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: [e-mail]. 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.
