Summary

EPA has taken final action to amend federal regulations to withdraw certain federal water quality criteria for lead, chlorodibromomethane, and dichlorobromomethane applicable to certain waters in California. The state now has adopted certain criteria for these parameters. EPA approved the state site-specific criteria because the Agency determined that the state criteria were scientifically sound and protective of the designated uses of these waters.

Consistent with the emphasis on state primacy for the water quality standards program, EPA has determined that the federally promulgated criteria for these parameters are no longer needed for certain waters in California. The withdrawal of the federally-promulgated criteria will enable California to implement its EPA-approved water quality standards for these parameters.
