Copper Monochlorophthalocyanine Pigment; Toxic Chemical Release Reporting; Community Right-To-Know

概要

EPA is proposing to grant a petition to delete Color Index (C.I.) Pigment Blue 15:1 from the ``copper compounds'' category of the list of toxic chemicals subject to reporting under section 313 of the Emergency Planning and Community Right-to-Know Act of 1986 (EPCRA). C.I. Pigment Blue 15:1 is a mixture of C.I. Pigment Blue 15 (copper phthalocyanine) and copper monochlorophthalocyanine. C.I. Pigment Blue 15 has already been deleted from the chemical category ``copper compounds''; therefore, the Agency is treating this petition as a request to remove copper monochlorophthalocyanine from the chemical category ``copper compounds.'' This proposed rule is based on EPA's belief that the copper ion from copper monochlorophthalocyanine will not become available. In addition, EPA requests comment on the alternative of exempting all copper phthalocyanine compounds that are substituted with only hydrogen and/or bromine or chlorine from the reporting requirements under the ``copper compounds'' category in EPCRA section 313.
