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.
