On-site CERCLA remedial actions must comply with (or waive) requirements of the Resource Conservation and Recovery
Act (RCRA) that are determined to be applicable or relevant and appropriate requirements (ARARs). For RCRA Subtitle C hazardous
waste requirements to be applicable, the CERCLA response action must constitute treatment, storage, transport, or disposal of a
RCRA hazardous waste. Therefore, to determine when these RCRA requirements are applicable or relevant and appropriate, site
managers must understand how to identify whether a CERCLA hazardous substance is a RCRA hazardous waste. This guide
defines RCRA hazardous wastes and describes how to determine when a CERCLA substance is also a RCRA listed or
characteristic hazardous waste. EPA is currently developing rulemakings that may revise the regulatory status of solid
and hazardous wastes, and therefore contaminated environmental media. EPA will publish fact sheets discussing the
applicability of these rulemakings to CERCLA hazardous substances once these rules are finalized.

The determination of whether a waste is a RCRA
hazardous waste should occur as early as possible in the
Superfund process. That is, site managers should begin to make
this determination even prior to the Remedial
Investigation/Feasibility Study (RI/FS) (i.e., during scoping), if
possible. Site managers should keep in mind that in States
where the RCRA program is delegated to the State, more
wastes may be regulated than under Federal requirements. Site
managers should consult Regional RCRA staff in making this
determination.
To determine whether RCRA Subtitle C requirements are
ARARs, site managers must answer the following questions:
(1)	(a) Is the CERCLA material a solid waste? (b) If so, is the
solid waste excluded from regulation under RCRA? [If the
material is not a solid waste, or is excluded, RCRA
requirements are not applicable and, in almost all cases,
will not be relevant and appropriate.]
(2)	(a) Is the solid waste also a RCRA hazardous waste? (b)
If so, is the hazardous waste excluded from Subtitle C
regulation? [Non-hazardous or excluded hazardous wastes
are regulated under Subtitle D and therefore Subtitle C
requirements are not applicable; however, Subtitle C
requirements should be considered if they are relevant and
appropriate.]
[Note: Environmental media such as ground water and
soil are not solid wastes; however, RCRA hazardous
waste regulations may still apply if these media contain
RCRA hazardous wastes. These "contained-in" wastes
will be discussed in a forthcoming fact sheet.]
(1) IS THE CERCLA MATERIAL A SOLID WASTE?
A solid waste, which may be in solid, semi-solid, liquid, or
contained gaseous form, is defined by 40 CFR 261.2 as a
material that is discarded; that is, it is:
#	abandoned;
#	recycled (in certain ways); or
#	considered inherently waste-like.
Materials are solid wastes based on both their nature and how
they are managed. Materials are solid wastes if they are
abandoned bv being (1) disposed of, (2) burned or incinerated,
or (3) accumulated, stored, or treated before or in place of
being abandoned. Determining if a material is a solid waste
becomes more complicated when the material is to be
recycled rather than disposed. Highlight 1 explains when
recycled materials are considered solid wastes, as well as
when materials destined for recycling are excluded from
regulation as solid wastes. Determining the regulatory status of
recycled materials is an issue primarily for active
facilities; nearly all wastes found at Superfund remedial sites
generally will be considered solid wastes if they have been
present at that site for some time. This is because

Highlight 1: REGULATION OF RECYCLING PROCESSES AND RECYCLED MATERIALS
Only certain materials that are recycled in certain ways are excluded from regulation as solid wastes under RCRA. There are for basic ways materials can be
recycled and not be considered solid wastes. Three of the four ways are found in 40 CFR 261.2(e)(1). Note that 40 CFR 261.2(e)(2) sets limiting conditions
on the recycling activity that may limit whether someone can claim the material is not a solid waste. The fourth way is in 40 CFR 261.4(a)(8), which includes
limiting conditions directly in the text of the regulation.
In addition to these four basic ways, there are certain materials that, when recycled in certain ways, are not solid wastes. These materials and recycling activities
are spelled out in 40 CFR 261.1(c). The table below summarizes these materials and the recycling activities. The table shows when materials are solid wastes,
based on recycling activity. As shown in the table, only certain materials that are reclaimed or, in one case, accumulated speculatively are not solid wastes.

most materials that have not been recycled within a certain
timeframe are classified as "solid wastes."
Certain materials are excluded from the definition of a solid
waste regardless of how they are managed and the
concentrations of toxic constituents they contain. By definition,
these materials also can never be hazardous wastes. Materials
excluded from the definition of a solid waste are listed in
Highlight 2.
(2) IS THE SOLID WASTE A HAZARDOUS WASTE?
To be a RCRA hazardous waste, a CERCLA material
must first be a solid waste. Once site managers have
determined that they have a solid waste, they must next
determine if that waste is hazardous based on one of the
following conditions:
(1)	The material is a listed waste;
(2)	It exhibits a hazardous waste characteristic:
(3)	It is a mixture of a solid waste and a listed hazardous
waste; or
4) It is derived from the treatment, storage, or disposal of a
listed hazardous waste.
(5) In addition, if a listed hazardous waste is contained in a
non-solid-waste matrix, it may require management
Highlight 2: RCRA SOLID WASTE EXCLUSIONS
Certain categories of materials are not regulated as solid wastes under
40 CFR 261.4 (and, therefore, can never be hazardous wastes):
#	Domestic sewage;
#	Industrial wastewater discharges regulated under §402 of the
Clean Water Act (i.e., those discharged under an NPDES permit);
#	Irrigation return flows;
#	Source, special nuclear, or byproduct material as defined by the
Atomic Energy Act of 1954 (this does not exclude regulation of
all radioactive material);
#	Materials subjected to in-situ mining techniques that are not
removed from the ground as part of the extraction process;
#	Pulping liquors that are reclaimed in a pulping liquor furnace and
then reused in the pulping process; and
#	Spent sulfuric acid used to produce virgin sulfuric acid.
as a hazardous waste as long as the matrix contains the
hazardous waste.
A waste may be both a listed waste and a characteristic
waste, and all applicable waste codes must be identified.
Mixtures of solid wastes and listed hazardous wastes, wastes
derived from listed hazardous wastes, and listed hazardous
wastes contained in non-solid-waste matrices will be
discussed in later fact sheets.

Highlight 3: RCRA HAZARDOUS WASTE EXCLUSIONS
The following categories of solid wastes are excluded from Subtitle C
standards and are never regulated as RCRA hazardous wastes (but
remain subject to Subtitle D standards):
#	Wastes delisted under 40 CFR 260.20 or 260.22; and
#	Wastes given categorical exclusions, including:
—	Household wastes;
—	Trivalent-chromium wastes (e.g., wastes from the leather
tanning industry);
—	Arsenical treated wood products; and
—	Specified large-volume/low toxicity wastes for which Subtitle
C regulation is not appropriate (e.g., coal combustion wastes,
oil and gas production wastes, and certain mining/mineral
processing wastes).
Some categories of hazardous wastes are wholly
excluded from Subtitle C regardless of their properties (see
Highlight 3). In addition, if wastes are managed in certain
ways, such as those shown in Highlight 4, they are exempt
from RCRA hazardous waste regulation. Other wastes, such
as used oil, may or may not be RCRA hazardous wastes,
depending on their properties and how they are managed.
Highlight 5 discusses when used oil is regulated as a solid
and hazardous waste. The different categories of hazardous
wastes are discussed below.
Listed Hazardous Wastes
Any waste listed in Subpart D of 40 CFR Part 261 is a
RCRA listed hazardous waste, including:
#	Wastes from non-specific sources in Part 261.31 and
identified by F waste codes:
#	Wastes from specific sources listed in Part 261.32 and
identified by K waste codes.
#	Acutely hazardous commercial chemical products listed in
Part 261.33(c) and identified by P waste codes: and
#	Toxic commercial chemical products listed in Part
261.33(f) and identified by U waste codes.
For a CERCLA response involving treatment, storage, or
disposal, specific knowledge of the generation process of the
waste is generally required for the waste to be considered a
listed waste and for the corresponding RCRA requirements to
be applicable. If this information is not available, RCRA
requirements still may be relevant and appropriate (see
Superfund Guide #7, Determining When Land Disposal
Restrictions (LDRs) Are Relevant and Appropriate to
CERCLA Response Actions. December 1989, Superfund
Publication 9347.3-08FS). Listed hazardous wastes commonly
found at Superfund sites include the following:
Highlight 4: EXEMPTIONS UNDER RCRA FOR SOLID AND
HAZARDOUS WASTES
Certain solid and hazardous wastes are exempt from regulation
under RCRA, including the following:
#	Wastewaters, including treated ground or surface water, that are
discharged to surface water under a NPDES permit or through a
sewer system to a publicly owned treatment works (POTW)
(40 CFR 261.4(a)( 1 )(ii)).
#	Wastewaters, including treated ground water or surface water,
that are discharged to surface water under the substantive
requirements of a National Pollutant Discharge Elimination
System (NPDES) permit (40 CFR 261.4(a)(2)).
#	Wastewaters that are treated in exempt wastewater treatment
units under 40 CFR 264.1(g)(6) or 265.1(c)(10) (although any
sludges that are hazardous are subject to Subtitle C).
#	In addition, treated contaminated ground water that is
reinjected into an aquifer during a CERCLA response action or
RCRA corrective action is not subject to the RCRA land
disposal restrictions (LDRs). (This waste is subject to RCRA
§3020, which specifies three conditions that must be met for
reinjection of treated contaminated ground water: (1) the
injection is a CERCLA response action or RCRA corrective
action; (2) the contaminated ground water is treated to
substantially reduce hazardous constituents prior to such
injection; and (3) the action is sufficient to protect human
health and the environment upon completion.)
F001-F005 Spent Solvent Wastes
The listings identify several of the most common spent
industrial solvents as hazardous such as spent methanol,
toluene, acetone, trichloroethylene, and methylene chloride.
However, many materials that contain these constituents are
not considered RCRA listed hazardous wastes because of the
manner in which the spent solvents are defined. Site managers
are not required to presume that a CERCLA hazardous
substance is a RCRA hazardous waste unless there is
affirmative evidence to support such a finding. Therefore, site
managers generally must know specific information to
determine that CERCLA wastes are F001-F005 listed wastes,
including whether:
#	The wastes are spent (used) and cannot be reused without
reclamation, regeneration, or other reprocessing;
#	The wastes were used specifically for their solvent
properties (i.e., for their ability to dissolve or mobilize).
Solvents are not covered by the listing if they were used as
reagents or as ingredients in a formulation. If the wastes
were used as both solvents and reagents or ingredients
(e.g., paint), they are not regulated as RCRA listed wastes;

Highlight 5: REGULATORY STATUS OF USED OIL
Used oil is defined inRCRA §1004 as any oil that has been (1)
refined from crude oil; (2) used; and (3) as a result of such use,
contaminated by physical or chemical impurities. Used oil may be
regulated in various ways, including:
#	Used oil that is disposed of or incinerated without recovery of
energy and that exhibits a characteristic (including the toxicity
characteristic) of a hazardous waste or is mixed with a listed
RCRA hazardous waste is considered a RCRA hazardous
waste. This waste is subject to all RCRA hazardous waste
standards. Used oil that contains greater than 1000 ppm total
halogens is presumed to have been mixed with a listed
hazardous waste.
#	Used oil that exhibits one or more of the characteristics of
hazardous waste but is recycled in some manner other than
being burned for energy recovery is exempt from Subtitle C,
but is still regulated as a solid waste.
#	Used oil that is burned for energy recovery is regulated under
40 CFR Part 266 Subpart E as either on-specification or off-
specification used oil fuel. Used oil that is mixed with listed
hazardous waste or produced from hazardous waste by
processing, blending, or other treatment and is burned for
energy recovery is specifically regulated under 40 CFR Part
266 Subpart D as hazardous waste fuel.
#	Used oil that is hazardous by characteristic is prohibited from
being used as a dust suppressant, unless it is hazardous solely
for exhibiting the ignitability characteristic.
# The wastes are spent solvent mixtures or blends. Site
managers must know that the mixtures or blends contained
-- before use ~ a total of 10 percent or more (by volume)
of one or more of the solvents listed in F001-F005.
(Because the 10 percent cutoff applies to the solvent prior
to use, the concentration of the solvent in the wastestream
is not a factor in determining whether it meets an
F001-F005 listing.) Site managers should note that wastes
determined not to be spent solvent wastes may still be
hazardous by exhibiting a characteristic (e.g., toxicity).
F006-F009 Electroplating Wastes
Electroplating wastes, listed as waste codes F006-F009,
generally contain cyanides and various metals, such as
cadmium, chromium, lead, nickel, and silver. RCRA hazardous
waste listings for these wastes are usually very
chemical-specific (e.g., F009 is listed as "spent stripping and
cleaning bath solutions from electroplating operations where
cyanides are used in the process"). (See 51 FR 43351.) Site
managers generally must apply all of the information contained
in the listing to the wastes in order to determine that the wastes
are F006-F009 listed hazardous wastes.
F020-F023 and F026-F028 Dioxin-Containing Wastes
The dioxin-containing wastes, F020-F023 and F026-F028,
include RCRA hazardous constituents that are generated from
specific operations, such as chlorinated dibenzo-p-dioxins
(CDDs), chlorinated dibenzofurans (CDFs), and chlorophenols.
For example, F027 is defined as discarded unused formulations
containing tri-, tetra-, or pentachlorophenol or discarded unused
formulation containing compounds derived from these
chlorophenols. Site managers must apply all the information in
the listing of a particular dioxin-containing waste to determine
if it is an F020-F023 or F026-F028 RCRA listed hazardous
waste.
K001 and F032. F034. and F035 Wood Preserving Wastes
Wood preserving wastes may include constituents such as
naphthalene, pentachlorophenol, toluene, dioxins, and lead. One
listing, K001, is very specific (i.e., "bottom sediment sludge[s]
from the treatment of wastewaters from wood preserving
processes that use creosote and/or pentachlorophenol"), and
site managers generally must apply all of the information
contained in the listing to the wastes to determine that the
wastes meet the listing. EPA recently listed the following three
wood preserving wastes as F wastes: F032, F034, and F035,
which include wastewaters, process residuals, preservative
drippage, and spent formulations from wood preserving
processes using chlorophenolic formulations, creosote
formulations, or inorganic preservatives containing arsenic or
chromium This new listing likely will increase the amount of
wastes regulated as RCRA hazardous wastes at wood
preserving sites.
F039 Multi-Source Leachate
EPA has given multi-source leachate, defined as leachate
derived from the treatment, storage, disposal, or recovery of
more than one listed hazardous waste, a new waste code,
F039. (Leachate derived from the exclusive management of
more than one of the listed dioxin-containing hazardous wastes
(i.e., F020-F023 and F026-F028) is classified as a single-source
dioxin waste and is not considered multi-source leachate.)
Under the land disposal restrictions (LDRs), the Agency has
established one set of wastewater treatment standards and one
set of nonwastewater treatment standards for this code. These
standards set concentration levels for the entire Best
Demonstrated Available Technology (BDAT) list of
constituents (approximately 200 in total) that may be found in
multi-source leachate.
If a waste is F039, site managers must manage the waste
for all of the BDAT constituents found. If wastes are
determined to be F039 multi-source leachate, site managers
must ensure that the appropriate LDR treatment levels for all
constituents are achieved before disposing of the wastes.

-------
Residuals from the treatment of the wastes would also be
considered F039 under the existing derived-from rule and
would have to be managed in accordance with Subtitle C
regulations.
Other F and K Wastes
Other F-waste codes include metal heat-treating, aluminum
coating, and chlorinated aliphatic hydrocarbon production
wastes. Other wastes having a K code can include petroleum
refining, steel production, organic chemical, and veterinary
pharmaceutical production wastes. Because of the specificity
of these listings, as shown above with the K001 wood
preserving wastes, site managers may be required to know the
following to determine if the waste is a RCRA hazardous
waste:
#	Specific manufacturing process used in generating the
wastes;
#	Feedstocks or catalysts used in a process (the change of
a catalyst in a manufacturing process that formerly
generated a RCRA hazardous waste may result in a waste
not considered a RCRA listed hazardous waste); and/or
#	Specific process unit from which the wastes came.
If such information is not available, and it cannot be determined
positively that a waste is a listed waste, RCRA requirements
may still be relevant and appropriate.
P and U Wastes
The commercial chemical product listings, P and U wastes,
are limited in their applicability and cover only unused and
unmixed commercial chemical products, particularly
off-specification (off-spec) products that are disposed of or
abandoned. (Used or mixed commercial chemical products are
not considered hazardous wastes under RCRA unless they are
listed elsewhere in the regulations under the F- or K-waste
listings or they exhibit a characteristic.) To determine that
CERCLA wastes are P or U wastes, site managers generally
must have evidence that the wastes were products that were
not used; however, this likely will occur only at facilities that
manufacture the listed substance, that have stored the
substance, or that have a record of using such substances as
product or an ingredient in a process. Site managers should
know whether the wastes:
#	Are discarded (i.e., the wastes are abandoned, recycled, or
considered inherently waste-like as described in 40 CFR
261.2(a)(2));
#	Are of a grade that is sold commercially, or are off-spec
commercial products;
#	Have not been used. If wastes are found spilled onto
soil, site managers must know that they were not used
before the spill to determine that they are P or U wastes;
and
#	Were the sole active ingredient, if in a formulation (e.g.,
pesticide).
The P and U listings also provide that any residues or
contaminated soil, water, or other debris resulting from the
cleanup of a spill of any of the P and U wastes are themselves
listed hazardous wastes (40 CFR 261.33(d)). Based on this
regulatory provision, the "contained-in" policy (see note on
page 1) would not apply for soil or debris contaminated with P
or U wastes. Site managers would have to know, however, that
the spill resulted clearly from P or U wastes. For example, it is
not sufficient to know that benzene is in the soil; site managers
must know that the benzene was a P or U waste before being
spilled onto the soil.
If commercial chemical products in the P or U lists were
mixed together as a multi-ingredient formula, the resulting
mixture is not a P or U waste. Similarly, if the same mixture is
dumped onto soil, the soil is not considered to contain listed
wastes. However, if P and U wastes are dumped onto soil or
discarded in a pit, the resulting contaminated soil is considered
to be P or U hazardous wastes.
Characteristic Hazardous Wastes
According to 40 CFR Part 261, if a solid waste exhibits one
of four characteristics, it is also a hazardous waste unless
exempt from regulation under 40 CFR 261.4(b). The four
characteristics of hazardous wastes are:
#	Ignitabilitv. A liquid material is ignitable if it has a flash
point lower than 140°F as determined by a
Pensky-Martens Closed Cup Tester (using the test method
specified in ASTM Standard D-93-79 or D-93-80) or a
Setaflash Closed Cup Tester (using the test method
specified in ASTM Standard D-3278-78). Solid and
gaseous materials may also be ignitable, but different
standards apply to such materials. Solid materials are
ignitable when they are capable of causing fire through
friction, absorption of moisture, or spontaneous chemical
changes, and, when ignited, of causing a hazard from
vigorous burning. An ignitable gas is determined to be
hazardous according to the standards of 49 CFR 173.300.
#	Corrosivitv. A liquid material is corrosive if (1) it has a pH
less than 2; (2) it has a pH greater than 12.5; or (3) it is
capable of corroding steel at a rate of more than a quarter
of an inch per year, based on the test method specified in
NACE Standard TM-01-69. Solid and gaseous materials
are never considered corrosive.
#	Reactivity. A material is reactive if (1) it is explosive; (2)
it reacts violently with water; or (3) it generates toxic
gases when exposed to water or other liquids that
Word-searchable version - Not a true copy

-------
are moderately acidic or alkaline. There are not specific
test methods that determine if a waste is reactive; as a rule
of thumb, wastes that contain total cyanides below 250
mg/kg and total sulfides below 500 mg/kg are generally not
reactive. Above these levels, the wastes may potentially be
characteristically reactive.
# Toxicity. A waste exhibits the toxicity characteristic if,
according to the toxicity characteristic leaching procedure
(TCLP) test, the extract of the waste exceeds the
regulatory concentration level of any of 39 specified
constituents.
The toxicity characteristic rule (55 FR 11798, March 29,
1990) requires use of the TCLP test in place of the extraction
procedure (EP) test to determine whether wastes exhibit the
characteristic of toxicity. The TC rule established regulatory
levels for 25 organic chemicals that were not previously
regulated (DO 18-D043) and retains the regulatory levels (based
on the TCLP) for the 14 waste codes originally regulated under
the EP (see Highlight 6 for details on the TC levels). Because
the new chemicals regulated are organic constituents
commonly found at Superfund sites, it is likely that more wastes
will exhibit the TC under the new rule than were hazardous
under only the EP test. As with the EP, site managers are not
required to test their wastes to determine if they exhibit the TC;
knowledge of the wastes may be sufficient to make this
determination. If specific knowledge of CERCLA wastes is not
available at a site, however, testing will most likely be
necessary. The 25 new organic constituents are designated as
"newly identified" wastes and currently do not have treatment
standards under the LDRs. However, these wastes must be
disposed of in accordance with other Subtitle C requirements
(e.g., in a regulated Subtitle C disposal unit). For more
information on constituents that are regulated by the TC rule
and compliance with the rule, see CERCLA Compliance with
the RCRA Toxicity Characteristics Rule: Part II. October
1990, Superfund Publication 9347.3-11FS.
Mineral Processing Wastes
The 1980 mining waste exclusion (RCRA
§3001(b)(3)(A)(ii)) excluded all solid wastes generated in the
extraction, beneficiation, and processing of ores and minerals
from regulation as hazardous wastes under Subtitle C.
Recently, all mineral processing wastes were removed from
the mining waste exclusion and are now regulated as hazardous
wastes, except for twenty mineral processing wastes, which
have been retained under the mining waste exclusion; see
Superfund Guide to RCRA Management Requirements for
Mineral Processing Wastes. 2nd Edition. Publication
9347.3-12FS).
Mineral processing wastes would have to exhibit the
toxicity characteristic or one of the other three characteristics,
or be listed as a RCRA hazardous waste to be regulated under
Subtitle C. As with other CERCLA wastes, testing is only
necessary if the site manager does not have sufficient
knowledge of the waste. All mineral processing wastes that are
considered RCRA hazardous wastes are designated as "newly
identified" wastes and will not have treatment standards under
the LDRs until EPA completes a separate rulemaking.
However, these formerly excluded wastes that are now
considered hazardous must be disposed of in accordance with
other Subtitle C requirements (e.g., in a regulated Subtitle C
disposal unit) unless they are delisted or treated to remove the
characteristic(s) that makes them hazardous. Wastes that are
still excluded from Subtitle C regulation, such as extraction or
beneficiation wastes, or that do not exhibit a characteristic and
are not listed, must be managed in accordance with Subtitle D
of RCRA.
