Proposed Test Rule for Hazardous Air Pollutants; Extension of
Comment Period on Proposed Rule and Extension of Period for Receipt of
Proposals for Enforceable Consent Agreements for Pharmacokinetics
Studies
AGENCY: Environmental Protection Agency (EPA).
ACTION: Extension of comment period on proposed test rule and extension
of period for receipt of proposals for enforceable consent agreements
for pharmacokinetics studies.
-----------------------------------------------------------------------
SUMMARY: EPA is extending the public comment period from December 23,
1996 to January 31, 1997 on the proposed rule to require manufacturers
and processors of 21 hazardous air pollutants (HAPs) to test these
substances for certain health effects. This proposed rule was published
in the Federal Register on June 26, 1996 (61 FR 33178) (FRL-4869-1). In
addition, the deadline for receipt of proposals for enforceable consent
agreements (ECAs) regarding the performance of pharmacokinetics (PK)
studies which would permit extrapolation from oral data to predict risk
from inhalation exposure for the HAPs is being extended from October
24, 1996 to November 25, 1996.
DATES: Written comments on the proposed rule must be received by EPA
on or before January 31, 1997. Written proposals for ECAs for PK
studies must be received by EPA on or before November 25, 1996.
ADDRESSES: Submit three copies of written comments on the proposed HAPs
test rule, identified by document control number (OPPTS-42187A; FRL-
[[Page 54384]]
4869-1) and three copies of proposals for PK studies, identified by
document control number (OPPTS-42187B; FRL-4869-1) to: U.S.
Environmental Protection Agency, Office of Pollution Prevention and
Toxics (OPPT), Document Control Office (7407), Rm. G-099, 401 M St.,
SW., Washington, DC, 20460.
A public version of the official rulemaking record supporting this
action, excluding confidential business information (CBI), is available
for inspection at the TSCA Nonconfidential Information Center, Rm. NE-
B607, 401 M St., SW., Washington, DC 20460, from 12 noon to 4 p.m.,
Monday through Friday, except on legal holidays.
All comments which contain information claimed as CBI must be
clearly marked as such. Three sanitized copies of any comments
containing information claimed as CBI must also be submitted and will
be placed in the public record for this rulemaking. Persons submitting
information any portion of which they believe is entitled to treatment
as CBI by EPA must assert a business confidentiality claim in
accordance with 40 CFR 2.203(b) for each such portion. This claim must
be made at the time that the information is submitted to EPA. If a
submitter does not assert a confidentiality claim at the time of
submission, EPA will consider this as a waiver of any confidentiality
claim and the information may be made available to the public by EPA
without further notice to the submitter.
Comments and data may also be submitted in electronic form by
sending electronic mail (e-mail) to: [email protected]. Such
comments and data must be submitted in an ASCII file avoiding the use
of special characters and any form of encryption. Comments and data
will also be accepted on disks in WordPerfect in 5.1 file format or
ASCII file format. All comments and data in electronic form must be
identified by (OPPTS-42187A)(FRL-4869-1). No information claimed as CBI
should be submitted through e-mail. Comments in electronic form may be
filed online at many federal depository libraries.
The official record of this action, as well as the public version,
will be maintained in paper form. EPA will transfer all comments
received electronically into paper form and will place the paper copies
in the official record. The official record is the paper record
maintained at the address listed at the beginning of the ``ADDRESSES''
section of this notice.

SUPPLEMENTARY INFORMATION: The HAPs rule proposed testing, under
section 4(a) of the Toxic Substances Control Act (TSCA), of: 1,1'-
biphenyl, carbonyl sulfide, chlorine, chlorobenzene, chloroprene,
cresols [3 isomers], diethanolamine, ethylbenzene, ethylene dichloride,
ethylene glycol, hydrochloric acid, hydrogen fluoride, maleic
anhydride, methyl isobutyl ketone, methyl methacrylate, naphthalene,
phenol, phthalic anhydride, 1,2,4-trichlorobenzene, 1,1,2-
trichloroethane, and vinylidene chloride. EPA would use the data
generated under the rule to implement several provisions of section 112
of the Clean Air Act and to meet other EPA data needs and those of
other Federal agencies. EPA is extending the period for public comment
on the proposed rule from December 23, 1996 to January 31, 1997.
In addition, in the HAPs proposal, EPA solicited proposals for ECAs
regarding the performance of pharmacokinetics studies which would
permit extrapolation from oral data to predict effects from inhalation
exposure. EPA is extending the period for receipt of proposals for ECAs
for PK studies from October 24, 1996 to November 25, 1996.
EPA is extending the period for submitting proposals for ECAs as a
result of requests by several members of the public for additional time
to submit such proposals. EPA is extending the comment period on the
proposed rule to allow adequate time for comments on the proposed rule
to be submitted after the Agency has considered the ECA proposals.
