ACTION; Final rule.	

SUMMARY: On September 10,1992, EPA
exempted used oil inserted into crude
oil pipelines from the part 279 used oil
management standards. EPA is today
clarifying the existing pipeline
exemption and expanding the
exemption to other petroleum refinery
applications. Today's document clarifies
that the exemption from the used oil
management standards did not intend to
exclude used oil mixed with crude oil
or natural gas liquids (hereinafter
referred to as "crude oil") in pre-
pipeline units (e.g., stock tanks,
production separators) prior to being
introduced into the crude oil pipeline.
In addition, today's rule expands the
used oil exemption to include
transportation and/or storage of
mixtures of small amounts of used oil
(i.e., less than 1%) and crude oil that are
destined for insertion into a petroleum
refining facility process at a point prior
to crude distillation or catalytic
cracking.
   Today's rule exempts from the part
279 standards, used oil that is inserted
into the petroleum refining facility
process after distillation or catalytic
cracking operations provided that the
used oil meets the used oil specification
prior to insertion.
   Today's rule also exempts from the
 part 279 standards used oil that
 incidentally enters and is recovered
 from a refinery's hydrocarbon recovery
 system or wastewater treatment system
 (i.e., process sewer, storm sewer, or
 wastewater treatment units), if the
 recovered used oil is subsequently
 inserted into the petroleum refinery
 process.
   In addition, today's rule expands the
 definition of transfer facility to allow
 used oil to be held more than 24 hours
 but less than 35 days prior to specified
 activities.
   Finally, EPA is today amending the
 used oil processor standards to clarify
 that a specific set of on-site
 maintenance, filtering, and separation
 activities were not intended to be
 covered under the used oil processor
 standards. EPA is also correcting errors
in regulations that appeared in the May
3,1993, Federal Register.
EFFECTIVE DATE: April 4,1994.

II. Background

A. Summary of Recent Regulatory
Actions Pertaining to Used Oil

1. Summary of May  20,1992, Federal
Register Notice
   On May 20,1992, EPA published a
final listing determination for used oils
that are destined for disposal (see 57 FR
 21524). The Agency determined that
used oils destined for disposal did not
have to be listed as a hazardous waste
because used oils do not typically and
 frequently meet the  technical criteria for
 listing a waste as hazardous. EPA gave
 considerable attention, in reaching its
 determination, to the current Federal
 regulations that govern the management
 of used oils that are disposed, including
 the requirement for used oil that
 exhibits a characteristic of hazardous
 waste under subtitle C of RCRA.
   The May 20,1992, Federal Register
 notice also included a categorical
 exemption from the definition of
 hazardous waste in § 261.4 for non-
 terne-plated used oil filters that have
 been hot-drained to remove used oil.

-------
              Federal Register /  Vol. 59, No. 43  / Friday, March 4, 1994  / Rules and Regulations      10551
 EPA based this exemption on data
 submitted to the Agency indicating that
 these filters do not typically and
 frequently exhibit the toxicity
 characteristic.

 2. Summary of September 10,1992,
 Federal Register Notice

   On September 10,1992, EPA
 promulgated a final listing decision for
 used oils jthat are recycled and
 simultaneously promulgated
 management standards for used oil,
 codified at 40 CFR part 279 (see 57 FR
 41566). EPA determined that used oil
 destined for recycling did not have to be
 listed as a hazardous waste because the
 used oil did not meet the technical
 criteria for listing a waste as hazardous,
 particularity in light of the new
 management standards and other federal
 requirements which control the risks
 posed by improper management of used
 oil. The standards cover used oil
 generators, transporters, processors, re-
 refiners, off-specification burners and
 marketers! The standards included an
 exemption from the management
 standards for used oil placed directly in
 a crude oil pipeline.

 3. May 3, J1993, and June 17,1993
 Correction Notices

   On May 3,1993, EPA published
 technical amendments and corrections
 to the May 20,1992 and September 10,
 1992, Federal Register Notices (see 58
 FR 26421). On June 17,1993, EPA
 corrected several errors in the May 3,
 1993, notice (see 58 FR 33341).

 B. Summary of the 1985 Comments
 Regarding Used Oil Mixed With Crude
 Oil Destined for Refineries

  On November 29,1985, EPA proposed
 to list all used oil as a hazardous waste
 (50 FR 49248). Commenters responded
 that used oil mixed with crude oil be
 exempt from such regulation because
 the small quantities of used oil mixed
 with crude oil posed no threat to the
 environment when refined with crude
 oil.       I

 C. Summary of 1991 Comments

  On September 23,1991, EPA
 proposed that the two exemptions from
 subtitle C requirements promulgated in
 1985 (see 40 CFR 261.6(a)(3) (v)-(viii))
 for oil-bearing hazardous waste and
 fuels derived from these wastes, also
 apply to used oils. (56 FR 48026, 48042)
EPA proposed exemptions from the
used oil management requirements
 (whether or not EPA ultimately listed
used oil asia hazardous waste) for: (1)
Used oils that are reinserted as
feedstocks [at primary petroleum
 refineries; and (2) fuels derived from
 those used oils.
   Commenters (mainly the primary
 petroleum refining industry) stated that
 if EPA chose to list used oil as
 hazardous waste, the Agency should
 exempt used oil that is reintroduced
 into the refinery process from hazardous
 waste or used oil management standards
 requirements. Commenters further
 stated that if EPA did not adopt this
 exemption, the entire refinery process
 could be subject to hazardous waste
 management requirements, including
 permits. Commenters stated that this
 would be unwarranted because the
 reintroduction of used oil into the
 refining process contributes only
 insignificant concentrations of metals to
 the crude oil or finished petroleum
 product. Other Commenters stated that
 refiners that handle used oil should be
 subject to the same requirements for
 used oil management as are used oil re-
 refiners.
   Commenters from the primary
 petroleum refining industry also stated
 that EPA should not limit the exemption
 to those instances where used oil is
 inserted before fluid catalytic cracking
 or distillation, since other conversion
 and distillation processes in the refinery
 would also remove, alter or immobilize
 impurities in the oil. They asserted that
 limiting the point of insertion could
 foreclose the future development of
 used oil recycling activities. These
 commenters also stated that limiting the
 insertion point could preclude refineries
 from accepting DIY oil. Commenters
 asserted that DIY oil might have to
 undergo certain pre-processing at
 refineries prior to its insertion into the
 refining process. They also asserted that
 under the proposed exemption, this pre-
 processing would not be exempt and
 would be a hazardous waste activity.
 Commenters stated that these activities
 are part of the refining process.
   Commenters from the primary
 petroleum industry further stated that
 EPA should extend the exemption to
 apply to used oil inserted into the
 pipeline at marketing, E&P and pipeline
 facilities for use in the refinery process.
 They asserted that used oil recovered
 from oil and gas exploration and
 production is placed in pipelines and
 trucks and returned to the refinery from
 other petroleum facilities. Commenters
 stated that the recovered oils are useful,
 valuable raw materials that are
 reintroduced into the crude stream for
 their economic value.

 HI. Analysis of New Part 279 Provisions
  On September 10,1992, EPA
promulgated a final listing decision for
used oils that are recycled and
 simultaneously promulgated standards
 in 40 CFR part 279 for the management
 of used oil under RCRA section 3014.
 Under § 279.10(g) of part 279, EPA
 granted an exemption for used oils
 introduced directly into crude oil
 pipelines from part 279 standards at the
 point at which they are introduced. EPA
 did not address the proposed
 exemptions for used oil inserted into the
 petroleum refining facility process
 either prior to or after crude distillation
 or catalytic cracking.
   The American Petroleum Institute
 filed a petition for review of the
 September 10,1992, rule, on December
 8,1992, raising the issue that EPA had
 not addressed the proposed exemptions
 for petroleum refining, production, and
 transportation in the September 10,
 1992, final rule. Today's rule responds
 to comments and addresses outstanding
 issues related to used oil and petroleum
 refining facility processes.

 A. Summary of Comments From
 Interested forties
   Today's rule was distributed in draft
 form for comment to the litigants and
 intervenors concerning the 1992 rule,
 and other concerned members of the
 regulated community, States, and
 environmental groups. The primary
 substantive comments received on the
 draft and EPA's responses to those
 comments are summarized below.
   EPA received several comments from
 the petroleum industry on the
 exempdon from part 279 for storage and
 transportation of mixtures of used oil
 and crude oil that contain less than 1%
 used oil and are destined for insertion
 into petroleum refining process. These
 commenters objected primarily to
 provisions in the draft final rule limiting
 the exemption to mixtures that contain
 less thaji 1% used oil. The commenters
 also objected to limiting the amount of
 used oil that can be directly inserted
 into the petroleum refining process to
 1% of the crude oil process unit
 throughput at any given time. EPA has
 retained the 1% limit in both cases in
 today's final rule for reasons discussed
 in section III.B.2 of this preamble.
  EPA received comments from used oil
 re-refiners (i.e., "secondary" petroleum
 industry—a type of used oil processor)
 regarding the regulatory status of
 petroleum refineries that receive used
 oil from off-site and store the used oil
 on-site before mixing it with crude oil.
The draft rule proposed to regulate
petroleum refining facilities as used oil
transfer facilities in these
circumstances. Commenters stated,
however, that petroleum refiners that
receive used oil from off-site pose the
same potential concerns from receipt of

-------
10552      Federal  Register / Vol. 59, No.  43 / Friday, March 4, 1994 / Rules and Regulations
adulterated used oil and improper
storage of used oil as re-refiners and
should therefore be subject to the
requirements for used oil processor/re-
refiners prior to mixing. EPA agrees and
has revised the draft rule accordingly.
These changes are discussed in greater
detail below.
  EPA also received numerous        •
comments on provisions clarifying what
constitutes a used oil processor.
Provisions contained in the draft
document would have prohibited both
on- and off-site burning of used oil
generated from specified activities that
EPA is today clarifying are not subject
to the used oil processor standards.
Commenters stated that the used oil
generated from these activities would be
suitable for burning in accordance with
the part 279, subpart G standards and
that burning should not be further
restricted. In response to these
comments, EPA has decided to allow
on-site burning of the used oil generated
from these activities but has retained the
prohibition against off-site burning. The
basis for this decision is discussed in
section III.C of today's preamble.
B. Section 279.1—Definition of
Petroleum Refining Facility
  Today's rule establishes a regulatory
definition for "petroleum refining
facility." EPA believes it is necessary to
define this term in order to provide a
clear distinction between what the
Agency considers to be and regulates as
primary petroleum refining facilities
and facilities that EPA considers to be
used oil re-refiners for regulatory
purposes. Under today's rule,
"petroleum refining facility" is defined
as follows:
  "Petroleum refining facility" means an
establishment primarily engaged in
producing gasoline, kerosine, distillate fuel
oils, residual fuel oils, and lubricants,
through fractionation, straight distillation of
crude oil, redistillation of unfinished
petroleum derivatives, cracking or other
processes (i.e., facilities classified as SIC
2911).
  A used oil re-refiner, in contrast, is a
facility that processes used oil to
produce lube base stocks and greases,
industrial fuels, asphalt extenders,
diesel like fuels, and other products.
   EPA is aware that petroleum refiners
and used oil re-refiners employ similar
production processes and produce
similar products. Consequently, the
Agency has avoided defining these
facilities in terms of the process steps
 employed to produce a finished product
 or the type of products produced. As
 defined by today's rule, petroleum
refining facilities and used oil re-
refining facilities differ primarily in the
material that constitutes the primary
initial feed to the process. In order for
a facility to be considered a petroleum
refining facility, the material fed to the
front end of the refining process must be
comprised primarily of crude oil. In
order to be considered a used oil re-
refiner, the material entering the front
end of the process must be comprised
primarily of used oil.
C. Section 279.10(g)—Used Oil
Introduced Into Crude Oil Pipelines or
Petroleum Refining Facilities
1. Section 279.10(g)(l)—Used Oil
Introduced Into Crude Oil Pipelines
  The September 10,1992, final used
oil regulations provided an exemption
at § 279.10(g) from management
standards for used oil that is placed
directly into a crude oil pipeline (see 57
FR 41613). Today's rule replaces
§ 279.10(g) with § 279.10(g)(l) which
clarifies the original intent of the
pipeline exemption. Section 279.10(g) of
the September 10,1992, final rule  ;
provided that "Used oil that is placed
directly into a crude oil, oil or natural
gas pipeline is subject to the
management standards of [part 279]
only prior to the point of introduction
into the pipeline. Once the used oil is
introduced to the pipeline, the material
is exempt from the requirements of [part
279]."
   EPA is concerned that the phrase,
"placed directly into a crude oil or
natural gas pipeline," can be literally
interpreted to apply more narrowly than
the Agency  had intended. EPA
understands that it is standard practice
to first mix small amounts of used oil,
typically less than 1%, with crude oil in
stock tanks, production separators or
other tank units that are connected via
pipeline to the petroleum refining
facility (i.e., pre-pipeline units). It was
not EPA's intent to exclude used oil that
is mixed with crude oil in these pre-
pipeline units from the § 279.10(g)
pipeline exemption. Rather, EPA
intended to include this practice within
the meaning of "direct insertion."
Because used oil is typically inserted
into the petroleum pipeline through
these pre-pipeline units, to exclude
these units  from the pipeline exemption
would effectively  render the exemption
meaningless. Clearly this was not EPA's
 intent. Today's rule revises the language
 of the exemption to clarify that used oil
 may be inserted into the pipeline via
 pre-pipeline units (which contain crude
 oil) exempt from the requirements of
 part 279.  It should be noted here that
 the § 279.10(g)(l)  pipeline exemption
 established by today's rule is limited to
 pipelines that convey crude oil from off-
site locations to the petroleum refining
facility. The exemption does not apply
to pipelines that convey crude oil from
one on-site location within a petroleum
refinery to another. If such on-site
piping contains used oil, it is exempt
only if it qualifies under
§§ 279.10(g)(2)-(5) discussed below.
Also, if processing of the used oil is
performed prior to mixing with crude
oil in these pre-pipeline units, such
processing remains subject to the part
279, subpart F standards for used oil
processors and re-refiners. Used oil that
is generated and stored at the pipeline
is subject to the used oil generator
standards prior to mixing with crude
oil. Used oil that is transported to the
pipeline and immediately mixed with
crude oil or stored for less than 24 hours
prior to such mixing is subject to all
Subpart E transporter standards except
for § 279.45 which applies to transfer
facilities. Used oil that is transported to
and subsequently stored at the pipeline
for more than 24 hours and less than 35
days prior to mixing with crude oil is
subject to all the part 279, subpart E
transporter/transfer facility
requirements.
2. Section 279.10(g)(2)—Storage and
Transportation of Mixtures of Used Oil
and Crude Oil
   Section 279.10(g)(2) of today's rule
expands the used oil management
standard exemption to include: (1)
Mixtures of used oil and crude oil
containing less than 1% used oil that
are being stored at the petroleum
refining facility or in discrete units
remotely located from the pipeline, as
long as the mixture is destined for the
refinery and inserted prior to crude
distillation or catalytic cracking; and (2)
mixtures of used oil and crude oil
containing less than 1% used oil that
are being transported (via truck, rail, or
vessel) to the petroleum refinery or the
pipeline for insertion into the petroleum
refining process prior to crude
 distillation or catalytic cracking. The
 former exemption provided at
 § 279.10(g) did not apply either to
mixtures of used oil and crude oil that
 are stored at the petroleum refinery or
 in remotely located units, or to the
 transportation of mixtures of used oil
 and crude oil. The previous, more
 narrow exemption was based on the
 assumption that used oil was placed
 directly into the pipeline (or into units
 directly connected to the pipeline as
 previously discussed). EPA assumed
 that the mixing of used oil and crude oil
 occurred at the point at which used oil
 was inserted into the pipeline. EPA has
 since learned, however, that mixing
 frequently occurs at exploration and

-------
                              4>  1994  /  Rules and Regulations
                                                                                                            10553
 production sites that are remotely
 located from the pipeline or the
 petroleum refinery.
   For example, used oil generated
 during on,- and off-shore drilling
 activities (e.g. from compressors, trucks
 and otherlheavy equipment) is routinely
 mixed with crude oil in units (e.g.
 production separators, seagoing vessels,
 stock tanks, etc.) located at the
 exploration and production site and
 then transported, as a mixture, to the
 pipeline or petroleum refining facility.
 Depending on the location of the
 drilling activities, the mixture of used
 oil and crude oil may need to be
 transported (by vessel, truck, rail, etc.)
 to a separate  location for introduction
 into the pipeline or the petroleum
 refining facility, hi the case of off-shore
 drilling sites  for example, conveyance of
 the mixture may involve multiple
 modes of transportation (i.e., from the
 off-shore platform to land by vessel or
 pipeline and then to the crude oil
 pipeline by land-based transport).
 Today's exemption covers all modes of
 transportation of mixtures of used oil
 and crude or natural gas liquids, as long
 as the mixture contains less than 1%
 used oil and is destined for insertion
 into a petroleum refining facility
 process at a point prior to crude
 distillation or catalytic cracking. In
 addition, today's exemption covers
 storage of mixtures of used oil and
 crude oil, [provided that the mixture
 contains less than 1% used oil and is
 inserted into  a petroleum refining
 facility process prior to crude
 distillation or catalytic cracking.
  Used oil that is generated at
 exploration and production sites
 continues |to be subject to used oil
 generator standards prior to being mixed
 with crude oil such that it is exempt
 under today's rule. Used oil that is
 generated joff-site and transported to or  .
 stored at an exploration and production
 site is subject to the transporter and
 transfer facility standards, as applicable,
 up until the point at which the used oil
 is mixed with crude oil such that it is
 exempt under § 279.10(g)(2).
  EPA is Exempting mixtures of used oil
 and crude [oil held in discrete units at
 a refinery or at remote locations because
 the Agency understands that the amount
 of used oil contained in these mixtures
 is extremely small relative to the large
 quantities |of crude oil. hi developing
today's rule, EPA held numerous
 discussions with petroleum refinery
industry representatives regarding the
maximumjamount of used oil contained
in mixtures of used oil and crude oil
that are destined for insertion into a
petroleum; refining process prior to
crude distillation or catalytic cracking.
 Industry representatives repeatedly
 informed the Agency that used oil
 constitutes less than 1% of these
 mixtures, hi gathering information for
 today's rule, EPA held conference calls
 with representatives from a number of
 petroleum refining companies (e.g.,
 Mobil Oil Corporation and Phillips
 Petroleum Inc.,). The Agency also
 conducted several site visits, including
 visits to an Amoco refinery in Whiting,
 Indiana and a Mobil Oil Corporation
 refinery in Paulsboro, New Jersey. In
 each case, EPA was informed that used
 oil does not currently, and will not
 comprise greater than 1% of the crude
 oil/used oil mixture because of the sheer
 volumes of crude oil that are
 continuously being produced and
 processed relative to the amount of used
 oil that is generated at production sites
 or refineries. This recent information is
 consistent with comments submitted in
 response to the 1985 Used Oil Proposed
 Rule in which Exxon Company, USA
 stated that the average percentage of
 used oil in refinery feed stock streams
 is less than 0.02% and Texaco, Inc.,
 indicated that used oil would constitute
 no  more than 0.01% of the refinery
 input.
  EPA does not believe it is necessary
 to apply the used oil management
 standards to the less than 1% fraction of
 used oil that is being held temporarily
 in discrete units or transported from
 those units to the pipeline or the
 petroleum refinery for recycling as part
 of a mixture that is composed
 overwhelmingly of crude oil. In essence,
 because of the high ratio of crude oil to
 used oil, EPA considers the mixture to
 be equivalent to  crude oil for regulatory
 purposes. EPA's part 279 standards
 were designed to control those
 particular risks associated with the
 management of used oil (e.g.,
 uncontrolled burning, improper storage
 practices by used oil handlers) pursuant
 to section 3014 of RCRA.
  The reason for EPA's imposition of a
 1% limit on the amount of used oil
 contained hi mixtures of used oil and
 crude oil being stored or transported to
 a crude oil pipeline or petroleum
 refinery prior to insertion into the
 refining process is that, while we have
 determined that the small amounts of
 used oil that are being added to crude
 oil under current practices pose no
 incremental risk over normal crude oil,
 we  have not evaluated whether larger
 amounts of used oil also pose no
 incremental risk. Given the information
provided to EPA by the petroleum
refining industry regarding the inherent
limitations on the amount of used oil
that is or should be contained in
mixtures of used oil and crude oil (i.e.,
 less than 1%), and given that EPA has
 received no information, either recently,
 or in response to previous ralemakings ,
 that provides basis for an alternative
 limit, (he Agency sees no point in
 imposing a higher cap. Imposition of a
 higher cap could have the effect of
 encouraging mixing of used oil with
 crude oil that would not otherwise
 occur during the normal course of
 petroleum refining operations. Such an
 incentive might lead to increased
 incremental risk from management of
 large amounts of used oil, exempt from
 the pail 279 standards, at petroleum
 refineries. EPA also concluded that a
 less precise  limit (i.e., "de minimis" or
 "small amounts"), as was suggested by
 some commenters from the petroleum
 refining industry, would needlessly
 cause uncertainty, given that EPA was
 told repeatedly that amounts currently
 introduced are far less than 1%.

 3. Section 279.10(g)(3)—Used Oil
 Inserted Into the Petroleum Refining
 Process Without Prior Mixing and
 Mixtures of Greater Than One Percent
 Used Oil
   As previously stated, under today's
 rule, mixtures of used oil and crude oil
 containing less than 1% used oil that
 are transported to or stored at a
 petroleium refinery, and are introduced
 prior to crude distillation or catalytic
 cracking, are exempt from part 279
 standards under § 279.10(g)(2). It is
 EPA's 'understanding, based on
 information received from petroleum
 industry representatives, that used oil
 can potentially be inserted directly into
 the petroleum refining process prior to
 crude distillation or catalytic cracking
 without either: (1) Mixing the used oil
 with cmde oil feedstocks, or (2) pre-
 processing of the used oil to ensure that
 any contaminants in the used oil will
 not interfere with the refining process
 (e.g., contaminants fouling a catalyst,
 etc.). Based on this, understanding,
 today's, exemption also applies to used
 oil that is introduced directly into the
 petroleum refining process at a point
 prior to crude distillation or catalytic
 cracking as long as the used oil
 comprises less than 1% of the crude oil
 feed to a petroleum refining facility
 process unit at any given time. Again,
because of the high ratio of crude oil to
 used oil, EPA considers these mixtures
to be equivalent to crude oil for
regulatory purposes. Therefore, the
Agency believes that this activity would
pose no significant increase hi risk.
  Used oil that is inserted directly into
the petroleum refining process (at a
volume of less than 1% of the crude oil
process; unit feed at any given time) is
considered mixed, and therefore exempt

-------
10554      Federal Register / Vol. 59, No.  43 / Friday, March 4, 1994  / Rules and Regulations
from part 279, at the point at which it
enters the process. This exemption
applies both to used oil generated at the
petroleum refining facility where the
used oil is being inserted, and to used
oil generated off-site that is collected
and transported to the petroleum
refining facility for insertion into the
refining process prior to crude
distillation or catalytic cracking.
  Used oil that is inserted into the
petroleum refining process without first
being mixed with crude oil feedstocks
(e.g. in crude oil stock tanks) is subject
to part 279 standards prior to insertion.
Used oil that is generated on-site and
then stored without prior mixing and
used oil generated on-site that
constitutes greater than 1%  of a mixture
of used and crude oil continues to be
subject to the part 279, subpart C
standards for generators. With the
exception of used oil that is exempt
from the part 279 standards because it
constitutes less than 1% of a mixture of
used oil and crude oil, used oil that is
generated off-site and then transported
to or stored at a petroleum refining
facility, continues to be subject to the
applicable part 279 requirements i.e., to
the requirements for used oil
transporters and transfer facilities while
being transported and to the
requirements for used oil processors
upon receipt at the petroleum refining
facility. Petroleum refining facilities that
receive used oil from off-site for direct
insertion into the petroleum refining
process are subject to the used oil
processor standards from the point at
which they receive the used oil up until
the point at which the used oil is
inserted into the petroleum refining
process. Finally, it is important to
reiterate that the exemptions provided
under both §§ 279.10(g)(2) and
279.10(g)(3) of today's rule  apply at the
point of mixing and only to mixtures
that contain less than 1% of used oil.
  Although petroleum industry
representatives have raised concerns
that a 1% limit on the amount of used
oil that can be inserted directly into the
petroleum refining process may be
technology limiting, EPA has not
received any information that would
support this position, nor has the
Agency received information to support
an alternative level. The Agency
believes that by limiting the amount of
used oil that can be introduced directly
into the refining process exempt from
the used oil processing standards, it can
better ensure against mixing only to
 avoid compliance with the part 279
processing standards. If information
becomes available that the  1% limit is
inhibiting used oil recycling, the
Agency will consider whether any
change to the rules is necessary.
  In the draft rule, EPA proposed to
regulate petroleum refining facilities
that receive used oil from off-site as
used oil transfer facilities prior to
mixing. However, EPA agrees with
comments on the draft rule that
petroleum refining facilities that receive
used oil from off-site pose the same
potential concerns associated with
receipt of adulterated used oil and
improper storage of used oil as used oil
re-refiners. Petroleum refining facilities
that receive used oil from off-site may
not have adequate information to ensure
that the used oil has not not been
improperly mixed with listed hazardous
waste. Also, the volumes of used oil that
may be managed require adequate
planning for dealing with emergency
releases. EPA has therefore revised the
final rule to provide that petroleum
refining facilities that receive and store
used oil from off-site are subject to.the
used oil processor standards prior to
mixing. The principal effect of this
change is that petroleum refiners that
receive used oil from off-site must
prepare a waste analysis plan to ensure
that the used oil has not been mixed
with hazardous waste and must
maintain an operating record to
document compliance with the waste
analysis plan. In addition, such
refineries will have to adopt or amend
emergency contingency plans to address
used oil in accordance with § 279.52  of
the used oil management standards.

4. Section 279.10(g)(4)—Used Oil
Inserted Into the Petroleum Refining
Process After Crude Distillation or
Catalytic Cracking
   Under § 279.10(g)(4) of today's rule,
used oil that is inserted into the
petroleum refining process after crude
distillation or catalytic cracking is
exempt from the part 279 standards
provided that the used oil meets the
used oil specification prior to insertion.
Used oil remains subject to part 279
standards up until its actual insertion
into the petroleum refining process. As
previously discussed, used oil generated
on-site must be stored according to part
 279, subpart C standards for used oil
generators. Used oil generated off-site
must be transported according to the
part 279, subpart E standards'for
transporters and transfer facilities and
 stored according to the  part 279, subpart
F standards for used oil processor/re-
refiners.
   EPA's use of the terms "before" and
 "after" crude distillation or catalytic
 cracking is intended to  distinguish
between the initial part of the petroleum
 refining process where  crude oil is the
primary feedstock and is refined by
undergoing crude distillation or
catalytic cracking and the latter part of
the petroleum refining process where
crude oil residuals constitute the
primary feed, and coke and asphalt are
the primary products. Refinery
processes that occur after crude
distillation or catalytic cracking do not
provide refining to the same extent as
that which occurs as a result of crude
distillation or catalytic cracking. Crude
distillation or catalytic cracking is
expressly designed to remove, alter, or
otherwise immobilize contaminants in
the normal course of the refining
process. EPA has insufficient
information on post-crude distillation or
catalytic cracking units identified by
commenters (e.g., asphalt towers,
petroleum cokers), and is concerned
about the possible  environmental effects
(e.g., air emissions, transfer of
inorganics to asphalt or petroleum coke)
of placing large amounts of off-
specification used oil into the petroleum
refining process without passing
through the crude  distillation or
catalytic cracking units. In contrast, on-
specification used oil may be burned in
the same manner as virgin petroleum
fuel in other situations, therefore it
makes little sense to restrict its use as
a feedstock to the petroleum coker (or in
any other process "after" crude
distillation or catalytic cracking).
   It should be noted that if off-
specification used oil is inserted into
petroleum refining processes after crude
distillation or catalytic cracking (e.g., a
coker), the facility would be subject to
the used oil processing requirements in
part 279, subpart F. In addition,
petroleum refining facilities that wish to
insert on-specification used oil into the  •
refining process after crude distillation
or catalytic cracking and that are the
first to claim that the used oil is on-
specification (whether generated at the
refinery, or at an off-site location),
would be defined  as marketers subject
to the requirements for used oil
marketers found in part 279, subpart H.

 5. Section 279.10(g)(5)—Used Oil
 Captured by the Refinery's Hydrocarbon
Recovery System or Wastewater
Treatment System and Inserted Into
 Petroleum Refining Process
   Section 279.10(g)(5) of today's rule
 exempts from the  part 279 standards
 used oil that incidentally enters and is
 recovered from a petroleum refining
 facility's hydrocarbon recovery system
 or its wastewater treatment system (e.g.,
 process sewer, storm sewer, or
 wastewater treatment units),  if the
 recovered used oil is subsequently
 inserted into the petroleum refining

-------
         '.    Federal Register / Vol.  59, No. 43 / Friday, March 4,  1994  /  Rules and Regulations      10555
process. Oil (that may contain small
amounts of used oil) that has been
recovered from a refining facility's
hydrocarbon recovery or wastewater
treatment system is typically used as a
feedstock in petroleum refining to
produce more petroleum products. EPA
understands that used oil, generated
from routine refinery process operations
and that incidentally enters a refinery's
recovery lor wastewater treatment
system (e.g., drips, leaks, and spills from
compressors, valves, and pumps),
represents a small portion of the total oil
that enters (and is then recovered from)
the recovery or wastewater treatment
system. Thus, the oil recovered from the
system is; more properly characterized
as crude feedstock than used oil.
Providedjthe used oil is inserted into
the petroleum refining process, EPA
believes that regulation under part 279
standards is unwarranted. This
exemption from the part 279 standards
does not extend to used oil which is
intentionally introduced into a
petroleum refinery's recovery or
wastewater treatment system (e.g.,
pouring collected used oil into any part
of the hydrocarbon recovery system,
storm or process sewer system or into
wastewater treatment units). Used oil
may not be introduced to the refinery's
hydrocarbon recovery or wastewater
treatment system as a way to avoid
meeting the conditions specified in
§ 279.lO(gK4).
  For the purposes of the exemption in
today's nile, the examples cited in the
existing cle minimis wastewater
exclusion (§ 279.10(f)) provide guidance
on what types of releases to a refinery's
hydrocarbon recovery or wastewater
treatment system would be considered
"routine" or "incidental". The
exemption is intended to cover losses
from drippage, minor spillage, etc., that
cannot bej reasonably avoided. For
example, jused oil that has been
collected ifrom equipment or vehicle
maintenance activities and intentionally
introduced into a refinery's wastewater
treatment; system would not be exempt
under § 279.1(g)(5) from the part 279
standards once recovered. Similarly,
used oil that is generated off-site and is
brought to the refinery may not be
added to any portion of the refinery's
wastewater treatment system (i.e.,
process sewer, storm sewer, or
wastewater treatment units), and still be
exempt under § 279.10(g)(5) once
recovered; such oil is clearly not
"incidentally captured" by the
refinery'sjwastewater treatment system.
In fact, unless  specifically exempted
under § 279.10(g)(2) or § 279.10(g)(3) of
today's rule, this type of activity would
meet the definition of used oil
processing under the existing used oil
management standards (see 40 CFR
279.1).                    :
  Today's rule does not preclude
intentional introduction of used oil in to
the facility's recovered oil tanks. EPA is
aware that used oil from both on- and
off-site is often added directly to the
petroleum refining facility's recovered
oil tanks. Mixtures of used oil and
recovered oil that contain greater than
1% used oil are regulated as used oil.
Mixtures of used oil and recovered oil
that contain less than 1% used oil and
are inserted into the petroleum refining
process prior to crude distillation or
catalytic cracking are exempt from the
part 279 used oil management standards
under § 279.10(g)(2). Mixtures of used
oil and recovered oil that contain less
than 1% used oil and are inserted into
the petroleum refining process after
crude distillation or catalytic cracking
are exempt from the part 279 standards
(under § 279.10(g)(4)) only if the used
oil meets the used oil specification prior
to mixing with recovered oil.

6. Section 279.10(g)(6)—Stock Tank
Bottoms
  Section 279.10(g)(6) of today's rule
exempts tank bottoms from stock tanks
containing exempt mixtures of used oil
and crude oil from the part 279
standards. Like the actual mixtures of
used oil and crude oil, the bottoms from
these mixtures are expected to contain
insignificant amounts of used oil.
Therefore, the Agency does not believe
that the bottoms from tanks (or other
units) containing mixtures of used oil
and crude oil should be subject to the
used oil management standards. The
tank bottoms are subject to all other
applicable requirements, i.e., the
§ 262.11 requirement to determine if
they are hazardous waste.

D. Used Oil Transportation

Section 279.1—Definition of Transfer
Facility
  Today's rule revises the definition of
transfer facility to allow used oil to be
held at a location (i.e., a transfer facility)
temporarily prior to activities that are
not subject to the processor standards as
a result of today's rulemaking. In the
September 10,1992 final rule, a transfer
facility was defined as a transportation-
related facility where shipments of used
oil are held for more than 24 hours but
less than 35 days during the normal
course of transportation. Today's rule
expands that definition to allow used oil
to be held for more than 24 hours but
less than 35 days during the normal
course of transportation or prior to an
activity performed pursuant to
§ 279.20(b)(2). Under the amended
definition, as discussed below in section
F of this preamble, a site to which used
oil from oil-bearing electrical
transformers is transported for filtering
prior to reuse would be considered a
transfer facility under today's definition.

E. Section 279.20(b)(2)(ii)—Used Oil
Processing by Generators and Transfer
Facilities
  Since the promulgation of the
September 10,1992, Used Oil
Management Standards, a number of
parties have raised concerns regarding
the definition of used oil processor and
the types of activities that are covered
by that definition. The commenters are
concerned that a broad construction of
the teirm processor inappropriately
includes a number of very basic on-site
generator activities that the Agency did
not intend to regulate under the used oil
processor standards (e.g.
reconditioning/maintenance to extend
the life of used oil, separation of used
oil from wastewater discharge, etc.).
EPA agrees that activities such as these,
when performed by the generator, were
not intended to be covered under the
used oil processor standards because
used oil processing is not their primary
purpose, as explained below in greater
detail. In fact, too broad an
interpretation of the processor
definition may discourage
environmentally beneficial recycling
and waste minimization activities by
imposing an unwarranted regulatory
burden on owners and operators that
EPA did not intend to regulate as used
oil processors.
  Therefore, today's rule revises the
used oil management regulations to
clarify the Agency's intent regarding the
definition of a used oil processor by
specifying those on-site maintenance,
filtering, and separation activities that
are not, and were not intended to be
subject to the used oil processing
standards. Under today's rule,
generators 1 who only handle used oil in
a manner specified under
§ 279.20(b)(2)(ii) are not processors
provided that the used oil is generated
on-site and is not being sent directly off:
site to a burner of on- or off-
specification used oil fuel. (Section
279.2CI(b)(2)(ii) also applies to collection
  i A used oil generator is any person, by site,
whose act or process produces used oil or whose
act first causes used oil to become subject to
regulations. For example, generators include all
persons and businesses who produce used oil
through commercial or industrial operations and
vehicle (services, including government agencies,
and/or persons and businesses who collect used oil
from households and "do-it-yourself oil changes.

-------
10556      Federal Register / Vol. 59, No.  43 / Friday, March  4,  1994 /Rules andRegulations
centers and aggregation points since
these entities are regulated as
generators.)
  Activities that EPA did not intend to
include under the definition of used oil
processor are described below. EPA
does not believe that the activities
identified in § 279.20(b)(2)(ii) should be
subject to the used oil processor
standards because used oil processing is
not the primary purpose of these
activities i.e., the primary purpose of
these activities is not to produce from
used oil or to make it more amenable for
the production of used oil derived
products, and the Agency does not
expect these limited activities will pose
the same kinds of environmental
problems that may occur at processor
facilities. Instead, in these cases, the act
of mixing, filtering, separating, draining
etc., used oil by the generator
constitutes a basic step that is incidental
or ancillary to a primary activity which
is distinct from used oil processing. It is
important to note, however, that owners
or operators who generate used oil as a
result of any of the activities specified
in § 279.20(b)(2Xii) are considered used
oil generators and are subject to the
generator standards in subpart C.
  EPA is allowing on-site but not off-
site burning of used oil generated from
designated on-site activities because the
Agency believes that this approach best
enables EPA to strike a reasonable
balance between encouraging beneficial
on-site reuse and recycling activities
that should pose very limited risks, on
one hand, and ensuring that activities
undertaken primarily to make used oil
more amenable for burning (i.e., used oil
processing) are adequately controlled
under the more stringent used oil
processing standards.
  The definition of a used oil processor
is based on the purpose for which used
oil is being filtered, separated, or
otherwise reconditioned (i.e., whether
the activity is designed to produce used
oil derived products or to make used oil
more amenable for the production of
used oil derived products). The Agency
is concerned that in situations where
used oil is being filtered, separated or
otherwise reconditioned and then sent
to off-site burners, the purpose of the
activity may prove difficult to discern
and that consequently,  § 279.20(b)(2)(ii)
provisions may be used as a means to
avoid compliance with the used oil
processor standards (i.e., by persons
who claim not to be used oil processors
under the § 279.20(b)(2)(ii) provisions
but whose primary purpose is to make
the used oil more suitable for burning).
Therefore, EPA believes it is necessary
to adopt an objective measure of the
purpose of the activity. The Agency
believes that a prohibition against
sending used oil generated from
specified on-site activities to off-site
burners provides the most practical and
effective way to ensure that activities
undertaken only to make used oil more
amenable for burning are subject to the
used oil processor standards.

1. Definition of Used Oil Processor
  (A) Reconditioning used oil before
returning it for reuse by the generator.
Under today's rule facility owners or
operators who clean, separate, or
otherwise recondition used oil
generated on-site and then reuse it are
not considered used oil processors,
provided that the reconditioned used oil
is being reused by the owner or operator
who generated it. Examples of activities
covered under this category include
filtering of metalworking fluids for
reuse, and filtering and then replacing
oil from oil-bearing transformers and
turbines during routine maintenance.
  Most manufacturing facilities have in
place central filtration systems designed
to remove contaminants from and
extend the life of water-soluble metal
working fluids (e.g., lubricants and
coolants), used in machining, _
and boring equipment. These filtration
systems are on-site systems that filter
chips, metal fines, dirt, water, and other
contaminants from cutting fluids,
drawing lubricants and coolants used in
machining operations. The filtration of
these extraneous materials is designed
to extend the life of the reusable
coolants and lubricants and is
incidental to the production process.
Today's rule clarifies that this type of
filtration activity is not subject to the
used oil processing standards when the
generator reuses the filtered oil.
  Similarly, during regularly scheduled
maintenance of oil-bearing transformers
and turbines, the oil in the electrical
equipment is removed so that repairs/
maintenance can be performed. In some
instances, the oil is filtered prior to
replacement. The filtering of the used
oil is done to extend the life of the used
oil, not because the oil is no longer
useful, and is therefore ancillary to the
equipment repair and maintenance.
While, under today's rule, the owner or
operator would not be considered a
processor in these cases, the draining of
the used oil from the transformer
constitutes generation of used oil so that
the facility would be considered a used
oil generator.
  The Agency is aware that not all used
transformer oil is drained and filtered in
the field. Instead, the  oil-bearing
electrical equipment may be transported
to a central location where the oil is
removed, filtered, and replaced. Or, the
used oil may be removed from the
transformers or turbines in the field and
then transported separately in a tanker
truck to a central location where it is
filtered and put back into electrical
equipment. Under today's rule, in cases
where electrical equipment containing
used oil is transported to a central
location, the transporter of the oil
bearing electrical equipment would not
be considered a used oil transporter.
However, the owner or operator would
become a generator at the point at which
the used oil is drained from the
equipment (i.e., at the site where the oil
is drained and filtered).
  In cases where the used oil is
removed from the transformers or
turbines in the field and then
transported separately in a tanker truck
to a central location for filtering prior to
replacement into electrical equipment,
the owner or operator would become a
generator in the field (i.e., at the point
at which the used oil is drained). The
person who then transports the used oil
would also be considered a used oil
transporter subject to the transporter
standards. In these cases, the location at
which the used oil is filtered would be
considered a used oil transfer facility
subject to the transfer facility standards
in § 279.45, provided that the used oil-
is stored at the site for more than 24
hours and less than 35 days. If the used
oil is filtered within 24 hours of being
drained (i.e., during transport) only the
part 279 standards for used oil
transporters would apply. This filtering
activity should not raise the kind of
environmental concerns that would be
present at used oil processors;
essentially, the filtering is incidental to
the transportation and storage and
should not change a facility's regulatory
status. As discussed in more detail
below, today's rule provides that
transporters of used oil that is removed
from electrical transformers and
turbines and filtered by the transporter
or at a transfer facility prior to being
returned to the same use are not subject
to the processor or re-refiner
requirements in subpart F. In
accordance with § 279.10(e), once the
used oil has been reclaimed to the point
where it is ready for reuse without
further processing, it is not subject to
regulation as used oil.
  (B) Separating used oil from
wastewater to make wastewater
acceptable for discharge or reuse.
Today's rule clarifies that oil/water
separation activities designed to make
wastewater acceptable for discharge or
reuse are not subject to the used oil
processor standards. Facilities often use
oil/water separators to remove oil
(which may contain used oil) from oil/

-------
             Federal Register / Vol.  59, No. 43  /  Friday,  March 4, 1994 / Rules and Regulations
                                                                     10557
 water mixtures collected from the
 facility's storm sewer, process sewer,
 sumps and other wastewater
 containment areas. These separation
 systems use chemical and physical
 methods to break the oil/water emulsion
 and recover oil from the wastewater in
 order to make the wastewater or storm
 water acceptable for discharge or reuse
 in compliance with local, state and
 federal regulations.
  This type of pretreatment of
 wastewater containing oil is designed
 primarily to ensure that the wastewater
 meets established limits for water
 discharge to streams and POTWs, and
 not to produce used oil derived
 products or to make used oil more
 amenable for the production of used oil
 derived products. This type of oil/water
 separation activity is therefore not
 subject to the used oil processor
 standards as clarified under today's
 rule. It should be noted, however, that
 any used oil recovered from separator
 units would be subject to the used oil
 generator standards. It is also important
 to note that this provision applies only
 to used oil; that is generated on-site. The
 provision would apply, for example, to
 simple oil 'water separation activities
 conducted, (for purposes of wastewater
 discharge) ;by a used oil processor on
 wastewater which has been generated
 by that processor. However, persons
 who perform oil/water separation
 activities on oily wastewater received
 from off-site would be considered used
 oil processors.
  1C) Using oil mist collectors to remove
 droplets of used oil from in-plant air to
 make plant air suitable for continued
recirculation. As clarified under today's
rule, the act of removing used oil from
 ambient air in the workplace is not
 subject to the used oil processor
 standards. |At manufacturing facilities,
 droplets of used oil from machining
 operations,1 are often dispersed into in-
plant air. Oil mist collectors physically
remove the small droplets of oil present
in the ambient air. This activity is not
subject to the used oil processing
standards because it is intended
primarily to make plant air suitable for
continued recirculation and not to
produce products from used oil or to
make it more amenable for the
production of used oil derived products.
However, the oil removed from oil mist
collectors is subject to the used oil
generator standards.
  (D) Removing used oil from materials
containing or otherwise contaminated
with used oil in order to remove
excessive oil. Under § 279.10(c) of the
used oil standards, materials containing
or otherwise contaminated with used oil
from which the used oil has been
 properly drained or removed to the
 extent possible such that no visible
 signs of free-flowing oil remain in or on
 the material are not used oil except
 when burned for energy recovery.
 Today's rule clarifies that the Agency
 does not consider the removal of used
 oil from materials containing or
 contaminated with used oil in order to
 remove excess oil in accordance with
 § 279.10(c) to be used oil processing.
 The production of used oil derived
 products is clearly not the primary
 reason for removing used oil from
 materials containing or contaminated
 with used oil. Instead, the activity is
 conducted primarily to clean the
 materials (e.g., machine tools, scrap
 metal, etc.) prior to reuse, recycling, or
 disposal and is therefore not subject to
 the used oil processing standards as
 clarified by today's rule. However, in
 removing the used oil from the
 materials, the owner or operator
 becomes a used oil generator subject to
 the Subpart C used oil generator
 standards.
  (E) Filtering, separating, or otherwise
 reconditioning used oil before burning it
 in a space heater. Under § 279.23 of the
 used oil standards, used oil may be
 burned in a used oil-fired space heater
 under specified conditions, and
 provided that the space heater burns
 only used oil that the owner or operator
 generates and/or used oil obtained from
 household DIY oil changers. Prior to
 burning, the used oil must often be
 filtered to remove impurities. Today's
 rule clarifies that filtering of used oil for
 the purpose of removing contaminants
 prior to burning the used oil in a space
 heater is not considered processing of
 used oil.
  EPA provided a regulatory exemption
 from the used oil burning standards for
 generators who burn used oil in on-site
 space heaters (in accordance with
 § 279.23) because the Agency believes
 that burning of small amounts of used
 oil in space heaters poses insignificant
 risks due to the small volume of used oil
 burned (see 50 FR 49194, Nov.  29,
 1985). The Agency believes that,
 because of the small volumes of used oil
 involved, filtering, separating, or
 otherwise reconditioning used oil that is
 generated on-site prior to burning it in
 a space heater would also not pose
 significant risk. Therefore, although the
 purpose of the filtering activity in this
 case is to make the used oil more
 amenable for burning, because of the
 small amounts of used oil being filtered
 for this purpose, the Agency does not
believe that imposition of the used oil
 processor standards is warranted. EPA
is therefore adding a regulatory
clarification (§ 279.20(b)(2)(ii)(F)) that
the used oil processor standards do not
apply to filtering of used oil prior to
burning it in a space heater, provided
that the) used oil is generated on-site or
obtained from households or "do-it-
yourself oil changes.
  F. Section 279.41—Restrictions on
transporters who are not also processors
or re-refiners and changes to the
definition of transfer facility.
  Today's rule amends § 279.41 to
provide that transporters of used oil that
is removed from oil-bearing
transformers and turbines and filtered
by a transporter or at a transfer facility
before being returned to its original use
are not  subject to the used oil processor -
and re-refiner requirements. As
previously discussed, during routine
maintenance of oil-bearing transformers
and turbines (or similar equipment), the
oil in the electrical equipment is
removed so that repairs/ maintenance
can be performed. In some cases, the
used oil is removed from the
transfoirmers or turbines in the  field and
then transported separately in a tanker
truck (subject to the used oil transporter
standards) to a central location where it
is filtered and put back into electrical
equipment. As discussed above, under
today's  rule the filtering of the used oil
would mot be considered used oil
processing provided that the filtered oil
is reused in the same or similar manner.
And, in. these cases (i.e., where the used
oil is removed from the equipment and
transported to a separate location for
filtering), the location at which the oil
is filtered would be considered a
transfer facility provided that the used
oil is stored for more than 24 hours and
less than 35  days. If, as sometimes
occurs,  the used oil is filtered within 24
hours of being stored at the central
location (i.e., during transport)  the only
applicable standards would be the part
279 standards for used oil transporters
(i.e., the § 279.45 requirements  for used
oil storage at transfer facilities would
not apply).
  Section 279.41(c) of today's rule
provider conforming changes to the
used oil transportation standards to
allow transporters or transfer facilities
to filter  the used oil without being
subject to the used oil processor
standards. It should be clearly noted,
however, that if the used oil is stored at .
a site for more than 35 days, greater
environmental concerns may be present,
so the site would no longer be
considered a transfer facility and  the
processor standards would apply.
  In addition, this rule expands the
definition of transfer facility to  allow
used oil to be held at a location (i.e., a
transfer  facility) temporarily prior to
activities that are exempt from or

-------
10558      Federal Register / Vol.  59,  No. 43  /  Friday,  March 4,  1994  /  Rules and Regulations
performed pursuant to the part 279
standards as a result of today's
rulemaking. Under today's revised
definition, used oil can be held at a
transfer facility for more than 24 hours
but less than 35 days prior to an activity
and performed pursuant to
§ 279.20(b)(2). As a result of this change,
a site where used oil that has been
drained from oil-bearing transformers
and turbines is held for more than 24
hours and less than 35 days prior to
being filtered for reuse would be
considered a transfer facility.
  G. Section 279.46— Tracking Today's
rule revises the § 279.46 tracking
requirements as they apply to rail
transporters. Under amended § 279.46, a
signature is not required on records of
acceptance or records of delivery of
used oil shipments that are exchanged
between  rail transporters. The Agency is
making this change in response to
comments submitted by the railroad
industry  regarding the impracticability
of requiring signed receipts when used
oil is transferred from one rail
transporter to another. EPA is aware that
rail cars are typically transferred from
one railroad company to another
without the face-to-face contact that
occurs in, for example, the motor carrier
industry. The Agency also recognizes
that, unlike non-rail transporters,
railroads rely on sophisticated
electronic tracking and information
systems for recording rail-to-rail transfer
of cargo. Given these unique
circumstances, and in light of the fact
that 40 CFR 263.20(f) regulations for
hazardous waste transporters do not
include signature requirements for
intermediate rail carriers, EPA agrees
that the signature requirements are
unduly burdensome and unnecessary
when applied to intermediate used oil
rail transporters. EPA is therefore
revising  the used oil regulations to
eliminate the § 279.46 signature
requirements between intermediate rail
carriers.
H. Corrections to the Regulatory
Language
1. Requirements for Enforcement
Authority
  The Agency published a correction
notice on May 3,1993, which amended
several sections of the part 279 used oil
management standards that were
originally promulgated on September
10,1992. In the May 3,1993, correction
notice, EPA incorrectly amended
regulatory § 271.16, that addressed the
requirements for States to have adequate
criminal enforcement authority for
hazardous waste. EPA amended the
regulation to include enforcement
authority for used oil handlers that
manage used oil incorrectly, but EPA
inadvertently deleted from § 271.16
enforcement authority for the improper
management of hazardous waste.
Therefore, today's rule corrects this
section to include enforcement
authority for the improper management
of both hazardous waste and used oil.
2. Rebuttable Presumption

  The final used oil regulations
published on September 10,1992, allow
persons to rebut the presumption that
used oil containing more than 1,000
ppm total halogens is a hazardous waste
by using an analytical method from
SW-846, Third Edition, to show that the
used oil does not contain  hazardous
waste. In the regulations, the Agency
provided information on the cost of
SW-846, Edition III and how to obtain
it. However, the Agency misquoted the
cost of the document. The actual cost
was $319.00 rather than $110.00 as
quoted throughout the September 10,
1992, regulations. To avoid having to
amend the regulations as a result of
future changes in the cost of the
document, the Agency is deleting
reference to the cost of SW-846, Edition
III from the used oil regulations.

3. Characteristic Hazardous Waste

  Today's rule revises § 279.10(b)(2)(iii)
by deleting reference to the listing status
(under part 261, subpart D) of a
hazardous waste that is mixed with
used oil. This change is necessary to
correct a contradiction in the
regulations regarding applicability of
the used oil management standards to
mixtures of used oil and hazardous
waste that is listed in subpart D solely
because it exhibits one or more of the
characteristics of hazardous waste
identified in subpart C. In technical
corrections to the used oil management
standards published on May 3,1993, (57
FR 26420), EPA amended § 279.10(b)(2)
to correct an error in the September 10,
1992, standards regarding how these
mixtures are regulated. At that time,
conforming changes should have been,
but were not made to § 279.10(b)(2)(iii).
As amended by today's rule,
§ 279.10(b)(2)(iii) correctly provides  that
mixtures of used oil and hazardous
waste that solely exhibits one or more
hazardous waste characteristic and
mixtures of used oil and hazardous
waste that is listed in subpart D solely
because it exhibits one or more subpart
C hazardous characteristics are
regulated as used oil if the mixture is of
used oil and a waste which is hazardous
solely because it exhibits the
characteristic of ignitability and the
resultant mixture does not exhibit the"
characteristic of ignitability.
IV. State Authorization

  As explained in the preamble to the
May 3,1993, Technical Correction to
the September 10,1992, rule, EPA is
treating the majority of the final used oil
management standards in the same
manner as "non-HSWA" Subtitle C
requirements. The used oil management
standards became effective on March 8,
1993, only in those States and
Territories that do not have RCRA base
program authorization and on Indian
lands. States are required to revise their
Subtitle C base programs to adopt the
new used oil requirements (including
those promulgated in today's rule) by
July 1,1994, or by July 1,1995, if a
statutory change is necessary. See 58 FR
26420 and 57 FR 41605.
  Authorized States are only required to
modify their programs when EPA
promulgates Federal standards that  are
more stringent or broader in scope than
the existing Federal standards. Section
3009  of RCRA allows States to impose
standards more stringent than those in
the Federal program. For those Federal
program changes that are less stringent
or reduce the scope of the Federal
program, States are not required to
modify their programs. See 40 CFR
271.1(k). Except for the amendments
made to § 279.20(b), the standards
promulgated today are less stringent
than or reduce the scope of the existing
Federal requirements. The amendments
made to § 279.20(b) merely provide
clarification of the existing used oil
regulations and are therefore not
considered to be less stringent than the
current Federal program. Therefore,
with  the exception of the provisions
added at § 279.20(b)(2)(i), authorized
States would not be required to modify
their programs to adopt requirements
equivalent to or substantially equivalent
to the provision listed above.

V. Executive Order 12866

   Under Executive Order 12866, 58 FR
51735 (October 4,1993) the Agency
must determine whether the regulatory
action is "significant" and therefore
subject to OMB review and the
requirements of the Executive Order.
The Order defines "significant
regulatory action" as one that is likely
to result in a rule that may: (1) Have an
annual effect on the economy of $100
million or more or adversely affect  in a
material way the economy, a sector of
the economy, productivity, competition,
jobs, the environment, public health or
safety, or State, local, or tribal
governments or communities;

-------
             Federal Register / Vol. 59, No.43 /Friday,  March 4, 1994 / Rules and Regulations      10559
   (2) Create a serious inconsistency or
otherwise interfere with an action taken
or planned by another agency;
   (3) Materially alter the budgetary
impact of entitlements, grants, user fees,
or loan programs or the rights and
obligations of recipient thereof; or
   (4) Raise novel legal or policy issues
arising out of legal mandates, the
President's priorities, or the principles
set forth in the "Executive Order."
   OMB has exempted this regulatory
action from E.0.12866 review.
VI. Paperwork Reduction Act
   The reporting and recordkeeping
requirements of part 279 have been
approved by OMB and generally
assigned ithe control number 2050-0124
(See 58 FR 34374 (June 25,1993)),
which remains in effect. As today's rule
does not impose any new such
requiremjents, a separate information
collection request was not prepared.
VII.  Regulatory Flexibility Act
   Today's rule does not impose any new
regulatory requirements, and indeed,
decreases the costs of compliance for a
number of facilities. I therefore certify
that  today's rule will not have a
significant impact or a substantial
number of small entities.
VIII. Administrative Procedures Act
   Today's rule takes final action on
EPA's  1985 and 1991 proposals to
exempt used oil inserted into primary
refining processes from the used oil
management standards. EPA did not
address these issues in its September 10,
1992, final rule, and therefore those
proposals remained outstanding until
today's rule. Since these issues were
fully addressed in those proposals,
further public comment on today's rule
is unnecessary. The other changes being
made in today's rule either correct
errors or clarify the language contained
in the September 10,1992 rule. No
comment is necessary on these
provision's.
