Rule Making

Water Quality Standards for Protecting Human Health
(Fish consumption rates)
Chapter 173-201A WAC

Overview

EPA's decision - November 15, 2016

Director Bellon's response - November 15, 2016

State adopted standards - August 1, 2016

On November 15, 2016, the US Environmental Protection Agency (EPA) made a decision on Washington state’s surface water quality standards, Chapter 173-201A WAC. The decision included a partial approval and partial disapproval of our standards.

Our adopted rule

On August 1, 2016, we adopted a rule that updates surface water quality standards to include human health criteria and updated tools to implement the standards.

This rule retains the cancer risk rate (10-6) and is in keeping with the governor's directive from October 2015. It aims to protect the health of Washington’s people, fish and the economy. This work is accompanied by longstanding and continued efforts to reduce toxic threats in Washington.
