The chemicals in  the first three (3)  classes  will be obvious to those with a chemistry
background.  EP toxics are from a restricted list composed of heavy metals (e.g.  Arsenic,
Lead, Mercury plus 5 others) and specific chlorinated hydrocarbons (e.g. Endrin, Lindane,
2,4-D).  Acutely hazardous  materials are mostly other  halogenated hydrocarbons  and
pesticides.  Toxic wastes are all  others that carry toxic limits for ingestion, inhalation, or
skin contact.  (Appendix 3).

1.  Laboratory Waste Management Guidelines and Waste Packaging Guidelines have
    been separately published and distributed to AWBERC Laboratory Personnel. Consult
    these  Guidelines for explicit instructions on waste matters.

2.  Requirements for sink/sewer disposal conform not only with Federal Regulations and
    EPA  Policy Guidelines, but also with Metropolitan Sewer District  (MSD) permit
    specifications.

3.  The common acids and bases in the pH range 6-10 may be disposed of in sink drains
    with adequate flushing.  Higher and lower pH materials  must be  neutralized  first (see
    Section 11, A, 3 of Waste Disposal Manual).

4.  Aqueous  and  non-aqueous waste mixtures should  be separately collected,  unless
    impossible by nature of test or process. Further, unstable and incompatible chemicals
    must  not  be combined (Appendix 4). Finally, no material may be chemically treated
    simply to facilitate waste disposal - per strict RCRA requirements.

5.  RCRA hazardous characteristics  can be  expensive and  time consuming to establish.
    The generator may  utilize prior  knowledge in  lieu of chemical  analysis to  facilitate
    proper identification of a chemical waste.  That  same knowledge will maintain a waste
     minimization program in each laboratory of AWBERC. (Appendix 6).

 6.   Permitted inorganic compounds may be poured  into the sink drain in limited quantities
     with sufficient water to clear the drain traps and leave  them full.

 7.   Many organics may be poured into the drain if:

     a.  solubility in water is greater  than 3%;
     b.  vapor concentrations will not exceed 3(K) ppm;
     c.  they  are of low toxicity, and non-explosive;
     d.  they  are degradabie at the treatment plant; and
     e.  they  are not on the list of high  Henry's Law
        solvents in Appendix 1, Table 3.

 8.  A  formal safety inspection  of the AWBERC  Waste Storage Facility will  be made
     weekly (Appendix 5,  checklist), and a  similar inspection is encouraged  for  each
     AWBERC laboratory by the supervisor  on a periodic  basis.

 9.  Disposal of hazardous materials via a commercial disposer requires special preparation.
     (Appendix 7).

     a.   Secure packaging and identification
     b.  Completion and routing of EPA-Form 385

             Management of  Wastes  at AWBERC

Introduction;  Research, office work,  construction and other
activities at the AWBERC generate a variety of hazardous and
non-hazardous wastes which must be disposed of.  In order to
properly manage the disposal  of all of these types of wastes,
a comprehensive waste management program has  been established.
It is the overall  policy of  the  EPA-Cincinnati,  in carrying
out its research mandate,  to take all reasonable precautions
to protect workers, the community, and the environment.  This
program has  been designed  to meet federal,  state,  and local
regulations,  protect  the  community  and   the  environment,
provide for the  routine disposal  of most wastes and minimize
disposal costs.  While  the  primary concerns in managing the
wastes are health,  safety and the environment, disposal costs
cannot  be  ignored.   The  cost for disposing of  an  excess
chemical  is  often  more   than the  initial  price  of  the
chemicals.

Waste(s) in this Manual is used in the general sense, to refer
to unwanted  material.   Any material can become  a  waste and
assume  a  negative  dollar  value.   If  the material  is  in an
unopened container, it can often be exchanged; but if no one
else will accept it, the material  becomes a  waste and must be
disposed of.  Most  wastes are generated  during the conduct of
an  experiment  and cannot  be recycled.    Once  a   waste  is
generated  or discovered  there is  an  legal  obligation  to
properly dispose of it.  Some examples  of  wastes are unused
chemicals, orphaned chemicals, unlabeled containers, materials
from a spill cleanup, trash,  and animal wastes.

Guidelines are presented in this Manual for the disposal of
most of the materials generated at AWBERC; however, there will
still be some circumstances which require special attention.
For example, when there is a mixture of two types of hazardous
materials, the  waste cannot  be handled  in  the usual manner.
If there are questions, please contact the SORD office (7969)
for clarification  or assistance.

-------
A.  Waste Categories:

    1.   Ordinary Wastes

        Ordinary wastes are those materials which are of a non-hazardous nature.
        These  materials pose no  unusual hazard to the  persons handling the
        material or to the environment.   Ordinary wastes, also  called general
        wastes, can be placed in a sanitary landfill.  Examples of  ordinary waste
        are:     Office  wastes, packing  materials  and  disposable  lab  ware
        (uncontaminated). These kinds of materials can be placed in the facility
        refuse  (i.e., dumpster).

    2.  Chemical Wastes

        This category covers a variety of materials. The waste chemicals may be
        of a non-hazardous  or hazardous nature, liquid, gaseous, or solid  or  in
        solutions of various concentrations.

    3.  Biological  Wastes

        Any waste containing animal parts, tissues or contaminated  with potentially
        infectious agents are considered biological wastes.  Biological wastes often
        contain toxic or radioactive materials and must be stored, handled, and
        disposed  of  in a manner  that is consistent with  all of  the hazardous
        materials present.

    4.  Radioactive  Wastes

        Radioactive  materials require special handling. The procedures for the
        disposal of radioactive materials are described in the Radiation Safety
        Manual.

     5.  Super-Toxic Wastes

        Dioxins, and other super-toxics are not normally handled at AWBERC and
        are not covered  in  this manual.  Consult the Safety Officer for safe
        disposition procedures.

-------
B.  Responsibilities

    Five areas of responsibility essential to the success of a Waste Management
    Program are those of the director, the supervisor, the  laboratory worker, the
    program waste control  officer, and  the  center waste  control officer. These
    responsibilities are described below:

    1.   Director/Management

        Management has the  overall responsibility  for the proper disposal  of
        wastes from the AWBERC Facility.

    2.   Supervisor Responsibilities

        Supervisors have the major responsibility for the proper management  of
        wastes  generated in their  laboratory, and  for  maintaining  a  Waste
        Minimization Program.

    3.   Employee Responsibilities

        The laboratory worker has  a major  impact  on the  success of the
        Hazardous  Waste   Management  Program  because  the  separation.
        identification and packaging  of waste  begins in the laboratory.   The
        laboratory  worker  should  know what  materials are  present in the
        laboratory, their age, their physical,  chemical and toxicity characteristics.
        and any associated hazards; how to manage a spill, and how to  ultimately
        dispose  of each  compound even before  it  is ordered.   The  generator
        (laboratory worker)  is therefore expected to:

        a.  Dispose  of radioactive materials, chemicals, biological wastes and
            ordinary trash according to the disposal guidelines tor these materials.
            The laboratory worker is responsible  for all materials and especially
            hazardous  materials from the time they  are ordered  until  they have
            been disposed of or properly packaged and accepted for disposal  by
            the Safety Office.  In addition to starting materials, reaction products
            which are produced during the  experiment must  be disposed of.

        b.  Assist in identifying unknown chemicals. In order to properly store,
            handle,  transport,  and  dispose  of  chemicals,  the  identity and
            concentration must  be known.  Occasionally, materials may be of a
            proprietary nature and the original manufacturer or producer is in the
            best position to provide the information  necessary for managing the
            disposal of  the  material, via  his  MSDS information.  Commercial
            disposal companies will not accept chemical wastes for  a sanitary
             landfill, incineration, treatment  or burial in a secure  landfill without
            an  accurate description of the materials.  An analysis by the disposer
            can be  very expensive, costing over $400. This charge can often  be
             avoided with advance planning.  Proper labeling  of materials and

-------
    periodic house cleaning greatly reduce the amount of unknown and
    orphaned  chemicals.

c.   Package and label chemicals for storage, transportation, and ultimate
    disposal.  The Hazardous  Materials Transportation  Act (also  called
    DOT requirements) has specific requirements tor packaging hazardous
    material for transportation which are strictly enforced. The generator
    (researcher) is expected to properly package the  waste and take it to
    the hazardous waste storage area. The Safety Office will then arrange
    tor the individual  containers  to  be  packaged  according to DOT
    requirements for shipment to the disposal  site via a commercial
    disposer.

d.  To keep the volume  of unwanted  chemicals   and wastes to  a
    minimum, maintain an effective Waste Minimization Program. It is
    inevitable that there will be  materials left over at the end of an
    experiment that must be disposed of. An excess  of starting materials
    must be  ordered, since  it  is unlikely that needs will exactly equal the
    amount ordered. In order to reduce the volume  of wastes, order the
    materials in smaller units. Occasionally, it may  help to order more
    than one size of unit.  For example, suppose 5-gallons of solvent are
    needed for an experiment;  ordering 4 one-gallon bottles and  4 one-
    liter bottle will  prevent having more than one liter in an  opened
    container to dispose of. Further toxic wastes can often be effectively
    reduced by micro-techniques.  For details about specific methods, see
    "Prudent Practices..."*

 e.  Substitute non-hazardous  or less  hazardous  materials  for  more
    hazardous ones. Chromic  acid is toxic and  also difficult to dispose
    of, but tor many uses adequate substitutes are available.

     National Academy Press, Washington. D.C., 1983.
                           8

-------
   f.  Recycle unused materials to other persons if possible. Many workers
      will  accept unopened containers,  hut  will not accepted opened
      materials of questionable purity tor lengthy, expensive and important
      experiments.  If the  method explained in "d"  above  is used,  the
      unopened containers may be acceptable to another worker. As part
      of the Waste Minimization  Program required by RCRA, a list of
      chemicals will be circulated.  Any chemical on the list is available tor
      recycling.

   g.  Dispose of non-hazardous  materials yourself. Many non-hazardous
      materials  can be disposed of in the sanitary sewer system. A list of
      materials and the quantities which can safely be poured into the sink
      are described in another section.

   h.  Neutralize chemicals  in your laboratory so that  they can be safely
      disposed  of in  the sink. Concentrated solutions of acids or bases
      cannot be poured directly in the drain, but after neutralization many
      of these materials can be conveniently and safely poured down the
      drain.

   i.   Segregate wastes according to directions. Do not mix hazardous and
       non-hazardous wastes together or the entire mixture must be treated
       as hazardous. Often non-haiogenated solvents (hexane, etc.) must be
       separated from  halogenated compounds to be accepted by commercial
       disposers. Both of these types of compounds are usually incinerated,
       but under different conditions.

4.   Collateral Duty Safety Officer (CDSOt Responsibilities

    The CDSO will coordinate the Waste Disposal Program for his respective
    area.   The CDSO will  also  be  responsible  for managing  the  funds
    necessary for disposing of the wastes when a commercial disposer is used.

 5.  Responsibilities  of the  Environment.  Safety  and  Health
      CESH) Office

     The  ESH Office will provide  advice and  assistance
     to  researchers  about  methods of  disposal, suitable
     containers, etc.   The ESH Office will also  be
     responsible for arranging the contracts with
     commercial disposers,  the AWBERC generator  permit,
     preparing the annual  Ohio EPA reports,  providing
     storage facilities, transporting the  wastes  to
     off-site permitted disposers, and keeping the
     disposal records  (manifests).

-------
II.   DISPOSAL PROCEDURES

     A.  Disposal of Ordinary (Non-Hazardous) Wastes

         1.   Material for the Sanitary Landfill

             The bulk of the nonhazardous materials are handled by the janitorial staff.
             It is therefore the  responsibility of the laboratory worker (or generator)
             to ensure no hazardous materials are placed in waste paper baskets, etc.,
             which are emptied on a routine basis and the contents placed in  the
             dumpster. Any containers for pickup and disposal by the janitorial staff
             must be clean and  free of contamination both inside and outside.  Broken
             glass, sharp and pointed objects, etc., must be separated from paper and
             placed in approved containers so that injuries do not  occur in handling
             these wastes.  (The EPA generator or the Collateral  Duty Safety Officer
             calls the "trouble  desk" to arrange pickup and  disposal of broken and
             unbroken  glassware;  no glassware with  "radioactive"  markings will  be
             picked up by building service personnel).

             In order to prevent hazardous materials from  being  placed in a sanitary
             landfill, it must be obvious that the waste is non-hazardous.  If the waste
             is of a suspicious nature such as drums, bottles, tanks, or any container,
             which might contain hazardous substances, information must be provided
             to prove that  it is non-hazardous before the waste will be accepted at a
             sanitary landfill. This information must be supplied  by the generator.

             No liquids should  be placed in the dumpster and no  free standing liquids
             will be accepted at sanitary landfills.

             Glassware Disposal at AWBERC distinguishes  between contaminated and
             uncontaminated,  broken and unbroken, large and small.  The  handling
             procedure is outlined in Appendix 1.

-------
2.   Chemicals Suitable for Sink Disposal at AWBERC

     A basic principle of federal EPA frowns on the notion that
     the "solution  to pollution is  dilution."   However,  a  more
     fundamental belief of human safety/survival is that there
     are gradations of quantity (absolute and relative)  that make
     hazardous materials, dangerous in a pure state, of reduced
     hazard in lower concentrations,  and ultimately "safe" at
     some very low (or "threshold") concentration.   This is to
     say that chemical toxicity is dosage-related.

     The guidelines set forth below take into account both of
     these principles, the nature of laboratory work, and the
     fact that the AWBERC Facility enjoys a high dilution factor
     by its intrinsic water usage rate, prior to its discharge
     into the Metropolitan Sewer District's  (MSD's)  System.   The
     restrictions which MSD imposes embody environmental concerns
     and human safety concerns inasmuch as it operates a treatment
     plant for processing drinking  water to county residents.  The
     guidelines  also  reflect the  EPA's  desire  to be  a  good
     corporate citizen with respect to its own regulations, as well
     as to be an exemplar of responsible behavior for all citizens
     and other corporate  units in society.  For these reasons, some
     chemicals are not acceptable in the sink/sewer system at any
     level.  (See F, G, below).

     Considering the more than 10,000 chemicals which are available
     in the AWBERC Facility,  these guidelines may  appear to name
     only  a  limited  number  of potentially  hazardous  materials.
     However, any facility which enjoys an  operational  permit is
     required to meet high levels of professional responsibility;
     this is particularly incumbent on the professional personnel
     of the EPA'S own facility.  If  you have any questions about
     the interpretation of these guidelines, consult 1)  the Waste
     Manual  (Rev. 1993);  2) your Collateral Duty Safety Officer;
     and/or 3) the SORD Office Waste Coordinator.

b.   To assure  a safety factor between  an AWBERC sink
     and MSD's POD of about 10-fold, it is assumed that
     no one lab is  discharging  more than  1500  ml per
     min..  or  15 labs  discharging the  same   material
     simuItaneous 1 v at more than 100 ml/min.  The column
     marked  "cone,   thres."  (concentration  threshold)
     converts  absolute  quantity   levels  of gms.  per.
     minute  into  %  concentration  limits for  liquid
     discharge, using AWBERC's daily water volume usage
     rate.

     Satellite  labs  (T&E,  Center Hill,  Newtown)  must
     translate  the  MSD  "point-of-discharge   (POD)  to
     their  own sinks' allowed  discharge levels, based
     upon the intrinsic dilution factor from their water
     usage rate.  They will also adjust their discharge
     limits  to  account for  special  conditions  (e.g.
     night  vs  day,  continuous vs plug discharge, etc.)
     at their facility.
                              12

     c.    Solvents  of  low  water  miscibility,   but  high
          volatility (i.e., high Henry's Law constants), when
          pure or exhibiting a distinct phase, like methylene
          chloride and benzene/toluene/xylene,  should not be
          sink-discharged.    When  solubilized  in  another
          vehicle, the threshold and quantity limits in a and
          b apply.   For larger quantities, call  the Safety
          Office.  For more than liter quantities, convey to
          the Waste Storage Facility.   (See Table 3, Appendix
          I for List).

     d.    Provide  sufficient   flushing so  that:    a)  all
          materials are conveyed to the main discharge lines
          as expeditiously  as possible;  and  b)  only  water
          resides in the "J" or  drum traps to prevent reverse
          passage of sewer gases.

     e.    Pesticides and PCB's  are restricted to levels of 10
          PPM or lower in aqueous vehicles.

     f.    No dioxins or dibenzofurans at any level - zeroI

     g.    No   biotoxins  or   malodorous   materials   (like
          mercaptans, some amines) - zero!

     h.    Acids   and   bases    may   be   discharged   after
          neutralization  to  MSD's pH limits,  6-10.    (See
          procedures below).

     i.    When sink discharge  is not appropriate,  consign to
          a  proper  Satellite  Storage  vessel  for  ultimate
          transfer to the Waste Storage Facility.

3.    General Neutralization Guidelines and Procedures

     CAUTION!

     Whenever large quantities  of  materials are reacted, a considerable
     amount of heat may be generated.   While this heat may not be
     a problem in test  tube quantities, the heat  build-up  can be
     dangerous with larger quantities, creating an acute hazard.

     a.    Perform  the neutralization  in  a  well-ventilated
          hood and behind a safety shield.
                                   13

-------
b.  Keep the containers cool (usually in an ice solution or surrounded by
    ice).

c.  Wear an apron, goggles, and a face shield (not just safety glasses since
    they do not provide sufficient splash protection) and  gloves.

d.  Slowly neutralize the material so it can be poured into the sink with
    additional amounts of water.

    Procedures tor Acid-Base  Neutralization

e.  Acid Neutralization

    Add the acid  to a large volume of an ice-water solution of sodium
    carbonate  (soda  ash), slaked  lime  or 6M  sodium  hydroxide (for
    concentrated acids).   When the  pH  is above 5.0,  dispose  of  the
    solution into the sewer system with substantial flushing.  If more than
    a few gallons are involved, the pH should  be closer to 7.

 f.  Base Neutralization

     Begin with the base in a large vessel at a concentration of 6M  or less.
    Slowly add a 1M solution of HCL until the pH reaches 10.0  or less.
     Dispose of the neutralized mixture with substantial flushing.
                            14

B.  Commercial Disposal of Toxic and  Hazardous Chemicals

    1.   Rationale and Background

        The chemical operations at Cincinnati can be divided into laboratory scale
        experiments and pilot plant scale  studies.   Pilot  plant studies usually
        generate wastes in larger quantities and may require special permits since
        the operation may not  qualify as a  small generator. The procedures
        described in this manual are primarily for the laboratory scale studies and
        may not  be  applicable to  pilot plant studies. Toxic and  hazardous
        laboratory chemicals are managed in several ways: sink disposal, recycling,
        recovery,  or through commercial disposers.

        The allowable emissions of chemicals from laboratories differ considerably
        from  the allowable emissions  for infectious agents.  Emissions of low
        concentrations or small quantities of chemicals and radioactive materials
        are allowed, but infectious or pathogenic agents must be totally destroyed
        before disposal.  The rationale for this approach is based on the disease
        promoting   potential of biological  materials  and the  essential  non-
        availability  of devices to  contain  biological  materials. It is virtually
        impossible  to handle  chemicals in  a  laboratory and maintain  zero
        emissions.

        A more logical  approach is to establish a goal  of  keeping the emissions
        of chemicals as  low as possible consistent with their hazards, but establish
        achievable standards.  Compliance  or the degree  of compliance can  be
        determined by comparing emissions with the standards.

        The hazardous wastes generated at the EPA-Cincinnati facilities are mostly
         disposed of at  a licensed,  commercial  waste disposal  site, generally  by
         incineration or  burial in a  secure landfill.  The disposal process can  be
         relatively complex because there are a  number of rules and regulations
         which must be followed.  In most cases, the generator (the researcher)
         does not have to be  concerned about how the material is disposed of or
         the  final  shipping   container.    However,   consider  an   interesting
         correspondence in the costs of disposing of nonhazardous and hazardous
         wastes:  nonhazardous wastes can be disposed of for approximately  $10.00
         a drum; however, to prove safety by chemical analysis can  raise the cost
         to that  of disposing  of hazardous wastes, $200.00 to $450.00  per  drum.
         Thus, nonhazardous wastes can end up with  the  same disposal cost as
         hazardous  wastes. There  are several ways to  avoid this problem.  If a
         nonhazardous material is purchased, request a Material Safety Data Sheet
         (MSDS) from the company and if there is an excess of this material,  the
         label can serve as the analytical proof. There are  a  few  other ways to
         reduce  the costs; they all require planning prior to the generation of  the
         wastes.  The  SORD  Office (7969)  can assist you in this.
                                   15

-------
2.   Saietv

    The Occupational Safety and Health Administration (OSHA) requires that
    hazardous chemicals be  handled in a  manner  that  avoids  personnel
    exposure.  This  is best accomplished by  properly packaging  the  waste
    before it leaves the laboratory. No open chemical will  be handled  in the
    storeroom. The same  precautions taken with  new chemicals should  be
    taken with waste chemicals.

3.  Packaging

    The  chemicals must be packaged tor shipment to the disposal site. The
    chemicals will generally go out in a lab pack prepared by the transporter.
    The  wastes  should  be in a  labeled,  non-leaking, sealed and  secure
    container. The generator (owner) of the waste must complete EPA Form
    385  (CIN). These forms are available  from the Collateral Duty  Safety
    Officers or the  SORD Office. The following information is generally
    required:  (See Appendix 7).

    a.   Name of generator, program, room number, date

    b.   "Characterized  By Knowledge" or "Characterized By Analysis"

    c.   Chemical identification tor organics above 1% and inorganics
         above 0.1%; critical metals,  dioxins,  pen's to  10  ppm.  Identity
         generically below these levels.

     d.   Total quantity  of waste (volume or weight),  including percentage
         of major constituents.

     e.   Other information:  e.g. in vials, special hazards

 4.  Storage

     The packaged waste can be taken to the chemical storage room where it
     will be placed on a shelf or in an appropriate drum.  All wastes placed
     in the same drum  must  be compatible.  Selected DOT hazard classes are
     designated as follows:

                 Flammable  liquid
                 Oxidizer
                 Corrosive (liquid)
                    acids
                    bases
                 Peroxides
                 Flammable - dangerous when wet
                               16

-------
   Explosives, etiologic agents and most organic peroxides are not permitted
   in the storeroom.  If an explosive such as picric acid or old ether is found,
   these  materials  must  be  removed by a team of  experts.    Prior
   arrangements can  be  made and dangerous materials can be removed
   within a  few  days by a  commercial  disposer.   The  Cincinnati Fire
   Department Bomb Squad will also remove the material, but are reluctant
   to  do so.   Dangerous materials in the  laboratory can  be avoided  by
   frequent inspections of storage areas and marking the proper disposal date
   on the container.

   The storage area will be inspected  weekly by the principal on-site Safety
   Officer to ensure  the proper storage of virgin and waste  chemicals.

5.  Segregation  of Wastes  by Compatibility

    In some  instances a laboratory may find it convenient to combine  the
    contents of small vials into gallon containers. This is generally acceptable
    if the wastes are  compatible.  Some general guidelines for determining
    compatibility are shown in Appendix 4.  This type of temporary storage in
    the laboratory is often called satellite accumulation.  This  is allowed by
    RCRA under the following conditions:

    a.   The  container is labeled as  "Hazardous  Waste" and the  contents
        described;

    b.  The container is kept closed when not  in use;

    c.   The satellite accumulation of hazardous materials  must not exceed 55-
        gallons, one  liter for "very  hazardous" materials.  AWBERC  has
        established a more restrictive limit  of 5-gallons and only it more than
        5 different  compatibile  groups are present.  The maximum size
        allowed for  a glass container is  1-gallon.   Waste storage in  the
        laboratory should be kept to a minimum.

    d.  The accumulation start date should be noted. The container must be
        taken to the  Center's waste storage area within  72  hours of filling.
                              17

                  PERTINENT MSP REGULATIONS

Section 1515

No person  shall  discharge wastes from garbage  grinders into the
wastewater treatment system except:

(A)  Wastes generated in preparation of food normally consumed on
the  premises, or

(B)  Wastes  of  a specific character whose  discharge after
     grinding is authorized by a  written permit  signed by the
     Director.

All garbage  grinders  shall shred the waste  to  a degree that all
particles  will  be  carried freely  under  normal  flow conditions
prevailing in the public sewer.  Wastes from  garbage grinders used
for grinding plastic, paper products,  inert materials,  or garden
refuse shall not be discharged to the wastewater treatment system.

Section 1516

No person shall discharge any substances directly into a manhole or
other opening in  the wastewater treatment system other than through
an approved building sewer, unless upon written  application to the
Director and payment of the applicable User  charges and fees, the
Director issues a permit  for such direct discharges.

Section 1517   (Revised -  1993)

No person shall discharge wastewater containing  cadmium, chromium,
copper, cyanide (Amenable), cyanide (total),  mercury, nickel, lead
or zinc in concentrations greater than those  listed in Table 1517-
1, wherein concentrations  in  Column (A)  are those  of  composite
samples collected over the daily  period of operation  in proportion
to  flow   so  as   to   produce  a   representative   sample,   and
concentrations in column  (B) are  those of samples collected over a
time interval of not more  than one minute so as  to produce a grab
sample.  However,  if Q,  the daily discharge of a User in gallons
per day, is less than 24,000,  then the allowable  concentration of
any substance listed in Table 1517-1 except Cyanide (Amenable) and
Mercury shall be calculated  by  multiplying the  value  listed in
Table  1517-1 by  24,000/Q, but  in no event shall  an  allowable
concentration exceed three times the listed  value.

Provided,  however,  that   should   circumstances  arise  wherein
Department   personnel,   a   wastewater   treatment  system,   or
receiving water quality, is or  is in danger  of,  being adversely
affected by  wastewater  discharges containing  the substances set
forth in Table 1517-1,  the Director shall have  the authority to
impose effluent limitations more stringent than those set forth in
Table  1517-1 to  the  extent necessary  to eliminate the adverse
impact.

As  its  initial action to enforce  the limits  set forth in Table
1517-1 the Department shall  require the incorporation into the
User's  Wastewater  Discharge  Permit of  a  compliance schedule
developed after notice to and consultation with the permittee and
taking   into  consideration  practical   equipment  delivery  and
construction completion times.

Industries subject to National Categorical Pretreatment Standards
shall comply with the provisions of  Section  1528 in cases where
said provisions are more stringent  than those  of Section 1517.
Otherwise,   all   Users,   including   those  subject  to  National
Categorical   Pretreatment   Standards,  shall  comply   with  the
provisions of  Section 1517.

    interference with  the proper operation of,  a wastewater treatment works.

(E) Any water or wastes that contain phenols  in excess of 0.50 mg/l as determined
    by analysis of a grab sample. This limit may be modified  by the Director if the
    aggregate of contributions throughout the  Metropolitan areas of service  creates
    treatment difficulties, or produces wastewater treatment plant effluent  discharges
    to receiving waters which may be  prohibited, or it experience shows that  higher
    concentrations may be successfully treated  without adverse impact on employees,
    plant and equipment, treatment processes, or receiving water quality.

 (F) Any waste  or wastewater with pH values outside the range  of 6 to 10 standard
    units, which  because of its acid or alkaline properties causes or may cause damage

    calendar  days the average  of the maximum values tor five consecutive  monitoring
    days exceeds 300 ppm (v/v).

    NOTE: For purposes of this subpart (H),  methane (CH,) is not considered an
           organic substance.

Section 1519

No person shall increase the  use of process water or in any other  way  attempt to
dilute a discharge as a partial or complete substitute tor adequate treatment to achieve
compliance with any local or  national discharge standard.

Section 1520

Plans, specifications and any other pertinent information relating to pretreatment or
control facilities shall be submitted for the approval of the Department in advance of
construction, or for existing facilities upon request. Failure to make a  timely submittal
shall be grounds for revocation of or refusal to issue or renew a wastewater discharge
permit.

Section  1521

 Approval of existing or proposed pretreatment or control facilities or equipment by
 the Department does not, in  any way, guarantee that  the facilities or equipment wifl
 function  in   the  manner described  by  their   owner,  designer,  constructor  or
 manufacturer; nor shall  it relieve any person of the  responsibility  of enlarging or
 otherwise modifying such facilities to accomplish the intended purpose of pretreatment

              APPENDIX 3.  Classification of Hazardous Wastes

One of the major decisions which must he made is whether a material is a hazardous
substance.   Guidelines  are  provided in  this section to help you identify hazardous
materials.  The  AWBERC considers materials 'hazardous' if the material would he
considered hazardous by RCRA.  RCRA considers a material hazardous if:

1.  It is listed in RCRA Regulations Subpart D, 261, 3()tf, and it is not excluded under
    261.4(b).  The  exclusions are  domestic  sewage,  household waste,  agricultural
    products that are returned to the soil  as  fertilizers, fossil fuel  combustion waste
    (ash), and samples collected for the purpose of testing to determine characteristics
    or composition.

2.  If  it  exhibits any of the characteristics  of  a hazardous waste  including:

    a.   Ignitability:

         i.  Liquids  having a flash point below 60" C. Aqueous solutions containing less
            than 24% alcohol by volume are  excluded.

        ii.   Non-liquids liable to cause fires through friction, absorption of moisture,
            spontaneous chemical change or  retained heat, and  liable, when ignited,
            to burn so vigorously and persistently as to create a hazard.

        iii.  Ignitable compressed  gases.

        iv.  Oxidizers as defined in 49 CFR 173.151:  A substance such as a  chlorate,
            permanganate, inorganic peroxide, or nitrate that yields oxygen readily to
            stimulate the combustion of organic matter.

                                      29

-------
     Corrosivity
     i.   It is aqueous  and has a pH  2.0  or below, or  12.5 and
          above.

     ii.  It is liquid and corrodes steel of certain specifications
          at a particular rate under controlled conditions.  (See
          CFR 40,  261.22)

c.   Reactivity

     i.   Wastes that readily undergo violent chemical change.

     ii.  Wastes that  react violently with  or from  potentially
          explosive mixtures with water.

     iii. Wastes that generate toxic fumes in  a quantity sufficient
          to present a danger to human health  or  the environment
          when mixed with water or,  in the case of  cyanide  or
          sulfide-bearing wastes, when exposed  to a pH between 2.0
          and 12.5.

     iv.  Wastes that explode when subjected to  a strong initiating
          force,  explode at normal temperatures and pressures,  or
          come  within   the  DOT   classifications  of  forbidden
          explosives.

     v.   Materials with these characteristics, but not listed in
          one of the tables, are given the EPA number D003.

d.   Exceeds the  limits defined  by the Toxicity Characteristic
     Leaching  Procedure (TCLP).  The maximum concentrations are:

         Subpari A—General

§ 261.1   Purpose and .scope.
  (a)  This part  identifies those  solid
wastes which are subject  to regulation
as hazardous  wastes under  parts 262
through 265, 268, and  parts  270, 271,
and 124 of this chapter and which are
subject  to   the   notification  require-
ments of section 3010 of RCRA.  In
this part:
  (1)  Subpart A defines the terms
"solid  waste"  and "hazardous waste",
identifies those  wastes which are ex-
cluded  from  regulation  under  parts
262 through 266, 268 and 270 and es-
tablishes special management require-
ments for hazardous waste produced
by conditionally exempt small quanti-
ty generators and  hazardous waste
which is recycled.
  (2) Subpart B  sets forth the criteria
used by EPA  to identify characteris-
tics of hazardous waste and to list par-
ticular hazardous wastes.
  (3) Subpart  C  identifies characteris-
tics of hazardous waste.
  (4)  Subpart  D lists particular  haz-
ardous wastes.
  (b)(l) The definition of solid waste
contained in this part applies only to
wastes that also  are hazardous for pur-
poses of the regulations implementing
subtitle C of  RCRA. For example,  it
does not  apply  to materials  (such as
non-hazardous scrap,  paper,  textiles,
or rubber) that are not otherwise haz-
ardous wastes  and that are recycled.
  (2) This part identifies  only some of
the materials  which are solid wastes
and  hazardous wastes  under  sections
3007, 3013, and 7003  of RCRA. A mate-
rial  which  is  not defined as a  solid

 part, is still a solid waste and a hazard-
 ous waste for purposes of  these  sec-
 tions if:
  (i)  In the  case of sections 3007  and
 3013, EPA has reason to  believe that
 the material  may  be  a  solid  waste
 within  the meaning of section 1004(27)
 of  RCRA  and a  hazardous  waste
 within  the meaning of section 1004(5)
 of RCRA; or
  (ii) In the case of section 7003,  the
 statutory elements are established.
  (c)  For  the purposes of  §§ 261.2  and
 261.6:
  (DA  "spent  material" is any materi-
 al that has been used and as a  result
 of contamination can no longer serve
 the purpose for which it was produced
 without processing;
  (2)  "Sludge" has the same meaning
 used in  § 260.10 of this chapter;
  (3) A  "by-product" is 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. Examples are process residues
 such  as slags  or distillation  column
 bottoms. The term does not include a
 co-product that  is produced for  the
 general public's use and is ordinarily
 used in the form it is  produced by  the
 process.
  (4) A  material is "reclaimed" if it is
 processed to  recover a usable product,
 or if  it is regenerated.  Examples  are
 recovery of lead values from spent bat-
 teries and regeneration of spent  sol-
 vents.
  (5) A  material is "used or reused" if
 it is either:
  (i) Employed as  an ingredient  (in-
 cluding  use  as  an intermediate)  in an
 industrial process to make a product
(for   example,  distillation  bottoms
 from  one  process used as feedstock in
another process). However, a material
 will not satisfy this  condition if dis-
 tinct  components of the material  are
recovered as separate end products (as
when   metals   are  recovered   from
metal-containing secondary materials);
or
  (ii)  Employed in a  particular  func-
tion or application as an effective sub-
stitute for a commercial product (for
example,  spent pickle liquor used  as
phosphorous precipitant  and sludge
conditioner in wastewater treatment).
          40 CFR Ch. I (7-1-92 Edition)

   (6) "Scrap metal"  is bits and pieces
 of metal  parts  (e.g.,) bars,  turnings,
 rods, sheets, wire) or metal pieces that
 may be combined together with bolts
 or soldering (e.g., radiators, scrap auto-
 mobiles,   railroad  box  cars),  which
 when worn or superfluous can be recy-
 cled.
   (7) A material is  "recycled" if it  is
 used, reused, or reclaimed.
   (8) A material is "accumulated spec-
 ulatively" if it is accumulated before
 being recycled. A material is  not accu-
 mulated speculatively, however, if the
 person accumulating it can show that
 the material is potentially recyclable
 and has a feasible means of being recy-
 cled; and that—during the  calendar
 year (commencing on January 1)—the
 amount of material that is recycled, or
 transferred to a different site for recy-
 cling, equals at least 75 percent by
 weight or volume of  the  amount of
 that material accumulated at the be-
 ginning of the period. In  calculating
 the percentage of turnover, the 75 per-
 cent  requirement is  to be applied to
 each material  of the same type (e.g.,
 slags from a single smelting  process)
 that  is recycled in the same  way (i.e.,
 from which the same material is recov-
 ered or that is used in the same way).
 Materials  accumulating in units that
 would  jȣ  exempt   from  regulation
.under § 261.4(c) are not be included in
 making  the  calculation.  (Materials
 that  are  already  defined  as solid
 wastes  also are not to be included in
 making the calculation.) Materials are
 no longer in this category once they
 are removed from accumulation for re-
 cycling, however.

 §261.2  Definition of solid waste.
  (a)(l) A  solid waste is any discarded
 material  that  is  not excluded  by
 § 261.4(a) or that is  not excluded by
 variance granted under §§260.30 and
 260.31.
  (2) A  discarded material is any mate-
 rial which is:
  (i) Abandoned,  as explained in para-
 graph (b) of this section; or
Environmental Protection Agency

  (ii)  Recycled, as  explained  in  para-
graph (c) of this section; or
  (iii)  Considered  inherently waste-
like, as explained in paragraph (d) of
this section.
  (b)  Materials are solid waste if they
are abandoned by being:
  (1) Disposed of; or
  (2) Burned or incinerated; or
  (3)  Accumulated, stored,  or treated
(but not recycled) before or in lieu of
being abandoned by being disposed of,
burned, or incinerated.
  (c) Materials are solid wastes if they
are recycled—or  accumulated, stored.
or treated before recycling—as speci-
fied in  paragraphs (c)(l) through (4)
of this section.
  (1)  Used in a  manner constituting
disposal, (i) Materials noted with a "*"
in Column 1 of Table I are solid wastes
when they are:
  (A) Applied  to or placed on  the land
in a manner that constitutes  disposal;
or
  (B) Used  to produce  products that
are applied to or  placed on the land or
                              §261.2

are otherwise  contained in products
that are applied to or placed  on the
land (in which  cases the product itself
remains a solid waste).
  (ii)  However, commercial chemical
products listed  in § 261.33 are not solid
wastes if they are applied to the land
and that  is their ordinary manner of
use.
  (2) Burning for energy recovery, (i)
Materials noted with a "*" in column 2
of Table 1 are  solid wastes when they
are:
  (A) Burned to recover energy;
  (B)  Used to  produce a fuel or are
otherwise contained in fuels (in which
cases  the  fuel itself remains  a solid
waste).
  (ii)  However, commercial chemical
products listed  in § 261.33 are not solid
wastes if they are themselves fuels.
  (3) Reclaimed. Materials noted with
a "*" in column 3 of Table  1 are solid
wastes when reclaimed.
  (4) Accumulated speculatively. Mate-
rials noted with a  "•" in column  4 of
Table 1 are solid wastes when accumu-
lated speculatively.

F022, F023. F026, and F028.
  (2)  Secondary  materials fed  to a
halogen acid furnace that exhibit a
characteristic of  a hazardous  waste or
are listed as a hazardous waste as de-
fined in subparts C  or D of this part,
except for brominated material that
meets the following criteria:
  (i) The material must contain a bro-
mine concentration of at least 45%;
and
  (ii) The material must contain less
than a total  of  1%  of  toxic  organic
compounds  listed  in  appendix  VIII;
and
  (iii) The material is processed con-
tinually  on-slte in the  halogen acid
furnace  via  direct conveyance (hard
piping).
                                                                                   35

§261.3

  (3) The Administrator will use the
following criteria to add wastes to that
list:
  (i)(A)  The materials  are ordinarily
disposed of, burned, or incinerated; or
  (B) The materials contain toxic con-
stituents listed  in appendix VIII of
part 261 and these constituents are
not ordinarily found in raw  materials
or products for  which the  materials
substitute (or are found in  raw materi-
als  or products  in smaller concentra-
tions) and  are  not  used or reused
during the recycling process; and
  (ii) The material  may  pose a sub-
stantial hazard to human  health and
the environment when recycled.
  (e) Materials that are not solid waste
when recycled.  (1) Materials are not
solid wastes when they can be shown
to be recycled by being:
  (i) Used or reused as ingredients in
an industrial process to make a prod-
uct,  provided the  materials  are not
being reclaimed; or
  (ii) Used or reused as effective sub-
stitutes  for commercial products; or
  (iii) Returned to the original process
from which they are generated, with-
out first being reclaimed. The material
must be returned as a substitute for
raw material feedstock, and  the  proc-
ess must use raw materials  as principal
feedstocks.
  (2) The following materials are solid
wastes,  even if the recycling involves
use,  reuse,  or return to the original
process  (described in paragraphs (e)(l)
(i) through (iii) of this section):
  (i) Materials used in a manner con-
stituting disposal, or used  to produce
products that are applied to  the  land;
or
  (ii) Materials burned  for energy re-
covery,  used to produce a fuel, or con-
tained in fuels; or
  (iii) Materials accumulated specula-
tively; or
  (iv) Materials  listed  in paragraph
(d)(l) of this section.
  (f) Documentation of  claims  that
materials  are not solid wastes or are
conditionally exempt from regulation.
Respondents in actions to enforce reg-
ulations implementing  subtitle  C of
RCRA who  raise a claim that a certain
material is not a solid waste,  or is con-
ditionally  exempt  from  regulation,
must demonstrate  that   there  is  a
         40 CFR Ch. I (7-1-92 Edition)

known market or disposition for the
material,  and  that  they  meet  the
terms of the exclusion or exemption.
In doing so, they must provide appro-
priate  documentation (such  as con-
tracts showing that a second person
uses the material as an ingredient in a
production  process)  to  demonstrate
that the material is not a waste, or is
exempt from  regulation.  In addition,
owners or operators of facilities claim-
ing that they  actually are  recycling
materials  must show  that they have
the necessary equipment to do so.

§ 261.:!  Definition of hazardous waste.
  (a)  A  solid  waste,  as  defined  in
§ 261.2, is a hazardous waste if:
  (1) It is not excluded from  regula-
tion as  a  hazardous waste  under
§ 261.4(b); and
  (2) It meets any of the following cri-
teria:
  (i) It exhibits any of  the characteris-
tics of hazardous  waste  identified in
subpart C except that any mixture of
a waste from the extraction, beneficia-
tion, and processing of ores and miner-
als excluded under §261.4
-------
§261.3

hazardous waste when any of the fol-
lowing events occur:
  (1) In  the case of  a waste listed in
subpart D of this part, when the waste
first meets the listing description set
forth in subpart D of this part.
  (2) In the case of a mixture of solid
waste and one or more listed hazard-
ous wastes, when  a  hazardous  waste
listed in subpart D is  first added to the
solid waste.
  (3) In  the case of  any other  waste
(including a waste mixture), when the
waste exhibits  any of the characteris-
tics  identified  in subpart  C  of this
part.
  (c) Unless and until it meets the cri-
teria of paragraph (d) of this section:
  (DA hazardous waste will remain a
hazardous waste.
  (2)(i) Except as otherwise  provided
in paragraph (c)(2)(ii) of this section,
any  solid  waste generated  from  the
treatment,  storage,  or  disposal  of  a
hazardous waste, including any sludge,
spill residue,  ash,   emission  control
dust, or  leachate (but  not including
precipitation run-off) is a hazardous
waste. (However, materials that are re-
claimed from solid wastes and that are
used beneficially are  not solid wastes
and  hence  are  not hazardous wastes
under  this provision unless  the re-
claimed material is burned for energy
recovery or used  in  a manner consti-
tuting disposal.)
  (ii) The following  solid wastes are
not hazardous even  though they are
generated  from  the   treatment,  stor-
age, or disposal of a  hazardous waste,
unless they exhibit one or more of the
characteristics of hazardous waste:
  (A) Waste pickle liquor sludge gener-
ated by   lime  stabilization  of  spent
pickle liquor from the iron and  steel
industry  (SIC Codes 331  and 332).
  (B) Waste from burning any of the
materials exempted  from  regulation
by § 261.6(a)(3)(v) through (viii).
  (C) Nonwastewater residues, such as
slag, resulting from high temperature
metals recovery (HTMR) processing of
K061 waste,  in  units  identified  as
rotary  kilns,  flame  reactors,  electric
furnaces,  plasma arc  furnaces, slag re-
actors, rotary hearth furnace/electric
furnace  combinations  or   industrial
furnaces  (as  defined  in  40   CPR
260.10(6), (7). and (12), that  are  dis-
         40 CFR Ch. I (7-1-92 Edition)

posed  in subtitle  D  units, provided
that these residues meet  the  generic
exclusion levels identified below for all
constituents, and exhibit no character-
istics of hazardous waste. Testing re-
quirements must be incorporated in a
facility's waste analysis plan or a gen-
erator's self-implementing waste anal-
ysis  plan;  at a  minimum, composite
samples of residues must be collected
and  analyzed quarterly  and/or  when
the  process  or  operation  generating
the waste changes. The generic exclu-
sion  levels are:
           Constituent

Arsenic	
Barium	
Beryllium	
Cadmium	
Chromium (total)..

  For each shipment of K061 HTMR
residues  sent  to subtitle D unit that
meets the generic exclusion levels  for
all constituents, and  does not exhibit
any characteristic, a notification and
certification must be sent to  the  ap-
propriate Regional Administrator  (or
delegated representative) or State  au-
thorized  to implement part   268  re-
quirements. The notification  must in-
clude the  following  information:  (1}
The name and address  of the subtitle
D unit receiving  the waste shipment;
(2) the EPA hazardous waste  number
and  treatability group at the initial
point  of generation;  (3)  treatment
standards applicable  to the waste  at
the intital point  of  generation. The
certification must be  signed by an  au-
thorized  representative  and must state
as follows: "I certify under penalty of
law that the  generic exclusion levels
for all  constituents  have  been  met
without  impermissible  dilution  and
that no  characteristic  of  hazardous
waste is  exhibited. I am aware that
Environmental Protection Agency

there are significant penalties for sub-
mitting a false certification, including
the possibility  of fine and  imprison-
ment."
  (d)  Any solid waste described  in
paragraph (c) of this  section is not a
hazardous waste if it meets the follow-
ing criteria:
  (1) In the case of any solid waste, it
does not exhibit any of the character-
istics  of hazardous waste identified in
subpart  C  of  this  part.  (However,
wastes that exhibit a characteristic at
the point of generation may  still  be
subject to the  requirements of  part
268, even if they no longer exhibit a
characteristic at the point of land dis-
posal.)
  (2) In the case of a waste which is a
listed waste  under subpart D of this
part, contains a waste listed under sub-
part D of this part or is derived from a
waste listed in subpart D of this part,
it also has been excluded from  para-
graph  (c)  of   this  section  under
§§ 260.20 and 260.22 of this chapter.
  (e)  Sunset  provision.  Paragraphs
(a)(2)(iv)  and (c)(2)(i) of  this section
shall  remain in effect only until April
28, 1993.

system.
  (2)  Industrial wastewater discharges
that  are point source discharges sub-
ject to regulation under section 402 of
the Clean Water Act, as amended.

[Comment:  This exclusion applies only to
the actual point source discharge. It does
not exclude industrial  wastewaters  while
they are being collected, stored or treated
before discharge, nor does it exclude sludges

 claimed and  returned  to  the original
 process  or processes in  which  they
 were generated where they are reused
 in the production process provided:
   (i) Only tank storage is involved, and
 the entire process through completion
 of reclamation is  closed by being  en-
 tirely connected with  pipes  or other
 comparable enclosed means of convey-
 ance;
   (ii) Reclamation does  not  involve

are recycled to coke ovens,  to the tar
recovery process  as  a  feedstock  to
produce  coal  tar  or  are mixed  with
coal tar prior to the tar's sale or refin-
ing. This exclusion is conditioned  on
there being no land disposal  of the
wastes from the point they  are gener-
ated to  the point they are recycled to
coke ovens or  the  tar refining process.
  (11) Nonwastewater splash condens-
er dross residue from the treatment of

posed, recovered  (e.g., refuse-derived
fuel)  or reused.  "Household  waste"
means  any material  (including gar-
bage, trash and  sanitary  wastes  in
septic tanks) derived from households
(including  single  and  multiple  resi-
dences,   hotels and  motels,   bunk-
houses, ranger stations, crew quarters,
campgrounds,  picnic grounds and day-
use recreation areas). A resource  re-
covery  facility managing  municipal
solid waste shall not be  deemed to be
treating, storing, disposing of, or oth-
erwise managing hazardous  wastes for
the purposes of regulation  under this
subtitle, if such facility:
  (i) Receives and burns only
  (A) Household  waste (from  single
and multiple dwellings, hotels, motels,
and other residential sources) and
  (B) Solid waste  from commercial or
industrial sources  that does not con-
tain hazardous waste; and
  (ii) Such facility does not accept haz-
ardous wastes and the owner or opera-
tor of  such  facility has  established
contractual requirements or other ap-
propriate notification  or  inspection
procedures to  assure  that  hazardous
wastes are not received at or burned in
such facility.
  (2) Solid wastes  generated by any of
the following  and which are returned
to the soils as  fertilizers:
  (i) The growing and  harvesting of
agricultural crops.
  (ii) The raising of animals, including
animal manures.
         40 CFR Ch. I (7-1-92 Edition)

  (3) Mining overburden  returned to
the mine site.
  (4) Fly ash waste, bottom ash waste,
slag waste, and flue gas emission con-
trol waste,  generated  primarily from
the combusion of  coal or other fossil
fuels, except as provided  by  § 266.112
of this chapter for facilities that burn
or process hazardous waste.
  (5) Drilling fluids, produced waters,
and other wastes  associated  with  the
exploration, development, or produc-
tion of  crude  oil,  natural gas or geo-
thermal energy.
  (6 Hi) Wastes which fail the test for
the Toxicity  Characteristic because
chromium is present or are  listed in
subpart D due to the presence of chro-
mium, which do not fail  the test for
the Toxicity  Characteristic  for  any
other constituent or are not listed  due
to the presence of any other constitu-
ent, and which do  not  fail the test for
any other characteristic, if it is shown
by a waste generator or by waste gen-
erators that:
  (A)  The chromium in the waste is
exclusively (or nearly  exclusively) tri-
valent chromium; and
  (B)  The waste is generated from an
industrial process which uses trivalent
chromium exlcusively (or nearly exclu-
sively) and the process does not, gener-
ate hexavalent chromium; and
  (C)  The waste is typically and  fre-
quently managed in non-oxidizing en-
vironments.
  (ii)  Specific  wastes which meet  the
standard  in paragraphs  (b)(6)(i)(A),
(B) and (C)  (so long as  they do not fail
the test for the  charactristic  of EP
toxicity, and do not fail  the test for
any other characteristic) are:
  (A)  Chrome (blue) trimmings gener-
ated by the following subcategories of
the leather tanning and  finishing in-
dustry:  hair pulp/chrome tan/retan/
wet finish; hair  save/chrome  tan/
retan/wet finish; retan/wet finish; no
beamhouse:   through-the-blue;    and
shearling.
  (B)  Chrome  (blue) shavings generat-
ed  by the following subcategories of
the leather tanning and  finishing in-

Subpart  B—Criteria   for Identifying
    the  Characteristics of Hazardous
    Waste and for Listing Hazardous
    Waste

§261.10  Criteria  for identifying the char-
   acteristics of hazardous waste.
  (a) The Administrator shall identify
and define a characteristic of hazard-
ous waste in subpart C only upon de-
termining that:
  (DA solid waste  that  exhibits  the
characteristic may:
  (i) Cause,  or significantly contribute
to, an  increase in mortality  or  an in-
crease  in serious irreversible, or inca-
pacitating reversible, illness; or
  (ii) Pose a substantial present or po-
tential hazard to human health  or the
environment when  it is improperly
treated, stored, transported, disposed
of or otherwise managed;  and
  (2) The characteristic can be:
  (i)  Measured by an  available  stand-
ardized test method which  is reason-
ably  within the capability of genera-
tors  of solid waste  or private  sector
         40 CFR Ch. I (7-1-92 Edition)

laboratories that are available to serve
generators of solid waste; or
  (ii) Reasonably detected by genera-
tors  of  solid  waste  through  their
knowledge of their waste.

§261.11  Criteria  for  listing  hazardous
    waste.

  (a) The  Administrator shall  list a
solid waste as a hazardous waste only
upon determining that the solid waste
meets one of the following criteria:
  (1) It exhibits any of the character-
istics of hazardous  waste identified in
subpart C.
  (2) It has been found  to be fatal to
humans in low doses or, in the absence
of data on  human toxicity, it has been
shown in studies to have an oral LD 50
toxicity (rat) of less than  50 milli-
grams per  kilogram, an inhalation  LC
50 toxicity (rat) of less than 2 milli-
grams per liter, or a dermal LD 50 tox-
icity  (rabbit) of less than 200 milli-
grams per kilogram or is otherwise ca-
pable of causing or significantly con-
tributing to an increase in serious irre-
versible,  or incapacitating  reversible,
illness.  (Waste  listed  in  accordance
with these criteria  will be designated
Acute Hazardous Waste.)
  (3) It contains any of the toxic con-
stituents listed in appendix VIII and,
after considering the following factors,
the Administrator concludes that the
waste is capable of posing a substan-
tial  present  or potential hazard   to
human  health  or the environment
when  improperly   treated,   stored,
transported or  disposed of, or other-
wise managed:
  (i) The  nature of the toxicity pre-
sented by the constituent.
  (ii) The concentration of the constit-
uent in the waste.
  (iii) The potential of the constituent
or any toxic degradation  product  of
the  constituent  to  migrate from the
waste into  the environment under the
types of improper management consid-
ered in paragraph  (a)(3)(vii) of this
section.
  (iv) The persistence of the constitu-
ent or any toxic degradation product
of the constituent.
  (v) The potential  for the constituent
or any toxic degradation  product  of
the  constituent  to  degrade into non-
Environmental Protection Agency

harmful  constituents and  the  rate of
degradation.
  (vi) The degree to which  the  constit-
uent or  any degradation  product of
the constituent bioaccumulates in eco-
systems.
  (vii) The plausible types of improper
management to which the  waste could
be subjected.
  (viii) The  quantities of  the waste
generated  at  individual  generation
sites or on a regional or national basis.
  (ix) The nature and severity of the
human  health  and   environmental
damage that has occurred as a result
of  the   improper  management  of
wastes containing the constituent.
  (x)  Action taken by other  govern-
mental agencies  or  regulatory  pro-
grams  based  on the health or environ-
mental hazard posed by the waste or
waste constituent.
  (xi) Such other factors as may be ap-
propriate.
Substances will be listed on appendix
VIH only if  they  have been shown in
scientific studies to  have toxic, carci-
nogenic,  mutagenic or teratogenic ef-
fects on humans or other life forms.
  (Wastes listed   in accordance with
these criteria will be designated Toxic
wastes.)
  (b) The Administrator may list class-
es or types of solid waste as hazardous
waste  if  he has reason to believe that
individual wastes, within the  class or
type of waste,  typically or frequently
are hazardous under the definition of
hazardous  waste  found  in  section
1004(5) of the Act.
  (c) The Administrator will  use the
criteria for listing specified in this sec-
tion to establish  the  exclusion limits
referred  to in § 261.5(c).

forth the generator's responsibility to deter-
mine whether his waste  exhibits one or
more of the characteristics identified in this
subpart]
  (b) A hazardous waste which is iden-
tified by a characteristic in this sub-
part is assigned every EPA  Hazardous
Waste Number that is applicable as set
forth in  this  subparU This number
must be used  in complying with the
notification  requirements  of section
3010 of the Act and all applicable rec-
ordkeeping   and  reporting  require-
ments under parts  262 through 265,
268, and 270 of this chapter.
  (c) For purposes of this subpart, the
Administrator  will consider a sample
obtained using any  of  the  applicable
sampling  methods specified in appen-
dix I to  be  a  representative sample
within the meaning of part  260 of this

§ 261.23  Characteristic of reactivity.
  (a) A solid waste exhibits the charac-
teristic of reactivity if a representative
sample of the waste has any of the fol-
lowing properties:
  (1) It is normally unstable and read-
ily undergoes violent change without
detonating.
  (2) It reacts violently with water.
  (3)  It  forms  potentially  explosive
mixtures with water.
  (4) When mixed with water, it gener-
ates  toxic gases,  vapors or fumes in a
quantity sufficient to present a danger
to human health or the environment.
  (5) It is a cyanide  or sulfide bearing
waste which, when exposed to pH con-
ditions between 2 and 12.5, can gener-
ate toxic gases, vapors or fumes in a
quantity sufficient to present a danger
to human health or the environment.
  (6) It is capable of detonation or ex-
plosive reaction if it is subjected to a
strong initiating  source or if heated
under confinement.
  (7) It is readily capable of detona-
tion or explosive decomposition or re-
action at standard  temperature and
pressure.
  (8) It is a forbidden explosive as de-
fined in  49  CFR  173.51, or a Class A
explosive as defined in 49 CFR 173.53
or a Class B explosive as defined in 49
CFR 173.88.

§ 261.24  Toxicity characteristic.
  (a) A solid waste exhibits the charac-
teristic  of toxicity if, using  the test
methods described in  appendix  II or
equivalent methods approved by the
Administrator  under the procedures
set forth in  §§ 260.20 and 260.21, the
extract from a representative sample
of the waste contains any of the con-
taminants listed  in table 1 at the con-
centration equal to or greater than the
respective value  given in that table.
Where the waste  contains less than 0.5
percent  filterable solids, the waste
itself, after filtering using the method-
ology outlined  in appendix II, is con-
sidered  to be the extract for the pur-
pose of this section.
  (b) A solid waste  that exhibits the
characteristic of toxicity has the EPA
Hazardous Waste Number specified in
Table I which corresponds to the toxic
contaminant causing it  to be hazard-
ous.

  (b) Listing Specific Definitions: (1) For the purposes of the F037  and F038 list-
ings, oil/water/solids is defined as oil and/or water and/or solids.
  (2)  (i)  For the  purposes of the F037 and F038 listings, aggressive  biological
treatment units are  defined as units  which employ one  of the following four
treatment methods: activated sludge;  trickling filter; rotating biological contac-
tor for the continuous  accelerated biological oxidation of wastewaters; or  high-
rate aeration. High-rate aeration is  a system of surface impoundments or tanks,
in  which intense mechanical aeration is used to completely mix the wastes, en-
hance biological activity, and (A) the units employs a minimum of 6  hp per mil-
lion gallons of treatment volume; and  either (B) the hydraulic retention time  of
the unit  is  no longer  than  5  days^ or (C)  the hydraulic retention time  is  no
longer than 30 days and the unit does not generate a sludge  that is a hazardous
waste by the Toxicity Characteristic.
  (ii) Generators and treatment, storage and disposal facilities have  the burden
of  proving  that their sludges are  exempt  from listing as  F037 and F038 wastes
under this  definition. Generators and  treatment, storage  and disposal facilities
must maintain,  in their operating or other onsite records, documents and data
sufficient to prove that: (A) the unit is an  aggressive biological treatment unit  as
defined in this subsection; and  (B)  the sludges sought to be exempted from the
definitions of  F037 and/or  F038  were  actually generated  in the aggressive bio-
logical treatment  unit.
  (3) (i) For the purposes of the F037 listing, sludges  are considered to be gener-
ated at the  moment  of deposition in the unit, where deposition  is defined as  at
least a temporary cessation  of lateral particle movement.
  (ii) For the purposes of the F038 listing,
  (A) sludges are considered to  be generated at the moment of deposition in the
unit, where deposition is defined as at least a temporary cessation of  lateral par-
ticle movement and
  (B) floats are considered  to  be generated at the moment they are formed  in
the top of the unit.

considers the residue to be intended for dis-
card, and thus, a hazardous waste. An exam-
ple of a legitimate  re-use of the residue
would be where the residue remains in the
container and the container is used to hold
the same commercial chemical  product or
manufacturing chemical intermediate it pre-
viously held. An example of the discard of
the residue would be where the drum is sent
to a drum reconditioner who reconditions
the drum but discards the residue.}

  (d) Any residue or contaminated soil,
water or  other debris  resulting from
the cleanup of a spill into or on any
land or  water  of  any  commercial
chemical  product or  manufacturing
chemical  intermediate having the ge-
neric name listed in paragraph (e) or
(f) of this section, or any residue or
contaminated  soil,  water  or  other
debris resulting from the cleanup of a
spill, into or on  any land  or water, of
any off-specification chemical  product
and manufacturing chemical interme-
diate which, if  it met specifications,
would have the generic name listed in
paragraph (e) or (f) of this section.

{.Comment- The phrase "commercial chemi-
cal product or manufacturing chemical in-
termediate having the  generic name listed
in ..."  refers to  a  chemical substance
which is manufactured or formulated for
commercial or  manufacturing  use  which
consists of the commercially pure grade of
         40 CFR Ch. I (7-1-92 Edition)

the chemical,  any technical grades of the
chemical  that are produced or marketed.
and all formulations in which the chemical
is  the  sole active ingredient. It does not
refer to a material, such as a manufacturing
process waste, that contains any of the sub-
stances listed in paragraph (e) or (f). Where
a manufacturing process waste is deemed to
be a hazardous waste  because it contains a
substance listed in paragraph (e) or (f), such
waste will be listed  in  either § 261.31  or
§ 261.32 or will be identified as a hazardous
waste by the characteristics set forth in sub-
part C of this part.]

  (e) The commercial chemical prod-
ucts, manufacturing chemical interme-
diates or off-specification commercial
chemical products  or manufacturing
chemical intermediates referred to  in
paragraphs (a) through (d) of this sec-
tion, are identified as acute hazardous
wastes (H) and are subject to be the
small  quantity  exclusion defined  in
§ 261.5(e).

(.Comment: For the convenience of the  regu-
lated  community  the primary hazardous
properties of these materials have been indi-
cated by the letters T (Toxicity), and R (Re-
activity).  Absence of a letter indicates that
the compound only is listed for acute toxici-
ty.J

                              APPENDIX 4

             INCOMPATIBLE AND UNSTABLE CHEMICALS
Unstable Chemicals

Unstable compounds that are explosive are capable of undergoing violent reactions
which can  be initiated in a number of ways, including dropping of the container.
unscrewing the lid, excess heat, and unknown causes, incompatible chemicals on the
other hand are generally stable compounds, but when mixed together can produce
undesirable reactions.

Explosives  should be segregated from other toxic wastes so that if an explosion occurs
the problems are  not  compounded by the spreading of radioactive or other toxic
materials. Explosives should not be mixed with toxics in the same container, and even
if packaged separately, explosives should  not  be  placed in the same outer container
such as a lab pack.  DOT regulations must be strictly followed as well as the rules
established by the disposer.

Some commercial disposers will accept wastes only if the wastes have been packaged
by their own personnel. This is to ensure that the DOT regulations are met and also
to prevent injury and damage to equipment during incineration. Some disposers will
incinerate  explosives, but only after they  have been greatly diluted with a solvent or
sawdust. The Safety Officer should be notified of explosive materials so that special
precautions  can  be taken.  Explosive material must be treated differently than
incompatible chemicals.

There are a number of explosive compounds which occasionally are  found in  the
laboratory.  A partial list of classes of shock-sensitive compounds includes:

                Acetylenic cpds           Diazo cpds
                Many nitrates             Peroxides
                Perch lorates              Azides
                Picrates
                                     54

-------
Incompatible Chemicals

Incompatible chemicals are capable of reacting with each other if mixed.  The way to
prevent the undesirable reactions from occurring is to keep such chemicals separate from
each other.  Incompatible chemicals can  react with each other:

        1.  Violently
       2.  With the production of substantial heat
       3.  To produce flammable products or
       4.  To produce toxic products

If small quantities of wastes are accumulated in a single container, extreme care must be
taken to ensure that only compatible wastes are placed  in the same  container.  There
are lists  of specific  incompatible  chemicals  available  such as  provided  in PRUDENT
PRACTICES FOR DISPOSAL OF CHEMICALS FROM LABORATORIES,  page  234
which should be consulted prior to mixing waste  chemicals.  Tables 1  and 2 compose a
hazardous waste compatibility chart, which provides a method for determining the effects
of mixing various reactive groups.

Several selected classes of incompatible  chemicals are given below to provide general
guidance:

            Table 2. Rules for Segregating Incompatible Chemicals
The hazards created by the intermingling of chemicals exists not only with wastes, but
also with new materials.  Personnel in storerooms and laboratories should make efforts
to separate chemicals by the class of hazard.  Because of the  number of different
classes of incompatible chemicals, this may be impossible because of space restrictions,
etc.   When incompatible chemicals cannot be entirely separated from each other,
packages  and containers should  be placed in trays  or  bins  to  prevent  mixing if
containers  are broken or dropped during handling. A publication from the Consumer
Product Safety Commission suggests an arrangement for storing chemicals in high
school chemistry laboratories; inquire in the Library or Safety Office.

The following  is a  list of  materials which should  not  be mixed  and if possible
containers with these materials should be  segregated.

SEGREGATION*  OF LABORATORY  CHEMICALS FOR  DISPOSAL AND
STORAGE

 1.  Corrosive Materials

    a.  Acids from bases
    b.  Organic acids from  inorganic acids
    c.  Materials which should be separated from all others

         i.      Bromine
        ii.      Hypochlorite
        iii.     "Corrosive keep dry" materials

 2.  Flammable Liquids

    a.  Flammable and combustible liquids can  be placed together
    b.  Ethers should be packaged alone when  possible
    c.  Tetrahydrofuran and Dioxane  if  greater than  50%  must  be treated   as
        reactives;  if under 50%, treat as combustibles

     *  Segregation means  a physical distance, and a barrier if possible
                                        56

-------
3.   Oxidizers

    a.   Separate organic oxidizers from inorganic oxidizers
    h.   Separate weak oxidizers from strong oxidizers

4.   Poisons

    Most poisons can be packaged together with the exception of;

    a.   TD1/MDI wastes**
    b.   Cyanides
    c.   Sulfides
        ORM-As, ORM-Cs, and ORM-Es,** can be segregated with poisons.  Highly
        toxic materials such as dioxins, etc., are unacceptable

5.  Flammable  Solids

    Flammable  solids may  be placed only with other flammable solids.  "Dangerous
    when wet" compounds  are reactives  and must be handled as such.

6.  Reactive Materials

    Keep away from water and don't overpack together. Reactive classes  include:

    a.  Corrosives such as acetyl  bromide, oxychloride, phosphorous trichloride
    b.  Flammable solids  such  as carbides, hydrides, and pure metal  dusts like zinc,
        calcium, potassium, etc.
    c.  Oxidizers,  Peroxides
    d.  Flammable solids  (air reactive); Phosphorous
    e.  Flammable liquids such as ethers, dioxane, dispersions of reactive metals

 7.  Separate acutely  hazardous   (P-Listed and F020-F028) wastes from  "Plain"
    hazardous.   Acutely hazardous may  be accumulated up to one quart, and "Plain"
    hazarous to 55 gallons: mixtures must  be treated as acutely hazardous. When full.
    there are 3 days to move them to Central  Waste Storage.

The Management of Hazardous Chemical Waste in the Laboratory

                     LABORATORY WASTE MINIMIZATION

1.  Do not purchase large containers of chemicals with a short shelf life.

2.  Determine chemical disposal costs when purchasing new chemicals.

3.  Use micro testing procedures in place of macro procedures wherever possible.

4.  Provide waste conversion procedures as part of the analytical methods.

5.  Preserve chemical and reagent bottle labels to prevent creating a hazardous waste at a later
    date because of an unknown container content.

6.  Exchange unused chemicals with other laboratories so as not to create hazardous wastes.

7.  Itemize all wastes created in the laboratory and determine area where waste reduction may
    take place.

8.  If a large amount  of a particular solvent is used, consider routine distillation tor reuse.

                    LABORATORY WASTE ACCUMULATION

 1.  Develop an accumulation and storage plan for the type of wastes generated.

2.  Train all employees  to  use  the accumulation plan so  not to create additional  waste
    problems.

3.  Design  the accumulation and storage areas to be secure and protected from the weather.

4.  Determine if waste accumulation and storage areas need temperature control.

 5.  Establish satellite  accumulation areas, if appropriate for the laboratory operation.

 6.  Know the rules that apply to the destination of the  wastes and use the proper DOT
    containers to eliminate further waste transfer between  containers.

 7.  Place only compatible wastes in the same container.

 8.  Identify the container contents at all times.

 9.  All storage areas should have secondary containment with curbing and no floor drains to
    prevent any spilled wastes from escaping the area.

10.  Segregate various storage containers according to hazard classes.
                                        59

     PROCEDURE FOR THE COMMERCIAL DISPOSAL OF HAZARDOUS WASTES

                          Procedures for the Owner of the Wastes

In order to meet RCRA and OSHA requirements, waste chemicals which are not suitable tor
disposable via the sink will be removed by a permitted transporter and disposer. The generator
(owner) of excess, out-of-date or waste chemicals should use the following procedure:

1.  Package each chemical in a clean, secure container,  carrying a red "hazard waste" label

2.  Complete the EPA Form-385 (CIN) and bring to Waste Coordinator (WC)

    a.   The Waste Coordinator assigns a log number and retains white copy
    b.   Attach the yellow (second) copy to the container at storage facility
    c.   Retain the pink (third) copy for own records

3.  Transport the wastes to the chemical storage room (dock)

4.  Discuss recycling of unneeded but usable chemicals prior to declaring waste. It unwanted and
    with legible original label, bring  to Waste Coordinator without a 385 Form.  If  unlabeled or
    illegible, identify accurately and bring to Waste Coordinator with 385 Form.

                       Procedures for the  Collateral Duty Safety Officer

 1.  Be sure that all information requested on EPA Form-385 has been submitted.

2.  Be sure each container is clean with a  secure lid.

 3.  Be sure the containers are identified on a label.

 4.   Be sure a responsible person transfers  the waste materials safely to the waste storage area.

                           Procedures tor  the Waste  Control Officer

 1.   Prepare a list of  chemicals (monthly) for recycling.

 2.   Identify any materials which will need special handling  or disposal  procedures.

 3.   Arrange for the chemicals to be picked up within  the allowable storage  period-up to 270 days
     for SQGs who ship wastes more than 200 miles.

 4.   Check packaging, marking, labeling, and placarding.

 5.   Assemble all manifests with attachments in an orderly manner and  retain in a permanent file.
     Mail all apporpriate materials to Region (V for AWBERC) and to state EPA's, it  required.
