The following information highlights the most recent actions related to the water quality standards in Washington.
Human Health Criteria
On Nov. 15, 2016, EPA partially approved and partially disapproved certain human health criteria that Ecology submitted to EPA on Aug. 1, 2016. On May 10, 2019, EPA released a statement that they are reversing their 2016 decision and approving the human health criteria standards Washington submitted in 2016. EPA will start the necessary federal rulemaking process to withdraw the federally-promulgated human health criteria.
We use the rulemaking process to meet our priorities and commitments regarding the standards.
