This is another in the series of guest posts authored by the consultants we work with and trust. Owen Reese is a Water Resources Engineer at Aspect Consulting approached us and offered to provide Aspect’s perspective on Ecology’s efforts to update its Water Quality Assessment for freshwater. We eagerly took Owen up on the offer because this work by Ecology has the potential to impact a number of dischargers throughout Washington State and fits well into Science Law and the Environment’s editorial goal of analyzing the intersection of science, law, and policy.
The Washington State Department of Ecology (“Ecology”) recently proposed updates to Washington’s Water Quality Assessment for freshwater, as required by sections 303(d) and 305(b) of the Clean Water Act. This list is important because it identifies which waters require water cleanup plans and could result in additional requirements for NPDES permit holders discharging to waters identified as impaired.
Ecology is seeking public comment until May 15, and is currently hosting a series of listening sessions to introduce the proposed changes in the Water Quality Assessment. The remaining sessions are: April 15 in Yakima, and April 16 in Spokane Valley. I attended the first session in Edmonds on April 7. This article summarizes my key takeaways from the presentations, with particular attention to potential effects to NPDES permittees.
