-------
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.

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.

-------
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.

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

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.

Section 1518
No person shall discharge or cause to he discharged to the wastewater treatment
system any of the following described substances, materials, waters or wastes:
(A) Any liquid or vapor having a temperature higher than 150 degress Fahrenheit (65
degrees Celsius) or which produces a temperature of 104 degrees Fahrenheit (40
degrees Celsius) or greater in wastewater entering a wastewater treatment plant.
(B) Any water or wastes containing floating oils, fat. or grease or containing more than
50 milligrams per liter of petroleum oil, products of mineral oil origin, or other
nonbiodegradable oils or substances, as determined by analysis of a grab sample.
(C) Any water or wastes containing dissolved gases (such as but not limited to
hydrogen sulfide, sulfur oxides, nitrogen oxides, and ammonia) in concentrations
sufficient to cause poisonous or toxic fumes or wastewater, or a malodorous or
harmful condition.
(D) Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar,
plastics, wood, asphaltic materials, cement or concrete, paunch manure, hair and
fleshings, entrails, lime slurry, lime residues, beer or distillery spent grains,
chemical residues, paint residues, cannery waste bulk solids, or any other solid
or viscous substances, in amounts capable of causing obstruction to flow in, or
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
or injury to equipment, the wastewater treatment system, the wastewater treatment
process, personnel of the Department, members of the public or the Department
to be in violation of any of its NPDES permits.

waste or wastewater are tested using the "Final Procedure Vapor Space Organics"
as published by MSD, the aggregate concentration of organic substances in the
vapor space exceeds 450 ppm (v/v) on any day, or during any 90 consecutive
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.
App. 3

-------
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
waste in this part, or is not a hazard-
ous waste identified or listed in this
34
-------
§261.2
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.

The following materials are solid
wastes when they are recycled in any
manner:
(1) Hazardous Waste Nos. F020, F021
(unless used as an ingredient to make
a product at the site of generation),
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).

§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:

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.

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-

§261.5 Special requirements for hazard-
ous waste generated by conditionally
exempt small quantity generators.
(a) A generator is a conditionally
exempt small quantity generator in a
calendar month if he generates no
more than 100 kilograms of hazardous
waste in that month.
(b) Except for those wastes identi-
fied in paragraphs (e), (f), (g), and (j)
of this section, a conditionally exempt
small quantity generator's hazardous
wastes are not subject to regulation
under parts 262 through 266, 268, and
parts 270 and 124 of this chapter, and
the notification requirements of sec-
tion 3010 of RCRA, provided the gen-
erator complies with the requirements
of paragraphs (f), (g), and (j) of this
section.
(c) Hazardous waste that is not sub-
ject to regulation or that is subject
only to §262.11, §262.12, § 262.40(c>,
and § 262.41 is not included in the
quantity determinations of this part
and parts 262 through 266, 268, and
270 and is not subject to any of the re-
quirements of those parts. Hazardous
waste that is subject to the require-
ments of I 261.6 (b) and (c) and sub-
parts C, D, and F of part 266 is includ-
ed in. the quantity determination of
this part and is subject to the require-
ments of parts 262 through 266 and
270.
(d) In determining the quantity of
hazardous waste generated, a genera-
tor need not include:
(1) Hazardous waste when it is re-
moved from on-site storage; or
(2) Hazardous waste produced by on-
site treatment (including reclamation)
of his hazardous waste, so long as the
40 CFR Ch. I (7-1-92 Edition)
hazardous waste that is treated was
counted once; or
(3) Spent materials that are generat-
ed, reclaimed, and subsequently roused
on-site, so long as such spent materials
have been counted once.
(e) If a generator generates acute
hazardous waste in a calendar month
in quantities greater than set forth
below, all quantities of that acute haz-
ardous waste are subject to full regula-
tion under parts 262 through 266, 268,
and parts 270 and 124 of this chapter,
and the notification requirements of
section 3010 of RCRA:

other debris resulting from the clean-
up of a spill, into or on any land or
water, of any acute hazardous wastes
listed in §§ 261.31, 261.32, or 261.33(e).
[Comment: "Full regulation" means those
regulations applicable to generators of
greater than 1,000 kg of non-acutely hazard-
ous waste in a calendar month.]
(f) In order for acute hazardous
wastes generated by a generator of
acute hazardous wastes in quantities
equal to or less than those set forth in

cumulation of wastes on-site begins for
a conditionally exempt small quantity
generator when the accumulated
wastes exceed 1000 kilograms;
(3) A conditionally exempt small
quantity generator may either treat or
dispose of his hazardous waste in an
on-site facility or ensure delivery to an
off-site treatment, storage or disposal
facility, either of which, if located in

(h) Hazardous waste subject to the
reduced requirements of this section
may be mixed with non-hazardous
waste and remain subject to these re-
duced requirements even though the
resultant mixture exceeds the quanti-
ty limitations identified in this section,
unless the mixture meets any of the
characteristics of hazardous waste
identified in subpart C.
(i) If any person mixes a solid waste
with a hazardous waste that exceeds a
quantity exclusion level of this sec-
tion, the mixture is subject to full reg-
ulation.
(j) If a conditionally exempt small
quantity generator's wastes are mixed

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).

§261.33 Discarded commercial chemical
products, off-specification species, con-
tainer residues, and spill residues
thereof.
The following materials or items are
hazardous wastes if and when they are
discarded or intended to be discarded
as described in § 261.2(a)(2)(i), when
they are mixed with waste oil or used
oil or other material and applied to
the land for dust suppression or road
treatment, when they are otherwise
applied to the land in lieu of their
original intended use or when they are
contained in products that are applied
to the land in lieu of their original in-
tended use, or when, in lieu of their
original intended use, they are pro-
duced for use as (or as a component
of) a fuel, distributed for use as a fuel,
or burned as a fuel.
(a) Any commercial chemical prod-
uct, or manufacturing chemical inter-
mediate having the generic name
listed in paragraph (e) or (f) of this
section.
(b) Any off-specification commercial
chemical product or manufacturing
chemical intermediate which, if it met
specifications, would have the generic
vname listed in paragraph (e) or (f) of
this section.
(c) Any residue remaining in a con-
tainer or in an inner liner removed
from a container that has held any
commercial chemical product or man-
ufacturing chemical intermediate
having the generic name listed in
paragraphs (e) or (f) of this section,
unless the container is empty as de-
fined in § 261.7(b) of this chapter.
[Comment- Unless the residue Is being bene-
ficially used or reused, or legitimately recy-
cled or reclaimed; or being accumulated,
stored, transported or treated prior to such
use, re-use, recycling or reclamation, EPA
47
-------
§261.33
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.

APPENDIX 6
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.

APPENDIX 7
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.
