King County and regulators agree on consent decree modification to protect water quality under worsening climate conditions
Clean water is essential for a healthy and thriving Puget Sound region. That’s why King County is committed to making the best investments to improve water quality, protect public health and the environment, and deliver reliable benefits for local communities and ratepayers.
Our ongoing work to control sources of pollution into local water bodies during heavy rains is required by law and documented in consent decrees with the U.S. Environmental Protection Agency and the Washington State Department of Ecology.
Conditions have changed since the 2013 Consent Decree and we have now successfully negotiated modifications with our regulators.
The changes will ensure that our remaining investments in combined sewer overflow (CSO) infrastructure can be adapted for climate change, support sustainable sewer rates for the communities we serve, and prioritize work in historically underserved neighborhoods.
King County is committed to finishing this work and creating the best outcomes for water quality that will last for generations to come.
