Protection of Stratospheric Ozone

AGENCY: Environmental Protection Agency.

ACTION: Final rule.
SUMMARY: This final rule establishes standards and requirements 
for servicing of motor vehicle air conditioners, and restricts 
the sale of small containers of ozone-depleting substances, 
under section 609 of the Clean Air Act, as amended (Act).
Specifically, 
the regulations require persons who repair or service motor 
vehicle air-conditioning units for consideration to be certified 
in refrigerant recovery and recycling and to properly use approved 
equipment when performing service involving the refrigerant. 
Finally, effective November 15, 1992, the regulations prohibit 
the sale of containers of ozone depleting substances under 20 
pounds except to certified technicians.
DATES: This final regulation is effective August 13, 1992.


   Note: Under Section 307(b)(1) of the Clean Air Act, EPA hereby 
finds that these regulations are of national applicability. 
Accordingly, judicial review of this action is available only 
by the filing of a petition for review in the United States 
Circuit Court of Appeals for the District of Columbia Circuit 
within 60 days of publication. Under Section 307(b)(2) of the 
Act, the requirements that are the subject of today's notice 
may not be challenged later in judicial proceedings brought 
by EPA to enforce these requirements.

I. Background


A. Statutory Authority

   Section 609 of the Act requires the Administrator to promulgate 
regulations establishing standards and requirements regarding 
the servicing of motor vehicle air conditioners. This section 
also prohibits the sale of small containers of ozone depleting 
substances, except to certified technicians. Title VI of the 
Act is designed to protect the stratospheric ozone layer.

B. Ozone Depletion

   The stratospheric ozone layer protects the earth from the 
penetration of ultraviolot (UV-B) radiation. A national and 
international consensus exists that chlorofluorocarbons (CFCs), 
halons, carbon tetrachloride and methyl chloroform must be
restricted 
because of the risk of depletion of the stratospheric ozone 
layer through the release of chlorine and bromine. To the extent 
depletion occurs, penetration of UV-B radiation increases,
resulting 
in potential health and environmental harm including increased 
incidence of certain skin cancers and cataracts, suppression 
of the immune system, damage to plants including crops and aquatic 
organisms, increased formation of ground-level ozone and increased 
weathering of outdoor plastics. (See 53 FR 30566, August 12, 
1988 for more information on the effects of ozone depletion.)
   The original theory linking CFCs to ozone depletion was first 
proposed in 1974. Since then, the scientific community has made 
remarkable advances in understanding atmospheric processes
affecting 
stratospheric ozone science. Model predictions in the late 1980s 
suggested that continued use of CFCs would lead to substantial 
ozone depletion in the middle of the next century. Despite the 
sophistication of these models, scientists were unable to predict 
the extent of the decrease in stratospheric ozone over Antarctica 
that was first reported in 1985. This seasonal loss of ozone 
over the south pole became known as the "Antarctic ozone hole". 
In 1988, the results of an international assessment of ozone 
trends were published in the Executive Summary of the Ozone 
Trends Panel Report. In addition to the ozone hole, this report 
stated that analysis of total-column ozone data showed measurable 
downward trends from 1969 to 1988 of 3 to 5 percent in the northern

hemisphere in the winter. In early 1991, new scientific evidence 
indicated an annual loss of stratospheric ozone over the northern 
mid-latitudes during the past decade of 3 to 5 percent. This 
amount is 2 times greater than past studies suggested and
illustrated 
the concern that ozone depletion appears to be occurring faster 
than theoretical models had predicted. The latest scientific 
assessment showed for the first time stratospheric ozone depletion 
in summertime over the continental United States.

C. Montreal Protocol

   In September 1987, the United States and 22 other countries 
signed the Montreal Protocol on Substances that Deplete the 
Ozone Layer. As originally drafted, the Protocol called for 
production and consumption of CFCs (CFC-11, 12, 113, 114, 115) 
and Halon-1211, -1301 and -2402 to be frozen at 1986 levels 
beginning July 1, 1989 and January 1, 1992 respectively, and 
for the CFCs to be reduced to 50 percent of 1986 levels by 1998. 
To date, 75 nations representing well over 90% of the world's 
production capacity have signed the Montreal Protocol. EPA
promulgated 
regulations implementing the requirements of the 1987 Protocol 
through a system of tradable allowances (53 FR 30566, August 
12, 1988). EPA apportioned the allowances to producers and
importers 
of ozone depleting substances (controlled substances) based 
on their 1986 level of production and importation. It then reduced 
the allowances for the controlled substances according to the 
schedule specified in the Protocol.

D. Excise Tax

   As part of the Omnibus Budget Reconciliation Act of 1989, 
the U.S. Congress levied an excise tax on the sale of CFCs and 
other chemicals that deplete the ozone layer, with specific 
exemptions for exports and recycling. The tax has operated as 
a complement to EPA's regulations limiting production and
consumption 
by increasing the costs of using virgin controlled substances. 
As a result of the tax, there is an added incentive for industry 
to shift out of controlled substances and to increase recycling 
activities. The tax has also stimulated the market for alternative 
chemicals and processes. The original excise tax was amended 
in 1991 to include methyl chloroform, carbon tetrachloride and 
other CFCs regulated by the amended Montreal Protocol and title 
VI of the Clean Air Act.

E. London Amendments

   Since the signing of the Protocol in 1987, additional scientific

evidence became available indicating that depletion of the
stratospheric 
ozone layer was occurring more quickly than had been anticipated. 
In response to this evidence (i.e. the 1988 Ozone Trends Panel 
Report), the Parties to the Protocol at their meeting in London 
in June 1990 amended the Protocol schedule for CFCs and halons 
to require a complete phaseout by January 1, 2000. Methyl
chloroform 
and carbon tetrachloride were added to the list of ozone depleting 
substances, with carbon tetrachloride phased out by January 
1, 2000 and methyl chloroform phased out by January 1, 2005.
   The parties also passed a non-binding resolution regarding 
the use of hydrochlorofluorocarbon (HCFCs). HCFCs have been 
identified as interim substitutes for CFCs because they add 
much less chlorine to the stratosphere than fully halogenated 
CFCs. The Parties were concerned, however, that rapid growth 
in the amount of use of these chemicals over time would still 
pose a threat to the ozone layer. As a result, the resolution 
calls for the phaseout of HCFCs by 2020 if feasible and no later 
than 2040 in any case.

F. Advance Notice of Proposed Rulemaking

   On May 1, 1990, EPA published an advance notice of proposed 
rulemaking (ANPRM, 55 FR 18256) addressing issues related to 
the development of a national recycling program. This notice 
emphasized that in addition to delaying or reducing the release 
of ozone depleting substances, recycling is important for avoiding 
the cost of early retirement or retrofit of equipment requiring 
CFCs for service past the year in which production is eliminated. 
Although the Agency continues to investigate destruction of 
these chemicals, at this time it believes that continuing to 
use these substances through recycling in existing equipment 
can serve as a useful bridge to alternative products while
minimizing 
disruption in the utilization of the current capital stock of 
equipment, preventing costly early retirement of equipment.
   The ANPRM asked for comment on the feasibility of recycling 
in various CFC end uses and also asked for comment on methods, 
such as a deposit/refund system, that could be employed to further 
enhance recycling. The Agency received 110 public comments in 
response to the ANPRM. In general, most commenters recognized 
the need for recycling to help efforts to protect the ozone 
layer and to provide a source of supply to service existing 
capital equipment past the end of production.
   The ANPRM also described the cooperative project undertaken 
between EPA, the Mobile Air Conditioning Society, the Motor 
Vehicle Manufacturers Association (MVMA), the Automotive Importers 
of America, the Society of Automotive Engineers (SAE), the American

Society of Heating, Refrigerating, and Air-Conditioning Engineers, 
Inc. (ASHRAE), manufacturers of recover/recycling equipment, 
automotive industry representatives, and environmental groups 
to develop recycling of motor vehicle air conditioning refrigerant.

This group participated in projects that led to the development 
of a purity standard for recycled refrigerant for motor vehicles 
(SAE J1991), a service procedure standard (SAE J1989), and a 
standard for the recycling equipment (SAE J1990). For a more 
detailed discussion of the voluntary program, see the NPRM
published 
September 4, 1991 (56 FR 43842).

G. Clean Air Act Amendments of 1990

   The Clean Air Act Amendments of 1990, signed November 15, 
1990, include requirements for controlling ozone-depleting
substances 
which are generally consistent with, but in some cases more 
stringent than those contained in the revised Montreal Protocol. 
For the substances covered by the revised Protocol's control 
measures ("class I" substances including fully halogenated CFCs, 
Halons, methyl chloroform, and carbon tetrachloride), title 
VI of the Act calls for a phase-out by January 1, 2000 with 
deeper interim reductions and, in the case of methyl chloroform, 
an earlier phaseout date (2002 instead of 2005). For the HCFCs 
("class II" substances), title VI requires use restrictions, 
a production freeze in 2015 and a phaseout in 2030. EPA issued 
a temporary final rule on March 6, 1991 implementing the production

and consumption limits contained in the Act for calendar year 
1991. (See 56 FR 9518.) The Agency published proposed regulations 
for 1992 and beyond on September 30, 1991 (See 56 FR 49548).
   In addition to the phaseout of ozone depleting substances, 
title VI includes provisions to reduce emissions of all ozone-
depleting substances. Section 608 contains requirements for 
EPA to promulgate a regulation to achieve a "lowest achievable 
level" of emissions of controlled substances during use and 
disposal of appliances and industrial process refrigeration 
and bans intentional venting at service and disposal. Section 
609, which today's notice implements, requires standards for 
certification of technicians and for equipment used in the
servicing 
of motor vehicle air conditioners and restricts the sale of 
small containers of CFCs. A nonessential products ban and mandatory

labeling are required in sections 610 and 611, respectively, 
and a program to review the safety of alternatives to controlled 
substances is required under section 612.

H. September 4, 1991 Proposed Rule and April 22, 1992 Supplemental 
Proposal

   In a notice of proposed rulemaking published on September 
4, 1991 (56 FR 43842), EPA discussed many of the important issues 
surrounding implementation of Section 609 of the Act. The proposal 
discussed various requirements, all designed to limit the release 
of refrigerant during the service of motor vehicle air
conditioners. 
The following is a short description of the major components 
of the September 4 Notice.
   EPA proposed definitions for the terms "motor vehicle," "motor 
vehicle air conditioner," "service for consideration," "service 
involving refrigerant," "approved refrigerant recycling equipment,"

and "properly using." These proposed definitions would apply 
only to regulations under section 609. In describing these
definitions, 
EPA discussed the legal and policy aspects of the various options 
considered.
   With respect to approved refrigerant recycling equipment, 
EPA proposed approval of two kinds of equipment-equipment that 
recovered and recycled the refrigerant, and equipment that only 
recovered the refrigerant. Standards for approval of
recovery/recycle 
equipment were proposed in appendix A of the proposal. These 
standards consisted of the two SAE standards specifically mentioned

in the Act (SAE J1990, SAE J1989). They contain appropriate 
service procedures for recycling refrigerant in motor vehicles, 
and equipment specifications for recover/recycle machines. Appendix

A also contained the SAE standard of purity for refrigerant 
recycled on-site at a service establishment (SAE J1991).
   Appendix B was reserved for the technical standard for recover 
only equipment. Proposed appendix B was published in a supplemental

notice dated April 22, 1992 (57 FR 14763). This proposed standard 
closely resembles another SAE standard (SAE J2209) written
specifically 
for equipment that removes refrigerant from motor vehicle air 
conditioners but does not purify it. That standard will be
finalized, 
upon completion of the public comment period, in a separate 
rulemaking.
   Under the proposal, an EPA approved "independent standards 
testing organization" would certify that equipment met the
applicable 
standards. Upon such certification, the equipment would meet 
EPA's definition of approved refrigerant recycling equipment. 
The September proposal outlined the procedures for EPA approval 
of independent standards testing organizations. These approved 
organizations would test equipment and certify that equipment 
met the applicable standards. EPA proposed standards for the 
proper use of approved equipment, as well as a procedure for 
EPA determination of whether equipment was "substantially
identical" 
to approved equipment.{1}
      ³{1} Substantially identical equipment purchased on or 
      ³before the date of EPA's proposal would be deemed to 
      ³be approved equipment.
   In addition to using approved equipment, service or repair 
technicians would have to be trained and certified by an approved 
technician training and certification program. The proposal 
described the standards for approval of such programs, as well 
as application procedures.
   The January 1, 1992 effective date would be delayed for one 
year for small volume shops-entities that serviced less than 
100 motor vehicle air conditioners during 1990. This one year 
delay would apply only for those small entities that filed a 
small entity certification with EPA on or before January 1, 
1992. In addition, as of November 15, 1992, the sale or
distribution 
of class I or class II substances suitable for use in motor 
vehicle air conditioners was restricted in containers of less 
than 20 pounds of such substances to persons who were properly 
trained and certified under the regulation, or who purchased 
them for resale only.
   The Agency proposed certification and recordkeeping requirements

needed for compliance monitoring. In addition to the statutorily 
required certification to the Administrator of small entity 
status and equipment ownership, the Agency proposed that service 
establishments retain records of service events and amounts 
of refrigerant purchased. The amount of refrigerant sent to 
reclamation facilities would have to be recorded and sellers 
of refrigerant would be required to record technician certification

numbers and amounts sold.
   In developing the proposed rule, the Agency received guidance 
from the Stratospheric Ozone Protection Advisory Council (STOPAC) 
subcommittee for Servicing of Motor Vehicle Air Conditioning. 
This subcommittee was made up of members of the original STOPAC 
that advised the Agency on the development of the production 
phase-out requirements and the international negotiations, as 
well as additional representatives from the automobile industry, 
environmental groups, and State and local government. Several 
members of the voluntary program described in section I.F. also 
participated. The Agency wishes to acknowledge their valuable 
assistance in the development of the proposal.

II. Summary of Public Participation

   A public hearing on the proposed rule was held on September 
13, 1991. Six groups presented oral comments on the proposed 
requirements and submitted written testimony to the Agency. 
A transcript of the hearing is contained in the public docket.
   The agency received a total of 68 letters on the proposed 
rule. The technician certification standards were frequently 
addressed. Commenters requested clarification of the term
"independent 
testing authority". Many commenters addressed the effectiveness 
and validity of a minimum standard that allowed unproctored 
testing. Several commenters requested the option of developing 
their own training and certification programs. Commenters also 
frequently addressed the definition and use of approved equipment. 
In general, there was significant support for the Agency's option 
of allowing both recover only and recover/recycle equipment, 
although several comments expressed serious concern over misuse 
of equipment and refrigerant contamination.
   Several commenters requested clarification of the recordkeeping 
requirements for their specific circumstances. Commenters also 
addressed the relationship between state and federal regulatory 
requirements. Many expressed concern about the continued sale 
of small containers of class I and class II substances and possible

adverse consequences if alternative refrigerants are used in 
equipment. Other issues addressed in the comments included the 
substantially identical equipment determination and equipment 
testing and labeling.

III. Responses to Major Public Comments

   A document summarizing the public comments to this rulemaking 
is available in the public docket for this final rule. The major 
issues raised by the commenters and the Agency's responses to 
them are described below. Other comments are addressed in the 
comment response document also found in the public docket.

A. Definitions


1. Motor Vehicle Air Conditioners

   Several commenters addressed EPA's proposed definitions of 
"motor vehicle" and "motor vehicle air conditioner." As proposed, 
motor vehicle would be defined as "any vehicle which is self-
propelled and designed for transporting persons or property, 
including but not limited to passenger cars, light duty vehicles, 
heavy duty vehicles, farm vehicles and construction equipment." 
The definition of motor vehicle air conditioner was proposed 
as a "mechanical compression refrigeration equipment used to 
cool the driver's or passenger's compartment of any motor vehicle. 
This definition is not intended to encompass the hermetically 
sealed refrigeration systems used on vehicles for refrigerated 
cargo." While the hermetically sealed refrigeration system that 
cools the storage container of a refrigerated transport truck 
would be excluded, the unit that cools the driver or passenger 
compartment of such a truck would be included.
   As proposed a broad array of vehicles would be defined as 
a motor vehicle for purposes of regulation under section 609 
of the Act. Coverage would extend beyond the definition of motor 
vehicle used for purposes of title II, part A of the Act, and 
should include a wide variety of off-road equipment, trains, 
and mining equipment. In the notice of proposed rulemaking, 
EPA noted that the passenger air conditioner units for these 
vehicles use CFC-12 as the refrigerant, with the possibility 
that future refrigerants such as HFC-134a would be used. EPA 
was concerned about the breadth of coverage in the proposed 
definition of motor vehicle, and therefore specifically requested 
comment on inclusion of off-road vehicles in the definition 
of motor vehicle.
   Several commenters discussed this issue, and in general
counseled 
caution in extending the section 609 regulations beyond the 
scope of vehicles defined as a motor vehicle for the purposes 
of title II of the Act. They argued that the proposed definition 
of motor vehicle was too broad, and should not include farm 
and construction equipment. They viewed the definition of motor 
vehicle in title II as controlling. In the alternative, they 
suggested EPA conduct a study of the contribution of CFC's from 
air conditioner servicing for such off-road vehicles, and the 
potential regulatory burdens of extending section 609 to them, 
before including such vehicles in the section 609 program. The 
commenters argued that the flexibility was needed, given the 
unique circumstances of off-road equipment dealers, the fact 
that repair and maintenance of off-road vehicles is often performed

in the field, and the seasonal and sporadic demand for air
conditioner 
repairs for these vehicles. At the same time, other commenters 
argued that EPA should include off-road equipment, aircraft, 
and marine vessels in its definition of motor vehicle, to provide 
broad coverage under section 609 regulations.
   EPA has decided to limit the definition of motor vehicle 
for purposes of section 609 to include only those vehicles that 
meet the definition of motor vehicle under section 216(2) of 
the Act. While EPA does not believe that section 609 precludes 
a broader definition,{2} the Agency believes the best exercise 
of its discretion is to exclude off-road vehicles from the
definition 
of motor vehicle at this time, given the significantly different 
circumstances presented by off-road vehicles.
      ³{2} EPA is not persuaded by commenters' arguments that 
      ³Section 609 is limited by law to motor vehicles as
defined 
      ³in section 216(2). First, the definition of motor
vehicle 
      ³found in Section 216(2) of the Act is explicitly
limited 
      ³in application to part A of title II. In addition,
neither 
      ³the statute nor the legislative history for Section 609

      ³indicates that motor vehicle as used in that section 
      ³is limited by law to those vehicles included in the
title 
      ³II part A definition. 
   EPA expects that implementation of the section 609 regulations 
adopted today will occur in a smooth and straightforward manner 
for on-road vehicles; the industry has been involved in a voluntary

recycling effort for several years, and there is a general
uniformity 
in the type of vehicle and air conditioner covered by the
definition, 
as well as uniformity in service and repair circumstances. Off-
road vehicles, however, present a different picture. These vehicles

differ widely in nature, reflecting the broad array of industries 
in which they are used. Some are mobile but many are not,
potentially 
leading to a wide variety of service and repair circumstances. 
Certain of these industries have been involved with the voluntary 
recycling program, but as a whole they have not been closely 
involved as the traditional motor vehicle sector.
   As noted by the commenters, these differences pose a wide 
variety of potential problems, ranging from access to reclamation 
centers to difficulties in air conditioner servicing. EPA therefore

believes it is appropriate at this time to confine the definition 
of motor vehicle for purposes of section 609 to on-road
vehicles.{3} 
These vehicles encompass the overwhelming majority of vehicle 
air conditioners, and constitute the core group Congress meant 
to cover under section 609.
      ³{3} To avoid confusion, vehicles that otherwise meet 
      ³the definition of motor vehicle are covered by these 
      ³regulations notwithstanding their use, for example, on 
      ³farms or construction sites.
   At the same time, EPA is aware that voluntary recycling is 
expanding in certain segments of the off-road sector, and supports 
such efforts. EPA will consider these off-road vehicles under 
the section 608 program, which extends to all uses of class 
I and II substances as refrigerants. For all of these reasons, 
EPA therefore believes that the definition of motor vehicle 
being promulgated as part of these regulations should have no 
adverse environmental effects.
   The Agency would also like to clarify that the HCFC-22 air 
conditioner systems typically found in buses are not included 
in the definition of motor vehicle air conditioner at this time, 
because these systems are more akin to stationary units in their 
functioning and the type of refrigerant they use. In addition, 
the SAE standards referenced in the Act and the certified recycling

equipment developed under those standards is not appropriate 
for use with HCFC-22 systems. EPA expects that such HCFC-22 
air conditioning systems will be subject to the venting prohibition

in section 608 of the Act and that the servicing of these systems 
will be covered by the regulations implementing section 608.
   Finally, the Agency wishes to respond to comments from the 
Motor Vehicle Manufacturing Association (MVMA), Navistar, and 
the John Deere Company that questioned whether the charging 
and/or repair of motor vehicle air conditioners, prior to
completion 
of final assembly of the vehicle, should be covered by this 
regulation. In additional comments received after the close 
of the comment period, MVMA highlighted that the type of equipment 
currently used in the manufacturing facility to recover refrigerant

during repairs is "specialized production equipment singularly 
intended for high volume operation in delivering clean refrigerant 
to every unit, every time. Such large volume equipment is designed 
to be a permanent, stationary fixture in the plant * * *". The 
comments state further that "[i]ndustry equipment used during 
the manufacturing process clearly meets the substantive
requirements 
of the proposed regulation even though, because of its in-line 
nature, Underwriter's Laboratory (UL) or other certification 
does not exist and is not appropriate." This type of equipment 
was contrasted to the small, low volume, moveable equipment 
found in the service sector. EPA believes the repair of newly 
manufactured units is not likely to be a common occurrence and 
when it does occur, the manufacturing facilities clearly use 
equipment to recover and recycle the refrigerant so that it 
may be reintroduced once the motor vehicle air conditioner is 
repaired. The equipment is significantly different from the 
kind of equipment covered by EPA's definition of approved
equipment, 
yet serves the purpose of such equipment equally well. In addition,

the technicians performing this operation are typically
manufacturing 
employees, not service technicians. For all these reasons, the 
Agency believes it is not necessary at this time to extend the 
requirements of this servicing regulation into the assembly 
operation.
   MVMA did note that the manufacturer's garages perform air 
conditioner service and repair activities on company-owned fleet 
vehicles that is akin to the service and repair performed by 
dealerships. EPA agrees with MVMA that such repair and service 
activities should be and are fully covered by today's regulation. 
EPA wants to be clear that this exclusion is limited to final 
assembly activities conducted by the vehicle's original
manufacturer, 
and does not include service or repair activities conducted, 
for example, by a dealer.

2. Refrigerant

   This term is defined to mean any class I or class II substance 
used in a motor vehicle air conditioner and, effective November 
15, 1995 (five years after enactment of the Act), any substitute 
substance, such as HFC-134a. For clarity, this additional provision

of section 609(b)(1) was added to the definition.
   The Agency emphasizes that any blend of substance that includes 
a class I or class II substances, such as R-176 (a blend of 
CFC-12, HCFC-142b and HCFC-22), is included under today's
requirements 
and must be recovered or recycled at service. EPA also is
evaluating 
the impact of alternative refrigerants, including R-176, on 
the effectiveness of its recycling efforts.

3. Service Involving Refrigerant

   The Agency stated in the proposal that the intent of the 
Act is to require recycling of refrigerant in motor vehicle 
air conditioners whenever service is being performed that may 
release refrigerant to the atmosphere. This includes service 
of motor vehicle air conditioners and service of other motor 
vehicle components that may require some dismantling of the 
motor vehicle air conditioning system. Servicing of motor vehicle 
air conditioners, therefore, includes repairs, leak testing, 
and "topping off" of air conditioning systems low on refrigerant, 
as well as any other repair which requires some dismantling 
of the air conditioner. Each of these operations involves a 
reasonable risk of releasing refrigerant to the atmosphere.
   Four commenters stated that if recovery of refrigerant at 
disposal is not required under section 609, it should be covered 
by the safe disposal program under section 608. As stated in 
the proposal, EPA would like to encourage recovery of refrigerant 
at disposal. The specific requirements for recovery at disposal, 
it any, may be addressed in the regulations implementing the 
safe disposal program under section 608 of the Act. The Agency 
will consider the commenters' suggestions on this issue when 
addressing the safe disposal requirements under section 608.

4. Service For Consideration

   In the proposed rule, the Agency interpreted "service for 
consideration" to include persons who are paid to perform service 
on motor vehicle air conditioners, thus subjecting to regulation 
all service except that done for free. Several commenters
questioned 
whether fleets are included. The Agency would like to clarify 
that fleets of vehicles, whether private, or federal, state 
or local government owned, are covered because the technicians 
doing the service are being paid. Other examples of establishments 
doing service covered by the regulations include, not are not 
limited to, independent repair shops, service stations, fleet 
shops, body shops, chain or franchised repair shops, new or 
used car and truck dealers, rental establishments, radiator 
repair shops, mobile repair operations, vocational technical 
schools (because instructors are paid), farm equipment dealerships,

and fleets of vehicles at airports.
   Two commenters suggested adding the recover, recycle, reclaim 
definitions to the rule language with the definition of service. 
The Agency did not propose this and will not be incorporating 
the definitions formally into rule language now. The meaning 
of these words may evolve over time with continued technological 
innovation. The Agency does not wish to impede this progress 
through inclusion of a definition of these terms in the
regulations.
   Comments from MVMA, Navistar, and the John Deere Company 
questioned whether the charging and/or repair prior to the
completion 
of final assembly is covered under the "service for consideration" 
definition. As previously discussed in section III.A.1., a motor 
vehicle air conditioner is not subject to these regulations 
prior to the completion of final assembly of the vehicle by 
the original equipment manufacturer. While repair or service 
work on air conditioners in unfinished vehicles may well fit 
the definition of "service for consideration," the equipment 
and technician certification requirements of these rules do 
not apply as the motor vehicle air conditioner is not subject 
to these rules prior to completion of the final assembly process 
by the vehicle's manufacturer.

5. Properly Using

   The Act requires that the Administrator establish standards 
for using equipment that shall be at least as stringent as the 
applicable standards of the Society of Automotive Engineers 
(SAE) in effect as of the date of enactment (November 15, 1990). 
The standard referred to, J1989, provides recommended service 
procedures for the containment of CFC-12. In the September 4, 
1991 notice, the Agency proposed that the standard for "properly 
using" include J1989 and an additional requirement that if recover 
only equipment is used, the refrigerant must be sent off-site 
for reclamation or recycled on-site. The Agency also proposed 
that, as prescribed in the SAE J Standards, refrigerant received 
from an off-site reclamation facility that is intended for recharge

of automobiles must been the Air-conditioning and Refrigeration 
Institute standard of purity (ARI Standard 700-88) for CFC-12.
   The proposed definition of properly using was intended to 
apply to facilities that own an on-site recycle machine or an 
on-site recycle machine and several recover only machines (such 
as large establishments with many service bays) as well as small 
facilities that purchase one piece of recover only equipment. 
The Agency believes that the requirement that such equipment 
be properly used will ensure that recovered refrigerant is not 
vented to the atmosphere. The Agency wishes to highlight that 
under the properly using definition, refrigerant introduced 
into the system for the purpose of leak detection must be recovered

and not vented.
   Three commenters supported EPA's proposed properly using 
standard, stating that if EPA allowed recover only equipment 
to be used, the Agency should require that recovered refrigerant 
be either recycled on-site or sent off-site for reclamation 
as a means of minimizing prospects of contamination of motor 
vehicle air conditioners. These commenters suggested that the 
Agency consider methods to assure that the reclamation facilities 
have the capability to reclaim refrigerant to the ARI 700-88 
standard. EPA does intend to consider requirements for reclamation 
facilities in the section 608 regulation under the Act.
   Several commenters questioned whether several service
establishments 
owned by a single owner may recover refrigerant and send the 
refrigerant to a central location for recycling to the SAE J1991 
standard for CFC-12. The Agency believes that this practice 
may be a cost effective option in some situations. To minimize 
the risk of contamination (whether intentional or unintentional), 
this option will only be available when the owner of the recover 
only equipment is also the owner of the recover/recycle equipment 
and is therefore able to assure direct recycling of refrigerant 
from motor vehicles for use in motor vehicles serviced at his 
facilities. The equipment used to recycle the refrigerant must 
meet the standards for CFC-12 recycle machines adopted in appendix 
A.{4} Franchised or chain service establishments (i.e. those 
service establishments that share a common name but are separately 
owned) may not use this option.
      ³{4} The equipment standards in Appendix A are designed 
      ³for equipment that recovers and recycles CFC-12
refrigerant. 
      ³As necessary, EPA will adopt additional standards that 
      ³will govern the approval of equipment designed to
recover/recycle 
      ³other refrigerants.
   This is the only exception to the on-site requirement for 
recycling. In all other cases, if refrigerant leaves the service 
establishment then it must be reclaimed to the ARI 700-88 standard 
to assure purity. The on-site requirement is important because 
equipment certified to meet the SAE standards is only capable 
of cleaning CFC-12 to the SAE J1991 standard if that refrigerant 
has been removed from a motor vehicle; refrigerant from another 
type of air conditioning or refrigeration system may contain 
contaminants, such as acid formed in a compressor burn-out, 
that such equipment is not designed to remove. Introduction 
of this contaminated CFC-12 could result in severe damage to 
the motor vehicle air conditioner. This type of damage would 
destroy consumer confidence in recycled refrigerant and jeopardize 
the success of the recycling program.

B. Equipment Certification


1. Approved Equipment

   In the September 4, 1991 Notice of Proposed Rulemaking, the 
Agency proposed defining the statutory term "approved refrigerant 
recycling equipment" to include two types of equipment. One 
type, recover/recycle equipment, both extracts refrigerant from 
the motor vehicle air conditioner and cleans the refrigerant 
on-site. The other type of equipment, recover only, extracts 
the refrigerant from the motor vehicle but does not clean the 
refrigerant. The refrigerant from these recover machines must 
be sent off-site for reclamation or recycled on-site. The Agency 
proposed this definition to provide flexibility to the regulated 
community and to maximize environmental protection while protecting

air conditioning units from damage. The September 4, 1991 notice 
proposed Appendix A as the standards to which recover/recycle 
equipment would have to be certified. The supplemental notice 
published on April 22, 1992 proposed the standard for recover 
equipment as Appendix B.
   The terms "extraction", "reclamation" and "recycle" are terms 
of art currently used by the industry, and refer to the removal 
of refrigerant (extraction), processing of the refrigerant off-
site to a near virgin condition of purity (reclamation), or 
processing of the refrigerant on-site to a condition acceptable 
for reuse as a refrigerant in the same vehicle, without the 
need to send it off-site for reclamation (recycle).{5} The ANPRM 
published May 1, 1990 and the NPRM published September 4, 1991 
defined these terms.
      ³{5} Industry has adopted separate voluntary standards 
      ³for the purity of refrigerant, depending whether it is 
      ³sent off-site for reclamation (ARI 700-88) or is
recycled 
      ³on-site (SAE J1991).
   Seen against this background, the section 609 definition 
of "approved refrigerant recycling equipment"{6} is an ambiguous 
term, leaving EPA with the obligation to establish its meaning 
in a way that best effectuates the goals of this section. First, 
the statutory definition of "refrigerant recycling equipment" 
refers to equipment that "extracts and reclaims". The recycle 
equipment normally used in this context however is equipment 
that cleans the refrigerant on-site, but does not reclaim it. 
The latter term is reserved for refrigerant that is sent off-
site for distillation to a higher standard of purity. At the 
same time, section 609(b)(2) references SAE J1990, which states 
that its purpose is to "provide equipment specifications for 
* * * recycling and/or recovery, and recharging systems."{7}
      ³{6} Section 609 defines the term as "equipment
certified 
      ³by the Administrator * * * to meet the standards
established 
      ³by the Administrator and applicable to equipment for 
      ³the extraction and reclamation of [motor vehicle air 
      ³conditioner] refrigerant * * *". The standards that EPA

      ³sets are to be as stringent as one set by the Society 
      ³of Automotive Engineers, SAE J1990.
      ³{7} See section 1. "Scope", SAE Standard J1990.
   The legislative history fails to resolve this ambiguity in 
the statute. However, it does appear clear from the terms and 
structure of section 609 that Congress focused on activities 
conducted at the service establishment, whether recovery or 
recovery/recycle, and was not legislating specification for 
off-site equipment used to reprocess refrigerant to near virgin 
purity.
   EPA, therefore, attempted to define "approved refrigerant 
recycling equipment" with the view of providing environmental 
protection, and providing the affected industry flexibility 
to meet the changing nature of refrigerants. For all the reasons 
described in the September 4, 1991 Notice, EPA proposed a
definition 
including both types of equipment.
   The comments submitted on this issue focused primarily on 
the feasibility and practicality of the proposed definition, 
and not on EPA's authority to include recover only equipment. 
One commenter, however, argued that SAE standard J1990 set the 
minimum requirements for "approved refrigerant recycling
equipment." 
Since section 3.1 of this SAE standard established that the 
equipment must be able to extract and process refrigerant, recover 
only equipment could not meet the minimum requirements as stringent

as J1990, and, therefore, could not be approved. Congress, by 
incorporating SAE J1990 in section 609, intended that EPA adopt 
the then existing automotive recycle program, which did not 
extend to recover only equipment. The commenter did seem to 
accept that EPA could approve recover only equipment in the 
future if such equipment was found to be necessary, for example 
with respect to future refrigerant blends.
   The commenter's arguments do not persuade EPA that it lacks 
authority to interpret refrigerant recycling equipment as including

recover only equipment. First, the portion of SAE J1990 noted 
above and quoted in the comments does no more than highlight 
an apparent inconsistency in that document. It does not remove 
the ambiguity present in this statutory term, and does not indicate

a clear Congressional intent to exclude recover only equipment 
from approval under Section 609. In addition, the Agency's
restrictions 
on the use of recover only equipment{8} tie it closely to the 
extraction, recycling or reclamation process. Finally, for the 
reasons discussed below, EPA believes that it is reasonable 
to interpret "approved refrigerant recycling equipment" to include 
recover only equipment.
      ³{8} For example, any recovered refrigerant must be
recycled 
      ³on-site or sent off-site for reclamation except for the

      ³limited situations described in III.A.5.
   As noted earlier, the majority of commenters focused not 
on the legal issue of statutory interpretation, but on the proper 
policy for EPA to follow; in effect, not whether it could approve 
such equipment, but whether it should do so. Seventeen commenters 
supported allowing both certified recover/recycle equipment 
and recover only equipment to meet the definition of approved 
equipment. The commenters cited the importance of allowing service 
establishments the flexibility to chose equipment that suits 
their individual circumstances. Commenters believed that this 
would increase compliance with the requirements. Many commenters 
noted that recover only equipment has a lower initial cost than 
recover/recycle equipment and that many service establishments 
are already using this type of equipment. This equipment is 
also used in conjunction with recover/recycle equipment, for 
example in service establishments with several service bays. 
Commenters stated that the lower initial cost will become
increasingly 
important in the future when different refrigerants (e.g. HFC-
134a, blends) enter the motor vehicle servicing market. Commenters 
mentioned the importance of recover equipment for the salvaging 
of refrigerant from disposed automobiles (requirements that 
will be covered under section 608 of the Act) and that refrigerant 
sent off site for reclamation is actually purified to a higher 
standard than refrigerant recycled on-site. Commeters disputed 
claims that the use of recover only equipment would lead to 
an increased risk of venting refrigerant or contamination through 
the reuse of unrecycled refrigerant.
   The Agency received five comments opposed to recover only 
equipment in the motor vehicle servicing sector. MVMA opposed 
recover equipment for several reasons. MVMA stated that approval 
of recover only equipment does not reflect Congressional intent 
or the intent of the automobile industry when they developed 
the voluntary program for CFC recycling. The Association suggested 
that recover only equipment would lead to venting of refrigerant. 
It would jeopardize the purity of refrigerant in the motor vehicle 
sector because of the economic incentives derived from the greater 
economic value of refrigerant ready for use in a car as compared 
to refrigerant sold for reclamation. MVMA also stated that the 
use of recover only equipment is not cost effective, whereas 
recover/recycle equipment is cost effective and more easily 
implemented. MVMA argued that the potential need for recovery 
of other refrigerant in the motor vehicle sector did not justify 
the use of recover only machines. Other commenters emphasized 
the need to require off-site reclamation if recover only equipment 
were allowed, and mentioned that the limited number of reclamation 
centers across the country could render the recover only option 
unworkable.
   The Agency understands that the voluntary recycling program, 
which it supported, and the SAE standards were intended to
establish 
and promote on-site recycling, and agrees that on-site recycling 
may well be an efficient option for most service entities because 
of the efficiency of the procedure. However, the Agency believes 
that approving two separate standards for equipment provides 
both environmental protection and needed flexibility to the 
regulated community. As stated in the proposal, the cost
effectiveness 
of equipment is dependent on the number of service jobs performed 
and the price of virgin refrigerant. Some service establishments 
may find it more cost effective to comply with the regulations 
by purchasing recover only equipment.
   As stated in the September 4, 1991 notice and the April 22, 
1992 supplemental notice, the Agency examined the relative
environmental 
consequences of using the two types of equipment. For example, 
the efficiency of removal of refrigerant is equivalent between 
the two types of equipment and both types of equipment separate 
the lubricant from refrigerant to indicate the amount of lubricant 
that must be returned to the system. Unlike recycling equipment, 
recover only equipment does not purge non-condensable gases 
during operation. Such purging in recover/recycle equipment 
may result in the loss of 5 percent of refrigerant in a purge. 
Recover only equipment therefore provides at least as much
protection 
from the release of refrigerant as recover/recycle equipment.
   Flexibility is also an important consideration for the potential

need to recover other refrigerants in the motor vehicle sector 
in the future. Several automobile manufacturers have announced 
that HFC-134a is the designated replacement for motor vehicle 
air conditioners in new cars beginning as early as 1992 in some 
models. This substitute must be recycled under the Act, effective 
November 15, 1995. For retrofit of existing CFC-12 systems, 
research is currently underway to determine an appropriate
substance 
and both HFC-134a and HCFC blends are being considered. Under 
the Act, blends containing HCFCs are subject to this regulation 
if they are used in motor vehicle air conditioners and recover 
only equipment approved for use with blends may be an attractive 
option in this case. The Agency does not wish, as a result of 
delays associated with the regulatory process, to impede the 
progress of the sector as it addresses the challenges of
alternative 
refrigerants in the future.
   The Agency is very concerned about the issue of contamination 
of refrigerant raised by MVMA's comments but believes that the 
option of two types of equipment will not increase the risk 
of contamination or venting. On the issue of contamination, 
the Agency notes that regardless of how the refrigerant is
extracted, 
today's rule requires that it be purified to standards that 
allow its safe use in motor vehicle air conditioners before 
it is so used. Refrigerant recycled on-site must be cleaned 
to the SAE J1991 standard of purity for recycled refrigerant. 
Any refrigerant that leaves the site must be reclaimed to the 
ARI-700 standard of purity, a standard developed by the Air-
conditioning and Refrigeration Institute that defines the level 
of quality for reclaimed refrigerants. The only exception to 
this is described in section III.A.5. under the definition of 
"properly using." Moreover, recharging motor vehicle air
conditioners 
with used refrigerant that has not been purified in accordance 
with the applicable standard is prohibited.
   The proposed standard for recover only equipment would make 
it highly unlikely that refrigerant extracted using recover 
only equipment would be reused in recharging motor vehicle air 
conditioners before being purified. That standard would require 
that "[t]he equipment discharge or transfer fitting shall be 
unique to prevent the unintentional use of extracted CFC-12 
to be used for recharging auto air conditioners." In other words, 
recover only equipment would have to be designed so that it 
can be connected, for example, to a recover/recycle machine 
for recycling of extracted refrigerant, but could only be directly 
connected to the recharging equipment under circumstances of 
intentional tampering. It would therefore be extremely difficult 
for recover only machines to be misused in the way MVMA fears. 
In addition, it is unlikely that persons in the business to 
service motor vehicle air conditioners would knowingly use
contaminated 
refrigerant since they have an interest in satisfying customers 
and not injuring the customer's air conditioner.
   As for venting, EPA believes that there is little chance 
that use of recover only machines would lead to venting. First, 
such venting is prohibited by these regulations for both recover 
only and recover/recycle equipment. Second, recover only equipment 
users would have an economic incentive not to vent but to either 
recycle or reclaim the extracted refrigerant. Since unpurified 
extracted refrigerant may not be used to recharge motor vehicle 
air conditioners, recover only equipment users can be expected 
to either recycle the extracted refrigerant before recharging 
the air conditioner, or to sell it to reclaimers. Finally, any 
risk of venting or contamination from the use of recover only 
equipment should be minimized by the required technician training 
and certification, which will alert technicians to the proper 
procedures to be followed.
   Several commenters questioned whether one owner with several 
service establishments using recover only equipment could ship 
refrigerant to a central location for recycling, as opposed 
to reclamation where the same owner owns the recover only equipment

and the recycling equipment. As discussed under the definition 
of "properly using" (section III.A.5), the Agency believes that 
this practice may be a cost effective option in some situations. 
The Agency wishes to clarify that because of the importance 
of protecting refrigerant and the inability to assure the source 
of the refrigerant once it leaves the service site, this is 
the only exception that can be made from the on-site recycling 
requirement. A company may also wish to set up a central
reclamation 
facility if it wishes to assure the purity of refrigerant.
   EPA shares the concern of commenters regarding the limited 
number of reclamation facilities in the country. Any service 
establishment considering the purchase of recover only equipment 
should first determine if refrigerant reclamation opportunities 
exist in their area and the cost of using such service. The 
Agency would like to encourage the development of reclamation 
operations with the capability to clean refrigerant to the ARI-
700 standard. It is of utmost importance to the proper functioning 
of air conditioning equipment that all refrigerant sold by
reclaimers 
meets the ARI-700 standard of purity. Therefore, the Agency 
will consider a reclaimer certification program under its section 
608 requirements. In developing the requirements, the Agency 
will consider the commenters' concern for periodic inspections 
of refrigerant quality and any possible measures to facilitate 
the development of the reclamation network around the country.
   SAE commented that the 1989 version of SAE standard J1990 
has been revised by SAE to add clarity and specification. Changes 
include the following:
   (1) Section 1 of J1990 was revised to clarify that the scope 
of the standard applies to recover/recycle equipment, and not 
to recover only equipment (this is consistent with the SAE draft 
standard J2209 which applies to recover only equipment);
   (2) Section 3 of J1990 added a labeling requirement, referring 
to the standard;
   (3) Section 4 of J1990 is more specific regarding purge devices 
required for non-condensable gases (NCG). The equipment must 
either have an automatic purge device to expel NCG, or have 
a device that warns the operator if the limit for NCG has been 
received. In addition, a limit was placed on the refrigerant 
loss from the purging of NCG; the limit was set at 5% by weight 
of the total refrigerant recovered;
   (4) Section 7 of J1990 clarified the requirement in the 1989 
version that the equipment reduce the system to a vacuum. Revised 
J1990 requires that the equipment reduce system pressure to 
a minimum mercury level (4 in./102 mm) below atmospheric pressure; 
and
   (5) Section 7 of J1990 also clarified the section regarding 
the extraction of used lubricants, for example discussing the 
need to only use new lubricant to replace the amount removed. 
The equipment must take into account the amount of refrigerant 
dissolved in the lubricant to avoid indicating the recovery 
of more lubricant than actually removed. 
   EPA agrees that the final standard for recover/recycle equipment

should include these revisions to J1990 because the Agency believes

these changes are minor in nature, and are not a significant 
change to the 1989 version of J1990 that EPA proposed in the 
NPRM. For example, section 4 of J1990 (1989) required a device 
to alert the operator that the NCG level had been exceeded, 
if the equipment had a self-contained recovery tank. The 1991 
version expands on this concept. With respect to the amount 
of refrigerant loss attributable to purge of NCG, EPA noted 
in the NPRM that UL estimated that CFC-12 releases were well 
under 5% in machines certified prior to that date. With respect 
to the specification of a vacuum level, the change clarifies 
an ambiguous term in the old standard but does not change the 
level of extraction efficiency. The same can be said for the 
changes regarding lubricant extraction.
   While including the changes to J1990 in the standard for 
recover/recycle equipment, EPA will only apply this revised 
J1990 standard to recover/recycle equipment certified after 
February 1, 1992. The standard for equipment certified prior 
to that date shall be J1990 (1989), the version proposed in 
the NPRM. EPA is taking this action for several reasons. First, 
a large number of recover/recycle machines have already been 
purchased, with the overwhelming majority of them certified 
to J1990 (1989). It would impose a significant economic burden 
to require equipment owners to either recertify their equipment 
or purchase new equipment. Second, as discussed above, the changes 
made to the 1989 version of J1990 are minor in nature and do 
not reflect any significant increase in environmental protection. 
Third, the 1989 version of J1990 clearly meets the statutory 
requirement of Section 609(b)(2)(A)-that section of the Act 
refer, in fact, to the 1989 version of J1990 as the minimum 
standard for equipment. Fourth, February 1, 1992 is a reasonable 
date to use as Underwriters Laboratory started using revised 
J1990 for all equipment submitted for certification after that 
date. 
   Three commenters objected to the statement in the September 
4, 1991 notice regarding the appropriate method to handle the 
lubricant removed from refrigerant by either recover/recycle 
or recover only equipment. In the proposal, the Agency stated 
that the lubricant should be handled in the same manner that 
the service establishment handles used oil. Since the publication 
of the September 4 notice, the Office of Solid Waste and Emergency 
Response published a Supplemental Notice of Proposed Rulemaking 
on used oil characterization and management standards (56 FR 
48000, September 23, 1991). The Agency would like to clarify 
that the presence of CFCs in used lubricant may have implications 
for how the used lubricant should be handled. The Agency refers 
persons to that rulemaking for further information on this issue. 

2. Substantially Identical Equipment 

   The Act states that equipment purchased before the proposal 
of regulations under this section shall be considered certified 
if it is "substantially identical" to approved equipment. In 
the NPRM, the Agency proposed a process for review of uncertified 
equipment that would rely primarily on the manufacturer submitting 
information, such as process flowsheets, lists of component, 
or laboratory tests, to the Agency for review. Owners of equipment 
may also submit information to the Agency if they are unable 
to establish the status of equipment through the manufacturer. 
The Agency stated that it would narrowly interpret the
substantially 
identical clause in order to protect the air-conditioning units 
and the integrity of the recycling program. 
   Several commenters agreed that EPA should maintain a strict 
interpretation of the substantially identical clause while others 
stated that EPA should recognize industry efforts by not declaring 
equipment purchased and used in good faith to be obsolete. In 
response to the latter group of comments, EPA points out that 
Congress' clear intent in providing an exception for substantially 
identical equipment was to credit industry efforts undertaken 
before the development of regulations to the greatest extent 
possible without endangering the environment and air conditioning 
equipment. 
   The Agency would like to clarify that recover/recycle equipment 
that has been design certified by Underwriters Laboratory{9} 
as meeting the SAE standards in appendix A is considered approved 
equipment for the purposes of this regulation. The first
recover/recycle 
equipment was certified in September, 1989. Such equipment should 
be labeled with UL's "design certified to meet SAE Standards" 
sticker. This should not be confused with other UL listing stickers

that indicate satisfactory performance in safety testing only. 
The Agency understands that the vast majority of recover/recycle 
equipment sold has been design certified by UL, and EPA maintains 
a list of the certified models. The list is available to the 
public upon request to the address that appears in section 82.36.
      ³{9} EPA discusses its approval of Underwriters
Laboratory 
      ³(UL) under 40 CFR 82.36 as an "independent standards 
      ³testing organization" in section III.C.
   The Agency would also like to clarify that it can only review 
equipment to determine if it is substantially identical to
certified 
equipment once applications for review have been received. One 
commenter's suggestion that the Agency inventory and review 
every model of equipment ever sold is resource intensive and 
impractical. The Agency encourages equipment manufacturers that 
have models that do not have UL certification to submit
applications 
for equipment they believe to be substantially identical to 
certified models. This includes retrofit packages that the
manufacturer 
believes will result in equipment performance to certified levels. 
The Agency's review will concentrate on the aspects of equipment 
that vary from certified models. As stated in the proposal, 
an essential element of such review is that recover/recycle 
equipment purify refrigerant to the SAE J1991 standard of purity. 
For recover only equipment, essential elements of review are 
that equipment remove refrigerant as efficiently as approved 
equipment under the SAE J2209 standard and also that equipment 
separate lubricant. 
   The Agency realizes that the statutory deadlines require 
quick review of the information submitted. As soon as
determinations 
are made, equipment determined to be substantially identical 
will be placed on the approved equipment list as "approved if 
purchased before September 4, 1991" for recover/recycle equipment 
and "approved if purchased before April 22, 1992 for recover 
only equipment. While equipment that EPA has not reviewed may 
in fact be substantially identical, an EPA determination on 
this point is important so a regulated party may verify their 
compliance in advance. 

C. Independent Standards Testing Organizations


1. Summary and Response to Comments

   In the proposal, EPA stated that organizations interested 
in obtaining approval as independent standards testing
organizations 
must apply to the Agency and demonstrate that they are capable 
of performing equipment testing to the applicable standards. 
One commenter stressed the importance of highly trained, qualified 
staff. In addition, commenters argued that the standards testing 
organization should not be owned or controlled by manufacturers 
or vendors of the product being tested, to promote objectivity 
and preclude conflicts of interest. In general, various commenters 
considered the criteria proposed in section 82.38(b)(1)-(5) lacking

in detail and substance.
   EPA agrees that staff expertise is very important, as are 
objectivity and lack of conflicts of interest. However EPA believes

these factors are fully addressed in the proposed regulations. 
For example, the proposal required that the applicant must
demonstrate 
"[e]xpertise in equipment testing and the technical experience 
of the organization's personnel." In addition, the organization 
could have no conflict of interest and receive no financial 
benefit from the outcome of certification testing."{10} These 
criteria provide adequate detail and substance for an applicant 
to prepare its submission and guide the agency in its
determinations. 
Evidence supporting this are the detailed and substantive
applications 
that have already been submitted. Accordingly, the Agency is 
adopting the criteria as proposed, excepting changes for purposes 
of clarification.
      ³{10} In response to a comment seeking clarification, 
      ³this condition clearly allows an independent standards 
      ³testing organization to generate a reasonable profit 
      ³margin. However, it would preclude, for example,
charging 
      ³a fee based on the results of a test, as well as
ownership 
      ³of the testing organization by a manufacturer or vendor

      ³of the equipment being certified.
   One commenter urged EPA to make clear that UL 1963 and the 
SAE standards apply only to motor vehicle air conditioning
equipment. 
This commenter correctly points out that there are separate 
industry standards (ARI Standard 740-91) that apply for equipment 
used for recovery and recycling in the other air conditioning 
and refrigeration sectors.
   Equipment that recovers and recycles refrigerant must be 
certified to meet the SAE standards in appendix A. While EPA 
is not promulgating a specific test procedure that each independent

standards testing organizations must follow, EPA does want to 
emphasize that EPA's review of an application of an organization 
for approval under section 82.38 will include a review of the 
test procedure the organization intends to employ. The application 
for approval will need to include information on the proposed 
test procedure and an explanation of its adequacy. Any approval 
of an organization will be contingent on use of such test
procedure. 
While EPA considers this implicit in the criteria proposed in 
the NPRM, EPA is clarifying the final regulation to reflect 
the above.
   EPA notes that the approval of UL, discussed herein, is based 
in part on the testing protocol developed by UL known as UL1963. 
EPA expects that a UL testing protocol will also be developed 
for testing the ability of recover only equipment to comply 
with applicable SAE standards. The Agency anticipates that a 
UL testing procedure will also be developed for this equipment.

2. Approved Independent Standards Testing Organizations

   The Agency received an application for approval for UL on 
October 21, 1991, and from ETL Testing Laboratories, Inc on 
November 27, 1991. The Agency has reviewed their applications 
in detail and has formally approved UL and ETL Testing
Laboratories, 
Inc. as independent standards testing organizations. This approval 
will be effective as of August 13, 1992. EPA encourages
applications 
from other facilities that are capable of testing equipment 
to the necessary standards. The Agency recognizes that since 
a large amount of equipment has already been certified, additional 
laboratories may not find it cost effective to enter the
certification 
market for equipment certified under this section of the Act. 
The EPA will maintain a list of approved independent standards 
testing organizations available upon request at the address 
in section 82.38. As stated in the proposed notice, the Agency
reserves 
the right to revoke approval if the testing organization violates 
any of the requirements contained in section 82.38.

D. Technician Training and Certification

   In the September 4, 1991 notice, EPA proposed standards for 
training and certification in the proper use of approved
refrigerant 
recycling equipment during service of motor vehicle air
conditioners. 
The standards were designed to assure that all aspects of the 
use of approved equipment are covered by certification programs 
while preserving flexibility in testing mechanisms. The Agency 
believes flexibility in testing mechanisms is important in
technician 
certification because of the large number of technicians that 
must be certified in a very short period of time. In addition, 
service technicians are employed in a wide variety of circumstances

and businesses, such that no one program may be adequate for 
all the situations involved.
   Several commenters suggested that EPA had exceeded the intent 
of the statute by proposing a training, test administration 
and certification process, and that uniform Federal certification 
standards are excessive and unworkable. The language and the 
intent of the statute, however, explicitly requires EPA to
establish 
standards for certification and training. In specified
circumstances, 
section 609 of the Act prohibits the service and repair of motor 
vehicle air conditioners except by properly trained and certified 
personnel.{11} Under Section 609(b)(4), EPA is to establish 
the standards for such training and certification, subject to 
a minimum stringency level set by statute. EPA proposed to
accomplish 
this goal by establishing a process to approve technician training 
and certification programs. The proposed criteria for approval 
of such programs balances flexibility of program design with 
an assurance that adequate training would be provided.
      ³{11} The effective date of this prohibition depends on 
      ³the size of establishment and the filing of a proper 
      ³small volume certificate. See the discussion in section

      ³I.H herein.
   Several commenters raised the issue of self-certification, 
especially employer self-certification of employees as in the 
DOT certification for fleet mechanics and drivers. The commenters 
appeared concerned that only a limited number of national training 
and certification programs could seek approval under the proposed 
regulations. In addition, they were concerned that these national 
organizations could not train and certify a large number of 
technicians in a short time.
   The Agency would like to clarify that the two programs mentioned

in the statute, the Mobile Air Conditioning Society (MACS) or 
the National Institute of Automotive Service Excellence (ASE), 
are not the only training and certification programs that can 
seek EPA approval. The Agency did consider these programs, in 
addition to other certification programs and consultation with 
industry, government officials, and environmentalists, in
developing 
the minimum criteria as they appeared in the proposal. Companies 
do have the option of developing their own certification program 
for their technicians; however, the Agency must review these 
programs to assure that they conform to the minimum criteria. 
The intent of the criteria is to establish a framework for
certification 
under which a variety of entities, including testing organizations,

individual companies, fleets and vocational schools, may design 
certification programs.
   The commenters did not provide details on the DOT program 
mentioned. EPA understands it to involve training at the service 
establishment, with the service establishment then maintaining 
records of training. DOT does not review and approve the individual

service establishments' training programs. EPA has serious
questions 
whether such a program meets the minimum requirements set forth 
in section 609(b)(4). In addition, as described above, the review 
and approval process under section 82.40 should provide the 
needed flexibility for a wide variety of organizations, from 
the national, state and local levels, to obtain approval as 
technician training and certification programs.
   The Agency is aware that many technicians may find independent 
testing organizations a simple and cost effective mechanism 
to achieve certification. Also, many companies who train their 
technicians may choose to use an independent testing organization's

program to test or certify their technicians after training. 
The Agency does not wish to discourage any company from developing 
its own training and certification program and will assure parity 
across programs through a review of how each program meets the 
criteria. Agency review is important to assure veracity of
information 
and fairness in testing. For a discussion of the review status 
of the programs developed in advance of this final rule, see 
section D.7.
   The Agency received several specific comments on the various 
criteria proposed for technician certification programs.

1. Training

   EPA proposed that each approved program must provide adequate 
training, using one or more of various formats: On-the-job
training, 
training through self-study of instructional material, or on-
site training involving instructors, videos or a hands-on
demonstration. 
Three commenters suggested that hands-on demonstrations should 
be required in each technician certification program. In developing

the proposal, EPA reviewed the actual operation of recover/recycle 
and recover only equipment and determined that proper operation 
could be adequately described and demonstrated in self-study 
instructional material as well as other kinds of instructional 
material. This is because the skills needed to properly use 
such equipment do not differ substantially from the skills
technicians 
already possess for servicing the motor vehicle air conditioner. 
There is no evidence to suggest that this determination is
inaccurate 
and therefore the Agency will not require hands-on demonstrations 
as a minimum standard. The Agency recognizes that demonstrations 
are valuable and would like to encourage their use whenever 
possible, including manufacturer demonstrations of equipment 
upon purchase. The Agency is aware that some technician
certification 
programs already incorporate demonstrations. The Agency does 
have the authority to revoke a certificate if a technician fails 
to demonstrate for an authorized representative of the
Administrator 
his or her ability to properly use the equipment.

2. Test Subject Material

   EPA proposed that certification tests adequately address 
the relevant SAE J standards established for the service and 
repair of motor vehicle air conditioners, anticipated future 
technological developments (such as the introduction of HFC-
134a), environmental consequences of refrigerant release and 
the adverse effects of stratospheric ozone layer depletion. 
In addition, the certification tests were to cover the general 
regulatory requirements under section 609 to assure that
technicians 
are familiar with the legal requirements regarding service.
   EPA received comments requesting that EPA "grandfather"
technicians 
that were trained and certified before the promulgation of this 
rule. The Agency is aware that thousands of technicians have 
been certified in advance of the effective date of this final 
rule in anticipation of the final requirements and also as part 
of the voluntary program developed several years ago. These 
technicians would not have had the opportunity to receive training 
on the specifics of either section 609 of the Act or of these 
implementing regulations.
   EPA believes it is important that training address the
requirements 
imposed by the Administrator under section 609 of the Act, and 
will require that all training conducted by approved programs 
include such subject material for training conducted after the 
effective date of these regulations. However, training conducted 
before the effective date of these regulations need not include 
the specifics of the final rule. EPA is taking this action for 
several reasons. First, EPA believes that training on the
requirements 
imposed by the Administrator under section 609 of the Act is 
quite valuable, but is not necessary to meet the legal standards 
required under section 609(b)(4). This is shown by the Act's 
reference to the then existing MACs and ASE training programs, 
which could not have included the then future regulatory
requirements 
imposed by EPA in implementing section 609. Second, large numbers 
of technicians have already been trained and certified, and 
it would be a great burden and perhaps impossible to quickly 
retrain and recertify all of these technicians. Third, EPA believes

that many technician training and certification programs did 
include training material on the requirements of section 609 
and EPA's proposed regulations as soon as such information was 
available.
   As stated in the proposal, the technician certification program 
is not intended to test the technical skills of technicians 
regarding the diagnosis and repair of motor vehicle air
conditioners. 
The basic goal of the technician training and certification 
program is to teach technicians how to properly recover and/or 
recycle refrigerant, and why it must be done to protect the 
stratospheric ozone layer.
   The supplemental notice published April 22, 1992, proposed 
an additional equipment standard for motor vehicle air conditioner 
service. Once the standard for recover only equipment is finalized,

technician training and certification programs will have to 
include training and testing on the proper use of such equipment. 
For a further discussion, see section III.D.7.

3. Test Administration

   In the proposed criteria, the Agency did not specify details 
of certification tests such as the number of questions, the 
passing scores required, the format of questions or the number 
of versions of tests. EPA's goal was to stimulate the development 
of a number of certification programs designed to meet the diverse 
needs of the technician community. For example, the Agency is 
aware that several open-book, unproctored tests and closed-book, 
proctored programs have been developed. Some programs use video 
training, while others stress written material or hands-on
demonstration. 
As stated in the proposal, the number and format of test questions 
may vary depending on the testing scheme employed. At the same 
time, the questions must be adequate to cover the subject material 
in sufficient depth and detail. Individual companies interested 
in providing a certification opportunity for their employees 
may develop a program that reflects their existing training 
structure and seek EPA approval under section 82.40. EPA's goal in 
reviewing programs will be to assess whether each program meets 
the minimum standards in section 82.40. The Agency encourages
programs 
to surpass the minimum standards and develop superior programs, 
but this is not a requirement.
   EPA specifically requested comment on the validity of open-
book testing for technician certification. Most commenters
supported 
open-book testing as a valid minimum testing procedure; however, 
many commenters stated that proctors should be required whether 
the tests are open-book or closed-book. Commenters questioned 
the validity and quality of unproctored testing.
   In developing standards for the certification of technicians 
under section 609, the Agency examined existing industry
certification 
programs such as ASE and MACS, as well as other types of testing 
formats, including correspondence courses. One program referred 
to in Section 609(b)(4), MACS, employs non-proctored exams. 
Given the large number of technicians dispersed through a multitude

of cities and towns in the country, and the Act's short statutory 
timeframes, the Agency believes that requiring proctored exams 
would require technicians to travel to a limited number of testing 
locations and would be infeasible for many technicians.
   The proposed test administration criteria would require that 
programs establish sufficient measures to assure that tests 
are completed honestly by technicians and that there are methods 
for assuring technician identity. Examples include requiring 
signatures of technicians on test forms, requesting social security

numbers, using multiple versions of tests and use of proctors 
in testing situations. Proctored exams are one, but not the 
only available method and certification programs are free to 
develop their combination of methods to assure valid testing. 
The Agency commends the procedures of many of the programs that 
have already been submitted to the Agency as effective yet not 
burdensome.
   In the September 4, 1991 notice, the Agency described how 
open-book testing, if structured properly, could result in
technicians 
having the necessary knowledge to properly perform refrigerant 
recovery and recycling, a subset of the knowledge needed to 
perform effective service on motor vehicle air conditioners. 
Several certification programs that have been developed incorporate

proctors and the Agency commends this action. As a minimum
standard, 
however, the Agency will allow technicians access to unproctored 
testing such as mail-in programs, assuming the test program 
meets all the criteria in section 82.40.
   The Agency received several comments on the proposed requirement

that completed tests be sent to an independent testing authority 
for grading. Commenters questioned whether any real benefit 
was obtained from such a requirement, since open-book, unproctored 
tests would be allowed. The requirement was also considered 
costly and unnecessary. Commenters sought clarification on various 
points, such as whether a non-profit entity associated with 
the sponsoring certification program would be an independent 
testing authority for grading.
   EPA originally proposed this requirement, on the advice of 
motor vehicle air conditioning industry representatives, to 
avoid certification programs that did not actually test learning 
of material presented but merely provided a "certificate of 
attendance". The Agency also sought to minimize the potential 
conflicts of interest that might arise, such as in certification 
programs that wish to guarantee certification or individual 
companies that have a vested interest in assuring all employees 
pass the test. The concept of an independent testing authority 
was based on both programs mentioned in section 609 of the statute,

which incorporate grading services or computerized grading of 
their existing exams. The goal was to incorporate neutrality 
into the grading process.
   The Agency continues to believe that neutrality in the grading 
process is an important goal. To clarify the regulatory language, 
section 82.40 will be changed to state "Completed tests must be
graded 
by an entity or individual who receives no benefit from the 
outcome of testing; a fee may be charged for grading". Programs 
submitted for EPA approval must demonstrate that the grading 
entity is neutral. Examples of independent grading include a 
scoring establishment which is a separate non-profit association 
associated with the sponsoring certification program, a contracted 
grading company or individual and computerized grading services.
   The Agency wishes to clarify that although it supports
certification 
programs making provisions for non-English speaking technicians 
(indeed there is a great need for these provisions in certain 
areas of the country), this is not a requirement. The Agency 
does commend the efforts of the programs that have already made 
progress in this area.

4. Technical Revisions

   Two commenters stated that the proposed requirement to review 
certification programs periodically and submit a written summary 
of the review and any changes to the Administrator every two 
years was excessive. They recommended that review of program 
content should only be triggered by the introduction of new 
equipment or refrigerants. The Agency believes the nature of 
the motor vehicle air conditioning market is rapidly changing, 
as evidenced by the development of the SAE J2209 standard for 
recovery only equipment. In this context, EPA has determined 
to keep the review provision as proposed. The Agency fully
anticipates 
that certification programs will review and revise their program 
content more often than every two years (for example, each time 
they order reprints of instructional material or tests) in order 
to stay current in the field. Requiring these updates to be 
reported to the Administrator assures accuracy of information 
and maintains parity among programs.

5. Recertification

   Two commenters favored EPA's proposal that it would reserve 
the right to require recertification of technicians in the future, 
if necessary. Three commenters maintained that periodic
recertification 
would be unnecessary, burdensome and beyond the intent of the 
Act.
   EPA believes the need to retest and recertify technicians 
in the future should be limited because certification programs 
are required to address the anticipated changes in motor vehicle 
air conditioning and to periodically review their programs. 
However, the Agency believes it is important to reserve the 
right to require recertification if environmentally significant 
changes in equipment for motor vehicle air conditioning occur.

6. Proof of Certification

   No commenters disagreed with the proposed requirement that 
each training and certification program offer individual proof 
of certification upon successful completion of the test. Proof 
of certification is essential for the purchase of small containers 
of class I or class II substances. Several commenters disagreed 
with or questioned the related proposal that unique numbers 
be provided for each certified technician by certification
programs.
   Several programs already use the technician's social security 
number as a unique number, while other programs number tests 
distributed for their own recordkeeping purposes and then assign 
that number to the technician when he or she successfully completes

the exam. Agency inspectors may need access to technician
certification 
numbers to verify compliance with the regulation. In addition, 
the Agency may need these numbers to prove non-compliance with 
the regulations in an enforcement action. Unique numbers will 
aid in meeting these compliance and enforcement activities. 
In addition, it presents little if any burden on these programs 
to provide such unique numbers. Unique numbers within programs 
are also needed to distinguish between technicians with the 
same name. Programs must only assure that the numbers assigned 
within their own programs are unique. EPA will not provide these 
numbers, and will not require that the numbers be reported to 
EPA by technician certification programs because of the
administrative 
burden associated with this activity on a national basis, and 
the need to coordinate between several programs.

7. Approval of Programs

   The Agency is aware of three technician certification programs 
that have already certified several thousand technicians. One 
program, given by the Mobile Air Conditioning Society, was
developed 
as part of the voluntary program established before the 1990 
amendments to the Act. Two programs, given by the International 
Mobile Air Conditioning Association and the National Institute 
of Automotive Service Exellence, were developed in advance of 
the proposed rule. Several programs, including these three, 
applied for approval under section 82.40. EPA has completed its
review 
of these three applications, and based on this review, EPA has 
formally approved them as technician training and certification 
programs. This approval will be effective as of August 13, 1992.
   Two aspects of this approval should be noted. First, in light 
of the fact that these programs have already trained and certified 
numerous technicians, training and certification conducted by 
these programs prior to the effective date of the approval will 
be considered valid for purposes of these regulations as long 
as the training and certification was conducted in conformity 
with the training and certification program approved by EPA. 
The earliest date for which the Agency will accept training 
under these requirements will be September, 1990, which the 
Agency understands to be the date that the first technicians 
were certified under the MACS program. Second, all training 
and certification conducted after the effective date of any 
standards adopted for recover only equipment (Appendix B) must 
cover such standards in the training and testing. Since the 
procedures for extraction of refrigerant are very similar for 
both recover/recycle equipment and recover only equipment, EPA 
expects that technicians trained and certified by these programs 
prior to the final adoption of recover only standards would 
not need to be retrained and recertified with respect to the 
appendix B standards. That issue, however, will be addressed 
when EPA promulgates the final appendix B standards At this 
time, the Agency believes that programs should incorporate the 
specifics of the labeling of containers of recovered refrigerant 
into certification programs as soon as possible. The Agency 
encourages recover only equipment salespersons to reiterate 
to technicians that equipment meeting the SAE J2209 standard 
does not clean refrigerant and thus refrigerant captured with 
these machines must be recycled or sent to a reclamation facility, 
as specified in EPA's definition for the proper use of such 
equipment.
   Several commenters questioned whether programs approved by 
states or localities were automatically approved by the EPA. 
Commenters also suggested that EPA accept state approved programs 
where the state standards are either substantially equivalent 
or more stringent than the Federal requirements.
   Certification by a state program is not a substitute for 
training and certification by a Federally approved program. 
The Federal requirements established by section 609 of the Act 
and these regulations are separate and distinct from any valid 
state laws or regulations that may apply. Compliance with one 
does not automatically guarantee compliance with the other. 
At the same time, state-approved programs may apply to EPA for 
approval under EPA's regulations. Approval by EPA of such a 
program will be based on compliance with the requirements of 
section 82.40, which may be more or less stringent than applicable 
state requirements.
   The Agency is aware of three state or local technician
certification 
regulations (Florida, Wisconsin, and the South Coast Air Quality 
Management District in California). EPA will work with the relevant

entities to review the requirements of their regulations and 
the approval process of any technician certification programs 
not already reviewed by the Agency to assure that no program 
falls below the minimum Federal standards.
   The Agency is aware that some states may have approved
technician 
certification programs in advance of promulgation of the EPA 
requirements using criteria different than the proposed Federal 
criteria. EPA also believes these differences are limited to 
the Test Administration criteria contained in section 82.40. With
this 
problem in mind, EPA believes it is reasonable to modify section
82.40 
to authorize approval of a training and certification program 
that meets all but the Test Administration criteria of that 
section. This would be allowed, however, only if the program, 
when viewed as a whole, is as or more effective than a program 
that does meet all of those criteria.{12}
      ³{12} To avoid confusion, it is important to note that 
      ³although this provision is made in response to comments

      ³concerning state approved programs, the revision to the

      ³Test Administration criteria is not limited to such
programs.
   EPA is taking this action for several reasons. First, EPA 
is aware that the statute and these regulations require the 
training and certification of a large number of technicians 
in a short period of time. These state-approved programs, as 
well as a variety of other programs, have already started this 
process to meet Federal and/or state or local requirements. 
This provision should allow additional flexibility in meeting 
these training and certification requirements, and will avoid 
penalizing activities conducted prior to the promulgation of 
these regulations. Second, programs approved under this provision 
can be expected to provide the same or better quality of training 
and exhibit the same or better level of validity in the
certification 
process, since the program will have to show EPA that when viewed 
as a whole it is as good or better than programs which meet 
all of the criteria.
   EPA has decided to limit this provision, however, to training 
and certification provided prior to the effective date of these 
regulations. After that date, all programs will have had adequate 
notice of the Federal requirements. This is especially so given 
that little change is being made from the September proposal. 
Programs will also have received adequate time to conform their 
program to these requirements. Limitation of this provision 
to such earlier training will also help to ensure that all approved

programs meet common requirements, increasing the consistency 
of test administration in approved programs. For more discussion 
of the relationship between state and Federal requirements, 
see section III.G.
   Since the publication of the proposed rule, the Agency has 
received other technician certification program applications 
and these will be reviewed as quickly as possible upon receipt 
of complete application materials. To facilitate EPA review, 
each program requesting review should supply information
illustrating 
how each element of the certification criteria in section 82.40 is 
met. This includes test questions, test administration and training

information such as videos or self-study booklets. The Agency 
encourages submission of applications for approval from training 
certification programs and will make every effort to review 
programs quickly. EPA will maintain a list of all approved programs

including both national testing programs and any individual 
company programs that are approved.

E. Small Container Restrictions

   The Act makes it unlawful, effective November 15, 1992, for 
any person to sell or distribute, or offer for sale or
distribution, 
any class I or class II substance suitable for use as a refrigerant

in motor vehicle air conditioning systems in a container with 
less than 20 pounds of refrigerant except to certified technicians 
servicing motor vehicles for consideration. The Agency proposed 
an implementation approach distinguishing between purchasing 
refrigerant in small containers for use and purchasing refrigerant 
in small containers for the purpose of resale only. For resale, 
the Agency proposed that sellers obtain a signed statement from 
purchasers stating that the small containers are for resale 
only. At retail sales outlets, the Agency proposed that sellers 
review the technician certification and keep a record of the 
technician's name, technician certification number and program 
name, date of sale and the quantity (number and size) of containers

purchased. The proposal also stated that outlets selling small 
containers must display a sign stating that it is unlawful to 
sell small containers to an individual who is not a properly 
trained and certified technician.
   Six commenters believed the continued existence of small 
containers allowed too great a potential for "do-it-yourselfer" 
access to refrigerant and that therefore the containers should 
be eliminated. Three commenters stated that the availability 
of small containers of CFC-12 increases the likelihood that 
the refrigerant supply will be contaminated because HCFC-22 
and HFC-134a are also available in small containers. One commenter 
mentioned that if sales to retail outlets were eliminated, the 
effectiveness of recycling efforts would be increased. Five 
commenters believed the sales restriction should be expanded 
to all size containers.
   EPA does not have authority under section 609 of the Act 
to ban or otherwise eliminate all small containers. The regulatory 
language in subpart B is designed to implement a specific statutory

provision concerning small containers. That provision does not 
ban, but only limits the sale of such small containers. The 
Agency, however, is concerned about the potential problems that 
the continued availability of small containers of refrigerants 
could cause, as suggested in the comments. Mixing refrigerants 
may lead to air conditioning systems failures and may also
subsequently 
contaminate recycle and recover equipment. The Agency is also 
aware that do-it-yourselfers may lawfully purchase containers 
with over 20 pounds of refrigerant. EPA will review this situation 
after gaining some experience with the operation of today's 
rule. It is important to note that several states have completely 
banned the sale of small containers.
   The Agency received one comment supporting the requirement 
that a sign be posted at the point of refrigerant sale for its 
educational and deterrence value. One comment stated that the 
requirement was redundant because the small containers would 
not be available to the general public, and one comment suggested 
that a label on the container was more appropriate than a sign. 
The Agency wishes to clarify that the intent of the retail sign 
is to alert the public to the sales restriction under section 
609 of the Act. Labeling requirements alerting consumers to 
products containing or made with class I and class II substances 
are being developed under section 611 of the Act and will not 
be redundant with the section 609 sales restrictions. For these 
reasons, EPA has determined to keep the requirement for a retail 
sign. EPA has clarified the regulation to state that the sign 
must be located where the sales occur.
   Several commenters addressed the proposed recordkeeping
requirements. 
The Automative Refrigerant Products Institute (ARPI) suggested 
that, at the wholesale level, purchasers be permitted to offer 
a one-time signed statement stating that cans are intended for 
retail sale in situations where sellers and purchasers have 
several transactions over time. The seller would keep the statement

on file. The Agency agrees that this would be an efficient
implementation 
method. No changes have been made to the regulations, however, 
because such actions would be allowed under the regulations 
as written.
   ARPI also suggested that equipment registration certifications, 
instead of technician certifications, be used in recordkeeping 
for small container purchases. Although service establishments 
must submit information to the Agency concerning the type of 
equipment they have purchased, the Agency will not send back 
a verified proof of equipment purchase. As a result, there is 
no equipment registration certification that could be used for 
recordkeeping as ARPI suggested. Proof of certification will 
be provided by the technician certification programs and therefore,

other than the purchase for resale, certified technicians are 
the only individuals permitted to purchase small containers.
   Two commenters stated that retail purchasers should be required 
to simply present valid proof of certification at the time of 
purchase, with no additional recordkeeping required at the retail 
level. Upon further consideration, the Agency agrees that the 
recordkeeping requirements are not essential to determine
compliance 
and develop effective enforcement actions. For example, if
necessary, 
EPA may review the normal records maintained by a business when 
circumstances lead EPA to believe a violation may have occurred. 
EPA has therefore deleted the recordkeeping for retail purchase 
from the final requirements published today.
   The Agency received several comments on the residual amount 
of CFC-12 remaining in cans after use, the standard of purity 
used by small container manufacturers, and the dispensing mechanism

of the containers themselves. The Agency continues to be concerned 
about this aspect of the use of small containers and will further 
consider these comments when developing lowest achievable emission 
levels under section 608 of the Act.

F. Equipment Certification and Small Entity Certification


1. Certification Dates

   As noted earlier, the statute requires that, after January 
1, 1992, no person repairing or servicing a motor vehicle for 
consideration may perform any service on a motor vehicle air 
conditioner involving the refrigerant unless they properly use 
approved equipment. In addition, the repair or service personnel 
must have been properly trained and certified for such work. 
The statute grants a one year extension to small service
establishments-
establishments that performed less than 100 service jobs involving 
refrigerant in the year 1990. This one year extension is only 
available if the small service establishment certifies to the 
Administrator on or before January 1, 1992 that they meet the 
requirements for this extension.
   All persons performing service on motor vehicle air conditioners

for consideration, notwithstanding the size of the establishment, 
must certify to the Administrator on or before January 1, 1993 
that they have purchased approved equipment and that authorized 
service personnel have been properly trained and certified.
   One commenter expressed concern that the one year delay between 
the requirement to use approved equipment for servicing (except 
small shops) and the requirement to certify the purchase and 
use of such equipment could result in reduced compliance. The 
commenter recognized that the difference in dates stems from 
section 609(c) and 609(d), and suggested that EPA increase
compliance 
through education and enforcement.
   EPA would like to encourage establishments to certify that 
they own equipment before January 1, 1993. The Agency applauds 
the efforts of the hundreds of service entities that have already 
submitted their equipment registrations to the Agency. The Agency 
has also received hundreds of the small establishment
certifications. 
Once the certifications are filed with the Agency, the small 
establishments have until January 1, 1993 to purchase equipment. 
As discussed in section V. on effective dates, EPA enforcement 
actions may be taken as of the effective date of this regulation.
   Several commenters were concerned that the small entity
extension 
is too easy to obtain. Two commenters suggested that the small 
establishments be required to submit substantially more information

than proposed on the motor vehicle air conditioner service jobs 
they performed in 1990, such as vehicle make, model, engine 
size and CFC charge remaining, before they are granted an
extension. 
The Agency believes that the intent of Congress in including 
this specific small establishment extension was to reduce the 
regulatory burden on small entities. Requiring small entities 
to supply substantially more information could significantly 
reduce the relief Congress sought to provide. Moreover, the 
additional information that commenters suggested EPA collect 
would not provide significantly greater assurance that the numbers 
of service jobs reported by small entities was accurate. The 
Agency will therefore not require the suggested service record 
submittal for small entities. However, the Agency may examine 
an establishment's records supporting its certification that 
it performed less than 100 service jobs in 1990. If warranted, 
appropriate enforcement action may be taken.
   In additional comments received after the end of the comment 
period, the State of Oregon requested that EPA consider exempting 
very small service establishments from all requirements. They 
classify the very small establishments as those performing under 
20 jobs involving refrigerant per year. Oregon is considering 
establishing this exemption in its own program based on several 
factors; the state's belief that small service establishments 
will not voluntarily undertake recycling because of the high 
cost of the equipment and the fact that the small number of 
service jobs the shop performs will make it difficult for them 
to make a return on their investment. The amount of refrigerant 
released by these shops would be small and Oregon suggests that 
the compliance rates for these shops will be low if an exclusion 
is not granted.
   Congress clearly recognized that small service establishments 
merited special consideration and included the one year extension 
for the equipment requirements. By implication, Congress also 
considered that no further relief was necessary or appropriate. 
The Agency, moreover, does not believe the establishment of 
any "de minimis" number of service jobs is warranted. The Agency 
recognizes that small service establishments may determine that 
the small number of jobs involving refrigerant that they perform 
do not justify continuing to perform service and purchasing 
the equipment. They may choose to decline this type of work 
or arrange to have the refrigerant removed from the motor vehicle 
air conditioner at a service location that does have the
appropriate 
equipment before they perform service. The small establishment 
may also consider the purchase of recover only equipment, which 
is typically less expensive than recover/recycle equipment. 
The sale of any recovered refrigerant to a reclamation facility 
will also help the entity recoup the cost of the investment. 
The Agency also wishes to highlight the fact that a significant 
amount of recover/recycle equipment was sold before enactment 
of the Act on the basis of the industry voluntary program. Although

most of the equipment was purchased by larger service
establishments 
such as dealerships, the estimates of the equipment sold indicate 
that some smaller service establishments also purchased equipment 
voluntarily. The Agency believes the flexible nature of this 
final regulation and the inclusion of the one year extension 
for small service establishments provide for appropriate relief 
for these entities and no further measures are necessary.

2. Example Form

   In the proposed rule, EPA included an example form to illustrate

the type of information necessary to certify equipment to the 
Agency. Equipment owners are not required to use the form to 
certify; it is provided as an example only. One commenter
questioned 
whether the proposed example form can be used to certify recover 
only equipment to the Agency. To clarify that the example form 
may be used for either type of equipment, the form has been 
revised to include the words "or recover" wherever the form 
states recover/recycle equipment. It should be noted, however, 
that EPA has not yet finalized the standards for approval of 
recover only equipment. Until that time, the only equipment 
officially approved by EPA is recover/recycle equipment certified 
to meet the standards of appendix A. The only other change to 
the example form provided in the proposal is the replacement 
of the acronym "MACs" with the more accurate "MVAC" for motor 
vehicle air conditioner. One commenter mentioned that MACs could 
be confused with the name of the Mobile Air Conditioning Society 
(MACS). The revised form appears as Example A in today's notice. 
Any certifications received using the proposed form are acceptable 
because, as stated in the proposal, the form is intended for 
guidance and the Agency does not require establishments to report 
in this format. The data elements for reporting remain the same 
as the proposal: the serial number of each unit of equipment, 
the name of the purchaser of equipment and the address of the 
establishment where the equipment will be located, the manufacturer

name, model number, date of manufacture, and a signed statement 
that each individual authorized to perform service using the 
equipment is properly trained and certified and that the equipment 
will be properly used in servicing motor vehicle air conditioners.
   Small establishments may also use the example form to certify 
that they performed less than 100 service jobs involving
refrigerant 
in 1990. All certifications, both equipment and small entity, 
should be sent to the following address: MVACs Recycling Program 
Manager, Stratospheric Ozone Protection Branch (6202-J), U.S. 
Environmental Protection Agency, 401 M Street, SW., Washington, 
DC 20460.

G. Relationship to State Regulations

   In the proposed notice, the Agency stated that the Act does 
not provide for Federal preemption of state requirements. The 
rule published here today represents the Federal requirements 
applicable to the servicing of motor vehicle air conditioners, 
and states or localities may establish programs with different 
requirements to the extent otherwise consistent with the United 
States Constitution. EPA is aware of several states with their 
own programs, e.g. Florida and Oregon, and in most cases the 
programs contain requirements that mirror the Federal program. 
The Agency would like to clarify that compliance with a state 
or local program may not in and of itself constitute compliance 
with the Federal standards. For example, regardless of state 
registration or permitting requirements, the service establishments

must certify their equipment with EPA (see section III.F.). 
Conversely, service entities and technicians in states or
localities 
with regulations that are effective in advance of the Federal 
program must comply with these earlier requirements in their 
state and locality.
   Regarding technician certification, as stated in section 
III.D., in cases where the state or locality has approved programs,

the Agency will work with the state or locality to minimize 
the burden of obtaining approval for these programs. The Agency 
encourages any programs that have been approved by a state or 
locality to submit those program for Federal approval. The Agency 
is aware that in many cases the programs approved at the Federal 
level may also be approved by the state or locality and, therefore,

no conflict would exist.
   The Agency is aware that some states have also performed 
"substantially identical equipment" reviews for equipment.
Equipment 
in those states also must be reviewed for applicability with 
the Federal requirements and EPA will work with the states to 
determine if their review criteria were appropriate.
   Eight commenters highlighted the importance of coordinated 
state and Federal activity and the Agency will work with states 
to coordinate and streamline the enforcement activities in states 
where programs exist.
   One commenter asked whether the State of Oregon's inclusion 
of wrecking yards in their recycling program would be superseded 
by the Federal requirements. Although the regulations published 
today do not include removal of CFCs from automobiles at disposal, 
the Agency intends to include requirements under the Safe Disposal 
Program within section 608 of the Act. The Federal regulations 
promulgated today do not preempt Oregon's requirements and, 
in fact, supports the state's efforts to develop a program. 
Leak detection efforts by the states of Wisconsin and Florida 
are other examples of requirements that EPA's program do not 
preempt.

H. Recordkeeping Requirements


1. Certification

   The proposed certification requirements were intended to 
establish records to assist EPA in its compliance and enforcement 
activities. Section 609(d) of the Act requires that persons 
performing service on motor vehicle air conditioners certify 
to the Agency that they have acquired and are properly using 
approved equipment. The Agency proposed that this certification 
include name and address of the establishment, the name of the 
manufacturer, the equipment model number, manufacturer date, 
and serial number. The proposed certificate also included a 
statement concerning the proper use of the equipment, and that 
authorized service personnel were properly trained and certified. 
Small service establishments must certify to the Agency that 
they did under 100 service jobs involving refrigerant in 1990 
if they wish to qualify for the one year extension described 
in section III.F.
   The Agency would like to clarify that the Agency will not 
issue permits or licenses to service establishments upon receipt 
of the equipment certification. Several commenters mistakenly 
suggested that permits or EPA certifications be used for the 
small container sales restrictions discussed in section III.E. 
As required in the Act, the small container sales restriction 
is based on the technician certification requirements. Service 
establishments that wish to verify EPA's receipt of their
certification 
may send the certification by certified mail. They may also 
wish to retain a copy.

2. Recordkeeping

   In the proposal, EPA attempted to develop requirements similar, 
in most cases, to the typical invoice or purchasing records 
maintained by a service entity. The Agency proposed that invoices 
kept upon service of motor vehicle air conditioners include 
the fact that service was performed, the name, address, and 
phone number of the vehicle owners, and the year, make, model 
and license plate numbers of the vehicles serviced, date of 
service, and the odometer reading of the vehicle. Owners of 
approved equipment would retain records of the amount of
refrigerant 
purchased and consumed each month and they retain records
demonstrating 
that all persons authorized to use the approved equipment are 
properly certified. The Agency also proposed that owners of 
approved recover only equipment maintain records of the refrigerant

sent to off-site reclaimers or recycled on-site.
   For the small container sales restriction, the Agency proposed 
that purchasers attest in writing that they are properly trained 
and certified. This writing would include the name of the
purchaser, 
their technician certification number, the date of sale, and 
the quantity of cans purchased. Under the proposal, the only 
exception to the requirement that purchasers of small containers 
be trained and certified is if the purchaser is purchasing the 
small containers for resale only and signs a statement to that 
effect.
   Several industry commenters noted that the proposed
recordkeeping 
requirements were written for the consumer vehicle repair industry 
and do not consider several specific circumstances. Examples 
include service on fleet vehicles and farm or construction
equipment 
where license plates, vehicle owner, or routine invoice procedures 
do not exist. As stated above, the Agency intended the proposed 
requirements to be as similar as possible to the types of
recordkeeping 
already being maintained for accounting purposes to minimize 
the burden of this regulation. The Agency acknowledges that 
the proposed requirements do not reflect all the servicing
situations 
that may occur nationally.
   Two commenters believed that the recordkeeping requirements 
were unnecessarily burdensome on small businesses that do not 
have the resources to create or complete new forms. One commenter 
specifically questioned whether the reconciliation of purchases 
and estimation of the volumes of recycled refrigerant was possible 
considering the various amounts of refrigerant that motor vehicle 
air conditioners may contain when they are serviced. The Agency's 
proposal included a provision requiring the maintenance of records 
on the amount of refrigerant purchased and consumed each month 
in order to allow the Agency to make a determination if refrigerant

was actually being recycled. The Agency agrees with the commenter 
that this recordkeeping requirement will not necessarily aid 
in determining whether recycling actually occurred. This
determination 
would be difficult to make because the Agency could only compare 
the records to statistics for the average amount of refrigerant 
remaining in motor vehicle air conditioners at service. The 
amount of refrigerant actually found in a particular system, 
however, is dependent upon the type of repair that must be made, 
for example automobiles involved in front-end accidents may 
well have lost their entire charge, while the amount of refrigerant

lost during normal use will vary between manufacturers and models 
of motor vehicles. The requirement that service establishments 
keep invoices of service performed and record their purchases 
and consumption of refrigerant, therefore, has been deleted 
in today's final rule.
   Several commenters addressed the tracking of off-site shipments 
to reclamation facilities, with some commenters suggesting more 
detailed tracking and others suggesting that all records of 
off-site shipments or on-site recycling were unnecessary. The 
Agency has determined that service establishments using recover 
only equipment should be required to keep records of where
refrigerant 
is sent for reclamation. Shops using recover only equipment 
that will have the refrigerant recycled by the owner must keep 
the name and address of the owner on-site. The Agency has decided 
it would not require in this regulation that service entities 
keep records of amounts of refrigerant sent and dates the shipments

have been made. The Agency would like to clarify that service 
establishments using recover equipment need not retain records 
of the amount of refrigerant recycled on-site, only the address 
of the off-site reclamation facility they are currently doing 
business with. Additional recordkeeping requirements proposed 
by EPA have been deleted as unnecessary. The records required 
by these regulations must be maintained on-site for three years 
for spot checks upon inspection. The records should not be
submitted 
to the Agency.
   As discussed in section III.E, the small container recordkeeping

requirements will not remain the same as proposed. Sellers of 
small containers of refrigerant must review the technician
certification 
of anyone purchasing small containers, however they are not 
required to maintain records of the technician name, technician 
certification program, technician certification number, the 
date of sale and the number of containers purchased. The only 
exception to this is if the purchaser is purchasing the cans 
for resale, then he must so certify to the seller in writing.

IV. Summary of Today's Final Rule

   This section briefly describes the provisions of today's 
final rule. Any changes made to the rule language as a result 
of the public comments are described. Various changes to the 
final rule that have been made for purposes of clarification 
are not described herein.

A. Authority

   The authority citation has been revised to reflect the most 
recent authority citation adopted by EPA for part 82.

B. Purpose and Scope (Section 82.30)

   This section states that these rules implement section 609 
of the Act and apply to persons performing service for
consideration 
on motor vehicle air conditioners. There were no changes to 
this section based on public comment. Minor editing changes 
were made for clarification.

C. Definitions (Section 82.32)

   This section contains the definition of the terms "approved 
independent standards testing organization", "approved refrigerant 
recycling equipment", "motor vehicle", "motor vehicle air
conditioners", 
"properly using", "refrigerant", "service for consideration", 
and "service involving refrigerant".
   The definitions for approved equipment and standards testing 
organization reference the sections of the rule (section 82.36 and 
section 82.38) described below. The motor vehicle definition was
limited 
to this subpart and the definition was changed to include those 
vehicles meeting the definition of motor vehicle used for purposes 
of title II of the Act. Also, the definition was clarified to 
specify motor vehicles where final assembly has been completed 
by the original equipment manufacturer. Motor vehicle air
conditioner 
defines the type of systems covered by this regulation and this 
definition was clarified to exclude buses using HCFC-22
refrigerant. 
The definition of refrigerant was clarified by including the 
language in the Act that states that effective November 15, 
1995, refrigerant shall include any substitutes for class I 
or class II substance. Service involving refrigerant defines 
the activities regulated. The service for consideration definition 
is intended to exclude "do-it-yourselfers" from the requirements 
of the regulation.
   The term "properly using" sets out the requirements for use 
of approved equipment. It states that technicians must follow 
the SAE J standard J1989 when operating equipment, as found 
in appendix A. For recover/recycle equipment, properly using 
includes recycling the refrigerant before reuse. For recover 
only equipment, properly using includes sending the refrigerant 
recovered to a reclamation facility or recycling it on-site 
if recycle equipment is available. Any refrigerant from reclamation

facilities used for the purpose of recharging motor vehicle 
air conditioners must be at or above the ARI 700-88 standard 
of purity. The definition also states that intentional venting 
of refrigerant is an improper use of equipment.
   The only change to the properly using definition is the addition

of a provision allowing the owner of a piece of recover only 
equipment to transfer the refrigerant off-site and recycle it 
using a piece of recover/recycle equipment owned by the same 
person.

D. Prohibitions (Section 82.34)

   There are three prohibitions in this final rule. The first 
requires that by January 1, 1992, persons performing service 
for consideration on motor vehicle air conditioners must properly 
use approved equipment. These persons must be trained and
certified. 
The requirements of this prohibition do not apply until January 
1, 1993, for service establishments that performed under 100 
service jobs involving refrigerant in 1990, and so certify to 
EPA.
   The second prohibition states that effective November 15, 
1992, no person may sell or distribute any class I or class 
II substance in a container with less than 20 pounds of refrigerant

that is suitable for use as a refrigerant in a motor vehicle 
air conditioner to any person unless that person is properly 
trained and certified, or certifies to the seller that the
containers 
are intended for resale only.
   The final prohibition states that no technician training 
program may issue certificates unless that program complies 
with all the standards in section 82.40. The three prohibitions
remain 
as originally proposed, except for clarifying language changes.

E. Approved Refrigerant Recycling Equipment (Section 82.36)

   This section describes the two types of equipment that meet 
the definition of approved equipment for use in servicing motor 
vehicle air conditioners. The first type of equipment recovers 
CFC-12 and recycles it on-site to the SAE standard J1991. The 
standards for certification of this type of equipment appear 
in appendix A.
   The second type of equipment only recovers refrigerant. As 
stated in the properly using definition, the recovered refrigerant 
must be sent to a reclamation facility or recycled on-site. 
The standard for this equipment was proposed as Appendix B on 
April 22, 1992. The appendix will be finalized upon completion 
of the analysis of the public comments. In finalizing the standards

for recover only equipment, appendix B, the Agency intends to 
also amend section 82.36 (a) and (b) to include references to
appendix 
B.
   This section also contains provisions allowing the Agency 
to determine if equipment is substantially identical to certified 
equipment. Equipment manufacturers or owners may submit
applications 
for approval which contain information on the equipment that 
indicates its capability to meet the standards in appendix A. 
EPA anticipates that a substantially identical determination 
will apply to appendix B. That issue, however, will be addressed 
when EPA promulgates the final appendix B standards. The Agency 
will maintain a list of approved equipment. This list is available 
to the public.

F. Approved Independent Standards Testing Organizations (Section 
82.38)

   This section establishes the criteria for approval of testing 
laboratories or organizations for equipment. Organizations must 
demonstrate that they have the experience and the appropriate 
equipment to perform testing. Various changes to this section 
between the proposed notice and today's final regulation were 
made for purposes of clarification. In finalizing the standards 
for recover only equipment, appendix B, the Agency intends to 
also amend section 82.38 (a) and (b) to include references to
appendix 
B.

G. Technician Training and Certification (Section 82.40)

   This section establishes the standards for programs approved 
to train and certify technicians. The standards cover training, 
the subject material that must be covered by each program, and 
minimum test administration procedures. Summaries of reviews 
of programs must be submitted every two years and programs must 
offer technicians proof of certification upon successful completion

of the test. Recertification of technicians is not required 
at this time.
   One change to this section is clarification of the term
independent 
testing authority to state "Completed tests must be graded by 
an entity or individual who receives no benefit from the outcome 
of testing; a fee may be charged for grading." This is not a 
substantive change in the requirements. Another change involves 
approval of organizations that meet all criteria except for 
the Test Administration criteria, if the program, when viewed 
as a whole, is as effective as a program that does meet all 
of these criteria. In finalizing the standards for recover only 
equipment, appendix B, the Agency intends to also amend section
82.40(a) 
to include references to appendix B. 
   The Administrator reserves the right to revoke approval if 
a program violates any of the requirements and inspectors may 
revoke a technician's certification if the technician is unable 
to properly use equipment upon inspection.

H. Certification and Recordkeeping Requirements

   This section states that no later than January 1, 1993,
establishments 
repairing or servicing motor vehicle air conditioners for
consideration 
must certify to the Agency that they have acquired and are properly

using approved equipment. The data elements required for
certification 
include the name of the purchaser of the equipment, the address 
of the service establishment, the name of the manufacturer, 
the model number of equipment, the date of manufacture and serial 
number. The owner of the equipment or another responsible officer 
must sign the certification stating that equipment will be properly

used by certified technicians. The certification must be sent 
to: MVACs Recycling Program Manager, Stratospheric Ozone Protection

Branch (6202-J), U.S. Environmental Protection Agency, 401 M 
Ss)treet, SW., Washington, DC 20460.
   The address is the same as proposed except the MACs acronym 
has been replaced with the more accurate MVAC acronym for motor 
vehicle air conditioners. Other clarifications have also been 
made. These are not substantive changes. 
   Service establishments that performed fewer than 100 service 
jobs involving refrigerant in 1990 may qualify for a one year 
extension by submitting a small establishment certification 
by January 1, 1992. This submittal must contain the name and 
address of the service establishment and a signed statement 
that the establishment performed under 100 service jobs in 1990. 
The statement must be sent to the address shown above.
Establishments 
must retain records to verify this, however those records should 
not be submitted to the Agency. The example form provided in 
the preamble may be used for both the equipment and small
establishment 
certification, although use of the form is not required.
   Recordkeeping requirements at the service establishment have 
been changed. The establishment need not retain invoices of 
motor vehicle air conditioner service. The requirement in the 
proposed rule to record the amount of refrigerant recycled on-
site (if recover only equipment is used and the refrigerant 
is not sent to a reclamation facility) has been deleted. The 
proposed requirement that service establishments retain records 
of the amount of refrigerant purchased and consumed each month 
has also been deleted in today's final rule. The service
establishments 
must retain records demonstrating that technicians authorized 
to use the equipment are certified and must maintain records 
identifying the reclamation facility that refrigerant is sent 
to.
   The recordkeeping requirements for sales of containers of 
less than 20 pounds of refrigerant have been deleted. The only 
exception to this requirement is if the purchaser is purchasing 
the small containers for resale. In that case, the seller must 
receive a written statement from the purchaser that the cans 
are for resale only. In all other cases, the seller must verify 
that the purchaser is properly trained and certified, and must 
have a reasonable basis to believe the information presented 
by the purchaser is accurate. Finally, a sign must be displayed 
at the point of sale of small containers stating that it is 
a violation of federal law to sell containers of class I and 
class II refrigerant in containers of less than 20 pounds to 
anyone who is not properly trained and certified.
   All records under this section must be retained for three 
years. EPA authorized representatives must be allowed access 
to records upon inspection.

I. Appendix A and Appendix B

   Appendix A contains the three SAE standards used to certify 
recover/recycle equipment. The SAE standard J1990 (Extraction 
and Recycle Equipment for Mobile Automotive Air Conditioning 
Systems) has been revised by SAE and the revised version is 
incorporated into today's final rule. As discussed in section 
III.B.1, SAE J1990 (1991) includes minor changes from SAE J1990 
(1989). 
   Appendix B was proposed on April 22, 1992. The appendix will 
be finalized after the completion of the public comment period. 

V. Effective Date

   The effective date for today's rule is August 13, 1992. Section 
82.34 of these regulations requires that after this date, no 
person repairing or servicing a motor vehicle for consideration 
may perform any service on a motor vehicle air conditioner
involving 
the refrigerant unless they properly use equipment approved 
pursuant to section 82.36 of these regulations. Any such repair or 
service personnel must have been properly trained and certified 
under section 82.40 of the regulations.
   The effective date of these rules does not, however, limit 
the lawful effect of various statutory prohibitions in section 
609 of the Act. These statutory prohibitions are not dependent 
on EPA rulemaking. For example, section 609(c) states that
"[e]ffective 
January 1, 1992, no person repairing or servicing motor vehicles 
for consideration may perform any service on a motor vehicle 
air conditioner involving the refrigerant for such air conditioner 
without properly using approved refrigerant recycling equipment 
and no such person may perform such service unless such person 
has been properly trained and certified." Section 609(c) also 
conditions the one year extension for small volume establishments 
on the filing of a certificate with the Administrator on or 
before January 1, 1992.
   The Agency received several comments requesting a "grace 
period" to allow enough time to purchase equipment and certify 
technicians. EPA is aware that it may have been impossible in 
practice for persons to fully comply with the section 690(c) 
requirements, given that this final rule was not promulgated 
until after January 1, 1992. The Agency is also aware that numerous

establishments purchased refrigerant recycling equipment in 
anticipation of these regulations, and had their technicians 
trained and certified. EPA has already received many equipment 
certificates as well as small volume establishment certificates. 
This program was developed in the context of a pre-existing 
voluntary recycling program that involved several industries, 
trade associations, and numerous business entities across the 
nation. In addition, Congress apparently envisioned a maximum 
of 45 days between promulgation of the regulation (November 
15, 1991) and the effective date of the statutory prohibition 
(January 1, 1992). The Agency will consider all of these factors 
when deciding whether to commence an enforcement action for 
violations of section 690(c) that occurred after January 1, 
1992, but before the effective date of this rule.

VI. Summary of Supporting Analyses


A. Regulatory Impact Analysis

   Executive Order No. 12291 requires the preparation of a
regulatory 
impact analysis for major rules, defined by the order as those 
likely to result in:
   (1) An annual effect on the economy of $100 million or more;
   (2) A major increase in costs or prices for consumers,
individual 
industries, Federal, state or local government agencies, or 
geographic industries; or
   (3) Significant adverse effects on competition, employment, 
investment, productivity, innovation, or on the ability of the 
United States-based enterprises to compete with foreign-based 
enterprises in domestic or export markets.
   The Agency has determined that this regulation does not meet 
the definition of a major rule under E.O. 12291. However, the 
Agency has prepared an analysis to assess the impact of the 
regulation (see Costs and Benefits of MACs Recycling, May 24, 
1991) which is available for review in the public docket for 
this rulemaking.
   The Clean Air Act requires the EPA to promulgate regulations 
to phase out the production of ozone depleting substances by 
the year 2000 (2002 for methyl chloroform). EPA prepared a
Regulatory 
Impact Analysis (RIA) under the requirements of E.O. 12291 to 
analyze the costs and benefits of the phaseout (see Regulatory 
Impact Analysis: Compliance with the Clean Air Act Provisions 
for the Protection of Stratospheric Ozone, December 21, 1990). 
A key result of this analysis is that with the imposition of 
the phase out of production coupled with an excise tax of CFCs 
(see Omnibus Trade Reconciliation Act, 1989), CFC-12 recycling 
would be fully implemented by service establishments by the 
year 1992 even without a specific regulatory requirement to 
do so. As a result, the overwhelming majority of costs of this 
regulation on CFC-12 recycling at service of motor vehicle air 
conditioners (e.g. capital cost of recycling equipment and annual 
operating costs) have already been attributed to the CFC phaseout 
and have been included in the Phaseout RIA. The Phaseout RIA 
does not, however, include the costs of motor vehicle air
conditioner 
service technician certification as required under the Act. 
The total cost of this requirement is determined to be
approximately 
$14.9 million, well under the $100 million cost threshold for 
a major rule. The Costs and Benefits of MAC Recycling provides 
some general costs and benefits that could be attributed to 
motor vehicle air conditioner recycling, however, these costs 
are not incremental to the costs of the phaseout.
   One commenter asserted that the regulatory requirements will 
result in an annual effect on the economy of $100 million or 
more. The Agency reiterates that the $100 million figure is 
intended to address incremental costs as a result of regulation, 
and as stated above the majority of the costs for this rulemaking 
have already been determined as part of the phase-out of ozone 
depleting substances. Attributing the cost of equipment purchase 
to this regulation would result in double counting of costs.
   The State of Oregon questioned the assumption within the 
phase-out RIA that service establishments would implement recycling

absent a specific requirement to do so. At the time the phase-
out RIA was developed, the Agency believed that service
establishments 
would undertake recycling for both economic and non-economic 
reasons. Non-economic reasons could include customers'
environmental 
concerns or development of industry service norms that include 
recycling (a result of the voluntary program). These assumptions 
have been verified to some extent by the fact that over 50,000 
pieces of recover/recycle equipment were sold prior to the end 
of 1990.

B. Regulatory Flexibility Analysis


1. Purpose

   The Regulatory Flexibility Act, 5 U.S.C. 601-612, requires 
that Federal agencies examine the impacts of their regulations 
on small entities. Under 5 U.S.C. 604(a), whenever an agency 
is required to publish a general notice of proposed rulemaking, 
it must prepare and make available for public comment an initial 
regulatory flexibility analysis (RFA). Such an analysis is not 
required if the head of an agency certifies that a rule will 
not have a significant economic impact on a substantial number 
of small entities, pursuant to 5 U.S.C. 605(b).
   The Agency has performed an initial regulatory flexibility 
analysis and determined that while this regulation affects a 
substantial number of small businesses, it does not impact a 
substantial number significantly. The analysis is found in appendix

A in the Costs and Benefits of MAC Recycling and is available 
for review in the docket. The methodology and results of the 
analysis are presented below.

2. Methodology and Results

   To examine the impacts on small businesses, EPA first
characterized 
the regulated community by identifying the SIC codes that would 
be involved in the servicing and repair of motor vehicle air 
conditioners. After determining the number of these entities 
that are classified as small by the Small Business Act (SBA), 
the Agency performed impact tests using sales, profits and cash 
flow measures. The analysis included least expensive and most 
expensive private cost scenarios for compliance that were developed

for the Costs and Benefits of MAC Recycling. The least expensive 
cost scenario assumed recover only equipment is purchased at 
a price of $1000 while the more expensive option assumes $3000 
recycle equipment is acquired. The analysis also takes the cost 
of filter changes, sending refrigerant out for reclamation, 
labor, and cost savings from using recycled refrigerant into 
account.
   The State of Oregon questioned the Agency's determination 
that 90 percent of establishments that perform service are small 
businesses and suggested that 50 percent is a more reasonable 
figure. Oregon offered no justification for the 50 percent figure, 
however and the Agency maintains that the original analysis, 
which closely followed the Small Business Administration guidelines

for determination of small business when performing regulatory 
flexibility analysis, is accurate.
   The analysis indicates that the number of small establishments 
impacted by the regulation ranges from 18 percent if the least 
expensive compliance option, purchasing equipment that recovers 
refrigerant for off-site reclamation, is chosen to 32 percent 
if the most expensive compliance option is chosen. The Agency 
believes that most small establishments will choose the least 
cost option. This analysis did not reflect the fact that over 
50,000 machines have already been sold based on the voluntary 
program developed by industry. The establishments that have 
purchased these machines will only have the incremental regulatory 
burden of technician certification. In addition, Congress has 
already established some flexibility for small establishments, 
defined as those entities that performed under 100 motor vehicle 
service jobs in 1990, by providing a one year extension on the 
requirement to purchase equipment.
   The Agency believes that the one year extension, the fact 
that some entities have already purchased equipment, and the 
existence of the lease cost option of purchasing recover only 
equipment will result in less than 18 percent of small
establishments 
being significantly impacted by this regulation. The Agency 
frequently defines a "significant number" of small entities 
as approximately 20 percent or more of small establishments. 
As a result, the Agency certifies that this regulation will 
not have an impact on a significant number of small entities, 
pursuant to 5 U.S.C. 605(b).

Appendix A to Part 82 Subpart B-Standard for Recycle/Recover 
Equipment

Appendix B to Part 82 Subpart B-Standard for Recover Equipment 
[Reserved]

section 82.30   Purpose and scope.

   (a) The purpose of these regulations is to implement section 
609 of the Clean Air Act, as amended (Act) regarding the servicing 
of motor vehicle air conditioners.
   (b) These regulations apply to any person performing service 
on a motor vehicle for consideration when this service involves 
the refrigerant in the motor vehicle air conditioner.

82.32   Definitions.

   (a) Approved Independent Standards Testing Organization means 
any organization which has applied for and received approval 
from the Administrator pursuant to section 82.38.
   (b) Approved Refrigerant Recycling Equipment means equipment 
certified by the Administrator or an organization approved under 
section 82.38 as meeting either one of the standards in section
82.36. Such 
equipment extracts and recycles refrigerant or extracts refrigerant

for recycling on-site or reclamation off-site.
   (c) Motor vehicle as used in this subpart means any vehicle 
which is self-propelled and designed for transporting persons 
or property on a street or highway, including but not limited 
to passenger cars, light duty vehicles, and heavy duty vehicles. 
This definition does not include a vehicle where final assembly 
of the vehicle has not been completed by the original equipment 
manufacturer.
   (d) Motor vehicle air conditioners means mechanical vapor 
compression refrigeration equipment used to cool the driver's 
or passenger's compartment of any motor vehicle. This definition 
is not intended to encompass the hermetically sealed refrigeration 
systems used on motor vehicles for refrigerated cargo and the 
air conditioning systems on passenger buses using HCFC-22
refrigerant.
   (e) Properly using means using equipment in conformity with 
Recommended Service Procedure for the Containment of R-12 (CFC-
12) set forth in appendix A to this subpart. In addition, this 
term includes operating the equipment in accordance with the 
manufacturer's guide to operation and maintenance and using 
the equipment only for the controlled substance for which the 
machine is designed. For equipment that extracts and recycles 
refrigerant, properly using also means to recycle refrigerant 
before it is returned to a motor vehicle air conditioner. For 
equipment that only recovers refrigerant, properly using includes 
the requirement to recycle the refrigerant on-site or send the 
refrigerant off-site for reclamation. Refrigerant from reclamation 
facilities that is used for the purpose of recharging motor 
vehicle air conditioners must be at or above the standard of 
purity developed by the Air-conditioning and Refrigeration
Institute 
(ARI 700-88) (available at 4301 North Fairfax Drive, Suite 425, 
Arlington, Virginia 22203) in effect as of November 15, 1990. 
Refrigerant may be recycled off-site only if the refrigerant 
is extracted using recover only equipment, and is subsequently 
recycled off-site by equipment owned by the person that owns 
both the recover only equipment and owns or operates the
establishment 
at which the refrigerant was extracted. In any event, approved 
equipment must be used to extract refrigerant prior to performing 
any service during which discharge of refrigerant from the motor 
vehicle air conditioner can reasonably be expected. Intentionally 
venting or disposing of refrigerant to the atmosphere is an 
improper use of equipment.
   (f) Refrigerant means any class I or class II substance used 
in a motor vehicle air conditioner. Class I and class II substances

are listed in part 82, subpart A, appendix A. Effective November 
15, 1995, refrigerant shall also include any substitute substance. 
   (g) Service for consideration means being paid to perform 
service, whether it is in cash, credit, goods, or services. 
This includes all service except that done for free. 
   (h) Service involving refrigerant means any service during 
which discharge or release of refrigerant from the motor vehicle 
air conditioner to the atmosphere can reasonably be expected 
to occur.

section 82.34   Prohibitions.

   (a) Effective August 13, 1992, no person repairing or servicing 
motor vehicles for consideration may perform any service on 
a motor vehicle air conditioner involving the refrigerant for 
such air conditioner
   (1) Without properly using equipment approved pursuant to 
section 82.36; and
   (2) Unless such person has been properly trained and certified 
by a technician certification program approved by the Administrator

pursuant to section 82.40.

The requirements of this paragraph do not apply until January 
1, 1993 for small entities who certify to the Administrator 
in accordance with section 82.42(a)(2).

distribute, 
or offer for sale or distribution, any class I or class II
substance 
that is suitable for use as a refrigerant in motor vehicle air-
conditioner and that is in a container which contains less than 
20 pounds of such refrigerant to any person unless that person 
is properly trained and certified under section 82.40 or intended
the 
containers for resale only, and so certifies to the seller under 
section 82.42(b)(4).
   (c) No technician training programs may issue certificates 
unless the program complies with all of the standards in section
82.40(a).

SAE Recommended Practice, SAE J1990 (1991){1}

0. Foreword
   Due to the CFC's damaging effect on the ozone layer, recycle 
of CFC-12 (R-12) used in mobile air-conditioning systems is 
required to replace system venting during normal service
operations. 
Establishing recycle specifications for R-12 will provide the 
same level of performance as new refrigerant.
      ³{1} This standard is appropriate for equipment
certified 
      ³after February 1, 1992. This equipment may be marked 
      ³design certified for compliance with SAE J1990 (1991). 
      ³The standard for approval for equipment certified on 
      ³or before February 1, 1992 is SAE J1990 (1989). This

the R-12 from the system being service, by reducing the system 
pressure below atmospheric to a minimum of 102 mm of mercury.
   7.2 To prevent overcharge, the equipment must be equipped 
to protect the tank used to store the recycled refrigerant with 
a shutoff device and a mechanical pressure relief valve.
   7.3 Portable refillable tanks or containers used in conjunction 
with this equipment must meet applicable Department of
Transportation 
(DOT) or Underwriters Laboratories (UL) Standards and be adaptable 
to existing refrigerant service and charging equipment.
   7.4 During operation, the equipment shall provide overfill 
protection to assure the storage container, internal or external, 
liquid fill does not exceed 80% of the tank's rated volume at 
21.1 øC (70 øF) per DOT standards, CFR title 49, section
173.304 and 
American Society of Mechanical Engineers.
   7.4.1 Additional Storage Tank Requirements.
   7.4.1.1 The cylinder valve shall comply with the standard

equipment and the release of the refrigerant when being
disconnected.
   7.7 The equipment must be able to separate the lubricant 
from the recovered refrigerant and accurately indicate the amount 
removed during the process, in 30 ml units. Refrigerant dissolves 
in lubricant sample. This creates the illusion that more lubricant 
has been recovered than actually has been. The equipment lubricant 
measuring system must take in account such dissolved refrigerant 
to prevent overcharging the vehicle system with lubricant. Note: 
Use only new lubricant to replace the amount removed during 
the recycle process. Used lubricant should be discarded per 
applicable federal, state, and local requirements.
   7.8 The equipment must be capable of continuous operation 
in ambient of 10 to 49 øC (50 to 120 øF).

Recommended Service Procedure for the Containment of R-12

1. Scope
   During service of mobile air-conditioning systems, containment 
of the refrigerant is important. This procedure provides service 
guidelines for technicians when repairing vehicles and operating 
equipment defined in SAE J1990.

2. References
SAE J1990, Extraction and Recycle Equipment for Mobile Automotive 
    Air-Conditioning Systems

3. Refrigerant Recovery Procedure
   3. 1 Connect the recovery unit service hoses, which shall 
have shutoff valves within 12 in (30 cm) of the service ends, 
to the vehicle air-conditioning system service ports.
   3.2 Operate the recovery equipment as covered by the equipment 
manufacturers recommended procedure.
   3.2.1 Start the recovery process and remove the refrigerant 
from the vehicle AC system. Operate the recovery unit until 
the vehicle system has been reduced from a pressure to a vacuum. 
With the recovery unit shut off for at least 5 min, determine 
that there is no refrigerant remaining in the vehicle AC system. 
If the vehicle system has pressure, additional recovery operation 
is required to remove the remaining refrigerant. Repeat the 
operation until the vehicle AC system vacuum level remains stable 
for 2 min.
   3.3 Close the valves in the service lines and then remove 
the service lines from the vehicle system. Proceed with the 
repair/service. If the recovery equipment has automatic closing 
valves, be sure they are properly operating.

4. Service With Manifold Gage Set
   4.1 Service hoses must have shutoff valves in the high, low, 
and center service hoses within 12 in (30 cm) of the service 
ends. Valves must be closed prior to hose removal from the air-
conditioning system. This will reduce the volume of refrigerant 
contained in the service hose that would otherwise be vented 
to atmosphere.
   4.2 During all service operations, the valves should be closed 
until connected to the vehicle air-conditioning system or the 
charging source to avoid introduction of air and to contain 
the refrigerant rather than vent open to atmosphere.
   4.3 When the manifold gage set is disconnected from the air-
conditioning system or when the center hose is moved to another 
device which cannot accept refrigerant pressure, the gage set 
hoses should first be attached to the reclaim equipment to recover 
the refrigerant from the hoses.

5. Recycled Refrigerant Checking Procedure for Stored Portable 
Auxiliary Container
   5.1 To determine if the recycled refrigerant container has 
excess noncondensable gases (air), the container must be stored 
at a temperature of 65øF (18.3øC) or above for a period
of time, 
12 h, protected from direct sun.
   5.2 Install a calibrated pressure gage, with 1 psig divisions 
(0.07 kg), to the container and determine the container pressure.
   5.3 With a calibrated thermometer, measure the air temperature 
within 4 in (10 cm) of the container surface.
   5.4 Compare the observed container pressure and air temperature 
to determine if the container exceeds the pressure limits found 
on Table 1, e.g., air temperature 70øF (21øC) pressure
must 
not exceed 80 psig (5.62 kg/cm2 ).

   5.5 If the container pressure is less than the Table 1 values 
and has been recycled, limits of noncondensable gases (air) 
have not been exceeded and the refrigerant may be used.
   5.6 If the pressure is greater than the range and the container 
contains recycled material, slowly vent from the top of the 
container a small amount of vapor into the recycle equipment 
until the pressure is less than the pressure shown on Table 
1.
   5.7 If the container still exceeds the pressure shown on 
Table 1, the entire contents of the container shall be recycled.

6. Containers for Storage of Recycled Refrigerant
   6.1 Recycled refrigerant should not be salvaged or stored 
in disposable refrigerant containers. This is the type of container

in which virgin refrigerant is sold. Use only DOT CFR title 
49 or UL approved storage containers for recycled refrigerant.
   6.2 Any container of recycled refrigerant that has been stored 
or transferred must be checked prior to use as defined in section 
5.

7. Transfer of Recycled Refrigerant
   7.1 When external portable containers are used for transfer, 
the container must be evacuated at least 27 in of vacuum (75 
mm Hg absolute pressure) prior to transfer of the recycled
refrigerant. 
External portable containers must meet DOT and UL standards.
   7.2 To prevent on-site overfilling when transferring to external

containers, the safe filling level must be controlled by weight 
and must not exceed 60% of container gross weight rating.

8. Disposal of Empty/Near Empty Containers
   8.1 Since all the refrigerant may not be removed from disposable

refrigerant containers during normal system charging procedures, 
empty/near empty container contents should be reclaimed prior 
to disposal of the container. 
   8.2 Attach the container to the recovery unit and remove 
the remaining refrigerant. When the container has been reduced 
from a pressure to a vacuum, the container valve can be closed. 
The container should be marked empty and is ready for disposal.
