AGENCY: Environmental Protection
Agency.
ACTION: Interim final rule with request
for comments.

SUMMARY: On March 29,1990, the
Environmental Protection Agency (EPA)
promulgated revisions to the toxicity
characteristic, one of several
characteristics used to identify waste
regulated as hazardous under Subtitle C
of the Resource Conservation and
Recovery Act (RCRA). Since the
promulgation of the Toxicity
Characteristic (TC), the Agency has
received information that the rule's
immediate application may cause
certain used chlorofluorocarbon (CFG)
refrigerants to be subject to hazardous
waste regulations because they exhibit
the TC. EPA is concerned that
subjecting used CFG refrigerants to
Subtitle C regulations will promote
continued or increased venting,
increasing the levels of ozone-depleting
substances in the stratosphere. As a
result of this new information and to
allow time for gathering additional
information and giving all relevant facts
careful consideration, the Agency is
promulgating today's interim final rule
to suspend the TC rule for used
refrigerants which exhibit the toxicity
characteristic and which are recycled.
The exemption only applies if the
refrigerants are reclaimed for reuse. At
the same time, the Agency if) seeking
public comment on the merits of this
suspension.
DATES: Effective Date: February 5,1991.
 Comment Date: Comments must be
 submitted on or before April 1,1991.

L Background

A Refrigeration System Operations

   Vapor compression refrigeration .  •
 systems typically use CFG refrfgeranta
 as the working fluid. The most common
 refrigerants include CFC-11,12; 114, 502
 and HCFC-22. These cycles are dosed
 systems, relying on the ability to
 continually compress and evaporate the'
 refrigerants to provide the proper heat
 transfer for cooling.
   CFC-11  is typically a liquid at room
 temperature, but because its boiling
 point is around 75 °F, it volatilizes
 easily. An infrequently used refrigerant,
 CFC-113, also has a high boiling point
 (117 °F). However, the other more
 common refrigerants, such as CFC-12
 and HCFC-22, have very low boiling
 points (—21 and —41 degrees F
 respectively), which cause them to
 immediately .volatilize; therefore*  they
 are not likely to leach from wastes into
 groundwater in any measurable
 quantities.
   Refrigerants, as the working fluid of a
 mechanical cooling process, are not
 deliberately vented or removed from the
 system,1 unless the systems are being
 tested, serviced, maintained, retired, or
 retrofitted to use new CFG alternatives.
 In order to service the refrigeration
 hardware, the closed refrigeration loop
 must be opened. Because of the rapid
 volatilization of CFG refrigerants when
 they are released from the closed
 refrigerant system, traditional service
 and maintenance procedures involved
 venting, the refrigerant However,
 because of environmental concern
 regarding ozone depletion, recent
 international regulations phasing out
 production of CFCs, (see London
 Amendments to the Montreal Protocol)
 and increased price and decreased CFC
 availability, service technicians are
 beginning to capture and reuse
 refrigerant

 B. RCRA Applicability

   RCRA regulations apply to materials
 that are solid wastes (including solids,
 liquids, semi-solids, and contained
 gases), as that term is denned in 40 CFR
 261.2. Used Refrigerants are considered
 spent materials, and if reclaimed, are
 solid wastes under 40 CFR 261.2(c)(3).
 However, a limited subset of used
 refrigerant i-e., those which are used or
 reused without prior reclamation, are
 .not subject to regulation under the
 RCRA hazardous waste program (see 40
 CFR 261.2(e)(l)(ii)).
   On March 29,1990 (55 FR11798), EPA
 promulgated the Toxicity Characteristic
 to replace the EP toxicity characteristic.
, (The TC went into effect September 25,
 1990.) The Toxicity Characteristic is
 used to identify solid wastes which are
 identified as.hazardous based on the
 presence of constituents that may leach
 from the waste. The TC expanded the
 range of wastes subject to subtitle C
,  {hazardous waste) controls, because a
 number of constituents not regulated
 under the EP toxicity characteristic,
  •which it replaced, were included in the
 TC,
    Two of the new TC constituents may
  be present in certain used refrigerants
  (e.g., those containing CFC-11) and are
  likely to leach from the waste at levels
  that may cause the used refrigerants to
  be subject to the federal hazardous
  waste regulations. The two constituents
  which are of concern in CFC-11 are
  carbon tetrachloride, which is present hi
  used CFC-11 refrigerant at levels of 25-
  115 mg/1, and chloroform, present hi
  uted;CFC-ll refrigerant at levels of 6-52
  mg/1. (The TC regulatory level for

Federal Register / Vol. 56,
                                            / Wednesday,, February 13. .1991 /  Rules and Regulations  JSMJL
carbon tetrachloride is 0.5 mg/I, and for
chloroform, it is 6.0 mg/1.) These
contaminants are present in !ow levels
in tide manufacturing raw feedstock
required to produce CFG-11 and are left
over in used CFC-11 and remain aa
residuals in used CFC-U. Thus when
the refrigerant is removed from the
refrigeration system, it may contain  -
carbon tetraehloride and/or chloroform
at levels that cause it to exhibit fee
characteristic of toxicity. See the data
provided in the August 29,1998 letter
from C.A. McCain of EJ.EtaPantde
Nemours and Co., to Ms. Lena Nirk of
EPA, available for public viewing in the
docket for this notice.
  For the data oa CFC-11 provided in
the docket, there is no documentation of
the analytical methods or quality
control/quality assurance procedures
used. We also do not have  data on other
CFCrefrigerants, e^, CFC-113. EPA
solicits comments on whether other data
are available that can, be used to
determine whether used CFC
refrigerants are TC hazardous. EPA also
solicits comment on whether the
suspension should be extended to
hydrofluorocarbon (HFC) refrigerants,
which are being used as refrigerants (for
example, in mobile air conditioning
systems); EPA has no data at all on
whether MFCs would exhibit any
hazardous waste characteristics when
removed from refrigeration systems.
C. Previous EPA Actions on
Refrigerants
   The issue of RCRA applicability to
refrigerants being recycled ha* been
discussed previously; see the July 28,
1989 Federal Register notice (54 FR
31335) describing die status of recycled
refrigerants under the 1889 Federal
hazardous waste regulations. Under the
regulations in place from 1980 to 1990,
recycled refrigerants were unlikely to be
Federally regulated as hazardous
 wastes because they would not have
 exhibited any of the characteristics of
 hazardous waste, nor did they fit any of
 the hazardous waste Mating descriptions.
 However, as discussed above, the TC
 regulation promulgated on March 29,
 1990, which added new constituents to
 the Toxicity Characteristic, may change
 the RCRA regulatory status of those
 recycled refrigerants containing carbon
 tetrachloride or other Toxicity
 Characteristic constituents.
   No commenters OH the original
 Toxicity Characteristic proposal raised
 the issue of possible negative impacts
 on recycling of used refrigerants if they
 were to become regulated as hazardous
 wastes. One reason this may have
 occurred is that at the time of the
 original TC proposal (June 13,1988; see
                              51 FR 21648) most refrigerants were
                              being vented and recycling was not
                              feasible.
                                EPA has taken a related action under
                              the Clean Ah- Act by issuing an
                              Advanced Notice of Proposed
                              Rulemaking fANPRM) on May 1,1990
                              (55 FR 18258} to develop a national CFC
                              and baton recycling program. Some
                              commenters on that notice raised
                              concerns about RCRA applicability to
                              recycled refrigerants and described
                              potential disruption of recycling markets
                              if refrigerant is managed as a hazardous
                              waste under RCRA. However, the
                              commentere did not specifically mention
                              the Toxicity Characteristic.
                              D. Regulations under the Clean Air Act  •
                                The recently enacted amendments to
                              the Clean Afar Act require EPA, by 1992.
                              to issue regulations regarding the use
                              and disposal of certain CFCs m
                              appliances and industrial process
                              refrigeration units. The regnlations must
                              include requirements to maximize
                              recapture and,recycling and ensure safe
                              disposal. The amendments, as a general
                              rule,  also prohibit venting of certain
                              CFCs to the environment.
                                The new Clean Air Act authority is
                              the Agency's best available tool to limit
                              CFC  emissions. The Clean Air Act
                              authority enables the Agency to regulate
                              the handling, recycling, reuse and
                              disposal of CFCs by refrigerant
                              recydters, service technicians and
                              equipment owners and manufacturers.
                              When EPA proposes and finalizes a
                              prohibitioa on venting
                               chlorofiuosoearbons under the Clean Air
                              Act,  and the prohibition becomes
                               effective, the Agency will reconsider the
                               issue of RCRA applicability to used CFC
                               refrigerants being recycled.

                               II. Application of Existing Regulatory
                               Framework
                               A. Definition of Solid Waste
                                 One  of the first questions that arises
                               in determining RCRA applicability to
                               refrigeration system maintenance and
                               repair is whether a material is a solid
                               waste. The hazardous waste regulations
                               of RCRA Subtitle C apply to materials '
                               that, are "solid wastes," which are
                               defined in RCRA section 1004f27) as
                               * * * discarded material including solid,
                               liquid, semi-solid, or contained gaseons
                               material resulting from industrial,
                               commercial, mining, and agricHltaral
                               operations, and from community activities
                               * * *
                               Contained gases thus clearly are solid
                               wastes under RCRA, whereas
                               uncontained gases not associated with
                                EtoSd waste management units are
                                outside of RCRA.
   As stated in tide July 28,19B9 Federal
 Register (54 FR 31336), EPA's regulations
 classify the used refrigerants as spent
 materials that are solid wastes when
 reclaimed. (The refrigerants must be
 collected as a contained gas under this
 scenario.) See 4O CFR 261.2{c)(3). If the
 waste also exhibits a characteristic of a
 hazardous .waste, it is a hazardous
 waste in addition to being a solid waste.
 Thus, the equipment servtcerwho must
 remove the chlorofluorocarbon
 refrigerants hi order to service the
 equipment must decide whether to vent
 them (and thus avoid hazardous waste
 regulatory requirements) or collect them
 and possibly be required to manage
 them as hazardous wastes. EPA is
 concerned that, if the refrigerants are
 regulated as hazardous wastes, most
 servicers will vent the material rather
 than collect it for recycling.

 B. Refrigerant Handlers' RCRA
 RequiremeBts
   This section presents the hazardous
 waste requirements for handlers of used
 CFC refrigerants being reclaimed, if  .
 those used CFC refrigerants were to be
 classified as hazardous wastes because
 they exhibit the Toxicity Characteristic.
 The requirements described here are
 suspended by today's action (discussed
 further in section IV of this notice).
   Currently, fee owners of refrigeration
 equipment using CFC refrigerant as the
 heat transfer fluid are coasidtered
 hazardous waste generator* if the used
 CFC refrigerant exhibits the
 characteristic of Toxfeity, and if they
 collect the used CFC refrigerant for
 reclamation or disposal. In addifios,
' parties who repair or maintain the
 ^refrigeration equipment under contract
 wife the equipment owners would be
 "co-generators" if then- actions produced
 hazardous waste, or caused it to be  .
 subject to regulation (see 45 FR 72026,
 October 30,1990). Parties co-generating
 hazardous waste must arrange among
 themselves who is to take responsibility
 for managing the hazardous waste,
 although all parties remain potentially
 liable for hazardous waste
 mismanagement
    As of September 25,199O, generators
 who generate more than 1000 kg of
 hazardous waste per month must
  manage their TC hazardous wastes
  according to the requirements in 40 CFR
  parts 261 and 262 and other relevant
  parts of the hazardous waste
  regulations. For generators of 100-1000
  kg of hazardous waste per month, the
  effective date for managing TC
  hazardous wastes according to the
  hazardous waste requirements is March
  29,1991. (Generators; of Jess than 100 kg

-------
                                            30 / Wednesday, Febrdary 13, 1991 / Rules' and Regulations
  hazardous waste per month are
  conditionally exempt from hazardous
  \vaste management standards.)
    In a scenario in which the .
  refrigeration equipment servicer collects
  the CFG refrigerant and transports it
  from a large quantity generator's site for
  recycling, that servicer acts as a
  transporter (in addition to being a co-
  generator) and must comply with the
  requirements in 40 CFR part 263 if the
  used CFG refrigerant exhibits a
  hazardous waste characteristic.
  Transporters may hold hazardous
  wastes at "transfer facilities" for up to
  ten days, consistent with activities
  undertaken in the normal course of
  transportation, without needing a RCRA
  storage permit.
   As of September 25,1990, the
 recycling facility accepting CFC
 refrigerants that are hazardous wastes
 from large quantity generators (greater
 than 1000 kg/month) must meet the
 definition of a "designated facility,"
 which requires that the facility either
 has a permit or interim status, or meets
 certain other conditions as a recycling  •
 facility (see 40 CFR 260.10 for the  '
 definition of designated facility).
 III. Issues Arising From the TC Rule

 A. Impacts on Recycling Markets
   EPAhas^received information since
 promulgation of the TC indicating that
 certain companies currently recycling
 CFC refrigerants may stop doing so if
 they must manage the CFC refrigerants
 as hazardous wastes. See Items No. 2-7
 in the public docket for this notice.
 These companies and other groups
 generally cite the cost and complexity of
 the hazardous waste regulations, along
 with specific RCRA requirements such
 as manifesting, and other requirements
 that may be imposed at the local level
 as a result of the hazardous waste
 requirements (i.e., rezoning refrigerant.
 distribution centers as hazardous waste
 transfer stations), as reasons that
 recycling will diminish or cease.
 Although EPA Is still evaluating the
 merits of the arguments presented by
 the parties submitting this information,
 EPA is concerned that some of the
 results suggested may cause serious
 environmental harm, the nature and
 significance of which EPA did not
 explore during the TC rulemaking. EPA
 is concerned that the increased
 requirements associated with regulating
 refrigerants as hazardous wastes will
 result in increased venting. EPA has not
 considered the feasibility of
 administrative options to reduce the
 impacts on recycling of these materials
under current RCRA regulations.
Therefore, EPA is suspending
 application of the rule in order to have
 time to evaluate these issues.
   In order to evaluate these issues, EPA
 is soliciting public comment on whether
 handling used CFC refrigerants as a
 hazardous waste is causing or will cause
 a decrease in current recycling rates,
 and whether the decrease (if any) is or
 will be occurring for the reasons these
 parties put forward, or for other reasons.
   To assess the potential impacts of the
 hazardous waste regulations on used
 CFC refrigerant recycling, EPA will
 consider information on the universe of
 used CFC refrigerant handlers (numbers
 of facilities reclaiming, number of
 facilities that use the CFC-11 and other
 refrigerants and would be classified as
 generators if the CFC refrigerants were
 hazardous wastes, and how many
 transporters there are currently). Finally,
 EPA is soliciting comment on whether
 the  concerns can be redressed by
 phased compliance rather than
 exemption, and on whether alternative
 approaches (such as streamlined
 permitting, or reduced manifesting
 requirements) could be used to reduce
 any adverse recycling impact of RCRA
 regulations.
   Under RCRA, there is a requirement
 to obtain a permit prior to beginning
 construction of a hew hazardous  waste
 management facility (if the facility did
 not manage hazardous wastes prior to
 the effective date of regulations for
 those hazardous wastes—see 40 CFR
 270.10(fJ). This requirement exists for
 facilities that intend to treat, store, or
 dispose of hazardous wastes from
 generators other than conditionally
 exempt small quantity generators. (In
 the case of used CFC refrigerants, if
 such facilities had begun storing and  .
 reclaiming used CFC refrigerants  prior
 to September 25,1990, and met certain
 other requirements, they would be able
 to obtain "interim status" and would
 have been able to continue storing and
 reclaiming after September 25. However,
 it appears that few parties were aware
 of the TC's potential application to used
 CFC refrigerants.) EPA believes that this
 requirement may act as a deterrent to
 firms contemplating entering the CFC
 reclamation market after the effective
 date of the TC rules. FJPA notes that the
 preceding discussion applies only to the
 facilities actually conducting the
 reclamation or reprocessing of the
 refrigerants, and not to all refrigeration
 equipment owners who have used
refrigerants that can be reclaimed.
  In addition to potential requirements  .
on reclaimed refrigerants, other factors .
may be influencing the reclamation/
reprocessing, firms' decision to enter the,
CFC refrigerant recycling market.
 Because of the ease with which
 equipment servicers can vent, as
 opposed to collect, used CFC
 refrigerants, and the low cost and ready
 availability of refrigerant, recycling has
 not been common in the past.
 (Equipment design, including the ability
 to attach devices to collect the
 refrigerant, may also influence the
 equipment servicer's decision.) In order
 to increase recycling rates, the
 refrigeration industry must contend with
 both the need to change the equipment
 servicers' behavior, and the need to
 change some equipment design.
   .However, the recent (July 1989)
 implementation of Phase I of the
 Montreal Protocol reduces CFC supplies
 by over 20%, resulting in price  increases.
 In addition, a tax on chemicals that
 deplete the ozone layer further increases
 the price and provides incentives to
 collect used CFC for recycling; this tax
 is scheduled to increase yearly.1 The
 current price of CFCs are at the margin
 at which reeycling becomes
 economically feasible. If used
 refrigerant is regulated as a RCRA
 hazardous waste, the cost of recycling is
 likely to increase enough to make
 recycling economically less attractive.
 Since venting is not currently prohibited,
 venting is likely to continue to  occur
 until the economics of recycling
 improve, or regulations prohibiting the
. venting go into effect.

 B. Impacts on an Orderly CFCPhaseout
 and Transition to CFC Substitutes

   The Agency is concerned that if
 recycling is not practiced due to the
 increased costs of recycling that results
 from handling the used CFC refrigerants
 as RCRA hazardous wastes, industry
 may begin using other, more
 environmentally costly practices. These
 practices could include premature
 retirement of CFC-using equipment or
 retrofitting that equipment to work with
 alternatives. A premature retrofit to an
 alternative that has not yet been
 completely evaluated may result in the
 wrong refrigerant choice, leading to
 negative environmental impacts. The
Agency is currently evaluating  the
 toxicity, global wanning potential,
energy efficiency, safety, flammability,
ozone depletion and materials
compatibility of various alternative
refrigerants. Many of the results will not
be available until 1991-1994, and thus,
information is not currently available to
completely identify alternatives which
  1 EPA analysis indicates that the cost of recycling
is approximately $2 per weighted kilogram of CFC
(see the Advance Notice of Proposed Rulemaking
dated May 1,1990.55 PR 18259).

 satisfy all environmental, health, and
 safety concerns. For instance, a
 premature selection, of an alternative
 that is less energy efficient would result
 in increases in carbon dioxide and other
 air pollutants which may cause
 increases in global warming.
   Recycling CFCs provides the
 opportunity for industry to postpone or
 even avoid entirely the need to retire
 prematurely or retrofit equipment The
 Agency estimates that a recycling
 program in the major air conditioning
 and refrigeration sectors, fufiy
 implemented by the early 1990*8, could
 result in a net saving of over 159,008
 metric tons of CFCs by the year 2000.
 Complymg with RCRA regulations may
 increase venting of GFC refrigerants,
 and thus increase the cost of the
 Agency's CFC phaseout regulations. The
 Agency discussed the potential for
 increasing me costs of a recycling
 program if there are delays in its
 implementation- in an advance notice of
 proposed rulemaking published on May
 1,1990(55 PR 18256).

 C. Environmental Concerns
   In the ANPRM of May 1,1990 fSS PR
 18256), the Agency described the human
 health and environmental risks of CFCs.
 An EPA analysis shows that chlorine
 levels wiB continue to increase from
 current levels of 3.0 to about 4.0 parts
 per billioa fppbj despite a pfeaseoatfe
 production erf controlled substances by
 the year 2000. The Antarctic ozone hole
 was discovered at chlorine levels of
 approximately 2.5 ppb; natural chlorine
• levels are ;7 ppb. Earlier reductions in
 CFCs before 200& would reduce the
 environmental risks fdescribed below)
 even as chlorine levels continue to
 increase over the next decade.
   The largest environmental impact
 from emissions of CFCs comes from the
 chlorine's ability to deplete the ozone
 layer, and thereby increasing the
 amount of ultraviolet radiation reaching
 the earth's surface. EPA believes that an
 increase in UV radiation wiH result in
 increased deaths from skin cancer,
 increased incidence of cataracts,
 reduction in the function of the body's
 immune system, and damage to crops.
 CFG* are also suspected greenhouse
 gases.
   Recycling provides, an opportunity to
 delay or reduce the increase in chlorine
 levels. Indeed, estimates based on  .
 preliminary EPA analysis of a proposed
 recycling program indicate that OB*-
 third of all CFCs could be recycled by
 the turn of the ceatvujy, RecyeJing may
 reduce the peak rate of chlorine- loading
 to the stratosphere, '  '      •
   The Agency is ratrently investigating
 the impact that recycled CFCs may have
on the ozone layer. Since these
chemicals are difficak to destroy it is
likely that they wffl be eventually
released although at a later point in
time,1 EPA is investigating the impact of
their eventual release onpeakcMorine
concentrations. Recent scientific
evidence ssggests feat a redaction of the
peak cMotine concentrations may more
than proportionally reduce ozone
depletion.8 It is lately that delayed or
reduced release of CFCs. due to
recycling ewer the next 30 to 4Q years
will lower the peak of chlorine
concentration.
  The Agency is psonnslgating- today'*
interim final rule with the belief feat UBS
action wiB encourage used refr^scant
recycling. EPA is interested in hearing
from commentHrs who have evidence on
the effect of this exemption. EPA is also
interested in evidence of harmful
environmental or health effects other
than those discussed: in this rolemaking,
Because EPA la attempting to balance
the potential environmental harm
refrigerant recycling markets against foe
potential envnonmentai harm caused by
re:
subtitle C regulatory content EPA is
asking for commenterg to provide any
available infarmation to aid in   .
evaluating die human, health and
environmental effects of these actions,

D. Time Considerations
  Of paramount concern to the Agency
is Ruiigating. the potential for signiftcaat
adverse health and environmental
impacts, as discussed above, while
investigating these issae* further. Under
the Clean Air Act amendments, a
prohibition on venting must become
effective by July 1,1992. Thus because of
the potential seriousness of the risks  .
posed by CSC refrigerant venting, EPA
believes that immediate action, to
temporarily postpone the RCRA
regulation of these materials pending
further investigation is warranted to
mitigate the potential health and
environmental effects. EPA is exercising
its authority under the good cause
exemptions in sections 553{bJ(3J and
553(d)C3J of the Administrative
Procedure Act to immediately suspend!
the requirements imposed as a result of
the TC for CFC refrigerants being
recycled, EPA believer that, wiftoMt the.  •

 S914   Federal Register / Veil. '56,'No.  30 / Wednesday, February 13, 1991 / Rules and Regulations
 the rule as applied to CFG refrigerants
 against the potential public health
 consequences of applying the rule to
 CFG refrigerants in the interim while
 EPA considers the new information. In
 this case, due to the environmental and
 health consequences from ozone
 depletion, EPA believes that the public
 interest may be better served by
 suspending the rule to evaluate the
 consequences. EPA solicits public
 comment on its decision to suspend the
 TO regulation for used CFC refrigerants
 being reclaimed.
 V. State Authorization
 A. Applicability of Rules in Authorized
 States
  Under section 3006 of RCRA, EPA
 may authorize qualified States to
 aciminister and enforce the RCRA
 program within the State. Following
 authorization, EPA retains enforcement
 authority under sections 3008,3013, and
 7003 of RCRA, although authorized
 States have primary enforcement
 responsibility. The standards and
 requirements for authorization are found
 in 40 CFR part 271.
  Prior to the Hazardous and Solid
 Waste Amendments of 1984 (HSWA), a
 State with final authorization
 administered its hazardous waste
 program in lieu of EPA administering the
 Federal program in that State. The
 Federal requirements no longer applied
 in the authorized State, and EPA could
 not issue permits for any facilities that
 the State was authorized to permit.
 When new, more stringent Federal
 requirements were promulgated or
 enacted, the State was obliged to enact
 equivalent authority within specified
 time frames. New Federal requirements1.
 did not take effect in an authorized
 State until the State adopted the
 requirements as State law. In contrast,
 under RCRA section 3006(g) (42 U.S.C.
 8926{g}), new requirements and
 prohibitions imposed by HSWA take
 effect in authorized States at the same
 time that they take effect in  ,
 nonauth6rized States. EPA is directed to
 carry out these requirements and
 prohibitions in authorized States,
 including the issuance of permits,  until
 the State is granted authorization  to do
 so. While States must still adopt
HSWA-related provisions as State law
 to retain final authorization, H,SWA
 applies in authorized States in the
 interim.
B, Effect on State Authorizations
  EPA considers this rule to be part of
 the TC rule, and thus also a HSWA rule.
As a result, EPA will implement the
provisions of today's rule in authorized
 States until their programs are modified
 to adopt the final toxicity characteristic
 and the modification is approved by
 EPA. Implementation of today's rule
 beyond the date of a State's receiving
 final authorization for the toxicity
 characteristic depends upon actions
 taken by the;State, as discussed below.
 EPA will implement the provisions of
 today's rule in unauthorized States.
   Today's rule suspends the
 requirements imposed in the final
 Toxicity Characteristic regulation (see
 55 FR11798, March 29,1990) for certain
 CFC refrigerants being recycled. The
 Toxicity Characteristic was
 promulgated pursuant to a HSWA  -
 provision and must be adopted by
 States which intend to retain final
 authorization. However, today's rule
 provides for a standard which is
 narrower in scope than would be
 imposed in the final Toxicity
 Characteristic for certain CFC
 refrigerants which may fail the
 characteristic and are recycled. In order
 to promote recycling operations, today's
 rule provides that these wastes would
 not be hazardous wastes under the
 Federal regulations, and States would
 not be required to mandate their
 management as such in order to retain
 their RCRA authorization. However,
 Section 3009 of RCRA provides that
, States may impose requirements that
 are broader in scope or more stringent
 than those imposed under Federal
 regulations. States, whether using RCRA
 authorities (e.g., authorities under State
 law where States have received final
 authorization to implement the toxicity
 characteristic provisions in lieu of their
 implementation by EPA), or other State
 authorities under other statutes, may
 impose hazardous waste requirements
 on such operations, or may require other
 more stringent conditions upon
 management of these wastes.

 VI. Additional Information
                           **
 A. Executive Order 12291—Regulatory
 Impacts
   Under Executive Order 12291, EPA
 must determine whether a regulation is
 "major," and|therefore subject to the
 requirement of a Regulatory Impact
 Analysis. The overall effect of today's
 rule would be to suspend requirements
 imposed by the final Toxicity
 Characteristic rule for certain CFC
 refrigerant recycling operations. There
 are no'sampling or analysis
 requirements in today's rule. The net
 effect of this rule is to extend cost
 savings to certain-segments of the
 potentially regulated community.
 Consequently, no regulatory impact
 analysis is required.
 B. Regulatory Flexibility Act
  Pursuant to the Regulatory Flexibility
 Act, 5 U.S.C. 601-612, whenever an
 agency is required to publish a General
 Notice of Rulemaking for any proposed
 or final rule, it must prepare and make  .
 available for public comment a
 regulatory flexibility analysis that
 describes the impact of the rule on small
.entities (i.e., small businesses, small
 organizations, and small governmental
 jurisdictions). No regulatory flexibility
 analysis  is required, however, if the
 head of the Agency certifies that the rule
 will not have a significant impact on a
 substantial number of small entities.
  The suspension of the Toxicity
 Characteristic requirements for certain
 limited CFC recycling activities in this
 rule is deregulatory in nature and thus
 will only provide beneficial
 opportunities for entities that may be
 affected by the rule. Accordingly, I
 hereby certify that this regulation will
 not have a significant economic impact
 on a substantial number of small
 entities. This regulation, therefore, does
 not require a regulatory flexibility
 analysis.

 C. Paperwork Reduction Act
  There are no reporting, notification, or
 recordkeeping (information) provisions
 in this rule. Such provisions, were they
 included, would be submitted for
 approval to the Office of Management
 and Budget (OMB) under the Paperwork
 Reduction Act, 44 U.S.C. 3501 et seq,
