Yesterday, following quickly on the heels of Governor Inslee’s withdrawal of Washington’s version of the fish consumption rule, EPA released draft water quality standards for toxics for Washington. These standards, if adopted, are significantly more stringent than those Ecology had proposed.

I have written extensively on the efforts by the Washington Department of Ecology to revise Washington’s Water Quality Standards to account for a higher fish consumption rate. This summer was when we were supposed to see the final rule be submitted to EPA for review and possible approval. In a nutshell, the controversy around this rule has to do with the upward revision in the fish consumption rate used to calculate Washington’s Water Quality Standards. That revision (from 6.5 grams per day to 175 grams per day) would result in more stringent WQS for many toxics—with the fear among dischargers being that those new criteria would be unattainable. Governor Inslee’s proposed solution—now over a year old—was to revise the excess cancer risk rate used in the WQS calculation from one in a million to one in one hundred thousand, and then couple the revised WQS with a package of regulatory efforts designed to address toxics from diffuse sources.

On Monday, right at the start of this year’s legislative session, Ecology filed its proposed rule that will–if adopted–result in adoption of new Water Quality Standards in Washington that account for high rates of fish consumption in this state.

What has changed as compared to the preliminary draft rule?

Not much, and nothing of

As directed by Governor Inslee back in July, the Washington Department of Ecology released a preliminary draft rule that will ultimately lead to the amendment of Washington’s Water Quality Standards for toxics. This is the next step in a multi-year process under which Washington is adjusting its WQS to account for a higher fish
