Thus, EPA stated that for'petitions to exempt individual metal-containing compounds from the EPCRA section 313 list of toxic chemicals, EPA bases its decisions on the evaluation of all System (IRIS) file pertaining to Copper (CAS No. 7440-50-8).

EPA stated that the Agency will deny petitions for chemicals that dissociate or react to generate the metal ion at levels which can reasonably be anticipated to cause adverse effects to human health or the environment and for which the 'metal ion availability cannot be properly characterized. In summary, EPA has determined that copper metal can reasonably be anticipated to cause a significant adverse effect on the environment of a sufficient seriousness to warrant continued reporting of copper under EPCRA section 313 because copper ion is available from copper metal and copper ion is highly toxic to aquatic organisms. Therefore, copper metal in ' all forms satisfies the criterion in EPCRA section 313(d)(2)(C). Accordingly, EPA is denying the petition. (9) USEPA, OPPTS. 1995.

All documents, including the references listed in Unit VL above and an index of the docket, SUMMARY: RPA 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 (EGAs) 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 toNovember 25, 1996.
