The Clean Water Act requires states to regularly assess readily available water quality data and update the status of state waters. The U.S. Environmental Protection Agency (EPA) approved Washington's most recent water quality assessment in 2016.
We are in the process of a new Water Quality Assessment cycle and updating Water Quality Policy 1-11, which provides guidance for how we evaluate and assess water quality data.
Revising Policy 1-11
We conducted a public review and comment period of draft Policy 1-11 revisions from Feb. 12 – April 6, 2018. You can view the comments here.
Contact Susan Braley to request an underline/strikeout version based on 2012 Policy 1-11.

Commenting on Policy 1-11 revisions
We accepted comments on Policy 1-11 revisions until April 6, 2018 via e-comments and mail.
We hosted four public meetings to explain the changes to Policy 1-11 and answer questions:

Call for data
We conducted a second public call for data in addition to completing the Policy 1-11 public review. We sought available water quality data and information collected for fresh and marine waters in Washington for the past 10 years (Jan. 1, 2008 – Dec. 31, 2017). Data and information provided by the public was used for updating Washington’s Water Quality Assessment and was accepted until March 28, 2018.
Background information on Policy 1-11 update
In February 2016, we conducted a 60-day scoping process to solicit all stakeholder and tribal ideas about areas they think should be revised or clarified in Water Quality Policy 1-11, the Assessment of Water Quality for the Clean Water Act Sections 303(d) and 305(b) Integrated Report.
Between November 2016 and March 2017, we held several public meetings and webinars to have an open and transparent public dialogue on five key issues identified through the scoping process.
Feedback and information from the public dialogue was used to draft a revised Policy 1-11. Updates to Policy 1-11 also went through a full public review process.
