Protection of Stratospheric Ozone: Administrative Changes to 
Final Rule to Phase Out Ozone-Depleting Chemicals

AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.



SUMMARY: With this action, EPA amends the current regulation to phase 
out the production and consumption of most ozone-depleting substances. 
This action clarifies aspects of the regulation as provided under 
section 604 and 606 of the Clean Air Act Amendments of 1990 (CAA). To 
ensure an orderly phaseout of the production and consumption of 
chlorofluorocarbons (CFCs), carbon tetrachloride, methyl chloroform and 
hydrobromofluorocarbons in 1996, and of halons after 1994, this action 
alters the administrative requirements of the regulations so companies 
may continue to produce for special exempted uses. Today's action also 
clarifies administrative procedures to improve the efficiency of 
current reporting requirements and to reduce the burden on the affected 
companies. These actions continue to ensure compliance with Title VI of 
the CAA in a manner consistent with the United States' obligations 
under the Montreal Protocol on Substances that Deplete the Ozone Layer, 
as amended.
    Specifically, EPA changes the requirements for the post-phaseout 
period for transformation and destruction of ozone-depleting 
substances; establishes the framework for the post-phaseout production 
of exempted essential uses; revises the controls for imports of 
controlled substances that are used or recycled; eases the requirements 
for exporting substances to Article 5 countries; changes the allowance 
requirements for exports of ozone-depleting substances; clarifies the 
requirements for heels remaining in containers that are returning to 
the U.S.; provides a period of reconciliation in which allowance 
balances may be adjusted; and simplifies the recordkeeping and 
reporting requirements.
    The changes made in this rule ease the burden on industry, and will 
therefore limit the negative economic impact associated with the 
regulations previously promulgated under Sections 604 and 606, while 
maintaining the environmental benefits of the accelerated phaseout.

DATES: This rule is effective on May 10, 1995. Amendments to the 
requirements specifically addressing 1995 apply to the entire 1995 
control period.

I. Background

    The current regulatory requirements of the Stratospheric Ozone 
Protection Program that limit production and consumption of ozonedepleting 
substances were promulgated by the Environmental Protection 
Agency (EPA) in the Federal Register on December 10, 1993 (58 FR 
65018), and on December 30, 1993 (58 FR 69235). The requirements 
contained in these rules set out an Allowance Program (the Program) 
that was described in the notice of proposed rulemaking (NPRM) 
published in the Federal Register on November 10, 1994 (59 FR 56275). 
The preamble to the November 10, 1994 proposed rulemaking describes the 
history of the Program, the current requirements and the proposed 
amendments.
    The Allowance Program was designed to ensure that the U.S. meets 
its obligations under the Montreal Protocol on Substances that Deplete 
the Ozone Layer, as amended, (the Protocol) and to ensure compliance 
with Title VI of the Clean Air Act Amendments of 1990 (CAA). The 
Protocol and the CAA require the control and phaseout of production and 
consumption of ozone-depleting substances. In the Program, companies 
expend ``allowances'' when they produce or import ozone-depleting 
substances. With certain restrictions, the allowances can be traded 
among companies both domestically and internationally (between 
countries that are Parties to the Protocol). To control production, the 
Agency allocated baseline production allowances to producers of 
specific ozone-depleting chemicals. To control consumption, the Agency 
allocated baseline consumption allowances to producers and importers of 
specific ozone-depleting chemicals. Allowances for class I substances 
are currently provided to companies on an annual basis, except for 
halons whose production was phased out on January 1, 1994. The 
allowances are assigned to companies according to production and 
importation during base years.
    In the context of the Program, the use of the term consumption may 
be misleading. It is not the ``use'' of these substances that is 
controlled through regulation but rather the amount of the substance 
available for U.S. domestic consumption, defined as production plus 
imports minus exports of bulk virgin chemicals. Controlled substances 
produced or imported through the use of allowances prior to 1996 (1994 
for halons) can continue to be used by industry and the public after 
the phaseout.

II. Administrative Changes in the Stratospheric Protection Program

    The administrative changes in today's action modify the current 
regulation to ensure an orderly phaseout in 1996, so that companies may 
continue to produce for specified exempted uses permitted under the 
Protocol and the CAA. In addition, the Agency is seeking to improve the 
efficiency of the requirements and to reduce the burden on the affected 
companies while ensuring continued compliance with Title VI of the CAA 
and the Montreal [[Page 24971]] Protocol. In light of these objectives, 
the Agency is promulgating the following administrative changes to 
improve the Program.
    The NPRM published in the Federal Register on November 10, 1994, 
proposed changes to begin on January 1, 1996 for the post-phaseout 
period and also proposed changes for the 1995 control period.
    Under the current regulation, the phaseout of the production and 
consumption of the class I controlled substances (except Group VI, 
methyl bromide) will be complete by January 1, 1996. A list of the 
specific class I ozone-depleting chemicals in each Group can be found 
in appendices A and F to subpart A. The schedule for the phaseout of 
hydrochlorofluorocarbons was published in the Federal Register on 
December 10, 1993, and is unchanged in this final rule.
    Due to the phaseout, beginning January 1, 1996, production and 
consumption allowances for all class I controlled substances, except 
Group VI, methyl bromide, will no longer be used. Despite the 
discontinuation of such production and consumption allowances for class 
I controlled substances (except methyl bromide), the Agency envisions 
that the manufacture of class I controlled substances may continue 
after January 1, 1996, provided the substances are:
    <bullet> Either transformed or destroyed,
    <bullet> Produced for export to Article 5 countries,
    <bullet> Produced for essential uses as authorized by the Protocol 
and CAA and consistent with essential-use allowances, or
    <bullet> Produced with destruction and transformation credits.
    In addition, EPA envisions that the import of class I controlled 
substances (except methyl bromide) may continue after January 1, 1996, 
without the need for consumption allowances, if the substances are:
    <bullet> Either transformed or destroyed,
    <bullet> Previously used (including recycled or reclaimed),
    <bullet> Imported for essential uses as authorized by the Protocol 
and CAA and consistent with essential-use allowances,
    <bullet> Transhipped through the United States to another Party to 
the Protocol, or
    <bullet> Imported using destruction and transformation credits.
    Through today's final rule the Agency will:
    (1) Maintain a category of Article 5 allowances (previously called 
potential production allowances),
    (2) Create a new category of essential-use allowances, and
    (3) Create narrow procedures for granting destruction and 
transformation credits.
    EPA received twenty-two comments on the proposed rulemaking 
published in the Federal Register on November 10, 1994, as well as 
several additional submissions following the close of the comment 
period. All comments were reviewed and considered. Comments most 
relevant to today's action are responded to in the preamble and 
additional responses to comments are available in the Air Docket No. A-
92-13.

A. Program Requirements for Continued Post-Phaseout Production and 
Importation After January 1, 1996


 Post-Phaseout Requirements for Transformation and Destruction of 
Controlled Substances
    The following paragraphs discuss requirements for the destruction 
and transformation of controlled substances after the January 1, 1996 
phaseout date. EPA would like to be informed of new technologies for 
destruction of controlled substances that have been developed or are 
being developed since the Parties to the Protocol first approved the 
current list of destruction technologies. EPA would like to anticipate 
the future review of new technologies for destruction by the Parties to 
the Protocol.
    Definition of Emissive Use. In the preamble of the proposal (59 FR 
56278), EPA discussed a definition of ``emissive use'' that the Agency 
decided was unnecessary for today's action and provided no additional 
clarity to the regulation.
    a. Production or Importation of Controlled Substances Explicitly 
for Uses that Result in Transformation or Destruction after January 1, 
 In today's action, EPA permits companies to produce or import 
controlled substances if explicitly produced or imported for uses that 
will result in transformation or destruction in the United States or in 
a Party, after January 1, 1996.
    In the 1995 control period, controlled substances may continue to 
be produced explicitly for uses that result in transformation or 
destruction in the U.S. without the expenditure of allowances, as under 
the current regulation. Section C.3., ``Administrative Changes to 
Production Allowance Requirements for Exports that are Transformed or 
Destroyed,'' of this preamble discusses controlled substances produced 
in 1995 explicitly for export that results in transformation or 
destruction.
    Response to Comments: EPA received one comment that did not 
entirely support EPA's proposal to permit a company to produce or 
import after January 1, 1996, if explicitly for transformation or 
destruction. The commenter objected to maintaining procedures, after 
January 1, 1996, for companies that produce or import controlled 
substances explicitly for destruction in the U.S. (59 FR 56278). The 
commenter questioned the need for production, and especially 
importation, of controlled substances for destruction in the United 
States after the 1996 phaseout. This same commenter, however, did 
support the proposal to permit production and importation, after 
January 1, 1996, for transformation in the U.S.
    EPA is permitting production and importation explicitly for 
destruction after January 1, 1996, because industry commonly uses 
carbon tetrachloride and other controlled substances in chemical 
reactions until they lose their effectiveness and must be destroyed. In 
many chemical reactions, carbon tetrachloride is used as a catalyst or 
stabilizer. Once the reaction is complete, the carbon tetrachloride is 
withdrawn from the chemical being produced and used in the reaction of 
the next batch. Through these reactions, carbon tetrachloride loses its 
effectiveness as a catalyst or stabilizer and must eventually be 
destroyed. Many manufacturing processes rely on the unique 
characteristics of carbon tetrachloride, and other controlled 
substances, as catalysts or stabilizers but these chemical eventually 
need to be destroyed. EPA wishes to allow these manufacturing uses of 
controlled substances to continue after January 1, 1996, because they 
are not emissive uses, pose no significant threat to the environment 
and are vital to the U.S. economy.
    EPA received three comments seeking clarification of the 
requirements for production for export resulting in transformation 
after January 1, 1996. The proposal included a discussion, in section 
C.3.d. ``Administrative Changes to Production Allowance Requirements 
for Exports that are Transformed or Destroyed,'' (59 FR 56289) of 
requirements for the 1995 control period. However, the proposal did not 
explicitly define export requirements for the post-phaseout period.
    With this action, EPA permits production of class I controlled 
substances (except methyl bromide) after January 1, 1996, if the 
substance is explicitly produced for export or domestic uses resulting 
in transformation or destruction. As a [[Page 24972]] result, EPA 
requires producers and importers to receive an IRS certification of 
intent to transform or a destruction verification from all second- or 
third-party transformers or destroyers, whether the transformer or 
destroyer is domestic or foreign. Several U.S. companies commented that 
they currently use the IRS certificate of intent to transform in 
transactions with foreign transformers. For the sake of simplicity, 
these commenters suggested that the IRS certificate be required for all 
production and importation explicitly for uses resulting in 
transformation, whether they be foreign or domestic.
    Today's rule maintains the current requirement that producers and 
importers submit to EPA the IRS certificates of intent to transform, or 
the destruction verifications, with the quarterly reports (see Section 
C.7., Recordkeeping and Reporting). In response to comments and to ease 
the reporting burden on industry, EPA permits producers and importers 
to submit a one-time-per-control period IRS certificate for each 
customer. Quarterly reports may reference the original IRS certificate 
submitted for each transformer and simply list the quantity of 
subsequent sales.
    With today's rule, EPA maintains the current requirement published 
in the Federal Register on December 10, 1993, that quantities of class 
II controlled substances transformed or destroyed must be reported on a 
quarterly basis. EPA maintains the requirement to meet U.S. obligations 
under the Protocol to accurately monitor production of class II 
controlled substances.
    b. Production or Importation of Controlled Substances for Emissive 
Uses that are Subsequently Transformed or Destroyed. With today's 
action, EPA eliminates the specific provisions that grant additional 
production and consumption allowances, beginning January 1, 1996, for 
all class I controlled substances, except methyl bromide, produced for 
emissive uses but later transformed or destroyed. After January 1, 
1996, there will no longer be production or consumption allowances for 
class I controlled substances, except methyl bromide. After January 1, 
1996, a producer or importer of methyl bromide who expends production 
or consumption allowances and subsequently transforms or destroys the 
methyl bromide will still be able to petition the Agency for additional 
production and consumption allowances until the phaseout on January 1, 
2001.
    EPA maintains, for the 1995 control period, the provisions allowing 
producers and importers to petition the Agency for production and 
consumption allowances if the controlled substance was produced or 
imported with expended allowances and subsequently transformed or 
destroyed.
    Response to Comments: EPA received no comments regarding the 
proposal to eliminate procedures after January 1, 1996, that grant 
additional production and consumption allowances for class I controlled 
substances that are transformed or destroyed (except methyl bromide) 
(59 FR 56278). After January 1, 1996, additional production and 
consumption allowances may be sought for methyl bromide that is 
transformed or destroyed if it was originally produced with expended 
allowances.
    c. The Post-Phaseout Procedures for Granting Destruction and 
Transformation Credits. In today's action, EPA creates limited 
destruction and transformation credits to be granted after January 1, 
1996, for the destruction or the transformation in the United States of 
class I controlled substances (except methyl bromide) taken from a use 
system in the United States under certain circumstances. Destruction 
and transformation credits can only be obtained by entities whose 
applications are nominated by the U.S. government to the Protocol 
Secretariat for essential-use exemptions. The transformation and 
destruction credits are granted for the calculated amount of controlled 
substance transformed or destroyed minus a 15 percent offset.
    With today's action, an eligible person granted destruction and 
transformation credits by EPA for the destruction or transformation of 
an amount of a controlled substance taken from a U.S. use system may 
use the credits to newly produce or import the class I controlled 
substance for which they were nominated for an essential-use exemption. 
Today's action requires reporting on the source of material imported 
with credits. The reporting requirement is designed to deter abuse of 
credits as a means of illegally importing material as discussed in 
section B., ``Imports of Used Controlled Substances.''
    Response to Comments: EPA received six adverse comments, and three 
supportive comments to the proposal. EPA proposed (59 FR 56279) to 
grant destruction and transformation credits after January 1, 1996 to 
anyone who documents destruction or transformation of class I 
controlled substances (except methyl bromide) taken from a use system 
in the U.S.
    The comments challenging EPA's proposal expressed concern that 
granting destruction and transformation credits which can be used to 
produce or import virgin class I controlled substances (except methyl 
bromide) contradicts EPA's message of phasing out ozone-depleting 
substances and making the transition to alternatives. Four of the 
comments not supporting credits were from industry and the other two 
were from environmental groups.
    The comments challenged the proposed credits as violating U.S. 
obligations under the Protocol because they encourage production and 
importation of class I substances beyond the phaseout dates agreed to 
by Protocol Parties. The commenters challenged EPA's claim that 
environmental benefits would result from a scheme allowing continued 
production and importation beyond the phaseout, even if more than an 
equivalent amount of controlled substance were destroyed or 
transformed. EPA believes the Protocol allows production beyond the 
phaseout if the amount produced is equivalent to the amount destroyed 
by technologies approved by the Parties, as explained in the proposal's 
discussion (59 FR 56280) of the Protocol's definition of production. 
The proposal also discusses the environmental benefits of preventing 
release to the atmosphere of material by encouraging destruction or 
transformation of unwanted material in exchange for the production of 
material that will be used (59 FR 56281).
    A commenter cited Congressional legislative history from the 
drafting of the CAA that was unfavorable regarding destruction. 
Congressional debate included a statement that ``the Protocol's 
exclusion for manufactured substances that are subsequently destroyed 
is too broad and does not include adequate safeguards to preclude 
abuse.'' EPA recognizes the concerns expressed in the legislative 
history for the CAA and intends to offer these credits to a very 
limited universe of people.
    A commenter also pointed out that substances produced or imported 
with credits would be subject to the excise tax, eliminating the 
incentive to destroy or transform a material. A person would be paying 
a double tax. The tax would be paid on the original material and there 
would be a tax on the new material produced or imported with the 
credits. A commenter suggested that a tax credit or tax deduction would 
provide a greater financial incentive than the proposed credits. EPA 
acknowledges concerns about taxes and will therefore only grant credits 
when they are absolutely necessary.
    In response to comments on destruction and transformation credits, 
EPA is significantly limiting the [[Page 24973]] circumstances under 
which a person can obtain credits. With today's action, only a person 
that has exhibited an essential need for controlled substances beyond 
the phaseout date will be able to obtain destruction and transformation 
credits. EPA believes that only a person who has an essential need for 
a controlled substance should be eligible for credits that allow an 
exchange of destroyed or transformed existing material for the 
production or importation of new material.
    EPA today defines a person who has demonstrated the essential need 
for controlled substances beyond the phaseout, and can, therefore, 
obtain credits, as a person whose application was nominated by the U.S. 
government to the Protocol for an essential-use exemption. The 
nomination by the U.S. government defines eligibility for the credits, 
not the acceptance of the nomination by the Parties to the Protocol. 
For example, the U.S. Air Force's Titan Rocket has been nominated by 
the U.S. government for an essential use exemption and is therefore 
eligible for credits. A person who has been nominated to the Protocol 
for an essential-use exemption is eligible to be granted destruction 
and transformation credits after January 1, 1996, upon the destruction 
or transformation of a controlled substance taken from a use system in 
the U.S. Only for the control period(s) for which the U.S. government 
made nominations to the Protocol is a person eligible for the credits. 
If for some reason the nomination is revoked, the person's eligibility 
for credits is also revoked.
    EPA received three comments that suggested a larger offset than the 
15 percent proposed for destruction and transformation credits. The 
commenters challenged the 15 percent as being too small to provide an 
environmental benefit in a system that permits production or 
importation of new controlled substances after the phaseout. All three 
commenters suggested a 50 percent offset to ensure environmental 
benefits from the use of credits in the production or importation of 
new ozone-depleting substances. EPA justified the use of a 15 percent 
offset in the proposal citing environmental benefits (59 FR 56280) and 
basing the offset on current destruction capacity in the U.S (59 FR 
56281). EPA believes that today's action significantly limits the 
universe of people who can obtain credits. The limitation of who can 
obtain credits to those with a critical need, as defined by their 
essential-use nomination to the Protocol, significantly reduces the 
amount of production or importation of new material that will occur 
after the phaseout. EPA anticipates credits will only be sought and 
used in situations when one of the small number of people with critical 
needs encounters unforeseen circumstances or a catastrophic loss of 
material produced with essential-use allowances. With today's action, 
EPA will allocate credits equal to the calculated level of controlled 
substance destroyed or transformed minus the 15 percent offset. The 
destruction must occur in an approved destruction technology. An 
eligible person may request credits equal to 85 percent of the 
calculated level of controlled substance destroyed or transformed.
    EPA believes a person with an essential need for a controlled 
substance, as defined by a U.S. nomination to the Protocol, will view 
today's system of credits as an opportunity to satisfy critical needs, 
especially if material produced with essential-use allowances is lost 
to a catastrophe. EPA views today's action as a method to encourage the 
destruction or transformation of unwanted controlled substances that 
were taken from a use system in the U.S. that might otherwise be 
released to the atmosphere.
    EPA received many comments, from both industry and Federal 
agencies, challenging the use of credits for importing controlled 
substances after the phaseout as yet another opportunity for illegal 
imports. As discussed in the proposal (59 FR 56285), and below in this 
rulemaking, EPA is working to confront the illegal import of controlled 
substances. In 1994, EPA formed an inter-government task force with the 
Internal Revenue Service and the Customs Service to investigate illegal 
imports. An industry coalition formed a special committee to assist 
Federal agencies in investigating illegal imports. The efforts of 
government and industry have focused on the mislabelling of controlled 
substances and the submission of fraudulent documents that allow the 
illegal entry of imported controlled substances into U.S. commerce. In 
commenting on the proposed rule, both government and industry expressed 
concern that the use of credits for imports would be another chance for 
the submission of fraudulent documents. In response to these comments, 
EPA is requiring documentation of the source of imported material as 
required in Sec. 82.13(g)(2), where applicable.
    Clean Air Act Restrictions on the Use of Credits: With today's 
action, EPA limits the total amount of transformation credits and 
destruction credits that can be used in a control period to the 
production caps in the phaseout schedule of section 604 of the CAA, 
outlined in Table I.
