CSO Control Program 2012 Plan Review

Public involvement through May 2012

King County worked closely with the regional community to review its CSO Control Plan between 2010 and 2012. This review included extensive engineering, environmental, technology evaluation, economic and social impact analysis to determine if, and how, King County’s CSO Control Plan should be modified. To ensure a thorough and transparent planning process, King County held workshops and meetings to share information with interested parties and gather feedback during the review.

King County CSO Treatment Technology Workshop

The County is committed to controlling CSO’s to protect public health and the environment. As part of this work, the County is reviewing CSO treatment technologies to better understand their potential to reduce CSO pollution. The County will include promising treatment technologies in the CSO Control Plan Update it submits to the Washington State Department of Ecology in 2013.

The purpose of this workshop was to brief interested community members on the County's evaluation of treatment technologies, including the results from the County’s 2009 CSO treatment pilot, and to get input on the evaluation criteria the County will use to determine which treatment technologies to include in its 2012 Plan Update.
