What other actions has EPA taken to list waste from the production of dyes and pigments prior to the last proposal?
In 1994 and 1999, EPA proposed two listing determinations for wastes from the manufacturing of organic dyes and pigments. The data on which these proposals were based contained proprietary business information that could not be released due to a court injunction. EPA did not take final action on either of these proposals. The Agency issued a new proposal in 2003 based on publicly available information and using a newly developed listing approach. The 2003 proposal and this final rule completely supersede the prior 1994 and 1999 proposals.
