Hearing on marine dissolved oxygen methods
Performance-based approach methods document
May 15, 2025, 2 p.m. PT, Online webinar
We are accepting comments on the draft methods document that provides the information and process we must follow to calculate site-specific natural conditions criteria.
The hearing will begin with a brief presentation on the draft performance-based approach document and time for questions, followed by an opportunity to provide formal comments. The hearing will end once everyone who wants to provide comments has the opportunity to do so. Written comments will receive the same consideration as verbal testimony.
After registering for the meeting, you will receive a confirmation email containing information about joining the meeting, including joining by phone only.
Background
This document details the process Ecology will use to develop natural conditions site-specific criteria. It is not rule language – it supports the natural conditions provisions in the surface water quality standards. Because it is related to the Water Quality Standards, the Environmental Protection Agency (EPA) requires that we hold a comment period and public hearing whenever we make changes to it.
