Proposed Test Rule for Certain Chemicals on the ATSDR/EPA CERCLA
Priority List of Hazardous Substances; Extension of Comment Period

AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule; extension of comment period.

-----------------------------------------------------------------------

SUMMARY: EPA is hereby extending the comment period for a proposed rule
issued on October 20, 2006 (71 FR 61926) (FRL-8081-3), to require
testing for certain chemicals on the Agency for Toxic Substances and
Disease Registry (ATSDR)/EPA Priority List of Hazardous Substances to
March 19, 2007. This extension is being made as a result of a request
by a member of the public for additional time to submit comments.

DATES: Comments must be received on or before March 19, 2007. Your
request to present oral comments must be in writing and must be

SUPPLEMENTARY INFORMATION: This document extends the public comment
period established in the Federal Register issued on October 20, 2006
(71 FR 61926) (FRL-8081-3). In that document, EPA proposed to require
testing for certain chemicals on the ATSDR/EPA Priority List of
Hazardous Substances which is compiled under the Comprehensive
Environmental Response Compensation and Liability Act (CERCLA), and
solicited proposals for enforceable consent agreements (ECAs). EPA
proposed the test rule under section 4(a) of the Toxic Substances
Control Act (TSCA) that would require manufacturers (including
importers) and processors of four chemical substances (chloroethane,
hydrogen cyanide, methylene chloride, and sodium cyanide) to conduct
testing for certain health effects relating to the manufacture,
distribution in commerce, processing, use, or disposal of these
substances. The data that would be obtained under the testing program
are intended to be used to address health effects data needs identified
by ATSDR and EPA for these substances, which are among the hazardous
substances most frequently found at sites listed on the CERCLA National
Priorities List (NPL) and which are also hazardous air pollutants
(HAPs) under section 112 of the Clean Air Act (CAA). EPA solicited
proposals for ECAs involving the conduct of physiologically based
pharmacokinetics (PBPK) studies as an alternative to the testing
proposed in the rule, as appropriate. Alternatively, if ECA proposals
involving the conduct of PBPK studies are not received, or if received,
are not considered by the Agency to be adequate, EPA may consider ECA
proposals which cover some or all of the testing identified for a given
chemical in this proposed rule.
    EPA is hereby extending the comment period on the proposed rule,
which was set to end on December 19, 2006, to March 19, 2007. This
extension is being made as a result of a request by a member of the
public for additional time to submit comments.
    Please go to the proposed rule to review the details of the
Agency's proposed action and follow the instructions provided in the
proposed rule for how to comment. To view the electronic docket for
this proposed rule and submit comments on-line, please go to

action is EPA-HQ-OPPT-2002-0073.
