SEPA Determinations

The County is required to review projects under the State Environmental Policy Act (SEPA) as prescribed in RCW 43.21(C). Projects are reviewed under SEPA unless they fall within the exemptions of the act. All of the documents are on file in the County Planning office and are available for public inspection. Copies can be made for a nominal fee after filing a written request. The County's SEPA responsible official is the Community Development Director. The responsible official reviews the environmental checklist and makes one of three decisions known as a "threshold determination." All threshold determinations fall into one of the following cateogries: determinations of significance (DS); determinations of non-significance (DNS); or mitigated determinations of non-significance. An environmental impact statement must be prepared if a determination of significance is issued. Threshold determinations can be appealed pursuant to the provisions in the County code.  Please contact Planning Division staff if you have questions about public comment periods and appeals of SEPA determinations. You can learn more about SEPA at the Washington State Department of Ecology's website. Threshold determinations made by Walla Walla County's responsible official can be found on the Washington State DOE SEPA register.
