260-4778.

FROM:     David Bus sard, Director  'V U2t*^4^e^*'

     This memorandum responds to your memorandum to Bruce  Diamond
dated March 11, 1993 requesting clarification of the term
•'aqueous11 as it applies to the corrosivity characteristic.   Your
memorandum references a September 1992  "Hotline Questions  and
Answers" publication produced by the RCRA/ Super fund Hotline
contractors and concurred upon by my Division and by OSW.

     The Hotline publication correctly  defines "aqueous",  for the
purposes of the corrosivity characteristic, to mean in a form
amenable to pH measurement.  This interpretation is consistent
with the supporting documentation found in the background
document for the corrosivity characteristic final rulemaking
(Background Document: Section 261.22 -  Characteristic of
Corrosivity, May 2, 1980).  I have attached the applicable
section for your information.

     A more specific interpretation of  "aqueous" for the purpose*
of the corrosivity characteristic may be found in the method
referenced in the actual regulatory text for the corrosivity
characteristic at 40 CFR 261.22(a) (1) .  The regulation states
that "[t]he EPA test method for pH is specified as Method  5.2 ;n
"Test Methods for the Evaluation of Solid Waste,
Physical/Chemical Methods" (see attachment).  Method 5.2 EH
Electrometric Measurement, which was renumbered to Method  9040,
specifies under scope and application that the method "is  ua«d to
measure the pH of aqueous wastes and those wastes where the
aqueous phase constitutes at least 20%  of the total volume of ..*»•
waste."  Therefore, any waste for which this method is applicaa.e
must contain at least 20% free water by volume.  This method i«

fuel or fuel addititve could, in fact, constitute a legitimate
type of burning for energy recovery.  It is important to note,
however, that energy value is not the sole determinant of whether
the natural gas condensate is being legitmately burned as a fuel.
Additional shain .recycling criteria, identified in the January 8,
1988 Proposed Amendments to the Definition of Solid Waste, are
equally relevant to a regulatory status determination  (see 53 FR
at 522; see also 48 FR at 11158  (March 16, 1983)).  Of particular
relevance to a determination regarding  natural gas pipeline
condensate is whether the condensate contains toxic constituents
not found in normal fuels and if so, whether these constituents
contribute to the recycling objective or are simply being
destroyed.  Assuming that burning is for legitimate energy
recovery, high energy value natural gas condensate would not be
considered a RCRA solid or hazardous waste when used as a fuel or
fuel additive.  However, the determination would have to be made
case-by-case based on the facts relevant to both the specific
material and the manner in which it is being burned.

     It is also important to note that authorized states
generally implement the RCRA hazardous waste regulations and
State regulations may be more stringent than the Federal
regulations.  I hope this letter has addressed your concerns.  If
you have any further questions, please contact Mitch Kidwell or

SUBJECT: Paint Filter Liquids Test  Technical Guidance

Dear Dr. Schrader:

     Thank  you  for  your  letter of  February  4,  1993,  and  our
subsequent  discussions  in  which you raised questions about  the
applicability of the Paint  Filter Liquids  Test  (PFT,  Method 9095)
to the  sorbent industry.   The test  determines if a  free  liquid
exists for the purposes of  the Liquids  in  Landfills Rule.

     Five  items  in particular seem to be of concern to  sorbent
manufacturers, users, and landfill operators in complying with the
Liquids  in Landfills Rule: (1)  the  light  bulk  density of  some
sorbents, which  causes  them to overflow the  filter,  (2)  the  need
for clarifying that sorbents and  sorbates are to be uniformly mixed
prior to placement in the paint  filter,  (3)  the size and  shape of
sorbent pillows, socks, and pads, which prevents them from fitting
into  the  paint  filter  without  modification,   (4)  the  need  to
standardize filter paper specifications, and (5)  the need to  test
each sorbate/sorbent combination.

     With regard to the first item,  if a 100-g sample of sorbent is
of such low density that it would overflow the filter (potentially
causing liquids to flow between  the filter and  funnel, yielding a
false positive),  then two  options  exist.   First, the procedure
specifies a  "100-ml  or  100-g representative sample,"  so a  100-ml
rather than a 100-g sample may  be used,  if the  material  can  be
measured volumet:  ^ally  (i.e.,  lacks major air spaces or voids).
Second, the sides .

the sorbent after the sorbent has been placed in the paint filter.
The sorbent and liquid material should be thoroughly and uniformly
mixed and then a representative sample placed in the filter.

     Regarding the third item, the PFT does  not  address how
material such as sorbent pillows,  socks, pads,   sheets, and rolls
should be placed into the paint filter.   How such items are placed
into the  filter could  result in significant variations  in test
results.   As this  is  a  gravity test  with no  external   applied
pressure, it is  not intended for sorbent pillows, socks, etc. to be
squeezed or compressed to fit  into the paint filter.

     In order to assure uniformity and standardization of the test,
a  100-g  or 100-ml sample of  sorbent pad,  roll, sheet,  or other
material which does not conform to the shape of  the paint  filter,
should be cut into small pieces and poured into the  filter.  Sample
size reduction may be accomplished by cutting the sorbent material
with  scissors,  shears,  knife,  or  other  such   device so as  to
preserve as much of the original integrity of the sorbent fabric as
possible.  Sorbents enclosed  in a fabric should  be mixed with the
resultant  fabric  pieces.   The particles to be  tested should be
reduced smaller than 1  cm  (i.e., should be capable  of  passing
through a  9.5 mm  (0.375  inch)  standard sieve).   Grinding sorbent
materials  should be  avoided as this  may destroy the integrity of
the sorbent and produce many  "fine particles" which would normally
not be present.

     For brittle materials  larger than 1 cm that  do not conform to
the  filter,  light  crushing  to reduce  oversize  particles  is
acceptable if it is not practical to cut the material.  Materials
such as  clay,  silica gel,  and some  polymers may  fall into  this
category.

     Regarding the fourth item,  the  PFT specifies  "Conical paint
filter;  Mesh  number 60 (fine meshed size).  Available at local
paint  stores   such   as Sherwin-Williams  and   Glidden  for  an
approximate  cost  of  $0.07  each  [as of  September  1986]."   EPA
recognizes that most paint filters today are not  labelled by actual
mesh size,  and that  the specified "fine  meshed size" available
commercially  is actually  a  mesh size  of  60   X  48   threads  or
holes/inch.  Since this is coarser than a 60  X 60 mesh, it has the
potential  to give more  conservative  test results (i.e., may  fail
more samples) and is therefore acceptable to EPA, as would be a 60
X 60 mesh.   Mesh sizes greater  (i.e.,  finer) than 60 X 60, however,
would not be acceptable.

     Regarding the fifth item,  no materials, whether sorbed or not,
may be placed in a  hazardous  waste  landfill if  they release  free
liquids  as determined  by the PFT.   This should  be  implemented
through the landfill operator's Waste Analysis Plan (WAP).  The WAP
should  identify when samples  will be  tested using the PFT.   In
cases of controlled treatment by sorbents,  it may not be necessary

-------
                           Page 3 of 3

to test each treated sample if sufficient data have been obtained
by  testing  each  sorbate/sorbent  combination  to establish  the
loading ratio that assures no  free  liquids,  and the treatment is
done to assure such ratios are  not exceeded.  Each sorbate/sorbent
combination  should be  tested  because  sorbents have  different
sorption characteristics and sorption ratios based on the type of
sorbate (e.g., oily vs water-based sorbates) .

     As we discussed, this  test is not  designed to  evaluate the
efficiency of a sorbent  product relative  to other sorbents.  It is
designed to determine if a specific  sample, be it sorbent or other
material, contains free liquid and thus should not be placed in a
hazardous waste landfill.  As discussed under item 5 above, the PFT
may also be used to determine the "saturation" or pass/fail level
of a  particular sorbent /sorbate combination.   Our  testing shows
that at the  "saturation"  level  some failures  may occur since the
"saturation" level is more a range  than  a  line,  but  that at some
lower  liquid loading  level,  that can  be determined  in  the lab,
passing  the  PFT  is  consistently  achieved.    This knowledge  is
invaluable  to  a  treater  using  sorbents  to  assure  successful
treatment  (i.e.,  a high  pass  rate).   It  is less valuable when
sorbents   are   used   to  control   or   clean  up  spills   since
sorbate/sorbent ratios are less controlled.

     I hope  this  information will help clarify technical details
about  the applicability  of  the Paint  Filter  Liquids  Test  to
sorbents and assist you in your analytical program.   EPA plans to
incorporate  appropriate parts  of  this  technical guidance  into
Method 9095 when we propose a third  update to the third edition of
SW-846.  Realistically the proposal and promulgation of this update
is several years away, so I hope this technical guidance will serve
your purposes in the interim.

TO:          Larry Brill, Chief
              MA Wasie Management Branch
              Region I

       I an: writing in response to your October 6, 1993, memorandum asking for
clarification on the level of sulfide for determining if a waste is hazardous under the
reactivity characteristic.

       The regulation in 40 CFR 261.23 defines reactive wastes to include "cyanide or
sulfide bearing wastes which, when exposed to pH conditions between 2 and 12.5, can
generate toxic gases, vapors or fumes in a quantity sufficient to present a danger to human
health or the environment".  This definition is intended to identify wastes that, because of
their extreme instability  and tendency to react violently or explode, pose a problem at all
stages of the waste management process.  The definition is to a large extent a paraphrase of
the narrative definition employed by the National Fire Protection  Association.  The Agency
chose to rely almost entirely on a descriptive, prose definition of reactivity because most of
the available tests for measuring the variegated class of effects embraced by the reactivity
definition suffer from a number of deficiencies.  For determining reactive  sulfide content in
particular, one of the deficiencies is poor recovery.

       Chapter 7 of SW-846 contains the method for determining total releasable sulfide. It
should be noted that different versions of the test method have existed that yield  substantially
different results.  In September of 1990, EPA proposed increasing the strength of the sulfuric
acid used in the test from 0.01N to 0.1N.  The Agency reevaluated the stronger  acid
digestion and concluded that the original acid concentration of 0.01N more accurately
represented  the mismanagement scenario the method is designed to emulate (see attachment
1). In 1992, EPA revised the method to include the original sulfuric acid  concentration of
0.01N.  This version was finalized on August 31,  1993 (58 FR 46040, attachment 2).  The
current EPA guidance level is 500 mg/kg for total releasable sulfide.  If a waste contains
greater than 500 mg/kg  total releasable sulfide, then the waste is  usually considered to meet

-------
the narrative definition of a characteristically reactive waste under 40 CFR 261.23.  Since
recovery can be as low as 10% under certain circumstances, any test result greater than 500
mg/kg would be deemed a characteristic hazardous waste.

       In your letter you included data on slaker grit and green liquor dregs  wastestreams
from an International Paper facility.  It is unclear which version of the test method was used
to measure total releasable sulfide.  If the most recent method (attachment 3) was used, then
the wastestreams have  concentrations in excess of 500 mg/kg (684 mg/kg and 1004 mg/kg
respectively), and would therefore be considered a hazardous waste.  If there is any question
as to which version of the method was used I recommend having the analysis repeated using
the most recent method.  The older proposed method employing 0.1N sulfuric acid would

     Dear Mr.  Siegel:

          Thank  you for your November  16,  1993  letter in  which you
     requested  guidance  on  whether  or  not  any  Federal  disposal
     guidelines  apply to the disposal of metal casings containing spent
     powdered metallic  oxide catalyst  (i.e.,  manganese dioxide and
     copper oxide).  Based on the Material Safety Data Sheet  (MSDS) you
     provided,  manganese  dioxide is  a strong  oxidizer which  reacts
     exothermally,   may  ignite  certain  organics,   and  cause  lung
     irritation  or  serious  central  nervous  system disorders  through
     inhalation.

          The spent catalyst  is not a listed  hazardous waste  under
     Federal regulations.  However, the spent material  may  need to be
     tested to  determine if it  exhibits any of  the hazardous  waste
     characteristics  identified  in 40  CFR  261,  Subpart  C  (i.e.,
     ignitability,  corrosivity,  reactivity,  toxicity).   The  limited
     information provided  suggests that  the catalyst  may  exhibit  a
     hazardous waste characteristic of ignitability or  reactivity.  Even
     if  it   is not ignitable or  reactive,  when  the spent catalyst is
     discarded,  its characteristics may be different  (e.g.,  it  may be
     contaminated with other hazardous constituents).   Therefore, you
     must   determine  if  the  waste  contains  any  of   the  Toxicity
     Characteristic (TC)  constituents listed in Table 1 of 40 CFR 261.24
     at levels of regulatory concern.

          If the spent catalyst powder is determined to  be a hazardous
     waste,  then it must be handled according to  the hazardous waste
     regulations  under the  Resource  Conservation and Recovery  Act
      (RCRA).   Even if the  spent   catalyst  is not  a  characteristic
     hazardous waste,  the nature of the material  (a  strong oxidizing
     agent)  may still  require  special  handling.   To insure  full
     compliance  with state's solid  waste regulations and safe handling
     and  disposal of the metal  casings,  you should contact  the waste
     management  authority  of the  State in  which the  waste will  be
     handled,	•

Dear Mr. Igli:

     In EPA'e letter of November 10, 1993, the Agency  stated  that
mercury batteries, meeting specific criteria, are not  considered
debris under the current definition of debris (see  57  FR 20767,
May 15, 1992).  In your follow-up letter dated November  23, 1993,
you requested further examination on whether certain mercury
batteries are hazardous debris.  In your letter you discussed,
among other things, the fact that debris capacity variances are
based on both the Mold" and current definitions of  debris.

     The Agency's determination that the battery carcasses
described in your April 30, 1993 letter are containers and not
debris has not changed.  In the context of a capacity  variance,
you are correct that both the "old" and current definitions
apply.  As you point out, the old definition includes  containers
as being debris (55 FR 22686, 22650, June 1, 1990).  EPA re-
addressed this issue in the "new1* definition, stating  that in
many cases debris will be mixed with liquids or sludges,  and  that
EPA will determine on a case-by-case basis whether  all or
portions of such mixtures should be considered debris  (55 FR  at
22650).  However, this does not necessarily mean that  the
materials to which you refer are entitled to a capacity  variance.
For example, it would not be appropriate to provide such a
variance to a drum (i.e., container) of liquid waste or  sludges.

     In your specific case, the EPA Regional office has  informed
us that the mercury sludge contained in the battery carcass does
not meet the definition of debris, and that the mixture  (i.e.,
battery carcass and mercury sludge) also is not debris.

     To address other questions regarding battery carcasses
containing hazardous waste sludges or mixtures of debris and
hazardous waste sludges, please contact Mr. Richard Kinch, Chief

    MEMORANDUM

    SUBJECT:  Debris and Soil Contaminated with Explosive Residues

    FROM:     James F. Michael, Chief
              Disposal Technology Section  (5303W)
              Office of Solid Waste

    TO:       Lawrence A. Wapensky, Chief
              Utah/North Dakota Section
              Region VIII


         This responds to your January 20,  1995 memorandum requesting
    assistance in answering questions  raised by the State of Utah
    concerning regulatory issues pertaining to wastes contaminated
    with explosive residues.

         The first question raises concern with the reference at
    40 CFR 261.23(a)(8) to certain Department of Transportation (DOT)
    regulations concerning explosive classifications, that are cited
    as criteria for determining the characteristic of reactivity.
    The DOT regulations cited at §261.23(a)(8)  have recently been
    changed and expanded to conform with Department of Defense hazard
    classes, therefore, presenting difficulties in implementing the
    Federal regulatory definition of reactivity under RCRA.  Until
    such time that §261.23(a)(8) is updated,  those referenced DOT
    regulations can not be used for determining reactivity.'
    Reactivity determinations should be made using the remaining
    criteria at §261.23(a)(l)-(7).

         The second question asks whether  and when liquid, solid, or
    debris mixed with explosives would be  considered reactive.
    Wastes, whether themselves explosives,  or media contaminated with
    explosives would be considered reactive by meeting the definition
    of reactivity as described in §261.23(a)(l)-(7).  Wastes that do
    not meet the criteria in §261.23(a)(l)-(7)  would not be
    considered reactive.

         The third question regards other  Federal criteria for
    explosivity.  If agencies such as  the  Bureau of Alcohol, Tobacco,
    and Firearms  (BATF) have regulations,  or protocols, for
    determining whether or not a substance is explosive, those
    regulations or protocols would not be  enforceable under.EPA.

regulations, unless they became incorporated into our rules.
Specific methods used by agencies such as BATF to determine if a
substance is an explosive could, however, be applied to determine
whether a waste is reactive according to §261.23(a)(6) or  (7).

     Thank you for the opportunity to address questions related
to the reactivity characteristic as it relates to explosives.  If
you have any questions, please call Jeff Gaines at  (703) 308-

Dear Mr. Nebrich:

       Thank you for your letter of July 31,1995 requesting a clarification of the
difference between the definition for the characteristic of ignitability as it pertains to
solids vs. liquids.  As you are aware, there is no officially promulgated or required
method for determining the ignitability of solid samples or sludges at this time. Of the
two flash point methods, Method 1010, Pensky-Martens, has some utility for liquid
samples with non-filterable, suspended solids.  If your samples contain filterable solids,
they are not amenable to the Pensky-Martens flash point test Flash point testing is only
appropriate for liquid samples. It should not be applied to solids.

       The Office of Solid Waste has developed and proposed a test to determine the
ignitability of solids (SW-S46 Method 1030). Our procedure is based on the Department
of Transportation (DOT) burn rate test listed in 49 CFR §173.124 and Appendix £. You
should separate the solid/liquid phases of your samples and test each phase separately;
liquids by flash point and solids by the DOT procedure.

       It is the generator's responsibility to make sure their waste is not hazardous for
the characteristic of ignitability as described in 40 CFR $26121. As we do not have a
promulgated method required by regulations to test for the igmtabflity of solids or
sludges at present, we recommend you use generator knowledge of the waste when
available supplemented by tests appropriate to the waste if necessary.  When specified
test methods are not available and generator knowledge is insufficient to make a
hazardous waste determination, it is always wise to check with your state or regional
EPA office for approval of the protocol you wish to follow in malting a hazardous waste
determination.

       There have been clarifications to our guidance on how to determine a free liquid
since the 1989 letter to Mr. Travis P. Wagner on the subject  In a January 13,1995
Federal Register Notice (60FR3089) in Section IV.C there is a paragraph on "Free
Liquids and Characteristic Tests."  A copy is enclosed for your convenience.

       Dear Mr. Shipiro:

            There has been a discussion ragging in our industry
       (hazardous waste consulting)  for the past few years regarding
       a D001 ignitable solid.  Some of our clients (generators)
       want to identify their solid  (non-liquid)  wastes as DO01 when
       .it's only based oh a  flashpoint test as  outlined
       40CFR261.21(a)(1).  They then want to ship the waste as  a  DOT
       Flammable Solid.

            We have .tried to point out that non-liquid,  solid waste
       cannot meet the definition of a RCRA characteristic of
       ignilability 40CFR 261.21 unless it is "not a liquid and is
       capable,  under standard temperature and pressure 	
       [40CFR261.21(a)(2)].  Now with the subcategories for D001  on
       a LDR Notification it makes it even more difficult  to
       identify a D001 solid as ignitable since there is no category
       which fits a Flammable Solid  in 40CFR261.2l(a)(1).

            Could you please clarify the difference Between the
       definition for the Characteristic of Ignitability as it
       pertains to solids (non-liquids) vs. liquids.  Has  there been
       any change since the 1989 to  letter Mr. Travis P. Wagner (see
       enclosed).

            If you should have any questions,  please  do  not hesitate
       to call.

                                     Very truly yours,

Dear Mr. Nebrich:

     Thank you  for your follow  up letter of August  31,  1995 to
Michael   Shapiro  requesting   further   clarification   of  the
characteristic  of  ignitability  as  it pertains to  solids versus
liquids.

     40  CFR  261.21 (a) (1)  is  only  applicable  to  liquids  as  a
definitive test for the characteristics of ignitability.   There is
no  promulgated  definitive  test  for  the  ignitability  of solids
(i.e., physically a solid with no free liquid) .   If a solid flashes
using some modification of the flash point test, this may  indicate
there is a potential  problem with the sample such as contamination
with ignitable volatiles and  further investigation may be in order.
The flash point  test  alone is not definitive for determining the
ignitability  of  solids, but  may be used with  other  evidence to
build a case  for a waste being classified as an ignitable hazard.

     I  hope  that  this  information  will  be  beneficial  to your
industry.   If you have any  questions, please  feel  free  to call
Ollie Fordham of my staff at  (202) 260-4778.

       response (enclosed) regarding the characteristic of
       ignitability as it pertains to solids. vs. liquids, I would
            to request a. further clarification.
            Is it possible or correct to identify a solid waste (ie.
       physically a solid with no free liquid) as RCRA DO 01
       (characteristic of ignit lability) according to 40CFR
       261. 21 (a) (1) .  I realize that you could have a RCRA D001 non-
       liquid as defined in 40CFR 261.21(a)(2) or (4).  However,
       since there are only flash points for liquids, could  you have.
       a solid waste characterized as a RCRA D001 based solely on- a
       flash point?

Dear Mr. Goodell:

     This is in response to your letter of August 1, 1980 in
which you requested confirmation of our previous telephone
conversations related to interpretations of §261.33 of the
hazardous waste regulations promulgated on May 19, 1980.  In an
attachment to your letter you described a hypothetical waste
stream which contained several constituents which, as products,
are listed in §§261.33(e) or 261.33(f); you concluded that the
waste stream was non-hazardous.

     As noted in the regulations, §§261.33(e)  and (f) relate only
to commercial chemical products  (or variants thereof) which are
hazardous wastes if and when they are discarded.  They are not to
be applied to wastes which incidentally contain substances listed
in these sections.  Thus the waste stream you described is not
one of the commercial chemical products listed.   (The exception
to this would be those cases where, citing your example, the
product is known by the generic name of and purchased for the
active ingredient, pentachlorophenol.)   Also you did properly
indicate an evaluation against the characteristics of hazardous
waste.

     A Regulatory Interpretation Memorandum (RIM) on this
specific issue  (§261.33) has been prepared and is being revised
within the Agency.  It should be published in the Federal
Register in about two weeks.  A notice indicating that RIMs would
be prepared and a tentative schedule for a group of RIMs was
published on August 19, 1980 (45 FR 55386) .  A copy is attached.

Dear Mr. Bright:

     This is in  response  to Mr.  Finis  E. Carieton's  lefct-w?  to rae
dated October 2B, 1950  (copy attached).  In his  letter  l'lr<  Carlet.on
asks for verification of  his interpretation of  our RCEA Hazardous
v:aate Menagesent  Regulations with  ressnsct to wastes  that will be
Generated by a refinery your firm  intends to build in BaHsrsfield,
 alifcrnic.  Based  on the facts  presented in his letter, I  conclude
that Hr. Carlston has reached correct  interpretations of our
regulations.

     It appears  that the  refinery  vastewater to be treated  is not  a
bazar.-5ous waste  because it is not  listed in §$261.31 or 261.32 of  the
regulations, >3ocs net contain (by  rcixture) any  of the hazardous wastes
listed in <>*-261.31  or 261.32,  or does  not exhibit any of the  hazardous
waste characteristics identified in  Scbpart C of Part 261 of  the

regulations and  it  would  not ba  necessary to submit  a Part  A  application
on Xovcnber 19,  1980, or  obtain  interim status  in accordance  with
§122.25.  I would hasten  to point  out, however,  that if any of the
three hazardous  wastes  to b« generated by the refinery  (KO48, KO49 and
KOS1) ere discharged into^an-i nixed  with the refinery wastewater,  they
will cause the wastewater to b«  a  hazardous waste--in accordance with
the mixture rule of §261.3(a) (2) (ii)~and; thereby,  subject to our
RCRA regulations.

     It appears  that on*  of the  harardous wastes to  be  generated  by
your rcfinery~nasn«ly skiianings  from the air floatation unit  (KO43}~
will be recycled to the coker after  accumulation or  storage in the

subject to our regulations (see  «261.6(a)), the storage ef  this waste
in the slop cil  tank is now subject  to our regulations  because it is

Dear Mr. Hoyle:

     •nils is in response  to your  letter  of  September 11, 1980,
requesting clarification  of our RCRA hazardous waste management
regulations  relative  to bottora sediments, water wastes &nd spilled
material and mixtures resulting from storage of petrolewn products.
You ask whether these wastes are  hazardous  wastes by virtue of
containing any of the constituents, such as benzene, list ted in
Appendix VIII of Part 261 of our  regulations.

     These wastes would only be hazardous waste if:

     1.  they are listed  as hazardous  wastes in §§261.3.* or
         261.32 of our regulations; or

     2.  they are mixtures that contain  any of the hazardous
         wastes listed in §§261.31  or  261.32 of our
         regulations.

     3.  they exhibit any of the  characteristics of hazardous
         wastes described in Subpart C of Part 261 of our
         regulations.

From the information provided in  your  letter, it appears that your
wastes do not meet either of the  first two  criteria.  Your letter
does not provide sufficient information  to  make a judgement based
on the third criterion.

     Relative to your questions about  Appendix VIII, that Appendix
is only meant to be used  by EPA in  making judgements about listing
wastes as hazardous wastes.  It is  not intended that the regulated
community must use Appendix VIII  to determine whether e waste is a
hazardous waste.  Put in  other words,  a  waste that  contains an
Appendix VIII constituent is only a hazardous waste because of this
if EPA has listed the waste for this  reason in §§261.31  or §261.32.

-------
                                 -2-


     If your wastes contain any of the Appendix VIII constituents but
these wastes are not listed in §§261.31 cr 261.32, this does net
necessarily mean that SPA has nade a determination that these wastes
are non-hazardous.  It most liV.ely means that we have not yet nade &
determination with respect to these wastes.

     I hope I have clarified our regulations with respect to your
questions.  If I can of further assistance, please call ne.

                                       Sincerely yours,

     You  indicate that your waste is CaC, Sir'2 and asbertcs and
ask if it is a  hazardous vaste.  w« listed asbestos as a hazardous
waste in  §261.33{£)  of our regulation, but this cr.ly applies tc
technical grade asbestos if, for acne reason, it is discarded or
intended  tc be  discarded.  This list-ir.g does not causr £ -r.ar.ufacturinc

a hazardous waste.   ?ron =y understanding of your letter, your waste
is such a manufacturing process waste.  If this is correct, it is r.ct
s. ':-.»sarucus waste because of its content cf asbestos.

     Your waste nay be a hazardous waste because it exhibits any of

     If you should  find that your waste is a hazardous waste and you
are a sraall quantity generator, you are allowed to Ji*?os« of your

states that, you dispose  of 300 kilograms  per  nonth of asbestos.  Cur
regulation is based  on the quantity  cf  the  tctai waste,  net -ust the
quantity  of the asbestos  or any  other constituent  in the waste.
Therefore, I cannot  ~aXc  a judgement en whether you are  a s-all cuantit*

Mr. William English
Vice-President, Operations
The Massillon Steel Casting Company
Massilon, Ohio   44646

Dear Mr. English

     This letter will confirm the conversation you had with Mr.
Myles Morse of my staff on October 20, 1980, concerning your
petition to exclude the waste of the Massillon Steel Casting
Company from the K061 hazardous waste listing, (emission control
dust/sludge from the electric furnace production of steel), under
Section 261.32 of the hazardous waste regulations.  The Massillon
Steel Casting Company's facility in Massillon, Ohio, as indicated
by your petition dated September 9, 1980, is a steel foundry and
is therefore not affected by this RCRA hazardous waste
classification.  This reflects the Agency's finalized listings
(see 45 FR 74890-892 (November 12, 1980)) which clarify that the
listing K061 applies only to the primary production of steel and
not to steel foundries.  This change was made since the listing
background document refers throughout only to primary steel
production.  We are uncertain whether foundry electric furnace
emission control dusts and sludges are sufficiently similar in
composition to warrant inclusion in the area listing, and
therefore have not included them in this listing.  Foundry
industry wastes are being evaluated and may be addressed by
future Agency actions.  At present, however, the Agency has
formally terminated further processing of this petition.  The
petition will be kept on file with the Agency for future
reference.

     Your waste stream, therefore, will not be listed as
hazardous.  You are not required to take any action as a result
of the May 19, 1980, interim final listing.  You must still
determine, however, whether your waste possesses any of the
characteristics of hazardous waste (i.e., reactivity,
corrosivity, ignitability or EP toxicity) as provided in §262.11
of the regulations.  If your waste does not possess any of these
characteristics, you will be deemed a generator of hazardous
waste, and be required to manage the waste under the hazardous
waste management program.  It should be noted that if your waste
meets any of the four characteristics, you should have already
obtained an EPA identification number by August 18, 1980.
        This has been retyped from the original document.

     Please feel free, to contact Mr. Morse if you have any
questions or problems.  Mr. Morse's telephone number is (202)

     Dear Mr. D'Aloia:

          I am responding to  your letter of March -2~, 1983 to Alan
     Corson requesting  a clarification of why-the Agency does not
     identify as  a hazardous  waste any manufacturing waste that
     contains any of the compounds ilsted in 40 CPR 261.33.

          The commercial chemical products regulated under $261.33
     are generally products containing high concentrations of toxic.
     chemicals or, in the case of pesticides, products of high
     toxic activity. Thus, there is no question that such materials
     are likely to meet the criteria for listing, as hazardous wastes.

          Manufacturing process  wastes, on the other handf generally
     contain only low levels  of  these materials.  Thus, expanding
     the hazardous waste identification regulations to encompass
     all manufacturing  wastes containing the S261.33 compounds is
     likely to result in many false positives (i.e., wastes identified
     as hazardous which do not actually contain hazardous levels
     of the toxicants of concern) unless, and until, minimum
     concentration theresholds can be established for eacfc compound.
     At this time, due  to the- lack of data, the Agency is unable
     to set* thresholds  for all the compounds.  As the comment to
     $261.33 explains^  where  the Agency deems a manufacturing
     process waste to be ^ hazardous waste because it contains
     low levels of these compounds, such a waste will be listed
     in $5261.31 and 261.32.

          In summary, $261.33 was not broadened to include all
     process wastes due to the problem outlined above and the
     technical difficulties in establishing de minimis concentration
     thresholds for all the compounds.

                             -2-

     I hop* that I have answered your question.  If you need
additional background information on these regulations, r
suggest that reviewing the $261.33 Background Document may be
useful.

 Dear Mr. McNeiil:

      I am writing in response to your letter of June 9, 1981
 to Mr. Alan Corson requesting clarification of the section
 261.33 regulations with respect to a  sulfuric acid catalyst
 you use.

      The hazardous waste listing P120 in section 261. 33 (e)
 relates to all the oxides of  vanadium's +5 oxidation state.
 If the Monsanto Catalyst that you employ in the production of
 sulfuric acid does not have such an oxide  as its sole active
 ingredient,  then the catalyst is not  regulated under section
 261.

      One must keep in  mind however that,  even if it. is not
 regulated  under section 261.33,  the waste  must still be
 evaluated  to determine if it  exhibits any  of the characteristic
 of  a  hazardous waste (i.e.,  ignitability,  reactivity,
 corrosivity,  EP toxicity).

      I trust the above answers  your questions.  If I can be
 of  further assistance  please  give me  a call at (202) 755-9187.

Dear Mr. Reoughs

     This letter is in response  to your  request  for a
clarification of the hazardous waste  listing  1052, "Tank
bottoms (leaded) from the petroleum refining  industry."   In
our telephone conversations, you indicated  that  your company,
as well as other pipeline companies,  generate leaded tank
bottoms at bulk terminals, distribution  points,  etc., which
are not part of a refinery.  Therefore,  it  was not clear  to
you whether the listing 1C052 included all leaded tank bottoms
generated by the petroleum industry or just those specifically
generated at a petroleum refinery.

     As you had discussed with Matt Straus, of my staff,  on
the telephone, the hazardous waste listing  K052  is limited
to only those leaded tank bottoms which  are generated at  OE
as part of a petroleum refinery.  A petroleum refinery is
described in the listing background document  as  a ••••complex
combination of interdependent operations engaged in the
separation of crude oil by molecular  cracking, molecular
rebuilding and solvent refinishing, to produce a varied list
of intermediate and finished products...*  (Background Documents
SS261.31 and 2€1.32 - Listing of Rasardous  Wastes (FinaHsafeion
of May 19, 1910 Hasardous Waste  List), November  14, 19SO, p.
685.] Therefore, only leaded bottoms  from those  tanks {i»e.,
tank farm) which are directly part of a  petroleum refinery
(i.e., used to store product/crude prior to shipment off-site)
and which generate leaded bottoms would  be  currently covered
by the listing.  These leaded bottoms are subject to control
as hazardous wastes when they are removed from the tanks.
This we believe is made clear in reading the  listing background
document which defines the scope of the  listing.

-------
     This, however, does not mean that your bottoms are non-
hazardous.  Each generator is ultimately responsible for
determining whether this waste exhibits any of the charac-
teristics of hazardous waste (i.e., ignitability, corrosivity,
reactivity and EP toxicity) as provided in 1262.11 of the
regulations.  If the waste exhibits a hazardous waste charac-
teristic, the facility will be deemed a generator of hazardous
wasto, and the waste must be managed in accordance with the
hazardous waste management regulations.  In addition, if, in
further studies, the Agency determines that leaded tank bottoms
generated from other sources are also hazardous, the Agency
will amend the listing to include these sources under Subtitle
C control*

Dear Mr. Sato:

    I am writing in response to your letter of July 23, 1981  (£-5-3;
IX81-SCRA-079) requesting clarification of 40 CFR 261.33(e)..

    You are correct in your interpretation that a material containing a
compound listed in §261.33(e) as  its sole active ingredient is a hazardous
waste when discarded even though  the original product has been diluted by the
user.  Thus if a person purohas«s z  concentrated sslution of the pesticide
Aldicarb (P070) and then dilutes  it  to an application strength solution; disposal
of the application strength solution is considered to be disposal of the product
itself.  A literal reading of the regulations would mean that even if the
amount of chemical product prior  to  dilution was less than 1 kilogram, disposal
of more than 1 kilogram/month of  the application strength solution would require
management as a hazardous waste.

    It is important to keep in mind, however, the applicability of the "fanner
exemption" discussed in §262.51.  A  commercial applicator working for a farmer
may mix, apply, rinse and dispose of pesticide rinsate or unused pesticide
solution on the farmers property  if  done so in accordance with the instructions
on the pesticide label.  This exemption would not apply if the pesticide were
being applied to more than one fanner's property and disposal only, occurred at
one farm, or if the waste was shipped off the farmers's property for disposal.
    I trust that this explanation clarifies the issue for you*
any further questions, please feel free  to give us a call.

Re:  Request for Policy Statement regarding J261.33(e) of
     Title 40 of the Code of Federal Regulations

Dear Mr. Friedman:

EPA  Region  9  is  currently  engaged  in  an enforcement  action which
involve* an interpretation of §26l.33(e) of Title 40, Code of Federal
Regulations.

It is our contention  that  a  pesticide  containing a listed 5261. 33 (e)
chemical product  as its sole  active ingredient which  is  diluted to
application strength  i« a-  hazardous  waste   if discarded.  We contend
that such  application-strength pesticide  is  a hazardous  waste even
where the chemical product prior to dilution is less than 1 kilogram.
Therefore,  so  long as  an  applicator  generates 1 kilogram  of waste
pesticide residues  per month he  is  required to notify as a generator
pursuant to section 3010 of RCRA.

Within  our  own technical  section  there has been  some  dispute as to
whether the preceding  analysis  is correct.  In order to obtain guidance
on this matter  I  contacted your  office on July 20, and  explained our
position to  Mr.  Matthew Straus.   Mr.  Straus  stated  that  Region 9's
interpretation of $£61.33(e) is correct.

Furthermore, Mr.  Straus indicated that  if the applicator tanks were
rinsed, that rinsate could be considered hazardous waste as well.

I  am writing to  obtain a  written  statement  from your office which
confirms Mr. Straus1 conclusions.  Such a statement will  greatly assist
us in the successful conclusion of our enforcement action.  If you have
any  questions regarding this request please call me at  FTS 556-8000.

Thank you for your  assistance.

Sincerely yours,
 Reed Sato

Regulation of .Paint Filters

David Friedman, Manager
waste Analysis Program (WH-565B)

Chet McLaughlin, Chief
State Programs Section (Region VII)

     Recently you indicated that the States of  Iowa and Kansas
have raised questions concerning the regulation of paint
filters removed from spray booths.  The questions revolve
around how we regulate those filters which are  hazardous
wastes when removed from the spray booth but not after immersion
in water.

     I will try to answer the specific questions raised in
your memo (a copy of which is attached).

     1.  In calculating the quantity of hazardous waste
generated, it is the weight of spent filters (including
occluded paint) that is used.  Generators are responsible
for evaluating their waste to determine whether it is a
hazardous waste or not.  If necessary they may  have to test
their waste to make such an evaluation.  However, many tines
testing is not required.  The necessary evaluation can be
made on the basis of engineering calculations.  If the water
fails the EP toxicity test it is also a hazardous waste and
its weight would be added to that of the filters.

     2.  Waste paint filters are handled the sane as any
other hazardous waste relative to the small generator exemption.

     3.  I am not sure why this particular waste needs special
treatment in the hazardous waste system other than perhaps
for a streamlined system of obtaining treatment permits for
the hazard mitigation operation (the 55 gallon  drum filled
with water).  Except in the case of the EP Toxic waters, the
immersed filters are not hazardous wastes and can be placed
in a sanitary landfill at will, whether the generator is a
large or small generator.

     I hope I have answered your questions.  If not give me a
call at 8-755-9187 (382-4806 after September 3U).

Regulation of Paint Filters

Chet McLaughlin, Chief
State Programs Section

Allan Corson, (WH-565)
Chief Waste Characterization Branch
            The State of Kansas and Iowa have raised a series  of  problems with
            the regulation of paint filters from pray booths especially those
            generated infrequently and in small  numbers.   When these filters
            are removed, they can be subject to  self ignition  and are usually
            treated by immediately immersing them in water.  Typically these
            individual filters are then transporter to a  nearby sanitary
            landfill and immediately buried to prevent auto ignition.  This
            produces the potential for the container, water, filter and waste
            to become hazardous waste subject to handling as such.

            The alternative is to allow the filter to ignite and  burn
            releasing small quantities of potentially hazardous air
            contaminants and handling of the ash a appropriate.

            The questions raised by the states on this subject are several:

            1.    Do they consider the weight of the paint or  paint and filter
            for the generation quantity?  Does the container and  water have to
            be tested before it can be disposed?  If the  water fails the EP
            toxicity test must it be handled as  a hazardous waste?

            2.    Do they have to require the handling of filters as a
            hazardous waste at firms where other wastes achieve the 1000
            kg./mo level and allow others to be  treated as small  quantity
            generators able to use sanitary landfills?

            3.    Assuming the petition route is not appropriate, the use of
            enforcement discretion is apparently the only available mechanism
            to allow the states to assume equal  treatment and  safe handling of
            this particular wastes?  Are others  under consideration?

            4.    Can they anticipate any regulation interpretation memorandum
            on this related subjects in the next several  months?

     In your letter of *pril 4, 1983, you requested  that             NJ
EPA confirm your interpretation of the RCRA hazardous  waste          ^
regulations as they pertain to the spent solvent  listings,

addresses your concerns.                                             ^

     As stated in your letter, the solvent  listings (EPA  Hazardous   *
waste Nos. F001-P005) pertain to spent solvents  (i.e.,;solvents      ~
used for their solvent properties).  Industrial process waste        »
containing solvents, on the other hand, are not included  in          1?
the solvent listings except to the extent that it is a mixture       ~
of a solid waste and a spent solvent.  Thus,  you  are correct         'f-
in stating that spent 1,1,1-trichloroethane generated  from a         ~
cleaning process is considered EPA Hazardous  waste  NO. P002,         %
while industrial process waste containing 1,1,1-trichloro®thane      o
as a contaminant are not listed spent solvents.   These wastes,       2
however, may be listed individually under Subpart D of  the           •*
regulations.

     Leachate froa a sanitary landfill that has received  listed
wastes is also considered a hazardous waste.   However, as you
stated, leachate containing POOS listed solvents  is only  hazardous
to the extent that it exhibits the characteristic of ignitability.

     Should you have any questions, please  feel  free to give *ie
a call at (202) 382-4770.

          Interpretation of Scope of K061

          The K061 waste listing is defined under 40 CFR  Section 261.32 as "Qnission
          control dust/sludge from the primary production of steel  (T)."

                   This applies to steel produced in electric furnaces, not blast
                   furnaces.

                   The listing does not include foundries.

                   Facilities that use scrap steel as a raw material are included
                   in the listing.

                    The listing does not include iron making.

          If a facility produces steel in an electric arc furnace using steel
          scrap,  the emission control dust meets the listing of K061.  fthat is
          done with the steel after this process does not affect the process
          wastes' inclusion in the listing.

     This memorandum is in response to your question regarding
the scope of the cyanide listings for metal heat treating
operations  (EPA Hazardous Waste Nos. F010, F011, and F012).  In
particular, you asked whether the form of cyanide (i.e..  complex
cyanide or free cyanide) was germane in determining whether one
had a listed waste.  In short, the answer is no.  In listing
these wastes as hazardous, the Agency was (and is still)
concerned with the management  (or management) of cyanide wastes
(both complex cyanide and cyanide salts).  If the Agency felt
that a distinction was necessary, it would have done so in the
listing.  For example, EPA Hazardous Waste No. F012 would have
been listed as follows:

     "Quenching wastewater treatment sludges from metal heat
     treating operations where complexed cyanides are used in the
     process (except for precious metals heat treating quenching
     wastewater treatment sludges)."

In addition, you should be aware that the form of cyanide often
changes during the heat treating operation or subsequent
treatment; therefore, although you may begin with cyanide salts
(free cyanide)  your waste may be primarily complex cyanide.  The
waste listings take this into account by differentiating between
the form of cyanide present in the waste (i.e., only cyanide-salt
containing wastes  (free cyanides) are listed as posing a
reactivity hazard).

     Furthermore, it should be noted that although complex
cyanides are less toxic than free cyanides,  complex cyanide-
bearing wastes are of concern because of their potential to
undergo photodecomposition to form toxic hydrogen cyanide and
free cyanide decomposition by-products.  (See Listing Background
document for Cyanide Wastes, Response to Comments Section,
        This has been retyped from the original document.

Comment No. 3 for more details.)1   Therefore,  if the metal heat
treating process uses cyanides in any form, the process is
covered by the hazardous waste listings.

Dear Mr. Nalewajax

    X an writing in response to your letter of March 20, 1984,
and the resolution of the Weed Science Society of Anerica
requesting the removal of 2,4-D waste from regulation under
the Resource Conservation and Recovery Act (RCRA).

    The toxic properties of 2,4-D were evaluated by the KPA's
Office of Drinking Hater as part of the process leading to
the development of the National Interim Primary Drinking
Water Standards (MIPOWS).  Inclusion of 2,4-D in the list of
toxicants regulated under 40 CFR 261.24 and 261.33  of the RCRA
regulations was based on the evaluation that was conducted
in support of the NIPOWS.

     The HIPDMS for 2,4-D was derived assuming that the lowest
long term level with minimal or no effects for the rat and the
dog is 50 and 8 mg/kg/day respectively.  Based on these values,
a "safe level" for man was derived of 1.12 mg/man/day.  (See
National Interim Primary Drinking Water Regulations, BPA-
570/9-76-003, Environmental Protection Agency, Office of Water
Supply),  Verschuaran (Handbook of Environmental Data on
Organic Chemicals, Van Mostrand Reinhold, New York, MY, 1983)
indicates that 2,4-D is significantly toxic to manaais (i.e.,
oral rat LDSO 300*1000 mg/kg, oral mourn LD50 375-521 mg/kg,
oral dog LDSO 100 mg/kg).  In addition, 2,4-D exhibits acutely
toxic effects at the mg/1 level in a variety of aquatic species
which indicates that Its uncontrolled release into the environ-
ment can also affect the ecological balance. . for the above
reasons, 2,4-D and its salts have been listed under the hazardous
waste identification regulations.

Dear Dave:

     As a result of several inquiries, we wish to clarify which
wastes generated by Bell Lumber and Pole, located in New
Brighton, Minnesota, are listed as hazardous under Part 261 of
the hazardous waste regulations implementing the Resource
Conservation and Recovery Act.  At the present time, one category
of wastes from the wood preserving industry is included as a
hazardous waste from a specific source:  K001 "Bottom sediment
sludge from the treatment of wastewaters from wood preserving
processed that use creosote and/or pentachlorophenol".

     From process descriptions compiled by the Minnesota
Pollution Control Agency, the National Institute of Occupational
Safety and Health, and Region V during a recent plant site visit,
the following is my understanding of the current and past waste
generation points at the Bell Lumber and Pole facility.

     1.   Work tank/storage tank sludges.  These sludges
     accumulate at the bottom of vertical storage tanks for
     preservative solutions of pentachlorophenol.  In the past,
     these tanks may have been used for creosote preservative
     solutions.  These tanks receive reclaimed preservative
     solutions, store them, and in some cases heat the reclaimed
     solutions prior to reuse in the wood treating tank.
     Currently, sludges from these tanks are discharged to the
     mechanical oil/water separator described below.

     2.   Mechanical oil/water separator sludges.  Wastewater
     contaminated by oil/preservative solutions and sludges are
     collected at a sump at the wood treating tank and are
        This has been retyped from the original document.

-------
     discharged to a tank (81'  x 6') where oil/water separation
     takes place.  This oil/water separation procedures treats
     effluent generated after completion of the wood treating
     process.  Although no water is intentionally added to this
     process, a substantial amount of water is released from the
     wood itself during hot oil/preservative solution steeping.
     Some of this wastewater is emitted to the air as steam
     during the steeping process, and some is entrained in the
     preservative solution or settles to the bottom of the wood
     treating tank.

          The first mechanical oil/water separation device was
     installed in 1976 at "Tank 8".  A steel belt oil/water
     separator, installed in 1980, is in current use and operated
     daily except when the weather is cold enough to freeze the
     water.  This oil/water separator daily receives contaminated
     wastewater effluent directly from the treating tank.
     Approximately one time each year, bottoms from the
     storage/work tanks are also added to the mechanical
     oil/water separator.

     3.   Thermal dehydration/evaporation sludges.  The
     oil/preservative solutions recovered by the mechanical
     oil/water separator undergo a secondary wastewater treatment
     step by thermal dehydration/evaporation.  This is currently
     conducted in the "Butt Treatment Tank" with heating coils,
     generating a sludge.  Other sludges may be added directly to
     this thermal dehydrator/evaporator without first being
     subjected to mechanical oil/water separation.  Thermal
     dehydration or evaporation of wastewater from wood
     preserving solutions typically generates a sludge.

     Before installation of the mechanical oil/water separation
     devices, a thermal dehydration treatment was used as the
     sole procedure for drying oil/preservative solutions from
     the wood treating tank.  Fuel oil, used as the solvent for
     either creosote or pentachlorophenol, typically will entrain
     significant amounts of water during the wood treating
     process.  Entrained wastewater must be removed to regenerate
     dry oil/preservative solutions for good penetration into the
     wood during the treating process.  Thermal dehydration of
     the used oil/preservative solutions in the past could be
     assumed based on typical industrial process information,
     with concomitant sludge generation.

     From the above description of sludge generating processes,
the mechanical oil/water separator sludges and the thermal
dehydrator sludges meet the K001 listing description of
wastewater treatment sludges from wood preserving processes using
creosote and/or pentachlorophenol.  If the storage tank/work tank
sludges are mixed with the mechanical oil/water separator sludges
or thermal dehydration/evaporation sludges, then the resulting
mixture also must be managed as a K001 hazardous waste.
        This has been retyped from the original document.

-------
     Page 21 of the Listing Background Document for the Wood
Preserving Industry states "wastewater treatment sludges are
generated first at oil/water primary separation", which includes
any mechanical oil/water separation device as described for the
Bell Lumber and Pole facility, as well as sludges from surge
tanks, drainage pits, etc.  On page 21, dehydration of
oil/preservative solutions and on page 26, evaporation of
wastewater from the addition of heat are also described as
wastewater treatment processes generating sludges defined as K001
hazardous wastes.

     Based on processing procedures used by the wood preserving
industry, it is reasonable to assume in the absence of proof to
the contrary that Bell Lumber and Pole was generating a K001
wastewater treatment sludge prior to 1976, and indeed throughout
its manufacturing history.  This is because water removal from
spent wood treating solutions is necessary to regenerate usable
oil/preservative solutions.  We do not know if thermal
oil/preservative dehydration or another procedure was used.

     Further indication that K001 wastewater treatment sludges
were generated prior to installation of the mechanical oil/water
separation devices in 1976 and throughout the facility's history
comes from the CERCLA "Notification of Hazardous Waste Site",
date June 9, 1981.  Thomas E. Doten, then Vice President and
Plant Manger of Bell Lumber and Pole, states that K001 waste was
placed in the on-site landfill up until the late 1960's.  He was
unable to estimate the amount of K001 waste deposited in this
landfill "given age [circa 1920] of facility".

     Generation rates of K001 wastewater treatment sludges may be
estimated by information in the Listing Background Document and
the Effluent Guidelines Division Data Collection Portfolio.  From
the Listing Background Document, the amount of pentachlorophenol
treated wood and the amount of pentachlorophenol wastewater
treatment sludges generated annually yields an estimate of 0.276
cubic feet of sludge per 1000 cubic feet of treated wood.
Effluent Guidelines Division data for all types wood treating
processes (creosote, pentachlorophenol), indicates that
approximately 0.432 cubic feet of sludge is generated per 1000
cubic feet of treated wood from zero wastewater discharge plants.

     An average wood preserving plant treats 4000 cubic feet of
wood per day.  Therefore, the annual wastewater treatment sludge
generated by a plant would be in the range of 55-87 drums.  Some
individual plants have indicated they produce several times as
much wastewater treatment sludge.  If sludges from other plant
sources such as storage or work tanks are mixed with the
wastewater treatment sludges before or after oil/water separation
procedures,  then this volume estimate would be higher.

     I hope this information is useful in evaluating the waste
sources of groundwater contamination from the landfill on the

Dear Mr. Yanceyt

     This is to confirm our Hay 29, 1984 telephone conversation
regarding your letter to Alan Corson dated Nay 17, 1586 f regarding
ballast fluid classification.  Z hope this discussion clarifies
your question on the formaldehyde.

     Formaldehyde is listed (as U122) in 40 CPR 261.S3(f).  This
listing refers only to discarded commercial chemical products,
off-specification species, container residues, and spi>.l residues
having the generic name "formaldehyde." The comment in Section
261.33(d) explains that the tern "commercial chenical product*
refers to a substance Manufactured for commercial us® «hich is
commercially pure or a technical grade and formulations in which
the chemical is the sole active ingredient.  It does $>€»£ refer
to a material, such as a process waste, that contains essy of the
substances listed in 261.33(e) or 261.33(f).  To be 6G*s*£dered
a hazardous waste, such process wastes will be listed £n either
Sections 261.31 or 261.32 or be identified as a hamardous waste
by characteristics as set forth in the regulations.

   In other words, formaldehyde (and sodium pentachlorophenate)
is being used to keep down growth in the ballast fluid.  The fluid
is not considered to be the commercial chemical product formaldehyde.
Ship ballast fluid would have to be specifically listed as a hazardous
waste stream or be hasardous on the basis of the characteristics
(ignitability, corrosivity, reactivity, or EP toxicity), as explained
above*

Dear Mr. Holyoak i

     I mm  writing  in response to your Hay 15, 1984, request
for clarification of  the existing Resource  Conservation and
Recovery Act (RCRA)  hazardous waste identification regulation*
as they apply  to  deodorants  for  portable toilets as well as
potential additional requirements due to pending
     Chemical deodorants  containing  snail  amounts o£ formal-
dehyde are  used to provide  sanitary conditions  in portable
toilet units.   Let me  explain how  the current  Mutilations
apply to  formaldehyde.   Formaldehyde  is  a  hazardous  wast®
if it  is  a  discarded   commercial  chemical  product.    The
comment in 40 CPR 261.33(4) explains that the term eownereial
chemical product refers to substances manufactured for commer-
cial use which  are  commercially  pure  or  a technics?,  grade
and formulations  in which  the chemical is  the  sole  active
ingredient.  Zt does  not  refer  to all materials containing
any amount of formaldehyde*

     In other words, the  formaldehyde  is not the sole active
ingredient of  the deodorant  and  is  therefore  not  a  listed
hazardous waste stream.   The deodorant would only be a hazardous
waste if it exhibited any of  the  characteristics defined in
the regulations (igni table, corrosive, reactive, or BP toxic,
as outlined  in  Sections 261.21,  261.22, 261.23, and 261.24).

generated from both their operations meet the description of         _
EPA Hazardous Waste Mo.  FOO6.   More specifically, tfc* SPA            v-.
Background Document defines phosphating  as a component of            2
electroplating of chemical conversion*coating.  Otfecir components     o
of this category include coloring, chromating, and iiamersion         o
plating.  Accordingly, wastes generated  from the pftosphating         *°
operation at Gulf and Western would be considered n&x&rdous
wastes.

     With respect to their other operation, wastewatsr treatment
sludges generated from sine plating operations on carbon
steel are not considered hazardous wastes when the waste
stream froa these operations is maintained and treated separately
(segregated) from other waste stream generated at the facility.
However', Gulf and Western's zinc plating line also includes
a chroma te passive ting bath in  which the low carbon steel
stampings are dipped after plating.  Chrome passivating is
considered a component of chemical conversion coating and
therefore the wastewater treatment sludges generated from
this operation would also  be considered  hazardous.

     Therefore,  wastewater treatment sludges generated by
both operations  at Gulf  and Western are  considered EPA
Hazardous Waste  No. P006 and subject to  regulation under 40
CPR 262-266.  If you have  further questions regarding this
matter, please do not hesitate  to call Mr. William Sproat of
my staff at FTS  382-4783.

     Pirst, you requested clarification of the listings icOQi and
P006 aa to the scope of their coverage.  These listings include
any sludges derived from the treatment of waatewatera regardless
of where the sludges are formed.  Thus, if a sludge is formed in
a wastewater treatment tank, filtration device, or surface impoundment,
it is K001 or P006 sludge.  These wastewater treatment unita
would be subject to all hazardous waste regulations, including
appropriate permitting standards.*
   There is an exceptions  tanks that treat or store hazardous
   waatewaters are exempt from the part 264 and 265 management
   standards when the tank is part of a wastewater treatment unit

fron  theae tvo tanks would, therefore, be subject to regulation
only  if they meet one or nore of the characteristics of a hazardous
waste, as set  forth in §$261,21-261.24.

      This facility next uses a sand filtration surface impoundaent
(*C*)  to  treat the wastewater effluent after oil/water separation
and flocculation.  The sand filter consists of two 20 x 20 x IS
ft. surface impoundments, with natural clay bottoms, and aides
constructed of preserved wood.  The wastewater is added to the top
of these  units and collected as an effluent froa the bottom, and
sent  to a holding pond (*D*) where additional wastewater treatment
sludges are generated.  Both the sand filter and the holding pond
would be  subject to all hazardous waste regulations and permitting
standards since they are surface impoundments used to manage a
hazardous waste (i.e., the sludge).

      The  principal regulatory question presented by this sand
 filtration unit is whether .the wastewater  that paases  through  the
unit  loses its status as *wastewater* and  becomes  •leachate" because
 it  percolates through the  listed sludge that has been  trapped  in
 the unit,  we do not believe  that the passage of a contaainated
 liquid (e.g., leachate, wastewater)  through a  filter  should  cause
 us  to redefine what  that liquid is,  even  though  the filter may chanye
 the chemical makeup  of the contaminated liquid.  For  purposes  of our

-------
regulatory definitions, what comes out of a filter is the »t
thing that goes  into the .filter,  a, wastewater that .passes  through
a filter in a treatment system .is still a wastewater.  That result
is not changed by the fact that the filter happena to be a  sand bed
and the wastewater emerges from the bottom rather than the  top oC
the treatment unit.*

     The final step in the wastewater treatment system used by the
wood preserving  facility in question is a spray irrigation  field
{*!*).  We are currently investigating the status of this unit to
determine if it  meets the definition of a land treatment unit, a
surface impoundment, or a landfill.  We expect to get back,  to you
on this point in the near future.


     The above discussion regarding waatewater treatment units,
wastewaters, and the storage or disposal of hasardous wastewater
treatment sludges wastes is also applicable to other facilities
generating similar wastes.
    It  should be noted  that this approach  also prevents an operator from
    placing a sand filter  at the bottom of a landfill and then arguing
    that  the liquid emerging from the  bottom of the unit is no longer
    a leachate.  l*aehate  emerging from waste in a landfill remains
    a leachate even after  it has passed through a filter.

MEMORANDUM
Subject:  Clarification of K062 - Spent Pickle Liquor Listing
                                     \ t  ,t
From:     John H. Skinner, Director  Vv^nl
          Office of Solid Waste     M

To:       Directors, Waste ManagemenVoivisions
          EPA Regions I-X.


     Within the past year/ several EPA Regional Offices have
requested clarification of EPA Hazardous Waste Ho, KQ62 *
Spent pickle liquor from steel finishing operations.  This
interpretive memorandum addresses several question and issues
which have been raised regarding the listing.


1) Which operations/processes are considered "steel finishing
   operations" and thus are covered by the listing?

        The Office of Solid Waste (OSW) defines "steel finishing
        operations" as processes which impart desired mechanical
        and surface characteristics to steel.  The following
        processes are included in this description and are
        intended to be covered by the K062 listing, provided
        that spent pickle liquor is generated:

          1) acid pickling
          2) alkaline cleaning
          3) cold reduction
          4) blast cleaning
          5) cold drawing
          6) cold rolling
          7) galvanizing
          8) coating with organic and inorganic compounds

-------
                             -2-
          9) tempering                   I/
         10) coating of steel with metals"
         11) tin plating
         12) electropolishing

     Although the background document for K062 addresses"only
spent pickle liquor from the iron and steel industry, the
Agency intended the listing to cover all industries engaged
in the pickling of steel.  Indeed, many persons who generate
spent pickle assumed that the listing was much broader then
indicated in the background document.2/  Furthermore, on
January 4, 1984, (see Notice of Availability of Data and
Request for Comments, 49 FR 427) the Agency stated that steel
finishing is practiced by a diverse group of manufacturers.
The large number of notifiers indicate that generators in
many industry categories are aware of this interpretation.

     Recently, representatives from the porcelain industry
informally challenged OSW on its interpretation of the K062
listing.  It is their position that the listing pertains
only to the iron and steel industry.3/  However, for reasons
stated earlier, to the extent that facilities within this
industry category pickle steel prior to coating or enameling,
the spent pickle liquor (or any waste derived therefrom) is
considered the listed waste.

     The Agency'realizes that concentrations of the hazardous
constituents of concern for which spent pickle liquor was
listed may differ among industries based on process variations;
however, wastes that do not meet the criteria for which pickle
liquor was originally listed may be excluded from regulation
on a site-specific basis (delisting pursuant to 40 CFR 260.20
and 260.22).  The Agency also will consider industry-wide
petitions to delist these wastes.
I/  Although  coating  of  steel with metal  (electroplating) is
~   considered  "steel finishing,* the Agency did not  intend
    the  K062  listing  to  include electroplating  processes that
    generate  spent pickle  liquor.  This would be duplicative
    since  electroplating wastes are specifically covered
    under  F006.

2/  Data from the RCRA Notification data  base indicate  that
"~   a diverse group of industry categories pickle  steel and
    generate  spent pickle  liquor  (e .g., metal working machinery
    and  equipment; refrigeration  and service industry machinery;
    coating,  engraving and allied services; sanitary  services;
    aircraft  and parts,  and others).

3/  Approximately half the facilities within the porcelain
~"   industry  have notified that they generate either  K062 or
    the  lime  stabilized  waste pickle  liquor sludge.

-------
                             -3-

     At this time, the Agency has taken action on a rulemaking
petition submitted by the American Iron and Steel Institute
(AISI) to remove lime stabilized waste pickle liquor sludge
(LSWPLS) (formerly referred to as lime neutralized waste
pickle liquor sludge) from the presumption of hazardousness
contained in the regulations.  This exclusion however, ipplies
only to LSWpLS that is generated by the iron and steel industry
(SIC Codes 331 and 332).  (See 49 FR 23284 - 23285, June 5,
1984 for specific details regarding the conditions of the
exclusion).

2)  Many electroplating operations pickle prior to electroplating.
    Is the waste generated from this process considered F006,
    K062, D002, or both F006 and K062?

             In considering petitions to delist electroplating
        waste, the Agency has stated that the F006 listing
        includes the acidic wastes (i „_ e., spent pickle liquor)
        from the electroplating process.  Electroplating
        operations typically pretreat the metal using acidic
        baths prdor to electroplating.  The acidic wastes
        from this process are generally mixed with spent
        plating bath solutions and lime treated.  Sludge
        generated from this process is considered F006.  For
        example, an electroplater acid pickles metal parts
        as part of the electroplating process.  The resultant
        wastewater (including spent pickle liquor and rinsewater)
        is neutralized with lime.  Sludge generated from
        this process is F006.  In another example, a galvanizer
        also pickles metal parts prior to galvanizing.  Since
        galvanizing is not included under the electroplating
        category, spent pickle liquor from this process
        would be considered EPA Hazardous Waste K062.   If
        the pickle liquor is lime treated prior to disposal,
        the sludge from this process is a hazardous waste  by
        virtue of the "residue rule* ($261.3(c>(2)).

             In cases where acidic wastes from  the electroplating
        operation remain untreated or are segregated  from
        other process waste and treated  separately, the waste
        is then considered K062  (or lime stabilized waste
        pickle  liquor sludge).

3)  Does the K062  listing pertain  to spent pickling  acids
    other  than those  listed in  the background document for
    K062 (i.e./  H2SO4, HCL, and HNO3 + HF)7

              In developing the background  document for K062,
          the Agency  listed the most commonly used pickling
          agents.  However, we  intended  the  listing to include
          all  acids used in the pickling of  steel.

-------
                             -4-

     I trust that this memorandum adequately clarifies the
K062 listing.  Should you have questions, or require
additional information, please call Jacqueline Sales at

Dear Mr. Gray:

     This letter responds to your recent inquiry regarding the
regulatory status of spent acid from electropolishing of
stainless steel (i.e.,  whether the waste is considered EPA
Hazardous Waste No. K062—Spent pickle liquor from steel
finishing operations).

     As you stated in an earlier conversation with Jacqui Sales,
of my staff, electropolishing is a process which utilizes a
mixture of sulfuric and phosphoric acids (pH 1.0)  to impart a
shiny finish to stainless steel.  As Ms. Sales explained, the
spent pickle liquor listing was intended to include those
processes where acid is used to impart a desired surface
characteristic to steel or steel products; in particular, to
remove oxide scale.  Although the background document for the
listing addresses only the commonly used pickling acids  (i.e.,
hydrochloric, sulfuric, nitric, and hydrofluoric),  the Agency
intended the listing to include all acids used in the
pickling/cleaning of steel.  Thus, spent acid from
electropolishing is considered the listed waste.

     I trust that this letter adequately addresses your concerns.
Should you have additional questions or require further
information, please call Jacqui Sales at (202) 382-4770.

                                   Sincerely,
                                   Matthew Straus

SUBJECT:  Dragout  from EPA Hazardous Wastes No. F007 - Spent Cyanide Plating
          Bath Solutions  from Electroplating Operations  (Except for Precious
          Metals Electroplating Spent Cyanide Plating Bath Solutions)

PROM:     Matthew  A. Straus, Acting Chief
          Waste Identification Branch  (WH-562B)

TO:       James H.  Scarbrough, Chief
          Residuals Management Branch
          Air & Waste Management Division
      This is written in response to your inquiry concerning dragout from
plating bath solutions listed as EPA Hazardous Waste No.  F007.   Briefly, the
process described at Georgia Tubing involves the transfer of parts from a
plating bath solution to a chlorination tank to stop the plating process.
During this transfer, dragout drips off the plated parts, is collected and
transferred to the chlorination tank for treatment.

      In general, your interpretation that the chlorination tank receives and
treats a listed hazardous waste and is therefore a hazardous waste treatment
tank is correct.  However, it should be pointed out that the definition of EPA
Hazardous Waste No. F007 refers to spent, plating bath solutions only.
Therefore, the plating bath solution itself would not be considered an F007
waste until it is spent.  Only the dragout from the plating operation or if
the plating bath solution itself was dumped would be considered an F007 waste
because at that point in the operation it would be considered spent.  In
addition, any sludge that forms in the bottom of the chlorination tank would
also be considered an F007 waste.  The sludge would be considered an F006
waste only if wastewaters from the electroplating operation were to enter the
chlorination tank for treatment in addition to the F007 waste.   If you have
any further questions on this matter, please do not hesitate to call Mr.
William Sproat of my staff at FTS 382-4783.

               LISTING OF BAGHOUSE DUST GENERATED FROM REMELTING
                          OF PRIMARY PRODUCTION STEEL
1.    A facility generates a baghouse dust from remelting primary produced
      steel.  The remelting occurs in electric furnaces.  The baghouse dust
      contains fluoride neutralized by calcium carbonate and the heavy metals:
      lead and selenium.  The baghouse dust has been analyzed for the heavy
      metals (50.65ppm lead and 13ppm selenium).  The analytical methods used
      were 8.56 and 8.59, respectively, in SW-846 (not the E.P. toxicity
      teat).  Assuming that the baghouse dust will fail the EP toxicity test,
      should the waste be K061  (even though it is not primary smelting) or
      should it be D008 and D010?

          The waste generated from this process is K061.   Although steel is
          being remelted,  this process is considered primary production for
          the purposes of RCRA.

RCRA/SUPERFUND HOTLINE MONTHLY SUMMARY                            9444.1985(01}

FEBRUARY 85


      The New York State Health Department deemed a house unfit for
      habitation due to excessive chlordane levels in the soil around  the
      house.  The soil contaminated with chlordane was removed and placed  in
      55-gallon drums. The removal resulted in 45 drums of contaminated  soil
      withan average concentration of 50 ppm.  Is this contaminated soil a
      RCRA hazardous waste?

            The contaminated soil is not a RCRA listed hazardous  waste.
            Chlordane could only be considered a RCRA hazardous waste  if it
            was discarded prior to use or was a container or spill residue.
            If chlordane met any one of these criteria,  it would  be a  listed
            hazardous waste (U036), as listed and described in 40 CFR
            261.33.  In this situation,  however,  none of these criteria were
            met because chlordane was applied as a commercial chemical
            product.  The generator must still determine if the contaminated
            soil exhibits any of the four RCRA characteristics {EP toxic,
            ignitable, corrosive,  reactive).   If the soil does not exhibit a
            characteristic, then it is neither a listed nor a characteristic
            hazardous waste.   Although the contaminated soil is not a RCRA
            hazardous waste (assuming it does not meet a characteristic), the
            generator must be cognizant  of potential liability under CERCLA
            if the waste is not managed  properly.

Mr. Walter G. Talarek
American Wood Preservers Institute
1945 Gallows Road
Vienna, Virginia  22180

Dear Mr. Talarek:

      This letter is in response to your letter dated February 14, 1985 in
which you request clarification of the dioxin listing.  In particular, you
asked for comment regarding the applicability of the RCRA dioxin listings
published in the Federal Register on January 14, 1985 to wastes from wood
preserving processes using pentachlorophenol.

      As you state in your letter, the following hazardous waste listings
relating to pentachlorophenol were promulgated on January 14, 1985:

          F021:   Wastes (except  wastewater  and  spent  carbon  from hydrogen
          chloride purification)  from the production  or  manufacturing use  (as
          a reactant,  chemical  intermediate,  or component  in a formulating
          process)  of  pentachlorophenol,  or of  intermediates used to produce
          its derivatives                                                    (H)

          F027:   Discarded unused formulations  containing  tri-,  tetra-,  or
          pentachlorophenol or discarded  unused formulations containing
          compounds derived from these chlorophenols...                      (H)

          F028:   Residues  resulting  from  the  incineration  or thermal treatment
          of soil  contaminated with  EPA Hazardous Waste  Nos.  F020,  F021, F022,
          F023,  F026,  and  F027                                               (T)

      [Please note that, contrary to the statement in your letter, the latter
      is a "T" not "H" waste].

      Most of these wastes are not typically generated by the wood preserving
      industry.  We, therefore,  generally agree with your assessment that the
      final dioxin rule (published on January 14,  1985)  does not include
      wastes by the wood preserving industry.  However,  wood treatment
      facilities could be covered under the listing if:

             A wood preserving facility makes a derivative of
             pentachlorophenol  (e.g.. a sodium or potassium salt); the wastes
             resulting from such a process would be EPA Hazardous waste F021.

             A wood preserving facility makes formulations containing tri-,
             tetra-, or pentachlorophenol or its derivates; waste resulting
             from such a process would be F021 wastes.

             A wood preserving facility discards unused formulations
             containing tri-, tetra-, or pentachlorophenol or its
             derivatives; these would be EPA hazardous waste No. F027.

      Furthermore, although most of the wastes generated by the wood
preserving industry are probably not regulated by the January 14, rulemaking,
you are aware that we are presently investigating whether wastes resulting
from wood preserving processes using pentachlorophenol should be listed as
hazardous (or acute hazardous)  wastes, and whether CDDs and CDFs should be
added as constituents of concern in the wood preservation process waste

already listed [EPA Hazardous waste K001].  As previously stated, we will take
appropriate regulatory action if warranted.

letter.  Please do not hesitate to call Matt Straus, if you have further
questions concerning this matter,  Mr. Straus can be reached at (202) 475-

 Register (45 FR 33122), §261.30(b)  says that Appendix  VXX             T
 identifies the constituent which caused EPA to  list the  waste  in      ™
 §261.31 or §261.32 as IP toxic or toxic waste.   In  Appendix YXX*      x
 only the listed solvents are specified.  The spent  solvent             2.
 listings in §261.31 are worded "The following spent halogenated/      £
 non-halogenated solvents..." which clearly designates  only the
 listed solvents.                                                      s

      Moreover, currently, only solvents used separately  are
 covered by the FOO1-005 listings.  The Agency issued & letter  on
 July 21, 1981, to the Safety-Kleen Corporation  that s%«£ed that
 the §261.31 listings only refer to "...spent solvents  identifiable
 as any technical grade of the chemical that is  produced  or marketed
,and not to mixtures otherwise containing the chemical o*   (A copy
 of RIL 95 is enclosed.)  As you observed, this  interpretation
 is consistent with the approach taken  in identifying 9261.33
 hasardous waste.

      Zf individually used solvent waste streams are mixed after
 generation, the mixture is a mixture of F-listed waste streams.
 You can see how important it is to be  able to identify the
 original source of the wastes in order to classify  the mixture.
 Just knowing the composition of the waste is not enough  to
 know what waste code(s) to apply to the waste.   Regulations
 under development will identify spent  solvents  on the  basis of
 total solvent contained in the mixture.

      Finally, States with authorised programs may have more
 stringent or extensive regulations than EPA or  operate a progran
 with greater scope of coverage than EPA according to §§271.Hi)
 and 271.121(1).  Zf States designate mixtures of solvents used

Dear Mr. Bassellt

     I am glad to clarify  the  issue that you raised in your
letter of April 1, 1985.   The  identification of RCRA "P*
"U" wastes (chemical products  that are hazardous wastes
discarded) is not as obvious as the identification of other
listed wastes.

     As you know, 40 CPR 262.11 outlines the generator's
responsibility for identifying hazardous waste as followsi
first, check to see if the waste  is excluded from regulation
under Part 261 Subpart D,  second, see if the waste is listed in
Part 261 Subpart D, third  (if  it  is not a listed waste),
determine whether it is a  characteristic waste by testing or
applying knowledge of the  process producing the waste.  Neither
tne fish nor the used formalin would qualify as a listed RCR&,
waste.

     To clarify why the fish and  the used formaldehyde are not
listed waste, the reasoning is as follows*  Formaldehyde is
listed (as U122) in 40 CPR 261.33(£).  This listing refers
only to discarded commercial chemical products, off-specification
species, container residues, and  spill residues having the
generic name "formaldehyde."   The comment in S261.33(d)
explains that the term "commercial chemical product" refers
to a substance manufactured for commercial use which is
commercially pure or a technical  grade and formulations in
which the chemical is the  sole active ingredient*  It does
not refer to a material, such  as  a process waste, that contains
any of the substances listed in $261.33(e) or $261.33(f).  To be
considered a hazardous waste,  such process wastes will be
listed in either §$261.31  or 261.32 or be identified
as a hazardous waste by characteristics, as set forth in the
regulations.

-------
     The comment excludes waste materials that contain any "P"
and "U" suostances unless the vaste stream is listed (i.e.,
listing formaldehyde used as a preservative) or the waste meets a
Part 261 Subpart C criteria.  This means EPA regulates unused
cnemicals but not all wastes containing the same chemicals.
There are regulatory efforts underway that may eliminate this
discrepancy.

     Of course* the generator also needs to determine that
the discarded fish and formaldehyde are not hazardous on the
basis of exhibiting any of the characteristics of hazardous
waste.  It is unlikely that the formalin will be found to be
ignitable* corrosive, reactive, or SP toxic.  If you hava- any
other questions on the Federal policy of regulatory hazardous
waste* feel free to contact me at (202) 382-4770.  Of course*
you need to comply with the New York Department of Environmental
Conservation determination in the State of New York* since the
State program is operating in lieu of the- Federal program.

                                Sincerely yours,

       Per your request the following paragraph is the RCRA response
to the embalming fluid question in the subject inquiry.

          The RCRA hazardous waste identification regulations
     contain two mechanisms for identifying a waste as a
     hazardous waste, lists and characteristics.  A waste is
     a hazardous waste if it either is listed (40 CFR 261*31,
     32, or 33) or it exhibits one or more of the defined
     characteristics (§261.21, 22, 23, or 24).  While used
     embalming flui'ds do not qualify as hazardous under sny
     of these criteria, many people mistakenly believe th?»y
     they do because formaldehyde, the key ingredient in
     such products, is listed under §261.33.  Section 2fe3c33
     lists commercial chemical products which are hazardous
     wastes when discarded or intended to be discarded.  It
     does not include wastes which result from the intended
     use of the product.  Thujs, embalming fluid, since it-
     consists of formaldehyde plus some inert ingredients
     (e.g., colorants and perfumes), would be a hazardous
     waste if discarded unused and the septic tank/tile
     field could classify as a Class 4 well.  However, if
     the generator is disposing of embalming fluid which has
     been used, for example, to flush body fluids out of the
     cadaver, then disposal of the fluid does not constitute
     disposal of a hazardous waste and the tank/field is not
     a Class 4 well.

Mobay Chemical Corporation

P.O. Box 4913

Dear Mr. Scott:

     I am writing  in response to your request for a decision
regarding whether  certain wastes associated with the manufacture
of pesticides at your Kansas City, Missouri plant are considered
to be listed hazardous wastes.  More specifically, you have
inquired whether the manufacturing processes for prothiophos,
sulprofos, fensulfothian, and MTMC generate listed spent .solvents.
These manufacturing processes use either toluene, methanol, or
m-cresol as reactants in such excess that large amounts of these
materials do not react and are removed from the process as a waste
stream.  Steve Hirsch from the Office of General Council and I
have carefully reviewed the material which you have submitted as
well as the Background Listing Document (BLD) and the Federal
Register notice for the listing concerning wastes from the usage of
organic solvents.  Based on our review, we conclude that the wastes
that contain the unreacted materials are not listed spent'solvents.

     We agree with Mobay's assertion that the original solvent
listing was not intended to include chemicals which are commonly
used as solvents when they are used as reactants.  As the bases for
our decision, we cite the following excerpts and quotations from the
BLD and the Federal Register notice:

     o The footnote on page 33 of the BLD states, "Large amounts
       of chemicals listed in Table II-l are used in such non-
       solvent applications as chemical feedstock..."  Thus, usage
       as a feedstock was considered to be a non-solvent use.

     o Pages 40 and 41 of the BLD define solvent application in the
       production  of pesticides to include "... usage as a reaction
       (synthesis) medium, and usage in equipment cleaning."  The
       term "reaction medium" does not mean reactant or feedstock;
       rather, it  refers to a substance that is capable of dissolving
       another substance (i.e., solute) to form a uniformly dispersed
       mixture or  solution thereby enhancing the ability of the
       solute to undergo a chemical reaction with other soluble
       substances.

-------
                              — 2—
     o The language in 40 FR 56584 (November 17, 1981) clearly
       states that substances commonly used as solvents, "... may
       also be used in a manufacturing process as chemical reactants
       or process intermediates and, when so used, are not considered
       to be spent solvents."


     It should be noted that although we do not consider the subject
waste streams to be listed hazardous wastes, these streams may
exhibit hazardous characteristics (e.g., ignitability).  If such is
the case, these wastes should be handled under the waste management
standards contained in 40 CPR Parts 262-266, Part 124, and the
permitting requirements of Parts 270 and 271.  If you have any
questions regarding our decision on this matter, you may contact
me at (202) 382-4761.
                                Sincerely,

     This memorandum responds to your inquiry of April 29, 1985,
requesting concurrence on the status of toluene-laden filter
residue generated from the ink production process at Onion Camp
Corporation.  Your memorandum states that both EPA Region IV and
Georgia EPO consider the waste to be a spent ~ sol vent— EPA Hazardous
Waste No. POOS.  We disagree with this determination.

     In general, chemicals which are used as solvents are not
consumed, nor are they physically or chemically altered during
the process.  When used in this manner, that is, for their
"solvent" properties, wastes generated are considered spent
solvents when they consist of solvents (&nd other materials)
which no longer meet the specifications £OE which they
originally used and are intended for discard or further
     The filtering unit at Union Camp is an integral part of
the production process, since its primary function is removal
of unreacted chemicals, excess reactants and other impurities
from the product.  The filtration cake generated at this unit,
however, is not a spent solvent.  The waste stream apparently
only includes the solvent as a contaminant.  As noted in Union
Camp's letter to John D. Taylor of the Georgia Environmental
Protection Division, "the filter cake waste stream consists
primarily of filter aid, unreacted metal oxides, and resinate
product."  Tli« listing background document notes,

          th« wastes encompassed by this listing do not
     include waste streams where solvent is a contaminant,
     such that the waste stream is not spent solvent, as
     defined above.  Thus* wastes which contain as consti-
     tuents solvents which are used in the industrial
     process are not included within the scope of this

Solid Waste Determination

4.  A warehouse stores product acrylonitrilc.  An accidental fire destroys the ware-
    house and produces an ash from the burned acrylonitrile.  The acrylonitrile
    was not a hazardous waste prior to the fire.  Is the ash viewed as solid waste
    generated from the disposal of a hazardous waste per §261.3(c) (2) (i) and therefore
    a listed hazardous waste per §261.3(c)(2)(i)?

         The ash from an acrylonitrile warehouse fire is regulated as U009 hazardous
         waste.   Burned product is viewed as disc-anted.  Thus, the acrylonitrile is
         a solid waste per §261.2(b)(l) and §261.2(b) (50 FR 614, January 4,  1985).
         Ash from the acrylonitrile is a list.ad hazardous waste per §261.3(c)(2)(i).

the surface impoundment at the Rockwell International, Newark,
Ohio facility is considered a hazardous waste impoundment, listed
as EPA Hazardous Waste No. F006.

     It is my understanding that. Rockwell International manufactures
automotive gears.  These gears are placed in an iron/Eianaanese/
phosphate tank to provide lubrication.  The gears are them dipped
in a rinse tank, and this contaminated rinse water enters the
impoundment.  The F006 listing applies to wastewater treatment
sludges from electroplating operations.  Any sludge thet. orecipitates
out of Rockwell International's wastewater is classified as hazar-
dous.

     Rockwell International's lubrication coating process is con-
sidered electroplating, as defined in the listing background
document.  A number of production processes, including coating,
are considered subcategories of the electroplating industry.
Electroplating is defined as the application of a surface coating,
usually, but not always, by electrodeposition to provide corrosion
protection, erosion resistance, anti-frictional characteristics
or decoration.  In particular, phosphate conversion coating pro-
duces a layer of insoluble crystalline phosphate on the surface
of a metal that provides a base for lubricants.1

     Consequently, Rockwell International's iron/manganese/phosphate
lubricating process is considered electroplating, and sludge that
results from treatment of the wastewater is considered hazardous

Dear Mr. Johnson:

     We have reviewed your letter of July 22, 1985, notifying the
Environmental Protection Agency (EPA) of your intent to dispose
of over 20,000 gallons of rinsates generated as a result of
cleaning containers that contained 2,4,5-T and other pesticide
formulations by deep well injection.  These waste rinsates are
listed as acute hazardous wastes under EPA regulations (see
enclosed Federal Register notice)  and subject to all regulatory
provisions of the Resource Conservation and Recovery Act.  Thus,
the waste rinsates can be disposed only at a deep well facility
which is permitted to handle dioxin-containing wastes.  If the
facility at which you intend to dispose the waste rinsates is
permitted to handle such wastes, you may proceed with the
disposal plan.  However, if the facility is not permitted you can
either seek a facility that is permitted to handle these wastes
or petition the Agency to exclude your wastes from the hazardous
waste list.

     While wastes described in the regulations generally are
hazardous, a specific waste meeting the listing description from
an individual facility may not be.  For this reason, 40 CFR
260.20 and 260.22 provide generators the opportunity to petition
the Administrator to exclude a waste on a site-specific basis
from the hazardous waste list.

     To be excluded, petitioners must show that a waste generated
at their facility does not meet any of the criteria under which
the waste was listed.   (See 40 CFR 260.22(c).)  In addition, the
Agency is required to consider factors (including other
constituents) other than those for which the waste was listed if
there is a reasonable basis to believe that such additional
factors could cause the waste to be hazardous.  Accordingly, a
petitioner must demonstrate that his waste does not exhibit any
of the hazardous waste characteristics and present sufficient
information for the Agency to determine whether the waste
contains any other toxicants at hazardous levels.
             This has been retyped from the orioinal document.

-------
     If you wish to del1st the subject waste rinsates  from the
hazardous waste list, you can petition EPA to exclude  the
rinsates from the listing under CFR Part 261.  The  petition must
include sufficient information for the Agency to determine
whether the waste meets the criteria for which it was  listed as
well as information to determine if any other hazardous
constituents are present in the waste rinsates at levels of
regulatory concern.  The analysis data included in  your  letter to
EPA can, in part, be used to support a delisting determination
should you decide to petition the Agency for an exclusion to the
listing.

     If you have any questions or need further information on the
delisting procedures, please contact Dr. Howard Fribush,  Office
of Solid Waste, or (202) 475-6726.

                                   Sincerely,

Suite 2250
41 S. High Street
Columbus, Ohio  43215-6199

Dear Mr. Lewis:

     This letter responds to your inquiry of June 14, 1985,
regarding the regulatory status of a solvent mixture  (Nalcast
6015, water and wax) and residue from a water-wall paint spray
booth in which solvent-based paints are sprayed.

     First, you are incorrect  in stating that Nalcast 6015  (used
in the removal of wax)  is considered a process waste when
intended to be discarded.  Since Nalcast 6015 is used as a
"solvent" (i.e., to clean wax  from metal parts) it is considered
"spent solvent" when it has served its intended purpose and can
no longer be used without further processing.  However, you are
correct in stating that under  the current hazardous waste
regulations, spent solvent mixtures are not regulated, unless
they exhibit one or more of the characteristics of hazardous
waste (j._.e. , ignitability, EP  toxicity, reactivity, and
corrosivity).

     At this time, the  spent solvent listings pertain only to the
technical grade or the  pure form of the solvent, thus, solvent
mixtures remain unregulated.   On April 30, 1985, the Agency
proposed to close this  regulatory loophole by expanding the
universe of wastes considered  "spent solvents" to include solvent
mixtures containing ten percent or more of one or more listed
solvents (see enclosed  Federal Register notice).  When this rule
becomes final, Nalcast  6015, when spent or discarded, will be
considered a listed hazardous  waste.  In addition the Nalcast
6015/water/wax mixture  also will be considered hazardous waste
based on the provision  in the  "mixture rule"  (40 CFR
261.3(a)(2)(iii) which  states  that a mixture of solid waste and
hazardous waste is considered  "hazardous waste."

With respect to the water-wall spray booth residue, these wastes
are not hazardous waste unless they exhibit one or more of the
characteristics of hazardous waste.  As you correctly stated,
solvent-based paints are not listed hazardous waste when
discarded nor are they  covered under the spent solvent listings.
The listings do not apply to waste streams where solvents are a
contaminant.

                                          JULY 1985
The Solvent Mixture Rule

4.  EPA published a proposed rule on April 30, 1985, (50 FR 18378}  which would regulate
    certain spent solvent mixtures.  The proposed rule amends $261.31 so that spent solvent
    listings having EPA hazardous waste numbers F001 through F005 would be combined under
    the F001 listing.  More Importantly, the proposed rule would regulate certain spent
    solvent mixtures that are not currently regulated due to the "sole active ingredient"
    interpretation.  * The proposed hazardous waste description for F001 includes "spent
    solvents and spent solvent mixtures/blends containing, in total,  ten percent (or more)
    by volune" of the listed spent solvents.  How will EPA interpret  "ten percent (or
    more)  by volume?"  For example: (a) Does a solvent blend containing trichloroethylene
    and methylene chloride (both listed spent solvents under FOOD, each present at five
    percent by volune, meet the listing description?  (b)  Does one of the spent solvents
    listed under F001 have to be present at ten percent by volume?

        EPA interprets the phrase "ten percent (or more) by volune" to mean the total per-
        centage by volume calculated by sunning the percentages of  all F001 listed spent
        solvents included in a mixture/blend.  "Ten percent (or more)  by volume" does not
        mean that a particular spent solvent under the F001 listing must be present in the
        mixture at ten percent by volume.

        (a)  A solvent mixture/blend containing two F001 listed spent  solvents at five per-
        cent by volume each would be considered a F001 listed hazardous waste.

        (b)  In order for a mixture to meet the spent solvent listing,  a single  solvent need
        not be present at a concentration of ten percent.  Rather,  the ten percent threshold
        refers to the total of all listed solvents in the mixture.

   *Currently the FO01-F005 listings only apply to the spent form of the listed solvents
    where  only one solvent (i.e., sole active ingredient) solvent was  used in a process.
    The F001-F005 listings do not apply to the spent form of solvent blends or mixtures
    with more than one active ingredient (i.e., two or more solvents listed in  $261.31).

Mr. Robert E. Broyles
Purina Mills, Inc.
Checkerboard Square
St. Louis, MO  63164

Dear Mr. Broyles:

     This is in response to your letter of September  6, 1985, and
pursuant to your conversation with Dr. Judy Bellin.   In
particular, you requested that EPA clarify whether persons who
solely blended commercially available materials are exempt from
the dioxin regulations; whether the rinsate from the  equipment so
used is EPA hazardous waste; and whether  EPA  can provide for an
expedited delisting petition.

     Concerning the first point, the dioxin regulations
promulgated on January 14, 1985 provide that  the past
manufacturing operation described in your letter and  discussed
with Dr. Bellin  (i.e.. the formulation of chemicals derived from
2,4,5-trichlorophenol) presently results  in the generation of EPA
Hazardous Waste No. F023.  This applies to the waste  resulting
from the company's mixing and formulating tanks.

     Two courses of action are available  to change this
determination.  The company can replace the mixing tanks, or it
can submit a delisting petition showing that  the waste in
question does not contain chlorinated dioxins or
-dibenzofurans or other toxicants at levels of concern.  Waste
generated after substitution of "new" equipment, or after
delisting of the waste, would no longer be considered EPA
hazardous waste.

     With respect to the evaluation of a  delisting petition, we
cannot guarantee that the petition will be processed
expeditiously.  The Agency already has approximately  300
petitions that are currently being reviewed and acted upon; your
petition would have to be considered in an appropriate order.

     I trust the above adequately responds to your concerns.  If
you have further questions, please call Judy  Bellin at  (202) 382-
4789.

                                   Sincerely,

       Honorable Virginia Smith
       House of Representatives
       Washington, D.C.  20515

       Dear Ms. Smith:

            I have reviewed EPA's classification of spent pickle
       liquor as a hazardous waste as you requested in your
       September 12, 1985,  letter to the Administrator.  However,
       the Agency has taken the position that spent pickle  liquor
       from any source, including hot dip galvanizing, is a listed
       hazardous waste (it  is listed in the regulations as  K062) e
       This interpretation  is consistent with the letter from jack
       McGraw (then Acting  Assistant Administrator for Solid Waste
       and Emergency Response) to Mr. Satterfield on April  10,
       1985.  In that letter, Mr. McGraw stated that hot dip
       galvanizing is excluded from the electroplating category?
       however, no such statement was made with respect to  the
       pickle liquor waste.

            I should point  out, however, that a number of companies,
       especially those in  the porcelain enamel industry, have taken
       exception to this view,  in fact, a law suit was filed bv the
       porcelain Enamel Institute (PEI) disputing the Agency's
       application of the K062 listing beyond the Iron and  steel
       industry.  As a result of this suit and a rulareaking petition
       filed by several members of PEI, the Agency recently requested
       comments on the Agency's application of the KOS2 listing.
       This request for comment appeared in the Federal Register on
       September 10, 1985*   I have included a copy of this  notice
       for your convenience.

            In the notice,  you will find a discussion of the issues
       and background information on the Agency's position.  Since
       the coaswnt period is now open, Mr. Soderquisfc may make any
       comments he believes appropriate about the K062 listing.  I
       can assure you that all comments will be evaluated as part of
       the Agency's rulemaking procedure.

            The delisting mechanism is also an alternative; it need
       not take three to four years.  The time it takes for processing
       a delisting is directly dependent upon our receiving a complete
       delisting petition from the company filing the petition.  We

-------
recently published a guidance document (EPA/530-SW-85-003) to
help petitioners file complete petitions.  This document is
available from the National Technical Information Service.

     I realize that compliance with EPA's regulations may be
costly, however, we believe that the costs are justified in
order to protect our ground-water resources.

     I thank you for your concern in this matter.  If
Mr. Soderquist or you would like any additional information,

Atlanta, Georgia  30329

Dear Mr. Esral:

     This letter is written  in response to your December 16
letter to J. Winston Porter, regarding the Office of Solid
Waste's definition of primary and secondary production of steel
in electric arc furnaces.  As you are aware, the electric arc
furnace is the most versatile of all steelmaking processes
because it can be operated as either an acid or basic, oxidizing
or reducing process and, thus, can accommodate any combination of
raw materials including ore, steel scrap, and pig iron (plus
fluxes such as limestone and fluorspar).  In general, nearly all
steelmakers using the electric arc furnace use a combination of
all of these raw materials.  Therefore, the Agency does not have
a definition for primary and secondary production of steel in
electric arc furnaces and  does not differentiate between the
wastes generated when a specific combination of raw materials are
used.

     The Agency's use of the term, "primary steel production" is
meant to distinguish between manufacturers who produce steel
using the electric arc furnace and foundary operators who use the
electric arc furnace to melt steel scrap for castings.  The
Agency made this distinction clear when it published its response
to a comment received on the interim final rule for the K061
listing (see 45 FR 33124,  May 19, 1989) in which a clarification
on the scope of the listings was requested.  The interim final
rule read, "Emission control dust/sludges from the electric
furnace production of steel."  The commenter indicated that it
was not clear whether the  listing description applied only to
primary steel production or  to both primary steel production and
to foundries using steel scrap in their electric furnace
production.

     The Agency's response was that the listing was intended only
to include wastes from primary steel production and that this
intent is reflected in the listing background document, which
refers throughout to primary steel production.  Also, the Agency
stated that it was uncertain whether foundry electric furnace
emission control dusts and sludges are sufficiently similar in
composition to warrant inclusion in the same listing.
            This has been retyped from the original document.

-------
                               -2-

     In summary, all dusts and sludges from the production of
steel in electric arc furnaces are listed hazardous wastes unless
generated from foundry operations.  In addition, dusts  and
sludges from foundry operations may be hazardous wastes if they
exhibit any of the characteristics of hazardous wastes  as
described in 40 CFR 261, Subpart C.

Dear Mr. Igli:

     Thank you for your  letter of  January 2,  1986, regarding the
disposal status of containers formerly containing pentachloro-
phenol  (PGP) .  In your letter, you request that  I explain how the
January 14, 1985 dioxin  rules deal with the management of these
wastes.

     As you stated in your  letter,  an  emptied, unrinsed container
which formerly contained an unused formulation of PCP is EPA
Hazardous Waste No. F027.   Under the rules promulgated on January
14, 1985, these containers  must be disposed either at a fully
permitted facility having a waste  management  plan for this
("dioxin") waste; at a permitted incinerator  that has
demonstrated 99.9999% destruction  and  removal efficiency (6-9s
DRF) for the chlorinated dioxins  (CDDs)  and -dibenzofurans  (CDFs)
or for the principal organic hazardous constituents  (POHCs) that
are more difficult to destroy than the CDDs/CDFs; or at an
interim status facility  which has  received certification from the
Assistant Administrator  for Solid  Waste and Emergency Response as
satisfying the performance  standards in Subpart  0 of Part 264.
These containers may also be stored at an interim status facility
in compliance in the tank or container standards.

     At present, the residues of such  incineration are considered
to be an EPA acute hazardous waste.  However, on September  12,
1985, the Agency proposed a regulation that would change their
status to hazardous wastes  (rather than acute hazardous wastes),
which could then be managed at interim status land disposal
facilities (see enclosure).
            This has been retyped from the original document.

-------
     At this point  in time,  I am not  aware of any potential rule
change which could  allow these wastes to  be managed any
differently than described above.  Please feel free to call Dr.
Judith Bellin,  if we can be  of any further assistance; her
telephone number is (202) 475-8551.

                                   Sincerely,

Dear Mr. Warren:

     This is in answer to your letter of February 13, 1986.
You requested clarification concerning the regulatory status
of spent carbon used to remove dissolved pentachlorophenol (PC?)
from ground water.  You also asked what type of disposal facility
could properly dispose of this waste.

    Your letter indicates "product spillage" as the source of the
contamination.  If the product spilled was unused formulations
(EPA Hazardous Waste No. F027) and this is what migrated into
the ground water, the spent carbon is an acute hazardous
waste (F027), and, therefore, would be subject to the hazardous
waste regulations promulgated for dioxin-containing wastes.  It
this is not the case, the waste you describe is not subject to
regulation under RCRA.  In any event, you snould be aware
that the improper management of this waste could certainly be
hazardous to human health and the environment.  Regeneration of
the spent carbon would result in desorption and distribution ot
the chemicals it contained to air (in this case, pentachlorophenol
and chlorinated dioxins and -dibenzofurans are of principal
concern).  Land disposal of the spent carbon in a situation
whore solubilizing solvents are co-disposed could ultimately
result in once again polluting ground water.  Therefore, the
management of this waste should be carefully controlled.

    With respect to your request regarding disposal options,
incineration of this waste in a hazardous waste incinerator that
is permitted to burn PCBs is probably the most prudent option.
If you decide to incinerate you may wish to speak with Dr. Paul
dee Rosier^ of our Office of Engineering Research.  His telephone

Dear Dr. Tsengs

     Current U.S. EPA regulations control environmental releases
from wood preserving and surface protection facilities under several
Congressional statutes, including the Resource Conservation end
Recovery Act (RCRA), and the Clean Water Act (CWA).  Zn addition,
exposures of workers and consumers to the preservative formulations
during application  and usage of the treated wood is controllad by
the Toxic Substances Control Act (TSCA).  The current applicability
of the authorities  to environmental releases is smreaarized below,
along with a description of our present investigations under RCRA.

Wastewater Effluents under the CWA

     Process wastewaters effluent discharges from wood preserving
facilities which use arsenicsI/chromates, creosote, and/or penta-
chlorophenol are regulated under the Clean Water Act (CWA).  The
final regulations were promulgated in 1981 (46 PR 8260-8295) and
vary according to whether a facility was in existence at the time
of the regulation (pretreatment standards for existing sources,
PSES) or for new plants (new source performance standards, NSPS).

     The release of pentachlorophenol and creosote in wood preserving
wastewaters is controlled by the use of the indicator pollutant,
oil and grease.  The effluent standard for arsenic, chromium, and
copper is based on  specific concentration limits.  No discharge of
any wastewaters is  mandated for Boulton processes and non-pressure
processes.

     Process wastewaters for the wood preserving »ubcategory of
timber products is  defined as all wastewater sources excepting
noncontact cooling  water* Material storage yard runoff  (either raw
material or processed wood storage) and boiler blowdown  (4f fit
82ft? col. 2, 1 4).  However, precipitation falling in the  l/T~to
1/2 acre around the treating cylinders and tank areas is defined
as a process wastewater which must be collected and treated.
Guidance may be found in the Development Document for Effluent
Limitations and Guidelines and Standards for the Timber  Products

-------
Point Source Category (EPA Publication No.  EPA-440/1-81/023, p,
82), which
     "Rainwater that falls on or in the immediate vicinity of the
     retorts and work tank area—an area of from about on-quarter
     to one-half of an acre for the average plant—becomes contaminated
     and can present a treatment and disposal problem at any plant,
     but especially at plants in areas of high rainfall.  POT
     example, a plant located in an area that recieves 152 cm (60
     in) of rain annually must be equipped to process an additional
     1.5 to 3.0 million liters (400,000 to 800,000 gallons) per
     year of contaminated water."

Current Dioxin/Puran Chlorophenolic Regulations under RCRA

     Certain associated wastes from oil or water based Chlorophenolic
formulations used by wood preserving or surface protection facilities
(either at sawmills or at wood treaters before air seasoning) may
be subject to regulation as acutely hazardous wastes because of
their contamination with polychlorinated dloxins and furana under
the Resource Conservation and Recovery Act (RCRA).  The hazardous
waste listings which may apply are found in Part 261.31, Volume 40
of the Code of Federal Regulations as Hazardous Waste Nos. P020,
P021, P026 or P027.

     If a facility mixes Chlorophenolic formulations on-site, then
it may be covered by either the P020 (tri- or tatrachlorophenol)
or P021 (pentachlorophenol) listing if wastes are generated during
the process.  An example would be filtering the unused formulation
before storage, thus generating a filter residuaTT

     If a facility discards an unused (not spent) formulation
containing chlorophenolics the associated wastes and formulation
itself are covered by Hazardous Waste No. P027.

     If a waste is generated from the use of equipment (tanks, etc.)
that previously was used to mix Chlorophenolic formulations, then
these wastes would be covered by Hazardous Waste No. P026.  An
example would be mixing t-butyl tin oxide in the same tank that
was used for chlorophenoTics previously, and generating a filter
waste when the) TBO formulation was transfered to the process or
storage tank*

     A container or an inner liner removed from a container that
that has held an acute hazardous waste such as P020, P021, or
P027 must be either "triple rinsed* with an appropriate solvent or
cleaned by another established scientific method or the inner
liner must be removed and discarded (as a hazardous waste).
Otherwise, this container itself is considered to be the  hazardous
waste itself* either P020 or P021.  This regulation may be  found
In the Code of Pederal Regulations, Vol. 40, Part 261.7(a)(3).
Examples would be a storage tank taken out of service that  previously

-------
contained unused formulation, a formulation mixing tank, or erapty
chloroohenolic drums or kraft bags.

     when a wast* is listed as "Acutely Hazardous" under Part
261.31 (Hazard Code "(H)"), then special management standards
apply under RCRA over those normally imposed for other hazardous
wastes.  For example, under Part 261.5(a), generators of less than
1000 kilograms of hazardous waste a month would normally be exempt
from the management standards contained in Parts 262-265 and Parts
270 and 124 (surface impoundment specifications, ground water
monitoring, hazardous waste manifesting, etc.)*  Part 261.5(e)
instead states that the generation of 1 kilogram of acutely waste
generated a month or a total of 100 kilograms of contaminated
soils subjects the generator to the full management standards of
Parts 262-265, 270, and 124.

     (As described below, we are currently investigating the addition
of other wood preserving wastes to the acutely hazardous waste
categories because of their contamination with polychlorinated
dioxins and furans.)

Wastewater Treatment Sludges from Creosote and Pentachlorophenol
under RCRA

     At the present time, wastewater treatment sludges from wood
preserving processes which use creosote and/or pentachlorophenol
are regulated as Hazardous Waste No. R001 undar Part 261.31.  This
includes oil/water separator sludges, the sludges which form at
the bottom of surface impoundments used to treat or dispose of
wastewater (percolation or evaporation ponds), filter media (carbon,
sand, soil), spray irrigation fields (considered land treatment
units), sludge dewatering/drying beds, etc.

     There has been a lot of activity over the nast years in "closino"
unlined lagoons, ponds* etc. used for process wastewaters.  The
issue of "how clean is clean" for removing the sludges and contaminated
subsoils (much less pimping and treating contaminated ground water)
is decided on a case by case basis.  The criteria to be used for
closure of waste management units such as surface impoundments,
land treatment units, waste piles are given in Parts 265 and 267.

     If all contaminated materials cannot be removed, then post
closure care as specified under Part 265.310 is reguired.  This
would include maintaining a cover for the unit, leachate collection,
etc.

     The RCRA management standards would not apply to wastewater
treatment sludges  (or wastewaters if they are  listed as hazardous
wastes in the future) while they are managed on-site in tanks
which meet certain design requirements  (Part 264.1(n)(6) and Part
265.l(c)(10)).  However, as soon as the sludges are removed from
these units, the full RCRA permitting requirements apnly.  Many
facilities have therefore chosen to install wastewater treatment
trains in structures that meet our tank specifications, rather
than surface  impoundments, to avoid around water monitoring and
other RCRA oermittino

-------
Creosote or Pentachlorophenol Wastewaters under RCRA

     In 1980, we proposed to add wastewaters themselves from creosote
and/or pentachlorophenol facilities to the list of hazardous wastes
under Part 261.31 (45 PR 33137).  In 1984, w* started obtained the
necessary analytical data by site sampling missions to supnort
this oroposed hazardous waste listing.  W« have been obtaining
analyses of the wastewaters themselves as well as documenting
ground and surface water contamination with polynuclear aromatic
hydrocarbons (PAHs), chlorophenols, and polychlorinated dioxins/furar

     Since wastewaters are typically managed in the sane units
that manage the currently regulated wastewater treatment sludges
(Hazardous Waste No. K001), few additional controls of wastewater
units under RCRA would occur.  However, if wastewaters were listed,
we would have the authority of controlling such waste nanagement
practices as their "treatment" by evaporation in the treating
cylinder or the plant boiler.

     Any RCRA authority over wastewaters would be limited to their
management on-site at a facility (Part 261 .4(a) (2) [Comment) ) .
When released to the navigable waterways or sent to a publically
owned treatment work (POTW), the statuatory authority becomes the
Clean Water Act (CWA).  This means that it is possible to have
different toxic substances of concern or "action levels" for a
wastewater while it is managed on-site under RCRA than after release
off-site under the CWA.  For example, under RCRA we may be considerii
wastewater contamination with polychlorinated dioxins and furans,
yet the CWA standards currently only consider the indicator pollutan
oil and grease.

Inorganic Arsenical and Chroraate Wastes (Wastewaters, Sludges,
Contaminated Soils) under RCRA

     At the current time, any wastes generated by a wood preserving
facility that fails the "Extraction Procedure Toxicity Test" ( EP
Toxic) in a regulated waste.  This test procedure (described in
Appendix XX of Part 261) involves extracting the waste with 20
timea its, weight with water, adjusted to a pH of 5 with acetic
acid.  The extract is analyzed, thus yeilding the "EP Toxicity"
value.  If the sample is an aqueous liquid, then the sample itself
is analysed, giving the "EP Toxicity".

     The maximum allowable concentration for ttetallics in the "EP"
extract is compared to the values given in Table 1 of Part 261.24.
If either the total arsenic or chromium in th« "EP" extract exceeds
5.0 parts per million, then the waste is classified as either EPA
Hazardous No. D004 or 0007. respectively.
     Thus many inorganic salt wood preserving wastes are control
by the RCRA management standards of Parts 262-265,  270, and  124.
This would include contaminated soils in the treated wood drinr>an«
area, process wastewaters, sludges, snilled formulations, etc.

-------
     We are currently investigating whether or not to specifically
list inorganic salt wood preserving wastes under  Part 261.32.
This would aive the Agency the additional advantage of oversight
of treatment of all the wastes generated through  its delisting
process under Part 260.22.  Currently, for "EP Toxic" wastes, the
facility has the ability to determine on its own  whether or not 3
waste is hazardous and whether or not treatment is adeguate.

Corrective Action under RCRA

     As the result of the Hazardous and Solid Waste .Amendments
of 1934 (HSWA) (Congressional Records of Oct. 3 and 11, 1984), the
authority of RCRA has been extended to other solid waste management
units (SMUs) at facilities, even if these units do not not raanaae
a waste that is listed in Part 261.  This is the  corrective action
reguirement for continuing releases at permitted  facilities under
Section 3004(u) and (v) of HSWA.

     This requirement for permitting all solid waste management
units applies only to facilities that current have hazardous waste
management units subject to the permitting standards of RCRA.
Since few facilities, if any, have final permits, any plants with
surface impoundments managing K001 wastewater treatment sludges
must also obtain a permit for the treated woo-i drippage/storage
area, process areas, and any landfills.

     If there is any contamination in these areas (release) corrective
action must be undertaken.  A release from a solid waste management
unit is defined in terras of whether or not the unit is designed
for adequate containment.  For example, treated wood driopage
(currently a "solid waste" but not a "listed hazardous waste") is
typically managed by land disposal (dripcage to the ground).  This
ground usually does not have a clav liner, runoff containment,
etc.  Therefore, disposing of this drippage on the open ground
constitutes a release for the purposes of corrective action.
Leakage from a tank would also be a release.

Current Efforts under RCRA to List Additional Hastes

     At the- present time, our branch is involved  in investiaatinq
whether or not to add additional wastes from wood preserving and
surface protection facilities to the list of hazardous wastes
under Parts 261.31 and 261.32.  New wastes which  are being  considered
are listed below, and apply to either wood preservation or  surface
protection facilities and to any of the preservative formulation
types, whether creosote, chlorophenolics, or arsenical-chromates:

     •Storage tank, treating tank, retort, dip tank, spray  booth
      sludges

     •Treated wood drippage/storage residuals

     •Fugitive emissions, drippage in the process and  tank  area

     'Maintenance area, shop area wastes

-------
     •Wastewaters (including storm water runoff)

     •Wastewater treatment sludges from arsenical-chromate processes
      or chlorophenolics from surface protection processes


     All of these wastes, where applicable, are beina studied to
determine whether or not they should be listed as acutely hazardous
waste because of contamination with polychlorlnated dioxins and
furans.  This includes any wastes that can be cross contaminated
with chlorophenolics, such as wastes generated from a creosote process
where a common oil/water separator is used for both creosote and
pentachlorophenol, sludqes from an arsenical process that uses
pentachlorophenol make-up water, wastes from a non-chlorophenolic
dip tank that previously held chlorophenolics, etc.

     As described in previous sections, all of these wastes are
covered under the RCRA authority at some wood preserving facilities,.
especially because of the corrective action provisions under HSWA.
Very little coverage under RCRA currently exists for sawnills
practicing sapstain control, however.  Adding new waste streams to
the list of hazardous wastes would make hazardous waste management
standards uniform at all facilities, and ease the burden to State
and Regional enforcement personel in formulatinq a regulatory authority
rationale.

Mr. Gregory J. Harvey
Industrial Hygenist
Occupational Medical Services
Newark Air Force Station, OH  43057-5000

Dear Mr. Harvey,

     This letter is written in response to your request that  EPA
determine whether activated carbon canisters that are used to
collect vapors of the solvents Freon 113, 1,1,1-trichloroethane,
and methylene chloride, which are generated during the
application of certain paint products, are considered to be a
hazardous waste.

     As you are aware, the Agency has listed these compounds  as
hazardous wastes when they are used as solvents and have become
contaminated with physical or chemical impurities and are no
longer fit for use without being regenerated, reclaimed, or
otherwise re-processed.  Use as a solvent is defined as being
used for their solvent properties, that is, to solubilize
(dissolve) or mobilize other constituents.  For example, solvents
used as a cleaning or degreasing agent, a medium for chemical
reactions, an extraction agent, a diluent, and similar uses are
covered under the F001 through F005 listings under §261.31 of
RCRA.  These listings, however, do not apply when the solvents
are used as reactants or ingredients in commercial chemical
products  (e.g.. paint and coatings).  (See 51 FR 6538, February
25, 1986.)

     Since the incorporation of solvents into paint formulations
does not constitute solvent use as defined in the listing, the
solvent vapors collected from paint application are not spent
solvents.  Unless these canisters exhibit one or more of the
hazardous characteristics described under 40 CFR 261.20 - 261.24,
they would not be a hazardous waste under the Resource
Conservation and Recovery Act (RCRA).
            This has been retyped from the original document.

-------
     Nevertheless,  we believe that sufficient toxicological data
exists on these  solvents to indicate that the subject canisters
may pose a substantial present or potential threat to human
health or the environment,  if improperly managed.   We, therefore,
urge you to manage  these canisters with proper controls (i.e., as
if they were hazardous under Subtitle C of RCRA).

                                    Sincerely yours,
                                    Matthew Straus

Mr. Donald P. Duffy
Pace Laboratories, Inc.

Minneapolis, MN  55422

Dear Mr. Duffy:

     This letter is in response to your request for an
interpretation of the electroplating listings  (EPA Hazardous
Waste Nos. F006 and F019) .  Our responses to your specific
questions are as follows:

     1. "Electroplating operations" includes electroplating of
        common metals, electroplating of precious metals,
        anodizing, coatings, chemical etching  and milling,
        electroless plating, and printed circuit board
        manufacturing.

     2. The only phosphating processes that are not included  in
        the F006 listing are phosphating on aluminum.   These
        processes are included in the F019 listing.

     3. The exclusion "...(3) zinc plating (segregated  basis) on
        carbon steel..." refers to non-cyanide zinc plating
        processes.  That is, zinc plating processes which use
        cyanide are not excluded from the F006 listing.

     4. The zinc plating exclusion does not encompass any wastes
        from chemical conversion coating processes  (e.g.,
        chromating).  Thus, when chromating processes contribute
        to the wastewater stream, the resultant wastewater
        treatment sludges are included in the  F006 listing.

     5. The F006 and  F019 listings are currently being  re-
        evaluated.  At present, the primary focus of this effort
        is on phosphating processes; several trade associations
        are now gathering data to support our  re-evaluation.
             This has been retyped from the original document.

Dear Mr. Yancey:

     The purpose of this letter is to respond to your question
regarding the classification of sludge generated from treatment
of cleaner solutions at your Fort Smith, Arkansas facility.  It
is my understanding that the first stages of your phosphating
process are the cleaner stages.  Treatment of the wastewater from
the cleaning baths involves pH adjustment, flocculant addition,
and filtration.  The sludge that results from this treatment is
not considered listed hazardous waste as long as wastewater
generated from the listed process is kept entirely separate  (the
listed process occurs further down the line).  The cleaning
process is not a listed process, so this wastewater treatment
sludge is not listed.  This sludge may still be hazardous by
characteristic, however, and you will need to test for that.  If
you have any further questions, please do not hesitate to call me
at (202) 382-4519.

                                   Sincerely,

Dear Mr. Garden,

     The purpose of this letter is to confirm our telephone
conversation held on June 23, 1986 which dealt with the question
of whether the Lisle Corporation's manufacturing process should
really be considered an electroplating operation.  Based on the
information the Agency requested and received from Lisle
Corporation on June 23, 1986, the mechanical plating system is
not an electroplating operation as listed under 40 CFR 261.31.

     On May 19, 1980, the Agency promulgated as an interim final
rule the listing of "wastewater treatment sludges from
electroplating operations" in 40 CFR 261.31 as EPA Hazardous
Waste No. F006.  As indicated in Appendix VII of Part 261 (45 FR
74892), the constituents of concern for this waste are cadmium,
hexavalent chromium, nickel, and complexed cyanide.  (This waste
listing was finalized on January 16, 1981 (46 FR 4619) with some
modification).

     The mechanical plating operation utilized by Lisle
Corporation involves the deposition of metallic coating on a base
metal through mechanical action (i.e., impact of glass beads on
the object to be coated in the presence of the coating metal) and
is not considered an electrolytic process.  We feel, therefore,
that mechanical plating would not be considered an electroplating
operation as defined in the background document and that
wastewater treatment sludge previously generated from mechanical
plating operations would not be considered a listed hazardous
waste under 40 CFR 261.31 and thus, would not require delisting.

     This, however, does not mean that the wastes already
generated from this operation are non-hazardous.  Each generator
is ultimately responsible for determining whether his waste
exhibits any of the characteristics of a hazardous waste (i.e.,
ignitability, corrosivity, reactivity and EP toxicity) as
described in 40 CFR 261, Subpart C.  If the waste exhibits a
hazardous waste characteristic, the waste must be managed in
accordance with the hazardous waste management regulations.
            This has been retyped from the original document.

generated from this operation  are non-hazardous.  Each generator
is ultimately responsible for  determining whether his waste
exhibits any of the characteristics of a hazardous waste  (i.e.,
ignitability, corrosivity,  reactivity and EP toxicity)  as
described in 40 CFR 261, Subpart C.  If the waste exhibits a
hazardous waste characteristic,  the waste must be managed  in
accordance with the hazardous  waste management regulations.

2.  Spent Solvent Listings (5261,31)

    A manufacturing facility uses a liquid-liquid extractor  in its
    production process.  An influent water stream bearing  the product to
    be recovered contacts an influent stream of pure halogenated solvent
    flowing countercurrent.  The solvent stream preferentially absorbs
    the product fron the water.  The solvent bearing product stream exits
    the extractor.  Because the solvent is not completely  inmiscible
    with water, the production process yields an effluent  stream consisting
    of water and solvent at the other end of the liquid-liquid extractor.

    If the solvent used in the extraction process is a RCRA  listed
    hazardous waste when spent, would the water/solvent effluent stream
    be RCRA regulated?

         No; although extraction constitutes solvent use,  the effluent
         stream is not a spent solvent covered by the spent  solvent
         listings in 5261.31 as revised on December 31, 1985 (50 FR
         53315).  The effluent waste water stream became contaminated
         with solvent during the actual production process (i.e., during
         use of the virgin solvent) resulting from the incomplete
         miscibility of water and solvent in the extraction  process.
         It did not become contaminated as a result of spent solvent
         being discharged into it.  It/ therefore, would not be regulated
         as a RCRA hazardous waste, unless such waste stream were listed
         as a manufacturing waste in 5261.32 or exhibited  a  characteristic
         in Suboart C of Part 261.

Dear Mr. McAdams:

     I am writing in response to your request for a written
determination otf whether the "pre-coat" waste that you generate
as part of the process is a listed hazardous waste.  I have-
reviewed the information that you have submitted in your June 10,
1986, letter and conclude- that the use of 2-ethoxy«thanol in
your polypropylene extruding process does not constitute use as
a solvent.

     As you have stated in your letter* the spent solvents
listings do not cover manufacturing process wastes that, are
contaminated with solvents when they are used as rtactants or
ingredients in the formulation of commercial chemical products.
This is because the chemicals are not being used as solvents.
I am satisfied that you have provided sufficient evidence that
2-ethoxyethanol is an ingredient of the pre-coat formulation.
Thus, this pre-coat waste containing 2-ethoxyethanol is not a
listed waste.

     Although the subject waste is not a listed waste, 2-ethoxy-
ethanol is known to be teratogenic in animals by oral, inhalation,
and dermal routes* and causes adverse reproductive effects in
animals.  The concentration or 2-ethoxyethanol in your waste
(1 to 5%) is many times greater than the health-based values tor
2-ethoxyethanoi.  furthermore, the Agency has listed still
bottoms from the recovery of spent 2-ethoxyethanol because it
contains similar levels or th« subject solvent (1 to 10%).
Thus, this pre-coat waste may pose a substantial threat to
human health and the environment/ if improperly disposed and we
suggest that you manage it accordingly.


                                 Sincerely,
                                 Matthew A. Straus

Dear Mr. Porter:

     This is in response to your July 8, 1986, letter in which
you request written clarification as to whether your laboratory
waste, generated by an investigator performing research
using stock solutions of 2,3,7,8-tetrachloro-dibenzo-p-dioxin
(TCDD), is covered by the dioxin listings (EPA Hazardous Waste
Nos. F020, F021, F022, F023, F026, or F027).  These wastes
include animal carcasses, bedding, feces, urine and other
"typical" laboratory dry waste such as paper goods, gloves,
syringes, etc.

     The wastes which you described are not the listed dioxin-
containing wastes under 40 CFR §261.31.  These wastes would more
appropriately be defined at 40 CFR S241.101(h) as  infectious waste
"...laboratory wastes, such as pathological specimens (e.g.,
all tissues, specimens of blood elements, excreta, and secretions
obtained from patients or laboratory animals) and  disposable
fomites  (any substance that may harbor or transmit pathogenic
organisms) attendant thereto	".  To date, EPA has not
promulgated criteria for identifying waste as infectious
under §261 Subpart C.  The Agency has, however, developed a
manual  to provide guidance on the management of infectious waste.
A copy  is enclosed for your reference.

     I  hope this adequately answers your questions.  If you
have any further questions, please contact Doreen  Sterling of
my  staff.

                               Sincerely yours.

Mr. John L. Cherill

Dear Mr. Cherill:

     This is in response to your letter of May  15/  1986*
regarding the regulatory status of the reject substrates
containing vanadium pentoxide (as described  in  your May 15th
letter) under the existing Federal hazardous waste  regulations.
First/ I would like to apologize for taking  so  long in
responding to your request; I hope this delay has not caused
you any problems.  With regard to your specific request/  the
vanadium pentoxide substrate is not a listed hazardous waste;
therefore, this material (when abandoned) would only be,
subject to the hazardous waste regulations if it exhibits one
or more of the hazardous waste characteristics  (i.e./
ignitability/ corrosivity, reactivity, or extraction procedure
(EP) toxicity).  In response to your specific questions!

     1.  Would our reject substrates (prior  to  crushing)  be a
         hazardous waste, P010, because the  vanadium pentoxide
         component would be considered a "sole  active
         ingredient"?

         Ho.  The reject substrates are not  considered the
         listed hazardous waste P010.  P010, listed in 40 CFR
         261.33(e), covers unused vanadium pentoxide  (either
         pure grade/ technical grade, or in  formulations
         where it is the sole active ingredient) which
         is discarded.  Since the reject substrates are not
         considered the commercial chemical  product vanadium
         pentoxide, this material is not considered hazardous
         waste P010.

     2.  Would crushing the reject substrates (as we  normally
         do) make them a "process waste* which, since such
         process waste is not a listed waste under  261.31 or
         261.32 and would not exhibit any of the characteristics
         of a hazardous waste given at 261.20,  261.21, 261*22,
         261.23 and 261.24, is not a hazardous  waste; or,
         would such crushing merely be considered a "treatment"
         ot a halardous wasfe*Mcbi.»»>at<:t to a  KCRA varr n v*~*< + *-*

-------
         Crushing of the reject substrates would not be
         considered a process waste since this activity is
         not part of the manufacturing operation (i.e.,
         operation to manufacture the vanadium pentoxide
         substrate).  Rather, the crushing operation is a
         treatment process to reduce the waste volume of the
         off-spec substrates.  However, since the reject
         substrates are not hazardous wastes (i.e.,  are not
         specifically listed nor exhibit any of the  hazardous
         waste characteristics (as you indicate), the crushing
         operation is not subject to the hazardous waste rules.

     3.   Would the ultimate end user of this new product,
         e.g., a power plant, have to dispose of the spent
         product as a hazardous waste solely because it
         contained vanadium pentoxide?  (Obviously,  if the
         product as a result of its use captured arsenic or
         lead, for example, from the exhaust stream  and it
         then exhibits the characteristic of EP Toxicity it
         would have to be disposed of as a characteristic
         hazardous waste.)

         No.  Aa already indicated, the vanadium pentoxide
         substrate is not a listed hazardous waste.   Therefore,
         this material is not subject to the hazardous waste
         rules, unless this material exhibits one or more or
         the hazardous waste characteristics.

     Please feel free to give me a call if you have  any
further questions; my telephone number is (202) 475-8551.

                                 Sincerely,

MEMORANDUM

SUBJECT:   Repromulgation of F006 Hazardous Waste Category

FROM:      J. Winston Porter
           Assistant Administrator for Solid Waste  and
           Emergency Response

TO         Valdas V. Adamkus
           Regional Administrator

     Thank you for your August  18, 1986 memorandum  regarding
the repromulgation of the F006  hazardous waste category.

    After a briefing with the staff from the Office of Solid
waste, Office of General Counsel, and the Office of Waste
Programs Enforcement (OWPE), I  decided to re-interpret the F006
listing to only include those processes that can be implicated,
either directly or indirectly,  in the language of the  listing.
During this briefing, I was presented with five options which
are described in the attached material.  I selected option
three because it orovides a sound leaal argument and is cost
effective—it saves resources.  Realizing that ontion  three
may create problems with existing enforcement actions. involvina
F006 wastes, I have requested OWPE to develop guidance which
you should find helpful.  In addition, we expect to re-visit
the scope of the F006 listing as part of our relisting effort.

     The details of the decision are as follows:  the  F006
listing would include wastewater treatment sludges  from the
following processes:  (1) common and precious metals electro-
plating, (2) anodizing (3) chemical etching and milling and
(4) cleaning and shipping associated with common and precious
metal electroplating.  The following processes are  not included
under the. POO6 listina:  (1) chemical conversion coating,
(2) electroless plating, (3) printed circuit board  manufacturing
and (4) the six processes explicitly excluded from  F006.
Let me elaborate two fine points regarding the processes that
are not listed.  First, wastewater treatment sludges from  the
chemical conversion coating of  aluminum are listed  as  EPA
hazardous waste No. F019.  Second, wastewater treatment sludges
from printed circuit board manufacturing operations that
include processes which are within the scope of the listing
(i.e. chemical etching) are listed as EPA hazardous waste
No. F006.

-------
     We have drafted a Federal Register notice which oresents
our re-~interoretation of the F006 listing.  This notice has
been forwarded to the Regions for comment.  In addition, a
meeting was held with the Regions in Atlanta on September
16, 1986 to discuss our approach.
     I hope this memorandum and the attached briefing material
     ins how I made my decision and how I plan to proceed.

Dear Mr. Warren:

     This is in response to your letter of August 26, 1986,
in which you request that EPA confirm that soil contaminated
with Chlordane, as a result of application of that pesticide
in the normal course of agricultural use, would not automatically
be considered a hazardous waste.

     The pesticide Chlordane is a listed commercial chemical
product (U036; see 40 CFR 261.33(f)) that becomes a hazardous
waste when discarded or intended to be discarded.  The Agency
did not intend to cover those cases when the chemical is
released into the environment as a result of use.  (See, for
example, the enclosed memo regarding the regulatory status of
pesticide applicator washing rinse water.)  In addition, 40 CFR
261.2(c)(1)(B)(ii) specifically states that commercial chemical
products listed in Section 261.33 are not solid wastes (and,
thus, not hazardous wastes) if they are applied to the land
and that is their ordinary manner of use.  Therefore, the
contaminated soil would be treated as a hazardous waste (if
it is duq up) only if it exhibits one or more of the four
RCRA hazardous waste characteristics defined in 40 CFR 261.21
through 261.24.

     Please feel free to contact Mr. Matthew A. Straus if you
have any further questions; Mr. Straus can be reached at (202)

Re:  Status of Delisting Petition #0297

Dear Mr. Frank:

     The purpose of this letter is to inform you that the  Agency
has reevaluated its previous interpretation of the hazardous
waste listing for F006 wastes  (Wastewater treatment  sludges from
electroplating operations) and has determined that it is overly
broad.  In particular, we believe that certain of the processes
identified in the Listing Background Document that are not
directly or indirectly implicated in the actual listing are not
covered under regulations as listed hazardous wastes.  As  a
result, we now believe that F006 includes only common and
precious metals electroplating, anodizing, chemical  etching and
milling, and cleaning and stripping when associated  with these
processes.  On the other hand, the following processes are not
included under the F006 listing:  chemical conversion coating1,
electrolysis plating, and printed circuit board manufacturing2.
The Agency will be publishing an explanation of its  determination
on the F006 listing in the Federal Register in the near future.
     1Wastewater treatment sludges  from the  chemical conversion
coating of aluminum is listed as EPA Hazardous Waste No. F019.

     2Wastewater treatment  sludges  from  printed  circuit board
manufacturing operations that  include  processes which are within
the scope of the listing  (e.g., chemical etching)  are regulated as
EPA Hazardous Waste No. F006.

     Our records indicate that your petitioned waste is generated
from processes that are not  included  in the scope of the F006
listing as described above.  Therefore, we have discontinued the
review of your petition.  It should be noted that if your
petitioned wastes are mixed  with  listed F006 wastes or any other
listed hazardous wastes, the resulting mixture would be
considered hazardous.  Also, if your  petitioned wastes or any
mixture of wastes exhibit one or  more of the characteristics of
hazardous waste  (40 CFR 261  Subpart C) then that waste would be
considered hazardous.  If our records are incorrect or if your
petitioned wastes are mixed  with  other hazardous wastes for which
you still seek delisting, please  contact us as soon as possible
so that we can reactivate our review.  Also, please note that
this decision does not apply to any other listed wastes that may
be generated at your facility.

Dear Mr. Levin:

     This is in response to your March 19, 1986, letter  in which
you request written confirmation that the wastes generated from
the manufacture of 2,4,5-Trichlorophenol  (TCP) and
Hexachlorophene at your Beaumont plant are not covered by the
dioxin  listings promulgated on January 14, 1985  (see 50  FR 1978).
First,  I would like to apologize for my delay in getting back to
you; I  hope this has not caused you any problems.  With  respect
to your specific request, I agree that all of the wastes that are
described in your letter that are generated at your Beaumont
plant from 2,4,5-TCP and Hexachlorophene production are  not
covered by the dioxin listings (EPA Hazardous Waste Nos. F020-
027).'   As I  explain below,  these waste  are specifically excluded
activities are being carried out or were carried out in  the past,
the answer to these questions could change.  More specifically:

        Wastes from Manufacture of 2.4.5-TCP

        -  Wastewaters - I agree that the wastewaters that are
           generated in the 2,4,5-TCP process (i.e., streams 1
           and 2, as referred to in your letter) are not covered
           by the EPA Hazardous Waste Nos. F020 and F023
           listings.  If, however,  these wastewaters are treated
           on-site and a sludge is formed  (e.g., biological
           sludge, spent activated carbon, spent filter  aid,
           etc.), the sludge is covered by the listings  and would
           be regulated as an acute hazardous waste.   (See
           enclosed, March 29 1985, memorandum from Michael Cook
           to the Regions).
     :The only stream which I did not address is the spent sulfuric
acid from the manufacture of 2,4,5-TCP.   However, Mr.  Steven  E.
Silverman already addressed the regulatory  status of this stream in
a  separate  letter dated October 6,  1986.   Therefore, I  will  not
discuss  it  in this  letter.
             This has been retyped from the original document.

-------
     •  Wastes from Manufacture of Hexachlorophene Where Highly
        Purified 2.4,5-TCP is Used

        -  I agree with you (except as noted below) that all the
           wastes that are generated by this process  (i.e.,
           streams 3-11 and 13-19, as referred to in your letter)
           are not included within the scope of EPA Hazardous
           Waste Nos. F020 and F023).  I agree with Dr. Bellin
           that highly purified 2,4,5-TCP means any 2,4,5-TCP
           that contains less than 1 ppb of 2,3,7,8-TCDD.2  (You
           should be aware that if the Hexachlorophene Process at

     This level is much lower than that typically found in 2,4,5-
     TCP where the 2,4,5-TCP had not been highly purified.  See
     table 3 in listing background document to dioxin listing
     where it states that the concentration of 2,3,7,8-TCDD in
     trichlorophenols did range between 0.07 to 6.2 ppm.  In
     addition, based on discussions we had with manufacturers who
     use to produce hexachlorophene meeting FDA standards with
     respect to TCDD-contamination and their supplies of 2,4,5-
     TCP, the 1 ppb level of 2,3,7,8-TCDD was indicated as
     necessary in order to meet the FDA specification for
     Hexachlorophene.

Dear Mr. Rathsack:

     Thank you for your September 29, 1986, letter requesting
written confirmation that floating hollow plastic balls,
which are used to control vapors from industrial process
tanks containing carbon disulfide, would not be a hazardous
waste when disposed.

     As you are aware, carbon disulfide is listed in 40 CFR
261.33(e) as an acutely hazardous substance waste under the
Resource Conservation and Recovery Act (RCRA).  This listing
includes commercial chemical product, off-specification
species, container residues, or spill residues when any of
these are discarded or intended to be discarded.

     The plastic balls are a hazardous waste since carbon
disulfide has been incidentally deposited on them.  Cleaning
the balls should remove the carbon disulfide and render the
balls non-hazardous*  Simple washing may be sufficient for
this purpose.

     If I can be of any further assistance, please let me
know.
                              .Sincerely
                              Assistant Administrator

or the a^ent solvent listings (i._fc_-, EFA Hazardous Waste Noa.
P001, PC02, i?003. FOOH, and F005)• ' In your letter, you
discuss your understanding of these hatardous waste listings
and request that we determine- whether three specific wastes
are listed spent solvents.

     In funeral, jour understanding of the regulations related
to the identification ana classification or spent solvent
waste is correct.  However, below are tne criteria that we
use to determine whether a particular waste is a hazardous
spent solvent;

     1) the waste oust be a solid waste as defined in %0 CFR 261.2,

     2) the waste oust be generated as a result of tlu.- solvents
        belrio used for their solvent properties: that is, to
        soluoilise (dissolve) or mobilize otner constituents.
        (The listings do not cover aanui'acturing process wastes
        that are contaminated with solvents when the solvents
        are used as reactants or ingredients in the formulation
        of cooDercial chemical products.), and

     3) in the ease of solvent aixtures, tne oixturo oust contain,
        before use, a total of ten percent or more (b> volume) of

Dear Dr. Spiegelnan:

     This is in response to your  letter of September 17, 19S6,

specifically 4O Cx't< 261 and 40 C?R 26S,  to still oottoms generated
r'roi.i distillation of spent xylena frora the manufacture of sodium

latter.  During the recant months we  have boen using all available
resources to develop tiiu land disposal restrictions final rule  (51 PR
40572, November 7, 1900).

     A process waste containing solvents where the solvent ic a
reactctnL in the for:aulutio» of cocaoercial chesucal products are
aoc covered by tna spent solvent  listings (EPA Hazardous \.'^ut.e  Mos.
r'oUl, F002, F003, F004, and F005).  According to the information
provided in your letter, xylene is used as a react ant i.i the
manufacture of aodium xylenesulfonate, therefore, you ar« correct
in notiiKj that excess xylene frota this process would not. be
covered under the F003 solvent listing.   Still bottoms generated
fro.-n the distillation of the excess xylene would not be a hazardous
waste unless they exhioit one or  more of the characteristics of
hazardous waata (i.e., corrosivity, ignitability, EP toxicity,
or reactivity),  ifurtheriaore, as  you  correctly stated, spent
xylcae and still uottono from the recovery of xylene used in
your process does not meet the listing description for EPA haz*rdoui
Wttste aunber U239, since it is not a  discarded comi.*ercial chemical

     The first clans of wastes subject to the l&nd disposal re-
strictions effective November 3,  1936, include th«* F001-F005  solvents
and certain Uioxiu-containing wastes.  Therefore, the xylene
still bottoras generated from your process would nolt be subject
to these rules.  If these wastes  exliioit ono or more of the
caaractoristics of hazardous waste, they will be subject to the

Mr. Eliot Cooper

18400 W. 10th Avenue
Golden, CO  80401

Dear Mr. Cooper:

     Thank you for your letter of November 17, 1986, in which you
request clarification of the regulatory status of spent fluidized
bed media used during the destruction of listed hazardous waste
as well as clarification of facility changes allowed under
interim status.

     Under the RCRA regulations, spent fluidized bed media would
not be considered to be a hazardous waste via application of 40
CFR 261.3(d) since the spent media would not be considered to
have been derived from the treatment of a hazardous waste.  In
addition, the mixture rule in 40 CFR 261.3 (a) (2) (iv) does not
apply since the fluidized bed media is not a solid waste at the
time it becomes mixed with a hazardous waste.  Nevertheless,
spent fluidized bed media contaminated with a listed hazardous
waste  (or, in this case, a waste derived from a listed hazardous
waste) would still be subject to regulation since it contains a
hazardous waste.  See §261.3(c)(a) and (d)(2).  Therefore, the
treatment, storage, or disposal of spent fluidized bed media
contaminated with hazardous waste must be handled as if the
fluidized bed media itself were a hazardous waste.  However, if
the fluidized bed media, as a result of the incineration process
or as result of other treatment, no longer contains a hazardous
waste, it would no longer be subject to regulation under Subtitle
C of RCRA.  In this case, no delisting petition would be
required.

     Your second question concerns whether an interim status
facility may add a new incinerator if the facility currently does
not have an incineration process.  The answer is yes, provided
that the conditions specified in 40 CFR 270.72 are met.  Under
§270.72(c), owners or operators wishing to make any changes in or
additions to the processes of treatment,  storage,  or disposal at
an interim status facility are required to submit a revised Part
A and a justification for the change to the regulating agency for
approval.  EPA or an authorized State may approve these changes
only when they are necessary to prevent a threat to human health
and the environment due to an emergency situation, or when they
are necessary to comply with Federal regulations  (including the
interim status standards of 40 CFR Part 265) or State or local
laws.  This provision does not preclude the addition of a
            This has been retyped from the original document.

-------
completely new process (e.g.. incineration) at an interim status
facility that currently does not have such a process.

     It should be noted,  however, that §270.72(e) limits the
scope of any changes that take place at interim status facilities
by prohibiting changes that require a capital expenditure greater
than 50% of capital cost for the construction of a comparable
entirely new hazardous waste management facility.  Therefore,
this provision (known as the "reconstruction" limit) may restrict
the extent of a change even if the addition of a new process is
allowed under §270.72(c).

     The above response to your two questions describes the
operation of the Federal RCRA program for the situations you
outlined in your letter.   However, 42 States now have final
authorization to operate the RCRA program in lieu of EPA.  Some
State requirements may be more stringent or more restrictive than
the Federal program in these two areas.  If you have specific
concerns regarding your operation in Colorado, I recommend that
you contact Mary Gearhart in the Colorado Department of Health
(303-331-4830) since the State has RCRA authorization.

     If you have any further questions on the Federal RCRA
requirements, please feel free to contact Larry Wapensky in EPA's
Region VIII office in Denver (303-293-1660).

                                   Sincerely,

Dear Dr. Rambo:

     This is in response  to your letter of November 13, 1986,
requesting an interpretation of the federal hazardous vaste
rules concerning the disposal of spent ash following fumigation
vith aluainum and/or magneeiuia phosphide products.

     As you are aware,  aluainua phosphide is listed as a
hazardous vaste (1?A Hazardous Waste Ho. F006) is 40 CIS
§26l.33(e).  However, this listing only applies to the uamged
commercial product when discarded as the purs grade, tseamieal
grade, or *&«T» 1* i» the sole active ingredient in a
formulation!/.  Sines the product has been used, it veal* not
be considered the listed  hazardous vasts*  nevertheless,
the ash-residue of the  product would be hazardous aad subject
to the appropriate requirements if it exhibits any of the
hazardous vaste characteristics (i.e., ignitabllity, corrooivity,
reactivity, or extraction procedure (3?) toxicity) aad if the
srall quantity generator  (SQG) level (1 kg of total hazardous
waste calendar month) is  exceeded.  Thus, when the ash residue
is collected, the generator is responsible for determining if
it exhibits any of the  hazardous waste characteristics; if it
does, the additional processing of the residue (i.e.Xexpose
to air or place in a water detergent" bath) must be managed in
accordance with 40 CPR  Farts 262 to 266.

     If you have any further questions, olease feel free to

Albuquerque, NM  87131

Dear Mr. Verploegh:

     This is in response to your October 21, 1986 letter in which
you requested clarification as to whether your laboratory waste,
generated by an investigator, performing research involving
2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is covered under 40
CFR §261.31.  The wastes in question are:  1.07 mg of TCDD
contained in some 361 mouse carcasses, 450 gallons of cages and
bedding, and 41 gallons of dry waste.

     The wastes which you described are not the listed dixoin-
containing wastes under 40 CFR §261.31.  Rather, these wastes
would more appropriately be characterized as infectious wastes,
11. .. laboratory wastes, such as pathological specimens  (e.g. , all
tissues, specimens of blood elements,  excretes, and secretions
obtained from patients or laboratory animals) and disposable
fomites  (any substance that may harbor or transmit pathogenic
organisms) attendant thereto—" see 40 CFR §241.101(h).  To
date, EPA has not promulgated criteria for identifying waste as
infectious under §261 Subpart C.

     The Agency has, however, developed a manual to provide
guidance on the management of infectious waste.  A copy is
enclosed for your reference.  You should be aware that typical
infectious waste incinerators are probably not satisfactory
devices for disposal of materials highly contaminated with TCDD.
TCDD decomposes above 800C.   These wastes which you describe can
be safely managed by high temperature incineration.

     I hope this adequately answers your questions.

           Sincerely yours,

Suite 700

Washington, D.C.  20007

Dear Mr. Mottj

     Thank you for your November 5, 1986, letter regarding
the September 22, 1986, correction notice (51 PR 33612) for
the spent pickle liquor final rule  (51 PR 19320, May 28,
1986).  You stated that the correction notice dramatically
changed the spent pickle liquor final rule without prior
notice and comment.  You, therefore, argued that the Agency
violated the Administrative Procedure Act because the Agency
did not provide notice and comment, §4, 5 U.S.C. $553 (1966).
You also argued that adoption of the correction notice by the
State of Tennessee violates the Tennessee Administrative
Procedure Act.

     We disagree with your argument that our action has
violated the Administrative Procedure Act.  We think that
the Agency's intent throughout the rulemaking process has
been to list, as a hazardous waste, spent pickle liquor from
steel finishing operations from facilities within the iron
and steel  industry, and that the Agency stated this intention
clearly and repeatedly.  In fact, until your letter, there
has never  been any question, or even assertion, that the
listing is limited to only those facilities actually producing
iron and steel.  Thus, in the September 10, 1985, proposal
that led to the May 1986 final rule, the Agency explained
that the whole debate revolved around the question of whether
the Agency's existing K062 listing applies to pickle liquor
generated  by any steel finishing operation -or only from
those steel finishing operations in the iron and steel industry.
See, e.g.  50 PR 36966/1} 36967/1; 36967/2.

     The Agency laid out several options to resolve the
issue, including whether the listing "applies only to K062
wastes generated by the iron and steel industry*, (id. at
36968/1).  The reference to the "iron and steel industry"
referred to facilities in Standard  Industrial Codes (SIC)
Codes 331-332, as shown by the Agency's reference to those
SIC codes  (id. at 36966/1), as well as, the regulatory lan-
guage in §261.3(c)(2)  (ii).

-------
     The final regulation adopted the option of narrowing
the K062 listing to wastes from facilities within the iron and
steel industry.  In particular, we statedt

         "The Agency believes that the petitioners and the
          conmenters to the September 10* 1985, proposed rule
          have a valid argument that the listing should be
          read to apply only to those facilities within the
          iron and steel industry." £emphasis added](51 FR '
          19321/2)

         "Therefore, in light of the comments received and
          arguments made, the Agency had decided to modify
          its interpretation and narrow the scope of the spent
          pickle liquor listing to apply to those facilities
          within the iron and steel industry." Cemphasis
          added] (51 FR 19321/2)

         "This amendment will have no adverse economic impact
          on small entities since the rule will reduce the
          hazardous waste requirements to those persons who
          generate spent acid in non-iron and steel industries."
          [emphasis added] (51 PR 19322/1)

         "The majority of comroenters strongly supported the
          petitioners' claim that the plain language of the
          listing for spent pickle liquor from steel finishing
          operations...indicates that the listing applies
          only to facilities within the iron and steel industry."

     •me final rule mistakenly applied to facilities producing
iron and steel.  The preamble to the final rule also occasionally
referenced  this error.  The rule did not reflect the Agency's
intent and  could not reasonably be viewed as doing so.  The
Agency (as  shown above) did not propose such a limited con-
struction,  and received no comments suggesting such a restricted
listing nor was the regulatory language consistent with the.
preamble language cited above.

     It should also be  noted that the May 1986 regulatory
language contradicted the language of another regulation
regarding waste K062 and so did not reflect the Agency's
intent and  could not reasonably be considered to do so.  In
particular, li»e  stabilised waste pickle  liquor sludge from
the iron and steel  industry liquor  (SIC codes  331-332) had
been exempted from  the  "derived from" rule under  $261.3(c)(2)
 (ii).  See  49 PR  23284, June 5, 1984.  Thus, a listing of
pickle liquor only  from facilities producing iron and steel
would have  made the listing narrower than the  parallel exclu-
sion for sludges  derived  from  treating the listed waste,  we
repeat that such  a  factual contradiction  could not be deemed
to reflect  the Agency's intent, and  so could be changed by
means of a  technical  correction.  The Agency indeed noted
this contradiction  in making the  technical correction.  51
FR 33612/2.

-------
     Therefore  the Agency believes that it has not violated
the Administrative Procedure Act.  We believe that the
regulated community is clear on the issues involving the
pickle liquor listing as evidenced by the comments received
on the Septebmer 1986, proposed rule.  Also, the Agency
believes that the commenters and the regulated community
understand that the iron and steel industry is defined as
SIC codes 331 and 332 (as stated in the June 5, 1984, final
rule).

     In support of this position,the Agency received numerous
calls from the regulated community and State officials ques-
tioning the contradictory language in the preamble and final
rule.  Many of these callers indicated that the preamble
language of the final rule indicates that the listing applies
to all facilities within the iron and steel industry while
the rule addresses facilities that "produce" iron and steel.
The Agency recognized the contradiction as pointed out by
callers and responded with the September 22, 1986, correction
notice.

     Thus, in light of the phone calls received by the Agency
addressing the contradictory language in the preamble and
regulatory language of the May 1986, final rule, the Agency
concludes that the regulated community understands that the
Agency made an error in the final rule, and that it did not
have "a belated change of heart in the nature of the rule"
as you allege.  Furthermore, the Agency has difficulty under-
standing the practical consequences to your client of the
corrected regulatory language.  You indicate that Bristol
recycles all pickle liquor and rinse water*  We would be
interested in an explanation of what operations at Bristol
are regulated and which regulations would apply.

concerns.  If you have questions, please contact Matthew
Straus or Jacqueline Sales at (202) 475-8551.

Re: Status of Delisting  Petition  #0507

Dear Mr. Barrett:

     The purpose of this letter is  to inform you  that  the  Agency
has reevaluated its previous  interpretation  of  the  hazardous
waste listing for  F006 wastes (Wastewater  treatment sludges from
electroplating operations)  and has  determined that  it  is overly
broad.  In particular/ we believe that  certain  of the  processes
identified in the  Listing Background Document that  are not directly
or indirectly implicated in the actual  listing  are  not covered
under the regulations as listed hazardous  wastes.  As  a result,
we now believe that P006 includes only  common and precious metals
electroplating, anodizing,  chemical etching  and milling, and
cleaning and stripping when associated  with  these processes.
On the other hand, the following  processes are  not  included under
the F006 listing:  chemical  conversion coating V, electrolcss
plating, and printed circuit  board  manufacturing  £/.   The  Agency
recently published an explanation of  its determination on  the F006
listing in the Federal Register £/.

     In addition,  the Agency  notes  that your petition  also
identified the subject waste  as EPA Hazardous Waste No. K062
The Agency has recently  revised the scope  of the  K062  listing
to include wastes  from only those facilities described by
V Wastewater treatment sludges from the chemical conversion
   coating  of aluminum is listed as EPA Hazardous Waste
   No.  F019.

£/ Wastewater treatment sludges from printed circuit board
   manufacturing operations that include processes which are
   within the scope  of the listing (e.g., chemical etching)
   are  regulated as  EPA Hazardous Waste No.  F006.

    see  51  PR 43350 ,  December 3, 1986 for an explanation of
                                                              M.S. 00 : l*IJ-4*7-l!3

SIC codes 331 and 332.  Based upon discussions with Mr. Richard
Bohaychyk of Teledyne, we have concluded that the SIC code for
your facility causes the waste to not meet the K062 listing
description.^/

     Our records indicate that your petitioned waste is generated
from processes that are not included in the scope of the F006
listing or that of the K062 listing, as described above.  Therefore,
we have discontinued the review of your petition.  It should be
noted that if your petitioned wastes are mixed with listed F006
wastes, listed K062 wastes, or any other listed hazardous wastes,
the resulting mixture would be considered hazardous.  Also, if
your petitioned wastes or any mixture of wastes exhibit one or
more of the characteristics of hazardous waste (40 CFR 261 Subpart
C) then that waste would be considered hazardous.

     If our records are incorrect or if your petitioned wastes are
mixed with other hazardous wastes for which you still seek
delisting, please contact us as soon as possible so that we can
reactivate our review.  Also, please note that this' decision does
not apply to any other listed wastes that may be generated at
your facility.

     If you have any questions regarding this matter, please
contact Myles Morse of my staff, at (202) 382-4788.

                                 Sincerely,

Honorable Lloyd Bentsen        ""   •< 9
961 Federa-1 Building
Austin, Texas  78701

Dear Mr. Bentsen:

     Thank you for your November  29^,  1986, letter requesting
information concerning the  regulatory status of electric arc furance
(EAF) dust generated by the Bodner Metal and Iron Corporation of
Houston, Texas, after treatment with  Lopat Industries; K-20
encapsulation process.  My  office has reviewed the material supplied
with the letter, and has concluded that the encapsulated EAF dust is
still a hazardous waste under the Resource Conservation and Recovery
Act (RCRA) and should be managed  as such.

     The Texas Water Commission,  in its letter of November 7, 1986,
to Emanuel Bodner of Bodner Metal and Iron Corporation, was correct
in its assessment of Bodner Metal and Iron's EAF dust.  This EAF
dust is a listed hazardous  waste  (EPA Hazardous Waste No. K061)
under 40 CFR $261.32.  The  hazardous  constituents for which this
waste was originally listed are hexavalent chromium,*lead, and
cadmium.  A listed waste must be  handled as hazardous, even, if
treated, unless a regulatory exclusion  ("delisting") is granted.

     The delisting process  requires detailed sampling and testing
of representative samples of the  waste generated a particular
facility.  Oelisting decisions are based on the characterizations
of the wastes generated at  individual facilities.

     The standards that a waste must  meet to be delisted are more
stringent than the standards set  in the RCRA regulations for the
hazardous waste characteristics.  These characteristics (i.e.,
extraction procedure  [EP] toxicity, reactivity, corrosivity, and
ignitability) wore established to bring non-listed wastes which
exhibited any of these characteristics under hazardous waste
regulation.  After the promulgation of the Hazardous and Solid
Waste Amendments of 1984 (HSWA),  the Agency is now required to
evaluate all wastes,  for which a  delisting is sought, for their
originally listed constituents of concern and for any "Appendix
VIII" hazardous constituents reasonably believe to be present in
the waste, as> well as the hazardous waste characteristics, in each
delisting demonstration.

-------
     It should be noted that the two series of EP toxicity tests
performed on samples of treated EAF dust (the results presented
with Mr. Bodner's letter of November 10, 1986) have produced leachate
concentrations for lead that are too high to justify a delisting.
The Agency uses a vertical and horizontal spread (VHS) dispersion
model to aid in the evaluation of delisting petitions.  This model
uses leachate dat and waste volume to predict potential impacts of a
waste upon ground water.  The EP leachate data for lead (1.6 and
3.6 mg/1) in the treated waste, as presented in the Bodner letter,
will produce compliance-point concentrations which fail the VHS
evaluation (i.e., the compliance-point values exceed the National
Interim Primary Drinking Water Standard for lead of 0.05 rog/1).
The Agency has required that other stabilization technologies
employed in several other delisting petitions achieve EP leachate
concentrations for lead below 0.3 mg/1.  Several petitioners have
been successful in achieving these leachate levels.

     Although it would not change the regulatory status of the EAF
dust the Agency does believe that encapsulation processes (such as
the Lopat K-20 process) are useful in controlling the mobility Of
hazardous wastes and thereby decreasing the probability of
environmental contamination.  To assure that stabilizing treatment
technologies will successfully bind constituents over the long
term,, the Agency requires stabilized wastes to be ground to a
uniform 100-mesh particle size prior to chemical testing.  This
provides the Age-ncy with a means of evaluating the waste for the
potential effects of weathering or mismanagement.

     I hope this information addresses your concerns.  If you have
any additional questions concerning the delisting of hazardous
wastes, please contact Mr. Myles Morse, of my staff, at (202)
382-4782.

                          Sincerely yours,
