Withdrawal of Certain Federal Human Health Criteria in Washington - Final Rule

On April 16, 2020, EPA Administer Wheeler signed a final rule to withdraw certain federal Clean Water Act (CWA) human health criteria (HHC) for waters under the State of Washington’s jurisdiction. These HHC are no longer needed due to EPA’s May 10, 2019 approval of corresponding State HHC, as applicable criteria for CWA purposes for Washington’s waters. EPA determined the State’s criteria are protective of its designated uses, based on sound science, and consistent with the CWA.


Public Hearings

EPA provided a 60-day public comment period for the proposed rule to withdraw certain federal Clean Water Act (CWA) human health criteria (excluding arsenic) for waters under the State of Washington’s jurisdiction.

Additionally, EPA offered one online public hearing and one in-person hearing so that interested parties could provide oral comments on EPA's proposed rule. The online hearing was on August 28, 2019. The in-person hearing was on September 25, 2019.


Comments on the Proposal

The comment period closed on October 7, 2019.
