Withdrawal of Certain Federal Water Quality Criteria Applicable to Maine

Resumen

The United States Environmental Protection Agency (EPA or Agency) proposes to amend the federal regulations to withdraw human health criteria (HHC) for toxic pollutants applicable to waters in the State of Maine. EPA proposes to take this action because Maine adopted, and EPA approved, HHC that the Agency determined are protective of the designated uses for these waters. EPA is providing an opportunity for public comment on this proposed withdrawal of federally promulgated HHC. The withdrawal would enable Maine to implement its EPA-approved HHC, submitted on April 24, 2020, and approved on June 23, 2020, as applicable criteria for Clean Water Act (CWA or the Act) purposes.
