Proposed Test Rule for Hazardous Air Pollutants; Extension of Comment Period

摘要

EPA is extending the public comment period from September 30, 1997 to December 1, 1997, on the proposed rule published in the Federal Register of June 26, 1996 (61 FR 33178)(FRL-4869-1) requiring the testing of 21 hazardous air pollutants (HAPs) for certain health effects. This extension is needed to allow the Agency more time to amend the HAPs test rule proposal to reference eleven new Toxic Substances Control Act (TSCA) test guidelines and make other changes and clarifications to the proposed rule. DATES: Written comments on the proposed rule must be received by EPA on or before December 1, 1997.
