[Federal Register Volume 61, Number 203 (Friday, October 18, 1996)] [Proposed Rules] [Pages 54383-54384] From the Federal Register Online via the Government Publishing Office [www.gpo.gov] [FR Doc No: 96-26813] ----------------------------------------------------------------------- ENVIRONMENTAL PROTECTION AGENCY 40 CFR Part 799 [OPPTS-42187C; FRL-5571-3] RIN 2070-AC76 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. FOR FURTHER INFORMATION CONTACT: Susan B.

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.
