EPA extended the public comment period on the proposal by 45 days in response to requests from stakeholders. Comment period is closed.
Additionally, EPA offered virtual public hearings so that interested parties may provide oral comments on EPA's proposed rule. Following a brief presentation from EPA, the Agency accepted oral comments limited to three (3) minutes per commenter so each commenter has an opportunity to present his or her views. Commenters also had the option to submit visual aids to accompany their oral comments. The hearings were recorded and transcribed, and EPA considered all of the oral comments provided along with the written public comments submitted via the docket for this rulemaking (available at Docket ID No. EPA-HQ-OW-2015-0174).

- On September 14, 2015, the EPA published a proposed rule that would revise the current federal Clean Water Act human health water quality criteria applicable to waters under the state of Washington’s jurisdiction to ensure that the criteria are set at levels that will protect fish consumers in Washington from exposure to toxic pollutants. EPA established Washington’s existing criteria for the protection of human health in 1992 as part of the National Toxics Rule, using the Agency’s recommended criteria values at the time. EPA’s proposed rule updates the fish consumption rate based on more recent regional and local fish consumption data, as well as updates the toxicity and exposure parameters, all of which are used to calculate human health criteria. The proposal also takes into account applicable EPA policies, guidance, and legal requirements.
