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

摘要

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.
