SUPPLEMENTARY INFORMATION:
I. Electronic Availability
Internet: Electronic copies of this document and various support
documents are available from the EPA Home Page at the Federal
Register--Environmental Documents entry for this document under ``Laws
and Regulations'' (http://www.epa.gov/fedrgstr/EPA-TOX/1998/).
II. Background
EPA proposed health effects testing under TSCA section 4(a) on
June 26, 1996, for a number of HAPs chemicals (61 FR 33178) (FRL-4869-
1). As indicated in the proposed HAPs test rule, EPA would use the data
obtained from testing to implement several provisions of section 112 of
the Clean Air Act (CAA), including the determination of residual risk,
the estimation of the risks associated with accidental releases of
chemicals, and determinations whether substances should be removed from
the CAA section 112(b)(1) list of hazardous air pollutants (delisting).
The data also would be used by other Federal agencies (e.g. Agency for
Toxic Substances and Disease Registry (ATSDR), National Institute of
Occupational Safety and Health (NIOSH), Occupational Safety and Health
Administration (OSHA), and Consumer Product Safety Commission (CPSC))
in assessing chemical risks and in taking appropriate actions within
their programs.
In the proposed HAPs test rule, EPA invited the submission of
proposals for pharmacokinetics (PK) studies for the HAPs chemicals,
which could provide the basis for negotiation of ECAs. On December 24,
1997, in an amendment to the proposed HAPs test rule (62 FR 67466)
(FRL-5742-2), EPA provided the opportunity for the submission of ECA
proposals for alternative testing that could fulfill the testing needs
described in the proposed HAPs test rule, as amended. The Agency
indicated that such ECA proposals may or may not include PK and
mechanistic data development as a component of the alternative testing
proposal. EPA received alternative testing proposals to perform
reproductive toxicity testing for MIBK from the Ketones Panel of the
Chemical Manufacturers Association (CMA Ketones Panel) on December 11,
1996 and March 30, 1998. The Agency has completed its preliminary
review of the CMA Ketones Panel proposal and determined that there is
sufficient merit to proceed with ECA negotiations focussed specifically
on fulfilling the proposed HAPs test rule need for a 2-generation
reproduction study of MIBK. This was documented in subsequent
correspondence between EPA and the CMA Ketones Panel. A copy of the
proposal and correspondence is contained in the public record for this
ECA process. These materials will be
[[Page 32657]]
used during discussions at the negotiating meeting. EPA is hereby
initiating the procedures for ECA negotiations for the HAPs chemical,
MIBK. The procedures for ECA negotiations are described at 40 CFR
790.22(b).
The proposed HAPs test rule, as amended on December 24, 1997 (62
FR 67466) (FRL-5742-2) and on April 21, 1998 (63 FR 19694) (FRL-5780-
6), and the ECA negotiations on chemicals included in the proposed rule
are separate and parallel activities. While the Agency's objective of
obtaining data could be accomplished by either activity, EPA recognizes
that the final testing program performed by industry may differ
depending on whether it is accomplished under the final HAPs test rule
or via the ECA process. During the course of ECA negotiations,
additional information may be brought forward that could cause the
Agency to re-evaluate the nature of the testing requirements as stated
in the proposed HAPs test rule, as amended. This could result in the
development of an ECA that would fulfill the Agency's data needs in
ways not stated in the proposed HAPs test rule, as amended. It is
therefore essential for all interested parties to recognize these
differences at the outset and respond accordingly within the framework
of these two separate and parallel activities. Comments on the proposed
HAPs test rule, as amended, must be submitted under docket control
number, OPPTS-42187A, as described in the proposed HAPs test rule, as
amended, and will be addressed by EPA via the rulemaking process, which
is separate and distinct from the ECA process. Participation in the ECA
process is described in Units II. through IV. of this preamble.
Negotiations on developing an ECA for MIBK will focus on 2-
generation reproductive toxicity testing. The objective of the ECA
process is to conclude an ECA that will set in place industry-sponsored
testing that will adequately address EPA's data needs for the proposed
HAPs reproductive toxicity testing requirement for MIBK.
III. Identification of Interested Parties
EPA is soliciting interested parties to monitor or participate in
testing negotiations on an ECA for MIBK. The CMA Ketones Panel, the
submitter of the 2-generation reproduction study proposal for MIBK, and
the member companies of the CMA Ketones Panel are already considered
interested parties and do not need to respond to this document.
Additionally, any persons who respond to this document on or before
July 6, 1998 will be given the status of interested parties. Interested
parties must respond in writing to the address specified in the
``ADDRESSES'' section located at the beginning of this document. These
interested parties will not incur any obligations by being so
designated. Negotiations will be conducted in one or more meetings open
to the public. The negotiation time schedule for MIBK will be
established at the first negotiation meeting and will not exceed a
period of 4 months from the initial meeting. If an ECA is not
established in principle within this timeframe and EPA does not choose
to extend the negotiation time period, negotiations will be terminated
and testing will be required under the final HAPs test rule. If the
testing from the ECA does not meet the Agency's needs, EPA reserves the
right to proceed with rulemaking.
IV. Public Participation in Negotiations
Under EPA regulations, the Agency is required to provide the
public with an opportunity to comment on and participate in the
development of ECAs. The procedural rule for ECAs (40 CFR part 790)
contains provisions to ensure that the views of interested parties are
taken into account during the ECA process.
Individuals and groups who respond to this document will have the
status of interested parties. All negotiating meetings for the
development of this ECA for MIBK will be open to the public and minutes
of each meeting will be prepared by EPA and placed in the public docket
for this ECA process. The Agency will advise interested parties of
meeting dates and make available meeting minutes, testing proposals,
background documents, and other materials exchanged at or prepared for
negotiating meetings. Where tentative agreement is reached on
acceptable testing, a draft ECA will be made available for comment by
interested parties and, if necessary, EPA will hold a public meeting to
discuss any comments that have been received and determine whether
revisions to the ECA are appropriate. EPA will not reimburse costs
incurred by non-EPA participants in this ECA negotiation process.
ECAs will only be concluded where an agreement can be obtained
which is satisfactory to the Agency, manufacturers or processors who
are potential test sponsors, and other interested parties, concerning
the need for and scope of testing. In the absence of an ECA, EPA
reserves the right to proceed with rulemaking.
A. The Agency will not enter into an ECA if either:
1. EPA and affected manufacturers or processors cannot reach an
agreement on the provisions of the ECA; or
2. The draft ECA is considered inadequate by other interested
parties who have submitted timely written objections to the draft ECA.
B. EPA may reject these objections if the Agency concludes either
that:
1. They are not made in good faith;
2. They are untimely;
3. They are not related to the adequacy of the proposed testing or
other features of the agreement that may affect EPA's ability to
fulfill the goals and purposes of TSCA; or
4. They are not accompanied by a specific explanation of the
grounds on which the draft agreement is considered objectionable.
EPA will prepare an explanation of the basis for each ECA. The
explanatory document will summarize the agreement (including the
required testing), explain the objectives of the testing, and outline
the chemical's use and exposure characteristics. The document, which
will also announce the availability of the ECA, will be published in
the Federal Register.
V. Proposal of Export Notification Requirements for MIBK
EPA intends to publish a proposed rule in an upcoming Federal
Register document to require export notification by all persons who
export or intend to export MIBK under TSCA section 12(b) upon the
successful conclusion of an ECA for MIBK.
VI. Public Record and Electronic Submissions
As described above, MIBK is listed as a chemical that would be
subject to testing requirements under the proposed HAPs test rule, as
amended. This ECA negotiation process and the proposed rule, as
amended, are separate and parallel activities. The official record for
this ECA action on MIBK, including the public version, has been
